## OUR 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™ wellsite proppant storage capabilities.

We currently market our products and services primarily to oil and natural gas exploration and production companies and oilfield service companies. We sell our sand and provide wellsite proppant storage solutions services and equipment under flexible contract terms tailored to meet our customers' needs. Our recent expansion through the addition of the Eagle Materials proppant business has allowed us to obtain new customers and offer broader opportunities to our existing 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 SmartPath™ transloader and SmartDepot™ portable wellsite proppant storage silos, and the industry experience of our senior management team make us a highly attractive provider of frac sand and proppant logistics services from the mine to the wellsite.



■Mobile wellsite proppant unloading system
■Smallest footprint in the industry
■Drive over conveyor OR pneumatic for rapid unloading
■Unmatched internal dust suppression system
■Integrated with our smart depot \( ^{™} \)  storage silo to create our smartsystem \( ^{™} \)  last mile solution

“In 2020, we generated $17 million in free cash flow, $38 million in net income and reduced our debt by approximately $8 million.”



## DEAR FELLOW STOCKHOLDERS,

In 2020, despite the COVID-19 pandemic, we continued to execute our profitable and sustainable long-term strategy of providing sand and logistics services from the mine to the wellsite. Our low leverage and financial discipline have allowed us to grow our capacity at a time when many of our peers were scaling back. As we move forward, we continue to center our business strategy around:

• Being the lowest-cost producer of high-quality Northern White Sand;

• Maintaining low debt levels, and being one of the lowest leveraged companies in the proppant supply and services industry;

• Participating in accretive acquisition opportunities that don’t risk our balance sheet;

• Delivering efficient and sustainable supply chain logistics from the mine all the way to the wellsite;

• Increasing utilization of our facilities and our last mile SmartSystems;

• Working with our existing and new customers to provide flexible solutions to meet their long-term proppant needs; and

• Maintaining our commitments to quality and safety, while also working to minimize the environmental impact of our operations.

We know that the quality of our sand and the quality of our services are the keys to our success; our ability to deliver both consistently is what keeps our customers coming back to us over-and-over again.




# ENVIRONMENTAL, SOCIAL & GOVERNANCE

We remain committed to maintaining high environmental, social and governance standards. Our existing policies and business operations are compatible with current United Nations (UN) principles. Building on this, we launched our formal Environmental, Social and Governance (ESG) program in the first quarter of 2020. We will continue to support our ESG efforts through an ethical, fair, independent and diverse governance structure. In accordance with the UN Paris Accord, we continue to assess our carbon footprint and have started our first reclamation project. The picture below represents our recently planted Northside Oakdale facility reclamation project.

# FINANCIAL STRENGTH

Smart Sand remains focused on generating positive free cash flow and maintaining low debt levels. In 2020, we generated $17 million in free cash flow, $38 million in net income, as well as reduced our debt by approximately $8 million.

In addition to generating positive free cash flow in 2020, in 2021 we expect to have sufficient liquidity to support the continued expansion of our SmartSystems fleet. Our ABL credit facility remains un-drawn and we continue to be one of the lowest levered companies in the proppant industry and the oilfield service sector.

The downturn in the oil markets in 2020 as a result of the COVID-19 pandemic provided a harsh reminder of the need to prudently manage our cash flows and debt level. As we've said time and time again, we believe maintaining a strong balance sheet and low debt levels are essential to remaining successful and competitive in this commodity business.



## RECENT ACQUISITION

In September 2020, we acquired the idled proppant business from Eagle Materials, which included two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity. We were able to complete this acquisition without taking on debt or significantly impacting our liquidity. In the fourth quarter, we reopened and began shipping out of the Utica mine, which has approximately 1.6 million tons of annual processing capacity. This facility has access to the BNSF Class I rail line, which has allowed us to offer broader and more efficient options to our customers. While we do not currently expect to reopen the New Auburn site for the foreseeable future, we remain ready to pivot to this site should market dynamics support this incremental capacity.

## FUTURE PLANS

As we have always done, we will continue to focus our efforts on delivering strong long-term returns for our stockholders. We will do this by continuing to emphasize fiscal discipline, while also taking advantage of opportunities to increase the utilization and efficiency of our asset base. We intend to continue to broaden our customer base through expanded offerings of sand, logistics and wellsite storage solutions. We also are looking for ways to bolster our already strong reputation regarding safety and ESG standards. We believe the market will ultimately reward providers that can provide sustainable efficient sourcing and delivery of sand from the mine all the way to the wellsite.

Business Efficiency Opportunities: The recent challenges with COVID-19 and reduced proppant demand has presented opportunities to increase the efficiency of the business in a smart and measured fashion. We are constantly assessing the marketplace to determine if there are areas that we can grow and/or increase our utilization of our existing assets and diversify our business, while continuing to responsibly manage our cash and limit our expenses. Our facilities now have access to three Class I railroads and can efficiently deliver sand to every operating basin in the United States. Our focus continues to be increasing the utilization of our existing asset base through increased sales volumes while continuing to assess new opportunities that complement our business strengths.

Growing our Wellsite Storage Solutions Business: We remain committed to the continued development of our SmartSystems wellsite proppant storage solution. We believe this system provides the most efficient and sustainable solution for sand management at the wellsite. Also, consistent with our emphasis on safety, our SmartSystems include both active and passive dust suppression and are engineered to operate safely with minimal respirable silica. Over the past year, we have completed the development of our proprietary SmartPath transloader, which provides fast and efficient unloading of proppant while also allowing us to maintain the small footprint enjoyed by our customers. We believe that increased adoption of the SmartPath could lead to a movement away from outdated and unsafe box technology in favor of the safer and more efficient operation offered by our SmartSystems solution.

Improving our strong safety and environmental performance: At Smart Sand, we are always looking to better ourselves and the community around us. For years we have operated to meet or exceed MSHA requirements for respirable silica, and our SmartSystems technology is tailor-made for the current OSHA silica standards. We consistently go the extra mile to reduce our impact on the land, air, water, atmosphere, and our local neighbors. We prioritize safety and continue to be a member of the Wisconsin Green Tier, which invites companies to reach for a higher level of environmental performance and to go beyond regulated requirements.



# MINE TO WELLSITE SOLUTIONS
Smart Sand's Business Offerings



We are proud of our performance this past year managing through the challenges presented to us, but as we start to emerge from the COVID-19 pandemic, we need to look to build our business for the future while also learning valuable lessons from our past.

We believe that the future is promising for Smart Sand. We are proud to produce high-quality Northern White sand, which we strongly believe leads to better long-term well results. As supported by the recent acquisition, we believe finer mesh Northern White sand outperforms regional sand in nearly every measurable way, most importantly in crush strength and turbidity. As lateral lengths continue to grow, so does the need for Northern White sand. Northern White sand continues to be the proppant of choice in the Bakken, Marcellus and Utica basins and we believe that there remains a value proposition in the other operating basins as well.

In addition, by working with our railroad partners to deliver competitive shipping costs and continuously improving our SmartSystems wellsite proppant storage solutions, we believe that our customers will look to us as the leader in providing sustainable, efficient and cost-effective logistics services to deliver our product to the wellsite. We will do this with the strong focus on safety and environmental awareness that we have built our reputation on over the years.

While we are always looking for ways to grow and improve our business, the last year has taught us valuable lessons in financial discipline and contingency planning. Our ability to manage our finances, reduce expenses, and increase efficiencies during the global pandemic allowed us to increase our footprint within the industry while many of our peers were pulling back. We will build on these lessons to continue making us stronger as we move forward.

We operate in uncertain times and a volatile industry as demonstrated over the past year with the impacts of the global COVID-19 pandemic, but we rose to the challenge. We believe we can continue to deliver positive long-term operating results staying true to our core principle strategies of safely and efficiently providing and delivering high-quality sand to the wellsite. Smart Sand will continue to be the model for long-term success in our industry.

Sincerely,



Chief Executive Officer

## 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 primarily to oil and natural gas exploration and production companies and oilfield service companies, sell our sand under a combination of long-term take-or-pay contracts and spot sales in the open market, and provide wellsite proppant storage solutions services and equipment under flexible contract terms custom tailored to meet customers' needs. 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 own and operate a frac sand mine and related processing facility near Oakdale, Wisconsin, at which we have approximately 315 million tons of proven recoverable sand reserves as of December 31, 2020. We incorporated in Delaware in July 2011 and began operations with 1.1 million tons of annual nameplate processing capacity in July 2012. After several expansions, our current annual processing capacity at our Oakdale facility is approximately 5.5 million tons of frac sand. Our integrated Oakdale facility, with on-site rail infrastructure and wet and dry sand processing facilities, has access to two Class I rail lines and enables us to process and cost-effectively deliver products to our customers.

In September 2020, we acquired from Eagle Materials Inc., a Delaware corporation (“Eagle”), 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”). The primary assets of Eagle Proppants Holdings and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the BNSF Class I rail line through the Peru, Illinois transload facility. We began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020. The New Auburn, Wisconsin mine is currently not producing sand.

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. The Van Hook terminal became operational in April 2018. Since operations commenced, we have been providing Northern White sand in-basin at this terminal to our contracted and spot sales customers. This terminal 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.

For the years ended December 31, 2020, 2019 and 2018, we generated net income of approximately $38.0 million, $31.6 million and $20.1 million, respectively, and Adjusted EBITDA of approximately $20.5 million, $87.1 million and $67.8 million, respectively. For the definition of Adjusted EBITDA and a reconciliation to its most directly comparable financial measure calculated and presented in accordance with U.S. GAAP, please read “Note Regarding Non-GAAP Financial Measures.” For more financial information about our business, please read “Selected Financial Data.”

## Business Combination

On September 18, 2020, we acquired from Eagle all of the issued and outstanding interests in Eagle Proppants Holdings for aggregate consideration of approximately $2.1 million. In satisfaction of the purchase price, we issued to Eagle 1,503,759 shares of our common stock. The number of 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 acquisition.

We determined our acquisition of Eagle Proppants Holdings is not a significant acquisition in accordance with the final rules adopted as part of the SEC’s disclosure effectiveness initiative. Management does not believe that pro forma financial



information would enhance a user’s understanding of the acquired business and has not included pro forma financial information in this discussion.

The primary assets of Eagle Proppants Holdings and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the BNSF Class I rail line through the Peru, Illinois transload facility.

The estimated aggregate fair value of the net assets acquired is $41.7 million, which exceeds the total consideration and results in a bargain purchase gain of $39.6 million on the acquisition date, which is included in net income for the year ended December 31, 2020.

In connection with our acquisition of Eagle Proppants Holdings, the Company, as borrower, also entered into a $5.0 million Acquisition Liquidity Support Facility. We may draw on the Acquisition Liquidity Support Facility to support the working capital needs of the acquired business during the twelve month period ending September 18, 2021. Beginning with the calendar quarter ending December 31, 2021, any outstanding amounts borrowed will amortize over the following three years. There were no borrowings outstanding on this facility as of or during the year ended December 31, 2020.

We believe this acquisition broadens our mine to wellsite capabilities by adding high quality sand mining and processing assets coupled with enhanced logistics options that provide direct access to an additional Class I rail line. We believe these additional mining and logistics resources help secure our ability to be the preferred provider of Northern White Sand in the proppants market. With this acquisition, we believe we will be able to expand our footprint into new basins, gain access to new and enhanced logistics options, broaden our customer base and complement our mine to wellsite supply and logistics capabilities.

