PRESS RELEASE

ATLANTIC CAPITAL BANCSHARES, INC. REPORTS FIRST QUARTER 2020 RESULTS

Atlanta, GA – April 23, 2020 – Atlantic Capital Bancshares, Inc. (NASDAQ: ACBI) announced net income from continuing operations for the quarter ended March 31, 2020 of $2.1 million, or $0.10 per diluted share, compared to $6.4 million, or $0.26 per diluted share, for the first quarter of 2019 and $7.1 million, or $0.32 per diluted share, for the fourth quarter of 2019. The decrease in net income was predominantly driven by increases in credit reserves in anticipation of the expected impact from the economic slowdown from COVID-19.  

“Atlantic Capital entered the COVID-19 crisis in a position of strength with solid first quarter operating results, a fortress balance sheet, and sound business continuity plans. With that strength, our company will provide needed assistance to businesses in our community, add new client relationships, and strive to continue to build meaningful shareholder value through the crisis.” remarked Douglas Williams, President and Chief Executive Officer.

Response to COVID-19 

As the COVID-19 pandemic affected all areas of economic and social life, Atlantic Capital responded with measures to protect the health of its community, customers and associates. The Company implemented work-from-home initiatives for employees when possible, ceased non-essential business related travel, and began regular meetings of its executive leadership and incident response teams to direct the Company’s response to the ever-changing environment. Each week, Doug Williams and his executive leadership team host an internal company-wide conference call to communicate the latest developments, answer teammate questions, and gather information from teammates based on the challenges their relationship customers are facing. 

In addition, Atlantic Capital has taken the following steps to assist borrowers during these challenging times, consistent with sound banking practice:

Our goal is to continue to support our community of customers and prospective customers while maintaining our historically cautious approach to new loan underwriting. With reliable core deposit funding, solid balance sheet liquidity, a strong capital position, and access to significant wholesale funding, Atlantic Capital anticipates adequate funding capacity for future lending needs.

First Quarter Highlights(1)

Income Statement

Taxable equivalent net interest income from continuing operations totaled $21.2 million for the first quarter of 2020, an increase of $679,000, or 3.3%, from the first quarter of 2019, and an increase of $469,000, or 9.0% annualized, from the fourth quarter of 2019. The linked quarter increase in net interest income was primarily driven by a decrease in the cost of interest bearing liabilities offset by a decrease in loan yields. 

Taxable equivalent net interest margin from continuing operations was 3.41% in the first quarter of 2020, a decrease of 33 basis points from the first quarter of 2019 and an increase of 3 basis points from the fourth quarter of 2019. The linked quarter increase was primarily the result of a drop in the cost of interest bearing deposits and an increase in the yield on investment securities. This was partially offset by a decrease in loan yields. 

The yield on loans from continuing operations in the first quarter of 2020 was 4.77%, a decrease of 63 basis points from the first quarter of 2019 and a decrease of 18 basis points from the fourth quarter of 2019. The decrease in loan yields was due primarily to the repricing of variable rate loans as a result of declines in short term interest rates during 2019 and 2020.

The taxable equivalent yield on investment securities in the first quarter of 2020 was 2.84%, an increase of 7 basis points from the first quarter of 2019 and an increase of 21 basis points from the fourth quarter of 2019. The increase in taxable equivalent investment portfolio yields was primarily the result of municipal bond purchases in 2019 and 2020, many of which were non-taxable.    

The cost of deposits from continuing operations in the first quarter of 2020 was 0.75%, a decrease of 34 basis points from the first quarter of 2019 and a decrease of 15 basis points from the fourth quarter of 2019. The cost of interest bearing deposits from continuing operations decreased 52 basis points to 1.09% from the first quarter of 2019, and decreased 27 basis points from the fourth quarter of 2019.

The provision for credit losses for continuing operations was $8.1 million in the first quarter of 2020 compared to $814,000 in the first quarter of 2019 and $787,000 in the fourth quarter of 2019. The provision for credit losses in the first quarter of 2020 included a $7.4 million provision for loan losses and a $671,000 provision for unfunded commitments. The provision increased primarily as a response to the expected impact from the economic slowdown from COVID-19.

