THOUSAND OAKS, Calif., Feb. 3, 2026 /PRNewswire/ -- Amgen (NASDAQ: AMGN) today announced financial results for the fourth quarter and full year of 2025 versus the comparable periods in 2024.

"Amgen delivered strong performance in 2025, with double-digit growth in revenues and earnings per share. We enter 2026 with momentum across a broad portfolio of medicines and a clear path towards advancing innovative therapies to deliver sustained long-term growth," said Robert A. Bradway, chairman and chief executive officer.

Key results include:

• For the fourth quarter, total revenues increased 9% to $9.9 billion in comparison to the fourth quarter of 2024.
  • Product sales grew 7%, driven by 10% volume growth, partially offset by 4% lower net selling price.
• For the full year, total revenues increased 10% to $36.8 billion in comparison to the full year of 2024.
  • Product sales grew 10%, driven by 13% volume growth, partially offset by 3% lower net selling price.
  • Eighteen products achieved record sales for the full year.
  • Fourteen products exceeded one billion dollars in annual sales.
  • Thirteen products delivered at least double-digit sales growth for the full year.
• GAAP earnings per share (EPS) increased 111% from $1.16 to $2.45 for the fourth quarter, driven by higher revenues and lower net unrealized losses on equity investments, partially offset by higher operating expenses. For the full year, GAAP EPS increased 88% from $7.56 to $14.23, driven by higher revenues and net unrealized gains on our BeOne Medicines Ltd. (BeOne) equity investment, partially offset by higher operating expenses, including Otezla^® (apremilast) intangible asset impairment charges of $1.2 billion recorded in 2025, following the selection of Otezla^® for Medicare price setting, as part of the Inflation Reduction Act (IRA).
  • For the fourth quarter, GAAP operating income increased from $2.3 billion to $2.7 billion, and GAAP operating margin increased 2.5 percentage points to 29.0%. For the full year, GAAP operating income increased from $7.3 billion to $9.1 billion, and GAAP operating margin increased 3.1 percentage points to 25.8%.
• Non-GAAP EPS remained relatively unchanged from $5.31 to $5.29 for the fourth quarter as higher operating expenses were partially offset by higher revenues. For the full year, non-GAAP EPS increased 10% from $19.84 to $21.84, driven by higher revenues, partially offset by higher operating expenses.
  • For the fourth quarter, non-GAAP operating income remained relatively unchanged at $4.0 billion, and non-GAAP operating margin decreased 3.5 percentage points to 42.8%. For the full year, non-GAAP operating income increased from $15.0 billion to $16.2 billion, and non-GAAP operating margin decreased 0.8 percentage points to 46.1%.
• The Company generated $8.1 billion of free cash flow for the full year of 2025 versus $10.4 billion for the full year of 2024, driven by timing of working capital, primarily collections and higher capital expenditures, partially offset by business performance and lower interest payments.

Operating Expense, Operating Margin and Tax Rate Analysis

On a GAAP basis:

• Total Operating Expenses increased 5% year-over-year for the fourth quarter and increased 6% for the full year. Cost of Sales as a percentage of product sales decreased 3.9 percentage points for the fourth quarter and decreased 5.9 percentage points for the full year, driven by lower amortization expense from acquisition-related assets, including Horizon-acquired inventory, and lower manufacturing costs, partially offset by higher profit share expense and changes in our sales mix. Research & Development (R&D) expenses increased 24% for the fourth quarter primarily driven by higher spend in the later-stage clinical programs, including MariTide, and in the research and early pipeline, including business development activities in the fourth quarter of 2025. R&D expenses increased 22% for the full year driven by higher spend in the later-stage clinical programs, including MariTide, and in the research and early pipeline, partially offset by lower spend in marketed product support. This increase includes the impact of business development activities in 2025. Selling, General & Administrative (SG&A) expenses increased 4% for the fourth quarter driven by higher commercial product-related expenses, partially offset by lower Horizon acquisition-related expenses and lower general and administrative expenses. SG&A expenses decreased 1% for the full year driven by lower Horizon acquisition-related expenses and lower amortization expense from acquisition-related assets, partially offset by higher general and administrative expenses, including technology-related spend. Other operating expenses for the full year included Otezla^® intangible asset impairment charges of $1.2 billion, following the selection of Otezla^® for Medicare price setting, as part of the Inflation Reduction Act (IRA).
• Operating Margin as a percentage of product sales increased 2.5 percentage points to 29.0% for the fourth quarter and increased 3.1 percentage points to 25.8% for the full year.
• Tax Rate decreased 7.8 percentage points for the fourth quarter and increased 2.8 percentage points for the full year. The fourth quarter tax rate decrease was due to the prior-year deferred tax adjustments associated with the U.S. tax on the earnings of our foreign subsidiaries, partially offset by the change in earnings mix, including lower amortization expense from the fair value step-up of inventory acquired from Horizon as compared to the prior year. The full year tax rate increase was due to the change in earnings mix, including the net unrealized gains on our equity investments compared to net unrealized losses on equity investments in the prior year, partially offset by the prior-year deferred tax adjustments associated with U.S. tax on the earnings of our foreign subsidiaries and the current year Otezla^® intangible asset impairment charges and related tax impacts.

