PART I

Item 1. Business.

Overview

Atlas Energy Solutions Inc. is a leading proppant producer, logistics, and distributed power solutions provider, primarily serving the Permian Basin of West Texas and New Mexico. We operate our business through two reportable segments: Sand and Logistics and Power. Our mission is to improve human beings’ access to the hydrocarbons that power our lives, and, by doing so, we maximize the value creation for our stockholders. Value creation for our shareholders is our fundamental goal. In order to fulfill our mission and create value for our shareholders, we strive to optimize the outcomes for our broader stakeholders, including our employees and the communities in which we operate. We are proud of the fact that our approach to innovation in the hydrocarbon industry drives efficiencies creating value for our shareholders, while also delivering differentiated social and environmental progress. The Company has driven innovation designed to provide industry-leading environmental benefits by reducing energy consumption, emissions, and our aerial footprint. We call this Sustainable Environmental and Social Progress, and it is driven by shareholder value creation.

We were founded in 2017 by Ben M. "Bud" Brigham, our Executive Chairman, and are led by an entrepreneurial team with a history of constructive disruption bringing significant and complementary experience to this enterprise, including the perspective of longtime E&P operators, which provides for an elevated understanding of the end users of our products and services. Our executive management team has a proven track record with a history of generating positive returns and value creation. Our experience as E&P operators was instrumental to our understanding of the opportunity created by in-basin sand production and supply in the Permian Basin, which we view as North America’s premier shale resource and which we believe will remain its most active through economic cycles.

Segments

Sand and Logistics

We operate 14 proppant production facilities across the Permian Basin including both large-scale in-basin facilities and smaller distributed mining units. We are a low-cost producer of various high-quality, locally sourced proppants used during the well completion process. We offer both dry and damp sand and carry various mesh sizes including 100 mesh and 40/70 mesh. Proppant is a key component necessary to facilitate the recovery of hydrocarbons from oil and natural gas wells. We operate a differentiated logistics platform that is designed to increase the efficiency, safety and sustainability of the oil and natural gas industry primarily within the Permian Basin. This includes our fleet of fit-for-purpose trucks, trailers, wellsite equipment, and the 42-mile Dune Express conveyor system (the only proppant conveyor system in the world, and the longest conveyor in the United States). We are also integrating autonomous driving technologies in certain of our fit-for-purpose trucks, creating the first semi-autonomous oilfield logistics network to increase the automation of the oil and gas proppant supply chain.

Power

We provide distributed power solutions through a fleet of natural gas-powered reciprocating generators primarily supporting production and artificial lift operations across major United States resource basins. Our generators are designed for heavy-duty, harsh environments for mission critical power needs. Our in-house manufacturing and remanufacturing capabilities, coupled with critical in-field service, provide quality control and standardization across the fleet ensuring market-leading uptime.

Assets and Operations

Sand and Logistics

Our Kermit facilities, Monahans facility, and OnCore distributed mining network are located in West Texas. The Kermit facilities consist of the two internally developed Kermit facilities (“K1/K2”) and the two facilities acquired in the Hi-Crush Transaction (“K115/874”). The facilities and OnCore distributed mining network encompass 45,855 gross acres in the aggregate that we own or lease. We have substantial off-dune acreage at Monahans that is not included in our estimated reserves or resources but that could be mined following our removal of material, such as soil and unusable sand, that lies above the useable sand and must be removed to excavate the useable sand, which we refer to as “overburden.”

The Dune Express, which originates at our Kermit facilities and stretches into the middle of the Northern Delaware Basin, is the first long-haul proppant conveyor system in the world. The Dune Express is 42 miles in length, capable of transporting 13 million tons of proppant annually, and is strategically located to deliver proppant to the Northern Delaware Basin. The Dune Express has lowered legacy transportation requirements and increased safety by removing trucks from public roadways, thus reducing traffic, accidents and fatalities on public roadways in the region.

We installed two permanent loadout facilities, one located on the Texas side of the Texas-New Mexico state line approximately at the midpoint of the conveyor and one located at the end of the Dune Express right-of-way on BLM land near the Lea-Eddy County line in New Mexico. The conveyor system also utilizes one or more mobile offload systems, which can be mobilized and relocated from time to time, to maximize delivery efficiencies for customers that are proximate to the conveyor system but not proximate to one of the two permanent loadouts connected to the system.

Power

Our distributed power solutions include a fleet of more than 1,000 natural gas-powered reciprocating generators, with power generation primarily supporting production and artificial lift operations across major United States resource basins.

On November 2, 2025, Atlas LLC entered into a reservation agreement (the “Reservation Agreement”) for the manufacture of approximately 240 megawatts 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 of the equipment 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.

Map of Operations

The following map shows the locations of our operations as of December 31, 2025:

Sand and Logistics

The Kermit facilities and the Monahans facility were built to produce high quality 40/70-mesh and 100-mesh sands, each of which is used extensively in upstream operations in the Permian Basin. Innovative plant design and large-scale operations facilitate low-cost operations and continuity on site. Redundancies were designed into our facilities to remove singular points of failure that could disrupt the production process, ensuring maximum reliability of proppant production and delivery. The facilities are capable of operating year-round and feature advanced safety designs, onsite water supply, power infrastructure and access to low-cost natural gas through connections to interstate natural gas lines. Our OnCore distributed mining network is comprised of 9, built-for-purpose mobile processing plants which produce wet (i.e., undried or damp) 100-mesh sand from leased or customer-owned properties. At each OnCore site, we are responsible for mining and processing the raw sand, selling the finished frac sand products, and reclaiming the disturbed land. The mobility of the OnCore plants provides a great deal of flexibility not afforded to large-scale fixed-plant mining operations.

Further, we benefit from the strategic locations of our facilities, proximal to major highways at the south and north ends of the Winkler Sand Trend. Our Kermit facilities are bisected by two state highways, while our Monahans facility its adjacent to two highways, one of which is Interstate 20, facilitating efficient transportation of our proppant to customers located at various points within the Permian Basin. Accessibility to the western sites for the OnCore mines is via Texas state highway TX-302 or U.S. Route 285; while primary access to the eastern sites is via Interstate 20, state highways TX-137, TX-176, or TX-349.

The operations of our sand facilities are managed and monitored in a highly automated manner from our command center in Austin, Texas. The remote ecosystem allows our employees to simultaneously manage processes at all facilities, resulting in personnel productivity gains.

Our differentiated logistics platform operates primarily within the Permian Basin. This includes our fleet of fit-for-purpose trucks, trailers, wellsite equipment, and the 42-mile Dune Express conveyor system.

Power

Our fleet of generators provides distributed energy solutions for production and artificial lift operations across major United States resource basins.

Our Products and Services

Product

We serve the oil and gas end markets, and our sand reserves contain deposits of fine grade 40/70-mesh and 100-mesh sizes that API specifies for use in wellsite fracturing operations. We believe that this mix of finer grade sand reserves is in higher demand and meets current industry preferences. Based on the reserve report prepared by John T. Boyd Company (“JT Boyd”), our independent mining engineers and geologists, as of December 31, 2025, we had 571.3 million tons of proven and probable sand reserves at our Kermit facilities, Monahans facility, and OnCore distributed mining network. Our reserves were composed of approximately 45% 40/70-mesh, 36% 70/140-mesh, and 19% of 40/140-mesh substrate sand. As of December 31, 2025, we estimate our reserve life to be approximately 29 years for our K1/K2 facilities, 11 years for our K115/874 facilities, 27 years for our Monahans facility, and 20 years for our OnCore distributed mining network, as may be extended or adjusted for future conversions of measured, indicated or inferred resources to proven or probable reserves or any change to our production capacity. For more information regarding our mineral reserves, see Item 2. “Property.—Our Reserves.”

Proppant is stored onsite before transport and delivery to customers’ well sites located primarily in the Delaware and Midland Basins. Our proppant is offered to our customers at the mine or as an integrated mine-to-wellhead solution.

Services and Rentals

We provide transportation, storage solutions, contract labor services and distributed power rentals to companies in the oil and gas industry. Transportation services typically consist of transporting product from the plant facilities to the wellsite. The locations of our facilities are within close proximity to well activity and enable us to deliver proppant directly to our customers’ wellheads using a variety of methods, reducing handling costs and delivery lead times.

Our Permits

We have obtained numerous federal, state and local permits required for operations at our Kermit facilities, Monahans facility, and OnCore distributed mining network. Operations are predominantly regulated by the TCEQ with respect to environmental compliance. The predominant permitting requirement is an active New Source Review (“NSR”) permit for air pollution control. Our operations have a current NSR permit which is renewable next in 2028. Other permits held by our operations include Stormwater, Above Ground Storage Tank, Aggregate Production Operation, and a septic permit. A Spill Prevention, Control, and Countermeasure plan is also active at our locations.

We have obtained DOT operating authority, as defined under U.S. Department of Transportation (“DOT”) and Federal Motor Carrier Safety Administration (“FMCSA”) required for our Last Mile Logistics and Power operations.

While resources invested in securing permits are significant, this cost has not had a material adverse effect on our results of operations or financial condition. We cannot be certain that existing transportation or environmental laws and regulations will not be reinterpreted or revised or that new transportation, or environmental laws and regulations will not be adopted or become applicable to us. Revised or additional requirements that result in increased compliance costs or additional operating restrictions could have a material adverse effect on our business.

Environmental and Occupational Health and Safety Regulations

We are subject to stringent and complex federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to protection of worker health, safety and the environment and natural resources (including threatened and endangered species). Compliance with these laws and regulations may expose us to significant costs and liabilities and cause us to incur significant capital expenditures in our operations. Any failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, imposition of remedial obligations and the issuance of injunctions delaying or prohibiting operations. Certain environmental laws may impose strict, joint and several liability for remediation costs. Private parties may also have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property damage. In addition, the trend in environmental regulation has been to place more restrictions on activities that may affect the environment, and thus, any changes in, or more stringent enforcement of, these laws and regulations that result in more stringent and costly pollution control equipment, the occurrence of delays in the permitting or performance of projects, or waste handling, storage, transport, disposal or remediation requirements could have an adverse effect on our operations and financial position.

We do not believe that compliance by us and our customers with federal, state or local environmental laws and regulations will have an adverse effect on our business, financial position or results of operations or cash flows. We cannot assure you, however, that future events, such as changes in existing laws or enforcement policies, the enactment or promulgation of new laws or regulations or the development or discovery of new facts or conditions adverse to our operations will not cause us to incur significant costs. The following is a discussion of material environmental and worker health and safety laws, as amended from time to time, that relate to our operations or those of our customers that could have an adverse effect on our business.

Worker & Community Health and Safety

We are subject to the requirements of the federal Occupational Safety and Health Administration (“OSHA”), the federal Mine Safety and Health Administration, and comparable state statutes that regulate the protection of the health and safety of workers. In addition, the OSHA hazard communication standard requires that information be maintained about hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities and the public. Similar obligations related to community safety are codified in the Emergency Planning & Community Right to Know Act, as authorized by the Superfund Amendments and Reauthorization Act. These laws and regulations are subject to frequent changes and any failure to comply with these laws could lead to the assertion of third-party claims against us, civil or criminal fines and changes in the way we operate our facilities, which one or more events could have an adverse effect on our financial position. We have an internal program of inspection designed to monitor and enforce compliance with worker safety requirements. Historically, our worker and community health and safety compliance costs have not had an adverse effect on our results of operations.

Air Emissions

Our operations and the operations of our customers are subject to the federal Clean Air Act (“CAA”) and related state and local laws, which restrict the emission of air pollutants and impose permitting, monitoring and reporting requirements on various sources. These regulatory programs may require preconstruction permitting, best available control technology analysis, the installation of emissions abatement equipment, modification of operational practices and obtaining permits or similar authorizations for our operations. Obtaining air emissions permits has the potential to delay the development or continued performance of our operations. Over the next several years, we may be required to incur certain capital expenditures for air pollution control equipment or to address air emissions-related issues as we expand our facilities or develop new ones. Changing and increasingly stricter requirements, future non-compliance or failure to maintain necessary permits or other authorizations could require us to incur substantial costs or suspend or terminate our operations. We could be subject to administrative, civil and criminal penalties as well as injunctive relief for noncompliance with air permits or other requirements of the CAA and comparable state laws and regulations.

Climate Change

In the United States, no comprehensive climate change legislation has been implemented at the federal level. Under previous administrations, the EPA has adopted regulations that, among other things, establish construction and operating permit reviews for emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the United States, and together with the Department of Transportation (the “DOT”), implement GHG emissions limits on vehicles manufactured for operation in the United States. However, in February 2026, the EPA issued a final rule rescinding the “Endangerment Finding,” which provides the basis for the EPA’s authority to regulate GHG emissions. Litigation challenging the final rule is likely, and as a result, there is significant uncertainty with respect to regulations related to GHG emissions. We cannot predict the outcome of potential legal challenges or the ultimate impacts on our business. Notwithstanding the potential Endangerment Finding repeal, the Inflation Reduction Act of 2022 (“IRA”) appropriated significant incentives for renewable energy initiatives and imposed a fee on excess GHG emissions from certain oil and gas facilities, and the EPA issued a final rule in November 2024 implementing the charge. However, in February 2025, Congress repealed the rule using the Congressional Review Act, and the One Big Beautiful Bill Act, enacted in July 2025, and delayed implementation of the charge until 2034. We cannot predict when or whether the Trump administration or Congress may take further action to repeal or revise this requirement in the IRA, if at all, or the resulting impact on our business operations. Additionally, several U.S. states including California and New York, either individually or in regional collaboration, have adopted or are considering adopting legislation, policies, or regulatory initiatives focused on GHG emissions reductions, including cap and trade programs, carbon taxes, performance standards, and reporting and monitoring programs. Internationally, the United Nations-sponsored Paris Agreement (“Paris Agreement”) requires member states to individually determine and submit non-binding emissions reduction targets every five years after 2020. On January 20, 2025, President Trump signed an Executive Order once again withdrawing the United States from the Paris Agreement, and in January 2026, he announced the United States’ withdrawal from the United Nations Framework Convention on Climate Change. While the international community continues to gather annually to develop and negotiate international climate initiatives, pledges, and frameworks, the United States’ participation in future United Nations climate-related conferences and initiatives and the impacts of these orders, pledges, agreements and any legislation or regulation promulgated to fulfill the United States’ commitments under the Paris Agreement or other international agreements cannot be predicted at this time.

Emerging climate-change focused legislation and regulation, litigation efforts, policy directives, and related initiatives have the potential to increase our and our customers’ operating costs and reduce demand for our customers’ products and thereby our services. Further, any limitations or restrictions on the development of fossil fuel-specific infrastructure and our customers’ ability to access capital, develop their assets, and market their products may adversely affect our business and results of operations. For more information on applicable climate change-related regulatory matters, developments and risks affecting our business, please see our “Risk Factors—Risks Related to Environmental, Mining and Other Regulations—Our and our customers’ operations are subject to a number of risks arising out of the threat of climate change, including regulatory, political, litigation and financial risks, which could result in increased operating and capital costs for our customers and reduced demand for our products and services” and “Risk Factors—Risks Related to Our Business and Operations— Increased stakeholder and market attention to ESG and conservation matters may adversely impact our business and access to capital.”

Water Discharges

The federal Clean Water Act (“CWA”) and analogous state laws impose restrictions and strict controls with respect to the discharge of pollutants, including spills and leaks of oil and other substances, into waters of the United States. The discharge of pollutants into regulated waters, including jurisdictional wetlands, is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. The CWA also prohibits the discharge of dredge and fill material in regulated waters, including wetlands, unless authorized by a permit issued by the U.S. Army Corps of Engineers (the “Corps”). Federal and state regulatory agencies can impose administrative, civil and criminal penalties, as well as require remedial or mitigation measures, for non-compliance with discharge permits or other requirements of the CWA and analogous state laws and regulations. In the event of an unauthorized discharge of wastes, we may be liable for penalties and costs.

The scope of waters subject to federal jurisdiction has been subject to substantial controversy, with the Corps and EPA pursuing several rulemakings since 2015 to attempt to define the scope of Waters of the United States (“WOTUS”). Most recently, EPA issued a WOTUS rule in September 2023 that is currently only implemented in 24 states due to ongoing litigation. Thus, the operative definition of WOTUS varies by state. In November 2025, the EPA issued a proposed rule to further update and narrow the definition of WOTUS. To the extent the implementation of the September 2023 rule, challenges to the November 2025 proposed rule, results of the litigation or any action further expands the scope of the CWA’s jurisdiction in areas where we operate, we could face increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas.

Additionally, the process for obtaining permits has the potential to delay our operations. Spill prevention, control and countermeasure requirements of federal laws require appropriate containment berms and similar structures to help prevent the contamination of navigable waters by a petroleum hydrocarbon tank spill, rupture or leak. In addition, the CWA and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties as well as other enforcement mechanisms for non-compliance with discharge permits or other requirements of the CWA and analogous state laws and regulations. The CWA and analogous state laws provide for administrative, civil and criminal penalties for unauthorized discharges and, impose rigorous requirements for spill prevention and response planning, as well as substantial potential liability for the costs of removal, remediation, and damages in connection with any unauthorized discharges.

