GLOSSARY OF OIL AND NATURAL GAS AND ELECTRICAL INFRASTRUCTURE TERMS
The following is a glossary of certain oil and natural gas industry terms used in this report:
Acidizing
To pump acid into a wellbore to improve a well's productivity or injectivity.
Blowout
An uncontrolled flow of reservoir fluids into the wellbore, and sometimes catastrophically to the surface. A blowout may consist of salt water, oil, natural gas or a mixture of these. Blowouts can occur in all types of exploration and production operations, not just during drilling operations. If reservoir fluids flow into another formation and do not flow to the surface, the result is called an underground blowout. If the well experiencing a blowout has significant open-hole intervals, it is possible that the well will bridge over (or seal itself with rock fragments from collapsing formations) down-hole and intervention efforts will be averted.
Bottomhole assembly
The lower portion of the drillstring, consisting of (from the bottom up in a vertical well) the bit, bit sub, a mud motor (in certain cases), stabilizers, drill collar, heavy-weight drillpipe, jarring devices (“jars”) and crossovers for various threadforms. The bottomhole assembly must provide force for the bit to break the rock (weight on bit), survive a hostile mechanical environment and provide the driller with directional control of the well. Oftentimes the assembly includes a mud motor, directional drilling and measuring equipment, measurements-while-drilling tools, logging-while-drilling tools and other specialized devices.
Cementing
To prepare and pump cement into place in a wellbore.
Coiled tubing
A long, continuous length of pipe wound on a spool. The pipe is straightened prior to pushing into a wellbore and rewound to coil the pipe back onto the transport and storage spool. Depending on the pipe diameter (1 in. to 4 1/2 in.) and the spool size, coiled tubing can range from 2,000 ft. to 23,000 ft. (610 m to 6,096 m) or greater length.
Completion
A generic term used to describe the assembly of down-hole tubulars and equipment required to enable safe and efficient production from an oil or gas well. The point at which the completion process begins may depend on the type and design of the well.
Directional drilling
The intentional deviation of a wellbore from the path it would naturally take. This is accomplished through the use of whipstocks, bottomhole assembly (BHA) configurations, instruments to measure the path of the wellbore in three-dimensional space, data links to communicate measurements taken down-hole to the surface, mud motors and special BHA components and drill bits, including rotary steerable systems, and drill bits. The directional driller also exploits drilling parameters such as weight on bit and rotary speed to deflect the bit away from the axis of the existing wellbore. In some cases, such as drilling steeply dipping formations or unpredictable deviation in conventional drilling operations, directional-drilling techniques may be employed to ensure that the hole is drilled vertically. While many techniques can accomplish this, the general concept is simple: point the bit in the direction that one wants to drill. The most common way is through the use of a bend near the bit in a down-hole steerable mud motor. The bend points the bit in a direction different from the axis of the wellbore when the entire drillstring is not rotating. By pumping mud through the mud motor, the bit turns while the drillstring does not rotate, allowing the bit to drill in the direction it points. When a particular wellbore direction is achieved, that direction may be maintained by rotating the entire drillstring (including the bent section) so that the bit does not drill in a single direction off the wellbore axis, but instead sweeps around and its net direction coincides with the existing wellbore. Rotary steerable tools allow steering while rotating, usually with higher rates of penetration and ultimately smoother boreholes.
Down-hole
Pertaining to or in the wellbore (as opposed to being on the surface).
Down-hole motor
A drilling motor located in the drill string above the drilling bit powered by the flow of drilling mud. Down-hole motors are used to increase the speed and efficiency of the drill bit or can be used to steer the bit in directional drilling operations. Drilling motors have become very popular because of horizontal and directional drilling applications and the day rates for drilling rigs.
Drilling rig
The machine used to drill a wellbore.
Drillpipe or Drill pipe
Tubular steel conduit fitted with special threaded ends called tool joints. The drillpipe connects the rig surface equipment with the bottomhole assembly and the bit, both to pump drilling fluid to the bit and to be able to raise, lower and rotate the bottomhole assembly and bit.
Drillstring or Drill string
The combination of the drillpipe, the bottomhole assembly and any other tools used to make the drill bit turn at the bottom of the wellbore.
Horizontal drilling
A subset of the more general term “directional drilling,” used where the departure of the wellbore from vertical exceeds about 80 degrees. Note that some horizontal wells are designed such that after reaching true 90-degree horizontal, the wellbore may actually start drilling upward. In such cases, the angle past 90 degrees is continued, as in 95 degrees, rather than reporting it as deviation from vertical, which would then be 85 degrees. Because a horizontal well typically penetrates a greater length of the reservoir, it can offer significant production improvement over a vertical well.
Hydraulic fracturing
A stimulation treatment routinely performed on oil and gas wells in low permeability reservoirs. Specially engineered fluids are pumped at high pressure and rate into the reservoir interval to be treated, causing a vertical fracture to open. The wings of the fracture extend away from the wellbore in opposing directions according to the natural stresses within the formation. Proppant, such as grains of sand of a particular size, is mixed with the treatment fluid to keep the fracture open when the treatment is complete. Hydraulic fracturing creates high-conductivity communication with a large area of formation and bypasses any damage that may exist in the near-wellbore area.
Hydrocarbon
A naturally occurring organic compound comprising hydrogen and carbon. Hydrocarbons can be as simple as methane, but many are highly complex molecules, and can occur as gases, liquids or solids. Petroleum is a complex mixture of hydrocarbons. The most common hydrocarbons are natural gas, oil and coal.

i


Mesh size
The size of the proppant that is determined by sieving the proppant through screens with uniform openings corresponding to the desired size of the proppant. Each type of proppant comes in various sizes, categorized as mesh sizes, and the various mesh sizes are used in different applications in the oil and natural gas industry. The mesh number system is a measure of the number of equally sized openings per square inch of screen through which the proppant is sieved.
Mud motors
A positive displacement drilling motor that uses hydraulic horsepower of the drilling fluid to drive the drill bit. Mud motors are used extensively in directional drilling operations.
Natural gas liquids
Components of natural gas that are liquid at surface in field facilities or in gas processing plants. Natural gas liquids can be classified according to their vapor pressures as low (condensate), intermediate (natural gasoline) and high (liquefied petroleum gas) vapor pressure.
Nitrogen pumping unit
A high-pressure pump or compressor unit capable of delivering high-purity nitrogen gas for use in oil or gas wells. Two basic types of units are commonly available: a nitrogen converter unit that pumps liquid nitrogen at high pressure through a heat exchanger or converter to deliver high-pressure gas at ambient temperature, and a nitrogen generator unit that compresses and separates air to provide a supply of high pressure nitrogen gas.
Plugging
The process of permanently closing oil and gas wells no longer capable of producing in economic quantities. Plugging work can be performed with a well servicing rig along with wireline and cementing equipment; however, this service is typically provided by companies that specialize in plugging work.
Plug
A down-hole packer assembly used in a well to seal off or isolate a particular formation for testing, acidizing, cementing, etc.; also a type of plug used to seal off a well temporarily while the wellhead is removed.
Pounds per square inch
A unit of pressure. It is the pressure resulting from a one pound force applied to an area of one square inch.
Pressure pumping
Services that include the pumping of liquids under pressure.
Producing formation
An underground rock formation from which oil, natural gas or water is produced. Any porous rock will contain fluids of some sort, and all rocks at considerable distance below the Earth’s surface will initially be under pressure, often related to the hydrostatic column of ground waters above the reservoir. To produce, rocks must also have permeability, or the capacity to permit fluids to flow through them.
Proppant
Sized particles mixed with fracturing fluid to hold fractures open after a hydraulic fracturing treatment. In addition to naturally occurring sand grains, man-made or specially engineered proppants, such as resin-coated sand or high-strength ceramic materials like sintered bauxite, may also be used. Proppant materials are carefully sorted for size and sphericity to provide an efficient conduit for production of fluid from the reservoir to the wellbore.
Resource play
Accumulation of hydrocarbons known to exist over a large area.
Shale
A fine-grained, fissile, sedimentary rock formed by consolidation of clay- and silt-sized particles into thin, relatively impermeable layers.
Tight oil
Conventional oil that is found within reservoirs with very low permeability. The oil contained within these reservoir rocks typically will not flow to the wellbore at economic rates without assistance from technologically advanced drilling and completion processes. Commonly, horizontal drilling coupled with multistage fracturing is used to access these difficult to produce reservoirs.
Tight sands
A type of unconventional tight reservoir. Tight reservoirs are those which have low permeability, often quantified as less than 0.1 millidarcies.
Tubulars
A generic term pertaining to any type of oilfield pipe, such as drill pipe, drill collars, pup joints, casing, production tubing and pipeline.
Unconventional resource
An umbrella term for oil and natural gas that is produced by means that do not meet the criteria for conventional production. What has qualified as “unconventional” at any particular time is a complex function of resource characteristics, the available exploration and production technologies, the economic environment, and the scale, frequency and duration of production from the resource. Perceptions of these factors inevitably change over time and often differ among users of the term. At present, the term is used in reference to oil and gas resources whose porosity, permeability, fluid trapping mechanism, or other characteristics differ from conventional sandstone and carbonate reservoirs. Coalbed methane, gas hydrates, shale gas, fractured reservoirs and tight gas sands are considered unconventional resources.
Wellbore
The physical conduit from surface into the hydrocarbon reservoir.
Well stimulation
A treatment performed to restore or enhance the productivity of a well. Stimulation treatments fall into two main groups, hydraulic fracturing treatments and matrix treatments. Fracturing treatments are performed above the fracture pressure of the reservoir formation and create a highly conductive flow path between the reservoir and the wellbore. Matrix treatments are performed below the reservoir fracture pressure and generally are designed to restore the natural permeability of the reservoir following damage to the near wellbore area. Stimulation in shale gas reservoirs typically takes the form of hydraulic fracturing treatments.
Wireline
A general term used to describe well-intervention operations conducted using single-strand or multi-strand wire or cable for intervention in oil or gas wells. Although applied inconsistently, the term commonly is used in association with electric logging and cables incorporating electrical conductors.
Workover
The process of performing major maintenance or remedial treatments on an oil or gas well. In many cases, workover implies the removal and replacement of the production tubing string after the well has been killed and a workover rig has been placed on location. Through-tubing workover operations, using coiled tubing, snubbing or slickline equipment, are routinely conducted to complete treatments or well service activities that avoid a full workover where the tubing is removed. This operation saves considerable time and expense.

ii


The following is a glossary of certain electrical infrastructure industry terms used in this report:
Distribution
The distribution of electricity from the transmission system to individual customers.
Substation
A part of an electrical transmission and distribution system that transforms voltage from high to low, or the reverse.
Transmission
The movement of electrical energy from a generating site, such as a power plant, to an electric substation.

Organization and Nature of Business
Mammoth Energy Services, Inc. (the “Company,” “Mammoth Inc.” or “Mammoth”), together with its subsidiaries, is an integrated, growth-oriented company serving both the oil and gas and the electric utility industries in North America and US territories. Mammoth's subsidiaries provide a diversified set of drilling and completion services to the exploration and production industry including pressure pumping, coil tubing, natural sand and proppant services as well as trucking, drilling, cementing, water transfer among others. In addition, its infrastructure division provides transmission, distribution and logistics services to various public and private owned utilities throughout the US and Puerto Rico.

The Company was incorporated in Delaware in June 2016 as a wholly-owned subsidiary of Mammoth Energy Partners LP, a Delaware limited partnership (the “Partnership” or the “Predecessor”). The Partnership was originally formed by Wexford Capital LP (“Wexford”) in February 2014 as a holding company under the name Redback Inc. and was converted to a Delaware limited partnership in August 2014. On November 24, 2014, Mammoth Energy Holdings LLC (“Mammoth Holdings,” an entity controlled by Wexford), Gulfport Energy Corporation (“Gulfport”) and Rhino Resource Partners LP (“Rhino”) contributed their interest in certain of the entities presented below to the Partnership in exchange for 20 million limited partner units. Mammoth Energy Partners GP, LLC (the “General Partner”) held a non-economic general partner interest.

On October 12, 2016, the Partnership was converted into a Delaware limited liability company named Mammoth Energy Partners LLC (“Mammoth LLC”), and then Mammoth Holdings, Gulfport and Rhino, as all the members of Mammoth LLC, contributed their member interests in Mammoth LLC to Mammoth Inc. Prior to the conversion and the contribution, Mammoth Inc. was a wholly-owned subsidiary of the Partnership. Following the conversion and the contribution, Mammoth LLC (as the converted successor to the Partnership) was a wholly-owned subsidiary of Mammoth Inc. Mammoth Inc. did not conduct any material business operations until Mammoth LLC was contributed to it. On October 19, 2016, Mammoth Inc. closed its initial public offering of 7,750,000 shares of common stock (the “IPO”), which included an aggregate of 250,000 shares that were offered by Mammoth Holdings, Gulfport and Rhino, at a price to the public of $15.00 per share.

