#1Investor Presentation - November 2023 smartsand® Mine to Wellsite Solutions®#2Disclaimer Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the federal securities laws. Statements that are predictive in nature, that depend upon or refer to future events or conditions or that include the words "believe," "expect," "anticipate," "intend," "estimate" and other expressions that are predictions of or indicate future events and trends and that do not relate to historical matters identify forward- looking statements. Our forward-looking statements include statements about our business strategy, our industry, our future profitability, our expected capital expenditures and the impact of such expenditures on our performance, the costs of being a publicly traded corporation and our capital programs. A forward-looking statement may include a statement of the assumptions or bases underlying the forward-looking statement. We believe that we have chosen these assumptions or bases in good faith and that they are reasonable. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include, but are not limited to (i) large or multiple customer defaults, including defaults resulting from actual or potential insolvencies, (ii) the level of production of crude oil, natural gas and other hydrocarbons and the resultant market prices of crude oil, natural gas, natural gas liquids and other hydrocarbons, (iii) changes in general economic and geopolitical conditions; (iv) competitive conditions in our industry (including the adoption of regional sand), (v) changes in the long-term supply of and demand for oil and natural gas, (vi) actions taken by our customers, competitors and third-party operators, (vii) changes in the availability and cost of capital, (viii) our ability to successfully implement our business plan, (ix) our ability to complete growth projects on time and on budget, (x) the price and availability of debt and equity financing (including changes in interest rates), (xi) changes in our tax status, (xii) technological changes, (xiii) operating hazards, natural disasters, pandemics, weather-related delays, casualty losses and other matters beyond our control, (xiv) the effects of existing and future laws and governmental regulations (or the interpretation thereof), (xv) our ability to collect our accounts receivable, (xvi) the effects of litigation, and such other factors discussed or referenced in the "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of the Form 10-K for the year ended December 31, 2022, as well as subsequent reports on Form 10-Q, all of which have been filed by the Company with the U.S. Securities and Exchange Commission (the "SEC") and are available at www.sec.gov. You should not place undue reliance on our forward-looking statements. Although forward-looking statements reflect our good faith beliefs at the time they are made, forward-looking statements involve known and unknown risks, uncertainties and other factors, including the factors described in the preceding paragraph, which may cause our actual results, performance or achievements to differ materially from anticipated future results, performance or achievements expressed or implied by such forward-looking statements. You should also carefully consider the statements under the heading "Disclaimer Regarding Forward-looking Statements and Risk Factor Summary" in the Annual Report on Form 10-K for the year ended December 31, 2022. Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise, unless required by law. In this presentation, assumptions were made with respect to industry performance, general business and economic conditions and other matters. Any estimates contained in these analyses, whether expressed or implied, are based on estimates and are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth herein. The Company reserves the right to change any or all of the estimates included herein whether as a result of any changes in the above referenced information, market factors or otherwise. Industry and Market Data This presentation has been prepared by the Company and includes market data and other statistical information from third-party sources, including independent industry publications, or other published independent sources. Although the Company believes these third-party sources are reliable as of their respective dates, the Company has not independently verified the accuracy or completeness of this information. smartsand® Mine to Wellsite Solutions®#3Disclaimer (cont'd) Reserves This presentation includes frac sand reserve and resource estimates based on engineering, economic and geological data assembled, analyzed and periodically reviewed by the Company and its outside consultants. However, frac sand reserve estimates are by nature imprecise and depend to some extent on statistical inferences drawn from available data, which may prove unreliable. There are numerous uncertainties inherent in estimating quantities and qualities of frac sand reserves and non-reserve frac sand deposits and costs to mine recoverable reserves, many of which are beyond our control and any of which could cause actual results to differ materially from our expectations. These uncertainties include: geological and mining conditions that may not be fully identified by available data or that may differ from experience; assumptions regarding the effectiveness of our mining, quality control and training programs; assumptions concerning future prices of frac sand, operating costs, mining technology improvements, development costs and reclamation costs; and assumptions concerning future effects of regulation, including the issuance of required permits and taxes by governmental agencies. Non-GAAP Information This presentation also contains information about the Company's contribution margin, EBITDA, Adjusted EBITDA, and free cash flow which are not measures derived in accordance with U.S. generally accepted accounting principles ("GAAP") and which exclude components that are important to understanding the Company's financial performance. 