Overview
We are a leading, non-clinical global drug development partner with a mission to create healthier lives. We have built upon our original core competency of laboratory animal medicine and science (research model technologies) to develop a diverse portfolio of discovery and safety assessment services, both Good Laboratory Practice (GLP) and non-GLP, that supports our clients from target identification through non-clinical development. We also provide a suite of products and services to support our clients’ manufacturing activities. Utilizing our broad portfolio of products and services enables our clients to create a more efficient and flexible drug development model, which reduces their costs, enhances their productivity and effectiveness, and increases speed to market.
The development of new drugs requires a steadily increasing investment of time and money. Various studies and reports estimate that it takes between 10 to 15 years, up to $2.5 billion excluding time costs and exploration of between 10,000 and 15,000 drug molecules to produce a single Food and Drug Administration (FDA)-approved drug.
Discovery represents the earliest stages of research in the life sciences, directed at the identification, screening, and selection of a lead molecule for future drug development. Discovery activities typically extend anywhere from 4 to 7 years in conventional pharmaceutical research and development (R&D) timelines.
Development activities, which follow, and which can take up to 7 to 10 years, are directed at demonstrating the safety, tolerability and clinical efficacy of the selected drug candidates. During the non-clinical stage of the development process, a drug candidate is tested in vitro (non-animal, typically on a cellular or sub-cellular level in a test tube or multi-well petri plate) and in vivo (in research models) to establish drug safety prior to and in support of human clinical trials.
For over 75 years, we have been in the business of providing the research models required in the research and development of new drugs, devices and therapies. Over this time, we have built upon our core competency of in vivo biology to develop a diverse and expanding portfolio of products and services, which now encompasses the broader non-clinical drug research process. We are positioned to leverage our leading portfolio in non-clinical drug research in an efficient and cost-effective way to aid our clients in bringing their drugs to market faster.
Our client base includes major global pharmaceutical companies, many biotechnology companies; agricultural and industrial chemical, life science, veterinary medicine, medical device, diagnostic and consumer product companies; contract research and contract manufacturing organizations; and other commercial entities, as well as leading hospitals, academic institutions, and government agencies around the world. In recent years, we have focused our efforts on improving the efficiency of our global operations to enhance our ability to support our clients. Our pharmaceutical and biotechnology clients are increasingly seeking full service, “one-stop” global partners to whom they can outsource more of their drug discovery and development efforts. It is estimated that the market for regulated safety assessment services is 60% outsourced or more, while emerging growth areas such as discovery and certain research model services are currently believed to be less outsourced.
We currently operate in 155 sites and in over 20 countries worldwide (excluding certain Insourcing Solutions sites). Our products and services, supported by our global infrastructure and deep scientific expertise, enable our clients to overcome many of the challenges of non-clinical life sciences research. In 2023, our total revenue was $4.1 billion.
We have three reportable segments: Research Models and Services (RMS), Discovery and Safety Assessment (DSA) and Manufacturing Solutions (Manufacturing).
Through our RMS segment, we have provided foundational tools for the discovery of new molecules by supplying research models to the drug development industry since 1947. We continue to maintain our position as a global leader in the production

and sale of the most widely used research models, including over 140 different stocks and strains of purpose-bred rodents. We also provide a variety of related services that are designed to support our clients in the use of research models in drug discovery and development. We maintain multiple production centers, including barrier rooms and isolator facilities, on three continents (North America, Europe, and Asia). We are also a premier provider of high quality, purpose bred, large research models to the biomedical research community. Our RMS segment also includes our Insourcing Solutions business, which includes our CRADL (Charles River Accelerator and Development Lab) footprint. In 2023, RMS accounted for 19.2% of our total revenue and approximately 4,300 of our employees, including approximately 200 science professionals with advanced degrees.
Our DSA segment provides services that enable our clients to outsource their innovative drug discovery research, their related nonclinical and some clinical drug development activities, and regulatory-required safety testing of potential new drugs, vaccines, industrial and agricultural chemicals, consumer products, veterinary medicines and medical devices. The demand for these services is driven by the needs of large global pharmaceutical companies that continue to transition to an outsourced drug development model, in addition to mid-size and emerging biotechnology companies, industrial and agrochemical companies and non-governmental organizations that rely on outsourcing. These entities may choose to outsource their discovery, development and safety activities to reduce fixed costs and to gain access to additional scientific expertise and capabilities.
We are the largest provider of outsourced drug discovery, non-clinical development and regulated safety testing services worldwide. We have extensive expertise in the discovery of nonclinical candidates and in the design, execution and reporting of safety assessment studies for numerous types of compounds including cell and gene therapies, small and large molecule pharmaceuticals, industrial and agricultural chemicals, vaccines, consumer products, veterinary medicines, biocides and medical devices. We currently provide discovery and safety assessment services at multiple facilities located in the United States (U.S.), Canada, and Europe. In 2023, our DSA segment represented 63.3% of our total revenue and employed approximately 13,400 of our employees including approximately 1,800 science professionals with advanced degrees.
Within our Manufacturing segment, we work with our clients and the biopharmaceutical industry to ensure the quality and safe production and release of commercial therapies and products manufactured both by our clients and internally for our clients. Our Manufacturing Segment is comprised of two businesses: Microbial Solutions and Biologics Solutions. Our Microbial Solutions products and services businesses provide in vitro methods for conventional and rapid quality control testing of sterile and non-sterile pharmaceuticals and consumer products. Biologics Solutions is comprised of both our Biologics Testing Solutions business, which provides specialized testing of biologics frequently outsourced by global pharmaceutical and biotechnology companies, and our CDMO business, which provides comprehensive contract development and manufacturing solutions for cell and gene therapies. In 2023, Manufacturing accounted for 17.4% of our total revenue from continuing operations and approximately 3,000 of our employees, including approximately 400 science professionals with advanced degrees.
Research Models and Services. Our RMS segment is comprised of three businesses that provide foundational tools that enable our clients to discover new molecules: Research Models, Research Model Services and Cell Solutions.
Research Models. Our Research Models business is principally comprised of the production and sale of the most widely used small research models, primarily rodents. A significant portion of our Research Models business involves the commercial production and sale of small research models, principally purpose-bred rats and mice for use by researchers. The FDA and foreign regulatory agencies typically require that the safety and efficacy of new drug candidates be tested on research models like ours prior to testing in humans. As a result, our research models are an essential part of the drug discovery and development process.
We provide our research models to numerous clients around the world, including most pharmaceutical companies, a broad range of biotechnology companies, contract research organizations and many government agencies, hospitals, and academic institutions. We have a global footprint with production facilities strategically located in 7 countries, in close proximity to major biohubs and client concentrations. Our research models include commonly used laboratory strains, disease models and specialized strains with compromised immune systems, which are in demand as early-stage tools in the drug research and development process.
The research models we supply have been, and continue to be, some of the most extensively used in the world, largely as a result of our geographic footprint and continuous commitment to innovation, quality, and biosecurity. Our research models are bred and maintained in controlled environments, which are designed to ensure that the models are free of specific viral and bacterial agents and other contaminants that can disrupt research operations and distort scientific results. With our production capabilities, we are able to deliver consistently high-quality research models worldwide.
Our small research models include inbred, outbred, and hybrid strains, as well as mutant strains and genetically engineered models with biological features, which enable research aims. Certain of our research models are proprietary rodent models used to research treatments in several therapeutic areas. We are also a premier provider of high quality, purpose bred, large research models to the biomedical research community. While we provide some non-human primates directly to customers who utilize
3

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
them primarily for safety testing of new therapies, most of the non-human primates associated with our business are utilized in connection with our customers’ studies conducted by our Safety Assessment business. In both cases - non-human primates we provide directly to customers and non-human primates which are utilized in our Safety Assessment business – these large research models are sourced from Charles River audited and approved suppliers, some of which we have an ownership and/or operational involvement. See Note 2, “Acquisitions and Divestitures”, included in the notes to our consolidated financial statements included elsewhere in this Form 10-K for a description of the recent acquisition of Noveprim Group.
Research Model Services. RMS offers a variety of flexible solutions designed to support our clients' use of research models in basic research and screening pre-clinical drug candidates. These services address the need among pharmaceutical and biotechnology companies to outsource the non-core aspects of their drug discovery activities. Our services include those related to the maintenance and monitoring of research models, and managing research operations for government entities, academic organizations, and commercial clients. Our expanded service offering provides greater flexibility for our clients’ research and supports increased scientific complexity. We currently have three service offerings in research models services: Insourcing Solutions, Genetically Engineered Models and Services (GEMS), and Research Animal Diagnostic Services (RADS).
Insourcing Solutions. We manage the research operations of government entities, academic organizations and commercial clients (including recruitment, training, staffing and management services) both within our clients’ facilities and utilizing our Charles River Accelerator and Development Lab (CRADL™) offerings, where we provide vivarium space to our clients. Some research institutions prefer to retain certain elements of their research in-house, while outsourcing staffing and management, thus driving demand for our services. We believe that our expertise in early-stage drug research, and in particular research model care, scientific and technical support, facility operations, and discovery and development services, enhances the productivity and quality of our clients’ research programs.
Genetically Engineered Models and Services. We create, breed and maintain research models required by our clients for biomedical research activities. The creation of a genetically engineered model (GEM) is a critical scientific event, but it is only one step in the discovery process, and our scientists can advise clients on how to efficiently create custom models utilizing in-licensed technologies and approaches to modify the genome. Productive utilization of GEMs requires significant additional technical expertise in order to properly support basic and early discovery research. We provide breeding expertise and colony expansion, quarantine, health and genetic testing and monitoring, germplasm cryopreservation and rederivation, including assisted reproduction and model creation. Our team of project managers is supported by a proprietary, technologically advanced Internet Colony Management (ICM™) system that allows for real-time data exchange. We provide these services to clients around the world, including pharmaceutical and biotechnology companies, hospitals, universities, and government agencies.
Research Animal Diagnostic Services. We monitor and analyze the health profiles of our clients’ research models and research biologics by assessing infectious agents and pathology. We developed this capability internally to address the quality control of our research model business. We can serve as our clients’ sole-source testing laboratory, or as an alternative source supporting our clients’ internal laboratory capabilities. We believe we are the reference laboratory of choice for health assessment of laboratory research models and an industry leader in the field of laboratory animal diagnostics.
Cell Solutions. Our Cell Solutions business provides consenting human donor-derived cellular materials used in the development and production of cell therapies. The business supplies controlled, consistent, customized primary cells and blood components derived from normal and mobilized peripheral blood and bone marrow. Our Cell Solutions business supports biotechnology and pharmaceutical companies, academic institutions and other research organizations who rely on high-quality, viable and functional human primary cells and blood components for biomedical and drug discovery research and cell therapy development, including clinical trials.

early nonclinical pharmacokinetic and pharmacodynamic studies, transporter-mediated drug-drug interaction, and in vitro and in vivo assays to assess mechanism, bioavailability and metabolism as required for regulatory approval of new drugs;
In vivo Discovery Services, which are essential in early stage, non-clinical discovery research, and are directed at the identification, screening, optimization and selection of effective therapeutics agents in pharmacology models. These in vivo activities typically extend anywhere from 1 to 2 years in conventional pharmaceutical R&D timelines; and
target engagement biomarker development to support non-clinical and potentially downstream clinical studies.
Additionally, we offer ion channel and drug transporter testing for both discovery and non-clinical purposes. We also provide these services at our clients’ laboratories with Charles River scientists as part of an insourcing service model.
Through comprehensive in vivo and in vitro offerings, Discovery Services helps to reduce the time needed to research, develop, and assess the efficacy of new therapeutics under development. Our offerings include businesses that provide critical data to advance novel therapeutics, as well as drug transporter assays and kits. We offer R&D expertise, capabilities and services globally to accelerate our clients’ drug discovery pipelines from lead generation to candidate selection. We complement and extend clients’ capabilities and expertise to improve their decision-making, increase their flexibility, and reduce their internal costs and product development timelines.
Through strategic partnerships, we also offer an artificial intelligence drug design platform, a human stem cell model platform, and 3D in vitro oncology models.
Safety Assessment. We offer a full range of safety assessment studies required for regulatory submission on a global basis across all therapeutic areas in the pharmaceutical, biotechnology, industrial chemical, agrochemicals, consumer products, veterinary medicines and medical devices industries. Our safety assessment business also provides expertise in a variety of therapeutic areas and modalities. Our Safety Assessment business is a global leader in both non-regulated and regulated (GLP) outsourced safety assessment services.
Toxicology. We provide a broad specialty toxicology offering from inhalation and infusion to developmental and reproductive toxicology. Our services include a broad offering of in vitro and in vivo capabilities and study types designed to identify possible safety risks as well as a broad offering of in vitro and in vivo studies in support of general toxicology (acute, sub-acute and chronic studies), genetic toxicology, safety pharmacology, off-target screening, receptor identification profiling, reproductive and developmental toxicology, juvenile toxicology, and carcinogenicity bioassays that are required for regulatory submissions supporting “first-in-human” to “first-to-the-market” strategies for potential human therapeutics. Additionally, we support safety studies in numerous specialty areas including abuse and seizure liability, ecotoxicology, environmental risk, musculoskeletal toxicology, neurotoxicology, ocular toxicology, ototoxicology, and phototoxicology. We have expertise in the design and execution of development programs in support of a broad diversity of therapeutic modalities in numerous laboratory species and test systems. We also support safety studies to test industrial chemical, agrochemicals, consumer products, veterinary medicines and medical devices. For human pharmaceutical candidates, once a lead candidate is selected, toxicology studies are required to support clinical trials in humans and for regulatory approval. These toxicology studies focus on assessing the safety of the potential therapeutic to determine if administration to humans might cause any unintended harmful effects. For new chemicals, industrial chemicals, agrochemicals, veterinary medicines, consumer products and medical devices, safety studies are performed to identify potential hazards to humans and the environment and are required for regulatory registration. Toxicology studies performed for any of these compounds are typically performed using in vitro and in vivo research models to identify any potential adverse effects that a compound has on an organism over a variety of doses and over various time periods of exposure.
Pathology Services. The ability to identify and characterize clinical and anatomic pathologic changes is critical in determining the safety and efficacy of potential new therapeutics, industrial and agricultural chemicals, veterinary medicines, and medical
5

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
devices. Key “go/no-go” decisions regarding continued product development are typically dependent on the identification, characterization and evaluation of fluid, tissue and cellular changes that our experts identify and interpret for our clients. We employ many highly trained veterinary anatomic and clinical pathologists and other scientists who use state-of-the-art techniques to identify potential test item-related changes. In addition to all standard anatomic and clinical pathology techniques, we provide specialized evaluations such as cytology, platelet function, assay development, immunohistochemistry, in situ hybridization, electron microscopy, image analysis, tissue morphometry and spatial analysis services.
Safety Pharmacology. Our clients are also required to conduct an assessment of safety pharmacology. This suite of studies is used to determine any effects on the vital organ systems of the body - cardiovascular, respiratory and central nervous system (CNS). Along with heart rate and blood pressure measurements, the cardiovascular assessment will also assess if the test article has the potential to alter cardiac ion channel currents and prolong the cardiac QT interval of the electrocardiogram. Additionally, effects on the CNS and respiratory systems are assessed to complete the battery of studies to evaluate the vital organ systems of the body. Supplemental studies can also be performed to assess the renal, gastrointestinal and autonomic nervous systems, as well as dependency potential. We have in vitro, ex vivo (use of cells, tissues or organs outside of an in vivo system) and in vivo assays and perform the screening prior to the initiation of first-in-human clinical trials. Our capabilities can also be used to investigate the mode of action behind an adverse effect found in a safety assessment study.
Bioanalysis, Drug Metabolism and Pharmacokinetics. In support of non-clinical drug safety testing and new chemical development, our clients are required to demonstrate appropriate stability in the collected biological sample, pharmacokinetics of their drug or compound in circulation, the presence of metabolites and, in the case of biologics, the presence or absence of anti-drug antibodies. We have scientific expertise in the sophisticated bioanalytical techniques required to satisfy these requirements for many drugs and chemicals. Once analysis is complete, our scientists evaluate the data to provide information on the pharmacokinetics and/or toxicokinetics of the drug or chemical and complete an evaluation of the biologic disposition of the drug or chemical and its potential metabolites. Pharmacokinetics refers to the understanding of what the body does to a drug or compound administered at therapeutic dose levels, including the process by which the drug is absorbed, distributed in the body, metabolized and excreted. Toxicokinetics refers to the same understanding as applied at higher doses that may result in adverse effects. These studies are routinely required for the full non-clinical assessment of the disposition of the drug or chemical and the results are used in the safety evaluation of the compound. After performing sample analysis in support of non-clinical studies, we also support the clinical bioanalysis required in clinical trials for drug development. In addition, our Laboratory Sciences group is able to measure a wide range of nonclinical and clinical biomarkers related to the safety and efficacy of the drugs and/or chemicals being developed.
Our Safety Assessment facilities comply with animal welfare requirements and GLP to the extent required by the FDA, Environmental Protection Agency, United States Department of Agriculture (USDA), European Medicines Agency, European Chemicals Agency and the Organization for Economic Co-operation and Development (OECD), Canadian Council on Animal Care (CCAC) as well as other international regulatory agencies. Furthermore, our early-stage discovery work, which is not subject to GLP regulations, is typically carried out under a quality management system. Our Safety Assessment facilities and Manufacturing facilities are regularly inspected by U.S. and other regulatory compliance monitoring authorities, our clients’ quality assurance departments and our own internal quality audit program.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
extraction of the raw materials for LAL does not harm the crabs, which are subsequently returned to their natural ocean environment. We have worked closely with regulatory agencies in states where we collect to limit our impact on the horseshoe crab population.
One of the primary growth drivers in our Microbial Solutions business is our FDA-approved line of next-generation endotoxin testing products. This line is based on the Endosafe Portable Testing System (Endosafe® -PTS™) technology, which allows rapid endotoxin testing in the central laboratory or manufacturing environment. In recent years, we expanded the PTS product portfolio to include a multiple sample testing system known as the Endosafe®-MCS™ (multi-cartridge system) and the first fully automated robotic system developed specifically for high-volume endotoxin testing, Endosafe®-Nexus, to satisfy the demand of our clients who require higher sample throughput. We have seen expanded use of this rapid endotoxin testing technology as clients transition from traditional methods to our rapid cartridge technology and are seeking to meet data integrity requirements with our automated systems and software solutions. We recently launched Endosafe® Trillium®, our new animal-free recombinant test for endotoxin detection. Endosafe® Trillium® utilizes three biological proteins, which we believe provides superior accuracy and testing outcomes to competitors’ single-protein recombinant alternatives, as well as equivalence to LAL-based testing method. Endosafe® Trillium® represents a next-generation solution to our industry-leading Endosafe® bacterial endotoxin detection portfolio.
Celsis®. The Celsis® reagents and instrument systems are used for in-process and product-release testing to help ensure the safe and efficient manufacture of pharmaceutical and consumer products. Celsis® products utilize adenosine triphosphate bioluminescence technology for the rapid detection of microbial contamination delivering definitive results for some applications as fast as 24 hours. The product range includes reagent kits, instruments, software and services. The Celsis Advance II™, Celsis Accel™, and Celsis Adapt™ instruments and software automate the process for rapid microbial detection. We maintain a suite of products focused on sterility testing. Sterility testing is required prior to the release of sterile injectable products. The legacy method required a 14-day sample incubation period and was subjective. Using the Celsis® protocol and instrumentation, clients can detect contamination within 6 days and make definitive product release decisions. We also offer Celsis Complete™ and Celsis Advantage™ services. The Celsis Complete™ services supply both the documentation and testing required as part of a client sterility technology method validation process. This assists clients to complete their validation process very quickly without utilizing their own personnel resources. The Celsis Advantage product supplies the required documentation needed for the clients to conduct their own internal validation. The Celsis Adapt™ is an accessory instrument for the Celsis® rapid detection systems, which is used to prepare and concentrate samples and provide a rapid testing solution for advanced therapy medicinal products, cell therapies, gene therapies, and other cell-containing products.

Our CDMO business operates in the three major areas of the high-growth advanced therapy CDMO market: cell therapy, viral vector, and plasmid DNA production. Our CDMO services include expertise in gene-modified and unmodified cell therapy manufacturing coupled with capabilities in viral vector manufacturing, as well as plasma DNA. Our CDMO services establish us as a premier scientific partner for cell and gene therapy development, testing, and manufacturing. The full integrated advanced therapeutics portfolio enables us to provide clients with an integrated solution from basic research and discovery through cGMP production; driving efficiency and accelerating clients’ speed-to-market by integrating preclinical CRO activities with manufacturing and testing. This provides our clients with a seamless experience across the value chain with the same advanced therapeutics scientific partner. Our cGMP CDMO facilities have the capability to manufacture and store raw materials, drug substance, and drug product, which are suitable for use in clinical trials as well as for commercial manufacturing.
Our Strategy
Our objective is to be the scientific partner of choice to accelerate biomedical research and therapeutic innovation. Our strategy is to deliver a comprehensive and integrated portfolio of drug discovery and non-clinical development products, services and solutions to support our clients’ discovery and early-stage drug research, process development, scale up, manufacturing and product release efforts, and enable them to bring new and improved therapies to market faster and more cost effectively.
We believe we have certain competitive advantages in executing this strategy because of our continuing focus on the following:
Integrated Early-Stage Portfolio. Our large, global portfolio of products, services and solutions focuses on drug discovery and early-stage development. We provide research models and associated services, discovery research studies and services and comprehensive safety assessment studies in both regulated and non-regulated environments. As such, we can collaborate with clients from target discovery through development candidate selection. When critical decisions are made regarding which therapeutics will progress from discovery to development, we continue to work alongside our clients as the drug candidates move downstream. Our recognized expertise in early-stage drug research and pharmacology provides us with a competitive advantage and enables our clients to make critical drug development decisions more quickly. We understand our clients’ therapies and the challenges they face during the discovery and development process, including mechanism of action, efficacy, drug metabolism, safety assessment and toxicological testing, which are all critical for making “go/no-go” decisions.
Comprehensive Biopharmaceutical Manufacturing Portfolio. We also offer a portfolio of products, services and solutions that supports the process development, scale up, quality control and production efforts of the biopharmaceutical industry. We provide products and services that support the development and release of clinical stage and commercialized biologics products, including CDMO services to manufacture advanced therapeutics for our clients. In particular, we are an industry leader in the areas of microbial detection and microbial identification to support process development and ongoing commercial production. Our portfolio spans a broad range of traditional and rapid methods, which provide the highest testing quality, enhanced productivity and reduced cycle time.
Deep Scientific Expertise. We provide a breadth and depth of scientific expertise across a broad range of therapeutic areas which may be too costly for our clients to build and/or maintain in-house. We provide essential capabilities, including medicinal chemistry, antibody engineering, in vitro biology, in vivo pharmacology, pathology, advanced modalities manufacturing, analytical testing for early and late stage products, immunology, biomarker assessment, biologics process development testing, microbial detection and identification and other specialty service areas that have high infrastructure costs or are cost-prohibitive for clients to maintain independently. We continue to expand our portfolio in key therapeutic and pharmacology areas to align with our clients’ internal drug discovery and development areas of focus. We also continue to enhance our small molecule, biologics, and advanced modalities portfolios in areas of greatest industry need, where outsourcing provides major benefits for our clients and where we could provide significant benefits given our unique early-stage development portfolio and global footprint.
Commitment to Animal Welfare. We are committed to being the worldwide leader in the humane care of research animals and implementation of the “4Rs” initiative (Replacement, Reduction, Refinement, and Responsibility). As researchers, we are responsible to our clients, our animals and the public for the health and well-being of the animals in our care. We work closely with the scientific community to understand how living conditions, handling procedures and reduction of stress play an important role in the quality and efficiency of research. We are committed to working with the industry to support development and to provide the best translational models to supplement or replace traditional models. These include in vitro models as well as in silico predictive tools. In the last 4 years, we have
8

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
invested approximately $200 million in alternative methodologies, including technologies and digital platforms that reduce/modify animal use via strategic acquisitions, partnerships, and internal investments.
Superior Quality and Client Support. We maintain scientific rigor and high-quality standards through management of key performance indicators and an intense focus on biosecurity and quality. These standards help to reduce research risk and allow clients to access our global portfolio of products and services with the confidence that they will obtain consistent results no matter where they choose to obtain their products or conduct their research.
Flexible and Customized Environment to Provide the Right Solutions. Each of our clients is different, with unique needs and specific requirements. We understand the importance of flexibility, and leverage the expertise embedded in our integrated, non-clinical portfolio to provide customized solutions tailored to the specific need or therapeutic area for a particular client. By utilizing our streamlined and efficient facilities, we help clients create a flexible and integrated infrastructure in order to improve their workload and staffing requirements. This allows our clients to optimize internal capacity and/or staff while ensuring the conduct of effective quality research for their projects. We provide enhanced value to clients who use us as a full-service integrated partner over a longer period of time.
Large, Global Partner. We believe there is an important advantage in being a full service, high-quality provider of research models and associated services, discovery and non-clinical in vivo and in vitro services and manufacturing solutions on a global scale. Many of our clients, especially large biopharmaceutical companies, have decided to limit the number of suppliers with which they work. They frequently choose to partner with large companies similar to Charles River, that can offer clients support across the non-clinical drug research process as a result of broader portfolios and experience in project management. This includes extensive scientific, technical and therapeutic area expertise, real-time access to data, documentation and data visualization through secure portals, provision of data in sponsor-specific formats for data warehousing needs, accelerated reporting, reduced standard reporting timelines and industry-leading Standard Exchange of Non-Clinical Data (SEND) capabilities, a global footprint, streamlined and simplified processes and communications, including professional project and relationship management. We are focused on leveraging our competitive advantages to ensure we are recognized as the premier preferred provider, thereby enabling us to build broader and deeper long-term strategic relationships with our clients.
Digital Enhancements. We believe the healthcare industry is at a unique inflection point post COVID, where vaccines and treatments were developed in record time, and there is increasing focus on personalized medicine and rare diseases. As the industry evolves, technology is playing an essential role. This technological revolution is not only helping streamline processes and operations, but the effects of this digitization directly impact patients. We are committed in our efforts to reduce the timeline to develop, safe and innovative new treatments for patients who desperately need them. To progress this forward, we strive to understand the true challenges that can slow drug research and development and re-imagine the way we work and collaborate to create digitally native solutions that improve efficiency, accelerate processes and enable automated, data driven outcomes. Our commitment to understanding the problem before finding a solution has enabled us to keep clients—and ultimately patients—at the center of the way we look at problems. By using client-centric design thinking, agile-based test and learn processes in short iterative cycles, and automating existing processes, we optimize client experiences and bring holistic solutions to pressing concerns.
Our clients’ R&D needs continue to evolve. These clients are increasingly emphasizing studies that have greater translation to the clinic so that they can make appropriate decisions regarding the progression of potential therapeutic entities earlier in the development process. The result is a focus on discovery services, including in vitro models and in vivo pharmacology studies consisting of efficacy and non-GLP DMPK (drug metabolism and pharmacokinetics) studies. Second, these clients are choosing to outsource additional discovery and safety assessment services to increase the efficiency and effectiveness of their drug selection processes.
We believe that this changing environment will provide enhanced outsourcing opportunities for us in the future. We remain optimistic that our clients are increasingly receptive to partnering with us as a means of meeting their discovery and non-clinical support needs. We believe that the successful development of new therapies and outsourcing by the pharmaceutical industry will continue to be positive drivers of demand for our products and services.
Global biopharmaceutical companies are continuing to make the decision to outsource more significant tranches of their drug discovery, development and manufacturing processes. The success of our business model is underscored by the fact that we have entered into strategic commercial relationships with leading global biopharmaceutical companies and expanded existing preferred provider agreements with other leading global biopharmaceutical companies. We also continue to broaden and extend our relationships with other research institutions across the portfolio.
We believe that larger biopharmaceutical companies will increasingly focus on efficiencies and execution. They will continue to reassess their core differentiators from R&D to commercialization, and which aspects of their drug discovery, development
9

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
and manufacturing processes they will choose to outsource. We expect they will also continue to be conservative in re-building infrastructure and expertise. This should lead to more opportunities for strategic outsourcing as larger pharmaceutical clients choose to utilize external resources rather than invest in internal infrastructure. By partnering with Charles River, we believe our clients can take advantage of efficiencies in their early-stage research activities that can result in months saved in getting a drug to market. In the aggregate, we believe that the evolving large biopharmaceutical R&D business model along with our focus on data and digitalization will make our essential products and services even more relevant to our clients, and allow them to leverage our integrated offerings and expertise to drive their research, non-clinical development and manufacturing efficiency and cost effectiveness.
We believe it is critical to participate in the strategic commercial partnering process because these relationships are likely to extend for multiple years and drive pull-through across our portfolio. Furthermore, both the client and Charles River invest heavily in the initial phases of the relationship to successfully transfer work streams and establish governance processes. Given this investment, clients are less likely to change partners at the conclusion of the initial relationship.
The evolving biopharmaceutical R&D business model, coupled with solid long-term biopharmaceutical industry fundamentals and a historically sustained funding environment, have also led to the continued creation of new biotechnology companies focused on developing innovative new therapies. The biopharmaceutical industry also continues to evolve and become more sophisticated, with research yielding new types of treatments with increasing complexity, and more targeted and individualized therapies. We believe that our portfolio provides flexible solutions and scientific expertise that meet the customized needs for virtual and small biotechnology companies, which have limited or no infrastructure. These clients also value our ability to provide a broad range of services where we work hand in hand with our clients to design, plan and manage integrated projects and programs. This includes classically outsourced services, “insourced” services and hybrid offerings blending resources from both our clients and our staff.
Our strategic imperatives and operational goals are centered around our intense focus on initiatives designed to allow us to drive profitable growth, enhance our operating efficiency and cost structure and better position ourselves to function successfully in the current and future business environment, which we believe will collectively enable us to maximize value for our shareholders.
In recent years, we have expanded our service capabilities into the high-growth, high-science sector of cell and gene therapy. Our goal is to deliver the fastest and highest quality end-to-end integrated solution to accelerate cell and gene therapy development and manufacturing globally by leveraging our comprehensive portfolio of cell and gene therapy capabilities with a consistent, easy-to-use, and customizable, high-science approach, while offering the flexibility to adapt and innovate to meet our client’s changing needs. In the cell and gene therapy sector, we aim to accelerate our clients’ path to market, to expand capabilities and geographic reach to complement our leading non-clinical portfolio, and to collaborate with our clients and partners to enable and commercialize the next generation of cell and gene therapy innovations. Our CDMO capabilities, combined with our comprehensive portfolio, most notably our Biologics Testing Solutions business, industry experience, and established infrastructure, helped solidify Charles River as a premier scientific partner for cell and gene therapy development, testing, and manufacturing.
We intend to continue to broaden the scope of the products and services that we provide across the drug discovery and non-clinical development continuum primarily through internal development, and, as needed, through focused acquisitions and partnerships. Acquisitions, such as our acquisitions of Distributed Bio, Retrogenix, Cognate, and Vigene in fiscal 2021, Explora BioLabs in fiscal 2022, and SAMDI and Noveprim in 2023, are an integral part of our growth strategy, both to expand our portfolio and broaden our geographic footprint. We are committed to a disciplined approach that seeks to target businesses that are a sound strategic fit. We aim to consistently deliver shareholder value, including the achievement of a hurdle rate for return on invested capital above our weighted average cost of capital.
Mergers, acquisitions, and partnerships remain one of our top, long-term priorities for disciplined capital deployment and enhancing growth strategy with focus on enhancing the breadth of our scientific capabilities, expanding our global scale, and maintaining our leadership position in advanced and emerging therapies. Our long-term strategy also includes growth through establishing relationships and exploring other opportunities and areas that have the potential to strengthen our broad-based portfolio of products and services. In particular, our focus has been to drive differentiation through technologies that enhance the speed to develop a clinical candidate and allow biopharmaceutical companies to make earlier go/no-go decisions. Among other arrangements, these relationships may include entering into license agreements, strategic technology partnerships or joint ventures that will allow us to access innovative capabilities and cutting-edge or nascent technologies with a modest investment component. Our ability to thoroughly assess these technologies and market opportunities may later result in an acquisition.
We also partner with a diverse set of leading venture capital firms around the world primarily investing in life sciences, health care and therapeutics with an emphasis on early-stage companies. Through these partnerships and close relationships, we gain insight into their company and asset portfolios and are thus able to promote our services for each of our businesses. We also view these partnerships as an investment in new and emerging sciences and technologies as they allow us to gain insights to
10

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
cutting-edge capabilities. Thus, we have the opportunity to establish ourselves as a provider of choice for a unique client group that has emerged as biopharmaceutical companies rationalize and prioritize their development pipelines.
We routinely evaluate strategic fit and fundamental performance of our businesses. As part of this ongoing assessment, we may determine certain capital could be better deployed in other long-term growth opportunities. Most recently, we divested our Avian Vaccine Services business in 2022, and RMS Japan and CDMO Sweden operations in 2021, as we determined these businesses were no longer a strategic fit.
Clients
Our clients consist primarily of major biopharmaceutical companies; many biotechnology, agricultural and industrial chemical, life science, veterinary medicine, medical device, diagnostic and consumer product companies; contract research and contract manufacturing organizations; and other commercial entities, as well as leading hospitals, academic institutions and government agencies. We have stable, long-term relationships with many of our clients. During 2023, no single client accounted for more than 3.5% of our total revenue and no single client accounted for more than 8% of the revenue of any of our three business segments.
We continue to pursue a goal of expanding our relationships with our large biopharmaceutical clients, and with many of our larger mid-market clients. These relationships take different forms, from preferred provider arrangements to strategic partnerships. The structure of these relationships incentivizes clients to purchase more products and services across our non-clinical portfolio. Because of the strength of these relationships, we have better insight into our clients’ planning processes and, therefore, better visibility than in the past. For information regarding revenue attributable to each of our business segments for the last three fiscal years, please see Note 4, “Segment and Geographic Information” included in the Notes to Consolidated Financial Statements included elsewhere in this Form 10-K. For information regarding revenue and long-lived assets attributable to operations in the United States, Europe, Canada, Asia Pacific and other countries for each of the last three fiscal years, please review Note 4, “Segment and Geographic Information” included in the Notes to Consolidated Financial Statements included elsewhere in this Form 10-K.
Sales, Marketing and Customer Support
Our marketing efforts are focused on stimulating demand for further outsourcing across our entire services portfolio. We believe that our ability to provide solutions that address all aspects of early-stage drug research are increasingly attractive to our clients, and we continue to design and market our commercial activities to deliver flexible, customized programs designed by segment to meet our clients’ global and site-specific needs.
Our go-to-market approach employs a number of sales and marketing strategies, including dedicated sales teams for each of our major lines of business and global and key account managers who represent the entire portfolio. We also maintain several sales specialists that either have specific technical expertise (often degreed scientists) or cover unique markets.
In addition to our field sales teams and related specialists, we also have a team of alliance managers who are organized by key client within our market segments (global biopharmaceutical, small and mid-sized pharmaceutical and biotechnology companies, and academic and government institutions). This enhances our ability to meet client needs by offering customized, tailored solutions across our entire portfolio. In addition, our clients benefit by additional support from a combination of technical specialists with specific scientific and therapeutic area expertise. We also apply the use of dedicated sales specialists for certain technical product lines, such as in our Manufacturing businesses.
We sell our products and services principally through our direct sales and business development teams who work in North America, Europe and Asia. In addition to interactions with our direct sales force, our primary promotional activities include presenting scientific symposia to targeted audiences, publishing scientific papers, technical support pieces and white papers, and newsletters, hosting webinars and virtual seminars and making presentations at, and participating in, scientific conferences and trade shows in North America, Europe and Asia. We supplement these scientifically based marketing activities with digital marketing, advertising and website content. In certain areas, our direct sales force is supplemented by international distributors and agents.
Our internal strategic marketing and marketing operations teams support the field sales and business development teams while developing and implementing programs to build awareness about products and services and create opportunities for interaction with our clients in the biomedical research industry. We maintain client engagement, lead development support, digital experience, eCommerce, and event management departments, which address both our clients’ routine and more specialized needs and purposely serve as a scientific support and information resource for them. We frequently assist our clients in solving problems related to resourcing products and services, research support, non-clinical study design, regulatory consulting, protocol development and other areas in which our expertise is widely recognized as a valuable resource by our clients.

