#### Dear Fellow Stockholder:
You are invited to attend the 2026 Annual Meeting of Stockholders, or Annual Meeting, of Amgen Inc. to be held on Tuesday, May 19, 2026, at 11:00 A.M., Pacific Time, via the internet at www.virtualshareholdermeeting.com/AMGN2026.

Our Mission: For more than 45 years, Amgen's mission has been to serve patients. Our innovative and biosimilar medicine portfolios are serving millions of patients globally, and therapies advancing through our pipeline address serious illnesses and unmet medical needs of a rapidly aging global population.

Execution of Our Strategy: 2025 was another year of strong execution, with 10% year-over-year revenue and sales growth, 18 of our products achieving record sales, 14 products exceeding $1 billion in sales, and 13 products delivering double-digit sales growth. We also delivered on an ambitious research and development program agenda, including receiving five important U.S. Food and Drug Administration (FDA) regulatory approvals and advancing the MariTide (maridebart cafraglutide) Phase 3 program in obesity and obesity-related conditions. Highlights for the year include:

• In General Medicine , our Phase 3 VESALIUS-CV study of Repatha<sup>®</sup> in patients at high cardiovascular (CV) risk without prior myocardial infarction or stroke showed that Repatha significantly reduced the risk of first major adverse CV events (by 25%) and first heart attack (by 36%), and data from real-world studies, including VESALIUS-REAL, provided real-world evidence supporting Repatha's use in low-density lipoprotein cholesterol management. For MariTide , we initiated and advanced six global studies under our broad Phase 3 clinical development program across four obesity and obesity-related conditions (chronic weight management, CV outcomes, heart failure, and obstructive sleep apnea), highlighting the potential impact of MariTide beyond weight loss.

• In Oncology , IMDELLTRA<sup>®</sup> received full FDA approval for second-line or later treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC), demonstrating its survival advantage over standard-of-care chemotherapy. LUMAKRAS<sup>®</sup> (in combination with Vectibix<sup>®</sup>) received FDA approval for third-line treatment of KRAS G12C-mutated metastatic colorectal cancer .

• In Rare Disease , UPLIZNA<sup>®</sup> received two FDA approvals, including as the first and only treatment for adults living with Immunoglobulin G4-related disease (IgG4-RD) and as a treatment of generalized myasthenia gravis (gMG).

• In Inflammation , TEZSPIRE<sup>®</sup> <sup>(1)</sup> received FDA approval for the treatment of chronic rhinosinusitis with nasal polyps. Two Phase 3 studies have been initiated and are enrolling patients with moderate to very severe chronic obstructive pulmonary disease (COPD), one of the leading causes of death in the world.

Manufacturing Excellence: Following our 2024 announcement of a $1 billion expansion of our North Carolina facilities, we continued to expand our U.S. manufacturing network in 2025, announcing additional investments of $900 million in Ohio and $650 million in Puerto Rico, to support increased drug production and the integration of innovative advanced process development technologies that are designed to significantly increase our yields. These expansions reinforce our long-standing commitment to U.S.-based biomanufacturing and are designed to enhance the resilience and flexibility of our global supply network.

Our Commitment to Our Patients and Communities: Through the Amgen Safety Net Foundation and our corporate philanthropy, we assist eligible patients around the world in obtaining the medicines they need but cannot afford. The science education programs funded by the Amgen Foundation have reached over 80 million students and teachers globally to date, helping to inspire the next generation of innovators.

Stockholder Engagement: Since our last annual meeting, we have engaged in governance-focused outreach activities and discussions with stockholders holding approximately 59% of our outstanding shares. We appreciate the thoughtful perspectives that our stockholders have provided in our year-round engagement activities. Feedback received during the course of these activities is shared with our Board and informs its decisions. We plan to continue this valuable dialogue with our investors in the coming year.

I look forward to sharing more about our Company at our Annual Meeting. In addition to the business to be transacted and described in the accompanying Notice of Annual Meeting of Stockholders, I will discuss recent developments during the past year, the substantial progress we made on our strategic priorities in 2025, and respond to comments and questions.

On behalf of our Board, I thank you for your participation and investment in Amgen. We look forward to the Annual Meeting on May 19.

Sincerely,

![LOGO](g13946g58k62.jpg)

Proxy Statement Summary

## Item 2: Advisory Vote to Approve Our Executive Compensation (Page 45)
Our executive compensation program is designed to reward and drive long-term performance in support of our strategy.

2025 Business Highlights

We delivered strong financial performance in 2025, with 10% growth in total revenues and sales (compared to 2024) with record full year sales for 18 products and continued to advance our innovative pipeline and expand our state-of-the-art manufacturing facilities, while executing on our capital allocation priorities.

Advanced Innovative Pipeline and Executed Key Clinical Studies

• We received five FDA approvals, including:

• In Rare Disease, UPLIZNA<sup>®</sup> was approved as the first and only treatment for adults living with Immunoglobulin G4-related disease (IgG4-RD) and for the treatment of generalized myasthenia gravis (gMG).

• In Oncology, IMDELLTRA<sup>®</sup> received full FDA approval for second-line or later treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC). LUMAKRAS<sup>®</sup> (in combination with Vectibix<sup>®</sup>) was approved for third-line treatment of KRAS G12C-mutated metastatic colorectal cancer.

• In Inflammation, TEZSPIRE<sup>®</sup> <sup>(1)</sup> was approved for the treatment of chronic rhinosinusitis with nasal polyps.

• We executed key clinical studies and advanced our robust pipeline of potential first- and/or best-in-class medicines:

• General Medicine : Our Phase 3 VESALIUS-CV study of Repatha<sup>®</sup> in patients at high cardiovascular (CV) risk without prior myocardial infarction or stroke demonstrated that Repatha reduced the risk of first major adverse CV events (by 25%) and first heart attack (by 36%). We initiated a Phase 3 primary prevention CV outcomes study of olpasiran which is enrolling patients with elevated lipoprotein(a) (Lp(a)) and at risk for a first major CV event. For MariTide (maridebart cafraglutide), we initiated and advanced six global Phase 3 studies under our broad MariTide clinical development program across four obesity and obesity-related conditions (chronic weight management, CV outcomes, heart failure, and obstructive sleep apnea). We reported results from Part 2 of the Phase 2 chronic weight management that showed that the large majority of participants maintained the weight loss achieved in Part 1 for an additional 52 weeks on a lower monthly dose or quarterly dose of MariTide. Additionally, we also announced that the Phase 2 study for the treatment of Type 2 diabetes in adults living with and without overweight or obesity also demonstrated robust and clinically meaningful reductions in both HbA1c and weight.

• Rare Disease : TEPEZZA<sup>®</sup> received European Commission approval for the treatment of adults with moderate to severe thyroid eye disease. Both Phase 3 studies of dazodalibep in Sjögren's disease are progressing following completion of enrollment.

• Oncolog y : We continue to advance a comprehensive, global clinical development program for IMDELLTRA , currently composed of eight studies across ES- and limited-stage SCLC in various phases, including three Phase 3 studies.

• Inflammation : For TEZSPIRE <sup>(1)</sup>, two Phase 3 studies are enrolling patients with moderate to very severe chronic obstructive pulmonary disease (COPD), and a Phase 3 study for the treatment of eosinophilic esophagitis has completed enrollment.

• In our early pipeline, we progressed nine new discovery-stage research programs and initiated 13 first-in-human studies.

Expanding Our State-of-the-Art Manufacturing and Research and Development Facilities

• Following our 2024 announcement of a $1 billion expansion of our North Carolina facilities, we continued to expand our U.S. manufacturing network in 2025, announcing additional investments of $900 million in Ohio and $650 million in Puerto Rico , to support increased drug production and the integration of innovative advanced technologies that are designed to significantly increase our yields. These expansions reinforce our long-standing commitment to U.S.-based biomanufacturing and are designed to enhance the resilience and flexibility of our global supply network. In 2025, we also broke ground on a $600 million center for science and innovation in California to accelerate our discovery of innovative medicines addressing high unmet medical needs.

Technology and Workforce

• To unlock new capabilities, enhance productivity, and accelerate future innovation, we invested in general upskilling for our staff on skills for the future, including AI, and we delivered measurable progress across end-to-end process innovation, technological advancement, and workforce transformation initiatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br> **In 2025, while investing $7 billion in research and development and $2 billion in capital expenditures,**<br> **we reduced our debt outstanding by $6 billion and returned $5 billion of capital to our stockholders in dividends.**<br>

<sup>(1)</sup> TEZSPIRE is being developed in collaboration with AstraZeneca plc.

## Item 4: Stockholder Proposal – Independent Board Chairman (Page 113)
Stockholder proposal to require an independent Board Chairman, if properly presented.

• Independent Oversight. Our Company has numerous mechanisms that ensure independent oversight of the Company's affairs and that facilitate communication with, and an independent evaluation of, senior management.

• Leadership Structure. Our governance documents give the Board discretion in determining whether to separate or combine the roles of the Chairman and Chief Executive Officer. This flexibility permits the Board to choose a leadership structure that can be tailored to the strengths of the Company's officers and directors at the time and to best address our evolving and highly complex business.

• Annual Evaluation of Leadership Structure. The Board conducts annual evaluations of the Company's leadership structure and determined that the Company and its stockholders are best served at this time by having Mr. Bradway serve as both Chairman and Chief Executive Officer, coupled by a separate active lead independent director, currently served by Robert A. Eckert.

• Active Experienced Lead Independent Director with Robust Responsibilities. We have an active lead independent director elected annually by and from the independent directors and strong Board and committee involvement to provide sound and robust oversight of management. The responsibilities of the lead independent director are well defined, as discussed on pages 24-26. The lead independent director engages in regular communication with the independent directors, including in independent directors sessions.

• Strong 2025 Performance Under the Board's Leadership Structure. In 2025, despite the headwinds cited in the proposal as a rationale for changing the Board's leadership structure, the Company delivered strong performance and robust financial results, including 10% year-over-year revenue and sales growth, with 18 products achieving record sales, 14 products exceeding $1 billion in sales, and 13 products delivering double-digit sales growth, and made meaningful progress on our strategic priorities, including advancing our innovative pipeline and securing five U.S. Food and Drug Administration approvals. Our strong cash flows and balance sheet in 2025 allowed us to make significant investments for long-term growth, including investing approximately $7 billion in research and development and $2 billion in strategic capital projects, while also reducing our debt outstanding by $6 billion and returning $5 billion of capital to our stockholders in dividends (including a 6% increase in our year-over-year quarterly dividend per share). Our performance in 2025 demonstrated the effectiveness of our Board leadership structure and its oversight of the Company's strategy and execution.

• Commitment to Stockholder Rights. We maintain meaningful stockholder rights and regularly review our corporate governance practices with the Board in light of investor feedback and evolving market practices. These stockholder rights include a single class of shares with equal voting rights, proxy access, action by written consent, the right to call special meetings, no supermajority vote provisions, and no poison pill.

## Corporate Governance
Board of Directors Corporate Governance Highlights

Our Board of Directors, or Board, is governed by our Amgen Board of Directors Corporate Governance Principles which are reviewed annually and modified from time to time, as necessary, to incorporate certain current best practices in corporate governance. Our Corporate Governance Principles may be found on our website at www.amgen.com.<sup>(1)</sup> The Board's corporate governance practices and stockholder rights include the following:

#### Board Governance Practices
&nbsp;&nbsp;&nbsp;&nbsp;• Lead Independent Director. The independent members of the Board elect a lead independent director on an annual basis. The lead independent director has robust responsibilities and authorities as discussed below. Robert A. Eckert currently serves as our lead independent director. Mr. Eckert has been our lead independent director since May 2016 and was re-elected by our Board on March 4, 2026 to serve as lead independent director, subject to his re-election to the Board by our stockholders at our 2026 Annual Meeting of Stockholders, or Annual Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;• Regular Executive Sessions of Independent Directors. Our independent directors meet privately on a regular basis. Our lead independent director presides at such meetings.

&nbsp;&nbsp;&nbsp;&nbsp;• Board Access to Management. We afford our directors ready access to our management. Key members of management attend Board and committee meetings to present information concerning various aspects of the Company, its operations, and results, and have regular meetings in executive sessions with the Board and committees. In addition, our directors have one-on-one meetings with leaders of various functions and attend certain broader Company meetings (such as our annual executive director and officer's meeting at which we align around the Company's strategic priorities for the year).

&nbsp;&nbsp;&nbsp;&nbsp;• Board Authority to Retain Outside Advisors. Our Board and its committees have the authority to retain independent advisors and counsel. The Audit Committee has the sole authority to appoint, compensate, retain, and oversee the independent registered public accountants. The Compensation and Management Development Committee, or

Compensation Committee, has the sole authority to appoint, compensate, retain, and oversee compensation advisors for senior management compensation review. The Governance and Nominating Committee, or Governance Committee, has the sole authority to appoint, retain, and replace search firms to identify director candidates and compensation advisors for our directors' compensation review. <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Independent Board Members on Key Standing Committees.

The Board has four key standing committees:

– Governance Committee;

– Audit Committee;

– Corporate Responsibility and Compliance Committee, or Compliance Committee; and

– Compensation Committee.

Each director on key standing committees has been determined by the Board to be independent under The NASDAQ Stock Market listing standards and the requirements of the Securities and Exchange Commission, or SEC.

&nbsp;&nbsp;&nbsp;&nbsp;• Regular Board and Committee Evaluations. The Board and the Audit, Compensation, Compliance, and Governance Committees each conduct an annual evaluation process. We provide more information regarding the Board and committee evaluations on page 33.

&nbsp;&nbsp;&nbsp;&nbsp;• Management Succession Oversight. Our Board oversees Chief Executive Officer, or CEO, and senior management succession planning. Directors engage with potential CEO, executive, and senior management successors at Board and committee meetings and in other business settings. The Compensation Committee has an effective process for monitoring and determining our CEO's compensation and performance and holds sessions on succession at least annually. All independent members of the Board are invited to attend the Compensation Committee sessions on succession. Our Board also establishes steps to address succession to respond to unexpected vacancies in the event of an emergency.

&nbsp;&nbsp;&nbsp;&nbsp;• Solicitation of Stockholder Perspectives. The Board believes that engagement with stockholders is a source of valuable information and perspectives on the Company. The Board has requested that management solicit input from investors on behalf of the Board, and the lead independent director also meets directly with stockholders when appropriate. We provide more information regarding our stockholder engagement program on page 58.

&nbsp;&nbsp;&nbsp;&nbsp;• Majority Approval Required for Director Elections. If an incumbent director up for re-election at a meeting of stockholders fails to receive a majority of the votes cast in favor for his or her election in an uncontested election, the Board will adhere to the director resignation policy as provided in our Amended and Restated Bylaws of Amgen Inc., or Bylaws. We provide more information on our majority voting standard on page 125.

&nbsp;&nbsp;&nbsp;&nbsp;• Director Limitation on Number of Boards and Annual Review of Director Commitment Levels. A director who is currently serving as our CEO should not serve on more than two outside public company boards. No director should serve on more than five public company boards (Amgen plus four outside boards). As part of its nominating process, the Governance Committee conducts an annual review of director commitment levels and shares its findings with the Board. Currently, our CEO serves on one outside public company board and no director serves on more than two outside public company boards.

&nbsp;&nbsp;&nbsp;&nbsp;• Continuous Board Refreshment. We have appointed eight new members to our Board since 2016 and our average Board tenure for our director nominees is approximately 8 years. Given the complexity and long-cycle nature of our business, the Board believes that the institutional knowledge our directors develop over time further strengthens their ability to provide effective oversight, particularly as our pipeline programs advance through multi-year drug discovery and development cycles. The Governance Committee and Board consider diversity in their determinations of director candidates and seek representation across a range of attributes. Diversity is broadly construed to take into consideration many factors, including industry knowledge, operational experience, scientific and academic expertise, geography, and personal background.

&nbsp;&nbsp;&nbsp;&nbsp;• Director Retirement Age. In consideration of the long-cycle nature of our business, and after careful deliberation and review of market practices, in 2025, the Board removed the mandatory retirement age

provision from our Corporate Governance Principles. The Board believes that a mandatory retirement age may limit the contributions of otherwise qualified and effective directors who can continue to provide meaningful, independent oversight and advice beyond an arbitrary age. We continue to focus on Board composition that balances shorter- and longer-tenured directors, supporting both fresh perspectives on the Company's business and risk profile informed by recent external experience and a deep understanding of the Company. <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Director Changes in Circumstances Actively Evaluated. If a director has a significant change in principal business or professional affiliation or responsibility, including a change in principal occupation, he or she shall offer his or her resignation to the Chair of the Governance Committee.

If the affected director is the Chair of the Governance Committee, he or she may offer his or her resignation to the Chair of the Board or the lead independent director. The Governance Committee then determines whether to accept the resignation based on what it believes to be in the best interests of the Company and our stockholders. Directors notify the Chair of the Governance Committee prior to accepting an invitation to serve on a public or private company board to permit the Governance Committee to evaluate the relationship for a potential conflict of interest and to confirm that the director continues to have time available to perform his or her duties. <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Director Outside Relationships Require Pre-Approval. Without the prior approval of disinterested members of the Board, directors should not enter into any transaction or relationship with the Company in which they will have a financial or a personal interest or any transaction that otherwise involves a conflict of interest.

&nbsp;&nbsp;&nbsp;&nbsp;• Active Management of Director Conflicts of Interest. If an actual or potential conflict of interest arises for a director or a situation arises giving the appearance of an actual or potential conflict, the director must promptly inform the Chairman of the Board or the Chair of the Governance Committee. All directors are expected to recuse themselves from any discussion or decision found to affect their personal, business, or professional interests.

#### Stockholder Rights
&nbsp;&nbsp;&nbsp;&nbsp;• Single Class of Shares. We have a single class of shares with equal voting rights. One share equals one vote.

&nbsp;&nbsp;&nbsp;&nbsp;• Proxy Access. Our Bylaws permit proxy access for director nominations. Eligible stockholders with an ownership threshold of 3% who have held their shares for at least 3 years and who otherwise meet the requirements set forth in our Bylaws may have their nominees up to the number of directors constituting the greater of 20% of the total number of directors or two nominees of our Board included in our proxy materials. Up to 20 eligible stockholders may group together to reach the 3% ownership threshold. In the course of designing our proxy access provisions, we carefully considered each element in the interest of our stockholders as a whole, including that the number of stockholders who may group together (20) would afford those stockholders likely to utilize proxy access with the opportunity to do so.

&nbsp;&nbsp;&nbsp;&nbsp;• Action by Written Consent. Our Amgen Inc. Restated Certificate of Incorporation permits stockholders to act

by written consent in lieu of a meeting upon the request of the holders of at least 15% of our outstanding common shares who otherwise meet the requirements of our Certificate of Incorporation. <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Special Meetings. Our Bylaws permit stockholders to request that the Company call a special meeting upon the written request of the holders of at least 15% of our outstanding common shares who otherwise meet the requirements set forth in our Bylaws.

&nbsp;&nbsp;&nbsp;&nbsp;• No Supermajority Vote Provisions. We have a simple majority voting standard to amend our Certificate of Incorporation and Bylaws.

&nbsp;&nbsp;&nbsp;&nbsp;• No Poison Pill. We do not have a shareholder rights plan, or poison pill.

Board Leadership Structure

Our current Board leadership structure and governing documents permit the roles of Chairman and CEO to be filled by the same or different individuals.

Annual Evaluation of Board Leadership Structure and Annual Election of Lead Independent Director. The Board evaluates the leadership structure annually. As part of this annual evaluation process, the Board reviews its leadership structure, including whether combining or separating the roles of Chairman and CEO is in the best interests of the Company and our stockholders. The Board also considers:

&nbsp;&nbsp;&nbsp;&nbsp;• The effectiveness of the policies, practices, and people in place at the Company to help ensure strong, independent Board oversight;

&nbsp;&nbsp;&nbsp;&nbsp;• The Company's performance and the effect the leadership structure could have on its performance;

&nbsp;&nbsp;&nbsp;&nbsp;• The Board's performance and the effect the leadership structure could have on the Board's performance;

&nbsp;&nbsp;&nbsp;&nbsp;• The Chairman's performance in the role;

&nbsp;&nbsp;&nbsp;&nbsp;• The lead independent director's performance in the role;

&nbsp;&nbsp;&nbsp;&nbsp;• The views of the Company's stockholders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• The practices at other companies and trends in governance.

In the circumstance that the Board determines that it remains in the best interests of the Company and its stockholders that the CEO serve as Chairman, the independent members of the Board then elect a lead independent director from the independent members of the Board. The last review was completed in March 2026, and as a result of such review, the Board has determined that it continues to be in the best interests of the Company and our stockholders to have Robert A. Bradway, our CEO and President, serve as Chairman, coupled with an active lead independent director. As such, Mr. Bradway holds the position of Chairman, CEO, and President, and Mr. Eckert serves as the lead independent director.

Overview of Lead Independent Director Responsibilities. The responsibilities of the lead independent director are well defined. The lead independent director engages in regular communication with the independent directors, including in independent directors sessions. The lead independent director keeps Mr. Bradway apprised of any concerns, issues, or determinations made during the independent directors sessions, and consults with Mr. Bradway on other matters pertinent to the Company and the Board.

Corporate Governance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br> Lead Independent Director Responsibilities<br>The lead independent director's responsibilities outlined in our Corporate Governance Principles include:<br>• Approving meeting agendas for the Board;<br>• Assuring that there is sufficient time for discussion of all meeting agenda items;<br>• Previewing the information to be provided to the Board;<br>• Having the authority to call meetings of the independent directors;<br>• Organizing and leading the Board's evaluation of the CEO;<br>• Serving as a liaison between the Chairman and the independent directors;<br>• Leading the Board's annual self-evaluation;<br>• Ensuring that he/she is available for consultation and direct communication, if requested by major stockholders; and<br>• Presiding at meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors.<br>

In addition to the responsibilities outlined above, our lead independent director also:

&nbsp;&nbsp;&nbsp;&nbsp;• Meets with the Chairman prior to each regular meeting of the Board and its committees to discuss, provide input on, and approve the agendas;

&nbsp;&nbsp;&nbsp;&nbsp;• Helps the Chairman determine who attends Board meetings, such as members of management or outside advisors and presenters;

&nbsp;&nbsp;&nbsp;&nbsp;• Has one-on-one discussions with each independent director, including as part of the Board's annual self-evaluation process;

&nbsp;&nbsp;&nbsp;&nbsp;• At his discretion, attends committee meetings, including those committees for which he is not a member, and has access to all committee materials;

&nbsp;&nbsp;&nbsp;&nbsp;• Attends significant management events (such as our annual executive director and officer's meeting at which we align around the Company's strategic priorities for the year), providing opportunities for leadership effectiveness assessments;

&nbsp;&nbsp;&nbsp;&nbsp;• Has the authority to engage independent consultants;

&nbsp;&nbsp;&nbsp;&nbsp;• Is regularly apprised of inquiries from stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;• Interviews Board candidates; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• Has an increased role in crisis and risk management, as appropriate.

**Independent Directors Roles and Responsibilities***.* Our highly independent Board (11 of our 12 director nominees) possesses a deep and broad set of skills and experiences.

Independent Directors Sessions. A meeting of the independent directors is scheduled at every regular Board meeting to allow the independent directors to meet in an executive session without Mr. Bradway to review matters, including Company performance, management effectiveness, proposed programs and transactions, and the Board meeting agenda items. These independent sessions are organized and chaired by our lead independent director, who provides direct feedback to Mr. Bradway after these executive sessions.

Independent Committee Leadership. The Audit, Compensation, Compliance, and Governance Committees are each composed solely of, and led by, independent directors and provide independent oversight of management and its Board-delegated duties. In addition:

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee Chair meets with management in advance of meetings to review and refine agendas, add topics of interest, and review and comment on materials to be delivered to the committee;

&nbsp;&nbsp;&nbsp;&nbsp;• At each regular meeting of the full Board, each committee Chair provides a report summarizing recent committee meetings;

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee meeting includes adequate time for executive session to allow the committees to meet in executive session on a regular basis with no members of management present (unless otherwise requested by the committee);

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee effectively manages its Board-delegated duties and communicates regularly with the Chairman, lead independent director, the Board, and members of management; and

&nbsp;&nbsp;&nbsp;&nbsp;• Every director has access to all committee materials.

Corporate Governance Structure. The Board believes our corporate governance structure, with its strong emphasis on independence, an active lead independent director, and strong Board and committee involvement, provides sound and robust oversight of management.

Flexibility of the Leadership Structure. The Board is committed to high standards of corporate governance. The Board values its flexibility to select its optimal leadership structure to best serve the Company's and stockholders' interests based on the qualifications of individuals available, circumstances existing at the time,

ï *2026 Proxy Statement*25

##### [**Table of Contents**](#toc)
Corporate Governance

and the Company's particular needs. As such, the Board annually evaluates whether combining or separating the roles of Chairman and CEO is in the best interests of the Company and our stockholders.

Benefits of Combined Leadership Structure. Following the annual evaluation of the governance structure, the Board continues to believe that the Company and our stockholders are best served by having Mr. Bradway in the role of Chairman (subject to his re-election to the Board) and CEO for the following reasons:

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Bradway is most familiar with our business and the unique challenges we face. His day-to-day insight into our challenges facilitates timely deliberation by the Board on important matters.

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Bradway has and will continue to identify agenda items important for the Board's understanding and oversight and lead effective discussions on the important matters affecting our business, prospects and results. His knowledge and extensive experience regarding our operations and the highly regulated industries and markets in which we compete position

him to identify and prioritize matters for Board review and deliberation.

&nbsp;&nbsp;&nbsp;&nbsp;• As Chairman and CEO, Mr. Bradway serves as an important bridge between the Board and management and provides critical leadership for carrying out our strategic priorities and confronting our challenges. The Board believes that Mr. Bradway brings a unique, stockholder-focused insight to assist the Company to most effectively execute its strategy and business plans to maximize stockholder value.

&nbsp;&nbsp;&nbsp;&nbsp;• The strength and effectiveness of the communications between Mr. Bradway as our Chairman and Mr. Eckert as our lead independent director result in comprehensive Board oversight of the issues, plans, and prospects of our Company.

&nbsp;&nbsp;&nbsp;&nbsp;• This leadership structure provides the Board with more complete and timely information about the Company, a unified structure and consistent leadership direction internally and externally, and results in a collaborative and collegial environment for Board decision making.

The Board's Role in Risk Oversight

Our Board oversees an enterprise-wide approach to risk management, which is designed to support execution of our strategy and achievement of the Company's objectives to improve long-term operational and financial performance and enhance stockholder interests. Our Board believes that a fundamental part of risk management is understanding the risks that we face, adopting appropriate controls and mitigation activities for such risks, monitoring these risks, and responding to emerging developments for such risks.

