Forward-Looking Statements

This Annual Report on Form 10-K and our other publicly available documents include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 (Exchange Act), and are subject to the safe harbor created thereby under the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts, and generally can be identified by the use of words such as "may," "could," "aim," "seek," "believe," "will," "expect," "project," "estimate," "intend," "target," "anticipate," "plan," "continue," or similar expressions or future or conditional verbs.

Forward-looking statements inherently involve many risks and uncertainties that could cause actual results to differ from those expressed in forward-looking statements. Forward-looking statements are based on management's current plans and expectations, expressed in good faith and believed to have a reasonable basis. However, we can give no assurance that any expectation or belief will result or will be achieved or accomplished. Investors therefore should not place undue reliance on forward-looking statements. The following include some but not all of the factors that could cause actual results or events to differ from those anticipated:

• the significant costs and uncertainties in the pharmaceutical research and development process, including with respect to the timing and process of obtaining regulatory approvals and the ability of the company's clinical trials to meet expectations;

• the impact and uncertain outcome of acquisitions and business development transactions and related costs;

• intense competition affecting our products, pipeline, or industry;

• market uptake of launched products and indications;

• continued pricing pressures and the impact of actions of governmental and private actors affecting pricing of, reimbursement for, and patient access to pharmaceuticals, or reporting obligations related thereto;

• negotiation and implementation of our voluntary agreement with the U.S. government related to drug pricing and access;

• developments or uncertainties related to our or competitive products, including as may relate to safety or efficacy concerns;

• dependence on relatively few products or product classes for a significant percentage of our total revenue and a consolidated supply chain;

• our ability to protect and enforce patents and other intellectual property and changes in patent law or regulations related to data package exclusivity;

• information technology system inadequacies, inadequate controls or procedures, security breaches, or operating failures;

• unauthorized access, disclosure, misappropriation, or compromise of confidential information or other data stored in our information technology systems, networks, and facilities, or those of third parties with whom we share our data and violations of data protection laws or regulations;

• issues with product supply, regulatory approvals, or other negative outcomes stemming from manufacturing difficulties, disruptions, or shortages, including as a result of unpredictability and variability in demand, labor shortages, third-party performance, quality, cyber-attacks, or regulatory actions related to our and third-party facilities;

• reliance on third-party relationships and outsourcing arrangements;

• the use of artificial intelligence or other emerging technologies in various facets of our operations, including partnerships related to the use of, or the sharing of, such technologies with third parties, which may exacerbate competitive, regulatory, litigation, cybersecurity, and other risks;

• the impact of global macroeconomic conditions, including uneven economic growth or downturns or uncertainty, trade and other global disputes and interruptions, including related to tariffs, trade protection measures, and similar restrictions, international tension, conflicts, regional dependencies, or other costs, uncertainties, and risks related to engaging in business globally;

• fluctuations in foreign currency exchange rates, changes in interest rates, and inflation or deflation;

• significant and sudden declines or volatility in the trading price of our common stock and market capitalization;

• litigation, investigations, or other similar proceedings involving past, current, or future products, activities, or intellectual property;

• changes in tax law and regulation, tax rates, or events that differ from our assumptions related to tax positions;

• regulatory changes, developments, and uncertainty;

• regulatory oversight and actions regarding our operations and products;

• regulatory compliance problems or government investigations;

• risks from the proliferation of counterfeit, misbranded, adulterated, or illegally compounded products;

• actual or perceived deviation from environmental-, social-, or governance-related requirements or expectations;

• asset impairments and restructuring charges; and

• changes in accounting and reporting standards.

Investors should also carefully read the factors described under Item 1A, "Risk Factors" in this Annual Report on Form 10-K for a description of certain risks that could, among other things, cause our actual results to differ from those expressed in forward-looking statements. Investors should understand that it is not possible to predict or identify all such factors and should not consider the risks described above and under Item 1A, "Risk Factors" to be a complete statement of all potential risks and uncertainties.

All forward-looking statements speak only as of the date of this Annual Report and are expressly qualified in their entirety by the risk factors and cautionary statements included in this Annual Report. Except as is required by law, we expressly disclaim any obligation to publicly release any revisions to forward-looking statements to reflect events after the date of this Annual Report.

Part I

Eli Lilly and Company (referred to as the company, Lilly, we, or us) was incorporated in 1901 in Indiana to succeed to the drug manufacturing business founded in Indianapolis, Indiana, in 1876 by Colonel Eli Lilly. We discover, develop, manufacture, and market products in a single business segment—human pharmaceutical products.

Our purpose is to unite caring with discovery to create medicines that make life better for people around the world. Our long-term success depends on our ability to continually discover or acquire, develop, and commercialize innovative medicines.

We manufacture and distribute our products through facilities in the United States (U.S.), including Puerto Rico, and in Europe and Asia. Our products are sold in approximately 90 countries.

Products

Our products include:

In addition to the other information contained in this Annual Report on Form 10-K, the following risk factors should be considered carefully in evaluating our company. It is possible that our business, financial condition, liquidity, cash flows, results of operations, reputation, and prospects could be materially adversely affected by any of these risks. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could also adversely affect our business, financial condition, liquidity, cash flows, results of operations, reputation, and prospects.

Risks Related to Our Business and Industry

Pharmaceutical research and development is very costly and highly uncertain; we may not succeed in developing, licensing, or acquiring commercially successful products sufficient in number or value to replace revenues of products that have lost or will lose intellectual property protection or are displaced by competing products or therapies.

There are many difficulties and uncertainties inherent in pharmaceutical research and development, the introduction of new products and indications, business development activities to enhance or refine our product pipeline, and commercialization of our products.