Hydraulic Fracturing

We supply proppant to the oil and natural gas industry. Hydraulic fracturing is an important common practice that is used to stimulate production of oil and natural gas from low permeability hydrocarbon bearing subsurface rock formations. The hydraulic fracturing process involves the injection of water, proppant and chemicals under pressure into the formation to fracture the surrounding rock, increase permeability and stimulate production. Although we do not directly engage in hydraulic fracturing activities, our customers purchase our proppant for use in their hydraulic fracturing activities. Hydraulic fracturing is typically regulated by state oil and natural gas commissions and similar agencies; however, the EPA has asserted jurisdiction over hydraulic fracturing activities in some circumstances under the Safe Drinking Water Act. Some states have adopted, and other states are considering adopting, regulations that could impose new or more stringent permitting, disclosure or well construction requirements on hydraulic fracturing operations. State and federal regulatory agencies have also recently focused on a possible connection between the operation of injection wells used for oil and natural gas waste disposal and seismic activity. Similar concerns have been raised that hydraulic fracturing may also contribute to seismic activity, and some states, including Texas, have imposed or are considering imposing certain limits on or requirements related to the permitting or operation of produced water disposal wells in areas with increased instances of induced seismic events. Aside from state laws, local land use restrictions may restrict drilling in general or hydraulic fracturing in particular. Municipalities may adopt local ordinances attempting to prohibit hydraulic fracturing altogether or, at a minimum, allow such fracturing processes within their jurisdictions to proceed but regulating the time, place and manner of those processes. At the same time, certain environmental groups have suggested that additional laws may be needed to more closely and uniformly limit or otherwise regulate the hydraulic fracturing process, and legislation has been proposed by some members of Congress to provide for such regulation.

The adoption of new laws or regulations at the federal or state levels imposing reporting obligations on, or otherwise limiting or delaying, the hydraulic fracturing process could make it more difficult to complete natural gas wells, increase our customers’ costs of compliance and doing business and otherwise adversely affect the hydraulic fracturing services they perform, which could negatively impact demand for our proppant. In addition, heightened political, regulatory and public scrutiny of hydraulic fracturing practices could expose us or our customers to increased legal and regulatory proceedings, which could be time-consuming, costly or result in substantial legal liability or significant reputational harm. We could be directly affected by adverse litigation involving us, or indirectly affected if the cost of compliance limits the ability of our customers to operate. Such costs and scrutiny could directly or indirectly, through reduced demand for our proppant, have an adverse effect on our business, financial condition and results of operations.

Non-Hazardous and Hazardous Wastes

The Resource Conservation and Recovery Act (“RCRA”) and comparable state laws control the management and disposal of hazardous and non-hazardous waste. These laws and regulations govern the generation, storage, treatment, transfer and disposal of wastes that we generate. In the course of our operations, we generate waste that are regulated as non-hazardous wastes and hazardous wastes, obligating us to comply with applicable standards relating to the management and disposal of such wastes. In addition, drilling fluids, produced waters and most of the other wastes associated with the exploration, development and production of oil or natural gas, if properly handled, are currently exempt from regulation as hazardous waste under RCRA and, instead, are regulated under RCRA’s less stringent non-hazardous waste provisions, state laws or other federal laws. However, it is possible that certain oil and natural gas drilling and production wastes now classified as non-hazardous could be classified as hazardous wastes in the future. A loss of the RCRA exclusion for drilling fluids, produced waters and related wastes could result in an increase in our customers’ costs to manage and dispose of generated wastes and a corresponding decrease in their drilling operations, which developments could have an adverse effect on our business.

Site Remediation

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and comparable state laws impose strict, joint and several liability on certain classes of persons that contributed to the release of a hazardous substance into the environment without regard to fault or the legality of the original conduct. These persons include the owner and operator of a disposal site where a hazardous substance release occurred and any company that transported, disposed of or arranged for the transport or disposal of hazardous substances released at the site. Under CERCLA, such persons may be liable for the costs of remediating the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. In addition, where contamination may be present, it is not uncommon for the neighboring landowners and other third parties to file claims for personal injury, property damage and recovery of response costs. We have not received notification that we may be potentially responsible for cleanup costs under CERCLA at any site.

Endangered Species

The ESA restricts activities that may affect endangered or threatened species or their habitats. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act (“MBTA”) and bald and golden eagles under the Bald and Golden Eagle Protection Act (“BGEPA”) and analogous state laws. Compliance with these laws may require the implementation of avoidance or mitigation measures or time and place restrictions on certain operations during migration or breeding seasons. The listing of new species as endangered or threatened and the designation of such species’ habitat as critical under the ESA or related laws in areas where we or our customers operate may result in increased costs arising from required species protection measures or operational delays or limitations, either of which could adversely affect our and our customers operations or reduce demand for our services. For more information regarding risks associated with compliance with endangered species laws and regulations, including discussion of certain risks related to the DSL and lesser prairie chicken, please see our “Risk Factors—Risks Related to Environmental, Mining and Other Regulations—Restrictions on our operations and those of our customers intended to protect certain species of wildlife could have an adverse impact on our ability to expand some of our existing operations or limit our customers’ ability to develop new oil and natural gas wells.”

Mining and Workplace Safety

Our proppant production operations are subject to mining safety regulation. The federal Mine Safety and Health Administration (“MSHA”) is the primary regulatory organization governing proppant mining and processing. Accordingly, MSHA regulates quarries, surface mines, underground mines and the industrial mineral processing facilities associated with and located at quarries and mines. The mission of MSHA is to administer the provisions of the Federal Mine Safety and Health Act of 1977 and to enforce compliance with mandatory miner safety and health standards. As part of MSHA’s oversight, representatives perform at least two unannounced inspections annually for each above-ground facility. Failure to comply with MSHA’s regulations could result in the imposition of civil or criminal penalties and fines.

In addition, our operations are subject to a number of federal and state laws and regulations, including the OSHA and comparable state statutes, whose purpose is to protect the health and safety of workers. Also, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities and citizens. Violations of OSHA can result in administrative, civil and criminal enforcement. Moreover, the inhalation of respirable crystalline silica is associated with the lung disease silicosis. There is recent evidence of an association between crystalline silica exposure or silicosis and lung cancer and a possible association with other diseases, including immune system disorders such as scleroderma. These health risks have been, and may continue to be, a significant issue confronting the silica industry. In response to these potential concerns, OSHA promulgated a new rule seeking to lower work exposure to crystalline silica. The rule became effective for general industry in 2018. In June 2022, MSHA launched a new enforcement initiative to better protect U.S. miners from health hazards resulting from repeated overexposure to respirable crystalline silica, and in April 2024, MSHA issued a final rule designed to reduce miner exposures to respirable crystalline silica, including by lowering the permissible exposure limit and establishing an action level for all miners. However, following legal challenges brought against the rule, the U.S. Court of Appeals for the Eighth Circuit temporarily stayed implementation of the rule, and MSHA subsequently announced that it intends to reconsider parts of the rule, although to date no further action has been taken. For more information, please see our “Risk Factors—Risks Related to Environmental, Mining and Other Regulations— Silica-related health issues and legislation, including compliance with existing or future regulations relating to respirable crystalline silica, or litigation could have an adverse effect on our business, reputation or results of operations.”

In addition, concerns over silicosis and other potential adverse health effects, as well as concerns regarding potential liability from the use of silica, may have the effect of discouraging our customers’ use of our silica products and discouraging our insurers from risk. The actual or perceived health risks of mining, processing and handling silica could adversely affect silica producers, including us, through reduced use of silica products, the threat of product liability or employee lawsuits, increased scrutiny by federal, state and local regulatory authorities of us and our customers or reduced financing sources available to the silica industry.

Environmental Reviews

If permits or other authorizations from the federal government are required, our future operations may be subject to broad environmental review under the National Environmental Policy Act, as amended (“NEPA”). NEPA requires federal agencies to evaluate the environmental impact of all “major federal actions” significantly affecting the quality of the human environment. The granting of a federal permit for a major development project, such as a proppant production operations, may be considered a “major federal action” that requires review under NEPA. Procedures for implementing NEPA vary at the agency level, and in their evaluations, federal agencies may consider a broad array of environmental impacts, including, among other things, impacts on air quality, water quality, wildlife (including threatened and endangered species), historic and archeological resources, geology, socioeconomics and aesthetics. NEPA also requires the consideration of practicable alternatives to the project. The NEPA review process, especially the preparation of a full environmental impact statement, can be time consuming and expensive. The purpose of the NEPA review process is to inform federal agencies’ decision-making on whether federal approval should be granted for a project and to provide the public with an opportunity to comment on the environmental impacts of a proposed project. Though NEPA requires only that an environmental evaluation be conducted and does not mandate a particular result, a federal agency could decide to deny a permit or impose certain conditions on its approval, based on its environmental review under NEPA, or a third party could challenge the adequacy of a NEPA review and thereby delay the issuance of a federal permit or approval, which could have an adverse effect on our business. For more information, please see “Risk Factors—Risks Related to Environmental, Mining and Other Regulations—Any restrictions on oil and natural gas development on federal lands have the potential to adversely impact our operations and the operations of our customers.”

Motor Carrier Operations

Among the services we provide, we operate as a motor carrier and therefore are subject to regulation by the DOT and various state agencies. These regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier operations; regulatory safety; hazardous materials labeling, placarding and marking; financial reporting; and certain mergers, consolidations and acquisitions. There are additional regulations specifically relating to the trucking industry, including testing and specification of equipment and product handling requirements. The trucking industry is subject to possible regulatory and legislative changes that may affect the economics of the industry by requiring changes in operating practices or by changing the demand for common or contract carrier services or the cost of providing truckload services. Some of these possible changes include increasingly stringent environmental regulations, changes in the hours of service regulations which govern the amount of time a driver may drive in any specific period and requiring onboard black box recorder devices or limits on vehicle weight and size.

Interstate motor carrier operations are subject to safety requirements prescribed by the DOT. Intrastate motor carrier operations are subject to safety regulations that often mirror federal regulations. Such matters as weight and dimension of equipment are also subject to federal and state regulations. The DOT regulations also mandate drug testing of drivers. From time to time, various legislative proposals are introduced, including proposals to increase federal, state or local taxes, including taxes on motor fuels, which may increase our costs or adversely impact the recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes applicable to us will be enacted.

State and Local Regulation

We are subject to a variety of state and local environmental review and permitting requirements. In some cases, the state environmental review may be more stringent than the federal review. Our operations may require state-law based permits in addition to federal permits, requiring state agencies to consider a range of issues, many the same as federal agencies, including, among other things, a project’s impact on wildlife and their habitats, historic and archaeological sites, aesthetics, agricultural operations and scenic areas. The development of new sites and our existing operations also are subject to a variety of local environmental and regulatory requirements, including land use, zoning, building and transportation requirements.

Demand for proppant in the oil and natural gas industry drove a significant increase in the production of proppant. As a result, some local communities expressed concern regarding silica sand mining operations. These concerns have generally included exposure to ambient silica sand dust, truck traffic, water usage and blasting. In response, certain state and local communities have developed or are in the process of developing regulations or zoning restrictions intended to minimize dust from becoming airborne, control the flow of truck traffic, significantly curtail the amount of practicable area for proppant production activities, provide compensation to local residents for potential impacts of proppant production activities and, in some cases, ban issuance of new permits for proppant production activities. To date, we have not experienced any material impact to the development of our proppant production facilities and do not anticipate an impact on future operations as a result of these types of concerns. We would expect this trend to continue as oil and natural gas production increases.

Competition

The market in which we operate is highly competitive. We compete with both public and private large, national producers and small, regional or local in-basin proppant providers, such as Iron Oak Energy Solutions, Liberty Energy Inc., U.S. Silica Inc., Alpine Silica, Badger Mining Corporation, Vista Proppants and Logistics and Capital Sand Company, among others. Competition in the proppant production industry is based on a number of factors, including product and service quality, reliability of the service provider, the geographic location of facilities and the associated logistics costs of transporting proppant from the supplier to the customer, innovation, etc. The distributed power industry is a highly fragmented market with both small and large public and private companies.

Human Capital and Employees

Our employees are a critical asset to our innovative culture and overall success. We are focused on sustaining a high-performance culture through attracting, engaging, developing, retaining and rewarding top talent. We strive to enhance the economic and social wellbeing of our employees and the communities in which we operate. We seek to provide a welcoming environment for our workforce, with best-in-class training and career development opportunities to enable employees to thrive and achieve their career goals.

As of December 31, 2025, we had a total of 1,511 employees, of which 191 service our corporate headquarter offices and 1,320 work in field locations. None of our employees are represented by labor unions or subject to collective bargaining agreements. We consider our employee relations to be good.

Health and Safety

The health, safety, and wellbeing of our employees is of the utmost importance. We believe that we are an industry leader with a proven track record in safety.

We provide full-time regular employees the option to participate in health and welfare plans, including medical, dental, vision, life and accidental death and dismemberment, accident, critical illness, hospital indemnity and short-term and long-term disability insurance plans. We also offer an Employee Assistance Program which provides employees and their family members access to professional providers to help navigate challenging life events.

Item 1A. Risk Factors.

There are numerous factors that affect our business and operating results, many of which are beyond our control. The following is a summary of significant factors that might cause our future results to differ materially from those currently expected. The risks described below are not the only risks facing our Company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. If any of these risks actually occur, our business, financial position, operating results, cash flows, reserves or our ability to pay our debts and other liabilities could suffer, the trading price and liquidity of our securities could decline and you may lose all or part of your investment in our securities.

Risks Related to Our Business and Operations

Our business operations depend on the level of activity in the oil and natural gas industries, which experience substantial volatility.

Our operations that produce and transport proppant are materially dependent on the levels of activity in oil and natural gas exploration, development and production. More specifically, the demand for the proppant we produce is closely related to the number of oil and natural gas wells completed in geological formations where sand-based proppant is used in fracture treatments. These activity levels are affected by both short- and long-term trends in oil and natural gas prices. Additionally, our distributed power operations are also tied to activity levels in the oil and gas industry, most specifically through levels of spending tied to production, gathering, and treatment activities. In recent years, oil and natural gas prices and, therefore, the level of exploration, development and production activity, have experienced significant volatility.

When oil and natural gas prices decrease, exploration and production companies may reduce their exploration, development, production and well completion activities. During such periods, demand for our products and services, which supply oil and natural gas wells, including our transportation and logistics solutions, may decline, and may lead to a decline in the market price of proppant, if the supply of proppant is not similarly reduced. When demand for proppant increases, there may not be a corresponding increase in the prices for our products or our customers may not increase use of our products, which could have an adverse effect on our business, financial condition and results of operations.

Worldwide economic, political and military events, including tax, trade and tariff policies of the United States and other countries involved in global energy markets, war, terrorist activity, events in the Middle East and initiatives by OPEC+, have contributed, and are likely to continue to contribute, to oil and natural gas price volatility. For example, the recent events in Venezuela and the ongoing armed conflicts between Russia and Ukraine, unrest in Iran, the continuation of, and the escalation in the severity of, these conflicts has led to extreme regional instability, caused dramatic fluctuations in global financial markets and has increased the level of global economic uncertainty, including uncertainty about world-wide oil supply and demand, which in turn has caused increased volatility in commodity prices. Further, the Houthi movement, which controls parts of Yemen, has targeted and launched numerous attacks on Israeli, American and international commercial marine vessels in the Red Sea as the ships approach the Suez Canal, resulting in many shipping companies re-routing to avoid the region altogether and worsening existing supply chain issues, including delays in supplier deliveries, extended lead times and increased cost of freight, impacts to the shipping of oil and gas, insurance and materials. The potential for conflict with Iran, a major oil producer, the Houthi movement in Yemen or the Hezbollah movement in Lebanon has increased as a result of continued, increasing hostilities in the Middle East.

Additionally, warmer than normal winters in North America and other weather patterns may adversely impact the short-term demand for natural gas and, therefore, demand for our products. Reduction in demand for natural gas to generate electricity could also adversely impact the demand for proppant. In addition, any future decrease in the rate at which oil and natural gas reserves are discovered or developed, whether due to increased governmental regulation, limitations on exploration and drilling activity, technological innovations that result in new processes for oil and natural gas production that do not require proppant or other factors, could adversely affect the demand for our products, even in a stronger oil and natural gas price environment. Moreover, the energy transition to a low carbon economy, increased deployment of renewable power generation, renewable fuels and electric vehicles all have the potential to reduce demand for oil and natural gas and consequently the services we provide. The continued or future occurrence of any of these risks could have an adverse effect on our business, financial condition and results of operations.

Our business is subject to the cyclical nature of our customers’ businesses and the oil and natural gas and power industry.

Our business is directly affected by capital spending to explore for, develop and produce oil and natural gas and power in the United States. The oil and natural gas industry is cyclical and historically has experienced periodic downturns in activity. During periods of economic slowdown in one or more of the industries or geographic regions we serve or in the worldwide economy, our customers often reduce their production and capital expenditures by deferring or canceling pending projects, even if such customers are not experiencing financial difficulties. These developments can have an adverse effect on sales of our products and our results of operations.

Weakness in the industries we serve has had, and may in the future have, an adverse effect on our sales and results of operations. A continued or renewed economic downturn in one or more of the industries that we serve, or in the worldwide economy, could cause actual results of operations to differ materially from historical and expected results.

Industry conditions are influenced by numerous factors over which we have no control, including:

Decreased demand for proppant or the development of technically- and cost-effective alternative proppants or new processes to replace hydraulic fracturing would negatively impact our business.

Frac sand is the most commonly used proppant in the completion and re-completion of oil and natural gas wells through hydraulic fracturing. A significant shift in demand from frac sand to other proppants, such as ceramic proppant, the development and use of other effective alternative proppants, or the development of new processes to replace hydraulic fracturing altogether, could cause a decline in demand for frac sand that we produce and would have an adverse effect on our business, financial condition and results of operations.

In addition, fuel conservation measures, alternative fuel requirements and increasing consumer demand for alternatives to oil and natural gas could reduce demand for oil and natural gas. The impact of the reduced demand for oil and natural gas may have an adverse effect on our business, financial condition, prospects, results of operations and cash flows. Additionally, the increased competitiveness of alternative energy sources (such as wind, solar, geothermal, tidal and biofuels) could reduce demand for oil and natural gas and therefore for our products and services, which would lead to a reduction in our revenues and negatively impact our business, financial condition and results of operations.

