PART I

ITEM 1 – BUSINESS

Corporate History

Inotiv, Inc. and its subsidiaries (“we,” “our,” “us,” the “Company,” or “Inotiv”) began operating in 1975 as Bioanalytical Systems, Inc. Bioanalytical Systems, Inc. was incorporated in 1974 and completed an initial public offering in 2000. On March 18, 2021, the Company changed its corporate name from Bioanalytical Systems, Inc. to Inotiv, Inc. Our stock is traded on The Nasdaq Stock Market LLC under the symbol “NOTV.” We are headquartered in West Lafayette, Indiana. Our headquarters mailing address is 2701 Kent Avenue, West Lafayette, Indiana 47906, and the telephone number at that location is (765) 463-4527. Our Internet site is www.inotivco.com. The information contained on our website is not a part of this Report and is not incorporated by reference herein.

Overview

Inotiv is a leading contract research organization (“CRO”) dedicated to providing nonclinical and analytical drug discovery and development services primarily to the pharmaceutical and medical device industries and selling a range of research-quality animals and diets to the same industries as well as academia and government clients. Our products and services enable the discovery and development of new drugs and medical devices and facilitate better understanding of disease biology, all while focusing on increasing efficiency, improving data, and reducing the cost of discovering and taking new drugs and medical devices to market. Inotiv is committed to supporting discovery and development objectives as well as helping researchers realize the full potential of their critical research and development projects, all while working together to build a healthier and safer world. We are dedicated to practicing high standards of laboratory animal care and welfare.

As a result of our strategic acquisition of Envigo RMS Holding Corp. (“Envigo”) in November 2021, which added a complementary research model platform, our full spectrum solutions now span two segments: Discovery and Safety Assessment (“DSA”) and Research Models and Services (“RMS”).

Table of Contents

Through our DSA segment, we support the discovery, nonclinical development and clinical development needs of researchers and clinicians for primarily small molecule drug candidates, as well as biotherapeutics and biomedical devices. Our scientists have skills in analytical instrumentation development, chemistry, computer software development, histology, pathology, physiology, surgery, analytical chemistry, drug metabolism, pharmacokinetics, and toxicology to make the services and products we provide increasingly valuable to our current and potential clients. Our principal clients are companies whose scientists are engaged in analytical chemistry, drug safety evaluation, clinical trials, drug metabolism studies, pharmacokinetics and basic research, from small start-up biotechnology companies to some of the largest global pharmaceutical companies.

Through our RMS segment, we offer access to a wide range of small and large research models for basic research and drug discovery and development, as well as specialized models for specific diseases and therapeutic areas. We combine deep animal husbandry expertise with extensive knowledge and expertise in managing breeding genetics and high health status facilities, geared toward the delivery of high quality laboratory animals for research. In conjunction with our CRO business, we have the ability to run selected nonclinical studies directly on-site at closely located research model facilities and provide access to innovative genetically engineered models and services solutions. Our principal clients include biopharmaceutical companies, CROs, and academic and government organizations.

During the twelve months ended September 30, 2023, we focused our efforts on our site optimization strategy, which includes 11 facilities in addition to the exit of our Israel businesses, the completion of the build-out of a newly leased 48,000 square foot facility in Rockville, Maryland (“Rockville”) and addressing the shortage of nonhuman primate research models. As of September 30, 2023, we had completed the sale of the Israel businesses and the closure and consolidation of seven U.S. facilities and the facilities in France, Italy and Spain. One of our U.K. facilities is expected to close and consolidate with our other U.K. facility by the end of March. The facility build-out at Rockville was substantially complete in March 2023, and we are continuing to validate the equipment and assays required to support growth in both the genetic toxicology and biotherapeutics businesses.

Discovery and Safety Assessment

The DSA segment is comprised of two principal areas of services: Discovery Services (“Discovery”) and Safety Assessment.

Discovery Services

•Analytical Method Development and Validation: Analytical methods are developed and validated in a manner designed to ensure that data generated are accurate, precise, reproducible and reliable and are used consistently throughout the drug development process and in later product support. Both early-stage, fit-for-purpose discovery methods and fully Good Laboratory Practice (“GLP”)-validated methods are generated to provide appropriate and timely responses to the client’s situation.

•In Vivo Pharmacology: We provide preclinical in vivo efficacy services. In vivo pharmacology is strengthened by the combination of our genetically-modified rodent production capability which provides animals with specific genetic modifications necessary for evaluation of new molecular targets.

•Exploratory Pharmacokinetics and Toxicology: We evaluate the initial pharmacokinetics of drug candidates to determine oral bioavailability, dose proportionality of exposure, gender differences, and time-dependent changes in exposure in our laboratories. In addition we provide initial safety evaluation of drug candidates through the conduct of single and repeated dose exploratory toxicology studies designed to identify tolerability and target organ toxicity and to provide guidance for dosing of more extensive pivotal studies which are intended to support human clinical trials.

•Archiving Services: We provide climate-controlled archiving services for our clients’ data and samples at all of our facilities.

•Analytical Products: Analytical products consist of our liquid chromatographic and electrochemical instruments with associated accessories. The critical component of these products is the Epsilon® electrochemical platform. This platform incorporates all the hardware capabilities needed for most electrochemical experiments but can be modified through software development. The market for our analytical products is comprised principally of academic institutions and industrial research companies.

Table of Contents

•In Vivo Sampling Products: In vivo sampling products consist of the Culex® family of automated in vivo sampling and dosing instruments. These instruments are used by pharmaceutical researchers to dose animals and collect biological samples (blood, bile, urine, microdialysate, feces or any bio-fluid) from the animals. Since dosing and sample collections are automated, animals are not manually handled, reducing stress on the animals and producing more representative pharmacological data. Behavior and other physiological parameters can also be monitored simultaneously. Compared to manual methods, the Culex® products offer significant reduction in test model use and comparable reduction in labor. The line also includes in vivo sampling devices sold to drug developers and medical research centers to assist in the study of a number of medical conditions including stroke, depression, Alzheimer’s and Parkinson’s diseases, diabetes and osteoporosis.

Safety Assessment

•Non-clinical Toxicology and Pathology Services: We provide safety testing in studies ranging from acute safety evaluation of drugs and medical devices to chronic, multi-year oncogenicity studies, and safety evaluation focused on developmental and reproductive toxicology. We also provide services in toxicologic pathology and evaluation of tissues from animal efficacy models, surgical modeling and focused evaluation of biomedical devices as well as cardiovascular safety evaluation in radiotelemetry-implanted animals.

•Stability Testing: We test stability of nonclinical drug dosing formulations and collect bioanalysis samples designed to ensure the integrity of all solutions used in nonclinical and clinical studies and post-study analyses. Results from sample shipping and storage studies assist our clients in maintaining sample integrity throughout the process from collection to analysis.

•Drug Metabolism, Bioanalysis, and Pharmacokinetics Testing: We analyze samples from in vitro, preclinical and clinical studies to identify and measure drug and metabolite concentrations in complex biological matrices, including drug metabolism, bioanalysis and pharmacokinetics studies.

New Service Offerings

During the twelve months ended September 30, 2023 and 2022, we spent $6.9 million and $5.7 million, respectively, on startup costs for new service offerings that we are building internally such as: mechanistic pharmacology and toxicology, safety pharmacology; juvenile toxicology; SEND (Standard for the Exchange of Nonclinical Data) data reporting; clinical pathology; biotherapeutics; histopathology for devices; genetic toxicology; and cardiovascular safety pharmacology.

Research Models and Services

The RMS segment is comprised of (1) Research Models, (2) Diets and Bedding, and (3) Research Model Services.

Research Models: Our research models business is comprised of the commercial production and sale of laboratory animals and research models, principally purpose-bred rats and mice and large animal models (non-human primates (“NHP”) and rabbits) for use by researchers. We provide these models to numerous clients around the world, including many academic institutions, government agencies, biopharmaceutical companies, and CROs, and we have a global footprint with production facilities strategically located in three countries.

Our research models include standard stocks and strains, immunocompromised models (which are useful for oncology research), disease models (which are in demand as early-stage research tools) and genetically-engineered models ((“GEMS”), which are often created for specific research projects).

•Small Animal Research Models: Our rodent species have been and continue to be among the most-used research models in the world, largely as a result of our geographic footprint and commitment to quality and client service. Our small animal 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 research results. With our production capabilities, we strive to consistently deliver high-quality research models worldwide.

RMS rodent research models include:

•outbred, which are purposefully bred for heterogeneity;

8

Table of Contents

•inbred, which are bred to be genetically identical;

•spontaneous mutant, which contain a naturally occurring genetic mutation (such as immune deficiency);

•hybrid, which are the offspring of two different inbred parents; and

•GEMS.

Certain of our models are proprietary, disease-specific rodent models used to research treatments for diseases such as diabetes, obesity, cardiovascular and kidney disease.

•Large Research Models: Our large animal portfolio includes NHPs and rabbits. NHPs are generally imported into the U.S. and Europe from Asia and Africa, with limited breeding in the U.S. We operate two quarantine facilities in the U.S. to house and clear these imported animals before onward shipment to clients. NHPs are used by our clients primarily for the safety testing of new biological therapies. Rabbits are bred in both the U.K. and U.S. and utilized primarily for the reproductive safety testing of potential new therapies.

Diets and Bedding: Through its Teklad product line (“Teklad”), RMS produces and sells laboratory animal diets, bedding, and enrichment products. With primary manufacturing operations in the U.S. and a primarily company-owned and/or managed distribution network throughout the U.S., U.K. and Europe, we distribute Teklad products globally. We also maintain contract-manufacturing relationships with companies in the U.K. and Italy.

Teklad offers a full line of off-the-shelf formulations as well as custom diets to meet our clients’ specific research needs. A team of nutritionists, including several PhDs, work with our clients to determine the best diet for their research objectives. If a custom diet is required, our nutritionists define the appropriate formula and our custom diet manufacturing line produces the feed. Our manufacturing facilities are ISO 9001:2015 certified.

Teklad diets are manufactured from natural ingredients and use fixed formulas. In conjunction with strict quality standards for raw materials, this approach helps to ensure quality and consistency by minimizing variability of both nutrients and certain natural chemicals in the diet which might affect a research study. Teklad offers a variety of bedding and enrichment products to support model breeding, weaning, and holding.

Research Model Services: We also offer a variety of services designed to support our clients' use of research models in basic research and product development. These services include specialized surgical modifications such as cannulation, implants, and the creation of surgically derived disease state models. We also provide contract breeding, contract colony management, health monitoring, quarantine, cryopreservation, rederivation and revitalization services, as well as antibody development and production. Lastly, through the GEMS business, we offer the creation of new transgenic research models specific to individual clients’ needs.

The Company’s Role in the Drug Development Process

Inotiv provides research support, through provision of its products and services, for the identification and development of new chemical and biological entities from discovery through clinical development. Our DSA segment provides services related to efficacy and safety evaluations and our RMS segment offers animal research models for use in efficacy and safety evaluations.

1.The discovery phase of new product development includes the identification and validation of potential targets for therapeutic intervention, the latter of which may involve studying a disease’s molecular pathway by genetically altering one or more of the molecules in that pathway in cell lines or in murine models. Inotiv’s molecular biology group creates such murine models for our clients and, where appropriate, can then support clients in the use of those models to study the pharmacokinetic and potential efficacy profiles of new therapeutic entities.

In addition to generation of new models for studying potential pharmacokinetics and efficacy at the request of our clients, Inotiv also has a broad range of off-the-shelf standard, and disease-bearing models, that may be used for the same purposes. Our discovery services group uses these animals, and other model systems, to perform a range of early discovery tests to better characterize potential new therapeutic molecules for mode of action, potential efficacy, and predicted safety and metabolism profiles.

2.After a new drug candidate is identified and carried through this preliminary discovery screening, the development process for new drugs has three distinct phases: the nonclinical phase, the clinical phase and the post approval

Table of Contents

phase. The nonclinical phase includes safety testing to prepare an Investigational New Drug ("IND") application for submission to the U.S. Food and Drug Administration (“FDA”). The IND must be accepted by the FDA before the drug candidate can be initially tested in humans. Once a pharmacologically active molecule is fully analyzed to confirm its potential utility, the initial dosage form for clinical trials is created. An analytical chemistry method is developed to enable reliable quantification. Stability and purity of the formulation are also determined.

Clients work with our nonclinical services group to establish initial pharmacology, pharmacokinetics (“PK”), pharmacodynamics (“PD”) and safety characteristics of the drug candidate. The safety studies range from dose ranging studies, that involve acute safety evaluation of drug candidates and medical devices to chronic, multi-year oncogenicity and reproductive toxicity studies. Dose formulation analysis is provided by our pharmaceutical analysis group. Bioanalyses of blood sampled under these protocols by our bioanalytical services group provide pharmacokinetic and metabolism data that is used with the safety and toxicity information to determine the exposure required to demonstrate toxicity. A no observable adverse effect level is then established for the drug and sets the basis for future safety testing and clinical Phase I studies. Upon successful completion of nonclinical safety studies, an IND submission is made by the sponsor and must be approved by FDA prior to initiation of human clinical trials.

Our bioanalytical services group utilizes our depth of expertise in liquid chromatography with detection by mass spectrometry to support research, nonclinical and clinical programs. We also offer bioanalytical services that utilize electrochemistry, spectrophotometric (UV/Vis or fluorescence) and Corona Discharge detection as options. We have invested in robotics and mass spectrometry systems. Application of this technology allows us to rapidly develop and validate methods for new compounds and obtain information suitable for regulatory submission.

3.The clinical phase further explores the safety and efficacy of the drug candidate in humans. The sponsor conducts Phase I human clinical trials in a limited number of healthy individuals to determine safety and tolerability. Bioanalytical assays determine the availability and metabolism of the active ingredient following administration. Expertise in method development and validation is critical for new chemical entities and new biological entities.

Exhaustive safety, tolerability and dosing regimens are established in patients in Phase II trials. Phase III clinical trials verify efficacy and safety. After successful completion of Phase III trials, the sponsor of the new drug submits a New Drug Application ("NDA") or Biologics License Application ("BLA") to the FDA requesting that the product be approved for marketing. The bioanalytical sample count per study grows rapidly from Phase I through Phase III. Phase II and III studies may take several years to complete, and must be supported by well-proven and consistently applied analytical methods.

In parallel with the conduct of Phase II and Phase III clinical development, additional nonclinical animal studies (including sub-chronic and chronic toxicology studies, carcinogenicity studies and reproductive toxicology studies) are performed to allow the drug to proceed through clinical development and to support product registration.

Our services supporting clinical development include evaluation of bioequivalence and bioavailability to monitor the rate and extent to which a drug is available in the body and to demonstrate that the availability is consistent between formulations. We also offer in-vitro bioequivalence testing for poorly absorbed topical and oral drugs. We offer support and testing services in clinical sample development, release and stability.

4.The post-approval phase follows FDA approval of the NDA or BLA. This includes production and continued analytical and clinical monitoring of the drug. The post-approval phase also includes development and regulatory approval of product modifications and line extensions, including improved dosage forms. The drug manufacturer must comply with quality assurance and quality control requirements throughout production and must continue analytical and stability studies of the drug during commercial production to continue to validate production processes and confirm product shelf life. Samples from each manufactured batch must be tested prior to release of the batch for distribution to the public.

We also provide services during the post-approval phase, including bioequivalence studies of new formulations, line extensions, new disease indications and drug interaction studies. Our ability to offer Good Manufacturing Process ("GMP") electrochemical detection services has provided increased business opportunities for release testing.

Table of Contents

Increases in our services offerings have resulted in our ability to provide a broader range of services to our clients, often using combined services of several disciplines to address program needs. Our ability to solve problems by combining our knowledge base, services and products has been a factor in our selection by small startup biotechnology companies and major pharmaceutical companies to assist in several preclinical through post-approval phases.

Clients

We provide our services and products to organizations engaged in basic research, biomedical device and pharmaceutical research and development. During the twelve months ended September 30, 2023, we made sales to over 2,500 companies, ranging from emerging biopharmaceutical companies up to some of the largest pharmaceutical companies in the world. We discuss client concentration and geographic information related to our business in Note 5 – Segment and Geographic Information to our consolidated financial statements contained in Part II, Item 8.

Recurring business from existing clients is important to ongoing operations. Our clients’ needs for our services and products increase and decrease depending on the stage of their research activities, so we experience some client turnover. Our business development efforts focus on both expanding existing client relationships and acquiring new clients. Historically, our RMS segment has stable, long-term relationships with a majority of our clients due to their overarching preference for consistency in the products they use to conduct their studies. However, we are continuing our efforts to cross-sell and expand our client base. Our DSA segment, due to its broad menu of services and flexibility in study design, is well positioned to serve the emerging biopharmaceutical segment during the discovery and development phases. We discuss client concentration of revenue in Note 2 – Summary of Significant Accounting Policies to our consolidated financial statements contained in Part II, Item 8.

Contractual Arrangements

Our DSA contracts typically establish an estimated fee to be paid for a proposed set of services designed in consultation with the client. In most cases, some percentage of the contract fee is paid in advance. While we are performing a contract, clients often adjust the scope of services to be provided based on interim project results. Fees are adjusted accordingly. Generally, our fee-for-service contracts are terminable by the client upon written notice of 30 days or less for a variety of reasons, including the client’s decision to forego a particular study, the failure of product prototypes to satisfy safety requirements, and unexpected or undesired results of product testing. Cancellation or delay of ongoing contracts may result in fluctuations in our quarterly and annual results. We are generally able to recover, at a minimum, our invested costs when contracts are terminated.

Our RMS product contracts are typically short-term in nature and based upon purchase orders submitted by clients to satisfy specific requirements for their research. Pricing is based upon list prices, which are market-adjusted. In addition, prior to Inotiv’s acquisition of Envigo, Envigo entered into a five-year supplier agreement with a key strategic partner that includes minimum purchase commitments and preferred pricing (equal to best price extended to similar clients). The contract’s initial term ends during the third fiscal quarter 2024. However, it requires a two-year termination notice. Contract breeding and client-owned animal colony care contracts are generally billed as per diems over the contract period.

Sales and Marketing

We promote our services through concentrated business development efforts, scientist-to-scientist communications, centralized corporate marketing programs and social media to both pharmaceutical and medical device companies, as well as academic and government research institutions. We recognize that our growth depends upon our ability to continually improve client satisfaction in order to deepen existing and establish new client relationships.

In November of 2019, the Company rebranded its contract research services business as “Inotiv.” Adoption of the trade name Inotiv symbolized the expansion and supplementation of the Company’s legacy contract research service operations through significant business acquisitions as well as internal growth. Since the rebranding, the Company has marketed and otherwise managed its contract research services operations under the name Inotiv. On March 18, 2021, the Company changed its corporate name from Bioanalytical Systems, Inc. to Inotiv, Inc. Our research equipment manufacturing division continues to operate under the name BASi Research Products.

The Company acquired Envigo RMS Holding Corp in November of 2021. After its acquisition, the research models business of Envigo has continued to operate under the Envigo brand as “an Inotiv company” and comprises the majority of

the RMS segment of Inotiv. Since March of 2023, the Company has worked to consolidate all DSA and RMS products and services under the Inotiv trade mark, as evidenced by the launch of a unified website under the Inotiv domain.

Our commercial initiatives include integrated campaigns designed to help differentiate and promote our products and services. Through trade events, digital and print advertising, direct communication, newsletters, social media, virtual exhibit space and our website, we provide our perspective on current industry challenges and developments to create an ongoing dialogue with our clients and to promote our industry expertise, quality, technology and innovation. Historically, we have reinforced key messages and selling points through client visits, presentations, corporate material and at trade events and industry conferences. While trade events were almost entirely virtual from 2020 through 2022, nearly all have returned to in-person events.

We encourage and sponsor the participation of our scientific and technical personnel in a variety of professional endeavors, including in-person (seminar) and virtual (webinar) speaking engagements, the presentation of papers at national and international professional trade meetings and the publication of scientific articles in medical and pharmaceutical journals. Through these endeavors we seek to emphasize our reputation for both scientific depth and operational excellence.

As of September 30, 2023, in addition to our leadership team and scientists, we had 135 employees on our commercial team supporting sales, marketing, client experience, client service and program management for both our DSA and RMS clients. These resources are located in both North America and U.K./Europe to serve major research markets.

Competition

Our two operating segments compete with other businesses, which range in size and capabilities, both financial and operational. In addition to competing companies in both industries, we compete with internal research and development teams at our client companies. There is competition for clients on the basis of many factors, including scientific and technological expertise, quality, reputation, responsiveness, price, scope of product and related service offerings, and geographic presence. Further, specific to the RMS segment, we believe there are significant barriers to becoming a global provider including the construction of bio-secure barrier production facilities, flexible-film isolator production facilities and the population of these facilities with over 175 species and strains of animal models (including over 80 genetically engineered rodent models), which requires years of investment and strict operating procedures.

For DSA, we have many competitors, including two public companies in the U.S. and one public company in China.

For RMS, there are five main competitors, including one public company in the U.S., two privately-held companies in the U.S., one government-funded, not-for-profit entity in the U.S., and one privately-held company in Europe.

Industry Support and Animal Welfare

Inotiv is committed to delivering high-level health and genetic quality, operational performance and client service. High standards of animal welfare are vital to delivering on each of these objectives and are a principal focus of Inotiv.

Inotiv is an advocate for implementation of Replacement, Reduction and Refinement (“3Rs”). Members of Inotiv's scientific and technical care staff undertake continuing professional development in the field of laboratory animal science, with special focus on animal welfare and the 3Rs, and they are encouraged to publish and present within the scientific community.

Inotiv has formed internal Institutional Animal Care and Use Committees, comprising staff from many disciplines within the DSA and RMS segments, in addition to external representation, to implement applicable regulations and provide strict oversight of animal welfare matters. The majority of Inotiv’s animal production facilities are accredited by the Association for Assessment and Accreditation of Laboratory Animal Care International (“AAALAC”), a private, non-profit, international accrediting organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. Our facilities are also routinely inspected by government agencies tasked with enforcing animal welfare regulations.

Inotiv is firmly committed to the 3Rs and to reducing the number of animals used in research by emphasizing health and genetic integrity to decrease study data variability. Whenever possible, technological advances, such as new diagnostic tests for screening pathogens in laboratory rodents, micro-sampling and in vitro assays, are used.

Laboratory animals remain an essential component in the research and development that our clients conduct. They further our knowledge of living systems and help in the discovery and development of products that can save or enhance human and animal lives. The Company works with the scientific community to improve our understanding and promote best practice in the care and welfare of research animals. As providers of research models to the research community and scientists conducting experiments on behalf of our clients to help discover and develop new medicines, Inotiv is responsible to our clients and the public for the health and well-being of the animals in our care.

Human Capital Management

As of September 30, 2023, we had 1,955 full-time employees and 100 part-time employees. All employees enter into confidentiality agreements intended to protect our proprietary information. We believe that our relations with our employees are good. None of our employees are represented by a labor union. Our performance depends on our ability to attract and retain qualified professional, scientific and technical staff. The level of competition among employers for skilled personnel is high. We believe that our employee benefit plans enhance employee morale, professional commitment and work productivity and provide an incentive for employees to remain with the Company.

Our primary objectives and philosophy of our compensation programs are to (i) drive leadership behaviors that maximize long-term stockholder value creation and (ii) attract and retain talented colleagues with the skills necessary to successfully manage and grow our business.

Attracting, retaining, and developing talent is a core principle of our talent management and total rewards strategy. Compensation and benefit programs are an important part of our employment relationship, which also includes challenging and rewarding work, growth and career development opportunities and being part of a leading CRO with a diverse and talented workforce that helps clients develop life-changing therapies. We strive to have the following features as part of our compensation and benefits:

•a consistent framework that is affordable to the business;

•a pay for performance focus – individuals are rewarded for performance and overall contributions to business success;

•compensation is fair and equitable, irrespective of gender, race, or similar personal characteristics; and

•a total rewards package that will be competitive with leading companies.

Compensation is used to attract, retain, and motivate employees and to reward the achievement of business results through the delivery of competitive pay and discretionary incentive programs. Benefits provide employees with income security and protection from catastrophic loss. We will continue to evaluate and develop affordable, competitive benefit programs that meet these objectives. No one element is more important than any other, and business judgement is used to balance them to ensure our compensation and benefits strategy is effective in supporting our overall business strategy.

Our Guiding Principles consist of:

•Pay Equity – employee compensation should be fair and equitable.

•Performance Orientation – compensation programs should support and reinforce a pay-for-performance culture.

•Competitive Positioning – critical to attracting, motivating, and retaining a high-performance team.

•Affordability – compensation and benefits must be affordable to us over the medium to long-term.

•Consistency and Stability – compensation and benefit programs should have a high degree of consistency and should not significantly fluctuate year-over-year.

•Delivery Efficiency – compensation, benefits, and other related programs should be consistent, equitable and easy to administer.

•Deliver Effectiveness – clearly defined metrics should be developed for compensation, benefits, and other related programs that are aligned with corporate business performance metrics.

Attracting, retaining, and developing world class talent that is empowered to work together to compete and win is a fundamental aspect of our corporate strategy. A foundational principle of our talent management strategy is an unwavering

commitment to equal opportunity in all aspects of employment, including the way we compensate and reward our employees.

Regulatory Matters

We are subject to various federal, state, and local laws and regulations and inspections designed to promote compliance therewith. We strive to conduct our business in compliance with applicable laws and regulations. Violations of these laws and regulations may result in sanctions, including substantial fines, warning letters that require corrective action (including potential facilities improvement requirements), revocation of approvals, exclusion from future participation in government healthcare programs and grants, criminal prosecution and even the denial or debarment of the right to conduct business. We hold a range of permits and licenses, related to our activities.

We are subject to extensive regulatory requirements designed to ensure the quality and integrity of our data and products and to government inspections and audits related thereto. These regulations include those promulgated under the Federal Food, Drug and Cosmetic Act, as amended from time to time, and include GLP, GMP, Bioequivalence regulations (“BE”) and Good Clinical Practices ("GCP"). These requirements demand rigorous attention to research; development; safety; manufacturing quality control; employee training; detailed documentation; equipment and computer validation; promotion and advertising; careful tracking of changes and routine auditing of compliance. Noncompliance with these standards could result in disqualification of project data collected by the Company, which would substantially impact our ability to meet our obligations to clients, and, in severe cases, discontinuance of selected operations. The products and services we offer to international clients are also subject to foreign regulatory requirements, which vary from country to country. Since our formation, we have been inspected, on a routine basis, by the FDA at each of our locations.

We are subject to federal, state and foreign healthcare and other regulations, including anti-bribery and anti-corruption laws (such as the U.S. Foreign Corrupt Practices Act of 1977), and could face substantial penalties if we fail to comply with such regulations and laws. In particular, the relationships that we, and third parties that market and/or sell our products, have with purchasers of our products, are subject to scrutiny under various state and federal laws, including those referred to collectively as healthcare fraud and abuse laws.

Our facilities and operations are subject to various federal, state, and local laws and regulations relating to protection of human health and the environment, including those governing the discharge of pollutants into the environment and the storage, handling, use, treatment, disposal, and recycling of hazardous substances and wastes, as well as relating to the humane treatment of animals in our custody, as further described below. Such laws include, without limitation, the Clean Air Act, the Clean Water Act, the Toxic Substances Control Act, the Animal Welfare Act and the Resource Conservation and Recovery Act. As environmental laws and regulations continue to evolve, it is likely we will be subject to increasingly stringent environmental standards in the future, particularly under air and water quality laws and standards related to climate change issues. Environmental laws are complex, change frequently and have tended to become increasingly stringent over time.