On June 29, 2018, Gulfport and MEH Sub LLC ("MEH Sub"), an entity controlled by Wexford, (collectively, the "Selling Stockholders") completed an underwritten secondary public offering of 4,000,000 shares of the Company’s common stock at a purchase price to the Selling Stockholders of $38.01 per share. The Selling Stockholders granted the underwriters an option to purchase up to an aggregate of 600,000 additional shares of the Company's common stock at the same purchase price. This option was exercised, in part, and on July 30, 2018, the underwriters purchased an additional 385,000 shares of common stock from the Selling Stockholders at the same price per share. The Selling Stockholders received all proceeds from this offering.

At September 30, 2018 and December 31, 2017, Wexford, Gulfport and Rhino beneficially owned the following shares of outstanding common stock of Mammoth Inc.:

Operations

The Company's infrastructure services include electric utility contracting services focused on the repair, upgrade, maintenance and construction of transmission and distribution networks. The Company’s infrastructure services also provide storm repair and restoration services in response to natural disasters including hurricanes, ice or other storm-related damage. The Company's pressure pumping services include equipment and personnel used in connection with the completion and early production of oil and natural gas wells. The Company's natural sand proppant services include the

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

distribution and production of natural sand proppant that is used primarily for hydraulic fracturing in the oil and gas industry. The Company's contract land and directional drilling services provides drilling rigs and directional tools for both vertical and horizontal drilling of oil and natural gas wells and salt water disposal wells. The Company also provides other services, including coil tubing units used to enhance the flow of oil and natural gas, flowback, cementing, aciziding, equipment rentals, crude oil hauling, water transfer and remote accommodations.

All of the Company’s operations are in North America and in the Caribbean. During the periods presented, the Company has operated its oil and natural gas businesses in the Permian Basin, the Utica Shale, the Eagle Ford Shale, the Marcellus Shale, the Granite Wash, the SCOOP, the STACK, the Cana-Woodford Shale, the Cleveland Sand and the oil sands located in Northern Alberta, Canada. The Company operates its energy infrastructure services primarily in the northeast, southwest and midwest portions of the United States and Puerto Rico. The Company's oil and natural gas business depends in large part on the conditions in the oil and natural gas industry and, specifically, on the amount of capital spending by its customers. Any prolonged increase or decrease in oil and natural gas prices affects the levels of exploration, development and production activity, as well as the entire health of the oil and natural gas industry. Changes in the commodity prices for oil and natural gas could have a material effect on the Company’s results of operations and financial condition. The Company’s business also depends on infrastructure spending on maintenance, upgrade, expansion and repair and restoration. Any prolonged decrease in spending by electric utility companies or delays or reductions in government appropriations could have a material adverse effect on the Company’s results of operations and financial condition.

Basis of Presentation and Significant Accounting Policies

Basis of Presentation
The accompanying unaudited condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries and the variable interest entity ("VIE") for which the Company is the primary beneficiary. All material intercompany accounts and transactions have been eliminated.

This report has been prepared in accordance with the rules and regulations of the Securities and Exchange Commission, and reflects all adjustments, which in the opinion of management are necessary for the fair presentation of the results for the interim periods, on a basis consistent with the annual audited consolidated financial statements. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the summary of significant accounting policies and notes thereto included in the Company’s most recent annual report on Form 10-K.

On June 5, 2017, the Company acquired Sturgeon Acquisitions LLC ("Sturgeon") and Sturgeon's wholly owned subsidiaries Taylor Frac, LLC, Taylor Real Estate Investments, LLC and South River Road, LLC. Prior to its acquisition of Sturgeon, the Company and Sturgeon were under common control and it is required under 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 for all periods included in the accompanying financial statements has been recast to combine Sturgeon with the Company as if the acquisition had been effective since the date Sturgeon commenced operations. Refer to Note 4 - Acquisitions for additional disclosure regarding the acquisition of Sturgeon.
 
Accounts Receivable
Accounts receivable include amounts due from customers for services performed or goods sold. The Company grants credit to customers in the ordinary course of business and generally does not require collateral. Most areas in which the Company operates provide for a mechanic’s lien against the property on which the service is performed if the lien is filed within the statutorily specified time frame. Customer balances are generally considered delinquent if unpaid by the 30th day following the invoice date and credit privileges may be revoked if balances remain unpaid.

The Company regularly reviews receivables and provides for estimated losses through an allowance for doubtful accounts. In evaluating the level of established reserves, the Company makes judgments regarding its customers’ ability to make required payments, economic events and other factors. As the financial condition of customers changes, circumstances develop, or additional information becomes available, adjustments to the allowance for doubtful accounts may be required. In the event the Company was to determine that a customer may not be able to make required payments, the Company would increase the allowance through a charge to income in the period in which that determination is made.

6

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

If it is determined that previously reserved amounts are collectible, the Company would decrease the allowance through a credit to income in the period in which that determination is made. Uncollectible accounts receivable are periodically charged against the allowance for doubtful accounts once a final determination is made regarding their uncollectability.

Following is a roll forward of the allowance for doubtful accounts for the year ended December 31, 2017 and the nine months ended September 30, 2018 (in thousands):

In October 2017, Cobra Acquisitions LLC ("Cobra"), one of the Company's subsidiaries, entered into a contract with the Puerto Rico Electric Power Authority ("PREPA") to perform repairs to PREPA’s electrical grid as a result of Hurricane Maria. At December 31, 2017 and through June 30, 2018, the Company reviewed receivables due from PREPA and made specific reserves consistent with Company policy which resulted in additions to the allowance for doubtful accounts totaling $16.0 million and $53.6 million, respectively, for the year ended December 31, 2017 and six months ended June 30, 2018. During the three months ended September 30, 2018, the Company received payment from PREPA for the amount reserved at December 31, 2017 of $16 million. As a result, the Company reversed the 2017 and 2018 additions to the allowance for doubtful accounts from PREPA. The Company expects to receive payment for the 2018 amounts once the Company files its 2018 Puerto Rico tax return and pays any taxes due as calculated by the return. The Company expects that the Puerto Rico 2018 tax return will be filed in mid-2019 and that the taxes due as a result of the 2018 Puerto Rico tax return will be paid in the first quarter of 2019.

Additionally, the Company has made specific reserves consistent with Company policy which resulted in additions to allowance for doubtful accounts totaling $1.4 million and $0.2 million, respectively, for the nine months ended September 30, 2018 and year ended December 31, 2017. The Company will continue to pursue collection until such time as final determination is made consistent with Company policy.

Concentrations of Credit Risk and Significant Customers
Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents in excess of federally insured limits and trade receivables. Following is a summary of our significant customers based on percentages of total accounts receivable balances at September 30, 2018 and December 31, 2017 and percentages of total revenues derived for the three and nine months ended September 30, 2018 and 2017:

Fair Value of Financial Instruments
The Company's financial instruments consist of cash and cash equivalents, trade receivables, trade payables, amounts receivable or payable to related parties, and long-term debt. The carrying amount of cash and cash equivalents, trade receivables, receivables from related parties and trade payables approximates fair value because of the short-term nature

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

of the instruments. The fair value of long-term debt approximates its carrying value because the cost of borrowing fluctuates based upon market conditions.

New Accounting Pronouncements
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02 “Leases” amending the current accounting for leases. Under the new provisions, all lessees will report a right-of-use asset and a liability for the obligation to make payments for all leases with the exception of those leases with a term of 12 months or less.  All other leases will fall into one of two categories: (i) a financing lease or (ii) an operating lease. Lessor accounting remains substantially unchanged with the exception that no leases entered into after the effective date will be classified as leveraged leases. For sale leaseback transactions, a sale will only be recognized if the criteria in the new revenue recognition standard are met. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within that fiscal year. The Company plans to adopt this ASU effective January 1, 2019 utilizing the modified retrospective method of adoption. This new leasing guidance will impact the Company in situations where it is the lessee, and in certain circumstances it will have a right-of-use asset and lease liability on its consolidated financial statements. The Company is in the process of implementing a new lease accounting system in connection with the adoption of this ASU and are continuing to evaluate the impact this new guidance may have on the Company's consolidated financial statements and results of operations.

In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Accounting,” which simplifies the accounting for share-based payments granted to non-employees by aligning the accounting with requirements for employee share-based compensation. Upon transition, this ASU requires non-employee awards to be measured at fair value as of the adoption date. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within that fiscal year. Early adoption is permitted. Currently, the Company has not elected to early adopt this ASU and is evaluating the impact it will have on the Company's consolidated financial statements.

3.
Revenues

Adoption of ASC 606 "Revenues from Contracts with Customers"
In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance. The new guidance requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services.

On January 1, 2018, the Company adopted ASU 2014-09 and its related amendments (collectively, "ASC 606") using the modified retrospective method applied to contracts which were not completed as of January 1, 2018. Revenues for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts continue to be reported under previous revenue recognition guidance. While ASC 606 requires additional disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, its adoption has not had a material impact on the measurement or recognition of the Company's revenues.

The adoption of ASC 606 represents a change in accounting principle. After evaluation of all contracts not completed as of January 1, 2018, the Company determined the cumulative effect of adopting ASC 606 was immaterial, and as such, has not recorded an adjustment to the opening balance of retained earnings on January 1, 2018.

Revenue Recognition
The Company's primary revenue streams include pressure pumping services, infrastructure services, natural sand proppant services, contract land and directional drilling services and other services, which includes coil tubing, pressure control, flowback, cementing, acidizing, equipment rentals, crude oil hauling, water transfer and remote accommodations services. See Note 19 for the Company's revenue disaggregated by type.

Pressure Pumping Services
Pressure pumping services are typically provided based upon a purchase order, contract or on a spot market basis. Services are provided on a day rate, contracted or hourly basis. Generally, the Company accounts for pressure pumping services as a single performance obligation satisfied over time. In certain circumstances, the Company supplies proppant that is utilized for pressure pumping as part of the agreement with the customer. The Company accounts for these pressure pumping agreements as multiple performance obligations satisfied over time. Jobs for these services are typically short-

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

term in nature and range from a few hours to multiple days. Generally, revenue is recognized over time upon the completion of each segment of work based upon a completed field ticket, which includes the charges for the services performed, mobilization of the equipment to the location and personnel.

Pursuant to a contract with one of its customers, the Company has agreed to provide that customer with use of two pressure pumping fleets for the period covered by the contract. Under this agreement, performance obligations are satisfied as services are rendered based on the passage of time rather than the completion of each segment of work. The Company has the right to receive consideration from this customer even if circumstances prevent us from performing work. All consideration owed to the Company for services performed during the contractual period is fixed and the right to receive it is unconditional.

Additional revenue is generated through labor charges and the sale of consumable supplies that are incidental to the service being performed. Such amounts are recognized ratably over the period during which the corresponding goods and services are consumed.

Infrastructure Services
Infrastructure services are typically provided pursuant to master service agreements, repair and maintenance contracts or fixed price and non-fixed price installation contracts. Pricing under these contracts may be unit priced, cost-plus/hourly (or time and materials basis) or fixed price (or lump sum basis). The Company accounts for infrastructure services as a single performance obligation satisfied over time. Revenue is recognized over time as work progresses based on the days completed or as the contract is completed. Under certain customer contracts in our infrastructure services segment, the Company warranties equipment and labor performed for a specified period following substantial completion of the work. 

Natural Sand Proppant Services
The Company sells natural sand proppant through sand supply agreements with its customers. Under these agreements, sand is typically sold at a flat rate per ton or a flat rate per ton with an index-based adjustment. The Company recognizes revenue at the point in time when the customer obtains legal title to the product, which may occur at the production facility, rail origin or at the destination terminal.

