Product Sales Excluding Veklury Increased 4% Year-Over-Year to $6.3 billion Biktarvy Sales Increased 7% Year-Over-Year to $3.1 billion FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) announced today its first quarter 2025 results of operations. “Gilead had a strong start to the year driven by excellent commercial and clinical execution along with disciplined expense management,” said Daniel O’Day, Gilead’s Chairman and Chief Executive Officer. “Our base business grew 4% year-over-year, primarily led by Biktarvy’s continued strength, and we announced positive topline Phase 3 results for Trodelvy plus pembrolizumab in first line PD-L1+ metastatic triple negative breast cancer. With the upcoming June PDUFA date for lenacapavir for HIV prevention, and continued progress across our diverse pipeline, we look forward to building on our positive momentum throughout the year.” First Quarter 2025 Financial Results Total first quarter 2025 revenue of $6.7 billion remained flat compared to the same period in 2024, with lower Veklury® (remdesivir) and Oncology sales offset by higher HIV and Liver Disease sales. Diluted earnings (loss) per share (“EPS”) was $1.04 in the first quarter 2025 compared to $(3.34) in the same period in 2024. The increase was primarily driven by prior year charges that did not repeat, including the impact of a $3.9 billion acquired in-process research and development ("IPR&D") expense related to the acquisition of CymaBay Therapeutics, Inc. (“CymaBay”), as well as a pre-tax IPR&D impairment of $2.4 billion related to assets acquired by Gilead from Immunomedics, Inc. (“Immunomedics”) in 2020. This increase was partially offset by higher tax expense and higher net unrealized losses on equity investments in the first quarter 2025. Non-GAAP diluted EPS was $1.81 in the first quarter 2025 compared to $(1.32) in the same period in 2024. The increase was primarily driven by the prior year IPR&D expense related to the CymaBay acquisition. As of March 31, 2025, Gilead had $7.9 billion of cash and cash equivalents compared to $10.0 billion as of December 31, 2024. During the first quarter 2025, Gilead generated $1.8 billion in operating cash flow. During the first quarter 2025, Gilead paid dividends of $1.0 billion and repurchased $730 million of common stock. In addition, Gilead repaid $1.8 billion of Senior Notes in February 2025. First Quarter 2025 Product Sales Total first quarter 2025 product sales decreased 1% to $6.6 billion compared to the same period in 2024. Total first quarter 2025 product sales excluding Veklury increased 4% to $6.3 billion compared to the same period in 2024, primarily due to higher HIV and Liver Disease sales, partially offset by lower Oncology sales. HIV product sales increased 6% to $4.6 billion in the first quarter 2025 compared to the same period in 2024, primarily driven by higher average realized price and demand. Biktarvy®(bictegravir 50mg/emtricitabine (“FTC”) 200mg/tenofovir alafenamide (“TAF”) 25mg) sales increased 7% to $3.1 billion in the first quarter 2025 compared to the same period in 2024, primarily driven by higher demand. Descovy®(FTC 200mg/TAF 25mg) sales increased 38% to $586 million in the first quarter 2025 compared to the same period in 2024, primarily driven by higher average realized price and higher demand. The Liver Disease portfolio sales increased 3% to $758 million in the first quarter 2025 compared to the same period in 2024. This was primarily driven by increased demand in products for primary biliary cholangitis (“PBC”), chronic hepatitis B virus (“HBV”) and chronic hepatitis delta virus (“HDV”), partially offset by lower average realized price for chronic hepatitis C virus (“HCV”) products. Veklury sales decreased 45% to $302 millionin the first quarter 2025 compared to the same period in 2024, primarily driven by lower rates of COVID-19 related hospitalizations across regions. Cell Therapy product sales decreased 3% to $464 million in the first quarter 2025 compared to the same period in 2024. Yescarta® (axicabtagene ciloleucel) sales increased 2% to $386 million in the first