Item 1A. Risk Factors

Risks Related to our Business.

Demand for our equipment and services is affected by the volatility of oil and natural gas prices.

Oil and natural gas prices affect demand throughout the oil and gas industry, including the demand for our equipment and services. Our business depends in large part on the conditions of the oil and gas industry, and specifically on the capital investments of our customers related to the exploration and production of oil and natural gas. When these capital investments decline, our customers’ demand for our services declines.

The price of oil, a world-wide commodity, is affected by, among other things, the potential of armed conflict in politically unstable areas such as the Middle East as well as the actions of OPEC, an oil cartel which controls approximately 40% of global oil production. OPEC’s actions have historically been unpredictable and can contribute to the volatility of the price of oil on the world market.

Although the production sector of the oil and gas industry is less immediately affected by changing prices, and, as a result, less volatile than the exploration sector, producers react to declining oil and gas prices by curtailing capital spending, which would adversely affect our business. A prolonged low level of customer activity in the oil and gas industry adversely affects the demand for our equipment and services and our financial condition and results of operations.

Reliance upon a large customer may adversely affect our revenues and operating results.

At times our business has had a concentration of one or more major customers. One of our customers, a private E&P company, accounted for approximately 15% of the Company’s revenues in 2025 and 13% of the Company’s revenues in 2024. The customer that exceeded 10% of the Company’s revenues in 2025 and 2024 was primarily associated with the Company’s Technical Services segment. There were no other customers in 2025 and 2024, and no customers in 2023 exceeding 10% of revenues. There were no customers that accounted for 10% or more of accounts receivable as of December 31, 2025, or December 31, 2024. The reliance on a large customer for a significant portion of our total revenues exposes us to the risk that the loss or reduction in revenues from this customer, which could occur unexpectedly, could have a material and disproportionate adverse impact on our revenues and operating results.

14

Our concentration of customers in one industry and periodic downturns may impact our overall exposure to credit risk and cause us to experience increased credit loss allowance for accounts receivable.

Substantially all of our customers operate in the energy industry. This concentration of customers in one industry may impact our overall exposure to credit risk, either positively or negatively, in that customers may be similarly affected by changes in economic and industry conditions. We perform ongoing credit evaluations of our customers and generally do not require collateral in support of our trade receivables. The periodic downturns that our industry experiences may adversely affect our customers' operations, which could cause us to experience increased credit losses for accounts receivable.

Our business depends on capital spending by our customers, many of whom rely on outside financing to fund their operations.

Many of our customers rely on their ability to raise equity capital and debt financing from capital markets to fund their operations. Their ability to raise outside capital depends upon, among other things, the availability of capital, near-term operating prospects of oil and gas companies, current and projected prices of oil and natural gas, and relative attractiveness of competing investments for available investment capital. In addition, continued elevated interest rates continue to impact their ability to borrow cost effectively and potentially constrain the amount of borrowings. These factors are outside of our control, and in the event our customers cannot continue to raise outside capital to fund their operations, RPC’s financial results would be negatively impacted.

RPC’s success will depend on its key personnel, and the loss of any key personnel may affect its revenues.

RPC’s success will depend to a significant extent on the continued service of key management personnel. The loss or interruption of the services of any senior management personnel or the inability to attract and retain other qualified management, sales, marketing and technical employees could disrupt RPC’s operations and cause a decrease in its revenues and profit margins.

We may be unable to compete in the highly competitive oil and gas industry in the future.

We operate within the highly competitive OFS industry. The equipment and services in our industry segments are sold in highly competitive markets, and our revenues and earnings have in the past been affected by changes in competitive prices, fluctuations in the level of activity in major markets and general economic conditions. We compete with the oil and gas industry’s many large and small industry competitors, including the largest integrated oilfield service providers. We believe that the principal competitive factors in the market areas that we serve are product and service quality and availability, reputation for safety, technical proficiency and price. Although we believe that our reputation for safety and quality service is good, we cannot assure you that we will be able to maintain our competitive position.

We may be unable to identify or complete acquisitions, and the completion of significant acquisitions involves integration and other risks.

Acquisitions have been and may continue to be a key element of our business strategy. We cannot assure you that we will be able to identify and acquire acceptable acquisition candidates on terms favorable to us in the future. We may be required to incur substantial indebtedness to finance future acquisitions and also may issue equity securities in connection with such acquisitions. The issuance of additional equity securities could result in significant dilution for our stockholders. We cannot assure you that we will be able to successfully integrate the operations and assets of any acquired business with our own business. Any inability on our part to integrate and manage the growth of acquired businesses could have a material adverse effect on our results of operations and financial condition.

15

Our operations are affected by adverse weather conditions.

Our operations are directly affected by the weather conditions in several domestic regions, including the Gulf of America, the Gulf Coast, the mid-continent, and the Appalachian region. Hurricanes and other storms prevalent in the Gulf of America and along the Gulf Coast during certain times of the year may also affect our operations, and severe hurricanes may affect our customers' activities for a period of several years. While the impact of these storms may increase the need for certain of our services over a longer period of time, such storms can also decrease our customers' activities immediately after they occur. Such hurricanes may also affect the prices of oil and natural gas by disrupting supplies in the short term, which may increase demand for our services in geographic areas not damaged by the storms. Prolonged rain, snow, fire or ice in many of our locations may temporarily prevent our crews and equipment from reaching customer work sites. Due to seasonal differences in weather patterns, our crews may operate more days in some periods than others. Accordingly, our operating results may vary from quarter to quarter, depending on the impact of these weather conditions.

Our ability to attract and retain skilled workers may impact growth potential and profitability.

Our ability to be productive and profitable will depend substantially on our ability to attract and retain skilled workers. Our ability to expand our operations is, in part, impacted by our ability to increase our labor force. A significant increase in the wages paid by competing employers could result in a reduction in our skilled labor force, increases in the wage rates paid by us, or both. The Company and our industry are being affected by shortages of skilled labor. If labor shortages continue or a significant increase in wages occurs, our capacity and profitability could be diminished, and our growth potential could be impaired.

Some of our equipment and several types of materials used in providing our services are available from a limited number of suppliers.

We purchase equipment provided by a limited number of manufacturers who specialize in oilfield service equipment. During periods of high demand, these manufacturers may not be able to meet our requests for timely delivery, resulting in delayed deliveries of equipment and higher prices for equipment. There are a limited number of suppliers for certain materials used in pressure pumping services, our largest service line. While these materials are generally available, supply disruptions can occur due to factors beyond our control. Such disruptions, delayed deliveries, and higher prices may limit our ability to provide services, or increase the costs of providing services, which could reduce our revenues and profits.

We have used outside financing in prior years to accomplish our growth strategy, and outside financing may become unavailable or may be unfavorable to us.

Our business requires a great deal of capital to maintain our equipment and increase our fleet of equipment to expand our operations, and we currently have access to our credit facility to fund our necessary working capital and other capital requirements. Our credit facility provides a borrowing base of $100 million less the amount of any outstanding letters of credit, and bears interest at a floating rate, which exposes us to market risks as interest rates rise. If our existing capital resources become unavailable, inadequate, or unfavorable for purposes of funding our capital requirements, we would need to raise additional funds through alternative debt or equity financings to maintain our equipment and continue our growth. Such additional financing sources may not be available when we need them or may not be available on favorable terms. If we fund our growth through the issuance of public equity, the holdings of stockholders will be diluted. If capital generated either by cash provided by operating activities or outside financing is not available or sufficient for our needs, we may be unable to maintain our equipment, expand our fleet of equipment, or take advantage of other potentially profitable business opportunities, which could reduce our future revenues and profits.Recent increases in interest rates, not withstanding modest interest rate reductions by the US Federal Reserve Board, have increased our cost of borrowing, and further increases could materially adversely affect our ability to fund working capital and other capital requirements on a cost-effective basis, and could and negatively impact our cash flows and profitability.

Our international operations could have a material adverse effect on our business.