Competition
Our goal is to be a leader in each of the markets in which we participate. We compete in the marketplace on the basis of our therapeutic and scientific expertise in early-stage drug research, quality, reputation, flexibility, responsiveness, pricing, innovation and global capabilities. We are able to offer a unique portfolio of early-stage products and services to support drug discovery and development.
We encounter a broad range of competitors of different sizes and capabilities in each of our three businesses segments. We also face competition from the internal discovery and development resources of our clients.
For RMS, we have four main competitors of which one is a government funded, not-for-profit entity; one is a public company in the U.S.; one is privately held in Europe; and one is privately held in the U.S.
For DSA, both our Discovery Services and Safety Assessment businesses have numerous competitors. Discovery Services has hundreds of competitors, but two main competitors: one is a public company in China and one is a public company in Europe. Safety Assessment has dozens of competitors of varying size, but one main competitor that is a division of a large public company in the U.S. Our DSA segment also competes with in-house departments of pharmaceutical and biotechnology companies, universities and teaching hospitals.
For Manufacturing, each of our underlying businesses has several competitors. Microbial Solutions has four main competitors, of which three are public companies in Europe and one is a private company in the U.S. In addition to many smaller competitors, Biologics Solutions has five main competitors, of which three are public companies in the U.S., one is a public company in Europe, and one is a public company in China.
Industry Support and Animal Welfare
One of our core values is a concern for, and commitment to, animal welfare. Research animals are an important resource that further our knowledge of living systems and contribute to the discovery of life-saving drugs and procedures. We work hand-in-hand with the scientific community to understand how living conditions, handling procedures and stress play a role in the quality and efficiency of research. As researchers, we are responsible to our clients and the public for the health and well-being of the animals in our care.
We have been in the forefront of animal welfare improvements in our industry, and continue to show our commitment with special recognition programs for employees who demonstrate an extraordinary commitment in this critical aspect of our business. We created our own Humane Care Imperative (HCI), which is overseen by our Global Animal Welfare and Training corporate group. The goal of HCI is to ensure that we continue as a worldwide leader in the humane care of research animals and implementation of the 3Rs (Replacement, Reduction, and Refinement). In 2023, we added a fourth “R” to the longstanding 3Rs framework - Responsibility.
We are firmly committed to the 4Rs and to reducing the number of animals that we work with by emphasizing health, research animal behavioral management programs and genetic integrity to decrease study data variability. Whenever possible, we use technological advances such as new in vitro diagnostic tests for screening pathogens in laboratory rodents, microsampling and various in vitro assays. We support a wide variety of organizations and individuals working to further animal welfare and the 4Rs, as well as the interests of the biomedical research community. We also partner with clients to develop study designs decreasing the number of animal models needed and suggesting pilot studies where appropriate. We maintain a quarterly award program that recognizes our employees’ efforts to continually implement the 4Rs at our sites globally.
We provide scholarships for training in laboratory animal science, financial support to non-profit organizations that educate the public about the benefits of animal research and awards to outstanding leaders in the laboratory animal science field and the supporters of 4Rs.
In 2023, we established the management Office for Responsible Animal Usage to oversee responsible animal utilization and reduction practices, and operating standards of care. Our Board of Directors also established a new Responsible Animal Use Committee to assist the Company in improving our impact on responsible animal utilization, including evaluating and advising scientific and technological opportunities which may appropriately reduce the impact of animals in the Company’s operations. Additionally, in 2023 we committed to report to shareholders on an annual basis, beginning in 2024, on the measures the Company takes to reinforce confidence that the NHPs we import are purpose-bred.
Human Capital Resources
Employees
As of December 30, 2023, we had approximately 21,800 employees (including approximately 2,600 science professionals with advanced degrees, including Ph.D.s, D.V.M.s and M.D.s). Approximately 20,000 of our employees are considered full-time
12

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
employees, while approximately 1,400 are considered part-time employees. Our workforce was distributed geographically approximately as follows: 63% in North America, 30% in Europe, 4% in Asia, and 3% in other regions.
Our employees are not unionized in the U.S. Employees at some of our European facilities are represented by works councils, employee representative groups and/or unions, which is consistent with local customs for our industry. We collaborate with the works councils and believe we have good relationships with our employees.
Values
At Charles River, our values of Care, Lead, Own, and Collaborate guide our decisions and actions; they are standards we hold ourselves to each and every day and are critical to success in fulfilling our goals. In addition, our Charles River DNA are the behaviors based on these values that we use to make decisions, grow our future leaders, and pave the way for years ahead.
Talent Management and Engagement
Sustaining our company culture is a vital part of our strategy. Our culture is built on trust, inclusion, accountability, respect, and well-being. Our objective is to enable colleagues to connect with their work in a way that supports each other, our clients, and our communities. We strive to maintain an environment wherein every person has the ability to deliver on business commitments, while having purpose, being energized, continuously learning, and delivering quality outcomes that make a difference. Recently, we developed a unique employer brand that is infused in other aspects of our employee experience and in the past year, we have trained 1,400 managers on our inclusive hiring approach utilizing behavioral based interviewing that is aligned to our Charles River DNA. We pride ourselves on supporting our people both professionally and personally throughout their employee experience with us.
In order to attract, onboard, support, and retain such great talent, we provide our employees with opportunities for skill building and career advancement. Beginning with our onboarding program, our talent management approach is structured to be highly collaborative, encourages ownership, and provides the opportunity to contribute and develop through regular performance conversations, annual goal setting, and ongoing feedback. Furthermore, we have created a global learning strategy that includes technical training, mentoring and coaching approaches, tuition reimbursement, sabbaticals, leadership development programs, and on-the-job training. In fiscal 2023, we hired over 3,700 people and our voluntary turnover for all employees was approximately 11.5%. Additionally, we conduct regular talent reviews to identify and develop diverse leadership and key talent pipelines to deliver on short-term and long-term business strategy.
Our engagement surveys are in the form of frequent, shorter engagement “Pulse” surveys. These Pulse surveys were issued twice during 2023 and serve as a foundation for more meaningful conversations and actions between our people and people leaders to continue making Charles River a best place to work, learn, and grow.
In addition to growth opportunities, we strive to attract, motivate, and retain top talent by providing competitive compensation programs while rewarding outcomes and behaviors that align with our performance, culture, and values. While we perform pay equity audits in countries where they are legally required, we also perform a larger pay equity analysis on a global scale and take corrective action where appropriate as part of our continuing efforts to be competitive in the marketplace. Furthermore, our global job architecture generally allows for aligning pay by job role with market rates and serves as a career path tool to encourage a culture of advancement.
Health and Safety
We promote a healthy and safe workplace for our employees. We maintain a Global Policy on Safety & Sustainability and, as part of our efforts to promote our goals of working safely and sustainably, in early 2020 we implemented a management systems approach to improve our safety performance, which involves both employee and management engagement in and ownership of our site-level environment, health, safety, and sustainability programs globally. At every Charles River site globally, we have health and safety leaders that promote employee health and safety and keep site management engaged in their health and safety programs. We launched a Safety-First Culture initiative in 2022 to ensure that every person working for and on behalf of Charles River recognizes the importance of putting safe working practices first. As part of this campaign, all sites were requested to form safety committees comprised of both management and employees, initiate site safety champion recognition programs and all site general managers attended safety culture training as did many of our key executives. We also launched the first module of our people leader safety culture training and initiated a formal Environment, Health, Safety and Sustainability Assessment program with 12 site assessments in 2023.
Diversity, Equity and Inclusion
We are also committed to cultivating a welcoming and inclusive environment where every employee can succeed and thrive. Operating in 155 sites and in over 20 countries worldwide (excluding our Insourcing Solutions sites), we believe in treating our employees and prospective talent with dignity, decency, and respect. We recognize that employee diversity contributes to a more innovative workforce and see diversity and inclusivity as a strength for our business. Our commitment to equity spans
13

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
across our employment-related decisions, from hiring and promotions, to succession planning, compensation, performance, training and career development programs. Our aim is to continue to build a talented workforce reflective of the global communities in which we live and work, and it is critical that our people feel like valued members of our Company. We believe that we have taken positive steps to promote a sense of belonging for our employees in the workplace by building a Diversity, Equity & Inclusion team and Chief Executive Officer-chaired Diversity, Equity and Inclusion council; expanding diverse representation at our Board level; launching employee resource groups; facilitating training on mitigating unconscious bias and creating inclusion for our people leaders and talent acquisition teams; and rolling out a diverse candidate slates and diverse interview panel initiatives. We have also set goals to increase our belonging scores on our engagement surveys and increase participation in our employee resource groups. In addition to our internally focused efforts, we also actively engage with our clients and suppliers to share best practices. As of December 30, 2023, women made up approximately 60% of our global workforce, 59% of our U.S. workforce and 42% of our global executive leadership positions, defined as positions carrying the title of Vice President or higher. From our U.S. workforce, 32% identified as racial and ethnic minorities.
Backlog
Our backlog for our RMS, DSA and Manufacturing reportable segments was approximately $489 million, $2.5 billion and $143 million, respectively, as of December 30, 2023, as compared to $282 million, $3.1 billion and $116 million, respectively, as of December 31, 2022. Related services are performed over varying durations, from short to extended periods of time, which may be as long as several years. We maintain an order backlog to track anticipated revenue from studies and projects that either have not started, but are anticipated to begin in the near future, or are in process and have not been completed. We only recognize a study or project in backlog after we have received written evidence of a client’s intention to proceed. Canceled studies or projects are removed from backlog.
We believe our aggregate backlog as of any date is not necessarily a meaningful indicator of our future results for a variety of reasons. First, studies vary in duration (i.e., some studies or projects that are included in December 30, 2023 backlog may be completed in 2024, while others may be completed in later years). Second, the scope of studies or projects may change, which may either increase or decrease their value. Third, studies or projects included in backlog may be subject to bonus or penalty payments. Fourth, studies or projects may be terminated or delayed at any time by the client or regulatory authorities for a number of reasons, including the failure of a drug to satisfy safety and efficacy requirements, or a sponsor making a strategic decision that a study or service is no longer necessary. Delayed contracts remain in our backlog until a determination of whether to continue, modify or cancel the study has been made. We may not be able to realize all or most of the net revenues included in backlog or estimate the portion to be filled in the current year. Refer to Item 1A, “Risk Factors” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosed herein for our assessment of certain relevant risk factors.
Regulatory Matters
As our business operates in many distinct regional environments and in a variety of locations worldwide, we are subject to numerous, and sometimes overlapping, regulatory requirements.
The Animal Welfare Act (AWA) governs the care and use of certain species of animals used for research in the U.S. other than laboratory rats, mice and fish bred for use in research. As a result, most of our U.S. small animal research model operations are not subject to regulation under the AWA. For regulated species, the AWA and the associated Animal Care regulations require producers and those working with regulated species to provide veterinary care and to follow specific husbandry practices such as cage size, shipping conditions, sanitation and environmental enrichment to ensure the welfare of these animals. Separately, facilities using live vertebrate animals in research funded by the U.S. Public Health Service (PHS) must also adhere to the PHS Policy on Humane Care and Use of Laboratory Animals and follow “The Guide for the Care and Use of Laboratory Animals” published by the Board on Animal Health Sciences, Conservation, and Research.
We comply with licensing and registration requirement standards set by the USDA and U.S. Fish and Wildlife Service (USFWS), and similar applicable agencies in other global regions such as Canada, Europe and China for the care, handling and oversight of regulated species. Our DSA and RMS facilities that work with or produce research animals in North America and Europe are accredited, with the exception of new and recently acquired facilities that are in the process of planning for accreditation, by AAALAC International, a private, nonprofit organization that promotes the humane treatment of animals in science and education through voluntary accreditation and assessment programs.
Our import and export of animals and our operations in foreign countries are subject to applicable international agreements and conventions, as well as a variety of national, regional and local laws and regulations, which establish the standards for the humane treatment, care, handling and transport of animals by dealers and research facilities. We only use accredited and experienced transporters for importing and exporting animals who are specialists in their field. We comply with global requirements which are evaluated by import and export authorities at each point of exit and entry. Imported animals are

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
quarantined in our quarantine facilities as required by government agencies and tested to ensure they meet both the government mandates and our own specifications for pathogens and health of the animals.
We conduct non-clinical safety assessment studies to support the submissions for approval or licensing of our clients’ products throughout the world. Many of these studies must comply with national statutory or regulatory requirements for GLP. GLP regulations describe a quality system for the scientific, operational and quality process and the conditions under which non-clinical studies are planned, performed, monitored, recorded, reported and archived. GLP compliance is required by such regulatory agencies as the FDA, European Medicines Agency, Medicines and Healthcare Products Regulatory Agency in the United Kingdom (U.K.), Health Products Regulatory Authority in Ireland, Health Canada and other similar monitoring authorities in the countries where we operate. GLP requirements are significantly harmonized throughout the world and our laboratories are capable of conducting studies in compliance with all applicable requirements.
Regulatory monitoring authorities such as the FDA, Medicines and Healthcare Products Regulatory Agency and OECD countries have indicated an increased emphasis on the management of electronic records and signatures generated by computerized systems to ensure data integrity. We have established corporate data integrity governance to manage regulatory requirements and client expectations regarding data quality within our regulated businesses. Although each business has a different impact on patient safety, all are expected to generate and preserve data with integrity. We recognize the importance of generating quality, reliable, sustainable data and have instituted several processes and established a global governance team with oversight responsibilities for our Data Integrity Compliance Plans to ensure we are consistent in our approach. To ensure that we have proper regulatory oversight over our electronic records, a dedicated quality function reviews our computerized system practices to ensure that appropriate record controls are in place and that a robust audit strategy confirms requirements are met for compliance.
At a global level, retention of data and controls for electronic systems, proprietary data and quality standards are covered by global policies. We also have controls in place such as quality manuals, policies and procedures, work instructions, document control processes, training, quality assurance and quality control processes and personnel, validated computerized systems and archiving requirements. Within businesses, procedures govern performance of activities to ensure data integrity throughout its life cycle.
Our Manufacturing businesses produce FDA regulated endotoxin test kits at an FDA registered facility. We also manufacture sterility and microbial limits test kits used in FDA Regulated pharmaceutical applications, reagents, cell banks used in research and biopharmaceutical production, clinical trial vaccines and vaccine support products as well as an animal-free recombinant cascade reagent (rCR), Endosafe® Trillium®, which is an alternative to the natural LAL product. Additionally, several of our laboratories conduct biosafety and analytical testing such as identity, stability, sterility and potency and viral clearance testing in support of our clients’ manufacturing programs and to fulfill their validation requirements, as applicable.
Our comprehensive cell and gene therapy manufacturing services include Good Manufacturing Practices (GMP) production of cells from pre-clinical to commercial applications from a variety of starting materials. Many of these activities are subject to regulation and consequently require these businesses to be inspected by the FDA and other national and applicable state regulatory agencies under their respective cGMP regulations. These regulations require that we manufacture products or perform testing in a prescribed manner with respect to cGMP compliance, and maintain records of our manufacturing, testing and control activities. In addition, the specific activities of some of our businesses require us to hold specialized licenses and registrations for the manufacture, distribution and/or marketing of particular products globally.
Our Cell Solutions sites provide the starting material (leukopak) to customers that are typically in cell and gene therapy companies. Leukopaks are collected from eligible donors in compliance with applicable regulatory requirements. Donors consent using consent forms from an Institutional Review Board (IRB). Collections are performed under the supervision of licensed clinical staff and collections are managed in accordance with IRB-approved study protocols.
All of our GMP sites are subject to registration, licensing and regulation, as appropriate under international treaties and conventions, including national, regional and local laws relating to:
the surface and air transportation of chemicals, biological reagents and laboratory specimens;
the handling, use, storage and disposal of chemicals (including narcotics and psychotropic drugs), biological reagents, laboratory specimens, hazardous waste and radioactive materials;
the procurement, handling, use, storage and disposal of human cells, tissues and cellular and tissue-based products for research purposes;
the safety and health of employees and visitors to our facilities; and
protection of the environment and general public.

Global regulatory compliance programs are managed by a dedicated group responsible for regulatory affairs and compliance. Our compliance programs are also managed by global quality systems, such as vendor supplier programs, enterprise quality management systems and global computer system validation. Within each regulated business, we have established Quality Assurance Units (QAUs) responsible for risk based internal audit programs to manage regulatory requirements and client expectations. The QAUs operate independently from those individuals that direct and conduct studies, manufacturing or analytical testing. Our Data Integrity Compliance Program ensures that senior management and the QAU’s have proper oversight of our electronic records, inclusive of quality function reviews of our computerized system practices to ensure that appropriate record controls are in place and that a robust audit strategy confirms requirements for compliance.
While we expect that capital expenditures will be necessary to ensure that our existing sites remain in compliance with all applicable regulations, at this point we do not expect these expenditures to materially differ than our historical experience.
Intellectual Property
We develop and implement scientifically-driven products and procedures, including computer software, to maximize the quality and effectiveness of our offerings. Intellectual property rights, in the form of know-how, trade secrets, patents, trademarks, copyrights, and others are important to us and are valuable to our ability to provide significant benefits to our clients. Steps are taken to protect our intellectual property rights and include the execution of confidentiality agreements and securing registrations in relevant jurisdictions. In addition, we license technology from other companies when it enhances our product and services businesses. Licensing has recently become a larger company-wide initiative, particularly as we increase our focus on innovative technologies that further diversify and enhance our portfolio.
Corporate Governance
We are committed to operating our business with integrity and accountability. We strive to meet or exceed all of the corporate governance standards established by the NYSE, the SEC and the U.S. Federal government as implemented by the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and other applicable laws, rules and regulations. Nine of the eleven members of our Board of Directors are independent and have no significant financial, business or personal ties to us or management. Our Audit Committee, Compensation Committee, and Corporate Governance and Nominating Committee of our Board of Directors are each composed entirely of independent directors. The Board adheres to our Corporate Governance Guidelines and a Code of Business Conduct and Ethics that has been communicated to employees and posted on our website. We are diligent in complying with established accounting principles and are committed to providing financial information that is transparent, timely and accurate. We have a Related Person Transactions Policy designed to promote the timely identification of such transactions and to ensure we give appropriate consideration to any real or perceived conflicts in our commercial arrangements. We have an established global process through which employees, either directly or anonymously, can notify management (and the Audit Committee of the Board of Directors) of alleged accounting and auditing concerns or violations including fraud. Our internal Disclosure Committee meets regularly and operates pursuant to formal disclosure procedures and guidelines to help ensure that our public disclosures, including our periodic reports filed with the SEC, earnings releases and other written information that we disclose to the investment community are complete, accurate and timely. We continually monitor developments in the law and stock exchange regulations, as well as overall corporate governance trends and intend to adopt new procedures consistent with such developments to the extent applicable to and appropriate for our Company. Copies of our Corporate Governance Guidelines, Code of Business Conduct and Ethics and Related Person Transactions Policy are available on our website at http://ir.criver.com under the “Investor Relations - Corporate Governance” caption.

Increasing focus on environmental, social and governance matters may impact our business, financial results or stock price.
Risk Factors
Business and Operational Risks
We bear financial risk for contracts that may be terminated or reduced in scope, underpriced, subject to cost overruns or delays.
Many of our agreements, including those which underlie our strategic relationships with some of our more significant clients, allow for termination or reduction in scope with little or no notice. In addition, we sell our products and services to our competitors, and similarly they sell products and services to us. For instance, we have historically entered into, and currently are party to, contracts with certain of our competitors to distribute specialty research models in locations where our competitors may not have distribution capabilities.
Our counterparties (including our clients who are competitors) may elect to terminate their agreements with us for various reasons including: the invocation of force majeure clauses, or the legal doctrines of impossibility or impracticability, or other similar legal doctrines; the products being tested fail to satisfy safety requirements; unexpected or undesired study results; production problems resulting in shortages of the drug being tested; a client’s decision to forego or terminate a particular study; our competitors’ establishment of alternative distribution channels; dissatisfaction with our performance under the agreement; the loss of funding for the particular research study; or general convenience/counterparty preference. If a counterparty terminates a contract with us, we are typically entitled under the terms of the contract to receive revenue earned to date as well as certain other costs and, in some cases, termination fees; however, in many cases we are not entitled to any termination fees in the event of a termination. Cancellation of a large contract or proximate delay, cancellation or conclusion of multiple contracts could materially adversely affect our business and, therefore, may adversely affect our operating results.
Furthermore, many of our contracts provide for services on a fixed price or fee-for-service with a cap basis and, accordingly, we bear the financial risk if we initially underprice our contracts or otherwise overrun our cost estimates. Such underpricing or significant cost overruns could have an adverse effect on our business, results of operations, financial condition and cash flows.
Upgrading and integrating our business systems could result in implementation issues and business disruptions.
In recent years, we have been updating and consolidating platforms and automating processes in many parts of our business with a variety of systems, including in connection with the integration of acquired businesses. The expansion and ongoing implementation of operational systems may occur at a future date based on value to the business. In general, the process of planning and preparing for these types of integrated, wide-scale implementations is extremely complex and we are required to address a number of challenges, including information security assessment and remediation, regulatory requirements, data conversion, associated regulatory compliance, network and system cutover, user training, and integration with existing
19

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
processes or systems. As we build out IT infrastructure to support regulatory requirements for applications and data systems, we are doing so utilizing contemporary validation practices. As with all work conducted in our regulatory sites, these too are subject to government inspections. Incongruities in any of these areas could cause operational problems during implementation including inconsistent practices, delayed report and/or data shipments, missed sales, animal management/welfare issues, issues that require re-doing certain studies, personally identifiable information and data privacy issues, billing errors and accounting errors.
We have in the past experienced and in the future could experience unauthorized access into our information systems.
We operate large and complex information systems that contain significant amounts of client data. As a routine element of our business, we collect, analyze and retain substantial amounts of data pertaining to the non-clinical studies we conduct for our clients. Unauthorized third parties could attempt to gain entry to such information systems to steal data or disrupt the systems or for financial gain. Like other companies, we have on occasion experienced, and will continue to experience, threats and incursions to our data and systems, including malicious software and viruses, phishing, business email compromise and social engineering attacks or other cyber-attacks. The number and complexity of these threats continue to increase over time.
In March 2019, we detected evidence that an unauthorized third party, who we believe was well resourced and highly sophisticated, accessed certain of our information systems and copied data. We worked with a leading cyber security firm to assist in our investigation and coordinated with law enforcement authorities. Our investigation indicated that the affected information included client information. By the end of 2019, we disclosed that we had completed our remediation of the identified incident. As of the date of this filing, to our knowledge, we have not experienced an information security breach or material cybersecurity incident since that event. While we have implemented additional security safeguards since that event and continue to enhance existing safeguards, such efforts may not be successful, in which case we could suffer significant harm.
Further, we are at risk of being targeted, and we have in the past been victim to, business email compromise fraud, which results in payments being made to illegitimate bank accounts. Although these instances have not resulted in our incurring material losses, if similar instances occur in the future, we may incur such losses.
Our contracts with our clients typically contain provisions that require us to keep confidential the information generated from the studies we conduct. In the event the confidentiality of such information is compromised, whether by unauthorized access or other breaches, we could be exposed to significant harm, including termination of customer contracts, damage to our customer relationships, damage to our reputation and potential legal claims from customers, employees and other parties. In addition, we may face investigations by government regulators and agencies as a result of a breach.
For information regarding our processes and practices related to information and cybersecurity, please see Section 1C of this report, “Cybersecurity”.
If we are not successful in selecting and integrating the businesses and technologies we acquire or partner with, or in managing our current and future divestitures, our business may be adversely impacted.
During the last two decades, we have steadily expanded our business through numerous acquisitions and partnerships. However, businesses and technologies may not be available on terms and conditions we find acceptable. We risk spending time and money investigating and negotiating with potential acquisition or alliance partners, but not completing transactions.
Acquisitions and alliances involve numerous risks which may include:
difficulties in achieving business and financial success (due to unplanned events such as the long-term economic impact of the COVID-19 pandemic and ongoing geopolitical conflicts, such as between the Russian Federation and Ukraine, and between Israel and Hamas);
difficulties and expenses incurred in assimilating and integrating operations, services, products, information technology platforms, technologies or pre-existing relationships with our clients, distributors and suppliers;
challenges with developing and operating new businesses, including those that are materially different from our existing businesses, which may require the development or acquisition of new internal capabilities and expertise;
potential losses resulting from operational weaknesses or undiscovered liabilities of acquired companies that are not covered by the indemnifications we may obtain from sellers or any insurance we may acquire in connection with transactions;
loss of key employees;
the presence or absence of adequate internal controls and/or significant fraud in the financial systems of acquired companies;
diversion of management’s attention from other business concerns;
20

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
a more expansive regulatory environment;
dilution to earnings, or in the event of acquisitions made through the issuance of our common stock to the shareholders of the acquired company, dilution to the percentage of ownership of our existing shareholders;
differences in foreign business practices, customs and importation regulations, language and other cultural barriers in connection with the acquisition of foreign companies;
new technologies and products may be developed that cause businesses or assets we acquire to become less valuable; and
disagreements or disputes with prior owners of an acquired business, technology, service or product that may result in legal settlements, litigation expenses and diversion of our management’s attention.
If an acquired business, technology or an alliance does not meet our expectations, our results of operations may be adversely affected. Some of the same risks exist when we decide to sell a business, site, product line or service offering or decide to close a site. We continually evaluate the performance and strategic fit of our business to determine whether any divestitures are appropriate. Such divestitures could involve additional risks, other than those listed above, including: difficulties in the separation of operations, services, products, and personnel, the need to agree to retain or assume certain current or future liabilities in order to complete the divestitures, and write-offs, including those related to goodwill and other intangible assets and which could have an adverse effect on our results of operations and financial condition. In addition, we may encounter difficulty in finding buyers or alternative exit strategies at acceptable prices and terms, and in a timely manner. We may not be successful in managing these or any other significant risks that we encounter in divesting a business, site or product line or service offering and, as a result, we may not achieve some or all of the expected benefits of the divestitures.
Failure to execute our business strategy could adversely impact our growth and profitability.
Our strategy is to deliver a comprehensive and integrated portfolio of drug discovery and non-clinical development products, services and solutions to support our clients’ discovery and early-stage drug research, process development, scale up and manufacturing efforts, and enable them to bring new and improved therapies to market faster and more cost effectively. Separately, through our various Manufacturing segment businesses, we aim to be the premier provider of products and services that ensure our clients produce and release their products safely. If we are unable to successfully execute on this strategy, this could negatively impact our future results of operations and market capitalization.
Any decline or lower than expected growth in our served markets could diminish demand for our products and services, which would adversely affect our results of operations and financial condition. To address this issue, we typically pursue a number of strategies designed to improve our internal growth, including strengthening our presence in selected geographic markets through organic growth and strategic acquisitions and expanding our service offerings, including our expansion into the CDMO business. We may not be able to successfully implement these strategies, and these strategies may not result in the expected growth of our business.
Furthermore, our strategy assumes a certain degree of capital and capacity growth development. Factors such as insufficient capital, inflation, supply chain interruptions, inadequate forecasting, increases in construction material costs, or labor shortages could interfere with the successful execution of our strategy and our ability to timely build infrastructure to satisfy capacity needs and support business growth. For additional discussion of our business strategy, please see the section above entitled “Our Strategy.”
Our business is subject to risks relating to operating internationally, including changes in foreign currency exchange rates.
A significant part of our revenue is derived from operations outside the U.S. We expect that international revenue will continue to account for a significant percentage of our total revenue for the foreseeable future.
Changes in foreign currency exchange rates could materially adversely impact our results. Foreign currencies we receive for sales and in which we record expenses outside the U.S. could be subject to unfavorable exchange rates with the U.S. dollar, resulting in a reduction in the amount of revenue and cash flow (and an increase in the amount of expenses) that we recognize and causing fluctuations in reported financial results. We also carry foreign currency exposure associated with differences between where we conduct business. For example, certain contracts are frequently denominated in currencies other than the currency in which we incur expenses related to those contracts. Where expenses are incurred in currencies other than those in which contracts are priced, fluctuations in the relative value of those currencies could have a material adverse effect on our results of operations.
Our exposure to currency exchange rate fluctuations results from the currency translation exposure associated with the preparation of our consolidated financial statements, as well as from the exposure associated with transactions of our subsidiaries that are denominated in a currency other than the respective subsidiary’s functional currency. While our financial results are reported in U.S. Dollars, the financial statements of many of our subsidiaries outside the U.S. are prepared using the
21

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
local currency as the functional currency. During consolidation, these results are translated into U.S. Dollars by applying appropriate exchange rates. As a result, fluctuations in the exchange rate of the U.S. Dollar relative to the local currencies in which our foreign subsidiaries report could cause significant fluctuations in our reported results. Moreover, as exchange rates vary, revenue and other operating results may differ materially from our expectations. Adjustments resulting from financial statement translations are included as a separate component of shareholders’ equity.
Other risks associated with our international business include:
general economic and political conditions in the markets in which we operate;
potentially negative consequences from changes in U.S. and/or foreign laws, including changes that may bar us from engaging in business transactions with certain clients, and changes in tax laws, or interpretations and enforcement thereof, notably tax regulations issued and to-be-issued with respect to the potential adoption of global minimum taxation requirements and potential changes to existing tax law by the current U.S. Presidential administration and Congress;
ongoing uncertainties as a result of instability or changes in geopolitical conditions, including terrorist acts or military or political conflicts, such as those caused by the ongoing conflicts between Russia and Ukraine or Israel and Hamas (the potential escalation or geographic expansion of which could heighten other risks identified in this report);
exchange controls, adverse tax consequences and legal restrictions on the repatriation of funds into the U.S.;
difficulties and costs associated with staffing and managing foreign operations, including risks of work stoppages and/or strikes, as well as violations of local laws or anti-bribery laws such as the U.S. Foreign Corrupt Practices Act (FCPA), the U.K. Bribery Act and the OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions;
unexpected changes in regulatory requirements;
the difficulties of compliance with a wide variety of foreign laws and regulations;
unfavorable labor regulations in foreign jurisdictions;
longer accounts receivable cycles in certain foreign countries;
potentially reduced protection of our intellectual property rights in certain foreign countries; and
compliance with export controls, import requirements and other trade regulations, including those relating to certain products of which there is limited supply.
These risks, individually or in the aggregate, could have an adverse effect on our results of operations and financial condition. For example, as mentioned above, we are subject to compliance with the FCPA, which prohibits companies and their third-party intermediaries from offering or making improper payments to foreign government officials for the purpose of obtaining or retaining business. Likewise, we are also subject to other international anti-bribery laws such as the UK Bribery Act which prohibit companies and their third-party intermediaries from offering or making improper payments to commercial parties. While our employees and third-party intermediaries are required to comply with these laws, we cannot be sure that our internal policies and procedures will always protect us from violations of these laws despite our commitment to legal compliance and corporate ethics. The occurrence or allegation of these types of risks may adversely affect our business, performance, prospects, value, financial condition and results of operations.
Our operations might be affected by the occurrence of a natural disaster or other catastrophic event.
We depend on our customers continued demand and solvency at our facilities for the continued operation of our business. While we maintain disaster recovery plans, they might not adequately protect us. Despite any precautions we take for natural disasters or other catastrophic events, these events, including terrorist attack, a pandemic, epidemic or outbreak of a disease, hurricanes, tornadoes, fire, floods and ice and snow storms, could result in damage to and closure of our or our customers’ facilities or the infrastructure on which such facilities rely. Such disruptions could include significant delays in the shipments of our products, reduce our capacity to provide services, adversely impact unique manufacturing capabilities, result in our customers’ inability to pay for our products or services and, ultimately, result in the loss of revenue and clients. Although we carry business interruption insurance policies and typically have provisions in our contracts that protect us in certain events, our coverage might not be adequate to compensate us for all losses that may occur. Any natural disaster or catastrophic event affecting us or our customers could have a significant negative impact on our operations and financial performance.
Negative attention from special interest groups may impair our business.
The products and services that we provide our clients are essential to the drug discovery, development and manufacturing processes, and a significant amount are mandated by law. Notwithstanding, certain special interest groups categorically object

to the use of animals for valid research purposes. Historically, our core research model activities with rats, mice and other rodents have not been the subject of significant animal rights media attention. However, research activities involving animal models have been the subject of adverse attention, including shareholder proposals and attempts to disrupt carriers from transporting large research models and actions aimed at preventing expansion of operations . This has included periodic demonstrations near facilities operated by us and at our annual meetings, as well as shareholder proposals we received for some of our past Annual Meetings of Shareholders. Furthermore, the habitat of certain animals used for research purposes may be located in or near certain environmentally protected areas or conservation areas. Activities conducted by us or any of our agents within these areas may be legally challenged and result in similar negative attention and action from environmental protection activists, including advocacy for the expansion of environmental restrictions applicable to such areas. Any negative attention, threats, acts of vandalism or legal action directed against our animal research or procurement activities, or our third-party service providers, such as our airline carriers or suppliers, or that restrict our or their ability to access protected or conservation areas, could impair our ability to operate our business efficiently.
Industry Risk Factors
Several of our product and service offerings, including our non-human primate supply, are dependent on a limited source of supply that, when interrupted, adversely affects our business.
We depend on a limited international source of supply for certain products, such as large research models, including non-human primates. Disruptions to their continued supply from time to time arise from colony health problems (including as a result of the spread of diseases), export or import laws/restrictions or embargoes, tariffs, inflation, international trade regulations, foreign government or economic instability, severe weather conditions, increased competition among suppliers for models, disruptions to the air travel system, activist campaigns, commercial disputes, supplier insolvency, geopolitical disputes, or other ordinary course or unanticipated events. Any disruption of supply could materially harm our business if we cannot remove the disruption or are unable to secure an alternative or secondary supply source on comparable commercial terms.
As with other industry participants, certain of our activities rely on a sufficient supply of large research models, which has seen increasing demand as compared to supply in recent years due to a variety of factors. First, the surge of research relating to COVID-19 increased short-term demand. Second, China previously supplied a significant portion of certain critical large research models, which have been subject to geographic export restrictions applicable to many animal species since the beginning of the COVID-19 pandemic. And third, in concert with legal matters affecting the Cambodian supply of non-human primates, the non-human primate supply chain globally has recently experienced constriction. More broadly, in November 2022 the U.S. Department of Justice (DOJ) announced that a Cambodia supplier of non-human primates and two Cambodian officials had been criminally charged in connection with illegally importing non-human primates into the United States. While the Company was not named or referenced in the November 2022 proceedings, the Company shortly thereafter announced that Cambodia was the primary country of origin for non-human primates imports to Charles River, and that it had begun to operate under the expectation that for some time period supply of Cambodia-sourced non-human primates (which according to CDC statistics, account for approximately 60% of supply to the United States) would be difficult to obtain in the United States. Subsequent to the Company’s announcement, USFWS denied clearance to certain shipments of non-human primates the Company had received from Cambodia. And as noted in Item 3. “Legal Proceedings” in this Annual Report on Form 10-K, in February 2023 the Company was informed by the DOJ that in conjunction with the U.S. Fish and Wildlife Service (USFWS), they had commenced a grand jury investigation into the Company’s conduct regarding several shipments of non-human primates, which is occurring in parallel to a civil investigation being undertaken by the DOJ and USFWS. In connection with the civil investigation, the Company has voluntarily suspended planned future shipments of Cambodia non-human primates into the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported to the United States from Cambodia are purpose-bred. Accordingly, the Company believes that for some undetermined period of time it will not be able to import Cambodia-sourced non-human primates into the United States, and overall supply of non-human primates from Cambodia on a world-wide basis is more limited than previously.
While we continue to take steps to find alternative supply channels (and other global sources) and lock in supply (both for non-human primates and with respect to other limited supply products) with preferred sources through multi-year and/or minimum commitment contracts as well as through acquisitions of suppliers, there are limited sources and such mitigating efforts may not prove successful at ensuring a steady and timely supply or may require (and in the past have required) us to pay significantly higher prices for such products during periods of global shortage or restrictions on the importation or the transportation of models products. Limited global supply or regional restrictions on transportation for certain products may require us to source products from non-preferred vendors, which may not be successful. In addition, reductions in global air transportation routes may result in sourcing alternative transportation at an increased cost. Finally, we may be unable to obtain supply due to governmental restrictions or limitations, including (as noted above) non-human primates. An inability to obtain a sufficient and timely supply of critical products could adversely affect our business, financial results and results of operations.