Our future performance in the proppant market will depend on our ability to succeed in competitive markets and on our ability to appropriately react to potential fluctuations in demand for, and supply of, our products and services.

Our proppant business operates in a highly competitive market that is characterized by a small number of large, national producers and a larger number of small, regional or local producers. Transportation costs are a significant portion of the total cost to customers of proppant (in many instances, transportation costs can represent more than 50% of delivered cost), the proppant market is typically local, and competition from beyond the local area is limited. Further, competition in the industry is based on customer relationships, reliability of supply, consistency and quality of product, customer service, site location, distribution capability, breadth of product offering, technical support and price.

Some of our competitors may have or may develop greater financial, natural and other resources than we have. Periodically, some of our competitors may reduce the pricing that they offer to our customers for a variety of reasons. One or more of our competitors may develop technology superior to ours or may have production facilities located in closer proximity to certain customer locations than we do.

When the demand for hydraulic fracturing services decreases or the supply of proppant available in the market increases, prices in the proppant market can materially decrease. Our competitors may choose to consolidate, which could provide them with greater financial and other resources than we have and improve their competitive positioning. Furthermore, oil and natural gas exploration and production companies and other providers of hydraulic fracturing services have acquired, and in the future may acquire, their own proppant reserves to fulfill their proppant requirements, and these other market participants may expand their existing proppant production capacity, all of which would negatively impact demand for our proppant. In addition, increased competition in the proppant industry could have an adverse impact on our ability to enter into long-term contracts or to enter into contracts on favorable terms.

The carrying value of our property, plant and equipment (“PP&E”) is subject to impairment charges.

PP&E used in operations is assessed for impairment whenever changes in facts and circumstances indicate that the carrying amount of a particular asset may not be recoverable. If we were to experience events, among others, such as a prolonged economic downturn, significant changes to generation facility useful lives, a decrease in the market price of an asset, increased costs, certain negative financial trends, or significant changes to market conditions or the regulatory environment, we could experience future generation facility impairments.

Our distributed power segment is dependent on its relationships with key suppliers to obtain equipment for its business.

Our power generation business is dependent on a sole key supplier for access to the unique equipment used in the provision of our distributed power offering. If we fail to maintain an adequate relationship with this supplier, if we fail to receive equipment from this supplier in a timely manner or if we are required to find an alternative supplier of equipment, then our competitive position may be harmed and our operations, financial conditions and/or cash flows may be negatively impacted.

In addition, the prices of certain equipment may continue to experience inflationary pressures, which may be exacerbated by our reliance on a single key supplier, that could further increase such costs. We may not be able to pass on these costs to our customers, which could have a material adverse impact on our results of operations, financial condition or cash flows.

Unavailability of, and lengthy delays in obtaining, the necessary equipment may result from a number of factors affecting our supplier including capacity constraints, labor shortages or disputes, supplier product quality issues and our supplier’s allocations to other purchasers. These risks can be magnified in a weak economic environment or following increases in demand arising from an economic downturn, but are also generally present due to the nature of our business and its dependence on highly-specialized equipment. Such disruptions could result in our inability to effectively meet the needs of our customers and could result in a material adverse effect on our operations, financial condition or cash flows.

Many of our power systems involve long sales cycles.

The sales cycle for our power systems, from initial contact with potential customers to the commencement of field delivery, may be lengthy. Customers generally consider a wide range of solutions before making a decision to rent or purchase power systems. Before a customer commits to rent or purchase power systems, they often require a significant technical review, assessment of competitive offerings and approval at a number of management levels within their organization. During the time our customers are evaluating our distributed power offerings, we may incur substantial sales and marketing, engineering, and research and development expenses.

Our customers may not continue to outsource their power system needs.

Our customers can evaluate a wide range of applications and equipment to address standby and/or prime power generation needs. As a result of the significant resources and expertise required to develop these systems, certain of these customers have historically chosen to outsource the provision of power generation to Moser and Atlas. To a significant extent, we will depend on customers continuing to outsource their power generation needs. Customers may not continue to outsource as much or any of their power generation needs in the future or may seek alternative solutions. Additionally, the development of alternative mobile power generation technologies or increased grid capacity could reduce the overarching demand for our products and services.

We depend on a few customers for a significant portion of our power solutions segment revenues, and the loss of one or more significant customers could affect our ability to maintain the revenues of our power solutions segment.

In 2025, our power segment derived more than 30% of its total revenues from two customers. If we were to lose this or any of our power solutions segment’s significant customers without finding replacement customers, or if these customers were to change the terms, including pricing terms, on which they buy power solutions from us, it could have a material adverse effect on our business, financial condition, and results of operations.

Distributed power solutions in some applications compete with access to the grid.

Distributed power solutions are an alternative for customers to consider when grid access is unavailable, costly or delayed. Our distributed power service offering could be affected in the event that large-scale utility projects are completed and the associated transmission and distribution networks are established. In this case, customers may only use our service offering as a backup power or bridge power until line power is received.

We expect our power segment to face significant competition in the future as the mobile power industry evolves.

The landscape of the mobile power industry is evolving rapidly, driven by increased demand from numerous end-markets, including those in the data center and energy businesses. As a result, increased competition from within the mobile power industry can likely be expected to occur. Should this materialize, the portion of the total addressable market that we could capture with our power segment will be lower than expected which could translate to lower than expected revenues.

Operation of power generation facilities involves significant risks and hazards customary to the power industry, which we cannot assure our insurance will be adequate to cover.

Power generation involves hazardous activities, including transporting, storing and handling fuel, operating industrial, electrical and other equipment, and connecting to high-voltage transmission and distribution systems. As a result, our assets, employees, contractors, customers, and the general public may be exposed to risks inherent in the nature of our operations, including hazards such as accidents involving high-voltage electrical equipment, environmental hazards, fires or explosions, structural or mechanical failures, and other dangerous incidents. These and other hazards can cause damage to or destruction of our assets or other property and equipment, personal injury or loss of life, pollution or environmental damage, and (or) suspension of operations, and any such event may expose us to liability for substantial damages, fines, or penalties. Although we intend to maintain insurance that we believe is reasonable and prudent under the circumstances to cover our operations and assets, we cannot provide any assurance that our insurance program will be sufficient or effective under all circumstances and against all hazards or liabilities to which we may be subject. Even if we do have coverage for a particular incident, we may be subject to deductibles, caps, and (or) policy limits, and the amount recoverable under our applicable insurance policies may not fully cover the impacts on our revenue or other potential consequences. Furthermore, due to rising insurance costs and changes in the insurance markets, we cannot provide any assurance that our insurance coverage will continue to be available at economic rates or at all.

Expected demand growth from the technology sector, manufacturing industry, and other uses of electricity, which have driven recent improvements in the outlook for the competitive power generation market, may not actually occur or be sustained.

Recently, the market outlook for competitive power generation has improved largely based on expected future demand from several sources, including data centers and other technology sector requirements and applications, re-shoring of manufacturing in the U.S., the electrification of industry more broadly, and other demand drivers. Various factors, including, but not limited to, unfavorable macroeconomic conditions, advancements in energy efficiency or increases in supply, or advances in technology, could result in lower-than-expected electricity demand and unfavorable market conditions for our business. A general economic slowdown or recession, a downturn in technology, manufacturing, or other sectors, an oversupply of generation resources or natural gas, or various other economic conditions could reduce the overall demand for electricity and depress prices. Improvements in energy efficiency, conservation efforts, and demand-side power management technologies, as well as other shifts in energy consumption, may reduce demand or slow demand growth. Furthermore, the penetration of renewable generation resources has, and may continue to have, negative effects on power prices and the economics of dispatchable generation units. Advances in technology may also provide alternative methods to produce, dispatch, and store power, which could also lead to increases in overall electricity supply. Any of these factors could impact the dispatch, capacity factors, and value of our generation facilities.

We may be unable to adapt our distributed power technologies to meet increasing customer needs and power loads, which could result in increased unexpected operational downtime or outages at our power generation facilities and in increased expenses and reduced revenues.

Demand for power has continued to significantly outpace available power generation supply from the grid, with the electrification of the oil and natural gas industry, as an example, straining aging and unreliable power grids. Further, the expanding use of artificial intelligence has led to the expansion of existing data centers and plans for new data centers.

The operation of our power generation facilities, information technology systems and other assets and conduct of other activities subjects us to a variety of risks, including the breakdown or failure of equipment, accidents, security breaches, viruses or outages affecting information technology systems, labor disputes, obsolescence, delivery/transportation problems and disruptions of fuel supply, failure to receive spare parts in a timely manner, failure to effectively manage related power loads, and performance below expected levels. As we expand our distributed power offering, planned and unplanned outages at our power generation facilities may require us to purchase power at then-current market prices to satisfy our commitments or, in the alternative, pay penalties and damages for failure to satisfy them, and could have a material adverse effect on our business and operating results due to the damage to our reputation and the resulting dissatisfaction of our customers. If we are unable to adapt our power generation technologies to meet future demand and customer needs as they evolve, or are otherwise unable to meet their reliability requirements, our business and operating results may be adversely effected. Although we maintain customary insurance for certain of these risks, no assurance can be given that our insurance coverage will be sufficient to compensate us fully in the event losses occur.

Supplier concentration at certain of our power generation facilities and the inability of suppliers to meet their obligations may expose us to significant financial credit or performance risks.

We may rely on a single contracted supplier or a small number of suppliers for the provision of fuel, transportation of fuel, equipment, technology and/or other services required for the operation of our power generation facilities. In addition, certain of our suppliers provide long-term warranties with respect to the performance of their products or services. If any of these suppliers cannot perform under their agreements with us, or satisfy their related warranty obligations, we will need to utilize the marketplace to provide or repair these products and services. There can be no assurance that we will be able to identify suitable alternative products or suppliers at the same or similar costs to us, or at all. We may not be able to enter into replacement agreements on favorable terms or at all. If we are unable to enter into replacement agreements to provide for fuel, equipment, technology and other required services, we would seek to purchase the related goods or services at market prices, exposing us to market price volatility and the risk that fuel and transportation may not be available during certain periods at any price. We may also be required to make significant capital contributions to remove, replace or redesign equipment that cannot be supported or maintained by replacement suppliers, which could have a material adverse effect on the business, financial condition, results of operations, credit support terms and cash flows. The failure of any supplier to fulfill its contractual obligations to us could have a material adverse effect on our financial results. Consequently, the financial performance of our power generation facilities is partially subject to the credit quality of, and continued performance by, our suppliers and vendors.

We may not own the land on which our power generation facilities are located, which could result in disruption to our operations.

We may not own the land on which our power generation facilities are located, and we are, therefore, subject to the possibility of less desirable terms and increased costs to retain necessary land use if we do not have valid leases or rights-of-way or if such rights-of-way lapse or terminate. Although we have obtained rights to construct and operate these assets pursuant to related contractual arrangements, the rights to conduct those activities are subject to certain exceptions, including the term of the contractual arrangement. The loss of these rights, through our inability to renew right-of-way contracts or otherwise, may adversely affect our ability to operate our power generation assets.

Changes in U.S. trade policy and the impact of tariffs could adversely affect our business, results of operations and financial position.

Our business and results of operations may be adversely affected by uncertainty and changes in U.S. trade policies, including tariffs, trade agreements or other trade restrictions imposed by the U.S. or other governments. For example, on April 2, 2025, the U.S. government announced a 10% tariff on product imports from almost all countries and has since announced individualized higher tariffs on certain other countries. Additionally, on June 3, 2025, the U.S. government imposed a 50% tariff on steel imports, an increase from the previously announced 25% tariff. As a result of the current administration’s trade policy, tariffs may increase our and our customers’ raw material input costs. Any further trade restrictions, retaliatory trade measures or additional tariffs could result in higher input costs to produce our products and increased costs to provide our services. To the extent that we are unable to pass all or any of such cost increases on to our customers, such cost increases could adversely affect our returns on investment and limit our ability to pursue future growth projects.

To the extent any such tariffs remain in place for a sustained period of time, or in the event of a global or domestic recession resulting therefrom, our customers could decide to delay currently planned growth projects or forego them entirely, each of which could result in decreased demand for our products and services and adversely affect our results of operations and financial condition.

The ultimate impact of these trade measures on our business operations and financial results is uncertain and may be affected by various factors, including whether and when such trade measures are implemented, the timing when such measures may become effective, and the amount, scope, or nature of such trade measures, and our ability to execute strategies to mitigate the potential negative impacts resulting therefrom.

Past performance by members of our management team, our directors or their respective affiliates may not be indicative of our future performance or an investment in us.

Information regarding performance by, or businesses associated with, our management team, our directors and their affiliates is presented for informational purposes only. Past performance of our management team, our directors and their affiliates is not a guarantee of our future success or similar results. You should not rely on the historical record of the performance of our management team, our directors or their affiliates as being indicative of the future performance of an investment in us or the returns we will, or are likely to, generate going forward.

Increasing costs, a lack of dependability or availability of transportation services or infrastructure or an oversupply of transportation services could have an adverse effect on our business, financial condition and results of operations.

The transportation industry is subject to possible legislative and regulatory changes that may affect the economics of the industry by requiring changes in operating practices or by changing the demand or the cost of providing truckload services.

Transportation and related costs tend to be a significant component of the total delivered cost to our customers purchasing our proppant. The high relative cost of transportation related expense tends to favor manufacturers located in close proximity to the customer. Additionally, increases in the price of transportation costs, including freight charges, fuel surcharges and demurrage costs, could negatively impact operating costs if we are unable to pass those increased costs along to our customers. Failure to find long-term solutions to these logistical challenges could adversely affect our ability to respond quickly to the needs of our customers or result in additional increased costs, and thus could negatively impact our business, results of operations and financial condition.

Our operations are subject to operational hazards and inherent risks, some of which are beyond our control, and some of which may not be fully covered by insurance.

Our business and operations may be affected by natural or man-made disasters and other external events, many of which are not in our control. In addition to the other risks described in these risk factors, risks include:

These hazards can also cause personal injury and loss of life, severe damage to and destruction of property and equipment, pollution or environmental damage and suspension or cancellation of operations. Any prolonged downtime or shutdowns at our mining properties or production facilities could have an adverse effect on our business, financial condition and results of operations. In addition, our operations are subject to, and exposed to, employee/employer liabilities and risks such as wrongful termination, discrimination, labor organizing, retaliation claims and general human resource related matters.

Not all of these risks are reasonably insurable, and our insurance coverage contains limits, deductibles, exclusions and endorsements. Our insurance coverage may not be sufficient to meet our needs in the event of loss and any such loss may have an adverse effect on our business, financial condition and results of operations.

Our ability to produce our products economically and in commercial quantities could be impaired if we are unable to acquire adequate supplies of water for our dredging operations.

The dredging process that we currently employ to produce from our Kermit, Texas and Monahans, Texas proppant production and processing facilities requires significant quantities of water from the aquifer underlying our acreage. If in the future there is insufficient capacity available from this aquifer to provide a source of water for our dredging and associated processes as a result of drought or similar conditions affecting the environment, we will be required to obtain water from other sources that may not be readily available, or may be too costly, and we may be unable to continue our dredge mining operations entirely. The effects of climate change may also further exacerbate water scarcity in certain regions, including at the aquifer on our acreage. If an environmental, weather or other event were to require us to discontinue dredging and resume operations using traditional proppant production processes, this could impair our cost of operations and ability to economically produce our product and would have an adverse effect on our financial condition, results of operations and cash flows.

Failure to maintain effective quality control systems at our mining and production facilities could have an adverse effect on our business, financial condition and operations.

The quality and safety of our products are critical to the success of our business. These factors depend significantly on the effectiveness of our quality control systems, which, in turn, depend on a number of factors, including the design of our quality control systems, our quality-training program and our ability to ensure that our employees adhere to the quality control policies and guidelines. Any significant failure or deterioration of our quality control systems could have an adverse effect on our business, financial condition, results of operations and reputation.

Given the nature of our proppant production operations, we face a material risk of liability, delays and increased cash costs of production from environmental and industrial accidents and operational breakdowns.

Our business involves significant risks and hazards, including environmental hazards, industrial accidents and breakdowns of equipment and machinery. Our electric dredge mining operations are subject to delays and accidents associated with electrical supply, repositioning and maintenance. Furthermore, during operational breakdowns, the relevant facility may not be fully operational within the anticipated timeframe, which could result in further business losses. The occurrence of any of these or other hazards could delay production, suspend operations, increase repair, maintenance or medical costs and, due to the integration of our facilities, could have an adverse effect on the productivity and profitability of a particular facility or on our business as a whole. Although insurance policies provide limited coverage for these risks, such policies will not fully cover some of these risks.

Successful operation of the Dune Express will depend on certain factors that may be outside of our control, and the storage and transportation capacity or other anticipated benefits of our Dune Express may not be achieved.

We may encounter adverse geological conditions, regulatory procedures or other legal requirements that could impede the operation of the Dune Express. The inability to obtain any permits and other federal, state or local approvals that may be required, and any excessive delays in obtaining such permits and approvals due, for example, to litigation or third-party appeals, could potentially prevent us from successfully operating the Dune Express in a timely manner.

We could also face difficulties meeting certain delivery obligations to our customers or incur additional costs in making such deliveries by truck or other alternative means. Any material delay caused by our subcontractors could impact our ability achieve the anticipated benefits of the Dune Express and its integrated mining facilities and have an adverse effect on our business, financial condition and results of operations.

