Risk Factors Dashboard
Once a year, publicly traded companies issue a comprehensive report of their business, called a 10-K. A component mandated in the 10-K is the ‘Risk Factors’ section, where companies disclose any major potential risks that they may face. This dashboard highlights all major changes and additions in new 10K reports, allowing investors to quickly identify new potential risks and opportunities.

TEPEZZA and KRYSTEXXA currently do not face any direct competitors in the United States, Europe or Japan. TEPEZZA faces competition from other therapies, such as corticosteroids, which have been used on an off-label basis to alleviate some of the symptoms of TED. TEPEZZA and KRYSTEXXA may face competition from competitor medicines currently in clinical trials. See TEPEZZA and KRYSTEXXA sections above and Government Regulation—Regulation of Orphan Medicines.
Reimbursement
Sales of our products are dependent on the availability and extent of coverage and reimbursement from third-party payers. In many markets around the world, these payers, including government health systems, private health insurers and other organizations, remain focused on reducing the cost of healthcare; and their efforts have intensified, in part, as a result of uncertain macroeconomic conditions, rising healthcare costs and pressures on healthcare budgets. Drugs remain heavily scrutinized for cost containment. As a result, payers have been and continue to be more restrictive regarding the use of biopharmaceutical products and are scrutinizing the prices of these products while requiring a higher level of clinical evidence to support the benefits such products bring to patients and the broader healthcare system. For example, as discussed below, payers are increasingly using stricter utilization management criteria, such as prior authorization and step therapy, to contain or reduce costs. These pressures become intensified when our products become subject to competition, including from biosimilars.
In the United States, healthcare providers and other entities such as pharmacies and PBMs are reimbursed for covered services and products they deliver through both private-payer and government healthcare programs such as Medicare and Medicaid. We provide negotiated rebates or discounts to healthcare providers, private payers, government payers and PBMs. In addition, we are required to (i) provide rebates or discounts on our products that are reimbursed through certain government programs, including Medicare and Medicaid, and (ii) provide discounts to qualifying healthcare providers under the 340B Program. There has been an increase in the number of entities participating in the 340B Program and in the volume of our medicines dispensed through 340B channels. As a result, this expanded utilization of the 340B Program has had a negative impact on the Company’s financial performance. Further, inappropriate expanded utilization of the 340B Program has had a negative impact on the Company’s financial performance.
Both private and some government payers use formularies to manage access to and utilization of drugs. A drug’s inclusion and favorable positioning on a formulary are essential to ensure patients have full access to a particular drug. Even when access is available, some patients abandon their prescriptions for economic reasons. Payers continue to institute cost reduction and containment measures that lower drug utilization and/or spending altogether and/or shift a greater portion of the costs to patients. Such measures include, but are not limited to, more-limited benefit plan designs, higher patient co-pays or coinsurance obligations, limitations on patients’ use of commercial manufacturer co-pay payment assistance programs (including through co-pay accumulator adjustment or maximization programs), stricter utilization management criteria (such as prior authorization and step therapy) before a patient may get access to a drug, higher-tier formulary placement that increases the level of patient out-of-pocket costs and formulary exclusion, which effectively encourages patients and providers to seek alternative treatments or pay 100% of the cost of a drug. The use of such measures by PBMs and insurers has continued to intensify and has thereby limited Amgen product usage and sales. Furthermore, in the United States, the top six integrated health plans and PBMs controlled about 89% of all pharmacy prescriptions. As a result, PBMs and insurers have greater market power and negotiating leverage to mandate stricter utilization criteria and/or exclude drugs from their formularies in favor of competitor drugs or alternative treatments. In highly competitive treatment markets such as the markets for ENBREL, Otezla, Repatha and
11
Aimovig, PBMs are also able to exert negotiating leverage by requiring incremental rebates from manufacturers in order for them to gain and/or maintain their formulary position.
In addition to market actions taken by private and government payers in the United States, policy makers in both of the major U.S. political parties have supported policies to lower drug costs. See Item 1A. Risk Factors—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. 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 effective January 1, 2026, adding 15 in 2027 and 2028, and adding 20 in 2029 and subsequent years such that by 2031 approximately 100 drugs would be subject to such set prices). CMS has set Medicare Part D prices for ENBREL, effective January 1, 2026, and Otezla, effective January 1, 2027, in each case at significantly lower prices that are expected to negatively impact their profitability in Medicare. See Part IV—Note 13, Goodwill and other intangible assets, to the Consolidated Financial Statements for additional information related to the Otezla intangible asset impairment charges. Also under the IRA, starting on January 1, 2024, Medicare Part D was redesigned to cap beneficiary out-of-pocket costs and reduce Federal reinsurance in the catastrophic phase, increasing cost-sharing obligations for Part D plans and manufacturers, including by requiring manufacturer discounts. Also under the IRA, starting on January 1, 2024, Medicare Part D was redesigned to cap beneficiary out-of-pocket costs and, beginning on January 1, 2025, Federal reinsurance will become 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 Medicare price increases outpace inflation. We began to accrue for rebate obligations on October 1, 2022 for Medicare Part D and on January 1, 2023 for Medicare Part B.
