SMART SAND, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(IN THOUSANDS, EXCEPT PER SHARE DATA)

(UNAUDITED)

NOTE 1 — Organization and Nature of Business

The Company was incorporated in July 2011 and is headquartered in Yardley, Pennsylvania. The Company primarily operates as a fully integrated frac and industrial sand supply and services company. The Company offers complete mine to wellsite proppant supply and logistics solutions to our frac sand customers in the oil and natural gas industry. These operations include the excavation, processing and sale of sand, or proppant, for hydraulic fracturing operations as well as proppant logistics and wellsite storage solutions through its SmartSystemsTM products and services. The Company also provides sand to customers for industrial uses through its Industrial Product Solutions (“IPS”), such as glass, foundry, building products, filtration, geothermal, renewables, ceramics, turf & landscape, retail, and recreation.

Sand Mines and Processing Facilities

The Company’s integrated Oakdale facility, with on-site rail infrastructure and wet and dry sand processing facilities, has access to two Class I rail lines which enable the Company to process and cost effectively deliver products to its customers. The Company commenced operations at its mine and processing facility near Oakdale, Wisconsin in July 2012, and subsequently expanded its operations in 2014, 2015 and 2018. Currently, the annual processing capacity at the Oakdale facility is approximately 5.5 million tons.

In September 2020, the Company acquired two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin. The Utica facility annual processing capacity is approximately 1.6 million tons and it has access to the Burlington Northern Santa Fe Class I rail line through the Peru, Illinois transload facility. The Company began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020. The Company currently has no plans to operate the New Auburn facility for the foreseeable future.

In March 2022, the Company acquired a frac sand mine and processing facility in Blair, Wisconsin. The Blair facility has approximately 2.9 million tons of total annual processing capacity and contains an onsite, unit train capable rail terminal with access to the Class 1 Canadian National Railway. The Company commenced operations at the Blair facility in April 2023.

Transload & Logistics Solutions

The Company also offers proppant logistics solutions to its customers through, among other things, its network of in-basin transloading terminals and its SmartSystemsTM wellsite proppant storage and management capabilities. The Company has direct access to four Class I rail lines and the ability to access all Class 1 rail lines within the United States and Canada.

The Company has several in-basin rail terminals. The Company acquired rights in March 2018 to operate a unit train capable transloading terminal in Van Hook, North Dakota to service the Bakken Formation in the Williston Basin. In 2020, the Company, as part of its acquisition of the Utica, Illinois facility, obtained rights to use a rail terminal located in El Reno, Oklahoma. In September 2021, the Company acquired the rights to construct and operate a transloading terminal in Waynesburg, Pennsylvania to service the Appalachian Basin, including the Marcellus and Utica Formations, which became operational in January 2022 and then further expanded in the fourth quarter of 2023. In December 2023 and January 2024, the Company acquired rights to use transloading terminals in Minerva, Ohio and Dennison, Ohio, respectively. These terminals will service the Appalachian Basin and are expected to commence operations in the second quarter of 2024.

The Company’s SmartSystems offer proppant storage solutions that create efficiencies, flexibility, enhanced safety and reliability for customers by providing the capability to unload, store and deliver proppant at the wellsite, as well as having the ability to rapidly set up, takedown and transport the entire system. The SmartDepotTM silo includes passive and active dust suppression technology, along with the capability of gravity-fed operation. The self-contained SmartPath® transloader is a mobile sand transloading system designed to work with bottom dump trailers and features a drive over conveyor, surge bin, and dust collection system. The Company has developed the SmartbeltTM a belt system to pair with its SmartPath, which allows for feeding sand directly into the hopper at the wellsite. Rapid deployment trailers are designed for quick setup, takedown and transportation of the entire SmartSystem, and they detach from the wellsite equipment, which allows for removal from the wellsite during operation. A proprietary software program, the SmartSystem TrackerTM, allows customers to monitor silo-specific information, including location, proppant type and proppant inventory.

NOTE 2 — Summary of Significant Accounting Policies

The information presented below supplements the complete description of our significant accounting policies disclosed in our 2023 Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 11, 2024.

Revision of Previously Issued Financial Statements

The Company has reclassified some prior year line items on its condensed consolidated statements of operations to conform to the current financial statement presentation. These reclassifications have no effect on previously reported total revenue or net income. The Company changed the names and types of revenue that are reported on each line item under revenues. Sand revenue now includes sand sales, shortfall, railcar rental, and transportation. SmartSystems revenue is primarily from the rental of our patented SmartSystems equipment and related services provided to customers. There has been no change in the manner in which we recognize revenue.

Basis of Presentation and Consolidation

The accompanying unaudited quarterly condensed consolidated financial statements (“interim statements”) of the Company are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore do not include all the information and notes required by GAAP. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. All adjustments are of a normal recurring nature. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. The consolidated balance sheet as of December 31, 2023 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2023. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2023.

Use of Estimates

The preparation of interim statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include, but are not limited to: impairment considerations of assets, including intangible assets, fixed assets, and inventory; estimated cost of future asset retirement obligations; fair value of acquired assets and assume liabilities; recoverability of deferred tax assets; inventory reserve; the collectability of receivables; and certain liabilities.

Actual results could differ from management’s best estimates as additional information or actual results become available in the future, and those differences could be material. Additionally, global events such as the ongoing conflict in Ukraine and the recent conflict in the Middle East may affect oil and natural gas prices and significant volatility in the oilfield service sector. The Company is currently unable to estimate the effect of current or future events on its future financial position and results of operations. Therefore, the Company can give no assurances that these events will not have a material adverse effect on its financial position or results of operations.

Employee Retention Credit

The Company qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. As of March 31, 2024 and December 31, 2023, the Company included $522 in prepaid expenses and other current assets on its consolidated balance sheets related to receivables for the employee retention credits. The calculation of the credit was based on employees continued employment and represents a portion of the wages paid to them. For income tax purposes, the credit will result in decreased expense related to the wages it offsets in the period received.