Operation of the Dune Express will depend on transmission and distribution facilities. If transmission to the Dune Express or any of its integrated mining facilities were to be interrupted physically, mechanically or with cyber means, it may hinder our ability to mine, sell or deliver proppant to our customers, satisfy our contractual obligations or otherwise operate or fully realize the expected benefits of the Dune Express.

Increased stakeholder and market attention to ESG and conservation matters may adversely impact our business and access to capital.

Businesses across all industries face scrutiny from stakeholders related to their ESG approach and practices. Businesses that are perceived to be operating in contrast to investor or stakeholder expectations and standards, which are continuing to evolve, or businesses that are perceived to have not responded appropriately with respect to ESG issues, regardless of whether there is a legal requirement to do so, may suffer from reputational damage and the business, financial condition, access to capital, and/or stock price of such business entity could be materially and adversely affected. Increased societal, investor, regulator, and stakeholder attention to climate change, natural capital, and other ESG matters along with changes in consumer demand for alternative sources of energy may result in increased costs (including but not limited to increased costs related to compliance, stakeholder engagement, contracting, and insurance) and reduced demand for our customers’ hydrocarbon products and our products and services. Increased and sometimes conflicting investor, lender, and societal expectations regarding voluntary ESG-related disclosures and trends towards mandatory ESG-related disclosures could result in increased costs, heightened regulatory, judicial, and legislative scrutiny, governmental investigations, and litigation. From time to time, we may also be subject to ESG-specific activist campaigns as stockholders may attempt to effect changes to our business or governance practices.

In addition, certain organizations that provide information, ratings or proxy advisory services to investors on corporate governance and related matters have developed processes for evaluating companies on their approach to ESG matters. Such ratings or recommendations are used by some investors to inform their investment and voting decisions. Accordingly, we may receive pressure from certain investors, lenders or other groups to adopt climate or other ESG-related goals or commitments or to participate in various voluntary frameworks or certification programs intended to improve our ESG profile. A failure or a perception (whether valid or not) of failure to adequately pursue or implement ESG strategies or adopt ESG goals or commitments which are often aspirational, including any voluntary GHG emission reduction or carbon intensity goals or commitments, could result in litigation or reputational damage, cause investors or customers to lose confidence in us, harm our ability to effectively recruit or retain employees and negatively impact our operations and goodwill, all of which may adversely affect our financial performance. Moreover, even if we voluntarily elect to pursue climate or ESG goals or commitments, we cannot guarantee that we will be able to pursue or implement such goals or commitments because of potential costs, technical or operational obstacles, uncertainty and inaccuracies in long-term assumptions and expectations or other market or technological developments beyond our control. Similarly, we cannot guarantee that participation in any sustainability, climate-related, or ESG certification program or framework will have the intended results on our ESG profile.

Separately, some members of the investment community have increased their focus on the ESG practices and disclosures of public companies, including practices and disclosures related to climate change and sustainability, employment practices and social initiatives, and heightened governance standards. Certain large institutional investors may also evaluate companies for ESG disclosure and performance prior to investing in our Company or including our Company’s stock in their investment products, and such evaluation criteria may not be made known to us. Although this trend has waned recently, to the extent financial institutions choose not to invest in our Company on account of their evaluation of our ESG performance or a decision to allocate capital away from or cease to insure the fossil fuel production sector, we may lose investors, our cost of capital may increase, and our stock price may be negatively impacted.

Certain public statements with respect to ESG matters, such as emission reduction goals, other environmental targets, or other commitments addressing certain social issues, are becoming increasingly subject to heightened scrutiny from public and governmental authorities, as well as other parties, related to the risk of potential “greenwashing,” (i.e., misleading information or false claims overstating potential ESG benefits). For example, federal and state agencies have taken enforcement action against companies for ESG-related misconduct, including alleged greenwashing. Such regulators, as well as non-governmental organizations and other private actors, have also filed lawsuits under various securities and consumer protection laws alleging that certain ESG-statements, emission reduction claims, approaches to accounting for GHG emissions reductions, or other ESG-related goals, or standards were misleading, false, or otherwise deceptive. Any alleged claims of greenwashing against us or others in our industry may lead to further negative sentiment and diversion of investments. Additionally, we could face increasing costs as we attempt to comply with and navigate further ESG-related focus and scrutiny.

Additionally, certain employment or business practices and social initiatives are the subject of scrutiny by both those calling for the continued advancement of such policies, as well as those who believe they should be curbed, including government actors, and the complex regulatory and legal frameworks applicable to such initiatives continue to evolve. We cannot be certain of the impact of such regulatory, legal and other developments on our business.

Our business may suffer if we lose or are unable to attract and retain members of our workforce.

We depend to a large extent on the services of our senior management team and other key personnel. These employees have extensive experience and expertise in evaluating and analyzing industrial mineral properties, maximizing production from such properties, marketing industrial mineral production and developing and executing financing and hedging strategies.

Competition for management and key personnel is intense, and the pool of qualified candidates is limited. The loss of any of these individuals or the failure to attract additional personnel as needed could have an adverse effect on our operations and could lead to higher labor costs or the use of less-qualified personnel. In addition, if any of our executives or other key employees were to join a competitor or form a competing company, we could lose customers, suppliers, know-how and other personnel. Our operations also rely on skilled laborers using modern techniques and equipment to mine efficiently. We may be unable to train or attract the necessary number of skilled laborers to maintain our operating costs.

With respect to our trucking services, the industry periodically experiences a shortage of qualified drivers, particularly during periods of economic expansion, in which alternative employment opportunities are more plentiful and freight demand increases, or during periods of economic downturns, in which unemployment benefits might be extended. The trucking industry suffers from a high driver turnover rate, which requires us to continually recruit a substantial number of drivers to operate our equipment and could negatively affect our operations and expenses if we are unable to do so. Our success will be dependent on our ability to continue to attract, employ and retain highly skilled personnel at all levels of our operations.

A shortage of skilled labor together with rising labor costs in the excavation industry may further increase operating costs, which could adversely affect our business, results of operations and financial condition.

Efficient sand excavation using modern techniques and equipment requires skilled laborers, preferably with several years of experience and proficiency in multiple tasks, including processing of mined minerals. If there is a shortage of experienced labor in areas in which we operate, we may find it difficult to hire or train the necessary number of skilled laborers to perform our own operations, which could have an adverse impact on our business, results of operations and financial condition.

As a result of the volatility of the oilfield services industry and the demanding nature of the work, workers may choose to pursue employment in fields that offer a more desirable work environment at wage rates that are competitive. Increased competition for their services could result in a loss of available, skilled workers or at a price that is not as advantageous to our business, both of which could negatively affect our operating results. If we are unable to retain or meet the growing demand for skilled technical personnel, our operating results and our ability to execute our growth strategies may be adversely affected.

Inaccuracies in our estimates of sand reserves and resource deposits, or deficiencies in our title to those deposits, could result in our inability to mine the deposits or require us to pay higher than expected costs.

We base our sand reserve and resource estimates on engineering, economic and geological data assembled and analyzed by our mining engineers, which are reviewed periodically by outside firms. However, frac sand reserve estimates are by nature imprecise and depend to some extent on statistical inferences drawn from available drilling data, which may prove unreliable. There are numerous uncertainties inherent in estimating quantities and qualities of frac sand reserves and non-reserve frac sand deposits and costs to mine recoverable reserves, many of which are beyond our control and any of which could cause actual results to differ materially from our expectations. These uncertainties include:

In addition, title to, and the area of, mineral properties and water rights may also be disputed. Mineral properties sometimes contain claims or transfer histories that examiners cannot verify. A successful claim that we do not have title to one or more of our properties or lack appropriate water rights could cause us to lose any rights to explore, develop and extract any minerals on that property, without compensation for our prior expenditures relating to such property. Any inaccuracy in our estimates related to our mineral reserves and non-reserve mineral deposits, or our title to such deposits, could result in our inability to mine the deposits or require us to pay higher than expected costs.

Further, the SEC has adopted amendments to its disclosure rules (the “SEC Modernization Rules”) to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Exchange Act, which are codified in Regulation S-K subpart 1300. Under the SEC Modernization Rules, the historical property disclosure requirements for mining registrants included in SEC Industry Guide 7 have been replaced. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources.” However, compared to mineralization that has been characterized as reserves, mineralization described using these terms has a greater amount of uncertainty as to their existence and whether they can be mined legally or economically, and investors are therefore cautioned not to assume that any reported “measured mineral resources,” “indicated mineral resources” or “inferred mineral resources” are or will be economically or legally mineable.

All of our product revenue is currently generated at facilities in West Texas. Any adverse developments at those facilities could have an adverse effect on our business, financial condition and results of operations.

All of our product revenue is currently derived from our Kermit and Monahans facilities located in Winkler and Ward Counties in Texas and the OnCore distributed mining network located in West Texas. Any adverse development at these facilities due to catastrophic events or weather, adverse government regulatory impacts, transportation-related constraints or any other events that could cause us to curtail, suspend or terminate operations at any of our facilities, could result in our being unable to deliver our contracted volumes and related obligations. Although we maintain insurance coverage to cover a portion of these types of risks, there could be potential risks associated with our operations not covered by insurance. There also may be certain risks covered by insurance where the policy does not reimburse us for all of the costs related to such risks. Downtime or other delays or interruptions to our future operations that are not covered by insurance could have an adverse effect on our business, results of operations and financial condition. In addition, under our supply contracts, if we are unable to deliver contracted volumes, we may be required to pay liquidated damages that could have an adverse effect on our financial condition and results of operations.

Our operations consume large amounts of natural gas and electricity. An increase in the price or a significant interruption in the supply of these or any other energy sources could have an adverse effect on our business, financial condition and results of operations.

Natural gas and electricity costs in our sand and logistics segment represented approximately 1.3% and 2.8%, respectively, of our total product revenue in the year ended December 31, 2025, and 1.0% and 1.3%, respectively, of our total product revenue in the year ended December 31, 2024. Potential climate change regulations or carbon or emissions taxes could result in higher cost of production for energy, which may be passed on to us in whole or in part. A significant increase in the price of energy that is not recovered through an increase in the price of our products and services or covered through our hedging arrangements or an extended interruption in the supply of electricity or natural gas to our production facilities could have an adverse effect on our business, results of operations and financial condition.

A large portion of our revenue is generated by our top 10 customers, and the loss of or a significant reduction in purchases by our largest customers could adversely affect our business, financial condition and results of operations.

Our 10 largest customers accounted for approximately 82.4% of total revenue for the year ended December 31, 2025, and approximately 82.0% of total revenue for the year ended December 31, 2024. Some of our customers have exited or could exit the business, or have been or could be acquired by other companies that purchase proppant solutions or logistics services we provide from other third-party providers. Our current customers also may seek to acquire proppant or logistics services from other providers that offer more competitive pricing or capture and develop their own sources of proppant solutions or logistics services. The loss of a customer or contract, or a reduction in the amount of proppant solutions or logistics services purchased by any customer, could have an adverse effect on our business, financial condition and results of operations. Further, as a result of market conditions, competition or other factors, these customers may not continue to purchase the same levels of our products in the future, if at all. Substantial reductions in purchased volumes across these customers could have an adverse effect on our business, financial condition and results of operations.

Upon the expiration of our current contracts, our customers may not continue to purchase the same levels of proppant solutions or logistics services due to a variety of reasons. In addition, we may choose to renegotiate our existing contracts on less favorable terms or at reduced volumes in order to preserve relationships with our customers. Any renegotiation of our contracts on less favorable terms, or inability to enter into new contracts on economically acceptable terms upon the expiration of our current contracts, could have an adverse effect on our business, financial condition and results of operations.

Our business and operations depend on our and our customers’ ability to obtain and maintain necessary permits.

We and our customers hold numerous governmental, environmental, mining and other permits and approvals authorizing operations at each of our facilities. Our future success depends on, among other things, our ability, and the ability of our customers, to obtain and maintain the necessary permits and licenses required to conduct operations. In order to obtain permits and renewals of permits in the future, we may be required to prepare and present data to governmental authorities pertaining to the impact that our activities may have on the environment. Compliance with these regulatory requirements is expensive and significantly lengthens the time needed to conduct operations. Additionally, obtaining or renewing required permits is sometimes delayed, conditioned or prevented due to community opposition, opposition from other parties, the location of existing or proposed third-party operations, or other factors beyond our control. The denial of a new or renewed permit essential to our operations, delays in obtaining such a permit or the imposition of conditions in order to acquire the permit could impair our ability to continue operations at the affected facilities, delay those operations, or involve significant unplanned costs, any of which could adversely affect our business, performance and financial condition.

Our supply agreements may preclude us from taking advantage of increasing prices for proppant or mitigating the effect of increased operational costs during the term of those contracts.

The supply agreements we have may negatively impact our results of operations. Our sales contracts require our customers to pay a specified price for a specified volume of proppant. Although some of our supply agreements provide for price adjustments based on various factors, such adjustments are generally calculated on a quarterly basis and do not adjust dollar-for-dollar with adjustments in spot market prices. As a result, in periods with increasing prices our sales will not keep pace with market prices.

Additionally, if our operational costs increase during the terms of our supply agreements, we will not be able to pass some of those increased costs to our customers. If we are unable to otherwise mitigate these increased operational costs, our net income could decline.

A proppant production facility closure entails substantial costs, and if we close any of our facilities sooner than anticipated, our results of operations may be adversely affected.

We base our assumptions regarding the life of our proppant production facilities on detailed studies that we perform from time to time, but our studies and assumptions do not always prove to be accurate. If we close any of our proppant production facilities sooner than expected, sales will decline unless we are able to increase production at any of our other proppant production facilities, which may not be possible. The closure of a proppant production facility may also involve significant fixed closure costs, including accelerated employment legacy costs, severance-related obligations and potentially advance employee notice obligations and attendant costs with respect to a plant closure or mass layoff, and potentially reclamation and other environmental costs and the costs of terminating long-term obligations, including energy contracts and equipment leases. We accrue for the estimated costs to retire the assets over the expected timing of settlement. If we were to reduce the estimated time to settlement, the fixed proppant production facilities closure costs could be applied to a shorter period of production, which would increase production costs per ton produced and could adversely affect our results of operations and financial condition.

In addition, some environmental laws such as CERCLA, impose strict, retroactive and joint and several liability for the remediation of releases of hazardous substances.

Certain of our contracts contain provisions requiring us to deliver minimum amounts of sand-based proppant. If we are unable to meet our minimum requirements under these contracts, we may be required to pay penalties or the contract counterparty may be able to terminate the agreement.

In certain instances, we commit to deliver products under penalty of nonperformance. We commit to deliver products to our customers prior to production, and we are obligated to deliver a minimum volume of sand-based proppant per year or per month under our supply agreements over their respective terms. Depending on the contract, our inability to deliver the requisite volume of sand-based proppant may permit our customers to terminate the agreement or require us to pay our customers a fee, the amount of which is generally calculated by multiplying the difference between the amount of volume contracted for and the amount delivered by a per-ton penalty specified in the contract. In such events, our results of operations may be adversely affected.

Currently, a majority of our operations are concentrated in the Permian Basin, making us vulnerable to risks associated with operating in a limited geographic area.

Currently, a majority of our operations are geographically concentrated in the Permian Basin. As a result, we may be disproportionately exposed to various factors, including, among others: (i) the impact of regional supply and demand factors, (ii) delays or interruptions of completion activity in such areas caused by governmental regulation, (iii) processing or transportation capacity constraints, (iv) market limitations, (v) availability of equipment and personnel or (vi) water shortages or other drought related conditions. This concentration in a limited geographic area also increases our exposure to changes in local laws and regulations, certain lease stipulations designed to protect wildlife and unexpected events that may occur in the regions such as natural disasters, seismic events, industrial accidents or labor difficulties. Any of the risks described above could have an adverse effect on our business, financial condition, results of operations and cash flow.

An increase in the supply of proppant having similar characteristics as the proppant we produce could make it more difficult for us to renew or replace our existing contracts on favorable terms, or at all.

If significant new reserves of proppant are discovered and developed and have similar characteristics to the proppant we produce, we may be unable to renew or replace our existing contracts on favorable terms, if at all. Specifically, if proppant is oversupplied, our customers may not be willing to enter into long-term take-or-pay contracts, may demand lower prices or both, which would have an adverse effect on our business, results of operations and financial condition. Similarly, the COVID-19 pandemic caused a historic slowdown in oil and natural gas activity, which led to an increase in available proppant supply relative to the reduced demand. The foregoing events have led to increased competition among our competitors, which could lead to pressure to further reduce prices to compete effectively.

Our results of operations are significantly affected by the market price of sand-based proppant, which has been historically subject to substantial price fluctuations.

Our results of operations and financial conditions are, and will continue to be, particularly sensitive to the long- and short-term changes in the market price of sand-based proppant. Among other factors, these prices also affect the value of our reserves and inventories, and could negatively impact the market price of our Common Stock.

Market prices are affected by numerous factors beyond our control, including, among others, demand for high quality sand-based proppant, the availability and relative cost of alternate sources of sand, drilling and completion activity in the Permian Basin, prevailing commodity prices and overall economic activity.

Additionally, when demand for sand-based proppant increases, there may not be a corresponding or immediate increase in the prices for our products or our customers may choose to opt for lower-quality, lower-priced products, which could have an adverse effect on our results of operations and financial condition. For the years ended December 31, 2025, 2024, and 2023, our average price was approximately $21.00 per ton, $25.26 per ton, and $42.63 per ton, respectively.

In addition, any future decreases in the rate at which oil and natural gas reserves are discovered or developed, whether due to increased governmental regulation, limitations on exploration and drilling activity, including hydraulic fracturing or other factors, could have an adverse effect on our business and financial condition, even in a stronger oil and natural gas price environment.

