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 Quarterly Report on Form 10-Q (this “report” or “Quarterly Report”):
Acidizing			To pump acid into a wellbore to improve a well’s productivity or injectivity.
Blowout			An uncontrolled flow of reservoir fluids into the wellbore, and sometimes catastrophically to the surface. A blowout may consist of salt water, oil, natural gas or a mixture of these. Blowouts can occur in all types of exploration and production operations, not just during drilling operations. If reservoir fluids flow into another formation and do not flow to the surface, the result is called an underground blowout. If the well experiencing a blowout has significant open-hole intervals, it is possible that the well will bridge over (or seal itself with rock fragments from collapsing formations) down-hole and intervention efforts will be averted.
Bottomhole assembly			The lower portion of the drillstring, consisting of (from the bottom up in a vertical well) the bit, bit sub, a mud motor (in certain cases), stabilizers, drill collar, heavy-weight drillpipe, jarring devices (“jars”) and crossovers for various threadforms. The bottomhole assembly must provide force for the bit to break the rock (weight on bit), survive a hostile mechanical environment and provide the driller with directional control of the well. Oftentimes the assembly includes a mud motor, directional drilling and measuring equipment, measurements-while-drilling tools, logging-while-drilling tools and other specialized devices.
Cementing			To prepare and pump cement into place in a wellbore.
Coiled tubing			A long, continuous length of pipe wound on a spool. The pipe is straightened prior to pushing into a wellbore and rewound to coil the pipe back onto the transport and storage spool. Depending on the pipe diameter (1 in. to 4 1/2 in.) and the spool size, coiled tubing can range from 2,000 ft. to 23,000 ft. (610 m to 6,096 m) or greater length.
Completion			A generic term used to describe the assembly of down-hole tubulars and equipment required to enable safe and efficient production from an oil or gas well. The point at which the completion process begins may depend on the type and design of the well.
Directional drilling			The intentional deviation of a wellbore from the path it would naturally take. This is accomplished through the use of whipstocks, bottomhole assembly (BHA) configurations, instruments to measure the path of the wellbore in three-dimensional space, data links to communicate measurements taken down-hole to the surface, mud motors and special BHA components and drill bits, including rotary steerable systems, and drill bits. The directional driller also exploits drilling parameters such as weight on bit and rotary speed to deflect the bit away from the axis of the existing wellbore. In some cases, such as drilling steeply dipping formations or unpredictable deviation in conventional drilling operations, directional-drilling techniques may be employed to ensure that the hole is drilled vertically. While many techniques can accomplish this, the general concept is simple: point the bit in the direction that one wants to drill. The most common way is through the use of a bend near the bit in a down-hole steerable mud motor. The bend points the bit in a direction different from the axis of the wellbore when the entire drillstring is not rotating. By pumping mud through the mud motor, the bit turns while the drillstring does not rotate, allowing the bit to drill in the direction it points. When a particular wellbore direction is achieved, that direction may be maintained by rotating the entire drillstring (including the bent section) so that the bit does not drill in a single direction off the wellbore axis, but instead sweeps around and its net direction coincides with the existing wellbore. Rotary steerable tools allow steering while rotating, usually with higher rates of penetration and ultimately smoother boreholes.
Down-hole			Pertaining to or in the wellbore (as opposed to being on the surface).
Down-hole motor			A drilling motor located in the drill string above the drilling bit powered by the flow of drilling mud. Down-hole motors are used to increase the speed and efficiency of the drill bit or can be used to steer the bit in directional drilling operations. Drilling motors have become very popular because of horizontal and directional drilling applications and the day rates for drilling rigs.
Drilling rig			The machine used to drill a wellbore.
Drillpipe or Drill pipe			Tubular steel conduit fitted with special threaded ends called tool joints. The drillpipe connects the rig surface equipment with the bottomhole assembly and the bit, both to pump drilling fluid to the bit and to be able to raise, lower and rotate the bottomhole assembly and bit.
Drillstring or Drill string			The combination of the drillpipe, the bottomhole assembly and any other tools used to make the drill bit turn at the bottom of the wellbore.
Flowback			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.
Horizontal drilling			A subset of the more general term “directional drilling,” used where the departure of the wellbore from vertical exceeds about 80 degrees. Note that some horizontal wells are designed such that after reaching true 90-degree horizontal, the wellbore may actually start drilling upward. In such cases, the angle past 90 degrees is continued, as in 95 degrees, rather than reporting it as deviation from vertical, which would then be 85 degrees. Because a horizontal well typically penetrates a greater length of the reservoir, it can offer significant production improvement over a vertical well.
Hydraulic fracturing			A stimulation treatment routinely performed on oil and gas wells in low permeability reservoirs. Specially engineered fluids are pumped at high pressure and rate into the reservoir interval to be treated, causing a vertical fracture to open. The wings of the fracture extend away from the wellbore in opposing directions according to the natural stresses within the formation. Proppant, such as grains of sand of a particular size, is mixed with the treatment fluid to keep the fracture open when the treatment is complete. Hydraulic fracturing creates high-conductivity communication with a large area of formation and bypasses any damage that may exist in the near-wellbore area.


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


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

MAMMOTH ENERGY SERVICES, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Nature of Business

Mammoth Energy Services, Inc. (“Mammoth Inc.”, “Mammoth” 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 engineering, design, construction, upgrade, maintenance and repair services to various public and private owned utilities. Its oilfield services division provides a diversified set of services to the exploration and production industry including well completion, natural sand and proppant and drilling services. Additionally, the Company provides aviation services, equipment rentals, remote accommodation services and equipment manufacturing. The Company was incorporated in Delaware in June 2016.

Operations

The Company’s well completion services include equipment and personnel used in connection with the completion and early production of oil and natural gas wells. The Company’s infrastructure services include engineering, design, 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 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 ~~provide~~provided drilling rigs and directional tools for both vertical and horizontal drilling of oil and natural gas wells. The Company also provides other services, including aviation, equipment rentals, remote accommodations and equipment manufacturing.

The Company’s operations are concentrated in North America. The Company operates 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. Decreases in the commodity prices for oil and natural gas would have a material adverse effect on the Company’s results of operations and financial condition. During the periods presented in this report, the Company provided its infrastructure services primarily in the northeastern, southwestern, midwestern and western portions of the United States. 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.

2. Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries and the variable interest entities (“VIE”) for which the Company is the primary beneficiary. See

Note 11. Variable Interest Entity to our unaudited condensed consolidated financial statements included elsewhere in

this report for additional information regarding these entities. All material intercompany accounts and transactions have been eliminated.

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

Reclassifications

Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. Previously, the Company included ~~gains and losses on disposal of assets within Other income, net on the~~Bison Trucking LLC (“Bison Trucking”) in its drilling services segment.

MAMMOTH ENERGY SERVICES, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

~~unaudited condensed consolidated statements of comprehensive (loss) income.~~ The Company now presents ~~gains~~Bison Trucking in the “All Other” reconciling column. See Note 20 for additional detail regarding our reporting segments. There was no impact on previously reported total assets, total liabilities, net income (loss) or equity for the periods presented.

Cash, Cash Equivalents and ~~losses on disposal~~Restricted Cash

All highly liquid investments with an original maturity of ~~assets~~three months or less are considered cash equivalents. Restricted cash as ~~a separate line titled “Gains on disposal~~ of ~~assets, net”.~~December 31, 2023 consisted of amounts held by our previous creditor as collateral for letters of credit and credit card program.

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. Prior to granting credit to customers, the Company analyzes the potential customer’s risk profile by utilizing a credit report, analyzing macroeconomic factors and using its knowledge of the industry, among other factors. Most areas in the continental United States in which the Company operates provide for a mechanic’s lien against the property on which the service is performed if the lien is filed within the statutorily specified time frame. Customer balances are generally considered delinquent if unpaid by the 30th day following the invoice date and credit privileges may be revoked if balances remain unpaid. Interest on delinquent accounts receivable is recognized in other income when chargeable and collectability is reasonably assured.

During the period October 2017 through March 2019, the Company provided infrastructure services in Puerto Rico under master services agreements entered into by Cobra Acquisitions LLC (“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 three ~~and six~~ months ended ~~June 30,~~March 31, 2024 and 2023, ~~and the three and six months ended June 30, 2022,~~ the Company charged interest on delinquent accounts receivable pursuant to the terms of its agreements with PREPA totaling ~~$11.3 million, $22.5 million, $10.2~~$10.5 million and ~~$20.0~~$11.2 million, respectively. These amounts are included in “other income, net” on the unaudited condensed consolidated statements of comprehensive (loss) income. Included in “accounts receivable, net” on the unaudited condensed consolidated balance sheets as of ~~June 30, 2023~~March 31, 2024 and December 31, ~~2022~~2023 were interest charges of ~~$174.5~~$208.0 million and ~~$152.0~~$197.5 million, respectively.

The Company regularly reviews receivables and provides for expected losses through an allowance for ~~doubtful accounts.~~expected credit losses. In evaluating the level of established reserves, the Company makes judgments regarding its customers’ ability to make required payments, economic events and other factors. As the financial condition of customers changes, circumstances develop, or additional information becomes available, adjustments to the allowance for ~~doubtful accounts~~expected credit losses may be required. In the event the Company expects 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~~expected credit losses once a final determination is made regarding their collectability.

Following is a roll forward of the changes in our allowance for ~~doubtful accounts~~expected credit losses for the year ended December 31, ~~2022~~2023 and the ~~six~~three months ended ~~June 30, 2023~~March 31, 2024 (in thousands):

During the six months ended June 30, 2023 and 2022, the Company has made specific reserves consistent with Company policy which resulted in nominal additions to allowance for doubtful accounts. These additions were charged to bad debt expense based on the factors described above.

~~PREPA~~

~~As of June 30, 2023, PREPA owed Cobra approximately $216.2 million for services performed, excluding $174.5 million~~

MAMMOTH ENERGY SERVICES, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Company has made specific reserves consistent with Company policy which resulted in additions to allowance for expected credit losses totaling $0.2 million and a nominal amount for the three months ended March 31, 2024 and 2023, respectively. These additions were charged to credit loss expense based on the factors described above.

