Exhibit 99

RPC, Inc. Reports Third Quarter 2017 Financial Results

ATLANTA, October 25, 2017 - RPC, Inc. (NYSE: RES) today announced its unaudited results for the third quarter ended September 30, 2017. 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, 2017, revenues increased by 167.8 percent to $471.0 million compared to $175.9 million in the third quarter of last year. Revenues increased compared to the prior year due to higher activity levels and pricing for our services, higher service intensity, and continued activation of previously idled revenue-producing equipment. Operating profit for the quarter was $97.4 million compared to an operating loss of $56.4 million in the prior year. Net income for the quarter was $57.3 million, or $0.26 diluted earnings per share, compared to net loss of $38.9 million or $0.18 loss per share last year. Earnings before interest, taxes, depreciation and amortization (EBITDA) for the quarter was $137.5 million compared to a loss of $4.4 million in the prior year.¹ For the nine months ended September 30, 2017, revenues increased to $1.2 billion compared to $508.0 million last year. Net income for the nine-month period was $104.8 million, or $0.48 diluted earnings per share, compared to net loss of $120.1 million, or $0.56 loss per share last year.

Cost of revenues during the third quarter of 2017 was $294.8 million, or 62.6 percent of revenues, compared to $146.6 million, or 83.4 percent of revenues, during the third quarter of last year.  Cost of revenues increased primarily due to higher activity levels and service intensity. As a percentage of revenues, cost of revenues decreased due to improved pricing for our services as well as leverage of higher revenues over direct employment costs.

Selling, general and administrative expenses were $39.7 million in the third quarter of 2017 compared to $34.9 million in the third quarter of 2016. These expenses increased due to higher compensation costs, primarily incentive compensation, as well as other expenses consistent with higher activity levels. As a percentage of revenues, these costs decreased to 8.4 percent in the third quarter of 2017 compared to 19.8 percent in the third quarter of 2016, due to the leverage of higher revenues over primarily fixed expenses. Depreciation and amortization decreased to $39.6 million compared to $52.0 million in the third quarter of the prior year due to lower capital expenditures over the previous two years.

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.

Discussion of Sequential Quarterly Financial Results

RPC’s revenues for the quarter ended September 30, 2017 increased by $72.2 million, or 18.1 percent, compared to the second quarter of 2017. Revenues increased due to higher activity levels and improved pricing for our services, as well as activation of previously idled revenue-producing equipment. Cost of revenues during the third quarter of 2017 increased by $40.8 million, or 16.1 percent, due to higher materials and supplies expenses and employment costs related to increased headcount. Selling, general and administrative expenses during the third quarter decreased by 1.4 percent.. RPC’s operating profit during the third quarter was $97.4 million, an increase of $30.4 million, or 45.3 percent, compared to the second quarter operating profit of $67.0 million.

Net income increased from $43.8 million, or $0.20 diluted earnings per share in the second quarter of 2017 to $57.3 million, or $0.26 diluted earnings per share in the third quarter. Earnings per share were negatively impacted by approximately $0.02 due to tax provision adjustments recorded in the third quarter.

Management Commentary

“The U.S. domestic rig count increased again during the third quarter of 2017, though at a much lower sequential rate than in the previous four quarters,” stated Richard A. Hubbell, RPC’s President and Chief Executive Officer. “The average U.S. domestic rig count during the third quarter of 2017 was 946, an increase of 95.1 percent compared to the same period in 2016, and an increase of 5.7 percent compared to the second quarter of 2017. The average price of natural gas during the third quarter was $2.95 per Mcf, a 2.4 percent increase compared to the prior year, and a 4.2 percent decrease compared to the second quarter of 2017. The average price of oil during the third quarter was $48.09 per barrel, a 7.0 percent increase compared to the prior year and relatively unchanged compared to the second quarter of 2017. RPC’s revenues increased at a rate greater than the change in these industry metrics because of our customers’ continued high demand for oilfield service providers capable of operating in highly service-intensive environments.

“We are very pleased with the current operating environment and prospects. Although the increase in the drilling rig count has moderated, we have indications of strong customer activities for the remainder of 2017 and into the beginning of 2018. During the third quarter RPC began to experience increased labor cost and raw material inflation, but have managed these cost increases in order to minimize the impact on our profitability. As we discussed during the third quarter, we have ordered additional pressure pumping equipment as well as activated substantially all of our previously idled equipment. We finished the third quarter with $136.9 million in cash with no outstanding debt. Capital expenditures during the quarter were $44.4 million, directed toward both maintenance of our equipment and initial payments on new revenue-producing equipment. In addition, we returned capital to our shareholders by repurchasing 726,889 RPC common shares on the open market during the quarter, bringing the total amount of shares repurchased during the first nine months of 2017 to 1,074,889,” concluded Hubbell.

Third Quarter 2017 Earnings Release

Technical Services revenues increased by 179.0 percent for the quarter compared to the prior year due to improved pricing, higher activity levels and a larger active fleet of revenue-producing equipment as compared to the prior year, particularly within our pressure pumping service line, which is the largest service line within Technical Services. Support Services revenues increased by 21.7 percent during the quarter compared to the prior year due primarily to improved activity levels in the rental tool service line, which is the largest service line within this segment. Technical Services reported an operating profit during the quarter compared to an operating loss in the prior year, while Support Services reported operating losses for the third quarters of 2017 and 2016. RPC’s corporate expenses increased during the third quarter of 2017 as compared to the prior year due to expenses which vary with higher activity levels and profitability, such as incentive compensation.

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.
