[Form 4] Enterprise Financial Services Corporation Insider Trading Activity

Rhea-AI Filing Summary

Enterprise Financial Services Corp. (EFSC) – Form 4 insider transaction

On 06/30/2025, SEVP & Chief Risk Officer Bridget Huffman acquired 243 shares of EFSC common stock through the company’s 2018 Employee Stock Purchase Plan. The purchase price was $46.84 per share (85 % of the 06/30/25 close), for an outlay of roughly $11.4 k. Following the transaction, Huffman directly owns 6,042 shares; no shares were sold.

The filing also lists previously granted equity awards: 10,334 non-qualified stock options with exercise prices between $39.50 and $57.17 expiring 2031-2035, and 2,556 restricted share units scheduled to vest 2026-2028. All derivative holdings remain unchanged.

The “J” transaction code confirms the acquisition is exempt under Rule 16b-3(c). While the dollar amount is modest, it adds to cumulative insider buying indicators and may be viewed as a marginally positive confidence signal, but it is not material to EFSC’s capital structure or near-term valuation.

Positive

• Insider purchase: Executive increased direct holdings by 243 shares, a marginal vote of confidence.
• No insider sales were reported, maintaining a net buying trend.

Negative

• Immaterial size: The $11.4 k purchase represents a negligible fraction of both insider holdings and EFSC’s float.

Insights

Securities Analyst

TL;DR: Small ESPP purchase; signals confidence but financially immaterial.

The transaction increases Huffman’s direct holdings by 4.2 % to 6,042 shares, yet represents less than 0.01 % of EFSC’s outstanding stock. No open-market buying occurred; shares were acquired at a 15 % discount under the ESPP, a routine executive benefit. Existing option and RSU schedules are unchanged and already disclosed in prior filings. From a valuation and liquidity standpoint, the event is neutral; however, incremental insider accumulation can support sentiment if repeated across management.
