I am very proud of what the 
Mammoth team achieved 
throughout 2019.  
Our entire team stayed 
true to our principles to 
remain disciplined in our 
investments, take care of 
the balance sheet, look for 
opportunities to invest in 
areas that are stable and 
contract driven and keep  
costs low.

The events over the past several months have caused demand 

consolidation and several companies exiting the industry 

completely resulting in fewer pressure pumping companies. 

As a result, the industry has been more reactive to weakening 

demand and quicker to idle equipment, providing some 

support for margins.

GLOSSARY OF OIL AND NATURAL GAS AND ELECTRICAL INFRASTRUCTURE TERMS

The following is a glossary of certain oil and natural gas and natural sand proppant industry terms used in this report:

Acidizing

To pump acid into a wellbore to improve a well's productivity or injectivity.

Blowout

Bottomhole assembly

Cementing

Coiled tubing

Completion

Directional drilling

Down-hole

Down-hole motor

Drilling rig

Drillpipe or Drill pipe

Drillstring or Drill string

Flowback

Horizontal drilling

Hydraulic fracturing

Hydrocarbon

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.

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. 

To prepare and pump cement into place in a wellbore.

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.

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. 

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. 

Pertaining to or in the wellbore (as opposed to being on the surface).

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.

The machine used to drill a wellbore.

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. 

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.

The process of allowing fluids to flow from the well following a treatment, either in preparation for a subsequent 
phase of treatment or in preparation for cleanup and returning the well to production.

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.

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.

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

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.

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.

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.

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.

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.

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.

Tubulars

Unconventional resource

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.

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. 

Accumulation of hydrocarbons known to exist over a large area.

A fine-grained, fissile, sedimentary rock formed by consolidation of clay- and silt-sized particles into thin, relatively 
impermeable layers.

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.

A type of unconventional tight reservoir. Tight reservoirs are those which have low permeability, often quantified 
as less than 0.1 millidarcies.

A generic term pertaining to any type of oilfield pipe, such as drill pipe, drill collars, pup joints, casing, production 
tubing and pipeline.

A term for the different manner by which resources are exploited as compared to the extraction of conventional 
resources.  In  unconventional  drilling,  the  wellbore  is  generally  drilled  to  specific  objectives  within  narrow 
parameters, often across long, lateral intervals within narrow horizontal formations offering greater contact area 
with the producing formation. Typically, the well is then hydraulically fractured at multiple stages to optimize 
production.

Wellbore

The physical conduit from surface into the hydrocarbon reservoir.

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.

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.

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.

PART I.

The historical financial information for periods prior to October 12, 2016, contained in this annual report relates to Mammoth 
Energy Partners LP, a Delaware limited partnership, or the Partnership. On October 12, 2016, the Partnership was converted 
into a Delaware limited liability company named Mammoth Energy Partners LLC, or Mammoth LLC, and then each member of 
Mammoth LLC contributed all of its membership interests in Mammoth LLC to Mammoth Energy Services, Inc., a Delaware 
corporation, or 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) 
became a wholly-owned subsidiary of Mammoth Inc.

On October 13, 2016, Mammoth Inc. priced 7,750,000 shares of its common stock in its initial public offering, or the IPO, at a 
price to the public of $15.00 per share and, on October 14, 2016, Mammoth Inc.’s common stock began trading on The Nasdaq 
Global Select Market under the symbol “TUSK.” On October 19, 2016, Mammoth Inc. closed its IPO. Unless the context 
otherwise requires, references in this report to “we,” “our,” “us” or like terms, when used in a historical context for periods 
prior to October 12, 2016 refer to the Partnership and its subsidiaries. References in this report to “we,” “our,” “us” or like 
terms, when used for periods beginning on or after October 12, 2016 refer to Mammoth Inc. and its subsidiaries. 

On June 5, 2017, we acquired Sturgeon Acquisitions LLC, or Sturgeon, and Sturgeon's wholly owned subsidiaries Taylor Frac, 
LLC, or Taylor Frac, Taylor Real Estate Investments, LLC, or Taylor Real Estate, and South River Road, LLC, or South River 
Road. 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 included in this Annual Report 
on Form 10-K has been recast to combine Sturgeon's financial results with our financial results as if the acquisition had been 
effective since Sturgeon commenced operations.

Item 1. Business

Overview

We are an integrated, growth-oriented company serving both the electric utility and oil and gas industries in North 

America. Our primary business objective is to grow our operations and create value for stockholders through organic growth 
opportunities and accretive acquisitions. Our suite of services includes infrastructure services, pressure pumping services, 
natural sand proppant services, drilling services and other services, which includes coil tubing, equipment rental, full service 
transportation, crude oil hauling, remote accommodations, oilfield equipment manufacturing and infrastructure engineering and 
design services. Our infrastructure services division provides construction, upgrade, maintenance and repair services to the 
electrical infrastructure industry. Our pressure pumping services division provides hydraulic fracturing, sand hauling and water 
transfer services. Our natural sand proppant services division mines, processes and sells natural sand proppant used for 
hydraulic fracturing. Our drilling services division currently provides rental equipment, such as mud motors and operational 
tools, for both vertical and horizontal drilling as well as rig moving services. In addition to these service divisions, we also 
provide coil tubing services, pressure control services, equipment rentals, full service transportation, crude oil hauling services, 
remote accommodations, oilfield equipment manufacturing and infrastructure engineering and design services. We believe that 
the services we offer play a critical role in maintaining and improving electrical infrastructure as well as in increasing the 
ultimate recovery and present value of production streams from unconventional resources. Our complementary suite of services 
provides us with the opportunity to cross-sell our services and expand our customer base and geographic positioning. 

Our transformation towards an industrial based company is ongoing. During the fourth quarter of 2019, we began 

infrastructure engineering operations focused on the transmission and distribution industry and also commenced oilfield 
equipment manufacturing operations. The startup of oilfield equipment manufacturing operations provides us with the ability to 
repair much of our existing equipment in-house, as well as the option to manufacture certain new equipment we may need in 
the future. The oilfield equipment manufacturing operations will initially serve our internal needs for our water transfer and 
equipment rental businesses, but we expect to expand into third party sales in the future. We are continuing to explore other 
opportunities to expand our business lines as we shift to a broader industrial focus.

Our facilities and service centers are strategically located in Ohio, Texas, Oklahoma, Wisconsin, Minnesota, West 

Virginia, Kentucky, California, Colorado, Florida and Alberta, Canada primarily to serve the following areas:

•  The Utica Shale in Eastern Ohio;
• 

Southern Ohio;

1

 
 
 
 
•  The Permian Basin in West Texas;
•  The Appalachian Basin in the Northeast;
•  The SCOOP and STACK in Oklahoma;
•  The Arkoma Basin in Arkansas and Oklahoma;
•  The Anadarko Basin in Oklahoma;
•  The Marcellus Shale in West Virginia and Pennsylvania;
Southeastern New Mexico;
• 
•  The Barnett Shale in Texas;
•  The Granite Wash and Mississippi Shale in Oklahoma and Texas;
•  The Cana Woodford and Woodford Shales and the Cleveland Sand in Oklahoma;
•  The Eagle Ford Shale in Texas; and
•  The oil sands in Alberta, Canada.

Our operational division heads have an extensive track record in the infrastructure and oilfield service businesses with 

an average of over 27 years of infrastructure services experience and over 37 years of oilfield services experience. They bring 
valuable expertise and long-term customer relationships to our business. We provide our infrastructure services to private 
utilities, public investor owned utilities, or IOUs, and cooperatives, or Co-Ops, and our pressure pumping, natural sand 
proppant and other services to a diversified range of both public and private independent oil and natural gas producers. Our top 
five customers for the year ended December 31, 2019, representing 53% of our revenue, were Gulfport Energy Corporation, or 
Gulfport, the Puerto Rico Electric Power Authority, or PREPA, Montage Resources Corporation, or Montage Resources, HG 
Energy LLC, or HG Energy, and American Electric Power Company, Inc, or American Electric Power. For the year ended 
December 31, 2018, our top five customers, representing 77% of our revenue, were PREPA, Gulfport, Roan Resources LLC, or 
Roan Resources, Blue Ridge Mountain Resources, Inc., or Blue Ridge, and HG Energy. For the year ended December 31, 2017, 
our top five customers, representing 71% of our revenue, were Gulfport, PREPA, Newfield Exploration Company, or Newfield, 
Rice Energy, Inc., or Rice Energy, and Surge Operating LLC, or Surge Operating.

Our Services

Our revenues, operating (loss) income and identifiable assets are primarily attributable to four reportable segments: 

infrastructure services, pressure pumping services, natural sand proppant services and drilling services. For the year ended 
December 31, 2018, we identified three reportable segments consisting of infrastructure services, pressure pumping services 
and natural sand proppant services. Based on our assessment of FASB ASC 280, Segment Reporting, guidance at December 31, 
2019, we changed our reportable segment presentation in 2019 to include drilling services, which includes Bison Drilling and 
Field Services, LLC, Bison Trucking LLC, Panther Drilling Systems LLC, Mako Acquisitions LLC and White Wing Tubular 
LLC, as its own reportable segment. The results for the years ended December 31, 2018 and 2017 have been retroactively 
adjusted to reflect this change in reportable segments. For additional information, see Note 21 to our consolidated financial 
statements included elsewhere in this annual report.

Infrastructure Services 

Our infrastructure services business provides construction, upgrade, maintenance and repair services to the electrical 

infrastructure industry. We offer a broad range of services on electric transmission and distribution, or T&D, networks and 
substation facilities, which include construction, upgrade, maintenance and repair of high voltage transmission lines, 
substations and lower voltage overhead and underground distribution systems. Our commercial services include the installation, 
maintenance and repair of commercial wiring. We also provide storm repair and restoration services in response to storms and 
other disasters. We provide infrastructure services primarily in the northeast, southwest and midwest portions of the United 
States. 

We currently have agreements in place with private utilities, public IOUs and Co-Ops. Since we commenced 

operations in this line of business, substantially all of our infrastructure revenue has been generated from storm restoration 
work, primarily from PREPA, due to damage caused by Hurricane Maria. On October 19, 2017, Cobra Acquisitions LLC, or 
Cobra, and PREPA entered into an emergency master services agreement for repairs to PREPA’s electrical grid. The one-year 
contract, as amended, provided for payments of up to $945 million. On May 26, 2018, Cobra and PREPA entered into a second 
one-year, $900 million master services agreement to provide additional repair services and begin the initial phase of 
reconstruction of the electrical power system in Puerto Rico. Our work under each of the contracts with PREPA ended on 
March 31, 2019. 

As of December 31, 2019, PREPA owed us approximately $227 million for services we performed, excluding $42 

million of interest charged on these delinquent balances as of December 31, 2019. See Note 2. Summary of Significant 

2

 
 
 
 
 
Accounting Policies-Accounts Receivable to our consolidated financial statements included elsewhere in this annual report. 
PREPA is subject to bankruptcy proceedings, which were filed in July 2017 and are currently 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 contracts is largely 
dependent upon funding from the Federal Emergency Management Agency or other sources. On September 30, 2019, we filed 
a motion with the U.S. District Court for the District of Puerto Rico seeking recovery of the amounts owed to us by PREPA. 
This motion has been stayed by the court until a status conference scheduled to be held on June 17, 2020. For more information 
regarding this action as well as other legal actions and governmental investigations related to our work for PREPA, see Item 
1A. “Risk Factors—Risks Related to Our Business and the Industries We Serve” and Note 20. Commitments and Contingencies 
to our consolidated financial statements included elsewhere in this annual report. 

Upon the completion of our work in Puerto Rico on March 31, 2019, we focused on right-sizing our infrastructure 
operations and performing required maintenance on our equipment, which had been subjected to harsh working conditions. 
This process, with its associated costs, was completed during the fourth quarter of 2019.

Demand for our infrastructure services in the continental United States has increased since we began operations in 

2017. We had a total of approximately 140 transmission and distribution crews as of December 31, 2019, as compared to 
approximately 105 at December 31, 2018 and approximately 50 at December 31, 2017. Transmission crew size varies based 
upon the scope of the project and factors such as voltage, structure type, number of conductors and type of foundation. Each 
distribution crew generally consists of five employees. These transmission and distribution crews are working for multiple 
utilities primarily across the northeastern, midwestern and southwestern portions of the United States. We recently hired a new 
president for our infrastructure division and have added experienced industry personnel to key management positions. With this 
team in place, we believe we will be able to grow our customer base and increase our revenues in the continental United States 
over the coming years. We also believe that the skill sets and experience of our crews will afford us enhanced bidding 
opportunities in both the U.S. and overseas.

Pressure Pumping Services

Pressure Pumping. We provide pressure pumping services, also known as hydraulic fracturing, to exploration and 

production companies. These services are intended to optimize hydrocarbon flow paths during the completion phase of 
horizontal shale wellbores. Currently, we provide pressure pumping services in the Utica Shale of Eastern Ohio and the mid-
continent region in Oklahoma. We currently own six fleets of pressure pumping equipment. As of February 26, 2020, three of 
the fleets were staffed and providing services in the northeast. 

Our pressure pumping services include high-pressure hydraulic fracturing services. Fracturing services are performed 
to enhance the production of oil and natural gas from formations having low permeability such that the flow of hydrocarbons is 
restricted. We have significant expertise in multistage fracturing of horizontal oil and natural gas producing wells in shale and 
other unconventional geological formations.

The fracturing process consists of pumping a fracturing fluid into a well at sufficient pressure to fracture the 
formation. Materials known as proppants, in our case primarily sand or ceramic beads, are suspended in the fracturing fluid and 
are pumped into the fracture to prop it open. The fracturing fluid is designed to “break,” or loosen viscosity, and be forced out 
of the formation by its pressure, leaving the proppants suspended in the fractures created, thereby increasing the mobility of the 
hydrocarbons. As a result of the fracturing process, production rates are usually enhanced substantially, thus increasing the rate 
of return for the operator.

We own and operate fleets of mobile hydraulic fracturing units and other auxiliary heavy equipment to perform 

fracturing services. Our hydraulic fracturing units consist primarily of a high pressure hydraulic pump, an engine, a 
transmission and various hoses, valves, tanks and other supporting equipment that are typically mounted to a flat-bed trailer. As 
of December 31, 2019, our pressure pumping business included six high pressure fleets consisting of an aggregate 117 high 
pressure fracturing units with pump nameplate capacity of 291,750 horsepower. We are currently in the process of converting a 
portion of our pressure pumping fleet to include dynamic gas blending, or DGB, capabilities to meet recent shifts in customer 
demand, with the initial converted units expected to be field tested in the coming weeks. 

We refer to the group of fracturing units, other equipment and vehicles necessary to perform a typical fracturing job as 

a “fleet” and the personnel assigned to each fleet as a “crew.” We usually operate on a 24-hour-per-day basis and we typically 
staff three crews per fleet. All of our fracturing units and high pressure pumps are manufactured to our specifications to 
enhance the performance and durability of our equipment and meet our customers’ needs.

3

 
 
 
 
 
 
 
Each hydraulic fracturing fleet includes a mobile, on-site control center that monitors pressures, rates and volumes, as 

applicable. From there, our field-level managers supervise the job-site by radio. Each control center is equipped with high 
bandwidth satellite hardware that provides continuous upload and download of job telemetry data. The data is delivered on a 
real-time basis to on-site job personnel, the operator and personnel at our headquarters for display in both digital and graphical 
form. 

An important element of fracturing services is determining the proper fracturing fluid, proppants and injection 

program to maximize results. In virtually all of our hydraulic fracturing jobs, our customers specify the composition of the 
fracturing fluid to be used. The fracturing fluid may contain hazardous substances, such as hydrochloric acid and certain 
petrochemicals. Our customers are responsible for the disposal of the fracturing fluid that flows back out of the well as waste 
water. The customers remove the water from the well using a controlled flow-back process, and we are generally not involved 
in that process or in the disposal of the fluid.

Sand Hauling. Our sand hauling services provide last-mile trucking and logistics services for proppant used in 
completion activities in the Utica Shale, Permian Basin and SCOOP/STACK. As of December 31, 2019, we owned a fleet of 58 
trucks. Additionally, we had 28 owner operator drivers providing sand hauling services as of December 31, 2019.

Water Transfer. Our water transfer services provide water sourcing and water transfer services primarily for 
completion activities in the mid-continent region. As of December 31, 2019, we owned 136 water transfer pumps and 117 miles 
of layflat hose. 

Master Services Agreements. We contract with most of our pressure pumping customers under master service 

agreements, or MSAs. Generally, our MSAs, including those relating to our hydraulic fracturing services, specify payment 
terms, audit rights and insurance requirements and allocate certain operational risks through indemnity and similar provision.

In October 2014, we entered into a long-term contract with Gulfport to provide pressure pumping services. As 
amended and restated, this contract has a term ending on December 31, 2021. Gulfport is seeking to terminate this contract. For 
additional information regarding Gulfport's action, see Note 20. Commitments and Contingencies to our consolidated financial 
statements included elsewhere in this annual report.

Natural Sand Proppant Services

In our natural sand proppant business, we mine, process and sell sand. We also buy processed sand from suppliers on 
the spot market and resell that sand. Natural sand proppant, also known as frac sand, is the most widely used type of proppant 
due to its broad applicability in unconventional oil and natural gas wells and its cost advantage relative to other proppants. 
Natural frac sand may be used as proppant in all but the highest pressure and temperature environments and is being employed 
in nearly all major U.S. unconventional oil and natural gas producing basins, including those in which we operate.

At our Barron County and Jackson County, Wisconsin plants, we mine and process sand into premium 

monocrystalline sand (also known as frac sand), a specialized mineral that is used as a proppant. We can also purchase raw or 
washed sand and process it at our indoor sand processing plant located in Pierce County, Wisconsin, however, this facility has 
been temporarily idled since September 2018 due to market conditions. We sell sand to our customers for use in their hydraulic 
fracturing operations to enhance recovery rates from unconventional wells. Our sand processing plants produce a range of frac 
sand sizes for use in all major North American shale basins, including a majority of the standard proppant sizes as defined by 
the ISO/API 13503-2 specifications. These grain sizes can be customized to meet the demands of our customers with respect to 
a specific well. Our supply of Jordan substrate exhibits the physical properties necessary to withstand the completion and 
production environments of the wells in these shale basins. Our indoor processing plant in Pierce County, Wisconsin is 
designed for year-round continuous wet and dry plant operation. Our processing plants in Barron County and Jackson County, 
Wisconsin have indoor dry plants designed to operate year-round and outdoor wet plants that generally operate eight months 
per year.

We also provide logistics solutions to facilitate delivery of our frac sand products to our customers. Our frac sand 

products are primarily shipped by rail to our customers in the Utica Shale, SCOOP/STACK, DJ Basin, Permian Basin and the 
Montney Shale in British Columbia and Alberta, Canada. Our logistics capabilities in this regard are important to our 
customers, who focus on both the reliability and flexibility of product delivery. Because our customers generally find it 
impractical to store frac sand in large quantities near their job sites, they typically prefer product to be delivered where and as 
needed, which requires predictable and efficient loading and shipping capabilities. We contract with third party providers to 
transport our frac sand products to railroad facilities for delivery to our customers. We currently lease or have access to origin 
transloading facilities on the Canadian National Railway Company (CN), Union Pacific (UP), Burlington Northern Santa Fe 

4

 
 
 
 
 
 
 
 
 
(BNSF) and the Canadian Pacific (CP) rail systems and use an in-house railcar fleet that we lease from various third parties to 
deliver our frac sand products to our customers. Origin transloading facilities on multiple railways allow us to provide 
predictable and efficient loading and shipping of our frac sand products. We also utilize a destination transloading facility in 
Yorkville, Ohio, to serve the Utica Shale, and utilize destination transloading facilities located in other North American 
resource plays, including the Montney Shale, to meet our customers’ delivery needs.

Drilling Services

During the periods discussed in this report, we offered contract land and directional drilling services as well as rig 

moving services.  

Contract Drilling. As part of our contract drilling services, we provided both vertical and horizontal drilling services 
to customers in the Permian Basin of West Texas. However, due to current market conditions, we have temporarily shut down 
our contract land drilling operations beginning in December 2019. We will monitor market conditions to determine if and when 
we will re-commence our contract land drilling services. As of December 31, 2019, we owned 12 land drilling rigs, ranging 
from 800 to 1,600 horsepower, eight of which are specifically designed for drilling horizontal and directional wells. 

A land drilling rig generally consists of engines, a hoisting system, a rotating system, a drawworks, a mast, pumps and 
related equipment to circulate the drilling fluid under various pressures, blowout preventers, drill string and related equipment. 
The engines power the different pieces of equipment, including a rotary table or top drive that turns the drill pipe, or drill string, 
causing the drill bit to bore through the subsurface rock layers. Drilling rigs use long strings of drill pipe and drill collars to 
drill wells. Drilling rigs are also used to set heavy strings of large-diameter pipe, or casing, inside the borehole. Because the 
total weight of the drill string and the casing can exceed 500,000 pounds, drilling rigs require significant hoisting and braking 
capacities. Generally, a drilling rig’s hoisting system is made up of a mast, or derrick, a drilling line, a traveling block and hook 
assembly and ancillary equipment that attaches to the rotating system, a mechanism known as the drawworks. The drawworks 
mechanism consists of a revolving drum, around which the drilling line is wound, and a series of shafts, clutches and chain and 
gear drives for generating speed changes and reverse motion. The drawworks also houses the main brake, which has the 
capacity to stop and sustain the weights used in the drilling process. When heavy loads are being lowered, a hydromatic or 
electric auxiliary brake assists the main brake to absorb the great amount of energy developed by the mass of the traveling 
block, hook assembly, drill pipe, drill collars and drill bit or casing being lowered into the well.

The rotating equipment from top to bottom consists of a swivel, the kelly bushing, the kelly, the rotary table, drill pipe, 

drill collars and the drill bit. We refer to the equipment between the swivel and the drill bit as the drill stem. The swivel 
assembly sustains the weight of the drill stem, permits its rotation and affords a rotating pressure seal and passageway for 
circulating drilling fluid into the top of the drill string. The swivel also has a large handle that fits inside the hook assembly at 
the bottom of the traveling block. Drilling fluid enters the drill stem through a hose, called the rotary hose, attached to the side 
of the swivel. The kelly is a triangular, square or hexagonal piece of pipe, usually 40 feet long, that transmits torque from the 
rotary table to the drill stem and permits its vertical movement as it is lowered into the hole. The bottom end of the kelly fits 
inside a corresponding triangular, square or hexagonal opening in a device called the kelly bushing. The kelly bushing, in turn, 
fits into a part of the rotary table called the master bushing. As the master bushing rotates, the kelly bushing also rotates, 
turning the kelly, which rotates the drill pipe and thus the drill bit. Drilling fluid is pumped through the kelly on its way to the 
bottom. The rotary table, equipped with its master bushing and kelly bushing, supplies the necessary torque to turn the drill 
stem. The drill pipe and drill collars are both steel tubes through which drilling fluid can be pumped. Drill pipe comes in 30-
foot sections, or joints, with threaded sections on each end. Drill collars are heavier than drill pipe and are also threaded on the 
ends. Collars are used on the bottom of the drill stem to apply weight to the drill bit. At the end of the drill stem is the bit, 
which chews up the formation rock and dislodges it so that drilling fluid can circulate the fragmented material back up to the 
surface where the circulating system filters it out of the fluid.

Drilling fluid, often called drilling mud, is a mixture of clays, chemicals and water or oil, which is carefully 

formulated for the particular well being drilled. Bulk storage of drilling fluid materials, the pumps and the mud-mixing 
equipment are placed at the start of the circulating system. Working mud pits and reserve storage are at the other end of the 
system. Between these two points the circulating system includes auxiliary equipment for drilling fluid maintenance and 
equipment for well pressure control. Within the system, the drilling mud is typically routed from the mud pits to the mud pump 
and from the mud pump through a standpipe and the rotary hose to the drill stem. The drilling mud travels down the drill stem 
to the bit, up the annular space between the drill stem and the borehole and through the blowout preventer stack to the return 
flow line. It then travels to a shale shaker for removal of rock cuttings, and then back to the mud pits, which are usually steel 
tanks. The reserve pits, usually one or two fairly shallow excavations, are used for waste material and excess water around the 
location.

There are numerous factors that differentiate drilling rigs, including their power generation systems, horsepower, 

maximum drilling depth and horizontal drilling capabilities. The actual drilling depth capability of a rig may be less than or 
more than its rated depth capability due to numerous factors, including the size, weight and amount of the drill pipe on the rig. 
The intended well depth and the drill site conditions determine the amount of drill pipe and other equipment needed to drill a 
well.

Our drilling rigs have rated maximum depth capabilities ranging from 12,500 feet to 20,000 feet. Of these drilling rigs, 
seven are electric rigs and five are mechanical rigs. An electric rig differs from a mechanical rig in that the electric rig converts 
the power from its generators (which in the case of mechanical rigs, power the rig directly) into electricity to power the rig. 
Depth and complexity of the well and drill site conditions are the principal factors in determining the specifications of the rig 
selected for a particular job. Power requirements for drilling jobs may vary considerably, but most of our mechanical drilling 
rigs employ six engines to generate between 800 and 1,200 horsepower, depending on well depth and rig design. Most drilling 
rigs capable of drilling in deep formations drill to measured depths greater than 10,000 to 18,000 feet. Generally, land rigs 
operate with four crews of five people and two tool pushers, or rig managers, rotating on a weekly or bi-weekly schedule.

We believe that our drilling rigs and other related equipment are in good operating condition. Our employees perform 

periodic maintenance and minor repair work on our drilling rigs.

Prior to our temporary shut down of these services in December 2019, we obtained our contracts for drilling oil and 
natural gas wells either through competitive bidding or through direct negotiations with customers. We typically entered into 
drilling contracts that provided for compensation on a daywork basis. Occasionally, we entered into drilling contracts that 
provided for compensation on a footage basis, however, a majority of such footage drilling contracts also provided for daywork 
rates for work outside core drilling activities contemplated by such footage contracts and under certain other circumstances. We 
have not historically entered into turnkey contracts; however, we may decide to enter into such contracts in the future. It is also 
possible that we may acquire such contracts in connection with future acquisitions of drilling assets. Contract terms generally 
depend on the complexity and risk of operations, the on-site drilling conditions, the type of equipment used, the anticipated 
duration of the work to be performed and market conditions.

Daywork Contracts. Under daywork drilling contracts, we provided equipment and labor and perform services under 

the direction, supervision and control of our customers. We were paid a specified operating daywork rate from the time the 
drilling unit is rigged up at the drilling location and is ready to commence operations. Additionally, the daywork drilling 
contracts typically provide for fees and/or a daywork rates for mobilization, demobilization, moving, standby time and for any 
continuous period that normal operations are suspended or cannot be carried on because of force majeure conditions. The 
daywork drilling contracts also generally provide that the customer has the right to designate the points at which casing will be 
set and the manner of setting, cementing and testing. Such specifications include hole size, casing size, weight, grade and 
approximate setting depth. Furthermore, the daywork drilling contracts specify the equipment, materials and services to be 
separately furnished by us and our customer. Under these contracts, liability is typically allocated so that our customer is solely 
responsible for the following: (i) damage to our surface equipment as a result of certain corrosive elements; (ii) damage to 
customer’s equipment; (iii) damage to our in-hole equipment; (iv) damage or loss to the hole; (v) damage to the underground; 
and (vi) costs and damages associated with a wild well. We remain responsible for any damage to our surface equipment 
(except for damage resulting from the presence of certain corrosive elements) and for pollution or contamination from spills of 
materials that originate above the surface, are wholly in our control and are directly associated with our equipment. Daywork 
drilling contracts generally allow the customer to terminate the contract prior to drilling to a specified depth. This right, 
however, is generally subject to early termination compensation, the amount of which depends on when the termination occurs.

Directional Drilling. Our directional drilling services provide for the efficient drilling and production of oil and 

natural gas from unconventional resource plays. Our directional drilling equipment includes mud motors used to propel drill 
bits and kits for measurement-while-drilling, or MWD, and electromagnetic, or EM, technology. MWD kits are down-hole 
tools that provide real-time measurements of the location and orientation of the bottom-hole assembly, which is necessary to 
adjust the drilling process and guide the wellbore to a specific target. This technology, coupled with our complementary 
services, allows our customers to drill wellbores to specific objectives within narrow location parameters within target 
horizons. The evolution of unconventional resource reserve recovery has increased the need for the precise placement of a 
wellbore. Wellbores often travel across long-lateral intervals within narrow formations as thin as ten feet. Our personnel are 
involved in all aspects of a well from the initial planning of a customer’s drilling program to the management and execution of 
the horizontal or directional drilling operation. 

As of December 31, 2019, we owned ten MWD kits and three EM kits used in vertical, horizontal and directional 

drilling applications, 89 mud motors, 16 air motors and an inventory of related parts and equipment. Currently, we perform our 
directional drilling services in the Utica Shale, Anadarko Basin, Arkoma Basin, Powder River Basin and Permian Basin.

6

 
 
 
 
 
 
 
 
Rig Moving. We provide rig moving services in the Permian Basin. As of December 31, 2019, we owned 46 trucks 

specifically tailored to move rigs and seven cranes to assist us in moving rigs.

Other Services

We also offer a variety of other energy services including coil tubing services, pressure control services, equipment 

rental services, crude oil hauling services, full service transportation, remote accommodation services, oilfield equipment 
manufacturing and infrastructure engineering services. Additionally, during certain of the periods discussed in this report, we 
offered flowback services, cementing services and acidizing services. Due to market conditions, we temporarily shut down our 
flowback, cementing and acidizing operations beginning in July 2019. We continue to monitor market conditions to determine 
if and when we will recommence these services.   

Coil Tubing. Coiled tubing services involve injecting coiled tubing into wells to perform various well-servicing and 

workover operations. Coiled tubing is a flexible steel pipe with a diameter of typically less than three inches and manufactured 
in continuous lengths of thousands of feet. It is wound or coiled on a truck-mounted reel for onshore applications. Due to its 
small diameter in certain iterations, coiled tubing can be inserted into existing production tubing and used to perform a variety 
of services to enhance the flow of oil or natural gas without using a larger, more costly workover rig. The principal advantages 
of using coiled tubing in a workover include the ability to (i) continue production from the well without interruption, thus 
reducing the risk of formation damage, (ii) move continuous coiled tubing in and out of a well significantly faster than 
conventional pipe in the case of a workover rig, which must be jointed and unjointed, (iii) direct fluids into a wellbore with 
more precision, allowing for improved stimulation fluid placement, (iv) provide a source of energy to power a downhole mud 
motor or manipulate down-hole tools and (v) enhance access to remote fields due to the smaller size and mobility of a coiled 
tubing unit. As of December 31, 2019, we had one coiled tubing unit capable of running 25,000 feet of two and five eighths 
inch coil rated at 15,000 pounds per square inch, or psi,  two coiled tubing units capable of running 23,500 feet of two and three 
eighths inch coil rated at 15,000 psi, one coiled tubing unit capable of running 24,500 feet of two inch coil rated at 15,000 psi, 
two coiled tubing units capable of running over 22,000 feet of two inch coil rated at 10,000 psi and one coiled tubing unit 
capable of running 20,500 feet of two and three eighths inch coil rated at 15,000 psi in service.

Pressure Control. Our pressure control services consist of nitrogen and fluid pumping services. Our pressure control 

services equipment is designed to support activities in unconventional resource plays with the ability to operate under high 
pressures without having to delay or cease production during completion operations. Ceasing or suppressing production during 
the completion phase of an unconventional well could result in formation damage impacting the overall recovery of reserves. 
Our pressure control services help operators minimize the risk of such damage during completion activities. As of 
December 31, 2019, we had a total of four nitrogen pumping units and seven fluid pumping units. We provide pressure control 
services in the Eagle Ford Shale in South Texas and the Permian Basin in West Texas. 

•  Nitrogen Services. Nitrogen services involve the use of nitrogen, an inert gas, in various pressure pumping operations. 
When provided as a stand-alone service, nitrogen is used in displacing fluids in various oilfield applications. As of 
December 31, 2019, we had a total of four nitrogen pumping units capable of pumping at a rate of up to 3,000 
standard cubic feet per minute with pressures up to 10,000 psi. Pumping at these rates and pressures is typically 
required for the unconventional oil and natural gas resource plays we serve. 

•  Fluid Pumping Services. Fluid pumping services consist of maintaining well pressure, pumping down wireline tools, 
assisting coiled tubing units and the removal of fluids and solids from the wellbore for clean-out operations. As of 
December 31, 2019, we had seven fluid pumping units. Five of these units are coiled tubing double pump units 
capable of output of up to eight barrels per minute, and are rated for pressures up to 15,000 psi. Two of these units are 
quintuplex pump units capable of output of up to 15 barrels per minute, and are rated for pressures up to 15,000 psi. 

Equipment Rentals. Our equipment rental services provide a wide range of oilfield related equipment used in drilling, 

flowback and hydraulic fracturing services. Our equipment rentals consist of cranes, light plants, generators and other oilfield 
related equipment. We provide equipment rental in the Utica Shale, Eagle Ford Shale and mid-continent region. Additionally, 
we provide water transfer services in the northeast region. As of December 31, 2019, we owned 15 water transfer pumps, 35 
miles of layflat hose and ten miles of poly pipe for use in our water transfer operations.  

Crude Oil Hauling. We provide crude transportation services in the Permian Basin and mid-continent region. As of 

December 31, 2019, we had a fleet of 34 crude oil hauling trucks. 

7

 
 
 
 
 
 
 
Full Service Transportation. During 2019, we expanded our trucking operations to include brokering and hauling of 
general freight. We are currently operating this business out of South Florida and hauling freight throughout the United States. 
As of December 31, 2019, we had a fleet of 19 trucks dedicated to hauling general freight. 

Remote Accommodations. Our remote accommodations business provides housing, kitchen and dining, and 
recreational service facilities for oilfield workers located in remote areas away from readily available lodging. We provide a 
turnkey solution for our customers’ accommodation needs. These modular camps, when assembled together, form large 
dormitories, with kitchen/dining facilities and recreation areas. These camps are operated as “all inclusive,” where meals are 
prepared and provided for the guests. The primary revenue source for these camps is lodging fees. As of December 31, 2019, 
we had a capacity of 1,006 rooms, 612 of which are at Sand Tiger Lodge, our camp in northern Alberta, Canada, and 394 of 
which are available to be leased as rental equipment to a third party. As of December 31, 2019, 398 of our rooms were utilized. 

Oilfield Equipment Manufacturing. During the fourth quarter of 2019, we commenced oilfield equipment 
manufacturing operations at our facility located in Oklahoma. These operations will initially serve our internal needs for our 
water transfer and equipment rental businesses, but we intend to expand into third party sales in the future.

Infrastructure Engineering. During the fourth quarter of 2019, we began infrastructure engineering operations 

focused on the transmission and distribution industry. We currently have offices in California and Colorado.

As mentioned above, we also provided flowback and cementing and acidizing services. Due to market conditions, we 

temporarily shut-down our flowback, cementing and acidizing operations beginning in July 2019. We continue to monitor 
market conditions to determine if and when we will recommence these services. 

Flowback. Our flowback services consisted of production testing, solids control, hydrostatic testing and torque 

services. Due to market conditions, we temporarily shut-down our flowback operations beginning in July 2019. Flowback 
involves the process of allowing fluids to flow from the well following a treatment, either in preparation for an impending 
phase of treatment or to return the well to production. Our flowback equipment consists of manifolds, accumulators, valves, 
flare stacks and other associated equipment that combine to form up to a total of five well-testing spreads. We provided 
flowback services in the Appalachian Basin, the Eagle Ford Shale, the Haynesville Shale and mid-continent markets. As of 
December 31, 2019, we owned five production testing packages, 20 solids control packages, four hydrostatic testing packages 
and seven torque service packages. 

Cementing and Acidizing. We provide cementing and acidizing services in the Permian Basin. Due to market 

conditions, we temporarily shut-down our cementing and acidizing operations beginning in July 2019. Cementing services 
involve preparing and pumping cement into place in a wellbore to support and protect well casings and help achieve zonal 
isolation. Acidizing services involve pumping acid into a wellbore to improve productivity or injectivity. As of December 31, 
2019, we owned 13 twin cementers and associated equipment and seven acidizing pumps. 

Our Industries

Electric Infrastructure Industry

The electrical infrastructure industry involves the construction and maintenance of the electrical power grid, including, 
but not limited to, power generation, high voltage transmission lines, substations and low voltage distribution lines, all of which 
connect power generation facilities to end users. The industry also provides storm repair and restoration services in response to 
storms and other disasters. The industry is highly fragmented with more than 3,300 separate electric utility companies 
identified in the United States in 2019, spread across the following subgroups: IOUs, private utilities and Co-Ops.  

Demand for our services is driven by the construction of transmission lines, substations and distribution networks and 
is determined by the level of expenditures of utility companies. While expansion of the electrical grid is occurring, the majority 
of capital expenditures spent in recent years has surrounded the repair and maintenance of existing networks. Another factor 
that significantly influences the level of spending in the industry are natural disasters, which impact the electrical grid.  These 
natural disasters include, but are not limited to, thunderstorms, ice storms, snow storms, tornadoes, hurricanes, earthquakes, 
wildfires and lightning strikes. 

Certain barriers to entry exist in the markets in which we operate, including adequate financial resources, technical 

expertise, high safety ratings and a proven track record of operational success. We compete based upon our industry experience, 
technical expertise, financial and operational resources, geographic presence, industry reputation, our safety record and 
customer service. While we believe our customers consider a number of factors when selecting a service provider, they 

8

 
 
 
 
 
 
 
 
generally award most of their work through a bid process. Consequently, price is often a principal factor in determining which 
service provider is selected.

We believe that the age of the existing infrastructure across the United States and the spending trends in North 

America will benefit our operations and our ability to achieve our business objectives. 

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, 
including global and national health concerns, 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 prices of oil and natural gas. Over the past decade, 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. 
Throughout 2019, oil prices fluctuated between a low of $45.41 on January 1, 2019 and a high of $66.30 on April 23, 2019, and 
averaged $57.03 per barrel for the year. Certain factors related to world politics and major oil producers caused fluctuations in 
the oil price during 2019. However, overall, the price of oil was relatively stable throughout the year. 

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. We experienced a weakening 
in demand for our oilfield services beginning in the third quarter of 2019, which continued throughout the fourth quarter of 
2019 as a result of budget exhaustion and capital discipline from our customers. In addition, other factors, including access to 
capital and the need to refinance or repay maturing debt, have had a significant influence on some of our customers capital 
budgets and activity levels. While we still expect commodity prices to be the primary driver of capex spending and industry 
activity levels in the future, other factors may play a significant role in the ultimate level of capex spending by the companies 
that use our completion and production, natural sand proppant and contract land and directional drilling businesses. 

Although the ongoing volatility and depressed levels of activity are expected to persist until supply and demand for oil 

and natural gas come into balance, we believe that the following trends in our industry should benefit our operations and our 
ability to achieve our primary business objective when commodity prices recover: 

• 

Increased U.S. Petroleum field Production. According to the U.S. Energy Information Administration, or EIA, U.S. 
average petroleum field production was approximately 12.2 million barrels per day during 2019, an increase of 11.4% 
from 2018, with December 2019 average production of approximately 12.9 million barrels per day. U.S. average 
petroleum field production has grown at a compound annual growth rate of 9.2% over the period from 2009 through 
2019 due to production gains primarily from unconventional reservoirs. We expect continued growth from 
unconventional reservoirs in the future will result in increased demand for our services due to higher decline rates 
from these reservoirs, resulting in increased activity levels. 

9

 
 
 
 
• 

Increased use of horizontal drilling to develop unconventional resource plays. According to Baker Hughes, the 
horizontal rig count on December 27, 2019 was 703, or approximately 87% of the total U.S. onshore rig count. The 
horizontal rig count as a percentage of the overall onshore rig count has increased every year since 2007 when 
horizontal rigs represented only approximately 25% of the total U.S. onshore rig count at year-end. As a result of 
improvements in drilling and production enhancement technologies, oil and natural gas companies are increasingly 
developing unconventional resources such as tight sands and shales. Successful and economic production of these 
unconventional resource plays frequently requires horizontal drilling, fracturing and stimulation services. Drilling 
related activity for unconventional resources is typically done on tighter acre spacing and thus requires that more wells 
be drilled relative to conventional resources. We believe that all of these characteristics will drive the demand for our 
services in an improved commodity price environment.

• 

Tight oil production growth is expected to continue to be the primary driver of U.S. oil production growth. According 
to the EIA, U.S. tight oil production grew from approximately 430,000 barrels per day in 2007 to over 8.2 million 
barrels per day in 2019, representing approximately 63% of total U.S. crude oil production in 2019. A majority of this 
increase came from the Eagle Ford play in South Texas, the SCOOP/STACK plays in the mid-continent of Oklahoma, 
the Bakken Shale in the Williston Basin of North Dakota and Montana, and the Permian Basin in West Texas. We 

10

believe the Utica Shale and the Permian Basin, our primary business locations, will be key drivers of U.S. tight oil and 
natural gas production as those plays are developed further in the coming years.

