                    Non-GAAP financial information excludes acquisition-related, up-front collaboration and licensing, stock-based compensation and other expenses, fair value adjustments of equity securities and discrete tax charges or benefits associated with changes in tax related laws and guidelines. A reconciliation between GAAP and non-GAAP financial information is provided in the tables on pages 9 through 12.

                    For the fourth quarter of 2019, compared to the same period in 2018, net income attributable to Gilead increased primarily due to the net favorable tax effects of intra-entity intangible asset transfers to different tax jurisdictions and an increase in net gains from equity securities. In addition, during the fourth quarter of 2019 and 2018, Gilead recorded pre-tax impairment charges of $800 million and $820 million, respectively, related to in-process research and development (IPR&D) intangible assets acquired in connection with the acquisition of Kite Pharma, Inc. (Kite) and pre-tax write-downs of $500 million and $410 million, respectively, for slow moving and excess raw material and work in process inventory.

                    In addition to the factors noted above, the full year 2019, compared to the same period in 2018, was impacted by pre-tax up-front collaboration and licensing expenses of $3.92 billion related to Gilead’s global research and development collaboration agreement with Galapagos NV (Galapagos) in 2019.

                    The following tables summarize significant items that impacted the comparability of net income attributable to Gilead and diluted earnings per share in the periods presented:

                    Product Sales

                    Total product sales for the fourth quarter of 2019 were $5.8 billion, compared to $5.7 billion for the same period in 2018. Product sales for the fourth quarter of 2019 were $4.5 billion in the United States, $840 million in Europe and $440 million in other locations. Product sales for the fourth quarter of 2018 were $4.5 billion in the United States, $813 million in Europe and $398 million in other locations.

                    Total product sales in 2019 were $22.1 billion, compared to $21.7 billion in 2018. For 2019, product sales were $16.6 billion in the United States, $3.6 billion in Europe and $2.0 billion in other locations. For 2018, product sales were $16.2 billion in the United States, $3.7 billion in Europe and $1.8 billion in other locations.

                    • HIV product sales were $4.6 billion for the fourth quarter of 2019 compared to $4.1 billion for the same period in 2018. For 2019, HIV product sales were $16.4 billion compared to $14.6 billion in 2018. The increases were primarily driven by higher sales volume as a result of the continued uptake of Biktarvy? (bictegravir 50 mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg).
                    • Chronic hepatitis C virus (HCV) product sales were $630 million for the fourth quarter of 2019 compared to $738 million for the same period in 2018. For 2019, HCV product sales were $2.9 billion compared to $3.7 billion in 2018. The declines were primarily due to lower average net selling price.
                    • Yescarta? (axicabtagene ciloleucel) generated $122 million in sales during the fourth quarter of 2019 compared to $81 million in 2018. For 2019, Yescarta sales were $456 million compared to $264 million in 2018. The increases were driven by a higher number of therapies provided to patients and the continued expansion in Europe.
                    • Other product sales, which include products from chronic hepatitis B virus (HBV), cardiovascular, oncology and other categories, inclusive of Vemlidy? (tenofovir alafenamide 25 mg), Viread? (tenofovir disoproxil fumarate 300 mg), Letairis? (ambrisentan 5 mg and 10 mg), Ranexa? (ranolazine 500 mg and 1000 mg), Zydelig? (idelalisib 150 mg), AmBisome? (amphotericin B liposome for injection 50 mg/vial) and Cayston? (aztreonam for inhalation solution 75 mg/vial), were $467 million for the fourth quarter of 2019 compared to $797 million for the same period in 2018. For 2019, other product sales were $2.3 billion compared to $3.1 billion in 2018. The decreases were expected and primarily due to declines in Ranexa and Letairis sales after generic entries in 2019.

                    For the fourth quarter of 2019, compared to the same period in 2018:

                    • Cost of goods sold and non-GAAP cost of goods sold increased primarily due to higher inventory write-downs, partially offset by lower royalty expenses. During the fourth quarter of 2019 and 2018, Gilead recorded write-downs of $500 million and $410 million, respectively, for slow moving and excess raw material and work in process inventory primarily due to lower long-term demand for Gilead’s HCV products.
                    • Product gross margin and non-GAAP product gross margin decreased primarily due to the factors noted above.

                    For the full year 2019, compared to the same period in 2018:

                    • Cost of goods sold and non-GAAP cost of goods sold decreased primarily due to lower royalty expenses, partially offset by higher inventory write-downs. Costs of goods sold also decreased due to lower amortization expense related to intangible assets associated with Ranexa.
                    • Product gross margin and non-GAAP product gross margin increased primarily due to changes in product mix and the factors noted above.

