Item 2.02     Results of Operations and Financial Condition.

On October 30, 2025, Gilead Sciences, Inc., a Delaware corporation (“Gilead”), announced its financial results for the quarter ended September 30, 2025. A copy of the press release is filed as Exhibit 99.1 to this report.

Gilead has presented certain financial information in accordance with U.S. generally accepted accounting principles (“GAAP”) and also on a non-GAAP basis.

Non-GAAP measures may be defined and calculated differently by other companies in the same industry. A reconciliation between GAAP and non-GAAP financial information is provided in the tables on pages 9, 10 and 11 of the press release filed as Exhibit99.1 to this report.

The information in Item 2.02 and Item 9.01 of this Form 8-K and Exhibit 99.1 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities under that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing.

GILEAD SCIENCES ANNOUNCES THIRD QUARTER 2025 FINANCIAL RESULTS

Product Sales Excluding Veklury Increased 4% Year-Over-Year to $7.1 billion

Biktarvy Sales Increased 6% Year-Over-Year to $3.7 billion

Foster City, CA, October 30, 2025 - Gilead Sciences, Inc. (Nasdaq: GILD) announced today its third quarter 2025 results of operations.

“We continue to deliver on Gilead's robust portfolio with a strong start for Yeztugo, rapidly growing uptake of Biktarvy, Descovy and Livdelzi, and positive data for Trodelvy in 1L metastatic triple negative breast cancer,” said Daniel O’Day, Gilead’s Chairman and Chief Executive Officer.  “With multiple potential product launches in 2026, the strongest clinical pipeline in Gilead’s history, and no major loss of exclusivity expected until 2036, we are well-positioned to drive positive impact for patients and continued growth of our business.”

Third Quarter 2025 Financial Results

•Total third quarter 2025 revenues increased 3% to $7.8 billion compared to the same period in 2024, broken down as follows:

◦Total third quarter 2025 product sales decreased 2% to $7.3 billion compared to the same period in 2024, primarily driven by lower Veklury® (remdesivir) and Cell Therapy sales, partially offset by higher HIV and Livdelzi® (seladelpar) sales.

◦Total third quarter 2025 royalty, contract and other revenues increased by approximately $400 million compared to the same period in 2024, primarily driven by revenue related to a previous sale of intellectual property not expected to reoccur.

•Diluted earnings per share (“EPS”) was $2.43 in the third quarter 2025 compared to $1.00 in the same period in 2024. The increase was primarily driven by a prior year pre-tax in-process research and development (“IPR&D”) impairment charge of $1.75 billion that did not repeat in the current period, as well as the $400 million increase in other revenue mentioned above, lower acquired IPR&D expenses and higher net unrealized gains on equity investments in the current period, partially offset by higher tax expense.

•Non-GAAP diluted EPS of $2.47 in the third quarter 2025 compared to $2.02 in the same period in 2024. The increase was primarily driven by the $400 million increase in other revenue mentioned above and lower acquired IPR&D expenses.

•As of September 30, 2025, Gilead had $9.4 billion of cash, cash equivalents and marketable debt securities compared to $10.0 billion as of December 31, 2024.

•During the third quarter 2025, Gilead generated $4.1 billion in operating cash flow.

•During the third quarter 2025, Gilead paid dividends of $1.0 billion and repurchased $435 million of common stock.

Third Quarter 2025 Product Sales

Total third quarter 2025 product sales decreased 2% to $7.3 billion compared to the same period in 2024. Total third quarter 2025 product sales excluding Veklury increased 4% to $7.1 billion compared to the same period in 2024, primarily due to higher HIV and Livdelzi sales, partially offset by lower Cell Therapy sales.

October 30, 2025 2

HIV product sales increased 4% to $5.3 billion in the third 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.

•Biktarvy® (bictegravir 50mg/emtricitabine (“FTC”) 200mg/tenofovir alafenamide (“TAF”) 25mg) sales increased 6% to $3.7 billion in the third 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 20% to $701 million in the third quarter 2025 compared to the same period in 2024, primarily driven by higher demand.

The Liver Disease portfolio sales increased 12% to $819 million in the third quarter 2025 compared to the same period in 2024, primarily driven by higher demand for Livdelzi.