We have an Enterprise Risk Management, or ERM, program, to identify, assess, manage, monitor, and report enterprise-level risks that may affect our ability to achieve the Company's objectives. Annually, we evaluate the greatest risks to our business, their underlying risk drivers, and the associated mitigation activities, maturity, and controls. Our Enterprise Risk Council, or ERC, a cross-functional group of the Company's business leaders representing all key business functions, governs the ERM program and works to identify and assess risks that meet the pre-established criteria constituting an enterprise-level risk, and confirm that there is clear accountability and appropriate mitigation plans are in place, including monitoring and reporting. The ERM program is overseen by our Executive Vice President and Chief Financial Officer, and the ERC is chaired by our Chief Compliance Officer. Additionally, emerging risks that do not rise to the level of enterprise-level risks, are assessed, discussed, and actively managed and monitored. We believe that the

areas of risk that are fundamental to the success of our enterprise and rise to enterprise-level risks include product development, safety and surveillance, supply and quality, value (which includes pricing) and access, sales and promotion, and business development, as well as protecting our assets (financial, intellectual property, and information and technology, including artificial intelligence (AI) and cybersecurity), all of which are managed by senior executive management reporting directly to our CEO. The enterprise-level risks are overseen by the Board and the appropriate Board committee (as discussed further below). The Board receives regular risk reporting from senior management, including an annual detailed review of the ERM program and key enterprise-level and emerging risks, as well as, as appropriate, during the Board's strategic planning activities, budget reviews and approvals, capital plan reviews and approvals, and through reviews of compliance issues at the applicable Board committees. For topics allocated to specific committees for their oversight (as discussed below), that committee's Chair oversees the committee's annual calendar and meeting agendas so that the Company's activities in support of its compliance are assessed regularly. Committee activities and discussions are reported to the Board by each of the committee Chairs for the Board's information and oversight at every regular Board meeting, and more frequently as needed, and such reports can provide additional detail on risk management issues and management's response.

Process for Selecting Directors and Director Qualifications

Board Composition. Board composition is one of the most critical areas of focus for the Board. Reflecting our Board's commitment to refreshment, the Board has appointed eight new directors since 2016.

Our Governance Committee regularly screens and recommends candidates for nomination by the full Board and, among other things, considers feedback received during the annual Board and committee evaluation process, investor feedback, our qualification guidelines and skills matrix, director commitment levels (with consideration given to public company leadership roles and outside commitments) and diversity. The Governance Committee will consider recommendations for director candidates made by stockholders and evaluate them using the same criteria as for other candidates.

Director Qualifications and Backgrounds. Our Governance Committee is responsible for determining Board membership qualifications and for selecting, evaluating, and recommending to the Board nominees for annual election to the Board and to fill vacancies as they arise. The Governance Committee reviews regularly and reports to the Board on the composition and size of the Board, and makes recommendations, as necessary, so that the Board maintains at least the minimum number of independent directors and the composition requirements of the Audit and Compensation Committees required by applicable laws and regulations, and reflects the appropriate balance of knowledge, experience, skills, expertise, and personal background advisable for the Board as a whole.

The Governance Committee and Board consider diversity in their determinations of director candidates, and seek representation across a range of attributes.

The Governance Committee determines and oversees guidelines for selecting nominees to serve on the Board and for considering stockholder recommendations for nominees. The Amgen Inc. Board of Directors Guidelines for Director Qualifications and Evaluations are included in this proxy statement as **Appendix A**.

Among other things, under the Board of Directors Guidelines for Director Qualifications and Evaluations, each Board member must possess:

&nbsp;&nbsp;&nbsp;&nbsp;• A demonstrated breadth and depth of management and leadership experience;

&nbsp;&nbsp;&nbsp;&nbsp;• Financial and/or business acumen or relevant industry or scientific experience;

&nbsp;&nbsp;&nbsp;&nbsp;• Integrity and high ethical standards;

&nbsp;&nbsp;&nbsp;&nbsp;• Sufficient time to devote to the Company's business;

&nbsp;&nbsp;&nbsp;&nbsp;• The ability to oversee, as a director, the Company's business and affairs for the benefit of our stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;• The ability to comply with the Amgen Board of Directors' Code of Conduct; and

&nbsp;&nbsp;&nbsp;&nbsp;• A demonstrated ability to think independently and work collaboratively.

#### Continuous Board Refreshment
Our Board is committed to strong refreshment practices to continuously align the composition of the Board and its leadership structure with our long-term strategic needs. The Board, led by the Governance Committee, has an ongoing process for identifying, evaluating, and selecting directors, and these decisions are also informed by the annual Board and committee evaluation process

described below. Our Governance Committee uses a variety of methods to help identify potential Board candidates and considers an assessment of current Board skills, background, diversity, independence, experience, tenure, and anticipated retirements to identify gaps that may need to be filled through the Board refreshment process.

#### Director Education
Our Board believes that director education is important to the ability of directors to fulfill their roles and supports Board members in their continuous learning. The Board encourages directors to participate in continuing education programs, and we reimburse directors for their expenses associated with this participation. During Board and committee meetings, as well as sessions to discuss

strategy, education and information sessions are provided on specific subjects by internal and external experts. New directors also participate in our director orientation program. Additionally, at the director's discretion, directors may attend any committee meetings, including those committees for which he or she is not a member, and have access to all committee materials.

Regular Board and Committee Evaluations

Board and committee evaluations play a critical role in supporting the effective functioning of our Board. Through evaluations, our directors review where they

believe our Board functions effectively and, importantly, areas where our Board thinks there may be opportunities for improvement, including through Board refreshment.

![LOGO](g13946g00v16.jpg)

Annual Board and Committee Evaluation Process The Governance Committee oversees the Board evaluation process. In consultation with our lead independent director, and the committee Chairs, a framework for evaluation is established, including a review of topics for evaluation that are incorporated in the evaluation forms used by the Board and committees. Committee Evaluations and Assessment Formal annual anonymous evaluations of the Audit, Compensation, Compliance, and Governance Committees are collected, compiled, and distributed in advance of the scheduled discussion by each committee in executive session (typically in October). The evaluations include open-ended questions and space for candid commentary. All comments are unattributed, included verbatim, and shared with the full Board and each applicable committee. Each committee Chair reports to the full Board on these assessments for review and discussion. One-on-One Discussions Our lead independent director conducts one-on-one discussions with each independent director. These candid conversations allow for direct and honest feedback on varied aspects of our Board's operations. Board Evaluation and Assessment Annual anonymous evaluations of the Board are collected, compiled, and distributed in advance of the scheduled discussion by the full Board in executive session (typically in December) and informed by the results of the committee-level evaluation discussions as well as the one-on-one discussions conducted by the lead independent director. Follow-Up Policies, practices, and the composition of our Board and its committees are modified, as appropriate, based on evaluation findings and one-on-one discussions, and follow-up items are discussed at subsequent Board and committee meetings. Ongoing Our directors are encouraged to convey ongoing feedback to our lead independent director or the Governance Committee during any executive session throughout the year.

Evaluation Results. The Audit, Compensation, Compliance, and Governance Committees each completed their committee evaluations and assessments in October 2025 and such evaluations were included as part of the total evaluation by the Governance Committee in December 2025. The Board completed its evaluation in December 2025. Each committee and the Board was considered to be operating effectively, and each committee and the Board was satisfied with its performance.

**Ongoing Feedback***.* Our directors provide real-time feedback throughout the year outside of the formal evaluation process and have open access to management and third-party advisors. Additionally,

executive sessions of directors (without management) are scheduled for every regular Board and committee meeting to identify any issues and assess whether meeting objectives were satisfied.

Changes Implemented. Based on the annual Board and committee evaluation process, ongoing feedback provided by directors, and one-on-one discussions between our lead independent director and each independent director, changes to Board practices have included additional presentations and education on various topics, such as AI and strategy, Board visits to certain of our facilities, and the addition of new directors.

Director Independence

At least annually, the Governance Committee reviews the independence of each non-employee director and makes recommendations to the Board and the Board affirmatively determines whether each director qualifies as independent. Each director must keep the Governance Committee fully and promptly informed as to any development that may affect the director's independence.

The Board has determined that each of our non-employee directors: Wanda M. Austin; Michael V. Drake; Brian J. Druker; Robert A. Eckert; Greg C. Garland; Charles M. Holley, Jr.; S. Omar Ishrak; Tyler Jacks; Mary E. Klotman; Ellen J. Kullman; and Amy E. Miles was independent during 2025 under The NASDAQ Stock Market listing standards and the requirements of the SEC. Mr. Bradway is not independent based on his service as our CEO and President. Mr. Bradway is the only director who also serves in a management capacity. In making its independence determinations, the Board reviewed direct and indirect transactions and relationships between each director or any member of his or her immediate family, and us or any of our subsidiaries or affiliates based on information provided by the director, our records, and/or publicly available information.

All of the reviewed transactions and arrangements were entered into in the ordinary course of business and none of the business transactions, donations, or grants involved an amount that (i) exceeded the greater of 5% of the recipient entity's revenues or $200,000 with respect to transactions where a director or any member of his or her immediate family or spouse served as an employee, officer, partner, director, or controlling shareholder, or (ii) exceeded $10,000 with respect to professional or consulting services provided by entities at which directors serve as professors or employees.

The following types and categories of transactions, relationships, and arrangements were considered by our Board in making its independence determinations:

&nbsp;&nbsp;&nbsp;&nbsp;• Each of the independent directors (or their immediate family members) currently serves or has previously served within the last three years as a professor, trustee, director, or member of a board, advisory

board, council, or committee for one or more colleges, universities, or non-profit charitable organizations, including research or scientific institutions, to which the Amgen Foundation has made grants or matching donations under the Amgen matching gift program that is available to all of our employees and directors. <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Each of the independent directors (or their immediate family members) currently serves, or has previously served within the last three years, as a member of the board of directors, the board of trustees, or an advisory board for an entity with which Amgen has business transactions or to which Amgen or the Amgen Foundation makes donations or grants. These business transactions include, among other things, purchasing of scientific, office, and computing supplies and equipment, software licenses, and expenses relating to repair and maintenance, clinical trials, research and development, sponsorship of healthcare programs, internship programs, and conferences, and reimbursement of business-related expenses incurred by our staff (such as for transportation, gas, and food purchases).

&nbsp;&nbsp;&nbsp;&nbsp;• Wanda M. Austin, Michael V. Drake, Brian J. Druker, and Tyler Jacks currently serve as professors for universities, and Mary E. Klotman currently serves as the Duke University Executive Vice President for Health Affairs and the Dean of Duke's School of Medicine, to which Amgen has made payments for certain business transactions such as license agreements<sup>(1)</sup>, symposiums, conferences, and exhibits, postdoctoral research programs, clinical trials, training, and research and development, software licenses and maintenance, as well as for grants from the Amgen Foundation.

None of these directors, directly or indirectly, provides any professional or consulting services to us and none of the directors currently has or has had any direct or indirect material interest in any of the above transactions and arrangements. The Board determined that these transactions and arrangements did not warrant a determination that any of our non-employee directors were not independent.

<sup>(1)</sup> As part of our acquisition of Horizon Therapeutics plc on October 6, 2023, we acquired pre-existing license agreements with academic institutions associated with certain of our directors.

Our Sustainability Highlights

Our responsibility to operate as a good corporate citizen begins with our mission to serve patients and is supported by our long-standing focus on using resources responsibly to support the sustainability of our business and the environment.

#### Oversight and Governance
Our sustainability efforts are governed at the highest levels and include Board and committee oversight, executive-level leadership, and subject-matter experts who lead initiatives across our business.

Board Oversight. The Board and its applicable committees provide guidance to, and oversight of, management with respect to sustainability matters. The Compliance Committee assists the Board in overseeing our activities in areas that include environmental sustainability and access to medicines. The Compensation Committee provides oversight of our approach to human capital resources management, including our talent strategy and organizational culture. The Governance Committee oversees the Company's corporate governance activities and Board membership. The Audit Committee provides oversight of our disclosure controls and procedures, including those that support our reporting in the area of sustainability.

Additionally, management shares feedback received from our stockholders with the Board, including in connection with our governance-focused engagement program. (For additional information, please see "Feedback From Our Stockholders and Responsive Actions Taken by Our Board" on page 58 of our Compensation Discussion and Analysis.)

Management Leadership. A cross-functional, executive-level governance council sets our overall sustainability strategy, provides guidance on program implementation, and oversees the continuing enhancement of our programs. This council also evaluates current and emerging sustainability-related compliance and risk topics that are relevant to our business. (For additional information, please see "The Board's Role in Risk Oversight" previously discussed.)

Our sustainability framework includes three pillars—Healthy Patients and Communities, Healthy Planet, and Healthy Amgen—that serve as organizing principles to address these areas in a holistic way across our business.

Our Framework

![LOGO](g13946g00v17.jpg)

Program Implementation. Our sustainability council is supported by a steering committee that oversees the execution of our sustainability strategy and programs. With the oversight of our executive leadership, individual programmatic elements are managed at a business function level.

In addition to our history of strong corporate governance practices, we pursue initiatives intended to enhance the sustainability and resilience of our business and the communities and healthcare systems on which patients rely. Examples described below include initiatives to advance science education and inspire the next generation of scientists; expand access to our medicines and support efforts to strengthen healthcare systems to better serve patients in need worldwide; and further improve and optimize our highly resource efficient biomanufacturing operations.

#### Environmental Sustainability
As a science-based company committed to advancing human health, Amgen has a long-standing objective to conduct environmentally responsible operations and we regularly set targets to challenge ourselves to deliver further improvements. Since 2007, we have successfully advanced our environmental sustainability program while substantially increasing our global production capacity and patient reach.

Building on the successful execution of our 2013-2020 conservation targets, our 2021-2027 environmental sustainability plan (our third since 2007) includes a target of achieving carbon neutrality in our operations by 2027, while also aiming to further reduce our water use (by 40%) and waste disposed (by 75%).<sup>(1)</sup> Our carbon emissions reduction targets have been approved by the Science Based Targets Initiative (SBTi).

Our 2027 Environmental Sustainability Plan. To achieve our 2027 goals, we are harnessing our innovative capabilities to become, not just more environmentally sustainable, but also more flexible and productive, resulting in reductions in operating costs from such efficiencies over the same period.

<sup>(1)</sup> Carbon neutrality goal refers to Scope 1 and 2. Reductions in waste and water take into account only verified reduction projects, do not take into account changes associated with the contraction or expansion of the Company, and are measured against a 2019 baseline.

##### [**Table of Contents**](#toc)
Corporate Governance

Our 2027 plan is designed to drive specific environmental sustainability projects across our operations, including continued investment in our innovative and resource efficient approach to biomanufacturing, smart and integrated facility design, use of on-site solar and other renewable energy sources, electric vehicle fleet conversion, treatment and reuse of water, the reduction and recycling of single-use plastics, and the reduction of consumables packaging. In support of our goal of achieving carbon neutrality by 2027<sup>(1)</sup>, Amgen is pursuing a disciplined approach that integrates environmental sustainability with operational efficiency. We are focusing on innovative technologies and efficiency projects designed to reduce carbon emissions from our owned and operated facilities, lower energy consumption, and drive cost savings and operational resilience, in addition to sourcing renewable energy. Where renewable sources are not feasible, we prioritize offsetting based on the quality of the credit or offset. (For more information, please see our California AB1305 Disclosure available at www.amgen.com.<sup>(2)</sup>)

Sustainability by Design. Amgen helped to invent the processes and tools that created the global biotech industry. As we continue to grow and innovate, we have pioneered advanced technologies and are continuing to implement more environmentally responsible approaches throughout the Company that also reduce costs and increase operational efficiency. Through Amgen Ecovation™, our approach to innovative and sustainable manufacturing, we embed sustainability principles into the design, development, and construction of new laboratory, manufacturing, and administrative buildings.

This innovative approach to biomanufacturing reduces the scale and costs of making biologic medicines, and reduces water and energy use, while maintaining a reliable, high-quality, compliant supply of medicines. Features currently being employed under this approach include enhanced utility monitoring, fully or highly electrified plants, onsite renewable power, yield-driven resource conservation, heat-recovery chillers, reverse osmosis water filtration systems, and clear wastewater re-use.

We are expanding our manufacturing capacity by leveraging innovation with multiple ongoing projects, including in connection with the expansion of our state-of-the-art facilities in Ohio and North Carolina that are expected to bring hundreds of jobs to their surrounding communities. Our ongoing manufacturing apprenticeship programs at these sites are expanding opportunities for skilled individuals without a bachelor's degree and increasing our access to talent. (For more information, see the "Human Capital Resources" section below.)

![LOGO](g13946g79g79.jpg)

**Following the announcement of a $1 billion expansion of our North Carolina facilities in December 2024, in 2025, we continued to expand our U.S. manufacturing network, announcing additional investments of $900 million in Ohio and $650 million in Puerto Rico to support increased drug production and the integration of innovative advanced technologies throughout our operations. This expansion reinforces our long-standing commitment to innovation, is designed to enhance the resilience and flexibility of our global supply network, and is expected to create several hundred jobs, including new highly skilled manufacturing jobs.** 

We are also implementing innovative manufacturing processes that are designed to significantly increase our yields. By increasing yields, these innovative process developments greatly enhance our productivity and efficiencies.

Sustainable Value Chain. Our footprint and focus on sustainability extend beyond our own employees and facilities. As part of our 2027 environmental sustainability plan, we are progressing a SBTi-approved Scope 3 supplier engagement target to engage with 73% of our suppliers (by spend in key categories) to support their adoption of science-based carbon emission reduction targets.

#### Responsibility to Our Patients and Communities
Improving Patient Access to Medicines. Through patient assistance and direct-to-patient programs, expanded access to investigational therapies, donations, and other initiatives, Amgen has developed support programs for eligible patients around the world as they seek to obtain the medicines they need.

The Amgen Safety Net Foundation (ASNF), a separate legal entity entirely funded by Amgen, supports eligible patients in the U.S. who might go without important medicines because of financial limitations by providing qualifying Amgen medicines at no cost. Since 2001, ASNF has provided approximately $19 billion in commercial value of Amgen's medicines at no cost to uninsured or underinsured patients.<sup>(</sup><sup>1)</sup> Further, we are making select medicines available directly to U.S. patients at discounted prices through our AmgenNow program.

Over the last five years, Amgen has also donated approximately $483 million worth of Amgen medicines<sup>(1)</sup> for distribution globally via leading non-governmental organizations, including to patients in 12 low- and middle-income countries in 2025. These medicines supplement local healthcare system needs and are also supplied to countries in response to humanitarian crises.

We continue to offer and implement value-based contracts in an effort to help improve patient access to medicines and offer stakeholders greater budget predictability.

Improving Health Outcomes. In developing our medicines, we are working to ensure that clinical trial participants reflect the patient populations impacted by the serious illnesses that we seek to treat. In 2025, we provided the U.S. Food and Drug Administration with activity plans we expect to use to better reflect real-world patient populations for our registrational Phase 2 and Phase 3 clinical studies. We are also focused on facilitating health education and engaging with local community support systems to reach such patients.

Responsible Sourcing. We actively engage with a variety of suppliers. By providing mentorship and education, we are supporting economic development efforts to add

jobs, advance entrepreneurship, and procure goods and services at competitive prices, while creating a broader pool of eligible suppliers for Amgen and other large companies. All our employees are guided by the Amgen Values and global Code of Conduct and, similarly, we request that our suppliers conduct their businesses in alignment with our mission and values.

Our supplier sustainability program focuses on quality, cost, and reliability, as well as on ethical and environmental considerations. Our Supplier Code of Conduct formalizes the expectations that we have of our suppliers, and we routinely monitor and measure the performance of select suppliers.

Science Education. The Amgen Foundation seeks to advance excellence in science education to inspire the next generation of innovators and invest in strengthening communities where our employees live and work.

Since its inception in 1990, the Amgen Foundation has committed $500 million to non-profit organizations around the world that reflect our values and complement Amgen's dedication to impacting lives in inspiring and innovative ways.

&nbsp;&nbsp;&nbsp;&nbsp;• Launched in 2020, LabXchange, developed at Harvard University with support from the Amgen Foundation, is a free online science education platform that offers personalized instruction, virtual lab simulations, and resources from science-based organizations. As of the end of 2025, LabXchange has reached over 68 million people across the globe.

&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, the Amgen Biotech Experience (ABE), a hands-on laboratory initiative that empowers teachers to bring biotechnology labs into high school classrooms across Amgen communities, reached nearly 99,000 students and over 1,600 teachers, operating across 27 sites in 16 countries.

&nbsp;&nbsp;&nbsp;&nbsp;• The Amgen Foundation is a long-time biology content partner of Khan Academy, a leading online learning platform. Since 2015, the Amgen Foundation has awarded Khan Academy over $10 million in support, helping to bring Khan Academy's biology resources to millions of learners and educators around the world.

&nbsp;&nbsp;&nbsp;&nbsp;• The Amgen Scholars Program makes it possible for undergraduate students around the globe to engage in cutting-edge research experiences at some of the world's premier research universities and institutions and learn more about biotechnology and drug discovery. Since its inception 20 years ago, the program has hosted over 5,800 students and, in 2025, the Amgen Foundation announced a new funding commitment to support an additional 500 undergraduate research experiences over the next two years.

Corporate Governance

Our Community. The Amgen Foundation supports local, regional, and international nonprofit organizations that are making a lasting and meaningful impact in our communities, including those that align with our strategy of strengthening science education.

**Employees regularly participate in Amgen's culture of giving back by contributing their time, talents, and financial support. In 2025, Amgen employees volunteered over 24,000 hours. On Giving Tuesday, Amgen staff, together with the Amgen Foundation's matching support, raised over $5 million for more than 2,000 nonprofit organizations.** 

The Amgen Foundation also provides programs and resources to empower individual Amgen staff in their charitable activities in our community, including (for staff in the U.S. and Puerto Rico) through a matching gifts program and by providing service grants to non-profit organizations where our employees volunteer. Additionally, the Amgen Foundation and Amgen's local affiliates provide disaster relief grants to non-profit organizations providing humanitarian assistance in response to catastrophic events and natural disasters.

**Amgen and the Amgen Foundation donated $10 million in disaster relief for those impacted by the January 2025 Southern California wildfires. The Amgen Foundation also matched employee donations toward disaster relief, continuing its commitment to supporting our communities during times of need.** 

#### Human Capital Resources
Our Board has a key role in the oversight of our culture, setting the tone at the top, and holding management accountable for maintaining high ethical standards. The Board believes that human capital resources management, including our talent strategy and organizational culture, are important to our success. The Compensation Committee assists the Board in providing oversight of our human capital resources, including labor and employment, talent strategy, and our culture. We conduct regular employee engagement assessments that gather feedback on a wide range of topics (including flexible work environments, career development, and maintaining a culture of compliance), and the results of these surveys are discussed with our workforce and the Board. Our engagement scores were above general market benchmarks in 2025. Reflecting our staff's desire to retain a flexible approach to work, we offer a flexible workspace initiative that enables many employees to work together with their manager to determine the location that best enables their work at hand, supporting virtual work as well as working in person.

Amgen places significant value on fostering and enabling growth of staff, both personally and professionally, and we aim to provide a safe, healthy, and innovative work environment for our staff.

Our Social Architecture. Since Amgen's founding in 1980, our employees have directed their intelligence and enthusiasm toward our mission to serve patients. This mission, our aspiration to be the world's best human therapeutics company, our strategy, our well-defined set of Amgen Values, and our clear leadership attributes form the "social architecture" that defines our unique culture. We believe that this social architecture has been a key enabler of Amgen's worldwide growth from an early pioneer in the biotech industry to a leading innovator.

Our Culture and Leadership. We also believe that a culture where our staff members feel valued and connected contributes to our success and fosters collaboration, productivity, and innovation as we execute on our mission to serve patients. Consistent with the Amgen Values, we are focused on strengthening and supporting our culture by recruiting, developing, and retaining a strong and engaged workforce informed by the varied experiences represented.

Our executive leadership is responsible for overseeing our workforce strategy and we are dedicated to supporting our managers in upholding and strengthening our values-driven culture. In our effort to attract and retain the best talent, we seek out and support talent across the globe, including by offering a variety of learning resources and data analytics tools that guide our staff and leadership in creating and maintaining this culture.

Our hiring practices also consider, as appropriate, a skills-based hiring approach. For example, our in-house apprenticeship program for the Manufacturing and Amgen Technology and Medical Organizations (ATMOS) functions in the U.S. is designed with the goal of hiring and upskilling talent without a four-year college degree by combining formal learning with classroom-based and on-the-job training as well as mentorship opportunities. After successful completion of the program, apprentices are provided opportunities to transition to full-time roles at Amgen. Multiple cohorts are underway across various sites, including an apprenticeship program at our newest cutting-edge drug substance facility in North Carolina that was launched in 2025.

#### Through our apprenticeship program and other skills-based approaches to hiring, we seek to access a larger pool of highly motivated and productive talent.
Attracting and Developing Talent. We recognize the importance of attracting, motivating, developing, and retaining top talent and skilled staff. We compensate our

Corporate Governance

employees based on their roles, experience, and performance, provide wellness and work-life resources, as well as support employees in giving back and volunteering in their local communities. To support the development of our staff, we provide a variety of programs, including leadership development programs, classroom-based and virtual instructor-led courses, and self-paced learning options as well as mentoring, networking, and coaching opportunities.

In 2025, we invested in general upskilling for our staff on skills for the future, including topics such as AI. We also maintain a talent marketplace that enables staff to contribute to work beyond their core responsibilities, providing opportunities to broaden professional networks within the Company, support organizational priorities, and develop additional skills.

Our Approach to Benefits. Our benefit programs are generally broad-based, promote health and overall well-being, and emphasize saving for retirement. Amgen offers top-tier benefits for full- and part-time employees, including, in the U.S. and Puerto Rico, on-site childcare at certain of our facilities, adoption assistance, resources for elder care and behavioral health, and paid parental leave for all Amgen employees who have or adopt, or become a foster parent or legal guardian for, a child. Globally, comparable benefit programs are offered with the same health and well-being goals, while also designed to comply with local statutory requirements. (For more information, please see Part I, Item 1. Business—*Human Capital Resources* to our Annual Report on Form 10-K for the year ended December 31, 2025.)

Compensation Committee Processes and Procedures for Considering and Determining Executive Compensation in 2025

Compensation Committee Determination of Compensation. The Compensation Committee reviews and approves the Company's prospective performance goals and objectives and evaluates the CEO's performance for the previous year in light of the Company performance goals and objectives established for the prior year. The Compensation Committee evaluates the performance of the CEO within the context of the financial and operational performance of the Company, considers competitive market data, and establishes the CEO's compensation based on this evaluation as well as compensation for each executive officer.

