## Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangement of Certain Officers.
Amtech Systems, Inc. (the "Company") announced that Wade M. Jenke has submitted his resignation as Chief Financial Officer and an employee of the Company, effective as of the close of business on December 29, 2025, to assume an executive role at another company. Mr. Jenke's decision to step down is not the result of any dispute or disagreement with the Company on any matter relating to its accounting or financial policies or procedures or its financial statements or disclosure. Mr. Jenke has agreed to serve in a consulting capacity to the Company after his resignation for a period of up to six months, to assist the Company with the closing of its first quarter of fiscal 2026, the preparation and filing of its 2026 annual meeting proxy statement, and the transition of his duties to a new Chief Financial Officer. In consideration for providing such consulting services, the Company has agreed to pay Mr. Jenke an hourly rate equivalent to his current hourly rate for such services and to accelerate the vesting of the first one-third of his 25,000 RSU award granted on March 19, 2025, which is scheduled to vest on March 19, 2026. The Company plans to launch a search for a new Chief Financial Officer immediately.
