A securities class action has been filed against Taboola.com Ltd. on behalf of investors who purchased or otherwise acquired the company’s securities between May 6 and Aug. 4, 2026. Kirby McInerney LLP says investors have until Oct. 20, 2026, to seek appointment as lead plaintiff. The complaint alleges Taboola failed to disclose an increase in low-quality publishers, the need to exit relationships that did not meet standards for advertiser success, the resulting impact on earnings, and the alleged overstatement of publisher-relationship value. Taboola reported second-quarter 2026 revenue of $476.8 million, below guidance of $492 million to $505 million, and reduced full-year revenue guidance to $1.93 billion to $1.956 billion and gross profit guidance to $605 million to $615 million. Its shares fell $1.45, or 27.41%, to close at $3.84 on Aug. 5. Notices from Kirby McInerney, Glancy Prongay Wolke & Rotter, Kaplan Fox & Kilsheimer, and Levi & Korsinsky have identified the same Oct. 20 lead-plaintiff deadline, without establishing whether the firms represent the same proceeding or separate filings.
