THOUSAND OAKS, Calif., May 1, 2025 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced financial results for the first quarter of 2025. "Demand for our products was strong globally in the first quarter. Ongoing new product launches and successful Phase 3 trial results for several products make us feel confident in our long-term growth prospects," said Robert A. Bradway, chairman and chief executive officer. Key results include: For the first quarter, total revenues increased 9% to $8.1 billion in comparison to the first quarter of 2024. Product sales grew 11%, primarily driven by 14% volume growth, partially offset by 6% lower net selling price. U.S. sales grew 14%. Fourteen products delivered at least double-digit sales growth in the first quarter, including Repatha® (evolocumab), BLINCYTO® (blinatumomab), TEZSPIRE® (tezepelumab-ekko), EVENITY® (romosozumab-aqqg), TAVNEOS® (avacopan) and UPLIZNA® (inebilizumab-cdon). Our launch of IMDELLTRA ® (tarlatamab-dlle) generated $81 million of sales in the quarter and the Phase 3 confirmatory study demonstrated improved overall survival compared to chemotherapy. IMDELLTRA ® launched in Japan in April 2025. GAAP earnings per share (EPS) were $3.20 for the first quarter of 2025 compared with a GAAP loss per share of $0.21 for the first quarter of 2024, resulting from an unrealized gain on our BeiGene, Ltd. equity investment during the first quarter of 2025 compared to an unrealized loss during the prior year period, partially offset by an Otezla® intangible asset impairment charge of $800 million recorded during the first quarter of 2025. GAAP operating income increased from $1.0 billion to $1.2 billion, and GAAP operating margin increased 1.1 percentage points to 15.0%. Non-GAAP EPS increased 24% from $3.96 to $4.90, driven by higher revenues, partially offset by higher operating expenses. Non-GAAP operating income increased from $3.1 billion to $3.6 billion and non-GAAP operating margin increased 2.5 percentage points to 45.7%. The Company generated $1.0 billion of free cash flow in the first quarter of 2025 versus $0.5 billion in the first quarter of 2024. This increase reflects an $800 million tax deposit made in the first quarter of 2024 and current quarter business performance, partially offset by timing of working capital items and higher capital expenditures. References in this release to "non-GAAP" measures, measures presented "on a non-GAAP basis," and "free cash flow" (computed by subtracting capital expenditures from operating cash flow) refer to non-GAAP financial measures. Adjustments to the most directly comparable GAAP financial measures and other items are presented in the attached reconciliations. Refer to Non-GAAP Financial Measures below for further discussion.

Non-GAAP Financial Measures In this news release, management has presented its operating results for the first quarters 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 2025 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 first quarters of 2025 and 2024. FCF is computed by subtracting capital expenditures from operating cash flow, each as determined in accordance with GAAP. 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 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 BeiGene, Ltd. or Kyowa Kirin Co., Ltd.), the performance of Otezla® (apremilast), our acquisitions of ChemoCentryx, Inc. 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. There can be no guarantee that we will be able to realize any of the strategic benefits, synergies or opportunities arising from the Horizon acquisition, and such benefits, synergies or opportunities may take longer to realize than expected. We may not be able to successfully integrate Horizon, and such integration may take longer, be more difficult or cost more than expected. 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. CONTACT: Amgen, Thousand Oaks Elissa Snook, 609-251-1407 (media) Justin Claeys, 805-313-9775 (investors) Our GAAP diluted EPS guidance does not include the effect of GAAP adjustments triggered by events that may occur subsequent to this press release such as acquisitions, asset impairments, litigation, changes in fair value of our contingent consideration obligations and changes in fair value of our equity investments.