Our E&P customers’ operations are subject to operating risks that are often beyond our control and could have an adverse effect on our business, financial condition and results of operations.

In addition to the sand-based proppant that we supply, the operations of our E&P customers rely on several other products and services in order to perform hydraulic fracturing activities, such as skilled laborers and equipment required for pumping proppant, water and fluids into oil and natural gas wells. Any failure by our E&P customers to obtain these other products and services could have an adverse effect on our business, financial condition and results of operations.

There are complex software and technology systems that need to be developed in coordination with our technology partner in connection with our autonomous trucking initiative, and there can be no assurance such systems will be successfully developed or implemented for use in our applications or at all.

Our autonomous trucking technology is based on an artificial intelligence (“AI”) software platform. Our autonomous proppant-delivery vehicles use a substantial amount of third-party software codes and complex hardware to operate. The development of these advanced technologies is inherently complex, and we coordinate with our technology partner in connection with the design, production and deployment of our autonomous proppant-delivery vehicles. Defects and errors may be revealed over time and our control over the performance of such third-party services and systems may be limited. Accordingly, our potential inability to successfully develop and implement the necessary software and technology systems may harm our competitive position.

The autonomous trucking technologies are emerging technologies that may not be commercially viable or may not result in an adequate return of capital when used in our planned applications or at all. There can be no assurances that our technology partner will be able to meet the technological requirements, production timing and end-use specifications required to successfully implement our planned autonomous trucking initiative. As with all AI platforms, there can be no guarantee that our technology partner will adequately train our autonomous trucking platform over time to appropriately operate within our business or provide the services and functionalities suited for our needs. Our autonomous trucking platform is dependent on our technology partner’s obligation to develop and maintain the underlying platform, and any failure by our technology partner, or any vendors it relies on, to do so may adversely impact our business and the deployment of this technology. For example, AI algorithms that we use may be flawed or may be based on datasets that are biased or insufficient. In addition, any latency, disruption, or failure in our AI systems or infrastructure could result in delays or errors in our offerings. Developing, testing, and deploying resource-intensive AI systems may require additional investment and increase our costs, while diverting management’s attention. Any material delays or cost increases may also make us unable to meet certain proppant-delivery obligations to our customers or incur additional costs in making such deliveries by traditional trucking methods or other alternative means, which could have an adverse effect on our business, financial condition and results of operations.

Our autonomous driving technology and related hardware and software, when deployed, could have undetected defects, errors or bugs in hardware or software, which could create safety or cybersecurity issues and could result in operational disruption and expose us to liability and other claims that could adversely affect our business.

Autonomous driving technology is highly technical and very complex, and has in the past and may in the future experience defects, errors or bugs at various stages of implementation. In the event of such defect, error or bug, we may incur significant additional development costs, repair or replacement costs, or more importantly, liability for personal injury or property damage caused by such errors or defects. Our insurance coverage may not be sufficient to cover all the losses or expenses that may arise in connection with the planned applications of our autonomous delivery vehicles. In accidents involving semi-trucks, most of the resulting fatalities are victims outside of the vehicle. If we experience such an event or multiple events, our insurance premiums could significantly increase or insurance may not be available to us at all. In addition, lawmakers or governmental agencies could pass laws or adopt regulations that limit the use of autonomous-trucking technology or increase liability associated with its use. Any of these events could adversely affect our reputation, relationships with our customers, financial condition and results of operations.

In addition, we could face legal claims and regulatory investigations and enforcement, penalties and fines as a result of these problems. Any such lawsuit, investigation or enforcement action may cause irreparable damage to our brand and reputation. In addition, defending a lawsuit, regardless of its merit, or complying with an investigation or enforcement action could be costly and may divert management’s attention and adversely affect the market’s perception of us and our products and services. In addition, our insurance coverage could prove inadequate with respect to a claim and future coverage may be unavailable to us on acceptable terms or at all. These product-related issues could result in claims against us and have an adverse effect on our business, financial condition and results of operations.

Any unauthorized control or manipulation of the information and operational technology systems in our autonomous proppant-delivery vehicles could result in loss of customer confidence in us and the products and services we provide.

Our autonomous proppant-delivery vehicles contain complex information and operational technology systems and built-in data connectivity to log location data and accept and install periodic remote updates to improve or update their functionality or performance. Our technology partner expects to design, implement and test security measures intended to prevent unauthorized access to its and our information and operational technology networks, the autonomous vehicle platforms it produces and related or connected systems. However, hackers may attempt to gain unauthorized access to modify, alter and use such networks, vehicles and systems to gain control of or to change our autonomous vehicles’ functionality, user interface and performance characteristics, or to gain access to data stored in or generated by our autonomous vehicles. Future vulnerabilities could be identified and manipulated and our or our technology partner’s efforts to remediate such vulnerabilities may not be successful. Any unauthorized access to or control of our autonomous proppant-delivery vehicles, or any loss of data, could result in legal claims or proceedings or regulatory investigations and enforcement against us and remediation of such problems could result in significant, unplanned capital expenditures. In addition, regardless of their veracity, reports of unauthorized access to our autonomous proppant-delivery vehicles or our or our customers’ data, as well as other factors that may result in the perception that our autonomous proppant-delivery vehicles or data are capable of being “hacked,” could negatively affect our brand and harm our business, financial condition and results of operations.

Our use of autonomous proppant-delivery vehicles is subject to evolving laws and regulations that could impose legal limitations or substantial costs on our ability to commercially deploy our vehicles.

There are a variety of local, state, and federal regulations that may apply to, and adversely affect, the design, training, and operation of autonomous vehicles in the areas in which we operate. This includes many existing vehicle standards that were not originally intended to apply to vehicles that may not be operated by a human driver. Such regulations, including their enforcement or the enforcement policy associated with the regulations, continue to rapidly change, which increases the likelihood of a patchwork of complex or conflicting regulations, or may delay, restrict or prohibit the availability of certain functionalities of our vehicles, which could adversely affect our business. There are also a growing variety of laws and regulations focused on the development, use, and provision of AI technologies, which are difficult to predict and could result in monetary penalties or other regulatory actions. We may not be able to anticipate new laws or regulations governing our use of AI-powered trucking technologies or predict how new laws or regulations will be interpreted for our business and the operation of our vehicles, which could result in adverse effects on our financial condition, reputation, and our operations.

Natural disasters and unusual weather conditions could disrupt business and result in operational delays and otherwise have an adverse effect on our business.

The occurrence of one or more natural disasters, such as tornadoes, hurricanes, tsunamis, fires, droughts, floods and earthquakes or unusual weather conditions or temperatures in the regions in which our facilities are located could result in delayed operations, repair costs or disruptions to our supply chains or similarly impact the operations of our customers. For example, in February 2021, Texas and New Mexico experienced record-setting cold temperatures from Winter Storm Uri. Proppant volumes were negatively impacted in February and March 2021 as the cold weather delayed completion schedules and pushed forecasted producer activity into the latter half of the year. Events such as this could have an adverse effect on our or our customers’ businesses and may become more frequent or intense as a result of climate change.

Our acquisitions, dispositions and investments may not result in anticipated benefits and may present risks not originally contemplated, which may have a material adverse effect on our liquidity, financial condition and results of operations.

We continually seek opportunities to maximize efficiency and value in our Company, which includes consideration of purchases or sales of assets, businesses, or investments. Such strategic transactions, among others, would be intended to (but may not) result in the realization of savings, the creation of efficiencies, the generation of cash or income, or the reduction of risk. Acquisition transactions may use cash on hand or be financed by additional borrowings or by the issuance of Common Stock. Such transactions could also affect our liquidity, financial condition and results of operations.

Such transactions would also involve risks, and we cannot ensure that:

Risks Related to Our Financial Condition

Our indebtedness could adversely affect our financial flexibility and our competitive position.

We have, and expect to maintain in the near term, a significant amount of indebtedness. Under our 2023 ABL Credit Facility, including the amendments, the lenders thereunder provide revolving credit financing to Atlas LLC in an aggregate principal amount of up to $125.0 million with availability thereunder subject to a borrowing base as described in the 2023 ABL Credit Agreement. As of the date of this filing, we were using $0.3 million for outstanding letters of credit, leaving $67.9 million of borrowing availability under our 2023 ABL Credit Facility.

In accordance with the Hi-Crush Merger Agreement, the Company issued the Deferred Cash Consideration Note for an aggregate principal amount of $111.3 million. The Deferred Cash Consideration Note bears interest at a rate of 5.00% per annum if paid in cash, or 7.00% per annum if paid in kind. Interest on the Deferred Cash Consideration Note is payable quarterly in arrears beginning March 29, 2024 through the maturity date of January 31, 2026. As of December 31, 2025, we had an outstanding principal balance of $10.0 million remaining under the Deferred Cash Consideration Note.

On February 21, 2025, Atlas LLC entered into the 2025 Term Loan Credit Agreement with Stonebriar, as administrative agent and initial lender, pursuant to which Stonebriar extended Atlas LLC the 2025 Term Loan Credit Facility comprised of a $540.0 million single advance term loan that was made on February 21, 2025. The Company used the proceeds from the 2025 Term Loan Credit Facility (i) to refinance the existing 2023 Term Loan Credit Facility and the ADDT Loan (as defined in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.—Debt Agreements”), (ii) to finance the cash consideration for the Moser Acquisition, and (iii) for general corporate purposes.

On December 26, 2025, the Company entered into the Lease Documents, by and between Galt and Stonebriar, pursuant to which Galt assigned the Reservation Agreement for the manufacture of approximately 240 megawatts of power generation equipment to Stonebriar and Stonebriar agreed to lease such power generation equipment back to Galt. Pursuant to the Lease Documents, Stonebriar will make periodic advances up to $385.0 million and Galt will make payments to Stonebriar in two phases. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Developments—Master Lease Agreement and Interim Funding Agreement” for additional information.

Our debt agreements contain a number of significant covenants that may limit our ability to, among other things:

Our indebtedness could also have important consequences to you and significant effects on our business, including:

We will need substantial additional capital to operate our business, and the inability to obtain needed capital or financing, on satisfactory terms, or at all, whether due to restrictions in our 2023 ABL Credit Facility, 2025 Term Loan Credit Facility, Lease Documents or otherwise, could have an adverse effect on our growth and profitability.

Our business plan requires a significant amount of capital expenditures to maintain and grow our production levels over the long term. Although we currently use a significant amount of our cash reserves and cash generated from our operations to fund the maintenance and development of our existing sand reserves, we may need to depend on external sources of capital to fund future capital expenditures if proppant prices were to decline for an extended period of time, if the costs of our operations were to increase substantially or if other events were to occur that reduce our sales or increase our costs. Our ability to obtain bank financing or to access the capital markets for future equity or debt offerings may be limited by our financial condition at the time of any such financing or offering, adverse market conditions or other contingencies and uncertainties that are beyond our control. Our failure to obtain the funds necessary to maintain, develop and increase our asset base could adversely impact our growth and profitability.

In addition, our existing 2023 ABL Credit Facility, 2025 Term Loan Credit Facility and Lease Documents contain, and any future financing agreements we may enter into could also contain, operating and financial restrictions and covenants that may limit our ability to finance future operations or capital needs or to engage in, expand or pursue our business activities.

Our ability to comply with these restrictions and covenants is uncertain and will be affected by the levels of cash flow from our operations and events and circumstances beyond our control. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. If we violate any of the restrictions or covenants in our 2023 ABL Credit Facility, 2025 Term Loan Credit Facility or Lease Documents, a significant portion of our indebtedness may become immediately due and payable and our lenders’ commitment to make further loans to us may terminate. We might not have, or be able to obtain, sufficient funds to make these accelerated payments. In addition, our obligations under our 2025 Term Loan Credit Facility are secured by substantially all of our assets, and if we are unable to repay our indebtedness or satisfy our other obligations under these, the lenders could seek to foreclose on our assets.

Even if we are able to maintain existing financing or access the capital markets, incurring additional debt may significantly increase our interest expense and financial leverage, and our indebtedness could restrict our ability to fund future development and acquisition activities. In addition, the issuance of any additional equity interests may result in significant dilution to the holders of our Common Stock.

Risks Related to Our Organizational Structure and Ownership of the Common Stock

We may not resume our dividend program and there is no guarantee that we will repurchase shares of our Common Stock in the future.

We have paid a quarterly dividend or distribution for many years, and commencing in the second quarter of 2023 we established base quarterly dividend of $0.15 per share and paid an additional variable dividend of $0.05 per share per quarter, amounting to a total dividend payment of $0.20 per share. In February 2024, we increased the base dividend to $0.16 per share, amounting to a total dividend payment of $0.21 per share. The variable dividend was increased to $0.06 in May 2024, amounting to a total dividend payment of $0.22 per share. In August 2024, we declared an increased dividend to common stockholders of $0.23 per share and elected to move away from the base plus variable dividend structure to a standalone base dividend. In October 2024, we increased the dividend to $0.24 per share and then in February 2025, we increased the dividend to $0.25 per share. Despite establishing this base dividend in 2023, our Board has not yet adopted a dividend policy, and in November 2025, we announced that the suspension of our quarterly dividend program in order to safeguard the long-term strength of our balance sheet and preserve capital flexibility for growth opportunities, including in our power segment. The declaration and amount of future dividends is at the discretion of our Board and will depend on our financial condition, results of operations, cash flows, prospects, industry conditions, capital requirements and other factors and restrictions our Board deems relevant. The likelihood that dividends will remain suspended is increased during periods of prolonged market weakness or uncertainty, such as the economic downturn that resulted from the COVID-19 pandemic, the oil price collapse in 2020 and the current oil price environment. In addition, our ability to pay dividends may be limited by agreements governing our indebtedness now or in the future. There can be no assurance that we will resume our dividend program in the future.

In October 2024, our Board authorized a share repurchase program that allows us to repurchase up to $200.0 million of our outstanding Common Stock, but the exact number of shares to be repurchased is not guaranteed, and the program may be modified, suspended or discontinued at any time without prior notice. During the year ended December 31, 2025, the Company repurchased 16,380 shares of Common Stock through open-market purchases under the share repurchase program, at an average price, including commission, of $12.21 per share, for an aggregate purchase price of $200,000. The Company is not obligated to repurchase any dollar amount or number of shares under the program. Any elimination of, or downward revision in, our share repurchase program could have an adverse effect on the market price of our Common Stock.

Future sales of Common Stock in the public market, or the perception that such sales may occur, could reduce the trading price of the Common Stock, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in our Company.

Subject to certain limitations and exceptions, the Legacy Owners holding shares of Common Stock may sell those shares in the future. Certain Legacy Owners who own, in the aggregate, approximately 36% of the Common Stock, are party to the A&R Registration Rights Agreement, which includes provisions pursuant to which we have agreed, after the expiration of any applicable lock-up period, to register under the U.S. federal securities laws the offer and resale of shares of Common Stock by such Legacy Owners or certain of their respective affiliates or permitted transferees under the A&R Registration Rights Agreement.

On February 3, 2025, the Company conducted an underwritten public offering of 11.5 million shares of our Common Stock at a public offering price of $23.00 per share. We may also sell additional shares of Common Stock in subsequent offerings. Sales of substantial amounts of our Common Stock in the public market, or the perception that these sales may occur, could cause the market price of our Common Stock to decline. In addition, the sale of such shares, or the perception that such sales may occur, could impair our ability to raise capital through the sale of additional common or preferred stock.

We cannot predict with certainty the size of future issuances of Common Stock or the effect, if any, that future issuances and sales of shares of Common Stock will have on the market price of the Common Stock. Sales of substantial amounts of Common Stock (including shares issued in connection with an acquisition, upon expiration of lock-ups, early release of these agreements or otherwise), or the perception that such sales could occur, may adversely affect prevailing market prices of the Common Stock.

Certain of the Principal Stockholders will have the ability to direct the voting of a significant proportion of the voting power of the Common Stock, and their interests may conflict with those of other stockholders.

In connection with the consummation of the Up-C Simplification, the Principal Stockholders entered into the A&R Stockholders’ Agreement with the Company. The Principal Stockholders collectively own approximately 36% of the Company’s voting stock as of February 21, 2025. As a result, on a combined basis, the Principal Stockholders have considerable influence over matters requiring stockholder approval, including the election of directors, changes to our organizational documents and significant corporate transactions. This concentration of ownership makes it unlikely that any other holder or group of holders of Common Stock will be able to affect the way the Company is managed or the direction of its business. The interests of the Principal Stockholders with respect to matters potentially or actually involving or affecting the Company, such as future acquisitions, financings and other corporate opportunities and attempts to acquire the Company, may conflict with the interests of other stockholders. Given this significant concentrated ownership, the Principal Stockholders would likely have to approve any potential acquisition of the Company.

The A&R Stockholders’ Agreement provides Mr. Brigham (or his affiliates, as applicable) with the right to designate certain numbers of nominees to the Board and the right to approve certain actions by the Company, so long as the Principal Stockholders and their affiliates collectively beneficially own specified percentages of the outstanding shares of Common Stock. Additionally, the A&R Stockholders’ Agreement provides that the Principal Stockholders agree to cause their respective shares of Common Stock to be voted in favor of the election of each of the director nominees designated by Mr. Brigham.

Accordingly, Mr. Brigham has the ability to strongly influence the election of the members of the Board, and thereby its management and affairs. In addition, the Principal Stockholders are able to strongly influence the outcome of all matters requiring stockholder approval, including mergers and other material transactions. This ownership by the Principal Stockholders may also have the effect of deterring hostile takeovers, delaying or preventing changes in control or changes in management, or limiting the ability of other stockholders to approve transactions that they may deem to be in the best interests of the Company. Moreover, this ownership by the Principal Stockholders may also adversely affect the trading price of the Common Stock to the extent investors perceive a disadvantage in owning stock of a company with such concentrated ownership.