## Market

During the second half of 2018, the demand for Northern White sand decreased from historical levels, which we believe was due primarily to insufficient takeaway capacity for the incremental increases in oil and natural gas production coming online, along with increased availability of regional sand as a source of proppant in the Permian basin. Additionally, oil and natural gas companies reduced their spending in the latter portion of the year due to strong spending in the first half of 2018, decreasing oil prices in the fourth quarter of 2018 and demands from their investors for more disciplined capital spending. Demand briefly recovered during the summer of 2019 before declining toward the end of 2019 as oil and gas companies exhausted their budgets and managed their capital spending to be in line with their expected operating cash flows. During the first quarter of 2020, demand again briefly increased before declining due to oil prices dropping to all-time lows as a result of decreased demand for oil from the COVID-19 coronavirus pandemic, as well as a temporary increase in global oil supply driven by disagreements with respect to oil pricing between Russia and members of the Organization of the Petroleum Exporting Countries (“OPEC”), particularly Saudi Arabia. The COVID-19 coronavirus pandemic has caused a global decrease in all means of travel, the closure of borders between countries and a general slowing of economic activity worldwide, which has decreased the demand for oil. In early March, discussions between Russia and Saudi Arabia deteriorated and the countries ended a three-year supply level agreement, which resulted in each country increasing its oil production. Subsequently, Russia and OPEC agreed to certain production cuts to mitigate the decline in the price of oil. While oil and natural gas prices have recently risen as a result of supply-led OPEC policy, the ongoing rollout of a COVID-19 vaccine and multinational economic stimulus actions, such prices are expected to continue to be volatile as a result of these events, and we cannot predict when prices will stabilize.

Increased supply of sand coupled with lower oil demand has resulted in lower demand for our products and has led to reduced interest in long term contracts as customers have instead trended toward purchasing their frac sand supply in the spot market at market prices.

Northern White frac sand, which is found predominantly in Wisconsin and limited portions of Minnesota and Illinois, 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. We expect demand for our frac sand to continue to be supported from 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 the development of North America’s unconventional oil and natural gas reservoirs will continue to grow and increased proppant usage per well trends will continue, particularly with respect



to finer 100 mesh and 40/70 mesh sizes. Finally, we believe that the adoption of our SmartSystems in the marketplace will allow us to sell more sand through packaging it with our last mile solutions.

## Business Strategies

Our principal business objective is to be the premier provider of sustainable frac sand supply and logistics solutions to our customers. We do this through supporting our existing customers, expanding our market share, being a low-cost producer of high-quality Northern White Sand, maintaining low debt leverage and managing efficient and sustainable supply chain logistics from the mine to the wellsite. We believe that by executing these business strategies, we will be able to increase long-term stockholder value. We expect to achieve this objective through the following business strategies:

Expanding and optimizing our existing logistics infrastructure and developing additional origination and destination points. We expect to continue to capitalize on our Oakdale facility’s ability to ship on two Class I rail carriers to maximize our product shipment rates, increase our railcar utilization and lower our transportation costs. We have the ability to simultaneously accommodate multiple unit trains on-site with the Canadian Pacific rail network while also having the ability to ship our frac sand directly to our customers on a second Class I rail carrier through our transloading facility located on the Union Pacific rail network approximately three miles from our Oakdale facility. This access to two Class I rail carriers from Oakdale provides increased delivery options for our customers, greater competition between our rail carriers and potentially lower freight costs.

In September 2020, we significantly expanded our existing logistics infrastructure through the acquisition of Eagle Proppants Holdings, which added new origination and destination points to our existing capabilities. Our newly acquired Peru transload terminal located in close proximity to our newly acquired Utica mine and frac sand processing facility offers additional capability to ship products on a third Class I rail carrier, the BNSF.

In 2018, we added a multi-unit train capable terminal in Van Hook, North Dakota, which we further expanded in 2019. We believe this allows us to be one of the most efficient and low-cost sources of frac sand in the Bakken Formation in the Williston Basin.

Additionally, our SmartSystem wellsite storage and proppant management systems allows us to offer expanded logistics services to our customers.

The benefits of our long-term growth strategy for in-basin delivery of sand include expanding our customer base by marketing through our own terminals, more opportunity for spot sales by forward deploying sand and the opportunity to capture incremental margin on the sale of sand farther down the supply chain by managing the cost of rail, terminal and wellsite storage operations. Additionally, having a presence in-basin gives us an opportunity to have a base of operations from which to market our SmartSystems wellsite proppant storage solutions. Through the expansion of our SmartSystems fleet and addition of new origination and destination options, we continue evaluating ways to reduce the landed cost of our products in-basin and to the wellsite for our customers while increasing our customized service offerings to provide our customers with additional delivery and pricing alternatives, including selling product on an “as-delivered” basis to the wellsite.

• Focusing on organic growth by increasing the utilization of our mine and frac sand processing facilities. We intend to continue pursuing opportunities to maximize the value and the utilization of our Oakdale and Utica facilities through the addition of new customers and increased sales volumes. Despite the emergence of regional sand in oil and natural gas producing basins, we believe the proppant market continues to offer attractive long-term growth fundamentals for Northern White frac sand due to its superior well results outweighing the incremental cost savings of regional sand. We believe that coupling our premium proppant with long-term sustainable logistics supply services may mitigate the potential cost savings of using regional sand.

Demand for frac sand dropped to all-time lows in the first half of 2020, following the decline in demand for oil driven by both oversupply from OPEC and reduced demand from the COVID-19 pandemic. During the second half of 2020, demand began to increase as OPEC tensions and government travel restrictions eased. According to Spears and Associates, Inc. (“Spears”), demand in 2021 is expected to continue improving from first half 2020 lows as oil and gas markets continue to stabilize. According to Spears and Associates, Inc. (“Spears”), demand in 2021 is expected to remain steady as oil and gas markets stabilize.

• Focusing on being a low-cost provider and continuing to make process improvements. We continue to focus on being a low-cost provider, which we believe will allow us to compete effectively for sales of frac sand and to achieve attractive operating margins. Our low-cost structure results from a number of key attributes, including,



among others, our (i) relatively low royalty rates, (ii) majority of fine mineral reserve deposits, (iii) our facilities proximity to three Class I rail lines creates competition between railroads and other sand logistics infrastructure advantages, and (iv) our low levels of debt. We have strategically designed our operations to provide for low-cost production, including having dryers and wet plants enclosed in our Oakdale and Utica processing facilities that allow for year-round operation at both facilities. This allows us to more efficiently match our wet sand production with our drying capacity and to better utilize our workforce with a goal to reduce the overall cost of production. We continue to invest in capital projects and consider strategic acquisitions that increase efficiencies and offer the opportunity for a high return on investment. In addition, we seek to maximize our mining yields on an ongoing basis by targeting sales volumes that more closely match our reserve gradation in order to minimize waste in our processing. We also continue to evaluate other mining techniques to reduce the overall cost of our mining operations.

• Creating flexible sales activities. We believe that demand for our products will remain strong in basins where regional sand is not widely available, such as the Bakken in North Dakota, the Marcellus and Utica formations in the Northeast region of the United States and the Colorado and Wyoming basins. We continue to have discussions with operators in these regions regarding new relationship and growth opportunities. We also believe that the long-term benefits of high quality Northern White sand outweighs the short-term cost savings provided by regional sand in the Permian, Eagle Ford and SCOOP/STACK basins. We believe there are additional opportunities for customers in the Permian and other basins, which have regional supply, who are focused on the long-term performance of their production and on the long-term efficiency of their logistics.

While we continue to look for long-term contract opportunities, we intend to increase focus on shorter term contracts and increase sales in the spot market given the reluctance of our customers to enter into long-term take-or-pay contracts in the current market environment.

## Competitive Strengths

We believe that we will be able to successfully execute our business strategies because of the following competitive strengths:

- Long-lived, strategically located, high-quality reserve base. We believe our Oakdale facility is one of the few frac sand mine and production facilities that has the unique combination of a large high-quality reserve base of primarily fine mesh sand that is contiguous to its production and primary rail loading facilities. We have a minimum implied proven reserve life of approximately 57 years based on our current annual processing capacity of 5.5 million tons at our Oakdale facility.

Our Utica facility also has a large high-quality reserve base of primarily fine-mesh sand that is contiguous to the production facility and in close proximity to our Peru transload facility located on the BNSF railway. We have a minimum proven and probable reserve life of approximately 81 years based on our current annual processing capacity of 1.6 million tons at our Utica facility.

We believe our reserve base positions us well to take advantage of current market trends of increasing demand for finer mesh frac sand. We also believe that having our mine, processing facilities and primary rail loading facilities in close proximity provides us with an overall low-cost structure, which enables us to compete effectively for sales of Northern White frac sand and to achieve attractive operating margins.

- Intrinsic logistics advantage. We believe that we are one of the few frac sand producers with a facility custom-designed for the specific purpose of delivering frac sand to all of the major U.S. oil and natural gas producing basins by an on-site rail facility that can simultaneously accommodate multiple unit trains. Our on-site transportation assets at Oakdale include approximately nine miles of rail track in a triple-loop configuration and four railcar loading facilities that are connected to a Class I rail line owned by Canadian Pacific. We believe our customized on-site logistical configuration yields lower operating and transportation costs compared to manifest train or single-unit train facilities as a result of our higher railcar utilization, more efficient use of locomotive power and more predictable movement of product between mine and destination. In addition, we have a transload facility on a Class I rail line owned by Union Pacific in Byron Township, Wisconsin, approximately three miles from the Oakdale facility. This transload facility, which is also capable of handling multiple unit trains simultaneously, allows us to ship sand directly from Oakdale to our customers on more than one Class I rail carrier. We believe that we are the only sand facility in Oakdale, Wisconsin that has dual-served rail capabilities, which should create competition between our rail carriers and allow us to provide more competitive logistics options for our customers.



Our recently acquired frac sand mine and processing facility and transloading terminal in Illinois adds significant quality reserves and logistics assets that further increase our logistics advantage by providing access to another Class I rail line through our owned, multiple unit train capable Peru transload facility with direct access to the BNSF rail line. Additionally, the CSX, NS rail and barge access on the Illinois River to access the Mississippi River are available within short trucking distances. These additional logistics options give us greater access to operating basins in the Western United States allowing us to offer more competitive pricing to existing and new customers in these markets.

- Expanded logistics solutions. Our transloading terminal in Van Hook, North Dakota, became operational in April 2018 and was expanded in 2019. This terminal is capable of handling multiple unit trains simultaneously, and we have been providing in-basin sand at this terminal to our customers since operations began. This terminal has allowed us to expand our customer base and offer more efficient delivery options to customers operating in the Bakken Formation in the Williston Basin.

Our SmartSystems wellsite proppant storage and management products 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. 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 are capable of delivering sand to any onshore operating basin in the United States and Canada. We have direct access to 3 class I rail lines and additional access to 2 other class I rail lines and barge access to the Mississippi River, all of which give us superior advantage over many of our competitors by allowing us to offer more competitive pricing and delivery options to our customers.

- Sufficient liquidity and financial flexibility. We believe we have sufficient liquidity to support our operations and pursue our growth initiatives. As of December 31, 2020, we have cash on hand of $11.7 million. Further, we have a $20 million five-year senior secured asset-based lending credit facility with Jefferies Finance LLC, under which we had undrawn availability of $9.5 million as of December 31, 2020 and no outstanding borrowings. The available borrowing amount under the ABL Credit Facility is based on the Company’s eligible accounts receivable and inventory. The ABL Credit Facility matures on December 13, 2024. Additionally, in connection with our acquisition of Eagle Proppants Holdings, the Company, as borrower, also entered into a $5.0 million Acquisition Liquidity Support Facility. We may draw on the Acquisition Liquidity Support Facility to support our working capital needs of the acquired business during the twelve month period ending September 18, 2021. There were no borrowings outstanding on these facilities as of December 31, 2020 and our total available liquidity among cash and available borrowings was $26.2 million as of December 31, 2020.

