First Quarter net income of $28 million, or $0.63 per diluted share
First Quarter Adjusted EBITDA of $83 million
Trailing twelve months after tax return on invested capital (ROIC) of 29%
Declared $0.125 dividend for the first quarter of 2019

OKLAHOMA CITY, OKLAHOMA, May 1, 2019 - Mammoth Energy Services, Inc. ("Mammoth" or the "Company") (NASDAQ: TUSK) today reported financial and operational results for the quarter ended March 31, 2019.

Financial Highlights for the First Quarter of 2019:

Total revenue was $262.1 million for the three months ended March 31, 2019, down 6% sequentially from $278.2 million for the three months ended December 31, 2018 and down 47% from $494.2 million for the three months ended March 31, 2018.

Net income for the three months ended March 31, 2019 was $28.3 million, or $0.63 per fully diluted share, a 58% decrease from $68.2 million, or $1.51 per fully diluted share, for the three months ended December 31, 2018 and a 49% decrease from $55.5 million, or $1.24 per fully diluted share, for the three months ended March 31, 2018.

Adjusted EBITDA (as defined and reconciled below) was $82.8 million for the three months ended March 31, 2019, a slight decrease from $84.3 million for the three months ended December 31, 2018 and a 37% decline from $130.8 million for the three months ended March 31, 2018.

Arty Straehla, Mammoth's Chief Executive Officer, stated, "The first quarter of 2019 saw improved utilization of our oilfield completions focused businesses as E&P budgets were reset and oil prices experienced a steady increase throughout the quarter. While pressure pumping pricing remains challenged, conversations with customers suggest the possibility for tighter industry conditions for the back half of the year. Demand for Northern White sand is strengthening, with our average pricing up approximately 90% from the lows experienced in fourth quarter of 2018. The movement of our infrastructure equipment from Puerto Rico back to the continental U.S. is progressing and beginning to displace equipment currently being rented, allowing us to deploy additional crews for our Continental U.S. customers."

Infrastructure Services

Mammoth's infrastructure services segment contributed revenues of $108.7 million for the three months ended March 31, 2019, a 32% decrease from $159.6 million for the three months ended December 31, 2018 and a 67% decrease from $325.5 million for the three months ended March 31, 2018. During the first quarter of 2019, our crew staffing levels in Puerto Rico reached a high of approximately 500 in January. As of March 31, 2019, a small contingent of non-billable personnel remained on the island to facilitate the demobilization of our remaining equipment.  

Pressure Pumping Services

Mammoth's pressure pumping division contributed revenues (inclusive of inter-segment revenues) of $92.1 million for the three months ended March 31, 2019, a 27% increase from $72.8 million for the three months ended December 31, 2018 and a 9% decrease from $101.1 million for the three months ended March 31, 2018.





Mammoth's pressure pumping division completed a total of 1,889 stages for the three months ended March 31, 2019, a 62% increase from 1,164 stages for the three months ended December 31, 2018 and a 13% increase from 1,672 stages for the three months ended March 31, 2018. An average of 4.4 of our 6 fleets remained active throughout the first quarter of 2019.
  
Natural Sand Proppant Services

Mammoth's natural sand proppant division contributed revenues (inclusive of inter-segment revenues) of $37.9 million for the three months ended March 31, 2019, a 38% increase from $27.4 million for the three months ended December 31, 2018 and a 26% decrease from $51.0 million for the three months ended March 31, 2018.

The Company sold 665,806 tons of sand during the three months ended March 31, 2019, a 17% increase from the 569,195 tons sold during the three months ended December 31, 2018 and a 9% decrease from the 735,584 tons sold during the three months ended March 31, 2018. The Company's average production costs were approximately $12 per ton during the first quarter of 2019.

The Company’s rental division drove a majority of the increase from the prior periods with the average amount of equipment on rent increasing from 357 for the three months ended March 31, 2018 to 500 for the three months ended December 31, 2018.  An average of 621 pieces of equipment were rented during the three months ended March 31, 2019.

MAMMOTH ENERGY SERVICES, INC.
RECONCILIATION OF NON-GAAP FINANCIAL MEASURES


Adjusted EBITDA

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of the Company's financial statements, such as industry analysts, investors, lenders and rating agencies. Mammoth defines Adjusted EBITDA as net income (loss) before depreciation, depletion, amortization and accretion expense, impairment of long-lived assets, acquisition related costs, public offering costs, stock based compensation, interest expense, net, other (income) expense, net (which is comprised of the (gain) or loss on disposal of long-lived assets) and provision (benefit) for income taxes, further adjusted to add back interest on trade accounts receivable. The Company excludes the items listed above from net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within the energy service industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income (loss) or cash flows from operating activities as determined in accordance with GAAP or as an indicator of Mammoth's operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. Mammoth's computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. The Company believes that Adjusted EBITDA is a widely followed measure of operating performance and may also be used by investors to measure its ability to meet debt service requirements.

The following tables provide a reconciliation of Adjusted EBITDA to the GAAP financial measure of net income (loss) on a consolidated basis and for each of the Company's segments (in thousands):

After Tax Return on Invested Capital

After tax return on invested capital is a supplemental non-GAAP measure that is used by management to evaluate the Company's performance. Mammoth defines after tax return on invested capital as net income divided by total capital employed, which is the average of ending debt and equity for the last two years. Management believes after tax return on invested capital is a useful measure of how effectively the Company uses capital to generate profits and it provides additional insight for analysts and investors in evaluating the Company's financial and operating performance. After tax return on invested capital should not be considered in isolation or as a substitute for financial measures reported in accordance with GAAP. The following table provides the calculation of after tax return on invested capital using the GAAP financial measures of net income, total debt and total equity.