Certain of the Principal Stockholders and members of the Board are not limited in their ability to compete with the Company, and the corporate opportunity provisions in the Charter permit certain of the Principal Stockholders and members of the Board to benefit from corporate opportunities that might otherwise be available to us.

The Charter provides that the Principal Stockholders and any member of the Board who is not at the time an officer of the Company, or their respective affiliates are not restricted from owning assets or engaging in businesses that compete directly or indirectly with the Company and that the Company renounces any interest or expectancy in any business opportunity that may be from time to time presented to the Principal Stockholders and any member of the Board who is not at the time an officer of the Company, or their respective affiliates. In particular, subject to the limitations of applicable law, the Charter, among other things:

The Principal Stockholders or any member of the Board who is not at the time an officer of the Company, or their respective affiliates, may become aware, from time to time, of certain business opportunities (such as acquisition opportunities) and may direct such opportunities to other businesses in which they have invested, in which case the Company may not become aware of or otherwise have the ability to pursue such opportunity. Further, such businesses may choose to compete with the Company for these opportunities, possibly causing these opportunities to not be available to the Company or causing them to be more expensive for the Company to pursue. In addition, the Principal Stockholders and any member of the Board who is not at the time an officer of the Company, and their respective affiliates, may dispose of mining or other properties or other assets in the future, without any obligation to offer the Company the opportunity to purchase any of those assets. As a result, the Company’s renouncing of its interest and expectancy in any business opportunity that may be from time to time presented to the Principal Stockholders and any member of the Board who is not at the time an officer of the Company, and their respective affiliates, could adversely impact the Company’s business or prospects if attractive business opportunities are procured by such parties for their own benefit rather than for the Company’s.

Certain of the Principal Stockholders or their affiliates are established participants in the oil and natural gas industry and may have resources greater than ours, which may make it more difficult for the Company to compete with the Principal Stockholders or their affiliates with respect to commercial activities as well as for potential acquisitions. We cannot assure you that any conflicts that may arise between us and our stockholders, on the one hand, and the Principal Stockholders or their affiliates, on the other hand, will be resolved in our favor. As a result, potential competition from the Principal Stockholders or their affiliates could adversely impact our results of operations.

Anti-takeover provisions in our organizational documents might discourage or delay acquisition bids or merger proposals, which may adversely affect the market price of the Common Stock and limit the price investors might be willing to pay in the future for the Common Stock.

The Charter and Bylaws contain provisions that may discourage unsolicited takeover proposals that stockholders may consider to be in their best interests. These provisions:

These anti-takeover provisions could discourage, delay or prevent a transaction involving a change in control of the Company altogether, even if doing so would benefit our stockholders. These provisions could also discourage proxy contests and make it more difficult for our stockholders to elect directors of their choosing and to cause the Company to take other corporate actions our stockholders desire. Further, the A&R Stockholders’ Agreement, the staggered Board and the ability of the Board to designate the terms of and issue new series of preferred stock may make the removal of management more difficult and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

The Charter designates the Court of Chancery of the State of Delaware and, to the extent enforceable, the federal district courts of the United States of America as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit such stockholders’ ability to obtain a favorable judicial forum for disputes with the Company or our directors, officers, employees or agents.

The Charter provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware does not have jurisdiction, the Superior Court of the State of Delaware, or, if the Superior Court of the State of Delaware does not have jurisdiction, the United States District Court for the District of Delaware, in each case, subject to that court having personal jurisdiction over the indispensable parties named defendants therein) will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring (i) any derivative action or proceeding brought on the Company’s behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of the Company’s current or former directors, officers, employees or stockholders to the Company or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, the Charter or the Bylaws (as either may be amended or restated), or as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware, the Charter or Bylaws, or (v) any other action asserting a claim against the Company that is governed by the internal affairs doctrine.

The Charter also provides that, unless the Company consents in writing to an alternate forum, to the fullest extent permitted by applicable law, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. If a court were to find the exclusive-forum provisions contained in the Charter to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business.

To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of the Charter described in the preceding sentence. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with the Company or our directors, officers, employees or agents, which may discourage such lawsuits against the Company and such persons. Alternatively, if a court were to find these provisions of the Charter inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, the Company may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

We may issue preferred stock the terms of which could adversely affect the voting power or value of the Common Stock.

The Charter authorizes the Company to issue, without the approval of its stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over Common Stock respecting dividends and distributions, as the Board may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of the Common Stock. For example, the Company might grant holders of preferred stock the right to elect some number of its directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences the Company might assign to holders of preferred stock could affect the residual value of the Common Stock.

As a result of the Up-C Simplification, the anticipated net cash tax savings attributable to our prior Up-C structure are no longer available to us. The loss of these tax benefits is likely to adversely impact our future tax liability, and this adverse impact could significantly outweigh any costs savings and/or other benefits that resulted from the Up-C Simplification, which could adversely affect our liquidity or the value of our Common Stock.

Under our previous Up-C structure, exchanges of Operating Units for Old Atlas Class A Common Stock pursuant to the terms of the Previous Atlas Operating LLC Agreement generally resulted in certain tax basis increases related to Atlas Operating’s assets. These tax basis increases were expected to generate additional depreciation, depletion, and amortization deductions which in turn, would have reduced our taxable income and resulted in reduced cash tax liabilities. The Company’s exchange of Operating Units for Common Stock in connection with the tax-deferred Up-C Simplification is not expected to result in any such tax basis increases, except to the extent of the limited amount of gain that might have been recognized by the holders of Operating Units as a result of certain debt-financed deductions. Moreover, following completion of the Up-C Simplification, because no Operating Units are held by any person other than Old Atlas, there will be no future exchanges of Operating Units for shares of Old Atlas Class A Common Stock or the Company’s Common Stock. Accordingly, the net cash tax savings that were expected to be available to Old Atlas under the previous Up-C structure are no longer be available to us since the completion of the Up-C Simplification. Foregoing these potential cash tax savings attributable to the Up-C structure will likely to increase our tax liability materially, and such increased tax liability could significantly outweigh the anticipated benefits of the Up-C Simplification, reducing the amount of cash available to use in our business or distribute to our stockholders, which could adversely affect our liquidity or the value of our Common Stock.

The Company’s structure following the Up-C Simplification may impact our ability to offer equity consideration in acquisitive transactions on a tax-deferred basis, which could increase the price we must pay in such acquisition or adversely affect our ability to compete with other potential acquirors.

Our previous Up-C structure permitted us to use Operating Units, rather than Old Atlas Class A Common Stock, as equity consideration in acquisitive transactions. Due to the classification of Atlas Operating as a partnership for U.S. federal income tax purpose, many sellers in potential acquisitive transactions would have been able to receive Operating Units, but not shares of Old Atlas Class A Common Stock, as tax-deferred consideration for assets or equity of a target company, making Operating Units a preferable form of equity consideration. The Up-C Simplification eliminated our ability to offer Operating Units as equity consideration, such that we may not be able to offer tax-deferred equity consideration to potential sellers, while many other companies in the energy industry are organized as partnerships and would have this ability. As such, our inability to offer tax-deferred equity consideration in acquisitive transactions could require us to pay more for assets or target companies than we previously would have or could adversely affect our ability to compete with other potential acquirors.

Risks Related to Environmental, Mining and Other Regulations

Silica-related health issues and legislation, including compliance with existing or future regulations relating to respirable crystalline silica, or litigation could have an adverse effect on our business, reputation or results of operations.

We are subject to laws and regulations relating to human exposure to crystalline silica. For example, OSHA has implemented rules establishing a more stringent permissible exposure limit for exposure to respirable crystalline silica and provided other provisions to protect employees. These rules require compliance with engineering control obligations to limit exposures to respirable crystalline silica in connection with hydraulic fracturing activities. In June 2022, the DOL’s MSHA launched a new enforcement initiative to better protect U.S. miners from health hazards resulting from repeated overexposure to respirable crystalline silica. MSHA reports that silica dust affects thousands of miners each year and, without adequate protection, miners face risks of serious illnesses, many of which can be fatal.

As part of the program, MSHA will conduct silica dust-related mine inspections and expand silica sampling at mines, while providing mine operators with compliance assistance and best practices to limit miners’ exposure to silica dust.

Specifically, the silica enforcement initiative will include:

In addition, pursuant to the initiative, MSHA stated that the DOL’s Educational Field and Small Mine Services staff will provide compliance assistance and outreach to mine operators, unions and other mining community organizations to promote and advance protections for miners.

The MSHA initiative is intended to take action to reduce the risks of silica dust exposure as the DOL’s development of a mining industry standard continues. Then, in a related subsequent regulatory action, on April 18, 2024, MSHA published a final rule designed to reduce miner exposure to respirable crystalline silica. Under the final rule, which stated that it would take effect in June 2024, the uniform permissible exposure limit for respirable crystalline silica was set at 50 micrograms per cubic meter of air and the action level was set at 25 cubic meters of air for all mines. The rule also set requirements for monitoring and controlling exposure to respirable crystalline silica, requires medical surveillance at certain mines, and updates existing respiratory protection requirements to match industry standards. We could face increased compliance costs as a result of this rule. However, following legal challenges brought against the rule, the U.S. Court of Appeals for the Eighth Circuit temporarily stayed implementation of the rule in April 2025, and MSHA subsequently announced that it intends to reconsider parts of the rule, although to date no further action has been taken. We cannot predict whether or not such efforts will ultimately be successful.

If we are unable to satisfy regulatory obligations, or are not able to do so in a manner that is cost effective or attractive to our customers, our business operations may be adversely affected or availability or demand for our products could be significantly affected. Federal and state regulatory authorities, including OSHA and MSHA, and analogous state agencies may continue to propose changes in their regulations regarding workplace exposure to crystalline silica, such as permissible exposure limits and required controls and personal protective equipment, and we can provide no assurance that we will be able to comply with any future laws and regulations relating to exposure to crystalline silica that are adopted, or that costs of complying with such future laws and regulations or any costs arising from non-compliance would not have an adverse effect on our operating results by requiring us to modify or cease our operations.

In addition, the inhalation of respirable crystalline silica is associated with health risks, including the lung disease silicosis. There is evidence of an association between crystalline silica exposure or silicosis and lung cancer and possible association with other diseases, including immune system disorders such as scleroderma. These health risks have been, and may continue to be, a significant issue confronting the hydraulic fracturing industry. Concerns over silicosis and other potential adverse health effects, as well as concerns regarding potential liability from the use of frac sand, may have the effect of discouraging our customers’ use of frac sand. The actual or perceived health risks of handling frac sand could adversely affect hydraulic fracturing service providers, including us, through reduced use of frac sand, the threat of product liability or employee lawsuits naming us as a defendant, increased scrutiny by federal, state and local regulatory authorities of us and our customers or reduced financing sources available to the hydraulic fracturing industry.

Over the past few decades, a number of companies that utilize silica in their operations have been named as a defendant, usually among many defendants, in numerous product liability lawsuits brought by or on behalf of current or former employees or customers alleging damages caused by silica exposure. The silica-related litigation brought against us to date and associated litigation costs, settlements and verdicts have not resulted in a material liability to us, and we presently maintain insurance policies where available. However, we may continue to have silica exposure claims filed against us in the future, including claims that allege silica exposure for periods or in areas not covered by insurance, and the costs, outcome and impact to us of any pending or future claims is not certain. Any such pending or future claims or inadequacies of our insurance coverage could have a material adverse effect on our business, reputation, financial condition, and results of operations.

Federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing and the potential for related litigation could result in increased costs, additional operating restrictions or delays for our customers, which could cause a decline in the demand for our proppant and negatively impact our business, results of operations and financial condition.

We supply proppant to hydraulic fracturing operators in the oil and natural gas industry. Hydraulic fracturing is an important practice that is used to stimulate production of oil and natural gas from low permeability hydrocarbon bearing subsurface rock formations. The hydraulic fracturing process involves the injection of water, proppant, and chemicals under pressure into the formation to fracture the surrounding rock, increase permeability and stimulate production.

Although we do not directly engage in hydraulic fracturing activities, our customers purchase our proppant for use in their hydraulic fracturing activities. Hydraulic fracturing is typically regulated by state oil and natural gas commissions and similar agencies. Some states have adopted, and other states are considering adopting, regulations that could impose new or more stringent permitting, disclosure or well construction requirements on hydraulic fracturing operations. Aside from state laws, local land use restrictions may restrict drilling in general or hydraulic fracturing in particular. Municipalities may adopt local ordinances attempting to prohibit hydraulic fracturing altogether or, at a minimum, allow such fracturing processes within their jurisdictions to proceed but regulating the time, place and manner of those processes. In addition, federal agencies have started to assert regulatory authority under the Safe Drinking Water Act over the process. At the same time, certain environmental groups have suggested that additional laws may be needed and, in some instances, have pursued voter ballot initiatives to more closely and uniformly limit or otherwise regulate the hydraulic fracturing process, and legislation has been proposed by some members of Congress to provide for such regulation. Similar concerns have been raised that hydraulic fracturing may also contribute to seismic activity, and some states, including Texas, have imposed or are considering imposing certain limits on or requirements related to the permitting or operation of produced water disposal wells in areas with increased instances of induced seismic events.

The adoption of new laws or regulations at the federal, state or local levels imposing reporting obligations on, or otherwise limiting, delaying, restricting, or prohibiting the hydraulic fracturing process could make it more difficult to complete oil and natural gas wells, increase our customers’ costs of compliance and doing business, and otherwise adversely affect the hydraulic fracturing services they perform, which could negatively impact demand for our proppant. In addition, heightened political, regulatory, and public scrutiny of hydraulic fracturing practices could expose us or our customers to increased legal and regulatory proceedings, which could be time- consuming, costly, or result in substantial legal liability or significant reputational harm. We could be directly affected by adverse litigation involving us, or indirectly affected if the cost of compliance limits the ability of our customers to operate. Such costs and scrutiny could directly or indirectly, through reduced demand for our proppant, have an adverse effect on our business, financial condition and results of operations.

We and our customers are subject to extensive environmental and natural resources regulations that impose, and will continue to impose, risks of significant costs and liabilities. In addition, future regulations, or more stringent enforcement of existing regulations, could increase those costs and liabilities, which could adversely affect our results of operations.

We are subject to a variety of federal, state and local environmental laws and regulations affecting the mining and mineral processing industry, including, among others, those relating to environmental permitting and licensing, plant and wildlife protection, wetlands protection, air and water emissions, greenhouse gas emissions, water pollution, waste management, including the transportation and disposal of waste and other materials, remediation of soil and groundwater contamination, land use, reclamation and restoration of properties, hazardous materials and natural resources. These laws and regulations have imposed, and will continue to impose, numerous obligations on our operations and the operations of our customers, including the acquisition of permits or other approvals to conduct regulated activities, the imposition of restrictions on the types, quantities and concentrations of various substances that may be released into the environment or injected in non-productive formations below ground in connection with oil and natural gas drilling and production activities, the incurrence of capital expenditures to mitigate or prevent releases of materials from our equipment or facilities or from customer locations where we are providing services, the imposition of substantial liabilities for pollution resulting from our operations, and the application of specific health and safety criteria addressing worker protection. Some environmental laws impose substantial penalties for noncompliance, and others, such as CERCLA, impose strict, retroactive and joint and several liability for the remediation of releases of hazardous substances.

Further, our business activities present risks of incurring significant environmental costs and liabilities, including costs and liabilities resulting from our handling of oilfield and other wastes, because of air emissions and wastewater discharges related to our operations, and due to historical oilfield industry operations and waste disposal practices. Moreover, accidental releases or spills may occur in the course of our operations or at facilities where our wastes are taken for reclamation or disposal, and we cannot assure you that we will not incur significant costs and liabilities as a result of such releases or spills, including any third-party claims for injuries to persons or damages to properties or natural resources. Remedial costs and other damages arising as a result of environmental laws and costs associated with changes in environmental laws and regulations could be significant and have an adverse effect on our liquidity, results of operations and financial condition.

Additionally, any failure by us or by our customers to comply with applicable environmental laws and regulations may cause governmental authorities to take actions that could adversely impact our operations and financial condition, including:

Moreover, environmental requirements, and the interpretation and enforcement of these requirements, change frequently and have tended to become more stringent over time. Future environmental laws and regulations could restrict our ability to expand our facilities or extract our mineral deposits or could require us to acquire costly equipment or to incur other significant expenses in connection with our business. The costs associated with complying with such requirements could have an adverse effect on our business, financial condition and results of operations. Additionally, our customers may not be able to comply with any new or amended laws and regulations, which could cause our customers to curtail or cease operations and thus reduce demand for our products and services. We cannot at this time reasonably estimate our costs of compliance or the timing of any costs associated with any new or amended laws and regulations, or any material adverse effect that any new or modified standards will have on our customers and, consequently, on our operations.

Our and our customers’ operations are subject to a number of risks arising out of the threat of climate change, including regulatory, political, litigation and financial risks, which could result in increased operating and capital costs for our customers and reduced demand for our products and services.

The threat of climate change continues to attract considerable attention in the United States and around the world. Numerous proposals have been made and could continue to be made at the international, national, regional and state levels of government to monitor and limit existing emissions of GHGs. These efforts have included consideration of cap-and-trade programs, carbon taxes, GHG disclosure obligations and regulations that directly limit GHG emissions from certain sources. As a result, our operations and the operations of our natural gas and crude oil exploration and production customers are subject to a series of regulatory, political, litigation, financial, and physical risks associated with the production and processing of fossil fuels and the emission of GHGs.

