Exhibit 99

RPC, Inc. Reports Third Quarter 2018 Financial Results

ATLANTA, October 24, 2018 - RPC, Inc. (NYSE: RES) today announced its unaudited results for the third quarter ended September 30, 2018. RPC provides a broad range of specialized oilfield services and equipment primarily to independent and major oilfield companies engaged in the exploration, production and development of oil and gas properties throughout the United States and in selected international markets.

For the quarter ended September 30, 2018, revenues were $440.0 million, a decrease of 6.6 percent, compared to $471.0 million in the third quarter of last year. Revenues decreased compared to the same period of the prior year due to lower activity levels and slightly lower pricing, primarily within RPC’s pressure pumping service line. Operating profit for the quarter was $54.6 million, a decrease of 44.0 percent, compared to operating profit of $97.4 million in the same period of the prior year. Net income for the third quarter was $50.0 million or $0.23 diluted earnings per share, including a $0.04 per share favorable discrete tax adjustment, compared to net income of $57.3 million or $0.26 diluted earnings per share in the third quarter of 2017. Earnings before interest, taxes, depreciation and amortization (EBITDA) for the quarter were $97.8 million, a decrease of 28.9 percent, compared to $137.5 million in the prior year.¹

For the nine months ended September 30, 2018, revenues increased to $1.34 billion compared to $1.17 billion last year. Net income for the nine-month period was $162.0 million, or $0.75 diluted earnings per share, compared to $104.8 million, or $0.48 diluted earnings per share in the same period last year.

Cost of revenues during the third quarter of 2018 was $300.9 million, or 68.4 percent of revenues, compared to $294.8 million, or 62.6 percent of revenues, during the third quarter of last year. Cost of revenues increased primarily due to higher employment costs, partially offset by lower materials and supplies expenses, which declined due to lower activity levels, particularly within our pressure pumping service line. Cost of revenues as a percentage of revenues increased due to inefficiencies caused by inconsistent activity levels and higher employment costs.

Selling, general and administrative expenses were $41.8 million in the third quarter of 2018 compared to $39.7 million in the third quarter of 2017. As a percentage of revenues, these expenses increased to 9.5 percent in the third quarter of 2018 compared to 8.4 percent of revenues in the third quarter of 2017, due to relatively fixed nature of these expenses during the short term. Depreciation and amortization increased to $43.0 million compared to $39.6 million in the third quarter of the prior year due to capital expenditures made during the previous four quarters.

¹ EBITDA is a financial measure which does not conform to generally accepted accounting principles (GAAP). Additional disclosure regarding this non-GAAP financial measure is disclosed in Appendix A to this press release.

Management Commentary

“The average U.S. domestic rig count during the third quarter of 2018 was 1,051, an 11.1 percent increase compared to the same period in 2017, and a 1.2 percent increase compared to the second quarter of 2018,” stated Richard A. Hubbell, RPC’s President and Chief Executive Officer. “The average price of natural gas during the third quarter was $2.93 per Mcf, a 0.7 percent decrease compared to the prior year, and a 2.8 percent increase compared to the second quarter of 2018. The average price of oil during the third quarter was $69.73 per barrel, a 45.0 percent increase compared to the prior year and a 2.5 percent increase compared to the second quarter of 2018.

“Oilfield completion activity increased slightly during the third quarter, as stable oil prices supported our customers’ activities. However, we began to experience weakness in the pricing for our pressure pumping services as additional horsepower continued to enter the market. In addition, pressure pumping fleet efficiencies continued to improve, which has contributed to the overcapacity for this oilfield services market segment. Labor shortages also continue to be a significant issue in our industry. We have not yet experienced any direct impact from Permian Basin takeaway capacity constraints.

“During the third quarter, we continued our commitment to RPC’s shareholders through our dividends. Including this use of cash, as well as $49.9 million of capital expenditures, we finished the third quarter with $128.4 million in cash,” concluded Hubbell.

Summary of Segment Operating Performance

RPC manages two operating segments - Technical Services and Support Services.

Support Services includes RPC’s oilfield service lines that provide equipment for customer use or services to assist customer operations. The equipment and services offered include rental of tubulars and related tools, pipe handling, inspection and storage services, and oilfield training services.

Technical Services revenues decreased by 7.6 percent for the quarter compared to the prior year due to lower activity levels in several of the larger service lines within this segment, as well as slightly lower pricing within our pressure pumping service line, which is the largest service line within Technical Services. On a sequential basis, Technical Services revenues decreased by 6.4 percent during the third quarter of 2018 compared to the prior quarter due to these lower activity levels. Support Services revenues increased by 22.5 percent during the quarter compared to the prior year due primarily to improved activity levels and pricing in the rental tool service line, which is the largest service line within this segment. On a sequential basis, Support Services revenues increased by 3.6 percent during the third quarter of 2018 compared to the prior quarter. Technical Services generated lower operating profit in the third quarter of 2018 than in both the prior quarter and the third quarter of last year. Support Services generated an operating profit in the third quarter of 2018 and in the prior quarter compared to a loss in the third quarter of 2017.

Appendix A

RPC has used the non-GAAP financial measure of earnings before interest, taxes, depreciation and amortization (EBITDA) in today's earnings release, and anticipates using EBITDA in today's earnings conference call. EBITDA should not be considered in isolation or as a substitute for operating income, net income or other performance measures prepared in accordance with U.S. GAAP. RPC uses EBITDA as a measure of operating performance because it allows us to compare performance consistently over various periods without regard to changes in our capital structure. We are also required to use EBITDA to report compliance with financial covenants under our revolving credit facility.

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 below is a reconciliation of EBITDA with Net Income, the most comparable GAAP measure. This reconciliation also appears on RPC's investor website, which can be found on the Internet at www.rpc.net.
