S&T Bancorp Inc. Chief Executive Officer Christopher J. McComish, who is also a director, reported a tax-withholding disposition of 1,817 shares of common stock on February 23, 2022 at $30.81 per share, leaving 4,675 shares owned directly.

The filing outlines several restricted stock unit (RSU) awards, each representing the right to receive one share of S&T Bancorp common stock. These RSUs vest in scheduled installments beginning on April 1 of 2023, 2024, 2025, and 2026, with some tied to performance criteria measured through December 31, 2024 and confirmed on March 25, 2025.
