AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2025 FINANCIAL RESULTS

THOUSAND OAKS, Calif. (Feb. 3, 2026) - 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.

References in this release to “non-GAAP” measures, measures presented “on a non-GAAP basis,” “free cash flow” (computed by subtracting capital expenditures from operating cash flow), “EBITDA, or earnings before interest, taxes, depreciation and amortization” (computed by adding interest expense, provision for income taxes, and depreciation and amortization expense to GAAP net income) and “debt leverage ratio” (calculated as the ratio of GAAP total debt to EBITDA) refer to non-GAAP financial measures. Adjustments to the most directly comparable GAAP financial measures and other items are presented on the attached reconciliations. Refer to Non-GAAP Financial Measures below for further discussion.

Product Sales Performance

General Medicine

•Repatha® (evolocumab) sales increased 44% year-over-year to $870 million in the fourth quarter, driven by 31% volume growth, 8% higher net selling price, and higher inventory levels. Sales increased 36% for the full year, driven by volume growth. For 2026, we expect net selling price to decline by roughly mid single-digits.

•EVENITY® (romosozumab-aqqg) sales increased 39% year-over-year to $599 million in the fourth quarter and 34% for the full year, primarily driven by volume growth.

•Prolia® (denosumab) sales decreased 10% year-over-year to $1.1 billion in the fourth quarter, driven by 8% lower net selling price and decreased volume. Sales increased 1% for the full year, primarily driven by 2% volume growth and 2% favorable changes to estimated sales deductions, partially offset by lower net selling price. For 2026, we expect accelerated sales erosion driven by increased competition, as multiple biosimilars have launched globally.

Rare Disease

•TEPEZZA® (teprotumumab-trbw) sales decreased 1% year-over-year to $457 million in the fourth quarter, primarily driven by 13% lower inventory levels and unfavorable changes to estimated sales deductions, partially offset by 11% volume growth and higher net selling price. Sales increased 3% for the full year, primarily driven by higher net selling price.

•KRYSTEXXA® (pegloticase) sales increased 26% year-over-year to $435 million in the fourth quarter, driven by higher inventory levels, higher net selling price, and volume growth. Sales increased 13% for the full year, driven by volume growth and higher net selling price.

•UPLIZNA® (inebilizumab-cdon) sales increased 131% year-over-year to $233 million in the fourth quarter and 73% for the full year, primarily driven by volume growth.

•TAVNEOS® (avacopan) sales increased 88% year-over-year to $152 million in the fourth quarter, primarily driven by 69% volume growth and 18% higher inventory levels. Sales increased 62% for the full year, driven by volume growth, partially offset by lower net selling price.

•Ultra-Rare products generated $157 million of sales in the fourth quarter. Sales decreased 27% year-over-year for the fourth quarter and 5% for the full year, primarily driven by generic competition for RAVICTI. For 2026, we expect continued RAVICTI sales erosion driven by generic competition.

Inflammation

•TEZSPIRE® (tezepelumab-ekko) sales increased 60% year-over-year to $474 million in the fourth quarter, primarily driven by 51% volume growth, and to a lesser degree, higher inventory levels and favorable changes to estimated sales deductions. Sales increased 52% for the full year, driven by volume growth.

•Otezla® (apremilast) sales were flat year-over-year at $625 million in the fourth quarter. Sales increased 7% for the full year, primarily driven by 3% volume growth and 2% favorable changes to estimated sales deductions.

•Enbrel® (etanercept) sales decreased 48% year-over-year to $532 million in the fourth quarter, primarily driven by 35% lower net selling price resulting from the impact of the U.S. Medicare Part D redesign and increased 340B Program mix, and 17% unfavorable changes to estimated sales deductions. Sales decreased 33% for the full year, primarily driven by 36% lower net selling price resulting from increased 340B Program mix, the impact of the U.S. Medicare Part D redesign and higher commercial discounts, partially offset by 4% higher volume.

We expect Enbrel and Otezla, and to a lesser extent KRYSTEXXA, TEZSPIRE and Repatha, to follow the historical pattern of lower sales in the first quarter relative to subsequent quarters, in part due to the impact of benefit plan changes, insurance reverification and increased co-pay expenses as U.S. patients work through deductibles.

