# Eli Lilly and Company: 10-K Risk Factor Changes 2026 vs 2025 > Source: U.S. Securities and Exchange Commission (EDGAR) > Generated: 2026-05-05 > All data extracted directly from official filings. No hallucinated content. > **[AI-Generated Summary]** The paragraph below was produced by a language > model and may contain errors. All other content on this page is deterministically > extracted from the original SEC filing. > Eli Lilly updated its disclosures to reflect that its blockbuster drugs (like Mounjaro and Zepbound) now account for 82% of revenue, making the company far more dependent on a shrinking product portfolio while simultaneously expanding manufacturing to meet exploding demand. More broadly, the company is signaling real concern about government price controls, supply chain vulnerabilities tied to geopolitical tension with China, and competitive pressure from AI-enabled drug discovery - suggesting Lilly sees its near-term risk as execution (can it actually make enough of these drugs?) and its long-term risk as staying ahead in a world where innovation is getting faster and cheaper. --- ## Summary | Status | Count | |--------|-------| | New risks added | 0 | | Risks removed | 0 | | Risks modified | 10 | | Unchanged | 6 | --- ## Modified Risk: Our use of artificial intelligence (AI) or other emerging technologies could adversely impact us. **Key changes:** - Updated: "We deploy AI and other emerging technologies in various facets of our operations and we continue to explore the development and use of AI technologies." - Updated: "The algorithms and models utilized in AI systems may have limitations, including biases, errors, insufficient or erroneous training data, or inability to handle certain data types or scenarios or to render explainable or effective outputs." - Updated: "The emergence and continued expansion of AI and other technologies may exacerbate other risks, including those related to competition, regulation, litigation, compliance issues, ethical concerns, confidentiality, and data privacy or security." - Updated: "These and other developing obligations create uncertainty and may prevent or make it harder for us to conduct or enhance our business using AI, or lead to regulatory fines, penalties, or other liability." **Prior (2025):** We deploy AI and other emerging technologies in various facets of our operations and we continue to explore further use cases for AI. The rapid advancement of these technologies presents opportunities for us in research, manufacturing, commercialization, and other business endeavors but also entails risks, including that AI-generated content, analyses, or recommendations we utilize could be deficient, or that our competitors may more quickly or effectively adopt AI capabilities. Our use of AI or other emerging technologies could also exacerbate regulatory, cybersecurity and other significant risks. Effective development, management, and use of AI technologies is novel and complex, and there are technical challenges associated with achieving desired levels of accuracy, efficiency, and reliability. The algorithms and models utilized in AI systems may have limitations, including biases, errors, or inability to handle certain data types or scenarios or to render explainable outputs. Furthermore, there are risks associated with the fact that the platforms providing AI models are in many cases owned and operated by emerging companies with less contractual and compliance sophistication. These factors may undermine our ability to effectively utilize AI or create competitive disadvantages should our competitors more skillfully make use of AI capabilities. Further, if we are unable to effectively manage the use of AI technologies by our employees, our confidential information, intellectual property, or reputation could be put at risk. The emergence of AI and other technologies may exacerbate other risks, including those related to regulation, litigation, compliance issues, ethical concerns, confidentiality, and data privacy or security. For example, regulatory uncertainty related to AI or other emerging technologies may require significant resources to adjust business practices to comply with developing laws. Several governmental authorities have already proposed or enacted laws and other guidance governing AI, such as the EU Artificial Intelligence Act. These and other developing obligations may prevent or make it harder for us to conduct or enhance our business using AI, or lead to regulatory fines, penalties, or other liability. Further, use of AI technologies could lead to unintended consequences, such as data leakage, healthcare fraud and abuse, cybersecurity incidents, intellectual property infringement, or unintended biases. **Current (2026):** We deploy AI and other emerging technologies in various facets of our operations and we continue to explore the development and use of AI technologies. We have also entered into, and may continue to enter into, partnerships and collaborations relating to the use of AI technology to aid in drug discovery and other efforts. The rapid advancement of these technologies presents opportunities for us in research, manufacturing, commercialization, and other business endeavors but also entails risks, including that AI-generated content, 34 34 34 analyses, or recommendations we utilize could be inadequate, or that our competitors may more quickly or effectively adopt AI capabilities. There are significant risks involved in developing and deploying AI, and there can be no assurance that our usage of AI or our significant investments in AI will enhance our products or services or be beneficial to our business, including our efficiency or profitability. Our use of AI or other emerging technologies could also exacerbate regulatory, cybersecurity, and other significant risks. Effective development, management, and use of AI technologies is novel and complex, and there are technical challenges associated with achieving desired levels of accuracy, efficiency, and reliability. The algorithms and models utilized in AI systems may have limitations, including biases, errors, insufficient or erroneous training data, or inability to handle certain data types or scenarios or to render explainable or effective outputs. Furthermore, there are risks associated with the fact that the platforms providing AI models are in some cases owned and operated by emerging companies with less contractual, business, and compliance sophistication. These factors may undermine our ability to effectively utilize AI or create competitive disadvantages should our competitors more skillfully make use of AI capabilities. Further, if we are unable to effectively manage the use of AI technologies by our employees, our confidential information, intellectual property, or reputation could be put at risk. The emergence and continued expansion of AI and other technologies may exacerbate other risks, including those related to competition, regulation, litigation, compliance issues, ethical concerns, confidentiality, and data privacy or security. AI may enable new competitors in drug discovery and enhance the capabilities of existing competitors, thereby broadening and intensifying competitive dynamics. In addition, developing laws and regulations related to AI or other emerging technologies create uncertainty, may require significant resources to adjust business practices for compliance, and in some cases, may limit our ability to use AI-based software. Several governmental authorities have already proposed or enacted laws and other guidance governing AI, such as the EU Artificial Intelligence Act. These and other developing obligations create uncertainty and may prevent or make it harder for us to conduct or enhance our business using AI, or lead to regulatory fines, penalties, or other liability. Further, use of AI technologies could lead to unintended consequences, such as data leakage, healthcare fraud and abuse, cybersecurity incidents, intellectual property infringement, or unintended biases. --- ## Modified Risk: Our long-term success depends on intellectual property protection; if our intellectual property rights are invalidated, circumvented, or weakened, our business will be adversely affected. **Key changes:** - Updated: "For example, an agreement-in-principle announced in December 2025 between the European Commission, Council and Parliament to revise the EU's general pharmaceutical legislation would make conditional the length of certain pharmaceutical intellectual property incentives, including by reductions in maximum data protection periods." - Updated: "In addition, a separate IPR process currently allows competitors or others to seek invalidation of patents at the USPTO without the protections of the BPCIA or Hatch-Waxman Act." - Updated: "The USPTO issued procedures regarding the discretionary denial by the Director of institution of IPR proceedings based on the agency's workload and priorities." - Updated: "If successful, such claims could result in our being unable to market a product in a particular territory or require payment of significant damages for past infringement or royalties on future sales." **Prior (2025):** Our long-term success depends on our ability to continually discover or acquire, develop, and commercialize innovative medicines. Without strong intellectual property protection, we would be unable to generate the returns necessary to support our significant investments in research and development, as well as the other expenditures required to bring new medicines and indications to the market. Intellectual property protection varies throughout the world and is subject to change over time, depending on local laws and regulations. Changes to such laws, regulations, and enforcement practices could reduce protections for our innovative products and indications. For example, a proposal by the European Commission to revise the EU's general pharmaceutical legislation threatens the predictability and length of certain pharmaceutical intellectual property incentives, including by proposed reductions in data protection periods. Changes proposed by the USPTO and by certain bills in Congress to limit the number of, and differences between, patents obtained could also affect the scope of patent protection for our products in the U.S. In recent years, U.S. government officials have proposed the exercise of "march-in-rights" and various other measures that, if enacted, could have a negative impact on our patent rights. If any such proposals are adopted, our business and results of operations could be adversely affected. Also in the U.S., in addition to the process for challenging patents set forth in the BPCIA, which applies to biological products, the Hatch-Waxman Act provides generic companies substantial incentives to seek to invalidate our patents covering small molecule pharmaceutical products. As a result, we expect that our U.S. patents on major pharmaceutical products, including biologics, will continue to be routinely challenged in litigation and may not be upheld. In addition, a separate IPR process currently allows competitors to seek invalidation of patents at the USPTO without the protections of the BPCIA or Hatch-Waxman Act. The use of IPR proceedings after the institution of litigation pursuant to the BPCIA or Hatch-Waxman Act is currently a topic of debate among legislators and the future ability of our competitors to use IPR proceedings as an alternative to Hatch-Waxman Act or BPCIA litigation procedures to challenge our patents remains uncertain. The USPTO issued an interim procedure regarding the use of discretionary denials of IPR proceedings when there is parallel district court litigation. However, it is not clear how this interim procedure could affect the ability of our competitors to institute IPR proceedings after institution of litigation. If our patents are challenged through this expedited review process, even if we prevail in demonstrating the validity of our patent, our win may not preclude future challenges at the PTAB and is not binding on federal district courts, meaning the same patent can be challenged by other competitors. We face many generic manufacturer challenges to our patents outside the U.S. as well. The entry of generic competitors typically results in rapid and severe declines in revenues. In addition, competitors or other third parties may claim that our activities infringe patents or other intellectual property rights held by them. If successful, such claims could result in our being unable to market a product in a particular territory or being required to pay significant damages for past infringement or royalties on future sales. In addition, intellectual property protection in certain jurisdictions is weak and we face heightened risks to our intellectual property rights in these jurisdictions, including competition with generic or counterfeit versions of our products at or relatively shortly after launch. See Item 1, "Business - Patents, Trademarks, and Other Intellectual Property Rights" and Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies," for more details. 29 29 29 **Current (2026):** Our long-term success depends on our ability to continually discover or acquire, develop, and commercialize innovative medicines.

