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 Spring, Texas. 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. In late 2021, the Company created its Industrial Product Solutions (“IPS”) business in order to diversify its customer base and markets it serves by offering sand to customers for industrial uses, 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 Company’s 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 has an annual processing capacity of 1.6 million tons and 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 has no plans to operate the New Auburn facility for the foreseeable future.

In March 2022, the Company entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Hi-Crush Inc., a Delaware corporation (“HCR”), and Hi-Crush Blair LLC, a Delaware limited liability company and wholly-owned subsidiary of HCR (“Blair”), pursuant to which the Company acquired all of the issued and outstanding limited liability company interests of Blair from HCR for aggregate cash consideration of approximately $6,450, subject to customary purchase price adjustments as set forth in the Purchase Agreement (the “Transaction”).

The primary assets of Blair consisted of an idle frac sand mine and related processing facility located 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 another transloading terminal in Waynesburg, Pennsylvania to service the Appalachian Basin, including the Marcellus and Utica Formations, which became operational in January 2022.

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 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 SmartPathTM 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 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 2022 Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on February 28, 2023.

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, 2022 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2022. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2022.

Revision of Previously Issued Financial Statements for Immaterial Misstatements

During the quarter ended March 31, 2023, the Company identified a misclassification in the operating expenses section of the statement of operations in the audited financial statements for the year ended December 31, 2022. The misclassification was an overstatement of salaries, benefits and payroll taxes and an understatement of selling, general and administrative in the amount of $1,462. For the three and twelve months ended December 31, 2022, the Company has decreased salaries, benefits and payroll taxes and increased selling, general and administrative line items by $1,462. There was no effect to the amounts reported in the first, second or third quarter financial statements of 2022. Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, “Materiality”, the Company evaluated the materiality of this misclassification quantitatively and qualitatively and concluded that it was not material to any of its prior annual or quarterly financial statements or trends of financial results. The Company has reclassified the prior year financial statement presentation to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income. Additionally, certain 2022 operating expenses have been reclassified to conform to the current financial statement presentation. The reclassifications have no effect on previously reported net income.

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. The decrease in demand related to COVID-19 pandemic in 2020 and 2021 and the ongoing conflict in Ukraine have caused dramatic swings in oil and natural gas prices and significant volatility in the oilfield service sector. The Company is currently unable to estimate the impact 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 June 30, 2023 and December 31, 2022, the Company included $522 and $1,180, respectively, in prepaid expenses and other current assets on its consolidated balance sheets related to receivables for

NOTE 3 — Acquisition

Asset Acquisition - Blair Facility

On March 4, 2022, the Company entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Hi-Crush Inc., a Delaware corporation (“HCR”), and Hi-Crush Blair LLC, a Delaware limited liability company and wholly-owned subsidiary of HCR (“Blair”), pursuant to which the Company acquired all of the issued and outstanding limited liability company interest of Blair from HCR for aggregate cash consideration of $6,450, subject to customary purchase price adjustments as set forth in the Purchase Agreement (the “Transaction”).

The primary assets of Blair consisted of an idle frac sand mine and related processing facility located in Blair, Wisconsin. The Blair 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 Railway, became operational in April 2023.

The Company accounted for this transaction as an asset acquisition based on an evaluation of the guidance in ASC 805. The Company determined that there was not a substantive process in place that generates outputs that can be sold to a customer, and therefore the acquisition did not meet the definition of a business. The Company recognized identifiable assets acquired on a relative fair value basis. All assets acquired are allocated to property, plant and equipment, net on the balance sheet as of March 31, 2022. As of March 31, 2022, the Company also recorded an increase to its asset retirement obligations and a corresponding increase in purchases of property plant and equipment in the amount of $8,281 and subsequently revised the estimate to $1,988 based on its mine plan as of December 31, 2022.

