September 30, 2024
(未经审计)

1. 显著会计政策摘要
业务
安进公司(包括其合并子公司,简称为“安进”,“本公司”,“我们”,“我们的”或“我们”)是一个全球生物技术先驱,致力于发现,开发,生产和提供创新的人类治疗药物。我们在 一份 业务领域:人类治疗药物。
做法的基础
截至2024年和2023年9月30日的三个月和九个月的临时未经审计财务信息,已经根据公认会计原则(GAAP)编制,并包含安进认为为了公正呈现其在所有重大方面的合并经营业绩而必要的所有调整(仅包括正常、经常性调整,除非另有说明)。临时结果并不一定反映整个财年的结果。
需结合截至2023年12月31日的10-K年报中包含的合并基本报表及相关附注,以及截至2024年3月31日和2024年6月30日的10-Q季度报告中包含的浓缩合并基本报表及相关附注,阅读浓缩合并基本报表。
合并原则
综合简明的基本报表包括了安进及其绝大部分拥有的子公司的账户。在确定我们是否为可变利益实体的主要受益方时,我们考虑我们是否具有指导最重要地影响实体经济绩效的活动的权力,以及是否具有承担实体损失或有权从实体获得可能对该实体重要的利益的义务。我们不在任何变量利益实体中具有重要利益 我们是主要受益方的变量利益实体,所有重要公司间交易和余额在合并时已予以消除。为符合当前的呈现,基本报表和附注中对以前时期进行了某些重新分类。
估计的使用
符合GAAP的合并基本报表的准备要求管理层作出估计和假设,这些估计和假设影响合并基本报表及其附注中报告的金额。实际结果可能与这些估计存在差异。
物业、厂房和设备,净值
固定资产按历史成本净额记录,扣除累计折旧和摊销,金额为$10.3亿和美元9.8 亿美元,分别截至2024年9月30日和2023年12月31日。
最近的会计准则解释。
2023年12月,财务会计准则委员会(FASB)发布了《财务会计准则更新(ASU)第2023-09号,所得税(主题740):改进所得税披露》,以改进所得税披露要求,要求提供有关几项所得税披露的更详细信息,例如增强所交所得税的披露,并要求对有效所得税率和调整项进行细分披露。该准则适用于2024年12月15日后开始的公开业务实体年度。允许提前采用,实体可以以前瞻性方式或选择追溯性应用该准则。我们目前正在评估采纳这一新准则对我们相关披露的影响。
在2023年11月,FASB 发布了 ASU 第2023-07号,关于细分报告(主题 280):改善可报告细分的披露,以通过对重要的细分费用和其他临时细分报告披露的增强披露来改善可报告细分的披露要求,包括针对只有一个可报告细分的公司。该标准适用于在2023年12月15日后开始的年度期间和在2024年12月15日后开始的临时期间的公共业务实体。允许提前采用,并且该标准要求对所有以前的期进行追溯适用。
7


陈述的期间。我们预计采纳这一新标准将导致对我们的基本报表附注的递增披露。

2. 收购
Horizon Therapeutics plc的收购
2023年10月6日,安进通过收购所有未结清的价值为$的地平线全部股份完成了对地平线的收购。116.50 每股现金,代表约$的总考虑。27.8地平线是一家专注于发现、开发和商业化针对罕见、自身免疫和严重炎症性疾病患者关键需求的药物的全球生物技术公司。这项被视为业务合并完成的收购,符合安进传递创新药物、为患有严重疾病的患者带来重大变革的核心战略,并通过增加首创的早期生命周期药物,包括治疗甲状腺眼病的TEPEZZA、治疗慢性难治性痛风的KRYSTEXXA和治疗神经脊髓膜视神经炎光谱障碍的UPLIZNA,增强了安进领先的罕见病产品组合。地平线被完全收购后成为安进的全资子公司,并其业务在收购日期起被纳入我们的合并基本报表中。
截至2024年9月30日的九个月期间,收购的购买价格分配已完成,计量期调整也已最终确定,这包括了购买价格分配的变化,导致商誉的净增加约为$25百万。这些计量期的调整主要是由于对收购资产和负债的调整,包括递延税项属性,这些调整是基于收购日期存在的事实和情况,而不是由收购日期后的事件导致的。如果这些调整在收购日期时已被执行,则这些调整不会对安进在截至2024年9月30日的九个月期间的运营结果产生重大影响,也不会对之前的期间结果产生重大影响。
下表总结了获得资产和承担负债的最终总对价及分配的收购日期公允价值,包括计量期调整(单位:百万):
现金及现金等价物$681 
存货5,014 
物业、厂房和设备,净值318

已取得的总资产,减去负债
$27,833 
从2023年12月31日至2024年3月31日,净合同资产增加$27.8本次交易的总对价为(i)现金对价转移给普通股东的$26.7 十亿;(ii)现金对价转移给已归属和未归属的期权、未归属的限制性股票单位(RSU)奖励和未归属的绩效股票单位(PSU)奖励的$523 百万;(iii)安进替代奖励的公允价值(基于未归属员工RSU奖励的转换)为$180 百万,代表非现金对价;(iv)安进在收购交割日结算的一部分Horizon债务,金额为$382 百万。安进发行了 1.7 百万的替代股权奖励,原归属条件不变,其公允价值基于收购日期的公允价值和转换计算进行确定。
估计的公允价值为$20.7开发产品科技权利和知识产权研发无形资产的估计价值为数十亿美元,采用多期超额收益收入法确定,该方法通过应用折现率将预期未来现金流折现为现值,折现率代表市场参与者在评估这些无形资产时使用的估计率。预计的现金流基于对各自无形资产的某些假设,包括对未来收入和支出的估计、完成开发所需的时间和资源,以及获得FDA及其他监管机构的市场审批的概率。开发产品科技权利将在约 10 年内按收直线法摊销,从收购日期起使用直线方法。
8


收购存货的估计公允价值为$5.0十分之一亿美元的存货公允价值是通过比较销售法来确定的,该方法使用存货的实际或预期销售价格作为基数,并对销售努力以及买方努力的利润进行调整。 存货公允价值调整正在通过一个加权平均存货周转率摊销,我们估计这个周转率大约为 27 个月,从收购日期开始。
一个递延税务负债为$2.5十亿被确认于与所收购可识别资产和承担负债的账面基础和税基的临时差异,主要由收购的无形资产驱动,以及一项相关的递延税务资产,用于预期外税抵免,金额为$795百万。
收购日期考虑金额超过分配给所收购的资产和假定负债的公允价值的$3.1十亿美元被记录为商誉,无法用于税务扣除。商誉的价值代表了从收购的产品中预期的协同效应和其他收益。
附加补充的形势财务信息
下表展示了截至2023年9月30日的假设合并的未审计补充交替结果, 安进和Horizon实体的三个月和九个月的结果,仿佛Horizon的收购发生在2022年1月1日(以百万为单位):
2023年9月30日结束的三个月截至2023年9月30日的九个月中,
总收入
$7,854 $22,728 
净利润$902 $3,518 
未经审计的补充形式合并财务信息是使用收购会计法准备的,并基于安进和Horizon的历史财务信息。为了反映2022年1月1日收购的发生,未经审计的补充形式财务信息包括以下调整: (i) 根据可识别无形资产和存货增值的公允价值计算的增量摊销费用; (ii) 与发行债务融资收购相关的额外利息费用; (iii) 使用估计的有效税率对合并实体的所得税影响。未经审计的补充形式财务信息并不一定表明如果在2022年1月1日完成收购,简明合并运营结果会是什么样。此外,未经审计的补充形式财务信息也不是对合并公司未来运营结果的预测,也不反映与收购相关的任何协同效应或成本节约的预期实现。

