Re: Transition Services Agreement

Dear Mike:

Thank you for your work on behalf of Astera Labs. This transition services agreement (this “Agreement”) confirms the agreement between you and Astera Labs, Inc. (the “Company”) regarding your voluntary resignation from the Company and your transition out of the Company.

1. Transition and Resignation; Advisory Services. Your anticipated last day in your role as Chief Financial Officer of the Company is March 1, 2026 (the “Transition Date”). You and the Company anticipate that, provided you comply with the terms and conditions of this Agreement and comply with all Company policies, from the date of this Agreement through the Last Day (as defined below), you will remain a full-time Company employee and the Company will continue to pay you your current base salary through the Transition Date and adjusted salary during the Transition Period (as described below), you will continue to vest in any of your outstanding equity awards of the Company, and the Company will continue to provide you with your Company-sponsored benefits.

Beginning on March 2, 2026 and continuing through September 1, 2026 (the “Transition Period”), you will transition to a new role as an employee strategic advisor (“Advisor”) to the Chief Executive Officer (CEO) of the Company. You agree to perform your role as Advisor to the best of your abilities and may be asked to attend certain meetings, such as investor meetings, audit committee meetings, or leadership team meetings. For the duration of the Transition Period, your salary will be $131,250.00, which is 25% of your current base salary, to be paid on a bi-monthly basis in accordance with the Company’s regular payroll practices, and subject to applicable taxes, withholdings, and any other authorized or legally required deductions. During the Transition Period, you will continue to vest in any of your outstanding equity awards of the Company, and the Company will continue to provide you with your Company-sponsored benefits. During the Transition Period, you will remain covered by the terms of that certain indemnification agreement between you and the Company, dated November 14, 2022 (“Indemnification Agreement”). Your full-time employment with the Company will end on September 1, 2026 (the “Last Day”).

Notwithstanding the foregoing, you understand that your employment remains at-will up to your Last Day. If you obtain new full time employment prior to your anticipated Last Day, or obtain part-time or full time employment with a competitor of the Company, you must notify the General Counsel in writing as soon as possible and no later than at least five days in advance of the start of the new employment, and upon notice you will be deemed to have resigned your employment with the Company earlier than the anticipated Last Day, in which case such earlier date will become the “Last Day” for the purposes of this Agreement.

2. Separation Benefit. Although you are not otherwise entitled to receive any severance payments or severance benefits from the Company in conjunction with your transition and resignation from the Company, subject to, and in consideration for, your timely execution and non-revocation of this Agreement, and provided you comply with all the terms and conditions of this Agreement, your Confidentiality Agreement (as defined below), and all Company policies, the Company will provide you with the following separation benefits: a lump sum severance payment of $1,000.00, less all applicable federal, state and local withholding taxes and any other authorized or legally-required deductions, which will be paid to you no later than 30 days after your Last Day, provided you also execute of Exhibit A to this Agreement within five days after your Last Day, and provided you comply with all the terms and conditions of this Agreement and Exhibit A, your Confidentiality Agreement, and all Company policies.

3. Restricted Stock Units.

The details of any such Awards are reflected in your personal E*Trade account.

You acknowledge and agree that, other than the Awards described in this Section, you do not have any right, title, claim or interest in or to any of the Company’s securities, including, without limitation, any shares of the Company’s capital stock or any options or other rights to purchase or receive shares of the Company’s capital stock.