The table below presents the calculation of the total purchase consideration:

NOTE 11 — Earnings Per Share

Basic net income (loss) per share of common stock is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, excluding the dilutive effects of restricted stock. Diluted net income (loss) per share of common stock is computed by dividing the net income attributable to common stockholders by the sum of the weighted-average number of shares of common stock outstanding during the period plus the potential dilutive effects of shares of restricted stock outstanding during the period calculated in accordance with the treasury stock method, although shares of restricted stock are excluded if their effect is anti-dilutive. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 3,162 and 777 for the three months ended June 30, 2023 and 2022, respectively. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 2,196 and 1,014 for the six months ended June 30, 2023 and 2022, respectively. Other periods presented below are in periods with a net loss and there was no difference between basic and diluted net loss per share of common stock. The following table reconciles the weighted-average common shares outstanding used in the calculation of basic net (loss) income per share to the weighted average common shares outstanding used in the calculation of diluted net income per share.

NOTE 12 — 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 June 30, 2023 and 2022, the effective tax rate was approximately (108.9)% and 108.7%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. For the six months ended June 30, 2023 and 2022, the effective tax rate was approximately (166.0)% and 34.1%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. For the three and six months ended June 30, 2023 and 2022, 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, 2022. There was no material change for the six months ended June 30, 2023.

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, 2022, the Company recorded a partial valuation allowance against the gross deferred tax assets on its consolidated balance sheet in the amount of $1,588.

proprietary SmartPathTM transloader, and 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 is 5.5 million tons, which has access to both the Canadian Pacific and Union Pacific rail networks. In 2020, we acquired our Utica, Illinois mine and processing facility, which has an annual processing capacity of 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 an annual processing capacity of 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.

We sell frac sand through a network of in-basin rail terminals. We directly control three 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, which has been providing Northern White Sand in-basin to our customers since the Van Hook terminal became operational in April 2018. In 2020, as part of our acquisition of the Utica, Illinois mining facility, we obtained rights to use a rail terminal located in El Reno, Oklahoma. In January 2022, we began operations at an additional unit train capable transloading terminal in Waynesburg, Pennsylvania to service the Appalachian Basin, including the Marcellus and Utica Formations.

We also offer to our customers portable wellsite 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, 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 a mobile sand transloading system designed to work with bottom dump trailers and features a drive over conveyor, surge bin, and dust collection system. We believe this system has the ability to keep up with any hydraulic fracturing operation. We have developed a belt system to pair with our SmartPath which allows feeding sand directly into the hopper at the wellsite leading to more efficient delivery of the sand into hopper. Our rapid deployment trailers are designed for quick setup, takedown and transportation of the entire SmartSystem, and detach from the wellsite equipment, which allows for removal from the wellsite during 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 meet their goals to reduce their carbon footprint in their daily operations.

In late 2021, we started our IPS business whereby we offer our sand to customers for various industrial purposes, such as glass, foundry, building products, filtration, geothermal, renewables, ceramics, turf & landscape, retail, and recreation. While we are still in the early stages of this business, we believe that as it 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.

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 most of 2020, demand for frac sand declined significantly due to decreased demand for oil and natural gas as a result of the ongoing effects of the coronavirus (“COVID-19”) pandemic, which caused a global decrease in all means of travel, the closure of borders between countries and a general slowing of economic activity worldwide. Activity in the oil and gas industry began to rebound in the fourth quarter of 2020 and through 2021 as the global distribution of COVID-19 vaccines ramped up and travel restrictions lessened. However, the prices of frac sand remained depressed during 2021 as supply remained out of balance with demand even though market activity was improving. Beginning in the first quarter of 2022 and

(UNAUDITED)

continuing through the second quarter of 2023, supply and demand fundamentals have shifted, which has led to pricing improvements in frac sand.

The ongoing conflict in Ukraine has contributed to dramatic swings in oil and natural gas prices and significant volatility in the oilfield service sector. Additionally, other economic factors, including continued high inflation and slower economic growth could lead to a global economic recession that could have a negative impact on global oil and natural gas demand, which may lead to continued volatility in the oil field service sector. We cannot predict if positive pricing trends for our products will continue, increase, decrease or stabilize.

