FAQ

What does the Third Coast Bancshares (TCBX) amended Form 4/A change?

The amended Form 4/A corrects an administrative error that previously showed a stock option grant to director Jeffrey A. Wilkinson. It clarifies that the reported grant did not occur and removes the erroneously reported 3,600 options from his disclosed holdings.

Did Jeffrey A. Wilkinson actually receive 3,600 stock options from TCBX?

No, the company states that the earlier Form 4 mistakenly reported a grant of 3,600 options to acquire common stock. The amended filing confirms this grant did not occur and adjusts the disclosure so no options are shown as granted on that date.

What is the purpose of this Third Coast Bancshares Form 4/A amendment?

The purpose is to correct Table II of the original Form 4, which inadvertently reported an equity award that was never granted. By filing the amendment, the company aligns its insider trading records with the actual absence of any option grant.

How many stock options does the amended TCBX filing show for the corrected grant?

The amended filing shows zero options and zero underlying common shares for the previously reported grant. This reflects that no stock option award was made to the reporting person on March 16, 2026, despite the earlier incorrect disclosure.

Who is the reporting person in the Third Coast Bancshares Form 4/A?

The reporting person is director Jeffrey A. Wilkinson. The amended Form 4 corrects prior disclosure that had mistakenly shown a stock option grant to him, confirming that the reported 3,600-option award never took place and should not be reflected in his holdings.
