AMGEN INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2025

(Unaudited)

1. Summary of significant accounting policies

Business

Amgen Inc. (including its consolidated subsidiaries, referred to as “Amgen,” “the Company,” “we,” “our” or “us”) is a global biotechnology pioneer that discovers, develops, manufactures and delivers innovative human therapeutics. We operate our business in one operating segment: human therapeutics. See Note 2, Segment and other information.

Basis of presentation

The interim unaudited financial information for the three and nine months ended September 30, 2025 and 2024, has been prepared in accordance with GAAP and includes all adjustments (consisting of only normal, recurring adjustments unless otherwise indicated) that Amgen considers necessary for a fair presentation, in all material respects, of its condensed consolidated results of operations for those periods. Interim results are not necessarily indicative of results for the full fiscal year.

The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2024, and with the condensed consolidated financial statements and the notes thereto contained in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025.

Principles of consolidation

The condensed consolidated financial statements include the accounts of Amgen and its majority-owned subsidiaries. In determining whether we are the primary beneficiary of a variable interest entity, we consider whether we have both the power to direct activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. We do not have any significant interests in any variable interest entities of which we are the primary beneficiary. All material intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to prior periods in the condensed consolidated financial statements and accompanying notes to conform with the current presentation.

Use of estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates.

Property, plant and equipment, net

Property, plant and equipment is recorded at historical cost, net of accumulated depreciation and amortization of $ 11.0 billion and $ 10.4 billion as of September 30, 2025 and December 31, 2024, respectively.

Recent accounting pronouncements not yet adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to improve income tax disclosure requirements by requiring more detailed information in several income tax disclosures, such as enhancing disclosure of income taxes paid and requiring disaggregation of the effective income tax rate reconciliation. The standard is effective for public business entities such as Amgen for annual periods beginning after December 15, 2024. Early adoption is permitted, and entities may apply the standard prospectively or retrospectively. We expect the adoption of this new standard to result in incremental disclosures to the notes to our consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to improve disclosures about a public business entity’s expenses by requiring disaggregated disclosures of certain types of expenses, including purchases of inventory, employee compensation, depreciation, intangible amortization and depletion, as applicable, for each income statement caption that includes those expenses. In addition, the standard will require entities to define and disclose total selling expenses. The standard is effective for public business entities such as Amgen for annual periods beginning after

December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted, and entities may apply the standard prospectively or retrospectively. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting for software costs, including updating guidance on the recognition and measurement of costs incurred in connection with development and implementation activities related to internal-use software. The standard is effective for all entities for annual periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted, and entities may apply the standard prospectively or retrospectively. We are currently evaluating the impact of adopting this new standard on our consolidated financial statements and related disclosures.

2. Segment and other information

The human therapeutics segment is engaged in the discovery, development, manufacturing and delivery of innovative medicines to fight some of the world’s toughest diseases. The Company’s Chief Executive Officer has been identified as the chief operating decision maker (CODM). The CODM manages and allocates resources on a consolidated basis. The determination of a single segment is consistent with the financial information regularly reviewed by the CODM for purposes of evaluating performance and allocating resources, which is reviewed on a consolidated basis.

As the Company’s CODM evaluates the financial performance of the Company’s human therapeutics segment on a consolidated basis, the measure of segment performance is net income, as reflected in the Condensed Consolidated Statements of Income. The CODM uses net income to allocate resources on a consolidated basis, which enables the CODM to both assess the overall level of resources available and optimize the distribution of resources across functions, therapeutic areas, regions and R&D programs in line with our long-term corporate-wide strategic goals. In addition, the CODM may also evaluate financial performance based on net income adjusted for certain items that are unusual and non-recurring. As the Company manages its assets on a consolidated basis, the measure of segment assets is total assets, as reflected in the Condensed Consolidated Balance Sheets. See Note 6, Investments, for further information regarding equity method investments, and Net cash used in investing activities in the Condensed Consolidated Statements of Cash Flows for further information regarding capital expenditures.

The following table provides segment revenues, significant segment expenses, other segment items and reported segment net income for the Company’s one reportable segment, as well as a reconciliation of segment net income to the Company’s total consolidated net income for the three and nine months ended September 30, 2025 and 2024 (in millions):

(1) During the three months ended September 30, 2025 and 2024, amortization of our finite-lived intangible assets was $ 1.1 billion and $ 1.2 billion, respectively. During the nine months ended September 30, 2025 and 2024, amortization of our finite-lived intangible assets was $ 3.4 billion and $ 3.6 billion, respectively. Amortization of intangible assets is primarily included in Cost of sales in the Condensed Consolidated Statements of Income. In addition, during the three months ended September 30, 2025 and 2024, we recognized depreciation and right-of-use asset amortization of $ 232 million and $ 198 million, respectively. During the nine months ended September 30, 2025 and 2024, we recognized depreciation and right-of-use asset amortization of $ 661 million and $ 601 million, respectively.

(2) During the three months ended September 30, 2025 and 2024, manufacturing cost of sales included amortization of step-up to fair value of inventory acquired in business combinations of $ 338 million and $ 661 million, respectively. During the nine months ended September 30, 2025 and 2024, manufacturing cost of sales included amortization of step-up to fair value of inventory acquired in business combinations of $ 1.0 billion and $ 2.0 billion, respectively.

(3) Other segment items included in Segment net income primarily consisted of fair value adjustments on equity securities (see Note 6, Investments) and net impairment charges on intangible assets (see Note 8, Goodwill and other intangible assets).

3. Revenues

We operate our business in one operating segment, which also represents one reportable segment: human therapeutics. Therefore, results of our operations are reported on a consolidated basis for purposes of segment reporting, consistent with internal management reporting. Revenues by product and by geographic area, based on customers’ locations, are presented below. A substantial portion of ROW product sales relates to products sold in Europe.

_______

(1) TEZSPIRE is marketed by our collaborator AstraZeneca outside the United States.

(2) Consists of product sales of our non-principal products.

(3) Hedging gains and losses, which are included in product sales, were not material for the three and nine months ended September 30, 2025 and 2024.

4. Income taxes

The effective tax rates for the three and nine months ended September 30, 2025 were 18.0 % and 14.5 %, respectively, compared with 8.7 % and 9.5 %, respectively, for the corresponding periods in the prior year.

The increase in our effective tax rate for the three months ended September 30, 2025, was primarily due to the change in earnings mix, including lower amortization expense from the fair value step-up of inventory acquired from Horizon. The increase in our effective tax rate for the nine months ended September 30, 2025, was primarily due to the change in earnings mix, including the net unrealized gains on equity investments in the first nine months of 2025 compared to those in the prior-year period (see Note 6, Investments) and partially offset by the year-to-date Otezla impairment charges and related tax impacts (see Note 8, Goodwill and other intangible assets) . The effective tax rates differ from the federal statutory rate primarily due to the impact of the jurisdictional mix of income and expenses. Substantially all of the benefit to our effective tax rate from foreign earnings results from locations in which the Company has significant manufacturing operations, including Singapore, Ireland and Puerto Rico, a territory of the United States that is treated as a foreign jurisdiction for U.S. tax purposes. Our operations in Puerto Rico are subject to tax incentive grants through 2050 and the Company’s operations in Singapore are subject to a tax incentive grant through 2036. Effective January 1, 2024, selected individual countries, including the United Kingdom and EU member countries, have enacted the global minimum tax agreement. Additional countries, including Singapore, enacted the minimum tax agreement effective January 1, 2025. Singapore’s enactment of the agreement applies irrespective of the Company’s incentive grant. Due to the currently enacted scope of the agreement, the Company and its subsidiaries are now subject to a 15% minimum tax rate on adjusted financial statement income. Our foreign earnings are also subject to U.S. tax at a reduced rate of 10.5%.

On July 4, 2025, OB3 was enacted in the United States. OB3 has various provisions, including the permanent extension of certain expiring provisions of the 2017 Tax Act, and modifications to the international tax framework. The legislation has multiple effective dates, with certain provisions effective in 2026 and beyond. The impact of these changes on our deferred tax assets and liabilities was recorded in the third quarter of 2025 and did not have a material effect on our effective tax rate or on our condensed consolidated financial statements.

One or more of our legal entities file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and certain foreign jurisdictions. Our income tax returns are routinely examined by tax authorities in those jurisdictions. Significant disputes can arise and have arisen with tax authorities involving issues regarding the timing and amount of deductions, the use of tax credits and allocations of income and expenses among various tax jurisdictions because of differing interpretations of tax laws, regulations and relevant facts. Tax authorities, including the IRS, are becoming more aggressive and are particularly focused on such matters.

In 2017, we received an RAR and a modified RAR from the IRS for the years 2010–2012, proposing significant adjustments that primarily relate to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico. We disagreed with the proposed adjustments and calculations and pursued resolution with the IRS appeals office, but were unable to reach a resolution. In July 2021, we filed a petition in the U.S. Tax Court to contest two duplicate Statutory Notices of Deficiency (Notices) for the years 2010–2012 that we received in May and July 2021, which seek to increase our U.S. taxable income for the years 2010–2012 by an amount that would result in additional federal tax of approximately $ 3.6 billion, plus interest. Any additional tax that could be imposed for the years 2010–2012 would be reduced by up to approximately $ 900 million of repatriation tax previously accrued and paid on our foreign earnings.

In 2020, we received an RAR and a modified RAR from the IRS for the years 2013–2015, also proposing significant adjustments that primarily relate to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and calculations and pursued resolution with the IRS appeals office, but were unable to reach a resolution. In July 2022, we filed a petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we previously reported receiving in April 2022 that seeks to increase our U.S. taxable income for the years 2013–2015 by an amount that would result in additional federal tax of approximately $ 5.1 billion, plus interest. In addition, the Notice asserts penalties of approximately $ 2.0 billion. Any additional tax that could be imposed for the years 2013–2015 would be reduced by up to approximately $ 2.2 billion of repatriation tax previously accrued and paid on our foreign earnings.

We firmly believe that the IRS positions set forth in the 2010–2012 and 2013–2015 Notices are without merit. We are contesting the 2010–2012 and 2013–2015 Notices through the judicial process. The two cases were consolidated in the U.S. Tax Court on December 19, 2022. The trial began on November 4, 2024 and concluded on January 17, 2025. The parties filed opening post-trial briefs on June 13, 2025, and the Court held oral argument on July 16, 2025. The parties filed post-trial reply briefs on October 10, 2025. The Company expects a decision from the U.S. Tax Court no earlier than the second half of 2026.

We are currently under examination by the IRS for the years 2016–2018 with respect to issues similar to those for the 2010 through 2015 period. We expect that the IRS will begin its audit of 2019-2022 in 2025 or early 2026, and we believe that it may seek to continue to audit similar issues related to the allocation of income between the United States and our foreign jurisdictions. In addition, we are under examination by a number of state and foreign tax jurisdictions.