Portions of our Cell Solutions business depends on the availability of appropriate donors. Regulations intended to control infectious disease or requirements in cell therapy manufacturing processes could also result in a decreased pool of potential donors or integrity of inventory. Due to any pandemic, epidemic or outbreak in one or more regions in which our Cell Solutions business operates, the portion of the donor pool that typically donates may be unable, or unwilling to donate, thereby significantly reducing the availability of research products upon which we rely. In addition, healthcare concerns among the public may result in a decline in donations. If donor participation declines, we may not be able to reduce costs sufficiently to maintain profitability of the Cell Solutions business.
Our CDMO services establish us as a premier scientific partner for cell and gene therapy development, testing, and manufacturing; enable us to provide clients with an integrated solution from basic research and discovery through cGMP production; enable us to drive efficiency and accelerate clients’ speed-to-market by integrating manufacturing and the required testing; and enable our clients to seamlessly conduct analytical testing, process development, and manufacturing for advanced modalities with the same scientific partner. Furthermore, our CDMO operations require various raw materials supplied primarily by third parties. We or our customers specify the raw materials and other items required to manufacture the applicable product and, in some cases, the customers specify the suppliers from whom we must purchase these raw materials. In certain instances, the raw materials and other items may only be supplied by a limited number of suppliers or in limited quantities. If third-party suppliers do not supply raw materials or other items on a timely basis, it may cause a manufacturing run to be delayed or canceled which could materially adversely affect our results of operations and financial condition.
Furthermore, in general, third-party suppliers may fail to provide us with raw materials and other items that meet the qualifications and specifications required by us or our customers. If third-party suppliers are not able to provide us with raw materials that meet our or our customers’ specifications on a timely basis, we may be unable to manufacture the product for our clients or it could prevent us from delivering products to our customers within required time frames. Any such delay in delivering products to our clients may create liability for us to our customers for breach of contract or cause us to experience order cancellations and loss of customers. In the event that we manufacture products with components or raw materials that do not meet our qualifications and specifications or those of our customers or governmental or regulatory authorities, we may become subject to product liability claims caused by defective raw materials or components from a third-party supplier or from a customer.
Demand volatility and risk of credit losses from clients may adversely affect our business.
Our business could be adversely affected by any significant decrease in drug R&D expenditures by pharmaceutical and biotechnology companies, as well as by academic institutions, government laboratories or private foundations. Similarly, economic factors and industry trends that affect our clients in these industries also affect their R&D budgets and, consequentially, our business as well.
Our clients include researchers at pharmaceutical and biotechnology companies. Our ability to continue to grow and win new business is dependent in large part upon the ability and willingness of the pharmaceutical and biotechnology industries to continue to spend on molecules in the non-clinical phases of R&D (and in particular discovery and safety assessment) and to outsource the products and services we provide. Furthermore, our clients (particularly larger biopharmaceutical companies) continue to search for ways to maximize the return on their investments with a focus on lowering R&D costs per drug candidate. Fluctuations in the expenditure amounts in each phase of the R&D budgets of these researchers and their organizations could have a significant effect on the demand for our products and services. R&D budgets fluctuate due to changes in available resources, mergers of pharmaceutical and biotechnology companies, spending priorities (including available resources of our biotechnology clients, particularly those that are cash-negative, who may be highly focused on rationing their liquid assets in a challenging funding environment), general economic conditions, institutional budgetary policies and the impact of government regulations, including potential drug pricing legislation. Available funding for biotechnology clients in particular may be affected by the capital markets, investment objectives of venture capital investors and priorities of biopharmaceutical industry sponsors.
Additionally, our business is exposed to the risk of credit losses, which arises from our extension of credit to clients. The collectability of accounts receivable may be adversely affected by various factors, including economic downturns, changes in clients’ financial conditions, and industry-specific challenges. A deterioration in the creditworthiness of our clients could result in the need to establish or increase our allowance for credit losses. We regularly assess the creditworthiness of our clients, establish credit limits, and monitor payment patterns. However, our ability to manage credit risk and maintain an adequate allowance for credit losses may be impacted by factors beyond our control, such as unforeseen economic conditions or significant shifts in client payment behavior. Additionally, changes in global or regional economic conditions may affect the overall credit environment and impact our customers' ability to fulfill their payment obligations.
For additional discussion of the factors that we believe have recently been influencing R&D budgets at our clients, please see the sections entitled “Our Strategy” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included elsewhere in this Form 10-K.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Additionally, we have business that depends on our supply of large research models to clients. Sudden or unexpected changes in demand, market conditions, or the regulatory environment for these models could have an adverse impact on our profitability. Increasing demand could harm relationships with customers if we are unable to alter production capacity, or purchase products from other suppliers, to fill orders adequately. Decreased demand could result in inventory surpluses, which could also significantly impact our results and operations. In particular, if the price of non-human primates increases significantly, or if we are unable to transport the non-human primates in our possession to our clients because of governmental restrictions or limitations, our business may be materially adversely affected. In addition, overall supply constraints with respect to large research models has led to an extremely dynamic pricing environment for non-human primates, which has, and could continue to, make it difficult to predict results, lead to reduced volumes, and require us to adjust operations.
Furthermore, our Cell Solutions operations are structured to produce research materials, such as blood products based on clients’ existing demand, and perceived potential changes in demand, for these products. Sudden or unexpected changes in demand for these products could have an adverse impact on our profitability. Increasing demand could harm relationships with clients if we are unable to alter production capacity, or purchase products from other suppliers, to fill orders adequately. This could result in a decrease in overall revenue and profits. Lack of access to sufficient capital, or lack of adequate time to properly (or the failure to adequately) respond to changes in demand, could result in declining revenue and profits, as clients transfer to other suppliers.
We also operate businesses which depend upon the regulatory approval of the products they manufactures for their contract development and manufacturing organization (CDMO) clients. As such, if these clients experience a delay in, or failure to receive, approval for any of their product candidates or fail to maintain regulatory approval of their products that we develop or manufacture, our revenue and profitability could be materially adversely affected. Additionally, if the FDA or a comparable foreign regulatory authority does not approve of our facilities for the manufacture of a client product, observes significant deficiencies or violations at its facilities or withdraws such approval in the future, our clients may choose to identify alternative manufacturing facilities and/or relationships, which could significantly impact our CDMO capacity and capabilities and results of operations therefrom.
A reduction or delay in government funding of R&D may adversely affect our business.
A portion of revenue, predominantly in our RMS segment, is derived from clients at academic institutions and research laboratories whose funding is partially dependent on both the level and timing of funding from government sources such as the U.S. National Institutes of Health (NIH) and similar domestic and international agencies, which can be difficult to forecast. We also sell directly to the NIH and these other agencies. Government funding of R&D is subject to the political process, which is inherently fluid and unpredictable. Our revenue may be adversely affected if our clients delay purchases as a result of uncertainties surrounding the approval of government budget proposals, included reduced allocations to government agencies that fund R&D activities. Government proposals to reduce or eliminate budgetary deficits have sometimes included reduced allocations to the NIH and other government agencies that fund R&D activities, or NIH funding may not be directed towards projects and studies that require the use of our products and services, both of which could adversely affect our business and our financial results.
Changes in government regulation or in practices relating to the pharmaceutical or biotechnology industries, including potential healthcare reform, could decrease the need for the services we provide.
Governmental agencies throughout the world strictly regulate the drug development process. Our business involves helping our customers navigate these regulatory processes. Accordingly, many regulations, and often new regulations, are expected to result in higher regulatory standards and often additional revenues for companies that service these industries. However, some changes in regulations, such as a relaxation in regulatory requirements or the introduction of streamlined or expedited drug approval procedures, or an increase in regulatory requirements that we have difficulty satisfying or that make our services less competitive, could eliminate or substantially reduce the demand for our services.
For example, in December 2022, the FDA Modernization Act 2.0 was passed, which requires the FDA to develop and implement a strategy to reduce the use of animals in testing while maintaining the safety and effectiveness of medical products and to explore the use of non-animal alternatives to animal testing. Eliminating the use of animals in research may have material adverse effects on our business, results of operations, or financial condition. While there have been significant advancements in the development of alternative methods, the complete elimination of animals in research will be a gradual process that may take many years to achieve. While we are committed to working with the industry to support development and to provide the best translational models to supplement or replace traditional models as part of our 4Rs initiative, the use of animals in research is highly regulated and proposed changes to current regulations will need to be carefully evaluated to ensure that they do not compromise the safety and efficacy of new drugs and medical treatments.
Although we believe we are currently in compliance in all material respects with applicable national, regional and local laws, as well as other accepted guidance used by oversight bodies (including the USDA, the standards set by the International Air
25

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Transport Association, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, USFWS, The Centers for Disease Control, the Department of Transportation, the Department of State, the office of Laboratory Animal Welfare of NIH, the Drug Enforcement Agency, as well as numerous other oversight agencies in the jurisdictions in which we operate), failure to comply could subject us to denial of the right to conduct business, fines, criminal penalties and other enforcement actions. For additional discussion of the factors specifically affecting our non-human primates including related oversight trade compliance agencies, please see the sections entitled “Item 1A. Risk Factors – Industry Risk Factors - Several of our product and service offerings, including our non-human primate supply, are dependent on a limited source of supply that, when interrupted, adversely affects our business”, and “Item 3. Legal Proceedings” included elsewhere in this Form 10-K. In addition, if regulatory authorities were to mandate a significant reduction in safety assessment procedures that utilize research animals (as has been advocated by certain groups), certain segments of our business could be materially adversely affected.
Implementation of healthcare reform legislation may have certain benefits, but also may contain costs that could limit the profits that can be made from the development of new drugs. This could adversely affect R&D expenditures by pharmaceutical and biotechnology companies, which could in turn decrease the business opportunities available to us both in the U.S. and abroad. In addition, new laws or regulations may create a risk of liability, increase our costs or limit our service offerings. Furthermore, if health insurers were to change their practices with respect to reimbursements for pharmaceutical products, our clients may spend less or reduce their growth in spending on R&D.
While it is not possible to predict whether and when any such changes will occur, changes at the local, state or federal level, or in laws and regulations in effect in foreign jurisdictions in which we operate or have business relationships, may significantly impact our domestic and foreign businesses and/or those of our clients. Furthermore, modifications to international trade policy, public company reporting requirements, environmental regulation and antitrust enforcement may have a materially adverse impact on us, our suppliers or our clients.
Our Biologics Solutions business, financial condition and results of operations may be adversely affected if the products we manufacture and/or test for our customers do not gain market acceptance.
If the products we manufacture for our customers do not gain market acceptance or production volumes of key products that we manufacture for our customers decline, the financial condition and results of our operations may be adversely affected. For our CDMO services, we will depend on, and have no control over, market acceptance for the products that we will manufacture for our customers. Consumer demand for these products could be adversely affected by, among other things, delays in securing regulatory approvals, the emergence of competing or alternative products, including generic drugs, the emergence of new safety data for such products, the loss of patent and other intellectual property rights protection, reductions in private and government payment product subsidies or changing product marketing strategies.
CDMO services are highly complex and failure to provide quality and timely services to our CDMO customers, could adversely impact our business.
The CDMO services we offer can be highly complex, due in part to strict regulatory requirements and the inherent complexity of the services provided. A failure of our quality control systems in our facilities could cause problems in connection with facility operations for a variety of reasons, including equipment malfunction, viral contamination, failure to follow specific manufacturing instructions, protocols and standard operating procedures, problems with raw materials or environmental factors. Such issues could affect production of a single manufacturing run or manufacturing campaigns, requiring the destruction of products, or could halt manufacturing operations altogether. In addition, any failure to meet required quality standards may result in our failure to timely deliver products to our customers which, in turn, could damage our reputation for quality and service. Any such incident could, among other things, lead to increased costs, lost revenue, reimbursement to customers for lost drug substances, damage to and possibly termination of customer relationships, time and expense spent investigating and remediating the cause and, depending on the cause, similar losses with respect to other manufacturing runs. In addition, such issues could subject us to litigation, the cost of which could be significant.
Contaminations in our animal populations can damage our inventory, harm our reputation for contaminant-free production, result in decreased sales and cause us to incur additional costs.
Both small and large animal research models must be free of certain infectious agents, such as certain viruses, parasites, and bacteria, because the presence of these contaminants can distort or compromise the quality of research results and/or could adversely impact human or animal health. The presence of these infectious agents in our animal production facilities and certain service operations could impact the quality of our contaminant-free research model as well as our animal services businesses, including GEMS, harm our reputation for contaminant-free production and result in decreased sales. There also exists a risk that contaminations from models that we produce may affect our client’s facilities, with similar impact to them for which we could be liable for damages. In some cases, we may produce or import animals carrying infectious agents capable of causing disease in humans; and in the case of such a contamination or undiagnosed infection, there could be a possible risk of human exposure and infection and liability for damages to infected persons.
26

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
When considering our large research models, while some of these models are owned by us and maintained at our facilities, others are reserved for us and maintained at sites operated by the original provider. Accordingly, risk of contamination may be outside of our control, and we depend on the practices and protocols of third parties to ensure a contamination-free environment. A contamination may require extended CDC or CFIA quarantine with subsequent reduced sales as a result of lost client orders, as well as the potential for complete inventory loss and disinfection of the affected quarantine rooms. Furthermore, while we often negotiate for contractual risk indemnification, the third party may refuse to fulfill its indemnification obligation or may be unable to as a result of insolvency or other impediments.
Contaminations are unanticipated and difficult to predict and could adversely impact our financial results. If they occur, contaminations typically require cleaning up, renovating, disinfecting, retesting and restarting production or services. Such contaminations result in inventory loss, clean-up and start-up costs, and reduced sales as a result of lost client orders and potentially credits for prior shipments. In addition to microbiological contaminations, the potential for genetic contaminations also exists and may require us to restart the applicable animal colonies, and would result in inventory loss, additional start-up costs and possibly reduced sales. Contaminations also expose us to risks that clients will request compensation for damages in excess of our contractual indemnification requirements.
Further, many of our operations are comprised of complex mechanical systems that are subject to periodic failure, including aging fatigue. Such failures are unpredictable, and while we have made significant capital expenditures designed to create redundancy within these mechanical systems, strengthen our biosecurity, improve our operating procedures to protect against such contaminations, and replace impaired systems and equipment in advance of such events, failures and/or contaminations may still occur.
The outsourcing trend in non-clinical (discovery and safety assessment) stages of drug discovery and development may decrease, which could impair our growth.
Over the past decade, pharmaceutical and biotechnology companies have generally increased their outsourcing of non-clinical research support activities, such as discovery and safety assessment. While many industry analysts expect the outsourcing trend to continue to increase for the next several years (although with different growth rates for different phases of drug discovery and development), decreases in such outsourcing may result in a diminished growth rate in the sales of any one or more of our service lines and may adversely affect our financial condition and results of operations. For additional discussion of the factors that we believe have recently influenced outsourcing demand from our clients, please see the section entitled “Our Strategy” above.
The industries in which we operate are highly competitive.
The industries in which we operate are highly competitive. We compete for business with other non-clinical drug development partners and blood product and therapeutic services companies, other CDMOs, as well as internal discovery and development departments within our larger clients, who may have greater resources than ours. We also compete with universities and teaching hospitals for outsourced services. We compete on a variety of factors, including:
reputation for on-time quality performance;
reputation for regulatory compliance;
reputation for responsive client service and support;
expertise and experience in multiple specialized areas;
scope and breadth of service and product offerings across the drug discovery and development spectrum;
scope and breadth of service and product offerings across the manufacturing support spectrum;
ability to provide flexible and customized solutions to support our clients’ drug discovery, non-clinical development, and manufacturing support needs;
broad geographic availability (with consistent quality);
price/value, spend and flexibility;
technological and scientific expertise and efficient drug development processes;
quality of facilities;
financial stability;
size;
ability to acquire, process, analyze and report data in an accurate manner;
27

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
ability to place orders through eCommerce channels; and
accessibility of client data through secure portals.
If we do not compete successfully, our business will suffer. Increased competition might lead to price and other concessions that could adversely affect our operating results. The drug discovery and development services industry has continued to see a trend towards consolidation, particularly among the biotechnology companies, which are targets for each other and for large pharmaceutical companies. If this trend continues, it is likely to produce more competition among the larger companies, with respect to both clients and acquisition candidates. In addition, small, specialized entities considering entering the industries will continue to find lower barriers to entry, and private equity firms may determine that there are opportunities to acquire and consolidate these companies, thus further increasing possible competition. Our competition in the CDMO market includes full-service contract manufacturers and large pharmaceutical companies offering third-party manufacturing services to fill their excess capacity. Also, large pharmaceutical companies have been seeking to divest portions of their manufacturing capacity, and any such divested businesses may compete with us in the future. Furthermore, many of our CDMO competitors may have substantially greater financial, marketing, technical or other resources than we do. Moreover, additional competition may emerge, particularly in lower-cost jurisdictions such as India and China, which could, among other things, result in a decrease in the fees paid for our services, which may adversely affect our results of operations and financial condition.
More generally, our competitors or others might develop technologies, services or products that are more effective or commercially attractive than our current or future technologies, services or products, or that render our technologies, services or products less competitive or obsolete. If competitors introduce superior technologies, services or products and we cannot make enhancements to ours to remain competitive, our competitive position, and in turn our business, revenue and financial condition, would be materially and adversely affected. In the aggregate, these competitive pressures may affect the attractiveness of our technologies, services or products and could adversely affect our financial results.
New technologies may be developed, validated and increasingly used in biomedical research, which could reduce demand for some of our products and services.
The scientific community continues to develop cell-based and new alternative model methods (NAMs), which do not involve working with animals models and are designed to increase the translation from findings in early-stage discovery and pre-clinical studies to human studies, and vice-versa. As these methods continue to advance, they may supplement, and in some cases possibly replace or supplant methodologies that are currently in use, such as the use of traditional living animals in biomedical research. In addition, technological improvements, such as imaging and other translational biomarker technologies, could impact demand for animal research models. Further, manufacturers, including Charles River, have recently introduced recombinant versions of LAL, which has been historically derived from live animals. It is our strategy to explore new technologies to refine and potentially reduce the use of animal models and animal derived products as new in vitro and in silico methods become available and synthetically-manufactured products become validated with sufficient data to ensure public safety. For information regarding our efforts to support development and to provide the best translational models to supplement or replace traditional models, see “Our Strategy” included elsewhere in this Form 10-K. However, we may not be able to develop new products, inputs or processes effectively or in a timely manner to replace any lost sales. Lastly, other companies or entities may develop research models, inputs or processes with characteristics different from those that we produce, and that may be viewed as more desirable by some of our clients.
We may not be able to successfully develop and market new services and products.
We continue to seek opportunities to develop and market new services and products that complement or expand our existing business or service offerings. We believe our ability to innovate through internal research and development efforts and license or acquire new technologies from third parties are both critical to our ability to continue to meet the needs of our clients. Our ability to gain access to such technologies depends, in part, on our ability to convince innovators that we can successfully develop and commercialize their inventions. We cannot guarantee that we will be able to identify new technologies of interest to our clients. Even if we are able to identify these opportunities, negotiating license agreements on commercially acceptable terms may prove difficult. In addition, our ongoing internal research and development efforts may not always yield offerings that meet client demand. If we are unable to develop new services and products and/or create demand for those newly developed services and products, our future business, results of operations, financial condition and cash flows could be adversely affected.
Costs increasing more rapidly than market prices in certain of our businesses could reduce profitability.
The cost of collecting, processing and testing products has risen significantly in recent years and will likely continue to increase given stringency of demands on raw materials. These cost increases are related to new and improved testing procedures, increased regulatory requirements, and higher staff and supply costs, including labor inflation. Competition and fixed price contracts may limit our ability to maintain existing operating margins. Some competitors have greater resources than us to
28

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
sustain periods of marginally profitable or unprofitable sales. Costs increasing more rapidly than market prices may reduce profitability and may have a material adverse impact on our business and results of operations.
Legal and Regulatory Risk Factors
Any failure by us to comply with applicable regulations and related guidance could harm our reputation and operating results, and compliance with new regulations and guidance may result in additional costs.
Any failure on our part to comply with applicable regulations could result in the termination of ongoing research or the disqualification of data for submission on behalf of our clients to regulatory authorities. This could harm our reputation, our prospects for future work and our operating results. For example, the issuance of a notice of objectionable observations or a warning letter from the FDA based on a finding of a material violation affecting data integrity by us for GLP or cGMP requirements that are not addressed to the regulatory monitoring authorities’ satisfaction could materially and adversely affect us. If our operations are found to violate any applicable law or other governmental regulations, we might be subject to civil and criminal penalties, damages and fines or the temporary closure of our facilities. Any action against us for violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and damage our reputation.
Where applicable, our clients expect us to timely deliver their nonclinical data compliant with the FDA’s SEND (Standardization for Exchange of Nonclinical Data) standards. Notwithstanding, some of these standards require additional operating and capital expenses that will impact not only us and our industry competitors, but clients in the biomedical research community. Non-compliance with any of these expectations could lead to official action by a government authority, damage to our reputation and a potential loss of business.
In addition, regulations and guidance worldwide concerning the production and use of research animals for research purposes continue to evolve. Similarly, guidance has been and continues to be developed for other areas that impact the biomedical research community on both a national and international basis including transportation, mandated contingency planning, euthanasia guidance, import and export requirements of biological materials, health monitoring requirements and the use of disinfectants.
Our Cell Solutions business is subject to complex regulation by federal, state and local governments in the U.S. This business requires us to obtain many licenses, permits, authorizations, accreditations, approvals, and certificates to fully comply with appropriate regulations in every jurisdiction in which we operate and sell. Federal, state and local regulations do change, requiring prompt adoption to remain in a constant state of compliance. Changes in the regulations could require us to alter how we operate our business, potentially resulting in a significantly increased cost of compliance.
Our donor collection centers are registered with the FDA and the FDA periodically conducts inspections of those facilities and operations. At the conclusion of each inspection, the FDA provides us with a list of objectionable conditions and practices observed during the inspection that could result in additional enforcement actions. Failure to comply with the regulations enforced by the FDA could result in sanctions and/or remedies and have a material adverse effect on us.
We are required to comply with stringent, complex and evolving laws, rules, regulations and standards in many jurisdictions, as well as contractual obligations, relating to data privacy and security. Any actual or perceived failure to comply with these requirements could have a material adverse effect on our business.
We are required to comply with stringent, complex and frequently evolving laws, rules, regulations and standards in many jurisdictions, as well as contractual obligations, relating to data privacy and security. Ensuring that our collection, use, transfer, storage and other processing of personal information complies with such requirements can increase operating costs, impact the development of new products or services, and reduce operational efficiency.
Internationally, virtually every jurisdiction in which we operate has established its own data privacy and security legal framework with which we must comply. For example, we are required to comply with the European Union (EU) General Data Protection Regulation (GDPR), which became effective on May 25, 2018. The EU GDPR imposes stringent obligations regarding the collection, control, use, sharing, disclosure and other processing of personal data of individuals within the EU and European Economic Area (EEA). EU member states may also impose additional requirements in relation to personal data through their national implementing legislation.
The EU GDPR also imposes specific restrictions on the transfer of personal data to countries outside of the EU and EEA, including the use of appropriate safeguards to enable such transfers, such as Standard Contractual Clauses (SCCs) and the EU-US Data Privacy Framework (DPF). The EU-US DPF was adopted in July 2023 and provides US-based organizations who self-certify with a reliable mechanism for personal data transfers from the EU, United Kingdom, and Switzerland. Although these mechanisms are currently valid for purposes of transferring personal data, they could be subject to legal challenges and there is no assurance that we could satisfy or rely on these measures to lawfully transfer personal data. If we are otherwise unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner in which we
29

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
provide our services, the geographical location or segregation of our relevant systems and operations, and could adversely affect our financial results. While we have implemented controls and procedures to comply with the requirements of the EU GDPR, such procedures and controls may not be effective in ensuring compliance or preventing unauthorized transfers of personal data. Additionally, we are subject to the privacy and data protection laws of the UK, including the UK Data Protection Act of 2018 (UK GDPR). Similar to the EU GDPR, the UK GDPR imposes restrictions on the processing of personal data, as well as transfers of personal data from the UK to other countries. Failure to comply with the EU and/or the UK GDPR can result in significant fines and other liability.
Moreover, China adopted the Personal Information Protection Law (PIPL) and Data Security Law (DSL) in 2021, which promulgated national privacy and security requirements relating to the collection, processing, transfer and security of personal information in or from China. Violations of the PIPL or DSL could result in fines and penalties, suspension of data transfers, cancellation of business authorizations, personal liability for responsible company officers, as well as criminal and civil liability. In the event that the PIPL requires us to store data in China, or limits our ability to transfer data across borders, we may experience increased costs and business inefficiencies. Fines, corrective actions, or other penalties asserted due to alleged noncompliance may impose additional financial or operational costs, limit our ability to attract and retain local talent, or limit our ability to do business in China.
In the US, there are numerous federal and state data privacy and security laws, rules, and regulations governing the collection, use, disclosure, retention, security, transfer, storage and other processing of personal information, including federal and state data privacy laws, data breach notification laws, and data disposal laws. For example, at the federal level, we are subject the regulations of the Federal Trade Commission, which has the authority to regulate and enforce against unfair or deceptive acts or practices in or affecting commerce, including acts and practices with respect to data privacy and security. If our public statements about our use, collection, disclosure and other processing of personal information are alleged to be deceptive, unfair or misrepresentative of our actual practices, we may be subject to potential government or legal investigation or action. If we are found to have violated applicable laws or regulations, we may also be subject to penalties, fines, damages, injunctions or other outcomes that may adversely affect our operations and financial results. The United States Congress also has considered, and may in the future consider, various proposals from time to time for comprehensive federal data privacy legislation to which we may become subject if passed and which may adversely affect our operations and financial results.
At the state level, we are subject to laws and regulations like the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA). The CCPA and CPRA create transparency requirements for companies, grant California residents various rights with regard to their personal information, and impose additional data protection obligations on companies doing business in California. Failure to comply with the CCPA and CPRA may result in, among other things, significant civil penalties and injunctive relief, or potential statutory or actual damages. The CCPA and CPRA also provide a private right of action for data breaches that result in the loss of personal information. The CCPA and CPRA may impact our business activities and require compliance costs that adversely affect business, operating results, prospects and financial condition. These state statutes, and other similar state or federal laws that may be enacted in the future may require us to modify our data processing practices and policies, incur substantial compliance-related costs and expenses, and otherwise suffer adverse impacts on our business.
Additionally, while collecting research products from donors, we may collect, use, disclose, maintain and transmit donor information in ways that will be subject to many of the numerous state, federal and international laws and regulations governing the collection, use, disclosure, storage, transmission or confidentiality of patient-identifiable health information.
We have made changes to, and investments in, our business practices and will continue to monitor developments and make appropriate changes to help attain compliance with these evolving and complex laws, rules, regulations and standards. Any actual or perceived failure to comply with any such laws, rules, regulations, standards or contractual obligations could subject us to denial of the right to conduct business, significant fines, civil or criminal penalties, costly litigation (including class actions), government investigation or inquiries, enforcement actions, claims, proceedings, judgements, awards, penalties, sanctions or other adverse impacts that could have a material adverse effect on our business.
Failure to comply with U.S., state, local or international environmental, health and safety laws and regulations, including regulations issued by the Occupational Safety and Health Administration, Environmental Protection Agency, Nuclear Regulatory Agency and Department of Transportation, could result in fines and penalties and loss of licensure, and have a material adverse effect upon the Company’s business.
We are subject to licensing and regulation under laws and regulations relating to the protection of the environment and human health and safety, including laws and regulations relating to the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials, as well as regulations relating to the safety and health of laboratory employees and protecting employees from the spread of COVID-19. Failure to comply with these laws and regulations could subject us to denial of the right to conduct business, fines, criminal penalties and/or other enforcement actions that could have a material adverse effect on our business. Other environmental laws may have similar consequences to us or our supplier, or
30

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
result in liability to us. In addition, compliance with future legislation could impose additional requirements on us that may be costly.
Changes in U.S. and International Tax Law, results of tax audits, or material changes in our stock price could have a material adverse impact on our effective tax rate and financial results.
As a global company, we are subject to taxation in numerous countries, states, and other jurisdictions. Changes to governmental laws and regulations, or their interpretations, including the adoption of global minimum taxation requirements and potential changes to existing tax law by the current U.S. Presidential administration and Congress, could impact our profits, effective tax rate and cash flows.
We receive substantial tax credits and incentives in Canada, from both the Canadian federal and Quebec governments, China, France, the U.K., and the U.S. Any reduction in the availability or amount of these tax credits and incentives or outcomes of tax controversies associated with these credits, could have a material adverse effect on our profits, cash flows and effective tax rate. Additionally, we are subject to regular audits with respect to various tax returns and processes in the jurisdictions in which we operate. Errors or omissions in tax returns, process failures, increase to tax rates or differences in interpretation of tax laws by tax authorities may lead to litigation, payments of additional taxes, penalties, and interest.
We are subject to regular review and audit by both domestic and foreign tax authorities. As a result, we have received, and may in the future receive, assessments in multiple jurisdictions, on various tax-related assertions. Any adverse outcome of such a review or audit could harm our financial condition and operating results, require adverse changes to our business practices, or subject us to additional litigation and regulatory inquiries. In addition, the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment and often involves uncertainty. Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may affect our financial results in the period or periods for which such determination is made.
Our tax expense and liabilities are affected by certain factors, such as changes in our business operations, acquisitions, investments, entry into new businesses and geographies, intercompany transactions, changes in foreign currency exchange rates, changes in our stock price, changes to our forecasts of income and loss and the mix of jurisdictions to which they relate, and changes in our tax assets and liabilities and their valuation.
Non-clinical contract research services create a risk of liability.
As a global drug development partner, we face a range of potential liabilities, which may include:
risks associated with errors or omissions in reporting of study detail in non-clinical studies that may lead to inaccurate reports, which may undermine the usefulness of a study or data from the study, or which may potentially advance studies absent the necessary support or inhibit studies from proceeding to the next level of testing;
risks associated with our possible failure to properly care for our clients’ property, such as research models and samples, study compounds, records, work in progress, other archived materials or goods and materials in transit, while in our possession;
risks that models in our breeding facilities or in facilities that we manage may be infected with diseases that may be harmful and even lethal to them or humans, despite preventive measures for the quarantine and handling of imported animals;
risks that we may have errors and omissions and/or product liabilities related to our products designed to conduct lot release testing of medical devices, injectable drugs, food, beverages, and home and beauty products (primarily through our Microbial Solutions business), or in the testing of biologics and other services performed by our Biologics Solutions business, which could result in us or our clients failing to identify unsafe or contaminated materials;
risk of transmitting dangerous infectious diseases, as a result of the failure of our screening and testing processes, or new pathogens that may be undetected by such processes; and
recent acquisitions have expanded our business into the CDMO market, which entails additional risks of liability, including potential product liability claims, errors and omissions claims in connection with our services and potential liability under indemnification agreements between us and our officers and directors.
While we attempt to mitigate these risks through a variety of methods, it is impossible to completely eradicate such risks. In our RMS business, we mitigate these risks to the best of our abilities through our regimen of animal testing, quarantine procedures and veterinary staff vigilance, through which we seek to control the exposure of animal related disease or infections. In our Cell Solutions, DSA, and Manufacturing businesses, we attempt to reduce these risks through the negotiation of contractual risk transfer provisions, such as indemnification provisions, limitations of liability, and client insurance requirements.
31

