INVESTIGATION ALERT: The Schall Law Firm Announces it is Investigating Claims Against ProPetro Holding Corp. and Encourages Investors with Losses in Excess of $100,000 to Contact the Firm

The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors in ProPetro Holding Corp. (ProPetro or the Company) (NYSE: PUMP) for potential breaches of fiduciary duty on the part of its directors due to allegations that ProPetro may have issued materially misleading business information to the investing public.

The investigation focuses on determining if ProPetros Board breached its fiduciary duties to shareholders. Specifically, following the securities lawsuit filed against the Company, Reuters reported the SEC had also opened an investigation. ProPetro revealed on November 13, 2019, that it had found another $3.6 million in related-party transactions. The investigation will determine if ProPetros board of directors breached its fiduciary duties to shareholders, grossly mismanaged ProPetro, and/or committed abuses of control as a result of the foregoing.