Final resolution of these complex matters is not likely within the next 12 months. We continue to believe our accrual for income tax liabilities is appropriate based on past experience, interpretations of tax law, application of the tax law to our facts and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes and uncertain resolution of these matters, the ultimate outcome of any tax matters may result in payments substantially greater than amounts accrued and could have a material adverse impact on our condensed consolidated financial statements.

During the three and nine months ended September 30, 2025, the gross amounts of our UTBs increased by $ 45 million and $ 145 million, respectively, as a result of tax positions taken during the current year. Substantially all of the UTBs as of September 30, 2025, if recognized, would impact our effective tax rate.

5. Earnings per share

The computation of basic EPS is based on the weighted-average number of our common shares outstanding. The computation of diluted EPS is based on the weighted-average number of our common shares outstanding and dilutive potential common shares, which primarily include shares that may be issued under our stock option, restricted stock and performance unit award programs (collectively, dilutive securities), as determined by using the treasury stock method.

The computations for basic and diluted EPS were as follows (in millions, except per-share data):


	Three months ended September 30,				Nine months ended September 30,
	2025		2024		2025		2024
Income (Numerator):
Net income for basic and diluted EPS	$	3,216	$	2,830	$	6,378	$	3,463

Shares (Denominator):
Weighted-average shares for basic EPS	538		537		538		537
Effect of dilutive securities	4		5		4		4
Weighted-average shares for diluted EPS	542		542		542		541

Basic earnings per share	$	5.98	$	5.27	$	11.86	$	6.45
Diluted earnings per share	$	5.93	$	5.22	$	11.77	$	6.40

For the three and nine months ended September 30, 2025 and 2024, the number of antidilutive employee stock-based awards excluded from the computation of diluted EPS was not significant.

6. Investments

Available-for-sale investments

The amortized cost, gross unrealized gains, gross unrealized losses and fair values of interest-bearing securities, which are classified as available for sale, by type of security were as follows (in millions):


Types of securities as of September 30, 2025	Amortized cost		Gross unrealized gains		Gross unrealized losses		Fair values

U.S. Treasury bills	$	998	$	—	$	—	$	998









Money market mutual funds	7,581		—		—		7,581
Other short-term interest-bearing securities	129		—		—		129
Total interest-bearing securities	$	8,708	$	—	$	—	$	8,708


Types of securities as of December 31, 2024	Amortized cost		Gross unrealized gains		Gross unrealized losses		Fair values

U.S. Treasury bills	$	997	$	—	$	—	$	997









Money market mutual funds	10,354		—		—		10,354
Other short-term interest-bearing securities	135		—		—		135
Total interest-bearing securities	$	11,486	$	—	$	—	$	11,486

The fair values of interest-bearing securities by location in the Condensed Consolidated Balance Sheets were as follows (in millions):


Condensed Consolidated Balance Sheets locations	September 30, 2025		December 31, 2024
Cash and cash equivalents	$	8,708	$	11,486

Total interest-bearing securities	$	8,708	$	11,486

Cash and cash equivalents in the above table excludes bank account cash of $ 737 million and $ 487 million as of September 30, 2025 and December 31, 2024, respectively.

All interest-bearing securities as of September 30, 2025 and December 31, 2024, mature in one year or less. For the three months ended September 30, 2025 and 2024, interest income on these investments was $ 99 million and $ 126 million, respectively. For the nine months ended September 30, 2025 and 2024, interest income on these investments was $ 311 million and $ 394 million, respectively.

For the three and nine months ended September 30, 2025 and 2024, realized gains and losses on interest-bearing securities were not material and were recorded in Other income, net, in the Condensed Consolidated Statements of Income. The cost of securities sold is based on the specific-identification method.

The primary objective of our investment portfolio is to maintain safety of principal, prudent levels of liquidity and acceptable levels of risk. Our investment policy limits interest-bearing security investments to certain types of debt and money market instruments issued by institutions with investment-grade credit ratings, and it places restrictions on maturities and concentration by asset class and issuer.

Equity securities

BeOne Medicines Ltd.

As of September 30, 2025 and December 31, 2024, the fair values of our investment in BeOne were $ 6.5 billion and $ 3.5 billion, respectively, which were included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three months ended September 30, 2025 and 2024, we recorded unrealized gains of $ 1.9 billion and $ 1.6 billion, respectively. During the nine months ended September 30, 2025 and 2024, we recorded unrealized gains of $ 3.0 billion and $ 836 million, respectively. These unrealized gains were recognized in Other income, net, in the Condensed Consolidated Statements of Income.

Subject to certain exceptions or otherwise agreed to by BeOne, while Amgen holds at least 5.0 % of BeOne’s outstanding common stock, (A) we may only sell our BeOne equity investment via: (i) a registered public offering, (ii) a sale under Rule

144 of the Securities Act of 1933 (the “Securities Act”) or (iii) a private sale exempt from registration requirements under the Securities Act, and (B) we may not sell more than 5.0 % of BeOne’s outstanding common stock in any rolling 12-month period.

Other equity securities

Excluding our equity investments in BeOne (discussed above) and Neumora (discussed below), we held investments in other equity securities with readily determinable fair values (publicly traded securities) of $ 300 million and $ 314 million as of September 30, 2025 and December 31, 2024, respectively, which were included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three and nine months ended September 30, 2025, and 2024, net unrealized gains on these publicly traded securities were not material. Additionally, net realized gains and losses on sales of publicly traded securities for the three and nine months ended September 30, 2025 and 2024, were not material.

We held investments of $ 339 million and $ 319 million in equity securities without readily determinable fair values as of September 30, 2025 and December 31, 2024, respectively, which were included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three and nine months ended September 30, 2025 and 2024, upward and downward adjustments on these securities were not material. Adjustments were based on observable price transactions. Net realized gains and losses on sales of securities without readily determinable fair values for the three and nine months ended September 30, 2025 and 2024, were not material.

Equity method investments

Neumora Therapeutics, Inc.

As of September 30, 2025 and December 31, 2024, our ownership interest in Neumora was approximately 21.8 % and 21.9 %, respectively, and the fair values of our investment were $ 64 million and $ 375 million, respectively, which were included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. Although our equity investment qualifies us for the equity method of accounting, we have elected the fair value option to account for our investment. Under the fair value option, changes in the fair value of the investment are recognized through earnings in Other income, net, in the Condensed Consolidated Statements of Income each reporting period. See Note 11, Fair value measurement. We believe the fair value option best reflects the economics of the underlying transaction. During the three months ended September 30, 2025 and 2024, we recognized unrealized gains of $ 38 million and $ 119 million, respectively, and during the nine months ended September 30, 2025 and 2024, we recognized unrealized losses of $ 311 million and $ 136 million, respectively.

We are contractually restricted from selling more than 5.0 % of Neumora’s outstanding common stock in any rolling 12-month period for as long as we hold at least 10.0 % of their outstanding common stock, subject to certain exceptions or otherwise agreed to by Neumora.

Limited partnerships

We held limited partnership investments of $ 246 million and $ 262 million as of September 30, 2025 and December 31, 2024, respectively, which were included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. These investments, which are primarily investment funds of early-stage biotechnology companies, are accounted for by using the equity method of accounting and are measured by using our proportionate share of the net asset values of the underlying investments held by the limited partnerships as a practical expedient. These investments are typically redeemable only through distributions upon liquidation of the underlying assets. As of September 30, 2025, we had $ 142 million of unfunded additional commitments to be made for these investments during the next several years. For the three and nine months ended September 30, 2025 and 2024, net unrealized gains and losses recognized from our limited partnership investments were not material.

Developed-product-technology rights consists of rights related to marketed products acquired in business acquisitions. Licensing rights primarily consists of contractual rights to receive future milestone, royalty and profit-sharing payments; capitalized payments to third parties for milestones related to regulatory approvals to commercialize products; and upfront payments associated with royalty obligations for marketed products. R&D technology rights pertains to technologies used in R&D that have alternative future uses. Marketing-related rights primarily consists of rights related to the sale and distribution of marketed products.

In January 2025, as part of the IRA, the Company’s product Otezla was selected by CMS for Medicare price setting that will be applicable beginning on January 1, 2027. The earlier than anticipated selection resulted in a decrease in the estimated future cash flows for the product in the United States. This selection represented a triggering event that required the Company to evaluate the underlying developed-product-technology rights for impairment. In the first quarter of 2025, the Company utilized a discounted cash flow analysis based on Level 3 inputs, including estimated product sales, operating expenses and a discount rate, that resulted in an intangible asset fair value of $ 4.0 billion, which was lower than the carrying value of $ 4.8 billion, and a partial impairment of $ 800 million. In the third quarter of 2025, new facts and circumstances, primarily from the CMS price setting process, indicated a further triggering event that required the Company to evaluate the underlying developed-product-technology rights for impairment. A subsequent discounted cash flow analysis, prepared using the same Level 3 input framework and updated assumptions, resulted in a revised intangible asset fair value of $ 3.0 billion, which was lower than the carrying value of $ 3.4 billion, and an additional impairment of $ 400 million. The impairment charges of $ 400 million and $ 1.2 billion for three and nine months ended September 30, 2025, respectively, were recorded in Other operating expenses in the Condensed Consolidated Statements of Income. See Note 11, Fair value measurement.

IPR&D consists of R&D projects acquired in a business combination that are not complete at the time of acquisition due to remaining technological risks and/or lack of receipt of required regulatory approvals. We review IPR&D projects for impairment annually, whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable and upon the establishment of technological feasibility or regulatory approval. During the second quarter of 2025, the FDA approved UPLIZNA for the Immunoglobulin G4-related disease (IgG4-RD) indication, and commercialization commenced in the United States. As a result, the Company reclassified the related intangible asset with a gross carrying value of $ 350 million from IPR&D to developed-product-technology rights and began amortizing it on a straight-line basis over its estimated useful life of approximately 11 years from the date placed in service.

During the three months ended September 30, 2025 and 2024, we recognized amortization of our finite-lived intangible assets of $ 1.1 billion and $ 1.2 billion, respectively. During the nine months ended September 30, 2025 and 2024, we recognized amortization of our finite-lived intangible assets of $ 3.4 billion and $ 3.6 billion, respectively. Amortization of intangible assets is primarily included in Cost of sales in the Condensed Consolidated Statements of Income. As of September 30, 2025, the total estimated future amortization of our finite-lived intangible assets for the remaining three months ending December 31, 2025, and the years ending December 31, 2026, 2027, 2028, 2029 and 2030, was $ 0.9 billion, $ 3.6 billion, $ 3.5 billion, $ 2.8 billion, $ 2.3 billion and $ 2.2 billion, respectively.

