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.
