BOSTON, July 24, 2025 - Berkshire Hills Bancorp, Inc. (NYSE: BHLB) today reported results for the second quarter of 2025. These results along with comparison periods are summarized below:

Berkshire CEO Nitin Mhatre stated, “Second quarter operating earnings grew 36% year-over-year due to revenue growth and lower expenses. Loans, deposits and the net interest margin increased over the linked quarter, boosting net interest income, and were accompanied by solid non-interest income growth. Quarterly operating revenue has increased sequentially over the last six quarters, growing 8% over this period, including 3% growth linked quarter. Quarterly operating income, operating EPS, and efficiency were the strongest since 2019. Second quarter 2025 operating return on tangible common equity advanced to 10.8%. TIME and Newsweek have once again honored Berkshire with national awards, the former for being one of the top-performing U.S. companies of our size and the latter for being one of the best workplaces in the financial services sector. Following months of preparation among our teams, we look forward to completing our transformative merger of equals with Brookline Bancorp and creating a powerful financial institution serving the Northeast.”

“As I reflect on our progress since we began our transformation program in early 2021, I want to express my deepest gratitude to every member of the Berkshire team, our clients and our board of directors. Our bankers’ dedication, resilience, and commitment to our clients have been the driving force behind our improved operating and financial performance. Together, we've navigated challenges, embraced change, and delivered results for our clients, shareholders and communities. I’m incredibly proud of what we’ve accomplished and excited to see what the combined company will achieve next,” added Mhatre. 

Berkshire CFO Brett Brbovic stated, “Second quarter net interest income increased 2% linked quarter and the net interest margin increased 3 basis points to 3.27%, benefiting from loan growth and lower deposit cost. Operating non-interest income increased $1.1 million linked quarter. Operating non-interest expense decreased $1.3 million linked quarter and $4.7 million year-over-year. The provision for credit losses decreased $1.5 million linked quarter and the allowance for credit losses on loans was unchanged at 1.24%. Quarterly results were very solid across the board.”

Proposed Transaction with Brookline Bancorp, Inc. On December 16, 2024, Berkshire Hills Bancorp, Inc., Commerce Acquisition Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Berkshire formed solely to facilitate the merger (“Merger Sub”) and Brookline Bancorp, Inc., a Delaware corporation (“Brookline”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into Brookline, with Brookline as the surviving entity, and immediately thereafter, Brookline will merge with and into Berkshire, with Berkshire as the surviving entity (collectively, the “Merger”). As a result of the Merger, the separate corporate existence of Brookline will cease, and Berkshire will continue as the surviving corporation. Under the terms of the Merger Agreement, which was unanimously approved by the Boards of Directors of both companies, each outstanding share of Brookline common stock will be exchanged for the right to receive 0.42 shares of Berkshire common stock. Holders of Brookline common stock will receive cash in lieu of fractional shares of Berkshire common stock. As a result of the proposed transaction and a $100 million common stock offering completed by Berkshire to support the proposed transaction, Berkshire stockholders will own approximately 55% and Brookline stockholders will own approximately 45% of the outstanding shares of the combined company. The proposed transaction is expected to close in 2025, subject to satisfaction of customary closing conditions, including receipt of required regulatory approvals. Shareholders of both companies approved merger-related proposals in May 2025.

NON-GAAP FINANCIAL MEASURES

This document contains certain non-GAAP financial measures in addition to results presented in accordance with Generally Accepted Accounting Principles (“GAAP”). These non-GAAP measures are intended to provide the reader with additional supplemental perspectives on operating results, performance trends, and financial condition. Non-GAAP financial measures are not a substitute for GAAP measures; they should be read and used in conjunction with the Company’s GAAP financial information. A reconciliation of non-GAAP financial measures to GAAP measures is provided below. In all cases, it should be understood that non-GAAP measures do not depict amounts that accrue directly to the benefit of shareholders. An item which management excludes when computing non-GAAP operating earnings can be of substantial importance to the Company’s results for any particular quarter or year. The Company’s non-GAAP operating earnings information set forth is not necessarily comparable to non-GAAP information which may be presented by other companies. Each non-GAAP measure used by the Company in this report as supplemental financial data should be considered in conjunction with the Company’s GAAP financial information.

The Company utilizes the non-GAAP measure of operating earnings in evaluating operating trends, including components for operating revenue and expense. These measures exclude amounts which the Company views as unrelated to its normalized operations. These items primarily include restructuring costs. Restructuring costs generally consist of costs and losses associated with the disposition of assets and liabilities and lease terminations, including costs related to branch consolidations.

The Company also calculates operating earnings per share based on its measure of operating earnings and diluted common shares. The Company views these amounts as important to understanding its operating trends, particularly due to the impact of accounting standards related to merger and acquisition activity. Analysts also rely on these measures in estimating and evaluating the Company’s performance. Adjustments in 2025 were primarily related to the pending merger. Adjustments in 2024 were primarily related to the pending merger, branch sales and consolidations, and loss on sale of securities.

Management believes that the computation of non-GAAP operating earnings and operating earnings per share may facilitate the comparison of the Company to other companies in the financial services industry. The Company also adjusts certain equity related measures to exclude intangible assets due to the importance of these measures to the investment community.
