Forward-Lo oking Statements

Certain statements made in this report that are not historical facts are “forward-looking statements” under the Private Securities Litigation Reform Act of 1995. The words “may,” “should,” “will,” “expect,” “believe,” “anticipate,” “intend,” “seek,” “project,” “estimate,” “focus,” “plan,” “continue,” “likely,” “design,” “strategies,” “outlook,” “trend,” the negative of such terms and different forms thereof (e.g., different tenses or number or principal parts, as well as gerunds and other parts of speech such as adjectives, adverbs and nouns derived therefrom), and similar expressions generally identify forward-looking statements.

Such forward-looking statements may include, without limitation, statements that relate to our business strategy, plans and objectives and our beliefs and expectations regarding future demand for our equipment and services and other events and conditions that may influence the oilfield services market and our performance in the future. Forward-looking statements made elsewhere in this report include statements regarding:

| ● | common drivers of operational and financial success for our Technical Services and our Support Services;

| ● | our belief that Downhole Tools represents a differentiated service line with opportunities for technological innovation and new product development to drive growth;

| ● | our ability to continue to monitor factors that impact current and expected customer activity levels, such as the prices of oil and natural gas, changes in pricing for our services and equipment, and utilization of our equipment and personnel;

| ● | our strategy of utilizing equipment in unconventional basins;

| ● | our expectation that capital expenditures will be $150 million to $180 million during 2026 and our expectation that such expenditures will be directed primarily towards capitalized maintenance of our existing equipment to improve efficiency and selected growth opportunities;

| ● | our intention to continue upgrading our equipment to Tier 4 DGB over time in response to the industry trending toward lower emission and more cost effective dual-fuel assets;

| ● | our belief that our financial and operating discipline have resulted in longevity and financial success in an industry where downturns can have significant financial impacts on operator liquidity and economic sustainability;

| ● | our belief that there is an increased likelihood that a potential rapid rise in the use of artificial intelligence would have significant energy consumption requirements and boost demand for power solutions, many of which use oil and natural gas;

| ● | the attractiveness of the U.S. domestic oilfield due to its oil and natural gas reserves, political stability and downstream energy infrastructure;

| ● | our belief that as a result of increased asset efficiencies, there is a general oversupply of Oilfield Services (OFS) capacity, particularly in pressure pumping, which has created a high level of price competition as companies seek to keep assets utilized;

| ● | our belief that there is potential for M&A activity to continue as well as become more frequent in the smaller exploration and production (E&P) and OFS companies;

| ● | our belief that capital discipline has and should generally reduce the volatility of the drilling rig count over time;

| ● | our plans with respect to investing in electric pressure pumping fleets;

| ● | our belief that the principal competitive factors in the market areas that we serve are price, product availability, and quality of our equipment, service quality, reputation for safety and technical proficiency;

3

​

| ● | our primary objective of creating long-term shareholder value by delivering world-class oilfield services to our customers across all services lines and our plans to achieve this objective by executing on strategic investments, both organic and potential M&A, that we believe will increase our scale, diversify our product offerings, expand our customer base and improve our profitability and cash flow;

| ● | our plans to monitor industry-wide factors that impact customer activity levels, such as the prices of oil and natural gas, competitive activity, E&P activity and capital market trends;

| ● | our operating strategy, our growth strategy, and our capital allocation strategy;

| ● | our key human capital management objectives and our focus on fostering talent in the following areas: diversity and equality; development and training; and compensation and benefits;

| ● | our belief that our patented items in our operations are important, but not indispensable, to our success; our plans to seek patent protection when possible; and our reliance to a greater extent on the technical expertise and know-how of our personnel to maintain our competitive position;

| ● | our belief that EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and Free cash flow are important indicators of performance;

| ● | our belief that the pressure pumping market remains highly competitive;

| ● | our belief that the industry continues to be over-supplied and efficiency gains are consistently adding pump hour capacity to the industry;

| ● | our belief that 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;

| ● | our belief that recent fluctuations of oil prices and potential further volatility could result in customers opting to delay completion activities;

| ● | our belief that long-term, projected higher demand for oil and natural gas should drive increased activity in most of the basins in which we operate;

| ● | our belief that competition will remain intense;

| ● | our belief that the favorable long-term outlook for natural gas demand is sufficient for our customers to maintain natural gas-directed exploration and production activities;

| ● | our plans to continue to monitor the supply and demand for our services and the competitive environment, including trends such as increasing customer preferences for lower emission and more efficient equipment;

| ● | our belief that the growing efficiency with which oilfield completion crews are providing services is a catalyst for the oversupplied nature of the oilfield services market;

| ● | our plans to allocate capital to maintain the capacity of our pressure pumping fleet to offset anticipated fleet retirements and our evaluations of our future investments and option to further transition our asset base toward more efficient dual-fuel or electric equipment;

| ● | the strength of our financial condition;

| ● | our plans with respect to our stock buyback program;

| ● | our belief that the liquidity provided by our existing cash and cash equivalents and our overall strong capitalization will provide sufficient liquidity to meet our requirements for at least the next twelve months;

| ● | our 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;

4

​

| ● | our belief that we do not expect to utilize our revolving credit facility to meet our liquidity requirements in the near term;

| ● | our expectations to continue to pay cash dividends to common stockholders, subject to industry conditions and our earnings, financial condition and other relevant factors;

| ● | estimates made with respect to our critical accounting estimates, including the valuation of customer relationships in connection with the Pintail acquisition, and which critical accounting estimates involve estimates that require a higher degree of judgment and complexity;

| ● | our estimates with respect to a calculation of a range of exposure for claims, which as of December 31, 2025, is $17.8 million to $22.3 million;

| ● | the effect of new accounting standards;

| ● | the effect of the changes in foreign exchange rates on our consolidated results of operations or financial condition;

| ● | our belief that our sources of supply are adequate to secure our demands at competitive prices;

| ● | our belief that our current operating facilities are suitable and adequate to meet current and reasonably anticipated future needs;

| ● | our belief that our ERP system will be implemented through a phased approach with costs being incurred over the next few years;

| ● | our technology and process investments, which reduce the number of employees on a job location and change the roles of the remaining employees in ways that reduce their exposure to safety hazards and our belief that this reduced exposure to active areas of a job location has led to fewer safety incidents;

| ● | our statements that tariffs can impact the absolute costs of materials and shift production to more domestic production, thereby adding inflationary pressures to domestic suppliers;

| ● | our statements about the uncertainty of tariffs and inflation;

| ● | our statements that we do not expect incremental tariffs on goods imported into the U.S. to result in materially higher costs of equipment;

| ● | our statement that adjustments related to property, plant and equipment valuation in connection with Pintail may be material and may impact the valuation of other assets;

| ● | our expectation that the Marine Products Transition Support Services agreement would be cancelled on or about the closing date of the proposed merger pursuant to the Merger Agreement between Marine Products and MasterCraft;

| ● | our expectation that RPC will be entering into a new Transition Support Services agreement with Mastercraft;

| ● | our statements that we may repurchase outstanding common shares periodically based on market conditions and our capital allocation strategies considering restrictions under our credit facility; and

| ● | estimates, assumptions and projections related to our application of critical accounting estimates, including those related to credit losses and allowance, self-insurance, goodwill, and acquisitions, the impact of lawsuits, legal proceedings and claims on our financial position and results of operation.

Such forward-looking statements are based on certain assumptions and analyses made by our management in light of its experience and its perception of historical trends, current conditions, expected future developments and other factors it believes to be appropriate. These statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of RPC to be materially different from any future results, performance or achievements expressed or implied in such forward-looking statements.

​

Risk factors that could cause such future events not to occur as expected include the following:

| ● | the volatility of oil and natural gas prices;

| ● | volatility in demand for our services due to, among other things, fluctuations in price levels of oil and natural gas, activity levels in the oil and gas industry in general, driven in part by customer decisions about capital investment toward the development and production of oil and gas reserves;

| ● | the effects of 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;

| ● | fluctuations in drilling rig count and well completions;

| ● | our concentration of customers in the energy industry and periodic downturns;

| ● | our business depends on capital spending by our customers, many of whom rely on outside financing to fund their operations;

| ● | dependence on our key personnel;

| ● | our ability to identify or complete acquisitions;

| ● | our ability to attract and retain skilled workers;

| ● | some of our equipment and several types of materials used in providing our services are available from a limited number of suppliers;

| ● | whether outside financing is available or favorable to us; increasing expectations from customers, investors and other stakeholders regarding our environmental, social and governance practices;

| ● | our compliance with regulations and environmental laws;

| ● | the impact of OPEC disputes on our operating results;

| ● | possible declines in the prices of oil and natural gas, which tend to result in a decrease in drilling activity and therefore a decline in the demand for our services;

| ● | the ultimate impact of current and potential political unrest and armed conflict in the oil producing regions of the world, including the current conflicts in the Middle East, which could impact drilling activity, adverse weather conditions in oil or gas producing regions, including the Gulf of America;

| ● | the uncertainty with Venezuela;

| ● | competition in the oil and gas industry;

| ● | the Company’s ability to implement price increases;

| ● | the potential impact of possible future regulations on hydraulic fracturing on our business;

| ● | risks of international operations;

| ● | reliance on large customers;

| ● | our operations rely on digital systems and processes that are subject to cyberattacks or other threats;

6

​

| ● | our risk that 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;

| ● | our cash and cash equivalents are held primarily at a single financial institution;

| ● | certain ongoing sales and use tax audits in various jurisdictions that involve issues that could result in unfavorable outcomes that cannot be currently estimated;

| ● | the risk that the proposed merger between Marine Products and MasterCraft will not close, due to failure to obtain regulatory or stockholder approvals or failure to satisfy other conditions of the proposed merger;

| ● | inflation in the general economy, upward wage pressures in the labor markets, supply disruptions, and higher costs of certain materials and key equipment components, and decreased supply of skilled labor;

| ● | changes in assumptions underlying our critical accounting judgments and estimates;

| ● | Diversion of time and attention of our executive officers and other key personnel due to the MPC Merger; and

| ● | See “Risk Factors” on page 14 for a more detailed discussion of these and other factors that may cause actual results to differ from our projections.

