NOTE 2 — Summary of Significant Accounting Policies
The information presented below supplements the complete description of our significant accounting policies disclosed in our 2020 Form 10-K, filed with the SEC on March 3, 2021.
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 Securities and Exchange Commission 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, 2020 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2020. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2020.
Certain 2020 statement of cash flow items have been reclassified to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income.
Use of Estimates
The preparation of financial statements in accordance with GAAP 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: the sand reserves and their impact

(UNAUDITED)
on calculating the depletion expense under the units-of-production method; the depreciation and amortization associated with property, plant and equipment and definite-lived intangible assets, impairment considerations of assets (including impairment of identified intangible assets and other long-lived assets); estimated cost of future asset retirement obligations; fair value of acquired assets and assume liabilities; stock-based compensation; recoverability of deferred tax assets; inventory reserve; collectability of receivables; and certain liabilities.
Actual results could differ materially from management’s best estimates as additional information or actual results become available in the future. The decreased demand related to the coronavirus (“COVID-19”) pandemic caused dramatic swings in oil prices and significant volatility in the oilfield service sector over the last 18 months. The Company is currently unable to estimate the impact of these 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. During the three and six months ended June 30, 2021, the Company recorded $3,352 of employee retention credits in other income on its consolidated income statements and included in prepaid expenses and other current assets on the consolidated balance sheet as of June 30, 2021. The calculation of the credit is 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 June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies how companies recognize expected credit losses on financial instruments and other commitments to extend credit held by an entity at each reporting date. Existing GAAP requires an “incurred loss” methodology whereby companies are prohibited from recording an expected loss until it is probable that the loss has been incurred. ASU 2016-13 requires companies to use a methodology that reflects current expected credit losses (“CECL”) and requires consideration of a broad range of reasonable and supportable information to record and report credit loss estimates, even when the CECL is remote. Companies will be required to record the allowance for credit losses and deduct that amount from the basis of the asset and a related expense will be recognized in selling, general and administrative expenses on the income statement, similar to bad debt expense under existing GAAP. There is much latitude given to entities in determining the methodology for calculating the CECL. The guidance is effective for the Company for financial statement periods beginning after December 15, 2022, although early adoption is permitted. While the Company is still in the process of evaluating the effects of ASU 2016-13 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect, if any will be an allowance recorded against its accounts and unbilled receivables on its balance sheet and related expense on its income statement. The Company cannot determine the financial impact on its consolidated financial statements upon adoption as its accounts and unbilled receivables balances are affected by ongoing transactions with customers.
NOTE 3 — Business Combination
Eagle Proppants Holdings
On September 18, 2020, the Company entered into an Equity Purchase and Sale Agreement (the “Purchase Agreement”) with Eagle Materials Inc., a Delaware corporation (“Eagle”), pursuant to which the Company acquired all of the issued and outstanding interests in Eagle Oil and Gas Proppants Holdings LLC, a Delaware limited liability company and wholly-owned subsidiary of Eagle (“Eagle Proppants Holdings”), from Eagle for aggregate non-cash consideration of approximately $2,080. In satisfaction of the purchase price, the Company issued to Eagle 1,504 shares of its common stock; the Company issued an additional 14 shares of its common stock in January 2021 as settlement of the net working capital adjustment. The number of
10

SMART SAND, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(IN THOUSANDS, EXCEPT PER SHARE DATA)
(UNAUDITED)
shares issued was determined by the weighted average trading price of the Company’s common stock over the twenty days preceding the date of the Purchase Agreement.
In connection with the acquisition of Eagle Proppants Holdings, the Company, as borrower, also entered into a Loan Agreement with Eagle, as lender. See Note 7 - Debt, for additional information.
The primary assets of Eagle Proppants Holdings and its subsidiaries include a frac sand mine and related processing facility in Utica, Illinois and a transload facility in nearby Peru, Illinois. The Utica facility has approximately 1.6 million tons of annual processing capacity and has access to the BNSF rail line through the Peru, Illinois transload facility.
The table below presents the calculation of the total purchase consideration:

Base price consideration |  | $ | 2,000 |
20-day volume weighted average price of Smart Sand stock |  | $ | 1.33 |
Shares issued |  | 1,504 |
Closing share price on September 18, 2020 |  | $ | 1.37 |
Total equity issued |  | $ | 2,060 |
Net working capital adjustment |  | $ | 20 |
Total purchase consideration |  | $ | 2,080 |

