Product Sales Excluding Veklury Increased Year-Over-Year by 7% for Full Year 2023 Biktarvy Sales Increased Year-Over-Year by 14% for Full Year 2023 Oncology Sales Increased Year-Over-Year by 37% for Full Year 2023 FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the fourth quarter and full year 2023. “This was another strong year of revenue growth for Gilead’s base business, driven by both HIV and Oncology,” said Daniel O’Day, Gilead’s Chairman and Chief Executive Officer. “The strength of the business provides a solid foundation as we enter a new catalyst-rich phase for the company. We are expecting several milestones in 2024, including updates on long-acting HIV prevention and treatment, Cell Therapy and Trodelvy.” Fourth Quarter 2023 Financial Results Total fourth quarter 2023 revenue decreased 4% to $7.1 billion compared to the same period in 2022, primarily due to lower Veklury® (remdesivir) and HIV sales, partially offset by higher Oncology sales. Diluted Earnings Per Share (“EPS”) decreased to $1.14 in the fourth quarter 2023 compared to $1.30 in the same period in 2022, primarily due to higher total costs and expenses, and lower Veklury revenues, partially offset by unrealized gains on equity investments in 2023 compared to losses in 2022, and lower tax expense. Non-GAAP diluted EPS increased to $1.72 in the fourth quarter 2023 compared to $1.67 in the same period in 2022, primarily due to lower total costs and expenses, partially offset by lower Veklury revenues. As of December 31, 2023, Gilead had $8.4 billion of cash, cash equivalents and marketable debt securities compared to $7.6 billion as of December 31, 2022. During the fourth quarter 2023, Gilead generated $2.2 billion in operating cash flow. During the fourth quarter 2023, Gilead paid cash dividends of $943 million and utilized $150 million to repurchase common stock. Fourth Quarter 2023 Product Sales Total fourth quarter 2023 product sales decreased 4% to $7.1 billion compared to the same period in 2022. Total product sales, excluding Veklury, of $6.3 billion were flat compared to the same period in 2022, with higher Oncology sales partially offset by lower HIV sales. HIV product sales decreased 2% to $4.7 billion in the fourth quarter 2023 compared to the same period in 2022, primarily driven by lower average realized price due to channel mix, partially offset by higher demand and channel inventory dynamics. Biktarvy® (bictegravir 50mg/emtricitabine (“FTC”) 200mg/tenofovir alafenamide (“TAF”) 25mg) sales increased 7% to $3.1 billion in the fourth quarter 2023 compared to the same period in 2022, primarily reflecting higher demand, partially offset by lower average realized price due to channel mix. Descovy® (FTC 200mg/TAF 25mg) sales decreased 5% to $509 million in the fourth quarter 2023 compared to the same period in 2022, primarily driven by unfavorable pricing dynamics in the United States, partially offset by higher demand and channel inventory dynamics. The Liver Disease portfolio sales were $691 million in the fourth quarter 2023 and remained flat compared to the same period in 2022. Sales were impacted by unfavorable pricing dynamics, offset by higher demand across chronic hepatitis C virus (“HCV”) and chronic hepatitis delta virus (“HDV”) products. Cell Therapy product sales increased 11% to $466 million in the fourth quarter 2023 compared to the same period in 2022. Yescarta® (axicabtagene ciloleucel) sales increased 9% to $368 million in the fourth quarter 2023 compared to the same period in 2022, primarily driven by strong demand in relapsed or refractory (“R/R”) large B-cell lymphoma (“LBCL”) outside the United States. Tecartus® (brexucabtagene autoleucel) sales increased 19% to $98 million in the fourth quarter 2023 compared to the same period in 2022, driven by increased demand in R/R adult acute lymphoblastic leukemia (“ALL”) and in R/R mantle cell lymphoma (“MCL”). Trodelvy® (sacituzumab govitecan-hziy) sales increased 53% to $299 million in the fourth quarter 2023 compared to the same period in 2022, reflecting higher demand in both the United States and Europe. Veklury sales decreased 28% to $720 million in the fourth quarter 2023 compared to the same period in 2022, primarily driven by lower rates of COVID-19 related hospitalizations. Veklury sales generally reflect COVID-19 related rates and severity of infections and hospitalizations, as well as the availability, uptake