Retirement of Peter H. Griffith, Chief Financial Officer

On May 19, 2026, Amgen Inc. (the “Company”) publicly announced that Peter H. Griffith will retire from the role of the Company’s Executive Vice President and Chief Financial Officer, effective August 31, 2026. In connection with the transition of his role, Mr. Griffith will remain employed as an Executive Vice President, a non-executive officer position from September 1, 2026 until January 31, 2027. Mr. Griffith is currently retirement eligible under the Company’s plans and policies, and thus upon his departure in January 2027 will receive the retirement benefits provided by the Company’s plans and policies, described in the Company’s filings, including the Company’s proxy statement.

Appointment of Thomas Dittrich, Executive Vice President and Chief Financial Officer

In connection with Mr. Griffith’s retirement, on May 19, 2026, the Board of Directors approved hiring Thomas Dittrich, age 62, to serve as Executive Vice President, a non-executive officer position, effective July 1, 2026 through August 31, 2026.

Effective September 1, 2026, he will serve as Executive Vice President and Chief Financial Officer of the Company. Mr. Dittrich will report to Robert A. Bradway, Chairman and Chief Executive Officer.

Mr. Dittrich will initially be based in Rotkreuz, Switzerland and will be employed by Amgen (Europe) GmbH pursuant to an Employment Offer Agreement with Amgen (Europe) GmbH dated May 16, 2026. Mr. Dittrich is expected to relocate to Thousand Oaks, California in connection with his transition to Chief Financial Officer in September 2026.

The Employment Offer Agreement provides that Mr. Dittrich will receive an annual base salary of CHF 1,070,000 and will be eligible to participate in the Company’s Global Management Incentive Plan with a target opportunity of 100% of base salary. As long-term equity compensation for fiscal 2026, Mr. Dittrich will be granted annual long-term incentive awards with a target value of CHF 4,500,000, composed of non-qualified stock options valued at CHF 1,350,000 and restricted stock units (“RSUs”) valued at CHF 900,000, that each vest 25% per year from the date of grant, and 2026-2028 long-term performance units (with modified goals to account for mid-year hire date) valued at CHF 2,250,000.

In order to compensate Mr. Dittrich for foregone equity and incentive compensation at his current employer, he will be granted a one-time RSU award with a value of CHF 4,700,000 that vests 25% per year from the date of grant, and a one-time cash bonus of CHF 4,000,000 as part of his Swiss employment.

Separately, to also compensate Mr. Dittrich for foregone equity and incentive compensation at his current employer, Mr. Dittrich will receive a one-time, two-year retention bonus of CHF 5,800,000, that is repayable, pro-rata based on days served, in the event Mr. Dittrich resigns, or the Company terminates his employment for certain misconduct, within two years of his hire date.

In connection with his relocation to Thousand Oaks from Switzerland in September 2026 in order to assume the CFO role, Mr. Dittrich's employment will be transferred to Amgen International AG and he will receive relocation benefits generally provided to other Executive Vice Presidents who relocate, plus a relocation allowance of CHF 250,000. These relocation benefits are provided under an Expatriate Assignment Letter of Understanding dated May 16, 2026.

Mr. Dittrich will also receive our standard severance agreement that provides severance protection in the event of a termination of employment by the Company, other than for cause, within two years of his hire date at a benefit multiple of two times his salary and target bonus.

The foregoing descriptions of the Employment Offer Agreement and the Expatriate Assignment Letter of Understanding do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements, which are filed as Exhibits 10.1 and 10.2, respectively, to this Current Report on Form 8-K and incorporated herein by reference.

The actual results depend on corporate goal performance and individual goal performance as assessed by Employee`s manager.

Page 5 of 19

Long term Incentive (LTI)

Subject to the approval of the Compensation and Management Development Committee of the Board of Directors or the Equity Award Committee of Amgen Inc. (the Committee), and subject to the vesting rules, Employee will be granted a one-time award of restricted stock units (RSUs) with a CHF value of 4,700,000 no later than the next regular grant date on or following the Start Date. The actual number of RSUs to be awarded shall be determined by dividing the grant value by the Amgen common stock closing price on the applicable grant date. Upon each applicable vesting date, Employee will receive a number of shares of Amgen common stock equal to the number of restricted stock units that vest, less any shares that are withheld to satisfy applicable taxes. This grant will vest beginning with the first anniversary of the grant date through the fourth anniversary at a rate of 25% each year, respectively, contingent upon Employee being actively employed with Amgen through each vesting date. Should you become retirement eligible (as defined by Amgen) and elect to retire prior to the full-vesting period of this grant, this grant will not be eligible for retirement treatment and you will forfeit the unvested portions of this grant. RSUs will be subject to the terms and conditions set forth in the applicable grant agreement.

Employee will be eligible to receive RSUs, performance units (PUs) and stock options as part of Amgen Inc.’s LTI program subject to the terms and conditions of such program as communicated by Amgen from time to time.