4. Income taxes
The effective tax rates for the three and nine months ended September 30, 2024, were 8.7% and 9.5%, respectively, compared with 11.1% and 15.0%, respectively, for the corresponding periods in the prior year.
The decrease in our effective tax rate for the three months ended September 30, 2024, was primarily due to the earnings mix as a result of the inclusion of the Horizon business (including the amortization of Horizon acquired assets), partially offset by the quarter-to-date unrealized gains on our strategic equity investments (primarily BeiGene). See Note 6, Investments—BeiGene, Ltd. The decrease in our effective tax rate for the nine months ended September 30, 2024, was primarily due to the earnings mix as a result of the inclusion of the Horizon business (including the amortization of Horizon acquired 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 where 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 a tax incentive grant through 2050. Additionally, the Company’s operations conducted in Singapore are subject to a tax incentive grant through 2036. Our foreign earnings are also subject to U.S. tax at a reduced rate of 10.5%. Additionally, effective January 1, 2024, selected individual countries, including the United Kingdom and EU member countries, have enacted the global minimum tax agreement. Our legal entities in such countries, along with their direct and indirect subsidiaries, are now subject to a 15% minimum tax rate on adjusted financial statement income.
Beginning on January 1, 2023, we were no longer subject to a 4% excise tax in the U.S. territory of Puerto Rico on the gross intercompany purchase price of goods and services from our manufacturer in Puerto Rico. We qualify for and are subject to the alternative income tax rate on industrial development income of our Puerto Rico affiliate. In the United States, this income tax qualifies for foreign tax credits. Both this income tax and the associated foreign tax credits are generally recognized in our provision for income taxes. We accounted for the 2022 excise tax that was capitalized in Inventories as an expense in Cost of sales when the related products were sold in the first half of 2023, and a foreign tax credit was not recognized with respect to the excise tax expense in 2023. We do not have this excise tax exposure in 2024.
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 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 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 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 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 is currently scheduled to begin on November 4, 2024.
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. 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, 2024, the gross amounts of our UTBs increased by $40 million and $120 million, respectively, as a result of tax positions taken during the current year. Substantially all of the UTBs as of September 30, 2024, if recognized, would affect 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

For the three and nine months ended September 30, 2024 and 2023, the number of antidilutive employee stock-based awards excluded from the computation of diluted EPS was not significant.

Cash and cash equivalents in the above table excludes bank account cash of $435 million and $540 million as of September 30, 2024 and December 31, 2023, respectively.
All interest-bearing securities as of September 30, 2024 and December 31, 2023, mature in one year or less.
For the three and nine months ended September 30, 2024 and 2023, realized gains and losses on interest-bearing securities were not material. Realized gains and losses on interest-bearing securities are 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
BeiGene, Ltd.
Our ownership interest in BeiGene was approximately 18% as of both September 30, 2024 and December 31, 2023, and the fair values of our investment were $4.3 billion and $3.4 billion, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. In the first quarter of 2023, we began to account for our ownership interest as an equity security with a readily determinable fair value, with changes in fair value recorded in Other income, net, in our Condensed Consolidated Statements of Income. See Note 11, Fair value measurement. During the three months ended September 30, 2024 and 2023, we recognized unrealized gains of $1.6 billion and $30 million, respectively, recorded in Other income, net, in our Condensed Consolidated Statements of Income. During the nine months ended September 30, 2024 and 2023, we recognized unrealized gains of $836 million and $1.2 billion, respectively, recorded in Other income, net, in our Condensed Consolidated Statements of Income.

Subject to certain exceptions or otherwise agreed to by BeiGene, while Amgen holds at least 5.0% of BeiGene’s outstanding common stock, (A) we may only sell our BeiGene 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 BeiGene’s outstanding common stock in any rolling 12-month period.
Other equity securities
Excluding our equity investments in BeiGene (discussed above) and Neumora (discussed below), we held investments in other equity securities with readily determinable fair values (publicly traded securities) of $336 million and $494 million as of September 30, 2024 and December 31, 2023, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three and nine months ended September 30, 2024 and 2023, net unrealized gains and losses 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, 2024 and 2023, were not material.
We held investments of $318 million and $309 million in equity securities without readily determinable fair values as of September 30, 2024 and December 31, 2023, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. During the three and nine months ended September 30, 2024 and 2023, 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, 2024 and 2023, were not material.
Equity method investments
Neumora Therapeutics, Inc.
As of September 30, 2024 and December 31, 2023, our ownership interests in Neumora were approximately 22.1% and 23.2%, respectively, and the fair values of our investment were $467 million and $603 million, respectively, which are 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 our 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, 2024 and 2023, we recognized unrealized gains of $119 million and $153 million, respectively, and during the nine months ended September 30, 2024 and 2023, we recognized $136 million of unrealized losses and $134 million of unrealized gains, 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 $272 million and $251 million as of September 30, 2024 and December 31, 2023, respectively, which are included in Other noncurrent assets in the Condensed Consolidated Balance Sheets. These investments, 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, 2024, unfunded additional commitments to be made for these investments during the next several years amounted to $139 million. For the three and nine months ended September 30, 2024 and 2023, net unrealized gains and losses from our limited partnership investments were not material.

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. Marketing-related rights primarily consists of rights related to the sale and distribution of marketed products. R&D technology rights pertain to technologies used in R&D that have alternative future uses.
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 three months ended September 30, 2024 and 2023, we recognized amortization associated with our finite-lived intangible assets of $1.2 billion and $693 million, respectively. During the nine months ended September 30, 2024 and 2023, we recognized amortization associated with our finite-lived intangible assets of $3.6 billion and $2.1 billion, respectively. Amortization of intangible assets is primarily included in Cost of sales in the Condensed Consolidated Statements of Income. As of September 30, 2024, the total estimated amortization of our finite-lived intangible assets for the remaining three months ending December 31, 2024, and the years ending December 31, 2025, 2026, 2027, 2028 and 2029, are $1.2 billion, $4.5 billion, $3.9 billion, $3.9 billion, $2.9 billion and $2.2 billion, respectively.