RPC is further organized into Technical Services and Support Services, which are its operating segments. As of December 31, 2025, RPC had 2,893 employees.

Business Segments

RPC manages its business as either services offered on the well site with equipment and personnel (Technical Services), or services and equipment offered off the well site (Support Services). The businesses under Technical Services generate revenues based on equipment, personnel operating the equipment and the materials utilized to provide the services. They are all managed, analyzed and reported based on the similarities of the operational characteristics and costs associated with providing the services.

Technical Services include RPC’s oil and gas services that utilize people and equipment to perform value-added completion, production and maintenance services directly to a customer’s well. The demand for these services is generally influenced by customers’ decisions to invest capital toward initiating production in a new oil or natural gas well, improving production flows in an existing formation, or to address well control issues. This operating segment consists primarily of pressure pumping, wireline, downhole tools, coiled tubing and cementing. Customers include major multi-national and independent oil and gas producers and selected nationally owned oil companies. The services offered under Technical Services are high capital and personnel intensive businesses. The common drivers of operational and financial success of these services include diligent equipment maintenance, strong logistical processes, and appropriately trained personnel who function well in a team environment. Technical Services are provided in all of RPC’s principal geographical markets.

Support Services include all of the services that provide (i) equipment offered off the well site without RPC personnel and (ii) services that are provided in support of customer operations off the well site such as classroom and computer training. The equipment and services offered include rental tools, drill pipe and related tools, pipe handling, pipe inspection and storage services. The demand for these services tends to be influenced primarily by customer drilling-related activity levels. The primary drivers of operational success for Support Services are offering safe, high quality and in-demand equipment, as well as meeting customer needs and

Technical Services Segment

Pressure Pumping: 29.8% of 2025 total revenues. Services are provided to customers throughout Texas and the mid-continent regions of the United States, with a concentration in the Permian basin. We primarily provide pressure pumping services to customers to enhance the initial production of hydrocarbons in unconventional horizontal well formations. These formations require high volumes of stimulation fluids using a great deal of pressure pumping horsepower to complete the well. Since unconventional wells transitioned from vertical to a long (often 10,000 to over 20,000 feet) horizontal lateral, they require tools and drilling mechanisms that are flexible and can be steered once they are downhole. For these reasons, unconventional wells require more of RPC’s services, such as coiled tubing services and downhole tools, as described in subsections below.

Hydraulic Fracturing, often synonymous with pressure pumping, is performed to stimulate production of oil and natural gas by increasing the permeability of a shale formation. The fracturing process consists of pumping fluids and sand into a cased and perforated well at sufficient pressure to fracture the formation at desired locations and depths. When the pressure is released at the surface, the fluid returns to the well surface, but the proppant remains in the fracture, thus keeping it open to allow oil and natural gas to flow into the production tubing and to the surface.

RPC’s frac fleets are comprised of high pressure hydraulic pumps, powered by both diesel, dual-fuel and natural gas engines, and ancillary equipment such as hoses, valves and blenders, and operational trailers to house personnel and computerized control systems. Pressure pumping equipment is typically truck or skid-mounted equipment for mobility. The Company ended 2025 with 10 horizontal fleets, of which 3 were Tier 4 DGB (dynamic gas blending, also referred to as dual-fuel as they can utilize both diesel and natural gas) and 3 were Tier 4 Diesel. Tier 4 is a set of regulations from the US Environmental Protection Agency (EPA) that aims to reduce harmful emissions from engines and generators. The Company intends to continue upgrading its equipment to natural gas burning over time in response to the industry trending toward lower emission and more cost effective dual-fuel assets but does not intend to increase its overall number of frac fleets.

Downhole Tools: 24.2% of 2025 total revenues. Services and proprietary downhole motors and other specialized tools, such as fishing devices, are provided to drilling and production operators to enable casing perforation and bridge plug drilling at the completion stage of an oil or gas well. Products are also used during workover operations and new market applications such as plug & abandonment, geothermal, and others. The services that Thru Tubing Solutions (TTS) provides are often proprietary solutions developed by the Company, for which the Company maintains an active intellectual property and patent program. Management believes Downhole Tools represents a differentiated service line with opportunities for technological innovation and new product development to drive growth. Examples of newly introduced products include a 3½ inch high performance downhole motor, as well as UnPlug, a proprietary alternative solution to traditional bridge plugs using perforation pods to reduce inefficiencies and technical risks associated with traditional bridge plugs.

Wireline: 19.4% of 2025 total revenues. Services involve unwinding and lowering a spooled wire into a well, conveying various types of tools or equipment. Slick or braided lines are non-conductive and primarily for jarring objects into or out of a well, as in

8

​

fishing or plug-setting operations. Electric lines carry a conductor line into a well allowing the use of electrically-operated tools such as perforators and bridge plugs. Wireline services can also be an integral part of the plug and abandonment process near the end of the life cycle of a well. Effective April 1, 2025, the Company acquired Pintail Completions, a leading provider of oilfield wireline perforating services in the Permian basin. The Company’s wireline revenues increased during 2025 primarily due to the effect of owning Pintail for the partial year.

Coiled Tubing: 9.3% of 2025 total revenues. Services involve the injection of a flexible steel pipe thousands of feet in length into a wellbore to conduct a variety of downhole tasks. Coiled tubing’s flexibility allows it to be steered through horizontal wellbores, while also being strong enough to convey tools or motors at the end of the tube. The hollow tube can convey fluid which powers a motor or may be needed to clean out a wellbore. Coiled tubing units are effective over great distances making them ideal for completion activities in the U.S. domestic market, where lateral lengths have been increasing.

Cementing: 6.4% of 2025 total revenues. The process of cementing includes developing a cement slurry formulated for a well’s unique characteristics, pumping the cement through the wellbore and into the space between the well casing and well bore. The pumping assets used in deploying cement are the same/similar to the equipment used in hydraulic fracturing, making these operations complementary to our pressure pumping service line. The cement creates a barrier to protect the casing and prevent environmental contamination. In addition to uses for completing a new well, cementing can also be used to plug a well at the end of its life cycle.

Snubbing. Services involve using a hydraulic workover rig that permits an operator to repair damaged casing, production tubing and downhole production equipment while maintaining pressure on the well to minimize operational disruptions.

Nitrogen. Both oilfield customers and industrial users outside of the oilfield use these services to, for example, clean drilling and production pipe or purge non-oilfield industrial pipelines.

Well Control. Services include responding to and controlling oil and gas well emergencies, including blowouts and well fires, as well as supply the equipment, expertise and personnel necessary to restore affected oil and gas wells to production so that drilling operations can resume as promptly as safety permits.

Support Services Segment

Rental Tools: 4.1% of 2025 total revenues. The Company rents specialized equipment for use with onshore and offshore oil and gas well completion, drilling and workover activities. The Company offers a broad range of rental tools including drill pipe and associated handling tools, blowout preventers and a variety of tool assemblages that provide well control. The equipment needed is in large part determined by the geological features of the production zone and the size of the well. Given the potentially significant range of equipment needs, operators and drilling contractors often find it more economical to supplement their tool and tubular assets with rental items instead of owning a complete set of assets.

Oilfield Pipe Inspection Services, Pipe Management and Pipe Storage. We provide in-house inspection services, inventory management and process control of tubing, casing and drill pipe for major oil companies and pipe producers.

Well Control School. Provides industry and government accredited training for the oil and gas industry, delivering various formats including conventional classroom training and interactive online training.

Refer to the note to the consolidated financial statements titled Business Segment and Entity Wide Disclosures for additional financial information on our business segments.

Customers

RPC’s principal customers consist of major and independent oil and natural gas producing companies and can range in size from small and independent E&Ps to large (often public) integrated E&Ps. Smaller customers, often referred to as “spot” or “semi-dedicated” are generally less consistent in terms of demand for services but can increase their activities significantly during upcycles. These customers also often rely on OFS companies to provide materials, logistical support and expertise. These customers are typically highly price-sensitive and generally less focused on new equipment and ESG-related trends. Large customers have scale and often contract with OFS companies for “dedicated” fleets and offer more consistent demand and visibility. Their scale also means they can build their own infrastructure for power and water, acquire and develop high quality acreage due to access to capital, and invest in new technologies (both equipment and IT). RPC’s pressure pumping business is oriented towards providing services, materials, logistics and expertise to its customers in the Permian basin, while other service lines, such as downhole tools, cementing, coiled tubing and rental tools service have broad customer size and U.S. oil and gas basins exposure.