Our operations in various international markets including, but not limited to, Africa, Canada, Argentina, Mexico, Latin America and the Middle East are subject to risks. These risks include, but are not limited to, political changes, expropriation, currency restrictions and changes in currency exchange rates, taxes, tariffs, boycotts and other civil disturbances. The occurrence of any one of these events could have a material adverse effect on our operations.

16

Increasing expectations from governments, customers, investors and other stakeholders regarding our environmental, social and governance (ESG) practices may affect our business, may create additional costs for us, or expose us to related risks.

Many companies are receiving greater attention from stakeholders regarding their ESG practices, as well as their oversight of relevant ESG issues. The various stakeholders are placing growing importance on our potential environmental and social issue risk exposure and the impact of our choices. Increased focus on ESG and related decision-making may negatively impact us as customers, investors and other stakeholders may choose not to work with us or may reallocate capital or decline to make an investment as a result of their assessment of our ESG practices. Companies that do not comport with, or do not adapt to, these evolving investor and stakeholder ESG-related expectations and standards, or that are assessed as not having responded appropriately to the growing focus on ESG matters, may have their brand and reputation harmed, and the Company or our stock price may be adversely affected even though we may be in full compliance with all relevant laws and regulations. In addition, changed priorities in terms of governmental interpretation of discrimination and other laws could result in enforcement actions or other litigation regarding the Company’s ESG practices.

We have created and published certain voluntary disclosures regarding ESG matters and will continue to do so from time to time. To the extent that we report Green House Gas (GHG) emissions data, the methodologies that we use to calculate our emissions may change over time based upon changing industry standards. We note that standards and expectations regarding the processes for measuring and counting GHG emissions and GHG emission reductions are evolving, and it is possible that our approach to measuring our emissions may be considered inconsistent with common or best practices with respect to measuring and accounting for such matters. If our approaches to such matters fall out of step with common or best practice, we may be subject to additional scrutiny, criticism, regulatory and investor engagement or litigation, any of which may adversely impact our business, financial condition or results of operation.

Furthermore, the SEC has issued final rules, which are currently stayed pending judicial review, and we cannot predict whether, when, or in what form such rules may ultimately be implemented; however, if implemented as proposed, these rules would, among other matters, establish a framework for reporting climate-related risks. To the extent that any rules ultimately implemented impose additional reporting obligations, we could face increased costs. Separately, the SEC has also announced that it is scrutinizing existing climate change related disclosures in public filings, increasing the potential for enforcement if the SEC were to allege our existing climate disclosures are misleading or deficient. Furthermore, in November 2022, the U.S. Department of Labor (“DOL”) adopted final rules that allow plan fiduciaries to consider climate change and other ESG factors when they select retirement investments and exercise shareholder rights, such as proxy voting. The DOL has announced that it will no longer defend these rules and that it intends to replace the rules, although no action in this regard has been taken, and the rules remain in effect. Should plan investors decide not to invest in us based on ESG factors, our business and access to capital may be negatively impacted. In 2023, the State of California enacted legislation that will require large U.S. companies doing business in California to make broad-based climate-related disclosures starting as early as 2026, and other jurisdictions, domestically and internationally, are also considering various climate change disclosure requirements.

In addition, ESG and climate change issues may cause consumer preference to shift toward other alternative sources of energy, lowering demand for oil and natural gas and consequently lowering demand for our services. In some areas these concerns have caused governments to adopt or consider adopting regulations to transition to a lower-carbon economy. These measures may include adoption of cap-and-trade programs, carbon taxes, increased efficiency standards, prohibitions on the manufacture of certain types of equipment (such as new automobiles with internal combustion engines), and requirements for the use of alternate energy sources such as wind or solar. These types of programs may reduce the demand for oil and natural gas and consequently the demand for our services.

Approaches to climate change and a transition to a lower-carbon economy, including government regulation, company policies, and consumer behavior, are continuously evolving. At this time, we cannot predict how such approaches may develop or otherwise reasonably or reliably estimate their impact on our financial condition, results of operations and ability to compete. However, any long-term material adverse effect on the oil and gas industry may adversely affect our financial condition, results of operations and cash flows.

Risk Management Risks.

Our business has potential liability for litigation, personal injury and property damage claims assessments.

Our operations involve the use of vehicles and heavy equipment and exposure to inherent risks, including accidents, well blowouts, explosions, and fires. If any of these events were to occur, it could result in liability for personal injury and property damage, pollution or other environmental hazards or loss of production. Litigation may arise from an accident or catastrophic occurrence at a location where our equipment and services are used. This litigation could result in large claims for damages. The

17

frequency and severity of such incidents will affect our operating costs, insurability and relationships with customers, employees, and regulators. These occurrences could have a material adverse effect on us. We maintain what we believe is prudent insurance protection. We cannot assure you that we will be able to maintain adequate insurance in the future at rates we consider reasonable or that our insurance coverage will be adequate to cover future claims and assessments that may arise.

Regulatory Risks.

Our operations may be adversely affected if we are unable to comply with regulations and environmental laws.

Our business is significantly affected by stringent environmental laws and other regulations relating to the oil and gas industry and by changes in such laws and the level of enforcement of such laws. We are unable to predict the level of enforcement of existing laws and regulations, how such laws and regulations may be interpreted by enforcement agencies or court rulings, or whether additional laws and regulations will be adopted. The adoption of laws and regulations curtailing exploration and development of oil and gas fields in our areas of operations for economic, environmental, or other policy reasons would adversely affect our operations by limiting demand for our services. We also have potential environmental liabilities with respect to our offshore and onshore operations, and could be liable for cleanup costs, or environmental and natural resource damage due to conduct that was lawful at the time it occurred but is later ruled to be unlawful. We also may be subject to claims for personal injury and property damage due to the generation or disposal of hazardous substances in connection with our operations. We believe that our present operations substantially comply with applicable federal and state pollution control and environmental protection laws and regulations. We also believe that compliance with such laws has had no material adverse effect on our operations to date. However, such environmental laws are changed frequently. We are unable to predict whether environmental laws will, in the future, materially adversely affect our operations and financial condition. Penalties for noncompliance with these laws may include cancellation of permits, fines, and other corrective actions, which would negatively affect our future financial results.

Compliance with federal and state regulations relating to pressure pumping services, including hydraulic fracturing, could increase our operating costs, cause operational delays, and could reduce or eliminate the demand for our pressure pumping services.

RPC’s pressure pumping services are the subject of continuing federal, state and local regulatory oversight. This scrutiny is prompted in part by public concern regarding the potential impact on drinking and ground water and other environmental issues arising from the growing use of hydraulic fracturing. In addition, a committee of the United States House of Representatives investigated hydraulic fracturing practices and publicized information regarding the materials used in hydraulic fracturing. Compliance with federal and state regulations relating to pressure pumping services could increase our operating costs, cause operational delays, and could reduce or eliminate the demand for our pressure pumping services. The U.S. Environmental Protection Agency (EPA) also conducted a study of the environmental impact of hydraulic fracturing practices, and in 2015, issued a report which concluded that hydraulic fracturing had not caused a measurable impact on drinking water sources in the U.S. This and similar conclusions from similar investigations have positive implications for our industry; however, more stringent regulations could be imposed in the future, which could have a material adverse impact on our costs and our business.

Risks Related to our Capital and Ownership Structure.

Our management and directors have a substantial ownership interest, and public stockholders may have no effective voice in the management of the Company.

The Company has elected the Controlled Corporation exemption under Section 303A of the New York Stock Exchange (NYSE) Listed Company Manual. The Company is a Controlled Corporation because a group that includes Amy Rollins Kreisler and Timothy C. Rollins, each of whom is a director of the Company, certain of their family members and certain companies under their control (the Controlling Group), controls in excess of 50% of the Company’s voting power. As a Controlled Corporation, the Company need not comply with certain NYSE rules including those requiring a majority of independent directors, and independent compensation and nominating committees.