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Contractual risk transfer indemnifications generally do not protect us against liability arising from certain of our own actions, such as negligence or misconduct. We could be materially and adversely affected if we are required to pay damages or bear the costs of defending any claim that is outside any contractual indemnification provision, or if a party does not fulfill its indemnification obligations or the damage is beyond the scope or level of insurance coverage. We also often contractually indemnify our clients (subject to a limitation of liability), similar to the way they indemnify us, and we may be materially adversely affected if we have to fulfill our indemnity obligations. Furthermore, either we or a party required to indemnify us may not be able to maintain such insurance coverage (either at all or on terms acceptable to us).
The failure to successfully obtain, maintain and enforce intellectual property rights and defend against assertions of third-parties to intellectual property rights could adversely affect us.
Many of our services, products and processes rely on intellectual property. In some cases, that intellectual property is owned by another party and licensed to us, sometimes exclusively. To protect our intellectual property rights, we primarily rely upon trade secret, patent, and copyright law, as well as contractual provisions relating to intellectual property ownership and control and confidentiality. Laws relating to intellectual property rights and contracts vary from country to country and are subject to change at any time. In addition, the agreements upon which we rely to protect our intellectual property might be breached, or might not be fully enforceable. Our intellectual property rights might not prevent our competitors from independently developing intellectual property that is similar to or duplicative of ours. Also, enforcement of our intellectual property rights may also require substantial investments of time, money, and oversight, and may not result in success. If we are unable to secure and maintain our intellectual property rights, or if we are unable to prevent misappropriation or infringement, our business could be adversely affected.
Furthermore, we respect third-party intellectual property rights, and make efforts to avoid violating valid and enforceable intellectual property rights, and seek to procure and pay for licenses from the holders of intellectual property rights that we seek to use. In some cases, we are asked to utilize components and processes that are provided to us by our clients.
Customers of our CDMO business, for example, may utilize intellectual property for the production of their products, the manufacture of which has been contracted to us. Failure by us and/or our customers to secure and maintain rights to third-party intellectual property rights could have a material adverse effect, including reduced revenue as a result in a delay or cancellation of the manufacture of products and involvement in judicial and administrative proceedings in which we are named as a party.
Further, the drug discovery, drug development, and drug manufacturing industry has a history of patent and other intellectual property litigation and these lawsuits will likely continue. This may be exacerbated by the increased use of cell-based and new alternative model methods not involving animal models, which may supplement and/or replace or supplant the use of traditional living animal models in biomedical research. Refer to “Risk Factors – New technologies may be developed, validated and increasingly used in biomedical research, which could reduce demand for some of our products and services.” herein for our assessment of certain other relevant risk factors on this topic. Litigation can be expensive, time consuming, and can divert management’s attention from other business concerns. If we do not prevail in an infringement lawsuit brought against us, we may be compelled by a court to pay substantial damages, including treble damages, and be ordered to stop the challenged activity, or obtain a license on unnegotiated and/or unfavorable terms.
Our by-laws designate the state courts located in the State of Delaware as the sole and exclusive forum for certain actions, including derivative actions, which could limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with the Company and its directors, officers, other employees, or the Company's stockholders and may discourage lawsuits with respect to such claims.
Unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the Company, (2) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company’s stockholders, (3) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or the Company’s certificate of incorporation or the Company’s by-laws (in each case, as they may be amended from time to time), or (4) any action asserting a claim governed by the internal affairs doctrine shall be a state court located within the state of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware). However, this exclusive forum provision will not apply to suits brought under the federal securities laws for which the federal courts have exclusive jurisdiction. If a court were to find the choice of forum provision contained in our by-laws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business and financial condition. Furthermore, although we believe the exclusive forum provision benefits us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, this provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with the Company and its directors, officers, or other employees and may discourage lawsuits with respect to such claims.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
We are involved in legal proceedings that could adversely affect our business, financial condition, and results of operations.
We are involved in legal proceedings related to various matters, including securities litigation, and may become involved in other legal proceedings that arise from time to time in the future. For example, as discussed further in Part I, Item 3, Legal Proceedings, a putative securities class action and derivative securities lawsuit have been filed against the Company, and certain officers and directors, alleging that disclosures about the Company’s practices with respect to the importation of non-human primates were materially false or misleading.
Any claims against us, whether meritorious or not, can be time-consuming, result in costly litigation, be harmful to our reputation, require significant management attention, and divert significant resources. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate and subject to change. Litigation and other claims are subject to inherent uncertainties and management’s view of these matters may change in the future. Given the uncertain nature of legal proceedings generally, we are not able in all cases to estimate the amount or range of loss that could result from an unfavorable outcome. We could incur judgments or enter into settlements of claims that could have a material adverse effect on our results of operations in any particular period.
Labor and Employment Risk Factors
We depend on key personnel and may not be able to retain these employees, which could harm our business.
Our success depends to a significant extent on the continued services of our senior management and other members of management who have skills and industry experience aligned with our strategic objectives. James C. Foster, our Chief Executive Officer and President since 1992 and Chairman since 2000, has held various positions with us for four decades. While we entered into an amended employment agreement with Mr. Foster in 2021, most members of our senior management do not have employment agreements, except in jurisdictions outside of the United States where employment contracts are common for most employees. If Mr. Foster or other members of senior management do not continue in their present positions, our business may be adversely impacted.
If we are unable to attract, hire or retain key team members or a highly skilled and diverse global workforce, it could have a negative impact on our business, financial condition or results of operations.
Because of the specialized scientific nature of our business, we are highly dependent upon attracting and retaining qualified scientific, technical and managerial personnel, while also ensuring an inclusive and diverse culture. We have a strong record of employee retention, and we strive to reduce the impact of the potential loss of existing employees by having an established organizational talent review process that identifies successors and potential talent needs. However, there is still significant competition for qualified personnel in the veterinary, pharmaceutical and biotechnology fields. Failure to retain qualified existing personnel and recruit additional key scientific, technical, and managerial personnel in a timely manner, could harm our business.
We depend on the availability of, and good relations with, our team members.
Our employees are not unionized in the U.S. and employees at some of our European facilities are represented by works councils, collective bargaining agreements, employee representative groups and/or unions, which is consistent with local customs for our industry. Our operations depend on the availability and relative costs of labor and maintaining good relations with employees, which includes supporting their overall wellbeing. If we fail to maintain good relations with our team members or with the labor organizations, we may experience labor strikes or work stoppages, which could adversely affect our financial results.
We acknowledge a specific risk associated with periodic reductions in our workforce. As part of our strategic and operational management, we, from time to time, undertake workforce reductions to align with evolving business trends, market dynamics, or operational efficiency goals. Such actions result in incremental severance and benefits costs and replacing lost talent in the future may result in higher costs, all of which could adversely affect our financial results.
Financial and Accounting Risk Factors
Our debt level could adversely affect our business and growth prospects.
As of December 30, 2023, we had $2.6 billion of debt and finance leases (debt). Our debt could have significant adverse effects on our business, including making it more difficult for us to obtain additional financing on favorable terms; requiring us to dedicate a substantial portion of our cash flows from operations to the repayment of debt and the interest on this debt; limiting our ability to capitalize on significant business opportunities; making us more vulnerable to rising interest rates, and reducing our flexibility to respond to changing business and economic conditions. Disruption in the financial market could also have a material adverse effect on our financial position, results of operations and liquidity. For additional information regarding our debt, please see Note 9, “Long-Term Debt and Finance Lease Obligations”, included in the notes to our consolidated financial statements included elsewhere in this Form 10-K.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Impairment of long lived tangible assets and intangible assets (such as goodwill and other intangible assets) may adversely impact future results of operations.
We have intangible assets, including goodwill, on our balance sheet due to our acquisitions of businesses. The initial identification and valuation of these intangible assets and the determination of the estimated useful lives at the time of acquisition involve use of management judgments and estimates. These estimates are based on, among other factors, projections of cash flows that arise from identifiable intangible assets of acquired businesses and discount rates based on an analysis of our weighted average cost of capital, adjusted for specific risks associated with the assets. Disruptions in global financial markets and deterioration of economic conditions could, among other things, impact the discount rate. Other assumptions used in the valuations and actual cash flows arising from a particular intangible asset could vary from projected cash flows, which could imply different carrying values from those established at the dates of acquisition and which could result in impairment of such assets.
If the future growth and operating results of our business are not as strong as anticipated, overall macroeconomic or industry conditions deteriorate and/or our market capitalization declines, this could impact the assumptions used in establishing the carrying value of goodwill or other intangible assets, as well as long-lived tangible assets, such as property, plant and equipment and operating lease right-of-use assets. Should disruption in the global financial markets and deterioration of economic conditions have a prolonged impact on our industry, triggering events may arise resulting in long-lived tangible asset, intangible asset, or goodwill impairments. To the extent long-lived tangible assets, intangible assets, or goodwill are impaired, their carrying value will be written down to their implied fair values and a charge will be made to our net income. Such an impairment charge could materially and adversely affect our operating results. As of December 30, 2023, the carrying amount of goodwill and other intangibles on our consolidated balance sheet was $4.0 billion, property, plant and equipment was $1.6 billion, and operating lease right-of-use assets was $394.0 million.
General Risk Factors
Since we do not expect to pay any cash dividends for the foreseeable future, our shareholders will benefit from an investment in our common stock only if it appreciates in value.
We have not declared or paid any cash dividends on our common stock, and do not anticipate that we will pay any dividends to holders of our common stock for the foreseeable future. Any payment of cash dividends will be at the discretion of our Board of Directors and will depend on our financial condition, capital requirements, legal requirements, earnings and other factors. Consequently, our shareholders should not rely on dividends to receive a return on their investment.
Our quarterly operating results may vary, which could negatively affect the market price of our common stock.
Our results of operations in any quarter may vary from quarter to quarter and are influenced by the risks discussed above, as well as: changes in the general global economy; changes in the mix of our products and services; cyclical buying patterns of our clients; the financial performance of our strategic and venture capital investments; certain acquisition-related adjustments, including change in fair value of contingent payments both receivable from or payable to counterparties; and the occasional extra week (“53rd week”) that we recognize in a fiscal year (and fourth fiscal quarter thereof), including 2022, due to our fiscal year ending on the last Saturday in December. We believe that operating results for any particular
quarter are not necessarily a meaningful indication of future results. Nonetheless, fluctuations in our quarterly operating results could negatively affect the market price of our common stock.
Increasing focus on environmental, social and governance (ESG) matters, including climate-related issues, may impact our business, financial results or stock price.
There has been increasing public focus by investors, clients, environmental activists, the media and governmental and nongovernmental organizations on a variety of ESG matters. If we are not effective in addressing ESG matters affecting our business, or setting and meeting relevant sustainability and climate-related goals, including our approved greenhouse gas emissions reduction targets, which have been approved by the Science Based Targets Initiative, our reputation and financial results may suffer. We may experience increased costs in order to execute upon our sustainability goals and measure achievement of those goals, which could have an adverse impact on our business and financial condition. Heightened stakeholder focus on ESG matters related to our business requires the continuous monitoring of various and evolving laws, regulations, standards and expectations and the associated reporting requirements. A failure to adequately meet stakeholder expectations may result in noncompliance, the loss of business, reputational impacts, diluted market valuation, an inability to attract clients and an inability to attract and retain top talent. A failure to comply with new laws, regulations, or reporting requirements, could negatively impact our reputation and our business. In addition, our adoption of certain standards or mandated compliance to certain requirements could necessitate additional investments that could impact our profitability.

There are no unresolved comments to be reported in response to Item 1B.
Item 1C. Cybersecurity
Cybersecurity Risk Management and Strategy
Charles River places high importance on identifying and eliminating potential cybersecurity threats to its employees, customers, IT infrastructure, proprietary technologies and confidential information.
Our cybersecurity risk management is based on recognized industry governance frameworks, including the International Organization for Standardization (ISO), the National Institute of Standards and Technology (NIST), the Center for Internet Security Controls (CIS), and the Cloud Security Alliance (CSA). We use these frameworks together with information collected from internal and 3rd party assessments to develop policies such as our technology acceptable use policy for information assets, our access requirements for data, systems, or technologies, and policies for the protection and use of personal information of our employees and customers. We protect our IT assets through industry-standard techniques such as multifactor authentication, malware defenses, network and endpoint monitoring, and access review processes. We also work with our business units to leverage and implement foundational cybersecurity principles, such as security by design, defense-in-depth, least privilege, and resilience-focused backups, throughout our organization. We deliver cybersecurity awareness and confidential information protection training to our employees, and we send our employees ethical simulated phishing and spear-phishing emails to test their compliance with our policies.
We engage third parties to conduct annual penetration testing, and we use external risk assessors to measure our program to industry standard frameworks. Our information security management system is certified to the ISO/IEC 27001:2013 standard by the British Standards Institution (BSI); certificate IS 780367. We also collaborate with experts and industry partners to exchange information about threats, best practices, and trends.
Our cybersecurity risk management extends to risks associated with our use of third-party service and technology providers as well as partnerships with third parties we may enter into. For instance, we conduct risk and compliance assessments of third parties that request access to our IT resources and information or who provide technology products to Charles River.
Our cybersecurity risk management is an important part of our comprehensive business continuity program and enterprise risk management. Our global information security team periodically engages with a cross-functional group of Charles River subject-matter experts and leaders to assess and refine Charles River’s cybersecurity risk posture and preparedness. For example, we regularly evaluate and update contingency strategies for our business in the event that a portion of our IT systems were to be unavailable due to a cybersecurity incident. We practice our response to potential cybersecurity incidents through regular tabletop exercises. We also perform threat hunting and red team exercises.
Through these processes, during our fiscal year 2023 and through the date of this filing we did not identify risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected, or are reasonably likely to materially affect, our business strategy, results of operations, or financial condition. However, despite our efforts, we cannot eliminate all risks from cybersecurity threats, or provide assurances that we have not experienced an undetected cybersecurity incident. For more information about these risks, please see the section titled “Item 1A. Risk Factors – Business and Operational Risk Factors - We have in the past experienced and in the future could experience unauthorized access into our information systems.”
Governance of Cybersecurity Risk Management
Our board of directors, as a whole, has oversight responsibility for Charles River’s strategic and operational risks. The Audit Committee of the Board of Directors has been delegated by the Board responsibility by reviewing and discussing Charles River’s risk assessment and risk management practices, including cybersecurity risks, with members of management. The Audit Committee, in turn, periodically discusses its review and assessment with the board of directors.
Our management team is responsible for day-to-day assessment and management of cybersecurity risks. On our management team, our Chief Information Officer has primary oversight of material risks from cybersecurity threats. The Chief Information Officer is Charles River’s Senior Vice President responsible for the Global Technology organization and for information protection at Charles River. The Chief Information Officer has more than 25 years of experience in the field, including serving as the Senior Vice President of Charles River’s Digital Transformation organization, leading the development and implementation of information technology strategies and roadmaps for digital and automation solutions.
Our Chief Information Security Officer reports to our Chief Information Officer. Our Chief Information Security Officer has more than 25 years of experience working in information technology-related roles, of which 10 years has been in information security leadership, and holds degrees in bio-medical engineering and computer science.
35

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Our Chief Information Officer and Chief Information Security Officer assess our cybersecurity readiness through internal assessment tools as well as third-party control tests, vulnerability assessments, audits, and evaluation against industry standards. We have governance and compliance structures that are designed to elevate issues relating to cybersecurity to our Chief Information Officer and Chief Information Security Officer, such as potential threats or vulnerabilities. We also employ various defensive and monitoring techniques based on industry frameworks and cybersecurity standards.
Our Chief Information Officer and our Chief Information Security Officer meet annually with the full Board, and periodically, but generally at least quarterly, with the Chief Executive Officer, Chief Operations Officer, and Audit Committee to review the company’s information technology systems and discuss key cybersecurity risks. Our Chief Information Security Officer has direct access to the Chair of our Audit Committee and keeps the Audit Committee apprised of any developments that may emerge in between regularly scheduled meetings that require its attention. Additionally, our Incident Response Plan includes escalation protocols to raise occurrences that require attention from the Audit Committee or the board of directors as a whole.
Item 2.    Properties
Approximately 60% of our real estate portfolio (by area) is owned including all facilities over 200,000 square feet. The remaining facilities are owned or covered by either land or facility leases. Within the DSA business, we own or lease large facilities (greater than 50,000 square feet) in 9 countries including the U.S., Canada, Scotland, France, China, Netherlands, and Hungary. We own large RMS facilities in Canada, France, England and the U.S with additional large facilities leased in China and the U.S. Manufacturing is supported in over 10 countries with large, owned properties in the U.S., Ireland, and China which are supplemented by additional leased facilities in the U.S., England, France, and Germany. None of our leases is individually material to our business operations.
Many of our leases have an option to renew and we believe that we will be able to successfully renew expiring leases on satisfactory terms. In each of our reportable segments, we believe that our facilities are adequate for our operations and that suitable additional space will be available when needed. For additional information, see Note 17. Leases included in Item 8, “Financial Statements and Supplementary Data” in this Form 10-K.
We track room utilization on an ongoing basis and, depending on the needs of our clients at given times, we may need to execute on contingency plans for expansion, which average between nine and twenty-four months to complete.
Specific sites may be expanded to accommodate the business requirements resulting from a targeted consolidation plan. We continue to employ a master site planning strategy to proactively evaluate our real estate needs. Sites and leases added to the portfolio by way of acquisition are integrated into our overall real estate strategy. In situations where the associated real estate is leased, and depending on the resolution of these situations, we may be encumbered with the remaining real estate lease obligations. In certain circumstances, we dispose of or consolidate operations, which could result in impairment charges.
Item 3.    Legal Proceedings
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) documentation and related processes and procedures, which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain recent shipments in the United States. The carrying value of the inventory related to these shipments is approximately $27 million as of December 30, 2023, which reflects the value of the shipments in accordance with the Company’s inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena, primarily related to the sourcing of non-human primates, and the Company is cooperating with the request. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or

A putative securities class action was filed on May 19, 2023 against the Company and a number of its current/former officers in the United States District Court for the District of Massachusetts. On August 31, 2023, the court appointed the State Teachers Retirement System of Ohio as lead plaintiff. An amended complaint was filed on November 14, 2023 that, among other things, included only James Foster, the Chief Executive Officer and David R. Smith, the former Chief Financial Officer as defendants along with the Company. The amended complaint asserts claims under §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 (the Exchange Act) on behalf of a putative class of purchasers of Company securities from May 5, 2020 through February 21, 2023, alleging that certain of the Company’s disclosures about its practices with respect to the importation of non-human primates made during the putative class period were materially false or misleading. The Company filed a motion to dismiss. While the Company cannot predict the outcome of this matter, it believes the class action to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.
On November 8, 2023, a stockholder filed a derivative lawsuit in the U.S. District Court of the District of Delaware asserting claims on the Company’s behalf against the members of the Company’s Board of Directors and certain of the Company’s current/former officers (James Foster, the Chief Executive Officer; David R. Smith, the former Chief Financial Officer; and Flavia Pease, the current Chief Financial Officer). The complaint alleges that the defendants breached their fiduciary duties to the Company and its stockholders because certain of the Company’s disclosures about its practices with respect to the importation of non-human primates were materially false or misleading. The complaint also alleges that the defendants breached their fiduciary duties by causing the Company to fail to maintain adequate internal controls over securities disclosure and compliance with applicable law and by failing to comply with the company’s Code of Business Conduct and Ethics. The Company intends to file a motion to dismiss. While the Company cannot predict the outcome of this matter, it believes the derivative lawsuit to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.

Overview
We are a leading, full service, non-clinical global drug development partner. For over 75 years, we have been in the business of providing the research models required in the research and development of new drugs, devices, and therapies. Over this time, we have built upon our original core competency of laboratory animal medicine and science (research model technologies) to develop a diverse portfolio of discovery and safety assessment services, both Good Laboratory Practice (GLP) and non-GLP, that supports our clients from target identification through non-clinical development. We also provide a suite of products and services to support our clients’ manufacturing activities, including our contract development and manufacturing organization (CDMO) business. Utilizing our broad portfolio of products and services enables our clients to create a more efficient and flexible drug development model, which reduces their costs, enhances their productivity and effectiveness, and increases speed to market.
Our client base includes major global pharmaceutical companies, many biotechnology companies; agricultural and industrial chemical, life science, veterinary medicine, medical device, diagnostic and consumer product companies; contract research and contract manufacturing organizations; and other commercial entities, as well as leading hospitals, academic institutions, and government agencies around the world. We currently operate in 155 sites and in over 20 countries worldwide, which numbers exclude certain Insourcing Solutions (IS) sites.
Segment Reporting
Our three reportable segments are Research Models and Services (RMS), Discovery and Safety Assessment (DSA), and Manufacturing Solutions (Manufacturing).
Our RMS reportable segment includes the Research Models, Research Model Services, and Cell Solutions businesses. Research Models includes the commercial production and sale of small research models, as well as the supply of large research models. Research Model Services includes: Genetically Engineered Models and Services (GEMS), which performs contract breeding and other services associated with genetically engineered models; Research Animal Diagnostic Services (RADS), which provides health monitoring and diagnostics services related to research models; and Insourcing Solutions (IS), which provides colony management of our clients’ research operations (including recruitment, training, staffing, and management services) within our clients’ facilities as well as our own vivarium space, utilizing our Charles River Accelerator and Development Lab (CRADL) option. Cell Solutions provides controlled, consistent, customized primary cells and blood components derived from normal and mobilized peripheral blood and bone marrow.
Our DSA segment is comprised of two businesses: Discovery Services and Safety Assessment. We provide regulated and non-regulated DSA services to support the research, development, and regulatory-required safety testing of potential new drugs, including therapeutic discovery and optimization plus in vitro and in vivo studies, laboratory support services, and strategic non-clinical consulting and program management to support product development.
Our Manufacturing reportable segment includes Microbial Solutions, which provides in vitro (non-animal) lot-release testing products, microbial detection products, and species identification services and Biologics Solutions (Biologics), which performs specialized testing of biologics (Biologics Testing Solutions) as well as contract development and manufacturing products and services (CDMO). In December of 2022, we sold the Avian Vaccine Services (Avian) business, reported in the Manufacturing segment, which supplied specific-pathogen-free chicken eggs and chickens.

Fiscal Quarters
Our fiscal year is typically based on 52-weeks, with each quarter composed of 13 weeks ending on the last Saturday on, or closest to, March 31, June 30, September 30, and December 31. A 53rd week in the fourth quarter of the fiscal year is occasionally necessary to align with a December 31 calendar year-end, which occurred in fiscal year 2022.
Business Trends
In fiscal year 2023, biopharmaceutical clients reprioritized their drug development programs and were more cautious with their budgetary spending amidst the uncertainty in the broader market environment, including a slowdown in biotechnology funding activities, as well as macroeconomic challenges, including higher interest rates. The demand and pricing for our products and services continued to increase in fiscal year 2023, but at a slower pace than in recent years.
Despite the near-term market pressures, many of our pharmaceutical and biotechnology clients continued to benefit from the long-term value of strategic outsourcing to improve their operating efficiency and to access capabilities that they do not maintain internally. Many of our large biopharmaceutical clients have continued to increase investments in their drug discovery and early-stage development efforts and have strengthened their relationships with outsourced partners, like Charles River, and biotechnology companies to assist them in bringing new drugs to market. While these clients were more cautious with their early-stage R&D spending in fiscal year 2023, these large biopharmaceutical clients were the principal driver of revenue growth. A reduction in the biotechnology funding environment from peak levels in 2021 resulted in a moderation of demand from small and mid-size biotechnology clients. We have recently experienced an increase in our allowance for credit losses, which increased to $25.7 million as of December 30, 2023 from $11.3 million as of December 31, 2022 and may expect this trend to continue if the biotechnology funding environment remains consistent or further softens. Our ability to continue to deliver our leading suite of research and non-clinical development solutions has endeavored our clients to continue to choose to partner with us for our flexible and efficient outsourcing solutions, broad scientific capabilities, and global scale.
Revenue for RMS increased, principally driven by pricing. China reported healthy growth rates despite pressure from more cautious spending on biomedical research activity from clients within China. Demand for research model services continued to perform well, led by our Insourcing Solutions business, particularly our CRADL™ operations. Clients are increasingly adopting CRADL™’s flexible model to access vivarium space without having to invest in internal infrastructure. To support client demand, we have expanded CRADL™’s footprint both organically and through the acquisition of Explora BioLabs in April 2022. We are confident that research models and services will remain essential tools for our clients’ drug discovery and early-stage development efforts.
DSA continued to benefit from sustained trends in fiscal year 2023. The Safety Assessment revenue growth rate moderated due to our clients’ budgetary spending constraints but continued to report a solid growth rate for the fiscal year due to a combination of price increases and study volume. Safety Assessment growth was supported by the meaningful scale of the backlog for this business, although it has recently decreased. DSA backlog decreased to $2.45 billion as of December 30, 2023 from $3.15 billion as of December 31, 2022.
We believe that our comprehensive scientific capabilities and global scale, as well as the breadth and depth of our scientific expertise, quality, and responsiveness remain key criteria when our clients make the decision to outsource to us. Biotechnology clients continue to move their programs forward and utilize outsourcing to achieve their goal of more efficient and effective drug research to bring innovative new therapies to market. We continued to enhance our Discovery Services capabilities to provide clients with a comprehensive portfolio that enables them to start working with us at the earliest stages of the discovery process. We have accomplished this in recent years through acquisitions and by adding cutting-edge capabilities to our discovery toolkit through technology partnerships. In fiscal year 2023, demand in our Discovery Services business declined, as clients reprioritize their program and conserve their early-stage spending, which resulted in lower proposal activity and a longer lead time to commence new projects.
Revenue for our products and services that support our clients’ manufacturing activities increased across most of our Manufacturing Solutions businesses in fiscal year 2023 however, demand in this reportable segment was impacted by clients’ more cautious spending trends in fiscal year 2023, as well as destocking activities and other challenges associated with CDMO and biopharmaceutical clients. Demand for our cell and gene therapy CDMO services improved meaningfully in fiscal year 2023 as the initiatives that we have implemented to improve the performance of our CDMO business gained traction and generated a healthy pipeline of new business opportunities including working on two commercial products. Charles River remains a premier scientific partner for development, testing, and manufacturing of advanced drug modalities and the acquisition of the CDMO businesses in 2021, Cognate and Vigene, further enhanced our presence in the high-growth cell and gene therapy sector.
In response to recent trends described above, we have undertaken restructuring actions within all reportable segments at various locations across North America, Europe and Asia. This includes workforce right-sizing actions, resulting in severance and transition costs; and costs related to the consolidation of facilities, resulting in asset impairment and accelerated depreciation
41

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
charges. Restructuring charges recognized during fiscal year 2023 were approximately $30 million, of which $18 million related to asset impairment and accelerated depreciation charges and $12 million related to severance charges. We expect that these effectuated actions as well as other upcoming planned actions will result in approximately $60 million to $70 million of cost savings on an annualized basis.
Recent Acquisitions
Our strategy is to augment internal growth of existing businesses with complementary acquisitions. We continue to make strategic acquisitions designed to expand our portfolio of products and services to support the drug discovery and development continuum. Our recent acquisitions are described below.
On November 30, 2023, we completed our acquisition of an additional 41% equity interest of Noveprim Group (“Noveprim”), a leading provider of non-human primates (“NHPs”) used for biomedical, pharmaceutical and toxicological research purposes, resulting in a 90% controlling interest. The acquisition strengthens and diversifies the supply chain for our DSA segment. We had previously acquired a 49% equity stake in 2022 for $90.0 million up-front and additional future contingent payments up to $5.0 million based on future performance. The total preliminary purchase price for the Noveprim acquisition is $374.8 million, which includes $144.6 million additional cash paid for the 41% equity interest, elimination of historical activity and intercompany balances of $198.8 million which includes a remeasurement gain on the 49% equity investment of $103.2 million, contingent consideration of $33.3 million, deferred purchase price of $12.0 million payable from 2024 through 2027, offset by estimated post-closing adjustments for working capital of $13.8 million. The acquisition was funded through a combination of available cash and proceeds from our Credit Facility. This business is reported as part of our DSA reportable segment for NHPs vertically integrated into our Safety Assessment supply chain and the RMS reportable segment for NHPs sold to third party customers.
On January 30, 2023, we acquired SAMDI Tech, Inc., (SAMDI), a leading provider of high-quality, label-free high-throughput screening (HTS) solutions for drug discovery research. The acquisition of SAMDI will provide clients with seamless access to the premier, label-free HTS MS platform and create a comprehensive, library of drug discovery solutions. The purchase price of SAMDI was $62.8 million, net of $0.4 million in cash, inclusive of a 20% strategic equity interest previously owned by us of $12.6 million. The acquisition was funded through a combination of available cash and proceeds from our Credit Facility. This business is reported as part of our DSA reportable segment.
On April 5, 2022, we acquired Explora BioLabs Holdings, Inc. (Explora BioLabs), a provider of contract vivarium research services, providing biopharmaceutical clients with turnkey in vivo vivarium facilities, management and related services to efficiently conduct their early-stage research activities. The acquisition of Explora BioLabs complements our existing Insourcing Solutions business, specifically our CRADL™ footprint, and offers incremental opportunities to partner with an emerging client base, many of which are engaged in cell and gene therapy development. The purchase price of Explora BioLabs was $284.5 million, net of $6.6 million in cash acquired. The acquisition was funded through proceeds from our Credit Facility. This business is reported as part of our RMS reportable segment.
Recent Divestiture
We routinely evaluate strategic fit and fundamental performance of our global infrastructure and divest operations that do not meet key business criteria or where capital could be better deployed in other long-term growth opportunities. On December 20, 2022, we completed the sale of our Avian Vaccine Services (Avian) business to a private investor group for a preliminary purchase price of $167 million in cash, subject to certain customary closing adjustments, and future contingent payments up to an additional $30 million. Prior to divestiture, this business was reported in our Manufacturing reportable segment.
U.S. Government Investigations into Non-Human Primate Supply Chain
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) documentation and related processes and procedures, which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are
42

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain recent shipments in the United States. The carrying value of the inventory related to these shipments is approximately $27 million as of December 30, 2023, which reflects the value of the shipments in accordance with our inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena, primarily related to the sourcing of non-human primates, and the Company is cooperating with the request. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or resolved. The Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities. Refer to Item 1A, “Risk Factors” disclosed herein for our assessment of risk factors surrounding this matter.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S.). The preparation of these financial statements requires us to make certain estimates and assumptions that may affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses during the reported periods and related disclosures. These estimates and assumptions are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates could occur in the future. We base our estimates on our historical experience, trends in the industry, and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from our estimates under different assumptions or conditions. Our significant accounting policies are more fully described in Note 1, “Description of Business and Summary of Significant Accounting Policies”, to our consolidated financial statements contained in Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.
An accounting policy is deemed to be critical if the nature of the estimates or assumptions is material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and the impact of the estimates and assumptions on our consolidated financial statements is or may be material. We believe the following represent our critical accounting policies and estimates used in the preparation of our financial statements:
Revenue Recognition
Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or services to a customer (“transaction price”).
To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing the amount to which we expect to be entitled. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.
When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Generally, we do not extend payment terms beyond one year. Applying the practical expedient, we do not assess whether a significant financing component exists if the period between when we perform our obligations under the contract and when the customer pays is one year or less. Our contracts do not generally contain significant financing components.
Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. We determine standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, we estimate the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.
Contracts are often modified to account for changes in contract specifications and requirements. Contract modifications exist when the modification either creates new, or changes existing, enforceable rights and obligations. Generally, when contract modifications create new performance obligations, the modification is considered to be a separate contract and revenue is recognized prospectively. When contract modifications change existing performance obligations, the impact on the existing transaction price and measure of progress for the performance obligation to which it relates is generally recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.
43

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
Product revenue is generally recognized when the customer obtains control of our product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Service revenue is generally recognized over time as the services are delivered to the customer based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. Depending on which better depicts the transfer of value to the customer, we generally measure our progress using either cost-to-cost (input method) or right-to-invoice (output method). We use the cost-to-cost measure of progress when it best depicts the transfer of value to the customer which occurs as we incur costs on our contract, generally related to fixed fee service contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The costs calculation includes variables such as labor hours, allocation of overhead costs, research model costs, and subcontractor costs. Revenue is recorded proportionally as costs are incurred. The right-to-invoice measure of progress is generally related to rate per unit contracts, as the extent of progress towards completion is measured based on discrete service or time-based increments, such as samples tested or labor hours incurred. Revenue is recorded in the amount invoiced since that amount corresponds directly to the value of our performance to date. During fiscal year 2023, $2.6 billion, or approximately 60%, of our total revenue recognized ($4.1 billion) is DSA service revenue transferred over time.
Intangible Assets (including Goodwill) and certain Biological Assets
We use assumptions and estimates in determining the fair value of assets acquired and liabilities assumed in a business combination. The determination of the fair value of intangible assets (including goodwill) and certain biological assets, which represent a significant portion of the purchase price in certain recent acquisitions, requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such assets are amortizable or non-amortizable and, if the former, the period and the method by which the asset will be amortized. We utilize commonly accepted valuation techniques, such as the income, cost and market approaches, as appropriate, in establishing the fair value of these assets. Typically, key assumptions include projections of cash flows that arise from these assets of acquired businesses as well as discount rates based on an analysis of the weighted average cost of capital, adjusted for specific risks associated with the assets.
In our recent acquisitions, customer relationship intangible assets (also referred to as client relationships) and certain biological assets have been the most significant identifiable assets acquired. To determine the fair value of the acquired client relationships and biological assets, we utilized the multiple period excess earnings model (a commonly accepted valuation technique), which includes the following key assumptions: projections of cash flows from the acquired entities, which included future revenue, cost of revenue, operating income margins, customer attrition rates, productivity rates; as well as discount rates based on a market participant’s weighted average cost of capital. The value of the client relationship acquired was $23 million for fiscal year 2023 and $64 million for fiscal year 2022. The value of the biological assets acquired was $168 million for fiscal year 2023.
We review definite-lived intangible assets for impairment when indication of potential impairment exists, such as a significant reduction in cash flows associated with the assets. Actual cash flows arising from a particular intangible asset could vary from projected cash flows which could imply different carrying values from those established at the dates of acquisition and which could result in impairment of such asset. No significant impairments were recognized during fiscal years 2023 and 2022.
We evaluate goodwill for impairment annually, during the fourth quarter, and when events occur or circumstances change that may reduce the fair value of the asset below its carrying amount. Events or circumstances that might require an interim evaluation include unexpected adverse business conditions, economic factors, unanticipated technological changes or competitive activities, loss of key personnel and acts by governments and courts. Estimates of future cash flows require assumptions related to revenue and operating income growth, asset-related expenditures, working capital levels and other factors. Different assumptions from those made in our analysis could materially affect projected cash flows and our evaluation of goodwill for impairment.
We perform the quantitative impairment test where we compare the fair value of our reporting units to their carrying values. If the carrying values of the net assets assigned to the reporting units exceed the fair values of the reporting units, then we would record an impairment loss equal to the difference. In fiscal years 2023 and 2022 we performed the quantitative goodwill impairment test for our reporting units. Fair value was determined by using a weighted combination of a market-based approach and an income approach, as this combination was deemed to be the most indicative of our fair value in an orderly transaction between market participants. Under the market-based approach, we utilized information about our company as well as publicly available industry information to determine earnings multiples and sales multiples that are used to value our reporting units. Under the income approach, we determined fair value based on the estimated future cash flows of each reporting unit, discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of the reporting unit and the rate of return an outside investor would expect to earn. Our 2023 and 2022 impairment tests indicated that goodwill was not impaired.

Valuation and Impairment of Long-Lived Assets
Long-lived assets to be held and used, including property, plant, and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. Factors we consider important that could trigger an impairment review include, but are not limited to, the following:
significant underperformance relative to expected historical or projected future operating results;
significant negative industry or economic trends; or
significant changes or developments in strategy or operations that negatively affect the utilization of our long-lived assets.
Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset, net of any sublease income, if applicable, and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written-down to their fair values. We measure any impairment based on a projected discounted cash flow method using a discount rate determined by management to be commensurate with the risk inherent in our current business model. Significant judgments are required to estimate future cash flows, including the selection of appropriate discount rates and other assumptions. We may also estimate fair value based on market prices for similar assets, as appropriate. Changes in these estimates and assumptions could materially affect the determination of fair value for these assets. Long-lived asset impairments of $42 million were recognized during fiscal year 2023 and no significant impairments were recognized during 2022.
Income Taxes
We prepare and file income tax returns based on our interpretation of each jurisdiction’s tax laws and regulations. In preparing our consolidated financial statements, we estimate our income tax liability in each of the jurisdictions in which we operate by estimating our actual current tax expense together with assessing temporary differences resulting from differing treatment of items for tax and financial reporting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. Significant management judgment is required in assessing the realizability of our deferred tax assets. In performing this assessment, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In making this determination, under the applicable financial accounting standards, we are allowed to consider the scheduled reversal of deferred tax liabilities, projected future taxable income, and the effects of tax planning strategies. Our valuation allowance was $304.2 million as of December 30, 2023. In the event actual results differ from our estimates, we will adjust our estimates in future periods and may establish additional allowances or reversals as necessary.
We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis and consider various factors, that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, information obtained during in process audit activities and changes in facts or circumstances related to a tax position. We adjust the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Our liabilities for uncertain tax positions can be relieved only if the contingency becomes legally extinguished through either payment to the taxing authority or the expiration of the statute of limitations, the recognition of the benefits associated with the position meet the “more-likely-than-not” threshold or the liability becomes effectively settled through the controversy process. We consider matters to be effectively settled once the taxing authority has completed all of its required or expected examination procedures, including all appeals and administrative reviews; we have no plans to appeal or litigate any aspect of the tax position; and we believe that it is highly unlikely that the taxing authority would re-examine the related tax position. We also accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense.
We generally receive a tax deduction upon the exercise of non-qualified stock options by employees, or the vesting of restricted stock and performance share units held by employees. The stock price, timing, and amount of vesting and exercising of stock-based compensation could materially impact our current tax expense.
Our global operations make the effective tax rate sensitive to significant tax law changes. Several countries have begun to enact legislation to implement the Organization for Economic Cooperation and Development’s (OECD) international tax framework, including the Pillar II global minimum tax regime with effect from January 1, 2024 or later. We are currently monitoring these developments, but do not expect there to be a material financial impact.

Results of Operations
Consolidated Results of Operations and Liquidity
Revenue for fiscal year 2023 was $4.1 billion compared to $4.0 billion in fiscal year 2022. The 2023 increase as compared to the corresponding period in 2022 was $153.3 million, or 3.9%, and was primarily due to increased volume and pricing within our Safety Assessment business and our recent acquisition of Explora BioLabs; partially offset by the divestiture of our Avian business and the effect of changes in foreign currency exchange rates when compared to fiscal year 2022.
In fiscal year 2023, our operating income and operating income margin were $617.3 million and 14.9%, respectively, compared with $651.0 million and 16.4%, respectively, in fiscal year 2022. The decrease in operating income and operating income margins for fiscal year 2023 was primarily due to higher operating costs within our Manufacturing segment, restructuring and asset impairment charges principally in our DSA and Manufacturing segments, and the divestiture of the Avian business; partially offset by contributions of higher revenue described above.
Net income attributable to common shareholders decreased to $474.6 million in fiscal year 2023, from $486.2 million in the corresponding period of 2022. The decrease in net income attributable to common shareholders of $11.6 million was primarily due to lower operating income described above and higher interest expense due to higher interest rates on our variable debt, partially offset by lower income tax expense during fiscal year 2023 compared to the corresponding period of 2022.
During fiscal year 2023, our cash flows from operations was $683.9 million compared with $619.6 million for fiscal year 2022. The increase in net cash provided by operating activities was primarily driven by the amounts and timing of compensation payments and inventory purchases.