The USPTO issued procedures regarding the discretionary denial by the Director of institution of IPR proceedings based on the agency's workload and priorities. The USPTO's ability to apply these 30 30 30 procedures is being challenged, and it is not clear how these procedures will affect the ability of our competitors to institute IPR proceedings. If our patents are challenged through this expedited review process, even if we prevail in demonstrating the validity of our patent, our win may not preclude future challenges at the Patent Trial and Appeal Board and would not be binding on federal district courts, meaning the same patent can be challenged by other competitors. We face many generic manufacturer challenges to our patents outside the U.S. as well. The entry of generic competitors typically results in rapid and severe declines in revenues. In addition, competitors or other third parties may claim that our activities infringe patents or other intellectual property rights held by them. If successful, such claims could result in our being unable to market a product in a particular territory or require payment of significant damages for past infringement or royalties on future sales. Intellectual property threats across international markets include policies which favor domestic competitors or are otherwise disadvantageous to our products, challenges to our patents' validity in foreign courts, and government policies that force technology transfer or undermine or nullify patent protections under the guise of health emergencies or other public interests. Furthermore, intellectual property protection in certain jurisdictions is weak and we face heightened risks to our intellectual property rights in these jurisdictions, including competition with generic or counterfeit versions of our products at or relatively shortly after launch as well as the risk of diversion of generic or counterfeit products from these jurisdictions into others. See Item 1, "Business - Patents, Trademarks, and Other Intellectual Property Rights," and Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies," for more details. --- ## Modified Risk: Reliance on third-party relationships and outsourcing arrangements could adversely affect our business. **Key changes:** - Updated: "We rely on third parties, including suppliers, distributors, alliances and collaborations with other pharmaceutical and biotechnology companies, and third-party service providers, for selected aspects of product and clinical development, manufacturing, commercialization, hosting of and support for IT systems, product distribution, and certain financial transactional processes." - Updated: "officials have enacted and continue to consider legislation or other actions that are intended to limit supply chain reliance on China, including the BIOSECURE Act." - Updated: "Failure of third parties to meet their contractual, regulatory, confidentiality, privacy, security, or other obligations to us, our clinical trial subjects, and patients could have a material adverse effect on our business and could also result in non-compliance with legal or regulatory requirements or industry standards or subject us to reputational harm." **Prior (2025):** We rely on third parties, including suppliers, distributors, alliances, and collaborations with other pharmaceutical and biotechnology companies, and third-party service providers, for selected aspects of product and clinical development, manufacturing, commercialization, hosting of, and support for, IT systems, product distribution, and certain financial transactional processes. As examples, we outsource the day-to-day management and oversight of some of our clinical trials to contract research organizations, certain active ingredient manufacturing, finishing operations, and device or component production and assembly to contract manufacturing organizations, and the distribution of our products through logistics providers. To support anticipated demand for our current and prospective products, we have expanded relationships with contract manufacturing organizations and other third parties in recent periods. 32 32 32 Outsourcing involves many risks, including the risk that third parties may not perform to our standards or legal requirements; may not produce reliable results; may not perform in a timely manner; may not maintain the confidentiality, integrity, and availability of confidential and proprietary information relating to us, our clinical trial subjects, or patients; may experience disruption or fail to perform due to IT system vulnerabilities, such as inadequacies, inadequate controls or procedures, operating failures, unauthorized access, service interruptions or failures, security breaches, malicious intrusions, theft, exfiltration, ransomware or other cyber-attacks; may be unable to satisfy their commitments to us in which case we may not be able to achieve acceptable alternative sourcing; or may fail to perform at all. The foregoing risks may be heightened in jurisdictions outside the U.S., where we may have fewer alternative providers as well as face additional costs, uncertainties, and risks. Among other third-party providers, we, and the pharmaceutical industry generally, depend on China-based suppliers for portions of our supply chain. U.S. officials are increasingly considering legislation or other actions that are intended to limit supply chain reliance on China, including the BIOSECURE Act. In February 2025, the U.S. presidential administration imposed new tariffs on Chinese goods and China responded with tariffs on select U.S. goods. If enacted, additional measures could result in supply disruptions or delays, increase costs more significantly, or invite further retaliatory measures, any of which could negatively impact our business. See, Item 1A, "Risk Factors - Risks Related to Doing Business Internationally - Uneven economic growth or downturns or international trade and other global disruptions, geopolitical tensions, or disputes could adversely affect our business and operating results" for additional information. In some cases, product or indication approvals depend on the outcome of regulatory inspections of third parties on which we rely. Third-party inspection outcomes have and may in the future delay or prevent product launches and otherwise negatively affect our business. Failure of third parties to meet their contractual, regulatory, confidentiality, privacy, security, or other obligations to us, our clinical trial subjects, and our patients could have a material adverse effect on our business and could also result in non-compliance with legal or regulatory requirements or industry standards or subject us to reputational harm. **Current (2026):** We rely on third parties, including suppliers, distributors, alliances and collaborations with other pharmaceutical and biotechnology companies, and third-party service providers, for selected aspects of product and clinical development, manufacturing, commercialization, hosting of and support for IT systems, product distribution, and certain financial transactional processes. As examples, we outsource the day-to-day management and oversight of some of our clinical trials to contract research organizations, some product testing to contract laboratories, certain active ingredient manufacturing, finishing operations, device or component production and assembly, and packaging to contract manufacturing organizations, and the distribution of our products through logistics providers. To support anticipated demand for our current and prospective products and further other business initiatives, we have expanded relationships with contract manufacturing organizations, entities supporting consumer directed access channels, artificial intelligence vendors, and other third parties in recent periods. Outsourcing involves many risks, including the risk that third parties may not perform to our standards or legal requirements; may not produce reliable results; may not perform in a timely manner; may misuse or not maintain the confidentiality, integrity, and availability of confidential and proprietary information relating to us, our clinical trial subjects, or patients; may experience disruption or fail to perform due to IT system vulnerabilities, such as inadequacies, inadequate controls or procedures, operating failures, unauthorized access, service interruptions or failures, security breaches, malicious intrusions, fraud, theft, exfiltration, ransomware or other cyber-attacks; may be unable to satisfy their commitments to us in which case we may not be able to achieve acceptable alternative sourcing; or may fail to perform at all.

