Auburn National Bancorporation, Inc. Reports First Quarter Net Earnings

First Quarter 2016 Highlights:

• Record quarterly net earnings of $2.2 million, or $0.60 per share

• Earnings per share increased 17.6% compared to first quarter 2015

• Resolution of nonperforming loan results in $1.2 million recovery to the allowance for loan losses and a negative provision for loan losses of $0.6 million

• Average loans increased $27.4 million or 7% compared to first quarter 2015

AUBURN, Alabama – Auburn National Bancorporation, Inc. (Nasdaq: AUBN) reported net earnings of $2.2 million, or $0.60 per share, for the first quarter of 2016, compared to $1.9 million, or $0.51 per share, for the first quarter of 2015.

“The Company’s first quarter results reflect a significant recovery on one nonperforming loan and continued growth in net interest income,” said E.L. Spencer, Jr., President, CEO and Chairman of the Board.

Net interest income (tax-equivalent) was $6.0 million for the first quarter of 2016, an increase of 3% compared to the first quarter of 2015. This increase was primarily due to a reduction in interest expense as the Company repaid higher-cost wholesale funding sources and lowered its deposit costs. Additionally, the Company continued its efforts to increase earnings by shifting its asset mix through loan growth. Average loans were $429.5 million in the first quarter of 2016, an increase of $29.4 million or 7%, from the first quarter of 2015. Average deposits were $726.4 million in the first quarter of 2016, an increase of $20.6 million or 3%, from the first quarter of 2015.

The Company recorded a negative provision for loan losses of $0.6 million for the first quarter of 2016, compared to no provision for loan losses for the first quarter of 2015. Annualized net recoveries as a percent of average loans were 1.01% for the first quarter of 2016, compared to net charge-offs as a percent of average loans of 0.11% for the first quarter of 2015. The Company recognized a recovery of $1.2 million from the payoff of one nonperforming construction and land development loan during the first quarter of 2016.

Noninterest income was $0.8 million for the first quarter of 2016, compared to $1.3 million in the first quarter of 2015. The decrease was primarily due to $0.3 million in non-taxable death benefits from bank-owned life insurance that were received in the first quarter of 2015, compared to none in the first quarter of 2016, and a decrease in mortgage lending of $0.2 million as mortgage loan production declined.

Noninterest expense was $4.1 million in the first quarter of 2016, compared to $4.3 million in the first quarter of 2015. The decrease was primarily due to no prepayment penalties on long-term debt incurred in the first quarter of 2016 compared to $0.4 million incurred in the first quarter of 2015 when the Company repaid $5.0 million of long-term debt with an interest rate of 3.59%. This decrease was partially offset by a $0.2 million increase in salaries and benefits due to normal annual increases.

Income tax expense was $0.8 million for the first quarter of 2016, compared to $0.7 million in the first quarter of 2015. The Company’s income tax expense for the first quarter of 2016 reflects an effective income tax rate of 27.50%, compared to 26.40% for the first quarter of 2015. The increase in the effective tax rate is primarily due to a decrease in tax preference items such as income from bank-owned life insurance. The Company’s income tax expense is principally affected by tax-exempt earnings on municipal securities investments and bank-owned life insurance.

In the first quarter of 2016, the Company paid cash dividends of $0.8 million, or $0.225 per share. At March 31, 2016, 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 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.
