districts. Cudd Energy Services’ pumping and Pintail Completions’ wireline declined 6% and 3%, respectively, partially offset by Cudd Pressure Control’s snubbing revenues, which grew by 13%. Our Support Services segment revenues declined 18% sequentially, primarily due to Patterson Services’ rental tools declining 22% during the quarter as several jobs shifted into early 2026,” stated Ben M. Palmer, RPC’s President and Chief Executive Officer. “As we enter 2026, we are focused on disciplined execution, leveraging our strong brands and diversified offerings.”

“We experienced a solid start to the fourth quarter but encountered a weak December as a number of our customers reduced activity, particularly late in the month. The macro environment remains challenging, with crude oil prices showing increased volatility due to recent geopolitical developments. As we look ahead, our focus remains on delivering full cycle returns by maintaining cost discipline, deploying capital strategically, and positioning the company for long-term success.”

4Q:25 Consolidated Financial Results (sequential comparisons to previous quarter)

Revenues were $425.8 million, down 5%. Within the Technical Services segment, we saw revenues decrease 4% sequentially with snubbing and cementing showing sequential growth offset by declines in our other service lines. Within the Support Services segment we saw an 18% sequential decrease with rental tools showing a sequential decrease of 22%, slightly offset by increases in tubular services.

Cost of revenues, which excludes depreciation and amortization of $33.8 million, was $336.6 million, up slightly from $334.7 million. Despite lower revenues, the cost of revenues increased during the quarter due to expensing year-to-date wireline cable purchases of approximately $12 million that were previously being capitalized, and increases in other materials and supplies expenses related to job mix.

Selling, general and administrative expenses were $47.7 million, up from $44.6 million, primarily related to employment incentives and higher other employment related costs.

Acquisition related employment costs were approximately $7.3 million during 4Q:25 and represent non-cash accounting adjustments related to the Pintail acquisition costs that are contingent upon continued employment.

Interest income totaled $1.7 million, approximating the prior quarter.

Interest expense totaled $942 thousand, approximating the prior quarter.

Income tax provision was $3.2 million, with an unusually high effective tax rate primarily due to the liquidation of company-owned life insurance policies that were part of the previously announced dissolution of the company’s non-qualified supplemental retirement plan, coupled with the non-deductible portion of Acquisition related employment costs.

Net loss and Loss per share were a loss of $3.1 million and $0.02 respectively, versus net income of $13.0 million and diluted earnings per share of $0.06, respectively, in 3Q:25. Net income margin decreased 360 basis points sequentially to (0.7)%.

Segment Operations (sequential comparisons versus the previous quarter)

Technical Services performs value-added completion, production and maintenance services directly to a customer’s well. These services include pressure pumping, downhole tools, wireline, coiled tubing, cementing, and other offerings.

Revenues were $405.2 million, down 4%

Operating income was $8.5 million, down 65%

Operating income was negatively impacted by approximately $8 million due to the transition to expensing wireline cables during the quarter. See Appendix A for additional details

Support Services provides equipment for customer use or services to assist customer operations, including rental tools, pipe inspection services and storage.

Revenues were $20.5 million, down 18%

Operating income was $1.7 million, down 63%

Lower revenues were driven by decreased activity in rental tools, particularly in December

⁽¹⁾ Beginning in the fourth quarter of 2025, wireline cables, previously capitalized and depreciated over 18 months, are now being expensed due to a change in their estimated useful lives. Wireline cable adjustments year-to-date totaled approximately $13.8 million: $4.7 million in second quarter, $4.5 million in the third quarter, and $4.6 million in the fourth quarter. Wireline cable purchase expenses are offset by a decrease in depreciation of $1.9 million in the second quarter, $2.5 million in the third quarter and $1.0 million in the fourth quarter. The net year-to-date operating income impact was additional expense of $8.3 million comprised of $2.8 million in the second quarter, $2.0 million in the third quarter and $3.5 million in the third quarter.

Non-GAAP Measures

RPC, Inc. has used the non-GAAP financial measures of adjusted revenues, adjusted operating income, adjusted net income, adjusted net income margin, adjusted earnings per share, adjusted EBITDA, adjusted EBITDA margin and free cash flow in today's earnings release. These measures should not be considered in isolation or as a substitute for performance or liquidity measures prepared in accordance with GAAP. Management believes that presenting these non-GAAP measures, other than free cash flow, enables investors to compare the operating performance of our core business consistently over various time periods, and in the case of Adjusted EBITDA, without regard to changes in our capital structure or changes in our accounting for purchases of wireline cables. Management believes that free cash flow, which measures our ability to generate additional cash from our business operations, is an important financial measure for use in evaluating RPC's liquidity. Free cash flow should be considered in addition to, rather than as a substitute for, net cash provided by operating activities as a measure of our liquidity. Additionally, RPC’s definition of free cash flow is limited, in that it does not represent residual cash flows available for discretionary expenditures, due to the fact that the measure does not deduct the payments required for debt service and other contractual obligations or payments made for business acquisitions. Therefore, management believes it is important to view free cash flow as a measure that provides supplemental information to our Condensed Consolidated Statements of Cash Flows.

Page 9

Fourth Quarter 2025 Earnings Release

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 statement 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.

Set forth in the appendices below are reconciliations of these non-GAAP measures with their most directly comparable GAAP measures. These reconciliations also appear on RPC, Inc.'s investor website, which can be found at www.rpc.net.