Certain of the Company's sand supply agreements contain a minimum volume commitment related to sand purchases whereby the Company charges a shortfall payment if the customer fails to meet the required minimum volume commitment. These agreements may also contain make-up provisions whereby shortfall payments can be applied in future periods against purchased volumes exceeding the minimum volume commitment. If a make-up right exists, the Company has future performance obligations to deliver excess volumes of product in subsequent months. In accordance with ASC 606, if the customer fails to meet the minimum volume commitment, the Company will assess whether it expects the customer to fulfill its unmet commitment during the contractually specified make-up period based on discussions with the customer and management's knowledge of the business. If the Company expects the customer will make-up deficient volumes in future periods, revenue related to shortfall payments will be deferred and recognized on the earlier of the date on which the customer utilizes make-up volumes or the likelihood that the customer will exercise its right to make-up deficient volumes becomes remote. As of September 30, 2018, the Company deferred revenue totaling $0.4 million related to shortfall payments. This amount is included in accrued expenses and other current liabilities on the unaudited condensed consolidated balance sheet. If the Company does not expect the customer will make-up deficient volumes in future periods, the breakage model will be applied and revenue related to shortfall payments will be recognized when the model indicates the customer's inability to take delivery of excess volumes. During the three and nine months ended September 30, 2018, the Company recognized revenue totaling $1.2 million and $1.5 million, respectively, related to shortfall payments.

In certain of the Company's sand supply agreements, the customer obtains control of the product when it is loaded into rail cars and the customer reimburses the Company for all freight charges incurred. The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the sand. If revenue is recognized for the related product before the shipping and handling activities occur, the Company accrues the related costs of those shipping and handling activities.

Contract Land and Directional Drilling Services
Contract drilling services are provided under daywork contracts. Directional drilling services, including motor rentals, are provided on a day rate or hourly basis, and revenue is recognized as work progresses. Performance obligations are satisfied over time as the work progresses based on the measure of output. Mobilization revenue and costs are recognized over the days of actual drilling.

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Other Services
The Company also provides coil tubing, pressure control, flowback, cementing, acidizing, equipment rentals, crude oil hauling, water transfer and remote accommodations services, which are reported under other services. These services are typically provided based upon a purchase order, contract or on a spot market basis. Services are provided on a day rate, contracted or hourly basis. Performance obligations for these services are satisfied over time and revenue is recognized as the work progresses based on the measure of output. Jobs for these services are typically short-term in nature and range from a few hours to multiple days.

Practical Expedients
The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts in which variable consideration is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied distinct good or service that forms part of a single performance obligation.

Acquisitions

(a) Acquisition of WTL Oil

On May 31, 2018, the Company completed its acquisition of WTL Oil LLC ("WTL") for total consideration of $5.5 million in cash to the sellers plus $0.6 million in consideration to be paid upon completion of certain contractual obligations. The seller completed these obligations and the Company paid the additional $0.6 million to the seller during the three months ended September 30, 2018.

The Company used cash on hand and borrowings under its credit facility to fund the acquisition. The acquisition of WTL expanded the Company's service offerings into the crude oil hauling business.

(e) Acquisition of Sturgeon

On March 20, 2017, and as amended on May 12, 2017, the Company entered into a definitive contribution agreement with MEH Sub, Wexford Offshore Sturgeon Corp., Gulfport, Rhino and Mammoth Energy Partners LLC (the “Sturgeon Contribution Agreement”). Under the Sturgeon Contribution Agreement, the Company agreed to acquire, through its wholly-owned subsidiary Mammoth LLC, all outstanding membership interests in Sturgeon, which owns all of the membership interests in Taylor Frac, Taylor RE and South River (collectively, the "Sturgeon subsidiaries"). The acquisition added sand reserves, increased our production capacity and provided access to the Canadian National Railway, which affords access to the Appalachian basin in support of the Company’s pressure pumping services as well as to western Canada.

The acquisition of Sturgeon closed on June 5, 2017. Pursuant to the Sturgeon Contribution Agreement, Mammoth issued 5,607,452 shares of its common stock for all outstanding equity interests in Sturgeon. Based upon a closing price of Mammoth's common stock of $18.50 per share on June 5, 2017, the total purchase price was $103.7 million.

As a result of this transaction, the Company's historical financial information was recast to combine the unaudited condensed consolidated statements of operations and the unaudited condensed consolidated balance sheets of the Company for all periods prior to the closing of this acquisition included in the accompanying financial statements with those of Sturgeon as if the combination had been in effect since Sturgeon commenced operations on September 13, 2014. Any material transactions between the Company and Sturgeon were eliminated. Sturgeon's financial results were incorporated into the Company's natural sand proppant services division.

For the year ended December 31, 2017, $1.3 million of transaction related costs were expensed.

Debt
Mammoth Credit Facility

On November 25, 2014, Mammoth entered into a revolving credit and security agreement with a syndicate of banks that provides for maximum borrowings of $170 million. The facility, as amended, matures on November 25, 2019. Borrowings under this facility are secured by the assets of Mammoth, inclusive of the subsidiary companies. The maximum availability of the facility is subject to a borrowing base calculation prepared monthly. Concurrent with the execution of the facility, the initial advance was used to repay all the debt of the Company then outstanding. Interest is payable monthly at a base rate set by the lead institution’s commercial lending group plus an applicable margin. Additionally, at the Company's request, outstanding balances are permitted to be converted to LIBOR rate plus applicable margin tranches at set increments of $0.5 million. The LIBOR rate option allows the Company to select interest periods from one, two, three or six months. The applicable margin for either the base rate or the LIBOR rate option can vary from 1.5% to 3.0%, based upon a calculation of the excess availability of the line as a percentage of the maximum credit limit. The deferred loan costs associated with this facility are classified in other non-current assets.

At September 30, 2018, there were no outstanding borrowings under the credit facility and $162.5 million of available borrowing capacity, after giving effect to $6.7 million of outstanding letters of credit. At December 31, 2017, there were outstanding borrowings under the credit facility of $99.9 million, leaving an aggregate of $62.8 million of borrowing capacity under the facility, after giving effect to $6.5 million of outstanding letters of credit.

The Mammoth facility also contains various customary affirmative and restrictive covenants. Among the various covenants are specifically identified financial covenants placing requirements of a minimum interest coverage ratio (3.0 to 1.0), maximum leverage ratio (4.0 to 1.0), and minimum availability ($10 million). As of September 30, 2018 and December 31, 2017, the Company was in compliance with the financial covenants under the facility.

On October 19, 2018, the Company and certain of its direct and indirect subsidiaries, as borrowers, entered into an amended and restated revolving credit and security agreement with the lenders party thereto and PNC Bank, National Association, as a lender and as administrative agent for the lenders (the “A&R Credit Agreement”), which amends and restates the revolving credit and security agreement dated as of July 9, 2018, as amended prior to the A&R Credit Agreement, to, among other things, (i) extend the maturity date to October 19, 2023, (ii) increase the maximum revolving advance amount to $185 million, with the ability to further increase the maximum revolving advance amount to $350 million under certain circumstances, (iii) increase the letter of credit sublimit to 20% of the maximum revolving advance amount and (iv) decrease the interest rates applicable to loans.

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Outstanding borrowings under the A&R Credit Agreement bear interest at a per annum rate elected by the Company that is equal to an alternate base rate or LIBOR, in each case plus the applicable margin. The applicable margin ranges from 1.0% to 1.5% per annum in the case of the alternate base rate, and from 2.0% to 2.5% per annum in the case of LIBOR. The applicable margin depends on the amount of excess availability under the A&R Credit Agreement. The A&R Credit Agreement contains various customary affirmative and restrictive covenants including a minimum interest coverage ratio (3.0 to 1.0) and a maximum leverage ratio (4.0 to 1.0). As of October 30, 2018, the credit facility was undrawn.

Sturgeon Credit Facility

On June 30, 2015, Sturgeon entered in to a three-year $25.0 million revolving line of credit secured by substantially all of the assets of Sturgeon (“the Sturgeon revolver”). Advances under the Sturgeon revolver bore interest at 2% plus the greater of (a) the Base Rate as set by the lender's commercial lending group, (b) the sum of the Federal Funds Open Rate plus one half of one percent and (c) the sum of the Daily LIBOR rate. Additionally, at Sturgeon’s request, advances could be obtained at LIBOR plus 3%. The LIBOR rate option allowed Sturgeon to select interest periods from one, two, three or six month LIBOR futures spot rates. The Sturgeon revolver was terminated on June 6, 2017.

Variable Interest Entity

On April 6, 2018, Dire Wolf Energy Services LLC ("Dire Wolf"), a wholly owned subsidiary of the Company, entered into a Voting Trust Agreement with TVPX Aircraft Solutions Inc. (the "Voting Trustee"). Under the Voting Trust Agreement, Dire Wolf transferred 100% of its membership interest in Cobra Aviation Services LLC ("Cobra Aviation") to the Voting Trustee in exchange for Voting Trust Certificates. Dire Wolf retained the obligation to absorb all expected returns or losses of Cobra Aviation. Prior to the transfer of membership interest to the Voting Trustee, Cobra Aviation was a wholly owned subsidiary of Dire Wolf. Cobra Aviation owns and operates a helicopter primarily for services provided to Cobra Acquisitions, a wholly owned subsidiary of the Company. Dire Wolf entered into the Voting Trust Agreement in order to meet certain registration requirements.

Dire Wolf's voting rights are not proportional to its obligation to absorb expected returns or losses of Cobra Aviation and all of Cobra Aviation's activities are conducted on behalf of Dire Wolf, which has disproportionately fewer voting rights; therefore, Cobra Aviation meets the criteria of a VIE. Cobra Aviation's operational activities are directed by Dire Wolf's officers and Dire Wolf has the option to terminate the Voting Trust Agreement at any time. Therefore, the Company, through Dire Wolf, is considered the primary beneficiary of the VIE and consolidates Cobra Aviation at September 30, 2018.

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


The Company's effective tax rate was 51% and 37%, respectively, for the nine months ended September 30, 2018 and 2017. The increase in the effective tax rate is primarily due to the equity based compensation expense recognized during the nine months ended September 30, 2018 as well as a higher tax rate in Puerto Rico, where most of our income was generated during the nine months ended September 30, 2018, compared to the United States tax rate. No income was generated in Puerto Rico during the nine months ended September 30, 2017. Additionally, the Company's effective tax rate can fluctuate as a result of, among other things, discrete items, state income taxes, permanent differences and changes in pre-tax income.

A valuation allowance for deferred tax assets is recognized when it is more likely than not that the benefit of deferred tax assets will not be realized. To assess that likelihood, the Company uses estimates and judgments regarding future taxable income, as well as the jurisdiction in which such taxable income is generated, to determine whether a valuation allowance is required. During the nine months ended September 30, 2018, the Company recorded a change in valuation allowance of $29.7 million related to foreign tax credits that are not expected to be utilized.

The Company evaluates tax positions taken or expected to be taken in preparation of its tax returns and disallows the recognition of tax positions that do not meet a “more likely than not” threshold of being sustained upon examination by the taxing authorities. During the three months ended September 30, 2018, the Company established a reserve for uncertain tax positions totaling $0.4 million related to the filing of certain state income tax returns on a non-unitary basis.

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the “Tax Act”). As a result, the Company recorded a provisional amount for effects of the Tax Act totaling $31.0 million during the fourth quarter of 2017. The Company continues to evaluate the impact of the Tax Act and no revisions were recorded to the provisional amount during the nine months ended September 30, 2018. The Company expects to complete its detailed analysis of the effects of the Tax Act no later than the fourth quarter of 2018.

Equity Based Compensation
Upon formation of certain operating entities by Wexford, Gulfport and Rhino, specified members of management (the “Specified Members”) and certain non-employee members (the “Non-Employee Members”) were granted the right to receive distributions from the operating entities after the contribution member’s unreturned capital balance was recovered (referred to as “Payout” provision).


22

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On November 24, 2014, the awards were modified in conjunction with the contribution of the operating entities to Mammoth. These awards were not granted in limited or general partner units. The awards are for interests in the distributable earnings of the members of MEH Sub, Mammoth’s majority equity holder.

On the IPO closing date, the unreturned capital balance of Mammoth's majority equity holder was not fully recovered from its sale of common stock in the IPO. As a result, Payout did not occur and no compensation cost was recorded.

On June 29, 2018, as part of an underwritten secondary public offering, MEH Sub sold 2,764,400 shares of the Company’s common stock at a purchase price to MEH Sub of $38.01 per share. Additionally, the selling stockholders granted the underwriters an option to purchase additional shares of the Company's common stock at the same purchase price. On July 30, 2018, in connection with the partial exercise of this option, MEH Sub sold an additional 266,026 shares of common stock to the underwriters. MEH Sub received the proceeds from this offering. As a result of the June 29, 2018 offering, a portion of the Non-Employee Member awards reached Payout. During the nine months ended September 30, 2018, the Company recognized equity compensation expense totaling $17.5 million related to these non-employee awards. These awards are at the sponsor level and this transaction had no dilutive impact or cash impact to the Company.

