Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Commitments From time to time, the Company may enter into agreements with suppliers that contain minimum purchase obligations and agreements to purchase capital equipment. The Company did not have any unconditional purchase obligations at September 30, 2025. Letters of Credit The Company had outstanding letters of credit related to environmental remediation and insurance programs that were issued under the Company’s revolving credit facility, which is collateralized by substantially all of the assets of the Company, totaling $7.5 million at September 30, 2025 and December 31, 2024. Additionally, at September 30, 2025, the Company had an outstanding letter of credit related to its Settlement Agreement with PREPA totaling $18.4 million, which is cash collateralized at Fifth Third Bank for $19.3 million. See Note 20 - “Subsequent Events” for additional details regarding the release of the letter of credit and related collateral. Insurance The Company has insurance coverage for physical partial loss to its assets, employer’s liability, automobile liability, commercial general liability, workers’ compensation and insurance for other specific risks. The Company has also elected in some cases to accept a greater amount of risk through increased deductibles on certain insurance policies. At September 30, 2025 and December 31, 2024, the workers’ compensation policy required a deductible per occurrence of up to $0.3 million. At September 30, 2025 and December 31, 2024, the Company’s primary automobile liability policy required a deductible per occurrence of up to $0.5 million. As of September 30, 2025 and December 31, 2024, the workers’ compensation and auto liability policies contained an aggregate stop loss of $8.7 million and $5.4 million, respectively. Effective November 1, 2024, the Company became party to a deductible reimbursement insurance policy from a protected cell captive insurance company that covers losses between $0.1 million and the $0.5 million deductible under its primary auto liability policy. Also effective November 1, 2024, the Company became a member of a group captive insurance company that covers one layer of its auto liability coverage. The Company establishes liabilities for the unpaid deductible portion of claims incurred based on estimates. At September 30, 2025 and December 31, 2024, total accrued claims for continuing and discontinued operations were $1.2 million and $1.5 million, respectively. Of this amount, $0.3 million and $0.2 million at September 30, 2025 and December 31, 2024, respectively, relate to continuing operations. The Company also has insurance coverage for directors and officers liability. As of September 30, 2025 and December 31, 2024, the directors and officers liability policy had a deductible per occurrence of $1.0 million and an aggregate deductible of $10.0 million. At September 30, 2025 and December 31, 2024, the Company did not have any accrued claims for directors and officers liability. The Company also self-insures its employee health insurance. The Company has coverage on its self-insurance program in the form of a stop loss of $0.2 million per participant and an aggregate stop-loss of $9.1 million for the calendar year ending December 31, 2025. At September 30, 2025 and December 31, 2024, total accrued claims for continuing and discontinued operations were $0.8 million and $2.3 million, respectively. Of these amounts, $0.5 million at September 30, 2025 and December 31, 2024, relate to continuing operations. These estimates may change in the near term as actual claims continue to develop. Warranty Guarantees Pursuant to certain customer contracts in our infrastructure services segment, the Company warrants equipment and labor performed under the contracts for a specified period following substantial completion of the work. Generally, the warranty is for one year or less. No liabilities were accrued at September 30, 2025 and December 31, 2024 and no expense was recognized during the nine months ended September 30, 2025 and 2024 related to warranty claims. However, if warranty claims occur, the Company could be required to repair or replace warrantied items, which in most cases are covered by warranties extended from the manufacturer of the equipment. In the event the manufacturer of equipment failed to perform on a warranty obligation or denied a warranty claim made by the Company, the Company could be required to pay for the cost of the repair or replacement. Bonds In the ordinary course of business, the Company is required to provide bid bonds to certain customers in the infrastructure services segment as part of the bidding process. These bonds provide a guarantee to the customer that the Company, if awarded the project, will perform under the terms of the contract. Bid bonds are typically provided for a percentage of the total contract value. Additionally, the Company may be required to provide performance and payment bonds for contractual commitments related to projects in process. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay subcontractors and vendors. If the Company fails to perform under a contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. At September 30, 2025 and December 31, 2024, there were no outstanding performance and payment bonds and no outstanding bid bonds that related to the Company's continuing operations. Litigation PREPA Cobra and PREPA previously entered into two agreements to aid in the restoration and reconstruction of Puerto Rico’s power grid in response to damage caused by Hurricane Maria in 2017. PREPA is currently subject to bankruptcy proceedings, which were filed in July 2017 and are currently pending in the Title III Court. Cobra pursued litigation in the Title III Court and other dispute resolution efforts seeking recovery of the amounts owed to Cobra by PREPA for restoration services in Puerto Rico, which proceedings are discussed in more detail in the Company’s prior reports filed with the SEC. As discussed in Note 2, on July 22, 2024, Cobra entered into the Settlement Agreement with PREPA. Pursuant to the terms of the Settlement Agreement, PREPA paid Cobra approximately $168.4 million in 2024 and, as of September 30, 2025, PREPA owes Cobra $20.0 million, which is payable to Cobra within seven days following the effective date of PREPA’s plan of adjustment in its bankruptcy proceedings. Refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, previously filed with the SEC for more information regarding the Settlement Agreement. Other Litigation On May 13, 2021, Foreman Electric Services, Inc. (“Foreman”) filed a petition against Mammoth and Cobra in the Oklahoma County District Court (Oklahoma State Court). The petition asserted claims against the Company and Cobra under federal Racketeer Influenced and Corrupt Organizations Act (“RICO”) statutes and certain state-law causes of action. Foreman alleged that it sustained injuries to its business and property in the amount of $250 million due to the Company’s and Cobra’s alleged wrongful interference by means of inducements to a FEMA official. On May 18, 2021, the Company removed this action to the United States District Court for the Western District of Oklahoma and filed a motion to dismiss on July 8, 2021. On July 29, 2021, Foreman voluntarily dismissed the action without prejudice. On December 14, 2021, Foreman re-filed its petition against Mammoth and Cobra in the Oklahoma County District Court (Oklahoma State Court). On December 16, 2021, the Company again removed this action to the United States District Court for the Western District of Oklahoma. Foreman filed a motion to remand this action back to Oklahoma County District Court, which was granted on May 5, 2022. On September 28, 2023, the Company moved to dismiss the petition. On November 16, 2023, rather than respond to the motion, Foreman filed an Amended Petition naming Arty Straehla, Mark Layton and Wexford as additional defendants, added claims for fraudulent transfer arising out of the refinancing of certain debt and sought receivership over Mammoth and Cobra related to allegedly fraudulently transferred assets. The defendants moved to dismiss the Amended Petition, which was denied on March 12, 2024. On February 8, 2024, Foreman filed a Motion for Appointment of Receiver. On April 29, 2024, the Court denied that motion. Additionally, on February 6, 2023, Foreman moved to amend a complaint against the former president of Cobra filed in Florida State Court arising from facts similar to those in the pending Oklahoma action to add, as defendants, Arty Straehla and Mark Layton. On September 15, 2023, Straehla and Layton moved to dismiss the complaint. On January 18, 2024, Foreman voluntarily dismissed the Florida State Court action against Straehla and Layton. In a related matter, on January 12, 2022, a Derivative Complaint on behalf of nominal defendant Machine Learning Integration, LLC (“MLI”), which alleges it would have served as a sub-contractor to Foreman in Puerto Rico, was filed against the Company and Cobra in the U.S. District Court for the District of Puerto Rico alleging essentially the same facts as Foreman’s action and asserting violations of federal RICO statutes and certain non-federal claims. MLI alleges it sustained injuries to its business and property in an unspecified amount because the Company’s and Cobra’s wrongful interference by means of inducements to a FEMA official prevented Foreman from obtaining work, and thereby prevented MLI, as Foreman’s subcontractor, from obtaining work. During 2024, the Company recognized an estimated liability related to these complaints, which is included in “accounts payable” on the unaudited condensed consolidated balance sheets. In July 2025, the Company settled the matter with Foreman. The settlement did not have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows. The Company is routinely involved in state and local tax audits. During 2015, the State of Ohio assessed taxes on the purchase of equipment the Company believes is exempt under state law. The Company appealed the assessment and a hearing was held in 2017. As a result of the hearing, the Company received a decision from the State of Ohio, which the Company appealed. On February 25, 2022, the Company received an unfavorable decision on the appeal. The Company appealed the decision. On August 2, 2023, the Ohio Supreme Court affirmed the ruling in part and reversed the ruling in part. The Company received the final assessment in April 2025. It did not have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows. Cobra has been served with 14 lawsuits from municipalities in Puerto Rico alleging failure to pay construction excise and volume of business taxes. On November 14, 2022, the Court entered judgment against Cobra in connection with one of the lawsuits ordering payment of approximately $9.0 million. On January 9, 2023, Cobra appealed the judgment and, on March 20, 2023, the Court confirmed the imposition of approximately $8.5 million related to construction excise taxes. On April 10, 2023, Cobra appealed this judgment, which was denied on May 5, 2023. Cobra filed a motion for reconsideration on May 15, 2023, which was denied. Cobra filed a second motion for reconsideration on June 22, 2023 and is currently awaiting a decision. On December 18, 2023, the Humacao Superior Court issued an order to PREPA to withhold payment of approximately $9.0 million to Cobra. On January 17, 2024, Cobra filed a Writ of Certiorari requesting the Court of Appeals to reverse the order from the Humacao Superior Court. On February 15, 2024, Cobra’s request was granted by the Court of Appeals and the order instructing PREPA to withhold the $9.0 million payment from Cobra was revoked. The case was remanded to the lower Court for continuation