Auburn National Bancorporation, Inc. Reports Third Quarter Net Earnings

Third Quarter 2025 Highlights:

AUBURN, Alabama – Auburn National Bancorporation, Inc. (Nasdaq: AUBN) reported net earnings of $2.2 million, or $0.64 per share, for the third quarter of 2025, compared to $1.8 million, or $0.52 per share, for the second quarter of 2025, and $1.7 million, or $0.50 per share, for the third quarter of 2024. Net earnings were $5.6 million, or $1.60 per share, for the first nine months of 2025, compared to $4.8 million, or $1.38 per share, for the first nine months of 2024.

“Our third quarter results reflect strong credit quality and continued improvement in our net interest margin,” said David A. Hedges, President and CEO. “Also, we are pleased to report progress on our digital initiatives as we recently rolled out online account opening for certain deposit products. We believe this is an important step in enhancing convenience and expanding access to our banking services,” continued Mr. Hedges.

Net interest income (tax-equivalent) was $7.6 million in the third quarter of 2025, compared to $7.4 million in the second quarter of 2025, and $6.8 million in the third quarter of 2024. The increase was due to growth in average interest-earning assets and improvements in our net interest margin.

Net interest margin (tax-equivalent) was 3.30% in the third quarter of 2025, compared to 3.27% in the second quarter of 2025, and 3.05% in the third quarter of 2024. The increase compared to the second quarter of 2025 was primarily due to improved yields on interest-earning assets. The increase compared to the third quarter of 2024 was primarily due to improved yields on interest-earning assets, and a decrease in our cost of interest-bearing deposits.

Nonperforming assets were $0.1 million, or 0.01% of total assets, at September 30, 2025, compared to $0.3 million, or 0.03% at June 30, 2025, and $0.8 million, or 0.08% of total assets, at September 30, 2024.

The Company recorded a negative provision for credit losses of $255 thousand in the third quarter of 2025, compared to a charge to provision for credit losses of $113 thousand in the second quarter of 2025 and a negative provision for credit losses of $127 thousand in the third quarter of 2024. The provision for credit losses is affected by organic loan growth in our loan portfolio, our internal assessment of the credit quality of the loan portfolio, our expectations about future economic conditions and net charge-offs.

At September 30, 2025, the Company’s allowance for credit losses was $6.7 million, or 1.20% of total loans, compared to $7.0 million, or 1.24% of total loans, at June 30, 2025, and $6.9 million, or 1.22% of total loans, at September 30, 2024.

Noninterest income was $0.8 million for the third quarter of 2025, unchanged from the second quarter of 2025, and the third quarter of 2024.

Noninterest expense was $5.8 million for the third quarter of 2025, compared to $5.7 million for the second quarter of 2025, and $5.5 million in the third quarter of 2024. The increase from the second quarter of 2025 was primarily related to increases in salaries and benefits expense. The increase compared to the third quarter of 2024 was primarily due to increases in salaries and benefits expense and other noninterest expense.

The provision for income tax expense was $0.6 million for the third quarter of 2025, compared to $0.5 million for both the second quarter of 2025, and the third quarter of 2024.

The effective tax rate for the third quarter of 2025 was 21.86%, compared to 20.92% for the second quarter of 2025 and 23.46% for the third quarter of 2024. The Company’s effective income tax rate is principally affected by tax-exempt earnings from the Company’s investments in municipal securities and loans, bank-owned life insurance, and New Markets Tax Credits.

Total assets were $1.0 billion at September 30, 2025 and June 30, 2025 and $990.1 million at September 30, 2024. Loans, net of unearned income were $557.9 million at September 30, 2025, compared to $562.7 million at June 30, 2025 and $565.7 million at September 30, 2024. Total deposits were $917.3 million at September 30, 2025, compared to $939.9 million at June 30, 2025, and $901.7 million at September 30, 2024. The decrease in deposits compared to June 30, 2025 was primarily due to fluctuations in reciprocal customer deposits sold through Intrafi network. At September 30, 2025 the Company had $33.0 million reciprocal deposits sold, compared to none at June 30, 2025 and $37.8 million at September 30, 2024. The increase in deposits compared to September 30, 2024 was primarily related to growth in interest-bearing deposits of $19.0 million, which was partially offset by a decrease of $3.5 million in noninterest-bearing deposits. The Company had no FHLB advances or other wholesale funding outstanding at September 30, 2025, June 30, 2025, or September 30, 2024.

At September 30, 2025, the Company’s consolidated stockholders’ equity (book value) was $89.6 million or $25.65 per share, compared to $86.1 million, or $24.64 per share, at June 30, 2025, and $84.3 million, or $24.14 per share, at September 30, 2024. The increase from June 30, 2025 was primarily driven by net earnings of $2.2 million and other comprehensive income of $2.2 million due to a decrease in unrealized losses on securities available-for-sale, net of tax. These increases in stockholders’ equity were partially offset by cash dividends paid of $0.9 million.

All of the Company’s marketable securities are classified as available-for-sale. Therefore, any changes in the fair value of the Company’s securities portfolio are reflected in total equity, net of tax, under generally accepted accounting principles. Unrealized losses on our securities portfolio vary with market interest rates and do not affect our capital for regulatory capital purposes.

The Company’s tangible common equity (“TCE”) ratio or total equity to total assets ratio was 8.86% at September 30, 2025, compared to 8.36% at June 30, 2025, and 8.52% at September 30, 2024.

The Company paid cash dividends of $0.27 per share in the third quarter of 2025. At September 30, 2025, 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.
