Halper Sadeh LLC said Aug. 24, 2026, that it is investigating four additional proposed corporate transactions for potential violations of federal securities laws and/or breaches of fiduciary duties to shareholders. The matters involve Weave Communications, Inc.'s sale to Francisco Partners for $7.40 per share in cash; Fulcrum Therapeutics, Inc.'s merger with Slate Medicines, Inc., under which Fulcrum shareholders are expected to own 5.0% of the combined company; Iridium Communications Inc.'s sale to Rocket Lab Corporation for $27.00 in cash plus a number of Rocket Lab common shares determined by an exchange ratio; and Bio-Techne Corporation's sale to Merck KGaA for $73.00 per share in cash. The notice adds to seven transactions previously identified by the firm involving Cherry Hill Mortgage, Accelerant Holdings, Harte Hanks, Werewolf Therapeutics, Beazer Homes, MarketAxess and CBIZ. Halper Sadeh said insiders may receive benefits unavailable to ordinary shareholders and that deal terms may limit superior competing offers. It may seek increased consideration, additional disclosures and information, or other relief and benefits, while offering shareholders no-cost consultations and contingent-fee representation without upfront payment of legal fees or expenses.
