Mammoth Energy Releases Additional Information Regarding Work Performed in Puerto Rico Mammoth Energy Services, Inc. announced that it has posted to its website additional information addressing two documents recently released by the Federal Emergency Management Agency (“FEMA”) that relate to hurricane repair work performed by Cobra Acquisitions LLC (“Cobra”) in Puerto Rico. FEMA released a Determination Memorandum dated May 26, 2021, related to the first of two contracts Cobra successfully performed for the Puerto Rico Electric Power Authority (“PREPA”). Cobra and PREPA executed the Emergency Master Service Agreement for PREPA’s Electrical Grid Repairs – Hurricane Maria on October 19, 2017 (the “Contract”). PREPA has 60 days from the receipt of FEMA’s Determination Memorandum to file an appeal. In addition to the Determination Memorandum, the Company also recently obtained a draft Cost Analysis prepared by FEMA in response to the recommendation of the Department of Homeland Security’s Office of Inspector General (“OIG”) made in an OIG report dated July 3, 2019 (OIG-19-052). The OIG recommended that FEMA conduct a comprehensive analysis of Cobra’s Contract costs and disallow reimbursement to PREPA of any Cobra Contract costs that are not reasonable. In order to address the OIG recommendation, FEMA and the United States Army Corps of Engineers (“USACE”) analyzed the reasonableness of the actual Cobra costs for which PREPA is seeking reimbursement from FEMA. The scope of FEMA’s Cost Analysis included the following: Evaluate Cobra’s overall level of effort and work productivity based on the statement of work (“SOW”) developed by FEMA; Compare Cobra’s actual costs to those of other electrical contractors that performed similar work when the data existed. FEMA reviewed Cobra’s cost of work performed per transmission line (“TL”) and distribution line (“DL”), Cobra’s overall actual average daily rate, and the daily per diem to cover lodging and living expenses; and Reviewed USACE’s report and consider its recommendations prior to making a conclusion on cost reasonableness.
