To Our shareholders 2004 was a good year for Columbia Bank as we reached the milestone of $2 billion in assets and reported record profits. The improving economy and our strong branch network supported our growth in loans, deposits and credit quality. Through expanded customer relationships, we continued to leverage our broad base of branches, building greater market share. We increased value to the Company with a successful acquisition and new additions to our staff that provided significant contributions to our bottom line. In October 1, 2004 the acquisition of Bank of Astoria brought $170 million in assets, and most importantly, its very capable staff who share our culture and attitude about providing exceptional customer service. The bank is headquartered in Astoria, Oregon and has five branches, located in Astoria, Warrenton, Seaside, Cannon Beach and Manzanita. Led by Cheri Folk, President and Chief Executive Officer, Bank of Astoria is a high-performing organization, with 34% market share in Clatsop County. Bank of Astoria will continue to operate under its existing name and locations, with the same management and local board of directors. Melanie Dressell and Cheri Folk We are pleased to report record profits for the year 2004, the result of increased interest income, loan growth, rising short-term interest rates and our ongoing commitment to providing excellent service to our customers. Net income for 2004 was $22.5 million compared with $19.5 million in 2003, an increase of 15%. On a diluted per-share basis, net income for the year was $1.52, up 11% from $1.37 in 2003. Another important highlight for the year was our loan growth. Compared to 2003, our outstanding loans grew $281 million, up 26% to $1.4 billion at the end of 2004. Our 4th quarter showed the most loan growth, increasing over $194 million from the end of the 3rd quarter 2004. This increase is system wide. While the Bank of Astoria portfolio added over $100 million in loans, we generated the remainder through our loan production staff throughout our market areas. Our lenders stepped up their emphasis on calling on potential and current customers, and continued to provide the exceptional service for which we are known. These efforts have been rewarded with not only new relationships moving to Columbia Bank, but also expansion of existing relationships. We also expanded our King County team in 2004. We added nine experienced bankers who were formerly with Washington Mutual, which discontinued its business banking operation. These bankers had many other opportunities, but chose to come to Columbia Bank, and are making significant contributions to our loan portfolio. Our merchant services area is another of our success stories. The group continues to grow its fee income, which was $7.3 million for 2004, up 19% from 2003. In addition to healthy loan growth, we experienced improving trends in almost all of our nonperforming asset classes. In June of 2004, we welcomed Andy McDonald to our executive team as EVP and Chief Credit Officer. Andy has continued our efforts to improve our credit quality; in fact, we are seeing some of our strongest credit quality statistics. Our nonperforming loans to period-end loans ratio was 0.62%, nonperforming assets to period-end assets was 0.42% and our allowance for loan losses to nonperforming loans was 235% at December 31, 2004. While we have focused the last couple of years on maximizing the potential of our branch network and focusing on the strong base we have built in our current market area, we will always consider strategic new markets and branch locations. We will extend our footprint early this year by adding a branch in University Place, which is a thriving community just west of Tacoma, and will bring Columbia Bank’s total network to 35 branches in 5 counties. We continue to see progress in our objective of increased market share. In 2003, Columbia Bank was number 1 in deposits among commercial banks in Pierce County, and in 2004 we reached almost 18% share of the market. Our retail network is strong, with several branches having over $100 million in deposits, and yet there is plenty of room to grow—we believe we haven’t reached capacity in any of our markets. In summary, Columbia Bank had a good year. The seamless integration of Bank of Astoria, as well as the significant expansion in our lending staff in King County were certainly highlights of our year, and demonstrate our commitment to the strategy of quality growth. Our improved profitability reflects the success of our strategy to provide excellent service to our retail and commercial customers. Of course, this wouldn’t be possible without the efforts of our wonderful staff, who strive to exceed the expectations of our customers each and every day. As always, we will continue to emphasize our strong commitment to the hundreds of community activities we support not only financially, but also by volunteering our time. Although we will continue to grow, our strategy and heartfelt desire is to be the community bank in all the communities we serve. William T. Weyerhaeuser Melanie J. Dressel