•AMJEVITA® (adalimumab-atto)/AMGEVITA™ (adalimumab) sales decreased 41% year-over-year to $174 million in the fourth quarter, primarily driven by lower volume. Sales decreased 22% for the full year, driven by lower volume and lower net selling price.

•PAVBLU® (aflibercept-ayyh) generated $258 million of sales in the fourth quarter and $700 million for the full year. Sales increased 21% quarter-over-quarter, primarily driven by volume growth.

•WEZLANA® (ustekinumab-auub)/WEZENLA™ (ustekinumab) generated $44 million of sales in the fourth quarter and $273 million for the full year.

•XGEVA® (denosumab) sales decreased 20% year-over-year to $447 million in the fourth quarter and 6% for the full year, primarily driven by lower volume. For 2026, we expect accelerated sales erosion driven by increased competition, as multiple biosimilars have launched globally.

•Nplate® (romiplostim) sales increased 14% year-over-year to $385 million in the fourth quarter, primarily driven by 9% volume growth and 4% higher inventory levels.

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.

Page 8

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.

•Operating Margin as a percentage of product sales decreased 3.5 percentage points for the fourth quarter to 42.8% and decreased 0.8 percentage points to 46.1% for the full year.

•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.

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

AMGEN REPORTS FOURTH QUARTER AND FULL YEAR 2025 FINANCIAL RESULTS

Page 18

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.

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.

GAAP to Non-GAAP Reconciliations

(In millions, except per-share data)

(Unaudited)

The following table presents the computations for GAAP and non-GAAP diluted earnings per share:


	Three months ended December 31, 2025				Three months ended December 31, 2024
	GAAP		Non-GAAP		GAAP		Non-GAAP
Net income	$	1,333	$	2,875	$	627	$	2,879




Weighted-average shares for diluted EPS	543		543		542		542

Diluted EPS	$	2.45	$	5.29	$	1.16	$	5.31

	Twelve months ended December 31, 2025				Twelve months ended December 31, 2024
	GAAP		Non-GAAP		GAAP		Non-GAAP
Net income	$	7,711	$	11,837	$	4,090	$	10,734

Weighted-average shares for diluted EPS	542		542		541		541

Diluted EPS	$	14.23	$	21.84	$	7.56	$	19.84


(a)						The adjustments related primarily to noncash amortization of intangible assets and fair value step-up of inventory acquired from business combinations.

(b)						For the three months ended December 31, 2025, the adjustment related primarily to noncash amortization of intangible assets acquired from business combinations. For the three months ended December 31, 2024, and for the twelve months ended December 31, 2025 and 2024, the adjustments related primarily to acquisition-related expenses related to our Horizon acquisition.

(c)						For the three months ended December 31, 2025, the adjustment related primarily to business development transaction costs. For the three months ended December 31, 2024, and for twelve months ended December 31, 2025 and 2024, the adjustments related primarily to acquisition-related costs related to our Horizon acquisition.

(d)						For the twelve months ended December 31, 2025, the adjustment included intangible asset impairment charges for Otezla®. For the twelve months ended December 31, 2024, the adjustment included impairment charges for in-process R&D assets related to our Teneobio, Inc. acquisition from 2021.

(e)						For the three and twelve months ended December 31, 2025 and 2024, the adjustments related primarily to our BeOne Medicines Ltd. equity fair value adjustment.

(f)						The tax effect of the adjustments between our GAAP and non-GAAP results takes into account the tax treatment and related tax rate(s) that apply to each adjustment in the applicable tax jurisdiction(s). Generally, the tax impact of adjustments, including the amortization of intangible assets and acquired inventory, gains and losses on our investments in equity securities and expenses related to restructuring and cost-savings initiatives, depends on whether the amounts are deductible in the respective tax jurisdictions and the applicable tax rate(s) in those jurisdictions. Due to these factors, the effective tax rate for the adjustments to our GAAP income before income taxes for the three and twelve months ended December 31, 2025, was 19.8% and 18.0%, respectively, compared to 20.7% and 19.4%, respectively, for the corresponding periods of the prior year.

(g)						The adjustments related to certain acquisition-related, prior-period and other items excluded from GAAP earnings.
