Item 8.01

Other Events.

As previously announced, SI Financial Group, Inc. (“SI Financial”) and Berkshire Hills Bancorp, Inc. (“Berkshire Hills Bancorp”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which SI Financial will merge with and into Berkshire Hills Bancorp (the “Merger”). Immediately following the Merger, Savings Institute Bank and Trust Company will merge with and into Berkshire Bank (the “Bank Merger”). SI Financial (SEC File No. 000-54241) filed a definitive proxy statement/prospectus, dated as of February 25, 2019 (the “Proxy Statement/Prospectus”), with the Securities and Exchange Commission in connection with the Merger, which was first mailed to SI Financial stockholders on February 26, 2019.

On February 20, 2019, one purported SI Financial stockholder filed a putative class action lawsuit against SI Financial, Berkshire Hills Bancorp and the members of the SI Financial board of directors in the Circuit Court for Baltimore County, captioned Parshall v. Mark Alliod, et al., Docket No. C-03-CV-19-000124 (the “Complaint”). The plaintiff, on behalf of himself and similarly-situated SI Financial stockholders, generally alleges that the defendants breached their fiduciary duties to SI Financial and its stockholders in connection with the Merger Agreement. The Complaint alleges that the defendants failed to secure adequate value for SI Financial stockholders in connection with the Merger and that the registration statement filed with the Securities and Exchange Commission (the “SEC”) on February 4, 2019 contains materially incomplete information regarding the Merger. The plaintiff seeks injunctive relief, rescission of the Merger or rescissory damages (if the Merger is consummated), other unspecified damages, and an award of attorneys’ fees and expenses.

Additional Information and Where to Find It

In connection with the proposed merger, Berkshire Hills Bancorp has filed with the SEC a Registration Statement on Form S-4 (File No. 333-229506) (the “Registration Statement”) that includes a Proxy Statement of SI Financial and a Prospectus of Berkshire Hills Bancorp, and each of SI Financial and Berkshire Hills Bancorp may file with the SEC other relevant documents concerning the proposed merger. The definitive proxy statement/prospectus was first mailed to stockholders of SI Financial on or about February 26, 2019. Investors and stockholders are urged to read the Registration Statement and the Proxy Statement/Prospectus regarding the proposed merger and any other relevant documents filed with the SEC, as well as any amendments or supplements to those documents, because they will contain important information.

Copies of the Registration Statement and Proxy Statement/Prospectus and the filings that will be incorporated by reference therein, as well as other filings containing information about SI Financial and Berkshire Hills Bancorp, when they become available, may be obtained at the SEC’s Internet site (http://www.sec.gov). You will also be able to obtain these documents, free of charge, from Berkshire Hills Bancorp at www.berkshirebank.com under the tab “Investor Relations” or from SI Financial at www.mysifi.com.

SI Financial and Berkshire Hills Bancorp and certain of their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the stockholders of SI Financial in connection with the proposed merger. Information about the directors and executive officers of SI Financial is set forth in the proxy statement for the SI Financial 2018 annual meeting of stockholders, as filed with the SEC on Schedule 14A on March 29, 2018. Information about the directors and executive officers of Berkshire Hills Bancorp is set forth in the proxy statement for the Berkshire Hills Bancorp 2018 annual meeting of stockholders, as filed with the SEC on Schedule 14A on April 6, 2018.
