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

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.

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.
