Product Sales Excluding Veklury Increased 4% Year-Over-Year to $6.9 billion

Biktarvy Sales Increased 9% Year-Over-Year to $3.5 billion

Gilead Sciences, Inc. (Nasdaq: GILD) announced today its second quarter 2025 results of operations.

“This was a very successful second quarter for Gilead, including the FDA approval for Yeztugo as the world’s first twice-yearly HIV prevention option,” said Daniel O’Day, Gilead’s Chairman and Chief Executive Officer. “Our strong growth this quarter was driven by Biktarvy, Descovy, Trodelvy and Livdelzi, reflecting the diversity of our portfolio. As we enter the third quarter, we are increasing revenue and earnings guidance for the year, and look forward to delivering continued innovation and growth across our core therapeutic areas.”

Second Quarter 2025 Financial Results

• Total second quarter 2025 revenue increased 2% to $7.1 billion compared to the same period in 2024, driven by higher HIV, Livdelzi® (seladelpar) and Trodelvy® (sacituzumab govitecan-hziy) sales, partially offset by lower chronic hepatitis C virus (“HCV”) and Veklury® (remdesivir) sales.
• Diluted earnings per share (“EPS”) was $1.56 in the second quarter 2025 compared to $1.29 in the same period in 2024. The increase was primarily driven by net unrealized gains on securities compared to net unrealized losses in 2024 and higher product sales, partially offset by a pre-tax in-process research and development (“IPR&D”) impairment charge of $190 million related to assets acquired as part of the MYR GmbH (“MYR”) acquisition and higher research and development (“R&D”) expenses.
• Non-GAAP diluted EPS of $2.01 in the second quarter 2025 remained flat compared to the same period in 2024, with higher product sales offset by higher R&D expenses.
• As of June 30, 2025, Gilead had $7.1 billion of cash, cash equivalents and marketable debt securities compared to $10.0 billion as of December 31, 2024.
• During the second quarter 2025, Gilead generated $827 million in operating cash flow, net of a final $1.3 billion transition tax payment associated with the Tax Cuts and Jobs Act of 2017.
• During the second quarter 2025, Gilead paid dividends of $994 million and repurchased $527 million of common stock.

Second Quarter 2025 Product Sales

Total second quarter 2025 product sales increased 2% to $7.1 billion compared to the same period in 2024. Total second quarter 2025 product sales excluding Veklury increased 4% to $6.9 billion compared to the same period in 2024, primarily due to higher HIV, Livdelzi and Trodelvy sales, partially offset by lower HCV sales.

HIV product sales increased 7% to $5.1 billion in the second quarter 2025 compared to the same period in 2024, primarily driven by increased demand and higher average realized price.

• Biktarvy® (bictegravir 50mg/emtricitabine (“FTC”) 200mg/tenofovir alafenamide (“TAF”) 25mg) sales increased 9% to $3.5 billion in the second quarter 2025 compared to the same period in 2024, primarily driven by higher demand.
• Descovy® (FTC 200mg/TAF 25mg) sales increased 35% to $653 million in the second quarter 2025 compared to the same period in 2024, primarily driven by higher average realized price and demand.

The Liver Disease portfolio sales decreased 4% to $795 million in the second quarter 2025 compared to the same period in 2024. This was primarily driven by lower HCV sales, partially offset by increased demand for Livdelzi, Hepcludex® (bulevirtide) and chronic hepatitis B virus (“HBV”) products.

Veklury sales decreased 44% to $121 million in the second quarter 2025 compared to the same period in 2024, primarily driven by lower rates of COVID-19-related hospitalizations.

Cell Therapy product sales decreased 7% to $485 million in the second quarter 2025 compared to the same period in 2024, reflecting ongoing competitive headwinds.

• Yescarta® (axicabtagene ciloleucel) sales decreased 5% to $393 million in the second quarter 2025 compared to the same period in 2024, primarily driven by lower demand, partially offset by higher average realized price.
• Tecartus® (brexucabtagene autoleucel) sales decreased 14% to $92 million in the second quarter 2025 compared to the same period in 2024, primarily reflecting lower demand, partially offset by higher average realized price.

Trodelvy sales increased 14% to $364 million in the second quarter 2025 compared to the same period in 2024, primarily driven by higher demand and inventory dynamics.

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

• Product gross margin was 78.7% in the second quarter 2025 compared to 77.7% in the same period in 2024. Non-GAAP product gross margin was 86.9% in the second quarter 2025 compared to 86.0% in the same period in 2024. The increases were primarily driven by product mix.
• R&D expenses were $1.5 billion in the second quarter 2025 compared to $1.4 billion in the same period in 2024, primarily due to increased clinical manufacturing and study expenses, as well as valuation adjustments to the MYR-related contingent consideration. Non-GAAP R&D expenses were $1.5 billion in the second quarter 2025 compared to $1.3 billion in the same period in 2024, primarily due to increased clinical manufacturing and study activities.
• Acquired IPR&D expenses were $61 million in the second quarter 2025, primarily reflecting expenses related to the strategic partnership with Kymera Therapeutics, Inc. (“Kymera”) announced in June 2025.
• Selling, general and administrative (“SG&A”) expenses and non-GAAP SG&A expenses of $1.4 billion in the second quarter 2025 remained flat compared to the same period in 2024, with higher promotional expenses offset by lower corporate expenses.
• The effective tax rate (“ETR”) was 19.3% in the second quarter 2025 compared to 21.4% in the same period in 2024, primarily driven by lower non-taxable unrealized losses on securities, partially offset by a beneficial prior year settlement with a tax authority that did not repeat. The non-GAAP ETR was 18.8% in the second quarter 2025 compared to 17.8% in the same period in 2024, primarily reflecting the same non-recurring tax settlement in the prior year.

Conference Call

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 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 MYR, and the arrangements with Arcellx, Kymera and the Global Fund; 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 Livdelzi, Trodelvy, Yescarta, Yeztugo (lenacapavir), anito-cel, bulevirtide, GS-1720, and GS-4182 (such as the ASCENT-03, ASCENT-04, ASSURE, iMMagine-1, MYR301, PURPOSE 1 PURPOSE 2, WONDERS-1, and WONDERS-2 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 the clinical hold on the GS-1720 and GS-4182 trials to the satisfaction of the FDA and the risk that FDA may not remove the clinical hold, 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; 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 June 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.