Payout for the remaining awards is expected to occur as the contribution member's unreturned capital balance is recovered from additional sales by MEH Sub of its shares of the Company's common stock or from dividend distributions, which is not considered probable until the event occurs. For the Specified Member awards, the unrecognized amount, which represents the fair value of the award as of the modification dates or grant date, was $5.6 million. For the Non-Employee Member awards, the unrecognized amount, which represents the fair value of the awards as of September 30, 2018 was $36.0 million.

16.
Stock Based Compensation

The 2016 Plan authorizes the Company's Board of Directors or the compensation committee of the Company's Board of Directors to grant restricted stock, restricted stock units, stock appreciation rights, stock options and performance awards. There are 4.5 million shares of common stock reserved for issuance under the 2016 Plan.

Restricted Stock Units

The fair value of restricted stock unit awards was determined based on the fair market value of the Company's common stock on the date of the grant. This value is amortized over the vesting period.

A summary of the status and changes of the unvested shares of restricted stock under the 2016 Plan is presented below.

Included in cost of revenue and selling, general and administrative expenses is stock based compensation expense of $1.4 million and $1.0 million, respectively, for the three months ended September 30, 2018 and 2017 and $4.3 million and $2.6 million, respectively, for the nine months ended September 30, 2018 and 2017.

The Company has insurance coverage for physical partial loss to its assets, employer’s liability, automobile liability, commercial general liability, workers’ compensation and insurance for other specific risks. The Company has also elected in some cases to accept a greater amount of risk through increased deductibles on certain insurance policies. As of September 30, 2018 and December 31, 2017, the policies require a deductible per occurrence of up to $0.3 million. The Company establishes liabilities for the unpaid deductible portion of claims incurred relating to physical loss to its assets, employer's liability, automobile liability, commercial general liability and workers’ compensation based on estimates. As of September 30, 2018 and December 31, 2017, the policies contained an aggregate stop loss of $2.0 million. As of September 30, 2018 and December 31, 2017, accrued claims were $4.3 million and $2.9 million, respectively.

The Company also self-insures its employee health insurance. The Company has coverage on its self-insurance program in the form of a stop loss of $0.2 million per participant and an aggregate stop-loss of $5.8 million for the calendar year ending December 31, 2018. These estimates may change in the near term as actual claims continue to develop. As of September 30, 2018 and December 31, 2017, accrued claims were $3.1 million and $2.1 million, respectively.

Pursuant to certain customer contracts in our infrastructure services segment, the Company warrants equipment and labor performed under the contracts for a specified period following substantial completion of the work. Generally, the warranty is for one year or less. No liabilities were accrued as of September 30, 2018 and December 31, 2017 and no expense was recognized during the nine months ended September 30, 2018 or 2017 related to warranty claims. However, if warranty claims occur, the Company could be required to repair or replace warrantied items, which in most cases are covered by warranties extended from the manufacturer of the equipment. In the event the manufacturer of equipment failed to perform on a warranty obligation or denied a warranty claim made by the Company, the Company could be required to pay for the cost of the repair or replacement.

In the ordinary course of business, the Company is required to provide bid bonds to certain customers in the infrastructure services segment as part of the bidding process. These bonds provide a guarantee to the customer that the Company, if awarded the project, will perform under the terms of the contract. Bid bonds are typically provided for a percentage of the total contract value. Additionally, the Company may be required to provide performance and payment bonds for contractual commitments related to projects in process. These bonds provide a guarantee to the customer that the Company will perform under the terms of a contract and that the Company will pay subcontractors and vendors. If the Company fails to perform under a contract or to pay subcontractors and vendors, the customer may demand that the surety make payments or provide services under the bond. The Company must reimburse the surety for expenses or outlays it incurs. As of September 30, 2018, outstanding bid bonds and performance and payment bonds totaled $20.0 million and $7.1 million, respectively. The estimated the cost to complete projects secured by the performance and payment bonds totaled $3.6 million as of September 30, 2018. As of December 31, 2017, the Company did not have any outstanding bid bonds or performance and payment bonds.

The Company is routinely involved in state and local tax audits. During 2015, the State of Ohio assessed taxes on the purchase of equipment the Company believes is exempt under state law. The Company appealed the assessment and a hearing was held in 2017. As a result of the hearing, the Company received a decision from the State of Ohio. The Company is appealing the decision and while it is not able to predict the outcome of the appeal, this matter is not expected to have a material adverse effect on the Company's financial position, results of operations or cash flows.

On January 26, 2017, a collective action lawsuit alleging that Stingray Pressure Pumping LLC ("Pressure Pumping") failed to pay a class of workers in compliance with the Fair Labor Standards Act was filed titled Ryan Crosby vs. Stingray Pressure Pumping LLC, in the United Stated District Court for the Southern District of Ohio Eastern Division. The parties

reached a settlement of this matter in August 2018. The settlement was paid and did not have a material impact on the Company's financial position, results of operations or cash flows.

On June 27, 2017, a complaint alleging negligence, as a result of a motor vehicle accident, was filed titled Donnelle Banks, individually and as parent and next Friend for Leila Ann Hollis, a minor, vs. Redback Coil Tubing LLC and Mammoth Energy Services, Inc. in the District Court of Gregg County, Texas. The parties reached a settlement of this matter in September 2018. This matter was covered by insurance and did not have a material impact on the Company’s financial position, results of operations or cash flows.

On June 27, 2018, the Company's registered agent notified the Company that it had been served with a putative class action lawsuit titled Wendco of Puerto Rico Inc.; Multisystem Restaurant Inc.; Restaurant Operators Inc.; Apple Caribe, Inc.; on their own behalf and in representation of all businesses that conduct business in the Commonwealth of Puerto Rico vs. Mammoth Energy Services Inc.; Cobra Acquisitions, LLC; D. Grimm Puerto Rico, LLC; Aseguradoras A, B & C; John Doe; Richard Doe, in the Commonwealth of Puerto Rico Superior Court of San Juan. The plaintiffs allege negligent acts by the defendants caused an electrical failure in Puerto Rico resulting in damages of at least $300 million. The Company believes this claim is without merit and will vigorously defend the action. However, the Company continues to evaluate the background facts and at this time is not able to predict the outcome of this lawsuit or whether it will have a material impact on the Company's financial position, results of operations or cash flows.

The Company is involved in various other legal proceedings in the ordinary course of business. Although the Company cannot predict the outcome of these proceedings, legal matters are subject to inherent uncertainties and there exists the possibility that the ultimate resolution of these matters could have a material adverse effect on the Company's business, financial condition, results of operations or cash flows.

Defined contribution plan

The Company sponsors a 401(k) defined contribution plan for the benefit of substantially all employees at their date of hire. The plan allows eligible employees to contribute up to 92% of their annual compensation, not to exceed annual limits established by the federal government. The Company makes discretionary matching contributions of up to 3% of an employee’s compensation and may make additional discretionary contributions for eligible employees. For the three and nine months ended September 30, 2018, the Company paid $1.1 million and $4.5 million, respectively, in contributions to the plan. The Company did not make contributions to the plan during the three and nine months ended September 30, 2017.

Reporting Segments
As of September 30, 2018, our revenues, income before income taxes and identifiable assets are primarily attributable to four reportable segments. The Company principally provides energy services in connection with on-shore drilling of oil and natural gas wells for small to large domestic independent oil and natural gas producers and electric infrastructure services to government-funded utilities, private utilities, public investor-owned utilities and co-operative utilities.

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.

As of September 30, 2018, the Company’s four reportable segments include pressure pumping services ("Pressure Pumping"), infrastructure services ("Infrastructure"), natural sand proppant services ("Sand") and contract land and directional drilling services ("Drilling").

The pressure pumping services segment provides hydraulic fracturing services primarily in the Utica Shale of Eastern Ohio, Marcellus Shale in Pennsylvania, Permian Basin in Texas and the mid-continent region in Oklahoma. The infrastructure services segment provides electric utility infrastructure services to government-funded utilities, private utilities, public investor-owned utilities and co-operative utilities in Puerto Rico and the northeast, southwest and midwest portions of the United States. The sand segment mines, processes and sells sand for use in hydraulic fracturing. The sand segment primarily services the Utica Shale, Permian Basin, SCOOP, STACK and Montney Shale in British Columbia and Alberta, Canada. The contract land and directional drilling services segment provides vertical, horizontal and directional drilling services primarily in the Permian Basin in West Texas.

MAMMOTH ENERGY SERVICES, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Company also provides coil tubing services, pressure control services, flowback services, cementing services, equipment rental services, crude oil hauling services, water transfer services and remote accommodation services. The businesses that provide these services are distinct operating segments, which the CODM reviews independently when making key operating and resource utilization decisions. None of these operating segments meet the quantitative thresholds of a reporting segment and do not meet the aggregation criteria set forth in ASC 280 Segment Reporting. Therefore, results for these operating segments are included in the column labeled "All Other" in the tables below. Additionally, assets for corporate activities, which primarily include cash and cash equivalents, inter-segment accounts receivable, prepaid insurance and certain property and equipment, are included in the All Other column. Although Mammoth LLC, which holds these corporate assets, meets one of the quantitative thresholds of a reporting segment, it does not engage in business activities from which it may earn revenues and its results are not regularly reviewed by the Company's CODM when making key operating and resource utilization decisions. Therefore, the Company does not include it as a reportable segment.

Sales from one segment to another are generally priced at estimated equivalent commercial selling prices. Total revenue and Total cost of revenue amounts included in the Eliminations column in the following tables include inter-segment transactions conducted between segments. Receivables due for sales from one segment to another and for corporate allocations to each segment are included in the Eliminations column for Total assets in the following tables. All transactions conducted between segments are eliminated in consolidation. Transactions conducted by companies within the same reporting segment are eliminated within each reporting segment. The following tables set forth certain financial information with respect to the Company’s reportable segments (in thousands):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and related notes thereto presented in this Quarterly Report and the consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K. This discussion contains forward-looking statements reflecting our current expectations, estimates and assumptions concerning events and financial trends that may affect our future operating results or financial position. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed in Item 1A. "Risk Factors” in this Quarterly Report and in our Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission, or the SEC, on February 28, 2018 and the section entitled “Forward-Looking Statements” appearing elsewhere in this Quarterly Report.

Overview

We are an integrated, growth-oriented company serving both the oil and gas and the electric utility industries in North America and US territories. Our primary business objective is to grow our operations and create value for stockholders through organic opportunities and accretive acquisitions. Our suite of services includes pressure pumping services, infrastructure services, natural sand proppant services, contract land and directional drilling services and other energy services, including coil tubing, flowback, cementing, acidizing, equipment rental, crude oil hauling, water transfer and remote accommodations. Our pressure pumping services division provides hydraulic fracturing services. Our infrastructure services division provides construction, upgrade, maintenance and repair services to the electrical infrastructure industry. Our natural sand proppant services division mines, processes and sells proppant used for hydraulic fracturing. Our contract land and directional drilling services division provides drilling rigs and crews for operators as well as rental equipment, such as mud motors and operational tools, for both vertical and horizontal drilling. In addition to these service divisions, we also provide coil tubing services, pressure control services, flowback services, cementing services, acidizing services, equipment rentals, crude oil hauling services, water transfer and remote accommodations. We believe that the services we offer play a critical role in increasing the ultimate recovery and present value of production streams from unconventional resources as well as maintaining and improving electrical infrastructure. Our complementary suite of services provides us with the opportunity to cross-sell our services and expand our customer base and geographic positioning. We are exploring several opportunities to expand our business lines including, but not limited to, full service transportation, telecommunications, impacts due to the pending rule changes implemented by the international maritime organization, or IMO, in 2020 and general industrial manufacturing as we shift to a broader industrial focus.

On June 5, 2017, we acquired Sturgeon Acquisitions LLC, or Sturgeon, and Sturgeon's wholly owned subsidiaries Taylor Frac, LLC, Taylor Real Estate Investments, LLC and South River Road, LLC. Prior to the acquisition, we and Sturgeon were under common control and, in accordance with generally accepted accounting principles in the United States, or GAAP, we have accounted for this acquisition in a manner similar to the pooling of interest method of accounting. Therefore, our historical financial information for all periods prior to and including the date of this acquisition included in this Quarterly Report on Form 10-Q has been recast to combine Sturgeon's financial results with our financial results as if the acquisition had been effective since Sturgeon commenced operations.

