South State Corporation Reports Third Quarter 2020 Results

And Declares Quarterly Cash Dividend

WINTER HAVEN, FL—October 29, 2020—South State Corporation (NASDAQ: SSB) today released its unaudited results of operations and other financial information for the three-month and nine-month period ended September 30, 2020.

The Company reported consolidated net income of $1.34 per diluted common share for the three months ended September 30, 2020, compared to net loss of ($1.96) per diluted common share for the three months ended June 30, 2020, and compared to $1.50 per diluted common share one year ago. Contributing to the net loss in the second quarter of 2020 was the initial provision for credit losses (“PCL”) recorded on acquired non-purchase credit deteriorated (“NonPCD”) loans and unfunded commitments (“UFC”) which totaled $119.1 million, pre-tax, and merger-related costs of $40.3 million, pre-tax related to the June 7, 2020 merger with CenterState Bank Corporation (“CSFL”).

Adjusted net income (non-GAAP) totaled $1.58 per diluted share for the three months ended September 30, 2020, compared to $0.89 per diluted share, in the second quarter of 2020, and compared to $1.49 per diluted share in the year ago period. Adjusted net income in the third quarter of 2020 removes $17.4 million of merger-related costs, after-tax; and in the second quarter of 2020 removed two primary adjustments: (1) the initial PCL on NonPCD loans and UFC of $92.2 million, after-tax, and (2) merger-related costs of $31.2 million, after-tax.

Highlights of the third quarter included:

| ● | Return on Average Equity of 8.3%.

| ● | Return on Average Tangible Common Equity of 14.7% (Non-GAAP); Adjusted Return on Average Tangible Common Equity of 17.1% (Non-GAAP).

| ● | Return on Average Assets (“ROAA”) of 1.00%, and Adjusted ROAA of 1.18% (Non-GAAP).

| ● | Third quarter of 2020 Pre-Provision Net Revenue (“PPNR ”) was $170 million, or 1.79% PPNR ROAA. This compares to the second quarter of 2020, where on a combined historical basis (as if the companies had been merged for the full quarter, Non-GAAP), PPNR of $157 million, or 1.68% PPNR ROAA. The second quarter’s results only include the operations of CSFL for the final 23 days of the quarter.

| ● | Book value per share of $64.34 increased by $0.99 per share from 2Q 2020.

| ● | Tangible book value (“TBV”) per share of $39.83, up $1.50 from 2Q 2020 (Non-GAAP).

| ● | Record quarterly revenue of $385 million (compared to actual prior period and combined historical basis).

| ● | Net interest margin, declined by 2 basis points to 3.22% during 3Q 2020 from 2Q 2020.

| ● | Significant allowance for credit losses and credit marks on the balance sheet representing 2.58% of total loans (excluding PPP loans).

| ● | Net charge-offs of $594,000, or 0.01% annualized.

| ● | As of 10/23/2020, loan deferrals totaled $452.4million, or 1.98% of the total loan portfolio, excluding PPP loans and held for sale loans.

​

“After closing our merger late in the second quarter, we are pleased with our first full quarter of operations as a combined company”, said John C. Corbett, Chief Executive Officer. “Our fee businesses continue to perform well, leading us to another record quarter of revenue. While the current environment includes challenges and uncertainties, we look forward to the future with great optimism.”

Robert R. Hill, Jr., Executive Chairman added, “The CenterState and South State partnership is about the long-term but you can clearly see the progress being made in the short-term. Progress with technology, products, efficiency, and talent all have us uniquely positioned. We are off to a solid start.”

Loan / Deposit Growth

As of September 30, 2020, we have assisted customers with nearly 20,000 Paycheck Protection Program (“PPP”) loans and have an outstanding balance of $2.4 billion. We have recognized $8.5 million in deferred loan fees, net of costs in the income statement during the third quarter of 2020, and $15.9 million on a YTD basis. $53.3 million of net deferred fees remains to be recognized over the life of these loans. During the third quarter, loans (nonacquired and acquired) declined by $261.3 million, or 4.1% annualized. The third quarter decline in loans was centered in construction and development loans and single-family residential mortgage loans. Total deposits increased $12.7 million with core deposit growth totaling $310.6 million, or 4.8% annualized.

Quarterly Cash Dividend

The Company’s Board of Directors declared a common stock dividend of $0.47 per share, payable on November 20, 2020 to shareholders of record as of November 13, 2020.

*Adjusted diluted weighted average common shares was calculated with the result of adjusted net income (non-GAAP).

