Halper Sadeh LLC said it is investigating Dominion Energy, Inc., NextEra Energy, Inc., and Arcosa, Inc. over proposed transactions that the firm said may raise issues under federal securities laws or shareholder fiduciary duty standards. The review covers Dominion's sale to NextEra in an all-stock deal valued at 0.8138 shares of NextEra for each Dominion share, NextEra's merger with Dominion under which NextEra shareholders are expected to own about 74.5% of the combined company, and Arcosa's sale to CRH for $150.00 per share. The firm said insiders may receive substantial financial benefits not available to ordinary shareholders and that the proposed transactions may include terms that could limit superior competing offers. Halper Sadeh said it may seek increased consideration, additional disclosures, or other relief on behalf of shareholders, and encouraged investors to contact the firm at no cost or obligation.
