Exhibit 99.1 ANOTHER EARNINGS RECORD FOR COLUMBIA BANCORP IN THIRD QUARTER 2006 THE DALLES, Ore., Oct. 25 /PRNewswire-FirstCall/ -- Columbia Bancorp (Nasdaq: CBBO), the financial holding company for Columbia River Bank, reported another earnings record in the third quarter of 2006, with $4.2 million in net income, or $0.42 per diluted share. This is an increase of 20% over the same period last year, when the company earned $3.5 million, or $0.35 per diluted share. Key third quarter analytics: -- 3Q06 Return on Average Equity (ROE) was 19.63% -- 3Q06 Return on Average Assets (ROA) was 1.83% -- 3Q06 Net Interest Margin (tax equivalent) (NIM) was 6.44% -- 3Q06 Efficiency Ratio was 56.45% Key year-to-date analytics: -- Return on Average Equity (ROE) was 18.75% -- Return on Average Assets (ROA) was 1.80% -- Net Interest Margin (tax equivalent) (NIM) was 6.47% -- Efficiency Ratio was 54.89% "Columbia Bancorp continues to grow and perform above banks of similar size," said President and CEO, Roger Christensen. "We are pleased with our financial performance and will continue to use that momentum to expand the Bank into new markets and attract additional customers." COMPANY BUSINESS TRENDS The company remains focused on its five areas of emphasis in 2006: -- Operational efficiency -- Well-planned branch expansion -- Balanced deposit and loan growth -- Attractive products, services, and customer convenience -- Loan quality Columbia River Bank President, Craig Ortega, reports progress on the Company's priorities. "The Bank's outstanding operational performance provides a solid platform for our expansion effort. We are pursuing future branch sites to augment our Portland metro footprint. By the end of 2006, we expect to have expanded our Portland area loan production office into a limited service branch located in Lake Oswego, Oregon." Executive Vice President and Chief Banking Officer, Shane Correa stated, "Our Columbia Gorge and Columbia Basin Regions have shown strong deposit growth, despite the nationwide trend of flat deposit growth in community banks." Correa credited the Bank's year-to-date loan growth of 14% primarily due to increases in real estate and construction loans, mainly from the High Desert region. He anticipated, however, that fourth quarter growth could subside due to historical seasonal patterns. INCOME STATEMENT PERFORMANCE Third quarter revenue (net interest income plus non-interest income) grew to $16.5 million, contributing to a year-to-date revenue figure of $46.0 million. Revenue for the third quarter 2005 was $13.6 million, with a year- to-date total of $38.6 million. "Our loan yields have historically exceeded our peer group, and we believe our deposit pricing structure is competitive," said Greg Spear, Executive Vice President and Chief Financial Officer. Net interest income, before the provision of loan losses, continued its climb, ending the quarter at $13.9 million, a 26% increase over last year's third quarter total of $11.1 million. Year-to-date net interest income was $38.6 million, a 25% improvement over the 2005 third quarter year-to-date total of $30.8 million. The tax equivalent net interest margin continues to outperform both the company's expectations and its peer group of banks $500 million to $1 billion in asset size. The third quarter's net interest margin was 6.44%, and 6.47% year-to-date. This compares with 6.01% in the third quarter of 2005, and 5.91% year-to-date last year. In the non-interest income category, the company's third quarter total was $2.6 million, an increase of 4% over last year's third quarter $2.5 million total. Year-to-date figures were $7.3 million for the nine months ended September 30, 2006, and $7.8 million for the same period of 2005, a decrease of 6%. Total non-interest expense for the company was $9.3 million at September 30, 2006, compared to $7.1 million last year, an increase of 31%. Year-to- date, the Bank's non-interest expense totaled $25.2 million, a 22% growth over last year's year-to-date total of $20.7 million. Spear attributes the growth to increased compensation, leasing and depreciation costs associated with recent expansion, as well as increased incentive compensation accrual due to strong performance. We expect growth in non-interest expense to level off in the fourth quarter of 2006. The Bank's efficiency ratio for the third quarter was 56.45%, compared to 52.50% in the third quarter 2005. Year-to-date efficiency ratio at September 30, 2006, was 54.89%, compared to 53.57% at September 30, 2005. The increase in the ratio is a result of the increase in non-interest expense as mentioned above. Since these expenses are expected to flatten in the fourth quarter, further increase in the efficiency ratio is not anticipated. The efficiency ratio, an important measure of productivity in the banking industry, is calculated by dividing non-interest expense by net interest income and non- interest income, which measures overhead costs as a percentage of total revenues. BALANCE SHEET PERFORMANCE The company's loan portfolio continued its strong growth pace, with $784.2 million in total gross loans, a 19% increase over $659.4 million at the end of the third quarter last year. Year-to-date, the Bank has enjoyed a 14% growth in gross loans. Total deposits at September 30, 2006, were $813.0 million, 14% higher than the $714.5 million total at September 30, 2005. Year-to-date, total deposits have grown by 15%. Shareholders' equity was $87.4 million, or $8.78 per outstanding share at the end of the third quarter, up from $74.6 million, or $7.59 per outstanding share, for the like period last year, a 17% increase. Year-to-date, shareholders' equity has grown by 13%. Tangible book value stands at $8.04 per common share, compared to $6.84 per common share at the end of the third quarter 2005. ASSET QUALITY Non-performing assets at September 30, 2006, were $4.9 million, or 0.50% of total assets, compared to $1.4 million, or 0.17% of total assets, at September 30, 2005. The increase in non-performing assets is due to one large account in the aggregate amount of $3.5 million which was placed on non- accrual during the third quarter. Net charge-offs during the third quarter were $85,000, or 0.01% of gross loans, at September 30, 2006, compared to $709,000, or 0.11% of gross loans, during the third quarter of 2005. Allowance for credit losses was $10.7 million, or 1.36% of gross loans, at September 30, 2006, compared to $9.2 million, or 1.40% of gross loans, at September 30, 2005.
