ANTOLIK DAVID G 4

What Happened
David G. Antolik, President and director of S&T Bancorp, had restricted stock units vest on April 1, 2026 and those units converted/exercised into common shares. The filing shows conversions/acquisitions of 9,281 shares at a reported value of $42.28 per share (total ≈ $392,400). To cover withholding taxes on the vesting, 4,062 shares were withheld (disposed) at the same $42.28 per-share valuation (total ≈ $171,741), leaving a net delivery of roughly 5,219 shares to Mr. Antolik. The filing also records related award/derivative entries tied to performance- and time-based RSU grants.

Context
This was not an open-market purchase or sale but the vesting/conversion of restricted stock units (derivative awards). Withholding shares to cover taxes is a routine cashless mechanism and does not by itself indicate a buy/sell view by the insider. The filing documents awards tied to prior grants (including performance-based RSUs) that vested following committee determination.
