Gilead Sciences : View First Quarter 2022 Earnings Release

GILEAD SCIENCES ANNOUNCES FIRST QUARTER 2022 FINANCIAL RESULTS

Biktarvy Sales Increased 18% Year-Over-Year to $2.2 billion

Oncology Sales Increased 60% Year-Over-Year to $420 million

Foster City, CA, April 28, 2022 - Gilead Sciences, Inc. (Nasdaq: GILD) announced today its results of operations for the first quarter of 2022.

"Gilead's performance in the first quarter reflects the strength and diversity of our business with both our HIV and oncology therapies contributing to year-over-year growth," said Daniel O'Day, Chairman and Chief Executive Officer, Gilead Sciences. "Biktarvy delivered strong 18% year-over-year revenue growth, and oncology sales increased by 60% year-over-year, driven by increased demand for Trodelvy and our cell therapy products. As we continue to advance our broad oncology portfolio, we look forward to providing more new options for people living with cancer."

First Quarter 2022 Financial Results

• • First quarter 2022 revenue increased 3% to $6.6 billion compared to the same period in 2021, primarily due to increased demand for Biktarvy® (bictegravir 50mg/emtricitabine 200mg ("FTC")/ tenofovir alafenamide 25mg ("TAF")) and Veklury® (remdesivir 100mg for injection), partially offset by the impact of the loss of exclusivity for Truvada® (FTC/tenofovir disoproxil fumarate 300mg ("TDF")) in the United States and unfavorable pricing dynamics for hepatitis C virus ("HCV") products.

• • Diluted Earnings Per Share ("EPS") decreased to $0.02 for the first quarter of 2022 compared to $1.37 for the same period in 2021. The decrease was primarily the result of a $2.7 billion in-process research and development ("IPR&D") impairment related to assets acquired by Gilead from Immunomedics in 2020.

• • Non-GAAP diluted EPS increased 4% to $2.12 for the first quarter of 2022 compared to $2.04(1) for the same period in 2021, primarily reflecting higher product sales.

• • As of March 31, 2022, Gilead had $6.8 billion of cash, cash equivalents and marketable debt securities compared to $7.8 billion as of December 31, 2021.

• • During the first quarter of 2022, Gilead generated $1.8 billion in operating cash flow, which includes the cash outflow related to the $1.25 billion legal settlement.

• • During the first quarter of 2022, Gilead made a $725 million collaboration opt-in payment to Arcus Biosciences, Inc., repaid $500 million of debt, paid dividends of $945 million and repurchased $352 million of common stock.

Product Sales Performance

First quarter 2022 product sales increased 3% to $6.5 billion compared to the same period in 2021. Total product sales, excluding Veklury, increased 2% to $5.0 billion in the first quarter of 2022 compared to the same period in 2021, primarily reflecting higher demand for Biktarvy, our cell therapy products and Trodelvy® (sacituzumab govitecan-hziy), partially offset by unfavorable pricing dynamics in HCV.

(1)

Non-GAAP diluted EPS has been recast due to an update to our non-GAAP policy in the first quarter 2022, resulting in a $0.04 reduction of previously-reported non-GAAP diluted EPS for the first quarter of 2021. Refer to Non-GAAP Financial Information section below for further information.

HIV product sales increased 2% to $3.7 billion in the first quarter of 2022 compared to the same period in 2021, primarily reflecting higher demand for Biktarvy and favorable pricing dynamics partially offset, as expected, by the loss of exclusivity of Truvada in the United States.

• • Biktarvy sales increased 18% year-over-year in the first quarter of 2022, primarily due to higher demand.

• • Descovy® (FTC 200mg/TAF 25mg) sales increased 4% year-over-year in the first quarter of 2022, primarily driven by increased demand and favorable pricing, partially offset by unfavorable channel inventory dynamics.

• • Truvada sales decreased 72% year-over-year in the first quarter 2022, as expected, primarily due to the loss of exclusivity in the United States in October 2020.

HCV product sales decreased 22% to $399 million in the first quarter of 2022 compared to the same period in 2021, primarily driven by lower net price and fewer patient starts.

