Auburn National Bancorporation, Inc. Reports Record Quarterly Net Earnings

First Quarter 2018 vs. 2017 Highlights

AUBURN, Alabama – Auburn National Bancorporation, Inc. (Nasdaq: AUBN) reported record net earnings of $2.2 million, or $0.60 per share, for the first quarter of 2018, compared to $1.9 million, or $0.52 per share, for the first quarter of 2017.

“We are pleased to report record quarterly earnings for the first quarter of 2018,” said Robert W. Dumas, President and CEO. Mr. Dumas continued, “The Company’s first quarter results reflect an increase in our net interest income and margin compared to the same quarter last year.”

Net interest income (tax-equivalent) was $6.3 million for the first quarter of 2018, a 7% increase compared to $5.9 million for the first quarter of 2017. This increase was primarily due to loan growth. Average loans were up 5.0% to $451.3 million in the first quarter of 2018 compared to $429.8 million in the first quarter of 2017. The Company’s net interest margin (tax-equivalent) increased to 3.29% in the first quarter of 2018, compared to 3.19% for the first quarter of 2017 as earning asset yields improved.

Nonperforming assets were $3.2 million or 0.39% of total assets at March 31, 2018, compared to $2.5 million or 0.29% of total assets at March 31, 2017. Annualized net charge-offs as a percent of average loans were 0.02% for the first quarter of 2018, compared to 0.05% for the first quarter of 2017. The Company recorded no provision for loan losses in the first quarter of 2018 or in the first quarter of 2017. The provision for loan loss is based upon various factors, including the absolute level of loans, loan growth, credit quality and the amount of net charge-offs.

Noninterest income was $0.9 million compared to $0.8 million for the first quarter of 2017. Noninterest expense was $4.4 million compared to $4.1 million in the first quarter of 2017. The increase was primarily due to routine annual increases in salaries and wages of $0.3 million.

Income tax expense was $0.5 million compared to $0.7 million for the first quarter of 2017 reflecting an effective tax rate of 19.74% compared to 27.50% for the first quarter of 2017. The decrease in the effective tax rate was primarily due to the Tax Cuts and Jobs Act, signed into law December 22, 2017, which lowered the Company’s statutory federal tax rate from 34% to 21%.

The Company paid cash dividends of $0.24 per share in the first quarter of 2018, an increase of 4.3% from the same period in 2017. At March 31, 2018, the Bank’s regulatory capital was 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 includes 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.
