Alma, Michigan (FBMI) — Thomas R. Sullivan, President and Chief Executive Officer of Firstbank Corporation, announced earnings per share of $0.16 for the first quarter of 2009 compared to $0.29 in the first quarter of 2008. Net income was $1,513,000 for the quarter ended March 31, 2009, compared to $2,150,000 for the quarter ended March 31, 2008. Returns on average assets and average equity for the first quarter of 2009 were 0.46% and 4.8%, respectively. All per share amounts are fully diluted.

Total assets of Firstbank Corporation at March 31, 2009, were $1.415 billion, an increase of 2.3% over the year-ago period. Total portfolio loans of $1.135 billion were 0.6% above the level at March 31, 2008, but declined from December 31, 2008. Although mortgage refinance activity is very strong in Firstbank’s markets, this type of lending activity results in loans being financed in the secondary market rather than on the balance sheet of the company. While Firstbank has ample resources to increase loans on its balance sheet, demand for funding new ventures by quality borrowers remains weak due to uncertainty about the economy. Total deposits as of March 31, 2009, were $1.036 billion, compared to $1.012 billion at March 31, 2008, an increase of 2.4%.

Firstbank’s net interest margin, at 3.66% in the first quarter of 2009, decreased from 3.82% in the fourth quarter of 2008, and from 3.79% in the first quarter of 2008. The lower level of net interest margin was primarily a result of the full-quarter impact of the reduction in prime rate from 4.00% to 3.25% on December 16, 2008. Average earning assets increased 2.1% in the first quarter of 2009 compared to the fourth quarter of 2008 and 4.6% compared to the first quarter of 2008. Due to the higher level of earning assets, net interest income in the first quarter of 2009 was 1.2% above the year-ago period. However, the decrease in net interest margin caused net interest income in the first quarter of 2009 to fall 3.0% below the level in the fourth quarter of 2008. During the first quarter of 2009, the margin showed some improvement on a monthly basis as funding costs were reduced.

Earnings in the first quarter of 2009 were also affected by the level of provision for loan loss expense, which was determined by amounts necessary to keep the allowance for loan losses at the appropriate level. Provision expense in the first quarter of 2009 was $1,588,000, a decrease compared to the $2,947,000 of the fourth quarter of 2008, but higher than the $816,000 amount in the first quarter of 2008.

Gain on sale of mortgages continued very strong in the first quarter of 2009, generating nearly five times the revenue generated in the fourth quarter of 2008, and more than twice the revenue compared to a fairly strong first quarter of 2008. Sharp declines in mortgage interest rates in December of 2008 and continuing into the first quarter of 2009 are resulting in very strong mortgage refinance activity. Increased losses on sale of other real estate and reduced valuations in deferred compensation plan assets (which are matched by reduced other expenses) offset some of the revenue benefits from the mortgage business. As a result, total non-interest income was 9% above the year-ago quarter.

Firstbank continues to emphasize cost control during this period of earnings pressure. While the total of salaries and employee benefits increased 2% from the fourth quarter of 2008 to the first quarter of 2009, the increase was entirely a function of the timing of accruals for various employee benefits expenses and variable compensation. The sub-category of salaries and wages only, in the first quarter of 2009, was 3.1% below its level in both the fourth quarter of 2008 and the first quarter of 2008. Non-interest expenses other than salaries and employee benefits increased 15% in the first quarter of 2009 compared to the first quarter of 2008, with the increase driven mainly by factors related to problems in the economy and the financial system. FDIC insurance premiums increased 228% compared to the year-earlier period. Legal fees related to loans, write-downs of the value of other real estate, and expenses related to the management of other real estate also increased. Although non-interest expense other than salaries and employee benefits in the first quarter of 2009 were higher than the year-ago period, they were 2.7% lower than in the fourth quarter of 2008.

Mr. Sullivan stated, “The economic environment continues to be challenging for bank earnings. With interest rates at low levels, net interest margins are thin. Costs of collections and working with borrowers who are having difficulty are abnormally high, and outright loan losses are obviously above normal. In this environment, we have taken steps to ensure that the company remains financially strong. We have resources to expand lending when there is demand for new money by quality borrowers in our markets with good business or investment plans. We also work very hard to refinance existing loans for customers when there is an opportunity to improve their situation. Residential mortgage refinance activity was the strongest area of our business in the first quarter, and we also found opportunities to refinance good commercial projects where the original lenders need to reduce their commitments. We know that we, like all banks, will have to absorb a special assessment by the FDIC that will be expensed in the second or third quarter of this year. In our case, if the special assessment is reduced to the 10 basis point level that is being discussed, the cost will be approximately $1.1 million.

“Most importantly, we know that the core operations of our company are sound, that we have the strength to get through the challenging times, and that earnings will return to more normal levels when the economic ills are behind us. Our people continue to be loyal servants of their customers’ needs and are dedicated to the well-being of our company and our communities. Combined with our capital strength, this personnel strength will keep Firstbank Corporation and our affiliate banks positioned well for the future.”

At March 31, 2009, the ratio of the allowance for loan losses to loans was 1.24% compared to 1.26% at December 31, 2008, and increased from 1.02% at March 31, 2008. The ratio of allowance for loan loss to non-performing loans stood at 61% on March 31, 2009, compared to 59% at December 31, 2008.

Net charge-offs rose to $2,054,000 in the first quarter of 2009 and were 0.71% of average loans on an annualized basis. The ratio of non-performing loans (including loans past due over 90 days) to loans was 2.04% at March 31, 2009, compared to 2.14% as of December 31, 2008, and 1.27% at March 31, 2008.

Total equity increased 28.7% in the first quarter of 2009, reflecting the improvement obtained by the issuance of $33 million preferred stock at the end of January. The ratio of average equity to average assets rose to 9.4% in the first quarter of 2009 – about a full percentage point over levels of past years. All of Firstbank Corporation’s affiliate banks met the regulatory well-capitalized requirements prior to the issuance of preferred stock in January and continue to meet these requirements.