RPC’s executive officers, directors and their affiliates hold directly or through indirect beneficial ownership, in the aggregate, approximately 61% of RPC’s outstanding shares of common stock as of February 13, 2026. As a result, these stockholders effectively control the operations of RPC, including the election of directors and approval of significant corporate transactions such as acquisitions and other matters requiring stockholder approval. This concentration of ownership could also have the effect of delaying or preventing a third party from acquiring control over the Company at a premium.

18

The Controlling Group could take actions that could negatively impact our results of operations, financial condition or stock price.

The Controlling Group may from time to time and at any time, in their sole discretion, acquire or cause to be acquired, additional equity or other instruments of the Company, its subsidiaries or affiliates, or derivative instruments the value of which is linked to Company securities, or dispose or cause to be disposed, such equity or other securities or instruments, in any amount that the Controlling Group may determine in their sole discretion, through open market transactions, privately negotiated transactions or otherwise. In addition, depending upon a variety of factors, the Controlling Group may at any time engage in discussions with the Company and its affiliates, and other persons, including retaining outside advisers, concerning the Company’s business, management, strategic alternatives and direction, and in their sole discretion, consider, formulate and implement various plans or proposals intended to enhance the value of their investment in the Company. In the event the Controlling Group were to engage in any of these actions, our common stock price could be negatively impacted, such actions could cause volatility in the market for our common stock or could have a material adverse effect on our results of operations and our financial condition.

Our management and directors have a substantial ownership interest, and the availability of the Company’s common stock to the investing public may be limited.

The availability of RPC’s common stock to the investing public may be limited to those shares not held by the executive officers, directors and their affiliates, which could negatively impact RPC’s stock trading prices and affect the ability of minority stockholders to sell their shares. Future sales by executive officers, directors and their affiliates of all or a portion of their shares could also negatively affect the trading price of our common stock.

Provisions in RPC's Certificate of Incorporation and Bylaws may inhibit a takeover of RPC.

RPC’s certificate of incorporation, bylaws and other documents contain provisions including advance notice requirements for stockholder proposals and director nominations. These provisions may make a tender offer, change in control or takeover attempt that is opposed by RPC’s Board of Directors more difficult or expensive.

Risks Related to Digital Operations, Cybersecurity and Business Disruption.

Our operations rely on digital systems and processes that are subject to cyberattacks or other threats that could have a material adverse effect on our business, consolidated results of operations and consolidated financial condition.

Our operations are dependent on digital technologies and services. We use these technologies and services for internal purposes, including data storage, processing and transmissions, as well as in our interactions with customers and suppliers. Digital technologies are subject to the risk of cyberattacks, both from internal and external threats. Internal threats in cybersecurity are caused by the misuse of access to networks and assets by individuals within the Company by maliciously or negligently disclosing, modifying or deleting sensitive information. Individuals within the Company include current employees, contractors and partners. External threats in cybersecurity are caused by unauthorized parties attempting to gain access to our networks and assets by exploiting security vulnerabilities or through the introduction of malicious code, such as viruses, worms, Trojan horses and ransomware. In response to the risk of cyberattacks, we regularly review and update processes to prevent unauthorized access to our networks and assets and misuse of data. We provide regular security awareness training for appropriate employees, simulate phishing attempts and closely manage the accounts and privileges of all employees and contractors. In addition, we have adopted an established cybersecurity framework that provides significant risk management across several areas. We also maintain an up-to-date incident response plan to quickly address cybersecurity incidents. We have experienced unsuccessful cyberattack attempts to gain unauthorized access to our network. To date, these attacks have not had a material impact on our operations.

If our systems for protecting against cybersecurity risks prove to be insufficient, we could be adversely affected by, among other things, loss of or damage to intellectual property, proprietary or confidential information, or customer, supplier, or employee data, as well as, interruption of our business operations and increased costs required to prevent, respond to, or mitigate cybersecurity attacks. These risks could harm our reputation and our relationships with customers, suppliers, employees and other third parties, and may result in claims against us. In addition, we may not have adequate insurance coverage to compensate for losses from any of the risks listed herein, our existing insurance coverage may not continue to be available on acceptable terms or at all, and our insurers may deny coverage as to any future claims. These risks could have a material adverse effect on our business, consolidated results of operations and consolidated financial condition.

19

Risks Related to Artificial Intelligence

Increased usage of Artificial Intelligence (AI) and machine learning technologies could expose us to operational, safety, cybersecurity, legal and reputational risks and could adversely affect our ability to compete, our operating results and our cash flows.

In an asset- and labor-intensive oilfield services business with geographically dispersed field operations, AI is often used (or is embedded in third-party software platforms we use) to support dispatch and logistics, equipment maintenance planning, inventory and procurement, demand forecasting, pricing and other commercial decision-making, safety and compliance monitoring, cybersecurity threat detection, and administrative functions. Competitors may deploy AI-enabled tools more quickly or effectively than we do, improving their cost structure, responsiveness and utilization and increasing competitive pressure. Conversely, if we do not successfully deploy and govern AI, we may not achieve anticipated improvements in operating efficiency or customer service. Any of these factors could adversely affect our ability to maintain utilization and pricing, could increase costs, and could contribute to greater volatility in our margins and cash flows, particularly during periods of lower customer activity levels. The use of AI technologies is evolving rapidly, and the risks associated with these technologies are difficult to predict and may increase over time.

AI may also increase cybersecurity and confidentiality risks. We have enhanced our security measures, applied a risk-based approach, and collaborated with reliable partners to safeguard data and establish clear ownership rights; however, there is no guarantee that our security measures will protect us against all material risks. We monitor the evolving AI legal landscape, adapting to new regulations to ensure compliance, support innovation, and manage risks. The use of generative AI tools may increase the risk that confidential or proprietary information is inadvertently disclosed or incorporated into third-party systems. If such information is exposed, misused, or becomes subject to unclear ownership or license terms, we could incur remediation costs, contractual liabilities, regulatory penalties and reputational harm. Future AI-related regulations could also affect us even if our internal use remains limited. Governments may enact rules governing automated decision-making, data usage, safety testing, workforce impacts, or transparency requirements applicable to manufacturers or their supply chains. Compliance with such regulations could require changes to the software, systems, or data processes we use, and non-compliance—whether by us or a third-party vendor—could expose us to penalties or reputational harm.

We are implementing a new Enterprise Resource Planning system (ERP), and challenges with the implementation of the system may impact our business and operations.

We are in the process of a multi-year implementation of a new ERP system. The implementation requires the integration of the new ERP system with multiple new and existing information systems and business processes and is being designed to accurately maintain our books and records and provide information to our management teams for the operation of the business. The implementation of our new ERP system requires new procedures and certain modifications to our disclosure controls and procedures and internal control over financial reporting, and it will take time for such procedures and controls to become mature in their operation. If we are unable to adequately implement and maintain procedures and controls relating to our new ERP system, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired and impact our assessment of the effectiveness of our internal controls over financial reporting.

General Risks.

Our common stock price has been volatile.

Historically, the market price of common stock of companies engaged in the oil and gas services industry has been highly volatile. Likewise, the market price of our common stock has varied significantly in the past.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Risk Management and Strategy

RPC approaches cybersecurity as an enterprise-wide risk and has created an accountability framework that includes oversight of cybersecurity risks. We have implemented policies and processes designed to detect, prevent, and respond to cybersecurity incidents. To help guide its overall program, RPC has adopted the Center for Internet Security (CIS) framework, which provides prioritized guidance to help defend systems and networks against the most prevalent cyber-attacks as well as support a Zero Trust architecture.

20

RPC has created a cross-departmental team to screen Company vendors (also known as partners and managed service providers) for vulnerabilities on their own systems and compliance with RPC’s policies and procedures, to mitigate risks potentially caused by third party breaches.

