FIRST COMMONWEALTH ANNOUNCES 2009 FOURTH QUARTER AND FULL-YEAR FINANCIAL RESULTS

Key Highlights Include Net Income and Continued Core Business Growth

Indiana, PA., January 28, 2010—First Commonwealth Financial Corporation (NYSE: FCF), the holding company for First Commonwealth Bank, announced today financial results for the year and fourth quarter ended December 31, 2009.

Fourth Quarter Results

First Commonwealth reported net income for the fourth quarter 2009 of $3.3 million, or $0.04 per diluted share, compared to net income of $8.9 million, or $0.11 per diluted share, in the fourth quarter of 2008. The year-over-year decline was primarily the result of a $10.4 million ($6.8 million after tax) increase in the provision for credit losses as well as an increase of $943 thousand ($613 thousand after tax) in other-than-temporary impairment charges. The higher provision was primarily related to a commercial and industrial (C&I) loan in Western Pennsylvania that migrated to nonaccrual status during the fourth quarter of 2009. The other-than-temporary impairment charges resulted from further credit deterioration of the company’s pooled trust preferred collateralized debt obligations. Sequentially, net income improved from the loss of $5.9 million reported in the third quarter 2009.

“Although our fourth quarter remained challenging, we’re pleased to report net interest income growth that was fueled by a rise in low-cost transaction and savings deposits. We’re focused on growing our core business and that’s helping to drive improved results,” said John J. Dolan, President and CEO. “While our provision for credit losses remains high, our fourth quarter provision of $21.1 million was down from the previous quarter. Additionally, we continue to be disciplined in providing for credit loss provisions as economic conditions affecting the credit quality of our loan portfolio have not subsided. We believe these actions are prudent during this distressed economic period. At the same time, our capital ratios are strong, allowing us to work through this difficult environment.”

Developments during the fourth quarter included:

Other developments:

Average diluted shares in the fourth quarter 2009 were 5.6% greater than the comparable quarter in 2008 primarily due to the issuance of 11.5 million shares of common stock in connection with a capital raise completed on November 5, 2008.

First Commonwealth’s Total, Tier 1 and leverage capital ratios were 11.5%, 10.3% and 9.2%, respectively, at December 31, 2009. First Commonwealth Financial Corporation declared a dividend of $0.03 per share payable on February 12, 2010, to shareholders of record at the close of business January 29, 2010.

Net Interest Income and Margin

2009 fourth-quarter net interest income increased $784 thousand, or 1.5%, from the fourth quarter of 2008. The increase was a result of growth in earning assets, partially offset by a decline in the net interest margin.

The 2009 fourth-quarter net interest margin decreased nine basis points to 3.78%, compared with 3.87% in the corresponding prior-year period. The decrease in net interest margin can be attributed to declines in yields on total interest-earning assets exceeding the cost of interest-bearing liabilities. In the fourth quarter of 2008, the net interest margin enjoyed the benefit of abnormally high LIBOR rates which resulted in a higher net interest margin. The decrease in the cost of interest-bearing liabilities resulted from lower interest rates, combined with a shift in the mix of liabilities to low-cost transaction and savings deposits and short-term borrowings from time deposits and long-term debt.

Average interest-earning assets increased by $187.4 million, or 3.3%, in the fourth quarter of 2009 compared to the fourth quarter of 2008, driven by an increase in average loans of $352.1 million, or 8.2%, due primarily from the loan growth First Commonwealth experienced in the fourth quarter of 2008. This year-over-year gain was funded by investment run-off and deposit growth. Average investment securities decreased $164.9 million and average deposits increased $263.1 million from fourth quarter 2008 to fourth quarter 2009.

The mix of deposits continued to improve during the fourth quarter of 2009. Average time deposits decreased $223.7 million, or 12.0%, from the fourth quarter of 2008 to the fourth quarter of 2009. This run-off was offset with increased levels of lower costing transaction and savings deposits. Average noninterest-bearing demand deposits increased $44.8 million, or 7.9%, and average interest-bearing demand deposits and savings deposits increased $441.9 million, or 23.6%, from the fourth quarter of 2008 to the fourth quarter of 2009.

Non-Interest Income

Non-interest income decreased $281 thousand, or 2.8%, in the 2009 fourth quarter compared to the same period last year, primarily due to higher credit related other-than-temporary impairment losses of $943 thousand.

Insurance and retail brokerage commissions rose $583 thousand, or 47.2%, as additional producers and an enhanced calling program yielded higher sales. Card-related interchange income increased $345 thousand due to growth in usage of debit cards and larger dollar transactions. These improvements were partially offset by a decline of $600 thousand in other operating income primarily as a result of the decrease in swap fee income.

“In 2010 we will better integrate First Commonwealth’s wealth management capabilities within the commercial and retail side of the Bank,” Mr. Dolan commented.