Hepatitis B virus ("HBV") and hepatitis delta virus ("HDV") product sales increased 7% to $235 million in the first quarter of 2022 compared to the same period in 2021. Vemlidy® (TAF 25mg) sales increased 10% in the first quarter of 2022 compared to the same period in 2021, primarily driven by higher demand in geographies outside the United States. Hepcludex® (bulevirtide) contributed $11 million in the first quarter of 2022, as launch activities continued across Europe.

Cell therapy product sales increased 43% to $274 million in the first quarter of 2022 compared to the same period in 2021.

• • Yescarta® (axicabtagene ciloleucel) sales increased to $211 million in the first quarter of 2022, primarily driven by demand for relapsed or refractory large B-cell lymphoma ("LBCL") in the United States and Europe and follicular lymphoma in the United States.

• • Tecartus® (brexucabtagene autoleucel) sales were $63 million in the first quarter of 2022, primarily driven by growing adoption in Europe for mantle cell lymphoma and for adult patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia in the United States.

Trodelvy sales increased 103% to $146 million in the first quarter of 2022 compared to the same period in 2021, primarily reflecting uptake in the second line setting for the treatment of metastatic triple-negative breast cancer in the United States and Europe as well as metastatic urothelial cancer in the United States.

Veklury sales increased by 5% to $1.5 billion for the first quarter of 2022 compared to the same period in 2021. Veklury revenue generally reflects COVID-19 related rates of infections, hospitalizations and vaccinations, as well as the availability, uptake and effectiveness of alternative treatments for COVID-19.

First Quarter 2022 Product Gross Margin, Operating Expenses and Effective Tax Rate

• • Product gross margin was 78.2% for the first quarter of 2022 compared to 78.5% for the same period in 2021, primarily driven by a change in product mix and restructuring costs for the closing of a New Jersey manufacturing site in 2022, partially offset by lower inventory reserve adjustments. Non-GAAP product gross margin was 87.4% for the first quarter of 2022 compared to 86.5% in the same period in 2021, primarily driven by lower inventory reserve adjustments.

• • Research and development ("R&D") expenses for the first quarter of 2022 were $1.2 billion compared to $1.1 billion in the same period in 2021. Non-GAAP R&D expenses for the first quarter of 2022 were $1.2 billion compared to $1.0 billion in the same period in 2021. The increase in R&D and non-GAAP R&D expenses primarily reflect increased clinical activities for Trodelvy.

• • Selling, general and administrative ("SG&A") expenses were $1.1 billion for the first quarter of 2022 and for the same period in 2021. Non-GAAP SG&A expenses for the first quarter of 2022 were $1.1 billion compared to $1.0 billion in the same period in 2021.

• • The effective tax rate ("ETR") for the first quarter of 2022 was 107.9% compared to 23.9% for the same period in 2021, primarily driven by the $2.7 billion IPR&D impairment. Non-GAAP ETR for both the first quarter 2022 and the same period last year was 18.4%.

Guidance and Outlook

For the full-year, we have updated our EPS guidance to primarily reflect the $2.7 billion IPR&D impairment. We now expect EPS between $3.00 and $3.50, compared to $4.70 and $5.20 previously. There is no change to other guidance shared on February 1, 2022:

• • Total product sales between $23.8 billion and $24.3 billion.

• • Total product sales, excluding Veklury, between $21.8 billion and $22.3 billion.

• • Total Veklury sales of approximately $2.0 billion.

• • Non-GAAP earnings per share between $6.20 and $6.70.

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

Viral Diseases

• • Received a Complete Response Letter from FDA related to vial compatibility issues for the New Drug Application of investigational lenacapavir for the treatment of HIV-1 infection in heavily treatment-experienced ("HTE") people with multi-drug resistant HIV-1 infection.

• • Presented one-year data from studies of investigational lenacapavir at the 29th Conference on Retroviruses and Opportunistic Infections ("CROI") with results from each of the Phase 2/3 CAPELLA trial in HTE people living with multi-drug resistant HIV and Phase 2 CALIBRATE trial in treatment-naive people living with HIV demonstrating high rates of virologic suppression at one-year.

• • Presented five-year results from two Phase 3 studies of Biktarvy at CROI which reinforced Biktarvy's sustained efficacy and durable viral suppression with zero cases of treatment failure due to emergent resistance observed.

