Viston United Swiss AG Withdraws Offer to Acquire Petroteq Energy Inc.

Viston United Swiss AG (“Viston”) and its indirect, wholly-owned subsidiary, 2869889 Ontario Inc. (the “Offeror”) today announced that the Offeror’s all-cash offer (the “Offer”) to acquire all of the issued and outstanding common shares (“Common Shares”) of Petroteq Energy Inc. (“Petroteq”) (TSX-V: PQE; OTC: PQEFF; FSE: PQCF) has been withdrawn.

Viston and the Offeror have withdrawn the Offer following an evaluation of recent developments in connection with the Offer, including, without limitation, the rejection by the Committee on Foreign Investment in the United States of the joint voluntary notice submitted by the Offeror and Petroteq in connection with the Offer. As a result of such developments, Viston and the Offeror concluded that several conditions to the Offer (as restated in the Offeror’s Fifth Notice of Extension dated July 22, 2022 under the heading “Conditions of the Offer”) are incapable of being satisfied or are likely to be unsatisfied as of the scheduled Expiry Time of 5:00 p.m. (Toronto time) on September 9, 2022.

Petroteq shareholders that have tendered their Common Shares to the Offer will have their Common Shares returned by the Depositary, Kingsdale Advisors (“Kingsdale”), in accordance with the procedures set out in the Offer. Deposited Common Shares will be returned to the depositing Shareholder as soon as practicable, by either (i) Kingsdale sending certificates representing the Common Shares by first-class insured mail to the address of the depositing Shareholder specified in the Letter of Transmittal or, if such name or address is not so specified, in such name and to such address as shown on the securities register maintained by or on behalf of Petroteq, or (ii) in the case of Common Shares deposited by book-entry transfer of such Common Shares, by Kingsdale arranging for such Common Shares to be credited to the depositing holder’s account maintained with intermediaries at CDS or DTC, as applicable. Shareholders with questions may contact Kingsdale at the contact details listed below.
