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, 2011, consolidated net income was $1,450,000, while consolidated net income available to common shareholders was $1,239,000, or $0.16 per diluted common share. This compared favorably to net income available to common shareholders of $828,000, or $0.11 per diluted common share for the same period a year ago.

Net interest income remained stable increasing by $56,000 or 0.9% to $6.3 million for the three months ended June 30, 2011, compared to $6.2 million for the same period last year. Year-to-date net interest income increased $201,000 from the previous year to $12.5 million.

Non interest expense for the quarter and six month period ended June 30, 2011 totaled $4.4 million and $8.9 million, respectively, a slight increase over the $4.3 million and $8.8 million for the comparable periods in 2010. This increase was primarily due to the additional salary and overhead costs associated with new branch openings.

The Company has continued to experience solid reductions in non-performing assets in the past year.  As of June 30, 2011, non-performing assets to total assets are 1.62%, or $9.2 million, down from 2.29%, or $11.9 million for the same period a year ago, and also down from the 2.02%, or $11.4 million at March 31, 2011. As of June 30, 2011, seven loan relationships were on non-accrual status totaling $9.0 million.  OREO carrying balances outstanding were reduced to $244,000 as of June 30, 2011, after write downs totaling $291,000 were recorded in the first six months of 2011.

The provision for loan losses during the three months ended June 30, 2011, was $300,000, compared to $1.0 million during the same quarter of last year. However, in the last 12 months the ratio of loan loss reserves to gross loans has been increased from 1.85% to 2.20%.

Total assets were $572.3 million at June 30, 2011, an increase of $53.1 million, or 10.2%, from June 30, 2010. The Bank’s total deposits were $496.2 million as of June 30, 2011, an increase of $60.5 million, or 13.9% over June 30, 2010.  Gross loans decreased by $20.5 million, to $390.5 million as of June 30, 2011, a decrease of 5.0% from June 30, 2010.

“We are pleased with our 2011 performance thus far and are excited to be in a position to seize some opportunities within our footprint.  Our ability to expand and open two new branches this year, in Modesto and Manteca, is evidence of the sustainable strength of Oak Valley Community Bank,” stated Ron Martin, CEO.

The Company currently operates through 13 branches in Oakdale, Sonora, Turlock, Stockton, Patterson, Ripon, Escalon, three branches in Modesto; and three branches in their Eastern Sierra Division, which includes Bridgeport, Mammoth Lakes, and Bishop. Their recently opened McHenry Branch in Modesto is the first of two planned for 2011. The second is slated to open this fall in Manteca.
