Re: Position on the Board of Directors of SiTime Corporation

Dear Faraj:

We are pleased to invite you to join the SiTime Corporation (the “Company”) Board of Directors (the “Board”), contingent upon Board approval and effective on January 21, 2026. We anticipate many exciting opportunities at the Company and believe that your experience and background will greatly assist us in meeting those opportunities.

The Company maintains a classified Board, which means the Board is divided into three classes, with each class having a three-year term. You shall serve as a Class II director. As a result, your term of office will expire at the Company’s 2027 Annual Meeting of Stockholders. At such time you will be nominated for election to an additional three-year term. If you are not re-elected, your term of office will expire at the 2027 Annual Meeting of Stockholders.

A copy of our current Independent Director Compensation Policy is attached as Exhibit A (the “Policy”). In connection with your appointment to the Board, pursuant to the terms of the Policy and the Company’s 2019 Stock Incentive Plan (the “Plan”), you will be granted a restricted stock unit (“RSU”) award of 837 shares of the Company’s common stock (the “Initial RSU”). Your Initial RSU will vest annually over a three-year period with one-third of the shares subject to the Initial RSU vesting on February 20, 2026, and an additional one-third of the shares vesting on each February 20th thereafter, subject to your continued service as a Director at each vesting date. Additionally, you will be granted an RSU award of 246 shares (the “Prorated Annual RSU Award”). The Prorated Annual RSU Award shall become fully vested on May 20, 2026, subject to your continued services as a Director at the vesting date. In the event of a Change in Control of the Company, 100% of your Initial RSU and Prorated Annual RSU Award shall become vested. All terms and conditions of the Initial RSU and Prorated Annual RSU Award will be set forth in the Policy, the Plan, the RSU award agreement and other documents relating to the Plan.

You will be granted such additional equity awards in the future as shall be determined by the Company’s Nominating and Corporate Governance Committee and will be eligible to receive such cash retainers paid to directors and committee members, in accordance with the Company’s then-effective independent director compensation policy. All compensation is contingent upon your appointment by the Board.

In addition, the Company will reimburse reasonable out-of-pocket expenses incurred in connection with your service as a Director in accordance with the Company’s established reimbursement policies, including reasonable travel expenses associated with attending the Company’s Board meetings, as well as meetings of any committees that you join. As you know, as a Director, you will not be entitled to any of the other benefits that the Company makes available to its employees.

In your capacity as a Director of the Company, you will be expected not to use or disclose any confidential information, including, but not limited to, trade secrets of any former employer or other person or entity to whom you have an obligation of confidentiality. Rather, you will be expected to use only information that is generally known and used by persons with training and experience comparable to

your own, that is common knowledge in the industry or otherwise legally in the public domain, or that is otherwise provided or developed by the Company.

In addition, during the term of your services as a Director and after termination of such services, you will not disclose any of the Company’s confidential proprietary information, or any information of a third party provided to you by the Company, which includes but is not limited to, all non-public tangible and intangible manifestations regarding patents, copyrights, trademarks, trade secrets, technology, inventions, works of authorship, business plans, data or any other confidential knowledge without the prior written consent of the Company.

You will be entitled to indemnification for your services as a Board member in accordance with the Company’s Amended and Restated Bylaws and Amended and Restated Certificate of Incorporation, as may be amended and/or amended and restated from time to time. In addition, the Company will enter into an Indemnity Agreement with you in substantially the same form as is in place with the other members of the Board.

This letter, along with the stock equity documentation referred to herein, constitutes the entire agreement between you and the Company. This agreement supersedes any other agreements or promises made to you by anyone, whether oral or written, and it may only be modified in writing signed by a duly authorized officer of the Company.

If the terms of this letter are acceptable to you, and to indicate your willingness to serve on the Company’s Board, please sign and date this letter below. We look forward to your favorable reply and to a productive and enjoyable future relationship.

Very truly yours,

SiTime Corporation
