CENTURY BANCORP, INC. ANNOUNCES INCREASED EARNINGS FOR Q1 2016, UP 7.0%; ASSET GROWTH TO RECORD SIZE OF $4.1 BB; REGULAR DIVIDEND DECLARED

Medford, MA, April 12, 2016—Century Bancorp, Inc. (NASDAQ:CNBKA) (www.centurybank.com) (“the Company”) today announced net income of $5,307,000 for the quarter ended March 31, 2016, or $0.95 per Class A share diluted, an increase of 7.0% compared to net income of $4,959,000, or $0.89 per Class A share diluted, for the same period a year ago. Total assets increased 2.7% from $3.9 billion at December 31, 2015 to $4.1 billion at March 31, 2016.

Net interest income totaled $17.9 million for the quarter ended March 31, 2016 compared to $16.4 million for the same period in 2015. The 8.8% increase in net interest income for the period is primarily due to an increase in average earning assets. The net interest margin increased from 2.12% on a fully taxable equivalent basis for the first quarter of 2015 to 2.18% on the same basis for 2016. This was primarily the result of an increase in rates on earning assets. The average balances of earning assets increased by 6.8% combined with a similar increase in average deposits. Also, interest expense increased 13.6% as a result of an increase in deposit balances.

The provision for loan losses increased by $250,000 from $200,000 for the quarter ended March 31, 2015 to $450,000 for the same period in 2016, primarily as a result of an increase in loan balances. The Company’s effective tax rate decreased from 4.2% in 2015 to 1.2% in 2016 primarily as a result of an increase in tax-exempt income.

At March 31, 2016, total equity was $220.8 million compared to $214.5 million at December 31, 2015. The Company’s equity increased primarily as a result of earnings and a decrease in other comprehensive loss, net of taxes, offset somewhat by dividends paid. Other comprehensive loss, net of taxes, decreased primarily as a result of a decrease in unrealized losses on securities transferred from available-for-sale to held-to-maturity, decreases in unrealized losses on securities available-for-sale, and amortization of the pension liability.

The Company’s leverage ratio stood at 6.72% at March 31, 2016, compared to 6.79% at December 31, 2015. The decrease in the leverage ratio was due to an increase in quarterly average assets, offset somewhat by an increase in stockholders’ equity. Book value as of March 31, 2016 was $39.66 per share compared to $38.53 at December 31, 2015.

The Company’s allowance for loan losses was $23.5 million or 1.34% of loans outstanding at March 31, 2016, compared to $23.1 million or 1.33% of loans outstanding at December 31, 2015 and $22.5 million or 1.68% of loans outstanding at March 31, 2015. The change in the ratio of the allowance for loan losses to loans outstanding, when compared to March 31, 2015, was primarily due to changes in portfolio composition and related methodology enhancements to address these changes. Non-performing assets totaled $1.5 million at March 31, 2016, compared to $2.3 million at December 31, 2015 and $4.3 million at March 31, 2015.

The Company’s Board of Directors voted a regular quarterly dividend of 12.00 cents ($0.12) per share on the Company’s Class A common stock, and 6.00 cents ($0.06) per share on the Company’s Class B common stock. The dividends were declared payable May 16, 2016 to stockholders of record on May 2, 2016.

The Company, through its subsidiary bank, Century Bank and Trust Company, a state chartered full service commercial bank, operating twenty-seven full-service branches in the Greater Boston area, offers a full range of Business, Personal and Institutional Services.

Century Bank and Trust Company is a member of the FDIC and is an Equal Housing Lender.
