Operating Expenses

Three Months Ended							Twelve Months Ended
December 31,							December 31,
(In millions)	2017			2016			2017		2016
Research and development (R&D) expenses	$	1,150	$	1,208	$	3,734	$	5,098
Non-GAAP R&D expenses^*	$	845	$	959	$	3,291	$	3,749
Selling, general and administrative (SG&A) expenses	$	1,252	$	992	$	3,878	$	3,398
Non-GAAP SG&A expenses^*	$	923	$	938	$	3,363	$	3,194

*	Non-GAAP R&D and SG&A expenses exclude acquisition-related, up-front collaboration, stock-based compensation and other expenses. A reconciliation between GAAP and non-GAAP financial information is provided in the tables on pages 8, 9 and 10.

During the fourth quarter of 2017, compared to the same period in 2016:

R&D expenses decreased primarily due to the 2016 impacts of ongoing milestone payments and an impairment charge related to in-process R&D (IPR&D), partially offset by Gilead’s purchase of Cell Design Labs, Inc. (Cell Design Labs) in 2017.
Non-GAAP R&D expenses^* decreased primarily due to the 2016 impact of ongoing milestone payments.
SG&A expenses increased primarily due to acquisition-related costs associated with Gilead’s acquisition of Kite Pharma, Inc. (Kite).

For 2017 compared to 2016:

R&D expenses decreased primarily due to the 2016 impacts of impairment charges related to IPR&D, ongoing milestone payments, up-front collaboration expenses related to Gilead’s license and collaboration agreement with Galapagos NV and Gilead’s purchase of Nimbus Apollo, Inc., partially offset by Gilead’s purchase of Cell Design Labs in 2017.
Non-GAAP R&D expenses^* decreased primarily due to the 2016 impact of ongoing milestone payments.
SG&A expenses increased primarily due to acquisition-related costs associated with Gilead’s acquisition of Kite.
Non-GAAP SG&A expenses^* increased primarily due to higher branded prescription drug fee expense.

Provision for Income Taxes and Tax Reform

Provision for income taxes was $6.0 billion for the fourth quarter of 2017 compared to $821 million for the same period in 2016 and $8.9 billion for the full year 2017 compared to $3.6 billion in 2016. The increases were primarily due to an estimated charge of $5.5 billion from Tax Reform, which was enacted on December 22, 2017 and lowers U.S. corporate income tax rates as of January 1, 2018, implements a territorial tax system and imposes a repatriation tax on deemed repatriated earnings of foreign subsidiaries. This estimate is provisional and based on our initial analysis and current interpretation. Given the complexity of the legislation, anticipated guidance from the U.S. Treasury, and the potential for additional guidance from the Securities and Exchange Commission (“SEC”) or the Financial Accounting Standards Board, this estimate may be adjusted during 2018.

Non-GAAP provision for income taxes excludes the estimated charge of $5.5 billion from Tax Reform. A reconciliation between GAAP and non-GAAP financial information is provided in the tables on pages 8, 9 and 10.

Cash, Cash Equivalents and Marketable Securities

As of December 31, 2017, Gilead had $36.7 billion of cash, cash equivalents and marketable securities compared to $32.4 billion as of December 31, 2016. During 2017, Gilead generated $11.9 billion in operating cash flow and in connection with the acquisition of Kite, Gilead issued $3.0 billion aggregate principal amount of senior unsecured notes and $6.0 billion aggregate principal amount of term loan facilities, of which $1.5 billion was repaid in December 2017. Additionally, Gilead paid cash dividends of $2.7 billion and utilized $954 million on stock repurchases.

Product & Pipeline Updates announced by Gilead during the Fourth Quarter of 2017 include:

