RECENT ACCOUNTING STANDARDS
RECENT ACCOUNTING STANDARDS	Recently Issued Accounting Standards Not Yet Adopted: ​ ● ASU No. 2020-04 — Reference Rate Reform (Topic 848): The amendments in this ASU, provides optional guidance for a limited time to ease the impact of the reference rate reform on financial reporting. The amendments, which are elective, provide expedients to contract modifications, affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or other reference rate that is expected to be discontinued due to reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022 and may be applied to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company plans to adopt these provisions when LIBOR is discontinued (currently expected to be in July 2022) and does not expect adoption to have a material impact on its consolidated financial statements. ​ ● ASU No. 2021-08: Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers: The amendments in this ASU address diversity in practice related to the accounting for revenue contracts with customers acquired in a business combination, by adopting guidance requiring an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer would recognize and measure the acquired contract assets and contract liabilities in the same manner that they were recognized and measured in the acquiree's financial statements before the acquisition. The company plans to adopt these provisions prospectively to business combinations occurring after January 1, 2023 and does not expect adoption to have a material impact on its consolidated financial statements . ​

REVENUES

REVENUES.
REVENUES	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 typically satisfies its performance obligations over time as the services are performed. 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 6. RPC contracts with its customers to provide the following services by reportable segment: Technical Services ● Support Services ● ● Our contracts with customers are generally very short-term in nature and generally 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 is generally expected 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 6 for disaggregation of revenue by operating segment and services offered in each of them and by geographic regions. Timing of revenue recognition for each of the periods presented is shown below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ March 31, ​ (in thousands) 2022 2021 ​ Oilfield services transferred at a point in time ​ $ — ​ $ — ​ Oilfield services transferred over time ​ ​ 284,624 ​ 182,610 ​ Total revenues ​ $ 284,624 ​ $ 182,610 ​ ​ Contract balances: Contract assets representing the Company’s rights to consideration for work completed but not billed are included in accounts receivable, net on the consolidated balance sheets are shown below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, (in thousands) 2022 2021 Unbilled trade receivables ​ $ 70,061 ​ $ 50,370 ​ Substantially all of the unbilled trade receivables disclosed were or are expected to be invoiced during the following quarter.

BUSINESS SEGMENT INFORMATION
BUSINESS SEGMENT INFORMATION	6. BUSINESS SEGMENT INFORMATION 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 tools offered off the well site and are more closely aligned with the customers’ drilling activities. Selected overhead including certain centralized support services and regulatory compliance are classified as Corporate. Technical Services consists primarily of pressure pumping, downhole tools, coiled tubing, 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 and consulting 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. Segment Revenues: RPC’s operating segment revenues by major service lines are shown in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ March 31, ​ (in thousands) 2022 2021 ​ Technical Services: ​ ​ ​ ​ ​ Pressure Pumping ​ $ 119,898 ​ $ 74,900 ​ Downhole Tools ​ ​ 81,070 ​ 56,377 ​ Coiled Tubing ​ ​ 26,850 ​ 14,768 ​ Nitrogen ​ ​ 7,603 ​ 11,160 ​ Snubbing ​ ​ 6,212 ​ 3,832 ​ All other ​ ​ 24,716 ​ 11,604 ​ Total Technical Services ​ $ 266,349 ​ $ 172,641 ​ ​ ​ ​ ​ ​ ​ ​ ​ Support Services: ​ ​ ​ Rental Tools ​ $ 13,063 ​ $ 6,032 ​ All other ​ 5,212 ​ 3,937 ​ Total Support Services ​ $ 18,275 ​ $ 9,969 ​ ​ ​ ​ ​ ​ ​ ​ ​ Total revenues ​ $ 284,624 ​ $ 182,610 ​ ​ The following summarizes revenues for the United States and separately for all international locations combined for the three months ended March 31, 2022 and 2021. The revenues are presented based on the location of the use of the equipment or services.