RMS revenue increased $53.2 million due primarily to higher research model services revenue, specifically the Insourcing Solutions business, which included the acquisition of Explora BioLabs contributing $15.6 million, higher small research model product revenue in North America and China, and higher large model product revenue due to the acquisition of Noveprim, which contributed $6.1 million; partially offset by the effect of changes in foreign currency exchange rates and the impact of the 53rd week in fiscal year 2022, which had contributed $7.4 million to revenue.
RMS operating income decreased $5.7 million compared to fiscal year 2022. RMS operating income as a percentage of revenue for fiscal year 2023 was 19.5%, a decrease of 220 bps from 21.7% for fiscal year 2022. Operating income and operating income as a percentage of revenue decreased due to higher amortization, operating, and staffing costs due to the acquisition of Explora BioLabs; mix of small research models products and services; and the effect of changes in foreign currency exchange rates.

DSA revenue increased $168.3 million due primarily to service revenue which increased in the Safety Assessment business due to increased demand, principally biopharmaceutical clients, pricing of services, and the acquisition of SAMDI contributing $7.0 million to service revenue; partially offset by decreases in our Discovery Services business and the effect of changes in foreign currency exchange rates and the impact of the 53rd week in fiscal year 2022, which had contributed $37.1 million to revenue.
DSA operating income increased $73.2 million compared to fiscal year 2022. DSA operating income as a percentage of revenue for fiscal year 2023 was 23.2%, an increase of 140 bps from 21.8% for fiscal year 2022. Operating income and operating income as a percentage of revenue increased primarily due to the contribution of higher revenue described above and lower amortization of intangible assets; partially offset by higher legal costs incurred in connection with investigations by the U.S government into the non-human primate supply chain, asset impairment charges related to a Discovery Services site closure and a recently divested site related to our Safety Assessment business, and the absence of certain favorable acquisition-related adjustments to contingent consideration arrangements incurred during 2022 which are recorded in selling, general and administrative costs.

Manufacturing revenue decreased $68.1 million due primarily to the divestiture of our Avian business, which decreased revenue by $77.3 million, lower services revenue from our Biologics Testing business, and the impact of the 53rd week in fiscal year 2022 which contributed $8.2 million to revenue in the prior year; partially offset by increased CDMO and Microbial Solutions service revenue.
Manufacturing operating income decreased $78.8 million compared to fiscal year 2022. Manufacturing operating income as a percentage of revenue for fiscal year 2023 was 12.2%, a decrease of 900 bps from 21.2% for fiscal year 2022. Operating income and operating income as a percentage of revenue decreased primarily due to the divestiture of our Avian business, higher charges related to restructuring activities, and lower operating income due to higher operating costs within our Biologics Solutions business, an asset impairment charge, and the absence of a $19 million impact of a favorable ruling from tax authorities on certain indirect tax positions recorded within selling, general and administrative expense in the corresponding period in 2022.

Unallocated corporate costs consist of selling, general and administrative expenses that are not directly related or allocated to the reportable segments. The increase in unallocated corporate costs of $22.4 million, or 10.7%, compared to fiscal year 2022 is primarily related to an increase in our digital investments as well as higher variable compensation and benefits expenses.

Interest expense for fiscal year 2023 was $136.7 million, an increase of $77.4 million, or 130.6%, compared to $59.3 million in fiscal year 2022. The increase was due primarily to higher interest rates, and the absence of $49.7 million of gains recognized in connection with a debt-related foreign exchange forward contract in the corresponding period in 2022.
Other income, net for fiscal year 2023 was $95.5 million, an increase of $65.0 million, or 213.0%, compared to $30.5 million for fiscal year 2022. The increase was due primarily to a gain on acquisition of $98.5 million for Noveprim, the absence of $46.5 million of foreign currency losses recognized in connection with a U.S. dollar denominated loan borrowed by a non-U.S. entity with a different functional currency, and lower net losses incurred on our venture capital, other strategic equity investments, and life insurance investments as compared to fiscal year 2022; partially offset by the absence of a gain on the divestiture of our Avian business of $123.4 million in fiscal year 2022.

Income tax expense for fiscal year 2023 was $100.9 million, a decrease of $29.5 million compared to $130.4 million for fiscal year 2022. Our effective tax rate was 17.4% for fiscal year 2023 compared to 20.9% for fiscal year 2022. The decrease in our effective tax rate in fiscal year 2023 compared to fiscal year 2022 was primarily attributable to the impact of the non-taxable gain on Noveprim of $98.5 million; partially offset by a decreased tax benefit from stock-based compensation deductions.
Liquidity and Capital Resources
Liquidity and Cash Flows
We currently require cash to fund our working capital needs, capital expansion, acquisitions, and to pay our debt, lease, venture capital and strategic equity investments, and pension obligations. Our principal sources of liquidity have been our cash flows from operations, recent divestitures, supplemented by long-term borrowings. Based on our current business plan, we believe that our existing funds, when combined with cash generated from operations and our access to financing resources, are sufficient to fund our operations for the foreseeable future.

Net cash provided by operating activities$683,898 $619,640 
Net cash provided by cash flows from operating activities represents the cash receipts and disbursements related to all of our activities other than investing and financing activities. Operating cash flow is derived by adjusting our net income for (1) non-cash operating items such as depreciation and amortization, stock-based compensation, loss on debt extinguishment and other financing costs, deferred income taxes, long-lived asset impairment changes, gains and/or losses on venture capital and strategic equity investments, gains and/or losses on divestitures, changes in fair value of contingent consideration, as well as (2) changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in our results of operations. During fiscal year 2023, our cash flows from operations was $683.9 million compared with $619.6 million for fiscal year 2022. The increase in net cash provided by operating activities was primarily driven by the amounts and timing of compensation payments and inventory purchases.

Net cash used in financing activities$(85,521)$(42,397)
For fiscal year 2023, net cash used in financing activities was primarily driven by debt repayments on our Credit Facility offset by borrowings to fund the recent acquisition of Noveprim.
Net cash used in financing activities also reflected treasury stock purchases of $24.2 million made due to the netting of common stock upon vesting of stock-based awards in order to satisfy individual statutory tax withholding requirements, $4.8 million payment to purchase the remaining 8% interest in our Vital River subsidiary, $4.0 million of dividends paid to noncontrolling interests, and $2.7 million of contingent consideration payments; partially offset by proceeds from exercises of employee stock options of $25.6 million. We did not pay any dividends on our Common Stock in fiscal year 2023 and have no current plans to do so in the coming fiscal year.
For fiscal year 2022, net cash used in financing activities reflected the net proceeds of $19.8 million on our Credit Facility and finance lease obligations. Included in the net proceeds are the following amounts:
Borrowings under our Credit Facility of $300 million, which were used primarily for the acquisition of Explora BioLabs;
Net repayments of $100 million on our Credit Facility throughout fiscal year 2022;
Payments of $2.0 billion partially offset by $1.9 billion of proceeds in connection with a non-U.S. Euro functional currency entity repaying Euro loans and replacing the Euro loans with U.S. dollar denominated loans. A series of forward currency contracts were executed to mitigate any foreign currency gains or losses on the U.S. dollar denominated loans. These proceeds and payments are presented as gross financing activities.
Net cash used in financing activities also reflected treasury stock purchases of $38.7 million made due to the netting of common stock upon vesting of stock-based awards in order to satisfy individual statutory tax withholding requirements, approximately $15 million payment to purchase an additional 10% interest in a subsidiary, $15.7 million payment to acquire the remaining 2% ownership interest in Cognate, $10.4 million of contingent consideration payments, and $5.3 million of dividends paid to noncontrolling interests; partially offset by proceeds from exercises of employee stock options of $25.1 million.

Financing and Market Risk
We are exposed to market risk from changes in interest rates and currency exchange rates, which could affect our future results of operations and financial condition. We manage our exposure to these risks through our regular operating and financing activities.
Amounts outstanding under our Credit Facility and our Senior Notes were as follows:
December 30, 2023December 31, 2022

Revolving facility$1,129,243 $1,197,586

4.0% Senior Notes due 2031500,000 500,000 
Total$2,629,243 $2,697,586 
The interest rates applicable to the Credit Facility are equal to (A) for revolving loans denominated in U.S. dollars, at the Company’s option, either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.50%, or (3) the one-month adjusted SOFR rate plus 1.0%) or the adjusted SOFR rate, (B) for revolving loans denominated in euros, the adjusted EURIBOR rate and (C) for revolving loans denominated in sterling, the daily simple SONIA rate, in each case, plus an interest rate margin based upon the Company’s leverage ratio. In March 2023 and in conjunction with the Credit Agreement second amendment (Second Amendment) the Company modified the variable rate on the Credit Facility from adjusted LIBOR to adjusted term SOFR. All outstanding U.S. dollar borrowings remained at adjusted LIBOR through their respective interest reset periods in April 2023 and were then set to term SOFR.
Our 2028 Senior Notes have semi annual interest payments due May 1 and November 1. Our 2029 and 2031 Senior Notes have semi annual interest payments due March 15 and September 15.
During the fourth fiscal quarter of 2022, we entered into an interest rate swap with a notional amount of $500 million to manage interest rate fluctuation related to our floating rate borrowings under the Credit Facility, at a fixed rate of 4.70%. In March 2023 and in conjunction with the Second Amendment, we modified the variable rate on our interest rate swap from 1-month LIBOR to 1-month term SOFR. Effective with the modification we will pay a fixed rate of 4.65% on our swap maturing November 2, 2024. The transition did not have an impact on our hedge accounting or a material impact to our consolidated financial statements.
Our off-balance sheet commitments related to our outstanding letters of credit as of December 30, 2023 were $21.6 million.
Foreign Currency Exchange Rate Risk
We operate on a global basis and have exposure to some foreign currency exchange rate fluctuations for our financial position, results of operations, and cash flows.
While the financial results of our global activities are reported in U.S. dollars, our foreign subsidiaries typically conduct their operations in their respective local currency. The principal functional currencies of our foreign subsidiaries are the Euro, British Pound, and Canadian Dollar. During fiscal year 2023, the most significant drivers of foreign currency translation adjustment we recorded as part of other comprehensive income (loss) were the British Pound, Euro, Canadian Dollar, and Hungarian Forint.
Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our financial position, results of operations, and cash flows. As the U.S. dollar strengthens against other currencies, the value of our non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally decline when reported in U.S. dollars. The impact to net income as a result of a U.S. dollar strengthening will be partially mitigated by the value of non-U.S. expenses, which will decline when reported in U.S. dollars. As the U.S. dollar weakens versus other currencies, the value of the non-U.S. revenue, expenses, assets, liabilities, and cash flows will generally increase when reported in U.S. dollars. For fiscal year 2023, our revenue would have decreased by $126.7 million and our operating income would have decreased by $2.8 million, if the U.S. dollar exchange rate had strengthened by 10%, with all other variables held constant.
We attempt to minimize this exposure by using certain financial instruments in accordance with our overall risk management and our hedge policy. We do not enter into speculative derivative agreements.
We entered into foreign exchange forward contracts during fiscal year December 31, 2022 to limit our foreign currency exposure related to a U.S. dollar denominated loan borrowed by a non-U.S. Euro functional currency entity under the Credit Facility. Refer to Note 11. Debt and Other Financing Arrangements to our consolidated financial statements contained in Item

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
8, “Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K for further details regarding these types of forward contracts.
Repurchases of Common Stock
During fiscal year 2023, we did not repurchase any shares under our authorized $1.3 billion stock repurchase program. As of December 30, 2023, we had $129.1 million remaining on the authorized stock repurchase program. Our stock-based compensation plans permit the netting of common stock upon vesting of restricted stock, restricted stock units, and performance share units in order to satisfy individual statutory tax withholding requirements. During fiscal year 2023, we acquired 0.1 million shares for $24.2 million through such netting.
Commitments and Other Purchasing Arrangements
We lease properties and equipment for use in our operations. In addition to rent, the leases may require us to pay additional amounts for taxes, insurance, maintenance, and other operating expenses. As of December 30, 2023, we had $757.4 million of operating leases inclusive of future minimum rental commitments under non-cancellable operating leases, net of income from subleases as well as $39.9 million of financing leases. The expected payments of our operating and finance lease liabilities over the next twelve months are $70.6 million and $3.8 million, respectively as of December 30, 2023.
In addition to the obligations on the balance sheet at December 30, 2023, we entered into unconditional purchase obligations in the ordinary course of business. Unconditional purchase obligations include agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms, including fixed or minimum quantities to be purchased, fixed, minimum or variable price provisions, and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancellable at any time without penalty. As of December 30, 2023, we had approximately $390 million of unconditional purchase obligations, the majority of which are expected to be settled during 2024.
We invest in several venture capital funds that invest in start-up companies, primarily in the life sciences industry. Our total commitment to the funds as of December 30, 2023 was $212.9 million, of which we funded $145.2 million through December 30, 2023.
Refer to Note 8. Venture Capital and Strategic Equity Investments to our consolidated financial statements contained in Item 8, “Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K for further details.
In connection with certain business and asset acquisitions, we agreed to make additional payments based upon the achievement of certain financial targets and other milestones in connection with the respective acquisition. As of December 30, 2023, we had approximately $98 million of gross contingent payments, of which $33 million are expected to be paid.
We have certain federal and state income tax liabilities of $32.4 million relating to the one-time Transition Tax on unrepatriated earnings under the 2017 Tax Act. The Transition Tax will be paid, interest free, over an eight-year period through 2026.

We have audited the accompanying consolidated balance sheets of Charles River Laboratories International, Inc. and its subsidiaries (the “Company”) as of December 30, 2023 and December 31, 2022, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 30, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 30, 2023 and December 31, 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 30, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 30, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
As described in Management’s Report on Internal Control Over Financial Reporting, management has excluded Noveprim Group (“Noveprim”) from its assessment of internal control over financial reporting as of December 30, 2023, because it was acquired by the Company in a purchase business combination during 2023. We have also excluded Noveprim from our audit of internal control over financial reporting. Noveprim is a subsidiary whose total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting represent less than 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 30, 2023.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over
55

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Acquisition of Noveprim – Valuation of Biological Assets
As described in Notes 1 and 2 to the consolidated financial statements, on November 30, 2023, the Company completed the acquisition of Noveprim, resulting in a 90% controlling interest. Of the acquired long-term assets, $167.8 million of biological assets were recorded. The determination of the fair value of biological assets requires the use of significant judgment using management’s best estimates of inputs and assumptions that a market participant would use. To determine the fair value, management utilized the multiple period excess earnings model, which relies on the following key assumptions: projections of cash flows from the acquired entities, which includes future revenue, cost of revenue, operating income margins, and productivity rates, as well as the discount rate based on market participant’s weighted average cost of capital.
The principal considerations for our determination that performing procedures relating to the valuation of biological assets acquired in the acquisition of Noveprim is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the biological assets acquired; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions related to the cost of revenue, productivity rates, and discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the acquisition accounting, including controls over management’s valuation of the biological assets acquired. These procedures also included, among others (i) reading the purchase agreement; (ii) testing management’s process for developing the fair value estimate of the biological assets acquired; (iii) evaluating the appropriateness of the multiple period excess earnings model; (iv) testing the completeness and accuracy of the underlying data used in the multiple period excess earnings model; and (v) evaluating the reasonableness of the significant assumptions used by management related to the cost of revenue, productivity rates, and discount rate. Evaluating management’s assumptions related to the cost of revenue and productivity rates involved considering (i) the past performance of Noveprim; (ii) the consistency with external research data; and (iii) whether the assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the multiple period excess earnings model and (ii) the reasonableness of the discount rate assumption.
Discovery and Safety Assessment Service Revenue Recognized Over Time Using the Input Method
As described in Notes 1 and 3 to the consolidated financial statements, the Company recognized Discovery and Safety Assessment (DSA) revenue from services and products transferred over time of $2,611.6 million for the year-ended December 30, 2023, of which the majority relates to services that are delivered to the customer based on the extent of progress towards completion of the performance obligation that management
56

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
measures using the cost-to-cost (input method). Management uses the input method measure of progress when it best depicts the transfer of value to the customer, which occurs as the Company incurs costs on its contract, generally related to fixed fee service contracts. Under the input method measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The cost calculation includes variables such as labor hours, allocation of overhead costs, research model costs, and subcontractor costs. Revenue is recorded proportionally as costs are incurred.
The principal considerations for our determination that performing procedures relating to DSA service revenue recognized over time using the input method is a critical audit matter are a high degree of auditor subjectivity and effort in performing procedures and evaluating audit evidence related to the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to DSA service revenue recognized over time using the input method, including controls over the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation, review of contracts, testing of budget versus actual costs incurred, and testing of revenue recognition. These procedures also included, among others (i) reading contracts and reports describing the results of services provided for a sample of DSA service contracts; (ii) testing management’s process for determining the amount of DSA service revenue recognized over time for a sample of DSA service contracts; (iii) evaluating the appropriateness of the input method used by management; (iv) evaluating the reasonableness of the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations through performing a retrospective comparison of actual costs incurred to historical estimated costs for completed service contracts; and (v) testing actual costs incurred for a sample of in-progress service contracts by examining evidence of costs incurred.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Description of Business
Charles River Laboratories International, Inc. (the Company), together with its subsidiaries, is a full service, non-clinical global drug development partner. The Company has built upon its core competency of laboratory animal medicine and science (research model technologies) to develop a diverse portfolio of discovery and safety assessment services, both Good Laboratory Practice (GLP) and non-GLP, that enable the Company to support its clients from target identification through non-clinical development. The Company also provides a suite of products and services to support its clients’ manufacturing activities.
Principles of Consolidation
The Company’s consolidated financial statements reflect its financial statements and those of its subsidiaries in which the Company holds a controlling financial interest. For consolidated entities in which the Company owns or is exposed to less than 100% of the economics, the Company records net income (loss) attributable to noncontrolling interests in its consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. Redeemable noncontrolling interests, where the noncontrolling interest holders have the ability to require the Company to purchase the remaining interests, are classified in the mezzanine section of the consolidated balance sheets, which is presented above the equity section and below liabilities. Intercompany balances and transactions are eliminated in consolidation.
The Company’s fiscal year is typically based on 52-weeks, with each quarter composed of 13 weeks ending on the last Saturday on, or closest to, March 31, June 30, September 30, and December 31. A 53rd week in the fourth quarter of the fiscal year is occasionally necessary to align with a December 31 calendar year-end, which occurred in fiscal year 2022.
Segment Reporting
The Company reports its results in three reportable segments: Research Models and Services (RMS), Discovery and Safety Assessment (DSA), and Manufacturing Solutions (Manufacturing). The Company’s RMS reportable segment includes the Research Models, Research Model Services, and Cell Solutions businesses.
Research Models includes the commercial production and sale of small research models, as well as the supply of large research models. Research Model Services includes: Insourcing Solutions (IS), which provides colony management of its clients’ research operations (including recruitment, training, staffing, and management services) within our clients’ facilities and utilizing our Charles River Accelerator and Development Lab (CRADL™) offering, which provides vivarium space to clients, Genetically Engineered Models and Services (GEMS), which performs contract breeding and other services associated with genetically engineered models, and Research Animal Diagnostic Services (RADS), which provides health monitoring and diagnostics services related to research models; and Cell Solutions, which supplies controlled, consistent, customized primary cells and blood components derived from normal and mobilized peripheral blood and bone marrow.
The Company’s DSA reportable segment includes two businesses: Discovery Services and Safety Assessment. The Company provides regulated and non-regulated DSA services to support the research, development, and regulatory-required safety testing of potential new drugs, including therapeutic discovery and optimization plus in vitro and in vivo studies, laboratory support services, and strategic non-clinical consulting and program management to support product development.
The Company’s Manufacturing reportable segment includes Microbial Solutions, which provides in vitro (non-animal) lot-release testing products, microbial detection products, and species identification services and Biologics Solutions (Biologics), which performs specialized testing of biologics (Biologics Testing Solutions) as well as contract development and manufacturing products and services (CDMO). In December of 2022, the Company sold the Avian Vaccine Services business (Avian), reported in the Manufacturing segment, which supplied specific-pathogen-free chicken eggs and chickens.
Use of Estimates
The preparation of consolidated financial statements in accordance with generally accepted accounting principles in the United States (U.S. GAAP) requires that the Company make estimates and judgments that may affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, judgments, and methodologies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
As of the date of issuance of these consolidated financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update estimates, judgments or revise the carrying value of any assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s consolidated financial statements.
Newly Adopted Accounting Pronouncements
In September 2022, the FASB issued ASU 2022-04, “Liabilities – Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations.” ASU 2022-04 requires quantitative and qualitative disclosures about the use of supplier finance programs. The ASU is effective for fiscal years beginning after December 15, 2022, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years for selected disclosures, and will be applied on a prospective basis. The Company participates in certain supplier finance programs that are immaterial to the consolidated financial statements and related disclosures.
Newly Issued Accounting Pronouncements
In November 2023, the FASB issued ASU 2023-07, “Improvements to Reportable Segment Disclosures (Topic 280)”. ASU 2023-07 modifies reportable segment disclosure requirements, primarily through enhanced disclosures about segment expenses categorized as significant or regularly provided to the Chief Operating Decision Maker (CODM). In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. This ASU is effective for annual periods beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact this new standard will have on the related disclosures in the consolidated financial statements, but does not believe there will be a material impact.
In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures (Topic 740)”. ASU 2023-09 requires enhanced disclosures on income taxes paid, adds disaggregation of continuing operations before income taxes between foreign and domestic earnings and defines specific categories for the reconciliation of jurisdictional tax rate to effective tax rate. This ASU is effective for fiscal years beginning after December 15, 2024, and can be applied on a prospective basis. The Company is currently evaluating the impact this new standard will have on the related disclosures in the consolidated financial statements.
Cash, Cash Equivalents, and Investments
Cash equivalents include money market funds, time deposits and other investments with remaining maturities at the purchase date of three months or less. Time deposits with original maturities of greater than three months are reported as short-term investments.
Trade Receivables and Contract Assets, Net
The Company records trade receivables and contract assets, net of an allowance for credit losses. An allowance for credit losses is established based on historical collection information, a review of major client accounts receivable balances, current economic conditions in the geographies in which it operates, and the Company’s expectations of future economic conditions that may affect the collectability of the recorded amounts. Amounts determined to be uncollectible are charged or written off against the allowance.
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, investments, trade receivables and contract assets. The Company places cash and cash equivalents and investments in various financial institutions with high credit rating and limits the amount of credit exposure to any one financial institution. Trade receivables and contract assets are primarily from clients in the pharmaceutical and biotechnology industries, as well as academic and government institutions. Concentrations of credit risk with respect to trade receivables and contract assets, which are typically unsecured, are limited due to the wide variety of customers using the Company’s products and services as well as their dispersion across many geographic areas. No single client accounted for more than 3.5% of revenue in fiscal years 2023, 2022, or 2021 or trade receivables as of December 30, 2023 or December 31, 2022.
Fair Value Measurements
The accounting standard for fair value measurements defines fair value, establishes a framework for measuring fair value in accordance with U.S. GAAP, and requires certain disclosures about fair value measurements. Under this standard, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
64

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
participants at the measurement date. The Company has certain financial assets and liabilities recorded at fair value, which have been classified as Level 1, 2 or 3 within the fair value hierarchy:
Level 1 - Fair values are determined utilizing prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access,
Level 2 - Fair values are determined by utilizing quoted prices for identical or similar assets and liabilities in active markets or other market observable inputs such as interest rate yield curves and foreign currency spot rates,
Level 3 - Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
The fair value hierarchy level is determined by asset and class based on the lowest level of significant input. The observability of inputs may change for certain assets or liabilities. This condition could cause an asset or liability to be reclassified between levels. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each quarter.
Valuation methodologies used for assets and liabilities measured or disclosed at fair value are as follows:
Cash equivalents - Valued at market prices determined through third-party pricing services;
Foreign currency forward contracts - Valued using market observable inputs, such as forward foreign exchange points and foreign exchanges rates;
Interest rate swap contracts - Valued using market observable inputs, such as interest rate yield curves;
Life insurance policies - Valued at cash surrender value based on the fair value of underlying investments;
Debt instruments - The book value of the Company’s revolving loans, which are variable rate loans carried at amortized cost, approximates the fair value based on current market pricing of similar debt. The book values of the Company’s Senior Notes, which are fixed rate debt, are carried at amortized cost. Fair values of the Senior Notes are based on quoted market prices and on borrowing rates available to the Company; and
Contingent consideration - Valued based on a probability weighting of the future cash flows associated with the potential outcomes and certain option pricing models.
Inventories
The Company’s inventories consist of raw materials, work in process and finished product related primarily to small models, large models, cell solutions, microbial solutions, and CDMO products. Inventories are stated at the lower of cost or net realizable value. Inventory value is generally based on the standard cost method for all businesses. Standard costs are trued-up to reflect actual cost. For small models inventory, costs include direct materials such as feed and bedding, costs of personnel directly involved in the care of the models, and an allocation of facility overhead. For the large models inventory, costs are primarily the external cost paid to acquire the model along with certain direct materials, costs of personnel directly involved in the care of the models, and allocation of facility overhead costs. For cell solutions inventory, costs include direct materials, costs of personnel directly involved in the processing of products sold, and an allocation of facility overhead. For the microbial solutions and CDMO inventory, costs include direct materials, cost of personnel directly involved in the manufacturing and assembly of products sold, and an allocation of facility overhead. Inventory costs are charged to cost of revenue in the period the products are sold to an external party. The Company analyzes its inventory levels on a quarterly basis and writes down inventory that is determined to be damaged, obsolete or otherwise unmarketable, with a corresponding charge to cost of products sold.
Property, Plant and Equipment, Net
Property, plant and equipment, net, including improvements that significantly add to productive capacity or extend useful life, are carried at cost and are subject to review for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset or asset group may not be recoverable. The cost of normal, recurring, or periodic repairs and maintenance activities related to property, plant and equipment is expensed as incurred. In addition, the Company capitalizes certain internal use computer software development costs. Costs incurred during the preliminary project stage are expensed as incurred, while costs incurred during the application development stage are capitalized and amortized over the estimated useful life of the software. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Maintenance and training costs related to software obtained for internal use are expensed as incurred.
Interest costs incurred during the construction of major capital projects are capitalized until the underlying asset is ready for its intended use, at which point the interest costs are amortized as depreciation expense over the life of the underlying asset.
65

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The Company generally depreciates the cost of its property, plant and equipment using the straight-line method over the estimated useful lives of the respective assets as follow:
Estimated
Useful Lives
(in years)
LandIndefinite
Buildings and building improvements
10 - 40
Machinery and equipment
3 - 20
Furniture and fixtures
5 - 10
Computer hardware and software
3 - 8
Vehicles
3 - 5
Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the lease term. Finance lease assets are amortized over the lease term, however, if ownership is transferred by the end of the finance lease, or there is a bargain purchase option, such finance lease assets are amortized over the useful life that would be assigned if such assets were owned.
When the Company disposes of property, plant and equipment, it removes the associated cost and accumulated depreciation from the related accounts on its consolidated balance sheet and includes any resulting gain or loss recorded in Other (expense) income, net in the accompanying consolidated statements of income.
Business Combinations
The Company accounts for business combinations under the acquisition method of accounting. The Company allocates the amounts that it pays for each acquisition to the assets it acquires and liabilities it assumes based on their fair values at the dates of acquisition, including identifiable intangible assets and certain biological assets, which can represent a significant portion of the purchase price. The determination of the fair value of intangible and certain biological assets requires the use of significant judgment using management’s best estimates of inputs and assumptions that a market participant would use. Significant judgments include (i) the fair value; and (ii) whether such assets are amortizable or non-amortizable and, if the former, the period and the method by which the asset will be amortized. The Company utilizes commonly accepted valuation techniques, such as the income, cost, and market approaches as appropriate, in establishing the fair value of assets. Typically, key assumptions include projections of cash flows that arise from identifiable assets of acquired businesses as well as discount rates based on an analysis of the weighted average cost of capital, adjusted for specific risks associated with the assets.
In recent acquisitions, customer relationship intangible assets (also referred to as client relationships) and certain biological assets are the most significant identifiable asset acquired. To determine the fair value of these acquired assets, the Company typically utilizes the multiple period excess earnings model (a commonly accepted valuation technique), which relies on the following key assumptions: projections of cash flows from the acquired entities, which includes future revenue, cost of revenue, operating income margins, customer attrition rates, and productivity rates; as well as discount rates based on a market participant’s weighted average cost of capital.
Contingent Consideration
The consideration for the Company’s acquisitions may include future payments that are contingent upon the occurrence of a particular event. The Company records an obligation for such contingent payments at fair value on the acquisition date. The Company estimates the fair value of contingent consideration obligations through valuation models, such as probability-weighted and option pricing models, that incorporate probability adjusted assumptions and simulations related to the achievement of the milestones and the likelihood of making related payments. The Company revalues these contingent consideration obligations each reporting period. Changes in the fair value of the contingent consideration obligations are recognized in the Company’s consolidated statements of income as a component of selling, general and administrative expenses. Changes in the fair value of the contingent consideration obligations can result from changes to one or multiple inputs, including adjustments to the discount rates and changes in the assumed probabilities of successful achievement of certain financial targets.
Discount rates in the Company’s valuation models represent a measure of the credit risk associated with settling the liability. The period over which the Company discounts its contingent obligations is typically based on when the contingent payments would be triggered. These fair value measurements are based on significant inputs not observable in the market.
Divestitures
The Company records divestitures at fair value less cost to sell with any related gain or loss from sale recorded within Other income (expense) on the Company’s consolidated statements of income. If the sale price includes contingent payments, these
66

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
are fair valued using a probability weighted model. If the business divested is part of a reporting unit, goodwill from the reporting unit is reallocated based on the fair value of the divested business compared to the fair value of the reporting unit.
Goodwill and Intangible Assets
Goodwill represents the difference between the purchase price and the fair value of assets acquired and liabilities assumed when accounted for using the acquisition method of accounting. Goodwill is not amortized, but reviewed for impairment on an annual basis, during the fourth quarter, or more frequently if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of the Company's reporting units below their carrying amounts.
The Company has the option to first assess qualitative factors to determine whether it is necessary to perform the quantitative impairment test. If the Company elects this option and believes, as a result of the qualitative assessment, that it is more-likely-than-not that the carrying value of goodwill is not recoverable, the quantitative impairment test is required; otherwise, no further testing is required. Alternatively, the Company may elect to not first assess qualitative factors and immediately perform the quantitative impairment test. In the quantitative test, the Company compares the fair value of its reporting units to their carrying values. If the carrying values of the net assets assigned to the reporting units exceed the fair values of the reporting units an impairment loss equal to the difference would be recorded.
Definite-lived intangible assets, including client relationships, are amortized over the pattern in which the economic benefits of the intangible assets are utilized and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset or asset group. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the definite-lived intangible assets, the definite-lived intangible assets are written-down to their fair values.
Valuation and Impairment of Long-Lived Assets
Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable.
Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written-down to their fair values.
Long-lived assets to be disposed of are carried at fair value less costs to sell.
Venture Capital Investments
The Company invests in several venture capital funds that invest in start-up companies, primarily in the life sciences industry. The Company’s ownership interest in these funds ranges from less than 1% to approximately 12%. The Company accounts for the investments in limited partnerships (LPs), which are variable interest entities, under the equity method of accounting. For publicly-held investments in the LPs, the Company adjusts for changes in fair market value based on reported share holdings at the end of each fiscal quarter. The Company is not the primary beneficiary because it has no power to direct the activities that most significantly affect the LPs’ economic performance.
Under the equity method of accounting, the Company’s portion of the investment gains and losses, as reported in the fund’s financial statements on a quarterly lag each reporting period, is recorded in Other (expense) income, net in the accompanying consolidated statements of income. In addition, the Company adjusts the carrying value of these investments to reflect its estimate of changes to fair value since the fund’s financial statements are based on information from the fund’s management team, market prices of known public holdings of the fund, and other information.
Strategic Equity Investments
The Company invests, with minority positions, directly in equity of predominantly privately-held companies that are reported either at fair value or under the equity method of accounting, as appropriate. Equity investments that do not have readily determinable fair values are generally recorded at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same investee. Gains and losses from strategic equity investments are recorded in Other (expense) income, net in the accompanying consolidated statements of income.
67

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Derivative Contracts
The Company is exposed to certain risks relating to its ongoing business operations including changes to interest rates and currency exchange rates. The company uses derivative instruments primarily to manage currency exchange and interest rate risks. The Company recognizes derivative instruments as either assets or liabilities and measures those instruments at fair value. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged item through earnings or recognized in other comprehensive items until the hedged item is recognized in earnings. Derivatives that are not designated as hedges are recorded at fair value through earnings.
For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive items and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item. The Company uses an interest rate swap to manage interest rate fluctuation related to floating rate borrowings under the Credit Facility.
The Company uses short-term forward currency exchange contracts primarily to hedge certain balance sheet and operational exposures resulting from changes in currency exchange rates, predominantly intercompany loans. The currency-exchange contracts principally hedge transactions denominated in Canadian dollars and euros. The Company does not hold or engage in transactions involving derivative instruments for purposes other than risk management.
Life Insurance Contracts
Investments in life insurance contracts are recorded at cash surrender value. The initial investment is remeasured based on fair value of underlying investments or contractual value each reporting period. Gains and losses from life insurance contracts are recorded in Other income (expense), net in the accompanying consolidated statements of income. Investments in and redemptions of these life insurance contracts are reported as cash flows from investing activities in the consolidated statement of cash flows. The Company held 44 contracts at December 30, 2023 with a face value of $82.4 million and 44 contracts with a face value of $74.5 million at December 31, 2022, which are recorded in Other assets.
Leases
At inception of a contract, the Company determines if a contract meets the definition of a lease. A lease is a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. The Company determines if the contract conveys the right to control the use of an identified asset for a period of time. The Company assesses throughout the period of use whether the Company has both of the following: (1) the right to obtain substantially all of the economic benefits from use of the identified asset, and (2) the right to direct the use of the identified asset. This determination is reassessed if the terms of the contract are changed. Leases are classified as operating or finance leases based on the terms of the lease agreement and certain characteristics of the identified asset. Right-of-use assets and lease liabilities are recognized at lease commencement date based on the present value of the minimum future lease payments.
The Company leases laboratory, production, and office space (real estate), as well as land, vehicles and certain equipment under non-cancellable operating and finance leases. The carrying value of the Company’s right-of-use lease assets is substantially concentrated in its real estate leases, while the volume of lease agreements is primarily concentrated in vehicles and equipment leases. The Company’s policy is to not record leases with an original term of twelve months or less on the consolidated balance sheets. The Company recognizes lease expense for these short-term leases on a straight-line basis over the lease term.
Certain lease agreements include rental payments that are adjusted periodically for inflation or other variables. In addition to rent, the leases may require the Company to pay additional amounts for taxes, insurance, maintenance and other expenses, which are generally referred to as non-lease components. Such adjustments to rental payments and variable non-lease components are treated as variable lease payments and recognized in the period in which the obligation for these payments was incurred. Variable lease components and variable non-lease components are not measured as part of the right-of-use asset and liability. Only when lease components and their associated non-lease components are fixed are they accounted for as a single lease component and are recognized as part of a right-of-use asset and liability. Total contract consideration is allocated to the combined fixed lease and non-lease component. This policy election applies consistently to all asset classes under lease agreements.
Most real estate leases contain clauses for renewal at the Company’s option with renewal terms that generally extend the lease term from 1 to 5 years. Certain lease agreements contain options to purchase the leased property and options to terminate the lease. Payments to be made in option periods are recognized as part of the right-of-use lease assets and lease liabilities when it is reasonably certain that the option to extend the lease will be exercised or the option to terminate the lease will not be exercised, or is not at the Company’s option. The Company determines whether the reasonably certain threshold is met by considering contract-, asset-, market-, and entity-based factors.
68

