May 17, 2024

PHOENIX, May 17, 2024 (GLOBE NEWSWIRE) – Mesa Air Group, Inc. (NASDAQ: MESA) (“Mesa” or the “Company”) today announced that it received a notice (“Notice”) on May 16, 2024 from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) stating that the Company is not in compliance with Nasdaq Listing Rule 5250(c)(1) (the “Listing Rule”) because the Company failed to timely file its Quarterly Report on Form 10-Q for the period ended March 31, 2024 (the “Form 10-Q”) with the Securities and Exchange Commission. The filing delay is not the result of a forthcoming restatement of the Company’s financial statements or any disagreement with the Company’s auditors.

The Notice has no immediate effect on the listing or trading of the Company’s securities on the Nasdaq Capital Market. The Notice states that, because of its prior delinquency in filing its Form 10-Q for the period ended December 31, 2023 (the “Initial Delinquent Filing”), the Company has 180 calendar days from the due date of the Initial Delinquent Filing, or August 12, 2024, to file the Form 10-Q to regain compliance.

The Company continues to work diligently to complete the Form 10-Qs for the periods ended December 31, 2023 and March 31, 2024 and plans to file both Form 10-Qs prior to August 12, 2024 to regain compliance with the Listing Rule.

This announcement is made in compliance with Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a deficiency notification.
