Insights

Republic outlines an interim CEO arrangement and planned 2026 handoff, but the board retains full discretion.

David Grizzle, non-executive chairman since 2017, stepped in as Chairman and CEO in July 2025 after the prior CEO left to become Administrator of the Federal Aviation Administration. He is expected to remain CEO while Republic proceeds with integrating Mesa Airlines following their merger transaction.

The board states it expects to promote Matthew Koscal, currently President and Chief Commercial Officer, to CEO within 2026, with Grizzle returning to a non-executive chairman role. This sketches a planned internal succession path while maintaining experienced board-level leadership during integration.

The company emphasizes that these are forward-looking plans subject to risks and uncertainties, and that the final succession decision will occur at a future, undetermined date at the board’s sole discretion. Future board actions and integration progress around the Mesa transaction will frame how and when this anticipated 2026 transition is implemented.