Values and Components. The values of each component of total compensation (base salary, target annual cash incentive awards, and equity awards) for the current year, as well as total annual compensation for the prior year (including the value of equity holdings, potential change of control payments, and vested benefits under our Retirement and Savings Plan, Supplemental Retirement Plan, and Nonqualified Deferred Compensation Plan as of the end of the last fiscal year) are considered. Final determinations regarding our CEO's performance and compensation are made during an executive session of the Compensation Committee and are reported to and reviewed by the Board in an independent directors' session.

Executive Officers. Our Compensation Committee determines compensation for the executive officers (other than the CEO) based, in part, on the recommendations of our CEO regarding base salary, annual cash incentive awards, and equity awards. In determining compensation recommendations for each Named Executive Officer, or NEO, our CEO reviews comparative peer group data, as well as the performance of the executive. FW Cook, an independent compensation consultant to the Committee, also assists the Compensation Committee in its review and determination of executive compensation.

Executive Sessions. Each Compensation Committee meeting includes adequate time for executive session and the Compensation Committee meets in executive session on a regular basis with no members of management present (unless otherwise requested by the Compensation Committee).

Delegation of Authority. The Compensation Committee has authority to delegate any of its functions to a subcommittee of one or more Board members and/or officers, and its responsibilities with respect to incentive compensation, equity compensation, deferred compensation, and employee pension and welfare

benefit plans to our officers and employees, in each case consistent with applicable law. No delegation of authority with respect to compensation of our executive officers was made in 2025.

Independent Compensation Consultant. The Compensation Committee engaged FW Cook to provide advice regarding executive compensation and executive compensation trends and developments, compensation designs, and equity compensation practices, market data as requested, and opinions on the appropriateness and competitiveness of our executive compensation programs relative to market practice. In 2025, FW Cook's services included providing the Compensation Committee with reports and analysis regarding CEO compensation, peer group company review and compensation risk assessment, and advice on executive compensation trends and our equity usage. FW Cook reports directly to the Compensation Committee and attended regularly scheduled meetings of the Compensation Committee (including meeting in executive session with the Compensation Committee, as requested). Each year, the Compensation Committee reviews the independence of FW Cook and whether any conflicts of interest exist. After review and consultation with FW Cook, the Compensation Committee has determined that FW Cook is independent and there is no conflict of interest resulting from retaining FW Cook currently or during the year ended December 31, 2025. In performing its analysis, the Compensation Committee considers the factors set forth in the SEC rules and The NASDAQ Stock Market listing standards.

Compensation Risk Management. In cooperation with management, FW Cook assesses the potential risks arising from our compensation policies and practices as discussed more fully below.

Peer Group Review. In setting executive compensation, the Compensation Committee compares the Company's pay levels and programs to those available for the Company's peer group for executive talent and uses this comparative data as a guide in its review and determination of compensation. Our Compensation Committee annually considers and selects an appropriate peer group (consisting of biotechnology and pharmaceutical companies), based, in part, on the recommendations of FW Cook, and, for each NEO, the Compensation Committee reviews the compensation levels and practices of our peer group, which for our NEOs, other than the CEO, are based on reports prepared by management from information contained in compensation surveys and proxy statements, as available. FW Cook provides the Compensation Committee with market data, an annual report on the compensation levels and practices of our peer group, and compensation recommendations for the CEO position.

Compensation Risk Management

Annual Risk Management Assessment. On an annual basis, management, working with FW Cook, the Compensation Committee's independent compensation consultant, conducts an assessment of the Company's compensation policies and practices for all staff members generally, and for staff members, including our field sales force, who participate in our sales incentive compensation program, for material risk to the Company.

Results of Risk Management Assessment. The results of this assessment are reviewed and discussed with the Compensation Committee. Based on this assessment, review, and discussion, we believe that, through a combination of risk-mitigating features and incentives guided by relevant market practices and our Company performance goals, our compensation policies and practices do not present risks that are reasonably likely to have a material adverse effect on us.

Factors That Discourage Excessive Risk-Taking. In evaluating our compensation policies and practices, a number of factors were identified which the Company, the Compensation Committee, and its independent consultant believe discourage excessive risk-taking, including:

&nbsp;&nbsp;&nbsp;&nbsp;• Mix of Incentives and Metrics. Our compensation programs consist of a mix of incentives and metrics (financial and operational) that are tied to varying performance periods and are designed to balance our need to drive our current performance with the need to position the Company for long-term success.

&nbsp;&nbsp;&nbsp;&nbsp;• Companywide Results. Companywide results are the most important factor in determining the amount of an annual cash incentive award for staff members generally.

&nbsp;&nbsp;&nbsp;&nbsp;• Emphasis on Long-Term Performance. We cap payouts under our annual incentive and three-year performance award programs and make long-term incentive (LTI) equity awards a component of compensation for nearly all our full-time staff members. In particular, the CEO's and the other named executive officers' compensation is designed so that the largest component of their compensation is in LTI equity awards to ensure that a significant portion of their compensation is associated with long-term, rather than short-term, outcomes, which aligns these individuals' interests with those of our stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• Equity Award Grant Practices. We employ appropriate practices with respect to equity awards: we do not award mega-grants, discounted stock options, or immediately vested equity to staff members; our equity grants generally vest over four years, which emphasizes the long-term performance focus of our LTI equity award program and enhances retention; and we have grant guidelines that generally limit the grant date for our equity grants to the date which is two business days after the date of release of our quarterly or annual earnings.

&nbsp;&nbsp;&nbsp;&nbsp;• Stock Ownership and Retention Guidelines. We have stock ownership guidelines for vice presidents and above that require significant investment by these individuals in our Common Stock. We require that each officer who has not met his or her required ownership guidelines hold shares of our Common Stock acquired through the vesting of restricted stock units, the payout of performance units, and the exercise of stock options (net of shares retained by us to satisfy associated tax withholding requirements and exercise price amounts) until such officer has reached his or her required stock ownership level.

&nbsp;&nbsp;&nbsp;&nbsp;• Comprehensive Performance Evaluations. Our Company values and leadership behaviors are an integral part of the performance assessments of our staff members and are particularly emphasized in our assessment tools at higher positions. These evaluations serve as an important information tool and basis for compensation decisions.

&nbsp;&nbsp;&nbsp;&nbsp;• Clawback Policy. Our Compensation committee has adopted a recovery of erroneously awarded compensation policy<sup>(1)</sup> that requires the Company, subject to the limited impracticability exceptions permitted by the NASDAQ listing standards, to recapture from our Section 16 officers, including our NEOs, incentive-based compensation, including annual cash incentive awards and performance units, granted, earned, or vested wholly, or in part, upon the attainment of any financial reporting measure that is subject of a financial restatement with such clawback to occur without regard to fraud or misconduct on the part of the executive.

<sup>(1)</sup> Our clawback policy is available on our website at *https://wwwext.amgen.com/about/how-we-operate/corporate-governance/amgen-policy-on-recovery-of-erroneously-awarded-compensation* and incorporated by reference as Exhibit 97 to our Annual Report on Form 10-K for the year ended December 31, 2025. Reference to our website is not intended to function as a hyperlink and the information contained on our website is not intended to be part of this proxy statement. 

ï *2026 Proxy Statement*43

##### [**Table of Contents**](#toc)
Corporate Governance

&nbsp;&nbsp;&nbsp;&nbsp;• Recoupment. We have recoupment provisions that expressly allow the Compensation Committee or management, as appropriate, to consider employee misconduct that caused serious financial or reputational damage to the Company when determining whether an employee has earned an annual cash incentive award or the amount of any such award.

We maintain an executive officer equity recoupment policy applicable to all equity awards granted after December 31, 2020 that provides the Compensation Committee with the ability to cause the forfeiture and cancellation of unvested equity awards and any unexercised portion of any stock options if an executive officer, including our NEOs, is terminated for engaging in misconduct that caused serious financial or reputational damage to the Company (including, but not limited to, a financial restatement). <br>

&nbsp;&nbsp;&nbsp;&nbsp;• Disclosure. Subject to our clawback and recoupment policies and provisions, we intend to disclose the general circumstances of any application of our clawback or recoupment policies and provisions against any executive officer (current or former) and the aggregate amount of compensation recovered.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• No Hedging or Pledging. Our Insider Trading Policy prohibits pledging or purchasing of our Common Stock on margin<sup>(1)</sup> and hedging the economic risk of our Common Stock (as discussed more fully below).

&nbsp;&nbsp;&nbsp;&nbsp;• Pricing Policies and Controls. Our approach to pricing includes training, standard operating procedures, policies, formal approval mechanisms for price increases and price policy exceptions, and other controls that balance regional and country autonomy with centrally managed price discipline and address Most-Favored-Nations (MFN) considerations, as well as regular auditing, monitoring, and assurance processes. Our Board, with the assistance of the Compliance Committee, has a key role in the oversight of pricing risk and regularly receives presentations from management on global drug pricing practices and trends, including MFN developments and risks.

&nbsp;&nbsp;&nbsp;&nbsp;• Mandatory Global Code of Conduct Compliance Training. We require training on our global Code of Conduct and other policies that educate our staff members on ethical business conduct, the consequences of taking inappropriate actions, and where to escalate concerns, including providing the option of doing so anonymously (except in those few countries where anonymity is not allowed).

Prohibition on Hedging

Under our global Insider Trading Policy<sup>(2)</sup>, all our Board members and staff members, including our NEOs, consultants, contract workers, secondees, and temporary staff worldwide are considered "Covered Persons." It is against the Insider Trading Policy for Covered Persons to directly or indirectly participate in transactions involving trading activities in our securities that, by their nature, are aggressive or speculative, or may give rise to an appearance of impropriety. Covered Persons may not:

&nbsp;&nbsp;&nbsp;&nbsp;• Engage in short sales (sales of stock that the seller does not own or a sale that is completed by delivery of borrowed stock) with respect to our securities;

&nbsp;&nbsp;&nbsp;&nbsp;• Engage in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Amgen stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• Purchase or pledge Amgen stock on margin or as collateral to secure a loan or other obligation<sup>(1)</sup>; or

&nbsp;&nbsp;&nbsp;&nbsp;• Enter into any derivative or similar transactions with respect to our securities.

Examples of prohibited derivative transactions include, but are not limited to, purchases or sales of puts and calls (whether written or purchased or sold), options (whether "covered" or not), forward contracts, including, but not limited to, prepaid variable forward contracts, put and call "collars" ("European" or "American"), "equity" or "performance" swap or exchange agreements, or any similar agreements or arrangements however denominated, in our securities.

<sup>(1)</sup> With the exception of the use of a margin account to purchase our common stock in connection with the exercise of Amgen-granted stock options (i.e., "cashless exercises").

<sup>(2)</sup> A copy of our Insider Trading Policy was incorporated by reference as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

<br> Item 2 — Advisory Vote to Approve Our Executive Compensation<br>

## Item 2

## Advisory Vote to Approve Our Executive Compensation
This advisory stockholder vote, commonly known as "Say on Pay," gives you, as a stockholder, the opportunity to endorse or not endorse our executive pay program and policies. Accordingly, as required by Section 14A of the Securities and Exchange Act of 1934, or the Exchange Act, as amended, you are being asked to cast an advisory vote on the compensation of our Named Executive Officers, or NEOs, as disclosed in the Compensation Discussion and Analysis (pages 46 through 81) and related compensation tables and the narrative in this proxy statement (pages 83 through 100). We urge stockholders to read the Compensation Discussion and Analysis section of this proxy statement, as well as the related tables and disclosures for a more complete understanding of how our executive compensation program operates.

Our Board of Directors, or Board, believes that the 2025 compensation of our NEOs was appropriate, our current executive compensation program aligns the interests of our executives with those of our stockholders, and compensation outcomes are primarily based on the performance of our Company. We intend that our compensation programs reward actions and outcomes that are consistent with the sound operation of our Company, advance our strategy, and are aligned with the creation of long-term stockholder value.

**For these reasons and as discussed more fully in the Compensation Discussion and Analysis, the Board recommends that stockholders vote "FOR" the following resolution:**

"Resolved, that the stockholders approve, on an advisory basis, the compensation paid to the Company's Named Executive Officers, as disclosed pursuant to Securities and Exchange Commission rules in the Compensation Discussion and Analysis, the compensation tables and the accompanying narrative disclosure of this proxy statement."

Although this vote is advisory and is not binding on the Board, our Compensation and Management Development Committee values the opinions expressed by our stockholders and will consider the outcome of the vote when making future executive compensation decisions.

We currently conduct annual advisory votes on executive compensation, and we expect to conduct the next advisory vote on executive compensation at our 2027 annual meeting of stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br> THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE ADVISORY RESOLUTION TO APPROVE THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS.<br>

Our Strategy

Our strategy is the integrated set of actions we take to improve our competitive position in the industry. The focus is inherently long-term in nature. Successful strategy is iterative and requires ongoing resource reallocation across the short-, medium-, and long-term.

#### How Our Board Oversees Our Strategy
Our Board of Directors, or Board, possesses a deep and broad set of skills and experiences that facilitate strong oversight of our strategic direction. Our Board engages in regular reviews of our strategy throughout the year and dedicates one meeting per year to a comprehensive review of our strategy and goals for the business for the

short-, medium-, and long-term. It also reviews and discusses long-term trends to inform short-term decisions. The Company's management is then charged with implementing the business strategy as informed by the Board's review.

#### Our Mission and Therapeutic Areas
Our mission is to serve patients and we do so by developing innovative medicines that have a significant impact on serious illness. Our business is organized across

four therapeutic areas: general medicine, oncology, inflammation, and rare disease. Our biosimilars business is integrated into these therapeutic areas.

Compensation Discussion and Analysis

Aligning Pay With Performance

A substantial majority of each NEO's compensation is at risk and earned based on our execution of our strategy and performance. Our annual cash and long-term equity incentive programs promote focus on activities supporting the execution of our strategic priorities as well as near- and long-term stockholder value creation with compensation earned based on our financial, operating, and stock price performance.

#### Our Executive Compensation Objectives
Our executive compensation program is designed to achieve the following objectives:

&nbsp;&nbsp;&nbsp;&nbsp;• **Pay for performance in a manner that strongly aligns with stockholder interests** by rewarding both our short- and long-term performance.

&nbsp;&nbsp;&nbsp;&nbsp;• **Drive our business strategy** by positioning our staff to execute on our strategic priorities in the near- and

longer-term with a mix of incentives and targets (financial and operational) that are tied to near- and long-term performance periods and activities.

&nbsp;&nbsp;&nbsp;&nbsp;• **Attract, motivate, and retain the highest level of talent** by providing competitive compensation, consistent with their roles and responsibilities, our success, and their contributions to this success.

&nbsp;&nbsp;&nbsp;&nbsp;• **Mitigate compensation risk** by maintaining pay practices that reward actions and outcomes consistent with the sound operation of our Company and with the creation of long-term stockholder value.

&nbsp;&nbsp;&nbsp;&nbsp;• **Consider all Amgen staff members** in the design of our executive compensation program to ensure a consistent approach that encourages and rewards all staff members who contribute to our success.

Execution of Our Strategic Priorities

#### Our 2025 Performance
We delivered strong performance and robust financial results in 2025 and executed well on our strategic priorities, including rapidly advancing our innovative pipeline and expanding our manufacturing capacity. We executed on our capital allocation priorities, including investing substantially in our late-stage clinical programs and our innovative manufacturing facilities (including those in Ohio and North Carolina) and process development capabilities. We accomplished these objectives while advancing our other strategic priorities and our sustainability efforts.

1. We delivered strong financial performance.

a. Revenues and b. non-GAAP net income - 30%

&nbsp;&nbsp;&nbsp;&nbsp;weighting each

At the beginning of the first quarter of 2025, we shared our initial full-year 2025 outlook in connection with the release of our 2024 financial results, including a projected revenue range of $34.3 to $35.7 billion and a projected non-GAAP earnings per share, or EPS<sup>(1)</sup>, range of $20.00 to $21.20. Shortly thereafter, the Compensation Committee established 2025 financial performance goals, with a revenue goal target that was slightly above the midpoint of this revenue range, and a non-GAAP net income goal that was generally correlated to the midpoint of this non-GAAP EPS range. These financial performance targets were also above our actual 2024 revenue and non-GAAP net income performance.

As a result of the focused execution by our executive leaders and the efforts of our entire Company, while growing our investment in research and development significantly to support the progression of our innovative pipeline, our 2025 revenues of $36.751 billion and non-GAAP net income of $11.837 billion were each significantly above target, resulting in 155.3% of target achieved for our revenue goal and 132.9% of target achieved for our non-GAAP net income goal, for a weighted payout of 86.5% of target incentive opportunity. Based on this strong financial performance and robust execution of our operational and annual priorities goals, performance under our 2025 Company performance goals resulted in achievement and payout under our annual cash incentive program at 136.0% of target bonus opportunity.

2. We progressed our pipeline.<sup>(2)</sup>

In 2025, we progressed our strong and broad pipeline.

a. Early pipeline - 10% weighting

We advanced our early pipeline in 2025, including:

&nbsp;&nbsp;&nbsp;&nbsp;• We progressed: (i) nine new discovery-stage research programs investigating novel targets discovered internally or known targets with a novel therapeutic hypothesis in oncology (for the treatment of bladder and ovarian cancers and acute myeloid leukemia), inflammation (for the treatment of systemic lupus erythematosus, primary sclerosing cholangitis, and myotonic dystrophy), and cardiovascular and metabolic diseases (for the treatment of heart failure, acute myocardial infarction, and hypertrophic cardiomyopathy); (ii) two new innovative therapeutic platforms that enable drug discovery; (iii) two product candidates for the treatment of solid tumors by satisfying regulatory requirements to initiate first-in-human studies; and (iv) three clinically actionable biomarker packages for molecules being studied for the treatment of solid tumors and severe uncontrolled asthma.

3. We delivered on our annual priorities.

&nbsp;&nbsp;&nbsp; <br> Technology and Workforce - 10% weighting<br>

To support our mission to serve patients and our focus on long-term growth, our technology and workforce strategy is an important driver for unlocking new capabilities, enhancing productivity, and accelerating future innovation. In alignment with this focus, our 2025 annual incentive plan included a technology and workforce goal designed to enable Amgen to leverage and accelerate the use of new technologies in a critical period of execution. We exceeded target performance in this area, delivering measurable progress across end-to-end process innovation, technological advancement, and workforce transformation initiatives.

End-to-end process innovation: To further increase the speed, quality, and efficiency of our clinical development processes, we successfully built and validated new systems to collect clinical trial data and manage our clinical trials, and we standardized and streamlined how we run Phase 2 and 3 clinical studies. We also strengthened cross-functional planning by using new technologies to better connect our finance, tax, operations, commercial, and research and development processes to support improved decision-making, efficiency, and visibility into performance across the organization. By the end of 2025, we completed core design and build activities and launched program testing.

Technological advancement: To meaningfully increase the impact of technology at the Company, we established a holistic technology and data governance process to evaluate enterprise data, analytics, artificial intelligence (AI), and machine learning project funding requests.

Workforce transformation: To enhance digital literacy across key groups and enable data-driven decision-making, we conducted AI training for 99% of our staff members at the Vice President-level and above that was designed to increase AI-fluency and reinforce ethical AI and cybersecurity policy compliance. Further, to reimagine and shape the future capabilities necessary for the success of our workforce, we completed nineteen ambition roadmaps and detailed designs across key business functions.

We delivered on our other strategic priorities.

Performance Under Our

Long-Term Incentive Program

Our long-term incentive (LTI) compensation plan is tied directly to our stock performance and key annual operational metrics and aligns with long-term value creation for our stockholders.

80% of our annual LTI equity award grants are performance-based, aligning compensation with long-term value creation for our stockholders. Performance units comprise 50% of our annual LTI equity award grants. The goal design and all measurement targets are established at the beginning of each three-year performance period. For the 2023-2025 performance period, awards were earned based on our performance as measured against rigorous annual targets established at the beginning of the performance period for the equally weighted non-GAAP<sup>(1)</sup> operating measures of EPS growth and return on invested capital, or ROIC, with a three-year Total Shareholder Return, or TSR, modifier of <sup>+</sup>/- 30 percentage points relative to the TSR of the companies in the S&P 500. EPS growth was selected as a measure to drive delivery of shareholder value and the ROIC measure reflects our ongoing focus on remaining operationally disciplined in our management of our capital. At the end of the 2023-2025 performance period, our performance under the two annual operating measure percentages was averaged, resulting in a total operating measures score of 105.6%.

Target TSR performance over the three-year performance period was set at the 50<sup>th</sup> percentile relative to the TSRs of the companies in the S&P 500. For relative TSR performance below the 50<sup>th</sup> percentile, there is a reduction in the total percentage of performance units earned for the performance period. For the 2023-2025 performance period, our TSR performance ranking relative to the TSRs of the companies in the S&P 500 for the three-year performance period was at the 65th percentile of S&P 500 companies and resulted in a positive 18.4 percentage points TSR modifier for a total payout of 124.0% of performance units granted. A detailed depiction of our performance under these operating measures and the resulting calculation is on the next page.

For the 2025-2027 performance period, the Compensation Committee retained the same performance award goal design as that of the 2024-2026 performance period with the non-GAAP operating measures of EPS and ROIC weighted equally in each year measured against targets and goals pre-established at the beginning of the three-year performance period for each year of the performance period. The Compensation Committee

selected non-GAAP EPS to drive delivery of value to stockholders and ROIC to reflect our ongoing focus on remaining operationally disciplined in our management of our capital. The Compensation Committee also retained the TSR modifier of **<sup>+</sup>**/-30 percentage points and the requirement that the TSR modifier cannot exceed target regardless of our relative TSR performance if our absolute TSR over the performance period is less than zero. This requirement ensures a stronger tie to stockholders' interests and investment experience in a challenging market.

---

---

| | |
|:---|:---|
| ✓ | Stock ownership and retention guidelines: We have a six times base salary stock ownership requirement for our Chief Executive Officer. Our Executive Vice Presidents and Senior Vice Presidents have three times and two times base salary stock ownership requirements, respectively. Officers are required to hold shares of our Common Stock acquired through the vesting of restricted stock units, or RSUs, the payout of performance units, or the exercise of stock options until they have reached the required stock ownership level. Compliance with this policy is assessed annually and all executive officers, including our NEOs, who were expected to meet such guidelines by December 31, 2025, were in compliance.  |

---

---

| | |
|:---|:---|
| ✓ | Clawback Policy: Our Compensation Committee has adopted a clawback policy<sup>(1)</sup> that provides for the mandatory recovery from our Section 16 officers, including our NEOs, of erroneously awarded incentive-based executive compensation, including past annual cash incentive awards and performance unit payouts received by our executive officers, granted, earned, or vested, wholly or in part, upon the attainment of any financial reporting measure that is the subject of a financial restatement. The clawback policy is a no-fault policy as it is applicable to all Section 16 officers regardless of any misconduct or negligence.  |

---

✓ Recoupment Provisions for Misconduct: Our recoupment mechanisms include:

---

| | |
|:---|:---|
| ✓ | Cash Incentive Compensation Plan Recoupment Provisions: Recoupment provisions applicable to all staff members that expressly allow the Compensation Committee to determine that annual cash incentive awards are not earned fully, or in part, where such employee has engaged in misconduct that causes serious financial or reputational damage to the Company.  |

---

---

| | |
|:---|:---|
| ✓ | Equity Recoupment Policy: We maintain a policy, applicable to all equity awards granted after December 31, 2020, that provides the Compensation Committee with the ability to cause the forfeiture and cancellation of unvested equity awards and any unexercised portion of any stock options should an executive officer be terminated for engaging in misconduct that caused serious financial or reputational damage to the Company.  |

---

✓ Independent compensation consultant: The Compensation Committee retained and sought advice from Frederic W. Cook & Co., Inc., or FW Cook, to assist the Compensation Committee in its review and determination of executive compensation.

✓ Consider Amgen Values: The Amgen Values<sup>(2)</sup> overlay our Company performance goals and the Compensation Committee assesses each NEO's annual compensation based on compliance with these internal standards.

#### Retaining and Attracting Executive Talent
The Compensation Committee recognizes the unique demands of our industry, including its complex regulatory and reimbursement environment, and the challenges of running an enterprise focused on the discovery, development, manufacture, and commercialization of biologic and small molecule medicines to address serious illness. The Compensation Committee believes that these unique demands require executive talent that has significant industry experience as well as, for certain key functions, specific scientific expertise to oversee research and development activities and the complex manufacturing requirements of biologic and small molecule products. Further, the Compensation Committee believes that these very particular skills and capabilities limit the pool of talent from which we can recruit and also cause our employees to be highly valued and sought after in our industry. These factors inform the compensation decisions of the Compensation Committee.

#### Use of Independent Compensation Committee Consultant
For 2025, to assist the Compensation Committee in its review and determination of executive compensation, the Compensation Committee retained and directed the nature of the activity between FW Cook, an independent consultant, and management undertaking the responsibilities previously described in "How Compensation Decisions Are Made For Our Named Executive Officers." For 2025, FW Cook provided advice, consultation and reports regarding regulatory updates, selection of our peer group, CEO realized and realizable compensation, market competitiveness of our CEO compensation, and equity incentive programs and trends. The Company did not engage FW Cook for any other services in 2025.

| &nbsp;&nbsp; Amgen | $148 billion | $31 billion |
| &nbsp;&nbsp; Relative Peer Group Position | 2<sup>nd</sup> quartile | 1<sup>st</sup> quartile |

---

<sup>(a)</sup> Represents the 12-month average market capitalization as of June 30, 2024.

<sup>(b)</sup> Represents revenues for the trailing four quarters ending March 31, 2024, except Sanofi S.A., which is for the trailing four quarters ending December 31, 2023, as provided by the Standard and Poor's Capital IQ database, and includes pro forma results of a combined Amgen Inc. and Horizon Therapeutics plc (Horizon) entity through March 31, 2024, as if the Company's acquisition of Horizon had occurred on April 1, 2023. 

#### Peer Group Data Sources
Our primary data source for evaluating all elements of compensation for our CEO is data compiled by FW Cook from the SEC filings of our peer group, including for the 25<sup>th</sup>, 50<sup>th</sup>, and 75<sup>th</sup> percentiles of the specific compensation elements paid to peer group CEOs. For 2025 compensation decisions for our executives, other than the CEO, management employs additional published survey sources to provide a robust and comprehensive data set. As in prior years, our primary data sources for evaluating all elements of compensation for our executives, other than our CEO, included available data from peer group proxy statement filings, the Willis Tower Watson Pharmaceutical Human Resources Association Survey, the Willis Towers Watson BioPharma and Life Sciences Survey, and the Radford McLagan Compensation Database.