11. Fair value measurement

To estimate the fair values of our financial assets and liabilities, we use valuation approaches within a hierarchy that maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing an asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is divided into three levels based on the sources of inputs as follows:


Level 1	—	Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access
Level 2	—	Valuations for which all significant inputs are observable either directly or indirectly—other than Level 1 inputs
Level 3	—	Valuations based on inputs that are unobservable and significant to the overall fair value measurement

The availability of observable inputs can vary among different types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, inputs used for measuring fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level of input used that is significant to the overall fair value measurement.

The fair values of each major class of the Company’s financial assets and liabilities measured at fair value on a recurring basis were as follows (in millions):


	Quoted prices in active markets for identical assets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)

Interest-bearing and equity securities

The fair values of our U.S. Treasury bills are determined by utilizing third-party pricing services, which obtain pricing data from active market makers and brokers. The fair values of our money market mutual funds and equity investments in publicly traded securities, including our equity investments in BeOne and Neumora, as of September 30, 2025 and December 31, 2024, are based on quoted market prices in active markets, with no valuation adjustment.

Derivatives

All of our foreign currency forward contracts, cross-currency swap contracts and interest rate swap contracts are with counterparties that have minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that uses an income-based industry-standard valuation model for which all significant inputs are observable either directly or indirectly. These inputs, as applicable, include foreign currency exchange rates, SOFR, swap rates, obligor credit default swap rates and cross-currency basis swap spreads. Certain inputs, when applicable, are at commonly quoted intervals. See Note 12, Derivative instruments.

Summary of the fair values of other financial instruments

Cash equivalents

The fair values of cash equivalents approximate their carrying values due to the short-term nature of such financial instruments.

Borrowings

We estimate the fair values of our fixed-rate debt by using Level 2 inputs. As of September 30, 2025 and December 31, 2024, the aggregate fair values of our fixed-rate debt were $ 51.2 billion and $ 54.9 billion, respectively, and the carrying values of our fixed-rate debt were $ 52.8 billion and $ 58.3 billion, respectively. The estimate of the fair value of our term loan approximates its carrying value as of September 30, 2025 and December 31, 2024, as this debt instrument bears interest at a floating rate.

During the nine months ended September 30, 2025 and 2024, there were no transfers of assets or liabilities between fair value measurement levels. Except with respect to the partial impairments of the Otezla intangible asset in the first and third quarters of 2025 as discussed in Note 8, Goodwill and other intangible assets, there were no material remeasurements of the fair values of assets and liabilities that are not measured at fair value on a recurring basis.

12. Derivative instruments

The Company is exposed to foreign currency exchange rate and interest rate risks related to its business operations. To reduce our risks related to such exposures, we use or have used certain derivative instruments, including foreign currency forward, foreign currency option, cross-currency swap, forward interest rate and interest rate swap contracts. We have designated certain of our derivatives as cash flow and fair value hedges; we also have derivatives not designated as hedges. We do not use derivatives for speculative trading purposes.

Cash flow hedges

We are exposed to possible changes in the values of certain anticipated foreign currency cash flows resulting from changes in foreign currency exchange rates primarily associated with our euro-denominated international product sales. The foreign currency exchange rate fluctuation exposure associated with cash inflows from our international product sales is partially offset by corresponding cash outflows from our international operating expenses. To further reduce our exposure, we enter into foreign currency forward contracts to hedge a portion of our projected international product sales up to a maximum of three years into the future; and at any given point in time, a higher percentage of nearer-term projected product sales is being hedged than in successive periods.

As of September 30, 2025 and December 31, 2024, we had outstanding foreign currency forward contracts with aggregate notional amounts of $ 7.7 billion and $ 7.2 billion, respectively. We have designated these foreign currency forward contracts, which are primarily euro based, as cash flow hedges. Accordingly, we record the unrealized gains and losses on these contracts in AOCI in the Condensed Consolidated Balance Sheets, and we reclassify them to Product sales in the Condensed Consolidated Statements of Income in the same periods during which the hedged transactions affect earnings.

To hedge our exposure to foreign currency exchange rate risk associated with certain of our long-term debt denominated in foreign currencies, we enter into cross-currency swap contracts. Under the terms of such contracts, we paid euros and pounds sterling and received U.S. dollars for the notional amounts at the inception of the contracts; and based on these notional amounts, we exchange interest payments at fixed rates over the terms of the contracts by paying U.S. dollars and receiving euros and pounds sterling. In addition, we will pay U.S. dollars to and receive euros and pounds sterling from the counterparties at the maturities of the contracts for these same notional amounts. The terms of these contracts correspond to the related hedged debt, thereby effectively converting the interest payments and principal repayment on the debt from euros and pounds sterling to U.S. dollars. We have designated these cross-currency swap contracts as cash flow hedges. Accordingly, the unrealized gains and losses on these contracts are recorded in AOCI in the Condensed Consolidated Balance Sheets and reclassified to Other income, net, in the Condensed Consolidated Statements of Income in the same periods during which the hedged debt affects earnings.

The notional amounts and interest rates of our cross-currency swaps as of September 30, 2025, were as follows (notional amounts in millions):

In connection with the anticipated issuance of long-term fixed-rate debt, we occasionally enter into forward interest rate contracts in order to hedge the variability in cash flows due to changes in the applicable U.S. Treasury rate between the time we enter into these contracts and the time the related debt is issued. Gains and losses on forward interest rate contracts, which are designated as cash flow hedges, are recognized in AOCI in the Condensed Consolidated Balance Sheets and are amortized into Interest expense, net, in the Condensed Consolidated Statements of Income over the terms of the associated debt issuances. Amounts recognized in connection with forward interest rate contracts during the nine months ended September 30, 2025 and 2024, and amounts expected to be recognized during the next 12 months are not material.

Unrealized gains and losses recognized in AOCI for our derivative instruments designated as cash flow hedges were as follows (in millions):


	Three months ended September 30,				Nine months ended September 30,
Derivatives in cash flow hedging relationships	2025		2024		2025		2024
Foreign currency forward contracts	$	123	$	( 238 )	$	( 592 )	$	87
Cross-currency swap contracts	( 50 )		80		196		50

Total unrealized gains (losses)	$	73	$	( 158 )	$	( 396 )	$	137

Fair value hedges

To achieve a desired mix of fixed-rate and floating-rate debt, we enter into interest rate swap contracts that qualify for and are designated as fair value hedges. These interest rate swap contracts effectively convert fixed-rate coupons to floating-rate SOFR-based coupons over the terms of the related hedge contracts. As of September 30, 2025 and December 31, 2024, we had interest rate swap contracts with aggregate notional amounts of $ 6.2 billion and $ 6.7 billion respectively, that hedge certain portions of our long-term debt. During the nine months ended September 30, 2025 there was a reduction in the aggregate notional amount of these contracts due to the termination of swaps that occurred in connection with the repayment of the 3.125 % 2025 Notes (see Note 9, Financing arrangements). In addition, we entered into $ 550 million of new interest rate swaps to hedge a portion of our 5.25 % 2033 Notes, resulting in an interest rate of SOFR plus 1.7 % on the $ 550 million hedged portion.

For interest rate swap contracts that qualify for and are designated as fair value hedges, we recognize in Interest expense, net, in the Condensed Consolidated Statements of Income the unrealized gain or loss on the derivative resulting from the change in fair value during the period, as well as the offsetting unrealized loss or gain of the hedged item resulting from the change in fair value during the period attributable to the hedged risk. If a hedging relationship involving an interest rate swap contract is terminated, the gain or loss realized on contract termination is recorded as an adjustment to the carrying value of the debt and amortized into Interest expense, net, over the remaining term of the previously hedged debt.

The hedged liabilities and related cumulative-basis adjustments for fair value hedges of those liabilities were recorded in the Condensed Consolidated Balance Sheets as follows (in millions):


	Carrying amounts of hedged liabilities (1)				Cumulative amounts of fair value hedging adjustments related to the carrying amounts of the hedged liabilities (2)
Condensed Consolidated Balance Sheets locations	September 30, 2025		December 31, 2024		September 30, 2025		December 31, 2024
Current portion of long-term debt	$	1,266	$	1,045	$	16	$	45
Long-term debt	$	4,670	$	5,152	$	( 175 )	$	( 388 )

____________

(1) Current portion of long-term debt includes $ 51 million and $ 56 million of carrying value with discontinued hedging relationships as of September 30, 2025 and December 31, 2024, respectively. Long-term debt includes $ 194 million and $ 232 million of carrying value with discontinued hedging relationships as of September 30, 2025 and December 31, 2024, respectively.

(2) Current portion of long-term debt includes $ 51 million and $ 56 million of hedging adjustments on discontinued hedging relationships as of September 30, 2025 and December 31, 2024, respectively. Long-term debt includes $ 94 million and $ 132 million of hedging adjustments on discontinued hedging relationships as of September 30, 2025 and December 31, 2024, respectively.

Impact of hedging transactions

The following tables summarize the amounts recorded in income and expense line items and the effects thereon from fair value and cash flow hedging, including discontinued hedging relationships (in millions):

__________

(1) Gains (losses) on hedged items do not exactly offset losses (gains) on the related designated hedging instruments due to amortization of the cumulative amounts of fair value hedging adjustments included in the carrying amount of the hedged debt for discontinued hedging relationships and the recognition of gains on terminated hedges when the corresponding hedged item was paid down in the period.

No portions of our cash flow hedge contracts were excluded from the assessment of hedge effectiveness. As of September 30, 2025, the amount of net losses on our foreign currency forward and cross-currency swap contracts expected to be reclassified out of AOCI and recognized into earnings during the next 12 months was not material.

Derivatives not designated as hedges

To reduce our exposure to foreign currency fluctuations in certain assets and liabilities denominated in foreign currencies, we enter into foreign currency forward contracts that are not designated as hedging transactions. Most of these exposures are hedged on a month-to-month basis. As of September 30, 2025 and December 31, 2024, the total notional amounts of these foreign currency forward contracts were $ 245 million and $ 148 million, respectively. Gains and losses recognized in earnings for our derivative instruments not designated as hedging instruments were not material for the three and nine months ended September 30, 2025 and 2024.

Fair values of derivatives

The fair values of derivatives included in the Condensed Consolidated Balance Sheets were as follows (in millions):


	Derivative assets			Derivative liabilities

Total derivatives		$	420		$	1,022

For additional information, see Note 11, Fair value measurement.

