Company Posts Record Profits and Revenues

CHICAGO, May 9, 2006 - Click Commerce, Inc. (Nasdaq: CKCM), a leading provider of on-demand supply chain management solutions, today announced record results for its first quarter ended March 31, 2006.

Total first quarter 2006 revenues were $19.7 million, representing over 80% growth from first quarter 2005 revenues of $10.9 million. On a fully-taxed non-GAAP basis, excluding certain charges as described below, net income was $4.3 million, or $0.33 per share on a diluted basis. This represents an improvement of approximately $2.3 million over Q1 2005’s non-GAAP net income of $2.1 million, or $0.18 per share on a diluted basis. On a GAAP basis, net income was $2.9 million, or $0.22 per share for the quarter ended March 31, 2006 compared to $2.6 million, or $0.23 per share for the quarter ended March 31, 2005. The Company’s first quarter results represent its eleventh consecutive profitable quarter, with a non-GAAP net income margin of 22% in the first quarter. Non-GAAP basis adjustments comprise non-cash charges related to the amortization of intangible assets and stock-based compensation, net of related income taxes and the addition of a 41% effective tax rate, applied to the first quarter of 2005.

The Company’s cash and cash equivalents were $22.3 million as of March 31, 2006 compared to $17.5 million as of December 31, 2005. The increase of $4.8 million primarily related to cash flows from operations of $8.2 million and proceeds from exercise of stock options of $1.3 million offset by $3.6 million of cash used in the February 2006 acquisition of the On-Demand Services and Contractor Management Software Business from Elance, Inc. (“Elance”). First quarter days sales outstanding were 101 days as compared to fourth quarter 2005 days sales outstanding of 111 days. Deferred revenue was $15.6 million as of March 31, 2006.

“This is Click Commerce’s best quarter ever. The improved year-over-year results reflect our focus on responsible growth and the successful integration of our acquisitions,” said Michael W. Ferro, Jr., chairman and CEO of Click Commerce. “These efforts continue to add to our top-line growth as well as our bottom-line performance.”

Today, the Company also announced that it has elected David Arney as the Company’s new Chief Financial Officer (“CFO”), effective May 8, 2006. Mr. Arney, with over 20 years of experience as a finance professional, will become the Company’s new CFO, replacing Mike Nelson, who is assuming a new position managing the Company’s M&A efforts and other strategic initiatives. Prior to being named the CFO, Mr. Arney held senior-level financial positions at various technology and business-to-business companies, including Q Interactive, Inc., formerly known as CoolSavings, Inc., where he was CFO from 2001 to 2006. Before that, Mr. Arney held various financial leadership positions at eLoyalty and Trans Union Corporation. Mr. Arney is a CPA and holds an MBA from Northwestern University’s J.J. Kellogg Graduate School of Management.

Conference Call

The Company will hold a conference call to discuss the results today, May 9th, at 9:00 a.m. (EDT), with remarks from Chairman and CEO Michael W. Ferro, Jr. and Michael W. Nelson. David Arney and Nancy Koenig, EVP of Operations, will be joining the call for Q&A. The call will also be broadcast live over the Internet.

Information Concerning Forward-Looking Statements

Information contained in this release that are not historical facts and refer to the Company’s future operations are forward-looking statements under the Private Securities Litigation Reform Act of 1995. Such statements involve expectations, estimates, assumptions, beliefs, hopes, plans or strategies regarding the future. These statements are subject to risks and

uncertainties and actual results may differ materially from those indicated by these forward-looking statements. Factors which could cause or contribute to such differences include, but are not limited to: the ability of the Company to integrate acquisitions or investments in other companies, the extent of customer acceptance and utilization of channel management products and services, the impact of competitive products and services, the volume and timing of customer contracts, changes in technology, deployment delays or errors associated with Click Commerce products and the ability to protect Click Commerce’s intellectual property rights. We refer you to the risk factors listed in our annual report on Form 10-K for the year ended December 31, 2005, quarterly reports on Form 10-Q and other filings, which are on file with the Securities and Exchange Commission. The Company expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement contained herein to reflect any change in the Company’s expectations with regard thereto or to reflect any change in any event, condition or circumstance on which such forward-looking statement is based, in whole or in part.

Non-GAAP Financial Measures

The non-GAAP financial measures contained in this earnings press release exclude amortization of intangible assets and an adjustment to present the prior year net income as if such results had been fully taxed. The Company uses these measures for planning and forecasting its future business as well as analyzing such forecasts against past performance. In addition, excluding these charges and including prior year tax expense enhances the Company’s understanding of trends developing in its operations as well as its performance in its market and against its competitors. The Company believes that providing specific financial information on the cost of such expenses, as well as providing non-GAAP net income measures that exclude such items, best allows investors to understand the Company’s ongoing business activities during the quarter. The Company believes that inclusion of certain non-GAAP financial measures provides comparability to similar companies in the Company’s industry, many of which present similar non-GAAP financial measures to investors. The non-GAAP financial measures should not be considered as a substitute for, or preferable to, measures of financial performance prepared in accordance with GAAP and may be different from non-GAAP financial measures used by others.

The Company believes that these non-GAAP financial measures provide an additional tool for investors to evaluate its ongoing operating results and trends. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures as detailed below (in thousands, except earnings per share and margins):