and effectiveness of vaccinations and alternative treatments for COVID-19. Fourth Quarter 2023 Product Gross Margin, Operating Expenses and Tax Product gross margin was 70.4% in the fourth quarter 2023 compared to 81.0% in the same period in 2022, primarily driven by restructuring expenses related to changes in our manufacturing strategy, intangible asset amortization expenses related to Trodelvy following approval for pretreated HR+/HER2- metastatic breast cancer in February 2023, and product mix. Non-GAAP product gross margin was 86.1% in the fourth quarter 2023 compared to 86.8% in the same period in 2022, primarily driven by product mix. Research and development (“R&D”) expenses were $1.4 billion in the fourth quarter 2023 compared to $1.5 billion in the same period in 2022, driven by the timing of clinical activities and valuation adjustments to the MYR-related contingent consideration, partially offset by increased investments in Oncology. Non-GAAP R&D expenses were $1.5 billion in the fourth quarter 2023 and in the same period in 2022. Decreases due to the timing of clinical activities were offset by increased investments in Oncology. Acquired in-process research and development (“IPR&D”) expenses were $347 million in the fourth quarter 2023, primarily driven by payments related to collaborations with Arcellx, Inc. (“Arcellx”), Assembly Biosciences, Inc. (“Assembly”), and Compugen Ltd. (“Compugen”), as well as a milestone payment related to the acquisition of XinThera, Inc. (“XinThera”). Selling, general and administrative (“SG&A”) and non-GAAP SG&A expenses were $1.6 billion in the fourth quarter 2023 compared to $2.0 billion in the same period in 2022. The decrease was primarily driven by a 2022 charge related to the termination of the Trodelvy collaboration agreement with Everest Medicines (“Everest”) that did not repeat. The effective tax rate (“ETR”) was 14.3% in the fourth quarter 2023 compared to 19.6% in the same period in 2022, primarily due to remeasurement of certain deferred tax liabilities and non-taxable unrealized gains on equity investments. Non-GAAP ETR was 17.1% in the fourth quarter 2023 compared to 16.8% in the same period in 2022. Full Year 2023 Financial Results Total full year 2023 revenue decreased 1% to $27.1 billion compared to 2022, driven by a reduction of $1.7 billion in Veklury sales, largely offset by higher HIV and Oncology sales. Diluted EPS increased to $4.50 in the full year 2023 compared to $3.64 in 2022, primarily due to lower IPR&D impairment expenses, lower unrealized losses on equity investments, and higher interest income, partially offset by higher cost of goods sold and operating expenses, and lower Veklury sales. Non-GAAP diluted EPS decreased to $6.72 in the full year 2023 compared to $7.26 in 2022. This was primarily driven by higher total costs and expenses, as well as lower Veklury sales, partially offset by a decrease in tax reserves as a result of reaching an agreement with a tax authority, and higher interest income. Full Year 2023 Product Sales Total full year 2023 product sales of $26.9 billion were relatively flat compared to the same period in 2022, with lower Veklury sales largely offset by higher HIV and Oncology sales. Total product sales, excluding Veklury, increased 7% to $24.7 billion in the full year 2023 compared to 2022, primarily driven by higher HIV and Oncology sales. HIV product sales increased 6% to $18.2 billion in the full year 2023 compared to 2022, primarily reflecting higher demand across treatment and prevention, in addition to higher average realized price and favorable channel inventory dynamics. Biktarvy sales increased 14% to $11.8 billion in the full year 2023 compared to 2022, primarily reflecting higher demand as well as higher average realized price. Descovy sales increased 6% to $2.0 billion in the full year 2023 compared to 2022, primarily driven by favorable channel inventory dynamics and higher demand. The Liver Disease portfolio sales decreased 1% to $2.8 billion in the full year 2023 compared to 2022. The decrease was primarily driven by unfavorable HCV pricing dynamics and foreign exchange rates, partially offset by higher demand across HCV, HDV and chronic hepatitis B virus (“HBV”) products. Cell Therapy product sales increased 28% to $1.9 billion in the full year 2023 compared to 2022. Yescarta sales increased 29% to $1.5 billion in the full year 2023 