4. Your General Release.

a. In consideration for receiving the Separation Benefit set forth in Section 2, you hereby waive and release to the maximum extent permitted by applicable law any and all claims or causes of action, whether known or unknown, against the Company and/or its respective predecessors, successors, past, present or future parent companies or subsidiaries, affiliated companies, investors or related entities (collectively, including the Company, the “Entities”) and/or the Entities’ respective past, present or future insurers, officers, directors, agents, attorneys, employees, shareholders, assigns and employee benefit plans (collectively with the Entities, the “Released Parties”), with respect to any matter, including, without limitation, any matter related to or arising out of your employment with the Company, through the date you sign this Agreement.

b. This waiver and release includes, without limitation, claims under the Employee Retirement Income Security Act; claims for attorneys’ fees or costs; any and all claims for stock, stock options, RSUs or other equity securities of the Company; penalties claims; claims related to disputed or paid wages; statutory claims; tort claims; contract claims; claims of wrongful discharge, constructive discharge, emotional distress, defamation, invasion of privacy, fraud, breach of contract, and breach of the covenant of good faith and fair dealing; claims for retaliation; claims related to discrimination or harassment based on any protected basis, under Title VII of the Civil Rights Act, the Age Discrimination in Employment Act, the California Fair Employment and Housing Act, the Americans with Disabilities Act, or any other federal, state, or local law prohibiting discrimination, harassment or retaliation; and claims under the California Labor Code, the California Business and Professions Code, and all other federal, state and local laws, ordinances and regulations.

In addition, you expressly waive and release any and all rights and benefits under Section 1542 of the Civil Code of the State of California (or any similar law of any state or territory), which reads as follows: “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.”

6. ADEA Waiver. You acknowledge that you are knowingly and voluntarily waiving and releasing any rights you may have under the Federal Age Discrimination in Employment Act (“ADEA Waiver”) and that the consideration given for the ADEA Waiver is in addition to anything of value to which you are already entitled.

You agree that any modifications, material or otherwise, made to this Agreement do not restart or affect in any manner the original 21-day consideration period provided in this paragraph. You acknowledge that your consent to this Agreement is knowing and voluntary. The severance offer will be automatically withdrawn if you do not sign the Agreement within the 21-day consideration period.

7. No Admission. Nothing contained in this Agreement shall constitute or be treated as an admission by the Company of any liability, wrongdoing, or violation of law. Neither this Agreement nor any of its terms may be used as an admission or introduced as evidence as to any issue of law or fact in any proceeding, suit or action, other than an action to enforce this Agreement.

8. Continuing Obligations. At all times in the future, including after your Last Day, you will remain bound by the Confidential Information and Inventions Agreement previously entered into by and between you and the Company (the “Confidentiality Agreement”).

9. Return of Company Property. You agree that by the Last Day (or sooner if requested by the Company) you will return to the Company your Company laptop, security badge, and corporate credit card; and return or destroy all confidential (including all nonpublic information about the Company, its products, financials, customers or business transactions), proprietary or trade secret information belonging to the Company or related to any Company customer, partner or employee. In addition, you agree that, as of the Last Day, you will personally delete, erase, and/or permanently remove any and all Company information from all personal computers, tablets, mobile phones and other electronic devices, physical and virtual databases, and all other locations (subject, in each case, to any applicable litigation hold notice) and permanently disable access to any Company repositories, databases or directories.

10. Non-Disparagement. To the fullest extent permitted by law and except as otherwise provided in this Agreement, including without limiting the Protected Activities (as defined below), you agree that you will not disparage or encourage or induce others to disparage the Company or any of the other Released Parties. For the purpose of this Section 10, “disparage” includes, without limitation, making comments or statements online or to any person or entity including, but not limited to, the press and/or media, former employees, employees, partners, or principals of the Company or any entity with whom the Company has a business relationship, that knowingly or is reasonably likely to adversely affect in any manner (a) the conduct of the business of the Company or any of the other Released Parties (including, but not limited to, any business plans or prospects) or (b) the reputation of the Company or any of the other Released Parties.

