Calfrac Prevails in Wilks Brothers U.S. Appeal and Provides Update on Legal Proceedings

CALGARY, AB, April 23, 2021 /CNW/ - Calfrac Well Services Ltd. ("Calfrac" or the "Company") (TSX: CFW) confirms that a hearing was held today, in the U.S. District Court for the Southern District of Texas, to consider the appeal brought by Wilks Brothers, LLC. This was Wilks Brothers' appeal of the order of the U.S. Bankruptcy Court for the Southern District of Texas which granted enforcement in the United States of Calfrac's Plan of Arrangement under the Canada Business Corporation Act.

At today's hearing, the District Court quickly affirmed the decision of the Bankruptcy Court, dispensing in full with Wilks Brothers' most recent attempt in the United States to derail Calfrac's already-completed Recapitalization Transaction.

In addition, Calfrac has received notice that Wilks Brothers has filed an application to the Ontario Securities Commission (the "OSC"), requesting a hearing and review by the OSC of the decision of the Toronto Stock Exchange granting exemptive relief in respect of the rescission of the purchase of 1.5 Lien Notes acquired by an institutional shareholder.

Calfrac believes that the TSX acted appropriately within its jurisdiction in granting exemptive relief, and that the application should be seen as a further attempt by Wilks Brothers to advance its self-interested business purposes.  Calfrac intends to oppose the application and will provide a further update upon any material developments.

Calfrac's common shares and warrants are publicly traded on the Toronto Stock Exchange under the trading symbols "CFW" and "CFW.WT", respectively. As a condition of TSX allowing the rescission of the purchase of a subscription of 1.5 Lien Notes acquired by an institutional shareholder as a corrective measure as further described in Calfrac's press releases of March 1, 12 and 29, 2021 and April 15, 2021, Calfrac will be subject to enhanced review by the TSX Compliance and Disclosure Group for the 12 months following such approval, subject to extension in the TSX's discretion.

Calfrac provides specialized oilfield services to exploration and production companies designed to increase the production of hydrocarbons from wells drilled throughout western Canada, the United States, Argentina and Russia.
