MAMMOTH ENERGY SERVICES INC

As previously disclosed in the filings with the Securities and Exchange Commission (the “SEC”) made by Mammoth Energy Services, Inc. (“Mammoth” or the “Company”), on July 22, 2024, Cobra Acquisitions LLC (“Cobra”), a wholly-owned subsidiary of Mammoth, entered into a release and settlement agreement with the Puerto Rico Electric Power Authority (“PREPA”) and the Financial Oversight and Management Board for Puerto Rico, in its capacity as PREPA’s representative to the United States District Court for the District of Puerto Rico (the “Title III Court”), to settle all outstanding matters between Cobra and PREPA (the “Settlement Agreement”). Under the terms of the Settlement Agreement, Cobra was allowed an administrative expense claim against PREPA of $170.0 million (plus the $18.4 million in funds received by PREPA from the Federal Emergency Management Agency (“FEMA”) and considered payable to Cobra but for purported garnishments in this amount asserted by three Puerto Rican municipalities (the “Specified Municipalities”) for certain municipal tax claims (the “Specified Municipal Tax Claims”) discussed in Mammoth’s filings with the SEC (the “Withheld FEMA Funds”)). Cobra’s allowed claim is payable through three installments: (i) $150.0 million on the later of (A) ten business days following approval of the Settlement Agreement by the Title III Court and (B) August 31, 2024; (ii) $20.0 million within seven days following the effective date of PREPA’s plan of adjustment; and (iii) $18.4 million in the Withheld FEMA Funds within either (A) ten business days after the deadline for appealing the entry of the settlement order by the Title III Court under the applicable bankruptcy rules of procedure if no such appeal is filed, or (B) if the provisions of the settlement order allowing PREPA to release the Withheld FEMA Funds to Cobra without retaining any liability to the Specified Municipalities are appealed by such municipalities, within ten business days of the filing of the notice of such appeal. Further, upon PREPA’s payment of the Withheld FEMA Funds to Cobra following the notice of appeal described above, Cobra agreed to indemnify and hold PREPA harmless, as well as to provide PREPA with an indemnity letter of credit, solely for any payment(s) PREPA is subsequently required to make pursuant to the Specified Municipalities on account of the Specified Municipal Tax Claims if such order is entered as a result of (i) any reversal on appeal of the settlement order with respect to the Withheld FEMA Funds and/or (ii) the Puerto Rico Court of First Instance or other court of competent jurisdiction enters such order after a diligent challenge by PREPA (including through enforcement of the order approving Settlement Agreement). Any such indemnity obligation will in no event exceed $18.4 million.

As previously announced, on September 18, 2024, the Settlement Agreement was approved by the Title III Court overruling all objections thereto and an order was entered the same day (the “Settlement Order”). On October 1, 2024, Cobra received the first installment payment of $150.0 million from the Commonwealth of Puerto Rico in connection with the Settlement Agreement with PREPA. Also on October 1, 2024, certain Puerto Rico municipalities and Foreman Electric Services Inc. that had objected to approval of the Settlement Order each filed timely notices of appeal of the Settlement Order to the United States Court of Appeals for the First Circuit. None of the foregoing parties have sought a stay of the Settlement Order pending such appeals. Although the ultimate outcome of these appeals cannot be predicted with certainty, Cobra believes that the appeals are without merit.
