Product Sales Excluding Veklury Increased 11% Year-Over-Year to $6.1 billion

Biktarvy Sales Increased 22% Year-Over-Year to $2.8 billion

Oncology Sales Increased 79% Year-Over-Year to $578 million

Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the third quarter of 2022.

Chairman and Chief Executive Officer of Gilead Sciences, Daniel O’Day said: “This was another very strong quarter across the business. In HIV, treatment and prevention markets continue to grow with further share gains for Biktarvy in treatment, and we received our first approval for our long-acting HIV agent, lenacapavir, in Europe. In oncology, there is increasing demand for cell therapies and Trodelvy. Yescarta and Tecartus received two approvals in Europe and Trodelvy was granted FDA Priority Review for HR+/HER2- metastatic breast cancer. Overall, we are seeing terrific progress from a commercial and clinical perspective and look forward to building on this momentum.”

Third Quarter 2022 Financial Results

• Total third quarter 2022 revenue decreased 5% to $7.0 billion compared to the same period in 2021, primarily due to lower Veklury® (remdesivir) sales, partially offset by increased sales in HIV and oncology products.
• Diluted Earnings Per Share (“EPS”) decreased to $1.42 for the third quarter of 2022 compared to $2.05 for the same period in 2021, mainly driven by higher acquired in-process research and development (“IPR&D”) expenses of $389 million primarily due to the acquisition of MiroBio Ltd. (“MiroBio”) and lower product gross margin and revenues, partially offset by lower income tax expense.
• Non-GAAP diluted EPS decreased to $1.90 for the third quarter of 2022 compared to $2.65 for the same period in 2021, primarily driven by the MiroBio acquisition, as well as lower product gross margin and revenues.
• As of September 30, 2022, Gilead had $6.9 billion of cash, cash equivalents and marketable debt securities down from $7.8 billion as of December 31, 2021.
• During the third quarter of 2022, Gilead generated $2.9 billion in operating cash flow.
• During the third quarter of 2022, Gilead repaid $1.0 billion of debt, made a cash payment of $414 million to acquire MiroBio, paid dividends of $928 million and repurchased $180 million of common stock.

Product Sales Performance

Total third quarter 2022 product sales decreased 5% to $7.0 billion compared to the same period in 2021. Total product sales, excluding Veklury, increased 11% to $6.1 billion in the third quarter of 2022 compared to the same period in 2021, primarily due to increased product sales related to HIV, cell therapy, hepatitis C virus (“HCV”) and Trodelvy® (sacituzumab govitecan-hziy).

HIV product sales increased 7% to $4.5 billion in the third quarter of 2022 compared to the same period in 2021, primarily driven by favorable channel mix associated with government utilization leading to higher average realized price, as well as higher demand.

• Biktarvy® (bictegravir 50mg/emtricitabine 200mg (“FTC”)/tenofovir alafenamide 25mg (“TAF”)) sales increased 22% year-over-year in the third quarter of 2022, primarily due to higher demand and channel mix.
• Descovy® (FTC 200mg/TAF 25mg) sales increased 16% year-over-year in the third quarter of 2022, primarily driven by channel mix and higher demand, partially offset by inventory dynamics.

HCV product sales increased 22% to $524 million in the third quarter of 2022 compared to the same period in 2021, primarily due to a favorable resolution of a prior year rebate claim in Europe and other favorable pricing dynamics in the United States, partially offset by fewer patient starts.

Hepatitis B virus (“HBV”) and hepatitis delta virus (“HDV”) product sales increased 7% to $264 million in the third quarter of 2022 compared to the same period in 2021, primarily driven by Vemlidy® (TAF 25mg). Vemlidy sales increased 10% in the third quarter of 2022 compared to the same period in 2021, primarily driven by favorable inventory dynamics.

Cell therapy product sales increased 79% to $398 million in the third quarter of 2022 compared to the same period in 2021.