Analytical Services

Laboratories that provide information included in INDs, NDAs and BLAs must conform to regulatory requirements that are designed to ensure the quality and integrity of the testing process. Most of our contract research services are subject to government standards for laboratory practices that are embodied in regulations for GLP, GMP, BE and GCP. The FDA, Environmental Protection Agency and other regulatory authorities require that test results submitted to such authorities be based on studies conducted in accordance with the regulations listed above. These requirements include but are not restricted to the following areas:

•Resources – organization, personnel, facilities and equipment;

•Rules – protocols and written procedures;

•Characterization – test items and test systems;

•Documentation – raw data, final report and archives; and

•Quality assurance unit – formalized internal audit function.

We must also maintain reports for each study for specified periods for auditing by the study sponsor and by the FDA or similar regulatory authorities in other parts of the world. Regulatory monitoring authorities such as the FDA, have

Table of Contents

indicated an increased emphasis on the management of electronic records generated by computerized systems to ensure data integrity. Noncompliance with these regulations can result in the disqualification of data collected during the preclinical trial, which would substantially impact our ability to meet our obligations to clients, and, in severe cases, discontinuance of selected operations.

Nonclinical Services

Our animal research facilities are subject to a variety of federal and state laws and regulations, including The Animal Welfare Act (“AWA”) and the rules and regulations enforced by the United States Department of Agriculture ("USDA") and the National Institutes of Health ("NIH"). These regulations establish the standards for the humane treatment, care and handling of animals by breeders, dealers and research facilities. Our animal research facilities maintain detailed standard operating procedures and other documentation designed to comply with applicable regulations for the humane treatment of the animals in our custody. If the USDA determines that our equipment, facilities, laboratories or processes do not comply with applicable AWA standards, it may issue an inspection report documenting the deficiencies and setting deadlines for any required corrective actions. For continued noncompliance, the USDA may impose fines, suspend and/or revoke animal research licenses or confiscate research animals. In addition to being licensed by the USDA as a research facility where applicable, we have registered assurances with the NIH.

Research Models and Services

As the RMS segment operates in a number of distinct environments and in a variety of locations worldwide, the RMS segment is subject to numerous, and sometimes overlapping, regulatory environments.

The AWA governs the care and use of certain species of animals used for research in the U.S. other than certain laboratory rats, mice and birds. For regulated species, the AWA and the associated animal care regulations require producers and users of regulated species to provide veterinary care and to utilize specific husbandry practices such as cage size, shipping conditions, sanitation and environmental enrichment to assure 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 produced by the Institute for Laboratory Animal Research.

The RMS segment is subject to licensing and registration requirement standards set by the USDA and similar agencies in other countries for the care and use of regulated species. Our operations in Europe are subject to the standards as stipulated by Directive 2010/63/EU on the Protection of Animals Used for Scientific Purposes. Stipulations within that Directive were transposed into national legislations within Europe in 2013. We are regularly consulted and inspected by the relevant national authorities in each nation in which we operate.

The RMS segment's import and export of animals and its operations in foreign countries are subject to 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 breeders, dealers and research facilities.

In addition, the specific activities of some of RMS lines of business require RMS entities to hold specialized licenses for the conduct, manufacture, and distribution of particular products and services.

All of RMS’s sites are subject to licensing and regulation under international treaties and conventions, including national, regional and local laws relating to:

•the surface and air transportation of laboratory specimens;

•the handling, use, storage and disposal of chemicals (including anesthetics, narcotics and psychotropic drugs), biological reagents, laboratory specimens, hazardous waste and radioactive materials;

•the safety and health of employees and visitors to our facilities; and

•protection of the environment and general public.

To meet these compliance obligations, Inotiv has established quality assurance procedures and functions. The quality assurance function operates independently from those individuals that manage RMS production.

Controlled, Hazardous, and Environmentally Threatening Substances

Some of our development and testing activities are subject to the Controlled Substances Act administered by the Drug Enforcement Agency ("DEA"), which strictly regulates all narcotic and habit-forming substances. We maintain restricted-access facilities and heightened control procedures for projects involving such substances due to the level of security and other controls required by the DEA.

Our laboratories are subject to licensing and regulation under federal, state and local laws relating to hazard communication and employee right-to-know regulations, the handling and disposal of medical specimens and hazardous waste, as well as the safety and health of laboratory employees. All of our laboratories are subject to applicable federal and state laws and regulations relating to the storage and disposal of laboratory specimens, including regulations of the Environmental Protection Agency, the Department of Transportation, the National Fire Protection Agency and the Resource Conservation and Recovery Act. We may incur liability for alleged environmental damages associated with the off-site transportation and disposal of hazardous substances. Generators of hazardous substances which are transported to disposal sites where environmental problems are alleged to exist are subject to claims under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (“CERCLA”), and state counterparts. CERCLA imposes strict, joint and several liabilities for investigatory and cleanup costs upon hazardous substance generators, site owners and operators, and other potentially responsible parties. We may be held liable for all costs arising out of any release of hazardous substances and for consequences arising out of human exposure to such substances, which costs may be material. In addition, changes in any environmental laws may increase costs of compliance and liabilities arising from any past or future releases of, or exposures to, hazardous substances and may materially adversely affect the business.

The regulations of the U.S. Department of Transportation, the PHS and the U.S. Postal Service apply to the surface and air transportation of laboratory specimens. Our laboratories must also comply with the International Air Transport Association regulations which govern international shipments of laboratory specimens. Furthermore, when materials are sent to a foreign country, the transportation of such materials becomes subject to the laws, rules and regulations of such foreign country.

Safety

In addition to comprehensive regulation of safety in the workplace generally, the Occupational Safety and Health Administration has established extensive requirements relating to workplace safety for health care employers, whose workers may be exposed to blood-borne pathogens such as HIV and the hepatitis B virus, chemicals and drugs, and respiratory hazards. These regulations, among other things, require work practice controls, protective clothing and equipment, training, medical follow-up, vaccinations and other measures designed to minimize exposure to chemicals, transmission of blood-borne and airborne pathogens, and other potential hazards. Relevant employees receive initial and periodic training focusing on compliance with applicable hazardous materials regulations and health and safety guidelines.

Trends Affecting the Drug Discovery and Development Industry

Our services and products are primarily marketed globally to pharmaceutical, medical research and biotechnology companies and institutions (academic and governmental) engaged in drug research and development. The research services industry is highly fragmented among many niche vendors as well as a small number of consolidating larger companies; the latter offer an ever-growing portfolio of start-to-finish pharmaceutical development services. Our services and products may have distinctly different clients (including separate divisions in a single large pharmaceutical company) and requirements. We believe that market trends in the pharmaceutical and biotech industries demonstrate an increasing emphasis towards outsourcing, as companies seek to maintain reduced internal resources in favor of variable cost models that offer high quality and higher accountability alternatives to meet their drug discovery, development and manufacturing needs. We believe that our clients are facing increased pressure to outsource facets of their research and development activities and that the following factors are the main contributors to client outsourcing.

Limited Research Model Availability

During the COVID-19 pandemic, researchers and CROs experienced significant limitations in their access to animal research models, specifically including a sharp reduction in the availability of NHPs originating from breeding farms in Southeast Asia. Prior to the pandemic, China was the leading exporter of NHPs employed in basic and applied research; however, early in 2020, China ceased exportation of cynomolgus monkeys, the species most commonly involved in pharmaceutical product development. This change in the world supply of a critical research model has resulted in a need to

16

Table of Contents

source increased numbers of NHPs from breeding farms principally located in Cambodia, Vietnam, and Mauritius Island, with a resultant marked increase in unit pricing. We do not know whether the embargo in China on exportation will loosen in the future.

On November 16, 2022, the Company became aware that the U.S. Attorney’s Office for the Southern District of Florida (“USAO-SDFL”) had criminally charged employees of the principal supplier of NHPs to the Company, along with two Cambodian government officials, with conspiring to illegally import NHPs into the United States from December 2017 through January 2022 and in connection with seven specific imports between July 2018 and December 2021. In addition, two of the Company's subsidiaries, Orient BioResource Center, Inc. ("OBRC") and Envigo Global Services, Inc., companies acquired by the Company on January 27, 2022 and November 5, 2021, respectively, have received grand jury subpoenas from USAO-SDFL requiring the production of documents and information related to their importation of NHPs into the U.S. The Company understands that one of the Cambodian government officials is currently scheduled to be tried by the USAO-SDFL in March 2024. The indictment further jeopardized the already constrained domestic supply of these critical animal models.

The limited NHP supply initially brought on by halting of Chinese exports and exacerbated by the events in Cambodia also resulted in an increase in the cost of these animals during fiscal year 2023, which could limit the ability of small innovator companies to fund the initial safety evaluation of new product candidates.

Accelerated Drug Development

Clients continue to demand faster, more efficient, more selective development of an increasing pool of drug candidates. Consequently, our clients require fast, high-quality service in order to make well-informed decisions to quickly exclude poor candidates and speed development of promising ones. The need for additional development capacity to exploit more opportunities, accelerate development, extend market exclusivity and increase profitability drives the demand for outsourced services.

Increase in Potential New Drug Candidates

The time and cost required to develop a new drug or device candidate have generally increased. Many small and virtual pharmaceutical and biotechnology companies do not have sufficient internal resources to pursue development of all of the new drug candidates on their own. Consequently, these companies are looking to the drug discovery and development services industry for cost-effective, innovative and rapid means of developing new drugs. Looking to the future, as we continue to explore how we can better support our customers, and their development of novel medicines going forward, we have embarked on a program to standardize the capture of data generated in discovery, safety, and clinical studies. The goal of this program is to structure our data in a way that, in the future, may allow an AI approach to integrate them to find correlations between discovery and safety data, and clinical outcomes that can innovate and accelerate our translational medicine offering.

Cost Pressures of Introducing New Drugs

Market forces, healthcare reform and other governmental initiatives place significant pressures on pharmaceutical and biotechnology companies to reduce drug prices. In addition, increased competition as a result of patent expiration, market acceptance of generic drugs, and governmental and privately managed care organization efforts to reduce healthcare costs have added to drug pricing pressures. The pharmaceutical industry is responding by consolidating, streamlining operations, decentralizing internal discovery and development processes, and minimizing fixed costs. In addition, increased pressures to differentiate products and justify drug pricing are resulting in an increased focus on healthcare economics, safety monitoring and commercialization services. Moreover, pharmaceutical and biotechnology companies are attempting to increase the speed and efficiency of internal new drug discovery and development processes.

Patent Expiration

As exclusivity ends with patent expiration, drug companies defend their proprietary positions against generic competition with various patent extension strategies. Both the drug company pursuing these extensions and the generic competitors provide additional opportunities for the Company.

Table of Contents

Alliances

Strategic alliances allow pharmaceutical companies to share research know-how and to develop and market new drugs faster in more diverse, global markets. We believe that such alliances will lead to a greater number of potential drugs in testing, many under study by small and virtual companies lacking broad internal resources to conduct such testing. These small and virtual companies can seek to add shareholder value by further developing new products through outsourcing, reducing risk for potential allies. Clients seek realistic business partnerships with their service provider in an effort to ensure that costs are controlled and scientific continuity is maintained as their development programs progress. We have long-standing business relationships with many pharmaceutical companies, continue to offer flexible services and aim to adapt to our clients’ requirements.

Mergers and Acquisitions

Consolidation in the pharmaceutical industry as well as its supporting contract research industry is commonplace. As pharmaceutical industry firms blend personnel, resources and business activities, we believe they will continue to streamline operations and minimize staffing, which will lead to more outsourcing and a dependence on small and virtual drug discovery efforts to feed their pipelines. Consolidation may result in a disruption in the progress of drug development programs as merging companies rationalize their respective drug development pipelines. In addition, we believe that recent consolidation within the contract research industry has created a unique opportunity for the emergence of mid-market CRO providers who can offer clients a high degree of “touch” not only in study execution, but in program design and regulatory agency interactions.

Biotechnology Industry and Virtual Drug Company Growth

The U.S. biotechnology industry has grown rapidly over the last two decades and has emerged as a key client segment for the drug discovery and development services industry. In recent years, this industry has generated significant numbers of new drug candidates that will require development and regulatory approval. Many biotechnology drug developers do not have sufficient in-house resources to conduct early stage drug development. Many new companies choose only to carry a product to a development stage sufficient to attract a partner who will manufacture and market the drug. Because of the time and cost involved, these companies typically rely heavily on CROs to conduct research for their drug candidates.

Specialized Technical Expertise

The increasing complexity of new drug candidates requires highly specialized, innovative, solution-driven research not available in all client labs. We believe that this need for specialized technical expertise will increasingly lead to outsourcing of research activity. We believe further that the reliance of the pharmaceutical industry on small innovative drug discovery companies, which are often overlooked by large CROs, creates an opportunity for strategic partnership with small, consulting-based and innovative CROs such as ours.

Data Management and Quality Expertise

Our clients and worldwide regulatory authorities require more data, greater access to that data, consistent and auditable management of that data, and greater security and control of that data. We have made investments in software throughout our contract services groups to optimize efficiency and promote compliance with regulations and market expectations.

Globalization of the Marketplace

Foreign firms rely on independent development companies like ours with experience in the U.S. to provide integrated services through all phases of product development and to assist in preparing complex regulatory submissions. Domestic drug firms are broadening product availability globally, which increases demand for local regulatory approval. We believe that we and other domestic service providers with global reach, established regulatory expertise, and a broad range of integrated development services and products will benefit from this trend.

Our Solution

We address the needs of the pharmaceutical and biotechnology industries, as well as academic, non-profit and government organizations, for drug discovery and development by providing integrated products and services to help our clients maximize the return on their research and development investments. We have focused on stabilizing critical supply chain

issues particularly related to research models. We believe our application of innovative technologies and products and our commitment to quality throughout the drug discovery and development process offer our clients a way to identify and develop successful drugs and devices more quickly and cost-effectively. We have obtained significant drug development expertise from almost 50 years of operation, and in recent years, we have added to our CRO service offerings through expansion of current facilities, acquisitions and startup initiatives to build new service offerings internally.

Product Liability and Insurance

We maintain product liability and professional errors and omissions liability insurance, providing coverage on a claims-made basis. Additionally, in certain circumstances, we seek to manage our liability risk through contractual provisions to be indemnified by the client or covered by the client’s liability insurance policies. Also, in certain types of engagements, we seek to limit our contractual liability to clients to the amount of fees received. Our client contractual arrangements are subject to negotiation, and the terms and scope of indemnification, liability limitation and insurance coverage vary by client and project.

Intellectual Property

We believe that our patents, trademarks, copyrights and other proprietary rights are important to our business. Accordingly, we actively seek protection for those rights both in the United States and abroad. Where we deem it to be an appropriate course of action, we will vigorously prosecute patent infringements.

Our issued patents are protected for durations ranging from October of 2031 to February of 2034. We also hold various U.S. registered copyrights. In addition to these formal intellectual property rights, we rely on trade secrets, unpatented know-how and continuing applications research which we seek to protect through means of reasonable business procedures, such as confidentiality agreements.

Raw Materials

There are no specialized raw materials that are particularly essential to our business. We have a variety of alternative suppliers for the components in our diets and bedding products.

ITEM 1A – RISK FACTORS

Our business is subject to many risks and uncertainties, which may affect our future financial performance or condition. If any of the events or circumstances described below occur, our business and financial performance or condition could be adversely affected, our actual results could differ materially from our expectations and the market value of our stock could decline. The risks and uncertainties discussed below are not the only ones we face. There may be additional risks and uncertainties not currently known to us or that we currently do not believe are material that may adversely affect our business and financial performance.

Risks Related to NHP Supply

Our business, results of operations, financial condition, including the carrying value of certain of our assets, and cash flows have and may continue to be adversely affected by our dependence on the importation of NHPs from suppliers located outside the U.S., particularly from communist countries in Southeast Asia, legal issues related to these suppliers, and any inability to diversify our suppliers located outside the U.S.

Our business, results of operations, financial condition, including the carrying value of certain of our assets, and cash flows have and may continue to be adversely affected by our dependence on NHP suppliers that are located outside the U.S. and difficulties in being able to diversify our suppliers located outside the U.S. China exited the NHP exportation market in 2020 during the COVID-19 pandemic, and has repeatedly stated that it strategically intends to dominate, amongst other things, worldwide biomedical research. As such, their demand for NHPs has shifted a previously exported supply to their domestic use. Legal matters affecting the Cambodian supply of NHPs , including those arising as a result of the USAO-SDFL criminally charging employees of our principal supplier of NHPs, along with two Cambodian government officials has further exacerbated an already constrained NHP supply for U.S. research. The Company understands that one of the Cambodian government officials is currently scheduled to be tried by the USAO-SDFL in March 2024. The allegations contained in that indictment also led us to refrain from selling or delivering any of the Cambodian NHPs we held in the U.S. until we could evaluate what additionally could be done to confirm that the NHPs in inventory from Cambodia could be reasonably determined to be purpose-bred. The decision to refrain from selling or delivering the Cambodian NHPs had a material adverse effect on our liquidity. In order to address the material adverse effect, we entered into an amendment to our credit facility.

While we are seeking to diversify our suppliers located outside the U.S., the number of NHP suppliers is limited, and we may not be successful in doing so. If we are unable to obtain NHPs in sufficient quantities of the required species or in a timely manner to meet the needs of our clients, if the price of NHPs that are available increases significantly, or if we are unable to ship the NHPs in our possession to our clients because of governmental restrictions or limitations, our business, particularly in our RMS segment, will be materially adversely affected.

In addition, overall supply constraints with respect to NHPs has led to an extremely dynamic pricing environment for NHPs, which has, and could continue to, make it difficult to predict results, lead to reduced volumes, and require us to adjust operations. Further, during fiscal 2023, the volume of NHPs we sold to third parties was significantly lower than in fiscal 2022.

Risks Related to Regulation and Legal Matters

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 employment and 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 Note 16 - Contingencies to our consolidated financial statements contained in Part II, Item 8, a putative securities class action and derivative securities lawsuits have been filed against the Company and certain officers and directors, alleging violations of the Exchange Act related to the Company’s disclosures concerning its acquisitions of Envigo and OBRC and their regulatory compliance.

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

22

Table of Contents

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.

We are subject to inspections, investigations and enforcement actions by regulatory authorities, which could lead to penalties, including substantial fines, warning letters, a temporary restraining order or injunction, civil and/or criminal penalties, and/or license suspension or revocation.

We are subject to periodic inspections by regulatory authorities, including the FDA, the USDA and the U.S. Fish and Wildlife Service. As part of these inspections, the regulatory authorities seek to determine whether our facilities, operations and animal research model importation practices comply with applicable laws and regulations. Adverse findings as a result of these inspections could lead to enforcement actions, including substantial fines, warning letters that require corrective action (including potential facilities improvement requirements), revocation of approvals, exclusion from future participation in government healthcare programs, criminal prosecution and even the denial of the right to conduct business. Envigo’s Cumberland, VA facility, which was closed as of September 30, 2022, had been the subject of inspections by the USDA, a search and seizure warrant executed by the U.S. Department of Justice (the “DOJ”) and federal and state law enforcement agents. Further, certain employees also received a grand jury subpoena requested by the U.S. Attorney’s Office for the Western District of Virginia, and the Company has received additional subpoenas related to this matter. For further information on these and other actions, see Note 16 - Contingencies to the consolidated financial statements contained in Part II, Item 8.

Inspections, investigations and/or other actions could result in penalties that could include a temporary restraining order or injunction, civil and/or criminal penalties, and/or license suspension or revocation. The imposition of any of these penalties or other restrictions on our business could adversely affect our business reputation and could have a material adverse impact on our financial condition, results of operations and stock price.

We are subject to environmental, health and safety requirements and risks as a result of which we may incur significant costs, liabilities and obligations.

We are subject to a variety of federal, state, local and foreign environmental laws, regulations, initiatives and permits that govern, among other things: the emission and discharge of materials, including greenhouse gases, in air, land and water; the remediation of soil, surface water and groundwater contamination; the generation, storage, handling, use, disposal and transportation of regulated materials and wastes, including biomedical and radioactive wastes; and health and safety. Failure to comply with these laws, regulations or permits could result in fines or sanctions, obligations to investigate or remediate existing or potential contamination, third-party property damage claims, personal injury claims, natural resource damages claims or modification or revocation of operating permits and may lead to temporary or permanent business interruptions. Pursuant to certain environmental laws, we may be held strictly, and under certain circumstances jointly and severally, liable for costs of investigation and remediation of contaminated sites which we currently own or operate, or sites we or our predecessors have owned or operated in the past. Further, we could be held liable at sites where we have sent waste for disposal.

Environmental laws, regulations and permits, and the enforcement thereof, change frequently and have tended to become more stringent over time. Compliance with the requirements of laws and regulations may increase capital costs and operating expenses or necessitate changes to our production processes.

We use, and in the past have used, hazardous materials and generate, and in the past have generated, hazardous wastes. We cannot eliminate the risk of accidental contamination or injury from these materials. In the event of such an accident, we could be held liable for any resulting damages and incur liabilities which could exceed our resources. Our costs, liabilities and obligations relating to environmental matters may have a material adverse effect on our business, financial condition, prospects, results of operations and cash flows.

Any failure by us to comply with existing regulations could harm our reputation and operating results, and requirements to comply with new laws, regulations and guidance may have an adverse effect on our financial condition and results of operations.

Any failure on our part to comply with existing regulations could result in the termination of ongoing research or the disqualification of data for submission to regulatory authorities. For example, if we were to fail to properly monitor compliance with study protocols, the data collected could be disqualified. Under such circumstances, we may be contractually required to repeat a study at no further cost to the client, but at substantial cost to us. That development

23

Table of Contents

would harm our reputation, our prospects for future work and our operating results. The issuance of a notice from the FDA or the USDA, or other relevant authorities, based on a finding of a material violation by us of good clinical practice, good laboratory practice or good manufacturing practice requirements, animal welfare laws and regulations, or other applicable regulations could materially and adversely affect our business and financial performance. Furthermore, the cost to comply with new federal or state legislature may adversely affect our operating results.

Changes in government regulation or in practices relating to the pharmaceutical industry could change the demand for the services we provide.

Governmental agencies throughout the world, but particularly in the United States, strictly regulate the drug development process. Our business involves helping pharmaceutical and biotechnology companies comply with the regulatory drug approval process. Changes in regulation, such as a relaxation in regulatory requirements or the introduction of simplified drug approval procedures, or an increase in regulatory requirements that we may have difficulty satisfying, or that make our services less competitive, could substantially change the demand for our services and products. Also, if governments increase efforts to contain drug costs and pharmaceutical and biotechnology company profits from new drugs, or if governments impose new regulatory requirements demanding restricted use of research models for biomedical research, our clients may spend less, or slow the pace of increased spending, on research and development.

If we fail to comply with data privacy and security laws and regulations, we could face substantial penalties and our business, operations and financial condition could be adversely affected.

U.S. Department of Health and Human Services regulations under the HIPAA demand compliance with patient privacy and confidentiality requirements. We are also subject to federal, state and international data privacy and security laws and regulations that govern the collection, use, disclosure, transfer, storage, location, disposal and protection of health-related and other personal information. In addition to U.S. federal laws and regulations, a number of U.S. states have also enacted data privacy and security laws and regulations that govern the collection, use, disclosure, transfer, storage, disposal, and protection of personal information. The legislative and regulatory framework for privacy and data protection issues worldwide is rapidly evolving as countries continue to adopt privacy and data security laws that may apply to us, both because our operations are located in those countries and/or because we provide services to customers in those countries. The interpretation and enforcement of the laws and regulations described above are uncertain and subject to change, and may require substantial costs to monitor and implement compliance with any additional requirements. Failure to comply with U.S. and international data protection laws and regulations, and the disclosure of any data or related breach, could result in government enforcement actions (which could include substantial civil and/or criminal penalties and injunctive relief), private litigation and/or adverse publicity and could have a material adverse impact on our business, financial condition or results of operations.

Risks Related to our Financial Activities

We have experienced periods of losses and financial insecurity.

Throughout our history we have experienced periods of financial losses and financial hardship. Our current efforts may not result in profitability, or if our efforts result in profits, such profits may not continue for any meaningful period of time. In order to finance various acquisitions and expand certain facilities, we have significantly increased our leverage. Sustained losses may result in our inability to service our financial obligations as they come due, including the additional indebtedness we have incurred to support our growth initiatives, or to meaningfully invest in our business.

We have incurred significant additional indebtedness during recent periods, which may impair our ability to raise further capital or impact our ability to service our debt.

We have incurred significant additional indebtedness during recent periods. Our additional indebtedness may impair our ability to raise further capital, including to expand our business, pursue strategic investments, and take advantage of financing or other opportunities that we believe to be in the best interests of the Company and our shareholders.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and

24

Table of Contents

make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, curtailing spend, restructuring debt, or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. Our additional indebtedness may also impact our ability to service our debt and to comply with financial covenants and the other terms of our relevant credit arrangements, in which case our lenders might pursue available remedies up to and including terminating our credit arrangements and foreclosing on available collateral.

Our credit agreement contains covenants that restrict our business and financing activities. All of our assets secure our obligations under the credit agreement and may be subject to foreclosure.

We are party to a Credit Agreement with Jefferies Finance LLC, as administrative agent, and the lenders party thereto (as amended, the “Credit Agreement”). The Credit Agreement contains various covenants, restrictions, and events of default. Among other things, these provisions require us to maintain certain financial ratios, including a secured leverage ratio and a fixed charge coverage ratio, and impose certain limits on our ability to engage in certain activities. The Third Amendment to the Credit Agreement that we entered into on January 9, 2023, imposes additional limitations on us through the date that we deliver financial statements for the quarter ending March 31, 2024, including restrictions on permitted asset sales, a prohibition on making permitted acquisitions, and significant limitations on the ability to incur additional debt, make investments and make restricted payments. Further during that time, we can only use borrowings under the revolving credit facility to fund operational expenses in the ordinary course.

The restrictions in the Credit Agreement, including under the Third Amendment, impose operating and financial restrictions on us and may limit our ability to compete effectively, take advantage of new business opportunities, or take other actions that may be in our, or our shareholders’, best interests. Further, various risks and uncertainties, including those arising as a result of the USAO-SDFL criminally charging employees of the Company’s principal supplier of NHPs, along with two Cambodian government officials, may impact our ability to comply with our obligations under the Credit Agreement.

Our obligations under the Credit Agreement are secured by all assets (other than certain excluded assets) of the Company and each of the subsidiary guarantors.

Our inability to comply with any of the provisions of the Credit Agreement could result in a default under it. If such a default occurs, the lenders may elect to declare all borrowings outstanding, together with accrued interest and other fees, to be immediately due and payable, and they would have the right to terminate any commitments to provide further funds. If we are unable to repay outstanding borrowings when due, the lenders also have the right to proceed against the collateral. The occurrence of any of these events could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Our failure to comply with the terms of our Credit Agreement could result in an event of default that could materially adversely affect our business, financial condition and results of operations.