•  Horizontal wells are heavily dependent on oilfield services. According to Baker Hughes, as of December 27, 2019, 
horizontal rigs accounted for approximately 87% of all rigs drilling in the United States, up from 25% at year-end 
2007. The scope of services for a horizontal well are greater than for a conventional well. Industry analysts report that 
the average horsepower, length of the lateral and number of fracture stages has continued to increase since 2008. We 
believe our commitment to provide services in unconventional plays, such as the Utica Shale and the Permian Basin, 
provide us the opportunity to compete in those regional markets where the majority of total footage is drilled each year 
in the United States.

•  New and emerging unconventional resource plays. In addition to the development of existing unconventional resource 

plays such as the Permian, Utica, Bakken, Eagle Ford, SCOOP/STACK, Barnett, Fayetteville, Cotton Valley, 
Haynesville, Marcellus and Woodford Shales, exploration and production companies continue to find new 
unconventional resources. These include oil and liquids-based shales in the Cana Woodford, Granite Wash and Powder 
River Basin resource plays. In certain cases, exploration and production companies have acquired vast acreage 
positions in these plays that require them to drill and produce hydrocarbons to hold the leased acreage. We believe 
these unconventional resource plays will increasingly drive demand for our services as they typically require the use 
of extended reach horizontal drilling, multiple stage fracture stimulation and high pressure completion capabilities.

•  Need for additional drilling activity to maintain production levels. With the increased maturity of the onshore 

conventional and, in many cases, unconventional resource plays, oil and natural gas production may be characterized 
as having steeper initial decline curves. Given average decline rates and the substantial reduction in activity over the 
past year, we believe that the number of wells drilled is likely to increase in coming years to maintain and grow 
current production levels. Once a well has been drilled, it requires recurring production and completion services, 
which we believe will also drive demand for our services.

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. These advancements have made the extraction of oil and natural gas increasingly cost-effective in formations 
that historically would have been unprofitable to develop, resulting in a greater number of wells being drilled. We believe that 
demand for proppant will grow over the long-term, primarily driven by the increase in the average amount of proppant 
consumed per horizontal rig and as a result of the following demand drivers:

• 

improvements in drilling rig productivity (from, among other things, pad drilling), resulting in more wells drilled per 
rig per year;

11

• 
• 
• 
• 
• 

increases in the number of wells drilled per acre;
increases in the length of the typical horizontal wellbore;
increases in the number of fracture stages per lateral foot in the typical completed horizontal wellbore;
increases in the volume of proppant used per fracturing stage; and
recurring efforts to offset steep production declines in unconventional oil and natural gas reservoirs, including the 
drilling of new wells and secondary hydraulic fracturing of existing wells.

In 2018 and 2019, several new and existing suppliers completed planned capacity additions of frac sand supply, 

particularly in the Permian Basin. The industry expansion, coupled with increased capital discipline and budget exhaustion, 
caused the frac sand market to become oversupplied, particularly in finer grades, during the second half of 2019. With the frac 
sand market oversupplied, pricing for certain grades has fallen significantly from the peaks experienced throughout 2018 and 
the first half of 2019. This oversupply has resulted in several industry participants idling and closing high cost mines in the 
recent months. As these closures continue and the number of industry participants decline, we expect the imbalance between 
supply and demand to narrow. Nevertheless, demand for our sand declined significantly in the second half of 2019 as a result of 
increased capital discipline by our customers and budget exhaustion, among other factors. We cannot predict if and when 
demand and pricing will recover sufficiently to return our natural sand proppant services segment to profitability. 

Our proppant sand reserves consist of Northern White silica sand, giving us access to a range of high-quality sand 

grades meeting or exceeding all API specifications, including a mix between concentrations of coarse grades (20/40 and 30/50 
mesh size) and finer grades (40/70 and 100 mesh size).  Our sample boring data and our historical production data have 
indicated that our reserves contain deposits of approximately 60% 40 mesh size or finer substrate.  The coarseness and 
conductivity of Northern White frac sand significantly enhances recovery of oil and liquids-rich gas by allowing hydrocarbons 
to flow more freely than is sometimes possible with native sand.  The low acid-solubility increases the integrity of Northern 
White frac sand relative to other proppants with higher acid-solubility, especially in shales where hydrogen sulfide and other 
acidic chemicals are co-mingled with the targeted hydrocarbons.  In addition, its crush resistant properties enable Northern 
White frac sand to be used in deeper drilling applications than the frac sand produced from many native mineral deposits.

We believe that the coarseness, conductivity, sphericity, acid-solubility, and crush-resistant properties of our Northern 

White sand reserves and our facilities’ connectivity to rail and other transportation infrastructure afford us a cost 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.

Our Strengths

Our primary business objective is to grow our operations and create value for our stockholders through organic growth 

opportunities and accretive acquisitions. We believe that the following strengths position us well to capitalize on activity in 
unconventional resource plays and achieve our primary business objective:

• 

• 

Long-term contractual and other regional relationships with a stable customer base. We are party to two long-term 
contracts with Gulfport to provide pressure pumping services and natural sand proppant services through December 
2021, although Gulfport is seeking to terminate the pressure pumping contract. See Note 20. Commitments and 
Contingencies to our consolidated financial statements included elsewhere in this annual report. In addition, our 
operational division heads and field managers have formed long-term relationships with our customer base. We 
believe these contractual and other relationships help provide us a more stable and growth-oriented client base in the 
unconventional shale markets as well as the infrastructure markets that we currently serve. 

Strategic geographic positioning, including primary presence in the Utica Shale, the SCOOP/STACK and the Permian 
Basin. We currently operate facilities and service centers to support our operations in major unconventional resource 
plays in the United States, including the Utica Shale in Eastern Ohio, the Permian Basin in West Texas, the SCOOP/
STACK in Oklahoma, the Marcellus Shale in West Virginia, the Granite Wash in Oklahoma and Texas, the Cana 
Woodford Shale in Oklahoma, the Eagle Ford Shale in South Texas and the oil sands in Alberta, Canada. We believe 
our geographic positioning within active oil and natural gas liquids resource plays will benefit us strategically as 
activity increases in these unconventional resource plays.

•  Experienced management and operating team. Our operational division heads have an extensive track record in the 

oilfield and infrastructure service businesses with an average of over 27 years of infrastructure services experience and 
over 37 years of oilfield services experience. In addition, our field managers have expertise in the areas in which they 
operate and understand the challenges that our customers face. We believe their knowledge of our industries and 

12

 
business lines enhances our ability to provide innovative, client-focused and basin-specific customer service, which 
we also believe strengthens our relationships with our customers.

• 

Young fleet of hydraulic fracturing equipment designed for horizontal wells. Our service fleet is predominantly 
comprised of equipment designed to optimize recovery from unconventional wells. Three of our pressure pumping 
fleets with total combined horsepower of 132,500 were built in 2017. We believe that our fleet of quality equipment 
will allow us to provide a high level of service to our customers and capitalize on future growth in the unconventional 
resource plays that we serve. In addition, we are currently in the process of converting a portion of our pressure 
pumping fleet to include DGB capabilities to meet recent shifts in customer demand, with the initial converted units 
expected to be field tested in the coming weeks. 

Our Business Strategy

We intend to achieve our primary business objective in connection with our infrastructure services by the successful 

execution of our business plan to strategically deploy equipment and personnel to provide infrastructure services across the 
United States. In the case of our oilfield services, we intend to achieve our primary business objective by the successful 
execution of our business plan to strategically deploy our equipment and personnel to provide pressure pumping services, 
natural sand proppant services and other energy services in unconventional resource plays, including the Utica Shale in Ohio, 
the SCOOP/STACK in Oklahoma and the Permian Basin in West Texas. We believe our infrastructure services optimize our 
customers’ ability to maintain, improve and expand their infrastructure and that our oil and natural gas services optimize our 
customers’ ultimate resources recovery and present value of hydrocarbon reserves. We seek to create cost efficiencies for our 
customers by providing a suite of complementary services designed to address a wide range of our customers’ needs. 
Specifically, we strive to create value for our stockholders through the following strategies:

• 

Leverage our broad range of services for cross-selling opportunities. We offer a complementary suite of services and 
products. Our infrastructure services division provides construction, upgrade, maintenance and repair services to the 
electrical infrastructure industry. Our pressure pumping services division provide hydraulic fracturing services for 
unconventional wells as well as sand hauling services and water transfer services. Our natural sand proppant services 
division mines, processes and sells natural sand proppant for hydraulic fracturing. Our drilling services division 
provides rental equipment, such as mud motors and operational tools, for both vertical and horizontal drilling as well 
as rig moving services. Additionally, we provide coil tubing services, pressure control services, equipment rentals, 
crude oil hauling, full service transportation, remote accommodations, oilfield equipment manufacturing and 
infrastructure engineering services. We intend to leverage our existing customer relationships and operational track 
record to cross sell our services and increase our exposure and product offerings to our existing customers, broaden 
our customer base and expand opportunistically to other geographic regions in which our customers have operations, 
as well as to create operational efficiencies for our customers.

•  Expand through selected, accretive acquisitions. To complement our organic growth, we intend to actively pursue 

selected, accretive acquisitions of businesses and assets, primarily related to our infrastructure services, completion 
and production services and industrial based companies, that can meet our targeted returns on invested capital and 
enhance our portfolio of products and services, market positioning and/or geographic presence. We believe this 
strategy will facilitate the continued expansion of our customer base, geographic presence and service offerings. We 
also believe that our industry contacts and those of Wexford Capital LP, or Wexford, our largest stockholder, may be 
helpful to facilitate the identification of acquisition opportunities. We may use our common stock as consideration for 
accretive acquisitions.

•  Maintain a conservative balance sheet. We seek to maintain a conservative balance sheet, which allows us to better 
react to changes in commodity prices and related demand for our services, as well as overall market conditions. 

•  Expand our services to meet expanding customer demand. The scope of services for horizontal wells is greater than 

that for conventional wells. Industry analysts have reported that the average horsepower required for current 
completion designs, amount of sand per lateral foot, length of lateral and number of fracture stages has continued to 
increase since 2008. We consistently monitor market conditions and intend to expand the capacity and scope of our 
business lines if, and when, demand warrants in resource plays in which we currently operate, as well as in new 
resource plays. If we perceive unmet demand in our principal geographic locations for different service lines, we will 
seek to expand our current service offerings to meet that demand.

•  Expand our energy infrastructure business unit.  Industry analysts have reported that spending in the T&D industry 

will exceed $60 billion each year through 2022. We consistently monitor market conditions and intend to expand the 

13

 
capacity and scope of our energy infrastructure services as demand warrants in geographic areas in which we currently 
operate, as well as in new geographic areas. 

• 

Leverage our experienced operational management team expertise. We seek to manage the services we provide as 
closely as possible to the needs of our customer base. Our operational division heads have long-term relationships 
with our largest customers. We intend to leverage these relationships and our operational management team’s expertise 
to deliver innovative, client focused and services to our customers.

•  Capitalize on activity in the unconventional resource plays. Our oil and natural gas service equipment is designed to 
provide a broad range of services for unconventional wells, and our operations are strategically located in major 
unconventional resource plays. During 2019, oil prices fluctuated between a low of $45.41 on January 1, 2019 and a 
high of $66.30 on April 23, 2019, and averaged $57.03 per barrel for the year. Certain factors related to world politics 
and major oil producers caused fluctuations in the oil price during 2019. However, overall, the price of oil was 
relatively stable throughout the year. If commodity prices stabilize at current levels or improve, we expect to 
experience increases in demand for our services and products. We will seek to capitalize on any increase in activity in 
these markets and diversify our operations across additional unconventional resource basins. Our core operations are 
currently focused in the Utica Shale in Ohio, the SCOOP/STACK in Oklahoma and the Permian Basin in West Texas. 
We intend to continue to strategically deploy assets to these and other unconventional resource basins and will look to 
capitalize on further growth in emerging unconventional resource plays as they develop.

Marketing and Customers

Our customers consist primarily of private utilities, IOUs, Co-Ops, independent oil and natural gas producers and 

land-based drilling contractors in North America. For the years ended December 31, 2019 and 2018, we had approximately 590 
and 460 customers, respectively, including Gulfport, PREPA, Montage Resources, HG Energy and American Electric Power. 
Our top five customers accounted for approximately 53%, 77% and 71%, respectively, of our revenue for the years ended 
December 31, 2019, 2018 and 2017. During the year ended December 31, 2019, Gulfport and PREPA accounted for 20% and 
15%, respectively, of our revenue. For the year ended December 31, 2018, PREPA and Gulfport accounted for 60% and 8%, 
respectively, of our revenue. For the year ended December 31, 2017, Gulfport and PREPA accounted for 30% and 29%, 
respectively, of our revenue. Although we believe we have a broad customer base and wide geographic coverage of operations, 
it is likely that we will continue to derive a significant portion of our revenue from a relatively small number of customers in 
the future. If a major customer decides not to continue to use our services and is not replaced by new or existing customers, our 
revenue would decline and our operating results and financial condition would be harmed. Our services for PREPA ended in the 
first quarter of 2019 and we are currently involved in a lawsuit with Gulfport in which Gulfport is seeking to terminate our 
pressure pumping contract with it and receive certain alleged damages. See Note 20. Commitments and Contingencies to our 
consolidated financial statements included elsewhere in this annual report.  

Infrastructure Services Backlog

Estimated backlog for our infrastructure services represents the amount of revenue we expect to realize over the next 
36 months from future work on uncompleted construction projects, including new contracts under which work has not begun.  
Our estimated backlog also includes amounts payable to us under master service and other service agreements. Estimated 
infrastructure services backlog for work under master service and other service agreements is determined based on historical 
trends, experience from similar projects and estimates of customer demand based on communications with our customers. As of 
December 31, 2019, our infrastructure services backlog was $490 million, all of which is attributable to operations in the 
continental United States. In 2020, we expect to realize approximately $148 million of our backlog. 

Approximately $479 million of our infrastructure services backlog as of December 31, 2019 is attributable to amounts 
under master service or other service agreements pursuant to which our customers are not contractually committed to purchase 
a minimum amount of services. Most of these agreements can be canceled on short or no advance notice. Timing of revenue for 
our infrastructure services backlog can be subject to change as a result of our delays, customer delays, regulatory delays or 
other factors. These changes could cause estimated revenue to be realized in periods later than originally expected, or not at all.  
We occasionally experience postponements, cancellations and reductions in expected future work from master service 
agreements or other service agreements due to changes in our customers’ spending plans, market volatility, governmental 
funding and regulatory factors. There can be no assurance as to our customers’ requirements or the accuracy of our estimates.  
As a result, our backlog as of any particular date is an uncertain indicator of future revenue and earnings.

14

 
 
 
Backlog is not a term recognized under accounting principles generally accepted in the United States; however, it is a 

common measurement used in the infrastructure industry.  As such, our methodology for determining backlog may not be 
comparable to the methodologies used by others.  

Operating Risks and Insurance

Our operations are subject to hazards inherent in the energy services industry, such as accidents, blowouts, explosions, 

fires and spills and releases that can cause:

• 
• 
• 

personal injury or loss of life;
damage or destruction of property, equipment, natural resources and the environment; and
suspension of operations.

In addition, claims for loss of oil and natural gas production and damage to formations can occur in the oilfield 

services industry. If a serious accident were to occur at a location where our equipment and services are being used, it could 
result in us being named as a defendant in lawsuits asserting large claims. 

Because our business involves the transportation of heavy equipment and materials, we may also experience traffic 

accidents which may result in spills, property damage and personal injury.

Despite our efforts to maintain safety standards, from time to time we have suffered accidents in the past and 
anticipate that we could experience accidents in the future. In addition to the property damage, personal injury and other losses 
from these accidents, the frequency and severity of these incidents affect our operating costs and insurability and our 
relationships with customers, employees, regulatory agencies and other parties. Any significant increase in the frequency or 
severity of these incidents, or the general level of compensation awards, could adversely affect the cost of, or our ability to 
obtain, workers’ compensation and other forms of insurance, and could have other material adverse effects on our financial 
condition and results of operations. 

We maintain commercial general liability, workers’ compensation, business auto, commercial property, motor truck 

cargo, umbrella liability, in certain instances, excess liability, and directors and officers insurance policies providing coverages 
of risks and amounts that we believe to be customary in our industry. With respect to our hydraulic fracturing operations, 
coverage would be available under our policy for any surface or subsurface environmental clean-up and liability to third parties 
arising from any surface or subsurface contamination. We also have certain specific coverages for some of our businesses, 
including our remote accommodation services, pressure pumping services, contract and directional drilling services and 
infrastructure engineering services. 

Although we maintain insurance coverage of types and amounts that we believe to be customary in the industry, we 

are not fully insured against all risks, either because insurance is not available or because of the high premium costs relative to 
perceived risk. Further, insurance rates have in the past been subject to wide fluctuation and changes in coverage could result in 
less coverage, increases in cost or higher deductibles and retentions. Liabilities for which we are not insured, or which exceed 
the policy limits of our applicable insurance, could have a material adverse effect on us. See Item 1A. “Risk Factors” for a 
description of certain risks associated with our insurance policies.

Safety and Remediation Program

In the energy services industry, an important competitive factor in establishing and maintaining long-term customer 

relationships is having an experienced and skilled workforce. Many of our large customers place an emphasis not only on 
pricing, but also on safety records and quality management systems of contractors. We have committed resources toward 
employee safety and quality management training programs. Our field employees are required to complete both technical and 
safety training programs. Further, as part of our safety program and remediation procedures, we check treating iron for any 
defects on a periodic basis to avoid iron failure during hydraulic fracturing operations, marking such treating iron to reflect the 
most recent testing date. We also regularly monitor pressure levels in the treating iron used for fracturing and the surface casing 
to verify that the pressure and flow rates are consistent with the job specific model in an effort to avoid failure. As part of our 
safety procedures, we also have the capability to shut down our pressure pumping and fracturing operations both at the pumps 
and in our data van. In addition, we maintain spill kits on location for containment of pollutants that may be spilled in the 
process of providing our hydraulic fracturing services. The spill kits are generally comprised of pads and booms for absorption 
and containment of spills, as well as soda ash for neutralizing acid. Fire extinguishers are also in place on job sites at each 
pump.

15

 
 
 
 
 
 
 
 
Historically, we have used third-party contractors to provide remediation and spill response services when necessary to 

address spills that were beyond our containment capabilities. None of these prior spills were significant, and we have not 
experienced any incidents, citations or legal proceeding relating to our hydraulic fracturing or crude hauling services for 
environmental concerns. To the extent our hydraulic fracturing or other energy services operations result in a future spill, leak 
or other environmental impact that is beyond our ability to contain, we intend to engage the services of such remediation 
company or an alternative company to assist us with clean-up and remediation.

Competition

The markets in which we operate are highly competitive. To be successful, a company must provide services and 

products that meet the specific needs of oil and natural gas exploration and production companies, drilling services contractors, 
private utilities, IOUs and Co-Ops at competitive prices.

We provide our services and products across the United States and in Alberta, Canada and we compete against 

different companies in each service and product line we offer. Our competition includes many large and small energy service 
companies, including the largest integrated oilfield services companies and energy infrastructure companies. Our major 
competitors for our infrastructure services business include MYR Group, Inc, Quanta Services, Inc, MasTec, Inc. and EMCOR 
Group, Inc. Our major competitors in pressure pumping services include Halliburton Company, U.S. Well Services, LLC, 
Schlumberger Limited, NexTier Oilfield Solutions, Inc., RPC Incorporated, Liberty Oilfield Services, Inc. and FTS 
International, Inc. Our major competitors in our natural sand proppant services business are Badger Mining Corporation, Covia 
Holdings Corporation, Hi-Crush Partners LP, Preferred Proppants LLC, Smart Sand, Inc., Emerge Energy Services LP and U.S. 
Silica Holdings Inc. 

We believe that the principal competitive factors in the market areas that we serve are quality of service and products, 
reputation for safety, technical proficiency, availability and price. While we must be competitive in our pricing, we believe our 
customers select our services and products based on the local leadership and expertise that our field management and operating 
personnel use to deliver quality services and products.

Regulation

We operate under the jurisdiction of a number of regulatory bodies that regulate worker safety standards, permitting 
and inspection requirements applicable to construction projects, building and electrical codes regulations, government project 
regulations, the handling of hazardous materials, the transportation of explosives, the protection of human health and the 
environment and driving standards of operation. Regulations concerning equipment certification create an ongoing need for 
regular maintenance which is incorporated into our daily operating procedures. The oil and natural gas and infrastructure 
industries are subject to environmental and other regulation pursuant to local, state and federal legislation.

Regulation of Infrastructure Services

In our infrastructure business, our operations are subject to various federal, state and local laws and regulations 

including:

licensing, permitting and inspection requirements applicable to contractors, electricians and engineers;
regulations relating to worker safety;
permitting and inspection requirements applicable to construction projects;

• 
• 
• 
•  wage and hour regulations;
• 
• 

building and electrical codes; and
special bidding, procurement and other requirements on government projects.

We believe that we have all the licenses required to conduct our energy infrastructure services and that we are in

substantial compliance with applicable regulatory requirements.  Our failure to comply with applicable regulations could result 
in substantial fines or revocation of our operating licenses, as well as give rise to termination or cancellation rights under our 
contracts or disqualify us from future bidding opportunities.

16

 
 
 
 
 
 
Transportation Matters

In connection with the transportation and relocation of our equipment and shipment of frac sand, crude oil and general 
cargo, we operate trucks and other heavy equipment. As such, we operate as a motor carrier in providing certain of our services 
and therefore are subject to regulation by the United States Department of Transportation and by various state agencies. These 
regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier 
operations, driver licensing and insurance requirements, financial reporting and review of certain mergers, consolidations and 
acquisitions, and transportation of hazardous materials (HAZMAT). Our trucking operations are subject to possible regulatory 
and legislative changes that may increase our costs. Some of these possible changes include increasingly stringent 
environmental regulations, changes in the hours of service regulations which govern the amount of time a driver may drive or 
work in any specific period, onboard black box recorder device requirements or limits on vehicle weight and size. 

Interstate motor carrier operations are subject to safety requirements prescribed by the Federal Motor Carrier Safety 
Administration, or FMCSA, a unit within the United States Department of Transportation. To a large degree, intrastate motor 
carrier operations are subject to state safety regulations that mirror federal regulations. Matters such as the weight and 
dimensions of equipment are also subject to federal and state regulations. From time to time, various legislative proposals are 
introduced, including proposals to increase federal, state or local taxes, including taxes on motor fuels, which may increase our 
costs or adversely impact the recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes 
applicable to us will be enacted.

Certain motor vehicle operators require registration with the Department of Transportation. This registration requires 
an acceptable operating record. The Department of Transportation periodically conducts compliance reviews and may revoke 
registration privileges based on certain safety performance criteria which could result in a suspension of operations. The rating 
scale consists of “satisfactory,” “conditional” and “unsatisfactory” ratings. As of December 31, 2019, all of our trucking 
operations have “satisfactory” ratings with the Department of Transportation. We have undertaken comprehensive efforts that 
we believe are adequate to comply with the regulations. Further information regarding our safety performance is available at 
the FMCSA website at www.fmcsa.dot.gov.

In December 2010, the FMCSA launched a program called Compliance, Safety, Accountability, or CSA, in an effort to 
improve commercial truck and bus safety. A component of CSA is the Safety Measurement System, or SMS, which analyzes all 
safety violations recorded by federal and state law enforcement personnel to determine a carrier’s safety performance. The 
SMS is intended to allow FMCSA to identify carriers with safety issues and intervene to address those problems. However, the 
agency has announced a future intention to revise its safety rating system by making greater use of SMS data in lieu of on-site 
compliance audits of carriers. At this time, we cannot predict the effect such a revision may have on our safety rating.

Environmental Matters and Regulation

Our operations are subject to stringent laws and regulations governing the discharge of materials into the environment 

or otherwise relating to environmental protection. Numerous federal, state and local governmental agencies, such as the U.S. 
Environmental Protection Agency, or the EPA, issue regulations that often require difficult and costly compliance measures that 
carry substantial administrative, civil and criminal penalties and may result in injunctive obligations for non-compliance. These 
laws and regulations may require the acquisition of a permit before commencing operations, restrict the types, quantities and 
concentrations of various substances that can be released into the environment in connection with our operations, limit or 
prohibit construction or drilling activities on certain lands lying within wilderness, wetlands, ecologically or seismically 
sensitive areas and other protected areas, require action to prevent or remediate pollution from current or former operations, 
such as plugging abandoned wells or closing pits, result in the suspension or revocation of necessary permits, licenses and 
authorizations, require that additional pollution controls be installed and impose substantial liabilities for pollution resulting 
from our operations or related to our owned or operated facilities. Liability under such laws and regulations is strict (i.e., no 
showing of “fault” is required) and can be joint and several. Moreover, it is not uncommon for neighboring landowners and 
other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous 
substances, hydrocarbons or other waste products into the environment. Changes in environmental laws and regulations occur 
frequently, and any changes that result in more stringent and costly pollution control or waste handling, storage, transport, 
disposal or cleanup requirements could materially adversely affect our operations and financial position, as well as the oil and 
natural gas industry and infrastructure industry in general. We have not experienced any material adverse effect from 
compliance with these environmental requirements. This trend, however, may not continue in the future.

Waste Handling. We handle, transport, store and dispose of wastes that are subject to the federal Resource 

Conservation and Recovery Act, as amended, or RCRA, and comparable state statutes and regulations promulgated thereunder, 
which affect our activities by imposing requirements regarding the generation, transportation, treatment, storage, disposal and 
17

 
 
 
 
 
 
cleanup of hazardous and non-hazardous wastes. With federal approval, the individual states administer some or all of the 
provisions of RCRA, sometimes in conjunction with their own, more stringent requirements. Although certain petroleum 
production wastes are exempt from regulation as hazardous wastes under RCRA, such wastes may constitute “solid wastes” 
that are subject to the less stringent requirements of non-hazardous waste provisions.

Administrative, civil and criminal penalties can be imposed for failure to comply with waste handling requirements. 

Moreover, the EPA or state or local governments may adopt more stringent requirements for the handling of non-hazardous 
wastes or categorize some non-hazardous wastes as hazardous for future regulation. Indeed, legislation has been proposed from 
time to time in Congress to re-categorize certain oil and natural gas exploration, development and production wastes as 
“hazardous wastes.” Several environmental organizations have also petitioned the EPA to modify existing regulations to 
recategorize certain oil and natural gas exploration, development and production wastes as “hazardous.” Also, in December 
2015, the EPA agreed in a consent decree to review its regulation of oil and gas waste. However, in April 2019, the EPA 
concluded that revisions to the federal regulations for the management of oil and gas waste are not necessary at this time. Any 
such changes in the laws and regulations could have a material adverse effect on our capital expenditures and operating 
expenses. Although we do not believe the current costs of managing our wastes, as presently classified, to be significant, any 
legislative or regulatory reclassification of oil and natural gas exploration and production wastes could increase our costs to 
manage and dispose of such wastes.

Remediation of Hazardous Substances. The Comprehensive Environmental Response, Compensation and Liability 

Act, as amended, which we refer to as CERCLA, or the “Superfund” law, and analogous state laws, generally imposes liability, 
without regard to fault or legality of the original conduct, on classes of persons who are considered to be responsible for the 
release of a “hazardous substance” into the environment. These persons include the current owner or operator of a 
contaminated facility, a former owner or operator of the facility at the time of contamination and those persons that disposed or 
arranged for the disposal of the hazardous substance at the facility. Under CERCLA and comparable state statutes, persons 
deemed “responsible parties” are subject to strict liability, that, in some circumstances, may be joint and several for the costs of 
removing or remediating previously disposed substances (including substances disposed of or released by prior owners or 
operators) or property contamination (including groundwater contamination), for damages to natural resources and for the costs 
of certain health studies. In addition, it is not uncommon for neighboring landowners and other third parties to file claims for 
personal injury and property damage allegedly caused by the hazardous substances released into the environment. In the course 
of our operations, we use materials that, if released, would be subject to CERCLA and comparable state statutes. Therefore, 
governmental agencies or third parties may seek to hold us responsible under CERCLA and comparable state statutes for all or 
part of the costs to clean up sites at which such “hazardous substances” have been released.

NORM. In the course of our operations, some of our equipment may be exposed to naturally occurring radioactive 

materials associated with oil and gas deposits and, accordingly may result in the generation of wastes and other materials 
containing naturally occurring radioactive materials, or NORM. NORM exhibiting levels of naturally occurring radiation in 
excess of established state standards are subject to special handling and disposal requirements, and any storage vessels, piping 
and work area affected by NORM may be subject to remediation or restoration requirements. Because certain of the properties 
presently or previously owned, operated or occupied by us may have been used for oil and gas production operations, it is 
possible that we may incur costs or liabilities associated with NORM.

Water Discharges. The Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean Water 
Act,” the Safe Drinking Water Act, the Oil Pollution Act and analogous state laws and regulations promulgated thereunder 
impose restrictions and strict controls regarding the unauthorized discharge of pollutants, including produced waters and other 
gas and oil wastes, into navigable waters of the United States, as well as state waters. The discharge of pollutants into regulated 
waters is prohibited, except in accordance with the terms of a permit issued by the EPA or the state. The Clean Water Act and 
regulations implemented thereunder also prohibit the discharge of dredge and fill material into regulated waters, including 
jurisdictional wetlands, unless authorized by a permit issued by the U.S. Army Corps of Engineers, which we refer to as the 
Corps. On June 29, 2015, the EPA and the Corps jointly promulgated final rules redefining the scope of waters protected under 
the Clean Water Act. However, on October 22, 2019, the agencies published a final rule to repeal the 2015 rules.  The 2015 rule 
and the 2019 repeal are subject to several ongoing legal challenges.  Also, on February 14, 2019, the EPA and the Corps 
published a proposed rule that would replace the 2015 rule, and significantly reduce the waters subject to federal regulation 
under the Clean Water Act.  Such proposal is currently subject to public review and comment, after which additional legal 
challenges are anticipated.  Further, on April 23, 2019, the EPA published an interpretive statement and request for comment, 
clarifying that the Clean Water Act’s permitting program for pollutant discharges does not apply to releases of pollutants to 
groundwater. As a result of such recent developments, substantial uncertainty exists regarding the scope of waters protected 
under the Clean Water Act. To the extent the rules expand the range of properties subject to the Clean Water Act’s jurisdiction, 
certain energy companies could face increased costs and delays with respect to obtaining permits for dredge and fill activities in 
wetland areas. 

18

 
 
 
 
The EPA has also adopted regulations requiring certain oil and natural gas exploration and production facilities to 

obtain individual permits or coverage under general permits for storm water discharges. In addition, on June 28, 2016, the EPA 
published a final rule prohibiting the discharge of wastewater from onshore unconventional oil and gas extraction facilities to 
publicly owned wastewater treatment plants, which regulations are discussed in more detail below under the caption “—
Regulation of Hydraulic Fracturing.” Costs may be associated with the treatment of wastewater or developing and 
implementing storm water pollution prevention plans, as well as for monitoring and sampling the storm water runoff from 
certain of our facilities. Also, spill prevention, control and countermeasure plan requirements under federal law require 
appropriate containment berms and similar structures to help prevent the contamination of navigable waters. Some states also 
maintain groundwater protection programs that require permits for discharges or operations that may impact groundwater 
conditions. Noncompliance with these requirements may result in substantial administrative, civil and criminal penalties, as 
well as injunctive obligations.

Air Emissions. The federal Clean Air Act, as amended, and comparable state laws and regulations, regulate emissions 
of various air pollutants through the issuance of permits and the imposition of other requirements. The EPA has developed, and 
continues to develop, stringent regulations governing emissions of air pollutants at specified sources. New facilities may be 
required to obtain permits before work can begin, and existing facilities may be required to obtain additional permits and incur 
capital costs in order to remain in compliance. For example, our sand proppant services operations are subject to air permits 
issued by the Wisconsin Department of Natural Resources regulating our emission of fugitive dust and other constituents. 
These and other laws and regulations may increase the costs of compliance for some facilities where we operate, and federal 
and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with air permits or 
other requirements of the federal Clean Air Act and associated state laws and regulations. Obtaining or renewing permits has 
the potential to delay the development of oil and natural gas and infrastructure projects.

Climate Change. In recent years, federal, state and local governments have taken steps to reduce emissions of carbon 

dioxide, methane and other greenhouse gases, collectively referred to as GHGs. The EPA has finalized a series of GHG 
monitoring, reporting and emissions control rules for the oil and natural gas industry, and the U.S. Congress has, from time to 
time, considered adopting legislation to reduce emissions. Almost one-half of the states have already taken measures to reduce 
emissions of GHGs primarily through the development of GHG emission inventories and/or regional GHG cap-and-trade 
programs. While we are subject to certain federal GHG monitoring and reporting requirements, our operations currently are not 
adversely impacted by existing federal, state and local climate change initiatives. 

At the international level, in December 2015, the United States participated in the 21st Conference of the Parties of the 
United Nations Framework Convention on Climate Change in Paris, France. The resulting Paris Agreement calls for the parties 
to undertake “ambitious efforts” to limit the average global temperature, and to conserve and enhance sinks and reservoirs of 
GHGs. The Agreement went into effect on November 4, 2016. The Paris Agreement establishes a framework for the parties to 
cooperate and report actions to reduce GHG emissions. However, on June 1, 2017, President Trump announced that the United 
States would withdraw from the Paris Agreement, and begin negotiations to either re-enter or negotiate an entirely new 
agreement with more favorable terms for the United States. The Paris Agreement sets forth a specific exit process, whereby a 
party may not provide notice of its withdrawal until three years from the effective date, with such withdrawal taking effect one 
year from such notice. On November 4, 2019, the Trump Administration submitted its formal notification of withdrawal to the 
United Nations. It is not clear what steps, if any, will be taken to negotiate a new agreement, or what terms would be included 
in such an agreement. In response to the announcement, many state and local leaders have stated their intent to intensify efforts 
to uphold the commitments set forth in the international accord.

Restrictions on emissions of methane or carbon dioxide that may be imposed could adversely affect the oil and natural 

gas industry by reducing demand for hydrocarbons and by making it more expensive to develop and produce hydrocarbons, 
either of which could have a material adverse effect on future demand for our services. At this time, it is not possible to 
accurately estimate how potential future laws or regulations addressing GHG emissions would impact our business.

In addition, there have also been efforts in recent years to influence the investment community, including investment

advisors and certain sovereign wealth, pension and endowment funds promoting divestment of fossil fuel equities and 
pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel reserves. Such environmental activism 
and initiatives aimed at limiting climate change and reducing air pollution could interfere with our business activities, 
operations and ability to access capital. Furthermore, claims have been made against certain energy companies alleging that 
GHG emissions from oil and natural gas operations constitute a public nuisance under federal and/or state common law. As a 
result, private individuals or public entities may seek to enforce environmental laws and regulations against certain energy 
companies and could allege personal injury, property damages or other liabilities. While our business is not a party to any such 

19

 
 
 
 
 
 
litigation, we could be named in actions making similar allegations. An unfavorable ruling in any such case could significantly 
impact our operations and could have an adverse impact on our financial condition. 

Moreover, climate change may cause more extreme weather conditions such as more intense hurricanes, 

thunderstorms, tornadoes and snow or ice storms, as well as rising sea levels and increased volatility in seasonal temperatures. 
Extreme weather conditions can interfere with our productivity and increase our costs and damage resulting from extreme 
weather may not be fully insured. However, at this time, we are unable to determine the extent to which climate change may 
lead to increased storm or weather hazards affecting our operations.

Endangered Species Act

Environmental laws such as the Endangered Species Act, as amended, or the ESA, may impact exploration, 

development and production activities on public or private lands. The ESA provides broad protection for species of fish, 
wildlife and plants that are listed as threatened or endangered in the U.S. Similar protections are offered to migratory birds 
under the Migratory Bird Treaty Act, though, in December 2017, the U.S. Fish and Wildlife Service provided guidance limiting 
the reach of the Act. Federal agencies are required to insure that any action authorized, funded or carried out by them is not 
likely to jeopardize the continued existence of listed species or modify their critical habitat. While some of our facilities may be 
located in areas that are designated as habitat for endangered or threatened species, we believe that we are in substantial 
compliance with the ESA. The U.S. Fish and Wildlife Service may identify, however, previously unidentified endangered or 
threatened species or may designate critical habitat and suitable habitat areas that it believes are necessary for survival of a 
threatened or endangered species, which could cause us to incur additional costs or become subject to operating restrictions or 
bans in the affected areas.

Regulation of Hydraulic Fracturing

A portion of our business is dependent on our ability to conduct hydraulic fracturing and horizontal drilling activities. 

Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons, particularly 
natural gas, from tight formations, including shales. The process, which involves the injection of water, sand and chemicals 
(also called “proppants”) under pressure into formations to fracture the surrounding rock and stimulate production, is typically 
regulated by state oil and natural gas commissions. However, federal agencies have asserted regulatory authority over certain 
aspects of the process. For example, the EPA has taken the position that hydraulic fracturing with fluids containing diesel fuel is 
subject to regulation under the Underground Injection Control program, specifically as “Class II” Underground Injection 
Control wells under the Safe Drinking Water Act. In addition, on June 28, 2016, the EPA published a final rule prohibiting the 
discharge of wastewater from onshore unconventional oil and natural gas extraction facilities to publicly owned wastewater 
treatment plans. The EPA is also conducting a study of private wastewater treatment facilities (also known as centralized waste 
treatment, or CWT, facilities) accepting oil and natural gas extraction wastewater. The EPA is collecting data and information 
related to the extent to which CWT facilities accept such wastewater, available treatment technologies (and their associated 
costs), discharge characteristics, financial characteristics of CWT facilities and the environmental impacts of discharges from 
CWT facilities. Furthermore, legislation to amend the Safe Drinking Water Act, or SDWA, to repeal the exemption for 
hydraulic fracturing (except when diesel fuels are used) from the definition of “underground injection” and require federal 
permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to require disclosure of the chemical 
constituents of the fluids used in the fracturing process, were proposed in recent sessions of Congress.

On August 16, 2012, the EPA published final regulations under the federal Clean Air Act that establish new air 
emission controls for oil and natural gas production and natural gas processing operations. Specifically, the EPA’s rule package 
includes New Source Performance standards, which we refer to as NSP standards, to address emissions of sulfur dioxide and 
volatile organic compounds and a separate set of emission standards to address hazardous air pollutants frequently associated 
with oil and natural gas production and processing activities. The final rules seek to achieve a 95% reduction in volatile organic 
compounds emitted by requiring the use of reduced emission completions or “green completions” on all hydraulically-fractured 
wells constructed or refractured after January 1, 2015. The rules also establish specific new requirements regarding emissions 
from compressors, controllers, dehydrators, storage tanks and other production equipment. The EPA received numerous 
requests for reconsideration of these rules from both industry and the environmental community, and court challenges to the 
rules were also filed. In response, the EPA has issued, and will likely continue to issue, revised rules responsive to some of the 
requests for reconsideration. In particular, on May 12, 2016, the EPA amended the NSP standards to impose new standards for 
methane and VOC emissions for certain new, modified and reconstructed equipment, processes and activities across the oil and 
natural gas sector. However, in a March 28, 2017 executive order, President Trump directed the EPA to review the 2016 
regulations and, if appropriate, to initiate a rulemaking to rescind or revise them consistent with the stated policy of promoting 
clean and safe development of the nation’s energy resources, while at the same time avoiding regulatory burdens that 
unnecessarily encumber energy production. On June 16, 2017, the EPA published a proposed rule to stay for two years certain 
20

 
 
 
 
requirements of the 2016 regulations, including fugitive emission requirements. Also, on October 15, 2018, the EPA published 
a proposed rule to significantly reduce regulatory burdens imposed by the 2016 regulations, including, for example, reducing 
the monitoring frequency for fugitive emissions and revising the requirements for pneumatic pumps at well sites. In addition, 
on August 28, 2019, the EPA proposed amendments to the 2012 and 2016 New Source Performance standards to ease 
regulatory burdens, including rescinding standards applicable to transmission or storage segments and eliminating methane 
requirements altogether. Legal challenges are anticipated and thus substantial uncertainty exists regarding the scope of New 
Source Performance standards for oil and natural gas operations. The New Source Performance standards, to the extent 
implemented, as well as any future laws and their implementing regulations, may require us to obtain pre-approval for the 
expansion or modification of existing facilities or the construction of new facilities expected to produce air emissions, impose 
stringent air permit requirements, or mandate the use of specific equipment or technologies to control emissions. We cannot 
predict the final regulatory requirements or the cost to comply with such requirements with any certainty.

