SI FINANCIAL GROUP, INC. REPORTS RESULTS FOR THE QUARTER AND YEAR ENDED DECEMBER 31, 2018

Willimantic, Connecticut — February 27, 2019. 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 $1.5 million, or $0.13 diluted earnings per share, for the quarter ended December 31, 2018 versus a net loss of $1.6 million, or $0.13 diluted loss per share, for the quarter ended December 31, 2017. The Company reported net income of $9.6 million, or $0.80 diluted earnings per share, for the year ended December 31, 2018 compared to $5.2 million, or $0.44 diluted earnings per share, for the year ended December 31, 2017.

Excluding pre-tax costs of $1.1 million associated with the pending merger with Berkshire Hills Bancorp, Inc. ("Berkshire"), the Company would have reported net income of $2.4 million and $10.4 million, or $0.20 and $0.88 diluted earnings per share, for the quarter and year ended December 31, 2018, respectively.⁽¹⁾ The Company anticipates the merger with Berkshire to be completed in the second quarter of 2019, subject to regulatory and shareholder approvals and other customary closing conditions. The net loss for the quarter and lower net income for the year ended December 31, 2017 was related to a charge to income tax expense of $4.0 million as a result of the revaluation of the Company's net deferred tax asset due to the passage of the Tax Cuts and Jobs Act on December 22, 2017, which reduced the corporate income tax rate from 35% to 21%. This charge was recorded as additional income tax expense in the Company's statement of income for the quarter ended December 31, 2017. Excluding the aforementioned charge to income tax expense in 2017, the Company would have reported net income of $2.4 million and $9.2 million, or $0.20 and $0.77 diluted earnings per share, for the quarter and year ended December 31, 2017, respectively.⁽¹⁾

Net interest income increased $804,000 to $11.7 million and $2.2 million to $45.1 million for the quarter and year ended December 31, 2018, respectively, compared to the same periods in 2017. Higher net interest income was due to increases in the average balance of loans and the average yield earned on loans and other interest-earning assets and a decrease in the average balance of borrowings, partially offset by a higher average balance of deposits, increases in the average rates paid on deposits and borrowings and a decrease in the average balance of other interest-earning assets.

The provision for loan losses increased $961,000 and $2.5 million for the quarter and the year ended December 31, 2018, respectively, compared to the same periods in 2017. The increase was primarily due to increases in nonperforming loans, net loan charge-offs and reserves for impaired loans and an increase in commercial loans, which carry a higher degree of risk than other loans held in the loan portfolio. At December 31, 2018, nonperforming loans totaled $9.8 million, compared to $6.4 million at December 31, 2017, resulting from increases in nonperforming multi-family and commercial real estate and residential real estate loans of $1.6 million and $1.3 million, respectively. Net loan charge-offs were $666,000 and $795,000 for the quarter and year ended December 31, 2018, respectively, consisting primarily of commercial business loan charge-offs. Net loan charge-offs for the quarter and year ended December 31, 2017 were $43,000 and $147,000, respectively.

Noninterest income increased $109,000 and $78,000 to $2.6 million and $11.2 million for the quarter and year ended December 31, 2018, respectively, versus the comparable periods in the prior year primarily due to increases in service fees and other noninterest income, offset by decreases in fees from mortgage banking activities and wealth management fees. Service fees increased $181,000 and $233,000 for the

quarter and year ended December 31, 2018, respectively, compared to the same periods in 2017, primarily due to a higher volume of overdraft and electronic banking charges. Other noninterest income increased $140,000 and $534,000 for the quarter and year ended December 31, 2018, respectively, primarily due to swap fees from interest rate swap agreements of $124,000 and $781,000 and profit distributions from our investment in three small business investment companies of $55,000 and $127,000 for the quarter and year ended December 31, 2018, respectively. Other noninterest income in 2017 included a pre-tax gain of $795,000 on the sale of the Company's trust and asset management business in May 2017. As a result of the sale, wealth management fees decreased $7,000 and $523,000 for the quarter and year ended December 31, 2018, respectively, compared to the same periods in 2017. Fees earned from mortgage banking activities decreased $219,000 and $458,000 for the quarter and the year ended December 31, 2018, respectively, due to decreased volume on residential fixed-rate loan sales.