The Company’s final allocation of the purchase price in connection with the acquisition was calculated as follows:

|  |  |  | Fair Value
Assets Acquired |  |
| Cash |  | $ | 309 |
| Accounts receivable |  | 75 |
| Inventory |  | 2,459 |
| Prepaid expenses and other current assets |  | 124 |
| Property, plant and equipment |  | 60,310 |
| Right-of-use assets |  | 9,603 |
|  | Total assets acquired |  | 72,880 |
Liabilities Assumed |  |
| Accounts payable |  | 16 |
| Accrued expenses and other liabilities |  | 2,008 |
| Asset retirement obligations |  | 8,424 |
| Operating lease liabilities |  | 9,603 |
| Deferred income taxes |  | 11,149 |
|  | Total liabilities assumed |  | 31,200 |
|  | Estimated fair value of net assets acquired |  | $ | 41,680 |

The estimated aggregate fair value of the net assets acquired was $41,680, which exceeded the total consideration and results in a bargain purchase gain of $39,600 on the acquisition date, which is included in net income for the year ended December 31, 2020. The Company believes that the seller wanted to exit the business relatively quickly and that there were a limited number of potential buyers due to the downturn in the market, which resulted in the bargain purchase gain.
The Company determined the fair values of the acquired assets and assumed liabilities based on the highest and best use of such assets as required by GAAP. Cash, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other liabilities were based on underlying assets and liabilities whose carrying value approximates fair value. The Company acquired $2,050 of contractual receivables; however, it does not expect to collect on $1,975 of such
11

SMART SAND, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(IN THOUSANDS, EXCEPT PER SHARE DATA)
(UNAUDITED)
contractual receivables as these customers are in bankruptcy proceedings. The fair value of inventory was determined using market prices the Company expected to receive for the inventory when it is sold. Operating leases were considered to be at market rates and the fair values of the associated operating lease liabilities and right-of-use assets were determined using the Company’s lease accounting policies. The fair value of the asset retirement obligations was calculated consistently with the Company’s other asset retirement obligations and includes assumptions about inflation and discount rates over time to represent the estimated future cost of dismantling, restoring and reclaiming the plant and mines in accordance with legal obligations. Deferred income taxes represent the temporary differences between future expenses for GAAP purposes and income tax purposes at the Company’s applicable enacted tax rate. The Company determined the fair values of the property, plant and equipment with the assistance of external valuation specialists. The fair value was based on the highest and best use, as required by GAAP, which was determined to be the orderly liquidation value rather than the value imputed by other valuation methods. Total acquisition costs incurred in the year ended December 31, 2020 were $891. Company’s allocation of the purchase price was complete as of December 31, 2020.

The Company recorded $10,357 of deferred revenue on the balance sheet on December 31, 2020, of which $4,194 has been recognized in the six months ended June 30, 2021. Of the remaining amount, the Company expects to recognize $2,681 through December 31, 2021 and the remainder through 2023.
NOTE 11 — Earnings Per Share
Basic net (loss) income per share of common stock is computed by dividing net loss 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 (loss) income per share of common stock is computed by dividing the net (loss) 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 restricted stock outstanding during the period calculated in accordance with the treasury stock method, although restricted stock is excluded if their effect is anti-dilutive. Because the impact of these items is anti-dilutive during periods of net loss, there was no difference between basic and diluted net loss per share of common stock for the three and six months ended June 30, 2021. Because their effect would be anti-dilutive, 2,253 shares of common stock underlying equity-based awards were excluded from the calculation of diluted earnings per share for both three and six months ended June 30, 2020. There is no reconciliation between weighted average common shares outstanding and diluted weighted average shares of common stock outstanding for any period presented.
NOTE 12 — Stock-Based Compensation
Equity Incentive Plan
In November 2016, in connection with its initial public offering, the Company adopted the 2016 Omnibus Incentive Plan (“2016 Plan”) which provides for the issuance of Awards (as defined in the 2016 Plan) of up to a maximum of 3,911 shares of the Company’s common stock to employees, non-employee members of the Board and consultants of the Company. On April 3, 2020, the Company’s board of directors adopted an amendment to the 2016 Plan to increase the available shares of common stock authorized for issuance by an additional 2,088 shares. On July 27, 2021, the Company’s board of directors authorized 231 shares currently held in treasury stock for issuance under the 2016 Plan. During the six months ended June 30, 2021 and 2020, 14 and 0 shares of restricted stock were issued under the Plans, respectively. The grant date fair value per share of all the outstanding restricted stock was $2.44 - $7.79. The shares vest over one to four years from their respective grant dates.

