PRESIDENT’S MESSAGE

Dear Shareholders:

It is with great pleasure that I share with you the successes of United Financial Bancorp, Inc. (UBNK) and its subsidiary United Bank in this, our first, annual report as a public company. 2005 was an eventful year filled with significant accomplishments, record growth and the promise of more exciting times ahead.

          We completed our initial public offering in July, selling 7.7 million shares of common stock (representing 44.6% of the stock issued) and raising $74.8 million. Our parent company, United Mutual Holding Company, owns 53.4% of our stock and the remaining 2% was used to fund our newly formed charitable foundation. Shares of UBNK stock began trading on the NASDAQ National Market on July 13th, reaching a high of $11.90 before closing at $11.75, a nice return for those investors who purchased our stock through the offering at $10 per share. We are enthusiastic about being a public company and eager to begin deploying the capital we raised to fuel our growth in the months and years ahead.

Reflecting on Our Success

          Total assets grew to $906.5 million at December 31, 2005, an increase of 17.4% over the previous year. Loan growth was strong, with increases of $40.4 million in residential mortgages, $16.6 million in commercial loans and $6.6 million in consumer loans. We recently added two experienced lenders to our commercial lending team and we will continue to add staff as we work to grow the commercial portion of our business. We also intend to maintain our position as a premier mortgage and consumer lender in the markets we serve.

          We opened a record number of new core deposit accounts in 2005, capitalizing on our superior line of free banking products and services and taking advantage of consolidation in our marketplace to fuel increases in our deposit market share. As of June 30, 2005 (the most recent FDIC data available), United Bank ranked #3 out of the 18 banks doing business in Hampden County, with a deposit market share of 10.24%, the largest market share of community banks operating in this market. Total deposits grew to $653.6 million at year end, an increase of 6.5%.

          Use of our online banking products reached new highs last year. We now have more than 11,000 PersonalBank customers, representing 35% of our consumer checking account base, of which 53% are paying bills online. United Bank was the first community bank in the market to introduce online banking in 1997 and our commitment to this delivery channel proves to be both a convenient and efficient extension of our traditional branch network. 28% of our business checking customers are also banking online as the number of BusinessBank customers recently surpassed 1,000, of which 29% are also using online bill pay. Plans are in place to build on these successes, as we look to expand our online presence and take advantage of advancements in Internet banking technology.

Our Growing Franchise

          We introduced a number of product enhancements this year, all designed to provide value to our customers and drive new traffic into our branches. We increased the number of free items in our Free & Easy Business Checking Account to 500 per month and adjusted the tier structure in our Capital Growth Account (available to both business and consumer customers), offering customers an attractive rate of return and the flexibility of writing checks from a linked checking account. These changes, together with our competitive pricing structure, make our product line one of the most attractive in the area.

          Recognizing that convenience is an important factor in selecting a bank, we extended the hours at all of our drive-up locations last fall. They are now open from 8 a.m. to 7 p.m. on Thursdays and Fridays. We also relocated the West Springfield drive-up to a newly constructed facility with two drive-up teller lanes and a drive-up ATM. Throughout the year, our branch staff did an excellent job providing the high level of personal service for which United Bank is known throughout the region. This is evident in our ability to retain more than 90% of our consumer checking accounts annually for the last seven years. We know that service is a driving factor in customer retention and we will continue to meet, and seek to exceed, customer expectations as we focus on growing our franchise and increasing our market share.

Looking Ahead

          As we move into 2006, we will focus on the execution of our strategic plan and the expansion of our branch network, starting with the opening of new, full-service branches in Westfield and Northampton, Massachusetts. The Westfield branch, our second in this market, will enable us to offer a convenient banking location in an under-banked area of the city. Northampton, a new market for United Bank, is just eight miles from our Holyoke branch and a natural extension of our current footprint. We look forward to opening these offices in the fall of 2006 and bringing our products, services and expertise to the residents and businesses of these cities.

          Expansion, growth in deposits and loans, an increased emphasis on commercial lending, enhancements in the Financial Services area and increasing shareholder value will be the driving forces behind our actions in the year ahead. I look forward to sharing our progress and success in these areas as they occur. On behalf of the Board of Directors, I thank you for your continued interest in, and support of, our company.

Sincerely,

Richard B. Collins

President and Chief Executive Officer