quarter 2025 compared to the same period in 2024, primarily driven by higher average realized price and increased rest of world demand, partially offset by lower demand in the United States. Tecartus® (brexucabtagene autoleucel) sales decreased 22% to $78 million in the first quarter 2025 compared to the same period in 2024, primarily reflecting lower demand in the United States. Trodelvy® (sacituzumab govitecan-hziy) sales decreased 5% to $293 million in the first quarter 2025 compared to the same period in 2024, primarily driven by inventory dynamics and lower average realized price, partially offset by higher demand. First Quarter 2025 Product Gross Margin, Operating Expenses and Effective Tax Rate Product gross margin was 76.7% in the first quarter 2025 compared to 76.6% in the same period in 2024. Non-GAAP product gross margin was 85.5% in the first quarter 2025 compared to 85.4% in the same period in 2024. Research and development (“R&D”) expenses were $1.4 billion in the first quarter 2025 compared to $1.5 billion in the same period in 2024, primarily due to lower clinical manufacturing activities and prior year CymaBay acquisition-related expenses that did not repeat. Non-GAAP R&D expenses were $1.3 billion in the first quarter 2025 compared to $1.4 billion in the same period in 2024, primarily due to lower clinical manufacturing activities. Acquired IPR&D expenses were $253 million in the first quarter 2025, primarily reflecting expenses related to the strategic partnership with LEO Pharma A/S (“LEO Pharma”) announced in January 2025. Selling, general and administrative (“SG&A”) expenses were $1.3 billion in the first quarter 2025 compared to $1.4 billion in the same period in 2024, primarily driven by prior year CymaBay acquisition-related expenses that did not repeat as well as lower corporate expenses, partially offset by incremental selling and marketing expenses in the United States. Non-GAAP SG&A expenses were $1.2 billion in the first quarter 2025 compared to $1.3 billion in the same period in 2024. This was primarily driven by lower corporate expenses, partially offset by incremental selling and marketing expenses in the United States. The effective tax rate (“ETR”) was 20.2% in the first quarter 2025 compared to 7.0% in the same period in 2024, and the non-GAAP ETR was 16.3% in the first quarter 2025 compared to (29.8)% in the same period in 2024. These changes primarily reflect the prior year non-deductible acquired IPR&D charge related to the CymaBay acquisition, and higher tax benefits from stock-based compensation.

Non-GAAP Financial Information The information presented in this document has been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), unless otherwise noted as non-GAAP. Management believes non-GAAP information is useful for investors, when considered in conjunction with Gilead’s GAAP financial information, because management uses such information internally for its operating, budgeting and financial planning purposes. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Gilead’s operating results as reported under GAAP. Non-GAAP financial information generally excludes acquisition-related expenses including amortization of acquired intangible assets and other items that are considered unusual or not representative of underlying trends of Gilead’s business, fair value adjustments of equity securities and discrete and related tax charges or benefits associated with such exclusions as well as changes in tax-related laws and guidelines, transfers of intangible assets between certain legal entities, and legal entity restructurings. Although Gilead consistently excludes the amortization of acquired intangible assets from the non-GAAP financial information, management believes that it is important for investors to understand that such intangible assets were recorded as part of acquisitions and contribute to ongoing revenue generation.Non-GAAP measures may be defined and calculated differently by other companies in the same industry. Reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided in the accompanying tables.

