With a heritage dating back to 1954, we were formerly a business unit of Eli Lilly and Company (Lilly), becoming an independently incorporated company on September 18, 2018. We finalized our separation from Lilly in March 2019. In August 2020 we acquired Bayer Animal Health, marking the largest acquisition in industry history. This acquisition enabled us to become a more diverse, durable and global company with greater reach and scale while also helping us expand our portfolio, creating a better balance between our pet health and farm animal products and between the United States (U.S.) and international markets.

Our foundation for sustained growth and profitability consists of a three-pronged strategy: Innovation, Portfolio and Productivity. We expect to continue to achieve revenue growth and improved profitability by delivering consistent, high-impact Innovation and prioritizing large market opportunities in major geographies. We consistently innovate to improve the health of animals and to benefit our customers. Our focused strategy prioritizes certain assets, including late-stage potential blockbusters, while maximizing life cycle management and refilling the early-stage pipeline to achieve a consistent flow of innovation. We also continue to optimize our diverse Portfolio to grow, leveraging our deep, established customer relationships and expanding product offerings while continuing to drive geographic and channel expansion to reach more of the world's animals. Further, we continue to focus on our strategic Productivity initiatives to improve earnings and cash flows.

Our future growth depends on both the life cycle management of our existing products, as well as our pipeline of new products. In addition to supporting our existing product portfolio, a key element of our targeted value creation strategy is to drive revenue growth through portfolio development and product innovation. We continue to pursue the development of new chemical and biological molecules, as well as additional registrations and indications for current products. Our approach to developing compelling innovation is a build, buy and partner strategy where we seek to develop new products internally, with partners or through licenses or acquisitions. We also seek to maximize geographic coverage for our new product launches. We believe we are an industry leader in animal health R&D, with a track record of successful product innovation, business development and commercialization.

New product development and regulatory highlights during 2024 and 2025 included the following:

Bovaer: In May 2024, the U.S. Food & Drug Administration (FDA) completed its comprehensive, multi-year review of Bovaer® (3-NOP), a first-in-class methane-reducing feed ingredient for use in lactating dairy cattle. Producers began feeding the product to cattle in the U.S. during the third quarter of 2024.

Zenrelia: We received final FDA approval for Zenrelia, a JAK inhibitor targeting control of pruritus and atopic dermatitis in dogs, in September 2024. We launched Zenrelia in the U.S. shortly after final approval and have also received approval for Zenrelia in Australia, Brazil, Canada, the European Union (EU), Japan and the U.K. Additional reviews are ongoing in other markets.

Credelio Quattro: In October 2024, we received final FDA approval for Credelio Quattro, a monthly chewable tablet for dogs that protects against fleas, ticks, heartworms, roundworms, hookworms and three different species of tapeworms. Credelio Quattro was launched in January 2025, and in December 2025 we also received conditional approval for treatment of the New World screwworm. Regulatory approval was received in February 2026 in Australia and additional submissions have now been made in other key markets, including Canada, the EU, Japan and the U.K.

Experior: In October 2024, we received multiple combination clearance approvals from the FDA for Experior to be used in combination with other farm animal products, allowing for broader use in heifers, which represent nearly 40% of the fed cattle population in the U.S.

AdTab: In April 2025, AdTab, a chewable flea and tick treatment for dogs and cats, was approved and launched in the U.K.

Befrena: In December 2025, we received final approval from the U.S. Department of Agriculture (USDA) for Befrena™, a new anti-IL31 monoclonal antibody injection targeting canine allergic and atopic dermatitis. We anticipate launching Befrena in the second quarter of 2026.

Seasonality

While many of our products are sold consistently throughout the year, we do experience seasonality in our pet health business due to increased demand for certain parasiticide product offerings in the first half of the year. For example, in 2025 approximately 70% and 60% of total annual revenue generated by our higher-margin parasiticide products Seresto and Advantage Family, respectively, occurred during the first half of the year, which is reflective of the flea and tick season in the Northern Hemisphere.

