Forward-Looking Statements This presentation contains estimates, predictions, opinions, projections and other “forward-looking statements” as that phrase is defined in the Private Securities Litigation Reform Act of 1995. Such statements include, without limitation, statements relating to the impact Southern States and CBB Bancorp expect the Merger to have on the combined entities operations, financial condition, and financial results, and Southern States’ expectations about its ability to successfully integrate the combined businesses and the amount of cost savings and other benefits Southern States expects to realize as a result of the Merger. Forward-looking statements also include, without limitation, predictions or expectations of future business or financial performance as well as its goals and objectives for future operations, financial and business trends, business prospects, and management’s outlook or expectations for earnings, revenues, expenses, capital levels, liquidity levels, asset quality or other future financial or business performance, strategies or expectations, and are subject to risks and uncertainties. These statements often, but not always, are preceded by, are followed by or otherwise include the words such as “may,” “can,” “should,” “could,” “to be,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “likely,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “target,” “project,” “would” and “outlook,” or the negative version of those words or other similar words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about the banking industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. This may be especially true given recent events and trends in the banking industry and interest rate volatility. Although Southern States and CBB Bancorp believe that the expectations reflected in such forward-looking statements are reasonable as of the dates made, they cannot give any assurance that such expectations will prove correct and actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. Such risks and uncertainties include, but are not limited to, the possibility that the proposed Merger does not close when expected or at all because required regulatory, shareholder or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all; the delay in or failure to close for any other reason; the outcome of any legal proceedings that may be instituted against Southern States or CBB Bancorp; the occurrence of any event, change or other circumstance that could give rise to the right of one or both parties to terminate the Agreement; the risk that the businesses of Southern States and CBB Bancorp will not be integrated successfully; the possibility that the cost savings and any synergies or other anticipated benefits from the proposed Merger may not be fully realized or may take longer to realize than expected; disruption from the proposed Merger making it more difficult to maintain relationships with employees, customers or other parties with whom Southern States or CBB Bancorp have business relationships; diversion of management time on Merger-related issues; risks relating to the potential dilutive effect of the shares of Southern States common stock to be issued in the proposed Merger; the reaction to the proposed Merger of the companies’ customers, employees and counterparties; and other factors, many of which are beyond the control of Southern States and CBB Bancorp. For additional information, refer to the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Southern States’ Annual Report on Form 10-K for the year ended December 31, 2022 and any updates to those risk factors set forth in Southern States’ Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings, which have been filed by Southern States with the SEC and are available on the SEC’s website at www.sec.gov.
