Exhibit 99.1 PRESS RELEASE ATLANTIC CAPITAL BANCSHARES, INC. REPORTS SECOND QUARTER 2021 RESULTS Atlanta, GA – July 23, 2021 – Atlantic Capital Bancshares, Inc. (NASDAQ: ACBI) announced net income for the quarter ended June 30, 2021 of $11.8 million, or $0.58 per diluted share, compared to $1.8 million, or $0.09 per diluted share, for the second quarter of 2020 and $13.4 million, or $0.65 per diluted share, for the first quarter of 2021. “Atlantic Capital recorded another quarter of strong and sustainable growth in loans, deposits, and revenue. Our new business pipelines remain robust, our banking teams are executing at a high level, and we expect solid growth through the balance of 2021 and into 2022,” remarked Douglas Williams, President and Chief Executive Officer. Second Quarter Highlights(1) • Total assets were $3.8 billion, compared to $3.7 billion at March 31, 2021 and $2.9 billion at June 30, 2020. • Loans held for investment, excluding Paycheck Protection Program (“PPP”) loans, increased $77.2 million, or 15% annualized, from March 31, 2021 and increased $208.6 million, or 11%, from June 30, 2020. • Quarterly average deposits increased $150.7 million, or 19% annualized, compared to the first quarter of 2021 and increased $897.6 million, or 37%, compared to the second quarter of 2020. • Cost of deposits decreased to 0.10% from 0.12% in the first quarter of 2021 and from 0.22% in the second quarter of 2020. • Tangible book value per common share increased to $16.40 from $15.74 at March 31, 2021 and from $14.72 at June 30, 2020. • Annualized net charge-offs to average loans totaled 0.10% for the second quarter of 2021 and 0.07% for the full year 2021. Non-performing assets to total assets were 0.14% at June 30, 2021. • The allowance for credit losses was 1.27% of total loans held for investment at June 30, 2021, compared to 1.31% at March 31, 2021 and 1.61% at June 30, 2020. • 50,000 shares were repurchased in the second quarter of 2021 totaling $1.3 million at an average price of $25.71. As of June 30, 2021, approximately $1.8 million remained from our $25 million share repurchase program. Income Statement Taxable equivalent net interest income totaled $26.0 million for the second quarter of 2021, an increase of $4.1 million, or 18%, from the second quarter of 2020, and an increase of $2.3 million, or 39% annualized, from the first quarter of 2021. The second quarter of 2021 included $3.0 million in PPP loan income compared to $696,000 in the second quarter of 2020 and $2.2 million in the first quarter of 2021. The second quarter of 2021 also included $671,000 in interest income related to the receipt of an investment prepayment penalty and the accelerated accretion of a loan discount upon payoff. (1) Commentary is on a fully taxable-equivalent basis unless otherwise noted. Consistent with SEC guidance in Industry Guide 3 that contemplates the calculation of tax-exempt income on a tax equivalent basis, net interest income and net interest margin are provided on a fully taxable-equivalent basis, which generally assumes a 21% marginal tax rate. We provide detailed reconciliations in the Non- GAAP Performance and Financial Measures Reconciliation table on page 13.

