Massachusetts-based Curaleaf was fined $250,000 for failing to disclose a change of ownership structure related to its cannabis operations in the state.
The Cannabis Control Commission said Curaleaf made a mistake but had essentially acted in good faith, the news outlet reported.
The company has also faced problems over medical claims it has made about its CBD products.
Curaleaf trades on the CSE under the ticker symbol CURA.
