Immediately thereafter, Provident Bancorp merged with and into NB Bancorp (the “HoldCo Merger”), and BankProv, the wholly owned subsidiary of Provident Bancorp, merged with and into Needham Bank, the wholly owned subsidiary of NB Bancorp (the “Bank Merger” and, together with the HoldCo Merger and the Merger, the “Transaction”).

On November 17, 2025, at 12:01 a.m. Eastern Time, the Merger was consummated. Immediately thereafter, the HoldCo Merger and the Bank Merger were consummated.

Upon the terms and conditions set forth in the Merger Agreement, at the Effective Time, each share of common stock, par value $0.01 per share, of Provident Bancorp outstanding immediately prior to the Effective Time, other than certain shares held by Provident Bancorp or NB Bancorp, was converted into the right to receive, at the election of the holder, either (i) 0.691 shares of NB Bancorp common stock (the “Stock Consideration”) or (ii) $13.00 in cash (the “Cash Consideration”), subject to proration procedures to ensure that 50% of the shares of Provident Bancorp common stock are converted into the Stock Consideration. Holders of shares of Provident Bancorp common stock who receive shares of NB Bancorp common stock as a result of the Merger will receive cash in lieu of fractional shares (the Stock Consideration, the Cash Consideration and any cash in lieu of fractional shares collectively, the “Merger Consideration”).

The foregoing description of the Transaction and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K, and is incorporated herein by reference.
