2018 capital expenditures expected to be approximately $125.0 million for expanding infrastructure operations, upgrading and expanding sand facilities, expanding the rental fleet into the mid-continent and adding selective equipment.

Arty Straehla, Mammoth's Chief Executive Officer, stated, "The expansion that Mammoth undertook in 2017 has built a base in three core areas - infrastructure, pressure pumping and sand - that will serve as a platform on which to grow going forward. With the core businesses now in place, we intend to strategically build upon these business segments throughout 2018 and we expect to begin generating significant free cash flows that will be used to bolster our balance sheet, while providing flexibility to expand into the areas where we see the best opportunities."






Pressure Pumping Services

Mammoth's pressure pumping segment contributed revenues (inclusive of intersegment revenues) of $111.9 million on 1,375 stages for the three months ended December 31, 2017, a 46% increase from $76.7 million on 1,617 stages for the three months ended September 30, 2017 and a 247% increase from $32.3 million on 764 stages for the three months ended December 31, 2016. Utilization during the three months ended December 31, 2017 remained strong.

During 2017, the Company expanded its pressure pumping services into the SCOOP/STACK and the Permian Basin with the startup of its fourth, fifth and sixth pressure pumping fleets in June, August and October, respectively.

Infrastructure Services

Mammoth's infrastructure services segment contributed revenues of $209.2 million for the three months ended December 31, 2017, a $195.7 million increase from $13.5 million for the three months ended September 30, 2017.

During 2017, Mammoth broadened its service offerings by expanding into the utility infrastructure business with the formation of Cobra Acquisitions LLC ("Cobra") and the acquisitions of Higher Power Electrical, LLC in April 2017 and 5 Star Electric, LLC in July 2017. Effective October 19, 2017, Cobra entered into an emergency master services agreement with PREPA for repairs to PREPA’s electrical grid as a result of Hurricane Maria. The initial PREPA contract has a one-year term and provided for up to $200.0 million of revenue. The initial PREPA contract was fully applied to services performed by Cobra as of January 3, 2018. On January 28, 2018, Cobra and PREPA amended the initial PREPA contract to increase the total contract amount by an additional $245.4 million of revenue up to a total of $445.4 million in revenue.

Natural Sand Proppant Production

Mammoth's natural sand proppant segment contributed revenues (inclusive of intersegment revenues) of $43.9 million for the three months ended December 31, 2017, a 34% increase from $32.7 million for the three months ended September 30, 2017 and a 285% increase from $11.4 million for the three months ended December 31, 2016. Tons of sand sold for the three months ended December 31, 2017 totaled 600,182 compared to 474,933 for the three months ended September 30, 2017 and 235,860 for the three months ended December 31, 2016.

Mammoth's natural sand proppant segment contributed revenues (inclusive of intersegment revenues) of $117.0 million for the year ended December 31, 2017, up 207% from $38.1 million for the year ended December 31, 2016. Tons of sand sold increased 147% from 683,768 for the year ended December 31, 2016 to 1,690,032 for the year ended December 31, 2017.

The Company completed the acquisitions of Taylor Frac and the Chieftain Sand assets (renamed Piranha Proppant) during the second quarter of 2017 with sand sales from the Piranha Proppant facility commencing in June 2017. The expansion of the Taylor Frac facility is underway with the expectation of increasing capacity to 1.75 Mmtpa (up from 0.7 Mmtpa) by the end of the first quarter of 2018. Once the Taylor Frac expansion is completed, Mammoth's processing capacity will grow to approximately 4 Mmtpa. The Company intends to upgrade certain equipment at its Piranha facility, which is expected to further increase its total sand processing capacity to 4.4 Mmtpa by mid-year 2018.

Contract Land and Directional Drilling Services

Mammoth's contract land and directional drilling segment contributed revenues (inclusive of intersegment revenues) of $13.7 million for the three months ended December 31, 2017 compared to $13.6 million for the three months ended September 30, 2017 and $11.7 million for the three months ended December 31, 2016. Five horizontal rigs on average operated during the three months ended December 31, 2017 and September 30, 2017 compared to four during the three months ended December 31, 2016. The average drilling day rate was $15,964, $14,800 and $13,590, respectively, for the three months ended December 31, 2017, September 30, 2017 and December 31, 2016.

The drilling segment contributed revenues (inclusive of intersegment revenues) of $50.5 million for the year ended December 31, 2017, up 58% from $32.0 million for the year ended December 31, 2016. Five horizontal rigs on average operated during the year ended December 31, 2017, at an average day rate of $14,800 compared to four rigs at an average day

rate of $12,900 during the year ended December 31, 2016. During 2018, Mammoth anticipates five to six rigs will operate on average throughout the year.