In addition, on March 26, 2015, the Bureau of Land Management, or BLM, published a final rule governing hydraulic 

fracturing on federal and Indian lands. The rule requires public disclosure of chemicals used in hydraulic fracturing, 
implementation of a casing and cementing program, management of recovered fluids, and submission to the BLM of detailed 
information about the proposed operation, including wellbore geology, the location of faults and fractures, and the depths of all 
usable water. Also, on November 15, 2016, the BLM finalized a waste prevention rule to reduce the flaring, venting and leaking 
of methane from oil and gas operations on federal and Indian lands. The rule requires operators to use currently available 
technologies and equipment to reduce flaring, periodically inspect their operations for leaks, and replace outdated equipment 
that vents large quantities of gas into the air. The rule also clarifies when operators owe the government royalties for flared gas. 
On March 28, 2017, President Trump signed an executive order directing the BLM to review the above rules and, if 
appropriate, to initiate a rulemaking to rescind or revise them. Accordingly, on December 29, 2017, the BLM published a final 
rule to rescind the 2015 hydraulic fracturing rule; however, a coalition of environmentalists, tribal advocates and the State of 
California filed lawsuits challenging the rule rescission. Also, on April 4, 2018, a federal district court stayed certain provisions 
of the waste prevention rule and, on September 28, 2018, the BLM finalized revisions to the rule to reduce “unnecessary 
compliance burdens.” The States of California and New Mexico have challenged the scaled-back rule. At this time, it is 
uncertain when, or if, the rules will be implemented, and what impact they would have on our operations.

There are certain governmental reviews either underway or being proposed that focus on the environmental aspects of 

hydraulic fracturing practices. On December 13, 2016, the EPA released a study examining the potential for hydraulic 
fracturing activities to impact drinking water resources, finding that, under some circumstances, the use of water in hydraulic 
fracturing activities can impact drinking water resources. Also, on February 6, 2015, the EPA released a report with findings 
and recommendations related to public concern about induced seismic activity from disposal wells. The report recommends 
strategies for managing and minimizing the potential for significant injection-induced seismic events. Other governmental 
agencies, including the U.S. Department of Energy, the U.S. Geological Survey, and the U.S. Government Accountability 
Office, have evaluated or are evaluating various other aspects of hydraulic fracturing. These ongoing or proposed studies, 
depending on their degree of pursuit and whether any meaningful results are obtained, could spur initiatives to further regulate 
hydraulic fracturing, and could ultimately make it more difficult or costly for us to perform fracturing and increase our costs of 
compliance and doing business. 

Several states and local jurisdictions in which we or our customers operate have adopted or are considering adopting 

regulations that could restrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating 
standards and/or require the disclosure of the composition of hydraulic fracturing fluids. Any increased regulation of hydraulic 
fracturing could reduce the demand for our services and materially and adversely affect our reserves and results of operations.

There has been increasing public controversy regarding hydraulic fracturing with regard to the use of fracturing fluids, 

induced seismic activity, impacts on drinking water supplies, use of water and the potential for impacts to surface water, 
groundwater and the environment generally. A number of lawsuits and enforcement actions have been initiated across the 
country implicating hydraulic fracturing practices. If new laws or regulations that significantly restrict hydraulic fracturing are 
adopted, such laws could make it more difficult or costly for us to perform fracturing to stimulate production from tight 
formations as well as make it easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings 
based on allegations that specific chemicals used in the fracturing process could adversely affect groundwater. In addition, if 
hydraulic fracturing is further regulated at the federal, state or local level, our customers’ fracturing activities could become 
subject to additional permitting and financial assurance requirements, more stringent construction specifications, increased 
monitoring, reporting and recordkeeping obligations, plugging and abandonment requirements and also to attendant permitting 
delays and potential increases in costs. Such legislative or regulatory changes could cause us or our customers to incur 
substantial compliance costs, and compliance or the consequences of any failure to comply by us could have a material adverse 
effect on our financial condition and results of operations. At this time, it is not possible to estimate the impact on our business 
of newly enacted or potential federal, state or local laws governing hydraulic fracturing.

Regulation of Sand Proppant Services

The MSHA has primary regulatory jurisdiction over commercial silica operations, including quarries, surface mines, 
underground mines and industrial mineral processing facilities. MSHA representatives perform at least two annual inspections 
of our production facilities to ensure employee and general site safety. To date, these inspections have not resulted in any 
citations for material violations of MSHA standards, and we believe we are in material compliance with MSHA requirements.

Other Regulation of the Oil and Natural Gas Industry

The oil and natural gas industry is extensively regulated by numerous federal, state and local authorities. Legislation 

affecting the oil and natural gas industry is under constant review for amendment or expansion, frequently increasing the 
regulatory burden. Also, numerous departments and agencies, both federal and state, are authorized by statute to issue rules and 
regulations that are binding on the oil and natural gas industry and its individual members, some of which carry substantial 
penalties for failure to comply. Although changes to the regulatory burden on the oil and natural gas industry could affect the 
demand for our services, we would not expect to be affected any differently or to any greater or lesser extent than other 
companies in the industry with similar operations.

Drilling. Our operations are subject to various types of regulation at the federal, state and local level. These types of 
regulation include requiring permits for the drilling of wells, drilling bonds and reports concerning operations. The states, and 
some counties and municipalities, in which we operate also regulate one or more of the following:

• 
• 
• 
• 
• 
• 

the location of wells;
the method of drilling and casing wells;
the timing of construction or drilling activities, including seasonal wildlife closures;
the surface use and restoration of properties upon which wells are drilled;
the plugging and abandoning of wells; and
notice to, and consultation with, surface owners and other third parties.

Federal, state and local regulations provide detailed requirements for the plugging and abandonment of wells, closure 

or decommissioning of production facilities and pipelines and for site restoration in areas where we operate. Although the 
Corps does not require bonds or other financial assurances, some state agencies and municipalities do have such requirements.

State Regulation. The states in which we or our customers operate regulate the drilling for, and the production and 

gathering of, oil and natural gas, including through requirements relating to the method of developing new fields, the spacing 
and operation of wells and the prevention of waste of oil and natural gas resources. States may also regulate rates of production 
and may establish maximum daily production allowables from oil and natural gas wells based on market demand or resource 
conservation, or both. States do not regulate wellhead prices or engage in other similar direct economic regulation, but they 
may do so in the future. The effect of these regulations may be to limit the amount of oil and natural gas that may be produced 
from wells and to limit the number of wells or locations our customers can drill.

The Ohio Department of Natural Resources, or the ODNR, has enacted a comprehensive set of rules to regulate the 
construction of well pads. Under these new rules, operators must submit detailed horizontal well pad site plans certified by a 
professional engineer for review by the ODNR Division of Oil and Gas Resources Management prior to the construction of a 
well pad. These rules have resulted in increased construction costs for operators. Also, on November 20, 2018, Ohio EPA 
announced that it intends to develop new rules that would cover air pollution emissions associated with non-conventional oil 
and gas facilities.

The petroleum industry is also subject to compliance with various other federal, state and local regulations and laws. 

Some of those laws relate to resource conservation and equal employment opportunity. We do not believe that compliance with 
these laws will have a material adverse effect on us.

OSHA Matters

We are also subject to the requirements of the federal Occupational Safety and Health Act, or OSHA, and comparable 

state statutes that regulate the protection of the health and safety of workers. In addition, the OSHA hazard communication 
standard requires that information be maintained about hazardous materials used or produced in operations and that this 
information be provided to employees, state and local government authorities and the public. Compliance with these laws and 
regulations has not had a material adverse effect on our operations or financial position.

Employees

As of December 31, 2019, we had 1,607 full time employees. None of our employees are represented by labor unions 

or covered by any collective bargaining agreements. We also hire independent contractors and consultants involved in land, 
technical, regulatory and other disciplines to assist our full time employees.

Item 1A. Risk Factors 

Risks Related to Our Business and the Industries We Serve

Our customer base is concentrated and the loss of one or more of our significant customers, or their failure to pay the 
amounts they owe us, could cause our revenue to decline substantially.

Our top five customers accounted for approximately 53% and 77%, respectively, of our revenue for the years ended 

December 31, 2019 and 2018. Gulfport was our largest customer for the year ended December 31, 2019 accounting for 
approximately 20% of our revenue and our second largest customer for the year ended December 31, 2018 accounting for 
approximately 8% of our revenue. PREPA was our second largest customer for the year ended December 31, 2019 accounting 
for approximately 15% of our revenue and our largest customer for the year ended December 31, 2018 accounting for 
approximately 60% of our revenue. It is likely that we will continue to derive a significant portion of our revenue from a 
relatively small number of customers in the future. If a major customer decided not to continue to use our services, our revenue 
would decline and our operating results and financial condition could be harmed. In this regard, Gulfport is seeking to 
terminate our pressure pumping contract with it and our work for PREPA ended on March 31, 2019. See the risk factors below 
for additional information. In addition, we are subject to credit risk due to the concentration of our customer base. In particular, 
as of December 31, 2019, PREPA owed us approximately $227 million for services performed excluding $42 million of interest 
charged on these delinquent balances as of December 31, 2019. Any nonperformance by our counterparties, including their 
failure to pay the amounts they owe us on a timely basis or at all, either as a result of changes in financial and economic 
conditions or otherwise, could have a material adverse impact on our operating results and could adversely affect our liquidity. 

Cobra, one of our infrastructure services subsidiaries, was party to service contracts with PREPA. PREPA is currently 
subject to bankruptcy proceedings, which were filed in July 2017 and are currently 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 contracts is largely 
dependent upon funding from the Federal Emergency Management Agency or other sources. In the event that PREPA (i) 
does not have or does not obtain the funds necessary to satisfy its payment obligations to our subsidiary under the contracts, 
(ii) obtains the necessary funds but refuses to pay the amounts owed to us or (iii) otherwise does not pay amounts owed to us 
for services performed, our financial condition, results of operations and cash flows would be materially and adversely 
affected.

On October 19, 2017, one of our subsidiaries, Cobra, and PREPA entered into an emergency master services 
agreement for repairs to PREPA’s electrical grid as a result of Hurricane Maria. The one-year contract, as amended, provided 
for payments of up to $945 million. On May 26, 2018, Cobra and PREPA entered into a second one-year, $900 million master 
services agreement to provide additional repair services and begin the initial phase of reconstruction of the electrical power 
system in Puerto Rico. As of December 31, 2019, PREPA owed us approximately $227 million for services performed 
excluding $42 million of interest charged on these delinquent balances as of December 31, 2019. 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 contracts is largely dependent upon funding from the Federal Emergency Management 
Agency or other sources. On September 30, 2019, we filed a motion with the U.S. District Court for the District of Puerto Rico 
seeking recovery of the amounts owed to us by PREPA. PREPA filed a motion to stay our motion on the ground that the 
ongoing criminal proceedings described in the immediately following risk factor below against the former president of Cobra 
and two other individuals may affect our recovery of those amounts. On October 17, 2019, the court granted PREPA’s request 
to stay our motion and, on February 3, 2020, extended the stay until a status conference to be held on June 17, 2020. In the 

23

 
 
 
event PREPA (i) does not have or does not obtain the funds necessary to satisfy its obligations to Cobra under the contracts, (ii) 
obtains the necessary funds but refuses to pay the amounts owed to us or (iii) otherwise does not pay amounts owed to us for 
services performed, the receivable may not be collected and our financial condition, results of operations and cash flows would 
be materially and adversely affected. Further, as noted above, our contracts with PREPA have concluded and we have not 
obtained, and there can be no assurance that we will be able to obtain, one or more contracts with PREPA or other customers to 
replace the level of services that we provided to PREPA under our previous contracts.

The outcomes of investigations and litigation relating to our contracts with PREPA may have a material adverse effect on 
our business, financial condition, results of operations and cash flows.

On September 10, 2019, the U.S. District Court for the District of Puerto Rico unsealed an indictment that charged the 

former president of Cobra with conspiracy, wire fraud, false statements and disaster fraud. Two other individuals were also 
charged in the indictment. The indictment is focused on the interactions between a former FEMA official and the former 
President of Cobra. Neither we nor any of our subsidiaries were charged in the indictment. We are continuing to cooperate with 
the related investigation. Subsequent to the indictment, we received (i) a preservation request letter from the Securities and 
Exchange Commission related to documents relevant to an ongoing investigation it is conducting and (ii) a civil investigative 
demand, or CID, from the United States Department of Justice, or DOJ, requesting certain documents and answers to 
interrogatories relevant to an ongoing investigation DOJ is conducting. Both the SEC and DOJ investigations relate to the same 
subjects as those at issue in the criminal matter referenced above. We are cooperating with both the SEC and DOJ. Given the 
uncertainty inherent in the criminal proceeding and the SEC and DOJ investigations, it is not possible at this time to determine 
the potential outcome or other potential impacts that they will have on us. Further, government contracts are subject to various 
uncertainties, restrictions and regulations, including oversight audits and compliance reviews by government agencies and 
representatives. Accordingly, it is possible that additional investigations may arise in the future.

In June 2019 and August 2019, we were served with three class action lawsuits filed in the Western District of 

Oklahoma which, on September 13, 2019, were consolidated under the case caption In re Mammoth Energy Services, Inc. 
Securities Litigation. On November 12, 2019, the plaintiffs filed their first amended complaint against us, our Chief Executive 
Officer and our Chief Financial Officer. Pursuant to their first amended complaint, the plaintiffs brought a consolidated putative 
federal securities class action on behalf of all investors who purchased or otherwise acquired our common stock between 
October 19, 2017 and June 5, 2019. On January 10, 2020, the defendants filed their motion to dismiss the first amended 
complaint.  

In September 2019, four derivative lawsuits were filed, two in the Western District of Oklahoma and two in the 
District of Delaware, purportedly on behalf of the company and against its officers and directors. In October 2019, the plaintiffs 
in the two Oklahoma actions voluntarily dismissed their respective cases, with one plaintiff refiling his action in the District of 
Delaware. On September 13, 2019, the Delaware court consolidated the three actions under the case caption In re Mammoth 
Energy Services, Inc. Consolidated Shareholder Litigation. On January 17, 2020, the plaintiffs filed their consolidated amended 
shareholder derivative complaint on behalf of nominal defendant, Mammoth Energy Services, Inc., and against our Chief 
Executive Officer, Chief Financial Officer, members of our board of directors, Gulfport and Wexford. On February 18, 2020, 
the defendants filed a motion to stay this action.

On January 21, 2020, Mastec Renewables Puerto Rico, LLC, or Mastec, filed a lawsuit against us and Cobra in the 

U.S. District Court in the Southern District of Florida. In its complaint, Mastec asserts claims against us and Cobra for 
violations of the federal Racketeer Influenced and Corrupt Organizations Act, tortious interference and violations of Puerto 
Rico state laws. Mastec alleges that it sustained injuries to its business and property in the amount of $500 million because of 
our and Cobra’s wrongful interference, payment of bribes and other inducement to a FEMA official in order to secure two 
infrastructure contracts to aid in the rebuilding of the energy infrastructure in Puerto Rico after Hurricane Maria.

We believe that the plaintiffs’ claims in the above referenced actions are without merit and will vigorously defend the 
actions. However, at this time, we are not able to predict the outcome of the investigations and lawsuits. If one or more of the 
investigations and lawsuits is determined adversely to us, it could have a material adverse effect on our business, financial 
condition, results of operations and cash flows.

Opportunities associated with government contracts could lead to increased governmental regulation applicable to us.

Most government contracts are awarded through a regulated competitive bidding process. If we are successful in being 

awarded government contracts, significant costs could be incurred by us before any revenues were realized from these 
contracts. Government agencies may review a contractor’s performance, cost structure and compliance with applicable laws, 
regulations and standards. If government agencies determine through these reviews that costs were improperly allocated to 

24

 
specific contracts, they will not reimburse the contractor for those costs or may require the contractor to refund previously 
reimbursed costs. If government agencies determine that we engaged in improper activity, we may be subject to civil and 
criminal penalties. Government contracts are also subject to renegotiation of profit and termination by the government prior to 
the expiration of the term. See the two preceding risk factors for information regarding pending investigations and legal 
proceedings relating to our contracts with PREPA.

We provide our hydraulic fracturing completion services to a limited number of customers, and Gulfport, one of our 
customers, is seeking to terminate its agreement with us, which could adversely affect our operations.

We provide completion services, which services include hydraulic fracturing. A portion of our revenue from this 

business is derived from Gulfport pursuant to a contract that expires in December 2021. On December 28, 2019, Gulfport filed 
a lawsuit alleging our breach of this contract and is seeking to terminate the contract and recover damages for alleged 
overpayments, audit costs and legal fees. We believe this action is without merit and will vigorously defend the lawsuit. 
However, we cannot assure you that we will be able to preserve, extend or renew our contract with Gulfport on favorable terms 
and conditions or at all. Likewise, we cannot assure you that we would be able to obtain replacement long-term contracts with 
other customers sufficient to continue providing the level of services that we currently provide to Gulfport. The termination of 
our relationship or nonrenewal of our contract with Gulfport, or one or more of our other customers, could have a material 
adverse effect on our business, financial condition, results of operations and cash flows.

We provide natural sand proppant to a limited number of customers, and the termination of one or more of these 
relationships could adversely affect our operations.

We provide natural sand proppant used for hydraulic fracturing. Historically, we have derived a large portion of our 

revenue from this business from Gulfport pursuant to a contract that expires in December 2021. The termination of our 
relationship or nonrenewal of our contract with Gulfport, or one or more of our other customers, could have a material adverse 
effect on our business, financial condition, results of operations and cash flows.

Our revolving credit facility imposes, and any of our future credit facilities may impose, restrictions on us that may affect 
our ability to successfully operate our business.

Our revolving credit facility limits, and any of our future credit facilities may limit, our ability to take various actions, 

such as:

entering into transactions with affiliates;

incurring additional indebtedness;
paying dividends;
creating certain additional liens on our assets;
entering into sale and leaseback transactions;

• 
• 
• 
• 
•  making investments;
• 
•  making material changes to the type of business we conduct or our business structure;
•  making guarantees;
• 
• 
•  merging or consolidating with other entities; and 
selling all or substantially all of our assets.
• 

entering into hedges;
disposing of assets in excess of certain permitted amounts;

As of December 31, 2019, our revolving credit facility contained various customary affirmative and restrictive 
covenants. Among the covenants were two financial covenants, a minimum interest coverage ratio (3.0 to 1.0) and a maximum 
leverage ratio (4.0 to 1.0). As of December 31, 2019, we were in compliance with the financial covenants under our revolving 
credit facility. However, we believe that our adjusted EBITDA for the trailing four fiscal quarters would have resulted in a 
breach of the maximum leverage ratio and/or the interest coverage ratio as early as the end of the first quarter of 2020 if we did 
not receive payments due from PREPA before the end of such quarter. As we believe that such payments from PREPA are 
unlikely to be received by March 31, 2020, on February 26, 2020, we amended our revolving credit facility to, among other 
things, (i) amend our financial covenants, as outlined below, (ii) decrease the maximum revolving advance amount from $185 
million to $130 million, (iii) decrease the amount that the maximum revolving advance can be increased to (the accordion) 
from $350 million to $180 million, (iv) increase the applicable margin ranges from 2.00% to 2.50% per annum in the case of 
the alternate base rate and from 3.00% to 3.50% per annum in the case of LIBOR, (v) increase the aggregate amount of 
permitted asset dispositions, and (vi) permit certain sale-leaseback transactions.

25

 
 
 
 
The financial covenants under our revolving credit facility were amended as follows:

the minimum interest coverage ratio of 3.0 to 1.0 was eliminated;

the maximum leverage coverage ratio of 4.0 to 1.0 was eliminated for the first two fiscal quarters of 2020 and, 
beginning with the fiscal quarter ended September 30, 2020, changed to 2.5 to 1.0;
beginning with the fiscal quarter ended September 30, 2020, a minimum fixed charge coverage ratio of at least 1.1 to 
1.0 was added; and
from the effective date of February 26, 2020 through September 30, 2020, a minimum excess availability covenant of 
10% of the maximum revolving advance amount was added.

We cannot assure you that we will be able to remain in compliance with the covenants contained in our revolving 

credit facility as amended and restated. If an event of default occurs under our revolving credit facility and remains uncured, it 
could have a material adverse affect on our business, financial condition, results of operations and cash flows. The lenders (i) 
would not be required to lend any additional amounts to us, (ii) could elect to declare all outstanding borrowings, together with 
accrued and unpaid interest and fees, to be due and payable, and (iii) may have the ability to require us to apply all of our 
available cash to repay our outstanding borrowings. 

Our failure to receive payment for contract change orders or adequately recover on claims brought by us against customers 
related to payment terms and costs could materially and adversely affect our financial position, results of operations and 
cash flows.

We have in the past brought, and may in the future bring, claims against our customers related to, among other things, 
the payment terms of our contracts and change orders relating to such contracts. These types of claims can occur due to, among 
other things, customer-caused delays or changes in project scope, both of which may result in additional costs. In some 
instances, these claims can be the subject of lengthy legal proceedings, and it is difficult to predict the timing and outcome of 
such proceedings. Our failure to promptly and adequately recover on these types of claims could have an adverse impact on our 
financial condition, results of operations and cash flows.

Competition within the energy services industry may adversely affect our ability to market our services.

The energy services industry is highly competitive and fragmented and includes numerous small companies capable of 
competing effectively in our markets on a local basis, as well as large companies that possess substantially greater financial and 
other resources than we do. Our larger competitors’ greater resources could allow those competitors to compete more 
effectively than we can. The amount of equipment available may exceed demand, which could result in active price 
competition. Many contracts are awarded on a bid basis, which may further increase competition based primarily on price. In 
addition, adverse market conditions lower demand for well servicing equipment, which results in excess equipment and lower 
utilization rates. If market conditions in our oil and natural gas-oriented operating areas persist, utilization rates may decline.

We may not accurately estimate the costs associated with infrastructure services provided under fixed price contracts, which 
could have an adverse effect on our financial condition, results of operations and cash flows.

We derive a portion of our infrastructure services revenue from fixed-price master service and other service 
agreements. Under these contracts, we typically set the price of our services on a per unit or aggregate basis and assume the 
risk that costs associated with our performance may be greater than what we estimated. In addition to master service and other 
service agreements, we enter into contracts for specific projects or jobs that may require the installation or construction of an 
entire infrastructure system or specified units within an infrastructure system, which are priced on a per unit basis. Profitability 
will be reduced if actual costs to complete a project exceed our original estimates. Our profitability is dependent upon our 
ability to accurately estimate the costs associated with our services and our ability to execute in accordance with our plans. A 
variety of factors could negatively affect these costs, such as lower than anticipated productivity, conditions at work sites 
differing materially from those anticipated at the time we bid on the contract and higher than expected costs of materials and 
labor. These variations, along with other risks inherent in performing fixed price contracts, could cause actual project revenue 
and profits to differ from original estimates, which could result in lower margins than anticipated, or losses, which could reduce 
our profitability, cash flows and liquidity.

We may be unable to obtain sufficient bonding capacity to support certain service offerings, and the need for performance 
and surety bonds could reduce availability under our credit facility.

Some of our infrastructure services contracts require performance and payment bonds. If we are not able to renew or 
obtain a sufficient level of bonding capacity in the future, we may be precluded from being able to bid for certain contracts or 
26

 
 
 
 
 
 
successfully contract with certain customers. In addition, even if we are able to successfully renew or obtain performance or 
payment bonds, we may be required to post letters of credit in connection with the bonds, which would reduce availability 
under our credit facility. Furthermore, under standard terms in the surety market, sureties issue bonds on a project-by-project 
basis and can decline to issue bonds at any time or require the posting of additional collateral as a condition to issuing or 
renewing any bonds. If we were to experience an interruption or reduction in the availability of bonding capacity as a result of 
these or any other reasons, we may be unable to compete for or work on projects that require bonding.

The nature of our infrastructure services business exposes us to potential liability for warranty claims and faulty 
engineering, which may reduce our profitability.

Under some of our infrastructure services contracts with customers, we provide a warranty for the services we 

provide, guaranteeing the work performed against defects in workmanship and material. As much of the work we perform is 
inspected by our customers for any defects in construction prior to acceptance of the project, we have not historically incurred 
warranty claims. Additionally, materials used in construction are often provided by the customer or are warranted against 
defects from the supplier. However, certain projects may have longer warranty periods and include facility performance 
warranties that may be broader than the warranties we generally provide. In these circumstances, if warranty claims occurred, it 
could require us to re-perform the services or to repair or replace the warranted item, at a cost to us, and could also result in 
other damages if we are not able to adequately satisfy our warranty obligations. In addition, we may be required under 
contractual arrangements with our customers to warrant any defects or failures in materials we provide that we purchase from 
third parties. While we generally require suppliers to provide us warranties that are consistent with those we provide to the 
customers, if any of these suppliers default on their warranty obligations to us, we may incur costs to repair or replace the 
defective materials for which we are not reimbursed. Costs incurred as a result of warranty claims could adversely affect our 
financial condition, results of operations and cash flows.

Our infrastructure services business involves professional judgments regarding the planning, design, development, 

construction, operations and management of electric power transmission and commercial construction. Because our projects are 
often technically complex, our failure to make judgments and recommendations in accordance with applicable professional 
standards, including engineering standards, could result in damages. While we do not generally accept liability for 
consequential damages, and although we have adopted a range of insurance, risk management and risk avoidance programs 
designed to reduce potential liabilities, a significantly adverse or catastrophic event at one of our project sites or completed 
projects resulting from the services we have performed could result in significant warranty, professional liability, or other 
claims against us as well as reputational harm, especially if public safety is impacted. These liabilities could exceed our 
insurance limits or could impact our ability to obtain insurance in the future. In addition, customers, subcontractors or suppliers 
who have agreed to indemnify us against any such liabilities or losses might refuse or be unable to pay us. An uninsured claim, 
either in part or in whole, if successful and of a material magnitude, could have a substantial impact on our business, financial 
condition, results of operations and cash flows.

The timing of new contracts and termination of existing contracts may result in unpredictable fluctuations in our cash flows 
and financial results.

A substantial portion of our continental United States-based infrastructure services revenue is derived from project-

based work that is awarded through a competitive bid process. It is generally very difficult to predict the timing and geographic 
distribution of the projects that we will be awarded. The selection of, timing of, or failure to obtain projects, delays in awards of 
projects, the re-bidding or termination of projects due to budget overruns, cancellations of projects or delays in completion of 
contracts could result in the under-utilization of our assets, which could lower our overall profitability and reduce our cash 
flows. Even if we are awarded contracts, we face additional risks that could affect whether, or when, work will begin. This can 
present difficulty in matching workforce size and equipment location with contract needs. In some cases, we may be required to 
bear the cost of a ready workforce and equipment that is larger than necessary, which could impact our cash flow, expenses and 
profitability. If an expected contract award or the related work release is delayed or not received, we could incur substantial 
costs without receipt of any corresponding revenues. Moreover, construction projects for which our services are contracted may 
require significant expenditures by us prior to receipt of relevant payments from the customer. Finally, the winding down or 
completion of work on significant projects that were active in previous periods will reduce our revenue and earnings if such 
significant projects have not been replaced in the current period.

Many of our contracts may be canceled upon short notice, typically 30 to 90 days, even if we are not in default under 
the contract, and we may be unsuccessful in replacing our contracts if they are canceled or as they are completed or expire. We 
could experience a decrease in our revenue, net income and liquidity if contracts are canceled and if we are unable to replace 
canceled, completed or expired contracts. Certain of our infrastructure services customers assign work to us on a project-by-
project basis under MSAs. Under these agreements, our customers often have no obligation to assign a specific amount of work 

27

 
 
 
 
to us. Our operations could decline significantly if the anticipated volume of work is not assigned to us or is canceled. Many of 
our contracts, including our MSAs, are opened to competitive bid at the expiration of their terms. There can be no assurance 
that we will be the successful bidder on our existing contracts that come up for re-bid.

Timing of revenue for our infrastructure services backlog can be subject to change as a result of our delays, customer 
delays, regulatory delays or other factors. These changes could cause estimated revenue to be realized in periods later than 
originally expected, or not at all.  As a result, our backlog as of any particular date is an uncertain indicator of future 
revenue and earnings.

Estimated backlog for our infrastructure services represents the amount of revenue we expect to realize over the next 
36 months from future work on uncompleted construction projects, including new contracts under which work has not begun.  
Our estimated backlog also includes amounts payable to us under master service and other service agreements. Estimated 
infrastructure services backlog for work under master service and other service agreements is determined based on historical 
trends, experience from similar projects and estimates of customer demand based on communications with our customers.  As 
of December 31, 2019, our infrastructure services backlog was $490 million. In 2020, we expect to realize approximately $148 
million of our backlog. However, approximately $479 million of our infrastructure services backlog as of December 31, 2019 is 
attributable to amounts under master service or other service agreements pursuant to which our customers are not contractually 
committed to purchase a minimum amount of services. Most of these agreements can be canceled on short or no advance 
notice. Timing of revenue for our infrastructure services backlog can be subject to change as a result of our delays, customer 
delays, regulatory delays or other factors. These changes could cause estimated revenue to be realized in periods later than 
originally expected, or not at all. We occasionally experience postponements, cancellations and reductions in expected future 
work from master service agreements or other service agreements due to changes in our customers’ spending plans, market 
volatility, governmental funding and regulatory factors. There can be no assurance as to our customers’ requirements or the 
accuracy of our estimates. As a result, our backlog as of any particular date is an uncertain indicator of future revenue and 
earnings.

Backlog is not a term recognized under accounting principles generally accepted in the United States; however, it is a 

common measurement used in the infrastructure industry. As such, our methodology for determining backlog may not be 
comparable to the methodologies used by others.   

Delays and reductions in government appropriations can negatively impact energy infrastructure construction, maintenance 
and repair projects and may impair the ability of our energy infrastructure customers to timely pay for products or services 
provided or result in their insolvency or bankruptcy, any of which exposes us to credit risk of our infrastructure customers.  

Many of our infrastructure customers derive funding from federal, state and local bodies.  Delayed or reduced 
appropriations may cancel, curtail or delay projects and may have an adverse effect on our business, results of operations, cash 
flows and financial condition.

A portion of our business depends on the oil and natural gas industry and particularly on the level of exploration and 
production activity within the United States and Canada, and the ongoing volatility in prices for oil and natural gas has had, 
and continues to have, an adverse effect on our revenue, cash flows, profitability and growth.

Demand for our oil and natural gas products and services depends substantially on the level of expenditures by 

companies in the oil and natural gas industry. Throughout 2019 oil prices fluctuated between a low of $45.41 on January 1, 
2019 and a high of $66.30 on April 23, 2019, averaged $57.03 per barrel. Certain factors related to world politics and major oil 
producers caused fluctuations in the oil price during 2019. However, overall, the price of oil stayed relatively stable throughout 
the year. 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. We experienced a weakening 
in demand for our oilfield services beginning in the third quarter of 2019 which continued throughout the fourth quarter of 
2019 as a result of budget exhaustion and capital discipline from our customers. While we still expect commodity prices to be 
the primary driver of capex spending and industry activity levels in the future, other factors, such as debt repayment obligations 
and limited access to the capital markets, may play a significant role in the ultimate level of capex spend by the companies that 
use our completion and production, natural sand proppant and contract land and directional drilling service lines. Industry 
conditions are dynamic and the weakening of commodity prices from current levels may result in a material adverse impact on 
certain of our customers’ liquidity and financial position resulting in spending reductions, delays in the collection of amounts 
owing to us and similar impacts. These conditions, and others, have had and may continue to have an adverse impact on our 
financial condition, results of operations and cash flows, and it is difficult to predict how long the current commodity price 
environment will continue.

28

 
 
   
 
Many factors over which we have no control affect the supply of and demand for, and our customers’ willingness to 

explore, develop and produce oil and natural gas, and therefore, influence prices for our products and services, including:

• 

• 
• 
• 
• 
• 
• 
• 

the domestic and foreign supply of and demand for oil and natural gas;
the level of prices, and expectations about future prices, of oil and natural gas;
the level of global oil and natural gas exploration and production;
the cost of exploring for, developing, producing and delivering oil and natural gas;
the expected decline rates of current production;
the price and quantity of foreign imports;
political and economic conditions in oil producing countries, including the Middle East, Africa, South America 
and Russia;
the ability of members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price 
and production controls;
• 
speculative trading in crude oil and natural gas derivative contracts;
• 
the level of consumer product demand;
• 
the discovery rates of new oil and natural gas reserves;
• 
contractions in the credit market;
• 
the strength or weakness of the U.S. dollar;
• 
available pipeline and other transportation capacity;
the levels of oil and natural gas storage;
• 
•  weather conditions and other natural disasters;
• 
• 
• 
• 

political instability in oil and natural gas producing countries;
domestic and foreign tax policy;
domestic and foreign governmental approvals and regulatory requirements and conditions;
the continued threat of terrorism and the impact of military and other action, including military action in the 
Middle East;
technical advances affecting energy consumption;
the proximity and capacity of oil and natural gas pipelines and other transportation facilities;
the price and availability of alternative fuels;
the ability of oil and natural gas producers to raise equity capital and debt financing;
global or national health concerns, including the outbreak of pandemic or contagious diseases such as the 
coronavirus;

• 
• 
• 
• 
• 

•  merger and divestiture activity among oil and natural gas producers; and
• 

overall domestic and global economic conditions.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas 

price movements with any certainty. Any of the above factors could impact the level of oil and natural gas exploration and 
production activity and could ultimately have a material adverse effect on our business, financial condition, results of 
operations and cash flows. Further, future weakness in commodity prices could impact our business going forward, and we 
could encounter difficulties such as an inability to access needed capital on attractive terms or at all, recognizing asset 
impairment charges, an inability to meet financial ratios contained in our debt agreements, a need to reduce our capital 
spending and other similar impacts.

The cyclicality of the oil and natural gas industry may cause our operating results to fluctuate.

We derive a portion of our revenues from companies in the oil and natural gas exploration and production industry, a 
historically cyclical industry with levels of activity that are significantly affected by the levels and volatility of oil and natural 
gas prices. We have, and may in the future, experience significant fluctuations in operating results as a result of the reactions of 
our customers to changes in oil and natural gas prices. For example, prolonged low commodity prices experienced by the oil 
and natural gas industry during 2015 and the first part of 2016 and again in the fourth quarter of 2018, combined with adverse 
changes in the capital and credit markets, caused many exploration and production companies to reduce their capital budgets 
and drilling activity. This resulted in a significant decline in demand for oilfield services and adversely impacted the prices 
oilfield services companies could charge for their services. In addition, a majority of the service revenue we earn is based upon 
a charge for a relatively short period of time (e.g., an hour, a day, a week) for the actual period of time the service is provided to 
our customers. By contracting services on a short-term basis, we are exposed to the risks of a rapid reduction in market prices 
and utilization, with resulting volatility in our revenues.

29

 
 
 
 
If oil prices or natural gas prices decline, the demand for our oil and natural gas services could be adversely affected.

The demand for our oil and natural gas services is primarily determined by current and anticipated oil and natural gas 

prices and the related general production spending and level of drilling activity in the areas in which we have operations. 
Volatility or weakness in oil prices or natural gas prices (or the perception that oil prices or natural gas prices will decrease) 
affects the spending patterns of our customers and may result in the drilling of fewer new wells or lower production spending 
on existing wells. This, in turn, could result in lower demand for our services and may cause lower rates and lower utilization 
of our well service equipment. 

Any future decline in oil and gas prices could materially affect the demand for our services. Prices for oil and natural 

gas historically have been extremely volatile and are expected to continue to be volatile in the years to come. During 2019, 
West Texas Intermediate posted prices ranged from $45.41 to $66.30 per barrel and the New York Mercantile Exchange natural 
gas futures prices ranged from $2.07 to $3.59 per MMBtu. If the prices of oil and natural gas decline from current levels, our 
operations, financial condition and level of expenditures may be materially and adversely affected.

Deterioration of the commodity price environment can negatively impact oil and natural gas exploration and production 
companies and, in some cases, impair their ability to timely pay for products or services provided or result in their 
insolvency or bankruptcy, any of which exposes us to credit risk of our oil and natural gas exploration and production 
customers.

In weak economic and commodity price environments, we may experience increased difficulties, delays or failures in 

collecting outstanding receivables from our customers, due to, among other reasons, a reduction in their cash flow from 
operations, their inability to access the credit markets and, in certain cases, their insolvencies. Such increases in collection 
issues could have a material adverse effect on our business, results of operations, cash flows and financial condition. We cannot 
assure you that the reserves we have established for potential credit losses will be sufficient to meet write-offs of uncollectible 
receivables or that our losses from such receivables will be consistent with our expectations. To the extent one or more of our 
key customers commences bankruptcy proceedings, our contracts with these customers may be subject to rejection under 
applicable provisions of the United States Bankruptcy Code, or may be renegotiated. Further, during any such bankruptcy 
proceeding, prior to assumption, rejection or renegotiation of such contracts, the bankruptcy court may temporarily authorize 
the payment of value for our services less than contractually required, which could also have a material adverse effect on our 
business, results of operations, cash flows and financial condition.

Shortages, delays in delivery and interruptions in supply of drill pipe, replacement parts, other equipment, supplies and 
materials may adversely affect our contract land and directional drilling business or our pressure pumping business.

During periods of increased demand for drilling and completion services, the industry has experienced shortages of 

drill pipe, replacement parts, other equipment, supplies and materials, including, in the case of our pressure pumping 
operations, replacement parts, other equipment, proppants, acid, gel and water. These shortages can cause the price of these 
items to increase significantly and require that orders for the items be placed well in advance of expected use. In addition, any 
interruption in supply could result in significant delays in delivery of equipment and materials or prevent operations. 
Interruptions may be caused by, among other reasons:

•  weather issues, whether short-term such as a hurricane, or long-term such as a drought; and
• 

shortage in the number of vendors able or willing to provide the necessary equipment, supplies and materials, 
including as a result of commitments of vendors to other customers or third parties.

These price increases, delays in delivery and interruptions in supply may require us to increase capital and repair 

expenditures and incur higher operating costs. Severe shortages, delays in delivery and interruptions in supply could limit our 
ability to construct and operate our drilling rigs or pressure pumping fleets and could have a material adverse effect on our 
business, results of operations, cash flows and financial condition.

Oilfield services equipment, refurbishment and new asset construction projects, as well as the reactivation of oilfield service 
assets that have been idle for six months or longer, are subject to risks which could cause delays or cost overruns and 
adversely affect our business, cash flows, results of operations and financial position.

Oilfield services equipment or assets being upgraded, converted or re-activated following a period of inactivity may 

experience start-up complications and may encounter other operational problems that could result in significant delays, 
uncompensated downtime, reduced dayrates or the cancellation, termination or non-renewal of contracts. In this regard, due to 
market conditions, we have temporarily shut down certain of our service offerings, including contract land drilling, flowback, 
30

 
 
 
 
 
 
 
cementing and acidizing operations. Further, construction and upgrade projects are subject to risks of delay or significant cost 
overruns inherent in any large construction project from numerous factors, including the following:

• 
• 
• 
• 
• 
• 

shortages of equipment, materials or skilled labor;
unscheduled delays in the delivery of ordered materials and equipment or shipyard construction;
failure of equipment to meet quality and/or performance standards;
financial or operating difficulties of equipment vendors;
unanticipated actual or purported change orders;
inability by us or our customers to obtain required permits or approvals, or to meet applicable regulatory 
standards in our areas of operations;
unanticipated cost increases between order and delivery;
• 
adverse weather conditions and other events of force majeure;
• 
• 
design or engineering changes; and
•  work stoppages and other labor disputes.

The occurrence of any of these events could have a material adverse effect on our business, cash flows, results of 

operations and financial position.

Advancements in oilfield service technologies could have a material adverse effect on our business, financial condition, 
results of operations and cash flows.

The oilfield services industry is characterized by rapid and significant technological advancements and introductions 
of new products and services using new technologies. As new horizontal and directional drilling, pressure pumping, pressure 
control and well service technologies develop, we may be placed at a competitive disadvantage, and competitive pressure may 
force us to implement new technologies at a substantial cost. We may not be able to successfully acquire or use new 
technologies. Further, our customers are increasingly demanding the services of newer, higher specification drilling rigs. There 
can be no assurance that we will:

have sufficient capital resources to build new, technologically advanced equipment and other assets;
successfully integrate additional oilfield service equipment and other assets;
effectively manage the growth and increased size of our organization, equipment and other assets;
successfully deploy idle, stacked or additional oilfield service assets;

• 
• 
• 
• 
•  maintain crews necessary to operate additional drilling rigs or pressure pumping service equipment; or
• 

successfully improve our financial condition, results of operations, business or prospects.

If we are not successful in building or acquiring new oilfield service equipment and other assets or upgrading our 

existing rigs and equipment in a timely and cost-effective manner, we could lose market share. New technologies, services or 
standards could render some of our services, equipment and other assets obsolete, which could have a material adverse impact 
on our business, cash flows, results of operations and financial condition.

Our business depends upon our ability to obtain specialized equipment and parts from third-party suppliers, and we may be 
vulnerable to delayed deliveries and future price increases.

