Insights

Equity compensation analyst

Routine RSU vesting, tax withholding and new grants; no open‑market trades.

The filing shows Executive Vice President Stephen A. Drahnak converting restricted stock units into S&T Bancorp common shares and settling associated tax obligations by share withholding at $42.28 per share. These are standard equity-compensation mechanics rather than discretionary market purchases or sales.

According to the summary data, 5,212 shares were acquired through RSU exercises, while 2,281 shares were withheld to pay taxes. Footnotes explain that some RSUs are performance-based awards under the 2023 Long Term Incentive Plan, with performance measured between January 1, 2023 and December 31, 2025 and certified on March 24, 2026.

After these transactions, Drahnak holds 16,391.525 shares directly, plus indirect holdings through a 401(k) and for a child. No remaining derivative positions are listed, and there are no open‑market buys or sells, so this appears to be routine compensation and tax settlement with neutral investment‑thesis impact.

Restricted Stock Units financial

"Restricted Stock Units vest in three equal annual installments beginning April 1, 2024."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

performance-based restricted stock units financial

"Acquired upon achievement of certain performance criteria pursuant to the performance-based restricted stock units granted April 1, 2023."

Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.

Long Term Incentive Plan financial

"Granted April 1, 2023, under the Issuer's 2023 Long Term Incentive Plan."

A long term incentive plan is a company program that awards executives and key employees bonuses—often in stock, options, or cash—only if the business meets multi-year performance goals. It links management pay to company results—like tying a coach’s bonus to a team’s multi-season record—so investors monitor it for how leaders are motivated, potential share dilution, and signals about the company’s long-term priorities.

tax liability financial

"Shares of common stock withheld for payment of tax liability for vested and converted restricted stock units."

contingent right financial

"Each restricted stock unit represents a contingent right to receive one share of S&T Bancorp, Inc. common stock."