Third Quarter 2018 Highlights and Recent Developments
Extended Pressure Pumping Services and Sand Supply Agreements with Gulfport
On July 10, 2018, we amended our existing agreement with Gulfport pursuant to which we, through our subsidiary Pressure Pumping, provide hydraulic fracturing, stimulation and related completion and rework services to Gulfport with two dedicated frac spreads and related equipment. The amendment extended the term of the existing pressure pumping agreement until December 31, 2021, unless it is terminated earlier in accordance with its terms, and expanded the service area to include both Ohio and Oklahoma. The pressure pumping amendment also provides that Gulfport has the right to suspend pressure pumping services for up to one crew upon a minimum of 90 days prior written notice to Pressure Pumping, with no further payment or other obligation to Pressure Pumping for such suspended crew. Pressure Pumping will be obligated to resume any such suspended pressure pumping services upon 90 days prior written notice by Gulfport, unless such notice is waived by Pressure Pumping.

The pressure pumping amendment also provided for the initial suspension of pressure pumping services to Gulfport for a period July 1, 2018 through September 30, 2018, during which period Pressure Pumping could use the dedicated frac spreads for other customers. If during the initial suspension period Pressure Pumping’s use of the dedicated frac spreads for other customers does not reach a certain level, then Gulfport agreed to pay costs to Pressure Pumping and Pressure Pumping

31


agreed to perform services for Gulfport with respect to such amounts. In addition, if during such initial suspension period Pressure Pumping was unable to utilize the dedicated frac spreads for other customers, Gulfport agreed to pay recoupment costs to Pressure Pumping during the period of October 1, 2018 to December 31, 2018. No amounts were deferred to the period between October 1, 2018 and December 31, 2018.

On August 6, 2018, we amended our existing agreement with Gulfport pursuant to which we, through our subsidiary Muskie Proppant, sell and deliver specified amounts of sand to Gulfport. The amendment extends the term of the existing sand supply agreement until December 31, 2021.

Amended and Restated Credit Facility

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. For additional information related to this amended and restated agreement, see "—Liquidity and Capital Resources—Our Revolving Credit Facility" below.

Industry Overview

Oil and Natural Gas Industry  
  
The oil and natural gas industry has traditionally been volatile and is influenced by a combination of long-term, short-term and cyclical trends, including the domestic and international supply and demand for oil and natural gas, current and expected future prices for oil and natural gas and the perceived stability and sustainability of those prices, production depletion rates and the resultant levels of cash flows generated and allocated by exploration and production companies to their drilling, completion and related services and products budget. The oil and natural gas industry is also impacted by general domestic and international economic conditions, political instability in oil producing countries, government regulations (both in the United States and elsewhere), levels of customer demand, the availability of pipeline capacity and other conditions and factors that are beyond our control.

Demand for most of our oil and natural gas products and services depends substantially on the level of expenditures by companies in the oil and natural gas industry. The levels of capital expenditures of our customers are predominantly driven by the oil and natural gas prices. Over the past several years, commodity prices, particularly oil, has seen significant volatility with pricing ranging from a high of $110.53 per barrel on September 6, 2013 to a low of $26.19 per barrel on February 11, 2016. During early 2017, oil prices stabilized around the $50 per barrel level and started a gradual upward trend which continued into the third quarter of 2018, where oil prices averaged $69.60.

We anticipate demand for our oil and natural gas services and products will continue to be dependent on the level of expenditures by companies in the oil and natural gas industry and, ultimately, commodity prices. If commodity prices stabilize at current levels or continue to increase, we expect the capital expenditures of our customers to increase, which in turn should increase demand for our services and products, particularly in our completion and production, natural sand proppant and contract land and directional drilling businesses. Decreases in commodity prices, however, may result in a reduction in the capital expenditures of our customers and impact the demand for our drilling, completion and other products and services.

We expect the temporary challenges related to customer budget limitations to persist through the end of the year. Based on current feedback from customers, we expect exploration and production companies to take extended breaks in the fourth quarter of 2018 as a result of budget exhaustion.  We anticipate that these extended breaks will reduce activity levels and pricing for our services in the fourth quarter of 2018. We will continue to adjust our cost structure to market conditions, but we do not believe it is necessary to significantly reduce costs or infrastructure for a temporary slowdown in activity levels and we are actively maintaining our equipment during this temporary slowdown in activity levels. In 2019, we expect a rebound in activity from second half of 2018 levels as customer budgets are refreshed.

Energy Infrastructure Industry
    
In 2017, we expanded into the electric infrastructure business, offering both commercial and storm restoration services to government-funded utilities, private utilities, public investor owned utilities and cooperatives. Since we commenced operations in this line of business, substantially all of our infrastructure revenues has been generated from storm restoration work, primarily from PREPA due to damage caused by Hurricane Maria. On October 19, 2017, Cobra and PREPA entered into an emergency master services agreement for repairs to PREPA’s electrical grid. The one-year contract, as amended, provides for payments of up to $945.4 million. On May 26, 2018, Cobra and PREPA entered into a new one-year, $900.0 million master

32


services agreement to provide additional repair services and begin the initial phase of reconstruction of the electrical power system in Puerto Rico. PREPA is currently subject to bankruptcy proceedings pending in the U.S. District Court for the District of Puerto Rico. As a result, PREPA's ability to meet its payment obligations under the contract will be largely dependent upon funding from the Federal Emergency Management Agency or other sources. In the event PREPA does not have or does not obtain the funds necessary to satisfy its obligations to Cobra under the contracts, terminates the contracts, curtails our services prior to the end of the contract terms or otherwise fails to pay amounts owed to us for services performed, our financial condition, results of operations and cash flows would be materially and adversely affected. In addition, government contracts are subject to various uncertainties, restrictions and regulations, including oversight audits by government representatives and profit and cost controls, which could result in withholding or delayed payments to us or efforts to recover payments already made.

The demand for our infrastructure services in the continental United States has increased since we expanded into the infrastructure business. Our infrastructure teams are working for multiple utilities primarily across the northeastern, midwestern and southwestern portions of the United States. We believe we will be able to continue to grow our customer base in the continental United States and increase the backlog of work over the coming years. In Puerto Rico, the reconstruction process is just beginning with significant front-end engineering required prior to the reconstruction of the electric grid. Staffing levels in Puerto Rico have fluctuated between 500 and 600 people over the past 60 days and we anticipate a ramp up in reconstruction projects throughout 2019.

Natural Sand Proppant Industry

In the natural sand proppant industry, demand growth for frac sand and other proppants is primarily driven by advancements in oil and natural gas drilling and well completion technology and techniques, such as horizontal drilling and hydraulic fracturing, as well as overall industry activity growth. Demand for proppant declined in 2015 and throughout most of 2016 with reduced well completion activity; however, we believe that demand for proppant will continue to grow over the long-term, as it did throughout 2017 and the first half of 2018. Over the past 18 months, several new and existing suppliers announced planned capacity additions of frac sand supply, particularly in the Permian Basin. We expect frac sand supply to exceed growth in demand over the coming months and quarters. While planned capacity may exceed the expectations for frac sand demand, the collectively available industry capacity is constrained due to (i) availability of the grades of sand that are currently in demand, (ii) general operating conditions and normal downtime and (iii) logistics constraints. The industry is expected to add significant capacity over the next 12 to 18 months, particularly in the Permian Basin. We believe that the coarseness, conductivity, sphericity, acid-solubility and crush-resistant properties of our Northern White sand reserves and our transportation infrastructure afford us an advantage over many of our competitors and make us one of a select group of sand producers capable of delivering high volumes of frac sand that is optimal for oil and natural gas production to all major unconventional resource basins currently producing throughout North America.

During the first half of 2018, constraints in the rail system adversely impacted frac sand deliveries from our Taylor sand facility in Jackson County, Wisconsin. As a result, we estimate production at our Taylor facility was 23% lower during the first half of 2018 than it would have been in the absence of these constraints. These rail system constraints were largely alleviated during the third quarter of 2018. Production at our Piranha facility was not impacted by these rail constraints, however, another railroad recently instituted a policy that shifts from utilizing unit trains (100 car dedicated trains specifically set up to move sand in large quantities) to manifest shipments (smaller number of sand cars coupled with other types of loads to make up a full train shipment). This shift to manifest shipments could impede the ability to move sand from our Piranha facility.

Revenue. Revenue for the three months ended September 30, 2018 increased $235 million, or 157%, to $384 million from $149 million for the three months ended September 30, 2017. The increase in total revenue is primarily attributable to a $224 million increase in infrastructure services revenue during the three months ended September 30, 2018, representing 95% of the overall increase.

Revenue derived from related parties was $23 million, or 6% of our total revenues, for the three months ended September 30, 2018 and $71 million, or 47% of our total revenue, for the three months ended September 30, 2017. Substantially all of our related party revenue is derived from Gulfport under pressure pumping and sand contracts. Revenue by operating division was as follows:

34



Pressure Pumping Services. Pressure pumping services division revenue increased $15 million, or 21%, to $92 million for the three months ended September 30, 2018 from $77 million for the three months ended September 30, 2017. Revenue derived from related parties was $16 million, or 17% of total pressure pumping revenue, for the three months ended September 30, 2018 compared to $47 million, or 61% of total pressure pumping revenue, for the three months ended September 30, 2017. Substantially all of our related party revenue is derived from Gulfport. Inter-segment revenue, consisting primarily of revenue derived from our sand segment, totaled $1 million for each of the three months ended September 30, 2018 and 2017.

The increase in our pressure pumping services revenue was primarily driven by the startup of our fourth, fifth and sixth pressure pumping fleets in June, August and October 2017, respectively, in the SCOOP/STACK and Permian Basin, which contributed revenue of $34 million during the three months ended September 30, 2018 compared to $25 million during the three months ended September 30, 2017. The number of stages completed decreased slightly to 1,594 for the three months ended September 30, 2018 compared to 1,617 for the three months ended September 30, 2017 primarily due to a decline in utilization.

Infrastructure Services. Infrastructure services division revenue increased $224 million to $237 million for the three months ended September 30, 2018 from $13 million for the three months ended September 30, 2017. We generated $220 million, or 93% of total infrastructure services revenue, from our contract with PREPA for repairs to Puerto Rico's electrical grid as a result of Hurricane Maria. For additional information regarding our contracts with PREPA and our infrastructure services, see "Industry Overview - Electrical Infrastructure Industry" above.

Natural Sand Proppant Services. Natural sand proppant services division revenue increased $4 million, or 13%, to $37 million for the three months ended September 30, 2018, from $33 million for the three months ended September 30, 2017. Revenue derived from related parties was $4 million, or 10% of total sand revenue, for the three months ended September 30, 2018 and $14 million, or 43% of total sand revenue, for the three months ended September 30, 2017. Inter-segment revenue, consisting primarily of revenue derived from our pressure pumping segment, totaled $18 million, or 49% of total sand revenue, for the three months ended September 30, 2018 and $3 million, or 10% of total sand revenue, for the three months ended September 30, 2017.

The increase in our natural sand proppant services revenue was primarily attributable to a 26% increase in tons of sand sold from approximately 474,933 tons for the three months ended September 30, 2017 to 598,438 tons for the three months ended September 30, 2018, which was partially offset by a 10% decline in price per ton.

Contract Land and Directional Drilling Services. Contract land and directional drilling services division revenue increased $2 million, or 17%, from $14 million for the three months ended September 30, 2017 to $16 million for the three months ended September 30, 2018. Revenue derived from related parties, consisting of directional drilling revenue from Gulfport and El Toro Resources LLC, or El Toro, was $1 million, or 3% of total drilling revenue, for the three months ended September 30, 2018 and $1 million, or 8% of total drilling revenue, for the three months ended September 30, 2017.

The increase in contract land and directional drilling revenue was primarily attributable to our directional drilling services, which accounted for $2 million, or 105% of the total increase, as a result of increased utilization from 32% for the three months ended September 30, 2017 to 45% for the three months ended September 30, 2018. Our rig moving services accounted for $0.4 million, or 17%, of the operating division increase, primarily due to increased activity. These increases were partially offset by a $1 million decrease in our land drilling services revenue as a result of a decline in average active rigs from five for the three months ended September 30, 2017 to four for the three months ended September 30, 2018, partially offset by an increase in average day rates from approximately $14,800 for the three months ended September 30, 2017 to approximately $17,170 for the three months ended September 30, 2018.

Other Services. Other revenue, consisting of revenue derived from our coil tubing, pressure control, flowback, cementing, acidizing, equipment rental, crude oil hauling, water transfer and remote accommodation businesses, increased $5 million, or 24%, to $22 million for the three months ended September 30, 2018 from $17 million for the three months ended September 30, 2017. Revenue derived from related parties, consisting primarily of equipment rental and cementing revenue from Gulfport, was $3 million, or 13% of total other revenue, for the three months ended September 30, 2018 and $9 million, or 52% of total other revenue, for the three months ended September 30, 2017. Inter-segment revenue, consisting primarily of revenue derived from our infrastructure and

35


pressure pumping segments, totaled $1 million and $0.3 million, respectively, for the three months ended September 30, 2018 and 2017.