On a non-GAAP basis:

• Total Operating Expenses increased 16% year-over-year for the fourth quarter and increased 12% for the full year. Cost of Sales as a percentage of product sales increased 1.5 percentage points for the fourth quarter and increased 0.4 percentage points for the full year, driven by higher profit share expense and changes in our sales mix, partially offset by lower manufacturing costs. R&D expenses increased 26% for the fourth quarter driven by higher spend in the later-stage clinical programs, including MariTide, and in the research and early pipeline, including business development activities in the fourth quarter of 2025. R&D expenses increased 22% for the full year driven by higher spend in the later-stage clinical programs, including MariTide, and in the research and early pipeline, partially offset by lower spend in marketed product support. This increase includes the impact of business development activities in 2025. SG&A expenses increased 6% for the fourth quarter driven by higher commercial product-related expenses, partially offset by lower general and administrative expenses. SG&A expenses increased 2% for the full year driven by higher general and administrative expenses, including technology-related spend.

• Tax Rate increased 1.6 percentage points for the fourth quarter and increased 1.4 percentage points for the full year. The fourth quarter tax rate increase was primarily due to prior year net favorable items as compared to the current year. The full year tax rate increase was due to the change in earnings mix and prior year net favorable items as compared to the current year.

Cash Flow and Balance Sheet

• The Company generated $1.0 billion of free cash flow in the fourth quarter of 2025 versus $4.4 billion in the fourth quarter of 2024, driven by timing of working capital, primarily collections, timing of tax payments and higher capital expenditures, partially offset by business performance. The Company generated $8.1 billion of free cash flow for the full year of 2025 versus $10.4 billion in 2024.

Non-GAAP Financial Measures
In this news release, management has presented its operating results for the fourth quarters and full years of 2025 and 2024, in accordance with U.S. Generally Accepted Accounting Principles (GAAP) and on a non-GAAP basis. In addition, management has presented its full year 2026 EPS and tax guidance in accordance with GAAP and on a non-GAAP basis. These non-GAAP financial measures are computed by excluding certain items related to acquisitions, divestitures, restructuring and certain other items from the related GAAP financial measures. Management has presented Free Cash Flow (FCF), which is a non-GAAP financial measure, for the fourth quarters and full years of 2025 and 2024. FCF is computed by subtracting capital expenditures from operating cash flow, each as determined in accordance with GAAP. Management has also presented Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) and debt leverage ratio for 2025, both of which are non-GAAP financial measures. EBITDA is computed by adding interest expense, provision for income taxes, and depreciation and amortization expense to GAAP net income. Debt leverage ratio is calculated as the ratio of GAAP total debt to EBITDA.

The Company believes that its presentation of non-GAAP financial measures provides useful supplementary information to and facilitates additional analysis by investors. The Company uses certain non-GAAP financial measures to enhance an investor's overall understanding of the financial performance and prospects for the future of the Company's normal and recurring business activities by facilitating comparisons of results of normal and recurring business operations among current, past and future periods. The Company believes that FCF provides a further measure of the Company's liquidity. The Company believes its debt leverage ratio provides a supplemental operating metric for the full year period as it compares the amount of cash generated by our operations for the year.

The Company uses the non-GAAP financial measures set forth in the news release in connection with its own budgeting and financial planning internally to evaluate the performance of the business, including to allocate resources and to evaluate results relative to incentive compensation targets. The non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

Forward-Looking Statements
This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeOne Medicines Ltd. or Kyowa Kirin Co., Ltd.), the performance of Otezla^® (apremilast), our acquisitions of ChemoCentryx, Inc., Dark Blue Therapeutics, Ltd. or Horizon Therapeutics plc (including the prospective performance and outlook of Horizon's business, performance and opportunities, and any potential strategic benefits, synergies or opportunities expected as a result of such acquisition), as well as estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes, effects of pandemics or other widespread health problems on our business, outcomes, progress, and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions, including those resulting from geopolitical relations and government actions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. An outbreak of disease or similar public health threat, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful, and may result in unanticipated costs, delays or failures to realize the benefits of the transactions. A breakdown, cyberattack or information security breach of our information technology systems could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Our business and operations may be negatively affected by the failure, or perceived failure, of achieving our sustainability objectives. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.
