Law Offices of Howard G. Smith has announced four securities class actions involving Hyliion Holdings Corp., Hims & Hers Health, Inc., Unicycive Therapeutics, Inc., and Taboola.com Ltd. The cases cover alleged misleading statements and undisclosed adverse information about the companies’ businesses, operations, prospects, regulatory exposure, manufacturing oversight, or publisher relationships. Lead plaintiff deadlines are October 27, 2026, for Hyliion; October 30, 2026, for Taboola; and November 2, 2026, for both Hims & Hers and Unicycive. The complaints allege that Hyliion disclosed a deal with a recently formed entity lacking apparent business operations and that Individual Defendants timed the announcement to trade shares; that Hims & Hers shared consumers’ health information with third-party advertising platforms, charged for prescriptions soon after intake forms, and faced potential regulatory fees and penalties; that Unicycive had not audited a third-party manufacturer’s facility, creating risks involving FDA (U.S. drug regulator) requirements and delays to OLC approval; and that Taboola faced more low-quality publishers, requiring an aggressive exit strategy that affected earnings and overstated publisher-relationship value. Investors do not need to act to remain absent class members and may retain counsel of their choice. The firm provided contact details for Howard G. Smith, Esquire, and said the release may constitute Attorney Advertising in some jurisdictions.