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

Interest-bearing and equity securities
The fair values of our money market mutual funds and equity investments in publicly traded securities, including our equity investments in BeiGene and Neumora, as of September 30, 2024 and December 31, 2023, 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.
Contingent consideration obligations
As a result of our business acquisitions, we have incurred contingent consideration obligations as discussed below. The contingent consideration obligations are recorded at their fair values by using probability-adjusted discounted cash flows, and we revalue these obligations each reporting period until the related contingencies have been resolved. The fair value measurements of these obligations are based on significant unobservable inputs related to licensing rights and product candidates acquired in business combinations, and they are reviewed quarterly by management in our R&D and commercial sales organizations. The inputs include, as applicable, estimated probabilities and the timing of achieving specified development, regulatory and commercial milestones as well as estimated annual sales. Significant changes that increase or decrease the probabilities of achieving the related development, regulatory and commercial events or that shorten or lengthen the time required to achieve such events or that increase or decrease estimated annual sales would result in corresponding increases or decreases in the fair values of the obligations, as applicable. Changes in the fair values of contingent consideration obligations are recognized in Other operating expenses in the Condensed Consolidated Statements of Income.

As of September 30, 2024 and December 31, 2023, our contingent consideration obligations are primarily the result of our acquisition of Teneobio, Inc. in October 2021, which obligates us to pay the former shareholders payments upon achieving separate development and regulatory milestones with regard to various R&D programs.
Summary of the fair values of other financial instruments
Cash equivalents
The fair values of cash equivalents are approximated at their carrying values due to the short-term nature of such financial instruments.
Borrowings
We estimate the fair values of our fixed-rate notes by using Level 2 inputs. As of September 30, 2024 and December 31, 2023, the aggregate fair values of our fixed-rate notes were $58.0 billion and $59.2 billion, respectively, and the carrying values of this debt were $58.6 billion and $60.6 billion, respectively. The estimate of the fair values of our Term loans is approximated as the carrying values as of September 30, 2024 and December 31, 2023 as these debt instruments bear interest at floating rates.
During the nine months ended September 30, 2024 and 2023, there were no transfers of assets or liabilities between fair value measurement levels, and there were no material remeasurements to 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, 2024 and December 31, 2023, we had outstanding foreign currency forward contracts with aggregate notional amounts of $7.1 billion and $6.6 billion, respectively. We have designated these foreign currency forward contracts, which are primarily euro based, as cash flow hedges. Accordingly, we report 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 reported 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, 2024, were as follows (notional amounts in millions):
Foreign currencyU.S. dollars
Hedged notesNotional amountsInterest ratesNotional amountsInterest rates
2.00% 2026 euro Notes

£475 5.5 %$747 6.0 %
4.00% 2029 pound sterling Notes
£700 4.0 %$1,111 4.6 %
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, 2024, and amounts expected to be recognized during the subsequent 12 months are not material.

Fair value hedges
To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that qualified for and were designated as fair value hedges. These interest rate swap contracts effectively convert fixed-rate coupons to floating-rate coupons over the terms of the related hedge contracts. As of both September 30, 2024 and December 31, 2023, we had interest rate swap contracts with aggregate notional amounts of $6.7 billion, that hedge certain portions of our long-term debt issuances. During the nine months ended September 30, 2024, interest rate swaps with an aggregate notional amount of $1.4 billion matured in connection with the repayment of the 3.625% 2024 Notes. In addition, we entered into new interest rate swaps with respect to the 5.25% 2033 Notes for an aggregate notional amount of $1.4 billion at an interest rate of SOFR plus 1.8%.
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):

No portions of our cash flow hedge contracts were excluded from the assessment of hedge effectiveness. As of September 30, 2024, amounts expected to be recognized into earnings during the subsequent 12 months on our foreign currency and cross-currency swap contracts are 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, 2024 and December 31, 2023, the total notional amounts of these foreign currency forward contracts were $82 million and $457 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, 2024 and 2023.

Our derivative contracts that were in liability positions as of September 30, 2024, 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 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) provided by 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, 2023, 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; 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, 2023; and in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024 and June 30, 2024.
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 Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023; and in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024 and June 30, 2024, 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 Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023; and in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024 and June 30, 2024, 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.
Repatha Patent Litigation
Patent Disputes in the International Region
Germany
On October 17, 2024 in Sanofi-Aventis Deutschland GmbH (Sanofi-Aventis) and Regeneron Pharmaceuticals, Inc.’s (Regeneron) actions seeking damages arising from the provisional enforcement of an injunction against PRALUENT®, the Munich Regional Court scheduled a hearing for February 26, 2025.

Japan
On September 16, 2024, Amgen filed an appeal brief with the Japanese Intellectual Property High Court, seeking to overturn the Japanese Patent Office’s decision to reject Amgen’s amended patent claims following a remand of the case to the Japanese Patent Office from the Japanese Intellectual Property High Court.
Prolia/XGEVA Biologics Price Competition and Innovation Act (BPCIA) Litigation
Amgen Inc. et al. v. Samsung Bioepis Co. Ltd., et al.
On August 12, 2024, Amgen Inc. and Amgen Manufacturing Limited LLC filed a lawsuit in the U.S. District Court for the District of New Jersey (New Jersey District Court) against Samsung Bioepis Co. Ltd. (Bioepis) and Samsung Biologics Co., Ltd., (Biologics, and collectively with Bioepis, Samsung) based on the submission to the FDA of a Biologics License Application (BLA) seeking approval to market and sell a biosimilar version of Amgen’s Prolia and XGEVA products. The complaint asserts infringement of the following 34 patents: U.S. Patent Nos. 7,364,736; 7,888,101; 7,928,205; 8,058,418; 8,247,210; 8,460,896; 8,680,248; 9,012,178; 9,320,816; 9,328,134; 9,359,435; 9,481,901; 10,106,829; 10,167,492; 10,227,627; 10,421,987; 10,513,723; 10,583,397; 10,655,156; 10,822,630; 10,894,972; 10,907,186; 11,098,079; 11,130,980; 11,254,963; 11,292,829; 11,299,760; 11,384,378; 11,427,848; 11,434,514; 11,634,476; 11,685,772; 11,744,950; and 11,946,085 (collectively, the Asserted Patents). Amgen seeks a judgment from the New Jersey District Court that Samsung has infringed or will infringe one or more claims of each of the Asserted Patents and, based on that judgment, a permanent injunction prohibiting the commercial manufacture, use, offer to sell, or sale within the United States or importation into the United States of Samsung’s proposed denosumab biosimilar before expiration of each of the Asserted Patents found infringed. Amgen also seeks monetary remedies for any past acts of infringement. Bioepis filed its Answer and Counterclaims in response to the Complaint on October 1, 2024. Biologic’s response to the Complaint is due on October 28, 2024.
Amgen Inc. et al. v. Fresenius Kabi USA, LLC et al.
On October 4, 2024, Amgen Inc. and Amgen Manufacturing Limited LLC filed a lawsuit in the U.S. District Court for the Northern District of Illinois (Northern Illinois District Court) against Fresenius Kabi USA, LLC, Fresenius SwissBiosim GmbH, Fresenius Kabi Deutschland, GmbH, and Fresenius Kabi Austria GmbH (collectively, Fresenius) based on the submission to the FDA of a BLA seeking approval to market and sell a biosimilar version of Amgen’s Prolia and XGEVA products. The complaint asserts infringement of the following 33 patents: U.S. Patent Nos. 7,364,736; 7,888,101; 7,928,205; 8,053,236; 8,058,418; 8,460,896; 8,680,248; 9,012,178; 9,228,168; 9,320,816; 9,328,134; 9,359,435; 10,106,829; 10,167,492; 10,227,627; 10,513,723; 10,583,397; 10,655,156; 10,822,630; 10,894,972; 11,077,404; 11,098,079; 11,130,980; 11,254,963; 11,299,760; 11,319,568; 11,434,514; 11,459,595; 11,744,950; 11,786,866; 11,946,085; 11,952,605; and 12,084,686 (collectively, the Asserted Patents). Amgen seeks a judgment from the Northern Illinois District Court that Fresenius has infringed or will infringe one or more claims of each of the Asserted Patents and, based on that judgment, a permanent injunction prohibiting the commercial manufacture, use, offer to sell, or sale within the United States or importation into the United States of Fresenius’s proposed denosumab biosimilar before expiration of each of the Asserted Patents found infringed. Amgen also seeks monetary remedies for any past acts of infringement.
PAVBLU (formerly ABP 938 (aflibercept-ayyh)) Patent Litigation
On September 23, 2024, the U.S. District Court for the Northern District of West Virginia denied Regeneron’s motion for a preliminary injunction, and Regeneron filed a notice of appeal, a motion to expedite the appeal, and an emergency motion for an injunction pending resolution of the appeal and for an administrative stay with the U.S. Court of Appeals for the Federal Circuit (the Federal Circuit Court).

