ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS. (c) Exhibits EXHIBIT NO. DESCRIPTION - --------------- ------------------------------------------------------------- 99.1 Press Release issued April 29, 2004, with respect to: -- Financial results for Gartner, Inc. (the "Company") for the quarter ended March 31, 2004; and -- The announcement that Michael Fleisher, Chairman and CEO, intends to leave the Company. ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION. On April 29, 2004, Gartner, Inc. announced financial results for the quarter ended March 31, 2004. A copy of the Company's press release is furnished herewith as Exhibit 99.1 and is incorporated herein by reference. The information contained in this report shall not be incorporated by reference into any filing of Gartner, Inc. with the SEC, whether made before or after the date hereof, regardless of any general incorporation language in such filings. The press release issued by the Company and furnished herewith as Exhibit 99.1 contains a non-GAAP financial measure. For purposes of the Securities and Exchange Commission's Regulation G, a non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with accounting principles generally accepted in the United States ("GAAP"). In the attached press release, Gartner, Inc. uses the non-GAAP measure of normalized EPS. This non-GAAP financial measure is provided to enhance the reader's overall understanding of Gartner's current financial performance and prospects for the future. Gartner believes normalized EPS is an important measure of Gartner's recurring operations as it excludes items that may not be indicative of our core operating results. These measures however should be considered in addition to and not as a substitute for, or superior to other measures of financial performance prepared in accordance with GAAP. Normalized EPS is based on net income (loss), excluding other charges, income from investments, goodwill impairment and other non-cash charges. Normalized EPS for 2003 also includes the effect of the convertible debt as if it had been converted at the beginning of 2003. In the attached press release, a reconciliation of normalized net income and normalized EPS to GAAP net income (loss) and GAAP net income (loss) per share is provided under "Supplemental Information" at the end of the release.

SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized. GARTNER, Inc. Date: April 29, 2004 By: /s/ Christopher Lafond --------------------------- Christopher Lafond Executive Vice President, Chief Financial Officer