Forward-Looking Statements Statements included in this press release that are not historical in nature are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Gilead cautions readers that forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially. These risks and uncertainties include those relating to: Gilead’s ability to achieve its full year 2025 financial guidance, including as a result of the uncertainty of the amount and timing of Veklury revenues, the impact of the Inflation Reduction Act, changes in U.S. regulatory or legislative policies, and changes in U.S. trade policies, including tariffs; Gilead’s ability to make progress on any of its long-term ambitions or priorities laid out in its corporate strategy; Gilead’s ability to accelerate or sustain revenues for its virology, oncology and other programs; Gilead’s ability to realize the potential benefits of acquisitions, collaborations or licensing arrangements, including the acquisitions of CymaBay and Immunomedics, and the arrangement with LEO Pharma; patent protection and estimated loss of exclusivity for our products and product candidates; Gilead’s ability to initiate, progress or complete clinical trials within currently anticipated timeframes or at all, the possibility of unfavorable results from ongoing and additional clinical trials, including those involving Biktarvy, Trodelvy, lenacapavir, teropavimab and zinlirvimab, and the risk that safety and efficacy data from clinical trials may not warrant further development of Gilead’s product candidates or the product candidates of Gilead’s strategic partners; Gilead’s ability to submit new drug applications for new product candidates or expanded indications in the currently anticipated timelines, including for lenacapavir for HIV PrEP; Gilead’s ability to receive or maintain regulatory approvals in a timely manner or at all, including for lenacapavir for PrEP, and the risk that any such approvals, if granted, may be subject to significant limitations on use and may be subject to withdrawal or other adverse actions by the applicable regulatory authority; Gilead’s ability to successfully commercialize its products; the risk of potential disruptions to the manufacturing and supply chain of Gilead’s products; pricing and reimbursement pressures from government agencies and other third parties, including required rebates and other discounts; a larger than anticipated shift in payer mix to more highly discounted payer segments; market share and price erosion caused by the introduction of generic versions of Gilead products; the risk that physicians and patients may not see advantages of Gilead’s products over other therapies and may therefore be reluctant to prescribe the products, including Livdelzi/Lyvdelzi; and other risks identified from time to time in Gilead’s reports filed with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K. In addition, Gilead makes estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures. Gilead bases its estimates on historical experience and on various other market specific and other relevant assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. There may be other factors of which Gilead is not currently aware that may affect matters discussed in the forward-looking statements and may also cause actual results to differ significantly from these estimates. Further, results for the quarter ended March 31, 2025 are not necessarily indicative of operating results for any future periods. Gilead directs readers to its press releases, annual reports on Form 10-K, quarterly reports on Form 10-Q and other subsequent disclosure documents filed with the SEC.

Product Sales Excluding Veklury Increased 8% Year-Over-Year to $26.8 billion for Full Year 2024 Biktarvy Sales Increased 13% Year-Over-Year to $13.4 billion for Full Year 2024 Oncology Sales Increased 12% Year-Over-Year to $3.3 billion for Full Year 2024 FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the fourth quarter and full year 2024. “Gilead delivered another exceptionally strong full year and fourth quarter, with growth in our base business product sales of 8% for 2024 and 13% year-over-year for the fourth quarter,” said Daniel O’Day, Gilead’s Chairman and Chief Executive Officer. “From this foundation of commercial strength, we are planning for the potential launch of lenacapavir for HIV PrEP in Summer 2025, with its unique opportunity to extend the reach of HIV prevention. This potential in HIV, along with our strong and diverse portfolio, and improved operational efficiencies, positions Gilead to deliver increasing patient impact and compelling shareholder returns in the years ahead.” Fourth Quarter 2024 Financial Results Total fourth quarter 2024 revenue increased 6% to $7.6 billion compared to the same period in 2023, primarily due to higher sales in HIV, as well as in Oncology and Liver Disease, partially offset by lower sales of Veklury® (remdesivir). Diluted Earnings Per Share (“EPS”) increased to $1.42 in the fourth quarter 2024 compared to $1.14 in the same period in 2023, primarily driven by lower costs of goods sold, higher product sales and lower acquired in-process research and development ("IPR&D") expenses, partially offset by higher operating expenses as well as unrealized losses on equity investments in 2024 compared to gains