PART I
Item 1.     Business.
Our Company
We are a leading integrated oilfield service company, located in Midland, Texas‑based oilfield services companyTexas, focused on providing innovative hydraulic fracturing, wireline, and other complementary oilfield completion services to leading upstream oil and gas companies engaged in the exploration and production ("E&P")&P of North American oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated longstanding customer relationships with some of the region’s most active and well‑capitalized E&P companies. The Permian Basin is widely regarded as one of the most prolific oil‑producing areas in the United States, and we believe we are one of the leading providers of hydraulic fracturingcompletion services in the region by hydraulic horsepower ("HHP").region.
       Our total available HHP at December 31, 2021 was 1,423,000 HHP,On November 1, 2022, we consummated the acquisition of all of the outstanding limited liability company interests of Silvertip Completion Services Operating, LLC (the "Silvertip Acquisition"), which was comprised of 90,000 HHPprovides wireline perforation and ancillary services solely in the Permian Basin in exchange for 10.1 million shares of our Tier IV Dynamic Gas Blending ("DGB") equipment, 1,225,000 HHPcommon stock valued at $106.7 million, $30.0 million of conventional Tier II equipmentcash, the payoff of $7.2 million of assumed debt, and 108,000 HHPthe payment of our DuraStim®electric hydraulic fracturing equipment. Our fleet could range from approximately 50,000 to 80,000 HHP depending oncertain other closing and transaction costs. The Silvertip Acquisition positioned the job designCompany as a more integrated and customer demand at the wellsites. With the industry transition to lower emissions equipment and simultaneous hydraulic fracturing ("Simul-Frac"), in addition to several other changes to our customers' job designs, we believe that our available fleet capacity could decline if we decide to reconfigure our fleets to increase active HHP and backup HHP at the wellsites. In September 2021, we placed an order with our equipment manufacturers for 125,000 HHP of Tier IV DGB equipment for additional conversions, which we expect to be delivered at different times through the first half of 2022.
          In 2019, we entered into a purchase commitment for 108,000 HHP of DuraStim® electric powered hydraulic fracturing equipment. In addition to DuraStim® fleets, we are also evaluating other electric and alternative pressure pumping solutions. In December 2021, we disposed of our two gas turbines initially purchased to provide electrical power to our DuraStim® fleets as we determined they were an inefficient power solutiondiversified completions-focused oilfield service provider headquartered in the field. In Permian Basin.
On December 1, 2023, we consummated the future, we may lease electrical power equipment from a third party or rely onpurchase of the assets and operations of Par Five Energy Services LLC (“Par Five”), which provides cementing services in the Delaware Basin in exchange for $25.4 million of cash. Par Five’s business complements our customersexisting cementing business and enables us to provide power solutions for our electric equipment.serve both the Midland and Delaware Basins of the Permian Basin.
Our competitors include many large and small oilfield servicesservice companies, including Halliburton Company, Liberty Oilfield Services Inc., Nextier Oilfield SolutionsEnergy Inc., Patterson-UTI Energy Inc., ProFrac Holding Corp., RPC, Inc., FTS International Inc. and a number of private and locally-oriented businesses. The markets in which we operate are highly competitive. To be successful, an oilfield servicesservice company must provide services that meet the specific needs of oil and natural gas E&P companies at competitive prices. Competitive factors impacting sales of our services are price, reputation, technical expertise, emissions profile, service and equipment design and quality, and health and safety standards. Although we believe our customers consider all of these factors, we believe price is a key factor in E&P companies' criteria in choosing a service provider. However, we have recently observed the energy industry and our customers shift to lower emissions equipment, which we believe will be an increasingly important factor in an E&P company's selection of a service provider. The transition to lower emissions equipment has been challenging for companies in the service industry because of the capital requirements, lack of large scale deployment of certain new technology such as electric-powered equipment, and the depressed pricing experienced by the service industry.for our services and expected return on invested capital. While we seek to price our services competitively, we believe many of our customers elect to work with us based on our operational efficiencies, productivity, equipment quality, reliability, ability to manage multifaceted logistics challenges, commitment to safety and the ability of our people to handle the most complex Permian Basin well completions.
Our substantial market presence in the Permian Basin positions us well to capitalize on drilling and completion activity in the region. Primarily, ourOur operational focus has primarily been in the Permian Basin's Midland sub-basin, where our customers have operated. However, we have recently increased our operations in the Delaware sub-basin and are well-positioned to support further increases to our activity in this area in response to demand from our customers. Over time, we expect the Permian Basin's Midland and Delaware sub-basins to continue to command a disproportionate share of future North American E&P spending.
Through our pressure pumping segment (which also includes our cementing operations), weWe primarily provide hydraulic fracturing, wireline, and cementing completion services to E&P companies in the Permian Basin. Our hydraulic fracturing fleetequipment has been designed to handle the operating conditions commonly utilizedencountered in the Permian Basin and the region's increasingly high-intensity well completions (including Simul-Frac,simultaneous hydraulic fracturing (“Simul-Frac”), which involves fracturing multiple wellbores at the same time), which are characterized by longer horizontal wellbores, more stages per lateral and increasing amounts of proppant per well.
Effective September 1, 2022, we disposed of our coiled tubing assets to STEP Energy Services Ltd. ("STEP") and shut down our coiled tubing operations. We received approximately $2.8 million in cash and 2.6 million common shares of STEP, valued at $11.8 million, as consideration. Upon the sale of our coiled tubing assets, we recorded a loss on sale of $13.8 million.

          In addition to our core pressure pumping segment operations, which includes our cementing operations, we also offer coiled tubing services. Through our coiled tubing services segment, we seek to create operational efficiencies for our customers, which could allow us to capture a greater portion of their capital spending across the lifecycle of a well.
Commodity Price and Other Economic Conditions
The oil and gas industry has traditionally been volatile and is influencedcharacterized by a combination of long-term, short-term and cyclical trends, including domestic and international supply and demand for oil and gas, current and expected future prices for oil and gas and the perceived stability and sustainability of those prices, and capital investments of E&P companies toward their development and production of oil and gas reserves. The oil and gas industry is also impacted by general domestic and international economic conditions such as supply chain disruptions and inflation, war and political instability in oil producing countries, government regulations (both in the United States and internationally), levels of consumer demand, adverse weather conditions, and other factors that are beyond our control.
Since October 2023, an ongoing conflict between Israel and Palestinian militants in the Israel-Gaza region has led to significant armed hostilities. The global public health crisisgeopolitical and macroeconomic consequences of this conflict remain uncertain, and such events, or any further hostilities in the Israel-Gaza region or elsewhere, could severely impact the world economy, the demand for and price of crude oil and the oil and gas industry generally and may adversely affect our financial condition.
Similarly, the geopolitical and macroeconomic consequences of the Russian invasion of Ukraine, including the associated withsanctions, and the adverse impacts of the COVID-19 pandemic could continuein recent years have resulted in volatility in supply and demand dynamics for crude oil and associated volatility in crude oil pricing. As the global response to have an adverse effect on global economic activitythe COVID-19 pandemic began to wane, the demand and prices for crude oil increased from the foreseeable future. Somelows experienced in 2020, with the West Texas Intermediate (“WTI”) average crude oil price reaching approximately $94 per barrel in 2022, the highest average price in the prior nine years. However, in 2023, the WTI average crude oil price declined to approximately $78 per barrel. We believe that the volatility of the challengescrude oil prices in recent years has been partly driven by declines in crude oil supplies, concerns over sanctions resulting from Russia's invasion of Ukraine, concerns over a potential disruption of Middle Eastern oil supplies resulting from the COVID-19 pandemic that have impacted our business include restrictions on movement of personnelongoing conflict between Israel and associated gatherings, shortage of skilled labor, cost inflation and supply chain disruptions. Additionally, with most of the large, capitalized E&P companiesPalestinian militants in the United States, including our customers, closely managing their operating budget and exercising capital discipline, we do not currently expect significant increases inIsrael-Gaza region, slower crude oil production overgrowth due to the short-to-medium term. Furthermore,lack of reinvestment in the oil and gas industry in the last two years, recent OPEC+ has indicated that they will continue with their plans to manage production levels by gradually increasingcuts of approximately 1.3 million barrels per day and concerns of a potential global recession resulting from high inflation and interest rates.
With the significant increase in global crude oil output. Withprices from 2021, including the tightness inWTI crude oil production and growing demand for crude oil,price, there has beenwas a significant increase in rig count and WTI crude oil prices have increased to over $90 per barrel in February 2022 from its lowest point of $20 per barrel in March 2020. Thethe Permian Basin rig count has increased significantly from approximately 179 at the beginning of 2021 to approximately 294353 at the end of 2021,2022, according to the Baker Hughes. AlthoughHughes Company (“Baker Hughes”). Following the increase in rig count and the WTI crude oil price, the oilfield service industry has experienced increased demand for its completion services, and improved pricing. However, we have recently experienced a 13% decrease in the rig count in 2023 to 309 at the end of 2023 which resulted in a reduction in the demand for completion services and pressure on pricing of our services.

Sustained levels of high inflation have likewise caused the U.S. Federal Reserve and other central banks to increase interest rates, and to the extent elevated inflation remains, we may experience further cost increases for our operations, including interest rates, labor costs and equipment. We cannot predict any future trends in the rate of inflation and crude oil prices. A significant increase in or continued high levels of inflation, to the extent we are unable to timely pass-through the cost increases to our customers, or further declines in crude oil prices are currently at a 7-year high,would negatively impact our business, financial condition and results of operations. See Part II, Item 1A. "Risk Factors—We may be adversely affected by the oilfield services industry, including the pressure pumping segment, has not fully recovered as evidenced by continued depressed pricing for mosteffects of our services, and shortages of skilled labor force in the Permian Basin, coupled with rising inflationary costs. However, we still believe that the Permian Basin, our primary area of operation, will be the most attractive basin to E&P companies and should command higher prices and associated profitability, if the overall demand for crude oil and our services continues to increase.inflation."
Government regulations and investors are demanding the oil and gas industry transition to a lower emissions operating environment, including the upstream and oilfield servicesservice companies. As a result, we are working with our customers and equipment manufacturers to transition our equipment to a lower emissions profile. Currently, a number of lower emission solutions for pumping equipment, including Tier IV DGB dual-fuel, FORCESM electric, direct drive gas turbine and other technologies have been developed, and we expect additional lower emission solutions will be developed in the future. We are continually evaluating these technologies and other investment and acquisition opportunities that would support our existing and new customer relationships. The transition to lower emissions equipment is quickly evolving and will be capital intensive. Over time, we may be required to convert substantially all of our conventional Tier II equipment to lower emissions equipment. IfWe have transitioned our hydraulic fracturing available equipment portfolio from approximately 10% lower emissions equipment in 2021 to approximately 35% in 2022 and 60% in 2023, and expect to increase to approximately 65% by the end of the first half of 2024. To the extent any of our customers have certain expectations or requirements with respect to emissions reductions from their contractors, if we are unable to continue quickly transitiontransitioning to lower emissions equipment, and meet our and our customers’ emissions goals, the demand for our services could be adversely impacted.
          The
If the Permian Basin rig count increase, WTI crude oil price increase and costs inflation could be indicative of an energy market recovery. If the rig count and market conditions continue to improve, including improved customers' pricing for our services and labor availability, and we are able to meet our customers' lower emissions equipment demands, we believe our operational and financial results will also continue to improve.

An individual fleet could range from approximately 50,000 to 80,000 HHP depending on the job design and 108,000 HHPcustomer demand at the wellsite. of our DuraStim® hydraulic fracturing equipment. OurDuraStim® hydraulic fracturing equipment has been tested on a limited scale basis with certaindesigned to handle the operating conditions commonly encountered in the Permian Basin and the region’s increasingly high-intensity well completions (including Simul-Frac, which involves fracturing multiple wellbores at the same time), which are characterized by longer horizontal wellbores, more stages per lateral and increasing amounts of proppant per well. With the industry transition to lower emissions equipment and Simul-Frac, in addition to several other changes to our customers' job designs, we believe that our available fleet capacity could decline if we decide to reconfigure our fleets to increase active HHP and backup HHP at wellsites. In addition, in 2021 and 2022, we committed to additional conversions of our Tier II equipment to Tier IV DGB dual-fuel equipment, and to purchase new Tier IV DGB dual-fuel equipment. As such, we entered into conversion and purchase agreements with our equipment manufacturers for a total of 452,500 HHP of Tier IV DGB dual-fuel equipment and as of December 31, 2023, we have received all of the converted and new Tier IV DGB dual-fuel equipment. In 2022, we entered into three-year electric fleet leases for a total of four FORCESM electric-powered hydraulic fracturing fleets with 60,000 HHP per fleet. As of December 31, 2023, we have received 144,000 HHP of FORCESM electric-powered equipment. We currently expect to receive the remaining equipment associated with the second and third fleets and all equipment associated with the fourth fleet in the first half of 2024. We have entered into contracts with customers and we are evaluatingfor the appropriate strategyuse of two of our FORCESM electric-powered hydraulic fracturing fleets to continue such field testing, including whether field testing will be conducted in 2022.provide committed services for a period of up to three years.
The hydraulic fracturing process consists of pumping a fracturing fluid into a well at sufficient pressure to fracture the formation. Materials known as proppants, which in our business are comprised primarily of sand, are suspended in the fracturing fluid and are pumped into the fracture to prop it open. The fracturing fluid is designed to break, or loosen viscosity, and be forced out of the formation by its pressure, leaving the proppants suspended in the fractures created, thereby increasing the mobility of the hydrocarbons. As a result of the fracturing process, production rates are usually enhanced substantially, thus increasing the rate of return of hydrocarbons for the operator.
We own and operate a fleet of mobile hydraulic fracturing units and other auxiliary equipment to perform fracturing services. We also refer to all of our fracturing units, other equipment and vehicles necessary to perform a fracturing job as a "fleet""fleet" and the personnel assigned to each fleet as a "crew."crew." On average, one hydraulic fracturing fleet consists of approximately 50,000 to 80,000 HHP, depending on job design and customer demand. Our hydraulic fracturing units consist primarily of a high pressure hydraulic pump,pumps, diesel or dual gas engine, transmissionengines, transmissions and various hoses, valves, tanks and other supporting equipment like blenders, irons, hoses and datavans. Our

DuraStim® hydraulic fracturing fleet is electrically driven and can be powered by turbines, generators or similar equipment that can generate electricity. In December 2021, we sold our two turbines for cash consideration of $36.0 million, and the net book value of the turbines prior to the sale was approximately $39.5 million. Our two turbines were initially purchased to provide power to our DuraStim® equipment. In the future, we may lease or purchase alternative power solutions for our electric equipment.

We provide dedicated equipment, personnel and services that are tailored to meet each of our customer’s needs. Each fleet has a designated team of personnel, which allows us to provide responsive and customized services, such as project design, proppant and other consumables procurement, real‑timereal-time data provision and post‑completion analysis for each of our jobs. Many of our hydraulic fracturing fleets and associated personnel have worked continuously with the same customer for the past several years promoting deep relationships and a high degree of coordination and visibility into future customer activity levels. Furthermore, in light of our substantial market presence and historically high fleet utilization levels, we have established a variety of trusted relationships with key equipment, sand and other downhole consumable suppliers. We believe these strategic relationships position us to acquire equipment, parts and materials on a timely and economic basis and allow our dedicated procurement and logistics team to support consistently safe and reliable operations.
Wireline
We provide wireline and ancillary services on new oil well completions in the Permian Basin. Wireline utilizes equipment with a drum of wireline to deploy perforating guns in the well to perforate the casing, cement, and formation. Once the well is perforated, it is ready to be fractured. Pumpdown utilizes pressure pumping equipment to pump water into the well to deploy or push the perforating guns attached to the wireline through the lateral section of a well.
We own and operate a fleet of mobile wireline units and other auxiliary equipment to perform well completion services. We also refer to our wireline units, pressure control equipment, other equipment and vehicles necessary to perform a job as a "spread" and the personnel assigned to the spread as a "crew." On average, one wireline spread consists of a wireline tractor truck with a large cab functioning as a mobile office where the engineer controls the wireline spooled drum along with associated pressure control iron and equipment, trailers and vehicles. We currently have 23 wireline units.
Cementing
We provide cementing services for completion of new wells and remedial work on existing wells. Cementing services use pressure pumping equipment to deliver a slurry of liquid cement that is pumped down a well between the casing and the borehole. Cementing provides isolation between fluid zones behind the casing to minimize potential damage to hydrocarbon bearing formations or the integrity of freshwater aquifers, and provides structural integrity for the casing by securing it to the earth. Cementing is also done when re-completing wells, where one zone is plugged and another is opened.
We believe that our cementing segment provides an organic growth opportunity for us to expand our service offerings within our existing customer base.

We currently have
Other Services
Coiled Tubing
          Coiled tubing services involve injecting coiled tubing into wells to perform various completion well intervention operations. Coiled tubing is a flexible steel pipe with a diameter of typically less than three inches and manufactured in continuous lengths of thousands of feet. It is wound or coiled on a truck‑mounted reel for onshore applications. Due to its small diameter, coiled tubing can be inserted into existing production tubing and used to perform a variety of services (including drillout of plugs) to enhance the flow of oil or natural gas.
          The principal advantages of using coiled tubing include the ability to (i) continue production from the well without interruption, thus reducing the risk of formation damage, (ii) move continuous coiled tubing in and out of a well significantly faster than conventional pipe used with a workover rig, which must be jointed and unjointed, (iii) direct fluids into a wellbore with more precision, allowing for improved stimulation fluid placement, (iv) provide a source of energy to power a downhole motor or manipulate downhole40 tools, and (v) enhance access to remote fields due to the smaller size and mobility.cementing units.
Our Customers
Our customers consist primarily of oil and natural gas producers in North America. Our top five customers accounted for approximatelyapproximately 63.2%, 84.0% and 85.7%, 86.5% and 77.1% of our revenue, for the years ended December 31, 2021, 20202023, 2022 and 2019,2021, respectively. For the year ended December 31, 2021, Pioneer Natural Resources USA Inc. ("Pioneer") and2023, Endeavor Energy Resources and XTO Energy accounted for 54.2% 19.7% and 14.6%18.2%, respectively, of total revenue. No other customer accounted for more than 10% of our total revenue for the year ended December 31, 2021.2023. There have been many recent mergers and acquisitions in the oil and gas industry. In October 2023, Pioneer Natural Resources USA, Inc. (“Pioneer”) entered into a merger agreement with Exxon Mobil Corporation. Mergers and acquisitions involving our customers could negatively impact our future business with them or positively impact our business by providing us access to potential new customers.
On March 31, 2022, we entered into an amended and restated pressure pumping services agreement (the "A&R Pressure Pumping Services Agreement") with Pioneer, which was initially entered into in connection with our purchase of certain pressure pumping assets and real property from Pioneer and Pioneer Pumping Services, LLC (the "Pioneer Pressure Pumping Acquisition"). The A&R Pressure Pumping Services Agreement expired at the conclusion of its term and was replaced by the Fleet One Agreement and the Fleet Two Agreement described below.
On October 31, 2022, we entered into two pressure pumping services agreements (the “Fleet One Agreement” and “Fleet Two Agreement”) with Pioneer, pursuant to which we provided hydraulic fracturing services with two committed fleets, subject to certain termination and release rights. The Fleet One Agreement was effective as of January 1, 2023 and was terminated on August 31, 2023. The Fleet Two Agreement was effective as of January 1, 2023 and was terminated on May 12, 2023.

Competition
The markets in which we operate are highly competitive. To be successful, an oilfield servicesservice company must provide services and equipment that meet the specific needs of oil and natural gas E&P companies at competitive prices. Competitive factors impacting sales of our services are price, reputation, technical expertise, emissions profile, service and equipment design and quality, and health and safety standards. Although we believe our customers consider all of these factors, we believe price is a key factor in E&P companies’ criteria in choosing a service provider. However, we have recently observed the energy industry and our customers shift to lower emissions equipment, which we believe will be an increasingly important factor in an E&P company’s selection of a service provider. The transition to lower emissions equipment has been challenging for companies in the oilfield service industry because of the capital requirements and the continuing depressed pricing experienced by the service industry.requirements. While we seek to price our services competitively, we believe many of our customers elect to work with us based on our operational efficiencies, productivity, equipment portfolio and quality, reliability, ability to manage multifaceted logistics challenges, commitment to safety and the ability of our people to handle the most complex Permian Basin well completions.
We provide our services primarily in the Permian Basin, and we compete against different companies in each service and product line we offer. Our competition includes many large and small oilfield servicesservice companies, including the largest integrated oilfield servicesservice companies. Our major competitors for hydraulic fracturing services include Halliburton Company, Liberty Oilfield Services Inc., Nextier Oilfield SolutionsEnergy Inc., Patterson‑UTI Energy Inc., ProFrac Holding Corp., RPC, Inc., FTS International, Inc. and a number of private and locally-oriented businesses.
Seasonality
Our results of operations have historically reflected seasonal tendencies, generally in the fourth quarter, relating to the conclusion of our customers’ annual capital expenditure budgets, the holidays and inclement winter weather during which we may experience declines in our operating and financial results.
Operating Risks and Insurance
Our operations are subject to hazards inherent in the oilfield servicesservice industry, such as accidents, blowouts, explosions, fires and spills and releases that can cause personal injury or loss of life, damage or destruction of property, equipment, natural resources and the environment and suspension of operations.
4


In addition, claims for loss of oil and natural gas production and damage to formations can occur in the oilfield servicesservice industry. If a serious accident were to occur at a location where our equipment and services are being used, it could result in us being named as a defendant in lawsuits asserting large claims.
Our business involves the transportation of heavy equipment and materials, and as a result, we may also experience traffic accidents which may result in spills, property damage and personal injury.
Despite our efforts to maintain safety standards, we have suffered accidents from time to time in the past and anticipate that we could experience accidents in the future. In addition to the property damage, personal injury and other losses from these accidents, the frequency and severity of these incidents affect our operating costs and insurability and our relationships with customers, employees, regulatory agencies and other parties. Any significant increase in the frequency or severity of these incidents, or the general level of compensation awards, could adversely affect the cost of, or our ability to obtain workers’ compensation and other forms of insurance, and could have other material adverse effects on our financial condition and results of operations.
We maintain commercial general liability, workers’ compensation, business automobile, commercial property, umbrella liability, excess liability, and directors and officers insurance policies providing coverages of risks and amounts that we believe to be customary in our industry. Further, we have pollution legal liability coverage for our business entities, which would cover, among other things, third party liability and costs of clean up relating to environmental contamination on our premises while our equipment is in transit and on our customers’ job site. With respect to our hydraulic fracturing operations, coverage would be available under our pollution legal liability policy for any surface or subsurface environmental clean‑upcleanup and liability to third parties arising from any surface or subsurface contamination. We also have certain specific coverages for some of our businesses, including our hydraulic fracturing and wireline services.
We maintain directors and officers insurance; however, our insurance coverage is subject to certain exclusions (including, for example, any required SECUnited States Securities and Exchange Commission (“SEC”) disgorgement or penalties) and we are
5



responsible for meeting certain deductibles under the policies. Moreover, we cannot assure you that our insurance coverage will adequately protect us from claims made in the Logan Lawsuit or anyall future claims.
Although we maintain insurance coverage of types and amounts that we believe to be customary in the industry, we are not fully insured against all risks, either because insurance is not available or because of the high premium costs relative to perceived risk. Further, insurance rates have in the past been subject to wide fluctuation and changes in coverage could result in less coverage, increases in cost or higher deductibles and retentions. Liabilities for which we are not insured, or which exceed the policy limits of our applicable insurance, could have a material adverse effect on us. See “Risk Factors”"Risk Factors" for a description of certain risks associated with our insurance policies.
Environmental and Occupational Health and Safety Regulations
Our operations are subject to stringent laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection, and occupational health and safety. Numerous federal, state and local governmental agencies issue regulations that often require difficult and costly compliance measures that could carry substantial administrative, civil and criminal penalties and may result in injunctive obligations for non-compliance. These laws and regulations may, for example, restrict the types, quantities and concentrations of various substances that can be released into the environment, limit or prohibit construction or drilling activities on certain lands lying within wilderness, wetlands, ecologically or seismically sensitive areas and other protected areas, or require action to prevent or remediate pollution from current or former operations. Moreover, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or other waste products into the environment. Changes in environmental, health and safety laws and regulations occur frequently, and any changes that result in more stringent and costly requirements could materially adversely affect our operations and financial position. For example, following the electionpassage of President Biden and Democratic control in both houses of Congress,laws such as the IRA 2022, it is possible that our operations may be subject to greater environmental, health and safety restrictions, particularly with regards to hydraulic fracturing and wireline, permitting and greenhouse gases ("GHG") emissions. We have not experienced any material adverse effect from compliance with current requirements; however, this trend may not continue in the future.
Below is an overview of some of the more significant environmental, health and safety requirements with which we must comply. Our customers’ operations are subject to similar laws and regulations. Any material adverse effect of these laws and regulations on our customers’ operations and financial position may also have an indirect material adverse effect on our operations and financial position.