We purchase specialized equipment and parts from third party suppliers. At times during the business cycle, there is a 

high demand for hydraulic fracturing, coiled tubing and other oilfield services and extended lead times to obtain equipment 
needed to provide these services. Further, there are a limited number of suppliers that manufacture the equipment we use. 
Should our current suppliers be unable or unwilling to provide the necessary equipment and parts or otherwise fail to deliver 
the products timely and in the quantities required, any resulting delays in the provision of our services could have a material 
adverse effect on our business, financial condition, results of operations and cash flows. In addition, future price increases for 
this type of equipment and parts could negatively impact our ability to purchase new equipment to update or expand our 
existing fleet or to timely repair equipment in our existing fleet.

An increase in the prices of certain materials used in our businesses could adversely affect our business, financial 
condition, results of operation and cash flows.

We are exposed to market risk of increases in certain commodity prices of materials, such as copper and steel, which 

are used as components of supplies or materials utilized in some of our infrastructure and pressure pumping businesses.  An 
increase in these materials could increase our operating costs, limit our ability to service our customers’ needs or otherwise 
materially and adversely affect our business, financial condition, results of operation and cash flows.

31

 
 
 
 
   
Inaccuracies in estimates of volumes and qualities of our sand reserves could result in lower than expected sales and higher 
than expected production costs.

Estimates of our sand reserves are by nature imprecise and depend to some extent on statistical inferences drawn from 
available data, which may prove unreliable. There are numerous uncertainties inherent in estimating quantities and qualities of 
sand reserves and costs to mine recoverable reserves, including many factors beyond our control. Estimates of economically 
recoverable sand reserves necessarily depend on a number of factors and assumptions, all of which may vary considerably from 
actual results, such as:

• 

• 

• 

geological and mining conditions and/or effects from prior mining that may not be fully identified by available 
data or that may differ from experience;
assumptions concerning future prices of frac sand, operating costs, mining technology improvements, 
development costs and reclamation costs; and
assumptions concerning future effects of regulation, including the issuance of required permits and taxes by 
governmental agencies.

Any inaccuracy in the estimates related to our sand reserves could result in lower than expected sales and higher than 

expected costs. For example, these estimates assume that our revenue and cost structure will remain relatively constant over the 
life of our reserves. If these assumptions prove to be inaccurate, some or all of our reserves may not be economically mineable, 
which could have a material adverse effect on our business, financial condition, results of operations and cash flows. In 
addition, our current customer contracts require us to deliver frac sand that meets certain specifications. If the estimates of the 
quality of our sand reserves, including the volumes of the various specifications of those reserves, prove to be inaccurate, we 
may incur significantly higher excavation costs without corresponding increases in revenues, we may not be able to meet our 
contractual obligations, or our facilities may have a shorter than expected reserve life, which could have a material adverse 
effect on our business, financial condition, results of operations and cash flows.

As part of our natural sand proppant services business, we rely on third parties for raw materials and transportation, and 
the suspension or termination of our relationship with one or more of these third parties could adversely affect our business, 
financial conditions, results of operations and cash flows.

As part of our natural sand proppant services business, we mine and process sand into premium monocrystalline sand, 
a specialized mineral that is used as a proppant (also known as frac sand) at our Barron County and Jackson County, Wisconsin 
plants.  We also buy processed sand from suppliers on the spot market. In addition, we also buy raw or washed sand and 
process it at our indoor sand processing plant located in Pierce County, Wisconsin. We sell natural sand proppant to our 
customers for use in their hydraulic fracturing operations to enhance the recovery rates of hydrocarbons from oil and natural 
gas wells. We also provide logistics solutions to deliver our frac sand products to our customers. Because our customers 
generally find it impractical to store frac sand in large quantities near their job sites, they seek to arrange for product to be 
delivered where and as needed, which requires predictable and efficient loading and shipping of product. To facilitate our 
logistics and transload facility capabilities, we contract with third party providers to transport our frac sand products to railroad 
facilities for delivery to our customers. We also lease a railcar fleet from various third parties to deliver our frac sand products 
to our customers and lease or otherwise utilize origin and destination transloading facilities. The suspension, termination or 
nonrenewal of our relationship with any one or more of these third parties involved in the sourcing, transportation and delivery 
of our frac sand products could result in material operational delays, increase our operating costs, limit our ability to service our 
customers’ wells or otherwise materially and adversely affect our business, financial condition, results of operations and cash 
flows.

Future performance of our natural sand proppant services business will depend on our ability to succeed in competitive 
markets, and on our ability to appropriately react to potential fluctuations in the demand for and supply of frac sand.

In our natural sand proppant services business, we operate in a highly competitive market that is characterized by a 

small number of large, national producers and a larger number of small, regional or local producers. Competition in the 
industry is based on price, consistency and quality of product, site location, distribution and logistics capabilities, customer 
service, reliability of supply and breadth of product offering. The large, national producers with whom we compete include 
Badger Mining Corporation, Covia Holdings Corporation, Hi-Crush Partners LP, Preferred Proppants LLC, Smart Sand, Inc., 
Emerge Energy Services LP and U.S. Silica Holdings Inc. Our larger competitors may have greater financial and other 
resources than we do, may develop technology superior to ours, may have production facilities that are located closer to sand 
mines from which raw sand is mined or to their key customers than our facilities or have a more cost effective access to raw 
sand and transportation facilities than we do. Should the demand for hydraulic fracturing services decrease, prices in the frac 

32

 
 
 
 
 
sand market could materially decrease as producers may seek to preserve market share or exit the market and sell frac sand at 
below market prices. In addition, oil and natural gas exploration and production companies and other providers of hydraulic 
fracturing services could acquire their own frac sand reserves, develop or expand frac sand production capacity or otherwise 
fulfill their own proppant requirements and existing or new frac sand producers could add to or expand their frac sand 
production capacity, which may negatively impact pricing and demand for our frac sand. We may not be able to compete 
successfully against either our larger or smaller competitors in the future, and competition could have a material adverse effect 
on our business, financial condition, results of operations and cash flows.

Demand for our frac sand products could be reduced by changes in well stimulation processes and technologies, as well as 
changes in governmental regulations and other applicable law.

As part of our natural sand proppant services business, we mine, process and sell frac sand products to our customers 
for use in their hydraulic fracturing operations to enhance the recovery rates of hydrocarbons from oil and natural gas wells. A 
significant shift in demand from frac sand to other proppants, or the development of new processes to replace hydraulic 
fracturing altogether, could cause a decline in the demand for the frac sand we produce and result in a material adverse effect 
on our business, financial condition, results of operations and cash flows. Further, federal and state governments and agencies 
have adopted various laws and regulations or are evaluating proposed legislation and regulations that are focused on the 
extraction of shale gas or oil using hydraulic fracturing, a process which utilizes proppants such as those that we produce. 
Future hydraulic fracturing-related legislation or regulations could restrict the ability of our customers to utilize, or increase the 
cost associated with, hydraulic fracturing, which could reduce demand for our proppants and adversely affect our business, 
financial condition, results of operations and cash flows. For additional information regarding the regulation of hydraulic 
fracturing, see “—Risks Related to Our Business and the Oil and Natural Gas Industry—Federal and state legislative and 
regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional operating restrictions or 
delays.”

An increase in the supply of raw frac sand having similar characteristics as the raw frac sand we produce and sell could 
make it more difficult for us to market our sand on favorable terms or at all.

From time to time we have entered into take-or-pay contracts with our principal raw frac sand supplier for our Pierce 
County, Wisconsin plant. If significant new reserves of raw frac sand continue to be discovered and developed, and those frac 
sands have similar characteristics to the frac sand we produce and sell, the market price for our frac sand may decline. If the 
market price for our frac sand falls below an amount equal to the contracted purchase price in our take-or-pay contract plus our 
processing and related transportation costs, this could have an adverse effect on our business, financial condition, results of 
operations and cash flows over the remaining term of this contract.

We face distribution and logistics challenges in our business.

In response to various factors, including fluctuations in oil and natural gas prices, our customers may shift their focus 

among resource plays, some of which can be located in geographic areas that do not have well-developed transportation and 
distribution infrastructure systems. Some geographic areas, including the areas in which our sand facilities are located, have 
limited access to railroads. Any interruption or delay in the railroad access or service may affect our ability to ship and/or the 
timing of shipment of our frac sand to our customers, which may adversely affect our revenues or result in increased costs, and 
thus could negatively impact our results of operations and financial condition. Serving our customers in these less-developed 
areas presents distribution and other operational challenges that may affect our sales and could negatively impact our operating 
costs. Labor disputes, system constraints, derailments, adverse weather conditions or other environmental events, an 
increasingly tight railcar leasing market and changes to rail freight systems, among other factors, could interrupt or limit 
available transportation services, could affect our ability to timely and cost-effectively deliver our frac sand to our customers 
and could provide a competitive advantage to our competitors located in closer proximity to our customers. Failure to find 
long-term solutions to these logistics challenges could adversely affect our business, financial condition, results of operations 
and cash flows.

Increasing transportation and related costs could have a material adverse effect on our business.

Because of the relatively low cost of producing frac sand, transportation expenses and related costs, including freight 

charges, fuel surcharges, transloading fees, switching fees, railcar lease costs, demurrage costs and storage fees, comprise a 
significant component of the total delivered cost of frac sand sales. The relatively high transportation expenses and related costs 
tend to favor frac sand producers located in close proximity to their customers. As we expand our frac sand production, our 
need for additional transportation services and transload network access increases. We contract with truck and rail services to 
move frac sand from our production facilities to transload sites and our customers, and increased costs under these contracts 

33

 
 
 
 
could adversely affect our results of operations. In addition, we bear the risk of non-delivery under our contracts. A significant 
increase in transportation service rates, a reduction in the dependability or availability of transportation or transload services, or 
relocation of our customers’ businesses to areas farther from our plants or transloading facilities could impair our ability to 
deliver our products economically to our customers and our ability to expand into different markets.

Diminished access to water and inability to secure or maintain necessary permits may adversely affect operations of our frac 
sand processing plants.

The processing of raw sand and production of natural sand proppant require significant amounts of water. As a result, 

securing water rights and water access is necessary to operate our processing facilities. If the areas where our facilities are 
located experience water shortages, restrictions or any other constraints due to drought, contamination or otherwise, there may 
be additional costs associated with securing water access. Although we have obtained water rights to service our activities when 
we are operating our processing plants, the amount of water that we are entitled to use pursuant to our water rights must be 
determined by the appropriate regulatory authorities. Such regulatory authorities may amend the regulations regarding such 
water rights, increase the cost of maintaining such water rights or eliminate our current water rights, and we may be unable to 
retain all or a portion of such water rights. If implemented, these new regulations could also affect local municipalities and 
other industrial operations and could have a material adverse effect on costs involved in operating our processing plant. Such 
changes in laws, regulations or government policy and related interpretations pertaining to water rights may alter the 
environment in which we do business, which may have an adverse effect on our business, financial condition, results of 
operations and cash flows. Additionally, a water discharge permit may be required to properly dispose of water at our 
processing sites when in operation. Certain of our facilities are also required to obtain storm water permits. The water 
discharge, storm water or any other permits we may be required to have in order to conduct our frac sand processing operations 
is subject to regulatory discretion, and any inability to obtain or maintain the necessary permits could have an adverse effect on 
our ability to run such operations.

Similar to our natural sand proppant services, certain of our completion and production services, particularly our hydraulic 
fracturing services, are substantially dependent on the availability of water. Restrictions on our ability, or our customers’ 
ability, to obtain water may have an adverse effect on our business, financial condition, results of operations and cash flows.

Water is an essential component of deep shale oil and natural gas production during both the drilling and hydraulic 

fracturing processes. In recent years, certain areas in which we operate have experienced drought conditions and competition 
for water in such areas is growing. As a result, some local water districts have begun restricting the use of water subject to their 
jurisdiction for hydraulic fracturing to protect local water supply. Our inability, or customers’ inability, to obtain water to use in 
our operations from local sources or to effectively utilize flowback water could have an adverse effect on our business, 
financial condition, results of operations and cash flows.

The customized nature, and remote location, of the modular camps that we provide and service present unique challenges 
that could adversely affect our ability to successfully operate our remote accommodations business.

We rely on a third-party subcontractor to manufacture and install the customized modular units used in our remote 

accommodations business. These customized units often take a considerable amount of time to manufacture and, once 
manufactured, often need to be delivered to remote areas that are frequently difficult to access by traditional means of 
transportation. In the event we are unable to provide these modular units in a timely fashion, we may not be entitled to full, or 
any, payment therefor under the terms of our contracts with customers. In addition, the remote location of the modular camps 
often makes it difficult to install and maintain the units, and our failure, on a timely basis, to have such units installed and 
provide maintenance services could result in our breach of, and non-payment by our customers under, the terms of our 
customer contracts. Any of these factors could have a material adverse effect on our remote accommodation business and our 
overall financial condition and results of operations.

34

 
 
 
Health and food safety issues and food-borne illness concerns could adversely affect our remote accommodations business.

We provide food services to our customers as part of our remote accommodations business and, as a result, face health 
and food safety issues that are common in the food and hospitality industries. Food-borne illnesses, such as E. coli, hepatitis A, 
trichinosis or salmonella, and food safety issues have occurred in the food industry in the past and could occur in the future. 
Our reliance on third-party food suppliers and distributors increases the risk that food-borne illness incidents could be caused 
by factors outside of our control. New illnesses resistant to any precautions may develop in the future, or diseases with long 
incubation periods could arise. Further, the remote nature of our accommodation facilities and related food services may 
increase the risk of contamination of our food supply and create additional health and hygiene concerns due to the limited 
access to modern amenities and conveniences that may not be faced by other food service providers or hospitality businesses 
operating in an urban environment. If our customers become ill from food-borne illness, we could be forced to close some or all 
of our remote accommodation facilities on a temporary basis or otherwise. Any such incidents and/or any report of publicity 
linking us to incidents of food-borne illness or other food safety issues, including food tampering or contamination, could 
adversely affect our remote accommodations business as well as our overall financial condition and results of operations.

Development of permanent infrastructure in the Canadian oil sands region or other locations where we locate our remote 
accommodations could negatively impact our remote accommodations business.

Our remote accommodations business specializes in providing modular housing and related services for work forces in 

remote areas which lack the infrastructure typically available in towns and cities. If permanent towns, cities and municipal 
infrastructure develop in the oil sands region of northern Alberta, Canada or other regions where we locate our modular camps, 
then demand for our accommodations could decrease as customer employees move to the region and choose to utilize 
permanent housing and food services.

Revenue generated and expenses incurred by our remote accommodation business are denominated in the Canadian dollar 
and could be negatively impacted by currency fluctuations.

Our remote accommodation business 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 combined results of operations or financial position. We also maintain cash balances denominated in the 
Canadian dollar. At December 31, 2019, we had $4 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 a decrease in pre-tax income of 
approximately $0.04 million as of December 31, 2019. Conversely, a corresponding decrease in the strength of the Canadian 
dollar would have resulted in a comparable increase 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.

Our business is difficult to evaluate because we have a limited operating history.

Mammoth Energy Services, Inc. was formed in June 2016, and did not conduct any material business operations prior 

to its initial public offering, or the IPO, which closed on October 19, 2016. Many of our subsidiaries were formed, and their 
services and operations commenced, after the IPO. Prior to the IPO, Mammoth Energy Services, Inc. was a wholly-owned 
subsidiary of Mammoth Energy Partners LP, referred to as Mammoth Partners, which was originally formed in February 2014. 
Except as expressly noted otherwise, the historical financial information of Mammoth Energy Services, Inc. and operational 
data for the periods prior to October 12, 2016 is that of Mammoth Partners and its consolidated subsidiaries. These subsidiaries 
were formed or acquired between 2007 and 2016. As a result, there is only limited historical financial and operating 
information available upon which to base your evaluation of our performance.

In the course of our business, we may become subject to lawsuits, indemnity or other claims, which could materially and 
adversely affect our business, results of operations and cash flows.

In addition to the investigations and legal proceedings referenced in the risk factors above, from time to time, we are 
subject to various claims, lawsuits and other legal proceedings brought or threatened against us in the course of our business. 
These actions and proceedings may seek, among other things, compensation for alleged personal injury, workers’ 
compensation, employment discrimination and other employment-related damages, breach of contract, indemnity claims, 
property damage and violation of federal or state securities laws. We may also be subject to litigation in the normal course of 
business involving allegations of violations of the Fair Labor Standards Act and state wage and hour laws.

Claimants may seek large damage awards and defending claims can involve significant costs. When appropriate, we 
establish accruals for litigation and contingencies that we believe to be adequate in light of current information, legal advice 

35

 
 
 
 
 
 
and our indemnity insurance coverages. We reassess our potential liability for litigation and contingencies as additional 
information becomes available and adjust our accruals as necessary. We could experience a reduction in our profitability and 
liquidity if we do not properly estimate the amount of required accruals for litigation or contingencies, or if our insurance 
coverage proves to be inadequate or becomes unavailable, or if our self-insurance liabilities are higher than expected. The 
outcome of litigation is difficult to assess or quantify, as plaintiffs may seek recovery of very large or indeterminate amounts 
and the magnitude of the potential loss may remain unknown for substantial periods of time. Furthermore, because litigation is 
inherently uncertain, the ultimate resolution of any such claim, lawsuit or proceeding through settlement, mediation, or court 
judgment could have a material adverse effect on our business, financial condition or results of operations. In addition, claims, 
lawsuits and proceedings may harm our reputation or divert management’s attention from our business or divert resources away 
from operating our business, and cause us to incur significant expenses, any of which could have a material adverse effect on 
our business, financial condition, results of operations and cash flows. Please see Note 20. Commitments and Contingencies to 
our consolidated financial statements elsewhere in this annual report. 

We rely on a few key employees whose absence or loss could adversely affect our business.

Many key responsibilities within our business have been assigned to a small number of employees. The loss of their 

services could adversely affect our business. In particular, the loss of the services of our Chief Executive Officer or Chief 
Financial Officer could disrupt our operations. We do not have any written employment agreement with our executives at this 
time. Further, we do not maintain “key person” life insurance policies on any of our employees. As a result, we are not insured 
against any losses resulting from the death of our key employees.

If we are unable to employ a sufficient number of skilled and qualified workers, our capacity and profitability could be 
diminished and our growth potential could be impaired.

The delivery of our products and services requires skilled and qualified workers with specialized skills and experience 

who can perform physically demanding work. As a result of the volatility of the energy services industry and the demanding 
nature of the work, workers may choose to pursue employment in fields that offer a more desirable work environment at wage 
rates that are competitive. Our ability to be productive and profitable will depend upon our ability to employ and retain skilled 
workers. In addition, our ability to expand our operations depends in part on our ability to increase the size of our skilled labor 
force. The demand for skilled workers is high, and the supply is limited. As a result, competition for experienced energy service 
personnel is intense, and we face significant challenges in competing for crews and management with large and well 
established competitors. A significant increase in the wages paid by competing employers could result in a reduction of our 
skilled labor force, increases in the wage rates that we must pay, or both. If either of these events were to occur, our capacity 
and profitability could be diminished and our growth potential could be impaired.

Unionization efforts could increase our costs or limit our flexibility.

Presently, none of our employees work under collective bargaining agreements. Unionization efforts have been made 
from time to time within our industries, to varying degrees of success. Any such unionization could increase our costs or limit 
our flexibility.

Our operations may be limited or disrupted in certain parts of the continental U.S. and Canada during severe weather 
conditions, which could have a material adverse effect on our financial condition and results of operations.

We provide pressure pumping services, well services and drilling services in the Utica, SCOOP, STACK, Permian 
Basin, Marcellus, Granite Wash, Cana Woodford and Eagle Ford resource plays located in the continental U.S. We provide 
infrastructure services in the northeast, southwest and midwest portions of the United States. We provide remote 
accommodation services in the oil sands in Alberta, Canada. We serve these markets through our facilities and service centers 
located in Ohio, Oklahoma, Texas, Wisconsin, Minnesota, Kentucky, California, Florida and Alberta, Canada. For the years 
ended December 31, 2019 and 2018, we generated approximately 43% and 17%, respectively, of our revenue from our 
operations in Ohio, Wisconsin, Minnesota, North Dakota, Pennsylvania, West Virginia and Canada where weather conditions 
may be severe, particularly during winter and spring months. Repercussions of severe weather conditions may include:

curtailment of services;

• 
•  weather-related damage to equipment resulting in suspension of operations;
•  weather-related damage to our facilities;
• 
• 

inability to deliver equipment and materials to jobsites in accordance with contract schedules; and
loss of productivity.

36

 
 
 
 
Many municipalities, including those in Ohio and Wisconsin, impose bans or other restrictions on the use of roads and 
highways, which include weight restrictions on the paved roads that lead to our jobsites due to the muddy conditions caused by 
spring thaws. This can limit our access to these jobsites and our ability to service wells in these areas. These constraints and the 
resulting shortages or high costs could delay our operations and materially increase our operating and capital costs in those 
regions. Weather conditions may also affect the price of crude oil and natural gas, and related demand for our services. Any of 
these factors could have a material adverse effect on our financial condition and results of operations.

Concerns over general economic, business or industry conditions may have a material adverse effect on our results of 
operations, liquidity and financial condition.

Concerns over global economic conditions, energy costs, geopolitical issues, inflation, the availability and cost of 

credit, the European, Asian and the United States financial markets and global or national health concerns have contributed to 
economic uncertainty and diminished expectations for the global economy. These factors, combined with volatility in 
commodity prices, business and consumer confidence and unemployment rates, have in the past precipitated and may in the 
future precipitate an economic slowdown. Concerns about global economic growth may have a significant adverse impact on 
global financial markets and commodity prices. If the economic climate in the United States or abroad deteriorates, worldwide 
demand for petroleum products could diminish, which could impact the price at which oil, natural gas and natural gas liquids 
can be sold, which could affect the ability of our customers to continue operations and ultimately adversely impact our results 
of operations, liquidity and financial condition.

A terrorist attack or armed conflict could harm our business.

The occurrence or threat of terrorist attacks in the United States or other countries, anti-terrorist efforts and other 

armed conflicts involving the United States or other countries, including continued hostilities in the Middle East, may adversely 
affect the United States and global economies and could prevent us from meeting our financial and other obligations. If any of 
these events occur, the resulting political instability and societal disruption could reduce overall demand for oil and natural gas, 
potentially putting downward pressure on demand for our services and causing a reduction in our revenues. Oil and natural gas 
related facilities could be direct targets of terrorist attacks, and our operations could be adversely impacted if infrastructure 
integral to our customers’ operations is destroyed or damaged. Costs for insurance and other security may increase as a result of 
these threats, and some insurance coverage may become more difficult to obtain, if available at all.

Our operations require substantial capital and we may be unable to obtain needed capital or financing on satisfactory terms 
or at all, which could limit our ability to grow.

Our capital budget for 2020 is estimated to be up to $20 million depending upon industry conditions and our financial 

results. Since November 2014, we have funded our capital expenditures primarily with cash proceeds from our initial public 
offering, cash generated by operations, borrowings under our revolving credit facility and, in the case of our acquisitions in 
June 2017, the issuance of shares of our common stock. We may be unable to generate sufficient cash from operations and 
other capital resources to meet our operating needs and/or maintain planned or future levels of capital expenditures which, 
among other things, may prevent us from acquiring new equipment or properly maintaining our existing equipment. As of 
February 26, 2020, we had approximately $21 million of available borrowing capacity under our revolving credit facility. See 
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital 
Resources—Our Revolving Credit Facility. Further, any disruptions or continuing volatility in the global financial markets may 
lead to an increase in interest rates or a contraction in credit availability impacting our ability to finance our operations. This 
could put us at a competitive disadvantage, impair our ability to meet our operating needs or interfere with our growth plans. 
Further, our actual capital expenditures for 2020 or future years could exceed our capital expenditure budget. In the event our 
operating or capital expenditure requirements at any time are greater than the amount we have available, we could be required 
to seek additional sources of capital, which may include debt financing, joint venture partnerships, sales of assets, sale-
leaseback transactions, offerings of debt or equity securities or other means. We may not be able to obtain any such alternative 
source of capital. We may be required to curtail or eliminate contemplated activities. If we can obtain alternative sources of 
capital, the terms of such alternative may not be favorable to us. In particular, the terms of any debt financing may include 
covenants that significantly restrict our operations. Our inability to grow as planned may reduce our chances of achieving, 
maintaining and improving profitability.

The growth of our business through acquisitions may expose us to various risks, including those relating to difficulties in 
identifying suitable, accretive acquisition opportunities and integrating businesses, assets and personnel, as well as 
difficulties in obtaining financing for targeted acquisitions and the potential for increased leverage or debt service 
requirements.

37

 
 
 
 
 
As a component of our business strategy, we have pursued and intend to continue to pursue selected, accretive 

acquisitions of complementary assets, businesses and technologies. Acquisitions involve numerous risks, including:

• 

• 
• 

• 
• 
• 
• 

unanticipated costs and assumption of liabilities and exposure to unforeseen liabilities of acquired businesses, 
including but not limited to environmental liabilities;
difficulties in integrating the operations and assets of the acquired business and the acquired personnel;
limitations on our ability to properly assess and maintain an effective internal control environment over an 
acquired business, in order to comply with public reporting requirements;
potential losses of key employees and customers of the acquired businesses;
inability to commercially develop acquired technologies;
risks of entering markets in which we have limited prior experience; and
increases in our expenses and working capital requirements.

The process of integrating an acquired business may involve unforeseen costs and delays or other operational, 
technical and financial difficulties and may require a disproportionate amount of management attention and financial and other 
resources. Our failure to achieve consolidation savings, to incorporate the acquired businesses and assets into our existing 
operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on our 
financial condition and results of operations. Furthermore, there is intense competition for acquisition opportunities in our 
industries. Competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions. In 
addition, we may not have sufficient capital resources to complete additional acquisitions. Historically, we have financed 
capital expenditures primarily with funding from our initial public offering, cash generated by operations, borrowings under our 
revolving credit facility and funding from our equity investors. We may incur substantial indebtedness to finance future 
acquisitions and also may issue equity, debt or convertible securities in connection with such acquisitions. Debt service 
requirements could represent a significant burden on our results of operations and financial condition and the issuance of 
additional equity or convertible securities could be dilutive to our existing stockholders. Furthermore, we may not be able to 
obtain additional financing on satisfactory terms. Even if we have access to the necessary capital, we may be unable to continue 
to identify additional suitable acquisition opportunities, negotiate acceptable terms or successfully acquire identified targets. 
Our ability to grow through acquisitions and manage growth will require us to continue to invest in operational, financial and 
management information systems and to attract, retain, motivate and effectively manage our employees. The inability to 
effectively manage the integration of acquisitions could reduce our focus on subsequent acquisitions and current operations, 
which, in turn, could negatively impact our earnings and growth. Our financial position and results of operations may fluctuate 
significantly from period to period, based on whether or not significant acquisitions are completed in particular periods.

We may have difficulty managing growth in our business, which could adversely affect our financial condition and results 
of operations.

As a recently formed company, growth in accordance with our business plan, if achieved, could place a significant 

strain on our financial, technical, operational and management resources. As we expand the scope of our activities, lines of our 
businesses and our geographic coverage through both organic growth and acquisitions, there will be additional demands on our 
financial, technical, operational and management resources. The failure to continue to upgrade our technical, administrative, 
operating and financial control systems or the occurrences of unexpected expansion difficulties, including the failure to recruit 
and retain experienced managers, engineers and other professionals in the energy services industry, could have a material 
adverse effect on our business, financial condition, results of operations and our ability to successfully or timely execute our 
business plan.

If our intended expansion of our business is not successful, our financial condition, profitability and results of operations 
could be adversely affected, and we may not achieve increases in revenue and profitability that we hope to realize.

A key element of our business strategy involves the expansion of our services, geographic presence and customer 

base. These aspects of our strategy are subject to numerous risks and uncertainties, including:

• 
• 
• 

• 
• 

• 

an inability to retain or hire experienced crews and other personnel;
a lack of customer demand for the services we intend to provide;
an inability to secure necessary equipment, raw materials (particularly sand and other proppants) or technology to 
successfully execute our expansion plans;
shortages of water used in our sand processing operations and our hydraulic fracturing operations;
unanticipated delays that could limit or defer the provision of services by us and jeopardize our relationships with 
existing customers and adversely affect our ability to obtain new customers for such services; and
competition from new and existing services providers.

38

 
  
 
 
 
Encountering any of these or any unforeseen problems in implementing our planned expansion could have a material 
adverse impact on our business, financial condition, results of operations and cash flows, and could prevent us from achieving 
the increases in revenues and profitability that we hope to realize.

Our liquidity needs could restrict our operations and make us more vulnerable to adverse economic conditions.

Our indebtedness may adversely affect our operations and limit our growth, and we may have difficulty making debt 

service payments on such indebtedness as payments become due. Our level of indebtedness may affect our operations in 
several ways, including the following:

• 
• 

• 

• 

• 

• 

increasing our vulnerability to general adverse economic and industry conditions;
the covenants that are contained in the agreements governing our indebtedness could limit our ability to borrow 
funds, dispose of assets, pay dividends and make certain investments;
our debt covenants could also affect our flexibility in planning for, and reacting to, changes in the economy and in 
our industries;
any failure to comply with the financial or other covenants of our debt, including covenants that impose 
requirements to maintain certain financial ratios, could result in an event of default, which could result in some or 
all of our indebtedness becoming immediately due and payable;
our level of debt could impair our ability to obtain additional financing in the future for working capital, capital 
expenditures, acquisitions or other general corporate purposes; and
our business may not generate sufficient cash flow from operations to enable us to meet our obligations under our 
indebtedness.

Our revolving credit facility provides, and any future credit facilities may provide, for fluctuating interest rates, which may 
increase or decrease our interest expense.

Our revolving credit facility provides for fluctuating interest rates, primarily based on the London interbank offered 
rate, or LIBOR, for deposits of U.S. dollars. LIBOR tends to fluctuate based on multiple facts, including general short-term 
interest rates, rates set by the U.S. Federal Reserve and other central banks, the supply of and demand for credit in the London 
interbank market and general economic conditions. At December 31, 2019, we had $80 million borrowings outstanding under 
our revolving credit facility and availability under our credit facility was approximately $96 million, after giving effect to $9 
million of outstanding letters of credit. A 1% increase or decrease in the interest rate at that time would have increased or 
decreased our interest expense by approximately $0.8 million per year, based on $80 million outstanding and a weighted 
average interest rate of 4.05%. We have not hedged our interest rate exposure with respect to our floating rate debt. 
Accordingly, our interest expense for any particular period will fluctuate based on LIBOR and other variable interest rates. To 
the extent the interest rates applicable to our floating rate debt increase, our interest expense will increase, in which event we 
may have difficulties making interest payments and funding our other fixed costs, and our available cash flow may be adversely 
affected. 

On July 27, 2017, the U.K. Financial Conduct Authority (the authority that regulates LIBOR) announced that it 
intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. It is unclear whether new methods of 
calculating LIBOR will be established such that it continues to exist after 2021. The U.S. Federal Reserve, in conjunction with 
the Alternative Reference Rates Committee, is considering replacing U.S. dollar LIBOR with a newly created index. It is not 
possible to predict the effect of these changes, other reforms or the establishment of alternative reference rates in the United 
States or elsewhere.

We may not be able to provide services that meet the specific needs of oil and natural gas exploration and production 
companies or utilities at competitive prices.

The markets in which we operate are generally highly competitive and have relatively few barriers to entry. The 

principal competitive factors in our markets are price, product and service quality and availability, responsiveness, experience, 
technology, equipment quality and reputation for safety. We compete with large national and multi-national companies that 
have longer operating histories, greater financial, technical and other resources and greater name recognition than we do. 
Several of our competitors provide a broader array of services and have a stronger presence in more geographic markets. In 
addition, we compete with several smaller companies capable of competing effectively on a regional or local basis. Our 
competitors may be able to respond more quickly to new or emerging technologies and services and changes in customer 
requirements. Some contracts are awarded on a bid basis, which further increases competition based on price. Pricing is often 
the primary factor in determining which qualified contractor is awarded a job. The competitive environment may be further 

39

 
 
 
 
 
 
 
intensified by mergers and acquisitions among oil and natural gas or utility companies or other events that have the effect of 
reducing the number of available customers. As a result of competition, we may lose market share or be unable to maintain or 
increase prices for our present services or to acquire additional business opportunities, which could have a material adverse 
effect on our business, financial condition, results of operations and cash flows.

In addition, some exploration and production companies have begun performing hydraulic fracturing and directional 

drilling on their wells using their own equipment and personnel. Any increase in the development and utilization of in-
house fracturing and directional drilling capabilities by our customers could decrease the demand for our oil and natural gas 
services and have a material adverse impact on our business.

Our operations are subject to hazards inherent in the oil and natural gas and energy infrastructure industries, which could 
expose us to substantial liability and cause us to lose customers and substantial revenue.

Our operations include hazards inherent in the oil and natural gas and energy infrastructure industries, such as 
equipment defects, vehicle accidents, fires, explosions, blowouts, surface cratering, uncontrollable flows of gas or well fluids, 
pipe or pipeline failures, abnormally pressured formations and various environmental hazards such as oil spills and releases of, 
and exposure to, hazardous substances. For example, our operations are subject to risks associated with hydraulic fracturing, 
including any mishandling, surface spillage or potential underground migration of fracturing fluids, including chemical 
additives. The occurrence of any of these events could result in substantial losses to us due to injury or loss of life, severe 
damage to or destruction of property, natural resources and equipment, pollution or other environmental damage, clean-
up responsibilities, regulatory investigations and penalties, suspension of operations and repairs required to resume operations. 
The cost of managing such risks may be significant. The frequency and severity of such incidents will affect operating costs, 
insurability and relationships with customers, employees and regulators. In particular, our customers may elect not to purchase 
our services if they view our environmental or safety record as unacceptable, which could cause us to lose customers and 
substantial revenues. In addition, these risks may be greater for us than some of our competitors because we sometimes acquire 
companies that may not have allocated significant resources and management focus to safety and environmental matters and 
may have a poor environmental and safety record and associated possible exposure. Our insurance may not be adequate to 
cover all losses or liabilities we may suffer. Also, insurance may no longer be available to us or, if it is, its availability may be at 
premium levels that do not justify its purchase. The occurrence of a significant uninsured claim, a claim in excess of the 
insurance coverage limits maintained by us or a claim at a time when we are not able to obtain liability insurance could have a 
material adverse effect on our ability to conduct normal business operations and on our financial condition, results of 
operations and cash flows. In addition, we may not be able to secure additional insurance or bonding that might be required by 
new governmental regulations. This may cause us to restrict our operations, which might severely impact our financial position.

Since hydraulic fracturing activities are part of our operations, they are covered by our insurance against claims made 

for bodily injury, property damage and clean-up costs stemming from a sudden and accidental pollution event. However, we 
may not have coverage if we are unaware of the pollution event and unable to report the “occurrence” to our insurance 
company within the time frame required under our insurance policy. We have no coverage for gradual, long-term pollution 
events. In addition, these policies do not provide coverage for all liabilities, and the insurance coverage may not be adequate to 
cover claims that may arise, or we may not be able to maintain adequate insurance at rates we consider reasonable. A loss not 
fully covered by insurance could have a material adverse effect on our financial position, results of operations and cash flows.

We are subject to extensive environmental, health and safety laws and regulations that may subject us to substantial liability 
or require us to take actions that will adversely affect our results of operations.

Our business is significantly affected by stringent and complex federal, state and local laws and regulations governing 

the discharge of substances into the environment or otherwise relating to environmental protection and health and safety 
matters. As part of our business, we handle, transport and dispose of a variety of fluids and substances, including hydraulic 
fracturing fluids which can contain hydrochloric acid and certain petrochemicals. This activity poses some risks of 
environmental liability, including leakage of hazardous substances from the wells to surface and subsurface soils, surface water 
or groundwater. We also handle, transport and store these substances. The handling, transportation, storage and disposal of 
these fluids are regulated by a number of laws, including: the Resource Conservation and Recovery Act; the Comprehensive 
Environmental Response, Compensation, and Liability Act; the Clean Water Act; the Safe Drinking Water Act; and other 
federal and state laws and regulations promulgated thereunder. The cost of compliance with these laws can be significant. 
Failure to properly handle, transport or dispose of these materials or otherwise conduct our operations in accordance with these 
and other environmental laws could expose us to substantial liability for administrative, civil and criminal penalties, cleanup 
and site restoration costs and liability associated with releases of such materials, damages to natural resources and other 
damages, as well as potentially impair our ability to conduct our operations. We could be exposed to liability for cleanup costs, 
natural resource damages and other damages under these and other environmental laws. Such liability is commonly on a strict, 
40

 
 
 
 
joint and several liability basis, without regard to fault. Liability may be imposed as a result of our conduct that was lawful at 
the time it occurred or the conduct of, or conditions caused by, prior operators or other third parties. Environmental laws and 
regulations have changed in the past, and they are likely to change in the future. If existing environmental requirements or 
enforcement policies change and become more stringent, we may be required to make significant unanticipated capital and 
operating expenditures.

Regulation of greenhouse gas emissions could result in increased operating costs and reduced demand for oil and natural 
gas.

In recent years, federal, state and local governments have taken steps to reduce emissions of greenhouse gases, or 

GHGs. The Environmental Protection Agency, or the EPA, has finalized a series of GHG monitoring, reporting and emissions 
control rules for the oil and natural gas industry, and the U.S. Congress has, from time to time, considered adopting legislation 
to reduce emissions. Almost one-half of the states have already taken measures to reduce emissions of GHGs primarily through 
the development of GHG emission inventories and/or regional GHG cap-and-trade programs. While we are subject to certain 
federal GHG monitoring and reporting requirements, our operations currently are not adversely impacted by existing federal, 
state and local climate change initiatives. For a description of existing and proposed GHG rules and regulations, see “—
Regulation of Hydraulic Fracturing.”

At the international level, in December 2015, the United States participated in the 21st Conference of the 

Parties (COP-21) of the United Nations Framework Convention on Climate Change in Paris, France. The resulting Paris 
Agreement calls for the parties to undertake “ambitious efforts” to limit the average global temperature, and to conserve and 
enhance sinks and reservoirs of GHGs. The Agreement went into effect on November 4, 2016. The Agreement establishes a 
framework for the parties to cooperate and report actions to reduce GHG emissions. However, on June 1, 2017, President 
Trump announced that the United States would withdraw from the Paris Agreement, and begin negotiations to either re-enter or 
negotiate an entirely new agreement with more favorable terms for the United States. The Paris Agreement sets forth a specific 
exit process, whereby a party may not provide notice of its withdrawal until three years from the effective date, with such 
withdrawal taking effect one year from such notice. On November 4, 2019, the Trump Administration submitted its formal 
notification of withdrawal to the United Nations. It is not clear what steps, if any, will be taken to negotiate a new agreement, or 
what terms would be included in such an agreement. In response to the announcement, many state and local leaders have stated 
their intent to intensify efforts to uphold the commitments set forth in the international accord.

Although it is not possible at this time to predict how legislation or new regulations that may be adopted to address 

GHG emissions would impact our business, any such future laws and regulations imposing reporting obligations on, or limiting 
emissions of GHGs from, our equipment and operations could require us to incur costs to reduce emissions of GHGs associated 
with our operations. In addition, substantial limitations on GHG emissions could adversely affect demand for oil and natural 
gas and, consequently, the services we provide.

In addition, there have also been efforts in recent years to influence the investment community, including investment

advisors and certain sovereign wealth, pension and endowment funds promoting divestment of fossil fuel equities and 
pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel reserves. Such environmental activism 
and initiatives aimed at limiting climate change and reducing air pollution could interfere with our business activities, 
operations and ability to access capital. Furthermore, claims have been made against certain energy companies alleging that 
GHG emissions from oil and natural gas operations constitute a public nuisance under federal and/or state common law. As a 
result, private individuals or public entities may seek to enforce environmental laws and regulations against us and could allege 
personal injury, property damage or other liabilities. While our business is not a party to any such litigation, we could be named 
in actions making similar allegations. An unfavorable ruling in any such case could significantly impact our operations and 
could have an adverse impact on our financial condition.

Moreover, climate change may cause more extreme weather conditions such as more intense hurricanes,
thunderstorms, tornadoes and snow or ice storms, as well as rising sea levels and increased volatility in seasonal
temperatures. Extreme weather conditions can interfere with our productivity and increase our costs and damage resulting
from extreme weather may not be fully insured. However, at this time, we are unable to determine the extent to which climate
change may lead to increased storm or weather hazards affecting our operations.

Federal and state legislative and regulatory initiatives relating to hydraulic fracturing could result in increased costs and 
additional operating restrictions or delays.

