Rhea-AI Filing Summary

Form 4 filing for Brookline Bancorp (BRKL) reports insider activity by Chairman & CEO Paul A. Perrault on 08/02/2025. Four Code “F” transactions—share withholding to satisfy tax obligations upon vesting of restricted stock—reduced his direct holdings by a total of 21,637 shares at an indicated price of $10.28.

  • 9,439 shares withheld → direct holdings 539,776
  • 3,147 shares withheld → direct holdings 536,629
  • 4,295 shares withheld → direct holdings 532,334
  • 4,756 shares withheld → direct holdings 527,578

After the transactions Perrault owns 527,578 direct shares plus 4,163 shares via ESOP and 75,000 shares via GRAT #3. The activity stems from performance-based restricted stock granted under the company’s 2021 Stock Option & Incentive Plan; no open-market buying or selling occurred. As the moves are routine tax-related withholdings and the CEO retains a substantial stake (>606 k total shares), the filing carries limited implication for Brookline Bancorp’s fundamentals.

Positive

  • None.

Negative

  • None.

Insights

TL;DR – Routine tax-withholding; neutral signal.

The Code F classification confirms these share disposals were automatic to cover taxes on vested performance RSUs, not discretionary sales. Perrault still controls roughly 1.2 % of outstanding shares, maintaining alignment with shareholders. Because there is no open-market activity, dilution, or change in incentive structure, I view the impact on valuation and sentiment as negligible.
