Rockville Bank to Consolidate East Windsor Big Y into East Windsor Branch

ROCKVILLE, CONN., February 16, 2012 – William (Bill) H. W. Crawford, IV, President and Chief Executive Officer (CEO) of Rockville Bank and Rockville Financial, Inc. (NASDAQ Global Select Stock Market: “RCKB”) today announced that Rockville Bank has filed an application with the Connecticut State Department of Banking for approval to consolidate their East Windsor Big Y branch into the East Windsor branch at 39 Prospect Hill Road on Saturday, March 31, 2012. The Bank also will extend its hours at that location.

A personal letter has been mailed to all East Windsor Big Y customers notifying them of the consolidation and inviting them to visit the East Windsor branch at 39 Prospect Hill Road, less than a quarter of a mile away.

“We think our East Windsor Big Y customers will enjoy the additional conveniences of our traditional Prospect Hill location that include two drive-up teller windows, complimentary drinks and snacks, and a coin counting machine at our East Windsor branch,” explains William (Bill) H. W. Crawford, IV, President and Chief Executive Officer (CEO) of Rockville Bank. “Because we know our Big Y East Windsor customers enjoyed the extended supermarket hours, we’re expanding them at our East Windsor branch. We will be open later on Mondays, Tuesdays and Wednesdays until 5:00 p.m., and on Thursdays and Fridays until 7:00 p.m. The branch also is open on Saturdays from 9 a.m. to 12 noon. We want our customers to know that all of our employees at our East Windsor Big Y branch will continue to be employed at Rockville Bank, and they will see those familiar faces at other branches.”