Sales and Marketing

Through our global sales force of over 2,200 sales representatives, our veterinary consultants and our key distributors, we seek to build strong customer relationships and fulfill demand for our products. Our sales representatives visit our customers, including consultants, veterinarians, farm animal producers and resellers, to inform, promote and sell our products and to support customers. Our veterinary consultants are available to provide scientific consulting focused on disease management and herd management, training and education on diverse topics, including responsible product use, and generally have advanced degrees in veterinary medicine, veterinary nutrition or other agriculture-related fields. These direct relationships with customers allow us to better understand their needs and provide us access to customer decision makers. Additionally, our sales representatives and veterinary consultants focus on collaborating with our customers to educate and support them on topics such as local disease awareness and to help them adopt new and more sophisticated animal health solutions, which may include the use of our products. In addition, our sales and marketing organization provides enhanced value by supporting farm animal producers to maximize their yields and reduce their costs. Furthermore, our expertise and data analytics help our customers analyze large amounts of health and production data in order to improve production efficiency and business performance.

Customers

We primarily sell our pet health products to third-party distributors and retailers, as well as directly to veterinarians who typically then sell our products to pet owners. We primarily sell our farm animal products to third-party distributors and directly to a diverse set of farm animal producers, including beef, dairy, pork and poultry operations. Our omnichannel presence allows us to sell into both the veterinary clinic and retail markets, including e-commerce.

Table of Contents

Certain top selling pet health products, including the Advantage Family and Seresto, are offered through these channels. Our largest customer, an affiliate of Cencora, Inc., is a third-party veterinary distributor and represented approximately 12% of our total revenue in 2025. Our second largest customer, which is also a third-party distributor, represented approximately 7% of revenue in 2025. No other customer represented greater than 5% of revenue during 2025.

Research and Development

Our R&D efforts focus on delivering consistent, high-impact innovation. Our R&D team is a project driven organization, with projects executed and led by highly experienced individuals with deep technical knowledge and substantial experience in discovery research, clinical sciences, technological development and regulatory expertise across our pet health and farm animal product categories. We believe this approach allows us to consistently progress our multi-year innovation projects toward regulatory approvals, while ensuring clear visibility to the innovation portfolio composition, progress and value.

Our R&D organization utilizes a fully integrated global network of labs, service centers and development sites supported by a network of third-party partners. We also have a significant international regulatory operation that manages new product submissions and ensures ongoing compliance for our existing commercial portfolio. As of December 31, 2025, we employed over 1,000 employees in our global R&D and Regulatory Affairs organizations. Our global R&D sites are comprised of the following:

R&D Centers of Excellence with a Global ScopeMajor Regional Centers for Key Markets
Kemps Creek, AustraliaSpeke, U.K.Sao Paulo, Brazil
Monheim, Germany (1)Fort Dodge, IowaShanghai, China
Bangalore, IndiaIndianapolis, Indiana (R&D headquarters)
Basel, Switzerland

(1)As part of a global restructuring plan approved by our Board of Directors in December 2025 (the 2025 Restructuring Plan), we anticipate closing our animal study facility, which held a portion of our labs in Monheim, Germany, by the end of 2026.

In addition to supporting our existing product portfolio, new product innovation is a core part of our business strategy. We prioritize our R&D efforts across species, development phases and technology platforms, focusing on products that prevent and treat disease, improve and extend quality of life, improve the type of care received by animals and/or reduce the environmental impact of raising livestock. We seek to concentrate our resources on projects that match our strategy and where we can leverage our broad technical and commercial capabilities. We focus R&D investments on projects that target novel product introductions with new active ingredients, as well as products leveraging known active ingredients in new indications, presentations, combinations and species expansion, applying large and small molecule approaches for both farm animals and pets. Additionally, we have expertise in employing various delivery strategies for products, including in-feed, injectable, oral and topical formulations developed in conjunction with our manufacturing team to assure reliable and consistent product supply that leverages the capabilities within our internal and external manufacturing network.