Non-Interest Expense

Non-interest expense decreased $1.4 million, or 3.2%, for the fourth quarter of 2009 from the fourth quarter of 2008 due to lower other operating expenses and salaries. Other operating expenses decreased $2.6 million primarily due to a $1.2 million low income housing partnership impairment charge recorded in the fourth quarter of 2008 which was recorded to write down the value of underlying real estate. The remaining $1.4 million decrease in other operating expenses was due to declines in various expense accounts as a result of First Commonwealth’s cost containment efforts. Salaries decreased $932 thousand due to lower staff levels and incentive pay. The decrease in other operating expenses and salaries were primarily offset by the increases of $1.9 million in FDIC insurance, $450 thousand in hospitalization costs and $330 thousand in collection and repossession expenses.

Credit Quality and Provision for Credit Losses

For the quarter ending December 31, 2009, nonperforming loans increased $14.7 million to $148.6 million from September 30, 2009. This was primarily due to a $46.3 million C&I loan in Pennsylvania that migrated to nonaccrual status during the fourth quarter. The borrower is an individual who has had a loan relationship with the Bank since 2004 and whose business is retail property management and development.

Net charge-offs were $29.9 million in the 2009 fourth quarter, compared to $3.4 million in the prior-year period. Nearly 90 percent of the fourth quarter 2009 charge-offs were nonaccrual loans. Nonperforming loans as a percentage of total loans increased from 2.88% at September 30, 2009 to 3.20% at December 31, 2009.

Loans past due in excess of 90 days and still accruing at December 31, 2009, increased $785 thousand to $15.2 million compared to September 30, 2009. The majority of these loans are consumer loans secured by residential real estate.

The 2009 fourth quarter provision for credit losses was $21.1 million, an increase of $10.4 million compared to the fourth quarter of 2008. The allowance for credit losses as a percentage of end-of-period loans decreased from 1.95% at September 30, 2009 to 1.76% at December 31, 2009 as net charge-offs of $29.9 million exceeded the provision for credit losses for the fourth quarter of 2009. The fourth quarter 2009 charge-offs were primarily nonperforming loans in which an allowance was established in prior quarters.

Income Tax

The provision for income taxes for the 2009 fourth quarter decreased $3.0 million from the year-ago period primarily due to the decrease in income before taxes, partly offset by a decline in nontaxable income and tax credits. First Commonwealth’s effective tax rate was 107.0% for the tax benefit in the 2009 fourth quarter, compared to 12.4% for the tax expense in the comparable 2008 quarter. The effective tax rate in the 2009 fourth quarter reflects permanent differences and tax credits. Non-taxable income and tax credits had a greater impact on the effective tax rate during the 2009 fourth quarter due to the lower pretax income, compared to the pretax income in the fourth quarter 2008.

Single Issue Trust Preferred Securities, Subordinated Debentures and Pooled Trust Preferred Collateralized Debt Obligations

First Commonwealth’s investment portfolio includes single issue trust preferred securities, subordinated debentures and pooled trust preferred collateralized debt obligations.

As of December 31, 2009, our single issue portfolio consists of 16 issues with a book value of $21.4 million and an estimated fair value of $17.6 million, while the book value and estimated fair value of the three subordinated debentures totaled $1.2 million. The single issues and subordinated debentures are issued primarily from money center and large regional banks.

The company’s pooled trust preferred collateralized debt obligations consist of 14 securities comprised of 376 banks and other financial institutions. Two pooled securities are senior tranches and the remainder are mezzanine tranches. As of December 31, 2009, the book value of our pooled securities totaled $70.2 million with an estimated fair value of $30.2 million. In the fourth quarter of 2009, a $4.8 million other-than-temporary impairment charge was recorded on eleven trust preferred collateralized debt obligations that are expected to experience a principal shortfall. The amount of impairment charge recognized represents the expected credit loss on these securities.

Based on management’s valuation analysis as of December 31, 2009, all of the single issues and subordinated debentures and the remainder of the pooled trust preferred collateralized debt obligations are expected to return 100% of their principal and interest. However, additional bank failures or interest deferrals and defaults occurring before the filing of First Commonwealth’s 10-K may require additional other-than-temporary impairment charges for the fourth quarter of 2009.

2010 Growth Strategy

“In 2010, we intend to grow First Commonwealth and improve our financial performance by continuing to seize the opportunity from market disruptions within our footprint, primarily in the Pittsburgh market,” Mr. Dolan said. “We will continue to focus on transaction and savings deposit growth, with a focus on the small business segment and reduce short-term borrowing dependency. We will also continue to reduce the size of our individual credit exposure to be more in line with current policies.”