There is a high rate of failure inherent in drug discovery and development. To bring a product from the discovery phase to market takes considerable time and entails significant cost. Failure or results that misalign with expectations can occur at any point in the process, including in later stages after substantial investment, following meaningful cost for manufacturing capabilities and inventory to prepare for launch, and after we and others may have attributed significant value for these potential products. As a result, a significant portion of funds invested in research and development programs will not generate direct financial returns. New product candidates that appear promising in development or prior to being acquired may fail to reach the market or may have only limited commercial success because of efficacy or safety concerns, inability to obtain or maintain necessary regulatory approvals or payer reimbursement or coverage, failure to obtain placement on guidelines or recommendations published by third-party organizations, the application of pricing controls, limited scope of approved uses, label changes, changes in the relevant treatment standards or the availability of newer, better, or more cost-effective competitive products, difficulty or excessive costs to manufacture, insufficient infrastructure to support detection, diagnostic or other requisites for treatment, ineffectiveness in connecting with healthcare professionals, including digitally through virtual engagements, or infringement of the patents or intellectual property rights of others. We may also fail to allocate research and development resources efficiently, fail to pursue or invest sufficiently in product candidates or indications that may have been successful, or fail to optimally balance trial design, conduct, and speed to accomplish desired outcomes.

We regularly submit new product candidates and indications to regulatory agencies for approval, including highly anticipated candidates such as orforglipron. Regulatory agencies establish high hurdles for the efficacy and safety of new products and indications. Delay, uncertainty, unpredictability, and inconsistency in drug approval processes across markets and agencies can result in delays in product launches, lost market opportunities, impairment of inventories, and other negative impacts. In addition, it can be very difficult to predict revenue growth rates of, or variability in demand for, new or future products and indications, which in some cases leads to difficulty meeting product demand or, on the other hand, lower volume growth, excess inventory, and related financial charges.

We cannot state with certainty when or whether our products and indications now under development will be approved or launched; whether, if initially granted, such approval will be maintained; whether we will be able to develop, license, or otherwise acquire additional product candidates, indications, or products; or whether our products and indications, once launched, will be commercially successful.

Through internal innovation and business development we must maintain a flow of successful products and indications or line extensions sufficient both to cover our substantial research and development costs and investments and to replace revenues that are lost as profitable products become subject to pricing controls, lose intellectual property exclusivity, are displaced by competing products, or therapies, or experience a reduction in patient access. Failure to replenish our product portfolio and pipeline in a timely manner would have a material adverse effect on our business, results of operations, cash flows, and financial position. Our dependence on, or focus in, one or more key products or product classes exacerbates this risk. In addition, the growth of our business and revenue base increases the risk that products developed or acquired by us may not provide adequate value to sustain further long-term growth.

We engage in various forms of business development activities to enhance or refine our product pipeline and development capabilities, including licensing arrangements, co-development agreements, co-promotion arrangements, distribution and promotion agreements, joint ventures, acquisitions, equity investments, and divestitures. There are substantial risks associated with identifying and competing for successful business development targets and consummating related transactions. Continued regulatory focus on business combinations in our industry, including by the Federal Trade Commission and competition authorities in Europe and other jurisdictions, and heightened competition for attractive targets has and could continue to delay, jeopardize, or increase the costs or risks of our business development activities. In addition, failures or difficulties in integrating or retaining new personnel or the operations of the businesses, products, or assets we acquire (including related technology, commercial operations, compliance programs, information security, manufacturing, distribution, and general business operations and procedures) may affect our ability to realize the potential benefits of business development transactions and may result in our incurrence of substantial asset impairment or restructuring charges. We also may fail to generate the expected revenue and pipeline enhancement from business development activities due to diligence that fails to identify risks or adequately anticipate their magnitude, unsuccessful clinical trials, issues related to the quality, integrity, or broad applicability of data, regulatory impediments, and manufacturing or commercialization challenges. Additionally, business development activity focused on new modalities may entail additional risks and costs given the high levels of scientific uncertainty inherent in novel technologies. Business development transactions may not be completed in a timely manner (if at all), may not result in successful development outcomes or successful commercialization of any product, may require additional unanticipated investments to achieve potential benefits, may give rise to legal proceedings or regulatory scrutiny, and may result in charges that negatively impact our financial position or results of operations in any given period.

See Item 1, "Business—Research and Development—Phases of New Drug Development," Item 7, "Management's Discussion and Analysis—Executive Overview—Clinical Development Pipeline" and Item 8, "Financial Statements and Supplementary Data—Note 6: Inventories," for more details about our current product pipeline.

Risk Management and Strategy

We manage cybersecurity threats as part of our oversight, evaluation, and mitigation of enterprise-level risks. We have based our cybersecurity program on industry frameworks, including, among others, the U.S. National Institute of Standards and Technology Cybersecurity Framework, with the goal of building enterprise resilience against an evolving landscape of cybersecurity threats and responding to cybersecurity threats as they materialize. Our program includes monitoring, identification, assessment, and management components, as well as information sharing and escalation components designed to inform management and the board of directors of prospective risks and developments.

Our information security program encompasses functions dedicated to both proactive and reactive management of cybersecurity threats. We implement our cybersecurity program internally through established policies, standards, reference architectures, and the use of enterprise security services that focus on emerging and ongoing cybersecurity risks. Our proactive management of cybersecurity risks entails many actions, including the maintenance of system access restrictions, utilization of data security technology, employee education and training initiatives, and retention of cyber liability insurance, among other measures. We regularly engage third-party auditors and consultants and leverage our internal audit function to assess various facets of our cybersecurity program. These engagements include completion of industry-standard assessments or certifications, maturity model reviews, threat simulations, as well as internal reviews to assess the effectiveness of our cybersecurity processes. We also maintain enterprise-wide processes to oversee and identify risks from cybersecurity threats associated with our use of third-party service providers. As examples, we generally review current and prospective third-party service providers for unacceptable cybersecurity risks, negotiate contractual provisions that require the establishment of third-party cybersecurity controls, and deploy security measures to protect third-party communications. For companies we acquire, the integration process includes plans for alignment with relevant information security policies and procedures.

We assess cybersecurity contingencies within our overall business continuity risk management planning process. Our Information Security team utilizes various tools to prevent, detect, monitor, and react to cybersecurity threats. Our Incident Response Playbook outlines processes, roles, responsibilities, engagements, escalations, notifications, and other communications applicable to the assessment, mitigation, and remediation of realized cybersecurity events. The nature and assessed risk of a realized cybersecurity event dictates the pace and extent of relevant processes, escalations, and communications, including an evaluation of any necessary or required disclosure. Roles and escalation paths range from within the Information Security team up to the Executive Committee, and the board of directors and its committees, as appropriate.