Portfolio investment decisions and prioritization are influenced by the probability of technical success, economic value, time to market, portfolio fit and balance. Maximizing geographic coverage for new product innovations also remains a high priority. R&D expenses totaled $368 million in 2025, $344 million in 2024 and $327 million in 2023.

Manufacturing and Supply Chain

We have a global manufacturing network of 16 sites comprised of the following:

InternationalU.S.
Barueri, BrazilSanta Clara, MexicoClinton, Indiana
Chengdu, ChinaBanwol, South KoreaTerre Haute, Indiana
Wusi, ChinaChungli, TaiwanFort Dodge, Iowa
Huningue, FranceSpeke, United KingdomElwood, Kansas
Cuxhaven, GermanyKansas City, Kansas (1)
Kiel, GermanyWinslow, Maine

(1)As part of the 2025 Restructuring Plan, we anticipate closing our Kansas City manufacturing facility by the end of 2026.

Our products are manufactured both at the sites listed above that are operated by us and across a network of approximately 140 contract manufacturing organizations (CMOs). Our external manufacturing team centrally governs and provides oversight to our global CMO relationships. We select CMOs based on several factors, including: (1) their ability to reliably supply products or materials that meet our quality standards at an optimized cost; (2) their access to specialty products and technologies; (3) capacity; (4) financial analyses; and (5) local

Column 1Column 2

Table of Contents

presence. Our external manufacturing team seeks to ensure that all CMOs we use adhere to our standards of manufacturing quality.

Our strong quality control and quality assurance programs are managed and coordinated globally and are in place at all internal manufacturing sites and external manufacturing hubs. We also regularly inspect and audit our internal sites and CMO locations. To maintain supply of our products, we use a variety of techniques, including comprehensive quality and planning and inventory management systems. We seek to develop an appropriate inventory strategy to fill market demand until an alternative source of supply can be implemented, in the event a supplier becomes unable to provide the required materials or product. However, various developments have led, and in the future may lead, to interruption or shortages in supply until we establish new sources, implement alternative processes, bring new manufacturing facilities online or pause or discontinue product sales in one or more markets.

Pharmaceutical production processes are complex, highly regulated and can vary widely from product to product. Shifting or adding manufacturing capacity can be a lengthy process requiring significant capital expenditures, process modifications and regulatory approvals. As part of our regular and ongoing assessments of the adequacy and cost-effectiveness of our manufacturing capabilities, we may decide to invest in significant improvements to our existing manufacturing facilities. For example, throughout 2025 we have made significant capital investments in the expansion of our biologics manufacturing facility in Elwood, Kansas, as well as expansion projects at other of our global manufacturing facilities. Conversely, we may determine it appropriate to divest or close a manufacturing facility, such as the divestiture of our Manukau, New Zealand, site during 2025 or the planned closure of our Kansas City, Kansas, site in 2026.

Raw Materials

We purchase raw materials and active pharmaceutical ingredients (API) necessary for the commercial production of our products from a variety of third-party suppliers and CMOs. For key API supporting our highest value brands, we generally maintain dual sources. In some instances, we may obtain certain raw or intermediate materials and API from only a single source; however, we utilize inventory management strategies to enable reliable supply. Our active ingredients for biologics are manufactured primarily in internal facilities, while chemically derived active ingredients are sourced from external partners.

Competition

We face intense competition globally. Competition may vary depending on the particular region, species, product category or individual product. We compete principally on the basis of product quality, price, cost-effectiveness, promotional effectiveness, new product development and product differentiation. Some of our products may compete with other branded or generic products already on the market or that are later developed by competitors. When competitors introduce new products with ease-of-use, therapeutic or cost advantages, our products may become subject to decreased sales and/or price reductions.

Our primary competitors include animal health medicines and vaccines companies such as Zoetis Inc., Boehringer Ingelheim Animal Health GmbH, the animal health division of Boehringer Ingelheim GmbH, and Merck Animal Health, the animal health division of Merck & Co., Inc. We also compete with numerous other producers of animal health products throughout the world, including start-up companies working in the animal health area. In addition, we also face competition globally from manufacturers of generic drugs and producers of nutritional health products.