PREPA

As of March 31, 2024, PREPA owed Cobra approximately $140.8 million for services performed, excluding $208.0 million of interest charged on these delinquent balances. 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 (“FEMA”) or other sources. 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 (the “first contract”). 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 (the “second contract”). Since September 30, 2019, ~~Cobra filed a motion with~~we have been pursuing litigation in the U.S. District Court for the District of Puerto Rico and other dispute resolution efforts seeking recovery of the amounts owed to Cobra by PREPA for restoration services in Puerto Rico, which ~~motion~~proceedings are discussed in more detail in Note 19—“Commitments and Contingencies—Litigation” included elsewhere in this report. In connection with these efforts, in 2023, an aggregate of $99 million was ~~stayed~~approved by ~~the Court.~~FEMA for reimbursement to Cobra for services performed by Cobra, of which amount approximately $22.2 million was paid by PREPA to Cobra in 2023. On ~~March 25, 2020,~~December 1, 2023, Cobra, ~~filed an urgent motion to modify the stay order~~as seller, and ~~allow the recovery of approximately $61.7 million in claims related to a tax gross-up provision contained in the emergency master service agreement,~~Mammoth, as ~~amended, that was~~guarantor, entered into an assignment agreement (the “Assignment Agreement”) with SPCP Group, LLC (“SPCP Group”), pursuant to which Cobra transferred to SPCP Group all of its rights, title and interest in $54.4 million of outstanding accounts receivable with PREPA ~~on October 19, 2017. This emergency motion was denied on June 3, 2020~~ and ~~the Court extended the stay~~received net proceeds of ~~our motion.~~$46.1 million. See Note 19—“Commitments and Contingencies—Assignment Agreement” included elsewhere in this report for additional information. On December 9, 2020, the Court again extended the stay of our motion and directed PREPA to file a status report by June 7, 2021. On April 6, 2021, Cobra filed a motion to lift the stay order. Following this filing, PREPA initiated discussion with Cobra, which resulted in PREPA and Cobra filing a joint motion to adjourn all deadlines relative to the April 6, 2021 motion until the June 16, 2021 omnibus hearing as a result of PREPA’s understanding that FEMA would be releasing a report in the near future relating to the emergency master service agreement between PREPA and Cobra that was executed on October 19, 2017. The joint motion was granted by the Court on April 14, 2021. On May 26, 2021, FEMA issued a Determination Memorandum related to the first contract between Cobra and PREPA in which, among other things, FEMA raised two contract compliance issues and, as a result, concluded that approximately $47 million in costs were not authorized costs under the contract. On June 14, 2021, the Court issued an order adjourning Cobra’s motion to lift the stay order to a hearing on August 4, 2021 and directing Cobra and PREPA to meet and confer in good faith concerning, among other things, (i) the May 26, 2021 Determination Memorandum issued by FEMA and (ii) whether and when a second determination memorandum is expected. The parties were further directed to file an additional status report, which was filed on July 20, 2021. On July 23, 2021, with the aid of Mammoth, PREPA filed an appeal of the entire $47 million that FEMA de-obligated in the May 26, 2021 Determination Memorandum. FEMA approved the appeal in part and denied the appeal in part. FEMA found that staffing costs of $24.4 million are eligible for funding. On August 4, 2021, the Court denied Cobra’s April 6, 2021 motion to lift the stay order, extended the stay of our motion seeking recovery of amounts owed to Cobra and directed the parties to file an additional joint status report, which was filed on January 22, 2022. On January 26, 2022, the Court extended the stay and directed the parties to file a further status report by July 25, 2022. On June 7, 2022, Cobra filed a motion to lift the stay order. On June 29, 2022 the Court denied Cobra’s motion and extended the stay to January 2023. On November 21, 2022, FEMA issued a Determination Memorandum related to the 100% federal funded portion of the second contract between Cobra and PREPA in which FEMA concluded that approximately $5.6 million in costs were not authorized costs under the contract. On December 21, 2022, FEMA issued a Determination Memorandum related to the 90% federal cost share portion of the second contract between Cobra and PREPA in which FEMA concluded that approximately $68.1 million in costs were not authorized costs under the contract. PREPA has filed first-level administrative appeals of the November 21, 2022 and December 21, 2022 Determination Memorandums. On January 7, 2023, Cobra and PREPA filed a joint status report with the Court, in which PREPA requested that the Court continue the stay through July 31, 2023 and Cobra requested that the stay be lifted. On January 18, 2023, the Court entered an order extending the stay and directing the parties to file a further status report addressing (i) the status of any administrative appeals in connection with the November and December determination memorandums regarding the second contract, (ii) the status of the criminal case against the former Cobra president and the FEMA official that concluded in December 2022, and (iii) a summary of the outstanding and unpaid amounts arising from the first and second contracts and whether PREPA disputes Cobra’s entitlement to these amounts with the Court by July 31, 2023. On March 27, 2023, Cobra was notified that FEMA had approved $233 million in Cobra invoices related to the December 21, 2022 Determination Memorandum.The 90% federal cost share of this approved amount was $210 million, which was obligated and made available for draw down on March 27, 2023. Of this $210 million, approximately $99 million has been represented by both PREPA and FEMA as intended to pay Cobra for outstanding invoices and the remaining $111 million is a reimbursement to PREPA for payments already made on Cobra invoices. On May 16, 2023, Cobra filed a motion to lift the stay order. In a June 8, 2023 hearing, the Court ordered PREPA to provide Cobra a detailed report on the status of their review of the invoices that make up the aforementioned $99 million. On June 14, 2023, PREPA paid Cobra approximately $10.8 million, all of which was used to reduce outstanding borrowings under the Company's existing revolving credit facility, as required under the terms thereof. Additionally, on June 14, 2023, PREPA filed a report noting a portion of the approved, but unpaid invoices would be submitted to COR3 within two weeks of the filing and the remainder of the invoices would be submitted to COR3 within four weeks of the filing. Following the passage of the two-week and four-week periods contained in the June 14, 2023 report, Cobra filed an informative motion with the Court regarding the passage of the respective periods and PREPA’s failure to meet the deadlines. The Court ordered PREPA to respond to Cobra’s informative motion, which PREPA did on July 21, 2023.In this Court ordered response, PREPA informed the Court that an additional $8.4 million of invoices had been submitted for payment and that $72 million in FEMA approved costs were awaiting engineer certification.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.

The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The Company’s ~~financial instruments consist~~assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. The Company uses appropriate valuation techniques based on available inputs to measure the fair values of its assets and liabilities.

Level 1 - Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date.

Level 2 - Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level 3 - Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value.

The Company elected the fair value option for measuring the liability of the Assignment Agreement. To estimate the fair value of the liability, the Company used inputs that are not observable in the market (Level 3) based on an income approach. The Company used the contractual settlement amount, imputed interest rate and expected timing of cash flows to estimate the liability using the discounted cash flow model. See Notes 9 and ~~cash equivalents, trade receivables, trade payables, amounts receivable or payable to related parties and debt.~~ 19.

The carrying amount of cash and cash equivalents, restricted cash, trade receivables, trade payables and receivables and payables from related parties ~~and trade payables~~ approximates fair value because of the short-term nature of the instruments. The fair value of debt approximates its carrying value because the cost of borrowing fluctuates based upon market conditions.

New Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment reporting (Topic 280)”, which is intended to improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses. The amendment requires disclosure of significant segment expenses regularly provided to the chief operating decision maker (“CODM”) as well as other segment items,

MAMMOTH ENERGY SERVICES, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

extends certain annual disclosures to interim periods, clarifies the applicability to single reportable segment entities, permits more than one measure of profit or loss to be reported under certain conditions and requires disclosure of the title and position of the CODM. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 31, 2024. We expect to adopt the new disclosures for the year ended December 31, 2024. The Company is currently evaluating the impact that adoption of ASU 2023-07 will have on its disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which requires the annual financial statements to include consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and should be applied on a prospective basis, with a retrospective option. The Company is currently evaluating the impact that adoption of ASU 2023-09 will have on its disclosures.

3. Revenue

The Company’s primary revenue streams include ~~infrastructure~~well completion services, ~~well completion~~infrastructure services, natural sand proppant services, drilling services and other services, which includes aviation, equipment rentals, remote accommodations and equipment manufacturing. See Note 1920 for the Company’s revenue disaggregated by type.

Certain of the Company’s customer contracts include provisions entitling the Company to a termination penalty when the customer invokes its contractual right to terminate prior to the contract’s nominal end date. The termination penalties in the customer contracts vary, but are generally considered substantive for accounting purposes and create enforceable rights and obligations throughout the stated duration of the contract. The Company accounts for a contract cancellation as a contract modification in the period in which the customer invokes the termination provision. The determination of the contract termination penalty is based on the terms stated in the related customer agreement. As of the modification date, the Company updates its estimate of the transaction price using the expected value method, subject to constraints, and recognizes the amount over the remaining performance period.

~~MAMMOTH ENERGY SERVICES, INC.~~

~~NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS~~

Well Completion Services

Well completion 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 well completion 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.

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

Infrastructure Services

Infrastructure services are typically provided pursuant to master service agreements, repair and maintenance contracts or fixed price and non-fixed price installation contracts. Pricing under these contracts may be unit priced, cost-plus/hourly (or time and materials basis) or fixed price (or lump sum basis). Generally, the Company accounts for infrastructure services as a single performance obligation satisfied over time. In certain circumstances, the Company supplies materials that are utilized during the jobs as part of the agreement with the customer. The Company accounts for these infrastructure agreements as multiple performance obligations 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.

MAMMOTH ENERGY SERVICES, INC.

Natural Sand Proppant Services

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

Certain of the Company’s sand supply agreements contain a minimum volume commitment related to sand purchases whereby the Company charges a shortfall payment if the customer fails to meet the required minimum volume commitment. These agreements may also contain make-up provisions whereby shortfall payments can be applied in future periods against purchased volumes exceeding the minimum volume commitment. If a make-up right exists, the Company has future performance obligations to deliver excess volumes of product in subsequent months. In accordance with ASC 606, if the customer fails to meet the minimum volume commitment, the Company will assess whether it expects the customer to fulfill its unmet commitment during the contractually specified make-up period based on discussions with the customer and management’s knowledge of the business. If the Company expects the customer will make-up deficient volumes in future periods, revenue related to shortfall payments will be deferred and recognized on the earlier of the date on which the customer utilizes make-up volumes or the likelihood that the customer will exercise its right to make-up deficient volumes becomes remote. 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. The Company did not recognize any shortfall revenue during the three ~~and six~~ months ended ~~June 30,~~March 31, 2024 or 2023 and did not have any deferred revenue related to shortfall payments. ~~The Company recognized shortfall revenue totaling $2.6 million during the three and six months ended June 30, 2022, respectively.~~

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 beginning in December 2019 and rig hauling operations beginning in April 2020.

Other Services

The Company also provided aviation, equipment rentals, remote accommodations and equipment manufacturing, which are reported under other services. The Company’s 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.

Practical Expedients

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

Impairment of Goodwill

As a result of the ARS sale, we performed an impairment assessment of our goodwill during the third quarter of 2023. Under GAAP, the Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of one or more of its reporting units is greater than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, there is no need to perform any further testing. However, if the Company concludes otherwise, then it is required to perform a quantitative impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded based on that difference.

Based on the qualitative assessment, the Company concluded that it was more likely than not that the carrying value of the Aviation reporting unit was greater than its fair value at September 30, 2023. To determine fair value of the Aviation reporting unit at September 30, 2023, the Company used the income approach. The income approach estimates the fair value based on anticipated cash flows that are discounted using a weighted average cost of capital. As a result, the Company impaired goodwill associated with Cobra Aviation, resulting in a $1.8 million impairment charge during the third quarter of 2023.

~~13.~~14. Leases

Lessee Accounting

The Company recognizes 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 all leases with a term in excess of 12 months. 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 has 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, and equipment 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 of certain assets is deemed to be reasonably certain. The accounting for some of the Company’s leases may require 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

Lessor Accounting

Certain of the Company’s agreements with its customers for ~~drilling~~other 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 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. The Company recognized lease revenue of ~~$0.9~~$0.7 million ~~for~~during each of the three months ended ~~June 30,~~March 31, 2024 and 2023, ~~and 2022, respectively, and $1.6 million for each of the six months ended June 30, 2023 and 2022,~~ respectively, which is included in “services revenue” and “services revenue - related parties” on the unaudited condensed consolidated statements of comprehensive (loss) income.

16. Equity Based Compensation

Upon formation of certain operating entities by Wexford and Gulfport Energy Corporation, 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. These awards were not granted in limited or general partner units. The awards are for interests in the distributable earnings of the members of MEH Sub, Mammoth’s majority equity holder.

On the closing date of Mammoth Inc.’s initial public offering (“IPO”), the unreturned capital balance of Mammoth’s majority equity holder was not fully recovered from its sale of common stock in the IPO. As a result, Payout did not occur and no compensation cost was recorded.

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

For the 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.

~~16.~~17. Stock Based Compensation

The Mammoth Energy Services, Inc. 2016 Incentive Plan, as amended (the “2016 Plan”), authorizes the Company’s Board of Directors or the compensation committee of the Company’s Board of Directors to grant restricted stock, restricted stock units, stock appreciation rights, stock options and performance awards. There was a maximum of 4.5 million shares of common stock reserved for issuance under the 2016 Plan, of which 0.6 million shares of common stock remain available for future grants under the 2016 ~~plan~~Plan as of ~~June 30, 2023.~~March 31, 2024.

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.

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.