Waste Handling. We handle, transport, store and dispose of wastes that are subject to the Resource Conservation and Recovery Act ("RCRA") and comparable state laws and regulations, which affect our activities by imposing requirements regarding the generation, transportation, treatment, storage, disposal and cleanup of hazardous and non-hazardous wastes. With federal approval, the individual states administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent requirements. Although certain petroleum production wastes are exempt from regulation as hazardous wastes under RCRA, such wastes may constitute “solid wastes” that are subject to the less stringent requirements of non-hazardous waste provisions.
Administrative, civil and criminal penalties can be imposed for failure to comply with waste handling requirements. Moreover, the U.S. Environmental Protection Agency ("EPA") or state or local governments may adopt more stringent requirements for the handling of non-hazardous wastes or recategorize some non-hazardous wastes as hazardous for future regulation. Indeed, legislation has been proposed from time to time in Congress to recategorize certain oil and natural gas exploration, development and production wastes as hazardous wastes. Several environmental organizations have also petitioned the EPA to modify existing regulations to recategorize certain oil and natural gas exploration, development and production wastes as hazardous. Any such changes in these laws and regulations could have a material adverse effect on our capital expenditures and operating expenses. Although we do not believe the current costs of managing our wastes, as presently classified, to be significant, any legislative or regulatory reclassification of oil and natural gas exploration and productionE&P wastes could increase our costs to manage and dispose of such wastes.
Remediation of Hazardous Substances. The Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA" or "Superfund") and analogous state laws generally impose liability without regard to fault or legality of the original conduct, on classes of persons who are considered to be responsible for the release of a hazardous substance into the environment. These persons include the current owner or operator of a contaminated facility, a former owner or operator of the facility at the time of contamination and those persons that disposed or arranged for the disposal of the hazardous substance at the facility. Liability for the costs of removing or remediating previously disposed wastes or contamination, damages to natural resources, the costs of conducting certain health studies, amongst other things, is strict and joint and several. In the course of
6



our operations, we use materials that, if released, would be subject to CERCLA and comparable state laws. Therefore, governmental agencies or third parties may seek to hold us responsible under CERCLA and comparable state statutes for all or part of the costs to clean up sites at which such hazardous substances have been released.
NORM. In the course of our operations, some of our equipment may be exposed to naturally occurring radioactive materials ("NORM") associated with oil and gas deposits and, accordingly, may result in the generation of wastes and other materials containing NORM. NORM exhibiting levels of radiation in excess of established state standards are subject to special handling and disposal requirements, and any storage vessels, piping and work area affected by NORM may be subject to remediation or restoration requirements.
Water Discharges. The Clean Water Act, Safe Drinking Water Act, Oil Pollution Act and analogous state laws and regulations impose restrictions and strict controls regarding the unauthorized discharge of pollutants, including produced waters and other gas and oil wastes, into regulated waters. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or the state. Also, spill prevention, control and countermeasure plan requirements require appropriate containment berms and similar structures to help prevent the contamination of regulated waters.
Air Emissions. The Clean Air Act ("CAA") and comparable state laws and regulations, regulate emissions of various air pollutants through the issuance of permits and the imposition of other emissions control requirements. The EPA has developed, and continues to develop, stringent regulations governing emissions of air pollutants from specified sources. New facilities may be required to obtain permits before work can begin, and existing facilities may be required to obtain additional permits and incur capital costs in order to remain in compliance. These and other laws and regulations may increase the costs of compliance for some facilities where we operate. Obtaining or renewing permits also has the potential to delay the development of oil and natural gas projects.
Climate Change. In the United States, no comprehensive climate change legislation has been implemented at the federal level. However,level, though recently passed laws such as the IRA 2022 advance numerous climate-related objectives. Additionally, following the U.S. Supreme Court finding that GHG emissions constitute a pollutant under the CAA, the EPA has adopted regulations that, among other things, establish construction and operating permit reviews for GHG 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, implement New Source Performance Standards directing the reduction of certain pollutants from certain new, modified, or reconstructed facilities in the oil and natural gas sector, and together with the Department of Transportation ("DOT"), implementing GHG emissions limits on
6


vehicles manufactured for operation in the United States. In September 2020, the Trump Administration revised prior regulations to rescind certain methane standards and remove the transmission and storage segments from the source category for certain regulations. However, subsequently, the U.S. Congress approved, and President Biden signed into law, a resolution under the Congressional Review Act to repeal the September 2020 revisions to the methane standards, effectively reinstating the prior standards. Additionally, in November 2021, the EPA issued a proposed rule that, ifhas recently finalized would establish OOOO(b) new source and OOOO(c) first-time existing source ofrules covering the standards of performance for methane and volatile organic compoundcompounds emissions for oil and gas facilities. Operators of affected facilities, will have to comply with specific standards of performance to includeincluding leak detection, using optical gas imagingmonitoring and subsequent repair, equipment, and reduction ofa "super-emitter" response program to timely mitigate emissions events as detected by 95% through capturegovernmental agencies or qualified third parties, triggering certain investigation and control systems. The EPA plansrepair requirements. These requirements were finalized in 2023, but may be subject to issue a supplemental proposal in 2022 containing additional requirements not included in the November 2021 proposed rule and anticipates the issuance of a final rule by the end of the year.legal challenge.
Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on such areas such as GHG cap and trade programs, carbon taxes, reporting and tracking programs, and restriction of emissions. At the international level, the United Nations-sponsored "Paris Agreement," requires member states to submit non-binding, individually-determined reduction goals known as Nationally Determined Contributions (“NDCs”("NDCs") every five years after 2020. Following President Biden’sthe president’s executive order in January 2021, the United States rejoined the Paris Agreement and, in April 2021, established a goal of reducing economy-wide net GHG emissions 50-52% below 2005 levels by 2030. Additionally, at the 26th Conference of the Parties (“COP26”) in Glasgow in November 2021,Some countries, including the United States, and the European Union jointly announced the launch ofhave additionally made commitments to reduce global methane emissions through initiatives such as the Global Methane Pledge; an initiative committingPledge, and have been called upon to a collective goal of reducing global methane emissions by at least 30 percent from 2020 levels by 2030, including “all feasible reductions” in the energy sector.phase out inefficient fossil fuel subsidies. However, the impacts of these actions are unclear at this time. For more information, see our risk factors titled "Our and our customers’ operations are subject to a series of risks arising out of the threat of climate change that could result in increased operating costs, limit the areas in which oil and natural gas production may occur, and reduce demand for the products and services we provide" and "The IRA 2022 could accelerate the transition to a low carbon economy and could impose new costs on our customers’ operations."
Governmental, scientific, and public concern over the threat of climate change arising from GHG emissions has resulted in increasing political risks in the United States, including climate-change-related pledges made by certain candidates for public office. On January 27, 2021, President Bidenthe president issued an executive order that commits to substantial action on climate change, calling for, among other things, the increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry and an increased emphasis on climate-related risk across government agencies and economic sectors. The executive order also suspendssuspended the issuance of new leases for oil and gas development on federal land;land for a time; for more information, see our regulatory disclosure titled "Regulation"Regulation of Hydraulic Fracturing and Related

Activities." Other actions that the Biden Administrationcurrent government may take include the imposition of more restrictive requirements for the development of pipeline infrastructure or liquefied natural gas export facilities or more restrictive GHG emissions limitations for oil and gas facilities. For example, in January 2024 the government announced a temporary pause on pending decisions on liquefied natural gas exports to certain countries. Litigation risks are also increasing as a number of parties have sought to bring suit against certain oil and natural gas companies operating in the United States in state or federal court, alleging among other things, that such companies created public nuisances by producing fuels that contributed to climate change or that such companies have been aware of the adverse effects of climate change but failed to adequately disclose those impacts to their investors or customers.
The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other regulatory initiatives that impose more stringent standards for GHG emissions from the oil and natural gas sector or otherwise restrict the areas in which this sector may produce oil and natural gas or generate GHG emissions could result in increased costs of compliance or costs of consuming, and thereby reduce demand for, oil and natural gas, which could reduce demand for our services and products.
Moreover, climate change may result in various physical risks, such as the increased frequency or intensity of extreme weather events or changes in the meteorological and hydrological patterns, that could adversely impact us, our customers’ and our suppliers’ operations. Such physical risks may result in damage to our customers’ facilities or otherwise adversely impact our operations, such as if facilities are subject to water use curtailments in response to drought, or demand for our customers’ products, such as to the extent warmer winters reduce the demand for energy for heating purposes, which may ultimately reduce demand for the products and services we provide. Such physical risks may also impact our suppliers, which may adversely affect outour ability to provide our products and services. Extreme weather conditions can interfere with our operations and increase our costs, and damage resulting from extreme weather may not be fully insured.
Endangered and Threatened Species. Environmental laws such as the Endangered Species Act ("ESA"("ESA") and analogous state laws may impact exploration, development and production activities in areas where we operate. The ESA provides broad protection for species of fish, wildlife and plants that are listed as threatened or endangered. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act and various state analogs. The U.S. Fish and Wildlife Service ("FWS"("FWS") may identify previously unidentified endangered or threatened species or may designate
7


critical habitat and suitable habitat areas that it believes are necessary for survival of a threatened or endangered species. For example, the dunes sagebrush lizard, which is found only in the active and semi-stable shinnery oak dunes of southeastern New Mexico and adjacent portions of Texas (including areas where our customers operate), was a candidate species for listing under the ESA by the FWS for many years. As a result of a recent settlement with certain environmental groups, the FWS, in July 2020, acted on a petition to listMost recently, the dunes sagebrush lizard finding sufficient information to warrant a formal one-year review to consider listing the species. While that deadline has been missed, theproposed for listing review is reportedly ongoing; additionally,as endangered in July 2023, FWS has also solicited comments on a proposedentered into voluntary conservation agreementagreements that would implement certain protective practices for the species and authorize incidental take of the species resulting from certain covered activities, including exploration and development of oil and gas fields. However, to the extent any protections are implemented for this or any other species, it could cause us or our customers to incur additional costs or become subject to operating restrictions or operating bans in the affected areas.
Regulation of Hydraulic Fracturing and Related Activities. Our hydraulic fracturing operations are a significant component of our business. Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons, particularly natural gas, from tight formations, including shales. The process, which involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate production, is typically regulated by state oil and natural gas commissions. However, federal agencies have asserted regulatory authority over certain aspects of the process. For example, the EPA has previously issued a series of rules under the CAA that establish new emission control requirements for certain oil and natural gas production and natural gas processing operations and associated equipment. Separately, the Bureau of Land Management ("BLM") previously finalized a rule governing hydraulic fracturing on federal lands, but that rule was subsequently rescinded. Although several of these rulemakings have been rescinded, modified or subjected to legal challenges, new or more stringent regulations may be promulgated by the Biden administration.current government. For example, in January 2021, President Biden issuedthe Bureau of Land Management (“BLM”) recently proposed a rule that would limit flaring from well sites on federal lands, as well as allow the delay or denial of permits if BLM finds that an executive order suspending newoperator’s methane waste minimization plan is insufficient. The current government has also called for revisions and restrictions to the leasing activities, but not operations under existing leases,and permitting programs for oil and gas exploration and productiondevelopment on non-Indian federal lands pending completion ofand, for a comprehensive review and reconsideration oftime, suspended federal oil and gas permitting and leasing practices that take into consideration potential climate and other impacts associated with oil and gas activities on such lands and waters. Although the federal court for the Western District of Louisiana issued a preliminary injunction against the leasing pause, in response to the executive order, theactivities. The Department of the Interior ("DOI"("DOI") has also issued a report recommending various changes to the federal leasing program, though many such changes would require Congressionalcongressional action. In July 2023, the BLM proposed a rule to update the fiscal terms of federal oil and gas leases, which would increase fees, rents, royalties, and bonding requirements. The rule would also add new criteria for BLM to consider when determining whether to lease nominated land, including the presence of important habitats or wetlands, the presence of historical properties or sacred sites, and recreational use of the land. BLM anticipates a final action on the proposal in Spring 2024. As a result, we cannot predict the final scope of regulations or restrictions that may apply to oil and gas operations on federal lands. However, any regulations that restrict, ban or effectively ban such operations may adversely impact demand for our products and services. Further, legislation to amend the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing (except when diesel fuels are used) from
8



the definition of “underground injection” and require federal permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to require disclosure of the chemical constituents of the fluids used in the fracturing process, have previously been proposed in Congress. Several states and local jurisdictions in which we or our customers operate also have adopted or are considering adopting regulations that could restrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating standards and/or require the disclosure of the composition of hydraulic fracturing fluids.

Federal and state governments have also investigated whether the disposal of produced water into underground injection wells has caused increased seismic activity in certain areas. In response to concerns regarding induced seismicity, regulators in some states have imposed, or are considering imposing, additional requirements in the permitting of produced water disposal wells or otherwise to assess any relationship between seismicity and the use of such wells. For example, Oklahoma has issued rules for wastewater disposal wells that impose permitting and operating restrictions and reporting requirements on disposal wells in proximity to faults and also, from time to time, has implemented plans directing certain wells where seismic incidents have occurred to restrict or suspend disposal well operations. In particular, the Oklahoma Corporation Commission’s well completion seismicity guidelines for operators in the SCOOP and STACK require hydraulic fracturing operations to be suspended following earthquakes of certain magnitudes in the vicinity. In addition, the Oklahoma Corporation Commission’s Oil and Gas Conservation Division has previously issued an order limiting future increases in the volume of oil and natural gas wastewater injected into the ground in an effort to reduce the number of earthquakes in the state. The Texas Railroad Commission ("("TRRC") has adopted similar rules and, in September 2021, issued a notice to disposal well operators in the Gardendale Seismic Response Area near Midland, Texas to reduce daily injection volumes following multiple earthquakes above a 3.5 magnitude over an 18 month period. The notice also required disposal well operators to provide injection data to TRRC staff to further analyze seismicity in the area. Subsequently, the TRRC orderedincluding the indefinite suspension of all deep oil and gas produced water injection wells in certain areas covered by the area, effective December 31, 2021. While we cannot predict the ultimate outcome of these actions, any action that temporarily or permanently restricts the availability of disposal capacity for produced water or other oilfield fluids may increase our customers’ costs or require them to suspend operations, which may adversely impact demand for our products and services.TRRC’s seismic response program.

Increased regulation of hydraulic fracturing and related activities could subject us and our customers to additional permitting and financial assurance requirements, more stringent construction specifications, increased monitoring, reporting and record keeping obligations, and plugging and abandonment requirements. New requirements could result in increased operational costs for us and our customers, and reduce the demand for our services. For more information on each of these items, see our risk factor titled "Federal and state legislative and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional operating restrictions or delays."
OSHA Matters. The Occupational Safety and Health Act ("OSHA") and comparable state statutes 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.
Human Capital

talent acquisition efforts.
Compensation, Health, Wellness and Benefits. Our employee benefit offerings are designed to meet the varied and evolving needs of a diverse workforce across the Company and we believe are consistent with those provided by our peer companies with which we compete for talent. The Company provides employees with the ability to participate in health and welfare plans, including medical, dental, life, accidental death and dismemberment and short-term and long-term disability insurance plans. Since the beginning of COVID-19, we have implemented processes and procedures to help address COVID-19 matters. Below are some of the adjustments we made to address the COVID-19 pandemic;
instituted periodic update, guidelines and questionnaires to all employees to address and identify COVID-19 related matters;
initially instituted a temporary remote work environment in response to COVID-19 and have retained the flexibility for employees to work remotely when necessary or advisable;
encouraged all employees to adhere to guidelines provided by the Centers for Disease Control and Prevention; and
provided coverage for COVID-19 testing and vaccination under the Company’s medical plan at no cost to our employees.
In 2021, we performed an extensive review2023, as part of our health-related benefits program to ensure that our offerings are market competitive and effectively utilized by employees. Based on that review, we made comprehensive adjustments to our health-related benefits programs, which improved the cost and quality of coverage. We significantly increased the number of employee meetings to provide education and encourage individuals to maximize the value of benefits offered, resulting in an overall increase in participation and positive feedback from employees.

         We have also recently initiated a plan to review our 401(k) plan, and implement improvements in 2022 with a focus on improving plan structure, reducing program administration, providing employeewe introduced opportunities for holistic financial wellness education and increasinggroup and individual consultations for employees.

Item 1A.    Risk Factors.
The following is a description of significant factors that could cause actual results to differ materially from those contained in forward-looking statements made in this Annual Report and presented elsewhere by management from time to time. Such factors may have a material adverse effect on our business, financial condition and results of operations. It is not possible to predict or identify all such factors. Consequently, you should not consider any such list to be a complete statement of all our potential risks or uncertainties. Due to these, and other factors, past performance should not be considered an indication of future performance.
Risks Inherent in Our Business and Industry
Our business and financial performance depends on the historically cyclical oil and natural gas industry and particularly on the level of capital spending and exploration and productionE&P activity within the United States and in the Permian Basin, and a decline in prices for oil and natural gas may cause fluctuation in operating results or otherwise have an adverse effect on our revenue, cash flows, profitability and growth.
Demand for most of our services depends substantially on the level of capital expenditures in the Permian Basin by companies in the oil and natural gas industry. As a result, our operations are dependent on the levels of capital spending and activity in oil and gas exploration, development and production. Demand for our services is largely dependent on oil and natural gas prices, and our customers’ well completion budgets and rig count. Prolonged low oil and gas prices would generally depress the level of oil and natural gas exploration, development, production, and well completion activity and would result in a corresponding decline in the demand for the hydraulic fracturingcompletion services that we provide. Historically, oil prices and markets have been extremely volatile. Prices are affected by many factors beyond our control. WTI oiThe l price declined significantly in 2015 and 2016 to approximately $30 per barrel, but subsequently recovered in 2017. Furthermore, in March 2020,average WTI oil price declined to a low of approximately $20 per barrel was approximately $78, $94 and then subsequently recovered. The average WTI oil prices per barrel were approximately $68 $39 and $57 for the years ended December 31, 2023, 2022 and 2021, 2020 and 2019, respectively. Recently, WTI oil price reached a 7-year high of over $90 per barrel in February 2022. In 2023, the last three years, the highly volatilevolatility and unpredictable nature ofoverall decline in oil and natural gas prices caused a reduction in our customers’ spending and associated drilling and completion activities, which has had and may continue to have an adverse effect on our revenue and cash flows, if the WTI oil prices remainprice remains highly volatile or declinedeclines in the future.
Many factors over which we have no control affect the supply of, and demand for our services, and our customers’ willingness to explore, develop and produce oil and natural gas, and therefore, influence prices for our services, including:
the severity and duration of world health events, including the COVID-19 pandemic, related economic repercussions;
the actions by the members of OPEC+ with respect to oil production levels and announcements of potential changes in such levels, including the ability of the OPEC+ countries to agree on and comply with supply limitations;
the domestic and foreign supply of, and demand for, oil and natural gas;
the level of prices, and expectations about future prices, of oil and natural gas;
the level of global oil and natural gas exploration and production;E&P;
the cost of exploring for, developing, producing and delivering oil and natural gas;
the supply of and demand for drilling and hydraulic fracturing and wireline equipment, including the supply and demand for lower emissions hydraulic fracturing and wireline equipment;
cost increases and supply chain constraints related to our services;
the expected decline in rates of current production;
the price and quantity of foreign imports;
political and economic conditions in oil and natural gas producing countries and regions, including the United States, the Middle East, Africa, South America and Russia;
11


the actions taken by the United States and other countries on climate change or to transition away from fossil fuels;
operational challenges relating to the COVID-19 pandemicseverity and efforts to mitigate the spreadduration of the virus, including logistical challenges, protecting theworld health events and well-being of our employees, remote work arrangements, performance of contracts and supply chain disruptions;related economic repercussions;
speculative trading in crude oil and natural gas derivative contracts;
the level of consumer product demand;
11



the discovery rates of new oil and natural gas reserves;
contractions in the credit market;
the strength or weakness of the U.S. dollar;
available pipeline and other transportation capacity;
the levels of oil and natural gas storage;
weather conditions and other natural disasters;
domestic and foreign tax policy;
domestic and foreign governmental approvals and regulatory requirements and conditions, including tighter emissions standards in the energy industry;
the continued threat of terrorism and the impact of military and other action, including military action in the Middle East;
political or civil unrest in the United States or elsewhere;elsewhere, including the Russia-Ukraine war and the conflict in the Israel-Gaza region and related instability in the Middle East, including from Houthi rebels in Yemen;
technical advances affecting energy consumption;
the proximity and capacity of oil and natural gas pipelines and other transportation facilities;
the price and availability of alternative fuels;
the ability of oil and natural gas producers to raise equity capital and debt financing;
merger and divestiture activity among oil and natural gas producers; and
overall domestic and global economic conditions.
These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas price movements with any certainty. For example,In 2022, Russia launched a large-scale invasion of Ukraine, leading to armed hostilities and imposition of sanctions on Russian economic trades. Since October 2023, an ongoing conflict between Israel and Palestinian militants in 2020, Saudi Arabia and Russia failedthe Israel-Gaza region has led to agree on a plan to cut production of oil and gas within OPEC and Russia. Subsequently, Saudi Arabia announced plans to increase production and reduce the prices at which they sell oil.armed hostilities. These events, combined with the COVID-19 pandemic that has negativelywhich have impacted the economic activity and disrupted theglobal supply chains of certain of our customers,chain dynamics, have contributed to the unpredictable nature of crude oil prices.
12


The cyclical nature of the oil and natural gas industry may cause our operating results to fluctuate.
We derive our revenues from companies in the oil and natural gas exploration and productionE&P industry, a historically cyclical industry with levels of activity that are significantly affected by the levels and volatility of oil and natural gas prices. We have experienced, and may in the future experience, significant fluctuations in operating results as a result of the reactions of our customers to changes in oil and natural gas prices. For example, thea decline in and unpredictable nature of oil and gas prices, in 2019 and 2020, combined with adverse changes in the capital and credit markets, and the COVID-19 pandemic in 2020, causedcould cause many exploration and productionE&P companies to significantly reduce their 2020 and 2021 capital budgets and drilling activity. This resultedcould result in a significant decline in demand for oilfield services and could adversely impactedimpact the prices oilfield servicesservice companies can charge for their services. These factors have materially and adversely affected our business, results of operations and financial condition. In addition, a majority of the service revenue we earn is based upon a charge for a relatively short period of time (for example, a day, a week or a month) for the actual period of time the service is provided to our customers. By contracting services on a short‑term basis, we are exposed to the risks of a rapid reduction in market prices and utilization and resulting volatility in our revenues.
Events outside of our control, including an epidemic or outbreak of an infectious disease, such as COVID-19, may materially adversely affect our business.
          We face risks related to epidemics, outbreaks or other public health events that are outside of our control, and could significantly disrupt our operations and adversely affect our financial condition. The global or national outbreak of an illness or any other communicable disease, or any other public health crisis, such as COVID-19, may cause disruptions to our business and operational plans, which may include (i) shortages of employees, (ii) unavailability of contractors and subcontractors, (iii) interruption of supplies from third parties upon which we rely, (iv) recommendations of, or restrictions imposed by, government and health authorities, including quarantines, and (v) restrictions that we and our contractors, subcontractors and our customers impose, including facility shutdowns, to ensure the safety of employees. For example, in response to COVID-19, we made adjustments to some of our business processes that helped and will continue to help address the impact to the COVID-19 pandemic.
          The COVID-19 pandemic has spread across the globe and impacted financial markets and worldwide economic activity and adversely affected our operations in the recent years. In addition, the effects of COVID-19 across the globe have negatively impacted the domestic and international demand for crude oil and natural gas, which has contributed to price volatility, impacted the operations and activity levels of our customers and materially and adversely affected the demand for oilfield services. These factors also negatively impacted our current suppliers and their ability or willingness to provide the necessary equipment, parts or raw materials, and they may fail to deliver the products timely and in the quantities required. Any resulting delays or restrictions from COVID-19 on the provision of our services could have a material adverse effect on our business, financial condition, results of operations and cash flows. As the potential impact from COVID-19 is difficult to predict, the extent to which it may negatively affect our operating results or the duration of any potential business disruption is uncertain. Any potential impact will depend on future developments and new information that may emerge regarding the COVID-19 infection rate or the efficacy and distribution of COVID-19 vaccines, and the actions taken by authorities to contain it or treat its impact, all of which are beyond our control. These potential impacts, while uncertain, could adversely affect our business, results of operations and financial condition.
The majority of our operations are located in the Permian Basin, making us vulnerable to risks associated with operating in one major geographic area.
Our operations are geographically concentrated in the Permian Basin. For the years ended December 31, 2021, 20202023, 2022 and 2019,2021, approximately 98.7%98.1%, 99.5%98.3% and 99.4%98.7%, respectively, of our revenues were attributable to our operations in the Permian Basin. As a result of this concentration, we may be disproportionately exposed to the impact of regional supply and demand factors,
12



delays or interruptions of production from wells in the Permian Basin caused by significant governmental regulation, processing or transportation capacity constraints, market limitations, curtailment of production or interruption of the processing or transportation of oil and natural gas produced from the wells in these areas. In addition, the effect of fluctuations on supply and demand may become more pronounced within specific geographic oil and natural gas producing areas such as the Permian Basin, which may cause these conditions to occur with greater frequency or magnify the effects of these conditions. Due to the concentrated nature of our operations, we could experience any of the same conditions at the same time, resulting in a relatively greater impact on our revenue than they might have on other companies that have more geographically diverse operations.
The IRA 2022 could accelerate the transition to a low carbon economy and could impose new costs on our customers’ operations.
13