Noninterest income from continuing operations totaled $2.4 million in the first quarter of 2020 compared to $2.3 million in the first quarter of 2019 and $2.7 million in the fourth quarter of 2019. Service charge income in the first quarter of 2020 totaled $1.2 million, an increase of $438,000 or 55.2%, compared to the first quarter of 2019 and an increase of $234,000, or 93.8% annualized, from the fourth quarter of 2019. Continued strong growth in core deposits, particularly in

our payments processing businesses, drove the increases in service charge income. SBA income totaled $414,000, a decrease from $1.1 million in the first quarter of 2019 and $846,000 in the fourth quarter of 2019, primarily from lower SBA origination volume and a decrease in loan premiums during the quarter. 

Noninterest expense from continuing operations totaled $12.9 million in the first quarter of 2020, a decrease of $918,000 compared to the first quarter of 2019 and $505,000 compared to the fourth quarter of 2019. Salaries and employee benefits totaled $8.5 million in the first quarter of 2020, unchanged from the previous quarter as the higher first quarter benefits costs were offset by lower incentive accruals. 

The effective tax rate from continuing operations for the first quarter of 2020 was 13.3% compared to 21.3% for the full year of 2019, and was impacted by lower pretax earnings as well as increased non-taxable securities income from municipal bonds.

Balance Sheet

Total loans held for investment were $1.93 billion at March 31, 2020, an increase of $198.4 million, or 11.4%, from March 31, 2019 and an increase of $59.4 million, or 12.7% annualized, from December 31, 2019. Commercial and industrial loans were $760.0 million at March 31, 2020, an increase of 11.9% from March 31, 2019 and 31.2% annualized from December 31, 2019. The increase from December 31, 2019 was primarily due to organic growth across different areas of the Company. Mortgage warehouse loan participations decreased to zero as we exited the business during the first quarter of 2020. Consumer loans increased $20.4 million from December 31, 2019 to $58.2 million at March 31, 2020, due to the growth in a partnership with a fintech firm that offers CD-secured loans to its customers. 

On January 1, 2020, the Company adopted the CECL accounting standard, which resulted in a day one reduction of $854,000 to the allowance for loan losses offset by an increase of $1.3 million to the allowance for unfunded commitments. The allowance for loan losses totaled $18.5 million as of December 31, 2019, was reduced by $854,000 due to CECL adoption, was increased by $7.4 million related to the first quarter 2020 provision, and ended the quarter at $24.9 million. The allowance for unfunded commitments totaled $892,000 at December 31, 2019, was increased by $1.3 million due to CECL adoption, was increased by $671,000 related to the first quarter 2020 provision, and ended the quarter at $2.8 million. At March 31, 2020, the combined allowance for credit losses for loans and unfunded commitments was $27.7 million, compared to $19.4 million at December 31, 2019.

The allowance for loan losses was 1.29% of total loans held for investment at March 31, 2020, compared to 0.99% at December 31, 2019. The increase reflects the impact of COVID-19 on the economic forecast used in the estimation of expected credit losses. Non-performing assets from continuing operations totaled $7.3 million, or 0.27% of total assets, as of March 31, 2020, compared to 0.34% of total assets as of March 31, 2019 and 0.26% of total assets as of December 31, 2019. 

Total average deposits from continuing operations were $2.25 billion for the first quarter of 2020, an increase of $460.7 million, or 25.7%, from the first quarter of 2019 and an increase of $107.9 million, or 20.1% annualized, from the fourth quarter of 2019. Noninterest bearing deposits were 31.6% of total average deposits from continuing operations in the first quarter of 2020, compared to 32.1% in the first quarter of 2019 and 33.5% in the fourth quarter of 2019.

Tangible common equity to tangible assets was 11.6% at March 31, 2020, an increase from 10.6% at December 31, 2019 due to the elevated levels of cash related to year-end deposits at December 31, 2019. The estimated total risk based capital ratio was 14.9% at March 31, 2020 compared to 13.7% at March 31, 2019 and 15.0% at December 31, 2019.
