Due Diligence Checklist for Acquiring a Cannabis License

Acquiring an existing cannabis business can be faster than winning a new license — but the license you are buying is only as good as its compliance history. Cannabis M&A due diligence goes well beyond the financial and legal review of a conventional deal.

Start with the license itself. Confirm the license type, its renewal status, any conditions imposed by the regulator, and — critically — whether and how it can be transferred. Many states require pre-approval of ownership changes, and some treat a sale as a new application. A deal signed without a viable transfer path is no deal at all.

Pull the compliance record. Request the target's full inspection history, notices of violation, settlement agreements, and any pending enforcement matters. In many states these records are obtainable from the regulator directly. Undisclosed violations can survive closing and become your problem.

Examine the ownership chain. Cannabis regulators hold buyers responsible for knowing exactly who has held interests in the license. Undisclosed owners, side agreements, or prior transfers that were never approved can jeopardize the license after closing.

Review the tax position with 280E in mind. Historical returns, COGS calculations, and any open IRS examinations deserve close scrutiny — tax liabilities follow the entity in a stock deal and can surface in an asset deal through successor liability theories.

Finally, verify the operational fundamentals: the real estate (lease term, zoning, landlord consent to assignment), key supplier and customer contracts, employee classification, and product liability exposure. Each of these can carry cannabis-specific wrinkles that generalist diligence misses.

A disciplined diligence process typically takes 60 to 90 days and pays for itself many times over. The worst time to discover a compliance problem is after the wire has gone out.