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting, which updates various reportable disclosure requirements, primarily through incremental disclosures of segment expenses in both annual and interim reporting. The Update is effective for the Company as of the annual reporting period beginning January 1, 2024 and interim periods beginning January

1, 2025. While the Company is still in the process of evaluating the effects of ASU 2023-07 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect will be updated note disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes, which updates various disclosures including enhancing the income tax rate reconciliation and income taxes paid disclosures by requiring greater disaggregation of information. The other amendments in this Update are intended to improve the effectiveness and comparability of disclosures. The Update is effective for the Company for the annual reporting period beginning January 1, 2025 and for interim periods beginning January 1, 2026. While the Company is still in the process of evaluating the effects of ASU 2023-07 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect will be updated note disclosures.

Overview

The Company

We are a fully integrated frac and industrial sand supply and services company. We offer complete mine to wellsite proppant supply and logistics solutions to our frac sand customers. We produce low-cost, high quality Northern White sand, which is a premium sand used as proppant used to enhance hydrocarbon recovery rates in the hydraulic fracturing of oil and natural gas wells and for a variety of industrial applications. We also offer proppant logistics solutions to our customers through our in-basin transloading terminals and our SmartSystems™ wellsite storage capabilities. In recent years, we have expanded our product line to offer Industrial Products Solutions (“IPS”) in order to diversify our customer base and markets we serve by offering sand for industrial uses. We market our products and services to oil and natural gas exploration and production companies, oilfield service companies, and industrial manufacturers. We sell our sand through long-term contracts, short-term supply agreements or spot sales in the open market. We provide wellsite proppant storage solutions services and equipment under flexible contract terms custom tailored to meet the needs of our customers. We believe that, among other things: (i) the size and favorable geologic characteristics of our sand reserves; (ii) the strategic location and logistical advantages of our facilities; (iii) our proprietary SmartDepot™ portable wellsite storage silos, SmartPath® transloader and SmartBelt™ conveyor;

(iv), access to all Class I rail lines; and (v) the industry experience of our senior management team make us as a highly attractive provider of sand and logistics services

We incorporated in Delaware in July 2011 and began operations at our Oakdale, Wisconsin facility with 1.1 million tons of annual processing capacity in July 2012. After several expansions, our current annual processing capacity at our Oakdale facility, which has access to both the Canadian Pacific and Union Pacific rail networks, is approximately 5.5 million tons. In 2020, we acquired our Utica, Illinois mine and processing facility, which has an annual processing capacity of approximately 1.6 million tons and access to the Burlington Northern Santa Fe rail network. In March 2022, we acquired our Blair, Wisconsin facility, which has approximately 2.9 million tons of total annual processing capacity and contains an onsite, unit train capable rail terminal with access to the Class 1 Canadian National rail network. We commenced operations at the Blair facility in the second quarter of 2023. Our total annual processing capacity of our operating facilities is approximately 10.0 million tons.

We directly control five in-basin transloading facilities and have access to third party transloading terminals in all operating basins. We operate a unit train capable transloading terminal in Van Hook, North Dakota to service the Bakken Formation in the Williston Basin. We operate this terminal under a long-term agreement with Canadian Pacific Railway. We also serve the Appalachian Basin through three company-controlled terminals. In January 2022, we began operations at a unit train capable transloading terminal in Waynesburg, Pennsylvania, which we expanded in 2023. In December 2023 we acquired the right to operate a terminal in Minerva, Ohio and in January 2024 we acquired the rights to operate a terminal in Dennison, Ohio. We expect these two Ohio terminals to become operational in the second quarter of 2024. We also have rights to use a rail terminal located in El Reno, Oklahoma. These terminals allow us to offer more efficient and sustainable delivery options to our customers. Additionally, we have longstanding relationships with third party terminal operators that allow us access to all oil and natural gas exploration production basins of North America.

We offer to our customers portable wellsite proppant storage and management solutions through our SmartSystems products and services. Our SmartSystems provide our customers with the capability to unload, store and deliver proppant at the wellsite, as well as the ability to rapidly set up, takedown and transport the entire system. This capability creates efficiencies, flexibility, enhanced safety and reliability for customers. Through our SmartSystems wellsite proppant storage solutions, we offer the SmartDepot and SmartDepotXL™ silo systems, SmartPath transloader SmartBelt conveyor, and our rapid deployment trailers. Our SmartDepot silos include passive and active dust suppression technology, along with the capability of a gravity-fed operation. Our self-contained SmartPath transloader is designed to work with bottom dump trailers and features a drive over conveyor, surge bin, and dust collection system. Our SmartBelt conveyor is designed to work with our SmartPath transloader to directly feed sand into the blender. Our rapid deployment trailers are designed for quick setup, takedown and transportation of the entire SmartSystem, which allows for efficient removal from the wellsite during operation. We believe the system has the ability to keep up with any hydraulic fracturing operation. We have also developed a proprietary software program, the SmartSystem Tracker™, which allows our SmartSystems customers to monitor silo-specific information, including location, proppant type and proppant inventory. We believe that our SmartSystems reduce trucking and related fuel consumption for our customers, helping them reduce their carbon footprint in their daily operations.

We have expanded our product line to offer industrial sand through IPS. In 2023, we completed the installation of blending and cooling assets at our Utica, Illinois facility that we believe will provide new opportunities to increase our customer base in the IPS business. While sales of IPS to customers were a small portion of our overall sand sales in 2022 and 2023, we expect to continue to expand and diversify to serve the major industrial markets throughout North America, including glass, foundry, building products, filtration, geothermal, renewables, ceramics, turf & landscape, retail, recreation and more in 2024.

Market Trends

Our historical results of operations and cash flows may not be indicative of results of operations and cash flows to be expected in the future.