#### Our Use of Peer Group Data
In any given year, our Compensation Committee, with advice from FW Cook, may depart from the benchmarking data to account for structural differences in our organization versus those of our peer group, the

strategic importance of certain roles to our business, and internal equity. Factors such as an individual's experience, performance and tenure, as well as the size, scope, complexity and impact of the role, and market demand for the position can also come into consideration. For example, the Executive Vice President and Chief Technology Officer role held by Dr. Reese is not well-matched in benchmarking data or peer group proxy statements, given the unique scope and complexity of this role, which includes responsibilities for accelerating the use of technology and artificial intelligence across the organization as well as for the Global Medical function. Due to this lack of comparability, the compensation for our Executive Vice President and Chief Technology Officer is determined in relation to the compensation decisions made for our other Executive Vice President roles.

Based on this data (to the extent applicable), the Compensation Committee is presented with a comparison of each NEO on a position or pay rank basis, with information of each element of compensation for such NEO at the 25<sup>th</sup>, 50<sup>th</sup> (the Market Median), and 75<sup>th</sup> percentile of the peer group (together, Market Comparison Data). Consistent with generally accepted

ï *2026 Proxy Statement*63

##### [**Table of Contents**](#toc)
Compensation Discussion and Analysis

practice, all survey data is aged forward to March 1, 2025 using an update factor of 3.3%, our base salary market rate increase for 2025, to represent projected market movement across all compensation elements.

Market Comparison Data is determined for our CEO and our other NEOs based on the most recently disclosed compensation of the Company's peers (with a focus on U.S. companies) at the time compensation decisions are made and is considered by the Compensation Committee as a reference point to inform compensation decisions made in March of each year as described below.

#### 2026 Peer Group Companies
In July 2025, FW Cook reviewed our peer group with the Compensation Committee to determine whether the peer group remains appropriate for 2026. FW Cook recommended the continued use of the previously established objective criteria for consideration when developing the peer group pool and that continued focus on U.S. peers is appropriate, recognizing that the non-U.S. peers reflect differences in law, stockholder influences, and governance practices. FW Cook further recommended to make no changes to the peer group for 2026 except to remove Biogen Inc, as this company no longer fully satisfies the objective criteria for inclusion previously described. Based, in part, on these recommendations from FW Cook, as well as a review of the objective criteria, the Compensation Committee removed Biogen Inc. from the current peer group and determined that this peer group, composed of 14 companies (nine of which are based in the U.S.) is appropriate for 2026 executive compensation benchmarking.

Elements of Compensation and Specific Compensation Decisions

Described below are our three primary elements of executive compensation in order of magnitude: LTI equity awards; annual cash incentive awards; and base salaries.

Long-Term Incentive Equity Awards

Our compensation program aims to achieve the appropriate balance of compensation elements relative to the responsibilities of our staff members, with the result that the largest proportion of compensation for our CEO and the other NEOs is in LTI equity awards that are risk-based and closely aligned with the creation of long-term stockholder value. For 2025, equity-based compensation represents 79% of our CEO's target compensation and 67% of target compensation for our other NEOs on average, and 50% of annual equity awards are in long-term performance units. In addition, while being mindful of stockholder dilution (see below), we also grant LTI equity awards each year to nearly all of our staff members worldwide to increase staff awareness of how our performance impacts stockholder value. We believe that our practice of granting equity-based compensation broadly has been a significant factor in advancing our strategic priorities by aligning all of our staff members' (including our NEOs') interests with those of our stockholders, rewarding execution of our strategy, fostering long-term focus, and enhancing retention.

#### We Continue to Exercise Discipline in the Grant of Long-Term Incentive Equity Awards—Monitoring Dilution and Annual Equity Usage
Our Compensation Committee balances the use of equity to align staff members with our stockholders while

striving to limit stockholder dilution to that amount which investors would expect to experience with members of our peer group. Following its annual review of the Shareholder Value Transfer (SVT) associated with proposed aggregate LTI equity award grants to ensure that our SVT is aligned with our peer group practices, LTI equity award grant guidelines were established in reference to the practices of our peer group and an annual LTI equity award budget was set at approximately the 50<sup>th</sup> percentile of our peer group. As illustrated below, the resulting dilutive effect of our equity grants has been maintained at a generally consistent level over the past six years.

##### [**Table of Contents**](#toc)
Compensation Discussion and Analysis

#### Long-Term Incentive Equity Award Mix
As part of its annual evaluation of our LTI equity award practices, the Compensation Committee reviewed our LTI equity award mix with FW Cook and elected to maintain the previous year's LTI equity award allocation for 2025 given its pay-for-performance alignment. As such, 80% of our annual equity award value continued to be delivered as performance-based LTI equity awards consisting of performance units (50%) and stock options (30%). Time-vested RSUs, designed to foster retention, comprise the remaining 20% of equity value. Stock options and RSUs generally vest over four years to support the longer-term performance emphasis of our LTI equity award program and enhance retention. For more information on our equity award vesting schedule, please see the "Minimum Vesting Requirements" section below.

#### Value of 2025 Annual Long-Term Incentive Equity Awards
Based on a review of Company and executive performance, Market Comparison Data, and FW Cook and management's recommendations, in March 2025 the Compensation Committee determined to grant the following annual LTI equity award grant values to our CEO and the other NEOs, with an effective grant date of May 6, 2025, the date which was two business days after the date of release of our first quarter 2025 earnings results in accordance with our equity grant policy.

<sup>(1)</sup> The 2025-2027 performance period runs from January 1, 2025 through December 31, 2027.

In March 2025, based on the Compensation Committee's review of Market Comparison Data, the Committee approved an annual LTI equity award for Mr. Bradway at the same value ($18.0 million) as that of 2024 to recognize his continued successful leadership and execution of the Company's strategic priorities as well as his tenure in the CEO role. The Compensation Committee also approved annual LTI equity awards for Mr. Gordon ($5.3 million) and Dr. Reese ($4.8 million) at the same values as those of 2024 in recognition of their continued successful leadership of their respective functions, scope of responsibilities of their respective roles, and execution of activities in support of the long-term growth of the Company. For Dr. Bradner, the Compensation Committee approved an annual LTI equity award grant value increase of $500,000 to recognize his successful

leadership of the Research and Development organization during a period of significant pipeline activity and advancement as well as the scope and criticality of his role. In establishing Mr. Griffith's compensation for 2025, the Compensation Committee considered his experience and the strategic importance of his expanded operational responsibilities, including Mr. Griffith's leadership of significant enterprise-wide technology and system implementation initiatives, and approved an increase in annual LTI equity grant value for Mr. Griffith (from $4.8 million to $5.3 million). The Compensation Committee concluded that these annual LTI equity award values were appropriate because they provide compensation that is substantially "at risk," performance-based, focused on the longer-term, and aligned with stockholder interests.

Performance Award Program 2023-2025 Performance Period Performance Units Earned

For the last operating year of our 2023-2025 performance period, our 2025 non-GAAP<sup>(1)</sup> EPS performance earned 110.7% of target and 2025 ROIC performance earned 102.1% of target, resulting in 2025 performance of 106.4% of target for these non-GAAP operating measures. Our performance with respect to our combined non-GAAP operating measures resulted in achievement against target of 113.8% for 2023, 96.7% for 2024, and 106.4% for 2025. These annual operating measure percentage calculations were then averaged for a total operating measures score of 105.6% for this three-year performance period. Based on our TSR ranking of the 65<sup>th</sup> percentile relative to the TSRs of the companies in the S&P 500, the total operating measures score of 105.6% was increased by 18.4 percentage points, resulting in a payout of 124.0% of target performance units granted. Each earned performance unit converted to one share of Common Stock upon the payout date of March 16, 2026. For the 2023-2025 performance period, this payout percentage resulted in the following number of shares of Common Stock being earned. (For additional information on the specific targets and actual performance and calculation of amounts earned, see the detailed description of the 2023-2025 performance period previously discussed on page 56.)

All operating measures and goals were established at the beginning of the three-year performance period.

The Compensation Committee constructed the goal design for the 2024-2026 performance period (January 1, 2024 to December 31, 2026) with the same two operating measures as that of the Company's other active performance periods of non-GAAP EPS growth and ROIC weighted equally in each year and relative TSR modifier (<sup>+</sup>/-30 percentage points). The TSR modifier cannot exceed target regardless of our relative TSR performance if our absolute TSR over the performance period is less than zero.

Compensation Discussion and Analysis

#### Performance Award Goal Design for the 2026-2028 Performance Period
As part of its regular review and consideration of the performance award program, the Compensation Committee evaluated potential performance award goal designs for the 2026-2028 performance period (January 1, 2026 to December 31, 2028) with input from management and FW Cook at its December 2025 and March 2026 meetings. Based on such evaluations, the Compensation Committee established performance goals for the 2026-2028 performance period to better align with peer group practices and further incentivize delivery of stockholder value. The 2026-2028 performance period goals retain the non-GAAP EPS goal, replace the non-GAAP ROIC goal with a relative TSR goal, and remove relative TSR as a modifier. The relative TSR goal continues to measure our TSR performance relative to the TSRs of the companies in the S&P 500 over the three-year performance period on a cumulative basis. In addition, if our absolute TSR over the three-year performance period is less than zero, payout under the relative TSR goal cannot exceed target, regardless of our relative TSR performance. The non-GAAP EPS and relative TSR performance goals are weighted equally (one-half per measure) with non-GAAP EPS measured against pre-established annual targets for each year of the 2026-2028 performance period. In addition, with the removal of the relative TSR modifier of +/- 30 percentage points, the performance goal payout range was adjusted to 0%-200% (from 30%-170% with a +/- 30% modifier) to maintain the payout opportunity for the 2026-2028 performance period at the overall payout ranges of the Company's other active performance periods. In addition, to improve comparability to other full-value awards, align the number of performance units granted with approved grant values, and provide participants with greater transparency regarding award values, the Compensation Committee modified the method for converting grant values into target performance units to use the closing stock price on the grant date rather than the grant date fair value used for accounting purposes.

#### Dividend Equivalents
RSUs and performance units have dividend equivalent rights. Such dividend equivalents are payable only when, and to the extent that, the underlying RSUs and performance units, as applicable, are vested, earned, and converted to shares of Common Stock. The dividend equivalents may be paid in stock (with cash paid for fractional shares) or in cash at the Compensation Committee's election. Stock options do not have dividend equivalent rights.

#### Minimum Vesting Requirements
Mindful of stockholder concerns and best practices, our equity incentive plan requires that at least 95% of all equity awards, including RSUs, restricted stock, stock options, performance awards, and dividend equivalents granted to staff members (including NEOs) will be subject to a minimum vesting period of no less than one year. Stock option and RSU grants generally vest over four years to emphasize the long-term focus of our LTI equity award program and enhance retention of staff members. After review of market competitive practices, the Compensation Committee determined that, beginning with awards granted on or after April 1, 2025, stock options and RSUs will vest in four equal installments on the first, second, third and fourth anniversaries of the grant date (awards granted prior to April 1, 2025 vest in three approximately equal annual installments on the second, third, and fourth anniversaries of the grant date).

#### Long-Term Incentive Equity Awards Granted to Named Executive Officers in 2026
The Compensation Committee reviewed the LTI equity award grant values proposed to be granted to NEOs in 2026. The Compensation Committee approved an increase in Mr. Bradway's LTI equity award grant value (from $18 million to $20 million) to recognize his continued successful execution against the Company's strategic priorities as well as his experience and tenure in his role, and after review of Market Comparison Data reflecting that Mr. Bradway's total target direct compensation for 2025 was less than the Market Median. The Compensation Committee maintained the LTI equity award grant values for Messrs. Gordon and Griffith ($5.3 million) and Dr. Reese ($4.8 million) to recognize their continued successful leadership of their respective functions and strong execution of activities in support of the long-term growth of the Company. To address changes in Market Comparison Data and recognize Dr. Bradner's successful leadership of our Research and Development team during a period of significant pipeline activity and advancement as well as the scope and criticality of his role to the Company, the Compensation Committee approved an increase in his LTI equity award grant value (from $4.8 to $5.1 million). The Compensation Committee concluded that the LTI equity award values granted were appropriate because they recognize and reward strong execution by our executives with compensation that is substantially at risk, performance-based, and focused on the longer-term.

Compensation Discussion and Analysis

Annual Cash Incentive Awards

#### Executive Incentive Plan
Annual cash incentive awards to our NEOs are generally made under our stockholder-approved Executive Incentive Plan, or EIP, which employs a formula that establishes a maximum award possible for each participant based on our non-GAAP net income<sup>(1)</sup>. For 2025, each of our NEOs was a participant in the EIP. This year, as in the past, actual awards under the EIP are determined by the Compensation Committee using its negative discretion under the EIP, with award determinations based on Company performance against the composite final score of the pre-established 2025 Company performance goals. In evaluating and confirming this approach, the Compensation Committee also considers the contributions of each participant's role to our success during the year.

In March 2025, the Compensation Committee determined the plan design for the Global Management Incentive Plan, or GMIP, and Global Performance Incentive Plan, or GPIP; the 2025 Company performance goals and weightings; the percentages payable for threshold, target, and maximum performance under such goals; the definition of non-GAAP net income<sup>(1)</sup> and the maximum award payable for each EIP participant; and the target annual cash incentive award opportunities for each EIP participant. The maximum award under the EIP continued to be expressed as the EIP non-GAAP net income definition and, consistent with past years, was 0.125% for our CEO and 0.075% for each of the other NEOs.

As discussed previously, both historically and in 2025, the Compensation Committee has paid well below the maximum award permitted under the EIP based on a practice of exercising negative discretion by using the Company performance goals composite final score under our GMIP as applied to the participant's target annual cash incentive award opportunity to determine actual awards.

Target Annual Cash Incentive Award Opportunity

After review of Market Comparison Data and consultation with FW Cook, the Compensation Committee determined that the target annual cash incentive award opportunities for our NEOs would remain the same as those of 2024 (150% of base salary actually paid for the year for our CEO and 100% for each of the other NEOs).

#### 2025 Company Performance Goals
While all of the goals established under our annual cash incentive plan measure single-year performance, taken as a whole, they are intended to positively position us for both near- and long-term success, support our strategic priorities, and create stockholder value. The 2025 Company performance goals approved by the Compensation Committee were based on our February 2025 earnings guidance and 2025 budget at the time of such approval and targets for the financial measures were set higher than actual results under our 2024 annual cash incentive plan.

For the 2025 Company performance goals, in March 2025, management recommended, and the Compensation Committee reviewed and concurred with, the retention of the same performance goal design (Deliver Results (60%), Progress Innovative Pipeline (30%), and Deliver Annual Priorities (10%)) as that of the 2024 Company performance goals. For the Annual Priorities goal, our Compensation Committee approved technology and workforce goals (weighted 10%) for our 2025 Company performance goals focused on driving end-to-end process innovation, technological advancement, and workforce transformation initiatives designed to enable Amgen to leverage and accelerate the use of new technologies in a critical period of execution.

2025 Company Performance Goals and Results

The table below sets forth the goals established, the weighting of each goal, and our actual performance for 2025. Payouts can range from 0% to a maximum of 225% of target annual cash incentive award opportunity for each metric, performance between goals is linearly interpolated, and the final Company Performance Goals Score cannot exceed 225%. For additional discussion regarding our performance, please see "Aligning Pay With Performance" and "Execution of Our Strategic Priorities."

Based on strong financial performance and execution of operational goals and annual priorities, performance under our 2025 Company performance goals resulted in performance achievement and payout at 136.0% of target annual cash incentive award opportunity.

---

For the 2026 Company performance goals, the Compensation Committee maintained the same overall goal design as in 2025. "Technology & Workforce" was retained as an annual priority to continue progressing the organization's technological advancement, end-to-end process innovation, and workforce transformation initiatives, including expanding and executing on the capabilities and governance structures developed in 2025.

The Compensation Committee also reviewed the target incentive award opportunity for each NEO and determined that the previously established target incentive award opportunities remain appropriate and no changes were made to the target incentive award opportunity for any NEO for 2026.

Base Salaries

Generally, in March of each year, the Compensation Committee reviews Market Comparison Data, our performance, market conditions, retention, and other relevant factors, and receives management's, including our CEO's, assessment of the performance of each of the other NEOs, and recommendations regarding any base salary adjustments for them. The Compensation Committee uses our CEO's evaluation of the performance of the NEOs (other than himself), the Compensation Committee's own evaluation of our CEO's performance, information with respect to each NEO's experience and other qualifications, internal pay equity, Market Comparison Data for each available position, and market conditions to determine each NEO's base salary. No increase in base salary is automatic or guaranteed.

In March 2025, the Compensation Committee considered each NEO's base salary against Market Comparison Data, while taking into account the Company's and each NEO's performance, as well as current market conditions. Consistent with the base salary increase made to staff members generally, the Compensation Committee increased the respective base salary for Messrs. Bradway and Gordon and Drs. Reese and Bradner by 3.3%. After considering Mr. Griffith's contributions to the Company, as previously discussed under "Long-Term Incentive Equity Awards—*Value of 2025 Annual Long-Term Incentive Equity Awards*", the Compensation Committee increased his base salary by 9.1%.

#### 2026 Base Salary Adjustments
In March 2026, the Compensation Committee considered each NEO's base salary against Market Comparison Data, while taking into account the Company's and each NEO's performance, as well as current market conditions. The Compensation Committee maintained the same base salary ($1,927,000) for Mr. Bradway as that of 2025, emphasizing the importance of performance-based long-term incentive compensation for Mr. Bradway. The Compensation Committee increased the base salaries of Messrs. Gordon and Griffith and Drs. Bradner and Reese by 3.5%, consistent with the base salary increases for our U.S. staff members.

#### Target Total Direct Compensation
Target total direct compensation, or TDC, is the sum of the NEO's base salary and target annual cash incentive award, which is a multiple of base salary, and target annual long-term incentive award. The Compensation Committee believes that reviewing our NEOs' target total direct compensation and Market Comparison Data, provides a useful check in making compensation decisions. In March 2025, after reviewing target total direct compensation for each NEO compared to the available market data and 2024 TDC, the Compensation

Committee found such target total direct compensation to be appropriate and supportive of the base salary and target annual cash and long-term incentive awards compensation decisions for Mr. Bradway given his sustained performance, strong leadership, and tenure in the CEO role. At the time of the Compensation Committee's approval, the CEO's TDC was approximately at the 75th percentile and, when reviewed at the end of 2025 using updated Market Comparison Data, his TDC approximated the Market Median. In general, the TDC of the other NEOs align within 15% of the Market Median, which the Compensation Committee believes represents a market competitive position. Further, the Compensation Committee determined that the TDC for the other NEOs was appropriate and supportive of the respective base salaries and target annual and long-term incentive awards compensation decisions, given each NEO's successful leadership of their respective functions, scope of responsibilities in their respective roles, and experience. The Compensation Committee also considered Mr. Griffith's contributions to the Company, as previously discussed under "Long-Term Incentive Equity Awards—*Value of 2025 Annual Long-Term Incentive Equity Awards*", when determining his target total direct compensation.

Target Total Direct Compensation

Target total direct compensation as proposed for 2025 is shown in the table below:

Compensation Discussion and Analysis

#### Perquisites
Perquisites are limited in both type and monetary value. The Compensation Committee believes, however, that certain perquisites facilitate the efficient operation of our business, allowing our NEOs to better focus their time, attention, and capabilities on our Company, permit them to be accessible to the business as required, alleviate safety and security concerns, and assist us in recruiting and retaining key executives. The perquisites provided to our NEOs generally include an allowance for personal financial planning services, including tax preparation services (not to exceed $15,000 annually in aggregate), annual physical examinations, Company-paid moving and relocation expenses paid on behalf of newly hired and current executives who agree to relocate to work on the Company's behalf and, in limited instances, personal expenses when on business travel such as guests accompanying NEOs. Certain of our NEOs also have access to a Company car and driver and, subject to the approval of our CEO, the Company aircraft for personal use. Our CEO is encouraged to use our Company aircraft for all of his travel (business and personal) because the Compensation Committee believes that the value to us of making the aircraft available to our CEO, in terms of safety, security, accessibility, and efficiency, is greater than the incremental cost that we incur.

The Compensation Committee regularly reviews our perquisite disclosures and practices. For example, in 2024 and 2025, we conducted an independent third-party assessment of our executive security practices, including those deployed while at work and during business travel, in light of the evolving executive security environment. This assessment considered risks specific to Amgen, benchmarking data, and industry best practices as well as insights from our ongoing monitoring of the evolving security landscape, including proactive engagement with law enforcement agencies and senior leadership. Based on this review, the Compensation Committee approved enhancements to our executive security

program in 2025 that included measures such as cyber and digital security surveillance and enhanced residential security.

No tax gross-up reimbursements are provided to NEOs, except in connection with reimbursement of moving and relocation expenses consistent with our other staff members and our general relocation policy. We believe that providing tax gross-up reimbursements on the applicable moving and relocation expenses paid on behalf of newly hired and current executives who agree to relocate on the Company's behalf is appropriate because it treats these executives in a similar manner as non-executives under our Companywide policy which is designed to incentivize optimal deployment of our human resources in support of the Company's strategy. It also assists in the attraction and retention of the executive talent necessary to compete successfully.

We provide limited home sale loss assistance for Senior Vice Presidents and above in connection with relocations that benefit us and are at our request, and in certain new hire situations. We do not provide tax gross-ups for assistance with loss on sale of a home. Our limited home sale loss assistance serves as an important tool in inducing senior management to fully commit to their new role and relocation.

Repayment Provision. Our Companywide policy includes a repayment provision, to the extent permitted by law, applicable to staff members (including our NEOs) that requires a new staff member hired from outside the Company or staff members who accept an assignment and relocate, to repay us for moving and relocation expenses and any home loss assistance incurred by us in the event that the staff member does not complete the move, resigns, or is discharged for cause within two years of the employment start date or relocation date, as applicable (with a pro-rata repayment in the second year). Further, certain other forms of new hire compensation are also subject to repayment provisions.

Compensation Policies and Practices

#### Clawback and Recoupment
Clawback Policy. We have adopted a recovery of erroneously awarded compensation policy<sup>(1)</sup>, or clawback policy, that requires that the Company, subject to the limited impracticability exceptions

permitted by NASDAQ Stock Market listing standards, recapture from our Section 16 officers, including our NEOs incentive-based compensation, including annual cash incentive awards and performance unit payouts, that were granted, earned, or vested, wholly or in part,

<sup>(1)</sup> Our clawback policy is available on our website at https://wwwext.amgen.com/about/how-we-operate/corporate-governance/amgen-policy-on-recovery-of-erroneously-awarded-compensation and incorporated by reference as Exhibit 97 to our Annual Report on Form 10-K for the year ended December 31, 2025. Reference to our website is not intended to function as a hyperlink and the information contained on our website is not intended to be part of this proxy statement.

##### [**Table of Contents**](#toc)
Compensation Discussion and Analysis

upon the attainment of any financial reporting measure that is the subject of a financial restatement<sup>(1)</sup>, without regard to fraud or misconduct on the part of the executive. Compensation subject to this clawback policy is the gross amount received in excess of that which would have been received based on the restated financials.

Equity Recoupment Policy. We maintain an executive officer equity recoupment policy, applicable to all equity awards granted after December 31, 2020, that provides the Compensation Committee with the ability to cause the forfeiture and cancellation of unvested equity awards and any unexercised portion of stock options in the event an executive officer is terminated for engaging in misconduct that caused serious financial or reputational damage to the Company (including, but not limited to, a financial restatement). If an executive officer is subject to an investigation potentially implicating conduct that could result, or may have resulted, in serious financial or reputational damage to the Company, the Company may freeze access to covered equity awards during the investigation, and such unvested equity awards and unexercised stock options may ultimately be subject to forfeiture and cancellation.

Cash Incentive Award Recoupment. Our cash incentive award programs (EIP, GMIP, and GPIP) expressly allow the Compensation Committee, or management, as appropriate, to consider employee misconduct that caused serious financial or reputational damage to the Company when determining whether an employee has

earned an annual cash incentive award or the amount of any such award.

Disclosure. Subject to our clawback and recoupment policies and provisions, we intend to disclose the general circumstances of any application of our clawback or recoupment policies and provisions against any executive officer (current or former) and the aggregate amount of compensation recovered. These provisions and policies do not limit any other action that the Company could take against an employee, including other disciplinary actions (including termination), ordinary course performance considerations, disclosure of wrongdoing to the government, and pursuit of any other legal claims against such employees.

#### Stock Ownership and Retention Guidelines
Our stock ownership guidelines require our executives to hold a meaningful amount of our Common Stock which promotes a long-term perspective in managing the Company, further aligning the interests of our executives and stockholders and mitigating potential compensation-related risk. Our guidelines require that each officer who has not met their ownership requirements must retain shares of our Common Stock acquired through the vesting of RSUs, the payout of performance units, and the exercise of stock options awarded (in each case, net of shares retained by us to satisfy associated tax withholding requirements and any applicable exercise price amounts) until such officer has reached his or her required stock ownership level.

Stock Ownership Guidelines Requirements

Our stock ownership guidelines are set forth in the table below. All executives currently employed by the Company and subject to stock ownership requirements were in compliance with their respective stock ownership requirement in 2025.<sup>(1)</sup>

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; Position | Stock Ownership Requirement  | Compliance  |
| &nbsp;&nbsp; Chief Executive Officer<sup>(2)</sup> | 6x base salary  | ✓ |
| &nbsp;&nbsp; Executive Vice President | 3x base salary  | ✓ |
| &nbsp;&nbsp; Senior Vice President | 2x base salary  | ✓ |
| &nbsp;&nbsp; Vice President | 1x base salary  | ✓ |

---

<sup>(1)</sup> As of October 15, 2025 (the effective date of executive certifications).

<sup>(2)</sup> Mr. Bradway holds more than 100 times his base salary, or more than 16 times his stock ownership requirement as of December 31, 2025.

The following holdings count towards satisfying these stock ownership requirements in 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• Shares of our Common Stock beneficially held, including shares not subject to forfeiture restrictions and shares underlying unvested restricted stock units;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• Shares of our Common Stock held through a 401(k) plan or other qualified pension or profit-sharing plan; and

&nbsp;&nbsp;&nbsp;&nbsp;• Shares purchasable with funds then allocated under our Employee Stock Purchase Plan.

<sup>(1)</sup> Includes accounting restatement correcting error (a) due to material noncompliance with financial reporting requirements that is material to previously issued financial restatements, or (b) that would result in a material misstatement if the error were corrected in the current period or left uncorrected. 

