Item 7.01 Regulation FD Disclosure.

On September 24, 2026, Archer Aviation Inc. (the “Company”) issued a press release announcing the expiration of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with respect to its previously announced transaction with The Boeing Company (“Boeing”) pursuant to which the Company has agreed to acquire all of the equity interests of Wisk Aero LLC, SkyGrid, LLC, and Insitu, Inc., together with certain of their respective related entities (the “Acquisition”). Completion of the Acquisition remains subject to the satisfaction or waiver of certain other closing conditions, including receipt of certain other regulatory approvals, as described more fully in the Form 8-K filed by the Company on August 10, 2026.

A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.

The information in this Item 7.01 of this Current Report on Form 8-K is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of such section, nor shall it be deemed incorporated by reference in any filing under the Exchange Act or the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.

Forward-looking Statements

This Current Report on Form 8-K contains certain statements that are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding future events, including statements about the expected benefits of the Acquisition, the anticipated timing of the closing of the Acquisition and potential impacts on the Company’s business, and other statements that are not historical facts. These statements are based on the current expectations of the Company’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on, by any investor as a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of the Company. These forward-looking statements are only predictions and may differ materially from actual results due to a variety of factors. Factors that might cause or contribute to such differences include, but are not limited to: expected benefits from the Acquisition might not be realized within the expected time frames or at all and costs or difficulties relating to integration matters might be greater than expected; any required regulatory approvals and clearances for the Acquisition may be delayed or may not be obtained (or may result in the imposition of conditions); the other closing conditions may be delayed or may not be obtained, or the equity purchase agreement may be terminated; the Company’s or Boeing’s businesses may experience disruptions due to transaction-related uncertainty or other factors making it more difficult to maintain relationships with employees, customers, other business partners or governmental entities; the possibility that the Acquisition is more expensive to complete than anticipated; diversion of management’s attention from ongoing business operations and opportunities as a result of the Acquisition or otherwise; and those factors detailed in the Company’s filings with the SEC, including the Company’s most recent Annual Report on Form 10-K filed with the SEC. Any forward-looking statements contained herein are based on assumptions that the Company believes to be reasonable as of the date they were made. The Company undertakes no obligation to update these statements as a result of new information or future events.