in 2023. Non-GAAP diluted EPS increased to $1.90 in the fourth quarter 2024 compared to $1.72 in the same period in 2023. The increase was primarily driven by higher product sales and lower acquired IPR&D expenses, partially offset by higher operating expenses. As of December 31, 2024, Gilead had $10.0 billion of cash, cash equivalents and marketable debt securities compared to $8.4 billion as of December 31, 2023. During the fourth quarter 2024, Gilead generated $3.0 billion in operating cash flow. During the fourth quarter 2024, Gilead issued senior unsecured notes in an aggregate principal amount of $3.5 billion, paid cash dividends of $973 million and utilized $350 million to repurchase common stock. Fourth Quarter 2024 Product Sales Total fourth quarter 2024 product sales increased 7% to $7.5 billion compared to the same period in 2023. Total product sales excluding Veklury increased 13% to $7.2 billion compared to the same period in 2023, primarily due to higher sales in HIV, as well as in Oncology and Liver Disease. HIV product sales increased 16% to $5.5 billion in the fourth quarter 2024 compared to the same period in 2023, primarily driven by higher demand, higher average realized price and favorable inventory dynamics. Biktarvy® (bictegravir 50mg/emtricitabine (“FTC”) 200mg/tenofovir alafenamide (“TAF”) 25mg) sales increased 21% to $3.8 billion in the fourth quarter 2024 compared to the same period in 2023, primarily driven by higher demand, favorable inventory dynamics and higher average realized price. Descovy® (FTC 200mg/TAF 25mg) sales increased 21% to $616 million in the fourth quarter 2024 compared to the same period in 2023, primarily driven by higher demand, higher average realized price and favorable inventory dynamics. The Liver Disease portfolio sales increased 4% to $719 million in the fourth quarter 2024 compared to the same period in 2023. This was primarily driven by the launch of Livdelzi® (seladelpar) in primary biliary cholangitis (“PBC”), and increased demand in products for chronic hepatitis B virus (“HBV”) and chronic hepatitis delta virus (“HDV”), partially offset by lower demand and average realized price in products for chronic hepatitis C virus (“HCV”). Veklury sales decreased 53% to $337 million in the fourth quarter 2024 compared to the same period in 2023, primarily driven by lower rates of COVID-19 related hospitalizations, particularly in the United States. Cell Therapy product sales increased 5% to $488 million in the fourth quarter 2024 compared to the same period in 2023. Yescarta® (axicabtagene ciloleucel) sales increased 6% to $390 million in the fourth quarter 2024 compared to the same period in 2023, primarily driven by higher average realized price and increased demand outside of the United States, partially offset by lower demand in the United States. Tecartus® (brexucabtagene autoleucel) sales of $98 million in the fourth quarter 2024 were flat compared to the same period in 2023, reflecting increased demand outside of the United States, offset by lower demand in the United States. Trodelvy® (sacituzumab govitecan-hziy) sales increased 19% to $355 million in the fourth quarter 2024 compared to the same period in 2023, primarily driven by increased demand in all regions, as well as higher average realized price. Fourth Quarter 2024 Product Gross Margin, Operating Expenses and Tax Product gross margin was 79.0% in the fourth quarter 2024 compared to 70.4% in the same period in 2023, primarily driven by prior year restructuring expenses related to changes in our manufacturing strategy. Non-GAAP product gross margin was 86.7% in the fourth quarter 2024 compared to 86.1% in the same period in 2023. Research and development (“R&D”) expenses were $1.6 billion in the fourth quarter 2024 compared to $1.4 billion in the same period in 2023, primarily due to incremental investments and clinical activities across our portfolio and the impact of a prior year valuation adjustment to the MYR-related contingent consideration that did not repeat. Non-GAAP R&D expenses were $1.6 billion in the fourth quarter 2024 compared to $1.5 billion in the same period in 2023, primarily due to incremental investments and clinical activities across our portfolio. Acquired IPR&D expenses were $(11) million in the fourth quarter 2024, reflecting expenses related to the Terray Therapeutics, Inc. (“Terray”) and Tubulis GmbH (“Tubulis”) collaborations, offset by a favorable adjustment related to the CymaBay Therapeutics, Inc. (“CymaBay”) acquisition. Selling, general and administrative (“SG&A”) and non-GAAP SG&A expenses were $1.9 billion in the fourth quarter 2024 compared to $1.6 billion in the same period in 2023, primarily driven by a litigation accrual and higher sales and marketing spending, including launch preparation activities for lenacapavir for the investigational use of HIV pre-exposure prophylaxis (“PrEP”) as well as for Livdelzi. The effective tax rate (“ETR”) was 17.8% in the fourth quarter 2024 compared to 14.3% in the same period in 2023, primarily due to prior year settlements with tax authorities and non-taxable unrealized gains and losses on equity investments. Non-GAAP ETR was 19.2% in the fourth quarter 2024 compared to 17.1% in the same period in 2023, primarily due to prior year settlements with tax authorities. Full