What Happened

Mark G. Ponder, Senior Executive Vice President & Chief Administrative Officer of Enterprise Financial Services Corp. (EFSC), was awarded 1,508 derivative shares on 2026-03-04. The award is reported as an acquisition (grant) at $0.00 per share (total grant value reported as $0 at issuance), i.e., a compensatory grant rather than a market purchase.

Key Details

Transaction date: 2026-03-04; Filing date: 2026-03-06 (filed within the typical two-business-day Form 4 window).
Amount: 1,508 derivative shares; Price per share at grant: $0.00; total cash exchanged at grant: $0.
Footnotes of the filing indicate these are RSU-style awards under the Company’s plans (each RSU typically converts to one share) and vest 100% in Q1 2027, subject to continued employment (see F5 & F6).
Shares owned after the transaction: not specified in the information provided.
Transaction code: A (award/grant of a derivative security).

Context

This was a compensatory grant (derivative award/RSUs), so no shares were bought or sold in the open market. RSUs convert to actual shares only upon vesting and may be subject to forfeiture if employment ends before vesting. Such grants are routine executive compensation and do not by themselves indicate an insider buying or selling for investment purposes.
