EXHIBIT 99.1 American River Bankshares Announces First Quarter 2007 Earnings Sacramento, CA, April 19, 2007 - American River Bankshares (NASDAQ - GS: AMRB) today reported net income for the first quarter of 2007 of $2,086,000, a 7.0% decrease from $2,243,000 for the quarter ended March 31, 2006. Diluted earnings per share for the first quarter of 2007 were unchanged at $0.37 per share from the first quarter of 2006. "The primary focus of our strategic plan remains to grow American River Bankshares' profitability, which means making prudent decisions for long-term success," said David Taber, President and CEO of American River Bankshares. "Our financial metrics continue to differentiate our Company as a solid performer." Net interest income for the first quarter of 2007 decreased 3.6% to $6,547,000 from $6,792,000 for the first quarter of 2006. Interest income for the first quarter of 2007 increased 3.8% to $9,464,000 from $9,117,000 for the first quarter of 2006. Average earning assets decreased $11,365,000 (2.1%) from the first quarter of 2006 to the first quarter of 2007; the decrease is mainly the result of a planned reduction in the investment portfolio. The proceeds were primarily used to pay down short-term borrowings. The average level of loans increased quarter over quarter by $16,841,000 (4.5%), which helped to increase the interest income for the quarter. Although borrowings were down, interest expense for the first quarter of 2007 increased 25.5% to $2,917,000 from $2,325,000 for the first quarter of 2006. This increase is primarily related to increased interest rates as a direct result of the higher overall rate environment. The average yield on interest bearing liabilities increased 72 basis points from 2.46% during the first quarter of 2006 to 3.18% during the first quarter of 2007. Noninterest income for the first quarter of 2007 increased 1.1% to $641,000 from $634,000 for the first quarter of 2006.