Our derivative contracts that were in liability positions as of September 30, 2025, contain certain credit-risk-related contingent provisions that would be triggered if (i) we were to undergo a change in control and (ii) our or the surviving entity’s creditworthiness deteriorates, which is generally defined as having either a credit rating that is below investment grade or a materially weaker creditworthiness after the change in control. If these events were to occur, the counterparties would have the right, but not the obligation, to close the contracts under early-termination provisions. In such circumstances, the counterparties could request immediate settlement of these contracts for amounts that approximate the then current fair values of the contracts. In addition, our derivative contracts are not subject to any type of master netting arrangement, and amounts due either to or from a counterparty under the contracts may be offset against other amounts due either to or from the same counterparty only if an event of default or termination, as defined, were to occur.

The cash flow effects of our derivative contracts in the Condensed Consolidated Statements of Cash Flows are primarily included in Net cash provided by operating activities, except for the settlement of notional amounts of cross-currency swaps, which are included in Net cash used in financing activities.

13. Contingencies and commitments

Contingencies

In the ordinary course of business, we are involved in various legal proceedings, government investigations and other matters that are complex in nature and have outcomes that are difficult to predict. See our Annual Report on Form 10-K for the year ended December 31, 2024, Part I, Item 1A. Risk Factors— Our business may be affected by litigation and government investigations. We describe our legal proceedings and other matters that are significant or that we believe could become significant in this footnote and in Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024; and in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025.

We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause an increase or decrease in the amount of the liability that has been accrued previously.

Our legal proceedings involve various aspects of our business and a variety of claims, some of which present novel factual allegations and/or unique legal theories. In each of the matters described in this filing, in which we could incur a liability, our opponents seek an award of a not-yet-quantified amount of damages or an amount that is not material. In addition, a number of the matters pending against us are at very early stages of the legal process, which in complex proceedings of the sort we face often extend for several years. As a result, none of the matters described in this filing, in which we could incur a liability, have progressed sufficiently through discovery and/or the development of important factual information and legal issues to enable us to estimate a range of possible loss, if any, or such amounts are not material. While it is not possible to accurately predict or determine the eventual outcomes of these matters, an adverse determination in one or more of these matters currently pending could have a material adverse effect on our consolidated results of operations, financial position or cash flows.

Certain recent developments concerning our legal proceedings and other matters are discussed below.

Item 2.			MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following MD&A is intended to assist the reader in understanding Amgen’s business. MD&A is provided as a supplement to, and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024, and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025. Our results of operations discussed in MD&A are presented in conformity with GAAP. Amgen operates in one operating segment: human therapeutics. Therefore, our results of operations are discussed on a consolidated basis.

Forward-looking statements

This report and other documents we file with the SEC contain forward-looking statements that are based on current expectations, estimates, forecasts and projections about us, our future performance, our business, our beliefs and our management’s assumptions. In addition, we, or others on our behalf, may make forward-looking statements in press releases, written statements or our communications and discussions with investors and analysts in the normal course of business through meetings, webcasts, phone calls and conference calls. Such words as “expect,” “anticipate,” “outlook,” “could,” “target,” “project,” “intend,” “plan,” “believe,” “seek,” “estimate,” “should,” “may,” “assume” and “continue” as well as variations of such words and similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance, and they involve certain risks, uncertainties and assumptions that are difficult to predict. We describe our respective risks, uncertainties and assumptions that could affect the outcome or results of operations in Item 1A. Risk Factors in Part II herein and in Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2024, and in Part II, Item 1A.

Overview

Amgen Inc. (including its subsidiaries, referred to as “Amgen,” “the Company,” “we,” “our” or “us”) discovers, develops, manufactures and delivers innovative medicines to fight some of the world’s toughest diseases. We focus on areas of high unmet medical need and leverage our expertise to strive for solutions that dramatically improve people’s lives, while also reducing the social and economic burden of disease. We helped launch the biotechnology industry more than 40 years ago and have grown to be one of the world’s leading independent biotechnology companies. Our robust pipeline includes potential first-in-class medicines at all stages of development.

Our principal products are Prolia, Repatha, ENBREL, Otezla, XGEVA, EVENITY, TEPEZZA, BLINCYTO, Nplate, KYPROLIS, Aranesp, TEZSPIRE, KRYSTEXXA and Vectibix. We also market a number of other products, including but not limited to MVASI, PAVBLU, AMJEVITA/AMGEVITA, UPLIZNA, IMDELLTRA/IMDYLLTRA, TAVNEOS, RAVICTI, Neulasta, LUMAKRAS/LUMYKRAS, Parsabiv, Aimovig, WEZLANA/WEZENLA and PROCYSBI.

Tariffs and trade protection measures

Numerous tariffs and trade protection measures have been proposed, and in a number of cases, implemented by the United States and other countries. These tariffs and trade protection measures include the universal 10% tariff on goods imported into the United States, the July Tariff EOs imposing additional country-specific tariffs for more than 60 countries, the trade framework with the EU effective September 2025 that imposes a baseline 15% tariff on most goods from the EU, bilateral trade deals with certain other countries such as Vietnam, Japan and the United Kingdom for special tariff rates, China’s country-specific tariff that is expected to become effective on November 10, 2025, and retaliatory tariffs on U.S. goods. These tariffs and trade protection measures may adversely affect our business and results of operations. Further, there are a number of proposed and potential sector-specific tariffs on our industry that are in development. See Part II, Item 1A. Risk Factors —Global economic conditions may negatively affect us and may magnify certain risks that affect our business, of this Quarterly Report on Form 10-Q for further discussion. While existing tariffs have not had a material adverse effect on our results of operations for the nine months ended September 30, 2025, certain tariffs that are currently in effect, or anticipated to take effect in the future, are expected to further increase our manufacturing and operating expenses in future quarters, including the cost to deliver products to markets, cost of sourcing materials for the manufacturing of our products and cost of materials used in our R&D activities. Furthermore, such tariffs may increasingly affect the cost to expand our manufacturing capacity in the United

States, including increased construction costs and/or delays in construction for our Ohio and North Carolina facilities. Additionally, retaliatory tariffs imposed by other countries may adversely affect our business, operations and delivery and launches of products in such markets, including the performance of our collaborations in such markets. However, the degree of adverse effects from any tariffs on our business and operations in future periods will depend on various factors, including the application and rates of such tariffs, as well as the expansion of such tariffs to include certain goods (such as pharmaceutical products), the magnitude of response by other countries to U.S. tariffs and the length of time such tariffs are in effect. For additional discussion of these and other risks, see Part II, Item 1A. Risk Factors, of this Quarterly Report on Form 10-Q.

Macroeconomic and other challenges

Uncertain macroeconomic conditions, including the risk of inflation, fluctuating interest rates and instability in the financial system, as well as rising healthcare costs, continue to pose challenges to our business. Uncertainty around tariffs and trade protection measures in the United States and other countries, including the imposition of new, retaliatory or sector-specific tariffs, along with ongoing geopolitical conflicts and rising geopolitical tensions, continue to create additional uncertainty in global macroeconomic conditions. Additionally, with public and private healthcare-provider focus, the industry continues to be subject to cost containment measures and significant pricing pressures, resulting in net price declines.

Moreover, provisions of the IRA, as well as the 340B Program, have negatively affected, and are likely to continue to negatively affect, our business. For example, ENBREL and Otezla have been selected by CMS for Medicare price setting beginning in 2026 and 2027, respectively. In addition to the IRA, other recent and proposed U.S. policy actions focus on drug pricing, including the Most-Favored-Nations Prescription Drug Pricing Executive Order (MFN EO) that is aimed at using price benchmarks from other developed countries to set U.S. pricing targets, and the July MFN Letter that was delivered to many pharmaceutical companies, including Amgen, and called for drug manufacturers to: 1) extend MFN pricing to Medicaid; 2) guarantee MFN pricing to Medicaid, Medicare and commercial payers on all newly launched drugs; 3) use future increased revenues from outside the United States to reduce U.S. drug prices; and 4) participate in direct-to-consumer models to provide MFN pricing for certain drugs. The details of these drug pricing actions and how they might be operationalized are unclear, but if put into place they could reasonably be expected to adversely affect our business. See Part II, Item 1A. Risk Factors —Changing U.S. federal coverage and reimbursement policies and practices have affected, and are likely to continue to affect, access to, pricing of, and sales of our products, of this Quarterly Report on Form 10-Q for further discussion.

Finally, wholesale and end-user buying patterns can affect our product sales. These buying patterns can cause fluctuations in quarterly product sales, but have generally not been significant to date when comparing full-year product performance to the prior year. For additional discussion of these and other risks, see Part II, Item 1A. Risk Factors, of this Quarterly Report on Form 10-Q.

Significant developments

The following is a summary of select significant developments affecting our business that occurred since the filing of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025. For additional developments, see our Annual Report on Form 10-K for the year ended December 31, 2024 and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025.

Products/pipeline

Repatha

In August 2025, we announced that the FDA broadened the approved use of Repatha to include adults at increased risk for major adverse cardiovascular events (MACE) due to uncontrolled low-density lipoprotein cholesterol (LDL-C). The update removes a prior requirement for a patient to have been diagnosed with cardiovascular (CV) disease.

In the following discussion of changes in product sales, any reference to unit demand growth or decline refers to changes in purchases of our products by healthcare providers (such as physicians or their clinics), dialysis centers, hospitals and pharmacies. In addition, any reference to increases or decreases in inventory refers to changes in inventory held by wholesaler customers and end users (such as pharmacies) as may be noted.

Total product sales increased 12% and 11% for the three and nine months ended September 30, 2025, respectively, driven by volume growth of 14% for both periods, partially offset by declines in net selling price of 4% and 3%, respectively.

For the three months ended September 30, 2025, U.S. volume grew 13% and ROW volume grew 16%, driven by volume growth in certain brands, including PAVBLU, Repatha, EVENITY, IMDELLTRA/IMDYLLTRA, TEZSPIRE and BLINCYTO.

For the nine months ended September 30, 2025, U.S. and ROW volumes grew 14% each, driven by volume growth in certain brands, including Repatha, PAVBLU, EVENITY, TEZSPIRE, IMDELLTRA/IMDYLLTRA and BLINCYTO.

For the remainder of 2025, we expect volume growth from certain brands to be partially offset by net selling price declines.

Other revenues increased 19% and 7% for the three and nine months ended September 30, 2025, respectively, primarily driven by higher royalty income.

Operating expenses increased 9% and 6% for the three and nine months ended September 30, 2025, respectively, driven by investments in Later-Stage Clinical Programs and Otezla intangible asset impairment charges, partially offset by lower amortization expense from the fair value step-up of inventory acquired from Horizon. See Note 8, Goodwill and other intangible assets, to the condensed consolidated financial statements, for additional information related to the Otezla intangible asset impairment charges.