​

Sales are generated by RPC’s business unit specific sales forces and through referrals from existing customers. We monitor the financial condition of these customers, their capital expenditure plans, and other indications of their drilling and completion activities. Due to the short lead time between ordering services or equipment and providing services or delivering equipment, there is no significant sales backlog.

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.

Suppliers

The Company’s suppliers mainly provide equipment and materials used across our service lines. We purchase hydraulic fracturing fleets, including pumps and ancillary components, trucks, sand, chemicals, and cement to support our pressure pumping and cementing service lines. We also procure flexible steel pipe used in coiled tubing. Generally speaking, there are multiple suppliers for our key equipment and materials needs and we believe that these sources of supply are adequate to secure our demands at competitive prices.

Industry Overview & Key Themes

RPC provides its services primarily to domestic customers through a network of facilities strategically located to serve oil and gas drilling and production activities of its customers in Texas, the mid-continent, the southwest, the Gulf of America, the Rocky Mountain and the Appalachian regions. Demand for RPC’s services in the U.S. is volatile and fluctuates with current and projected price levels of oil and natural gas and activity levels in the oil and gas industry. Customer activity levels are influenced by their decisions about capital investment toward the development and production of oil and gas reserves. Over the years, the oil and gas industry’s cyclical nature has resulted in many OFS companies going bankrupt, ceasing operations, or being forced to get acquired. The Company believes its financial and operating discipline have resulted in longevity and financial success in an industry where downturns can have significant financial impacts on operator liquidity and economic sustainability.

Rig count. During 2025 the average U.S. rig count decreased 6.3% to 562 compared to the prior year. While oil and gas industry demand is influenced by many factors, the rig count is often used as a proxy for current and future industry activity. Oil and gas industry activity levels have historically been volatile, experiencing multiple cycles. The most significant recent downturn occurred following the onset of the COVID pandemic, with August 2020 marking the lowest U.S. domestic rig count in U.S. oilfield history at 250. Since that point, the industry began to rebound with strong U.S. economic activity, with the rig count reaching an average of 723 in 2022 and 688 in 2023, before trending even lower and averaging 600 during 2024. Over the past several years, there has been oil and gas price volatility sparked by uncertainties related to the Russian invasion of Ukraine, tensions in the Middle East and continued uncertainty from OPEC+ regarding production levels, and additional uncertainty with Venezuela. Furthermore, there is an increased likelihood that a potential rapid rise in the use of artificial intelligence would have significant energy consumption requirements and boost demand for power solutions, many of which use oil and natural gas. Management believes these factors reinforce the attractiveness of the U.S. domestic oilfield due to its oil and natural gas reserves, political stability and downstream energy infrastructure.

Since the majority of RPC’s services are utilized at the completion stage of an oil or gas well’s life cycle, the Company closely monitors well completion trends in the U.S. domestic oilfield. As recently reported by the U.S. Energy Information Administration, reported well completions totaled 11,809 in 2025, a decrease of approximately 1% compared to 2024. Fluctuations in the prices of commodities, particularly the price of oil, and activity levels as measured by well completions, significantly impact RPC’s financial results.

Efficiencies in pressure pumping. In the past decade, there have been significant improvements in the efficiency of OFS, with the end result being more oil and natural gas produced with less equipment. Several factors have contributed to asset efficiency, including the industry’s ability to accurately identify high yielding formations, drill faster and more effectively, complete wells more quickly, and extract the same amount of oil and natural gas with fewer rigs and service equipment. Pressure pumpers have also significantly increased pump hours per day, often to 20 to 22 of 24 hours, resulting in assets being “burned” faster and requiring quicker capital investment cycles. Furthermore, more wells are being drilled per pad, or site, each well is being drilled with longer laterals, now often extending several miles, and more stages are being completed within each lateral. All of these factors are increasing hydrocarbon output without creating a correlated increase in cost; however, cost efficiency savings have been disproportionately realized by the E&Ps rather than oilfield service companies. As a result of increased asset efficiency, the Company believes there is a general oversupply of OFS capacity, particularly in pressure pumping, which has created a high level of price competition as OFS companies seek to keep assets utilized.

Consolidation of E&Ps. The oil and gas industry is capital intensive and cyclical. As a result, operating and financial scale have significant benefits related to acquiring attractive land, investing in assets and infrastructure to efficiently extract hydrocarbons, leveraging scale across the value chain, and generating financial leverage to drive investor returns. The recent trend of consolidation among mid-to-large E&Ps has resulted in a more concentrated pool of larger, more powerful E&P companies. Also, as a result of E&P consolidation, there can be significant changes in an OFS company’s customer base, with customers often being acquired (risking loss of business) or making acquisitions (potential customer gains) across service lines. There is the potential for M&A activity to continue as well as become more frequent in the smaller E&P and OFS market.

Capital discipline by E&Ps. During the past cycle, E&P companies have taken a more disciplined approach to capital allocation of operating and free cash flow. They are maintaining steadier operations and not significantly accelerating or decelerating investment with commodity price cycles and providing a more significant and consistent return of capital to shareholders. This has taken the form of both dividends and share buybacks. This level of discipline is intended to boost overall investor returns, in part by limiting activity volatility and enabling more consistent free cash flow generation available to distribute. As a result, many large E&Ps are focused on developing and securing OFS partners who can meet their needs for scale and types of equipment across their large asset base. While the rig count has trended lower due to the efficiencies discussed above, capital discipline has reduced and should generally continue to reduce the volatility of the rig count over time.

Increased adoption of low-emission equipment. Pressure pumping requires emission-intensive equipment as it has historically been powered solely or primarily by diesel fuel. However, in recent years DGB and electric powered fleets have been increasingly adopted. Electric powered fleets use electric motors powered by lower-cost energy sources (e.g., natural gas converted on-site, compressed natural gas, or grid-supplied electricity) and offer reduced emissions compared to diesel fuel or DGB equipment. Electric assets are often desired by customers, especially large public companies, to achieve their ESG goals, while smaller independent E&Ps often place less value on ESG-related benefits. To date, RPC has not invested in electric fleets but is considering future investments in this area.

Volatility of natural gas prices. Increased domestic consumption and exporting of natural gas in the United States has supported increased natural gas production. The Company believes the favorable long-term outlook for natural gas demand is sufficient for our customers to maintain natural gas-directed E&P activities.

Competition

RPC operates within the highly competitive OFS industry. We offer our services and equipment in highly competitive markets, and the revenues and earnings generated are affected by changes in competitive prices for our services with supply and demand dynamics that can change rapidly. RPC competes with many large and small oilfield industry competitors, including the largest integrated OFS companies. The Company believes that the principal competitive factors in the market areas that it serves are price, product availability and quality of our equipment, service quality and reputation for safety and technical proficiency.

Following a period of strong demand and favorable pricing trends when the OFS industry rebounded off the COVID lows, pricing has become far more competitive. In recent years, improving completion services efficiency has served to increase effective capacity, and the Company believes current supply of most OFS exceeds demand. This has had the most significant impact on the Company’s pressure pumping service line, though all the Company’s Permian-focused operations have faced increased competition from assets shifting into the region from gassy basins where activity has been weak. By nature, OFS companies have high fixed costs and pricing competition to keep assets utilized is common.

​

The oil and gas services industry includes dominant global competitors including, among others, Halliburton Company, Baker Hughes Company, and Schlumberger Ltd. The industry also includes a number of other publicly traded peers whose operations are more similar to RPC, including Liberty Energy, Inc., NCS Multistage Holdings, Inc., Nine Energy Services, Patterson-UTI Energy, Inc., ProFrac Holding Corp. and ProPetro Holding Corp., as well as numerous smaller, privately owned competitors. Increased demand for larger-scale and newer technology solutions, as well as business combinations among large oil and gas companies, are driving consolidation of our competitors in certain service lines.

Strategy

RPC’s primary objective is to create long-term shareholder value by delivering world-class OFS to our customers across all service lines, while exercising capital discipline and employing a conservative operational and financial approach. To achieve this objective, we plan to execute strategic investments, both organic and potential M&A, that we believe will increase our scale, diversify our product offering, expand our customer base and improve our profitability and cash flow. In assessing RPC’s strategy, financial condition and operating performance, management generally reviews results and trends related to revenues, asset utilization, pricing, cost structure, profitability, cash flows and the return on our invested capital. We also monitor industry-wide factors that impact customer activity levels, such as the prices of oil and natural gas, competitive activity, E&P activity and capital markets trends.

Our strategies can be broken down into 3 categories: operating, growth and capital allocation.