• Experienced management team. The members of our senior management team bring significant experience to the market environment in which we operate. Their expertise covers a range of disciplines, including industry-specific operating and technical knowledge and experience managing businesses in a variety of operating conditions.

- Focus on safety and environmental stewardship. We are committed to maintaining a culture that prioritizes safety, the environment and our relationship with the communities in which we operate, actions we believe are critical to the success of our business. We are a Tier 1 participant in The Wisconsin Department of Natural Resources' Green Tier program, which encourages, recognizes and rewards companies for voluntarily exceeding environmental, health and safety legal requirements. Since 2016, Smart Sand has maintained International Organization for Standardization ("ISO") ISO 9001 and ISO 14001 registrations for our quality management system and environmental management system programs, respectively, for our Oakdale facility. We also have attained Green Professional status in Wisconsin's Green Master sustainability recognition program. We are one of a select group of companies who are members of the Wisconsin Industrial Sand Association, which promotes safe and environmentally responsible sand mining standards. In 2021, we expect to report energy consumption information regarding our carbon footprint.

## Our Customers

Our core customers are oil and natural gas exploration and production and oilfield service companies. We sell frac sand under long-term take-or-pay contracts as well as in the spot market, and provide proppant logistics solutions through our in-basin transloading terminal and SmartSystems wellsite proppant storage solutions and other logistics services.



Generally, customers under long-term take-or-pay contracts are required to take minimum volumes of sand or make shortfall payments for a specified period of time. We recognize revenue in our results of operations in the period in which the obligation becomes due.

We have found that, increasingly, customers are disinclined to enter into long-term contracts for their frac sand supply and have instead trended toward purchasing their frac sand supply in the spot market at market prices. Should our customer base continue to limit their exposure to longer term contracts, we will continue to focus on shorter term contracts and increasing sales in the spot market.

Customers renting SmartSystems are able to tailor the contract, including adjusting the number of SmartDepot silos and SmartPath transloaders to be supplied, to meet their short-term and long-term needs. We recognize rental revenue when the equipment is made available for the customer to use or other obligations in the contract are met. Our first SmartDepot silos became available in the third quarter of 2018 and the first set was contracted in January 2019.

For the year ended December 31, 2020, Rice Energy (a subsidiary of EQT Corporation), Liberty and U.S. Well Services accounted for 28.1%, 21.7%, and 14.0%, respectively, of total revenue, and the remainder of our revenues were from 20 customers. For the year ended December 31, 2019, Liberty, Rice Energy (a subsidiary of EQT Corporation), Hess Corporation, and U.S. Well Services accounted for 23.8%, 19.0%, 15.5%, and 14.7%, respectively, of our total revenues, and the remainder of our revenues were from 20 customers. For the year ended December 31, 2018, Liberty, EQT, WPX Energy, and Hess accounted for 22.8%, 21.4%, 11.6%, and 10.6%, respectively, of our total revenues, and the remainder of our revenues were from 18 customers. Please read “Risk Factors—Risks Inherent in Our Business—A substantial majority of our revenues have been generated under contracts with a limited number of customers, and the loss of, material nonpayment or nonperformance by or significant reduction in purchases by any of them could adversely affect our business, results of operations and financial condition.” For the years ended December 31, 2020, 2019, and 2018, we generated approximately 83.4%, 92.5%, and 80.1%, respectively, of our revenues from frac sand delivered under long-term take-or-pay contracts.

## Capital Plans

We expect to continue expanding our SmartSystems wellsite proppant storage solutions and evaluate other proposed projects and related expenditures, such as improvements at our mines and processing facilities and investments in transload facilities located in various operating basins, in light of customer demand and energy market trends. There can be no assurance, however, that all or any of these initiatives will be executed or that the results therefrom will be materially beneficial to our financial performance.

## Industry Trends Impacting Our Business

Unless otherwise indicated, the information set forth under this section, including all statistical data and related forecasts, is derived from Spears’ “Proppant Market Report with Frac Market Overview - Q4 2020” published in the first quarter of 2021. While we are not aware of any misstatements regarding the proppant industry data presented herein, estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors.”

## Demand Trends

According to Spears, the North American proppant market, including frac sand, ceramic and resin-coated proppant, was approximately 46 million tons in 2020, which is approximately 50% decrease from the 94 million tons Spears reported for 2019. Spears estimates that 2021 demand will be flat with 2020 demand.

## Supply Trends

There has been consolidation activity including mergers, acquisitions, closures of mines and bankruptcy filings among our peers. Additional consolidation activity is expected in 2021 in the mining, transloading and logistics businesses.

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 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. 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, we’ve seen competitors in the Northern White frac sand market reduce their capacity by shuttering or idling operations as the shift to finer sands in hydraulic fracturing of oil and natural gas wells erodes the ongoing economic viability of producing coarser grades of sand.

## Environmental, Social & Governance

In 2020, we refined our scope of setting a Company objective of adopting a formal Environmental, Social & Governance (“ESG”) program. Smart Sand already has a strong record of environmental performance. In 2014, we joined the Wisconsin Green Tier program, a marquee public/private partnership, under which the Wisconsin Department of Natural Resources worked with us on a plan to meet applicable legal requirements and to improve our facility from an environmental perspective. In addition to documenting seven years of compliant operations, we have worked on, among other things, protecting wetlands, reducing usage and impact of heavy equipment, reducing fuel usage of equipment and vehicles and defining best practices for onsite water management. We are also a member of Wisconsin’s sustainability initiative, Green Masters. As part of this program, we have completed a detailed survey of our sustainability and social responsibility activities and started the process of a complete carbon inventory. As a mining company, we invest and plan for reclamation, ensuring that the land is returned to beneficial use. Smart Sand has held ISO 9001/14001-2015 environmental and quality management systems for the past five years. Smart Sand is also a member of the Wisconsin Industrial Sand Association, a select group of mining companies focused on safety, environmental and public policy.

One of the goals of the United Nations’ Paris Agreement is a carbon neutral world by the year 2050 and we are aligned with this goal. We believe that reducing our carbon footprint will lead to a better world. As a mining company, we are an energy consumer, and we have already seen that we can reduce greenhouse gas emissions by using the best technologies and taking a thoughtful approach to our energy choices. We know that energy consumption is only one part of ethical operations. For additional information regarding the United Nations’ Paris Agreement, see “Item 1A Risk Factors-Risks Related to Environmental, Mining and Other Regulation-Climate change legislation and regulatory initiatives could result in increased compliance costs for us and our customers.”

We provide social value through our excellent employment opportunities. Our first priority is keeping our employees safe, which we accomplish through daily training and inspections. Our business supports hundreds of families and we are proud to offer rewarding and interesting work with competitive compensation and benefits. We promote from within, provide continuous training, hire with a passion for diversity and provide every employee with the opportunity to participate in retirement plans and ownership of the Company. Smart Sand is an active charitable partner in the communities in which it operates, making both financial and time investments in those communities.

Sustainability has always been part of the Smart Sand story, but we are looking forward to evaluating what we have done and identifying improvement opportunities. We are embracing this growing movement and designing an area in our website to articulate our ESG goals and report on our performance.

## Permits

We operate in a highly regulated environment overseen by many governmental regulatory and enforcement bodies at the local, state and federal levels. To conduct our operations, we are required to have obtained permits and approvals that address environmental, land use and safety issues at our operating facilities. Our current and planned areas for excavation at our mining facilities are permitted for extraction of our proven reserves. Portions of our facilities lie in areas designated as wetlands, which will require additional local, state and federal permits prior to mining and reclaiming those areas.

We also must meet requirements for certain international standards concerning safety, greenhouse gases and rail operations. We have voluntarily agreed to meet the standards of the Wisconsin Department of Natural Resources’ Green Tier program, the National Industrial Sand Association (“NISA”) and the Wisconsin Industrial Sand Association. Further, for Oakdale, we have agreed to meet the standards required to maintain our ISO 9001-2015 and ISO 14001-2015 quality/environmental management system registrations. These voluntary requirements are tracked and managed along with our permits.



While resources invested in securing permits are significant, this cost has not had a material adverse effect on our results of operations or financial condition. We cannot ensure that existing environmental laws and regulations will not be reinterpreted or revised or that new environmental laws and regulations will not be adopted or become applicable to us. Revised or additional environmental requirements that result in increased compliance costs or additional operating restrictions could have a material adverse effect on our business.

## Major Stockholder

Our largest stockholder is Clearlake Capital Group, L.P., together with its affiliates and related persons (“Clearlake”). Clearlake is a leading private investment firm founded in 2006. With a sector-focused approach, the firm seeks to partner with world-class management teams by providing patient, long-term capital to dynamic businesses that can benefit from Clearlake’s operational improvement approach, O.P.S. \( ^{®} \) . The firm’s core target sectors are industrials, technology, and consumer. Clearlake currently has over 25 billion of assets under management and its senior investment principals have led or co-led over 200 investments. We believe our relationship with Clearlake provides us with a unique resource to effectively compete for acquisitions within the industry by being able to take advantage of their experience in acquiring businesses to assist us in seeking out, evaluating and closing attractive acquisition opportunities over time.

## Competition

The proppant industry is highly competitive. Please read “Risk Factors—Risks Inherent in Our Business—We face significant competition that may cause us to lose market share.” There are numerous large and small producers in all sand producing regions of North America with whom we compete, many of which also offer solutions for unloading, storing and delivering proppant to the wellsite. Our main competitors include Badger Mining Corporation, Hi-Crush, Inc., Covia Holdings Corporation, U.S. Silica Holdings, Inc., Black Mountain Sand, Vista Proppants and Logistics, Atlas Sand, Capital Sand Company and Solaris Oilfield Infrastructure, Inc.

Although some of our competitors may have greater financial or natural resources than we do, we believe that we are well-positioned competitively due to our low cost of sand production, low debt levels, logistics infrastructure and high-quality, balanced reserve profile and patented SmartSystems wellsite proppant storage solutions, which offer numerous benefits over our competition. The most important factors on which we compete are our service capabilities, product quality, proven performance, sand characteristics, transportation capabilities, reliability of supply, price, logistics services and the performance of patented SmartSystems wellsite proppant storage solutions technology. Demand for frac sand and logistics solutions and the prices that we will be able to obtain for our products, to the extent not subject to a fixed price or take-or-pay contract, are closely linked to proppant consumption patterns for the completion of oil and natural gas wells in North America. These consumption patterns are influenced by numerous factors, including, among other things, the price for oil and natural gas and hydraulic fracturing activity, including the number of stages completed and the amount of proppant used per stage. Further, these consumption patterns are also influenced by the location, quality, price and availability of frac sand and other types of proppants such as resin-coated sand and ceramic proppant.

## 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 wet sand to meet demand in the winter months. These higher cash operating costs are capitalized into inventory and expensed when these tons are sold, which can lead to us having higher overall costs in the first and fourth quarters of each calendar year as we expense inventory costs that were previously capitalized. However, we have enclosed, indoor wet plants at both of our processing facilities, which allow us to produce wet sand inventory year-round to support a large 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. For a discussion of the impact of weather on our operations, please read “Risk Factors—Seasonal and severe weather conditions could have a material adverse impact on our business, results of operations and financial condition” and “Risk Factors—Our cash flow fluctuates on a seasonal basis.”



## Intellectual Property

Our intellectual property primarily consists of trade secrets, know-how and trademarks. We own patents and have patent applications pending related to our SmartSystems wellsite proppant storage solutions. All of the issued patents have an expiration date after July 2030. With respect to our other products, we principally rely on trade secrets, rather than patents, to protect our proprietary processes, methods, documentation and other technologies, as well as certain other business information. For a discussion of the impact of our intellectual property, please read “Risk Factors—If we are unable to fully protect our intellectual property rights, we may suffer a loss in our competitive advantage” and “Risk Factors—We may be adversely affected by disputes regarding intellectual property rights of third parties.”

