Item 2.01

Completion of Acquisition or Disposition of Assets.

On September 1, 2025, Brookline Bancorp, Inc., a Delaware corporation (“Brookline”), completed its previously announced merger of equals transaction with Beacon Financial Corporation, Inc., a Delaware corporation previously known as “Berkshire Hills Bancorp, Inc.” (the “Company” or “Beacon Financial”), pursuant to the Agreement and Plan of Merger, dated as of December 16, 2024, by and among the Company, Commerce Acquisition Sub, Inc. and Brookline (the “Merger Agreement”). On September 1, 2025, Commerce Acquisition Sub, Inc. merged with and into Brookline (the “Merger”), immediately followed by the merger of Brookline into the Company (the “Holdco Merger”), with the Company as the resulting corporation. The Company also changed its name from “Berkshire Hills Bancorp, Inc.” to “Beacon Financial Corporation.” Immediately following the closing of the Holdco Merger, the Company changed its New York Stock Exchange ticker symbol for its common stock, par value $0.01 per share (the “Beacon Financial Common Stock”), from “BHLB” to “BBT.” Immediately following the closing of the Holdco Merger, the Company had approximately 84,272,242 shares of common stock outstanding.

Pursuant to the terms of the Merger Agreement, as of the closing of the Holdco Merger, each share of Brookline common stock, par value $0.01 per share (“Brookline Common Stock”), was converted into the right to receive 0.42 shares of Beacon Financial Common Stock, with cash to be paid in lieu of fractional shares (the “Merger Consideration”).

Immediately following the Holdco Merger, Berkshire Bank, a wholly owned subsidiary of Beacon Financial, Bank Rhode Island, a wholly owned subsidiary of Brookline, and PCSB Bank, a wholly owned subsidiary of Brookline, each merged with and into Brookline Bank, a wholly owned subsidiary of Brookline, with Brookline Bank as the surviving bank (the “Bank Mergers” and, together with the Merger and the Holdco Merger, the “Transaction”). Effective upon the Bank Mergers, Brookline Bank changed its name to “Beacon Bank & Trust,” although it will be more commonly referred to as “Beacon Bank.”

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 Brookline’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) and is incorporated by reference into this Item 2.01.

Item 3.01

Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

In connection with the closing of the Transaction, Brookline notified the Nasdaq Stock Market LLC (“Nasdaq”) that the Transaction had closed and requested that Nasdaq (i) suspend trading of Brookline Common Stock, (ii) withdraw Brookline Common Stock from listing on Nasdaq prior to the opening of trading on September 2, 2025, and (iii) file with the SEC a notification on Form 25 of delisting of Brookline Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As a result, Brookline Common Stock is no longer listed on Nasdaq.

Additionally, Beacon Financial, as successor to Brookline, intends to file with the SEC as promptly as possible a certification on Form 15 requesting the termination of registration of Brookline Common Stock under Section 12(g) of the Exchange Act and the suspension of Brookline’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.

The information set forth in Section 2.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.01.

Item 3.03

As of the closing of the Transaction, each holder of a certificate or book-entry share representing any shares of Brookline Common Stock ceased to have any rights with respect thereto, except the right to receive the Merger Consideration as described above and subject to the terms and conditions set forth in the Merger Agreement.

The information set forth in Item 2.01, Item 3.01, Item 5.01, Item 5.02 and Item 5.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.
