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 substantively modified nine risk factors between the 2024 and 2025 10-K filings while maintaining all existing risk categories without additions or removals. The most significant revisions addressed geopolitical and economic disruptions, manufacturing and supply chain vulnerabilities, and litigation exposure related to product pricing and commercialization. These modifications reflect the company's evolving assessment of macro-level business threats and operational challenges rather than a fundamental restructuring of its risk disclosure framework. --- ## Summary | Status | Count | |--------|-------| | New risks added | 0 | | Risks removed | 0 | | Risks modified | 9 | | Unchanged | 7 | --- ## Modified: •Uneven economic growth or downturns or international trade and other global disruptions, geopolitical tensions, or disputes could adversely affect our business and operating results. **Key changes:** - Reworded sentence: "33 33 33 Economic slowdowns could lead to decreased utilization of our products, affecting our sales." - Reworded sentence: "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." **Prior (2024):** 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 cost inflation, strains on global transportation, manufacturing, and labor markets, and public health outbreaks, epidemics, or pandemics, such as the COVID-19 pandemic, affect our ability to do business. For example, tensions between the U.S. and China have led to a series of tariffs and sanctions being imposed by the U.S. on imports from China mainland, as well as other business restrictions. If geopolitical tensions were to increase and disrupt our operations in, or related to, China, such disruption would significantly impact our business. As a further example, the financial impact of higher energy prices, defense spending, and inflation due, in part, to 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 (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. --- ## Modified: •Manufacturing, quality, or supply chain difficulties, disruptions, or shortages could lead to product supply problems. **Key changes:** - Reworded sentence: "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." - Reworded sentence: "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." - Reworded sentence: "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." - Reworded sentence: "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." - Reworded sentence: "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." **Prior (2024):** We are in the midst of a significant expansion of our manufacturing capabilities and substantial investment in long-term supply agreements to support current and 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, or increases in demand on a supplier with constrained capacity could result in delays and disruptions in the manufacturing, distribution, and sale of our products and/or product shortages, leading to lost revenue or reduced marked opportunities. 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 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 partners for 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. Difficulties in predicting or variability in demand 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, we have experienced challenges 31 31 31 in meeting demand for our incretin products in recent periods, partially due to the limited availability of competitor therapies, and expect tight supply to persist while additional manufacturing capacity is operationalized. Despite our ongoing efforts to meet significant expected demand by obtaining additional internal and contracted manufacturing capacity, there can be no assurances that such capacity increases will be realized as expected. Delays or challenges in operationalizing additional manufacturing capacity would limit our ability to capitalize on demand for our products. Conversely, unexpected events that limit demand for our products 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 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 (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.

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. --- ## Modified: •We are party to litigation and investigations related to our products, how we price or commercialize our products, and other aspects of our business, which could adversely affect our business, and we are self-insured for such matters. **Key changes:** - Reworded sentence: "We are subject to a substantial number of claims, litigation, and investigations involving various current and historical products and practices." - Reworded sentence: "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." - Reworded sentence: "Where we are the plaintiff or complainant, we may be unsuccessful in protecting our intellectual property or mitigating harm to us from unlawful practices." **Prior (2024):** We are subject to a substantial number of claims involving various current and historical products, litigation, and investigations. These claims relate to how we commercialize and/or how we price our products, including relating to our 340B drug pricing program, product safety, as well as contractual matters and other disputes. See Item 8, "Financial Statements and Supplementary Data - Note 16: Contingencies" for more information on our current product liability litigation, as well as pricing and other litigation, investigations, and inquiries. 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 increasingly 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. Due to a very restrictive market for liability insurance, we are predominately self-insured for litigation liability losses for all of our currently marketed products, as well as for litigation or investigations related to our pricing practices or other similar matters. **Current (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. --- ## Modified: •Changes in foreign currency rates, interest rate risks, and inflation or deflation affect our results of operations. **Key changes:** - Reworded sentence: "As a global company, we face foreign currency risk exposure from fluctuating currency exchange rates, interest rate risk from our exposure to floating and variable interest rates, and existing and expected rates of inflation or deflation in the U.S." - Reworded sentence: "We are a net receiver of foreign currencies, and our results of operations are adversely impacted when the U.S." **Prior (2024):** As a global company, we face foreign currency risk exposure from fluctuating currency exchange rates, interest rate risk from our