Selling, general and administrative ("SG&A") expenses increased to $65.1 million for the three months ended June 30, 2018 from $38.5 million for the three months ended March 31, 2018 and $7.7 million for the three months ended June 30, 2017. The increase from the second quarter of 2017 to the second quarter of 2018 is primarily attributable to $28.3 million in bad debt expense and $17.5 million in non-employee non-cash equity compensation expense. The increase from the first quarter of 2018 to the second quarter of 2018 is primarily attributable to $17.5 million in non-employee non-cash equity compensation expense and a $2.7 million increase in bad debt expense.
SG&A expenses, as a percentage of total revenue, were 12% for the three months ended June 30, 2018 compared to 8% for the three months ended March 31, 2018 and 8% for the three months ended June 30, 2017. Excluding bad debt and non-employee non-cash equity compensation expenses, SG&A expenses as a percentage of total revenue were 3.6% for the three months ended June 30 2018, compared to 2.6% for the three months ended March 31, 2018 and 7.8% for the three months ended June 30, 2017.

Acquisitions

During the second quarter of 2018, Mammoth acquired WTL Oil LLC ("WTL"), a company engaged in the hauling of crude oil in Oklahoma. Immediately following the closing of the transaction, WTL embarked on an expansion program to grow its fleet to 49 crude hauling trucks (from 20 at the time of acquisition) and entered the west Texas market.

Additionally, during the second quarter of 2018, Mammoth acquired RTS Energy Services LLC ("RTS"), a company engaged in the cementing and acidizing of oil and gas wells in west Texas. Through the RTS transaction, Mammoth expanded its service offerings into the Permian Basin with top quality operators.

Initiation of Quarterly Cash Dividend

On July 16, 2018, Mammoth announced that its Board of Directors initiated a quarterly dividend policy and declared its first quarterly cash dividend of $0.125 per share of common stock, to be paid on August 14, 2018 to stockholders of record as of the close of business on August 7, 2018.

Strong financial results and a favorable outlook support some balanced return of capital to Mammoth's stockholders. The regular quarterly cash dividend provides benefit to Mammoth’s existing stockholders as well as broadening Mammoth’s exposure to additional income oriented investors.

Liquidity

As of June 30, 2018, Mammoth had cash on hand totaling $10.7 million and no borrowings outstanding under its revolving credit facility. As of June 30, 2018, the Company had approximately $162.7 million of available borrowing capacity under its revolving credit facility, after giving effect to $6.5 million of outstanding letters of credit, resulting in total liquidity of approximately $173.4 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 filed on Form 10-K with the Securities and Exchange Commission ("SEC") on February 28, 2018, 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.

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.

3




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):

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES


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. 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.