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
A portfolio approach is applied to certain lease contracts with similar characteristics. The Company’s lease agreements do not contain any significant residual value guarantees or material restrictive covenants imposed by the leases.
The Company subleases a limited number of lease arrangements. Sublease activity is not material to the consolidated financial statements.
Stock-Based Compensation
The Company grants stock options, restricted stock units (RSUs), and performance share units (PSUs) to employees and stock options, and RSUs to non-employee directors under stock-based compensation plans. Stock-based compensation is recognized as an expense in the consolidated statements of income based on the grant date fair value, adjusted for forfeitures when they occur, over the requisite service period.
For stock options and RSUs that vest based on service conditions, the Company uses the straight-line method to allocate compensation expense to reporting periods. Where awards are made with non-substantive vesting periods and a portion of the award continues to vest after the employee’s eligible retirement, the Company recognizes expense based on the period from the grant date to the date on which the employee is retirement eligible. The Company records the expense for PSU grants subject to performance and/or market conditions using the accelerated attribution method over the remaining service period when management determines that achievement of the performance-based milestone is probable.
The fair value of stock options granted is calculated using the Black-Scholes option-pricing model and the fair value of PSUs is estimated using a lattice model with a Monte Carlo simulation, both of which require the use of subjective assumptions including volatility and expected term, among others. The expected volatility assumption is typically determined using the historical volatility of the Company’s common stock over the expected life of the stock-based award. The expected term is determined using historical option exercise activity. The fair value of RSUs is based on the market value of the Company’s common stock on the date of grant.
Revenue Recognition
Revenue is recognized when, or as, obligations under the terms of a contract are satisfied, which occurs when control of the promised products or services is transferred to customers. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer (“transaction price”).
To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the amount to which the Company expects to be entitled. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.
When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Generally, the Company does not extend payment terms beyond one year. Applying the practical expedient, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. The Company’s contracts do not generally contain significant financing components.
Contracts with customers may contain multiple performance obligations. For such arrangements, the transaction price is allocated to each performance obligation based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.
As part of the Company’s service offerings, the Company has identified performance obligations related to leasing Company owned assets. In certain arrangements, customers obtain substantially all of the economic benefits of the identified assets, which may include manufacturing suites and related equipment, and have the right to direct the assets’ use over the term of the contract. The associated revenue is recognized on a straight-line basis over the term of the lease, which is generally less than one year, and recorded within service revenue. Due to the nature of these arrangements and timing of the contractual lease term, the remaining revenue to be recognized related to these lease performance obligations is not material to the consolidated financial statements.
69

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Contracts are often modified to account for changes in contract specifications and requirements. Contract modifications exist when the modification either creates new, or changes existing, enforceable rights and obligations. Generally, when contract modifications create new performance obligations, the modification is considered to be a separate contract and revenue is recognized prospectively. When contract modifications change existing performance obligations, the impact on the existing transaction price and measure of progress for the performance obligation to which it relates is generally recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.
Product revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Service revenue is generally recognized over time as the services are delivered to the customer based on the extent of progress towards completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. Depending on which better depicts the transfer of value to the customer, the Company generally measures its progress using either cost-to-cost (input method) or right-to-invoice (output method). The Company uses the cost-to-cost measure of progress when it best depicts the transfer of value to the customer which occurs as the Company incurs costs on its contract, generally related to fixed fee service contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. The costs calculation includes variables such as labor hours, allocation of overhead costs, research model costs, and subcontractor costs. Revenue is recorded proportionally as costs are incurred. The right-to-invoice measure of progress is generally related to rate per unit contracts, as the extent of progress towards completion is measured based on discrete service or time-based increments, such as samples tested or labor hours incurred. Revenue is recorded in the amount invoiced since that amount corresponds directly to the value of the Company’s performance to date.
The timing of revenue recognition, billings and cash collections results in billed receivables (client receivables), contract assets (unbilled revenue), and contract liabilities (current and long-term deferred revenue and customer contract deposits) on the consolidated balance sheets. The Company’s payment terms are generally 30 days in the United States and consistent with prevailing practice in international markets. A contract asset is recorded when a right to consideration in exchange for goods or services transferred to a customer is conditioned other than the passage of time. Client receivables are recorded separately from contract assets since only the passage of time is required before consideration is due. A contract liability is recorded when consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met. Cumulative catch-up adjustments to revenue are periodically recorded that affect the corresponding contract asset or contract liability, including adjustments arising from a change in the measure of progress, a change in an estimate of the transaction price (including any changes in the assessment of whether an estimate of variable consideration), or a contract modification.
Income Taxes
The provision for income taxes includes federal, state, local and foreign taxes. Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statements carrying amounts and their respective tax basis. The Company measures deferred tax assets and liabilities using the enacted tax rates in effect when the temporary differences are expected to be settled. The Company evaluates the realizability of its deferred tax assets and establishes a valuation allowance when it is more likely than not that all or a portion of deferred tax assets will not be realized.
The Company accounts for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The Company evaluates uncertain tax positions on a quarterly basis and considers various factors, including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, information obtained during in-process audit activities and changes in facts or circumstances related to a tax position. The Company also accrues for potential interest and penalties related to unrecognized tax benefits in income tax expense.
Foreign Currency Contracts
Foreign currency contracts are recorded at fair value in the Company’s consolidated balance sheets and are not designated as hedging instruments. Any gains or losses on forward contracts associated with intercompany loans are recognized immediately in Other (expense) income, net and are largely offset by the remeasurement of the underlying intercompany loan. Any gains or losses on forward contracts associated with the Company’s U.S. dollar denominated loan borrowed by a non-U.S. entity under the Company’s Credit Facility are recognized immediately in Interest expense. Gains or losses incurred on the remeasurement of the Company’s U.S. dollar denominated loan borrowed by a non-U.S. entity with a different functional currency is recorded in Other (expense) income, net.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Translation of Foreign Currencies
For the Company’s subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated at current rates of exchange as of the balance sheet date. Income and expense items are translated at the average foreign exchange rates for the period. Adjustments resulting from the translation of the financial statements of the Company’s foreign operations into U.S. dollars are excluded from the determination of net income and are recorded in accumulated other comprehensive loss, a separate component of equity.
Pension and Other Post-Retirement Benefit Plans
The Company recognizes the funded status of its defined benefit pension and other post-retirement benefit plans as an asset or liability. This amount is defined as the difference between the fair value of plan assets and the benefit obligation. The Company measures plan assets and benefit obligations as of its fiscal year end.
The key assumptions used to calculate benefit obligations and related pension costs include expected long-term rate of return on plan assets, withdrawal and mortality rates, expected rate of increase in employee compensation levels and a discount rate. Assumptions are determined based on the Company’s data and appropriate market indicators, and evaluated each year as of the plan’s measurement date.
The expected long-term rate of return on plan assets reflects the average rate of earnings expected on the funds invested, or to be invested, to provide for the benefits included in the projected benefit obligations. In determining the expected long-term rate of return on plan assets, the Company considers the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes and economic and other indicators of future performance.
The rate of compensation increase reflects the expected annual salary increases for the plan participants based on historical experience and the current employee compensation strategy.
The Company is required to recognize as a component of Other comprehensive income, net of tax, the actuarial gains or losses and prior service costs or credits that arise but were not previously required to be recognized as components of net periodic benefit cost. Other comprehensive income is adjusted as these amounts are later recognized in income as components of net periodic benefit cost.
The Company records the service cost component of the net periodic benefit cost within Cost of services provided and Selling, general, and administrative expenses and all other components of net periodic benefit cost within Other (expense) income, net in the consolidated statements of income.
The Company recognizes pension settlement gains or losses in the period when all of the following settlement criteria are met: there is an irrevocable action, the Company is relieved of primary responsibility for a benefit obligation, and significant risks related to the obligation and the assets used to effect the settlement are eliminated.
Earnings Per Share
Basic earnings per share is calculated by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding during the period. Except where the result would be anti-dilutive to income from continuing operations, diluted earnings per share is computed using the treasury stock method, assuming the exercise of stock options and the vesting of RSUs, or evaluating the performance conditions for PSUs to assess whether the conditions have been met, as well as their related income tax effects.
Treasury Shares
The Company periodically retires treasury shares acquired through share repurchases and returns those shares to the status of authorized but unissued. The Company accounts for treasury stock transactions under the cost method. For each reacquisition of common stock, the number of shares and the acquisition price for those shares is added to the existing treasury stock count and total value. Thus, the average cost per share is re-averaged each time shares are acquired. When treasury shares are retired, the Company allocates the excess of the repurchase price over the par value of shares acquired to both retained earnings and additional paid-in-capital. The portion allocated to additional paid-in-capital is determined by applying a percentage, determined by dividing the number of shares to be retired by the number of shares issued, to the balance of additional paid-in-capital as of the retirement date.

(1) The goodwill resulting from these transactions is primarily attributable to the potential growth of the Company’s segments from new customers introduced to the acquired businesses and the assembled workforce of the acquirees, thus is not deductible for tax purposes.
(2) In connection with its acquisitions of businesses, the Company routinely records liabilities related to indirect state and local taxes for preacquisition periods when such liabilities are estimable and deemed probable. The Company may or may not be indemnified for such indirect tax liabilities under terms of the acquisitions. As these indirect tax contingencies are resolved, actual obligations, and any indemnifications, may differ from the recorded amounts and any differences are reflected in reported results in the period in which these are resolved. Specifically for Cognate, as of March 29, 2021, the Company recorded an estimated liability of $17 million pertaining to indirect state sales taxes. During fiscal year 2022, the Company received a favorable ruling from the applicable state in which the indirect state sales tax liability arose and, accordingly, this liability was reduced in full, resulting in a gain recorded through selling, general and administrative expenses in the period.

The Company estimates the fair value of contingent consideration obligations through valuation models, such as probability-weighted and option pricing models, that incorporate probability adjusted assumptions and simulations related to the achievement of the milestones and the likelihood of making related payments. The unobservable inputs used in the fair value measurements include the probabilities of successful achievement of certain financial targets, forecasted results or targets, volatility, and discount rates. The remaining maximum potential payments are approximately $98 million, of which the value accrued as of December 30, 2023 is approximately $33 million. The weighted average probability of achieving the maximum target is approximately 34%. The average volatility and weighted average cost of capital are approximately 30% and 12%, respectively.
Cash Flow Hedge
The Company is exposed to market fluctuations in interest rates as well as variability in foreign exchange rates. In November 2022, the Company entered into an interest rate swap with a notional amount of $500 million to manage interest rate fluctuation related to floating rate borrowings under the Credit Facility, at a fixed rate of 4.700%.
In March 2023 and in conjunction with an amendment of the Credit Agreement (Second Amendment), the Company modified the variable rate on its interest rate swap from 1-month LIBOR to 1-month adjusted term SOFR. Effective with the modification, the Company will pay a fixed rate of 4.65% on its swap maturing November 2, 2024. The Company elected to apply the optional expedient in ASC 848, Reference Rate Reform, in connection with modifying its interest rate swap from LIBOR to SOFR that enabled it to consider the modification a continuation of the existing contract. As a result, the transition did not have an impact on the Company’s hedge accounting or a material impact to the Company’s financial statements.
Debt Instruments
The book value of the Company’s term and revolving loans, which are variable rate loans carried at amortized cost, approximates the fair value based on current market pricing of similar debt. As the fair value is based on significant other

The book value of the Company’s Senior Notes are fixed rate obligations carried at amortized cost. Fair value is based on quoted market prices as well as borrowing rates available to the Company. As the fair value is based on significant other observable outputs, it is deemed to be Level 2 within the fair value hierarchy.

(1) DSA includes accumulated impairment losses of $1 billion, which were recognized in fiscal years 2008 and 2010.
Based on the Company’s quantitative goodwill impairment test, which was performed in the fourth quarter for each of the fiscal years 2023, 2022 and 2021, the fair value of each reporting unit exceeded the reporting unit’s book value and, therefore, goodwill was not impaired. After completing the quantitative testing for fiscal year 2023, all reporting units exceeded the carrying value by a significant amount except for the Biologics Solutions reporting unit which had a fair value that exceeded its carrying value by approximately 20%.
The increase in goodwill during fiscal year 2023 related to the acquisitions of Noveprim and SAMDI in the DSA reportable segment. The increase in goodwill during fiscal year 2022 related to the acquisition of Explora in the RMS reportable segment, partially offset by a decrease due to the Avian divestiture impacting the Manufacturing reportable segment.

of debt extinguishment costs and $5 million of deferred financing costs write-offs were recorded in Interest expense during fiscal year 2021.
Revolving facility (Credit Facility)
The Company has a revolving credit facility “Credit Facility” that provides for up to $3.0 billion of multi-currency revolving credit. The Credit Facility has a maturity date of April 2026, with no required scheduled payment before that date. The interest rates applicable to the revolving facility are equal to (A) for revolving loans denominated in U.S. dollars, at the Company’s option, either the base rate (which is the higher of (1) the prime rate, (2) the federal funds rate plus 0.50%, or (3) the one-month adjusted SOFR rate plus 1.0%) or the adjusted SOFR rate, (B) for revolving loans denominated in euros, the adjusted EURIBOR rate and (C) for revolving loans denominated in sterling, the daily simple SONIA rate, in each case, plus an interest rate margin based upon the Company’s leverage ratio. In March 2023 and in conjunction with the Second Amendment the Company modified the variable rate on the Credit Facility from adjusted LIBOR to adjusted term SOFR. All outstanding U.S. dollar borrowings remained at adjusted LIBOR through their respective interest reset periods in April 2023 and were then set to term SOFR.
The Credit Facility includes certain customary representations and warranties, events of default, notices of material adverse changes to the Company’s business and negative and affirmative covenants. These covenants include (1) maintenance of a ratio of consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) less capital expenditures to consolidated cash interest expense, for any period of four consecutive fiscal quarters, of no less than 3.50 to 1.0 as well as (2) maintenance of a ratio of consolidated indebtedness to consolidated EBITDA for any period of four consecutive fiscal quarters, of no more than 4.25 to 1.0. As of December 30, 2023 and December 31, 2022, the Company was compliant with all financial covenants under the Credit Facility. The obligations of the Company under the Credit Facility are collateralized by substantially all of the assets of the Company.
2028 Senior Notes
In fiscal year 2019, the Company issued $500 million of 4.25% Senior Notes due in 2028 (2028 Senior Notes) in an unregistered offering. Interest on the 2028 Senior Notes is payable semi-annually on May 1 and November 1.
2029 Senior Notes and 2031 Senior Notes
In fiscal year 2021, the Company issued $1 billion of debt split between $500 million of 3.75% Senior Notes due in 2029 (2029 Senior Notes), and $500 million of 4.00% Senior Notes due in 2031 (2031 Senior Notes), in an unregistered offering. Interest on the 2029 and 2031 Senior Notes is payable semi-annually on March 15 and September 15. Approximately $10 million of deferred financing costs were capitalized as part of this debt issuance. Proceeds from the 2029 and 2031 Senior Notes were used as follows: prepay the $500 million 2026 Senior Notes, $21 million of debt extinguishment costs, and $13 million of accrued interest; prepay the $146.9 million remaining term loan; pay down $135 million of the revolving facility; and pay for a portion of the Cognate acquisition, which occurred on March 29, 2021.
Foreign currency transactions
During fiscal years 2022 and 2021, the Company had multiple U.S. dollar denominated loans borrowed by a non-U.S. Euro functional currency entity under the Credit Facility, which were between $250 million and $400 million each. To limit this foreign currency exposure, the Company entered into foreign exchange forward contracts, which are not designated as hedging instruments.

Treasury Shares
The Company’s Board of Directors has authorized a $1.3 billion stock repurchase program. As of December 30, 2023, the Company had $129.1 million remaining on the authorized stock repurchase program.
The Company’s stock-based compensation plans permit the netting of common stock upon vesting of RSUs and PSUs in order to satisfy individual statutory tax withholding requirements. The Company acquired shares of 0.1 million in fiscal years 2023 and 2022, for $24.2 million and $38.7 million, respectively, from such netting.
Prior to the end of fiscal years 2023, 2022 and 2021, the Company’s Board of Directors approved the cancellation and return to the Company’s authorized and unissued capital stock, reducing treasury stock on the Company’s consolidated balance sheet. The Company allocated the excess of the repurchase price over the par value of shares acquired to reduce both retained earnings and additional paid-in capital.

Nonredeemable Noncontrolling Interest
The Company has an investment in an entity whose financial results are consolidated in the Company’s financial statements, as it has the ability to exercise control over this entity. The interest of the noncontrolling party in this entity has been recorded as noncontrolling interest within Equity in the accompanying consolidated balance sheets. The activity within the nonredeemable noncontrolling interest (net income less dividends declared) during fiscal years 2023, 2022, and 2021 was not significant.
Redeemable Noncontrolling Interests
The Company holds a 90% ownership interest in Noveprim. The Company has the right to purchase, and the noncontrolling interest holders have the right to sell, the remaining 10% equity interest at a fixed redemption value that ranges from $47.0 million to $54.0 million depending on when exercised, which represents a derivative embedded within the equity instrument. The Company has the call option right to purchase the remaining 10% equity up until one month after the sixth anniversary of closing the 41% equity stake (December 2029). On the first anniversary of the expiration of the call option (December 2030), a 12-month put option will be triggered giving the seller the right to require the Company to acquire the remaining shares of the seller for $54.0 million. Additionally, the 10% noncontrolling interest holders may receive a dividend disproportionate to their equity ownership, which has an approximate fair value of $8 million. The redeemable noncontrolling interest is measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the accreted redemption value using the interest method and the carrying amount adjusted for net income (loss) attributable to the noncontrolling interest. As the noncontrolling interest holders have the ability to require the Company to purchase the remaining 10% interest, the noncontrolling interest is classified in the mezzanine section of the consolidated balance sheets, which is presented above the equity section and below liabilities.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The Company held a 92% ownership interest in Vital River, a commercial provider of research models and related services in China as of December 31, 2022. The Company had the right to purchase, and the noncontrolling interest holders had the right to sell, the remaining 8% equity interest at a contractually defined redemption value, subject to a redemption floor, which represents a derivative embedded within the equity instrument. The redeemable noncontrolling interest was measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the contractually defined redemption value and the carrying amount adjusted for net income (loss) attributable to the noncontrolling interest. The amount that the Company could be required to pay to purchase the remaining 8% equity interest was not limited. During the fourth quarter of fiscal 2023, the Company acquired the remaining 8% and as of December 2023, has paid $4.8 million of the total $24.4 million due. The remaining purchase price payable has been reclassified from the mezzanine section to Accrued liabilities on the consolidated balance sheet and is expected to be paid during fiscal year 2024.

In 2020, the Company acquired an 80% equity interest in a subsidiary, which included a 20% redeemable noncontrolling interest. In June 2022, the Company purchased an additional 10% interest in the subsidiary for $15.0 million, resulting in a remaining noncontrolling interest of 10%. Beginning in 2024, the Company has the right to purchase, and the noncontrolling interest holders have the right to sell, the remaining 10% equity interest at its appraised value. The redeemable noncontrolling interest is measured at the greater of the amount that would be paid if settlement occurred as of the balance sheet date based on the appraised value and the carrying amount adjusted for net income (loss) attributable to the noncontrolling interest ($11.0 million as of December 30, 2023) or a predetermined floor, which represents a derivative embedded within the equity instrument. The amount that the Company could be required to pay to purchase the remaining 10% equity interest is not limited.

Ending balance$22,702 $23,242 $32,592 
The $0.5 million decrease in unrecognized income tax benefits during fiscal year 2023 as compared to the corresponding period in 2022 is primarily attributable to prior year reductions to Canadian Scientific Research and Experimental Development (SR&ED) credits, partially offset by an additional year of SR&ED credit additions. The amount of unrecognized income tax benefits that, if recognized, would favorably impact the effective tax rate was $20.3 million as of December 30, 2023 and $20.3 million as of December 31, 2022. It is reasonably possible as of December 30, 2023 that the liability for unrecognized tax benefits for the uncertain tax position will decrease by approximately $5.2 million over the next twelve-month period. The Company continues to recognize interest and penalties related to unrecognized income tax benefits in income tax expense. The total amount of cumulative accrued interest related to unrecognized income tax benefits as of December 30, 2023 and December 31, 2022 was $1.3 million and $1.4 million, respectively. Interest expense recorded as a component of income taxes was immaterial for all periods. There were no accrued penalties related to unrecognized income tax benefits as of December 30, 2023 or as of December 31, 2022.
The Company conducts business in a number of tax jurisdictions. As a result, it is subject to tax audits on a regular basis including, but not limited to, such major jurisdictions as the U.S., the U.K., China, France, Germany, and Canada. With few exceptions, the Company is no longer subject to U.S. and international income tax examinations for years before 2019.
The Company and certain of its subsidiaries have ongoing tax controversies in the U.S., Canada, France, and India. The Company does not anticipate resolution of these audits will have a material impact on its consolidated financial statements.
Prepaid income tax of $59.7 million and $88.6 million has been presented within Other current assets in the accompanying consolidated balance sheets as of December 30, 2023 and December 31, 2022, respectively. Accrued income taxes of $38.8 million and $39.9 million have been presented within Other current liabilities in the accompanying consolidated balance sheets as of December 30, 2023 and December 31, 2022, respectively.
14. EMPLOYEE BENEFIT PLANS
Pension Plans
The Charles River Pension Plan (U.K. Pension Plan) is a defined contribution and defined benefit pension plan covering certain U.K. employees. Benefits are based on participants’ final pensionable salary and years of service. Participants’ rights vest immediately. The plan was previously amended to exclude new participants from joining the defined benefit section of the plan and a defined contribution section was established for new entrants. Contributions under the defined contribution plan are determined as a percentage of gross salary. Additionally, the U.K. Pension Plan was amended such that the members of the defined benefit section of the plan ceased to accrue additional benefits; however, their benefits continue to be adjusted for changes in their final pensionable salary or a specified inflation index, as applicable. During fiscal 2023, the Company made no contributions to the U.K. Pension Plan. As of fiscal 2023 year-end, this plan was in a funded status of $35.7 million.
During 2022, the Company terminated a non-contributory defined benefit plan that covered certain employees in Canada (Canada Pension Plan). Upon settlement of the pension liability in fiscal year 2022, the Company recognized a $1.0 million loss related to the net periodic benefit cost recorded in Other expense in the consolidated statements of income.
In addition, the Company has several defined benefit plans in certain other countries in which it maintains an operating presence, including Canada, France, Germany, Italy, Mauritius, Netherlands, and Japan.
The net periodic benefit cost (income) associated with these plans for fiscal years 2023, 2022 and 2021 totaled $2.8 million, $0.1 million and $0.5 million, respectively.

Charles River Laboratories Deferred Compensation Plan and Executive Supplemental Life Insurance Retirement Plan
The Company maintains a non-qualified deferred compensation plan, known as the Charles River Laboratories Deferred Compensation Plan (DCP), which allows a select group of eligible employees to defer a portion of their compensation. At the present time, no contributions are credited to the DCP, except as set forth below. Participants must specify the distribution date for deferred amounts at the time of deferral, in accordance with applicable IRS regulations. Generally, amounts may be paid in lump sum or installments upon retirement or termination of employment, or later if the employee terminates employment after age 55 and before age 65. Amounts may also be distributed during employment, subject to a minimum deferral requirement of three years.
The Company provides certain active employees an annual contribution into their DCP account of 10% of the employee’s base salary plus the lesser of their target annual bonus or actual annual bonus.
In addition to the DCP, certain officers and key employees also participate, or in the past participated, in the Company’s Executive Supplemental Life Insurance Retirement Plan (ESLIRP), which is a non-funded, non-qualified arrangement. Annual benefits under this plan will equal a percentage of the highest five consecutive years of compensation, offset by amounts payable under the U.S. Pension Plan and Social Security. In connection with the establishment of the DCP, certain active ESLIRP participants, who agreed to convert their accrued ESLIRP benefit to a comparable deferred compensation benefit, discontinued their direct participation in the ESLIRP. Instead, the present values of the accrued benefits of ESLIRP participants were credited to their DCP accounts, and future accruals are converted to present values and credited to their DCP accounts annually.
The net periodic benefit cost associated with these plans for fiscal years 2023, 2022 and 2021 totaled $2.8 million, $4.3 million and $4.3 million, respectively.
The Company has invested in several corporate-owned key-person life insurance policies with the intention of using these investments to fund the ESLIRP and the DCP. Participants have no interest in any such investments. As of December 30, 2023 and December 31, 2022, the cash surrender value of these life insurance policies were $48.4 million and $41.9 million, respectively.

In fiscal years 2023 and 2022, new mortality improvement scales were issued in the U.S. and the United Kingdom (U.K.) reflecting a decline in longevity projection from previous releases the Company adopted, which decreased the Company’s benefit obligations by $3.5 million and $0.2 million as of December 30, 2023 and December 31, 2022, respectively.
Plan Assets
The Company invests its pension assets with the objective of achieving a total long-term rate of return sufficient to fund future pension obligations and to minimize future pension contributions. The Company is willing to tolerate a commensurate level of risk to achieve this objective. The Company controls its risk by maintaining a diversified portfolio of asset classes. Plan assets did not include any of the Company’s common stock as of December 30, 2023 or December 31, 2022. The weighted-average target asset allocations are 7.0% to equity securities, 84.1% to fixed income securities and 8.9% to other securities.

Expected benefit payments are estimated using the same assumptions used in determining the Company’s benefit obligation as of 2023. Benefit payments will depend on future employment and compensation levels, among other factors, and changes in any of these factors could significantly affect these estimated future benefit payments. Estimated future benefit payments during the next five years and in the aggregate for fiscal years 2029 through 2033, are as follows.

Charles River Laboratories Employee Savings Plan
The Charles River Laboratories Employee Savings Plan is a defined contribution plan in the form of a qualified 401(k) plan in which substantially all U.S. employees are eligible to participate upon employment. The plan contains a provision whereby the Company matches a percentage of employee contributions. During fiscal years 2023, 2022 and 2021, the costs associated with this defined contribution plan totaled $31.6 million, $28.8 million and $24.0 million, respectively.
15. STOCK-BASED COMPENSATION
The Company has stock-based compensation plans under which employees and non-employee directors are granted stock-based awards such as stock options, RSUs, and PSUs.
During fiscal years 2023, 2022 and 2021, the primary share-based awards and their general terms and conditions are as follows:
Stock options, which entitle the holder to purchase a specified number of shares of common stock at an exercise price equal to the closing market price of common stock on the date of grant; typically vest over 4 years; and typically expire 5 or 10 years from date of grant.

CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
RSUs, which represent an unsecured promise to grant at no cost a set number of shares of common stock upon the completion of the vesting schedule, and principally vest over 4 years. With respect to RSUs, recipients are not entitled to cash dividends and have no voting rights on the stock during the vesting period.
PSUs, which entitle the holder to receive at no cost, a specified number of shares of common stock within a range of shares from zero to a specified maximum and typically vest over 3 years. Payout of this award is contingent upon achievement of certain performance and market conditions.
As of December 30, 2023, approximately 4.1 million shares were authorized for future grants under the Company’s share-based compensation plans. The Company settles employee share-based compensation awards with newly issued shares.

Performance Based Stock Award Program
The Company issues PSUs to certain corporate officers. The number of shares of common stock issued for each PSU is adjusted based on a performance condition linked to the Company’s financial performance. Certain awards are further adjusted based on a market condition, which is calculated based on the Company’s stock performance relative to a peer group over the three-year vesting period. The fair value of the market condition is reflected in the fair value of the award at grant date.
The Company utilizes a Monte Carlo simulation valuation model to value these awards. Information pertaining to the Company’s PSUs and the related estimated weighted-average assumptions used to calculate their fair value were as follows:

18. COMMITMENTS AND CONTINGENCIES
Insurance
The Company maintains certain insurance policies that maintain large deductibles up to approximately $2 million, some with or without stop-loss limits, depending on market availability. Insurance policies at certain locations are based on a percentage of the insured assets, for which deductibles for certain property may exceed $22.0 million in the event of a catastrophic event. In addition, the Company purchased representation and warranty insurance in support of some acquisitions, in which deductibles could reach $4.0 million.
Litigation
On February 16, 2023, the Company was informed by the U.S. Department of Justice (DOJ) that in conjunction with the U.S. Fish and Wildlife Service (USFWS), it had commenced an investigation into the Company’s conduct regarding several shipments of non-human primates from Cambodia. On February 17, 2023 the Company received a grand jury subpoena requesting certain documents related to such investigation. The Company is aware of a parallel civil investigation being undertaken by the DOJ and USFWS. The Company is cooperating with the DOJ and the USFWS and believes that the concerns raised with respect to the Company’s conduct are without merit. The Company maintains a global supplier onboarding and oversight program incorporating risk-based due diligence, auditing, and monitoring practices to help ensure the quality of our supplier relationships and compliance with applicable U.S. and international laws and regulations, and has operated under the belief that all shipments of non-human primates it received satisfied the material requirements, documentation and related processes and procedures of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) documentation and related processes and procedures, which guides the release of each import by USFWS. Notwithstanding our efforts and good-faith belief, in connection with the civil investigation, the Company has voluntarily suspended future shipments of non-human primates from Cambodia to the United States until such time that the Company and USFWS can agree upon and implement additional procedures to reasonably ensure that non-human primates imported from Cambodia are purpose-bred. The Company continues to care for the Cambodia-sourced non-human primates from certain recent shipments in the United States. The carrying value of the inventory related to these shipments is approximately $27 million as of December 30, 2023, which reflects the value of the shipments in accordance with the Company’s inventory accounting policy. On May 16, 2023, the Company received an inquiry from the Enforcement Division of the U.S. Securities and Exchange Commission (SEC) requesting it to voluntarily provide information, subsequently augmented with a document subpoena, primarily related to the sourcing of non-human primates, and the Company is cooperating with the request. We are not able to predict what action, if any, might be taken in the future by the DOJ, USFWS, SEC or other governmental authorities as a result of the investigations. None of the DOJ, USFWS or SEC has provided the Company with any specific timeline or indication as to when these investigations or, specific to the DOJ and USFWS, discussions regarding future processes and procedures, will be concluded or resolved. The Company cannot predict the timing, outcome or possible impact of the investigations, including without limitation any potential fines, penalties or liabilities.
A putative securities class action was filed on May 19, 2023 against the Company and a number of its current/former officers in the United States District Court for the District of Massachusetts. On August 31, 2023, the court appointed the State Teachers Retirement System of Ohio as lead plaintiff. An amended complaint was filed on November 14, 2023 that, among other things, included only James Foster, the Chief Executive Officer and David R. Smith, the former Chief Financial Officer as defendants along with the Company. The amended complaint asserts claims under §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 (the Exchange Act) on behalf of a putative class of purchasers of Company securities from May 5, 2020 through February 21, 2023, alleging that certain of the Company’s disclosures about its practices with respect to the importation of non-human primates made during the putative class period were materially false or misleading. The Company filed a motion to dismiss. While the Company cannot predict the outcome of this matter, it believes the class action to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.
On November 8, 2023, a stockholder filed a derivative lawsuit in the U.S. District Court of the District of Delaware asserting claims on the Company’s behalf against the members of the Company’s Board of Directors and certain of the Company’s current/former officers (James Foster, the Chief Executive Officer; David R. Smith, the former Chief Financial Officer; and Flavia Pease, the current Chief Financial Officer). The complaint alleges that the defendants breached their fiduciary duties to the Company and its stockholders because certain of the Company’s disclosures about its practices with respect to the importation of non-human primates were materially false or misleading. The complaint also alleges that the defendants breached their fiduciary duties by causing the Company to fail to maintain adequate internal controls over securities disclosure and compliance with applicable law and by failing to comply with the company’s Code of Business Conduct and Ethics. The Company intends to file a motion to dismiss. While the Company cannot predict the outcome of this matter, it believes the derivative lawsuit to be without merit and plans to vigorously defend against it. The Company cannot reasonably estimate the maximum potential exposure or the range of possible loss in association with this matter.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Aside from the matter above, the Company believes there are no other matters pending against the Company that could have a material impact on the Company’s business, financial condition, or results of operations.
Guarantees
The Company enters into certain agreements with other parties in the ordinary course of business that contain indemnification provisions. These typically include agreements with directors and officers, business partners, contractors, landlords, and customers. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. However, to date the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the estimated fair value of these obligations is minimal.
Purchase Obligations
The Company enters into unconditional purchase obligations, in the ordinary course of business, that include agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. These unconditional purchase obligations exclude agreements that are cancellable at any time without penalty. The aggregate amount of the Company’s unconditional purchase obligations totaled approximately $390 million as of December 30, 2023 and the majority of these obligations are expected to be settled during 2024.

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A.    Controls and Procedures
(a)   Evaluation of Disclosure Controls and Procedures
Based on their evaluation, required by paragraph (b) of Rules 13a-15 or 15d-15, promulgated by the Securities Exchange Act of 1934, as amended (Exchange Act), the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, are effective, at a reasonable assurance level, as of December 30, 2023, to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.
(b)   Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our assessment and those criteria, management concluded that the Company maintained effective internal control over financial reporting as of December 30, 2023.
Our assessment of the effectiveness of our internal control over financial reporting as of December 30, 2023 excluded Noveprim, which was acquired by the Company in 2023. Noveprim, whose total assets and total revenues were excluded from the Company’s assessment, represented approximately less than 1%, respectively, of the related consolidated amounts as of and for the fiscal year ended December 30, 2023.
The effectiveness of our internal control over financial reporting as of December 30, 2023, has been audited by PricewaterhouseCoopers LLP, an Independent Registered Public Accounting Firm, as stated in their report which appears in Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.
(c) Changes in Internal Controls Over Financial Reporting
During fiscal year 2023, there were no material changes in the Company’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of the Exchange Act Rules 13a-15 or 15d-15 that occurred during the fourth quarter of 2023 that materially affected, or were reasonably likely to materially affect, the Company’s internal control over financial reporting.

Our Insider Trading Policy is posted on our website and can be accessed by selecting the “Corporate Governance” link at http://ir.criver.com.
E.    Code of Ethics
We have adopted a Code of Business Conduct and Ethics that applies to all of our employees and directors, including our principal executive officer, principal financial officer, principal accounting officer, controller, or persons performing similar functions.

