Context from recent financials
The insider purchase arrives in the wake of NB Bancorp's fourth-quarter 2025 results, which showed reported net income of $7.7 million, or $0.19 per diluted share, below the consensus estimate of $0.21 per share. Revenue for the quarter was $63.2 million, which exceeded expectations.
Management disclosed that the reported figures were materially affected by one-time items tied to the company's acquisition of Provident Bancorp and its subsidiary, BankProv, announced on November 15. Excluding those one-time charges, NB Bancorp's operating net income for the quarter was $21.2 million, or $0.51 per diluted share, up from $16.0 million, or $0.45 per diluted share, in the prior quarter.
The gap between reported and operating income primarily reflected $15.7 million of merger and acquisition costs and $2.1 million of tax expenses associated with surrendered bank-owned life insurance policies.