Litigation

As of ~~June 30, 2023,~~March 31, 2024, PREPA owed the Company approximately ~~$216.2~~$140.8 million for services performed, excluding ~~$174.5~~$208.0 million of interest charged on these delinquent balances as of ~~June 30, 2023.~~March 31, 2024. 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 FEMA or other sources. On September 30, 2019, Cobra filed a motion with the U.S. District Court for the District of Puerto Rico seeking recovery of the amounts owed to Cobra by PREPA, which motion was stayed by the Court. On March 25, 2020, Cobra filed an urgent motion to modify the stay order and allow the recovery of approximately $61.7 million in claims related to a tax gross-up provision contained in the emergency master service agreement, as amended, that was entered into with PREPA on October 19, 2017. This emergency motion was denied on June 3, 2020 and the Court extended the stay of our motion. On December 9, 2020, the Court again extended the stay of our motion and directed PREPA to file a status motion by June 7, 2021. On April 6, 2021, Cobra filed a motion to lift the stay order. Following this filing, PREPA initiated discussion, which resulted in PREPA and Cobra filing a joint motion to adjourn all deadlines relative to the April 6, 2021 motion until the June 16, 2021 omnibus hearing as a result of PREPA’s understanding that FEMA would release a report in the near future relating to the emergency master service agreement between PREPA and Cobra that was executed on October 19, 2017. The joint motion was granted by the Court on April 14, 2021. On May 26, 2021, FEMA issued a Determination Memorandum related to the first contract between Cobra and PREPA in which, among other things, FEMA raised two contract compliance issues and, as a result, concluded that approximately $47 million in costs were not authorized costs under the contract. On June 14, 2021, the Court issued an order adjourning Cobra’s motion to lift the stay order to a hearing on August 4, 2021 and directing Cobra and PREPA to meet and confer in good faith concerning, among other things, (i) the May 26, 2021 Determination Memorandum issued by FEMA and (ii) whether and when a second determination memorandum is expected. The parties were further directed to file an additional status report, which was filed on July 20,

2021. On July 23, 2021, with the aid of Mammoth, PREPA filed an appeal of the entire $47 million that FEMA de-obligated in the May 26, 2021 Determination Memorandum. FEMA approved the appeal in part and denied the appeal in part. FEMA found that staffing costs of $24.4 million are eligible for funding. On August 4, 2021, the Court extended the stay and directed that an additional status report be filed, which was done on January 22, 2022. On January 26, 2022, the Court extended the stay and directed the parties to file a further status report by July 25, 2022. On June 7, 2022, Cobra filed a motion to lift the stay order. On June 29, 2022 the Court denied Cobra’s motion and extended the stay to January 2023. On November 21, 2022, FEMA issued a Determination Memorandum related to the 100% federal funded portion of the second contract between Cobra and PREPA in which FEMA concluded that approximately $5.6 million in costs were not authorized costs under the contract. On December 21, 2022, FEMA issued a Determination Memorandum related to the 90% federal cost share portion of the second contract between Cobra and PREPA in which FEMA concluded that approximately $68.1 million in costs were not authorized costs under the contract. PREPA ~~has~~ filed first-level administrative appeals of the November 21, 2022 and December 21, ~~2022 Determination Memorandums.~~2022. On January 7, 2023, Cobra and PREPA filed a joint status report with the Court, in which PREPA requested that the Court continue the stay through July 31, 2023 and Cobra requested that the stay be lifted. On January 18, 2023, the Court entered an order extending the stay and directing the parties to file a further status report addressing (i) the status of any administrative appeals in connection with the November and December determination ~~memorandums~~memoranda regarding the second contract, (ii) the status of the criminal case against the former Cobra president and the FEMA official that concluded in December 2022, and (iii) a summary of the outstanding and unpaid amounts arising from the first and second contracts and whether PREPA disputes Cobra’s entitlement to these amounts with the Court by July 31, 2023. On January 20, 2023, Cobra submitted a certified claim for approximately $379 million to FEMA pursuant to the federal Contract Disputes Act. On February 1, 2023, FEMA notified Cobra that it had reviewed the claim and determined that no contract, expressed or implied, exists between FEMA and Cobra. On March 29, 2023, Cobra filed a notice of appeal with the Civilian Board of Contract Appeals related to the certified claim submitted in January 2023. On April 25, 2023, FEMA filed a motion to dismiss Cobra’s appeal alleging lack of jurisdiction. On March 27, 2023, Cobra was

notified that FEMA had approved $233 million in Cobra invoices related to the December 21, 2022 Determination Memorandum. The 90% federal cost share of this approved amount was $210 million, which was obligated and made available for draw down on March 27, 2023. Of this $210 million, approximately $99 million has been represented by both PREPA and FEMA as intended to pay Cobra for outstanding invoices and the remaining $111 million is a reimbursement to PREPA for payments already made on Cobra invoices. On May 16, 2023, Cobra filed a motion to lift the stay order. In a June 8, 2023 hearing, the Court ordered PREPA to provide Cobra a detailed report on the status of their review of the invoices that make up the aforementioned $99 million. On June 14, 2023, PREPA paid Cobra approximately $10.8 million, all of which was used to reduce outstanding borrowings under the ~~Company's existing~~Company’s previous revolving credit facility, as required under the terms thereof. Additionally, on June 14, 2023, PREPA filed a report noting a portion of the approved, but unpaid invoices would be submitted to COR3 within two weeks of the filing and the remainder of the invoices would be submitted to COR3 within four weeks of the filing. Following the passage of the two-week and four-week periods contained in the June 14, 2023 report, Cobra filed an informative motion with the Court regarding the passage of the respective periods and PREPA’s failure to meet the deadlines.The Court ordered PREPA to respond to Cobra’s informative motion, which PREPA did on July 21, 2023.In this Court ordered response, PREPA informed the Court that an additional $8.4 million of invoices had been submitted for payment and that $72 million in FEMA approved costs were awaiting engineer certification. On August 2, 2023, following submission of a joint status report by Cobra and FEMA on July 31, 2023, in which, among other things, PREPA requested the stay be continued and Cobra requested the stay be lifted, the Court entered an order continuing the stay until October 31, 2023 and requiring another joint status report be filed on October 16, 2023. On August 22, 2023, PREPA paid Cobra approximately $2.0 million, all of which was used to reduce outstanding borrowings under the Company’s previous revolving credit facility. On August 30, 2023, Cobra filed an informative motion with the Court regarding the status of the approved, but unpaid invoices. The Court ordered PREPA to respond to Cobra’s informative motion, which PREPA did on September 18, 2023. In this Court ordered response, PREPA informed the Court that the approved, but unpaid invoices were in the process of being entered into PREPA’s system for payment. On September 22, 2023 and October 10, ~~2023.~~2023, PREPA made payments to Cobra of approximately $0.8 million and $5.7 million, respectively, all of which was used to reduce outstanding borrowings under the Company’s previous revolving credit facility. On October 16, 2023 and October 25, 2023, PREPA made additional payments to Cobra of approximately $1.7 million and $1.2 million. Also on October 16, 2023, pursuant to Court’s prior order, the parties submitted a further joint status report. In the joint status report, PREPA informed the Court that, among other things, it intended to process and submit to COR3 for reimbursement the remaining approximately $81 million in approved, but unpaid invoices. In addition, the parties informed the Court that the parties were engaged in mediation to resolve open disputes with respect to other unpaid invoices. On October 19, 2023, the Court entered an order continuing the stay through the earlier of January 31, 2024, and the termination of the mediation, directing the parties to file a further status report with the Court by December 1, 2023, and if the disputes have not been resolved through payment or mediation by January 15, 2024, directed the parties to file a status report by January 16, 2024. On December 1, 2023, Cobra, as seller, and Mammoth, as guarantor, entered into the Assignment Agreement

with SPCP Group. Under the terms and conditions of the Assignment Agreement, Cobra transferred to SPCP Group all of its rights, title and interest in $54.4 million of outstanding accounts receivable with PREPA and received net proceeds of $46.1 million. See below for additional information. On December 4, 2023, following submission of a joint status report by Cobra and FEMA on December 1, 2023, in which, among other things, PREPA reported that they submitted a request for reimbursement to COR3 on November 1, 2023 for $82.4 million and is disputing approximately $1.5 million of invoices from Cobra, the Court ordered PREPA to provide a detailed summary of each of their objections to the disputed amounts and directed the parties to report the status of any remaining unpaid approved invoices in connection with the status report due on January 16, 2024. On January ~~20,~~16, 2024, the parties filed a joint status report in which, among other things, PREPA reported that on December 28, 2023, it received a disbursement from COR3 for the amount requested on November 1, 2023 and was in the process of paying Cobra’s assignee approximately $13.4 million, which was paid to SPCP Group on January 18, 2023. Additionally, PREPA reported that it received an order from the Humacao Superior Court requiring it to withhold approximately $9.0 million from any payment otherwise due to Cobra ~~submitted a certified claim for approximately $379 million to FEMA pursuant~~stemming from an alleged unpaid debt of municipal and construction excise taxes and noted that it is aware of twelve Puerto Rico Superior Court cases filed against Cobra by different municipalities relating to the ~~federal Contract Disputes Act.~~same alleged claims for municipal and construction excise taxes, which, in aggregate, total approximately $70.4 million. See below for a more detailed discussion of claims alleging Cobra’s failure to pay construction excise and volume of business taxes. As a result of these alleged claims, PREPA informed the Court that it would withhold the release of any further funds to Cobra. On January 17, 2024, Cobra filed a Writ of Certiorari requesting the Court of Appeals to reverse the order from the Humacao Superior Court. On January 19, 2024, the Court extended the previously ordered stay in the proceedings through April 5, 2024, and directed the parties to file a joint status report by March 27, 2024. On February ~~1, 2023, FEMA notified~~15, 2024, Cobra’s request was granted by the Court of Appeals and the order instructing PREPA to withhold the $9.0 million payment from Cobra was revoked. On February 26, 2024, PREPA paid $50.6 million, of which $9.6 million was paid to Cobra and $41.0 million was paid to SPCP Group, as Cobra’s assignee under the Assignment Agreement, which fully extinguished Cobra’s and Mammoth’s obligations to SPCP Group under the Assignment Agreement, and the Assignment Agreement was terminated. On March 27, 2024, the parties filed a joint status report in which, among other things, PREPA informed the Court that it ~~had reviewed~~was withholding the ~~claim~~release of FEMA approved funds for reimbursement to Cobra totaling approximately $18.2 million due to municipal and ~~determined that no contract, expressed or implied, exists between FEMA~~construction excise tax claims against Cobra.

On May 13, 2021, Foreman Electric Services, Inc. (“Foreman”) filed a petition against Mammoth Inc. and Cobra in the Oklahoma County District Court (Oklahoma State Court). The petition asserted claims against the Company and Cobra under federal ~~RICO~~Racketeer Influenced and Corrupt Organizations Act (“RICO”) statutes and certain state-law causes of action. Foreman alleged that it sustained injuries to its business and property in the amount of $250 million due to the Company’s and Cobra’s alleged wrongful interference by means of inducements to a FEMA official. On May 18, 2021, the Company removed this action to the United States District Court for the Western District of Oklahoma and filed a motion to dismiss on July 8, 2021. On July 29, 2021, Foreman voluntarily dismissed the action without prejudice. On December 14, 2021, Foreman re-filed its petition against Mammoth Inc. and Cobra in the Oklahoma County District Court (Oklahoma State Court). On December 16, 2021, the Company again removed this action to the United States District Court for the Western District of Oklahoma. Foreman filed a motion to remand this action back to Oklahoma County District Court, which was granted on May 5, 2022. On September 28, 2023, the Company moved to dismiss the petition. On November 16, 2023, rather than respond to the motion, Foreman filed an Amended Petition naming Arty Straehla, Mark Layton and Wexford as additional defendants, added claims for fraudulent transfer arising out of the refinancing of certain debt and sought receivership over Mammoth and Cobra related to allegedly fraudulently transferred assets. The ~~case will now proceed according~~defendants moved to dismiss the Amended Petition, which was denied on March 12, 2024. On February 8, 2024, Foreman filed a ~~schedule~~Motion for Appointment of Receiver. On April 29, 2024, the Court denied that ~~will be set by~~motion. Additionally, on February 6, 2023, Foreman moved to amend a complaint against the former president of Cobra filed in Florida State Court arising from facts similar to those in the pending Oklahoma ~~County District Court.~~action to add, as defendants, Arty Straehla and Mark Layton. On September 15, 2023, Straehla and Layton moved to dismiss the complaint. On January 18, 2024, Foreman voluntarily dismissed the Florida State Court action against Straehla and Layton. In a related matter, on January 12, 2022, a Derivative Complaint on behalf of nominal defendant Machine Learning Integration, LLC (“MLI”), which alleges it would have served as a sub-contractor to Foreman in Puerto Rico, was filed against the Company and Cobra in the U.S. District Court for the District of Puerto Rico alleging essentially the same facts as Foreman’s action and asserting violations of federal RICO statutes and certain non-federal claims. MLI alleges it sustained injuries to its business and property in an unspecified amount because the Company’s and Cobra’s wrongful interference by means of inducements to

a FEMA official prevented Foreman from obtaining work, and thereby prevented MLI, as Foreman’s subcontractor, from obtaining work. These matters are still in the early stages and at this time, the Company is not able to predict the outcome of these claims or whether they will have a material impact on the Company’s business, financial condition, results of operations or cash flows.