Overview
The Company
We are a fully integrated frac sand supply and services company, offering complete mine to wellsite proppant supply and logistics solutions to our customers. We produce low-cost, high quality Northern White frac sand, which is a premium proppant used to enhance hydrocarbon recovery rates in the hydraulic fracturing of oil and natural gas wells. We also offer proppant logistics solutions to our customers through our in-basin transloading terminal and our SmartSystems TM wellsite proppant storage capabilities. We market our products and services, as one operating segment, primarily to oil and natural gas exploration and production companies and oilfield service companies. We sell our sand under a combination of contract and spot sales in the open market, and 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, the size and favorable geologic characteristics of our sand reserves, the strategic location and logistical advantages of our facilities, our proprietary SmartDepot TM portable wellsite proppant storage silos, SmartPath TM transloader, and the industry experience of our senior management team make us as a highly attractive provider of frac sand and proppant logistics services from the mine to the wellsite.
We incorporated in Delaware in July 2011 and began operations with 1.1 million tons of annual processing capacity in July 2012. After several expansions and an acquisition, our current operational annual processing capacity is approximately 7.1 million tons of frac sand. Our mine and related processing facility near Oakdale, Wisconsin, at which we have approximately

(UNAUDITED)
315 million tons of proven recoverable sand reserves as of December 31, 2020, has approximately 5.5 million tons of annual processing capacity. This integrated facility, with on-site rail infrastructure and wet and dry sand processing facilities, has onsite access to the Canadian Pacific Class I rail line and access to the Union Pacific Class I rail line through the Byron, Wisconsin transload facility located nearby. Our mine and processing facility in Utica, Illinois, has approximately 130 million tons of proven and probable sand reserves as of December 31, 2020, and has approximately 1.6 million tons of annual processing capacity. This facility has access to the BNSF Class I rail line through the Peru, Illinois transload facility located nearby. We began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020.
We operate a unit train capable transloading terminal in Van Hook, North Dakota to service the Bakken Formation in the Williston Basin. We operate this terminal under a long-term agreement with Canadian Pacific Railway to service the Van Hook terminal directly along with the other key oil and natural gas exploration and production basins of North America. We provide Northern White sand in-basin at this terminal, which allows us to offer more efficient delivery options to customers operating in the Bakken Formation in the Williston Basin.
We also 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, 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, and we believe the system has the ability to keep up with any hydraulic fracturing operation. 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.
Business Combination
On September 18, 2020, we acquired Eagle Oil and Gas Proppants Holdings LLC (“Eagle Proppants Holdings”), for aggregate consideration of approximately $2.1 million. The estimated aggregate fair value of the net assets acquired was $41.7 million, which exceeded the total consideration and resulted in a bargain purchase gain of $39.6 million on the acquisition date.
The Utica, Illinois mining and processing assets were idle at the date of acquisition; we started mining and selling sand out of this location in the fourth quarter of 2020.
Market Trends
Our historical results of operations and cash flows are not indicative of results of operations and cash flows to be expected in the future.
In recent years, the increasing supply of sand, particularly in-basin sand, relative to demand, has led to a continued depression of frac sand prices. During most of 2020, demand for frac sand declined significantly as a result of decreased demand for oil 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 the first half of 2021 as the global distribution of COVID-19 vaccines ramped up and travel restrictions lessened. We have seen an increase in the volume of sand sold since the global economy began reopening, however the prices of frac sand have continued to be depressed and we cannot predict when frac sand prices will increase or stabilize.
Northern White frac 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 anticipate 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 frac sand. In particular, we believe that Northern White frac sand has logistical advantages in the Marcellus, Bakken, and western basins of Colorado and

Wyoming. 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. Finally, we believe that the adoption of our SmartSystems in the marketplace, which has a smaller footprint on customer sites than other solutions, will allow us to sell more sand when packaged with our last mile solutions.

