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, 2012, consolidated net income was $1,352,000, while consolidated net income available to common shareholders was $1,238,000, or $0.16 per diluted common share. This compared to net income of $1,450,000 and net income available to common shareholders of $1,239,000, or $0.16 per diluted common share for the same period a year ago.

Net interest income reflected a slight decrease of $88,000 or 1.4% to $6.2 million for the three months ended June 30, 2012, compared to $6.3 million for the same period last year. Year-to-date net interest income remained essentially flat at $12.5 million in both years.  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, 2012 was 4.73%, compared to 4.86% for the same period last year.

Non interest expense for the quarter and six month period ended June 30, 2012 totaled $4.6 million and $9.2 million, respectively, a slight increase over the $4.4 million and $8.9 million for the comparable periods in 2011. This increase was primarily due to additional salary and overhead costs associated with recent branch additions.

Non-performing assets as of June 30, 2012 were $7.2 million, or 1.20% of assets.  This is up from $6.7 million, or 1.12% at March 31, 2012.  The increase reflects the classification of one additional loan relationship as non-accrual.  Non-performing assets remain at favorable levels compared to the same period last year of $9.2 million, or 1.62%.

The provision for loan losses during the three months ended June 30, 2012, remained at $300,000, and unchanged from the same period of the previous year.  The ratio of loan loss reserves to gross loans for the three months ended June 30, 2012 was 2.05%.

Total assets were $596.4 million at June 30, 2012, an increase of $24.2 million, or 4.2%, from June 30, 2011. The Company’s total deposits were $526.4 million as of June 30, 2012, an increase of $30.2 million, or 6.1% over June 30, 2011.  Gross loans remained unchanged at $390.5 million as of June 30, 2012, compared to June 30, 2011.

“Though earnings remain solid in a difficult economic environment, we have not become complacent.  Faced with downward pressure on earning asset yield, corresponding to low interest rates and limited loan demand, we remain diligent in our business development efforts. The relationships we forge today will yield quality loans in the future,” stated Ron Martin, CEO.

The Company 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.