Intellectual Property

Our technology, brands and other intellectual property are important elements of our business. We rely on patent, trademark, copyright and trade secret laws, as well as regulatory exclusivity periods and non-disclosure agreements to protect our intellectual property rights. Our policy is to vigorously protect, enforce and defend our rights to our intellectual property, and we actively seek to protect our proprietary information, including our trade secrets and proprietary know-how, through a variety of means, including by seeking to require our employees, consultants, advisors and partners to enter into confidentiality agreements and other arrangements upon the commencement of their employment or engagement.

Our product portfolio, including product candidates, has approximately 7,000 patents and applications, filed in over 95 countries, with a concentration in our major markets as well as other markets with strong patent laws and protections. While many of the patents and patent applications in our portfolio are the result of our own work, others have been developed in collaboration with partners, acquired through business transactions or licensed to us by third parties. A subset of our current products or product candidates are covered by patents and patent applications. Additionally, many of our vaccine products are based on proprietary or patented master seeds and formulations.

Patents for individual products expire at different times based on the date of the patent filing (or occasionally, the date of patent grant) and the legal term of patents in the countries where such patents are obtained. Some of our principal products, including certain products within our Advantage Family, Rumensin and Maxiban / Monteban do not have patent protection. Other products are protected by patents that expire over the next several years. Below is a summary of our recent and upcoming key patent expirations:

Column 1Column 2

Table of Contents

•Galliprant is protected by patents in the U.S., Europe, Canada, Japan and other key markets. While patents covering the active ingredient, grapiprant, have expired in most markets, patents covering the physical form of grapiprant remain in force and will expire between 2026 and 2031, depending on jurisdiction. Patent coverage relating to methods of use and formulation will expire in 2035 in most jurisdictions.

•The Seresto formulation patent will expire in the U.S. in September 2027. In Europe, the formulation patents expired in June 2025, although in some countries, including Spain, Italy and the U.K., supplementary protection certificates (SPCs) have been granted that expire in August 2026.

•Patent coverage for Interceptor Plus extends through October 2028 in the U.S.

•The U.S. patent for Experior's active ingredient, lubabegron, expired in April 2025. Coverage for Experior methods of use will expire in 2037 in the U.S. and 2035 in other key markets.

We also seek to file and maintain trademarks around the world based on commercial activities in most of the regions where we have, or desire to have, a business presence for a particular product. We currently maintain more than 13,300 trademark applications and registrations in major regions, primarily identifying products dedicated to the care of livestock and pets.

Regulatory Matters

The sale of animal health products is governed by the laws and regulations specific to each country in which we sell our products. To maintain compliance with these regulatory requirements, we have established processes, systems and dedicated resources with end-to-end involvement from product concept to launch and maintenance in the market. Our regulatory function is our key interface with the relevant authorities and is responsible for applying for and obtaining the necessary registrations and post-approvals, extending them if appropriate (e.g., developing claims in additional species), updating (e.g., changes to shelf-life or manufacturing site) and ongoing monitoring of safety and efficacy through our global pharmacovigilance system. In this way, the regulatory function ensures registrations remain valid and our products can continue to be sold. To effectively do this, our regulatory function actively engages in dialogue with the relevant authorities regarding policies that relate to animal health products. In most of our markets, the relevant authority is separate from those governing human medicinal products.

United States

FDA. The regulatory body that is responsible for the regulation of animal health pharmaceuticals in the U.S. is the Center for Veterinary Medicine (CVM), a division of the FDA. All manufacturers of animal health pharmaceuticals must demonstrate their products to be safe, effective and produced by a consistent method of manufacture as defined under the Federal Food, Drug and Cosmetic Act (FFDCA). The FDA’s basis for approving a new animal drug application is documented in a Freedom of Information Summary. Post-approval monitoring of products is required by law, with reports being provided to the CVM’s Office of Surveillance and Compliance. Reports of product quality defects, adverse events or unexpected results are maintained and submitted in accordance with the law. Additionally, as part of the drug experience report, we are required to submit all new information pertaining to the safety or effectiveness of a product, regardless of the source.