Operating strategy

| ● | Drive a culture of highly engaged, empowered, and appropriately incentivized employees

| ● | Provide safe, high quality, well-maintained, in-demand equipment and services to our customers through highly trained personnel and strong logistical support processes

| ● | Maintain a flexible cost structure that can respond quickly to volatile industry conditions and business activity levels

| ● | Optimize asset utilization to leverage direct and overhead costs with a focus on profitability and a bias to avoid burning our assets on low-return projects – i.e., idle fleets as appropriate

| ● | Develop new products and offer specialized services to differentiate ourselves in the marketplace

Growth strategy

| ● | Remain highly disciplined with respect to adding new incremental revenue-producing equipment

| ● | Invest selectively in our key service lines to upgrade technologies and capabilities

| ● | Acquire high-quality companies or assets that would increase our scale, diversify our key service lines, bolster our competencies, expand our customer base and deliver attractive financial returns; due to the fragmented nature of the oil and gas services industry, RPC believes a number of suitable acquisition opportunities exist

| ● | Direct growth investments toward domestic (versus international) operations because of attractive activity levels, competitive positioning and lower geopolitical risks

Capital allocation strategy

| ● | Maintain a conservative and low-cost capital structure, with an appropriate use of debt financing, to sustain operational strength and liquidity during industry downturns

| ● | Balance the use of cash invested in the Company (both organic and potential M&A) and returned to stockholders with strong alignment of management and shareholder interests

| ● | Continue paying regular quarterly dividends, though we do not currently intend to steadily grow the regular dividend, nor do we have a target payout ratio of net income or cash flow to dividends; given the capital intensity and cyclical nature of the business, we do not plan to return significant excess cash to investors through special dividends

12

​

| ● | Maintain a share buyback program to opportunistically repurchase stock in the open market in compliance with the federal securities laws and the applicable exchange listing requirements, if the Company believes our common stock represents an exceptional value

Human Capital

The table below shows the number of employees at December 31, 2025, and 2024:

​ | ​ | ​ | ​ | ​
At December 31, | ​ ​ ​ | 2025 | ​ ​ ​ | 2024
Employees |  | 2,893 |  | 2,597

​

The Company operates in a cyclical business where financial performance and headcount are influenced by, among other things, changes in oil and natural gas prices. The Company’s key human capital management objectives are focused on fostering talent in the following areas:

Workplace Inclusion - The company is committed to fostering a diverse and inclusive workforce, where employees collaborate toward a shared purpose. We uphold strong values, cultivate meaningful relationships, and maintain consistency in leadership and management. As part of our commitment to diversity, we actively recruit and hire recently discharged military personnel. The Board of Directors oversees these efforts through the Human Capital Management and Compensation Committee, which monitors compliance with applicable non-discrimination laws pertaining to race, gender, and other protected classes. The Committee regularly monitors these matters and provides updates to the Board as needed, with a minimum annual review.

Development and Training - The Company’s management team and all its employees are expected to exhibit and promote honest, ethical and respectful conduct in the workplace. We have implemented and maintain a Code of Conduct to provide guidance for everyone associated with the Company, including its employees, officers, and directors (the Code). The Code prohibits unlawful or unethical activity, including discrimination, and directs our employees, officers, and directors to avoid actions that, even if not unlawful or unethical, might create an appearance of illegality or impropriety. The Code is updated annually and certain employees at the supervisory level and above are required to review the Code each year. Any reported non-compliance is followed up on and resolved, as appropriate. In addition, the Company provides annual training for preventing, identifying, reporting, and ending any type of unlawful discrimination. We also have escalation policies in place to address various issues including employee discrimination. The Company also provides a wide variety of opportunities for professional growth for all employees with in-classroom and online training, on-the-job experience, and counseling.

Compensation and Benefits - The Company focuses on attracting and retaining employees by providing compensation and benefit packages that are competitive in the market, taking into account the location and responsibilities of the job. We provide competitive financial benefits such as a 401(k) retirement plan with a company match and generally grant awards of restricted stock for certain of our salaried employees. We provide our employees and their families with access to a variety of innovative, flexible, and convenient health and wellness programs that support their physical and mental health by providing tools and resources to help them improve or maintain their health status.

RPC has always believed in the long-term value of education and has demonstrated this belief through a college scholarship program for the children of employees. This program, which awards four-year college scholarships based on merit, parents' tenure and need, has invested more than $1.5 million to support hundreds of children of employees as they earn college degrees. A number of these college graduates have come to work for RPC and have followed their parents to become valuable employees.

RPC and its subsidiaries have regularly participated in efforts to support the communities in which we live. We have participated in the United Way Campaign in the city in which our corporate headquarters are located for more than 30 years. In addition, we have sponsored several emergency relief efforts following natural disasters, such as hurricanes and tornados, in communities in which our field offices are located.

Safety - The Company adheres to a comprehensive safety program to promote a safe working environment for its employees, contractors and customers at its operational locations and active job sites. This program complies with applicable regulatory guidelines for oilfield operations and is enhanced by our analysis of workplace-related incidents and evolving preventative measures. We monitor our workplace safety record and compare it to industry benchmarks and our internal metrics to find areas for improvement.

RPC is making technology and process investments which reduce the number of employees on a job location and change the roles of the remaining employees in ways that reduce their exposure to safety hazards. We believe that this reduced exposure to active areas of a job location has led to fewer safety incidents.

​

Governmental Regulation

RPC’s business is affected by state, federal and foreign laws and other regulations relating to the oil and gas industry, as well as laws and regulations relating to worker safety and environmental protection. RPC cannot predict the level of enforcement of existing laws and regulations or how such laws and regulations may be interpreted by enforcement agencies or court rulings, whether additional laws and regulations will be adopted, or the effect such changes may have on it, its businesses or financial condition. More stringent environmental standards compel the Company to buy more expensive equipment to meet those standards and also renders older equipment obsolete.

In addition, our customers are affected by laws and regulations relating to the exploration and production of natural resources such as oil and natural gas. These regulations are subject to change, and new regulations may curtail or eliminate our customers’ activities. We cannot determine the extent to which new legislation may impact our customers’ activity levels, and ultimately, the demand for our services.

Intellectual Property

RPC uses several patented items in its operations which management believes are important, but are not indispensable, to RPC’s success. Although RPC anticipates seeking patent protection when possible, it relies to a greater extent on the technical expertise and know-how of its personnel to maintain its competitive position.

Availability of Filings

RPC makes available, free of charge, on its website, www.rpc.net, its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports on the same day they are filed with the Securities and Exchange Commission.

​

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.

​

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.

​

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.

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.

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

​

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

​

​

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.

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.

| ● | Lower oil prices, which limits the profit incentive for our customers to use our (and our competitors) oilfield services, including pressure pumping and other ancillary product and service offerings.

| ● | Continued efficiencies of oilfield equipment allowing the industry to extract the same or more hydrocarbons with the same or fewer assets. This has resulted in an oversupply of OFS capacity in the market and led to increased price competition.

| ● | Trend toward client preference for lower emissions equipment, typically dual fuel or electric assets; the Company has multiple Tier 4 dual fuel frac fleets which have maintained stronger utilization than legacy Tier 2 assets. The Company does not currently offer electric frac fleets.

| ● | E&P consolidation (See section titled Industry Overview and Key Themes in Item 1., Business, for more detail) has resulted in the loss of some customers.

| ● | 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 flow decreased 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.

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

​

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.

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.

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 INTER NAL 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 2013 Internal 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 INDEPEN DENT 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:

37

​

| ● | We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company’s relevant controls to value acquired intangible assets, including the Company’s controls over the selection and review of the appropriateness of the customer attrition rate and discount rate used in determining the fair value of customer relationships.

| ● | We tested the completeness and accuracy of the customer data used within the attrition rate determination by agreeing to historical information and underlying accounting records.

| ● | We compared the attrition rate assumptions to actual customer attrition results as part of a retrospective analysis to evaluate the reasonableness of the Company’s attrition rate.

| ● | We utilized an internal valuation specialist to evaluate:

| o | The reasonableness of the selected customer attrition rate by comparing the estimated customer attrition rate used to value the customer relationship intangible asset to historical customer retention data of the acquired entity and that of comparable companies within the industry using publicly available market data, and

| o | The reasonableness of the selected discount rate by comparing the discount rate used to value the customer relationship intangible asset to independently developed discount rates derived from publicly available data for comparable companies.

| ● | We evaluated the reasonableness of the attrition rate and discount rate used by management by analyzing the sensitivity of changes in the attrition rate and discount rate and the resulting impact to the estimated fair values.

​

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.

​

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.

Inventories

Inventories, which consist principally of (i) raw materials and supplies that are consumed providing services to the Company’s customers, (ii) spare parts for equipment used in providing these services and (iii) components and attachments for manufactured equipment used in providing services, are recorded at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (FIFO) method or the weighted average cost method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company regularly reviews inventory quantities on hand and records a write-down for excess or obsolete inventory based primarily on its estimated forecast of product demand, market conditions, production requirements and technological developments.