As part of its Standard Operating Procedures, RPC has adopted Incident Response Policy (IRP), Data Classification and Handling Policy, and other policies regarding key areas of information security. These policies are reviewed periodically and updated as needed to address emerging risks or gaps in compliance. The IRP also includes guidance on internal and external escalation in the event of an incident or breach. RPC has not experienced a material cybersecurity incident to date. If a material cybersecurity breach occurs, the incident will be reviewed by the cybersecurity team to determine whether further escalation is appropriate. Any incident assessed as potentially being or becoming material will immediately be escalated for further assessment and reported to designated members of our executive leadership team and, if deemed necessary, the Board of Directors. The IRP provides for consultation with outside legal counsel and our independent registered public accounting firm as appropriate, including on materiality analysis and disclosure matters, to make the final materiality determination regarding disclosure and other compliance decisions.

The Company maintains a cyber liability insurance policy that is designed to cover certain expenses, business losses, business interruption, and fines and penalties associated with a data breach or other similar incident. Cyber liability insurance also provides coverage in the event of a ransomware attack including assistance in the timely remediation of material cyberattacks and incidents.

Our business strategy, results of operations and financial condition have not been materially affected by risks from cybersecurity threats, including as a result of previously identified cybersecurity incidents, but we cannot provide assurance that they will not be materially affected in the future by such risks or any future material incidents. For more information on our cybersecurity-related risks, see Item 1A Risk Factors – Risks Related to Digital Operations, Cybersecurity and Business Disruption of this Annual Report on Form 10-K.

Governance

Role of the Board

On an annual basis, the Board reviews and approves the overall enterprise risk management approach and processes implemented by management to identify, assess, manage, and mitigate risk. The Board has delegated its responsibility for oversight of the Company’s cybersecurity and information security framework and risk management to the Audit Committee. The Audit Committee receives information and updates at least quarterly and actively engages with senior leaders with respect to the effectiveness of the Company’s cybersecurity and information security framework, data privacy, and risk management. In addition, the Audit Committee receives reports summarizing threat detection and mitigation plans, audits of internal controls, training and certification, and other cyber-related priorities and initiatives, as well as timely updates from senior leaders on material incidents relating to information systems security, including cybersecurity incidents. The Audit Committee includes members with experience in risk management, including risks related to cybersecurity.

Role of Management

RPC’s cybersecurity program is overseen by the Chief Information Officer (CIO) as well as several key members of RPC’s Enterprise Technology team. These key leaders collectively have over 50 years of experience in network security, cybersecurity and enterprise risk management.The Chief Executive Officer and CIO receive regular updates on cybersecurity matters, results of mitigation efforts related to existing risks and cybersecurity incident response and remediation. These leaders communicate closely with members of RPC’s Information Security Committee (ISC) which oversees the adopted CIS Control Framework, governs the Company’s information security programs and monitors the effectiveness of the Company’s cybersecurity and technology risk management practices. In addition, ISC provides oversight to align security strategies with business objectives. The Company also maintains business continuity and disaster recovery plans.

Item 2. Properties

RPC owns or leases approximately 80 offices and operating facilities. The Company leases approximately 21,200 square feet of office space in Atlanta, Georgia that serves as its headquarters, a portion of which is allocated and charged to Marine Products Corporation. For additional information see note to the consolidated financial statements titled “Related Party Transactions.” The lease agreement for the headquarters is effective through May 2031. RPC believes its current operating facilities are suitable and adequate to meet current and reasonably anticipated future needs. Descriptions of the major facilities used in our operations are as follows:

Owned Locations

Broussard, Louisiana — Operations, sales and equipment storage yard

Elk City, Oklahoma — Operations, sales and equipment storage yard

Houma, Louisiana — Administrative office

Odessa, Texas — Operations, sales and administrative offices

Channelview, Texas — Pipe storage yard and inspection services

Newcastle, Oklahoma — Operations, sales and administrative offices

El Reno, Oklahoma — Operations, sales and administrative offices

Pleasanton, Texas — Operations, sales and administrative offices

Leased Locations

Midland, Texas — Operations, sales and administrative offices

Seminole, Oklahoma — Pumping services facility

The Woodlands, Texas — Operations, sales and administrative office

Hobbs, New Mexico— Operations, sales and administrative office

Atlanta, Georgia — Headquarters

Item 3. Legal Proceedings

RPC is a party to various routine legal proceedings primarily involving commercial claims, employee liability and workers’ compensation claims and claims for personal injury. RPC insures against these risks to the extent deemed prudent by its management, but no assurance can be given that the nature and amount of such insurance will, in every case, fully indemnify RPC against liabilities arising out of pending and future legal proceedings related to its business activities. RPC is also subject to sales and use tax audits in various jurisdictions. While the outcome of these existing lawsuits, legal proceedings, claims and audits cannot be predicted with certainty, management believes that the outcome of all such proceedings, even if determined adversely, would not have a material adverse effect on RPC’s business or financial condition.

Item 4. Mine Safety Disclosures

Performance Graph

The following graph shows a five-year comparison of the cumulative total stockholder return based on the performance of the stock of the Company, assuming dividend reinvestment, as compared with both a broad equity market index, an industry index and a peer group index. The indices included in the following graph are the Russell 2000 Index (Russell 2000), the Philadelphia Oil Service Index (OSX), and a peer group which includes companies that are considered peers of the Company (the Peer Group). The Company has voluntarily chosen to provide both an industry and a peer group index.

The Company was a component of the Russell 2000 during 2025. The Russell 2000 is a stock index measuring the performance of the small-cap segment of the US equity universe. The components of the index had a weighted average market capitalization in 2025 of $4.6 billion, and a median market capitalization of $987 million. The Russell 2000 was chosen because it represents companies with comparable market capitalizations to the Company, and because the Company is a component of the index. The OSX is a stock index of 15 companies that provide oil drilling and production services, oilfield equipment, support services and geophysical/reservoir services. The Company is not a component of the OSX, but this index was chosen because it represents a large group of companies that provide the same or similar equipment and services as the Company. The companies included in the Peer Group are Halliburton Company, Oil States International, Inc., Patterson-UTI Energy, Inc., Liberty Energy, Inc. and ProPetro Holding Corp. The companies included in the Peer Group have been weighted according to each respective issuer's stock market capitalization at the beginning of each year.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Presentation

The following discussion should be read in conjunction with Selected Financial Data and the consolidated financial statements included elsewhere in this document. See also Forward-Looking Statements on page 3. Discussions of year-to-year comparisons of 2024 and 2023 items that are not included in this Form 10-K can be found in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II, Item 7 on our Annual report on Form 10-K for the year ended December 31, 2024, which Item is incorporated herein by reference.

Overview

RPC, Inc. provides a broad range of specialized OFS primarily to independent and major oilfield companies engaged in exploration, production and development of oil and gas properties throughout the United States, including the southwest, mid-continent, Gulf of America, Rocky Mountain and Appalachian regions, and in selected international markets. The Company’s revenues and profits are generated by providing equipment and services to customers who operate oil and gas properties and invest capital to drill new wells and enhance production or perform maintenance on existing wells.

Several key trends discussed above in Item 1., Business, were key drivers of the Company’s results in 2025:

● Generally lower industry activity, including a 6.3% decline in the rig count.

● The Pintail acquisition described in more detail below.

These and other key trends we expect to impact our future results, including expected ongoing consolidation of OFS as well as E&P companies, expected reduction in volatility of rig counts due to increase in capital discipline in E&P, ongoing geopolitical uncertainties, expectations for increased energy consumption due to the rise of AI, general oversupply of OFS capacity, particularly in pressure pumping, creating a high level of price competition, trend for larger E&Ps to seek out OFS partners who can provide larger scale and newer technology options, a favorable long-term outlook for natural gas demand, potential increases to cost of materials due to tariffs, and our strategy to diversify our service lines are discussed in more detail above under “Item 1, Business Technical Services Segment”; “Industry Overview & Key Themes”; “ Competition”; and “Strategy” above, which are incorporated by reference in this Management’s Discussion and Analysis.

