Increases Ownership from 70% to 100% in Illinois Cultivation Project

MEDFORD, Ore. , Sept. 22, 2025 /CNW/ - Grown Rogue International Inc. ("Grown Rogue" or the "Company") (CSE: GRIN) (OTC: GRUSF), a flower-forward cannabis company combining craft values with disciplined execution, today announced it has completed the acquisition of the 30% minority interest in Rogue EBC, LLC, its Illinois subsidiary. The total consideration is $1.5 million, with $500,000 paid at closing, $500,000 due in six months, and $500,000 due at the earlier of 15 months from closing or the date of the first harvest.

"We are pleased to have this consolidation complete, setting the stage for the development of our Illinois project to continue," said Obie Strickler, CEO of Grown Rogue.

Strickler continued, "When we first struck our partnership in Illinois, we were excited about managing the cultivation operations in partnership with an operator who would run the manufacturing operations. However, owing to a request for liquidity from our partner for reasons completely unrelated to Grown Rogue, we decided to opportunistically acquire 100% of this project. Increasing our ownership at an attractive price before we're operational is a logical step, supported by the success we've had in efficiently producing craft quality flower in multiple markets, most recently with our recent launch in New Jersey, which has a market structure that we believe resembles Illinois."

The deal is subject to final approval by the Illinois Department of Agriculture.