USDA. The regulatory body in the U.S. for veterinary biologicals is the USDA. The Center for Veterinary Biologics within the Animal and Plant Health Inspection Service in the USDA is responsible for the regulation of animal health biologicals, which includes but is not limited to vaccines, bacterins, allergens, certain antibodies, antitoxins, toxoids, immunostimulants, certain cytokines, antigenic or immunizing components of live microorganisms and diagnostic components of natural or synthetic origin, or that are derived from synthesizing or altering various substances or components of substances such as microorganisms, genes or genetic sequences, carbohydrates, proteins, antigens, allergens or antibodies. All manufacturers of animal health biologicals must show their products to be pure, safe, effective and produced by a consistent method of manufacture as defined under the Virus Serum Toxin Act. Post-approval monitoring of products is also required. Reports of product quality defects, adverse events or unexpected results are maintained and submitted in accordance with the agency requirements.

Environmental Protection Agency (EPA). The main regulatory body in the U.S. for veterinary pesticides is the EPA. The EPA’s Office of Pesticide Programs is responsible for the regulation of most pesticide products applied to animals in accordance with a memorandum of understanding between the FDA and the EPA for products that are subject to regulation under both the FFDCA and the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). All manufacturers of animal health pesticides must show their products will not cause unreasonable adverse effects to humans or the environment as stated in the act. Within the U.S., individual state pesticide authorities must also approve pesticide products that have been approved by the EPA before distribution in that state. Post-approval monitoring of products is required, with reports provided to the EPA and some state regulatory agencies.

European Union

The European Medicines Agency (EMA) is a centralized agency of the EU responsible for the scientific evaluation of many of the Veterinary Medicinal Products (VMP) developed by pharmaceutical companies for use in the EU. The agency has a veterinary review section distinct from the medical review section for human products. The Committee

Column 1Column 2
12

Table of Contents

for Veterinary Medicinal Products (CVMP) is responsible for scientific review of the submissions for VMP, including immunological products. If the CVMP concludes that all requirements for quality, safety and efficacy are met and the product benefits outweigh the risks, it issues a positive opinion that is forwarded to the European Commission, which makes the final decision following the European comitology procedure. The centralized marketing authorization is valid in all of the EU and in Northern Ireland. All countries that are not part of the EU but belong to the European Economic Area (EEA), such as Norway, Iceland and Liechtenstein, have been part of the scientific assessment done by the CVMP. These countries issue a national marketing approval in accordance with the European Commission's decision.

If approval is sought for products that either cannot or do not need to follow the centralized procedure, approval can also be achieved by national approval in an EEA country agency. This national authorization can be mutually recognized by other EEA countries/EU member states (Mutual Recognition Procedure). In addition, national and mutual recognition can be done in a combined procedure (Decentralized Procedure). A series of regulations, directives, guidelines, EU Pharmacopeia Monographs and other legislation provide the requirements for approval in the EU. In general, these requirements are similar to those in the U.S., requiring demonstrated evidence of purity, safety, efficacy and consistency of manufacturing processes.

The European Food Safety Authority (EFSA) is the agency of the EU that provides scientific advice and communicates with respect to existing and emerging risks associated with the food chain. Based on EFSA’s mandate, it evaluates applications for feed additives, including coccidiostats, enzymes and several nutritionals for animals.

The European Chemicals Agency (ECHA) is the agency of the EU for the safe use of chemicals. Based on the ECHA’s mandate, it conducts the evaluation of biocides for the EU.

We are also governed by each of the national regulatory bodies in the EU.

