OKLAHOMA CITY, OKLAHOMA, March 14, 2019 - Mammoth Energy Services, Inc. ("Mammoth" or the "Company") (NASDAQ: TUSK) today reported financial and operational results for the fourth quarter and full year ended December 31, 2018.

Financial Highlights for the Fourth Quarter and Full Year 2018:

Total revenue was $278.2 million for the three months ended December 31, 2018, down 28% sequentially from $384.0 million for the three months ended September 30, 2018 and down 25% from $369.0 million for the three months ended December 31, 2017. Total revenue was $1.7 billion for the year ended December 31, 2018, a 144% increase from $691.5 million for the year ended December 31, 2017.

Net income for the three months ended December 31, 2018 was $68.2 million, or $1.51 per fully diluted share, a $1.2 million decrease from $69.5 million, or $1.54 per fully diluted share, for the three months ended September 30, 2018 and an increase of $2.3 million from $65.9 million, or $1.48 per fully diluted share, for the three months ended December 31, 2017. Net income was $236.0 million, or $5.24 per fully diluted share, for the year ended December 31, 2018, a 300% increase from $59.0 million, or $1.42 per fully diluted share, for the year ended December 31, 2017.

Adjusted EBITDA (as defined and reconciled below) was $84.3 million for the three months ended December 31, 2018, a $99.3 million decrease from $183.6 million for the three months ended September 30, 2018 and a $26.2 million decline from $110.5 million for the three months ended December 31, 2017. Adjusted EBITDA was $547.3 million for the year ended December 31, 2018, a 231% increase from $165.3 million for the year ended December 31, 2017.

Arty Straehla, Mammoth's Chief Executive Officer, stated, "2018 was another strong year for Mammoth as we posted record levels of total revenue, net income and adjusted EBITDA. In addition, we strategically invested in high margin businesses, returned $11 million to stockholders through dividends and positioned ourselves to take advantage of M&A opportunities. Since going public in late 2016, adjusted EBITDA has grown more than 12 times to $547 million in 2018 from $41 million in 2016. Despite continuing volatility in commodity prices and reductions in capital expenditure budgets at many of our customers, oilfield activity levels have been improving so far in 2019 from the levels experienced in the fourth quarter of 2018. Our six frac fleets have experienced full utilization since late January and demand and pricing for our sand is getting stronger."

On October 19, 2018, Mammoth entered into an amended and restated five-year asset backed revolving credit facility led by PNC Capital Markets with a maximum revolving advance amount at closing of $185 million and the potential to increase the facility by up to an additional $165 million.

As of December 31, 2018, Mammoth had cash on hand totaling $67.6 million and no borrowings outstanding under its revolving credit facility. As of December 31, 2018, the Company had approximately $175.8 of available borrowing capacity under its revolving credit facility, after giving effect to $8.4 million of outstanding letters of credit, resulting in total liquidity of approximately $243.4 million.

Explanatory Note Regarding Financial Information

The financial information contained in this release should be read in conjunction with the financial information contained in Mammoth’s Annual Report to be filed on Form 10-K with the Securities and Exchange Commission ("SEC"), Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings.

The Company's Chief Executive Officer and Chief Financial Officer comprise the Company's Chief Operating Decision Maker function ("CODM"). Segment information is prepared on the same basis that the CODM manages the segments, evaluates the segment financial statements and makes key operating and resource utilization decisions. Segment evaluation is determined on a quantitative basis based on a function of operating income (loss) as well as a qualitative basis, such as nature of the product and service offerings and types of customers.

Based on its assessment of Financial Accounting Standards Board guidance at December 31, 2018, the Company identified three reportable segments: infrastructure services, pressure pumping services and natural sand proppant services. For the year ended December 31, 2017, the Company identified four reportable segments consisting of infrastructure services, pressure pumping services, natural sand proppant services and contract land and directional drilling services. The Company changed its reportable segment presentation in 2018, as it determined based upon both a quantitative and qualitative basis that the contract land and directional drilling services segment, which previously included Bison Drilling and Field Services LLC, Bison Trucking LLC, Panther Drilling Systems LLC, Mako Acquisitions LLC and White Wing Tubular LLC, is not of continuing significance. The Company now includes the results of the entities previously included in the contract land and directional drilling services segment in its reconciling column titled "All Other" in the tables below. The financial results by segment below for the three months ended September 30, 2018 and the three months and year ended December 31, 2017 have been retroactively adjusted to reflect this change in reportable segments.

On June 5, 2017, the Company completed the acquisition of (1) Sturgeon Acquisitions, LLC and its wholly owned subsidiaries Taylor Frac LLC, Taylor RE, LLC and South River, LLC (collectively, "Sturgeon"), (2) Stingray Energy Services and (3) Stingray Cementing (together with Stingray Energy Services, the “Stingray Acquisition”) in exchange for the issuance by Mammoth of an aggregate of 7,000,000 shares of its common stock.

Prior to the acquisition, the Company and Sturgeon were under common control and it is required under accounting principles generally accepted in the Unites States of America ("GAAP") to account for this common control acquisition in a manner similar to the pooling of interest method of accounting. Therefore, the Company's historical financial information has been recast to combine Sturgeon with the Company as if the acquisition had been completed at commencement of Sturgeon's operations on September 13, 2014.

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, equity based compensation, stock based compensation, bargain purchase gain, 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. 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):

Adjusted Net Income and Adjusted Earnings per Share

Adjusted net income and adjusted earnings per share are supplemental non-GAAP financial measures that are used by management to evaluate the Company's operating and financial performance. Management believes these measures provide meaningful information about the Company's performance by excluding certain non-cash charges that may not be indicative of the Company's ongoing operating results, such as equity based compensation, that may not be indicative of the Company's ongoing operating results. Adjusted net income and adjusted earnings per share should not be considered in isolation or as a substitute for net income and earnings per share prepared in accordance with GAAP and may not be comparable to other similarly titled measures of other companies. The following tables provide a reconciliation of adjusted net income and adjusted earnings per share to the GAAP financial measures of net income and earnings per share for the periods specified.

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.