Northern White sand, which is found predominantly in Wisconsin and limited portions of Minnesota, Illinois, and Missouri, is considered a premium proppant due to its favorable physical characteristics. While we believe that regional sand will continue to affect the demand for Northern White sand in some of the oil and natural gas producing basins in which we operate, we believe there will continue to be demand for our high-quality Northern White sand. In particular, we believe that Northern White sand has logistical advantages in the Appalachian basin, Bakken basin, and in Canada. We expect demand for our frac sand to continue to be supported by customers who are focused on long-term well performance and ultimate recovery of reserves from the oil and natural gas wells they are completing as well as those interested in the efficiency of their logistics supply chain and delivery of sand to the wellsite. Additionally, we believe market trends continue to support increased proppant usage per well drilled due to operator focus on well efficiencies through increasing lengths of drilling laterals, use of simul-fracking techniques and other well enhancement strategies. As the amount of sand per well continues to increase, we believe the delivery of sand to the operating basins by rail in bulk shipments to terminals in close proximity to drilling activity provides more sustainable and efficient delivery of sand to meet a customer’s long-term proppant needs. Finally, we believe that the adoption of our SmartSystems in the marketplace, which has a smaller footprint on customer sites than other sand storage solutions, will allow us to sell more sand when packaged with our last mile solutions. We believe the combination of our high quality Northern White sand delivered in bulk to in basin terminals and ultimately delivered to the wellsite through our SmartSystems wellsite proppant storage solutions provide our customers efficient and sustainable sand supply to the wellsite that will reduce trucking and related fuel consumption for our customers, helping them to meet their goals to reduce their carbon footprint in their daily operations.

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. While we are still in the early stages of this business, we believe that as it 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 $74.8 million and tons sold were approximately 1,084,000 for the three months ended June 30, 2023. Revenues for the three months ended June 30, 2022 were $68.7 million, during which time we sold approximately 1,196,000 tons of sand. The key factors contributing to the increase in revenues for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022 were as follows:

•Sand sales revenue increased 8% from $67.1 million for the three months ended June 30, 2022 to $72.4 million for the three months ended June 30, 2023. While tons sold were marginally lower in the current period, compared to the same period in the prior year, revenues increased as a result of an increase in higher average sales prices of our sand. Consistently strong demand for oil and natural gas has led to increased well completion activity, which has helped the demand for frac sand to remain strong.

•Logistics revenue, which is primarily SmartSystems rentals, were approximately $2.3 million for the three months ended June 30, 2023 compared to $1.6 million for the three months ended June 30, 2022. The increase in logistics revenue was due to a higher utilization of our SmartSystems fleet.

Cost of Goods Sold

Cost of goods sold was $62.1 million and $59.7 million for the three months ended June 30, 2023 and 2022, respectively. The increase was primarily due to an increase in freight costs and higher labor expenses.

Gross Profit

Gross profit was $12.7 million for the three months ended June 30, 2023, compared to $9.0 million for the three months ended June 30, 2022. The increase in profitability for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022 was primarily due to higher average sales prices of our sand relative to the cost to produce and deliver products to our customers.

Operating Expenses

Operating expenses were $9.6 million and $7.6 million for the three months ended June 30, 2023 and 2022, respectively. Salaries, benefits and payroll taxes increased to $4.4 million for the three months ended June 30, 2023 as compared to $3.2 million for the three months ended June 30, 2022, due primarily to increased wages. Depreciation and amortization remained flat at $0.6 million for the three months ended June 30, 2023 and June 30, 2022. Selling, general and administrative expenses increased to $4.6 million for the three months ended June 30, 2023 compared to $3.8 million for the three months ended June 30, 2022, primarily due to the opening of our new Blair facility.

Interest Expense, net

We incurred $0.2 million and 0.4 million of net interest expense for the three months ended June 30, 2023 and 2022, respectively.

Income Tax Expense (Benefit)

For the three months ended June 30, 2023 and 2022, our effective tax rate was approximately (108.9)% and 108.7%, 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 June 30, 2023, we have recorded a liability for uncertain tax positions included in our balance sheet, related to our depletion deduction methodology. As of June 30, 2023, 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 Income (Loss)

Net income was $6.3 million for the three months ended June 30, 2023 as compared to net loss of $0.1 million for the three months ended June 30, 2022. The improvement in net income in the current period relative to the prior period is primarily due to higher average sales prices as increased demand has caused a positive shift in sand prices, partially offset by an increase in operating expenses.