• Yescarta® (axicabtagene ciloleucel) sales increased 81% to $317 million in the third quarter of 2022, primarily driven by demand in relapsed or refractory (“R/R”) large B-cell lymphoma (“LBCL”) in the United States and Europe.
• Tecartus® (brexucabtagene autoleucel) sales increased 72% to $81 million in the third quarter of 2022, primarily driven by demand in R/R mantle cell lymphoma (“MCL”) in the United States and Europe as well as in adult R/R B-cell precursor acute lymphoblastic leukemia (“ALL”) in the United States.

Trodelvy sales increased by 78% to $180 million in the third quarter of 2022 compared to the same period in 2021, primarily driven by adoption in both the second- and third-line settings for the treatment of metastatic triple-negative breast cancer.

Veklury sales decreased by 52% to $925 million for the third quarter of 2022 compared to the same period in 2021, primarily driven by lower rates of COVID-19 related hospitalizations compared to the third quarter of 2021. Veklury revenue generally reflects 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 2022 Product Gross Margin, Operating Expenses and Effective Tax Rate

• Product gross margin was 80.0% for the third quarter of 2022 compared to 83.4% for the same period in 2021. Non-GAAP product gross margin was 86.8% for the third quarter of 2022 compared to 90.0% in the same period in 2021. The decreases were primarily driven by a favorable court decision in the third quarter of 2021 that led to the reversal of the previously recorded $175 million litigation reserve during that period, as well as Biktarvy-related royalty expense that began in the first quarter of 2022 and a change in product mix.
• Research and development (“R&D”) expenses for the third quarter of 2022 were $1.1 billion, relatively flat with the same period in 2021. Non-GAAP R&D expenses for the third quarter of 2022 were $1.2 billion, relatively flat with the same period in 2021⁽¹⁾.
• Acquired IPR&D expenses for the third quarter of 2022 were $448 million compared to $65 million⁽¹⁾ in the same period in 2021. The increase primarily reflects an expense of $389 million related to the MiroBio acquisition.
• Selling, general and administrative (“SG&A”) expenses for the third quarter of 2022 were $1.2 billion, relatively flat with the same period in 2021. Non-GAAP SG&A expenses for the third quarter of 2022 were $1.2 billion, relatively flat with the same period in 2021.
• The effective tax rate (“ETR”) for the third quarter of 2022 was 26.6% compared to 24.8% for the same period in 2021. Non-GAAP ETR for the third quarter of 2022 was 22.4% compared to 18.9% for the same period in 2021. The increases in GAAP and Non-GAAP ETR were primarily due to a non-deductible acquired IPR&D charge related to Gilead’s acquisition of MiroBio.

Guidance and Outlook

For the full-year, Gilead has updated its guidance and now expects:

• Total product sales between $25.9 billion and $26.2 billion, compared to $24.5 billion and $25.0 billion previously.
• Total product sales, excluding Veklury, between $22.5 billion to $22.8 billion, compared to $22.0 billion and $22.5 billion previously.
• Total Veklury sales of approximately $3.4 billion, compared to approximately $2.5 billion previously.
• Non-GAAP earnings per share between $6.95 and $7.15, compared to $6.35 and $6.75 previously.
• Earnings per share between $3.35 and $3.55, compared to $2.90 and $3.30 previously.

This financial guidance excludes the impact of any expenses related to potential acquisitions or business development transactions that have not been executed, fair value adjustments of equity securities and discrete tax charges or benefits associated with changes in tax related laws and guidelines as Gilead is unable to project such amounts. A reconciliation between GAAP and non-GAAP financial information for the 2022 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. While the pandemic can be expected to continue to impact Gilead’s business and broader market dynamics, the rate and degree of these impacts as well as the corresponding recovery from the pandemic may vary across Gilead’s business.