Our business is dependent on our ability to conduct hydraulic fracturing and horizontal drilling activities. Hydraulic 
fracturing is an important and common practice that is used to stimulate production of hydrocarbons, particularly natural gas, 
41

 
 
 
 
 
 
from tight formations, including shales. The process involves the injection of water, sand and chemicals (also called 
“proppants”) under pressure into formations to fracture the surrounding rock and stimulate production. There has been 
increasing public controversy regarding hydraulic fracturing with regard to the use of fracturing fluids, induced seismic activity, 
impacts on drinking water supplies, use of water and the potential for impacts to surface water, groundwater and the 
environment generally. A number of lawsuits and enforcement actions have been initiated across the country implicating 
hydraulic fracturing practices. The hydraulic fracturing process is typically regulated by state oil and natural gas commissions. 
However, legislation has been proposed in recent sessions of Congress to amend the federal Safe Drinking Water Act, or 
SDWA, to repeal the exemption for hydraulic fracturing from the definition of “underground injection,” to require federal 
permitting and regulatory control of hydraulic fracturing, and to require disclosure of the chemical constituents of the fluids 
used in the fracturing process. Furthermore, several federal agencies have asserted regulatory authority over certain aspects of 
the process. In addition, several states and local jurisdictions in which we operate have adopted or are considering adopting 
regulations that could restrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating 
standards and/or require the disclosure of the composition of hydraulic fracturing fluids. For a more detailed description, see 
“Business—Regulation—Regulation of Hydraulic Fracturing.”

If new laws or regulations are adopted that significantly restrict hydraulic fracturing, such laws could make it more 
difficult or costly for us to perform fracturing to stimulate production from tight formations as well as make it easier for third 
parties opposing the hydraulic fracturing process to initiate legal proceedings based on allegations that specific chemicals used 
in the fracturing process could adversely affect groundwater. In addition, if hydraulic fracturing is further regulated at the 
federal, state or local level, our fracturing activities could become subject to additional permitting and financial assurance 
requirements, more stringent construction specifications, increased monitoring, reporting and recordkeeping obligations and 
also to attendant permitting delays and potential increases in costs, which could reduce the demand for our services. Such 
legislative or regulatory changes could cause us to incur substantial compliance costs, and compliance or the consequences of 
any failure to comply by us could have a material adverse effect on our business, financial condition, results of operations and 
cash flows. At this time, it is not possible to estimate the impact on our business of newly enacted or potential federal, state or 
local laws governing hydraulic fracturing.

Legislation or regulatory initiatives intended to address seismic activity could restrict certain of our customers’ drilling and 
production activities, as well as well as their ability to dispose of produced water gathered from such activities, which could 
have a material adverse effect on our business.

State and federal regulatory agencies have recently focused on a possible connection between hydraulic fracturing 
related activities, particularly the underground injection of wastewater into disposal wells, and the increased occurrence of 
seismic activity, and regulatory agencies at all levels are continuing to study the possible linkage between oil and gas activity 
and induced seismicity. In addition, a number of lawsuits have been filed in some states alleging that disposal well operations 
have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. In 
response to these concerns, regulators in some states are seeking to impose additional requirements, including requirements 
regarding the permitting of produced water disposal wells or otherwise to assess the relationship between seismicity and the use 
of such wells.

Certain of our customers dispose of large volumes of produced water gathered from their drilling and production 

operations by injecting it into wells pursuant to permits issued to them by governmental authorities overseeing such disposal 
activities. While these permits are issued pursuant to existing laws and regulations, these legal requirements are subject to 
change, which could result in the imposition of more stringent operating constraints or new monitoring and reporting 
requirements, owing to, among other things, concerns of the public or governmental authorities regarding such gathering or 
disposal activities. The adoption and implementation of any new laws or regulations that restrict our ability to use hydraulic 
fracturing or dispose of produced water gathered from certain of our customers’ drilling and production activities by owned 
disposal wells, could have a material adverse effect on our business, financial condition and results of operations.

Our operations in our natural sand proppant services business are dependent on our rights and ability to mine our 
properties and on our having renewed or received the required permits and approvals from governmental authorities and 
other third parties.

We hold numerous governmental, environmental, mining and other permits, water rights and approvals authorizing 

operations at our production facilities. For our extraction and processing in Wisconsin, the permitting process is subject to 
federal, state and local authority. For example, at the federal level, a Mine Identification Request must be filed and obtained 
before mining commences. If wetlands are implicated, a U.S. Army Corps of Engineers Wetland Permit is required. At the state 
level, a series of permits are required related to air quality, wetlands, water quality (waste water and storm water), grading, 
endangered species and archaeological assessments in addition to other permits depending upon site specific factors and 

42

 
 
operational detail. At the local level, zoning, building, storm water, erosion control, wellhead protection, road usage and access 
are all regulated and require permitting to some degree. A non-metallic mining reclamation permit is required. A decision by a 
governmental agency or other third party to deny or delay issuing a new or renewed permit or approval, or to revoke or 
substantially modify an existing permit or approval, could have a material adverse effect on our ability to continue operations.

Title to, and the area of, mineral properties and water rights may also be disputed. Mineral properties sometimes 

contain claims or transfer histories that examiners cannot verify. A successful claim that we do not have title to our property or 
lack appropriate water rights could cause us to lose any rights to explore, develop and extract minerals, without compensation 
for our prior expenditures relating to such property. Our business may suffer a material adverse effect in the event we have title 
deficiencies.

In some instances, we have received access rights or easements from third parties, which allow for a more efficient 
operation than would exist without the access or easement. A third party could take action to suspend the access or easement, 
and any such action could be materially adverse to our business, results of operations, cash flows or financial condition.

Penalties, fines or sanctions that may be imposed by the U.S. Mine Safety and Health Administration could have a material 
adverse effect on our proppant production and sales business and our overall financial condition, results of operations and 
cash flows.

The U.S. Mine Safety and Health Administration, or MSHA, has primary regulatory jurisdiction over commercial 

silica operations, including quarries, surface mines, underground mines, and industrial mineral process facilities. In addition, 
MSHA representatives perform at least two annual inspections of our production facilities to ensure employee and general site 
safety. As a result of these and future inspections and alleged violations and potential violations, we and our suppliers could be 
subject to material fines, penalties or sanctions. Any of our production facilities or our suppliers’ mines could be subject to a 
temporary or extended shut down as a result of an alleged MSHA violation. Any such penalties, fines or sanctions could have a 
material adverse effect on our proppant production and sales business and our overall financial condition, results of operations 
and cash flows.

Increasing trucking regulations may increase our costs and negatively impact our results of operations.

In connection with our business operations, including the transportation and relocation of our energy service 

equipment, shipment of frac sand and general freight hauling, we operate trucks and other heavy equipment. As such, we 
operate as a motor carrier in providing certain of our services and therefore are subject to regulation by the United States 
Department of Transportation and by various state agencies. These regulatory authorities exercise broad powers, governing 
activities such as the authorization to engage in motor carrier operations, driver licensing, insurance requirements, financial 
reporting and review of certain mergers, consolidations and acquisitions, and transportation of hazardous materials 
(HAZMAT). Our trucking operations are subject to possible regulatory and legislative changes that may increase our costs. 
Some of these possible changes include increasingly stringent environmental regulations, changes in the hours of service 
regulations which govern the amount of time a driver may drive or work in any specific period, onboard black box recorder 
device requirements or limits on vehicle weight and size. Interstate motor carrier operations are subject to safety requirements 
prescribed by the United States Department of Transportation. To a large degree, intrastate motor carrier operations are subject 
to state safety regulations that mirror federal regulations. Matters such as the weight and dimensions of equipment are also 
subject to federal and state regulations. From time to time, various legislative proposals are introduced, including proposals to 
increase federal, state, or local taxes, including taxes on motor fuels, which may increase our costs or adversely impact the 
recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes applicable to us will be enacted.

Certain motor vehicle operators require registration with the Department of Transportation. This registration requires 
an acceptable operating record. The Department of Transportation periodically conducts compliance reviews and may revoke 
registration privileges based on certain safety performance criteria that could result in a suspension of operations.

Restrictions on drilling activities intended to protect certain species of wildlife may adversely affect our ability to conduct 
mining or drilling activities in some of the areas where we operate.

Oil and natural gas operations in our operating areas can be adversely affected by seasonal or permanent restrictions 
on mining or drilling activities designed to protect various wildlife, which may limit our ability to operate in protected areas. 
Permanent restrictions imposed to protect endangered species could prohibit drilling in certain areas or require the 
implementation of expensive mitigation measures. Additionally, the designation of previously unprotected species as threatened 
or endangered in areas where we operate could result in increased costs arising from species protection measures. Restrictions 
on oil and natural gas operations to protect wildlife could reduce demand for our services.

43

 
 
 
 
 
 
 
Conservation measures and technological advances could reduce demand for oil and natural gas and our services.

Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil and 
natural gas, technological advances in fuel economy and energy generation devices could reduce demand for oil and natural 
gas, resulting in reduced demand for oilfield services. The impact of the changing demand for oil and natural gas services and 
products may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Changes in tax laws and regulations or adverse outcomes resulting from examination of our tax returns may adversely 
affect our business, results of operations, financial condition and cash flow.

On December 22, 2017, the President of the United States signed into law Public Law No. 115-97, a comprehensive 

tax reform bill commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act, that significantly reforms the Internal 
Revenue Code of 1986, as amended, or the Code. Among other changes, the Tax Act (i) permanently reduced the U.S. 
corporate income tax rate, (ii) provided for a transition tax (toll tax) on a one-time “deemed repatriation” of accumulated 
foreign earnings, (iii) repealed the corporate alternative minimum tax, (iv) imposed new limitations on the utilization of net 
operating losses, and (v) provided for more general changes to the taxation of corporations, including changes to the 
deductibility of interest expense, the adoption of a modified territorial tax system, and introducing certain anti-base erosion 
provisions. The Tax Act is complex and far-reaching, and we cannot predict with certainty the resulting impact its enactment 
will have on us. The ultimate impact of the Tax Act may differ from our estimates due to changes in interpretations and 
assumptions made by us as well as additional regulatory guidance that may be issued, and any such changes in our 
interpretations and assumptions could have an adverse effect on our business, results of operations, financial condition and cash 
flow. 

On December 10, 2018, the Governor of Puerto Rico signed into law House Bill 1544 as Act 257-2018, or Act 257, 
which amended the Puerto Rico Internal Revenue Code. Among other changes, Act 257 (i) reduces the corporate income tax 
rate from 39% to 37.5%, (ii) provides that the 51% disallowance with respect to expenses paid or incurred with a related party 
may not apply under certain circumstances and (iii) adds requirements for the deductibility of expenses, including meals and 
entertainment, travel and motor vehicles. We cannot predict with certainty the resulting impact the enactment of Act 257 will 
have on us. The ultimate impact of Act 257 may differ from our estimates due to changes in interpretations and assumptions 
made by us as well as additional regulatory guidance that may be issued, and any such changes in our interpretations and 
assumptions could have an adverse effect on our business, results of operations, financial condition and cash flow.

In addition, we are subject to tax liabilities imposed by multiple jurisdictions, including income taxes, indirect taxes 

(excise/duty, sales/use and value-added taxes), payroll taxes, franchise taxes, withholding taxes and ad valorem taxes. New tax 
laws and regulations and changes in existing tax laws and regulations are continuously being enacted or proposed that could 
result in increased expenditures for tax liabilities in the future, which could have a material adverse effect on our results of 
operations, financial condition and cash flows. Additionally, many of these liabilities are subject to periodic audits by the 
respective taxing authority. Subsequent changes to our tax liabilities as a result of these audits may subject us to interest and 
penalties.

Our income tax returns are subject to review and examination by the applicable tax authorities. We regularly assess the 

likelihood of an adverse outcome resulting from these examinations to determine the adequacy of our provision for income 
taxes. We do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed upon 
challenge by a tax authority. Although we believe our tax provisions are adequate, the final determination of tax audits and any 
related disputes could be materially different from our historical income tax provisions and accruals. The results of audits or 
related disputes could have an adverse effect on our financial statements for the periods for which the applicable final 
determinations are made. 

Our operations are subject to a number of operational risks which may result in unexpected costs or liabilities.

Unexpected costs or liabilities may arise from lawsuits or indemnity claims related to the services we perform or have 

performed in the past. We have in the past been, and may in the future be, named as a defendant in lawsuits, claims and other 
legal proceedings during the ordinary course of our business. These actions may seek, among other things, compensation for 
alleged personal injury, workers’ compensation, employment discrimination, breach of contract, property damage, 
environmental remediation, punitive damages, civil penalties or other losses, consequential damages or injunctive or 
declaratory relief. In addition, pursuant to our service arrangements, we generally indemnify our customers for claims related to 
the services we provide under those service arrangements. In some instances, our services are integral to the operation and 
performance of the electric distribution and transmission infrastructure. As a result, we may become subject to lawsuits or 

44

 
 
 
 
 
claims for any failure of the systems we work on, even if our services are not the cause for such failures. In addition, we may 
incur civil and criminal liabilities to the extent that our services contributed to any personal injury or property damage. The 
outcome of any of these lawsuits, claims or legal proceedings could result in significant costs and diversion of managements’ 
attention to the business.

Losses and liabilities from uninsured or underinsured activities could have a material adverse effect on our financial 
condition and operations.

The operational insurance coverage we maintain for our business may not fully insure us against all risks, either 
because insurance is not available or because of the high premium costs relative to perceived risk. Further, any insurance 
obtained by us may not be adequate to cover any losses or liabilities and this insurance may not continue to be available at all 
or on terms which are acceptable to us. Insurance rates have in the past been subject to wide fluctuation and changes in 
coverage could result in less coverage, increases in cost or higher deductibles and retentions. Liabilities for which we are not 
insured, or which exceed the policy limits of our applicable insurance, could have a material adverse effect on our business 
activities, financial condition and results of operations.

We may be subject to claims for personal injury and property damage, which could materially adversely affect our financial 
condition and results of operations.

We operate with most of our customers under master service agreements, or MSAs. We endeavor to allocate potential 

liabilities and risks between the parties in the MSAs. Generally, under our MSAs, including those relating to our hydraulic 
fracturing services, we assume responsibility for, including control and removal of, pollution or contamination which originates 
above surface and originates from our equipment or services. Our customer assumes responsibility for, including control and 
removal of, all other pollution or contamination which may occur during operations, including that which may result from 
seepage or any other uncontrolled flow of drilling fluids. We may have liability in such cases if we are negligent or commit 
willful acts. Generally, our customers also agree to indemnify us against claims arising from their employees’ personal injury or 
death to the extent that, in the case of our hydraulic fracturing operations, their employees are injured or their properties are 
damaged by such operations, unless resulting from our gross negligence or willful misconduct. Similarly, we generally agree to 
indemnify our customers for liabilities arising from personal injury to or death of any of our employees, unless resulting from 
gross negligence or willful misconduct of the customer. In addition, our customers generally agree to indemnify us for loss or 
destruction of customer-owned property or equipment and in turn, we agree to indemnify our customers for loss or destruction 
of property or equipment we own. Losses due to catastrophic events, such as blowouts, are generally the responsibility of the 
customer. However, despite this general allocation of risk, we might not succeed in enforcing such contractual allocation, might 
incur an unforeseen liability falling outside the scope of such allocation or may be required to enter into an MSA with terms 
that vary from the above allocations of risk. As a result, we may incur substantial losses which could materially and adversely 
affect our financial condition and results of operation.

Loss of our information and computer systems could adversely affect our business.

We are heavily dependent on our information systems and computer based programs, including our well operations 

information and accounting data. If any of such programs or systems were to fail or create erroneous information in our 
hardware or software network infrastructure, whether due to cyberattack or otherwise, possible consequences include our loss 
of communication links and inability to automatically process commercial transactions or engage in similar automated or 
computerized business activities. Any such consequence could have a material adverse effect on our business.

We are subject to cyber security risks. A cyber incident could occur and result in information theft, data corruption, 
operational disruption and/or financial loss.

The energy services industry has become increasingly dependent on digital technologies to conduct certain processing 

activities. For example, we depend on digital technologies to perform many of our services and process and record financial 
and operating data. At the same time, cyber incidents, including deliberate attacks or unintentional events, have increased. The 
U.S. government has issued public warnings that indicate that energy assets might be specific targets of cyber security threats. 
Our technologies, systems and networks, and those of our vendors, suppliers and other business partners, may become the 
target of cyberattacks or information security breaches that could result in the unauthorized release, gathering, monitoring, 
misuse, loss or destruction of proprietary and other information, or other disruption of our business operations. In addition, 
certain cyber incidents, such as surveillance, may remain undetected for an extended period. Our systems and insurance 
coverage for protecting against cyber security risks may not be sufficient. As cyber incidents continue to evolve, we may be 
required to expend additional resources to continue to modify or enhance our protective measures or to investigate and 

45

 
 
 
 
remediate any vulnerability to cyber incidents. Our insurance coverage for cyberattacks may not be sufficient to cover all the 
losses we may experience as a result of such cyberattacks.

Risks Inherent to Our Common Stock

Our two largest stockholders control a significant percentage of our common stock, and their interests may conflict with 
those of our other stockholders.

Wexford, through its affiliate MEH Sub LLC, and Gulfport beneficially own approximately 48.9% and 21.8%, 

respectively, of our outstanding common stock. As a result, each of Wexford and Gulfport can exercise significant influence 
over matters requiring stockholder approval, including the election of directors, changes to our organizational documents and 
significant corporate transactions. Further, individuals who serve as our directors are affiliates of Wexford and one of our 
directors has been designated by Gulfport. This concentration of ownership and relationships with Wexford and Gulfport make 
it unlikely that any other holder or group of holders of our common stock will be able to affect the way we are managed or the 
direction of our business. In addition, we have engaged, and expect to continue to engage, in related party transactions 
involving Wexford and Gulfport, and certain companies they control. The interests of Wexford and Gulfport with respect to 
matters potentially or actually involving or affecting us, such as services provided, future acquisitions, financings and other 
corporate opportunities, and attempts to acquire us, may conflict with the interests of our other stockholders. This concentrated 
ownership will make it impossible for another company to acquire us and for you to receive any related takeover premium for 
your shares unless these stockholders approve the acquisition. We are currently involved in a lawsuit with Gulfport in which 
Gulfport is seeking to terminate our pressure pumping contract with it and receive certain alleged damages. See Note 20. 
Commitments and Contingencies to our consolidated financial statements included elsewhere in this annual report.  

A significant reduction by Wexford of its ownership interests in us could adversely affect us.

We believe that Wexford’s substantial ownership interest in us provides it with an economic incentive to assist us to be 
successful. Wexford is not subject to any obligation to maintain its ownership interest in us and may elect at any time to sell all 
or a substantial portion of or otherwise reduce its ownership interest in us. If Wexford sells all or a substantial portion of its 
ownership interest in us, it may have less incentive to assist in our success and its affiliates that serve as members of our board 
of directors may resign. Such actions could adversely affect our ability to successfully implement our business strategies which 
could adversely affect our cash flows or results of operations.

We have and will continue to incur increased costs and obligations as a result of being a public company. 

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses. 

These include costs associated with our public company reporting requirements and corporate governance requirements, 
including requirements under the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Act of 2010, as well as rules implemented 
by the SEC, The Nasdaq Global Select Market and the Financial Industry Regulatory Authority. These rules and regulations 
have increased our legal and financial compliance costs and made some activities more time-consuming and costly. These rules 
and regulations may also make it more difficult and more expensive for us to obtain director and officer liability insurance and 
we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or 
similar coverage. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of 
directors or as executive officers. We estimate that we incur approximately $2.5 million of incremental costs per year associated 
with being a publicly traded company; however, it is possible that our incremental costs of being a publicly traded company 
will be higher than we currently estimate. As a non-emerging growth company, we have incurred and expect to continue to 
incur significant additional expenses and devote substantial management effort toward ensuring compliance with the enhanced 
requirements applicable to such companies, including Section 404 of the Sarbanes-Oxley Act. See “-Risks Related to Our 
Common Stock-We are subject to certain requirements of Section 404 of the Sarbanes-Oxley Act. If we are unable to continue 
to comply with Section 404 or if the costs related to compliance are significant, our profitability, stock price, results of 
operations and financial condition could be materially adversely affected.”

We are subject to certain requirements of Section 404 of the Sarbanes-Oxley Act. If we are unable to continue comply with 
Section 404 or if the costs related to compliance are significant, our profitability, stock price, results of operations and 
financial condition could be materially adversely affected.

As of December 31, 2018, we ceased to be an “emerging growth company” and are now required to comply with the 
enhanced provisions of Section 404 of the Sarbanes-Oxley Act of 2002 applicable to non-emerging growth companies. Section 
404 requires that we not only document and test our internal control over financial reporting and issue management’s 
assessment of our internal control over financial reporting, as we have done in the past, but also that our independent registered 
46

 
 
 
public accounting firm attest to and report on the internal control assessments made by our management. As we perform the 
required testing of, and our auditors’ audit, our internal control over financial reporting, we or they may identify areas requiring 
improvement, and we may have to design enhanced processes and controls to address issues identified through this review. We 
believe that the out-of-pocket costs, the diversion of management’s attention from running the day-to-day operations and 
operational changes caused by the need to comply with the enhanced requirements of Section 404 of the Sarbanes-Oxley Act 
applicable to non-emerging growth companies could be significant. If the time and costs associated with such compliance 
exceed our current expectations, our results of operations could be adversely affected.

If we fail to comply with the requirements of Section 404 of the Sarbanes-Oxley Act, or if we or our auditors identify 

and report material weaknesses in internal control over financial reporting, the accuracy and timeliness of the filing of our 
annual and quarterly reports may be materially adversely affected and could cause investors to lose confidence in our reported 
financial information, which could have a negative effect on the trading price of our common stock. In addition, a material 
weakness in the effectiveness of our internal control over financial reporting could result in an increased chance of fraud and 
the loss of customers, reduce our ability to obtain financing and require additional expenditures to comply with these 
requirements, each of which could have a material adverse effect on our business, results of operations and financial condition.

The corporate opportunity provisions in our certificate of incorporation could enable Wexford, Gulfport or other affiliates of 
ours to benefit from corporate opportunities that might otherwise be available to us.

Subject to the limitations of applicable law, our certificate of incorporation, among other things:

• 

• 

• 

permits us to enter into transactions with entities in which one or more of our officers or directors are financially or 
otherwise interested;
permits any of our stockholders, officers or directors to conduct business that competes with us and to make 
investments in any kind of property in which we may make investments; and
provides that if any director or officer of one of our affiliates who is also one of our officers or directors becomes 
aware of a potential business opportunity, transaction or other matter (other than one expressly offered to that 
director or officer in writing solely in his or her capacity as our director or officer), that director or officer will have 
no duty to communicate or offer that opportunity to us, and will be permitted to communicate or offer that 
opportunity to such affiliates and that director or officer will not be deemed to have (i) acted in a manner 
inconsistent with his or her fiduciary or other duties to us regarding the opportunity or (ii) acted in bad faith or in a 
manner inconsistent with our best interests.

These provisions create the possibility that a corporate opportunity that would otherwise be available to us may be 

used for the benefit of one of our affiliates.

We have engaged in transactions with our affiliates and expect to do so in the future. The terms of such transactions and the 
resolution of any conflicts that may arise may not always be in our or our common stockholders’ best interests.

We have engaged in transactions and expect to continue to engage in transactions with affiliated companies. As 

described elsewhere in this report, including in the notes to our consolidated financial statements, these transactions include, 
among others, a joint venture, agreements to provide our services and frac sand products to our affiliates and agreements 
pursuant to which our affiliates provide or will provide us with certain services, including administrative and advisory services 
and office space. Each of these entities is either controlled by or affiliated with Wexford or Gulfport, as the case may be, and 
the resolution of any conflicts that may arise in connection with such related party transactions, including pricing, duration or 
other terms of service, may not always be in our or our stockholders’ best interests because Wexford and/or Gulfport may have 
the ability to influence the outcome of these conflicts. For a discussion of potential conflicts, see “—Risks Inherent to Our 
Common Stock—Our two largest stockholders control a significant percentage of our common stock, and their interests may 
conflict with those of our other stockholders.”

Prior to the IPO, there was no public market for our common stock and if the price of our common stock fluctuates 
significantly, your investment could lose value.

Prior to the completion of the IPO in October 2016, there was no public market for our common stock. Although our 

common stock is listed on The Nasdaq Global Select Market, an active public market for our common stock may not be 
maintained. If an active public market for our common stock is not maintained, the trading price and liquidity of our common 
stock will be materially and adversely affected. Without a large float, our common stock is less liquid than the securities of 
companies with broader public ownership and, as a result, the trading prices of our common stock may be more volatile. The 
market price for our common stock has fluctuated significantly, ranging from a high of $24.62 per share to a low of $1.22 per 
47

 
 
 
 
 
 
share during 2019. In addition, in the absence of an active public trading market, investors may be unable to liquidate their 
investment in us. In addition, the stock market is subject to significant price and volume fluctuations, and the price of our 
common stock could fluctuate widely in response to several factors, including:

• 
• 
• 
• 
• 
• 
• 
• 

our quarterly or annual operating results;
changes in our earnings estimates;
investment recommendations by securities analysts following our business or our industries;
additions or departures of key personnel;
changes in the business, earnings estimates or market perceptions of our competitors;
our failure to achieve operating results consistent with securities analysts’ projections;
changes in industry, general market or economic conditions; and
announcements of legislative or regulatory change.

The stock market has experienced extreme price and volume fluctuations in recent years that have significantly 
affected the quoted prices of the securities of many companies, including companies in our industries. The changes often 
appear to occur without regard to specific operating performance. The price of our common stock could fluctuate based upon 
factors that have little or nothing to do with our company and these fluctuations could materially reduce the price for our 
common stock.

Wexford and Gulfport beneficially own a substantial amount of our common stock and may sell such common stock in the 
public or private markets. Sales of these shares of common stock or sales of substantial amounts of our common stock by 
other stockholders, or the perception that such sales may occur, could adversely affect the prevailing market price of our 
common stock.

As of December 31, 2019, Wexford and Gulfport beneficially owned 48.9% and 21.8% shares of our common stock, 

respectively. Sales of these shares of common stock or sales of substantial amounts of our common stock by other stockholders, 
or the perception that such sales may occur, could cause the price of our common stock to decline. In addition, the sale of these 
shares could impair our ability to raise capital through the sale of additional common or preferred stock.

If securities or industry analysts do not publish research or reports about our business, if they adversely revise their 
recommendations regarding our stock or if our operating results do not meet their expectations, the price of our stock could 
decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities 
analysts publish about us or our business. If one or more of these analysts cease coverage of our company or fail to publish 
reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading 
volume to decline. Moreover, if one or more of the analysts who cover our company downgrades our stock or if our operating 
results do not meet their expectations, our stock price could decline.

We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock.

Our certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or 

series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our 
common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more 
classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we 
might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of 
specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation 
preferences we might assign to holders of preferred stock could affect the residual value of the common stock.

Provisions in our certificate of incorporation and bylaws and Delaware law make it more difficult to effect a change in 
control of the company, which could adversely affect the price of our common stock.

The existence of some provisions in our certificate of incorporation and bylaws and Delaware corporate law could 

delay or prevent a change in control of our company, even if that change would be beneficial to our stockholders. Our 
certificate of incorporation and bylaws contain provisions that may make acquiring control of our company difficult, including:

• 

• 

provisions regulating the ability of our stockholders to nominate directors for election or to bring matters for 
action at annual meetings of our stockholders;
limitations on the ability of our stockholders to call a special meeting and act by written consent;

48

 
 
 
 
 
 
• 

• 

• 

• 

the ability of our board of directors to adopt, amend or repeal bylaws, and the requirement that the affirmative 
vote of holders representing at least 66 2/3% of the voting power of all outstanding shares of capital stock be 
obtained for stockholders to amend our bylaws;
the requirement that the affirmative vote of holders representing at least 66 2/3% of the voting power of all 
outstanding shares of capital stock be obtained to remove directors;
the requirement that the affirmative vote of holders representing at least 66 2/3% of the voting power of all 
outstanding shares of capital stock be obtained to amend our certificate of incorporation; and
the authorization given to our board of directors to issue and set the terms of preferred stock without the approval 
of our stockholders. 

These provisions also could discourage proxy contests and make it more difficult for you and other stockholders to 
elect directors and take other corporate actions. As a result, these provisions could make it more difficult for a third party to 
acquire us, even if doing so would benefit our stockholders, which may limit the price that investors are willing to pay in the 
future for shares of our common stock.

Our certificate of incorporation designates courts in the State of Delaware as the sole and exclusive forum for certain types 
of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a 
favorable judicial forum for disputes with us or our directors, officers or other employees.

Our certificate of incorporation provides that, subject to limited exceptions, the Court of Chancery of the State of 

Delaware will be the sole and exclusive forum for:

•  Any derivative action or proceeding brought on our behalf;
•  Any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees 

to us or our stockholders;

•  Any action asserting a claim against us arising pursuant to any provision of the Delaware General Corporation 

Law; or

•  Any other action asserting a claim against us that is governed by the internal affairs doctrine.

In addition, our certificate of incorporation provides that if any action specified above (each is referred to herein as a 
covered proceeding), is filed in a court other than the specified Delaware courts without the approval of our board of directors 
(each is referred to herein as a foreign action), the claiming party will be deemed to have consented to (i) the personal 
jurisdiction of the specified Delaware courts in connection with any action brought in any such courts to enforce the exclusive 
forum provision described above and (ii) having service of process made upon such claiming party in any such enforcement 
action by service upon such claiming party’s counsel in the foreign action as agent for such claiming party. These provisions 
may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, 
officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees. 
Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable to, or unenforceable in 
respect of, one or more of the covered proceedings, we may incur additional costs associated with resolving such matters in 
other jurisdictions, which could adversely affect our business and financial condition.

The declaration of dividends on our common stock is within the discretion of our board of directors based upon a review of 
relevant considerations, and there is no guarantee that we will pay any dividends in the future or at levels anticipated by our 
stockholders.

On July 16, 2018, our board of directors initiated a quarterly dividend policy on shares of our common stock payable 

quarterly beginning with the second quarter of 2018. In July 2019, as a result of oilfield market conditions and other factors, 
which include collections from PREPA, our board of directors suspended the quarterly cash dividend. The decision to pay 
dividends is solely within the discretion of, and subject to approval by, our board of directors. Our board of directors’ 
determination with respect to any such dividends, including the record date, the payment date and the actual amount of the 
dividend, will depend upon our profitability and financial condition, contractual restrictions, restrictions imposed by applicable 
law and other factors that the board deems relevant at the time of such determination. Based on its evaluation of these factors, 
the board of directors may determine not to declare a dividend, or declare dividends at rates that are less than anticipated, either 
of which could reduce returns to our stockholders.

Item 2. Properties

Our corporate headquarters are located at 14201 Caliber Drive, Suite 300, Oklahoma City, Oklahoma 73134. We 

currently own 16 properties, five located in Wisconsin, five located in Texas, four located in Ohio and two located in 
Oklahoma, which are used for field offices, yards, production plants or housing. In addition to our headquarters, we also lease 
50 properties that are used for field offices, yards or transloading facilities for frac sand. We believe that our facilities are 
adequate for our current operations.

Sand Properties 

On May 26, 2017, we acquired substantially all of the assets of Chieftain Sand and Proppant, LLC and Chieftain Sand 

and Proppant Barron, LLC, unrelated third party sellers, which we collectively refer to as Chieftain, following our successful 
bid in a bankruptcy court auction, which assets included our Piranha facilities described in more detail below, for 
approximately $36.3 million. On June 5, 2017, we acquired from Gulfport, Rhino and certain affiliates of Wexford all 
outstanding membership interests in Sturgeon Acquisitions LLC, which owns Taylor Frac, LLC, Taylor Real Estate 
Investments, LLC and South River Road, LLC, which acquisition included our Taylor facilities, described in more detail below, 
in exchange for our issuance of an aggregate of 5,607,452 shares of our common stock to the sellers, with an aggregate value of 
$103.7 million as of the closing date. These acquisitions expanded our natural sand proppant business operations, added sand 
reserves and increased our production capacity.

Our natural sand proppant business mines, processes and sells high quality silica, a key input for the hydraulic 
fracturing of oil and gas wells, which we refer to as frac sand. All of our frac sand facilities are located in Wisconsin, with our 
Taylor facilities located in Jackson County, our Piranha facilities located in Barron County and our Muskie facilities located in 
Pierce County.  Our frac sand facilities consist of three dry plants with a total permitted capacity of 5.7 million tons of sand per 
year, and two wet plants that supply two of the dry plants with Northern White silica sand, which we believe is some of the 
highest quality raw frac sand available. Our Muskie dry plant in Pierce County, Wisconsin also has a wet plant, but is currently 
supplied by washed sand that is purchased from a third party supplier.

The production of our frac sand consists of three basic processes: mining, wet plant operations and dry plant 
operations.  All mining activities take place in an open pit environment, whereby we remove the topsoil, which is set aside, and 
then remove other non-economic minerals, or “overburden,” to expose the sand deposits. We then “bump” the sand using 
explosives on the mine face, which causes the sand to fall into the pit, where it is then carried by truck or conveyor to the wet 
plant operations. At our wet plants, the mined sand goes through a series of processes designed to separate the sand from 
unusable materials. The resulting wet sand is then conveyed to a wet sand stockpile where most of the water is allowed to drain 
into our on-site recycling facility, while the remaining fine grains and materials, if any, are separated through a series of 
settlement ponds. We reuse the water that does not evaporate in our wet process. Wet sand from our stockpile is then conveyed 
or trucked to our dry plants where the sand is dried, screened into specific mesh categories and stored in silos.  From the silos, 
we load sand directly into railcars or trucks, which we then ship to one of our transloading facilities or directly to our 
customers.  For information regarding our transloading facilities and shipping capabilities, see “Item 1.  Business-Our Services-
Natural Sand Proppant Services.”

Taylor.  Our Taylor facilities are located in Taylor, Wisconsin and encompass a total of approximately 393 acres. The 

site contains a mine with 25.1 million tons of proven recoverable proppant sand reserves as of December 31, 2019, based on 
estimates prepared by John T. Boyd Company, our third party mining and geological consultant. Our Taylor wet plant can 
currently process up to 2.6 million tons of wet frac sand per year. Our Taylor dry plant is adjacent to our Taylor wet plant and 
wash facilities. As of December 31, 2019, the dry plant had a rated production capacity of 2.2 million tons per year. Our current 
air permit allows us to produce up to 2.2 million tons per year of finished product. The Taylor facility includes a 150 ton per 
hour natural gas fluid bed dryer and a 100 ton per hour natural gas fluid bed dryer as well as nine high capacity screeners that 
are capable of producing 2.2 million tons of frac sand per year. During the year ended December 31, 2019, our Taylor facility 
produced 0.9 million tons of sand. Our finished product is transported via truck to our transloading facility with rail access.

Piranha.  Our Piranha facilities are located in New Auburn, Wisconsin and encompass a total of approximately 608 

acres. The site contains 41.0 million tons of proven recoverable proppant sand reserves as of December 31, 2019, based on 
estimates prepared by John T. Boyd Company. Our Piranha wet plant, which is adjacent to the mine, can process up to 4.7 
million tons of wet sand per year and is located two miles from our Piranha dry plant, to which we have year-round trucking 
access. As of December 31, 2019, the dry plant facility had a rated production capacity of 2.6 million tons per year. Our current 
air permit allows us to produce up to 3.5 million tons per year of finished product. Our Piranha facility includes a 150 ton per 
hour natural gas fired fluid bed dryer and a 200 ton per hour natural gas fluid bed dryer as well as seven high capacity screeners 
capable of producing 2.6 million tons of frac sand per year. During the year ended December 31, 2019, our Piranha facility 

50

 
 
 
 
 
produced 1.0 million tons of sand. Our finished product is loaded directly into railcars. Our Piranha facility is capable of storing 
up to 400 railcars.

Muskie.  Our Muskie facilities are located in Plum City, Wisconsin and encompass a total of approximately 40 acres. 

Although we are currently purchasing washed sand from a third party supplier, our Muskie wet plant can process up to 1.3 
million tons of wet sand per year. The site includes an indoor facility capable of washing sand year-round and an enclosed dry 
plant facility that has a rated production capacity of 2,400 tons per day. Our current air permit allows us to produce up to 0.9 
million tons per year of finished product. The facility has a 100 ton per hour natural gas fired fluid bed dryer as well as six high 
capacity screeners that are capable of producing 0.9 million tons per year. As a result of adverse market conditions, production 
at our Muskie facility has been temporarily idled since September 2018. When operating, our finished product is transported 
via truck to a third-party facility with rail access. The site does not contain any proppant sand reserves. 

Our Wisconsin dry plants are enclosed facilities capable of running year-round, regardless of the weather. Under 

normal market conditions, we typically operate our plants with work crews of ten to 15 employees. These crews typically work 
40-hour weeks, with shifts between eight and twelve hours, depending on the employee’s function. Because raw sand cannot be 
wet-processed during extremely cold temperatures, we typically mine and wet-process sand eight months out of the year at our 
Taylor and Piranha locations. Our Muskie location has an indoor wash facility, which is capable of being run year-round.

Each of our facilities undergoes regular maintenance to minimize unscheduled downtime and to ensure that the quality 

of our frac sand meets API standards and our customers’ specifications. In addition, we make capital investments in our 
facilities as required to support customer demand, and our performance goals.

We are capable of producing up to 5.7 million dry tons and 8.7 million washed tons of sand per year. The following 

tables provides information regarding our rated production capacities of our sand production facilities as of December 31, 
2019:

Mineral Reserves

The quantity and nature of the mineral reserves for our Taylor and Piranha properties are estimated by our third-party 

geologists and mining engineers, while we internally track depletion rate on an interim basis.  John T. Boyd Company, third 
party mining and geological consultants, estimated our proven sand reserves for our Taylor and Piranha properties as of 
December 31, 2019, 2018 and 2017.  There were no reserves attributable to our Muskie properties as of December 31, 2019, 
2018 and 2017.  Our external mining and geological engineers will update our reserve estimates annually, making necessary 
adjustments for operations at each location during the year and additions or surveying, drill core analysis and other tests to 
confirm the quantity and quality of the reserves.

We categorize our reserves as proven recoverable within SEC definitions.  Reserves, as defined by SEC Industry 

Guide 7, consist of sand which could be economically and legally extracted or produced at the time of the reserve 
determination. Proven reserves are defined by SEC Industry Guide 7 as those for which (a) the quantity is computed from 
dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of 
detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character 
is so well defined that size, shape, depth and mineral content of reserves are well-established. We have further limited the 
definition to apply only to sand reserves that we believe could be extracted at an average cost that is economically feasible. 

John T. Boyd updates our reserve estimates annually, making necessary adjustments for operations at each location 

during the year and additions or surveying, drill core analysis and other tests to confirm the quantity and quality of the 
reserves. To opine as to the economic viability of our reserves, John T. Boyd reviewed our financial cost and revenue per ton 
data at the time of the proven reserve determination. Our 2019 average monthly sales prices ranged from approximately $16 to 
$34 per ton free on board mine. Based on its review of our cost structure and its extensive experience with similar operations, 
John T. Boyd concluded that it is reasonable to assume that we will operate under a similar cost structure over the remaining 
life of our reserves. Based on these assumptions, and taking into account possible cost increases associated with a maturing 
mine, John T. Boyd concluded that our current operating margins are sufficient to expect continued profitability throughout the 
life of our reserves.

Our proppant sand reserves consist of Northern White silica sand, giving us access to a range of high-quality sand 

grades meeting or exceeding all API specifications, including a mix between concentrations of coarse grades (20/40 and 30/50 
mesh sands) and finer grades (40/70 and 100 mesh).  Our sample boring data and our historical production data have indicated 
that our reserves contain deposits of approximately 40% 40 mesh or coarser substrate.  The coarseness and conductivity of 
Northern White frac sand significantly enhances recovery of oil and liquids-rich gas by allowing hydrocarbons to flow more 
freely than is sometimes possible with native sand.  The low acid-solubility increases the integrity of Northern White frac sand 
relative to other proppants with higher acid-solubility, especially in shales where hydrogen sulfide and other acidic chemicals 
are co-mingled with the targeted hydrocarbons.  In addition, its crush resistant properties enable Northern White frac sand to be 
used in deeper drilling applications than the frac sand produced from many native mineral deposits. We believe that the 
coarseness, conductivity, sphericity, acid-solubility, and crush-resistant properties of our Northern White sand reserves and our 
facilities’ connectivity to rail and other transportation infrastructure afford us an advantage over 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.

Surface and Mineral Rights

For each of our frac sand facilities, we own surface and mineral rights.

Item 3. Legal Proceedings

We are a party to, or the subject of, certain investigations and legal proceedings discussed elsewhere in this annual 
report. For a description of such investigations and legal proceedings, see Note 20. Commitments and Contingencies to our 
consolidated financial statements included elsewhere in this annual report and Item 1A. “Risk Factors—Risks Related to Our 
Business and the Industries We Serve—Cobra, one of our infrastructure services subsidiaries, was party to service contracts 
with PREPA. PREPA is currently subject to bankruptcy proceedings, which were filed in July 2017 and are currently 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 
contracts is largely dependent upon funding from the Federal Emergency Management Agency or other sources. In the event 
that PREPA (i) does not have or does not obtain the funds necessary to satisfy its payment obligations to our subsidiary under 
the contracts, (ii) obtains the necessary funds but refuses to pay the amounts owed to us or (iii) 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.” and “—The outcomes of investigations and litigation relating to our contracts with PREPA may have a 
material adverse effect on our financial condition, results of operations and cash flows.”

