LAS VEGAS, NV, February 28, 2019 

CLS Holdings USA Inc. (OTCQB:CLSH) (CSE:CLSH.U) “CLS”, a diversified cannabis company operating as Cannabis Life Sciences, has redeemed all of its convertible debentures issued to YA II PN, Ltd., “Yorkville”, a Cayman Island exempted limited partnership, which were issued on May 14, 2018 and July 20, 2018.

Pursuant to the terms of the debentures, the investor generally was able to convert any portion of the principal and accrued interest under the debentures into CLS Common Stock at a fixed conversion price of $0.40 per share. By redeeming the debentures for total cash consideration of $964,787, CLS has eliminated the potential issuance of approximately 2.5 million shares of CLS stock that would be immediately eligible for resale.

“We have been reviewing a number of options available to us for increasing shareholder value and felt this would be a beneficial transaction by eliminating the potential issuance of a substantial number of shares that could be sold in the market”.
