Insights

Equity compensation analyst

Routine RSU vesting with tax withholding; neutral impact.

ULCC disclosed a standard equity event: 17,361 RSUs vested, with 4,991 shares withheld for taxes at $4.15. This aligns with typical executive compensation mechanics and does not involve open-market selling.

Post-transaction ownership is 13,568 shares directly. RSUs convert 1:1 to common and the remaining units fully vest on 10/25/2026, indicating a scheduled future vesting date.

There is no cash inflow to the company and no sale proceeds to the insider in this excerpt; actual market impact depends on future holder actions and is not indicated here.
