Yellowstoned Cannabis Co.'s lab license (operating as Yellowstoned Labs) has been deactivated in Montana, according to the state license roster updated September 9. The closure was among at least 12 cannabis-related licenses marked inactive the same day, spanning cultivation, retail, manufacturing, and lab operations across the state.

Montana's adult-use market currently counts 2 open labs, 538 retail locations, 302 cultivation sites, and 180 manufacturing facilities. August sales data shows the state moved approximately $28.9 million in cannabis product. The scope of September deactivations—including operations run by entities like Holistic Harvest, Big Mountain Botanicals, and Think Higher Caregiving—suggests a broader compliance or operational shift, though no stated reason was provided by the regulator.

Watch whether the state releases cause-of-closure details or compliance actions in coming weeks, and whether the active lab count stabilizes or declines further.