If there were an event of default under our Credit Agreement, all amounts outstanding under that agreement could be due and payable immediately, which may have an adverse impact on our business, financial condition and results of operations. An event of default may occur should our assets or cash flow be insufficient to fully repay borrowings under our Credit Agreement, whether paid in the ordinary course or accelerated, or if we are unable to maintain compliance with relevant obligations thereunder, including financial and other covenants. Various risks and uncertainties, including those arising as a result of the USAO-SDFL criminally charging employees of the principal supplier of non-human primates to the Company, along with two Cambodian government officials, may impact our ability to comply with our obligations under the Credit Agreement.

Our management concluded that our disclosure controls and procedures and our internal control over financial reporting were not effective as of September 30, 2023 and 2022 due to material weaknesses in internal control over financial reporting. If we are unable to remediate these material weaknesses and maintain an effective system of disclosure controls and procedures and internal control over financial reporting, we may not be able to accurately

25

Table of Contents

report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our business and financial results.

Our management concluded that our disclosure controls and procedures and our internal control over financial reporting were not effective as of September 30, 2023 and 2022:

•Management did not design and maintain effective controls over information technology general controls (ITGCs) for all applications that are relevant to the preparation of the consolidated financial statements throughout the year ended September 30, 2022, which resulted in ineffective business process controls (automated and IT-dependent manual controls) that could result in misstatements potentially impacting all of the financial statement accounts and disclosures. Specifically, management did not design and maintain: sufficient user access controls to ensure appropriate segregation of duties and adequately restrict user and privileged access to financial applications, programs and data to appropriate Company personnel; and program change management controls to ensure that information technology (“IT”) program and data changes affecting financial information technology applications and underlying accounting records are authorized, tested, and implemented appropriately. As a result, business process controls (automated and IT-dependent manual controls) that are dependent on the ineffective ITGCs, or that use data produced from systems impacted by the ineffective ITGCs were deemed ineffective at September 30, 2022, and were not remediated and therefore remained ineffective at September 30, 2023; and

•Management did not have an adequate process in place to design and test the operating effectiveness of internal control over financial reporting in a timely manner or an adequate process in place to monitor and provide oversight over the completion of its assessment of internal control over financial reporting. As such, we determined that management did not effectively design and implement components of the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO framework) to address all relevant risks of material misstatement, including elements of the control environment, information and communication, control activities and monitoring activities components, relating to: (i) providing sufficient and timely management oversight and ownership over the internal control evaluation process; (ii) hiring and training sufficient personnel to timely support the Company’s internal control objectives; and (iii) performing timely monitoring and oversight to ascertain whether the components of internal control are present and functioning effectively. As a result, controls relevant to all business processes and related controls (including relevant entity level controls) were deemed ineffective at September 30, 2022, and were not remediated and therefore remained ineffective at September 30, 2023.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected and corrected on a timely basis. Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. We expect to take steps to remediate the material weaknesses, but there is no assurance that any remediation efforts will ultimately have the intended effects.

If we identify any new material weaknesses in the future, any such newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.

Risks Related to our Operations

We rely on a limited number of key clients, the importance of which may vary dramatically from year to year, and a loss of one or more of these key clients may adversely affect our operating results.

One client related to the RMS segment accounted for approximately 22.0% and 28.2% of our total revenue during fiscal years 2023 and 2022, respectively. Five clients of the DSA segment in the aggregate accounted for approximately 5.4% and 7.2% of our total revenue during fiscal years 2023 and 2022, respectively. The loss of a significant amount of business from one or more of our major clients would materially and adversely affect our results of operations until such time, if ever, as we are able to replace the lost business. Significant clients or projects in any

26

Table of Contents

one period may not continue to be significant clients or projects in other periods. In any given year, there is a possibility that a single client may account for a significant percentage of our total revenue or that our business may depend on one or more large projects. Since we do not have long-term contracts with most of our clients, the importance of a single client may vary dramatically from year to year as projects end and new projects begin. To the extent that we are meaningfully dependent on any single client, we are indirectly subject to risks related to that client, including if such risks impede the client’s ability to stay in business or otherwise to make timely payments to us.

We operate in a highly competitive industry.

The CRO services industry is highly competitive. We often compete for business not only with other CROs, but also with internal discovery and development departments within our client companies. Several of our competitors have significantly greater financial, marketing, technical or other resources and a larger global footprint than we have. The industry has historically been diverse with more than 1,000 CROs around the globe, ranging from small, regional niche laboratories up to global comprehensive service providers with tens of thousands of employees.

The CRO industry has experienced consolidation in recent years. This trend is likely to produce more competition among the larger companies for both clients and acquisition candidates. Offshore CROs have provided increasing competitive pressures.

The RMS industry is highly competitive. Competition ranges from academics and large biopharmaceutical companies, that derive and maintain their own rodent colonies, to commercial competitors that may offer a similar or overlapping range of products and/or services. Some of these competitors have greater capital, technical and other resources than we have, while other competitors that are smaller specialized companies might compete effectively against us based on price and their concentrated size and focus.

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 majority of our clients’ contracts and orders can be terminated upon short notice.

Most of our contracts for CRO services are terminable by the client upon 30 days’ notice and these clients terminate or delay their contracts for a variety of reasons. Further, in general, our clients order research models on an as-needed basis. The size and frequency of those orders can be reduced or eliminated with little or no notice.

Client contracts and orders may be negatively impacted for various reasons, including:

•products being tested fail to satisfy safety requirements;

•products having undesired clinical results;

•the client deciding to forego a particular study;

•inability to enroll enough patients in the study;

•inability to recruit enough investigators;

•loss of funding for the particular research study or program;

•production problems causing shortages of the drug;

•inability to secure research models relevant to the studies; and

•actions by regulatory authorities.

Although our CRO contracts frequently entitle us to receive the costs of winding down the terminated projects, as well as all fees earned by us up to the time of termination, and some of our contracts entitle us to a termination fee, the loss, reduction in scope or delay of a large contract or order, or the loss or delay of multiple contracts or orders, could materially adversely affect our business.

27

Table of Contents

We may bear financial risk if we underprice our contracts or overrun cost estimates.

Since some of our contracts are structured as fixed price or fee-for-service, we bear the financial risk if we initially underprice our contracts or otherwise overrun our cost estimates. Significant underpricing or cost overruns could have a material adverse effect on our business, results of operations, financial condition, and cash flows.

Our business uses biological and hazardous materials, which could injure people or violate laws, resulting in liability that could adversely impact our financial condition and business.

Our activities involve the controlled use of potentially harmful biological materials, as well as hazardous materials, chemicals and various radioactive compounds. We cannot completely eliminate the risk of accidental contamination or injury from the use, storage, handling or disposal of these materials. In the event of contamination or injury, we could be held liable for damages that result, and any liability could exceed our insurance coverage and ability to pay. Any contamination or injury could also damage our reputation, which is critical to obtaining new business. In addition, we are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with these laws and regulations is significant and if changes are made to impose additional requirements, these costs could increase and have an adverse impact on our financial condition and results of operations.

Our animal populations may suffer diseases that can damage our inventory, harm our reputation, result in decreased sales of our services or research products or result in other liability.

It is important that our animal populations be free of diseases, including infectious diseases. The presence and prevalence of diseases can distort or compromise the quality of research results, can cause substantial loss of animals in our inventory, can result in harm to humans or outside animal populations if the disease is not contained to animals in inventory, or can result in other losses.

These risks may differ substantially according to species. In rodents, most infections are without any apparent clinical signs and therefore pose a risk to the scientific quality of the research performed on the animals rather than to humans. The same applies to primates, where all animals are serologically tested for specific diseases in our facilities and at our suppliers. The main concern in this species is the potential for zoonotic infectious disease-causing harm to humans. We seek to minimize the risk of these species being infected by stringent biohazard management protocols and health monitoring programs in place in our facilities. Nevertheless, we have in the past suffered disease in our animal populations and may suffer outbreaks in the future.

If disease or contamination occurs in our animal population, it typically requires remediation and cleanup activities that are costly and time consuming. In certain circumstances, it can require the temporary or permanent closure of an affected facility. We have experienced such closures in the past and may do so again in the future.

Any significant disease outbreak has the potential to harm our reputation or have a material adverse effect on our financial condition, results of operations, and cash flows. There is also the risk that disease from research models we produce may affect our clients’ facilities and may result in an affected client requesting compensation for damages.

While we endeavor to include provisions in our sale and supply contracts which entitle us to be indemnified or entitle us to a limitation of liability, these provisions do not uniformly protect us against liability arising from certain of our own actions, such as negligence or misconduct. Moreover, in certain circumstances, we may agree to use contracts drafted by our clients, which may not contain clauses that indemnify us or limit our liability. We could be materially adversely affected if we were required to pay damages or bear the costs of defending any claim which is not covered by a contractual indemnification provision or in the event that a party who must indemnify us does not fulfill its indemnification obligations or which is beyond the level of our insurance coverage or for which insurance coverage is not available. There can be no assurance that we will be able to maintain insurance coverage on terms acceptable to us.

Failure to manage our growth effectively could cause our business to suffer and have an adverse effect on our business, operating results and financial condition.

We experienced significant growth in a short period of time, including as a result of the Envigo acquisition. To manage our growth effectively, we must continually evaluate and evolve our organization. We must also manage our employees, operations, finances, technology and development and capital investments efficiently. Our efficiency,

28

Table of Contents

productivity and the quality of our products and services may be adversely impacted if we do not integrate and manage our growth effectively, or if we fail to appropriately coordinate across our organization.

Additionally, our rapid growth may place a strain on our resources, infrastructure and ability to maintain the quality of our products and services. You should not consider our revenue growth and levels of profitability in recent periods as indicative of future performance. In future periods, our revenue or profitability could decline or grow more slowly than we expect. Failure to manage our growth effectively could cause our business to suffer and have an adverse effect on our operating results and financial condition.

Providing CRO services creates a risk of liability.

We could be held liable for errors and omissions in connection with the services we perform. In certain circumstances, we seek to manage our liability risk through contractual provisions with clients requiring indemnification by the clients or coverage under the clients’ product liability insurance policies. The financial performance of our client indemnifying parties is not secured. Therefore, we bear the risk that the indemnifying party may not have the financial ability, or may otherwise fail, to fulfill its indemnification obligations or that the liability could exceed the amount of applicable client insurance, if any. In the event that we are unable to reach indemnification or insurance coverage arrangements with our clients to appropriately cover our potential losses, our insurance coverage may not adequately cover such losses. Relevant insurance coverage may also not always be available to us on acceptable terms or at all.

New technologies may be developed, validated and increasingly used in biomedical research that could reduce demand for some of our products and services.

For many years, groups within the scientific and research communities have attempted to develop models, methods and systems that would replace or supplement the use of living animals as test subjects in biomedical research. In addition, technological improvements to existing or new processes, such as imaging and biomarker technology, could result in a refinement in the number of animal research models necessary to conduct the required research. Alternative research methods could decrease the need for research models, and we may not be able to develop new products effectively or in a timely manner to replace any lost sales. In addition, other companies or entities may develop research models with characteristics different than the ones that we produce, and which may be viewed as more desirable by our clients.

Our non-U.S. locations account for a significant percentage of our revenues, exposing us to risks associated with operating internationally.

During the fiscal years ended September 30, 2023 and 2022, 15.7% and 13.8%, respectively, of our revenues were generated by our facilities outside the U.S. As a result of these sales from foreign entities and facilities located outside the U.S., our operations are subject to a variety of risks unique to international operations, including the following:

•exposure to local economic conditions;

•currency exchange rate and interest rate fluctuations;

•differences and changes in tax laws;

•potential restrictions on the transfer of funds;

•differences in regulatory requirements;

•exposure to liabilities under the U.S. Foreign Corrupt Practices Act or the U.K. Antibribery Act;

•government imposed investment and other restrictions or requirements;

•failure to comply with new and evolving regulations, including privacy and security laws

•exposure to local social unrest, including any resulting acts of war, terrorism or similar events;

•exposure to local public health issues and the resulting impact on economic and political conditions;

•difficulty enforcing agreements and collecting receivables through certain legal systems;

•more expansive legal rights of employees, including specifically those applicable to our European operations;

•variations in protection of intellectual property and other legal rights; and

•export and import and trade restrictions (such as antidumping duties, tariffs or embargoes).

Some of our clients and contracts depend on government funding of research and development and a reduction in that funding may adversely affect our business.

A significant portion of sales are derived from clients at academic institutions and research laboratories whose funding is partially dependent on funding from government sources, including the NIH and U.K./E.U. equivalents. Such funding can be difficult to forecast as it may be subject to the political process. Our sales may be adversely affected if our clients delay purchases as a result of uncertainties surrounding the approval of government budget proposals. There can be no certainty that government research funding that is approved will be directed towards projects and studies that require use of our products and services. A reduction in government funding for the NIH or other government research agencies could adversely affect our business and our financial results.

Risks Related to our Acquisition and Optimization Activities

We have and may further expand our business through acquisitions, which exposes us to various risks. Our due diligence of our past or future acquisitions may not have identified all pertinent risks, or the full magnitude of such risks, which could materially affect our business, financial condition, liquidity and results of operations.

We have completed several acquisitions and from time to time review other acquisition candidates. Factors which may affect our ability to effectively pursue acquisition targets or to grow successfully through completed acquisitions, including our recent acquisitions, include:

•The inability of the Company to obtain financing for the acquisition of targets;

•Difficulties and expenses in connection with integrating acquired companies and achieving expected benefits, including as related to the integration of departments, accounting and other systems, technologies, books and records and procedures;

•Diversion of management’s attention from daily operations to various integration activities;

•The potential for disruption of prior operations and plans;

•The risk that acquisitions could be dilutive to earnings, or in the event of acquisitions made through the issuance of our common shares to the shareholders of the acquired company, dilutive to the percentage ownership of our existing stockholders;

•The possibility that we may be adversely affected by risks facing the acquired companies, including potential losses resulting from undiscovered liabilities of acquired companies not covered by the indemnification we may obtain from the sellers;

•Risks associated with the assimilation and retention of employees, including key employees;

•The potential loss of, or adverse effects on, existing business relationships the acquired business has with suppliers and clients;

•The potential need to address relevant internal control over financial reporting and disclosure control and procedures matters;

•Possible deficiencies in operational processes and procedures;

•Risks associated with carrying a relatively significant level of debt; and

•The ability of our management team to manage expanded operations to meet operational and financial expectations.

Our operating results or financial condition also may be adversely impacted by (i) claims or liabilities related to the acquired companies’ businesses including, among others, claims from U.S. regulatory or other governmental agencies, such as those related to OBRC and Envigo, terminated employees, current or former clients or business partners, or other third parties; (ii) pre-existing contractual relationships of the acquired companies that we would not have otherwise entered into, the termination or modification of which may be costly or disruptive to our business; (iii) unfavorable accounting treatment as a result of the acquired companies' practices; and (iv) intellectual property claims or disputes.

Table of Contents

Certain of the companies we have acquired were not required to maintain an internal control infrastructure that would meet the standards of a public company, including the requirements of the Sarbanes-Oxley Act of 2002, and we may acquire similar companies in the future. The costs to implement such controls and procedures may be substantial and we could encounter unexpected delays and challenges in this implementation. In addition, we may discover significant deficiencies or material weaknesses in the quality of an acquired company's financial and disclosure controls and procedures which could result in additional costs or adversely affect our business or operating results, and, as has occurred with us, the accounting for acquisitions can be complex and may lead to material weaknesses.

As part of our merger and acquisition due diligence, we utilize information provided by relevant sellers. As is true with any merger and acquisition transaction, we may not be aware of all liabilities, or the full magnitude of liabilities, of the acquired business at the time of acquisition. Potential incremental liabilities and additional risks and uncertainties related to our recent or future acquisitions not known or fully appreciated by us could negatively and materially impact our future business, financial condition and results of operations. For example, there are a number of investigations, lawsuits, claims and other matters described in Note 16 – Contingencies that relate to the businesses and operations we acquired through the acquisitions of Envigo, OBRC and others.

We may need additional capital, and any additional capital we seek may not be available in the amount or at the time we need it.

Successful execution of our growth plans will require that we have access to capital. Our expected financing needs are based upon management’s estimates as to future revenue and expense. Our business plan and financing needs are subject to change based upon, among other factors, our ability to increase revenues and manage expenses and the timing and extent of our future capital expenditures and acquisition activity. If our estimates of our financing needs change, we may need additional capital more quickly than we expect or we may need a greater amount of capital.

In general, additional capital may be raised through the sale of common shares, preferred equity or convertible debt securities, entry into debt facilities or other third-party funding arrangements. The sale of equity and convertible debt securities may result in dilution to our shareholders and those securities may have rights senior to those of our common shares. Agreements entered into in connection with such capital raising activities could contain covenants that would restrict our operations or require us to relinquish certain rights. Additional capital may not be available on reasonable terms, or at all. If we cannot timely raise any needed funds, we may be forced to reduce our operating expenses, which could adversely affect our ability to implement our long-term strategic roadmap and grow our business.

The Company may fail to realize anticipated strategic and financial benefits from acquisitions, related integrations and our site optimization strategy.

We may not realize all of the anticipated benefits of our business acquisitions. These acquisitions may not further our business strategy as we expect, we may fail to successfully integrate the acquired operations as planned or to realize the synergies and other benefits we expected from the acquisitions, we may experience unexpected adverse impacts on the acquired businesses, or we may otherwise not realize the expected return on our investments, any of which could adversely affect our business or operating results and potentially cause impairment to assets that we record as a part of the acquisitions, including intangible assets and goodwill. We may have difficulties managing the acquired businesses or retaining key personnel of the acquired companies.

In addition, during recent periods, we have undertaken restructuring and site optimization initiatives, designed to allow us to reduce overhead and create efficiencies through scale. We are also currently working to take in-house the North American transportation services previously provided by a third party. These initiatives present significant risks that may impair our ability to achieve anticipated operating enhancements and/or cost reductions, or otherwise harm our business, including higher than anticipated costs in implementing these initiatives, asset impairments and management distraction. If we fail to achieve some or all of the expected benefits of these initiatives, it could have a material adverse effect on our competitive position, business, financial condition, results of operations and cash flows.

Risks Related to the Industries we Serve

We are substantially dependent on the pharmaceutical and biotechnology industries.

Our revenues depend greatly on the expenditures made by pharmaceutical and biotechnology companies in research and development, including their decisions to outsource drug development services to providers like us, rather than

31

Table of Contents

handling such services in-house. In some instances, companies in these industries are reliant on their ability to raise capital in order to fund their research and development projects and to compensate us for services rendered.

Fluctuations in the research and development budgets of researchers and their organizations has, had and could continue to have a significant effect on the demand for our products and services. Research and development budgets fluctuate due to changes in available resources, mergers of pharmaceutical and biotechnology companies, spending priorities and institutional budgetary policies, among other reasons. Accordingly, economic factors and industry trends that affect our clients in these industries also affect our business. Our ability to continue to grow and win new business depends in large part upon the ability and willingness of the pharmaceutical and biotechnology industries to continue to spend on research and development and to purchase the products and outsource the services we provide. If companies in these industries were to reduce the number or scope of research and development projects they conduct or outsource, our business could be materially adversely affected. We believe this occurred to some extent is fiscal year 2023 and could continue.

Risks Related to Research and Development

Our future success depends on our ability to keep pace with rapid technological changes that could make our services and products less competitive or obsolete.

The biotechnology, pharmaceutical and medical device industries generally, and contract research services more specifically, are subject to increasingly rapid technological changes. 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 our counterparts to remain competitive, our competitive position, and in turn our business, revenues and financial condition, would be materially and adversely affected. Many of our competitors have superior financial and human resources deployed toward research and development efforts. Our relatively constrained financial and human resources may limit our ability to effectively keep pace with relevant technological changes.

Actions of animal rights activists may affect our business.

Products and services of the type we provide are required for the registration of pharmaceutical products under regulatory auspices in the United States, Europe and other countries. Many CROs, animal breeders, biopharmaceutical companies and other research organizations have been targeted by animal rights activists that oppose all testing on animals, for whatever purpose, including the animal testing activities in support of safety and efficacy testing for drug development. These groups, which include groups directed at the industry and us, have publicly stated that the goal of their campaign is to stop animal testing. Acts of vandalism and other acts by animal rights activists who object to the use of animals in product development could have a material adverse effect on our business. These groups have historically targeted CROs, animal breeders, academic institutions and biopharmaceutical companies, but also third parties that do business with those organizations, including clients, suppliers, advisors, financial advisors, lenders and investors.

Risks Related to Technology and Cybersecurity

We are at risk of cyber-attacks or other security breaches that could compromise sensitive business information, undermine our ability to operate effectively and expose us to liability, which could cause our business and reputation to suffer.

Cyber-attacks or security breaches could compromise confidential information of ours, our employees and our clients, cause a disruption in our operations, harm our reputation and expose us to liability, which in turn could negatively impact our business and the value of our common shares. As a routine element of our business, we collect, analyze, and retain substantial amounts of data pertaining to the clinical and non-clinical studies we conduct for our clients. We also maintain other sensitive client information, information regarding intellectual property related to certain of our products and other business-critical information, including personally identifiable information of our employees. Our employees, some of whom have access to such information, have and will likely continue to receive “phishing” e-mails intended to trick recipients into surrendering their usernames and passwords and/or inadvertently installing malicious software onto their computers or networks they are connected to. We cannot completely protect against the

32

Table of Contents

possibility that sensitive information may be accessed, publicly disclosed, lost or stolen, via phishing attempts or other circumstances.

We utilize cybersecurity technologies, processes and practices which are designed to protect our networks, computers, programs and data from attack, damage or unauthorized access, but they may not be effective or work as designed. Our contracts with our clients typically contain provisions that require us to keep confidential the information generated from our studies. A cyber-attack could result in a breach of those provisions or other negative outcomes, including legal claims or proceedings, investigations, potential liabilities under laws that protect the privacy of personal information, delays and other impediments to our clients’ discovery and development efforts, ransomware demands and related delays, damage to our reputation and a negative impact on our financial results and the value of our common shares.

Hardware or software failures, delays in the operations of our computer and communications systems or the failure to implement system enhancements could harm our business.

We operate large and complex computer systems that contain significant amounts of client data. Our success depends on the efficient and uninterrupted operation of our computer and communications systems. A failure of our network or data gathering procedures could impede the processing of data, delivery of databases and services, client orders, product shipments and day-to-day management of our business and could result in the corruption or loss of data. While we have disaster recovery plans in place for our operations, they might not adequately protect us. Damage from fire, floods, hurricanes, power loss, telecommunications failures, computer viruses, break-ins and similar events at our facilities could result in interruptions in the flow of data to our servers and from our servers to our clients. In addition, any failure by our computer environment to provide our required data communications capacity could result in interruptions in our service. In the event of a delay in the delivery of data, we could be required to transfer our data collection operations to an alternative provider of server hosting services, which may not be available on terms favorable to us or on a timely basis, and could result in delays in our ability to deliver our products and services to our clients. Additionally, significant delays in the planned delivery of system enhancements, improvements and inadequate performance of the systems once they are completed could harm our business. Finally, long-term disruptions in our computer and communications infrastructure caused by events such as natural disasters, the outbreak of war, the escalation of hostilities and acts of terrorism, particularly involving cities in which we have offices, could adversely affect our businesses. Our property and business interruption insurance coverage might not be adequate to compensate us for all losses that may occur.

Risks Related to Health Emergencies

Our business, results of operations, financial condition, including the carrying value of certain of our assets, cash flows and stock price have and may continue to be adversely affected by pandemics, epidemics or other public health emergencies.

Our business, results of operations, financial condition, including the carrying value of certain of our assets, cash flows and stock price have and may continue to be adversely affected by pandemics, epidemics or other public health emergencies. Such health emergencies can result in governments around the world implementing stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments, school closures, and other measures.

The outbreak of public health emergencies and preventive or protective actions taken by governmental authorities may continue to have a material adverse effect on our and our clients’ and suppliers’ respective operations, including with respect to the potential for business shutdowns or disruptions. The extent to which these health emergencies may continue to adversely impact our business depends on future developments, which are highly uncertain and unpredictable, depending upon the severity and duration of the emergency and the effectiveness of actions taken globally to contain or mitigate its effects. Future financial impact cannot be estimated reasonably at this time, but may materially adversely affect our business, results of operations, financial condition, including the carrying value of certain of our assets, and cash flows. Even after public health emergencies have subsided, we may experience materially adverse impacts to our business due to any resulting economic recession or depression and demand for our products and services. Additionally, concerns over the economic impact of public health emergencies have caused extreme volatility in financial and other capital markets which has and may in the future adversely impact our stock price and our ability to access capital markets including to refinance existing obligations. To the extent public health

33

Table of Contents

emergencies adversely affect our business and financial results, they may also have the effect of exacerbating many of the other risks described herein or other risks not presently known to us or that we currently deem immaterial.

Risks Related to Share Ownership

Our share price could continue to be volatile and our trading volume may fluctuate substantially.

The market price of our common shares has historically been and might continue to be volatile. Many factors may have a significant impact on the future price of our common shares, including:

•our failure to successfully implement our business objectives;

•our businesses, operations, results and prospects;

•changes in revenue or earnings estimates, or changes in recommendations by equity research analysts;

•compliance with ongoing regulatory requirements;

•market acceptance of our products;

•technological innovations, new commercial products or drug discovery efforts and preclinical and clinical activities by us or our competitors;

•changes in government regulations, taxes, legal proceedings and other developments;

•inspections, investigations and enforcement actions by regulatory authorities against us or our principal suppliers;

•negative information related to, or adverse regulatory or other actions against us or our principal suppliers;

•pandemics, epidemics or other public health emergencies, such as COVID-19;

•general economic conditions, including changes in interest rates, and other external factors;

•actual or anticipated fluctuations in our quarterly financial and operating results and those of our competitors;

•announcements concerning us or our competitors;

•market conditions in CRO or research model industries;

•additions or departures of key management personnel;

•future mergers and strategic alliances;

•investor sentiment toward the stock of animal breeding companies;

•maintenance of acceptable credit ratings or credit quality;

•ability to fund future growth;

•the degree of trading liquidity in our common shares; and

•our ability to meet the minimum standards required for remaining listed on The Nasdaq Capital Market.

Factors which may impact the price of our common shares include influences beyond our control, such as market conditions and changes in the pharmaceutical and biotechnology industries we serve. The stock market, and in particular the market for pharmaceutical and biotechnology company stocks, has experienced periods of significant price and volume fluctuations, including as a result of recent increases in interest rates and inflation. Volatility and valuation decline have affected the market prices of securities issued by many companies, often for reasons unrelated to their operating performance, and might adversely affect the price of our common shares.

Following periods of volatility in the overall market and in the market price of a company’s securities, securities class action litigation and derivative securities litigation have often been instituted against that company, as has been the case with us. Such occurrences of litigation could result in very substantial costs, divert management’s attention and resources and harm our business, operating results and financial condition.

34

Table of Contents

Our principal shareholders and management own a significant percentage of our stock and will be able to exercise significant influence over matters subject to shareholder approval.

