EXHIBIT 99.1 American River Bankshares Marks its 100th Consecutive Profitable Quarter Sacramento, CA, January 22, 2009 - American River Bankshares (NASDAQ-GS: AMRB) today reported diluted earnings per share ("EPS") for the fourth quarter of 2008 of $0.32, compared to the $0.36 recorded in the fourth quarter of 2007. For the year ended December 31, 2008 diluted EPS was $1.30 compared to $1.39 for the year ended December 31, 2007. Diluted EPS has been adjusted for 5% stock dividends distributed in December 2008 and 2007. Net income for the fourth quarter of 2008 decreased $316,000 (14.8%) to $1,826,000 from $2,142,000 for the fourth quarter of 2007. Net income for the year ended December 31, 2008 decreased $907,000 (10.7%) to $7,571,000 from $8,478,000 for the year ended December 31, 2007. "For the past 25 years, American River Bankshares has remained consistently profitable through three recessions, two wars in Iraq, the S&L crisis and the general ups and downs of the market," said David Taber, President and CEO of American River Bankshares. "As we celebrate our 25th anniversary and 100th consecutive profitable quarter, we take a moment to look back on all we've accomplished for our clients and shareholders, but more importantly, we look forward to our future success." He continued, "Building our Company on common-sense banking fundamentals has served us well over the last 25 years and we intend to rely on these same fundamentals for the next 25." Net Interest Margin Net interest margin as a percentage was 5.04% for the fourth quarter of 2008 compared to 5.14% for the third quarter of 2008 and 5.10% for the fourth quarter of 2007. Net interest income for the fourth quarter of 2008 decreased $296,000 (4.4%) to $6,446,000 from $6,742,000 for the third quarter of 2008 and decreased $120,000 (1.8%) from the fourth quarter of 2007. Interest income for the fourth quarter of 2008 decreased $485,000 (5.6%) to $8,119,000 from $8,604,000 for the third quarter of 2008 and decreased $943,000 (10.4%) from $9,062,000 for the fourth quarter of 2007. Net interest margin for the year ended December 31, 2008 was 5.03% compared to 5.10% for the year ended December 31, 2007. Net interest income for the year ended December 31, 2008 decreased $477,000 (1.8%) to $25,925,000 from $26,402,000 for the year ended December 31, 2007 and interest income decreased $3,925,000 (10.5%) to $33,553,000 from $37,478,000 for the year ended December 31, 2007. The average yield on earning assets declined from 7.01% in the fourth quarter of 2007 to 6.34% for the fourth quarter of 2008. Much of the decline in yields can be attributed to the overall lower interest rate environment in response to the Federal Open Market Committee's (the "FOMC") decreases in the Federal funds rate. Since September of 2007, the "Prime" rate has decreased ten times for a total of 500 basis points resulting in a steady decline in short-term interest rates. The average balance of earning assets remained consistent with only a slight decrease of 0.5% from $517,824,000 in the fourth quarter of 2007 to $515,217,000 in the fourth quarter of 2008. While the overall balance was stable during this period, the Company did see a positive change in mix with an increase in average loans balances offset by a corresponding decrease in average investment securities. Average loan balances were up $24,462,000 (6.2%) to $417,945,000 while average investments securities were down $25,894,000 (21.9%) to $92,422,000. This is a direct result of the Company's decision to use the proceeds from principal reductions, sales, and maturing investment securities to provide funding for loan growth. Foregone interest income during the fourth quarter of 2008 was approximately $125,000, this compares to $272,000 during the fourth quarter of 2007. Overall, the yield on loans during the fourth quarter of 2008 was 6.70% as compared to 7.73% for the fourth quarter of 2007. Page 4 of Page 13 Also reflective of the declining interest rate environment, interest expense for the fourth quarter of 2008 decreased $189,000 (10.2%) to $1,673,000 from $1,862,000 for the third quarter of 2008 and decreased $823,000 (33.0%) from $2,496,000 for the fourth quarter of 2007. For the year ended December 31, 2008, interest expense decreased $3,448,000 (31.1%) to $7,628,000 from $11,076,000 for the year ended December 31, 2007. The average cost of funds decreased from 2.74% in the fourth quarter of 2007 to 1.76% for the fourth quarter of 2008. The average balance of interest bearing liabilities increased 4.8% from $361,289,000 in the fourth quarter of 2007 to $378,529,000 in the fourth quarter of 2008. This increase resulted primarily from an increase in average other borrowings of $37,638,000 over the same period. The increased borrowings were used to fund the increase in loans and offset the decrease in average deposits of $37,985,000; primarily in noninterest demand, interest checking and money market accounts. The Company has taken advantage of the lower borrowing rates available by locking in one to three year funding from its financial partners. Loan Growth and Asset Quality Net loans as of December 31, 2008 increased $17,381,000 (4.4%) to $412,356,000 from $394,975,000 as of December 31, 2007.