The plaintiffs allege that, in 2004, Amgen entered into an anticompetitive agreement with certain F. Hoffman-La Roche AG entities (Roche) and other parties that provided Amgen with rights to Roche’s patents in a manner that enabled Amgen to allegedly unlawfully extend the life of patents applicable to ENBREL and, thereby, delay biosimilar entry. Amgen’s response to the complaint is due on November 4, 2024.

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. Amgen focuses on areas of high unmet medical need and leverages its 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, ENBREL, XGEVA, Repatha, Otezla, TEPEZZA, EVENITY, KYPROLIS, Nplate, Aranesp, KRYSTEXXA, BLINCYTO, Vectibix and TEZSPIRE. We also market a number of other products, including but not limited to MVASI, AMJEVITA/AMGEVITA, Neulasta, RAVICTI, Parsabiv, UPLIZNA, LUMAKRAS/LUMYKRAS, Aimovig, TAVNEOS, PROCYSBI, EPOGEN and IMDELLTRA.
Macroeconomic and other challenges
Uncertain macroeconomic conditions, including the risk of inflation, higher interest rates and instability in the financial system, as well as rising healthcare costs continue to pose challenges to our business. Further, ongoing geopolitical conflicts 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 Drug Pricing Program, have affected, and are likely to continue to affect, our business. 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. See Part II, Item 1A. Risk Factors, of this Quarterly Report on Form 10-Q.

Significant developments
Following is a summary of selected significant developments affecting our business that occurred since the filing of our Quarterly Report on Form 10-Q for the period ended June 30, 2024. For additional developments, see our Annual Report on Form 10-K for the year ended December 31, 2023, and our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024 and June 30, 2024.
Products/Pipeline
TEPEZZA
In September 2024, we announced TEPEZZA was approved for the treatment of active or high clinical activity score (CAS) thyroid eye disease (TED) in Japan.
UPLIZNA
In September 2024, we announced top-line results of the Phase 3 MINT trial of UPLIZNA, an anti-CD19 humanized monoclonal antibody. MINT is a Phase 3, randomized, placebo-controlled, double-blind trial assessing the efficacy and safety of UPLIZNA in patients with generalized myasthenia gravis (gMG). The trial met its primary endpoint, with a statistically significant change from baseline in Myasthenia Gravis Activities of Daily Living (MG-ADL) score for UPLIZNA compared with placebo at week 26 of the combined patient population. UPLIZNA demonstrated a statistically significant and clinically meaningful change from baseline compared to placebo for four out of five key secondary endpoints. The overall safety results during the placebo-controlled period of the trial were consistent with the known safety profile of UPLIZNA.
Rocatinlimab
In September 2024, we announced top-line results of the Phase 3 ROCKET HORIZON trial of rocatinlimab, an investigational therapy targeting the OX40 receptor. ROCKET HORIZON is a Phase 3, randomized, placebo-controlled, double-blind trial assessing the efficacy, safety and tolerability of rocatinlimab monotherapy in adults with moderate to severe atopic dermatitis. The study met its co-primary endpoints and reached statistically significant difference from placebo for all key secondary endpoints. Overall safety findings in the study were comparable to those seen in the Phase 2b study.

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 24% and 22% for the three and nine months ended September 30, 2024, respectively, primarily driven by volume growth of 29% and 27%, respectively, partially offset by declines in net selling price of 2% and 3%, respectively.
31


For the three months ended September 30, 2024, U.S. volume grew 34% and ROW volume grew 18%. Product sales from acquired Horizon products contributed $1.1 billion, with volume growth of 12% from our other brands, including Repatha, TEZSPIRE, EVENITY, BLINCYTO and Prolia.
For the nine months ended September 30, 2024, U.S. volume grew 31% and ROW volume grew 17%. Product sales from acquired Horizon products contributed $3.1 billion, with volume growth of 10% from our other brands, including Repatha, TEZSPIRE, EVENITY, Prolia and BLINCYTO.
For the remainder of 2024, we expect product sales growth from acquired Horizon products and volume growth from our other brands to be partially offset by net selling price declines on a year-over-year basis at a portfolio level.
Uncertain macroeconomic conditions, changes in the healthcare ecosystem and geopolitical conflicts have the potential to introduce variability into product sales. Furthermore, product sales continue to be impacted by actions from governments and other entities to curb high inflation, provisions of the IRA, the 340B Drug Pricing Program and growth in numbers of Medicaid enrollees and uninsured individuals. See Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2023, and Part II, Item 1A. Risk Factors, of our Quarterly Reports on Form 10-Q for the periods ended March 31, 2024, June 30, 2024 and September 30, 2024.
Other revenues remained relatively unchanged for the three months ended September 30, 2024. Other revenues increased for the nine months ended September 30, 2024, driven by higher royalty income and corporate partner revenue from licensed products.
Operating expenses increased for the three and nine months ended September 30, 2024, primarily driven by higher amortization expense from Horizon acquisition-related assets and expenses from the acquired Horizon business.