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, which the Company appealed. On February 25, 2022, the Company received an unfavorable decision on the appeal. The Company appealed the decision. On August 2, 2023, the Ohio Supreme court affirmed the ruling in part and reversed the ruling in part. The Company is currently awaiting the final assessment. It is not expected to have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

Cobra has been served with ~~ten~~13 lawsuits from municipalities in Puerto Rico alleging failure to pay construction excise and volume of business taxes. On November 14, 2022, the Court entered judgment against Cobra in connection with one of the lawsuits ordering payment of approximately $9.0 million. On January 9, 2023, Cobra appealed the judgment and, on March 20, 2023, the Court confirmed the imposition of approximately $8.5 million related to construction excise taxes. On April 10, 2023, Cobra appealed this judgment, which was denied on May 5, 2023. Cobra filed a motion for reconsideration on May 15, 2023, which was denied. Cobra filed a second motion for reconsideration on June 22, 2023 and is currently awaiting a decision. On December 18, 2023, the Humacao Superior Court issued an order to PREPA to withhold payment of approximately $9.0 million to Cobra. On January 17, 2024, Cobra filed a Writ of Certiorari requesting the Court of Appeals to reverse the order from the Humacao Superior Court. On February 15, 2024, Cobra’s request was granted by the Court of Appeals and the order instructing PREPA to withhold the $9.0 million payment from Cobra was revoked. The case was remanded to the lower Court for continuation of the proceedings in accordance with the Court of Appeals’ order. Cobra believes it is exempt from the construction excise taxes. To the extent Cobra receives an unfavorable judgment, the Company believes that any such taxes in the judgment that relate to the Emergency Master Service Agreement with PREPA executed on October 19, 2017, would be reimbursable to Cobra. 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 April 16, 2019, Christopher Williams, a former employee of Higher Power Electrical, LLC, filed a putative class and collective action complaint titled Christopher Williams, individually and on behalf of all others similarly situated v. Higher Power Electrical, LLC, Cobra Acquisitions LLC, and Cobra Energy LLC in the U.S. District Court for the District of Puerto Rico. On June 24, 2019, the complaint was amended to replace Mr. Williams with Matthew Zeisset as the named plaintiff. The plaintiff alleges the defendant failed to pay overtime wages to a class of workers in compliance with the Fair Labor Standards Act and Puerto Rico law. On August 21, 2019, upon request of the parties, the Court stayed proceedings in the lawsuit and administratively closed the case pending completion of individual arbitration proceedings initiated by Mr. Zeisset and opt-in plaintiffs. Other claimants have subsequently initiated additional individual arbitration proceedings asserting similar claims. During ~~the six months ended June 30,~~ 2023, the Company agreed to settlements in principle with a portion of the claimants. Arbitrations remain pending for the remaining claimants. The Company will continue to vigorously defend the arbitrations. During ~~the six months ended June 30,~~ 2023, the Company recognized an estimated liability related to these complaints, which is included in ~~“Accounts~~“accounts payable” in the ~~unaudited condensed~~accompanying consolidated balance ~~sheet at June 30, 2023.~~sheets. The amount required to resolve these matters may ultimately increase or decrease from ~~our~~the Company’s estimated amount as the matters progress.

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~~two other individuals were also charged in the indictment. The indictment ~~was~~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. On May 18, 2022, the former FEMA official and the former president of Cobra each pled guilty to one-count information charging gratuities related to a project that Cobra never bid upon and was never awarded or received any monies for. On December 13, 2022, the Court sentenced the former Cobra president to custody of the Bureau of Prisons for six months and one day, a term of supervised release of six months and one day and a fine of $25,000. The Court sentenced the FEMA official to custody of the Bureau of Prisons for six months and one day, a term of supervised release of six months and a fine of $15,000. The Court also dismissed the indictment against the two defendants. The Company does not expect any additional activity in the criminal proceeding. Given the uncertainty inherent in criminal litigation, however, it is not possible at this time to determine the potential impacts that the sentencings 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. It is unclear what PREPA’s position will be going forward. Subsequent to the indictment,

Cobra received 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. The aforementioned DOJ investigation is in connection with the issues raised in the criminal matter. Cobra is cooperating with the DOJ and is not able to predict the outcome of this investigation or if it will have a material impact on Cobra’s or the Company’s business, financial condition, results of operations or cash flows. With regard to the ~~previously~~SEC investigation disclosed ~~SEC investigation,~~in previous filings, on July 6, 2022, the SEC sent a letter saying that it had concluded its investigation as to the Company and that based on information the SEC has as of this date, it does not intend to recommend an enforcement action against the Company.

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 trial court granted Cobra, Mammoth and Straehla’s motion to compel Alpha Lobo’s claims against them to arbitration. However, Alpha Lobo has not yet brought its claims in arbitration. Instead, on March 22, 2022, Alpha Lobo filed a Petition for Writ of Mandamus in the Fourth Court of Appeals, San Antonio, Texas, seeking to overturn the order compelling arbitration. The appellate court denied the Mandamus on May 4, 2022, without requesting a response. On June 28, 2022, Alpha Lobo filed a Petition for Writ of Mandamus in the Texas Supreme Court, seeking to overturn the order compelling arbitration. The Texas Supreme Court denied the Mandamus on August 5, 2022, without requesting a response. 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. Additionally, there was a parallel arbitration proceeding in which certain Defendants were seeking a declaratory judgment regarding Cobra’s rights to terminate the Alpha Lobo contract and enter into a new contract with a third-party. On June 24, 2021, the arbitration panel ruled in favor of Cobra.

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.

Assignment Agreement

On December 1, 2023, Cobra, as seller and Mammoth, as guarantor, entered into the Assignment Agreement with SPCP Group, as purchaser.

Under the terms and conditions of the Assignment Agreement, Cobra transferred to SPCP Group, at the purchase rate of 88.0% and free and clear of any liens and claims, all of its rights, title and interest in the first $63.0 million (the “Transferred Amount”) of the total outstanding accounts receivable that remained unpaid by PREPA as of October 6, 2023 (the “PREPA Claim”), received or to be received by Cobra on or after October 6, 2023. Between October 6, 2023 and December 1, 2023, Cobra received payments from PREPA with respect to the PREPA Claim totaling $8.6 million (the “Interim Payment Amount”), resulting in the net Transferred Amount of $54.4 million.

Under the terms and conditions of the Assignment Agreement, any portion of the Transferred Amount that remains outstanding from PREPA from and after March 31, 2024 will thereafter increase monthly at a rate of 1% per month, compounded. Any amount received with respect to the PREPA Claim in excess of the Transferred Amount will be for the benefit of Cobra. If (i) it is determined by a final order of any court of competent jurisdiction that the PREPA Claim is subject to any defense, claim or right of setoff, reduction, avoidance, disallowance, subordination, disgorgement, recharacterization, adversary proceeding or other impairment, whether on contractual, legal or equitable grounds, resulting in the PREPA Claim being disallowed or allowed in an amount less than the Transferred Amount, or (ii) Cobra consents to, or enters into a settlement agreement with PREPA for, the payment that is, in an aggregate amount, less than the Transferred Amount or is otherwise adversely impacting SPCP Group’s rights transferred under the Assignment Agreement, Cobra has agreed to repurchase within 18 months and one day from the receipt of SPCP Group’s written demand, the unpaid portion of the Transferred Amount subject to such disallowance or impairment, multiplied by the purchase rate, plus interest accruing, subject to certain tolling provisions, at a rate of 6% per annum from December 1, 2023 through and including the date of such repurchase.

In connection with the entry into the Assignment Agreement, Mammoth and Cobra obtained the required consents from lenders under the Company’s revolving credit facility with Fifth Third Bank and the Company’s term loan and security agreement with Wexford. Further, under the term loan and security agreement with Wexford, Mammoth is required, among other things, to mandatorily remit to Wexford up to 50% of all amounts that constitute PREPA Claim proceeds, including the proceeds received by Cobra under the Assignment Agreement, to reduce outstanding borrowings under such term loan and security agreement. In connection with the Assignment Agreement, Wexford waived this requirement.

The net proceeds received by Cobra in connection with the Assignment Agreement were $46.1 million. The Company elected the fair value option for measuring the liability to simplify the accounting associated with the Assignment Agreement. As of December 31, 2023, the fair value of the liability was approximately $48.9 million, which is included in “accrued expenses and other current liabilities” in the accompanying consolidated balance sheet and the aggregate unpaid principal balance related to this liability was $54.4 million. During the year ended December 31, 2023, the Company recognized a financing charge totaling $2.8 million.

During the three months ended March 31, 2024, PREPA paid $64.0 million with respect to the outstanding PREPA receivable. Of the $64.0 million, $54.4 million was paid to SPCP Group, as Cobra’s assignee under the Assignment Agreement, which fully extinguished Cobra’s and Mammoth’s obligations to SPCP Group under the Assignment Agreement, and the Assignment Agreement was terminated. The Company recognized a financing charge totaling $5.5 million during three months ended March 31, 2024 related to the termination of the Assignment Agreement, which is included in “interest expense and financing charges, net” in the accompanying consolidated statement of comprehensive loss. The remaining $9.6 million was paid to Cobra. Wexford waived the requirement to mandatorily remit to Wexford up to 50% of all PREPA Claim proceeds in relation to the $9.6 million.

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 ~~six~~three months ended ~~June 30,~~March 31, 2024 and 2023, ~~and 2022,~~ the Company paid ~~$1.1~~$0.5 million and ~~$0.9~~$0.6 million, respectively, in contributions to the plan.

~~19.~~20. Reporting Segments

As of ~~June 30, 2023,~~March 31, 2024, the Company’s revenues, income before income taxes and identifiable assets are primarily attributable to four reportable segments. The Company’s Chief Executive Officer and Chief Financial Officer comprise the Company’s ~~Chief Operating Decision Maker function (“CODM”).~~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 loss less impairment expense, as well as a qualitative basis, such as nature of the product and service offerings and types of customers.

As of ~~June 30, 2023,~~March 31, 2024, the Company’s four reportable segments include well completion services (“Well Completion”), infrastructure services (“Infrastructure”), natural sand proppant services (“Sand”) and drilling services (“Drilling”). The Well Completion segment provides hydraulic fracturing and water transfer services primarily in the Utica Shale of Eastern Ohio, Marcellus Shale in Pennsylvania and the mid-continent region. The Infrastructure segment provides electric utility infrastructure services to government-funded utilities, private utilities, public investor-owned utilities and co-operative utilities in the northeastern, southwestern, midwestern and western portions of the United States. The Sand segment mines, processes and sells sand for use in hydraulic fracturing. The Sand segment primarily services the Utica Shale, Permian Basin, SCOOP, STACK and Montney Shale in British Columbia and Alberta, Canada. During certain of the periods presented, the Drilling segment provided contract land and directional drilling services primarily in the Permian Basin and mid-continent region. During the three months ended March 31, 2023, the Company included Bison Trucking in its Drilling segment. Based on its assessment of FASB ASC 280, Segment Reporting, guidance at December 31, 2023, the Company changed its presentation to move Bison Trucking to the reconciling column titled “All Other”. The results for the three months ended March 31, 2023 have been retroactively adjusted to reflect these changes.

The Company also provided aviation services, equipment rental services, ~~crude oil hauling services,~~ remote ~~accommodation~~accommodations and equipment manufacturing. The businesses that provide these services are distinct operating segments, which the CODM reviews independently when making key operating and resource utilization decisions. None of these operating segments meet the

quantitative thresholds of a reporting segment and do not meet the aggregation criteria set forth in ASC 280 Segment Reporting. Therefore, results for these operating segments are included in the column titled “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 Energy Partners 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.

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.

Overview of Our Industries

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 budgets. 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, storage capacity, shortages of equipment and materials 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 many factors, including the prices of oil and natural gas. In March and April 2020, concurrent with the COVID-19 pandemic and quarantine orders in the U.S. and worldwide, oil prices dropped sharply to below zero dollars per barrel for the first time in history due to factors including significantly reduced demand and a shortage of storage facilities. In 2021, U.S. oil production stabilized as commodity prices increased and demand for crude oil rebounded. We saw improvements in the oilfield services industry and in

~~both pricing and utilization of our well completion and drilling services during 2022. During the first half of~~Throughout 2023, pricing for crude oil and natural gas declined from levels seen in 2022, which slowed down completion activities for our customers, in particular, in the Utica and Marcellus Shale natural gas plays, and, as a result, reduced demand for our well completion services. In the first quarter of 2024, we continued to experience persistent challenges in our well completion business and other oilfield services associated with lower U.S. onshore

activity and sustained weakness in the natural gas basins in which we operate. We expect ~~these factors to~~that this trend will continue ~~through at least~~into the ~~third~~second quarter of ~~2023. Despite this short-term softness, however, we~~2024. We are seeing indications, ~~that~~however, of increased activity levels ~~will begin to ramp back up~~ in the ~~fourth quarter~~back half of ~~2023~~2024 in anticipation of increased natural gas demand, and ~~into 2024, creating the opportunity~~we intend to ~~reactivate additional fleets,~~be strategically positioned to capitalize on this anticipated demand, if ~~appropriate. The ongoing war~~ and related humanitarian crisis in Ukraine, however, could continue to have an adverse impact on the global energy markets and volatility of commodity prices, which could further adversely impact demand for our well completion services.when it ramps up.

In response to market conditions, we ~~have~~ temporarily shut down our cementing and acidizing operations and flowback operations beginning in July 2019, our contract drilling operations beginning in December 2019, our rig hauling operations beginning in April 2020, our coil tubing, pressure control and full service transportation operations beginning in July 2020 and our crude oil hauling operations beginning in July 2021. We continue to monitor the market to determine if and when we can recommence these services.