Among other third-party providers, we, and the pharmaceutical industry generally, depend on China-based suppliers for portions of our supply chain. U.S. officials have enacted and continue to consider legislation or other actions that are intended to limit supply chain reliance on China, including the BIOSECURE Act. In addition, historically, geopolitical tensions between the U.S. and China have led to the imposition of tariffs, sanctions, and certain other business restrictions between the U.S. and China. In 2025, the U.S. government imposed new tariffs on Chinese goods and China responded with tariffs on select U.S. goods. Tariffs have been imposed or proposed on a variety of other geographies in which we have third-party suppliers. If enacted, additional measures could result in supply disruptions or delays, increase costs more significantly, or invite further retaliatory measures, any of which could negatively impact our business and results of operations. See Item 1A, "Risk Factors - Risks Related to Doing Business Internationally - Our global operations subject us to risks, including as related to uneven economic growth or downturns, international trade, and other global disruptions, geopolitical tensions, or disputes" for additional information. In some cases, product or indication approvals depend on the outcome of regulatory inspections of third parties on which we rely. Third-party inspection outcomes have and may in the future delay or prevent product launches and otherwise negatively affect our business. Failure of third parties to meet their contractual, regulatory, confidentiality, privacy, security, or other obligations to us, our clinical trial subjects, and patients could have a material adverse effect on our business and could also result in non-compliance with legal or regulatory requirements or industry standards or subject us to reputational harm. --- ## Modified Risk: We are subject to evolving and complex tax laws, which may result in additional liabilities. **Key changes:** - Added: "Inherent uncertainties exist in estimates of many tax positions due to the complexity of tax laws." - Added: "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 in our estimates for uncertain tax positions and could affect our results of operations in any given period." **Prior (2025):** We are subject to income taxes in the U.S. and numerous other jurisdictions, and in the course of our business, we make judgments about the expected tax treatment of various transactions and events. Changes in tax laws, regulations, administrative practices, principles, disclosure obligations, and interpretations, as well as events that differ from our expectations, have affected and may adversely affect our effective tax rates, cash flows, and/or results of operations. In addition, 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 and examinations of cross-border tax issues, which could unfavorably impact our results of operations and cash flows. Further, actions taken with respect to tax-related matters by associations such as the Organisation for Economic Co-operation and Development (OECD) and the European Commission could influence tax laws in countries in which we operate, such as the enactments by both EU and non-EU countries of a global minimum tax. Modifications to key elements of the U.S. or international tax framework could have a significant impact on our effective tax rate, results of operations, and cash flows. See Item 7, "Management's Discussion and Analysis - Executive Overview - Other Matters - Tax Matters" and Item 8, "Financial Statements and Supplementary Data - Note 14: Income Taxes," for more details. **Current (2026):** We are subject to income taxes in the U.S. and numerous other jurisdictions, and in the course of our business, we make judgments about the expected tax treatment of various transactions and events.

In addition, 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 and examinations of cross-border tax issues, which could unfavorably impact our results of operations and cash flows. 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 in our estimates for uncertain tax positions and could affect our results of operations in any given period. Further, actions taken with respect to tax-related matters by associations such as the Organisation for Economic Co-operation and Development (OECD) and the European Commission could influence tax laws in countries in which we operate, such as the enactments by both EU and non-EU countries of a global minimum tax.

See Item 7, "Management's Discussion and Analysis - Executive Overview - Other Matters - Tax Matters" and Item 8, "Financial Statements and Supplementary Data - Note 14: Income Taxes," for more details. --- ## Modified Risk: We derive a significant percentage of our total revenue from relatively few products and sell our products through consolidated supply chain entities, which subjects us to various risks. **Key changes:** - Updated: "We derived direct product and/or collaboration and other revenues of more than $3 billion for each of Mounjaro, Zepbound, Verzenio, Trulicity, Taltz, and Jardiance (including Glyxambi, Synjardy, and Trijardy XR) that collectively accounted for 82 percent of our total revenues in 2025." - Updated: "If one of these significant wholesalers encounters financial or other difficulties or otherwise is unable or unwilling to support distribution of our products, it could cause disruption to our supply chain or we might be unable to timely collect the amounts that the wholesaler owes us, which could negatively impact our results of operations." - Updated: "retail pharmacies due to pharmacy benefit manager reimbursement pressures, among other things, have resulted and may result in financial difficulties for some pharmacies that impact patient experiences, lead to determinations by certain pharmacies to not carry one or more of our significant products or threaten the viability of these pharmacies, which could negatively impact our business and results of operations." - Updated: "policymakers at the federal and state levels who have proposed and enacted legislation or administrative rules, or undertaken enforcement actions intended to address concerns regarding the impact these intermediaries have on drug pricing and patients' out of pocket costs." **Prior (2025):** We derived direct product and/or collaboration and other revenues of more than $3 billion for each of Mounjaro, Verzenio, Trulicity, Zepbound, Jardiance (including Glyxambi, Synjardy, and Trijardy XR), and Taltz that collectively accounted for 75 percent of our total revenues in 2024. In particular, Mounjaro, Trulicity, and Zepbound accounted for 48 percent of our total revenues in 2024 and we expect cardiometabolic health products to represent a significant and growing portion of our business, revenues, and prospects. Loss of patent protection, changes in prescription rates, material product liability or pricing litigation, unexpected side effects or safety concerns, significant changes or fluctuations in demand, regulatory proceedings and investigations, negative publicity affecting doctor or patient confidence, pressure from existing or new competitive products, pipeline developments by us or our competitors, counterfeit and illegally compounded drugs, changes in labeling, pricing, and insufficient access, or reimbursement, or actual or perceived supply shortages or disruptions for these products or any of our other major products could materially impact our results of operations or result in significant and sudden declines or volatility in the trading price of our common stock and market capitalization. In addition, in the U.S., most of our products are distributed through a limited number of wholesalers. If one of these significant wholesalers encounters financial or other difficulties or otherwise is unable to support distribution of our products, it could cause disruption to our supply chain or we might be unable to timely collect the amounts that the wholesaler owes us, which could negatively impact our results of operations. See Item 1, "Business - Marketing and Distribution," for more details. Challenges to U.S. retail pharmacies due to pharmacy benefit manager reimbursement pressures, among other things, have resulted in financial difficulties for some pharmacies that may impact patient experiences, lead to determinations by certain pharmacies to not carry one or more of our significant products or threaten the viability of these pharmacies, which could negatively impact our business and results of operations. 27 27 27 Moreover, the negotiating power of health plans, managed care organizations, pharmacy benefit managers, and other supply chain entities has increased due to consolidation, regulatory, and other market impacts, and they, along with governments, increasingly employ formularies to control costs and encourage utilization of certain drugs, including through the use of formulary inclusion, or favorable formulary placement. Such stakeholders have also increasingly imposed utilization management tools to limit access to our products. As these practices expand, including due to potential further consolidation of U.S. private third-party payers, we may face difficulty in obtaining or maintaining timely or adequate pricing or formulary placement of our products. We expect that consolidation of supply chain entities will continue to increase competitive and pricing pressures on pharmaceutical manufacturers. Pharmacy benefit manager practices have come under increased scrutiny from U.S. policymakers at the federal and state level who have proposed legislation intended to address concerns regarding the impact that these intermediaries have on drug pricing and patients' out of pocket costs. If promulgated, such legislation could have resultant implications, costs, or consequences for our business and how we interact with these entities. For additional information on pricing and reimbursement for our pharmaceutical products, see Item 1, "Business - U.S. Private Sector Dynamics" and "Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access - U.S." **Current (2026):** We derived direct product and/or collaboration and other revenues of more than $3 billion for each of Mounjaro, Zepbound, Verzenio, Trulicity, Taltz, and Jardiance (including Glyxambi, Synjardy, and Trijardy XR) that collectively accounted for 82 percent of our total revenues in 2025. In particular, 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. Factors such as loss of patent protection, changes in prescription