Insights

Bank M&A and Insider Reporting Analyst

Director’s 27,488 shares converted per merger terms; position now zero.

The filing records a Form 4 disposition triggered by the HarborOne–Eastern Bankshares merger. Each HarborOne share became the right to receive either $12.00 in cash or 0.765% of an Eastern share, subject to proration, which is typical in bank mergers.

This is an administrative conversion rather than a discretionary trade.