We are currently operating one of our six pressure pumping fleets. Subject to market conditions, supply chain constraints and liquidity requirements, we have plans to upgrade one spread to Tier 4 dual fuel as well as upgrade two fleets to Tier 2 dual fuel, giving us a total of four dual fuel fleets by year-end 2023. Continuing supply chain disruptions have resulted in backlogs of equipment and replacement parts for our and our competitors’ pressure pumping fleets. Any of these factors may result in the delay of our plans to activate, convert or upgrade our existing pressure pumping fleets in the second half of 2023, which may adversely impact our business, financial condition and cash flow.

Natural Sand Proppant Industry

In our natural sand proppant services business, we experienced a significant decline in demand for our sand proppant in the second half of 2019 and throughout 2020 as a result of completion activity falling due to lower oil demand and pricing, increased capital discipline by our customers, budget exhaustion and the COVID-19 pandemic. Activity rebounded modestly in 2021 and continued to increase throughout 2022 as we saw an increase in the volume of sand sold. Supply constraints from labor shortages have negatively affected West Texas in-basin mine operations and increased demand for Northern White frac sand for the region in 2022. Demand from oil and gas companies in Western Canada and the Marcellus Shale was also strong in 2022. The increase in activity in 2022 resulted in an increase in demand and pricing for our sand, which continued throughout the first quarter of 2023. Demand for our natural sand proppant was adversely impacted in the second quarter of 2023 by the wildfires in Canada, which hindered our ability to transport sand. Notwithstanding the foregoing, our sand business remained resilient during the second quarter of 2023, and we expect both pricing and demand for our sand to remain strong through the remainder of 2023. As discussed above, pricing for crude oil and natural gas declined from levels seen in 2022, which slowed down completion activities ~~in particular, in the Utica~~ and ~~Marcellus natural gas plays, which may~~ adversely ~~impact~~impacted demand for our sand proppant services in ~~those regions.~~the second half of 2023. Although we experienced increased demand for our natural sand proppant services and more favorable pricing during the first quarter of 2024 relative to the fourth quarter of 2023, activity remained suppressed. We expect that this trend will continue into the second quarter of 2024.

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 contracted capacity has provided a baseline of business, which has kept our Taylor and Piranha plants operating and our costs competitive.

Energy Infrastructure Industry

Our infrastructure services business provides engineering, design, 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 engineering, design, 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, midwest and western portions of the United States. We currently have agreements in place with private utilities, public IOUs and Co-Ops.

~~During 2022, operational improvements combined with increased crew count drove enhanced results in our infrastructure services division. Although our~~Our average crew count declined slightly from approximately 9378 crews throughout the fourth quarter of ~~2022~~2023 to approximately 8775 crews throughout the first ~~half~~quarter of 2024.

seeing an uptick in bidding opportunities related to engineering, fiber, and ~~expect bidding activity to ramp up in late 2023~~transmission and ~~into 2024.~~distribution, all of which are areas we believe we have differentiated and specialized capabilities. We continue to focus on operational execution and pursue opportunities within this sector as we strategically structure our service offerings for growth, intending to increase our infrastructure services activity and expand both our geographic footprint and depth of projects, especially in fiber maintenance and installation projects.

We work for multiple utilities primarily across the northeastern, southwestern, midwestern and western portions of the United States. We believe that we are well-positioned to compete for new projects due to the experience of our infrastructure management team, combined with our vertically integrated service offerings. We are seeking to leverage this experience and our service offerings to grow our customer base and increase our revenues in the continental United States over the coming years.

Our infrastructure services business has been adversely impacted by the outstanding amounts owed to us by the Puerto Rico Electric Power Authority, or PREPA, for services performed by our subsidiary, Cobra Acquisitions LLC, or Cobra, in Puerto Rico to restore PREPA’s electrical grid damaged by Hurricane Maria. As of ~~June 30, 2023,~~March 31, 2024, PREPA owed us approximately ~~$216.2~~$140.8 million for services performed excluding approximately ~~$174.5~~$208.0 million of interest charged on these delinquent balances. See Note 2. Basis of Presentation and Significant Accounting Policies—Accounts Receivable of our unaudited condensed consolidated financial statements. 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 FEMA, or other sources. OnSince September 30, 2019, we ~~filed a motion with~~have been pursuing litigation in the U.S. District Court for the District of Puerto Rico and other dispute resolution efforts seeking recovery of the amounts owed to usCobra by PREPA for restoration services in Puerto Rico, which ~~motion was stayed by the Court. On March 25, 2020, we filed an urgent motion to modify the stay order and allow our recovery of approximately $62 million~~proceedings are discussed in claims related to a tax gross-up provision contained in the first contract. This emergency motion was denied on June 3, 2020 and the Court extended the stay of our motion. On December 9, 2020, the Court again extended the stay of our motion and directed PREPA to file a status report by June 7, 2021. On April 6, 2021, we filed a motion to lift the stay order. Following this filing, PREPA initiated discussion with Cobra, which resulted in PREPA and Cobra filing a joint motion to adjourn all deadlines relative to the April 6, 2021 motion until the June 16, 2021 omnibus hearing as a result of PREPA’s understanding that FEMA would be releasing a report in the near future relating to the first contract. The joint motion was granted by the Court on April 14, 2021. On May 26, 2021, FEMA issued a Determination Memorandum related to the first contract between Cobra and PREPA in which, among other things, FEMA raised two contract compliance issues and, as a result, concluded that approximately $47 million in costs were not authorized costs under the contract. On June 14, 2021, the Court issued an order adjourning Cobra’s motion to lift the stay order to a hearing on August 4, 2021 and directing Cobra and PREPA to meet and confer in good faith concerning, among other things, (i) the May 26, 2021 Determination Memorandum issued by FEMA and (ii) whether and when a second determination memorandum is expected. The parties were further directed to file an additional status report, which was filed on July 20, 2021. On July 23, 2021, with our aid, PREPA filed an appeal of the entire $47 million that FEMA de-obligated in the May 26, 2021 Determination Memorandum. FEMA approved the appeal in part and denied the appeal in part. FEMA found that staffing costs of $24.4 million are eligible for funding. On August 4, 2021, the Court denied Cobra’s April 6, 2021 motion to lift the stay order, extended the stay of our motion seeking recovery of amounts owed to Cobra and directed the parties to file an additional joint status report, which was filed on January 22, 2022. On January 26, 2022, the Court extended the stay and directed the parties to file a further status report by July 25, 2022. On June 7, 2022, Cobra filed a motion to lift the stay order. On June 29, 2022 the Court denied Cobra’s motion and extended the stay to January 2023. On November 21, 2022, FEMA issued a Determination Memorandum related to the 100% federal funded portion of the second contract between Cobra and PREPA in which FEMA concluded that approximately $5.6 million in costs were not authorized costs under the contract. On December 21, 2022, FEMA issued a Determination Memorandum related to the 90% federal cost share portion of the second contract between Cobra and PREPA in which FEMA concluded that approximately $68.1 million in costs were not authorized costs under the contract. PREPA has filed first-level administrative appeals of the November 21, 2022 and December 21, 2022 Determination Memorandums. On January 7, 2023, Cobra and PREPA filed a joint status report with the Court, in which PREPA requested that the Court continue the stay through July 31, 2023 and Cobra requested that the stay be lifted. On January 18, 2023, the Court entered an order extending the stay and directing the parties to file a further status report addressing (i) the status of any administrative appeals in connection with the November and December determination memorandums regarding the second contract, (ii) the status of the criminal proceedings against the former Cobra president and the FEMA official that concluded in December 2022, and (iii) a summary of the outstanding and unpaid amounts arising from the first and second contracts and whether PREPA disputes Cobra’s entitlement to these amounts with the Court by July 31, 2023. On March 27, 2023, Cobra was notified that FEMA had approved $233 million in Cobra invoices related to the December 21, 2022 Determination Memorandum. The 90% federal cost share of this approved amount was $210 million, which was obligated and made available for draw down on March 27, 2023. Of this $210 million, approximately $99 million has been represented by both PREPA and FEMA as intended to pay Cobra for outstanding invoices and the remaining $111 million is a reimbursement to PREPA for payments already made on Cobra invoices. On May 16, 2023, Cobra filed a motion to lift the staymore

On December 1, 2023, Cobra, as seller, and Mammoth, as guarantor, entered into an assignment agreement (the “Assignment Agreement”) with SPCP Group, LLC (“SPCP Group”), pursuant to which Cobra transferred to SPCP Group all of ~~their review~~its rights, title and interest in $54.4 million of ~~the invoices that make up the aforementioned $99~~outstanding accounts receivable with PREPA and received net proceeds of $46.1 million. See “—Liquidity and Capital Resources—Cobra Assignment Agreement” for additional information. On ~~June 14, 2023,~~February 26, 2024, PREPA paid ~~Cobra approximately $10.8~~$50.6 million, ~~all~~ of which $9.6 million was ~~used~~paid to ~~reduce outstanding borrowings under our existing revolving credit facility,~~Cobra and $41.0 million was paid to SPCP Group, as ~~required~~Cobra’s assignee under the ~~terms thereof. Additionally, on June 14, 2023, PREPA filed a report noting a portion of~~Assignment Agreement, which fully extinguished Cobra’s and Mammoth’s obligations to SPCP Group under the ~~approved, but unpaid invoices would be submitted to COR3 within two weeks of the filing~~Assignment Agreement, and the ~~remainder of~~Assignment Agreement was terminated. On March 27, 2024, the ~~invoices would be submitted to COR3 within four weeks of the filing. Following the passage of the two-week and four-week periods contained~~parties in the ~~June 14, 2023 report, Cobra~~PREPA proceedings filed ~~an informative motion with the Court regarding the passage of the respective periods and PREPA’s failure to meet the deadlines.The Court ordered PREPA to respond to Cobra’s informative motion, which PREPA did on July 21, 2023.~~In this Court ordered response, PREPA informed the Court that an additional $8.4 million of invoices had been submitted for payment and that $72 million in FEMA approved costs were awaiting engineer certification. On August 2, 2023, following submission of a joint status report ~~by Cobra and FEMA on July 31, 2023,~~ in which, among other things, PREPA ~~requested the stay be continued and Cobra requested the stay be lifted,~~informed the Court ~~entered an order continuing~~that it was withholding the release of FEMA approved funds for reimbursement to Cobra totaling approximately $18.2 million due to municipal and construction excise tax claims against Cobra. Cobra believes it is exempt from the construction excise taxes and strongly disagrees with PREPA’s decision to withhold funds. On March 29, 2024, the Court extended the previously ordered stay ~~until October 31, 2023~~in the proceedings through May 24, 2024, and ~~requiring another~~directed the parties to file a joint status report ~~be filed~~by May 8, 2024. Cobra remains in mediation with PREPA on ~~October 10, 2023.~~

~~On January 20, 2023, Cobra submitted a certified claim~~all open disputes. See Note 19—“Commitments and Contingencies—Litigation” included elsewhere in this report for approximately $379 million to FEMA pursuant to the federal Contract Disputes Act. On February 1, 2023, FEMA notified Cobra that it had reviewed the claim and determined that no contract, expressed or implied, exists between FEMA and Cobra. On March 29, 2023, Cobra filed a notice of appeal with the Civilian Board of Contract Appeals related to the certified claim submitted in January 2023. On April 25, 2023, FEMA filed a motion to dismiss Cobra’s appeal alleging lack of jurisdiction.additional information.

We believe all amounts charged to PREPA were in accordance with the terms of the contracts. Further, we believe these receivables are collectible. However, 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 was 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. On May 18, 2022, the former FEMA official and the former president of Cobra each pled guilty to one-count information charging gratuities related to a project that Cobra never bid upon and was never awarded or received any monies for. On December 13, 2022, the Court sentenced the former Cobra president to custody of the Bureau of Prisons for six months and one day, a term of supervised release of six months and a fine of $25,000. The Court sentenced the FEMA official to custody of the Bureau of Prisons for six months and one day, a term of supervised release of six months and a fine of $15,000. The Court also dismissed the indictment against the two defendants. We do not expect any additional activity in the criminal proceeding. Given the uncertainty inherent in the criminal litigation, however, it is not possible at this time to determine the potential impacts that the sentencings could have on us. 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. It is unclear what ~~PREPA's~~PREPA’s position will be going forward. See Note ~~18.~~19. Commitments and Contingencies to our ~~unaudited condensed~~ consolidated financial statements included elsewhere in this 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 other customers to replace the level of services that we provided to PREPA.