As of November 30, 2023, our executive officers, directors and 5% shareholders beneficially owned approximately 10.3% of our outstanding shares of capital stock. In addition, as of November 30, 2023, our executive officers and directors held options to purchase an aggregate of 360,908 of our common shares at a weighted-average exercise price of $6.38 per share and an aggregate of 723,515 unvested restricted stock units. Therefore, these shareholders will have the ability to influence us through this ownership position. The interests of this group of shareholders may not coincide with the interests of other shareholders.

The resale of certain shares issued in the Envigo acquisition and covered by a resale registration statement could adversely affect the market price of our common shares, which result could in turn negatively affect our ability to raise additional equity capital.

Pursuant to the Shareholders Agreement which we entered with certain former shareholders of Envigo in connection with the Envigo acquisition, we filed a registration statement registering the resale of 6,964,728 of our common shares held by the shareholders who are parties to the Shareholders Agreement. The resale registration statement permits the resale of these shares at any time and without restriction. The sale, or availability for sale, of our common shares in the public market may adversely affect the prevailing market price of our common shares and may impair our ability to raise additional equity capital. The resale of a substantial number of our common shares in the public market could adversely affect the market price for our common shares and make it more difficult for you to sell our common shares at times and prices that you feel are appropriate. Furthermore, because there are a large number of shares registered pursuant to the resale registration statement, the selling shareholders named in such registration statement may continue to offer shares covered by the resale registration statement for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to the resale registration statement may continue for an extended period of time and continued negative pressure on the market price of our common shares could have a material adverse effect on our ability to raise additional equity capital.

Anti-takeover provisions in our organizational documents and under Indiana law may discourage or prevent a change in control, even if a sale of us would benefit our shareholders, which could cause our stock price to decline and prevent attempts by shareholders to replace or remove our current management.

Our Second Amended and Restated Articles of Incorporation and Third Amended and Restated Bylaws contain provisions that may delay or prevent a change in control, discourage bids at a premium over the market price of our common shares, harm the market price of our common shares, and diminish the voting and other rights of the holders of our common shares. These provisions include:

•dividing our board of directors into three classes serving staggered three-year terms;

•authorizing our board of directors to issue preferred stock and additional common shares without shareholder approval;

•requiring one or more written demands signed and dated by holders of at least 25% of all the votes entitled to be cast on any issue proposed to be considered at a special meeting for shareholders to call a special meeting;

•prohibiting our shareholders from amending our Bylaws; and

•requiring advance notice for nominating directors at shareholders’ meetings.

Our board of directors also has the ability to adopt a shareholder rights agreement, sometimes called a “poison pill,” providing for the issuance of a new series of preferred stock to holders of common shares. In the event of a takeover attempt, this preferred stock would give rights to holders of common shares (other than the potential acquirer) to buy additional common shares at a discount, leading to the dilution of the potential acquirer’s stake. The board’s ability to adopt a poison pill may discourage potential takeover offers, particularly by suitors the board may view as unfavorable transaction partners.

As an Indiana corporation, we are governed by the Indiana Business Corporation Law (as amended from time to time, the “IBCL”). Under specified circumstances, certain provisions of the IBCL related to control share acquisitions, business combinations, and constituent interests may delay, prevent, or make more difficult unsolicited acquisitions or

35

Table of Contents

changes of control. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish Company transactions that shareholders might deem to be in their best interest.

If we are unable to maintain listing of our securities on The Nasdaq Capital Market or another reputable stock exchange, it may be more difficult for our shareholders to sell their securities.

Nasdaq requires listed issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, Nasdaq should delist our securities from trading on its exchange and we are unable to obtain listing on another reputable national securities exchange, a reduction in some or all of the following may occur, each of which could materially adversely affect our shareholders:

•the liquidity of our common shares;

•the market price of our common shares;

•our ability to obtain financing for the continuation of our operations;

•the number of institutional and general investors that will consider investing in our common shares;

•the number of market makers in our common shares;

•the availability of information concerning the trading prices and volume of our common shares; and

•the number of broker-dealers willing to execute trades in our common shares.

General Risk Factors

The loss of key personnel could adversely affect our business.

Our success depends to a significant extent upon the efforts of our senior management team and other key personnel. The loss of the services of such personnel could adversely affect our business. Also, because of the nature of our business, our success depends upon our ability to attract, train, manage and retain qualified personnel. There is substantial competition for qualified personnel, and an inability to recruit or retain qualified personnel may impact our ability to grow our business and compete effectively in our industry.

We rely on third parties for important services.

We have historically depended on third parties to provide us with services critical to our business, including without limitation transportation services. The failure of third parties to adequately provide needed services or our determination to forgo non-critical services, could have a material adverse effect on our business.

Unfavorable general economic conditions may materially adversely affect our business.

While it is difficult for us to predict the impact of general economic conditions on our business, these conditions could reduce client demand for some of our products or services, which could cause our revenue to decline. Also, our clients, particularly smaller biotechnology companies which are especially reliant on the credit and capital markets, may not be able to obtain adequate access to credit or equity funding, which could affect their ability to timely pay us. Moreover, we rely on credit facilities to provide working capital to support our operations and regularly evaluate alternative financing sources. Changes in the commercial credit market or in the financial stability of our creditors may impact the ability of our creditors to provide additional financing. In addition, the financial condition of our credit facility providers, which is beyond our control, may adversely change. Any decrease in our access to borrowings under our credit facility or successor facilities (if any), tightening of lending standards and other changes to our sources of liquidity could adversely impact our ability to obtain the financing we need to continue operating our business in the current manner. For these reasons, among others, if economic conditions stagnate or decline, our operating results and financial condition could be adversely affected.

Global economic uncertainty has produced, and continues to produce, substantial stress, volatility, illiquidity and disruption of global credit and other financial markets. Various factors contribute to the uncertain economic environment, including geopolitical tensions, military conflicts, the level and volatility of interest rates, the level of

36

inflation, the continuing effects of the COVID-19 pandemic, an actual recession or fears of a recession, trade policies and tariffs, and political and governmental instability.

Business Overview

Inotiv is a leading contract research organization ("CRO") dedicated to providing nonclinical and analytical drug discovery and development services to the pharmaceutical and medical device industries and selling a range of research-quality animals and diets to the same industries as well as academia and government clients. Our products and services enable the discovery and development of new drugs and medical devices and facilitate better understanding of disease biology, all while focusing on increasing efficiency, improving data and reducing the cost of discovering and taking new drugs and medical devices to market. Inotiv is committed to supporting discovery and development objectives as well as helping researchers realize the full potential of their critical research and development projects, all while working together to build a healthier and safer world. We are dedicated to practicing high standards of laboratory animal care and welfare.

During recent periods, we have undertaken significant internal and external growth initiatives, as well as site optimization initiatives. Our growth initiatives include acquisitions and related integrations, expansion of existing capacity and services, and startup of new services. Prior to fiscal year 2022, our growth initiatives focused on discovery and safety assessment services, and, as a result of our strategic acquisition of Envigo RMS Holding Corp. (“Envigo”) in November 2021, which added a complementary research model platform, our full spectrum solutions now span two segments: Discovery and Safety Assessment (“DSA”) and Research Models and Services (“RMS”). In addition to the growth initiatives described above, we have also undertaken site optimization initiatives through site closures and consolidation in the U.S. and Europe as further described below.

DSA

During the twelve months ended September 30, 2022, we continued building Inotiv into a comprehensive provider of preclinical drug discovery and safety assessment services through our strategic acquisitions of Plato BioPharma, Inc. (“Plato”), Integrated Laboratory Systems, LLC (“ILS”), Histion, LLC (“Histion”), Protypia, Inc. (“Protypia”) and our collaboration with Synexa Life Sciences. Plato brought us important new in vivo pharmacology capabilities, ILS complemented our BioReliance® genetic toxicology assets and accelerated the buildout of our genetic toxicology offerings as well as expanded our general rodent toxicology capacity. In addition, ILS allowed us to provide a computational toxicology service to provide predictive toxicology assessments. Histion accelerated our development and growth into the highly-specialized plastics and medical device histopathology business and Protypia enhanced our ability to support clients in the development of safe and effective medicines, particularly in the areas of immuno-oncology and cell and gene therapy by bringing bioanalytical capability to solid tissue specimens. The partnership with Synexa Life Sciences enhanced our large molecule bioanalysis and biomarker platform.

During the twelve months ended September 30, 2023, our focus for our business within the DSA segment revolved around maximizing the integration of service offerings from the aforementioned acquisitions and continuing to build out additional service capabilities and capacity. As we completed fitting out laboratory space, validating new equipment and establishing our processes, we added to the overall depth and breadth of our services portfolio, and expanded our client service capabilities, which are designed to enhance both overall quality and operating margins by reducing our reliance on third-party outsourcing. These included our Boulder, Colorado, facility expansion, which was completed in December 2022, the opening of our Kalamazoo, Michigan, pathology site in January 2023, and the buildout of our Rockville, Maryland, site, which is now operational with GLP biotherapeutics analytical and genetic toxicology capabilities. Furthermore, the expansion activities at Fort Collins, Colorado, were completed by the end of October 2023 and the expanded site is completing the validation of the facility and equipment and plans to be operational early in the second quarter of fiscal 2024. Additionally, we announced the expansion of our safety pharmacology offering with the validation and verification of a cardiopulmonary telemetry study model in cynomolgus macaques. Offered through our DSA business, telemetry

allows for the continuous observation of ECG, respiratory rate and volume, blood pressure and other cardiovascular parameters during preclinical safety studies. Additional new service offerings that we are building internally include: mechanistic pharmacology and toxicology, safety pharmacology; juvenile toxicology; SEND (Standard for the Exchange of Nonclinical Data) data reporting; clinical pathology; biotherapeutics; histopathology for devices; genetic toxicology; and cardiovascular safety pharmacology.

RMS

During the twelve months ended September 30, 2022 and following the Envigo acquisition, we took steps to leverage our existing RMS capacity with the acquisition of Robinson Services Inc.’s (“RSI”) rabbit breeding business and we acquired Orient BioResource Center, Inc. (“OBRC”), which provided access to additional non-human primate facilities. In addition to two sites that Envigo announced closing prior to our acquisition of Envigo, we announced in June 2022 that we were closing a purpose-bred canine facility in Cumberland, Virginia and a rodent breeding facility in Dublin, Virginia as part of restructuring activities. The rodent breeding operations were consolidated into an existing, recently renovated site. The Cumberland facility closure was completed in September 2022 and the Dublin facility closure was completed in November 2022.

During the twelve months ended September 30, 2023, our focus for our business within the RMS segment included navigating the global NHP market and executing on our site optimization plans. On November 16, 2022, the Company became aware that the U.S. Attorney’s Office for the Southern District of Florida (“USAO-SDFL”) had criminally charged employees of the principal supplier of NHPs to the Company, along with two Cambodian government officials, with conspiring to illegally import NHPs into the U.S. from December 2017 through January 2022 and in connection with seven specific imports between July 2018 and December 2021, (the "November 16, 2022 event"). Also, as previously disclosed, two of the Company's subsidiaries, OBRC and Envigo, have received grand jury subpoenas from USAO-SDFL requiring the production of documents and information related to their importation of NHPs into the U.S.

The Company has not been directed to refrain from selling the Cambodian NHPs in its possession in the U.S. However, due to the allegations contained in the indictment involving the supplier and the Cambodian government officials, the Company believed that it was prudent, at the time of the November 16, 2022 event, to refrain from selling or delivering any of its Cambodian NHPs held in the U.S. until the Company’s staff and external experts could evaluate what additionally could be done to satisfy itself that the NHPs in inventory from Cambodia can be reasonably determined to be purpose-bred. Historically, the Company relied on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (“CITES”) documentation and related processes and procedures, including release of each import by U.S. Fish and Wildlife Service. After a thorough review of the documentation we have for the Cambodian NHPs in our inventory and their colonies, we resumed shipping a amount of Cambodian NHPs beginning in January 2023. In addition, we completed audits on site at our Cambodian supplier and we worked to establish even more robust procedures for future imports.

Since the November 16, 2022 event, we have focused on working with our suppliers and developing a long-term solution to establish procedures we can be comfortable assuring ourselves and our customers we only provide purpose-bred NHPs from Cambodia. We have scientists inside and outside our organization working towards establishing new testing procedures for importing purpose-bred Cambodian NHPs and meeting the needs of drug discovery and development in the US. In the meantime, we continued to import from countries outside of Cambodia to satisfy demand at our DSA business segment and to our RMS clients. During fiscal 2023, the volume of NHPs we sold to our RMS clients was significantly lower than in fiscal 2022. While the lower volume was offset by an increase in the average selling price of NHPs, the average selling price of NHPs in the fourth quarter of fiscal 2023 was the lowest quarterly increase compared to each of the first three quarters of fiscal 2023.

During the first quarter of fiscal year 2023, we announced additional site consolidation plans in the U.S. and our intent to consult with employee representatives for a proposed consolidation of certain European and U.K. sites. Our site optimization plans are intended to allow us to reduce overhead and create efficiencies through scale. During fiscal 2023, we completed all planned fiscal year 2023 consolidations and closures and sold our Israeli businesses. The consolidation of the operations at our Blackthorn, U.K., facility with the operations in Hillcrest, U.K., is expected to be complete by the end of March 2024. During the fourth quarter of fiscal year 2023, we made the decision to close our Spain facility. The exit of the Spain facility was complete as of September 30, 2023 and we sold the Spain facility in November 2023. Refer to Note 11 – Restructuring and Assets Held for Sale to our consolidated financial statements contained in Part II, Item 8 for more information related to the site consolidation plans.

These improvements included investments in our information technology platforms, building program management functions to enhance management and communication with clients and multi-site programs, further enhancing client services and improving the client experience. We believe the actions taken and investments made in recent periods form a solid foundation upon which we can continue to build.

For the twelve months ended September 30, 2023, DSA revenue was $185.1 million compared to $165.3 million for the twelve months ended September 30, 2022, representing an increase of $19.8 million, or 12.0%. The increase in DSA revenue was primarily driven by additional revenue during the twelve months ended September 30, 2023, generated from Integrated Laboratory Systems that was acquired in January 2022, plus new services related to genetic toxicology and pricing increases in general toxicology services. These increases in DSA service revenue were partially offset by decreases in our discovery services revenue, primarily related to the decline in overall biotech funding in the market.

In the fiscal year ended September 30, 2023, we continued to experience study cancellations in our DSA segment due primarily to certain compounds, not yet available for testing, and delayed studies as a result of our clients' re-prioritization of research and development spend and lack of funding. When contracts are terminated, we are generally able to recover, at a minimum, our invested costs. Despite an increased trend in cancellations over the past two years, our flexibility and expanded service offerings have enabled us to eventually replace most of the cancelled or postponed studies with studies from other clients.

DSA operating income decreased by $7.1 million, or 31.8%, driven by an increase in depreciation and amortization expense, an increase in bad debt expense, an increase in start-up costs primarily related to our Rockville facility, an increase in selling expenses in connection with increased revenues and an increase in compensation expense. These increases in DSA operating expenses were partially offset by the increased revenue discussed above. As we built up

capacity during the first three quarters of 2023, operating income was negatively impacted but we had stronger operating income in the fourth quarter.

For the twelve months ended September 30, 2023, RMS revenue was $387.3 million compared to $382.4 million for the twelve months ended September 30, 2022, representing an increase of $4.9 million, or 1.3%. The increase in RMS revenue was due primarily to favorable pricing, particularly for NHPs, partially offset by the negative impact of lower volumes of NHP sales and lower sales of small animal models. Additionally, the increase in RMS revenue was impacted by the timing of contributions from acquisitions. Envigo was acquired on November 5, 2021, RSI was acquired on December 29, 2021, and OBRC was acquired on January 27, 2022.

RMS operating loss was $24.9 million in fiscal year 2023 compared to $189.3 million in fiscal year 2022, a decrease of $164.4 million or 86.8%, primarily driven by a $169.6 million decrease in non-cash goodwill impairment charges. In fiscal year 2022, we recognized a goodwill impairment charge of $236.0 million related to our RMS segment. In the first quarter of fiscal 2023, the Company determined that as a result of the November 16, 2022 event, the uncertainty related to the Company’s ability to import NHPs from Cambodia, and the decrease in its stock price, the carrying value of its goodwill as of December 31, 2022, was required to be quantitatively evaluated. As a result of our impairment assessment for the first quarter in fiscal 2023, we determined that the carrying amount of goodwill attributed to our RMS segment was in excess of its fair value, and therefore we recorded a goodwill impairment loss of $66.4 million within the RMS segment.

The decrease in RMS operating loss due to the increase in revenue and the decrease in the goodwill impairment charge amount was partially offset by a $5.5 million, or 20.8%, increase in operating expenses, which included an increase in selling expenses, primarily due to increased revenue, higher compensation expense and higher legal fees.

Table of Contents

Unallocated corporate costs consist of selling, general and administrative and other operating expenses that are not directly related or allocated to the reportable segments. The decrease in unallocated corporate costs to $71.8 million in fiscal 2023, compared to $96.4 million in fiscal 2022, was primarily driven by a decrease in stock compensation expense as a result of $23.0 million of post-combination, non-cash stock compensation expense relating to the adoption of the Envigo Equity Plan in fiscal 2022 and a decrease in acquisition expenses as a result of the timing of acquisition activity year-over-year. These decreases in unallocated corporate expenses were partially offset by an increase in compensation and benefits and legal and third party fees.

Other Expense

Other expense decreased by $46.2 million for fiscal year 2023 compared to fiscal year 2022. The decrease was primarily due to the loss of $56.7 million in fiscal year 2022 of fair value remeasurement of the embedded derivative component of the convertible notes issued in September 2021, which did not recur in fiscal 2023. For additional information, see “Capital Resources – Convertible Senior Notes” below. There was also an increase in interest expense of $13.3 million in fiscal year 2023 compared to fiscal year 2022, primarily due to the increased debt balance from the draw of our delayed draw term loan in October 2022 and an increase in interest rates year-over-year.

Income Taxes

Our effective income tax rates for fiscal 2023 and fiscal 2022 were 15.6% and 4.3%, respectively. The benefit recorded for fiscal 2023 and fiscal 2022 was $19.3 million and $15.2 million, respectively. The benefit from income taxes for fiscal year 2023 primarily related to deferred tax benefits on the pre-tax loss, partially offset by the impact on tax expense of certain non-deductible permanent book to tax differences related to goodwill impairment, withholding taxes paid in connection with the sale of the Israeli businesses, an increase in valuation allowances and other permanent items. The benefit from income taxes for fiscal year 2022 primarily related to deferred tax benefits on the pre-tax loss, offset primarily by the impact on tax expense of certain non-deductible permanent book to tax differences related to goodwill impairment, loss on fair value remeasurement of the embedded derivative component of the convertible notes, compensation, and other permanent items.

Consolidated Net Loss

As a result of the above described factors, we had a consolidated net loss of $104.9 million for the twelve months ended September 30, 2023, as compared to a consolidated net loss of $337.3 million during the twelve months ended September 30, 2022.

Liquidity and Capital Resources

As of September 30, 2023, the Company had cash and cash equivalents of approximately $35.5 million compared to $18.5 million of cash, cash equivalents and restricted cash as of September 30, 2022, an increase of $17.0 million.

The November 16, 2022 event and our decision to refrain from selling or delivering Cambodian NHPs held in the U.S. at that time triggered a material adverse event clause in our Credit Agreement discussed in Note 7 - Debt to our consolidated financial statements contained in Part II, Item 8, resulting in, among other things, a limitation of our ability to draw on our revolving credit facility. The loss of access to our revolving credit facility and reduced liquidity resulting from the decision to refrain, at that time, from selling Cambodian NHPs held in the U.S. resulted in reduced forecasted liquidity. As a result of these events, we took steps to improve our liquidity, which included negotiating an amendment to our Credit Agreement, which was executed on January 9, 2023, to reinstate our ability to borrow under our revolving credit facility. Without the amendment, we were at risk of not having the revolving credit facility available.

We have taken several additional steps designed to improve our liquidity, including our site optimization strategy which is intended to allow us to reduce overhead and create efficiencies through scale. During the first quarter of fiscal 2023, we completed the closure of our Cumberland and Dublin, Virginia facilities. Also in the first quarter of fiscal 2023, we announced additional site consolidation plans in the U.S. and our intent to consult with employee representatives for a proposed consolidation of certain European and U.K. sites. Prior to the acquisition of Envigo, the Boyertown, Pennsylvania and Haslett, Michigan facilities were identified for relocation of operations to the Denver, Pennsylvania facility. The exits of the Boyertown and Haslett facilities were completed in March 2023. We completed the sale of the Boyertown facility as of September 30, 2023. During fiscal 2023, we completed our consultation with employee representatives at the Gannat, France and Blackthorn, U.K. facilities, and the closures of both facilities were approved. The consolidation of operations at

Table of Contents

Gannat with the operations in Horst, the Netherlands was completed in June 2023, and the consolidation of the operations at the Blackthorn facility with the operations in Hillcrest, U.K. is expected to be complete by the end of March 2024. The RMS St. Louis facility closed in June 2023 and the GEMS operations at the RMS St. Louis facility were relocated to the DSA St. Louis facility and other operational facilities. In July 2023, we made the decision to close our Spain facility and completed the exit of that facility prior to September 30, 2023. Additionally, we completed the sale of our Spain facility in November 2023.

In connection with the site optimizations noted above and other restructuring initiatives, we reduced our workforce. As of September 30, 2023, our headcount was approximately 7% lower than it was as of September 30, 2022,. We also took steps to reduce our 2023 budgeted capital expenditures and certain forecasted expenses, including a reduction of nonessential travel and employee-related expenses among other efficiency-based reductions. Furthermore, we executed RMS price increases that began in January 2023. We also have identified and validated new NHP vendors outside of Cambodian to diversify our suppliers and increase our NHP supply. Additionally, we identified and executed new strategies to improve the efficiency and cost effectiveness of the transportation of our products. In December 2023, the Company announced that it will be partnering with Vanguard Supply Chain Solutions LLC, the Company’s current provider of transportation services, to enable the in-house integration of Inotiv’s North American transportation operations. By taking direct control of its transportation operations, the Company expects to achieve key efficiencies to strengthen internal operations, improve its outgoing supply chain, and bolster service and scientific continuity for clients.

These targeted initiatives implemented by the Company contributed to cash provided by operations of $27.9 million in fiscal 2023 compared to cash used in operations of $5.2 million in fiscal 2022. Cash provided by operating activities in fiscal 2023 also included a decrease in working capital, more specifically a decrease in inventories and prepaid deposits, as well as a decrease in accounts receivable. These decreases in inventories and prepaid expenses were driven by the timing of prepaid deposits for future NHP shipments, the shipment of NHPs and the collection of cash as it relates to the shipments to clients. The decrease in accounts receivable was due to focused collection efforts executed during the fiscal year, as well as timing of invoicing and cash receipts. Partially offsetting these working capital changes were decreases in accounts payable, accrued expenses and other liabilities and fees invoiced in advance.

The Company believes its existing cash and cash equivalents, together with cash generated from operations, will be sufficient to fund its operations, satisfy its obligations, including cash outflows for planned targeted capital expenditures, and comply with minimum liquidity and financial covenant requirements under its debt covenants pursuant to its Credit Agreement for at least the next twelve months. The forecasted operating cash flows include the shipping of the remainder of the Company's existing Cambodian NHP inventory. See Note 7 - Debt to our consolidated financial statements contained in Part II, Item 8 for further information about the Company’s existing credit facilities and requirements under its debt covenants. The Company’s liquidity needs and compliance with covenants depend, among other things, on its ability to source and sell NHPs, its ability to fill its expanded DSA capacity, its ability to generate cash from other operating activities and its ability to manage its forecasted capital expenditures.

Term Loan Facility, DDTL and Incremental Term Loans

Credit Agreement

On November 5, 2021, the Company, certain subsidiaries of the Company (the “Subsidiary Guarantors”), the lenders party thereto, and the Agent, entered into a Credit Agreement (the “Credit Agreement”). The Credit Agreement provides for a term loan facility in the original principal amount of $165.0 million, a delayed draw term loan facility in the original principal amount of $35.0 million (available to be drawn up to 18 months from the date of the Credit Agreement) (the “Initial DDTL” and together with the Additional DDTL, the “DDTL”) and a revolving credit facility in the original principal amount of $15.0 million. On November 5, 2021, the Company borrowed the full amount of the term loan facility, but did not borrow any amounts on the delayed draw term loan facility or the revolving credit facility.

The Company could have elected to borrow on each of the loan facilities at either an adjusted LIBOR rate of interest or an adjusted prime rate of interest. Adjusted LIBOR rate loans accrued interest at an annual rate equal to the LIBOR rate plus a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). The LIBOR rate had to be a minimum of 1.00%. The initial adjusted LIBOR rate of interest was the LIBOR rate plus 6.25%. Adjusted prime rate loans accrue interest at an annual rate equal to the prime rate plus a margin of between 5.00% and 5.50%, depending on the Company’s then current Secured Leverage Ratio. The initial adjusted prime rate of interest was the prime rate plus 5.25%. For the term loan facility, interest expense was accrued at an effective rate of 10.41% and 9.83% for the fiscal years ended September 30, 2023 and 2022, respectively.

The Company must pay (i) a fee based on a percentage per annum equal to 0.50% on the average daily undrawn portion of the commitments in respect of the revolving credit facility and (ii) a fee based on a percentage per annum equal to 1.00% on the average daily undrawn portion of the commitments in respect of the delayed draw loan facility. In each case, such fee shall be paid quarterly in arrears.

Each of the term loan facility and delayed draw term loan facility require annual principal payments in an amount equal to 1.00% of their respective original principal amounts. The Company shall also repay the term loan facility on an annual basis in an amount equal to a percentage of its Excess Cash Flow (as defined in the Credit Agreement), which percentage will be determined by its then current Secured Leverage Ratio. Each of the loan facilities may be repaid at any time. Voluntary prepayments were subject to a 1.00% prepayment premium if made on or prior to November 5, 2023 and other breakage penalties, as defined in the Credit Agreement. Voluntary prepayments made after November 5, 2023 are not subject to any prepayment premium.

The Company is required to maintain a Secured Leverage Ratio of not more than 4.25 to 1.00 for the Company's fiscal quarters through the fiscal quarter ended June 30, 2023, 3.75 to 1.00 beginning with the Company’s fiscal quarter ending September 30, 2023, and 3.00 to 1.00 beginning with the Company’s fiscal quarter ending March 31, 2025. The Company is required to maintain a minimum Fixed Charge Coverage Ratio (as defined in the Credit Agreement), which ratio was 1.00 to 1.00 during the first year of the Credit Agreement and is 1.10 to 1.00 from and after the Credit Agreement’s first anniversary.

Each of the loan facilities is secured by all assets (other than certain excluded assets) of the Company and each of the Subsidiary Guarantors. Repayment of each of the loan facilities is guaranteed by each of the Subsidiary Guarantors.

Utilizing proceeds from the Credit Agreement on November 5, 2021, the Company repaid all indebtedness and terminated the credit agreement related to the First Internet Bank of Indiana (“FIB”) credit facility and recognized a $0.9 million loss on debt extinguishment during the twelve months ended September 30, 2022.

On January 7, 2022, the Company drew $35.0 million on the Initial DDTL. Amounts outstanding under the Initial DDTL accrued interest at an annual rate equal to the LIBOR rate plus a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). The initial adjusted LIBOR rate of

47

interest was the LIBOR rate plus 6.25%. For the Initial DDTL, interest expense was accrued at an effective rate of 10.41% and 9.89% for the fiscal years ended September 30, 2023 and 2022, respectively.

