MORRISVILLE — Tobacco-leaf supplier Pyxus International Inc’s stock shot up 37 percent during trading Monday and then another 9 percent after-hours following a tweet by noted short-seller Citron Research.

As a result, the Morrisville company’s stock rose to $41.40 Monday, a total increase of $10.40.

Pyxus — previously known as Alliance One International — announced on Oct. 2 that its subsidiary, GoldLeaf Pharm, received a license to cultivate medical cannabis in Canada.

Citing a rush for cannabis stock, Citron Research tweeted that Pyxus’ value “could double from here as long as investors are Cannabis crazy.”

In recent months, Pyxus has expanded operations in the Canadian medical cannabis industry. In early September, an indirect subsidiary of Pyxus, Canada’s Island Garden Inc., received permission to sell medical cannabis oil.

The tweet also mentioned the hire of new executive vice president, Bryan Mazur, as proof that Pyxus was a good buy.

Mazur graduated with a bachelor’s in business from Baldwin-Wallace College and earned his MBA at Indiana University Bloomington. He has been at Dr. Pepper Snapple Group for 12 years, most recently serving as vice president and general manager.

Pyxus is primarily a tobacco leaf supplier for cigarette companies, but its subsidiaries also produce industrial hemp, e-liquids and soon medical cannabis. Formed in 2005 from the merger of DIMON Inc. and Standard Commercial Corp. the company has operations in over 90 countries.
