SAVINGS INSTITUTE BANK & TRUST SEEKS STATE CHARTER

WILLIMANTIC, CT – August 27, 2014 – SI Financial Group, Inc. (“the Company”), [Nasdaq:  SIFI] the holding company of Savings Institute Bank and Trust Company (the “Bank”), today announced that the Bank filed a notice of intent to convert from a federally-chartered savings bank to a Connecticut -chartered savings bank with the Connecticut Department of Banking on August 26, 2014. It also has filed or is in the process of filing complimentary applications and notices with the Office of the Comptroller of the Currency, Federal Deposit Insurance Corporation (“FDIC”) and Federal Reserve Bank of Boston. Assuming approvals from the required agencies, the Company will remain a savings and loan holding company regulated by the Federal Reserve, and the Bank will be a Connecticut savings bank, FDIC insured, and a member bank of the Federal Reserve.

Rheo A Brouillard, Company and Bank President and Chief Executive Officer announced “These applications will not change our business plans. This is a positive change for our Bank in light of the Dodd-Frank Act which made certain changes that removed most of the benefits of operating under a federal savings bank charter.  We also believe that there are significant advantages to operating as a community bank with a local regulator that understands and lives in our market areas in Connecticut and Rhode Island.  There will be no changes in our directors, officers or employees or in the Bank’s FDIC coverage.  Rates and terms of all loans and deposits will not change as a result of the charter conversion.  The charter change is a strategic move for the long-term benefit of our shareholders, customers and employees.”

Regulatory approval is expected before year-end.
