Halper Sadeh LLC said it is investigating three proposed transactions for potential violations of federal securities laws and breaches of fiduciary duties to shareholders. The matters involve Fulcrum Therapeutics’ merger with Slate Medicines, TriCo Bancshares’ sale to First Hawaiian, and LXP Industrial Trust’s sale to Brookfield Asset Management and Canada Pension Plan Investment Board. The firm said insiders may receive financial benefits unavailable to ordinary shareholders and that deal terms may restrict superior competing offers. It may seek increased consideration, additional disclosures and information, or other relief for shareholders. Shareholders can contact the firm at no cost or obligation, with legal fees and expenses handled on a contingent-fee basis.
