Air Industries Group Announces Amended and Restated Merger Agreement with Tenax Aerospace

Air Industries Group ("Air Industries" or the "Company") (NYSE:AIRI), a leading manufacturer of precision components and assemblies for aerospace and Department of War prime contractors, today announced that it and Tenax Aerospace Acquisition, LLC ("Tenax") entered into an Amended and Restated Agreement and Plan of Merger on Thursday July 2, 2026 (the "Amended Merger Agreement"). The Amended Merger Agreement supersedes the Agreement and Plan of Merger that was executed by the parties on February 16, 2026 (the "February Agreement"). The Company also announced that it intends to file a Registration Statement on Form S-4 with the Securities and Exchange Commission to register the additional shares of Air Industries common stock to be issued in connection with the merger.

The changes in the Amended Merger Agreement were primarily made to address requirements of the NYSE American Stock Exchange to ensure the continued listing of the combined company’s shares on the NYSE American Stock Exchange post-merger. The Amended Merger Agreement provides for three primary changes from the February Agreement:

1. The Amended Merger Agreement establishes a fixed "Merger Consideration" (as defined in the Amended Merger Agreement) of 126,900,000 shares of Air Industries common stock (25,380,000 shares after giving effect to the reverse stock split described below) to be issued to the holders of membership interests in Tenax and fixes the "Debt Adjusted AIR Share Price" (as defined in the Amended Merger Agreement) at $3.05 per share ($15.25 after giving effect to the reverse stock split described below). Each of the Merger Consideration and the Debt Adjusted AIR Share Price is subject to appropriate and equitable adjustment in the event of any subdivision, stock dividend or stock split, combination, recapitalization, exchange or reclassification of Air Industries common stock prior to the closing of the merger (including the reverse stock split described below).
2. The Amended Merger Agreement requires that prior to the closing of the merger, Air Industries will effect a reverse stock split of the issued and outstanding shares of Air Industries common stock at a ratio of one post-split share for every five pre-split shares, while simultaneously reducing the number of authorized shares of Air Industries common stock under the articles of incorporation of Air Industries by a corresponding factor, with any fractional share of Air Industries common stock otherwise resulting from the split rounded up to the nearest whole share.
3. The Amended Merger Agreement eliminates the tender offer contemplated by the February Agreement, under which Air Industries would have been required to purchase up to one million shares of Air Industries common stock from shareholders of record immediately prior to the closing.

Scott Glassman, Acting Chief Executive Officer of Air Industries, commented: "These amendments reflect our continued commitment to completing the merger with Tenax while ensuring the combined company satisfies the NYSE American’s listing requirements. We believe the revised agreement provides greater certainty for shareholders and positions the combined company for a successful closing."
