They report. Sundial Growers Inc. shares fell another 4.7% on Monday, after the Canadian cannabis company became the subject of a class-action lawsuit in the U.S. for allegedly failing to disclose that a customer returned half a ton of cannabis because it contained mold and bits of rubber gloves.

The allegations were first reported by MarketWatch’s Max A. Cherney On Aug. 20, and MarketWatch’s reporting is cited in the suit.

Sundial SNDL, -3.21%  went public on the Nasdaq on Aug. 1., selling 11 million shares priced at $13 each to raise $143 million. In its IPO documents, the company said it produces “high-quality, consistent cannabis.”

The Calgary, Alberta-based company reported earnings on Aug. 20, the same day that another Canadian cannabis company, Zenabis Global ZENA, +7.69%, disclosed that it had returned a half ton of pot and terminated its agreement to buy weed from a “third party” that it did not name.

People familiar with the matter said that party was Sundial, as MarketWatch reported, and Zenabis returned the cannabis because the pot was of poor quality and contained bits of rubber, among other issues. The batch was worth about C$2.5 million ($1.9 million) at the time.
