Boston, Massachusetts (January 24, 2017): Meridian Bancorp, Inc. (the “Company” or “Meridian”) (NASDAQ: EBSB), the holding company for East Boston Savings Bank (the “Bank”) announced net income of $11.3 million, or $0.22 per diluted share, for the quarter ended December 31, 2016, up from $9.5 million, or $0.18 per diluted share, for the quarter ended September 30, 2016 and $6.9 million, or $0.13 per diluted share, for the quarter ended December 31, 2015.

The Company’s return on average assets was 1.05% for the quarter ended December 31, 2016, up from 0.94% for the quarter ended September 30, 2016 and 0.80% for the quarter ended December 31, 2015. For the year ended December 31, 2016, the Company’s return on average assets was 0.87%, up from 0.74% for the year ended December 31, 2015. The Company’s return on average equity was 7.51% for the quarter ended December 31, 2016, up from 6.39% for the quarter ended September 30, 2016 and 4.67% for the quarter ended December 31, 2015. For the year ended December 31, 2016, the Company’s return on average equity was 5.77%, up from 4.19% for the year ended December 31, 2015.

Richard J. Gavegnano, Chairman, President and Chief Executive Officer, said, “It is my great pleasure to report record net income of $34.2 million for the year 2016, up $9.6 million, or 39%, from 2015. Our net income of $11.3 million for the fourth quarter of 2016, a new quarterly record, was up $1.8 million, or 19%, from the third quarter of 2016 and $4.4 million, or 64%, from the fourth quarter of 2015. Our earnings momentum over the past year resulted from rising net interest income, driven by our strong organic growth in loans and deposits, along with increasingly favorable trends in asset quality and operating efficiency. These results are also directly related to the hard work of the entire East Boston Savings Bank team, and all of us remain committed to building on these accomplishments to further strengthen our franchise and enhance shareholder value.”

The Company’s net interest income was $33.4 million for the quarter ended December 31, 2016, up $2.1 million, or 6.8%, from the quarter ended September 30, 2016 and $6.1 million, or 22.2%, from the quarter ended December 31, 2015. The interest rate spread and net interest margin on a tax-equivalent basis were 3.09% and 3.31%, respectively, for the quarter ended December 31, 2016 compared to 3.11% and 3.32%, respectively, for the quarter ended September 30, 2016 and 3.17% and 3.39%, respectively, for the quarter ended December 31, 2015. For the year ended December 31, 2016, net interest income increased $19.7 million, or 19.1%, to $122.6 million from the year ended December 31, 2015. The net interest rate spread and net interest margin on a tax-equivalent basis were 3.13% and 3.34%, respectively, for the year ended December 31, 2016 compared to 3.09% and 3.31%, respectively, for the year ended December 31, 2015. The increases in net interest income were due primarily to loan growth, partially offset by increases in the average balances and costs of total deposits and borrowings for the quarter and year ended December 31, 2016 compared to the respective prior periods.

Total interest and dividend income increased to $41.2 million for the quarter ended December 31, 2016, up $2.8 million, or 7.4%, from the quarter ended September 30, 2016 and $8.6 million, or 26.4%, from the quarter ended December 31, 2015, primarily due to growth in the Company’s average loan balances to $3.793 billion. The Company’s yield on interest-earning assets on a tax-equivalent basis was 4.05% for the quarter ended December 31, 2016, up one basis point from the quarter ended September 30, 2016 and up two basis points from the quarter ended December 31, 2015.

Total interest expense increased to $7.8 million for the quarter ended December 31, 2016, up $712,000, or 10.0%, from the quarter ended September 30, 2016 and $2.5 million, or 47.7%, from the quarter ended December 31, 2015. Interest expense on deposits increased to $7.0 million for the quarter ended December 31, 2016, up $689,000, or 11.0%, from the quarter ended September 30, 2016 and $2.2 million, or 45.0%, from the quarter ended December 31, 2015 primarily due to growth in average total deposits to $3.343 billion and an increase in the cost of average total deposits to 0.83%. Interest expense on borrowings increased to $868,000 for the quarter ended December 31, 2016, up $23,000, or 2.7%, from the quarter ended September 30, 2016 and $368,000, or 73.6%, from the quarter ended December 31, 2015 primarily due to growth in average total borrowings to $325.4 million, partially offset by a decrease in the cost of average total borrowings to 1.06%. The Company’s cost of funds was 0.85% for the quarter ended December 31, 2016, up two basis points from the quarter ended September 30, 2016 and 10 basis points from the quarter ended December 31, 2015.

For the year ended December 31, 2016, the Company’s total interest and dividend income increased $26.4 million, or 21.4%, to $149.7 million from the year ended December 31, 2015 primarily due to growth in the average loan balances of $693.1 million, or 24.7%, to $3.495 billion, partially offset by a decrease in the yield on loans on a tax-equivalent basis of five basis points to 4.30% for the year ended December 31, 2016 compared to 4.35% for the year ended December 31, 2015. The Company’s yield on interest-earning assets on a tax-equivalent basis increased 11 basis points to 4.05% for the year ended December 31, 2016 compared to 3.94% for the year ended December 31, 2015.

