NB Bancorp, Inc. and Provident Bancorp, Inc. Announce Mailing of Stock/Cash Election Form

NEEDHAM, Mass. and AMESBURY, Mass., Oct. 8, 2025 /PRNewswire/ — NB Bancorp, Inc. (“Needham”) (Nasdaq: NBBK), the holding company for Needham Bank, and Provident Bancorp, Inc. (“Provident”) (Nasdaq: PVBC), the holding company for BankProv, today announced that the election form and letter of transmittal (together with the related instructions, the “Election Materials”) have been distributed to holders of Provident common stock so Provident stockholders may elect to receive either Needham common stock, cash or a combination of both upon the completion of the pending combination of Needham and Provident. 

On June 5, 2025, Needham, Needham Bank, Provident, and BankProv entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Provident will merge with and into Needham, with Needham as the surviving entity (the “Holdco Merger”), and, immediately thereafter, BankProv will merge with and into Needham Bank, with Needham Bank as the surviving entity (the “Bank Merger” and, together with the Holdco Merger, the “Merger Transaction”). 

On September 16, 2025, Provident announced that its stockholders had approved the Merger Agreement.

Needham anticipates that all required regulatory approvals will be received and all of the other closing conditions will be satisfied by November 14, 2025, and the Merger Transaction will become effective on November 15, 2025, although Needham cannot provide any assurance that all required regulatory approvals, waivers or consents will be obtained, when they will be obtained, or whether there will be burdensome conditions in the approvals or any litigation challenging the approvals.

Stock and Cash Merger Consideration
As disclosed previously, including in the definitive proxy statement/prospectus filed by Needham with the Securities and Exchange Commission (the “SEC”) on July 30, 2025 (the “proxy statement/prospectus”), at the effective time of the Holdco Merger (the “Effective Time”), shares of Provident common stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive, at the election of each Provident stockholder, and subject to the allocation, proration and other procedures specified in the Merger Agreement, either:

• 0.691 shares of Needham common stock per share of Provident common stock (“Stock Consideration”); or
  
  
• $13.00 in cash per share of Provident common stock (“Cash Consideration”).

Provident stockholders may also elect to receive a combination of Stock Consideration and Cash Consideration, subject to the allocation, proration and other procedures specified in the Merger Agreement.

The Stock Consideration and Cash Consideration are collectively referred to as the “Merger Consideration.” The receipt of the Merger Consideration will be subject in each case to applicable withholding taxes, if any, and be payable without interest.

The allocation and proration provisions in the Merger Agreement ensure that 50% of the shares of Provident common stock will receive the Stock Consideration and 50% of the shares of Provident common stock will receive the Cash Consideration. (The allocation and proration procedures specified in the Merger Agreement are summarized in the Election Materials and the definitive proxy statement/prospectus.)

Stockholder Election Process
As further described in the Election Materials, for a Provident stockholder to make a valid election, a properly completed Election Form and any Provident stock certificate(s), together with any other required documents described in the Election Materials, must be received by the Exchange Agent prior to the election deadline, which is anticipated to be 5:00 p.m. (Eastern Time) on November 7, 2025. Needham and Provident intend to announce the definitive election deadline (the “Election Deadline”) at least five business days (but not more than 15 business days) prior to the Election Deadline. Provident stockholders who hold their shares through a broker, bank, trustee or other nominee should follow the instructions of such broker, bank, trustee or other nominee as to the procedures for making elections and exchanging their shares of Provident common stock.  For shares with respect to which a Provident stockholder has made an election as of the Election Deadline, those shares may not be traded through the Effective Time. Provident Employee Stock Ownership Plan (“ESOP”) and 401(k) plan participants must make their Elections with respect to their indirect beneficial ownership of Provident common stock through the ESOP and 401(k) plans no later than 5:00 p.m. (Eastern Time) on October 31, 2025. Provident stockholders and plan participants should carefully read the Election Materials provided to them, as well as the relevant portions of the proxy statement/prospectus and the Merger Agreement, before making their elections.

Any Provident stockholder who does not make a proper election by the Election Deadline will have their shares of Provident common stock exchanged for Stock Consideration, Cash Consideration or a combination of the two depending on the valid elections of other Provident stockholders and subject to the allocation and proration procedures in the Merger Agreement.  Provident ESOP and 401(k) plan participants who do not make a proper and timely election with respect to their indirect beneficial ownership of Provident common stock through the ESOP and/or 401(k) plans will have their shares elected by the respective plan trustee in proportion to the elections made by other plan participants, subject to the allocation and proration procedures in the Merger Agreement. A Provident stockholder of shares purchased after the Election Deadline will not be permitted to submit an election with respect to those shares.

Provident stockholders who have questions about the Stockholder Election Process, want up-to-date information on the Election Deadline or wish to obtain copies of the Election Materials may contact Alliance Advisors, LLC, Needham’s information agent for the Stockholder Election Process, 150 Clove Road, Suite 400, Little Falls, NJ 07424, via telephone at (855) 206-1249, or via email at [email protected].
