Insights

Financial Analyst

TL;DR: Insider bought 29,762 EBC shares at ~$16.71, increasing direct holdings—a routine but notable insider purchase.

The reported purchase of 29,762 shares at an average price of $16.71 is a clear, non-derivative acquisition by the CEO and director. This increases his direct stake and, when combined with indirect holdings via a revocable trust and ESOP, clarifies total insider ownership levels. The filing discloses price range ($16.68–$16.81) and the precise breakdown of direct versus indirect holdings, which helps assess insider alignment with shareholders. No options or derivative transactions were reported.

Corporate Governance Expert

TL;DR: CEO/Director reported an open-market purchase and updated beneficial ownership; filing appears complete and properly executed.

The Form 4 shows the reporting person is both an officer (CEO) and a director, with the transaction reported under code P (purchase). Beneficial ownership is itemized as direct and indirect holdings, and the filing is signed by an authorized power of attorney, indicating procedural compliance.