Revenues during 2025 totaled $1.6 billion, an increase of 15.0% compared to 2024. The increase in revenues was primarily due to revenues from recently acquired Pintail of $295.8 million, partially offset by lower pressure pumping activity levels compared to the prior year.

Operating income for 2025 was $44.7 million, a 54.1% decrease compared to the prior year.

Net income for 2025 was $32.1 million, or $0.15 earnings per share compared to net income of $91.4 million, or $0.43 earnings per share in 2024.

Cash flows from operating activities decreased to $201.3 million in 2025 compared to $349.4 million in 2024. During 2025, capital expenditures totaled $148.4 million primarily for capitalized maintenance and upgrades of our existing equipment, coupled with ERP and other IT system upgrades.

As of December 31, 2025, there were no outstanding borrowings under our credit facility.

Pintail Acquisition

As described in more detail in the notes to financial statements, on April 1, 2025, we completed our acquisition of Pintail Alternative Energy, L.L.C. ("Pintail”). Under the acquisition agreement, the consideration for the transaction consisted of: (i) $170 million in cash ("the Closing Cash”), subject to certain adjustments (ii) $25 million of RPC common stock (pursuant to which 4,545,454 shares were issued) (the “Stock Consideration”), and (iii) $50 million in the form of a secured note payable to Houston LP (the "Seller Note”). For further information, see “Acquisition related employment costs” and “Cash Requirements” below.

How We Evaluate Our Operations

We use Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) Adjusted EBITDA, Adjusted EBITDA margin and Free cash flow, all non-GAAP measures, to evaluate and analyze the operating performance of our businesses.

We believe that EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and Free cash flow are important indicators of performance. Adjusted EBITDA is defined as EBITDA, adjusted for unusual (income)/expenses. Adjusted EBITDA margin reflects Adjusted EBITDA as a percentage of revenues. Management believes that EBITDA, Adjusted EBITDA and Adjusted EBITDA margin enable investors to compare the operating performance of our core business consistently over various time periods without regard to changes in our capital structure.Management believes that Free cash flow, which measures our ability to generate needed cash from business operations, is an important financial measure for evaluating RPC’s financial condition. Our definition of Free cash flow is limited, in that it does not represent residual cash flows available for discretionary expenditures, since the measure does not deduct the payments required for debt service and other contractual obligations or payments made for business acquisitions.

EBITDA, 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), and related margins, or any other measure of financial performance presented in accordance with accounting principles generally accepted in the United States of America (GAAP). Similarly, Free cash flow should be considered in addition to, rather than as a substitute for GAAP presentation of net cash provided by operating activities, as a measure of our financial condition.

See “Non-GAAP Financial Measures” below for a reconciliation of EBITDA and Adjusted EBITDA to net income, and Adjusted EBITDA margin to net income margin, the most directly comparable financial measure calculated and presented in accordance with GAAP and a reconciliation of Free Cash Flow to Operating Cash Flow, the most directly comparable financial measure calculated and presented in accordance with GAAP.

Year Ended December 31, 2025, Compared to Year Ended December 31, 2024

Revenues. Revenues of $1.6 billion for 2025 increased 15.0% compared to 2024, with both Technical Services segment and Support Services segment revenues increasing. The increase in revenues was primarily due to revenues from recently acquired Pintail of $295.8 million, partially offset by lower pressure pumping activity levels compared to the prior year. The pressure pumping market remains highly competitive. Management believes the industry continues to be over-supplied and efficiency gains are consistently adding pump hour capacity to the industry. These challenges, as well as a declining rig count, have impacted activity, asset utilization, and pricing.

Technical Services segment revenues of $1.5 billion for 2025 increased 15.8% compared to the prior year. The increase in Technical Services revenue was due primarily to results from recently acquired Pintail, partially offset by a decrease in pressure pumping revenues. Technical Services reported operating income of $68.0 million during 2025 compared to operating income of $89.1 million in 2024. The decrease in Technical Services operating income was primarily due to lower pricing coupled with decreased activity in pressure pumping and several other service lines. Support Services segment revenues for 2025 increased by 1.7% compared to 2024, primarily due to higher activity levels within rental tools. Support Services reported operating income of $13.6 million for 2025 compared to operating income of $15.8 million for 2024. Support Services operating income for 2025 decreased by $2.2 million compared to 2024, due to lower pricing within rental tools.

Cost of revenues. Cost of revenues increased 18.9% to $1.2 billion for 2025 compared to the prior year. Cost of revenues increased primarily due to costs from recently acquired Pintail. Excluding results from Pintail, cost of revenues decreased in line with revenues primarily due to a decrease in expenses consistent with lower activity levels, such as materials and supplies, fleet and transportation and maintenance and repairs expenses. In accordance with Staff Accounting Bulletin (SAB) Topic 11.B, cost of revenues presented on the Consolidated Statements of Operations excludes depreciation and amortization totaling $141.2 million for 2025 compared to $120.6 million in the prior year.

Selling, general and administrative expenses. Selling, general and administrative expenses increased to $175.6 million in 2025 compared to $156.4 million in the prior year. The increase was primarily due to an increase in employment related costs coupled with acquisition related costs and expenses from recently acquired Pintail.

27

Acquisition related employment costs. Acquisition related employment costs of $20.3 million represent certain accounting adjustments related to portions of the Pintail acquisition consideration that are contingent upon continued employment. This includes amortized portions of the Stock Consideration and the Redistribution Payments which are non-cash in nature, as well as the acquisition-related employment obligation asset representing 50% of the Seller Note. See note to the consolidated financial statements titled “Acquisition” for additional information related to these costs.

Depreciation and amortization. Depreciation and amortization increased 21.6% to $161.2 million in 2025, compared to $132.6 million in 2024. Depreciation and amortization increased due to additional fixed assets and intangibles related to the Pintail acquisition, coupled with capital expenditures in the past year.

Gain on disposition of assets, net. Gain on disposition of assets, net was $8.2 million in 2025, consistent with the gain on disposition of assets, net of $8.2 million in 2024. The gain on disposition of assets, net is generally comprised of gains and losses related to various property and equipment dispositions or sales to customers of lost or damaged rental equipment.

Other income, net. Other income, net was $6.4 million in 2025 compared to other income, net of $2.9 million in the prior year. Other income recorded during 2025 included a property insurance recovery of approximately $2.5 million.

Interest expense and interest income. Interest expense was $3.0 million in 2025 compared to $724 thousand in the prior year. Interest expense increased primarily due to interest on the Seller Note issued in conjunction with the Pintail acquisition. See “Cash Requirements” below and Note to the consolidated financial statements titled Acquisition for more information regarding the Seller Note. Interest expense includes interest on the Seller Note, facility fees on the unused portion of the credit facility and the amortization of loan costs. Interest income decreased to $8.4 million compared to $13.1 million in the prior year primarily due to a lower average cash balance, primarily due to the acquisition of Pintail on April 1, 2025 and a decrease in net cash provided by operating activities.

Income tax provision. Income tax provision was $24.5 million during 2025, compared to $21.4 million tax provision in the prior year. The effective provision rate was 43.3% for 2025, compared to an 18.9% effective provision rate for the prior year. The increase in the effective tax rate in 2025 compared to the prior year is due to the significant impact of detrimental permanent and discrete adjustments on a lower pretax income.

Net income, net income margin and diluted earnings per share. Net income was $32.1 million in 2025, or $0.15 diluted earnings per share, compared to net income of $91.4 million in 2024, or $0.43 diluted earnings per share. Net income margin was 2.0% for 2025, compared to 6.5% in 2024.

Adjusted EBITDA and Adjusted EBITDA margin. Adjusted EBITDA was $232.7 million, and Adjusted EBITDA margin was 14.3% in 2025 compared to $233.0 million and 16.5% in 2024.

Cash provided by operating activities and Free cash flow. Cash provided by operating activities decreased to $201.3 million in 2025, from $349.4 million in 2024 primarily due to a decrease in net income, coupled with unfavorable changes in working capital. Free cash flowdecreased to $52.9 million in 2025, from $129.5 million in 2024 primarily due to a decrease in cash provided by operating activities, partially offset by lower capital expenditures.