Veklury sales decreased 60% to $277 million in the third quarter 2025 compared to the same period in 2024, primarily driven by lower rates of COVID-19-related hospitalizations.

Cell Therapy product sales decreased 11% to $432 million in the third quarter 2025 compared to the same period in 2024, reflecting ongoing competitive headwinds.

•Yescarta® (axicabtagene ciloleucel) sales decreased 10% to $349 million in the third quarter 2025 compared to the same period in 2024, primarily driven by lower demand.

•Tecartus® (brexucabtagene autoleucel) sales decreased 15% to $83 million in the third quarter 2025 compared to the same period in 2024, primarily reflecting lower demand.

Trodelvy® (sacituzumab govitecan-hziy) sales increased 7% to $357 million in the third quarter 2025 compared to the same period in 2024, primarily driven by higher demand.

Third Quarter 2025 Product Gross Margin, Operating Expenses and Effective Tax Rate

•Product gross margin remained relatively flat at 78.6% in the third quarter 2025 compared to 79.1% in the same period in 2024. Non-GAAP product gross margin also remained relatively flat at 86.5% in the third quarter 2025 compared to 86.8% in the same period in 2024.

•Research and development (“R&D”) expenses and non-GAAP R&D expenses were $1.3 billion in the third quarter 2025 compared to $1.4 billion in the same period in 2024, decreasing primarily due to lower study-related and clinical manufacturing expenses.

•Acquired IPR&D expenses were $170 million in the third quarter 2025, primarily related to a $120 million upfront payment related to our collaboration with Shenzhen Pregene Biopharma Co., Ltd. (“Pregene”).

•Selling, general and administrative (“SG&A”) expenses and non-GAAP SG&A expenses of $1.4 billion in the third quarter 2025 remained relatively flat compared to the same period in 2024, with lower corporate expenses being largely offset by higher HIV promotional expenses.

•The effective tax rate (“ETR”) was 16.2% in the third quarter 2025 compared to (31.1)% in the same period in 2024, primarily driven by the prior year impact of a legal entity restructuring and the aforementioned IPR&D impairment charge that did not repeat in the current period. The non-GAAP ETR was 17.5% in both the third quarter 2025 and the same period in 2024.

•Presented overall survival results at ESMO from Arm A1 of the Phase 2 EDGE-Gastric study evaluating combination treatment of the Fc-silent anti-TIGIT domvanalimab plus the anti-PD-1 zimberelimab and chemo in people with advanced gastric or esophageal cancer that has spread or cannot be removed with surgery.

Conference Call

At 1:30 p.m. Pacific Time today, Gilead will host a conference call to discuss Gilead’s results. A live webcast will be available on http://investors.gilead.com and will be archived on www.gilead.com for one year.

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 Interius, and the arrangements with Pregene and PEPFAR; 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, including with respect to Biktarvy; 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

October 30, 2025 5

involving Trodelvy, domvanalimab and zimberelimab (such as the ASCENT-03, and EDGE-Gastric 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 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, including for additional approvals for lenacapavir for HIV 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 Yeztugo/Yeytuo; 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. 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 September 30, 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. Gilead claims the protection of the Safe Harbor contained in the Private Securities Litigation Reform Act of 1995 for forward-looking statements.

The reader is cautioned that forward-looking statements are not guarantees of future performance and is cautioned not to place undue reliance on these forward-looking statements. All forward-looking statements are based on information currently available to Gilead and Gilead assumes no obligation to update or supplement any such forward-looking statements other than as required by law. Any forward-looking statements speak only as of the date hereof or as of the dates indicated in the statements.

Additional information is available on our Investor Relations website, https://investors.gilead.com. Among other things, an estimate of Acquired IPR&D expenses is expected to be made available on the Quarterly Results page within the first ten (10) days after the end of each quarter.

The non-GAAP full-year guidance includes non-GAAP adjustments to actual current period results as well as adjustments for the known future impact associated with events that have already occurred, such as future amortization of our intangible assets and the future impact of discrete and related deferred tax charges or benefits primarily associated with acquired intangible assets and in-process research and development, transfers of intangible assets from a foreign subsidiary to Ireland and the United States, and legal entity restructurings.
