Alma, Michigan (FBMI) — Thomas R. Sullivan, President and Chief Executive Officer of Firstbank Corporation, announced earnings per share of $0.10 for the third quarter of 2009, the same as the $0.10 earned in the third quarter of 2008. Net income available to common shareholders was $804,000 compared to $737,000 in the year-ago third quarter, and net income increased to $1,217,000 compared to $737,000. Net income was $2,792,000 for the first nine months of 2009, compared to $3,179,000 for the first nine months of 2008. Returns on average assets and average equity for the third quarter of 2009 were 0.33% and 3.2%, respectively, increasing from 0.21% and 2.5% respectively in the year-ago third quarter. All per share amounts are fully diluted.

Earnings continued to be impacted by elevated provisions for loan loss, and expense for FDIC insurance, greatly exceeding year-ago levels. The provision expense in the third quarter of 2009 was $2,821,000, down from the $5,276,000 expensed in the second quarter of 2009, but more than double the $1,082,000 expensed in the third quarter of 2008. For the first nine months of 2009, provision expense was $9,685,000, up from the $5,309,000 provided in the first nine months of 2008, exceeding net charge-offs of $7,486,000. Firstbank’s experience with loan charge-offs continues to be favorable compared to results in Michigan and other areas of the country.

Expense for FDIC deposit insurance was $448,000 in the third quarter of 2009, 170% over the $166,000 amount in the third quarter of 2008. Year-to-date in 2009, FDIC deposit insurance expense was $1,974,000, over five times the year-ago level of $382,000. The FDIC assessed a special charge in the second quarter to all banks to help with the costs of resolving bank failures across the country. The total amount of the special assessment to Firstbank was $642,000. There is currently a proposal for the FDIC to require all banks to pre-pay three years of FDIC premiums on December 31, 2009. For Firstbank this prepayment amount would be nearly $7 million and would be expensed over the next three years.

Firstbank improved its net interest margin to 3.95% in the third quarter of 2009 from 3.77% in the second quarter of 2009, and the 3.82% in the third quarter of 2008. Strategies aimed at incorporating floors on variable rate loans and re-pricing deposits upon renewal at currently competitive rates, resulted in the improvement in margin. Firstbank’s banks have also been able to reduce their reliance on Federal Home Loan Bank advances and brokered deposits as core deposits have increased. This improvement in margin helped net interest income in the first nine months of 2009 increase 3.4% compared to the first nine months of 2008.

Gain on sale of mortgage loans was $1,104,000 in the third quarter of 2009, declining 65% from the $3,109,000 in the second quarter of 2009 but representing an increase of nearly 250% over the level in the third quarter of 2008.

Promotional costs associated with mortgage production tailed off in the third quarter consistent with the decline in volume. Year over year, promotional costs related to mortgage production are up $377,000. Notwithstanding the increased expense, the higher level of mortgage production has been beneficial to earnings as the gain on sale of mortgages has increased over $4.5 million year to date. Other non-interest expenses continue to be impacted by the difficult credit cycle. Costs related to the maintenance and disposal of other real estate owned amounted to over $1,264,000 during the first nine months of 2009, an increase of $770,000 from the first nine months of 2008. Legal fees largely resulting from increased collection efforts and management of troubled credit situations were $553,000 in the first nine months of 2009, an increase of over $270,000 from the first nine months of 2008.

Expense control efforts in the more manageable categories were successful. Comparing the first nine months of 2009 with the first nine months of 2008, salaries and employee benefits expense increased only 0.7% and occupancy and equipment expense declined 8.7%. The category of other noninterest expense showed an increase from $8,508,000 in the first nine months of 2008 to $10,117,000 in the first nine months of 2009, but over 88% of the increase was related to legal and other costs of managing problem loans and costs associated with the very profitable surge in the mortgage business, leaving the remaining costs in the category of other noninterest expense to increase 2.5%.

Total assets of Firstbank Corporation at September 30, 2009, were $1.430 billion, an increase of 1.6% over the year-ago period. Total portfolio loans of $1.125 billion were 2.6% below the year-ago level. Commercial and commercial real estate loans increased 6.2% over this twelve month period, but residential mortgage, real estate construction, and consumer loans decreased. Although mortgage refinance activity has been 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 capital and funding 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 September 30, 2009, were $1.073 billion, compared to $1.028 billion at September 30, 2008, an increase of 4.4%.

Mr. Sullivan stated, “Our lenders continue to do an excellent job of working with borrowers who are financially stressed by the current economic conditions, to both protect the interests of the bank and our shareholders as well as structure credits in the best possible way to accommodate expected cash flows. While we have very little exposure to auto manufacturers and suppliers directly, we know that their problems will ripple through the economy. Considering all of the credit related costs, we were pleased to make a positive net income in the quarter amounting to a return on assets of 0.33%.

“Due to the low level of stock prices for the industry and the implications for the valuation of the assets of financial companies, and according to accounting guidance, we commissioned a third-party-expert valuation of goodwill on our balance sheet during the third quarter, to test for impairment. We were pleased to find that the proper application of accounting rules and principles indicates that the amount of goodwill on our books is not considered impaired and requires no charge to earnings. As a result, we continue to show a book value per share ($15.11 at September 30, 2009) which is substantially above tangible book value per share ($10.09).

“We are very disappointed in the low level of stock prices in the industry –substantially below book values – as are all of our shareholders; however, with the good people employed by our company doing the right things for both our customers and our shareholders and the continuing strong financial condition of our company and our banks, we believe we are well positioned to emerge from the recession in a strong competitive position and with excellent opportunity for earnings growth when the time arrives.”

At September 30, 2009, the ratio of the allowance for loan losses to loans increased to 1.49%, compared to 1.48% at June 30, 2009, 1.26% at December 31, 2008, and 1.11% at September 30, 2008. The ratio of allowance for loan loss to non-performing loans stood at 56% on September 30, 2009, compared to 59% at December 31, 2008.

Net charge-offs were $2,696,000 in the third quarter of 2009 after having risen to $2,736,000 in the second quarter and $2,054,000 in the first quarter. For the nine months of 2009, net charge-offs were $7,486,000, representing 0.88% of average loans on an annualized basis. This level of charge-offs continues to compare favorably in the industry. The ratio of non-performing loans (including loans past due over 90 days) to loans was 2.69% at September 30, 2009, compared to 2.14% as of December 31, 2008, and 1.81% at September 30, 2008.

Total equity increased 0.8% during the third quarter of 2009 and was 29.7% above the level at December 31, 2008, 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 was 10.3% in the third quarter of 2009, approximately two full percentage points over the year-ago level. 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.
