Schall Law Firm Reminds Investors of Class Action Lawsuit Against ZoomInfo Technologies Inc.

ZoomInfo Technologies Inc. (NASDAQ: GTM) is facing a major securities fraud class action lawsuit after its stock crashed 33% in a single day on May 12, 2026, according to The Schall Law Firm. The collapse came after the company slashed its full-year revenue guidance by $62 million and announced a 20% cut to its global workforce.
Investors who bought GTM shares between November 3, 2025, and May 11, 2026, have until August 24, 2026, to apply to lead the lawsuit, per AP News. Multiple shareholder rights firms — including The Schall Law Firm and Levi & Korsinsky, LLP — are now organizing affected investors.
On May 11, 2026, ZoomInfo reported its Q1 2026 results after market close. The news was grim. The company cut its full-year revenue target to roughly $1.185–$1.205 billion — down from the original $1.247–$1.267 billion it had promised investors, according to Bronstein, Gewirtz & Grossman. That same day, it announced layoffs equal to 20% of its entire workforce.
The market reacted fast and hard. Shares fell from $6.04 to $4.06 — a drop of 33% in one session — according to Levi & Korsinsky. That single-day loss wiped out hundreds of millions in market value. The stock has now fallen 97% from its November 2021 peak.
The lawsuit, filed June 26, 2026 as Tejada v. ZoomInfo Technologies Inc. in the U.S. District Court for the Western District of Washington, names CEO Henry Schuck and CFO M. Graham O'Brien as defendants. Plaintiffs say both executives knew demand was weakening but kept telling investors the business was growing, according to Levi & Korsinsky.
The core claim is that customers were quietly moving away from ZoomInfo's seat-based subscription model. Many were building their own internal AI tools instead of buying ZoomInfo's software. Brian Schall said the company "led investors to believe it was enjoying growth" while demand was actually falling, according to The Schall Law Firm.
In May 2025, ZoomInfo changed its Nasdaq ticker from $ZI to $GTM, standing for "Go-To-Market." CEO Henry Schuck called it a signal of a platform built for a future "where go-to-market teams aren't stuck," per AP News. The stock jumped 7.4% that day on investor enthusiasm for the AI angle.
But plaintiffs argue the AI story was misleading. ZoomInfo promoted its "ZoomInfo Copilot" product and enterprise AI adoption — while internal data allegedly showed customers choosing cheaper, homegrown AI solutions instead. The company's own pivot to AI may have accelerated the erosion of its legacy business model, according to Bernstein Liebhard LLP.
The court deadline is firm. Investors must file to become Lead Plaintiff by August 24, 2026, according to The Schall Law Firm. The Lead Plaintiff role allows one investor — or a group — to direct the lawsuit strategy and represent all affected shareholders. The class has not yet been certified by the court.
Despite the legal chaos, ZoomInfo still generated $376 million in free cash flow over the past 12 months and holds 88% gross profit margins, per Stansberry Research. The company is now betting on an integration with OpenAI Codex to rebuild investor trust. Whether that is enough to stop the legal and market bleeding remains an open question.