In addition to the IRA, other proposed U.S. policy actions focus on drug pricing, including the Most-Favored-Nations Prescription Drug Pricing Executive Order (MFN EO) that is aimed at using price benchmarks from other developed countries to set U.S. pricing targets, and the July MFN Letter that was delivered to a number of pharmaceutical companies, including Amgen. The July MFN Letter called for drug manufacturers to: 1) extend MFN pricing to Medicaid; 2) guarantee MFN pricing to Medicaid, Medicare and commercial payers on all newly launched drugs; 3) use future increased revenues from outside the U.S. to lower U.S. drug prices; and 4) participate in direct-to-patient models to provide MFN pricing for certain drugs. In December 2025, we announced that we are taking actions that satisfy the components outlined in the July MFN Letter, including the Administration’s MFN pricing requests. We also announced the expansion of our direct-to-patient program, AmgenNowTM, to include Aimovig and AMJEVITA, supplementing our existing offering of Repatha, all of which are available through AmgenNowTM and are expected to be available through TrumpRx following the platform’s launch. See Item 1A. Risk Factors—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.
Other potential policies cover a wide range of areas, including allowing the importation of drugs from other countries; increasing transparency in drug pricing; using third-party value assessments to determine drug prices; referencing foreign prices; and changes to government rebate programs. For example, on January 5, 2024, the FDA authorized Florida to move forward with its importation program proposal, which excludes biologics. Further, at the state level, eight states (Colorado, Maine, Maryland, Minnesota, New Hampshire, New Jersey, Oregon and Washington) have enacted laws that establish PDABs to identify drugs that pose affordability challenges, and in four states (Colorado, Maryland, Minnesota and Washington) include authority for the state PDAB to set upper payment limits on certain drugs for in-state patients, payers and providers.
In many countries outside the United States, government-sponsored healthcare systems are the main payers for drugs and biologics.In many countries other than the United States, government-sponsored healthcare systems are the primary payers for drugs and biologics. Governments and payers are using a range of tools to drive prices down, including mandatory price controls, international reference pricing, therapeutic-reference pricing, higher rebates, incentives for generics and biosimilars, and mandated price cuts. Pricing and reimbursement reforms under consideration in the United States—including proposals to expand government negotiation and increase payer leverage—may further amplify global pricing pressures, as many countries reference or react to U.S. pricing dynamics. Health technology assessment bodies increasingly evaluate the added benefit of new therapies, and these judgments shape reimbursement levels and coverage terms. Many countries also narrow coverage relative to product labels or impose volume caps to limit use. We expect governments to continue taking aggressive steps to reduce spending on drugs and biologics, and fiscal constraints may limit willingness to approve or provide access to innovative therapies and new technologies. Potential EU pharmaceutical legislation may also influence pricing and reimbursement frameworks, which could affect patient access.
The dynamics and developments discussed above create pressures on the pricing and potential usage of our products and on the industry. Given the diverse interests in play between payers, biopharmaceutical manufacturers, policy makers, healthcare providers and independent organizations, if and whether the parties involved can achieve alignment on the matters discussed above remain unclear, and the outcome of any such alignment is difficult to predict. We remain focused on pricing our products responsibly and delivering breakthrough treatments for unmet medical needs. Amgen is committed to working with the entire healthcare community to ensure continued innovation and to facilitate patient access to needed medicines. We do this by:
•investing billions of dollars annually in R&D;
12
•pricing our medicines to reflect the value they provide;
•developing more affordable therapeutic choices in the form of high-quality and reliably supplied biosimilars;
•partnering with payers to share risk and accountability for health outcomes;
•providing patient support and education programs;
•expanding patient access to our medicines, including through direct-to-patient channels;
•continuing to deliver a reliable supply of medicines through our additional investments in U.S. manufacturing;
•helping patients in financial need access our medicines; and
•working with policy makers, patients and other stakeholders to establish a sustainable healthcare system with access to affordable care and in which patients and their healthcare professionals are the primary decision makers.