Revenues
Revenues were $29.6 million for the three months ended June 30, 2021, during which time we sold approximately 767,000 tons of sand. Revenues for the three months ended June 30, 2020 were $26.1 million, during which time we sold approximately 208,000 tons of sand. The key factors contributing to the increase in revenues for the three months ended June 30, 2021 as compared to the three months ended June 30, 2020 were as follows:
•Sand sales revenue increased from $7.4 million for the three months ended June 30, 2020 to $28.8 million for the three months ended June 30, 2021 as a result of higher total volumes sold. The volumes sold during the second quarter of 2020 were negatively impacted by depressed oil prices driven by oversupply relative to the decreased demand due to the COVID-19 coronavirus pandemic. Sand sales during the second quarter of 2021 were negatively impacted by the continued depression of frac sand prices due to oversupply.
•We had no contractual shortfall revenue for the three months ended June 30, 2021 compared to $14.0 million of contractual shortfall revenue for the three months ended June 30, 2020. Our customer contracts dictate whether
24

(UNAUDITED)
shortfall is earned quarterly or at the end of their respective contract year. We recognize revenue to the extent of the unfulfilled minimum contracted quantity at the shortfall price per ton as stated in the contract.
•Logistics revenue, which includes freight for certain mine gate sand sales, railcar usage, logistics services, and SmartSystems rentals, was approximately $0.8 million for the three months ended June 30, 2021 compared to $4.7 million for the three months ended June 30, 2020. The decrease in logistics revenue was due to the shift of sales to more in-basin shipments, which includes transportation and any other handling services, rather than mine gate shipments.
Cost of Goods Sold
Cost of goods sold was $32.0 million and $11.9 million for the three months ended June 30, 2021 and 2020, respectively. The increase was primarily due to higher volumes sold and increased freight cost due to the shift of sales to more in-basin deliveries. During the second quarter of 2020, headcount reductions and other cost savings measures were implemented as a result of the onset of COVID-19. Headcount has since increased to support the increased sales activity, though the Company remains focused on other cost-saving measures.
Gross Profit
Gross profit was $(2.4) million for the three months ended June 30, 2021, compared to $14.2 million for the three months ended June 30, 2020. The decline in profitability for the three months ended June 30, 2021 as compared to the three months ended June 30, 2020 was primarily due to decreased shortfall revenue and lower average sales price of our sand.
Operating Expenses
Operating expenses were $26.3 million and $5.5 million for the three months ended June 30, 2021 and 2020, respectively. We recorded $19.6 million as non-cash bad debt expense in the current period, which is the difference between the $54.6 million accounts receivable balance that was subject to litigation and the $35.0 million cash payment received under the Settlement Agreement and Release, dated as of June 28, 2021 (the “Settlement Agreement”), by and between the Company and U.S. Well Services, LLC (“U.S. Well”). Salaries, benefits and payroll taxes were relatively consistent at $2.3 million for the three months ended June 30, 2021 as compared to $2.2 million for the three months ended June 30, 2020. Depreciation and amortization was also relatively consistent at $0.5 million for the three months ended June 30, 2020 as compared to $0.6 million for the three months ended June 30, 2021. Selling, general and administrative expenses increased from $2.9 million for the three months ended June 30, 2020 to $3.9 million for the three months ended June 30, 2021, primarily due to costs related to our newly acquired Illinois operating facilities and headcount increases compared to the prior period, which included reduced headcount and salaries for all employees due to COVID-19.
Other Income
We qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. During the three months ended June 30, 2021, the Company recorded $3.4 million of employee retention credits. The calculation of the credit is 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. We expect to continue to qualify for the employee retention credit for approximately $1.7 million for each of the remaining quarters of 2021.
Interest Expense
We incurred $0.5 million and $0.6 million of net interest expense for the three months ended June 30, 2021 and 2020, respectively. The decrease in interest expense for the three months ended June 30, 2021 was primarily due to lower total debt outstanding.
Income Tax Expense
For the three months ended June 30, 2021 and 2020, our effective tax rate was approximately (6.0)% and 42.8%, 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. We recorded a liability of $2.7 million for uncertain tax positions included in
25

deferred tax liabilities, long-term, net on our balance sheet as of June 30, 2021, related to our depletion deduction methodology, and a corresponding increase to the income tax expense on our condensed consolidated income statements for the three months ended June 30, 2021.
Net (Loss) Income
Net loss was $(27.3) million for the three months ended June 30, 2021 as compared to net income of $4.6 million for the three months ended June 30, 2020. The difference was primarily due to non-cash bad debt expense recorded against the residual balance of accounts receivable that were previously the subject of litigation combined with lower average sale prices per ton of our sand and $14.0 million less shortfall revenue in the current period.

