Form 4 filing overview: Mesa Air Group (ticker MESA) reports that President & Chief Financial Officer Michael Lotz acquired 69,064 common shares on 18 June 2025. The transaction is coded “M,” indicating the conversion of a derivative security—specifically the first tranche of a restricted-stock award granted on 18 June 2024 under the company’s 2018 Equity Incentive Plan.
Resulting ownership: Following the conversion, Lotz now directly owns 578,134 common shares and continues to hold 303,784 restricted-stock units (RSUs) that remain un-converted.
Award structure & future vesting: • Total original RSU grant: 207,191 shares. • Tranche schedule: 69,063 shares vest on 18 June 2026 and 69,064 on 18 June 2027. • The plan allows accelerated vesting upon a change of control, including the pending merger with Republic Airways Holding Inc.
Investor takeaways:
- The acquisition adds roughly 13% to Lotz’s previously reported direct share count, marginally increasing insider ownership.
- Because the shares were delivered at a $0 exercise price, the transaction does not represent an open-market cash purchase; its signalling value is therefore limited.
- The change-of-control clause confirms that, if the Republic Airways deal closes before 2027, remaining tranches could vest sooner, potentially increasing insider liquidity.
Form 4 filing summary – Mesa Air Group, Inc. (MESA)
Executive Vice President, General Counsel and Secretary Brian S. Gillman reported the vesting and automatic conversion of 23,504 restricted stock units (RSUs) into common shares on 18 June 2025 (Transaction Code M). The RSUs carried a $0 exercise price and stem from a 70,510-share award granted on 18 June 2024 under the company’s 2018 Equity Incentive Plan.
- Post-transaction ownership: 155,530 common shares held directly.
- Remaining unvested derivative securities: 102,998 RSUs.
- Future vesting schedule: two equal tranches of 23,503 shares on 18 June 2026 and 18 June 2027, respectively.
- Acceleration clause: Vesting may accelerate upon a change-of-control event, specifically the pending merger with Republic Airways Holding Inc. if consummated before scheduled vesting.
No open-market purchase or sale occurred; the transaction reflects routine equity compensation vesting. The filing offers a small signal of insider equity alignment and highlights the potential timing implication of the announced merger.