Property, Plant and Equipment

Property, plant and equipment, including software costs, are reported at cost less accumulated depreciation and amortization, which is provided on a straight-line basis over the estimated useful lives of the assets. Annual depreciation and amortization expenses are computed using the following useful lives: operating equipment, 3 to 20 years; buildings and leasehold improvements, 15 to 39 years or the life of the lease; furniture and fixtures, 5 to 7 years; software, 5 years; and vehicles, 3 to 5 years. The cost of assets retired or otherwise disposed of, and the related accumulated depreciation and amortization are eliminated from the accounts in the year of disposal with the resulting gain or loss credited or charged to income from operations. Expenditures for additions, major renewals, and betterments are capitalized. Expenditures for restoring an identifiable asset to working condition or for maintaining the asset in good working order constitute repairs and maintenance and are expensed as incurred.

RPC records impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. The Company periodically reviews the values assigned to long-lived assets, such as property, plant and equipment, to determine if any impairments should be recognized. There was no impairment recorded during 2025, 2024 or 2023.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of net assets of businesses acquired. The carrying amount of goodwill by reporting segment was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
(in thousands) | Technical Services | ​ ​ ​ | Support Services | ​ | Total
Beginning balance at December 31, 2024 | $ | 49,666 | ​ | $ | 1,158 |  | $ | 50,824

Ending balance at December 31, 2025 | $ | 82,264 | ​ | $ | 1,158 | ​ | $ | 83,422

​

​

Goodwill is reviewed annually, or more frequently, if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount, for impairment. In 2025, the Company performed a quantitative impairment test by estimating the fair value of each of its reporting units by considering both projected discounted future cash flows (an income approach) and comparable public company multiples (a market approach). The discounted cash flow analysis is based on management’s short-term and long-term forecast of operating results for each reporting unit and includes assumptions regarding discount rates, revenue growth rates, expected profitability margins, forecasted capital expenditures, and the timing of expected future cash flows. In 2024, the Company performed a qualitative assessment of its goodwill based on its reporting units’ performance and public market indications of value. Based on these assessments the Company concluded that the fair value of its reporting units exceeded their carrying amounts and therefore no impairment of goodwill occurred during the years ended December 31, 2025, and 2024.

Other intangibles, net

Other intangibles with finite lives include customer relationships, trade names and trademarks and software licenses. These assets are amortized over their legal or estimated useful lives based on methods that approximate the pattern in which the economic benefits are expected to be realized. The amortization periods range from three to 10 years.

Software Licenses

The Company accounts for costs related to internal-use software as follows: (1) hosting arrangement where the Company obtains access to a software license and it is feasible for the Company to take possession and run the software on its own hardware, the Company records an intangible asset and a liability to the extent that all or a portion of the software fees have not been paid, see note to the consolidated financial statements titled “Other intangibles”, net for details of software licenses recorded as part of intangible assets, (2) capitalizes costs related to application development stage after the preliminary project stage is completed and management has authorized and committed to funding the project and it is probable that the project will be completed, and the software will be used to perform as intended, and (3) expenses costs related to arrangements considered software as a service where the Company has access to a vendor managed software that do not meet the criteria for software purchase or license.

Insurance Expense

RPC self-insures certain risks related to general liability, workers’ compensation, vehicle, property, cyber 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.

Income Taxes

Deferred tax liabilities and assets are determined based on the difference between the financial and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance against the carrying value of deferred tax assets when the Company determines that it is more likely than not that the asset will not be realized through future taxable income.

Share Repurchases

The Company records the cost of share repurchases in stockholders’ equity as a reduction to common stock to the extent of par value of the shares acquired and the remainder is allocated to capital in excess of par value and retained earnings if capital in excess of par value is depleted. The Company tracks capital in excess of par value on a cumulative basis for each reporting period and discloses the excess over capital in excess of par value as part of stock purchased and retired in the consolidated statements of stockholders’ equity.

​

Earnings per Share

Basic and diluted earnings per share are computed by dividing net income by the weighted average number of shares outstanding during the respective periods. In addition, the Company has periodically issued share-based payment awards that contain non-forfeitable rights to dividends and are therefore considered participating securities. See note to the consolidated financial statements titled “Employee Benefit Plans” for further information on restricted stock granted to employees.

​

Restricted shares of common stock (participating securities) outstanding and a reconciliation of weighted average shares outstanding is as follows:

Shares used in calculating basic and diluted earnings per share |  | 212,158 | ​ |  | 211,358 | ​ |  | 212,927

​

Fair Value of Financial Instruments

The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, investments, accounts payable, and debt. The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximate their fair value due to the short-term nature of such instruments.

Stock-Based Compensation

Stock-based compensation expense is recognized for all share-based payment awards, net of estimated forfeitures. Accordingly, compensation cost is amortized for those shares expected to vest on a straight-line basis over the requisite service period of the award. See note to the consolidated financial statements titled “Employee Benefit Plans” for additional information.

Advertising

Advertising costs are expensed during the period in which they are incurred. Advertising expenses totaled $3.6 million in 2025, $2.3 million in 2024, and $2.4 million in 2023.

Leases

The Company determines at contract inception if an arrangement is a lease or contains a lease based on whether the Company obtains the right to control the use of specifically identifiable property, plant and equipment for a period of time in exchange for consideration. The Company’s lease population consists primarily of real estate including its corporate headquarters, office space and warehouses, in addition to vehicles, storage containers and office equipment. The Company’s population of month-to-month real estate leases have been classified as short-term leases. The Company has elected not to separate non-lease components from lease components for its leases. Variable lease payments relate primarily to taxes and insurance on real estate contracts and are recognized as expense when incurred.

Note 2: Acquisition

On April 1, 2025 (the "Closing Date”), RPC, through its wholly owned subsidiary, Thru Tubing Solutions, Inc., completed its previously announced acquisition of Pintail Alternative Energy, L.L.C. ("Pintail”). Pursuant to the terms of the Membership Interest Purchase Agreement dated as of April 1, 2025 (the "Merger Agreement”), by and among RPC and Pintail, on the Closing Date, Pintail merged with and into RPC (the "Merger”), and Pintail continued as a wholly owned subsidiary of RPC. Pintail, headquartered in Midland, Texas, is a leading provider of oilfield wireline perforating services in the Permian Basin, and its conventional and electric wireline units are among the newest in the industry. The acquisition is building on RPC’s diversified oilfield services platform with geographic concentration in the most active oil producing region in the U.S. land market. Pintail is included in our Technical Services Segment.

Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, on the Closing Date, 100% of Pintail’s equity was automatically canceled and converted into the right to receive (i) $170 million in cash ("the Closing Cash”), (ii) $25 million of RPC common stock, which was paid by the issuance of 4,545,454 shares of restricted common stock of RPC ("Stock Consideration”) to one of the previous owners (the "Seller”), and (iii) $50 million in the form of a secured note payable to Houston LP (the "Seller Note”). Interest on the Seller Note accrues at a variable rate equal to the Simple Secured Overnight Financing Rate ("SOFR”), for the applicable interest period, plus 2.0% per annum, or where applicable, at a specified default rate.

The Stock Consideration and 50% of the Seller Note (together "Contingent Consideration”) are subject to continued employment of Seller for a period of three years and subject to automatic forfeiture in the event of Seller termination. In accordance with U.S. GAAP, the Contingent Consideration is not accounted for as part of purchase price. As of Closing Date, the Company evaluated the fair value of the Seller Note using a market interest rate based on the Company’s IBR ("Incremental Borrowing Rate”). As the contractual interest rate on the Seller Note (6.0% based on prevailing SOFR) was materially consistent with the estimated market rate, the Seller Note was recorded on the Consolidated Balance Sheet at the estimated present value of $50 million as Notes Payable in the current and non-current section of Total liabilities on the Consolidated Balance Sheet as of December 31, 2025. The Company recognized an acquisition related employment obligation asset for $25 million, related to 50% of the Seller Note, that is part of the Contingent Consideration. This asset is being amortized over the three-year service period on a straight-line basis and reflected as part of Other assets in the current and non-current sections of Total assets on the Consolidated Balance Sheet as of December 31, 2025.

An additional amount totaling $37.5 million, ("Redistribution Payments”) paid by the Seller out of Closing Cash, is subject to continued employment with RPC for a period of three years from the Closing Date. The Stock Consideration and Redistribution

Years ended December 31, 2025, 2024 and 2023

​

Payments are being amortized over the three-year service period and recorded as Acquisition related employment costs and Additional Paid in Capital.

Amortization of non-cash expenses related to the Contingent Consideration and the Redistribution Payments are reflected as Acquisition related employment costs in the Consolidated Statement of Operations. For the period from April 1, 2025, to December 31, 2025, these amounts totaled $20.3 million.

The Company incurred transaction expenses of approximately $1.6 million in 2025, which are included in Selling, general and administrative expenses within the Company’s Consolidated Statements of Operations.

