Mitchell Mark Christopher 4

What Happened
Mitchell Mark Christopher, SVP & CFO of Frontier Group Holdings (ULCC), received 20,549 shares from the vesting/settlement of previously granted Restricted Stock Units (RSUs) on Feb 6 and Feb 8, 2026. The issuer withheld 8,989 of those shares to satisfy tax withholding obligations (cash value withheld ≈ $53,119), so the reporting person received a net 11,560 shares. The filing shows these transactions as conversions/settlements of RSUs (derivative code M) and tax withholding (code F); no shares were sold by the reporting person.

Key Details

• Transaction dates: Feb 6, 2026 and Feb 8, 2026.
• RSU conversions (M): 14,421 shares (2/6), 3,657 shares (2/8), 2,471 shares (2/8) = 20,549 total issued.
• Shares withheld for taxes (F): 6,309 shares @ $5.65 = $35,646 (2/6); 1,599 shares @ $6.52 = $10,425 (2/8); 1,081 shares @ $6.52 = $7,048 (2/8). Total cash value withheld ≈ $53,119; total withheld shares = 8,989.
• Net shares delivered to insider: 20,549 − 8,989 = 11,560 shares.
• Shares owned after transaction: not stated in the provided filing excerpt.
• Notable footnotes: settlement relates solely to vesting of previously granted RSUs (no sale by reporting person); each RSU equals one share; some footnotes indicate remaining RSUs vest in two equal annual installments beginning Feb 6, 2027, while another states the RSUs have fully vested as of Feb 8, 2026 (as reported in the filing).
• Filing: Report filed Feb 10, 2026 covering transactions on Feb 6 and Feb 8, 2026 (no indication in the filing excerpt that this was a late Form 4).

Context
These transactions are vesting and net-share-withholding events for RSUs (not open-market buys or sales). Withholding of shares to cover taxes is routine and does not represent a change in economic view; the insider did not sell shares as part of this settlement.
