Item 4.01 Changes in Registrant’s Certifying Accountant.

On November 17, 2021, Amtech Systems, Inc. (the “Company”), upon the approval of the Company’s Audit Committee (the “Committee”) and Board of Directors, notified Mayer Hoffman McCann P.C. (“MHM”), the Company’s current independent registered public accounting firm, that it has been dismissed from that position effective immediately. The decision to dismiss MHM was made as part of a competitive bidding process to determine the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2022.

The audit reports of MHM on the Company’s consolidated financial statements as of and for the years ended September 30, 2021 and 2020 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. During the Company’s two most recent fiscal years ended September 30, 2021 and 2020, there were no (1) disagreements with MHM on any matter of accounting principles or practices, financial statement disclosures, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of MHM, would have caused MHM to make reference to the subject matter of the disagreements in connection with its reports; and (2) events of the type listed in paragraphs (A) through (D) of Item 304(a)(1)(v) of Regulation S-K.

The Company provided MHM with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (“SEC”) and requested that MHM furnish the Company with a letter addressed to the SEC stating whether or not MHM agrees with the above statements. The letter from MHM is filed with this Current Report on Form 8-K as exhibit 16.1.

On November 16, 2021, the Committee approved Grant Thornton LLP (“Grant Thornton”) as the Company's independent registered public accounting firm for the Company's fiscal year ending September 30, 2022, subject to the completion of Grant Thornton’s standard client acceptance procedures, which were completed on November 19, 2021. During the Company’s two most recent fiscal years ended September 30, 2021 and 2020, neither the Company nor anyone acting on its behalf consulted with Grant Thornton regarding either: (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement (as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K and the related instructions thereto) or a reportable event (as described in paragraph (a)(1)(v) of Item 304 of Regulation S-K).

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On November 16, 2021, as part of its periodic review of corporate governance matters, the Board of Directors (the “Board”) of Amtech Systems, Inc. (the “Company”) unanimously approved and adopted the First Amendment to Amended and Restated Bylaws of the Company (the “First Amendment”) to reinstate the right of shareholders to call a special meeting of shareholders. The following is a description of this amendment: Section 3.2 was revised to provide that record holders of shares of stock of the Company representing in the aggregate not less than 35% of the total numbers of shares of stock entitled to vote on the matter or matters to be brought before the proposed special meeting may request that the Company call a special meeting of the shareholders, subject to compliance with the notice and other requirements set forth in the applicable provisions of the Bylaws. The First Amendment approved by the Board became effective immediately upon approval.

Prior to the Company’s amendment and restatement of its Bylaw in September 2020, which, among other things, removed the right of shareholders to call a special meeting, the Bylaws provided in pertinent part that holders of not less than fifty percent (50%) of the issued and outstanding shares of the Company could demand that the Company call a special meeting of shareholders. As noted above, today’s amendment reinstates such right at the lower 35% threshold.

The foregoing description of the amendment contained in the First Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the First Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

AMTECH SYSTEMS, INC.

FIRST AMENDMENT

TO

AMENDED AND RESTATED BYLAWS

(Effective November 16, 2021)

THIS FIRST AMENDMENT TO AMENDED AND RESTATED BYLAWS (this “Amendment”) of Amtech Systems, Inc., an Arizona corporation (the “Corporation”), dated November 16, 2021, amends the Amended and Restated Bylaws of the Company (the “Bylaws”) as set forth below.

1. Capitalized terms not otherwise defined herein shall have the same meanings ascribed thereto in the Bylaws.

2. Section 3.2 of Article III of the Bylaws is hereby amended and restated in its entirety to read as follows:

“Section 3.2. Special Meetings. Except as otherwise required by law, special meetings of the shareholders for any purpose or purposes may be called by the Chairman of the Board or the Chief Executive Officer of the Corporation, and shall be called by the Chairman of the Board or the Secretary at the request in writing of a majority of the Board of Directorsor one or more record holders of shares of stock of the Corporation representing in the aggregate not less than thirty-five percent (35%) of the total number of shares of stock entitled to vote on the matter or matters to be brought before the proposed special meeting. A shareholder request for a special meeting shall be directed to the Secretary and shall be signed by each shareholder, or a duly authorized agent of such shareholder, requesting the special meeting and shall be accompanied by a notice setting forth the information required by Section 3.9 or Section 4.2 of these Bylaws, as applicable, as to any nominations proposed to be presented and any other business proposed to be conducted at such special meeting and as to the shareholder(s) requesting the special meeting. A special meeting requested by shareholders shall be held at such date, time and place (including by means of remote communication) as may be designated by the Board of Directors; provided, however, that the date of any such special meeting shall be not more than ninety (90) days after the request to call the special meeting by one or more shareholders who satisfy the requirements of this Section 3.2 is received by the Secretary. Notwithstanding the foregoing, a special meeting requested by shareholders shall not be held if: (i) the stated business to be brought before the special meeting is not a proper subject for shareholder action under applicable law, (ii) the requesting shareholder(s) have failed to comply with the applicable requirements of the Exchange Act and the rules and regulations thereunder, or (iii) the Board of Directors has called or calls for an annual meeting of shareholders to be held within ninety (90) days after the Secretary receives the request for the special meeting and the Board of Directors determines in good faith that the business of such annual meeting includes (among any other matters properly brought before the annual meeting) the business specified in the shareholder's request. A

shareholder may revoke a request for a special meeting at any time by written revocation delivered to the Secretary, and if, following such revocation, there are un-revoked requests from shareholders holding in the aggregate less than the requisite number of shares entitling the shareholders to request the calling of a special meeting, the Board of Directors, in its discretion, may cancel the special meeting. If none of the shareholders who submitted the request for a special meeting appears or sends a qualified representative to present the nominations proposed to be presented or other business proposed to be conducted at the special meeting, the Corporation need not present such nominations or other business for a vote at such meeting. Business transacted at all special meetings shall be confined to the matters stated in the notice of special meeting. Business transacted at a special meeting requested by shareholders shall be limited to the matters described in the special meeting request; provided, however, that nothing herein shall prohibit the Board of Directors from submitting matters to the shareholders at any special meeting requested by shareholders. The chair of a special meeting shall determine all matters relating to the conduct of the meeting, including, but not limited to, determining whether any nomination or other item of business has been properly brought before the meeting in accordance with these Bylaws, and if the chair should so determine and declare that any nomination or other item of business has not been properly brought before the special meeting, then such business shall not be transacted at such meeting.

3. Except as modified herein, the Bylaws of the Company remain in full force and effect as originally adopted by the board of directors of the Company.
