Alcanna Inc. CLIQ, -4.26% said Thursday that Canadian cannabis supply shortages worsened in the first quarter, getting worse as the reporting period went out. In the company's first-quarter conference call, Alcanna Chief Executive James Burns said that sales were strong but product was in short supply. "Our stores rarely if ever had saleable product on hand in inventory for the bulk of the week," Burns said. "The once a week delivery sold out often same day and almost always by the end of the weekend." Alcanna said that its five Nova stores recorded C$6.4 million in first-quarter sales. Burns said that after discussions with licensed cannabis producers and analyzing the public data, Alcanna estimates that supply shortages will ease "sometime towards the end of this year" and become "somewhat of an oversupply situation." Burns also said that he does not anticipate beverages or edibles to become a dominant part of the market upon legalization of such products in Canada. Vaporization products, on the other hand, will become a dominant "force in cannabis consuming" that will ultimately surpass bud or flower sales. Alcanna stock closed up 6.2% in Thursday trading, as the S&P 500 index SPX, +1.01% fell 0.3%.