## Insurance

We believe that our insurance coverage is customary for the industry in which we operate and adequate for our business. As is customary in the proppant industry, we review our safety equipment and procedures and carry insurance against most, but not all, risks of our business. Losses and liabilities not covered by insurance would increase our costs. To address the hazards inherent in our business, we maintain insurance coverage that includes physical damage coverage, third-party general liability insurance, employer’s liability, business interruption, environmental and pollution and other coverage, although coverage for environmental and pollution-related losses is subject to significant limitations. For additional discussion regarding our insurance, please read “Risk Factors—Our operations are subject to operational hazards and unforeseen interruptions for which we may not be adequately insured.”

## Environmental and Occupational Health and Safety Regulations

We are subject to stringent and complex federal, state, local and international laws and regulations governing the discharge of materials into the environment or otherwise relating to protection of worker health, safety and the environment. Compliance with these laws and regulations may expose us to significant costs and liabilities and cause us to incur significant capital expenditures in our operations. Any failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, imposition of remedial obligations, and the issuance of injunctions delaying or prohibiting operations. Private parties may also have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property damage. In addition, the trend in environmental regulation is to place more restrictions on activities that may affect the environment, and thus, any changes in, or more stringent enforcement of, these laws and regulations that result in more stringent and costly pollution control equipment, the occurrence of delays in the permitting or performance of projects, or waste handling, storage, transport, disposal or remediation requirements could have a material adverse effect on our operations and financial position.

We do not believe that compliance by us with federal, state, local or international environmental laws and regulations will have a material adverse effect on our business, financial position or results of operations or cash flows. We cannot be assured, however, that future events, such as changes in existing laws or enforcement policies, the promulgation of new laws or regulations or the development or discovery of new facts or conditions adverse to our operations will not cause us to incur significant costs. The following is a discussion of material environmental and worker health and safety laws, as amended from time to time that relate to our operations or those of our customers that could have a material adverse effect on our business.

## Air Emissions

Our operations are subject to the federal Clean Air Act (“CAA”) and related state and local laws, which restrict the emission of air pollutants and impose permitting, monitoring and reporting requirements on various sources. Over the next several years, we may be required to incur certain capital expenditures for air pollution control equipment or to address other air emissions-related issues. Changing and increasingly stringent requirements, future non-compliance, or failure to maintain necessary permits or other authorizations could require us to incur substantial costs or suspend or terminate our operations.

## Climate Change

In recent years, the U.S. Congress has considered legislation to reduce emissions of greenhouse gases (“GHG”). We are unable to predict actions that may be taken by the Federal government however, a number of states are addressing GHG emissions, primarily through the development of emission inventories or regional GHG cap and trade programs. Depending on the particular program, we could be required to control GHG emissions or to purchase and surrender allowances for GHG



emissions resulting from our operations. Independent of Congress, the U.S. Environmental Protection Agency (“EPA”) has adopted regulations controlling GHG emissions under its existing authority. Compliance with new legislation may require us to incur substantial costs or suspend or terminate our operations.

President Biden and the Democratic Party, which now controls Congress, have identified climate change as a priority, and it is likely that new executive orders, regulatory action, and/or legislation targeting GHG emissions, or prohibiting, delaying or restricting oil and gas development activities in certain areas, will be proposed and/or promulgated during the Biden Administration. For example, the acting Secretary of the Department of the Interior recently issued an order preventing staff from producing any new federal fossil fuel leases or permits without sign-off from a top political appointee, and President Biden recently announced a moratorium on new oil and gas leasing on federal lands and offshore waters pending completion of a comprehensive review and reconsideration of Federal oil and gas permitting and leasing practices. President Biden’s order also established climate change as a primary foreign policy and national security consideration, affirms that achieving net-zero GHG emissions by or before midcentury is a critical priority, affirms the Biden Administration’s desire to establish the United States as a leader in addressing climate change, generally further integrates climate change and environmental justice considerations into government agencies’ decision-making, and eliminates fossil fuel subsidies, among other measures. President Biden also announced that the United States is taking steps to reenter the Paris Agreement.

## Water Discharges

The Clean Water Act (“CWA”) and analogous state laws impose restrictions and strict controls with respect to the discharge of pollutants, including spills and leaks of oil and other substances, into state waters or waters of the United States. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. The CWA and regulations implemented thereunder also prohibit the discharge of dredge and fill material into regulated waters, including jurisdictional wetlands, unless authorized by the Army Corps of Engineers (“Corps”) pursuant to an appropriately issued permit. In addition, the CWA and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. Compliance with new rules and legislation could require us to face increased costs and delays with respect to obtaining permits for expansion activities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties as well as other enforcement mechanisms for non-compliance with discharge permits or other requirements of the CWA and analogous state laws and regulations.

## Hydraulic Fracturing

We supply frac sand to hydraulic fracturing operators in the oil and natural gas industry. Hydraulic fracturing is an industry practice that is used to stimulate production of oil and natural gas from low permeability hydrocarbon bearing subsurface rock formations. The hydraulic fracturing process involves the injection of water, proppants, and chemicals under pressure into the formation to fracture the surrounding rock, increase permeability and stimulate production. Although we do not directly engage in hydraulic fracturing activities, our customers purchase our frac sand for use in their hydraulic fracturing activities.

The adoption of new laws or regulations at the federal or state levels imposing reporting obligations on, or otherwise limiting or delaying, the hydraulic fracturing process could make it more difficult to complete natural gas wells, increase our customers’ costs of compliance and doing business, and otherwise adversely affect the hydraulic fracturing services they perform, which could negatively impact demand for our frac sand.

## Non-Hazardous and Hazardous Wastes

The Resource Conservation and Recovery Act (“RCRA”) and comparable state laws control the management and disposal of hazardous and non-hazardous waste. These laws and regulations govern the generation, storage, treatment, transfer and disposal of wastes that we generate. In the course of our operations, we generate waste that are regulated as non-hazardous wastes and hazardous wastes, obligating us to comply with applicable standards relating to the management and disposal of such wastes. In addition, drilling fluids, produced waters, and most of the other wastes associated with the exploration, development, and production of oil or natural gas, if properly handled, are currently exempt from regulation as hazardous waste under RCRA and, instead, are regulated under RCRA’s less stringent non-hazardous waste provisions, state laws or other federal laws. However, it is possible that certain oil and natural gas drilling and production wastes now classified as non-hazardous could be classified as hazardous wastes in the future. A loss of the RCRA exclusion for drilling fluids, produced waters and related wastes could result in an increase in our customers’ costs to manage and dispose of generated wastes and a corresponding decrease in their drilling operations, which developments could have a material adverse effect on our business.



## Site Remediation

The Comprehensive Environmental Response, Compensation, and Liability Act, as amended (“CERCLA”) and comparable state laws impose strict, joint and several liability without regard to fault or the legality of the original conduct on certain classes of persons that contributed to the release of a hazardous substance into the environment. These persons include the owner and operator of a disposal site where a hazardous substance release occurred and any company that transported, disposed of, or arranged for the transport or disposal of hazardous substances released at the site. Under CERCLA, such persons may be liable for the costs of remediating the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain health studies. In addition, where contamination may be present, it is not uncommon for the neighboring landowners and other third parties to file claims for personal injury, property damage and recovery of response costs. We have not received notification that we may be potentially responsible for cleanup costs under CERCLA at any site.

## Endangered Species

The Endangered Species Act (“ESA”) restricts activities that may result in a “take” of endangered or threatened species and provides for substantial penalties in cases where listed species are taken by being harmed. Harm under the ESA includes acts that actually kill or injure wildlife as well as significant habitat modification or degradation that significantly impairs essential behavioral patterns, including breeding, feeding or sheltering. Take prohibitions also protect migratory birds under the MBTA.

The dunes sagebrush lizard is one example of a species that, if listed as endangered or threatened under the ESA, could impact our operations and the operations of our customers. The dunes sagebrush lizard is found in the active and semi-stable shinney oak dunes of southeastern New Mexico and adjacent portions of Texas, including areas where our customers operate and our frac sand facilities may be located. The United States Fish and Wildlife Service (“USFWS”) is currently reviewing a petition from the Center for Biological Diversity and the Defenders of Wildlife to list the dunes sagebrush lizard as endangered or threatened under the ESA, and on July 16, 2020, issued a 90-day finding that the petition presents substantial information that listing may be warranted and the agency will conduct a more thorough review to determine whether listing may be warranted. If the dunes sagebrush lizard is listed as an endangered or threatened species, our operations and the operations of our customers in any area that is designated as the dunes sagebrush lizard’s habitat may be limited, delayed or, in some circumstances, prohibited, and our and our customers could be required to comply with expensive conservation measures intended to protect the dunes sagebrush lizard and its habitat.

The USFWS has approved several Enhancement of Survival Permits that allow operations in designated habitats to continue if the dunes sagebrush lizard is listed provided that qualification criteria and conservation measures required by such permits are met. One such permit is referred to as the Texas Conservation Plan (“TCP”). The TCP was developed as a voluntary conservation plan for the dunes sagebrush lizard by the Texas Comptroller, which served as the permit holder until the transfer of the TCP to a new permit holder in October 2020. Smart Sand is a participant in the TCP and has enrolled 2,713-acres of its land in Winkler, County, Texas. The USFWS issued a second permit for operations in Texas that may affect the dunes sagebrush lizard in January 2021. The permits cover incidental “take” of the dunes sagebrush lizard associated with oil and gas exploration and development, sand mining, renewable energy development and operations, pipeline construction and operations, local government activities, agricultural activities, and general construction activities within the CCAA permit area that could affect suitable habitat. Smart Sand’s enrollment in the TCP minimizes the potential that new or more stringent conservation measures or land, water, or resource use restrictions beyond the measures and restrictions in the TCP may be required for that property.

To the extent species are listed under the ESA or similar state laws, or are protected under the MBTA, or previously unprotected species are designated as threatened or endangered in areas where we or our customers operate, we could experience increased costs arising from species protection measures and delays or limitations in our or our customers' performance of operations, which could adversely affect or reduce demand for our frac sand.

## Mining and Workplace Safety

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.

OSHA has promulgated new 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, and in August 2019 published a formal request for information and data on feasible, best practices to protect miners' health from exposure to silica in respirable dust. 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. Smart Sand also adheres to the NISA’s respiratory protection program, and ensures that workers are provided with fitted respirators and ongoing radiological monitoring.

## Environmental Reviews

Our operations may be subject to broad environmental review under the National Environmental Policy Act, as amended, (“NEPA”). NEPA requires federal agencies to evaluate the environmental impact of all “major federal actions” significantly affecting the quality of the human environment. The granting of a federal permit for a major development project, such as a mining operation, may be considered a “major federal action” that requires review under NEPA. As part of this evaluation, the federal agency considers a broad array of environmental impacts, including, among other things, impacts on air quality, water quality, wildlife (including threatened and endangered species), historic and archeological resources, geology, socioeconomics, and aesthetics. NEPA also requires the consideration of alternatives to the project. The NEPA review process, especially the preparation of a full environmental impact statement, can be time consuming and expensive. The purpose of the NEPA review process is to inform federal agencies’ decision-making on whether federal approval should be granted for a project and to provide the public with an opportunity to comment on the environmental impacts of a proposed project. Though NEPA requires only that an environmental evaluation be conducted and does not mandate a particular result, a federal agency could decide to deny a permit or impose certain conditions on its approval, based on its environmental review under NEPA, or a third party could challenge the adequacy of a NEPA review and thereby delay the issuance of a federal permit or approval. In January 2020, the White House Council on Environmental Quality (“CEQ”) published a Notice of Proposed Rulemaking that would revise NEPA’s implementing regulations, with the stated purpose of facilitating more efficient and timely NEPA reviews. CEQ is currently soliciting public comments on its proposal through March 10, 2020. At this time we cannot predict what revisions, if any, will be made to NEPA’s implementing regulations, and what impacts, if any, they will have on our operations.