The acquisition was accounted for as a business combination using the acquisition method of accounting in accordance with ASC 805, Business Combinations ("ASC 805”), primarily using Level 3 inputs. The preliminary purchase price allocation disclosed as of September 30, 2025, has been revised as new information was received and analyzed resulting in a $9.2 million increase in Goodwill and decreases in property, plant and equipment of $4.9 million, customer relationships of $3.5 million and trademarks of $800 thousand. Beginning in the fourth quarter of 2025, wireline cables, previously capitalized and depreciated over 18 months, began to be expensed due to a change in their estimated useful lives, resulting in the decrease in property, plant and equipment. The decrease in customer relationships and tradenames is attributable to the $12.3 million net working capital settlement and valuation refinements. The amounts below represent the current preliminary fair value estimates. As additional information becomes available and final analyses and allocations are completed, we may further revise the preliminary acquisition consideration allocation during the remainder of the measurement period, which will not exceed one year from the acquisition date. As of December 31, 2025, adjustments related to property, plant and equipment is the primary area open for finalization. Such revisions or changes may be material and may impact the valuation of other assets.

The purchase price under U.S. GAAP was $181.4 million, which consisted of Closing Cash of $170.0 million and $25.0 million of the Seller Note not contingent on continued service, offset by $13.6 million of contractual adjustments for Pintail’s final net working capital settlement, cash and debt. Amount due from the seller for the final working capital settlement of $12.3 million was collected in full during the fourth quarter of 2025.

The Company assumed finance leases related to trucks and operating leases for vehicles and certain real estate. There were no favorable or unfavorable market terms for the leases.

The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill, which is being amortized over 15 years for income tax purposes but not for financial reporting purposes. Goodwill is attributable to synergies expected to be achieved from the combined operations of the Company and Pintail and the assembled workforce. The accompanying Consolidated Balance Sheet includes the assets and liabilities of Pintail, which have been measured at fair value as of the acquisition date.

The purchase price allocation above excludes the contingent portion of total consideration consisting of $25 million of the Seller Note and $25 million of Stock Consideration.

The following table summarizes the amounts allocated to identifiable intangible assets acquired:

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Preliminary Fair Value | ​ | ​ | Estimated Useful Life

Trade names and trademarks | ​ | 9,300 | ​ | ​ | 10
Intangible assets acquired | $ | 93,000 | ​ | ​ | ​

​

The fair value of customer relationships was estimated using the multi-period excess earnings method. The multi-period excess earnings methodology is an income approach methodology that estimates the projected cash flows of the business attributable to the customer relationships intangible assets, net of charges for the use of other identifiable assets of the business including working capital, fixed assets and other intangible assets. The fair value determination of the customer relationships require management to make significant estimates and assumptions related to future revenues attributable to existing customers, future EBITDA margins and the selection of the customer attrition rate and discount rate. Changes in assumptions concerning future financial results or other underlying assumptions could have a significant impact on the determination of the fair value assigned to customer relationships and the related amortization expense in future periods.

​

The fair value of trade names was estimated using the relief-from-royalty method, which presumes the owner of the asset avoids hypothetical royalty payments that would need to be made for the use of the asset if the asset was not owned.

Pintail recognizes revenue in an amount equal to consideration received for transferred goods or services to customers. In addition, Pintail has elected the right to invoice practical expedient for recognizing revenue related to its performance obligations.

Pintail’s operating results are included in the Consolidated Statements of Operations for the period from Apil 1, 2025 to December 31, 2025. Pintail's revenues were $295.8 million for the period from April 1, 2025, to December 31, 2025. Pintail’s Net income for the period from April 1, 2025, to December 31, 2025, was $12.1 million, using a normalized estimated effective tax rate. Pintail’s Net income includes the impact of the amortization of intangibles totaling $7.0 million, as well as other purchase accounting adjustments, for the period from April 1, 2025, to December 31, 2025. Acquisition related employment costs are recorded at the consolidated level and not allocated to Pintail.

Note 3: Revenues

Accounting Policy

RPC’s contract revenues are generated principally from providing oilfield services. These services are based on mutually agreed upon pricing with the customer prior to the services being delivered and given the nature of the services, do not include the right of return. Pricing for these services is a function of rates based on the nature of the specific job, with consideration for the extent of equipment, labor, and consumables needed for the job. RPC satisfies its performance obligations over time as the services are performed and records revenues accordingly. RPC records revenues based on the transaction price agreed upon with its customers.

Sales tax charged to customers is presented on a net basis within the Consolidated Statements of Operations and therefore excluded from revenues.

Nature of services

RPC provides a broad range of specialized oilfield services to independent and major oil and gas companies engaged in the exploration, production and development of oil and gas properties throughout the United States and in selected international markets. RPC manages its business as either (1) services offered on the well site with equipment and personnel (Technical Services) or (2) services and tools offered off the well site (Support Services). For more detailed information about operating segments, see note to the consolidated financial statements titled “Business Segment and Entity Wide Disclosures.”

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

RPC, Inc. and Subsidiaries

Years ended December 31, 2025, 2024 and 2023

​

RPC contracts with its customers to provide the following services by reportable segment:

Technical Services

| ● | Includes pressure pumping, wireline, downhole tools, coiled tubing, cementing, snubbing, nitrogen, well control and fishing.

Support Services

| ● | Rental tools – RPC rents tools to its customers for use with onshore and offshore oil and gas well drilling, completion and workover activities.

| ● | Other support services include pipe handling and pipe inspection and storage services, and well control training.

Our contracts with customers are generally short-term in nature and consist of a single performance obligation – the provision of oilfield services.

Payment terms

RPC’s contracts with customers state the final terms of the sales, including the description, quantity, and price of each service to be delivered. The Company’s contracts are generally short-term in nature and in most situations, RPC provides services ahead of payment - i.e., RPC has fulfilled the performance obligation prior to submitting a customer invoice. RPC invoices the customer upon completion of the specified services and collection generally occurs between 30 to 60 days after invoicing. As the Company enters into contracts with its customers, it generally expects there to be no significant timing difference between the date the services are provided to the customer (satisfaction of the performance obligation) and the date cash consideration is received. Accordingly, there is no financing component to our arrangements with customers.

Significant judgments

RPC believes the output method is a reasonable measure of progress for the satisfaction of our performance obligations, which are satisfied over time, as it provides a faithful depiction of (1) our performance toward complete satisfaction of the performance obligation under the contract and (2) the value transferred to the customer of the services performed under the contract. RPC has elected the right to invoice practical expedient for recognizing revenue related to its performance obligations.

Disaggregation of revenues

See note to the consolidated financial statements titled “Business Segment and Entity Wide Disclosures” for disaggregation of revenue by operating segment and services offered in each of them and by geographic regions.

​

Trade receivables relate to revenues generated from equipment and services, for which credit is extended based on our evaluation of the customer’s credit worthiness. Unbilled receivables represent revenues earned but not billed to the customer until future dates, usually within one month. Other receivables consist primarily of net amounts receivable from an agent that operates internationally, as well as amounts due from the favorable resolution of state tax audits and rebates due from suppliers. Trade receivables as of December 31, 2023, were $331.4 million.

​

​

Note 6: Current Expected Credit Losses

The Company utilizes an expected credit loss model for valuing its accounts receivable, a financial asset measured at amortized cost. The Company is exposed to credit losses primarily from providing oilfield services. The Company’s expected credit loss allowance for accounts receivable is based on historical collection experience, current and future economic and market conditions and a review of the current status of customers’ account receivable balances. Due to the short-term nature of such receivables, the estimated amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers’ financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible and recoveries of amounts previously written off are recorded when collected.

​

The following table provides a roll-forward of the allowance for credit losses that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected:

The Base Erosion and Profit Shifting framework 2.0 (Pillar Two) released by the Organization for Economic Co-operation and Development introduced a global minimum corporate tax of 15% for companies with global revenues and profits above certain thresholds. The United States has not yet enacted legislation to adopt the provisions of Pillar Two. As of December 31, 2025, certain countries we operate in have enacted legislation related to the global minimum tax rules under Pillar Two. There are no recorded effects for Pillar Two in our 2025 financial statements as we do not estimate a material impact, if any, to our consolidated financial statements. We will continue to monitor the impact as additional countries enact legislation going forward.

As of December 31, 2025, the Company has net operating loss carryforwards recorded related to state income taxes of $31.2 million (gross) that will expire between 2026 and 2045.

The Company’s policy is to record interest and penalties related to income tax matters, as part of income tax expense. There were no accrued interest and penalties as of December 31, 2025, and $2.5 million as of December 31, 2024.

During 2025, the Company recognized an increase in estimated liability for its unrecognized tax positions, which is recorded in other long-term liabilities on the Consolidated Balance Sheet. This liability, if released, would affect our effective rate. A reconciliation of the beginning and ending amount of unrecognized tax positions is as follows:

​

The Company and its subsidiaries are subject to U.S. federal and state and foreign income tax in multiple jurisdictions. In many cases, the estimated liability for uncertain tax positions are related to tax years that remain open and subject to examination by the relevant taxing authorities. In general, the Company’s 2022 through 2024 tax years remain open to examination. Additional years may be open to the extent attributes are being carried forward to an open year.

Note 12: Notes Payable

The Company has a revolving Credit Agreement with Bank of America and four other lenders which provides for a line of credit of up to $100 million, including a $35 million letter of credit sub-facility, and a $35 million swingline sub-facility. 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.