ï *2026 Proxy Statement*77

##### [**Table of Contents**](#toc)
Compensation Discussion and Analysis

Executives are generally given until December 31 of the fifth year following their placement into a given job level to comply with these guidelines. Executives who are promoted to a status with a stock ownership level higher than the executive was previously required to satisfy, have until December 31 of the third year to comply with the new ownership level if the executive has been subject to the stock ownership guidelines for five or more years. Once these ownership guidelines are met, executives are required to maintain such ownership until they change job levels or are no longer employed by us. As of October 15, 2025, the effective date of our executive certifications, all NEOs who were expected to meet such guidelines, were in compliance. Dr. Bradner has until December 31, 2028 to achieve compliance with these guidelines.

#### Insider Trading Policy and Procedures
We have adopted an Insider Trading Policy and procedures governing the purchase, sale and/or other dispositions of our securities by our Board, officers, employees, consultants, contract workers, and others (Covered Persons), as well as by the Company itself, that we believe are reasonably designed to promote compliance with Federal insider trading laws, rules and regulations, and the NASDAQ Stock Market listing standards. Our Insider Trading Policy prohibits Covered Persons from: (i) buying, selling, gifting or otherwise transacting in our Common Stock while aware of any material nonpublic information; (ii) engaging in short sales with respect to our Common Stock; (iii) pledging or purchasing our Common Stock on margin<sup>(1)</sup>; or (iv) entering into any derivative, hedging, or similar transactions with respect to our Common Stock, including any transactions that hedges or offsets, or is designed to hedge or offset, any decrease in the market value of our Common Stock. Examples of prohibited derivative transactions include, but are not limited to, purchases or sales of puts and calls (whether written or purchased or sold), options (whether "covered" or not), forward contracts, including, but not limited to, prepaid variable forward contracts; put and call "collars" ("European" or "American"), "equity" or "performance" swap or exchange agreements or any similar agreements or arrangements, however denominated, in our securities. A copy of our Insider Trading Policy was incorporated by reference as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

#### Policies for Grants of Long-Term Incentive Equity Awards
We do not grant equity awards in anticipation of the release of material nonpublic information and we do not time the release of material nonpublic information for the purpose of affecting the value of executive compensation. In an effort to avoid circumstances in which the grant of equity awards occurs while the Company is aware of material nonpublic information, our Compensation Committee has adopted an Equity Awards Policy that governs all grants of equity awards under our equity incentive plan, including stock options. In accordance with our Equity Awards Policy, our regular annual LTI equity award grants are typically approved by the Compensation Committee (for grants of equity awards to Senior Management, including our NEOs) or the Equity Award Committee (for grants to all other staff members) with a grant date that is the date that is two business days after the date of release of our first fiscal quarter earnings. Staff members may also receive special equity awards as determined by the applicable committee as new hires or for recognition and retention, promotions, or other purposes, and the effective date of such grants is generally also on the date that is two business days after the date of release of our quarterly or annual earnings after the date of determination by the applicable committee. Our Equity Awards Policy also provides that, in unusual and compelling circumstances, the grant date of an equity award may be the date at which the equity award is approved by the applicable committee (or a future date as specified by such committee), provided that any such grant date shall only be during a time when the Company and its officers are not prohibited from trading in the Company's securities.

#### Stockholder Outreach—Executive Compensation Website
We maintain a website accessible throughout the year at www.amgen.com/executivecompensation<sup>(2)</sup> which provides a link to our most recent proxy statement and invites our stockholders to fill out a survey to provide input and feedback to the Compensation Committee regarding our executive compensation policies and practices. All input from our stockholders is valuable and the Compensation Committee reviews your input and appreciates your time and effort in completing the survey.

Non-Direct Compensation and Payouts in Certain Circumstances

#### Offer Letter With Limited Severance Benefits
In connection with new hires, we typically enter into offer letters detailing their initial compensation and requirements to pay back certain elements of compensation, including for Dr. Bradner, as described further below. To attract talented executives from outside the Company, our offer letters may include severance terms that apply to terminations initiated by us and occur for reasons other than for "cause" within two years from the date of hire. These benefits may be provided to officer-level candidates to provide an incentive for them to join us by reducing the risks and costs associated with making such a job change. Other than the foregoing, our CEO and NEOs are not covered by employment agreements that provide for severance or other benefits in the event of termination.

#### Offer Letter–Dr. Bradner
Dr. Bradner commenced employment with the Company on December 18, 2023 and was subject to an offer letter that was negotiated in connection with his hiring. The terms of the offer letter were approved by the Compensation Committee and included our agreement to provide Dr. Bradner with a sign-on bonus to induce Dr. Bradner to accept our offer, $500,000 of which was paid in 2025. The offer letter also provided severance benefits in the event we terminated Dr. Bradner's employment without "cause" on or before December 18, 2025.

#### Change of Control and Severance Benefits
Double Trigger Change of Control Severance Plan

In the event of a change of control and a qualifying termination, our Change of Control Severance Plan provides severance payments to 2,136 U.S. staff members (as of December 31, 2025), including each NEO. There are no tax gross-up payments provided under the plan. The plan is structured so that payments and benefits are provided only if there is both a change of control and a termination of employment, either by us other than for "cause" or "disability" or by the participant for "good reason" (as each is defined in the plan)—sometimes referred to as a "double trigger"—because the intent of the plan is to provide appropriate severance benefits in the event of a termination following a change of control, rather than to provide a change of control bonus. The cash severance multiple for our CEO and all other NEOs is two times annual cash compensation. The payments and benefit levels under the Change of Control Severance Plan do not influence and were not influenced by other elements of compensation. The Change of Control

Severance Plan was adopted, and is continued by the Compensation Committee:

&nbsp;&nbsp;&nbsp;&nbsp;• To reinforce and encourage the continued attention and dedication of members of management to their assigned duties without the distraction arising from the possibility of a change of control;

&nbsp;&nbsp;&nbsp;&nbsp;• To enable and encourage management to focus their attention on obtaining the best possible deal for our stockholders and making an independent evaluation of all possible transactions, without being influenced by their personal concerns regarding the possible impact of various transactions on the security of their jobs and benefits; and

&nbsp;&nbsp;&nbsp;&nbsp;• To provide severance benefits to any participant who incurs a termination of employment under the circumstances described within a certain period following a change of control in recognition of their contributions to the Company.

Change of Control and Severance Treatment of Long-Term Incentive Equity Awards

#### Restricted Stock Units and Stock Options
All unvested RSUs and stock options have "double-trigger" acceleration of vesting that requires a qualifying termination in connection with a change of control. All RSUs and stock options vest in full only if the grantee's employment is involuntarily terminated (other than for "cause" or "disability") or, for a grantee subject to the Change of Control Severance Plan, voluntarily terminated with "good reason," in each case within two years following a change of control. All RSUs and stock options also vest in the event of a termination of employment due to death or "disability" as follows: full vesting for grants made before the year of death or disability; and pro-rata vesting (based on months worked) for grants made during the year of death or disability. In the event of "retirement," RSUs and stock options granted before the year of retirement continue vesting following retirement on their original vesting schedule, and for those awards granted in the year of retirement, they continue to vest pro-rata based on months worked. For stock options granted prior to January 1, 2025, if a retirement-eligible staff member retires, their stock options continue to vest and expire on the earlier of: (i) the fifth anniversary of their retirement date; or (ii) the end of the option term. For stock options granted subsequent to January 1, 2025, if a retirement-eligible staff member retires, their stock options continue to vest and expire at the end of the option term.

Compensation Discussion and Analysis

#### Performance Units
The Compensation Committee has maintained change of control features for each of the performance periods under our performance award programs to ensure that these programs reward participants for our performance until the successful closing of any change of control. In general, the performance period ends on the quarter end immediately prior to any change of control (target performance for the operating measures applies if the change of control occurs in the first year of a performance period and, otherwise, the operating measures are based on performance at the end of the last full year(s) within the truncated performance period). If the change of control occurs within the first six months of a performance period, the amount earned is pro-rated based on the number of months of the performance period prior to the change of control. In the event of a termination of employment due to death, disability, or retirement, our performance units provide for potential earn-out at the end of the performance period based on actual results with the amount earned pro-rated based on the termination date. For additional information on the levels of payout, see "Potential Payments Upon Termination or Change of Control—*Long-Term Incentive Equity Awards—Performance Units*" in our Executive Compensation Tables.

#### Limited Retirement Benefits and Deferred Compensation Plan
Health, retirement, and other benefits programs are generally available to our U.S.-based staff members, including our NEOs, with the overall benefit programs typically targeted to align in value with those programs offered by our peer group. The primary survey used to make this comparison is the Aon Benefit Index<sup>®</sup>, last updated as of June 2025*,* using a comparator group of 15 companies chosen by Amgen as representative of its peer group. The data generated from this survey is used by both the Compensation Committee and Company management in evaluating the competitive positioning and program design of these health, retirement, and other benefit programs.

#### Retirement and Savings Plan, Supplemental Retirement Plan, and Nonqualified Deferred Compensation Plan
Our Retirement and Savings Plan, or 401(k) Plan, is available to eligible U.S.-based staff members of the Company and participating subsidiaries (except Puerto Rico). All 401(k) Plan participants are eligible to receive the same proportionate level of matching and core contributions from us. Under the 401(k) Plan, we provide to each staff member a 5% contribution on eligible compensation and up to a 5% matching contribution on

voluntary deferrals. The Retirement and Savings Plan for Amgen Manufacturing Limited LLC is available to staff members in Puerto Rico.

Our Supplemental Retirement Plan, or SRP, is available to all 401(k) Plan participants and is designed to provide a "make whole" benefit to 401(k) Plan participants with eligible compensation in excess of the Internal Revenue Code's qualified plan compensation limit. The Company credits to the SRP a 10% contribution on eligible compensation in excess of the qualified plan compensation limit to represent the equivalent percentage of Company contributions that would have been made to the 401(k) Plan if the compensation had been eligible for deferral and was deferred into the 401(k) Plan at a level sufficient to receive the maximum matching contribution. Also, for amounts voluntarily deferred by a participant into the Nonqualified Deferred Compensation Plan, or NDCP, the Company credits to the SRP a 10% contribution on such amounts. Company contributions to the SRP on eligible compensation in excess of the qualified plan compensation limit are subject to a three-year cliff vesting requirement, with vesting accelerated under certain circumstances, and Company contributions to the SRP on amounts voluntarily deferred by a participant into the NDCP are fully vested.

The SRP enables us to provide the same percentage of base salary and annual cash incentive award as a retirement contribution to U.S.-based staff members at all levels.

The NDCP offers all U.S.-based staff members (including Puerto Rico) at director level and above the opportunity to defer eligible base salary and/or annual cash incentive awards, up to maximum amounts typically permitted in similar plans sponsored by our peer group. We also have the discretion to make contributions to this plan, and we do not make such contributions on a regular basis. In 2025, no Company contributions were made to the NDCP accounts of any NEOs. We believe that offering the NDCP is appropriate because it provides participants the opportunity to save for retirement in a tax-effective fashion not readily available without our sponsorship.

Earnings under the SRP and NDCP are market-based – there are no "above market" or guaranteed rates of returns offered in these plans. SRP and NDCP participants can direct notional account investments using the 401(k) Plan investing structure (excluding the self-direct brokerage and our Company stock) plus a variety of target date funds. Unlike a traditional pension plan, which generally provides a lifetime annuity that replaces a portion of a participant's final pay, any earnings from our 401(k) Plan, SRP, and NDCP are based on the investment return on the staff member's own investment elections, with the participant bearing the risk of investment gains and losses.

Compensation Discussion and Analysis

#### Health Savings Account and Retiree Medical Savings Account Plan for all U.S.-based Staff Members
We offer a high-deductible health plan and an associated health savings account that is generally available to U.S.-based (excluding Puerto Rico) staff members. We also maintain a Retiree Medical Savings Account Plan, or RMSA, available to U.S.-based (excluding Puerto Rico) staff members that allows all staff members to make after-tax deferrals to be used post-termination for reimbursement of eligible medical

expenses. Under the RMSA, the Company credits all eligible staff members with an annual contribution ($1,000) and makes a matching contribution equal to 50% of a staff member's own voluntary deferrals to the RMSA (to a maximum match of $1,500 per year). Company credits can be accessed to reimburse eligible medical expenses of staff members who terminate after having met the Company's retirement criteria. We do not offer a traditional Company-paid retiree medical plan to our NEOs or other U.S.-based staff members.

Accounting Standards

Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 718 requires us to recognize an expense for the fair value of equity-based compensation awards. Grants of stock options, RSUs, and performance units under our LTI equity award program are accounted for under FASB ASC Topic 718. The Compensation Committee regularly considers

the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our LTI equity award plans and programs. As accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

<sup>(1)</sup> Reflects base salary earned in each bi-weekly pay period (or portion thereof) during each fiscal year before pre-tax contributions and, therefore, includes compensation deferred under our nonqualified deferred compensation plan, or NDCP. Under payroll practices for salaried staff members of our U.S. entities, including our NEOs, base salary earned in a pay period is computed by dividing the annual base salary then in effect by 26, which is the number of full bi-weekly pay periods in a year. 

<sup>(2)</sup> Dr. Bradner was not an NEO in 2023. Dr. Bradner commenced employment with the Company on December 18, 2023. The amount shown in the bonus column for 2025 is the final cash payment of a sign-on bonus intended to induce Dr. Bradner to join the Company. See also the Agreement between Amgen Inc. and James Bradner, dated December 13, 2023, filed as Exhibit 10.14 to our Annual Report on Form 10-K for the year ended December 31, 2024. 

<sup>(3)</sup> For 2025, reflects the grant date fair values of performance units for the 2025-2027 performance period and restricted stock units, or RSUs, granted during 2025 determined in accordance with Accounting Standards Codification, or ASC, Topic 718 (see footnotes 6 and 7 to the "Grants of Plan-Based Awards" table for information on how these amounts were determined). 

The number of units to be earned for the performance units granted during 2025 is based on the average of our performance against two annual non-GAAP financial operating performance measures established at the commencement of the three year performance period, with the payout from performance against such measures modified up or down by our total shareholder return, or TSR, relative to the TSRs of the companies in the Standard & Poor's 500 Index, or S&P 500, all computed over the three-year performance period. These operating performance measures are performance conditions, as defined under ASC 718, while the relative TSR measure is a market condition under ASC 718. The values shown in this table and the "Grants of Plan-Based Awards" table are based on probable outcomes of these performance conditions as of the grant date, and target performance of the TSR market condition. The table below shows the grant date fair values under ASC 718 of these performance unit awards: (1) if the maximum is achieved with regard to all of the operating performance measures which would result in an earnout of 170% based on the operating performance measures with the TSR market condition at target, which would result in no increase or decrease of the 170% operating performance based on the TSR market condition; and (2) if the maximum is achieved with regard to all of the operating performance measures and maximum performance occurs under the TSR market condition which results in an additional 30% earnout, for total earned payout of 200% of performance units granted. <br>

<sup>(4)</sup> For 2025, reflects the grant date fair values of nonqualified stock options granted during 2025 determined in accordance with ASC 718 (see footnote 8 to the "Grants of Plan-Based Awards" table for information on how these amounts were determined). 

<sup>(5)</sup> Reflects amounts that were earned under our Executive Incentive Plan, or EIP, for 2025 performance which were determined and paid in March 2026 (see footnote 2 to the "Grants of Plan-Based Awards" table for information on how these amounts were determined). For a description of our EIP, see "Elements of Compensation and Specific Compensation Decisions—*Annual Cash Incentive Awards*" in our Compensation Discussion and Analysis. 

<sup>(6)</sup> See the subsection "All Other Compensation—Perquisites and Other Benefits" immediately following these footnotes.

All Other Compensation—Perquisites and Other Benefits

Perquisites. The amounts reported reflect the aggregate incremental cost of perquisites and other personal benefits provided to our NEOs and are included in the "All Other Compensation" column of the "Summary Compensation Table." The following table sets forth the perquisites provided to our NEOs in 2025.

<sup>(1)</sup> The aggregate incremental cost of use of our aircraft for personal travel by our NEOs is allocated entirely to the highest ranking NEO present on the planned flight (except for on-board catering costs which are allocated equally to each NEO present). If each NEO present on the flight is the same level, the aggregate incremental cost of use of our aircraft for personal travel is allocated equally to each NEO present. The aggregate incremental cost for personal use of our aircraft is calculated based on our variable operating costs, which include crew travel expenses, on-board catering, landing fees, trip-related hangar/parking costs, fuel, trip-related maintenance, and other smaller variable costs. In determining the incremental cost relating to fuel and trip-related maintenance, we applied an estimate derived from our average costs, consistent with the methodology used in prior years. We believe that the use of this methodology for 2025 is a reasonably accurate method for calculating fuel and trip-related maintenance costs. Because our aircraft are used primarily for business travel, we do not include fixed costs that do not change based on usage, such as pilot salaries, our aircraft purchase costs, and the cost of maintenance not related to trips. 

<sup>(2)</sup> The aggregate incremental cost for personal use of the car and driver provided by us is determined as the sum of the cost of fuel, driver overtime costs allocable to personal usage, and maintenance costs for the total number of personal miles driven. Personal miles include travel to and from work/home. As the cars are used primarily for business travel, fixed costs that would be incurred by us to operate the Company's cars for business use such as car lease or rental costs and driver salaries are not included.

<sup>(3)</sup> Other expenses include:

<sup>(a)</sup> For NEOs who were impacted by the January 2025 Southern California wildfires by the loss of their homes and vehicles, the Company provided limited disaster relief support of $116,326 for Mr. Griffith and $90,525 for Dr. Reese, primarily composed of short-term home security to protect Company assets. Additional support provided to Mr. Griffith included administrative assistance with disaster-related insurance documentation. 

<sup>(b)</sup> Enhancements made to the Company's executive security program in 2025 included measures such as cyber and digital security surveillance and enhanced residential security in the amount of $118,620 for Mr. Bradway, $6,334 for Messrs. Griffith and Gordon and Dr. Reese, and $3,167 for Dr. Bradner. For more information, see "Perquisites" in our Compensation Discussion and Analysis. 

<sup>(c)</sup> Dr. Bradner relocated from Massachusetts to Thousand Oaks, California in 2025. In accordance with our relocation policy for executives who agree to relocate on the Company's behalf, the incremental cost of certain relocation benefits that were provided to Dr. Bradner in 2025 in connection with his relocation include $103,121 to relocate household goods and $19,681 for home closing and other relocation costs. 

<sup>(d)</sup> Company contributions to non-profit charities designated by the executive in the amount of $10,000 for Messrs. Bradway, Gordon and Griffith and Dr. Bradner. 

<sup>(e)</sup> Annual executive physicals (available to all officers of the Company).

Other Benefits. The following table sets forth compensation for our NEOs in 2025 incurred in connection with our 401(k) Plan, our NDCP, and our SRP. These amounts, along with the perquisites and other benefits discussed above, are included in the "All Other Compensation" column of the "Summary Compensation Table." See "Nonqualified Deferred Compensation" below for a description of these plans.

<sup>(1)</sup> Reflects the date on which the grants were approved by the Compensation Committee.

<sup>(2)</sup> Represents awards to our NEOs made under our EIP. For our EIP participants, the "maximum" amounts shown in the table above reflect the largest possible payments under our EIP for the 2025 performance period, based on non-Generally Accepted Accounting Principles, or non-GAAP, net income, as defined for the EIP and reported and reconciled in **Appendix B**. There are no thresholds or targets under the EIP. The EIP provides that the Compensation Committee may use "negative discretion" to award any amount that does not exceed the maximum. Consistent with its practice since the EIP was approved by our stockholders, the Compensation Committee employed the pre-established Company performance goals under our Global Management Incentive Plan, or GMIP, as illustrated in the table below, in determining the actual amounts awarded under the EIP in 2025. 

**86** ï *2026 Proxy Statement*

##### [**Table of Contents**](#toc)
Executive Compensation Tables

Our 2025 Company performance goals under the GMIP were financial and operating performance goals weighted as follows: (1) Deliver Results (60%)—30% Revenues and 30% Non-GAAP Net Income (as reported and reconciled in **Appendix B**); (2) Progress Innovative Pipeline (30%)—20% Execute Key Clinical Studies & Regulatory Filings and 10% Advance Early Pipeline; and (3) Deliver Annual Priorities (10%). There are no payouts for below-threshold performance on any of our Company financial performance goals. Threshold performance on our "Progress Innovative Pipeline" and "Deliver Annual Priorities" goals results in 50% earned for those metrics. Certain measurements of performance for the non-financial metrics are more subjective in nature and for threshold performance could result in a very small payout percentage (less than 1% of an annual cash incentive award) and, as such, no threshold amounts are shown in the tables. The 2025 Company performance goals under the GMIP at target and maximum payout levels, which are based on a multiple of salary, are shown in the table below. Maximum performance under all of the performance metrics results in 225% of target payout opportunity being earned. The actual amounts awarded under our Company operating performance goals for 2025 were based on achievement of 136.0% performance against target and are reported as "Non-Equity Incentive Plan Compensation" in our "Summary Compensation Table" and are shown in the table below. For a description of our pre-established Company performance goals and the use of the GMIP in the Compensation Committee's exercise of negative discretion see "Elements of Compensation and Specific Compensation Decisions—*Annual Cash Incentive Awards*" in our Compensation Discussion and Analysis. <br>

<sup>(3)</sup> Reflects estimated payouts regarding performance units granted during 2025 for the 2025-2027 performance period for NEOs. The number of units granted (which equals the target number of units of the award) will be multiplied by a payout percentage, which can range from 0% to 200%, to determine the number of units earned by the participant at the end of the performance period. Shares of our Common Stock will be issued on a one-for-one basis for each performance unit earned. 

For all the NEOs, the payout percentage for the 2025-2027 performance period is earned based on the average of the three years of performance under the two non-GAAP annual operating measures, with the amount that can be earned under such operating measures ranging from 30% for threshold to 170% for maximum performance, which is then modified up or down by up to 30 percentage points based on our relative TSR performance ranking over the three-year performance period. All goals are set at the commencement of the three-year performance period. The non-GAAP operating measures are: (1) earnings per share; and (2) return on invested capital, or ROIC. Each of the operating measures are measured against goals established at the commencement of the three-year performance period for each year in the 2025-2027 performance period, which runs from January 1, 2025 through December 31, 2027. Each applicable operating measure is weighted equally (one-half per measure) to determine the total operating measure percentage for that year. At the end of the performance period, the final annual operating performance percentages for each of the three years are averaged to determine the score for the three-year performance period. The TSR modifier is based on how the TSR of our Common Stock ranks relative to the TSRs of the companies that are listed in the S&P 500 (the Reference Group), over the period from the date of grant through the end of the performance period. If the rank of the TSR of our Common Stock equals or exceeds the 75<sup>th</sup> percentile or equals or is less than the 25<sup>th</sup> percentile, the TSR modifier increases or decreases the payout by 30 percentage points, respectively. If the TSR of our Common Stock is at the 50<sup>th</sup> percentile, the TSR modifier is zero. Linear interpolation is used to determine the TSR modifier if the rank of the TSR of our Common Stock falls between these percentiles. If our absolute TSR over the performance period is less than 0, however, then the modifier cannot be greater than 0. The Compensation Committee certifies the number of performance units earned and payable following completion of the performance period. <br>

All performance units accrue dividend equivalents deemed reinvested in shares and that are payable in shares only when, and to the extent that, the underlying performance units are earned. For more information, see "Elements of Compensation and Specific Compensation Decisions—*Long-Term Incentive Equity Awards*" in our Compensation Discussion and Analysis. <br>

<sup>(4)</sup> Reflects the RSUs granted during 2025 to our NEOs. RSUs accrue dividend equivalents that are deemed reinvested in shares and payable only when, and to the extent that, the underlying RSUs vest and shares are issued to the recipient. RSUs granted during 2025 vest over four years in four equal annual installments on the first, second, third, and fourth anniversaries of the grant date, subject to continued service through the vesting date. 

<sup>(5)</sup> Reflects the 2025 annual grant of nonqualified stock options to our NEOs. Stock options granted during 2025 vest over four years in four equal annual installments on the first, second, third, and fourth anniversaries of the grant date, subject to continued service through the vesting date. 

<sup>(6)</sup> Reflects the grant date fair values of performance units granted to our NEOs for the 2025-2027 performance period determined in accordance with ASC 718, based on the number of performance units granted multiplied by: (i) the operating measure percentage earnout based on the probable outcomes of financial performance under the operating measures over the three-year performance period as of the grant date; and (ii) the grant date fair value per unit of $290.24, which reflects the impact of the TSR modifier of $19.80 per share, which is a market condition. The grant date fair value per unit was calculated using a payout

<sup>(c)</sup> Scheduled to vest in approximately equal amounts on each of the third and fourth anniversaries of the grant date. 

<sup>(d)</sup> Scheduled to vest on the fourth anniversary of the grant date.

<sup>(3)</sup> The market values of RSUs and performance units (and related dividend equivalents) were calculated by multiplying the number of RSUs outstanding or the number of performance units as determined in accordance with the SEC, rules and footnotes 4 through 6 below, as applicable, by the closing price of our Common Stock on December 31, 2025 ($327.31). 

<sup>(4)</sup> Reflects the sum of the number of performance units granted for the 2025–2027 performance period (January 1, 2025 to December 31, 2027) and the related dividend equivalents accrued through December 31, 2025, multiplied by the maximum payout percentage of 200%. As required by SEC rules, the maximum payout percentage is disclosed in the table because the estimated payout percentage as of December 31, 2025 is greater than the target level of performance of the performance units granted (based on the sum of: (1) the estimated outcomes of our operating measures to be achieved; and (2) the TSR modifier based on our TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 6, 2025 grant date to December 31, 2025. The number of dividend equivalents multiplied by the 200% payout percentage (rounded down to the nearest whole number of units) included in the table above are as follows: 1,519 units for Mr. Bradway; 447 units for Messrs. Griffith and Gordon; and 405 units for Drs. Reese and Bradner. Dividend equivalents are only paid when and to the extent the underlying performance units are earned and shares issued. 

<sup>(5)</sup> Reflects the sum of the number of performance units granted for the 2024–2026 performance period (January 1, 2024 to December 31, 2026) and the related dividend equivalents accrued through December 31, 2025, multiplied by the maximum payout percentage of 200%. As required by SEC rules, the maximum payout percentage is disclosed in the table because the estimated payout percentage as of December 31, 2025 is greater than the target level of performance of the performance units granted (based on the sum of: (1) the estimated outcomes of our operating measures to be achieved; and (2) the TSR modifier based on our TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 7, 2024 grant date to December 31, 2025. The number of dividend equivalents multiplied by the 200% payout percentage (rounded down to the nearest whole number of units) included in the table above are as follows: 3,099 units for Mr. Bradway; 826 units for Mr. Griffith and Dr. Reese; 912 units for Mr. Gordon; and 740 units for Dr. Bradner. Dividend equivalents are paid only when, and to the extent that, the underlying performance units are earned and shares issued. 