## State and Local Regulation

We are subject to a variety of state and local environmental review and permitting requirements. Some states, including Wisconsin where our current projects are located, have state laws similar to NEPA; thus, our development of a new site or the expansion of an existing site may be subject to comprehensive state environmental reviews even if it is not subject to NEPA. In some cases, the state environmental review may be more stringent than the federal review. Our operations may require state-law based permits in addition to federal permits, requiring state agencies to consider a range of issues, many the same as federal agencies, including, among other things, a project’s impact on wildlife and their habitats, historic and archaeological sites, aesthetics, agricultural operations, and scenic areas. Wisconsin has specific permitting and review processes for commercial silica mining operations, and state agencies may impose different or additional monitoring or mitigation requirements than federal agencies. The development of new sites and our existing operations also are subject to a variety of local environmental and regulatory requirements, including land use, zoning, building, and transportation requirements.

Demand for frac sand in the oil and natural gas industry drove a significant increase in the production of frac sand. As a result, some local communities expressed concern regarding silica sand mining operations. These concerns have generally included exposure to ambient silica sand dust, truck traffic, water usage and blasting. In response, certain state and local communities have developed or are in the process of developing regulations or zoning restrictions intended to minimize dust from becoming airborne, control the flow of truck traffic, significantly curtail the amount of practicable area for mining activities, provide compensation to local residents for potential impacts of mining activities and, in some cases, ban issuance of new permits for mining activities. To date, we have not experienced any material impact to our existing mining operations or planned capacity expansions as a result of these types of concerns. We would expect this trend to continue as oil and natural gas production increases.

In August 2014, we were accepted as a Tier 1 participant in Wisconsin’s voluntary Green Tier program, which encourages, recognizes and rewards companies for voluntarily exceeding environmental, health and safety legal requirements. Successful Tier 1 participants are required to demonstrate a strong record of environmental compliance, develop and implement an environmental management system meeting certain criteria, conduct and submit annual performance reviews to the Wisconsin Department of Natural Resources, promptly correct any findings of non-compliance discovered during these annual performance reviews, and make certain commitments regarding future environmental program improvements. Our most recent annual report required under the Tier 1 protocol was submitted to the Green Tier Program contact on August 1, 2019.



## Employees

As of December 31, 2020, we employed 228 people, of which 28 were employed under collective bargaining agreements. We offer competitive salaries and a comprehensive package of employee benefits, including bonuses, retirement savings plans, medical, dental, life and disability coverage. We consider our employee relations to be good.

## ITEM 1A. — RISK FACTORS

## Risks Inherent in Our Business

## Our business and financial performance depend on the level of activity in the oil and natural gas industry.

Substantially all of our revenues are derived from sales to companies in the oil and natural gas industry. As a result, our operations are dependent on the levels of activity in oil and natural gas exploration, development and production and prevailing oil and natural gas prices. More specifically, the demand for the proppants we produce and our wellsite storage solutions is closely related to the number of oil and natural gas wells completed in geological formations where sand-based proppants are used in fracturing activities. These activity levels are affected by both short- and long-term trends in oil and natural gas prices, among other factors.

Oil and natural gas prices and, therefore, the level of exploration, development and production activity, have experienced a high level of volatility leading to sustained declines from the highs in the latter half of 2014 to the lows that have continued through 2020.

A prolonged reduction in oil and natural gas prices or a sustained lack of key resources that affect drilling activity would generally depress the level of oil and natural gas exploration, development, production and well completion activity and would result in a corresponding decline in the demand for the proppants we produce and our wellsite proppant storage solutions. Such a decline would have a material adverse effect on our business, results of operation and financial condition. The commercial development of economically viable alternative energy sources (such as wind, solar, geothermal, tidal, fuel cells and biofuels) could have a similar effect. In addition, certain U.S. federal income tax deductions currently available with respect to oil and natural gas exploration and development may be eliminated. Any future decreases in the rate at which oil and natural gas reserves are discovered or developed, whether due to the passage of legislation, increased governmental regulation leading to limitations, or prohibitions on exploration and drilling activity, including hydraulic fracturing, or other factors, could have a material adverse effect on our business and financial condition, even in a stronger oil and natural gas price environment.



A substantial majority of our revenues have been generated under contracts with a limited number of customers, and the loss of, material nonpayment or nonperformance by or significant reduction in purchases by any of them could adversely affect our business, results of operations and financial condition.

As of January 1, 2021, we were contracted to sell frac sand produced from our Oakdale facility under three long-term take-or-pay contracts with a volume-weighted average remaining life of approximately 17 months. Because we have a small number of customers contracted under long-term take-or-pay contracts, these contracts subject us to counterparty risk. The ability or willingness of each of our customers to perform its obligations under a contract with us will depend on a number of factors that are beyond our control and may include, among other things, the overall operations and financial condition of the counterparty, the condition of the U.S. oil and natural gas exploration and production industry, continuing use of frac sand in hydraulic fracturing operations and general economic conditions. In addition, in depressed market conditions, our customers may no longer need the amount of frac sand for which they have contracted or may be able to obtain comparable products at a lower price. If our customers experience a significant downturn in their business or financial condition, they may attempt to renegotiate our contracts. For example, certain of our existing contracts were adjusted in 2020 resulting in a combination of reduced average selling prices per ton, adjustments to take-or-pay volumes and length of contract. We are also in litigation with one of our contracted customers over nonpayment of amounts due under its long term contract, which has since expired. If any of our major customers substantially reduces or altogether ceases purchasing our frac sand and we are not able to generate replacement sales of frac sand into the market, our business, financial condition and results of operations could be adversely affected until such time as we generate replacement sales in the market. In addition, as contracts expire, depending on market conditions at the time, our customers may choose not to extend these contracts which could lead to a significant reduction of sales volumes and corresponding revenues, cash flows and financial condition if we are not able to replace these contracts with new sales volumes. Additionally, even if we were to replace any lost contract volumes, lower prices for our product could materially reduce our revenues, cash flow and financial condition.

We are exposed to the credit risk of our customers, and any material nonpayment or nonperformance by our customers could adversely affect our business, results of operations and financial condition.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers. Our credit procedures and policies may not be adequate to fully eliminate customer credit risk. If we fail to adequately assess the creditworthiness of existing or future customers or unanticipated deterioration in their creditworthiness, any resulting increase in nonpayment or nonperformance by them and our inability to re-market or otherwise use the production could have a material adverse effect on our business, results of operations and financial condition. A decline in natural gas and crude oil prices could negatively impact the financial condition of our customers and sustained lower prices could impact their ability to meet their financial obligations to us. Further, our contract counterparties may not perform or adhere to our existing or future contractual arrangements. To the extent one or more of our contract counterparties is in financial distress or commences bankruptcy proceedings, contracts with these counterparties may be subject to renegotiation or rejection under applicable provisions of the United States Bankruptcy Code. Any material nonpayment or nonperformance by our contract counterparties due to inability or unwillingness to perform or adhere to contractual arrangements could adversely affect our business and results of operations.

We face significant competition that may cause us to lose market share.

The proppant industry is highly competitive. The proppant market is characterized by a small number of large, national producers and a larger number of small, regional or local producers. Competition in this industry is based on price, consistency and quality of product, site location, distribution and logistics capabilities, customer service, reliability of supply, breadth of product offering (including wellsite storage products and services) and technical support.

Some of our competitors have greater financial and natural other resources than we do. Also, certain of our competitors have recently emerged from bankruptcy and may be able to offer more attractive pricing as a result of lower debt obligations. In addition, our larger competitors may develop technology superior to ours or may have production facilities that offer lower-cost transportation to certain customer locations than we do. When the demand for hydraulic fracturing services decreases or the supply of proppant available in the market increases, prices in the frac sand market can materially decrease. Furthermore, oil and natural gas exploration and production companies and other providers of hydraulic fracturing services have acquired and in the future may acquire their own frac sand reserves to fulfill their proppant requirements, and these other market participants may expand their existing frac sand production capacity, all of which would negatively impact demand for our frac sand. In addition, increased competition in the proppant industry could have an adverse impact on our ability to enter into long-term contracts or to enter into contracts on favorable terms. For example, supplies of regional frac sand from our competitors became available in 2018, primarily in the Permian Basin of West Texas. These supplies have had a negative impact on our ability to sell our Northern White Sand in the Permian Basin or other markets in close proximity to these new mines. The reduced ability to sell sand in operating basins with regional sand supply has led to increased competition among our competitors in other basins and could lead to pressure to reduce prices to compete effectively.



We may be required to make substantial capital expenditures to maintain and grow our asset base. We may not realize enough of a return on such capital expenditures to cover their costs. Also, the inability to obtain needed capital or financing on satisfactory terms, or at all, could have an adverse effect on our business, results of operations and financial condition.

We rely on cash generated from our operations and the availability of credit to fund our capital expenditures. We have made significant capital expenditures, and expect to make additional capital expenditures in the future, particularly as it pertains to growing our SmartSystems last mile storage solution. We cannot provide any assurance that we will receive an adequate return on such capital expenditures.

In addition, our ability to maintain existing debt financing or to access the capital markets for future equity or debt offerings may be limited by our financial condition at the time of any such financing or offering, the covenants or borrowing base restrictions contained in our ABL Credit Facility or other current or future debt agreements, adverse market conditions or other contingencies and uncertainties that are beyond our control. Our failure to obtain the funds necessary to maintain, develop and increase our asset base could adversely impact our business, results of operations and financial condition.

Even if we are able to maintain existing financing or access the capital markets, incurring additional debt may significantly increase our interest expense and financial leverage, and our level of indebtedness could restrict our ability to fund future development and acquisition activities. In addition, the issuance of additional equity interests may result in significant dilution to our existing common stockholders.

Inaccuracies in estimates of volumes and qualities of our sand reserves could result in lower than expected sales and higher than expected cost of production.

We rely on our independent reserve engineers’ prepared estimates of our reserves based on engineering, economic and geological data assembled and analyzed by our engineers and geologists. 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 reserves and non-reserve frac sand deposits and costs to mine recoverable reserves, including many factors beyond our control. Estimates of economically recoverable frac sand reserves necessarily depend on a number of factors and assumptions, all of which may vary considerably from actual results, such as:

• geological and mining conditions and/or effects from prior mining that may not be fully identified by available data or that may differ from experience;

• 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 wetland mitigation requirements, the issuance of required permits and the assessment of taxes by governmental agencies.

Any inaccuracy in our independent reserve engineer’s estimates related to our frac sand reserves or non-reserve frac sand deposits could result in lower than expected sales or higher than expected costs. For example, estimates of our proven and probable recoverable sand reserves assume that our revenue and cost structure will remain relatively constant over the life of our reserves. If these assumptions prove to be inaccurate, some or all of our reserves may not be economically mineable, which could have a material adverse effect on our results of operations and cash flows. In addition, our current customer contracts require us to deliver frac sand that meets certain API and ISO specifications. If estimates of the quality of our reserves, including the volumes of the various specifications of those reserves, prove to be inaccurate, we may incur significantly higher excavation costs without corresponding increases in revenues, we may not be able to meet our contractual obligations, or our facilities may have a shorter than expected reserve life, any of which could have a material adverse effect on our results of operations and cash flows.

Our sand is generated at two facilities and our sales are dependent on delivery by railroads. Any adverse developments at our production facilities, rail terminals, or on any rail line could have a material adverse effect on our business, financial condition and results of operations.

