Gartner Investors Urged to Seek Lead Role in Securities Suit Before May 18 Deadline

Overview

• New notices this week urge pension funds and asset managers to evaluate serving as lead plaintiff before the May 18, 2026 deadline.
• The lawsuit alleges Gartner overstated growth in contract value and presented an overly positive outlook for its Consulting segment, which investors say kept the share price inflated.
• Contract value means the yearly value of active research subscriptions, and plaintiffs claim slowing growth undercut future revenue expectations during the Feb. 4, 2025 to Feb. 2, 2026 class period.
• Filings point to two updates that they call corrective disclosures, which lined up with sharp single-day drops of 27.55% on Aug. 5, 2025 and 20.87% on Feb. 3, 2026, and a peak-to-trough slide of more than 52%.
• Lead plaintiffs would oversee the case and select counsel, while the action proceeds under Sections 10(b) and 20(a) and SEC Rule 10b-5 with allegations that remain unproven.