Revenues

Revenues were $157.1 million and tons sold were approximately 2,279,000 for the six months ended June 30, 2023. Revenues for the six months ended June 30, 2022 were $110.3 million, during which time we sold approximately 2,048,000 tons of sand. The key factors contributing to the increase in revenues for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022 were as follows:

•Sand sales revenue increased 43% from $105.4 million for the six months ended June 30, 2022 to $150.5 million for the six months ended June 30, 2023 as a result of an approximately 11% increase in total volumes sold and higher average sales prices for our sand. Sand prices have increased due to a shift in supply and demand, which we believe is driven by consistently strong demand for oil and natural gas wells that has led to increased well completion activity during the first half of 2023 in primary basins which we serve.

•Logistics revenue, which includes primarily SmartSystems rentals, was approximately $4.7 million for the six months ended June 30, 2023 compared to $3.0 million for the six months ended June 30, 2022. The increase in logistics revenue was due to higher utilization of our SmartSystems fleet.

Cost of Goods Sold

Cost of goods sold was $132.8 million and $103.3 million for the six months ended June 30, 2023 and June 30, 2022, respectively. The increase was primarily due to higher volumes sold in the current period and the related increase in production costs and freight costs, as well as transloading costs as more of our sales have shifted to in-basin sales.

Gross Profit

Gross profit was $24.3 million and $7.0 million for the six months ended June 30, 2023 and June 30, 2022, respectively. The increase in the gross profit for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022 was primarily due to higher sales volumes and higher average sales prices of our sand relative to the cost to produce and deliver products to our customers.

Operating Expenses

Operating expenses were $22.9 million and $15.6 million for the six months ended June 30, 2023 and June 30, 2022, respectively. Salaries, benefits and payroll taxes increased to $9.5 million for the six months ended June 30, 2023 as compared to $6.6 million for the six months ended June 30, 2022, due primarily to increased staffing to support our business. Selling, general and administrative expenses increased to $10.2 million for the six months ended June 30, 2023 compared to $7.9 million for the six months ended June 30, 2022, due primarily to a 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 as well as additional royalties, real estate taxes, maintenance, insurance expense and royalties due to the acquisition of the Blair facility.

Interest Expense, net

We incurred $0.7 million and 0.8 million of net interest expense for the six months ended June 30, 2023 and June 30, 2022, respectively.

Income Tax Benefit

For the six months ended June 30, 2023 and June 30, 2022, our effective tax rate was approximately (166.0)% and 34.1%, 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 June 30, 2023, we have recorded a liability for uncertain tax positions included on our balance sheet, related to our depletion deduction methodology. As of June 30, 2023, 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 $2.7 million for the six months ended June 30, 2023 as compared to net loss of $6.0 million for the six months ended June 30, 2022. The decrease in net loss year-over-year is primarily attributable to an increase in total volumes sold and higher average sales prices of our sand, partially offset by $1.9 million of 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 current 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 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.

Contribution margin was $19.0 million and $15.3 million, or $17.57 and $12.75 per ton sold, for the three months ended June 30, 2023 and 2022, respectively. Contribution margin was $36.8 million and $19.5 million, or $16.17 and $9.52 per ton sold, for the six months ended June 30, 2023 and 2022, respectively. The increase in overall contribution margin and contribution margin per ton for the three months ended June 30, 2023, when compared to the same period in 2022, was primarily due to higher average sales prices. The increase for the six months ended June 30, 2023, compared to the six months ended June 30, 2022, was due primarily to higher sales volumes and higher average sales prices along with increased IPS sales and higher utilization of our SmartSystems fleet in the current period.

EBITDA and Adjusted EBITDA

We define EBITDA as net income, plus: (i) depreciation, depletion and amortization expense; (ii) income tax expense (benefit); (iii) interest expense; and (iv) franchise taxes. 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 restructuring, retention and other similar actions; (vi) earn-out, contingent consideration obligations and other acquisition and development costs; 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.

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.

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.