All of our sand sales are currently derived from our facilities near Oakdale, Wisconsin and Utica, Illinois. We also ship a substantial portion of our sand through our rail terminals. Any adverse development at these facilities, our rail terminals, or on any of the rail lines we use to deliver our sand due to catastrophic events or weather, or any other event that would cause us to curtail, suspend or terminate operations at such facilities or terminals, could result in us being unable to meet our contracted sand deliveries. Although we have access to more than one Class I rail line, we may not be able to facilitate all shipments of product from one facility. We maintain insurance coverage to cover a portion of these types of risks; however, there are



potential risks associated with our operations not covered by insurance. There also may be certain risks covered by insurance where the policy does not reimburse us for all of the costs related to a loss. Downtime or other delays or interruptions to our operations that are not covered by insurance could have a material adverse effect on our business, results of operations and financial condition. In addition, under our long-term take-or-pay contracts, if we are unable to deliver contracted volumes and a customer arranges for delivery from a third party at a higher price, we may be required to pay that customer the difference between our contract price and the price of the third-party product.

## If we are unable to make acquisitions on economically acceptable terms, our future growth would be limited.

A portion of our strategy to grow our business is dependent on our ability to make acquisitions. If we are unable to make acquisitions from third parties because we are unable to identify attractive acquisition candidates or negotiate acceptable purchase contracts, we are unable to obtain financing for these acquisitions on economically acceptable terms or we are outbid by competitors, our future growth may be limited. Any acquisition involves potential risks, some of which are beyond our control, including, among other things:

• mistaken assumptions about revenues and costs, including synergies;

• inability to integrate successfully the businesses we acquire;

• inability to hire, train or retain qualified personnel to manage and operate our business and newly acquired assets;

• the assumption of unknown liabilities;

• limitations on rights to indemnity from the seller;

• mistaken assumptions about the overall costs of equity or debt;

• diversion of management’s attention from other business concerns;

• unforeseen difficulties operating in new product areas or new geographic areas; and

• customer or key employee losses at the acquired businesses.

If we consummate any future acquisitions, our capitalization and results of operations may change significantly, and common stockholders will not have the opportunity to evaluate the economic, financial and other relevant information that we will consider in determining the application of these funds and other resources.

## Restrictions in our ABL Credit Facility may limit our ability to capitalize on potential acquisition and other business opportunities.

The operating and financial restrictions and covenants in our ABL Credit Facility could restrict our ability to finance future operations or capital needs or to expand or pursue our business activities. For example, our ABL Credit Facility restricts or limits our ability to:

• grant liens;

• incur additional indebtedness;

• engage in a merger, consolidation or dissolution;

• enter into transactions with affiliates;

• sell or otherwise dispose of assets, businesses and operations;

• materially alter the character of our business as conducted at the time of filing of this annual report; and

• make acquisitions, investments and capital expenditures.

Furthermore, the borrowing base under our ABL Credit Facility is recalculated from time to time based on our eligible accounts receivable and inventory. Decreases in our eligible accounts receivable and inventory may limit our available borrowing levels and may require us to comply with certain financial ratios.



## We face distribution and logistical challenges in our business.

Transportation and logistical operating expenses comprise a significant portion of the costs incurred by our customers to deliver frac sand to the wellhead, which could favor suppliers located in close proximity to the customer. As oil and natural gas prices fluctuate, our customers may shift their focus to different resource plays, some of which may be located in geographic areas that do not have well-developed transportation and distribution infrastructure systems, or seek contracts with additional delivery and pricing alternatives including contracts that sell product on an “as-delivered” basis at the target shale basin. Serving our customers in these less-developed areas presents distribution and other operational challenges that may affect our sales and negatively impact our operating costs and any delays we experience in optimizing our logistics infrastructure or developing additional origination and destination points may adversely affect our ability to renew existing contracts with customers seeking additional delivery and pricing alternatives. Disruptions in transportation services, including shortages of railcars, lack of developed infrastructure, weather-related problems, flooding, drought, accidents, mechanical difficulties, strikes, lockouts, bottlenecks or other events could affect our ability to timely and cost effectively deliver to our customers and could temporarily impair the ability of our customers to take delivery and, in certain circumstances, constitute a force majeure event under our customer contracts, permitting our customers to suspend taking delivery of and paying for our frac sand (and in some cases terminating the agreement after a period of time). Additionally, increases in the price of transportation costs, including freight charges, fuel surcharges, transloading fees, terminal switch fees and demurrage costs, could negatively impact operating costs if we are unable to pass those increased costs along to our customers. Accordingly, because we are so dependent on rail infrastructure, if there are disruptions of the rail transportation services utilized by us or our customers, and we or our customers are unable to find alternative transportation providers to transport our products, our business and results of operations could be adversely affected. Further, declining volumes could result in a railcar over-capacity, which would lead to a railcar storage fees while, at the same time, we would continue to incur lease costs for those railcars in storage. Failure to find long-term solutions to these logistical challenges could adversely affect our ability to respond quickly to the needs of our customers or result in additional increased costs, and thus could negatively impact our business, results of operations and financial condition.

We may be adversely affected by decreased demand for frac sand due to the development of effective alternative proppants or new processes to replace hydraulic fracturing.

Frac sand is a proppant used in the completion and re-completion of oil and natural gas wells to stimulate and maintain oil and natural gas production through the process of hydraulic fracturing. Frac sand is the most commonly used proppant and is less expensive than other proppants, such as resin-coated sand and manufactured ceramics. A significant shift in demand from frac sand to other proppants, or the development of new processes to make hydraulic fracturing more efficient could replace it altogether, could cause a decline in the demand for the frac sand we produce and result in a material adverse effect on our business, results of operations and financial condition.

An increase in the supply of frac sand having similar characteristics as the frac sand we produce could make it more difficult for us to renew or replace our existing contracts on favorable terms, or at all.

If significant new reserves of frac sand are discovered and developed, and those frac sands have similar characteristics to the frac sand we produce, we may be unable to renew or replace our existing contracts on favorable terms, or at all. Specifically, if frac sand is oversupplied, our customers may not be willing to enter into long-term take-or-pay contracts, may demand lower prices or both, which could have a material adverse effect on our business, results of operations and financial condition. For example, new supplies of regional frac sand from our competitors became available in 2018, primarily in the Permian Basin of West Texas. These new supplies have had a negative impact on our ability to sell our Northern White Sand in the Permian Basin or other markets in close proximity to these new mines. Similarly, the COVID-19 pandemic has caused a historic slowdown in oil and gas activity, which has led to an increase in available proppant supply relative to the reduced demand. The foregoing have led to increased competition among our competitors and could lead to pressure to reduce prices to compete effectively, which could lead to pressure to further reduce prices to compete effectively.

A substantial portion of our accounts receivable consists of shortfall payments due from one customer under a long-term take-or-pay contract, which is currently subject to litigation.

A substantial portion of our accounts receivable consists of shortfall payments due from one customer under a long-term take-or-pay contract, which has since expired. We are currently in litigation with such customer regarding, among other things, nonpayment of shortfall amounts due. Litigation, by its nature, can be costly, time consuming, and unpredictable, and we can provide no assurance that the outstanding amounts due will be collected in a timely manner, if at all. As of December 31, 2020, $54.6 million of accounts receivable were from the foregoing customer.



Our operations are subject to operational hazards and unforeseen interruptions for which we may not be adequately insured.

Our operations are exposed to potential natural disasters, including blizzards, tornadoes, storms, floods, other adverse weather conditions and earthquakes. In addition, our employees could be subject to a COVID-19 outbreak at one or more of our facilities. If any of these events were to occur, we could incur substantial losses because of operational downtime, personal injury or loss of life, severe damage to and destruction of property and equipment, and pollution or other environmental damage resulting in curtailment or suspension of our operations.

We are not fully insured against all risks incident to our business, including the risk of our operations being interrupted due to severe weather and natural disasters. Furthermore, we may be unable to maintain or obtain insurance of the type and amount we desire at reasonable rates. As a result of market conditions, premiums and deductibles for certain of our insurance policies have increased and could escalate further. In addition, sub-limits have been imposed for certain risks. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we are not fully insured, it could have a material adverse effect on our business, results of operations and financial condition.

Our production process consumes large amounts of natural gas and electricity. An increase in the price or a significant interruption in the supply of these or any other energy sources could have a material adverse effect on our business, results of operations and financial condition.

Energy costs, primarily natural gas and electricity, represented approximately 4.6% of our total cost of goods sold for the year ended December 31, 2020. Natural gas is currently the primary fuel source used for drying in our frac sand production process. As a result, our profitability will be impacted by the price and availability of natural gas we purchase from third parties. Because we have not contracted for the provision of all of our natural gas usage on a fixed-price basis, our costs and profitability will be impacted by fluctuations in prices for natural gas. The price and supply of natural gas is unpredictable and can fluctuate significantly based on international, political and economic circumstances, as well as other events outside our control, such as changes in supply and demand due to weather conditions, actions by OPEC, governmental sanctions, and other oil and natural gas producers, regional production patterns, security threats and environmental concerns. In addition, potential climate change regulations or carbon or emissions taxes could result in higher cost of production for energy, which may be passed on to us in whole or in part. In order to manage the risk of volatile natural gas prices, we may hedge natural gas prices through the use of derivative financial instruments, such as forwards, swaps and futures. However, these measures carry risk (including nonperformance by counterparties) and do not in any event entirely eliminate the risk of decreased margins as a result of propane or natural gas price increases. We further attempt to mitigate these risks by including in our sales contracts fuel surcharges based on natural gas prices exceeding certain benchmarks. A significant increase in the price of energy that is not recovered through an increase in the price of our products or covered through our hedging arrangements or an extended interruption in the supply of natural gas or electricity to our production facilities could have a material adverse effect on our business, results of operations and financial condition.

Increases in the price of diesel fuel may adversely affect our business, results of operations and financial condition.

Diesel fuel costs generally fluctuate with increasing and decreasing world crude oil prices and, accordingly, are subject to political, economic and market factors that are outside of our control. Our operations are dependent on earthmoving equipment, locomotives and tractor trailers, and diesel fuel costs are a significant component of the operating expense of these vehicles. Accordingly, increased diesel fuel costs could have an adverse effect on our business, results of operations and financial condition.

A facility closure entails substantial costs, and if we close any of our facilities sooner than anticipated, our results of operations may be adversely affected.

We base our assumptions regarding the life of our facilities on detailed studies that we perform from time to time, but our studies and assumptions may not prove to be accurate. If we close any of our operating facilities sooner than expected, sales may decline. The closure of our operating facilities would involve significant fixed closure costs, including accelerated employment legacy costs, severance-related obligations, reclamation and other environmental costs and the costs of terminating long-term obligations, including energy contracts and equipment leases. We accrue for the costs of reclaiming open pits, stockpiles, non-saleable sand, ponds, roads and other mining support areas over the estimated mining life of our property. If we were to reduce the estimated life of our operating facilities, the fixed facility closure costs would be applied to a shorter period of production, which would increase the cost of production per ton produced and could materially and adversely affect our business, results of operations and financial condition.



Applicable statutes and regulations require that mining property be reclaimed following a mine closure in accordance with specified standards and an approved reclamation plan. The plan addresses matters such as removal of facilities and equipment, regrading, prevention of erosion and other forms of water pollution, re-vegetation and post-mining land use. We may be required to post a surety bond or other form of financial assurance equal to the cost of reclamation as set forth in the approved reclamation plan. The establishment of the final mine closure reclamation liability is based on estimated costs and requires various estimates and assumptions. If our accruals for expected reclamation and other costs associated with facility closures for which we will be responsible were later determined to be insufficient, our business, results of operations and financial condition may be adversely affected.

