COHU INC

Certificate of Correction to Amended Restated Certificate of Incorporation

On January 6, 2025, Plaintiff Keith Palmer (“Plaintiff”), a stockholder of Cohu, Inc. (“Cohu” or the “Company”), filed a stockholder class action complaint against the Company challenging certain provisions of Cohu’s Certificate of Incorporation (the “Charter”) as being in violation of the Delaware General Corporate Law. In response, on April 3, 2025, the Company filed a Certificate of Correction with the State of Delaware correcting Article Fourteen of the Charter to redress any concerns by Plaintiff. On April 2, 2025, the Court entered an Order granting a stipulation dismissing the action as moot and retaining jurisdiction to determine Plaintiff’s counsel’s application for an award of attorneys’ fees and reimbursement of expenses (the “Fee and Expense Application”).

The Company has subsequently agreed to pay $125,000 in attorneys’ fees and expenses to plaintiff’s counsel in full satisfaction of the Fee and Expense Application in the Palmer Action. On June 20, 2025, the Court entered an order closing the case, subject to Cohu filing an affidavit with the Court confirming that this notice has been issued. In entering the order, the Court was not asked to review, and did not pass judgment on, the Fee and Expense Application or the reasonableness of the payment of the attorneys’ fees and expenses. Additional information can be found in the copy of the Stipulation, which is filed as exhibit 10.1 to this 10-Q, and is incorporated by reference herein.

Rule 10b5-1 Trading Plans

Our directors and executive officers may purchase or sell shares of our common stock in the market from time to time, including pursuant to equity trading plans adopted in accordance with Rule 10b5-1 under the Exchange Act and in compliance with guidelines specified by our insider trading policy. In accordance with Rule 10b5-1 and our insider trading policy, directors, officers and certain employees who, at such time, are not in possession of material non-public information are permitted to enter into written plans that pre-establish amounts, prices and dates (or formula for determining the amounts, prices and dates) of future purchases or sales of our stock, including shares acquired pursuant to our equity incentive plans. Under a Rule 10b5-1 trading plan, a broker executes trades pursuant to parameters established by the director or executive officer when entering into the plan, without further direction from them. The use of these trading plans permits asset diversification as well as personal financial and tax planning. Our directors and executive officers may also buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material nonpublic information, subject to compliance with SEC rules, the terms of our insider trading policy and certain minimum holding requirements. The following table shows the Rule 10b5-1 trading plans intended to satisfy the affirmative defense conditions of Rule 10b-1(c) adopted or terminated by our directors and executive officers during the second quarter of 2025.

During the second quarter of 2025, none of our directors or executive officers terminated a Rule 10b5-1 trading plan or adopted or terminated a non-Rule 10b5-1 trading arrangement (each term as defined in Item 408 of Regulation S-K).
