Rockville Financial, Inc. Announces Stock Repurchase Plan

ROCKVILLE, Conn., May 20, 2013 – Rockville Financial, Inc. (“Rockville Financial” or the “Company”) (NASDAQ Global Select Stock Market: “RCKB”), the holding company for Rockville Bank (the “Bank”), today announced that its Board of Directors approved a new stock repurchase program for up to 2,730,026 shares, or 10% of the current outstanding shares. Rockville also announced that the Company’s regulator, the Federal Reserve Bank of Boston, has completed its review of its stock repurchase proposal and has considered all the facts of record. Acting pursuant to authority delegated by the Board of Governors of the Federal Reserve System, the Reserve Bank does not object to the proposal, and the Company may proceed with the stock repurchase program.

The Company has nearly completed the remaining authorized repurchases under its prior program. The prior program is 88% complete and has approximately 342,000 shares remaining available for repurchase before the new program will commence.

Under the new program, repurchases may be made from time to time in open-market or negotiated transactions as deemed appropriate by the Company and will depend on market conditions. Open market purchases will be conducted in accordance with the limitations set forth in Rule 10b-18 of the Securities and Exchange Commission and other applicable legal requirements. Any repurchased shares will be held as treasury stock and will be available for general corporate purposes, including the funding of the Company’s equity incentive plan. Adoption of the program does not require the Company to purchase the authorized share amount, and the program can be modified or abandoned at any time.

“We are pleased to be announcing a new repurchase program,” stated William H. W. Crawford, IV, President and Chief Executive Officer (CEO) of Rockville Financial, Inc. “The Company obtained Board approval and regulatory non-objection for a new buyback plan prior to completing the current program in order to maintain our ability to repurchase shares in the market. Rockville is committed to delivering shareholder value and the effective and efficient use of excess capital. We view repurchases as an important capital management tool available to reach that goal.”