Uncertain macroeconomic conditions, including uncertainty around tariffs and trade protection measures, ongoing geopolitical conflicts and rising geopolitical tensions, changes in the healthcare ecosystem, and potential government policy actions, including MFN pricing or similar drug pricing reforms, have the potential to introduce variability into product sales. Furthermore, product sales continue to be impacted by actions from governments and other entities to address macroeconomic challenges, provisions of the IRA, inappropriate expanded utilization of the 340B Program and growth in numbers of Medicaid enrollees and uninsured individuals. See Part I, Item 1. Business—Reimbursement, and Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2024; and Part II, Item 1A. Risk Factors, of our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025 and September 30, 2025.

Cost of sales

Cost of sales decreased to 32.2% and 33.7% of total revenues for the three and nine months ended September 30, 2025, respectively, 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 and development

The increase in R&D expense for the three months ended September 30, 2025, was driven by investments in Later-Stage Clinical Programs, including those related to MariTide.

The increase in R&D expense for the nine months ended September 30, 2025, was driven by investments in Later-Stage Clinical Programs, including those related to MariTide, partially offset by lower spend in Marketed Product Support and Research and Early Pipeline.

We expect to continue to grow our spend on Later-Stage Clinical Programs as we advance our pipeline.

Selling, general and administrative

The increase in SG&A expense for the three months ended September 30, 2025, was driven by higher general and administrative expenses, partially offset by lower Horizon acquisition-related expenses.

The decrease in SG&A expense for the nine months ended September 30, 2025, was primarily driven by lower commercial product-related expenses and lower Horizon acquisition-related expenses, partially offset by higher general and administrative expenses.

Other

Other operating expenses for the three and nine months ended September 30, 2025, included Otezla intangible asset impairment charges of $400 million and $1.2 billion, respectively. See Note 8, Goodwill and other intangible assets, to the condensed consolidated financial statements.

Other operating expenses for the three and nine months ended September 30, 2024, included impairment charges associated with IPR&D assets and changes in the fair values of contingent consideration liabilities, both related to our Teneobio, Inc. acquisition from 2021.

Nonoperating expenses/income and income taxes

Nonoperating expenses/income and income taxes were as follows (dollar amounts in millions):


	Three months ended September 30,						Nine months ended September 30,
	2025			2024			2025			2024
Interest expense, net	$	(685)		$	(776)		$	(2,102)		$	(2,408)
Other income, net	$	2,080		$	1,830		$	3,204		$	1,288
Provision for income taxes	$	705		$	271		$	1,084		$	364
Effective tax rate	18.0		%	8.7		%	14.5		%	9.5		%

Interest expense, net

Interest expense, net, decreased for the three and nine months ended September 30, 2025, primarily due to lower average debt outstanding.

Other income, net

Other income, net, increased for the three and nine months ended September 30, 2025, primarily due to higher net unrealized gains on equity investments, primarily BeOne. See Note 6, Investments, to the condensed consolidated financial statements.

Income taxes

As previously reported, the OECD reached an agreement to align countries on a minimum corporate tax rate and an expansion of the taxing rights of market countries. Effective January 1, 2024, select individual countries, including the United Kingdom and EU member countries, have enacted the global minimum tax agreement. Additional countries, including Singapore, enacted the minimum tax agreement, effective January 1, 2025. Singapore’s enactment of the agreement applies irrespective of the Company’s incentive grant. Due to the currently enacted scope of the agreement, the Company and its subsidiaries are now subject to a 15% minimum tax rate on adjusted financial statement income. In June 2025, the United States and the other six countries that make up the G7 nations jointly announced that U.S. companies would be exempted from certain minimum taxes related to the OECD agreement. However, significant details regarding the G7 announcement remain uncertain and individual countries that have enacted the OECD agreement, including countries not within the G7, must amend their local legislation for the G7 announcement to become effective. The continued response of other countries, including the U.S. territory of Puerto Rico to the OECD agreement and the G7 announcement remains highly uncertain. The continued enactment of the OECD agreement, either by all OECD participants or unilaterally by individual countries, could result in tax increases or double taxation in the United States or foreign jurisdictions.

On July 4, 2025, OB3 was enacted in the United States. OB3 has various provisions, including the permanent extension of certain expiring provisions of the 2017 Tax Act and modifications to the international tax framework. The legislation has multiple effective dates, with certain provisions effective in 2026 and beyond. The impact of these changes on our deferred tax assets and liabilities was recorded in the third quarter of 2025 and did not have a material effect on our effective tax rate or on our condensed consolidated financial statements.

In 2017, we received an RAR and a modified RAR from the IRS for the years 2010–2012, proposing significant adjustments that primarily relate to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico. We disagreed with the proposed adjustments and calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2021, we filed a petition in the U.S. Tax Court to contest two duplicate Statutory Notices of Deficiency (Notices) for the years 2010–2012 that we received in May and July 2021, which seek to increase our U.S. taxable income for the years 2010–2012 by an amount that would result in additional federal tax of approximately $3.6 billion, plus interest. Any additional tax that could be imposed for the years 2010–2012 would be reduced by up to approximately $900 million of repatriation tax previously accrued and paid on our foreign earnings.

In 2020, we received an RAR and a modified RAR from the IRS for the years 2013–2015, also proposing significant adjustments that primarily relate to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico similar to those proposed for the years 2010–2012. We disagreed with the proposed adjustments and calculations and pursued resolution with the IRS appeals office but were unable to reach resolution. In July 2022, we filed a petition in the U.S. Tax Court to contest a Notice for the years 2013–2015 that we previously reported receiving in April 2022 that seeks to increase our U.S. taxable income for the years 2013–2015 by an amount that would result in additional federal tax of approximately $5.1 billion, plus interest. In addition, the Notice asserts penalties of approximately $2.0 billion. Any additional tax that could be imposed for the years 2013–2015 would be reduced by up to approximately $2.2 billion of repatriation tax previously accrued and paid on our foreign earnings.

We are currently under examination by the IRS for the years 2016–2018 with respect to issues similar to those for the 2010 through 2015 period. We expect that the IRS will begin its audit of 2019–2022 in 2025 or early 2026, and we believe that it may seek to continue to audit similar issues related to the allocation of income between the United States and our foreign jurisdictions. In addition, we are under examination by a number of state and foreign tax jurisdictions.

See our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, Part II, Item 1A. Risk Factors— We could be subject to additional tax liabilities, including from an adverse outcome in our ongoing tax dispute with the IRS and other tax examinations, enactment of the OECD minimum corporate tax rate agreement and the adoption and interpretation of new tax legislation including the OBBBA. Such tax liabilities could adversely affect our profitability and results of operations, and Note 4, Income taxes, to the condensed consolidated financial statements of this Quarterly Report on Form 10-Q for further discussion.

Financial condition, liquidity and capital resources

Selected financial data were as follows (in millions):


	September 30, 2025		December 31, 2024
Cash and cash equivalents	$	9,445	$	11,973
Total assets	$	90,141	$	91,839
Current portion of long-term debt	$	2,153	$	3,550
Long-term debt	$	52,434	$	56,549
Stockholders’ equity	$	9,619	$	5,877

Cash and cash equivalents

Our balance of cash and cash equivalents was $9.4 billion as of September 30, 2025. The primary objective of our investment portfolio is to maintain safety of principal, prudent levels of liquidity and acceptable levels of risk. Our investment policy limits interest-bearing security investments to certain types of debt and money market instruments issued by institutions with primarily investment-grade credit ratings, and it places restrictions on maturities and concentration by asset class and issuer.

Capital allocation

Consistent with the objective to optimize our capital structure, we deploy our accumulated cash balances in a strategic manner and consider a number of alternatives, including investments in innovation both internally and externally (including

investments that expand our portfolio of products in areas of therapeutic interest), capital expenditures, repayment of debt, payment of dividends and stock repurchases.

We intend to continue investing in our business while reducing our debt and returning capital to stockholders through the payment of cash dividends and stock repurchases. This reflects our desire to optimize our cost of capital and our confidence in the future cash flows of our business. The timing and amount of future dividends and stock repurchases will vary based on a number of factors, including future capital requirements for strategic transactions, debt levels and debt service requirements, our credit rating, availability of financing on acceptable terms, changes to applicable tax laws or corporate laws, changes to our business model and periodic determination by our Board of Directors that cash dividends and/or stock repurchases are in the best interests of stockholders and are in compliance with applicable laws and the Company’s agreements. In addition, the timing and amount of stock repurchases may also be affected by our overall level of cash, stock price and blackout periods, during which we are restricted from repurchasing stock. The manner of stock repurchases may include block purchases, tender offers, accelerated share repurchases and market transactions.

In August 2025, March 2025 and December 2024, our Board of Directors declared quarterly cash dividends of $2.38 per share of common stock, which were paid in September 2025, June 2025 and March 2025, respectively, an increase of 6% over the quarterly cash dividends paid each quarter in 2024. In October 2025, our Board of Directors declared a quarterly cash dividend of $2.38 per share of common stock, which will be paid in December 2025.

During the nine months ended September 30, 2025, we did not repurchase shares under our stock repurchase program. As of September 30, 2025, $6.8 billion of authorization remained available under the stock repurchase program.

As a result of stock repurchases and quarterly dividend payments, we have an accumulated deficit as of September 30, 2025 and December 31, 2024. Our accumulated deficit is not anticipated to affect our future ability to operate, repurchase stock, pay dividends or repay our debt given our expected continued profitability and strong financial position.

During the nine months ended September 30, 2025 and 2024, debt repayments totaled $5.0 billion and $3.6 billion, respectively. In addition, we opportunistically repurchase our debt when market conditions are favorable. During the nine months ended September 30, 2025 and 2024, we repurchased aggregate principal amounts of our debt of $1.0 billion and $875 million, respectively, for aggregate costs of $683 million and $659 million, respectively, which resulted in the recognition of gains on extinguishment of debt of $264 million and $215 million, respectively, recorded in Other income, net, in the Condensed Consolidated Statements of Income.

We believe that existing funds, cash generated from operations and existing sources of and access to financing are adequate to satisfy our needs for working capital, capital expenditure and debt service requirements, as well as our plans to reduce debt, pay dividends and repurchase stock, and other business initiatives we plan to strategically pursue, including acquisitions and licensing activities. We anticipate that our liquidity needs can be met through a variety of sources, including cash provided by operating activities, borrowings through commercial paper and/or syndicated credit facilities and access to other domestic and foreign debt markets and equity markets. See Part II, Item 1A. Risk Factors— Global economic conditions may negatively affect us and may magnify certain risks that affect our business, of this Quarterly Report on Form 10-Q.

Certain of our financing arrangements contain nonfinancial covenants. In addition, our revolving credit agreement and term loan credit agreement include a financial covenant that requires us to maintain a specified minimum interest coverage ratio of (i) the sum of consolidated net income, interest expense, provision for income taxes, depreciation expense, amortization expense, unusual or nonrecurring charges and other noncash items (consolidated earnings before interest, taxes, depreciation and amortization) to (ii) Consolidated Interest Expense, each as defined and described in the respective agreements. We were in compliance with all applicable covenants under these arrangements as of September 30, 2025.

