Organigram Announces Health Canada Licensing of Phase 3 Cultivation Expansion

Licensed production capacity expected to be 36,000 kg/yr by end of June 2018

TORONTO, June 5, 2018 /CNW/ - Organigram Holdings Inc. ("Organigram" or the "Company") (TSX VENTURE: OGI) (OTCQB: OGRMF) a leading licensed producer of medical marijuana based in Moncton, New Brunswick, is pleased to announce that it has received an expanded cultivation license from Health Canada related to its previously announced Phase 3 expansion.

The scope of the amendment includes approval of the following:

• The entire perimeter of the expanded facility, approximately 40,000 sq ft;
• The first six of Organigram's new 16 three-tier cultivation rooms in the Phase 3 expansion; and
• Refined functional design on an already improved Phase 2 design including slightly higher grow rooms and the location of HVAC units entirely on the outside of the rooms for enhanced ergonomics and improved airflow.

As a result of this approval, cannabis plants will be moved into these new rooms on a rolling basis beginning on June 6, 2018. The Company will be able to begin staggered harvests from these new rooms by the first week in August. The remaining ten Phase 3 rooms are expected to come online on or before June 30, 2018 in stages pending Health Canada approval.

Organigram is also pleased to note that this licensing does not require a new sales license and there will be no delay from harvest to sale.

Once the remaining Phase 3 rooms are online the Company will have a target production capacity of 36,000 kg/year of dried flower equivalent.

"Based on our review of publicly available data we believe we will be one of the top 5licensed producers in terms of current production capacity once the remaining rooms from Phase 3 are approved", said Greg Engel, CEO. "Given our existing inventory, production volume and consistency and quality of supply, we believe we are well positioned to be a supplier of choice for many of the provincial cannabis boards and private retailers across Canada."
