Exhibit 99.1 COLUMBIA BANCORP REPORTS STRONG GROWTH IN SECOND QUARTER 2006 THE DALLES, Ore., July 26 /PRNewswire-FirstCall/ -- Columbia Bancorp (Nasdaq: CBBO), the financial holding company for Columbia River Bank, reported another strong quarter of balance sheet growth, including an increase of $96.0 million in total assets and another pronounced increase in net interest margin. Key second quarter analytics: -- Return on Equity (ROE) was 17.57% -- Return on Assets (ROA) was 1.72% -- Net Interest Margin (tax equivalent) (NIM) was 6.60% -- Efficiency Ratio was 53.60% Key year-to-date analytics: -- Total Assets were $952.8 million, a YTD growth rate of 13% -- Gross Loans were $766.6 million, a YTD growth rate of 11% -- Deposits were $777.3 million, a YTD growth rate of 10% -- Return on Equity (ROE) was 18.28% -- Return on Assets (ROA) was 1.78% -- Net Interest Margin (tax equivalent) (NIM) was 6.49% -- Efficiency Ratio was 54.02% Second quarter net income for the Company was $3.6 million, or $0.36 per diluted share, compared to $3.4 million, or $0.34 per diluted share in the second quarter of 2005, a 5% increase in net income. COMPANY BUSINESS TRENDS In late 2005, the Company established five areas of focus for 2006: -- Operational efficiency -- Well-planned branch expansion -- Balanced deposit and loan growth -- Attractive products and services, and customer convenience -- Loan quality Columbia Bancorp President and CEO, Roger Christensen, said while the Company is making progress on all fronts, the branch expansion work continues to pay rewards. "Our Richland, Pasco, Yakima and Sunnyside, Washington, branches are all contributing to our company," he said. Christensen believes the Bank's increased brand awareness and corporate reputation has created opportunities for branch expansion. "We are looking intently at new markets that will bring us closer to additional metropolitan areas that surround our current market area," he said. "We believe moving into those markets will contribute to loan and deposit growth and enable us to surpass the $1.0 billion in assets milestone." While maintaining its investments in infrastructure and technologies as a way to focus on customer convenience and efficiency, the Company continues to see growth in the loan portfolio and retail deposits. "In addition to quality products and services, our objective is to ensure our customer's experience will help us strengthen our relationships," said Shane Correa, Executive Vice President and Chief Banking Officer. INCOME STATEMENT PERFORMANCE In the second quarter, revenue (net interest income plus non-interest income) grew to $15.2 million, contributing to a year-to-date figure of $29.4 million. Revenue for the second quarter 2005 was $13.1 million, with a year- to-date figure of $25.0 million. "As the Federal Reserve Board of Governors continues increasing interest rates, we benefit from assets re-pricing more quickly than deposits," said Greg Spear, Executive Vice President and Chief Financial Officer. "During the last several years we have positioned our balance sheet to be asset sensitive, meaning that the assets re-price, or adjust to market interest rates, more frequently than the liabilities." Net interest income before the provision for loan losses set another high mark by growing to $12.8 million, an increase of 27% over last year's second quarter total of $10.1 million. The year-to-date net interest income figure also increased markedly, to $24.7 million at June 30, 2006, up from $19.7 million a year ago, a 25% increase. The tax equivalent net interest margin for the second quarter was 6.60%, another significant increase and well ahead of the 5.90% figure for the same period in 2005. Year-to-date net interest margin for 2006 was 6.49%, also well ahead of the 5.86% figure from the same period a year ago. "Our loan and deposit pricing strategy takes into account the seasonal growth patterns between deposits and loans," Spear said. "Therefore, we hold the same pricing discipline for deposits as we do loans, and utilize wholesale liabilities to fund interim gaps in the balance sheet." Non-interest income for the second quarter was $2.4 million, a decrease of 20% over last year's second quarter total of $3.0 million. This decrease is due to a one-time gain in the second quarter of 2005, from the sale of the Bank's mortgage servicing asset. On a pro forma basis, second quarter 2005 non-interest income would have been $2.4 million. Year-to-date figures for the end of the second quarters of 2006 and 2005 were $4.7 million and $5.3 million, respectively. Total non-interest expense was $8.1 million, a 16% increase over the second quarter 2005 figure of $7.0 million. Year-to-date, total non-interest expense was $15.9 million, up 17% from last year's figure of $13.5 million. Expense growth for the quarter is due mainly to increases in compensation and recent de novo branch expansion activity. The Bank's efficiency ratio for the second quarter was 53.60%, compared to 54.92% in the second quarter 2005. Year-to-date efficiency ratio at June 30, 2006 was 54.02%, compared to 54.15% a year ago. The efficiency ratio is an important measure of productivity in the banking industry and measures overhead costs as a percentage of total revenues. BALANCE SHEET PERFORMANCE Consistent with seasonal trends, the Company's loan portfolio grew at a strong pace in the second quarter, with $766.6 million in gross loans, a 22% increase over the $626.4 million total reported at mid-year 2005. Total assets as of June 30, 2006, were $952.8 million, a gain of 22% over the second quarter 2005 total of $778.9 million. The Bank experienced growth across all markets with significant contributions coming from its new markets in Yakima, Sunnyside and the Tri-Cities area of Washington. Total deposits at June 30, 2006 were $777.3 million, compared to $668.9 million at June 30, 2005, a gain of 16%. Some of the growth in the second quarter was supplemented with wholesale liabilities collected outside of our regional branch network. Brokered certificates of deposit accounted for $32.0 million in deposit growth. Shareholders' equity now stands at $83.4 million, or $8.43 per outstanding share at June 30, 2006, up from $71.8 million, or $7.32 per outstanding share, for the second quarter 2005. Tangible book value stands at $7.68 as of June 30, 2006, compared to $6.57 as of June 30, 2005. ASSET QUALITY Asset quality remains consistent with our FDIC peer group with assets between $500 million to $1 billion. Non-performing assets at June 30, 2006 were $3.1 million, or 0.32% of total assets, compared to an unusually low $394,000, or 0.05% of total assets, at June 30, 2005. Net charge-offs during the second quarter were $465,000, or 0.06% of gross loans, at June 30, 2006, compared to $218,000, or 0.03% of gross loans, during the second quarter 2005. Allowance for loan loss was $9.7 million, or 1.26% of gross loans, at June 30, 2006, compared to $8.7 million, or 1.39% of gross loans, at June 30, 2005.