of the proceedings in accordance with the Court of Appeals’ order. On May 16, 2025 and May 20, 2025, the Court entered judgment against Cobra in connection with two of the lawsuits in the amount of $5.1 million and $1.6 million, respectively, plus interest, penalties and attorneys’ fees. Separately, the Court entered judgment against Cobra in connection with another lawsuit on July 3, 2025, in the amount of $3.4 million. The May 16, 2025 and May 20, 2025 judgments were appealed to the Court of Appeals, which denied the appeals on June 30, 2025. In August 2025, Cobra appealed the Salinas and Humacao (and others) matters to the Supreme Court of Puerto Rico. Also in August 2025, Cobra filed a request for oral arguments. On October 24, 2025, Cobra received a notification from the Supreme Court accepting the cases as certiorari and denying to hear the appeal. Cobra intends to file a motion to reconsider. In connection with the Settlement Agreement entered into with PREPA, PREPA (including through the Puerto Rico Fiscal Agency and Financial Advisory Authority, as fiscal agent for PREPA, and the FOMB) has agreed to cooperate with Cobra and assist in resolving the construction excise and volume of business taxes assessed against Cobra. There is no guarantee, however, that the Company, including with PREPA’s cooperation, will be successful in favorably resolving or mitigating these taxes. Accordingly, at this time, the amount of loss cannot be reasonably estimated. On April 16, 2019, Christopher Williams, a former employee of Higher Power Electrical, LLC, filed a putative class and collective action complaint titled Christopher Williams, individually and on behalf of all others similarly situated v. Higher Power Electrical, LLC, Cobra Acquisitions LLC, and Cobra Energy LLC in the U.S. District Court for the District of Puerto Rico. On June 24, 2019, the complaint was amended to replace Mr. Williams with Matthew Zeisset as the named plaintiff. The plaintiff alleges the defendant failed to pay overtime wages to a class of workers in compliance with the Fair Labor Standards Act and Puerto Rico law. On August 21, 2019, upon request of the parties, the Court stayed proceedings in the lawsuit and administratively closed the case pending completion of individual arbitration proceedings initiated by Mr. Zeisset and opt-in plaintiffs. Other claimants subsequently initiated additional individual arbitration proceedings asserting similar claims. The Company has agreed to settlements with a portion of the claimants. Arbitrations remain pending for the remaining claimants. The Company will continue to vigorously defend the arbitrations. The Company has recognized an estimated liability related to the remaining complaints, which is included in “accounts payable” in the accompanying unaudited condensed consolidated balance sheets. The amount required to resolve these matters may ultimately increase or decrease from the Company’s estimated amount as the matters progress. The Company is involved in various other legal proceedings in the ordinary course of business. Although the Company cannot predict the outcome of these proceedings, legal matters are subject to inherent uncertainties and there exists the possibility that the ultimate resolution of these matters could have a material impact on the Company’s business, financial condition, results of operations or cash flows. Assignment Agreement On December 1, 2023, Cobra, as seller and Mammoth, as guarantor, entered into an assignment agreement (the “Assignment Agreement”) with SPCP Group, LLC (“SPCP Group”), as purchaser. Under the terms and conditions of the Assignment Agreement, Cobra transferred to SPCP Group, at the purchase rate of 88.0% and free and clear of any liens and claims, all of its rights, title and interest in the first $63.0 million (the “Transferred Amount”) of the total outstanding accounts receivable that remained unpaid by PREPA as of October 6, 2023 (the “PREPA Claim”), received or to be received by Cobra on or after October 6, 2023. Between October 6, 2023 and December 1, 2023, Cobra received payments from PREPA with respect to the PREPA Claim totaling $8.6 million (the “Interim Payment Amount”), resulting in the net Transferred Amount of $54.4 million. The net proceeds received by Cobra in connection with the Assignment Agreement were $46.1 million. During the three months ended March 31, 2024, PREPA paid $64.0 million with respect to the outstanding PREPA receivable. Of the $64.0 million, $54.4 million was paid to SPCP Group, as Cobra’s assignee under the Assignment Agreement, which fully extinguished Cobra’s and Mammoth’s obligations to SPCP Group under the Assignment Agreement, and the Assignment Agreement was terminated. The Company recognized a financing charge totaling $5.5 million during the nine months ended September 30, 2024 related to the termination of the Assignment Agreement, which is included in “interest income (expense and financing charges), net” on the unaudited condensed consolidated statements of operations and comprehensive income (loss). Defined Contribution Plan The Company sponsors a 401(k) defined contribution plan for the benefit of substantially all employees at their date of hire. The plan allows eligible employees to contribute up to 92% of their annual compensation, not to exceed annual limits established by the federal government. The Company makes discretionary matching contributions of up to 3% of an employee’s compensation and may make additional discretionary contributions for eligible employees. For the three and nine months ended September 30, 2025 and 2024, the Company paid $0.2 million, $0.9 million, $0.5 million and $1.5 million, respectively, in contributions to the plan. Of these amounts for the three and nine months ended September 30, 2025 and 2024, $0.1 million, $0.4 million, $0.2 million and $0.5 million, respectively, relates to continuing operations.