Under previous administrations, the EPA has adopted rules that, among other things, establish construction and operating permit reviews for GHG emissions from certain large stationary sources and require the monitoring and annual reporting of GHG emissions from certain industrial sources. However, in February 2026, the EPA issued a final rule rescinding its GHG “Endangerment Finding,” which provides the basis for the EPA’s authority to regulate GHG emissions. Litigation challenging the final rule is likely, and as a result, there is significant uncertainty with respect to regulations related to GHG emissions. We cannot predict the results of any potential legal challenges or the impact of these developments on our business. The EPA has also adopted rules imposing new standards reducing methane emissions from oil and gas operations through limitations on venting and flaring and the implementation of enhanced emission leak detection and repair requirements. The EPA finalized rules in December 2023 that establish new and more stringent standards known as Subparts OOOOa, OOOOb, and OOOOc for the use of emission capture and control equipment and systems, leak detection equipment and monitoring, and so-called “green well completion” requirements for both new and existing sources across the oil and gas sector. However, in March 2025, the EPA announced plans to reconsider Subparts OOOOb and OOOOc and, in November 2025, finalized an interim final rule extending certain compliance deadlines for certain provisions provided in the December 2023 rule. Litigation challenging the interim final rule remains pending. The BLM also finalized a rule on April 10, 2024 intended to curtail the waste of methane flared, vented, or leaked from oil and gas operations on federal and Tribal lands. Various states, including Texas, challenged the rule, and in September 2024, the U.S. District Court for the District of North Dakota enjoined enforcement of the rule against the plaintiff states pending the outcome of litigation, and the BLM announced in December 2025 that it would delay enforcement of certain compliance deadlines under the rule through December 2026.

In addition, the U.S. Congress may continue to consider pass legislation related to the reduction of GHG emissions, including methane and carbon dioxide. Notwithstanding the potential Endangerment Finding repeal, the IRA, which was signed into law in August 2022, appropriates significant incentives for renewable energy initiatives and imposes a fee on GHG emissions from certain facilities in the oil and gas sector. In November 2024, the EPA issued a final rule to implement this emissions charge, although the rule was repealed in March 2025 by a Joint Resolution of Disapproval under the Congressional Review Act, and the EPA subsequently issued a final rule removing it from the Code of Federal Regulations. Additionally, the One Big Beautiful Bill Act, enacted in July 2025, delays implementation of the charge until 2034. We cannot predict if Congress or the Trump administration may take further action to amend, rescind, or otherwise modify the IRA 2022 and its implementing regulations. These regulatory actions, the emissions fee, and funding provisions of the IRA could increase operating costs within the oil and gas industry and accelerate the transition away from fossil fuels, which could in turn reduce demand for our products and services and adversely affect our and our customers’ business and results of operations. We cannot predict whether the current administration’s deregulatory actions will ultimately be successful or if future administrations may seek to re-impose similar requirements.

At the international level, the United Nations-sponsored Paris Agreement, though non-binding, calls for signatory nations to limit their GHG emissions through individually determined reduction goals every five years after 2020. However, on January 20, 2025, President Trump signed an Executive Order once again withdrawing the United States from the Paris Agreement. The United States’ participation in future United Nations climate-related conferences and the impacts of these orders, pledges, agreements and any legislation or regulation promulgated to fulfill the United States’ commitments under the Paris Agreement or other international agreements cannot be predicted at this time.

Litigation risks are also increasing, as a number of cities and other entities have sought to sue various oil and natural gas companies in state or federal court, alleging, among other things, that such companies created public nuisances by producing fuels that contributed to climate change and its effects, such as rising sea levels or extreme weather events, and therefore are responsible for resulting infrastructure damages, or alleging that the companies have been aware of the adverse effects of climate change for some time but defrauded their investors by failing to adequately disclose those impacts. Our customers’ involvement in such a case, regardless of the substance of the allegations, could have adverse reputational impacts and any unfavorable ruling in any such case could significantly impact their operations and consequently could have an adverse impact on demand for our products and services.

There are also increasing financial risks for the oil and gas sector as shareholders, bondholders, and lenders may elect in the future to shift some or all of their investments into non-fossil fuel energy sectors. Certain institutional lenders have shifted their investment practices to favor non-fossil fuel energy sources, such as wind and solar, and some of them may elect not to provide funding to the oil and gas sector. Additionally, there is also a risk that financial institutions will be pressured or required to adopt policies that limit funding for the oil and gas sector, though this trend has waned in recent years. Further, the SEC finalized a rule in March 2024 that establishes a framework for the reporting of climate risks, targets, and metrics. The rule is currently stayed pending litigation, with such litigation held in abeyance until the SEC reconsiders, repeals, or otherwise modifies the rule. In March 2025, the SEC voted to end its defense of the rule, though no further action has been taken at this time to repeal the rule. Relatedly, California has enacted new laws requiring additional disclosure with respect to certain climate-related risks and GHG emissions reduction claims, and New York and other states are considering adopting similar laws. Litigation over these laws is ongoing, and we cannot predict the outcome. Enhanced climate-related disclosure requirements could result in additional legal and accounting costs and accelerate the trend of certain stakeholders and lenders restricting or seeking more stringent conditions with respect to their investments in carbon-intensive sectors. Such disclosure regulations could also lead to increased litigation risks and reputational harm. Any material reduction in the capital available to us or our customers could make it more difficult to secure funding for our growth projects or our customers’ exploration and production activities, which could reduce the demand for our products and services and impact our financial performance.

Finally, physical climate change impacts, including increased frequency and severity of storms, severe and persistent drought conditions, winter storms, floods and other climatic events, may potentially have a large impact on our operations and financial results, and our customers’ exploration and production operations. While our consideration of changing climatic conditions and inclusion of safety factors in the design and operation of our facilities is intended to reduce the uncertainties that climate change and other events may potentially introduce, our ability to mitigate the adverse impacts of these events depends in part on the effectiveness of our disaster preparedness and response and business continuity planning and those of our customers, which may have not considered or prepared for every eventuality.

Restrictions on our operations and those of our customers intended to protect certain species of wildlife could have an adverse impact on our ability to expand some of our existing operations or limit our customers’ ability to develop new oil and natural gas wells.

Various federal and state statutes prohibit certain actions that adversely affect endangered or threatened species and their habitat, migratory birds, wetlands, and natural resources. These statutes include the ESA, the MBTA, the BGEPA and the CWA. The USFWS may designate critical habitat areas that it believes are necessary for survival of threatened or endangered species. A critical habitat designation could result in further material restrictions on federal land use or on private land use and could delay or prohibit land access or development. Where takings of or harm to species or damages to wetlands, habitat, or natural resources occur or may occur, government entities or at times private parties may act to prevent or restrict oil and natural gas exploration activities or seek damages for any injury, whether resulting from drilling or construction or releases of oil, wastes, hazardous substances or other regulated materials, and in some cases, criminal penalties may result.

The DSL is one example of a species that, if listed as endangered or threatened under the ESA, could impact our operations and the operations of our customers. On May 20, 2024, the USFWS finalized a rule listing the DSL as an endangered species under the ESA, but did not concurrently propose to designate any critical habitat. However, in the final rule, USFWS determined that designating DSL critical habitat was prudent, but not determinable at the time of issuance, thus triggering a one-year review period for the future designation of critical habitat. Legal challenges have been filed relating to the listing, and we cannot predict what actions, if any, the Trump administration may take relating to the listing of the DSL as endangered. Our operations and the operations of our customers in any area that is later designated as DSL critical habitat may be limited, delayed or, in some circumstances, prohibited, and we and our customers could be required to comply with expensive mitigation measures intended to protect the DSL and its habitat. However, to mitigate the impact of some of these risks, we are a participant in a CCAA for DSL habitat in non-federal lands in certain counties of western Texas, which was approved by the USFWS in January 2021. We have been a contributor to and supporter of the CCAA since its inception and our participation in the CCAA and our other voluntary conservation measures for the benefit of the DSL, including setting aside as much as 17,000 acres for DSL habitat, helps reduce the risk of disruptions to our business and operations in the event DSL critical habitat is designated in the areas in which we operate.

Another species recently listed that could impact the operations of our customers is the lesser prairie-chicken. In November 2022, the USFWS formally listed two Distinct Population Segments (“DPSs”) of the lesser prairie-chicken under the ESA. The Southern DPS, the habitat of which includes portions of southeast New Mexico and western Texas, was listed as endangered, while the Northern DPS, the habitat of which spans from northern Texas through eastern Oklahoma and into southeastern Colorado and southwestern Nebraska, was listed as threatened. The listed territory of the Southern DPS could overlap with the operating areas of some of our customers, who in turn may be adversely affected by any restrictions which arise as a result of the endangerment determination. However, in August 2025, the U.S. District Court for the Western District of Texas vacated and remanded the final rule listing both DPSs. An appeal of the order is pending. The identification or designation of further previously unprotected species as threatened or endangered or re-listing of the lesser prairie-chicken in areas where we or our customers operate could cause us to incur increased costs arising from species protection measures or could result in limitations on our customers that result in reduced demand for our services, adversely affecting our results of operations. There is also increasing interest from a variety of stakeholders, including investors and institutional lenders, in nature-related matters beyond protected species, such as general biodiversity, which may similarly require us to incur costs or take other measures which may materially impact our business or operations.

Any restrictions on oil and natural gas development on federal lands have the potential to adversely impact our operations and the operations of our customers.

Many of our customers possess leases in New Mexico, which are granted by the federal government and administered by the BLM. Operations conducted by our customers on federal oil and natural gas leases must comply with numerous additional statutory and regulatory restrictions. These leases contain relatively standardized terms requiring compliance with detailed regulations. Under certain circumstances, the BLM may require operations on federal leases to be suspended or terminated. Any such suspension or termination of our customers’ leases could reduce demand for our products or services and adversely impact our results of operations.

The Biden Administration has taken several actions to curtail oil and natural gas activities on federal lands including a temporary pause on new oil and gas leasing, increases in royalty rates, and a reduction in the total acreage available through lease sales. On April 10, 2024, BLM finalized a rule to reduce the waste of natural gas from venting, flaring, and leaks during oil and gas production activities on Federal and Native American leases. Various states, including Texas, challenged the rule, and in September 2024, the U.S. District Court for the District of North Dakota enjoined enforcement of the rule against the plaintiff states pending the outcome of litigation, and the BLM announced in December 2025 that it would delay enforcement of certain compliance deadlines under the rule through December 2026. On April 23, 2024, BLM finalized further reforms to the federal oil and gas leasing program, including increased bonding requirements and the codification of certain IRA provisions related to minimum bids, base rental rates, and royalty rates. While we cannot predict the ultimate impact of these actions or whether the Department of Interior and BLM will implement further reforms or operating restrictions, any revisions to the federal leasing or permitting process that make it more difficult for our customers to pursue operations on federal lands and operate economically may materially adversely impact our operations.

Additionally, oil and natural gas operations on federal lands, and related infrastructure projects may be impacted by recent developments regarding implementation of NEPA. On November 12, 2024, the D.C. Circuit Court concluded that Council on Environmental Quality (“CEQ”) has no authority to issue binding NEPA regulations, and a federal district court in North Dakota reached the same conclusion on February 3, 2025. In February 2025, the CEQ issued an interim final rule rescinding its regulations implementing NEPA and adopted as final the interim final rule in January 2026. In June 2025, several federal agencies issued their own regulations or procedures for implementing NEPA. Further, in May 2025, the Supreme Court held in Seven County Infrastructure Coalition v. Eagle County, Colorado that agency determinations under NEPA are owed substantial judicial deference and that agencies are not obligated to consider environmental effects associated with separate projects. As a result, there is significant uncertainty with respect to the scope of environmental analysis under NEPA, and NEPA procedures currently vary by agency. To the extent changes to or the repeal of the NEPA implementing regulations restrict or limit the ability of our customers to pursue oil and gas operations and development projects in an economical manner or create uncertainty surrounding permitting for these projects, demand for our products and services may be impacted, which could adversely affect our results of operations.

Operations on federal lands also face litigation risks. From time to time, legal challenges have been filed relating to federal leasing decisions or environmental reviews under NEPA, such as for failure to adequately assess the impact of any increase of GHG emissions resulting from increased production on federal lands. Separately, there is a risk that authorizations required for existing operations may be delayed to the point that it causes a business disruption, and we cannot guarantee that further action will not be taken to curtail oil and natural gas development on federal land. For example, certain lawmakers have proposed to reduce or ban further leasing on federal lands or to adopt further restrictions on such leasing. To the extent such legislation is passed, it may adversely impact our customers’ operations, which could negatively impact our financial performance or results of operations.

We and our customers are subject to regulations that impose stringent occupational health, safety and labor standards on numerous aspects of our operations.

Multiple aspects of our and our customers’ operations are subject to occupational health and safety standards, including our mining operations, our trucking operations, and including standards relating to employee exposure to crystalline silica.

Our mining operations are subject to the Mine Safety and Health Act of 1977, as amended by the Mine Improvement and New Emergency Response Act of 2006 (as amended, the “Mine Act”), which imposes stringent health and safety standards on numerous aspects of mineral extraction and processing operations, including the training of personnel, operating procedures, operating equipment and other matters. Our operating locations are regularly inspected by MSHA for compliance with the Mine Act.

The DOT and various state agencies exercise broad powers over our trucking services, generally governing matters including authorization to engage in motor carrier service, equipment operation, safety, alcohol and drug testing, and financial reporting. In addition, our operations must comply with the Fair Labor Standards Act and comparable state laws, which govern such matters as wages and overtime, and which is administered by the DOL or applicable state agencies. We may be audited periodically by the DOT or the DOL or state agencies to ensure that we are in compliance with these safety, hours-of-service, wage and other rules and regulations, and failure to comply could result in material costs.

Our failure to comply with existing or new health and safety standards, or changes in such standards or the interpretation or enforcement thereof, could require us or our customers to modify operations or equipment, shut down some or all operating locations, impose significant restrictions on our ability to conduct operations, impose fines or otherwise have an adverse effect on our business, financial condition, employee relations and results of operations.

We and our customers are subject extensive permitting regulations and obligations. Our or our customers’ failure to obtain, maintain, renew, or comply with the terms of the permits we require to operate may adversely affect our results of operations.

In addition to the regulatory matters described above, we and our customers are subject to extensive permitting obligations and regulations. In order to obtain permits and renewals of permits in the future, we may be required to prepare and present data to governmental authorities pertaining to the potential adverse impact that any proposed excavation or production activities, individually or in the aggregate, may have on the environment. Certain approval procedures may require preparation of archaeological surveys, endangered species studies, and other studies to assess the environmental impact of new sites or the expansion of existing sites. Compliance with these regulatory requirements is expensive and significantly lengthens the time needed to develop a site. Finally, obtaining or renewing required permits is sometimes delayed or prevented due to community opposition and other factors beyond our control.

Our future success depends on, among other things, our ability to extract our proppant deposits profitably, and our customers’ ability to operate their businesses as they currently do. The denial or cancellation of a permit essential to our or our customers’ operations or the imposition of conditions with which it is not practicable or feasible to comply could have an adverse effect on our business. Significant opposition to a permit by neighboring property owners, members of the public or other third parties or a delay in the environmental review and permitting process also could impair or delay our or our customers’ operations. Additionally, new regulations or permitting requirements could require us to modify existing permits or obtain new permits, implement additional pollution control technology, curtail operations (including our ability to extract or the pace of extraction of mineral deposits), significantly increase our operating costs or impose additional operating restrictions among our customers (including impacts that may impact our customers’ ability to use our proppant, logistics or power solutions) that reduce demand for our products or services. Such permit proceedings are often subject to public notice and comment, and third parties, including nongovernmental environmental organizations, may challenge government actions related to permits required for our operations. A failure to timely obtain the permits required for the operation of our business may adversely affect our results of operations.

General Risk Factors

Pandemics, epidemics or disease outbreaks, such as the COVID-19 pandemic, may disrupt our business and operations, which could materially affect our financial condition, results of operations and forward-looking expectations.

Public health crises, pandemics and epidemics, such as the COVID-19 pandemic, may adversely impact our operations, the operations of our customers and the global economy, including the worldwide demand for oil and natural gas and the level of demand for our products and services. Fear of such events has previously altered the level of capital spending by oil and natural gas companies for E&P activities and has adversely affected global economies and financial markets, resulting in economic downturns that have affected demand for our products and services. For instance, the outbreak of COVID-19 caused governmental authorities to impose mandatory closures, seek voluntary closures and impose restrictions on, or advisories with respect to, travel, business operations and public gatherings or interactions. The impact of future health crises, pandemics and epidemics and responsive measures could adversely affect our business in a number of ways, any of which could have a material adverse effect on us.

Our business and operations could suffer in the event of cybersecurity breaches, information and operational technology system failures, network disruptions or other cyber-security risks. A cyber incident could occur and result in information theft, data corruption, operational disruption and/or financial loss.

We rely on the efficient and uninterrupted operation of both our Company’s and third-party information and operational technology systems and infrastructure to process transactions, summarize our operating results, deliver our products, perform many of our services and manage our business and operations. In the ordinary course of our business, we collect and store sensitive data, including our proprietary business information and that of our customers, vendors, suppliers and other business partners, and personally identifiable information of our employees. The secure collection, processing, maintenance, storage, and transmission of information is critical to our operations. We have implemented procedural safeguards and stringent access controls designed to protect our information and operational technology systems and data. Furthermore, we have sophisticated tools and third-party vendors monitoring our networks, email, cloud, and operational technology 24/7 against emerging cyber threats and vulnerabilities. However, our information and operational technology systems and networks, and those of our customers, vendors, suppliers and other business partners, are subject to damage or interruption from power outages, computer and telecommunications failures, computer viruses, cyberattack or other security breaches, catastrophic events, such as fires, floods, earthquakes, tornadoes, hurricanes, acts of war or terrorism, usage errors by our employees and other events unforeseen or generally beyond our control. If our information or operational technology systems are damaged or cease to function properly, we may need to make a significant investment to fix or replace them, and we may suffer loss of critical data, damage to our reputation and financial condition and interruptions or delays in our operations.