Year 2024 Financial Results Total full year 2024 revenue increased 6% to $28.8 billion compared to 2023, primarily due to higher sales in HIV, Oncology and Liver Disease, partially offset by lower sales of Veklury. Diluted EPS decreased to $0.38 in the full year 2024 compared to $4.50 in 2023. The decrease was primarily driven by a pre-tax IPR&D impairment charge of $4.2 billion, or $2.49 per share net of tax impact, related to assets acquired by Gilead from Immunomedics, Inc. (“Immunomedics”) in 2020, and acquired IPR&D charges of $3.9 billion, or $3.14 per share, in the first quarter 2024 related to the acquisition of CymaBay, partially offset by higher product sales. Non-GAAP diluted EPS decreased to $4.62 in the full year 2024 compared to $6.72 in 2023. This was primarily driven by higher acquired IPR&D expenses related to the CymaBay acquisition and higher income tax expense, partially offset by higher product sales. Full Year 2024 Product Sales Total full year 2024 product sales increased 6% to $28.6 billion compared to 2023. Total product sales excluding Veklury increased 8% to $26.8 billion in the full year 2024 compared to 2023, primarily driven by higher sales in HIV, Oncology and Liver Disease. HIV product sales increased 8% to $19.6 billion in the full year 2024 compared to 2023, primarily driven by higher demand, as well as the impact of higher average realized price. Biktarvy sales increased 13% to $13.4 billion in the full year 2024 compared to 2023, primarily driven by higher demand. Descovy sales increased 6% to $2.1 billion in the full year 2024 compared to 2023, primarily driven by higher demand, partially offset by lower average realized price. The Liver Disease portfolio sales increased 9% to $3.0 billion in the full year 2024 compared to 2023. The increase was primarily due to higher demand across all liver diseases. Veklury sales decreased 18% to $1.8 billion in the full year 2024 compared to 2023, primarily driven by lower rates of COVID-19 related hospitalizations. Cell Therapy product sales increased 6% to $2.0 billion in the full year 2024 compared to 2023. Yescarta sales increased 5% to $1.6 billion in the full year 2024 compared to 2023, primarily driven by increased demand outside of the United States and higher average realized price, partially offset by lower demand in the United States. Tecartus sales increased 9% to $403 million in the full year 2024 compared to 2023, primarily driven by increased demand outside of the United States, partially offset by lower demand in the United States. Trodelvy sales increased 24% to $1.3 billion in the full year 2024 compared to 2023, primarily driven by increased demand in all regions. Full Year 2024 Product Gross Margin, Operating Expenses and Tax Product gross margin was 78.2% in the full year 2024 compared to 75.9% in 2023, primarily driven by prior year restructuring expenses related to changes in our manufacturing strategy. Non-GAAP product gross margin was 86.2% in the full year 2024 compared to 86.3% in 2023. R&D expenses were $5.9 billion in the full year 2024 compared to $5.7 billion in 2023, primarily driven by restructuring costs and integration expenses related to the CymaBay acquisition. Non-GAAP R&D expenses of $5.7 billion in the full year 2024 were flat compared to 2023. Acquired IPR&D expenses were $4.7 billion in the full year 2024 compared to $1.2 billion in 2023, primarily reflecting the acquisition of CymaBay. SG&A expenses of $6.1 billion in the full year 2024 were flat compared to 2023, reflecting higher sales and marketing spending, including launch preparation activities for lenacapavir for the investigational use of HIV PrEP as well as for Livdelzi, integration costs related to the acquisition of CymaBay, and restructuring expenses, offset by lower expenses related to legal matters. Non-GAAP SG&A expenses were $5.9 billion in the full year 2024 compared to $6.1 billion in 2023, primarily driven by lower expenses related to legal matters, partially offset by higher sales and marketing spending, including launch preparation activities for lenacapavir for the investigational use of HIV PrEP as well as for Livdelzi. The ETR was 30.5% in the full year 2024 compared to 18.2% in 2023, primarily driven by the non-deductible acquired IPR&D charge for CymaBay and prior year decrease in tax reserves that did not repeat, partially offset by the tax impact of a legal entity restructuring and Immunomedics IPR&D impairment expense, as well as current year settlements with tax authorities and remeasurement of certain deferred tax liabilities. Non-GAAP ETR was 25.9% in the full year 2024 compared to 15.2% in 2023, primarily due to the non-deductible acquired IPR&D charge for CymaBay and a prior year decrease in tax reserves that did not repeat, partially offset by current year settlements with tax authorities. Guidance and Outlook For the full-year 2025, Gilead expects: (in millions, except per share amounts) February 11, 2025 Guidance Low End High End Product sales $ 28,200 $ 28,600 Product sales excluding Veklury $ 26,800 $ 27,200 Veklury $ 1,400 $ 1,400 Diluted EPS $ 5.95 $ 6.35 Non-GAAP diluted EPS $ 7.70 $ 8.10 Additional information and a reconciliation between GAAP and non-GAAP financial information for the 2025 guidance is provided in the accompanying tables.

