For Immediate Release

OAK VALLEY BANCORP REPORTS 1^st QUARTER RESULTS

OAKDALE, CA–Oak Valley Bancorp (NASDAQ: OVLY) (the “Company”), the bank holding company for Oak Valley Community Bank and Eastern Sierra Community Bank, recently reported consolidated financial results. For the three months ended March 31, 2017, consolidated net income was $2,207,000, or $0.27 per diluted common share. This compared to consolidated net income of $2,322,000, or $0.29 per diluted common share, for the prior quarter and $1,509,000, or $0.19 per diluted common share, for the same period a year ago.

The increase in net income compared to the first quarter of 2016 was primarily the result of continued loan growth, a reduction in the provision for loan losses, and an increase in non-interest income mainly due to gains on called securities recorded in the first quarter of 2017. Compared to the fourth quarter of 2016, these gains were offset by increased operating costs and provision for income taxes as we recorded one-time tax benefits during the fourth quarter of 2016.

Net interest income for the three months ended March 31, 2017 was $8,082,000, compared to $8,049,000 in the prior quarter and $7,542,000 for the same period last year. The increase is mainly attributable to growth of our loan and investment portfolios. The net interest margin for the three months ended March 31, 2017 was 3.69%, compared to 3.68% for the prior quarter and 3.76% for the same period last year. The year-over-year decrease in loan and investment yields is a direct result of the low interest rate environment, but the Company has been able to mitigate margin compression by deploying low interest earning cash balances into higher yielding loans and investments.

Non-interest expense totaled $6,207,000 for the quarter ended March 31, 2017, compared to $6,017,000 in the previous quarter and $6,187,000 in the same quarter a year ago. The increases are due primarily to an increase in salaries and benefits.

Non-interest income was $1,471,000 for the quarter ended March 31, 2017, compared to $1,242,000 for the prior quarter and $1,037,000 for the same period last year. The increase compared to the prior periods is primarily related to an increase in gains from called investment securities.

“We’re pleased to report another quarter of solid operating results and are optimistic of continued financial performance given the strong loan demand we’ve recently experienced, and the emerging strength and confidence we’re seeing in the communities we serve,” stated Chris Courtney, President and CEO.

Total assets were $989.9 million at March 31, 2017, a decrease of $12.2 million over December 31, 2016 and an increase of $84.1 million over March 31, 2016. Gross loans were $612.9 million at March 31, 2017, an increase of $1.9 million over December 31, 2016, and an increase of $44.7 million over March 31, 2016. The Company’s total deposits were $899.2 million as of March 31, 2017, a decrease of $14.9 million and an increase of $76.7 million from December 31, 2016 and March 31, 2016, respectively.

As of March 31, 2017, non-performing assets were $3.8 million or 0.38% of total assets, compared to $4.2 million or 0.42% of total assets as of December 31, 2016 and $8.8 million or 0.97% of total assets as of March 31, 2016. The decrease in year-over-year non-performing assets compared to the same period one year ago is due primarily to proceeds received for the payoff of one loan relationship which occurred in April 2016 resulting in the reduction of non-performing assets by $3.9 million at that time.

The Company did not record a provision for loan losses during the first quarter of 2017. The allowance for loan losses remained flat at 1.28% of gross loans at March 31, 2017 and December 31, 2016, and decreased slightly from 1.33% at March 31, 2016.
