As previously disclosed, on June 16, 2019, C&J Energy Services, Inc. (C&J), Keane Group, Inc. (Keane) and
King Merger Sub Corp., a wholly owned subsidiary of Keane (Merger Sub), entered into an Agreement and Plan of Merger (as it may be amended from time to time, the Merger Agreement), pursuant to which they agreed to combine
their respective businesses in a merger of equals. Pursuant to the Merger Agreement, Merger Sub will merge with and into C&J, with C&J as the surviving corporation and wholly owned subsidiary of Keane (the Merger), and
immediately thereafter, as part of the same transaction, C&J will merge with and into another wholly owned subsidiary of Keane, with such subsidiary continuing as the surviving entity. On September 6, 2019, C&J filed with the Securities

meetings of C&Js stockholders and Keanes stockholders, each to be held on October 22, 2019, for purposes of voting, among other things, on maters necessary to complete the Merger and for the issuance of Keane common stock in
connection with the Merger (the Joint Proxy Statement/Prospectus).
Supplemental Disclosures in Connection with Stockholder Litigation in
Connection with the Merger
In connection with the Merger Agreement and the transactions contemplated thereby, one putative class
action complaint has been filed in the United States District Court for the District of Colorado by a purported C&J stockholder on behalf of himself and all other C&J stockholders (excluding defendants and related or affiliated persons)
against C&J and members of the C&J board of directors, two putative class action complaints have been filed in the United States District Court for the District of Delaware by a purported C&J stockholder on behalf of himself and all
other C&J stockholders (excluding defendants and related or affiliated persons) against C&J, members of the C&J board of directors, Keane and Merger Sub, one putative class action complaint has been filed in the United States District
Court for the Southern District of Texas by a purported Keane stockholder on behalf of himself and all other Keane stockholders (excluding defendants and related or affiliated persons) against Keane and members of the Keane board of directors, and
one putative class action has been filed in the Delaware Chancery Court by a purported Keane stockholder on behalf of himself and all other Keane stockholders (excluding defendants and related or affiliated persons) against members of the Keane
board of directors. The five complaints are captioned as follows: Palumbos v. C&J Energy Services, Inc., et al., Case 1:19-cv-02386 (D. Colo.) (Aug. 22,
2019), Wuollet v. C&J Energy Services, Inc., et al., Case 1:19-cv-01411 (D. Del.) (Jul. 29, 2019), Plumley v. C&J Energy Services, Inc., et
al., Case 1:19-cv-01446 (D. Del.) (Aug. 1, 2019), Bushansky v. Keane Group, Inc. et al., Case
4:19-cb-02924 (S.D. Tex) and Woods v. Keane Group, Inc., et al., Case 2019-0590 (Del. Chan.) (Jul. 31, 2019), which we refer to collectively as the
Stockholder Actions. In general, the Stockholder Actions allege that the defendants violated Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act), or aided and abetted in such alleged
violations, because the Joint Proxy Statement/Prospectus allegedly omits or misstates material information. The Stockholder Actions seek, among other things, injunctive relief preventing the consummation of the Merger, unspecified damages and
attorneys fees.
C&J, Keane and the other named defendants believe that no supplemental disclosures are required under
applicable laws; however, to avoid the risk of the Stockholder Actions delaying the Merger and to minimize the expense of defending the Stockholder Actions, and without admitting any liability or wrongdoing, C&J and Keane are making certain
disclosures below that supplement and revise those contained in the Joint Proxy Statement/Prospectus, which C&J and Keane refer to as the litigation-related supplemental disclosures. The litigation-related supplemental disclosures
contained below should be read in conjunction with the Joint Proxy Statement/Prospectus, which is available on the Internet site maintained by the SEC at www.sec.gov, along with periodic reports and other information C&J and Keane file with the
SEC. C&J, Keane and the other named defendants have denied, and continue to deny, that they have committed or assisted others in committing any violations of law, and expressly maintain that, to the extent applicable, they complied with their
legal obligations and are providing the litigation-related supplemental disclosures below solely to try to eliminate the burden and expense of further litigation, to put the claims that were or could have been asserted to rest, and to avoid any
possible delay to the closing of the Merger that might arise from further litigation. Nothing in the litigation-related supplemental disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the
litigation-related supplemental disclosures set forth herein. To the extent that the information set forth herein differs from or updates information contained in the Joint Proxy Statement/Prospectus, the information set forth herein shall supersede
or supplement the information in the Joint Proxy Statement/Prospectus. All page references are to pages in the Joint Proxy Statement/Prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the Joint Proxy
Statement/Prospectus.