First Amendment to Credit Agreement

On January 27, 2022, the Company, Subsidiary Guarantors, the lenders party thereto, and the Agent entered into the First Amendment to the existing Credit Agreement. The First Amendment provides for, among other things, an increase to the existing term loan facility in the amount of $40.0 million (the “Incremental Term Loans”) and the Additional DDTL in the original principal amount of $35.0 million, which amount is available to be drawn up to 24 months from the date of the First Amendment. The Incremental Term Loans and any amounts borrowed under the Additional DDTL are referred to herein as the “Additional Term Loans”. On January 27, 2022, the Company borrowed the full amount of the Incremental Term Loans, and on October 12, 2022, the Company borrowed the full $35.0 million under the Additional DDTL.

Amounts outstanding under the Additional Term Loans accrued interest at an annual rate equal to the LIBOR rate plus a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). The initial adjusted LIBOR rate of interest was the LIBOR rate plus 6.25%. For the Additional DDTL, interest expense was accrued at an effective rate of 10.57% for the fiscal year ended September 30, 2023.

The Additional Term Loans require annual principal payments in an amount equal to 1.00% of the original principal amount. Voluntary prepayments of the Additional Term Loans were subject to a 1.00% prepayment premium if made on or prior to November 5, 2023 and other breakage penalties, as defined in the Credit Agreement. Voluntary prepayments made after November 5, 2023 are not subject to any prepayment premium.

The Company shall also repay the term loans on an annual basis in an amount equal to a percentage of its Excess Cash Flow (as defined in the Credit Agreement), which percentage will be determined by its then current Secured Leverage Ratio.

The Additional Term Loans are secured by all assets (other than certain excluded assets) of the Company and each of the Subsidiary Guarantors. Repayment of the Additional Term Loans is guaranteed by each of the Subsidiary Guarantors.

The Additional Term Loans will mature on November 5, 2026.

Second Amendment to Credit Agreement

On December 29, 2022, the Company, the Subsidiary Guarantors, the lenders party thereto, and the Agent, entered into a Second Amendment (the “Second Amendment”) to the Credit Agreement.

The Second Amendment provided for, among other things, an extension of the deadline for the Company to provide to the lenders the audited financial statements for the Company’s fiscal year ended September 30, 2022 and an annual budget for 2023; the Company satisfied these requirements by the extended deadline. The Second Amendment added a requirement that the Company provide, within 30 days after the end of each month, an unaudited consolidated balance sheet, statement of income and statement of cash flows as of the end of, and for, such month, as well as a “key performance indicator” report. The Second Amendment also requires that, within 10 business days after the end of each month, the Company will provide a rolling 13-week cash flow forecast prepared on a monthly basis. The Second Amendment further provides that, upon the request of the Required Lenders (as defined in the Credit Agreement), the Company will permit a financial advisor designated by the Required Lenders to meet with management of the Company to discuss the affairs, finances, accounts and condition of the Company during the six-month period following the effective date of the Second Amendment. In addition, the Second Amendment requires the Company to deliver an updated organization chart and certain supplemental information regarding the Company’s subsidiaries in connection with each quarterly report required pursuant to the Credit Agreement.

Under the Second Amendment, the Company could have elected to borrow on each of the loan facilities at either an adjusted term secured overnight financing rate (“Term SOFR”) rate of interest or an alternate base rate of interest. Term SOFR loans accrued interest at an annual rate equal to the applicable Term SOFR rate plus (i) an adjustment percentage equal to between 0.11448% and 0.42826%, depending on the term of the loan (“Adjusted Term SOFR”); provided that, Adjusted Term SOFR could never be less than 1.00%, and (ii) a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). Alternate base rate loans could accrue interest at an annual rate equal to (i) the highest of (a) the Federal Funds Effective Rate (as defined in the Credit

48

Table of Contents

Agreement) plus 0.50%, (b) the Agent’s prime rate and (c) Adjusted Term SOFR for a one-month tenor plus 1.00% (the “Second Amendment Alternate Base Rate”); provided that, the Second Amendment Alternate Base Rate could never be less than 2.00%, plus (ii) a margin of between 5.00% and 5.50%, depending on the Company’s then current Secured Leverage Ratio.

The Second Amendment also provides that the Company may not request any credit extensions under the revolving credit facility under the Credit Agreement, if any of the conditions precedent set forth in Section 4.02 of the Credit Agreement cannot be satisfied, including, without limitation, the making of the representation and warranty that as of the date of the most recent audited financial statements delivered to the Agent, no event, change, circumstance, condition, development or occurrence has had, or would reasonably be expected to result in, either individually or in the aggregate, a Material Adverse Effect (as defined in the Credit Agreement).

In addition, the Second Amendment provided that, no later than January 13, 2023 (or such later date as the Required Lenders shall agree in their discretion), the Company shall (i) appoint a financial advisor on terms reasonably acceptable to the Required Lenders and the Company for a term of at least six months, (ii) provide a 13-week budget to the Agent, and (iii) deliver a perfection certificate supplement updating certain information previously provided with respect to each of the Company and the Subsidiary Guarantors, including information regarding certain collateral and other assets owned by such parties. The Company timely satisfied each of these requirements.

Third Amendment to Credit Agreement

On January 9, 2023, the Company, the Subsidiary Guarantors, the lenders party thereto, and the Agent, entered into a Third Amendment (“Third Amendment”) to the Credit Agreement. The Third Amendment provides that, among other things, during the period beginning on January 9, 2023 and, subject to the terms of the Credit Agreement, ending on the date on which financial statements for the Company’s fiscal quarter ending March 31, 2024 are delivered or are required to be delivered, as long as no event of default has occurred (the “Amendment Relief Period”):

•the Cambodian NHP-related matters, to the extent existing and disclosed to the lenders prior to December 29, 2022, shall not constitute a Material Adverse Effect under the Credit Agreement and will not restrict the Company’s ability to request credit extensions under the revolving credit facility;

•the use of borrowings under the revolving credit facility is limited to funding operational expenses of the Company in the ordinary course and cannot be used for the making or funding of investments, permitted acquisitions or restricted payments, payments or purchases with respect to any indebtedness, bonuses or executive compensation, or judgments, fines or settlements; and

•additional limitations are imposed on the Company under the Credit Agreement, including restrictions on permitted asset sales, a prohibition on making permitted acquisitions, and significant limitations on the ability to incur additional debt, make investments and make restricted payments.

The Third Amendment provides that from and after the date thereof, no incremental facilities under the Credit Agreement may be established or incurred. The Third Amendment also provides for additional mandatory prepayments of borrowed amounts following the receipt by the Company of certain cash receipts, including proceeds from certain equity issuances and cash received by the Company not in the ordinary course of business. Under the Third Amendment, after any draw on the revolving credit facility, the Company’s cash and cash equivalents held on hand domestically within the U.S. cannot exceed $10.0 million.

Under the Third Amendment, the Company may elect to borrow on each of the loan facilities accruing interest at either an adjusted Term SOFR or an alternate base rate of interest. Term SOFR loans shall accrue interest at an annual rate equal to the applicable Term SOFR rate plus (i) an adjustment percentage equal to between 0.11448% and 0.42826%, depending on the term of the loan, provided that, the Adjusted Term SOFR shall never be less than 1.00% per annum, plus (ii) an applicable margin of 6.75% per annum for term loans maintained as SOFR loans or 9.50% per annum for revolving loans maintained as SOFR loans. Alternate base rate loans shall accrue interest at an annual rate equal to (i) the highest of (a) the Federal Funds Effective Rate (as defined in the Credit Agreement) plus 0.50%, (b) the Agent’s prime rate and (c) Adjusted Term SOFR for a one-month tenor plus 1.00% (the “Alternate Base Rate”), provided that, the Alternate Base Rate is subject to a floor of 2.00% per annum plus (ii) an applicable margin of 5.75% per annum for term loans maintained as Alternate Base Rate loans or 8.50% per annum for revolving loans maintained as Alternate Base Rate loans.

The fee consideration payable by the Company for each consenting lender party to the Third Amendment is: (i) 0.50% of the aggregate outstanding principal amount of the term loans held by each consenting term loan lender, to be paid in-kind and capitalized to the principal amounts of the term loans held by such lender; (ii) 0.50% of the aggregate outstanding principal amount of the term loans held by each consenting term loan lender, to be paid in cash upon the occurrence of certain prepayments of the term loan under the Credit Agreement; and (iii) 7.00% of the aggregate amount of the revolving commitments held by each consenting revolving lender, to be paid in cash upon the occurrence with certain permanent reductions of the revolving loans under the Credit Agreement

Acquisition-related Debt (Seller Notes)

In addition to the indebtedness under the Credit Agreement, certain of the Company’s subsidiaries have issued unsecured notes as partial payment of the purchase prices of certain acquisitions as described herein. Each of these notes is subordinated to the indebtedness under the Credit Agreement.

As part of acquisition of Pre-Clinical Research Services, Inc. ("PCRS"), the Company issued an unsecured subordinated promissory note payable to the PCRS seller in the initial principal amount of $0.8 million. The promissory note bears interest at a rate of 4.50% per annum with monthly payments of principal and interest and a maturity date of December 1, 2024.

As part of the acquisition of Bolder BioPATH, the Company issued unsecured subordinated promissory notes payable to the former shareholders of Bolder BioPATH in an aggregate principal amount of $1.5 million. As part of the working capital adjustment in March 2022, a reduction of the promissory note of $0.5 million was recorded. The promissory notes bear interest at a rate of 4.50% per annum, with monthly payments of principal and interest and a maturity date of May 1, 2026.

As part of the acquisition of Plato, the Company issued unsecured subordinated promissory notes payable to the former shareholders of Plato in an aggregate principal amount of $3.0 million. The promissory notes bear interest at a rate of 4.50% per annum, with monthly payments of principal and interest and a maturity date of June 1, 2023. The promissory notes were paid in full as of June 1, 2023.

As part of the acquisition of OBRC, the Company agreed to leave in place a payable owed by OBRC to the Seller in the amount of $3.7 million, which the Company determined to have a fair value of $3.3 million as of January 27, 2022. The payable does not bear interest and was originally required to be paid to the Seller 18 months after the closing date of January 27, 2022. The Company has the right to set off against the payable any amounts that become payable by the Seller on account of indemnification obligations under the purchase agreement. On April 4, 2023, the Company and the Seller entered into a First Amendment to extend the maturity date of the payable to July 27, 2024. This extension did not affect the rights and remedies of any party to the stock purchase agreement, nor alter, modify or amend or in any way affect any of the terms and conditions, obligations, covenants or agreements contained in the stock purchase agreement.

As part of the acquisition of Histion, the Company issued unsecured subordinated promissory notes payable to the former shareholders of Histion in an aggregate principal amount of $0.4 million. The promissory notes bear interest at a rate of 4.50% per annum, with monthly payments of principal and interest and a maturity date of April 1, 2025.

As part of the acquisition of Protypia, the Company issued unsecured subordinated promissory notes payable to the former shareholders of Protypia in an aggregate principal amount of $0.6 million. The promissory notes bear interest at a rate of 4.50% per annum, with monthly interest payments and principal payments on July 7, 2023, and on the maturity date, January 7, 2024.

Convertible Senior Notes

On September 27, 2021, the Company issued $140.0 million principal amount of the Notes. The Notes were issued pursuant to, and are governed by, an indenture, dated as of September 27, 2021, among the Company, the Company’s wholly-owned subsidiary, BAS Evansville, Inc., as guarantor (the “Guarantor”), and U.S. Bank National Association, as trustee (the “Indenture”). Pursuant to the purchase agreement between the Company and the initial purchaser of the Notes, the Company granted the initial purchaser an option to purchase, for settlement within a period of 13 days from, and including, the date the Notes were first issued, up to an additional $15.0 million principal amount of the Notes. The Notes issued on September 27, 2021 included $15.0 million principal amount of the Notes issued pursuant to the full exercise by the initial purchaser of such option. The Company used the net proceeds from the offering of the Notes, together with

50

Table of Contents

borrowings under a new senior secured term loan facility, to fund the cash portion of the purchase price of the Envigo acquisition and related fees and expenses.

The Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s non-guarantor subsidiaries. The Notes are fully and unconditionally guaranteed, on a senior, unsecured basis, by the Guarantor.

The Notes accrue interest at a rate of 3.25% per annum, payable semi-annually in arrears on April 15 and October 15 of each year, beginning on April 15, 2022. The Notes will mature on October 15, 2027, unless earlier repurchased, redeemed or converted. Before April 15, 2027, noteholders have the right to convert their Notes only upon the occurrence of certain events. From and after April 15, 2027, noteholders may convert their Notes at any time at their election until the close of business on the scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, its common shares or a combination of cash and its common shares, at the Company’s election. The initial conversion rate is 21.7162 common shares per $1 principal amount of Notes, which represents an initial conversion price of approximately $46.05 per common share. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.

As of September 30, 2023 and September 30, 2022, there were $4.2 million and $5.1 million, respectively, in unamortized debt issuance costs related to the Notes. For the year ended September 30, 2023, the total interest expense was $11.1 million, including coupon interest expense of $4.5 million, accretion expense of $5.7 million, and the amortization of debt discount and issuance costs of $0.9 million. For the year ended September 30, 2022, the total interest expense was $10.6 million, including coupon interest expense of $4.6 million, accretion expense of $5.2 million, and the amortization of debt discount and issuance costs of $0.8 million.

The Notes are redeemable, in whole and not in part, at the Company’s option at any time on or after October 15, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per common share of the Company exceeds 130.00% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such notice. The redemption price is a cash amount equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, calling the Notes for redemption pursuant to the provisions described in this paragraph will constitute a Make-Whole Fundamental Change, which will result in an increase to the conversion rate in certain circumstances for a specified period of time.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change repurchase date. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s common shares.

The Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the Notes (which, in the case of a default in the payment of interest on the Notes, are subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the failure by the Company or the Guarantor to comply with certain covenants in the Indenture relating to the ability of the Company or the Guarantor to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company or the Guarantor, as applicable, and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company or the Guarantor in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) certain defaults by the Company, the Guarantor or any of their respective subsidiaries with respect to indebtedness for borrowed money of at least $20.0 million; (vi) the rendering of certain judgments against the Company, the Guarantor or any of their respective subsidiaries for the payment of at least $20.0 million, where such judgments are not discharged or stayed within 60 days after the date on which the

51

Table of Contents

right to appeal has expired or on which all rights to appeal have been extinguished; (vii) certain events of bankruptcy, insolvency and reorganization involving the Company, the Guarantor or any of their respective significant subsidiaries; and (viii) the guarantee of the Notes ceases to be in full force and effect (except as permitted by the Indenture) or the Guarantor denies or disaffirms its obligations under its guarantee of the Notes.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company or the Guarantor (and not solely with respect to a significant subsidiary of the Company or the Guarantor) occurs, then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then the trustee, by notice to the Company, or noteholders of at least 25.00% of the aggregate principal amount of Notes then outstanding, by notice to the Company and the trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the Notes.

Inflation

We do not believe that inflation has had a material adverse effect on our business, operations or financial condition.

Critical Accounting Policies and Significant Judgments and Estimates

"Management’s Discussion and Analysis of Financial Condition and Results of Operations" and "Liquidity and Capital Resources" 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.

We believe that the application of our accounting policies, each of which require significant judgments and estimates on the part of management, are the most critical to aid in fully understanding and evaluating our reported financial results. Our significant accounting policies are more fully described in Note 2 – Summary of Significant Accounting Policies to our consolidated financial statements contained in Part II, Item 8 – Financial Statements and Supplementary Data in this Annual Report on Form 10-K.

We believe the following represent our critical accounting policies and estimates used in the preparation of our financial statements:

Revenue Recognition

In accordance with Accounting Standards Codification (“ASC”) 606, the Company disaggregates its revenue from clients into two revenue streams, service revenue and product revenue. At contract inception, the Company assesses the services and/or products promised in the contract with the clients to identify performance obligations in the arrangements. In accordance with ASC 606, the Company determines appropriate revenue recognition by completing the following steps: (i) identifying the contract(s) with a client; (ii) identifying the performance obligations in the contract; (iii) determining the transaction price; (iv) allocating the transaction price to the performance obligations in the contract; and (v) recognizing revenue when or as the Company satisfies a performance obligation.

Service revenue

DSA

The Company enters into contracts with clients to provide drug discovery and development services. The Company also offers archive storage services to its clients. The Company’s fixed fee arrangements may involve nonclinical research

52

Table of Contents

services (e.g., toxicology, pathology, pharmacology), bioanalytical, and pharmaceutical method development and validation, nonclinical research services and the analysis of bioanalytical and pharmaceutical samples. For bioanalytical and pharmaceutical method validation services and nonclinical research services, revenue is recognized over time using the input method based on the ratio of direct costs incurred to total estimated direct costs. For contracts that involve in-life study conduct, method development or the analysis of bioanalytical and pharmaceutical samples, revenue is recognized over time when samples are analyzed or when services are performed. In determining the appropriate amount of revenue to recognize over time, the Company forecasts remaining costs related to the contracts with clients. In order to forecast the remaining costs, the Company reviews the billings compared to original cost estimates, meets with project managers and updates cost estimates in relation to any scope changes requested by the client.

The Company generally bills for services on a milestone basis. These contracts represent a single performance obligation and due to the Company’s right to payment for work performed, revenue is recognized over time. Research services contract fees received upon acceptance are deferred until earned and classified within fees invoiced in advance on the consolidated balance sheets. Unbilled revenues represent revenues earned under contracts in advance of billings and are classified within trade receivables and contract assets on the consolidated balance sheets.

Our service contracts typically establish a fixed fee to be paid for identified services. In most cases, some percentage of the contract costs is paid in advance. While we are performing a contract, clients often adjust the scope of services to be provided based on interim project results. Fees are adjusted accordingly. Generally, our fee-for-service contracts are terminable by the client upon written notice of 30 days or less for a variety of reasons, including the client’s decision to forego a particular study, the failure of product prototypes to satisfy safety requirements, and unexpected or undesired results of product testing. Cancellation or delay of ongoing contracts may result in fluctuations in our and annual results. We are generally able to recover, at minimum, our invested costs plus an appropriate margin when contracts are terminated.

RMS

The Company provides GEMS, which include the performance of contract breeding and other services associated with genetically engineered models, client-owned animal colony care, and health monitoring and diagnostics services related to research models. For contracts that involve creation of a specific type of animal, revenue is recognized over time with each milestone as a separate performance obligation. The Company is due payment for work performed even if subsequent milestones are unable to be met. Contract breeding revenue and client-owned animal colony care revenue are recognized over time and are billed as per diems. Health monitoring revenue and diagnostic services revenue are recognized once the service is performed.

Product revenue

DSA

DSA product revenue includes internally-manufactured scientific instruments for life sciences research and the related software for use by pharmaceutical companies, universities, government research centers and medical research institutions under the Company’s BASi product line. These products can be sold to multiple clients and have alternative uses. Both the transaction sales price and shipping terms are agreed upon in the client order. For these products, all revenue is recognized at a point in time, generally when title of the product and control is transferred to the client based upon shipping terms. These arrangements typically include only one performance obligation.

RMS

Product revenue includes research models, diets and bedding and bioproducts. Research models revenue represents the commercial production and sale of research models. Diets and bedding revenue represents laboratory animal diets, bedding, and enrichment products under the Company’s Teklad product line. Bioproducts revenue represents the sale of serum and plasma, whole blood, tissues, organs and glands, embryo culture serum and growth factors. Product revenue is recognized at the point in time when the Company’s performance obligations with the applicable clients have been satisfied. Revenue is recorded at the transaction price, which is the amount of consideration the Company expects to receive in exchange for transferring products to a client. The performance obligations, including associated freight to deliver products, are met based agreed upon terms, which are generally upon delivery (destination point) and transfer of title. The Company determines the transaction price based on fixed consideration in its contractual agreements. In determining the transaction

53

Table of Contents

price, a significant financing component does not exist since the timing from when the Company delivers product to when the clients pay for the product is less than one year.

Income Taxes

The Company uses the asset and liability approach for financial accounting and reporting of income taxes. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred taxes are measured using rates expected to apply to taxable income in years in which those temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company uses a two-step process for the measurement of uncertain tax positions that have been taken or are expected to be taken in a tax return. The first step is a determination of whether the tax position should be recognized in the consolidated financial statements. The second step determines the measurement of the tax position. The Company records potential interest and penalties on uncertain tax positions as a component of income tax expense.

As of November 5, 2021, with the acquisition of Envigo, the Company adopted an accounting policy regarding the treatment of taxes due on future inclusion of non-U.S. income in U.S. taxable income under the Global Intangible Low-Taxed Income provisions as a current period expense when incurred.

Goodwill and Intangible 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, which represent a significant portion of the purchase price in many of our acquisitions, requires the use of significant judgment with regard to the fair value. We utilize commonly accepted valuation techniques, such as the income, cost and market approaches, as appropriate, in establishing the fair value of intangible assets. Typically, key assumptions include projections of cash flows that arise from identifiable intangible 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. Customer relationship intangible assets are the most significant identifiable definite-lived asset acquired. To determine the fair value of the acquired customer relationships, 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 growth rates, operating income (loss) margins, and customer attrition rates; as well as discount rates based on an analysis of the acquired entities’ weighted average cost of capital.

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, utilizing an assessment date of September 30th, 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. The estimated cash flows used to determine the fair value of the reporting units used in the impairment test requires significant judgment with respect to revenue growth, EBITDA margin, and weighted average cost of capital. 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. See Note 6 - Goodwill and Intangible Assets

to our consolidated financial statements contained in Part II, Item 8 for further discussion related to goodwill impairment charges during the fiscal years ended September 30, 2023 and September 30, 2022.

Definite-lived intangible assets are amortized over the pattern in which the economic benefits of the intangible assets are utilized and qualitatively reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. If quantitative determination of recoverability is required, recoverability of assets to be held and used is determined by the Company at the level for which there are identifiable cash flows by comparison of the carrying amount of the assets to future undiscounted net cash flows utilizing forecasted revenue growth, EBITDA margin, and capital expenditures before interest expense and income taxes expected to be generated by the assets. If the carrying amount exceeds the outcome of the analysis of undiscounted cash flows, impairment is measured through various valuation techniques including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. 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.

The Company amortizes the cost of its intangible assets utilizing the straight-line method over the estimated useful lives of the definite-lived intangible assets as follows:

Asset	Estimated Useful Lives (in years)
Customer relationships	5 - 13
Intellectual property	5 - 20
Other	0 - 15

Long-lived Tangible 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.

Fair Value of Financial Instruments

Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s judgment about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the inputs as follows:

•Level 1 – Valuations based on quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

•Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

•Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

Valuation methodologies used for assets and liabilities measured or disclosed at fair value are disclosed in Note 7 – Debt and Note 9 – Post-Employment Benefits.

Pension Costs

As a result of the Envigo acquisition, the Company has a defined benefit pension plan for one of its U.K. subsidiaries.

The projected benefit obligation and funded position of the defined benefit plan is estimated by actuaries and the Company recognizes the funded status of its defined benefit plan on its consolidated balance sheets and recognizes gains, losses and prior service costs or credits that arise during the period that are not recognized as components of net periodic benefit cost as a component of accumulated other comprehensive income (loss), net of tax. The Company measures plan assets and

obligations as of the date of the Company’s year-end consolidated balance sheet, using assumptions to anticipate future events.

Additional information about certain effects on net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition assets or obligations are disclosed in the notes to the consolidated financial statements (see Note 9 – Post-Employment Benefits).

Our significant accounting policies, including new accounting pronouncements, are described in more detail in Note 2 of the Notes to Consolidated Financial Statements included in response to Item 8 of this Report.

ITEM 7A – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We are exposed to changes in interest rates while conducting normal business operations as a result of ongoing financing activities. As of September 30, 2023, our debt portfolio was reliant on reference rates. Based on our interest rate exposure at September 30, 2023, assumed debt levels throughout the next 12 months, a one-percentage-point increase in interest rates would result in an estimated $2.7 million pre-tax reduction in net earnings over a one-year period.

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 the Company’s foreign subsidiaries are the Euro, British Pound and Israeli Shekel.

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 (loss) 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.

A hypothetical 10% change in the foreign exchange rates applicable to our business would change our cash balance as of September 30, 2023 by approximately $0.3 million and our revenue for the twelve months ended September 30, 2023 by approximately $9.0 million.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Inotiv, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Inotiv, Inc. (the Company) as of September 30, 2023 and 2022, the related consolidated statements of operations, comprehensive (loss) income, shareholders' equity and cash flows for each of the two years in the period ended September 30, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at September 30, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended September 30, 2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of September 30, 2023, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated December 11, 2023 expressed an adverse opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue recognition for Over Time Service Contracts

Description of the matter

For the year ended September 30, 2023, the Company recorded service revenue of $223.8 million. As described in Note 2 to the consolidated financial statements, the Company derives a portion of its revenues from service revenue contracts which include fixed fee arrangements. Certain of these service revenue contracts are recognized over time (“Over Time Service Contracts”) using the input method based on the ratio of direct costs incurred to date under the contract to total estimated direct costs expected to be incurred to complete the contract. Auditing the revenue recognition related to Over Time Service Contracts can be challenging due to the judgment by management in determining the timing of recognition of revenue as services are provided, including the Company’s estimate of expected costs to be incurred to complete the contract. Auditing the estimate of expected costs involved a high degree of auditor judgment and increased audit effort due to the determination of the current status of the contract and remaining cost to complete and their impact on the amount of revenue recognized.

How we addressed the matter in our audit

Our audit procedures relating to management’s estimates included, among others, selecting a sample of contracts and comparing the transaction prices to the consideration expected to be received based on current rights and obligations under the contracts and any contract modifications that were agreed upon with the customers. We tested costs incurred and applied to contracts for accuracy, existence, completeness, and proper classification. We evaluated the reasonableness of management’s forecast of remaining costs for the selected contracts, which included understanding the current status of the contract, comparing current estimated costs to original estimates and corroborating our understanding of the status and remaining cost estimates of projects through discussions with project managers. Lastly, we evaluated the reasonableness of management’s estimate by comparing final contract costs to cost estimates for a sample of historical in-process service contracts completed in the current year.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Inotiv, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Inotiv, Inc.’s internal control over financial reporting as of September 30, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weaknesses described below on the achievement of the objectives of the control criteria, Inotiv, Inc. (the Company) has not maintained effective internal control over financial reporting as of September 30, 2023, based on the COSO criteria.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment. Management has identified material weaknesses related to:

a) Management did not design and maintain effective controls over information technology general controls (ITGCs) for all applications that are relevant to the preparation of the consolidated financial statements throughout the year ended September 30, 2023, which resulted in ineffective business process controls (automated and IT-dependent manual controls) that could result in misstatements potentially impacting all of the financial statement accounts and disclosures; and

b) the Company did not effectively design and implement components of the COSO framework to address all relevant risks of material misstatement, including elements of the control environment, information and communication, control activities and monitoring activities components, relating to: (i) providing sufficient and timely management oversight and ownership over the internal control evaluation process; (ii) hiring and training sufficient personnel to timely support the Company’s internal control objectives; and (iii) performing timely monitoring and oversight to ascertain whether the components of internal control are present and functioning effectively. As a result, controls relevant to all business processes and related controls (including relevant entity level controls) were deemed ineffective at September 30, 2023.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2023 consolidated financial statements of the Company. These material weaknesses were considered in determining the nature, timing and extent of audit tests applied in our audit of the 2023 consolidated financial statements, and this report does not affect our report dated December 11, 2023, which expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s report on internal control over financial reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

61

Table of Contents

generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

INOTIV, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands, except share amounts, unless otherwise indicated)

1.    DESCRIPTION OF THE BUSINESS

Inotiv, Inc. and its subsidiaries (“we,” “our,” “us,” "the Company,” “Inotiv”) began operating in 1975 as Bioanalytical Systems, Inc. Bioanalytical Systems, Inc. was incorporated in 1974 and we completed our initial public offering in 2000. On March 18, 2021, the Company filed Articles of Amendment to the Company’s Second Amended and Restated Articles of Incorporation, as amended, and amended its Second Amended and Restated Bylaws, as amended, to reflect a corporate name change from Bioanalytical Systems, Inc. to Inotiv, Inc. Our stock is traded on the Nasdaq Stock Market LLC under the symbol “NOTV.” We are headquartered in West Lafayette, Indiana. Our headquarters mailing address is 2701 Kent Avenue, West Lafayette, Indiana, 47906, and the telephone number at that location is (765) 463-4527. Our Internet site is www.inotivco.com. The information contained on our website is not a part of this Report and is not incorporated by reference herein.