Revenues
Revenues were $57.1 million for the six months ended June 30, 2021, during which time we sold approximately 1,527,000 tons of sand. Revenues for the six months ended June 30, 2020 were $73.6 million, during which time we sold approximately 964,000 tons of sand. The key factors contributing to the decrease in revenues for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020 were as follows:

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)
•Sand sales revenue increased from $38.4 million for the six months ended June 30, 2020 to $51.9 million for the six months ended June 30, 2021 as a result of higher total volumes sold, partially offset by lower prices compared to the prior period. The volumes sold during the second quarter of 2020 were negatively impacted by depressed oil prices driven by the oversupply caused by decreased demand due to the COVID-19 coronavirus pandemic.
•We had $1.7 million of contractual shortfall revenue for the six months ended June 30, 2021 compared to $15.3 million of contractual shortfall revenue for the six months ended June 30, 2020. Our customer contracts dictate whether shortfall is earned quarterly or at the end of their respective contract year. We recognize revenue to the extent of the unfulfilled minimum contracted quantity at the shortfall price per ton as stated in the contract.
•Logistics revenue, which includes freight for certain mine gate sand sales, railcar usage, logistics services, and SmartSystems rentals, was approximately $3.4 million for the six months ended June 30, 2021 compared to $19.9 million for the six months ended June 30, 2020. The decrease in logistics revenue was due to the shift of sales to more in-basin shipments, which includes transportation and any other handling services, rather than mine gate shipments.
Cost of Goods Sold
Cost of goods sold was $64.4 million and $53.0 million for the six months ended June 30, 2021 and June 30, 2020, respectively. The increase was primarily due to higher volumes sold and increased freight cost due to the shift of sales to more in-basin deliveries. During the second quarter of 2020, headcount reductions and other cost savings measures were implemented as a result of the onset of COVID-19. Headcount has increased in the first six months of 2021 to support increased sales activity, though the Company remains focused on other cost-saving measures.
Gross Profit
Gross profit was $(7.3) million and $20.6 million for the six months ended June 30, 2021 and June 30, 2020, respectively. The decline in profitability for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020 was primarily due to decreased shortfall revenue and lower average sales price of our sand.
Operating Expenses
Operating expenses were $32.4 million and $11.4 million for the six months ended June 30, 2021 and June 30, 2020, respectively. We recorded $19.6 million as non-cash bad debt expense, which is the difference between the $54.6 million accounts receivable balance that was subject to litigation and the $35.0 million cash payment received under the Settlement Agreement. Salaries, benefits and payroll taxes were reduced to $4.7 million for the three months ended June 30, 2021 as compared to $5.1 million for the six months ended June 30, 2020. Depreciation and amortization increased from $0.9 million for the six months ended June 30, 2020 to $1.1 million for the six months ended June 30, 2021, primarily as a result of the addition of the Illinois operating facilities acquired in September 2020. Selling, general and administrative expenses were $7.0 million for the six months ended June 30, 2021 compared to $6.5 million for the six months ended June 30, 2020. The six months ended June 30, 2020 included a $1.0 million gain on contingent consideration.
Other Income
We qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. During the six months ended June 30, 2021, the Company recorded $3.4 million of employee retention credits. The calculation of the credit is 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. We expect to continue to qualify for the employee retention credit for approximately $1.7 million for each of the remaining quarters of 2021.
Interest Expense
We incurred $1.1 million of net interest expense for each of the six months ended June 30, 2021 and June 30, 2020, respectively.

Income Tax (Benefit) Expense
For the six months ended June 30, 2021 and June 30, 2020, our effective tax rate was approximately 16.0% and 44.4%, 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. We recorded a liability of $2.7 million for uncertain tax positions included in deferred tax liabilities, long-term, net on our balance sheet as of June 30, 2021, related to our depletion deduction methodology, and a corresponding increase to the income tax expense on our condensed consolidated income statements for the six months ended June 30, 2021.
Net (Loss) Income
Net loss was $(31.2) million for the six months ended June 30, 2021 as compared to the net income of $4.6 million for the six months ended June 30, 2020. The difference was primarily due to non-cash bad debt expense recorded against the residual balance of accounts receivable that were previously the subject of litigation combined with lower average sale prices per ton of our sand and substantially lower shortfall revenue 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 costs 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.