rates, material product liability or pricing claims or litigation, unexpected side effects or safety concerns, significant changes or fluctuations in demand, channel dynamics, regulatory proceedings and investigations, negative publicity affecting doctor or patient confidence, pressure from existing or new competitive products, pipeline developments by us or our competitors, counterfeit and illegally compounded drugs, changes in labeling, pricing, and insufficient access, or reimbursement, or actual or perceived supply shortages, imbalances, or disruptions for these products or any of our other major products could materially impact our results of operations or result in significant and sudden declines or volatility in the trading price of our common stock and market capitalization. In addition, in the U.S., most of our products are distributed through a limited number of wholesalers. If one of these significant wholesalers encounters financial or other difficulties or otherwise is unable or unwilling to support distribution of our products, it could cause disruption to our supply chain or we might be unable to timely collect the amounts that the wholesaler owes us, which could negatively impact our results of operations. See Item 1, "Business - Marketing and Distribution," for more details. Challenges to U.S. retail pharmacies due to pharmacy benefit manager reimbursement pressures, among other things, have resulted and may result in financial difficulties for some pharmacies that impact patient experiences, lead to determinations by certain pharmacies to not carry one or more of our significant products or threaten the viability of these pharmacies, which could negatively impact our business and results of operations. Moreover, the negotiating power of health plans, managed care organizations, pharmacy benefit managers, and other supply chain entities has increased, and they, along with governments, employ formularies and other methods to control costs and encourage utilization of certain drugs, including through the use of formulary inclusion or favorable formulary placement. Such stakeholders have also increasingly imposed utilization management and other tools to limit access to our products. These practices in some cases create difficulty in obtaining or maintaining timely or adequate pricing or formulary placement of our products. For example, in July 2025, CVS Caremark, the pharmacy benefit management division of CVS Health, stopped covering Zepbound as a preferred obesity management medicine on some insurance plans, which has negatively impacted access for patients covered under these plans. We expect supply chain entities will continue to exert competitive and pricing pressures on pharmaceutical manufacturers. Pharmacy benefit manager practices have come under increased scrutiny from U.S. policymakers at the federal and state levels who have proposed and enacted legislation or administrative rules, or undertaken enforcement actions intended to address concerns regarding the impact these intermediaries have on drug pricing and patients' out of pocket costs. Such legislation, rules, or enforcement could have implications, costs, or consequences for our business and how we interact with these entities. For additional information on pricing and reimbursement for our pharmaceutical products, see Item 1, "Business - U.S. Private Sector Dynamics" and "Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access - U.S." --- ## Modified Risk: Manufacturing, quality, or supply chain difficulties, disruptions, or shortages could lead to product supply problems or other negative outcomes. **Key changes:** - Updated: "We are continuing the significant expansion of our manufacturing capabilities and substantial investment in long-term supply agreements to fortify our supply and support our ability to meet anticipated demand for our products." - Updated: "Supply chain difficulties, disruptions or shortages may arise from our or contracted supply chain activity as well as from external environmental factors." - Updated: "Challenges and disruptions may include (i) actual or perceived quality, oversight, or regulatory compliance problems; (ii) equipment, mechanical, data, or IT system vulnerabilities, such as system inadequacies, inadequate controls or procedures, operating failures, unauthorized access, service interruptions or failures, security breaches, malicious intrusions, theft, exfiltration, ransomware or other cyber-attacks from a variety of sources; (iii) labor deficiencies; (iv) inability to obtain single-source or other raw or intermediate materials; or (v) issues related to contractors and suppliers, including the failure, inability, or refusal of a supplier or contract manufacturer to supply contracted quantities in a timely or compliant manner or at all, increases in demand on a supplier with constrained capacity, contractual disputes with our suppliers and contract manufacturers, and vertical integration by competitors within our supply chain." - Updated: "Finding alternative suppliers if and as necessary due to geopolitical developments or otherwise may not be feasible or could require significant time and expense due to the nature of our products and the need to obtain regulatory approvals, which would cause disruptions to patients and detrimentally impact our business." - Updated: "Conversely, overestimation of demand or events that limit demand for our products or anticipated demand for product candidates would undermine our ability to realize the full benefit of significant capital expenditures that we have incurred, and expect to continue to incur, to augment manufacturing capacity, may render built or in process manufacturing capacity unnecessary, may result in supply imbalances, or may subject us to contractual payment obligations, which may be significant." **Prior (2025):** We are continuing the significant expansion of our manufacturing capabilities and substantial investment in long-term supply agreements to fortify supply and support anticipated demand for our products. Pharmaceutical manufacturing is complex and highly regulated. Manufacturing or quality assurance difficulties at our facilities or those of our contractors and suppliers, the failure or refusal of a supplier or contract manufacturer to supply contracted quantities in a timely manner or at all, or increases in demand on a supplier with constrained capacity have resulted and may in the future result in delays and disruptions in the manufacturing, distribution, and sale of our products and/or product shortages, leading to lost revenue, reduced market opportunities, and the possibility of additional market entrants. In select cases, supply constraints may also lead to pauses, discontinuations, or other product availability issues in one or more markets, which could have a material adverse effect on our consolidated results of operations, cash flows, and reputation. Further, cost inflation and global transportation and logistics 31 31 31 challenges, as well as tight labor markets, have caused, and in the future may cause, delays in, and/or increase costs related to, distribution of our medicines, the construction or other acquisition of additional manufacturing capacity, procurement activity, and supplier or contract manufacturer arrangements. These disruptions and challenges could result from actual or perceived quality, oversight, or regulatory compliance problems; natural disasters (including increased instances or severity of natural disasters or other events that may be due to climate change), public health outbreaks, epidemics, or pandemics; periods of uneven economic growth or downturns; emergence or escalation of, and responses to international tension and conflicts; equipment, mechanical, data, or IT system vulnerabilities, such as system inadequacies, inadequate controls or procedures, operating failures, unauthorized access, service interruptions or failures, security breaches, malicious intrusions, theft, exfiltration, ransomware or other cyber-attacks from a variety of sources; labor shortages; challenges and complexities in manufacturing new drug modalities; contractual disputes with our suppliers and contract manufacturers; vertical integration by competitors within our supply chain; or inability to obtain single-source or other raw or intermediate materials. Regional or single source dependencies may in some cases accentuate risks related to manufacturing and supply. For example, we, and the pharmaceutical industry generally, depend on China-based suppliers for portions of our supply chain, including integral chemical synthesis, reagents, starting materials, and ingredients. Finding alternative suppliers if and as necessary due to geopolitical developments or otherwise may not be feasible or could take a significant amount of time and involve significant expense due to the nature of our products and the need to obtain regulatory approvals which would cause disruptions to patients and detrimentally impact our business. See, Item 1A, "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 Doing Business Internationally - Uneven economic growth or downturns or international trade and other global disruptions, geopolitical tensions, or disputes could adversely affect our business and operating results" for more details. Supply and channel dynamics in some cases also contribute to variability in financial results for our products from period to period. Difficulties in predicting or variability in demand and supply for our products and those of our competitors and the very long lead times necessary for the expansion and regulatory qualification of pharmaceutical manufacturing capacity have resulted, and in the future may result, in difficulty meeting demand, or disruptions, shortages, and higher costs in the supply of, our products. For example, at various times during 2024 demand for our incretin medicines exceeded production. While tirzepatide supply currently exceeds demand in the U.S., demand remains dynamic and could be impacted by a variety of factors. Supply considerations will continue to influence the timing and approach (including available presentations) of tirzepatide launches in new markets. Despite our ongoing efforts to meet projected future demand by obtaining additional internal and contracted manufacturing capacity, there can be no assurances that such capacity increases that we expect will be needed to meet future demand will be realized as expected or that we will meet demand in launched markets in the future. Delays or challenges in operationalizing additional