We describe certain risks faced by us from identified cybersecurity threats in Item 1A, "Risk Factors—Risks Related to Our Operations—Failure, inadequacy, breach of, or unauthorized access to, our IT systems or those of our third-party service providers, unauthorized access to our confidential information, or violations of data protection laws, could result in material harm to our business and reputation", "Risk Factors—Risks Related to Our Operations—Manufacturing, quality, or supply chain difficulties, disruptions, or shortages could lead to product supply problems or other negative outcomes", "Risk Factors—Risks Related to Our Operations—Reliance on third-party relationships and outsourcing arrangements could adversely affect our business", and "Risk Factors—Risks Related to Our Operations—Our use of artificial intelligence (AI) or other emerging technologies could adversely impact us."

Governance

Management, under the supervision of our Chief Information Security Officer (CISO), is directly responsible for assessing and managing cybersecurity risks and otherwise implementing our cybersecurity program, which includes our Incident Response Playbook. The CISO reports directly to our Chief Information and Digital Officer (CIDO), who is a member of our Executive Committee and leads our information technology, cybersecurity, digital health, and advanced analytics and data science functions. Our CIDO in turn regularly updates our Executive Committee on cybersecurity matters. Our CISO and CIDO have significant experience managing global cybersecurity threats across the pharmaceutical, technology, entertainment, and defense industries. In addition to providing regular updates to the CIDO and his staff, the CISO is a member of our Executive Information Security Governance function (EISG), which meets regularly and is composed of executive and senior leadership from a variety of functions, including information security, legal, finance, audit, and ethics and compliance to assess and manage cybersecurity developments and risks and our internal programs. Each of the CIDO, the CISO and the EISG may call upon business and legal stakeholders across our company to manage cybersecurity threats and incidents.

Our board of directors monitors cybersecurity risks and regularly participates in presentations on cybersecurity and information technology. The audit committee of our board of directors is responsible for oversight of our programs, policies, procedures, and risk management activities related to information security, cybersecurity and data protection. The audit committee meets regularly with our CIDO, CISO, and Chief Privacy Officer to discuss threats, risks, and ongoing efforts to enhance cyber resiliency, as well as changes to the broader cybersecurity landscape. In addition, the ethics and compliance committee supports the audit committee and board in oversight of legal and regulatory compliance. In addition to regular presentations, management promptly updates our board of directors regarding significant threats and incidents as they arise.

Our principal domestic and international executive offices are located in Indianapolis. We own several production, distribution, and corporate administrative sites in the U.S., including Puerto Rico. Major production sites include facilities in Indiana, North Carolina, Puerto Rico, and Wisconsin. We own several production and distribution sites in Europe and Asia. Major production sites include facilities in Ireland, France, Spain, Italy, China, and Japan. Additional U.S. and international production facilities and expansions of production facilities are expected to come online in future periods.

Our research and development facilities are primarily located in the U.S. and consist of owned facilities in Indiana and leased sites in California, Massachusetts, Colorado, and New York.

We believe that none of our properties is subject to any encumbrance, easement, or other restriction that would detract materially from its value or impair its use in the operation of the business. The buildings we own are of varying ages and in good condition.

We are a party to various currently pending legal actions, government investigations, and environmental proceedings. Information pertaining to legal proceedings is described in Item 8, "Financial Statements and Supplementary Data—Note 16: Contingencies," and incorporated by reference herein.

Not applicable.

General

Management's discussion and analysis of results of operations and financial condition is intended to assist the reader in understanding and assessing significant changes and trends related to our results of operations and financial position. This discussion and analysis should be read in conjunction with Item 8, "Financial Statements and Supplementary Data." Certain statements in this Item 7 constitute forward-looking statements. Various risks and uncertainties, including those discussed in "Forward-Looking Statements" and Item 1A, "Risk Factors," may cause our actual results, financial position, and cash generated from operations to differ from these forward-looking statements.

EXECUTIVE OVERVIEW

This section provides an overview of our financial results, our clinical development pipeline, and other matters affecting our company and industry.

Financial Results

The following table summarizes certain financial information:

Revenue increased in 2025 driven primarily by increased volume, partially offset by lower realized prices. The increased volume and lower realized prices in 2025 were primarily driven by Mounjaro and Zepbound.

Net income and earnings per share increased in 2025, primarily due to higher gross margin, partially offset by increased marketing, selling, and administrative expenses and research and development expenses.

See "Results of Operations" for additional information.

Clinical Development Pipeline

Our long-term success depends on our ability to continually discover or acquire, develop, and commercialize innovative medicines.

The following select new molecular entities (NMEs) and new indication line extension (NILEX) products are currently in clinical trials or have been submitted for regulatory review or have recently received regulatory approval in the U.S., European Union (EU), or Japan. The table reflects the status of these NMEs and NILEX products, up to the time of the filing of this Annual Report on Form 10-K:

(1) Granted a Commissioner's National Priority Voucher from the FDA.

(2) In collaboration with Almirall, S.A. in Europe.

(3) The FDA granted Breakthrough Therapy designation for olomorasib for the treatment of certain newly diagnosed metastatic KRAS G12C-mutant lung cancers and for sofetabart mipitecan for the treatment of certain patients with platinum-resistant ovarian cancer. Breakthrough Therapy designation is designed to expedite the development and review of potential medicines that are intended to treat a serious condition when preliminary clinical evidence indicates that the treatment may demonstrate substantial improvement on a clinically significant endpoint(s) over already available therapies.

There are many difficulties and uncertainties inherent in pharmaceutical research and development, the introduction of new products and indications, business development activities to enhance or refine our product pipeline, and commercialization of our products. There is a high rate of failure inherent in drug discovery and development. To bring a product from the discovery phase to market takes considerable time and entails significant cost. See Item 1A, "Risk Factors—Risks Related to Our Business and Industry—Pharmaceutical research and development is very costly and highly uncertain; we may not succeed in developing, licensing, or acquiring commercially successful products sufficient in number or value to replace revenues of products that have lost or will lose intellectual property protection or are displaced by competing products or therapies," for additional information.