Non-GAAP Financial Information The information presented in this document has been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), unless otherwise noted as non-GAAP. Management believes non-GAAP information is useful for investors, when considered in conjunction with Gilead’s GAAP financial information, because management uses such information internally for its operating, budgeting and financial planning purposes. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Gilead’s operating results as reported under GAAP. Non-GAAP financial information generally excludes acquisition-related expenses including amortization of acquired intangible assets and other items that are considered unusual or not representative of underlying trends of Gilead’s business, fair value adjustments of equity securities and discrete and related tax charges or benefits associated with such exclusions as well as changes in tax-related laws and guidelines, transfers of intangible assets between certain legal entities, and legal entity restructurings. Although Gilead consistently excludes the amortization of acquired intangible assets from the non-GAAP financial information, management believes that it is important for investors to understand that such intangible assets were recorded as part of acquisitions and contribute to ongoing revenue generation. Non-GAAP measures may be defined and calculated differently by other companies in the same industry. Reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures are provided in the accompanying tables.

Forward-Looking Statements Statements included in this press release that are not historical in nature are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Gilead cautions readers that forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially. These risks and uncertainties include those relating to: Gilead’s ability to achieve its full year 2025 financial guidance, including as a result of the uncertainty of the amount and timing of Veklury revenues; Gilead’s ability to make progress on any of its long-term ambitions or priorities laid out in its corporate strategy; Gilead’s ability to accelerate or sustain revenues for its virology, oncology and other programs; Gilead’s ability to realize the potential benefits of acquisitions, collaborations or licensing arrangements, including the arrangements with Arcellx, LEO Pharma, Terray and Tubulis; patent protection and estimated loss of exclusivity for our products and product candidates; Gilead’s ability to initiate, progress or complete clinical trials within currently anticipated timeframes or at all, the possibility of unfavorable results from ongoing and additional clinical trials, including those involving Biktarvy, Tecartus, Trodelvy, Yescarta, anito-cel, lenacapavir and seladelpar (such as the ASSURE, iMMagine-1, PURPOSE 1 and 2, and RESPONSE studies), and the risk that safety and efficacy data from clinical trials may not warrant further development of Gilead’s product candidates or the product candidates of Gilead’s strategic partners; Gilead’s ability to submit new drug applications for new product candidates or expanded indications in the currently anticipated timelines, including for lenacapavir for HIV PrEP and seladelpar for PBC; Gilead’s ability to receive or maintain regulatory approvals in a timely manner or at all, and the risk that any such approvals, if granted, may be subject to significant limitations on use and may be subject to withdrawal or other adverse actions by the applicable regulatory authority; Gilead’s ability to successfully commercialize its products; the risk of potential disruptions to the manufacturing and supply chain of Gilead’s products; pricing and reimbursement pressures from government agencies and other third parties, including required rebates and other discounts; a larger than anticipated shift in payer mix to more highly discounted payer segments; market share and price erosion caused by the introduction of generic versions of Gilead products; the risk that physicians and patients may not see advantages of Gilead’s products over other therapies and may therefore be reluctant to prescribe the products, including Livdelzi; and other risks identified from time to time in Gilead’s reports filed with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K. In addition, Gilead makes estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures.