Non-GAAP Financial Measures

Reconciliation of GAAP and non-GAAP Financial Measures

Disclosed above are non-GAAP financial measures of EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, and Free cash flow. These measures should not be considered in isolation or as a substitute for performance or liquidity measures prepared in accordance with GAAP.

A non-GAAP financial measure is a numerical measure of financial performance, financial position, or cash flows that either 1) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the statements of operations, balance sheet or statement of cash flows, or 2) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented.

Liquidity and Capital Resources

Cash and Cash Flows

The Company’s cash and cash equivalents were $210.0 million as of December 31, 2025, $326.0 million as of December 31, 2024, and $223.3 million as of December 31, 2023.

(In thousands) ​ ​ ​ ​ ​ ​

Net cash provided by operating activities ​ $ 201,331 ​ $ 349,386

Net cash used for investing activities ​ ​ (273,697) ​ ​ (201,551)

Net cash used for financing activities ​ $ (43,635) ​ $ (45,170)

Cash provided by operating activities for the year ended December 31, 2025, decreased by $148.1 million compared to the year ended December 31, 2024, primarily due to a decrease in net income, coupled with unfavorable changes in working capital. Change in working capital was a use of cash of $37.4 million during 2025, compared to a $116.7 million source of cash in the same period last year. The most significant working capital related cash flow during 2025 was a cash use of $32.1 million due to a decrease in unearned revenue due to the satisfaction of performance obligations that were associated with a customer cash prepayment we received in the fourth quarter of 2024. The changes in accounts receivable, accounts payable and the other components were mainly due to the timing of payments and receipts. Working capital in the prior year was impacted favorably by the receipt of a $52.8 million federal income tax refund.

Cash used for investing activities for 2025 increased by $72.1 million compared to 2024, primarily due to cash used to fund the acquisition of Pintail, partially offset by a decrease in capital expenditures. Capital expenditures were $148.4 million for the year ended December 31, 2025, compared to $219.9 million for the year ended December 31, 2024. In the prior year, the Company had expenditures for components of a new Tier 4 dual fuel pressure pumping fleet.

29

Cash used for financing activities for 2025 decreased by $1.6 million primarily due to a decrease in repurchases of the Company’s common shares in the open market, partially offset by the repayment of debt assumed at acquisition of Pintail. The Company paid $35.1 million in dividends and repurchased $2.9 million of common stock in 2025 compared to $34.4 million in dividends paid and $9.9 million of common stock repurchased in 2024.

Financial Condition and Liquidity

The Company’s financial condition remains strong. We believe the liquidity provided by our existing cash and cash equivalents and our overall strong capitalization is sufficient to meet our requirements for at least the next twelve months. Our material cash requirements, including commitments for capital expenditures, as of the end of the latest fiscal period, are set forth below under “Cash Requirements.” The Company’s decisions about the amount of cash to be used for investing and financing activities are influenced by our capital position, and the expected amount of cash to be provided by operations. RPC does not expect to utilize our revolving credit facility to meet these liquidity requirements in the near term.

The Company currently has a $100.0 million revolving credit facility that matures in June 2027. The facility contains customary terms and conditions, including restrictions on indebtedness, dividend payments, business combinations and other related items. The revolving credit facility includes a full and unconditional guarantee by the Company's 100% owned domestic subsidiaries whose assets equal substantially all of the consolidated assets of the Company and its subsidiaries. Certain of the Company’s minor subsidiaries are not guarantors. The Credit Agreement’s maturity date is June 22, 2027, and the interest rate is based on Term Secured Overnight Financing Rate (Term SOFR). In addition, the terms of the agreement have a 1.00% per annum floor for Base Rate borrowings and permits the issuance of letters of credit in currencies other than U.S. dollars. As of December 31, 2025, RPC had no outstanding borrowings under the revolving credit facility, and letters of credit outstanding relating to self-insurance programs and contract bids totaled $18.2 million; therefore, a total of $81.8 million of the facility was available. The Company is currently in compliance with the credit facility financial covenants. For additional information with respect to RPC’s facility, see note to the consolidated financial statements titled Notes Payable.

The Company has a shelf registration statement on Form S-3 filed with the Securities and Exchange Commission (SEC) that expires on May 5, 2028, which permits it to offer common stock, preferred stock, warrants, rights, depositary shares, purchase contracts and units containing two or more of the foregoing, in one or more offerings in an aggregate amount of up to $300 million. The Form S-3 is intended to provide us the flexibility to conduct registered sales of our securities, subject to market conditions and our future capital needs.

During 2025, RPC implemented the provisions of Public Law 119-21, commonly referred to as the One Big, Beautiful Bill Act ("OBBBA”), which resulted in a lower tax obligation due to the 100% bonus depreciation on capital expenditures placed in service after January 19, 2025 and immediate expensing of all domestic research and development costs, that were previously amortized over five years. Implementation of the OBBBA provisions did not have an impact on our effective rate or the Income tax provision in our Consolidated Statements of Operations for the year ended December 31, 2025.

Material Cash Requirements

The Company currently expects capital expenditures to be between $150 million and $180 million in 2026. We expect 2026 capital expenditures to be directed towards capitalized maintenance of our existing equipment and selected growth opportunities as well as the upgrade to our ERP and supply chain systems.

During 2025, the Company continued its multi-year systems transformation program to upgrade its ERP and supply chain systems and began capitalizing some costs associated with ERP implementation. We plan to continue the ERP implementation through a phased approach.

As noted above, the Company issued the Seller Note in connection with the Pintail Acquisition. The Seller Note matures on April 1, 2028, and provides for annual principal payments on the anniversary dates of the acquisition. The first principal payment of $20 million is due on April 1, 2026. Interest on the Seller Note accrues at a variable rate equal to the SOFR for the applicable interest period, plus 2.0% per annum, or where applicable, at a specified default rate. For the full year ended December 31, 2025, interest payments paid on the Seller Note totaled approximately $2.4 million. The Seller Note provides for principal reduction or cancellation upon certain events related to the employment of one of the sellers.

As noted above, as of December 31, 2025, letters of credit outstanding relating to self-insurance programs and contract bids totaled $18.2 million.

30

The Company has total operating and finance lease commitments of approximately $27.4 million, of which approximately $10.3 million matures during 2026. See the note to consolidated financial statements titled “Leases” for more information.

The Company has ongoing sales and use tax audits in various jurisdictions subject to varying interpretations of statutes. The Company has recorded the exposure from these audits to the extent issues are resolved or are probable and reasonably estimable. These audits involve issues that could result in unfavorable outcomes that cannot be currently estimated.

The Company has a stock buyback program to repurchase up to 49,578,125 shares in the open market, including an additional 8,000,000 shares authorized for repurchase by the Board of Directors in 2023. There were no shares repurchased on the open market during 2025, and 12,768,870 shares remained available to be repurchased under the current authorization as of December 31, 2025. The Company may repurchase outstanding common shares periodically based on market conditions and our capital allocation strategies. The stock buyback program does not have a predetermined expiration date. For additional information with respect to RPC’s stock buyback program, see note to the consolidated financial statements titled Cash Paid for Common Stock Purchased and Retired.

On January 27, 2026, the Board of Directors declared a regular quarterly cash dividend of $0.04 per share payable March 10, 2026, to common stockholders of record at the close of business on February 10, 2026. The Company expects to continue to pay cash dividends to common stockholders, subject to industry conditions and RPC’s earnings, financial condition, and other relevant factors.

Management expects to fund the foregoing obligations primarily from operating cash flows and existing cash, with the revolving credit facility providing added flexibility if needed.