Cost of sales
Cost of sales increased to 38.9% and 40.0% of total revenues for the three and nine months ended September 30, 2024, respectively, driven by higher amortization expense from Horizon acquisition-related assets and, to a lesser extent, higher royalty and profit share expense. The increase for the nine months ended September 30, 2024 was partially offset by the prior year impact of the 2022 Puerto Rico tax law change, which replaced an excise tax with an income tax beginning in 2023. See Note 4, Income taxes, to the condensed consolidated financial statements.
Research and development
The increase in R&D expense for the three and nine months ended September 30, 2024, was driven by higher spend in later-stage clinical programs, marketed product support and research and early pipeline, including Horizon-acquired programs. 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, 2024, was primarily driven by commercial expenses related to Horizon-acquired products.
The increase in SG&A expense for the nine months ended September 30, 2024, was driven by expenses from the acquired Horizon business and other commercial expenses.
Other
Other operating expenses for the three and nine months ended September 30, 2024, consisted primarily of 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.
Other operating expenses for the three and nine months ended September 30, 2023, consisted of a net impairment charge resulting from the termination of AMG 340 and expenses related to our restructuring plan initiated in the first quarter of 2023.

Effective tax rate8.7 %11.1 %9.5 %15.0 %
Interest expense, net
Interest expense, net, remained relatively unchanged for the three months ended September 30, 2024. The increase in Interest expense, net, for the nine months ended September 30, 2024, was primarily due to higher average debt outstanding and higher weighted-average fixed and floating interest rates on the debt.
Other income, net
The increase in Other income, net, for the three months ended September 30, 2024, was primarily due to higher unrealized gains on our strategic equity investments, primarily BeiGene, partially offset by reduced interest income as a result of lower average cash balances.
The decrease in Other income, net, for the nine months ended September 30, 2024, was primarily due to lower current year net unrealized gains on our strategic equity investments, primarily BeiGene, and reduced interest income as a result of lower average cash balances. Prior period net gains on our strategic equity investments were principally composed of amounts recognized on our BeiGene investment in the first quarter of 2023 as a result of a change from the equity method of accounting to recording this investment at fair value with changes in fair value recognized in earnings. See Note 6, Investments, to the condensed consolidated financial statements.

Income taxes
The decrease in our effective tax rate for the three months ended September 30, 2024, was primarily due to the earnings mix as a result of the inclusion of the Horizon business (including the amortization of Horizon acquired assets), partially offset by the quarter-to-date unrealized gains on our strategic equity investments (primarily BeiGene). See Note 6, Investments—BeiGene, Ltd., to the condensed consolidated financial statements. The decrease in our effective tax rate for the nine months ended September 30, 2024, was primarily due to the earnings mix as a result of the inclusion of the Horizon business (including the amortization of Horizon acquired assets).
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, selected individual countries, including the United Kingdom and EU member countries, have enacted the global minimum tax agreement. Our legal entities in the countries that have enacted the agreement, along with their direct and indirect subsidiaries, are now subject to a 15% minimum tax rate on adjusted financial statement income. Other countries, including the United States and the U.S. territory of Puerto Rico, have not yet enacted the OECD agreement, and implementation remains highly uncertain. The continued enactment of the 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.
As of January 1, 2023, we are no longer subject to a 4% excise tax in the U.S. territory of Puerto Rico on the gross intercompany purchase price of goods and services from our manufacturer in Puerto Rico. We qualify for and are subject to the alternative income tax rate on industrial development income of our Puerto Rico affiliate. In the United States, this income tax qualifies for foreign tax credits under the U.S. Treasury final foreign tax credit regulations. See Note 4, Income taxes, to the 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 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 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 is currently scheduled to begin on November 4, 2024.
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. 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.
See our Annual Report on Form 10-K for the year ended December 31, 2023, Part I, 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, and we anticipate additional tax liabilities from certain provisions of the 2017 Tax Act that will go into effect in 2026; such tax liabilities could adversely affect our profitability and results of operations, and Note 4, Income taxes, to the condensed consolidated financial statements in this filing for further discussion.

Financial condition, liquidity and capital resources
Selected financial data were as follows (in millions):
September 30, 2024December 31, 2023
Cash and cash equivalents$9,011 $10,944 
Total assets$90,883 $97,154 
Current portion of long-term debt$3,544 $1,443 
Long-term debt$56,854 $63,170 
Stockholders’ equity$7,527 $6,232 
Cash and cash equivalents
Our balance of cash and cash equivalents was $9.0 billion as of September 30, 2024. 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.
42


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 2024, March 2024 and December 2023, our Board of Directors declared quarterly cash dividends of $2.25 per share of common stock, which were paid in September 2024, June 2024 and March 2024, respectively, and was an increase of 6% over the quarterly cash dividends paid each quarter in 2023. In October 2024, our Board of Directors declared a quarterly cash dividend of $2.25 per share of common stock that will be paid in December 2024.
During the nine months ended September 30, 2024, we did not repurchase any of our common stock under our stock repurchase program. As of September 30, 2024, $7.0 billion of authorization remained available under our stock repurchase program.
As a result of stock repurchases and quarterly dividend payments, we have an accumulated deficit as of September 30, 2024 and December 31, 2023. Our accumulated deficit is not anticipated to affect our future ability to operate, repurchase stock, pay dividends or repay our debt given our strong financial position.
During the nine months ended September 30, 2024 and 2023, debt repayments totaled $3.6 billion and $1.5 billion, respectively. In addition, we opportunistically repurchase our debt when market conditions are favorable. During the nine months ended September 30, 2024 and 2023, we paid $659 million and $550 million, respectively, to extinguish principal amounts of debt of $875 million and $739 million, respectively.
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, sales of marketable securities, borrowings through commercial paper and/or syndicated credit facilities and access to other domestic and foreign debt markets and equity markets. See our Annual Report on Form 10-K for the year ended December 31, 2023, Part I, Item 1A. Risk Factors—Global economic conditions may negatively affect us and may magnify certain risks that affect our business.
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, 2024.

Cash flows
Our summarized cash flow activity was as follows (in millions):
 Nine months ended
September 30,
 20242023
Net cash provided by operating activities$6,719 $7,933 
Net cash (used in) provided by investing activities$(644)$885 
Net cash (used in) provided by financing activities$(8,008)$18,294 
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, 2024, decreased compared with the prior year period due to the timing of repatriation and income tax payments to the IRS, partially offset by higher net income after adjustments for noncash items and timing of working capital.
Investing
Cash used in investing activities during the nine months ended September 30, 2024, was primarily due to capital expenditures of $725 million, including construction costs of new plants in North Carolina and Ohio. Cash provided by investing activities during the nine months ended September 30, 2023, was primarily due to net cash inflows from sales and maturities of marketable securities of $1.7 billion, partially offset by capital expenditures of $863 million, including construction costs of new plants in North Carolina and Ohio. We currently estimate full year 2024 spending on capital projects to be approximately $1.3 billion.
Financing
Cash used in financing activities during the nine months ended September 30, 2024, was primarily due to the payment of dividends of $3.6 billion and the repayment and extinguishment of debt of $3.6 billion and $659 million, respectively. Cash provided by financing activities during the nine months ended September 30, 2023, was primarily due to proceeds from the issuance of debt of $23.8 billion, partially offset by the payment of dividends of $3.4 billion, as well as the repayment and extinguishment of debt of $1.5 billion and $550 million, respectively. 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, 2023.