RPC evaluates the performance of its segments based on revenues, operating profits and return on invested capital. Gains or losses on disposition of assets are reviewed by the CODM on a consolidated basis, and accordingly the Company does not report gains or losses at the segment level. Inter-segment 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. Summarized financial information with respect RPC’s reportable segments for the three months ended March 31, 2022 and 2021 are shown in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ March 31, (in thousands) 2022 2021 Revenues: ​ ​ Technical Services ​ $ 266,349 ​ $ 172,641 Support Services ​ 18,275 ​ 9,969 Total revenues ​ $ 284,624 ​ $ 182,610 Operating income (loss): ​ ​ ​ ​ Technical Services ​ $ 21,811 ​ $ (5,762) Support Services ​ 2,780 ​ (2,896) Corporate Expenses ​ (4,510) ​ (3,323) Gain on disposition of assets, net ​ 2,954 ​ 1,460 Total operating income (loss) ​ $ 23,035 ​ $ (10,521) Interest expense ​ (178) ​ (380) Interest income ​ 15 ​ 18 Other income, net ​ 504 ​ 507 Income (loss) before income taxes ​ $ 23,376 ​ $ (10,376) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of and for the three months ended ​ Technical ​ Support ​ ​ ​ ​ ​ ​ March 31, 2022 Services Services Corporate Total (in thousands) ​ ​ ​ ​ Depreciation and amortization ​ $ 16,974 ​ $ 2,427 ​ $ 65 ​ $ 19,466 Capital expenditures ​ 16,624 ​ 2,410 ​ 50 ​ 19,084 Identifiable assets ​ $ 616,961 ​ $ 74,021 ​ $ 200,186 ​ $ 891,168 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of and for the three months ended ​ Technical ​ Support ​ ​ ​ ​ ​ ​ March 31, 2021 Services Services Corporate Total (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Depreciation and amortization ​ $ 15,728 ​ $ 1,977 ​ $ 68 ​ $ 17,773 Capital expenditures ​ 9,648 ​ 1,937 ​ 165 ​ 11,750 Identifiable assets ​ $ 507,815 ​ $ 70,304 ​ $ 221,954 ​ $ 800,073 ​

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. Estimates used to determine the allowance for current expected credit losses are based on an assessment of anticipated payment and all other historical, current and future information that is reasonably available. 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: ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, 2022 2021 (in thousands) ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 6,765 ​ $ 4,815 Provision for current expected credit losses ​ ​ 1,131 ​ 946 Write-offs ​ ​ (1,708) ​ (53) Recoveries collected (net of expenses) ​ ​ 2 ​ 9 Ending balance ​ $ 6,190 ​ $ 5,717 ​

COMMITMENTS AND CONTINGENCIES 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 has received a state tax notification of audit results related to sales and use tax and with its outside legal counsel has evaluated the perceived merits of this tax assessment. The Company believes the likelihood of a material loss related to this contingency is remote and cannot be reasonably estimated at this time. Therefore, no loss has been recorded and the Company currently does not believe the resolution of this claim will have a material impact on its consolidated financial position, results of operations or cash flows. ​

