Shares of Canadian cannabis producer Aphria Inc. and U.S.-based Green Growth Brands Inc. were halted by regulators late Tuesday. The Canadian regulator said the halt was due to pending news. Green Growth is in the midst of a hostile takeover bid of Aphria. Aphria executives said that Green Growth's public proposal undervalued the business, though the company has not received a formal bid from Green Growth. Aphria stock has been battered the last several weeks after a short seller report highlighted alleged issues with several of Aphria's acquisitions. Green Growth brands is backed by the powerful Schottenstein family. Aphria stock has fallen 40% in the past three months as ETFMG Alternative Harvest ETF dropped 9%.
