Legacy Bancorp, Inc. Reports Results for Quarter Ended March 31, 2010

PITTSFIELD, MASSACHUSETTS (April 28, 2010): Legacy Bancorp, Inc. (the “Company” or “Legacy”) (NASDAQ: LEGC), the holding company for Legacy Banks (the “Bank”), today reported a net loss of $1.2 million or $0.15 per diluted share for the quarter ended March 31, 2010, compared to a net loss of $792,000 or $0.10 per diluted share in the first quarter of 2009. The first quarter decrease was the result of an increase in the provision for loan losses, partially offset by a decrease in charges on investments deemed to be other-than-temporarily impaired (OTTI). The total shares outstanding resulted in a book value per share and tangible book value per share of $13.80 and $12.40, respectively, at March 31, 2010.

J. Williar Dunlaevy, Chief Executive Officer, commented “While we are disappointed to start off 2010 by reporting a net loss, there are also some bright and encouraging components within our report for the first quarter.

“We continue to be disciplined each and every quarter in assessing credit quality. Individuals and businesses continue to face economic challenges from the recession. While there have been some positive signals, both locally and nationally, unemployment and weak job growth remain major concerns. They impact both borrowers and property valuation. The result is that in the first quarter we added to our loan loss reserves and also took charge-offs against certain non-performing loans. While these charge-offs have lowered the overall reserve ratio to 1.25%, much of those amounts were reserved for in previous quarters. As a result of the charges taken, the levels of non-performing loans and assets declined significantly. Legacy will continue to identify and work problem loan situations diligently.

“On the positive side, we are very pleased with the deposit growth generated by our branch network in the first quarter, which has allowed us to continue to reduce our borrowings from the Federal Home Loan Bank. Additionally, we have been diligent in reducing the overall cost of funds, resulting in an increase to our net interest margin as compared to the fourth quarter of 2009.

“On April 1^st Patrick J. Sullivan became President and CEO of Legacy Banks and President of Legacy Bancorp. We could not be more pleased about Pat coming on board. He is a person of high energy with a proven track record of over thirty years of experience building growth and profitability. He already has the management team focused on a profit improvement plan aimed

at margin expansion, expense reduction, expanding core commercial services while diversifying away from commercial real estate, and building household relationships through basic lending products.

“Earlier this month we were very proud to announce the agreement to acquire the Renaissance Investment Group, LLC, of Pittsfield, Massachusetts. This registered independent investment advisory company has enjoyed tremendous success since its inception in 2000. This transaction is a significant revenue opportunity as we leverage Renaissance with our existing wealth management programs and our overall customer base.

“Our capital to asset ratio, at 12.7%, continues to be very strong and is the foundation of a very strong balance sheet. While Legacy, and the industry in general, continue to face the current economic and financial challenges, we are more confident than ever in our financial strength, and our ability to grow and build shareholder value.”

The Company’s overall balance sheet remained relatively flat, decreasing by $41,000 from $946.3 million at December 31, 2009 to $946.2 million at March 31, 2010. Within the overall asset balances, the gross loan portfolio, excluding loans held for sale, decreased by $16.0 million, or 2.4% in the first quarter of 2010. Residential mortgages decreased $6.2 million, or 2.2% as the majority of the residential mortgage activity was in the 30 year fixed rate category, a product which the Bank currently sells in the secondary market with servicing retained. Commercial real estate loans decreased $9.0 million, or 3.4%, primarily due to loan payoffs and specific loan charge offs during the quarter. The available-for-sale investment portfolio increased by $12.8 million or 7.6%, while cash and cash equivalents decreased by $1.6 million, or 4.0% at March 31, 2010 as compared to year end.

Deposits have increased by $9.9 million, or 1.5%, to $661.2 million from a balance of $651.4 million at December 31, 2009. Deposits increased primarily in money market accounts and relationship savings which increased $8.4 million, or 13.3% and $13.4 million or 10.7%, respectively. These increases were partially offset by decreases in demand accounts and certificate of deposits (CD’s). Advances from the Federal Home Loan Bank of Boston (FHLBB) have decreased by $10.0 million, or 6.2% at March 31, 2010 as compared to the end of 2009 as the increase in overall deposits allowed the Bank to pay off high rate FHLBB borrowings as they matured during the quarter.

Overall stockholders’ equity decreased by $1.0 million, or 0.9% during the first quarter of 2010. Total equity was impacted by the net loss of $1.2 million, the declaration of a dividend of $0.05 per share during the first quarter and the purchase of 15,200 shares of stock at an average price of $9.56 per share as part of the Stock Repurchase Program announced in March 2009. These decreases to equity were partially offset by the amortization of unearned compensation and an increase in the unrealized gain on available-for-sale investment securities.

Overall nonperforming loans (NPLs) were $12.2 million at March 31, 2010, a decrease of $7.4 million as compared to the end of 2009. Part of this decrease was a result of the Bank charging off $5.4 million of loan balances, $3.8 million of which had been reserved for in previous quarters. These charge-offs also reduced the overall ratio of nonperforming assets to total assets to 1.47% at March 31, 2010 as compared to 2.20% at December 31, 2009. Legacy is, and always has been, diligent in evaluating its loan portfolio, especially given the current volatility in the

credit markets. The provision for loan losses was $2.4 million in the first quarter of 2010, an increase of $1.7 million as compared to the same period in 2009. This increase was the result of a continuous review and analysis of current market and economic conditions by management, as well as higher specific reserves established against certain loans in the first quarter of 2010. The charge-offs of NPLs also resulted in the reduction in the ratio of the allowance for loan losses to total loans to 1.25% at March 31, 2010, as compared to 1.67% at December 31, 2009 and 1.05% at March 31, 2009.

The Company’s net interest income decreased by $203,000, or 2.9% in the first quarter of 2010 as compared to the same period in 2009. The net interest margin (NIM) was 3.16% for the three months ended March 31, 2010, a decrease of 2 basis points from the first quarter of 2009, but an increase of 11 basis points from the fourth quarter of 2009 as the Bank has been diligent in lowering the costs of its average interest-bearing liabilities.

Non-interest income for the first quarter increased $1.3 million from the same period of 2009. The primary cause of the increase was the decrease in the amount of writedowns taken on investments deemed to be OTTI. The Bank incurred $299,000 of OTTI charges on certain limited partnership investments in 2010 as compared to OTTI charges of $1.6 million on certain bonds, equity securities and limited partnership investments in the first quarter of 2009. The Bank also had increases in fees from customers, portfolio management fees and gains on sale of investments, partially offset by a decrease on the gain on sale of mortgages.

Operating expenses increased by $96,000, or 1.4% for the first quarter of 2010 as compared to the same period of 2009. The bank had small increases in salaries and benefits, data processing, professional fees and FDIC insurance expense, offset by decreases in occupancy and advertising expense. The Company’s core efficiency ratio (reported efficiency ratio net of effect of non-core adjustments) for the quarter increased to 87.4% as compared to 83.6% in the first quarter of 2009 due to the decrease in net interest income and increase in operating expenses.

Reconciliation of Non-GAAP Financial Measures

This press release contains financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The Company’s management uses these non-GAAP measures in its analysis of the Company’s performance. These measures typically adjust GAAP performance measures to exclude significant gains or losses that are expected to be non-recurring and to exclude the effects of amortization of intangible assets (in the case of the efficiency ratio). Because these items and their impact on the Company’s performance are difficult to predict, management believes that presentations of financial measures excluding the impact of these items provide useful supplemental information that is essential to a proper understanding of the operating results of the Company’s core businesses. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.