Free cash flow	$	10,841	$	(3,656)	$	11,928	$	(22,633)

Free cash flow was $10.8 million for the three months ended June 30, 2023 compared to $(3.7) million for the three months ended June 30, 2022. Free cash flow was $11.9 million for the six months ended June 30, 2023 compared to $(22.6) million for the six months ended June 30, 2022. The increase in free cash flow for both the three months and six months ended June 30, 2023 in comparison to the same periods in 2022 was primarily attributable to positive cash flows from operating activities due higher conversion of working capital to cash as well as the acquisition of the Blair facility in the prior year.

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 June 30, 2023, cash on hand was $5.5 million and we had $19.0 million in undrawn availability on our ABL Credit 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 2023 capital expenditures, to be between $20.0 million and $25.0 million, which we anticipate will primarily support efficiency projects at our Oakdale and Utica facilities and the commencement of operations at our Blair facility. We expect to fund these capital expenditures with cash from operations, equipment financing options available to us or borrowings under the ABL Credit Facility.

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 June 30, 2023 was $9.9 million. Minimum cash payments on this facility for the remainder of 2023 are anticipated to be $2.3 million. Our various notes payable are primarily secured by our manufactured SmartSystems. Total debt under these notes payable as of June 30, 2023 was $2.1 million. Minimum cash payments on these notes payable for the remainder of 2023 are anticipated to be $0.7 million. There was no outstanding balances on our ABL Credit Facility as of June 30, 2023.

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 June 30, 2023 were $26.8 million. Minimum cash payments on operating leases for the remainder of 2023 are anticipated to be $6.1 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 14 years.

Off-Balance Sheet Arrangements

We had outstanding performance bonds of $17.3 million at June 30, 2023.

Contractual Obligations

As of June 30, 2023, we had contractual obligations for the ABL Credit Facility, Oakdale Equipment Financing, notes payable, operating and finance leases, 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, our excavation and our wet sand processing activities have historically been limited during winter months. As a consequence, we 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 overproduced 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 each 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 six months ended June 30, 2023, revenue from EQT Production Corporation, Liberty Oilfield Services, and Enerplus Resources Corporation accounted for 30.6%, 10.2% and 8.7%, respectively, of total revenue. For the six months ended June 30, 2022, EQT Production Corporation, Liberty Oilfield Services, and Encino Energy accounted for 30.6%, 10.2%, and 9.1%, respectively, of total revenue.

Critical Accounting Policies and Estimates

There have been no material changes in our critical accounting policies and procedures during the six months ended June 30, 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 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 no outstanding balance under our ABL Credit Facility as of June 30, 2023. We do not believe this represents a material interest rate risk.

We have considered other changes in our exposure to market risks during the six months ended June 30, 2023 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, 2022, filed with the SEC on February 28, 2023.

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 June 30, 2023 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 and six months ended June 30, 2023.

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, 2022.

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

During the three months ended June 30, 2023, 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 June 30, 2023, for all citations / orders assessed, not just those disclosed in the rows preceding such dollar value.