~~Revenue~~. Revenue for the six months ended June 30, 2023 increased $39.8 million, or 26%, to $191.8 million from $152.0 million for the six months ended June 30, 2022. The increase in total revenue is primarily attributable to increases in well completion servicesallowance and ~~infrastructure services revenue. Revenue by operating division was as follows:~~

~~Well Completion Services. Well completion services division revenue increased $27.2 million, or 40%, to $94.9 million for the six months ended June 30, 2023 from $67.7 million for the six months ended June 30, 2022.~~

~~Inter-segment revenues, consisting primarily of revenue derived from our sand segment, was $0.2 million and $0.5 million for the six months ended June 30, 2023 and 2022, respectively.~~

The increase in our well completion services revenue was primarily driven by an increase in pressure pumping services utilization and pricing. The number of stages completed increased 23% to 2,974 for the six months ended June 30, 2023 from 2,415 for the six months ended June 30, 2022. Additionally, sand and chemical materials revenue increased during the six months ended June 30, 2023. An average of 2.6 of our six fleets were active for the six months ended June 30, 2023 as compared to an average of 2.5 fleets for the six months ended June 30, 2022.

~~Infrastructure Services.~~ Infrastructure services division revenue increased $8.0 million, or 16%, to $56.6 million for the six months ended June 30, 2023 from $48.6 million for the six months ended June 30, 2022. The increase in revenue was primarily due to an increase in storm restoration activity, improved pricing for our services and an increase in engineering revenue as a result of increased activity. Average crew count remained flat at 87 crews for each of the six months ended June 30, 2023 and June 30, 2022.

~~Natural Sand Proppant Services.~~ Natural sand proppant services division revenue decreased $0.6 million, or 2%, to $24.0 million for the six months ended June 30, 2023, from $24.6 million for the six months ended June 30, 2022. Inter-segment revenue, consisting primarily of revenue derived from our pressure pumping segment, was a nominal amount for the six months ended June 30, 2023 and $2.4 million, or 10% of total sand revenue, for the six months ended June 30, 2022.

The decrease in our natural sand proppant services revenue was primarily due to declines in freight and shortfall revenue, which was partially offset by a 26% increase in the average sales price per ton of sand sold from $24.24 per ton during the six months ended June 30, 2022 to $30.55 per ton during the six months ended June 30, 2023 and a 14% increase in tons of sand sold from approximately 678,468 tons for the six months ended June 30, 2022 to approximately 775,280 tons for the six months ended June 30, 2023.

~~Drilling Services~~. Drilling services division revenue increased $0.4 million, or 8%, to $5.2 million for the six months ended June 30, 2023 from $4.8 million for the six months ended June 30, 2022. The increase in our drilling services revenue was primarily attributable to increased utilization for our directional drilling business from 42% during the six months ended June 30, 2022 to 44% during the six months ended June 30, 2023.

~~Other Services~~. Other services revenue, consisting of revenue derived from our aviation, equipment rental, crude oil hauling, remote accommodation and equipment manufacturing businesses, increased $2.3 million, or 23%, to $12.1 million for the six months ended June 30, 2023 from $9.8 million for the six months ended June 30, 2022. Inter-segment revenue, consisting primarily of revenue derived from our infrastructure and well completion segments, totaled $0.8 million and $0.6 million for the six months ended June 30, 2023 and 2022, respectively.

The increase in our other services revenue was primarily due to an increase in utilization for our equipment rental business. An average of 270 pieces of equipment was rented to customers during the six months ended June 30, 2023, an increase of 16% from an average of 233 pieces of equipment rented to customers during the six months ended June 30, 2022.~~Additionally, utilization for remote accommodations business increased.~~

~~Cost of Revenue (exclusive of depreciation, depletion, amortization and accretion expense)~~. Cost of revenue, exclusive of depreciation, depletion, amortization and accretion expense, increased $25.9 million from $123.3 million, or 81% of total revenue, for the six months ended June 30, 2022 to $149.2 million, or 78%of total revenue, for the six months ended June 30, 2023. The increase is primarily due to an increase in cost of revenue for the well completion services division. Cost of revenue by operating division was as follows:

~~Well Completion Services~~. Well completion services division cost of revenue, exclusive of depreciation and amortization expense, increased $20.0 million, or 36%, to $76.3 million for the six months ended June 30, 2023 from $56.3 million for the six months ended June 30, 2022, primarily due to an increase in utilization. As a percentage of revenue, our well completion services division cost of revenue, exclusive of depreciation and amortization expense of $9.3 million and $13.2 million for the six months ended June 30, 2023 and 2022, respectively, was 80% and 83% for the six months ended June 30, 2023 and 2022, respectively.

~~Infrastructure Services.~~ Infrastructure services division cost of revenue, exclusive of depreciation and amortization expense, increased $5.1 million, or 13%, to $45.8 million for the six months ended June 30, 2023 from $40.7 million for the six months ended June 30, 2022. As a percentage of revenue, cost of revenue, exclusive of

depreciation and amortization expense of $5.8 million and $8.5 million, respectively, for the six months ended June 30, 2023 and 2022 was 81% and 84% for the six months ended June 30, 2023 and 2022, respectively. The decrease as a percentage of revenue is primarily due to an increase in storm activity, which produces higher margins as well as improved pricing for our services.

~~Natural Sand Proppant Services.~~ Natural sand proppant services division cost of revenue, exclusive of depreciation, depletion and accretion expense, decreased $2.6 million, or 15%, from $17.5 million for the six months ended June 30, 2022 to $14.9 million for the six months ended June 30, 2023. As a percentage of revenue, cost of revenue, exclusive of depreciation, depletion and accretion expense of $3.6 million and $3.9 million for the six months ended June 30, 2023 and 2022, respectively, was 62% and 71% for the six months ended June 30, 2023 and 2022, respectively. The decrease in cost as a percentage of revenue is primarily due to a 26% increase in average sales price.

~~Drilling Services~~. Drilling services division cost of revenue, exclusive of depreciation and amortization expense, increased $0.2 million, or 4%, from $4.7 million for the six months ended June 30, 2022 to $4.9 million for the six months ended June 30, 2023, as a result of increased activity. As a percentage of revenue, our drilling services division cost of revenue, exclusive of depreciation and amortization expense of $2.7 million and $3.3 million, for the six months ended June 30, 2023 and 2022, respectively, was 94% and 98% for the six months ended June 30, 2023 and 2022, respectively. The decrease is primarily due to an increase in utilization of our directional drilling services, resulting in a lower ratio of fixed costs to variable costs.

~~Other Services~~. Other services division cost of revenue, exclusive of depreciation and amortization expense, increased $0.9 million, or 12%, from $7.5 million for the six months ended June 30, 2022 to $8.4 million for the six months ended June 30, 2023. As a percentage of revenue, cost of revenue, exclusive of depreciation and amortization expense of $4.3 million and $5.7 million for the six months ended June 30, 2023 and 2022, respectively, was 69% and 77% for the six months ended June 30, 2023 and 2022, respectively. The decrease as a percentage of revenue is primarily due to an increase in utilization for our equipment rental and accommodations businesses, resulting in a lower ratio of fixed costs to variable costs.

~~Selling, General and Administrative Expenses~~. Selling, general and administrative expenses represent the costs associated with managing and supporting our operations. SG&A expense increased $1.8 million, or 11%, to $18.7 million for the six months ended June 30, 2023 from $16.9 million for the six months ended June 30, 2022 primarily due to an increase in compensation expenses.

~~a. Includes travel-related costs, IT expenses, rent, utilities and other general and administrative-related costs.~~

~~Depreciation, Depletion, Amortization and Accretion~~. Depreciation, depletion, amortization and accretion decreased $9.0 million to $25.6 million for the six months ended June 30, 2023 from $34.6 million for the six months ended June 30, 2022. The decrease is primarily attributable to a decline in property and equipment depreciation expense as a result of lower capital expenditures and existing assets being fully depreciated.

~~Gains on Disposal of Assets, Net. Gains on the disposal of assets were $0.8 million and $3.1 million for the six months ended June 30, 2023 and 2022, respectively.~~

~~Operating Loss.~~ We reported an operating loss of $1.0 million for the six months ended June 30, 2023 compared to $19.7 million for the six months ended June 30, 2022. The reduced operating loss was primarily due to increased activity across all operating divisions as well as a decline in depreciation, depletion, amortization and accretion expense.

~~Interest Expense, Net~~. Interest expense, net increased $1.5 million, or 30%, to $6.5 million for the six months ended June 30, 2023 from $5.0 million for the six months ended June 30, 2022 primarily due to an increase in the interest rate under our revolving credit facility.

~~Other Income, Net.~~ We recognized other income, net of $17.0 million during the six months ended June 30, 2023 compared to other income, net of $19.2 million for the six months ended June 30, 2022. We recognized interest on trade accounts receivable of $22.5 million for the six months ended June 30, 2023 compared to $20.0 million for six months ended June 30, 2022.

~~Income Taxes~~.

Our effective tax rate was 59% for the six months ended June 30, 2023 compared to (139%) for the six months ended June 30, 2022. The effective tax rates for the six months ended June 30, 2023 and 2022 differed from the statutory rate of 21% primarily due to the mix of earnings between the United States and Puerto Rico as well as changes in the valuation allowance.goodwill impairment.

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 (loss) income before depreciation, depletion, amortization and accretion, gains (losses) on disposal of assets, stock based compensation, interest expense and financing charges, net, other income (expense), net (which is comprised of interest on trade accounts receivable and certain legal expenses) and provision for income taxes, further adjusted to add back interest on trade accounts receivable. We exclude the items listed above from net (loss) income 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 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 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).

a.Net working capital (less ~~cash and current portion of long-term debt)~~cash) is a non-GAAP measure and, as of ~~June 30, 2023,~~March 31, 2024, is calculated by subtracting total current liabilities of ~~$205.1~~$123.3 million and cash and cash equivalents of ~~$8.8~~$22.0 million from total current assets of ~~$477.0 million, further adjusted to add current portion of long-term debt of $59.4~~$433.9 million. As of December 31, ~~2022,~~2023, net working capital (less cash and current portion of long-term debt) is calculated by subtracting total current liabilities of ~~$237.2~~$182.6 million and cash and cash equivalents of ~~$17.3~~$16.6 million from total current assets of ~~$496.7 million, further adjusted to add current portion of long-term debt of $83.5~~$496.9 million. Amounts include receivables due from PREPA of ~~$390.7~~$348.8 million at ~~June 30, 2023~~March 31, 2024 and ~~$379.0~~$402.3 million at December 31, ~~2022~~2023 and corresponding liabilities of ~~$52.7~~$61.2 million at ~~June 30, 2023~~March 31, 2024 and ~~$47.6~~$60.6 million at December 31, ~~2022.~~2023. See ~~"Capital~~“Capital Requirements and Sources of ~~Liquidity"~~Liquidity” section below.

As of ~~August 9, 2023,~~April 30, 2024, we had cash on hand of ~~$10.6~~$15.5 million and no outstanding borrowings under our new revolving credit facility ~~of $72.3 million,~~and a borrowing base of ~~$95.6~~$19.9 million, leaving an aggregate of ~~$16.9~~$13.6 million of available borrowing capacity under this facility, after giving effect to ~~$6.4~~$6.3 million of outstanding letters of credit and the requirement to maintain ~~a $10.0 million reserve~~the reserves specified in the new revolving credit facility out of the available borrowing capacity.

Continued prolonged volatility in the capital, financial and/or credit markets due to the COVID-19 pandemic, inflationary pressures or otherwise and volatility in commodity prices and/or adverse macroeconomic conditions may further limit our access to, or increase our cost of, capital or make capital unavailable on terms acceptable to us or at all. In addition, if we are unable to comply with the financial covenants under our existing revolving credit facility, or obtain a waiver of forecasted or actual non-compliance with any such financial covenants from our lenders, or under any replacement credit facilities, and an event of default occurs and remains uncured, our lenders would not be required to lend any additional amounts to us, could elect to increase our interest rate by 200 basis points, or as specified in any such replacement credit facilities, could elect to declare all outstanding borrowings, together with accrued and unpaid interest and fees, to be due and payable, may have the ability to require us to apply all of our available cash to repay our outstanding borrowings and may foreclose on substantially all of our assets.

On August 10, 2023, we entered into two non-binding agreements with lenders to repay and refinance our existing revolving credit facility. We expect to close these refinancing transactions prior to the maturity of our existing revolving credit facility on October 19, 2023, subject to customary closing conditions and closing deliverables; however, no assurance can be provided that these transactions will close on the currently anticipated timeline or at all. If we fail to repay or refinance our existing revolving credit facility prior to maturity, our liquidity, financial position and operations will be materially and adversely affected.

~~Our~~New Revolving Credit Facility and New Term Credit Facility

On October 16, 2023, we entered into the new revolving credit facility and the new term credit facility (each as defined below), which refinanced in full our indebtedness outstanding under, and terminated, the amended and restated revolving credit facility, dated as of October 19, 2018, weas amended (the “existing revolving credit facility”), with us and certain of our direct and indirect subsidiaries, as borrowers, the lenders party thereto from time to time, and PNC Bank, National Association, as a lender and as administrative agent for the lenders.