<sup>(6)</sup> Reflects the number of performance units granted for the 2023-2025 performance period (January 1, 2023 to December 31, 2025), and related dividend equivalents accrued through December 31, 2025, multiplied by the actual payout percentage of 124.0%, which is based on our actual performance under our operating measures of 105.6% and the relative TSR percentage modifier of 18.4 percentage points based on our actual TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 2, 2023 grant date to December 31, 2025. The number of dividend equivalents multiplied by the 124.0% payout percentage noted above (rounded down to the nearest whole number of units) included in the table above are as follows: 3,584 units for Mr. Bradway; 1,013 units for Mr. Griffith and Dr. Reese; and 1,126 units for Mr. Gordon.

Executive Compensation Tables

#### General Provisions of the Supplemental Retirement Plan and Nonqualified Deferred Compensation Plan
For 401(k) eligible staff members, the Company credits to the SRP a 10% contribution on eligible compensation earned in excess of the Internal Revenue Code's qualified plan compensation limit and on amounts voluntarily deferred by a participant into the NDCP. No "above market" crediting rates are offered under the SRP and employee contributions to the SRP are not permitted.

The SRP and the NDCP are unfunded plans for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended. Deferred amounts are our general unsecured obligations and are subject to our ongoing financial solvency. We have established a grantor trust (a so-called "rabbi" trust) for the purpose of accumulating funds to assist us in satisfying our obligations under the NDCP. Earnings on amounts contributed to our SRP and NDCP, like our 401(k) Plan, are based on participant selections among the deemed investment options selected by an internal committee. This committee has the sole discretion to discontinue, substitute, or add investment options at any

time. Participants can select from among these investment options for purposes of determining the earnings or losses that we will credit to their plan accounts, but they do not have an ownership interest in the investment options they select. Unlike our 401(k) Plan, we do not offer the opportunity for NDCP or SRP participants to invest through a brokerage window or in our Common Stock. The investment options available to NDCP and SRP participants also differ from our 401(k) in that they include six target date portfolios which are used as default investment options (the "Target Retirement Portfolios"). The investment options available during 2025 are described in the subsection "Investment Options Under the 401(k), Supplemental Retirement, and Nonqualified Deferred Compensation Plans" below. Invested credits can be reallocated among available plan investment options on any business day and effective at the close of business on that day (subject to the time of day the reallocation request is made on a day the market is open).

#### Retirement and Savings Plan (401(k) Plan) and Supplemental Retirement Plan
Our 401(k) Plan is a qualified plan available to regular U.S.-based staff members of the Company and participating subsidiaries (except Puerto Rico). All 401(k) Plan participants, including our NEOs, are eligible to receive the same proportionate level of matching and nonelective or "core" contributions from us. Company contributions on eligible compensation earned above the Internal Revenue Code qualified plan compensation limit and on amounts that were voluntarily deferred by a staff member to the NDCP are credited to our SRP, a nonqualified plan that is available to all 401(k) Plan-eligible staff members.

Contributions. We make a core contribution of 5% of eligible compensation to all regular U.S.-based staff members under the 401(k) Plan, regardless of whether the staff members elect to defer any of their own compensation to the 401(k) Plan. In addition, participants are eligible to receive matching contributions of up to 5% of eligible compensation they contribute to the 401(k) Plan (up to maximum contribution limits allowed under the Internal Revenue Code). As discussed above, under our SRP, we credit 10% of each participant's eligible compensation that is in excess of the qualified plan compensation limit. We also credit to the SRP 10% of each participant's compensation they elect to defer to the NDCP.

Distributions. Participants receive distributions from the SRP following their termination of employment. Participants may elect to receive distributions as a lump sum payment

in the first or second year following termination of employment, or, for balances in excess of $100,000, in installments that commence in the year following termination. For our NEOs, Section 409A of the Internal Revenue Code generally requires that their distributions may not occur earlier than six months following our NEO's termination of employment.

**Vesting.**Participants in the 401(k) Plan are immediately vested in participant and matching contributions and related earnings and losses on such amounts. Participants in the 401(k) Plan who were hired before January 1, 2020 are also immediately vested in core contributions and related earnings and losses on such amounts. Participants in the 401(k) Plan who were hired on or after January 1, 2020 will only become 100% vested in core contributions and related earnings and losses on such amounts after three years of service. Participants in the SRP are immediately vested in matching contributions that are made by us with respect to amounts the participants deferred under the NDCP and related earnings and losses on such amounts, and are fully vested in the remainder of their accounts upon the earlier of: (i) three continuous years of their service to us; (ii) termination of their employment on or after their normal retirement date (as defined in the 401(k) Plan); (iii) their disability (as defined in the 401(k) Plan); (iv) their death; or (v) a change of control and termination of their employment as described below in "Potential Payments Upon Termination or Change of Control—*Change of Control Severance Plan*."

##### [**Table of Contents**](#toc)
Executive Compensation Tables

#### Nonqualified Deferred Compensation Plan
Our NDCP allows participants to defer receipt of a portion of their eligible compensation to a future date, with an opportunity to earn tax-deferred returns on the deferrals. Members of our Board of Directors, or Board, and our U.S.- and Puerto Rico-based staff members at the director level or above, which include our NEOs, are eligible to participate in this plan. All participants in this plan participate on the same basis.

Contributions. Participants who are staff members may elect to defer up to a maximum of 50% of their eligible base salary, up to a maximum of 80% of their annual cash incentive award, and up to 80% of sales commissions. Non-employee members of our Board may defer all or a portion of their fees, including retainers and meeting fees. In addition, we may, in our sole discretion, contribute additional amounts to any participant's account at any time, such as contributing sign-on bonuses to the

accounts of newly hired staff members or for retention purposes.

**Distributions.** Participants may elect to receive distributions as a lump sum or, for balances in excess of $100,000, in annual installments for up to ten years. For most participants, distributions commence in the first or second year following the participant's termination of employment. For our NEOs, Section 409A of the Internal Revenue Code generally requires that distributions may not occur earlier than six months following our NEO's termination of employment. Participants may also petition for a distribution due to an unforeseeable financial hardship.

**Vesting.** Participants are at all times 100% vested in the amounts they elect to defer and related earnings and losses on such amounts.

#### Investment Options Under the 401(k), Supplemental Retirement, and Nonqualified Deferred Compensation Plans
The investment options under the 401(k), the SRP, and the NDCP are substantially the same and the associated rates of return are contained in the tables below. For the SRP and the NDCP only, six target retirement portfolio options (referred to as "Target Retirement Portfolios" below) are among the deemed investment options and are based on different target retirement dates and designed to provide an all-in-one investment option for creating a diversified portfolio. Each portfolio is an asset allocation strategy built around a combination of investments that is adjusted over time to gradually

become more conservative as the target maturity date of the portfolio approaches.

For the 401(k) Plan only, participants may make investments in our Common Stock (no more than 20% of the value of a participant's account) and access a self-directed brokerage window. Since these options are only available in the 401(k) Plan, the performance of these additional investment options is not included in the following table.

Potential Payments Upon Termination or Change of Control

#### Change of Control Severance Plan
Our Amended and Restated Change of Control Severance Plan, or Change of Control Severance Plan, provides a lump sum payment and certain other benefits for each participant in the plan who separates from employment with us in connection with a change of control only. Our Compensation Committee periodically reviews the terms of the Change of Control Severance Plan, which was originally adopted in 1998, to ensure it is aligned with current governance best practices. No tax gross-up payments are provided under the Change of Control Severance Plan. If a change of control occurs and a participant's employment is terminated by us other than for cause or disability, or is terminated by the participant for good reason, within two years after the change of control, a participant under the Change of Control Severance Plan would be entitled to:

&nbsp;&nbsp;&nbsp;&nbsp;• a lump sum cash payment in an amount equal to the product of:

– a benefits multiple of one or two based on the participant's position (each of our NEOs has a benefits multiple of two); and

– the sum of (i) the participant's annual base salary immediately prior to termination or, if higher, immediately prior to the change of control, plus (ii) the participant's targeted annual cash incentive award for the year in which the termination occurs;

&nbsp;&nbsp;&nbsp;&nbsp;• if, as a result of the participant's termination of employment, the participant becomes entitled to, and timely elects to continue, healthcare (including any applicable vision benefits) and/or dental coverage under Consolidated Omnibus Budget Reconciliation Act of 1985, or COBRA, Company-paid group health and dental insurance continuation coverage for the participant and his or her dependents under COBRA until the earlier of (i) the expiration of a participant's eligibility for coverage under COBRA, or (ii) the expiration of the 18-month period immediately following the participant's termination (whichever occurs earlier); and

&nbsp;&nbsp;&nbsp;&nbsp;• either a lump-sum cash payment or a contribution to our SRP, as determined by us in our sole discretion, in an amount equal to the sum of (1) the product of $2,500 and the participant's benefits multiple, plus (2) the product of (x) 10%, (y) the sum of (i) the participant's annual base salary as in effect immediately prior to the participant's termination or, if higher, as in effect immediately prior to the change of control, plus (ii) the participant's targeted annual cash incentive award for the year in which the termination occurs (which equals the participant's annual base salary multiplied by the

participant's target annual cash incentive award percentage, each as in effect immediately prior to the termination or, if higher, as in effect immediately prior to the change of control), and (z) the benefits multiple; and indemnification and, if applicable, directors' and officers' liability insurance provided by us for four years following the participant's termination (each of our NEOs would receive such liability insurance benefits, which would result in no additional cost to us). <br>

If all payments or benefits received under the Change of Control Severance Plan or any other plan, arrangement, or agreement would cause the participant to be subject to excise tax, then the payments will be reduced to the extent necessary to avoid the excise tax, provided that the reduced payments, net of federal, state, and local income taxes, are greater than the payments without such reduction, net of federal, state, and local income taxes, and excise tax.

The plan provides that the benefits described above would be provided in lieu of any other severance benefits that may be payable by us (other than accrued vacation and similar benefits otherwise payable to all staff members upon a termination). The plan also provides that the benefits described above may be forfeited if the participant discloses our confidential information or solicits or offers employment to any of our staff members during a period of years equal to the participant's benefits multiple following the participant's termination.

The plan is subject to automatic one-year extensions unless we notify participants no later than November 30 that the term will not be extended. If a change of control occurs during the term of the plan, the plan will continue in effect for at least 24 months following the change of control. Prior to a change of control, we can amend the plan at any time. After a change of control, the plan may not be terminated or amended in any way that adversely affects a participant's interests under the plan, unless the participant consents in writing.

"Change of Control" is defined in the plan as the occurrence of any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;• any person, entity, or group has acquired beneficial ownership of 50% or more of (i) our then outstanding common shares, or (ii) the combined voting power of our then outstanding securities entitled to vote in the election of directors;

&nbsp;&nbsp;&nbsp;&nbsp;• individuals making up the incumbent Board (as defined in the plan) cease for any reason to constitute at least a majority of our Board;

**94** ï *2026 Proxy Statement* 

------

##### [**Table of Contents**](#toc)
Executive Compensation Tables

&nbsp;&nbsp;&nbsp;&nbsp;• immediately prior to our consummation of a reorganization, merger, or consolidation with respect to which persons who were the stockholders of the Company immediately prior to such transaction do not, immediately thereafter, own more than 50% of the then outstanding shares of the reorganized, merged, or consolidated company entitled to vote generally in the election of directors;

&nbsp;&nbsp;&nbsp;&nbsp;• a liquidation or dissolution of the Company or the sale of all or substantially all of the assets of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;• any other event which the incumbent Board (as defined in the plan), in its sole discretion, determines is a change of control.

"Cause" is defined in the plan as (i) conviction of a felony or (ii) engaging in conduct that constitutes willful gross neglect or willful gross misconduct in carrying out the participant's duties, resulting in material economic harm to us, unless the participant believed in good faith that the conduct was in, or not contrary to, our best interests.

"Disability" under the plan is determined based on our long-term disability plan as is in effect immediately prior to a change of control.

"Good reason" is defined in the plan as (i) an adverse and material diminution of a participant's authority, duties, or responsibilities, (ii) a material reduction in a participant's base salary, (iii) an increase in a participant's daily commute by more than 100 miles roundtrip, or (iv) any other action or inaction by the Company that constitutes a material breach of the agreement under which the participant provides services. In order to terminate with "good reason," a participant must provide written notice to the Company of the existence of the condition within the required period, the Company must fail to remedy the condition within the required time period and the participant must then terminate employment within the required time period.

#### Long-Term Incentive Equity Awards
Stock Options and Restricted Stock Units

Our stock plans (or the related grant agreements approved for use under such stock plans) provide for accelerated vesting or continued vesting of unvested stock options and RSUs in the circumstances described below.

Double-Trigger Qualifying Termination in Connection with a Change of Control. Unvested stock options and RSUs will vest in full in connection with a Change of Control (as defined in the stock plans or related grant

agreements approved for use under such stock plans) only if and when, within 24 months following the Change of Control, the grantee's employment is involuntarily terminated other than for "cause" or "disability," and, in the case of staff members subject to the Change of Control Severance Plan, voluntarily terminated with "good reason" (as each is defined in the grant agreements).

Death or Disability. In general, unvested stock options and RSUs granted in calendar years prior to the year death or disability occurs vest in full upon the occurrence of such event. For unvested stock options and RSUs granted in the calendar year death or disability occurs, a pro-rata amount of these stock options and RSUs immediately vests based on the number of completed months of employment during the calendar year such event occurs. Under our stock plans, a disability has the same meaning as under Section 22(e)(3) of the Internal Revenue Code and occurs where the disability has been certified by either the Social Security Administration, the comparable government authority in another country with respect to non-U.S. staff members, or an independent medical advisor appointed by us.

Retirement. In general, unvested stock options and RSUs granted in calendar years prior to the year in which an employee retires continue to vest on their original vesting schedule following the retirement of the holder if the holder has been employed for at least ten years and is age 55 or older or is age 65 or older, regardless of service (a retirement-eligible participant), provided that any unvested RSUs will vest in full in the event of death following such holders' retirement from the Company. If a retirement-eligible participant receives a grant of stock options or RSUs in the calendar year such retirement occurs, generally, the participant will continue to vest in a pro-rata amount of the award he or she would be otherwise entitled based upon the number of complete months of employment during the calendar year such retirement occurs. For stock options granted prior to January 1, 2025, retirement-eligible participants have the lesser of five years from the date of retirement or the remaining option term to exercise their vested stock options granted. For stock options granted on or after January 1, 2025, retirement-eligible participants may exercise vested stock options through the full option term. Mr. Bradway, Dr. Reese, and Mr. Griffith are each eligible to receive these retirement benefits, having become retirement-eligible in 2018, 2017 and 2024, respectively.

Performance Units

Performance units are generally forfeited unless a participant is continuously employed through the last business day of the performance period. The underlying principle is that the participant needs to have been an

ï *2026 Proxy Statement*95

------

##### [**Table of Contents**](#toc)
Executive Compensation Tables

active employee during the entire performance period in order to have contributed to the results on which the earned awards are based. Exceptions to this treatment are a termination of employment in connection with a change of control or the death, disability, or retirement of a participant.

**Change of Control.** Generally, with respect to grants of outstanding performance units, the performance period terminates as of the last business day of the last completed fiscal quarter preceding the change of control. The TSR market condition performance is based on: (A) our TSR performance for which our ending Common Stock price is computed on the greater of (i) the average daily closing price of our Common Stock for the last twenty (20) trading days of such shortened period, or (ii) the value of consideration paid for a share of our Common Stock in the change of control (whether such consideration is paid in cash, stock or other property, or any combination thereof); and (B) the TSR performance of the companies in the applicable reference group based on such companies' average daily closing stock price for the last twenty (20) trading days of such shortened performance period. With respect to the operating performance measures, if the change of control occurs: (i) during the first fiscal year of the performance period, target levels of performance shall be used to calculate the payment; and (ii) subsequent to the first fiscal year of the performance period, actual levels of performance for the completed full fiscal year(s) within the performance period that were completed prior to the year of the change of control shall be used to calculate the payment. In the event of a change of control during the first six months of the performance period, however, the participant is entitled to a payment equal to an amount calculated in the manner described above, but pro-rated for the number of complete months elapsed during the shortened performance period.

Death or Disability. For all performance unit grants made in calendar years prior to the year death or disability occurs, the participant will be paid the full amount of the award he or she would be otherwise entitled to, if any, as determined at the end of the performance period. For a performance unit grant made in the calendar year in which death or disability occurs, a participant will be paid a pro-rata amount of the award he or she would otherwise be entitled to, if any, as determined at the end of the performance period, based upon the number of complete months of employment in the calendar year such event occurs.

Retirement. In the event of retirement of a participant who is a retirement-eligible participant, for performance unit grants made in calendar years prior to the year in which retirement occurs, the participant will be paid the

full amount of the award he or she would be otherwise entitled to, if any, as determined at the end of the performance period. If a retirement-eligible participant receives a performance unit grant in the calendar year such retirement occurs, the participant will be paid a pro-rata amount of the award he or she would be otherwise entitled to, if any, as determined at the end of the performance period, based upon the number of complete months of employment during the calendar year such retirement occurs. Mr. Bradway, Dr. Reese, and Mr. Griffith are each eligible to receive this benefit, having become retirement-eligible in 2018, 2017 and 2024, respectively.

#### Expired Severance Terms in Dr. Bradner's Offer Letter
We entered into an offer letter with Dr. Bradner in connection with the commencement of his employment with the Company on December 18, 2023, which provides for limited severance benefits in the event of termination of employment by us, other than for "cause." We generally provide these terms in our offer letters with newly hired executive officers. Specifically, Dr. Bradner's offer letter provides for cash severance protection for two years following his employment date equal to two (2) years' annual base salary and two (2) times target annual cash incentive award, plus up to 12 months of COBRA medical and dental coverage paid for by us. Benefits of this type are provided to officer-level candidates to provide an incentive to them to join our Company by reducing the risk of making such a job change. These severance benefits for Dr. Bradner expired on December 18, 2025, and were payable only if the executive is terminated other than for "cause."

#### Estimated Potential Payments
The tables below set forth the estimated current value of payments and benefits: (i) to each of our NEOs upon a change of control, upon a qualifying termination within two years following a change of control, or upon death or disability and (ii) to Messrs. Bradway and Griffith and Dr. Reese upon retirement. All amounts shown in the tables below assume that the triggering events occurred on December 31, 2025 and do not include: (i) the 2023-2025 performance unit awards and the 2025 EIP payouts, which were earned as of December 31, 2025; (ii) other benefits earned during the term of our NEO's employment that are available to all salaried staff members, such as accrued vacation; (iii) benefits paid by insurance providers under life and disability policies; and (iv) benefits previously accrued and vested under the SRP and the NDCP. For information on the accrued amounts payable under these plans, see the "Nonqualified Deferred Compensation" table above. The actual

**96** ï *2026 Proxy Statement* 

------

##### [**Table of Contents**](#toc)
Executive Compensation Tables

amounts of payments and benefits that would be provided can only be determined at the time of a change of control and/or the NEO's separation from the Company. In accordance with SEC rules, the value of accelerated equity awards shown in the tables below was calculated using the closing price of our Common Stock on December 31, 2025 ($327.31). The amounts shown for accelerated stock options is the difference between the closing price at December 31, 2025 ($327.31), and the exercise price of unvested stock

options multiplied by the number of unvested stock options. The value per unit of accelerated RSUs and the payout of performance units, including the related accrued dividend equivalents (rounded down to the nearest whole number of units), equals the closing price at December 31, 2025 ($327.31) multiplied by the number of units and dividend equivalents that would be deemed vested or earned, as applicable, as a result of such event.

Executive Compensation Tables

<sup>(1)</sup> In the event of retirement of a retirement-eligible NEO, unvested stock option and RSU awards remain outstanding and continue to vest on the regularly scheduled vesting dates. For purposes of the payout values shown in the tables above, the values of the unvested awards are based on the closing price of our Common Stock on December 31, 2025 ($327.31). 

<sup>(2)</sup> In the event of a change of control (with or without a qualifying termination) that occurs after the first six months of the 2025-2027 performance period, the number of performance units that would have been earned is the sum of the number of performance units granted and related dividend equivalents accrued through December 31, 2025, multiplied by a payout percentage of 88.1%, which employs the plan dictated target level of performance for the operating performance measures of 100% modified down by 11.9 percentage points by the TSR modifier, based on our TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 6, 2025 grant date through September 30, 2025, the last business day of the last fiscal quarter before the change in control. 

In the event of a change of control occurring (with or without a qualifying termination) that occurs during the second year of the 2024-2026 performance period, the number of performance units that would have been earned is the sum of the number of performance units granted and related dividend equivalents accrued through December 31, 2025, multiplied by a payout percentage of 80.0%, which is the percentage based on the estimated outcomes of our operating performance measures achieved during the performance period ending December 31, 2024 of 104.9% modified down by 24.9 percentage points by the TSR modifier, based on our TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 7, 2024 grant date to September 30, 2025, the last business day of the last fiscal quarter before the change of control. <br>

Our TSRs for purposes of determining the payout percentages of these awards would be based on the higher of: (i) the average closing price of our Common Stock for the last 20 trading days of the shortened performance period ended on September 30, 2025 of $279.06; and (ii) the value of consideration the acquirer paid for a share of our Common Stock in the change of control. For purposes of the payout values shown in the tables, the TSRs for our Common Stock were based on the respective actual TSRs over the respective averaging periods ending September 30, 2025, the last business day of the last fiscal quarter before the change in control. The resulting number of units that would have been so earned was multiplied by $327.31, the closing price of our Common Stock on December 31, 2025. <br>

For information on the performance units, see "Elements of Compensation and Specific Compensation Decisions—*Long-Term Incentive Equity Awards*" in our Compensation Discussion and Analysis.

<sup>(3)</sup> In the event death or disability occurs, the participant is entitled to the number of performance units that would have been earned by the NEO if he had remained employed for the entire performance period. For purposes of the payout values shown in the tables, the number of units that would have been earned was multiplied by $327.31, the closing price of our Common Stock on December 31, 2025. 

For the 2025-2027 performance period, the number of performance units that would have been earned has been estimated as the sum of the number of performance units granted and related dividend equivalents accrued through December 31, 2025, multiplied by the payout percentage of 133.3%. The payout percentage is based on the estimated outcomes of our operating performance measures to be achieved during the performance period ending December 31, 2025 of 105.1%, which was increased by the TSR modifier by 28.2 percentage points based on our TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 6, 2025 grant date to December 31, 2025. <br>

For the 2024-2026 performance period, the number of performance units that would have been earned has been estimated as the sum of the number of performance units granted and related dividend equivalents accrued through December 31, 2025, multiplied by the payout percentage of 102.0%. The payout percentage is based on the estimated outcomes of our operating performance measures to be achieved during the performance period ending December 31, 2025 of 104.0%, which was decreased by the TSR modifier by 2.0 percentage points based on our TSR percentile rank relative to the TSRs of the companies in the Reference Group for the period from the May 7, 2024 grant date to December 31, 2025. <br>

In the event of actual death or disability, payout of shares in satisfaction of amounts earned for grants for the 2025-2027 and 2024-2026 performance periods would not occur until after the end of the performance periods and would be based on actual performance through the end of the performance period. For more information, see "Elements of Compensation and Specific Compensation Decisions—*Long-Term Incentive Equity Awards*" in our Compensation Discussion and Analysis. <br>

As Mr. Bradway, Mr. Griffith, and Dr. Reese were retirement-eligible as of December 31, 2025, the retirement payout amounts for performance units for the 2025-2027 and 2024-2026 performance periods were calculated in the same manner as the respective death and disability amounts. <br>

<sup>(5)</sup> Reflects the value of retirement plan contributions for two years calculated as two times the sum of: (i) $2,500; and (ii) the product of: (a) 10% multiplied by (b) the sum of the NEO's annual base salary as of December 31, 2025, and the NEO's targeted annual cash incentive award for 2025 (which equals the NEO's annual base salary as of December 31, 2025, multiplied by the NEO's target annual cash incentive award percentage for 2025).

## Other Compensation Matters
Pay Ratio

The following is a reasonable estimate, prepared under applicable SEC rules, of the ratio of the annual total compensation of our CEO to the median of the annual total compensation of our other staff members, calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K. The Company determined our median employee based on target total direct compensation paid to all our staff members worldwide and recorded in our global human resources systems as of December 31, 2025. Target total direct compensation included base salary, target annual cash incentive award opportunity for the period, and the target annual grant value of long-term incentive equity awards during 2025. Earnings of our staff members outside of the U.S. were converted to U.S. dollars using

currency exchange rates as of December 31, 2025. No cost-of-living adjustments were made. We then determined the annual total compensation of our median employee for 2025 which was $154,123. As disclosed in the "Summary Compensation Table" appearing on page 83, our CEO's annual total compensation for 2025 was $24,693,120. Based on the foregoing, the ratio of the annual total compensation of our CEO to that of the median staff member was 160 to 1. For information on the determination of executive compensation, please see "Compensation Committee Processes and Procedures for Considering and Determining Executive Compensation in 2025" above and our Compensation Discussion and Analysis beginning on page 46.

Pay Versus Performance

As required, below is disclosure of the compensation of the Company's Named Executive Officers, or NEOs, for the last five fiscal years calculated in accordance with Item 402(v) of Regulation S-K. Item 402(v) requires disclosure of "compensation actually paid" based on calculations that report changes in the fair value of equity awards granted in prior years, granted during the fiscal year, and vesting during the fiscal year, but that do

not reflect the actual amount of compensation earned or received by any of the NEOs during the fiscal year.

For information about our compensation philosophy and how we align executive compensation with our performance, please see our "Compensation Discussion and Analysis."

<sup>(2)</sup> Stock option fair values are calculated at each measurement date using a Black-Scholes valuation model, consistent with the approach used to value the awards at the grant date. Stock option fair values as of each measurement date were determined using updated assumptions as of such measurement date that include closing prices of our Common Stock of between $281.22 and $327.31, risk-free interest rates of between 3.4% and 3.8%, expected life of between 1.4 and 4.2 years, expected volatility of the price of our Common Stock of between 25.2% and 27.8%, and an expected dividend yield of 3.2%. Changes in fair value are primarily driven by increases or decreases in the price of the Company's Common Stock as of each measurement date. 