52

 
 
 
In addition, due to the nature of our business, we are, from time to time, also involved in routine litigation or subject to 
disputes or claims related to our business activities, including workers’ compensation claims and employment related disputes. 

Except as described elsewhere in this annual report, in the opinion of our management, none of the pending litigation, 

disputes or claims against us, if decided adversely, will have a material adverse effect on our business, financial condition, 
results of operations or cash flows.

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 
safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer 
Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95.1 to this Report.

Dividends

On July 16, 2018, we initiated a quarterly dividend policy and declared our first quarterly cash dividend. Prior to this 

date, we had never declared or paid any cash dividends. In July 2019, as a result of oilfield market conditions and other factors, 
which include collections from PREPA, our board of directors suspended the quarterly cash dividend. The following table 
presents cash dividends paid during 2018 and 2019.

Our board of directors’ determination with respect to any future dividends will depend upon our profitability and 
financial condition, contractual restrictions, restrictions imposed by applicable law and other factors that the board deems 
relevant at the time of such determination. Based on its evaluation of these factors, the board of directors may determine not to 
declare a dividend, or declare dividends at rates that are less than currently anticipated.

Item 6. Selected Financial Data

This section presents our selected historical consolidated financial data. The selected historical consolidated financial data 

presented below is not intended to replace our historical consolidated financial statements. You should read the following data 
along with Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the 
consolidated financial statements and related notes, each of which is included elsewhere in this annual report.

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

55

On October 13, 2016, Mammoth Inc. priced 7,750,000 shares of its common stock in the IPO at a price to the public of 

$15.00 per share and, on October 14, 2016, Mammoth Inc.’s common stock began trading on The Nasdaq Global Select Market 
under the symbol “TUSK.” On October 19, 2016, Mammoth Inc. closed its IPO. Unless the context otherwise requires, 
references in this report to “we,” “our,” “us” or like terms, when used in a historical context for periods prior to October 12, 
2016 refer to the Partnership and its subsidiaries. References in this report to “we,” “our,” “us” or like terms, when used for 
periods beginning on or after October 12, 2016 refer to Mammoth Inc. and its subsidiaries. 

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 included in this Annual Report on Form 10-K has been recast to combine 
Sturgeon's financial results with our financial results as if the acquisition had been effective since Sturgeon commenced 
operations.

Presented below is our historical financial data for the periods and as of the dates indicated. The selected statements of 

comprehensive income (loss) and cash flow data for the years ended December 31, 2019, 2018 and 2017 and the selected 
balance sheet data as of December 31, 2019 and 2018 are derived from our audited consolidated financial statements included 
elsewhere in this annual report. The selected statements of comprehensive income (loss) and cash flow data for the years ended

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the consolidated financial statements and 
related notes included elsewhere in this 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” and the 
section entitled “Forward-Looking Statements” appearing elsewhere in this Annual Report on Form 10-K.

Overview

We are an integrated, growth-oriented company serving both the electric utility and oil and gas industries in North 

America. Our primary business objective is to grow our operations and create value for stockholders through organic growth 
opportunities and accretive acquisitions. Our suite of services includes infrastructure services, pressure pumping services, 
natural sand proppant services, drilling services and other services, which includes coil tubing, equipment rental, full service 
transportation, crude oil hauling, remote accommodations, oilfield equipment manufacturing and infrastructure engineering and 
design services. Our infrastructure services division provides construction, upgrade, maintenance and repair services to the 
electrical infrastructure industry. Our pressure pumping services division provides hydraulic fracturing, sand hauling and water 
transfer services. Our natural sand proppant services division mines, processes and sells natural sand proppant used for 
hydraulic fracturing. Our drilling services division currently provides rental equipment, such as mud motors and operational 
tools, for both vertical and horizontal drilling as well as rig moving services. In addition to these service divisions, we also 
provide coil tubing services, pressure control services, equipment rentals, full service transportation, crude oil hauling services, 
remote accommodations, oilfield equipment manufacturing and infrastructure engineering and design services. We believe that 
the services we offer play a critical role in maintaining and improving electrical infrastructure as well as in increasing the 
ultimate recovery and present value of production streams from unconventional resources. Our complementary suite of services 
provides us with the opportunity to cross-sell our services and expand our customer base and geographic positioning. 

Our transformation towards an industrial based company is ongoing. During the fourth quarter of 2019, we began 

infrastructure engineering operations focused on the transmission and distribution industry and also commenced oilfield 
equipment manufacturing operations. The startup of oilfield equipment manufacturing operations provides us with the ability to 
repair much of our existing equipment in-house, as well as the option to manufacture certain new equipment we may need in 
the future. The oilfield equipment manufacturing operations will initially serve our internal needs for our water transfer and 
equipment rental businesses, but we expect to expand into third party sales in the future. We are continuing to explore other 
opportunities to expand our business lines as we shift to a broader industrial focus.

On November 24, 2014, Mammoth Energy Holdings LLC, or Mammoth Holdings, Gulfport Energy Corporation, or 

Gulfport, and Rhino Exploration LLC, or Rhino, contributed to the Company their respective interests in the following entities: 
Bison Drilling and Field Services, LLC, or Bison Drilling; Bison Trucking LLC, or Bison Trucking; White Wing Tubular 
Services LLC, or White Wing; Barracuda Logistics LLC, or Barracuda; Panther Drilling Systems LLC, or Panther Drilling; 
Redback Energy Services LLC, or Redback Energy Services; Redback Coil Tubing LLC, or Redback Coil Tubing; Muskie 
Proppant LLC, or Muskie Proppant; Stingray Pressure Pumping LLC, or Pressure Pumping; Stingray Logistics LLC, or 
Logistics; and Great White Sand Tiger Lodging Ltd., or Sand Tiger. Upon completion of these contributions, Mammoth 
Holdings, Gulfport and Rhino beneficially owned a 68.7%, 30.5% and 0.8% equity interest, respectively, in the Partnership. 
Subsequently, the Partnership formed Redback Pumpdown Services LLC, or Pumpdown, Mr. Inspections LLC, or Mr. 
Inspections, Silverback Energy Services LLC, or Silverback, and Mammoth Inc. as wholly-owned subsidiaries.

On October 12, 2016, prior to and in connection with the IPO, the Partnership converted to a Delaware limited liability 
company named Mammoth Energy Partners LLC, or Mammoth LLC, and Mammoth Holdings, Gulfport and Rhino contributed 
their respective membership interests in Mammoth LLC to us in exchange for shares of our common stock, and Mammoth LLC 
became our wholly-owned subsidiary.

On October 19, 2016, Mammoth Inc. closed its IPO of 7,750,000 shares of common stock, of which 7,500,000 shares 
were sold by Mammoth Inc. and the remaining 250,000 shares were sold by certain selling stockholders, at a price to the public 
of $15.00 per share. Mammoth Inc.’s common stock is traded on the Nasdaq Global Select Market under the symbol “TUSK.” 
Mammoth Inc. was formed in June 2016, and did not conduct any material business operations prior to the completion of the 
IPO and the contribution described below completed on October 12, 2016 immediately prior to the IPO. Prior to the IPO, 
Mammoth Inc. was a wholly-owned subsidiary of the Partnership.

On June 5, 2017, we acquired Sturgeon Acquisitions LLC, or Sturgeon, and Sturgeon's wholly owned subsidiaries 

Taylor Frac, LLC, or Taylor Frac, Taylor Real Estate Investments, LLC, or Taylor Real Estate, and South River Road, LLC, or 
South River Road. 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 included in this Annual 
Report on Form 10-K has been recast to combine Sturgeon's financial results with our financial results as if the acquisition had 
been effective since Sturgeon commenced operations.

Our revenues, operating (loss) income and identifiable assets are primarily attributable to four reportable segments: 
infrastructure services; pressure pumping services; natural sand proppant services; and drilling services. For the year ended 
December 31, 2018, we identified three reportable segments consisting of infrastructure services, pressure pumping services 
and natural sand proppant services. Based on our assessment of FASB ASC 280, Segment Reporting, guidance at December 31, 
2019, we changed our reportable segment presentation in 2019 to include drilling services, which includes Bison Drilling, 
Bison Trucking, Panther Drilling, Mako Acquisitions and White Wing Tubular, as its own reportable segment. 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. The results of operations for 2018 and 2017 below 
have been retroactively adjusted to reflect this change in reportable segments.

Revolving Credit Facility

As of December 31, 2019, our revolving credit facility contained two financial covenants: a minimum interest 
coverage ratio (3.0 to 1.0) and a maximum leverage ratio (4.0 to 1.0).  As of December 31, 2019, we were in compliance with 
the financial covenants under our revolving credit facility. However, we believe that our adjusted EBITDA for the trailing four 
fiscal quarters would have resulted in a breach of the maximum leverage ratio and/or the interest coverage ratio as early as the 
end of the first quarter of 2020 if we did not receive payments due from PREPA before the end of such quarter.  As we believe 
that such payments from PREPA are unlikely to be received by March 31, 2020, on February 26, 2020, we amended our 
revolving credit facility to, among other things, (i) amend our financial covenants, (ii) decrease the maximum revolving 
advance amount from $185 million to $130 million, (iii) decrease the amount that the maximum revolving advance can be 
increased to (the accordion) from $350 million to $180 million, (iv) increase the applicable margin ranges from 2.00% to 
2.50% per annum in the case of the alternate base rate and from 3.00% to 3.50% per annum in the case of LIBOR, (v) increase 
the aggregate amount of permitted asset dispositions, and (vi) permit certain sale-leaseback transactions. For additional 
information regarding the amendments to our revolving credit facility, see “—Our Revolving Credit Facility” below.

2019 Highlights

•  Net loss of $79 million, or $1.76 per diluted share, and adjusted net loss of $38 million, or $0.85 per diluted share, for 
the year ended December 31, 2019. See “Non-GAAP Financial Measures” below for a reconciliation of net loss to 
adjusted net loss.

•  Adjusted EBITDA of $77 million for the year ended December 31, 2019. See “Non-GAAP Financial Measures” 

below for a reconciliation of net loss to Adjusted EBITDA.

• 

• 

Paid cash dividends of $0.25 per share. Beginning with the second quarter of 2019, we suspended the quarterly cash 
dividend in response to oilfield market conditions and other factors, which include collections from PREPA.

Formed an infrastructure engineering company focused on the transmission and distribution industry and commenced 
oilfield equipment manufacturing operations.

•  Hired a new president for our infrastructure division and recently added experienced industry personnel to key 

management positions. 

Overview of Our Industries

Energy Infrastructure Industry 

Our infrastructure services business provides construction, upgrade, maintenance and repair services to the electrical 

infrastructure industry. We offer a broad range of services on electric transmission and distribution, or T&D, networks and 
substation facilities, which include construction, upgrade, maintenance and repair of high voltage transmission lines, 
substations and lower voltage overhead and underground distribution systems. Our commercial services include the installation, 
maintenance and repair of commercial wiring. We also provide storm repair and restoration services in response to storms and 

60

 
 
other disasters. We provide infrastructure services primarily in the northeast, southwest and midwest portions of the United 
States. 

We currently have agreements in place with private utilities, public IOUs and Co-Ops. 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 Acquisitions LLC, or 
Cobra, and PREPA entered into an emergency master services agreement for repairs to PREPA’s electrical grid. The one-year 
contract, as amended, provided for payments of up to $945 million. On May 26, 2018, Cobra and PREPA entered into a second 
one-year, $900 million master services agreement to provide additional repair services and begin the initial phase of 
reconstruction of the electrical power system in Puerto Rico. Our work under each of the contracts with PREPA ended on 
March 31, 2019. 

As of December 31, 2019, PREPA owed us approximately $227 million for services we performed, excluding $42 

million of interest charged on these delinquent balances as of December 31, 2019. See Note 2. Summary of Significant 
Accounting Policies-Accounts Receivable to our consolidated financial statements included elsewhere in this annual report. 
PREPA is currently subject to bankruptcy proceedings, which were filed in July 2017 and are currently 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 contracts is 
largely dependent upon funding from the Federal Emergency Management Agency or other sources. On September 30, 2019, 
we filed a motion with the U.S. District Court for the District of Puerto Rico seeking recovery of the amounts owed to us by 
PREPA. PREPA filed a motion to stay our motion on the ground that the ongoing criminal proceedings described below against 
the former president of Cobra and two other individuals may affect our recovery of those amounts. On October 17, 2019, the 
court granted PREPA’s request to stay our motion and, on February 3, 2020, extended the stay until a status conference to be 
held on June 17, 2020. In the event PREPA (i) does not have or does not obtain the funds necessary to satisfy its obligations to 
Cobra under the contracts, (ii) obtains the necessary funds but refuses to pay the amounts owed to us or (iii) otherwise does not 
pay amounts owed to us for services performed, the receivable may not be collected and 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 and compliance reviews by government agencies and 
representatives. In this regard, on September 10, 2019, the U.S. District Court for the District of Puerto Rico unsealed an 
indictment that charged the former president of Cobra with conspiracy, wire fraud, false statements and disaster fraud. Two 
other individuals were also charged in the indictment. The indictment is focused on the interactions between a former FEMA 
official and the former President of Cobra. Neither we nor any of our subsidiaries were charged in the indictment. We are 
continuing to cooperate with the related investigation. We are also subject to investigations and legal proceedings related to our 
contracts with PREPA. Given the uncertainty inherent in the criminal litigation, investigations and legal proceedings, it is not 
possible at this time to determine the potential outcome or other potential impacts that they could have on us. See Note 20. 
Commitments and Contingencies to our consolidated financial statements included elsewhere in this annual report for 
additional information regarding these investigations and proceedings. Further, as noted above, our contracts with PREPA have 
concluded and we have not obtained, and there can be no assurance that we will be able to obtain, one or more contracts with 
PREPA or other customers to replace the level of services that we provided to PREPA under our previous contracts. 

Since the completion of our work in Puerto Rico on March 31, 2019, we focused on right-sizing our infrastructure 
operations and performing required maintenance on our equipment, which had been subjected to harsh working conditions. 
This process, with its associated costs, was completed during the fourth quarter of 2019.

Demand for our infrastructure services in the continental United States has increased since we began operations in 

2017. We had a total of approximately 140 transmission and distribution crews as of December 31, 2019, as compared to 
approximately 105 at December 31, 2018 and approximately 50 at December 31, 2017. Transmission crew size varies based 
upon the scope of the project and factors such as voltage, structure type, number of conductors and type of foundation. Each 
distribution crew generally consists of five employees. These transmission and distribution crews are working for multiple 
utilities primarily across the northeastern, midwestern and southwestern portions of the United States. We recently hired a new 
president for our infrastructure division and have added experienced industry personnel to key management positions. With this 
team in place, we believe we will be able to grow our customer base and increase our revenues in the continental United States 
over the coming years. We also believe that the skill sets and experience of our crews will afford us enhanced bidding 
opportunities in both the U.S. and overseas.

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 
61

 
 
 
 
 
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 prices of oil and natural gas. 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 2019, oil prices fluctuated between a low of $45.41 on January 1, 2019 and a high of $66.30 on April 23, 2019, 
and averaged $57.03 per barrel for the year. Certain factors related to world politics and major oil producers caused fluctuations 
in the oil price during 2019. However, overall, the price of oil stayed relatively stable throughout the year. 

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. We experienced a weakening 
in demand for our oilfield services beginning in the third quarter of 2019, which continued throughout the fourth quarter of 
2019 as a result of budget exhaustion and capital discipline from our customers. In addition, other factors, including access to 
capital and the need to refinance or repay maturing debt, have had a significant influence on some of our customers' capital 
budgets and activity levels. While we still expect commodity prices to be the primary driver of capex spending and industry 
activity levels in the future, other factors may play a significant role in the ultimate level of capex spending by the companies 
that use our completion and production, natural sand proppant and directional drilling businesses. 

During 2019, we experienced lower utilization rates and pricing for our oil and natural gas services, including our 

pressure pumping, contract drilling, coil tubing and directional drilling equipment and services, as compared to 2018. Further, 
in response to market conditions, in July 2019 we temporarily shut down our cementing and acidizing operations and flowback 
operations. Additionally, in December 2019 we temporarily shut down our contract drilling operations. We continue to monitor 
the market to determine if and when we can recommence these services. Based on current feedback from our exploration and 
production customers, we expect them to take a cautious approach to activity levels in 2020 given the recent volatility in oil 
prices and investor sentiment calling for activities to remain within or below cash flows. Market fundamentals are challenging 
for our oil field businesses. Although we believe the reported retirement of equipment across the industry is beginning to help 
the market, pricing and utilization for our oil field businesses are, and are expected to remain depressed for the foreseeable 
future. We intend to closely monitor our cost structure in response to market conditions and pursue cost savings where possible. 
Further, a significant portion of our revenue from our pressure pumping business is derived from Gulfport pursuant to a 
contract that expires in December 2021. On December 28, 2019, Gulfport filed a lawsuit alleging our breach of this contract 
and seeking to terminate the contract and recover damages for alleged overpayments, audit costs and legal fees. We believe this 
action is without merit and will vigorously defend the lawsuit. However, the termination of our relationship with Gulfport, or 
nonrenewal of our contract with Gulfport, or one or more of our other customers, if not replaced with comparable or greater 
levels of service from other customers, would result in lower utilization rates for our pressure pumping equipment and, as a 
result, would have a material adverse effect on our business, financial condition, results of operations and cash flow. 

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. 

In 2018 and 2019, several new and existing suppliers completed planned capacity additions of frac sand supply, 

particularly in the Permian Basin. The industry expansion, coupled with increased capital discipline and budget exhaustion, 
caused the frac sand market to become oversupplied, particularly in finer grades, during the second half of 2019. With the frac 
sand market oversupplied, pricing for certain grades has fallen significantly from the peaks experienced throughout 2018 and 
during the first half of 2019. This oversupply resulted in several industry participants idling and closing high cost mines in an 
attempt to restore the supply and demand balance and reduce the number of industry participants. Nevertheless, demand for our 
sand declined significantly in the second half of 2019 as a result of increased capital discipline by our customers and budget 
exhaustion, among other factors. We cannot predict if and when demand and pricing will recover sufficiently to return our 
natural sand proppant services segment to profitability. 

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 
62

 
 
 
 
 
 
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 and we do not believe they had an impact on our operations in 2019. Production at 
our Piranha facility was not impacted by these rail constraints. 

Further, as a result of adverse market conditions, production at our Muskie sand facility in Pierce County, Wisconsin 

has been temporarily idled since September 2018. Our Taylor sand facility in Taylor, Wisconsin and Piranha sand facility in 
New Auburn, Wisconsin are currently running at 20% to 25% capacity. Our contracted capacity has provided a strong baseline 
of business, which has kept our Taylor and Piranha plants operating and our costs low. Our blended production costs have 
declined 24% from $15.54 during 2018 to $11.82 during 2019.

Our subsidiary Muskie Proppant is a party to a contract with Gulfport under which we sell and deliver specified 

amounts of sand to Gulfport. The agreement, as amended, has a term ending in December 2021. This agreement is not subject 
to the current disputes with Gulfport regarding the our pressure pumping contract.

Revenue. Revenue for 2019 decreased $1.1 billion, or 63%, to $625 million from $1.7 billion for 2018. The decline in 

total revenue is primarily attributable to a $868 million decrease in infrastructure services revenue, representing 81% of the 
overall decrease. Additionally, pressure pumping services and natural sand proppant services revenue decreased $123 million 
and $68 million, respectively, representing 12% and 6% of the overall decrease. Revenue derived from related parties was $130 
million, or 21% of our total revenue, for 2019 and $143 million, or 8% of our total revenue, for 2018. Substantially all of our 
related party revenue is derived from Gulfport under pressure pumping and sand contracts. Revenue by division was as follows:

Infrastructure Services. Infrastructure services division revenue decreased $868 million, or 80%, to $214 

million for 2019 from $1.1 billion for 2018 primarily due to the conclusion on March 31, 2019 of the work we 
performed under our contracts 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 “Overview of Our 
Industries - Electrical Infrastructure Industry” above. Revenue from our operations in the continental United States 
increased $58 million, or 96%, to $118 million for 2019 from $60 million for 2018.

Pressure Pumping Services. Pressure pumping services division revenue decreased $123 million, or 33%, to 

$246 million for 2019 from $369 million for 2018. Revenue derived from related parties was $91 million, or 37% of 
total pressure pumping revenue, for 2019 and $96 million, or 26% of total pressure pumping revenue, for 2018. 
Substantially all of our related party revenue is derived from Gulfport under a pressure pumping contract. For 
additional information regarding the status of this contract, see Note 20. Commitments and Contingencies to our 
consolidated financial statements included elsewhere in this annual report. Intersegment revenue, consisting primarily 
of revenue derived from our sand segment, totaled $4 million and $7 million, respectively, for 2019 and 2018.

The decrease in our pressure pumping services revenue was primarily driven by a decline in pricing as well 
as a decline in utilization. The number of stages completed decreased 14% to 5,378 for 2019 from 6,245 for 2018. An 
average of 2.4 of our fleets were active throughout 2019 compared to 3.6 fleets for 2018. 

Natural Sand Proppant Services. Natural sand proppant services division revenue decreased $68 million, or 
40%, to $100 million for 2019, from $168 million for 2018. Revenue derived from related parties was $28 million, or 
28% of total sand revenue, for 2019 and $25 million, or 15% of total sand revenue, for 2018. All of our related party 
revenue is derived from Gulfport under a contract effective through December 31, 2021. Intersegment revenue, 
consisting primarily of revenue derived from our pressure pumping segment, totaled $30 million, or 30% of total sand 
revenue, for 2019 and $67 million, or 40% of total sand revenue, for 2018.

The decrease in our natural sand proppant services revenue was primarily attributable to a 25% decline in 

tons of sand sold from approximately 2.7 million tons in 2018 to 2.0 million tons in 2019 coupled with a 24% decline 
in average price per ton of sand sold from $39.16 in 2018 to $29.70 in 2019. 

Drilling Services. Drilling services division revenue decreased $35 million, or 52%, to $32 million for 2019, 

from $67 million for 2018. Revenue derived from related parties, consisting primarily of directional drilling revenue 
from El Toro Resources LLC, was $1 million for each of 2019 and 2018. The decline in our drilling services revenue 
was primarily attributable to decreases in revenue for our contract land drilling and directional drilling businesses of 
$19 million and $11 million, respectively, due to declines in utilization. Our average active rigs decreased from 4.3 in 
2018 to 1.4 in 2019. Directional drilling utilization declined from 49% in 2018 to 30% in 2019.

Other Services. Revenue from other services, consisting of revenue derived from our coil tubing, pressure 
control, flowback, cementing, acidizing, equipment rental, crude oil hauling, full service transportation and remote 
accommodation businesses, decreased $15 million, or 18%, to $69 million for 2019 from $84 million for 2018. 
Revenue derived from related parties, consisting primarily of equipment rental and cementing revenue from Gulfport, 
was $9 million, or 13% of total other services revenue, for 2019 and $21 million, or 25% of total other services 
revenue, for 2018. Intersegment revenue, consisting primarily of revenue derived from our infrastructure and pressure 
pumping segments, totaled $2 million and $6 million, respectively, for 2019 and 2018.

The decrease in other services revenue was primarily due to a decline in utilization from 39% in 2018 to 17% 
in 2019 for our coil tubing business. Additionally, due to market conditions, we temporarily shut down our cementing 
and acidizing operations as well as our flowback operations during the third quarter of 2019 resulting in a decline in 
revenue. We continue to monitor market conditions to evaluate if and when we can recommence providing these 
services. These decreases were partially offset by an increase in activity for our equipment rental business. An average 

64

 
 
 
 
 
 
 
 
 
of 557 pieces of equipment were rented during 2019, an increase of 41% from 395 pieces of equipment rented during 
2018. 

Cost of Revenue (exclusive of depreciation, depletion, amortization and accretion expense). Cost of revenue, 

exclusive of depreciation, depletion, amortization and accretion expense, decreased $550 million from $1.1 billion, or 65% of 
total revenue, for 2018 to $544 million, or 87% of total revenue, for 2019. The decrease was primarily due to a decline in 
activity across all business lines. Cost of revenue by operating division was as follows:

Infrastructure Services. Infrastructure services division cost of revenue, exclusive of depreciation and 
amortization expense, decreased $439 million from $611 million for 2018 to $172 million for 2019. The decline is due 
to the conclusion on March 31, 2019 of the work we performed under our contracts with PREPA for repairs to Puerto 
Rico's electrical grid as a result of Hurricane Maria. As a percentage of revenue, cost of revenue, exclusive of 
depreciation and amortization expense of $31 million in 2019 and $20 million in 2018, was 80% and 56%, 
respectively, for 2019 and 2018. 

Pressure Pumping Services. Pressure pumping services division cost of revenue, exclusive of depreciation 

and amortization expense, decreased $84 million, or 29%, from $294 million for 2018 to $210 million for 2019 
primarily due to a decline in activity. As a percentage of revenue, our pressure pumping services division cost of 
revenue, exclusive of depreciation and amortization expense of $40 million in 2019 and $51 million in 2018, was 85% 
and 79%, respectively, for 2019 and 2018. The increase in costs as a percentage of revenue was primarily due to a 
decline in utilization. 

Natural Sand Proppant Services. Natural sand proppant services division cost of revenue, exclusive of 
depreciation, depletion and accretion expense, decreased $43 million, or 32%, from $133 million for 2018 to $90 
million for 2019 primarily due to a decrease in cost of goods sold as well as a 24% decline in production costs per ton 
of sand. As a percentage of revenue, cost of revenue, exclusive of depreciation, depletion and accretion expense of $14 
million in both 2019 and 2018, was 91% and 79%, respectively, for 2019 and 2018. The increase in cost as a 
percentage of revenue is primarily due to a 24% decline in average price per ton of sand sold.

Drilling Services. Drilling services division cost of revenue, exclusive of depreciation and amortization 

expense, decreased $24 million, or 39%, from $61 million for 2018 to $37 million for 2019 primarily due a decline in 
activity for our contract land drilling and directional drilling businesses. As a percentage of revenue, cost of revenue, 
exclusive of depreciation and amortization expense of $13 million in 2019 and $18 million in 2018, was 114% and 
91%, respectively, for 2019 and 2018. The increase is primarily due to an increase in labor-related costs as a 
percentage of revenue. 

Other Services. Other services cost of revenue, exclusive of depreciation and amortization expense, 
decreased $4 million, or 5%, from $76 million for 2018 to $72 million for 2019 primarily due to a decline in costs for 
our coil tubing business as a result of reduced activity. Additionally, due to market conditions, we temporarily shut 
down our cementing and acidizing operations as well as our flowback operations during the third quarter of 2019 
resulting in a decline in cost of revenue. We continue to monitor market conditions to evaluate if and when we can 
recommence providing these services. These declines were partially offset by an increase in costs for our equipment 
rental and crude oil hauling businesses. As a percentage of revenue, cost of revenue, exclusive of depreciation and 
amortization expense of $18 million and $16 million in 2019 and 2018, was 104% and 91%, respectively, for 2019 and 
2018. 

Selling, General and Administrative Expenses. Selling, general and administrative expenses, or SG&A, represent the 

costs associated with managing and supporting our operations. Following is a breakout of SG&A expenses for the periods

During the year ended December 31, 2018, we received payment for amounts previously reserved in 2017. As a result, during the year ended 
December 31, 2018, we reversed bad debt expense of $16 million recognized in 2017.
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 decreased 
$3 million, or 2%, to $117 million for 2019 from $120 million in 2018. The decrease is primarily due to a decline in intangible 
asset amortization expense partially offset by an increase in property and equipment depreciation expense. 

Impairment of Goodwill. We recorded impairment of goodwill of $34 million and $3 million, respectively, in 2019 

and 2018. As a result of our annual assessment of goodwill, we determined that the carrying value of goodwill for certain of our 
entities exceeded their fair values at December 31, 2019, resulting in impairment expense of $30 million. During 2019, we 
temporarily shut down our cementing and acidizing operations, resulting in impairment of goodwill totaling $3 million. We 
recorded expense of $3 million in 2018 related to impairment of goodwill as a result of the movement of certain cementing 
equipment from the Utica Shale to the Permian Basin.

Impairment of Other Long-lived Assets. We recorded impairments of other long-lived assets of $7 million and $6 

million, respectively, in 2019 and 2018. During 2019, we temporarily shut down our our flowback operations, resulting in fixed 
asset impairments of $4 million during 2019. Additionally, we recorded impairment expense $3 million related to specified 
drilling rigs and $1 million related to WTL's customer relationship intangible asset during 2019. We recorded impairment 
expense of $4 million related to specified drilling rigs in 2018 and $1 million related to impairment of intangible assets as a 
result of the movement of certain cementing equipment from the Utica shale to the Permian basin. 

Operating (Loss) Income. Operating income decreased $522 million to an operating loss of $128 million for 2019 

compared to operating income of $394 million for 2018. The decrease is primarily due to a $438 million decline in operating 
income for our infrastructure services division due to a decline in activity. 

Interest Expense, net. Interest expense, net increased $2 million to $5 million during 2019 compared to $3 million 

during 2018 primarily due to an increase in average borrowings outstanding under our revolving credit facility. 

Other Income (Expense), net. Other income, net increased $44 million during 2019 compared to 2018 primarily due 

to the recognition of interest on trade accounts receivable totaling $42 million pursuant to the terms of our contracts with 
PREPA. 

Income Taxes. During 2019, we recorded an income tax benefit of $12 million on pre-tax loss of $91 million 
compared to income tax expense of $153 million on pre-tax income of $389 million for 2018. Our effective tax rate was 13.3% 
for 2019 compared to 39.4% for 2018. Our tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and 
the relative amounts of income we earn in those jurisdictions, as well as discrete items, such as return to provision adjustments, 
goodwill impairment and equity based compensation that may not be consistent from year to year. See Note 14 to our 
consolidated financial statements for additional detail regarding our change in tax expense.

Revenue. Revenue for 2018 increased $999 million, or 144%, to $1.7 billion from $691 million for 2017. The increase 

in total revenue is primarily attributable to a $858 million increase in infrastructure services revenue, representing 86% of the 
overall increase. Additionally, pressure pumping services revenue increased $90 million, representing 9% of the overall 
increase. Revenue derived from related parties was $143 million, or 8% of our total revenues, for 2018 and $209 million, or 
30% of our total revenues, for 2017. Substantially all of our related party revenue is derived from Gulfport under pressure 
pumping and sand contracts. Revenue by division was as follows:

Infrastructure Services. Infrastructure services division revenue increased $858 million, or 382%, to $1 

billion for 2018 from $224 million for 2017. For 2018 and 2017, we generated 94% and 90%, respectively, of total 
infrastructure services revenue from our contracts with PREPA for repairs to and reconstruction of Puerto Rico's 
electrical grid as a result of Hurricane Maria. For additional information regarding our contracts with PREPA and our 
infrastructure services, see “Overview of Our Industries - Electrical Infrastructure Industry” above.

67

 
 
Pressure Pumping Services. Pressure pumping services division revenue increased $90 million, or 32%, to 
$369 million for 2018 from $279 million for 2017. Revenue derived from related parties was $96 million, or 26% of 
total pressure pumping revenue, for 2018 and $144 million, or 52% of total pressure pumping revenue, for 2017. 
Substantially all of our related party revenue was derived from Gulfport under a pressure pumping contract. For 
additional information regarding the status of this contract, see Note 20. Commitments and Contingencies to our 
consolidated financial statements included elsewhere in this annual report. Intersegment revenue, consisting primarily 
of revenue derived from our sand segment, was $7 million and $2 million, respectively, for 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 revenues of $148 million in 2018 compared to $100 million in 2017. Additionally, the 
number of stages completed increased to 6,245 for 2018 from 5,139 for 2017.

Natural Sand Proppant Services. Natural sand proppant services division revenue increased $51 million, or 
44%, to $168 million for 2018, from $117 million for 2017. Revenue derived from related parties was $25 million, or 
15% of total sand revenues, for 2018 and $43 million, or 37% of total sand revenues, for 2017. Substantially all of our 
related party revenue was derived from Gulfport under a contract effective through December 31, 2021. Intersegment 
revenue, consisting primarily of revenue derived from our pressure pumping segment, was $67 million, or 40% of 
total sand revenue, for 2018 and $27 million, or 23% of total sand revenue, for 2017. 

The increase in our natural sand proppant services revenue was primarily attributable to a 59% increase in 

tons of sand sold from approximately 1.7 million tons in 2017 to 2.7 million tons in 2018. 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 $38 million to our natural sand proppant services 
division in 2018 compared to $23 million in 2017.

Drilling Services. Drilling services division revenue increased $16 million, or 31%, to $67 million for 2018, 
from $51 million for 2017. Revenue derived from related parties, consisting primarily of directional drilling revenue 
from Gulfport and El Toro Resources LLC, was $1 million and $4 million, respectively, for 2018 and 2017. Revenue 
for our directional drilling services increased $13 million in 2018 compared to 2017 primarily due to an increase in 
utilization from 27% in 2017 to 49% in 2018. 

Other Services. Revenue from other services, consisting of revenue derived from our coil tubing, pressure 

control, flowback, cementing, equipment rental and remote accommodation businesses, increased $32 million, or 
62%, to $84 million for 2018 from $52 million for 2017. Revenue derived from related parties, consisting primarily of 
equipment rental and cementing revenue from Gulfport, was $21 million, or 25% of total other services revenue, for 
2018 and $18 million, or 35% of total other services revenue, for 2017. Intersegment revenue, consisting primarily of 
revenue derived from our infrastructure and pressure pumping segments, was $6 million and $2 million, respectively 
for 2018 and 2017.

Revenue for Stingray Cementing and Stingray Energy, which we acquired in June 2017, increased $16 

million for 2018 compared to 2017. During the second quarter of 2018, we acquired RTS, a cementing and acidizing 
business, and WTL, a crude oil hauling business. These businesses contributed revenue of $14 million during 2018. 
Revenue from our coil tubing, pressure control and flowback services increased $7 million for 2018 compared 
to 2017 primarily due to increases in utilization. These increases were partially offset by a $6 million decrease in 
revenue from our remote accommodations business due to a decline in utilization.

Cost of Revenue (exclusive of depreciation, depletion, amortization and accretion). Cost of revenue, exclusive of 

depreciation, depletion, amortization and accretion expense, increased $611 million from $483 million, or 70% of total revenue, 
for 2017 to $1.1 billion, or 65% of total revenue, for 2018. The increase was primarily due to an expansion of our service 
offerings into the infrastructure services business, which represented a $489 million increase in cost of revenue, as well as an 
increase in pressure pumping division costs of $83 million, primarily related to the addition of three new fleets in 2017. Cost of 
revenue by division was as follows:

Infrastructure Services. Infrastructure services division cost of revenue, exclusive of depreciation and 

amortization expense, increased $489 million from $122 million for 2017 to $611 million for 2018. 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, contract labor and travel, meals and lodging expense. As a percentage of revenue, 

68

 
 
 
 
 
 
 
 
 
cost of revenue, exclusive of depreciation and amortization expense of $20 million in 2018 and $3 million in 2017, 
was 56% and 54%, respectively, for 2018 and 2017.

Pressure Pumping Services. Pressure pumping services division cost of revenue, exclusive of depreciation 
and amortization expense, increased $83 million, or 39%, from $211 million for 2017 to $294 million for 2018. The 
increase was primarily due to the expansion of services into the SCOOP/STACK and 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 $51 million in 2018 and $45 million in 2017, was 79% and 76%, 
respectively, for 2018 and 2017. 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.

Natural Sand Proppant Services. Natural sand proppant services division cost of revenue, exclusive of 
depreciation, depletion and accretion expense, increased $40 million, or 43%, from $93 million for 2017 to $133 
million for 2018 primarily due to an increase in cost of goods sold as a result of a 59% increase in tons of sand sold 
in 2018 compared to 2017, partially offset by a decrease in production costs per ton of sand in 2018. As a percentage 
of revenue, cost of revenue, exclusive of depreciation, depletion and accretion expense of $14 million in 2018 and $9 
million in 2017, was 79% for both 2018 and 2017.

Drilling Services. Drilling services cost of revenue, exclusive of depreciation and amortization expense, 

increased $14 million, or 30%, from $47 million for 2017 to $61 million for 2018 primarily due to an increase in costs 
for our directional drilling business due to increased utilization. As a percentage of revenue, our drilling services 
division cost of revenue, exclusive of depreciation and amortization expense of $18 million in 2018 and $20 million 
in 2017, was 91% and 93%, respectively, for 2018 and 2017. 

Other Services. Other services cost of revenue, exclusive of depreciation and amortization expense, increased 

$34 million, or 81%, from $42 million for 2017 to $76 million for 2018, primarily due to the acquisition of Stingray 
Cementing and Stingray Energy, partially offset by a decline in costs for our remote accommodations business and 
declines in labor-related costs and repairs and maintenance expense for our coil tubing and flowback businesses. As a 
percentage of revenue, cost of revenue, exclusive of depreciation and amortization expense of $16 million in 2018 and 
$14 million in 2017, was 91% and 81%, respectively, for 2018 and 2017. 

Selling, General and Administrative Expenses. Selling, general and administrative expenses represent the costs 

associated with managing and supporting our operations. These expenses increased $23 million, or 47%, to $73 million for 
2018, from $50 million for 2017. Following is a breakout of SG&A expenses for the periods indicated (in thousands):

Depreciation, Depletion, Amortization and Accretion. Depreciation, depletion, accretion and amortization increased 
$28 million, or 30%, to $120 million for 2018 from $92 million in 2017. The increase is primarily attributable to an increase in 

69

 
 
 
 
 
 
property and equipment purchases in the second half of 2017 and 2018, resulting in increased depreciation expense. 
Additionally, depletion expense increased in 2018 as a result of the Chieftain assets purchased in 2017.

Impairment of Goodwill. We recorded expense of $3 million in 2018 related to impairment of goodwill as a result of 

the movement of certain cementing equipment from the Utica Shale to the Permian Basin.

Impairment of Other Long-lived Assets. We recorded an impairment of other long-lived assets of $6 million in 2018, 
of which $4 million related to specified drilling rigs and $1 million related to impairment of intangible assets as a result of the 
movement of certain cementing equipment from the Utica Shale to the Permian Basin. Impairments were $4 million in 2017, 
primarily related to specified drilling rig assets.

Operating Income (Loss). Operating income increased $331 million, or 525%, to $394 million for 2018 compared to 
$63 million for 2017. The increase was primarily the result of an expansion of our infrastructure businesses, which accounted 
for $346 million of the increase in operating income and a $9 million increase in natural sand proppant operating income. 
These were partially offset by a $19 million decrease in pressure pumping operating income primarily due to the recognition of 
non-cash equity compensation expense during 2018.

Interest Expense, net. Interest expense, net decreased $1 million, or 26%, to $3 million during 2018 compared to $4 
million during 2017. The decline in interest expense was attributable to a decrease in average borrowings on our credit facility 
during 2018 compared to 2017.

Bargain Purchase Gain. The purchase of the Chieftain assets resulted in a bargain purchase gain of $4 million 

for 2017. See Note 4 to our consolidated financial statements included elsewhere in this annual report for more information.

Other Expense, net. Non-operating charges resulted in other expense, net, of $2 million for 2018 compared to $1 

million for 2017. The 2018 amount included $1 million of loss on the disposal of assets during the period compared to a 
nominal loss for 2017.

Income Taxes. During 2018, we recorded income tax expense of $153 million on pre-tax income of $389 

million compared to income tax expense of $3 million on pre-tax loss of $62 million for 2017. Our effective tax rate was 39.4% 
for 2018 and 4.9% for 2017. 2017 included the recognition of a $31 million credit related to the Tax Act enacted in 2017. Our 
tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and the relative amounts of income we earn in 
those jurisdictions, as well as discrete items, such as equity based compensation that may not be consistent from year to year. 
See Note 14 to our consolidated financial statements for additional detail regarding our change in tax expense.

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, amortization and accretion, impairment of long-lived assets, inventory 
obsolescence charges, acquisition related costs, public offering costs, equity based compensation, stock based compensation, 
bargain purchase gain, interest expense, net, other (income) expense, net (which is comprised of the (gain) or loss on disposal 
of long-lived assets and interest on delinquent accounts receivable) and provision (benefit) for income taxes, further adjusted to 
add back interest on trade accounts receivable. 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.

The following tables also provide a reconciliation of Adjusted EBITDA to the GAAP financial measure of net income 

or (loss) for each of our operating segments for the specified periods (in thousands).

Adjusted Net (Loss) Income and Adjusted (Loss) Earnings per Share

Adjusted net (loss) income and adjusted basic and diluted (loss) 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 impairment expense and equity based compensation, that may not be indicative of the Company's ongoing operating results. 
Adjusted net (loss) income and adjusted (loss) earnings per share should not be considered in isolation or as a substitute for net 
(loss) income and (loss) 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 (loss) income and adjusted 
(loss) earnings per share to the GAAP financial measures of net (loss) income and (loss) earnings per share for the periods 
specified.

