Auburn National Bancorporation, Inc. Reports First Quarter Net Earnings

First Quarter 2021 Results:

AUBURN, Alabama – Auburn National Bancorporation, Inc. (Nasdaq: AUBN) reported net earnings of $2.0 million, or $0.56 per share, for the first quarter of 2021, compared to $1.8 million, or $0.50 per share, for the first quarter of 2020.

“The Company enjoyed strong mortgage revenue and excellent credit quality in the first quarter of 2021. Low interest rates continue to be a challenge, but we are optimistic that the economy will improve in light of the growing number COVID-19 vaccinations and the easing of pandemic-related restrictions in our markets,” said Robert W. Dumas, Chairman, President, and CEO.

“We continue to work with our small businesses who are affected by the pandemic to help them gain access to PPP funds and also to complete the PPP loan forgiveness process. In the first quarter of 2021, we funded $18.7 million Paycheck Protection Program loans for our customers, which helped support approximately 2,600 employees in our markets,” said Mr. Dumas.

Net interest income (tax-equivalent) was $6.1 million for the first quarter of 2021, a 4% decrease compared to $6.3 million for the first quarter of 2020. This decrease was primarily due to net interest margin compression resulting from the Federal Reserve’s interest rate reductions in response to COVID-19.

Net interest margin (tax-equivalent) decreased to 2.66% in the first quarter of 2021, compared to 3.23% for the first quarter of 2020, primarily due to the lower interest rate environment and changes in our asset mix resulting from the significant increase in customer deposits.

The Company recorded no provision for loan losses during the first quarter of 2021, compared to a provision for loan losses of $0.4 million during the first quarter of 2020. At March 31, 2021, the Company’s allowance for loan losses was $5.7 million, or 1.23% of total loans, compared to $5.6 million, or 1.22% of total loans, at December 31, 2020, and $4.9 million, or 1.10% of total loans, at March 31, 2020. Excluding PPP loans, the Company’s allowance for loan losses was 1.31% of total loans at March 31, 2021.

We have identified certain commercial sectors with enhanced risk resulting from the impact of COVID-19. Loans within these sectors represent 86% of the Company’s total COVID-19 related modifications at March 31, 2021. The table below summarizes the loans outstanding for these sectors at March 31, 2021.

At March 31, 2021, we have granted loan payment deferrals or other loan modifications totaling $32.4 million, or 7% of total loans, compared to $112.7 million, or 24% of total loans at June 30, 2020, the first quarterly period we began offering COVID-19 loan modifications. The tables below provide information concerning the composition of these COVID-19 modifications as of March 31, 2021.

COVID-19 Modifications within Commercial Real Estate Segments

Noninterest income was $1.2 million for the first quarter of 2021 and 2020, respectively. For the first quarter of 2021, noninterest income included an increase in mortgage lending income of $0.3 million. The increase was primarily due to an increase in mortgage lending income as lower interest rates for mortgage loans positively affected refinance activity and pricing margins improved. For the first quarter of 2020, noninterest income included $0.3 million in non-taxable death benefits from bank-owned life insurance.

Noninterest expense was $4.7 million for the first quarter of 2021 compared to $4.9 million for the first quarter of 2020. The decrease was primarily due to a reduction of $0.2 million in various expenses related to the redevelopment of the Company’s headquarters in downtown Auburn.

Income tax expense was $0.4 million for the first quarter of 2021 and 2020, respectively. The Company’s effective tax rate for the first quarter of 2021 was 17.41%, compared to 17.80% in the first quarter of 2020.

The Company paid cash dividends of $0.26 per share in the first quarter of 2021, an increase of 2% from the same period in 2020. At March 31, 2021, the Bank’s regulatory capital ratios were well above the minimum amounts required to be “well capitalized” under current regulatory standards.

Explanation of Certain Unaudited Non-GAAP Financial Measures

This press release contains financial information determined by methods other than U.S. generally accepted accounting principles (“GAAP”). The attached financial highlights include certain designated net interest income amounts presented on a tax-equivalent basis, a non-GAAP financial measure, and the presentation and calculation of the efficiency ratio, a non-GAAP measure. Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes the presentation of net interest income on a tax-equivalent basis provides comparability of net interest income from both taxable and tax-exempt sources and facilitates comparability within the industry. Similarly, the efficiency ratio is a common measure that facilitates comparability with other financial institutions. Although the Company believes these non-GAAP financial measures enhance investors’ understanding of its business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. Along with the attached financial highlights, the Company provides reconciliations between the GAAP financial measures and these non-GAAP financial measures.