Cash flows

Our summarized cash flow activity was as follows (in millions):


	Nine months ended September 30,
	2025		2024
Net cash provided by operating activities	$	8,355	$	6,719
Net cash used in investing activities	$	(1,250)	$	(644)
Net cash used in financing activities	$	(9,633)	$	(8,008)

Operating

Cash provided by operating activities has been and is expected to continue to be our primary recurring source of funds. Cash provided by operating activities during the nine months ended September 30, 2025, increased as compared to the same period in the prior year primarily due to higher net income in the current year period after adjustments for noncash items, the timing of tax payments, including an $800 million tax deposit made in the first quarter of 2024, and the timing of working capital items.

Investing

Cash used in investing activities during the nine months ended September 30, 2025 and 2024, was primarily due to capital expenditures of $1.2 billion and $725 million, respectively, including construction costs for new plants and expansion of manufacturing capacity. We currently estimate full year 2025 investments in capital projects to be in the range of $2.2 billion to $2.3 billion.

Financing

Cash used in financing activities during the nine months ended September 30, 2025, was primarily due to the repayment and extinguishment of debt of $5.0 billion and $683 million, respectively, and the payment of dividends of $3.8 billion. Cash used in financing activities during the nine months ended September 30, 2024, was primarily due to the repayment and extinguishment of debt of $3.6 billion and $659 million, respectively, and the payment of dividends of $3.6 billion. See Note 9, Financing arrangements, and Note 10, Stockholders’ equity, to the condensed consolidated financial statements for further discussion.

Critical accounting policies and estimates

The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the notes to the financial statements. Some of those judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions. A summary of our critical accounting policies and estimates is presented in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes to our critical accounting policies and estimates during the nine months ended September 30, 2025.

Item 3.			QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information about our market risk is disclosed in Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, of our Annual Report on Form 10-K for the year ended December 31, 2024, and is incorporated herein by reference. There were no material changes during the nine months ended September 30, 2025, to the information provided in Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, of our Annual Report on Form 10-K for the year ended December 31, 2024, except as related to our market-price sensitive financial instruments disclosed below.

Market-price-sensitive financial instruments

As of September 30, 2025 and December 31, 2024, we were exposed to price risk on equity securities included in our portfolio of investments, which were acquired primarily for the promotion of business and strategic objectives. These investments include our investments in BeOne and Neumora, as well as other publicly and privately held small-capitalization stocks and limited partnerships that invest in early-stage biotechnology companies. A 20% decrease in the aggregate value of our equity investment portfolio as of September 30, 2025 and December 31, 2024, would result in losses in fair value of approximately $1.5 billion and $950 million, respectively.


Item 4.			CONTROLS AND PROCEDURES

We maintain “disclosure controls and procedures,” as such term is defined under the Securities Exchange Act Rule 13a-15(e) that are designed to ensure that information required to be disclosed in Amgen’s Exchange Act reports gets recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information gets accumulated and communicated to Amgen’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to facilitate timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, Amgen’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, Amgen’s management necessarily was required to apply its judgment in evaluating the cost–benefit relationship of possible controls and procedures. We carried out an evaluation under the supervision and with the participation of our management, including Amgen’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of Amgen’s disclosure controls and procedures. Based on their evaluation and subject to the foregoing, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2025.

Management determined that as of September 30, 2025, no changes in our internal control over financial reporting had occurred during the fiscal quarter then ended that materially affected or are reasonably likely to materially affect our internal control over financial reporting.

PART II — OTHER INFORMATION


Item 1.			LEGAL PROCEEDINGS

See Part I—Note 13, Contingencies and commitments, to the condensed consolidated financial statements included in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025 and September 30, 2025, for discussions that are limited to certain recent developments concerning our legal proceedings. Those discussions should be read in conjunction with Part IV—Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024.


Item 1A.			RISK FACTORS

Below we provide in supplemental form the material changes to our risk factors that occurred during the past quarter. Our risk factors disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the year ended December 31, 2024, provide additional disclosure for these supplemental risks and are incorporated herein by reference.

Our sales depend on coverage and reimbursement from government and commercial third-party payers, and pricing and reimbursement pressures have affected, and are likely to continue to affect, our profitability.

Sales of our products depend on the availability and extent of coverage and reimbursement from third-party payers, including government healthcare programs and private insurance plans. Governments and private payers continue to pursue initiatives to manage drug utilization and contain costs. Further, pressures on healthcare budgets from the economic downturn and inflation continue and are likely to increase, across the markets we serve. Payers are increasingly focused on costs, which has resulted, and is expected to continue to result, in lower reimbursement rates for our products and/or narrower patient populations for which payers will reimburse. Continued intense public scrutiny of the price of drugs and other healthcare costs, together with payer dynamics, have limited, and are likely to continue to limit, our ability to set or adjust the price of our products based on their value, which can have a material adverse effect on our business. In the United States, a number of legislative and regulatory proposals have been introduced and/or signed into law to lower drug prices. These include the IRA law that enables the U.S. government to set prices for certain drugs in Medicare, redesigns Medicare Part D benefits to shift a greater proportion of the costs to manufacturers and health plans, and enables the U.S. government to impose penalties if drug prices are increased at a rate faster than inflation (IRA Inflation Penalties). On July 4, 2025, OB3 was enacted and included several changes to Medicare, Medicaid and Affordable Care Act policies, that when implemented, may adversely affect coverage and reimbursement for our products. On May 12, 2025, the Administration issued the Most-Favored-Nations (MFN) Prescription Drug Pricing Executive Order (MFN EO) aimed at using price benchmarks from other developed countries to set U.S. pricing targets. Subsequently, on July 31, 2025 the Administration sent letters to many pharmaceutical manufacturers, including Amgen (the July MFN Letter) as further described below, outlining steps that such manufacturers could take to advance actions consistent with elements of the MFN EO. Such actions could reasonably be expected to adversely affect our business. Additional proposals focused on drug pricing continue to be debated, and additional executive orders or regulatory initiatives focused on drug pricing and competition are likely to be adopted and implemented in some form. It remains unclear what further policies and/or actions the Administration will advance with respect to the MFN EO, IRA implementation, sector-specific trade policies, other drug pricing proposals, or other healthcare regulations affecting pharmaceuticals. Further, state government activity has been dynamic, including a number of states enacting new laws prohibiting restrictions on 340B Program use and limiting drug reimbursement under state run Medicaid programs. Such state laws could also eventually be adopted at the federal level.

We are unable to predict which or how many policy, regulatory, administrative or legislative changes may ultimately be, or effectively estimate the consequences to our business if, enacted and implemented. However, to the extent that payer actions further decrease or modify the coverage or reimbursement available for our products, require that we pay increased rebates or shift other costs to us, limit or affect our decisions regarding the pricing of or otherwise reduce the use of our products, such actions could have a material adverse effect on our business and results of operations.

—Changing U.S. federal coverage and reimbursement policies and practices have affected, and are likely to continue to affect, access to, pricing of, and sales of our products

A substantial proportion of our U.S. business relies on reimbursement from federal government healthcare programs and commercial insurance plans regulated by federal and state governments. See Part I, Item 1. Business—Reimbursement, of our Annual Report on Form 10-K for the year ended December 31, 2024. Our business has been, and will continue to be, affected by legislative actions changing U.S. federal reimbursement policy. For example, the IRA includes provisions requiring that, beginning in 2026, mandatory price setting be introduced in Medicare for certain drugs paid for under Parts B and D, whereby manufacturers must accept a price established by the government or face penalties on all U.S. sales (starting with 10 drugs in 2026, adding 15 in 2027 and 2028, and adding 20 in 2029 and subsequent years such that, by 2031, approximately 100 drugs could be subject to such set prices). The Medicare price setting process for the first 10 drugs subject to Medicare price setting in Part D began in 2023, which includes ENBREL, our product that currently generates considerable revenues. In 2024, CMS set a price for ENBREL under Medicare Part D that is significantly lower than currently applicable, beginning on January 1, 2026, which we expect will negatively impact its profitability in Medicare. See Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of operations—Product sales—ENBREL. In January 2025, CMS announced the next 15 drugs for Medicare price setting that will be applicable beginning on January 1, 2027, which includes Otezla. In October 2025, CMS set a price, beginning on January 1, 2027, for Otezla under Medicare Part D that is significantly lower than the current price, which we expect will negatively impact its profitability in Medicare. Further, CMS has issued guidance, effective for the 2028 cycle, that allows for the re-setting of prices for drugs for which it previously set a price. Depending on the growth and success of our medicines, other of our medicines may also be subject to selection by CMS in the next, or in a future, cycle of mandatory Medicare price setting, we may be required to accept a price set by the government for Medicare using the process that was applied to ENBREL and Otezla. On April 15, 2025, the Administration issued an executive order (the April 2025 EO) that, among other directives, directs HHS to work with Congress to align the treatment of small molecule drugs and biologics in the Medicare price setting program under the IRA. It is currently unclear how such modifications would affect the timeframe in which Medicare price setting becomes applicable for selected drugs or biologics. Also under the IRA, Medicare Part D was redesigned to cap beneficiary out-of-pocket costs and, beginning January 1, 2025, Federal reinsurance will be reduced in the catastrophic phase (resulting in a shift and increase of such costs to Part D plans and manufacturers, including by requiring manufacturer discounts on applicable drugs). Further, the IRA inflation penalties allow CMS to collect rebates from manufacturers if price increases outpace inflation. Such rebate obligations began to accrue October 1, 2022 for Medicare Part D and January 1, 2023 for Medicare Part B. Several of our products have also been on lists that are issued and updated on a quarterly basis by CMS under a related program under which Medicare beneficiaries are charged reduced coinsurance if price increases exceed inflation. The IRA’s Medicare price setting and Medicare redesign are likely to have a material adverse effect on our sales, our business and our results of operations, and such impact is expected to increase through the end of the decade and will depend on factors including the extent of our portfolio’s exposure to Medicare reimbursement, the rate of inflation over time, the number of our products selected for Medicare price setting and the timing of market entry of generic or biosimilar competition. Further, following the enactment of the IRA, the environment remains dynamic, and U.S. policymakers continue to demonstrate interest in health care and drug pricing changes as well as potential changes affecting intellectual property. For example, in April 2024, CMS finalized policy changes that will give Part D plans more flexibility to substitute biosimilars for innovator products on formularies in 2025. Implementation of OB3 also may impact access to and reimbursement of our products. For example, the Congressional Budget Office has projected significant cuts to federal Medicaid spending over the next decade and an increase in the number of people without health insurance. This would place greater stress on state budgets and hospital finances, and could result in reduced access to medicines, additional pressure to further discount medicines and growth of 340B Program utilization. The April 2025 EO also directs HHS to provide recommendations within 180 days to accelerate the approval of generics, biosimilars, combination products and second-in-class medications, as well as to address Medicaid drug rebates and Medicaid drug payment methodologies, and, within one year, to develop and implement a plan to test a payment model to enable Medicare to obtain pharmaceuticals at lower cost. The MFN EO directs HHS to set MFN price targets, which HHS identified in a press release as the lowest price in an OECD country with a gross domestic product (GDP) per capita of at least 60% of the U.S. GDP per capita and applicable to brand products that do not currently have generic or biosimilar competition. The MFN EO outlined potential actions if significant progress towards MFN price targets is not made including: proposing a rulemaking plan to impose MFN pricing; considering actions to support importation of drugs in certain circumstances; undertaking enforcement action against anti-competitive practices; considering actions regarding the export of drugs or precursor material; and reviewing and potentially modifying or revoking approvals granted for drugs that are newly determined to be unsafe, ineffective or improperly marketed. The MFN EO also directs the Secretary of Commerce and the U.S. Trade Representative to take all necessary and appropriate action to ensure foreign countries are not engaged in any act, policy or practice that may be unreasonable or discriminatory, and directs HHS to facilitate direct-to-consumer purchasing programs at MFN prices. The July MFN Letter calls for drug manufacturers to: 1) extend MFN pricing to Medicaid; 2) guarantee MFN pricing to Medicaid, Medicare and commercial payers on all newly launched drugs; 3) use future increased revenues from outside the U.S. to lower U.S. drug prices; and 4) participate in direct-to-consumer models to provide MFN pricing for certain drugs. The details of these requests and how they might be

