Item 9. Regulation FD Disclosure ------------------------ On November 13, 2000 we conducted a conference call related to our financial guidance for the fiscal year ending July 31, 2001. We are furnishing the following information in response to questions received after the conference call. We do not intend to update this information, unless we believe that it is necessary to do so in accordance with Regulation FD. Q: What were CMGI's holdings of publicly traded stock at October 31, 2000? A: Please see Table 1. ------- Q: What were CMGI's holdings of publicly traded stock at July 31, 2000? A: Please see Table 2. ------- Q: Can you help us understand how/why CMGI's stock holdings are designated as "available-for-sale" in its consolidated balance sheet and why these stock holdings are "carved out" from the total pool of public securities held by the company? A: The classification of certain of our publicly traded stock holdings as "available-for-sale securities" in our consolidated balance sheet is governed by Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" (SFAS No. 115). Our holdings in publicly traded stock for which our ownership interest in the underlying company is greater than 20%, or for which it is determined that we can exercise significant influence over the underlying company, do not meet the criteria for classification as 2

"available-for-sale securities" under SFAS No. 115. These investments are accounted for on either the consolidation or equity method of accounting in our consolidated financial statements. In addition, certain of our holdings in publicly traded stocks are subject to various contractual lock-up agreements. If a marketable security carries restrictions on transferability for a period of greater than one year, the security does not meet the criteria for classification as "available-for-sale securities" under SFAS No. 115. Q: CMGI disclosed on the conference call that subsequent to July 31, 2000 AdForce was transitioned from the Interactive Marketing segment to the Infratructure segment and that Signatures Network would be transitioned from the Search & Portals segment to the e-Business and Fulfillment segment. Further, as a result of these reporting changes, results for the fiscal fourth quarter of the year ended July 31, 2000 would be reclassified. What are the fourth quarter results taking into account these reclassification(s)? What are the third quarter results, taking into account these reclassification(s)? A: Please see Table 3. ------- 3
