EARNINGS RELEASE

SI FINANCIAL GROUP, INC. REPORTS RESULTS FOR THE QUARTER AND YEAR ENDED DECEMBER 31, 2014

Willimantic, Connecticut — January 28, 2015. SI Financial Group, Inc. (the “Company”) (NASDAQ Global Market: SIFI), the holding company for Savings Institute Bank and Trust Company (the “Bank”), reported net income of $1.4 million, or $0.11 diluted earnings per share, for the quarter ended December 31, 2014 versus net income of $1.0 million, or $0.08 diluted earnings per share, for the quarter ended December 31, 2013. The Company reported net income of $4.4 million, or $0.36 diluted earnings per share, for the year ended December 31, 2014 compared to a net loss of $855,000, or $0.08 diluted loss per share, for the year ended December 31, 2013.

The acquisition of Newport Bancorp, Inc. ("Newport") in September 2013 contributed to higher net income for the quarter and year ended December 31, 2014. Lower net income for the quarter and year ended December 31, 2013 was the result of costs totaling $410,000 and $2.6 million (pre-tax), respectively, associated with the acquisition of Newport. Excluding the aforementioned costs, the Company would have reported net income of $1.3 million, or $0.11 diluted earnings per share, and $1.2 million, or $0.11 diluted earnings per share, for the quarter and year ended December 31, 2013, respectively.⁽¹⁾

Net interest income decreased $86,000 to $10.0 million and increased $9.5 million to $39.3 million for the quarter and year ended December 31, 2014, respectively, compared to the same periods in 2013. Net interest income increased for the year due to an increase in the average balance of loans outstanding and a lower cost of funds, offset by an increase in the average balance of interest-bearing liabilities, versus the comparable periods in 2013.

The provision for loan losses decreased $342,000 for the fourth quarter of 2014, compared to the same period in 2013, as a result of reductions in nonperforming loans and reserves for impaired loans. The provision for loan losses increased $220,000 for the year ended December 31, 2014, compared to the same period in 2013, primarily due to an increase in commercial loans outstanding, which carry a higher degree of risk than other loans held in the loan portfolio, offset by decreases in nonperforming loans and net loan charge-offs. At December 31, 2014, nonperforming loans totaled $5.0 million, compared to $7.0 million at December 31, 2013, primarily due to decreases in nonperforming multi-family and commercial mortgage loans of $2.1 million and residential mortgage loans of $393,000. Net loan charge-offs were $166,000 and $658,000 for the quarter and year ended December 31, 2014, respectively, consisting primarily of residential mortgage loan charge-offs. Net loan charge-offs were $92,000 and $790,000 for the quarter and year ended December 31, 2013, respectively.

Noninterest income decreased $74,000 to $2.5 million and increased $1.9 million to $10.2 million for the quarter and year ended December 31, 2014, respectively, versus the comparable periods in the prior year. Increases in service fees, the cash surrender value of bank-owned life insurance and wealth management fees contributed to higher noninterest income during 2014, offset by a decline in mortgage banking activities and a reduction in the fair value of certain derivative instruments. Services fees decreased $103,000 for the fourth quarter of 2014, compared to the fourth quarter of 2013, predominately due to lower overdraft privilege fees. Service fees increased $1.2 million for the year ended December 31, 2014 as a result of additional deposit customers from the Newport acquisition and fees associated with higher electronic banking usage, compared to the prior year. Mortgage banking fees declined $25,000 and $548,000 for the quarter and year ended December 31, 2014, respectively, due to a lower volume of residential mortgage loan sales as compared to 2013. Other noninterest income for 2014 included the

reimbursement of $250,000 in legal fees and other foreclosure expenses incurred in a prior period on two commercial loans, partially offset by an impairment charge of $175,000 to reduce the carrying value of one of the Bank's small business investment company limited partnerships. For the quarter and year ended December 31, 2013, the Company realized net losses of $236,000 and $1.2 million, respectively, primarily related to the sale of $6.0 million in collateralized debt obligations and non-agency mortgage-backed securities previously classified as substandard, offset by a gain of $201,000 on the sale of $3.0 million in commercial business loans held for investment.