Performance unit fair values are calculated using a payout simulation model, consistent with the approach used to value the awards at the grant date. Performance unit fair values as of each measurement date were determined using updated assumptions as of such measurement date that include a risk-free interest rate of 3.4%, expected volatility of the price of our Common Stock of between 26.5% and 27.4%, the closing price of our Common Stock of $327.31, and expected volatilities of the prices of the stocks of the Reference Group (as defined in footnote 3 to the "Grant of Plan-Based Awards" table in our Executive Compensation Tables), and the correlations of returns of our Common Stock and the stocks of the Reference Group to simulate total shareholder returns and their resulting impact on the payout percentages based on the contractual terms of the performance units). Changes in fair value are primarily driven by increases or decreases in the price of the Company's Common Stock as of each measurement date. <br>

<sup>(3)</sup> Pursuant to the SEC rules, total shareholder return, or TSR, reflects an initial investment of $100 on December 31, 2020. All values assume reinvestment of the pretax value of dividends, are calculated as of December 31 of each year, and are weighted according to the respective issuers' stock market capitalization at the beginning of each period for which a return is indicated. 

<sup>(4)</sup> The peer group TSR reflected in the table aligns with the executive compensation peer group described in our Compensation Discussion and Analysis, which peer group was changed for fiscal year 2025 with the addition of Vertex Pharmaceuticals Incorporated, or Vertex. The addition of Vertex to the 2025 executive compensation peer group was based, in part, on the recommendation of FW Cook, including that Vertex: (i) met the peer group objective size criteria employed by the Compensation Committee; (ii) identified the Company as a peer; and (iii) was identified as a peer of our Company by three of our peers and certain proxy advisory firms. The peer group for each listed fiscal year consists of the following companies: AbbVie, Inc.; AstraZeneca plc; Biogen Inc.; Bristol Myers Squibb Company; Eli Lilly and Company; Gilead Sciences, Inc.; GlaxoSmithKline plc; Johnson & Johnson; Merck & Co., Inc.; Novartis AG; Pfizer Inc.; Regeneron Pharmaceuticals, Inc.; Roche Holding AG; Sanofi S.A.; and Vertex. The peer group TSR would have been $123.31, $136.63, $137.38, $149.05, and $192.43 for fiscal years 2021 through 2025, respectively, had our executive compensation peer group remained the same and excluded Vertex.

Director Compensation

## Director Compensation
The compensation program for our non-employee directors is intended to be competitive and fair so that we can attract the best talent to our Board of Directors, or Board, and recognize the time and effort required of a director given the size and complexity of our operations. In addition to cash compensation, we provide equity

grants and have stock ownership guidelines to align the directors' interests with our stockholders' interests and to focus on our long-term growth and success. Directors who are our employees are not paid any fees for serving on our Board or for attending Board meetings.

Equity Incentives. Each non-employee director received an automatic annual grant of restricted stock units, or RSUs, on the date of the annual meeting of stockholders, with a grant date fair market value of $220,000, based on the closing price of our Common Stock on the grant date (rounded down to the nearest whole number). The RSUs vest immediately, and to further support long-term holding, a director may choose to defer receipt of such shares. Directors who elect to defer receipt of the shares accrue dividend equivalents on the vested RSUs during the deferral period. Further, to increase their equity holdings, a director may also elect to receive deferred vested RSUs in lieu of up to 100% of his or her cash compensation.

Director Stock Ownership Guidelines. All non-employee directors are expected to hold the equivalent of five times the Board annual cash retainer ($575,000) in our Common Stock while serving as a non-employee director.

All non-employee directors are expected to comply with the stock ownership guidelines on or before

December 31<sup>st</sup> of the calendar year in which the fifth anniversary of their first date of election by stockholders falls. For purposes of the Board stock ownership guidelines, issued and outstanding shares of our Common Stock held beneficially or of record by the non-employee director, issued and outstanding shares of our Common Stock held in a qualifying trust (as defined in the guidelines), and vested RSUs that are deferred will count towards satisfying these stock ownership guidelines. All directors with compliance dates that were on or prior to December 31, 2025, met the stock ownership guidelines as of those dates.

Board members are subject to our insider trading policy that, among other things, prohibits engaging in short sales with respect to the Company's securities, purchasing or pledging the Company's stock on margin<sup>(1)</sup>, or entering into any hedging, derivative, or similar transactions with respect to the Company's securities.

<sup>(1)</sup> With the exception of the use of a margin account to purchase our common stock in connection with the exercise of Amgen-granted stock options (*i.e.*, "cashless exercises").

Director Compensation

Expenses. Directors are entitled to reimbursement of their expenses incurred in connection with attendance at Board and committee meetings and conferences with management. Guests of our Board members are occasionally invited to Board events, and we may pay or reimburse travel expenses and may provide transportation on our aircraft for both the director and his or her guest. We make tax gross-up payments to our directors to reimburse them for additional income taxes imposed when we are required to impute income on perquisites*.*

Deferred Compensation. Non-employee directors are eligible to participate in the Nonqualified Deferred Compensation Plan that we maintain for our staff members (see "Nonqualified Deferred Compensation" in our Executive Compensation Tables above for more

information). Earnings under this plan are market-based—there are no "above market" or guaranteed rates of returns.

Charitable Contributions. Through The Amgen Foundation, Inc., the Company maintains a charitable contributions matching gift program for all eligible staff members and non-employee directors. The Amgen Foundation, Inc. matches, on a dollar-for-dollar basis, qualifying donations made by directors to eligible organizations, up to $20,000 per person, per year. Separate from, and in addition to, this ongoing annual program, in response to catastrophic events and natural disasters, The Amgen Foundation, Inc. matches, on a dollar-for-dollar basis, donations to specified disaster relief organizations.

Director Compensation Table

The following table shows compensation of the non-employee members of our Board for 2025. Robert A. Bradway, our Chairman of the Board, Chief Executive Officer and President is not included in the table as he is an employee and, thus, receives no compensation for his service as a director.

Such grant dates occurred on the date that is two business days after release of our applicable quarterly earnings in accordance with the terms of our Director Equity Incentive Program. <br>

<sup>(4)</sup> Directors may elect to defer issuance of shares until a later date, which would result in a deferral of taxable income to the director until the lapse of such deferral. Upon the lapse of any applicable deferral period, the vested/deferred RSUs are paid in shares of our Common Stock on a one-for-one basis. The table below shows the aggregate number of deferred stock awards (vested deferred RSUs and dividend equivalents) outstanding for each non-employee director as of December 31, 2025. Deferred stock awards consist of vested RSUs for which receipt of the underlying shares of our Common Stock has been deferred (vested/deferred RSUs) and dividends on vested/deferred RSUs are deemed automatically reinvested to acquire additional vested/deferred RSUs. No other unvested or deferred equity awards are held by our non-employee directors.

<sup>(a)</sup> These are charitable contributions of The Amgen Foundation, Inc. that matched the directors' charitable contributions made in 2025.

<sup>(b)</sup> Where guests accompany directors on our aircraft or where the director, for nonbusiness purposes, accompanies executives using our aircraft for business purposes, we typically incur de minimis incremental costs for transporting that person, and we are required to impute income for such de minimis amounts to the director for his or her income tax purposes. We make tax gross-up payments to reimburse the director for such additional income taxes imposed on the director in these circumstances. The aggregate incremental cost for personal use of our aircraft is calculated based on our variable operating costs, which include crew travel expenses, on-board catering, landing fees, trip-related hangar/parking costs, fuel, trip-related maintenance, and other smaller variable costs. In determining the incremental cost relating to fuel and trip-related maintenance, we applied an estimate derived from our average costs, consistent with the methodology used in prior years. We believe that the use of this methodology for 2025 is a reasonably accurate method for calculating fuel and trip-related maintenance costs. Because our aircraft are used primarily for business travel, we do not include fixed costs that do not change based on usage, such as pilot salaries, our aircraft purchase costs, and the cost of maintenance not related to trips. 

<sup>(c)</sup> These amounts reflect the incremental costs of personal expenses in connection with guests accompanying directors while on business travel and related imputed income to the director for his or her income tax purposes. We make tax gross-up payments to reimburse the director for such additional income taxes imposed on the director in these circumstances.

We make tax gross-up payments to reimburse the director for such additional income taxes imposed on the director in these circumstances.

Item 3 — Ratification of Selection of Independent Registered Public Accountants

## Item 3
Ratification of Selection of Independent Registered Public Accountants

The Audit Committee of the Board of Directors, or Board, has sole authority for the appointment, compensation, and oversight of the work of the independent registered public accountants. The Audit Committee has selected Ernst & Young LLP, or EY, as our independent registered public accountants for the fiscal year ending December 31, 2026, and the Board has directed that management submit this selection for ratification by the stockholders at our 2026 Annual Meeting of Stockholders, or Annual Meeting. EY has served as our independent registered public accounting firm and has audited our financial statements since the Company's inception in 1980. Each year, the Audit Committee evaluates the qualifications and performance of the Company's independent registered public accountants and determines whether to re-engage the current independent registered public accountants or whether there should be a rotation of our independent registered public accountants. In doing so, the Audit Committee considers the quality and efficiency of the services provided by the independent registered public accountants, their technical expertise, knowledge of our complex global operations and industry, the appropriateness of EY's fees, as well as external data on audit quality and performance, including independent assessments by the Public Company Accounting Oversight Board (PCAOB) on EY and its peer firms. Based on this evaluation, the members of the Audit Committee believe that the continued retention of EY as our independent registered public accountants for 2026 is in the best interests of the Company and its stockholders.

In conjunction with the mandated rotation of EY's lead engagement partner, the Audit Committee and its Chair

are directly involved in the selection of EY's new lead engagement partner. The process for selection of EY's lead engagement partner involves a meeting between the Audit Committee's Chair and the candidate, as well as an assessment by the full Audit Committee and management. To ensure a smooth transition, the new lead engagement partner shadows the lead engagement partner and attends Audit Committee meetings in advance of assuming the responsibilities. The selection of a new lead engagement partner most recently occurred in 2021 and was effective after the completion of our 2021 Annual Report on Form 10-K. A representative of EY is expected to be in attendance at the Annual Meeting and will have an opportunity to make a statement and respond to appropriate questions.

Stockholder ratification of the selection of EY as our independent registered public accountants is not required by the Amgen Inc. Restated Certificate of Incorporation, the Amended and Restated Bylaws of Amgen Inc., or otherwise. However, the Board is submitting the selection of EY to our stockholders for ratification because we believe it is a matter of good corporate governance practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain EY but still may retain them. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in our best interests and that of our stockholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" RATIFICATION OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS.

Item 4 — Stockholder Proposal – Independent Board Chairman

## Item 4
Stockholder Proposal – Independent Board Chairman

A stockholder has informed the Company that he intends to present the proposal set forth below at our 2026 Annual Meeting of Stockholders, or Annual Meeting. If the stockholder (or his "qualified representative" as determined under applicable law and our Amended and Restated Bylaws of Amgen Inc., or Bylaws) is in attendance at the Annual Meeting and properly submits the stockholder proposal for a vote, then the stockholder proposal will be voted upon at the Annual Meeting.

The stockholder proposal was submitted by John Chevedden, whose address is 2215 Nelson Ave, #205, Redondo Beach, CA 90278. The number of the Company's securities that the stockholder owns will be provided to stockholders promptly following request.

In accordance with the Federal securities laws, the stockholder proposal and supporting statement is presented below as submitted by the stockholder, quoted verbatim and is in Times New Roman. The Company disclaims all responsibility for the content of the proposal and the supporting statement.

For the reasons stated in the Board of Directors, or Board, response, which follows the stockholder proposal, the Board strongly and unanimously recommends that you vote "AGAINST" the stockholder proposal.

#### Stockholder Proposal:

#### Proposal 4 – Independent Board Chairman
![LOGO](g13946g15a01.jpg)

Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary including the Corporate Governance Guidelines in order that 2 separate people hold the office of the Chairman and the office of the CEO as soon as possible.

The Chairman of the Board shall be an Independent Director. An independent Lead Director shall not be a substitute for an independent Board Chairman.

The Board shall have the discretion to select an interim Chairman of the Board, who is not an Independent Director, to serve while the Board is required to seek an Independent Chairman of the Board on an accelerated basis. This policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition,

An independent Board Chairman improves corporate governance by bringing impartiality, objective oversight, and external expertise to board decisions, mitigating conflicts of interest, enhancing transparency, and boosting shareholder confidence.

This detached perspective allows the chairman to focus on shareholder interests, strengthen management accountability, and provide critical checks and balances.

There was a dispute between AMGN and the proponent of this proposal on whether one page regarding the 2025 version of this proposal was properly submitted to AMGN. The proponent submitted evidence to the Securities and Exchange Commission that the one page was properly submitted to AMGN. This dispute may indicate that AMGN is looking for any technicality to prevent AMGN shareholders from voting on an important shareholder proposal.

Item 4 — Stockholder Proposal – Independent Board Chairman

An independent Board Chairman could also help Amgen (AMGN) deal with headwinds like those that emerged in 2025:

Patents for top-selling drugs Prolia<sup>®</sup> and Xgeva<sup>®</sup> expired in the U.S. in February 2025. This led to biosimilars launching in the U.S. market and has already caused sales erosion for Xgeva and is expected to result in significant sales declines for both Prolia and Xgeva in the latter half of 2025 and into 2026.

Amgen recorded a $400 million intangible asset impairment charge in Q3 2025 related to Otezla psoriasis. This was tied to U.S. government price negotiations under the Inflation Reduction Act, following an $800 million charge for the same issue earlier in 2025.

Across its portfolio, AMGN continues to face a negative impact from lower net selling prices and pricing headwinds.

AMGN stock experienced a decline following concerns about the tolerability of its promising weight-loss drug candidate, MariTide.

Enbrel (etanercept) sales decreased significantly (30% year-over-year in Q3 2025), driven by lower net selling prices due to increased 340B Program mix and the impact of the U.S. Medicare Part D redesign.

AMGN continues to carry a high debt-to-equity ratio, and there has been notable negative insider reaction indicated by increased AMGN insider stock sales throughout 2025, which may signal AMGN insider caution about future AMGN prospects.

Please vote yes:

#### Independent Board Chairman – Proposal 4
Board Response to Item 4: Stockholder Proposal – Independent Board Chairman

The Board of Directors recommends a vote "AGAINST" the Stockholder Proposal.

Our Board of Directors has considered this proposal and has concluded that it is not in the best interests of the Company or its stockholders to prohibit the Chief Executive Officer, or CEO, of the Company from serving as the Chairman and mandate that the Chairman be an independent director, as broadly defined by the proponent.

The Board's recommendation to vote "AGAINST" the Stockholder Proposal is based on the following reasons:

The Company's governance documents give the Board discretion in determining whether to separate or combine the roles of the Chairman and CEO. This flexibility permits the Board to choose a leadership structure that can be tailored to the strengths of the Company's officers and directors and to best address the Company's evolving and highly complex business. The Board conducts annual evaluations of the Company's leadership structure and determined that the Company and its stockholders are best served at this time by having Robert A. Bradway serve as both Chairman and CEO, coupled by a separate active lead independent director (currently served by Robert A. Eckert) for the following reasons:

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Bradway is most familiar with our business and the unique challenges we face. Mr. Bradway's day-to-day insight into our challenges facilitates a timely deliberation by the Board of important matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Bradway has and will continue to identify agenda items important for the Board's understanding and oversight and lead effective discussions on the important matters affecting our business, prospects and results. Mr. Bradway's knowledge and extensive experience regarding our operations and the highly regulated industries and markets in which we compete position him to identify and prioritize matters for Board review and deliberation.

&nbsp;&nbsp;&nbsp;&nbsp;• As Chairman and CEO, Mr. Bradway serves as an important bridge between the Board and management and provides critical leadership for carrying out our strategic initiatives and confronting our challenges. The Board believes that Mr. Bradway brings a unique, stockholder-focused insight to assist the Company to most effectively execute its strategy and business plans to maximize stockholder value.

&nbsp;&nbsp;&nbsp;&nbsp;• The strength and effectiveness of the communications between Mr. Bradway as our Chairman and Mr. Eckert as our lead independent director result in comprehensive Board oversight of the issues, plans, and prospects of our Company.

&nbsp;&nbsp;&nbsp;&nbsp;• This leadership structure provides the Board with more complete and timely information about the Company, a unified structure and consistent leadership direction internally and externally and provides a collaborative and collegial environment for Board decision making.

**Annual Assessment.** The Board reviews the Company's leadership structure on an annual basis and reserves the right to separate the role of the Chairman and CEO at any time.

Item 4 — Stockholder Proposal – Independent Board Chairman

Mechanisms to Ensure Independent Oversight. Our Board's oversight and evaluation of the CEO and other senior management are not limited by having a current or former executive serving as Chairman. We have numerous mechanisms in place that ensure independent oversight of the Company's affairs and that facilitate communication with, and independent evaluation of, senior management, including:

&nbsp;&nbsp;&nbsp;&nbsp;• Active Experienced Lead Independent Director with Robust Responsibilities. We have an active "lead independent director" elected annually by and from the independent directors and strong Board and committee involvement to provide sound and robust oversight of management. Mr. Eckert currently serves as the lead independent director, a position he has held since 2016. His robust set of duties and authority are described in detail under "Corporate Governance—Board Leadership Structure." This leadership structure provides a means for regular dialogue among our independent directors, ensures an effective bridge between independent directors and Mr. Bradway and provides a channel through which independent directors may raise and elevate significant concerns to management. Key responsibilities of our lead independent director include:

&nbsp;&nbsp;&nbsp;&nbsp;• Approving meeting agendas for the Board;

&nbsp;&nbsp;&nbsp;&nbsp;• Assuring that there is sufficient time for discussion of all meeting agenda items;

&nbsp;&nbsp;&nbsp;&nbsp;• Previewing the information to be provided to the Board;

&nbsp;&nbsp;&nbsp;&nbsp;• Having the authority to call meetings of the independent directors;

&nbsp;&nbsp;&nbsp;&nbsp;• Organizing and leading the Board's evaluation of the CEO;

&nbsp;&nbsp;&nbsp;&nbsp;• Serving as a liaison between the Chairman and the independent directors;

&nbsp;&nbsp;&nbsp;&nbsp;• Leading the Board's annual self-evaluation;

&nbsp;&nbsp;&nbsp;&nbsp;• Ensuring that he/she is available for consultation and direct communication, if requested by major stockholders; and

&nbsp;&nbsp;&nbsp;&nbsp;• Presiding at meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors.

&nbsp;&nbsp;&nbsp;&nbsp;• In addition to the responsibilities outlined above, the lead independent director also:

&nbsp;&nbsp;&nbsp;&nbsp;• Meets with the Chairman prior to each regular meeting of the Board and its committees to discuss, provide input on, and approve the agendas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;• With the Chairman, determines who attends Board meetings, such as members of management or outside advisors, and presenters;

&nbsp;&nbsp;&nbsp;&nbsp;• Has one-on-one discussions with each independent director, including as part of the Board's annual self-evaluation process;

&nbsp;&nbsp;&nbsp;&nbsp;• At his discretion, attends committee meetings, including those committees for which he/she is not a member, and has access to all committee materials;

&nbsp;&nbsp;&nbsp;&nbsp;• Attends significant management events (such as our annual executive director and officer's meeting at which we align around the Company's priorities for the year), providing opportunities for leadership effectiveness assessments;

&nbsp;&nbsp;&nbsp;&nbsp;• Has the authority to engage independent consultants;

&nbsp;&nbsp;&nbsp;&nbsp;• Is regularly apprised of inquiries from stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;• Interviews Board candidates; and

&nbsp;&nbsp;&nbsp;&nbsp;• Has an increased role in crisis and risk management, as appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;• Regular Communications. The lead independent director engages in regular communication between the independent directors and Mr. Bradway, keeping Mr. Bradway apprised of any concerns, issues, or determinations made during the independent sessions, and consults with Mr. Bradway on other matters pertinent to the Company and the Board.

&nbsp;&nbsp;&nbsp;&nbsp;• Independent Board. We have diverse, experienced, and skilled directors. Eleven of our twelve director nominees (92%) are independent as defined by The NASDAQ Stock Market listing standards and the requirements of the Securities and Exchange Commission, with Mr. Bradway, our CEO, representing the sole exception.

&nbsp;&nbsp;&nbsp;&nbsp;• Independent Committee Leadership. We have strong Board and committee involvement to provide sound and robust oversight of management. All members of the Board's key committees (Audit, Compensation and Management Development, Corporate Responsibility and Compliance, and Governance and Nominating) are independent. In addition:

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee chair meets with management to review and refine agenda, add topics of interest, and review and comment on materials to be delivered to the committee;

&nbsp;&nbsp;&nbsp;&nbsp;• Every independent director has access to all committee materials;

ï *2026 Proxy Statement*115

------

##### [**Table of Contents**](#toc)
Item 4 — Stockholder Proposal – Independent Board Chairman

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee chair provides a report summarizing committee meetings to the full Board at each regular meeting of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee meeting includes adequate time for executive session and the committees meet in executive session on a regular basis with no members of management present (unless otherwise requested by the committee); and

&nbsp;&nbsp;&nbsp;&nbsp;• Each committee effectively manages its Board-delegated duties and communicates regularly with the Chairman and members of management.

&nbsp;&nbsp;&nbsp;&nbsp;• Independent Directors Sessions. A meeting of the independent directors is scheduled at every regular Board meeting and the independent directors meet in an executive session without Mr. Bradway to review Company performance, management effectiveness, proposed programs and transactions, and the Board meeting agenda items. These independent sessions are organized and chaired by our lead independent director and our lead independent director provides direct feedback to Mr. Bradway after these executive sessions.

&nbsp;&nbsp;&nbsp;&nbsp;• Stockholder Engagement. Each year, we reach out to stockholders representing approximately 50% of our outstanding shares so that we are fully informed and able to carefully weigh the views of our stockholders. During our stockholder engagement discussions, many of our stockholders have expressed support and confidence in our current governance structure. We have a long history of proactively responding to stockholder concerns and have strong stockholder rights, including proxy access, a majority voting policy for director elections, and providing stockholders the right to call special meetings of stockholders and act by written consent. Stockholders may also communicate with our Board directly as described on page 28.

Strong 2025 Performance Under the Board's Leadership Structure. In 2025, despite the headwinds cited in the proposal as a rationale for changing the Board's leadership structure, the Company delivered strong performance and robust financial results, including 10% year-over-year revenue and sales growth, with 18 products achieving record sales, 14 products exceeding $1 billion in sales, and 13 products delivering double-digit sales growth, and made meaningful progress on our strategic priorities, including advancing our innovative pipeline and securing five U.S. Food and Drug Administration approvals. Our strong cash flows and balance sheet in 2025 allowed us to make significant

investments for long-term growth, including investing approximately $7 billion in research and development and $2 billion in strategic capital projects, while also reducing our debt outstanding by $6 billion and returning $5 billion of capital to our stockholders in dividends (including a 6% year-over-year increase in our quarterly dividend per share). Our performance in 2025 demonstrated the effectiveness of our Board leadership structure and its oversight of the Company's strategy and execution.

Commitment to Stockholder Rights. We maintain meaningful stockholder rights and regularly review our corporate governance practices with the Board in light of investor feedback and evolving market practices. These stockholder rights include the following:

&nbsp;&nbsp;&nbsp;&nbsp;• Single Class of Shares. We have a single class of shares with equal voting rights. One share equals one vote.

&nbsp;&nbsp;&nbsp;&nbsp;• Proxy Access. Our Bylaws permit proxy access for director nominations. Eligible stockholders with an ownership threshold of 3% who have held their shares for at least 3 years and who otherwise meet the requirements set forth in our Bylaws may have their nominees up to the number of directors constituting the greater of 20% of the total number of directors or two nominees of our Board included in our proxy materials. Up to 20 eligible stockholders may group together to reach the 3% ownership threshold. In the course of designing our proxy access provisions, we carefully considered each element in the interest of our stockholders as a whole, including that the number of stockholders who may group together (20) would afford those stockholders likely to utilize proxy access with the opportunity to do so.

&nbsp;&nbsp;&nbsp;&nbsp;• Action by Written Consent. Our Amgen Inc. Restated Certificate of Incorporation permits stockholders to act by written consent in lieu of a meeting upon the request of the holders of at least 15% of our outstanding common shares who otherwise meet the requirements of our Certificate of Incorporation.

&nbsp;&nbsp;&nbsp;&nbsp;• Special Meetings . Our Bylaws permit stockholders to request that the Company call a special meeting upon the written request of the holders of at least 15% of our outstanding common shares who otherwise meet the requirements set forth in our Bylaws.

&nbsp;&nbsp;&nbsp;&nbsp;• No Supermajority Vote Provisions. We have a simple majority voting standard to amend our Certificate of Incorporation and Bylaws.

&nbsp;&nbsp;&nbsp;&nbsp;• No Poison Pill. We do not have a shareholder rights plan, or poison pill.

Item 4 — Stockholder Proposal – Independent Board Chairman

Given the Company's focus on stockholder rights, strong financial performance, independent Board structure, the comprehensive role of the lead independent director and other strong corporate governance practices, the Board believes that mandated separation of the positions of Chairman and CEO would weaken the Company's current leadership structure. The proposal would also

deprive the Board of the valuable flexibility to exercise its business judgment in selecting the individual best suited to serve as Chairman in the future. Therefore, the Board does not believe that implementing the proposal would be in the best interests of the Company or its stockholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "AGAINST" THE STOCKHOLDER PROPOSAL – INDEPENDENT BOARD CHAIRMAN.

Audit Matters

## Audit Matters
Audit Committee Report

The Audit Committee has reviewed and discussed with management the Company's audited consolidated financial statements as of and for the year ended December 31, 2025.

The Audit Committee has also discussed with Ernst & Young LLP, or EY, the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the Securities and Exchange Commission.

The Audit Committee has received and reviewed the written disclosures and the letter from EY required by the

applicable requirements of the PCAOB regarding EY's communication with the Audit Committee concerning independence and has discussed with EY their independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements referred to above be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the Securities and Exchange Commission.

The following table presents fees for professional services provided or to be provided by EY for audits of the years ended December 31, 2025 and December 31, 2024, and fees for other services rendered by EY during these periods.

| | | |
|:---|:---|:---|
| | 2025 | 2024 |
|  Audit Fees | $14593000 | $13657000 |

|  Tax Fees | 0 | 0 |
|  All Other Fees | 260000 | 0 |
|  Total Fees | $15369000 | $14345000 |

---

Included in Audit fees above are professional services associated with the integrated audit of our consolidated financial statements and our internal controls over financial reporting and the statutory audits of various subsidiaries of the Company. Audit-Related fees are attributable to assurance and related services that are also performed by our independent registered public accountants, including attest related services, accounting consultations, and audits of employee benefit plan information. All Other Fees include system pre-implementation review services. The Audit Committee has considered whether the Audit-Related

and non-audit services provided by EY are compatible with maintaining that firm's independence.

