This Amendment No. 1 on Form 10-Q/A is being filed by Gartner, Inc. (the "Company") solely to correct a typographical error included in the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2015, which was filed with the Securities & Exchange Commission on November 5, 2015 (the “Original Form 10-Q”).

The Company incorrectly included the word "almost" in the second paragraph of the Research segment results discussion on page 30 in the Original Form 10-Q in the following sentence: "Contract value increased by double-digits across all of the Company's sales regions and client sizes and almost all industry sectors."

In fact, the Company's contract value increased by double-digits across all of its industry sectors. As a result, the Company is amending it's Original Form 10-Q and replacing that sentence with the following: "Contract value increased at double-digit rates (adjusted for the impact of foreign currency) across all of the Company's sales regions, client sizes, and industry sectors."

Items included in the Original Form 10-Q that are not amended by this Form 10-Q/A remain in effect as of the date of the Original Form 10-Q.