exposure to floating and variable interest rates, and inflation risk from existing and expected rates of inflation in the U.S. and other jurisdictions, each of which impacts our results of operations. In recent periods, significant fluctuations in currency rates and inflation have impacted our results of operations. We are a net receiver of foreign currencies, and our results of operations are 33 33 33 adversely impacted when the U.S. dollar is strong compared to foreign currencies. Further, in the event of an extreme devaluation of local currency in a particular market in which we operate, the price of our products could become unsustainable in the relevant market. Inflationary pressures in recent periods have also negatively impacted us and may continue to negatively impact us in various ways, including cost inflation, higher labor costs, and other higher expenses, with some of these higher expenses due in part to policy actions intended to curb inflation. See Item 7, "Management's Discussion and Analysis - Financial Condition and Liquidity" and Item 8, "Financial Statements and Supplementary Data - Note 1: Summary of Significant Accounting Policies and Implementation of New Financial Accounting Standards," for more details. **Current (2025):** As a global company, we face foreign currency risk exposure from fluctuating currency exchange rates, interest rate risk from our exposure to floating and variable interest rates, and existing and expected rates of inflation or deflation in the U.S. and other jurisdictions, each of which impacts our results of operations.

To compete successfully, we must continue to deliver to the market innovative, cost-effective products through internal innovation or business development that meet important medical needs, provide improved outcomes for patients, and deliver value to payers. Our product revenues and prospects are adversely affected by 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 drugs. 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. 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, including in the areas of manufacturing, clinical trials management, regulatory affairs, and sales and marketing, 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 ability to attract and retain talent in our increasingly competitive environment is further complicated by evolving employment trends. 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. 25 25 25 **Current (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. --- ## Modified: •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:** - Reworded sentence: "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." - Reworded sentence: "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." - Reworded sentence: "In recent years, U.S." - Reworded sentence: "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." - Reworded sentence: "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." **Prior (2024):** 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 drugs 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 a two-year reduction of data package protection. 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 addition, in December 2023, the U.S. presidential administration released a proposed framework that would permit the federal government to consider the price of a drug developed using federal funds as a factor in determining whether it may exercise "march-in rights" and license it to a third party to manufacture. A comment period on the proposal runs through February 6, 2024, and we are not able to predict whether a final rule will be adopted in accordance with the proposed framework. 28 28 28 Also in the U.S., in addition to the process for challenging patents set forth in the BPCIA, which applies to biologic 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 provides limited precedential value at the PTAB and no precedential value in federal district court, 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 outside the U.S. 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. We also face challenges from the distribution of counterfeit and illegally compounded versions of our genuine drugs, including as related to our products with GLP-1 receptor agonist activity. Counterfeits, and in some cases illegally compounded drugs, fraudulently claim to be, or claim to contain, genuine branded medicines. Counterfeit and illegally compounded drugs may not have the same safety, quality, and effectiveness as approved drugs, and may pose serious health risks to patients. Our reputation and business could suffer harm from counterfeit or illegally compounded drugs and our actions to stop or prevent illegal sales of such drugs may be costly or ineffective. **Current (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 --- ## Modified: •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:** - Reworded sentence: "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." - Reworded sentence: "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." - Reworded sentence: "Private Sector Dynamics" and "Regulations and Private Payer Actions Affecting Pharmaceutical Pricing, Reimbursement, and Access - U.S."" **Prior (2024):** We derived direct product and/or alliance revenues of more than $2 billion for each of Trulicity, Mounjaro, Verzenio, Taltz and Jardiance (including Glyxambi, Synjardy, and Trijardy XR) that collectively accounted for 63 percent of our total revenues in 2023. In particular, Trulicity and Mounjaro accounted for 36 percent of our total revenues in 2023 and we expect products with GLP-1 receptor agonist activity, including the recently launched Zepbound, 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 in demand, regulatory proceedings and investigations, negative publicity affecting doctor or patient confidence, pressure from existing or new competitive products, counterfeit and illegally compounded drugs, changes in labeling, pricing, and insufficient access, or supply shortages or disruptions for these products or any of our other major products could materially impact our results of operations. In addition, in the U.S., most of our products are distributed through wholesalers and if one of these significant wholesalers should encounter financial or other difficulties, it might decrease the amount of business the wholesaler does with us 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. 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 favor the use of generic products or otherwise 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." 27 27 27 **Current (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.

