Origin Bancorp (OBK) CEO logs PSU vesting and tax share withholding in Form 4

Rhea-AI Filing Summary

Origin Bancorp Chairman, President and CEO Drake Mills reported compensation-related stock activity, not open-market trading. He exercised 25,947 Performance Stock Units (PSUs) into the same number of common shares at a conversion price of $0.00 per share, increasing his direct equity stake.

To cover income tax obligations from this vesting, 10,338 common shares were withheld by the company at $48.71 per share; the filing notes this does not represent a sale. After these transactions, Mills directly holds 186,302 common shares, plus indirect holdings of 58,763 shares through an issuer retirement plan and 3,866 shares through an IRA.

The PSUs convert one-for-one into common stock and vested upon achieving a stock price hurdle of $46.25 for 20 consecutive trading days and continued employment through December 13, 2025. The filing also notes remaining PSUs eligible to vest over a seven-year performance period based on additional pre-established stock price hurdles.

Insights

Equity compensation analyst

CEO’s Form 4 shows PSU vesting and tax withholding, not market selling.

The filing shows Drake Mills converting 25,947 Performance Stock Units into common stock and the issuer withholding 10,338 shares at $48.71 per share to satisfy income tax obligations from the vesting. This is typical equity compensation mechanics rather than discretionary trading.

The PSUs vest upon achieving a stock price hurdle of $46.25 for twenty consecutive trading days and continued employment through December 13, 2025, with additional tranches tied to further stock price hurdles over a seven-year performance period. This structure links executive rewards to sustained share price performance.

Because there are no open-market purchases or sales and the remaining PSUs vest based on pre-set stock price conditions and time-based anniversaries, the informational value for short-term sentiment is limited. The filing primarily clarifies how much equity the CEO currently holds and the performance-based nature of his awards.
