EXHIBIT 99.1 INDEPENDENT ACCOUNTANTS' REVIEW REPORT The Board of Directors and Audit Committee PrivateBancorp, Inc. We have reviewed the accompanying consolidated balance sheet of PrivateBancorp, Inc. as of March 31, 2004, and the related consolidated statements of income, changes in stockholders' equity and cash flows for the three month period ended March 31, 2004 and 2003. These financial statements are the responsibility of the Company's management. We conducted our reviews in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data, and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the United States, which will be performed for the full year with the objective of expressing an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion. Based on our reviews, we are not aware of any material modifications that should be made to the accompanying consolidated financial statements referred to above for them to be in conformity with accounting principles generally accepted in the United States. /s/ Ernst & Young LLP Chicago, Illinois May 7, 2004