During the second quarter of 2018, we acquired RTS Energy Services LLC, or RTS, a cementing and acidizing business, and WTL Oil LLC, or WTL, a crude oil hauling business. These businesses contributed revenue of $7 million during the three months ended September 30, 2018. During the three months ended September 30, 2018, we started a water transfer business in the mid-continent region, which generated $2 million in revenue. Revenue from our coil tubing, oilfield rental and other services decreased $4 million during three months ended September 30, 2018 compared to three months ended September 30, 2017 primarily due to declines in utilization.

Cost of Revenue (exclusive of depreciation, depletion, amortization and accretion expense). Cost of revenue, exclusive of depreciation, depletion, amortization and accretion expense, increased $133 million from $115 million, or 77% of total revenue, for the three months ended September 30, 2017 to $248 million, or 64% of total revenue, for the three months ended September 30, 2018. The increase was primarily due to an expansion of our infrastructure services business, which represented a $118 million increase in cost of revenue, as well as an increase in pressure pumping division costs of $16 million, primarily related to the addition of three new fleets in 2017. Cost of revenue by operating division was as follows:

Pressure Pumping Services. Pressure pumping services division cost of revenue, exclusive of depreciation and amortization expense, increased $16 million, or 29%, to $73 million for the three months ended September 30, 2018 from $57 million for the three months ended September 30, 2017. The increase was primarily due to the expansion of services into the SCOOP/STACK and the Permian Basin with the addition of three fleets in 2017. As a percentage of revenue, our pressure pumping services division cost of revenue, exclusive of depreciation and amortization expense of $13 million for each of the three months ended September 30, 2018 and 2017, respectively, was 79% and 74% for the three months ended September 30, 2018 and 2017, respectively. The increase in costs as a percentage of revenue was primarily due to an increase in cost of goods sold as a result of selling sand with our service package to customers in the mid-continent region.

Infrastructure Services. Infrastructure services division cost of revenue, exclusive of depreciation and amortization expense, was $128 million and $10 million, respectively, for the three months ended September 30, 2018 and 2017. The increase is due to the expansion of our infrastructure business in late 2017 and 2018. The largest components of our cost of revenue include labor-related costs, including contract labor, and travel, meals and lodging expense. As a percentage of revenue, cost of revenue, exclusive of depreciation and amortization expense of $7 million and $1 million for the three months ended September 30, 2018 and 2017, respectively, was 54% and 75% for the three months ended September 30, 2018 and 2017, respectively.

Natural Sand Proppant Services. Natural sand proppant services division cost of revenue, exclusive of depreciation, depletion and accretion expense, increased $4 million, or 15%, from $26 million for the three months ended September 30, 2017 to $30 million for the three months ended September 30, 2018, primarily due to an increase in cost of goods sold as a result of a 26% increase in tons of sand sold in the 2018 period. As a percentage of revenue, cost of revenue, exclusive of depreciation, depletion and accretion expense of $4 million and $3 million for the three months ended September 30, 2018 and 2017, respectively, was 81% and 80% for the three months ended September 30, 2018 and 2017, respectively.

Contract Land and Directional Drilling Services. Contract land and directional drilling services division cost of revenue, exclusive of depreciation expense, increased $2 million, or 22%, from $12 million for the three months ended September 30, 2017 to $14 million for the three months ended September 30, 2018, primarily due to an increase in directional drilling utilization. As a percentage of revenue, our contract land and directional drilling services division cost of revenue, exclusive of depreciation expense of $4 million and $5 million for the three months ended September 30, 2018 and 2017, respectively, was 89% and 85% for the three months ended September 30, 2018 and September 30, 2017, respectively.

Other Services. Other services division cost of revenue, exclusive of depreciation and amortization expense, increased $7 million, or 50%, from $15 million for the three months ended September 30, 2017 to $22 million for the three months ended September 30, 2018, primarily due to the acquisition of RTS and WTL in the second quarter of 2018. As a percentage of revenue, cost of revenue, exclusive of depreciation and amortization expense of $4 million and $5 million for the three months ended September 30, 2018 and 2017, respectively, was 102% and 84% for the three months ended September 30, 2018 and 2017, respectively. The increase is primarily the result of start-up costs related to RTS, WTL and water transfer business in the mid-continent region as well as an increase in labor-related costs as a percentage of revenue.

Selling, General and Administrative Expenses. Selling, general and administrative expenses, or SG&A, represent the costs associated with managing and supporting our operations. During the three months ended September 30, 2018, we recognized a $68 million credit related to the provision for bad debt. Cash SG&A expense increased $15 million primarily related to costs incurred for the expansion of our infrastructure business. Following is a breakout of SG&A expenses for the periods indicated (in thousands):

b.
During the three months ended September 30, 2018, the Company received payment for amounts previously reserved in 2017. As a result, during the three months ended September 30, 2018, the Company reversed bad debt expense of $16.0 million recognized in 2017 and $53.6 million recognized in the first half of 2018. The Company expects to receive payment for the 2018 amounts once the Company files its 2018 Puerto Rico tax return and pays any taxes due as calculated by the return. The Company expects that the Puerto Rico 2018 tax return will be filed in mid-2019.

Depreciation, Depletion, Amortization and Accretion. Depreciation, depletion, amortization and accretion increased $5 million, or 18%, to $32 million for the three months ended September 30, 2018 from $27 million for the three months ended September 30, 2017. The increase is primarily attributable to an increase in property and equipment as a result of purchases in the second half of 2017 and in 2018, resulting in increased depreciation expense.

Impairment of Long-Lived Assets. We recorded an impairment of $5 million on various intangible assets during three months ended September 30, 2018 related to the movement of certain cementing equipment from the Utica shale to the Permian basin.
    
Operating Income (Loss). Operating income increased $146 million to $145 million for the three months ended September 30, 2018 compared to an operating loss of $0.5 million for the three months ended September 30, 2017. The increase was the result of the expansion of our infrastructure services business, which recognized an increase in operating income of $155 million. This increase was partially offset by a $7 million decrease in operating income for our other services, which was primarily due to impairment expense recognized during the three months ended September 30, 2018.

Interest Expense, Net. Interest expense, net decreased $1 million during the three months ended September 30, 2018 compared to the three months ended September 30, 2017 primarily due to a decline in average borrowings outstanding.

Other Expense, Net. Non-operating charges, net resulted in expense of $0.4 million and $0.3 million for the three months ended September 30, 2018 and 2017, respectively. Both periods were primarily comprised of loss recognition on assets disposed of during the periods.

Income Taxes. We recorded income tax expense of $75 million on pre-tax income of $144 million for the three months ended September 30, 2018 compared to an income tax benefit of $1 million on pre-tax loss of $2 million for the three months ended September 30, 2017. Our effective tax rate was 52% for the three months ended September 30, 2018 compared to 40% for the three months ended September 30, 2017. The increase in effective tax rate is primarily due to a higher tax rate in Puerto Rico, where most of our income was generated during the three months ended September 30, 2018, compared to the United States federal income tax rate as well as the impact of discrete items, state income taxes and permanent differences. No income was generated in Puerto Rico during the three months ended September 30, 2017.

Revenue. Revenue for the nine months ended September 30, 2018 increased $1.1 billion, or 338%, to $1.4 billion from $323 million for the nine months ended September 30, 2017. The increase in total revenue is primarily attributable to a $908 million increase in infrastructure services revenue, representing 83% of the overall increase. Additionally, pressure pumping services revenue increased $128 million, representing 12% of the overall increase.

Revenue derived from related parties was $134 million, or 9% of our total revenue, for the nine months ended September 30, 2018 and $174 million, or 54% of our total revenue, for the nine months ended September 30, 2017.

38


Substantially all of our related party revenue is derived from Gulfport under pressure pumping and sand contracts. Revenue by operating division was as follows:

Pressure Pumping Services. Pressure pumping services division revenue increased $128 million, or 76%, to $295 million for the nine months ended September 30, 2018 from $167 million for the nine months ended September 30, 2017. Revenue derived from related parties was $88 million, or 30% of total pressure pumping revenue, for the nine months ended September 30, 2018 compared to $120 million, or 71% of total pressure pumping revenue, for the nine months ended September 30, 2017. Substantially all of our related party revenue is derived from Gulfport. Inter-segment revenues, consisting primarily of revenue derived from our sand segment, totaled $6 million and $1 million for the nine months ended September 30, 2018 and 2017, respectively.

The increase in our pressure pumping services revenue was primarily driven by the startup of our fourth, fifth and sixth pressure pumping fleets in June, August and October 2017, respectively, in the SCOOP/STACK and the Permian Basin, which contributed revenue of $126 million during the nine months ended September 30, 2018 compared to $29 million during the nine months ended September 30, 2017. Additionally, the number of stages completed increased to 5,081 for the nine months ended September 30, 2018 from 3,764 for the nine months ended September 30, 2017.

Infrastructure Services. Infrastructure services division revenue increased $908 million from $15 million for the nine months ended September 30, 2017 to $923 million for the nine months ended September 30, 2018. We generated $885 million, or 96% of total infrastructure services revenue, from our contract with PREPA for repairs to Puerto Rico's electrical grid as a result of Hurricane Maria. For additional information regarding our contracts with PREPA and our infrastructure services, see "Industry Overview - Electrical Infrastructure Industry" above.

Natural Sand Proppant Services. Natural sand proppant services division revenue increased $68 million, or 93%, to $141 million for the nine months ended September 30, 2018, from $73 million for the nine months ended September 30, 2017. Revenue derived from related parties was $25 million, or 18% of total sand revenue, for the nine months ended September 30, 2018 and $39 million, or 54% of total sand revenue, for the nine months ended September 30, 2017. Inter-segment revenue, consisting primarily of revenue derived from our pressure pumping segment, totaled $48 million, or 34% of total sand revenue, for the nine months ended September 30, 2018 and $5 million, or 7% of total sand revenue, for the nine months ended September 30, 2017.

The increase in our natural sand proppant services revenue was primarily attributable to a 94% increase in tons of sand sold from approximately 1,089,851 tons for the nine months ended September 30, 2017 to 2,111,872 tons for the nine months ended September 30, 2018. We completed the expansion of our Taylor and Piranha sand facilities in March and August 2018, respectively. In May 2017, we acquired a wet and dry plant and sand mine located on approximately 600 acres in New Auburn, Wisconsin through our purchase of the assets of Chieftain. These assets contributed revenue of $35 million to our natural sand proppant division for the nine months ended September 30, 2018 compared to $4 million for the nine months ended September 30, 2017.

Contract Land and Directional Drilling Services. Contract land and directional drilling services division revenue increased $11 million, or 31%, from $37 million for the nine months ended September 30, 2017 to $48 million for the nine months ended September 30, 2018. Revenue derived from related parties, consisting primarily of directional drilling revenue from Gulfport and El Toro, was $1 million, or 2% of total drilling revenue, for the nine months ended September 30, 2018 compared to $3 million, or 8% of total drilling revenue, for the nine months ended September 30, 2017.

The increase in contract land and directional drilling revenue was primarily attributable to our directional drilling services, which accounted for $8 million, or 69% of the total increase, as a result of increased utilization from 28% for the nine months ended September 30, 2017 to 45% for the nine months ended September 30, 2018. Our rig moving services accounted for $3 million, or 22%, of the operating division increase, primarily due to increased activity. Our land drilling services accounted for $1 million, or 7%, of the operating division increase, as a result of an increase in average day rates from approximately $14,433 for the nine months ended September 30, 2017 to approximately $16,980 for the nine months ended September 30, 2018, partially offset by a decrease in average active rigs from five for the nine months ended September 30, 2017 to four rigs for the nine months ended September 30, 2018.


39


Other Services. Other revenue, consisting of revenue derived from our coil tubing, pressure control, flowback, cementing, acidizing, equipment rental, crude oil hauling, water transfer and remote accommodation businesses, increased $28 million, or 77%, to $65 million for the nine months ended September 30, 2018 from $37 million for the nine months ended September 30, 2017. Revenue derived from related parties, consisting primarily of equipment rental and cementing revenue from Gulfport, was $20 million, or 31% of total other revenue, for the nine months ended September 30, 2018 and $12 million, or 32% of total other revenue, for the nine months ended September 30, 2017. Inter-segment revenue, consisting primarily of revenue derived from our infrastructure and pressure pumping segments, totaled $5 million and $0.4 million for the nine months ended September 30, 2018 and 2017, respectively.

