Diamond Howard 4

What Happened
Diamond Howard, EVP of Legal & Corporate Affairs at Frontier Group Holdings (ULCC), had 45,512 Restricted Stock Units (RSUs settle into common shares) vest on February 1, 2026. The RSUs converted into 45,512 shares; the issuer withheld 19,911 of those shares to cover tax withholding at $4.64 per share (withheld value ≈ $92,387). The net issuance to the reporting person was the remaining shares; the filing states no shares were sold by the reporting person.

Key Details

• Transaction date: February 1, 2026; Form 4 filed February 3, 2026 (appears timely).
• Primary action: RSU settlement / conversion of derivative (code M) and tax withholding (code F).
• Shares vested/converted: 45,512 RSUs → 45,512 shares.
• Shares withheld for taxes: 19,911 at $4.64 each = $92,387 (withheld by issuer, not an open-market sale).
• Implied gross value of vested shares (using $4.64): ≈ $211,176.
• Shares owned after transaction: not specified in the provided filing excerpt.
• Notable footnotes: filing confirms this transaction solely reflects RSU settlement and withholding; remaining RSUs fully vest on February 1, 2027.

Context
This was an RSU vesting and tax-withholding event, not an open-market sale or purchase by the insider. Withholding of shares by the issuer to satisfy taxes is routine and should not be read as a directional trade. Remaining RSUs are scheduled to vest next year (Feb 1, 2027).