Inflation

The Company purchases its equipment and materials from suppliers who provide competitive prices and employ skilled workers from competitive labor markets. If inflation in the general economy increases, the Company’s costs for equipment, materials and labor could increase as well. In addition, increases in activity in the domestic oilfield can cause upward wage pressures in the labor markets from which it hires employees, especially if employment in the general economy increases. Also, activity increases can cause supply disruptions and higher costs of certain materials and key equipment components used to provide services to the Company’s customers. In recent years, the price of labor and raw materials increased while labor shortages caused by the departure of skilled labor from the domestic oilfield industry in prior years. The cost increases have moderated but remain high by historical standards. Additionally, tariffs can impact the absolute costs of materials, as well as cause shifts in production to more domestic production adding inflationary pressures to domestic suppliers. Though the ultimate impact is uncertain, the Company does not currently expect tariffs on goods imported into the U.S. to result in materially higher costs of equipment.

Outlook

The current and projected prices of oil, natural gas and natural gas liquids are important catalysts for U.S. domestic drilling activity and can be impacted by economic and policy developments as well as geopolitical disruptions. RPC believes that oil prices currently remain at levels sufficient to continue drilling and completion activities, however the recent fluctuations of oil prices and potential further volatility could result in the Company’s customers opting to delay completion activity. Long-term, projected higher demand for oil and natural gas should drive increased activity in most of the basins in which RPC operates.

We continue to monitor the supply and demand for our services and the competitive environment, including trends such as increasing customer preferences for more efficient equipment. Increased efficiencies in recent years of oilfield completion services and equipment, particularly in pressure pumping, has inherently contributed to oversupply in the Oilfield Services (OFS) market. We believe that competition will remain intense.

For additional discussion about trends that we expect to impact our results in the future, see “Overview” and “Item 1, Business,” above.

Contractual Obligations

The Company’s obligations and commitments that require future payments include certain non-cancelable leases, purchase obligations, amounts related to the usage of corporate aircraft, ongoing ERP implementation, letters of credit, the Seller Note and

31

other long-term liabilities. We expect to fund these obligations primarily through cash generated from our operations. See note titled “Leases” in the Notes to consolidated financial statements for additional details.

Off Balance Sheet Arrangements

The Company does not have any material off balance sheet arrangements.

Related Party Transactions

See note titled “Related Party Transactions” in the Notes to consolidated financial statements for a description of related party transactions.

Critical Accounting Estimates

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require significant judgment by management in selecting the appropriate assumptions for calculating accounting estimates. These judgments are based on our historical experience, terms of existing contracts, trends in the industry, and information available from other outside sources, as appropriate. Senior management has discussed the development, selection and disclosure of its critical accounting estimates requiring significant judgments and estimates with the Audit Committee of our Board of Directors. The Company believes the following critical accounting estimates involve estimates that require a higher degree of judgment and complexity:

Credit loss allowance for accounts receivable — Substantially all of the Company’s receivables are due from oil and gas E&Ps in the United States, selected international locations and foreign, nationally owned oil companies. Our credit loss allowance is determined using a combination of factors to estimate the risk of uncollectibility so that our receivables are appropriately stated. Our established credit evaluation procedures seek to minimize the amount of business we conduct with higher risk customers. Our customers’ ability to pay is directly related to their ability to generate cash flow on their projects and is significantly affected by the volatility in the price of oil and natural gas. Credit loss allowance for accounts receivable is recorded in selling, general and administrative expenses. Accounts are written off against the allowance when the Company determines that amounts are uncollectible, and recoveries of amounts previously written off are recorded when collected. Significant recoveries will generally reduce the required provision in the period of recovery, thereby causing credit loss allowance to fluctuate significantly from period to period. Recoveries were insignificant in 2025, 2024 and 2023. We record specific provisions when we become aware of a customer's inability to meet its financial obligations, such as in the case of bankruptcy filings or deterioration in the customer's operating results or financial position. If circumstances related to a customer change, our estimate of the realizability of the receivable would be further adjusted, either upward or downward.

The estimated credit loss allowance is based on our evaluation of the overall trends in the oil and gas industry, financial condition of our customers, our historical write-off experience, current economic conditions, and in the case of international customers, our judgments about the economic and political environment of the related country and region. In addition to reserves established for specific customers, we establish general reserves by using different percentages depending on the age of the receivables which we adjust periodically based on management’s judgment and the economic strength of our customers. The net credit loss allowance as a percentage of revenues ranged from 0.4% to 0.8% over the last three years. Increasing or decreasing the estimated general reserve percentage by 0.50 percentage points as of December 31, 2025, would have resulted in a change of approximately $1.3 million in the recorded provision for current expected credit losses.

Insurance expenses — RPC self-insures certain risks related to general liability, workers’ compensation, vehicle, property, and employee health insurance costs, up to policy-specified deductible limits. For employee health insurance, RPC maintains stop-loss coverage to limit its financial exposure on high-cost claims. The estimated cost of claims under these self-insurance programs is accrued as incurred, though actual settlement may occur in future periods. These estimates may be adjusted over time based on claim developments. Any portion of outstanding claims expected to be paid beyond one year is classified as long-term accrued insurance expenses. These claims are monitored, and the cost estimates are revised as developments occur relating to such claims. The Company has retained an independent third-party actuary to assist in the calculation of a range of exposure for these claims using various actuarial methods including paid and incurred loss development, paid and incurred Bornhuetter-Ferguson, case outstanding loss development and expected loss. As of December 31, 2025, the Company estimates the range of exposure to be from $19.1 million to $26.7 million. The Company has recorded liabilities as of December 31, 2025, of $22.8 million, which represents management’s best estimate of probable loss.

Long-lived assets including goodwill —RPC carries a variety of long-lived assets on its balance sheet including property, plant and equipment and goodwill. Impairment is the condition that exists when the carrying amount of a long-lived asset exceeds its fair value. Goodwill is the excess of the cost of an acquired entity over the net of the amounts assigned to assets acquired and liabilities

32

assumed. The Company conducts impairment tests on goodwill annually during the fourth quarter, or more frequently if events or changes in circumstances indicate an impairment may exist. The Company completes either a qualitative or quantitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Assessment of goodwill impairment is conducted at the level of each reporting unit. Technical Services and Support Services, comparing the estimated fair value of each reporting unit to the reporting unit’s carrying value, including goodwill. The fair value of each reporting unit is estimated using an income approach and a market approach. The income approach uses discounted cash flow analysis based on management’s short-term and long-term forecast of operating performance. This analysis includes significant assumptions regarding discount rates, revenue growth rates, expected profitability margins, forecasted capital expenditures and the timing of expected future cash flows based on market conditions. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, an impairment loss is measured and recorded.

In addition, the Company conducts impairment tests on long-lived assets, other than goodwill, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. For the impairment testing on long-lived assets, other than goodwill, a long-lived asset is grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Estimated future undiscounted cash flows expected to result from the use and eventual disposition of the asset group are compared to its carrying amount. If the undiscounted cash flows are less than the asset group’s carrying amount, then the Company is required to determine the asset group's fair value by using a discounted cash flow analysis. This analysis is based on estimates such as management’s short-term and long-term forecast of operating performance, including revenue growth rates and expected profitability margins, estimates of the remaining useful life and service potential of the assets within the asset group, and a discount rate based on weighted average cost of capital. An impairment loss is measured and recorded as the amount by which the asset group's carrying amount exceeds its fair value.

Acquisition of business — In accounting for our acquisitions, we evaluate whether a transaction pertains to an acquisition of assets, or to an acquisition of a business. A business is defined as an integrated set of assets and activities that is capable of being conducted and managed for the purpose of providing a return. Asset acquisitions are accounted for by allocating the cost of the acquisition to the individual assets and liabilities assumed on a relative fair value basis; whereas the acquisition of a business requires assets acquired and the liabilities assumed to be recognized at the acquisition date fair values, separately from goodwill. The excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed, is recorded as goodwill. The Company uses its best estimates and assumptions to accurately value assets acquired, and liabilities assumed at the acquisition date as well as any contingent consideration, where applicable. However, these estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the business acquisition date, the Company may have to record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of a business acquisition’s measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the Consolidated Statements of Operations.