Other Services

Mammoth's other services, including coil tubing, pressure control, flowback, cementing, equipment rentals and remote accommodations, contributed revenues (inclusive of intersegment revenues) of $15.2 million for the three months ended December 31, 2017 compared to $17.4 million for the three months ended September 30, 2017 and $10.4 million for the three months ended December 31, 2016.

Revenues for other services (inclusive of intersegment revenues) were $51.7 million and $41.0 million, respectively, for the years ended December 31, 2017 and 2016. The increase is primarily due to revenues derived from Stingray Cementing and Stingray Energy Services, which were acquired in June 2017.

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses increased to $27.4 million for the three months ended December 31, 2017 from $8.0 million for the three months ended September 30, 2017 and $6.0 million for the three months ended December 31, 2016. The sequential increase is primarily attributable to increased bad debt expense and increased compensation and benefits. SG&A expenses, as a percentage of total revenue, were 7% for the three months ended December 31, 2017 compared to 5% for the three months ended September 30, 2017 and 9% for the three months ended December 31, 2016.

SG&A expenses increased to $49.9 million for the year ended December 31, 2017 from $18.0 million for the year ended December 31, 2016. The increase was primarily attributable to increased compensation and benefits, bad debt expense and professional service charges. SG&A expenses, as a percentage of total revenue, were 7% for the year ended December 31, 2017 compared to 8% for the year ended December 31, 2016.

Liquidity

As of December 31, 2017, we had net debt of approximately $94.3 million reflecting $99.9 million in borrowings outstanding under our $170.0 million revolving credit facility and $5.6 million of cash on hand. As of December 31, 2017, we had approximately $62.8 million of available borrowing capacity under our revolving credit facility, after giving effect to $6.5 million of outstanding letters of credit.

Explanatory Note Regarding Financial Information

The historical financial information for periods prior to October 12, 2016, contained in this release relates to Mammoth Energy Partners LP, a Delaware limited partnership (the "Partnership"). On October 12, 2016, the Partnership was converted into a Delaware limited liability company named Mammoth Energy Partners LLC ("Mammoth LLC"), and then each member of Mammoth LLC contributed all of its membership interests in Mammoth LLC to the Company. Prior to the conversion and the contribution, the Company was a wholly-owned subsidiary of the Partnership. Following the conversion and the contribution, Mammoth LLC (as the converted successor to the Partnership) became a wholly-owned subsidiary of the Company.

In October 2016, Mammoth completed its initial public offering (the "IPO") and its common stock began trading on The NASDAQ Global Select Market under the symbol “TUSK.” Unless the context otherwise requires, references in this release to Mammoth or the Company, when used in a historical context for periods prior to October 12, 2016 refer to the Partnership and its subsidiaries. References in this release to Mammoth or the Company, when used for periods beginning on or after October 12, 2016 refer to Mammoth and its subsidiaries.

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 the CODM's assessment, effective December 31, 2017, the Company identified four reportable segments: pressure pumping services; infrastructure services; natural sand proppant services; and contract land and directional drilling services. For the year ended December 31, 2016, the Company identified five reportable segments consisting of pressure pumping services, well services, natural sand proppant services, contract land and directional drilling services and other energy services. The Company changed its reportable segment presentation in 2017, as it no longer considers well services activities, which included Redback Energy Services, Redback Coil Tubing and Mammoth Energy Partners, and its other energy services activities, which included Sand Tiger, to be significant to the understanding of the Company's results. The Company now presents the results of its well service and other energy service activities as "Other." Additionally, during 2017, the Company added a new reportable segment for its infrastructure service activities. The financial results by segment below for the three months ended September 30, 2017 and the three months and years ended December 31, 2017 and 2016 reflect this change in reportable segments.

Prior to 2017, information used by the CODM in measuring segment profits or losses did not include intersegment revenues and costs as they were deemed immaterial for decision-making purposes. In 2017, the Company's CODM changed the way segment profits and losses are measured to include intersegment revenues and expenses. The financial results by segment below for the three months ended September 30, 2017 and the three months and years ended December 31, 2017 and 2016 reflect this change in measurement method.

On June 5, 2017, the Company completed the acquisition of (1) Sturgeon Acquisitions, LLC and its wholly owned subsidiaries Taylor Frac LLC, Taylor Real Estate Investments, LLC and South River Road, LLC (collectively, "Sturgeon"); (2) Stingray Energy Services, LLC and (3) Stingray Cementing, LLC (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 United States of America 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, one-time compensation charges associated with the IPO, equity based compensation, interest expense, bargain purchase gain, 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.
