Forward-looking statements are based on, among other things, management’s beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy and SouthState.

South State cautions readers that forward-looking statements are subject to certain risks, uncertainties and assumptions that are difficult to predict with regard to, among other things, timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks, uncertainties and assumptions, include, among others, the following: (1) economic downturn risk, potentially resulting in deterioration in the credit markets, greater than expected noninterest expenses, excessive loan losses and other negative consequences, which risks could be exacerbated by potential continued negative economic developments resulting from the Covid19 pandemic, or from federal spending cuts and/or one or more federal budget-related impasses or actions; (2) interest rate risk primarily resulting from the low interest rate environment and historically low yield curve primarily due to government programs in place under the CARES Act and otherwise in response to the Covid19 pandemic, and their impact on the Bank’s earnings, including from the correspondent and mortgage divisions, housing demand, the market value of the bank’s loan and securities portfolios, and the market value of SouthState’s equity; (3) risks related to the merger and integration of SouthState and CSFL including, among others, (i) the risk that the cost savings and any revenue synergies from the merger may not be fully realized or may take longer than anticipated to be realized, (ii) the risk that the integration of each party’s operations will be materially delayed or will be more costly or difficult than expected or that the parties are otherwise unable to successfully integrate each party’s businesses into the other’s businesses, (iii) the amount of the costs, fees, expenses and charges related to the merger, (iv) reputational risk and the reaction of each company's customers, suppliers, employees or other business partners to the merger, (4) risks relating to the continued impact of the Covid19 pandemic on the company, including possible impact to the company and its employees from contacting Covid19, and to efficiencies and the control environment due to the continued work from home environment and to our results of operations due to government stimulus and other interventions to blunt the impact of the pandemic; (5) the impact of increasing digitization of the banking industry and movement of customers to on-line platforms, and the possible impact on the Bank’s results of operations, customer base, expenses, suppliers and operations, (6) controls and procedures risk, including the potential failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures; (7) potential deterioration in real estate values; (8) the impact of competition with other financial institutions, including pricing pressures (including those resulting from the CARES Act) and the resulting impact, including as a result of compression to net interest margin, (9) risks relating to the ability to retain our culture and attract and retain qualified people; (10) credit risks associated with an obligor’s failure to meet the terms of any contract with the bank or otherwise fail to perform as agreed under the terms of any loan-related document; (11) risks related to the ability of the company to pursue its strategic plans which depend upon certain growth goals in our lines of business; (12) liquidity risk affecting the Bank’s ability to meet its obligations when they come due; (13) risks associated with an anticipated increase in SouthState’s investment securities portfolio, including risks associated with acquiring and holding investment securities or potentially determining that the amount of investment securities SouthState desires to acquire are not available on terms acceptable to SouthState; (14) price risk focusing on changes in market factors that may affect the value of traded instruments in “mark-to-market” portfolios; (15) transaction risk arising from problems with service or product delivery; (16) compliance risk involving risk to earnings or capital resulting from violations of or nonconformance with laws, rules, regulations, prescribed practices, or ethical standards; (17) regulatory change risk resulting from new laws, rules, regulations, accounting principles, proscribed practices or ethical standards, including, without limitation, the possibility that regulatory agencies may require higher levels of capital above the current regulatory-mandated minimums and including the impact of the CARES Act, the Consumer Financial Protection Bureau regulations, and the possibility of changes in accounting standards, policies, principles and practices, including changes in accounting principles relating to loan loss recognition (CECL); (18) strategic risk resulting from adverse business decisions or improper implementation of business decisions; (19) reputation risk that adversely affects earnings or capital arising from negative public opinion; (20) cybersecurity risk related to the dependence of SouthState on internal computer systems and the technology of outside service providers, as well as the potential impacts of internal or external security breaches, which may subject the company to potential business disruptions or financial losses resulting from deliberate attacks or unintentional events; (21) reputational and operational risks associated with environment, social and governance matters; (22) greater than expected noninterest expenses; (23) excessive loan losses; (24) potential deposit attrition, higher than expected costs, customer loss and business disruption associated with the CSFL integration, and potential difficulties in maintaining relationships with key personnel; (25 the risks of fluctuations in market prices for SouthState common stock that may or may not reflect economic condition or performance of SouthState; (26) the payment of dividends on SouthState common stock, which is subject to legal and regulatory limitations as well as the discretion of the board of directors of SouthState, SouthState’s performance and other factors; (27) ownership dilution risk associated with potential acquisitions in which South State’s stock may be issued as consideration for an acquired company; (28) operational, technological, cultural, regulatory, legal, credit and other risks associated with the exploration, consummation and integration of potential future acquisition, whether involving stock or cash consideration; (29) major catastrophes such as hurricanes, tornados, earthquakes, floods or other natural or human disasters, including infectious disease outbreaks, including the ongoing COVID-19 pandemic, and the related disruption to local, regional and global economic activity and financial markets, and the impact that any of the foregoing may have on SouthState and its customers and other constituencies; (30) terrorist activities risk that results in loss of consumer confidence and economic disruptions; and (31) other factors that may affect future results of SouthState, as disclosed in SouthState’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, filed by SouthState with the U.S. Securities and Exchange Commission (“SEC”) and available on the SEC’s website at http://www.sec.gov, any of which could cause actual results to differ materially from future results expressed, implied or otherwise anticipated by such forward-looking statements.
