The Reverse Stock Split will become effective on December 11, 2019 (the "Effective Date"), pursuant to approval from the Financial Industry Regulatory Authority ("FINRA")... On the Effective Date, the Company's trading symbol will change to "CLSKD" for a period of 20 business days, after which the "D" will be removed from the Company's trading symbol, and thus, the Company's trading symbol will revert to the original symbol of "CLSK".”
