SCHEDULE
“A”


 


DIGIHOST TO COMMENCE TRADING ON NASDAQ ON MONDAY,
NOVEMBER 15


 


Toronto, ON – November 12, 2021 –
Digihost Technology Inc. (“Digihost” or the “Company”) (TSXV: DGHI; OTCQB: HSSHD), an innovative
North American-based Bitcoin self-mining company, today announced that the Company has been approved to list on the Nasdaq Capital Market
(“Nasdaq”), and that trading on Nasdaq is expected to begin on Monday, November 15, 2021, under the symbol “DGHI.”
The ticker used for Digihost’s shares traded over-the-counter (OTC) under the current symbol “HSSHD” will seamlessly
transition to the new ticker symbol “DGHI” on the first day of trading on Nasdaq. Digihost will also retain its listing on
the TSX Venture Exchange under the symbol “DGHI.”


 


The Company expects the Nasdaq listing to enhance
its investor profile and increase liquidity for its shareholders.


 


“A key goal of Digihost has been to provide
our investors with greater liquidity through the listing of our shares on a major United States stock exchange. We believe that uplisting
the Company’s shares from the OTC market to Nasdaq will also provide the Company with increased access to capital and institutional
recognition. We are excited about this significant milestone for the Company and our shareholders and look forward to continuing to implement
our growth strategy and building value for our shareholders,” commented Michel Amar, the Company’s CEO.


 


H.C. Wainwright & Co. served as advisor to
Digihost in connection with the Nasdaq listing, and Katten Muchin Rosenman LLP represented the Company as U.S. legal counsel in connection
with the Nasdaq listing. Peterson McVicar LLP serves as Canadian counsel to the Company.
