Overview

A class action lawsuit has been filed against Gartner, Inc. (“Gartner” or the “Company”) (NYSE : IT), certain of the Company’s senior executive officers (collectively, “Defendants”), alleging violations of the federal securities laws. The Gartner lawsuit is brought on behalf of all persons and entities who purchased or otherwise acquired Gartner securities between February 4, 2025, and February 2, 2026, inclusive (the “Class Period”). Investors have until May 18, 2026, to seek appointment as lead plaintiff of the Gartner class action lawsuit.

Gartner provides technology and business insights to its clientele through guidance, tools, conferences, and direct consulting. The Company operates through three segments: Business and Technology Insights, Conferences, and Consulting.  

The complaint alleges that Defendants made materially false and misleading statements regarding the Company’s contract value (“CV”) growth and revenue outlook, including within its Consulting segment. Throughout the Class Period, Defendants repeatedly assured investors that Gartner was positioned to achieve accelerating CV growth, targeting 12–16% growth in a “normal” macroeconomic environment, and downplayed the impact of macroeconomic pressures, including tariff-related headwinds and changes in customer spending behavior.

In truth, Gartner was experiencing deterioration in its growth trajectory. The Company allegedly lacked the ability to handle ongoing challenges in the industry, meet its consulting revenue targets, or maintain CV growth rates, as customer decision-making slowed, sales cycles lengthened, and macroeconomic pressures impacted demand.

The truth started to be revealed on August 5, 2025, when Defendants announced a surprising decline in Gartner’s CV growth rate, both when considering contracts with the federal government and when excluding them.

On this news, the price of Gartner’s common stock declined $92.78 per share, or 27.5%, from a closing market price of $336.71 per share on August 4, 2025, to close at $243.93 per share on August 5, 2025.

Then, on February 3, 2026, Gartner again announced a significant decline in its CV growth rate, which had faltered another 2% both including and excluding federal contracts, and disclosed a significant shortfall of its Consulting segment’s performance against the Company’s internal projections.

On this news, the price of Gartner’s common stock declined $42.24 per share, or nearly 21%, from a closing market price of $202.40 per share on February 2, 2026, to close at $160.16 per share on February 3, 2026.
