The New York-based firm is questioning the fairness of several high-profile deals, alleging that insiders may be positioned to receive benefits not extended to ordinary shareholders. The investigations target the $124.00-per-share cash sale of Nuvalent to GSK plc and the acquisition of Roku by Fox Corporation, which involves a mix of $96.00 in cash and 0.9693 shares of Fox Class A stock.

Additional probes concern the $7.40-per-share cash deal for Payoneer Global by Nuvei and the all-stock transaction involving Huntsman Corporation, which is set to be acquired by Olin Corporation at a ratio of 0.5476 Olin shares for each Huntsman share. Halper Sadeh is currently reviewing these terms to determine if shareholders are being shortchanged, noting that legal intervention could be used to seek increased consideration or more transparent disclosures regarding the underlying deal structures.