On October 16, 2023, we, as borrower, and certain of our direct and indirect subsidiaries, as guarantors, entered into ~~an amended and restated~~a revolving credit ~~facility, as subsequently amended,~~agreement with the lenders party thereto and ~~PNC~~Fifth Third Bank, National Association, ~~or PNC,~~ as a lender and as administrative agent for the lenders (“Fifth Third”), as may be subsequently ~~further~~ amended ~~(our "existing~~(the “new revolving credit ~~facility"~~facility”). ~~Under~~The new revolving credit facility provides for revolving commitments in an aggregate amount of up to $75 million. Borrowings under the new revolving credit facility are secured by our ~~existing~~assets, inclusive of the subsidiary companies, and are subject to a borrowing base calculation prepared monthly which includes a requirement to maintain certain reserves as specified in the new revolving credit facility. The new revolving credit facility also contains various affirmative and restrictive covenants. Interest under the new revolving credit facility equals the Tranche Rate (as defined in the new revolving credit facility) plus (i) 1.75%, if the Average Excess Availability Percentage (as defined in the new revolving credit facility) is greater than 66 2/3%, (ii)

2.00% if the Average Excess Availability Percentage is greater than 33 1/3% and less than or equal to 66 2/3%, and (iii) 2.25% if the Average Excess Availability Percentage is less than or equal to 33 1/3%.

As of March 31, 2024 and December 31, 2023, the financial covenant under the new revolving credit facility was the fixed charge coverage ratio of 1.0 to 1.0 which applies only during a Financing Covenant Period (as defined in the new revolving credit facility).

On October 16, 2023, we, as borrower, and certain of our direct and indirect subsidiaries, as guarantors, also entered into a loan and security agreement with the lenders party thereto and Wexford Capital LP, an affiliate of the Company, as administrative agent for the lenders “Wexford”), as may be subsequently amended (the “new term credit facility”). The new term credit facility was approved by the audit committee of our board of directors, consisting entirely of independent directors, as a transaction with a related party.

The new term credit facility provides for term commitments in an aggregate amount equal to $45 million. Borrowings under the new term credit facility are secured by our assets, inclusive of the subsidiary companies. The new term credit facility also contains various affirmative and restrictive covenants. Interest under the new term credit facility equals the SOFR Interest Rate (as defined in the new term credit facility) plus 7.50%, as such margin may be increased pursuant to the terms of the new term credit facility; provided that we may elect to pay all or a portion of the accrued interest due with respect to any Interest Period (as defined in the new term credit facility) ending on or before April 16, 2025, in kind by adding such accrued interest to the principal amount of the outstanding loans thereunder.

In particular, under the new term credit facility, we are required, among other things, to mandatorily remit to ~~PNC~~Wexford up to 50% of all amounts that constitute PREPA Claim Proceeds, as such term is defined in ~~our existing revolving~~the new term credit facility, ~~including the $10.8 million received from PREPA on June 14, 2023, all of~~ which ~~was~~will be used to reduce outstanding borrowings under ~~our existing revolving~~the new term credit facility, as required under the terms thereof. ~~Further, our existing revolving credit facility provides for a reduction~~Wexford waived this requirement in connection with the ~~maximum revolving advance amount~~Assignment Agreement and the $9.6 million received by Cobra from PREPA in ~~an amount equal to 50% of the PREPA Claims Proceeds remitted to PNC, subject to a floor equal to the sum of eligible billed and unbilled accounts receivables.~~February 2024.

At June 30, 2023, we had outstanding borrowings under our revolving credit facility of $59.4 million, a borrowing base of $89.4 million and $13.6 million of available borrowing capacity under this facility, after giving effect to $6.4 million of outstanding letters of credit and the requirement to maintain a $10.0 million reserve out of the available borrowing capacity.

~~As of June 30, 2023, the applicable financial covenants under our revolving credit facility were as follows:~~

•~~the fixed charge coverage ratio was 1.1 to 1.0; and~~

•~~the minimum excess availability covenant was $10.0 million.~~

We were in compliance with the applicable financial covenants under our existing revolving credit facility in effect as of June 30, 2023. For additional information regarding our revolving credit facility, see Note 9. Debt to our unaudited condensed consolidated financial statements included elsewhere in this report.

As of August 9, 2023, our borrowing base was $95.6 million and our outstanding borrowings under our existing revolving credit facility were $72.3 million, leaving an aggregate of $16.9 million of available borrowing capacity, after giving effect to $6.4 million of outstanding letters of credit and the requirement to maintain a $10.0 million reserve out of the available borrowing capacity. If we fail to comply with the financial covenants contemplated by our existing revolving credit facility, or obtain a waiver of forecasted or actual non-compliance with any such financial covenants from our lenders, and an event of default occurs under the new revolving credit facility or the new term credit facility, as applicable, and remains uncured, it ~~will~~could have a material adverse effect on our business, financial condition, liquidity and results of operations. The lenders, as applicable, (i) would not be required to lend any additional amounts to us under the new revolving credit facility, (ii) could elect to increase the interest rate by (x) 200 basis points in connection with an event of default under the new revolving credit facility or (y) 300 basis points with respect to an event of default under the new term credit facility, (iii) could elect to declare all outstanding borrowings, together with accrued and unpaid interest and fees, to be due and payable, (iv) may have the ability to require us to apply all of our available cash to repay outstanding borrowings, and (v) may foreclose on substantially all of our assets. The exercise of remedies under the new revolving credit facility and the new term credit facility are subject to the terms of an intercreditor agreement (the “intercreditor agreement”) between Fifth Third and Wexford and acknowledged by us and certain of our subsidiaries. The new revolving credit facility is currently scheduled to mature on the earlier of (x) July 17, 2028, unless the indebtedness under the new term credit facility is refinanced in accordance with terms of the intercreditor agreement, and (y) October 16, 2028. The new term credit facility is currently scheduled to mature on October 16, 2028.

There were no financial covenants applicable under the new revolving credit facility as of March 31, 2024 and December 31, 2023.

As of April 30, 2024, our borrowing base was $19.9 million and we had no outstanding borrowings under our new revolving credit facility, leaving an aggregate of $13.6 million of available borrowing capacity, after giving effect to $6.3 million of outstanding letters of credit and the requirement to maintain the reserves specified in the new revolving credit facility out of the available borrowing capacity.

Cobra Assignment Agreement

On December 1, 2023, Cobra, as seller, and Mammoth, as guarantor, entered into an assignment agreement (the “Assignment Agreement”) with SPCP Group, LLC (“SPCP Group”), as purchaser. Under the terms and conditions of the Assignment Agreement, Cobra transferred to SPCP Group, at the purchase rate of 88.0% and free and clear of any liens and claims, all of its rights, title and interest in the first $63.0 million (the “Transferred Amount”) of the total outstanding accounts receivable that remained unpaid by PREPA as of October 6, 2023 (the “PREPA Claim”), received or to be received by Cobra on or after October 6, 2023. Between October 6, 2023 and December 1, 2023, Cobra received payments from PREPA with respect to the PREPA Claim totaling $8.6 million (the “Interim Payment Amount”), resulting in the net Transferred Amount of $54.4 million.

~~On August 10, 2023 we~~

Under the terms and conditions of the Assignment Agreement, any portion of the Transferred Amount that remained outstanding from PREPA from and after March 31, 2024 would thereafter increase monthly at a rate of 1% per month, compounded. Any amount received with respect to the PREPA Claim in excess of the Transferred Amount would be for the benefit of Cobra. If (i) it was determined by a final order of any court of competent jurisdiction that the PREPA Claim was subject to any defense, claim or right of setoff, reduction, avoidance, disallowance, subordination, disgorgement, recharacterization, adversary proceeding or other impairment, whether on contractual, legal or equitable grounds, resulting in the PREPA Claim being disallowed or allowed in an amount less than the Transferred Amount, or (ii) Cobra consented to, or entered into ~~two non-binding agreements~~a settlement agreement with ~~lender~~PREPA for, the payment that was, in an aggregate amount, less than the Transferred Amount or was otherwise adversely impacting SPCP Group’s rights transferred under the Assignment Agreement, Cobra agreed to ~~repay~~repurchase within 18 months and ~~refinance our existing revolving credit facility. We expect~~one day from the receipt of SPCP Group’s written demand, the unpaid portion of the Transferred Amount subject to ~~close these refinancing transactions prior~~such disallowance or impairment, multiplied by the purchase rate, plus interest accruing, subject to certain tolling provisions, at a rate of 6% per annum from December 1, 2023 through and including the ~~maturity~~date of ~~our existing~~such repurchase.

In connection with the entry into the Assignment Agreement, Mammoth and Cobra obtained the required consents from lenders under the Company’s revolving credit facility ~~on October 19, 2023, subject~~with Fifth Third Bank and the Company’s term loan and security agreement with Wexford. Further, under the term loan and security agreement with Wexford, Mammoth is required, among other things, to ~~customary closing conditions~~mandatorily remit to Wexford up to 50% of all amounts that constitute PREPA Claim proceeds, including the proceeds received by Cobra under the Assignment Agreement, to reduce outstanding borrowings under such term loan and ~~closing deliverables; however, no assurance can be provided that these transactions will close on~~security agreement. In connection with the ~~currently anticipated timeline or at all. If we fail~~Assignment Agreement, Wexford waived this requirement.

The net proceeds received by Cobra in connection with the Assignment Agreement were $46.1 million. During the three months ended March 31, 2024, PREPA paid $64.0 million with respect to ~~repay or refinance our existing revolving credit facility prior~~the outstanding PREPA receivable. Of the $64.0 million, $54.4 million was paid to ~~maturity, our liquidity, financial position~~SPCP Group, as Cobra’s assignee under the Assignment Agreement, which fully extinguished Cobra’s and ~~operations will be materially~~Mammoth’s obligations to SPCP Group, and ~~adversely affected.~~the Assignment Agreement was terminated. The remaining $9.6 million was paid to Cobra. Wexford waived the requirement to mandatorily remit to Wexford up to 50% of all PREPA Claim proceeds in relation to the $9.6 million.

Repurchase Program Authorization

On August 10, 2023, our board of directors approved a stock repurchase program pursuant to which we would be

authorized to repurchase up to the lesser of $55 million or 10 million shares of its common stock, subject to the ~~expected~~

~~repayment and refinancing of its existing revolving credit facility and other~~ factors discussed below. Following the completion

of the refinancing transactions discussed in this report, any stock repurchases under this program may be made opportunistically

from time to time in open market or privately negotiated transactions in compliance with Rule 10b-18 under the Securities Act

of 1934, as amended, including any 10b5-1 plan, and will be subject to market conditions, applicable legal and contractual

restrictions, liquidity requirements and other factors. The repurchase program has no time limit, does not require us to

repurchase any specific number of shares and may be suspended from time to time, modified or discontinued by our board of

directors at any time. Any common stock repurchased as part of such stock repurchase program will be cancelled and retired. We have not repurchased any shares of our common stock under the stock repurchase program as of March 31, 2024 or to date.

Sale Leaseback Transactions

On December 30, 2020, we entered into an agreement with First National Capital, LLC, or FNC, whereby we agreed to sell certain assets from our infrastructure segment to FNC for aggregate proceeds of $5.0 million. Concurrent with the sale of assets, we entered into a ~~36 month~~36-month lease agreement whereby we lease back the assets at a monthly rental rate of $0.1 million. On December 30, 2023, this lease was extended 12 months. On June 1, 2021, we entered into another agreement with FNC whereby we sold additional assets from our infrastructure segment to FNC for aggregate proceeds of $9.5 million and entered into a 42-month lease agreement whereby we lease back the assets at a monthly rental rate of $0.2 million. On June 1, 2022, we entered into another agreement with FNC whereby we sold additional assets from our infrastructure segment to FNC for aggregate proceeds of $4.6 million and entered into a 42-month lease agreement whereby we lease back the assets at a monthly rental rate of $0.1 million. Under the agreements, we have the option to purchase the assets at the end of the lease term. We recorded a liability for the proceeds received and will continue to depreciate the assets. We imputed an interest rate so that the carrying amount of the financial liabilities will be the expected repurchase price at the end of the ~~initial~~ lease terms.

Equipment Financing Note

In December 2022, we entered into a ~~42 month~~42-month financing arrangement with FNC for the purchase of seven new pressure pumping units for an aggregate value of $9.7 million. Under this arrangement, we ~~have~~ agreed to make monthly principal and interest payments totaling $0.3 million over the term of the agreement. This note iswas secured by the seven pressure pumping units and ~~bears~~bore interest at an imputed rate of approximately 15.0%. This equipment note was paid off on December 22, 2023.