United Kingdom

The Veterinary Medicines Directorate (VMD) is the main regulatory body in the U.K. responsible for regulating and controlling veterinary pharmaceuticals. A trade agreement between the U.K. and the EU includes regulatory and customs cooperation mechanisms, as well as provisions supporting open and fair competition. The Northern Ireland protocol, which is part of the trade deal, requires that VMD follow EU rules in Northern Ireland. Laws applying to the rest of the U.K. remain largely aligned.

Brazil

The Ministry of Agriculture, Livestock Production and Supply (MAPA) is the regulatory body in Brazil that is responsible for the regulation and control of pharmaceuticals, biologicals, pesticides and medicinal feed additives for animal use. MAPA’s regulatory activities are conducted through the Secretary of Agricultural Defense and its Livestock Products Inspection Department. In addition, regulatory activities are conducted at a State level through the Superintendencies of Agriculture and Livestock (SFA). These activities include the inspection and licensing of both manufacturing and commercial establishments for veterinary products, as well as the submission, review and approval of pharmaceuticals, biologicals and medicinal feed additives. MAPA is one of the most active regulatory agencies in Latin America, having permanent seats at several international animal health forums, such as Codex Alimentarius, World Organization for Animal Health and Committee of Veterinary Medicines for the Americas.

China

The Ministry of Agriculture and Rural Affairs (MARA) is the regulatory body that is responsible for the regulation and control of pharmaceuticals, biologicals, disinfectants, medicinal feed additives, pesticides and feed/feed additives for animal use. There are three organizations under the MARA that regulate animal health:

•The Institute of Veterinary Drug Control (IVDC) is responsible for the evaluation of new applications, renewals, variations, manufacturers, quality methods and tissue residue methods for pharmaceuticals, biologicals, disinfectants and medicinal feed additives.

•The feed/feed additive office is responsible for the registration and renewal of feed and feed additives.

•The pesticide bureau under MARA, the Institute for the Control of Agrochemicals (ICAMA), is responsible for the registration and renewal of pesticide products.

Rest of World

Country-specific regulatory laws typically have provisions that include requirements for certain labeling, safety, efficacy and manufacturers’ quality control procedures (to assure the consistency of the products), manufacturing site standards, as well as company records and reports. Many other countries’ regulatory agencies either refer to some or all of the requirements of the U.S. or EU and may have additional specific local requirements. Most authorities also consider the standards set by international animal health entities, including the World Organization for Animal Health (WOAH), Codex Alimentarius and the International Cooperation on Harmonization of Technical Requirements for Registration of Veterinary Medicinal Products (VICH).

Joint FAO/WHO Expert Committee on Food Additives. The Joint FAO/WHO Expert Committee on Food Additives is an international expert scientific committee that is administered jointly by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO). It provides a risk assessment/safety evaluation of residues of veterinary drugs in animal products, exposure and residue definition and maximum residue limit proposals for veterinary drugs. Similarly, the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) is an international expert scientific group administered jointly by the FAO and WHO. JMPR reviews residues and analytical aspects of the pesticides, estimates the maximum residue levels, reviews toxicological data and estimates acceptable daily intakes for humans of the pesticides under consideration. Elanco works with this committee to establish acceptably safe levels of residual substances in food-producing animals after treatment with veterinary drugs or pesticides. This in turn enables the calculation of appropriate withdrawal times for our products prior to an animal entering the food chain.

Advertising and Promotion Review. Promotion of animal health products is controlled by regulations in many countries. These rules generally restrict advertising and promotion to those claims and uses that have been reviewed and endorsed by the applicable agency. We conduct a review of promotion material for compliance with the local and regional requirements in the markets where we sell animal health products.

Import and Export of Products. The importation and exportation of animal health products is controlled by regulations in many countries. In some jurisdictions this may include obtaining separate permits or licenses by product or by company or filing notices with applicable regulatory agencies prior to import or export of product. We ensure compliance with local, regional and global regulations in the markets where we import/export our animal health products.