During 2023 and through the first quarter of 2024, supply and demand for Northern White Sand has been in relative balance. We saw an increase in the volume of sand sold in the first half of 2023 followed by a slowdown in activity later in the year due to customers having exhausted their budgeted spending earlier in the year. Activity has improved in the first quarter of 2024 as customers ramped up activity based on 2024 budget plans. Pricing for sand moderated in the second half of 2023 due to lower demand and has stabilized in the first quarter of 2024. High levels of inflation have led to increasing operating expenses in 2023 and the first quarter of 2024. Softening economic activities in certain countries, the continuation of the war in Ukraine, the conflict in the Middle East, along with President Biden’s pause on liquified natural gas permits could impact oil and natural

gas prices and overall oil and gas activity thereby leading to substantial volatility in demand and pricing in the future. The continued volatility in oil and natural gas demand and the current availability of sufficient supply of sand has led to continued reluctance by some customers to enter into long-term contracts. As such, some customers have instead trended toward purchasing their frac sand supply in the spot market or under short term supply agreements at current market prices. We cannot predict if pricing trends for our products will continue, increase, decrease or stabilize.

Supplies of high-quality Northern White frac sand are limited to select areas, predominantly in western Wisconsin and limited areas of Minnesota and Illinois. We believe the ability to obtain large contiguous reserves in these areas is a key constraint and can be an important supply consideration when assessing the economic viability of a potential frac sand processing facility. Further constraining the supply and throughput of Northern White frac sand is that not all of the large reserve mines have on-site excavation, processing or logistics capabilities, which impact the long-term competitiveness of these mines due to lower efficiency and higher cost structures. Historically, much of the capital investment in Northern White frac sand mines was used for the development of coarser deposits in western Wisconsin, which is inconsistent with the increasing demand for finer mesh frac sand in recent years. As such, competitors in the Northern White frac sand market have shuttered or idled operations at certain facilities due to the higher demand for finer sands and due to lower cost regional sand sources that has eroded the ongoing economic viability of mines with coarser reserve deposits and inefficient mining and logistics facilities.

Demand in the IPS business is relatively stable as customers are spread over a wide range of industries including glass, foundry, building products, filtration, geothermal, renewables, ceramics, turf & landscape, retail, recreation and more. The IPS business is primarily influenced by macroeconomic drivers such as consumer demand and population growth. We believe that as this business grows, it will provide us with the ability to diversify our sales into more stable, consumer-driven products to help mitigate price volatility in the oil and gas industry.

Revenues

Revenues were $83.1 million and tons sold were approximately 1,336,000 for the three months ended March 31, 2024. Revenues for the three months ended March 31, 2023 were $82.4 million, during which time we sold approximately 1,195,000 tons of sand. The key factors contributing to the increase in revenues for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 were as follows:

•Sand revenue was relatively constant at $79.7 million for the three months ended March 31, 2024 versus $80.0 million for the three months ended March 31, 2023. Total volumes increased by approximately 12%, however, average sand prices were lower in the first quarter of 2024 as supply and demand shifts have become more in balance compared to the same period in 2023. We also recognized higher contractual shortfall revenue in the prior year.

•Smart Systems revenue, was approximately $3.3 million for the three months ended March 31, 2024 compared to $2.3 million for the three months ended March 31, 2023. The increase in SmartSystems revenue was due to higher utilization of our SmartSystems fleet and expanded use of our SmartBelt technology.

Cost of Goods Sold

Cost of goods sold was $71.2 million and $70.7 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The increase was primarily due to higher freight and transloading costs at in-basin terminals as a result of higher volumes sold in the current period.

Gross Profit

Gross profit was $11.8 million and $11.6 million for the three months ended March 31, 2024 and March 31, 2023, respectively. The increase in the gross profit for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023 was primarily due to higher sales volumes partially offset by lower average sales prices of our sand relative to the cost to produce and deliver products to our customers. Smart Systems contributed more to gross profit as a result of higher utilization.

Selling, general and administrative expenses decreased to $10.4 million for the three months ended March 31, 2024 compared to $10.8 million for the three months ended March 31, 2023, due to cost reduction measures put in place by management, which were partially offset by additional costs incurred related to financing activities. Additionally, in the first quarter of 2023, we recorded a $1.9 million net loss on disposal of fixed assets as we reconfigured one of our wet plants to increase the efficiency of its operations and upgraded some of our mining equipment.

Interest Expense, net

We incurred $0.5 million and $0.4 million of net interest expense for the three months ended March 31, 2024 and March 31, 2023, respectively.

Income Tax Expense

For the three months ended March 31, 2024 and March 31, 2023, our effective tax rate was approximately 155.2% and (79.9)%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. The computation of the effective tax rate includes modifications from the statutory rate such as income tax credits, tax depletion deduction, carrybacks, and state apportionment changes, among other items.

As of March 31, 2024, we have recorded a liability for uncertain tax positions included on our balance sheet, related to our depletion deduction methodology. As of March 31, 2024, we determined that it is more likely than not that we will not be able to fully realize the benefits of certain existing deductible temporary differences and have recorded a partial valuation allowance against the gross deferred tax assets, which is included in liabilities, long-term, net on our balance sheet, and a corresponding increase to the income tax expense on our condensed consolidated statement of operations.

Net Loss

Net loss was $0.2 million for the three months ended March 31, 2024 as compared to net loss of $3.6 million for the three months ended March 31, 2023. Gross profit was consistent in both periods. An increase in operating income for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023, was primarily attributable to higher total volumes and lower total selling, general and administrative expenses, driven by cost-saving measures by management to reduce our overall operating costs. The three months ended March 31, 2023 also included a $1.9 million net loss on disposal of fixed assets as we reconfigured one of our wet plants to increase the efficiency of its operations and upgraded some of our mining equipment in the prior period.

