OAK VALLEY BANCORP REPORTS 2nd QUARTER RESULTS

OAKDALE, CA – Oak Valley Bancorp (NASDAQ: OVLY), the bank holding company for Oak Valley Community Bank and Eastern Sierra Community Bank, recently reported consolidated financial results. For the three months ended June 30, 2013, consolidated net income available to common shareholders was $1,374,000, or $0.18 per diluted common share. This compared to consolidated net income available to common shareholders of $1,238,000, or $0.16 per diluted common share for the same period a year ago.

Total assets were $644.2 million at June 30, 2013, an increase of $47.8 million, or 8.0%, from June 30, 2012. The Company’s total deposits were $577.1 million as of June 30, 2013, an increase of $50.7 million, or 9.6% over June 30, 2012.  Gross loans remained essentially unchanged at $390.6 million as of June 30, 2013, compared to $390.5 million as of June 30, 2012.

“We are pleased to report another quarter of solid earnings, in the face of continued margin compression,” stated Chris Courtney, President and CEO of the Company and the Bank.  “We remain steadied by the ongoing efforts of our lenders and managers who have worked diligently to retain and strengthen existing relationships, as well as, build new ones.”

Net interest income reflected a decrease of $188,000 or 3.0% to $6.0 million for the three months ended June 30, 2013, compared to $6.2 million for the same period last year.  The low interest rate environment continues to drive loan and investment yields down.  The Company’s net interest margin for the three months ended June 30, 2013 was 4.18%, compared to 4.73% for the same period last year.

Non interest expense for the quarter and six month periods ended June 30, 2013 totaled $4.7 million and $9.4 million, respectively, a slight increase over the $4.6 million and $9.2 million for the comparable periods in 2012. This increase corresponds to growth in full time

equivalent staff from 125 to 134.  Data processing costs associated with increased deposit account activity have also increased.

Non-performing assets as of June 30, 2013 were $4.2 million, or 0.65% of total assets.  This is down from $7.2 million, or 1.20% at June 30, 2012.  The decrease reflects the continued management of the portfolio.

The provision for loan losses during the three months ended June 30, 2013, was $100,000, compared to $300,000 for the same period of the previous year.  The ratio of loan loss reserves to gross loans decreased to 1.94% as of June 30, 2013, compared to 2.05% at June 30, 2012, as a result of the reduction of non-performing assets.

The Bank currently operates through 14 branches in Oakdale, Sonora, Turlock, Stockton, Patterson, Ripon, Escalon, Manteca, three branches in Modesto, and three branches in their Eastern Sierra Division, which includes Bridgeport, Mammoth Lakes, and Bishop.
