AUBURN, Alabama – Auburn National Bancorporation (Nasdaq: AUBN) reported record net earnings of $8.8 million, or $2.42 per share for 2018, compared to $7.8 million, or $2.15 per share, for 2017. For the fourth quarter of 2018, the Company reported record quarterly net earnings of $2.4 million, or $0.66 per share, compared to $1.8 million, or $0.50 per share, for the fourth quarter of 2017.

Robert W. Dumas, Chairman, President, and CEO, commented: “We are pleased to report record earnings for 2018. Our full year and fourth quarter results reflect strong asset quality, solid loan growth, and improved net interest margin. In addition to maintaining a strong capital position, the Company paid cash dividends of $0.96 per share during 2018.”

Net interest income (tax-equivalent) was $6.7 million for the fourth quarter of 2018, a 2% increase compared to $6.6 million for the fourth quarter of 2017. This increase was primarily due to loan growth and recent increases in short-term market interest rates. Average loans were $467.4 million in the fourth quarter of 2018, an increase of $13.6 million, or 3%, from the fourth quarter of 2017. The Company’s net interest margin (tax-equivalent) increased to 3.54% in the fourth quarter of 2018, compared to 3.37% for the fourth quarter of 2017, as earning asset yields improved.

The Company had no provision for loan losses for the fourth quarter of 2018, compared to a negative provision for loan losses of $0.4 million for the fourth quarter of 2017. Net recoveries were $5 thousand in the fourth quarter of 2018, compared to $487 thousand in the fourth quarter of 2017 due to the payoff of two non-performing commercial loans.

Noninterest income was $0.8 million in the fourth quarter of 2018 and 2017, respectively. Noninterest expense was $4.4 million in the fourth quarter of 2018 and 2017, respectively.

Income tax expense was $0.6 million for the fourth quarter of 2018, compared to $1.3 million for the fourth quarter of 2017. The Company’s income tax expense for the fourth quarter of 2018 reflects an effective tax rate of 19.81%, compared to 41.00% in the fourth quarter of 2017. The decrease in the effective tax rate was primarily attributable to the 2017 Tax Cuts and Jobs Act, which lowered the Company’s statutory federal tax rate from 34% to 21% in 2018 and required the Company to remeasure the value of its net deferred tax assets by $0.4 million as of December 31, 2017.

The Company paid cash dividends of $0.24 per share in the fourth quarter of 2018. At December 31, 2018, the Bank’s regulatory capital was well above the minimum amounts required to be “well capitalized” under 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, including the presentation and calculation of the efficiency ratio. 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. 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.
