Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers. Aehr Test System (the “ Company” or “us”) entered into new Change in Control and Severance Agreements (each, a “ Severance Agreement”) on August 31, 2024 with Gayn Erickson, the Company’s President and Chief Executive Officer, Chris P. Siu, the Company’s Executive Vice President of Finance and Chief Financial Officer, and each other executive officer of the Company, pursuant to which the executives will be entitled to severance benefits in the event of certain qualifying terminations of employment, or a termination of employment due to death or disability, as described below. Each Severance Agreement supersedes and replaces each executive’s prior change in control and severance agreement with the Company. A “qualifying termination of employment” for purposes of the Severance Agreements means an involuntary termination of the executive’s employment by the Company without “cause”, or the executive’s resignation from employment with the Company for “good reason” (each as defined in the applicable Severance Agreement). As described below, each Severance Agreement provides for enhanced severance benefits if an executive undergoes a qualifying termination of employment during a “change in control period,” which means the period beginning three months before and ending 24 months (for Mr. Erickson), 18 months (for Mr. Siu) or 12 months (for other executive officers) after a change in control of the Company. Payments and benefits under each Severance Agreement are contingent on the applicable executive timely providing us with (and not revoking) a general release of claims. If an executive officer undergoes a qualifying termination of employment during a change in control period, the executive will be eligible for the following: a cash payment equal to 24 months (for Mr. Erickson), 18 months (for Mr. Siu) or 12 months (for other executive officers) of the executive’s annual base salary; ──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── a cash payment equal to 200% (for Mr. Erickson), 150% (for Mr. Siu) or 100% (for other executive officers) of the executive’s target annual cash incentive opportunity for the year in which the employment termination occurs; a cash payment equal to the prorated amount of the executive’s target annual cash incentive opportunity for the fiscal year in which the employment termination occurs, determined by the portion of the fiscal year during which the executive was employed by the Company; acceleration of vesting of all of the executive’s then unvested outstanding equity awards that vest solely based on continued service over time, and with respect to equity awards that vest based on the attainment of performance-based conditions that remain unsatisfied as of immediately before the employment termination, such performance-based conditions shall be deemed achieved at the greater of target or the expected attainment level based on performance as of the employment termination ... up to 24 months (for Mr. Erickson), 18 months (for Mr. Siu) or 12 months (for other executive officers) of continued healthcare coverage paid by the Company. If an executive officer undergoes a qualifying termination of employment outside of a change in control period, the executive will be eligible to receive the following: a cash payment equal to 12 months (for Mr. Erickson), nine months (for Mr. Siu) or six months (for other executive officers) of the executive’s annual base salary; ──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── a cash payment equal to the prorated amount of the executive’s target annual cash incentive opportunity for the fiscal year in which the employment termination occurs, determined by the portion of the fiscal year during which the executive was employed by the Company; 12 months’ (for Mr. Erickson), nine months’ (for Mr. Siu) or six months’ (for other executive officers) accelerated vesting of unvested outstanding equity awards (with any performance-based conditions deemed achieved at target levels); and up to 12 months (for Mr. Erickson), nine months (for Mr. Siu) or six months (for other executive officers) of continued healthcare coverage paid by the Company. If the employment of an executive officer terminates due to the executive’s death, the executive (and his estate) will be eligible to receive the same severance benefits the executive would be eligible for in connection with a qualifying termination of employment outside of a change in control period (described above), except for continued healthcare coverage paid by the Company. If the employment of an executive officer terminates due to the executive’s disability (as defined in the applicable Severance Agreement), the executive will be eligible for the same severance benefits the executive would be eligible for in connection with a qualifying termination of employment outside of a change in control period (described above), except that during the 12-month (for Mr. Erickson), nine-month (for Mr. Siu) or six-month (for other executive officers) period following the employment termination, the executive will continue to participate at the Company’s cost in the Company’s ArmadaCare supplemental benefits plan (or any similar replacement or successor supplemental benefits plan). The foregoing description of the Severance Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the Severance Agreements, and a copy of the form of Severance Agreement is filed herewith as Exhibit 10.1 and incorporated by reference herein.