Total interest expense increased $6.7 million, or 32.7%, to $27.1 million for the year ended December 31, 2016 compared to $20.5 million for the year ended December 31, 2015. Interest expense on deposits increased $5.6 million, or 30.5%, to $24.1 million for the year ended December 31, 2016 from the year ended December 31, 2015 primarily due to growth in average total deposits of $462.1 million, or 17.9%, to $3.049 billion and an increase in the cost of average total deposits of eight basis points to 0.79%. Interest expense on borrowings increased $1.0 million, or 52.8%, to $3.0 million for the year ended December 31, 2016 from the year ended December 31, 2015 primarily due to growth in average total borrowings of $131.2 million, or 89.7%, to $277.6 million, partially offset by a decrease in the cost of average total borrowings of 26 basis points to 1.09%. The Company’s cost of funds increased seven basis points to 0.82% for the year ended December 31, 2016 compared to 0.75% for the year ended December 31, 2015.

Mr. Gavegnano noted, “The robust increases in net interest income have been driven by our proven capabilities to attract and retain high quality commercial loan and core deposit relationships. Over the past five years, our net interest income has steadily risen each consecutive quarter as our total loan portfolio increased $2.6 billion, for a compounded annual growth rate of 24%, and core deposits increased $1.4 billion, for a compounded annual growth rate of 20%.”

The Company’s provision for loan losses was $1.3 million for the quarter ended December 31, 2016, up from $858,000 for the quarter ended September 30, 2016 and $544,000 for the quarter ended December 31, 2015. For the year ended December 31, 2016, the provision for loan losses was $7.2 million compared to $6.7 million for the year ended December 31, 2015. The allowance for loan losses was $40.1 million or 1.02% of total loans at December 31, 2016, compared to $38.7 million or 1.04% of total loans at September 30, 2016 and $33.4 million or 1.08% of total loans at December 31, 2015. The changes in the provision and the allowance for loan losses were based on management’s assessment of loan portfolio growth and composition changes, declines in historical charge-off trends, reductions in problem loans and other improving asset quality trends, partially offset by growth in the multi-family, commercial real estate, construction, and commercial and industrial loan categories. The changes also reflected provisions and charge-offs on a multi-family construction loan relationship of $486,000 during the third quarter of 2016 and $2.3 million during the second quarter of 2015.

Net recoveries totaled $147,000 for the quarter ended December 31, 2016, or 0.02% of average loans outstanding on an annualized basis compared to net charge-offs of $478,000 for the quarter ended September 30, 2016, or 0.05% of average loans outstanding on an annualized basis and net recoveries of $274,000 for the quarter ended December 31, 2015, or 0.04% of average loans outstanding on an annualized basis. For the year ended December 31, 2016, net charge-offs totaled $436,000, or 0.01% of average loans outstanding compared to net charge-offs of $1.7 million for the year ended December 31, 2015, or 0.06% of average loans outstanding.

Non-accrual loans were $13.4 million, or 0.34% of total loans outstanding, at December 31, 2016, down $1.8 million, or 11.6%, from September 30, 2016 and $17.9 million, or 57.1%, from December 31, 2015. The reductions in non-accrual loans were primarily due to the sale at foreclosure during the third quarter of 2016 of an $11.5 million multi-family construction loan in Boston that was originally placed on non-accrual status during the second quarter of 2015, along with steady reductions across all categories of non-accrual loans. Non-performing assets, comprised entirely of non-accrual loans, were $13.4 million, or 0.30% of total assets, at December 31, 2016, down from $15.2 million, or 0.36% of total assets, at September 30, 2016 and $31.3 million, or 0.89% of total assets, at December 31, 2015.

Mr. Gavegnano commented, “During 2016, we successfully reduced our non-performing assets to the lowest levels since before the Great Recession, while our loan charge-off rates have remained at historic lows. These results were achieved through highly selective loan underwriting, diligent credit monitoring and effective collection processes.”

Non-interest income was $5.6 million for the quarter ended December 31, 2016, up from $3.3 million for the quarter ended September 30, 2016 and $2.7 million for the quarter ended December 31, 2015 primarily due to an increase in gain on sale of securities, net. For the year ended December 31, 2016, non-interest income increased $1.2 million, or 8.8%, to $14.2 million from $13.0 million for the year ended December 31, 2015 primarily due to increases of $561,000 in customer service fees and $588,000 in gain on sales of securities, net.