The Audit Committee has approved all audit and permissible non-audit services prior to such services being provided by EY. The Audit Committee, or the Chair of the Audit Committee who has been granted authority by the Audit Committee, approves each audit or non-audit service prior to the engagement of EY for such service. Each such service approved by the Chair of the Audit Committee is presented to the entire Audit Committee at a subsequent meeting.

Certain Relationships and Related Transactions

## Certain Relationships and Related Transactions
Under our written Approval of Related Party Transactions policy, a SEC Related Party Transaction (as defined below) may be consummated or may continue only if the Audit Committee approves or ratifies the transaction in accordance with the guidelines set forth in the policy. The policy applies to: (1) any person who is, or at any time since the beginning of our last fiscal year was, a member of our Board of Directors, or Board, one of our executive officers or a nominee to become a member of our Board; (2) any person who is known to be the beneficial owner of more than 5% of any class of our voting securities; (3) any immediate family member, as defined in the policy, of, or sharing a household with, any of the foregoing persons; and (4) any firm, corporation or other entity in which any of the foregoing persons is employed, or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest.

A "SEC Related Party Transaction" is defined in the policy as a transaction, arrangement or relationship, or series of similar transactions, arrangements or relationships (including but not limited to any indebtedness or guarantee of indebtedness) between us and any of the persons listed in the first paragraph of this section. A related party transaction also includes any material amendment or modification to an existing related party transaction. All potential related party transactions are presented to the Audit Committee for its consideration and, if the Audit Committee deems it appropriate, approval. The Audit Committee considers all relevant facts and circumstances available to it, including the recommendation of management. No member of the Audit Committee participates in any review, consideration, or approval of any related party transaction involving such member or any of his or her immediate family members, except that such member is required to provide all material information concerning the related party transaction to the Audit Committee.

Related party transactions may be preliminarily entered into by management subject to ratification by the Audit Committee; provided that if ratification shall not be forthcoming, management shall make all reasonable efforts to cancel or annul such transaction. At each scheduled meeting of the Audit Committee, management is required to update the Audit

Committee as to any material changes to any approved or ratified related party transaction. The Audit Committee has excluded each of the following related party transactions under the terms of our Approval of Related Party Transactions policy:

&nbsp;&nbsp;&nbsp;&nbsp;1. Any matters related to compensation or benefits to the extent such compensation or benefits would not be required to be disclosed under Item 404 of Regulation S-K under the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;2. Transactions involving less than $120,000 (or such different amount as may require disclosure or approval under any future amendment to the rules and regulations of the SEC, including Item 404 of Regulation S-K, or the listing requirements of The NASDAQ Stock Market LLC, including Rule 5630) when aggregated with all similar transactions; or

&nbsp;&nbsp;&nbsp;&nbsp;3. Transactions approved by another independent committee of the Board.

In deciding whether to approve or ratify a related party transaction, the Audit Committee will consider the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;• Whether the terms of the transaction are (i) fair to the Company and (ii) at least as favorable to the Company as would apply if the transaction did not involve a related party;

&nbsp;&nbsp;&nbsp;&nbsp;• Whether there are demonstrable business reasons for the Company to enter into the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;• Whether the transaction would impair the independence of an outside director; and

&nbsp;&nbsp;&nbsp;&nbsp;• Whether the transaction would present an improper conflict of interest for any director or executive officer, taking into account the size of the transaction, the overall financial position of the related party, the direct or indirect nature of the related party's interest in the transaction and the ongoing nature of any proposed relationship, and any other factors the Audit Committee deems relevant.

Separately, to avoid even the appearance of a conflict of interest related to service on our Board, we require appropriate reporting of service in scientific publications and presentations.

Certain Relationships and Related Transactions

Transactions with Related Persons

Dr. Leandro Grimaldi, who is the son-in-law of Nancy A. Grygiel, an executive officer of the Company, is employed by us as Business Performance Director. Dr. Grimaldi's compensation earned in 2025 consisted of $240,000 in base salary, $78,810 in annual cash incentive award, and grants of restricted stock units and performance units valued at $54,000 on the grant date.

Dr. Grimaldi also participates in the Company's employee benefits programs. This transaction did not require the review or approval of the Audit Committee pursuant to our Approval of Related Party Transactions policy because it was approved by our Compensation and Management Development Committee in 2021 prior to Dr. Grimaldi's hiring.

Information Concerning Voting and Solicitation

#### Difference Between a Stockholder of Record and a "Street Name" Holder
If your shares are registered directly in your name in the records of the Company's transfer agent, you are considered the stockholder of record with respect to those shares.

If your shares are held in a stock brokerage account or by a bank, trust, or other nominee, then the broker, bank, trust, or other nominee is considered to be the stockholder of record with respect to those shares. However, you are still considered to be the beneficial owner of those shares, and your shares are said to be held in "street name." Street name holders generally cannot submit a proxy or vote their shares directly and must instead instruct the broker, bank, trust, or other nominee how to vote their shares using the methods described below under "Voting Your Shares."

#### Shares Outstanding and Quorum
At the close of business on March 20, 2026, there were 539,685,503 shares of our Common Stock outstanding and entitled to vote at the Annual Meeting. The presence of the holders of a majority of the outstanding shares of our Common Stock entitled to vote constitutes a quorum, which is required to hold and conduct business at the Annual Meeting. Shares are counted as present at the Annual Meeting if:

&nbsp;&nbsp;&nbsp;&nbsp;• You are in attendance at the Annual Meeting; or

&nbsp;&nbsp;&nbsp;&nbsp;• Your shares are represented by a properly authorized and submitted proxy (submitted by mail, by telephone, or over the internet).

If you are a record holder and you submit your proxy, regardless of whether you abstain from voting on one or more matters, your shares will be counted as present at the Annual Meeting for the purpose of determining a quorum. If your shares are held in "street name," your shares are counted as present for purposes of determining a quorum if your broker, bank, trust, or other nominee submits a proxy covering your shares. Your broker, bank, trust, or other nominee is entitled to submit a proxy covering your shares as to certain "routine" matters, even if you have not instructed your broker, bank, trust, or other nominee on how to vote on those matters. Please see the subsection "If You Do Not Specify How You Want Your Shares Voted" below. In the absence of a quorum, the Annual Meeting may be adjourned, from time to time, by the Chair of the meeting or by the vote of the holders of a majority of the shares represented thereat, but no other business shall be transacted at such meeting.

#### Voting Your Shares
You may vote by attending the Annual Meeting and voting or by submitting a proxy. The method of voting by proxy differs (1) depending on whether you are viewing this proxy statement on the internet or receiving a paper copy and (2) for shares held as a record holder and shares held in "street name."

Shares Held as a Record Holder. If you hold your shares of Common Stock as a record holder and you are viewing this proxy statement on the internet, you may submit a proxy over the internet by following the instructions on the website referred to in the Notice previously mailed to you. You will need your control number (contained on your Notice) to submit your proxy over the internet. You may request paper copies of the proxy statement and proxy card by following the instructions on the Notice. If you hold your shares of Common Stock as a record holder and you are reviewing a paper copy of this proxy statement, you may submit a proxy over the internet or by telephone by following the instructions on the proxy card, or by completing, dating, and signing the proxy card that was included with the proxy statement and promptly returning it in the pre-addressed, postage-paid envelope provided to you. You will need your control number (contained on your Notice) to submit your proxy over the internet or over the telephone.

Shares Held in Street Name. If you hold your shares of Common Stock in street name, you will receive a Notice from your broker, bank, trust, or other nominee that includes instructions on how to vote your shares. Your broker, bank, trust, or other nominee may allow you to deliver your voting instructions over the internet and may also permit you to submit your voting instructions by telephone. In addition, you may request paper copies of the proxy statement and proxy card from your broker by following the instructions on the Notice provided by your broker, bank, trust, or other nominee.

The internet<sup>(1)</sup> and telephone voting facilities will close at 11:59 P.M., Eastern Time, on May 18, 2026. Stockholders who submit a proxy by internet or telephone need not return a proxy card or the form forwarded by your broker, bank, trust, or other holder of record by mail.

YOUR VOTE IS VERY IMPORTANT.

You should submit your proxy even if you plan to

attend the Annual Meeting.

#### Voting at the Annual Meeting
As discussed previously, our Annual Meeting will be held solely by remote communication via the internet at www.virtualshareholdermeeting.com/AMGN2026.

<sup>(1)</sup> Stockholders who submit a proxy through the internet or telephone should be aware that they may incur costs to access the internet or telephone, such as usage charges from telephone companies or internet service providers and that these costs must be borne by the stockholder.

Information Concerning Voting and Solicitation

Although the meeting will not be held in person, stockholders will, to the extent possible, be afforded the same rights and opportunities to participate at the virtual meeting similarly to how they would participate at an in-person meeting. To participate and vote at the Annual Meeting, you will need to log-in to www.virtualshare holdermeeting.com/AMGN2026 using the control number on the Notice, proxy card, or voting instruction form. Please note that if your shares are held in street name (by a broker, bank, trust, or other nominee), and you decide to attend and vote at the Annual Meeting, your vote while in attendance at the Annual Meeting will not be effective unless you provide a legal proxy, issued in your name from the record holder (your broker, bank, trust, or other nominee). **Even if you intend to attend the Annual Meeting, we encourage you to submit your proxy in advance of the Annual Meeting.** Please see the important instructions and requirements below regarding "Attendance at the Annual Meeting."

To vote at the Annual Meeting, visit www.virtualshare holdermeeting.com/AMGN2026. For shares held as a record holder <u>or</u> in street name, you will need the control number that appears on your Notice, proxy card, or voting instruction form.

#### Changing Your Vote
As a stockholder of record, if you submit a proxy, you may revoke that proxy at any time before it is voted at the Annual Meeting. Stockholders of record may revoke a proxy by (i) duly submitting a later-dated proxy over the internet, by mail, or by telephone, (ii) delivering a written notice of revocation to the attention of the Secretary at our principal executive offices at One Amgen Center Drive, Thousand Oaks, California 91320-1799, or (iii) attending the Annual Meeting and voting at the Annual Meeting. Attendance at the Annual Meeting will not, by itself, revoke a proxy. If your shares are held in the name of a broker, bank, trust, or other nominee, you may change your voting instructions by following the instructions of your broker, bank, trust, or other nominee.

#### If You Receive More Than One Proxy Card or Notice
If you receive more than one proxy card or Notice, it means you hold shares that are registered in more than one account. To ensure that all your shares are voted, sign and return each proxy card or, if you submit a proxy by telephone or the internet, submit one proxy for each proxy card or Notice you receive.

#### How Will Your Shares Be Voted
Stockholders of record as of the close of business on March 20, 2026, are entitled to one vote for each share of

our Common Stock held on all matters to be voted upon at the Annual Meeting. All shares entitled to vote and represented by properly submitted proxies received before the polls are closed at the Annual Meeting, and not revoked or superseded, will be voted at the Annual Meeting in accordance with the instructions indicated on those proxies. **YOUR VOTE IS VERY IMPORTANT**.

#### If You Do Not Specify How You Want Your Shares Voted
As a stockholder of record, if you submit a signed proxy card or submit your proxy by telephone or internet and do not specify how you want your shares voted, the proxy holder will vote your shares:

&nbsp;&nbsp;&nbsp;&nbsp;• FOR the election of the 12 nominees listed in this proxy statement to serve on our Board for a term of office expiring at the 2026 annual meeting of stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;• FOR the advisory vote to approve our executive compensation;

&nbsp;&nbsp;&nbsp;&nbsp;• FOR the ratification of the selection of Ernst & Young LLP as our independent registered public accountants for the fiscal year ending December 31, 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;• AGAINST the stockholder proposal—Independent Board Chairman.

A "broker non-vote" occurs when a nominee holding shares for a beneficial owner has not received voting instructions from the beneficial owner and the nominee does not have discretionary authority to vote the shares on that proposal. If you hold your shares in street name and do not provide voting instructions to your broker or other nominee, your shares will be considered to be broker non-votes and will not be voted on any proposal on which your broker or other nominee does not have discretionary authority to vote. Shares that constitute broker non-votes will be counted as present at the Annual Meeting for the purpose of determining a quorum but will not be considered entitled to vote on the proposal in question and therefore will have no effect on the outcome of the vote. Brokers generally have discretionary authority to vote on the ratification of the selection of Ernst & Young LLP as our independent registered public accountants, and thus broker non-votes are not likely on these proposals. Brokers, however, do not have discretionary authority to vote on (i) the election of directors to serve on our Board, (ii) the advisory vote to approve our executive compensation, or (iii) the stockholder proposal. Accordingly, broker non-votes will likely result on these proposals.

In their discretion, the proxy holders named in the proxy solicited by the Company are authorized to vote the proxies in their discretion on any other matters that may

**124** ï *2026 Proxy Statement* 

------

##### [**Table of Contents**](#toc)
Information Concerning Voting and Solicitation

properly come before the Annual Meeting and any continuation, postponement, or adjournment thereof. The Board knows of no other items of business that will be presented for consideration at the Annual Meeting other than those described in this proxy statement. In addition, no stockholder nomination was received on a timely basis, so no such matter may be brought to a vote at the Annual Meeting.

#### Inspector of Election and Counting of Votes
All votes will be tabulated as required by Delaware law, the state of our incorporation, by the inspector of election appointed for the Annual Meeting, who will separately tabulate affirmative and negative votes, abstentions, and broker non-votes. Shares held by persons attending the Annual Meeting but not voting, shares represented by proxies that reflect abstentions as to one or more proposals, and broker non-votes will be counted as present for purposes of determining a quorum.

Election of Directors. We have a majority voting standard for the election of directors in an uncontested election, which is generally defined as an election in which the number of nominees does not exceed the number of directors to be elected at the meeting. In the election of directors, you may either vote "for," "against," or "abstain" for each nominee. Cumulative voting is not permitted. Under our majority vote standard, in uncontested elections of directors, such as this election, each director must be elected by the affirmative vote of a majority of the votes cast by the shares in attendance at the Annual Meeting or represented by proxy. A "majority of the votes cast" means that the number of votes cast "for" a director nominee exceeds the number of votes cast "against" the nominee. For these purposes, abstentions and broker non-votes will not count as a vote "for" or "against" a nominee's election and thus will have no effect in determining whether a director nominee has received a majority of the votes cast. Brokers do not have discretionary authority to vote on this proposal. If a director nominee is an incumbent director and does not receive a majority of the votes cast in an uncontested election, that director will continue to serve on the Board as a "holdover" director, but must tender his or her resignation (contingent upon acceptance by the Board) to the Board promptly after certification of the election results of the stockholder vote. The Governance and Nominating Committee of the Board will then recommend to the Board whether to accept the resignation or whether other action should be taken. The Board will act on the tendered resignation, taking into account the recommendation of the Governance and Nominating Committee, and the Board's decision will be

publicly disclosed within 90 days after certification of the election results of the stockholder vote. A director who tenders his or her resignation after failing to receive a majority of the votes cast will not participate in the recommendation of the Governance and Nominating Committee or the decision of the Board with respect to his or her resignation.

Management Proposals (Advisory Vote to Approve Our Executive Compensation and Ratification of Ernst & Young LLP) and Stockholder Proposal. The approval of the advisory vote to approve our executive compensation, the ratification of the selection of Ernst & Young LLP, and the stockholder proposal require the affirmative votes of the holders of a majority of the shares present or represented by proxy at the Annual Meeting and entitled to vote on the matter. Abstentions will have the same effect as votes "against" each proposal.

Because brokers have discretionary authority to vote on the ratification of the selection of Ernst & Young LLP, we do not expect any broker non-votes in connection with the ratification (and any broker non-votes received will have no effect on such ratification proposal). Brokers do not have discretionary authority to vote on the advisory vote to approve our executive compensation or the stockholder proposal. Broker non-votes, therefore, will have no effect on the advisory vote to approve our executive compensation or the stockholder proposal as brokers are not entitled to vote on such proposal in the absence of voting instructions from the beneficial owner.

#### Solicitation of Proxies
We will bear the entire cost of solicitation of proxies, including preparation, assembly, and mailing of this proxy statement, the proxy card, the Notice, and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries, and custodians holding shares of our Common Stock in their names that are beneficially owned by others to forward to those beneficial owners. We may reimburse persons representing beneficial owners for their costs of forwarding the solicitation materials to the beneficial owners. Original solicitation of proxies may be supplemented by telephone, facsimile, electronic mail, or personal solicitation by our directors, officers, or staff members. No additional compensation will be paid to our directors, officers, or staff members for such services. In addition, we have retained D.F. King & Co. to assist in the solicitation of proxies for a fee of approximately $100,000 plus distribution costs and other costs and expenses. A list of stockholders entitled to vote at the Annual Meeting will be available upon request to our

Our Amended and Restated Bylaws of Amgen Inc., or Bylaws, permit an eligible stockholder, or group of up to 20 eligible stockholders, owning Amgen stock continuously for at least three years and shares representing an aggregate of at least 3% of our outstanding shares, to nominate and include in Amgen's proxy materials director nominees constituting up to the greater of 20% of the Board or two directors, provided that the stockholder(s) and nominee(s) satisfy the requirements of the Bylaws ("Proxy Access"). To nominate a director pursuant to Proxy Access at the 2027 annual meeting of stockholders, you must comply with all of the procedures, information requirements, qualifications and conditions set forth in our Bylaws. A fully compliant nomination notice must be received by us no earlier than November 8, 2026, and no later than December 8, 2026, assuming the date of the 2027 annual meeting of stockholders is not more than thirty days before and not more than seventy days after the anniversary date of the 2026 Annual Meeting of Stockholders, or Annual Meeting, and such nomination notice must be delivered to our Secretary at our principal executive offices at One Amgen Center Drive, Thousand Oaks, California 91320-1799 or by facsimile number (805) 855-4002.

#### Stockholder Proposals and Nominees Brought at the 2027 Annual Meeting Without Inclusion in our 2027 Proxy Statement
Business Proposals and Nominations Pursuant to our Bylaws. To nominate a director or bring any other

business before the stockholders at the 2027 annual meeting of stockholders that will not be included in our 2027 proxy statement pursuant to Rule 14a-8 or the Proxy Access provisions of our Bylaws, you must comply with all of the procedures, information requirements, qualifications, and conditions set forth in our Bylaws. In addition, assuming the date of the 2027 annual meeting of stockholders is not more than thirty days before and not more than seventy days after the anniversary date of the Annual Meeting, you must notify us in writing and such notice must be delivered to our Secretary at our principal executive offices at One Amgen Center Drive, Thousand Oaks, California 91320-1799 or by facsimile number (805) 855-4002 no earlier than January 19, 2027, and no later than February 18, 2027.

You may write to our Secretary at our principal executive offices at One Amgen Center Drive, Thousand Oaks, California 91320-1799 or by facsimile number (805) 855-4002, to deliver the notices discussed above and for a copy of the relevant Bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates pursuant to our Bylaws. Also, our Bylaws are filed with the SEC as an exhibit to our Exchange Act reports and can be accessed through the SEC's EDGAR system.

The Chair of the Annual Meeting has the authority to determine whether any nomination or other proposal has been properly brought before the meeting in accordance with our Bylaws. If we receive a proposal other than pursuant to Rule 14a-8 or a nomination for the 2027 annual meeting of stockholders, and such nomination or other proposal is not delivered within the time frame specified in our Bylaws, then the person(s) appointed by the Board and named in the proxies for the 2027 annual meeting of stockholders may exercise discretionary voting power if a vote is taken with respect to that nomination or other proposal.

In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 22, 2027.

#### 2027 Annual Meeting
We intend to file a Proxy Statement and WHITE proxy card with the SEC in connection with our solicitation of proxies

Other Matters

for our 2027 annual meeting of stockholders. Stockholders may obtain our Proxy Statement (and any amendments and supplements thereto) and other documents as and

when filed by the Company with the SEC without charge from the SEC's website at: www.sec.gov.<sup>(1)</sup>

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (such as brokers and banks) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as "householding," is also permissible under the General Corporation Law of the State of Delaware and potentially means extra convenience for stockholders and cost savings for companies.

A number of brokers and banks with account holders who are our stockholders will be householding our proxy materials. A single Notice of Annual Meeting of Stockholders or proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker or bank that it will be householding

communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, please notify your broker or bank. If you currently receive multiple copies of the proxy statement at your address from your broker or bank and would like to request householding of their communications, please contact your broker or bank.

Stockholders of record who currently receive multiple copies of the proxy statement at their address and would like to request householding, or who wish to discontinue householding and receive separate copies of the proxy statement, should contact Investor Relations, One Amgen Center Drive, Thousand Oaks, California 91320-1799, or by telephone at (805) 447-1060 or email at investor.relations@amgen.com.

No Incorporation by Reference

To the extent that this proxy statement is incorporated by reference into any other filing by us under the Securities Act of 1933 or the Exchange Act, the sections of this proxy statement entitled "Compensation Committee Report," "Pay Versus Performance," or "Audit Committee Report," to the extent permitted by the rules of the SEC, will not be deemed incorporated, unless specifically provided otherwise in such filing.

Information on our website, other than our proxy statement, Notice of Annual Meeting of Stockholders, and form of proxy, is not part of the proxy soliciting material and is not incorporated herein by reference.

Disclaimer

This proxy statement contains statements regarding future individual and Company performance targets and Company performance goals. These targets and Company performance goals are disclosed in the limited context of our compensation programs and should not

be understood to be statements of management's expectations or estimates of results or other guidance. We specifically caution investors not to apply these statements to other contexts.

Forward-Looking Statements

This proxy statement contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeOne Medicines Ltd.), the performance of Otezla<sup>®</sup> (apremilast), our acquisitions of ChemoCentryx, Inc., Dark Blue Therapeutics, Ltd. or Horizon Therapeutics plc (including the prospective performance and outlook of Horizon's business, performance and opportunities, and any potential strategic benefits, synergies or opportunities expected as a result of such acquisition), as well as estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes, effects of pandemics or other widespread health problems on our business, outcomes, progress, and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this proxy statement and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions, including those resulting from geopolitical relations and government actions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing,

marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. An outbreak of disease or similar public health threat, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to collaborate with or acquire

ï *2026 Proxy Statement*129

Other Matters

other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful, and may result in unanticipated costs, delays or failures to realize the benefits of the transactions. A breakdown, cyberattack or information security breach of our information technology systems could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Our business and operations may be negatively affected by the failure, or

perceived failure, of achieving our sustainability objectives. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.

Other Matters

The Board knows of no matters other than those listed in the attached Notice of Annual Meeting of Stockholders that are likely to be brought before the Annual Meeting. However, if any other matter properly comes before the Annual Meeting, the persons named on the enclosed proxy card will vote the proxy in accordance with their best judgment on such matter.

## Appendix A

## Amgen Inc. Board of Directors

## Guidelines for Director Qualifications and Evaluations
These guidelines set forth (1) the minimum qualifications that the Governance and Nominating Committee of the Board of Directors (the "Committee") of Amgen Inc. ("Amgen") believes are important for directors to possess, and (2) a description of the Committee's process for identifying and evaluating nominees for director, including nominees recommended by stockholders. These guidelines are only guidelines and may be waived and/or changed by the Committee and/or the Board of Directors as appropriate.

1. Candidate Qualifications

In seeking individuals to join the Board of Directors or to fill director vacancies on the Board of Directors, the Committee considers the following to be minimum qualifications that a candidate must possess:

• Demonstrated breadth and depth of management and leadership experience, preferably in a senior leadership role in a large or recognized organization;

• Financial and/or business acumen or relevant industry or scientific experience;

• Integrity and high ethical standards;

• Sufficient time to devote to Amgen's business as a member of the Board;

• Ability to oversee, as a director, Amgen's business and affairs for the benefit of Amgen's stockholders;

• Ability to comply with the Board's Code of Conduct; and

• Demonstrated ability to think independently and work collaboratively.

In addition, the Committee may consider the following where necessary and appropriate:

• A candidate's independence, as defined by The NASDAQ Stock Market, Inc.;

• A candidate's ability to satisfy the composition requirements for the Audit Committee and the Compensation and Management Development Committee;

• Maintaining a Board that reflects diversity; and

• The Board's overall size, structure and composition.

2. Candidate Identification and Evaluation Process

(a) For purposes of identifying nominees for the Board of Directors, the Committee relies on professional and personal contacts of the Committee, other members of the Board of Directors and senior management, as well as candidates recommended by independent search firms retained by the Committee from time to time. The Committee also will consider candidates recommended by stockholders. Any director nominations submitted by stockholders will be evaluated in the same manner that nominees suggested by Board members, management or other parties are evaluated.

(b) In evaluating potential candidates, the Committee will determine whether the candidate is qualified for service on the Board of Directors by evaluating the candidate under the guidelines set forth above and by determining if any individual candidate suits the Committee's and the Board of Director's overall objectives at the time the candidate is being evaluated.

**(b)** For the years ended December 31, 2025 and 2024, the adjustments related primarily to acquisition-related costs related to our Horizon acquisition. For the year ended December 31, 2023, the adjustment related primarily to noncash amortization of intangible assets from business acquisitions.

**(c)** For the years ended December 31, 2025, 2024, and 2023, the adjustments related primarily to acquisition-related costs related to our Horizon acquisition.

**(d)** For the year ended December 31, 2025, the adjustment related to intangible asset impairment charges for Otezla<sup>®</sup>. For the year ended December 31, 2024, the adjustment related primarily to impairment charges for IPR&D intangible assets related to our Teneobio, Inc. acquisition from 2021. For the year ended December 31, 2023, the adjustment related primarily to an IPR&D intangible asset impairment charge for AMG 340.

**(e)** The adjustments related to separation costs associated with our restructuring plan and other cost-savings initiatives.

**(f)** For the year ended December 31, 2023, the adjustments included (i) interest expense and income on senior notes issued in March 2023 and (ii) debt issuance costs and other fees related to our bridge credit and term loan credit agreements, incurred prior to the closing of our acquisition of Horizon.

**(g)** For the year ended December 31, 2025 and 2023, the adjustments related primarily to our BeOne Medicines Ltd. equity fair value adjustment.

**(h)** The tax effect of the adjustments between our GAAP and non-GAAP results takes into account the tax treatment and related tax rate(s) that apply to each adjustment in the applicable tax jurisdiction(s). Generally, the tax impact of adjustments, including the amortization of intangible assets and acquired inventory, gains and losses on our investments in equity securities and expenses related to restructuring and cost-savings initiatives, depends on whether the amounts are deductible in the respective tax jurisdictions and the applicable tax rate(s) in those jurisdictions. Due to these factors, the effective tax rate for the adjustments to our GAAP income before income taxes for the year ended December 31, 2025 was 18.0% compared with 19.4% and 20.3% for 2024 and 2023, respectively.

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