On July 30, 2025, ScanTech AI Systems Inc. (the “Company”) received a deficiency letter (the “MVPHS Notice”) from Nasdaq Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that, based upon Nasdaq’s review of the Company’s market value of publicly held shares (“MVPHS”) for previous 30 consecutive business days ended July 28, 2025, the Company is not in compliance with Nasdaq Listing Rule 5450(b)(2)(C) to maintain a MVPHS of at least $15 million (the “MVPHS Requirement”).

In accordance with Nasdaq rules, the Company has a period of 180 calendar days (or until January 26, 2026) to regain compliance with the MVPHS Requirement. To regain compliance during this 180-day compliance period, the minimum MVPHS must close at $15 million or more for a minimum of 10 consecutive business days. The MVPHS Notice has no immediate effect on the listing of the Company’s common stock on The Nasdaq Global Market.

In the event that the Company does not regain compliance with the MVPHS Requirement prior to the expiration of the 180-day compliance period, the Company will receive written notification from Nasdaq that the Company’s securities are subject to delisting. The Company could then appeal such delisting determination by Nasdaq to a Hearings Panel. Alternatively, the Company may apply to transfer the listing of its securities to The Nasdaq Capital Market, provided the Company meets the continued listing requirements of The Nasdaq Capital Market.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (“Exchange Act”), including statements regarding the Company’s management team’s expectations, hopes, beliefs, intentions, plans, prospects or strategies regarding the future, including timing for possibly regaining compliance with Nasdaq listing rules including the MVPHS requirement, revenue growth and financial performance, balance sheet structuring, product expansion, and services. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Additionally, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained in this Current Report on Form 8-K are based on the current expectations and beliefs made by the management of the Company, in light of their respective experience and their perception of historical trends, current conditions and expected future developments and their potential effect on the Company, as well as other factors they believe are appropriate under the circumstances. There can be no assurance that future developments affecting the Company will be those that it has anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond the control of the parties) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements, including the Company’s ability to meet the other continued listing rules of Nasdaq or any market of Nasdaq, product and service acceptance, regulatory oversights, research and development success, and that the Company will have sufficient capital to operate as anticipated. Should one or more of these risks of uncertainties materialize, or should any of the assumptions of the Company prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Additional factors that could cause actual results to differ are discussed under the heading “Risk Factors” and in other sections of the filings of the Company (and its predecessor, Mars Acquisition Corp.) with the U.S. Securities and Exchange Commission (the “SEC”), and in the current and periodic reports filed or furnished by the Company (and its predecessor, Mars Acquisition Corp.) from time to time with the SEC. All forward-looking statements in this Current Report on Form 8-K are made as of the date hereof, based on the information available to the Company as of the date hereof, and the Company assumes no obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise, except as may otherwise be required under applicable securities laws.