To obtain a copy, please mail a request to the Corporate Secretary, Charles River Laboratories International, Inc., 251 Ballardvale Street, Wilmington, MA 01887. Information on our website is not incorporated by reference in this annual report.
F.    Changes to Board Nomination Procedures
In December 2021, we amended our By-laws to include a proxy access by-law. Under our proxy access by-law, if a stockholder (or a group of up to 20 stockholders) who has owned at least 3% of our shares for at least three years and has complied with the other requirements set forth in our By-laws wants us to include director nominees (up to the greater of two nominees or 20% of the Board) in our proxy statement for an upcoming Annual Meeting, the nominations must be received in a timely manner, between 120 and 150 days prior to the anniversary of the date our proxy statement was first sent to stockholders in connection with the prior year’ annual meeting.
Item 11.    Executive Compensation
A.    Policies and Practices for Granting Certain Equity Awards.
The Compensation Committee of the Board of Directors is responsible for the review and approval of our policies and practices with respect to granting equity awards. The Compensation Committee typically targets the second quarter of our fiscal year, shortly after our annual meeting of shareholders and the release of our first quarter financial results, for granting annual stock awards to eligible recipients, absent an extraordinary event. The Compensation Committee believes this aligns timing of equity grants with the planning of annual salary increases (also in the second quarter of our fiscal year), allowing our managers to take a holistic view of total compensation.
The Compensation Committee seeks to structure equity grants so that they are awarded during an open window period as designated by our Insider Trading Policy, or, if Compensation Committee approval is provided during a non-window period, are typically made effective on the first business day following our press release with respect to financial results for the prior quarter. This policy is intended to ensure that options are awarded at a time when the exercise price fully reflects all recently disclosed information. In the case of new hires eligible to receive equity grants, grants are generally made on the first business day of the month following the date the individual commences employment.
105


CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
All grants to executive officers are made by the Compensation Committee itself and not pursuant to any delegated authority.
We have never had any programs, policies, or practices which are intended to time stock option grants with the release of material, non-public information in a manner that would provide advantageous option exercise prices to grant recipients. Option exercise prices are, in all cases, equal to the closing price of our common stock on the date of grant.
B.     Actions to Recover Erroneously Awarded Compensation
At no point during or after the last completed fiscal year did we prepare an accounting statement that required the recovery of erroneously awarded compensation pursuant to the company’s clawback policy, nor was there an outstanding balance as of the end of the last completed fiscal year of erroneously awarded compensation to be recovered from the application of the policy to a prior restatement.
The remainder of the information required by this Item will be included in the 2024 Proxy Statement under the sections captioned “2023 Director Compensation,” “Compensation Discussion and Analysis,” “Executive Compensation and Related Information,” “Compensation Committee Interlocks and Insider Participation” and “Report of Compensation Committee,” and is incorporated herein by reference thereto.

Originally adopted by the Board of Directors

Approved at Annual Meeting of Shareholders
On May 8, 2018
Amended by the Board of Directors
On March 14, 2020
Amendment and Restatement Approved at Annual Meeting of Shareholders
On May 6, 2020
Amended by the Administrator (the Compensation Committee of the Board of Directors)
On November 21, 2023


1.ADMINISTRATION
Subject to the express provisions of the Plan, the Administrator has the authority to interpret the Plan; determine eligibility for and grant Awards; determine, modify or waive the terms and conditions of any Award; prescribe forms, rules and procedures (which it may modify or waive); and otherwise do all things necessary to implement the Plan. Once an Award has been communicated in writing to a Participant, the Administrator may not, without the Participant’s consent, alter the terms of the Award so as to materially affect adversely the Participant’s rights under the Award, unless the Administrator has expressly reserved the right to do so or pursuant to Section 9.
2.LIMITS ON AWARDS UNDER THE PLAN
a.NUMBER OF SHARES. Subject to adjustments as provided in Section 5.b, the total number of shares of Stock subject to Awards granted under the Plan, in the aggregate, may not exceed 8,948,598 (the “Fungible Pool Limit”), which includes (A) a reserve of 439,798 shares of Stock remaining available for issuance under the 2016 Plan as in effect prior to the Original Effective Date and (B) an increase of 1,750,000 shares of Stock, as approved by the Board, subject to approval by the stockholders of the Company. Each share of Stock issued or to be issued in connection with any Full-Value Award shall be counted against the Fungible Pool Limit as 2.3 Fungible Pool Units. Stock Options, SARs and other Awards that do not deliver the full value at grant thereof of the underlying shares of Stock, that were granted prior to the Effective Date and that expire no more than seven (7) years from the date of grant, and such Stock Options, SARs and Other Awards that were granted on or after the Effective Date and that expire no more than ten (10) years from the date of grant, shall be counted against the Fungible Pool Limit as one (1.0) Fungible Pool Unit. (For these purposes, the number of shares of Stock taken into account with respect to a SAR shall be the number of shares of Stock underlying the SAR at grant (i.e., not the final number of shares of Stock delivered upon exercise of the SAR)). For purposes of the preceding sentence, shares that have been forfeited or cancelled in accordance with the terms of the applicable Award shall not be considered to have been delivered under the Plan, but shares held back in satisfaction of the exercise price or tax withholding requirements from shares that would otherwise have been delivered pursuant to an Award will be considered to have been delivered under the Plan. In addition, shares of Stock that have been repurchased by the Company with proceeds obtained in connection with the exercise of outstanding Awards shall not be added into the pool of available shares. Any shares of Stock that again become available for grant pursuant to this Section 2.a shall be added back to the pool of available shares. For purposes of clarity,

    Page 1 of 20    


in calculating the number of shares of Stock remaining under the Fungible Pool Limit, the Administrator will not increase the number of available Fungible Pool Units for shares of Stock delivered under an Award (i.e., previously acquired Shares tendered by the Participant in payment of the exercise price or of withholding taxes). The Administrator shall determine the appropriate methodology for calculating the number of shares of Stock issued pursuant to the Plan.
b.TYPE OF SHARES. Stock delivered by the Company under the Plan may be authorized but unissued Stock or previously issued Stock acquired by the Company and held in treasury. No fractional shares of Stock will be delivered under the Plan.
c.PARTICIPANT SHARE LIMIT. The maximum number of shares of Stock for which any Awards may be granted to any Participant annually from and after adoption of the Plan and prior to March 20, 2028 shall be 2,000,000, subject to adjustments as provided in Section 5.b. No Awards may be granted under the Plan after March 20, 2028, but previously granted Awards may extend beyond that date.
d.OTHER AWARD LIMITS. No more than $3,000,000 may be paid to any individual with respect to any Cash Performance Award (other than an Award expressed in terms of shares of Stock or units representing Stock, which shall instead be subject to the limit set forth in Section 2.c above). In applying the dollar limitation of the preceding sentence: (A) multiple Cash Performance Awards to the same individual that are determined by reference to performance periods of one year with or within the same fiscal year of the Company shall be subject in the aggregate to one limit of such amount, and (B) multiple Cash Performance Awards to the same individual that are determined by reference to one or more multiyear performance periods ending in the same fiscal year of the Company shall be subject in the aggregate to a separate limit of such amount.
e.NON-EMPLOYEE DIRECTOR LIMIT. The aggregate grant date fair value (determined as of the date of grant) of any Award granted under the Plan to an individual upon becoming a non-employee member of the Board of Directors (“Initial Non-Employee Director Grant”) shall not exceed $600,000. Subject to adjustment as provided in Section 5.b, no Participant who is a non-employee member of the Board of Directors may receive under the Plan (or otherwise) in any calendar year Stock Options, SARs, Restricted Stock, Unrestricted Stock, Deferred Stock and Performance Awards denominated in shares of Stock with a grant date fair value (determined as of the date of grant) that, when combined with the aggregate amount of any Cash Performance Awards and any other compensation granted to such Participant in such calendar year, exceeds an aggregate of $800,000 (excluding an Initial Non-Employee Director Grant).
f.ISO SHARE LIMIT. Subject to adjustments as provided in Section 5.b, the maximum number of shares of Stock available for issuance with respect to ISOs under the Plan shall be 3,500,000.
3.ELIGIBILITY AND PARTICIPATION
The Administrator will select Participants from among those key Employees, directors and other individuals or entities providing services to the Company or its Affiliates who, in the opinion of the Administrator, are in a position to make a significant contribution to the success of the Company and its Affiliates. Eligibility for ISOs is further limited to those individuals whose employment status would qualify them for the tax treatment described in Sections 421 and 422 of the Code.
4.RULES APPLICABLE TO AWARDS
a.ALL AWARDS
    Page 2 of 20    



(1)TERMS OF AWARDS. All Awards of Stock Options and SARs granted hereunder shall have a term of not to exceed ten (10) years from the date of grant; PROVIDED that such Awards granted hereunder prior to the Effective Date shall have a term not to exceed seven (7) years from the date of grant. The Administrator shall determine all other terms of all Awards subject to the limitations provided herein.
(2)PERFORMANCE CRITERIA. Where rights under an Award depend in whole or in part on satisfaction of Performance Criteria, actions by the Company that have an effect, however material, on such Performance Criteria or on the likelihood that they will be satisfied will not be deemed an amendment or alteration of the Award.
(3)ALTERNATIVE SETTLEMENT. The Company may at any time extinguish rights under an Award in exchange for payment in cash, Stock (subject to the limitations of Section 2) or other property on such terms as the Administrator determines, PROVIDED the holder of the Award consents to such exchange, PROVIDED FURTHER, no such exchange will be made where the cash, Stock or property to be received has a fair market value greater than the Award being extinguished, or where any such exchange would violate Section 4.a(9) of this Plan.
(4)TRANSFERABILITY OF AWARDS. Awards may not be transferred other than by will or by the laws of descent and distribution and during a Participant’s lifetime an Award requiring exercise may be exercised only by the Participant (or in the event of the Participant’s incapacity, the person or persons legally appointed to act on the Participant’s behalf).
(5)VESTING, ETC. Without limiting the generality of Section 1, the Administrator may determine the time or times at which an Award will vest (i.e., become free of forfeiture restrictions) or become exercisable and the terms on which an Award requiring exercise will remain exercisable. Notwithstanding anything contained herein to the contrary, (1) Awards that are not Performance Awards to Participants shall vest (i.e., become free of forfeiture restrictions) over a period of time at least three years or more from the date of grant and no Award shall vest in part or in whole before 12 months from the date of grant, and (2) Full-Value Awards that are Performance Awards shall be subject to the attainment of Performance Criteria which require at least 12 months to achieve and no Award shall vest in part or in whole before 12 months from the date of grant; PROVIDED, however, that Awards that aggregate not more than 5% of the number of shares reserved for issuance under the Plan may be awarded without the vesting requirements set forth in clauses (1) and (2).
Unless otherwise provided by Section 4.d with respect to Performance Awards or if the Administrator expressly provides otherwise:
(A)immediately upon the cessation of a Participant’s employment or other service relationship with the Company and its Affiliates, all Awards (other than Stock Options and SARs) held by the Participant (or by a permitted transferee under Section 4.a(4)) immediately prior to such cessation of employment or other service relationship will be forfeited if not then vested and, where exercisability is relevant, will cease to be exercisable;
(B)except as provided in clauses (C) and (D) below, all Stock Options and SARs held by a Participant (or by a permitted transferee under Section 4.a(4)) immediately prior to the cessation of the Participant’s employment or other service relationship for reasons other than Disability or death, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of three months or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 4.a(5), and shall thereupon terminate;
    Page 3 of 20    



(C)all Stock Options and SARs held by a Participant (or by a permitted transferee under Section 4.a(4)) immediately prior to the Participant’s Disability or death, to the extent then exercisable, will remain exercisable for the lesser of (i) the oneyear period ending with the first anniversary of the Participant’s Disability or death or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 4.a(5), and shall thereupon terminate; and
(D)all Stock Options and SARs held by a Participant (or by a permitted transferee of the Participant under Section 4.a(4)) whose cessation of employment or other service relationship is determined by the Administrator in its sole discretion to result from reasons which cast such discredit on the Participant as to justify immediate termination of the Award shall immediately terminate upon such cessation.
Unless the Administrator expressly provides otherwise, a Participant’s “employment or other service relationship with the Company and its Affiliates” will be deemed to have ceased, in the case of an employee Participant, upon termination of the Participant’s employment with the Company and its Affiliates (whether or not the Participant continues in the service of the Company or its Affiliates in some capacity other than that of an employee of the Company or its Affiliates), and in the case of any other Participant, when the service relationship in respect of which the Award was granted terminates (whether or not the Participant continues in the service of the Company or its Affiliates in some other capacity).
(6)TAXES. The Administrator will make such provision for the withholding of taxes as it deems necessary. The Administrator may, but need not, hold back shares of Stock from an Award or permit a Participant to tender previously owned shares of Stock in satisfaction of tax withholding requirements. For the avoidance of doubt, Stock may be tendered or held back by the Company in excess of the minimum amount required to be withheld for Federal, state, and local taxes.
As provided in Section 2.a of this Plan, in the event shares of Stock are held back from an Award in satisfaction of tax withholding requirements, such shares will nonetheless be considered to have been delivered under the Plan.
(7)DIVIDEND EQUIVALENTS, ETC. The Administrator may provide for the payment of amounts in lieu of cash dividends or other cash distributions with respect to Stock subject to any Full Value Award if and in such manner as it deems appropriate. Notwithstanding anything contained herein to the contrary, and without limiting the generality of Section 4.d(10), in no event shall an Award provide for any dividend or dividend equivalents to be payable to the Participant in respect of such Award prior to the time at which such Award (or the applicable portion thereof) vests (and, in the case of a Performance Award, the applicable performance condition is achieved).
(8)RIGHTS LIMITED. Nothing in the Plan shall be construed as giving any person the right to continued employment or service with the Company or its Affiliates, or any rights as a shareholder except as to shares of Stock actually issued under the Plan. The loss of existing or potential profit in Awards will not constitute an element of damages in the event of termination of employment or service for any reason, even if the termination is in violation of an obligation of the Company or Affiliate to the Participant. No Participant or other person shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Participants under the Plan. The terms and conditions of Awards need not be the same with respect to each recipient. Any Award granted under the Plan shall be a one-time Award that does not constitute a promise of future grants. Any Award granted under the Plan shall not be a part of a Participant’s base salary or wages and will not be taken into account in determining any other employment-related rights such Participant may have, such as rights to pension or severance pay. The Company, in its sole discretion, maintains the right to make available future
    Page 4 of 20    


grants under the Plan. Unless stated herein, no Participant or other person shall acquire any rights, remedies, benefits or obligations. Nothing contained in the Plan shall prevent the Company from adopting or continuing in effect other or additional compensation arrangements, and such arrangements may be either generally applicable or applicable only in specific cases. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other person. To the extent that any person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company.
(9)OPTION AND SAR REPRICING. Options and SARs may not be repriced, or replaced with any other award (including full-value awards), or repurchased for cash without the approval of the shareholders of the Company.
(10)FORFEITURE/CLAWBACK. The Committee may determine that any Award under this Plan shall be subject to provisions for the forfeiture and/or reimbursement of all amounts received in connection with an Award in the event of breach of noncompetition, nonsolicitation or confidentiality agreements. All Awards granted under this Plan are subject to recoupment, to the extent applicable, under the Company’s Corporate Governance Guidelines, as may be revised from time to time, and/or any other recoupment, clawback or similar policy that may be approved by the Board or any committee thereof. Notwithstanding any other provision of this Plan, a Participant shall be required to reimburse the Company amounts received in connection with an Award to the extent required under Section 304 of the Sarbanes-Oxley Act of 2002 and Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010.
(11)STOCK OWNERSHIP GUIDELINES/HOLDING PERIODS. The Committee may require that any Stock acquired by a Participant in connection with an Award granted under this Plan shall be subject to stock ownership guidelines, a minimum holding period or similar requirement under which a Participant shall not be permitted to transfer, sell, pledge, hedge, hypothecate or otherwise dispose of any such Stock.
b.AWARDS REQUIRING EXERCISE
(1)TIME AND MANNER OF EXERCISE. Unless the Administrator expressly provides otherwise, (a) an Award requiring exercise by the holder will not be deemed to have been exercised until the Administrator receives a written notice of exercise (in a form acceptable to the Administrator) signed by the appropriate person and accompanied by any payment required under the Award or adequate provision therefore, as set forth in Section 4.b(3); and (b) if the Award is exercised by any person other than the Participant, the Administrator may require satisfactory evidence that the person exercising the Award has the right to do so.
(2)EXERCISE PRICE. The Administrator shall determine the exercise price of each Stock Option and SAR; PROVIDED, that each Stock Option and SAR must have an exercise price that is not less than the fair market value of the Stock subject to the Stock Option and SAR, determined as of the date of grant. An ISO granted to an Employee described in Section 422(b)(6) of the Code must have an exercise price that is not less than 110% of such fair market value.
(3)PAYMENT OF EXERCISE PRICE, IF ANY. Where the exercise of an Award is to be accompanied by payment, the Administrator may determine the required or permitted forms of payment, subject to the following: (a) all payments will be by cash or check acceptable to the Administrator, or, if so permitted by the Administrator (with the consent of the optionee of an ISO if permitted after the grant), (i) through the
    Page 5 of 20    


delivery of shares of Stock which have been outstanding for at least six months (unless the Administrator approves a shorter period) and which have a fair market value equal to the exercise price, (ii) by delivery of a promissory note of the person exercising the Award to the Company, payable on such terms as are specified by the Administrator, (iii) if the Stock is publicly traded, by delivery of an unconditional and irrevocable undertaking by a broker to deliver promptly to the Company sufficient funds to pay the exercise price, (iv) or the withholding of shares of Stock from an Award, or (v) by any combination of the foregoing permissible forms of payment; and (b) where shares of Stock issued under an Award are part of an original issue of shares, the Award shall require an exercise price equal to at least the par value of such shares.
(4)GRANT OF STOCK OPTIONS. Each Stock Option awarded under the Plan shall be deemed to have been awarded as a nonISO (and to have been so designated by its terms) unless the Administrator expressly provides for ISO treatment that the Stock Option is to be treated as an ISO.
c.AWARDS NOT REQUIRING EXERCISE
Awards of Restricted Stock and Unrestricted Stock may be made in return for either (1) services determined by the Administrator to have a value not less than the par value of the Awarded shares of Stock, or (2) cash or other property having a value not less than the par value of the Awarded shares of Stock plus such additional amounts (if any) as the Administrator may determine payable in such combination and type of cash, other property (of any kind) or services as the Administrator may determine.
d.PERFORMANCE AWARDS
Performance Awards may be granted to Participants as follows:
(1)Prior to the grant of any Performance Award, the Administrator shall establish for each such award (i) performance levels at which 100% of the award shall be earned and a range (which need not be the same for all awards) within which greater and lesser percentages shall be earned and (ii) a performance period (which shall not be less than 12 months) which shall be determined at time of grant.
(2)With respect to the performance levels to be established pursuant to Section 4.d(1), the specific measures for each grant shall be established by the Administrator at the time of such grant. In creating these measures, the Administrator may establish the specific goals based upon or relating to any Performance Criteria (as defined below).
(3)Except as otherwise provided in Section 4.d(5), the percentage of each Performance Award to be distributed to an employee shall be determined by the Administrator on the basis of the performance levels established for such award and on the basis of individual performance in satisfaction of the Performance Award during such period. Any Performance Award, as determined and adjusted pursuant to this Section and Sections 4.d(5-8) is herein referred to as a “Final Award”. No distribution of any Final Award (or portion thereof) shall be made if the minimum performance level applicable to the related Performance Award is not achieved during the applicable performance period or, unless otherwise determined by the Administrator, if the employment of the employee to whom the related Performance Award was granted shall terminate for any reason whatsoever (including Disability and death) within 12 months after the date the Performance Award was granted.
(4)All Final Awards which have vested in accordance with the provisions of Sections 4.d.(5-10) shall be granted as soon as practicable following the end of the related vesting period. Final awards shall be
    Page 6 of 20    


granted in the form of Restricted Stock, Unrestricted Stock, Deferred Stock, Cash Performance Awards, or cash or any combination thereof, as the Administrator shall determine.
(5)Payment of any Final Award (or portion thereof) to an individual employee shall be subject to the continued rendering of services as an employee (unless this condition is waived by the Administrator). If the Administrator shall determine that such employee has failed to satisfy such conditions precedent, all Performance Awards granted to such employee which have not become Final Awards, and all Final Awards which have not been paid pursuant to Section 4.d(10) shall be immediately canceled. Upon termination of an employee’s employment other than by Disability or death (whether such termination is before or after a Performance Award shall have become a Final Award), the Administrator may, but shall not in any case be required to, waive the condition precedent of continuing to render services.
(6)If, upon termination of an employee’s employment prior to the end of any performance period for a reason other than Disability or death, the Administrator shall determine to waive the condition precedent of continuing to render services as provided in Section 4.d(5), the Performance Award granted to such employee with respect to such performance period shall be reduced pro rata based on the number of months remaining in the performance period after the month of such termination and such awards will be paid at the time they would have been paid absent an employment termination, unless otherwise determined by the Administrator or provided for in an award agreement. The Final Award for such employee shall be determined by the Administrator (i) on the basis of the performance levels established for such award (including the minimum performance level) and the performance level achieved through the end of the performance period and (ii) in the discretion of the Administrator, on the basis of individual performance during the period prior to such termination. A qualifying leave of absence, determined in accordance with procedures established by the Administrator, shall not be deemed to be a termination of employment but, except as otherwise determined by the Administrator, the employee’s Performance Award will be reduced pro rata based on the number of months during which such person was on such leave of absence during the performance period. A Performance Award shall not vest during a leave of absence granted an employee for local, state, provincial, or federal government service.
(7)Upon termination of an employee’s employment by reason of Disability or death prior to the end of any performance period, the Performance Award granted to such employee with respect to such performance period, except as otherwise provided in Section 4.d(3), shall be reduced pro rata based on the number of months remaining in the performance period after the month of such employee’s Disability or death. The percentage of the reduced Performance Award to be distributed to such employee shall be determined by the Administrator (i) on the basis of the performance levels established for such award (including the minimum performance level) and the performance level achieved through the end of the fiscal year during which such employee became Disabled or died and (ii) in the discretion of the Administrator, on the basis of individual performance during the applicable period. Such Final Awards will immediately vest and be paid as promptly as practicable.
(8)If an employee is promoted during the performance period with respect to any Performance Award, such Performance Award may, in the discretion of the Administrator, be increased to reflect such employee’s new responsibilities.
(9)Performance Awards that have become Final Awards may be subject to a vesting schedule established by the Administrator. Except as otherwise provided in this Plan, no Final Award (or portion thereof) subject to a vesting schedule shall be paid prior to vesting and the unpaid portion of any Final Award shall be subject to the provisions of Section 4.d(5). The Administrator shall have the authority to
    Page 7 of 20    


modify a vesting schedule as may be necessary or appropriate in order to implement the purposes of this Plan.
(10)No holder of a Performance Award shall have any rights to dividends or interest or other rights of a stockholder with respect to a Performance Award prior to such Performance Award’s becoming a Final Award.
(11)To the extent that any employee, former employee, or any other person acquires a right to receive payments or distributions under this Plan with respect to a Performance Award, such right shall be no greater than the right of a general unsecured creditor of the Company. All payments and distributions to be made hereunder shall be paid from the general assets of the Company. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company and any employee, former employee, or any other person.
5.EFFECT OF CERTAIN TRANSACTIONS
a.MERGERS, ETC. Other than in connection with Awards that are denominated and subject to settlement in cash, Awards shall not vest in connection with a Covered Transaction unless such Covered Transaction is accompanied by a “double trigger event”. For this purpose, a “double trigger event” occurs in connection with a Covered Transaction if (i) the Award is not appropriately assumed nor an equivalent award substituted by the surviving, continuing, successor or purchasing company or other business entity or parent thereof, as the case may be, (ii) cash or cash equivalents are the sole or primary form of consideration to be received by the shareholder of the Company and (iii) at the time of, or within 12 months following the Covered Transaction, the Participant incurs a termination of employment without Cause or for Good Reason.
Upon a Covered Transaction “double trigger event”: (i) in the case of a Stock Option or SAR, the Stock Option or SAR shall become fully vested and exercisable immediately upon the occurrence of the double trigger event; (ii) in the case of Restricted Stock, Deferred Stock or restricted stock units (in each case other than an award of Restricted Stock, award of Deferred Stock or award of restricted stock units that is a Performance Award), the restriction period shall lapse and the Restricted Stock, Deferred Stock or restricted stock unit (as applicable) shall fully vest immediately upon the occurrence of the double trigger event; and (iii) in the case of a Performance Award, payment under the Award shall be subject to the terms set forth in the applicable award agreement.
b.CHANGES IN AND DISTRIBUTIONS WITH RESPECT TO THE STOCK
(1)BASIC ADJUSTMENT PROVISIONS. In the event of a stock dividend, stock split or combination of shares, recapitalization or other change in the Company’s capital structure, the Administrator will make appropriate adjustments to the maximum number of shares that may be delivered under the Plan under Section 2.a and to the maximum share limits described in Section 2.c, and will also make appropriate adjustments to the number and kind of shares of stock or securities subject to Awards then outstanding or subsequently granted, any exercise prices relating to Awards and any other provision of Awards affected by such change.
(2)CERTAIN OTHER ADJUSTMENTS. The Administrator may also make adjustments of the type described in paragraph (1) above to take into account distributions to common stockholders other than those provided for in Section 5.a and 5.b (1), or any other event, if the Administrator determines that adjustments are appropriate to avoid distortion in the operation of the Plan and to preserve the value of Awards made hereunder; PROVIDED, that no such adjustment shall be made to the maximum share
    Page 8 of 20    


limits described in Section 2.c nor shall any change be made to ISOs except to the extent consistent with their continued qualification under Section 422 of the Code.
(3)CONTINUING APPLICATION OF PLAN TERMS. References in the Plan to shares of Stock shall be construed to include any stock or securities resulting from an adjustment pursuant to Section 5.b(1) or 5.b(2) above.
6.LEGAL CONDITIONS ON DELIVERY OF STOCK
The Company will not be obligated to deliver any shares of Stock pursuant to the Plan or to remove any restriction from shares of Stock previously delivered under the Plan until the Company’s counsel has approved all legal matters in connection with the issuance and delivery of such shares; if the outstanding Stock is at the time of delivery listed on any stock exchange or national market system, the shares to be delivered have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and all conditions of the Award have been satisfied or waived. If the sale of Stock has not been registered under the Securities Act of 1933, as amended, the Company may require, as a condition to exercise of the Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of such Act. The Company may require that certificates evidencing Stock issued under the Plan bear an appropriate legend reflecting any restriction on transfer applicable to such Stock.
7.AMENDMENT AND TERMINATION
The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by law, or may at any time terminate the Plan as to any further grants of Awards; PROVIDED, that (except to the extent expressly required or permitted by the Plan) no such amendment will, without the approval of the stockholders of the Company, effectuate a change for which stockholder approval is required under the rules of the New York Stock Exchange (which includes any “material revision” as defined under the rules of the New York Stock Exchange) or in order for the Plan to continue to qualify under Section 422 of the Code and to have an Award comply with, or avoid adverse consequences under, Section 409A of the Code.
8.NONLIMITATION OF THE COMPANY’S RIGHTS
The existence of the Plan or the grant of any Award shall not in any way affect the Company’s right to award a person bonuses or other compensation in addition to Awards under the Plan.
9.COMPLIANCE WITH APPLICABLE LAW
If any provision of the Plan or any applicable award agreement is or becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction, or as to any person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws, or if it cannot be so construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the applicable award agreement, such provision shall be stricken as to such jurisdiction, person or Award, and the remainder of the Plan and any such applicable award agreement shall remain in full force and effect.
10.DATA PRIVACY
The Company, any Affiliate and Committee may collect, process, transmit and store, in any
    Page 9 of 20    


form whatsoever, any data of a professional or personal nature described in the Plan, the applicable award agreement and any other grant or plan administration materials by and among, as applicable, the Company or any Affiliate that is necessary, in the discretion of the Company or any Affiliate, for the purposes of implementing, administering and managing the Participant’s participation in the Plan.

Notwithstanding any other provisions of the Plan rules, if, at the Grant Date, the total number of Stock granted subject to Awards made under the Plan and any other employee stock plan of the Company, where such Awards are granted subject to and in accordance with the provisions of Articles L.225-197-1 et seq. of the French Commercial Code and are, or are similar in substance to, a conditional right to acquire stock (other than an option) for no or limited cost (up to 5 percent of the fair market value of the stock), shall exceed 10 percent of the issued ordinary share capital of the issuing Company, Qualified Deferred Stock Awards may only be granted over such number of Stock as does not exceed a ratio of one to five between the smallest and largest awards of Qualified Deferred Stock Awards.
However, this relevant percentage is increased to 30 percent, if at the same time, awards are granted under the Plan, or awards are granted under any other stock plan of a Group Member, to all Eligible French Employees employed by a French Group Member or a French branch of a non-French Group Member.”

    Page 17 of 20    


7Dividend Equivalents
The first sentence of Section 4.a.(7) of the Plan is deleted in its entirety.
8Holding Period
A new Section 4.a.(12) is inserted immediately following Section 4.a.(11) of the Plan, as follows:

To the extent that a Qualified Deferred Stock Award vests less than two years after the Grant Date, the Stock acquired on vesting shall be subject to a Holding Period, so that there is a two-year period between the Grant Date and the date that the Stock may be freely disposed of by the French Participant, as required by Article L.225-197-1 of the French Commercial Code.
During the Holding Period, the Stock may be delivered to the French Participant, provided he shall agree not to sell, transfer, assign, mortgage, charge or otherwise dispose of the Stock (or any interest in them) during the Holding Period; or a nominee on behalf of the French Participant, provided that the beneficial ownership of the Stock vests in the French Participant and subject to a restriction on sale, transfer, assignment, mortgaging, charging or other disposal of such Stock (or any interest in them).”

“Notwithstanding any other provision of the Plan rules, the Plan shall, in no circumstances, have the effect of accelerating the Vesting Period or disapplying the Holding Period in circumstances where there would be a less than two year period between the Grant Date and the date that the Stock may be freely disposed of by the French Participant, except in the two following cases:
- Death of the French Participant
If a French Participant dies before his Qualified Deferred Stock Award has vested, his Qualified Deferred Stock Award shall vest immediately and any applicable Holding Period will fall away. The Qualified Deferred Stock Award may only be adjusted in such proportion as determined by the Administrator in its absolute discretion after taking into account the Performance Criteria. The Qualified Deferred Stock Award cannot be adjusted for any other criteria e.g. for time. The heirs of the deceased French Participant can require the vesting within six months from the date of death, as provided by the article L225-197-3 of the French commercial code.

    Page 18 of 20    


Where, after a Qualified Deferred Stock Award has vested but before the expiry of any applicable Holding Period, the French Participant dies, his Stock shall cease to be subject to the Holding Period.
- Disability of the French Participant
Notwithstanding any other provision of the Plan rules, if a French Participant ceases to be in employment due to Disability before his Qualified Deferred Stock Award has vested all or a proportion of his Qualified Deferred Stock Award may vest immediately, in such proportion as determined by the Administrator in its absolute discretion, having regard to the satisfaction of the Performance Criteria and any other condition as at the time of cessation of employment, and such other factors as the Administrator may consider relevant. If a French Participant ceases to be in employment due to Disability before his Qualified Deferred Stock Award has vested, the Holding Period shall fall away.
If the French Participant ceases to be in employment due to Disability after the vesting but before the expiry of any applicable Holding Period, his Stock shall cease to be subject to the Holding Period on the date of cessation of his employment.”
11Effect of certain transactions
The following wording is inserted immediately following the end of the Sections 5.a of the Plan, as follows:
To the extent that the Administrator intends for the Qualified Deferred Stock Awards to retain favorable tax and social security treatment under this French Schedule, Sections 5.a and 5.b shall apply to Qualified Deferred Stock Awards in accordance with the provisions of Articles L. 225-197-1-III of the French Commercial Code and 80 quaterdecies of the French Tax Code, and shall be modified or interpreted in order to comply with these provisions.”
The following wording is inserted immediately following the end of the Section 5.b of the Plan, as follows:
“If the share capital of the Company is modified during the Vesting Period or Holding Period, the Qualified Deferred Stock Awards may be adjusted as appropriate to ensure that there is no impact on the French Participants’ Qualified Deferred Stock Awards, provided that such adjustment has the sole purpose and effect of preserving the value of Qualified Deferred Stock Awards and that additional Stock which could be issued as a result remains subject to the same requirements (including the vesting and holding requirements) as those applying to the original Qualified Deferred Stock Award”.
12Taxes
A new rule is inserted immediately following the end of Section 4.a.(6) of the Plan, as follows:
“The preceding paragraph does not apply to Qualified Deferred Stock Awards. A French Participant is responsible for paying any relevant taxes and reporting the receipt of any income under the French Schedule, however made, to the relevant tax authority”.
13Amendment and termination
The following wording is inserted immediately following the end of the Section 7 of the Plan, as follows:
Except as permitted in this Section 7, an amendment to the provisions of the Plan may only be applied to Qualified Deferred Stock Awards already granted to the extent that:

    Page 19 of 20    


-the proposed change does not affect the qualifying status of the Qualified Deferred Stock Awards for French tax and social security purposes; and
-if the change would adversely affect the existing rights of the French Participants, affected French Participants’ prior consent is obtained.
14Cross references
Unless specified otherwise, where a deletion, addition or amendment is made to the rules by this French Schedule, other references throughout the rules and this French Schedule to those additional, amended or deleted Rules (as appropriate) are deemed to be included, modified or deleted accordingly.
15Conclusion
The following paragraphs are inserted immediately following Section 11 in the Plan, as follows:
It is intended that Deferred Stock awards granted to Eligible French Employees shall qualify for the special tax and social security treatment applicable to free shares granted under articles L. 225-197-1 to L.225-197-6 of the French Commercial Code and in accordance with the relevant provisions set forth by the French tax and social security laws (article 80 quaterdecies of the French Tax Code and article L.242-1 of the French Social security Code). Accordingly, the rules, the terms of the French Schedule and the terms upon which a Deferred Stock award has been granted shall be interpreted and, where necessary, deemed to be modified, in accordance with the relevant provisions set forth by French laws, as well as the relevant administrative provisions.
If for any reason a Deferred Stock award does not satisfy the requirements of the French tax authorities for favorable income tax and social security treatment, and therefore does not qualify as a Qualified Deferred Stock Award, the Company or Administrator can take such actions, including (but not limited to) changing the Vesting Period and/or the Holding Period of the Deferred Stock award, as it considers reasonably necessary to achieve such treatment, and the rules, the terms of the French Schedule and the terms of the Qualified Deferred Stock Award shall be interpreted and, where necessary, modified accordingly. The Company and any Group Member shall not be liable for any adverse consequences, legal, tax or otherwise, if and to the extent that Deferred Stock awards do not qualify as Qualified Deferred Stock Awards.”

“Retirement Eligible” means that you (i) have attained age 55, (ii) have a minimum of 10 years of service with the Company and its subsidiaries and/or affiliates (such service only to have deemed to have commenced at such time as such subsidiary and/or affiliate became a subsidiary and/or affiliate of the Company, (iii) the numerical sum of your age and years of service (as calculated pursuant to clause (ii) above) is equal to at least 70, (iv) you have given notice, in form satisfactory to the Company, to the Chief People Officer of the Company (or, if you are the Chief People Officer, to the Chief Executive Officer) of your intent to retire specifying the exact intended date of retirement to the Company (provided that prior to such notice the Company had not already given you notice that you would be terminated), and remained employed by the Company until the earlier of (a) the one year anniversary of the date of such notice or (b) the date on which you experience a termination of employment due to death or disability or you are terminated by the Company without cause and (v) at the time you give such notice to the Company you also provide the Company with a signed acknowledgement, in a form satisfactory to the Company, reaffirming the covenants set forth below in “Retirement Restrictions”; provided, however, in the case of (b), the employee’s age and years of service



shall be calculated as if the employee was employed through the one-year anniversary of the date of such notice.

Retirement Restrictions

For the period beginning on the date of your Full Career Retirement and ending on the date on which the restricted unit would have become fully vested absent a termination of employment (the “Restricted Period”), you shall not, directly or indirectly, without the prior written consent of the Company,
(1)render services as an employee, consultant, director, partner or otherwise to any person, entity, division, subsidiary or subgroup whose primary business activity is in competition with the Company’s business, or
(2)assist with the creation of (a) any entity whose primary business activity is in competition with the Company’s business, or (b) any division, subsidiary or subgroup of an entity whose primary business activity is in competition with the Company’s business. Nothing herein shall prohibit you from pursuing employment with any corporation or entity engaged substantially in the discovery or development of pharmaceuticals or medical devices as long as such company also manufactures, markets and sells such products.

