Shares of Moncton-based cannabis producer Organigram plunged on the Toronto Stock Exchange on Tuesday after the company unexpectedly issued preliminary fourth-quarter results a day earlier. The company now says it will report $16.3 million in net revenue for the quarter ended Aug. 31, down from $24.8 million in its prior quarter. The lower revenue is also expected to result in negative adjusted EBITDA (earnings before interest, tax, depreciation and amortization), ending a stretch of three consecutive periods of positive cash flow. Organigram attributes the decline in sales to a sluggish national retail rollout, specifically the “slower than expected store openings in Ontario” as well as “increased industry supply”. Jefferies analyst Owen Bennett says the fears of oversupply or price compression in the industry are “likely overdone” and remains bullish on Organigram’s prospects despite the “disappointing” update. The company will report its full results for its financial year on Nov. 25.