manufacturing capacity could limit our ability to capitalize on demand for our products. Conversely, unexpected events that limit demand for our products or anticipated demand for product candidates would undermine our ability to realize the full benefit of significant capital expenditures that we have incurred, and expect to continue to incur, to augment manufacturing capacity, may render built or in process manufacturing capacity unnecessary, and may also subject us to contractual payment obligations, which may be significant. The foregoing risks and uncertainties could negatively impact our consolidated results of operations and reputation. See Item 1, "Business - Raw Materials and Product Supply" and Item 7, "Management's Discussion and Analysis - Financial Condition and Liquidity," for more details. **Current (2026):** We are continuing the significant expansion of our manufacturing capabilities and substantial investment in long-term supply agreements to fortify our supply and support our ability to meet anticipated demand for our products. Pharmaceutical manufacturing is complex and highly regulated. Supply chain difficulties, disruptions or shortages may arise from our or contracted supply chain activity as well as from external environmental factors. Variability in demand and supply for our products can also challenge supply capacity and resiliency. Supply and channel dynamics in some cases contribute to variability in financial results for our products from period to period. Difficulties related to supply chain activities have resulted and may in the future result in delays and disruptions in the manufacturing, distribution, and sale of our products and/or product shortages, leading to lost revenue, increased costs, reduced market opportunities, and the possibility of additional market entrants. In select cases, supply constraints may also lead to pauses, discontinuations, or other product availability issues in one or more markets, which could have a material adverse effect on our consolidated results of operations, cash flows, and reputation. Challenges and disruptions may include (i) actual or perceived quality, oversight, or regulatory compliance problems; (ii) equipment, mechanical, data, or IT system vulnerabilities, such as system inadequacies, inadequate controls or procedures, operating failures, unauthorized access, service interruptions or failures, security breaches, malicious intrusions, theft, exfiltration, ransomware or other cyber-attacks from a variety of sources; (iii) labor deficiencies; (iv) inability to obtain single-source or other raw or intermediate materials; or (v) issues related to contractors and suppliers, including the failure, inability, or refusal of a supplier or contract manufacturer to supply contracted quantities in a timely or compliant manner or at all, increases in demand on a supplier with constrained capacity, contractual disputes with our suppliers and contract manufacturers, and vertical integration by competitors within our supply chain. Regional or single-source dependencies may in some cases accentuate risks and costs (e.g., tariffs) related to manufacturing and supply. For example, we, and the pharmaceutical industry generally, depend on China-based suppliers for portions of our supply chain, including integral chemical synthesis, reagents, starting materials, and ingredients. Finding alternative suppliers if and as necessary due to geopolitical developments or otherwise may not be feasible or could require significant time and expense due to the nature of our products and the need to obtain regulatory approvals, which would cause disruptions to patients and detrimentally impact our business. See, Item 1A, "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 Doing Business Internationally - Our global operations subject us to risks, including as related to uneven economic growth or downturns, international trade, and other global disruptions, geopolitical tensions, or disputes" for more details. External environmental factors have also caused, and in the future may cause, delays in, and/or increase costs related to, distribution of our medicines, the construction or other acquisition of additional manufacturing capacity, procurement activity, and supplier or contract manufacturer arrangements. Relevant external environmental factors include (i) tariffs, (ii) cost inflation and global transportation and logistics challenges; (iii) labor market dynamics; (iv) natural disasters (including increased instances or severity of natural disasters or other events that may be due to climate change); (v) public health outbreaks, epidemics, or pandemics; (vi) periods of uneven economic growth or downturns; and (vii) the emergence or escalation of, or responses to international tension and conflicts. Difficulties in predicting or variability in demand and supply for our products and those of our competitors and the very long lead times necessary for the expansion and regulatory qualification of pharmaceutical manufacturing capacity have resulted, and in the future may result, in difficulty meeting demand, causing disruptions, shortages, or higher costs in the supply of our products. Despite our ongoing efforts to meet projected worldwide demand for our products by obtaining additional internal and contracted manufacturing capacity, there can be no assurances that such capacity increases that we expect will be needed to meet 33 33 33 future demand will be realized as expected or that we will meet demand in launched markets in the future. Delays or challenges in operationalizing additional manufacturing capacity could limit our ability to capitalize on demand for our products. Conversely, overestimation of demand or events that limit demand for our products or anticipated demand for product candidates would undermine our ability to realize the full benefit of significant capital expenditures that we have incurred, and expect to continue to incur, to augment manufacturing capacity, may render built or in process manufacturing capacity unnecessary, may result in supply imbalances, or may subject us to contractual payment obligations, which may be significant. The foregoing risks and uncertainties could negatively impact our consolidated results of operations and reputation. See Item 1, "Business - Raw Materials and Product Supply," and Item 7, "Management's Discussion and Analysis - Financial Condition and Liquidity," for more details. --- ## Modified Risk: We and our products face intense competition, and such competition could have a material adverse effect on our business. **Key changes:** - Updated: "We compete with a large number of multinational pharmaceutical companies, biotechnology companies, and generic pharmaceutical companies and face intensifying competition worldwide, including from China and other markets where research and development capabilities have expanded and accelerated significantly." - Added: "Technological innovation has amplified and we expect will continue to amplify competitive aspects of our business, including by enabling additional participation in and breadth of drug discovery and new healthcare delivery models." - Added: "Business practices or commercial capabilities that we deploy in light of these or other market dynamics may not prove sufficient." - Updated: "Particularly for biosimilars, health authority guidelines and legislative actions could continue to make it less burdensome for competitor products to enter the market and further incentivize uptake of biosimilars." - Updated: "26 26 26 Our success depends on a market that is observant of intellectual property rights and regulatory requirements." **Prior (2025):** We compete with a large number of multinational pharmaceutical companies, biotechnology companies, and generic pharmaceutical companies and, in many cases, our products compete against the leading products of one or more of our competitors. To compete successfully, we must continue to deliver innovative, cost-effective products through internal innovation or business development that meet important medical needs, provide improved outcomes and a positive consumer experience for patients, and deliver value to payers. Our product revenues and prospects are adversely affected by patient access issues, the introduction by competitors of branded products that are first to market, have better marketplace access, have greater brand recognition or are perceived as superior by the marketplace, by generic or biosimilar versions of our branded products, and by generic or biosimilar versions of other products in the same therapeutic class as our branded products. Our revenues are also adversely affected by treatment innovations, including new or superior modalities, that eliminate or minimize the need for treatment with our existing products, and our existing products could be subject to decreased sales volumes, realized price reductions, or both. In some cases, the introduction of our own innovative products results in these adverse impacts for our preexisting products. Regulation of generic and biosimilar products varies around the world and such regulation is complex and subject to ongoing interpretation and implementation by regulatory agencies and courts. Particularly for biosimilars, health authority guidelines and legislative actions could make it less burdensome for competitor products to enter the market and further incentivize uptake of biosimilars. Given the importance to us of marketed biologic products and those in our clinical-stage pipeline, such regulation could have a material adverse effect on our business. See Item 1, "Business - Competition" and "Business - Research and Development," for more details. Alternatively, actual or perceived failure of robust generic and biosimilar competition could propel governments to adopt additional policies and legislation that threaten our intellectual property, pricing of our products, or other aspects of our business. Our success depends on a market that is observant of intellectual property rights and regulatory requirements. Developments that undermine that landscape can significantly impact our business and reputation. For example, we have seen an increase in the production, marketing, and sale of counterfeit, misbranded, adulterated, and compounded incretins that could materially impact us. Our actions intended to stop or prevent illegal sales of such medicines may be costly or ineffective. See Item 1, "Business - Government Regulation of Our Operations and Products," for additional information on market risks related to