Pennsylvania CCB Proposes Rule Capping Grower-Processor and Dispensary Cross-Ownership at 25% for Non-Microbusiness Applicants (December 2025)

The Pennsylvania Cannabis Control Board published a proposed rule that would cap cross-ownership between grower-processor and dispensary licenses at 25% for applicants who do not qualify as microbusinesses, responding to legislative pressure to prevent vertical monopolization of the Commonwealth's newly authorized adult-use market.

Background

Pennsylvania's Medical Marijuana Act (MMA) historically permitted significant vertical integration, with many operators holding both grower-processor and dispensary licenses. As Pennsylvania moves toward adult-use legalization in 2026, the Cannabis Control Board (CCB) has proposed rules under 28 Pa. Code Ch. 1141 to limit vertical integration to prevent market concentration.

Proposed Rule Summary

The proposed rule would amend 28 Pa. Code § 1141.52 to add the following restriction:

No person or entity may hold, directly or indirectly through affiliated entities, an ownership interest of 25% or more in both a Grower-Processor License and a Dispensary License issued under the adult-use framework, unless: (a) the licensee qualifies as a Microbusiness under § 1141.10; or (b) the ownership was established prior to the effective date of this section under the Medical Marijuana Act.

Grandfather Provision

Existing MMA licensees who hold cross-category ownership above 25% at the time of the rule's effective date would be grandfathered for up to three years. After the grandfather period, they must divest to comply.

Comment Period

The CCB is accepting written comments on the proposed rule through January 31, 2026. Comments must be submitted via the CCB's online portal or mailed to:

Pennsylvania Cannabis Control Board Attn: Rulemaking Division 408 Finance Building Harrisburg, PA 17120

Strategic Implications

Pennsylvania operators holding dual grower-processor and dispensary licenses should model the impact of the 25% cross-ownership cap on their capitalization structures. M&A transactions targeting the Pennsylvania market should include contingent provisions tied to the final rule's effective date. The grandfather provision suggests that consolidation transactions completed before finalization may be advantaged.
