Auburn National Bancorporation, Inc. Reports

Fourth Quarter and Full Year Results

Full Year 2025 Highlights:

AUBURN, Alabama – Auburn National Bancorporation (Nasdaq: AUBN) reported net income of $1.7 million, or $0.48 per share, for the fourth quarter of 2025, compared to $2.2 million, or $0.64 per share, for the third quarter of 2025, and $1.6 million, or $0.45 per share, for the fourth quarter of 2024. For the full year 2025, the Company reported net earnings of $7.3 million, or $2.08 per share, compared to $6.4 million, or $1.83 per share, for 2024.

“Our fourth quarter and full year earnings reflect solid growth in our net interest income and margin, including record full year net interest income of $29.7 million,” said David A. Hedges, President and CEO. “Although our provision for credit losses increased, primarily due to two loan relationships, our asset quality, capital, and liquidity remain strong, our outlook for loan growth in 2026 has improved, and we continue to make progress on our digital banking initiatives. I would like to thank our team for all of their efforts in 2025, including their ongoing dedication to serving our customers and communities” said Mr. Hedges.

Net interest income (tax-equivalent) was $7.7 million for the fourth quarter of 2025, compared to $7.6 million in the third quarter of 2025, and $7.0 million for the fourth quarter of 2024. The increase in net interest income was primarily due to improved net interest margin.

Net interest margin (tax-equivalent) was 3.32% in the fourth quarter of 2025, compared to 3.30% in the third quarter of 2025, and 3.09% in the fourth quarter of 2024. The increase in net interest margin was primarily due to improved yields on interest-earning assets, and a decrease in our cost of interest-bearing deposits.

Nonperforming assets were $0.5 million, or 0.05% of total assets, at December 31, 2025, compared to $0.1 million, or 0.01% of total assets at September 30, 2025, and $0.5 million, or 0.05% of total assets, at December 31, 2024.

The Company recorded a provision for credit losses of $783 thousand in the fourth quarter of 2025, compared to a negative provision for credit losses of $255 thousand in the third quarter of 2025, and a negative provision for credit losses of $48 thousand in the fourth quarter of 2024. The provision for credit losses in the fourth quarter of 2025 was primarily due to two borrowing relationships. Net charge-offs were $304 thousand, or 0.22% of average loans on an annualized basis for the fourth quarter of 2025, compared to annualized net charge-offs of $78 thousand, or 0.06% for the third quarter of 2025, and annualized net recoveries of $16 thousand, or (0.01%) for the fourth quarter of 2024. Net charge-offs recognized in the fourth quarter of 2025 primarily related to one of the two borrowing relationships referenced above.

At December 31, 2025, the Company’s allowance for credit losses was $7.2 million, or 1.27% of total loans, compared to $6.7 million, or 1.20% of total loans at September 30, 2025 and $6.9 million, or 1.22% of total loans at December 31, 2024.

Noninterest income was $0.8 million in the fourth quarter of 2025, largely unchanged from the third quarter of 2025 and the fourth quarter of 2024.

Noninterest expense was $5.6 million in the fourth quarter of 2025, compared to $5.8 million in the third quarter of 2025, and $5.5 million in the fourth quarter of 2024. The decrease in noninterest expense compared to the third quarter of 2025 was primarily related to decreases in salaries and benefits expense and net occupancy and equipment expense. The increase compared to the fourth quarter of 2024 was primarily related to increases in other noninterest expense, which was partially offset by decreases in net occupancy and equipment expense.

The provision for income tax expense was $0.5 million for the fourth quarter of 2025, compared to income tax expense of $0.6 million for the third quarter of 2025, and $0.8 million for the fourth quarter of 2024.

The effective tax rate for the fourth quarter of 2025 was 21.50%, compared to 21.86% for the third quarter of 2025, and 34.73% for the fourth quarter of 2024. The provision for income tax expense and the effective tax rate for the fourth quarter of 2024 included discrete tax items which resulted in additional tax expense. Excluding these discrete items, the effective tax rate for the fourth quarter of 2024 would have been 21.55%. The Company’s effective income tax rate otherwise is principally affected by tax-exempt earnings from the Company’s investments in municipal securities, bank-owned life insurance, and New Markets Tax Credits.

Total assets were $1.0 billion at both December 31, 2025 and September 30, 2025, compared to $977.3 million at December 31, 2024. Loans, net of unearned income were $565.3 million at December 31, 2025, compared to $557.9 million at September 30, 2025 and $564.0 million at December 31, 2024. Total deposits were $922.0 million at December 31, 2025, compared to $917.3 million at September 30, 2025 and $895.8 million at December 31, 2024. At December 31, 2025, the Company had $79.7 million of reciprocal deposits sold off-balance sheet, compared to $33.0 million at September 30, 2025, and $74.1 million at December 31, 2024. The Company had no brokered deposits, FHLB advances or other wholesale borrowings outstanding at December 31, 2025, September 30, 2025, or December 31, 2024.

At December 31, 2025, the Company’s consolidated stockholders’ equity (book value) was $92.1 million, or $26.35 per share, compared to $89.6 million, or $25.65 per share at September 30, 2025, and $78.3 million, or $22.41 per share, at December 31, 2024. The increase from September 30, 2025 was primarily driven by net earnings of $1.7 million and other comprehensive income of $1.7 million due to a decrease in unrealized losses on securities available-for-sale, net of tax, which was partially offset by cash dividends paid of $0.9 million. The increase from December 31, 2024 was primarily driven by net earnings of $7.3 million, and other comprehensive income of $10.2 million due to a decrease in unrealized losses on securities available-for-sale, net of tax, which was partially offset by cash dividends paid of $3.8 million. Unrealized losses on securities do not affect the Bank’s capital for regulatory capital purposes.

The Company’s tangible common equity (“TCE”) ratio or total equity to total assets ratio was 9.04% at December 31, 2025, compared to 8.86% at September 30, 2025, and 8.01% at December 31, 2024. 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.

The Company paid cash dividends of $0.27 per share in the fourth quarter of 2025. At December 31, 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.