In August 2022, the president signed the IRA 2022 into law. The IRA 2022 provides for hundreds of billions of dollars in incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles and supporting infrastructure and carbon capture and sequestration, amongst other provisions. These incentives could further accelerate the transition of the economy away from the use of fossil fuels towards lower- or zero-carbon emissions alternatives, which could decrease demand for oil and gas and consequently adversely affect the business of our customers, thereby reducing demand for our services. In addition, the IRA 2022 imposes the first ever federal fee on the emission of GHG through a methane emissions charge. The IRA 2022 amends the federal CAA to impose a fee on the emission of methane from sources required to report their GHG emissions to the EPA, including those sources in the offshore and onshore petroleum and natural gas production and gathering and boosting source categories. The methane emissions charge will start in calendar year 2024 at $900 per ton of methane, increase to $1,200 in 2025, and be set at $1,500 for 2026 and each year after. Calculation of the fee is based on certain thresholds established in the IRA 2022. The methane emissions charge could increase our customers’ operating costs and adversely affect their businesses, thereby reducing demand for our services.
Our business may be adversely affected by a deterioration in general economic conditions or a weakening of the broader energy industry.
A prolonged economic slowdown or recession in the United States, adverse events relating to the energy industry or regional, national and global economic conditions and factors, particularly a further slowdown in the exploration and productionE&P industry, could negatively impact our operations and therefore adversely affect our results. The risks associated with our business are more acute during periods of economic slowdown or recession because such periods may be accompanied by decreased exploration and development spending by our customers, decreased demand for oil and natural gas and decreased prices for oil and natural gas. In 2020, the COVID-19 pandemic and the turmoil between the members of OPEC+ caused oil prices to fall substantially and adversely impacted the global economy; a recurrence of similar events would heighten the risk of a prolonged economic slowdown or recession in the United States.
New technology may cause us to become less competitive.
The oilfield servicesservice industry is subject to the introduction of new drilling and completion techniques and services using new technologies, some of which may be subject to patent or other intellectual property protections. As competitors and others use or develop new or comparable technologies in the future, we may lose market share or be placed at a competitive disadvantage. The transition to lower emissions equipment is capital intensive and could require us to convert all our conventional Tier II equipment to lower emissions equipment. If we are unable to quickly transition to lower emissions equipment, the demand for our services could be adversely impacted. For example, many E&P companies, including our customers, are transitioning to a lower emissions operating environment and may require us to invest in pressure pumping equipment with lower emissions profile.profiles. Further, we may face competitive pressure to develop, implement or acquire and deploy certain technology improvements at a substantial cost, such as our FORCEDuraStim®SM electric-powered hydraulic fracturing fleets deployed in 2023, or the cost of implementing or purchasing a technology like FORCEDuraStim®SM may be substantially higher than anticipated, and we may not be able to successfully implement the DuraStim® fleets or other technologies we may purchase. In 2022, we recorded an impairment of $57.5 million on our DuraStim® electric-powered equipment because they did not meet our expectations.Some of our competitors have greater financial, technical and personnel resources that may allow them to enjoy technological advantages and develop and implement new products on a timely basis or at an acceptable cost. We cannot be certain that we will be able to develop and implement new technologies or products on a timely basis or at an acceptable cost. Limits on our ability to develop, effectively use and implement new and emerging technologies could have a material adverse effect on our business, financial condition, prospects or results of operations.
Our operations require substantial capital and we may be unable to obtain needed capital or financing on satisfactory terms, or at all, which could limit our ability to grow.
The oilfield servicesservice industry is capital intensive. In conducting our business and operations, we have made, and expect to continue to make, substantial capital expenditures. Our total capital expenditures incurred were approximately $165.2310.0 million, $81.2$365.3 million and $400.7$165.2 million during the years ended December 31, 2021, 20202023, 2022 and 2019.2021. We have historically financed capital expenditures primarily with funding from cash on hand, cash flow from operations, equipment and vendor financing and
13



borrowings under our credit facility. We may be unable to generate sufficient cash from operations and other capital resources to maintain planned or future levels of capital expenditures which, among other things, may prevent us from acquiring new equipment (including equipment with a lower emissions profile) or properly maintaining our existing equipment. Any disruptions or volatility in the global financial markets may lead to an increase in interest rates or a contraction in credit availability impacting our ability to finance our operations. Our borrowing base changed from $61.1was $152.0 million as of December 31, 2021 to approximate2023ly $79.0 million as of February 18, 2022 due to a change in our eligible accounts receivable.. If our customer activity levels decline in the future resulting in a decrease in our eligible accounts receivable, our borrowing base could decline. This could put us at a competitive disadvantage or interfere with our growth plans. Further, our actual capital expenditures could exceed our capital expenditure budget. In the event our capital expenditure requirements at any time are greater than the amount of liquidity we have available, we could be required to seek additional sources of capital, which may include debt financing, joint venture partnerships, sales of assets, offerings of debt or equity securities or other means. We may not be able to obtain any such alternative source of capital. We may be required to curtail or eliminate contemplated activities. If we can obtain alternative sources of capital, the terms of such alternative may not be favorable to us. In particular, the terms of any debt financing may include covenants that significantly restrict our operations. Our inability to grow as planned may reduce our chances of maintaining and improving profitability.
Concerns over general economic, business or industry conditions may have a material adverse effect on our results of operations, liquidity and financial condition.
Concerns over global economic conditions, geopolitical issues (including the Russia-Ukraine war and conflicts in the Israel-Gaza region), public health crises, (including the COVID-19 pandemic), interest rates, inflation, the availability and cost of credit in the United States and foreign financial markets have contributed to increased economic uncertainty and diminished expectations for the global economy. These factors, combined with volatility in commodity prices, business and consumer confidence and unemployment rates, could
14


precipitate an economic slowdown. Concerns about global economic growth have had a significant adverse impact on global financial markets and commodity prices. The historically unpredictable nature of oil and natural gas prices, and particularly the volatility over the past two years have caused a reduction in our customers’ spending and associated drilling and completion activities, which had and may continue to have an adverse effect on our revenue and cash flows. If the economic climate in the United States or abroad deteriorates or remains uncertain, worldwide demand for petroleum products could diminish, which could impact the price at which oil, natural gas and natural gas liquids can be sold, which could affect the ability of our customers to continue operations and adversely impact our results of operations, liquidity and financial condition.
Our indebtedness and liquidity needs could restrict our operations and make us more vulnerable to adverse economic conditions.adversely affect our financial condition.
Our business is capital intensive and our existing and future indebtedness, whether incurred in connection with acquisitions, operations or otherwise, may adversely affect our operations and limit our growth, and we may have difficulty making debt service payments on such indebtedness as payments become due. Our level of indebtedness may affect our operations in several ways, including the following:
•    increasing our vulnerability to general adverse economic and industry conditions;
•    the covenants that are contained in the agreements governing our indebtedness could limit our ability to borrow funds, dispose of assets, pay dividends and make certain investments;
•    our debt covenants could also affect our flexibility in planning for, and reacting to, changes in the economy and in our industry;
•    any failure to comply with the financial or other debt covenants, including covenants that impose requirements to maintain certain financial ratios, could result in an event of default, which could result in some or all of our indebtedness becoming immediately due and payable;
•    our level of debt could impair our ability to obtain additional financing, or obtain additional financing on favorable terms in the future for working capital, capital expenditures, research and development efforts, potential strategic acquisitions or other general corporate purposes;
placing us at a competitive disadvantage relative to competitors that have less debt; and
•    our business may not generate sufficient cash flow from operations to enable us to meet our obligations under our indebtedness.
14



Furthermore, interest rates on future indebtedness could be higher than current levels, causing our financing costs to increase accordingly. Changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our shares, and a rising interest rate environment could have an adverse impact on the price of our shares, our ability to issue equity or incur debt.
Restrictions in our ABL Credit Facility and any future financing agreements may limit our ability to finance future operations or capital needs or capitalize on potential acquisitions and other business opportunities.
The operating and financial restrictions and covenants in our credit facility and any future financing agreements could restrict our ability to finance future operations or capital needs or to expand or pursue our business activities. For example, our ABL Credit Facility restricts or limits our ability to:
grant liens;
incur additional indebtedness;
engage in a merger, consolidation or dissolution;
enter into transactions with affiliates;
sell or otherwise dispose of assets, businesses and operations;
materially alter the character of our business as currently conducted; and
make acquisitions, investments and capital expenditures.
Furthermore, our ABL Credit Facility contains certain other operating and financial covenants. Our ability to comply with the covenants and restrictions contained in the ABL Credit Facility may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired. If we violate any of the restrictions, covenants, ratios or tests in our ABL Credit Facility, a significant portion of our indebtedness may become immediately due and
15


payable and our lenders’ commitment to make further loans to us may terminate. Further, our borrowing base, as redetermined monthly, is tiedhas a borrowing base of the sum of 85.0% to 85.0%90.0% of eligible accounts receivable.receivable and 80% of eligible unbilled accounts (up to a maximum of 25% of the borrowing base), in each case, depending on the credit ratings of our accounts receivable counterparties, less customary reserves (the “Borrowing Base”). Changes to our operational activity levels or customer concentration levels have an impact on our total eligible accounts receivable, which could result in significant changes to our borrowing base and therefore our availability under our ABL Credit Facility. For example, our borrowing base changed from $61.1 million as of December 31, 2021 to approximately $79.0 million as of February 18, 2022 due to a change in our eligible accounts receivable. If our customer activity declines in the future, our borrowing base could decline. If our borrowing base is reduced below the amount of our outstanding borrowings, we will be required to repay the excess borrowings immediately on demand by the lenders. We might not have, or be able to obtain, sufficient funds to make these accelerated payments. Any subsequent replacement of our ABL Credit Facility or any new indebtedness could have similar or greater restrictions. Please read "Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Credit Facility and Other Financing Arrangements."
We may incur debt and our indebtedness could adversely affect our operations and financial condition.
          Our business is capital intensive and we may seek to raise debt capital to fund our business and growth strategy. Indebtedness could have negative consequences that could materially and adversely affect our business, financial condition, results of operations, cash flows and prospects, such as:

requiring us to dedicate a substantial portion of our cash flow from operating activities to payments on our indebtedness, thereby reducing the availability of cash flow to fund working capital, capital expenditures, research and development efforts, potential strategic acquisitions and other general corporate purposes;
limiting our ability to obtain additional financing to fund growth, working capital or capital expenditures, or to fulfill debt service requirements or other cash requirements;
increasing our vulnerability to economic downturns and changing market conditions; and
placing us at a competitive disadvantage relative to competitors that have less debt.
          Furthermore, interest rates on future indebtedness could be higher than current levels, causing our financing costs to increase accordingly. In addition, LIBOR and other “benchmark” rates are subject to ongoing national and international regulatory scrutiny and reform. In July 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR by the end of June 2023 for US dollars setting. At this time, no consensus exists as to what rate or rates may become acceptable alternatives to LIBOR and we are unable to predict the effect of any such alternatives on our business and results of operations. However, if LIBOR is phased out without a replacement benchmark, our only option under the ABL Credit Facility will be to borrow at the Base Rate (as defined in the ABL Credit Facility) until an alternative benchmark rate is selected. Changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our shares, and a rising interest rate environment could have an adverse impact on the price of our shares, our ability to issue equity or incur debt.
We may record losses or impairment charges related to goodwill and long-lived assets including intangible assets.
Changes in future market conditions and prolonged periods of low utilization, changes in technology or the sale of assets below their carrying value may cause us to experience losses in our results of operations. These events could result in the recognition of impairment charges or losses from asset sales that negatively impact our financial results. Significant impairment charges or losses from asset sales as a result of a decline in market conditions or otherwise could have a material adverse effect on our results of operations in future periods. For example, in 2021, we recorded loss on disposal of asset $3.5 million in connection with the sale of our two turbines. In addition,2022, we recorded impairment charges of $57.5 million in connection with our DuraStim® equipment remains under evaluation and has yet to be commercialized. If we are not able to successfully commercialize the electric powered hydraulic fracturing equipmentDuraStim®. equipment, and are not able to deploy the equipment for alternative uses, we will incur impairment losses on the carrying value of the DuraStim® equipment. As of December 31, 2021, the carrying value of our DuraStim® equipment is approximately $90 million. If oil and natural gas prices trade at depressed price levels, as experienced in the first half of 2020, and our equipment remains idle or under-utilized, the estimated fair value of such equipment may decline, which will result in additional impairment expense in the future.

Our operations are subject to unforeseen interruptions and hazards inherent in the oil and natural gas industry, for which we may not be adequately insured and which could cause us to lose customers and substantial revenue.
Our operations are exposed to the risks inherent to our industry, such as equipment defects, vehicle accidents, worksite injuries to our or third-party personnel, fires, explosions, blowouts, surface cratering, uncontrollable flows of gas or well fluids, pipe or pipeline failures, abnormally pressured formations and various environmental hazards, such as oil spills and releases of, and
1615



spills and releases of, and exposure to, hazardous substances. For example, our operations are subject to risks associated with hydraulic fracturing, including any mishandling, surface spillage or potential underground migration of fracturing fluids, including hydrochloric acid and other chemical additives. In addition, our operations are exposed to potential natural disasters, including blizzards, tornadoes, storms, floods, other adverse weather conditions and earthquakes. The occurrence of any of these events could result in substantial losses to us due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, pollution or other environmental damage, clean‑upcleanup responsibilities, regulatory investigations and penalties or other damage resulting in curtailment or suspension of our operations or the loss of customers. The cost of managing such risks may be significant. The frequency and severity of such incidents will affect operating costs, insurability and relationships with customers, employees and regulators. In particular, our customers may elect not to purchase our services if they view our environmental or safety record as unacceptable, which could cause us to lose customers and substantial revenues.
Our insurance may not be adequate to cover all losses or liabilities we may suffer. We are also self-insured up to $10 million per occurrence for certain losses arising from or attributable to fire and/or explosion at the wellsites.wellsites that do not have qualified fire suppression measures. Furthermore, we may be unable to maintain or obtain insurance of the type and amount we desire at reasonable rates. As a result of market conditions, premiums and deductibles for certain of our insurance policies have increased and could escalate further. In addition, sub‑limits have been imposed for certain risks. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we are not fully insured, it could have a material adverse effect on our business, results of operations and financial condition. In addition, we may not be able to secure additional insurance or bonding that might be required by new governmental regulations. This may cause us to restrict our operations, which might severely impact our financial position.
Since hydraulic fracturing activities are part of our operations, they are covered by our insurance against claims made for bodily injury, property damage and clean‑upcleanup costs stemming from a sudden and accidental pollution event. However, we may not have coverage if we are unaware of the pollution event and unable to report the "occurrence”occurrence" to our insurance company within the time frame required under our insurance policy. In addition, these policies do not provide coverage for all liabilities, and the insurance coverage may not be adequate to cover claims that may arise, or we may not be able to maintain adequate insurance at rates we consider reasonable. A loss not fully covered by insurance could have a material adverse effect on our financial position, results of operations and cash flows.
A terrorist attack, armed conflict or political or civil unrest could harm our business.
Terrorist activities, anti‑terrorist efforts, other armed conflicts and political or civil unrest, including the Russia-Ukraine war and conflicts in the Israel-Gaza region, could adversely affect the U.S. and global economies and could prevent us from meeting financial and other obligations. We could experience loss of business, delays or defaults in payments from payors or disruptions of fuel supplies and markets if pipelines, production facilities, processing plants, refineries or transportation facilities are direct targets or indirect casualties of an act of terror or war. Such activities could reduce the overall demand for oil and natural gas, which, in turn, could also reduce the demand for our services. Terrorist activities, the threat of potential terrorist activities, political or civil unrest and any resulting economic downturn could adversely affect our results of operations, impair our ability to raise capital or otherwise adversely impact our ability to realize certain business strategies.
We may be subject to claims for personal injury and property damage, which could materially adversely affect our financial condition and results of operations.
We operate with most of our customers under master service agreements ("MSAs"). We endeavor to allocate potential liabilities and risks between the parties in the MSAs. Generally, under our MSAs, including those relating to our hydraulic fracturing services, we assume responsibility for, including control and removal of, pollution or contamination which originates above surface and originates from our equipment or services. Our customer assumes responsibility for, including control and removal of, all other pollution or contamination which may occur during operations, including that which may result from seepage or any other uncontrolled flow of drilling fluids. We may have liability in such cases if we are negligent or commit willful acts. Generally, our customers also agree to indemnify us against claims arising from their employees’ personal injury or death to the extent that, in the case of our hydraulic fracturing operations, their employees are injured or their properties are damaged by such operations, unless resulting from our gross negligence or willful misconduct. Similarly, we generally agree to indemnify our customers for liabilities arising from personal injury to or death of any of our employees, unless resulting from gross negligence or willful misconduct of the customer. In addition, our customers generally agree to indemnify us for loss or destruction of customer‑owned property or equipment and in turn, we agree to indemnify our customers for loss or destruction of property or equipment we own. Losses due to catastrophic events, such as blowouts, are generally the responsibility of the customer. However, despite this general allocation of risk, we might not succeed in enforcing such contractual allocation, might incur an unforeseen liability
17


falling outside the scope of such allocation or may be required to enter into an MSA with terms
16



that vary from the above allocations of risk. Litigation arising from a catastrophic occurrence at a location where our equipment and services are being used may result in ourus being named as a defendant in lawsuits asserting large claims. As a result, we may incur substantial losses which could materially and adversely affect our financial condition and results of operation.
We are subject to cyber security risks. A cyber incident could occur and result in information theft, data corruption, operational disruption and/or financial loss.
The oil and natural gas industry has become increasingly dependent on digital technologies to conduct certain processing activities. For example, we depend on digital technologies to perform many of our services and process and record operational and accounting data. At the same time, cyber incidents, including deliberate attacks or unintentional events, have increased.
The frequency and magnitude of cybersecurity attacks is increasing and attackers have become more sophisticated. Cybersecurity attacks are similarly evolving and include without limitation use of 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 other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. We may be unable to anticipate, detect or prevent future attacks, particularly as the methodologies used by attackers change frequently or are not identifiable until deployed. We may also be unable to investigate or remediate incidents as attackers are increasingly using techniques and tools designed to circumvent controls, to avoid detection, and to remove or obfuscate forensic evidence.
The U.S. government has issued public warnings indicating that energy assets might be specific targets of cyber security threats. Our technologies, systems and networks, and those of our vendors, suppliers and other business partners, may become the target of cyberattacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary information, personal information and other data, or other disruption of our business operations. In addition, certain cyber incidents, such as unauthorized surveillance, may remain undetected for an extended period. Our systems and insurance coverage (if any) for protecting against cyber security risks, including cyberattacks, may not be sufficient and may not protect against or cover all of the losses (including potential reputational loss) we may experience as a result of the realization of such risks. As cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate the effects of cyber incidents.
We utilize technologies, controls and procedures, as well as internal staff and external service providers to protect our systems and data, to identify and remediate vulnerabilities and to monitor and respond to threats. However, there can be no assurance that such measures will be sufficient to prevent security breaches from occurring. No security measure is infallible. If we or the third parties with whom we interact were to experience a successful attack, the potential consequences to our business, workforce and the communities in which we operate could be significant, including financial losses, regulatory fines, loss of business, an inability to settle transactions or maintain operations, litigation costs, remediation costs, disruptions related to investigation, and significant damage to our reputation.
We may grow through acquisitions and our failure to properly plan and manage those acquisitions may adversely affect our performance.
We have completed and may in the future pursue, asset acquisitions or acquisitions of businesses. Any acquisition of assets or businesses involves potential risks, including the failure to realize expected profitability, growth or accretion; environmental or regulatory compliance matters or liability; title or permit issues; the incurrence of significant charges, such as impairment of goodwill, or property and equipment or intangible assets or restructuring charges; and the incurrence of unanticipated liabilities and costs for which indemnification is unavailable or inadequate. The process of upgrading acquired assets to our specifications and integrating acquired assets or businesses may also involve unforeseen costs and delays or other operational, technical and financial difficulties and may require a significant amount of time and resources and may divert management’s attention from existing operations or other priorities. For example, in 2023, we acquired the assets and operations of Par Five, and we are in the process of fully integrating all parts of the acquired business into our operations.
We must plan and manage any acquisitions effectively to achieve revenue growth and maintain profitability in our evolving market. Any failure to manage acquisitions effectively or integrate acquired assets or businesses into our existing operations successfully, or to realize the expected benefits from an acquisition or minimize any unforeseen operational difficulties, could have a material adverse effect on our business, financial condition, prospects or results of operations.
We may be adversely affected by the effects of inflation.
17



The Logan LawsuitU.S. inflation rate steadily increased in 2021 and 2022 before decreasing to a moderate level in 2023. Inflation in wages, materials, parts, equipment and other costs has the potential to adversely affect our results of operations, cash flows and financial position by increasing our overall cost structure, particularly if we are unable to achieve commensurate increases in the prices we charge our customers for our products and services. In addition, the existence of inflation in the economy has the potential to result in higher interest rates, which could result in higher borrowing costs, supply shortages, increased costs of labor, weakening exchange rates and other similar effects. Sustained levels of high inflation have likewise caused the U.S. Federal Reserve and other central banks to increase interest rates multiple times in 2023 and the U.S. Federal Reserve may continue to raise benchmark interest rates into 2024 in an effort to curb inflationary pressure on the costs of goods and services across the U.S., which could have the effects of raising the cost of capital and depressing economic growth, either of which—or the combination thereof—could hurt the financial and operating results of our business. To the extent elevated inflation remains, we may experience further cost increases for our operations, including labor costs and equipment. We cannot predict any future trends in the rate of inflation and a material adverse effect onsignificant increase in inflation, to the extent we are unable to timely pass-through the cost increases to our customers, would negatively impact our business, financial condition and results of operation,operations.
Adverse developments affecting the financial services industry, such as events or concerns involving liquidity, defaults or non-performance by financial institutions or transactional counterparties, could adversely affect the Company’s current and cash flows.projected business operations and its financial condition and results of operations.
Events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, concerns or rumors about such events or other similar risks, have in the past and may in the future lead to acute or market-wide liquidity problems. In September 2019,addition, if any of the Company’s customers, suppliers or other business counterparties are unable to access funds held by such a complaint, captioned Richard Logan, Individually and On Behalf of All Others Similarly Situated, Plaintiff, v. ProPetro Holding Corp., et al., (the "Logan Lawsuit"), was filed againstfinancial institution, such parties’ ability to pay their obligations to the Company or to enter into new commercial arrangements requiring additional payments to the Company could be adversely affected.
Inflation and certain of its then current and former officers and directorsrapid increases in interest rates have led to a decline in the trading value of previously issued government securities with interest rates below current market interest rates. Although the U.S. District CourtDepartment of Treasury, Federal Deposit Insurance Corporation ("FDIC") and Federal Reserve Board have announced a program to mitigate the risk of potential losses on the sale of such instruments, widespread demands for customer withdrawals or other needs of financial institutions for immediate liquidity may exceed the Western Districtcapacity of Texas.

These factors could include, among others, events such as liquidity constraints or failures, the ability to perform obligations under various types of financial, credit or liquidity agreements or arrangements, disruptions or instability in the financial services industry or financial markets, or concerns or negative expectations about the prospects for companies in the financial services industry.
The results of events or concerns that involve one or more of these factors could include a variety of material and adverse impacts on the Company’s current and former directors. On September 13, 2021,projected business operations and the Court partially grantedCompany’s financial condition and partially denied motionsresults of operations. These risks include, but may not be limited to, dismiss filed bythe following:

Any decline in available funding or access to cash and liquidity resources could, among other risks, adversely impact the plaintiffsCompany’s ability to meet operating expenses or other obligations, financial or otherwise, result in breaches of the Company’s financial and/or contractual obligations, or result in violations of federal or state wage and hour laws. In addition, any further deterioration in the Shareholder Derivative Lawsuit filed a consolidated complaint alleging (i) breaches of fiduciary duties, (ii) unjust enrichment and (iii) contribution. The plaintiffs did not quantify any alleged damages in their complaint but, in additionmacroeconomic economy or financial services industry could lead to attorneys’ fees and costs, they seek various forms of relief, including (i) damages sustainedlosses or defaults by the Company as a resultCompany’s customers, vendors or suppliers. Any of the alleged misconduct, (ii) punitive damages and (iii) equitable relief in the form of improvements to the Company’s governance and controls. On September 15, 2021, the Court granted the Company's motion to dismiss the complaint in its entirety, without prejudice.
          On November 19, 2021, the Company received a demand letter from a law firm representing one of the purported shareholders of the Company that previously filed the dismissed Shareholder Derivative Lawsuit. The demand letter alleged facts and claims substantially similar to the Shareholder Derivative Lawsuit. The Board of Directors has constituted a committee to evaluate the demand letter and recommend a course of action to the Board of Directors, and the committee has retained counsel to assist with its review. The committee’s review is ongoing.