11. Protected Activities. Notwithstanding anything to the contrary herein, nothing in this Agreement, the Confidentiality Agreement, or any other agreement you have with the Company or its affiliates will prohibit you or restrict you from (a) voluntarily communicating with an attorney retained by you, (b) providing truthful information as required or permitted by law, including in a legal proceeding or government investigation, (c) voluntarily communicating with any law enforcement, government agency, including the SEC, the EEOC, or a state or local commission on human rights, or any self-regulatory organization regarding possible violations of law, in each case without advance notice to the Company, (d) discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that you have reason to believe is unlawful or in violation of a clear mandate of public policy, (e) exercising rights under Section 7 of the National Labor Relations Act or state law to discuss wages, benefits, working conditions, or other terms and conditions of employment, (f) recovering a SEC whistleblower award as provided under Section 21F of the Securities Exchange Act of 1934, (g) disclosing any confidential information to a court or other administrative or legislative body in response to a subpoena, court order or written request, provided that you first promptly notify and provide the Company with the opportunity to seek, and join in its efforts at the sole expense of the Company, to challenge the subpoena or obtain a protective order limiting its disclosure, or other appropriate remedy, or (h) filing or disclosing any facts necessary to receive unemployment insurance, Medicaid or other public benefits to which you are entitled. Further, pursuant to 18 U.S.C. § 1833(b), you understand that you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret of the Company or its affiliates that (i) is made (x) in confidence to a federal, state, or local government official, either directly or indirectly, or your attorney and (y) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. You understand that if you file a lawsuit for retaliation by the Company or its affiliates for reporting a suspected violation of law, you may disclose the trade secret to your attorney and use the trade secret information in the court proceeding if you (A) file any document containing the trade secret under seal, and (B) do not disclose the trade secret, except pursuant to court order. Nothing in this Agreement, or any other agreement that you have with the Company or any of its affiliates, is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section. The activities and disclosures described in this Section shall be collectively referred to herein as the “Protected Activities” and shall apply to this Agreement and release in Exhibit A.

12. Cooperation. Subject to the Protected Activities as provided in Section 11 of this Agreement, you agree to fully cooperate with the Company and its counsel as it relates, in a reasonable manner, to any issue or matter that may arise as the subject of litigation or administrative inquiry, which occurred during your employment with the Company, but excluding any claims or demands brought by or on behalf of you against the Company. Full cooperation shall include, but is not limited to, review of documents, attendance at meetings, trial or administrative proceedings, depositions, interviews, or production of documents to the Company without the need of the subpoena process. You shall be reimbursed for all out-of-pocket expenses incurred by you as a result of such cooperation.

13. Entire Agreement. You and the Company agree that this Agreement and the Confidentiality Agreement constitutes the entire agreement between you and the Company regarding the subject matter of this Agreement. Other than the Confidentiality Agreement, and any relevant provisions of the CoC Severance Policy, Indemnification Agreement and any applicable grant agreements, all prior or contemporaneous negotiations, agreements, understandings, or representations regarding the subject matter of this Agreement are expressly superseded hereby and are of no further force and effect. This Agreement may only be modified in a written document signed by you and an authorized representative of the Company.

14. Governing Law. This Agreement shall be construed and interpreted in accordance with the laws of the state of California.

15. Severability. The provisions of this Agreement are severable. If any provision of this Agreement is held invalid or unenforceable, such provision shall be deemed deleted from this Agreement and such invalidity or unenforceability shall not affect any other provision of this Agreement, the balance of which will remain in and have its intended full force and effect; provided, however that if such invalid or unenforceable provision may be modified so as to be valid and enforceable as a matter of law, such provision shall be deemed to have been modified so as to be valid and enforceable to the maximum extent permitted by law.

16. Interpretation. This Agreement, and the provisions contained in it, shall not be construed or interpreted for, or against, any party to this Agreement because that party drafted or caused that party’s legal representatives to draft any of its provisions. You agree that the terms of this Agreement, including the economic terms, have been individually negotiated.

17. Counterparts. This Agreement may be executed in counterparts, each of which shall be an original, but all of which together shall constitute one agreement. Execution via DocuSign or a similar service, or of a facsimile copy or scanned image shall have the same force and effect as execution of an original, and an electronic or facsimile signature or scanned image of a signature shall be deemed an original and valid signature.