International Cooperation on Harmonization of Technical Requirements for Registration of Veterinary Medicinal Products. VICH is a trilateral (EU-Japan-U.S.) program launched in 1996 aimed at harmonizing technical requirements for veterinary product registration. Several other countries have obtained observer status, for example, Canada, New Zealand, Australia, South Africa and the U.K., or are linked to VICH on the basis of the VICH Outreach Forum, a VICH initiative with the main objective of providing a basis for wider international harmonization of technical requirements. In addition, the World Organization for Animal Health is an associate member of VICH.

Environmental, Health and Safety

We are subject to various federal, state, local and international laws and regulations concerning environmental, health, safety (EHS) and sustainability matters. These laws and regulations govern matters such as the emission and discharge of hazardous materials into the ground, air or water; the generation, use, storage, handling, treatment, packaging, transportation, exposure to and disposal of hazardous and biological materials, including recordkeeping, reporting and registration requirements; and the health and safety of our employees. Our operations necessitate obtaining and complying with various permits, registrations and other authorizations from governmental authorities, which retain the power to modify or revoke government-issued authorizations or enforce compliance through fines and injunctions.

Certain environmental laws impose joint and several liability, without regard to fault, for clean-up costs related to the disposal or release of hazardous substances into the environment. This liability may extend to both current or former Elanco owned or operated sites, as well as third-party or offsite disposal locations. While our current reserves for environmental remediation obligations are not material, we could be subject to potential liabilities for the investigation and remediation of legacy environmental contamination from historical industrial activity at sites we own or operate. We are actively monitoring and investigating such contamination at certain sites. Furthermore, in connection with past divestitures, we have assumed indemnification obligations that may require us to conduct or finance environmental clean-ups at sites we no longer own or operate. Conversely, we have also secured indemnification agreements from certain of our past acquisitions for various environmental clean-ups; however, these indemnities are limited in time and scope and may be further restricted by new information or may not be available at all.

Beyond governmental actions, private parties could assert personal injury or other claims against us due to the presence of, or exposure to, hazardous materials on, from or otherwise related to such properties. We have made, and will continue to make, necessary expenditures to ensure compliance with applicable EHS laws and regulations.

Human Capital

Employees. As of December 31, 2025, we employed approximately 9,400 full time employees and approximately 500 fixed-duration employees, which are individuals hired for a pre-defined length of time (typically one to four years). Approximately 30% of our global workforce is U.S.-based. In connection with our previously announced 2025 Restructuring Plan, we expect a global headcount reduction of approximately 300 employees, with an additional 300 positions that will be replaced with positions in growth areas or in lower-cost geographies.

At Elanco, our culture drives employee performance, and our leadership and employees are encouraged to evaluate performance with these values and behavioral pillars in mind.

Human Capital Management. Our comprehensive human capital management strategy includes talent acquisition efforts focused on attracting high-quality candidates from a variety of sources and learning, mentoring and development opportunities for all employees. We also support the continued needs of our workforce through the evolution of our benefits, including paid time off and parental leave.

We have also implemented an employee-led and leadership-supported council that influences the strategic direction of human capital management at Elanco and represents our sites and affiliates from around the world. Additionally, eight Elanco Employee Resources Groups (ERGs) are essential to delivering our promise to employees to foster an inclusive culture and are key to the success of our human capital management strategy. ERGs are unique communities of employees and their allies, offering support and professional development opportunities. Any employee is eligible to join any ERG.

Total Rewards. We invest in our workforce by offering competitive salaries, incentives and benefits. Our pay-for-performance philosophy is designed to create ownership and to help ensure we attract and retain talent, as well as reward and recognize top-performing employees through merit increases and other rewards. We benchmark our total rewards annually to ensure our compensation and benefit programs remain competitive with our peers. Our benefits are one way we support our employees’ well-being and deliver on our employee promise.

Development. We offer employees opportunities to advance their careers at Elanco and are committed to equipping employees with relevant skills and development opportunities to help them thrive and meet the ever-changing needs of customers and stakeholders across our dynamic and growing industry. Beyond professional growth, our employees actively engage in volunteer and giving initiatives aligned with our culture to Go Beyond.
