Product Sales Excluding Veklury Increased 4% Year-Over-Year to $28.0 billion for Full Year 2025 Biktarvy Sales Increased 7% Year-Over-Year to $14.3 billion for Full Year 2025 FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the fourth quarter and full year 2025. “Our fourth quarter and full-year results close out a very strong year for Gilead overall, including the successful U.S. launch of Yeztugo, the world’s first twice-yearly HIV prevention therapy, and continued growth for Biktarvy and Descovy,” said Daniel O’Day, Gilead’s Chairman and Chief Executive Officer. “In 2026, our potential new launches include two cancer therapies and an additional HIV treatment option, and we look forward to building on the launches of Yeztugo and Livdelzi for liver disease. As we continue to increase our positive impact on healthcare, Gilead is well positioned for continued growth in 2026 and beyond.” Fourth Quarter 2025 Financial Results Total fourth quarter 2025 revenues increased 5% to $7.9 billion compared to the same period in 2024, primarily driven by higher sales of HIV and Liver Disease products, partially offset by lower sales of Veklury® (remdesivir). Diluted earnings per share (“EPS”) was $1.74 in the fourth quarter 2025 compared to $1.42 in the same period in 2024. The increase was primarily driven by higher income tax benefits, net unrealized gains from equity securities and higher product sales, as well as lower selling, general and administrative (“SG&A”) expenses. The increase was partially offset by higher acquired in-process research and development (“IPR&D”) expenses and an IPR&D impairment charge related to assets acquired as part of the MYR GmbH (“MYR”) acquisition. Non-GAAP diluted EPS of $1.86 in the fourth quarter 2025 compared to $1.90 in the same period in 2024. The decrease was primarily driven by higher acquired IPR&D expenses, partially offset by higher product sales and lower SG&A expenses. As of December 31, 2025, Gilead had $10.6 billion of cash, cash equivalents and marketable debt securities compared to $10.0 billion as of December 31, 2024. During the fourth quarter 2025, Gilead generated $3.3 billion in operating cash flow. During the fourth quarter 2025, Gilead paid dividends of $1.0 billion and repurchased $230 million of common stock.

Total fourth quarter 2025 product sales excluding Veklury increased 7% to $7.7 billion compared to the same period in 2024, primarily due to higher sales of HIV and Liver Disease products. HIV product sales increased 6% to $5.8 billion in the fourth quarter 2025 compared to the same period in 2024, primarily driven by higher demand for HIV prevention and treatment. Biktarvy®(bictegravir 50mg/emtricitabine (“FTC”) 200mg/tenofovir alafenamide (“TAF”) 25mg) sales increased 5% to $4.0 billion in the fourth quarter 2025 compared to the same period in 2024, primarily driven by higher demand and favorable inventory dynamics, partially offset by lower average realized price. Descovy®(FTC 200mg/TAF 25mg) sales increased 33% to $819 million in the fourth quarter 2025 compared to the same period in 2024, primarily driven by higher average realized price and higher demand for HIV prevention. The Liver Disease portfolio sales increased 17% to $844 million in the fourth quarter 2025 compared to the same period in 2024, primarily driven by higher demand for Livdelzi® (seladelpar). Veklury sales decreased 37% to $212 millionin the fourth quarter 2025 compared to the same period in 2024, primarily driven by lower rates of COVID-19-related hospitalizations. Cell Therapy product sales decreased 6% to $458 million in the fourth quarter 2025 compared to the same period in 2024, reflecting ongoing competitive headwinds. Yescarta® (axicabtagene ciloleucel) sales decreased 6% to $368 million in the fourth quarter 2025 compared to the same period in 2024, primarily driven by in- and out-of-class competition.

Non-GAAP SG&A expenses were $1.7 billion in the fourth quarter 2025 compared to $1.9 billion in the same period in 2024, primarily due to lower expenses related to legal matters and corporate initiatives. The effective tax rate (“ETR”) was (5.0)% in the fourth quarter 2025 compared to 17.8% in the same period in 2024, primarily driven by a tax benefit from a settlement with a tax authority related to a prior year legal entity restructuring and a tax benefit from the IPR&D impairment charge related to assets acquired as part of the MYR acquisition. The non-GAAP ETR was 20.5% in the fourth quarter 2025 compared to 19.2% in the same period in 2024.

SG&A expenses were $5.8 billion in the full year 2025 compared to $6.1 billion in 2024, decreasing primarily due to lower corporate, legal, acquisition-related integration and restructuring expenses, partially offset by higher HIV promotional expenses and donations of equity securities made to the Gilead Foundation. Non-GAAP SG&A expenses were $5.6 billion in the full year 2025 compared to $5.9 billion in 2024, decreasing primarily due to lower expenses related to corporate initiatives and legal matters, partially offset by higher HIV promotional expenses.

