The total reported in Column 5 includes 1,483 RSA's previously reported in Table II and 8,351 shares of common stock. On November 25, 2025, Issuer and Republic Airways Holdings Inc. ("Republic") completed a stock-for-stock merger transaction (the "Merger"), pursuant to which Republic merged with and into Issuer and changed its name from Mesa Air Group, Inc to Republic Airways Holdings Inc. Prior to the closing of the Merger, Issuer effected a 15 to 1 stock split (the "Stock Split") of its common stock.

Upon the Merger, the combined company was renamed to Republic Airways Holdings Inc. and now trades under the new ticker symbol RJET. In connection with the Merger, each outstanding restricted stock unit and RSA in respect of shares of Issuer's common stock, whether vested or unvested, accelerated in full and was cancelled and converted into the right to receive a number of shares of Issuer's common stock, less any applicable withholding taxes.