We manage research and development spending across our portfolio of potential new medicines and indications. A delay in, or termination of, any one project will not necessarily cause a significant change in our total research and development spending. Due to the risks and uncertainties involved in the research and development process, we cannot reliably estimate the nature, timing, and costs of the efforts necessary to complete the development of our research and development projects, nor can we reliably estimate the future potential revenue that will be generated from any successful research and development project. Each project represents only a portion of the overall pipeline, and none is individually material to our consolidated research and development expense. While we do accumulate certain research and development costs on a project level for internal reporting purposes, we must make significant cost estimations and allocations, some of which rely on data that are neither reproducible nor validated through accepted control mechanisms. Therefore, we do not have sufficiently reliable data to report on total research and development costs by project, by pre-clinical versus clinical spend, or by therapeutic category.

Other Matters

Trends Affecting Pharmaceutical Pricing, Reimbursement, and Access and Certain Other Regulatory Developments

Global concern over access to, and affordability of, pharmaceutical products continues to drive debate and action, as well as cost containment efforts by governmental authorities and scrutiny of pricing and access disparities. Cost containment measures include the use of mandated discounts, price reporting requirements, mandated reference prices, restrictive formularies, changes to available intellectual property protections, as well as other efforts.

Reforms, initiatives, and other actions, including those that may stem from political initiatives, periods of uneven economic growth or downturns, or as a result of inflation or deflation, trade and other global disputes and interruptions including related to tariffs, trade protection measures, and similar restrictions, the emergence or escalation of, and responses to, international tension and conflicts, or government budgeting priorities, are expected to continue to result in added pressure on cost, pricing, reimbursement, and access for our products.

In November 2025, we announced preliminary voluntary agreements with the U.S. government in which, among other arrangements, we agreed to lower Medicaid and certain other drug prices for U.S. patients and to launch new medicines with a more balanced pricing approach across developed nations. We face risks and uncertainty associated with these arrangements and negotiating the definitive agreements, including potential delays and the possibility of unfavorable terms related to pricing, access, and other key objectives. Among other risks, we may fail to adequately capitalize on the additional U.S. access to our obesity medicines resulting from these agreements, particularly if the revenues generated from such expanded access are insufficient to offset pricing concessions. Moreover, the outcome of these arrangements and broader U.S. policy efforts to align domestic pharmaceutical pricing with international benchmarks from countries with competing healthcare cost containment priorities is uncertain and could negatively impact our pricing strategies, product demand or access, or competitive positioning across global markets, and may result in reduced revenue in certain markets.

Other policies, regulations, legislation, or enforcement, including those proposed or pursued by lawmakers, regulators, and other authorities in the U.S. and worldwide, have and may continue to adversely impact our business and consolidated results of operations.

The IRA requires HHS to effectively set prices for certain single-source drugs and biologics reimbursed under Medicare Part B and Part D. Currently, these government prices generally apply beginning at nine years (for medicines approved under a New Drug Application) or thirteen years (for medicines approved under a Biologics License Application) following FDA approval or licensure for the molecule. In August 2023, HHS selected Jardiance, which is part of our collaboration with Boehringer Ingelheim, as one of the first ten medicines subject to government-set prices effective in 2026. In January 2026, HHS selected Trulicity and Verzenio as additional medicines subject to government-set prices to be effective in 2028. Given our product portfolio, we expect other significant products will be selected in future years. The IRA has, and will continue to, meaningfully influence our business strategies and those of our competitors and could significantly impact our business and consolidated results of operations.

The U.S. and other countries have recently imposed or reached alignment on new tariffs. In some cases, imposed tariffs have been paused but may come into effect quickly and unpredictably. While pharmaceuticals are exempt from certain of these tariffs, such exemptions may be terminated or may not apply to any future tariffs. The precise impact of tariffs, trade protection measures, and other restrictions depend on their ultimate scope, timing, and other factors. If enacted, additional restrictions could result in supply disruptions or delays, further increase costs, or otherwise have a negative impact on our business. Given the nature of pharmaceutical regulation and commercialization, we may not be able to share the burden of increased costs from tariffs and related impacts to any meaningful degree.

Private payers and pharmacy benefit managers in the U.S. continue to significantly impact the market for pharmaceuticals through negotiation of access, manufacturer price or rebate concessions and pharmacy reimbursement rates. Restrictive or unfavorable pricing, coverage, or reimbursement determinations for our medicines or product candidates by governments, regulatory agencies, courts, or private actors have and may continue to adversely impact our business and consolidated results of operations. In addition, we are engaged in litigation and investigations related to the 340B program, access to insulin, pricing, product safety, and other matters that, if resolved adversely to us, could negatively impact our business and consolidated results of operations. It is not currently possible to predict the overall potential adverse impact to us or the general pharmaceutical industry of continued cost containment efforts worldwide.

In addition, regulatory issues concerning compliance with current Good Manufacturing Practices, quality assurance, safety signals, evolving standards, and increased scrutiny around excipients and potential impurities such as nitrosamines, and similar regulations and standards (and comparable foreign regulations and standards) for our products in some cases lead to regulatory and legal actions, product recalls and seizures, fines and penalties, interruption of production leading to product shortages, import bans or denials of import certifications, inability to realize the benefit of capital expenditures, or delays or denials in new product approvals, line extensions or supplemental approvals of current products pending resolution of the issues, or other negative impacts, any of which result in reputational harm or adversely affect our business.

Incretin Medicines

Mounjaro and Zepbound accounted for 56 percent of our total revenues in 2025 and we expect cardiometabolic health products will continue to represent a significant and growing portion of our business, revenues, and prospects. In 2025, we reached preliminary drug pricing agreements with the U.S. government. As part of these agreements, Medicare beneficiaries will have access to discounted Lilly obesity medicines by July 1, 2026 and individual state Medicaid programs will have the option to expand access to these medicines. Also in 2025, we received a U.S. Commissioner’s National Priority Voucher for our product candidate orforglipron for the treatment of obesity, and we submitted to the FDA under that expedited review pathway. Internationally, we launched Mounjaro in all major markets. To support anticipated demand for our current and prospective products, we have undertaken significant manufacturing expansion initiatives. Additional capacity is expected to become operational over the next several years.

