AMGEN REPORTS SECOND QUARTER 2025 FINANCIAL RESULTS

THOUSAND OAKS, Calif. (Aug. 5, 2025) - Amgen (NASDAQ:AMGN) today announced financial results for the second quarter of 2025.

“We're delivering strong performance and reaching more patients with innovative medicines and biosimilars that address serious diseases. We continue to invest in science that enables longer, healthier lives and supports sustainable, long-term growth,” said Robert A. Bradway, chairman and chief executive officer.

Key results include:

•For the second quarter, total revenues increased 9% to $9.2 billion in comparison to the second quarter of 2024.

◦Product sales grew 9%, driven by 13% volume growth, partially offset by 3% lower net selling price.

◦Fifteen products delivered at least double-digit sales growth in the second quarter, including Repatha® (evolocumab), EVENITY® (romosozumab-aqqg), IMDELLTRA® (tarlatamab-dlle)/IMDYLLTRA™ (tarlatamab), BLINCYTO® (blinatumomab), TEZSPIRE® (tezepelumab-ekko), UPLIZNA® (inebilizumab-cdon), and TAVNEOS® (avacopan).

•GAAP earnings per share (EPS) increased 92% from $1.38 to $2.65, primarily driven by higher revenues.

◦GAAP operating income increased from $1.9 billion to $2.7 billion, and GAAP operating margin increased 6.6 percentage points to 30.3%.

•Non-GAAP EPS increased 21% from $4.97 to $6.02, primarily driven by higher revenues, partially offset by higher operating expenses.

◦Non-GAAP operating income increased from $3.9 billion to $4.3 billion, and non-GAAP operating margin increased 0.7 percentage points to 48.9%.

•The Company generated $1.9 billion of free cash flow in the second quarter of 2025 versus $2.2 billion in the second quarter of 2024, driven by 2024 tax payments deferred to 2025 and higher capital expenditures, partially offset by business performance.

Product Sales Performance

General Medicine

•Repatha® (evolocumab) sales increased 31% year-over-year to $696 million in the second quarter, driven by 36% volume growth, partially offset by unfavorable changes to estimated sales deductions.

•EVENITY® (romosozumab-aqqg) sales increased 32% year-over-year to $518 million in the second quarter, primarily driven by volume growth.

•Prolia® (denosumab) sales decreased 4% year-over-year to $1.1 billion in the second quarter, driven by lower net selling price. For 2025, we expect sales erosion driven by biosimilar competition in the second half of the year, as biosimilars have now launched in the U.S. market.

Operating Expense, Operating Margin and Tax Rate Analysis

On a GAAP basis:

•Total Operating Expenses increased 1% year-over-year for the second quarter. Cost of Sales as a percentage of product sales decreased 5.9 percentage points driven by lower amortization expense from the fair value step-up of inventory acquired from Horizon and lower manufacturing costs, partially offset by higher profit share expense and changes in our sales mix. Research & Development (R&D) expenses increased 21% driven by investments in later-stage clinical programs, including those related to MariTide, for which four Phase 3 studies are underway. Selling, General & Administrative (SG&A) expenses decreased 5% driven by lower commercial product-related expenses and lower Horizon acquisition-related expenses. Other operating expenses include litigation expenses.

•Operating Margin as a percentage of product sales increased 6.6 percentage points in the second quarter to 30.3%.

•Tax Rate increased 2.7 percentage points in the second quarter due to the change in earnings mix, including lower amortization expense from the fair value step-up of inventory acquired from Horizon and current year net unfavorable items, as compared to the prior year.

On a non-GAAP basis:

•Total Operating Expenses increased 8% year-over-year for the second quarter. Cost of Sales as a percentage of product sales increased 0.2 percentage points driven by higher profit share expense and changes in our sales mix, partially offset by lower manufacturing costs. R&D expenses increased 18% driven by investments in later-stage clinical programs, including those related to MariTide, for which four Phase 3 studies are underway. SG&A expenses decreased 2% primarily driven by lower commercial product-related expenses.

•Operating Margin as a percentage of product sales increased 0.7 percentage points in the second quarter to 48.9%.

•Tax Rate decreased 0.7 percentage points in the second quarter due to the change in earnings mix.

•XALute, a Phase 3 study of xaluritamig, is enrolling patients with metastatic castrate resistant prostate cancer (mCRPC) who have previously been treated with taxane-based chemotherapy.

