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, the Canadian Pacific Railway through its onsite rail terminal and the Union Pacific Railway through its nearby Byron, Wisconsin facility. 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. 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 annual processing capacity at the Utica, Illinois facility is approximately 1.6 million tons and it has access to the Class I Burlington Northern Santa Fe railway 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 annual processing capacity at the Blair facility is approximately 2.9 million tons 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. Its network of terminal and rail line access enables the Company to provide cost-effective delivery options to its customers.
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 was 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. The Minerva terminal became operational in the second quarter of 2024 and the Dennison terminal became operational in the third 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 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 June 30, 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.

VFI Equipment Financing
On June 28, 2024, the Company entered into an equipment financing arrangement with VFI with a principal amount of $10,000. The VFI Equipment Financing is legally comprised of a Master Lease Agreement and one lease schedule. The VFI Equipment Financing is considered a lease under article 2A of the Uniform Commercial Code but is considered a financing arrangement for accounting and financial reporting purposes, and not a lease. The collateral under the VFI Equipment Financing includes the majority of the Company’s SmartSystems equipment. The VFI Equipment Financing bears interest at a fixed rate of 8.56%. The Company used the net proceeds to repay in full and terminate the Oakdale Equipment Financing, and the remainder was added to working capital. The VFI Equipment Financing matures on May 8, 2028.

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 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 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 right to operate a terminal in Dennison, Ohio. The Minerva terminal became operational in the second quarter of 2024 and the Dennison terminal became operational in the third quarter of 2024. We also have the right 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 provide us with 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 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, going forward, 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.
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 second 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 frontloaded their budgeted spending earlier in the year. Activity has improved in the first half of 2024 as customers ramped up activity based on 2024 budget plans. Pricing for sand has trended downward since the second half

of 2023 due to stabilized supply and demand. High levels of inflation led to increasing operating expenses in 2023, which have continued at increased levels through the first half 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 macroeconomic events or 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.

SMART SAND, INC.
MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

SmartSystems revenue was approximately $2.8 million for the three months ended June 30, 2024 compared to $2.3 million for the three months ended June 30, 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 $60.7 million and $62.1 million for the three months ended June 30, 2024 and 2023, respectively. The decrease in cost of goods sold for the three months ended June 30, 2024 as compared to the three months ended June 30, 2023 was primarily due to reduced costs of production on higher volumes through management’s efforts to reduce operating costs, as well as lower freight costs driven by more minegate sales and a shift in the in-basin sales locations.
Gross Profit
Gross profit was $13.1 million for the three months ended June 30, 2024, compared to $12.7 million for the three months ended June 30, 2023. The increase in profitability for the three months ended June 30, 2024 as compared to the three months ended June 30, 2023 was primarily due to higher tons sold, production cost savings and lower freight costs.
Selling, General and Administrative Expenses
Selling, general and administrative expenses decreased to $8.9 million for the three months ended June 30, 2024 compared to $9.0 million for the three months ended June 30, 2023, due to cost reduction measures put in place by management.
Interest Expense, net
We incurred $0.4 million and $0.2 million of net interest expense for the three months ended June 30, 2024 and 2023, respectively.
Income Tax Expense (Benefit)
For the three months ended June 30, 2024 and 2023, our effective tax rate was approximately 122.6% and (108.9)%, 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 June 30, 2024, we have recorded a liability for uncertain tax positions included in our balance sheet, related to our depletion deduction methodology. As of June 30, 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) Income
Net loss was $(0.4) million for the three months ended June 30, 2024 as compared to net income of $6.3 million for the three months ended June 30, 2023. Gross profit and operating income were consistent in both periods. Income taxes were the primary driver for the change in net income.

Total volumes increased by approximately 15%, however, average sand prices were lower in the first half 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.
SmartSystems revenue, was approximately $6.1 million for the six months ended June 30, 2024 compared to $4.7 million for the six months ended June 30, 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 $132.0 million and $132.8 million for the six months ended June 30, 2024 and June 30, 2023, respectively. Cost of goods sold remained relatively flat with slightly lower cost of production and reduced freight on a per ton basis due to a shift in delivery location and more tons sold at the minegate.
Gross Profit
Gross profit was $24.9 million and $24.3 million for the six months ended June 30, 2024 and June 30, 2023, respectively. The gross profit for the six months ended June 30, 2024 as compared to the six months ended June 30, 2023 was relatively consistent with 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. SmartSystems contributed more to gross profit as a result of higher utilization.
Selling, General and Administrative Expenses
Selling, general and administrative expenses decreased to $19.2 million for the six months ended June 30, 2024 compared to $19.7 million for the six months ended June 30, 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 half 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 $0.9 million and $0.7 million of net interest expense for the six months ended June 30, 2024 and June 30, 2023, respectively.
Income Tax Expense (Benefit)
For the six months ended June 30, 2024 and June 30, 2023, our effective tax rate was approximately 128.2% and (166.0)%, 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, 2024, we have recorded a liability for uncertain tax positions included on our balance sheet, related to our depletion deduction methodology. As of June 30, 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 $0.6 million for the six months ended June 30, 2024 as compared to net income of $2.7 million for the six months ended June 30, 2023. Gross profit and operating income were consistent in both periods. Income taxes were the primary driver for the change in net income.
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 $19.8 million and $19.0 million, or $15.53 and $17.57 per ton sold, for the three months ended June 30, 2024 and 2023, respectively. Contribution margin was $38.3 million and $36.8 million, or $14.67 and $16.17 per ton sold, for the six months ended June 30, 2024 and 2023, respectively. The increase in overall contribution margin for both the three and six month periods ended June 30, 2024, when compared to the same periods in 2023, was primarily due to higher tons sold and the increased utilization of our SmartSystems fleet, as well as our focus on cost reduction measures throughout the Company.
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 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.

Adjusted EBITDA was $21.2 million for the six months ended June 30, 2024 compared to $19.4 million for the six months ended June 30, 2023. The increase in adjusted EBITDA for the six months ended June 30, 2024, compared to the same period in 2023, was primarily due to higher sales volumes 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.
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