Key Updates Since Our Last Quarterly Release Virology Announced positive topline Phase 3 results from the ARTISTRY-1 and ARTISTRY-2 trials, evaluating our investigational daily oral single-tablet regimen of bictegravir 75mg and lenacapavir 50mg (“BIC/LEN”) for virologically suppressed adults with HIV. BIC/LEN met its primary endpoints demonstrating non-inferiority to baseline multi-tablet antiviral regimens (ARTISTRY-1) and Biktarvy (ARTISTRY-2). Exercised option to license investigational herpes simplex virus helicase-primase inhibitor programs ABI-1179 and ABI-5366 from Assembly Biosciences, Inc. (“Assembly”). Announced the first delivery of lenacapavir for PrEP in sub-Saharan African countries Eswatini and Zambia through the U.S. President’s Emergency Plan for AIDS Relief. Oncology Announced that the Phase 3 ASCENT-07 study evaluating the investigational use of Trodelvy versus chemotherapy in first-line post-endocrine HR+/HER2- metastatic breast cancer did not meet its primary endpoint of progression-free survival as assessed by Blinded Independent Central Review. Overall survival, a secondary endpoint, was not mature at the time of the primary analysis, however, a favorable early trend compared to chemotherapy was observed in the Trodelvy arm. In addition, no new safety signals were identified in this patient population. The results from this study were presented at the 2025 San Antonio Breast Cancer Symposium. Announced the discontinuation of the Phase 3 STAR-221 study, in partnership with Arcus Biosciences, Inc. (“Arcus”), evaluating the anti-TIGIT antibody domvanalimab (“dom”) plus zimberelimab (“zim”) and chemotherapy in first-line HER2- advanced gastric and esophageal cancers. The decision was based on the recommendation of the Independent Data Monitoring Committee, following review of data from a pre-specified interim analysis. Additionally, Gilead and Arcus will discontinue the Phase 2 EDGE-Gastric study evaluating dom and zim regimens in upper gastrointestinal cancers. Dom and zim are investigational products and are not approved anywhere globally. Cell Therapy Announced a new label update for Yescarta that removes a limitation around Primary Central Nervous System Lymphoma, an ultra-rare cancer affecting a highly vulnerable patient population. Yescarta is the only CAR-T therapy in relapsed or refractory large B-cell lymphoma (“R/R LBCL”) to have this limitation removed. Presented new positive data, with our partner Arcellx, Inc. (“Arcellx”), from the pivotal Phase 2 iMMagine-1 trial evaluating the investigational CAR T-cell therapy anitocabtagene autoleucel in 4L+ R/R multiple myeloma at the 2025 American Society of Hematology (“ASH”). Presented initial Phase 1 data for KITE-753 and KITE-363, evaluating two investigational bicistronic CAR T-cell therapies in patients with R/R LBCL at ASH 2025. Presented a new analysis of Yescarta from the Phase 3 ZUMA-7 and Phase 2 ALYCANTE study in patients with R/R LBCL at ASH 2025. The data demonstrated consistent benefits of Yescarta among patients with R/R LBCL, including those ineligible for previous standard of care chemotherapy and stem cell transplant. Inflammation Presented new long-term data from the Phase 3 ASSURE study for Livdelzi, which reinforce the safety and efficacy of Livdelzi for people living with primary biliary cholangitis over 3 years, including data on switching from obeticholic acid. The data were presented at the American Association for the Study of Liver Diseases meeting. Corporate The Board declared a quarterly dividend of $0.82 per share of common stock for the first quarter of 2026. The dividend is payable on March 30, 2026, to stockholders of record at the close of business on March 13, 2026. Future dividends will be subject to Board approval. Appointed Keeley Cain Wettan as Executive Vice President, General Counsel, Legal and Compliance. Announced an agreement with the U.S. government to lower the cost of medicines for Americans, reinforcing a commitment to U.S.-based innovation, affordability and global health leadership. Certain amounts and percentages in this press release may not sum or recalculate due to rounding.

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.

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 2026 financial guidance, including as a result of the uncertainty of the amount and timing of Veklury revenues, the impact from Medicare Part D pricing reform in the Inflation Reduction Act, the expiration of subsidies related to the Affordable Care Act, our most-favored-nation pricing agreement with the U.S. government, 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, inflammation and other programs; Gilead’s ability to realize the potential benefits of acquisitions, collaborations or licensing arrangements, including the arrangements with Arcellx, Arcus, Assembly and the U.S. government; the risk that Gilead’s U.S. manufacturing and R&D investment may not achieve their intended benefits; 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 anitocabtagene autoleucel, axicabtagene ciloleucel, bictegravir, domvanalimab, lenacapavir, sacituzumab govitecan-hziy, seladelpar, zimberelimab, ABI-1179, ABI-5366, KITE-753 and KITE-363 (such as ALYCANTE, ARTISTRY-1, ARTISTRY-2, ASCENT-07, ASSURE, EDGE-Gastric, iMMagine-1, STAR-221 and ZUMA-7), 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 resolve the issues cited by the FDA in pending clinical holds to the satisfaction of the FDA and the risk that FDA may not remove such clinical holds, in whole or in part, in a timely manner or at all; Gilead’s ability to submit new drug applications for new product candidates or expanded indications in the currently anticipated timelines; 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; Gilead’s ability to effectively manage the access strategy relating to lenacapavir for HIV PrEP, subject to necessary regulatory approvals; 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.
