WINTER HAVEN, FL – October 26, 2023 – SouthState Corporation (NASDAQ: SSB) today released its unaudited results of operations and other financial information for the three-month and nine-month periods ended September 30, 2023.

“Despite the challenges of the economic backdrop and yield curve, SouthState delivered another quarter of steady, mid-single digit growth in loans and customer deposits", said John C. Corbett, SouthState’s Chief Executive Officer. "Our granular and relationship-based deposit funding continues to act as a ballast for our franchise. While we remain mindful of the lag effects of the rapid rise in interest rates on the broader economy, we are confident in our underwriting discipline and the benefits of being located in many of the fastest growing markets in the country."

Highlights of the third quarter of 2023 include:

Returns

● Reported Diluted Earnings per Share (“EPS”) of $1.62; Adjusted Diluted EPS (Non-GAAP) of $1.62

● Net Income of $124.1 million; Adjusted Net Income (Non-GAAP) of $124.3 million

● Return on Average Common Equity of 9.2%; Return on Average Tangible Common Equity (Non-GAAP) and Adjusted Return on Average Tangible Common Equity (Non-GAAP) of 15.5%*

● Pre-Provision Net Revenue (“PPNR”) per weighted average diluted share (Non-GAAP) of $2.48

● Net charge-offs of $13.2 million, or 0.16% annualized; $32.7 million Provision for Credit Losses (“PCL”), including release for unfunded commitments; 3 basis points build in total allowance for credit losses (“ACL”) plus reserve for unfunded commitments to 1.59%; Year-to-date net charge-offs of $17.5 million, or 0.08% annualized

● Noninterest Income of $73 million, down $4 million compared to the prior quarter, primarily due to a decrease in correspondent banking and capital markets income; Noninterest Income represented 0.64% of average assets for the third quarter of 2023

Footnotes to tables:

(1) Includes loan accretion (interest) income related to the discount on acquired loans of $4.1 million, $5.5 million, $7.4 million, $7.3 million, and $9.6 million during the quarters ended September 30, 2023, June 30, 2023, March 31, 2023, December 31, 2022, and September 30, 2022, respectively.

(2) Adjusted earnings, adjusted return on average assets, adjusted EPS, and adjusted return on average equity are non-GAAP measures and exclude the gains or losses on sales of securities, merger, branch consolidation and severance related expense, and initial PCL on nonPCD loans and unfunded commitments from acquisitions.  Management believes that non-GAAP adjusted measures provide additional useful information that allows readers to evaluate the ongoing performance of the Company.  Non-GAAP measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider the Company's performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company.  Non-GAAP measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the Company's results or financial condition as reported under GAAP.  Adjusted earnings and the related adjusted return measures (non-GAAP) exclude the following from net income (GAAP) on an after-tax basis: (a) pre-tax merger, branch consolidation and severance related expense of $164,000, $1.8 million, $9.4 million, $1.5 million, and $13.7 million for the quarters ended September 30, 2023, June 30, 2023, March 31, 2023, December 31, 2022, and September 30, 2022, respectively; (b) net securities gains of $45,000 and $30,000 for the quarters ended March 31, 2023 and September 30, 2022, respectively.

(3) The tangible measures are non-GAAP measures and exclude the effect of period end or average balance of intangible assets.  The tangible returns on equity and common equity measures also add back the after-tax amortization of intangibles to GAAP basis net income.  Management believes that these non-GAAP tangible measures provide additional useful information, particularly since these measures are widely used by industry analysts for companies with prior merger and acquisition activities.  Non-GAAP measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider the Company's performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company.  Non-GAAP measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the Company's results or financial condition as reported under GAAP. The sections titled "Reconciliation of Non-GAAP to GAAP" provide tables that reconcile non-GAAP measures to GAAP.

(4) Adjusted efficiency ratio is calculated by taking the noninterest expense excluding merger, branch consolidation and severance related expense and amortization of intangible assets, divided by net interest income and noninterest income excluding securities gains (losses). The pre-tax amortization expenses of intangible assets were $6.6 million, $7.0 million, $7.3 million, $8.0 million, and $7.8 million for the quarters ended September 30, 2023, June 30, 2023, March 31, 2023, December 31, 2022, and September 30, 2022, respectively.

(5) The dividend payout ratio is calculated by dividing total dividends paid during the period by the total net income for the same period.

(6) September 30, 2023 ratios are estimated and may be subject to change pending the final filing of the FR Y-9C; all other periods are presented as filed.

(7) Loan data excludes mortgage loans held for sale.

(8) During the fourth quarter of 2022, the Company determined the variation margin payments for its interest rate swaps centrally cleared through London Clearing House ("LCH") and Chicago Mercantile Exchange ("CME") met the legal characteristics of daily settlements of the derivatives rather than collateral.  As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Depending on the net position, the fair value of the single unit of account is reported in other assets or other liabilities on the consolidated balance sheets, as opposed to interest-earning deposits or interest-bearing deposits.  In addition, the expense or income attributable to the variation margin payments for the centrally cleared swaps is reported in noninterest income, specifically within correspondent and capital markets income, as opposed to interest income or interest expense. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.  The table below discloses the net change in all the balance sheet and income statement line items, as well as performance metrics, impacted by the correction from collateralize-to-market to settle-to-market accounting treatment for prior periods.  There was no impact to net income or equity as previously reported.

(2) interest rate risk primarily resulting from the interest rate environment, the number and pace of interest rate increases, 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) volatility in the financial services industry (including failures or rumors of failures of other depository institutions), along with actions taken by governmental agencies to address such turmoil, could affect the ability of depository institutions, including us, to attract and retain depositors and to borrow or raise capital (4) risks relating to the continued impact of the Covid19 pandemic on the Company, including to efficiencies and the control environment due to the changing work environment; (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;

(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) unexpected outflows of uninsured deposits may require us to sell investment securities at a loss; (15) the loss of value of our investment portfolio could negatively impact market perceptions of us and could lead to deposit withdrawals; (16) price risk focusing on changes in market factors that may affect the value of traded instruments in “mark-to-market” portfolios; (17) transaction risk arising from problems with service or product delivery; (18) compliance risk involving risk to earnings or capital resulting from violations of or nonconformance with laws, rules, regulations, prescribed practices, or ethical standards; (19) 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 special FDIC assessments, the Consumer Financial Protection Bureau regulations, and the possibility of changes in accounting standards, policies, principles and practices;
