Atlas Energy Solutions Inc. (AESI) Business

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.

11

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:

12

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.

13

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.

15

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.

16

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.

17

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.

18

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.