The Company currently expects to make a final cash contribution of approximately million as part of the termination. As of the plan termination date, the Company will recognize a pre-tax, non-cash settlement charge representing the unamortized net loss in the plan which was approximately in the plan. For the year ending December 31, 2022, the Company has utilized an expected return on plan assets of ​ The Company did not make a cash contribution to this plan during the three months ended March 31, 2022 or March 31, 2021. ​ The Company permits selected highly compensated employees to defer a portion of their compensation into the non-qualified Supplemental Retirement Plan (“SERP”). The Company maintains certain securities primarily in mutual funds and company-owned life insurance (“COLI”) policies as a funding source to satisfy the obligation of the SERP that have been classified as trading, and are stated at fair value totaling $30.2 million as of March 31, 2022 and $31.7 million as of December 31, 2021. Trading losses related to the SERP assets totaled approximately $1.5 million during the three months ended March 31, 2022, compared to trading gains of approximately $471 thousand during the three months ended March 31, 2021. The SERP assets are reported in non-current other assets on the consolidated balance sheets and changes in the fair value of these assets are reported in the consolidated statements of operations as compensation cost in selling, general and administrative expenses. ​ The SERP liabilities includes participant deferrals net of distributions and are stated at fair value of approximately $26.6 million as of March 31, 2022 and $29.7 million as of December 31, 2021. The SERP liabilities are reported on the consolidated balance sheets in long-term pension liabilities and any change in the fair value is recorded as compensation cost within selling, general and administrative expenses in the consolidated statements of operations. Changes in the fair value of the SERP liabilities represented unrealized losses of approximately $1.4 million during the three months ended March 31, 2022, compared to unrealized gains of approximately $586 thousand during the three months ended March 31, 2021.

NOTES PAYABLE TO BANKS
NOTES PAYABLE TO BANKS	11. NOTES PAYABLE TO BANKS 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 subfacility, and a $35 million swingline subfacility. 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 percent 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 July 26, 2023. During the third quarter of 2020, the Company entered into Amendment No. 5 to Credit Agreement (the “Amendment”). This Amendment (1) reduced the maximum amount available for borrowing under the credit facility from $125 million to $100 million, (2) decreased the minimum tangible net worth covenant level from not less than $600 million to not less than $400 million, and (3) increased the margin spreads and commitment fees payable by RPC by 37.5 and 5 basis points, respectively, at each pricing level of the applicable rate without any changes to the leverage ratios used to calculate such spreads. The Credit Agreement includes the following covenants: (i) when RPC’s trailing four quarter EBITDA (as calculated under the Credit Agreement) is equal to or greater than $50 million, a maximum consolidated leverage ratio of 2.50:1.00 and a minimum debt service coverage ratio of 2.00:1.00, and (ii) when RPC’s trailing four quarter EBITDA is less than $50 million, a minimum tangible net worth of no less than $400 million. As of March 31, 2022, 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: ● the Eurodollar Rate, which is the rate per annum equal to the London Interbank Offering Rate (“LIBOR”); plus, a margin ranging from 1.5 % to 2.5 %, based on a quarterly consolidated leverage ratio calculation; 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 Eurodollar Rate plus 1.00 %; in each case plus a margin that ranges from 0.5 % to 1.5 % 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. The Company has incurred total loan origination fees and other debt related costs associated with this revolving credit facility in the aggregate of approximately $3.4 million. These costs are being amortized to interest expense over the remaining term of the loan, and the remaining unamortized balance of $0.2 million at March 31, 2022 is classified as part of non-current other assets. As of March 31, 2022, RPC had no outstanding borrowings under the revolving credit facility, and letters of credit outstanding relating to self-insurance programs and contract bids totaled $16.3 million; therefore, a total of $83.7 million of the facility was available. Interest incurred, which includes facility fees on the unused portion of the revolving credit facility and the amortization of loan costs, and interest paid on the credit facility were as follows for the periods indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ ​ March 31, (in thousands) 2022 2021 Years Ended December 31, ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ ​ ​ ​ Interest incurred ​ $ 65 ​ $ 41 Interest paid ​ ​ 43 ​ ​ 42 ​ ​