counterfeit, misbranded, adulterated, and compounded medicines. If inadequately regulated, e- 25 25 25 commerce may increase the prevalence of dangerous counterfeit or diverted products and scams, potentially exposing patients to significant risks. Our reputation and business could suffer harm as a result of counterfeit or diverted drugs sold under our brand name, which may also impact our business and financial results. In addition, we rely on our ability to attract, engage, and retain highly qualified and skilled scientific, technical, management, and other personnel in order to compete effectively. To continue to commercialize our products, and advance the research, development, and commercialization of additional modalities, indications, and product candidates, we have expanded, and will likely need to further expand, our workforce, both in and outside the U.S. We continue to face intense competition for qualified individuals from numerous multinational pharmaceutical companies, biotechnology companies, academic and other research institutions, as well as employers near our manufacturing and other facilities, which has and may continue to increase our labor costs. Our failure to compete effectively for talent could negatively affect sales of our current and any future approved products and indications, and could result in material financial, legal, commercial, or reputational harm to our business. **Current (2026):** We compete with a large number of multinational pharmaceutical companies, biotechnology companies, and generic pharmaceutical companies and face intensifying competition worldwide, including from China and other markets where research and development capabilities have expanded and accelerated significantly. In many cases, our products compete against the leading products of one or more of our competitors. To compete successfully in a highly competitive and increasingly fast-paced global environment, we must deliver innovative, cost-effective products through internal innovation or business development that meet important medical needs, provide improved outcomes and a positive consumer experience for patients, and deliver value to payers. Our product revenues and prospects are adversely affected by patient access issues, the introduction by competitors of branded products that are first to market, have better marketplace access, have greater brand recognition, or are perceived as superior by the marketplace, by price competition, by generic or biosimilar versions of our branded products, and by generic or biosimilar versions of other products in the same therapeutic class as our branded products. Our revenues are also adversely affected by treatment innovations, including new or superior modalities, that eliminate or minimize the need for treatment with our existing products, and our existing products could be subject to decreased sales volumes, realized price reductions, or both. In some cases, the introduction of our own innovative products results in these adverse impacts for our preexisting products. Technological innovation has amplified and we expect will continue to amplify competitive aspects of our business, including by enabling additional participation in and breadth of drug discovery and new healthcare delivery models. Business practices or commercial capabilities that we deploy in light of these or other market dynamics may not prove sufficient. Regulation of generic and biosimilar products varies around the world and such regulation is complex and subject to ongoing interpretation and implementation by regulatory agencies and courts. Particularly for biosimilars, health authority guidelines and legislative actions could continue to make it less burdensome for competitor products to enter the market and further incentivize uptake of biosimilars. Given the importance to us of marketed biologic products and those in our clinical-stage pipeline, such regulation could have a material adverse effect on our business. See Item 1, "Business - Competition" and "Business - Research and Development," for more details. Alternatively, actual or perceived failure of robust generic and biosimilar competition could propel governments to adopt additional policies and legislation that threaten our intellectual property, pricing of our products, or other aspects of our business. 26 26 26 Our success depends on a market that is observant of intellectual property rights and regulatory requirements. Developments that undermine that landscape can significantly impact our business and reputation. For example, we continue to see the production, marketing, and sale of counterfeit, misbranded, adulterated, and mass-compounded incretins in the U.S. and other markets that could materially impact us. In addition to patient safety concerns, improper commercialization and dispensation practices by these actors may inappropriately condition consumer expectations or otherwise disadvantage compliant market participants. Our actions intended to stop or prevent illegal sales of such medicines are costly and may be ineffective. See Item 1, "Business - Government Regulation of Our Operations and Products," for additional information on market risks related to counterfeit, misbranded, adulterated, and mass-compounded medicines. If inadequately regulated, e-commerce may increase the prevalence of dangerous counterfeit or mass-compounded products and scams, potentially exposing patients to significant risks. Our reputation and business could suffer harm as a result of counterfeit or mass-compounded drugs sold under our brand name, which may also impact our business and financial results. In addition, we rely on our ability to attract and retain highly qualified and skilled scientific, technical, management, and other personnel in order to compete effectively. To capitalize on the rapid development of next-generation technologies and otherwise effectively compete, we must continue to enhance skill sets and develop our workforce, both in and outside the U.S. We face intense competition for qualified individuals from numerous multinational companies, academic and other research institutions, as well as employers near our manufacturing and other facilities, which has increased and may continue to increase our labor costs. Our failure to compete effectively for talent could negatively affect our ability to discover, develop, manufacture, and sell our medicines, resulting in material financial, legal, commercial, or reputational harm to our business. --- ## Modified Risk: Our business is subject to government price controls and other public and private restrictions on pricing, reimbursement, and access for our drugs, which could have a material adverse effect on our results of operations, reputation, or business. **Key changes:** - Updated: "Public and private actors continue to take aggressive steps to control expenditures for pharmaceuticals by placing restrictions on pricing and reimbursement for, and patient access to, our medicines." - Updated: "In November 2025, we announced preliminary voluntary agreements with the U.S." - Updated: "The effect of reducing prices and reimbursement for certain of our products impacts our business and consolidated results of operations." - Updated: "In addition, government price reporting and payment regulations are complex, and require ongoing assessment of the methods by which we calculate and report pricing." - Updated: "For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access," Item 7, "Management's Discussion and Analysis - Executive Overview - Other Matters - Trends Affecting Pharmaceutical Pricing, Reimbursement, and Access and Certain Other Regulatory Developments," and Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies."" **Prior (2025):** Public and private payers continue to take aggressive steps to control their expenditures for pharmaceuticals by placing restrictions on pricing and reimbursement for, and patient access to, our medicines. These pressures have negatively affected, and we expect will continue to negatively affect, our consolidated results of operations. Governments and private payers worldwide have intensified their scrutiny of, and actions intended to address, pricing, reimbursement, and access to pharmaceutical products and are demanding greater commercial and clinical value from pharmaceutical companies in the form of strong product differentiation and demonstrated value. We continue to experience scrutiny on the pricing of current and potential diabetes, obesity, and Alzheimer's disease products due to payer concern over projected growth in these markets and, for certain of these drugs, the anticipated duration of treatment. We have also observed scrutiny of pricing and access disparities across jurisdictions. Additional policies, regulations, legislation, or enforcement, including because of the regulatory priorities of the U.S. executive branch and regulatory authorities worldwide, could adversely impact our business and consolidated results of operations. For example, 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 in Medicare effective in 2026. In August 2024, HHS announced the government-set prices for these first ten medicines with Jardiance subject to a 66% discount compared to the 2023 U.S. calendar year list price for a 30-day supply and discounts for the other nine medicines ranging from approximately 38% to 79% below list price. Given our product portfolio, we expect additional products will be selected in future years, which would have the effect of accelerating revenue erosion. The effect of reducing prices and reimbursement for certain of our products could significantly impact our business and consolidated results of operations. Within the U.S., state level transparency initiatives, importation rules, reporting requirements, and mandated programs, including the establishment of drug affordability boards with the power to set upper payment limits on certain drugs in state-regulated plans, have also increased administrative costs, in some cases, compromised confidential business practices and otherwise detrimentally impacted our business. Certain states have also undertaken efforts to codify 340B contract pharmacies into statute or impose other state law mandates, which increase the cost of 340B programs. To date, several states have passed contract pharmacy legislation, which have been subject to various legal challenges. For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access." Further, restrictive or unfavorable pricing, coverage, or reimbursement determinations for our medicines or product candidates by governments, regulatory agencies, courts, or private payers, including in relation to the implementation of the IRA, reference pricing, and compulsory licensing, may adversely impact our business and financial results. We continue to experience additional pricing pressures, rebates, clawbacks, and other changes in reimbursement policies and programs resulting from periods of uneven economic growth or downturns or uncertainty, and the emergence or escalation of, and responses to, international tension and conflicts. 