Operational Update

During the twelve months ended September 30, 2023, our focus for our business within the Research Models and Services ("RMS") segment included navigating the global non-human primate ("NHP") market and executing on our site optimization plans. Our site optimization activities are discussed further in Note 11 - Restructuring and Assets Held for Sale. On November 16, 2022, the Company became aware that the U.S. Attorney’s Office for the Southern District of Florida (“USAO-SDFL”) had criminally charged employees of the principal supplier of NHPs to the Company, along with two Cambodian government officials, with conspiring to illegally import NHPs into the U.S. from December 2017 through January 2022 and in connection with seven specific imports between July 2018 and December 2021 (the "November 16, 2022 event"). The Company has not been directed to refrain from selling the Cambodian NHPs in its possession in the U.S. However, due to the allegations contained in the indictment involving the supplier and the Cambodian government officials, the Company believed that it was prudent, at the time, to refrain from selling or delivering any of its Cambodian NHPs held in the U.S. until the Company’s staff and external experts could evaluate what additionally could be done to satisfy itself that the NHPs in inventory from Cambodia can be reasonably determined to be purpose-bred. Historically, the Company relied on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (“CITES”) documentation and related processes and procedures, including release of each import by U.S. Fish and Wildlife Service. After a thorough review of the documentation we have for the Cambodian NHPs in our inventory and their colonies, we resumed shipping a limited amount of Cambodian NHPs. In addition, we completed audits on site at our Cambodian supplier and we worked to establish even more robust procedures for future imports. We have focused on working with our suppliers and developing a long-term solution to establish procedures we can be comfortable assuring ourselves, and our customers, we only provide purpose bred NHPs from Cambodia. We have scientists inside and outside our organization working towards establishing new testing procedures for importing purpose bred Cambodian NHPs and meeting the needs of drug discovery and development in the U.S. In the meantime, we continued to import from countries outside of Cambodia to satisfy demand at our DSA business segment and to our RMS clients.

The Company believes its existing cash and cash equivalents, together with cash generated from operations, will be sufficient to fund its operations, satisfy its obligations, including cash outflows for planned targeted capital expenditures, and comply with minimum liquidity and financial covenant requirements under its debt covenants pursuant to its Credit Agreement for at least the next twelve months. The forecasted operating cash flows include the shipping of the Company's existing Cambodian NHP inventory. See Note 7 - Debt to our consolidated financial statements for further information about the Company’s existing credit facilities and requirements under its debt covenants. The Company’s liquidity needs and compliance with covenants depend, among other things, on its ability to source and sell NHPs, its ability to fill its expanded DSA capacity, its ability to generate cash from other operating activities and its ability to manage its forecasted capital expenditures.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

69

Table of Contents

The Company consolidates a variable interest entity (“VIE”) as a result of the Envigo acquisition. The VIE does not materially impact our net assets or net (loss) income.

The Company accounts for noncontrolling interests in accordance with Accounting Standards Codification (“ASC”) 810, “Consolidation” (“ASC 810”). ASC 810 requires companies with noncontrolling interests to disclose such interests as a portion of equity but separate from the parent’s equity. The noncontrolling interests’ portion of net income (loss) is presented on the consolidated statements of operations.

Comprehensive loss for the year and period presented is comprised of consolidated net loss plus the change in the cumulative translation adjustment equity account and the adjustments, net of tax, for the current year actuarial gains (losses) and prior service costs in connection with the Company’s defined benefit plan.

Transactions in currencies other than the functional currency of each entity are recorded at the rates of exchange at the date of the transaction. Monetary assets and liabilities in currencies other than the functional currency are translated at the rates of exchange at the balance sheet date and the related transaction gains and losses are reported in the consolidated statements of operations, in operating income (loss). The Company records gains and losses from re-measuring intercompany loans in other income (expense) in the consolidated statement of operations. Translation adjustments are excluded from the determination of net income (loss) and are recorded as a separate component of equity within accumulated other comprehensive loss in the consolidated financial statements. Foreign exchange losses recorded in other income (expense) on the statements of operations for the fiscal years ended September 30, 2023 and 2022 were $1,682 and $1,907, respectively.

Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation, including the presentation of the loss on debt extinguishment in other non-cash operating activities within the Statement of Cash Flows, other assets within Note 8 - Supplemental Balance Sheet Information the presentation of the components of deferred tax assets and liabilities and the presentation of certain line items within the reconciliation of the effective income tax rate within Note 15 - Income Taxes. These reclassifications had no effect on the reported results of operations.

Segment Reporting

The Company reports its results in two reportable segments: Discovery and Safety Assessment ("DSA") and RMS. The Company’s DSA reportable segment includes services required to take a drug through the early development process including discovery services, which are non-regulated services to assist clients with the identification, screening, and selection of a lead compound for drug development, regulated and non-regulated (Good Laboratory Practice ("GLP") and non-GLP) safety assessment services and internally-manufactured scientific instruments for life sciences research and the related software for use by pharmaceutical companies, universities, government research centers and medical research institutions under the Company’s BASi product line. The Company’s RMS reportable segment includes research models, research model services and Teklad diets and bedding, biological products ("bioproducts") and Genetically Engineered Models and Services (“GEMS”). Research models include the commercial production and sale of small research models, the supply of large research models and bioproducts, including serum and plasma, whole blood, tissues, organs and glands, embryo culture serum and growth factors. Research Model Services include GEMS, which includes the performance of contract breeding and other services associated with genetically engineered models, client-owned animal colony care, and health monitoring and diagnostics services related to research models.

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.

Table of Contents

Revenue Recognition

In accordance with Accounting Standards Codification (“ASC”) 606, the Company disaggregates its revenue from clients into two revenue streams, service revenue and product revenue. At contract inception, the Company assesses the services and/or products promised in the contract with the clients to identify performance obligations in the arrangements. In accordance with ASC 606, the Company determines appropriate revenue recognition by completing the following steps: (i) identifying the contract(s) with a client; (ii) identifying the performance obligations in the contract; (iii) determining the transaction price; (iv) allocating the transaction price to the performance obligations in the contract; and (v) recognizing revenue when or as the Company satisfies a performance obligation.

Service revenue

DSA

The Company enters into contracts with clients to provide drug discovery and development services. The Company also offers archive storage services to its clients. The Company’s fixed fee arrangements may involve nonclinical research services (e.g., toxicology, pathology, pharmacology), bioanalytical, and pharmaceutical method development and validation, nonclinical research services and the analysis of bioanalytical and pharmaceutical samples. For bioanalytical and pharmaceutical method validation services and nonclinical research services, revenue is recognized over time using the input method based on the ratio of direct costs incurred to total estimated direct costs. For contracts that involve in-life study conduct, method development or the analysis of bioanalytical and pharmaceutical samples, revenue is recognized over time when samples are analyzed or when services are performed. In determining the appropriate amount of revenue to recognize over time, the Company forecasts remaining costs related to the contracts with clients. In order to forecast the remaining costs, the Company reviews the billings compared to original cost estimates, meets with project managers and updates cost estimates in relation to any scope changes requested by the client.

The Company generally bills for services on a milestone basis. These contracts represent a single performance obligation and due to the Company’s right to payment for work performed, revenue is recognized over time. Research services contract fees received upon acceptance are deferred until earned and classified within fees invoiced in advance on the consolidated balance sheets. Unbilled revenues represent revenues earned under contracts in advance of billings and are classified within trade receivables and contract assets on the consolidated balance sheets.

Our service contracts typically establish a fixed fee to be paid for identified services. In most cases, some percentage of the contract costs is paid in advance. While we are performing a contract, clients often adjust the scope of services to be provided based on interim project results. Fees are adjusted accordingly. Generally, our fee-for-service contracts are terminable by the client upon written notice of 30 days or less for a variety of reasons, including the client’s decision to forego a particular study, the failure of product prototypes to satisfy safety requirements, and unexpected or undesired results of product testing. Cancellation or delay of ongoing contracts may result in fluctuations in our annual results. We are generally able to recover, at a minimum, our invested costs plus an appropriate margin when contracts are terminated.

RMS

The Company provides GEMS, which include the performance of contract breeding and other services associated with genetically engineered models, client-owned animal colony care, and health monitoring and diagnostics services related to research models. For contracts that involve creation of a specific type of animal, revenue is recognized over time with each milestone as a separate performance obligation. The Company is due payment for work performed even if subsequent milestones are unable to be met. Contract breeding revenue and client-owned animal colony care revenue are recognized over time and are billed as per diems. Health monitoring revenue and diagnostic services revenue are recognized once the service is performed.

Product revenue

DSA

DSA product revenue includes internally-manufactured scientific instruments for life sciences research and the related software for use by pharmaceutical companies, universities, government research centers and medical research institutions under the Company’s BASi product line. These products can be sold to multiple clients and have alternative uses. Both the transaction sales price and shipping terms are agreed upon in the client order. For these products, all revenue is recognized

71

Table of Contents

at a point in time, generally when title of the product and control is transferred to the client based upon shipping terms. These arrangements typically include only one performance obligation.

RMS

Product revenue includes research models, diets and bedding and bioproducts. Research models revenue represents the commercial production and sale of research models. Diets and bedding revenue represents laboratory animal diets, bedding, and enrichment products under the Company’s Teklad product line. Bioproducts revenue represents the sale of serum and plasma, whole blood, tissues, organs and glands, embryo culture serum and growth factors. Product revenue is recognized at the point in time when the Company’s performance obligations with the applicable clients have been satisfied. Revenue is recorded at the transaction price, which is the amount of consideration the Company expects to receive in exchange for transferring products to a client. The performance obligations, including associated freight to deliver products, are met based on agreed upon terms, which are generally upon delivery (destination point) and transfer of title. The Company determines the transaction price based on fixed consideration in its contractual agreements. In determining the transaction price, a significant financing component does not exist since the timing from when the Company delivers product to when the clients pay for the product is less than one year.

Cash Equivalents

Cash and cash equivalents include all highly liquid investments with original maturities of three months or less and consist primarily of amounts invested in money market funds and bank deposits.

Restricted Cash

Restricted cash generally consists of amounts held by our creditors.

Trade receivables and contract assets, net of allowances for credit losses

The Company records trade receivables and contract assets, net of an allowance for credit losses. A contract asset is recorded when a right to consideration in exchange for goods or services transferred to a client is conditioned other than upon the passage of time. Trade receivables are recorded separately from contract assets since only the passage of time is required before consideration is due. The allowance for credit losses is determined each fiscal quarter based on the creditworthiness of its clients, historical collection patterns and economic conditions. Amounts deemed to be uncollectible are reserved or written off against the allowance.

Concentration of Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of trade receivables from clients in the biopharmaceutical, contract research, academic, and governmental sectors. The Company believes its exposure to credit risk is minimal, as the majority of the clients are predominantly well established and viable. Additionally, the Company maintains allowances for potential credit losses. The Company's exposure to credit loss in the event that payment is not received for revenue recognized equals the outstanding trade receivables and contract assets less fees invoiced in advance.

During the fiscal year ended September 30, 2023, one client related to the RMS segment accounted for 22.0% of total revenue. During the fiscal year ended September 30, 2022, one client related to the RMS segment accounted for 28.2% of total revenue. During the fiscal year ended September 30, 2023, no vendor accounted for greater than 10.0% of the sum of cost of services and cost of products. During the fiscal year ended September 30, 2022, one vendor related to the RMS segment accounted for 19.7% of the sum of cost of services and cost of products.

Fair Value of Financial Instruments

Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s judgment about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the inputs as follows:

72

Table of Contents

•Level 1 – Valuations based on quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

•Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

•Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

Valuation methodologies used for assets and liabilities measured or disclosed at fair value are disclosed in Note 7 – Debt and Note 9 – Post-Employment Benefits.

Inventories

Inventories consist primarily of research models stock, biomedical products, diets and bedding, and are stated at the lower of cost or net realizable value. Valuation of NHPs is determined utilizing specific identification methodology and all other inventory valuation is determined utilizing standard costs, approximating average costs. The determination of net realizable value is assessed using the selling price of the products. Provisions are recorded to reduce the carrying value of inventory determined to be unsalable.

Property and Equipment

Property 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 may not be recoverable. Leasehold buildings and improvements are depreciated over the lesser of its estimated useful life or remaining lease term. The cost of normal, recurring, or periodic repairs and maintenance activities related to property and equipment is expensed as incurred.

When the Company disposes of property 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.

The Company generally depreciates the cost of its property and equipment using the straight-line method over the estimated useful lives of the respective assets as follows:

Asset	Estimated Useful Lives
Land	Indefinite
Land improvements	5 - 20
Buildings and building improvements	10 - 40
Machinery and equipment	7 - 10
Furniture and fixtures	7 - 10
Computer hardware and software	3 - 5
Vehicles	3 - 5

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 acquired, liabilities assumed and noncontrolling interests based on their fair values at the dates of acquisition, including identifiable intangible assets, which typically represents a significant portion of the purchase price.

Goodwill and Intangible 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, which represent a significant portion of the purchase price in many of our acquisitions, requires the use of significant judgment with regard to the fair value. We utilize commonly accepted valuation techniques, such as the income, cost and market approaches, as appropriate, in establishing

73

Table of Contents

the fair value of intangible assets. Typically, key assumptions include projections of cash flows that arise from identifiable intangible 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. Customer relationship intangible assets are the most significant identifiable definite-lived asset acquired. To determine the fair value of the acquired customer relationships, 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 growth rates, operating income (loss) margins, and customer attrition rates; as well as discount rates based on an analysis of the acquired entities’ weighted average cost of capital.

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, utilizing an assessment date of September 30th, 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. The estimated cash flows used to determine the fair value of the reporting units used in the impairment test requires significant judgment with respect to revenue growth, EBITDA margin, and weighted average cost of capital. 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. See Note 6 - Goodwill and Intangible Assets for further discussion related to goodwill impairment charges during the fiscal years ended September 30, 2023 and September 30, 2022.

Definite-lived intangible assets are amortized over the pattern in which the economic benefits of the intangible assets are utilized and qualitatively reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. If quantitative determination of recoverability is required, recoverability of assets to be held and used is determined by the Company at the level for which there are identifiable cash flows by comparison of the carrying amount of the assets to future undiscounted net cash flows utilizing forecasted revenue growth, EBITDA margin, and capital expenditures before interest expense and income taxes expected to be generated by the assets. If the carrying amount exceeds the outcome of the analysis of undiscounted cash flows, impairment is measured through various valuation techniques including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. 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.

The Company amortizes the cost of its intangible assets utilizing the straight-line method over the estimated useful lives of the definite-lived intangible assets as follows:

Asset	Estimated Useful Lives (in years)
Customer relationships	5 - 13
Intellectual property	5 - 20
Other	0 - 15

Long-lived Tangible 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.

74

Table of Contents

Leases

At the commencement 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 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 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, manufacturing and production facilities and office space (real estate) and vehicles 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 vehicle leases. The Company’s policy is to not record operating 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.

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. These adjustments are treated as variable lease payments and recognized in the period in which the obligation for these payments was incurred. 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.

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 all relevant factors, including company-specific plans and economic outlook.

Lease income is considered contra-expense within operating expenses.

Pension Costs

As a result of the Envigo acquisition, the Company has a defined benefit pension plan for one of its U.K. subsidiaries.

The projected benefit obligation and funded position of the defined benefit plan is estimated by actuaries and the Company recognizes the funded status of its defined benefit plan on its consolidated balance sheets and recognizes gains, losses and prior service costs or credits that arise during the period that are not recognized as components of net periodic benefit cost as a component of accumulated other comprehensive income (loss), net of tax. The Company measures plan assets and obligations as of the date of the Company’s year-end consolidated balance sheet, using assumptions to anticipate future events.

Additional information about certain effects on net periodic benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition assets or obligations are disclosed in the notes to the consolidated financial statements (see Note 9 – Post-Employment Benefits).

Stock-Based Compensation

The Company may grant stock options, restricted stock and restricted stock units (“RSUs”) to employees and to non-employee directors under stock-based compensation plans. Stock-based compensation is recognized as an expense in the consolidated statements of operations based on the grant date fair value, adjusted for forfeitures when they occur, over the requisite service period.

For stock options, restricted stock and RSUs that vest based on service periods, the Company uses the straight-line method to allocate compensation expense to reporting periods.

75

Table of Contents

The fair value of stock options granted is calculated using the Black-Scholes option-pricing model. Our assumptions are based on historical information and professional judgment is required to determine if historical trends may be indicators of future outcomes. We estimated the following key assumptions for the binomial valuation calculation:

•Risk-free interest rate: The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant for the expected term of the option.

•Expected volatility: The Company uses our historical share price volatility on our common shares for our expected volatility assumption.

•Expected term: The expected term represents the weighted-average period the stock options are expected to remain outstanding. The expected term is determined based on historical exercise behavior, post-vesting termination patterns, options outstanding and future expected exercise behavior.

•Expected dividends: The Company assumes that we will pay no dividends.

Fees Invoiced in Advance

Fees invoiced in advance are considered to be contract liabilities. A contract liability is recorded when consideration is received, or such consideration is unconditionally due, from a client prior to transferring goods or services to the client under the terms of a contract. Contract liabilities are recognized as revenue after control of the products or services is transferred to the client and all revenue recognition criteria have been met.

Fees invoiced in advance includes payments received in advance of the incurrence of cost toward a contract with a client and client prepayments, which are typically used to secure supply of certain animal models and to provide early payment for data or safety assessment services until earned and classified within fees invoiced in advance on the consolidated balance sheets. The fees invoiced in advance are typically credited against sales invoices when products are sold or as services are completed.

Income Taxes

The Company uses the asset and liability approach for financial accounting and reporting of income taxes. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred taxes are measured using rates expected to apply to taxable income in years in which those temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes deferred tax assets to the extent that it believes that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company uses a two-step process for the measurement of uncertain tax positions that have been taken or are expected to be taken in a tax return. The first step is a determination of whether the tax position should be recognized in the consolidated financial statements. The second step determines the measurement of the tax position. The Company records potential interest and penalties on uncertain tax positions as a component of income tax expense.

As of November 5, 2021, with the acquisition of Envigo, the Company adopted an accounting policy regarding the treatment of taxes due on future inclusion of non-U.S. income in U.S. taxable income under the Global Intangible Low-Taxed Income provisions as a current period expense when incurred.

New Accounting Pronouncements

In August 2020, the FASB issued Accounting Standards Update (“ASU”) ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). Amendments in this ASU simplify accounting for certain financial instruments with characteristics of

76

Table of Contents

liabilities and equity, including convertible instruments and contracts on an entity's own equity. The amendments remove the separation models for convertible debt instruments with cash conversion features and convertible instruments with beneficial conversion features. Consequently, a convertible debt instrument will be accounted for as a single liability at its amortized cost and convertible preferred stock will be accounted for as a single debt or equity instrument measured at its historical cost as long as no other features require bifurcation and recognition as derivatives.

The amendments also modify the accounting for certain contracts in an entity's own equity that are currently accounted for as derivatives because of specific settlement provisions. Lastly, the earnings per share ("EPS") calculation is being amended to (i) require entities to use the if-converted method for all convertible instruments and include the effect of potential share settlement; (ii) clarify that the average market price for the period should be used in the computation of the diluted EPS denominator; and (iii) require entities to use the weighted-average share count from each quarter when calculating the year-to-date weighted average share count for all potentially dilutive securities. In the first fiscal quarter of 2022, the Company adopted ASU 2020-06). As a result of the approval of the increase in authorized shares on November 4, 2021 (see Note 13 – Equity), the Convertible Senior Notes conversion rights met all equity classification criteria in ASC 815. As a result, the derivative liability was remeasured as of November 4, 2021 and reclassified out of long-term liabilities and into additional paid-in capital.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income taxes (“ASU 2019-12”), to reduce the complexity of accounting for income taxes, including providing a model under which an entity can consider recording a deferred tax asset (“DTA”) in certain situations previously prohibited. The previous guidance in ASC 740-10-25-4 prohibited recognition of a DTA for a subsequent step-up in the tax basis of goodwill that is related to the portion of goodwill from a prior business combination for which a deferred tax liability (“DTL”) was not initially recognized, in most cases. Under the new approach, an entity can consider a list of factors in determining whether the step-up in tax basis is related to the business combination that caused the initial recognition of goodwill or to a separate transaction. The amendments are effective for public business entities for fiscal years beginning after December 15, 2020. The Company’s adoption of this standard in fiscal year 2022 did not have a significant impact on the consolidated financial statements and related disclosures.

3.    BUSINESS COMBINATIONS

The Company accounts for acquisitions in accordance with ASC 805, Business Combinations. The guidance requires consideration given, including contingent consideration, assets acquired, liabilities assumed and non-controlling interests to be valued at their fair market values at the acquisition date. The guidance further provides that: (1) in-process research and development will be recorded at fair value as an indefinite-lived intangible asset; (2) acquisition costs will generally be expensed as incurred; (3) restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and (4) changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense (benefit). ASC 805 requires that any excess of the purchase price over the fair value of assets acquired, including identifiable intangibles and liabilities assumed, be recognized as goodwill.

notes to the former shareholder of Plato in an aggregate principal amount of $3,000. This business is reported as part of the Company’s DSA reportable segment.

The following table summarizes the final determination and allocation of the fair value of assets acquired and liabilities assumed as of the acquisition date:

	October 4, 2021
Assets acquired and liabilities assumed:
Cash	1,027
Trade receivables and contract assets	853
Prepaid expenses and other assets	133
Property and equipment	1,127
Operating lease right-of-use assets, net	2,272
Goodwill	9,279
Intangible assets	4,800
Accounts payable	(113)
Accrued expenses and other liabilities	(343)
Operating lease liabilities	(2,272)
Deferred tax liabilities	(1,457)
	$	15,306

Property and equipment is mostly composed of lab equipment, furniture and fixtures, and computer equipment. The fair value of property and equipment was determined using a combination of cost and market-based methodologies.

Intangible assets primarily relate to customer relationships. The acquired definite-lived intangible assets are being amortized over a weighted-average estimated useful life of approximately eight years on a straight-line basis. The estimated fair values of the identifiable intangible assets were determined using the "income approach," which is a valuation technique that provides the fair value of an asset based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Some of the significant assumptions inherent in the development of these asset valuations include the estimated net cash flows for each year for each asset or product (including revenues and EBITDA), the appropriate discount rate necessary to measure the risk inherent in each future cash flow stream, the life cycle of each asset, the potential regulatory and commercial success risk, and competitive trends impacting the asset and each cash flow stream, as well as other factors.

Goodwill, which is derived from the enhanced scientific expertise, expanded client base and our ability to provide broader service solutions through a comprehensive portfolio, is recorded based on the amount by which the purchase price exceeds the fair value of the net assets acquired and is not deductible for tax purposes. Goodwill from this transaction is allocated to the Company’s DSA reportable segment.

In accordance with ASC 805-740, the Company established a deferred tax liability with an offset to goodwill in connection with the accounting for the opening balance sheet of the Plato acquisition as a result of book-to-tax differences primarily related to the intangible assets.

5.    SEGMENT AND GEOGRAPHIC INFORMATION

As a result of our strategic acquisition of Envigo in November 2021, which added a complementary research model platform, our full spectrum solutions span two segments: DSA and RMS.

Through our DSA segment, we support the discovery, non-clinical and clinical development needs of researchers and clinicians for primarily small molecule drug candidates, but also including biotherapeutics and biomedical devices. Our scientists have the skills in analytical instrumentation development, chemistry, computer software development, histology, pathology, physiology, surgery, analytical chemistry, drug metabolism, pharmacokinetics, and toxicology to make the services and products we provide increasingly valuable to our current and potential clients. Our principal clients are scientists engaged in analytical chemistry, drug safety evaluation, clinical trials, drug metabolism studies, pharmacokinetics and basic research from small start-up biotechnology companies to some of the largest global pharmaceutical companies.

Through our RMS segment, we offer access to a wide range of high-quality small and large research models for basic research and drug discovery and development, as well as specialized models for specific diseases and therapeutic areas. We combine deep animal husbandry expertise and expanded access to scientists across the discovery and preclinical continuum, which reduces nonclinical lead times and provides enhanced project delivery. In conjunction with our DSA segment, we have the ability to run selected nonclinical studies directly on-site at closely located research model facilities and have access to innovative genetically engineered models and services solutions. We have long-standing relationships with our principal clients, which include biopharmaceutical companies, contract research organizations ("CRO"), and academic and government organizations.

The following table provides a rollforward of the Company’s goodwill for the fiscal years ended September 30, 2023 and 2022:

Balance as of October 1, 2021	$	51,927
Acquisitions - DSA1	39,531
Acquisitions - RMS2	302,346
Impairment - RMS	(236,005)
Foreign exchange impact - RMS	26
Balance as of September 30, 20223	$	157,825
Acquisitions - DSA1	2,828
Impairment - RMS	(66,367)
Balance as of September 30, 20233	$	94,286

1Goodwill for DSA acquisitions relates to the acquisitions in fiscal 2022 and measurement period adjustments during fiscal 2023 related to the fiscal 2022 acquisitions, as disclosed in Note 3 - Business Combinations

2Goodwill for RMS acquisitions relates to the fiscal 2022 acquisitions, as disclosed in Note 3 - Business Combinations.

3The accumulated impairment loss for the RMS segment was $302,220 at September 30, 2023 and $235,853 at September 30, 2022..

Fiscal Year 2023

The increase in goodwill during fiscal year 2023 related primarily to measurement period adjustments in the DSA segment from the acquisition of Protypia, partially offset by goodwill impairment related to the RMS reporting unit (which is reported within the RMS segment).

