Codorus Valley Bancorp, Inc. Reports Earnings

For the Quarter and Year Ended December 31, 2016

YORK, Pa. – Codorus Valley Bancorp, Inc. (Codorus Valley, or the Corporation) (NASDAQ: CVLY), parent company of PeoplesBank, a Codorus Valley Company (PeoplesBank), today announced net income available to common shareholders (earnings) of $3.8 million or $0.46 per share basic and diluted, for the three months ended December 31, 2016, as compared to earnings of $2.7 million or $0.40 per share basic and diluted, for the three months ended December 31, 2015. For the year ended December 31, 2016, the Corporation earned $13.1 million or $1.56 per share basic and $1.55 per share diluted, compared to $11.0 million or $1.68 per share basic and $1.67 per share diluted for the year ended December 31, 2015. The decrease in earnings per share was primarily a result of the 1,746,850 common shares issued in the $34.5 million public offering completed in December 2015.

Chairman, President and CEO Larry J. Miller commented, “2016 was a strong year for Codorus Valley Bancorp, Inc. and PeoplesBank as total loans and deposits reached record levels. Gross loans grew by more than 13 percent in 2016 while total deposits grew more than 15 percent. Additionally, non-interest bearing deposits grew by more than 24 percent year-over-year; this success is a direct result of the hard work and dedication of our associates. We continue to execute on our long-term strategic initiatives, maximize the investments we have made in the expansion of our franchise, and seize upon the opportunities presented as a result of market disruptions.”

Miller continued, “As we enter 2017, we will be expanding our Small Business Administration activities as we deliver the products and services needed by area businesses that drive economic and job growth throughout our community. This, along with many other planned initiatives throughout our core Pennsylvania and Maryland markets, will provide us with the opportunity to continue to grow our franchise.”

The Corporation’s net interest income for the three months ended December 31, 2016 was $14.0 million, an increase of $1.7 million or 14 percent when compared to the net interest income of $12.3 million for the same period in 2015. For the full year of 2016, net interest income was $53.6 million, reflecting an increase of $5.8 million or 12 percent compared to $47.8 million for 2015. The growth for the three months and year ended December 31, 2016 was driven by an increase in interest earning assets, primarily commercial loans. The Corporation’s net interest margin was 3.89 percent for the full year 2016, an increase over the net interest margin of 3.79 percent for the same period in 2015. PeoplesBank continues to have success in growing low cost core deposits, while maintaining reasonable loan yields in a highly competitive pricing environment.

The provision for loan losses for the three months ended December 31, 2016 was $600,000, a $600,000 decrease as compared to the same period in 2015. For the full year of 2016, the provision for loan losses was $3.0 million compared to $3.5 million for the same period in 2015. The decrease in the provision for the fourth quarter and full year was primarily due to a reduction in net charge-offs in 2016 as compared to 2015. The allowance for loan losses to total loans at December 31, 2016 was 1.18% compared to 1.13% as of December 31, 2015.

Noninterest income, excluding gain on sales of investment securities, for the three months ended December 31, 2016 was $2.6 million, an increase of 19 percent compared to noninterest income of $2.2 million during the same period of 2015. For the full year of 2016, noninterest income, excluding gain on sales of investment securities, was $9.8 million, an increase of 15 percent compared to $8.6 million for the same period in 2015. The increase in noninterest income, excluding gain on sales of investment securities, was attributed primarily to increases in gains on sales of loans, service charges on deposit accounts, wealth management income, and income from bank owned life insurance. There were no gains on sales of investment securities for the fourth quarter of 2016 or 2015. Gain on sales of investment securities decreased $298,000 for the full year of 2016 in comparison to 2015.

Noninterest expense was $10.5 million for the fourth quarter of 2016, an increase of 13 percent as compared to noninterest expense of $9.4 million for the fourth quarter of 2015. For the full year of 2016, noninterest expenses totaled $41.6 million, an increase of 11 percent compared to $37.4 million for 2015. Higher personnel, costs associated with other real estate owned, external data processing, debit card processing and marketing expenses accounted for the majority of the increase. The primary driver of the aforementioned increase in noninterest expense was the expansion of our business and consumer banking services in our Maryland and Pennsylvania markets.

Income tax expense for the quarter and year to date periods ended December 31, 2016 were $1.7 million and $5.9 million, respectively, versus $1.2 million and $4.8 million for the same periods in 2015, respectively. The effective tax rate for the year ended December 31, 2016 was 31.0 percent as compared to 30.2 percent for the same period in 2015.
