EXPLANATORY NOTE

Cohu, Inc. (the “Company”) previously filed (i) Registration Statement on Form S-8 (File No. 333-132605) with the Securities and Exchange Commission (the “Commission”) on March 21, 2006, (ii) Registration Statement on Form S-8 (File No. 333-160760) with the Commission on July 23, 2009, (iii) Registration Statement on Form S-8 (File No. 333-186973) with the Commission on February 28, 2013, (iv) Registration Statement on Form S-8 (File No. 333-207016) with the Commission on September 18, 2015, (v) Registration Statement on Form S-8 (File No. 333-233080) with the Commission on August 7, 2019; and (vi) Registration Statement on Form S-8 (File No. 333-273711) with the Commission on August 4, 2023 (collectively, the “Prior Registration Statements”), to register the offer and sale of shares of the Company’s common stock, par value $1.00 per share (the “Common Stock”) issuable under the Company’s 2005 Equity Incentive Plan (the “Prior Plan”).

On May 15, 2026 (the “Effective Date”), the Company’s stockholders approved the Company’s 2026 Equity Incentive Plan (the “2026 Plan”) as a successor to the Prior Plan. Effective as of the Effective Date, no additional awards may be granted under the Prior Plan, and all awards granted under the Prior Plan that are outstanding on the Effective Date will remain subject to the terms of the Prior Plan (except to the extent such outstanding awards result in Returning Shares (as defined below) that become available for issuance pursuant to awards granted under the 2026 Plan). Under the terms of the 2026 Plan, a maximum of 3,400,000 shares of Common Stock, less one share for each share subject to any equity award granted under the Prior Plan between March 20, 2026 and prior to the Effective Date (the “Newly Authorized Shares”); plus any shares of Common Stock subject to share awards granted under the Prior Plan that are outstanding on March 16, 2026 or which are granted and outstanding after March 16, 2026 and prior to the Effective Date, and that: (i) are subject to stock options or stock appreciation rights which expire, or for any reason are forfeited, cancelled, or terminated without being exercised; (ii) are not issued because such share award or any portion thereof expires or otherwise terminates without all of the shares covered by such share award having been issued; (iii) are not issued because such award or any portion thereof is settled in cash; or (iv) are forfeited back to or repurchased by the Company for an amount not greater than the participant's purchase price because of the failure to meet a contingency or condition required for the vesting of such shares (the “Returning Shares”) may be issued under the 2026 Plan. Shares subject to outstanding awards granted under the Prior Plan that are (A) withheld by the Company in satisfaction of the payment of the purchase or exercise price of an option or stock appreciation right, or (B) withheld by the Company in satisfaction of the payment of withholding taxes, are not Returning Shares and will not become available for issuance under the 2026 Plan.

The purpose of this Post-Effective Amendment No. 1 (the “Post-Effective Amendment”) to the Prior Registration Statements is to register the Returning Shares for issuance under the 2026 Plan (as such shares would no longer be issuable under the Prior Plan), in accordance with Item 512(a)(1)(iii) of Regulation S-K and Securities Act Forms Compliance and Disclosure Interpretation 126.43. No additional securities are being registered by this Post-Effective Amendment.

Contemporaneously with the filing of this Post-Effective Amendment, the Company is filing a Registration Statement on Form S-8 to register the Newly Authorized Shares for offer and sale under the 2026 Plan.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Delaware law authorizes corporations to eliminate the personal liability of directors and, subject to statutory limitations, certain officers to corporations and their stockholders for monetary damages for breach or alleged breach of the directors’ or officers’ “duty of care” to the extent permitted by Section 102(b)(7) of the Delaware General Corporation Law (the “DGCL”). While the relevant statute does not change directors' or officers’ duty of care, it enables corporations to limit available relief to equitable remedies such as injunction or rescission. The statute has no effect on directors' or officers’ duty of loyalty, acts or omissions not in good faith or involving intentional misconduct or knowing violations of law, illegal payment of dividends and approval of any transaction from which a director or officer derives an improper personal benefit.

The Company has adopted provisions in its Amended and Restated Certificate of Incorporation, as amended, which eliminate the personal liability of its directors and, to the extent permitted by the DGCL, its officers to the Company and its stockholders for monetary damages for breach or alleged breach of their duty of care. The bylaws of the Company provide for indemnification of its directors, officers, employees and agents to the fullest extent permitted by the General Corporation Law of the State of Delaware, the Company's state of incorporation, including those circumstances in which indemnification would otherwise be discretionary under Delaware Law. Section 145 of the General Corporation Law of the State of Delaware permits a corporation to indemnify any director or officer of the corporation against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred in connection with any action, suit, or proceeding brought by reason of the fact that such person is or was a director or officer of the corporation, if such person acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, if he or she had no reason to believe his or her conduct was unlawful. In a derivative action, or an action brought by or on behalf of the corporation, indemnification may be provided only for expenses actually and reasonably incurred by any director or officer in connection with the defense or settlement of such an action or suit if such person acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification shall be provided if such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which the action or suit was brought shall determine that the defendant is fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability.

The Company has entered into indemnification agreements with certain of its executive officers and directors, indemnifying them against certain potential liabilities that may arise as a result of their service to the Company, and providing certain other protections. The Company also maintains insurance policies which insure the officers and directors against certain liabilities.

Item 9. Undertakings.

A. The undersigned Registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in Exhibit 107 to the effective Registration Statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that clauses (A)(1)(i) and (A)(1)(ii) above shall not apply if the information required to be included in a post-effective amendment by those clauses is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement;

(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

(3) to remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference into this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereby, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Post-Effective Amendment No. 1 to Form S-8 Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Diego, State of California, on May 15, 2026.