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, 2023, and is incorporated herein by reference. There were no material changes during the nine months ended September 30, 2024, 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, 2023.

44


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, 2024.
Management determined that as of September 30, 2024, 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 periods ended March 31, 2024, June 30, 2024 and September 30, 2024, 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, 2023.

Item 1A.RISK FACTORS
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. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. You should carefully consider the risks and uncertainties our business faces. The risks described below are not the only ones we face. Our business is also subject to the risks that affect many other companies, such as employment relations, general economic conditions, geopolitical events and international operations. Further, additional risks not currently known to us or that we currently believe are immaterial may in the future materially and adversely affect our business, operations, liquidity and stock price.
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, 2023, 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 have resulted, and are expected to continue to result, in lower reimbursement rates for our products or narrower 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, particularly over the past few years, a number of legislative and regulatory proposals have been introduced and/or signed into law that attempt 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 portion of the costs to manufacturers and enables the U.S. government to impose penalties if drug prices are increased at a rate faster than inflation (IRA Inflation Penalties). 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. In March 2024, the Administration released its budget plan for fiscal year 2025 that included proposals to expand the IRA’s drug price setting to more drugs and sooner after launch and making IRA Inflation Penalties applicable to commercial health insurance. Government actions or ballot initiatives at the state level also represent a highly active area of policymaking and experimentation, including proposals that limit drug reimbursement under state run Medicaid programs based on decisions of drug affordability boards, use of reference prices, or permitting importation of drugs from Canada. Such state policies may 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 portion 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, 2023. Our business has been and will continue to be affected by legislative actions changing U.S. federal reimbursement policy. For example, in 2022, the IRA was enacted and 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 began in August 2023 when CMS announced the first 10 drugs for Medicare price setting, which includes ENBREL, currently a product that generates considerable revenue. Effective July 30, 2024, CMS set a price for ENBREL in Medicare Part D, applicable beginning on January 1, 2026, which we expect will negatively impact its profitability. See Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of operations—Product sales—ENBREL. 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. If other of our medicines are selected by CMS for mandatory Medicare price setting, we may be required to accept a price set by the government for Medicare similar to the process that was applied to ENBREL. Also under the IRA, starting on January 1, 2024, 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 certain drugs). Further, the IRA created a mechanism for CMS to collect rebates from manufacturers if price increases outpace inflation. Rebate obligations began to accrue October 1, 2022 for Medicare Part D and January 1, 2023 for Medicare Part B, but CMS has not yet issued invoices and has some discretion as to when to issue such invoices to manufacturers. We expect that several of our products will be subject to these inflation rebates, and several of our products have 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 drug pricing controls 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 mandatory price setting and the timing of market entry of generic or biosimilar competition. Further, following the passage of the IRA, the environment remains dynamic and U.S. policymakers continue to demonstrate interest in health care and drug pricing changes. For example, in April 2024, CMS finalized policy changes that will give Part D plans more flexibility to substitute biosimilars for reference products on formularies in 2025. In early 2023, the HHS selected new healthcare payment and delivery models for testing, in response to an October 2022 Executive Order on Lowering Prescription Drug Costs for Americans, including the Accelerating Clinical Evidence Model, which could introduce new payment methods that reduce reimbursement for drugs approved under accelerated approval. That Executive Order followed a 2021 Executive Order designed to increase competition in the healthcare sector, including by calling for the FDA to work with states that seek to develop prescription drug importation programs and the FTC to apply greater scrutiny of anticompetitive activity and responses to which include actions from the HHS (which released a report with drug pricing proposals that seek to promote competition) and from the U.S. Patent and Trademark Office (which has taken steps to strengthen coordination with the FDA to address perceived impediments to generic drug and biosimilar competition). 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. In the fourth quarter of 2021, HHS released a plan to address drug pricing that included potential future mandatory models that link payment for prescription drugs and biologics to certain factors, including the overall cost of care. In March 2024, the Administration released its budget plan for fiscal year 2025 that included proposals to expand the number of drugs subject to mandatory Medicare price setting under the IRA, imposing such price setting activity earlier, and extending to commercial health insurance the requirement that drug manufacturers pay rebates if price increases outpace inflation. While those proposed expansions of the IRA’s drug pricing controls have not been enacted, the proposals demonstrate that this area continues to be a focus of the Administration.
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 have added complexity to the pricing of drugs and may already be affecting industry pricing decisions. A number of states have adopted, and many other states are considering, PDABs, drug importation programs, reference pricing schemes, and other 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 the 340B Drug Pricing 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 PDAB to set upper payment limits on certain drugs for in-state patients, payers and providers. In 2024, no fewer than 17 states introduced PDAB legislation. The eight states with enacted PDAB laws are in various phases of implementation, with Colorado’s PDAB being the furthest along. In August 2023, the Colorado PDAB announced the first five drugs to undergo an affordability review, three of which, including ENBREL, have since been deemed “unaffordable” and will be subject to rulemaking to establish an Upper Payment Limit (UPL). For ENBREL, a UPL could be effective as soon as the third quarter of 2025. Further, Louisiana, Arkansas, West Virginia, Minnesota, Kansas, Mississippi, Missouri and Maryland have enacted laws with mandates on manufacturers participating in the 340B drug pricing program, and, thus far in 2024, no fewer than 25 states have considered similar legislation. These bills vary, but include provisions on 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. In March 2024, the U.S. Court of Appeals for the 8th Circuit ruled that Arkansas’ Act 1103, which prohibits drugmakers from restricting the acquisition or delivery of 340B drugs to covered entities and their contract pharmacies, was not preempted by the federal 340B statute. The decision could increase the number of states that will consider similar legislation. In July 2024, the U.S. District Court for the Southern District of Mississippi denied motions for a preliminary injunction in two cases challenging a similar law in Mississippi, finding that neither plaintiff had demonstrated a substantial likelihood of success on the merits. These orders are being appealed at the U.S. Court of Appeals for the 5th Circuit. In September 2024, the U.S. District Court for the Western District of Louisiana dismissed a lawsuit challenging Louisiana’s 340B contract pharmacy mandate law, and the U.S. District Court for the District of Maryland denied a motion for preliminary injunction challenging a similar law in Maryland. These lawsuits challenging states on their 340B contract pharmacy laws are subsequent to Genesis Health Care, Inc. v. Becerra, where the U.S. District Court for the District of South Carolina issued an order in November 2023 that enjoins the Health Resources and Services Administration from enforcing its more restrictive interpretation of what is considered a patient under the 340B program, to the potential benefit of healthcare systems seeking to expand the application of 340B discounts.
Additionally, on January 5, 2024, the FDA authorized Florida to move forward with its importation program proposal. 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.
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, increasingly seek ways to 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. For example, CMS finalized a policy for plan years starting on or after January 1, 2021 that has caused commercial payers to more widely adopt co-pay accumulator adjustment programs. While the U.S. District Court for the District of Columbia struck down this policy in September 2023 and further clarified in December 2023 that its ruling had the effect of reinstating the co-pay accumulator adjustment policy from 2020, CMS and HHS have signaled that they do not intend to enforce certain restrictions from the 2020 policy that would reduce the adoption of co-pay accumulator adjustment programs, and CMS has indicated that the issue will be addressed in future rulemaking. Payers, including PBMs, have sought, and continue to seek, price discounts or rebates in connection with the
48