The Company reported consolidated net income of $95.2 million, or $1.34 per diluted common share for the three-months ended September 30, 2020, an increase of $180.2 million, or $3.30 per diluted common share, from the second quarter of 2020. The net loss in the second quarter of 2020 was the result of the initial PCL recorded on the acquired NonPCD loans and the merger-related cost incurred from the merger with CSFL. Weighted-average diluted shares increased by 27.8 million shares, or 64.1%, compared to the second quarter of 2020, due primarily to the merger with CSFL in early June, in which the Company issued 37.3 million shares. These shares were outstanding all of the third quarter of 2020 compared to only 23 days in the second quarter of 2020. Net interest income increased by $107.8 million in the third quarter of 2020, compared to the second quarter of 2020, due to the full quarter impact of the merger with CSFL in the third quarter of 2020 compared to only 23 days in the second quarter of 2020. Interest income on acquired loans included $22.4 million of loan accretion. The PCL decreased by $121.7 million, due to the PCL on NonPCD loans and unfunded commitments associated with CSFL merger that were recognized in the second quarter of 2020. Noninterest income in was up $60.4 million compared to second quarter of 2020 to $114.8 million in the third quarter of 2020, due to the strong results from mortgage banking (primarily within the secondary market) and correspondent banking and capital markets income. Correspondent banking was added to the Company from the merger with CSFL and contributed $24.4 million in the third quarter of 2020 compared to $8.3 million in the month of June during the second quarter of 2020. Noninterest expense was higher in the third quarter of 2020 compared to the second quarter of 2020 by $61.8 million due primarily to the full quarter impact of the expenses of CSFL. Merger-related expense were lower by $18.6 million compared to the second quarter of 2020 when all professional services were incurred at legal close in early June of 2020. Adjusted noninterest expense was up approximately 59.9% over second quarter 2020, which relates directly to the addition of CSFL operating expense for all of the third quarter of 2020. The efficiency ratio (Non-GAAP) and adjusted efficiency ratio were 61.4% and 55.8% in 3Q 2020, respectively, compared to 80.5% and 61.9% in 2Q 2020, respectively.

Current Expected Credit Losses (“CECL”)

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

The ACL related to all loans totals $440.2 million compared to $434.6 million at June 30, 2020, and was recorded as a contra asset on its own line within the balance sheet, while the liability for UFC of $43.2 million was recorded on its own line in the liabilities section of the balance sheet. The total provision for credit losses recorded in the third quarter of 2020 was $29.8 million, including $22.1 million related to the liability for unfunded commitments (which was the result of a change in the methodology with the merger of CSFL and the Company). In the second quarter of 2020, (including the initial provision for credit losses related to acquired NonPCD loans and UFC from CSFL) the total provision for credit losses was $151.5 million.

Income Tax Expense

During the third quarter of 2020, our effective tax rate decreased to 19.61% from 22.56% in the second quarter of 2020 and from 20.13% in the third quarter of 2019. The primary reason for the decline relates to the fact that the Company was back in a pre-tax income position in 3Q 2020 compared to a pre-tax loss position in 2Q 2020, and the impact of the rate reducing items on the effective tax rate. The lower effective tax rate in 3Q 2020 compared to 3Q 2019 was mainly due to an increase in federal tax credits, as well as additional tax-exempt income resulting from the merger with CSFL. Lastly, an additional income tax benefit was recorded when legacy South State’s deferred taxes were revalued as a result of the merger. This was slightly offset by an increase in pre-tax income compared to the same period in 2019.

*Total nonperforming assets now include nonaccrual loans that are purchase credit deteriorated (“PCD loans”). In prior periods, 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, the amount of acquired nonaccruals loans increased by approximately $69.9 million.

Total nonperforming assets decreased by $15.8 million to $126.2 million, representing 0.33% of total assets, a decrease of 5 basis points compared to June 30, 2020. The decrease was due primarily to the reduction in nonperforming assets acquired, both in loans ($10.4 million) and in OREO ($4.1 million). Non-acquired non-performing assets decreased by $1.3 million during the third quarter of 2020 to $23.3 million at September 30, 2020. The ACL as a percentage of total nonperforming loans was 391% at September 30, 2020, up from 353% of total nonperforming loans at June 30, 2020.

