SI FINANCIAL GROUP, INC. REPORTS RESULTS FOR THE THREE AND SIX MONTHS ENDED

JUNE 30, 2018

Willimantic, Connecticut — July 25, 2018. SI Financial Group, Inc. (the “Company”) (NASDAQ Global Market: SIFI), the holding company of Savings Institute Bank and Trust Company (the “Bank”), reported net income of $3.4 million, or $0.28 diluted earnings per share, for the quarter ended June 30, 2018 versus $2.8 million, or $0.24 diluted earnings per share, for the quarter ended June 30, 2017. The Company reported net income of $5.4 million, or $0.45 diluted earnings per share, for the six months ended June 30, 2018 compared to $4.6 million, or $0.38 diluted earnings per share, for the six months ended June 30, 2017.

Net interest income increased $385,000 to $11.1 million and $812,000 to $22.0 million for the three and six months ended June 30, 2018, respectively, as compared to the same periods in 2017. Net interest income increased primarily as a result of increases in the average balance of loans and the average yield earned on loans and other interest-earning assets and a reduction in the average balance of FHLB advances, partially offset by increases in the average balance and rate paid on deposits and decreases in the average balance and yield on investment securities. The increase in yields and rates paid reflects the rising interest rate environment.

The provision for loan losses increased $118,000 and $683,000 for the three and six months ended June 30, 2018, respectively, compared to the same periods in 2017, primarily due to increases in nonperforming loans, loan charge-offs, reserves for impaired loans and an increase in commercial real estate loans, which carry a higher degree of risk than other loans held in the loan portfolio. At June 30, 2018, nonperforming loans increased to $7.9 million compared to $4.7 million at June 30, 2017, resulting from increases in nonperforming multi-family and commercial real estate, commercial business and residential real estate loans of $2.5 million, $363,000 and $275,000, respectively. Net loan charge-offs were $57,000 and $112,000 for the three and six months ended June 30, 2018, respectively, compared to net loan charge-offs of $23,000 and $3,000 for the three and six months ended June 30, 2017, respectively.

Noninterest income decreased $320,000 to $3.3 million and $435,000 to $5.7 million for the three and six months ended June 30, 2018, respectively, compared to the same periods in the prior year. The decreases were due to a pre-tax gain in May 2017 of $795,000 on the sale of the Company's trust and asset management business, partially offset by income of $684,000 resulting from the release of funds held in escrow related to the December 2016 sale of the Company's ownership interest in Vantis Life Insurance Company. Wealth management fees decreased $183,000 and $501,000 for the three and six months ended June 30, 2018, respectively, versus the comparable periods in the prior year as a result of the sale of the Company's trust and asset management business in 2017. Fees earned from mortgage banking activities decreased $122,000 and $63,000 for the three and six months ended June 30, 2018, respectively, primarily as a result of lower gains on residential fixed-rate loan sales versus the comparable periods in 2017. The cash surrender value of bank owned life insurance increased $94,000 and $179,000 for the three and six months ended June 30, 2018, respectively, compared to the same periods in the prior year resulting from the purchase of new policies in October 2017.

Noninterest expenses decreased $170,000 and $461,000 for the three and six months ended June 30, 2018, respectively, compared to the same periods in 2017. Other real estate operations decreased $224,000 and $199,000 for the three and six months ended June 30, 2018, respectively, compared to the same periods in 2017 due to the sale of four foreclosed properties held by the Bank. Outside professional

services decreased $49,000 and $94,000 for the three and six months ended June 30, 2018, respectively, versus the same periods in 2017 due to a decrease in consulting expense. Regulatory assessments decreased $53,000 and $74,000 for the three and six months ended June 30, 2018, respectively, as a result of a lower FDIC assessment rate. Computer and electronic banking expenses decreased $2,000 and $94,000 for the three and six months ended June 30, 2018, respectively, versus the comparable period in 2017 as a result of contract renegotiations with a third party provider for electronic banking services. Occupancy and equipment decreased $44,000 for the three months ended June 30, 2018, primarily due to lower lease expense versus an increase of $31,000 for the first six months of 2018 compared to 2017, primarily due to higher snow removal costs. Salaries and benefits increased $77,000 and $79,000 for the three and six months ended June 30, 2018, respectively, due to an increase in employee compensation, benefits and related taxes.

Total assets increased $14.8 million, or 0.9%, to $1.60 billion at June 30, 2018, principally due to increases of $16.1 million in net loans receivable, $3.1 million in loans held for sale and $2.9 million in cash and cash equivalents, offset by a decrease of $7.2 million in available for sale securities. The higher balance of net loans receivable reflects increases of $57.2 million, $4.3 million and $2.3 million in multi-family and commercial real estate loans, condominium association loans and construction loans, respectively, offset by decreases of $21.1 million, $15.5 million, $7.2 million and $5.0 million in residential mortgage loans, SBA and USDA guaranteed loans, timeshare loans and consumer loans, respectively. The reduction in residential mortgage loans reflects the sale of $40.9 million of long-term fixed-rate loans in the secondary market. Multi-family and commercial real estate originations increased $72.3 million for the first half of 2018 compared to the same period in 2017. Originations of commercial business loans, consumer loans and residential real estate loans decreased $14.1 million, $2.8 million and $2.7 million, respectively, during the first half of 2018 compared to the same period in 2017.

Total liabilities increased $15.1 million, or 1.1%, to $1.43 billion at June 30, 2018, primarily due to increases in deposits of $17.7 million, or 1.5%, which included increases in NOW and money market accounts of $11.8 million, certificates of deposit of $6.7 million and noninterest-bearing deposits of $2.4 million, offset by a decrease in savings accounts of $2.8 million. Although market competition has intensified, deposit growth remained strong due to competitively-priced deposit products and marketing initiatives. Borrowings decreased $6.6 million from $178.3 million at December 31, 2017 to $171.7 million at June 30, 2018, resulting from repayments of Federal Home Loan Bank advances with funds from excess deposits.

Total shareholders' equity decreased $224,000 from $168.5 million at December 31, 2017 to $168.3 million at June 30, 2018. The decrease in shareholders' equity was attributable to the repurchase of common shares totaling $3.2 million, dividends paid of $1.4 million and unrealized losses on securities included in other comprehensive income of $1.4 million, partially offset by net income of $5.4 million. At June 30, 2018, the Bank’s regulatory capital exceeded the amounts required for the Bank to be considered “well-capitalized” under applicable regulatory capital guidelines.

“We continue to have success implementing the Company's strategic plan by migrating the balance sheet to a more commercial-focused loan portfolio. Deposit and commercial loan growth, coupled with lower operating expenses, have resulted in improved earnings and earnings per share year over year," commented Rheo A. Brouillard, President and Chief Executive Officer.
