NB Bancorp (NASDAQ:NBBK) reported an insider purchase on March 9, 2026, when Senior Executive Vice President and Chief Financial Officer Jean-Pierre Lapointe acquired 1,000 shares of the company's common stock at $20.42 per share, a transaction valued at $20,420.
The transaction took place while NBBK stock was quoting $20.79, trading close to its 52-week high of $22.70. Analysis from InvestingPro included in public reporting indicates the shares may be undervalued based on Fair Value metrics, listing NBBK among stocks identified as most undervalued. An InvestingPro tip accompanying that assessment highlights management's active share repurchase program, which the analysis says reinforces the signal sent by insider buying.
After the purchase, Lapointe's direct ownership in NB Bancorp stands at 110,331 shares, a figure that encompasses restricted stock subject to varying vesting schedules. In addition to those direct holdings, he has indirect exposure through retirement and employee plans, owning 4,018 shares via a 401(k) and 1,779 shares via an Employee Stock Ownership Plan (ESOP).
In corporate results disclosed for fourth-quarter 2025, NB Bancorp reported net income of $7.7 million, or $0.19 per diluted share, which was below the consensus estimate of $0.21 per diluted share. Revenue for the quarter was reported at $63.2 million, exceeding expectations. Company commentary and filings attribute a significant portion of the quarter's reported results to one-time items associated with NB Bancorp's acquisition of Provident Bancorp and its subsidiary, BankProv, which closed on November 15.
On an adjusted basis that excludes acquisition-related charges, NB Bancorp reported operating net income of $21.2 million, or $0.51 per diluted share, compared with $16.0 million, or $0.45 per diluted share, in the prior quarter. The reported results included $15.7 million of merger and acquisition costs tied to the Provident deal and $2.1 million in tax expenses connected with surrendered bank-owned life insurance policies. These items account for much of the difference between the reported and adjusted numbers and underscore the financial impact of the recent acquisition.
Context and takeaway - The insider purchase by the CFO, noted alongside management share buybacks, provides a direct indicator of executive-level buying activity at a time when external analysis flags potential undervaluation. At the same time, results for the quarter were clouded by discrete acquisition expenses that materially affected reported earnings.