We expect our near-term financial performance will be impacted by, among other factors, the timing of potential regulatory approvals for orforglipron and U.S. Medicare access for Zepbound (and, if approved, orforglipron), as well as the demand and pace of uptake in new incretin channels and markets. More generally, incretin volume fluctuations due to channel dynamics or demand can have a disproportionate impact on our results of operations in any given period. Longer term, the durability of our cardiometabolic health product offerings and sustainability of our growth and prospects will depend on our ability to maintain or strengthen our competitive position as the therapeutic landscape evolves and to deliver further innovations that provide sufficient value to sustain our growth momentum.

We continue to see the production, marketing, and sale of counterfeit, misbranded, adulterated, and mass-compounded incretins. These practices may impact patient safety and undermine regulatory drug approval processes. While the FDA confirmed in late 2024 that the previous shortage of tirzepatide had ended and that compounding pharmacies are required to cease mass production, we cannot guarantee adequate regulation or compliance. Lilly will continue to consider all options, including filing lawsuits where appropriate, to address unlawful practices and the patient safety risks of unapproved, untested, and manipulated drugs.

Tax Matters

We are subject to income taxes and various other taxes in the U.S. and in many foreign jurisdictions; therefore, changes in both domestic and international tax laws or regulations have affected and may affect our effective tax rate, results of operations, and cash flows. The U.S. and countries around the world are actively proposing and enacting tax law changes. Further, actions taken with respect to tax-related matters by associations such as the OECD and the European Commission could influence tax laws in countries in which we operate. Tax authorities in the U.S. and other jurisdictions in which we do business routinely examine our tax returns and are expected to increase their scrutiny of cross-border tax issues. Changes to existing U.S. and foreign tax laws and increased scrutiny by tax authorities in the U.S. and other jurisdictions could have a material adverse impact on our future consolidated results of operations and cash flows.

In July 2025, the One Big Beautiful Bill Act (OBBBA), which implemented certain U.S. tax law changes, was enacted into law. The OBBBA modified and made permanent several provisions of the Tax Cuts and Jobs Act, including reductions in scheduled increases for the rate of taxation of foreign income, immediate deductibility of U.S. research and development expenses, and reinstatement of 100 percent bonus depreciation for capital assets.

Acquisitions

We invest in external research and technologies and manufacturing capabilities that we believe complement and strengthen our own efforts. These investments can take many forms, including acquisitions, collaborations, investments, and licensing arrangements. We view our business development activity as a way to enhance or refine our pipeline and strengthen our business.

Continued regulatory focus on business combinations in our industry, including by the Federal Trade Commission and competition authorities in Europe and other jurisdictions, could continue to delay, jeopardize, or increase the costs of our business development activities and may negatively impact our consolidated financial position or results of operations.

Foreign Currency Exchange Rates

As a global company, we face foreign currency risk exposure from fluctuating currency exchange rates, primarily the U.S. dollar against the euro, Japanese yen, Chinese yuan, and British pound sterling. While we seek to manage a portion of these exposures through hedging and other risk management techniques, significant fluctuations in currency rates can have a material impact, either positive or negative, on our consolidated results of operations in any given period. There is uncertainty in the future movements in foreign currency exchange rates, and fluctuations in these rates have and could adversely impact our consolidated results of operations and cash flows.

Other Factors

Other factors have had, and may continue to have, an impact on our consolidated results of operations. These factors include cost and wage inflation, supply chain and labor market complexities, international tension and conflicts, uneven economic growth, downturns or uncertainty, risks related to engaging in business globally, including legislation and regulatory action in or regarding foreign jurisdictions, and fluctuations due to channel dynamics or demand for certain products.

See Item 1, "Business" and Item 1A, "Risk Factors," and Notes 4, 14, and 16 to the consolidated financial statements for additional information and risks and uncertainties that could impact our business and operations, including the matters described within this Executive Overview.

RESULTS OF OPERATIONS

Operating Results—2025

Revenue

The following table summarizes our revenue activity by region:

The following are components of the change in revenue compared with the prior year:

In the U.S., the volume increase and the lower realized prices in 2025 were primarily driven by Mounjaro and Zepbound.

Outside the U.S., the volume increase in 2025 was primarily driven by Mounjaro.

The following table summarizes our revenue, including net product revenue and collaboration and other revenue, by product in 2025 compared with 2024:

(1) Tirzepatide is marketed for obesity under the brand name Zepbound in Canada, Japan, and the U.S.

Revenue of Mounjaro increased 53 percent in the U.S., driven by strong demand, partially offset by lower realized prices. Revenue outside of the U.S. was $9.3 billion in 2025 compared to $2.6 billion in 2024, primarily driven by volume growth.

Revenue of Zepbound increased 174 percent in the U.S., driven by increased demand, partially offset by lower realized prices.

Revenue of Verzenio increased 1 percent in the U.S. Revenue outside the U.S. increased 20 percent, driven by volume growth.

Gross Margin, Costs, and Expenses

The following table summarizes our gross margin, costs, and expenses:

Gross margin as a percent of revenue in 2025 increased 1.7 percentage points compared with 2024, primarily driven by favorable product mix and improved cost of production, partially offset by lower realized prices.

Research and development expenses increased 21 percent in 2025, primarily driven by continued investments in our early and late-stage portfolio.

Marketing, selling, and administrative expenses increased 29 percent in 2025, primarily driven by promotional efforts supporting ongoing and planned launches.

Acquired in-process research and development (IPR&D) charges recognized in 2025 were primarily related to the acquisitions of Scorpion Therapeutics, Inc.'s (Scorpion) PI3Kα inhibitor program STX-478 and of SiteOne Therapeutics, Inc. (SiteOne). Acquired IPR&D charges recognized in 2024 were primarily related to the acquisition of Morphic Holding, Inc. (Morphic). See Note 4 to the consolidated financial statements for additional information.

Our effective tax rate was 19.8 percent in 2025 compared with an effective tax rate of 16.5 percent in 2024, primarily driven by unfavorable impacts related to the jurisdictional mix of earnings and U.S. tax law changes in 2025 relative to 2024. The effective tax rates for both periods were unfavorably impacted by non-deductible acquired IPR&D charges, with a larger impact occurring in 2024. See Note 14 to the consolidated financial statements for additional information.