26 26 26 In addition, government price reporting and payment regulations are complex, and require ongoing assessment of the methods by which we calculate and report pricing. Calculation methodologies are inherently subjective and are subject to review and challenge by government agencies. If agencies disagree with our calculations, or the methodologies and assumptions underlying them, we may need to restate previously reported data and could be subject to financial and legal liability, which may be significant. In addition, changes to calculation methodologies could adversely affect our financial position or consolidated results of operations in any given period. For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access," Item 7, "Management's Discussion and Analysis - Executive Overview - Other Matters - Trends Affecting Pharmaceutical Pricing, Reimbursement, and Access and Certain Other Regulatory Developments" and Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies." **Current (2026):** Public and private actors continue to take aggressive steps to control expenditures for pharmaceuticals by placing restrictions on pricing and reimbursement for, and patient access to, our medicines. These pressures have negatively affected and we expect will continue to negatively affect our consolidated results of operations. Governments and private actors worldwide are demanding greater commercial and clinical value from pharmaceutical companies in the form of strong product differentiation and demonstrated value. We continue to experience scrutiny on the pricing of current and potential products due to, among other factors, payer concern over projected growth in demand and, for certain of these drugs, the anticipated duration of treatment. We have also observed scrutiny of pricing and access disparities across jurisdictions. In November 2025, we announced preliminary voluntary agreements with the U.S. government in which, among other arrangements, we agreed to implement measures 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. In general, securing and growing access for our obesity medicines is an important factor in the success of our business. Among other considerations, payers in various international markets do not currently provide coverage for obesity medicines for weight loss indications, requiring patient self-pay. In addition, patient self-pay sales through LillyDirect represented a growing portion of our business in 2025, and we have launched, and continue to explore, new partnerships and tools, including through LillyDirect, to further expand access to our medicines. Our financial results and prospects are subject to risks related to the level and pace of patient participation in cash-pay markets, which may be influenced by pricing, economic conditions, and competitive offerings, as well as regulatory or other actions that could restrict our ability to benefit from such markets, and uncertainty regarding our ability to secure reimbursement coverage in such markets over time. 27 27 27 Additional policies, regulations, legislation, or enforcement, including because of the regulatory priorities of the U.S. executive branch, state attorneys general, and regulatory authorities worldwide, could adversely impact our business and consolidated results of operations. For example, 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 in Medicare (effective beginning in 2026) at a significant discount compared to the list price. 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 additional products will be selected in future years, which would have the effect of accelerating revenue erosion. The effect of reducing prices and reimbursement for certain of our products impacts our business and consolidated results of operations. Within the U.S., state level transparency initiatives, importation rules, reporting requirements, and mandated programs, including the establishment of drug affordability boards with the power to set upper payment limits on certain drugs, have also increased administrative costs, in some cases, compromised confidential business practices and otherwise detrimentally impacted our business. Continued expansion of the 340B program and growth of entities claiming entitlement to 340B pricing, including in ways that may be inconsistent with the statutory scheme and through state laws that purport to mandate 340B sales to contract pharmacies, impact our revenue on an increasing percentage of sales. Changes to the calculation of rebates under the Medicaid program could also increase our Medicaid rebate obligations and decrease the prices charged to 340B covered entities, which could have a significant impact on our business. For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access." Further, restrictive or unfavorable pricing, coverage, or reimbursement determinations for our medicines or product candidates by governments, regulatory agencies, courts, or private actors, including in relation to the IRA, reference pricing, or compulsory licensing, may adversely impact our business and financial results. We continue to experience additional pricing pressures, rebates, clawbacks, and other changes in reimbursement policies and programs resulting from periods of uneven economic growth or downturns or uncertainty, and the emergence or escalation of, and responses to, international tension and conflicts. In addition, government price reporting and payment regulations are complex, and require ongoing assessment of the methods by which we calculate and report pricing. Calculation methodologies are inherently subjective and subject to review and challenge by government agencies and, in some cases, by private actors. If there is disagreement with our calculations, or the methodologies and assumptions underlying them, we may need to restate previously reported data and could be subject to financial and legal liability, which may be significant. In addition, changes to calculation methodologies could adversely affect our financial position or consolidated results of operations in any given period. For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access," Item 7, "Management's Discussion and Analysis - Executive Overview - Other Matters - Trends Affecting Pharmaceutical Pricing, Reimbursement, and Access and Certain Other Regulatory Developments," and Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies." --- ## Modified Risk: We are party to litigation and investigations, which could adversely affect our business. **Key changes:** - Updated: "These claims relate to how we commercialize and/or price our products, product safety, our operations, intellectual property disputes and protection, as well as contractual matters and other disputes." - Updated: "Additionally, government and regulatory authorities have considered and 36 36 36 initiated enforcement or other actions across industries to seek alignment with policy initiatives." **Prior (2025):** We are subject to a substantial number of claims, litigation, and investigations involving various current and historical products and practices. These claims relate to how we commercialize and/or how we price our products, product safety, our operations as well as contractual matters and other disputes. We have also filed lawsuits and taken other legal actions to protect our intellectual property and address unlawful practices. See Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies," for more information on certain matters. Like many companies in our industry, from time to time investigations into aspects of our business include inquiries, subpoenas, and other types of information demands from government and regulatory authorities. There continues to be a significant volume of government and regulatory investigations and litigation against companies operating in our industry, as well as robust regulatory enforcement. Because of the nature of pharmaceutical products, we are, and could in the future become, subject to large numbers of product liability claims for our previous, current, or future products, or to further litigation or investigations, including related to product safety and pricing or other commercial practices. Some of these matters involve numerous plaintiffs and parties seeking large or indeterminate financial claims and may remain unresolved for several years. Such matters could negatively impact our reputation, affect our results of operations or require us to recognize substantial charges to resolve and, if involving marketed products, could adversely affect sales of the product and our consolidated results of operations in any given period. Where we are the plaintiff or complainant, we may be unsuccessful in protecting our intellectual property or mitigating harm to us from unlawful practices. Due to a very restrictive market for liability insurance, we are predominately self-insured for litigation liability losses for all of our products, as well as for litigation or investigations related to our pricing practices or other similar matters. **Current (2026):** We are subject to a substantial number of claims, litigation, and investigations involving various current and historical products and practices. These claims relate to how we commercialize and/or price our products, product safety, our operations, intellectual property disputes and protection, as well as contractual matters and other disputes. We have also filed lawsuits and taken other legal actions to protect our intellectual property and address unlawful practices. See Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies," for more information on certain matters. Like many companies in our industry, from time to time investigations into aspects of our business include inquiries, subpoenas, and other types of information demands from government and regulatory authorities. There continues to be a significant volume of government and regulatory investigations and litigation against companies operating in our industry, as well as robust regulatory enforcement. Additionally, government