Revenue for Stingray Cementing and Stingray Energy, which we acquired in June 2017, increased $16 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. During the second quarter of 2018, we acquired RTS, a cementing and acidizing business, and WTL, a crude oil hauling business. These business contributed revenue of $8 million during the nine months ended September 30, 2018. Revenue from our coil tubing, pressure control and flowback services increased $7 million for the nine months ended September 30, 2018 compared to nine months ended September 30, 2017 primarily due to increases in utilization. These increases were partially offset by a decrease in revenue from our remote accommodations business due to a decline in utilization.

Cost of Revenue (exclusive of depreciation, depletion, amortization and accretion expense). Cost of revenue, exclusive of depreciation, depletion, amortization and accretion expense, increased $663 million from $250 million, or 78% of total revenue, for the nine months ended September 30, 2017 to $913 million, or 65% of total revenue, for the nine months ended September 30, 2018. The increase was primarily due to the expansion of our infrastructure services business, which represented a $523 million increase in cost of revenue, as well as an increase in pressure pumping division costs of $110 million, primarily related to the addition of three new fleets during 2017, and an increase in natural sand proppant division costs of $45 million, primarily due to an increase in tons of sand sold during the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. Cost of revenue by operating division was as follows:

Pressure Pumping Services. Pressure pumping services division cost of revenue, exclusive of depreciation and amortization expense, increased $110 million, or 90%, to $233 million for the nine months ended September 30, 2018 from $123 million for the nine months ended September 30, 2017. The increase was primarily due to the expansion of services into the SCOOP/STACK and the Permian Basin with the addition of three fleets during 2017, which accounted for $85 million, or 77%, of the increase. As a percentage of revenue, our pressure pumping services division cost of revenue, exclusive of depreciation and amortization expense of $40 million and $32 million for the nine months ended September 30, 2018 and 2017, respectively, was 79% and 73% for the nine months ended September 30, 2018 and September 30, 2017, respectively. The increase in costs as a percentage of revenue was primarily due to an increase in cost of goods sold as a result of selling sand with our service package to customers in the mid-continent region.

Infrastructure Services. Infrastructure services division cost of revenue, exclusive of depreciation and amortization expense, was $535 million and $12 million for the nine months ended September 30, 2018 and 2017, respectively. The increase is due to the expansion of our infrastructure business in late 2017 and 2018. The largest components of our cost of revenue include labor-related costs, including contract labor, and travel, meals and lodging expense. As a percentage of revenue, cost of revenue, exclusive of depreciation and amortization expense of $13 million and $1 million for the nine months ended September 30, 2018 and 2017, respectively, was 58% and 78% for the nine months ended September 30, 2018 and 2017, respectively.

Natural Sand Proppant Services. Natural sand proppant services division cost of revenue, exclusive of depreciation, depletion and accretion expense, increased $45 million, or 76%, from $59 million for the nine months ended September 30, 2017 to $104 million for the nine months ended September 30, 2018, primarily due to an increase in cost of goods sold as a result of a 94% increase in tons of sand sold in the 2018 period as compared to the same period in 2017. As a percentage of revenue, cost of revenue, exclusive of depreciation, depletion and accretion expense of $10 million and $7 million for the nine months ended September 30, 2018 and 2017, respectively, was 74% and 81% for the nine months ended September 30, 2018 and September 30, 2017, respectively. The decrease is primarily due to startup costs incurred for our Piranha plant, which we acquired in May 2017.

Contract Land and Directional Drilling Services. Contract land and directional drilling services division cost of revenue, exclusive of depreciation expense, increased $9 million, or 27%, from $35 million for the nine months ended September 30, 2017 to $44 million for the nine months ended September 30, 2018, primarily due to increased

40


utilization. As a percentage of revenue, our contract land and directional drilling services division cost of revenue, exclusive of depreciation expense of $14 million and $15 million for the nine months ended September 30, 2018 and 2017, respectively, was 91% and 94% for the nine months ended September 30, 2018 and September 30, 2017, respectively. The decrease was primarily due to higher day rates.

Other Services. Other services division cost of revenue, exclusive of depreciation and amortization expense, increased $28 million, or 100%, from $29 million for the nine months ended September 30, 2017 to $57 million for the nine months ended September 30, 2018, primarily due to the acquisition of Stingray Cementing and Stingray Energy in June 2017 and the acquisitions of RTS and WTL in the second quarter of 2018. As a percentage of revenue, cost of revenue, exclusive of depreciation and amortization expense of $12 million and $10 million for the nine months ended September 30, 2018 and 2017, respectively, was 89% and 79% for the nine months ended September 30, 2018 and 2017, respectively. The increase is primarily the result of start-up costs related to RTS, WTL and the water transfer business in the mid-continent region as well as an increase in equipment rental expense as a percentage of revenue.

Selling, General and Administrative Expenses. Selling, general and administrative expenses represent the costs associated with managing and supporting our operations. These expenses increased $36 million to $58 million for the nine months ended September 30, 2018, from $22 million for the nine months ended September 30, 2017, primarily related to costs incurred for the expansion of our infrastructure business and the recognition of equity based compensation. The equity based compensation represents compensation expense for awards issued by certain Wexford affiliates and had no cash impact to the Company and no dilutive impact relative to the number of shares outstanding.

a.
Includes travel-related costs, IT expenses, rent, utilities and other general and administrative-related costs.
b.
During the three months ended September 30, 2018, the Company received payment for amounts previously reserved in 2017. As a result, during the three months ended September 30, 2018, the Company reversed bad debt expense of $16.0 million recognized in 2017.
c.
Represents compensation expense for non-employee awards, which were issued and are payable by certain affiliates of Wexford (the sponsor level).

Depreciation, Depletion, Amortization and Accretion. Depreciation, depletion, amortization and accretion increased $26 million, or 39%, to $90 million for the nine months ended September 30, 2018 from $64 million for the nine months ended September 30, 2017. The increase is primarily attributable to an increase in property and equipment purchases in the second half of 2017 and 2018, resulting in increased depreciation expense.

Impairment of Long-Lived Assets. We recorded an impairment of $5 million on various intangible assets during the nine months ended September 30, 2018 related to the movement of certain cementing equipment from the Utica shale to the Permian basin.
    
Operating Income (Loss). Operating income increased $361 million to $346 million for the nine months ended September 30, 2018 compared to an operating loss of $15 million for the nine months ended September 30, 2017. The increase was primarily the result of an expansion of our infrastructure services business, which accounted for $356 million of the increase in operating income and a $21 million increase in natural sand proppant operating income. These were partially offset

41


by a $12 million decrease in pressure pumping operating income due to an increase in non-cash equity compensation expense during the nine months ended September 30, 2018.

Interest Expense, Net. Interest expense, net was $3 million for each of the nine months ended September 30, 2018 and 2017. Average outstanding borrowings remained relatively flat for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017.

Other Expense, Net. Non-operating charges, net resulted in expense of $1 million for each of the nine months ended September 30, 2018 and 2017. Both periods were primarily comprised of loss recognition on assets disposed of during the period.

Income Taxes. We recorded income tax expense of $174 million on pre-tax income of $342 million for the nine months ended September 30, 2018 compared to an income tax benefit of $7 million on pre-tax loss of $14 million for the nine months ended September 30, 2017. Our effective tax rate was 51% for the nine months ended September 30, 2018 compared to 37% for the nine months ended September 30, 2017. The increase in effective tax rate is primarily due to the equity based compensation expense recognized during the nine months ended September 30, 2018 as well as a higher tax rate in Puerto Rico, where most of our income was generated during the nine months ended September 30, 2018, compared to the United States federal income tax rate. No income was generated in Puerto Rico during the nine months ended September 30, 2017.

Non-GAAP Financial Measures

Adjusted EBITDA

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDA as net income (loss) before depreciation, depletion, accretion and amortization, impairment of long-lived assets, acquisition related costs, public offering costs, equity based compensation, stock based compensation, bargain purchase gain, interest expense, net, other expense, net (which is comprised of the (gain) or loss on disposal of long-lived assets) and provision (benefit) for income taxes. We exclude the items listed above from net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industries 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 our 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. Our computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. We believe that Adjusted EBITDA is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet debt service requirements.

Adjusted Net Income and Adjusted Earnings per Share

Adjusted net income and adjusted basic and diluted earnings per share are supplemental non-GAAP financial measures that are used by management to evaluate our operating and financial performance. Management believes these measures provide meaningful information about the Company's performance by excluding certain non-cash charges, 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.

Liquidity and Capital Resources

We require capital to fund ongoing operations, including maintenance expenditures on our existing fleet of equipment, organic growth initiatives, investments and acquisitions. Since November 2014, our primary sources of liquidity have been cash on hand, borrowings under our revolving credit facility, cash flows from operations and proceeds from our initial public offering. Our primary uses of capital have been for investing in property and equipment used to provide our services and to acquire complementary businesses. In addition, on July 16, 2018, we initiated a quarterly dividend policy and declared our first quarterly cash dividend, which was paid in August 2018. On October 29, 2018, our Board of Directors declared a quarterly cash dividend of $0.125 per common share payable on November 15, 2018 to stockholders of record on November 8, 2018. Future declaration of cash dividends are subject to approval by our Board of Directors and may be adjusted at its discretion based on market conditions and capital availability.

As of September 30, 2018, we had no borrowings outstanding under our revolving credit facility and $162 million of available borrowing capacity under this facility, after giving effect to $7 million of outstanding letters of credit.

Net working capital (less cash) is a non-GAAP measure and is calculated by subtracting total current liabilities of $355 million and cash and cash equivalents of $20 million from total current assets of $467 million as of September 30, 2018. As of December 31, 2017, net working capital (less cash) is calculated by subtracting total current liabilities of $220 million and cash and cash equivalents of $6 million from total current assets of $314 million.

At October 30, 2018, we had no borrowings outstanding under our amended and restated revolving credit facility, leaving an aggregate of $177 million of available borrowing capacity under this facility, which is net of letters of credit of $7 million.

Operating Activities

Net cash provided by operating activities was $283 million for the nine months ended September 30, 2018, compared to $41 million for the nine months ended September 30, 2017. Net cash provided by operating activities was $56 million for the

46


three months ended September 30, 2018 compared to $17 million for the three months ended September 30, 2017. The increase in operating cash flows was primarily attributable to the increase in net income as a result of the expansion of our infrastructure services business and improvements in our pressure pumping and sand businesses.

Investing Activities
    
Net cash used in investing activities was $163 million for the nine months ended September 30, 2018, compared to $141 million for the nine months ended September 30, 2017. Net cash used in investing activities was $42 million for the three months ended September 30, 2018, compared to $38 million for the three months ended September 30, 2017. Cash used in investing activities was used to purchase property and equipment that is utilized to provide our services and to acquire complementary businesses.

Financing Activities

Net cash used in financing activities was $106 million for the nine months ended September 30, 2018, compared to net cash provided by financing activities of $85 million for the nine months ended September 30, 2017. Net cash used in financing activities was $6 million for the three months ended September 30, 2018, compared to net cash provided by financing activities of $27 million for the three months ended September 30, 2017. Net cash used in financing activities was primarily attributable to $6 million in dividends paid during the three and nine months ended September 30, 2018 and net repayments under our revolving credit facility of $100 million for the nine months ended September 30, 2018. Net cash provided by financing activities was primarily attributable to net borrowings under our revolving credit facility of $29 million and $94 million for the three and nine months ended September 30, 2017, respectively.

Effect of Foreign Exchange Rate on Cash

The effect of foreign exchange rate on cash was ($0.1) million and $0.1 million for the nine months ended September 30, 2018 and 2017, respectively. The change was driven primarily by a favorable (unfavorable) shift in the weakness (strength) of the Canadian dollar relative to the U.S. dollar for the cash held in Canadian accounts.

Working Capital

Our working capital totaled $111 million and $94 million at September 30, 2018 and December 31, 2017, respectively. Our cash balances were $20 million and $6 million at September 30, 2018 and December 31, 2017, respectively.

Our Revolving Credit Facility

On October 19, 2018, we and certain of our direct and indirect subsidiaries, as borrowers, entered into an amended and restated revolving credit and security agreement with the lenders party thereto and PNC Bank, National Association, as a lender

47


and as administrative agent for the lenders, which amends and restates our prior revolving credit and security agreement dated as of July 9, 2018, as amended prior to October 19, 2018, to, among other things, (i) extend the maturity date to October 19, 2023, (ii) increase the maximum revolving advance amount to $185 million, with the ability to further increase the maximum revolving advance amount to $350 million under certain circumstances, (iii) increase the letter of credit sublimit to 20% of the maximum revolving advance amount and (iv) decrease the interest rates applicable to loans.