•A Phase 1 study of xaluritamig monotherapy is ongoing in patients with mCRPC who have not yet received taxane-based chemotherapy and is ongoing in patients with mCPRC who have previously received taxane-based chemotherapy in a fully outpatient treatment setting to further improve administration convenience. This study continues to enroll mCRPC patients into a combination treatment of xaluritamig and abiraterone.

•A Phase 1b study of neoadjuvant xaluritamig therapy prior to radical prostatectomy is enrolling patients with newly diagnosed localized intermediate or high‐risk prostate cancer.

•A Phase 1b study of xaluritamig is enrolling patients with high-risk biochemically recurrent prostate cancer after definitive therapy.

Bemarituzumab

•Bemarituzumab is a first-in-class fibroblast growth factor receptor 2b (FGFR2b) targeting monoclonal antibody.

•In June, the Company announced the Phase 3 FORTITUDE-101 clinical trial of first-line bemarituzumab plus chemotherapy (mFOLFOX6) met its primary endpoint of OS at a pre-specified interim analysis:

◦Bemarituzumab plus chemotherapy demonstrated a statistically significant and clinically meaningful improvement in OS as compared to placebo plus chemotherapy in patients with unresectable locally advanced or metastatic gastric or gastroesophageal junction cancer with FGFR2b overexpression and who are non-HER2 positive. FGFR2b overexpression was defined as 2+/3+ staining in ≥10% of tumor cells by centrally performed immunohistochemistry testing.

◦The most common treatment-emergent adverse events (>25%) in patients treated with bemarituzumab plus chemotherapy were reduced visual acuity, punctate keratitis, anemia, neutropenia, nausea, corneal epithelium defect and dry eye. While ocular events were consistent with the Phase 2 experience and observed in both arms, they occurred with greater frequency and severity in the Phase 3 bemarituzumab arm.

◦Detailed results from FORTITUDE 101 will be shared at a future medical meeting.

•FORTITUDE-102, a Phase 1b/3 study of bemarituzumab plus chemotherapy and nivolumab, is ongoing in patients with first-line gastric cancer. Phase 3 data readout is anticipated in H2 2025/H1 2026.

•FORTITUDE-301, a Phase 1b/2 basket study of bemarituzumab monotherapy, is ongoing in patients with solid tumors with FGFR2b overexpression.

AMG 193

•AMG 193 is a first-in-class small molecule methylthioadenosine (MTA)-cooperative protein arginine methyltransferase 5 (PRMT5) inhibitor.

•A Phase 2 study of AMG 193 is enrolling patients with methylthioadenosine phosphorylase (MTAP)-null previously treated advanced non-small cell lung cancer (NSCLC).

•A Phase 1/1b/2 study of AMG 193 is enrolling patients with advanced MTAP-null solid tumors in the dose-expansion portion of the study.

•A Phase 1b study of AMG 193 alone or in combination with other therapies is enrolling patients with advanced MTAP-null thoracic malignancies.

•A Phase 1b study of AMG 193 in combination with other therapies is enrolling patients with advanced MTAP-null gastrointestinal, biliary tract, or pancreatic cancers.

Kyprolis

•In May, the FDA granted pediatric exclusivity to Kyprolis for studies conducted under a Written Request and approved updates to the "Pediatric Use" subsection of the Kyprolis prescribing information.

LUMAKRAS/LUMYKRAS

•In May, the FDA granted Breakthrough Therapy Designation to LUMAKRAS in combination with Vectibix and FOLFIRI for the first-line treatment of patients with KRAS G12C-mutated metastatic colorectal cancer (CRC), as determined by an FDA-approved test. This is the third Breakthrough Therapy Designation granted by the FDA for LUMAKRAS.

•CodeBreaK 301, a Phase 3 study of LUMAKRAS in combination with Vectibix and FOLFIRI vs. FOLFIRI with or without bevacizumab-awwb, is enrolling patients with first-line KRAS G12C–mutated metastatic CRC.

•CodeBreaK 202, a Phase 3 study of LUMAKRAS plus chemotherapy vs. pembrolizumab plus chemotherapy, is enrolling patients with first-line KRAS G12C–mutated and PD-L1 negative advanced NSCLC.

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. 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.

AMGEN REPORTS SECOND QUARTER 2025 FINANCIAL RESULTS

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

AMGEN REPORTS SECOND QUARTER 2025 FINANCIAL RESULTS

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.

(d)						For the three and six months ended June 30, 2025 and 2024, the adjustments related primarily to our BeOne Medicines Ltd. equity fair value adjustment.

(e)						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 six months ended June 30, 2025, was 18.0% and 18.4%, respectively, compared to 17.7% and 15.7%, respectively, for the corresponding periods of the prior year.

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