Accounting for business combinations requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for intangible assets, pre-acquisition contingencies and any contingent consideration, where applicable. Although management believes that the assumptions and estimates the Company has made in the past have been reasonable and appropriate, they are based in part on historical experience and information obtained from the management of the acquired companies. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results.

As part of the acquisition of Pintail, the Company recognized customer relationships as an identifiable intangible asset. The fair value of customer relationships was estimated using the multi-period excess earnings method. The valuation of customer relationships involves certain key assumptions including estimated customer attrition rate and required returns on contributory assets. These assumptions involve significant judgment about customer retention patterns and the risk profile of the acquired business. Changes in these assumptions could materially affect the fair value assigned to the customer relationships and the related amortization expense in future periods. See Note titled “Acquisition” in the Notes to Consolidated Financial Statements.

Impact of Recent Accounting Pronouncements

See note titled “Significant Accounting Policies” in the Notes to the consolidated financial statements, which is incorporated herein by reference for a description of recent accounting standards, including the expected dates of adoption and estimated effects on results of operations and financial condition.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The Company is subject to interest rate risk exposure through borrowings on its revolving credit facility and the Pintail Seller Note. As of December 31, 2025, there were no outstanding interest-bearing advances on our credit facility which bore interest at a floating rate.

Additionally, the Company is exposed to market risk resulting from changes in foreign exchange rates. However, since the majority of the Company’s transactions occur in U.S. currency, this risk is not expected to have a material effect on its consolidated results of operations or financial condition.

Item 8. Financial Statements and Supplementary Data

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

To the Stockholders of RPC, Inc.:

The management of RPC, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. RPC, Inc. 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 accounting principles generally accepted in the United States of America. 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 controls system. A controls system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the controls system are met. Also, no evaluation of controls can provide absolute assurance that all control issues and any instances of fraud, if any, within the Company will be detected. Further, the design of a controls system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.

Management has excluded Pintail Alternative Energy, L.L.C ("Pintail”), which the Company acquired in April 2025, from its assessment of internal control over financial reporting as of December 31, 2025. Pintail’s total assets and revenues excluded from management’s assessment represented 17% and 18%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2025.

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 operations of our internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, management’s assessment is that RPC, Inc. maintained effective internal control over financial reporting as of December 31, 2025.

The independent registered public accounting firm, Grant Thornton LLP, has audited the consolidated financial statements as of and for the year ended December 31, 2025, and has also issued their report on the effectiveness of the Company’s internal control over financial reporting, included in this report on page 36.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

RPC, Inc.

Opinion on internal control over financial reporting

We have audited the internal control over financial reporting of RPC, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.

We also have 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, 2025, and our report dated February 27, 2026 expressed an unqualified opinion on those 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, included in the accompanying Management’s Report on Internal Control over Financial Reporting (“Management’s Report”). 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 the 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, 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.

Our audit of, and opinion on, the Company’s internal control over financial reporting does not include the internal control over financial reporting of Pintail Alternative Energy, LLC, a wholly-owned subsidiary, whose financial statements reflect total assets and revenues constituting 17 and 18 percent, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2025. As indicated in Management’s Report, Pintail Alternative Energy, LLC was acquired during 2025. Management’s assertion on the effectiveness of the Company’s internal control over financial reporting excluded internal control over financial reporting of Pintail Alternative Energy, LLC.

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

RPC, Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of RPC, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule included under Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 27, 2026 expressed an unqualified opinion.

Basis for opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of customer relationships related to the acquisition of Pintail Alternative Energy, LLC

As described further in Note 2 to the financial statements, the Company acquired Pintail Alternative Energy, LLC on April 1, 2025 for $181.4 million. As part of the acquisition, the Company acquired identifiable intangible assets, including customer relationships valued at $83.7 million. We identified certain assumptions used in the valuation of customer relationships, specifically the customer attrition rate and discount rate, acquired in the acquisition of Pintail Alternative Energy, LLC as a critical audit matter.

The principal consideration for our determination that the valuation of customer relationships is a critical audit matter is the high degree of auditor judgment necessary in evaluating the customer attrition rate and discount rate, which is used by management in the valuation models used to determine fair value.

Our audit procedures related to the Company’s valuation of customer relationships related to the acquisition of Pintail Alternative Energy, LLC included the following, among others:

Note 1: Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of RPC, Inc. and its wholly owned subsidiaries (RPC or the Company). All significant intercompany accounts and transactions have been eliminated.

Certain prior year amounts have been reclassified to conform to the presentation in the current year.

Common Stock

RPC is authorized to issue 349,000,000 shares of common stock, $0.10 par value. Holders of common stock are entitled to receive dividends when and if declared by the Board of Directors out of legally available funds. Each share of common stock is entitled to one vote on all matters submitted to a vote of stockholders. Holders of common stock do not have cumulative voting rights. In the event of any liquidation, dissolution or winding up of the Company, holders of common stock are entitled to ratable distribution of the remaining assets available for distribution to stockholders.

Preferred Stock

RPC is authorized to issue up to 1,000,000 shares of preferred stock, $0.10 par value. As of December 31, 2025, there were no shares of preferred stock issued. The Board of Directors is authorized, subject to any limitations prescribed by law, to provide for the issuance of preferred stock as a class without series or, if so determined from time to time, in one or more series, and by filing a certificate pursuant to the applicable laws of the state of Delaware and to fix the designations, powers, preferences and rights, exchangeability for shares of any other class or classes of stock. Any preferred stock to be issued could rank prior to the common stock with respect to dividend rights and rights on liquidation.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant estimates are used in the determination of the credit loss allowance, accrued insurance expenses, assessments of long-lived assets and goodwill for impairment. Accounting for acquisition of businesses requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for intangible assets, pre-acquisition contingencies and any contingent consideration, where applicable.

Revenues

RPC recognizes revenues from contracts with its customers based on the amount of consideration it receives in exchange for the services provided. See note to the consolidated financial statements titled Revenues for additional information.

Concentration of Credit Risk

Substantially all of the Company’s customers are engaged in the oil and gas industry. This concentration of customers may impact overall exposure to credit risk, either positively or negatively, in that customers may be similarly affected by changes in economic and industry conditions. The Company provided oilfield services to several hundred customers during each of the past three years. One of our customers, a private E&P company, accounted for approximately 15% of the Company’s revenues in 2025 and 13% of the Company’s revenues in 2024. The customer that exceeded 10% of the Company’s revenues in 2025 and 2024 was primarily associated with the Company’s Technical Services segment. There were no other customers in 2025 and 2024, and no customers in 2023 exceeding 10% of revenues. There were no customers that accounted for 10% or more of accounts receivable as of December 31, 2025, or December 31, 2024.

RPC, Inc. and Subsidiaries

Years ended December 31, 2025, 2024 and 2023

Cash and Cash Equivalents

Highly liquid investments with original maturities of three months or less when acquired are considered cash equivalents. The Company maintains its cash in bank accounts which, at times, may exceed federally insured limits. RPC maintains cash equivalents and investments in one or more large financial institutions, and RPC’s policy restricts investment in any securities rated less than investment grade by national rating services.

Accounts Receivable

The majority of the Company’s accounts receivable are due principally from major and independent oil and natural gas E&P’s. Credit is extended based on evaluation of a customer’s financial condition and, generally, collateral is not required. Accounts receivable are considered past due after 60 days and are stated at amounts due from customers, net of a credit loss allowance.

Credit Loss Allowance for Accounts Receivable

Accounts receivable is carried at the amounts due from customers, reduced by an allowance for estimated amounts that may not be collectible in the future. The estimated credit loss allowance is based on an evaluation of industry trends, financial condition of customers, historical write-off experience, current economic conditions, and in the case of international customers, judgments about the economic and political environment of the related country and region. Accounts receivable balances are written off when determined to be uncollectible and recoveries of amounts previously written off are recorded when collected.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted.
