Legal Disclosures Forward-Looking Statements (p. 1 of 2) We have made forward-looking statements in this document, and in documents that we incorporate by reference, that are subject to risks and uncertainties. Forward-looking statements include information concerning possible or assumed future results of operations of the Company, the Bank, First Citizens Insurance or the Company on a consolidated basis. When we use words such as “believes,” “expects,” “anticipates,” or similar expressions, we are making forward-looking statements. Forward-looking statements may prove inaccurate. For a variety of reasons, actual results could differ materially from those contained in or implied by forward-looking statements: •Interest rates could change more rapidly or more significantly than we expect. •The economy could change significantly in an unexpected way, which would cause the demand for new loans and the ability of borrowers to repay outstanding loans to change in ways that our models do not anticipate. •The financial markets could suffer a significant disruption, which may have a negative effect on our financial condition and that of our borrowers, and on our ability to raise money by issuing new securities. •It could take us longer than we anticipate implementing strategic initiatives, including expansions, designed to increase revenues or manage expenses, or we may be unable to implement those initiatives at all. •Acquisitions and dispositions of assets and companies could affect us in ways that management has not anticipated. •We may become subject to new legal obligations or the resolution of litigation may have a negative effect on our financial condition or operating results. •We may become subject to new and unanticipated accounting, tax, regulatory or compliance practices or requirements. Failure to comply with any one or more of these requirements could have an adverse effect on our operations. •We could experience greater loan delinquencies than anticipated, adversely affecting our earnings and financial condition. •We could experience greater losses than expected due to the ever increasing volume of information theft and fraudulent scams impacting our customers and the banking industry. •We could lose the services of some or all of our key personnel, which would negatively impact our business because of their business development skills, financial expertise, lending experience, technical expertise and market area knowledge.

Legal Disclosures Forward-Looking Statements (p. 2 of 2) •The agricultural economy is subject to extreme swings in both the costs of resources and the prices received from the sale of products as a result of weather, government regulations, international trade agreements and consumer tastes, which could negatively impact certain of our customers. •Loan concentrations in certain industries could negatively impact our results, if financial results or economic conditions deteriorate. •Companies providing support services related to the exploration and drilling of the natural gas reserves in our market area may be affected by federal, state and local laws and regulations such as restrictions on production, permitting, changes in taxes and environmental protection, which could negatively impact our customers and, as a result, negatively impact our loan and deposit volume and loan quality. Additionally, the activities the companies providing support services related to the exploration and drilling of the natural gas reserves may be dependent on the market price of natural gas. As a result, decreases in the market price of natural gas could also negatively impact these companies, our customers. Additional factors are discussed in this Annual Report on Form 10-K under “Item 1A. Risk Factors.” These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. Forward-looking statements speak only as of the date they are made and the Company does not undertake to update forward-looking statements to reflect circumstances or events that occur after the date of the forward-looking statements or to reflect the occurrence of unanticipated events. Accordingly, past results and trends should not be used by investors to anticipate future results or trends.