We have been the target of cyberattacks, and while to date none of these incidents have had a material impact on us, we expect to continue to be targeted in the future. Cyberattacks are increasing globally in frequency and in sophistication and include, but are not limited to, malicious software, surveillance, credential stuffing, spear phishing, social engineering, use of deepfakes (i.e., highly realistic synthetic media generated by artificial intelligence) attempts to gain unauthorized access to data and systems and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. Our risk and exposure to these matters remains heightened because of, among other things, the evolving nature of these threats, the current global economic and political environment, the outsourcing of some of our business operations, the ongoing shortage of qualified cybersecurity professionals and the interconnectivity and interdependence of third parties to our systems.

As cyber incidents continue to evolve, we will likely be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber incidents. In addition, any technology required by any mandate by authorities requiring the transition to remote work increases our vulnerability to cybersecurity threats, including threats to gain unauthorized access to sensitive information or to render data or systems unusable. Any material disruption in our information or operational technology systems or systems that affect our business operations, delays or difficulties in implementing or integrating new systems or enhancing current systems, or any vulnerabilities rendering data or systems unusable following any mandated remote work situations, could have an adverse effect on our business and results of operations.

We monitor our information and operational technology systems in an effort to detect cyberattacks, security breaches and unauthorized access. Our preventative and detective measures include penetration tests on externally facing systems, threat assessments, cybersecurity audits and expert consultations. However, the measures we employ to detect and prevent cyberattacks may be insufficient to protect us from an incident or to minimize the magnitude and effects of such incident for a significant period of time. Despite our security measures, the occurrence of a cyberattack, breach, unauthorized access, misuse, computer virus or other cybersecurity event could jeopardize our systems, interrupt our operations or result in the unauthorized disclosure, gathering, monitoring, misuse, corruption, loss or destruction of confidential and other information that belongs to us, our customers, our counterparties or third-party service providers that is processed and stored in, and transmitted through, our information technology systems and networks. Any such event could result in significant losses, loss of customers and business opportunities, breaches of our contractual obligations, reputational damage, litigation, regulatory fines, penalties or intervention, reimbursement or other compensatory costs, or otherwise adversely affect our business, financial condition or results of operations. Moreover, the constantly evolving global regulatory landscape surrounding data privacy and cybersecurity poses compliance challenges, and complying with such data protection obligations may be expensive. Any failure, whether real or perceived, by us to comply with applicable data privacy and protection obligations could result in significant losses, loss of customers and business opportunities, breaches of our contractual obligations, reputational damage, litigation, regulatory fines, penalties or intervention, reimbursement or other compensatory costs, or otherwise adversely affect our business, financial condition or results of operations.

We may be unable to generate sufficient cash to service all of our indebtedness and financial commitments.

Our ability to make scheduled payments on or to refinance our indebtedness and financial commitments depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions including financial, business and other factors beyond our control. We may be unable to generate sufficient cash flow to permit us to pay the principal, premium, if any, and interest on our indebtedness.

If our cash flows and capital resources are insufficient to fund debt and other obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital or restructure our indebtedness. Our ability to restructure or refinance indebtedness will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our operations. The terms of existing or future debt instruments may restrict us from adopting some of these alternatives. In addition, any failure to service our debt would likely result in a reduction of our future credit rating, if any, which could harm our ability to incur additional indebtedness. If we face substantial liquidity problems, we might be required to sell assets to meet debt and other obligations. Our debt restricts our ability to dispose of assets and dictates our use of the proceeds from such disposition. We may not be able to consummate dispositions, and the proceeds of any such disposition may be inadequate to meet our obligations.

We may be unable to access adequate funding as a result of a decrease in the borrowing base under the 2023 ABL Credit Facility due to an unwillingness or inability on the part of lending counterparties to meet their funding obligations and the inability of other lenders to provide additional funding to cover a defaulting lender’s portion. As a result, we may be unable to execute our development plan, make acquisitions or otherwise conduct operations, which would have an adverse effect on our financial condition and results of operations.

Changes to applicable tax laws and regulations, exposure to additional income tax liabilities, changes in our effective tax rates or an assessment of taxes resulting from an examination of our income or other tax returns could adversely affect our results of operations and financial condition, including our ability to repay our debt.

We are subject to various complex and evolving U.S. federal, state and local taxes. U.S. federal, state and local tax laws, policies, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us, in each case, possibly with retroactive effect, and may have an adverse effect on our results of operations and financial condition, including our ability to repay our debt. The passage of any tax legislation or other changes in U.S. federal income tax laws could adversely affect our results of operations and financial condition.

Changes in our effective tax rates or tax liabilities could also adversely affect our results of operations and financial condition. Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:

In addition, an adverse outcome arising from an examination of our income or other tax returns could result in higher tax exposure, penalties, interest or other liabilities that could have an adverse effect on our results of operations and financial condition.

Our future tax liabilities may be greater than expected if our net operating loss (“NOL”) are limited.

As of December 31, 2025, we have U.S. federal net operating loss carryforwards of approximately $244.3 million. Utilization of these NOL carryforwards depends on many factors, including our future income, which cannot be assured. In addition, Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), generally imposes an annual limitation on the amount of NOL carryforwards that may be used to offset taxable income when a corporation has undergone an “ownership change” (as determined under Section 382 of the Code). An ownership change generally occurs if one or more stockholders (or groups of stockholders) who are each deemed to own at least 5% of such corporation’s stock change their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. In the event that we were to undergo an ownership change in the future, utilization of our NOL carryforwards would be subject to limitation under Section 382 of the Code. Any unused annual limitation generally may be carried over to later years until they expire. Limitations similar to those applicable under Section 382 of the Code apply for U.S. state income tax purposes. Any limitation on our ability to utilize our NOL carryforwards against income or gain we generate in the future could increase our future tax liabilities and adversely affect our operating results and cash flows.

We are subject to counterparty credit risk. Nonpayment or nonperformance by our customers, suppliers or vendors could have an adverse effect on our business, liquidity, financial condition and results of operations.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers, suppliers and vendors. Our credit procedures and policies may not be adequate to fully eliminate customer credit risk. If we fail to adequately assess the creditworthiness of existing or future customers or unanticipated deterioration in their creditworthiness, any resulting increase in nonpayment or nonperformance by them and our inability to re-market or otherwise use the production could have an adverse effect on our business, results of operations and financial condition. A decline in oil and natural gas prices could negatively impact the financial condition of our customers and sustained lower prices could impact their ability to meet their financial obligations to us. Further, our contract counterparties may not perform or adhere to our existing or future contractual arrangements. To the extent one or more of our contract counterparties is in financial distress or commences bankruptcy proceedings, contracts with these counterparties may be subject to renegotiation or rejection under applicable provisions of the United States Bankruptcy Code. Any material nonpayment or nonperformance by our contract counterparties due to inability or unwillingness to perform or adhere to contractual arrangements could adversely affect our business and results of operations. If our customers delay or fail to pay us a significant amount of our outstanding receivables, it could have an adverse effect on our business, liquidity, financial condition and results of operations.

If we fail to comply with the restrictions and covenants in our debt agreements, there could be an event of default under the terms of such agreements, which could result in an acceleration of payment.

A breach of any representation, warranty or covenant in any of our debt agreements would result in a default under the applicable agreement after any applicable grace periods. A default could result in acceleration of the indebtedness, which would have an adverse effect on us. If an acceleration occurred, it would likely accelerate all of our indebtedness through cross-default provisions and we would likely be unable to make all of the required payments to refinance such indebtedness. Even if new financing were available at that time, it may not be on terms that are acceptable to us.

Our stock prices and trading volumes could be volatile, and you may not be able to resell shares of your Common Stock when desired, at or above the price you paid, or at all.

The stock market has experienced and continues to experience extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the underlying businesses. Recently, market volatility has been high due to the ongoing conflicts between Ukraine and Russia, the Israel-Hamas war, the Israel-Iran conflict, recent events in Venezuela, and other instability in the Middle East, including from the Houthi rebels in Yemen, interest rate increases, rising inflation, instability of the banking sector, a softening U.S. economy and other factors. Broad market fluctuations may adversely affect the market price of the Common Stock, regardless of our actual operating performance. In addition to the other risks described in this section, the market price of our Common Stock may fluctuate significantly in response to a number of factors, many of which we cannot control, including:

Volatility in the market price or trading volume of the Common Stock may make it difficult or impossible for you to sell your Common Stock at or above the price at which you purchased the stock. As a result, you may suffer a loss on your investment. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. This litigation, if instituted against us, could result in substantial costs, reduce our profits, divert our management’s attention and resources and harm our business.

If securities or industry analysts do not publish research or reports or publish unfavorable research about us, the price and trading volume of our Common Stock could decline.

The trading market for our Common Stock depends in part on the research and reports that securities or industry analysts publish about us and our business. If one or more of the analysts who covers us downgrades our securities, the price of our securities would likely decline. If one or more of these analysts ceases to cover us or fails to publish regular reports on us, interest in the purchase of our securities could decrease, which could cause the price of our Common Stock and other securities and their trading volume to decline.

Item 2. Properties.

We currently operate our Kermit facilities, Monahans facility, and OnCore distributed mining network in West Texas. For the years ended December 31, 2025 and 2024, we produced, in aggregate, approximately 21.6 million tons and 19.9 million tons of proppant, respectively, inclusive of the production attributable to the assets acquired in the Hi-Crush Transaction during 2024. For the year ended December 31, 2023, our facilities produced, in aggregate, approximately 11.0 million tons. The following map shows the location of these facilities:

Kermit, Texas

K1/K2 Facilities

The Kermit property in the map below includes K1/K2. This map can be found in Section 1.3 of our 2023 TRS (defined below) prepared by JT Boyd, which is included as Exhibit 96.1 to this Annual Report.

Our K1/K2 facilities are located on 5,826 gross acres of land (of which 5,341 net acres are controlled by us either through lease or fee ownership) in Winkler County, Texas, with onsite processing and truck loading facilities. We commenced construction of our first mine in October of 2017, and commenced operations in June 2018. We commenced construction of our second mine in July of 2022, which we completed in December 2023. Our K1/K2 facilities have a net book value of $410.2 million as of December 31, 2025. Geographically, our facilities are located at approximately 31° 58’ 6.29” N latitude and 103° 0’ 39.46” W longitude, are situated approximately seven miles northeast of Kermit, Texas, and are accessible via Texas State Highway 18. The Midland International Air and Space Port is located approximately 45 miles southeast of the facilities.

The K1/K2 facilities have 286.4 million tons of associated proven reserves as of December 31, 2025. The sand deposits generally range from 60 to over 100 feet thick and consist of 40/70-mesh and 100-mesh sand, with an anticipated production mix of approximately 53% 40/70-mesh and approximately 47% 100-mesh. The crush strength of the sand mined at these facilities is between 7,000 to 8,000 pounds-per-square-inch (“PSI”) for 40/70-mesh and between 10,000 to 11,000 PSI for 100-mesh.

We lease a portion of the mineral reserves and resources associated with our K1/K2 facilities. As of December 31, 2025, we owned approximately 43% and 2% of our mineral reserves and resources, respectively, and leased approximately 57% and 98% of our mineral reserves and resources, respectively, from third-party landowners at our K1/K2 facilities.

In December 2017, we entered into a royalty agreement with Sealy Smith. The royalty agreement associated with the K1/K2 facilities terminated on the date of our IPO, pursuant to the terms of the agreement.

K115/874 Facilities

The Kermit property in the map below includes K115/874. This map can be found in Section 1.2 of our 2023 TRS (defined below) prepared by JT Boyd, which is included as Exhibit 96.2 to this Annual Report.

During 2024, we acquired the K115/874 facilities with the Hi-Crush Transaction. Our K115/874 facilities are located on approximately 1,226 gross acres of surface and subsurface (i.e., mineral) rights, all of which are owned by the Company. Our K115/874 facilities have a net book value of $160.0 million as of December 31, 2025. Geographically, these facilities are located at approximately 31° 57' 55" N latitude and 102° 58' 15" W longitude and are accessible via Texas State Highway 115. Several regional airports are located within an hour’s drive from the mine, and the Midland International Airport is approximately an hour and a half away by road.

The K115/874 facilities were initially explored and developed by Permian Basin Sand Company, LLC in 2016 and Hi-Crush purchased this property in early 2017. Site work and construction for the first processing facility began in February 2017 and was commissioned in July 2017. Construction of the second processing facility began in May 2018 and was fully commissioned and producing finished frac sand by January 2019.

The K115/874 facilities have 50.5 million tons of associated proven reserves as of December 31, 2025. The sand deposits generally range from 10 to over 90 feet thick, averaging approximately 60 feet across the property and consist of 100-mesh sand. The crush strength of the sand mined at these facilities is 7,000 PSI for 40/70-mesh and 12,000 PSI for 100-mesh.

Monahans, Texas

This map can be found in Section 1.3 of our 2023 TRS (defined below) prepared by JT Boyd, which is included as Exhibit 96.1 to this Annual Report.

Our Monahans facility is located on approximately 32,224 gross acres of land in Ward County, Texas, with onsite processing and truck loading facilities. We commenced construction of our Monahans mine in February of 2018 and commenced operations in October 2018. Our Monahans facility has a net book value of $201.0 million as of December 31, 2025. Geographically, our Monahans facility is located at approximately 31° 39’ 32.53” N latitude and 102° 52’ 55.46” W longitude, is situated approximately three miles northeast of Monahans, Texas, and is accessible via Texas State Highway 115 and Interstate 20. The Midland International Air and Space Port is located approximated 40 miles east of the facility.

The Monahans facility has 138.7 million tons of associated proven reserves as of December 31, 2025. The sand deposits generally range from 60 to over 100 feet thick and consist of 40/70-mesh and 100-mesh sand, with an anticipated production mix of approximately 64% 40/70-mesh and approximately 36% 100-mesh. The crush strength of the sand mined at the facility is 7,000 to 8,000 PSI for 40/70-mesh and between 10,000 to 11,000 PSI for 100-mesh.

As of December 31, 2025, we lease all of the mineral reserves and resources associated with our Monahans facilities.

The rights and access to the mineral reserves associated with our Monahans operations are secured under a lease agreement (the “Monahans Lease”) with Sealy Smith. Under the Monahans Lease, 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.

OnCore Distributed Mining Network

This map can be found in Section 1.2 of our 2024 TRS (defined below) prepared by JT Boyd, which is included as Exhibit 96.3 to this Annual Report.

During 2024, we acquired the OnCore distributed mining network with the Hi-Crush Transaction. The OnCore sites comprise approximately 6,579 acres, including 1,172.4 acres owned in fee and 5,406.6 leased acres. The OnCore sites are primarily operated under lease agreements held between the Company and various private landowners. These agreements provide the Company the right to mine, process, and dispose (i.e., sell) of frac sand from the properties. The OnCore distributed mining network has a net book value of $94.8 million as of December 31, 2025. The OnCore Plants are located in West Texas. Most are clustered around the City of Big Spring, Texas, about 40 miles east of the Midland-Odessa metropolitan area. The OnCore 7 and 9 sites are located in the opposite direction approximately 90 miles west of Midland-Odessa.

The locations of operating and idled OnCore plants are shown in the table below.

Accessibility to the western sites is via Texas state highway TX-302 or U.S. Route 285; while primary access to the eastern sites is via Interstate 20, state highways TX-137, TX-176, or TX-349. Several regional airports are located throughout the area, and the Midland International Airport is just over two-hours drive from the farthest OnCore location by road.

The OnCore distributed mining network was developed after completing a series of regional geologic exploration efforts across areas located outside of the historic Permian Basin frac sand mining activity centers. The first OnCore site opened in late-2020, and after seeing continued demand for locally sourced damp frac sand, there are now a total of 9 different producing OnCore sites.

The status of each site is provided in the table below.

The OnCore distributed mining network has 29.5 million tons of associated proven reserves as of December 31, 2025. The sand deposits generally range from less than 5 to over 40 feet thick and consist of 100-mesh. The crush strength of the sand mined at the facility is 7,000 to 13,000 PSI for 100-mesh.

Our Reserves

Information concerning our material mining properties in this Annual Report has been prepared in accordance with the requirements of Subpart 1300 of Regulation S-K, which first became applicable to us for the fiscal year ended December 31, 2023. As used in this Annual Report, the terms “mineral resource,” “mineral reserve,” “proven mineral reserve” and “probable mineral reserve” are defined and used in accordance with Subpart 1300 of Regulation S-K.

We categorize our mineral reserves as proven or probable based on the standards set by our independent mining engineers and geologists, JT Boyd. We estimate that we had a total of approximately 571.3 million tons of proven and probable mineral reserves as of December 31, 2025. As of December 31, 2025, we had approximately 286.4 million tons of proven mineral reserves and 36.8 million tons of probable recoverable mineral reserves associated with our K1/K2 facilities, approximately 50.5 million tons of proven mineral reserves and 3.9 million tons of probable recoverable mineral reserves associated with our K115/874 facilities, approximately 138.7 million tons of proven mineral reserves and 2.2 million tons of probable recoverable mineral reserves associated with our Monahans facility, and approximately 29.5 million tons of proven mineral reserves and 23.3 million tons of probable recoverable mineral reserves associated with our OnCore distributed mining network. The quantity and nature of the mineral reserves at each of our properties are estimated by our internal geology department. We use drone surveys and three-dimensional models to regularly update our reserve estimates, making necessary adjustments for operations and mine plans at each location during the year.