Capital Requirements and Sources of Liquidity

As we pursue our business and financial strategy, we regularly consider which capital resources are available to meet our future financial obligations and liquidity requirement. We believe that our cash on hand, operating cash flow and available borrowings under our ~~existing revolving~~ credit facility and ~~following the completion of the pending refinancing transactions, under the replacement credit facilities,~~term loan facility will be sufficient to meet our short-term and long-term funding requirements, including funding our current operations, planned capital expenditures, debt service obligations and known contingencies. However, if we fail to close our pending refinancing transactions at or prior to maturity of our existing revolving credit facility, our liquidity, financial condition and operations will be materially and adversely affected.

~~Our~~However, our liquidity and future cash flows are subject to a number of variables, including receipt of payments from our customers, including the remaining amounts outstanding under the PREPA ~~and our ability to extend, refinance or repay our revolving credit facility at or prior to its scheduled maturity date of October 19, 2023. On June 14, 2023,~~receivable. During the three months ended March 31, 2024, PREPA paid our subsidiary Cobra approximately ~~$10.8~~$64.0 million ~~all of which~~with respect to the outstanding PREPA receivable. Of the $64.0 million, $54.4 million was ~~used~~paid to ~~reduce outstanding borrowings under our existing revolving credit facility,~~SPCP Group, as ~~required~~Cobra’s assignee under the ~~terms thereof.~~Assignment Agreement, which fully extinguished Cobra’s and Mammoth’s obligations to SPCP Group, and the Assignment Agreement was terminated. The remaining $9.6 million was paid to Cobra. As of ~~June 30, 2023,~~March 31, 2024, PREPA owed Cobra approximately ~~$390.7~~$348.8 million for services performed, including ~~$174.5~~$208.0 million of interest charges.

Throughout 2021 and 2022, we released significant data that we obtained through Freedom of Information Act requests along with reviews of both our work and our contracts by the Federal Emergency Management Agency that, we believe, affirm the work performed by Cobra in Puerto Rico. We believe these documents in conjunction with the current Administration’s focus on the recovery of Puerto Rico and our enhanced lobbying efforts will aid in collecting the outstanding amounts owed to us by PREPA. However, 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 Cobra or (iii) otherwise does not pay amounts owed to Cobra, the remaining PREPA receivable may not be collectible, which may adversely impact our liquidity.

We have revised our ~~2023~~2024 capital expenditure estimate down to approximately ~~$18.0~~$9.0 million from the previously planned ~~2023~~2024 capital budget of ~~$24.0~~$15 million primarily due to lower commodity prices and softer demand for oilfield ~~services and volatility in market conditions.~~services. During the first ~~half~~quarter of ~~2023,~~2024, pricing for ~~crude oil and~~ natural gas ~~declined from levels seen in 2022,~~has remained suppressed, which has slowed down completion activities for our customers, in particular, in the Utica and Marcellus Shale natural gas plays, and, as a result, reduced demand for our well completion services. Capital expenditures will ultimately be dependent upon industry conditions and our financial results. These capital expenditures include ~~$17~~$7.0 million for our well completions segment, $1.0 million for our infrastructure segment and $1$1.0 million for our other businesses. During the ~~six~~three months ended ~~June 30, 2023,~~March 31, 2024, our capital expenditures totaled ~~$10.5~~$4.2 million.

Also, as noted above in this report, in response to market conditions we have (i) temporarily shut down certain of our oilfield service offerings, including coil tubing, pressure control, flowback, crude oil hauling, cementing, acidizing and land drilling services, (ii) idled certain facilities, including our sand processing plant in Pierce County, Wisconsin and (iii) reduced our workforce across all of our operations. We continue to monitor market conditions to determine if and when we will recommence these services and operations and increase our workforce. Any such recommencement and expansion will further increase our liquidity requirements in advance of revenue generation.

In addition, while we regularly evaluate acquisition opportunities, we do not have a specific acquisition budget for ~~2023.~~2024 since the timing and size of acquisitions cannot be accurately forecasted. We intend to continue to evaluate acquisition opportunities, including those in the renewable energy sector as well as transactions involving entities controlled by Wexford. 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 any of the above or other reasons, we may do so through borrowings under a revolving credit facility, joint venture partnerships, sale-leaseback transactions, asset sales, including potential sales of accounts receivable or other financing transactions, offerings of debt or equity securities or other means. Although we expect that our sources of capital will be adequate to fund our short-term and long-term liquidity requirements, 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, satisfy debt services obligations, pay litigation settlement obligations, fund contingencies and/or complete acquisitions that may be favorable to us will be impaired, which would have a material adverse effect on our business, financial condition, results of operations and cash flows.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The demand, pricing and terms for our products and services are largely dependent upon the level of activity for the U.S. oil and natural gas industry, energy infrastructure industry and natural sand proppant industry. Industry conditions are influenced by numerous factors over which we have no control, including, but not limited to: the supply of and demand for oil and natural gas services, energy infrastructure services and natural sand proppant; demand for repair and 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.

In March and April 2020, concurrent with the COVID-19 pandemic and quarantine orders in the U.S. and worldwide, oil prices dropped sharply to below zero dollars per barrel for the first time in history due to factors including significantly reduced demand and a shortage of storage facilities. In 2021, U.S. oil production stabilized as commodity prices increased and demand for crude oil rebounded, many exploration and production companies set their operating budgets based on the prevailing prices for oil and natural gas at the time. Despite improvement in the U.S. and global economic activity, easing of the COVID-19 pandemic and related restrictions, rising energy use and improved commodity prices, the budgets for the publicly traded exploration and production companies remained relatively flat throughout 2021, with any excess cash flows used for debt repayment and shareholder returns, rather than to increase production. We saw improvements in the oilfield services industry and in both pricing and utilization of our well completion and drilling services throughout 2022. During the first half ofThroughout 2023, pricing for crude oil and natural gas declined from levels seen in 2022, which slowed down completion activities for our customers, in particular, in the Utica and Marcellus Shale natural gas plays, and, as a result, reduced demand for our well completion services. ~~Further,~~In the first quarter of 2024, we continued to experience persistent challenges in our well completion business and other oilfield services associated with lower U.S. onshore activity and sustained weakness in the natural gas basins in which we operate. We expect that this trend will continue into the second quarter of 2024. Additionally, the ongoing war ~~and related humanitarian crisis~~ in Ukraine and the recent Israel-Hamas war could continue to have an adverse ~~effect~~impact on the global ~~supply chain~~energy markets and volatility of commodity ~~prices.~~prices, which could further adversely impact demand for our well completion services.

~~Although the~~The levels of activity in the U.S. oil and natural gas exploration and production, energy infrastructure and natural sand proppant industries ~~improved throughout 2022 and the first quarter of 2023, they have historically been and~~ continue to be volatile. We are unable to predict the ultimate impact of ~~the COVID-19 pandemic,~~ the volatility in commodity prices, any changes in the near-term or long-term outlook for our industries or overall macroeconomic conditions on our business, financial condition, results of operations, cash flows and stock price.

Interest Rate Risk

We had a cash and cash equivalents balance of ~~$8.8~~$22.0 million at ~~June 30, 2023.~~March 31, 2024. We do not enter into investments for trading or speculative purposes.

Interest under ~~our existing~~the new revolving credit facility ~~is payable at a base rate,~~equals the Tranche Rate (as defined in the new revolving credit facility) plus an applicable margin, which can fluctuate based on multiple facts, including rates set by the U.S. Federal Reserve (which increased its benchmark interest rate by an aggregate of 4.75 percentage points throughout 2022 and 2023, and may continue to increase interest ~~rates in an effort to counter the persistent inflation)~~rates), the supply and demand for credit and general economic conditions, plus an applicable margin. ~~The applicable margin is currently set at 4.0%, which can be reduced to 3.5%~~Interest under ~~certain circumstances specified~~our new term credit facility equals the SOFR Interest Rate (as defined in ~~our existing~~the new term credit ~~facility.~~facility) plus 7.50%. At ~~June 30, 2023,~~March 31, 2024, we had no outstanding borrowings under the new credit facility and $47.7 million outstanding under our term loan with an interest rate of 12.8%. Based on the outstanding borrowings under our ~~existing revolving credit facility~~term loan as of ~~$59.4 million with~~March 31, 2024, a ~~weighted average interest rate of 11.75%. A~~ 1% increase or decrease in the interest rate ~~at that time~~ would ~~increase~~have increased or ~~decrease~~decreased our interest expense by approximately ~~$0.6~~$0.5 million per year. We do not currently hedge our interest rate exposure.

Foreign Currency Risk

Our remote accommodation business, which is included in our other services division, 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 ~~June 30, 2023,~~March 31, 2024, we had ~~$2.2~~$2.9 million of cash, in Canadian dollars, in Canadian accounts. A 10% increase in the strength of the Canadian dollar versus the U.S. dollar would have resulted in an increase in pre-tax income of approximately $0.1 million as of ~~June 30, 2023.~~March 31, 2024. Conversely, a corresponding decrease in the

strength of the Canadian dollar would have resulted in a comparable decrease in pre-tax income. We have not hedged our exposure to changes in foreign currency exchange rates and, as a result, could incur unanticipated translation gains and losses.

Customer Credit Risk

We are also subject to credit risk due to concentration of our receivables from several significant customers. We generally do not require our customers to post collateral. The inability, delay or failure of our customers to meet their obligations to us due to customer liquidity issues or their insolvency or liquidation may adversely affect our business, financial condition, results of operations and cash flows. This risk may be further enhanced by the ~~COVID-19 pandemic, the~~ volatility in commodity prices, the reduction in demand for our services and challenging macroeconomic conditions.

Specifically, we had receivables due from PREPA totaling ~~$390.7~~$348.8 million, including ~~$174.5~~$208.0 million of interest charges, as of ~~June 30, 2023.~~March 31, 2024. 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 FEMA or other sources. See Note 2. Basis of Presentation and Significant Accounting Policies—Accounts Receivable and —Concentrations of Credit Risk and Significant Customers and Note ~~18.~~19. Commitments and Contingencies—Litigation of our unaudited condensed consolidated financial statements.

Seasonality

We provide infrastructure services in the northeastern, southwestern, midwestern and western portions of the United States. We provide well completion 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 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, Kentucky, Colorado, California, Indiana and Alberta, Canada. A portion of our revenues are generated in Ohio, Wisconsin, Minnesota, 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 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

Although the impact of inflation has been insignificant on our operations in prior years, inflation in the U.S. has been at some of the highest levels in over 40 years, creating inflationary pressure on the cost of services, equipment and other goods in our industries and other sectors and contributing to labor and materials shortages across the supply-chain. Throughout 2022 and early 2023, the Federal Reserve increased its benchmark interest rates by an aggregate of 4.75 percentage points, and may continue increasing benchmark interest rates in the future. If the efforts to control inflation are not successful and inflationary pressures persist, our business, results of operations and financial condition may be adversely affected.

Item 4. Controls and Procedures

Evaluation of Disclosure Control and Procedures

Under the direction of our Chief Executive Officer and Chief Financial Officer, we have established disclosure controls and procedures, as defined in Rule 13a-15(e) and 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 ~~June 30, 2023,~~March 31, 2024, 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 ~~June 30, 2023,~~March 31, 2024, our disclosure controls and procedures are effective.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) that occurred during the quarter ended ~~June 30, 2023~~March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Due to the nature of our business, we are, from time to time, involved in litigation or subject to disputes or claims related to our business activities, including breaches of contractual obligations, workers’ compensation claims, employment related disputes, arbitrations, class actions and other litigation. We are also involved, from time to time, in reviews, investigations, subpoenas and other proceedings (both formal and informal) by governmental agencies regarding our business (collectively, “regulatory matters”), which regulatory matters, if determined adversely to us, could subject us to significant fines, penalties, obligations to change our business practices or other requirements resulting in increased expenses, diminished income and damage to our reputation. In the opinion of our management, none of the pending litigation, disputes or claims against us is expected to have a material adverse effect on our financial condition, cash flows or results of operations, except as disclosed in Note 1819 “Commitments and Contingencies,” of the Notes to Unaudited Condensed Consolidated Financial Statements.

Item 1A. Risk Factors

As of the date of this filing, our Company and operations continue to be subject to the risk factors previously disclosed in Item 1A. Risk Factors in our Annual Report on Form 10-K filed with the SEC on ~~February 24, 2023.~~March 1, 2024. For a discussion of the recent trends and uncertainties impacting our business, see also “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments—Overview of Our Services and Industry Conditions”

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

Not applicable.

Item 4. Mine Safety Disclosures

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

Item 5. Other Information

None of our directors or officers adopted or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading

arrangement during the ~~second~~first quarter ended ~~June 30, 2023.~~March 31, 2024.