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 and may continue 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 may continue to 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 our sales of Repatha. 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. For example, in the United States, as of the beginning of 2024, the top five integrated health plans and PBMs controlled about 92% of all pharmacy prescriptions. 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 five integrated health plans and PBMs) have Rebate Management Organizations that further increase their leverage to negotiate deeper discounts. 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 or the Administration 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 June 2022, the FTC launched an inquiry into the business practices of PBMs and subsequently expanded the investigation to the three rebate management organizations owned by the three largest PBMs, and in September 2024, the FTC brought action against the three largest PBMs alleging anticompetitive and unfair rebating practices. In addition, multiple Congressional Committees are 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, 2023, 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 the second quarter of 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, 2023. Pressures to decrease drug expenditures may intensify as governments take actions to address budgets strained by high inflation, expenditures to respond to the COVID-19 pandemic 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 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 based on an external benchmark of a product’s price in other countries. International reference pricing policies can change quickly and frequently and may not reflect differences in the burden of disease, indications, market structures or affordability differences across countries or regions. Other expenditure control practices, including but not limited to the use of revenue clawbacks, rebates and caps on product sales, are used in various foreign jurisdictions as well. In addition, countries may refuse to reimburse or may restrict the reimbursed population for a product when their national health technology
49


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 EMA’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 changes have had, and could in the future have, a material adverse effect on our product sales, business and results of operations.
A breakdown of our information technology systems, cyberattack or information security breach could significantly compromise the confidentiality, integrity and availability of our information technology systems, network-connected control systems and/or our data, interrupt the operation of our business and/or affect our reputation.
To achieve our business objectives, we rely on sophisticated information technology systems, including hardware, software, technology infrastructure, online sites and networks for both internal and external operations, mobile applications, cloud services and network-connected control systems, some of which are managed, hosted, provided or serviced by third parties. Internal or external events that compromise the confidentiality, integrity and availability of our systems and data may significantly interrupt the operation of our business, result in significant costs and/or adversely affect our reputation.
Our information technology systems are highly integrated into our business, including our R&D efforts, our clinical and commercial manufacturing processes and our product sales and distribution processes. Further, as the majority of our employees work remotely for some portion of their jobs in our hybrid work environment, our reliance on our and third-party information technology systems has increased substantially and is expected to continue to increase. Remote and hybrid working arrangements, including those of many third-party providers, can increase cybersecurity risks due to the challenges associated with managing remote computing assets and security vulnerabilities that are present in many non-corporate and home networks. The complexity and interconnected nature of software, hardware and our systems make them vulnerable to breakdown or other service interruptions, and to software errors or defects, misconfiguration and other security vulnerabilities. For example, in July 2024, businesses worldwide were affected by an information technology outage due to a faulty software update issued by a cybersecurity firm. Although our systems and operations were temporarily affected by the outage, the impact of this firm’s faulty update on the Company was immaterial to our business operations. However, there can be no assurance that a future similar incident would not result in a material adverse effect on our business or results of operations. Upgrades or changes to our systems or the software that we use have resulted and we expect, in the future, will result in the introduction of new cybersecurity vulnerabilities and risks. In 2022, we identified a number of security vulnerabilities introduced into our information systems as a result of flaws that we subsequently identified in software that we had purchased and installed, and these flaws required that we apply emergency patches to certain of our systems. While we did not experience any significant adverse effects as a result of these vulnerabilities, there can be no assurance that we will timely identify and address future vulnerabilities. Our systems are also subject to frequent perimeter network reconnaissance and scanning, phishing and other cyberattacks. For example, as a result of our cybersecurity monitoring of the Horizon legacy information systems, we detected phishing activity in the accounts of two Horizon executives. These accounts were de-activated, the incidents were investigated and the determination was made separately by both our internal cybersecurity team and our external digital forensics and incident response supplier that no confidential information had been exfiltrated. As the cyber-threat landscape evolves, these attacks are growing in frequency, sophistication, and intensity, and are becoming increasingly difficult to detect and increasingly sophisticated in using techniques and tools—including artificial intelligence—that circumvent security controls, evade detection and remove forensic evidence. Such attacks could include the use of harmful and virulent malware, including ransomware or other denials of service, which can be deployed through various means, including the software supply chain, e-mail, malicious websites and/or the use of social engineering/phishing.
50


