Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of the conditions specified therein, Merger Sub shall be merged with and into the Company (the “Merger”), with the Company surviving as a wholly-owned subsidiary of Axcelis.   On February 6, 2026, the Company held a special meeting of stockholders (the “Special Meeting”) to consider certain proposals related to the Merger. All references in this Current Report on Form 8-K to “present in person” shall mean present at the Special Meeting either (i) virtually via the Internet or (ii) in person at the Company’s headquarter offices.   As of the close of business on December 26, 2025, the record date for the Special Meeting, there were 60,297,087 shares of the Company’s common stock, par value $0.01 per share (the “Shares”), outstanding and entitled to vote at the Special Meeting. A total of 53,889,610 Shares, representing approximately 89.37% of the voting power of the outstanding Shares entitled to vote, were present in person or represented by proxy at the Special Meeting, constituting a quorum to conduct business.   At the Special Meeting, the following proposals were considered:   1. Merger Agreement Proposal . A proposal to adopt the Merger Agreement and the transactions contemplated thereby, including the merger of Merger Sub with and into the Company, with the Company surviving as a wholly owned subsidiary of Axcelis (the “Merger Agreement Proposal”).   2. Merger Compensation Proposal . A proposal to approve, on a non-binding advisory basis, the compensation that will be paid or become payable to the named executive officers of the Company that is based on or otherwise related to the transactions contemplated by the Merger Agreement (the “Merger Compensation Proposal”).   Each proposal is described in detail in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on December 31, 2025, as supplemented on January 28, 2026 and February 2, 2026, respectively (the “Proxy Statement”). The Merger Agreement Proposal and the Merger Compensation Proposal were each approved by the requisite vote of the Company’s stockholders. The final voting results for each proposal are presented below.   Proposal 1: The Merger Agreement Proposal   Approval of the Merger Agreement Proposal required the affirmative vote of the holders of a majority of the Shares issued and outstanding and entitled to vote on the Merger Agreement Proposal as of the record date for the Special Meeting. Abstentions had the same effect as voting against the Merger Agreement Proposal. The Merger Agreement Proposal was approved.   For   Against   Abstain 53,408,907   469,828   10,875         Proposal 2: The Merger Compensation Proposal   Approval of the Merger Compensation Proposal required the affirmative vote of the holders of a majority of votes cast on the Merger Compensation Proposal. Abstentions were not considered votes cast and therefore had no effect on the outcome of the Merger Compensation Proposal. The Merger Compensation Proposal was approved.   For   Against   Abstain 53,258,029   600,723   30,858   Because none of the proposals were “routine” matters, there could be no broker non-votes occurring in connection with these proposals at the Special Meeting.   As there were sufficient votes at the time of the Special Meeting to approve the Merger Agreement Proposal and the Merger Compensation Proposal, the “Adjournment Proposal” described in the Proxy Statement was not presented at the Special Meeting.   Item 7.01. Regulation FD Disclosure.   On February 6, 2026, the Company issued a press release announcing the results of the Special Meeting.