Contribution margin was $3.5 million and $19.3 million, or $4.55 and $92.62 per ton sold, for the three months ended June 30, 2021 and 2020, respectively. The decrease in contribution margin and contribution margin per ton was due primarily to $14.0 million higher shortfall revenue in the prior period and lower average sale prices of our sand recognized in the current period.
Contribution margin was $4.5 million and $30.8 million, or $2.96 and $31.92 per ton sold, for the six months ended June 30, 2021 and 2020, respectively. The decrease in overall contribution margin and contribution margin per ton was due primarily to $13.6 million higher shortfall revenue in the prior period and lower average sale prices of our sand recognized 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.

____________________
Adjusted EBITDA was $(21.5) million for the three months ended June 30, 2021 compared to $15.6 million for the three months ended June 30, 2020. The decrease in Adjusted EBITDA for the three months ended June 30, 2021, as compared to the corresponding period in the prior year, was primarily due to non-cash bad debt expense of $19.6 million in the current period related to collecting less than the amount recorded as a receivable from the settlement of litigation, $14.0 million less shortfall revenue in the current period and lower average sale prices of our sand recognized despite having higher overall volumes in the current period.
Adjusted EBITDA was $(25.0) million for the six months ended June 30, 2021 compared to $22.0 million for the six months ended June 30, 2020. The decrease in Adjusted EBITDA for the six months ended June 30, 2021, as compared to the corresponding period in the prior year, was primarily due to $19.6 million of non-cash bad debt expense in the current period related to collecting less than the amount recorded as a receivable from the settlement of litigation, $13.6 million less shortfall revenue in the current period and lower average sale prices of our sand recognized despite having higher overall volumes in the current period.
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.

Purchases of property, plant and equipment | (2,830) |  |  | (2,238) |  |  | (5,043) |  |  | (6,423) |
Free cash flow | $ | 29,736 |  |  | $ | 11,543 |  |  | $ | 31,437 |  |  | $ | 19,419 |

Free cash flow was $29.7 million for the three months ended June 30, 2021 compared to $11.5 million for the three months ended June 30, 2020. The increase in free cash flow was primarily attributable to cash collections from customers, including the $35.0 million cash payment received under the Settlement Agreement, offset by lower average sale prices of our sand recognized in the three months ended June 30, 2021 compared to the three months ended June 30, 2020.
Free cash flow was $31.4 million for the six months ended June 30, 2021 compared to $19.4 million for the six months ended June 30, 2020. The increase in free cash flow was primarily attributable to cash collections from customers, including the $35.0 million cash payment received under the Settlement Agreement, offset by lower average sale prices of our sand recognized in the six months ended June 30, 2021 compared to the six months ended June 30, 2020. Capital expenditures for the six months ended June 30, 2021, compared to the same period in 2020, were lower as we continue to focus on maintaining positive cash flow.
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, 2021, cash on hand was $39.3 million and we had $12.9 million in undrawn availability on our ABL Credit Facility and $5.0 million in undrawn availability on the Acquisition Liquidity Support 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, including continued investment in our SmartSystems wellsite proppant storage solutions and other capital projects.

Working Capital
Working capital is a measure of our ability to pay our liabilities as they become due. The following table presents the components of our working capital as of June 30, 2021 compared to December 31, 2020.

| June 30, 2021 |  | December 31, 2020

Total current liabilities | 34,585 |  |  | 37,263 |
Working capital | $ | 47,081 |  |  | $ | 74,823 |

Our working capital was $47.1 million at June 30, 2021 compared to $74.8 million at December 31, 2020. The decrease in working capital was primarily due to the removal of $19.6 million of accounts receivable to non-cash bad debt expense, related to collecting less than the amount recorded as a receivable from the settlement of litigation, reduced inventory levels related to the increased sales volume activity in the quarter and a decline in profitability as frac sand prices continue to be depressed as a result of oversupply. As of December 31, 2020, $54.6 million of accounts receivable was attributable to U.S. Well and subject to ongoing litigation. The Company settled the litigation for a $35.0 million cash payment, which was collected during the second quarter of 2021.