HIV and Liver Diseases Programs

Presented data at The Liver Meeting^®2017 which included the announcement of:
- Results from a Phase 2, randomized, placebo-controlled trial evaluating two doses of GS-0976, an oral, investigational inhibitor of Acetyl-CoA carboxylase, in patients with nonalcoholic steatohepatitis (NASH). The data demonstrate that the higher dose of GS-0976 (20 mg taken orally once daily) when administered for 12 weeks was associated with statistically significant reductions in hepatic steatosis (buildup of fat in the liver) and a noninvasive marker of fibrosis compared to placebo.
- Results from an open-label Phase 2 study evaluating once-daily Harvoni for 12 weeks among HCV genotype 1 patients with severe renal impairment (creatinine clearance ≤ 30 mL/min). 100 percent of patients achieved a sustained virologic response 12 weeks after completing therapy (SVR12), including patients with compensated cirrhosis and those who had failed prior treatment.
- Results from an open-label Phase 2 study evaluating once-daily Epclusa for 12 weeks among 79 liver transplant patients with genotype 1-4 chronic HCV infection. Treatment with Epclusa resulted in an overall SVR12 rate of 96 percent, including patients with cirrhosis and prior treatment failure, and was well tolerated.
- Updated results from two Phase 3 studies demonstrating improved long-term bone and renal safety in HBV-infected patients 48-weeks after switching from Viread^®(tenofovir disoproxil fumarate 300mg) to Vemlidy^® (tenofovir alafenamide 25mg).
Announced detailed 48-week results from a Phase 3 study evaluating the efficacy and safety of switching virologically suppressed HIV-1 infected adult patients from a multi-tablet regimen containing a boosted protease inhibitor (bPI) to a fixed-dose combination of bictegravir (50 mg) (BIC), a novel investigational integrase strand transfer inhibitor, and emtricitabine/tenofovir alafenamide (200/25 mg) (FTC/TAF), a dual-NRTI backbone. In the ongoing study, BIC/FTC/TAF was found to be statistically non-inferior to regimens containing bPIs and demonstrated no treatment-emergent resistance at 48 weeks. The data were presented at IDWeek 2017.
Announced a new licensing agreement with the Medicines Patent Pool (MPP), a United Nations-backed public health organization, to expand access to BIC upon regulatory approval in the United States. Through this agreement, MPP can sub-license rights to BIC to generic drug companies in India, China and South Africa to manufacture therapies containing BIC for distribution in 116 low- and middle-income countries.

Oncology and Cell Therapy Programs

Announced updated results from the ongoing Phase 1/2 ZUMA-3 study of KTE-C19, a CD19 chimeric antigen receptor T (CAR T) cell therapy, which is investigational, for the treatment of adult patients with relapsed or refractory acute lymphoblastic leukemia (ALL). With a minimum of eight weeks of follow-up, 71 percent of ALL patients (n=17/24) who received a single infusion of KTE-C19 achieved complete tumor remission (complete remission (CR) or CR with incomplete hematological recovery). The ZUMA-3 study results were presented in an oral session at the Annual Meeting of the American Society of Hematology.
Announced long-term follow-up data from the ZUMA-1 study of Yescarta™ (axicabtagene ciloleucel) in patients with refractory large B-cell lymphoma. With a minimum follow-up of one year after a single infusion of Yescarta (median follow-up of 15.4 months), 42 percent of patients continued to respond to therapy, including 40 percent with a complete remission. Detailed results from this updated analysis were simultaneously presented at the Annual Meeting of the American Society of Hematology, and published in The New England Journal of Medicine.
Announced that U.S. Food and Drug Administration has granted regular approval to Yescarta, the first CAR T cell therapy for the treatment of adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high-grade B-cell lymphoma, and DLBCL arising from follicular lymphoma (transformed follicular lymphoma).

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 2018 financial results; Gilead’s ability to sustain growth in revenues for its antiviral and other programs; the risk that private and public payers may be reluctant to provide, or continue to provide, coverage or reimbursement for new products, including Vosevi, Yescarta, Epclusa, Harvoni, Genvoya, Odefsey, Descovy and Vemlidy; austerity measures in European countries that may increase the amount of discount required on Gilead’s products; an increase in discounts, chargebacks and rebates due to ongoing contracts and future negotiations with commercial and government payers; a larger than anticipated shift in payer mix to more highly discounted payer segments and geographic regions and decreases in treatment duration; availability of funding for state AIDS Drug Assistance Programs (ADAPs); continued fluctuations in ADAP purchases driven by federal and state grant cycles which may not mirror patient demand and may cause fluctuations in Gilead’s earnings; market share and price erosion caused by the introduction of generic versions of Viread and Truvada outside the United States, an uncertain global macroeconomic environment; and potential amendments to the Affordable Care Act or other government action that could have the effect of lowering prices or reducing the number of insured patients; the possibility of unfavorable results from clinical trials involving investigational compounds; Gilead’s ability to initiate clinical trials in its currently anticipated timeframes; the levels of inventory held by wholesalers and retailers which may cause fluctuations in Gilead’s earnings; 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 BIC/FTC/TAF; Gilead’s ability to successfully commercialize its products, including Vosevi, Yescarta, Epclusa, Harvoni, Genvoya, Odefsey, Descovy and Vemlidy; 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; Gilead’s ability to successfully develop its hematology/oncology and inflammation/respiratory programs; safety and efficacy data from clinical studies may not warrant further development of Gilead’s product candidates, including GS-0976 and KTE-C19; Gilead’s ability to pay dividends or complete its share repurchase program due to changes in its stock price, corporate or other market conditions; fluctuations in the foreign exchange rate of the U.S. dollar that may cause an unfavorable foreign currency exchange impact on Gilead’s future revenues and pre-tax earnings; and other risks identified from time to time in Gilead’s reports filed with 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. Actual results may differ significantly from these estimates. You are urged to consider statements that include the words may, will, would, could, should, might, believes, estimates, projects, potential, expects, plans, anticipates, intends, continues, forecast, designed, goal, or the negative of those words or other comparable words to be uncertain and forward-looking. Gilead directs readers to its press releases, Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 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.
