Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9 – Commitments and Contingencies Royalty Agreements The Company has entered into royalty agreements under which it is committed to pay royalties on sand sold from its production facilities for which the Company has received payment by the customer. Atlas LLC entered into a royalty agreement associated with its leased property at the Kermit facility and a mining agreement associated with its leased property at the Monahans facility, in each case, with The Sealy & Smith Foundation, a related party. The royalty agreement associated with the Kermit facility terminated on the date of our initial public offering (the “IPO”), pursuant to the terms of the agreement. Under the mining agreement associated with the Monahans facility, we are committed to pay royalties on product sold from that facility and are required to pay a minimum royalty of $1.0 million for any lease year following our IPO. We have certain royalty obligations based on tonnage of sand sold under land leases associated with our OnCore distributed mining network. On March 1, 2024, the Company entered into a pooling agreement with the General Land Office of Texas that establishes a pooled unit across our fee owned lands and leased lands at the Kermit property. The pooling agreement has a current effective blended royalty rate of 5.86% on the sales of two of the Kermit plants. This pooling agreement increases our operational flexibility by establishing a framework to efficiently mine across our fee owned lands and leased lands interchangeably. Royalty expense associated with these agreements is recorded as the product is sold and is included in cost of sales. Royalty expense associated with these agreements were less than 5% of cost of sales for both the three months ended March 31, 2026 and 2025. Standby Letters of Credit As of both March 31, 2026 and December 31, 2025, we had $0.3 million outstanding in standby letters of credit issued under the 2023 ABL Credit Facility. Purchase Commitments In connection with our normal operations, we enter short-term purchase obligations for products and services. In October 2024, we entered into an agreement to purchase dredge equipment in the amount of approximately $9.8 million with a 25% downpayment applied at placement of the order with the remaining 75% to be paid during delivery and assembly, subject to customary terms and conditions. Delivery of equipment is expected to occur in 2026. As of March 31, 2026, we have spent $7.1 million and have $2.7 million outstanding on this commitment expected to be spent in 2026. In November 2024, we entered into an agreement to purchase logistics equipment for approximately $32.8 million with a 40% downpayment, monthly progress billings, and balance due at readiness to ship, subject to customary terms and conditions. Delivery of certain equipment occurred in 2025 and the remaining delivery is expected to take place in 2026. Subsequent to the purchase agreement, we entered into a lease financing agreement, refer to Note 7 - Leases for further discussion. As of March 31, 2026, there has been $30.0 million spent and $2.8 million outstanding on this commitment expected to be spent in 2026. In February 2025, we entered into an agreement to purchase logistics equipment for approximately $15.8 million with progress billings, subject to customary terms and conditions and applicable shipping and taxes. Under the agreement, we elected to purchase approximately $7.9 million of additional logistics equipment in 2025 and approximately $7.9 million of additional logistics equipment in 2026, subject to customary terms and conditions and applicable shipping and taxes. Delivery of certain equipment occurred in 2025 and the remaining delivery is expected to take place in 2026. Subsequent to the purchase agreement, we entered into a lease financing agreement, refer to Note 7 - Leases for further discussion. As of March 31, 2026, there has been $25.3 million spent and $6.3 million outstanding on these commitments expected to be spent in 2026. In March 2025, a vendor reached key performance and operational milestones that committed the Company to order an initial 100 trucks by March 31, 2026. Subsequent to the purchase agreement, we entered into a debt financing agreement, refer to Note 8 - Debt for further discussion. As of March 31, 2026, we have placed an order for the 100 trucks and have purchased 36 of the 100 trucks. The remaining estimated total cost of our commitment is approximately $15.7 million based on our most recent purchase price, which is subject to change based on market pricing at the time of purchase. In November 2025, we entered into the Reservation Agreement for the manufacture of approximately 240 MW of power generation equipment. The aggregate cost of such equipment is approximately $278.3 million. The Reservation Agreement was assigned to Stonebriar in connection with entry into the Lease Documents. The cost of the investment will be financed under the Lease Documents as progress payments become due. We expect deliveries to begin in late 2026. Pursuant to the Reservation Agreement, the parties agreed to negotiate and enter into an engineering, procurement and construction agreement governing the terms of the manufacture, delivery and installation of the equipment, which is expected to contain customary representations, warranties and agreements of the parties, indemnification obligations and other customary terms and conditions associated therewith. The Reservation Agreement and terms and conditions of sale also contain customary agreements of the parties and customary terms and conditions. As of March 31, 2026, there has been $61.1 million spent and $217.2 million outstanding on this commitment. Spend of $189.5 million is expected in 2026 with the remaining $27.7 million to occur at commissioning. On March 4, 2026, ProjectCo entered into the Global Framework Agreement (the “GFA”) with Caterpillar Inc. (“Caterpillar”) pursuant to which Caterpillar will reserve approximately 1.4 GW (“Reserved Capacity”) of incremental power generation equipment (the “Caterpillar Equipment”) and ProjectCo will commit to purchase the Caterpillar Equipment from certain Caterpillar authorized dealers (“Participating Dealers”) based on ProjectCo’s monthly demand forecast beginning on the effective date of the GFA and ending on December 31, 2030 (the “Term”) for an initial total aggregate purchase obligation of approximately $840.0 million. The initial purchase price for the Caterpillar Equipment is subject to adjustments including annual escalations capped at 8% per year, shipping and transportation and adjustments for tariffs affecting the cost of the Caterpillar Equipment. ProjectCo must pay an annual capacity deposit of $5.0 million (“Advanced Payment”) in June of each year, beginning in 2027, which will be credited towards the purchase price of Caterpillar Equipment. Payment for the Caterpillar Equipment is structured in customary installments. As of March 31, 2026, there has been no spend with $840.0 million outstanding on this commitment. The Company expects to spend through 2029 with delivery of power equipment through 2030. Litigation We are involved in various legal and administrative proceedings that arise from time to time in the ordinary course of doing business. Some of these proceedings may result in fines, penalties or judgments being assessed against us, which may adversely affect our financial results. In addition, from time to time, we are involved in various disputes, which may or may not be settled prior to legal proceedings being instituted and which may result in losses in excess of accrued liabilities, if any, relating to such unresolved disputes. Expenses related to litigation reduce operating income. We do not believe that the outcome of any of these proceedings or disputes would have a significant adverse effect on our financial position, long-term results of operations or cash flows. It is possible, however, that charges related to these matters could be significant to our results of operations or cash flows in any single accounting period. Management is not aware of any legal, environmental or other commitments and contingencies that would have a material effect on the Financial Statements.