          We are presently unable to predict the duration, scope or result of the Logan Lawsuitthese impacts, or any other impacts resulting from the factors described above or other related lawsuit or investigation. As of December 31, 2021, no provision was made bysimilar factors, could have material adverse impacts on the Company in connection with this pending lawsuit as the final outcome cannot be reasonably estimated.
          The ongoing Logan LawsuitCompany’s liquidity and any related future litigation give rise to risks and uncertainties that could adversely affect ourtheir current and/or projected business results of operations and financial condition. Such riskscondition and uncertainties include, but are not limited to, uncertainty as to the scope, timing and ultimate outcomeresults of the lawsuit, including the potential impact to the Company in the event of an adverse outcome and on the market price of the Company’s common stock; the costs and expenses of the Logan Lawsuit including legal fees and possible settlement in the event of an adverse outcome; the risk of additional potential litigation or regulatory action arising from matters relating to this lawsuit.
          The outcome of the Logan Lawsuit and any other litigation is necessarily uncertain. We could be forced to expend significant resources in the defense of this lawsuit or future ones, and we may not prevail.
          We maintain director and officer insurance; however, our insurance coverage is subject to certain exclusions (including, for example, any required SEC disgorgement or penalties) and we are responsible for meeting certain deductibles under the policies. Moreover, we cannot assure you that our insurance coverage will adequately protect us from claims made in the Logan Lawsuit. Further, as a result of the pending litigation and investigation the costs of insurance may increase and the availability of coverage may decrease. As a result, we may not be able to maintain our current levels of insurance at a reasonable cost, or at all.operations.
Risks Related to Customers, Suppliers and Competition
Reliance upon a few large customers may adversely affect our revenue and operating results.
The majority of our revenue is generated from our hydraulic fracturing services. Due to the large percentage of our revenue historically derived from our hydraulic fracturing services with recurring customers and the limited availability of our fracturing units, we have had some degree of customer concentration. Our top ten customers represented approximately 91.4%85.5%, 97.3%91.2% and 95.5%91.4% of our consolidated revenue for the years ended December 31, 2021, 20202023, 2022 and 2019,2021, respectively. It is likely that we will depend on a relatively small number of customers for a significant portion of our revenue in the future. If a major customer fails to pay us, revenue would be impacted and our operating results and financial condition could be harmed.
Additionally, if we were to lose any material customer, we may not be able to redeploy our equipment at similar utilization or pricing levels and such loss could have an adverse effect on our business until the equipment is redeployed at similar utilization or pricing levels.
One customer, Pioneer,Endeavor Energy Resources and XTO Energy accounted for 54.2%19.7% and 18.2%, respectively, of our revenue for the year ended December 31, 2021. The revenue generated from2023. If either of these customers were to significantly reduce or discontinue our relationship with Pioneer is largely derived from pressure pumping and related services, provided pursuant to the Pressure Pumping Services Agreement (the "Pioneer Services Agreement"). Although the Pioneer Services Agreement provides for the provision of services for a term of up to 10 years, Pioneer has the right to terminate the Pioneer Services Agreement in its sole discretion, in whole or part, effective as of December 31 of each of the calendar years of 2022, 2024 and 2026. While management believes our relationship with Pioneer will continue beyond December 31, 2022, if Pioneer elects to terminate the Pioneer Services Agreement effective December 31, 2022, or seeks to renegotiate the terms on which we provide services to Pioneer, it could have a material adverse effect on our financial condition, results of operations and cash flows. There have been many recent mergers and acquisitions in the oil and gas industry.
19


In October 2023, Pioneer entered into a merger agreement with Exxon Mobil Corporation.
Mergers and acquisitions involving our customers could negatively impact our future business with them or positively impact our business by providing us access to potential new customers.
We face significant competition that may cause us to lose market share, and competition in our industry has intensified during the industry downturn.
The oilfield servicesservice industry is highly competitive and has relatively few barriers to entry. The principal competitive factors impacting sales of our services are price, reputation and technical expertise, equipment and service quality and health and safety standards. The market is also fragmented and includes numerous small companies capable of competing effectively in our markets on a local basis, as well as several large companies that possess substantially greater financial and other resources than we do. Our larger competitors’ greater resources could allow those competitors to compete more effectively than we can. For instance, our larger competitors may offer services at below‑market prices or bundle ancillary services at no additional cost to our customers. We compete with large national and multi‑national companies that have longer operating histories, greater financial, technical and other resources and greater name recognition than we do. Several of our competitors provide a broader array of services and have a stronger presence in more geographic markets. In addition, we compete with several smaller companies capable of competing effectively on a regional or local basis.
Some jobs are awarded on a bid basis, which further increases competition based on price. Pricing is often the primary factor in determining which qualified contractor is awarded a job. The competitive environment may be further intensified by tighter emissions standards in the energy industry and mergers and acquisitions among oil and natural gas companies or other events that have the effect of reducing the number of available customers. As a result of competition, we may lose customers or customer work and lose market share or be unable to maintain or increase prices for our present services or to acquire additional business opportunities, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.
Our competitors may be able to respond more quickly to new or emerging technologies and services and changes in customer requirements. The amount of equipment available may exceed demand, which could result in active price competition. In addition, some exploration and productionE&P companies have commenced completing their wells using their own hydraulic fracturing equipment and personnel. Any increase in the development and utilization of in‑house fracturing capabilities by our customers could decrease the demand for our services and have a material adverse impact on our business.
Pressure on pricing for our services resulting from the industry downturn has impacted, and may continue to impact, our ability to maintain utilization and pricing for our services or implement price increases. During periods of declining pricing for our services, we may not be able to reduce our costs accordingly, which could further adversely affect our results of operations.
19



Also, we may not be able to successfully increase prices without adversely affecting our utilization levels. The inability to maintain our utilization and pricing levels, or to increase our prices as costs increase, could have a material adverse effect on our business, financial condition and results of operations.
Furthermore, competition among oilfield servicesservice and equipment providers is affected by each provider’s reputation for safety and quality. We cannot assure that we will be able to maintain our competitive position.
We are exposed to the credit risk of our customers, and any material nonpayment or nonperformance by our customers could adversely affect our business, results of operations and financial condition.
We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers. 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 a material adverse effect on our business, results of operations and financial condition. In weak economic environments, we may experience increased delays and failures to pay due to, among other reasons, a reduction in our customers’ cash flow from operations and their access to the credit markets or other sources of capital. The unpredictable nature of oil and gas prices in recent years and the economic disruption from the COVID-19 pandemicother factors may have negatively impacted the financial condition and liquidity of some of our customers, and future declines or continued volatility could impact their ability to meet their financial obligations to us. If our customers delay paying or fail to pay us a significant amount of our outstanding receivables, it could have a material adverse effect on our liquidity, results of operations, and financial condition.
Our business depends upon the ability to obtain specialized equipment, parts and key raw materials, including sand and chemicals, from third‑party suppliers, and we may be vulnerable to delayed deliveries and future price increases.
We purchase specialized equipment, parts and raw materials (including, for example, frac sand, chemicals and fluid ends) from third party suppliers and affiliates. In some cases, our customers are responsible for supplying necessary raw
20


materials (including frac sand), parts and/or equipment. At times during the business cycle, there is a high demand for hydraulic fracturing and other oilfield services and extended lead times to obtain equipment and raw materials needed to provide these services. For example, in 2021 we have seenand 2022, there was significant disruption in supply chains around the world caused by the COVID-19 pandemic that have impacted our operations. Should our current suppliers (or our customers’ suppliers where applicable) be unable or unwilling to provide the necessary equipment, parts or raw materials or otherwise fail to deliver the products timely and/or in the quantities required, any resulting delays in the provision of our services could have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, future price increases for this type of equipment, parts and raw materials could negatively impact our ability to purchase new equipment, to update or expand our existing fleets, to timely repair equipment in our existing fleets or meet the current demands of our customers.
We may be required to pay fees to certain of our sand suppliersSand Suppliers based on minimum volumes under long-term contracts regardless of actual volumes received.
We enter into purchase agreements with sand suppliers (the "the Sand suppliers")Suppliers to secure supply of sand in the normal course of our business. The agreements with the Sand suppliersSuppliers require that we purchase minimum volume of sand, based primarily on a certain percentage of our sand requirements from our customers or in certain situations based on predetermined fixed minimum volumes, otherwise certain penalties (shortfall fees) may be charged. The shortfall fee represents liquidated damages and is either a fixed percentage of the purchase price for the minimum volumes or a fixed price per ton of unpurchased volumes. Our current agreements with Sand suppliersSuppliers expire at different times prior to December 31, 2025.
Disruption of our supply chain could adversely impact our ability to provide our services.
Our suppliers use multiple forms of transportation to bring their products to market, including truck, ocean and air-cargo shipments. Disruption to the timely supply of raw materials, parts and finished goods or increases in the cost of transportation services, including due to general inflationary pressures, cost of fuel and labor, labor disputes, governmental regulation or governmental restrictions limiting specific forms of transportation, could have an adverse effect on our ability to provide our services, which would adversely affect our results of operations, cash flows and financial position.
Risks Related to Employees
We rely on a few key employees whose absence or loss could adversely affect our business.
20



Many key responsibilities within our business have been assigned to a small number of employees. The loss of their services could adversely affect our business. In particular, the loss of the services of one or more members of our executive team, such as our Chief Executive Officer, President and Chief Operating Officer, Chief Financial Officer, Chief Accounting Officer, Chief Commercial Officer and General Counsel could disrupt our operations. We do not maintain "key person" life insurance policies on any of our employees. As a result, we are not insured against any losses resulting from the death of our key employees.
If we are unable to employ a sufficient number of skilled and qualified workers, our capacity and profitability could be diminished and our growth potential could be impaired.
The delivery of our services requires skilled and qualified workers with specialized skills and experience who can perform physically demanding work. As a result of the volatility of the oilfield servicesservice industry and the demanding nature of the work, workers may choose to pursue employment in fields that offer a less challenging work environment at wage rates that are competitive. Our ability to be productive and profitable will depend upon our ability to employ and retain skilled workers. In addition, our ability to expand our operations depends in part on our ability to increase the size of our skilled workers. As a result of the COVID-19 pandemic,physical nature of our operations, we have experienced difficulties in attracting and retaining skilled workers. If demand for our services increases, we may experience difficulty in hiring or re-hiring skilled and unskilled workers in the future to meet that demand. At times, the demand for skilled workers in our geographic areas of operations is high, and the supply is limited. As a result, competition for experienced oilfield servicesservice personnel is intense, and we face significant challenges in competing for crews and management with large and well‑established competitors. A significant increase in the wages paid by competing employers could result in a reduction of our skilled labor force, increases in the wage rates that we must pay, or both. Furthermore, if we are unable to adjust wages to account for rapidly rising inflationary cost, there could be a reduction in the available skilled labor force we could attract or retain. If any of these events were to occur, our capacity and profitability could be diminished and our growth potential could be impaired.
Risks Related to Regulatory Matters
We are subject to environmental laws and regulations, and future compliance, claims, and liabilities relating to such matters may have a material adverse effect on our results of operations, financial position or cash flows.
The nature of our operations, including the handling, storing, transporting and disposing of a variety of fluids and substances, including hydraulic fracturing fluids, which can contain substances such as hydrochloric acid, and other regulated substances, air emissions and wastewater discharges exposes us to some risks of environmental liability, including the release of pollutants from oil and natural gas wells and associated equipment to the environment. The cost of compliance with these laws can be significant. Failure to properly handle, transport or dispose of these materials or
21


otherwise conduct our operations in accordance with these and other environmental laws could expose us to substantial liability for administrative, civil and criminal penalties, cleanup and site restoration costs and liability associated with releases of such materials, damages to natural resources and other damages, as well as potentially impair our ability to conduct our operations. Such liability is commonly on a strict, joint and several liability basis, without regard to fault. Liability may be imposed as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, prior operators or other third parties. Neighboring landowners and other third parties may file claims against us for personal injury or property damage allegedly caused by the release of pollutants into the environment. Environmental laws and regulations have changed in the past, and they may change in the future and become more stringent. For example, following the election of President Biden and Democratic control in both houses of Congress, President Bidencurrent government has made climate change a focus of hisits administration. For more information, see our risk factor titled, “Our and our customers’ operations are subject to a series of risks arising out of the threat of climate change that could result in increased operating costs, limit the areas in which oil and natural gas production may occur, and reduce demand for the products and services we provide.” Separately, current and future claims and liabilities may have a material adverse effect on us because of potential adverse outcomes, defense costs, diversion of management resources, unavailability of insurance coverage and other factors. The ultimate costs of these liabilities are difficult to determine and may exceed any reserves we may have established. If existing environmental requirements or enforcement policies change, we may be required to make significant unanticipated capital and operating expenditures.
Our and our customers’ operations are subject to a series of risks arising out of the threat of climate change that could result in increased operating costs, limit the areas in which oil and natural gas production may occur, and reduce demand for the products and services we provide.
The threat of climate change continues to attract considerable attention in the United States and in foreign countries. 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 as well as to restrict or eliminate future GHG emissions. As a result, our
21



operations as well as the operations of our oil and natural gas exploration and productionE&P customers are subject to a series of regulatory, political, litigation, and financial risks associated with the production and processing of fossil fuels and emission of GHGs.
In the United States, no comprehensive climate change legislation has been implemented at the federal level. However,level, though recently passed laws such as the IRA 2022 advance numerous climate-related objectives. Additionally, following the U.S. Supreme Court finding that GHG emissions constitute a pollutant under the CAA, the EPA has adopted regulations that, among other things, establish construction and operating permit reviews for GHG 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, implement New Source Performance Standards directing the reduction of certain pollutants from certain new, modified, or reconstructed facilities in the oil and natural gas sector, and together with the DOT, implementing GHG emissions limits on vehicles manufactured for operation in the United States. In September 2020, the Trump Administrationgovernment revised prior regulations to rescind certain methane standards and remove the transmission and storage segment from the oil and natural gas source category and rescinded the methane-segmentssegments from the source category for certain regulations. However, subsequently, the U.S. Congress approved, and President Bidenthe president signed into law, a resolution under the Congressional Review Act to repeal the September 2020 revisions to the methane standards, effectively reinstating the prior standards. Additionally, in November 2021, the EPA issuedfinalized a proposed rule that if finalized, would establish OOOO(b)established OOOOb more stringent new source and OOOO(c)OOOOc first-time existing source standards of performance for methane and volatile organic compound emissions for oil and gas facilities. Operators of affected facilitiesUnder the final rule, states will have two years to comply with specificprepare and submit their plans to impose methane emissions controls on existing sources. The presumptive standards of performance to includeunder the final rule are generally the same for both new and existing sources, including enhanced leak detection using optical gas imaging and subsequent repair requirement,equipment, and reduction of emissions by 95% through capture and control systems. The EPArule also revises requirements for fugitive emissions monitoring and repair as well as equipment leaks and the frequency of monitoring surveys, establishes a "super-emitter" response program to timely mitigate emissions events as detected by governmental agencies or qualified third parties, triggering certain investigation and repair requirements, and provides additional options for the use of advanced monitoring to encourage the deployment of innovative technologies to detect and reduce methane emissions. It is likely that these requirements will be subject to legal challenge. Failure to comply with these new methane rules may result in substantial fines and penalties for non-compliance, as well as injunctive relief. Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on such areas such as GHG cap and trade programs, carbon taxes, reporting and tracking programs, and restriction of emissions. At the international level, the United Nations-sponsored Paris Agreement, requires member states to submit non-binding, individually-determined reduction goals known as NDCs every five years after 2020. Following the president’s executive order in January 2021, the United States rejoined the Paris Agreement and, in April 2021, established a goal of reducing economy-wide net GHG emissions 50-52% below 2005 levels by 2030. Additionally, at the 26th Conference of the Parties ("COP26") in Glasgow in November 2021, the United States and the European Union jointly announced the launch of the Global Methane Pledge; an initiative committing to a collective goal of reducing global methane emissions by at least 30% from 2020 levels by 2030, including "all feasible reductions" in the energy sector. At the 27th Conference of the Parties in November 2022, countries reiterated the agreements from COP26 and were called upon to accelerate efforts toward the phase out of inefficient fossil fuel subsidies. The U.S. also announced, in conjunction with the European Union and other partner countries, that it would develop standards for monitoring and reporting methane emissions to help create a market for low methane-intensity natural gas. At the 28th Conference of the Parties (“COP28”) in December 2023, countries reached an agreement to tackle climate change by transitioning away from fossil fuels in energy systems in a just, orderly and equitable manner. The agreement set global targets to triple the capacity of renewable energy like wind and solar power, and to double the rate of energy efficiency improvements, both by 2030, and also called on countries to accelerate low- and zero-emission technologies like carbon capture and storage. Although no firm commitment or timeline to transition away from fossil fuels was made at COP28, there can be no guarantees that countries will not seek to implement plans to issue a supplemental proposal in 2022 containing additional requirements not includedtransition away from fossil fuels in the November 2021 proposed rulefuture. Additionally, the agreements could result in increased pressure among financial institutions and anticipatesvarious stakeholders to reduce or otherwise impose more stringent limitations on funding for and increase potential opposition to the issuanceproduction and use of a final rule byfossil fuels. However, the endimpacts of the year.these actions are unclear at this time.

Governmental, scientific, and public concern over the threat of climate change arising from GHG emissions has resulted in increasing political risks in the United States, including climate-change-related pledges made by certain
22


candidates for public office. On January 27, 2021, President Bidenthe president issued an executive order that commits to substantial action on climate change, calling for, among other things, the increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry, and an increased emphasis on climate-related risk across government agencies and economic sectors. The executive order also suspendssuspended the issuance of new leases for oil and gas development on federal land; for more information, see our risk factor titled "Federal and state legislative and regulatory disclosure titled “Regulation of Hydraulic Fracturinginitiatives relating to hydraulic fracturing could result in increased costs and Related Activities. additional operating restrictions or delays."
Other actions that the Biden Administrationcurrent government may take include the imposition of more restrictive requirements for the development of pipeline infrastructure or LNGliquefied natural gas export facilities, or more restrictive GHG emissions limitations for oil and gas facilities. LitigationFor example, on January 26, 2024, the president announced a temporary pause on pending decisions on new exports of LNG to countries that the United States does not have free trade agreements with, pending Department of Energy review of the underlying analyses for authorizations. The pause is intended to provide time to integrate certain considerations, including potential energy cost increases for consumers and manufacturers and the latest assessment of the impact of GHG emissions, to ensure adequate guards against health risks are in place.Litigation risks are also increasing as a number of cities and other local governmentsparties have sought to bring suit against certain oil and natural gas companies operating in the United States in state or federal court, alleging among other things, that such companies created public nuisances by producing fuels that contributed to climate change or that such companies have been aware of the adverse effects of climate change but failed to adequately disclose those impacts to their investors or customers.
There are also increasing financial risks for companies in the fossil fuel sector as shareholders currently invested in fossil-fuel energy companies concerned about the potential effects of climate change may elect in the future to shift some or all of their investments into non-fossil fuel related sectors. Institutional lenders who provide financing to fossil-fuel energy companies also have become more attentive to sustainable lending practices and some of them may elect not to provide funding for fossil fuel energy companies. For example, at COP26, the Glasgow Financial Alliance for Net Zero ("GFANZ"("GFANZ") announced that commitments from over 450 firms across 45 countries had resulted in over $130 trillion in capital committed to net zero goals. The various sub-alliances of GFANZ generally require participants to set short-term, sector-specific targets to transition their financing, investing, and/or underwriting activities to net zero emissions by 2050. There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. In late 2020, the Federal Reserve announced that it has joined the Network for Greening the Financial System ("NGFS"("NGFS"), a consortium of financial regulators focused on addressing climate-related risks in the financial sector. Subsequently, the Federal Reserve has issued a statement in support of the efforts of the NGFS to identify key issues and potential solutions for the climate-related challenges most relevant to central banks and supervisory authorities. Limitation of investments in and financings for fossil fuel energy companies could result in the restriction, delay or cancellation of drilling programs or development or production activities. In January 2023, the Federal Reserve launched a pilot climate scenario analysis exercise, with six of the United States’ largest banks participating to enhance the ability of firms and supervisors to measure and manage climate-related financial risk. Additionally, the United States SecuritiesSEC released a final rule on climate-related disclosures on March 6, 2024, requiring the disclosure of certain climate-related risks and Exchange Commission has announced an intentionfinancial impacts, as well as GHG emissions. Large accelerated filers will be required to promulgate rules requiringincorporate the applicable climate-related disclosures into their filings beginning in fiscal year 2025, with additional requirements relating to the disclosure of Scope 1 and 2 GHG emissions, if material, and attestation reports for certain large accelerated filers subsequently phasing in. Similarly, certain states have enacted or are otherwise considering disclosure requirements for certain climate-related risks. While we are still assessing our obligations under the rule, enhanced climate-related disclosure requirements could increase our operating costs and lead to reputational or other harm with customers, regulators, or other stakeholders to the extent our disclosures do not meet their own standards or expectations. Consequently, we are also exposed to increased litigation risks relating to alleged climate-related damages resulting from our operations, statements alleged to have been made by us or others in our industry regarding climate disclosures. Although the form and substance of these requirements is not yet known, this may resultchange risks, or in additional costs to complyconnection with any future disclosures we may make regarding reported emissions, particularly given the inherent uncertainties and estimation required with respect to calculating and reporting GHG emissions. We also cannot predict how financial institutions and investors might consider any information disclosed under any such disclosure requirements.requirements when making investment decisions, and as a result it is possible that we could face increases with respect to the costs of, or restrictions imposed on, our access to capital.
The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other regulatory initiatives that impose more stringent standards for GHG emissions from the oil and natural gas sector or otherwise restrict the areas in which this sector may produce oil and natural gas or generate GHG emissions could result in increased costs of compliance or costs of consuming, and thereby reduce demand for, oil and natural gas, which could reduce demand for our services and products. Additionally, political, litigation and financial risks may result in our oil and natural gas customers restricting or cancelling production activities, incurring liability for infrastructure damages as a result of climatic changes, or
23



impairing their ability to continue to operate in an economic manner, which also could reduce demand for our services and products. One or more of these developments could have a material adverse effect on our business, financial condition and results of operationoperations.
Moreover, climate change may result in various physical risks, such as the increased frequency or intensity of extreme weather events or changes in the meteorological and hydrological patterns, that could adversely impact us, our customers’ and our suppliers’ operations. Such physical risks may result in damage to our customers’ facilities or otherwise adversely impact our operations, such as if facilities are subject to water use curtailments in response to drought, or demand for our customers’ products, such as to the extent warmer winters reduce the demand for energy for heating purposes, which may ultimately reduce demand for the products and services we provide. Such physical risks may also impact our suppliers, which may adversely affect our ability to provide our products and services. Extreme weather conditions can interfere with our operations and increase our costs, and damage resulting from extreme weather may not be fully insured.

Federal and state legislative and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional operating restrictions or delays.
Our hydraulic fracturing operations are a significant component of our business, and it is an important and common practice that is used to stimulate production of hydrocarbons, particularly oil and natural gas, from tight formations, including shales. The process, which involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate production, is typically regulated by state oil and natural gas commissions. However, federal agencies have asserted regulatory authority over certain aspects of the process. For example, the EPA has previously issued a series of rules under the CAA that establish new emission control requirements for emissions of volatile organic compounds and methane from certain oil and natural gas production and natural gas processing operations and equipment. Separately, the BLM finalized a rule governing hydraulic fracturing on federal lands but this rule was subsequently rescinded. Although several of these rulemakings have been rescinded, modified or subjected to legal challenges, new or more stringent regulations may be promulgated by the Biden Administration.government. For example, inthe BLM recently proposed a rule that would limit flaring from well sites on federal lands, as well as allow the delay or denial of permits if BLM finds that an operator’s methane waste minimization plan is insufficient. In January 2021, President Bidenthe president issued an executive order suspending new leasing activities, but not operations under existing leases, for oil and gas exploration and productionE&P on non-Indian federal lands pending completion of a comprehensive review and reconsideration of federal oil and gas permitting and leasing practices that take into consideration potential climate and other impacts associated with oil and gas activities on such lands and waters. Although the federal court for the Western District of Louisiana issuedleasing pause was effectively halted by a preliminarypermanent injunction against the leasing pause,in August 2022, in response to the executive order, the DOI issued a report recommending various changes to the federal leasing program, though many such changes would require Congressional action. In July 2023, the BLM proposed a rule to update the fiscal terms of federal oil and gas leases, which would increase fees, rents, royalties, and bonding requirements. The rule would also add new criteria for BLM to consider when determining whether to lease nominated land, including the presence of important habitats or wetlands, the presence of historical properties or sacred sites, and recreational use of the land. BLM anticipates a final action on the proposal in Spring 2024. As a result, we cannot predict the final scope of regulations or restrictions that may apply to oil and gas operations on federal lands. However, any regulations that ban or effectively ban such operations may adversely impact demand for our products and services. Further, legislation to amend the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing (except when diesel fuels are used) from the definition of “underground injection” and require federal permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to require disclosure of the chemical constituents of the fluids used in the fracturing process, have been proposed in recentprevious sessions of Congress. Several states and local jurisdictions in which we or our customers operate also have adopted or are considering adopting regulations that could restrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating standards and/or require the disclosure of the composition of hydraulic fracturing fluids.
Federal and state governments have also investigated whether the disposal of produced water into underground injection wells has caused increased seismic activity in certain areas. In response to concerns regarding induced seismicity, regulators in some states have imposed, or are considering imposing, additional requirements in the permitting of produced water disposal wells or otherwise to assess any relationship between seismicity and the use of such wells. For example, Oklahoma has issued rules for wastewater disposal wells in 2014 that imposed certain permitting and operating restrictions and reporting requirements on disposal wells in proximity to faults and also, from time to time, has implemented plans directing certain wells where seismic incidents have occurred to restrict or suspend disposal well operations. In particular, the Oklahoma Corporation Commission released well completion seismicity guidelines for operators in the SCOOP and STACK require hydraulic fracturing operations to be suspended following earthquakes of certain magnitudes in the vicinity. In addition, the Oklahoma Corporation Commission’s Oil and Gas Conservation Division has previously issued an order limiting future increases in the volume of oil and natural gas wastewater injected into the ground in an effort to reduce the number of earthquakes in the state. The TRRC has adopted similar rules and, in September 2021, issued a notice to disposal well operators in the Gardendale Seismic Response
24



Area near Midland, Texas to reduce daily injection volumes following multiple earthquakes above a 3.5 magnitude over an 18 month period. The notice also required disposal well operators to provide injection data to TRRC staff to further analyze seismicity in the area. Subsequently, the TRRC ordered the indefinite suspension of all deep oil and gas produced water injection wells in the area, effective December 31, 2021. The Gardendale Seismic Response area has since been expanded in response to an additional earthquake in December 2022, covering 17 additional wells. In December 2023, a further 23 deep disposal well permits were suspended in the Northern Culberson-Reeves Seismic Response Area. While we cannot predict the ultimate outcome of these actions, any action that temporarily or permanently restricts the availability of disposal capacity for produced water or other oilfield fluids may increase our customers’ costs or require them to suspend operations, which may adversely impact demand for our products and servicesservices.
Increased regulation of hydraulic fracturing and related activities could subject us and our customers to additional permitting and financial assurance requirements, more stringent construction specifications, increased monitoring, reporting and recordkeeping obligations, and plugging and abandonment requirements. New requirements could result in increased operational costs for us and our customers, and reduce the demand for our services.
24