Under the Credit Agreement, when RPC’s trailing four quarter Adjusted EBITDA (as calculated under the Credit Agreement) is equal to or greater than $50 million: (i) the consolidated leverage ratio cannot exceed 2.50:1.00 and (ii) the debt service coverage ratio must be equal to or greater than 2.00:1.00; otherwise, the minimum tangible net worth must be greater than or equal to $400 million. As of both December 31, 2025, and December 31, 2024, the Company was in compliance with these covenants.

Revolving loans under the amended revolving credit facility bear interest at one of the following two rates at the Company’s election:

| ● | Term SOFR; plus, a margin ranging from 1.25% to 2.25%, based on a quarterly consolidated leverage ratio calculation, and an additional SOFR Adjustment ranging from 10 to 30 basis points depending upon maturity length; or

| ● | the Base Rate, which is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) Bank of America’s publicly announced “prime rate,” and (c) the Term SOFR plus 1.00%, or (d) 1.00%; in each case plus a margin that ranges from 0.25% to 1.25% based on a quarterly consolidated leverage ratio calculation.

In addition, the Company pays an annual fee ranging from 0.20% to 0.30%, based on a quarterly consolidated leverage ratio calculation, on the unused portion of the credit facility.

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. During 2025, the Company assumed a Seller Note as part of the Pintail acquisition; see the note to the consolidated financial statements titled “Acquisition” for additional details related to the Seller Note. Interest incurred, which includes interest on the Seller Note, facility fees on the unused portion of the revolving credit facility and the amortization of loan costs, and interest paid on the Seller Note and the credit facility were as follows for the periods indicated:

Note 14: Cash Paid for Common Stock Purchased and Retired

The Company has a stock buyback program to repurchase up to 49,578,125 shares in the open market. As of December 31, 2025, 12,768,870 shares remained available to be repurchased under the current authorizations. The program does not have a preset expiration date. Repurchases of shares of the Company’s common stock may be made from time to time in the open market, by block purchases, in privately negotiated transactions or in such other manner as determined by the Company. The timing of the repurchases and the actual amount repurchased will depend on a variety of factors, including the market price of the Company's shares, general market and economic conditions, and other factors. The stock repurchase program does not obligate the Company to acquire any particular amount of common stock, and it may be suspended or discontinued at any time.

Shares purchased for withholding taxes represent taxes due upon vesting of time-lapse restricted shares granted to employees. Total share repurchases for 2025, 2024 and 2023 year-to-date are detailed below:

Note 15: Fair Value Disclosures

The various inputs used to measure assets at fair value establish a hierarchy that distinguishes between assumptions based on market data (observable inputs) and the Company’s assumptions (unobservable inputs). The hierarchy consists of three broad levels as follows:

| 1. | Level 1 – Quoted market prices in active markets for identical assets or liabilities.

| 2. | Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

| 3. | Level 3 – Unobservable inputs developed using the Company’s estimates and assumptions, which reflect those that market participants would use.

The following table shows investments measured at net asset value as of December 31, 2025, and 2024:

(in thousands) | ​ | ​ | ​ | ​ | ​ | ​
Investments measured at net asset value | ​ | $ | — | ​ | $ | 30,666

​

Prior to their dissolution, trading securities were comprised of the SERP assets, as described in the note titled “Employee Benefit Plans”, and were recorded primarily at their net cash surrender values, calculated using their net asset values which approximates fair value, as provided by the issuing insurance or investment company. The Company’s policy is to recognize transfers between levels at the beginning of quarterly reporting periods. For the year ended December 31, 2025, there were no significant transfers in or out of levels 1, 2 or 3.

The carrying amounts of other financial instruments reported in the balance sheet for current assets and current liabilities approximate their fair values because of the short maturity of these instruments. The Company currently does not use the fair value option to measure any of its existing financial instruments and has not determined whether or not it will elect this option for financial instruments it may acquire in the future.

​

Note 16: Commitments and Contingencies

Income Taxes - The amount of income taxes the Company pays is subject to ongoing audits by federal and state tax authorities, which often result in proposed assessments. Other long-term liabilities included the Company’s estimated liabilities for probable assessments and totaled $552 thousand as of December 31, 2025, compared to $531 thousand as of December 31, 2024. See note to the consolidated financial statements titled “Income Taxes” for further information related to those liabilities.

Sales and Use Taxes - The Company has ongoing sales and use tax audits in various jurisdictions and may be subjected to varying interpretations of statute that could result in unfavorable outcomes. In accordance with ASC 450-20, Loss Contingencies, any probable and reasonable estimate of assessment costs have been included in accrued state, local and other taxes.

The Company had previously received state tax notifications related to sales and use tax which were resolved subsequent to year-end with no material impact on its consolidated financial position, results of operations or cash flows.

Litigation - 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.

Note 17: Employee Benefit Plans

Supplemental Executive Retirement Plan (SERP)

The Company operated a non-qualified SERP that permitted certain highly compensated employees to defer a portion of their compensation. In the fourth quarter of 2025, the Company completed the dissolution of its SERP and distributed participant balances in full. As part of the dissolution, the Company dissolved the Rabbi Trust and liquidated all the Company-Owned Life Insurance Policies (“COLI”) and other securities held in the Trust. Termination of the SERP was approved by the Board of Directors in the fourth quarter of 2024. Pursuant to the Internal Revenue Service rules, participant balances are required to be distributed between 12 and 24 months after termination. Retirement Plan assets and liabilities were classified as long-term on the Consolidated Balance Sheet as of December 31, 2024, and were reclassified to short-term as of June 30, 2025, when the decision to liquidate the assets and distribute participant balances in the fourth quarter of 2025 was made.

The liquidation of COLI assets resulted in a taxable gain of approximately $18 million that has been included in the income tax provision for the year ended December 31, 2025. The gain resulted from the excess of cash surrender value over the cost basis of the variable life insurance policies held inside the COLI. See note to the consolidated financial statements titled “Income Taxes” for a discussion of the tax impact attributable to the dissolution. Prior to their liquidation, the COLI policies were recorded at their net cash surrender values, which approximated fair value. Proceeds of $33.1 million from dissolution of the assets held inside the Rabbi Trust and participant distributions of $24.5 million are disclosed as Proceeds from benefit plan financing arrangement and Distribution from financing plan arrangement on the Consolidated Statements of Cashflow for the year ended December 31, 2025.

Prior to their dissolution, the SERP assets were classified as trading securities and changes in the fair value of these assets, and normal insurance expenses were recorded in the Consolidated Statements of Operations as compensation cost within selling, general and administrative expenses. Trading gains related to the SERP assets totaled $2.3 million in 2025, $2.7 million in 2024, and $2.6 million in 2023. Any change in the fair value of participant balances was recorded as compensation cost within selling, general and administrative expenses in the Consolidated Statements of Operations, and totaled $2.3 million in 2025, $2.6 million in 2024, and $2.8 million in 2023.

401(k) Plan

RPC sponsors a defined contribution 401(k) Plan that is available to substantially all full-time employees with more than three months of service. Effective January 1, 2019, the Company began matching 100% of employee contributions for each dollar of a participant’s contribution to the 401(k) Plan for the first three percent of his or her annual compensation, and 50% for each dollar of a participant’s contribution to the 401(k) Plan for the next three percent of his or her annual compensation. Employees vest in the Company’s contributions after two years of service. Employees vest in the RPC contributions after two years of service. The charges to expense for the Company’s contributions to the 401(k) Plan were $11.9 million in 2025, $11.6 million in 2024, and $11.3 million in 2023.

Stock Incentive Plans

The Company has issued various forms of stock-based incentives, including incentive and non-qualified stock options, time-lapse restricted shares and performance share unit awards under its Stock Incentive Plans to officers, selected employees and non-employee directors. In April 2025, the Company reserved 8,000,000 shares of common stock under the 2025 Stock Incentive Plan with a term of 10 years expiring in April 2034. As of December 31, 2025, there were 5,746,631 shares available for grant under the Company’s 2025 Stock Incentive Plan (SIP).

The Company recognizes compensation expense for the unvested portion of awards outstanding over the remainder of the service period. The compensation cost recorded for these awards is based on their fair value at the grant date, less the cost of estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods to reflect actual forfeitures.

Pre-tax stock-based employee compensation expense included as part of selling, general and administrative expense was $12.5 million in 2025 ($7.1 million after tax), $9.2 million in 2024 ($7.4 million after tax) and $7.9 million in 2023 ($6.1 million after tax).

​

Restricted Stock

The Company grants certain employees and non-employee directors time-lapse restricted stock which vests after a stipulated number of years from the grant date in the case of employees and vests immediately for non-employee directors, depending on the terms of the issue. Time-lapse restricted shares granted to employees in 2025 and 2024 vest ratably over a period of three years and shares granted to employees in 2023 vest ratably over a period of four years. Grantees receive dividends declared and retain voting rights for the granted shares. The agreement under which the restricted stock is issued provides that shares awarded may not be sold or otherwise transferred until restrictions established under the stock plans have lapsed. Upon termination of employment from the Company, with the exception of death (fully vests) or normal retirement/disability (partially vests based on pre-approved formula), shares with restrictions are forfeited in accordance with the SIP.

