Other Events

As previously reported, on June 5, 2025, NB Bancorp, Inc. (the "Company"), Needham Bank, a wholly-owned subsidiary of the Company, 1828 MS, Inc., a wholly owned subsidiary of the Company formed solely to facilitate the transaction (the "Merger Sub" and together with the Company and Needham Bank, "Needham"), Provident Bancorp, Inc. ("Provident") and BankProv, a wholly owned subsidiary of Provident, entered into an Agreement and Plan of Merger (the "Merger Agreement"). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, Needham will acquire Provident and BankProv through the merger of Merger Sub with and into Provident (the "Merger") followed as soon as reasonably practicable by the merger of Provident with and into the Company, with the Company as the surviving entity (the "Holdco Merger"). The Merger Agreement further provides that after the Holdco Merger, at a time selected by Buyer, BankProv will merge with and into Needham Bank, with Needham Bank as the surviving entity (the "Bank Merger" and, together with the Merger and the Holdco Merger, the "Transaction").

In connection with the Transaction, the Company initially filed with the U.S. Securities and Exchange Commission (the "SEC") a Registration Statement on Form S-4 on July 2, 2025. The Company filed the definitive proxy/statement prospectus with the SEC on July 30, 2025, and Provident first mailed the proxy statement/prospectus to stockholders on or about August 8, 2025.

Following the announcement of the Agreement and as of the date of this Current Report on Form 8-K, purported stockholders of Provident filed the following lawsuits in the Supreme Court of New York, County of New York, against Provident and the individual members of the Provident board of directors: (i) Clark v. Provident Bancorp, Inc., et al., Index No. 655082/2025 (August 26, 2025); and (ii) Reinhardt v. Provident Bancorp, Inc., et al., Index No. 655074/2025 (August 25, 2025) (the "Complaints"). In addition, between July 17, 2025 and September 5, 2025, Provident received a total of eight demand letters from counsel, each representing other individuals who are purported stockholders of Provident (collectively, the "Demands" and, together with the Complaints, the "Matters"). The Matters allege, among other things, that Provident and/or its directors caused a false and misleading proxy statement/prospectus relating to the Transaction to be filed with the SEC in violation of Section 14(a) of the Securities Exchange Act of 1934, as amended, and/or are liable for negligence and negligent misrepresentation and concealment under state common law.

Provident believes that the allegations in the Matters are wholly without merit, that the disclosures in the proxy statement/prospectus comply fully with applicable laws, and that no additional disclosures are required or necessary under applicable laws. However, in order to moot the disclosure claims, avoid the risk that the Matters delay or otherwise adversely affect the special meeting of the stockholders or the closing of the Transaction, and to avoid the cost and distraction of litigation, and without admitting any liability or wrongdoing, Provident is making additional disclosures as described in this Current Report on Form 8-K. Provident and its directors expressly deny that they have violated any laws, negligently misrepresented or concealed any information, or breached any fiduciary duties. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein or in the proxy statement/prospectus. To the contrary, Provident and its directors specifically deny all allegations in the Matters and that any additional disclosure in the proxy statement/prospectus was or is required.

Supplemental Disclosures to the Proxy Statement/Prospectus

The supplemental information contained in this Current Report on Form 8-K supplements the disclosures contained in the proxy statement/prospectus and should be read in conjunction with the proxy statement/prospectus, which should be read in its entirety.
