Form 4 filing for Enterprise Bancorp Inc. (EBTC) reports that director Nickolas Stavropoulos disposed of all remaining EBTC common shares on 07/01/2025 in connection with the closing of the previously-announced merger with Independent Bank Corp. (INDB).

• Direct holdings: 5,291.2761 shares were converted.

Positive

• Merger consideration delivered: each EBTC share converted into $2.00 cash plus 0.60 INDB shares, providing liquidity and upside exposure to the combined entity.

Negative

• Termination of EBTC insider ownership: directors now hold no EBTC shares, but this is mechanical due to the company’s merger-driven delisting.

Insights

Financial Analyst

TL;DR: Insider’s EBTC shares converted to cash & INDB stock; no open-market sale, neutral signal.

The Form 4 simply records automatic conversion of Mr. Stavropoulos’s 10,134.2761 EBTC shares (direct + trust) into the merger consideration. Because EBTC ceases to trade post-merger, the zero share balance is expected and does not imply insider sentiment. Investors should instead focus on INDB stock performance and projected merger synergies previously disclosed. No pricing, earnings, or new corporate guidance is provided here, so market impact is minimal.

Corporate Governance Specialist

TL;DR: Filing confirms clean Section 16 compliance on merger close; no governance red flags.

This disclosure fulfills Rule 16a obligations, demonstrating timely reporting of automatic share conversion. Footnotes clarify dividend-reinvestment accretions and accelerated vesting of restricted stock—both standard in bank M&A. No unusual compensation adjustments or side agreements appear. From a governance perspective, the transition to INDB equity is routine and well-documented.