Noninterest expenses increased $1.4 million and $1.3 million for the quarter and year ended December 31, 2018, respectively, compared to the same periods in 2017. Contributing to the increase in noninterest expenses were pre-tax merger-related transaction costs of $1.1 million for both the quarter and year ended December 31, 2018, associated with the pending merger with Berkshire. Salaries and employee benefits increased $448,000 and $861,000 for the fourth quarter and the year ended December 31, 2018, respectively, as compared to the same periods in 2017, primarily attributable to an increase in salaries and related compensation, benefits and taxes. Marketing expenses increased $122,000 and $208,000 for the quarter and year ended December 31, 2018, respectively, due primarily to focused commercial banking and cash management marketing initiatives. Compared to the same periods in 2017, other real estate operations decreased $243,000 and $456,000 for the quarter and year ended December 31, 2018, respectively, due to lower holding costs related to the other real estate properties and the sale of five foreclosed properties held by the Bank during 2018. Professional services decreased $14,000 and $219,000 for the quarter and year ended December 31, 2018, respectively, primarily due to a decrease in legal expense, partially offset by an increase in audit fees.

Total assets increased $68.9 million, or 4.4%, to $1.65 billion at December 31, 2018, principally due to increases of $75.4 million in net loans receivable and $4.4 million in cash and cash equivalents, offset by a decrease of $10.2 million in available for sale securities. The higher balance of net loans receivable reflects increases in multi-family and commercial real estate loans of $86.9 million, construction loans of $14.6 million, medical loans of $9.7 million, condominium association loans of $8.8 million and other commercial business loans of $8.7 million, offset by decreases in SBA and USDA guaranteed loans of $21.0 million, residential real estate loans of $12.9 million and time share loans of $11.1 million. Compared to 2017, commercial real estate and commercial business loan originations increased $105.3 million and $6.3 million, respectively, while residential real estate and consumer loan originations both decreased $5.0 million during 2018. The decrease in available for sale securities during 2018 was due to maturities used to fund loan growth.

Total liabilities increased $65.2 million, or 4.6%, to $1.48 billion at December 31, 2018. Deposits increased $80.0 million, or 6.6%, during 2018 due to increases in certificates of deposit of $69.6 million and noninterest bearing deposits of $29.2 million, offset by decreases in NOW and money market deposits of $10.5 million and savings accounts of $8.3 million. Deposit growth remained strong due to competitive products offered and cash management initiatives. The increase in deposits was offset by a decrease of $18.3 million in borrowings, from $178.3 million at December 31, 2017 to $160.1 million at December 31, 2018, resulting from repayments of Federal Home Loan Bank advances with funds from excess deposits.

Total shareholders’ equity increased $3.6 million from $168.5 million at December 31, 2017 to $172.1 million at December 31, 2018. The increase in shareholders' equity was attributable to net income of $9.6 million, offset by an increase in the net unrealized loss on available for sale securities of $704,000 (net of taxes), and dividends declared of $2.8 million. At December 31, 2018, the Bank’s regulatory capital exceeded the amounts required for it to be considered “well-capitalized” under applicable regulatory capital guidelines.

“Deposit and loan growth during 2018 continued to drive performance as core banking results once again improved year over year. These improvements reflect management’s efforts in key areas such as growing low-cost demand deposits, reducing wholesale funding and expense control as evidenced by a slightly higher net interest margin and a lower efficiency ratio," 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 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.

⁽¹⁾The table below presents a reconciliation of net income (loss) and earnings (loss) per share to shareholders, excluding the tax-affected transaction costs related to the pending merger with Berkshire for the quarter and year ended December 31, 2018 and the revaluation of the deferred tax asset for the quarter and year ended December 31, 2017.