YOU ACKNOWLEDGE AND UNDERSTAND THAT THIS SECTION MAY AFFECT YOUR RIGHT TO ACCEPT EMPLOYMENT WITH OTHER COMPANIES SUBSEQUENT TO EMPLOYMENT BY THE COMPANY AND THAT THE RESTRICTIONS CONTAINED HEREIN ARE SEPARATE AND APART AND IN ADDITION TO ANY SIMILAR RESTRICTIONS, NON-COMPETE OR OTHERWISE, THAT YOU MAY BE SUBJECT TO PURSUANT ANY OTHER AGREEMENT WITH THE COMPANY OR ANY OF ITS AFFILIATES.

Shares

Upon the vesting of your RSUs, the underlying shares which have vested will be transferred from the transfer agent to your stock account at CRL’s stock plan administrator.

Withholding Taxes

No shares will be released to you unless you have made acceptable arrangements to pay any withholding taxes that may be due as a result of the receipt of Shares upon vesting of the RSUs that you receive under this Award. These arrangements may include withholding of Shares that otherwise would be released to you when the RSUs vest or surrendering of RSUs or shares that you already own. The Fair Market Value of RSUs or Shares that are withheld or that you surrender, determined as of the date when the taxes otherwise would have been withheld in cash, will be applied as a credit against the taxes.

Lock-Up Period

If requested by the Company, you hereby agree that you will not sell, transfer, pledge, otherwise dispose, make any short sale of, grant any option for the purchase of or enter into any hedging or similar transaction with the same economic effect as a sale, any Shares (or other securities of the Company) held by you (other than those included in the registration) for a period specified by the representative of the underwriters of the Common Stock (or other securities of the Company) not to exceed 180 days following the effective date of a registration statement of the Company filed under the Securities Act.

You agree to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, you will provide, within 10 days of the request, the information required by the Company or the

The obligations described in this section entitled “Lock-Up Period” will not apply to a registration relating solely to employee benefit plans on Form S-3 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the Shares (or other securities) subject to the foregoing restriction until the end of the 180-day period.

Recoupment

Shares awarded under this Award Agreement are subject to recoupment in accordance with the Company’s Corporate Governance Guidelines, as may be revised from time to time, and/or any other so-called recoupment, clawback or similar policy that may be approved by the Board of Directors of the Company or any committee thereof.

The Company may, in its sole discretion and without your consent, modify or amend the terms of this Award Agreement, impose conditions on



the timing and effectiveness of the issuance of the Restricted Stock Units, and/or take any other action it deems
necessary to cause this Award Agreement to be exempted from Section 409A (or to comply therewith to the extent the Company determines it is not excepted). Notwithstanding, you recognize and acknowledge that Section 409A may affect the timing and recognition of payments due hereunder, and may impose upon you certain taxes or other charges for which you are and shall remain solely responsible.

Title: Insider Trading Policy


PURPOSE

It is the policy of Charles River Laboratories International, Inc., its subsidiaries, and affiliates (together, the “Company” or “Charles River”) that it will comply with all applicable laws and regulations in conducting its business, without exception. All employees, directors, and officers of the Company are expected to abide by this policy. When carrying out Company business, employees, officers, and directors must avoid any activity that violates applicable laws or regulations. To avoid even an appearance of impropriety, the Company’s directors, officers, and certain other employees are subject to pre-approval requirements and other limitations on their ability to enter into transactions involving the Company’s securities. Although these limitations do not apply to transactions pursuant to written plans for trading securities that comply with Rule 10b5-1 (“Rule 10b5-1 Plan”) promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”), the entry into amendment or termination of any such written trading plan is subject to pre-approval requirements and other limitations, as described below
SCOPE
This policy applies to all directors, officers, and employees of Charles River Laboratories International, Inc. (and its affiliates and subsidiaries), and to other people who gain access to that information. The prohibition applies to both domestic and international employees of the Company and its subsidiaries. Because of their access to confidential information on a regular basis, Company policy subjects its directors, corporate officers, employees at the level of Vice President or higher, and certain other employees (the “Window Group”) to additional restrictions on trading in the Company securities. The restrictions for the Window Group are discussed in the Guidelines section below. In addition, directors and certain employees with inside knowledge of material information may be subject to ad hoc restrictions on trading from time to time, as discussed in in the Event- Specific Trading Restriction Periods section below.

Title: Insider Trading Policy


General Rule
The U.S. securities laws regulate the sale and purchase of securities in the interest of protecting the investing public. U.S. securities laws give the Company, its officers and directors, and other employees the responsibility to ensure that information about the Company is not used unlawfully in the purchase and sale of securities.
All employees, officers, and directors should pay particularly close attention to the laws against trading on “inside” information. These laws are based upon the belief that all persons trading in a company’s securities should have equal access to all “material” information about that company. For example, if an employee, director, or officer of a company knows material non-public financial information, the individual is prohibited from buying or selling stock in the company until the information has been disclosed to the public. This is because the employee, director, or officer knows information that will probably cause the stock price to change, and it would be unfair for the employee, director, or officer to have an advantage (knowledge that the stock price will change) that the rest of the investing public does not have. In fact, it is more than unfair. It is considered to be fraudulent and illegal. Civil and criminal penalties for this kind of activity are severe.
The general rule can be stated as follows: It is a violation of the U.S. federal securities laws for any person to buy or sell securities if he or she is in possession of material inside information. Information is material if there is a substantial likelihood that a reasonable investor would consider it important in making an investment decision. It is inside information if it has not been publicly disclosed in a manner making it available to investors generally on a broad-based non-exclusionary basis. Furthermore, it is illegal for any person in possession of material inside information to provide other people with such information or to recommend that they buy or sell the securities. (This is called “tipping”.) In that case, they may both be held liable.

The Securities and Exchange Commission (the “SEC”), the stock exchanges, and plaintiffs’ lawyers focus on uncovering insider trading. A breach of the insider trading laws could expose the insider to criminal fines per violation up to $5 million and imprisonment up to twenty years, in addition to civil penalties (up to three times the profits earned), and injunctive actions. In addition, punitive damages may be imposed under applicable state laws. Securities laws also subject controlling persons to civil penalties for illegal insider trading by employees, including employees located outside the United States. Controlling persons include directors, officers, and supervisors. These persons may be subject to fines up to the greater of $1 million-or three-times profit (or loss avoided) by the insider trader.

Inside information does not belong to the individual directors, officers, or other employees who may handle it or otherwise become knowledgeable about it. It is an asset of the Company. For any person to use such information for personal benefit or to disclose it to others outside the Company violates the Company’s interests. More particularly, in connection with trading in the Company securities, it is a fraud against members of the investing public and against the Company.

Title: Insider Trading Policy


Employees, officers, and directors who learn material information about suppliers, customers, or competitors through their work at the Company should keep it confidential and not buy or sell stock in such companies until the information becomes public. Employees, officers, and directors should not give tips about such stocks.

Trading in Options

The insider trading prohibition also applies to trading in options, such as put and call options. Options trading is highly speculative and very risky. People who buy options are betting that the stock price will move rapidly. For that reason, when a person trades in options in his or her employer’s stock, it will arouse suspicion in the eyes of the SEC that the person was trading on the basis of inside information, particularly when the trading occurs before a Company announcement or major event. It is difficult for an employee, officer, or director to prove that he or she did not know about the announcement or event.

If the SEC or the stock exchanges were to notice active options trading by one or more employees, officers, or directors of the Company prior to an announcement, they would investigate. Such an investigation could be embarrassing to the Company (as well as expensive) and could result in severe penalties and expense for the persons involved. For all of these reasons, the Company prohibits its employees, officers, and directors from trading in options on the Company stock. This policy does not pertain to employee stock options granted by the Company, such as employee or director compensatory stock options (“employee stock options”) which cannot be traded to any extent.


Margin Accounts and Pledged Securities

Securities held in a margin account may be sold by the broker without the customer’s consent if the customer fails to meet a margin call. Similarly, securities pledged (or hypothecated) as collateral for a loan may be sold in foreclosure if the borrower defaults on the loan. Because such a sale or foreclosure sale may occur at a time when an employee, director, or officer has material inside information or is otherwise not permitted to trade in Company securities, the Company prohibits employees, officers and directors from purchasing Company securities on margin or holding Company securities in a margin account or otherwise pledging Company securities as collateral for a loan. (Pledges of Company securities arising from certain types of hedging transactions are governed by the paragraph below entitled “Hedging Transactions.”)

Hedging Transactions

Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds. Such hedging transactions may permit an employee, director, or officer to continue to own Company securities obtained through employee benefit plans or otherwise, but without the full risks and

rewards of ownership. When that occurs, the employee, director, or officer may no longer have the same objectives as the Company’s other shareholders. Therefore, the employee, director, or officer is prohibited from engaging in any such transactions.

Guidelines

The following guidelines should be followed in order to ensure compliance with applicable antifraud laws and
with the Company’s policies:

1.Nondisclosure. Material inside information must not be disclosed to anyone, except to persons within the Company whose positions require them to know it.

2.Trading in the Company’s Securities. No employee, director, or officer should place a purchase or sale order or recommend that another person place a purchase or sale order in the Company’s securities, when he or she has knowledge of material information concerning the Company that has not been disclosed to the public. This includes orders for purchases and sales of stock and convertible securities. The exercise of employee stock options is not subject to this policy. However, stock that was acquired upon exercise of a stock option will be treated like any other stock, and may not be sold by an employee, officer, or director who is in possession of material inside information; accordingly, stock options may not be exercised pursuant to a net exercise program involving a broker or other third party and that is designed to cover the exercise price, withholding tax, and other related costs.

3.Avoid Speculation. Investing in the Company’s Common Stock provides an opportunity to share in the future growth of the Company. But investment in the Company and sharing in the growth of the Company does not mean short range speculation based on fluctuations in the market. Such activities put the personal gain of the employee, officer, or director in conflict with the best interests of the Company and its stockholders. Although this policy does not mean that employees, officers, or directors may never sell shares, the Company encourages employees and directors to avoid frequent trading in Company stock. Speculating in Company stock is not part of the Charles River culture.

4.Trading in Other Securities. No employee, director, or officer should place a purchase or sale order, or recommend that another person place a purchase or sale order, in the securities of another corporation if the employee, director, or officer learns during his or her employment confidential information about the other corporation that is likely to affect the value of those securities. For example, it would be a violation of the securities laws if an employee, officer, or director learned through Company sources that the Company intended to purchase assets from a company, and then bought or sold stock in that other company because of the likely increase or decrease in the value of its securities.

5.Employee Stock Purchase Plan. Employees are permitted to purchase Company Common Stock pursuant to the Employee Stock Purchase Plan (ESPP) provided that the election to participate in the ESPP is made when not in possession of material inside information or, for members of the Window

Group (as defined below), during a Window (as defined below).

6.Restrictions on the Window Group. The Window Group consists of (a) directors and executive officers of the Company and their executive assistants, (b) officers and other employees of the Company with the title Vice President or higher and their executive assistants, and (c) such other persons as may be designated from time to time and informed of such status by the Company’s Office of the General Counsel. The Window Group also applies to such individual’s household members. The Window Group is subject to the following restrictions on trading in Company securities:
any transactions involving Company securities, including bona fide gifts of Company securities by members of the Window group, (collectively, “trades”) are only permitted from the start of the first business day following an earnings release with respect to the preceding fiscal period until two weeks after the end of the second fiscal month of the then-current fiscal quarter (the “Window”), subject to the additional restrictions below;
all trades are subject to prior review;
clearance for all trades should be obtained from the Company’s Office of the General Counsel
(clearance will be given for no longer than three business days in advance of any trade);
no trading outside the Window except for reasons of exceptional personal hardship and subject to prior review by the Office of the General Counsel or a legal department delegate; and
individuals in the Window Group are also subject to the general restrictions on all employees.
Note that at times the Office of the General Counsel may determine that no trades may occur even during the Window when clearance is requested. In some cases, a reason may not be provided, and the closing of the Window itself may constitute material inside information that should not be communicated.
The foregoing Window Group restrictions do not apply to transactions pursuant to written plans for trading securities that comply with 10b5-1 Plans. However, Window Group members may not enter into, amend, or terminate a 10b5-1 Plan relating to Company securities without the prior approval of the Office of the General Counsel, which, in most cases, will only be given during a Window period. Additionally, Window Group members are permitted to enter into a 10b5-1 Plan only if such plan is entered into in good faith and in compliance with the provisions of Rule 10b5-1.

Applicability of U.S. Securities Laws to International Transactions

All employees of the Company’s subsidiaries are subject to the restrictions on trading in the Company securities and the securities of other companies. The U.S. securities laws may be applicable to the securities of the Company’s subsidiaries or affiliates, even if they are located outside the United States. Transactions involving securities of subsidiaries or affiliates should be carefully reviewed by counsel for compliance not only with local law but also for possible application of U.S. securities laws.

Event-Specific Trading Restriction Periods

From time to time, an event may occur that is material to the Company and is known by only a few directors, officers, and/or employees. So long as the event remains material and nonpublic, the persons designated by the Office of the General Counsel may not trade Company securities. In addition, the Company’s financial results may be sufficiently material in a particular fiscal quarter that, in the judgment of the Office of the General Counsel, designated persons should refrain from trading in Company securities even sooner than the typical end of the Window. In that situation, the Office of the General Counsel may notify these persons that they should not trade in the Company’s securities, without disclosing the reason for the restriction. The existence of an event-specific trading restriction period or reduction of a Window will not be announced to the Company as a whole and should not be communicated to any other person. Even if the Office of the General Counsel has not designated an individual as a person who should not trade due to an event-specific restriction, in no event should anyone trade while aware of material nonpublic information.

OTHER LIMITATIONS ON SECURITIES TRANSACTIONS

Public Resales - Rule 144

The Securities Act of 1933 (“1933 Act”) requires every person who offers or sells a security to register such transaction with the SEC unless an exemption from registration is available. Rule 144 under the 1933 Act is the exemption typically relied upon (a) for public resales by any person of “restricted securities” (i.e., securities acquired in a private offering or sale, excluding certain private issuances outside the United States) and (b) for public resales by directors, officers, and other controlling persons of a company (known as “affiliates”) of any of the Company’s securities, whether restricted or unrestricted.

Rule 144 contains a number of conditions, although the applicability of some of these conditions will depend on the circumstances of the sale:
1.Current Public Information. Current information about the Company must be publicly available before the sale can be made. The Company’s periodic reports filed with the SEC ordinarily satisfy this requirement. If the seller is not (and has not been for at least three months) an affiliate of the company issuing the securities and one year has passed since the securities were acquired from the issuer or an affiliate of the issuer (whichever is later), the seller can sell the securities without regard to the current public information requirement.
2.Holding Period. Restricted securities must be held and fully paid for by the seller for a period of at

least six months prior to the sale. The holding period requirement, however, does not apply to securities held by affiliates that were acquired either in the open market or in a public offering of securities registered under the 1933 Act. If the seller acquired the securities from someone other than the Company or an affiliate of the Company, the holding period of the person from whom the seller acquired such securities can be “tacked” to the seller’s holding period in determining if the holding period has been satisfied.
Rule 144 also imposes the following additional conditions on sales by persons who are affiliates or who have been affiliates during the previous three months:
1.Volume Limitations. The amount of equity securities which can be sold during any three- month period cannot exceed the greater of (a) one percent of the outstanding shares of the class or (b) the average weekly reported trading volume for shares of the class during the four calendar weeks preceding the filing of the notice of sale referred to below. The amount of debt securities which can be sold by an affiliate during any three-month period cannot exceed ten percent of a tranche (or class when the securities are non-participatory preferred stock), together with all sales of securities of the same tranche sold for the account of the affiliate within a three-month period.
2.Manner of Sale. Equity securities must be sold in unsolicited brokers’ transactions, directly to a
market-maker or in riskless principal transactions.

3.Notice of Sale. The seller must file a notice of the proposed sale with the SEC at the time the order to sell is placed with the broker, unless the amount to be sold neither exceeds 5,000 shares nor involves sale proceeds greater than $50,000. See the Filing Requirements section below.
Bona fide gifts are not deemed to involve sales of stock for purposes of Rule 144, so they can be made at any time without limitation on the amount of the gift. Donees who receive restricted securities from an affiliate generally will be subject to the same restrictions under Rule 144 that would have applied to the donor for a period of up to two years following the gift, depending on the circumstances.

Private Resales
Directors and officers also may sell securities in a private transaction without registration. Although there is no statutory provision or SEC rule expressly dealing with private sales, the general view is that such sales can safely be made by affiliates if the party acquiring the securities is sophisticated and understands he or she is acquiring restricted securities that must be held for at least one year before the securities will be eligible for resale to the public under Rule 144. Private resales raise certain documentation requirements and other issues and must be reviewed in advance by the Company’s Office of the General Counsel.

Restrictions on Purchases of Company Securities
In order to prevent market manipulation, the SEC has adopted Regulation M under the 1934 Act. Regulation M generally prohibits the Company or any of its affiliates from buying Company stock during certain periods while a distribution is taking place. These rules set forth guidelines for purchases of Company stock by the

Company or its affiliates while a stock buyback program is occurring. Affiliates should consult with the Company’s Office of the General Counsel if they desire to make purchases of Company stock during any period that the Company is making a distribution or buying stock from the public.

Disgorgement of Profits on Short-Swing Transactions Under Section 16(b)
Section 16 of the 1934 Act applies to directors and certain executive officers of the Company and to any person owning more than ten percent of any registered class of the Company’s equity securities. The section is intended to deter such persons (collectively referred to below as “Section 16 Insiders”) from misusing confidential information about their companies for personal trading gain. Section 16(a) requires Section 16 Insiders to publicly disclose any changes in their beneficial ownership of the Company’s equity securities (see the Filing Requirements section below). Section 16(b) requires Section 16 Insiders to disgorge to the Company any “profit” resulting from “short-swing” trades, as discussed more fully below. Section 16(c) effectively prohibits Section 16 Insiders from engaging in short sales (see the Prohibition of Short Sales section, below).

Under Section 16(b), any profit realized by a Section 16 Insider on a “short-swing” transaction (i.e., a purchase and sale, or sale and purchase, of the Company’s equity securities within a period of less than six months) must be disgorged to the Company upon demand by the Company or a stockholder acting on its behalf. By law, the Company cannot waive or release any claim it may have under Section 16(b) or enter into an enforceable agreement to provide indemnification for amounts recovered under the section. Liability under Section 16(b) is imposed in a mechanical fashion without regard to whether the Section 16 Insider intended to violate the section. Good faith, therefore, is not a defense. All that is necessary for a successful claim is to show that the Section 16 Insider realized “profits” on a short-swing transaction; however, profit, for this purpose, is calculated as the difference between the sale price and the purchase price in the matching transactions, and may be unrelated to the actual gain on the shares sold. When computing recoverable profits on multiple purchases and sales within a six month period, the courts maximize the recovery by matching the lowest purchase price with the highest sale price, the next lowest purchase price with the next highest sale price, and so on. The use of this method makes it possible for a Section 16 Insider to sustain a net loss on a series of transactions while having recoverable profits.
The terms “purchase” and “sale” are construed under Section 16(b) to cover a broad range of transactions, including acquisitions and dispositions in tender offers and certain corporate reorganizations. Moreover, purchases and sales by a Section 16 Insider may be matched with transactions by any person (such as certain family members) whose securities are deemed to be beneficially owned by the Section 16 Insider.
The Section 16 rules are complicated and present ample opportunity for inadvertent error. To avoid unnecessary costs and potential embarrassment for Section 16 Insiders and the Company, Section 16 Insiders are strongly urged to consult with the Company’s Office of the General Counsel prior to engaging in any transaction or other transfer of Company equity securities regarding the potential applicability of Section 16(b).

Under Section 16(c), Section 16 Insiders are prohibited from effecting “short sales” of the Company’s equity securities. A “short sale” is one involving securities which the seller does not own at the time of sale, or, if owned, are not delivered within 20 days after the sale or deposited in the mail or other usual channels of transportation within five days after the sale. Wholly apart from Section 16(c), the Company prohibits directors, officers, and employees from selling the Company’s stock short. This type of activity is inherently speculative in nature and is contrary to the best interests of the Company and its shareholders.

Filing Requirements
1.Forms 3, 4, and 5. Under Section 16(a) of the 1934 Act, Section 16 Insiders must file with the SEC and any stock exchange on which the Company’s equity securities are listed (i.e., The New York Stock Exchange) public reports disclosing their holdings of and transactions involving the Company’s equity securities. Copies of these reports must also be submitted to the Company. An initial report on Form 3 must be filed by every Section 16 Insider within 10 days after election or appointment disclosing their holdings of and transactions involving the Company’s equity securities. Copies of these reports must also be submitted to the Company. An initial report on Form 3 must be filed by every Section 16 Insider within 10 days after election or appointment disclosing all equity securities of the Company beneficially owned by the reporting person on the date such person became a Section 16 Insider. Even if no securities were owned on that date, the Section 16 Insider must file a report. Any subsequent change in the nature or amount of beneficial ownership by the Section 16 Insider, including dispositions via bona fide gifts, must be reported on Form 4 and filed within two business days after the transaction date. Certain exempt transactions may be reported on Form 5 within 45 days after the end of the fiscal year. The fact that a Section 16 Insider’s transactions during the month resulted in no net change, or the fact that no securities were owned after the transactions were completed, does not provide a basis for failing to report.

All changes in the amount or the form (i.e., direct or indirect) of beneficial ownership (not just purchases and sales) must be reported. Thus, such transactions as gifts and stock dividends ordinarily are reportable. Moreover, an officer or director who has ceased to be an officer or director must report any transactions after termination which occurred within six months of a transaction that occurred while the person was a Section 16 Insider.
The reports under Section 16(a) are intended to cover all securities beneficially owned either directly by the Section 16 Insider or indirectly through others. A Section 16 Insider is considered the direct owner of all Company equity securities held in his or her own name or held jointly with others. A Section 16 Insider is considered the indirect owner of any securities from which he obtains benefits substantially equivalent to those of ownership. Thus, equity securities of the Company beneficially owned through partnerships, corporations, trusts, estates, and by family members generally are subject to reporting. Absent countervailing facts, a Section 16 Insider is presumed to be the beneficial owner of securities held by his or her spouse and other family members sharing the same home. But a Section 16 Insider is free to disclaim beneficial ownership of these or any other securities being reported if the Section 16 Insider believes there is a reasonable basis for doing so.
It is important that reports under Section 16(a) be prepared properly and filed on a timely basis. The reports must be received at the SEC by the filing deadline. There is no provision for an extension of the filing deadlines,

and the SEC can take enforcement action against Section 16 Insiders who do not comply fully with the filing requirements. In addition, the Company is required to disclose in its annual proxy statement the names of Section 16 Insiders who failed to file Section 16(a) reports properly during the fiscal year, along with the particulars of such instances of noncompliance. Accordingly, the Company strongly urges all Section 16 Insiders to notify the Company’s Office of the General Counsel prior to any transactions or changes in their or their family members’ beneficial ownership involving Company stock and to avail themselves of the assistance available from the General Counsel’s office in satisfying the reporting requirements.

2.Schedule 13D and 13G. Section 13(d) of the 1934 Act requires the filing of a statement on Schedule 13D (or on Schedule 13G, in certain limited circumstances) by any person or group that acquires beneficial ownership of more than five percent of a class of equity securities registered under the 1934 Act. The threshold for reporting is met if the stock owned, when coupled with the amount of stock subject to options exercisable within 60 days, exceeds the five percent limit. A report on Schedule 13D is required to be filed with the SEC and submitted to the Company within ten days after the reporting threshold is reached. If a material change occurs in the facts set forth in the Schedule 13D, such as an increase or decrease of one percent or more in the percentage of stock beneficially owned, an amendment disclosing the change must be filed promptly. A decrease in beneficial ownership to less than five percent is per se material and must be reported.
A person is deemed the beneficial owner of securities for purposes of Section 13(d) if such person has or shares voting power (i.e., the power to vote or direct the voting of the securities) or dispositive power (i.e., the power to sell or direct the sale of the securities). As is true under Section 16(a) of the 1934 Act, a person filing a Schedule 13D may disclaim beneficial ownership of any securities attributed to him or her if he or she believes there is a reasonable basis for doing so.

3.Form 144. As described above under the discussion of Rule 144, an affiliate relying on Rule 144 must file a notice of proposed sale with the SEC at the time the order to sell is placed with the broker unless the amount to be sold in any three-month period neither exceeds 5,000 shares nor involves sale proceeds greater than $50,000.

GENERAL
The Company reserves the right to amend or terminate this policy as the Company deems necessary or warranted, in accordance with applicable laws.
ROLES AND RESPONSIBILITIES
Any questions related to the interpretation of this policy and/or a subject matter included in this policy shall be directed to the Office of the General Counsel.

GLOBAL CORPORATE POLICY
Doc #: GLBL-POL-00093
Rev #: 1
Effective Date: 2023/10/23
Policy Sponsor: Corporate Legal
Title: Financial Statement Compensation Recoupment Policy


PURPOSE
This Policy provides for the recoupment of certain executive compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting requirements under U.S. federal securities laws in accordance with the terms and conditions set forth herein. This Policy is intended to comply with the requirements of Section 10D of the Exchange Act and the Listing Rule.
SCOPE
This policy applies to all Executive Officers of Charles River, as defined below.
DEFINITIONS
“Adjusted Compensation” means the amount of Covered Compensation that would have otherwise been received by a Covered Executive if calculated based on the Financial Restatement.
“Awarded Compensation “ means the amount of any Covered Compensation received by a Covered Executive.
“Board” means the Board of Directors of Charles River Laboratories International, Inc.
“Code” means U.S. Internal Revenue Code of 1986, as amended.
Committee” means the Compensation Committee of the Board or any successor committee thereof.
“Company” means Charles River Laboratories International, Inc.
Covered Compensation” means any Incentive-based Compensation “received” by a Covered Executive during the applicable Recoupment Period; provided that:
(a)such Incentive-based Compensation was received by such Covered Executive (A) on or after the Effective Date, (B) after he or she commenced service as an Executive Officer and (C) while the Company had a class of securities publicly listed on a United States national securities exchange; and

Page 1 of 7





(b)such Covered Executive served as an Executive Officer at any time during the performance period applicable to such Incentive-based Compensation.

For purposes of this Policy, Incentive-based Compensation is “received” by a Covered Executive during the fiscal period in which the Financial Reporting Measure applicable to such Incentive-based Compensation (or portion thereof) is attained, even if the payment or grant of such Incentive-based Compensation is made thereafter.

Covered Executive” means any current or former Executive Officer

Effective Date” means the date on which the Listing Rule becomes effective.

“Erroneously Awarded Compensation” means the excess of the Awarded Compensation over the Adjusted Compensation.

Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended.

Executive Officer” means, with respect to the Company, any person who is an "officer" within the meaning of Rule 16a-1(f) promulgated under the Securities Exchange Act of 1934, as amended, or any successor rule.

Financial Reporting Measure” means any (i) measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, (ii) stock price measure or (iii) total shareholder return measure (and any measures that are derived wholly or in part from any measure referenced in clause (i), (ii) or (iii) above). For the avoidance of doubt, any such measure does not need to be presented within the Company’s financial statements or included in a filing with the U.S. Securities and Exchange Commission to constitute a Financial Reporting Measure.

Financial Restatement” means a restatement of the Company’s financial statements due to the Company’s material noncompliance with any financial reporting requirement under U.S. federal securities laws that is required in order to correct:

(a)an error in previously issued financial statements that is material to the previously issued financial statements; or
(b)     an error that would result in a material misstatement if the error were (A) corrected in the current     period or (B) left uncorrected in the current period.

For purposes of this Policy, a Financial Restatement shall not be deemed to occur in the event of a revision of the Company’s financial statements due to an out-of-period adjustment (i.e., when the error is immaterial to the previously issued financial statements and the correction of the error is also immaterial to the current period) or a retrospective (1) application of a change in accounting principles; (2) revision to reportable segment information due to a change in the structure of the Company’s internal organization; (3) reclassification due to a discontinued operation; (4) application of a change in reporting entity, such as from a reorganization of entities under common control; or (5) revision for stock splits, reverse stock splits, stock dividends or other changes in capital structure.

For purposes of this Policy, “Incentive-based Compensation” shall also be deemed to include any amounts which were determined based on (or were
Page 2 of 7



otherwise calculated by reference to) Incentive-based Compensation (including, without limitation, any amounts under any long-term disability, life insurance or supplemental retirement or severance plan or agreement or any notional account that is based on Incentive-based Compensation, as well as any earnings accrued thereon).
“JAMS” means Judicial Arbitration and Mediation Services, Inc.

Listing Rule” means Section 303A.14 of the NYSE Listed Company Manual or any successor provision thereof.

NYSE” means the New York Stock Exchange, or any successor thereof.

Recoupment Period” means the three fiscal years completed immediately preceding the date of any applicable Recoupment Trigger Date. Notwithstanding the foregoing, the Recoupment Period additionally includes any transition period (that results from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years, provided that a transition period between the last day of the Company’s previous fiscal year end and the first day of its new fiscal year that comprises a period of nine (9) to twelve (12) months would be deemed a completed fiscal year.

Recoupment Trigger Date” means the earlier of (i) the date that the Board (or a committee thereof or the officer(s) of the Company authorized to take such action if Board action is not required) concludes, or reasonably should have concluded, that the Company is required to prepare a Financial Restatement, and (ii) the date on which a court, regulator or other legally authorized body directs the Company to prepare a Financial Restatement.

POLICY

1.Recoupment of Erroneously Awarded Compensation
(a)In the event of a Financial Restatement, if the Awarded Compensation exceeds the amount of Adjusted Compensation, the Company shall reasonably promptly recover from such Covered Executive an amount equal to the Erroneously Awarded Compensation, each calculated on a pre-tax basis.

(b) If (i) the Financial Reporting Measure applicable to the relevant Covered Compensation is stock price or total shareholder return (or any measure derived wholly or in part from either of such measures) and (ii) the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the Financial Restatement, then the amount of Erroneously Awarded Compensation shall be determined (on a pre-tax basis) based on the Company’s reasonable estimate of the effect of the Financial Restatement on the Company’s stock price or total shareholder return (or the derivative measure thereof) upon which such Covered Compensation was received.

(c)For the avoidance of doubt, the Company’s obligation to recover Erroneously Awarded Compensation is not dependent on (i) if or when the restated financial statements are filed or (ii) any fault of any Covered Executive for the accounting errors or other actions leading to a Financial Restatement.

Page 3 of 7



(d)Notwithstanding anything to the contrary in Sections 1 (a) through (c) hereof, the Company shall not be required to recover any Erroneously Awarded Compensation if both (x) the conditions set forth in either of the following clauses (i) or (ii) are satisfied and (y) the Committee (or a majority of the independent directors serving on the Board) has determined that recovery of the Erroneously Awarded Compensation would be impracticable:

(i)the direct expense paid to a third party to assist in enforcing the recovery of the Erroneously Awarded Compensation under this Policy would exceed the amount of such Erroneously Awarded Compensation to be recovered; provided that, before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation pursuant to this Section 1(d), the Company shall have first made a reasonable attempt to recover such Erroneously Awarded Compensation, document such reasonable attempt(s) to make such recovery and provide that documentation to the NYSE; or

(ii)recovery of the Erroneously Awarded Compensation would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Sections 401(a)(13) or 411(a) of the Code.

(e)The Company shall not indemnify any Covered Executive, directly or indirectly, for any losses that such Covered Executive may incur in connection with the recovery of Erroneously Awarded Compensation pursuant to this Policy, including through the payment of insurance premiums or gross-up payments.

(f)The Committee shall determine, in its sole discretion, the manner and timing in which any Erroneously Awarded Compensation shall be recovered from a Covered Executive in accordance with applicable law, including, without limitation, by (i) requiring reimbursement of Covered Compensation previously paid in cash; (ii) seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer or other disposition of any equity or equity-based awards; (iii) offsetting the Erroneously Awarded Compensation amount from any compensation otherwise owed by the Company or any of its affiliates to the Covered Executive; (iv) cancelling outstanding vested or unvested equity or equity-based awards; and/or (v) taking any other remedial and recovery action permitted by applicable law. For the avoidance of doubt, except as set forth in Section 1(d), in no event may the Company accept an amount that is less than the amount of Erroneously Awarded Compensation; provided that, to the extent necessary to avoid any adverse tax consequences to the Covered Executive pursuant to Section 409A of the Code, any offsets against amounts under any nonqualified deferred compensation plans (as defined under Section 409A of the Code) shall be made in compliance with Section 409A of the Code.

2.Administration
This Policy shall be administered by the Committee. All decisions of the Committee shall be final, conclusive and binding upon the Company and the Covered Executives, their beneficiaries, heirs, executors, administrators and any other legal representative. The Committee shall have full power and authority to (i) administer and interpret this Policy; (ii) correct any defect, supply any omission and reconcile any inconsistency in this Policy; and (iii) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of this Policy and to comply with applicable law (including Section 10D of the Exchange Act) and applicable stock market or exchange rules and regulations. . Notwithstanding anything to the contrary contained herein, to the extent permitted by Section 10D of the Exchange Act and the Listing Rule, the Board may, in its sole discretion, at any time and from time to time, administer this Policy in the same manner as the Committee.

Page 4 of 7



3.Amendment/Termination
Subject to Section 10D of the Exchange Act and the Listing Rule, this Policy may be amended or terminated by the Committee at any time. To the extent that any applicable law, or stock market or exchange rules or regulations require recovery of Erroneously Awarded Compensation in circumstances in addition to those specified herein, nothing in this Policy shall be deemed to limit or restrict the right or obligation of the Company to recover Erroneously Awarded Compensation to the fullest extent required by such applicable law, stock market or exchange rules and regulations. Unless otherwise required by applicable law, this Policy shall no longer be effective from and after the date that the Company no longer has a class of securities publicly listed on a United States national securities exchange.

4.Interpretation
Notwithstanding anything to the contrary herein, this Policy is intended to comply with the requirements of Section 10D of the Exchange Act and the Listing Rule (and any applicable regulations, administrative interpretations or stock market or exchange rules and regulations adopted in connection therewith). The provisions of this Policy shall be interpreted in a manner that satisfies such requirements and this Policy shall be operated accordingly. If any provision of this Policy would otherwise frustrate or conflict with this intent, the provision shall be interpreted and deemed amended so as to avoid such conflict.
5.Other Compensation Clawback/Recoupment Rights.
Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies, rights or requirements with respect to the clawback or recoupment of any compensation that may be available to the Company pursuant to the terms of any other recoupment or clawback policy of the Company (or any of its affiliates) that may be in effect from time to time, any provisions in any employment agreement, offer letter, equity plan, equity award agreement or similar plan or agreement, and any other legal remedies available to the Company, as well as applicable law, stock market or exchange rules, listing standards or regulations; provided, however, that any amounts recouped or clawed back under any other policy that would be recoupable under this Policy shall count toward any required clawback or recoupment under this Policy and vice versa.

6.Exempt Compensation
Notwithstanding anything to the contrary herein, the Company has no obligation under this Policy to seek recoupment of amounts paid to a Covered Executive which are granted, vested or earned based solely upon the occurrence or non-occurrence of nonfinancial events. Such exempt compensation includes, without limitation, base salary, time-vesting awards, compensation awarded on the basis of the achievement of metrics that are not Financial Reporting Measures or compensation awarded solely at the discretion of the Committee or the Board, provided that such amounts are in no way contingent on, and were not in any way granted on the basis of, the achievement of any Financial Reporting Measure performance goal.
7.Miscellaneous
Page 5 of 7



(a)Any applicable award agreement or other document setting forth the terms and conditions of any compensation covered by this Policy shall be deemed to include the restrictions imposed herein and incorporate this Policy by reference and, in the event of any inconsistency, the terms of this Policy will govern.