We require capital to fund ongoing operations, including maintenance expenditures on our existing fleet of equipment, 
organic growth initiatives, investments and acquisitions. Our primary sources of liquidity have been cash on hand, borrowings 
under our revolving credit facility and cash flows from operations. Our primary uses of capital have been for investing in 
property and equipment used to provide our services, to acquire complementary businesses and to pay dividends to our 
stockholders. In July 2019, as a result of oilfield market conditions as well as other factors, which include collections from 
PREPA, our board of directors suspended the quarterly cash dividend. 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 December 31, 2019, we had outstanding borrowing under our revolving credit facility of $80 million.

a.  Net working capital (less cash) is a non-GAAP measure and, as of December 31, 2019, is calculated by subtracting total 

current liabilities of $130 million and cash and cash equivalents of $6 million from total current assets of $407 million. As 
of December 31, 2018, net working capital (less cash) is calculated by subtracting total current liabilities of $234 million 
and cash and cash equivalents of $68 million from total current assets of $450 million.

As of February 26, 2020, we had $87 million in borrowings outstanding under our revolving credit facility, leaving an 

aggregate of $21 million of available borrowing capacity under this facility, after giving effect to our recent amendment that 
reduced the maximum revolving advance amount to $130 million. The available borrowing capacity is reduced by (i) a 
minimum excess availability covenant of 10% of the maximum revolving advance amount and (ii) $9 million of outstanding 
letters of credit.

Net cash (used in) provided by operating activities was ($95) million, $387 million and $58 million, respectively, for 

the years ended December 31, 2019, 2018 and 2017. The decrease in operating cash flows from 2018 to 2019 was primarily 
attributable to a decline in activity for our infrastructure services segment as well as a timing difference between cash outflows 
for income tax payments and cash inflows for accounts receivable. The increase in operating cash flows from 2017 to 2018 was 
primarily attributable to an increase in net income as a result of the expansion of our infrastructure services business.  

Investing Activities

Net cash used in investing activities was $33 million, $212 million and $172 million, respectively, for the years ended 
December 31, 2019, 2018 and 2017. Net cash used for acquisitions totaled $21 million and $42 million, respectively, for 2018 
and 2017. The Company did not make any acquisitions during 2019. Substantially all remaining cash used in investing 
activities was used to purchase property and equipment that is utilized to provide our services.

Financing Activities

Net cash provided by (used in) financing activities was $67 million, ($113) million and $91 million, respectively, for 

the years ended December 31, 2019, 2018 and 2017. Net cash provided by financing activities for the year ended December 31, 
2019 was primarily attributable to net borrowings under our revolving credit facility of $80 million, partially offset by 
dividends paid of $11 million. Net cash used in financing activities for the year ended December 31, 2018 was primarily 
attributable to net repayments under our revolving credit facility of $100 million and cash dividends paid totaling $11 million. 
Net cash provided by financing activities for the year ended December 31, 2017 was primarily attributable to net borrowings 
under our revolving credit facility of $100 million, which was partially offset by the repayment of acquiree debt of $9 million. 

Effect of Foreign Exchange Rate on Cash 

The effect of foreign exchange rate on cash was $0.1 million, ($0.1) million and a nominal amount, respectively, for 

the years ended December 31, 2019, 2018 and 2017. The year-over-year effect 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 $277 million and $216 million, respectively, at December 31, 2019 and 2018. Our cash 

balances totaled $6 million and $68 million, respectively, at December 31, 2019 and 2018. 

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 facility with the lenders party thereto and PNC Bank, National Association, as a lender and as 
administrative agent for the lenders, which among other things, (i) extended the maturity date to October 19, 2023, 
(ii) increased 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) increased the letter of credit sublimit to 20% of the 
maximum revolving advance amount and (iv) decreased the interest rates applicable to loans. On November 5, 2019, we 
entered into a first amendment to our amended and restated revolving credit facility, to amend the interest coverage ratio 
definition to give accrual treatment to certain cash taxes included in the ratio calculation. As a result, certain cash tax payments 
that were made in 2019 were treated as if they were made in 2018, the year in which the income related to such tax payments 
was actually received. As of December 31, 2019, we were in compliance with the financial covenants under our revolving 
credit facility. However, we believe that our adjusted EBITDA for the trailing four fiscal quarters would have resulted in a 
breach of the maximum leverage ratio and/or the interest coverage ratio as early as the end of the first quarter of 2020 if we did 
not receive payments due from PREPA before the end of such quarter.  As we believe that such payments from PREPA are 
unlikely to be received by March 31, 2020, on February 26, 2020, we further amended our revolving credit facility to, among 
other things, (i) amend our financial covenants, as outlined below, (ii) decrease the maximum revolving advance amount from 
$185 million to $130 million, (iii) decrease the amount that the maximum revolving advance can be increased to (the 
accordion) from $350 million to $180 million, (iv) increase the applicable margin ranges from 2.00% to 2.50% per annum in 
the case of the alternate base rate and from 3.00% to 3.50% per annum in the case of LIBOR, (v) increase the aggregate amount 
of permitted asset dispositions, and (vi) permit certain sale-leaseback transactions.

The financial covenants under our revolving credit facility were amended as follows:

• 
• 

• 

• 

the minimum interest coverage ratio of 3.0 to 1.0 was eliminated;
the maximum leverage coverage ratio of 4.0 to 1.0 was eliminated for the first two fiscal quarters of 2020 and, 
beginning with the fiscal quarter ended September 30, 2020, changed to 2.5 to 1.0;
beginning with the fiscal quarter ended September 30, 2020, a minimum fixed charge coverage ratio of at least 1.1 to 
1.0 was added; and
from the effective date of February 26, 2020 through September 30, 2020, a minimum excess availability covenant of 
10% of the maximum revolving advance amount was added.

We cannot assure you that we will be able to remain in compliance with the covenants contained in our revolving 

credit facility as amended and restated. If an event of default occurs under our revolving credit facility and remains uncured, it 

76

 
 
 
 
 
could have a material adverse affect on our business, financial condition, results of operations and cash flows. The lenders (i) 
would not be required to lend any additional amounts to us, (ii) could elect to declare all outstanding borrowings, together with 
accrued and unpaid interest and fees, to be due and payable, and (iii) may have the ability to require us to apply all of our 
available cash to repay our outstanding borrowings. 

At December 31, 2019, we had outstanding borrowings under our revolving credit facility of $80.0 million. At 
February 26, 2020, we had $87.4 million in borrowings outstanding under our revolving credit facility, leaving an aggregate of 
$20.6 million of available borrowing capacity under this facility, after giving effect to our recent amendment that (i) reduced 
the maximum revolving advance amount to $130 million and imposed a minimum excess availability covenant of 10% of the 
maximum revolving advance amount and (ii) $9.0 million of outstanding letters of credit.

Capital Requirements and Sources of Liquidity

During 2019, our capital expenditures totaled $36 million and included $6 million in our infrastructure segment 
primarily related to truck, tooling and equipment purchases for new crews, $15 million in our pressure pumping segment 
primarily related to various pressure pumping and water transfer equipment, $3 million in our natural sand proppant services 
segment for various maintenance equipment, $3 million in our drilling services segment primarily for upgrades to our rig fleet 
and $9 million for our other businesses primarily related to equipment additions for our equipment rental business. 

During 2020, we currently estimate that our aggregate capital expenditures will be up to $20 million, depending upon 

industry conditions and our financial results. These capital expenditures include $8 million in our infrastructure segment for 
assets for additional crews, $8 million in our pressure pumping segment for conversion of a portion of our fleet to include DGB 
capabilities, maintenance to our existing pressure pumping fleet and additional water transfer equipment and $4 million for our 
other divisions, primarily for additional equipment for our rental business. However, if industry conditions remain the same or 
weaken further, we expect that our capital expenditures for 2020 will be materially less.

We believe that our cash on hand, operating cash flow and available borrowings under our 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 (including receipt of payments from our customers, including PREPA and Gulfport). Further, significant additional 
capital expenditures could be required to conduct our operations. Accordingly, there can be no assurance that operations and 
other capital resources, including potential sales of assets or businesses, will provide cash in sufficient amounts to meet our 
operating needs and/or maintain planned or future levels of capital expenditures. In addition, while we regularly evaluate 
acquisition opportunities, we do not have a specific acquisition budget for 2020 since the timing and size of acquisitions cannot 
be accurately forecasted. We continue to evaluate acquisition opportunities, including transactions involving entities controlled 
by Wexford and Gulfport. 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 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, sale-leaseback transactions, 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, our ability to conduct operations, make capital expenditures and/or complete 
acquisitions that may be favorable to us will be impaired.

million. The minimum amount due in the form of shortfall fees under certain sand purchase agreements was $2 million as of December 31, 
2019. 

g.  Obligations arising from capital improvements/equipment purchases.

Off-Balance Sheet Arrangements

Minimum Purchase Commitments

We have entered into agreements with suppliers that contain minimum purchase obligations. Our failure to purchase the 

minimum amounts specified may require us to pay shortfall fees. However, the minimum quantities set forth in the agreements 
are not in excess of our current expected future requirements.

Capital Spend Commitments

We have entered into agreements with suppliers to acquire capital equipment. These commitments are included in our 

2020 capital budget discussed under the heading “Capital Requirements and Sources of Liquidity.”

Aggregate future minimum payments under these agreements in effect at December 31, 2019 are as follows (in

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated 
financial statements, which have been prepared in accordance with accounting principles generally accepted in the United 
States. Below, we have provided expanded discussion of our more significant accounting policies, estimates and judgments. We 
believe these accounting policies reflect our more significant estimates and assumptions used in preparation of our financial 
statements. See Note 2 of our consolidated financial statements included elsewhere in this annual report for a discussion of 
additional accounting policies and estimates made by management.

Use of Estimates. In preparing the financial statements, our management makes informed judgments and estimates 

that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the 
financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ 
from those estimates. Significant estimates include but are not limited to the Company's sand reserves and their impact on 
calculating depletion expense, allowance for doubtful accounts, asset retirement obligations, reserves for self-insurance, 
depreciation and amortization of property and equipment, business combination valuations, amortization of intangible assets, 
and future cash flows and fair values used to assess recoverability and impairment of long-lived assets, including goodwill. 

Revenue Recognition. On January 1, 2018, we adopted the new revenue guidance under ASC 606, Revenue from 

Contracts with Customers, 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. The adoption of ASC 606 did not have a 
material impact on our consolidated financial statements. The Company's primary revenue streams include infrastructure 
services, pressure pumping services, natural sand proppant services, drilling services and other services, which includes coil 
tubing, pressure control, flowback, cementing, acidizing, equipment rentals, crude oil hauling, full service transportation and 
remote accommodations services.

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). We account 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. 

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, we 
account for pressure pumping services as a single performance obligation satisfied over time. In certain circumstances, 
we supply proppant that is utilized for pressure pumping as part of the agreement with the customer. These pressure 
pumping agreements are accounted for as multiple performance obligations satisfied over time. Jobs for pressure 
pumping services are typically short-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, we have agreed to provide that customer with use of up to 

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. We 
have the right to receive consideration from this customer even if circumstances prevent us from performing work. All 
consideration owed to us 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.

Natural Sand Proppant Services. We sell natural sand proppant through sand supply agreements with our 

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. We recognize 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.

80

Certain of our sand supply agreements contain a minimum volume commitment related to sand purchases 

whereby we charge 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, we have future 
performance obligations to deliver excess volumes of product in subsequent periods. In accordance with ASC 606, if 
the customer fails to meet the minimum volume commitment, we assess whether we expect 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 we expect the customer will make-up deficient volumes in future periods, 
revenue related to shortfall payments is 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. If we do not expect the customer will make-up deficient volumes in future periods, we apply the 
breakage model and revenue related to shortfall payments is recognized when the model indicates the customer's 
inability to take delivery of excess volumes. 

In certain of our sand supply agreements, the customer obtains control of the product when it is loaded into 
rail cars and the customer reimburses us for all freight charges incurred. We have 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, we accrue the related costs of those shipping and handling activities.

Drilling Services. Contract drilling services were 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 were recognized over the days of actual drilling. As a result of market conditions, the 
Company temporarily shutdown its contract land drilling operations in December 2019. 

Other Services. During the periods presented in this report, we also provided coil tubing, pressure control, 

flowback, cementing, acidizing, equipment rentals, crude oil hauling, full service transportation and remote 
accommodations services, which are reported under other services. As a result of market conditions, the Company has 
temporarily shut down its cementing and acidizing operations as well as its flowback operations beginning in July 
2019. Other 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. 

Allowance for Doubtful Accounts. We regularly review receivables and provide for estimated losses through an 

allowance for doubtful accounts. In evaluating the level of established reserves, we make judgments regarding our customers’ 
ability to make required payments, economic events and other factors. As the financial condition of customers change, 
circumstances develop or additional information becomes available, adjustments to the allowance for doubtful accounts may be 
required. In the event we were to determine that a customer may not be able to make required payments, we would increase the 
allowance through a charge to income in the period in which that determination is made. Uncollectable accounts receivable are 
periodically charged against the allowance for doubtful accounts once final determination is made of their uncollectibility.

Depreciation, Depletion, Amortization and Accretion. In order to depreciate and amortize our property and 
equipment, we estimate useful lives, attrition factors and salvage values of these items. Our estimates may be affected by such 
factors as changing market conditions, technological advances in the industries in which we operate or changes in regulations 
governing such industries. Depletion of our mining property and development costs is calculated using the units-of-production 
method on estimated measured tons of in-place reserves.

Impairment of Long-Lived Assets. Long-lived assets are reviewed for impairment when events or changes in 
circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of such assets is 
evaluated by measuring the carrying amount of the assets against the estimated undiscounted future cash flows associated with 
the assets. If such evaluations indicate that the future undiscounted cash flow from the assets is not sufficient to recover the 
carrying value of such assets, the assets are adjusted to their estimated fair values.

Goodwill. Goodwill is tested for impairment annually, or more frequently if events or changes in circumstances 

indicate that goodwill might be impaired. If it is determined that an impairment exists, an impairment charge is recognized for 
the excess of carrying value over implied fair value. The fair value is determined using a combination of the income and market 
approaches. 

81

 
Asset Retirement Obligations. Mine reclamation costs, future remediation costs for inactive mines or other contractual 

site remediation costs are accrued based on management’s best estimate at the end of each period of the costs expected to be 
incurred at a site. Such cost estimates include, where applicable, ongoing care, maintenance and monitoring costs. Changes in 
estimates at inactive mines are reflected in earnings in the period an estimate is revised.

Equity-based Compensation. We measure equity-based payments at fair value on the date of grant and expense the 

value of these equity-based payments in compensation expense over the applicable vesting periods. 

Share-based Compensation. The share-based compensation program consists of restricted stock units granted to 

employees and restricted stock units granted to non-employee directors under the Mammoth Energy Services, Inc. 2016 
Incentive Plan (the “2016 Plan”). We recognize in our financial statements the cost of employee services received in exchange 
for restricted stock based on the fair value of the equity instruments as of the grant date. In general, this value is amortized over 
the vesting period; for grants with a non-substantive service condition, this value is recognized immediately. Amounts are 
recognized in cost of revenues and selling, general, and administrative expenses. 

Income Taxes. Our operations are included in a consolidated federal income tax return and other state returns. 
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the 
financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and 
liabilities are measured using statutory tax rates expected to apply to taxable income in the years in which those temporary 
differences are expected to be recovered or settled. The effect of deferred tax assets and liabilities as a result of a change in tax 
rate is recognized in the period that includes the statutory enactment date. 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.

New Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In February 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 
No. 2016-02 “Leases (Topic 842)” amending the current accounting for leases. Under the new provisions, all lessees will report 
a right of use asset and lease liability on the balance sheet for all leases with a term longer than one year, while maintaining 
substantially similar classifications for financing and operating leases. Lessor accounting remains substantially unchanged with 
the exception that no leases entered into after the effective date will be classified as leveraged leases. ASU 2016-02 is effective 
for fiscal years beginning after December 15, 2018, and interim periods within that fiscal year. We adopted this ASU effective 
January 1, 2019 utilizing the transition method permitted by ASU No. 2018-11 “Leases (Topic 842): Targeted Improvements”, 
issued in August 2018, which permits an entity to recognize a cumulative-effect adjustment to the opening balance of retained 
earnings in the period of adoption with no adjustment made to the comparative periods presented in the consolidated financial 
statements. See Note 15. Leases to our consolidated financial statements included elsewhere in this annual report for the impact 
the adoption of this standard had on our financial statements.

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. We adopted this ASU effective January 1, 2019 
and estimated the fair value of our non-employee awards was approximately $18.9 million as of this date. 

Accounting Pronouncements Not Yet Adopted

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update, or ASU No. 2016-13, 
“Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which amends 
current guidance on reporting credit losses on financial instruments. This ASU requires entities to measure all expected credit 
losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable 
supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on 
financial assets, including trade accounts receivable. We will adopt this standard effective January 1, 2020. This standard will 
not have a material impact on our consolidated financial statements and related disclosures.

Item 7A.  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 $6 million at December 31, 2019. 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 2.0% to 3.5%, based upon a calculation of the excess availability of 
the line as a percentage of the maximum credit limit. At December 31, 2019, we had outstanding borrowings under our 
revolving credit facility of $80 million with a weighted average interest rate of 4.05%. A 1% increase or decrease in the interest 
rate would have increased or decreased our interest expense by approximately $1 million per year. We do not currently hedge 
our interest rate exposure.

Foreign Currency Risk

Our energy services business 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 December 31, 2019, we had $4 million of cash in Canadian accounts. A 10% increase in the strength of the Canadian 
dollar versus the U.S. dollar would have resulted in a decrease in pre-tax income of approximately $0.04 million as of 
December 31, 2019. Conversely, a corresponding decrease in the strength of the Canadian dollar would have resulted in a 
comparable increase 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 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 and Alberta, Canada. For the years ended December 31, 2019, 2018 and 2017, we generated 
approximately 43%, 17% and 42%, respectively, of our revenue from our operations in Ohio, Wisconsin, Minnesota, North 
Dakota, Pennsylvania, West Virginia and Canada where weather conditions may be severe. 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 

83

 
 
 
 
 
 
 
adverse effect on our financial condition and results of operations. Our operations in Oklahoma and Texas are generally not 
affected by seasonal weather conditions.

Inflation

Inflation in the United States has been relatively low in recent years and did not have a material impact on our results 
of operations for the years ended December 31, 2019, 2018 or 2017. Although the impact of inflation has been insignificant in 
recent years, it is still a factor in the United States economy and we tend to experience inflationary pressure on the cost of 
oilfield services and equipment as increasing oil and gas prices increase drilling activity in our areas of operations.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable. 

Item 9A. 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 15d-15(e) 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 December 31, 2019, 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 December 31, 2019, our 
disclosure controls and procedures are effective.

Changes in Internal Controls 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 December 31, 2019 that has materially affected, or is 
reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control Over Financial Reporting and Attestation Report of the Registered 
Public Accounting Firm

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as 

defined in Rule 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended. Our internal control over 
financial reporting is a process designed under the supervision of the Company’s Chief Executive Officer and Chief Financial 
Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial 
statements for external purposes in accordance with generally accepted accounting principles. 

As of December 31, 2019, management conducted an evaluation of the effectiveness of our internal control over 

financial reporting based on the framework in the 2013 Internal Control-Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. Based on its evaluation, management did not identify any material 
weaknesses in our internal control over financial reporting and determined that we maintained effective internal control over 
financial reporting as of December 31, 2019. 

84

 
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Grant Thornton LLP, the independent registered public accounting firm that audited our financial statements for the 

year ended December 31, 2019 included with this Annual Report on Form 10-K, has also audited the effectiveness of our 
internal control over financial reporting as of December 31, 2019, as stated in their accompanying report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders 

Mammoth Energy Services, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of Mammoth Energy Services, Inc. (a Delaware corporation) and 
subsidiaries (the “Company”) as of December 31, 2019, based on criteria established in the 2013 Internal Control-Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the 
Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, 
based on criteria established in the 2013 Internal Control-Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2019, and our 
report dated February 28, 2020 expressed an unqualified opinion on those financial statements.

Basis for opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s 
Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s 
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit 
provides a reasonable basis for our opinion.

Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PART III. 

Information required by Item 10 of Part III is incorporated herein by reference to the definitive Proxy Statement to be 
filed by us pursuant to Regulation 14A of the General Rules and Regulations under the Securities Exchange Act of 1934 within 
120 days after the close of the year ended December 31, 2019.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders 
Mammoth Energy Services, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Mammoth Energy Services, Inc. (a Delaware corporation) 
and subsidiaries (the “Company”) as of December 31, 2019 and 2018, the related consolidated statements of comprehensive 
income (loss), changes in equity, and cash flows for each of the three years in the period ended December 31, 2019, and the 
related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations 
and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with accounting principles 
generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in 
the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (“COSO”), and our report dated February 28, 2020 expressed an unqualified opinion.

Change in Accounting Principle
As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for leases 
in 2019 due to the adoption of Accounting Standards Update No. 2016-02, Leases (Topic 842).

Basis for opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our audits also 
included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ GRANT THORNTON LLP

We have served as the Company’s auditor since 2012.

1.   Organization and Basis of Presentation 

The accompanying consolidated financial statements were prepared in accordance with the rules and regulations of the 
Securities and Exchange Commission, and reflect all adjustments, which in the opinion of management are necessary for 
the fair presentation of the results. 

Mammoth Energy Services, Inc. (“Mammoth Inc.” or the “Company”), 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 Inc.'s infrastructure division provides construction, upgrade, maintenance and repair services to

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.  

Net proceeds to Mammoth Inc. from its sale of 7,500,000 shares of common stock were approximately $103.1 million.  
On the closing date of the IPO, Mammoth Inc. repaid all outstanding borrowings under its revolving credit facility and 
used the remaining net proceeds for general corporate purposes, including the acquisition of additional equipment and 
complementary businesses that enhanced its existing service offerings, broadened its service offerings and expanded its 
customer relationships.

On June 5, 2017, the Company completed the acquisition of (1) Sturgeon, a Delaware limited liability company, which 
included the acquisition of Sturgeon's wholly-owned subsidiaries Taylor Frac, a Wisconsin limited liability company, 
Taylor RE, a Wisconsin limited liability company, and South River, a Wisconsin limited liability company, (2) SR Energy, 
a Delaware limited liability company; and (3) Cementing, a Delaware limited liability company (together with SR Energy, 
the “Stingray Acquisition”) in exchange for the issuance by Mammoth Inc. of an aggregate of 7,000,000 shares of its 
common stock. Prior to its acquisition of Sturgeon, the Company and Sturgeon were under common control and it is 
required under accounting principles generally accepted in the Unites States of America (“GAAP”) to account for this 
common control acquisition in a manner similar to the pooling of interest method of accounting. Therefore, the 
Company's historical financial information 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 for additional disclosure regarding the acquisition of Sturgeon.

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 December 31, 2019 and December 31, 2018, Wexford, Gulfport and Rhino beneficially owned the following shares of 
outstanding common stock of Mammoth Inc.:

The Company's infrastructure services include construction, upgrade, maintenance and repair services to the electrical 
infrastructure industry as well as repair and restoration services in response to storms and other disasters. 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 distribution and production of 
natural sand proppant that is used primarily for hydraulic fracturing in the oil and gas industry. The Company's 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 as well as rig moving services. The Company also provides other services, including coil tubing, 
equipment rentals, crude oil hauling, full service transportation and remote accommodations.

All of the Company’s operations are in North America. During certain of the periods presented in this report, the 
Company provided its infrastructure services primarily in the northeast, southwest and midwest portions of the United 
States and in Puerto Rico. The Company’s infrastructure business depends on infrastructure spending on maintenance,

upgrade, expansion and repair and restoration. Any prolonged decrease in spending by electric utility companies, delays 
or reductions in government appropriations or the failure of customers to pay their receivables could have a material 
adverse effect on the Company’s results of operations and financial condition. 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'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. 

2. 

Summary of Significant Accounting Policies 

Principles of Consolidation
The accompanying consolidated financial statements are prepared in accordance with GAAP and include the accounts of 
the Company and its subsidiaries and the variable interest entities (“VIE”) for which the Company is the primary 
beneficiary. All material intercompany accounts and transactions between the entities within the Company have been 
eliminated.

Variable Interest Entities
The Company consolidates a VIE when it is determined to be the primary beneficiary, which is the party that has both (i) 
the power to direct the activities that most significantly impact the VIE's economic performance and (ii) through its 
interests in the VIE, the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be 
significant to the VIE. See Note 12 for more information on the Company's VIEs. 

Use of Estimates  
The preparation of financial statements in conformity with GAAP requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at 
the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates. Significant estimates include, but are not limited to, the Company's sand 
reserves and their impact on calculating depletion expense, allowance for doubtful accounts, asset retirement obligations, 
reserves for self-insurance, depreciation and amortization of property and equipment, business combination valuations, 
amortization of intangible assets and future cash flows, fair values used to assess recoverability and impairment of long-
lived assets, including goodwill and estimates of income taxes. 

Reclassifications 
Certain reclassifications have been made to prior period amounts to conform to the current period financial statement 
presentation. 

Cash and Cash Equivalents
All highly liquid investments with an original maturity of three months or less are considered cash equivalents. The 
Company maintains its cash accounts in financial institutions that are insured by the Federal Deposit Insurance 
Corporation, with the exception of cash held by Sand Tiger in a Canadian financial institution. At December 31, 2019, we 
had $3.5 million, in Canadian dollars, of cash in Canadian accounts. Cash balances from time to time may exceed the 
insured amounts; however, the Company has not experienced any losses in such accounts and does not believe it is 
exposed to any significant credit risks on such accounts.

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 the 
continental United States in which the Company operates provide for a mineral lien or 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. Interest on delinquent accounts receivable is recognized in other income when 
chargeable and collectability is reasonably assured.

During certain of the periods presented, the Company provided infrastructure services in Puerto Rico under master 
services agreements entered into by Cobra, one of the Company's subsidiaries, with the Puerto Rico Electric Power 
Authority (“PREPA”) to perform repairs to PREPA’s electrical grid as a result of Hurricane Maria. During the year ended

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2019, the Company charged interest on delinquent accounts receivable pursuant to the terms of its 
agreements with PREPA totaling $42.0 million. These amounts are included in other, net on the consolidated statement of 
comprehensive (loss) income. 

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 conditions of customers change, 
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. 
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 final determination is made of their uncollectability.

Following is a roll forward of the allowance for doubtful accounts for the years ended December 31, 2019, 2018 and 2017

At December 31, 2017, the Company reviewed receivables due from PREPA and made specific reserves consistent with 
Company policy which resulted in additions to allowance for doubtful accounts totaling $16.0 million. During the year 
ended December 31, 2018, the Company received payment from PREPA for the amount reserved at December 31, 2017. 
As a result, the Company reversed the 2017 additions to the allowance for doubtful accounts from PREPA in 2018. 

Additionally, the Company has made specific reserves consistent with Company policy which resulted in additions to 
allowance for doubtful accounts totaling $1.4 million, $1.4 million and $0.2 million, respectively, for the years ended 
December 31, 2019, 2018 and 2017. The Company will continue to pursue collection until such time as final 
determination is made consistent with Company policy.  

As of December 31, 2019, PREPA owed the Company approximately $227.0 million for services performed, excluding 
$42.0 million of interest charged on these delinquent balances as of December 31, 2019. The Company believes these 
receivables are collectible. PREPA, however, is currently subject to bankruptcy proceedings, which were filed in July 
2017 and are currently pending in the U.S. District Court for the District of Puerto Rico. As a result, PREPA's ability to 
meet its payment obligations is largely dependent upon funding from the Federal Emergency Management Agency or 
other sources. On September 30, 2019, the Company filed a motion with the U.S. District Court for the District of Puerto 
Rico seeking recovery of the amounts owed to the Company by PREPA. PREPA filed a motion to stay the Company's 
motion on the ground that the ongoing criminal proceedings described in Note 20 below against the former president of 
Cobra and two other individuals may affect the recovery of those amounts. On October 17, 2019, the court granted 
PREPA’s request to stay the Company's motion and, on February 3, 2020, extended the stay until a status conference to be 
held on June 17, 2020. In the event PREPA (i) does not have or does not obtain the funds necessary to satisfy its 
obligations to Cobra under the contracts, (ii) obtains the necessary funds but refuses to pay the amounts owed to the 
Company or (iii) otherwise does not pay amounts owed to the Company for services performed, the receivable may not be 
collectible.

Inventory 
Inventory consists of raw sand and processed sand available for sale, raw materials, chemicals and other products sold as 
a bi-product of completion and production operations and supplies used in performing services. Inventory is stated at the 
lower of cost or market (net realizable value) on an average cost basis. The Company assesses the valuation of its 
inventories based upon specific usage, future utility, obsolescence and other factors. 

Inventory manufactured at the Company’s sand production facilities includes direct excavation costs, processing costs and 
overhead allocation. Stockpile tonnages are calculated by measuring the number of tons added and removed from the 
stockpile. Costs are calculated on a per ton basis and are applied to the stockpiles based on the number of tons in the 
stockpile. Inventory transported for sale at the Company’s terminal facility includes the cost of purchased or 
manufactured sand, plus transportation related charges.

Coil tubing strings of various widths, diameters and lengths are included in inventory. The strings are used in providing 
specialized services to customers who are primarily operators of oil or gas wells and are used at various rates based on 
factors such as well conditions (i.e. pressure and friction), vertical and horizontal length of the well, running speed of the 
string in the well and total running feet accumulated to the string. The Company obtains usage information from data 
acquisition software and other established assessment methods and attempts to amortize the strings over their estimated 
useful life. In no event will a string be amortized over a period longer than 12 months. Amortization of coil strings is 
included in services cost of revenue in the consolidated statements of comprehensive (loss) income and totaled $1.6 
million, $2.2 million and $2.9 million for the years ended December 31, 2019, 2018 and 2017, respectively. 

See Note 5 for additional disclosure related to inventory.

Prepaid Expenses
Prepaid expenses primarily consist of insurance costs and rail car freight and lease expense. These costs are expensed over 
the periods that they benefit.

Property and Equipment 
Property and equipment, including renewals and betterments, are capitalized and stated at cost, while maintenance and 
repairs that do not increase the capacity, improve the efficiency or safety, or improve or extend the useful life are charged 
to operations as incurred. Disposals are removed at cost, less accumulated depreciation, and any resulting gain or loss is 
recorded in operations. Depreciation is calculated using the straight-line method over the shorter of the estimated useful 
life, or the remaining lease term, as applicable. Depreciation does not begin until property and equipment is placed in 
service. Once placed in service, depreciation on property and equipment continues while being repaired, refurbished, or 
between periods of deployment. 

Sand Reserves
Sand reserve costs include engineering, mineralogical studies and other related costs to develop the mine, the removal of 
overburden to initially expose the mineral and building access ways. Exploration costs are expensed as incurred and 
classified as product cost of revenue. Capitalization of mine development project costs begins once the deposit is 
classified as proven and probable reserves. Drilling and related costs are capitalized for deposits where proven and 
probable reserves exist and the activities are directed at obtaining additional information on the deposit or converting non-
reserve minerals to proven and probable reserves and the benefit is to be realized over a period greater than one year. 
Mining property and development costs are amortized using the units-of-production method on estimated measured tons 
in in-place reserves. The impact of revisions to reserve estimates is recognized on a prospective basis.

Long-Lived Assets 
The Company reviews long-lived assets for recoverability in accordance with the provisions of Financial Accounting 
Standards Board (“FASB”) Accounting Standard Codification (“ASC”) 360, Impairment or Disposal of Long-Lived 
Assets, which requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances 
indicate that the carrying amount of the assets may not be recoverable. Recoverability of assets is measured by comparing 
the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. These 
evaluations for impairment are significantly impacted by estimates of revenues, costs and expenses and other factors. If 
long-lived assets are considered to be impaired, the impairment to be recognized is measured by the amount in which the 
carrying amount of the assets exceeds the fair value of the assets. See Note 7 for additional disclosure related to 
impairment of long-lived assets.

F-11

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Goodwill
Goodwill is tested for impairment annually, or more frequently if events or changes in circumstances indicate that 
goodwill might be impaired. If it is determined that an impairment exists, an impairment charge is recognized for the 
excess of carrying value over implied fair value. The fair value is determined using a combination of the income and 
market approaches. See Notes 7 and 8 for additional disclosure related to goodwill.

Other Non-Current Assets
Other non-current assets primarily consist of deferred financing costs on our credit facility (see Note 11), sales tax 
receivables and our equity method investment (see Note 9). Investments are accounted for under the equity method in 
circumstances where the Company has the ability to exercise significant influence over the operating and investing 
policies of the investee, but does not have control. Under the equity method, the Company recognizes its share of the 
investee's earnings in its consolidated statements of comprehensive (loss) income. Investments are evaluated for 
impairment and a charge to earnings is recognized when any identified impairment is determined to be other than 
temporary.  

Asset Retirement Obligations
Mine reclamation costs, future remediation costs for inactive mines and other contractual site remediation costs are 
accrued based on management’s best estimate at the end of each period of the costs expected to be incurred at a site. Such 
cost estimates include, where applicable, ongoing care, maintenance and monitoring costs. Changes in estimates are 
reflected in earnings in the period an estimate is revised.

Business Combinations
The Company accounts for its business acquisitions under the acquisition method of accounting as indicated in FASB 
ASC 805, Business Combinations, which requires the acquiring entity in a business combination to recognize the fair 
value of all assets acquired, liabilities assumed and any noncontrolling interest in the acquiree and establishes the 
acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities 
assumed in business combinations, including contingent assets and liabilities and noncontrolling interest in the acquiree, 
based on fair value estimates as of the date of acquisition. In accordance with FASB ASC 805, the Company recognizes 
and measures goodwill, if any, as of the acquisition date, as the excess of the fair value of the consideration paid over the 
fair value of the identified net assets acquired.

When the Company acquires a business from an entity under common control, whereby the companies are ultimately 
controlled by the same party or parties both before and after the transaction, it is treated for accounting purposes in a 
manner similar to the pooling of interest method of accounting. The assets and liabilities are recorded at the transferring 
entity’s historical cost instead of reflecting the fair market value of assets and liabilities.

Amortizable Intangible Assets 
Intangible assets subject to amortization include customer relationships and trade names. Customer relationships are 
amortized based on an estimated attrition factor and trade names are amortized over their estimated useful lives. See 
Notes 7 and 8 for additional disclosure related to intangible assets. 

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, trade payables and receivables and payables from related parties approximates fair value because of the short-

F-12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
term nature of the instruments. The fair value of long-term debt approximates its carrying value because the cost of 
borrowing fluctuates based upon market conditions. 

Revenue Recognition 
On January 1, 2018, the Company adopted Accounting Standards Update (“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. See Note 3 for additional 
discussion of the Company's revenue. 

The timing of revenue recognition may differ from contract billing or payment schedules, resulting in revenues that have 
been earned but not billed (“unbilled revenue”) or amounts that have been billed, but not earned (“deferred revenue”). The 
Company had $42.1 million and $56.2 million, respectively, of unbilled revenue included in accounts receivable, net in 
the consolidated balance sheets at December 31, 2019 and 2018. The Company had $1.3 million and $4.1 million, 
respectively, of unbilled revenue included in receivables from related parties in the consolidated balance sheets at 
December 31, 2019 and 2018. The Company had $7.2 million and $4.3 million, respectively, of deferred revenue included 
in accrued expenses and other current liabilities in the consolidated balance sheets at December 31, 2019 and 2018. 

Earnings (Loss) per Share
Earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of outstanding 
shares. See Note 16.

Equity-based Compensation
The Company measures equity-based payments at fair value on the date of grant and expenses the value of these equity-
based payments in compensation expense over the applicable vesting periods. See Note 17. 

Stock-based Compensation
The Company's stock-based compensation program consists of restricted stock units granted to employees and restricted 
stock units granted to non-employee directors under the Mammoth Energy Services, Inc. 2016 Incentive Plan (the “2016 
Plan”). The Company recognizes in its financial statements the cost of employee services received in exchange for 
restricted stock based on the fair value of the equity instruments as of the grant date. In general, this value is amortized 
over the vesting period; for grants with a non-substantive service condition, this value is recognized immediately. 
Amounts are recognized in cost of revenue and selling, general and administrative expenses. See Note 18. 

Income Taxes
The Company's operations are included in a consolidated federal income tax return and other state returns. Accordingly, 
the Company has recognized deferred tax assets and liabilities for the future tax consequences attributable to differences 
between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases for all our 
subsidiaries as if each entity were a corporation, regardless of its actual characterization for U.S. federal income tax 
purposes. 

Under FASB ASC 740, Income Taxes, deferred tax assets and liabilities are recognized for the future tax consequences 
attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their 
respective tax bases. Deferred tax assets and liabilities are measured using statutory tax rates expected to apply to taxable 
income in the years in which those temporary differences are expected to be recovered or settled. The effect of deferred 
tax assets and liabilities as a result of a change in tax rate are recognized in the period that includes the statutory 
enactment date. 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. Certain income from our infrastructure services segment and income from our remote 
accommodations business is subject to foreign income taxes, and such taxes are provided in the financial statements 
pursuant to FASB ASC 740. 

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act significantly 
changed US corporate income tax laws by, among other things, reducing the US corporate income tax rate from 35% to 
21% starting in 2018 and creating a territorial tax system with a one-time mandatory tax on previously deferred foreign 
earnings of US subsidiaries. As a result, the Company recorded a one-time reduction to income tax expense of $31.0 
million during the year ended December 31, 2017, which is included in provision for income taxes in the consolidated 
statements of comprehensive income (loss). See Note 14 for further information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 years ended December 31, 2019 and 2018, no uncertain tax positions existed. Penalties 
and interest, if any, are recognized in selling, general and administrative expense and interest expense, respectively. 

Foreign Currency Translation
For foreign operations, assets and liabilities are translated at the period-end exchange rate and income statement items are 
translated at the average exchange rate for the period. Resulting translation adjustments are recorded within accumulated 
other comprehensive income (loss). Assets and liabilities denominated in foreign currencies, if any, are re-measured at the 
balance sheet date. Transaction gains or losses are included as a component of current period earnings.

Environmental Matters
The Company is subject to various federal, state and local laws and regulations relating to the protection of the 
environment. Management has established procedures for the ongoing evaluation of the Company’s operations, to identify 
potential environmental exposures and to comply with regulatory policies and procedures. Environmental expenditures 
that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing 
condition caused by past operations and do not contribute to current or future revenue generation are expensed as 
incurred. Liabilities are recorded when environmental costs are probable and the costs can be reasonably estimated. The 
Company maintains insurance which may cover in whole or in part certain environmental expenditures. As of 
December 31, 2019 and 2018, there were no probable environmental matters.

Other Comprehensive Income (Loss)
Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive 
income (loss) included certain changes in equity that are excluded from net income (loss). Specifically, cumulative foreign 
currency translation adjustments are included in accumulated other comprehensive income (loss). 

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 accounts receivable balances at December 31, 2019 and 2018 and revenues derived for the years

Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 
No. 2016-02 “Leases (Topic 842)” amending the current accounting for leases. Under the new provisions, all lessees will 
report a right of use asset and lease liability on the balance sheet for all leases with a term longer than one year, while 
maintaining substantially similar classifications for financing and operating leases. Lessor accounting remains 
substantially unchanged with the exception that no leases entered into after the effective date will be classified as 
leveraged leases. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within 
that fiscal year. The Company adopted this ASU effective January 1, 2019 utilizing the transition method permitted by 
ASU No. 2018-11 “Leases (Topic 842): Targeted Improvements”, issued in August 2018, which permits an entity to 
recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption with no 
adjustment made to the comparative periods presented in the consolidated financial statements. See Note 15 for the impact 
the adoption of this standard had on the Company's financial statements.

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. The Company adopted this ASU 
effective January 1, 2019 and estimates the fair value of its non-employee awards (see Note 17) was approximately $18.9 
million as of this date.

Accounting Pronouncements Not Yet Adopted
In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of 
Credit Losses on Financial Instruments,” which amends current guidance on reporting credit losses on financial 
instruments. This ASU requires entities to measure all expected credit losses for financial instruments held at the reporting 
date based on historical experience, current conditions and reasonable supportable forecasts. This replaces the existing 
incurred loss model and is applicable to the measurement of credit losses on financial assets, including trade accounts 
receivable. The Company will adopt this standard effective January 1, 2020. This standard will not have a material impact 
on the Company’s consolidated financial statements and related disclosures. 

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 infrastructure services, pressure pumping services, natural sand 
proppant services, drilling services and other services, which includes coil tubing, pressure control, flowback, cementing, 
acidizing, equipment rentals, full service transportations, crude oil hauling and remote accommodations services. See 
Note 21 for the Company's revenue disaggregated by type. 

