Multiple investor-rights firms have announced or filed proposed securities class actions against Taboola.com Ltd. (NASDAQ: TBLA) on behalf of investors who purchased or acquired Taboola securities from May 6 through Aug. 4, 2026. The complaints allege Taboola failed to disclose a growing share of lower-quality publisher relationships, the earnings impact of aggressively ending those relationships, and that the value of its publisher network and business outlook were consequently overstated. On Aug. 5, 2026, Taboola reported second-quarter revenue of $476.8 million, below prior guidance of $492 million to $505 million, reduced full-year 2026 revenue guidance to $1,930 million to $1,956 million and gross-profit guidance to $605 million to $615 million, and said it had more aggressively exited publishers that did not meet advertiser-quality standards. Its shares fell $1.45, or 27.41%, to close at $3.84. Berger Montague, Gainey McKenna & Egleston, Rosen Law Firm, Bronstein, Gewirtz & Grossman, Schall, Brown & Schwartz LLP and Robbins LLP announced related Taboola matters. Lead-plaintiff motions are due by Oct. 20, 2026, and the proposed class had not been certified. Robbins's release contains an apparent clerical error referring in one participation section to Fractyl Health common stock rather than Taboola securities.