FAIR VALUE DISCLOSURES
FAIR VALUE DISCLOSURES	13. 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. 2. 3. The following table summarizes the valuation of financial instruments measured at fair value on a recurring basis in the balance sheets as of March 31, 2022 and December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at March 31, 2022 with: ​ ​ ​ ​ Quoted prices in ​ Significant ​ ​ ​ ​ ​ ​ active markets ​ other ​ Significant ​ ​ ​ ​ for identical ​ observable ​ unobservable (in thousands) Total assets inputs inputs ​ ​ ​ (Level 1) ​ (Level 2) ​ (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity securities ​ $ 228 ​ $ 228 ​ $ — ​ $ — Investments measured at net asset value ​ $ 30,194 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2021 with: ​ ​ ​ ​ Quoted prices in ​ Significant ​ ​ ​ ​ ​ ​ active markets ​ other ​ Significant ​ ​ ​ ​ for identical ​ observable ​ unobservable (in thousands) Total assets inputs inputs ​ (Level 1) (Level 2) (Level 3) Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity securities ​ $ 197 ​ $ 197 ​ $ — ​ $ — Investments measured at net asset value ​ $ 31,738 ​ ​ ​ ​ The Company determines the fair value of equity securities that have a readily determinable fair value through quoted market prices. The total fair value is the final closing price, as defined by the exchange in which the asset is actively traded, on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs. Marketable securities comprised of the SERP assets, are 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. Significant observable inputs, in addition to quoted market prices, were used to value the trading securities. The Company’s policy is to recognize transfers between levels at the beginning of quarterly reporting periods. For the quarter ended March 31, 2022, there were no significant transfers in or out of levels 1, 2 or 3. Under the Company’s revolving credit facility, there was no balance outstanding at March 31, 2022 and December 31, 2021. Borrowings under our revolving credit facility are typically based on the quote from the lender (level 2 inputs), which approximates fair value, and bear variable interest rates as described in Note 11. The Company is subject to interest rate risk, to the extent there are outstanding borrowings on the variable component of the interest rate. 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 it will elect this option for financial instruments acquired in the future. The Company’s real estate classified as held for sale has been stated at fair value less costs. The fair value measurement was based on observable market data that includes estimated values per square foot involving comparable properties in similar locations. The non-recurring fair value measurement of both these asset categories are reflected in the table below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at March 31, 2022 with: ​ ​ ​ ​ ​ Quoted prices in ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ active markets ​ other ​ Significant ​ ​ ​ ​ ​ for identical ​ observable ​ unobservable (in thousands) Total assets inputs inputs ​ ​ ​ ​ ​ (Level 1) ​ (Level 2) ​ (Level 3) Assets: ​ ​ ​ ​ Assets held for sale ​ $ 692 ​ $ — ​ $ 692 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2021 with: ​ ​ ​ Quoted prices Significant ​ ​ ​ ​ ​ ​ ​ active ​ other ​ Significant ​ ​ ​ ​ ​ for ​ observable ​ unobservable (in thousands) ​ Total ​ assets ​ inputs ​ inputs ​ ​ ​ ​ ​ (Level 1) ​ (Level 2) ​ (Level 3) Assets: ​ ​ ​ ​ Assets held for sale ​ $ 4,032 ​ $ — ​ $ 4,032 ​ $ — ​

Recently Issued Accounting Standards Not Yet Adopted	Recently Issued Accounting Standards Not Yet Adopted: ​ ● ASU No. 2020-04 — Reference Rate Reform (Topic 848): The amendments in this ASU, provides optional guidance for a limited time to ease the impact of the reference rate reform on financial reporting. The amendments, which are elective, provide expedients to contract modifications, affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or other reference rate that is expected to be discontinued due to reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022 and may be applied to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company plans to adopt these provisions when LIBOR is discontinued (currently expected to be in July 2022) and does not expect adoption to have a material impact on its consolidated financial statements. ​ ● ASU No. 2021-08: Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers: The amendments in this ASU address diversity in practice related to the accounting for revenue contracts with customers acquired in a business combination, by adopting guidance requiring an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer would recognize and measure the acquired contract assets and contract liabilities in the same manner that they were recognized and measured in the acquiree's financial statements before the acquisition. The company plans to adopt these provisions prospectively to business combinations occurring after January 1, 2023 and does not expect adoption to have a material impact on its consolidated financial statements .
Revenues	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 typically satisfies its performance obligations over time as the services are performed. 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.