Increasing trucking regulations may increase our costs and negatively impact our results of operations.
In connection with our business operations, including the transportation and relocation of our hydraulic fracturing equipment and shipment of frac sand, we operate trucks and other heavy equipment. As such, we operate as a motor carrier in providing certain of our services and therefore are subject to regulation by the DOT and by various state agencies. These regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier operations, driver licensing, insurance requirements, financial reporting and review of certain mergers, consolidations and acquisitions, and transportation of hazardous materials. Our trucking operations are subject to possible regulatory and legislative changes that may increase our costs. 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 or work in any specific period, onboard black box recorder device requirements or limits on vehicle weight and size.
Interstate motor carrier operations are subject to safety requirements prescribed by the DOT. To a large degree, intrastate motor carrier operations are subject to state safety regulations that mirror federal regulations. Matters such as the weight and dimensions of equipment are also subject to federal and state regulations. 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.
Certain motor vehicle operators require registration with the DOT. This registration requires an acceptable operating record. The DOT periodically conducts compliance reviews and may revoke registration privileges based on certain safety performance criteria that could result in a suspension of operations.
Increased attention to environmental, social and governance (“ESG”)ESG matters, conservation measures, commercial development and technological advances could reduce demand for oil and natural gas and our services.
Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil and natural gas, increased attention to climate change and other ESG matters, and technological advances in fuel economy and energy generation devices could reduce demand for oil and natural gas, resulting in reduced demand for oilfield services. The impact of the changing demand for oil and natural gas services and products may have a material adverse effect on our business, financial condition, results of operations and cash flows.
The commercial development of economically‑viable alternative energy sources and related products (such as electric vehicles, wind, solar, geothermal, tidal, fuel cells and biofuels) could have a similar effect. The IRA 2022 appropriates significant federal funding for renewable energy initiatives, which could accelerate the use and commercial viability of alternative energy sources and decrease demand for oil and natural gas. The IRA 2022 has incentivized the further development of and investment in clean energy through the use of tax credits, and future legislation could expand these benefits for alternative energy sources. In addition, certain U.S. federal income tax deductions currently available with respect to oil and natural gas exploration and development, including the allowance of percentage depletion for oil and natural gas properties, may be eliminated as a result of proposed legislation. Any future decreases in the rate at which oil and natural gas reserves are discovered or developed, whether due to the passage of legislation, increased governmental regulation leading to limitations, or prohibitions on exploration and drilling activity, including hydraulic fracturing, or other factors, could have a material adverse effect on our business and financial condition, even in a stronger oil and natural gas price environment.
25



Moreover, while we may create and publish voluntary disclosures regarding ESG matters from time to time, certain statements in those voluntary disclosures may be based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters. Additionally, we may announce various targets or product and service offerings in an attempt to improve our ESG profile. However, we cannot guarantee that we will be able to meet any such targets or that such targets or offerings will have the intended results on our ESG profile, including but not limited to as a result of unforeseen costs, consequences or technical difficulties associated with such targets or offerings. Also, despite any voluntary actions, we may receive pressure from certain investors, lenders or other groups to adopt more aggressive climate or other ESG-related goals or policies, but we cannot guarantee that we will be able to implement such goals because of potential costs or technical or operational obstacles.
In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings and recent activism directed at shifting funding away from companies with energy-related assets could lead to increased negative investor sentiment toward us and our industry and to the diversion of investment to other industries, which could have a negative impact on our stock price and our access to and costs of capital. Additionally, to the extent ESG matters negatively impact our
25


reputation, we may not be able to compete as effectively to recruit or retain employees, which may adversely affect our operations.
Certain of our completion services, particularly our hydraulic fracturing services, are substantially dependent on the availability of water. Restrictions on our or our customers’ ability to obtain water may have an adverse effect on our financial condition, results of operations and cash flows.
Water is an essential component of unconventional shale oil and natural gas production during both the drilling and hydraulic fracturing processes. Over the past several years, certain of the areas in which we and our customers operate have experienced extreme drought conditions and competition for water in such areas is growing. In addition, some state and local governmental authorities have begun to monitor or restrict the use of water subject to their jurisdiction for hydraulic fracturing to ensure adequate local water supply. For instance, some states require E&P companies to report certain information regarding the water they use for hydraulic fracturing and to monitor the quality of groundwater surrounding some wells stimulated by hydraulic fracturing. Generally, our water requirements are met by our customers from sources on or near their sites, but there is no assurance that our customers will be able to obtain a sufficient supply of water from sources in these areas. Our or our customers’ inability to obtain water from local sources or to effectively utilize flowback water could have an adverse effect on our financial condition, results of operations and cash flows.
Risks Related to our Tax Matters
Our ability to use our net operating loss carryforwardsNOLs may be limited.
The Tax Cuts and Jobs Act (the "TCJA") included a reduction to the maximum deduction allowed for net operating losses generated in tax years after December 31, 2017, and the elimination of carrybacks of net operating losses. Under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, which modified the TCJA, U.S. federal net operating loss carryforwards ("NOLs") generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such NOLs in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. As of December 31, 2021,2023, we had approximately $408.0$296.6 million of U.S. federal NOLs, some of which will begin to expire in 2035. Approximately $219.5$87.7 million of our U.S. federal NOLs relate to pre-2018 periods. As of December 31, 2021,2023, our state net operating losses were approximately $50.1$48.1 million and will begin to expire in 2024.2030.
Utilization of these NOLs depends on many factors, including our future income, which cannot be assured. In addition, Section 382 ("Section 382") of the Internal Revenue Code of 1986, as amended (the "Code"), generally imposes an annual limitation on the amount of taxable income that may be offset by NOLs when a corporation has undergone an "ownership change" (as determined under Section 382). Generally, a change of more than 50% in the ownership of a corporation’s stock, by value, over a three‑year period constitutes an ownership change for U.S. federal income tax purposes. Any unused annual limitation may, subject to certain limitations, be carried over to later years. We may experience ownership changes, which may result in annual limitation under Section 382 determined by multiplying the value of our stock at the time of the ownership change by the applicable long‑term tax‑exempt rate as defined in Section 382, increased under certain circumstances as a result of recognizing built‑in gains in our assets existing at the time of the ownership change. The limitations arising from ownership changes may prevent utilization of our NOLs prior to their expiration. Future ownership changes or regulatory changes could further limit our ability to utilize our NOLs. To the extent we are not able to offset our future income with our NOLs, this could adversely affect our operating results and cash flows if we attain profitability.
26



Changes to applicable tax laws and regulations or exposure to additional income tax liabilities could adversely affect our operating results and cash flows.
We are subject to various complex and evolving U.S. federal, state and local tax laws. 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. Any significant variance in our interpretation of current tax laws or a successful challenge of one or more of our tax positions by the Internal Revenue Service or other tax authorities could increase our future tax liabilities and adversely affect our operating results and cash flows.
Risks Inherent to an Investment in our Common Stock
We are subject to certain requirements of Section 404 of the Sarbanes-Oxley Act ("Section 404"). If we or our auditors identify and reporthave identified a material weaknesses in internal control over financial reporting, our investors may lose confidence in our reported information and our stock price may be negatively affected.
          We are required to comply with certain provisions of Section 404, which requires that we document and test our internal control over financial reporting and issue our management’s assessment of our internal control over financial reporting. This section also requires that our independent registered public accounting firm issue an attestation report on such internal control.
          If we or our auditors identify and report material weaknessesweakness in our internal control over financial reporting with regard to segregation of certain accounting duties and management review controls. We may identify additional material weaknesses in the accuracy and timelinessfuture or otherwise fail to maintain an effective system of the filinginternal controls, which may result in material misstatements of our annual and quarterly reportsfinancial statements, cause us to fail to meet our reporting obligations, investors may be materially adversely affected and could cause investors to lose confidence in our reported financial information, which could havereporting, and our stock price may decline as a negative effect onresult or cause us to fail to meet our reporting obligations.
In connection with the trading pricepreparation of our common stock. In addition,financial statements for the year ended December 31, 2023, we identified a material weakness in the effectiveness of our internal control over financial reporting, resulting from our failure to maintain adequate segregation of duties or sufficient compensating management review controls to effectively mitigate an inadequate system access control configuration in our accounting system in which manual journal entry approvers can modify the entries before posting. This deficiency is solely related to manual journal entries and has no impact on system-generated journal entries flowing through our accounting system and other feeder systems. Due to this control deficiency, other manual-dependent controls were deemed ineffective. This material weakness could result in an increased chancea misstatement of fraud and the loss of customers, reduce our ability to obtain financing and
26


require additional expenditures to comply with these requirements, each of which could haveaforementioned account balances or disclosures that would result in a material adverse effectmisstatement of the annual or interim consolidated financial statements that would not be prevented or detected. Notwithstanding such material weakness, our management believes that our financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, our business, financial condition, prospects,position, results of operations and cash flows.flows for the periods presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

We have taken steps to remediate this material weakness and plan to take additional steps to further improve our overall internal control environment. We have implemented a segregation of duties conflict process by limiting access of certain employees of the Company who are owners of management review controls; tested whether this access resulted in any inappropriate entries being recorded or revised and concluded that no such instances occurred; implemented a technical solution to ensure that access to our system of records adequately limits incompatible duties and strengthened our monitoring and review controls over journal entry processing; and implemented control activities related to additional independent reviews of manual entries posted in the accounting system and are currently evaluating additional procedures to further strengthen the Company’s overall segregation of duties. These actions are subject to ongoing management review and the oversight of our Audit Committee and Board.

The material weakness described above or any newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to remediate the control deficiencies that led to the material weakness in our internal control over financial reporting described above or to avoid potential future material weaknesses.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. If we are unable to successfully remediate our existing or any future material weakness in our internal control over financial reporting, or identify any additional material weaknesses that may exist, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, we may be unable to prevent fraud, investors may lose confidence in our financial reporting, and our stock price may decline as a result.

Certain provisions of our certificate of incorporation, and bylaws, as well as Delaware law, may discourage acquisition bids or merger proposals, which may adversely affect the market price of our common stock.
Our certificate of incorporation authorizes our board of directors (the "Board") to issue preferred stock without shareholder approval. If our Board elects to issue preferred stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our shareholders, including:
27



limitations on the removal of directors;
limitations on the ability of our shareholders to call special meetings;
advance notice provisions for shareholder proposals and nominations for elections to the Board to be acted upon at meetings of shareholders;
providing that the Board is expressly authorized to adopt, or to alter or repeal our bylaws; and
establishing advance notice and certain information requirements for nominations for election to our Board or for proposing matters that can be acted upon by shareholders at shareholder meetings.
Our business could be negatively affected as a result of the actions of activist shareholders.
Publicly traded companies have increasingly become subject to campaigns by investors seeking to increase shareholder value by advocating corporate actions such as financial restructuring, increased borrowing, special dividends, stock repurchases, sales of assets or even sale of the entire company. Given our shareholder composition and other factors, it is possible such shareholders or future activist shareholders may attempt to effect such changes or acquire control over us. Responding to proxy contests and other actions by such activist shareholders or others in the future would be costly and time-consuming, disrupt our operations and divert the attention of our Board and senior management from the pursuit of business strategies, which could adversely affect our results of operations and financial condition. Additionally, perceived uncertainties as to our future direction as a result of shareholder activism or changes to the composition of the Board may lead to the perception of a change in the direction of our business, instability or lack of continuity which may be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel. If customers choose to delay, defer or reduce transactions with us or transact with our competitors instead of us because of any such issues, then our business, financial condition, revenues, results of operations and cash flows could be adversely affected.
Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our shareholders, which could limit our shareholders’ ability to pursue actions in another judicial forum for disputes with us or our directors, officers, employees or agents.
Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, (the "DGCL"), our certificate of incorporation or our bylaws, or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein.
The exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.
27


The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or similar governing documents has been challenged in legal proceedings, and it is possible that a court could find the choice of forum provisions contained in our certificate of incorporation to be inapplicable or unenforceable, including with respect to claims arising under the U.S. federal securities laws.
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 our certificate of incorporation regarding exclusive forum. This choice of forum provision may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.
The market price of our common stock is subject to volatility.
28



The market price of our common stock could be subject to wide fluctuations in response to, and the level of trading of our common stock may be affected by, numerous factors, many of which are beyond our control. These factors include, among other things, our limited trading volume, the concentration of holdings or our common stock, actual or anticipated variations in our operating results and cash flow, the nature and content of our earnings releases, announcements or events that impact our products, customers, competitors or markets, business conditions in our markets and the general state of the securities markets, volatility in oil and gas prices and the market for energy-related stocks, as well as general economic and market conditions and other factors that may affect our future results, including those described in this report. Significant sales of our common stock, or the expectation of these sales, by significant shareholders, officers or directors could materially and adversely affect the market price of our common stock.
There may be future sales or other dilution of our equity, which may adversely affect the market price of our common stock.
We are not restricted from issuing additional common stock, including securities that are convertible into or exchangeable for, or that represent a right to receive, common stock. In addition, we may issue common stock as consideration in future mergers and acquisitions, as we did in the Silvertip Acquisition. Any issuance of additional shares of our common stock or convertible securities will dilute the ownership interest of our common stockholders. Sales of a substantial number of shares of our common stock or other equity-related securities in the public market, or the perception that these sales could occur, could depress the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our common stock or other equity-related securities would have on the market price of our common stock.
There can be no assurance that our share repurchase program will be fully consummated or that such program will enhance the long-term value of our share price.
On May 17, 2023, the Company's Board approved a share repurchase program that allows the Company to repurchase up to $100 million of the Company's common stock through and including May 31, 2024. There is no obligation for the Company to continue to repurchase or to repurchase any specific dollar amount of stock. The timing, as well as the number and value of shares repurchased under the program, will be determined by the Company at its discretion and will depend on a variety of factors, including management's assessment of the intrinsic value of the Company's common stock, the market price of the Company's common stock, general market and economic conditions, available liquidity, compliance with the Company's debt and other agreements, applicable legal requirements, and other considerations. The Company is not obligated to purchase any shares under the repurchase program, and the program may be suspended, modified, or discontinued at any time without prior notice. The repurchase program could affect the price of our stock and increase volatility in the market. We cannot guarantee that the repurchase program will be fully consummated or that such program will enhance the long-term value of our share price. In addition, repurchase regulations and taxes may add additional payment burden to the Company from our share repurchase program. For example, the current government has proposed increasing the amount of the excise tax from 1% to 4%. However, it is unclear whether such a change in the amount of the excise tax will be enacted and, if enacted, how soon any such change could take effect.

Item 1B. Unresolved Staff Comments.
None.
Item 1C. Cybersecurity.
We have established an Information Security Management System (the “ISMS”), which is integrated into our overall risk management system, to help us achieve our business goals. The ISMS defines our information security risk management approach and specifies the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining and improving a risk assessment framework within the context of our overall business risks. The ISMS also specifies the requirements for implementing security controls designed to meet the needs of individual departments or parts thereof.
Risk Management and Strategy
Our cybersecurity strategy focuses on implementing controls, technologies, and other processes to assess, identify, and manage material cybersecurity risks. We have processes in place designed to assess, identify, manage, and address material cybersecurity threats and incidents, including: annual security awareness training for employees, mechanisms designed to detect and monitor unusual network activity, and containment and incident response tools. Our ISMS is designed to help us identify and manage material risks from cybersecurity threats, and as part of our ISMS, we engage a range of third-party service providers, including assessors, consultants, and auditors, to assist us in these processes. Our risk assessment framework involves an information security risk assessment procedure that helps us identify potential cybersecurity threats and vulnerabilities (including relating to the use of third-party service providers) and then determine strategies to mitigate or counter the threats. As part of this process, we conduct annual penetration testing utilizing a third-party service provider. We have implemented controls designed to identify and mitigate cybersecurity threats associated with our use of third-party service providers. Such providers are subject to security risk assessments at the time of onboarding, contract renewal, and upon detection of an increase in risk profile. We use a variety of inputs in such risk assessments, including information supplied by providers and third parties. In addition, we require our providers to meet appropriate security requirements, controls and responsibilities and investigate security incidents that have impacted our third-party providers, as appropriate. Our Information Technology Director also works with third-party service providers to assess potential cybersecurity threats and determines risk scores based on the likelihood of threats and the potential impacts of the threats, prioritizes risk and determines and recommends to our management controls aimed to counter such threats. We assess third-party cybersecurity controls through a cybersecurity questionnaire and include security and privacy addenda to our contracts where applicable.
We also maintain procedures designed to protect the security of personally identifiable information, and our Privacy Policy provides details regarding the collection, storage, usage, and destruction of data. We require all employees to engage in data-security training upon hire and receive ongoing training thereafter. In the event of an incident, we intend to follow our incident response plan, which outlines the steps to be followed from incident detection to mitigation, recovery and notification, including notifying functional areas (e.g., legal), as well as senior leadership and the Board, as appropriate.
Governance
Management is responsible for assessing, identifying, and managing risks from cybersecurity threats. Our cybersecurity risk management efforts are led by our Information Technology Director, who oversees our cybersecurity activities and is informed about and monitors the prevention, detection, mitigation and remediation of cybersecurity incidents as part of our ISMS. The Information Technology Director is part of the Company’s Security Committee and reports to the Security Committee with respect to emerging cybersecurity incidents deemed to have a moderate or higher business impact, even if immaterial to us. Our Security Committee, comprised of the Information Technology Director, the Chief Financial Officer, the Chief Legal Counsel and the Vice President of Human Resources is ultimately responsible for the implementation of our cybersecurity risk management processes. To facilitate effective oversight, our Security Committee holds discussions on cybersecurity risks, incident trends, and the effectiveness of cybersecurity measures as necessitated by emerging cybersecurity risks. The Security Committee has experience managing enterprises relying on technology and business systems with cybersecurity risks and consults with trusted advisors where appropriate.
The audit committee of our Board is responsible for oversight of risks from cybersecurity threats. The Information Technology Director presents an update on cybersecurity risk management to the audit committee of our Board during quarterly meetings and the audit committee reports to the Board.

Impact of Risks from Cybersecurity Threats
As of the date of this report, though the Company and our service providers have experienced certain cybersecurity incidents, we are not aware of any previous cybersecurity incidents that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations and financial condition. We acknowledge that cybersecurity threats are continually evolving, and the possibility of future cybersecurity incidents remains. Despite the implementation of our cybersecurity processes, our security measures cannot guarantee that a significant cybersecurity attack will not occur. While we devote resources to our security measures designed to protect our systems and information, no security measure is infallible. See Part I, "Item 1A. Risk Factors" of this Annual Report for additional information about the risks to our business associated with a breach or other compromise to our information and operational technology systems.

Overview
Our Business
We are a leading integrated oilfield service company, located in Midland, Texas‑based oilfield services companyTexas, focused on providing innovative hydraulic fracturing, wireline and other complementary oilfield completion services to leading upstream oil and gas companies engaged in the exploration and production (“E&P &P”) of North American oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated longstanding customer relationships with some of the region’s most active and well‑capitalized E&P companies. The Permian Basin is widely regarded as one of the most prolific oil‑producing areas in the United States, and we believe we are one of the leading providers of hydraulic fracturingcompletion services in the region by HHP.region.
Our completion services includes our operating segments comprised of hydraulic fracturing, wireline and cementing operations. Our hydraulic fracturing operations account for approximately 78.5% of our total revenues and operations. Our total available HHPhydraulic horsepower ("HHP") at December 31, 2021 was2023 w 1,423,000as 1,461,500 HHP, which was comprised of 90,000 452,500 HHP of our Tier IV DGBDynamic Gas Blending (“DGB”) dual-fuel equipment, 1,225,000144,000 HHP of FORCESM electric-powered equipment and 865,000 HHP of conventional Tier II equipment and 108,000 HHP of ourequipment. Our DuraStim® electric hydraulic fracturing equipment. Our fleet couldfleets range from approximately 50,000 to 80,000 HHP depending on the job design and customer demand at the wellsites. wellsite. Our equipment has been designed to handle the operating conditions commonly encountered in the Permian Basin and the region’s increasingly high-intensity well completions (including simultaneous hydraulic fracturing ("Simul-Frac"), which involves fracturing multiple wellbores at the same time), which are characterized by longer horizontal wellbores, more stages per lateral and increasing amounts of proppant per well. With the industry transition to lower emissions equipment and Simul-Frac, in addition to several other changes to our customers' job designs, we believe that our available fleet capacity could decline if we decide to reconfigure our fleets to increase active HHP and backup HHP at the wellsites. In Septemberaddition, in 2021 and 2022, we placed an ordercommitted to additional conversions of our Tier II equipment to Tier IV DGB, and to purchase new Tier IV DGB dual-fuel equipment. As such, we entered into conversion and purchase agreements with our equipment manufacturers for 125,000a total of 452,500 HHP of Tier IV DGB dual-fuel equipment and as of December 31, 2023, we have received all of the converted and new Tier IV DGB dual-fuel equipment. In 2022, we entered into three-year electric fleet leases for additional conversions, whicha total of four FORCESM electric-powered hydraulic fracturing fleets with 60,000 HHP per fleet. As of December 31, 2023, we have received 144,000 HHP of FORCESM electric-powered equipment. We currently expect to be delivered at different times throughreceive the remaining equipment associated with the second and third fleets and all equipment associated with the fourth fleet in the first half of 2022.2024.
          In 2019,On November 1, 2022, we entered into a purchase commitmentconsummated the acquisition of all of the outstanding limited liability company interests of Silvertip Completion Services Operating, LLC (the “Silvertip Acquisition”), which provides wireline perforation and ancillary services solely in the Permian Basin in exchange for 108,000 HHP of DuraStim® electric powered hydraulic fracturing equipment. In addition to DuraStim® fleets, we are also evaluating other electric and alternative pressure pumping solutions. In December 2021, we disposed10.1 million shares of our two gas turbines initially purchasedcommon stock valued at $106.7 million, $30.0 million of cash, the payoff of $7.2 million of assumed debt, and the payment of certain other closing and transaction costs. At December 31, 2023, we had 23 wireline units available to provide electrical power to our DuraStim® fleets butwireline perforation and ancillary services. The Silvertip Acquisition positions the Company as determined they were an inefficient power solutiona more resilient and diversified completions-focused oilfield service provider headquartered in the field. In Permian Basin.

On December 1, 2023, we consummated the future, we may lease electrical power equipment from a third party or rely onpurchase of the assets and operations of Par Five Energy Services LLC (“Par Five”), which provides cementing services in the Delaware Basin, in exchange for $25.4 million of cash. Par Five’s business complements our customersexisting cementing business and enables us to provide power solutions for our electric equipment.serve both the Midland and Delaware Basins of the Permian Basin.
Our substantial market presence in the Permian Basin positions us well to capitalize on drilling and completion activity in the region. Primarily, our operational focus has been in the Permian Basin's Midland sub-basin, where our customers have operated. However, we have recently increased our operations in the Delaware sub-basin and are well-positioned to support further increases to our activity in this area in response to demand from our customers. Over time, we expect the Permian Basin's Midland and Delaware sub-basins to continue to command a disproportionate share of future North American E&P spending.
34


          Through our pressure pumping segment (which also includes our cementing operations), we primarily provide hydraulic fracturing services to E&P companies in the Permian Basin. Our hydraulic fracturing fleet has been designed to handle the operating conditions commonly utilized in the Permian Basin and the region's increasingly high-intensity well completions (including Simul-Frac, which involves fracturing multiple wellbores at the same time), which are characterized by longer horizontal wellbores, more stages per lateral and increasing amounts of proppant per well.

          In additionWe have historically conducted our business through four operating segments: hydraulic fracturing, wireline, cementing and coiled tubing. Prior to the fourth quarter of fiscal year 2023, our core pressure pumpingoperating segments met the aggregation criteria and were aggregated into the “Completion Services” reportable segment operations, which includes our cementing operations, we also offer coiled tubing services. Throughand our coiled tubing servicesoperations (which were divested in September 2022) were shown in the “All Other” category.Effective as of the fourth quarter of fiscal year 2023, we revised our segment reporting as we seekdetermined that our three operating segments no longer met the criteria to create operational efficiencies for our customers, which could allow us to capture a greater portion of their capital spending acrossbe aggregated. Our Hydraulic Fracturing and Wireline operating segments meet the lifecyclecriteria of a well.reportable segment. Our cementing and our divested coiled tubing segments are not material, are not separately reportable, and are included within the “All Other” category. Prior period segment information has been revised to conform to our current presentation. For additional financial information on our reportable segments presentation, please see reportable segment information in Part II - Item 8, "Financial Statements and Supplementary Data."