Operating Results—2024

For a discussion of our results of operations pertaining to 2024 and 2023 see Item 7, "Management's Discussion and Analysis of Results of Operations and Financial Condition" in our Annual Report on Form 10-K for the year ended December 31, 2024.

FINANCIAL CONDITION AND LIQUIDITY

We believe our available cash and cash equivalents, together with our ability to generate operating cash flow and our access to short-term and long-term borrowings, are sufficient to fund our existing and planned capital requirements, which include:

• working capital requirements, including related to employee payroll and benefits, clinical trials, manufacturing materials, and taxes;

• capital expenditures;

• share repurchases and dividends;

• repayment of outstanding short-term and long-term borrowings;

• milestone and royalty payments; and

• potential business development activities, including acquisitions, collaborations, investments, and licensing arrangements.

Our management continuously evaluates our liquidity and capital resources, including our access to external capital, to ensure we can adequately and efficiently finance our capital requirements. As of December 31, 2025, our material cash requirements primarily related to purchases of goods and services to produce our products and conduct our operations, income tax payments, capital expenditures, dividends, milestone and royalty payments, business development activities, share repurchases and repayment of outstanding borrowings (see Notes 14, 3, 4, 13, and 11 to the consolidated financial statements). We anticipate our cash requirements related to ordinary course purchases of goods and services will be consistent with our past levels relative to revenues.

Capital expenditures were $7.8 billion during 2025, compared to $5.1 billion in 2024. We are making investments in global facilities to manufacture existing and future products. These investments, and other capital investments that support our operations, have increased our capital expenditures and will result in meaningfully higher capital expenditures in the near term.

As we expand our manufacturing capacity in order to meet existing and expected demand of our medicines, we have entered, and expect to continue to enter, into various agreements for contract manufacturing and for supply of materials. Executed agreements related to our medicines in development could, under certain circumstances, require us to pay up to approximately $10 billion if we do not purchase specified amounts of goods or services over the durations of the agreements, which are generally up to 8 years.

Cash and cash equivalents increased to $7.3 billion as of December 31, 2025, compared with $3.3 billion at December 31, 2024. Net cash provided by operating activities increased to $16.8 billion in 2025, compared with $8.8 billion in 2024. Refer to the consolidated statements of cash flows for additional information on the significant sources and uses of cash for the years ended December 31, 2025 and 2024.

In addition to our cash and cash equivalents, we held total investments of $2.9 billion and $3.4 billion as of December 31, 2025 and 2024, respectively. As of December 31, 2025, we had approximately $902 million of unfunded commitments to invest in venture capital funds, which we anticipate will be paid over a period of up to 10 years. See Note 7 to the consolidated financial statements for additional information.

We paid $3.0 billion in 2025 for acquired IPR&D primarily related to the acquisitions of Scorpion's PI3Kα inhibitor program STX-478 and of SiteOne. We paid $3.3 billion in 2024 for acquired IPR&D primarily related to the acquisition of Morphic. See Note 4 to the consolidated financial statements for additional information.

As part of our business development activities in 2026, we have entered into acquisition agreements, subject to closing conditions. Potential amounts payable at closing for these pending acquisitions would be less than $3 billion.

As of December 31, 2025, total debt was $42.5 billion, an increase of $8.9 billion compared with $33.6 billion at December 31, 2024. See Note 11 to the consolidated financial statements for additional information.

As of December 31, 2025, we had a total of $10.1 billion of unused committed bank credit facilities, $10.0 billion of which is available to support our commercial paper program. See Note 11 to the consolidated financial statements for additional information. We believe that amounts accessible through existing commercial paper markets should be adequate to fund short-term borrowing needs.

Dividends of $6.00 per share and $5.20 per share were paid in 2025 and 2024, respectively. The quarterly dividend was increased to $1.73 per share effective for the dividend to be paid in the first quarter of 2026, resulting in an indicated annual rate for 2026 of $6.92 per share.

In 2025, we repurchased $4.1 billion of shares under our $15.0 billion share repurchase program that our board authorized in December 2024. As of December 31, 2025, we had $10.9 billion remaining under this program. See Note 13 to the consolidated financial statements for additional information.

Both domestically and abroad, we monitor the potential impacts of the economic environment and international tension and conflicts; the creditworthiness of our wholesalers and other customers, including foreign government-backed agencies and suppliers; the uncertain impact of healthcare legislation; and various international government funding levels.

In the normal course of business, our operations are exposed to fluctuations in interest rates, currency values, and fair values of equity securities. These fluctuations impact the costs of financing, investing, and operating our business. We seek to address a portion of these risks through a controlled program of risk management that includes the use of derivative financial instruments. The objective of this risk management program is to limit the impact on earnings of fluctuations in interest and currency exchange rates. All derivative activities are for purposes other than trading.

Our primary interest rate risk exposure results from changes in short-term U.S. dollar interest rates. In an effort to manage interest-rate exposures, we may enter into derivative contracts to achieve an acceptable balance between fixed- and floating-rate debt or to reduce cash flow variability from changes in interest rates as part of anticipated debt issuances. Based on our overall interest rate exposure at December 31, 2025 and 2024, including derivatives and other interest rate risk-sensitive instruments, a hypothetical 10 percent change in interest rates applied to the fair value of the instruments as of December 31, 2025 and 2024, respectively, would not have a material impact on earnings, cash flows, or fair values of interest rate risk-sensitive instruments over a one-year period.

Our foreign currency risk exposure results from fluctuating currency exchange rates, primarily the U.S. dollar against the euro, Japanese yen, Chinese yuan, and British pound sterling. We face foreign currency exchange exposures when we enter into transactions arising from subsidiary trade and loan payables and receivables denominated in foreign currencies. We also face currency exposure that arises from translating the results of our global operations to the U.S. dollar at exchange rates that have fluctuated from the beginning of the period. We in some cases enter into foreign currency forward or option derivative contracts to reduce the effect of fluctuating currency exchange rates. Our corporate risk-management policy outlines the minimum and maximum hedge coverage of such exposures. Gains and losses on these derivative contracts offset, in part, the impact of currency fluctuations on the existing assets and liabilities. We periodically analyze the fair values of the outstanding foreign currency derivative contracts to determine their sensitivity to changes in foreign exchange rates. As of December 31, 2025 and 2024, a hypothetical 10 percent change in currency exchange rates (primarily against the U.S. dollar) applied to the fair values of our outstanding foreign currency derivative contracts and the underlying assets and liabilities would not have a material impact on earnings, cash flows, or financial position over a one-year period.