In addition to time-lapse restricted stock, officers and selected employees are granted Performance Share Unit (PSU) awards that vest at different levels based on pre-established financial performance targets with a modifier for stock performance based on total shareholder return (TSR). The Company periodically evaluates the portion of performance share unit awards that are probable to vest and updates compensation expense accruals accordingly. The PSUs typically cliff-vest at the end of a three-year performance period. Upon termination of employment (other than due to death or disability as defined in the agreements), the unvested PSUs will be forfeited. In the event of death or disability as defined in the agreements, all unvested PSUs shall vest immediately at 100% of target levels, without regard to the actual EBITDA performance, and with no adjustment for the TSR modifier. PSU awards also include the right to dividend equivalents with respect to the underlying shares which are accrued over the performance period, based upon target payout level and paid out in cash upon vesting of the PSUs. To the extent the awards fail to vest or are forfeited, or the performance goals are not met, no such dividend equivalents will be payable. PSUs confer no voting rights with respect to the underlying shares prior to vesting and payout.

The following is a summary of the changes in non-vested restricted shares for the year ended December 31, 2025:

Note 18: Related Party Transactions

Marine Products Corporation

In conjunction with RPC’s spin-off of its powerboat manufacturing business, RPC and Marine Products entered into various agreements that define the companies’ relationship. Per the terms of their Transition Support Services agreement, which may be terminated by either party, RPC provides certain administrative services, including financial reporting and income tax administration, acquisition assistance, etc., to Marine Products. Charges from the Company (or from corporations that are subsidiaries of the Company) for such services were $1.1 million in 2025, $1.1 million in 2024, and $1.0 million in 2023. The Company’s receivable due from Marine Products for these services was $58 thousand as of December 31, 2025, and $99 thousand as of December 31, 2024. All of the Company’s directors are also directors of Marine Products, and the executive officers are employees of both the Company and Marine Products.

On February 5, 2026, Marine Products entered into an Agreement and Plan of Merger with MasterCraft Boat Holdings, Inc., a Delaware corporation (“MasterCraft”). The transaction is subject to shareholder and regulatory approvals and other closing conditions. If the Proposed Merger closes as planned, the Transition Support Services agreement is expected to be canceled on or about the closing date and a new Transition Support Services agreement is expected to be signed with Mastercraft.

Other

The Company periodically purchases, in the ordinary course of business, products or services from suppliers that are owned by officers or significant stockholders of or affiliated with certain directors of RPC. The total amounts paid to these affiliated parties were $60 thousand in 2025, $1.6 million in 2024 and $1.8 million in 2023. All of the related party transactions are reviewed and approved by a subcommittee of the Nominating and Corporate Governance Committee consisting of independent members.

A group that includes Amy R. Kreisler and Timothy C. Rollins, each of whom is a director of the Company, certain of their family members, and certain companies under their and/or their family members’ control, controls in excess of fifty percent of the Company’s voting power.

RPC and Marine Products own 50% each of a limited liability company called 255 RC, LLC that was created for the joint purchase and ownership of a corporate aircraft. The purchase of the aircraft was completed in January 2015, and the purchase was funded primarily by a $2,554,000 contribution by each company to 255 RC, LLC. Each of RPC and Marine Products is currently a party to an operating lease agreement with 255 RC, LLC for a period of five years. RPC recorded certain net operating costs comprised of rent and an allocable share of fixed costs of approximately $180 thousand in 2025, $230 thousand in 2024 and $200 thousand in 2023 for the corporate aircraft. The Company had a payable to 255 RC, LLC of $2.2 million as of December 31, 2025, and $2.0 million as of December 31, 2024. The Company accounts for this investment using the equity method and its proportionate share of income or loss is recorded in selling, general and administrative expenses. As of December 31, 2025, the investment closely approximates the underlying equity in the net assets of 255 RC, LLC and the undistributed earnings represented in retained earnings were approximately $4.3 million. There are no immediate changes expected in this arrangement as a result of the merger which may be subject to change in the future.

Pursuant to the registration rights agreement between us and our largest stockholder, LOR, Inc. (LOR) and certain of its affiliates (collectively, the Selling Stockholders) and their permitted transferees, we have filed a shelf registration statement on Form S-3 with the SEC that expires on May 5, 2028. The Form S-3 shelf registration statement registers for the resale of up to 127,235,202 shares of our common stock, which represents a majority of the Company securities held by the Selling Stockholders. In addition, they have the right to require, subject to certain conditions and limitations, certain piggyback registration rights with respect to registrations initiated by us.

Note 19: Business Segment and Entity Wide Disclosures

RPC’s reportable segments are the same as its operating segments. RPC manages its business under Technical Services and Support Services. Technical Services is comprised of service lines that generate revenue based on equipment, personnel or materials at the well site and are closely aligned with completion and production activities of the customers. Support Services is comprised of service lines which generate revenue from services and equipment offered off the well site and are closely aligned with the customers’ drilling activities. Selected overhead including centralized support services and regulatory compliance are classified as Corporate.

Technical Services consists primarily of pressure pumping, downhole tools, coiled tubing, cementing, snubbing, nitrogen, well control, wireline and fishing. The services offered under Technical Services are high capital and personnel intensive businesses. The Company considers all of these services to be closely integrated oil and gas well servicing businesses and makes resource allocation and performance assessment decisions based on this operating segment as a whole across these various services.

Support Services consist primarily of drill pipe and related tools, pipe handling, pipe inspection and storage services, and oilfield training services. The demand for these services tends to be influenced primarily by customer drilling-related activity levels.

The Company’s Chief Operating Decision Maker (CODM) assesses performance and makes resource allocation decisions regarding, among others, staffing, growth and maintenance capital expenditures and key initiatives based on the operating segments outlined above.

The accounting policies of the reportable segments are the same as those described in the note titled “Significant Accounting Policies.” Gains or losses on disposition of assets are reviewed on a consolidated basis, and accordingly the Company does not report gains or losses at the segment level. Intersegment revenues are generally recorded in segment operating results at prices that management believes approximate prices for arm’s length transactions and are not material to operating results.

RPC's CODM is its Chief Executive Officer. For each of the reportable segments, the CODM uses operating income to allocate resources (equipment, financial, and human resources).

Significant segment expense by reportable segment for the years ended December 31, 2025, 2024 and 2023 are shown in the following tables:

Note 20: Leases

The Company recognizes operating and finance leases with a duration greater than 12 months on the Consolidated Balance Sheet with a Right-Of-Use (ROU) asset and liability at the present value of lease payments over the term. Leases that include rental escalation clauses or renewal options are factored into the determination of lease payments when appropriate. There are no residual value guarantees on the existing leases. The Company estimates its incremental borrowing rate at lease commencement to determine the present value of lease payments, since most of the Company’s leases do not provide an implicit rate of return. ROU assets exclude lessor incentives received.

The Company subleases certain real estate to third parties. Our sublease portfolio consists solely of operating leases. As of December 31, 2025, the Company had no operating or finance leases that had not yet commenced. During the year ended December 31, 2025, the Company assumed certain leases as part of its acquisition of Pintail. The disclosures below include information related to the leases after the acquisition. See note to the consolidated financial statements titled “Acquisition” for further information related to those leases.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

​

Item 9A. Controls and Procedures

Evaluation of disclosure controls and procedures — The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and that such information is accumulated and communicated to its management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As of the end of the period covered by this report, December 31, 2025 (the Evaluation Date), the Company carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures. Based upon this evaluation, which excluded the impact of the acquisition of Pintail, discussed below, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective at a reasonable assurance level as of the Evaluation Date.

As discussed in the Note titled “Acquisition” of the Notes to Consolidated Financial Statements. “Financial Statements” of this Form 10-K for the year ended December 31, 2025, we completed the acquisition of Pintail during the second quarter. As part of our post-closing integration activities, we have been engaged in the process of assessing the internal controls of Pintail and are continuing to integrate policies, processes, people, technology, and operations for the post-acquisition combined company. As permitted for newly acquired businesses by interpretive guidance issued by the staff of the SEC, management has excluded the internal control over financial reporting of Pintail from the evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2025. We have reported the operating results of Pintail in our Consolidated Statements of Operations and Statements of Cash Flows from the acquisition date through December 31, 2025. As of December 31, 2025, total assets related to Pintail represented approximately 17% of our total assets, recorded on a preliminary basis as the measurement period for the business combination remained open as of December 31, 2025. Revenues from Pintail represented approximately 18% of our total consolidated revenues for the year ended December 31, 2025.

Management’s Report on Internal Control over Financial Reporting — Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Management’s Report on Internal Control over Financial Reporting is included on page 35 of this report. Grant Thornton LLP, the Company’s independent registered public accounting firm, has audited the effectiveness of internal control as of December 31, 2025, and issued a report thereon which is included on page 36 of this report.

Changes in internal control over financial reporting — The Company has successfully completed the mapping of Pintail’s accounts to our existing financial reporting systems. The Company is continuing to review key controls and has implemented controls related to all Pintail financial statement line items and consolidation in order to enable the accurate preparation and timely reporting of their results.

​

Other than the changes to Pintail controls noted above, there were no changes in the Company’s internal control over financial reporting during 2025 which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

​

Item 9B. Other Information
