Product Sales Excluding Veklury Increased 11% Year-Over-Year to $6.3 billion

Biktarvy Sales Increased 17% Year-Over-Year to $3.0 billion

Oncology Sales Increased 38% Year-Over-Year to $728 million

Net Income Reflects $525 million Legal Settlement Accrual ($0.32 per share)

Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the second quarter of 2023.

“It was another strong quarter for Gilead, with continued commercial and clinical momentum,” said Daniel O’Day, Gilead's Chairman and Chief Executive Officer. “11% year-over-year growth across our base business was driven by our diverse portfolio of therapies for HIV, Oncology, and Liver Disease. We received positive regulatory updates for six of our therapies and presented a large body of data on our pipeline, reinforcing our growing potential to help more patients and communities worldwide.”

Second Quarter 2023 Financial Results

• Total second quarter 2023 revenue increased 5% to $6.6 billion compared to the same period in 2022, primarily driven by increased sales in HIV and Oncology, partially offset by lower Veklury® (remdesivir) sales.
• Diluted Earnings Per Share (“EPS”) decreased to $0.83 for the second quarter of 2023 compared to $0.91 for the same period in 2022, mainly driven by a $525 million litigation accrual for settlements with certain plaintiffs in the HIV antitrust litigation, representing an unfavorable $0.32 impact to diluted EPS, as well as other higher operating costs and tax expense, partially offset by higher product revenues and unrealized gains on equity investments compared to unrealized losses in 2022.
• Non-GAAP diluted EPS decreased to $1.34 for the second quarter of 2023 compared to $1.58 for the same period in 2022, primarily driven by the litigation accrual referenced earlier, representing an unfavorable $0.32 impact to non-GAAP diluted EPS, as well as other higher operating costs, partially offset by higher product revenues.
• As of June 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 second quarter of 2023, Gilead generated $2.3 billion in operating cash flow.
• During the second quarter of 2023, Gilead paid dividends of $944 million and repurchased $150 million of common stock.

Product Sales Performance

Total second quarter 2023 product sales increased 7% to $6.6 billion compared to the same period in 2022. Total product sales, excluding Veklury, increased 11% to $6.3 billion in the second quarter of 2023 compared to the same period in 2022, primarily due to increased sales related to HIV, Cell Therapy and Trodelvy® (sacituzumab govitecan-hziy).

HIV product sales increased 9% to $4.6 billion in the second quarter of 2023 compared to the same period in 2022, primarily driven by favorable pricing dynamics and higher demand, partially offset by lower channel inventory.

• Biktarvy® (bictegravir 50mg/emtricitabine 200mg (“FTC”)/tenofovir alafenamide 25mg (“TAF”)) sales increased 17% year-over-year in the second quarter of 2023, primarily driven by higher demand and favorable pricing dynamics, partially offset by lower channel inventory.
• Descovy® (FTC 200mg/TAF 25mg) sales increased 12% year-over-year in the second quarter of 2023, primarily driven by favorable pricing dynamics and higher demand, partially offset by lower channel inventory.

The Liver Disease portfolio sales, which includes chronic hepatitis C virus (“HCV”), chronic hepatitis B virus (“HBV”), and chronic hepatitis delta virus (“HDV”), increased 4% to $711 million in the second quarter of 2023 compared to the same period in 2022. The increase was primarily driven by higher demand, partially offset by unfavorable pricing dynamics.

Cell Therapy product sales increased 27% to $469 million in the second quarter of 2023 compared to the same period in 2022.

• Yescarta® (axicabtagene ciloleucel) sales increased 29% year-over-year to $380 million in the second 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”).
• Tecartus® (brexucabtagene autoleucel) sales increased 21% year-over-year to $88 million in the second quarter of 2023, primarily driven by increased demand in R/R adult acute lymphoblastic leukemia (“ALL”) and R/R mantle cell lymphoma (“MCL”).

Trodelvy sales increased by 63% to $260 million in the second quarter of 2023 compared to the same period in 2022, primarily driven by growing adoption in pre-treated HR+/HER2- metastatic breast cancer (“mBC”) in the United States.

Veklury sales decreased by 43% to $256 million for the second 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.

Second Quarter 2023 Product Gross Margin, Operating Expenses and Effective Tax Rate

• Product gross margin was 78.0% for the second quarter of 2023 compared to 76.5% for the same period in 2022. Non-GAAP product gross margin was 86.9% for the second quarter of 2023 compared to 85.6% in the same period in 2022.
• Research and development (“R&D”) expenses and non-GAAP R&D expenses for the second quarter of 2023 were $1.4 billion compared to $1.1 billion in the same period in 2022. The increases in GAAP and non-GAAP R&D expenses were primarily driven by higher clinical activities.
• Acquired in-process R&D (“IPR&D”) expenses for the second quarter of 2023 were $236 million, primarily driven by the acquisition of XinThera, Inc. (“XinThera”) and the expanded collaboration with Arcus Biosciences, Inc. (“Arcus”).
• Selling, general and administrative (“SG&A”) expenses for the second quarter of 2023 were $1.8 billion compared to $1.4 billion in the same period in 2022. Non-GAAP SG&A expenses for the second quarter of 2023 were $1.8 billion compared to $1.3 billion in the same period in 2022. The increases in GAAP and non-GAAP SG&A expenses were primarily driven by the litigation accrual referenced earlier, as well as increased commercial activities in Oncology and HIV, partially offset by lower corporate expenses.
• The effective tax rate (“ETR”) for the second quarter of 2023 was 34.6% compared to 24.5% for the same period in 2022, primarily driven by a remeasurement of certain deferred tax liabilities. Non-GAAP ETR for the second quarter of 2023 was 21.0% compared to 19.3% for the same period in 2022.

Guidance and Outlook

For the full-year, Gilead expects:

• Total product sales between $26.3 billion and $26.7 billion, compared to $26.0 billion and $26.5 billion previously.
• Total product sales, excluding Veklury, between $24.6 billion and $25.0 billion, compared to $24.0 billion and $24.5 billion previously.

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.