Non-GAAP Financial Measures

Contribution margin, EBITDA, Adjusted EBITDA and free cash flow are not financial measures presented in accordance with GAAP. We believe that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing our financial condition and results of operations. Gross profit is the GAAP measure most directly comparable to contribution margin, net income is the GAAP measure most directly comparable to EBITDA and Adjusted

MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(UNAUDITED)

EBITDA and net cash provided by operating activities is the GAAP measure most directly comparable to free cash flow. Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measures. Each of these non-GAAP financial measures has important limitations as analytical tools because they exclude some but not all items that affect the most directly comparable GAAP financial measures. You should not consider contribution margin, EBITDA, Adjusted EBITDA or free cash flow in isolation or as substitutes for an analysis of our results as reported under GAAP. Because contribution margin, EBITDA, Adjusted EBITDA and free cash flow may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Contribution Margin

We use contribution margin, which we define as total revenues less cost of goods sold excluding depreciation, depletion and accretion of asset retirement obligations, to measure our financial and operating performance. Contribution margin excludes other operating expenses and income, including costs not directly associated with the operations of our business such as accounting, human resources, information technology, legal, sales and other administrative activities.

We believe that reporting contribution margin and contribution margin per ton sold provides useful performance metrics to management and external users of our financial statements, such as investors and commercial banks, because these metrics provide an operating and financial measure of our ability, as a combined business, to generate margin in excess of our operating cost base.

Gross profit is the GAAP measure most directly comparable to contribution margin. Contribution margin should not be considered an alternative to gross profit presented in accordance with GAAP. Since contribution margin may be defined differently by other companies in our industry, our definition of contribution margin may not be comparable to similarly titled measures of other companies, thereby diminishing its utility. The following table presents a reconciliation of gross profit to contribution margin.


	Three Months Ended March 31,
		2024		2023
		(in thousands, except per ton amounts)
Revenue		$	83,052	$	82,350
Cost of goods sold		71,241		70,713
Gross profit		11,811		11,637
Depreciation, depletion, and accretion of asset retirement obligations		6,697		6,159
Contribution margin		$	18,508	$	17,796
Contribution margin per ton		$	13.85	$	14.89
Total tons sold		1,336		1,195

Contribution margin was $18.5 million and $17.8 million, or $13.85 and $14.89 per ton sold, for the three months ended March 31, 2024 and 2023, respectively. The increase in overall contribution margin for the three months ended March 31, 2024, when compared to the same period in 2023, was primarily due to higher tons sold and the increased utilization of our SmartSystems fleet. The decrease in contribution margin per ton sold was primarily due to lower average sand sales prices for the three months ended March 31, 2024, compared to the three months ended March 31, 2023.

EBITDA and Adjusted EBITDA

We define EBITDA as net income, plus: (i) depreciation, depletion and amortization expense; (ii) income tax expense (benefit) and other results of operations based taxes; and (iii) interest expense. We define Adjusted EBITDA as EBITDA, plus: (i) gain or loss on sale of fixed assets or discontinued operations; (ii) integration and transition costs associated with specified transactions; (iii) equity compensation; (iv) acquisition and development costs; (v) non-recurring cash charges related to

(UNAUDITED)

restructuring, retention and other similar actions; (vi) earn-out, contingent consideration obligations; and (vii) non-cash charges and unusual or non-recurring charges. Adjusted EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors and commercial banks, to assess:

•the financial performance of our assets without regard to the impact of financing methods, capital structure or historical cost basis of our assets;

•the viability of capital expenditure projects and the overall rates of return on alternative investment opportunities;

•our ability to incur and service debt and fund capital expenditures;

•our operating performance as compared to those of other companies in our industry without regard to the impact of financing methods or capital structure; and

•our debt covenant compliance, as Adjusted EBITDA is a key component of critical covenants to the ABL Credit Facility.

We believe that our presentation of EBITDA and Adjusted EBITDA will provide useful information to investors in assessing our financial condition and results of operations. Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA should not be considered alternatives to net income presented in accordance with GAAP. Because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, our definitions of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. The following table presents a reconciliation of net loss to EBITDA and Adjusted EBITDA for each of the periods indicated.


	Three Months Ended March 31,
		2024		2023
		(in thousands)
Net loss		$	(216)	$	(3,599)
Depreciation, depletion and amortization		7,200		6,551

Cash charges related to restructuring and retention of employees		107		—
Accretion of asset retirement obligations		249		200
Adjusted EBITDA		$	9,335	$	8,335

Adjusted EBITDA was $9.3 million for the three months ended March 31, 2024 compared to $8.3 million for the three months ended March 31, 2023. The increase in Adjusted EBITDA for the three months ended March 31, 2024, compared to the same period in 2023, was primarily due to higher sales volumes, increased IPS sales and higher utilization of our SmartSystems fleet.

Free Cash Flow

Free cash flow, which we define as net cash provided by operating activities less purchases of property, plant and equipment, is used as a supplemental financial measure by our management and by external users of our financial statements, such as investors and commercial banks, to measure the liquidity of our business.

SMART SAND, INC.

MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(UNAUDITED)

Net cash provided by operating activities is the GAAP measure most directly comparable to free cash flows. Free cash flows should not be considered an alternative to net cash provided by operating activities presented in accordance with GAAP. Because free cash flows may be defined differently by other companies in our industry, our definition of free cash flows may not be comparable to similarly titled measures of other companies, thereby diminishing its utility. The following table presents a reconciliation of net cash provided by (used in) operating activities to free cash flows.


	Three Months Ended March 31,
		2024		2023
		(in thousands, except per ton amounts)
Net cash (used in) provided by operating activities		$	(3,863)	$	5,105

Purchases of property, plant and equipment		(1,646)		(4,018)
Free cash flow		$	(5,509)	$	1,087

Free cash flow was $(5.5) million for the three months ended March 31, 2024 compared to $1.1 million for the three months ended March 31, 2023. The decrease in free cash flow for the three months ended March 31, 2024 was due to a decrease in net cash provided by operating activities for the three months ended March 31, 2024 in comparison to the same period in 2023. The decline in cash provided by operating activities was attributable to an increase in working capital to support higher sales volumes.

Liquidity and Capital Resources

Our primary sources of liquidity are cash flow generated from operations and availability under our ABL Credit Facility and other equipment financing sources. As of March 31, 2024, cash on hand was $4.6 million and we had $6.0 million in undrawn availability on our ABL Credit Facility. We are in the process of refinancing this facility.

