MedMen Enterprises Inc. announced Thursday a deal to sell a "significant portion" of its real estate assets to Treehouse Real Estate Investment Trust, with the initial deal expected to generate about $12.5 million in proceeds after the repayment of debt. Additional properties are expected to be sold to Treehouse over the next 12 months. The properties sold to Treehouse will be leased back to MedMen, a U.S.-based cannabis company.