compared to 2022, primarily driven by increased demand in R/R LBCL. Tecartus sales increased 24% to $370 million in the full year 2023 compared to 2022, primarily driven by increased demand in in R/R ALL and R/R MCL. Trodelvy sales increased 56% to $1.1 billion in the full year 2023 compared to 2022, reflecting strong demand in new and existing geographies. Veklury sales decreased 44% to $2.2 billion in the full year 2023 compared to 2022, primarily driven by lower rates of COVID-19 related hospitalizations in all regions. Full Year 2023 Product Gross Margin, Operating Expenses and Tax Product gross margin was 75.9% in the full year 2023 compared to 79.0% in 2022, primarily driven by restructuring expenses related to the aforementioned changes in our manufacturing strategy, increased amortization expenses, and product mix. Non-GAAP product gross margin was 86.3% in the full year 2023 compared to 86.6% in 2022, primarily driven by product mix. R&D and non-GAAP R&D expenses were $5.7 billion in the full year 2023 compared to $5.0 billion in 2022. This primarily reflects increased clinical activities across our Oncology and Virology programs. Acquired IPR&D expenses were $1.2 billion in the full year 2023, primarily driven by payments related to the collaboration with Arcellx, as well as the acquisition of XinThera and Tmunity Therapeutics Inc. (“Tmunity”). SG&A expenses were $6.1 billion in the full year 2023 compared to $5.7 billion in 2022. Non-GAAP SG&A expenses were $6.1 billion in the full year 2023 compared to $5.6 billion in 2022. The increases in SG&A and non-GAAP SG&A expenses are primarily due to a $525 million litigation settlement with certain plaintiffs in the HIV antitrust litigation and increased commercial activities in Oncology and HIV, partially offset by the 2022 charge related to the termination of the Trodelvy collaboration agreement with Everest. The ETR and non-GAAP ETR were 18.2% and 15.2%, respectively, in the full year 2023 compared to 21.5% and 19.3%, respectively, in 2022. Lower ETR is primarily due to a decrease in tax reserves as a result of reaching agreement with a tax authority on certain tax positions. Guidance and Outlook Gilead is providing full-year 2024 guidance below: Total product sales between $27.1 billion and $27.5 billion. Total product sales, excluding Veklury, between $25.8 billion and $26.2 billion. Total Veklury sales of approximately $1.3 billion. Diluted EPS between $5.15 and $5.55. Non-GAAP diluted EPS between $6.85 and $7.25. Additional information and a reconciliation between GAAP and non-GAAP financial information for the 2024 guidance is provided in the accompanying tables. The financial guidance is subject to a number of risks and uncertainties. See the Forward-Looking Statements section below. Key Updates Since Our Last Quarterly Release Virology Announced that the Phase 3 OAKTREE trial of obeldesivir in non-hospitalized participants without risk factors for developing severe COVID-19 did not meet its primary endpoint of improvement in time to symptom alleviation. Obeldesivir was well-tolerated in this large study population. Oncology Announced that the Phase 3 EVOKE-01 study of Trodelvy versus docetaxel in previously treated metastatic non-small cell lung cancer did not meet its primary endpoint of overall survival. While not statistically powered, we observed an encouraging trend in a subgroup of patients non-responsive to prior anti-PD-(L)1 immunotherapy, that we may potentially explore further. Presented new data at the San Antonio Breast Cancer Symposium 2023, including a post-hoc, subgroup analysis of clinical outcomes by age from the Phase 3 TROPiCS-02 study of Trodelvy in HR+/HER2- metastatic breast cancer. Presented new data at the American Society of Hematology 2023 Annual Meeting (“ASH”) including long-term follow-up across Yescarta trials in R/R LBCL, first-line high-risk LBCL, and R/R follicular lymphoma, as well as real-world data for Tecartus in R/R MCL and B-cell ALL. Received U.S. Food and Drug Administration (“FDA”) approval of Yescarta’s label update to include overall survival (“OS”) data from the Phase 3 ZUMA-7 study, which showed a statistically significant OS improvement for Yescarta in second-line R/R LBCL versus standard of care. Received FDA approval of a manufacturing process change resulting in reduced median turnaround time for Yescarta in the U.S. to an anticipated 14 days (from 16 days previously). Our partner Arcellx presented updated data at ASH from the Phase 1 trial evaluating anitocabtagene autoleucel (“anito-cel”) in R/R multiple myeloma. With 26.5 months of median follow-up, the data demonstrated continued deep and durable responses, including in patients with extramedullary disease, with median progression-free survival not reached. In addition, no cases of delayed neurotoxicity events or parkinsonian symptoms were observed. Announced expansion of the Arcellx collaboration to include exercising an option for the ARC-SparX ACLX-001 program in multiple myeloma, expanding the scope of the existing anito-cel collaboration to include lymphomas, and a further equity investment of $200 million. Announced an amended collaboration agreement with Arcus Biosciences, Inc. (“Arcus”), including an update to the domvanalimab development collaboration program, and an additional $320 million equity investment. Announced an exclusive license agreement with Compugen for later-stage development and commercialization of novel pre-clinical anti-IL18 binding protein antibodies, including COM503, that have the potential to treat various tumor types. Corporate Announced that Ted Love has joined Gilead’s Board of Directors. Named to Dow Jones Sustainability World Index for third consecutive year and added to the North America Index for the first year, reflecting Gilead’s ongoing commitment to corporate responsibility and sustainability. The company’s Board of Directors declared a quarterly dividend of $0.77 per share of common stock for the first quarter of 2024. The dividend is payable on March 28, 2024, to stockholders of record at the close of business on March 15, 2024. Future dividends will be subject to Board approval. Certain amounts and percentages in this press release may not sum or recalculate due to rounding. Conference Call At 2:00 p.m. Pacific Time today, Gilead will host a conference call to discuss Gilead’s results. A live webcast will be available on and will be archived on 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 inventory step-up charges, 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 changes in tax related laws and guidelines. 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 anticipated full year 2024 financial results, 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 strategic 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, Arcus, Assembly, Compugen, Galapagos NV, MYR, Tmunity, and XinThera; 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 Tecartus, Trodelvy (including EVOKE-01), Yescarta, anito-cel and domvanalimab, 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; Gilead’s ability to receive 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; 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 these products over other therapies and may therefore be reluctant to prescribe the products, including Yescarta; 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.

Product Sales Excluding Veklury Increased 5% Year-Over-Year to $6.4 billion Biktarvy Sales Increased 12% Year-Over-Year to $3.1 billion Oncology Sales Increased 33% Year-Over-Year to $769 million FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc., (Nasdaq: GILD) announced today its results of operations for the third quarter of 2023. “Gilead has now delivered two years of consistent growth in our base business. In the third quarter, this continued growth was driven by both Virology and Oncology,” said Daniel O’Day, Gilead's Chairman and Chief Executive Officer. “Our clinical momentum also remains strong, and highlights this quarter included new data on Trodelvy with pembrolizumab in first-line metastatic non-small cell lung cancer. In Virology, we completed enrollment for Phase 3 trials of lenacapavir for HIV prevention and oral obeldesivir for COVID-19. We are looking forward to advancing these and other potential new options for patients over the coming months.” Third Quarter 2023 Financial Results Total third quarter 2023 revenue of $7.1 billion was flat compared to the same period in 2022, primarily driven by increased sales in Oncology and HIV, offset by lower Veklury® (remdesivir) and chronic hepatitis C virus (“HCV”) product sales. Diluted Earnings Per Share (“EPS”) increased to $1.73 for the third quarter of 2023 compared to $1.42 for the same period in 2022, and non-GAAP diluted EPS increased to $2.29 