Our fair value risk exposure relates primarily to our public equity investments and to our equity investments that do not have readily determinable fair values. As of December 31, 2025 and 2024, a hypothetical 10 percent change in fair value of the equity instruments would not have a material impact on earnings, cash flows, or financial position over a one-year period.

We have no off-balance sheet arrangements that have a material current effect or that are reasonably likely to have a material future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources. We acquire and collaborate on potential products still in development and enter into research and development arrangements with third parties that often require milestone and royalty payments to the third-party contingent upon the occurrence of certain future events linked to the success of the asset in development. Milestone payments may be required contingent upon the successful achievement of an important point in the development life cycle of the pharmaceutical product (e.g., approval for marketing by the appropriate regulatory agency or upon the achievement of certain sales levels). If required by the arrangement, we may make royalty payments based upon a percentage of the sales of the product in the event that regulatory approval for marketing is obtained.

Individually, these arrangements are generally not material in any one annual reporting period. However, if milestones for multiple products covered by these arrangements were reached in the same reporting period, the aggregate expense or aggregate milestone payments made could be material to our results of operations or cash flows, respectively, in that period. See Note 3 to the consolidated financial statements for additional information. These arrangements often give us the discretion to unilaterally terminate development of the product, which would allow us to avoid making the contingent payments; however, we are unlikely to cease development if the compound successfully achieves milestone objectives. We view these payments as positive because they signify that the product is successfully moving through development and is now generating or is more likely to generate cash flows from sales of products.

APPLICATION OF CRITICAL ACCOUNTING ESTIMATES

In preparing our financial statements in accordance with accounting principles generally accepted in the U.S., we must often make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. Some of those judgments can be subjective and complex, and consequently actual results could differ from those estimates. For any given individual estimate or assumption we make, it is possible that other people applying reasonable judgment to the same facts and circumstances could develop different estimates. We believe that, given current facts and circumstances, it is unlikely that applying any such other reasonable judgment would cause a material adverse effect on our consolidated results of operations, financial position, or liquidity for the periods presented in this Annual Report on Form 10-K. Our most critical accounting estimates have been discussed with our audit committee and are described below.

Revenue Recognition and Sales Rebate, Discount, and Return Accruals

Background and Uncertainties

We recognize revenue primarily from two different types of contracts, product sales to customers (net product revenue) and collaborations and other arrangements. For product sales to customers, provisions for rebates, discounts, and returns are established in the same period the related product sales are recognized. Contracts with direct and indirect customers may provide for various rebates and discounts, which we estimate as a reduction of net product revenue at the time we recognize a sale to a direct customer. Significant judgments are required in making these estimates. The largest of our sales rebate and discount amounts include rebates associated with sales covered by managed care, Medicare, Medicaid, and chargeback programs, as well as reductions in revenue related to our patient assistance programs, in the U.S. In determining the appropriate accrual amount, we consider our historical payments for these programs by product as a percentage of our historical sales, any significant changes in sales trends, an evaluation of the current contracts for these programs, the percentage of our products that are sold via these programs, and our product pricing. Since there is a timing lag between the product sale and the settlement of accruals related to these programs, our net product revenue may incorporate revisions of accruals for several periods.

Refer to Note 2 to the consolidated financial statements for further information on revenue recognition and sales return, rebate, and discount accruals.

Revenue recognized from collaborations and other arrangements includes our share of profits from the collaborations, as well as royalties, upfront and milestone payments we receive under these types of contracts.

Financial Statement Impact

We believe that our accruals for sales rebates, discounts, and returns are reasonable and appropriate based on current facts and circumstances. Our rebate and discount liabilities are included in sales rebates and discounts on our consolidated balance sheet. Our sales return liability is included in other current liabilities and other noncurrent liabilities on our consolidated balance sheet. As of December 31, 2025, a 5 percent change in our consolidated sales return, rebate, and discount liability would result in a change in revenue of approximately $897 million.

The portion of our consolidated sales rebate, discount, and return liability balances resulting from sales of our products in the U.S. was approximately 87 percent and 90 percent as of December 31, 2025 and 2024, respectively.

The following represents a roll-forward of our most significant U.S. sales rebate, discount, and return liability balances, including managed care, Medicare, Medicaid, chargeback, and patient assistance programs:

(1) Adjustments of the estimates for these rebates, discounts, and returns to actual results were less than 2 percent of consolidated revenue for each of the years presented.

Litigation Liabilities and Other Contingencies

Background and Uncertainties

Litigation liabilities and other contingencies are, by their nature, uncertain and based upon complex judgments and probabilities. The factors we consider in developing our litigation liability reserves and other contingent liability amounts include the merits and jurisdiction of the litigation, the nature and the number of other similar current and past matters, the nature of the product and the current assessment of the science subject to the litigation, as applicable, and the likelihood of settlement and current state of settlement discussions, if any. In addition, we accrue for certain product liability claims incurred but not filed to the extent we can formulate a reasonable estimate of their costs based primarily on historical claims experience and data regarding product usage.

We also consider the insurance coverage we have to diminish the exposure for periods covered by insurance. In assessing our insurance coverage, we consider the policy coverage limits and exclusions, the potential for denial of coverage by the insurance company, the financial condition of the insurers, and the possibility of and length of time for collection. The ability to insure against such exposures is limited, and due to a very restrictive market for liability insurance we are predominantly self-insured for liability losses for all our currently and previously marketed products. In addition to insurance coverage, we consider any third-party indemnification to which we are entitled or under which we are obligated. With respect to our third-party indemnification rights, these considerations include the nature of the indemnification, the financial condition of the indemnifying party, and the possibility of and length of time for collection.

The litigation accruals and environmental liabilities and the related estimated insurance recoverables are reflected on a gross basis as liabilities and assets, respectively, on our consolidated balance sheets.

Acquisitions

Background and Uncertainties

To determine whether acquisitions or licensing transactions should be accounted for as a business combination or as an asset acquisition, we make certain judgments, which include assessing whether the acquired set of activities and assets would meet the definition of a business under the relevant accounting rules.