Outstanding borrowings under this amended and restated revolving credit facility bear interest at a per annum rate elected by us that is equal to an alternate base rate or LIBOR, in each case plus the applicable margin. The applicable margin ranges from 1.00% to 1.50% per annum in the case of the alternate base rate, and from 2.00% to 2.50% per annum in the case of LIBOR. The applicable margin depends on the amount of excess availability under this amended and restated revolving credit facility.

At September 30, 2018, we had no outstanding borrowings under our then existing revolving credit facility. At October 30, 2018, we had availability of $177 million under our amended and restated revolving credit facility, after giving effect to $7 million of outstanding letters of credit.     

Our amended and restated revolving credit facility contains various customary affirmative and restrictive covenants. Among the covenants are two financial covenants, including a minimum interest coverage ratio (3.0 to 1.0), and a maximum leverage ratio (4.0 to 1.0), and minimum availability ($10.0 million). As of September 30, 2018 and December 31, 2017, we were in compliance with the financial covenants under our then existing revolving credit facility.

Capital Requirements and Sources of Liquidity

During 2018, we currently estimate that our aggregate capital expenditures will be approximately $205 million. These capital expenditures include $98 million in our infrastructure services segment for assets for additional crews, $25 million in our natural sand proppant services segment primarily related to expansion projects, $21 million in our pressure pumping segment for various pressure pumping equipment, $14 million in our contract land and directional drilling services segment primarily for rig upgrades and real estate, $17 million for expansion of our rental equipment business in Ohio and into Oklahoma, $10 million for the expansion of our water transfer business, $8 million for the expansion of our crude hauling business, $6 million for coil tubing equipment and $6 million for other capital expenditures. During the nine months ended September 30, 2018, our capital expenditures totaled $150 million.

We believe that our cash on hand, operating cash flow and available borrowings under our revolving credit facility will be sufficient to fund our operations for at least the next twelve months. However, future cash flows are subject to a number of variables, and significant additional capital expenditures could be required to conduct our operations. There can be no assurance that operations and other capital resources will provide cash in sufficient amounts to maintain planned or future levels of capital expenditures. Further, we continue to pursue our previously announced acquisition strategy to enhance our portfolio of products and services, market positioning and/or geographic presence in both other existing and new industries. In doing so, we regularly evaluate acquisition opportunities. However, we do not have a specific acquisition budget for 2018 since the timing and size of acquisitions cannot be accurately forecasted. Our acquisitions may be undertaken with cash, our common stock or a combination of cash, common stock and/or other consideration. In the event we make one or more additional acquisitions and the amount of capital required is greater than the amount we have available for acquisitions at that time, we could be required to reduce the expected level of capital expenditures and/or seek additional capital. If we seek additional capital for that or other reasons, we may do so through borrowings under our revolving credit facility, joint venture partnerships, asset sales, offerings of debt or equity securities or other means. We cannot assure you that this additional capital will be available on acceptable terms or at all. If we are unable to obtain funds we need, we may not be able to complete acquisitions that may be favorable to us or finance the capital expenditures necessary to conduct our operations.

Off-Balance Sheet Arrangements
Lease Obligations

We lease real estate, rail cars and other equipment under long-term operating leases with varying terms and expiration dates through 2062.

Minimum Purchase Commitments

We have entered into agreements with suppliers that contain minimum purchase obligations. Our failure to purchase the minimum amounts may require us to pay shortfall fees. However, the minimum quantities set forth in the agreements are not in excess of our currently expected future requirements.

Capital Spend Commitments

We have entered into agreements with suppliers to acquire capital equipment.

The minimum amount due in the form of shortfall fees under certain sand purchase agreements was $3.8 million as of September 30, 2018.

Other Commitments

Subsequent to September 30, 2018, a subsidiary in our infrastructure segment entered into an air charter agreement with aggregate commitments of $1.6 million and our pressure pumping subsidiary purchased additional equipment totaling $1.4 million.

Subsequent to September 30, 2018, we ordered additional capital equipment with aggregate commitments of $8.1 million.

New Accounting Pronouncements
In February 2016, the FASB issued ASU No, 2016-02 “Leases” amending the current accounting for leases. Under the new provisions, all lessees will report a right-of-use asset and a liability for the obligation to make payments for all leases with the exception of those leases with a term of 12 months or less.  All other leases will fall into one of two categories: (i) a financing lease or (ii) an operating lease. Lessor accounting remains substantially unchanged with the exception that no leases entered into after the effective date will be classified as leveraged leases. For sale leaseback transactions, a sale will only be recognized if the criteria in the new revenue recognition standard are met. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within that fiscal year. We plan to adopt this ASU effective January 1, 2019 utilizing the modified retrospective method of adoption. This new leasing guidance will impact us in situations where we are the lessee, and in certain circumstances we will have a right-of-use asset and lease liability on our consolidated financial statements. We are in the process of implementing a new lease accounting system in connection with the adoption of this ASU and are continuing to evaluate the impact this new guidance may have on our consolidated financial statements and results of operations.

In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Accounting,” which simplifies the accounting for share-based payments granted to non-employees by aligning the accounting with requirements for employee share-based compensation. Upon transition, this ASU requires non-employee awards to be measured at fair value as of the adoption date. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within that fiscal year. Early adoption is permitted. Currently, we have not elected to early adopt this ASU and are evaluating the impact it will have on our consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The demand, pricing and terms for our products and services are largely dependent upon the level of activity for the U.S. oil and natural gas industry, energy infrastructure industry and natural sand proppant industry. Industry conditions are influenced by numerous factors over which we have no control, including, but not limited to: the supply of and demand for oil and natural gas services, energy infrastructure services and natural sand proppant; the level of construction of transmission lines, substations and distribution networks in the energy infrastructure industry and the level of expenditures of utility companies; the level of prices of, and expectations about future prices for, oil and natural gas and natural sand proppant, as well as energy infrastructure services; the cost of exploring for, developing, producing and delivering oil and natural gas; the expected rates of declining current production; the discovery rates of new oil and natural gas reserves and frac sand reserves meeting industry specifications and consisting of the mesh size in demand; access to pipeline, transloading and other transportation facilities and their capacity; weather conditions; domestic and worldwide economic conditions; political instability in oil-producing countries; environmental regulations; technical advances affecting energy consumption; the price and availability of alternative fuels; the ability of oil and natural gas producers and other users of our services to raise equity capital and debt financing; and merger and divestiture activity in industries in which we operate.

The level of activity in the U.S. oil and natural gas exploration and production, energy infrastructure and natural sand proppant industries is volatile. Expected trends may not continue and demand for our products and services may not reflect the level of activity in these industries. Any prolonged substantial reduction in pricing environment would likely affect demand for our services. A material decline in pricing levels or U.S. activity levels could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Interest Rate Risk

We had a cash and cash equivalents balance of $20 million at September 30, 2018. We do not enter into investments for trading or speculative purposes. We do not believe that we have any material exposure to changes in the fair value of these investments as a result of changes in interest rates. Declines in interest rates, however, will reduce future income.

Interest under our credit facility is payable at a base rate plus an applicable margin. Additionally, at our request, outstanding balances are permitted to be converted to LIBOR rate plus applicable margin tranches. The applicable margin for either the base rate or the LIBOR rate option can vary from 1.5% to 3.0%, based upon a calculation of the excess availability of the line as a percentage of the maximum credit limit. At September 30, 2018, we had no outstanding borrowings under our revolving credit facility. As of July 31, 2018, the last day on which we had any material outstanding borrowings under our revolving credit facility, a 1% increase or decrease in the interest rate would have increased or decreased our interest expense by approximately $0.1 million per year, based on $6 million outstanding and a weighted average interest rate of 6.5%. We do not currently hedge our interest rate exposure.

Foreign Currency Risk

Our remote accommodation business, which is included in our other energy services segment, generates revenue and incurs expenses that are denominated in the Canadian dollar. These transactions could be materially affected by currency fluctuations. Changes in currency exchange rates could adversely affect our consolidated results of operations or financial position. We also maintain cash balances denominated in the Canadian dollar. At September 30, 2018, we had $2 million of cash, in Canadian dollars, in Canadian accounts. A 10% increase in the strength of the Canadian dollar versus the U.S. dollar would have resulted in an increase in pre-tax income of approximately $0.2 million as of September 30, 2018. Conversely, a corresponding decrease in the strength of the Canadian dollar would have resulted in a comparable decrease in pre-tax income. We have not hedged our exposure to changes in foreign currency exchange rates and, as a result, could incur unanticipated translation gains and losses.

Seasonality

We provide completion and production services as well as contract land and drilling services primarily in the Utica, Permian Basin, Eagle Ford, Marcellus, Granite Wash, Cana Woodford and Cleveland sand resource plays located in the continental U.S. We provide infrastructure services primarily in the northeast, southwest and midwest portions of the United States and in Puerto Rico. We provide remote accommodation services in the oil sands in Alberta, Canada. We serve these markets through our facilities and service centers that are strategically located to serve our customers in Ohio, Texas, Oklahoma, Wisconsin, Minnesota, Kentucky, Puerto Rico and Alberta, Canada. A portion of our revenues are generated in Ohio, Wisconsin, Minnesota, North Dakota, Pennsylvania, West Virginia and Canada where weather conditions may be severe.

51


As a result, our operations may be limited or disrupted, particularly during winter and spring months, in these geographic regions, which would have a material adverse effect on our financial condition and results of operations. Our operations in Oklahoma and Texas are generally not affected by seasonal weather conditions.

52


Item 4. Controls and Procedures

Evaluation of Disclosure Control and Procedures

Under the direction of our Chief Executive Officer and Chief Financial Officer, we have established disclosure controls and procedures, as defined in Rule 13a-15(e) and d under the Exchange Act, that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. The disclosure controls and procedures are also intended to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

As of September 30, 2018, an evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of September 30, 2018, our disclosure controls and procedures are effective.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) that occurred during the quarter ended September 30, 2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings

Due to the nature of our business, we are, from time to time, involved in litigation or subject to disputes or claims related to our business activities, including breaches of contractual obligations, workers’ compensation claims and employment related disputes. In the opinion of our management, none of the pending litigation, disputes or claims against us is expected to have a material adverse effect on our financial condition, cash flows or results of operations. See Note 18 "Commitments and Contingencies," of the Notes to Unaudited Condensed Consolidated Financial Statements for additional information.

Item 1A. Risk Factors

Security holders and potential investors in our securities should carefully consider the risk factors in our Annual Report on Form 10-K (Commission File No. 001-37917) filed with the SEC on February 28, 2018 and in our Rule 424(b)(5) prospectus summary and related base prospectus filed with the SEC on June 26, 2018. 

Other than set forth below, there have been no material changes to the Risk Factors previously disclosed in our Prospectus Summary dated July 26, 2018.

As of December 31, 2018, we will no longer be an “emerging growth company” and, as a result, we have begun incurring significant additional financial compliance costs by having to comply with increased disclosure and governance requirements.

We have generated over $1.07 billion in revenue throughout the first nine months of 2018. As a result, we will cease to be an emerging growth company as defined in the JOBS Act as of December 31, 2018. We will be an accelerated filer as of December 31, 2018 and will be subject to certain requirements that apply to other public companies, but did not previously apply to us due to our status as an emerging growth company. These requirements include:

the provisions of Section 404(b) of the Sarbanes-Oxley Act ("Section 404") requiring that our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting;

the requirement to provide detailed compensation discussion and analysis in proxy statements and reports filed under the Exchange Act; and

the "say on pay" provisions, which require a non-binding stockholder vote to approve compensation of certain executive officers, and the "say on golden parachute" provisions, which require a non-binding stockholder vote to approve golden parachute arrangements for certain executive officers in connection with mergers and certain other business combinations) of the Dodd-Frank Act.

We have already begun to incur additional compliance costs in connection with our forthcoming loss of emerging growth company status. We expect that our compliance with these additional requirements, including the provisions of Section 404, will continue to increase professional costs and require management to devote substantial time and effort toward ensuring compliance with these requirements.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Not applicable.

Item 4. Mine Safety Disclosures

Our operations are subject to the Federal Mine Safety and Health Act of 1977, as amended by the Mine Improvement and New Emergency Response Act of 2006, which imposes stringent health and safety standards on numerous aspects of mineral extraction and processing operations, including the training of personnel, operating procedures, operating equipment and other matters. Our failure to comply with such standards, or changes in such standards or the interpretation or enforcement thereof, could have a material adverse effect on our business and financial condition or otherwise impose significant restrictions on our ability to conduct mineral extraction and processing operations. Following passage of The Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the numbers of citations and orders charged against mining operations.  The dollar penalties assessed for citations issued has also increased in recent years.  Information concerning mine
