Net income attributable to Gilead was $5.7 billion and diluted earnings per share attributable to Gilead was $4.50 in 2023, compared to $4.6 billion and $3.64 diluted earnings per share attributable to Gilead in 2022. The increase was primarily due to lower in-process research and development (“IPR&D”) impairment expenses, lower net unrealized losses on equity investments and higher interest income, partially offset by higher costs of goods sold and operating expenses, and lower revenues.

Current wording

Net income attributable to Gilead was $480 million and diluted earnings per share attributable to Gilead was $0.38 in 2024, compared to net income attributable to Gilead of $5.7 billion and $4.50 diluted earnings per share attributable to Gilead in 2023. The decrease was primarily due to:

Of the $16.4 billion in 2023, $14.3 billion or 33% of gross product sales was related to rebates and chargebacks, $2.2 billion or 5% was primarily related to patient co-pay assistance, cash discounts for prompt payment, distributor fees, and sales return provisions.

Product gross margin decreased to 75.9% in 2023, compared to 2022, primarily driven by higher intangible asset amortization expenses related to the pretreated HR+/HER2- metastatic breast cancer indication for Trodelvy following its approval in February 2023, restructuring expenses related to changes in our manufacturing strategy, which resulted in write-offs of certain manufacturing facilities, related inventories and other costs totaling $479 million, and product mix, partially offset by higher amortization of inventory step-up charges in 2022.

The following table summarizes our cash flow activities:

Current wording

Cash and cash equivalents were $10.0 billion as of December 31, 2024. The table below summarizes our cash flow activities, followed by our analysis of changes and trends:

Previous wording

Net cash used in financing activities was $5.1 billion in 2023, compared to $6.5 billion in 2022. In 2023, we utilized cash of $2.3 billion for debt repayments, $3.8 billion for dividend payments and $1.0 billion for common stock repurchases. These were partially offset by $2.0 billion in proceeds from the issuance of senior unsecured notes in September 2023, net of issuance costs. In 2022, we utilized cash of $1.5 billion for debt repayments, $3.7 billion for dividend payments, and $1.4 billion for common stock repurchases.

Current wording

Net cash used in financing activities in 2024 was primarily the result of $2.0 billion for debt repayments, $3.9 billion for dividend payments and $1.2 billion for common stock repurchases, partially offset by $3.5 billion in net proceeds from the issuance of senior unsecured notes in November 2024. In 2023, we utilized cash of $2.3 billion for debt repayments, $3.8 billion for dividend payments and $1.0 billion for common stock repurchases, partially offset by $2.0 billion in net proceeds from the issuance of senior unsecured notes in September 2023. The year-over-year changes were due mostly to higher cash provided by new debt issuances. Net cash used in financing activities may vary in any given year depending primarily on the timing of debt repayments and proceeds from debt offerings and the amount of common stock repurchases.

Previous wording

As of December 31, 2023, our material cash requirements consisted primarily of the repayment of outstanding borrowings, income tax payments, including the remaining obligations for the one-time repatriation transition tax from the Tax Cuts and Jobs Act, purchases of inventory, operating lease obligations, capital expenditures and milestone and other payments related to our collaborative agreements. See Notes 6. Acquisitions, 7. Collaborations and Other Arrangements, 11. Debt and Credit Facilities, 12. Leases, 13. Commitments and Contingencies and 16. Income Taxes of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for additional information.

There have been no changes to these commitments during the year that would have a material impact on the company’s ability to meet either short-term or long-term cash requirements.

See Note 1. Organization and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for information about our significant accounting policies and how estimates are involved in the preparation of our financial statements. We believe the following reflect the critical accounting estimates used in the preparation of our Consolidated Financial Statements.

Current wording

See Note 1. Summary of Business and Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for information about our significant accounting policies and how estimates are involved in the preparation of our financial statements. We believe the following reflect the critical accounting estimates used in the preparation of our Consolidated Financial Statements.

Previous wording

These estimates are subject to uncertainty due to the high rate of failure inherent in the discovery and development of new products; delays that can occur in development, approval and product launch processes; unanticipated decisions made by regulatory agencies; advent of competing products; unexpected changes in U.S. and global financial markets and other unanticipated events and circumstances. If future events result in adverse changes in the critical assumptions used in determining fair value, impairment charges on our intangible assets may be recorded and could be material to our financial statements. For example, in 2022, we recognized a $2.7 billion impairment charge related to our HR+/HER2- IPR&D intangible asset related to an expected delay in launch timing which caused a decrease in our market share assumptions based on the expected competitive environment.

Current wording

These estimates are subject to uncertainty due to the high rate of failure inherent in the discovery and development of new products; delays that can occur in development, approval and product launch processes; unanticipated decisions made by regulatory agencies; advent of competing products; unexpected changes in U.S. and global financial markets and other unanticipated events and circumstances. If future events result in adverse changes in the critical assumptions used in determining fair value, impairment charges on our intangible assets may be recorded and could be material to our financial statements. For example, in 2024, upon receiving data from our Phase 3 EVOKE-01 study of Trodelvy, which indicated the study did not meet its primary endpoint, and further discussions with regulators and external opinion leaders and completion of the evaluation of the trial data which led to the strategic decision to end the second-line indication program, we recognized in aggregate $4.2 billion in impairment charges related to our NSCLC IPR&D intangible asset, reflecting, amongst other changes, the removal of expected future cash flows associated with second-line plus patients from our valuation model.

Previous wording

Critical inputs to the accruals recorded and disclosures provided in relation to these matters include the probability of a certain outcome of the case, the determination as to whether an exposure is reasonably estimable and the amount of potential exposure. These inputs are subject to uncertainty due to changes in the legal facts and circumstances of the case, status of the proceedings, applicable law, the views of legal counsel and the views of any judges or jury involved in the case. Upon the final resolution of such matters, it is possible that there may be a loss in excess of the amount recorded, and such amounts could have a material adverse effect on our results of operations, cash flows or financial position. We periodically reassess these matters when additional information becomes available and adjust our estimates and assumptions when facts and circumstances indicate the need for any changes. For example, in the second quarter of 2023, we recorded an accrual of $525 million in Other current liabilities on our Consolidated Balance Sheets for settlements with certain plaintiffs in the HIV antitrust litigation, which we paid in the second half of 2023.