Many companies, including us, are and have been subject to investigations, litigation, and claims related to these practices asserted by governmental authorities and 34 34 34 other parties. These investigations, litigation, and claims have resulted in substantial expense and other significant consequences. The final outcomes of such investigations, litigation, and claims include criminal charges and fines, penalties, or other monetary or non-monetary remedies, including exclusion from U.S. federal and other healthcare programs. Such investigations, litigation, and claims have intensified and may continue to intensify as a result of evolving U.S. and foreign regulatory priorities. New business practices or commercial capabilities may subject us to additional scrutiny over compliance with applicable regulatory schemes and compliance obligations or expose us to new regulatory schemes and compliance obligations entirely. In addition, regulatory issues concerning compliance with cGMP, quality assurance, 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, delays or denials in new product approvals or line extensions or supplemental approvals of current products pending resolution of the issues, and reputational harm, any of which adversely affects our business. Regulatory oversight of the pharmaceutical industry entails judgment and interpretation, which can result in inconsistent administration of laws and regulations by health authorities. Regulatory compliance and processes in jurisdictions outside the U.S. may be particularly unpredictable and result in additional costs, uncertainties, and risks.U.S. and foreign governmental authorities are actively promulgating additional regulations that impact many aspects of our operations. These regulations are in some cases advanced with short notice. New regulations may undermine our ability to achieve business objectives, may be costly to implement, may provide only limited time for compliance, may change accounting and reporting standards, and may carry significant penalties for non-compliance. See Item 1, "Business - Government Regulation of Our Operations," for more details. Furthermore, there is an increased focus by foreign, federal, state, and local regulatory and legislative bodies regarding environmental policies relating to climate change, regulating greenhouse gas emissions, carbon taxes, emissions trading schemes, sustainability, human rights and equity matters, and disclosure regarding the foregoing, many of which may be ambiguous, inconsistent, dynamic or conflicting. We expect to experience increased restrictions and compliance costs, legal costs, and expenses related to such new or changing legal or regulatory requirements. Moreover, compliance with any such legal or regulatory requirements would require us to devote substantial time and attention to these matters. In addition, we may still be subject to penalties or potential litigation if such laws and regulations are interpreted or applied in a manner inconsistent with our practices. Additionally, we are subject to increased negative attention from the media, stockholders, activists, and other stakeholders on climate change, social, and sustainability matters. The perception that we have failed to act in a socially responsible manner, whether or not valid, results in adverse publicity that can negatively affect our business, brand, and reputation, as well as result in increased scrutiny from legislators and regulatory authorities. Moreover, from time to time we establish and publicly announce goals and commitments, including to reduce our impact on the environment. Our ability to achieve any stated environmental, social or governance goal, target or objective is subject to numerous factors and conditions, many of which are outside our control. Examples of such factors include evolving regulatory requirements affecting sustainability standards or disclosures or imposing different requirements, the availability of requisite financing, and the availability of suppliers that can meet our sustainability and other goals. If we fail to achieve, are perceived to have failed or been delayed in achieving, or improperly report our progress toward achieving these goals and commitments, it could negatively affect our reputation, brand, or investor confidence, and expose us to enforcement actions and litigation. 35 35 35 **Current (2025):** The marketing, promotional, and pricing practices of pharmaceutical manufacturers, as well as the manner in which manufacturers interact with purchasers, prescribers, and patients, are subject to extensive scrutiny and regulation.

