Catalyst Bancorp (CLST) CEO Joseph Zanco Receives Stock Award

What Happened

Joseph B. Zanco, President & CEO and a director of Catalyst Bancorp (CLST), received stock awards reported on 2026-06-10: 5,290 shares acquired at $0.00 and an additional 13,225 shares reported as a derivative acquisition at $0.00 (total 18,515 shares). These were grants/awards under the issuer’s recognition and retention plan, not open-market purchases or option exercises.

Key Details

Transaction date: 2026-06-10; Form 4 filed 2026-06-11 (appears timely).
Price paid: $0.00 for both the direct award (5,290) and the derivative award (13,225).
Total shares granted: 18,515 (5,290 + 13,225).
Shares owned after transaction: not specified in the provided filing summary.
Vesting/other footnotes: awards are subject to multi-year vesting schedules (generally vesting at 20% per year); footnotes reference different commencement dates (including Sept 1, 2023; June 10, 2026; and June 10, 2027) and prior grant balances. The filing also notes shares allocated via the Catalyst Bank 401(k) and the ESOP since the last Form 4.
Transaction type: Award/Grant (code A) — not a sale, purchase, or option exercise.

Context

These are retention/recognition grants that vest over time and therefore do not represent an immediate market purchase or sale signal. Because the awards were granted at no cash cost, they reflect compensation/retention rather than direct CEO buying or selling of company stock. Retail investors should treat vested or upcoming vesting events as potential future supply but not as immediate insider buying sentiment.