Our operations are dependent on our rights and ability to mine our properties and on our having renewed or received the required permits and approvals from governmental authorities and other third parties.

We hold numerous governmental, environmental, mining and other permits, water rights and approvals authorizing operations at our mining and operating facilities. For our extraction and processing in Wisconsin and Illinois, the permitting process is subject to federal, state and local authority. For example, on the federal level, a Mine Identification Request (MSHA Form 7000-51) must be filed and obtained before mining commences. If wetlands are impacted, a U.S. Army Corps of Engineers Wetland Permit is required. At the state level, a series of permits are required related to air quality, wetlands, water quality (waste water, storm water), grading permits, endangered species, archeological assessments and high capacity wells in addition to others depending upon site specific factors and operational detail. At the local level, zoning, building, storm water, erosion control, wellhead protection, road usage and access are all regulated and require permitting to some degree. A non-metallic mining reclamation permit is required. A decision by a governmental agency or other third party to deny or delay issuing a new or renewed permit or approval, or to revoke or substantially modify an existing permit or approval, could have a material adverse effect on our business, results of operations and financial condition.

Title to, and the area of, mineral properties and water rights may also be disputed. Mineral properties sometimes contain claims or transfer histories that examiners cannot verify. A successful claim that we do not have title to our property or lack appropriate water rights could cause us to lose any rights to explore, develop and extract minerals, without compensation for our prior expenditures relating to such property. Our business may suffer a material adverse effect in the event we have title deficiencies.

A shortage of skilled labor together with rising labor costs in the excavation industry may further increase operating costs, which could adversely affect our business, results of operations and financial condition.

Efficient sand excavation using modern techniques and equipment requires skilled laborers, preferably with several years of experience and proficiency in multiple tasks, including processing of mined minerals. If there is a shortage of experienced labor in areas in which we operate, we may find it difficult to hire or train the necessary number of skilled laborers to perform our own operations which could have an adverse impact on our business, results of operations and financial condition.

The manufacturing of our SmartSystems equipment requires skilled and experienced personnel who can perform physically demanding work. Our ability to operate the manufacturing facility in Saskatoon depends upon our ability to have access to the services of skilled workers. The demand for skilled workers is high, and the supply is limited. As a result, competition for experienced personnel is intense, and a significant increase in the wages paid by competing employers could result in a reduction of our skilled labor force, increases in the rates that we must pay or both. If either of these events were to occur, there could be an adverse impact on our business, results of operations and financial condition.

Our business may suffer if we lose, or are unable to attract and retain, key personnel.

We depend to a large extent on the services of our senior management team and other key personnel. Members of our senior management and other key employees bring significant experience to the market environment in which we operate. Competition for management and key personnel is intense, and the pool of qualified candidates is limited. The loss of any of these individuals or the failure to attract additional personnel, as needed, could have a material adverse effect on our operations and could lead to higher labor costs or the use of less-qualified personnel. In addition, if any of our executives or other key employees were to join a competitor or form a competing company, we could lose customers, suppliers, know-how and key personnel. We do not maintain key-man life insurance with respect to any of our employees. Our success is dependent on our ability to continue to attract, employ and retain highly skilled personnel.

Our profitability could be negatively affected if we fail to maintain satisfactory labor relations.

As of December 31, 2020, 28 employees in our Illinois facility operated under a collective bargaining agreement. If we are unable to renegotiate acceptable collective bargaining agreements with these employees in the future, we could experience, among other things, strikes, work stoppages or other slowdowns by our workers and increased operating costs as a result of



higher wages, health care costs or benefits paid to our employees. An inability to maintain good relations with our workforce could cause a material adverse effect on our business, financial condition, and results of operations.

Failure to maintain effective quality control systems at our mining, processing and production facilities could have a material adverse effect on our business, results of operations and financial condition.

The performance and quality of our products are critical to the success of our business. These factors depend significantly on the effectiveness of our quality control systems, which, in turn, depends on a number of factors, including the design of our quality control systems, our quality-training program and our ability to ensure that our employees adhere to our quality control policies and guidelines. Any significant failure or deterioration of our quality control systems could have a material adverse effect on our business, results of operations and financial condition.

Seasonal and severe weather conditions could have a material adverse impact on our business, results of operations and financial condition.

Our business could be materially adversely affected by severe weather conditions. Severe weather conditions may affect our customers' operations, thus reducing their need for our products, impact our operations by resulting in weather-related damage to our facilities and equipment and impact our customers' ability to take delivery of our products at our plant site. Any weather-related interference with our operations could force us to delay or curtail services and potentially breach our contractual obligations to deliver minimum volumes or result in a loss of productivity and an increase in our operating costs.

In addition, winter weather conditions impact our operations by causing us to reduce our excavation and wet plant related production activities during the winter months. During non-winter months, we excavate excess sand to build a stockpile that will feed the dry plants (along with the sand provided by our year-round wet plant), which continue to operate during the winter months. Unexpected winter conditions (such as winter arriving earlier than expected or lasting longer than expected) may result in us not having a sufficient sand stockpile to operate our dry plants during winter months, which could result in us being unable to deliver our contracted sand amounts during such time and lead to a material adverse effect on our business, results of operations and financial condition.

## Our cash flow fluctuates on a seasonal basis.

Our cash flow is affected by a variety of factors, including weather conditions and seasonal periods. Seasonal fluctuations in weather impact the production levels at our wet processing plant. While our sales and finished product production levels are contracted evenly throughout the year, our mining and wet sand processing activities are reduced during winter months. As a consequence, we experience lower cash costs in the first and fourth quarter of each calendar year.

We do not own the land on which our Van Hook, North Dakota terminal facility is located, which could disrupt our operations.

We do not own the land on which our Van Hook, North Dakota terminal is located and instead own a leasehold interest and right-of-way for the operation of this facility. Upon expiration, termination or other lapse of our current leasehold terms, we may be unable to renew our existing lease or right-of-way on terms favorable to us, or at all. Any renegotiation on less favorable terms or inability to enter into new leases on economically acceptable terms upon the expiration, termination or other lapse of our current lease or right-of-way could cause us to cease operations on the affected land, increase costs related to continuing operations elsewhere and have a material adverse effect on our business, financial condition and results of operations.

## A terrorist attack or armed conflict could harm our business.

Global and domestic terrorist activities, anti-terrorist efforts and other armed conflicts involving the United States could adversely affect the U.S. and global economies and could prevent us from meeting financial and other obligations. We could experience loss of business, delays or defaults in payments from payors or disruptions of fuel supplies and markets if pipelines, production facilities, processing plants, refineries or transportation facilities are direct targets or indirect casualties of an act of terror or war. Such activities could reduce the overall demand for oil and natural gas, which, in turn, could also reduce the demand for our frac sand. Global and domestic terrorist activities and the threat of potential terrorist activities and any resulting physical damage and economic downturn could adversely affect our results of operations, impair our ability to raise capital or otherwise adversely impact our ability to realize certain business strategies.

## Diminished access to water may adversely affect our operations or the operations of our customers.

The mining and processing activities at our facilities require significant amounts of water. Additionally, the development of oil and natural gas properties through fracture stimulation likewise requires significant water use. We have obtained water



rights that we currently use to service the activities at our operating facilities, and we plan to obtain all required water rights to service other properties we may develop or acquire in the future. However, the amount of water that we and our customers are entitled to use pursuant to water rights must be determined by the appropriate regulatory authorities in the jurisdictions in which we and our customers operate. Such regulatory authorities may amend the regulations regarding such water rights, increase the cost of maintaining such water rights or eliminate our current water rights, and we and our customers may be unable to retain all or a portion of such water rights. These new regulations, which could also affect local municipalities and other industrial operations, could have a material adverse effect on our operating costs and effectiveness if implemented. Such changes in laws, regulations or government policy and related interpretations pertaining to water rights may alter the environment in which we and our customers do business, which may negatively affect our financial condition and results of operations.

## We may be subject to interruptions or failures in our information technology systems, including cyber-attacks.

We rely on sophisticated information technology systems and infrastructure to support our business, including process control technology. Any of these systems may be susceptible to outages due to fire, floods, power loss, telecommunication failures, usage errors by employees, computer viruses, cyber-attacks or other security breaches, or similar events. If our information technology systems are damaged or cease to function properly, we may have to make a significant investment to fix or replace them, and we may suffer loss of critical data and interruptions or delays in our operations.

We may be the target of attempted cyber-attacks, computer viruses, malicious code, phishing attacks, denial of service attacks and other information security threats. To date, cyber-attacks have not had a material impact on our financial condition, results or business; however, we could suffer material financial or other losses in the future and we are not able to predict the severity of these attacks. The occurrence of a cyber-attack, breach, unauthorized access, misuse, computer virus or other malicious code or other cyber security event could jeopardize or result in the unauthorized disclosure, gathering, monitoring, misuse, corruption, loss or destruction of confidential and other information that belongs to us, our customers, our counterparties, or third-party service providers that is processed and stored in, and transmitted through, our computer systems and networks. The occurrence of such an event could also result in damage to our software, computers or systems, or otherwise cause interruptions or malfunctions in our, our customers', our counterparties' or third parties' operations. This could result in significant losses, loss of customers and business opportunities, reputational damage, litigation, regulatory fines, penalties or intervention, reimbursement or other compensatory costs, or otherwise adversely affect our business, financial condition or results of operations.

The reliability and capacity of our information technology systems is critical to our operations. Any material disruption in our information technology systems, or delays or difficulties in implementing or integrating new systems or enhancing current systems, could have an adverse effect on our business, and results of operations.

## If we are unable to fully protect our intellectual property rights, we may suffer a loss in our competitive advantage.

The commercial success of our SmartSystems wellsite proppant storage solutions depends on patented and proprietary information and technologies, know-how and other intellectual property. Because of the technical nature of this business, we rely on a combination of patent, copyright, trademark and trade secret laws, and restrictions on disclosure to protect our intellectual property. As of December 31, 2020, we had several patents related to our SmartSystems, including patents related to our silo storage system and patents related to lifting and lowering our storage silos. We customarily enter into confidentiality or license agreements with our employees, consultants and corporate partners and control access to and distribution of our design information, documentation and other patented and proprietary information. In addition, in the future we may develop or acquire additional patents or patent portfolios, which could require significant cash expenditures. However, third parties may knowingly or unknowingly infringe our patent or other proprietary rights, or challenge patents or proprietary rights held by us, and pending and future trademark and patent applications may not be approved. Failure to protect, monitor and control the use of our existing intellectual property rights could cause us to lose our competitive advantage and incur significant expenses. It is possible that our competitors or others could independently develop the same or similar technologies or otherwise obtain access to our unpatented technologies. In such case, our trade secrets would not prevent third parties from competing with us. Consequently, our results of operations may be adversely affected. Furthermore, third parties or our employees may infringe or misappropriate our patented or proprietary technologies or other intellectual property rights, which could also harm our business and results of operations. Policing unauthorized use of intellectual property rights can be difficult and expensive, and adequate remedies may not be available.

## We may be adversely affected by disputes regarding intellectual property rights of third parties.

Third parties from time to time may initiate litigation against us by asserting that the conduct of our business infringes, misappropriates or otherwise violates intellectual property rights. We may not prevail in any such legal proceedings related to such claims, and our storage systems and related items may be found to infringe, impair, misappropriate, dilute or otherwise violate the intellectual property rights of others. If we are sued for infringement and lose, we could be required to pay



substantial damages and/or be enjoined from using or selling the infringing products or technology. Any legal proceeding concerning intellectual property could be protracted and costly regardless of the merits of any claim and is inherently unpredictable and could have a material adverse effect on our financial condition, regardless of its outcome.