for the third quarter of 2023 compared to $1.90 for the same period in 2022. The increases in GAAP and non-GAAP diluted EPS were primarily driven by lower tax expense, partially offset by net higher total costs and expenses. As of September 30, 2023, Gilead had $8.0 billion of cash, cash equivalents and marketable debt securities, up from $7.6 billion as of December 31, 2022. During the third quarter of 2023, Gilead generated $1.8 billion in operating cash flow. During the third quarter of 2023, Gilead repaid $2.3 billion of debt, paid dividends of $953 million and repurchased $300 million of common stock. Additionally, Gilead issued senior unsecured notes in an aggregate principal amount of $2.0 billion. Product Sales Performance Total third quarter 2023 product sales of $7.0 billion was flat compared to the same period in 2022, reflecting continued growth in the base business, offset by lower Veklury sales. Total product sales, excluding Veklury, increased 5% to $6.4 billion in the third quarter of 2023 compared to the same period in 2022, primarily due to increased sales in Oncology and HIV, partially offset by lower HCV sales. HIV product sales increased 4% to $4.7 billion in the third quarter of 2023 compared to the same period in 2022, primarily driven by higher demand and channel inventory dynamics, partially offset by lower average realized price due to a shift in channel mix. Biktarvy® (bictegravir 50mg/emtricitabine 200mg (“FTC”)/tenofovir alafenamide 25mg (“TAF”)) sales increased 12% year-over-year in the third quarter of 2023, primarily driven by higher demand, as well as favorable channel inventory. Descovy® (FTC 200mg/TAF 25mg) sales increased 2% year-over-year in the third quarter of 2023, primarily driven by higher demand, partially offset by pricing dynamics in the United States. The Liver Disease portfolio sales, which includes HCV, chronic hepatitis B virus (“HBV”), and chronic hepatitis delta virus (“HDV”), decreased 10% to $706 million in the third quarter of 2023 compared to the same period in 2022, as higher HCV patient starts were more than offset by unfavorable pricing dynamics, primarily due to the resolution of a rebate claim in HCV in the third quarter of 2022. Cell Therapy product sales increased 22% to $486 million in the third quarter of 2023 compared to the same period in 2022. Yescarta® (axicabtagene ciloleucel) sales increased 23% year-over-year to $391 million in the third quarter of 2023, primarily driven by strong demand in the second- and third-line settings for relapsed or refractory (“R/R”) large B-cell lymphoma (“LBCL”) outside of the United States. Tecartus® (brexucabtagene autoleucel) sales increased 18% year-over-year to $96 million in the third quarter of 2023, primarily driven by increased demand in R/R mantle cell lymphoma (“MCL”) and R/R adult acute lymphoblastic leukemia (“ALL”). Trodelvy® (sacituzumab govitecan-hziy) sales increased 58% to $283 million in the third quarter of 2023 compared to the same period in 2022, primarily driven by higher demand in both the United States and Europe. Veklury sales decreased 31% to $636 million for the third quarter of 2023 compared to the same period in 2022, primarily driven by lower rates of COVID-19 related hospitalizations in all regions. Veklury sales generally reflect COVID-19 related rates and severity of infections and hospitalizations, as well as the availability, uptake and effectiveness of vaccinations and alternative treatments for COVID-19. Third Quarter 2023 Product Gross Margin, Operating Expenses and Effective Tax Rate Product gross margin was 77.6% for the third quarter of 2023 compared to 80.0% for the same period in 2022, primarily driven by intangible asset amortization expenses related to the pretreated HR+/HER2- metastatic breast cancer indication for Trodelvy following its approval in February 2023, as well as product mix. Non-GAAP product gross margin was 85.9% for the third quarter of 2023 compared to 86.8% in the same period in 2022, primarily driven by product mix. Research & development (“R&D”) expenses for the third quarter of 2023 were $1.5 billion compared to $1.1 billion in the same period in 2022. Non-GAAP R&D expenses for the third quarter of 2023 were $1.5 billion compared to $1.2 billion in the same period in 2022. The increases in GAAP and non-GAAP R&D expenses were primarily driven by increased clinical activity, as well as costs