operationalized are unclear, but if put into place they could reasonably be expected to adversely affect our business. Recently, three drug manufacturers announced agreements with the Administration that are reported to fully address the July MFN Letter, and other manufacturers may enter into similar agreements in the future. Separate from the MFN EO and the July MFN Letter, other CMS policy changes and demonstration projects to test new care, delivery and payment models can also significantly affect how drugs, including our products, are covered and reimbursed.

We also face risks related to the reporting of pricing data that affects reimbursement of and discounts provided for our products. U.S. government price reporting regulations are complex and may require biopharmaceutical manufacturers to update certain previously submitted data. If our submitted pricing data are incorrect, we may become subject to substantial fines and penalties or other government enforcement actions, which could have a material adverse effect on our business and results of operations. In addition, as a result of restating previously reported price data, we may be required to pay additional rebates and provide additional discounts.

—Changing reimbursement and pricing actions in various states have negatively affected, and may continue to negatively affect, access to, and have affected, and may continue to affect, sales of our products

At the state level, legislation, government actions and ballot initiatives can also affect how our products are covered and reimbursed and/or create additional pressure on our pricing decisions. Existing and proposed state pricing laws, which may move forward more rapidly than similar efforts at the federal level, have added complexity to the pricing of drugs. A number of states have adopted, and many other states are considering, PDABs, drug importation programs, reference pricing schemes and other drug pricing actions, including proposals designed to require biopharmaceutical manufacturers to report to the state proprietary pricing information or provide advance notice of certain price increases.

States are also enacting laws referencing the IRA and seeking to regulate and prohibit restrictions on the 340B Program. For example, following the passage of the IRA, bills have been proposed in multiple states that would apply the drug price caps set by HHS for Medicare to drug prices in an individual state, and such references to IRA price caps have also been included in PDAB legislation. For Medicaid patients, states have established a Medicaid drug spending cap (New York) and implemented a new review and supplemental rebate negotiation process (Massachusetts). Eight states (Colorado, Maine, New Hampshire, New Jersey, Maryland, Minnesota, Oregon and Washington) have enacted laws that establish PDABs to identify drugs that pose affordability challenges, and four such states include authority for the state PDABs to set upper payment limits on certain drugs for in-state patients, payers and providers. In 2024 and 2025, no fewer than 17 states and nine states, respectively, introduced PDAB legislation, and in 2025 Maryland expanded the scope of its PDAB law to include the commercial market. The eight states with enacted PDAB laws are in various phases of implementation, with Colorado’s PDAB being the furthest along. The Colorado PDAB deemed three of five drugs “unaffordable,” including ENBREL, and in October 2025 the Colorado PDAB established an Upper Payment Limit (UPL) substantially lower than the wholesale acquisition cost of ENBREL that would be generally applicable to all formulations of ENBREL, effective no earlier than January 1, 2027, and will be reviewed annually. On July 16, 2025, Washington state’s PDAB selected ENBREL for one of its first affordability reviews. Following the timeline and process established by the state for such affordability review, the manufacturer and the PDAB will undertake a number of required interactions. However, the Washington state PDAB may not establish a UPL for any prescription drug before January 1, 2027. Further, inappropriate expanded utilization of the 340B Program from broadened application of the 340B discounts has had, and is expected to continue to have, a negative impact on the Company’s product sales, business and results of operations. Twenty states (Louisiana, Arkansas, West Virginia, Minnesota, Mississippi, Missouri, Maryland, North Dakota, South Dakota, Utah, Nebraska, New Mexico, Colorado, Tennessee, Oregon, Vermont, Hawaii, Oklahoma, Rhode Island and Maine) have enacted laws with mandates on manufacturers participating in the 340B Program, and, in 2025, no fewer than 30 states have introduced similar legislation. These bills vary, but typically include provisions restricting a manufacturer’s ability to direct drugs in 340B channels, recognizing 340B contract pharmacies and a prohibition on requiring the inclusion of 340B claims modifiers. With OB3’s reductions to federal Medicaid funding to states, increased pressure is anticipated for providers to find and preserve existing revenue sources at the state level, which may result in increased use of 340B contract pharmacy mandates. In Genesis Health Care, Inc. v. Becerra , the U.S. District Court for the District of South Carolina issued an order in November 2023 enjoining the Health Resources and Services Administration from enforcing a more restrictive interpretation against Genesis Health Care as to who qualifies as a patient under the 340B Program, potentially expanding access to 340B discounts for healthcare systems. Since this decision, several courts have rejected arguments that state 340B laws are preempted by the federal 340B statute and have declined to enjoin such laws. These rulings, including decisions in Arkansas, Mississippi, Louisiana, Maryland, Minnesota and Tennessee, have been accompanied by a growing number of states pursuing similar legislation.

Additionally, in 2024, the FDA authorized Florida to move forward with its importation program proposal, though the state has not yet completed any significant steps towards importation within the two-year authorization window. Colorado, Maine, New Hampshire, New Mexico, Texas and Vermont have also enacted state importation laws, and some have submitted plans for approval to the FDA. Other states could adopt similar approaches or could pursue different policy changes in a continuing effort to reduce their costs. Further, the April 2025 EO also directs HHS to, within 90 days, streamline and improve the drug importation program to ease the process for states to obtain drug importation approvals. On May 21, 2025, the FDA issued a press release indicating it was taking steps to enhance state importation programs and would offer individual states and tribes the opportunity to submit draft proposals for pre-review and to meet with the agency to obtain initial feedback prior to formally submitting importation proposals. While under federal law biologics remain exempt from such state importation activities, our small molecule products could be impacted by these initiatives.

Ultimately, as with U.S. federal government actions, existing or future state government actions or ballot initiatives may also have a material adverse effect on our product sales, business and results of operations.

—U.S. commercial payer actions have affected, and may continue to affect, access to and sales of our products

Payers, including healthcare insurers, PBMs, integrated healthcare delivery systems (vertically-integrated organizations built from consolidations of healthcare insurers and PBMs) and group purchasing organizations, are continuing to seek ways to further reduce their costs. With increasing frequency, payers are adopting benefit plan changes that shift a greater proportion of drug costs to patients. Such measures include more limited benefit plan designs, high deductible plans, higher patient co-pay or coinsurance obligations and more significant limitations on patients’ use of manufacturer commercial co-pay assistance programs. Further, government regulation of payers may affect these trends. Payers, including PBMs, have sought, and continue to seek, price discounts or rebates in connection with the placement of our products on their formularies or those they manage, and to also impose restrictions on access to, or usage of, our products (such as Step Therapy), require that patients receive the payer’s prior authorization before covering the product, and/or chosen to exclude certain indications for which our products are approved. For example, some payers require physicians to demonstrate or document that the patients for whom Repatha has been prescribed meet their utilization criteria, and these requirements have served to limit patient access to Repatha treatment. In an effort to reduce barriers to access, we reduced the net price of Repatha by providing greater discounts and rebates to payers (including PBMs that administer Medicare Part D prescription drug plans), and in response to a very high percentage of Medicare patients abandoning their Repatha prescriptions rather than paying their co-pay, we introduced a set of new National Drug Codes to make Repatha available at a lower list price. However, affordability of patient out-of-pocket co-pay cost has limited, and, going forward, may in the future limit, patient use. Further, despite these net and list price reductions, some payers have restricted, and may continue to restrict, patient access and may seek further discounts or rebates or take other actions, such as changing formulary coverage for Repatha, that could reduce its sales. These factors have limited, and may continue to limit, patient affordability and use, negatively affecting Repatha sales.

Further, significant consolidation in the health insurance industry has resulted in a few large insurers and PBMs, which places greater pressure on pricing and usage negotiations with biopharmaceutical manufacturers, significantly increasing discount and rebate requirements and limiting patient access and usage. See our Annual Report on Form 10-K for the year ended December 31, 2024, Part I, Item 1A. Risk Factors —Concentration of sales at certain of our wholesaler distributors, and consolidation of private payers, such as insurers, and PBMs has negatively affected, and may continue to negatively affect, our business. This high degree of consolidation among insurers, PBMs and other payers, including integrated healthcare delivery systems and/or with specialty or mail-order pharmacies and pharmacy retailers, has increased the negotiating leverage such entities have over us and other biopharmaceutical manufacturers and has resulted in greater price discounts, rebates and service fees realized by those payers from our business. Each of CVS, Express Scripts and United Health Group (among the top six integrated health plans and PBMs) have Rebate Management Organizations that further increase their leverage to negotiate deeper discounts on their behalf and for the benefit of their other customers. Ultimately, additional discounts, rebates, fees, coverage changes, plan changes, restrictions or exclusions imposed by these commercial payers could have a material adverse effect on our product sales, business and results of operations. Policy reforms advanced by Congress, the Administration or the states that refine the role of PBMs in the U.S. marketplace could have downstream implications or consequences for our business and how we interact with these entities. For example, in September 2024, the Federal Trade Commission brought action against the three largest PBMs alleging anticompetitive and unfair rebating practices. In addition, multiple Congressional Committees have been investigating PBM practices and have also proposed legislation that could increase transparency and reporting of these practices and/or impact rebates and service fees. The results of such inquiries could have an effect on manufacturer interactions with PBMs, resulting in changes to access for certain medicines. See our Annual Report on Form 10-K for the year ended December 31, 2024, Part I, Item 1A. Risk Factors —Concentration of sales at certain of our wholesaler distributors, and consolidation of private payers, such as insurers, and PBMs has negatively affected, and may continue to negatively affect, our business.

