NB Bancorp Director Reports Minor Reduction in Direct Stock Ownership
On September 10, 2025, Christopher R. Lynch—director at NB Bancorp—reduced his directly held position in the company’s common stock by 600 shares. The transaction was formally disclosed in a recent Form 4 filing with the SEC.
While the reduction was small, the filing reinforces ongoing transparency around insider holdings. After the transfer, Lynch holds 93,162 shares directly and another 60,000 shares indirectly through an IRA. The transaction was labeled as a “G” code, which generally points to a gift or transfer, not a sale. No cash exchanged hands, and the price was listed as $0.
The filing also notes that Lynch’s direct ownership includes restricted stock. These shares are scheduled to vest in annual increments of 20%, beginning in April 2026. That aligns with standard director compensation plans, which are designed to promote long-term alignment with shareholders.
NB Bancorp, which trades under the ticker NBBK , continues to report insider activity in line with regulatory requirements. For shareholders and market participants, filings like this provide added visibility into how company leadership manages their equity exposure—whether that means holding, transferring, or accumulating shares.