Year-to-Date Results

Net loss for the year ended December 31, 2009 was $19.5 million, or $0.23 per share compared to net income of $43.1 million, or $0.58 per diluted share in the same period last year. The decrease was due to the $77.5 million ($50.4 million after tax) increase in the provision for credit losses and a $22.3 million ($14.5 million after tax) increase in other-than-temporary impairment losses related primarily to our pooled trust preferred collateralized debt obligations.

Net Interest Income and Margin

Net interest income for the year ended December 31, 2009, increased $17.9 million, or 9.5%, from 2008 despite the negative impact of loans transferred to nonaccrual status. The increase was a result of both growth in earning assets and an increase in the net interest margin.

The net interest margin for 2009 increased 14 basis points to 3.71% compared with 3.57% in 2008. The increase in net interest margin is attributable to increased loan volume and decreases in the cost of interest-bearing liabilities exceeding the declines in yields on total interest-earning assets. The decrease in the cost of interest-bearing liabilities is the result of lower interest rates, combined with a shift in the mix of liabilities to low-cost transaction and savings deposits and short-term borrowings from time deposits and long-term debt.

In 2009, average time deposits declined $263.5 million, or 13.2%, offset with increases in lower-costing transaction and savings accounts. Average non-interest-bearing demand deposits increased $45.8 million, or 8.4%, and average interest-bearing demand deposits and savings deposits increased $350.6 million, or 19.8%. The net interest margin for the year ended December 31, 2009 was negatively impacted $2.5 million, or four basis points (0.04%) due to reversal of previously recorded income on loans transferred to nonaccrual status during 2009 compared to $667 thousand, or one basis point (0.01%) in 2008.

5

Average interest-earning assets in 2009 were $252.7 million, or 4.5%, higher in 2009 versus 2008, primarily from an increase in average loans of $472.7 million, or 11.6%. The increase in loans was funded by investment run-off, and deposit and short-term borrowings growth. Average investment securities declined $220.2 million while average deposits increased $132.9 million and average short-term borrowings increased by $261.9 million.

Non-Interest Income

Non-interest income in 2009 decreased $22.6 million from 2008. The decline was primarily due to increased credit-related other-than-temporary impairment losses of $23.8 million on pooled trust preferred collateralized debt obligations in addition to the $1.2 million decline in net securities gains. These were partially offset by the decrease of $1.5 million in other-than-temporary impairment losses on bank equity securities in 2009 compared to 2008.

Insurance and retail brokerage commissions increased $2.0 million as a result of higher sales due to additional producers and an enhanced calling program. Other operating income increased $1.0 million due to a $2.1 million gain on a favorable legal settlement. Card related interchange income increased by $950 thousand primarily due to growth in debit card use and larger dollar transactions. These increases were partially offset by decreases in service charges on deposit accounts of $1.1 million, income from bank owned life insurance of $1.1 million and trust income of $834 thousand. The decline in service charges on deposit accounts was due to lower overdraft activity. Income from bank owned life insurance decreased due to lower crediting rates and trust income decreased as a result of lower market values of assets under management.

During the first quarter of 2009, First Commonwealth early adopted FASB Accounting Standards Codification 320-10-65, Transition Related to FSP FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-than-Temporary Impairments, which requires that credit related other-than-temporary impairment be recognized in earnings while noncredit-related other-than-temporary impairment on securities not expected to be sold be recognized in other comprehensive income (“OCI”).

In accordance with the new accounting guidance, the noncredit-related portion of other-than-temporary impairment losses previously recognized in earnings during 2008 was reclassified as a cumulative effect adjustment that increased retained earnings and decreased accumulated OCI. Of the $13.0 million in other-than-temporary impairment charges recognized in 2008, $6.5 million related to noncredit-related impairment. Therefore, the cumulative effect adjustment to retained earnings totaled $6.5 million, or $4.2 million, net of tax.

Non-Interest Expense

Non-interest expense for the year ended December 31, 2009, increased $12.5 million, or 7.9%, from the corresponding period in 2008 primarily due to higher FDIC insurance costs, salaries and employee benefits and collection and repossession expense.

Provision for Credit Losses

The provision for credit loss for the year ended December 31, 2009, increased $77.5 million from the comparable period in 2008 due primarily to the deterioration in current economic conditions surrounding industries closely linked to the residential housing, hospitality, and

recreation markets outside of Pennsylvania, as well as deterioration in commercial loans in and outside of our local market. For the year ended December 31, 2009, the provision of $100.6 million exceeded the net charge-offs of $71.7 million. Please refer to the Credit Quality and Provision for Credit Losses section above for further detail.

Income Tax

The 2009 provision for income taxes decreased $32.2 million from 2008 due to the $94.7 million decline in income before taxes. The effective tax rate was 56.7% for the tax benefit in the year ended December 31, 2009, compared to 13.3% for the tax expense in 2008. Nontaxable income and tax credits had a greater impact on the effective tax rate for the year ended December 31, 2009, due to the 2009 pretax loss compared to pretax income for the year ended December 31, 2008.