If the acquired set of activities and assets meets the definition of a business, assets acquired and liabilities assumed are required to be recorded at their respective fair values on our consolidated balance sheet as of the acquisition date. The excess of the purchase price over the fair value of the acquired net assets, where applicable, is recorded as goodwill. If the acquired set of activities and assets does not meet the definition of a business, the transaction is recorded as an acquisition of assets and, therefore, any acquired IPR&D that does not have an alternative future use is charged to acquired IPR&D on our consolidated statement of operations at the acquisition date, and goodwill is not recorded. See Note 4 to the consolidated financial statements for additional information.

The judgments made in determining estimated fair values assigned to assets acquired and liabilities assumed in a business combination, as well as estimated asset lives, can materially affect our consolidated results of operations. The fair values of intangible assets, including acquired IPR&D, are determined using information available near the acquisition date based on estimates and assumptions that are deemed reasonable by management. Significant estimates and assumptions include, but are not limited to, probability of technical success, revenue projections, and discount rate. Depending on the facts and circumstances, we may deem it necessary to engage an independent valuation expert to assist in valuing significant assets and liabilities.

The fair values of identifiable intangible assets are primarily determined using the "income method," as described in Note 8 to the consolidated financial statements.

The fair value of any contingent consideration liability that results from a business combination is primarily determined using a discounted cash flow analysis. Estimating the fair value of contingent consideration requires the use of significant estimates and judgments, including, but not limited to, probability of technical success, timing of the potential milestone event, and the discount rate.

Financial Statement Impact

As of December 31, 2025, a 5 percent change in the contingent consideration liabilities would not result in a material impact on earnings or financial position.

Impairment of Indefinite-Lived and Long-Lived Assets

Background and Uncertainties

We review the carrying value of long-lived assets (both intangible and tangible) for potential impairment whenever events or changes in circumstances indicate the carrying value of an asset (or asset group) may not be recoverable. We identify impairment by comparing the projected undiscounted cash flows to be generated by the asset (or asset group) to its carrying value. If an impairment is identified, a loss is recorded equal to the excess of the asset's net book value over its fair value, and the cost basis is adjusted.

Goodwill and indefinite-lived intangible assets are reviewed for impairment at least annually, or more frequently if impairment indicators are present, by first assessing qualitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount. If we conclude it is more likely than not that the fair value is less than the carrying amount, a quantitative test that compares the fair value of the intangible asset to its carrying value is performed to determine the amount of any impairment.

Several methods may be used to determine the estimated fair value of long-lived assets, all of which require multiple assumptions. When determining the fair value of indefinite-lived acquired IPR&D as well as the fair value of finite-lived intangible assets for impairment testing purposes, we utilize the "income method," as described in Note 8 to the consolidated financial statements.

For acquired IPR&D assets, the risk of failure has been factored into the fair value measure and there can be no certainty that these assets ultimately will yield a successful product, as discussed previously in "—Executive Overview—Clinical Development Pipeline." The nature of the pharmaceutical business is high-risk and requires that we invest in a large number of projects to maintain a successful portfolio of approved products. As such, it is likely that some acquired IPR&D assets will become impaired in the future.

Estimates of future cash flows, based on what we believe to be reasonable and supportable assumptions and projections, require management's judgment. Actual results could vary materially from these estimates.

Income Taxes

Background and Uncertainties

We file tax returns based upon our interpretation of tax laws and regulations, and we record estimates in our financial statements based upon these interpretations at the applicable tax rates in the jurisdictions in which we operate. Our tax returns are routinely subject to examination by taxing authorities, which could result in future tax, interest, and penalty assessments. Inherent uncertainties also exist in estimates of many tax positions due to the complexity of tax laws. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution. The amount of unrecognized tax benefits is adjusted for changes in facts and circumstances such as changes to existing tax law, the issuance of regulations by taxing authorities, new information obtained during a tax examination, or resolution of a tax examination. We believe our estimates for uncertain tax positions are both appropriate and sufficient to pay assessments that may result from examinations of our tax returns; however, given the uncertainty of positions that could be taken by taxing authorities during the examinations of our tax returns, the ultimate outcome of any tax matters may result in liabilities that are greater than amounts accrued. We recognize both accrued interest and penalties related to unrecognized tax benefits in income tax expense.

We have recorded valuation allowances against certain of our deferred tax assets, primarily those that have been generated from net operating losses, tax credits, and other tax carryforwards in certain taxing jurisdictions, when the amount of future taxable income is unlikely to support their utilization.

Financial Statement Impact

As of December 31, 2025, a 5 percent change in the amount of uncertain tax positions and the valuation allowance would result in a change in net income of $160 million and $61 million, respectively.

Evaluation of Disclosure Controls and Procedures

Under applicable Securities and Exchange Commission (SEC) regulations, management of a reporting company, with the participation of the principal executive officer and principal financial officer, must periodically evaluate the company's "disclosure controls and procedures," which are defined generally as controls and other procedures designed to ensure that information required to be disclosed by the reporting company in its periodic reports filed with the SEC (such as this Form 10-K) is recorded, processed, summarized, and reported on a timely basis.

Our management, with the participation of David Ricks, president and chief executive officer, and Lucas Montarce, executive vice president and chief financial officer, evaluated our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of December 31, 2025, and concluded that they were effective.

Management's Report on Internal Control over Financial Reporting

Mr. Ricks and Mr. Montarce provided a report on behalf of management on our internal control over financial reporting, in which management concluded that the company's internal control over financial reporting is effective at December 31, 2025 based on the framework in "Internal Control—Integrated Framework" (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States. Due to the inherent limitations, no evaluation over internal control can provide absolute assurance that no material misstatements or fraud exist.

In addition, Ernst & Young LLP, the company's independent registered public accounting firm, issued an attestation report on the company's internal control over financial reporting as of December 31, 2025.

See Item 8 for the full text of management's report and Ernst & Young's attestation report.

Changes in Internal Control over Financial Reporting

During the fourth quarter of 2025, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

During the three months ended December 31, 2025, none of our directors or officers adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408 of Regulation S-K.

Not applicable.
