Item 4. Purpose of Transaction.

The Reporting Persons acquired the shares of Common Stock based on the Reporting Persons’ belief that the shares of Common Stock, when acquired, were undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons and the availability of shares of Common Stock at prices that would make the purchase or sale of shares of Common Stock desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of shares of Common Stock in the open market, private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the shares of Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons intend to continue to consider, explore and/or develop plans and may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with the Issuer’s management and the Board, engaging in discussions with shareholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capital allocation strategy, capitalization, ownership structure, strategic transactions, including business combinations, a sale of the Issuer as a whole or in parts or acquisitions or investments by the Issuer, Board structure (including Board composition), operations of the Issuer, purchasing additional shares of Common Stock, selling some or all of their shares of Common Stock, engaging in short selling of or any hedging or similar transaction with respect to the shares of Common Stock, or take any other actions with respect to their investment in the Issuer permitted by law, including any or all of the actions set forth in paragraphs (a)—(j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.

Wilks Brothers, LLC is a manager-managed limited liability company, managed by Dan Wilks and Farris Wilks. Dan Wilks and Farris Wilks are brothers and may be deemed to indirectly beneficially own the shares of Common Stock directly beneficially owned by Wilks Brothers.

Dan Wilks, together with his spouse, Staci Wilks, who share the same household, may be deemed to exercise voting and investment power over an additional 349 shares of Common Stock and therefore may be deemed to beneficially own such shares.