Organization and Nature of Business	6 Months Ended
Organization and Nature of Business	Jun. 30, 2023
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 Spring, Texas. 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. In late 2021, the Company created its Industrial Product Solutions (“IPS”) business in order to diversify its customer base and markets it serves by offering sand to customers for industrial uses, 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 Company’s 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 has an annual processing capacity of 1.6 million tons and 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 has no plans to operate the New Auburn facility for the foreseeable future. In March 2022, the Company entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Hi-Crush Inc., a Delaware corporation (“HCR”), and Hi-Crush Blair LLC, a Delaware limited liability company and wholly-owned subsidiary of HCR (“Blair”), pursuant to which the Company acquired all of the issued and outstanding limited liability company interests of Blair from HCR for aggregate cash consideration of approximately $6,450, subject to customary purchase price adjustments as set forth in the Purchase Agreement (the “Transaction”). The primary assets of Blair consisted of an idle frac sand mine and related processing facility located 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 another transloading terminal in Waynesburg, Pennsylvania to service the Appalachian Basin, including the Marcellus and Utica Formations, which became operational in January 2022. 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 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 SmartPathTM 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 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	Jun. 30, 2023
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 2022 Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on February 28, 2023. 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, 2022 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2022. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2022. Revision of Previously Issued Financial Statements for Immaterial Misstatements During the quarter ended March 31, 2023, the Company identified a misclassification in the operating expenses section of the statement of operations in the audited financial statements for the year ended December 31, 2022. The misclassification was an overstatement of salaries, benefits and payroll taxes and an understatement of selling, general and administrative in the amount of $1,462. For the three and twelve months ended December 31, 2022, the Company has decreased salaries, benefits and payroll taxes and increased selling, general and administrative line items by $1,462. There was no effect to the amounts reported in the first, second or third quarter financial statements of 2022. Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, “Materiality”, the Company evaluated the materiality of this misclassification quantitatively and qualitatively and concluded that it was not material to any of its prior annual or quarterly financial statements or trends of financial results. The Company has reclassified the prior year financial statement presentation to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income. Additionally, certain 2022 operating expenses have been reclassified to conform to the current financial statement presentation. The reclassifications have no effect on previously reported net income. 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. The decrease in demand related to COVID-19 pandemic in 2020 and 2021 and the ongoing conflict in Ukraine have caused dramatic swings in oil and natural gas prices and significant volatility in the oilfield service sector. The Company is currently unable to estimate the impact 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 June 30, 2023 and December 31, 2022, the Company included $522 and $1,180, respectively, 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 There are no recent accounting pronouncements that materially affect the financial statements of the Company.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per ShareBasic net income (loss) per share of common stock is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, excluding the dilutive effects of restricted stock. Diluted net income (loss) per share of common stock is computed by dividing the net income attributable to common stockholders by the sum of the weighted-average number of shares of common stock outstanding during the period plus the potential dilutive effects of shares of restricted stock outstanding during the period calculated in accordance with the treasury stock method, although shares of restricted stock are excluded if their effect is anti-dilutive. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 3,162 and 777 for the three months ended June 30, 2023 and 2022, respectively. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share as their effect would be anti-dilutive was 2,196 and 1,014 for the six months ended June 30, 2023 and 2022, respectively. Other periods presented below are in periods with a net loss and there was no difference between basic and diluted net loss per share of common stock. The following table reconciles the weighted-average common shares outstanding used in the calculation of basic net (loss) income per share to the weighted average common shares outstanding used in the calculation of diluted net income per share.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2023
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 June 30, 2023 and 2022, the effective tax rate was approximately (108.9)% and 108.7%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. For the six months ended June 30, 2023 and 2022, the effective tax rate was approximately (166.0)% and 34.1%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. For the three and six months ended June 30, 2023 and 2022, 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, 2022. There was no material change for the six months ended June 30, 2023. 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, 2022, the Company recorded a partial valuation allowance against the gross deferred tax assets on its consolidated balance sheet in the amount of $1,588.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2023
Accounting Policies [Abstract]
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, 2022 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2022. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2022.
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. The decrease in demand related to COVID-19 pandemic in 2020 and 2021 and the ongoing conflict in Ukraine have caused dramatic swings in oil and natural gas prices and significant volatility in the oilfield service sector. The Company is currently unable to estimate the impact 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements There are no recent accounting pronouncements that materially affect the financial statements of the Company.
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 June 30, 2023 and December 31, 2022, the Company included $522 and $1,180, respectively, 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.
Reclassification	Revision of Previously Issued Financial Statements for Immaterial Misstatements During the quarter ended March 31, 2023, the Company identified a misclassification in the operating expenses section of the statement of operations in the audited financial statements for the year ended December 31, 2022. The misclassification was an overstatement of salaries, benefits and payroll taxes and an understatement of selling, general and administrative in the amount of $1,462. For the three and twelve months ended December 31, 2022, the Company has decreased salaries, benefits and payroll taxes and increased selling, general and administrative line items by $1,462. There was no effect to the amounts reported in the first, second or third quarter financial statements of 2022. Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, “Materiality”, the Company evaluated the materiality of this misclassification quantitatively and qualitatively and concluded that it was not material to any of its prior annual or quarterly financial statements or trends of financial results. The Company has reclassified the prior year financial statement presentation to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income. Additionally, certain 2022 operating expenses have been reclassified to conform to the current financial statement presentation. The reclassifications have no effect on previously reported net income.
