Forward-looking Statements

This presentation contains forward-looking statements that describe our future plans, strategies and expectations. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate” or words of similar meaning, or future or conditional verbs such as “will,” “would,” “should,” “could” or “may.” All forward-looking statements are based on assumptions and involve risks and uncertainties, many of which are beyond our control and which may cause our actual results, performance or achievements to differ materially from the results, performance or achievements contemplated by the forward-looking statements. These risks and uncertainties include, among other things:

Continued weakness in economic and business conditions, nationally and in our market areas, which could increase credit- related losses and expenses and/or limit growth.

Further declines in the market value of investment securities that are considered to be other-than-temporary, which would negatively impact our earnings and capital levels.

Increases in defaults by borrowers and other delinquencies could result in increases in our provision for credit losses and related expenses.

Changes in legislative or regulatory requirements applicable to us and our subsidiaries could increase costs, limit certain operations and adversely affect results of operations.

Fluctuations in interest rates and market prices could reduce our net interest margin and asset valuations and increase our expenses.

Reduced wholesale funding capacity or higher borrowing costs due to capital constraints at the Federal Home Loan Bank, which would reduce our liquidity and negatively impact earnings and net interest margin.

Competitive pressures among depository and other financial institutions nationally and in our market areas may increase significantly.

Our inability to manage growth effectively, including the successful expansion of our customer support, administrative infrastructure and internal management systems, could adversely affect our results of operations and prospects.

The inability to successfully execute our strategic growth initiatives, which could limit further revenue and earnings growth.

Changes in tax requirements, including tax rate changes, new tax laws and revised tax law interpretations may increase our tax expense or adversely affect our customers’ businesses.

The consequences of continued bank acquisitions and mergers in our market areas, resulting in fewer but much larger and financially stronger competitors, could increase competition for financial services to our detriment.

Other risks and uncertainties described in this presentation and the other reports that First Commonwealth files with the Securities and Exchange Commission, including its most recent Annual Report on Form 10-K.

In light of these risks, uncertainties and assumptions, you should not place undue reliance on any forward-looking statements in this presentation. We undertake no obligation to publicly update or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise.