associated with the discontinuation of two Phase 3 magrolimab studies. Acquired in-process research and development (“IPR&D”) expenses for the third quarter of 2023 were $91 million, driven by an upfront payment related to the Tentarix Biotherapeutics Inc. (“Tentarix”) collaboration and other collaboration-related activities. Selling, general and administrative (“SG&A”) expenses and non-GAAP SG&A expenses for the third quarter of 2023 were $1.3 billion compared to $1.2 billion in the same period in 2022. The increases in GAAP and non-GAAP SG&A expenses were primarily driven by increased commercial activities in Oncology. The effective tax rate (“ETR”) for the third quarter of 2023 was 6.3% compared to 26.6% for the same period in 2022, and non-GAAP ETR for the third quarter of 2023 was 7.0% compared to 22.4% for the same period in 2022. Both ETR and non-GAAP ETR decreases were primarily driven by a decrease in tax reserves as a result of reaching agreement with a tax authority on certain tax positions. Guidance and Outlook For the full-year, Gilead expects: Total product sales between $26.7 billion and $26.9 billion, compared to $26.3 billion and $26.7 billion previously. Total product sales, excluding Veklury, between $24.8 billion and $25.0 billion, compared to $24.6 billion and $25.0 billion previously. Total Veklury sales of approximately $1.9 billion, compared to approximately $1.7 billion previously. Diluted earnings per share between $4.55 and $4.75, compared to $4.50 and $4.85 previously. Non-GAAP diluted earnings per share between $6.65 and $6.85, compared to $6.45 and $6.80 previously. Additional information and a reconciliation between GAAP and non-GAAP financial information for the 2023 guidance is provided in the accompanying tables. Also see the Forward-Looking Statements described below. The financial guidance is subject to a number of risks and uncertainties, including uncertainty around the duration and magnitude of the COVID-19 pandemic. Key Updates Since Our Last Quarterly Release Virology Received U.S. Food and Drug Administration (“FDA”) and European Commission approval to extend the use of Veklury to treat COVID-19 in appropriate patients with mild to severe hepatic impairment. Presented new data at the European AIDS Conference 2023, including three-year outcomes from BICSTaR, an ongoing real-world study evaluating Biktarvy in people with HIV who have a high burden of co-morbidities, and multiple analyses from the Phase 2/3 CAPELLA study of lenacapavir in people with multi-drug resistant HIV. Announced PURPOSE 5, a Phase 2 clinical trial to assess the persistence of lenacapavir compared with FTC/tenofovir disoproxil fumarate in people who may benefit from PrEP in Europe. The use of lenacapavir for PrEP is investigational. Presented new data at Infectious Disease Week 2023 demonstrating Biktarvy’s efficacy and safety pro a broad range of people with HIV as well as two-year outcomes from the CAPELLA study of lenacapavir. Additionally, presented data on the safety pro Veklury across vulnerable populations and the drug-drug interaction pro the investigational oral antiviral obeldesivir, as well as new in vitro data on antiviral activity of Veklury and obeldesivir against recent SARS-CoV-2 Omicron subvariants. Discontinued the Phase 3 BIRCH trial of obeldesivir in non-hospitalized participants who are at high risk for developing severe COVID-19. The decision was based on lower-than-expected COVID-19 incidence rates and related hospitalizations or all-cause death by Day 29, and does not reflect any safety or efficacy concerns. Announced the Phase 3 OAKTREE trial of obeldesivir in non-hospitalized participants without risk factors for developing severe COVID-19 is approaching full enrollment, and remains unaffected by the BIRCH decision. Announced plans to present at the American Association for the Study of Liver Diseases 2023 annual meeting. Presentations will include new and long-term data across Gilead’s Liver Disease portfolio. Announced a collaboration with Assembly Biosciences, Inc. (“Assembly”) to advance the research and development of novel antiviral therapies, including in herpesviruses, HBV and HDV. Oncology Presented promising early data at the 2023 World Conference on Lung Cancer from the Phase 2 EVOKE-02 study evaluating the investigational use of Trodelvy in combination with Keytruda® (pembrolizumab) as a first-line treatment in