Halper Sadeh LLC announced investigations into four proposed transactions involving Centerspace, Iridium Communications, Colony Bankcorp and Standard BioTools, citing potential violations of federal securities laws and breaches of fiduciary duties to shareholders. Centerspace shareholders would receive 3.800 shares of Independence Realty Trust common stock per share; Iridium shareholders would receive $27.00 in cash plus Rocket Lab shares calculated under an exchange ratio. Standard BioTools shareholders are expected to own approximately 16% of the combined company with Treeline Biosciences, while financial terms for Colony Bankcorp's merger with First Reliance Bancshares were not provided. The firm said insiders may receive benefits unavailable to ordinary shareholders and that deal provisions could restrict superior competing offers. It may seek higher consideration, additional disclosures or other relief, and said matters would be handled on a contingent-fee basis without out-of-pocket legal fees or expenses. The announcement follows earlier investigations by Brodsky & Smith into Centerspace, Fulcrum Therapeutics, Weave Communications and Bio-Techne, and by Halper Sadeh into the latter three transactions.