                    For the fourth quarter of 2019, compared to the same period in 2018:

                    • R&D expenses decreased primarily due to lower up-front collaboration and licensing expenses, partially offset by higher personnel costs to support Gilead’s cell therapy business and increased investment in Gilead’s research projects. Gilead recorded impairment charges of $800 million in 2019 for the IPR&D intangible assets acquired in connection with the acquisition of Kite primarily related to the treatment of indolent non-Hodgkin lymphoma and $820 million in 2018 related to the KITE-585 program (an anti-B cell maturation antigen being evaluated for the treatment of multiple myeloma).
                    • Non-GAAP R&D expenses increased primarily due to higher personnel costs to support Gilead’s cell therapy business and increased investment in Gilead’s research projects.
                    • SG&A expenses and non-GAAP SG&A expenses increased primarily due to higher promotional expenses in the United States and expenses associated with the expansion of Gilead’s business in Japan.

                    For the full year 2019, compared to the same period in 2018:

                    • R&D expenses increased primarily due to up-front collaboration and licensing expenses of $3.92 billion related to Gilead’s global research and development collaboration agreement with Galapagos, partially offset by lower stock-based compensation expense associated with Gilead’s acquisition of Kite. Furthermore, R&D expenses and non-GAAP R&D expenses increased primarily due to higher personnel costs to support Gilead’s cell therapy business.
                    • SG&A expenses increased primarily due to promotional expenses in the United States and expenses associated with the expansion of Gilead’s business in Japan and China, partially offset by lower stock-based compensation expense associated with Gilead’s acquisition of Kite.
                    • Non-GAAP SG&A increased primarily due to promotional expenses in the United States and expenses associated with the expansion of Gilead’s business in Japan and China.

                    Cash, Cash Equivalents and Marketable Debt Securities

                    As of December 31, 2019, Gilead had $25.8 billion of cash, cash equivalents and marketable debt securities compared to $31.5 billion as of December 31, 2018. During 2019, Gilead generated $9.1 billion in operating cash flow, paid $5.6 billion in connection with the global research and development collaboration agreement with Galapagos and equity investments in Galapagos, repaid $2.8 billion of principal amount of debt, paid cash dividends of $3.2 billion and utilized $1.7 billion on stock repurchases.

                    Full Year 2020 Guidance

                    Gilead provides its full year 2020 guidance below. Starting in 2020, Gilead will no longer regularly exclude stock-based compensation expense from its non-GAAP financial information. For comparability purposes, full year 2019 non-GAAP operating income and non-GAAP diluted earnings per share would have been $10.4 billion and $6.13, respectively, had stock-based compensation expense not been excluded.

                    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 measures may be defined and calculated differently by other companies in the same industry. A reconciliation between GAAP and non-GAAP financial information is provided in the tables on pages 9 through 12.

                    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: Gilead’s ability to achieve its anticipated full year 2020 financial results; Gilead’s ability to accelerate or sustain revenues for its antiviral and other programs; Gilead’s ability to realize the potential benefits of collaborations or licensing arrangements, including those with The Rockefeller University, Kyverna Therapeutics, Inc., Eisai Co., Ltd., Kiniksa Pharmaceuticals, Ltd. and Glympse Bio, Inc.; Gilead’s ability to initiate clinical trials in its currently anticipated timeframes; the risk that safety and efficacy data from clinical studies may not warrant further development of Gilead’s product candidates, including Yescarta in combination with mavrilimumab, 3BNC117, 10-1074, GS-6207 and product candidates evaluated for bridging fibrosis and compensated cirrhosis due to NASH; Gilead’s ability to submit new drug applications for new product candidates in the timelines currently anticipated; Gilead’s ability to receive regulatory approvals in a timely manner or at all, for new and current products, including FDA and MHLW approvals for filgotinib for the treatment of RA and FDA and European Commission approvals of KTE-X19 for the treatment of mantle cell lymphoma; Gilead’s ability to successfully commercialize its products, including expansion in China; the risk that private and public payers may be reluctant to provide, or continue to provide, coverage or reimbursement for new products; 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; other risks identified from time to time in Gilead’s reports filed with the U.S. Securities and Exchange Commission (the SEC). 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 and the year ended December 31, 2019 are not necessarily indicative of operating results for any future periods. Gilead directs readers to its press releases, Quarterly Report on Form 10-Q for the quarter ended September 30, 2019 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. All forward-looking statements are based on information currently available to Gilead and Gilead assumes no obligation to update or supplement any such forward-looking statements other than as required by law. Any forward-looking statements speak only as of the date hereof or as of the dates indicated in the statements.

                    Starting in 2020, Gilead will no longer regularly exclude stock-based compensation expense from its non-GAAP financial information. For comparability purposes, full year 2019 non-GAAP operating income and non-GAAP diluted earnings per share would have been $10.4 billion and $6.13, respectively, had stock-based compensation expense not been excluded

                    (2)

                    Excludes the impact of any potential future acquisition-related, up-front collaboration and licensing and other expenses, 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