GRAPHIC

Taxable equivalent net interest margin was 2.91% in the second quarter of 2021, compared to 3.23% in the second quarter of 2020 and 2.81% in the first quarter of 2021. The tax equivalent net interest margin excluding PPP loans was 2.70%, unchanged from the first quarter of 2021. The yield on loans in the second quarter of 2021 was 4.19%, an increase of 32 basis points from the second quarter of 2020 and an increase of 30 basis points from the first quarter of 2021. Excluding PPP loans, the second quarter of 2021 loan yield was 3.95%, an increase of 12 basis points compared to the first quarter of 2021. In addition, loan interest income for the second quarter of 2021 included $405,000 in previously mentioned accelerated discount accretion. The cost of deposits in the second quarter of 2021 was 0.10%, a decrease of 12 basis points from the second quarter of 2020 and a decrease of 2 basis points from the first quarter of 2021. The cost of interest bearing deposits decreased 16 basis points to 0.17% from the second quarter of 2020, and decreased 2 basis points from the first quarter of 2021. In the second quarter of 2021, we recorded a negative provision for credit losses of $933,000 compared to a provision for credit losses of $8.9 million in the second quarter of 2020 and a negative provision for credit losses of $4.5 million in the first quarter of 2021. The second quarter of 2021 provision for credit losses included a negative provision for loan losses of $814,000 and a negative provision for unfunded commitments of $118,000. Noninterest income totaled $3.6 million in the second quarter of 2021 compared to $2.3 million in the second quarter of 2020 and unchanged from the first quarter of 2021. Service charge income in the second quarter of 2021 totaled $1.7 million, an increase of $646,000 compared to the second quarter of 2020, and an increase of $64,000 from the first quarter of 2021. The increase in service charge income was primarily due to growth in our payments and fintech businesses. Noninterest expense totaled $15.2 million in the second quarter of 2021, compared to $12.9 million in the second quarter of 2020 and $15.1 million in the first quarter of 2021. Salaries and employee benefits expense totaled $10.4 million in the second quarter of 2021, unchanged compared to the first quarter of 2021. Balance Sheet Total loans held for investment were $2.3 billion at June 30, 2021, an increase of $80.2 million from June 30, 2020 and a decrease of $35.9 million from March 31, 2021. Loans held for investment, excluding PPP loans, increased $77.2 million, or 15% annualized, from March 31, 2021 and increased $208.6 million, or 11%, from June 30, 2020. The allowance for credit losses was 1.27% of total loans held for investment at June 30, 2021, compared to 1.31% at March 31, 2021. The decrease in the allowance was a result of an improvement in our current expected credit losses, or CECL, economic forecast along with credit rating upgrades for certain criticized and classified loans. Excluding the impact of PPP loans, the allowance for credit losses at June 30, 2021 was 1.33%, compared to 1.45% at March 31, 2021. Total average deposits were $3.3 billion for the second quarter of 2021, an increase of $897.6 million, or 37%, from the second quarter of 2020 and an increase of $150.7 million, or 19% annualized, from the first quarter of 2021. Average noninterest bearing deposits were $1.3 billion for the second quarter of 2021, an increase of $480.4 million, or 59%, from the second quarter of 2020 and an increase of $159.2 million, or 56% annualized, from the first quarter of 2021. Noninterest bearing deposits were 39.2% of total average deposits in the second quarter of 2021, compared to 33.8% in the second quarter of 2020 and 36.0% in the first quarter of 2021. 2

Subsequent Event As announced and further described in a separate press release issued by Atlantic Capital today, Atlantic Capital and South State Corporation, have entered into a merger agreement under which South State will acquire Atlantic Capital in an all stock merger transaction. Conference Call In light of the announcement earlier today of our entry into a merger agreement with South State Corporation, Atlantic Capital and South State will host a joint conference call at 8:00 a.m. ET on Friday, July 23, 2021, to discuss the transaction and the financial results for the quarter ended June 30, 2021. Individuals wishing to participate in the conference call may do so by dialing 1-877-506-9272 from the United States. The call will also be available live via webcast at https://services.choruscall.com/links/ssb210723.html. Non-GAAP Financial Measures Statements included in this press release include non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measures to GAAP financial measures. Atlantic Capital management uses non-GAAP financial measures, including: (i) taxable equivalent interest income; (ii) taxable equivalent net interest income; (iii) loans held for investment excluding PPP loans (iv) loan yield excluding PPP loans; (v) taxable equivalent net interest margin; (vi) taxable equivalent net interest margin excluding PPP loans; (vii) taxable equivalent income before income taxes; (viii) taxable equivalent income tax expense; (ix) tangible common equity to tangible assets; (x) tangible book value per common share, and (xi) allowance for credit losses to loans held for investment excluding PPP loans, in our analysis of the Company's performance. Tangible common equity excludes goodwill from shareholders' equity. Management believes that non-GAAP financial measures provide a greater understanding of ongoing performance and operations and enhance comparability with prior periods. Non-GAAP financial measures should not be considered as an alternative to any measure of performance or financial condition as determined in accordance with GAAP, and investors should consider Atlantic Capital’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 financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP. Non-GAAP financial measures may not be comparable to non- GAAP financial measures presented by other companies.