Pioneer Pressure Pumping Acquisition
On December 31, 2018, we consummated the purchase of certain pressure pumping assets and related assets ofreal property from Pioneer Natural Resources USA, Inc. (“Pioneer”) and Pioneer Pumping Services, LLC in the Pioneer Pressure Pumping Acquisition. TheAcquisition in exchange for 16.6 million shares of our common stock and $110.0 million in cash, and concurrently entered into a pressure pumping assets acquired included hydraulic fracturing pumps of 510,000 HHP, four coiled tubing unitsservices agreement (the "Pioneer Services Agreement") with Pioneer.
On March 31, 2022, we entered into an amended and the associated equipment maintenance facility. In connection with the acquisition, we became a long-term service providerrestated pressure pumping services agreement (the “A&R Pressure Pumping Services Agreement”) to Pioneer underreplace the Pioneer Services Agreement providingthat was entered into in connection with the Pioneer Pressure Pumping Acquisition. This agreement expired at the conclusion of its term and was replaced by the Fleet One Agreement and Fleet Two Agreement described below.
On October 31, 2022, we entered into two pressure pumping services agreements (the “Fleet One Agreement” and relatedthe “Fleet Two Agreement”) with Pioneer, pursuant to which we provided hydraulic fracturing services for a term of upwith two committed fleets, subject to 10 years; provided, that Pioneer has the right to terminate the Pioneer Servicescertain termination and release rights. The Fleet One Agreement in whole or part,was effective as of DecemberJanuary 1, 2023 and was terminated on August 31, 2023. The Fleet Two Agreement was effective as of each of the calendar years of 2022, 2024January 1, 2023 and 2026.was terminated on May 12, 2023. In October 2023, Pioneer can increase the number of committed fleets prior to December 31, 2022. Pursuant to the Pioneer Services Agreement, the Company is entitled to receive compensation if Pioneer were to idle committed fleets ("idle fees"); however, we are first required to use all economically reasonable efforts to deploy the idled fleets to another customer. At the present, we have eight fleets committed to Pioneer. During times when there isentered into a significant reduction in overall demand for our services, the idle fees could represent a material portion of our revenues.
          While management believes our relationshipmerger agreement with Pioneer will continue beyond December 31, 2022, if Pioneer elects to terminate the Pioneer Services Agreement effective December 31, 2022, or seeks to renegotiate the terms on which we provide services to Pioneer, it could have a material adverse effect on our future financial condition, results of operations and cash flows.Exxon Mobil Corporation.
Commodity Price and Other Economic Conditions
The oil and gas industry has traditionally been volatile and is influencedcharacterized by a combination of long-term, short-term and cyclical trends, including domestic and international supply and demand for oil and gas, current and expected future prices for oil and gas and the perceived stability and sustainability of those prices, and capital investments of E&P companies toward their development and production of oil and gas reserves. The oil and gas industry is also impacted by general domestic and international economic conditions such as supply chain disruptions and inflation, war and political instability in oil producing countries, government regulations (both in the United States and internationally), levels of consumer demand, adverse weather conditions, and other factors that are beyond our control.
Since October 2023, an ongoing conflict between Israel and Palestinian militants in the Israel-Gaza region has led to significant armed hostilities. The global public health crisisgeopolitical and macroeconomic consequences of this conflict remain uncertain, and such events, or any further hostilities in the Israel-Gaza region or elsewhere, could severely impact the world economy, the demand for and price of crude oil and the oil and gas industry generally and may adversely affect our financial condition.
Similarly, the geopolitical and macroeconomic consequences of the Russian invasion of Ukraine, including the associated withsanctions, and the adverse impacts of the COVID-19 pandemic could continuein recent years have resulted in volatility in supply and demand dynamics for crude oil and associated volatility in crude oil pricing. As the global response to have an adverse effect on global economic activitythe COVID-19 pandemic began to wane, the demand and prices for crude oil increased from the foreseeable future. Somelows experienced in 2020, with the WTI average crude oil price
35


reaching approximately $94 per barrel in 2022, the highest average price in the prior nine years. However, in 2023, the WTI average crude oil price declined to approximately $78 per barrel. We believe that the volatility of the challengescrude oil prices in recent years has been partly driven by declines in crude oil supplies, concerns over sanctions resulting from Russia's invasion of Ukraine, concerns over a potential disruption of Middle Eastern oil supplies resulting from the COVID-19 pandemic that have impacted our business include restrictions on movement of personnelongoing conflict between Israel and associated gatherings, shortage of skilled labor, cost inflation and supply chain disruptions. Additionally, with most of the large, capitalized E&P companiesPalestinian militants in the United States, including our customers, closely managing their operating budget and exercising capital discipline, we do not currently expect significant increases inIsrael-Gaza region, slower crude oil production overgrowth due to the short-to-medium term. Furthermore,lack of reinvestment in the oil and gas industry in the last two years, recent OPEC+ has indicated that they will continue with their plans to manage production levels by gradually increasingcuts of approximately 1.3 million barrels per day and concerns of a potential global recession resulting from high inflation and interest rates.
With the significant increase in global crude oil output. Withprices from 2021, including the tightness inWTI crude oil production and growing demand for crude oil,price, there has beenwas a significant increase in rig count and WTI crude oil prices have increased to over $90 per barrel in February 2022 from its recent lowest point of $20 per barrel in March 2020. Thethe Permian Basin rig count has increased significantly from approximately 179 at the beginning of 2021 to approximately 294353 at the end of 2021,2022, according to the Baker Hughes. AlthoughHughes Company (“Baker Hughes”). Following the increase in rig count and the WTI crude oil price, the oilfield service industry has experienced increased demand for its completion services, and improved pricing. However, we have recently experienced a 13% decrease in the rig count in 2023 to 309 at the end of 2023 which resulted in a reduction in the demand for completion services and pressure on pricing of our services.
Sustained levels of high inflation have likewise caused the U.S. Federal Reserve and other central banks to increase interest rates, and to the extent elevated inflation remains, we may experience further cost increases for our operations, including interest rates, labor costs and equipment. We cannot predict any future trends in the rate of inflation and crude oil prices. A significant increase in or continued high levels of inflation, to the extent we are unable to timely pass-through the cost increases to our customers, or further declines in crude oil prices are currentlywould negatively impact our business, financial condition and results of operations. See Part II, Item 1A. "Risk Factors—We may be adversely affected by the effects of inflation."
35


at a 7-year high, the oilfield services industry, including the pressure pumping segment, has not fully recovered as evidenced by continued depressed pricing for most of our services, and shortages of skilled labor force in the Permian Basin, coupled with rising inflationary costs. However, we still believe that the Permian Basin, our primary area of operation, will be the most attractive basin to E&P companies and should command higher prices and associated profitability, if the overall demand for crude oil and our services continues to increase.
Government regulations and investors are demanding the oil and gas industry transition to a lower emissions operating environment, including the upstream and oilfield servicesservice companies. As a result, we are working with our customers and equipment manufacturers to transition our equipment to a lower emissions profile. Currently, a number of lower emission solutions for pumping equipment, including Tier IV DGB dual-fuel, FORCESM electric, direct drive gas turbine and other technologies have been developed, and we expect additional lower emission solutions will be developed in the future. We are continually evaluating these technologies and other investment and acquisition opportunities that would support our existing and new customer relationships. The transition to lower emissions equipment is quickly evolving and will be capital intensive. Over time, we may be required to convert substantially all of our conventional Tier II equipment to lower emissions equipment. IfWe have transitioned our hydraulic fracturing available equipment portfolio from approximately 10% lower emissions equipment in 2021 to approximately 35% in 2022 and 60% in 2023, and expect to increase to approximately 65% by the end of the first half of 2024. To the extent any of our customers have certain expectations or requirements with respect to emissions reductions from their contractors, if we are unable to continue quickly transitiontransitioning to lower emissions equipment, and meet our and our customers’ emissions goals, the demand for our services could be adversely impacted.
          TheIf the Permian Basin rig count increase, WTI crude oil price increase and cost inflation could be indicative of an energy market recovery. If the rig count and market conditions continue to improve, including improved customers' pricing for our services and labor availability, and we are able to meet our customers' lower emissions equipment demands, we believe our operational and financial results will also continue to improve. However, ifIf the rig count or market conditions do not improve or decline in the future, and we are unable to increase our pricing or pass-through future cost increases to our customers, there could be a material adverse impact on our business, results of operations and cash flows.flows.
Our results of operations have historically reflected seasonal tendencies, typically in the fourth quarter, relating to the holiday season, inclement winter weather and exhaustion of our customers' annual budgets. As a result, we typically experience declines in our operating and financial results in November and December, even in a stable commodity price and operations environment.

Actions to AddressIn connection with the Economic Impactreview of COVID-19
          Since March 2020,our power ends estimated useful life, effective January 1, 2023, we initiated several actions to mitigateare writing off the anticipated adverse economic conditionsremaining book value of power ends that prematurely fail as accelerated depreciation. These write-off amounts were $12.5 million, $11.8 million, $8.4 million and $6.0 million for the immediate futurethree months ended March, 31, 2023, June 30, 2023, September 30, 2023 and December 31, 2023, respectively. However, to support our financial position, liquidity and the efficient continuity of our operations as follows:
Growth Capital: our operations were driven by more dedicated work from our customers. Our capital expenditure program was focused on maintaining existing dedicated demand for our equipment. We reduced capital investment in speculative growth.
Other Expenditures: we strategically managed our maintenance program in line with our projected activity levels. We continuedconform to seek lower pricing and cost saving measures for our expendable items, materials used in day-to-day operations and large component replacement parts. In addition, with the supply chain disruptions, we worked closely with our vendors to better plan our future needs and accelerated purchases of certain components and spare parts;
Labor Force: we implemented several strategies including pay adjustments of approximately 8% to retain and attract skilled workforce that will support our operations;

Our Assets and Operations
          ThroughCompletion services includes our pressure pumping segment, which includeshydraulic fracturing, wireline and cementing operations, weoperations. We primarily provide hydraulic fracturingthese services to E&P companiescompanies in the Permian Basin. OurDuring the year ended December 31, 2023, our hydraulic fracturing, fleets havewireline and cementing operations accounted for 78.5%, 14.1% and 7.4% of our total revenue, respectively. Our equipment has been designed to handle Permian Basin specific operating conditions and the region’s increasingly high‑intensity well completions, which are characterized by longer horizontal wellbores, more frac stages per lateral and increasing amounts of proppant per well. We plan to continually reinvest in our equipment to ensure optimal performance and reliability.
          In addition to our core pressure pumping segment operations, we also offer a suite of complementary well completion and production services, including coiled tubing and other services. We believe these complementary services create operational efficiencies for our customers and could allow us to capture a greater portion of their capital spending across the lifecycle of a well in the future.
37


How We Generate Revenue
We generate revenue primarily through our pressure pumping segment,completion services, and more specifically, by providing hydraulic fracturing services to our customers. We own and operate a fleet of mobile hydraulic fracturing, wireline and cementing units and other auxiliary equipment to perform fracturing services.completion services to E&P companies. We also provide personnel and services that are tailored to meet each of our customers’ needs.
Hydraulic fracturing operations account for a significant portion of our total revenue. We charge our customers on a per‑job basis, in which we set pricing terms after receiving full specifications for the requested job, including the lateral length of the customer’s wellbore, the number of frac stages per well, the amount of proppant and chemicals to be used and other parameters of the job. We also could generate revenue from idle fees from our customers in certain circumstances when committed fleets are idled.
In addition to hydraulic fracturing services, we generate revenue through the complementaryother completion services that we provide to our customers, including cementing, coiled tubingwireline and other related services. These completion services are complementary servicesto each other and are undertaken in unison with hydraulic fracturing services. They are provided through various contractual arrangements, including on a turnkey contract basis, in which we set a price to perform a particular job, or a daywork contract basis, in which we are paid a set price per day for our services. We are also sometimes paid by the hour for these complementary services.
Demand for our services is largely dependent on oil and natural gas prices, and our customers’ well completion budgets and rig count. Our revenue, profitability and cash flows are highly dependent upon prevailing crude oil prices and expectations about future prices. For many years, oil prices and markets have been extremely volatile. Prices are affected by many factors beyond our control. The average WTI oil pricesprice per barrel werewas approximately $78$68, $39, $94 and $57$68 for the years ended December 31, 2021, 20202023, 2022 and 2019,2021, respectively. In February 2022,January 2024, the WTIWTI oil price was overapproximately $74 p $90 perer barrel. If the WTI oil price declines in the future or remains highly volatile, demand for our services may be negatively impacted, which could result in a significant decrease in our future profitability and cash flows. We monitor the oil and natural gas prices and the Permian Basin rig count to enable us to more effectively plan our business and forecast the demand for our services.

Costs of Conducting our Business
The principal direct costs involved in operating our business are direct labor, expendables and other direct costs.
Direct Labor Costs. Payroll and benefit expenses related to our crews and other employees that are directly or indirectly attributable to the effective delivery of services are included in our operating costs. Direct labor costs amounted to 22.4%28.7% and 22.7%27.7% of total costs of service for the years ended December 31, 20212023 and 2020,2022, respectively. The increase in our direct labor costs percentage is driven by wage adjustments and higher headcount resulting from business acquisitions.
Expendables. Expendables include the product and freight costs associated with proppant, chemicals and other consumables used in our pressure pumpingcompletion services and other operations. These costs comprise a substantial variable component of our service costs, particularly with respect to the quantity and quality of sand and chemicals demanded when providing hydraulic fracturing services. Expendable productproduct costs comprised approximately 41.8%,32.9% and 37.6%33.6% of total costs of service for the years ended December 31, 20212023 and 2020,2022, respectively. The percentage increasedecrease in our expendable product costexpendables in 20212023 was primarily attributable to certain customers electing to directly source sand and the increase in our activity levels and higher freight cost.associated logistics.
Other Direct Costs. We incur other direct expenses related to our service offerings, including the costs of fuel, repairs and maintenance, general supplies, equipment rental and other miscellaneous operating expenses. Fuel is consumed both in the operation and movement of our hydraulic fracturing fleet and other equipment. Repairs and maintenance costs are expenses directly related to upkeep of equipment, which have been amplified by the demand for higher horsepower jobs. Capital expenditures to upgrade or extend the useful life of equipment are capitalized and are not included in other direct costs. Other direct costs were 35.8% 38.4% and 39.7%38.7% of total costs of service for the years ended December 31, 20212023 and 2020,2022, respectively. The percentage decrease in 2021 was primarily driven by most of our customers directly sourcing diesel and pricing improvement.

How We Evaluate Our Operations
Our management uses Adjusted EBITDA or Adjusted EBITDA margin to evaluate and analyze the performance of our various operating segments.
Adjusted EBITDA and Adjusted EBITDA Margin
We view Adjusted EBITDA and Adjusted EBITDA margin as important indicators of performance. We define EBITDA as our earnings, before (i) interest expense, (ii) income taxes and (iii) depreciation and amortization. We define Adjusted EBITDA as EBITDA, plus (i) loss/(gain) on disposal of assets, (ii) stock-based compensation, (iii) other expense/(income) and (iii)(iv) other unusual or nonrecurring (income)/expenses, such as impairment charges, retention bonuses, severance, costs related to asset acquisitions, insurance recoveries, costs related to SEC investigation and class action lawsuits and one-time professional fees and advisory fees.legal settlements. Adjusted EBITDA margin reflects our Adjusted EBITDA as a percentage of our revenues.
39


Adjusted EBITDA and Adjusted EBITDA margin are supplemental measures utilized by our management and other users of our financial statements such as investors, commercial banks, and research analysts, to assess our financial performance because it allows us and other users to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense), asset base (such as depreciation and amortization), nonrecurring (income) expenses and items outside the control of our management team (such as income taxes). Adjusted EBITDA and Adjusted EBITDA margin have limitations as analytical tools and should not be considered as an alternative to net income (loss), operating income (loss), cash flow from operating activities or any other measure of financial performance presented in accordance with generally accepted accounting principles in the United States of America ("GAAP").GAAP.
Note Regarding Non‑GAAP Financial Measures
Adjusted EBITDA and Adjusted EBITDA margin are not financial measures presented in accordance with GAAP ("non-GAAP"), except when specifically required to be disclosed by GAAP in the financial statements. We believe that the presentation of Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors in assessing our financial condition and results of operations because it allows them to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure, asset base, nonrecurring expenses (income) expenses and items outside the control of the Company. Net income (loss) is the GAAP measure most directly comparable to Adjusted EBITDA. Adjusted EBITDA and Adjusted EBITDA margin should not be considered as alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important limitations as analytical tools because they exclude some, but not all, items that affect the most directly comparable GAAP financial measures. You should not consider Adjusted EBITDA and Adjusted EBITDA margin in isolation or as a substitute for an analysis of our results as reported under GAAP. Because Adjusted EBITDA and Adjusted EBITDA margin may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Hydraulic Fracturing. Our hydraulic fracturing segment revenues increased 12.0%, or $137.3 million for the year ended December 31, 2023, as compared to the year ended December 31, 2020.2022. The increases wereincrease was primarily attributable to the significant increase in demand for pressure pumping services, following the rebound from the depressed oil prices and slowdown in economic activity resulting from the COVID-19 pandemic. The increase in demand for our pressure pumping services resulted in an approximate 20% increase in our averageexisting and new customers' activity levels, resulting in higher demand for completion services, and improved pricing. Our effectively utilized hydraulic fracturing fleet count was flat at 15 active fleets for the year ended December 31, 2023, as in the year ended December 31, 2022. The effectively utilized fleet count to approximately 12is determined by dividing the total number of days our fleets were actively working at wellsites during the month by 25 days (predetermined number of expected active fleetswork days in 2021 from 10 active fleets in 2020. Included in ourthe month). Our revenue for the years ended December 31, 20212023 and 2020 was revenue generated from idleDecember 31, 2022 included reservation fees charged to a certain customer of approximately $9.5 million $0 and $47.2$27.0 million, respectively.

The increase in revenues from services other than pressure pumping duringwas primarily attributable to a full year of activity for the year ended December 31, 2021,2023 compared to only 61 days of activity during year ended December 31, 2022 since the wireline business was acquired on November 1, 2022.
All Other. Revenue from the All Other category comprising of our cementing and our disposed of coiled tubing operations increased 14.2%, or $15.0 million for the year ended December 31, 2023, as compared to the year ended December 31, 2022. The increase was primarily attributable to the increase in utilization experiencedour existing and new customers' activity levels, resulting in higher demand for completion services, and improved pricing, partially offset by the discontinuation of our coiled tubing operations which was driven by increased E&P completions activity following the rebound from the depressed oil prices and impact of the COVID-19 pandemic.effective September 1, 2022.
Cost of Services.  Cost of services increased 13.3%28.2%, or $78.0$249.0 million, to $662.3$1,131.8 million for the year ended December 31, 2021,2023, from $584.3$882.8 million during the year ended December 31, 2022. Cost of services by reportable segment was as follows:

Changes to our operational activity levels and our customers’ credit ratings have an impact on our total eligible accounts receivable, which could result in significant changes to our borrowing baseBorrowing Base and, therefore, our availability under our ABL Credit Facility. We believe our remaining monthly availability under our ABL Credit Facility will be adversely impacted if oil and gas market conditions decline in the future.
We received advance payments from a customer for our services, and the amount outstanding in connection with the advance payments was $19.2 million and $10.0 million as of December 31, 2023 and 2022, respectively. These amounts included restricted cash of $0 and $10.0 millionas of December 31, 2023 and 2022, respectively.

On May 17, 2023, the Board authorized and the Company announced a share repurchase program that allows the Company to repurchase up to $100 million of the Company's common stock beginning immediately and continuing through and including May 31, 2024. The shares may be repurchased from time to time in open market transactions, block trades, accelerated share repurchases, privately negotiated transactions, derivative transactions or otherwise, certain of which may be made pursuant to a trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act, as amended, in compliance with applicable state and federal securities laws. The timing, as well as the number and value of shares repurchased under the program, will be determined by the Company at its discretion and will depend on a variety of factors, including management's assessment of the intrinsic value of the Company's common stock, the market price of the Company's common stock, general market and economic conditions, available liquidity, compliance with the Company's debt and other agreements, applicable legal requirements, and other considerations. The Company is not obligated to purchase any shares under the repurchase program, and the program may be suspended, modified, or discontinued at any time without prior notice. The Company expects to fund the repurchases using cash on hand and expected free cash flow to be generated through May 2024. During the year ended December 31, 2023, the Company repurchased and retired 5.8 million shares of common stock for an aggregate of $51.7 million, an average price per share of $8.93 including commissions, under the repurchase program. As of February 18, 2022, we had no borrowingsDecember 31, 2023, $48.3 million remained authorized for future repurchases of common stock under our ABL Credit Facility and our total liquidity was approximately $151.3 million, consisting of cash and cash equivalents of $76.0 million and $75.3 million of availability under our ABL Credit Facility.the repurchase program.

Capital Requirements, Future Sources and Use of Cash
Capital expenditures incurred were $165.2$310.0 million during the year ended December 31, 2023, as compared to $365.3 million during the year ended December 31, 2021, as compared to $81.2 million during the year ended December 31, 2020. During the year ended December 31, 2020, we reduced our capital expenditures following the depressed demand for our pressure pumping services as a result of the COVID-19 pandemic and depressed energy market.2022. The significant portion of our total capital expenditures incurred during the year ended December 31, 2023 were comprised of maintenance capital expenditures.expenditures and conversion of our hydraulic fracturing equipment to lower emissions equipment.
Our future material use of cash will be to fund our capital expenditures. Capital expenditures for 20222024 are projected to be primarily related to maintenance capital expenditures to supportextend the useful life of our existing pressure pumpingcompletion services assets, costs to convert some existing equipment to lower emissions pressure pumping equipment, strategic purchases and other ancillary equipment purchases, subject to market conditions and customer demand. Our future capital expenditures depend on our projected operational activity, emission requirements and planned conversions to lower emissions equipment, among other factors, which could vary significantly throughout the year. Based on our current plan and projected activity levels for 2022,2024, we expect our capital expenditures to range between $250.0$200 million to $300.0$250 million. We could incur significant additional capital expenditures if our projected activity levels increase during the course of the year, inflation and supply chain tightness continues to adversely impact on our operations or we invest in new or different lower emissions equipment. The Company will continue to evaluate the emissions profile of its fleetequipment over the coming years and may, depending on market conditions, convert or retire additional conventional Tier II equipment in favor of lower emissions equipment. The Company’s decisions regarding the retirement or conversion of equipment or the addition of lower emissions equipment will be subject to a number of factors, including (among other factors)
the availability of equipment, including parts and major components, supply chain disruptions, prevailing and expected commodity prices, customer demand and requirements and the Company’s evaluation of projected returns on conversion or other capital expenditures. Depending on the impacts of these factors, the Company may decide to retain conventional equipment for a longer period of time or accelerate the retirement, replacement or conversion of that equipment.
In addition, we have option agreements with our equipment manufacturer to purchase an additional 108,000 HHP of DuraStim® hydraulic fracturing equipment through July 31, 2022.
We anticipate our capital expenditures will be funded by existing cash, cash flows from operations, and if needed, borrowings under our ABL Credit Facility. Our cash flows from operations will be generated from services we provide to our customers and idle fees if a customer (Pioneer) decides to idle committed fleets and we are not able to deploy the idled fleets to another customer. During times when there is a significant reduction in overall demand for our services, the idle fees could represent a material portion of our revenues and cash flows from operations.customers.

(1)AsExclusive of December 31, 2021, we had no borrowings under our ABL Credit Facility. If we decide to borrow fromfuture commitment fees, amortization of deferred financing costs, interest expense or other fees on our ABL Credit Facility inbecause obligations thereunder are floating rate instruments and we cannot determine with accuracy the timing of future loan advances, repayments of future interest expenserates to be changed. However, assuming a weighted average interest rate of 6.69%, and that our ABL Credit Facility debt balance remains the same, our estimated annual interest payment will be charged based on the agreed contractual interest rates. However, we are obligated to pay agency and commitment fees on unused balance which could be up to approximately $1.2 million annually, depending on our utilization of the ABL Credit Facility.$3.0 million.
(2)Operating leases exclude short-term leases and other commitments (see Note 14.17. Leases and Note 15.18. Commitments and Contingencies in the financial statements for additional disclosures).
(3)Includes our leases for FORCESM electric-powered hydraulic fracturing fleets (240,000 HHP). We expect to receive the remaining equipment under these leases in the first half of 2024.
(4)Finance lease for certain power generation equipment (70 MW) to support electric-powered hydraulic fracturing equipment.

(5)Relates to a take-or-pay sand commitment with one of our sand vendors.

(6)Represents the unpaid portion of the purchase consideration on our acquisition of Par Five assets to be used to cover the amount by which the estimated purchase price exceeds the final purchase price, if any.

We enter into other purchase agreements with Sand suppliersSuppliers to secure supply of sand in the normal course of our business. The agreements with the Sand suppliersSuppliers require that we purchase minimum volume of sand, based primarily on a certain percentage of our sand requirements from our customers or in certain situations based on predetermined fixed minimum volumes, otherwise certain penalties (shortfall fees) may be charged. The shortfall fee represents liquidated damages and is either a fixed percentage of the purchase price for the minimum volumes or a fixed price per ton of unpurchased volumes. Our current agreements with Sand suppliersSuppliers expire at different times prior to December 31, 2025.2025. Our agreed upon sand requirements or minimum volumes are based on certain future events such as our customer demand, which cannot be reasonably estimated. If the activity level of our customers declines and the future demand for our services is materially and adversely affected, we may be required to pay for more sand from one of our Sand suppliersSuppliers than we need in the performance of our services, regardless of whether we take physical delivery of such sand. In such an event, we may be required to pay shortfall fees or other penalties under the purchase agreement, which could have a material adverse effect on our business, financial condition, or results of operations.
Recent Accounting Pronouncements
Disclosure concerning recently issued accounting standards is incorporated by reference to "Note 2- Significant Accounting Policies" of our Consolidated Financial Statements contained in this Annual Report.
Critical Accounting Policies and Estimates
44


The discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally acceptable in the United States of America.GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported revenues and expenses during the years. We evaluate these estimates and assumptions on an ongoing basis and base our estimates on historical experience, current conditions and various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Our actual results may materially differ from these estimates.
Listed below are the accounting policies that we believe are critical to our financial statements due to the degree of uncertainty regarding the estimates or assumptions involved, and that we believe are critical to the understanding of our operations.
Property and Equipment
Our property and equipment are recorded at cost, less accumulated depreciation.
Upon sale or retirement of property and equipment, the cost and related accumulated depreciation are removed from the balance sheet and the net amount, less proceeds from disposal, is recognized as a gain or loss in earnings.
We primarily retiredretire certain components of equipment such as fluid ends and power ends, rather than the entire pieces of equipment, and theequipment. The associated loss is recorded in our statement of operations as part of net loss on disposal of assets, which was $64.6$73.0 million $58.1, $102.1 million and $106.8$64.6 million for the years ended December 31, 2021, 20202023, 2022 and 2019,2021, respectively.
45


The estimated useful lives and salvage values of property and equipment is subject to key assumptions such as maintenance, utilization and job variation. Unanticipated future changes in these assumptions could negatively or positively impact our net income (loss). A 10% change in the useful lives of our property and equipment would have resulted in approximately $13.3$17.0 million impact on pre-tax loss during the year ended December 31, 2021.2023. Depreciation of property and equipment is provided on the straight‑line method over estimated useful lives as shown in the table below.

