“I am pleased to announce that Rockville Financial, Inc. reported record first quarter earnings resulting in a 31% increase in earnings per share over the first quarter of 2012.

I would like to thank our employees for their continued commitment to delivering superior customer service, which is the driver to our success every day.”