We have also experienced denial of service attacks against our network, and, although such attacks did not succeed, there can be no assurance that our efforts to guard against the wide and growing variety of potential attack techniques will be successful in the future. Attacks such as those experienced by government entities (including those that approve and/or regulate our products, such as the EMA) and other multi-national companies, including some of our peers, could leave us unable to utilize key business systems or access or protect important data, and could have a material adverse effect on our ability to operate our business, including developing, gaining regulatory approval for, manufacturing, selling and/or distributing our products. For example, in 2017, a pharmaceutical company experienced a cyberattack involving virulent malware that significantly disrupted its operations, including its research and sales operations and the production of some of its medicines and vaccines. As a result of the cyberattack, its orders and sales for certain products were negatively affected. In late 2020, SolarWinds Corporation, a leading provider of software for monitoring and managing information technology infrastructure, disclosed that it had suffered a cybersecurity incident whereby attackers had inserted malicious code into legitimate software updates for its products that were installed by myriad private and government customers, enabling the attackers to access a backdoor to such systems. In 2022, Okta, Inc., a provider of software that helps companies manage user authentication, disclosed that several hundred of its corporate customers were vulnerable to a security breach that allowed attackers to access Okta’s internal network. Although this breach did not have a significant effect on our business, there can be no assurance that a similar future breach would not result in a material adverse effect on our business or results of operations.
Our systems also contain and use a high volume of sensitive data, including intellectual property, trade secrets and other proprietary business information, financial information, regulatory information, strategic plans, sales trends and forecasts, litigation materials and/or personal identifiable information belonging to us, our staff, our patients, customers and/or other parties. In some cases, we utilize third-party service providers to collect, process, store, manage or transmit such data, which have increased our risk. Intentional or inadvertent data privacy or security breaches (including cyberattacks) resulting from attacks or lapses by employees, service providers (including providers of information technology-specific services), business partners, nation states (including groups associated with or supported by foreign intelligence agencies), organized crime organizations, “hacktivists” or others, create risks that our sensitive data may be exposed to unauthorized persons, our competitors or the public. Malicious actors, including those working under state-sponsored campaigns, have sought employment, often in remote information technology roles, as a means to gain inside access at targeted companies. In the third quarter of 2024, an individual used fraudulent identification in connection with their hiring by the Company. While the individual was detected and terminated before any data was extracted or malware installed, there can be no assurance that future attempts by similar actors will be unsuccessful. System vulnerabilities and/or cybersecurity breaches experienced by our third-party service providers have constituted a substantial share of the information security risks that have affected us. For example, in the first half of 2021, a supplier experienced a data breach in which an unauthorized third party acquired access to certain information provided to the supplier in the course of its provision of services to us, including business documents and certain personally identifiable patient information (not including social security or other financial or health insurance information). As required, we promptly notified the applicable state attorneys general and the individuals whose personally identifiable information was affected of this data breach at the supplier. In the third quarter of 2022, another service provider experienced a similar cybersecurity breach in which an attacker exfiltrated certain data (including non-significant Amgen data) from the service provider’s systems. Additionally, in April 2024, one of our former vendors notified us that its subsidiary that had provided us with certain patient support services until mid-2022, experienced a cybersecurity incident that it discovered in February 2024 and that data containing individually identifiable health information of over 1.7 million Amgen patients (that was retained as required by FDA regulations) was involved in the incident. Pursuant to the Health Breach Notification Rule requirements, we notified the FTC of this incident. Although these supplier data breaches have not resulted in material adverse effects on our business, there can be no assurance that a similar future cybersecurity incident would not result in a material adverse effect on our business or results of operations. Further, the timeliness of our awareness of a cybersecurity incident affects our ability to respond to and work to mitigate the severity of such events. For example, in 2020 and 2022, two of our vendors experienced cyberattacks and each initially reported to us that neither event involved our data. However, upon further investigation, they each subsequently informed us that the attackers had accessed limited, non-significant Amgen information. Although neither of these breaches had a significant adverse effect on our business, in the future we may again not receive timely reporting of cybersecurity events and such events could have a material adverse effect on our business.
Cyberattackers are also increasingly exploiting vulnerabilities in commercially available software from shared or open-source code. We rely on third party commercial software that have had and may have such vulnerabilities, but as use of open-source code is frequently not disclosed, our ability to fully assess this risk to our systems is limited. For example, in December 2021, a remote code execution vulnerability was discovered in a software library that is widely used in a variety of commercially available software and services. Although this vulnerability has not resulted in any significant adverse effects on us, there can be no assurances that a similar future vulnerability in the software and services that we use would not result in a material adverse effect on our business or results of operations.
51


Domestic and global government regulators, our business partners, suppliers with whom we do business, companies that provide us or our partners with business services and companies we have acquired or may acquire face similar risks. Security breaches of their systems or service outages have adversely affected systems and could, in the future, affect our systems and security, leave us without access to important systems, products, raw materials, components, services or information, or expose our confidential data or sensitive personal information. For example, in 2019, two vendors that perform testing and analytical services that we use in developing and manufacturing our products experienced cyberattacks, and in April and September of 2020, vendors that provide us with information technology services and clinical data services, respectively, each experienced ransomware attacks. Although there was no breach of our systems, each of these incidents required us to disconnect our systems from those vendors’ systems. While we were able to reconnect our systems following restoration of these vendors’ capabilities without significantly affecting product availability, a more extended service outage affecting these or other vendors, particularly where such vendor is the single source from which we obtain the services, could have a material adverse effect on our business or results of operations. In February 2024, Change Healthcare, a large U.S. insurance claim and co-pay card processing clearinghouse, experienced a ransomware attack that has caused significant disruptions to healthcare provider and pharmacy operations. While Change Healthcare does not directly provide us with services, disruptions to co-pay card support, insurance billing and Medicaid rebate processing led to lost sales and required us to take action to help patients access their medications and to provide extended payment terms to certain customers. Although services have been rerouted and restored, and the impact on our business has been immaterial, similar disruptions may occur in the future stemming from the interconnectedness of the U.S. healthcare ecosystem and industry reliance on centralized claims processing systems and networks, and such future disruptions may have a material adverse effect on our business or results of operations. In addition, we distribute our products in the United States primarily through three pharmaceutical wholesalers, and a security breach that impairs the distribution operations of our wholesalers could significantly impair our ability to deliver our products to healthcare providers and patients. There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls, or procedures, will be fully implemented, complied with or effective in protecting our information technology systems and sensitive data.
Although we have experienced system breakdowns, attacks and information security breaches, we do not believe such breakdowns, attacks and breaches have had a material adverse effect on our business or results of operations. We will continue to experience varying degrees of cyberattacks and other incidents in the future. Even though we continue to invest in the monitoring, protection and resilience of our critical and/or sensitive data and systems, there can be no assurances that our efforts will detect, prevent or fully recover systems or data from all breakdowns, service interruptions, attacks and/or breaches of our systems that could adversely affect our business and operations and/or result in the loss or exposure of critical, proprietary, private, confidential or otherwise sensitive data, which could result in material financial, legal business or reputational harm to us or negatively affect our stock price. While we maintain cyber-liability insurance, our insurance is not sufficient to cover us against all losses that could potentially result from a service interruption, breach of our systems or loss of our critical or sensitive data.
We are also subject to various laws and regulations globally regarding cybersecurity, privacy and data protection, including laws and regulations relating to the collection, storage, handling, use, disclosure, transfer and security of personal data. The legislative and regulatory environment regarding privacy and data protection is continuously evolving and developing and the subject of significant attention globally. For example, we are subject to the EU’s General Data Protection Regulation (GDPR), which became effective in May 2018, and the California Consumer Privacy Act (CCPA), which became effective in January 2020, both of which provide for substantial penalties for noncompliance. The CCPA was amended in late 2020, to create the California Privacy Rights Act to create opt in requirements for the use of sensitive personal data and the formation of a new dedicated agency for the enforcement of the law, the California Privacy Protection Agency. Similar consumer privacy laws went into effect in nine other states, have been enacted (but not yet in effect) in in 11 other states, and have been proposed in six additional states. Outside the United States, other jurisdictions where we operate have passed, or continue to propose, data privacy or cybersecurity legislation and/or regulations. For example, in China, the Personal Information Protection Law and the Data Security Law, which regulate data processing activities associated with personal and nonpersonal data, are in effect and build upon the existing Cybersecurity Law. Further, in March 2024, the European Parliament adopted the Artificial Intelligence Act that provides for EU-wide rules on data quality, transparency, human oversight and accountability with respect to the use of artificial intelligence. In April 2024, the EU also revised its Cybersecurity Directive NIS2 rules that create new cybersecurity risk management and reporting obligations. Failure to comply with these current and future laws could result in significant penalties and reputational harm and could have a material adverse effect on our business and results of operations.