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. Gross profit is the GAAP measure most directly comparable to contribution margin. We believe contribution margin is a meaningful measure because it provides an operating and financial measure of our ability to generate margin in excess of our operating cost base. We define EBITDA as our 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, (vii) non-cash charges and unusual or non-recurring charges. 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. 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. 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 on these non-GAAP financials measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. smartsand® Mine to Wellsite Solutions®#4Company Highlights The Right Operating Model High quality Northern White Sand mining and processing facilities located on Class 1 rail lines " Oakdale, WI: 247 million tons of reserves, 5.5 million tons of annual processing capacity, unit train capable access to CP and UP rail lines Utica, IL: 128 million tons of reserves, 1.6 million tons of annual processing capacity, unit train capable access to BNSF rail line Blair, WI: 115 million tons of reserves, 2.9 million tons of annual processing capacity, unit train capable access to CN rail line Low operating cost structure Mining, processing, and shipping primarily done in close proximity to ensure efficient and low-cost operations Large single mine sites on rail dominate other bulk commodity business models Sustainable long-term supply and logistics advantage Combination of large, high quality reserve base, low-cost operations, and ability to ship large quantities of sand efficiently and sustainably to all operating basins Company controlled terminals at Van Hook, ND, Waynesburg, PA and El Reno, OK coupled with network of third-party terminal partners SmartSystemsTM wellsite storage solutions Ability to leverage existing assets to support diversification into Industrial Products Solutions Existing reserve base and processing locations well positioned to support sales sinto the Industrial Products market The Right Sand On a combined basis, the majority of the reserves at our operating mines are fine mesh (40/70 and 100 Mesh) Fine mesh frac sand represents over 80% of the current demand for frac sand Quality Matters (40/70 Northern White Sand vs in-basin Sand is a higher quality product that we believe can lead to better long-term well results for oil and gas producers The Right Capital Structure/Focus on Long Term Shareholder Value Prudent capital structure with lowest leverage levels in the proppant industry High insider ownership that aligns management with investors (~17% owned by CEO, ~31% owned by insiders) Repurchased 11.3% of common shares outstanding in February 2023 from an affiliate of Clearlake Capital Group Strong Sales Volumes, Contribution Margin and Adjusted EBITDA over last several quarters smartsand® Mine to Wellsite Solutions®#5Company Overview 5#6Smart Sand is a Fully Integrated Provider of Mine to Wellsite Solutions Premium Northern White Reserve Gigantic Rail Capacity Smart Sand's Business Offerings Terminal & Forward Staging Management Last Mile Logistics Wellsite Storage Solutions Large Finer Mesh Northern White Reserve Consistent high-quality proppant Up to approximately 10 million tons annual production capability Class 1 rail (CP, UP, BNSF, CN) Planning ahead reduces risks Unit train capable logistics facilities at all mine locations Redundancy in the supply chain Avoid trucking congestion Safe and reliable Helps eliminate demurrage Smaller fleet and more turns per day Wellsite storage Direct to the blender delivery Realtime inventory control smartsand® Mine to Wellsite Solutions®#7Summary Financials Quarterly Sales Volumes (thousands of tons) 1,175 1,195 1,219 1,110 1,084 Quarterly Revenue ($ in millions) $82.4 $76.9 $74.8 $73.8 $71.6 Q3 '22 Q4'22 Q1'23 Q2 '23 Q3 '23 Q3'22(1) Q4'22(2) Q1'23(3) Q2'23 Q3'23(4) Contribution Margin/Ton $16.01 Q3'22 $14.89 $14.77 Q4'22 Q1'23 (1) (2) (3) (4) Includes monthly minimum / shortfall payments of $2.7 million for 3Q '22 Includes monthly minimum / shortfall payments of $0.4 million for 4Q '22 Includes monthly minimum / shortfall payments of $1.9 million for 1Q '23 Includes monthly minimum / shortfall payments of $2.4 million for 3Q '23 $17.57 $17.20 Quarterly Adjusted EBITDA ($ in millions) $13.3 $11.3 $10.7 $11.4 $8.4 Q2'23 Q3'23 Q3'22 Q4'22 Q1'23 Q2'23 Q3'23 7 smartsandⓇ Mine to Wellsite Solutions®#8Market Overview 8#9Industry Trends Continue to Support Increasing Levels of Frac Sand Demand Hydraulic Fracturing Sand per Frac Spread 250 200 150 MILLIONS OF POUNDS OF SAND PER SPREAD 100 50 0 Q2 20 Q1 20 Q4 19 Q3 19 Q2 19 Q1 19 Q4 18 Q3 18 Q2 18 Q1 18.

It reduces the probability for accidents and reduces traffic congestion on local roads. Terminals can be strategically placed on the customer's acreage to reduce truck time on public roads. Miles driven can be reduced further by not shipping sand in box solutions. Most box solutions hold between 20 and 25 tons of sand while trucks can hold up to 35 tons. Therefore, the number of trucks on the road can be further reduced in some areas by as much as 50%. 26 smartsand® Mine to Wellsite Solutions®#27SmartSystem TM Wellsite Storage Solutions Features Transported using specialized trailer for unassisted setup in five minutes.
