WINTER HAVEN, FL – January 27, 2021 – SouthState Corporation (NASDAQ: SSB) today released its unaudited results of operations and other financial information for the three-month and twelve-month period ended December 31, 2020.

The Company reported consolidated net income of $1.21 per diluted common share for the three months ended December 31, 2020, compared to $1.34 per diluted common share for the three months ended September 30, 2020, and compared to $1.45 per diluted common share one year ago. During the fourth quarter of 2020, the Company incurred $38.8 million in swap termination expense (pre-tax) and $19.8 million in merger-related and branch closure expense (pre-tax). These charges were partially offset by an income tax benefit of $31.5 million related to the ability to carryback tax losses under the CARES Act.

Adjusted net income (non-GAAP) totaled $1.44 per diluted share for the three months ended December 31, 2020, compared to $1.58 per diluted share, in the third quarter of 2020, and compared to $1.48 per diluted share one year ago. Adjusted net income in the fourth quarter of 2020 excludes $16.3 million of merger-related and branch closure costs (after-tax), $31.8 million in swap termination expense (after-tax), and $31.5 million of income tax benefit referenced above. In the third quarter of 2020, adjusted net income excludes $17.4 million in merger-related costs (after-tax).

​

As compared with 3Q 2020:

| ● | Noninterest income declined by $16.9 million due to lower mortgage banking income of $22.9 million, primarily caused by fair value accounting on lower balances in the mortgage pipeline and loans held for sale.

| ● | This decline was partially offset by higher correspondent banking and capital markets income, fees on deposit accounts, and other income.

| ● | Noninterest expense increased by $41.5 million due primarily to $38.8 million swap termination cost. This was incurred on three cash flow hedges, which were terminated in early December.

| ● | Salaries and employee benefits were higher by $4.1 million due primarily to payroll taxes and additional incentives.

| ● | Merger-related and branch consolidation cost declined by $1.8 million.

*Total nonperforming assets now include nonaccrual loans that are purchase credit deteriorated (“PCD loans”). Prior to January 1, 2020, these loans, which were called acquired credit impaired (“ACI”) loans, were excluded from nonperforming assets. The adoption of CECL resulted in the discontinuation of the pool-level accounting for ACI loans and replaced it with loan-level evaluation for PCD nonaccrual status. The Company’s nonperforming loans increased by $21.0 million in the first quarter of 2020 from these loans. The Company has not assumed or taken on any additional risk relative to these assets. With the merger with CSFL on June 7, 2020, the amount of acquired nonaccruals loans increased by approximately $69.9 million during the second quarter of 2020.

Current Expected Credit Losses (“CECL”)

Effective January 1, 2020, the Company adopted ASU 2016-13 (“CECL”), which affects the allowance for credit losses and the liability for unfunded commitments (“UFC”). Below is a table showing the roll forward of the ACL and UFC for the fourth quarter of 2020:

| ● | Net charge offs of NonPCD loans totaled $209,000 for the quarter and for PCD loans totaled $607,000.

| ● | The provision for credit losses recorded during the fourth quarter reflects an $11.2 million decline in the ACL related to PCD loans primarily from $226 million in loan payments.

| ● | The provision for credit losses recorded during the fourth quarter reflects a $29.2 million increase in the ACL related to NonPCD loans primarily from the blending of two forecasted economic scenarios. The use of two forecast scenarios allowed for the consideration of the uncertainty around the rising cases of the COVID19 pandemic and resultant additional expected credit losses in the NonPCD loan portfolio.

| ● | The ACL for unfunded commitments totals $43.4 million, or 0.93% of the unfunded commitment balance compared to 0.94% at September 30, 2020.

Footnotes to tables:

(1) | Loan data excludes mortgage loans held for sale.

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

(3) | Adjusted earnings, adjusted return on average assets, and adjusted return on average equity are non-GAAP measures and exclude the after-tax effect of gains on acquisitions, gains or losses on sales of securities, 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 $19.8 million, $21.7 million, $40.3 million, $4.1 million, and $1.5 million, for the quarters ended December 31, 2020, September 30, 2020, June 30, 2020, March 31, 2020, and December 31, 2019, respectively; (b) securities (losses) gains, net of $35,000, $15,000, and $24,000, for the quarters ended December 31, 2020, September 30, 2020, and December 31, 2019, respectively; (c) FHLB prepayment penalty of $56,000 and $199,000 for the quarters ended December 31, 2020 and June 30, 2020; (d) swap termination expense for the quarter ended December 31, 2020, of $38.8 million; and (e) $31.5 million of tax carryback losses under the CARES Act for the quarter ended December 31, 2020.

(4) | December 31, 2020 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.

(5) | 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.