On November 16, 2022, the Company became aware that the U.S. Attorney’s Office for the Southern District of Florida (“USAO-SDFL”) had criminally charged employees of the principal supplier of non-human primates (“NHPs”) to the Company, along with two Cambodian government officials, with conspiring to illegally import NHPs into the U.S. from December 2017 through January 2022 and in connection with seven specific imports between July 2018 and December 2021 (the “November 16, 2022 event”). During December 2022, the Company determined that as a result of the November 16, 2022 event, which led to the Company’s decision to refrain from selling or delivering any of its Cambodian NHPs held in the U.S. at that time, the uncertainty related to the Company’s ability to import NHPs from Cambodia and the decrease in its stock price, the carrying value of goodwill as of December 31, 2022, was required to be quantitatively evaluated. The carrying value of the Company’s goodwill by reporting unit was determined utilizing the income approach. Based on the Company’s quantitative goodwill impairment test, the fair value of the RMS reporting unit was less than the RMS reporting unit’s carrying value. As a result, a goodwill impairment loss of $66,367 was recorded within the RMS segment.

Fiscal Year 2022

The increase in goodwill during fiscal year 2022 primarily related to the acquisitions of Plato, ILS, Histion and Protypia in the DSA reporting unit and Envigo, RSI and OBRC in the RMS reporting unit, offset by goodwill impairment related to the RMS reporting unit. See Note 3 - Business Combinations for further discussion of these business combinations.

As a part of the annual goodwill assessment, the Company first assessed qualitative factors to determine whether it was necessary to perform the quantitative impairment test. As a result of the qualitative analysis, the Company determined that as a result of the sustained reduction in our stock price during the fiscal year ended September 30, 2022, the carrying value of our goodwill as of fiscal year end must be quantitatively evaluated. The carrying value of the Company’s goodwill by reporting unit was determined utilizing the income approach. Based on the Company’s quantitative goodwill impairment test, which was performed in the fourth quarter of fiscal year 2022, the fair value of the RMS reporting unit was less than the RMS reporting unit’s carrying value. As a result, goodwill impairment losses of $236,005 were recorded.

Fair Value

As of September 30, 2023 and 2022, the fair value of the Company’s term loan facility, DDTL and incremental term loans was $251,200 and $200,460, respectively, based on market pricing. As the fair value is based on significant other observable inputs, it is deemed to be Level 2 within the fair value hierarchy.

As of September 30, 2023 and 2022, the fair value of the Convertible Senior Notes was $70,000 and $111,825, respectively, based on market pricing. As the fair value is based on significant other observable inputs, it is deemed to be Level 2 within the fair value hierarchy.

The book values of the Seller Notes and Seller Payable, which are fixed rate loans carried at amortized cost, approximate the fair value based on current market pricing of similar debt. As the fair value is based on significant other observable outputs, it is deemed to be Level 2 within the fair value hierarchy.

Until November 4, 2021, the embedded derivative conversion feature of the 3.25% Convertible Senior Notes due 2027 (the “Notes”) was subject to fair value measurement on a recurring basis as they included unobservable and significant inputs in determining the fair value. The Company utilized a single factor trinomial lattice model to determine the related fair value of the embedded derivative convertible feature of the Notes at November 4, 2021, and the inputs used included a volatility 40.00%, a bond yield assumption of 10.44% and a remaining maturity period of 5.95 years.

Term Loan Facility, DDTL and Incremental Term Loans

Credit Agreement

On November 5, 2021, the Company, certain subsidiaries of the Company (the “Subsidiary Guarantors”), the lenders party thereto, and the Agent, entered into a Credit Agreement (the “Credit Agreement”). The Credit Agreement provides for a term loan facility in the original principal amount of $165,000, a delayed draw term loan facility in the original principal amount of $35,000 (available to be drawn up to 18 months from the date of the Credit Agreement) (the “Initial DDTL” and together with the Additional DDTL, the “DDTL”) and a revolving credit facility in the original principal amount of $15,000. On November 5, 2021, the Company borrowed the full amount of the term loan facility, but did not borrow any amounts on the delayed draw term loan facility or the revolving credit facility.

The Company could have elected to borrow on each of the loan facilities at either an adjusted LIBOR rate of interest or an adjusted prime rate of interest. Adjusted LIBOR rate loans accrued interest at an annual rate equal to the LIBOR rate plus a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). The LIBOR rate had to be a minimum of 1.00%. The initial adjusted LIBOR rate of interest was the LIBOR rate plus 6.25%. Adjusted prime rate loans accrue interest at an annual rate equal to the prime rate plus a margin of between 5.00% and 5.50%, depending on the Company’s then current Secured Leverage Ratio. The initial adjusted prime rate of interest was the prime rate plus 5.25%. For the term loan facility, interest expense was accrued at an effective rate of 10.41% and 9.83% for the fiscal years ended September 30, 2023 and 2022, respectively.

The Company must pay (i) a fee based on a percentage per annum equal to 0.50% on the average daily undrawn portion of the commitments in respect of the revolving credit facility and (ii) a fee based on a percentage per annum equal to 1.00% on the average daily undrawn portion of the commitments in respect of the delayed draw loan facility. In each case, such fee shall be paid quarterly in arrears.

Each of the term loan facility and delayed draw term loan facility require annual principal payments in an amount equal to 1.00% of their respective original principal amounts. The Company shall also repay the term loan facility on an annual basis in an amount equal to a percentage of its Excess Cash Flow (as defined in the Credit Agreement), which percentage will be determined by its then current Secured Leverage Ratio. Each of the loan facilities may be repaid at any time. Voluntary prepayments were subject to a 1.00% prepayment premium if made on or prior to November 5, 2023 and other breakage penalties, as defined in the Credit Agreement. Voluntary prepayments made after November 5, 2023 are not subject to any prepayment premium.

The Company is required to maintain a Secured Leverage Ratio of not more than 4.25 to 1.00 for the Company's fiscal quarters through the fiscal quarter ended June 30, 2023, 3.75 to 1.00 beginning with the Company’s fiscal quarter ending September 30, 2023, and 3.00 to 1.00 beginning with the Company’s fiscal quarter ending March 31, 2025. The Company is required to maintain a minimum Fixed Charge Coverage Ratio (as defined in the Credit Agreement), which ratio was 1.00 to 1.00 during the first year of the Credit Agreement and is 1.10 to 1.00 from and after the Credit Agreement’s first anniversary.

Each of the loan facilities is secured by all assets (other than certain excluded assets) of the Company and each of the Subsidiary Guarantors. Repayment of each of the loan facilities is guaranteed by each of the Subsidiary Guarantors.

Utilizing proceeds from the Credit Agreement on November 5, 2021, the Company repaid all indebtedness and terminated the credit agreement related to the First Internet Bank of Indiana (“FIB”) credit facility and recognized an $877 loss on debt extinguishment during the twelve months ended September 30, 2022.

On January 7, 2022, the Company drew $35,000 on the Initial DDTL. Amounts outstanding under the Initial DDTL accrued interest at an annual rate equal to the LIBOR rate plus a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). The initial adjusted LIBOR rate of interest was the LIBOR rate plus 6.25%. For the Initial DDTL, interest expense was accrued at an effective rate of 10.41% and 9.89% for the fiscal years ended September 30, 2023 and 2022, respectively.

First Amendment to Credit Agreement

On January 27, 2022, the Company, Subsidiary Guarantors, the lenders party thereto, and the Agent entered into the First Amendment to the existing Credit Agreement. The First Amendment provides for, among other things, an increase to the existing term loan facility in the amount of $40,000 (the “Incremental Term Loans”) and the Additional DDTL in the original principal amount of $35,000, which amount is available to be drawn up to 24 months from the date of the First Amendment. The Incremental Term Loans and any amounts borrowed under the Additional DDTL are referred to herein as the “Additional Term Loans”. On January 27, 2022, the Company borrowed the full amount of the Incremental Term Loans, and on October 12, 2022, the Company borrowed the full $35,000 under the Additional DDTL.

Amounts outstanding under the Additional Term Loans accrued interest at an annual rate equal to the LIBOR rate plus a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). The initial adjusted LIBOR rate of interest was the LIBOR rate plus 6.25%. For the Additional DDTL, interest expense was accrued at an effective rate of 10.57% for the fiscal year ended September 30, 2023.

The Additional Term Loans require annual principal payments in an amount equal to 1.00% of the original principal amount. Voluntary prepayments of the Additional Term Loans were subject to a 1.00% prepayment premium if made on or prior to November 5, 2023 and other breakage penalties, as defined in the Credit Agreement. Voluntary prepayments made after November 5, 2023 are not subject to any prepayment premium.

The Company shall also repay the term loans on an annual basis in an amount equal to a percentage of its Excess Cash Flow (as defined in the Credit Agreement), which percentage will be determined by its then current Secured Leverage Ratio.

The Additional Term Loans are secured by all assets (other than certain excluded assets) of the Company and each of the Subsidiary Guarantors. Repayment of the Additional Term Loans is guaranteed by each of the Subsidiary Guarantors.

The Additional Term Loans will mature on November 5, 2026.

Second Amendment to Credit Agreement

On December 29, 2022, the Company, the Subsidiary Guarantors, the lenders party thereto, and the Agent, entered into a Second Amendment (the “Second Amendment”) to the Credit Agreement.

The Second Amendment provided for, among other things, an extension of the deadline for the Company to provide to the lenders the audited financial statements for the Company’s fiscal year ended September 30, 2022 and an annual budget for 2023; the Company satisfied these requirements by the extended deadline. The Second Amendment added a requirement that the Company provide, within 30 days after the end of each month, an unaudited consolidated balance sheet, statement of income and statement of cash flows as of the end of, and for, such month, as well as a “key performance indicator” report. The Second Amendment also requires that, within 10 business days after the end of each month, the Company will provide a rolling 13-week cash flow forecast prepared on a monthly basis. The Second Amendment further provides that, upon the request of the Required Lenders (as defined in the Credit Agreement), the Company will permit a financial advisor designated by the Required Lenders to meet with management of the Company to discuss the affairs, finances, accounts and condition of the Company during the six-month period following the effective date of the Second Amendment. In addition, the Second Amendment requires the Company to deliver an updated organization chart and certain supplemental information regarding the Company’s subsidiaries in connection with each quarterly report required pursuant to the Credit Agreement.

Under the Second Amendment, the Company could have elected to borrow on each of the loan facilities at either an adjusted term secured overnight financing rate (“Term SOFR”) rate of interest or an alternate base rate of interest. Term SOFR loans accrued interest at an annual rate equal to the applicable Term SOFR rate plus (i) an adjustment percentage equal to between 0.11448% and 0.42826%, depending on the term of the loan (“Adjusted Term SOFR”); provided that,

92

Table of Contents

Adjusted Term SOFR could never be less than 1.00%, and (ii) a margin of between 6.00% and 6.50%, depending on the Company’s then current Secured Leverage Ratio (as defined in the Credit Agreement). Alternate base rate loans could accrue interest at an annual rate equal to (i) the highest of (a) the Federal Funds Effective Rate (as defined in the Credit Agreement) plus 0.50%, (b) the Agent’s prime rate and (c) Adjusted Term SOFR for a one-month tenor plus 1.00% (the “Second Amendment Alternate Base Rate”); provided that, the Second Amendment Alternate Base Rate could never be less than 2.00%, plus (ii) a margin of between 5.00% and 5.50%, depending on the Company’s then current Secured Leverage Ratio.

The Second Amendment also provides that the Company may not request any credit extensions under the revolving credit facility under the Credit Agreement, if any of the conditions precedent set forth in Section 4.02 of the Credit Agreement cannot be satisfied, including, without limitation, the making of the representation and warranty that as of the date of the most recent audited financial statements delivered to the Agent, no event, change, circumstance, condition, development or occurrence has had, or would reasonably be expected to result in, either individually or in the aggregate, a Material Adverse Effect (as defined in the Credit Agreement).

In addition, the Second Amendment provided that, no later than January 13, 2023 (or such later date as the Required Lenders shall agree in their discretion), the Company shall (i) appoint a financial advisor on terms reasonably acceptable to the Required Lenders and the Company for a term of at least six months, (ii) provide a 13-week budget to the Agent, and (iii) deliver a perfection certificate supplement updating certain information previously provided with respect to each of the Company and the Subsidiary Guarantors, including information regarding certain collateral and other assets owned by such parties. The Company timely satisfied each of these requirements.

Third Amendment to Credit Agreement

On January 9, 2023, the Company, the Subsidiary Guarantors, the lenders party thereto, and the Agent, entered into a Third Amendment (“Third Amendment”) to the Credit Agreement. The Third Amendment provides that, among other things, during the period beginning on January 9, 2023 and, subject to the terms of the Credit Agreement, ending on the date on which financial statements for the Company’s fiscal quarter ending March 31, 2024 are delivered or are required to be delivered, as long as no event of default has occurred (the “Amendment Relief Period”):

•the Cambodian NHP-related matters, to the extent existing and disclosed to the lenders prior to December 29, 2022, shall not constitute a Material Adverse Effect under the Credit Agreement and will not restrict the Company’s ability to request credit extensions under the revolving credit facility;

•the use of borrowings under the revolving credit facility is limited to funding operational expenses of the Company in the ordinary course and cannot be used for the making or funding of investments, permitted acquisitions or restricted payments, payments or purchases with respect to any indebtedness, bonuses or executive compensation, or judgments, fines or settlements; and

•additional limitations are imposed on the Company under the Credit Agreement, including restrictions on permitted asset sales, a prohibition on making permitted acquisitions, and significant limitations on the ability to incur additional debt, make investments and make restricted payments.

The Third Amendment provides that from and after the date thereof, no incremental facilities under the Credit Agreement may be established or incurred. The Third Amendment also provides for additional mandatory prepayments of borrowed amounts following the receipt by the Company of certain cash receipts, including proceeds from certain equity issuances and cash received by the Company not in the ordinary course of business. Under the Third Amendment, after any draw on the revolving credit facility, the Company’s cash and cash equivalents held on hand domestically within the U.S. cannot exceed $10,000.

Under the Third Amendment, the Company may elect to borrow on each of the loan facilities accruing interest at either an adjusted Term SOFR or an alternate base rate of interest. Term SOFR loans shall accrue interest at an annual rate equal to the applicable Term SOFR rate plus (i) an adjustment percentage equal to between 0.11448% and 0.42826%, depending on the term of the loan, provided that, the Adjusted Term SOFR shall never be less than 1.00% per annum, plus (ii) an applicable margin of 6.75% per annum for term loans maintained as SOFR loans or 9.50% per annum for revolving loans maintained as SOFR loans. Alternate base rate loans shall accrue interest at an annual rate equal to (i) the highest of (a) the Federal Funds Effective Rate (as defined in the Credit Agreement) plus 0.50%, (b) the Agent’s prime rate and (c) Adjusted Term SOFR for a one-month tenor plus 1.00% (the “Alternate Base Rate”), provided that, the Alternate Base Rate is

The fee consideration payable by the Company for each consenting lender party to the Third Amendment is: (i) 0.50% of the aggregate outstanding principal amount of the term loans held by each consenting term loan lender, to be paid in-kind and capitalized to the principal amounts of the term loans held by such lender; (ii) 0.50% of the aggregate outstanding principal amount of the term loans held by each consenting term loan lender, to be paid in cash upon the occurrence of certain prepayments of the term loan under the Credit Agreement; and (iii) 7.00% of the aggregate amount of the revolving commitments held by each consenting revolving lender, to be paid in cash upon the occurrence with certain permanent reductions of the revolving loans under the Credit Agreement

Acquisition-related Debt (Seller Notes)

In addition to the indebtedness under the Credit Agreement, certain of the Company’s subsidiaries have issued unsecured notes as partial payment of the purchase prices of certain acquisitions as described herein. Each of these notes is subordinated to the indebtedness under the Credit Agreement.

As part of acquisition of Pre-Clinical Research Services, Inc.

The payable does not bear interest and was originally required to be paid to the Seller 18 months after the closing date of January 27, 2022. The Company has the right to set off against the payable any amounts that become payable by the Seller on account of indemnification obligations under the purchase agreement. On April 4, 2023, the Company and the Seller entered into a First Amendment to extend the maturity date of the payable to July 27, 2024. This extension did not affect the rights and remedies of any party to the stock purchase agreement, nor alter, modify or amend or in any way affect any of the terms and conditions, obligations, covenants or agreements contained in the stock purchase agreement.

As part of the acquisition of Histion, the Company issued unsecured subordinated promissory notes payable to the former shareholders of Histion in an aggregate principal amount of $433.

The promissory notes bear interest at a rate of 4.50% per annum, with monthly interest payments and principal payments on July 7, 2023, and on the maturity date, January 7, 2024.

Convertible Senior Notes

On September 27, 2021, the Company issued $140,000 principal amount of the Notes. The Notes were issued pursuant to, and are governed by, an indenture, dated as of September 27, 2021, among the Company, the Company’s wholly-owned subsidiary, BAS Evansville, Inc., as guarantor (the “Guarantor”), and U.S. Bank National Association, as trustee (the “Indenture”). Pursuant to the purchase agreement between the Company and the initial purchaser of the Notes, the Company granted the initial purchaser an option to purchase, for settlement within a period of 13 days from, and including, the date the Notes were first issued, up to an additional $15,000 principal amount of the Notes. The Notes issued on September 27, 2021 included $15,000 principal amount of the Notes issued pursuant to the full exercise by the initial

94

Table of Contents

purchaser of such option. The Company used the net proceeds from the offering of the Notes, together with borrowings under a new senior secured term loan facility, to fund the cash portion of the purchase price of the Envigo acquisition and related fees and expenses.

The Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s non-guarantor subsidiaries. The Notes are fully and unconditionally guaranteed, on a senior, unsecured basis, by the Guarantor.

The Notes accrue interest at a rate of 3.25% per annum, payable semi-annually in arrears on April 15 and October 15 of each year, beginning on April 15, 2022. The Notes will mature on October 15, 2027, unless earlier repurchased, redeemed or converted. Before April 15, 2027, noteholders have the right to convert their Notes only upon the occurrence of certain events. From and after April 15, 2027, noteholders may convert their Notes at any time at their election until the close of business on the scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, its common shares or a combination of cash and its common shares, at the Company’s election. The initial conversion rate is 21.7162 common shares per $1 principal amount of Notes, which represents an initial conversion price of approximately $46.05 per common share. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.

As of September 30, 2023 and September 30, 2022, there were $4,172 and $5,060, respectively, in unamortized debt issuance costs related to the Notes. For the year ended September 30, 2023, the total interest expense was $11,089, including coupon interest expense of $4,515, accretion expense of $5,686, and the amortization of debt discount and issuance costs of $888. For the year ended September 30, 2022, the total interest expense was $10,624, including coupon interest expense of $4,613, accretion expense of $5,162, and the amortization of debt discount and issuance costs of $849.

The Notes are redeemable, in whole and not in part, at the Company’s option at any time on or after October 15, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per common share of the Company exceeds 130.00% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date the Company sends such notice. The redemption price is a cash amount equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, calling the Notes for redemption pursuant to the provisions described in this paragraph will constitute a Make-Whole Fundamental Change, which will result in an increase to the conversion rate in certain circumstances for a specified period of time.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change repurchase date. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s common shares.

The Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the Notes (which, in the case of a default in the payment of interest on the Notes, are subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the failure by the Company or the Guarantor to comply with certain covenants in the Indenture relating to the ability of the Company or the Guarantor to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company or the Guarantor, as applicable, and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company or the Guarantor in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) certain defaults by the Company, the Guarantor or any of their respective subsidiaries with respect to indebtedness for borrowed money of at least $20,000; (vi) the rendering of certain judgments against the Company, the Guarantor or any of their respective subsidiaries for the payment of at least $20,000, where such judgments are not discharged or stayed within 60 days after the date on which the right to appeal has

Table of Contents

expired or on which all rights to appeal have been extinguished; (vii) certain events of bankruptcy, insolvency and reorganization involving the Company, the Guarantor or any of their respective significant subsidiaries; and (viii) the guarantee of the Notes ceases to be in full force and effect (except as permitted by the Indenture) or the Guarantor denies or disaffirms its obligations under its guarantee of the Notes.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company or the Guarantor (and not solely with respect to a significant subsidiary of the Company or the Guarantor) occurs, then the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then the trustee, by notice to the Company, or noteholders of at least 25.00% of the aggregate principal amount of Notes then outstanding, by notice to the Company and the trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the Notes.

In accordance with ASC 815, at issuance, the Company evaluated the convertible feature of the Notes and determined it was required to be bifurcated as an embedded derivative and did not qualify for equity classification. The convertible feature of the Notes is subject to fair value remeasurement as of each balance sheet date or until it meets equity classification requirements and is valued utilizing Level 3 inputs as described below. The discount resulting from the initial fair value of the embedded derivative will be amortized to interest expense using the effective interest method. Non-cash interest expense during the period primarily related to this discount.

In the first quarter of 2022, the Company adopted Accounting Standards Update (“ASU”) ASU 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). The update simplifies the accounting for convertible debt instruments and convertible preferred shares by reducing the number of accounting models and limiting the number of embedded conversion features separately recognized from the primary contract. As a result of the approval of the increase in authorized shares on November 4, 2021 (see Note 13 – Stockholders Equity and Loss Per Share), the Note conversion rights met all equity classification criteria in ASC 815. As a result, the derivative liability was remeasured as of November 4, 2021 and reclassified out of long-term liabilities and into additional paid-in capital.

Based upon the above, the Company remeasured and reclassified to additional paid-in capital the fair value of the embedded derivative as of November 4, 2021, which resulted in a fair value measurement of $88,576 and a loss on remeasurement included in other income (loss) for the fiscal year ended September 30, 2022of $56,714.

Former Credit Agreement

On October 4, 2021, the Company entered into a Third Amendment to Amended and Restated Credit Agreement (the “FIB Amendment”), which amended the Amended and Restated Credit Agreement between the Company and FIB, as amended (the “FIB Credit Agreement”). Pursuant to the FIB Amendment, FIB consented to the acquisition by the Company of Plato by merger of Plato with a wholly owned subsidiary of the Company and the subsequent merger of the surviving corporation of that merger with another wholly owned subsidiary of the Company. In addition, the FIB Amendment amended the FIB Credit Agreement to (i) add the promissory notes to be issued to former Plato shareholders in the Plato acquisition as permitted indebtedness, which notes were issued by the surviving company, guaranteed by the Company and subordinated in favor of FIB, and (ii) add references to the Plato acquisition to certain provisions of the FIB Credit Agreement relating to subordination agreements, representations and warranties, and certain covenants to permit the Plato acquisition to occur. The FIB Amendment included agreements by the Company to obtain certain landlord waivers within 30 days of the closing of the Plato acquisition and to deliver to FIB signed subordination agreements.

The Company consummated the Envigo acquisition and repaid all of its obligations under the FIB Credit Agreement in November 2021.

Gains Related to Changes in Benefit Obligation

The actuarial gains during the twelve months ended September 30, 2023 were primarily due to increased discount rate assumptions as a result of the continued trend of rising interest rates and updated plan cash commutation factors. The actuarial gains during the twelve months ended September 30, 2022 were due to a significant increase in the discount rate

99

Table of Contents

as a result of rising interest rates in the U.K. The remainder of the changes in both periods were cumulative translation adjustments and reductions in assets as a result of overall deterioration in markets, driven by increasing interest rates.

Assumptions

The major assumptions used in determining the net periodic benefit costs for the fiscal year ended September 30, 2023 and 2022:

	Fiscal Year Ended September 30,		Fiscal Year Ended September 30,
	2023		2022
Discount rate	5.33	%	1.85	%
Expected return on plan assets	4.96	%	4.01	%

Our expected return on plan asset assumption, used to determine benefit obligations, is based on historical long-term rates of return on investments. Many factors, including portfolio allocation, target portfolio allocation and expected expenses, are evaluated during the process of determining the expected return on plan assets.

Discount rates were determined for the defined benefit retirement plan at the measurement date to reflect the yield of a portfolio of high-quality bonds matched against the timing and amounts of projected future benefit payments.

At September 30, 2023, we are increasing our long-term rate of return assumption to 4.85% for pension plan assets. The major assumptions used in determining benefit obligations were as follows:

	Fiscal Year Ended September 30,		Fiscal Year Ended September 30,
	2023		2022
Discount rate	5.67	%	5.33	%
Rate of compensation increases	0.00	%	0.00	%

Pension Plan Assets

The Company maintains target allocation percentages among various asset categories based on an investment policy designed to achieve long-term objectives of return, while mitigating downside risk and considering expected cash flows. The Company’s investment policy is reviewed from time to time to ensure consistency with long-term objectives.

Plan assets distribution was as follows:

	Fiscal Year Ended September 30,		Fiscal Year Ended September 30,
	2023		2022
Cash	3.31	%	24.90	%
Equity securities	2.35		6.20

11.    RESTRUCTURING AND ASSETS HELD FOR SALE

During June 2022, the Company approved and announced a plan to close its facility in Cumberland, Virginia. Further, the Company’s restructuring and site optimization plan includes the following sites, which were identified for relocation of operations: Dublin, Virginia, Gannat, France, Blackthorn, U.K., RMS St. Louis, Missouri, Spain, Boyertown, Pennsylvania, and Haslett, Michigan.

For the fiscal years ended September 30, 2023 and 2022, the Company incurred expenses that qualified as exit and disposal costs under GAAP. For the fiscal year ended September 30, 2023, the costs were immaterial and the Company does not expect further material charges as a result of the closures and planned site consolidations. For the fiscal year ended September 30, 2022, costs included employee severance and other costs related to workforce reductions (“employee-related”) of $2,159 and other exit costs (“other”) of $5,351, which primarily related to inventory write-downs related to the exit of the Cumberland facility and costs to maintain the facilities until each facility had been exited. Exit and disposal costs were charged to other operating expense. During the fiscal year ended September 30, 2022, payments of $764 and $3,276 were made for employee-related and other costs, respectively. The remaining exit and disposal costs in fiscal 2022 were non-cash expenses. As of September 30, 2023 and 2022, the liability balance for exit and disposal costs that qualify as employee-related exit and disposal costs was $585 and $1,395, respectively. As of September 30, 2023, the property and equipment related to the facilities at Haslett, Cumberland, Gannat, Blackthorn and Spain were presented within assets held for sale.

Cumberland and Dublin

During June 2022, the Company approved and announced a plan to close its facility in Cumberland, Virginia (“Cumberland facility”) and to close and relocate its operations in Dublin, Virginia (“Dublin facility”) into its other existing facilities, as a part of the Company’s restructuring and site optimization plan. The Cumberland facility exit was also a part of the settlement, as further described in Note 16 – Contingencies. The Cumberland facility exit was completed in September 2022 and the Dublin facility transition was completed in November 2022. The Company determined that the carrying value exceeded the fair value of the real property at the Cumberland and Dublin facilities less costs to sell. As a result, asset impairment charges of $890 and $1,054 were recorded within the RMS reportable segment during the fiscal years ended September 30, 2023 and 2022, respectively. The real property of the Cumberland facility initially met the criteria for assets held for sale as of March 31, 2023 and continued to meet the criteria for assets held for sale as of September 30, 2023. The operations at both the Cumberland facility and the Dublin facility were within the RMS reporting segment.