At September 30, 2020, the ACL was $440.2 million, or 1.74%, of period end loans. Additionally, unfunded commitments have a reserve of $43.2 million, or 0.94% of unfunded commitments (off balance sheet). The ACL was $434.6 million, or 1.70%, of period end loans at June 30, 2020. Net charge-offs totaled $594,000, or 0.01%, annualized of average total loans, in the third quarter of 2020 compared to $101,000, or 0.00%, annualized in the second quarter of 2020.

During the third quarter of 2020, the provision for credit losses totaled $29.8 million for the loan portfolio compared to $151.5 million for the provision for credit losses in the second quarter of 2020. The significant provision in the second quarter of 2020 was the result of the merger with CSFL and the initial provision for credit losses recorded on NonPCD loans acquired, the unfunded commitment liability related to CSFL, and the additional PCL related to non-acquired South State loans totaled $28.4 million. This initial PCL on NonPCD acquired loans and UFC totaled $119.1 million. The total provision for credit losses of $29.8 million recorded in the third

quarter of 2020 included $22.1 million related to the liability for unfunded commitments and $7.7 million from the expected lifetime losses of loans outstanding. Prior to the merger, each of CSFL and the Company ran separate CECL models. The CECL calculation at June 30, 2020 was the result of combining the results of the two models. During the third quarter, the Company consolidated into one CECL model. This change led to an increase in the reserve for unfunded commitments since the consolidated model used a differing methodology from that used for 2Q 2020.

Total OREO decreased during the third quarter of 2020 to $13.5 million, a $4.5 million decrease from the balance at June 30, 2020.

​

The net interest margin (“NIM”) declined by 2 basis points to 3.22% at September 30, 2020, from 3.24% at June 30, 2020, and declined from 3.73% from September 30, 2019. These declines were the result of the current low interest rate environment from the COVID-19 pandemic and the stimulus from the CARES Act. The yield on the acquired loan portfolio declined to 4.76% compared 5.08% in the second quarter of 2020, while the non-acquired loan portfolio only declined 1 basis point to 3.83% from 3.84% in the second quarter of 2020. Deposit cost declined by 9 basis points to 20 basis points in the third quarter of 2020. Including the impact of noninterest bearing deposits, the Company’s overall cost of funds declined to 31 basis points for the third quarter of 2020 compared to 37 basis points in the second quarter of 2020, and decreased from 69 basis points in the year ago period. The average balances for each category and the totals increased significantly in the third quarter of 2020, due primarily from the full quarter impact of the CSFL merger compared to only 23 days included in the second quarter of 2020.

Acquired Loans and Loan Accretion

With the adoption of CECL, loan accretion, accretable yield, and the related discounts are now consistently accounted for within the balance sheet and income statement. Acquired loans reflected the following results in the third quarter of 2020:

| ● | Contractual interest income totaled $146.3 million, or 4.13% yield.

| ● | Loan accretion totaled $22.4 million, compared to $10.1 million in the second quarter of 2020. The amount of accretion recognized in third quarter from the CSFL acquired loan portfolio totaled $14.7 million compared to $2.9 million in the second quarter which only included 23 days from the merger closing date.

| ● | Including the loan accretion, total interest income was $168.8 million on acquired loans resulting in 4.76% yield during the third quarter of 2020, down from 5.08% in the second quarter of 2020.

The table below reflects the remaining discount on acquired loans, which will be accreted into loan interest income over the contractual life of the loan and includes the discount recorded from the merger with CSFL, including a third quarter of 2020 measurement period adjustment primarily related to an updated loan valuation (dollars in thousands):

​

Noninterest income totaled $114.8 million for the third quarter of 2020 compared to $54.3 million in the second quarter of 2020, an increase of $60.4 million. This large increase within all categories was due to the inclusion of income for the full quarter from the merger with CSFL compared to only 23 days in the second quarter of 2020. The largest increases were $29.7 million in mortgage banking income and $16.4 million in correspondent banking and capital markets income. Mortgage banking income improved by $23.5 million from the gains within the secondary market, net of commissions; and from $6.2 million of income associated with the MSR, net of the hedge.

Compared to the third quarter of 2019, noninterest income increased by $77.2 million due to the impact of merger with CSFL. Correspondent banking and capital markets income discussed above improved by $25.7 million and mortgage banking income increased by $41.9 million. Secondary market mortgage income was up $39.9 million from the increase in the gain on sale of mortgage loans,

from both higher volume of loans and at higher margins. The other categories of noninterest income all increased, except for recoveries from acquired loans, which now flow through the allowance for credit losses, and resulted in a $1.4 million decrease.

