FORWARD-LOOKING STATEMENTS
Certain statements in this news release contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, such as statements relating to the completion, timing and expected size of the offering, the anticipated closing date of the offering, the anticipated use of proceeds from the offering, future plans and expectations, and are thus prospective. Such forward-looking statements are identified by words such as “believe,” “expect,” “anticipate,” “estimate,” “preliminary”, “intend,” “plan,” “target,” “continue,” “lasting,” and “project,” as well as similar expressions. Such statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. Although we believe that the assumptions underlying the forward-looking statements are reasonable, any of the assumptions could prove to be inaccurate. Therefore, we can give no assurance that the results contemplated in the forward-looking statements will be realized. The inclusion of forward-looking information should not be construed as a representation by the Company or any other person that the future events, plans or expectations described herein will be achieved.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: (1) competitive pressures among depository and other financial institutions may increase significantly and have an effect on pricing, spending, third-party relationships and revenues; (2) the strength of the United States economy in general and the strength of the local economies in which the Company conducts operations may be different than expected; (3) the rate of delinquencies and amounts of charge-offs, the level of allowance for credit loss, the rates of loan and deposit growth as well as pricing of each product, or adverse changes in asset quality in our loan portfolio, which may result in increased credit risk-related losses and expenses; (4) changes in legislation, regulation, policies or administrative practices, whether by judicial, governmental or legislative action, including, but not limited to, changes affecting oversight of the financial services industry or consumer protection, the regulatory landscape or capital market; (5) adverse conditions in the stock market, the public debt market and other capital markets (including changes in interest rate conditions) could continue to have a negative impact on the Company, including the timing, size, pricing or completion of the offering; (6) changes in interest rates, which may continue to affect the Company’s net income, interest expense, prepayment penalty income, mortgage banking income, and other future cash flows, or the market value of the Company’s assets, including its investment securities; (7) trade wars, government shutdowns, or a potential recession which may cause adverse risk to the overall economy, and could indirectly pose challenges to our clients and to our business; (8) any increase in FDIC assessments which have increased and may continue to increase our cost of doing business; and (9) changes in accounting principles, policies, practices, or guidelines. Additional factors that could cause our results to differ materially from those described in the forward-looking statements can be found in our reports (such as Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) filed with the SEC and available at the SEC’s Internet site (www.sec.gov). All subsequent written and oral forward-looking statements concerning the Company or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements above. We do not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made, except as required by law.