Based on our balance sheet, cash flows, current market conditions, and information available to us at this time, we believe that we have sufficient liquidity and other available capital resources, to meet our cash needs for the next twelve months.

Material Cash Requirements

Capital Requirements

We expect full year 2024 capital expenditures to be between $15.0 million and $20.0 million. Our expected capital expenditures for 2024 are primarily for process improvement and efficiency projects at our mine sites, upgrading mining equipment and the build out of our new Ohio terminals. We expect to fund these capital expenditures with cash from operations, equipment financing options available to us or borrowings under the ABL Credit Facility.

Indebtedness

Our debt facilities include the Oakdale Equipment Financing, various notes payable and our ABL Credit Facility. Our Oakdale Equipment Financing is secured by substantially all of the assets at our Oakdale facility. The outstanding balance under the Oakdale Equipment Financing as of March 31, 2024 was $6.9 million. Minimum cash payments on this facility for the remainder of 2024 are anticipated to be $5.7 million. Our various notes payable are primarily secured by heavy equipment purchases as well as some of our manufactured SmartSystems. Total debt under these notes payable as of March 31, 2024 was $3.0 million. Minimum cash payments on these notes payable for the remainder of 2024 are anticipated to be $0.9 million. There was $14.0 million outstanding on our ABL Credit Facility as of March 31, 2024, which matures December 13, 2024. We are in the process of refinancing this facility.

(UNAUDITED)

Operating Leases

We use leases primarily to procure certain office space, railcars and heavy equipment as part of our operations. The majority of our lease payments are fixed and determinable. Our operating lease liabilities as of March 31, 2024 were $21.6 million. Minimum cash payments on operating leases for the remainder of 2024 are anticipated to be $8.3 million.

Mineral Rights Property

The Company is obligated under certain contracts for minimum payments for the right to use land for extractive activities. The annual minimum payments under these contracts are approximately $2.5 million per year in the aggregate for the next 13 years.

Off-Balance Sheet Arrangements

We had outstanding performance bonds of $19.7 million at March 31, 2024.

Contractual Obligations

As of March 31, 2024, we had contractual obligations for the ABL Credit Facility, Oakdale Equipment Financing, notes payable, operating and finance leases, delivery of sand, royalties and similar minimum payments for the rights to mine land, capital expenditures, asset retirement obligations, and other commitments to municipalities for maintenance.

Environmental Matters

We are subject to various federal, state and local laws and regulations governing, among other things, hazardous materials, air and water emissions, environmental contamination and reclamation and the protection of the environment and natural resources. We have made, and expect to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures.

Seasonality

Our business is affected to some extent by seasonal fluctuations in weather that impact the production levels for a portion of our wet sand processing capacity. While our dry plants are able to process finished product volumes evenly throughout the year, same of our excavation and our wet sand processing activities have historically been limited during winter months. As a consequence, we typically have experienced lower cash operating costs in the first and fourth quarter of each calendar year, and higher cash operating costs in the second and third quarter of each calendar year when we have overproduced sand to meet demand in the winter months. These higher cash operating costs are capitalized into inventory and expensed when these tons are sold, which can lead to us having higher overall cost of production in the first and fourth quarters of each calendar year as we expense inventory costs that were previously capitalized. We have indoor wet processing facilities at two of our plant locations, which allow us to produce wet sand inventory year-round to support a portion of our dry sand processing capacity, which may reduce certain of the effects of this seasonality. We may also sell frac sand for use in oil and natural gas producing basins where severe weather conditions may curtail drilling activities and, as a result, our sales volumes to those areas may be reduced during such severe weather periods.

Customer Concentration

For the three months ended March 31, 2024, revenue from Equitable Gas Corporation, Halliburton Energy Services and Encino Energy accounted for 37.4%, 11.4% and 11.2% respectively, of total revenue. For the three months ended March 31, 2023, EQT Production Corporation, Encino Energy, and Liberty Oilfield Services accounted for 32.5%, 13.3%, and 10.8%, respectively, of total revenue.

SMART SAND, INC.

MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(UNAUDITED)

Critical Accounting Policies and Estimates

There have been no material changes in our critical accounting policies and procedures during the three months ended March 31, 2024.

Use of Estimates

The preparation of interim statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include, but are not limited to: impairment considerations of assets, including intangible assets, fixed assets, and inventory; estimated cost of future asset retirement obligations; fair values of acquired assets and assumed liabilities; recoverability of deferred tax assets; inventory reserve; and the collectability of receivables; and certain liabilities.

Actual results could differ from management’s best estimates as additional information or actual results become available in the future, and those differences could be material. Future economic performance is uncertain due to current high inflation and other economic concerns. We continue to actively monitor the global impact of current events, but we are unable to estimate the impact of future events on our financial position and results of operations or give any assurances that these events will not have a material adverse effect on our financial position or results of operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

The majority of our debt is financed under fixed interest rates. Borrowings under the ABL Credit Facility bear interest at a rate per annum equal to an applicable margin, plus, at our option, either a LIBOR rate or an alternate base rate (“ABR”). The applicable margin is 2.00% for LIBOR loans and 1.00% for ABR loans. There was $14.0 million outstanding borrowings under our ABL Credit Facility as of March 31, 2024. We do not believe this represents a material interest rate risk.

We have considered other changes in our exposure to market risks during the three months ended March 31, 2024 and have determined that there have been no additional material changes to our exposure to market risks from those described in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 11, 2024.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There have been no changes in internal control over financial reporting for the quarter ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time we may be involved in litigation relating to claims arising out of our operations in the normal course of business. The disclosure called for by Part II, Item 1 regarding our legal proceedings is incorporated by reference herein from Part I, Item 1. Note 14 - Commitments and Contingencies - Litigation of the notes to the condensed consolidated financial statements in this Form 10-Q for the three months ended March 31, 2024.