Non-interest expenses were $19.8 million, or 1.84% of average assets for the quarter ended December 31, 2016, compared to $19.2 million, or 1.90% of average assets for the quarter ended September 30, 2016 and $19.2 million, or 2.24% of average assets for the quarter ended December 31, 2015. As compared to the quarter ended December 31, 2015, non-interest expenses increased $591,000, or 3.1%, primarily due to increases of $549,000 in salaries and employee benefits, $399,000 in occupancy and equipment expenses and $317,000 in professional fees, partially offset by decreases of $187,000 in marketing and advertising expenses, $107,000 in foreclosed real estate expenses and $348,000 in other general and administrative expenses. For the year ended December 31, 2016, non-interest expenses increased $4.8 million, or 6.6%, to $77.5 million from $72.7 million for the year ended December 31, 2015, primarily due to increases of $4.1 million in salaries and employee benefits, $933,000 in occupancy and equipment expenses, $332,000 in professional services and $170,000 in other general and administrative expenses, partially offset by decreases of $498,000 in marketing and advertising expenses and $204,000 in foreclosed real estate expenses. The increases in salaries and employee benefits expenses were primarily due to annual increases in employee compensation and health benefits, and expenses associated with the November 2015 grant of restricted stock and stock options to the Company’s directors, officers and employees. In addition, increases in salaries and employee benefits expenses, occupancy and equipment expenses and other general and administrative expenses reflect costs associated with two new branches opened over the past year. The decreases in marketing and advertising expenses reflect lower advertising production and direct mail costs and cost savings associated with the 2015 rebranding of the former Mt. Washington Bank Division into the East Boston Savings Bank brand. The Company’s efficiency ratio improved to 54.33% for the quarter ended December 31, 2016 from 55.81% for the quarter ended September 30, 2016 and 63.81% for the quarter ended December 31, 2015. For the year ended December 31, 2016, the efficiency ratio was 57.95% compared to 64.05% for the year ended December 31, 2015.

Mr. Gavegnano added, “Our efficiency ratio has steadily improved over the past four years from a high of 77.96% for the year 2012 to 57.95% for the year 2016, with further improvement in the ratio to 54.33% for the fourth quarter, reflecting our growth-driven rise in net interest income and prudent management of non-interest expenses. These improvements were realized during a period when we expanded our core banking franchise in the lucrative metropolitan Boston market area to 31 branches. We have opened eight new branches since the end of 2011, including the March opening in Boston’s Chinatown neighborhood, the June roll-out of our innovative mobile branch and the December addition of a second Brookline location during 2016. This expansion has enabled the Bank to attract new business and consumer relationships with the resulting gains in market share of loans and deposits.”

The Company recorded a provision for income taxes of $6.6 million for the quarter ended December 31, 2016, reflecting an effective tax rate of 37.0%, compared to $5.1 million for the quarter ended September 30, 2016, reflecting an effective tax rate of 34.9% and $3.4 million, or a 33.1% effective tax rate, for the quarter ended December 31, 2015. For the year ended December 31, 2016, the provision for income taxes was $17.9 million, reflecting an effective tax rate of 34.3%, compared to $12.0 million, or 32.7%, for the year ended December 31, 2015. The changes in the income tax provision and effective tax rate were primarily due to changes in the components of pre-tax income.

Total assets were $4.436 billion at December 31, 2016, an increase of $262.9 million, or 6.3%, from $4.173 billion at September 30, 2016 and an increase of $911.5 million, or 25.9%, from $3.525 billion at December 31, 2015. Net loans were $3.899 billion at December 31, 2016, an increase of $237.1 million, or 6.5%, from September 30, 2016 and an increase of $853.4 million, or 28.0% from December 31, 2015. Loan originations totaled $550.3 million during the quarter ended December 31, 2016 and $1.6 billion during the year ended December 31, 2016. The net increase in loans for the year ended December 31, 2016 was primarily due to increases of $482.8 million in commercial real estate loans, $189.9 million in multi-family loans, $115.4 million in commercial and industrial loans and $81.2 million in construction loans, partially offset by a decrease of $4.8 million in one- to four-family loans. These net changes exclude reclassifications during the third quarter of $44.3 million in multi-family loans and $34.5 million in commercial real estate loans to one- to four-family loans in accordance with regulatory guidance. Cash and due from banks was $236.4 million at December 31, 2016, an increase of $53.6 million, or 29.3%, from September 30, 2016 and an increase of $140.1 million, or 145.3% from December 31, 2015. Securities available for sale were $67.7 million at December 31, 2016, a decrease of $74.0 million, or 52.2%, from $141.6 million at December 31, 2015 primarily due to $56.4 million in maturities, calls and principal payments and $35.4 million in sales, partially offset by $12.5 million in purchases and $6.4 million in market value appreciation.

Total deposits were $3.476 billion at December 31, 2016, an increase of $246.3 million, or 7.6%, from $3.230 billion at September 30, 2016 and an increase of $732.8 million, or 26.7%, from $2.743 billion at December 31, 2015.

The increase for the year ended December 31, 2016 was primarily due to net income of $34.2 million, $6.0 million related to stock-based compensation plans and $3.9 million in accumulated other comprehensive income, reflecting an increase in the fair value of available-for-sale securities, partially offset by a $18.8 million repurchase of 1,337,507 shares of the Company’s common stock and four quarterly dividends of $0.03 per share totaling $6.1 million. Stockholders’ equity to assets was 13.69% at December 31, 2016, compared to 14.31% at September 30, 2016 and 16.69% at December 31, 2015.