• • Announced data demonstrating in vitro activity of Veklury against ten SARS-CoV-2 variants, including Omicron. Additionally, interim results from the Phase 2/3 CARAVAN trial of Veklury in pediatric patients aged 28 days to less than 18 years hospitalized with COVID-19 were presented at CROI.

Oncology

• • Announced results from the Phase 3 TROPiCS-02 study of Trodelvy in patients with HR+/HER2-metastatic breast cancer who had been heavily pre-treated. The study met its primary endpoint, demonstrating a statistically significant improvement in progression-free survival compared to physician's choice of chemotherapy. Additionally, at the first interim analysis, a trend in improvement for overall survival ("OS") was observed, a key secondary endpoint. No new safety concerns were noted. The company will discuss the study data with regulators and the study will continue to follow patients for OS and detailed results will be presented at an upcoming medical conference. 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.

• • Received FDA approval for Yescarta for the treatment of adult patients with LBCL that is refractory to first-line chemoimmunotherapy or that relapse within 12 months of first-line chemoimmunotherapy. Additionally, the National Comprehensive Cancer Network updated its Clinical Practice Guidelines for B-cell Lymphomas to include Yescarta as a Category 1 recommendation for "Relapsed disease <12 mo or Primary refractory disease" under diffuse large B-cell lymphoma.

• • Announced that FDA has lifted the partial clinical hold on studies evaluating investigational magrolimab in combination with azacitidine for the treatment of myelodyspastic syndrome and acute myeloid leukemia.

Corporate

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

• • Announced $24 million in grants to support 116 organizations in 41 countries as part of Gilead's Zeroing InTM: Ending the HIV Epidemic program. Grantee organizations will focus on advancing comprehensive HIV innovation programs, digital health innovations, and/or community outreach and education.

• • Received FDA approval for commercial production at Kite's new CAR T-cell therapy manufacturing facility in Frederick, Maryland.

• • Purchased approximately 27 acres of additional land in Oceanside, California to potentially support further manufacturing operations.

Certain amounts and percentages in this press release may not sum or recalculate due to rounding.

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 acquired IPR&D expenses from its non-GAAP financial measures. Acquired IPR&D expenses reflect the initial costs of externally-developed IPR&D projects, acquired directly in a transaction other than a business combination, that do not have an alternative future use, including upfront and other payments related to various collaborations and the initial costs of rights to IPR&D projects. Prior period non-GAAP financial measures are revised to conform to the new presentation.

Conference Call

At 1:30 p.m. Pacific Time today, Gilead will host a conference call to discuss Gilead's results. A live webcast will be available onhttp://investors.gilead.comand will be archived on www.gilead.com for one year.

These risks and uncertainties include those relating to: the impact of the COVID-19 pandemic on Gilead's business, financial condition and results of operations; the development, manufacturing and distribution of Veklury as a treatment for COVID-19, including the uncertainty of the amount and timing of future Veklury sales and Gilead's ability to effectively manage the global supply and distribution of Veklury; Gilead's ability to achieve its anticipated full year 2022 financial results, including as a result of potential adverse revenue impacts from COVID-19 and potential revenues from Veklury; 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; Gilead's ability to initiate, progress or complete clinical trials within currently anticipated timeframes or at all, the risk that FDA may not remove clinical holds currently in place on any clinical trials, the possibility of unfavorable results from ongoing and additional clinical trials, including those involving Biktarvy, Trodelvy, Veklury, Yescarta, lenacapavir and magrolimab, 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 provide the requested documentation and address the comments in a Complete Response Letter to the satisfaction of the FDA; Gilead's ability to receive regulatory approvals in a timely manner or at all, including FDA approval of Trodelvy for treatment of HR+/HER2-metastatic breast cancer and other indications and lenacapavir for treatment of HIV-1 infection in heavily treatment-experienced people with multi-drug resistant infection, and the risk that any such approvals 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, including the risk that Kite may be unable to increase its manufacturing capacity, timely manufacture and deliver its products or produce an amount of supply sufficient to satisfy demand for such 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. In addition, Gilead makes estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures.