patients with advanced or metastatic non-small cell lung cancer without actionable genomic alterations. The study demonstrated clinical activity in patients with PD-L1 tumor proportion score (“TPS”) >50% in Cohort A and PD-L1 TPS<50% in Cohort B, including early and durable responses, as well as safety consistent with the known safety pro each agent. Presented data at the European Society of Medical Oncology 2023 meeting from the Phase 2 TROPiCS-03 basket study demonstrating encouraging activity of Trodelvy for investigational use in both advanced head and neck squamous cell carcinoma and extensive stage small cell lung cancer cohorts, as well as other data in breast and urothelial cancer. Additionally, presented a comparative analysis, adjusting for trial differences, on Yescarta relative to bispecific antibodies in 3L+ R/R LBCL. Announced abstracts for the American Society of Hematology 2023 Annual Meeting, including updated Phase 1 data evaluating the Arcellx, Inc. (“Arcellx”) partnered CART-ddBCMA in R/R multiple myeloma, demonstrating continued deep and durable responses with 22 months follow-up. Additionally announced abstracts for long-term follow-up across Yescarta trials in R/R LBCL, first-line high-risk LBCL, and R/R follicular lymphoma, as well as real-world data for Tecartus in R/R MCL and B-cell ALL. Announced results from the Phase 2 ALYCANTE study, led and sponsored by the French collaborative group LYSA/LYSARC, evaluating Yescarta in transplant-ineligible patients with second-line R/R LBCL, which demonstrated high response rates and durable remission. Presented initial data, alongside Arcus Biosciences, Inc. (“Arcus”) at the American Society of Clinical Oncology Monthly Plenary Session from the Phase 2 EDGE-Gastric study of domvanalimab in combination with zimberelimab and chemotherapy in first-line locally advanced unresectable or metastatic gastric, gastroesophageal junction, or esophageal adenocarcinoma. The results showed encouraging overall response rates and six-month landmark progression-free survival rate. Discontinued the Phase 3 ENHANCE-2 study of magrolimab in first-line acute myeloid leukemia (“AML”) with TP53 mutations based on an ad hoc analysis and following review by an independent data monitoring committee. Additionally announced that the U.S. FDA placed a partial clinical hold on magrolimab studies in AML that paused enrollment, though previously enrolled patients may continue to receive the study medicine. Announced a collaboration with Tentarix to discover and develop novel therapies across oncology and inflammation, using Tentarix’s proprietary Tentacles platform. Announced a collaboration with Epicrispr Biotechnologies, Inc. (“Epic Bio”) to develop next-generation cancer cell therapies using Epic Bio’s proprietary gene regulation platform. Corporate Issued $2.0 billion aggregate principal amount of senior unsecured notes in a registered offering, comprised of $1.0 billion principal amount of 5.25% senior notes due in 2033 and $1.0 billion principal amount of 5.55% senior notes due in 2053, and repaid debt of $2.3 billion. The company’s Board of Directors declared a quarterly dividend of $0.75 per share of common stock for the fourth quarter of 2023. The dividend is payable on December 28, 2023, to stockholders of record at the close of business on December 15, 2023. Future dividends will be subject to Board approval.

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 inventory step-up charges, 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 changes in tax related laws and guidelines. 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 anticipated full year 2023 financial results, 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 strategic 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 Arcus, Arcellx, Assembly, Epic Bio, and Tentarix; 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, Veklury, Yescarta, CART-ddBCMA, domvanalimab, lenacapavir, magrolimab, obeldesivir, and zimberelimab, 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; Gilead’s ability to receive 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; 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 these products over other therapies and may therefore be reluctant to prescribe the products, including Veklury; 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, 2023 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.
