Curaleaf Bets Nearly $1 Billion on Weed Oil in Largest U.S. Deal

Curaleaf Holdings Inc., the most valuable U.S. marijuana company, is making a big bet on cannabis oil.

The Massachusetts-based company is buying the regulated cannabis business of Cura Partners Inc., a maker of oil for vape pens, in a stock deal valued at about $950 million. That makes it the largest acquisition so far between U.S. cannabis companies. Cura, based in Portland, Oregon, sells its Select brand marijuana products in more than 900 dispensaries, including in California, which is home to the world’s largest legal weed market. It had revenue of about $117 million last year.