atlanticcapitalbank.com Forward-Looking Statements Disclaimer and Non-GAAP Financial Information This presentation contains forward-looking statements within the meaning of section 27A of the Securities Act of 1933, as amended, and 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “strive,” “projection,” “would,” and “outlook,” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates, and projections about our industry, management’s beliefs, and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. The following risks, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: The impact of the COVID-19 pandemic and the responses of governmental authorities on our operations, including declines in credit quality, strains on capital and liquidity, fluctuations in our fintech and payments processing business, and declines in deposits; our participation in the Paycheck Protection Program administered by the Small Business Administration (“SBA”); our strategic decision to focus on the greater Atlanta market may not positively impact our financial condition in the expected timeframe, or at all; costs associated with our growth and hiring initiatives in the Atlanta market area; risks associated with geographic concentration, borrower concentration and concentration in commercial real estate and commercial and industrial loans; our strategic decision to increase our focus on SBA and franchise lending may expose us to additional risks associated with these types of lending, including industry concentration risks, our ability to sell the guaranteed portion of SBA loans, the impact of negative economic conditions on small businesses’ ability to repay the non-guaranteed portions of SBA loans, and changes to applicable federal regulations; risks associated with our ability to manage the planned growth of our fintech and payments processing business, including evolving regulations, security risks, and unforeseen increases in transaction volume resulting from changes in our customers’ businesses and changes in the competitive landscape for fintech and payments processing; changes in asset quality and credit risk; the cost and availability of capital; customer acceptance of our products and services; customer borrowing, repayment, investment and deposit practices; the introduction, withdrawal, success and timing of business initiatives; the impact, extent, and timing of technological changes; severe catastrophic events in our geographic area; a weakening of the economies in which we conduct operations may adversely affect our operating results; the U.S. legal and regulatory framework could adversely affect the operating results of the Company; the interest rate environment may compress margins and adversely affect net interest income; our ability to anticipate or respond to interest rate changes correctly and manage interest rate risk presented through unanticipated changes in our interest rate risk position and/or short- and long-term interest rates; changes in trade, monetary and fiscal policies of various governmental bodies and central banks could affect the economic environment in which we operate; our ability to determine accurate values of certain assets and liabilities; adverse developments in securities, public debt, and capital markets, including changes in market liquidity and volatility; unanticipated changes in our liquidity position, including but not limited to our ability to enter the financial markets to manage and respond to any changes to our liquidity position; the impact of the transition from LIBOR and our ability to adequately manage such transition; adequacy of our risk management program; increased competitive pressure due to consolidation in the financial services industry; risks related to security breaches, cybersecurity attacks, and other significant disruptions in our information technology systems; and other risks and factors identified in our most recent annual report on Form 10-K and our other reports filed with or furnished to the Securities and Exchange Commission (“SEC”) from time to time. Statements included in this presentation include non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measures common to GAAP financial measures. Atlantic Capital management uses non-GAAP financial measures, including:(i) taxable equivalent net interest income, (ii) taxable equivalent net interest margin, (iii) tangible book value per common share, (iv) tangible common equity to tangible assets;(v) pre-provision net revenue, (vi) allowance for credit losses to loans held for investment excluding PPP, and (vii) allowance for loan losses to loans held for investment excluding PPP. Tangible common equity excludes goodwill from shareholders’ equity. Management believes that non-GAAP financial measures provide a greater understanding of ongoing performance and operations, and enhance comparability with prior periods. Non-GAAP financial measures should not be considered as an alternative to any measure of performance or financial condition as determined in accordance with GAAP, and investors should consider Atlantic Capital’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 financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP. Non-GAAP financial measures may not be comparable to non-GAAP financial measures presented by other companies. 2
