Item 7.01 Regulation FD Disclosure

On October 8, 2015, Amtech Systems, Inc. (the “Company”) entered into a Letter Agreement (the “Agreement”) by and between the Company and certain shareholders of the Company who jointly file (the “Joint Filers”) under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Agreement permits the Joint Filers, pursuant to the Company’s Second Amended and Restated Rights Agreement, to individually acquire shares of common stock of the Company that would, in the aggregate, bring the Joint Filers’ collective ownership to no more than 19.9% of the Company’s issued and outstanding common stock at any time. In the event the Joint Filers’ collective ownership at any time exceeds 19.9% of the Company’s issued and outstanding shares of common stock, the Company is entitled to specific performance and all other remedies entitled to the Company at law or equity, among others. The Company’s board of directors has approved the Agreement and transactions contemplated thereunder, and has the sole authority to terminate the Agreement at any time.

A copy of the Agreement is attached hereto as Exhibit 99.1. The Agreement is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Exchange Act or otherwise subject to the liabilities of such section, nor shall such information be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