Impairment of Long-Lived Assets
In accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 360 regarding Accounting for the Impairment or Disposal of Long‑Lived Assets, we review the long‑lived assets including intangible assets to be held and used whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future undiscounted cash flows attributable to the assets is less than the carrying amount of such assets. In this circumstance, we recognize an impairment loss for the amount by which the carrying amount of the assets exceeds the estimated fair value of the asset. Our cash flow forecasts require us to make certain judgments regarding long‑term forecasts of future revenue and costs and cash flows related to the assets subject to review. The significant assumption in our cash flow forecasts is our estimated equipment utilization and profitability. The significant assumption is uncertain in that it is driven by future demand for our services and utilization, which could be impacted by crude oil market prices, future market conditions and technological advancements. Our fair value estimates for certain long‑lived assets require us to use significant other observable inputs, including assumptions related to market based on recent auction sales or selling prices of comparable equipment. The estimates of fair value are also subject to significant variability, are sensitive to changes in market conditions, and are reasonably likely to change in the future.
If the crude oil market declines or the demand for our services does not recover, and if our equipment remains idle or under‑utilized,underutilized, the estimated fair value of such equipment may decline, which could result in future impairment charges. Though the impacts of variations in any of these factors can have compounding or off‑settingoffsetting impacts, a 10% decline in the estimated future cash flows of our existing asset groups will not indicate an impairment.
          Our DuraStim® equipment is yet to be commercialized. IfIn 2022, we are not able to successfully commercialize the DuraStim® equipment, and are not able to deploy the equipment for alternative uses, we will incurrecorded impairment lossesexpense of $57.5 million on the carrying value of the DuraStim® equipment. As of December 31, 2021, the carrying value of our DuraStim® electric-powered hydraulic fracturing equipment is approximately $90 million.within the hydraulic fracturing operating segment.
Goodwill
45


Goodwill and Other Intangible Assets
Goodwill is the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets and liabilities recognized. Goodwill is not amortized. We perform an annual impairment test of goodwill and intangible assets as of December 31, or more frequently if circumstances indicate that impairment may exist.
          There were no additions to, or disposalIn connection with the Silvertip Acquisition, we added $23.6 million of goodwill during the year ended December 31, 2021.2022. There were no additions to goodwill during the year ended December 31, 2023. The wireline operating segment is the only segment with goodwill at December 31, 2023 and 2022. There were no goodwill impairment losses during the years ended December 31, 2023 and 2022. We performed our annual goodwill impairment test in accordance with ASC 350, Intangibles—Goodwill and Other, on December 31, 2023, at which time, we determined that the fair value of our wireline reporting unit was substantially in excess of its carrying value. The quantitative impairment test we perform for goodwill utilizes certain assumptions, including forecasted active fleet revenueequipment utilization, pricing and cost assumptions. Our discounted cash flow analysis includes significant assumptions regarding discount rates, fleet utilization, expected profitability margin, forecasted maintenance capital expenditures, the timing of an anticipated market recovery, and the timing of expected cash flow. As such, our goodwill analysis incorporates inherent uncertainties that are difficult to predict in volatile economic environments and could result in impairment charges in future periods if actual results materially differ from the estimated assumptions utilized in our forecast. As of December 31, 2023 and 2022, our goodwill carrying value was $23.6 million and $23.6 million, respectively.
Intangible assets consist of customer relationships and trademark/trade name. In March 2020, crude oil prices declined significantly, an indication that a triggering event has occurred,connection with the Silvertip Acquisition, we added intangible assets consisting of $46.5 million of customer relationships and as such, we recorded in our pressure pumping reportable segment, goodwill impairment expense$10.8 million of $9.4 million
46


trademark/trade name during the year ended December 31, 2020. There was2022. Intangible assets are amortized on a straight‑line basis with an estimated useful life of ten years. Our estimated useful life could be sensitive to changes in market conditions and management’s judgment, and are likely to change in the future if certain events occur. Presently, there are no carrying valueevents or circumstances that will cause us to believe that our estimated useful life for goodwill in our balance sheet as of December 31, 2021 because our goodwill carrying value was fully written off during 2020.intangible assets are likely to change.
Income Taxes
Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of differences between the consolidated financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, and the results of recent operations. If we determine that we would not be able to fully realize our deferred tax assets in the future in excess of their net recorded amount, we would record a valuation allowance, which would increase our provision for income taxes. In determining our need for a valuation allowance as of December 31, 2021,2023, we have considered and made judgments and estimates regarding estimated future taxable income. These estimates and judgments include some degree of uncertainty and changes in these estimates and assumptions could require us to record additional valuation allowances for our deferred tax assets and the ultimate realization of tax assets depends on the generation of sufficient taxable income.
Our methodology for recording income taxes requires a significant amount of judgment in the use of assumptions and estimates. Additionally, we forecast certain tax elements, such as future taxable income, as well as evaluate the feasibility of implementing tax planning strategies. Given the inherent uncertainty involved with the use of such variables, there can be significant variation between anticipated and actual results. Unforeseen events may significantly impact these variables, and changes to these variables could have a material impact on our income tax accounts. The final determination of our income tax liabilities involves the interpretation of local tax laws and related authorities in each jurisdiction. Changes in the operating environments, including changes in tax law, could impact the determination of our income tax liabilities for a tax year.
Share Repurchases
All shares of common stock repurchased through the Company's share repurchase program are retired upon repurchase. The Company accounts for the purchase price of repurchased common stock in excess of par value ($0.001 per share of common stock) as a reduction of additional paid-in capital, and will continue to do so until additional paid-in capital is reduced to zero. Thereafter, any excess purchase price will be recorded as a reduction of retained earnings.

Item 7A. Quantitative and Qualitative Disclosure of Market Risks
Foreign Currency Exchange Risk
Our operations are currently conducted entirely within the U.S;U.S.; therefore, we had no significant exposure to foreign currency exchange risk in 2021.2023.
Commodity Price Risk
Our materialmaterials and fuel purchases expose us to commodity price risk. Our material costs primarily include the cost of inventory consumed while performing our pressure pumpingcompletion services such as proppants, perforating guns, chemicals, guar, trucking and fluid supplies. Our fuel costs consist primarily of diesel and natural gas used by our various trucks and other motorized equipment. The prices for fuel and materials in our inventory are volatile and are impacted by changes in supply and demand, as well as market uncertainty and regional shortages. Historically, we have generally been able to pass along a significant portion of our commodity price risk to our customers; however, we may be unable to do so in the future. We do not engage in commodity price hedging activities.
Interest Rate Risk
We may be subject to interest rate risk on variable rate borrowings under our ABL Credit Facility. We do not currently engage in interest rate derivatives to hedge our interest rate risk. The impact of a 1% increase in interest rates on our variable rate debt would have resulted in an increase in interest expense and corresponding decrease/(increase)/decrease in pre‑tax income/(loss)/income of approximately $0.5 million, $0, $0.40.1 million and $1.3 million$0, for the years ended December 31, 2021, 20202023, 2022 and 2019,2021, respectively.
Credit Risk
Financial instruments that potentially subject us to concentrations of credit risk are trade receivables. We extend credit to customers and other parties in the normal course of business. We have established various procedures to manage our credit exposure, including maintaining an allowance for doubtful accounts.

Acquisition — Par Five Energy Services, LLC — Fair value of assets acquired, and liabilities assumed — Refer to Notes 1 and 4 to the financial statements
Critical Audit Matter Description
The Company completed the acquisition of Par Five Energy Services, LLC (“Par Five”) for a total purchase consideration of $25.4 million on December 1, 2023 (the “Acquisition”). The Company accounted for the Acquisition using the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated to the assets acquired and
48


liabilities assumed based on their respective estimated fair values. The largest asset classes acquired include property and equipment consisting mainly of oilfield cementing pumps, vehicles, trailer, tanks, and support equipment. The method for determining fair value varied depending on the type of the asset or liability and involved management making significant estimates related to assumptions such as replacement cost, normal useful life and economic obsolescence.
We identified the valuation of property and equipment arising out of the Acquisition as a critical audit matter because of the estimates and assumptions management makes to determine the fair value of these assets. This required a high degree of auditor judgement and an increased extent of effort, including the need to involve our internal valuation specialists, when performing audit procedures to evaluate the reasonableness of management’s assumptions such as replacement cost, normal useful life and economic obsolescence.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the fair value of property and equipment acquired as part of the Acquisition included the following, among others:
We obtained an understanding of the relevant controls related to the recording of assets acquired and liabilities assumed in a business combination and tested such controls for design and operating effectiveness.
With the assistance of our internal valuation specialists, we evaluated the reasonableness of the valuation methodology and significant assumptions including estimates of trend factor calculation, replacement cost, normal useful life, and economic obsolescence by (1) evaluating the source information and assumptions used by management, (2) testing the mathematical accuracy of the calculation, and (3) comparing our estimates to those used by management.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors of ProPetro Holding Corp. and Subsidiaries:

Opinion on Internal Control over Financial Reporting
We have audited ProPetro Holding Corp and Subsidiaries (the Company’s) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements of the Company as of and for the year ended December 31, 2023 and our report dated March 13, 2024 expressed an unqualified opinion on the Company'sthose consolidated financial statements.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting.reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment.
The Company did not maintain adequate segregation of duties or sufficient compensating management review controls to effectively mitigate an inadequate system access control configuration in its accounting system in which manual journal entry approvers can modify the entries before posting. This deficiency is solely related to manual journal entries and has no impact on system-generated journal entries flowing through its accounting system and other feeder systems. This issue impacts all manual journal entries impacting all affected transaction cycles. Due to this control deficiency, other manual-dependent controls were deemed ineffective.
This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2023 consolidated financial statements, and this report does not affect our report dated March 13, 2024, on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the
50


company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

On December 31, 2018, we consummated the purchase of certain pressure pumping assets and related assets ofreal property from Pioneer Natural Resources USA, Inc. ("Pioneer"(“Pioneer”) and Pioneer Pumping Services, LLC (the "Pioneer Pressure(“Pioneer Pumping Acquisition"Services”). The in connection with our purchase of certain pressure pumping assets acquired were used to provide integrated well completion servicesand real property (the “Pioneer Pressure Pumping Acquisition”) in the Permian Basin to Pioneer’s completion and production operations. The acquisition cost of the assets was comprised of $110.0 million of cash andexchange for 16.6 million shares of our common stock.stock and $110.0 million in cash, and concurrently entered into a pressure pumping services agreement (the "Pioneer Services Agreement") with Pioneer. The pressure pumping assets acquired included hydraulic fracturing pumps of 510,000 hydraulic horsepower ("HHP"), 4four coiled tubing units and the associated equipment maintenance facility. In connection with the acquisition,
On March 31, 2022, we became a long-term service provider to Pioneer under aentered into an amended and restated pressure pumping services agreement (the "Pioneer“A&R Pressure Pumping Services Agreement"Agreement”), providing pressure pumping and related services for a term of up to 10 years; provided, that Pioneer has the right to terminatereplace the Pioneer Services Agreement that was entered into in whole or in part,connection with the Pioneer Pressure Pumping Acquisition. This agreement expired at the conclusion of its term and was replaced by the Fleet One Agreement and Fleet Two Agreement described below.
On October 31, 2022, we entered into two pressure pumping services agreements (the “Fleet One Agreement” and the “Fleet Two Agreement”) with Pioneer, pursuant to which we provided hydraulic fracturing services with two committed fleets, subject to certain termination and release rights. The Fleet One Agreement was effective as of DecemberJanuary 1, 2023 and was terminated on August 31, 2023. The Fleet Two Agreement was effective as of each of the calendar years of 2022, 2024January 1, 2023 and 2026.was terminated on May 12, 2023.

At the present, we have 8 fleets committed to Pioneer.entered into a merger agreement with Exxon Mobil Corporation.
2. SIGNIFICANT ACCOUNTING POLICIES
A summary of the significant accounting policies consistently applied in the preparation of the accompanying consolidated financial statements are as follows:
Principles of Consolidation — The accompanying consolidated financial statements include the accounts of Holding and its wholly owned subsidiary, Services.subsidiaries, Services and Silvertip. All intercompany accounts and transactions have been eliminated in consolidation.
Basis of Presentation — The accompanying consolidated financial statements and related notes have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission ("SEC") and in conformity with accounting principles generally accepted in the United States of America ("GAAP").
Use of Estimates — Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the reporting period. Such estimates include, but are not limited to, allowance for credit losses, useful lives for depreciation of property and equipment, estimates of fair value of property and equipment, estimates related to fair value of reporting units for purposes of assessing goodwill, (if any),intangible assets, discount rates underlying our lease right-of-use assets and

liabilities, estimates related to deferred tax assets and liabilities, including any related valuation allowances, and estimates of fair value of stock‑based compensation. Actual results could differ from those estimates.
Revenue Recognition — The Company’s services are sold based upon contracts with customers. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. The following
Hydraulic fracturing is a descriptionan oil well completion technique, which is part of the principal activities, aggregated into our 1 reportable segment—"Pressure Pumping" and "all other" category, from which the Company generates its revenue.
Pressure Pumping — Pressure pumping consists of downhole pumping services, which includes hydraulic fracturing (inclusive of acidizing services) and cementing.
Hydraulic fracturingoverall well completions process. It is a well-stimulation technique intended to optimize hydrocarbon flow paths during the completion phase of shale wellbores.wellbores. The process involves the injection of water, sand and chemicals under high pressure into shale formations. Our hydraulic fracturing contracts with our customers have one

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)
performance obligation, which is the contracted total stages, satisfied over time. We recognize revenue over time using a progress output, unit-of-work performed method, which is based on the agreed fixed transaction price and actual stages completed. We believe that recognizing revenue based on actual stages completed faithfully depicts how our hydraulic fracturing services are transferred to our customers over time. In addition, certain of our hydraulic fracturing equipment ismay be entitled to daily idlereservation fee charges if a customer were to idlereserve committed hydraulic fracturing equipment. The Company recognizes revenue related to idlereservation fee charges on a daily basis as the performance obligations are met.
Acidizing, which is part of our hydraulic fracturing operating segment, involves a well-stimulation technique where acid or similar chemicals are injected under pressure into formations to form or expand fissures. Our acidizing contracts have one performance obligation, satisfied at a point-in-time, upon completion of the contracted service or sale of acid or chemical when control is transferred to the customer. Jobs for these services are typically short term in nature, with most jobs completed in less than a day. We recognize acidizing revenue at a point-in-time, upon completion of the performance obligation.
Our cementing services use pressure pumping equipment to deliver a slurry of liquid cement that is pumped down a well between the casing and the borehole. Our cementing contracts have one performance obligation, satisfied at a point-in-time, upon completion of the contracted service when control is transferred to the customer. Jobs for these services are typically short term in nature, with most jobs completed in less than a day. We recognize cementing revenue at a point-in-time, upon completion of the performance obligation.
Wireline services (including pumpdown) are oil well completion techniques, which are part of the well completions services. Our wireline services utilize equipment with a drum of wireline to deploy perforating guns in the well to perforate the casing, cement, and formation. Once the well is perforated, the well can be fractured. Pumpdown utilizes pressure pumping equipment to pump water into the well to deploy perforating guns attached to wireline through the lateral section of a well. Our wireline contracts with our customers have one performance obligation, which is the contracted total stages, satisfied over time. We recognize revenue over time using a progress output, unit-of-work performed method, which is based on the agreed fixed transaction price and actual stages completed. We believe that recognizing revenue based on actual stages completed faithfully depicts how our wireline services are transferred to our customers over time. In addition, certain of our wireline equipment is entitled to daily equipment charges while the equipment is on the customer’s locations. The Company recognizes revenue related daily equipment charges on a daily basis as the performance obligations are met.
The transaction price for each performance obligation for all our pressure pumpingcompletion services is fixed per our contracts with our customers.
All Other— All other consists of coiledCoiled tubing operations, which areinvolves complementary downhole well completion/remedial services. The performance obligation for these services hashad a fixed transaction price which iswas satisfied at a point-in-time upon completion of the service when control iswas transferred to the customer. Accordingly, we recognizerecognized revenue at a point-in-time, upon completion of the service and transfer of control to the customer.

As of December 31, 2021,2023, the Company had $0.2 million allowance for credit losses. Our allowance for credit losses is based on the evaluation of both our historic collection experience and economic outlook for the oil and gas industry. We evaluated the historic loss experience on our accounts receivable and also considered separately customers with receivable balances that may be negatively impacted by current or future economic developments and market conditions. While the Company has not experienced significant credit losses in the past and has not yet seen material changes to the payment patterns of its customers, the Company cannot predict with any certainty the degree to which the impacts of the COVID-19 pandemic,depressed economic activities, including the potential impact of periodically adjusted borrowing base limits, level of hedged production, or unforeseen well shut-downs may affect the ability of its customers to timely pay receivables when due. Accordingly, in future periods, the Company may revise its estimates of expected credit losses.

Impairment of Long‑Lived Assets — In accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 360, Accounting for the Impairment or Disposal of Long‑Lived Assets, the Company reviews its long‑lived assets to be held and used whenever events or circumstances indicate that the carrying value of those assets may not be recoverable.
An impairment loss is indicated if the sum of the expected future undiscounted cash flows attributable to the asset group is less than the carrying amount of such asset group. In this circumstance, the Company recognizes an impairment loss for the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. No impairment expense was recorded during the year ended December 31, 2023. During the year ended December 31, 2022, we recordedimpairment expense of approximately $57.5 million in connection with our DuraStim® electric-powered hydraulic fracturing equipment. No impairment expense was recorded during the year ended December 31, 2021. Property and equipment impairment loss of $27.5 million and $1.1 million was recorded during the year ended December 31, 2020 relating to our pressure pumping and drilling assets, respectively. Property and equipment impairment loss of $1.2 million and $2.2 million was recorded during the year ended December 31, 2019 relating to our drilling and flowback asset groups, respectively. Our drilling and flowback asset groups are included in the “all other” category in our reportable segment disclosure.
The Company accounts for long‑lived assets to be disposed of at the lower of their carrying amount or fair value, less cost to sell once management has committed to a plan to dispose of the assets.
Goodwill — Goodwill is the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets and liabilities recognized. Goodwill is not amortized. We perform an annual impairment test of goodwill as of December 31, or more frequently if circumstances indicate that impairment may exist. The determination of impairment is made by comparing the carrying amount of a reporting unit with its fair value, which is generally calculated using a combination of market and income approaches. If the fair value of the reporting unit exceeds the carrying value, no further testing is performed. If the fair value of the reporting unit is less

Intangible Assets — Intangible assets consist of customer relationships and trademark/trade name purchased in connection with finite useful livesthe Silvertip Acquisition. In connection with the Silvertip Acquisition, we added intangible assets consisting of $46.5 million of customer relationships and $10.8 million of trademark/trade name. Intangible assets are amortized on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized which is generally on a straight‑line basis over the asset’s estimated useful life.life, which is ten years. No significant residual value is estimated for intangible assets.
Income Taxes — Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of differences between the consolidated financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.
We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, and the results of recent operations. If we determine that we would not be able to fully realize our deferred tax assets in the future, we would record a valuation allowance.
Advertising Expense — All advertising costs are expensed as incurred. For the years ended December 31, 2021, 2020 and 2019, advertising expense was $0.8 million, $0.4 million and $1.2 million, respectively.
Deferred Loan Costs — The Company capitalized certain costs in connection with obtainingthe amendment and restatement of its borrowings,revolving credit facility, including lender, legal, and accounting fees. These costs are being amortized over the term of the related loan using the straight‑line method. Unamortized deferred loan costs associated with loans paid off or refinanced with different lenders are expensed in the period in which such an event occurs. Deferred loan costs are classified as a reduction of

Amortization of deferred loan costs is recorded as interest expense in the statement of operations, and during the years ended December 31, 2021, 20202023, 2022 and 2019,2021, the amount of expense recorded was $0.50.4 million, $0.5$0.8 million and $0.5 million, respectively.
Stock-Based Compensation — The Company recognizes the cost of stock‑basedstock-based awards on a straight‑line basis over the requisite service period of the award, which is usually the vesting period under the fair value method. Total compensation cost is measured on the grant date or modification date, as applicable, using fair value estimates.
Insurance Financing — The Company annually renews its commercial insurance policies, and may choose to either directly pay the insurance premium or finance a portion of the premium. If the Company finances a portion of the premium, a prepaid insurance asset is recorded and amortized monthly over the relevant period.
Concentration of Credit Risk — The Company’s assets that are potentially subject to concentrations of credit risk are cash and cash equivalents and trade accounts receivable. Cash balances are maintained in financial institutions, which at times exceed federally insured limits. The Company monitors the financial condition of the financial institutions in which accounts are maintained and has not experienced any losses in such accounts. The receivables of the Company are with credible operators in the oil and natural gas industries. The Company performs ongoing evaluations as to the financial condition of its customers with respect to trade receivables.
Share Repurchases — All shares of common stock repurchased through the Company's share repurchase program are retired upon repurchase. The Company accounts for the purchase price of repurchased common stock in excess of par value ($0.001 per share of common stock) as a reduction of additional paid-in capital, and will continue to do so until additional paid-in capital is reduced to zero. Thereafter, any excess purchase price will be recorded as a reduction of retained earnings.
Change in Accounting Estimates — Current trends in hydraulic fracturing equipment operating conditions such as larger pads, changes to job design and increased pumping hours per day have resulted in shorter useful lives for certain critical components that are included in our property and equipment assets. These recent trends necessitated a review of useful lives of our critical components like fluid ends, power ends, hydraulic fracturing units and other components in the first quarter of 2023. We determined that the estimated useful life of fluid ends is now less than one year, resulting in our determination that costs associated with the replacement of these components will no longer be capitalized, but instead recorded in inventories and amortized to cost of services over their estimated useful life. We have also shortened the estimated useful lives of power ends to two years from five years and hydraulic fracturing units to ten years from fifteen years. This change in accounting estimates was made effective January 1, 2023 and accounted for prospectively. The net effect of this change for the year ended December 31, 2023, was a $19.1 million decrease in net income, or $0.17 per basic and diluted share, respectively.
Additionally, in connection with the review of our fluid ends and power ends estimated useful life, effective January 1, 2023, we are writing off the remaining book value of power ends that prematurely fail as accelerated depreciation. These write-off amounts were $12.5 million, $11.8 million, $8.4 million and $6.0 million for the three months ended March, 31, 2023, June 30, 2023, September 30, 2023 and December 31, 2023, respectively. However, to conform to prior year presentation, we have presented these write-off amounts within loss on disposal of assets for the year ended December 31, 2023. In 2022 and 2021, we wrote off the remaining book value of prematurely failed and disposed of power ends to loss on disposal of assets.

Total net assets acquired$25,395 

Preliminary estimates of fair values of the assets acquired and the liabilities assumed are based on information available through the issuance of these consolidated financial statements, and the Company is continuing to evaluate the underlying inputs and assumptions used in the valuations. Accordingly, these preliminary estimates are subject to change during the measurement period, which is up to one year from the acquisition date.

The deferred cash consideration of $3.2 million will be used to cover the amount by which the estimated purchase price exceeds the final purchase price, if any. The unused amount is payable to Par Five or its beneficiary on June 1, 2025 and accrues interest at 4.0% per annum. This obligation is shown within other long-term liabilities in our consolidated balance sheets. As of December 31, 2023, the outstanding amount for this obligation was $3.2 million.

The fair value of the assets acquired includes account receivables of $8.7 million. The gross amount due under contracts is $8.7 million, of which none is expected to be uncollectible. The Company did not acquire any other class of receivable as a result of the acquisition of Par Five.

The acquired business contributed revenues of $4.9 million and net income of $1.2 million to the Company for the period from December 1, 2023 to December 31, 2023.

