CISCO, Texas, Sept. 11, 2020 /PRNewswire/ - Wilks Brothers, LLC ("Wilks") is pleased to announce that proxy advisory firm Glass Lewis & Co. ("Glass Lewis") has today reversed its original voting recommendation and now recommends, that Shareholders of Calfrac Well Services Ltd. ("Calfrac") (TSX: CFW)  vote AGAINST Calfrac's Recapitalization Transaction (the "Management Transaction") at the special meeting of Shareholders to be held on September 17, 2020 (the "Meeting").

Glass Lewis makes the following compelling points, considering both the Wilks "Superior Alternative Proposal" and the Wilks' premium take-over bid which was launched on September 9, 2020 (the "Premium Offer") in contrast to the conflict-ridden Management Transaction, in recommending that Shareholders now vote AGAINST the Management Transaction and all other items at the Meeting:

"In light of the formal launch of the Wilks Offer … and the Company's announcement … that the Calfrac special committee and board will review the Wilks Offer, file a circular and make a recommendation to shareholders with respect to the Wilks Offer in due course, at this time, in order to preserve the ability of shareholders to potentially tender into and accept the Wilks Offer, we believe unaffiliated Calfrac shareholders should vote against the Recapitalization Transaction currently proposed by the board and management. As noted above, the Wilks Offer is not available if the Recapitalization Transaction proceeds". (emphasis added)

"In terms of the common shareholder value differential, as noted in Wilks' announcements, the Wilks Offer price of C$0.18 per share represents a 20% premium to Calfrac's share price on September 1, 2020, the last trading day before Wilks announced its intention to make a takeover offer. Wilks also asserts that the Wilks Offer price is far superior to the C$0.03 per share that common shareholders would receive under the management-proposed Recapitalization Transaction. Wilks arrives at this estimated value under the Recapitalization Transaction based on the Company's disclosure in the July 13, 2020 announcement presentation of a C$50 million plan equity value, a pro forma share ownership for existing shareholders of 7.8% and 1,877 million total common shares outstanding (pre-dilution). From the perspective of common shareholders, we recognize that the choice between these two values is clear".

"Given the current financial position and prospective performance of Calfrac going forward, we are inclined to suggest that an immediate, all-cash payment at a price representing a premium to Calfrac's unaffected and current share prices -- and a value that is roughly six times greater than the estimated initial value under the Recapitalization Transaction -- may reasonably represent a superior alternative for Calfrac's common shareholders, especially when considering the risk and uncertainty inherent in the Company's business plan and the Recapitalization Transaction". (emphasis added)

"… now that the Wilks Offer has been formally launched and is pending review by the Calfrac board and special committee, given the nearness of the upcoming voting deadline for the Recapitalization Transaction currently proposed by the board, in order for shareholders to preserve full optionality at this time, we believe shareholders should vote against the Recapitalization Transaction and all other proposals at the EGM".

This revised Glass Lewis recommendation follows the recommendation of another leading independent proxy advisory firm, ISS, that Wilks' Superior Alternative Proposal, backstopped by the Premium Offer, is in the best interests of Shareholders:

"Given that Wilks' debt reduction plan offers superior value to shareholders and its premium takeover bid mitigates the risk associated with renewed debtholder negotiations, shareholders are advised to use the dissident (blue) proxy card to vote AGAINST management's proposed Recapitalization Transaction". – Institutional Shareholder Services Inc. ("ISS"), September 5, 2020

Shareholders have a very clear choice:

•  Vote AGAINST the Management Transaction and preserve the right to benefit from the premium recovery of $0.18 per Calfrac Share under Wilks' Premium Offer

OR

• Support the Management Transaction and receive $0.03 per Calfrac Share in new stock under the Management Transaction¹, such stock may ultimately be wiped out due to the excessive debt leverage, including additional secured debt, resulting from the Management Transaction;

Your vote is necessary to STOP the Management Transaction. Vote BLUE Today.

Shareholders can only preserve their right to benefit from the premium recovery under the Premium Offer by first defeating the Shareholder vote on the Management Transaction. Shareholders should vote BLUE and AGAINST the Management Transaction.

The proxy deadline for the BLUE proxy is September 14, 2020 at 5pm MST. Click here for voting instructions.

If you have already voted AGAINST the Management Transaction using the BLUE proxy, you do not need to do anything further and we thank you for your support.

If you have yet to vote or want to change your vote, you are encouraged to vote using only the BLUE proxy. Please disregard any other proxies you receive. If you have already submitted a proxy solicited by Management, you may still change your vote and protect your economic interests by voting your BLUE proxy today. The later dated proxy will supersede any earlier proxy submitted.
