## Exhibit 99.1

First Quarter 2026 Earnings Release

**Exhibit 99.1**

![Graphic](res-20260507xex99d1001.jpg)

**RPC, Inc. Reports First Quarter 2026 Financial Results** 

ATLANTA, May 7, 2026 - RPC, Inc. (NYSE: RES) ("RPC" or the "Company"), a leading diversified oilfield services company, announced its unaudited results for the first quarter ended March 31, 2026.

***Non-GAAP and adjusted measures*** *may include, adjusted operating income, adjusted net income, adjusted net income margin, adjusted earnings per share (diluted), EBITDA and adjusted EBITDA, adjusted EBITDA margin, and free cash flow which are reconciled to the most directly comparable GAAP measures in the appendices of this earnings release.*

***Sequential comparisons*** *are to 4Q:25. The Company believes quarterly sequential comparisons are most useful in assessing industry trends and RPC's recent financial results. Both sequential and year-over-year comparisons are available in the tables at the end of this earnings release.*

**First Quarter 2026 Highlights**

● Revenues increased 7% sequentially to $454.8 million

● Net income was $0.9 million, compared to net loss of $3.1 million in the prior quarter, and diluted Earnings Per Share (EPS) was $0.00; Net income margin increased 90 basis points sequentially to 0.2%

● Adjusted net income was $7.6 million, compared to $9.4 million in the prior quarter, and adjusted diluted EPS was $0.03; Adjusted net income margin was 1.7%. See Appendices B and C for additional details

● Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) was $53.5 million, compared to $55.1 million in the prior quarter; Adjusted EBITDA margin decreased 110 basis points sequentially to 11.8%. See Appendix C for additional details

**Management Commentary**

"During the first quarter we experienced modest revenue increases despite weather impacts to start the year. Our Technical Services segment revenues increased 7% sequentially. Within Technical Services, Cudd Energy Services' pressure pumping saw the largest percentage increase at 20% followed by Cudd Pressure Control's nitrogen service line which increased 13%. Thru Tubing Solutions' downhole tools increased 11% driven by higher activity supported by new technologies. Our Support Services segment revenues were flat sequentially, as the first quarter typically sees the biggest weather impact," stated Ben M. Palmer, RPC's President and Chief Executive Officer.

"The year started off with winter storms disrupting activity across multiple basins which was followed by significant geopolitical events that meaningfully increased oil prices. We are seeing signs of optimism including increased bidding activity, as well as a number of operators electing to maintain activity, rather than following through with previously announced reduction plans. However, industry concerns about the duration of higher commodity prices and price volatility are currently limiting any significant reevaluation of spending plans. As we look ahead, we will be measured in our approach focusing on returns on capital and strategically investing where prudent."

First Quarter 2026 Earnings Release

**1Q:26 Consolidated Financial Results (sequential comparisons to previous quarter)**

***Revenues*** were $454.8 million, up 7%. Within the Technical Services segment, we saw revenues increase 7% sequentially with pumping, nitrogen, and downhole tools seeing double digit percentage increases. Within the Support Services segment revenues were essentially flat.

***Cost of revenues***, which excludes depreciation and amortization of $37.1 million, was $355.6 million, up from $336.6 million. Cost of revenues was most impacted by costs that typically vary with activity and job mix, specifically materials & supplies and fuel sourced for customers.

***Selling, general and administrative expenses*** were $48.2 million, slightly up from $47.7 million.

***Acquisition related employment costs*** were approximately $7.3 million during 1Q:26 and 4Q:25, and represent non-cash accounting adjustments related to the Pintail acquisition costs that are contingent upon continued employment.

**Depreciation and amortization** was $42.9 million during 1Q:26, and 4Q:25 was $39.1 million. The fourth quarter reflected a $2.8 million reduction in depreciation and amortization due to the change in wireline cable accounting. See Appendix C for additional details.

***Interest income*** totaled $1.8 million, approximating the prior quarter.

***Interest expense*** totaled $830 thousand, approximating the prior quarter.

***Income tax provision*** was $3.5 million, primarily due to the disproportionate impact of permanent non-deductible items, mainly acquisition related employment costs, on a relatively low pretax income.

***Net earnings and Earnings per share*** totaled $0.9 million and $0.00 respectively, versus net loss of $3.1 million and diluted loss per share of $0.02, respectively, in 4Q:25. Net income margin increased 90 basis points sequentially to 0.2%.

***Adjusted net income and Adjusted diluted EPS*** were $7.6 million and $0.03, respectively, versus $9.4 million and $0.04, respectively, in 4Q:25. Adjusted net income margin decreased to 1.7% from 2.2% in 4Q:25.

***Adjusted EBITDA*** was $53.5 million, down from $55.1 million. Adjusted EBITDA margin decreased 110 basis points sequentially to 11.8%. See Appendix C for additional details.

**Balance Sheet, Cash Flow and Capital Allocation**

***Cash and cash equivalents*** decreased slightly to $200.7 million at the end of the first quarter compared to the end of 2025, with no outstanding borrowings under the Company's $100 million revolving credit facility.

***Net cash provided by operating activities and Free cash flow*** were $31.2 million and ($0.9) million, respectively, year-to-date through 1Q:26. Working capital was a significant use of cash during the quarter primarily due to higher accounts receivable resulting from revenue increases.

***Payment of dividends*** totaled $8.9 million year-to-date. As previously announced, the Board of Directors declared a regular quarterly cash dividend of $0.04 per share, payable on June 10, 2026, to common stockholders of record at the close of business on May 11, 2026.

Revenues were $20.5 million, essentially flat

<sup>(1)</sup> Beginning in the fourth quarter of 2025, wireline cables, previously capitalized and depreciated over 18 months, began being expensed due to a change in their estimated useful lives. Wireline cable adjustments in 2025 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 partially 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 2025 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 fourth quarter.

Certain statements and information included in this press release constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include statements that look forward in time or express management's beliefs, expectations or hopes. In particular, such statements include, without limitation: that the Company is seeing signs of optimism, including increased bidding activity, as well as a number of operators electing to maintain activity, rather than previously announced reduction plans; that industry concerns about the duration of higher commodity prices and price volatility are currently limiting any significant reevaluation of spending plans; and the Company's expectation for future periods that it will follow a measured approach focusing on returns on capital and strategically investing in a prudent manner.

**Non-GAAP Measures**

RPC, Inc. has used the non-GAAP financial measures of 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, without regard to acquisition related employment costs and changes in our accounting for purchases of wireline cables, and in the case of Adjusted EBITDA and Adjusted EBITDA margin, without regard to changes in our capital structure. 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.

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 <u>www.rpc.net</u>.

<sup>(1)</sup> Beginning in the fourth quarter of 2025, wireline cables, previously capitalized and depreciated over 18 months, began being expensed due to a change in their estimated useful lives. Wireline cable adjustments in 2025 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 partially 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 2025 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 fourth quarter.