Noninterest expenses decreased $302,000 for the fourth quarter of 2014 and increased $3.8 million for the year ended December 31, 2014, compared to the same periods in 2013. Excluding merger costs, noninterest expenses increased for both the quarter and year ended December 31, 2014 as a result of incremental operating costs attributable to the six branches acquired in the Newport merger. Salaries and employee benefits declined $128,000 during the fourth quarter of 2014 and increased $2.1 million for the year ended December 31, 2014 as a result of additional staff and higher benefit costs. Outside professional services expense increased primarily as a result of contractual payment obligations to former Newport officers under their noncompetition agreements. Higher other noninterest expenses for 2014 were comprised of increases in fraudulent debit card transactions of $412,000, core deposit intangible amortization of $613,000 associated with the assumption of Newport deposits and prepayment penalties totaling $110,000 for the early extinguishment of certain higher rate Federal Home Loan Bank ("FHLB") borrowings. For the comparable periods in 2013, noninterest expenses included pre-tax merger costs for the acquisition of Newport of $410,000 during the fourth quarter and $2.6 million of merger costs and $659,000 of prepayment penalties for the early extinguishment of FHLB borrowings for the year.

Total assets increased $4.2 million, or 0.3%, to $1.35 billion at December 31, 2014. Cash and cash equivalents increased $11.9 million primarily due to an increase of $13.5 million in interest-bearing assets, offset by decreases in FHLB stock of $2.8 million and net loans receivable of $2.5 million. The lower balance of net loans receivable reflects decreases in residential mortgage loans of $19.2 million and commercial business loans of $2.4 million, offset by increases in multi-family and commercial mortgage loans of $12.7 million and consumer loans of $3.9 million. Loan originations for 2014 included $63.6 million and $59.3 million in commercial and residential mortgage loans, respectively, and $28.3 million and $16.7 million in consumer loans and commercial business loans, respectively.

Total liabilities decreased $743,000, or 0.1%, at December 31, 2014. The decrease in total liabilities included decreases in borrowings of $28.0 million from $184.5 million at December 31, 2013 to $156.5 million at December 31, 2014 resulting from net repayments of FHLB advances, offset by an increase of $26.0 million in deposits. Contributing to higher deposits were increases in certificates of deposit of $26.9 million and noninterest-bearing deposits of $6.6 million, offset by a decrease of $7.0 million in NOW and money market accounts. Deposit growth remained strong due to continued marketing and promotional initiatives and competitively-priced deposit products.

Total shareholders’ equity increased $4.9 million from $152.8 million at December 31, 2013 to $157.7 million at December 31, 2014. The increase in shareholders' equity was attributable to net income of $4.4 million, an increase in unrealized gains on available for sale securities aggregating $841,000 (net of taxes) and an unrealized gain of $102,000 on an interest-rate swap derivative, offset by dividends of $1.5 million and common shares repurchased totaling $841,000. At December 31, 2014, the Bank’s regulatory capital exceeded the amounts required for it to be considered “well-capitalized” under applicable regulatory capital guidelines.

“We are pleased with our results for 2014, representing our first full year of operations following the September 2013 merger with Newport. We experienced improvement in both asset quality and our net interest margin year over year, while noninterest expenses continue to trend downward as merger-related efficiencies and other cost saving measures are realized," commented Rheo A. Brouillard, President and Chief Executive Officer.

Non-GAAP Financial Measures

We believe that certain non-GAAP financial measures provide investors with information useful in understanding our financial performance, our performance trends and financial position. Specifically, we provide measures based on what we believe are our operating earnings on a consistent basis and exclude non-core operating items which affect the GAAP reporting of results of operations. We, as well as securities analysts, investors and other interested parties, use these measures to compare peer company operating performance. We believe that our presentation and discussion, together with the accompanying reconciliations, provide a complete understanding of factors and trends affecting our business and allows investors to view performance in a manner similar to management. These non-GAAP measures should not be considered a substitute for GAAP basis measures and results, and we strongly encourage investors to review our consolidated financial statements in their entirety and not to rely on any single financial measure. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.