Gannat, Blackthorn, Spain and RMS St. Louis

During the fiscal year ended September 30, 2023, the Company completed its consultation with employee representatives at the Gannat and Blackthorn facilities and the closures of both facilities were approved. The consolidation of operations at Gannat with the operations in Horst, the Netherlands was completed in June 2023, and the consolidation of the operations at the Blackthorn facility with the operations in Hillcrest, U.K. is expected to be complete by the end of March 2024. In July 2023, the Company decided to close its Spain facility. The exit of the facility in Spain was completed in September 2023 and was sold subsequent to year-end in November 2023. As of June 30, 2023, the real property of the Gannat and

102

Table of Contents

Blackthorn facilities initially met the criteria for assets held for sale, the real property of the Spain facility initially met the criteria for assets held for sale as of September 30, 2023, and all three facilities continued to meet the criteria for assets held for sale as of September 30, 2023. The RMS St. Louis facility closed in June 2023 and the GEMS operations at the RMS St. Louis facility were relocated to the DSA St. Louis facility and other operational facilities. The operations at the Gannat, Blackthorn, Spain and RMS St. Louis facilities were within the RMS reportable segment.

Boyertown and Haslett

Prior to the acquisition of Envigo, the Boyertown and Haslett facilities were identified for relocation of operations to the Denver, Pennsylvania facility. The exits of the Boyertown and Haslett facilities were completed in March 2023. The Boyertown facility was sold in September 2023. The real property of the Haslett facility initially met the criteria for assets held for sale as of March 31, 2023, and continued to meet the criteria for assets held for sale as of September 30, 2023.

Israel

As of December 31, 2022, the assets and liabilities related to the Israel RMS and Israel CRS businesses (the “Israeli Businesses”) initially met the held for sale criteria and, in August 2023, the Company sold its ownership interest in the Israeli Businesses, which were previously reflected in the RMS reportable segment.

Consideration for the sale consisted of (i) $1,000 in cash, (ii) an excess cash adjustment of $316, (iii) real property valued at $3,700, and (iv) a promissory note receivable in the aggregate amount of $2,453. The promissory note bears interest at a rate of 5.00% per annum, with quarterly payments of interest and principal payments on the first anniversary of the closing date and at maturity on August 29, 2025. The sale includes the Company’s 100.00% ownership in Israel RMS and Israel RMS’s 62.50% ownership interest in Israel CRS. Prior to the sale, the management team owned a 37.50% non-controlling ownership position in Israel CRS. The gain of $1,377 on the sale is presented within other income (expense). The combined (loss) income before taxes of the Israeli Businesses for fiscal years ended September 30, 2023 and 2022, was $62 and $4,245, respectively.

During the fiscal years ended September 30, 2023 and 2022, 0 and 9,573,210 common shares, respectively, were issued in relation to acquisitions. See Note 3 – Business Combinations for further discussion of consideration for each acquisition.

Loss Per Share

The Company computes basic loss per share using the weighted average number of common shares outstanding. The Company computes diluted earnings per share using the if-converted method for preferred shares and convertible debt, if any, and the treasury stock method for stock options and restricted stock units.

Accumulated Other Comprehensive Loss

Within the statement of operations, foreign exchange gains and losses are recognized as a result of translations of non-functional currencies. In relation to the translation into U.S. dollars, except for defined benefit pension costs of the Pension Plan, the assets and liabilities of foreign operations are translated using the current exchange rate. For those operations, changes in exchange rates generally do not affect cash flows; therefore, resulting translation adjustments are made in shareholders' equity rather than in the consolidated statements of operations. The Pension Plan relates to a U.K. subsidiary, which currently records a valuation allowance against its net deferred tax assets.

As a result, income tax effects on the net activity have not been presented related to each component of other comprehensive loss for the fiscal years ended September 30, 2023 and 2022.

14.    STOCK-BASED COMPENSATION

Summary of Equity Plans and Activity

The Company has stock-based compensation plans under which employees and non-employee directors may be granted stock-based awards such as stock options, restricted stock (“RSAs”), and restricted stock units (“RSUs”).

During fiscal years 2023 and 2022, the following were share-based awards made to certain employees and their general terms and conditions are:

•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 3 years; and typically expire 10 years from date of grant or 30 days post-termination. In the case of the options issued in relation to the Envigo acquisition, the options expire 10 years from date of grant or 1 year post-termination.

•RSAs, which are shares granted at no cost on the grant date and typically vest over 2 years. With respect to RSAs, recipients do have voting rights on the stock during the vesting period.

•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 typically vest from 1 to 5 years. With respect to RSUs, recipients do not have voting rights on the stock during the vesting period.

In March 2018, the Company's shareholders approved the amendment and restatement of the 2008 Stock Option Plan in the form of the Amended and Restated 2018 Equity Incentive Plan (as amended, the “Equity Plan”). Since March 2018, the Equity Plan has been amended three times:

(i)in March 2020, the Company's shareholders approved an amendment to increase the number of shares issuable under the Equity Plan by 700,000 shares and to make corresponding changes to the number of shares issuable as incentive options and as RSAs or RSUs;

(ii)in November 2021, the Company's shareholders approved an amendment to the Equity Plan to increase the number of shares available for awards thereunder by 1,500,000 shares and to make certain corresponding changes to the Equity Plan; and

(iii)in March 2022, the Company's shareholders approved an amendment to remove certain limitations on the number of stock options, stock appreciation rights, RSAs and RSUs that could be awarded to an employee participant in any fiscal year.

The Company currently grants equity awards from the Equity Plan. At September 30, 2023, 362,361 shares remained available for grants under the Equity Plan.

The Company recognizes expense for all awards subject to graded vesting using the straight-line attribution method. The Company adjusts stock-based compensation expense for forfeitures in the period that a forfeiture occurs. The Company expenses the estimated fair value of stock options over the vesting periods of the grants.

The following table provides stock-based compensation by the financial statement line item in which it is reflected:

	Fiscal Years Ended September 30,
	2023		2022
General and administrative	$	7,844	$	5,960
Other operating expense	—		23,014
Stock-based compensation, before income taxes	7,844		28,974
Provision for income taxes	(311)		(5,123)
Stock-based compensation, net of income taxes	$	7,533	$	23,851

No stock-based compensation related costs were capitalized in fiscal years 2023 and 2022.

The weighted-average assumptions used to compute the fair value of options granted under the Black-Scholes model for the fiscal years ended September 30, 2023 and 2022 were as follows:

	2023		2022
Risk-free interest rate	4.29	%	1.24	%
Dividend yield	—	%	—	%
Volatility of the expected market price of the Company’s common shares	100.59	%	76.62	%
Expected life of the options (years)	3.57		3.24

The volatility assumption used to determine the fair values of options granted for fiscal years 2023 and 2022 is based on historical stock price activity. Further, the assumptions presented for fiscal years 2023 and 2022 are inclusive of the options issued in relation to the Envigo acquisition. Refer to Note 3 - Business Combinations for further information related to those options.

Significant components of the benefit for income taxes were as follows for the years ended September 30, 2023 and 2022:

	2023		2022

Foreign	(374)		(13)
Income tax benefit	$	(19,340)	$	(15,187)

The effective income tax rate on continuing operations varied from the statutory federal income tax rate as follows:

	Fiscal Years Ended September 30
	2023		2022
Federal statutory income tax rate	21.0	%	21.0	%
Increases (decreases):
State and local income taxes, net of Federal tax benefit, if applicable	3.3	%	2.6	%
Loss on Fair Value Remeasurement of Embedded Derivative	—	%	(2.9)	%
Goodwill	(3.5)	%	(16.4)	%
Impact of foreign operations	(0.3)	%	0.3	%
Sale of Israel	(0.8)	%	—	%
Other	1.1	%	(0.7)	%
Valuation allowance changes	(5.2)	%	0.4	%
Effective income tax rate	15.6	%	4.3	%

U.S. GAAP requires that valuation allowances should be established against deferred tax assets based on consideration of all available evidence, both positive and negative, using a “more likely than not” standard. The Company assesses its deferred income taxes to determine if valuation allowances are required or should be adjusted. This assessment considers, among other matters, the nature, frequency and amount of recent losses, the duration of statutory carryforward periods, and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified.

The Company’s U.S. tax reporting group has a cumulative three-year loss. The valuation allowance related to the Company’s U.S. tax reporting group as of September 30, 2023 and 2022 was $4,618 and $0, respectively, and the valuation allowance related to the Company's non-U.S. entities was $11,757 and $10,354, respectively, as the Company does not believe that certain deferred tax assets will be realized in the foreseeable future. Payments made in fiscal years 2023 and 2022 for income taxes, net of refunds, amounted to $7,146 and $479, respectively.

The Company’s non-U.S. subsidiaries’ cumulative undistributed earnings, projected as of September 30, 2023, are considered to be indefinitely reinvested. Accordingly, no provision for U.S. federal and state income taxes or withholding taxes has been made in the accompanying consolidated financial statements. Further, a determination of the unrecognized deferred tax liability for the amount indefinitely reinvested is not practicable due to the complexities in the tax laws and assumptions we would have to make. As of November 5, 2021, with the acquisition of Envigo, the Company adopted an accounting policy regarding the treatment of taxes due on future inclusion of non-U.S. income in U.S. taxable income under the Global Intangible Low-Taxed Income provisions as a current period expense when incurred. Therefore, no deferred tax related to these provisions has been recorded as of September 30, 2023.

At September 30, 2023, the Company had domestic net operating loss carryforwards for federal tax purposes of $23,927, all of which may be carried forward indefinitely. State and local loss carryforwards totaled approximately $67,591. The majority expire from September 30, 2028 through 2042; however, approximately $21,911 may be carried forward

110

Table of Contents

indefinitely, as they relate to states conforming to the provisions of the Tax Cuts and Jobs Act which allowed for an indefinite carryforward period of losses generated after December 31, 2017. The Company had non-U.S. net operating loss carryforwards of $44,412, which have been fully offset by valuation allowance. These losses may be carried forward indefinitely.

The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not to be sustained upon regulatory examination based on the technical merits of the position. The amount of the benefit for which an exposure exists is measured as the largest amount of benefit determined on a cumulative probability basis that we believe is more likely than not to be realized upon ultimate settlement of the position. As of September 30, 2023, there were no material uncertain tax positions based on any federal or state tax position. In fiscal year 2022, the Company established an uncertain tax position of $1,861 in accordance with ASC 805-740 to directly offset acquired foreign net operating losses of $2,222 within the foreign net deferred tax liability. The position was settled during fiscal year 2023.

The Company is no longer subject to U.S. Federal tax examinations for years before 2018 or state and local for years before 2017, with limited exceptions. For federal purposes, the tax attributes carried forward could be adjusted through the examination process and are subject to examination 3 years from the date of utilization.

16.    CONTINGENCIES

Litigation

Envigo RMS, LLC (“Envigo RMS”) is a defendant in a purported class action and a related action under California’s Private Attorney General Act of 2004 (“PAGA”) brought by Jacob Greenwell, a former non-exempt employee of Envigo RMS, on June 25, 2021 in the Superior Court of California, Alameda County. The complaints allege that Envigo RMS violated certain wage and hour requirements under the California Labor Code. PAGA authorizes private attorneys to bring claims on behalf of the State of California and aggrieved employees for violations of California’s wage and hour laws. The class action complaint seeks certification of a class of similarly situated employees and the award of actual, consequential and incidental losses and damages for the alleged violations. The PAGA complaint seeks civil penalties pursuant to the California Labor Code and attorney’s fees. On June 2, 2023, Envigo RMS and the plaintiff signed a Memorandum of Understanding (“MOU”) that sets forth the parties’ intent to settle these matters for $795 which includes attorneys’ fees. The MOU provides that the parties will negotiate and enter into a definitive settlement agreement, which will be subject to court approval. The MOU contains no admission of liability or wrongdoing by Envigo RMS. The MOU provides that, if the settlement is approved by the court, the settlement amount would be paid in four quarterly installments, with the first one to be funded after the court’s final approval of the settlement, and the following ones in the three subsequent quarters. While the timeline for final court approval is not yet determined, the Company took a reserve equal to the proposed settlement amount, which is included in accrued expenses and other liabilities.

On June 23, 2022, a putative securities class action lawsuit was filed in the United States District Court for the Northern District of Indiana, naming the Company and Robert W. Leasure and Beth A. Taylor as defendants, captioned Grobler v. Inotiv, Inc., et al., Case No. 4:22-cv-00045 (N.D. Ind.). The complaint alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, and Rule 10b-5 promulgated thereunder, based on alleged false and misleading statements and material omissions regarding the Company’s acquisition of Envigo RMS and its regulatory compliance. On September 12, 2022, Oklahoma Police Pension and Retirement System was appointed by the Court as lead plaintiff. Thereafter, on November 14, 2022, the lead plaintiff filed an amended complaint against the same defendants, in addition to John E. Sagartz and Carmen Wilbourn, that asserted the same claims along with a claim under Section 14(a) of the Exchange Act. On November 23, 2022, the lead plaintiff filed a further amended complaint against the aforementioned defendants asserting the same claims as the amended complaint and further alleging that false and misleading statements and material omissions were made concerning the Company’s non-human primate business. The purported class in the operative complaint includes all persons who purchased or otherwise acquired the Company’s common stock between September 21, 2021 and November 16, 2022, and the complaint seeks an unspecified amount of monetary damages, interest, fees and expenses of attorneys and experts, and other relief. On January 27, 2023, the defendants filed a motion to dismiss the amended complaint. That motion has been fully briefed since April 28, 2023, and is currently pending. While the Company cannot predict the outcome of this matter, the Company believes the class action to be without merit and plans to vigorously defend itself. We cannot reasonably estimate the maximum potential exposure or the range of possible loss in excess of amounts accrued for this matter.

On September 9, 2022, a purported shareholder derivative lawsuit was filed in the United States District Court for the Northern District of Indiana, naming Robert W. Leasure, Beth A. Taylor, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Grobler v. Robert W. Leasure, et al., Case No. 4:22-cv-00064 (N.D. Ind.). The derivative action asserts claims for breach of fiduciary duty, abuse of control, gross mismanagement, and waste of corporate assets, as well as violations of

111

Table of Contents

Section 14(a) of the Securities Exchange Act of 1934 arising out of the Company’s acquisition of Envigo and its regulatory compliance. On November 15, 2022, the Court entered an order staying the derivative action pending a resolution of a motion to dismiss in the securities class action.

On January 4, 2023, an additional shareholder derivative lawsuit was filed in the United States District Court for the Northern District of Indiana, naming Robert W. Leasure, Beth A. Taylor, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Burkhart v. Robert W. Leasure, et al., Case No 4:23-cv-00003 (N.D. Ind.). The derivative action asserts claims for breach of fiduciary duty, abuse of control, gross mismanagement, and waste of corporate assets, as well as violations of Section 10(b), 21D and 14(a) of the Securities Exchange Act of 1934 arising out of the Company’s acquisition of Envigo and its regulatory compliance. On May 8, 2023, the Court entered an order staying the derivative action pending a resolution of a motion to dismiss in the securities class action.

On April 20, 2023, an additional shareholder derivative lawsuit was filed in the State of Indiana Tippecanoe County Circuit Court, naming Robert W. Leasure, Beth A. Taylor, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Whitfield v. Gregory C. Davis, et al., Case No. 79C01-2304-PL-000048 (Tippecanoe Circuit Court). The derivative action asserts claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, and waste of corporate assets arising out of the Company’s acquisition of Envigo and its regulatory compliance, and the Company’s non-human primate business. On June 20, 2023, the Court entered an order staying the derivative action pending resolution of a motion to dismiss in the securities class action.

On June 2, 2023, an additional shareholder derivative lawsuit was filed in the Indiana Commercial Court of Marion County, naming Robert W. Leasure, Beth A. Taylor, Carmen Wilbourn, Gregory C. Davis, R. Matthew Neff, Richard A. Johnson, John E. Sagartz, Nigel Brown, and Scott Cragg as defendants, and the Company as a nominal defendant, captioned Castro v. Robert W. Leasure, et al., Case No. 49D01-2306-PL-022213 (Marion Superior Court 1). The derivative action asserts claims for breach of fiduciary duty, unjust enrichment, and waste of corporate assets arising out of the Company’s acquisition of Envigo and its regulatory compliance, and the Company’s NHP business. On August 24, 2023, this derivative action was transferred to the Tippecanoe County Circuit Court and consolidated with the derivative action captioned Whitfield v. Gregory C. Davis, et al., Case No. 79C01-2304-PL-000048 (Tippecanoe Circuit Court). The consolidated action remains stayed pending resolution of a motion to dismiss in the securities class action.

While the Company cannot predict the outcome of these matters, the Company believes the derivative actions to be without merit and plans to vigorously defend itself. We cannot reasonably estimate the maximum potential exposure or the range of possible loss in excess of amounts accrued for any of these matters.

The Company is party to certain other legal actions arising out of the normal course of its business. In management's opinion, none of these actions will have a material effect on the Company's operations, financial condition or liquidity.

Government Investigations and Actions

The Company is subject to and/or involved in various government investigations, inquiries and actions, including those described below. Given their inherent uncertainty, the Company cannot predict the duration or outcome of the pending matters described below. An adverse outcome of any of the following matters could have a material adverse impact on the Company’s operations, financial condition, operating results and cash flows.

During the period from July 2021 through March 2022, Envigo RMS’s Cumberland facility was inspected on several occasions by the U.S. Department of Agriculture (“USDA”). USDA issued inspection reports with findings of non-compliance with certain USDA laws and regulations. Envigo RMS formally appealed certain of the findings, and made multiple remediations and improvements at the Cumberland facility, of which it kept USDA apprised.

On May 18, 2022, the U.S. Department of Justice (“DOJ”), together with federal and state law enforcement agents, executed a search and seizure warrant on the Cumberland facility. The warrant was issued by the U.S. District Court for the Western District of Virginia on May 13, 2022. In 2022, EGSI and Inotiv received grand jury subpoenas and other requests from the U.S. Attorney’s Office for the Western District of Virginia (“USAO-WDVA”) for documents and information related to the companies’ compliance with the Animal Welfare Act (“AWA”), the Clean Water Act (“CWA”), the Virginia State Water Control Law and local pretreatment requirements from January 2017 to present. On July 23, 2023, EGSI and Inotiv received a grand jury subpoena from USAO-WDVA for documents related to the Cumberland facility’s compliance with the Clean Air Act, Virginia Air Pollution Control Laws and Regulations, and local requirements from January 1, 2017 to present. Also on July 23, 2023, Inotiv received a grand jury subpoena from USAO-WDVA for documents and information related to the Company’s Alice, Texas facilities’ compliance with the CWA, the Texas State Water Control Law, and local pretreatment requirements from January 1, 2020 to present. Certain current and former employees have also

112

Table of Contents

received subpoenas for testimony and documents related to these matters. The Company is continuing to cooperate with USAO-WDVA and other involved authorities, and is evaluating the potential to resolve the matter. While an unfavorable outcome is probable, the Company cannot predict whether or when it will be able to resolve the matter or reasonably estimate the range of loss.

As previously disclosed, on May 19, 2022, a civil complaint was filed by DOJ against Envigo RMS in the U.S. District Court for the Western District of Virginia alleging violations of the AWA at the Cumberland facility. On July 15, 2022, the court approved a settlement entered into by Envigo RMS, DOJ and the USDA in this civil case, which also comprised USDA’s administrative claims against Envigo RMS for the Cumberland facility, and the civil and administrative complaints were dismissed with prejudice on September 14, 2022. This matter is now fully resolved.

On June 15, 2021, EGSI, a subsidiary of the Company acquired in the Envigo acquisition, received a grand jury subpoena requested by the U.S. Attorney’s Office for the Southern District of Florida (“USAO-SDFL”) for the production of documents related to the procurement of NHPs from foreign suppliers for the period January 1, 2018 through June 1, 2021. The subpoena relates to an earlier grand jury subpoena requested by the USAO-SDFL and received by EGSI’s predecessor entity, Covance Research Products, in April 2019. Envigo acquired EGSI from Covance, Inc., a subsidiary of Laboratory Corporation of America Holdings, in June 2019. As of the filing date of this report, the Company has not received any additional subpoenas related to this matter.

On January 27, 2022, EGSI acquired OBRC, which owns and operates a primate quarantine and holding facility located near Alice, Texas. In 2019, OBRC received grand jury subpoenas requested by the USAO-SDFL requiring the production of documents and information related to its importation of NHPs into the United States. On June 16, 2021, OBRC received a grand jury subpoena requested by the USAO-SDFL requiring the production of documents related to the procurement of NHPs from foreign suppliers for the period January 1, 2018 through June 1, 2021. The OBRC purchase agreement provides for indemnification of EGSI and its officers, directors and affiliates by the Seller, Orient Bio, Inc., for liabilities resulting from actions, inactions, errors or omissions of Orient Bio, Inc. or OBRC related to any period prior to the closing date. As of the filing date of this report, the Company has not received any additional subpoenas related to this matter.

On November 16, 2022 the Company disclosed that employees of the principal supplier of NHPs to the Company, along with two Cambodian government officials, have been criminally charged by the USAO-SDFL with conspiring to illegally import NHPs into the United States from December 2017 through January 2022 and in connection with seven specific imports between July 2018 and December 2021.

Consistent with Company policy, the Company is cooperating with USAO-SDFL in connection with the matters described herein.

On May 23, 2023, Inotiv received a voluntary request from the U.S. Securities and Exchange Commission (“SEC”) seeking documents and information for the period December 1, 2017 to the present regarding the Company, EGSI, and OBRC’s importation of NHPs from Asia, including information relating to whether their importation practices complied with the U.S. Foreign Corrupt Practices Act. The Company is cooperating with the SEC.

17.    SUBSEQUENT EVENTS

On December 5, 2023, the Company entered into a transition services agreement with Vanguard Supply Chain Solutions ("VSCS"). Inotiv will be partnering with VSCS, one of the Company’s current providers of transportation services, to enable the in-house integration of Inotiv’s North American transportation operations. Through September 30, 2023, the Company included the operating results in our consolidated statement of operations, as VSCS was accounted for as a variable interest entity. The Company is assessing the transition for accounting and tax impacts, which would be included in the quarterly report for quarter ending December 31, 2023.

ITEM 9A – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are controls and other procedures designed to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the SEC, including to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is accumulated and communicated to the Company’s management, including our President and Chief Executive Officer (our principal executive officer) and our Chief Financial Officer and Senior Vice President of Finance (our principal financial officer), or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure ("Management").

Management has evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this report. Based on that evaluation, Management has concluded that our disclosure controls and procedures were not effective as of September 30, 2023 because of the material weaknesses in internal control over financial reporting described below.

Notwithstanding the conclusion by Management that our disclosure controls and procedures as of September 30, 2023 were not effective, and notwithstanding the material weaknesses in our internal control over financial reporting described below, Management believes that the consolidated financial statements and related financial information included in this Annual Report on Form 10-K fairly present in all material respects our financial condition, results of operations and cash flows as of the dates presented, and for the periods ended on such dates, in conformity with U.S. GAAP.

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 Exchange Act). Internal control over financial reporting is a process designed by, or under the supervision of Management and effected by the Company’s board of directors, management and other personnel, 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 and includes those policies and procedures that:

a.Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

b.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

c.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. 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.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting can also be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

As of September 30, 2022, Management excluded several of the Company’s previous acquisitions from its assessment of the effectiveness of internal control over financial reporting as permitted by applicable rules. Management's assessment of the effectiveness of internal control over financial reporting as of September 30, 2023, now includes all previous acquisitions.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of September 30, 2023. In making this assessment, Management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013). Based on that assessment, Management concluded that, as of September 30, 2023, the Company’s internal control over financial reporting was not effective, due to the material weaknesses described below.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis.

As of September 30, 2022, Management identified the following material weaknesses in internal controls, which continued to exist as of September 30, 2023:

a.Management did not design and maintain effective controls over information technology general controls (ITGCs) for all applications that are relevant to the preparation of the consolidated financial statements throughout the year ended September 30, 2022, which resulted in ineffective business process controls (automated and IT-dependent manual controls) that could result in misstatements potentially impacting all of the financial statement accounts and disclosures. Specifically, management did not design and maintain: sufficient user access controls to ensure appropriate segregation of duties and adequately restrict user and privileged access to financial applications, programs and data to appropriate Company personnel; and program change management controls to ensure that information technology (“IT”) program and data changes affecting financial information technology applications and underlying accounting records are authorized, tested, and implemented appropriately. As a result, business process controls (automated and IT-dependent manual controls) that are dependent on the ineffective ITGCs, or that use data produced from systems impacted by the ineffective ITGCs were deemed ineffective at September 30, 2022, and were not remediated and therefore remained ineffective at September 30, 2023; and

b.Management did not have an adequate process in place to design and test the operating effectiveness of internal control over financial reporting in a timely manner or an adequate process in place to monitor and provide oversight over the completion of its assessment of internal control over financial reporting. As such, we determined that management did not effectively design and implement components of the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO framework) to address all relevant risks of material misstatement, including elements of the control environment, information and communication, control activities and monitoring activities components, relating to: (i) providing sufficient and timely management oversight and ownership over the internal control evaluation process; (ii) hiring and training sufficient personnel to timely support the Company’s internal control objectives; and (iii) performing timely monitoring and oversight to ascertain whether the components of internal control are present and functioning effectively. As a result, controls relevant to all business processes and related controls (including relevant entity level controls) were deemed ineffective at September 30, 2022, and were not remediated and therefore remained ineffective at September 30, 2023.

As a result of the material weaknesses described above, the Company’s management has concluded that, as of September 30, 2023, our internal control over financial reporting was ineffective. The material weaknesses did not result in any identified misstatements to our consolidated financial statements, and there were no changes to previously released financial results. The Company’s independent registered public accounting firm that audited the consolidated financial statements included in this Annual Report also audited the effectiveness of our internal control over financial reporting and has issued an adverse report on the effectiveness of the Company’s internal control over financial reporting as of September 30, 2023, as set forth below.

Remediation of the Material Weaknesses in Internal Control Over Financial Reporting

As of the date of this Annual Report on Form 10-K, management has updated the design of several of its controls and modified process designs in an effort to improve our internal control over financial reporting and remediate the control deficiencies that led to the material weaknesses, described above. However, there remain several controls and processes

115

Table of Contents

that management continues to re-assess, including the design of controls and modifying processes to improve our internal control over financial reporting. Management’s remediation efforts have included but are not limited to: (i) hiring additional accounting personnel, (ii) hiring key IT personnel with appropriate technical and internal control-related skillsets, and (iii) implementing an internal team dedicated to oversight of control and process design. Management’s ongoing remediation efforts include: (i) improving consistency in ITGCs supported by standard operating procedures to govern the authorization, testing and approval of changes to IT systems supporting all of the Company’s internal control processes, including the implementation of certain applications to achieve these operating procedures, (ii) enhancing design and implementation of our control environment, including the expansion of formal accounting and IT policies and procedures, (iii) designing, implementing, reviewing, analyzing, and properly documenting our review and approval controls, as it relates to ITGCs, account reconciliations, journal entries and estimates, and (iv) continuing to provide training to personnel related to ensuring the accuracy and completeness of data used in the performance of the internal controls.

The material weaknesses cannot be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control Over Financial Reporting

As of September 30, 2022, management had excluded several of its previous acquisitions from its assessment of internal control over financial reporting; however, management's assessment as of September 30, 2023, as described above, now includes the operations of all previous acquisitions. Except for the remediation efforts related to the material weaknesses in internal control over financial reporting described above, there have been no other changes in our internal control over financial reporting that occurred during the fiscal quarter ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