ABL Credit Facility
In December 2019, we entered into a $20.0 million five-year senior secured asset-based credit facility with Jefferies Finance LLC. The available borrowing amount under the ABL Credit Facility as of June 30, 2021 was $14.1 million and is based on our eligible accounts receivable and inventory. As of June 30, 2021, the Company was in compliance with all covenants under the ABL Credit Facility and there were no amounts outstanding under the ABL Credit Facility, $1.2 million letters of credit and $12.9 million was available to be drawn. There were no borrowings during the three and six months ended June 30, 2021.
Oakdale Equipment Financing
In December 2019, we entered into a $23.0 million equipment financing arrangement with Nexseer, secured by substantially all of the assets at our Oakdale facility. The Oakdale Equipment Financing amortizes over 5 years and bears interest at 5.79%.
Notes Payable
We have entered into various financing arrangements secured primarily by our manufactured SmartSystems equipment. Title to the equipment is held by the financial institutions as collateral, though the equipment is included in the Company’s property plant and equipment. In June 2020, we executed a note payable to defer certain near-term minimum royalty payments. All notes payable bear interest at rates between 4.00% and 7.49%.
Acquisition Liquidity Support Facility
In connection our acquisition of Eagle Proppants Holdings, the Company, as borrower, also entered into a Loan Agreement with Eagle, as lender, secured by certain property rights and assets of the acquired business, whereby the Company may draw loans in an aggregate amount up to $5.0 million during the twelve month period ending September 18, 2021. There have been no borrowings on this facility.

Capital Requirements
We expect full year 2021 capital expenditures to be between $10 million and $12 million, which we anticipate will primarily support incremental growth in our SmartSystems products and services and maintenance and efficiency improvements at our mining facilities. These expenditures exclude any potential acquisitions. We expect to fund these capital expenditures with cash from operations, equipment financing options available to us or borrowings under the ABL Credit Facility or Acquisition Liquidity Support Facility. For the six months ended June 30, 2021, we spent approximately $5.0 million on capital expenditures.
Off-Balance Sheet Arrangements
We had outstanding performance bonds of $9.5 million and $10.0 million at June 30, 2021 and December 31, 2020, respectively.
Contractual Obligations
As of June 30, 2021, we had contractual obligations for the ABL Credit Facility, Oakdale Equipment Financing, notes payable, Acquisition Liquidity Support Facility, operating and finance leases, 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 to primarily non-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 were 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.

SMART SAND, INC.
MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)
Critical Accounting Policies and Estimates
There have been no material changes in our critical accounting policies and procedures during the six months ended June 30, 2021.
Use of Estimates
The preparation of financial statements in accordance with GAAP 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: existing sand reserves and their impact on calculating the depletion expense under the units-of-production method; depreciation and amortization associated with property, plant and equipment and definite-lived intangible assets; impairment considerations of assets (including impairment of identified intangible assets and other long-lived assets); estimated cost of future asset retirement obligations; fair values of acquired assets and assumed liabilities; stock-based compensation; recoverability of deferred tax assets; inventory reserve; 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 COVID-19 pandemic caused a significant amount of volatility in the oilfield services sector during 2020 and frac sand prices in particular have remained depressed, despite recent increases in oil prices. We continue to actively monitor the global impact of current events, but we are currently unable to estimate the impact of these events on our future financial position and results of operations.

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 (“OSHA”) 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. We also adhere to NISA’s respiratory protection program, and ensures that workers are provided with fitted respirators and ongoing radiological monitoring.
Our operations are subject to the Federal Mine Safety and Health Act of 1977, as amended by the Mine Improvement and New Emergency Response Act of 2006, which imposes stringent health and safety standards on numerous aspects of mineral extraction and processing operations, including the training of personnel, operating procedures, operating equipment, and other matters. Our failure to comply with such standards, or changes in such standards or the interpretation or enforcement thereof, could have a material adverse effect on our business and financial condition or otherwise impose significant restrictions on our ability to conduct mineral extraction and processing operations. Following passage of The Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the numbers of citations and orders charged against mining operations. The dollar penalties assessed for citations issued has also increased in recent years. Information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K (17 CFR 229.104) is included in Exhibit 95.1 to this Report.
ITEM 5. OTHER INFORMATION
None.
