("Master Fund") effected a distribution in kind of 5,200,000 shares (the "Shares") of common stock of the Issuer in the aggregate to: (i) its two feeder funds, Luminus Energy Partners QP, LP, a Delaware limited partnership ("LEP Onshore"), which received 2,117,138 Shares, and LEP Offshore (through LILP, an intermediary entity which received 2,641,190 Shares); and (ii) two affiliates that have economic interests in the Master Fund, namely LCP Onshore, which received 391,694 Shares, and LCP Offshore, which received 91,930 Shares. Each of the Funds had issued illiquid certificates to their respective investors on April 1, 2020. In connection with the distribution in kind, the Manager planned to distribute 5,200,000 shares of common stock. As Certificate Holders entitled to receive 1,145,542 shares of common stock (the "Segregated Shares") in the aggregate did not either (i) respond or provide the requisite information to the Fund's administrator and the Manager to receive the Segregated Shares, (ii) were unable to accept delivery of the Segregated Shares or (iii) chose not to participate in the distribution (such Certificate Holders being referred to as the "Non Returners"), the Master Fund continues to hold the Segregated Shares and retains both voting and disposition power over the Segregated Shares. The Master Fund, however, has no economic interest in the Segregated Shares as the Master Fund is holding the Segregated Shares for the benefit of the Non Returners. On September 21, 2026, the Master Fund distributed 187,523 shares of common stock to certain Non Returners who provided their information. As of the date of this report, 20,966 of the Segregated Shares remain undistributed. The Master Fund can, in its discretion, sell the Segregated Shares on behalf of the Non Returners and/or make one or more distribution in kind of the Segregated Shares to the Non Returners who provide their requisite information. Shares reported herein are held by the Master Fund for which Luminus Management, LLC serves as the investment manager. Jonathan Barrett is the ultimate beneficial owner of Luminus Management, LLC. Each of the Reporting Persons disclaims beneficial ownership of the shares reported herein except to the extent of its or his pecuniary interest therein.