Regulatory oversight of the pharmaceutical industry entails judgment and interpretation, which can result in varying interpretations of laws and regulations by health and other authorities. In addition, changing political leadership, including the new presidential administration and regulatory leadership in the U.S., may propose, enact, or pursue policy, regulatory, and enforcement changes that create additional uncertainty for our business. Regulatory compliance and processes in jurisdictions outside the U.S. may be particularly unpredictable and result in additional costs, uncertainties, and risks. U.S. and foreign governmental authorities are actively promulgating additional regulations and guidance that impact many aspects of our operations. These regulations are in some cases advanced with short notice. New regulations may undermine our ability to achieve business objectives, may be costly to implement, may provide only limited time for compliance, may change accounting and reporting standards, and may carry significant penalties for non-compliance. See Item 1, "Business - Government Regulation of Our Operations and Products," for more details. We rely on the FDA and other regulatory bodies for appropriate oversight, administration and enforcement across our industry, anyone marketing or purporting to market medicines, and public health. Oversight, administrative, and enforcement changes, delays, inconsistencies, lapses, and failures could materiality impact our business and reputation. See Item 1, "Business - Government Regulation of Our Operations and Products," for additional information on regulatory risks, including as related to counterfeit, misbranded, adulterated, and compounded medicines. Furthermore, there is an increased focus by foreign, federal, state, and local regulatory and legislative bodies on legislation and policies relating to climate change, regulating greenhouse gas emissions, carbon taxes, emissions trading schemes, sustainability, human rights and related due diligence, workforce matters, and disclosure regarding the foregoing, many of which may be ambiguous, inconsistent, dynamic or conflicting. We have experienced increased compliance costs, legal costs, and expenses related to such new or changing legal or regulatory requirements. Moreover, compliance with any such legal or regulatory requirements requires us to devote time and attention, which may be substantial, to these matters. In addition, we may still be subject to penalties or potential litigation if such laws and regulations are interpreted or applied in a manner inconsistent with our practices. Additionally, there is increased attention from the media, stockholders, activists, political leadership, regulatory authorities, and other stakeholders on climate, social, and other sustainability matters. The perception that we or others in our industry or supply chain have failed to act in an appropriate manner, whether or not valid, results in publicity that can negatively affect our business, brand, and reputation, as well as result in increased scrutiny from political leadership, legislators and regulatory authorities. For example, negative perception of inclusion initiatives, whether due to a perceived over- or under-pursuit of such initiatives, may result in issues hiring or retaining employees, as well as potential investigations, enforcement actions, litigation, reputational harm, or other adverse impacts. Moreover, from time to time we establish and publicly announce goals, initiatives, and commitments, including on climate, social, and other sustainability matters. Our ability to achieve any of these stated goals, targets or objectives is subject to numerous factors and conditions, many of which are outside our control. Examples of such factors include evolving regulatory requirements affecting sustainability standards or disclosures or imposing different requirements, and the availability of suppliers that can meet our sustainability and other goals. If we fail to achieve, are perceived to have failed or been delayed in achieving, or improperly report our progress toward achieving these goals, initiatives, and commitments, it could negatively affect our reputation, brand, or investor confidence, and expose us to investigations, enforcement actions and litigation. Conversely, our pursuit or achievement of such goals, initiatives, and commitments may not be viewed favorably by certain stakeholders and could increase scrutiny of our business, negatively affect our reputation, or expose us to investigations, enforcement actions and litigation. 36 36 36 --- ## Modified: •Reliance on third-party relationships and outsourcing arrangements could adversely affect our business. **Key changes:** - Added sentence: "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." - Added sentence: "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." - Added sentence: "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." - Added sentence: "Among other third-party providers, we, and the pharmaceutical industry generally, depend on China-based suppliers for portions of our supply chain." - Added sentence: "officials are increasingly considering legislation or other actions that are intended to limit supply chain reliance on China, including the BIOSECURE Act." **Prior (2024):** 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. In some cases, product or indication approvals depend on the outcome of regulatory inspections of third parties on which we rely. For example, in September 2023, the FDA issued a complete response letter for our lebrikizumab BLA for the treatment of moderate to severe atopic dermatitis. In the letter, the FDA cited findings that arose during a multi-sponsor inspection of a third-party, contract manufacturing organization that included the monoclonal antibody drug substance for lebrikizumab. We may encounter similar difficulties in the future, which could delay or prevent product launches and otherwise negatively affect our business, results, and reputation. Outsourcing involves many risks, including the risk that third parties may not perform to our standards or legal requirements, including applicable requirements for diversity in clinical trials; 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. 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. **Current (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.

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. --- *Data sourced from SEC EDGAR.