ITEM 1A. RISK FACTORS

There have been no material changes to the risk factors described in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

During the three months ended March 31, 2024, no shares were sold by the Company without registration under the Securities Act of 1933, as amended.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

None.

ITEM 4. MINE SAFETY DISCLOSURES

We are committed to maintaining a culture that prioritizes mine safety. We believe that our commitment to safety, the environment and the communities in which we operate is critical to the success of our business. Our sand mining operations are subject to mining safety regulation. The U.S. Mining Safety and Health Administration (“MSHA”) is the primary regulatory organization governing frac sand mining and processing. Accordingly, MSHA regulates quarries, surface mines, underground mines and the industrial mineral processing facilities associated with and located at quarries and mines. The mission of MSHA is to administer the provisions of the Federal Mine Safety and Health Act of 1977 and to enforce compliance with mandatory miner safety and health standards. As part of MSHA’s oversight, representatives perform at least two unannounced inspections annually for each above-ground facility.

We are also subject to regulations by the U.S. Occupational Safety and Health Administration, which has promulgated rules for workplace exposure to respirable silica for several other industries. Respirable silica is a known health hazard for workers exposed over long periods. MSHA is expected to adopt similar rules as part of its “Long Term Items” for rulemaking. Airborne respirable silica is associated with work areas at our site and is monitored closely through routine testing and MSHA inspection. If the workplace exposure limit is lowered significantly, we may be required to incur certain capital expenditures for equipment to reduce this exposure.

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.

Exhibit 95.1

MINE SAFETY DISCLOSURES

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Act”) and Item 104 of Regulation S-K, which requires certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”).

Mine Safety Information

Whenever the Federal Mine Safety and Health Administration (“MSHA”) believes a violation of the Mine Act, any health or safety standard or any regulation has occurred, it may issue a citation which describes the alleged violation and fixes a time within which the U.S. mining operator must abate the alleged violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order removing miners from the area of the mine affected by the condition until the alleged hazards are corrected. When MSHA issues a citation or order, it generally proposes a civil penalty, or fine, as a result of the alleged violation, that the operator is ordered to pay. Citations and orders can be contested and appealed, and as part of that process, may be reduced in severity and amount, and are sometimes dismissed. The number of citations, orders and proposed assessments vary depending on the size and type (underground or surface) of the mine as well as by the MSHA inspector(s) assigned.

Mine Safety Data

The following provides additional information about references used in the table below to describe the categories of violations, orders or citations issued by MSHA under the Mine Act:

•Section 104 S&S Citations: Citations received from MSHA under section 104 of the Mine Act for violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard.

•Section 104(b) Orders: Orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

•Section 104(d) Citations and Orders: Citations and orders issued by MSHA under section 104(d) of the Mine Act for an unwarrantable failure to comply with mandatory health or safety standards.

•Section 110(b)(2) Violations: Flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act.

•Section 107(a) Orders: Orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an “imminent danger” (as defined by MSHA) existed.

Pattern or Potential Pattern of Violations

The following provides additional information about references used in the table below to describe elevated pattern of violation enforcement actions taken by MSHA under the Mine Act:

•Pattern of Violations: A pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under section 104(e) of the Mine Act.

•Potential Pattern of Violations: The potential to have a pattern of violations under section 104(e).

Pending Legal Actions

The following provides additional information of the types of proceedings brought before the Federal Mine Safety and Health Review Commission (“FMSHRC”):

•Contest Proceedings: A contest proceeding may be filed by an operator to challenge the issuance of a citation or order issued by MSHA.

•Civil Penalty Proceedings: A civil penalty proceeding may be filed by an operator to challenge a civil penalty MSHA has proposed for a violation contained in a citation or order. The operator does not institute civil penalty proceedings based solely on the assessment amount of proposed penalties. Any initiated adjudications address substantive matters of law and policy instituted on conditions that are alleged to be in violation of mandatory standards of the Mine Act.

•Discrimination Proceedings: Involves a miner’s allegation that he or she has suffered adverse employment action because he or she engaged in activity protected under the Mine Act, such as making a safety complaint. Also includes temporary reinstatement proceedings involving cases in which a miner has filed a complaint with MSHA stating that he or she has suffered discrimination and the miner has lost his or her position.

•Compensation Proceedings: A compensation proceeding may be filed by miners entitled to compensation when a mine is closed by certain closure orders issued by MSHA. The purpose of the proceeding is to determine the amount of compensation, if any, due to miners idled by the orders.

•Temporary Relief: Applications for temporary relief are applications filed under section 105(b)(2) of the Mine Act for temporary relief from any modification or termination of any order.

•Appeals: An appeal may be filed by an operator to challenge judges’ decisions or orders to the Commission, including petitions for discretionary review and review by the Commission on its own motion.

(1)The definition of mine under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting from, the work of extracting minerals, such as land, structures, facilities, equipment, machines, tools

and minerals preparation facilities. Unless otherwise indicated, any of these other items associated with a single mine have been aggregated in the totals for that mine. MSHA assigns an identification number to each mine and may or may not assign separate identification numbers to related facilities such as preparation facilities. We are providing the information in the table by mine rather than MSHA identification number because that is how we manage and operate our mining business and we believe this presentation will be more useful to investors than providing information based on MSHA identification numbers.

(2)Represents the total dollar value of the proposed assessments from MSHA under the Mine Act, for the three months preceding March 31, 2024, for all citations / orders assessed, not just those disclosed in the rows preceding such dollar value.

