Auburn National Bancorporation, Inc. Reports

Record Full Year Net Earnings of $10.3 million, or $2.95 per share and

Record Quarterly Net Earnings of $4.5 million, or $1.27 per share

Fourth Quarter 2022 Highlights:

AUBURN, Alabama – Auburn National Bancorporation (Nasdaq: AUBN) reported record quarterly net earnings of $4.5 million, or $1.27 per share, for the fourth quarter of 2022, compared to $1.9 million, or $0.53 per share, for the fourth quarter of 2021. For the full year 2022, the Company reported record net earnings of $10.3 million, or $2.95 per share, compared to $8.0 million, or $2.27 per share, for 2021.

“We had record earnings for the fourth quarter and full year 2022 partly due to a couple of notable non-routine items” said David A. Hedges, President and CEO. “However, we saw strong revenue growth as our net interest income and margin continued to expand. In addition to solid loan growth, our net interest margin continued to benefit from our low-cost core deposit base. While 2023 will present new opportunities and challenges, we remain confident that our long-term approach and philosophy of knowing and caring for our customers, maintaining exceptional asset quality, and supporting our communities will enable us to continue to generate value for our shareholders,” said Mr. Hedges.

Total revenue increased by $4.3 million, or 62%, in the fourth quarter of 2022, compared to the fourth quarter of 2021. This increase was primarily related to a $3.2 million gain on the sale of land. Excluding the impact of this gain, total revenue increased by $1.1 million, or 15%, in the fourth quarter of 2022, compared to the fourth quarter of 2021.

Net interest income (tax-equivalent) was $7.6 million for the fourth quarter of 2022, an increase of 23% compared to $6.2 million for the fourth quarter of 2021. This increase was primarily due to improvements in the Company’s net interest margin. The Company’s net interest margin (tax-equivalent) was 3.27% in the fourth quarter of 2022 compared to 2.45% in the fourth quarter of 2021. This increase was primarily due to a more favorable asset mix and higher yields on interest earning assets, while the cost of funds only increased 7 basis points to 0.43%.

Nonperforming assets were $2.7 million, or 0.27% of total assets, at December 31, 2022, compared to $0.3 million, or 0.03% of total assets, at September 30, 2022 and $0.8 million, or 0.07% of total assets, at December 31, 2021. The increase in nonperforming assets was primarily due to the downgrade of one borrowing relationship with a recorded investment of $2.6 million at December 31, 2022.

At December 31, 2022, the Company’s allowance for loan losses was $5.8 million, or 1.14% of total loans, compared to $5.0 million, or 1.05% at September 30, 2022 and $4.9 million, or 1.08% of total loans, at December 31, 2021. At December 31, 2022, the Company’s recorded investment in loans considered impaired was $2.6 million with a corresponding valuation allowance (included in the allowance for loan losses) of $0.5 million, compared to a recorded investment in loans considered impaired of $0.2 million with no corresponding valuation allowance at both September 30, 2022 and December 31, 2021.

The Company recorded a provision for loan losses of $1.0 million in the fourth quarter of 2022, compared to no provision for loan losses in the fourth quarter of 2021. The increase in provision for loan losses was primarily due to loan growth and the downgrade of one borrowing relationship. Net charge-offs were $0.2 million, or 0.16% of average loans on an annualized basis for the fourth quarter in both of 2022 and 2021. Net charge-offs recognized in the fourth quarter of 2022 primarily related to the one borrowing relationship referenced above.

Noninterest income was $3.9 million in the fourth quarter of 2022 compared to $1.0 million for the fourth quarter of 2021. This increase was primarily related to a $3.2 million gain on the sale of land adjacent to Company headquarters. Excluding the impact of this gain, noninterest income was $0.7 million in the fourth quarter of 2022, a 3% decrease compared to the fourth quarter of 2021. The decrease in noninterest income was primarily due to a decrease in mortgage lending income of $0.2 million as refinance activity slowed in our primary market area related to higher market interest rates.

Noninterest expense was $4.4 million in the fourth quarter of 2022 compared to $5.1 million for the fourth quarter of 2021. This decrease was primarily related to the $1.6 million ERC payroll tax credit recognized in the fourth quarter of 2022. Excluding the impact of this payroll tax credit, noninterest expense was $6.0 million in the fourth quarter of 2022, a 19% increase compared to the fourth quarter of 2021. The increase in noninterest expense was primarily due to increases in net occupancy and equipment expense of $0.4 million related to the Company’s new headquarters, which opened in June 2022 and salaries and benefits expense of $0.3 million.

Income tax expense was $1.5 million for the fourth quarter of 2022, compared to $0.1 million during fourth quarter of 2021. The Company’s effective tax rate for the fourth quarter of 2022 was 24.56%, compared to 4.74% in the fourth quarter of 2021. This increase was primarily due to increased pre-tax earnings in the fourth quarter of 2022, additional income tax expense of $0.2 million related to the Company’s decision to surrender certain bank-owned life insurance contracts in the fourth quarter of 2022 and an income tax benefit of $0.4 million realized in the fourth quarter of 2021 related to a New Markets Tax Credit investment. The Company’s effective income tax rate is principally impacted by tax-exempt earnings from the Company’s investments in municipal securities, bank-owned life insurance, and New Markets Tax Credits.

At December 31, 2022, the Company’s consolidated stockholders’ equity was $68.0 million, or $19.42 per share, compared to $103.7 million, or 29.46 per share, at December 31, 2021. The decrease from December 31, 2021 was primarily driven by an other comprehensive loss due to the change in unrealized gains/losses on securities available-for-sale, net of tax, during 2022, of $41.8 million. The increase in the unrealized loss on securities was primarily due to increases in market interest rates. These unrealized losses do not affect the Bank’s capital for regulatory capital purposes. At December 31, 2022, the Company’s equity to total assets ratio was 6.65%, compared to 9.39% at December 31, 2021.

The Company paid cash dividends of $0.265 per share in the fourth quarter of 2022, an increase of 2% from the same period in 2021. The Company repurchased 17,183 shares for $0.5 million in 2022. At December 31, 2022, 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.