Noninterest expense was $236.9 million in the third quarter of 2020, an increase of $61.8 million from $175.1 million in the second quarter of 2020. The increase was related to the full quarter impact of expense associated with the merger with CSFL (compared to only 23 days in 2Q 2020). Merger-related costs totaled $21.7 million for the quarter and was a decrease of $18.6 million from the second quarter of 2020. Adjusted noninterest expense totaled $215.2 million in 3Q 2020, which was $80.6 million higher than second quarter of 2020, and resulted in an adjusted efficiency ratio of 55.8% compared to 61.9%, in second quarter of 2020.

Compared to the third quarter of 2019, noninterest expense was higher by $140.5 million. The increase was due to the merger with CSFL in June 2020, and the inclusion of the combined company expenses for all of the third quarter of 2020. In addition, the third quarter of 2020 includes $21.7 million of additional merger-related cost. Adjusted noninterest expense (non-GAAP) increased $118.9 million, compared to the third quarter of 2019.

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, 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 $21.7 million, $40.3 million, $4.1 million, and $1.5 million, for the quarters ended September 30, 2020, June 30, 2020, March 31, 2020, and December 31, 2019, respectively; (b) securities (losses) gains, net of $15,000, $24,000, and $437,000, for the quarters ended September 30, 2020, December 31, 2019, and September 30, 2019, respectively; and (c) FHLB prepayment penalty of $199,000 for the quarter ended June 30, 2020.

(4) | September 30, 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.

(6) | Includes loan accretion (interest) income related to the discount on acquired loans of $22.4 million, $10.1 million, $10.9 million $7.4 million, and $8.1 million, respectively, during the five quarters above.

(7) | Adjusted efficiency ratio is calculated by taking the noninterest expense excluding branch consolidation cost and merger cost, pension plan termination and the FHLB prepayment penalty divided by net interest income and noninterest income excluding securities gains (losses).

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 negative economic developments resulting from federal spending cuts and/or one or more federal budget-related impasses or actions; (2) 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; (3) potential deterioration in real estate values; (4) 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; (5) 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; (6) interest risk involving the effect of a change in interest rates on the bank’s earnings, the market value of the bank’s loan and securities portfolios, and the market value of South State’s equity; (7) liquidity risk affecting the bank’s ability to meet its obligations when they come due; (8) risks associated with an anticipated increase in South State’s investment securities portfolio, including risks associated with acquiring and holding investment securities or potentially determining that the amount of investment securities South State desires to acquire are not available on terms acceptable to South State;

(11) compliance risk involving risk to earnings or capital resulting from violations of or nonconformance with laws, rules, regulations, prescribed practices, or ethical standards; (12) 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 recently enacted CARES Act, the Consumer Financial Protection Bureau rules and regulations, and the possibility of changes in accounting standards, policies, principles and practices, including changes in accounting principles relating to loan loss recognition (CECL); (13) strategic risk resulting from adverse business decisions or improper implementation of business decisions; (14) reputation risk that adversely affects earnings or capital arising from negative public opinion; (15) terrorist activities risk that results in loss of consumer confidence and economic disruptions; (16) cybersecurity risk related to the dependence of South State on internal computer systems and the technology of outside service providers, as well as the potential impacts of third party security breaches, subjects each company to potential business disruptions or financial losses resulting from deliberate attacks or unintentional events; (17) greater than expected noninterest expenses; (18) noninterest income risk resulting from the effect of regulations that prohibit financial institutions from charging consumer fees for paying overdrafts on ATM and one-time debit card transactions, unless the consumer consents or opts‑in to the overdraft service for those types of transactions; (19) excessive loan losses; (20) failure to realize synergies and other financial benefits from, and to limit liabilities associated with, the merger with CSFL within the expected time frame, and ownership dilution risk associated with potential acquisitions in which South State’s stock may be issued as consideration for an acquired company; (21) potential deposit attrition, higher than expected costs, customer loss and business disruption associated with the merger with CSFL integration, including, without limitation, and potential difficulties in maintaining relationships with key personnel;

(24) 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; (25) major catastrophes such as earthquakes, floods or other natural or human disasters, including infectious disease outbreaks, including the recent outbreak of the COVID-19 coronavirus, 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 South State and its customers and other constituencies; and (26) other risks related to the merger of South State 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, and (27) other factors that may affect future results of South State and CenterState, as disclosed in South State’s Annual Report on Form 10-K, as amended, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, and CenterState’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, in each case filed by South State or CenterState, as applicable, 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.
