What Happened

• Christina Cassotis, a director of S&T Bancorp, exercised stock options (transaction code M) to acquire 1,290 shares at a strike price of $44.03 per share, for a total cash outlay of $56,799. The filing also shows a conversion/disposition entry related to the derivative and a separate grant (transaction code A) of 1,136 restricted stock units (RSUs) reported as acquired at $0.

Key Details

• Transaction date: 2026-05-12; filing date: 2026-05-14 (filed two days after the transaction).
• Option exercise: 1,290 shares acquired at $44.03 each — total ~$56,799.
• Derivative conversion/disposition: 1,290 shares reported as disposed at $0 (reflects conversion/cancellation of the derivative instrument).
• Award/grant: 1,136 RSUs reported as acquired at $0 (see footnotes).
• Shares owned after the transaction: not specified in the provided filing excerpt.
• Footnotes of note:
  • F1: Upon vesting, the RSUs automatically convert into an equal number of common shares.
  • F2: Each RSU represents a contingent right to one share of common stock.
  • F3: The RSUs vest 364 days from issuance; vested shares will be delivered upon vesting.
• Filing timeliness: appears timely (filed two days after the reported transaction).

Context

• This was an exercise of options (cash paid to cover the strike price) rather than an open-market purchase; there is no reported immediate sale of the shares acquired.
• The RSU grant is a future award that will convert to shares only after vesting in ~1 year and does not represent immediate share ownership.
