Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
On October 1, 2025, Mesa Air Group, Inc. (the “Company” or “Mesa”) received a notification letter (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company was not in compliance with Listing Rule 5620(a) (the “Annual Shareholders Meeting Rule”), which requires that for continued listing on the Nasdaq Capital Market (“Nasdaq Capital Market”), the Company must hold an annual meeting of shareholders within 12 months of the end of the Company’s fiscal year end (based on the September 30th fiscal year end, prior to Mesa’s recently announced change to a December 31 fiscal year end). The Notice is only a notification of deficiency, not of imminent delisting, and has no current effect on the listing or trading of the Company’s securities on Nasdaq Capital Market. Pursuant to Nasdaq Listing Rule 5810(c)(2)(G), the Notice states that the Company has 45 calendar days, or until November 17, 2025, to submit a plan to regain compliance with the Annual Shareholders Meeting Rule. The Company intends to submit a plan to regain compliance with the Annual Shareholders Meeting Rule within the required timeframe. After considering the Company’s plan, Nasdaq may grant the Company an exception of up to 180 calendar days from the prior fiscal year end, or until March 30, 2026, to regain compliance. There can be no assurance that Nasdaq will accept the Company’s plan or that the Company will be able to regain compliance with the Annual Shareholders Meeting Requirement or maintain compliance with any other Nasdaq requirement in the future.
Mesa has delayed the holding of its annual meeting of stockholders due to the pendency of its previously-announced proposed merger with Republic Airways Holdings Inc. (“Republic Airways”) under the Agreement, Plan of Conversion and Plan of Merger, dated as of April 4, 2025, pursuant to which Republic Airways will merge with and into Mesa (the “Merger”), with Mesa continuing as the surviving corporation following the Merger (and subsequently renamed “Republic Airways Holdings Inc.”). The Company expects the Merger to close in the fourth quarter of 2025, subject to approval by Mesa’s stockholders and the satisfaction of other customary closing conditions. Mesa has called a special meeting of its stockholders for the purpose of voting on the adoption of the merger agreement and certain other proposals to be held on November 17, 2025.
No Offer or Solicitation
This Current Report on Form 8-K is for informational purposes only and is not intended to and does not constitute, or form a part of, a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed transaction and is not intended to and does not constitute an offer to sell or the solicitation of an offer to buy, sell or solicit any securities or any proxy, vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

In connection with the proposed transaction, Mesa has filed with the Securities and Exchange Commission (“SEC”) a Form S-4/S-1 Registration Statement, which has been declared effective by the SEC and includes a proxy statement on Schedule 14A and prospectus (the “proxy statement/prospectus”). Promptly after filing the proxy statement/prospectus with the SEC on October 2, 2025, Mesa has commenced mailing of the definitive proxy statement/prospectus and a proxy card to each stockholder entitled to vote at the special meeting relating to the proposed transaction. INVESTORS AND SECURITY HOLDERS OF MESA ARE URGED TO READ THE PROXY STATEMENT/PROSPECTUS (INCLUDING ANY AMENDMENTS OR SUPPLEMENTS THERETO) AND ANY OTHER RELEVANT DOCUMENTS IN CONNECTION WITH THE TRANSACTION THAT MESA FILES WITH THE SEC WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED TRANSACTION. The proxy statement/prospectus and any other documents filed by Mesa with the SEC (when available) may be obtained free of charge at the SEC’s website at www.sec.gov or by accessing the Investor Relations section of Mesa’s website at https://investor.mesa-air.com/.
Participants in the Solicitation
Mesa and its directors and certain of its executive officers may be deemed to be participants in the solicitation of proxies from Mesa’s stockholders with respect to the Merger. Information about Mesa’s directors and executive officers and their ownership of Mesa’s securities is set forth in Mesa’s Form 10-K/A, filed with the SEC on July 11, 2025, and subsequent documents filed with the SEC.
Additional information regarding the identity of participants in the solicitation of proxies, and a description of their direct or indirect interests in the proposed transaction, by security holdings or otherwise, is set forth in the proxy statement/prospectus and other materials to be filed with the SEC in connection with the proposed transaction when they become available.
Forward-Looking Statements
This Current Report on Form 8-K may be deemed to contain forward-looking statements within the meaning of Section 27A of the Securities Act, Section 21E of the Securities Exchange Act of 1934, and the Private Securities Litigation Reform Act of 1995, as amended. These forward-looking statements include statements regarding the effects of the restatement of Mesa’s past financial statements and the filing of Mesa’s amended periodic reports. Words such as “future,” “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “may,” “might,” “predict,” “will,” “would,” “should,” “could,” “can,” “may,” or the negative or other variations thereof, and similar words or phrases or comparable terminology, are intended to identify forward-looking statements.
The forward-looking statements contained in this Current Report on Form 8-K reflect Mesa’s current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances, many of which are beyond the control of Mesa, that may cause actual results and future events to differ significantly from those expressed in any forward-looking statement, which risks and uncertainties include, but are not limited to: the ability to complete the proposed transaction on the proposed terms or on the anticipated timeline, or at all, including risks and uncertainties related to securing the necessary stockholder approval and satisfaction of other closing conditions to consummate the proposed transaction; the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement relating to the proposed transaction; risks that the proposed transaction disrupts Mesa’s current plans and operations or diverts the attention of Mesa’s management or employees from ongoing business operations; the risk of potential difficulties with Mesa’s ability to retain and hire key personnel and maintain relationships with customers and other third parties as a result of the proposed transaction; the failure to realize the expected benefits of the proposed transaction; the risk that the proposed transaction may involve unexpected costs and/or unknown or inestimable liabilities; the risk that Mesa’s business may suffer as a result of uncertainty surrounding the proposed transaction; the risk that stockholder litigation in connection with the proposed transaction may affect the timing or occurrence of the proposed transaction or result in significant costs of defense, indemnification and liability; effects relating to the announcement of the transaction or any further announcements or the consummation of the transaction on the market price of Mesa Common Stock; and Mesa’s compliance with Nasdaq listing requirements.
While forward-looking statements reflect Mesa’s good faith beliefs, they are not guarantees of future performance or events. Any forward-looking statement speaks only as of the date on which it was made. Mesa disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, of new information, data or methods, future events or other changes. For a further discussion of these and other factors that could cause Mesa’s future results to differ materially from any forward-looking statements, see the section entitled “Risk Factors” in Mesa’s Annual Report on Form 10-K for the year ended September 30, 2024, filed with the SEC on May 14, 2025, as amended by Form 10-K/A filed with the SEC on July 11, 2025, as updated by Mesa’s subsequent periodic reports filed with the SEC.
