NB Bancorp director Mary Susan Elliott completed two purchases of company common stock totaling $217,873 across transactions in January and May 2025. The buys come amid NB Bancorp's fourth quarter 2025 results, which showed revenue above expectations but reported net income below analyst estimates due to one-time costs tied to an acquisition completed on November 15.

Key Points

  • Director Mary Susan Elliott purchased 10,000 shares at $18.72 on January 24, 2025, and 1,434 shares at $21.39 on May 2, 2025, totaling $217,873.
  • After the January buy, Elliott directly owns 115,761 shares, which include restricted stock with staggered vesting; the May purchase is recorded as indirectly owned by her spouse.
  • NB Bancorp's Q4 2025 reported net income was $7.7 million ($0.19 per diluted share), below the $0.21 consensus, while revenue of $63.2 million topped expectations; operating net income excluding one-time charges was $21.2 million ($0.51 per diluted share).

NB Bancorp, Inc. (NASDAQ:NBBK) saw insider buying by director Mary Susan Elliott in two separate transactions that together amounted to $217,873 in company shares.

On January 24, 2025, Elliott acquired 10,000 shares of NB Bancorp common stock at $18.72 per share, representing a $187,200 investment. Later, on May 2, 2025, she purchased an additional 1,434 shares at $21.39 per share, a transaction valued at $30,673. The combined value for both purchases is $217,873, with executed prices spanning $18.72 to $21.39 per share.

Following the January transaction, Elliott's direct holdings in the company rose to 115,761 shares. Those holdings include restricted stock awards that vest on varying schedules. The May transaction is recorded as shares owned indirectly by Elliott's spouse.


These insider purchases coincide with NB Bancorp's recently released fourth quarter 2025 financial results. The company reported a net income of $7.7 million, or $0.19 per diluted share, for the quarter. That figure fell short of the consensus analyst estimate of $0.21 per diluted share. Revenue for the period was $63.2 million, which exceeded expectations.

NB Bancorp identified the difference between reported and operating results as arising largely from one-time items tied to its acquisition activity. Excluding those charges, the company's operating net income for the quarter was $21.2 million, or $0.51 per diluted share. That operating result was an increase from the prior quarter's operating net income of $16.0 million, or $0.45 per diluted share.

The gap between GAAP net income and operating income reflected $15.7 million in merger and acquisition-related costs, in addition to $2.1 million in tax expenses associated with surrendered bank-owned life insurance policies. The bank said these items are connected to its acquisition of Provident Bancorp and its subsidiary BankProv, which closed on November 15.


Investors tracking insider activity and recent financial disclosures will note the timing of Elliott's purchases relative to the quarter's mixed results and the material one-time charges tied to the strategic acquisition. The reported information provides a snapshot of executive-level buying alongside the company's integration costs and reported revenue strength.

Risks

  • Reported GAAP earnings were reduced by $15.7 million in merger and acquisition expenses and $2.1 million of tax charges from surrendered bank-owned life insurance - impacts financial results for the banking sector.
  • Discrepancy between reported and operating income may complicate near-term investor assessment of profitability for regional banks and financial services firms involved in acquisitions.
  • Restricted stock vesting schedules introduce timing uncertainty in director ownership and potential future share sales, which can affect investor perceptions in the equity markets.
