CENTURY BANCORP, INC. ANNOUNCES RECORD EARNINGS FOR 2019, UP 10%; ASSET GROWTH TO RECORD $5.5 BB; REGULAR DIVIDEND DECLARED

Medford, MA, January 21, 2020—Century Bancorp, Inc. (NASDAQ:CNBKA) (www.centurybank.com) (“the Company”) today announced net income of $39,699,000 for the year ended December 31, 2019, or $7.13 per Class A share diluted, an increase of 9.6% compared to net income of $36,213,000, or $6.50 per Class A share diluted, for the same period a year ago. Total assets increased 6.4% from $5.16 billion at December 31, 2018 to $5.49 billion at December 31, 2019. For the quarter ended December 31, 2019, net income totaled $10,732,000 or $1.93 per Class A share diluted, an increase of 8.1% compared to net income of $9,925,000 or $1.78 per Class A share diluted, for the same period a year ago.

Net interest income totaled $95.8 million for the year ended December 31, 2019 compared to $92.6 million for the same period in 2018. The 3.5% increase in net interest income for the period is primarily due to an increase in average earning assets. The net interest margin decreased from 2.18% on a fully taxable equivalent basis in 2018 to 2.10% for 2019. This was primarily the result of increased rates paid on deposits. The average balances of earning assets increased by $335.8 million or 7.2%, combined with an average yield increase of 0.23%, resulting in an increase in interest income of $22.1 million. The average balance of interest bearing liabilities increased by $298.1 million or 7.9%, combined with an average cost of funds increase of 0.38%, resulting in an increase in interest expense of $18.9 million.

The Company’s effective tax rate decreased from 4.2% for the year ended December 31, 2018 to 2.7% for the same period in 2019. This was primarily as a result of a reduction in tax accruals related to sequestration of the refundable portion of our alternative minimum tax (AMT) credit carryforward. On January 14, 2019, the IRS updated its announcement “Effect of Sequestration on the Alternative Minimum Tax Credit for Corporations” to clarify that refundable AMT credits under Section 53(e) of the Internal Revenue Code are not subject to sequestration for taxable years beginning after December 31, 2017. Therefore, the full amount of the AMT credit carryover will be refunded to the Company.

At December 31, 2019, total equity was $332.6 million compared to $300.4 million at December 31, 2018. The Company’s equity increased primarily as a result of earnings, offset somewhat by dividends paid.

The Company’s leverage ratio stood at 7.25% at December 31, 2019, compared to 6.91% at December 31, 2018. The increase in the leverage ratio was due to an increase in stockholders’ equity, offset somewhat by an increase in quarterly average assets. Book value as of December 31, 2019 was $59.73 per share compared to $53.96 at December 31, 2018.

The Company’s allowance for loan losses was $29.6 million or 1.22% of loans outstanding at December 31, 2019 compared to $28.5 million or 1.25% of loans outstanding at December 31, 2018. The ratio of the allowance for loan losses to loans outstanding has decreased from the same period last year, primarily as a result of improvements in historical loss rates. Non-performing assets totaled $2.0 million at December 31, 2019, compared to $3.5 million at December 31, 2018. Nonperforming assets decreased from the same period last year, mainly as a result of the resolution of one residential real estate property during the third quarter of 2019.

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 February 18, 2020 to stockholders of record on February 3, 2020.
