Republic Airways’ Matt Koscal Appointed President and Chief Executive Officer Effective June 15, 2026

David Grizzle to Resume Role of Non-Executive Chair

CARMEL, Ind.--(BUSINESS WIRE)--Republic Airways Holdings Inc. (NASDAQ: RJET) today announced that its Board of Directors has unanimously named Matthew J. Koscal as President and Chief Executive Officer, effective June 15, 2026. Mr. Koscal, who joined Republic in 2014 and has served as President and Chief Commercial Officer since prior to the Company’s merger with Mesa Air Group in November 2025, will succeed David Grizzle, who will resume the role of non-executive Chair of the Board of Directors effective the same date.

The appointment finalizes the succession plan previously disclosed in the Company's December 2025 8-K filing, which stated the Board's expectation that Mr. Koscal would succeed Mr. Grizzle as CEO during the year ending December 31, 2026.

Mr. Grizzle was named CEO in July 2025 following the retirement of former CEO Bryan Bedford. Since then, he and Mr. Koscal have worked in close partnership to lead Republic through the Company's all-stock combination with Mesa Air Group. The transaction established Republic as one of the leading publicly traded regional airlines in the United States and operator of the world's largest Embraer jet fleet.

“Matt’s leadership in key roles at Republic over the past 12 years has set the stage for today’s announced appointment. He has brought strategic vision and execution, helping to build a world-class culture and an organization recognized for its outstanding delivery of operational excellence and client service. Through every phase of the Republic transformation, Matt has been an exceptional partner,” said Mr. Grizzle. “He’s earned the confidence of our workforce, our airline partners and our Board. I have full confidence in his leadership, and I look forward to continuing to support him as Chair.”

“David stepped into the CEO role at a critical time and guided Republic through a transformative merger, a return to the public markets, and the vital early stages of integration. I’m deeply grateful for his leadership and partnership during this journey. I’m humbled by the opportunity to lead Republic and truly excited about the incredible future we will build together with our talented team and valued partners,” said Mr. Koscal.

The Company is reiterating its guidance provided during the February 2026 earnings announcement.