Organization and Nature of Business	Mar. 31, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Business	Organization and Nature of Business The Company was incorporated in July 2011 and is headquartered in Yardley, Pennsylvania. The Company primarily operates as a fully integrated frac and industrial sand supply and services company. The Company offers complete mine to wellsite proppant supply and logistics solutions to our frac sand customers in the oil and natural gas industry. These operations include the excavation, processing and sale of sand, or proppant, for hydraulic fracturing operations as well as proppant logistics and wellsite storage solutions through its SmartSystemsTM products and services. The Company also provides sand to customers for industrial uses through its Industrial Product Solutions (“IPS”), such as glass, foundry, building products, filtration, geothermal, renewables, ceramics, turf & landscape, retail, and recreation. Sand Mines and Processing Facilities The Company’s integrated Oakdale facility, with on-site rail infrastructure and wet and dry sand processing facilities, has access to two Class I rail lines which enable the Company to process and cost effectively deliver products to its customers. The Company commenced operations at its mine and processing facility near Oakdale, Wisconsin in July 2012, and subsequently expanded its operations in 2014, 2015 and 2018. Currently, the annual processing capacity at the Oakdale facility is approximately 5.5 million tons. In September 2020, the Company acquired two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin. The Utica facility annual processing capacity is approximately 1.6 million tons and it has access to the Burlington Northern Santa Fe Class I rail line through the Peru, Illinois transload facility. The Company began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020. The Company currently has no plans to operate the New Auburn facility for the foreseeable future. In March 2022, the Company acquired a frac sand mine and processing facility in Blair, Wisconsin. The Blair facility has approximately 2.9 million tons of total annual processing capacity and contains an onsite, unit train capable rail terminal with access to the Class 1 Canadian National Railway. The Company commenced operations at the Blair facility in April 2023. Transload & Logistics Solutions The Company also offers proppant logistics solutions to its customers through, among other things, its network of in-basin transloading terminals and its SmartSystemsTM wellsite proppant storage and management capabilities. The Company has direct access to four Class I rail lines and the ability to access all Class 1 rail lines within the United States and Canada. The Company has several in-basin rail terminals. The Company acquired rights in March 2018 to operate a unit train capable transloading terminal in Van Hook, North Dakota to service the Bakken Formation in the Williston Basin. In 2020, the Company, as part of its acquisition of the Utica, Illinois facility, obtained rights to use a rail terminal located in El Reno, Oklahoma. In September 2021, the Company acquired the rights to construct and operate a transloading terminal in Waynesburg, Pennsylvania to service the Appalachian Basin, including the Marcellus and Utica Formations, which became operational in January 2022 and then further expanded in the fourth quarter of 2023. In December 2023 and January 2024, the Company acquired rights to use transloading terminals in Minerva, Ohio and Dennison, Ohio, respectively. These terminals will service the Appalachian Basin and are expected to commence operations in the second quarter of 2024. The Company’s SmartSystems offer proppant storage solutions that create efficiencies, flexibility, enhanced safety and reliability for customers by providing the capability to unload, store and deliver proppant at the wellsite, as well as having the ability to rapidly set up, takedown and transport the entire system. The SmartDepotTM silo includes passive and active dust suppression technology, along with the capability of gravity-fed operation. The self-contained SmartPath® transloader is a mobile sand transloading system designed to work with bottom dump trailers and features a drive over conveyor, surge bin, and dust collection system. The Company has developed the SmartbeltTM a belt system to pair with its SmartPath, which allows for feeding sand directly into the hopper at the wellsite. Rapid deployment trailers are designed for quick setup, takedown and transportation of the entire SmartSystem, and they detach from the wellsite equipment, which allows for removal from the wellsite during operation. A proprietary software program, the SmartSystem TrackerTM, allows customers to monitor silo-specific information, including location, proppant type and proppant inventory.

Summary of Significant Accounting Policies	Mar. 31, 2024
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The information presented below supplements the complete description of our significant accounting policies disclosed in our 2023 Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 11, 2024. Revision of Previously Issued Financial Statements The Company has reclassified some prior year line items on its condensed consolidated statements of operations to conform to the current financial statement presentation. These reclassifications have no effect on previously reported total revenue or net income. The Company changed the names and types of revenue that are reported on each line item under revenues. Sand revenue now includes sand sales, shortfall, railcar rental, and transportation. SmartSystems revenue is primarily from the rental of our patented SmartSystems equipment and related services provided to customers. There has been no change in the manner in which we recognize revenue. Basis of Presentation and Consolidation The accompanying unaudited quarterly condensed consolidated financial statements (“interim statements”) of the Company are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore do not include all the information and notes required by GAAP. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. All adjustments are of a normal recurring nature. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. The consolidated balance sheet as of December 31, 2023 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2023. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2023. Use of Estimates The preparation of interim statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include, but are not limited to: impairment considerations of assets, including intangible assets, fixed assets, and inventory; estimated cost of future asset retirement obligations; fair value of acquired assets and assume liabilities; recoverability of deferred tax assets; inventory reserve; the collectability of receivables; and certain liabilities. Actual results could differ from management’s best estimates as additional information or actual results become available in the future, and those differences could be material. Additionally, global events such as the ongoing conflict in Ukraine and the recent conflict in the Middle East may affect oil and natural gas prices and significant volatility in the oilfield service sector. The Company is currently unable to estimate the effect of current or future events on its future financial position and results of operations. Therefore, the Company can give no assurances that these events will not have a material adverse effect on its financial position or results of operations. Employee Retention Credit The Company qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. As of March 31, 2024 and December 31, 2023, the Company included $522 in prepaid expenses and other current assets on its consolidated balance sheets related to receivables for the employee retention credits. The calculation of the credit was based on employees continued employment and represents a portion of the wages paid to them. For income tax purposes, the credit will result in decreased expense related to the wages it offsets in the period received. Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting, which updates various reportable disclosure requirements, primarily through incremental disclosures of segment expenses in both annual and interim reporting. The Update is effective for the Company as of the annual reporting period beginning January 1, 2024 and interim periods beginning January 1, 2025. While the Company is still in the process of evaluating the effects of ASU 2023-07 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect will be updated note disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes, which updates various disclosures including enhancing the income tax rate reconciliation and income taxes paid disclosures by requiring greater disaggregation of information. The other amendments in this Update are intended to improve the effectiveness and comparability of disclosures. The Update is effective for the Company for the annual reporting period beginning January 1, 2025 and for interim periods beginning January 1, 2026. While the Company is still in the process of evaluating the effects of ASU 2023-07 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect will be updated note disclosures.

