Air Industries Extends Merger Timeline with Tenax Following SEC Review of Registration Statement
Air Industries Group (NYSE American: AIRI), a prominent manufacturer of precision-engineered components and assemblies for the aerospace and defense sectors, has announced an important update regarding its planned merger with Tenax Aerospace Acquisition, LLC. The company disclosed that the U.S. Securities and Exchange Commission (SEC) has informed Air Industries that it intends to review the Registration Statement on Form S-4 submitted on July 22, 2026, in connection with the proposed transaction.
Although the review is considered a standard regulatory procedure, it is expected to extend the overall timeline for completing the merger. As a result, Air Industries and Tenax have mutually agreed to amend their merger agreement by extending the transaction’s deadline, allowing additional time to complete the SEC review and satisfy all remaining regulatory and shareholder approval requirements.
The announcement underscores the companies’ continued commitment to completing the merger while ensuring full compliance with regulatory requirements.
SEC Initiates Review of Registration Statement
The Registration Statement on Form S-4 is a key filing required for mergers involving publicly traded companies. It contains comprehensive information about the transaction, including financial statements, business operations, risks, governance structures, and other material disclosures that enable shareholders to make informed decisions.
Air Industries filed its Form S-4 with the SEC on July 22, 2026, as part of the proposed merger process with Tenax Aerospace Acquisition.
The SEC has now notified the company that the filing will undergo a formal review. While such reviews are not mandatory for every filing, they are common for significant corporate transactions and are intended to ensure that all disclosures meet federal securities regulations and provide investors with complete and accurate information.
The company emphasized that it does not expect the SEC review to alter the economic structure or negotiated terms of the merger.
Instead, the primary impact is expected to be an extension of the transaction timetable while regulatory comments are addressed and the registration statement becomes effective.
Merger Deadline Extended by Sixty Days
Recognizing that the SEC review process may not conclude before the previously scheduled closing deadline, Air Industries and Tenax have agreed to modify the merger agreement.
On July 31, 2026, both parties executed an amendment to the Amended and Restated Agreement and Plan of Merger, originally dated July 2, 2026.
The amendment extends the transaction’s “Outside Date”—the final date by which the merger must be completed—from September 30, 2026, to November 30, 2026.
This additional sixty-day extension provides sufficient time to complete regulatory review, finalize required documentation, obtain shareholder approvals, and satisfy all remaining closing conditions.
The revised timeline reflects prudent transaction management rather than any substantive change to the merger itself.
Company Expects Transaction to Proceed as Planned
Air Industries indicated that it remains confident in the merger process despite the revised closing schedule.
Management believes that the SEC review is part of the normal course for many corporate transactions involving public companies and does not signal any concerns regarding the merits of the proposed combination.
The company continues working closely with regulators and advisors to respond promptly to any SEC comments so that the registration statement can become effective as quickly as possible.
Once the filing is declared effective, Air Industries plans to move forward with convening a shareholder meeting where investors will vote on the proposed merger.
Assuming shareholder approval and satisfaction of all remaining conditions, the company expects to complete the transaction before the new November 30, 2026 deadline.
Leadership Confident in Regulatory Process
Commenting on the development, Scott Glassman, Acting Chief Executive Officer of Air Industries Group, acknowledged that while the company had hoped the SEC would not conduct a formal review, the process is both common and expected in many merger transactions.
Glassman noted that SEC reviews of registration statements are standard regulatory practice and are designed to ensure that investors receive comprehensive and transparent information before voting on significant corporate actions.
He expressed confidence that the review process would be completed before the end of the third quarter of 2026.
According to Glassman, once the registration statement becomes effective, the company intends to schedule its shareholder meeting promptly and proceed toward completing the merger within the revised timeframe.
His comments reinforce management’s expectation that the merger remains on track despite the modest adjustment to the closing schedule.
Importance of the Form S-4 Review
The SEC’s review of a Form S-4 serves an important role in protecting investors during mergers and acquisitions.
The review process allows regulators to examine disclosures related to financial performance, business operations, potential risks, executive compensation, governance, and transaction structure.
If necessary, the SEC may request additional information or clarification before declaring the filing effective.
Companies typically respond to these comments by submitting amendments until all disclosure requirements have been satisfied.
Only after the registration statement becomes effective can shareholders formally vote on the proposed merger.
Because this review process can vary in duration depending on the complexity of the transaction and the nature of SEC comments, companies often build flexibility into merger agreements through provisions such as an “Outside Date.”
The extension announced by Air Industries reflects this practical approach to managing regulatory timelines.
Strategic Significance of the Tenax Merger
The proposed merger with Tenax Aerospace Acquisition represents an important strategic initiative for Air Industries.
Although the company has not indicated any changes to the transaction’s financial terms, the merger is expected to strengthen Air Industries’ long-term position within the aerospace and defense manufacturing industry.
Corporate combinations often provide opportunities to improve operational efficiency, expand manufacturing capabilities, increase financial flexibility, and enhance competitiveness within growing defense markets.
For Air Industries, completing the merger may further support its efforts to serve major aerospace manufacturers and defense contractors while pursuing future growth opportunities.
The company continues to focus on executing the transaction efficiently while maintaining normal business operations.

Looking Ahead
While the SEC’s decision to review Air Industries’ Registration Statement has modestly extended the merger timeline, company leadership remains confident that the transaction will move forward as planned. The amendment extending the outside closing date to November 30, 2026, provides additional flexibility to complete the regulatory review, secure shareholder approval, and finalize all closing requirements.
With no anticipated changes to the economic terms of the merger, Air Industries and Tenax continue working toward completing their strategic combination. As the regulatory process advances, the company remains focused on supporting its aerospace and defense customers with precision-engineered components while preparing for the next phase of its corporate growth following the anticipated merger.