F-15

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. 

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-
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 up to 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.

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 periods. 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 December 31, 2019 and 2018, the Company had deferred revenue totaling $7.2 
million and $4.2 million, respectively, related to shortfall payments. These amount is included in accrued expenses and 
other current liabilities on the 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 years ended 
December 31, 2019 and 2018, the Company recognized revenue totaling $2.8 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.

Drilling Services
Contract drilling services were 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 were 
recognized over the days of actual drilling. As a result of market conditions, the Company temporarily shut down its 
contract land drilling operations in December 2019. 

Other Services
During the periods presented, the Company also provided coil tubing, pressure control, flowback, cementing, acidizing, 
equipment rentals, crude oil hauling, full service transportation and remote accommodations services, which are reported 
under other services. As a result of market conditions, the Company temporarily shut down its cementing and acidizing 
operations as well as its flowback operations during the third quarter of 2019. The Company's other services are typically

4.  Acquisitions 

Acquisition of Air Rescue Systems and Brim Equipment Assets

On December 21, 2018, Cobra Aviation, a variable interest entity of the Company, completed a series of transactions that 
provided for an expansion of its aviation service business. These transactions include (i) the acquisition of all outstanding 
equity interests in ARS, (ii) the purchase of two commercial helicopters, spare parts, support equipment and aircraft 
documents from Brim Equipment Leasing, Inc. (“Brim Equipment”) (the “Brim Equipment Assets”) and (iii) the 
formation of a joint venture between Cobra Aviation and Wexford Partners Investment Co. LLC (“Wexford Investment”), 
a related party, under the name of Brim Acquisitions LLC (“Brim Acquisitions”), which acquired all outstanding equity 
interest in Brim Equipment. Cobra Aviation owns a 49% economic interest and Wexford Investment owns a 51% 
economic interest in Brim Acquisitions, and each member contributed its pro rata portion of Brim Acquisitions initial 
capital of $2.0 million. 

F-17

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The acquisition of ARS qualifies under FASB ASC 805, Business Combinations, as a business combination. The purchase 
of the Brim Equipment Assets was negotiated and funded as part of the acquisition. Therefore, the purchase of the Brim 
Equipment Assets also qualifies as a business combination under ASC 805. Cobra Aviation is able to exercise significant 
influence over Brim Acquisitions, but is a minority owner and does not have controlling financial interest. As a result, 
Cobra Aviation's investment in Brim Acquisitions is accounted for as an equity method investment under FASB ASC 323, 
Investments-Equity Method and Joint Ventures. See Note 9 for additional information on our investment in Brim 
Acquisitions. 

Total consideration paid for ARS and the Brim Equipment Assets was $2.7 million and $4.2 million, respectively. The 
Company used cash on hand to fund the acquisitions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 all outstanding 
membership interests, through its wholly-owned subsidiary Mammoth LLC, 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 Inc. 
issued 5,607,452 shares of its common stock, par value $0.01 per share, for all outstanding equity interests in Sturgeon. 
Based upon a closing price of Mammoth Inc.'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 has been recast to combine the consolidated 
statements of comprehensive income (loss) and the consolidated balance sheets of the Company for all periods 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. 

The Company recognized $1.3 million of transaction related costs during the year ended December 31, 2017 related to 
this acquisition. 

Acquisition of Chieftain

On March 27, 2017, as amended as of May 24, 2017, the Company entered into a purchase agreement with the Chieftain 
Sellers, following the Company's successful bid in a bankruptcy court auction for substantially all of the assets of the 
Chieftain Sellers (the “Chieftain Assets”). The Chieftain acquisition closed on May 26, 2017. The Company funded the 
purchase price for the Chieftain Assets with cash on hand and borrowings under its revolving credit facility. The Chieftain 
Assets are held by the Company's wholly owned subsidiary Piranha and are included in the Company's natural sand 
proppant services segment. The Chieftain acquisition added sand reserves, increased our production capacity and provided 
access to the Union Pacific railroad, which affords access to both the Mid-Continent and Permian basins in support of the 
Company’s pressure pumping services.

On March 20, 2017, and as amended on May 12, 2017, the Company entered into two definitive contribution agreements, 
one such agreement with MEH Sub, Wexford Offshore Stingray Energy Corp., Gulfport and Mammoth LLC and the other

outstanding membership interests, through its wholly-owned subsidiary Mammoth LLC, in Cementing and SR Energy 
(the “2017 Stingray Acquisition”). The addition of their water transfer, equipment rentals and cementing services further 
expanded and vertically integrated the Company’s service offerings. 

The 2017 Stingray Acquisition closed on June 5, 2017. Pursuant to the Stingray Contribution Agreements, Mammoth Inc. 
issued 1,392,548 shares of its common stock, par value $0.01 per share, for all outstanding equity interests in SR Energy

Impairment of Goodwill
The Company performed its annual assessment of goodwill during the fourth quarter of 2019 and determined that the 
carrying value of goodwill for certain of its entities was greater than their fair values. As a result, the Company impaired 
goodwill associated with Stingray Pressure Pumping, SR Energy, Taylor Frac and Cobra Aviation, resulting in a $30.5 
million impairment charge in 2019. To determine fair value at December 31, 2019, the Company used a combination of the 
income and market approaches. The income approach estimates the fair value based on anticipated cash flows that are 
discounted using a weighted average cost of capital. The market approach estimates the fair value using comparative 
multiples, which involves significant judgment in the selection of the appropriate peer group companies and valuation 
multiples. Additionally, during the third quarter of 2019, the Company temporarily shut down its cementing and acidizing 
operations. As a result, the Company recognized goodwill impairment expense of $3.2 million associated with Cementing 
and Stingray Cementing and Acidizing. The fair value was measured using an income approach.

During the year ended December 31, 2018, the Company moved Cementing's equipment from the Utica Shale to the 
Permian Basin. As a result, the Company recognized impairment on Cementing's goodwill totaling $3.2 million. The fair 
value was measured using an income approach.

million and $3.8 million, respectively, related to drilling rig assets and $3.6 million, $0.3 million and $0.3 million, 
respectively, related to other property, plant and equipment. These assets were deemed impaired based on future expected 
cash flows of the equipment. The Company measured the fair values of its drilling rig assets at December 31, 2018 and 
2017 and other property, plant and equipment at December 31, 2019, 2018 and 2017 using significant unobservable inputs 
(Level 3) based on an income approach. The Company measured the fair value of its drilling rig assets at December 31, 
2019 using significant unobservable inputs (Level 3) based on a market approach. 

The Company determined the fair value of WTL's non-contractual customer relationships was less than their carrying 
value, resulting in impairment expense of $0.8 million during the year ended December 31, 2019. Additionally, during the

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

third quarter of 2019, the Company temporarily shut down its flowback operations, resulting in impairment of non-
contractual customer relationships of $0.1 million. 

During the year ended December 31, 2018, the Company moved Cementing's equipment from the Utica shale to the 
Permian basin. As a result, the Company recognized impairment on Cementing's intangible assets, including non-
contractual customer relationships and trade name of $1.0 million and $0.2 million, respectively. Additionally, the 
Company recognized impairment of trade name totaling $0.2 million related to the name change of Stingray Logistics to 
Silverback Energy, which is included in the Company's Pressure Pumping segment. 

The assumptions used in the impairment evaluation for long-lived assets are inherently uncertain and require 
management’s judgment. A continued period of low oil and natural gas prices or continued reductions in capital 
expenditures by our customers would likely have an adverse impact on our utilization and the prices that we receive for our 
services. This could result in the recognition of future material impairment charges on the same, or additional, property and 
equipment if future cash flow estimates, based upon information then available to management, indicate that their carrying 
values are not recoverable.

9.  Equity Method Investment

On December 21, 2018, Cobra Aviation and Wexford Investment, a related party, formed a joint venture under the name 
of Brim Acquisitions to acquire all outstanding equity interest in Brim Equipment for a total purchase price of 
approximately $2.0 million. Cobra Aviation owns a 49% economic interest and Wexford Investment owns a 51% 
economic interest in Brim Acquisitions, and each member contributed its pro rata portion of Brim Acquisitions initial 
capital of $2.0 million. Brim Acquisitions, through Brim Equipment, owns one commercial helicopter and leases one 
commercial helicopter for operation, which it uses to provide a variety of services, including short haul, aerial ignition, 
hoist operations, aerial photography, fire suppression, construction services, animal/capture/survey, search and rescue, 
airborne law enforcement, power line construction, precision long line operations, pipeline construction and survey, 
mineral and seismic exploration, and aerial seeding and fertilization.

The Company uses the equity method of accounting to account for its investment in Brim Acquisitions, which had a 
carrying value of approximately $2.6 million and $1.0 million, respectively, at December 31, 2019 and 2018. The 
investment is included in other non-current assets on the consolidated balance sheets. The Company recorded equity 
method adjustments to its investment for its share of Brim Acquisitions' income (loss) of $1.0 million for the year ended 
December 31, 2019 and ($0.02) million for the period between the acquisition date and December 31, 2018, which is 
included in other, net on the consolidated statements of comprehensive (loss) income. The Company made additional 
investments totaling $0.7 million during the year ended December 31, 2019.

premiums ranged from 3.45% to 3.75%. As of December 31, 2018, the applicable interest rate associated with financed 
insurance premiums was 3.45%.

11.  Debt 

Mammoth Credit Facility

On October 19, 2018, Mammoth Inc. 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, as amended and restated (the “revolving credit 
facility”). The revolving credit facility matures on October 19, 2023. Borrowings under the revolving credit facility are 
secured by the assets of Mammoth Inc., inclusive of the subsidiary companies, and are subject to a borrowing base 
calculation prepared monthly. On November 5, 2019, the Company entered into a first amendment to the revolving credit 
facility to amend the interest coverage ratio definition to give accrual treatment to certain cash taxes included in the ratio 
calculation. As a result, certain cash tax payments that were made in 2019 were now treated as if they were made in 2018, 
the year in which the income related to such tax payments was actually received. 

As of December 31, 2019, outstanding borrowings under the revolving credit facility bore interest at a per annum rate 
elected by Mammoth Inc. that was equal to an alternate base rate or LIBOR, in each case plus the applicable margin. As of 
December 31, 2019, the applicable margin ranged 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 the revolving credit facility.

At December 31, 2019, there were outstanding borrowings under the revolving credit facility of $80.0 million and $96.1 
million of available borrowing capacity, after giving effect to $8.7 million of outstanding letters of credit. At 
December 31, 2018, there were no outstanding borrowings under the revolving credit facility and $175.8 million of 
borrowing capacity under the facility, after giving effect to $8.4 million of outstanding letters of credit.

As of December 31, 2019, the revolving credit facility contained 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). As of December 31, 2019 and 2018, the Company was in compliance with its 
covenants under the revolving credit facility. However, the Company believes that its adjusted EBITDA for the trailing 
four fiscal quarters would have resulted in a breach of the maximum leverage ratio and/or the interest coverage ratio as 
early as the end of the first quarter of 2020 if the Company did not receive payments due from PREPA before the end of 
such quarter.  As the Company believes that such payments from PREPA are unlikely to be received by March 31, 2020,  
on February 26, 2020, the Company entered into a second amendment to the revolving credit facility to, among other 
things, (i) amend its financial covenants, as outlined below, (ii) decrease the maximum revolving advance amount from 
$185 million to $130 million, (iii) decrease the amount that the maximum revolving advance can be increased to (the 

F-29

 
 
MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

accordion) from $350 million to $180 million, (iv) increase the applicable margin ranges from 2.00% to 2.50% per annum 
in the case of the alternate base rate and from 3.00% to 3.50% per annum in the case of LIBOR, (v) increase the aggregate 
amount of permitted asset dispositions, and (vi) permit certain sale-leaseback transactions.

The financial covenants under the revolving credit facility were amended as follows:

• 
• 

• 

• 

the minimum interest coverage ratio of 3.0 to 1.0 was eliminated;
the maximum leverage coverage ratio of 4.0 to 1.0 was eliminated for the first two fiscal quarters of 2020 and, 
beginning with the fiscal quarter ended September 30, 2020, changed to 2.5 to 1.0;
beginning with the fiscal quarter ended September 30, 2020, a minimum fixed charge coverage ratio of at least 1.1 to 
1.0 was added; and
from the effective date of February 26, 2020 through September 30, 2020, a minimum excess availability covenant of 
10% of the maximum revolving advance amount was added.

As of February 26, 2020, the Company had $87.4 million in borrowings outstanding under its revolving credit facility, 
leaving an aggregate of $20.6 million of available borrowing capacity under this facility, after giving effect to the recent 
amendment that reduced the maximum revolving advance amount to $130 million. The available borrowing capacity is 
reduced by (i) a minimum excess availability covenant of 10% of the maximum revolving advance amount and (ii) $9.0 
million of outstanding letters of credit.

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. 

12.   Variable Interest Entities

Dire Wolf Energy Services LLC (“Dire Wolf”) and Predator Aviation LLC (“Predator Aviation”), wholly owned 
subsidiaries of the Company, are party to Voting Trust Agreements with TVPX Aircraft Solutions Inc. (the “Voting 
Trustee”). Under the Voting Trust Agreements, Dire Wolf transferred 100% of its membership interest in Cobra Aviation 
and Predator Aviation transferred 100% of its membership in Leopard Aviation LLC (“Leopard') to the respective Voting 
Trustees in exchange for Voting Trust Certificates. Dire Wolf and Predator Aviation retained the obligation to absorb all 
expected returns or losses of Cobra Aviation and Leopard. Prior to the transfer of the membership interest to the Voting 
Trustee, Cobra Aviation was a wholly owned subsidiary of Dire Wolf and Leopard was a wholly owned subsidiary of 
Predator Aviation. Cobra Aviation owns three helicopters and support equipment, 100% of the equity interest in ARS and 
49% of the equity interest in Brim Acquisitions. Leopard owns one helicopter. Dire Wolf and Predator Aviation entered 
into the Voting Trust Agreements in order to meet certain registration requirements.

Dire Wolf's and Predator Aviation's voting rights are not proportional to their respective obligations to absorb expected 
returns or losses of Cobra Aviation and Leopard and all of Cobra Aviation's and Leopard's activities are conducted on 
behalf of Dire Wolf and Predator Aviation, which have disproportionately fewer voting rights; therefore, Cobra Aviation 
and Leopard meet the criteria of a VIE. Cobra Aviation's and Leopard's operational activities are directed by Dire Wolf's 
and Predator Aviation's officers and Dire Wolf and Predator Aviation have the option to terminate the Voting Trust 
Agreements at any time. Therefore, the Company, through Dire Wolf and Predator Aviation, is considered the primary 
beneficiary of the VIEs and consolidates Cobra Aviation and Leopard at December 31, 2019.

The Company's effective tax rate was 13.3% for the year ended December 31, 2019 compared to 39.4% for the year ended 
December 31, 2018 and 4.9% for the year ended December 31, 2017. The decrease in effective tax rate from 2018 to 2019 
is primarily the result of a decline in earnings for the Company's Puerto Rico operations as well as return to provision 
adjustments and goodwill impairment. The increase in effective tax rate from 2017 to 2018 is primarily the result of a tax 
rate change recorded in 2017 related to the Tax Act as discussed below. Additionally, the Company's tax rate was affected 
by the mix of earnings between the U.S. and Puerto Rico, increased foreign tax credits resulting from increased 
profitability in foreign jurisdictions, changes in valuation allowance on excess foreign tax credit carryforwards and 
withholding taxes on foreign source income, as well as other items, such as equity compensation expense and certain non-
deductible expenses. 

On December 22, 2017, the United States enacted the Tax Act. The Tax Act significantly changed U.S. corporate income 
tax laws by, among other things, reducing the U.S. corporate income tax rate from 35% to 21% starting in 2018 and 
creating a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S. 
subsidiaries. Under the accounting rules, companies were required to recognize the effects of changes in tax laws and tax 
rates on deferred tax assets and liabilities in 2017, the period in which the new legislation was enacted. The effects of the 
Tax Act on the Company included (i) remeasurement of deferred taxes and (ii) recognition of liabilities for taxes on 
mandatory deemed repatriation. As a result of the Tax Act, the Company recorded a credit of $31.0 million during the 
fourth quarter of 2017. This amount, which is included in (benefit) provision for income taxes in the consolidated 
statements of comprehensive (loss) income, consists of two components: (i) a $21.3 million credit resulting from the 
remeasurement of the Company's net deferred tax liabilities in the U.S. based on the new lower corporate income tax rate, 
and (ii) a $9.7 million credit related to a reversal of deferred liabilities for unrepatriated foreign earnings. The SEC staff 
issued Staff Accounting Bulletin No. 118 in December 2017, which allowed registrants to record provisional amounts for 
effects of the Tax Act during a one-year measurement period. The Company completed its analysis of the Tax Act during 
the fourth quarter of 2018 and recorded a nominal adjustment to its provisional estimates.

During the years ended December 31, 2019 and 2018, the Company recorded changes in its valuation allowance of $12.0 
million and $36.3 million, respectively, related to excess foreign tax credits that are not expected to be utilized. The 
Company has foreign tax credits carryforwards of $76.1 million as of December 31, 2019.  These credits have a 10 year 
carryforward period and begin to expire in 2028.

The Company maintains a partial valuation allowance related to U.S. foreign tax credit carryforwards, as it cannot 
objectively assert that these deferred tax assets are more likely than not to be realized. All available positive and negative 
evidence was weighed to determine whether a valuation allowance was necessary. The more significant evidential matter 
is the higher foreign tax rate applied to foreign source income in comparison to the U.S. Federal tax rate of 21%. As a 
result, the Company’s has foreign tax credits in excess of the corresponding U.S. income tax liability for which the foreign 
tax credits are allowed as an offset and, therefore, are not likely to be realized.

At December 31, 2019, the Company had federal net operating loss carryforwards of $17.8 million that are not subject to 
expiration, however are limited to 80% of taxable income in any carryforward period.

At December 31, 2019, the Company had undistributed earnings in its Puerto Rico foreign branch. The distribution of 
these undistributed earnings is subject to a withholding tax in Puerto Rico and since the Company intends to make these 
distributions in the future, the withholding tax has been accrued.  

As of December 31, 2019, the Company had no uncertain tax positions or interest and penalties that qualify for either 
recognition or disclosure in the financial statements.

15.  Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which supersedes the requirements set forth in 
ASC 840, Leases. The Company adopted this standard effective January 1, 2019 utilizing the transition method which 
permits an entity to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of 
adoption with no adjustment made to the comparative periods presented in the consolidated financial statements. 
Accordingly, the comparative information as of December 31, 2018 and for the years ended December 31, 2018 and 
2017, have not been adjusted and continues to be reported under the previous lease standard. The new guidance requires 
lessees to report a right of use asset and lease liability on the balance sheet for all leases with a term longer than one 
year, while maintaining substantially similar classifications for financing and operating leases. Lessor accounting 
remains substantially unchanged with the exception that no leases entered into after the effective date will be classified 
as leveraged leases. 

The Company elected the transition practical expedient package whereby an entity was not required to reassess (i) 
whether any expired or existing contracts are or contained leases, (ii) the lease classification for any expired or existing 
leases and (iii) initial direct costs for any existing leases. The adoption of ASC 842 resulted in the recognition of 
approximately $60.0 million of operating lease right-of-use assets and operating lease liabilities on our consolidated 
balance sheet as of January 1, 2019 and did not materially impact our consolidated statement of comprehensive (loss) 
income for the year ended December 31, 2019. 

Lessee Accounting

Beginning January 1, 2019, for all leases with a term in excess of 12 months, the Company recognized a lease liability 
equal to the present value of the lease payments and a right-of-use asset representing its right to use the underlying asset 
for the lease term. For operating leases, lease expense for lease payments is recognized on a straight-line basis over the 
lease term, while finance leases include both an operating expense and an interest expense component. For all leases 
with a term of 12 months or less, the Company elected the practical expedient to not recognize lease assets and liabilities 
and recognizes lease expense for these short-term leases on a straight-line basis over the lease term. 

The Company's operating leases are primarily for rail cars, real estate, equipment and vehicles and its finance leases are 
primarily for machinery and equipment. Generally, the Company does not include renewal or termination options in its 
assessment of the leases unless extension or termination for certain assets is deemed to be reasonably certain. The 
accounting for some of the Company's leases requires significant judgment, which includes determining whether a 
contract contains a lease, determining the incremental borrowing rates to utilize in the net present value calculation of 
lease payments for lease agreements which do not provide an implicit rate and assessing the likelihood of renewal or 
termination options. Lease agreements that contain a lease and non-lease component are generally accounted for as a 
single lease component. 

The rate implicit in the Company's leases is not readily determinable. Therefore, the Company uses its incremental 
borrowing rate based on information available at the commencement date of its leases in determining the present value 
of lease payments. The Company's incremental borrowing rate reflects the estimated rate of interest that it would pay to 
borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic 
environment.

As of December 31, 2018, future minimum payments under noncancellable operating leases were $66.2 million in the 
aggregate, which consisted of the following: $20.2 million in 2019, $16.6 million in 2020, $12.6 million in 2021, $9.3 
million in 2022, $5.0 million in 2023 and $2.5 million thereafter.

Lessor Accounting

Certain of the Company's agreements with its customers for contract land drilling services, aviation services and remote 
accommodation services contain an operating lease component under ASC 842 because (i) there are identified assets, (ii) 
the customer obtains substantially all of the economic benefits of the identified assets throughout the period of use and 
(iii) the customer directs the use of the identified assets throughout the period of use. The Company has elected to apply 
the practical expedient provided to lessors to combine the lease and non-lease components of a contract where the 
revenue recognition pattern is the same and where the lease component, when accounted for separately, would be 
considered an operating lease. The practical expedient also allows a lessor to account for the combined lease and non-
lease components under ASC 606, Revenue from Contracts with Customers, when the non-lease component is the 
predominant element of the combined component. The Company's agreements for its contract land drilling services 
contain a service component in addition to a lease component. The Company has determined the service component is 
greater than the lease component and therefore, reports revenue for its contract land drilling services under ASC 606.

The Company's lease agreements are generally short-term in nature and lease revenue is recognized over time based on a 
monthly, daily or hourly rate basis. The Company does not provide an option for the lessee to purchase the rented assets 
at the end of the lease and the lessees do not provide residual value guarantees on the rented assets. During the year 
ended December 31, 2019, the Company recognized lease revenue, which is included in services revenue - related 
parties and services revenue on the consolidated statements of comprehensive (loss) income, of $1.8 million and $0.6 
million, respectively. 

16.  Dividends and Earnings (Loss) Per Share

Dividends

On July 16, 2018, the Company initiated a quarterly dividend policy. As a result of oilfield market conditions and other 
factors, which include collections from PREPA, the Company's Board of Directors suspended the quarterly cash dividend 
in the third quarter of 2019. The table below summarizes the dividends paid on the Company's common stock.

17.  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).

On November 24, 2014, the awards were modified in conjunction with the contribution of the operating entities to 
Mammoth Inc. 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 Inc.’s majority equity holder.

On the IPO closing date, the unreturned capital balance of Mammoth Inc.'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 year ended December 31, 2018, the 

F-37

 
 
 
 
MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

The Company adopted ASU 2018-07 as of January 1, 2019. This ASU aligns the accounting for non-employee share-
based compensation with the requirements for employee share-based compensation. The standard required non-employee 
awards to be measured at fair value as of the date of adoption. For the Company's Non-Employee Member awards, the 
unrecognized amount, which represents the fair value of the awards as of the date of adoption of ASU 2018-07 was $18.9 
million. 

18.  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 incentive restricted stock, restricted stock unit, 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. Forfeitures are recognized as they occur. 

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

Insurance
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 
December 31, 2019 and 2018, the workers' compensation and automobile liability policies required a deductible per 
occurrence of up to $0.3 million and $0.1 million, respectively. The Company establishes liabilities for the unpaid 
deductible portion of claims incurred based on estimates. As of December 31, 2019 and 2018, the workers' compensation 
and auto liability policies contained an aggregate stop loss of $5.4 million. The Company establishes liabilities for the 
unpaid deductible portion of claims incurred relating to workers’ compensation and auto liability based on estimates. As 
of December 31, 2019 and 2018, accrued claims were $2.9 million and $4.7 million, respectively.

The Company also has insurance coverage for directors and officers liability. As of December 31, 2019 and 2018, the 
directors and officers liability policy had a deductible per occurrence of $1.0 million and an aggregate deductible of $10.0 
million. As of December 31, 2019 and 2018, the Company did not have any accrued claims for directors and officers 
liability.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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, 2019. As of December 31, 2019 and 2018, accrued claims were $3.0 million and $3.2 million, 
respectively. These estimates may change in the near term as actual claims continue to develop. 

Warranty Guarantees
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 December 31, 2019 or 2018 and no expense was 
recognized during the years ended December 31, 2019, 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. 

Bonds
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 December 31, 2019 and 2018, outstanding performance and payment bonds totaled $40.4 million and $22.3 
million, respectively. The estimated cost to complete projects secured by the performance and payment bonds totaled $8.0 
million as of December 31, 2019. As of December 31, 2018, outstanding bid bonds totaled $3.6 million. The Company 
did not have any bid bonds outstanding as of December 31, 2019.

Litigation 
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 business, financial condition, results of operations or cash flows.

On June 19, 2018, Wendco of Puerto Rico Inc. filed a putative class action lawsuit in the Commonwealth of Puerto Rico 
styled 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, et al. The plaintiffs allege that 
the defendants caused power outages in Puerto Rico while performing restoration work on Puerto Rico’s electrical 
network following Hurricanes Irma and Maria in 2017, thereby interrupting commercial activities and causing economic 
loss.  The Company believes these claims are without merit and will vigorously defend the action. However, at this time, 
the Company is not able to predict the outcome of this lawsuit or whether it will have a material impact on the Company's 
business, financial condition, results of operations or cash flows.

On various dates in 2018 and 2019, Cobra was served with four lawsuits from municipalities in Puerto Rico alleging 
failure to pay municipal license and construction excise taxes. In 2020, five additional municipalities in Puerto Rico filed 
lawsuits against Cobra making substantially similar allegations. The Government of Puerto Rico's Central Recovery and 
Reconstruction Office (“COR3”) has noted the unique nature of work executed by entities such as Cobra in Puerto Rico 
and that taxes, such as those in these matters, may be eligible for reimbursement by the government. Further, COR3 
indicated that it is working to develop a solution that will result in payment of taxes owed to the municipalities without 
placing an undue burden on entities such as Cobra. The Company continues to work with COR3 to resolve these matters. 
However, at this time, the Company is not able to predict the outcome of these matters or whether they will have a 
material impact on the Company's business, financial condition, results of operations or cash flows.

On March 20, 2019, EJ LeJeune, a former employee of ESPADA Logistics and Security Group, LLC and ESPADA 
Caribbean LLC (together, “ESPADA”) filed a collective and class action complaint in LeJeune v. Mammoth Energy 
F-42

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Services, Inc. d/b/a Cobra Energy & ESPADA Logistics and Security Group, LLC, No. 5:19-cv-00286-DAE, in the 
Western District of Texas. On August 5, 2019, the court granted the plaintiff’s motion for leave to amend his complaint, 
dismissing Mammoth Energy Services, Inc. as a defendant, adding Cobra Acquisitions LLC (“Cobra”) as a defendant, and 
adding ESPADA Caribbean LLC and two officers of ESPADA-James Jorrie and Jennifer Gay Jorrie-as defendants. The 
amended complaint alleges that the defendants jointly employed the plaintiff and all similarly situated workers and failed 
to pay them overtime as required by the Fair Labor Standards Act and Puerto Rico law. The complaint also alleges the 
following violations of Puerto Rico law: illegal deductions from workers’ wages, failure to timely pay all wages owed, 
failure to pay a required severance when terminating workers without just cause, failure to pay for all hours worked, 
failure to provide required meal periods and failure to pay a statutorily required bonus to eligible workers. The parties 
have agreed to stay the case until May 31, 2020 in order to conduct a mediation. Mr. LeJeune seeks to represent a class of 
workers allegedly employed by one or both defendants and paid a flat amount for each day worked regardless of how 
many hours were worked. The complaint seeks back wages, including overtime wages owed, liquidated damages equal to 
the overtime wages owed, attorneys’ fees, costs, and pre- and post-judgment interest. Cobra denies that it employed Mr. 
LeJeune and the putative class members and intends to enforce the indemnification obligations owed to it by ESPADA. At 
this time, the Company is not able to predict the outcome of these proceedings or whether they will have a material impact 
on the Company’s business, financial condition, results of operations or cash flows.

On April 16, 2019, a putative class and collective action lawsuit was filed in the U.S. District Court for the District of 
Puerto Rico, styled Christopher Williams, individually and on behalf of all others similarly situated v. Higher Power 
Electrical, LLC, Cobra Acquisitions LLC, and Cobra Energy LLC. On June 24, 2019, the complaint was amended to 
replace Mr. Williams with Matthew Zeisset as the named plaintiff. The plaintiffs allege that the Company failed to pay 
overtime wages to a class of workers in compliance with the Fair Labor Standards Act and Puerto Rico law. On July 8, 
2019, the defendants moved to dismiss the plaintiffs’ claims and compel them to arbitration on an individual basis. On 
August 21, 2019, upon request of the parties, the court stayed proceedings in the lawsuit pending completion of the 
arbitration proceedings involving Mr. Zeisset and all opt-in plaintiffs. The plaintiff and additional claimants subsequently 
initiated individual arbitration proceedings which remain pending. In a similar matter, in April 2019, the Company 
received a demand for arbitration from seven individual claimants alleging the Company failed to pay overtime in 
violation of the Fair Labor Standards Act and Puerto Rico law. Other claimants have subsequently initiated individual 
arbitration proceedings as well. All complainants and the respondents have paid the filing fees necessary to initiate the 
arbitrations. The parties are currently waiting for arbitrators to be assigned to these matters. At this time, the Company is 
not able to predict the outcome of these proceedings or whether they will have a material impact on the Company’s 
business, financial condition, results of operations or cash flows.

In June 2019 and August 2019, the Company was served with three class action lawsuits filed in the Western District of 
Oklahoma. On September 13, 2019, the court consolidated the three lawsuits under the case caption In re Mammoth 
Energy Services, Inc. Securities Litigation. On November 12, 2019, the plaintiffs filed their first amended complaint 
against Mammoth Energy Services, Inc., Arty Straehla, and Mark Layton. Pursuant to their first amended complaint, the 
plaintiffs brought a consolidated putative federal securities class action on behalf of all investors who purchased or 
otherwise acquired Mammoth Energy Services, Inc. common stock between October 19, 2017, and June 5, 2019, 
inclusive. On January 10, 2020, the defendants filed their motion to dismiss the first amended complaint. The Company 
believes the plaintiffs’ claims are without merit and will vigorously defend the action. However, at this time, the Company 
is not able to predict the outcome of this lawsuit or whether it will have a material impact on the Company's business, 
financial condition, results of operations or cash flows.

In September 2019, four derivative lawsuits were filed, two in the Western District of Oklahoma and two in the District of 
Delaware, purportedly on behalf of the Company and against its officers and directors. In October 2019, the plaintiffs in 
the two Oklahoma actions voluntarily dismissed their respective cases, with one plaintiff refiling his action in the District 
of Delaware. On September 13, 2019, the Delaware court consolidated the three actions under the case caption In re 
Mammoth Energy Services, Inc. Consolidated Shareholder Litigation. On January 17, 2020, the plaintiffs filed their 
consolidated amended shareholder derivative complaint on behalf of Nominal Defendant, Mammoth Energy Services, 
Inc., and against Arty Straehla, Mark Layton, Arthur Amron, Paul V. Heerwagen IV, Marc McCarthy, Jim Palm, Matthew 
Ross, Arthur Smith, Gulfport Energy Corporation, and Wexford Capital LP. On February 18, 2020, the defendants filed a 
motion to stay this action. The Company believes the plaintiffs’ claims are without merit and will vigorously defend the 
action. However, at this time, the Company is not able to predict the outcome of this lawsuit or whether it will have a 
material impact on the Company's business, financial condition, results of operations or cash flows.

On September 10, 2019, the U.S. District Court for the District of Puerto Rico unsealed an indictment that charged the 
former president of Cobra Acquisitions LLC with conspiracy, wire fraud, false statements and disaster fraud. Two other 

F-43

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

individuals were also charged in the indictment. The indictment is focused on the interactions between a former FEMA 
official and the former president of Cobra. Neither the Company nor any of its subsidiaries were charged in the 
indictment. The Company is continuing to cooperate with the related investigation. Given the uncertainty inherent in the 
criminal litigation, it is not possible at this time to determine the potential outcome or other potential impacts that the 
criminal litigation could have on the Company. PREPA has stated in court filings that it may contend the alleged criminal 
activity affects Cobra's entitlement to payment under its contracts with PREPA. Subsequent to the indictment, the 
Company received (i) a preservation request letter from the United States Securities and Exchange Commission (“SEC”) 
related to documents relevant to an ongoing investigation it is conducting and (ii) a civil investigative demand (“CID”) 
from the United States Department of Justice (“DOJ”), which requests certain documents and answers to specific 
interrogatories relevant to an ongoing investigation it is conducting.  Both the SEC and DOJ investigations relate to the 
same subjects as those at issue in the criminal matter. The Company is cooperating with both the SEC and DOJ and is not 
able to predict the outcome of these investigations or if either will have a material impact on the Company’s business, 
financial condition, results of operations or cash flows.

On September 12, 2019, AL Global Services, LLC (“Alpha Lobo”) filed a second amended third-party petition against the 
Company in an action styled Jim Jorrie v. Craig Charles, Julian Calderas, Jr., and AL Global Services, LLC v. Jim Jorrie v. 
Cobra Acquisitions LLC v. ESPADA Logistics & Security Group, LLC, ESPADA Caribbean LLC, Arty Straehla, Ken 
Kinsey, Jennifer Jorrie, and Mammoth Energy Services, Inc., in the 57th Judicial District in Bexar County, Texas. The 
petition alleges that the Company should be held vicariously liable under alter ego, agency and respondeat superior 
theories for Alpha Lobo’s alleged claims against Cobra and Arty Straehla for aiding and abetting, knowing participation in 
and conspiracy to breach fiduciary duty in connection with Cobra’s execution of an agreement with ESPADA Caribbean, 
LLC for security services related to Cobra’s work in Puerto Rico. The Company believes these claims are without merit 
and will vigorously defend the action. However, at this time, the Company is not able to predict the outcome of this 
lawsuit or whether it will have a material impact on the Company's business, financial condition, results of operations or 
cash flows.

On September 16, 2019, Cobra filed a lawsuit against Robert Malcom (“Malcom”) and BHI Energy I Power Services LLC 
in a case styled Cobra Acquisitions v. Robert L. Malcom and BHI Energy I Power Services LLC in the 242nd Judicial 
District, District Court of Hale County, Texas. Cobra alleges Malcom breached his non-compete and non-solicit 
obligations contained in the purchase and sale agreement in which Cobra purchased Higher Power from Malcom. On 
September 16, 2019, the court entered a Temporary Restraining Order enjoining Malcom from competing against Higher 
Power or soliciting its customers and employees. Subsequently, on October 25, 2019, the court entered a Temporary 
Injunction enjoining Malcom from competing against Higher Power or soliciting its customers and employees until the 
time of trial. Cobra is seeking to permanently enjoin Malcom from competing against Higher Power or soliciting its 
customers and employees, and further seeks damages it incurred as a result of Malcom's breach of his non-compete 
agreement. On November 3, 2019, Malcom filed his original counter-petition and third-party petition against Cobra, 
Higher Power, Keith Ellison and Arty Straehla alleging, among other things, breach of contract, conversion, unjust 
enrichment, tortious interference, retaliation, violations of the federal Racketeer Influenced and Corrupt Organizations 
Act, and conspiracy. The Company moved to dismiss these claims and, on January 24, 2020, after the hearing on the 
motion to dismiss, Malcom dismissed his claims without prejudice. As a result, at this time the matter poses no liability to 
Cobra or other Mammoth Inc. entities. 

As of December 31, 2019, PREPA owed the Company approximately $227.0 million for services performed, excluding 
$42.0 million of interest charged on these delinquent balances as of December 31, 2019. The Company believes these 
receivables are collectible. However, PREPA is currently subject to bankruptcy proceedings, which were filed in July 
2017 and are currently pending in the U.S. District Court for the District of Puerto Rico. As a result, PREPA's ability to 
meet its payment obligations is largely dependent upon funding from the Federal Emergency Management Agency or 
other sources. On September 30, 2019, the Company filed a motion with the U.S. District Court for the District of Puerto 
Rico seeking recovery of the amounts owed to the Company by PREPA. PREPA filed a motion to stay the Company's 
motion on the ground that the ongoing criminal proceedings described above against the former president of Cobra and 
two other individuals may affect the recovery of those amounts. On October 17, 2019, the court granted PREPA’s request 
to stay the Company's motion and, on February 3, 2020, extended the stay until a status conference to be held on June 17, 
2020. In the event PREPA (i) does not have or does not obtain the funds necessary to satisfy its obligations to Cobra under 
the contracts, (ii) obtains the necessary funds but refuses to pay the amounts owed to the Company or (iii) otherwise does 
not pay amounts owed to the Company for services performed, the receivable may not be collectible.

On December 18, 2019, Gulfport filed a lawsuit against Stingray Pressure Pumping in the Superior Court of the State of 
Delaware. Pursuant to the complaint, Gulfport seeks to terminate the October 1, 2014, Amended and Restated Master 
F-44

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Services Agreement for Pressure Pumping Services between Gulfport and Stingray Pressure Pumping (“MSA”).  In 
addition, Gulfport alleges breach of contract and seeks damages for alleged overpayments and audit costs under the MSA 
and other fees and expenses associated with this lawsuit. The Company believes these claims are without merit and will 
vigorously defend the action. However, at this time, the Company is not able to predict the outcome of this lawsuit or 
whether it will have a material impact on the Company's business, financial condition, results of operations or cash flows.

On January 21, 2020, Mastec Renewables Puerto Rico, LLC (“Mastec”) filed a lawsuit against Mammoth Inc., and Cobra, 
in the U.S. District Court in the Southern District of Florida. Pursuant to its complaint, Mastec asserts claims against the 
Company and Cobra for violations of the federal Racketeer Influenced and Corrupt Organizations Act, tortious 
interference and violations of Puerto Rico state laws. Mastec alleges that it sustained injuries to its business and property 
in the alleged amount of $500 million because of the Company’s and Cobra’s wrongful interference, payment of bribes, 
and other inducement to a FEMA official in order to secure two infrastructure contracts to aid in the rebuilding of the 
energy infrastructure in Puerto Rico after Hurricane Maria. The Company believes these claims are without merit and will 
vigorously defend the action. However, at this time, the Company is not able to predict the outcome of this lawsuit or 
whether it will have a material impact on the Company's business, financial condition, 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 impact 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 years 
ended December 31, 2019 and 2018 the Company paid $3.3 million and $5.6 million, respectively, in contributions to the 
plan. The Company did not pay any contributions for the year ended December 31, 2017.

21.  Reporting Segments and Geographic Areas

Reporting Segments

As of December 31, 2019, our revenues, income before income taxes and identifiable assets are primarily attributable to 
four reportable segments. The Company principally provides electric infrastructure services to private utilities, public 
investor-owned utilities and co-operative utilities and services in connection with on-shore drilling of oil and natural gas 
wells for small to large domestic independent oil and natural gas producers. 

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) less impairment expense, 
as well as a qualitative basis, such as nature of the product and service offerings and types of customers. 

In 2018, the Company had three reportable segments, including pressure pumping services, infrastructure services and 
natural sand proppant services. Based on its assessment of FASB ASC 280, Segment Reporting, guidance at December 31, 
2019, the Company changed its reportable segment presentation in 2019 to include its drilling services, which includes 
Bison Drilling, Bison Trucking, Panther Drilling, Mako Acquisitions and White Wing Tubular, as its own reportable 
segment. The results of the entities were previously included in the reconciling column titled “All Other” in the tables 
below for the years ended December 31, 2018 and 2017. As of December 31, 2019, the Company’s four reportable 
segments include infrastructure services (“Infrastructure”), pressure pumping services (“Pressure Pumping”), natural sand 
proppant services (“Sand”) and drilling services (“Drilling”). The results for the years ended December 31, 2018 and 2017 
have been retroactively adjusted to reflect his change in reportable segments.

During the periods presented, the infrastructure services segment provided 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 pressure pumping services segment provides 
F-45

MAMMOTH ENERGY SERVICES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

hydraulic fracturing services primarily in the Utica Shale of Eastern Ohio, Marcellus Shale in Pennsylvania, Eagle Ford 
and Permian Basins in Texas and the mid-continent region. 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. 

During the periods presented, the Company also provided coil tubing services, flowback services, cementing services, 
acidizing services, equipment rental services, crude oil hauling services, full service transportation 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 
met the quantitative thresholds of a reporting segment and did not meet the aggregation criteria set forth in ASC 
280 Segment Reporting for the year ended December 31, 2019. 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):