Income Taxes	Mar. 31, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company calculates its interim income tax provision by estimating the annual expected effective tax rate and applying that rate to its ordinary year-to-date earnings or loss. In addition, the effect of changes in enacted tax laws, rates or tax status is recognized in the interim period in which the change occurs. For the three months ended March 31, 2024 and 2023, the effective tax rate was approximately 155.2% and (79.9)%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. For the three months ended March 31, 2024 and 2023, the statutory tax rate was 21.0%. The computation of the effective tax rate includes modifications from the statutory rate such as income tax credits, tax depletion deduction, carrybacks, and state apportionment changes, among other items. The Company has recorded a liability for uncertain tax positions included in its consolidated balance sheet of $2,240 as of December 31, 2023. There was no material change for the three months ended March 31, 2024. The Company determined that it is more likely than not that it will not be able to fully realize the benefits of certain existing deductible temporary differences and has recorded a partial valuation allowance against the gross deferred tax assets, which is included in the long-term deferred tax liabilities, net on its consolidated balance sheets. At December 31, 2023, the Company recorded a partial valuation allowance against the gross deferred tax assets on its consolidated balance sheet in the amount of $874. There was no material change for the three months ended March 31, 2024. The Company’s federal income tax returns subsequent to 2017 remain open to audit by taxing authorities. The Company has not been informed that its tax returns are the subject of any audit or investigation by taxing authorities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation In addition to the matters described below, the Company may be subject to various legal proceedings, claims and governmental inspections, audits or investigations arising out of our operations in the normal course of business, which cover matters such as general commercial, governmental and trade regulations, product liability, environmental, intellectual property, employment and other actions. Although the outcomes of these routine claims cannot be predicted with certainty, in the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on our financial statements. Cory Berg, et al. v. Hi-Crush Blair LLC, LLC et al., Case No. 2019-cv-65, Trempealeau County, Wisconsin Leland Drangstveit, et al. v. Hi-Crush Blair, LLC, et al., Case No. 2019-cv-66, Trempealeau County, Wisconsin On April 22, 2019 and September 29, 2021, Cory Berg, et al. and Leland Drangstveit, et al., respectively (collectively, the “Plaintiffs”), filed complaints and an amended complaint in separate actions against Blair, certain of its subcontractors and its and their respective insurance companies in the Circuit Court of the State of Wisconsin in and for Trempealeau County (Case Nos. 19-CV-65 and 19-CV-66, respectively). The Plaintiffs allege that Blair and its subcontractors were negligent and created a nuisance by, among other things, generating excessive noise, light and dust. The Plaintiffs are seeking unspecified monetary damages and other relief. The insurance companies included as defendants have asserted counterclaims seeking declarations as to their rights and liabilities under their respective applicable commercial general liability insurance policies. HCR has agreed under the Purchase Agreement to indemnify the Company for any actions or omissions of HCR or its affiliates (including Blair) that occurred prior to the closing of the Company’s acquisition of Blair. The cases are currently in the discovery phase and at this time, the Company is unable to express an opinion as to the likely outcome in the matter. Bonds The Company has performance bonds with various public and private entities regarding reclamation, permitting and maintenance of public roadways. Total aggregate principal amount of performance bonds outstanding as of March 31, 2024 was $19,727.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
Revision of Previously Issued Financial Statements	Revision of Previously Issued Financial Statements The Company has reclassified some prior year line items on its condensed consolidated statements of operations to conform to the current financial statement presentation. These reclassifications have no effect on previously reported total revenue or net income. The Company changed the names and types of revenue that are reported on each line item under revenues. Sand revenue now includes sand sales, shortfall, railcar rental, and transportation. SmartSystems revenue is primarily from the rental of our patented SmartSystems equipment and related services provided to customers. There has been no change in the manner in which we recognize revenue.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited quarterly condensed consolidated financial statements (“interim statements”) of the Company are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore do not include all the information and notes required by GAAP. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. All adjustments are of a normal recurring nature. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. The consolidated balance sheet as of December 31, 2023 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2023. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2023.
Use of Estimates	Use of Estimates The preparation of interim statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include, but are not limited to: impairment considerations of assets, including intangible assets, fixed assets, and inventory; estimated cost of future asset retirement obligations; fair value of acquired assets and assume liabilities; recoverability of deferred tax assets; inventory reserve; the collectability of receivables; and certain liabilities. Actual results could differ from management’s best estimates as additional information or actual results become available in the future, and those differences could be material. Additionally, global events such as the ongoing conflict in Ukraine and the recent conflict in the Middle East may affect oil and natural gas prices and significant volatility in the oilfield service sector. The Company is currently unable to estimate the effect of current or future events on its future financial position and results of operations. Therefore, the Company can give no assurances that these events will not have a material adverse effect on its financial position or results of operations.
Employee Retention Credit	Employee Retention Credit The Company qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. As of March 31, 2024 and December 31, 2023, the Company included $522 in prepaid expenses and other current assets on its consolidated balance sheets related to receivables for the employee retention credits. The calculation of the credit was based on employees continued employment and represents a portion of the wages paid to them. For income tax purposes, the credit will result in decreased expense related to the wages it offsets in the period received.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting, which updates various reportable disclosure requirements, primarily through incremental disclosures of segment expenses in both annual and interim reporting. The Update is effective for the Company as of the annual reporting period beginning January 1, 2024 and interim periods beginning January 1, 2025. While the Company is still in the process of evaluating the effects of ASU 2023-07 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect will be updated note disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes, which updates various disclosures including enhancing the income tax rate reconciliation and income taxes paid disclosures by requiring greater disaggregation of information. The other amendments in this Update are intended to improve the effectiveness and comparability of disclosures. The Update is effective for the Company for the annual reporting period beginning January 1, 2025 and for interim periods beginning January 1, 2026. While the Company is still in the process of evaluating the effects of ASU 2023-07 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect will be updated note disclosures.
