​

“We are pleased to begin 2021 with solid results in the first quarter”, said John C. Corbett, Chief Executive Officer. “Our longstanding focus on asset quality has benefited us through this environment, with four consecutive quarters with minimal to no net loan losses. The improvement in the economy and in economic forecasts led us to release loss reserves in the quarter, aiding our net income, though we continue to have a solid reserve position should the economic recovery falter. We are also pleased to have expanded our Correspondent division with the February 1 addition of the Duncan Williams team to the company.”

​

“South State’s balance sheet is strong and continues to strengthen with annualized total deposit growth of 23% for the quarter and Tangible Book Value growth of 10.5% compared to last year,” said Robert R. Hill, Jr., Executive Chairman. “This foundation, coupled with strong fee businesses, has us well-positioned for the future.”

Certain prior period information has been reclassified to conform to the current period presentation, and these reclassifications had no impact on net income or equity as previously reported.

Footnotes to tables:

(1) | Includes loan accretion (interest) income related to the discount on acquired loans of $10.4 m illion, $12.7 million, $22.4 million, $10.1 million and $10.9 million, respectively, during the five quarters above.

(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, FHLB Advances prepayment penalty, initial provision for credit losses on non-PCD loans and unfunded commitments, income tax benefit related to the carryback of tax losses under the CARES Act, swap termination expense, and merger and branch consolidation related expense. 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 and branch consolidation related expense of $10.0 million, $19.8 million, $21.7 million, $40.3 million and $4.1 million, for the quarters ended March 31, 2021, December 31, 2020, September 30, 2020, June 30, 2020 and March 31, 2020, respectively; (b) net securities gains of $35,000 and $15,000 for the quarters ended December 31, 2020 and September 30, 2020, respectively; (c) FHLB prepayment penalty of $56,000 and $199,000 for the quarters ended December 31, 2020 and June 30, 2020, respectively; (d) swap termination expense of $38.8 million for the quarter ended December 31, 2020; (e) tax carryback losses under the CARES Act of $31.5 million for the quarter ended December 31, 2020; and (f) initial provision for credit losses on non-PCD loans and unfunded commitments of $119.1 million for the quarter ended June 30, 2020.

(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 swap termination expense, branch consolidation cost and merger cost, tax carryback losses under the CARES Act, amortization of intangible assets, and the FHLB prepayment penalty divided by net interest income and noninterest income excluding securities gains (losses). The pre-tax amortization expense of intangible assets were $9.2 million, $9.8 million, $9.6 million, $4.7 million and $3.0 million, for the quarters ended March 31, 2021, December 31, 2020, September 30, 2020, June 30, 2020 and March 31, 2020, 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) | March 31, 2021 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.
