[Form 4/A] Enterprise Bancorp Inc. Amended Insider Trading Activity

Rhea-AI Filing Summary

Enterprise Bancorp, Inc. (EBTC) – Form 4/A insider transaction

Director Michael T. Putziger reported the issuance of 1,375 shares of EBTC common stock on 01/21/2025 at an accounting value of $29.24 per share. The shares were provided under the 2016 Stock Incentive Plan in lieu of director cash compensation, therefore they do not represent an open-market purchase.

Following the transaction, Putziger’s direct beneficial ownership increased to 208,711.8819 shares. He also holds 600.4119 shares indirectly through a trust for his granddaughter. The amendment corrects the Form 4 filed on 01/23/2025 to include shares accumulated via the company’s dividend reinvestment plan on 09/03/2024 and 12/02/2024 that had been inadvertently omitted.

No derivative securities were reported, and there were no dispositions. The filing, signed 06/26/2025, indicates continued board-level equity alignment but is routine and financially immaterial to the company’s capital structure.

Positive

• Director increased direct holdings to 208,711.8819 shares, indicating continued equity alignment.
• No insider sales were reported; the transaction consists solely of share acquisitions.

Negative

• None.

Insights

Senior Financial Analyst

TL;DR: Routine equity grant; boosts director ownership by ~0.7% but no market impact.

The amendment records 1,375 incentive shares plus previously unreported dividend reinvestment accruals. Total direct holdings rise to ~208.7 k shares. Because the acquisition is compensation-related (not open-market), signalling value is limited; nevertheless, the absence of sales supports a steady insider holding trend. Dollar value (~$40 k) is negligible relative to EBTC’s market capitalization, so valuation or liquidity effects should be minimal.
