Initial Yields Support Predictions of Increased Capacity in Production Facility Expansion

MONCTON, NB, April 23, 2018 /CNW/ - Organigram Holdings Inc. (TSX VENTURE:OGI) (OTCQB:OGRMF) (the "Company" or "Organigram"), a leading licensed producer of medical marijuana based in Moncton, New Brunswick, is pleased to announce the yield results from the inaugural harvest in the first of its 23 new, state-of-the-art Phase 2 indoor grow rooms.

Beginning on Friday, "4/20" and completed on Saturday, Organigram harvested over 1500 plants from the first room commissioned in the Company's Phase 2 expansion. The first of the 23 new rooms, which began housing plants on February 10th, has reached final stages of flowering for its first crops. Harvests from subsequent rooms will begin this week.

Initial yields support the Company's predictions that changes in process efficiencies will result in annual yields higher than initially estimated when Phase 2 was designed.  At present, the Company reaffirms its target production capacity from Phases 1 and 2 of approximately 22,000 kg/year (up from initial estimations of 16,000 kg/year). Facility enhancements include a fully-automated irrigation system, automated potting, a fully automated waste destruction system and automated packaging lines, adding to a data-based production approach which ensures growing optimization for every room.

"The first harvest out of these new rooms is proof that we've come to know our plant strains and our tools to the point where we understand how to create the optimal environments they need in order to thrive," says Organigram CEO Greg Engel, adding Organigram targets yields of approximately 400 grams per square foot of canopy space.

Another 16 growing rooms are anticipated to be brought online with plants beginning to fill the rooms on or around June 1, 2018, following Health Canada approval of its Phase 3 expansion. Once approved, this subsequent addition will result in a target combined production capacity from Phases 1, 2 and 3 of 36,000 kg/year.
