Securities Fraud Lawsuit Filed Against Taboola Over Alleged Misstatements on Publisher Quality
A securities fraud class action lawsuit has been filed against Taboola.com Ltd. (NASDAQ: TBLA) in the United States District Court for the Southern District of New York, according to an announcement from Glancy Prongay Wolke & Rotter LLP on August 21, 2026. The lawsuit, captioned Fortin v. Taboola.com Ltd. et al., Case No. 26-cv-07170, alleges violations of federal securities laws during the period from May 6, 2026 through August 4, 2026.
Founded in 2007 by Adam Singolda, who continues to serve as CEO, Taboola operates an AI-based content recommendation platform headquartered in New York City. The company partners with approximately 12,000 digital publisher properties, reaching roughly 600 million users per day to recommend editorial content and advertisements on the open web. Taboola went public on Nasdaq in 2021 through a SPAC transaction and reported 2024 full-year revenues of $1.77 billion with approximately 2,000 employees.
Revenue Miss Triggers Stock Decline
On August 5, 2026, Taboola reported second quarter 2026 earnings that fell significantly short of expectations. The company posted revenue of $476.8 million, missing its previously issued guidance range of $492 million to $505 million. The announcement triggered a sharp decline in Taboola's stock price, which fell $1.45, or 27.41%, to close at $3.84 on August 5, 2026, on unusually heavy trading volume.
Alongside the earnings miss, Taboola lowered its full-year 2026 outlook substantially. The company reduced expected revenue by $91 million at the midpoint to a range of $1.93 billion to $1.956 billion and lowered expected gross profit by $10 million at the midpoint to a range of $605 million to $615 million.
Publisher Quality Issues Cited
During the earnings call, company management explained that revenue fell below guidance in part because Taboola took a more aggressive approach in the second quarter by exiting publisher relationships that did not meet our standards for advertiser success.
The lawsuit alleges that between May 6, 2026 and August 4, 2026, defendants made materially false and misleading statements and failed to disclose material adverse facts about the company's business operations. Specifically, the complaint claims defendants failed to disclose that the company was experiencing an increase in low-quality publishers, that Taboola would need to aggressively exit these publisher relationships impacting earnings, that the value of the company's publisher relationships was overstated, and that positive statements about the company's business and prospects were materially misleading or lacked reasonable basis.
The significance of publisher relationships to Taboola's financial performance is underscored by the company's business model, which relies on a revenue-sharing arrangement where approximately 65% of gross revenue is paid out as Traffic Acquisition Costs to publishers, with about 35% retained as net revenue.
Additional Financial Headwinds
The earnings report also revealed that Taboola recorded a one-time non-cash writedown of approximately $12 million in Q2 2026 related to publisher prepayments that are no longer expected to be recouped. Additionally, a Google policy change that deprecated Taboola's 'Explore More' product is expected to result in a loss of over $20 million in ex-TAC gross profit in the second half of 2026.
These challenges come amid a broader deceleration in Taboola's revenue growth, which slowed from 22.7% in 2024 to 8.3% in 2025 and just 1.6% in 2026, according to earnings reports.
Legal Claims and Investor Rights
The lawsuit pursues claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. Under the Private Securities Litigation Reform Act of 1995, investors have 60 days from the date of public notice to file a motion to be appointed as lead plaintiff in the class action. Courts typically appoint the investor or group with the largest financial interest in the case to serve as lead plaintiff.
Investors who purchased Taboola securities during the class period and wish to serve as lead plaintiff must move the Court no later than 60 days from August 21, 2026. Those who take no action will remain absent members of the class.