Key Updates Since Our Last Quarterly Release

Virology

• Announced the European Commission (“EC”) has granted Marketing Authorization for Sunlenca® (lenacapavir) for the treatment of HIV infection, in combination with other antiretroviral(s), in adults with multi-drug resistant HIV infection for whom it is otherwise not possible to construct a suppressive antiviral regimen.
• Announced that Merck & Co., Inc. (“Merck”) and Gilead plan to resume their Phase 2 study under an amended protocol. The study will evaluate an investigational once-weekly oral combination treatment regimen of Merck’s islatravir at a lower weekly dose and Gilead’s lenacapavir.
• Received a positive opinion from EMA’s Committee for Medicinal Products for Human Use (“CHMP”) to expand the indication of Biktarvy to include pediatric patients with HIV who are at least 2 years of age and weigh at least 14 kg.
• Received a positive opinion from EMA’s CHMP to extend the indication of Veklury for the treatment of pediatric patients under 12 years of age with COVID-19.
• Announced that the World Health Organization has updated its living treatment guideline to conditionally recommend Veklury for the treatment of patients with severe COVID-19 and continues to conditionally recommend Veklury in those with non-severe COVID-19 at the highest risk of hospitalization.
• Demonstrated in vitro antiviral activity of Veklury against Omicron subvariants BA.2.12.1, BA.4 and BA.5, which are currently the most common circulating variants. Results confirm that Veklury retains antiviral activity against all Omicron subvariants analyzed to date.

Oncology

• Presented results of the second interim analysis of the TROPiCS-02 study in patients with pre-treated HR+/HER2- metastatic breast cancer at the European Society for Medical Oncology meeting. The results demonstrated a statistically significant and clinically meaningful improvement in median overall survival (“OS”) as compared to chemotherapy (median OS: 14.4 months vs. 11.2 months; hazard ratio=0.79; 95% confidence interval: 0.65-0.96; p=0.02). Additionally, data from a post hoc subgroup analysis of TROPiCS-02 were presented that showed progression-free survival benefit in patients with HR+/HER2- metastatic breast cancer regardless of their HER2- status, consistent with the study’s intention-to-treat population.
• Announced FDA accepted for Priority Review the supplemental Biologics License Application of Trodelvy for the treatment of patients with pre-treated HR+/HER2- metastatic breast cancer. Trodelvy has not been approved by any regulatory agency for the treatment of HR+/HER2- metastatic breast cancer, and its safety and efficacy have not been established for this indication.
• Announced an agreement to acquire the remaining worldwide development and commercialization rights to Trodelvy from Everest Medicines in Greater China, South Korea and other Asian markets.
• Received European Marketing Authorization for Yescarta use in adults with second-line diffuse large B-cell lymphoma and high-grade B-cell lymphoma. Additionally, the EC granted Marketing Authorization for Tecartus for the treatment of adult R/R ALL, and in Canada, received conditional marketing authorization for Yescarta for R/R follicular lymphoma after two or more lines of systemic therapy.
• Received FDA approval of viral vector manufacturing facility in Oceanside, California.
• Granted Orphan Drug Designation by FDA for KITE-222, an investigational CAR T-cell therapy targeted at C-type lectin-like molecule-1 (CLL-1), for the treatment of acute myeloid leukemia.

Inflammation

• Completed the acquisition of MiroBio for $414 million in cash. MiroBio is a UK-based biotechnology company focused on restoring immune balance with agonists targeting immune inhibitory receptors.

Corporate

• Announced that the company’s Board of Directors declared a quarterly dividend of $0.73 per share of common stock for the fourth quarter of 2022. The dividend is payable on December 29, 2022, to stockholders of record at the close of business on December 15, 2022. Future dividends will be subject to Board approval.

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 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.

Beginning in the first quarter of 2022, consistent with recent industry communications from the U.S. Securities and Exchange Commission (“SEC”), Gilead no longer excludes the initial costs of acquired IPR&D projects from its non-GAAP financial measures. Prior period non-GAAP financial measures are revised to conform to the new presentation.
