Mesa Air Group Inc. and its subsidiary Mesa Airlines, Inc. have amended their existing Loan and Guarantee Agreement with Jefferies Capital Services, LLC, acting as lender, and The Bank of New York Mellon as agent. Under the amendment, the maturity date of the loan has been extended from October 30, 2025, to November 28, 2025, with an option for Mesa to extend it by an additional 30 days. The interest rate on the loan has been reduced to zero percent for 90 days, and certain financial covenants, including collateral coverage and liquidity tests, have been waived through the new maturity date. In connection with the amendment, Mesa Airlines deposited $31.9 million into a collateral account and pledged an aircraft engine as additional collateral. Upon full repayment of the loan at maturity, the principal amount will be reduced by $12.3 million. The changes also waive specific restrictions to facilitate Mesa's planned merger with Republic Airways Holdings Inc.