Silvertip Acquisition
On November 1, 2022 (the "Silvertip Acquisition Date"), the Company entered into a purchase and sale agreement with New Silvertip Holdco, LLC, pursuant to which the Company acquired 100% of the outstanding limited liability company interests of Silvertip, a wireline services company in the Permian Basin, in exchange for total consideration of $148.1 million (the "Silvertip Purchase Price") consisting of 10.1 million shares of our common stock valued at $106.7 million, $30.0 million of cash, the payoff of $7.2 million of assumed debt, and the payment of $4.1 million of certain seller closing and transaction costs. The Silvertip Acquisition positions the Company as a more resilient and diversified completions-focused oilfield service provider headquartered in the Permian Basin.
The Company accounted for the Silvertip Acquisition using the acquisition method of accounting. The Silvertip Purchase Price was allocated to the major categories of assets acquired and liabilities assumed based upon their estimated fair value at the Silvertip Acquisition Date. The estimated fair values of certain assets and liabilities, including accounts receivable, require significant judgments and estimates. The measurements of assets acquired and liabilities assumed, are based on inputs that are not observable in the market and thus represent Level 3 inputs.
The following table summarizes the fair value of the consideration transferred in the Silvertip Acquisition and the Silvertip Purchase Price to the fair value of the assets acquired and liabilities assumed (which are included within the accompanying consolidated balance sheet as of December 31, 2022) as of the Silvertip Acquisition Date:

5. FAIR VALUE MEASUREMENTS
Fair value ("FV") is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit price") in an orderly transaction between market participants at the measurement date.
In determining fair value, the Company uses various valuation approaches and establishes a hierarchy for inputs used in measuring fair value that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used, when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions other market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the observability of inputs as follows:
Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment.
Level 2 — Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

4. FAIR VALUE MEASUREMENTS (Continued)
Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Short-term investment— On September 1, 2022, the Company received 2.6 million common shares of STEP Energy Services Ltd. ("STEP") with an estimated fair value of $11.8 million as part of the consideration for the sale of our financial instrumentscoiled tubing assets to STEP. The shares were treated as an investment in equity securities measured at December 31, 2021fair value using Level 1 inputs based on observable prices on the Toronto Stock Exchange and 2020 approximated or equaled their carrying value as reflectedare shown under current assets in our consolidated balance sheets. As of December 31, 2023, the fair value of the short-term investment was estimated at $7.7 million. The fluctuation in stock price resulted in an unrealized loss of $2.5 million and $1.6 million for 2023 and 2022, respectively. Included in the unrealized loss was a gain of $0.1 million and a loss of $0.3 million resulting from non-cash foreign currency translation for the years ended December 31, 2023 and 2022, respectively. The unrealized losses resulting from stock price fluctuation and non-cash foreign currency translation are included in other income (expense) in our consolidated statements of operations. The Company is restricted from selling, transferring or assigning more than 0.9 million shares in any one calendar month.
Assets Measured at Fair Value on a Nonrecurring Basis
Certain assets and liabilities are measured at fair value on a nonrecurring basis. These items are not measured at fair value on an ongoing basis but may be subject to fair value adjustments in certain circumstances. These assets and liabilities include those acquired through the Par Five Acquisition, which are required to be measured at fair value on the acquisition date according to ASC Topic 805, Business Combinations (see Note 4. Business Acquisitions).
Whenever events or circumstances indicate that the carrying value of long-lived assets may not be recoverable, the Company reviews the carrying values of long‑lived assets, such as property and equipment and other assets to determine if they are recoverable. If any long‑lived assets are determined to be unrecoverable, an impairment expense is recorded in the period. No impairment of property and equipment was recorded during the year ended December 31, 2023. We recorded impairment expense of approximately $57.5 million during the year ended December 31, 2022, in connection with our DuraStim® electric-powered hydraulic fracturing pumps that did not meet the manufacturer's specifications or our expectations. There was no impairment of assets during the year ended December 31, 2021.
During the year ended December 31, 2020, we recorded property and equipment impairment loss of approximately $28.6 million in connection with the depressed utilization of our pressure pumping and drilling assets. During the year ended December 31, 2019, we recorded property and equipment impairment loss of approximately $3.4 million in connection with our drilling and flowback assets, in our “all other” segment.

5. FAIR VALUE MEASUREMENTS (Continued)
We generally apply fair value techniques to our reporting units on a nonrecurring basis associated with valuing potential impairment loss related to goodwill, if any. Our estimate of the reporting unit fair value is based on a combination of income and market approaches, Level 1 and 3, respectively, in the fair value hierarchy. The income approach involves the use of a discounted cash flow method, with the cash flow projections discounted at an appropriate discount rate. The market approach involves the use of comparable public companies’ market multiples in estimating the fair value. Significant assumptions include projected revenue growth, capital expenditures, utilization, gross margins, discount rates, terminal growth rates, and weight allocation between income and market approaches. If the reporting unit’s carrying amount exceeds its fair value, we consider goodwill impaired, and the impairment loss is calculated and recorded in the period. There were no additions to or disposalgoodwill during the year ended December 31, 2023. We added $23.6 million of goodwill during the year ended December 31, 2022 (see Note 4. Business Acquisitions). There were no additions to goodwill during the year ended December 31, 2021. We conducted our annual impairment test of goodwill as of December 31, 2023 and determined that no impairment to the carrying value of goodwill for our reporting unit (wireline operating segment) was required. There were no goodwill impairment losses during the years ended December 31, 2021, 20202023, 2022 and 2019. In2021.
The wireline operating segment is the first quarter of 2020,only segment which has goodwill at December 31, 2023 and 2022. The table below sets forth the depressed crude oil prices and crude oil storage challenges facedchanges in the U.S. oilcarrying amount of goodwill.

The Company currently has 3three operating segments for which discrete financial information is readily available: hydraulic fracturing (inclusive of acidizing), cementingwireline and coiled tubing. Thesecementing. These operating segments represent how the Chief Operating Decision MakerCODM evaluates performance and allocates resources.
In December 2021, the Company disposed of 2 turbine generators included in our pressure pumping reportable segment for total cash proceeds of approximately $36.0 million. The net book value of the 2 turbines prior to the disposal was approximately $39.5 million, resulting in loss on disposal of approximately $3.5 million. InOn September 2020, 1, 2022, the Company shut down its drillingcoiled tubing operations and disposed of allits coiled tubing assets to STEP as part of its drilling rigsa strategic repositioning, and ancillaryrecorded a loss on disposal of $13.8 million. The divestiture of our coiled tubing assets did not qualify for approximately $0.5 million. In March 2020, presentation and disclosure as a discontinued operation, and accordingly, we have recorded the Company shut down its flowback operating segment and subsequently disposedresulting loss from the disposal as part of theour loss on disposal of assets for approximately $1.6 million. Our drilling and flowback operations were included in our “all other” category. The shutdownconsolidated statement of operations.
We have historically conducted our business through four operating segments: hydraulic fracturing, wireline, cementing and coiled tubing. Prior to the drilling and flowback operations resulted in a reduction in the numberfourth quarter of our current operating segments to 3. The change in the number offiscal year 2023, our operating segments did not impact ourmet the aggregation criteria and were aggregated into the “Completion Services” reportable segment and our coiled tubing operations (which were divested in September 2022) were shown in the “All Other” category.Effective as of the fourth quarter of fiscal year 2023, we revised our segment reporting as we determined that our three operating segments no longer met the criteria to be aggregated. Our Hydraulic Fracturing and Wireline operating segments meet the criteria of a reportable segment. Our cementing and our divested coiled tubing segments do not meet the reportable segment criteria and are included within the “All Other” category. Additionally, our corporate administrative activities do not involve business activities from which it may earn revenues and its results are not regularly reviewed by the Company’s CODM when making key operating and resource decisions. As a result, corporate administrative expenses have been included under “Reconciling Items.” Prior period segment information reported for the years presented.has been revised to conform to our current presentation.
          In accordance with FASB ASC 280—Segment Reporting, the Company has 1 reportable segment (pressure pumping) comprised of the hydraulic fracturing and cementing operating segments. The coiled tubing operating segment and corporate administrative expense (inclusive of our total income tax expense (benefit), other (income) and expense and interest expense) are included in the "all other" category in the tables below. Total corporate administrative expense for the years ended December 31, 2021, 2020 and 2019 was $38.5 million, $31.6 million and $113.0 million, respectively.
Our hydraulic fracturing operating segment revenue approximated 93.3% 78.5%, 94.2% 89.3% and 95.6%91.6% of our pressure pumping revenue for the years ended December 31, 2023, 2022 and 2021, 2020respectively. Revenue from our wireline operating segment (resulting from the acquisition of Silvertip in 2022) approximated 14.1% and 2019,2.4% of our revenue for the years ended December 31, 2023 and 2022, respectively.
Our cementing operating segment revenue approximated 7.4%, 7.2% and 6.5% of our revenue for the years ended December 31, 2023, 2022 and 2021, respectively. Our coiled tubing revenue approximated 1.1% and 1.9% of our revenue for the years ended December 31, 2022 and 2021, respectively. Our operating segments are subject to inherent uncertainties which may influence our prospective activities. Inter-segment revenues are not material and are not shown separately in the tabletables below.
The Company manages and assesses the performance of the reportable segment by its adjusted EBITDA (earnings(earnings before other income (expense), interest expense, income taxes, depreciation and amortization, stock-based compensation expense, severance and relatedother income or expense, impairment expense, (gain)/gain or loss on disposal of assets and other unusual or nonrecurring expenses or (income))income such as impairment charges, retention bonuses, severance, costs related to asset acquisitions, insurance recoveries, one-time professional fees and legal settlements).

10.12. NET INCOME (LOSS) INCOME PER SHARE
Basic net income (loss) income per common share is computed by dividing the net income (loss) income relevant to the common stockholders by the weighted-average number of shares outstanding during the year. Diluted net income (loss) income per common share uses the same net income (loss) income divided by the sum of the weighted-average number of shares of common stock outstanding during the period, plus dilutive effects of options, performance stock units (“PSUs”) and restricted stock units (“RSUs”) outstanding during the period calculated using the treasury method and the potential dilutive effects of preferred stocks (if any) calculated using the if-converted method.

11.13. SHARE REPURCHASE PROGRAM
On May 17, 2023, the Company's board of directors (the "Board") authorized and the Company announced a share repurchase program that allows the Company to repurchase up to $100 million of the Company's common stock beginning immediately and continuing through and including May 31, 2024. The shares may be repurchased from time to time in open market transactions, block trades, accelerated share repurchases, privately negotiated transactions, derivative transactions or otherwise, certain of which may be made pursuant to a trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act, in compliance with applicable state and federal securities laws. The timing, as well as the number and value of shares repurchased under the program, will be determined by the Company at its discretion and will depend on a variety of factors, including management's assessment of the intrinsic value of the Company's common stock, the market price of the Company's common stock, general market and economic conditions, available liquidity, compliance with the Company's debt and other agreements, applicable legal requirements, and other considerations. The Company is not obligated to purchase any shares under the repurchase program, and the program may be suspended, modified, or discontinued at any time without prior notice. The Company expects to fund the repurchases using cash on hand and expected free cash flow to be generated through May 2024. The Inflation Reduction Act of 2022 ("IRA 2022") provides for, among other things, the imposition of a new 1% U.S. federal excise tax on certain repurchases of stock by publicly traded U.S. corporations such as us after December 31, 2022. Accordingly, the excise tax will apply to our share repurchase program in 2023 and in subsequent taxable years. The current government has proposed increasing the amount of the excise tax from 1% to 4%; however, it is unclear whether such a change in the amount of the excise tax will be enacted and, if enacted, how soon any such change could take effect.
All shares of common stock repurchased under the share repurchase program are canceled and retired upon repurchase. The Company accounts for the purchase price of repurchased shares of common stock in excess of par value ($0.001 per share of common stock) as a reduction of additional-paid-in capital, and will continue to do so until additional paid-in-capital is reduced to zero. Thereafter, any excess purchase price will be recorded as a reduction of retained earnings. During the year ended December 31, 2023, the Company paid an aggregate of $51.7 million, an average price per share of $8.93 including commissions, for share repurchases under the share repurchase program, thereby retiring 5.8 million shares. The Company has accrued $0.4 million in respect of the IRA 2022 repurchase excise tax as of December 31, 2023. As of December 31, 2023, $48.3 million remained authorized for future repurchases of common stock under the repurchase program.

Each PSU earned represents the right to receive either one share of common stock or, as determined by the administrator in its sole discretion, a cash amount equal to the fair market value of one share of common stock or amount of cash on the day immediately preceding the settlement date. The actual number of shares of common stock that may be issued under the PSUs ranges from 0% up to a maximum of 200% of the target number of PSUs granted to the participant, based on our total shareholder return ("TSR") relative to a designated peer group of comparable companies (“Peer Group”), generally at the end of a three-year period. In addition to the TSR conditions, vesting of the PSUs is generally subject to the recipient’s continued employment through the end of the applicable performance period. Compensation expense is recorded ratably over the corresponding requisite service period. The grant date fair value of PSUs is determined using a Monte Carlo probability model. Grant recipients do not have any shareholder rights until performance relative to the peer groupPeer Group has been determined following the completion of the performance period and shares have been issued.

The Tax Cuts and Jobs Act (the "TCJA") included a reduction to the maximum deduction allowed for net operating losses generated in tax years after December 31, 2017, and the elimination of carrybacks of net operating losses. Under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, which modified the TCJA, U.S. federal net operating loss carryforwards ("NOLs") generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such NOLs in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. As of December 31, 2021,2023, the Company had approximately $408.0$296.6 million of U.S. federal NOLs, some of which will begin to expire in 2035. Approximately $219.5$87.7 million of the Company’s U.S. federal NOLs relate to pre-2018 periods. As of December 31, 2021,2023, the Company’s state net operating lossesNOLs were approximately $50.1$48.1 million and will begin to expire in 2024.2030. Utilization of net operating lossNOLs carryforwards may be limited due to past or future ownership changes. As of December 31, 2021,2023, we determined that $1.7$0.6 million valuation allowance was necessary against our state deferred tax assets.

There was no cumulative effect adjustment on beginning retained earnings. We also elected other practical expedients provided by the new lease standard, the short-term lease recognition practical expedient in which leases with a term of twelve months or less will not be recognized on the balance sheet, and the practical expedient to not separate lease and non-lease components for real estate class of assets. Our discount rate was based on our estimated incremental borrowing rate on a collateralized basis with similar terms and economic considerations as our lease payments at the lease commencement.

Description of Lease
In March 2013, we entered into a ten-year real estate lease contract (the “Real"Real Estate Lease”One Lease") with a commencement date of April 1, 2013, as part of the expansion of our equipment yard. The lease is with an entity in which a former director of the Company has a noncontrolling equity ownership interest. For the years ended December 31, 2021, 20202023, 2022 and 2019,2021, the Company made lease payments of approximately $0.40.1 million, $0.4 million and $0.4 million, respectively. The assets and liabilities under this contract are equally allocated betweenincluded in our cementing and coiled tubing segments.Hydraulic Fracturing reportable segment. In addition to the contractual lease period, the contract includes an optional renewal of up to ten years. However, the Company terminated the Real Estate One Lease at the end of the term, March 1, 2023.
We accounted for our Real Estate One Lease as an operating lease. This conclusion resulted from the existence of the right to control the use of the assets throughout the lease term. We did not account for the land separately from the building of the Real Estate One Lease because we concluded that the accounting effect was insignificant.
As part of our expansion of our hydraulic fracturing equipment maintenance program, we entered into a two-year maintenance facility real estate lease contract (the "Maintenance Facility Lease") with a commencement date of March 14, 2022. During the year ended December 31, 2023 the Company made lease payments of approximately $0.3 million. In addition to the contractual lease period, the contract includes an optional renewal for three additional periods of one year each, however, the Company plans to terminate the Maintenance Facility Lease at the end of the term, February 29, 2024. The contract does not include a residual value guarantee, covenants or financial restrictions. Further, the Maintenance Facility Lease does not contain variability in payments resulting from either an index change or rate change.
We accounted for our Maintenance Facility Lease as an operating lease. This conclusion resulted from the existence of the right to control the use of the assets throughout the lease term. We did not account for the land separately from the building of the Maintenance Facility Lease because we concluded that the accounting effect was insignificant. As of December 31, 2023, the weighted average discount rate and remaining lease term was approximately 3.4% and 0.2 years, respectively.
In August 2022 and December 2022, we entered into equipment lease contracts (the "Electric Fleet Leases") for a duration of approximately three years each for a total of four FORCESM electric-powered hydraulic fracturing fleets with 60,000 HHP per fleet. The Electric Fleet Leases contain options to either extend each lease for up to three additional periods of one year each or purchase the equipment at the end of their initial term of approximately 3.0 years or at the end of each subsequent renewal period.
The first of the Electric Fleet Leases (the "Electric Fleet One Lease") commenced on August 23, 2023 when we received some of the equipment associated with the first FORCESM electric-powered hydraulic fracturing fleet. During the year ended December 31, 2023, the Company made lease payments of approximately $2.2 million, including variable lease payments of approximately $0.1 million. During the year ended December 31, 2023, the Company incurred initial direct costs of approximately $14.3 million to place the leased equipment into its intended use, which are included in the right-of-use asset cost related to the Electric Fleet One Lease. The assets and liabilities under this contract are included in our Hydraulic Fracturing reportable segment. In management's judgment the exercise of neither the renewal option nor the purchase option is reasonably assured. In addition to fixed rent payments, the Electric Fleet One Lease contains variable payments based on equipment usage. The Electric Fleet One Lease does not include a residual value guarantee, covenants or financial restrictions.
We accounted for the Electric Fleet One Lease as an operating lease. Our assumptions resulted from the existence of the right to control the use of the assets throughout the lease term. As of December 31, 2023, the weighted average discount rate and remaining lease term was approximately 7.3% and 3.0 years, respectively.
The second of the Electric Fleet Leases (the "Electric Fleet Two Lease") commenced on November 1, 2023 when we received some of the equipment associated with the second FORCESM electric-powered hydraulic fracturing fleet. During the year ended December 31, 2023, the Company made lease payments of approximately $1.0 million, including variable lease payments of approximately $0.03 million.

The Electric Fleet Lease on the fourth FORCESM electric-powered hydraulic fracturing fleet has not yet commenced. We currently do not control the assets under this lease because they are currently being manufactured by the vendor and we have not taken possession of the assets. The delivery of the FORCESM electric-powered hydraulic fracturing fleets is as each fleet is manufactured. We currently expect to receive the remaining equipment associated with the second and third fleets and all equipment associated with the fourth fleet in the first half of 2024. Given that the Company has not yet taken possession of the assets under these leases, the Company has not accounted for the associated right-of-use asset and lease obligation on its balance sheet as of December 31, 2023.

While we cannot reasonably estimate the outcome of the matter at this time, in the opinion of management, the ultimate disposition of the action will not have a materially adverse effect on the Company.
          One of the Sand Suppliers ("SandCo") we entered into an agreement to purchase sand ("Texas Sand") has an indirect relationship with a former executive officer of the Company, because beginning in 2018, the Texas Sand was sourced from a mine located on land owned by an entity in which the former executive officer of the Company has a 44% noncontrolling equity interest. The total sand purchased from SandCo during the three months ended March 31, 2020 (the period the former executive was associated with the Company) was approximately $5.3 million.
As of December 31, 20212023 and 2020,2022, the Company had issued letters of credit of $3.76.0 million and $3.7$6.0 million, respectively, under the ABL Credit Facility in connection with the Company's casualty insurance policy.

           In May 2020, the U.S. District Court for the Western District of Texas consolidated two shareholder derivative lawsuits previously filed against the Company and certain of its current and former officers and directors into a single lawsuit captioned In re ProPetro Holding Corp. Derivative Litigation (the “Shareholder Derivative Lawsuit”). In August 2020, the plaintiffs in the Shareholder Derivative Lawsuit filed a consolidated complaint alleging (i) breaches of fiduciary duties, (ii) unjust enrichment and (iii) contribution. The plaintiffs did not quantify any alleged damages in its complaint but, in addition to attorneys’ fees and costs, they seek various forms of relief, including (i) damages sustained by the Company as a result of the alleged misconduct, (ii) punitive damages and (iii) equitable relief in the form of improvements to the Company’s governance and controls. On September 15, 2021, the Court granted the Company's motion to dismiss the complaint in its entirety, without prejudice.
           On November 19, 2021, the Company received a demand letter from a law firm representing one of the purported shareholders of the Company that previously filed the dismissed Shareholder Derivative Lawsuit. The demand letter alleged facts and claims substantially similar to the Shareholder Derivative Lawsuit. The Board of Directors has constituted a committee to evaluate the demand letter and recommend a course of action to the Board of Directors, and the committee has retained counsel to assist with its review. The committee’s review is ongoing.
In October 2019, the Company received a letter from the SEC indicating that the SEC had opened an investigation into the Company, which followed the SEC’s issuance of a formal order of investigation, and requesting that the Company provide certain information and documents, including documents related to the Company's expanded audit committee review and related events. In November 2021,11, 2022, the Company entered into a settlement with the SEC resolving the investigation. The Company was not required to pay any monetary penalty and has no ongoing undertakings in connection with the settlement.

Environmental and Equipment Insurance
The Company is subject to various federal, state and local environmental laws and regulations that establish standards and requirements for protection of the environment. The Company cannot predict the future impact of such standards and requirements, which are subject to change and can have retroactive effectiveness. The Company continues to monitor the status of these laws and regulations. Currently, the Company has not been fined, cited or notified of any environmental violations that would have a material adverse effect upon its financial position, liquidity or capital resources. However, management does recognize that by the very nature of the Company's business, material costs could be incurred in the near term to maintain compliance. The amount of such future expenditures is not determinable due to several factors, including the unknown magnitude of possible regulation or liabilities, the unknown timing and extent of the corrective actions which may be required, the determination of the Company's liability in proportion to other responsible parties and the extent to which such expenditures are recoverable from insurance or indemnification.

Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
         We maintainThe Company’s management, with the participation of its Principal Executive Officer and Principal Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of December 31, 2023. The term "disclosure controls and procedures," as defined in Rule 13a-15(e) under the Exchange Act, means controls and other procedures that are designed to provide reasonable assuranceensure that the information required to be disclosed by usa company in ourthe reports that we fileit files or submitsubmits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms promulgated by the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to ourthe company’s management, including ourits principal executive officer and principal financial officer,officers, as appropriate to allow timely decisions regarding required disclosure.
         As required by Rule 13a-15(b) under Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the Exchange Act, wecost-benefit relationship of possible controls and procedures. Our Principal Executive Officer and Principal Financial Officer have evaluated under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (asas of December 31, 2023, and have concluded that our disclosure controls and procedures were not effective due to the material weakness described below in “Management’s Report on Internal Control Over Financial Reporting.”
Notwithstanding the conclusion by our Principal Executive Officer and Principal Financial Officer that our disclosure controls and procedures as of December 31, 2023, were not effective, and notwithstanding the material weakness in our internal control over financial reporting described below, our management believes that our financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Management’s Report on Internal Control over Financial Reporting
The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(e) and 15d-15(e)Rule 13a-15(f) under the Exchange Act)Act as a process designed by, or under the supervision of, the Company’s Principal Executive Officer and Principal Financial Officer and effected by the Company’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP.
Management conducted the assessment of the effectiveness of the Company’s internal control over financial reporting based on criteria in the SEC guidance on conducting such assessments as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective atManagement conducted the reasonable assurance level as of December 31, 2021.
Management’s Reportassessment based on Internal Control over Financial Reporting
         The management of ProPetro Holding Corp. is responsible for establishing and maintaining adequate internal control over financial reporting for the Company, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. ProPetro Holding Corp. maintains a system of internal accounting controls designed to provide reasonable assurance, at a reasonable cost, that assets are safeguarded against loss or unauthorized use and that the financial records are adequate and can be relied upon to produce financial statements in accordance with U.S. GAAP. The internal control system is augmented by written policies and procedures, an internal audit program and the selection and training of qualified personnel. This system includes policies that require adherence to ethical business standards and compliance with all applicable laws and regulations.
         There are inherent limitations to the effectiveness of any control system. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Also, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company will be detected. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. The Company intends to continually improve and refine its internal controls.
         Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our internal control over financial reporting as of December 31, 2021 based oncertain criteria established in the 2013 Internal Control—IntegratedControl-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based onin 2013. As a result of this evaluation,assessment, management believesconcluded that, ProPetro Holding Corp. maintained effectiveas of December 31, 2023, our internal control over financial reporting aswas not effective due to the material weakness described below.
Segregation of Duties and Management Review Control
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that a reasonable possibility exists that a material misstatement of our annual or interim financial statements would not be prevented or detected on a timely basis.
The material weakness is related to the Company’s information technology environment whereby the Company did not maintain adequate segregation of duties or sufficient compensating management review controls to effectively mitigate an inadequate system access control configuration in its accounting system in which manual journal entry approvers can modify the entries before posting. This deficiency is solely related to manual journal entries and has no impact on system-generated journal entries flowing through our accounting system and other feeder systems. Due to this control deficiency, other manual-dependent controls were deemed ineffective. Subsequent to the identification of this material weakness, the Company conducted additional procedures and determined that there was no material misstatement in its consolidated financial statements for the year ended December 31, 2021. The2023.
The independent registered public accounting firm, Deloitte & ToucheRSM US LLP, Houston, Texas, United States, Auditor Firm ID #34,#49, has audited the consolidated financial statements as of and for the year ended December 31, 2021,2023, and has also issued their report
87


on the effectiveness of the Company’s internal control over financial reporting, included in this Annual Report under Part II, Item 8 above.
Remediation Plan and Status
The Company has taken, among other items, the following measures to address the material weakness identified:
Evaluated the potential impact of the identified material weakness and accordingly, performed additional testing of certain transactions and journal entries in 2023 to ensure completeness and accuracy of its financial statements, and no material exception was identified.
Tested whether this access resulted in any inappropriate journal entries being recorded or revised and concluded that no such instances occurred.
Implemented a segregation of duties conflict process by limiting the access of certain employees of the Company who are owners of management review controls.
Implemented a technical solution to ensure that access to our system of records adequately limits incompatible duties and strengthened our monitoring and review controls over journal entry processing.
Implemented control activities related to additional independent reviews of manual entries posted in the accounting system and are currently evaluating additional procedures to further strengthen the Company’s overall segregation of duties.
Although we have taken preliminary actions to eliminate the identified material weakness, we will continue to evaluate, test, and implement further actions that will further strengthen the Company’s overall internal controls over financial reporting. Remediation generally requires making changes to how controls are designed and implemented and then adhering to those changes for a sufficient period of time such that the effectiveness of those changes is demonstrated with an appropriate amount of consistency. The measures we are implementing are subject to continued management review supported by confirmation and testing, as well as audit committee oversight. Management remains committed to the implementation of remediation efforts to address the material weakness. We will continue to implement measures to remedy our internal control deficiencies, though there can be no assurance that our efforts will ultimately have the intended effects.
Changes in Internal Control over Financial Reporting
         ThereExcept as described above, there were no changes in our system of internal control over financial reporting (as defined in RulesRule 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 20212023, that have materially affected or are reasonably likely to materially affect, our internal control over financial reporting.