For 2026, the Employee will receive an annual LTI grant with a target value of CHF 4,500,000, which will be provided as follows:

CHF 1,350,000 in non-qualified stock options following a four-year pro-rata vesting schedule; and

•

CHF 900,000 in RSUs, following a four-year pro-rata vesting schedule.

Page 6 of 19

For years after 2026, the target value of Employee’s annual LTI grants will be CHF 4,500,000. Employee acknowledges that grants under the LTI program are discretionary under the employee annual performance review process and as approved by the Committee, and thus do not form a part of Employee`s guaranteed remuneration package.

As a Group Company executive you will be required to hold Amgen common stock in accordance with the Amgen Stock Ownership Guidelines. Your holding requirement is based on your Amgen GCF level and as an Executive Vice President you will be required to hold Amgen common stock in the amount equal to 3X your base salary. You must meet your holding requirement by December 31st of the fifth calendar year following the date on which you became an Officer of a Group Company. To help you meet your holding requirement, the Amgen Stock Ownership Guidelines prohibit you from selling stock that you receive as part of your LTI awards (including shares that you receive as a result of option exercise, special, promotional, and annual grants) until you have met your required stock ownership level.

4.5.

The Employee hereby acknowledges that said retirement benefits may be modified from time to time.

4.7.

Acknowledgement of the Employee

The Employee acknowledges and agrees that any entitlements granted and payments made in addition to the Base Salary, including, but not limited to any bonuses, participations, or gratuities of the Company or another Group Company (the Additional Payments) are not contractually owed by the Company and are made at the full discretion of the Company unless expressly agreed in this Employment Offer. Any Additional Payments shall not create any obligation of the Company to make such Additional Payments in future and shall not create any right or entitlement of the Employee to such Additional Payments in future even if paid over consecutive years and without express reservation.

4.8.

No other Compensation

The Employee acknowledges and agrees that he/she shall not be entitled to receive any other compensation or benefit of any nature from the Company except as expressly provided for in this Employment Offer.

The following are such benefits: two (2) years of the Employee’s Base Salary then in effect, and two (2) times the Employee’s Incentive Plan target opportunity (i.e., GMIP or successor bonus plan target, which is currently 100%), then in effect, paid in a lump sum by the second payroll date following the date which the release of claims becomes non-revocable. Payments made during the notice period shall be a part of these benefits, respectively deducted from the benefits.

In the event of a Change of Control (as defined in the Amgen Inc. Change of Control Severane Plan or any successor plan (the Change of Control Plan)), Employee will be eligible for severance benefits as if Employee were a Participant in the Change of Control Plan, consistent with his GCF level.

I understand that it is my obligation to declare all income and pay all taxes owed on such income, if any.

This Agreement shall be construed in accordance with and governed by Swiss law (without giving effect to the principles of conflicts of law).

Dear Thomas

This letter serves to outline the terms and conditions of your temporary assignment to Thousand Oaks, California, USA. It is contingent upon the approval of immigration clearance and any applicable regulatory license/requirements being met. You will be assigned to the Host Country as an Executive Vice President, GCF Level 11 reporting to Robert Bradway.

Although your Assignment is to work for Amgen Inc., you will be employed by Amgen International AG throughout the duration of your assignment. Your assignment is pursuant to the Intercompany Secondment Agreement between Amgen International AG and Amgen Inc. While you continue to be employed by Amgen International AG, you will provide services exclusive to Amgen Inc. and you will be subject to the direction and control of Amgen Inc. Any services you rendered to Amgen Inc. during your Assignment are not for or on behalf of Amgen International AG.

Further, we would like to confirm and the parties signing this Letter of Understanding herewith acknowledge and agree that for the purpose of the Assignment, your employment offer with Amgen (Europe) GmbH (the “Employment Offer”) will be transferred in whole, including all rights and obligations, to Amgen International AG, Suurstoffi 22,6343 Risch/Rotkreuz, Switzerland. During the term of your Assignment, however, this Letter of Understanding sets out all the terms and conditions, including all rights and obligations, applying to the Assignment.

Your Employment Offer remains a permanent contract and can be terminated by you or by Amgen International AG according to the terms as agreed upon in the Employment Offer. Any termination of the Assignment during the Assignment period shall be handled according to the termination provisions set out below. Any reference to home country policy shall mean the policies of Amgen (Europe) GmbH as amended from time to time.

Nothing in this Letter of Understanding constitutes a promise or guarantee of any compensation or benefit or anything else. Amgen Inc. and/or its subsidiaries or related or affiliated companies (collectively, “AMGEN” or the “Company”) reserve the right to modify or terminate the Assignment and/or the terms and conditions set forth in this Letter of Understanding, at any time, in its sole discretion, with or without cause and with or without advance notice, and to repatriate you and your qualified dependents in the host location to your home country. Accordingly, AMGEN may change, modify, amend or eliminate any or all of the benefits set forth in this Letter of Understanding.

Commencement / Duration of Assignment

The anticipated commencement date of your assignment will be September 1, 2026. The initial phase of your assignment is expected to last for a period of up to 48 months.

Amgen Forward-Looking Statements

This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeOne Medicines Ltd.), the performance of Otezla® (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 news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.

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.
