East Boston Savings Bank plans to open new branches in Cambridge and Brighton in 2019, bringing the bank up to 40 branches, as it continues to use de novo branches to drive growth.

“We expect our entry into these attractive communities will lead to new business and consumer relationships and increase our market share in the Boston metropolitan area, with only minor increases to our operating expenses,” Richard J. Gavegnano, chairman, president and CEO of the bank, said in a statement.

East Boston Savings Bank opened four branches in 2018 in Lynnfield, Burlington and two in Boston on Tremont Street and Beacon Street. The bank has opened 17 new branches since 2010, according to the FDIC, and currently lists 36 branches on its website, plus a mobile branch and its corporate headquarters.

In the first quarter of 2019, the parent company of East Boston Savings Bank reported net income of $15.1 million, or $0.29 per diluted share, compared to $12 million, or $0.23 per diluted share, for the first quarter of 2018. Net interest income for the quarter was $42.6 million, up $2.7 million, or 6.9 percent, from the first quarter of 2018. The margin ended the quarter at 2.89 percent, down 27 basis points from one year ago.

Total deposits grew $834 million year-over-year to more than $5 billion, while total loans grew to roughly $5.7 billion, up more than $800 million year-over-year. The loan growth was led by commercial real estate, but every loan category grew on an annual basis.

The company’s provision for loan losses was $843,000 for the first quarter, down from $1.3 million from the first quarter of 2018. Non-performing assets as a percentage of total assets in the first quarter was 0.12 percent, down three basis points from the first quarter of 2018.
