Insights

Corporate governance & compliance analyst

Administrative plan blackout; standard insider trading restrictions apply.

EFSC disclosed an ERISA Section 101(i) blackout for its Incentive Savings Plan to facilitate a service provider change. During the stated window, participants cannot reallocate plan assets, obtain loans, or take distributions, which is typical during recordkeeping transitions.

Per Sarbanes‑Oxley Section 306(a) and Regulation BTR, directors and executive officers are prohibited from transactions in EFSC common stock acquired in connection with service or employment during the blackout. This limits potential conflicts while plan participants are restricted.

The filing lists the start on November 24, 2025 at 3:00 p.m. CT and an end during the week beginning January 4, 2026. Actual impact depends on participant and insider activity; subsequent company communications may provide final dates.