and regulatory authorities have considered and 36 36 36 initiated enforcement or other actions across industries to seek alignment with policy initiatives. Because of the nature of pharmaceutical products and our evolving business, we are, and could increasingly become, subject to large numbers of product liability claims for our previous, current, or future products, or to further litigation or investigations, including related to product safety, marketing, pricing, or other commercial practices. Some of these matters involve or may involve numerous plaintiffs and parties seeking large or indeterminate financial claims and may remain unresolved for several years. Such matters could negatively impact our reputation, affect our results of operations, or require us to recognize substantial charges to resolve and, if involving marketed products, could adversely affect sales of the product and our consolidated results of operations in any given period. We may also be unsuccessful in protecting our intellectual property or mitigating harm to us from unlawful practices. The ability to insure against such exposures is limited, and due to a very restrictive market for liability insurance we are predominately self-insured for litigation liability losses for all our currently and previously marketed products. --- ## Modified Risk: Our global operations subject us to risks, including as related to uneven economic growth or downturns, international trade, and other global disruptions, geopolitical tensions, or disputes. **Key changes:** - Updated: "Economic slowdowns could lead to decreased utilization of our products globally or in specific markets, affecting our sales." - Updated: "Also, if our customers, suppliers, or collaboration partners experience financial difficulties, we could experience slower customer collections, greater bad debt expense, or performance defaults by suppliers or collaboration partners." - Updated: "Significant portions of our business are conducted in Europe, Asia, and other international geographies." - Updated: "The precise impact of tariffs, trade protection measures, and other restrictions may depend on their ultimate scope, timing, and other factors." - Updated: "For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access." Our arrangements with the U.S." **Prior (2025):** 33 33 33 Economic slowdowns could lead to decreased utilization of our products, affecting our sales. Declining tax revenues and increased government spending on other programs attributable to uneven economic growth or downturns increase the pressure on governments to reduce healthcare spending, leading to increased control of drug prices or lower utilization. Additionally, some customers, including governments or other entities reliant upon government funding and cash-pay patients, may be unable to pay for our products fully or in a timely manner. Also, if our customers, suppliers, or collaboration partners experience financial difficulties, we could experience slower customer collections, greater bad debt expense, and performance defaults by suppliers or collaboration partners. Similarly, uneven economic growth or downturns could limit our ability to access capital markets. In addition, significant portions of our business are conducted in Europe, Asia, and other international geographies. Trade and other global disputes and interruptions, including related to tariffs, trade protection measures, import or export licensing requirements, the imposition of trade sanctions or similar restrictions by the U.S. or other governments, international tension and conflicts, as well as economic stagnation, cost inflation, strains on global transportation, manufacturing, and labor markets, and public health outbreaks, epidemics, or pandemics affect our ability to do business. Among other risks, the use of tariffs and other trade restrictions increase costs and may impact clinical trials or sales of our products, or otherwise complicate aspects of our business. In particular, tensions between the U.S. and China, which have already led to a series of tariffs and sanctions, as well as other business restrictions, could further escalate based on additional trade restrictions or retaliation thereto. In February 2025, the U.S. presidential administration imposed new tariffs on Chinese goods and China responded with tariffs on select U.S. goods. Additionally, tariffs were proposed or threatened with respect to other jurisdictions, including Mexico, Canada and Europe. If geopolitical tensions were to increase and disrupt our operations in, or related to, China or other major international geographies, such disruption would significantly impact our business. See Item 1A, "Risk Factors - Risks Related to Our Operations - Reliance on third-party relationships and outsourcing arrangements could adversely affect our business," for additional information. As a further example, the financial impact of higher energy prices, defense spending, and geopolitical and economic disruptions, has further exacerbated financial pressures on governments with single-payer or government funded healthcare systems, leading to increased impetus for increases in rebates, clawbacks, and other reforms to reimbursement systems, particularly in Europe. These and similar events have adversely affected, and may continue to adversely affect, us, our business partners, and our customers. For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access." In addition to developments related to our business or financial results, or those of our competitors, uneven economic growth, downturns, or other negative global developments, could also undermine our growth or result in significant and sudden declines in the trading price of our common stock and market capitalization. **Current (2026):** Economic slowdowns could lead to decreased utilization of our products globally or in specific markets, affecting our sales. Declining tax revenues and increased government spending on other programs attributable to uneven economic growth or downturns may increase the pressure on governments to reduce healthcare spending, leading to increased control of drug prices or lower utilization. Additionally, some customers, including governments or other entities reliant upon government funding and cash-pay patients, may be unable to pay for our products fully or in a timely manner. Also, if our customers, suppliers, or collaboration partners experience financial difficulties, we could experience slower customer collections, greater bad debt expense, or performance defaults by suppliers or collaboration partners. Similarly, uneven economic growth or downturns could limit our ability to access capital markets. Significant portions of our business are conducted in Europe, Asia, and other international geographies. Our global operations and complex supply chain expose us to legislation and regulatory action in or regarding foreign jurisdictions as well as geopolitical and other cross-border risks. Trade and other global disputes, interruptions, and developments, including those related to tariffs, trade protection measures, import or export licensing requirements or disagreements with authorities regarding tariff classifications, transfer pricing, or valuations, the imposition of trade sanctions or similar restrictions by the U.S. or other governments, international tension and conflicts, as well as economic stagnation, cost inflation, strains on global transportation, manufacturing, and labor markets, and public health outbreaks, epidemics, or pandemics affect our ability to do business and, in some cases, result in financial, operational, legal, business, or reputational harm. Among other risks, the use of tariffs and other trade restrictions may increase costs, impact clinical trials or sales of our products, result in supply disruptions or delays, or otherwise complicate aspects of our business. In 2025, the U.S. and other countries 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. 35 35 35 Moreover, tensions between the U.S. and China, which have already led to a series of tariffs and sanctions, as well as other business restrictions, could further escalate based on additional trade restrictions, retaliation thereto, or otherwise, which could significantly impact our business, including by increasing scrutiny of, or restrictions on, market access, operations, and business development transactions. See Item 1A, "Risk Factors - Risks Related to Our Operations - Reliance on third-party relationships and outsourcing arrangements could adversely affect our business," for additional information. The precise impact of tariffs, trade protection measures, and other restrictions may 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 offset the burden of increased costs from tariffs and related impacts to any meaningful degree. In most international markets, we operate in an environment of government-mandated cost-containment programs. In some markets, including the EU, Japan, and China, governments have significant power as large single payors to regulate prices and access criteria or impose other means of cost control. Geopolitical and economic factors have in various cases exacerbated financial pressures on governments with single-payer or government funded healthcare systems, leading to increases in rebates, clawbacks, and other reforms to reimbursement systems, policies and programs. These and similar events have adversely affected, and may continue to adversely affect, us, our business partners, and our customers. For more details, see Item 1, "Business - Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access." Our arrangements with the U.S. government and broader U.S. policy efforts to align domestic pharmaceutical pricing with international benchmarks may further pressure international payers, and the outcome of competing U.S. and international pricing objectives is uncertain. See Item 1A, "Risk Factors - Risks Related to Our Business and Industry - Our business is subject to government price controls and other public and private restrictions on pricing, reimbursement, and access for our drugs, which could have a material adverse effect on our results of operations, reputation, or business." In addition to developments related to our business or financial results, or those of our competitors, uneven economic growth, downturns, or other negative global developments could undermine our growth or result in significant and sudden declines in the trading price of our common stock and market capitalization. --- *Data sourced from SEC EDGAR.