Our business is also affected by policies implemented by private healthcare entities that process Medicare claims, including Medicare Administrative Contractors. For example, in 2022, several Medicare Administrative Contractors issued notice that TEZSPIRE would be added to their “self-administered drug” exclusion lists. Although the Medicare Administrative Contractors subsequently removed TEZSPIRE from their exclusion lists, these exclusions, if reintroduced and/or implemented, would result in Medicare beneficiaries with severe asthma losing access to TEZSPIRE coverage under Medicare Part B and potentially also under Medicare Advantage.

—Government and commercial payer actions outside the United States have affected and will continue to affect access to and sales of our products

Outside the United States, we expect countries will also continue to take actions to reduce their drug expenditures and to reduce intellectual property protections. See Part I, Item 1. Business—Reimbursement, of our Annual Report on Form 10-K for the year ended December 31, 2024. Pressures to decrease drug expenditures may intensify as governments take actions to address budgets strained by high inflation and weak economic conditions, including in Europe where the effects of the Russia–Ukraine conflict have challenged the economies in that region. Further, the EU is currently undergoing a review and revision of its general pharmaceutical legislation that, while full implementation is not expected before 2027, has led to proposals that would reduce intellectual property protection for new products (including potentially shortening the duration of regulatory data exclusivity and orphan drug exclusivity protections), as well as change the reimbursement and regulatory landscape. International reference pricing has been widely used by many countries outside the United States to control costs. International reference pricing policies can change quickly and frequently and may not reflect differences in the burden of disease, indications, market structures or affordability across countries or regions. Other expenditure control practices, including the use of revenue clawbacks, rebates and caps on product sales, are also used in various foreign jurisdictions. In addition, countries may refuse to reimburse, or may restrict the reimbursed population for a product, when their national health technology assessments do not consider a medicine to demonstrate sufficient clinical benefit beyond existing therapies or to meet certain cost effectiveness thresholds. For example, despite the European Medicines Agency’s approval of Repatha for the treatment of patients with established atherosclerotic disease, prior to 2020, the reimbursement of Repatha in France was limited to a narrower patient population (such as those with homozygous familial hypercholesterolemia (HoFH)) following a national health technology assessment. Many countries decide on reimbursement between potentially competing products through national or regional tenders that often result in one product receiving most, or all of, the sales in that country or region. Failure to obtain coverage and reimbursement for our products, a deterioration in their existing coverage and reimbursement, or a decline in the timeliness or certainty of payment by payers to hospitals and other providers, has negatively affected, and may further negatively affect, the ability or willingness of healthcare providers to prescribe our products for their patients and otherwise negatively affect the use of our products or the prices we realize for them. Such failures and changes have had, and could in the future have, a material adverse effect on our product sales, business and results of operations.

Global economic conditions may negatively affect us and may magnify certain risks that affect our business.

Our operations and performance have been, and may continue to be, affected by global economic conditions. The economic downturn resulting from the COVID-19 pandemic precipitated a global recession, which was followed by high rates of inflation and actions taken by financial regulators to raise interest rates. Instability in the financial system, tighter lending standards and higher interest rates have added stress that may create additional vulnerabilities in the global economy, the effects of which may be of an extended duration. Additionally, with higher interest rates, deficits (including those associated with the pandemic), and other fiscal pressures, governments may be unable to sustain their previously high levels of fiscal spending. Further, in the United States, Congress was not able to come to agreement on extending government funding before a September 30, 2025 deadline, resulting in a federal government shutdown, and government funding remains at risk of additional disruptions if legislation providing full funding for the fiscal year is not enacted. In addition, as this budget impasse reportedly involves disagreement over the continuation of Affordable Care Act premium subsidies, this disagreement could lead to pressure on Congress to take further actions to pay for healthcare. Also, the federal government shutdown has disrupted, and may have the potential to disrupt, certain federal agency operations, government contract negotiations and regulatory activities, including delays to the U.S. Customs and Border Protection’s processing of import clearances for products and materials, and potential delays to the FDA’s review of product applications and new indication filings. Further, these and other financial pressures have caused, and may continue to cause, government or other third-party payers to more aggressively seek cost containment measures in healthcare and other settings. See Our sales depend on coverage and reimbursement from government and commercial third-party payers, and pricing and reimbursement pressures have affected, and are likely to continue to affect, our profitability . As a result of global economic conditions, some third-party payers may delay or be unable to satisfy their reimbursement obligations. Job losses or other economic hardships (including inflation) may also affect patients’ ability to afford healthcare as a result of increased co-pay or deductible obligations, greater cost sensitivity to existing co-pay or deductible obligations, lost healthcare insurance coverage or for other reasons. We believe such conditions have led and could continue to lead to reduced demand for our products, which could have a material adverse effect on our product sales, business and results of operations. The cumulative effects of inflationary pressures, an uncertain trade environment with escalating and

rapidly-changing tariffs, and the effects from the armed conflict in Ukraine (including the effects of the sanctions that were implemented in response to the conflict and the resulting impacts on the commodity market and supply chains) and the Middle East have also increased our operating expenses and may continue to affect our operating expenses. Our operational costs, including the cost of energy, materials, labor, distribution and our other operational and facilities costs are subject to market conditions and are being adversely affected by inflationary pressures. Inflationary pressure has increased, potentially due, in part, to newly imposed tariffs and retaliatory trade actions. Although we monitor our distributors’, customers’ and suppliers’ financial condition and their liquidity to mitigate our business risks, some of our distributors, customers and suppliers may become insolvent, which could have a material adverse effect on our product sales, business and results of operations. A significant worsening of global economic conditions could precipitate or materially amplify the other risks described herein. On April 2, 2025, the Administration issued an executive order (the April 2025 Tariff EO) imposing a universal 10% tariff on all imported goods, with certain exceptions including pharmaceuticals. The April 2025 Tariff EO imposed additional higher tariffs on approximately 60 countries with which the United States has trade deficits. However, on April 9, 2025 the Administration temporarily placed the country-specific tariffs on hold for 90 days, except the tariff on goods imported from China, which was subsequently raised to 145%. Shortly after the April 2025 Tariff EO, China announced 34% retaliatory tariffs that were subsequently increased to 125% on goods imported from the United States. The EU also announced 25% retaliatory tariffs on certain goods imported from the United States, excluding pharmaceuticals, which was subsequently paused for 90 days in response to the Administration’s pause on country-specific tariffs. While the April 2025 Tariff EO exempts pharmaceuticals, the universal 10% tariff and any foreign retaliatory tariffs will increase certain of our costs, including the materials we use to manufacture our products as well as to conduct our research and development activities, such as delivery devices, consumable supplies and certain other laboratory materials, and the tariffs imposed by China may negatively affect our business in that country. In July 2025, the Administration signed executive orders that raised or modified the country-specific tariffs for more than 60 countries that became effective on August 7, 2025 (the July Tariff EOs). On August 21, 2025, the Administration also announced that it reached an agreement with the EU on a trade framework that establishes a baseline 15% tariff on most EU goods, with a specific exemption for generic pharmaceuticals, beginning on September 1, 2025. In April 2025, the Administration also initiated an investigation under Section 232 of the Trade Expansion Act of 1962 of the importation of pharmaceuticals, pharmaceutical ingredients and their derivative products, which may lead to the imposition of a sector-specific tariff on such products. In July 2025, the Administration stated the intention that such tariff rate could be up to 200% and could be effective in 12 to 18 months following such tariff’s finalization. Further details about such potential tariff on pharmaceuticals remain uncertain. Depending on the scope of any final Section 232 tariff on the pharmaceuticals, it could apply not only to finished pharmaceutical products but also to active pharmaceutical ingredients (APIs), and key starting and upstream materials, potentially increasing our manufacturing and development costs. As such, a Section 232 tariff on pharmaceuticals could significantly increase our costs, particularly for our products that rely on globally distributed manufacturing, transportation or sourcing networks. On September 25, 2025, it was reported that the Administration would impose a 100% tariff on all branded or patented pharmaceutical products unless the manufacturer is in the process of building a manufacturing plant in the United States. Details regarding the scope, timing and implementation of this proposal remain uncertain. Subsequently, the Administration indicated these pharmaceutical tariffs were “paused” while they negotiate with companies on MFN pricing. Additionally, if the current tariff exemptions applicable to pharmaceutical products are revoked, our product sales and research and development activities may also be adversely affected. Further, the administrative requirements of tariffs across global trade could also slow and/or delay the processing and delivery of products and materials in supply chains. On October 24, 2025, the Administration initiated, under the Trade Act of 1974, a Section 301 investigation of China’s implementation of the Economic and Trade Agreement between the U.S. and Chinese governments. This investigation, and any other 301 investigations initiated, may result in additional tariffs on imported goods from China and any other foreign markets subsequently investigated, respectively, potentially including pharmaceutical products and other goods that Amgen requires for the manufacture of our products. If subject to Section 301 tariffs, China, and other affected foreign governments, may retaliate against such tariffs by imposing tariffs of their own on U.S.-made goods. Given the many uncertainties and variables, it is currently unclear the extent, and degree, to which existing and future tariffs will disrupt and adversely affect our business activities (including product sales, and conduct of clinical trial and research and development activities), and the global economic environment, and/or amplify the other risks described herein. See our Annual Report on Form 10-K for the year ended December 31, 2024, Part I, Item 1A. Risk Factors —We may not be able to access the capital and credit markets on terms that are favorable to us, or at all .

We maintain a significant portfolio of investments on our consolidated balance sheets. In the recent past, the global COVID-19 pandemic and interest rate increases have led to disruption and volatility in the global capital markets. We have certain assets, including equity investments, that are exposed to market fluctuations that could, in a sustained or recurrent series of market disruptions, result in impairments. The value of our investments may also be adversely affected by interest rate fluctuations, inflation, downgrades in credit ratings, illiquidity in the capital markets, geopolitical events and other factors that may result in other-than-temporary declines in the value of our investments. Any of those events could cause us to record impairment charges with respect to our investment portfolio or to realize losses on sales of investments. We also maintain a majority of our cash and cash equivalents in accounts with major multi-national financial institutions, and our deposits at these

institutions exceed insured limits. Market conditions can adversely affect the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a timely manner or at all. Inability to access, or a delay in accessing these funds, could adversely affect our business and financial position.
