CENTURY BANCORP, INC. SELECTED ONE OF THE 2009 BANK & THRIFT “SM-ALL STARS”
BY SANDLER O’NEILL + PARTNERS

MEDFORD, MA, September 14, 2009 — Century Bancorp, Inc. (NASDAQ: CNBKA) the largest family-run bank in New England, today announced that it has been selected by Sandler O’Neill + Partners as one of the top performing small-cap banks in the country. The 30 institutions that comprise Sandler O’Neill’s “2009 Bank & Thrift Sm-All Stars” were chosen from a universe of 509 publicly traded banks and thrifts with market capitalizations of less than $2 billion.

According to Sandler O’Neill + Partners, the Class of 2009 “Sm-All Stars” has been identified as the next crop of leading mid-cap banks and thrifts “before they are discovered by the rest of the world.” By focusing on the institutions’ growth, profitability, credit quality and capital strength, Sandler O’Neill + Partners identified the 30 banks and thrifts, as “outstanding institutions delivering bottom line results that are markedly better than the industry as a whole.”

“We are honored to be among the 30 elite banks in the country to receive this distinction,” said Century Bank Co-President and Co-CEO, Barry R. Sloane. “We attribute our success to the values instilled by my father, Marshall M. Sloane, when he founded Century Bank in 1969 and our unwavering mission for the past 40 years to provide customers with exceptional service.”

The Sandler O’Neill + Partners survey analyzed growth, profitability, credit quality, and capital strength. Companies were evaluated based on absolute performance in eight financial variables:
(1) EPS, (2) loans, (3) deposits, (4) return on average equity, (5) nonperforming assets to loans plus OREO ratio, (6) net charge-off ratio, (7) reserve to nonperforming assets ratio and (8) Tier 1 risk-based capital ratio. To earn “Sm-All Star” status, the banks and thrifts needed to be at or above the peer median for the first seven metrics surveyed, plus be considered “Well Capitalized” per the Tier 1 risk-based capital ratio.
