RPC, Inc. Reports Fourth Quarter 2018 Financial Results

ATLANTA, January 23, 2019 - RPC, Inc. (NYSE: RES) today announced its unaudited results for the fourth quarter ended December 31, 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 December 31, 2018, revenues were $376.8 million, a decrease of 11.8 percent, compared to $427.3 million in the fourth quarter of 2017. Revenues decreased due to lower activity levels and lower pricing, primarily within RPC’s pressure pumping service line. Operating profit for the quarter was $19.7 million, a decrease of 67.4 percent, compared to operating profit of $60.3 million in the same period of the prior year. Net income for the fourth quarter was $13.4 million, or $0.06 diluted earnings per share, compared to net income excluding the impact of Tax Reform of $38.4 million, or $0.18 diluted earnings per share, in the fourth quarter of 2017.^[1] Earnings before interest, taxes, depreciation and amortization (EBITDA) for the quarter were $61.7 million, a decrease of 38.9 percent, compared to $101.1 million in the same period of the prior year.^[2]

For the 12 months ended December 31, 2018, revenues increased to $1.72 billion compared to $1.60 billion last year. Net income for the 12 months ended December 31, 2018 was $175.4 million, or $0.82 diluted earnings per share, compared to net income excluding the impact of Tax Reform of $143.2 million, or $0.66 diluted earnings per share, in the same period last year.

Cost of revenues during the fourth quarter of 2018 was $274.4 million, or 72.8 percent of revenues, compared to $285.7 million, or 66.9 percent of revenues, during the fourth quarter of 2017. Cost of revenues decreased due to lower materials and supplies expenses within RPC’s pressure pumping service line, as well as lower maintenance and repair expenses, consistent with lower activity levels. Cost of revenues as a percentage of revenues increased due to lower activity levels within pressure pumping and labor costs that are relatively fixed in the short term.

Selling, general and administrative expenses decreased from $42.0 million in the fourth quarter of 2017 to $40.0 million in the fourth quarter of 2018 due to lower incentive compensation expense consistent with decreased financial performance. As a percentage of revenues, these expenses increased to 10.6 percent in the fourth quarter of 2018 compared to 9.8 percent of revenues in the fourth quarter of 2017, due to decreases in revenues and the relatively fixed nature of these expenses during the short term. Depreciation and amortization increased to $42.6 million compared with $38.0 million in the fourth quarter of the prior year due to capital expenditures made during the previous four quarters.

RPC’s effective tax rate for the fourth quarter of 2018 was 33 percent and 21 percent for the 12 months ended December 31, 2018. The effective tax rate for the fourth quarter of 2018 was high due to lower pretax income and estimate revisions to permanent tax differences. We estimate RPC’s effective tax rate for 2019 will be approximately 25 percent.

Discussion of Sequential Quarterly Financial Results

RPC’s revenues for the quarter ended December 31, 2018 decreased by $63.2 million, or 14.4 percent, compared with the third quarter of 2018 due to year-end budget depletion among many customers and seasonal declines related to holidays. Cost of revenues during the fourth quarter of 2018 decreased by $26.5 million, or 8.8 percent, due to decreases in variable costs, including materials and supplies, fuel, and maintenance. As a percentage of revenues, cost of revenues increased from 68.4 percent in the third quarter of 2018 to 72.8 percent in the fourth quarter of 2018, due to lower revenues and the relatively fixed nature of employment costs during the short term. RPC’s operating profit for the fourth quarter was $19.7 million, a decrease of $34.9 million, or 64.0 percent, compared with operating profit of $54.6 million in the third quarter of 2018. EBITDA for the fourth quarter of 2018 decreased by $36.1 million, or 36.9 percent, compared to the prior quarter.

Management Commentary

“The average U.S. domestic rig count during the fourth quarter of 2018 was 1,073, a 16.5 percent increase compared to the same period in 2017, and a 2.1 percent increase compared to the third quarter of 2018,” stated Richard A. Hubbell, RPC’s President and Chief Executive Officer. “The average price of natural gas during the fourth quarter was $3.78 per Mcf, a 30.3 percent increase compared to the prior year, and a 29.0 percent increase compared to the third quarter of 2018. The average price of oil during the fourth quarter was $59.36 per barrel, a 7.2 percent increase compared to the prior year, but a 14.9 percent decrease compared to the third quarter of 2018.

“Our activity declined compared with the prior quarter due to seasonal weakness, as many customers severely curtailed operations in December. This was most pronounced in our pressure pumping service line. Weather also slightly impacted our activity levels in several markets. As we begin the first quarter of 2019, the significant and unexpected decline in oil prices during the fourth quarter of 2018 is impacting our customers’ drilling and completion plans. During January, several customers notified us that they are re-evaluating their 2019 budgets and current operations until they have a clearer view of the near-term direction in oil prices. Our customers’ uncertainty and current activity levels cause us to be cautious regarding our 2019 outlook.

“During 2018, we continued our commitment to RPC’s shareholders by repurchasing 2.1 million shares, including approximately 229,000 shares in the fourth quarter. RPC also paid its highest annual per-share dividend since 2012. Including these uses of cash, as well as $242.6 million of capital expenditures during 2018, we finished the year with no outstanding debt and $116.3 million in cash, an increase of $25.2 million compared with the end of 2017,” concluded Hubbell.

Summary of Segment Operating Performance

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

Technical Services includes RPC’s oilfield service lines that utilize people and equipment to perform value-added completion, production and maintenance services directly to a customer’s well. These services are generally directed toward improving the flow of oil and natural gas from producing formations or to address well control issues. The Technical Services segment includes pressure pumping, downhole tools, coiled tubing, hydraulic workover services, nitrogen, surface pressure control equipment, well control and fishing tool operations.

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 13.1 percent for the quarter compared to the same period of the prior year due to lower activity levels in several of the larger service lines within this segment, as well as 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 15.3 percent during the fourth quarter of 2018 compared to the prior quarter due to lower activity levels. Support Services revenues increased by 20.8 percent during the quarter compared to the same period of 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 5.3 percent during the fourth quarter of 2018 compared to the prior quarter due to higher activity levels in most of the service lines within this segment. Technical Services generated a lower operating profit in the fourth quarter of 2018 than in both the prior quarter and the fourth quarter of 2017. Support Services generated an operating profit in the fourth quarter of 2018 and in the prior quarter compared to a loss in the fourth quarter of 2017.

Appendix A

RPC, Inc. has used the non-GAAP financial measures of net income and diluted earnings per share excluding the impact of Tax Reform in today's earnings release, and anticipates using these non-GAAP financial measures in today's earnings conference call. These measures should not be considered in isolation or as a substitute for net income, earnings per share, or other performance measures prepared in accordance with GAAP.

Management believes that presenting the operating results without the impact of Tax Reform enables us to compare our operating performance consistently over various time periods.

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.

Appendix B

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.

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.