If we were to discover that our technologies or products infringe valid intellectual property rights of third parties, we may need to obtain licenses from these parties or substantially re-engineer our products in order to avoid infringement. We may not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to re-engineer our products successfully. If our inability to obtain required licenses for our technologies or products prevents us from selling our products, that could adversely impact our financial condition and results of operations.

We currently rely on a limited number of suppliers for certain equipment and materials to build our SmartSystems, and our reliance on a limited number of suppliers for such equipment and materials exposes us to risks including price and timing of delivery.

We currently rely on a limited number of suppliers for equipment and materials to build our SmartSystems. If demand for our systems or the components necessary to build such systems increases or suppliers of equipment face financial distress or bankruptcy, our suppliers may not be able to provide such equipment on schedule at the current price or at all. In particular, steel is the principal raw material used in the manufacture of our systems, and the price of steel has historically fluctuated on a cyclical basis and will depend on a variety of factors over which we have no control, including trade tariffs. Additionally, we depend on a limited number of suppliers for certain mechanical and electrical components that we use in our systems which may not have direct replacements available from alternate suppliers. If our suppliers are unable to provide the raw materials and components needed to build our systems on schedule at the current price or at all, we could be required to seek other suppliers for the raw materials and components needed to build and operate our systems, which may adversely affect our revenues or increase our costs. Any inability to find alternative components at prices or with quality specifications similar to those deployed today could result in delays or a loss of customers.

Unsatisfactory safety performance may negatively affect our customer relationships and, to the extent we fail to retain existing customers or attract new customers, adversely impact our revenues.

Our ability to retain existing customers and attract new business is dependent on many factors, including our ability to demonstrate that we can reliably and safely operate all aspects of our business in a manner that is consistent with applicable laws, rules and permits, which legal requirements are subject to change. In addition, certain customers require compliance with their internal safety protocols. Existing and potential customers consider the safety record of their third-party service providers to be of high importance in their decision to engage such providers. If one or more accidents were to occur in connection with our business, the affected customer may seek to terminate, cancel or substantially reduce its business with us, which could cause us to lose substantial revenues. Furthermore, our ability to attract new customers may be impaired if such potential customers elect not to engage us because they view our safety record as unacceptable. In addition, it is possible that we will experience multiple or particularly severe accidents in the future, causing our safety record to deteriorate. This may be more likely as we continue to grow, if we experience high employee turnover or labor shortage, or if we hire inexperienced personnel to bolster our staffing needs.

We may be subject to legal claims, such as personal injury and property damage, which could materially adversely affect our financial condition, prospects and results of operations.

As we focus on growing our business, particularly as it relates to our SmartSystems offerings, our business may become increasingly subject to inherent risks that can cause personal injury or loss of life, damage to or destruction of property, equipment or the environment or the suspension of our operations. In addition, we may be subject to legal proceedings with our customers or suppliers, particularly as it relates to contract disputes. Regardless of the merit of particular claims, litigation may be expensive, time consuming, disruptive to our operations and distracting to management.

The outcome of litigation is inherently uncertain. If one or more legal matters were resolved against us or an indemnified third party in a reporting period for amounts in excess of management’s expectations, our financial condition and operating results for that reporting period could be materially adversely affected. Further, such an outcome could result in significant compensatory, punitive or trebled monetary damages, disgorgement of revenue or profits, remedial corporate measures or injunctive relief against us that could materially adversely affect our financial condition and operating results. We maintain what we believe is customary and reasonable insurance to protect our business against these potential losses, but such insurance may not be adequate to cover our liabilities, and we are not fully insured against all risks.



A financial downturn could negatively affect our business, results of operations, financial condition and liquidity.

Actual or anticipated declines in domestic or foreign economic growth rates, regional or worldwide increases in tariffs or other trade restrictions, turmoil affecting the U.S. or global financial systems and markets and a severe economic contraction either regionally or worldwide, in each case resulting from current efforts to contain the COVID-19 coronavirus or other factors, could materially affect our business and financial condition. These events could impact our ability to finance operations by worsening the actual or anticipated future drop in worldwide oil demand, negatively impacting the price we receive for our products and services, compressing the level of available funding under our ABL Credit Facility, inhibiting our lenders from funding borrowings under our ABL Credit Facility or resulting in our lenders reducing the borrowing base under our ABL Credit Facility. Negative economic conditions could also adversely affect the collectability of our trade receivables or performance by our vendors and suppliers.

## Risks Related to our Recent Acquisition

Our acquisition of Eagle Oil and Gas Proppants Holdings LLC may not achieve its intended results, and we may be unable to successfully integrate the operations of Eagle Oil and Gas Proppants Holdings LLC.

On September 18, 2020, we entered into an equity purchase and sale agreement with Eagle pursuant to which we acquired all of the issued and outstanding interests in Eagle Proppants Holdings in exchange for aggregate consideration of approximately $2.1 million. In satisfaction of the purchase price, we issued to Eagle 1,503,759 shares of our common stock. The primary assets of Eagle Oil and Gas Proppants Holdings LLC and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the BNSF Class I rail line through the Peru, Illinois transload facility.

We expect that the acquisition of Eagle Proppants Holdings will result in various benefits, including, among other things, expanding our asset base. Achieving the anticipated benefits of the acquisition is subject to a number of uncertainties, including whether we can integrate the business of Eagle Proppants Holdings in an efficient and effective manner.

Our results of operations could be adversely affected by any issues attributable to Eagle Proppants Holdings’ operations that arise from or are based on events or actions that occurred prior to the closing of the acquisition, including unknown liabilities of Eagle Proppants Holdings or its subsidiaries. The integration process is subject to a number of uncertainties, and no assurance can be given whether anticipated benefits will be realized or, if realized, the timing of their realization. Failure to achieve these anticipated benefits could result in increased costs or decreases in the amount of expected revenues and could adversely affect our future business, financial condition, operating results, and prospects.

Our future results will suffer if we do not effectively manage our expanded operations.

With completion of the Eagle Proppants Holdings acquisition, our operations and the size of our business has expanded. Our future operating results depend, in part, on our ability to manage this expansion and growth successfully, which poses substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. We cannot assure you that we will be successful or that we will realize the expected operating efficiencies, cost savings, and other benefits from the acquisition that we currently anticipate. A failure to manage our growth effectively could materially and adversely affect our profitability.

## Risks Related to Environmental, Mining and Other Regulation

Federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing and the potential for related litigation could result in increased costs, additional operating restrictions or delays for our customers, which could cause a decline in the demand for our frac sand and negatively impact our business, results of operations and financial condition.

We supply frac sand to hydraulic fracturing operators in the oil and natural gas industry. Hydraulic fracturing is an important practice that is used to stimulate production of oil and natural gas from low permeability hydrocarbon bearing subsurface rock formations. The hydraulic fracturing process involves the injection of water, proppants, and chemicals under pressure into the formation to fracture the surrounding rock, increase permeability and stimulate production.

Although we do not directly engage in hydraulic fracturing activities, our customers purchase our frac sand for use in their hydraulic fracturing activities. Hydraulic fracturing is typically regulated by state oil and natural gas commissions and similar



agencies. Some states have adopted, and other states are considering adopting, regulations that could impose new or more stringent permitting, disclosure or well construction requirements on hydraulic fracturing operations. Aside from state laws, local land use restrictions may restrict drilling in general or hydraulic fracturing in particular. Municipalities may adopt local ordinances attempting to prohibit hydraulic fracturing altogether or, at a minimum, allow such fracturing processes within their jurisdictions to proceed but regulating the time, place and manner of those processes. In addition, federal agencies have started to assert regulatory authority over the process and various studies have been conducted or are currently underway by the EPA, and other federal agencies concerning the potential environmental impacts of hydraulic fracturing activities. At the same time, certain environmental groups have suggested that additional laws may be needed and, in some instances, have pursued voter ballot initiatives to more closely and uniformly limit or otherwise regulate the hydraulic fracturing process, and legislation has been proposed by some members of Congress to provide for such regulation.

The adoption of new laws or regulations at the federal, state or local levels imposing reporting obligations on, or otherwise limiting or delaying, the hydraulic fracturing process could make it more difficult to complete natural gas wells, increase our customers' costs of compliance and doing business, and otherwise adversely affect the hydraulic fracturing services they perform, which could negatively impact demand for our frac sand. In addition, heightened political, regulatory, and public scrutiny of hydraulic fracturing practices could expose us or our customers to increased legal and regulatory proceedings, which could be time-consuming, costly, or result in substantial legal liability or significant reputational harm. We could be directly affected by adverse litigation involving us, or indirectly affected if the cost of compliance limits the ability of our customers to operate. Such costs and scrutiny could directly or indirectly, through reduced demand for our frac sand, have a material adverse effect on our business, financial condition and results of operations.

We and our customers are subject to extensive environmental and occupational health and safety regulations that impose, and will continue to impose, significant costs and liabilities. In addition, future regulations, or more stringent enforcement of existing regulations, could increase those costs and liabilities, which could adversely affect our results of operations.

We are subject to a variety of federal, state, and local regulatory environmental requirements affecting the mining and mineral processing industry, including among others, those relating to employee health and safety, environmental permitting and licensing, air and water emissions, water pollution, waste management, remediation of soil and groundwater contamination, land use, reclamation and restoration of properties, hazardous materials, and natural resources. Some environmental laws impose substantial penalties for noncompliance, and others, such as the federal CERCLA, may impose strict, retroactive, and joint and several liabilities for the remediation of releases of hazardous substances. Liability under CERCLA, or similar state and local laws, may be imposed as a result of conduct that was lawful at the time it occurred or for the conduct of, or conditions caused by, prior operators or other third parties. Failure to properly handle, transport, store, or dispose of hazardous materials or otherwise conduct our operations in compliance with environmental laws could expose us to liability for governmental penalties, cleanup costs, and civil or criminal liability associated with releases of such materials into the environment, damages to property, natural resources and other damages, as well as potentially impair our ability to conduct our operations. In addition, future environmental laws and regulations could restrict our ability to expand our facilities or extract our mineral deposits or could require us to acquire costly equipment or to incur other significant expenses in connection with our business. Future events, including adoption of new, or changes in any existing environmental requirements (or their interpretation or enforcement) and the costs associated with complying with such requirements, could have a material adverse effect on us.

Any failure by us to comply with applicable environmental laws and regulations may cause governmental authorities to take actions that could adversely impact our operations and financial condition, including:

• issuance of administrative, civil, or criminal penalties;

• denial, modification, or revocation of permits or other authorizations;

• occurrence of delays in permitting or performance of projects;

• imposition of injunctive obligations or other limitations on our operations, including cessation of operations; and

• requirements to perform site investigatory, remedial, or other corrective actions.

Any such regulations could require us to modify existing permits or obtain new permits, implement additional pollution control technology, curtail operations, increase significantly our operating costs, or impose additional operating restrictions among our customers that reduce demand for our services.

We may not be able to comply with any new or amended laws and regulations that are adopted, and any new or amended laws and regulations could have a material adverse effect on our operating results by requiring us to modify our operations or equipment or shut down our facility. Additionally, our customers may not be able to comply with any new or amended laws and



regulations, which could cause our customers to curtail or cease operations. We cannot at this time reasonably estimate our costs of compliance or the timing of any costs associated with any new or amended laws and regulations, or any material adverse effect that any new or modified standards will have on our customers and, consequently, on our operations.

Silica-related legislation, health issues and litigation could have a material adverse effect on our business, reputation or results of operations.

We are subject to laws and regulations relating to human exposure to crystalline silica. Several federal and state regulatory authorities, including MSHA, may continue to propose changes in their regulations regarding workplace exposure to crystalline silica, such as permissible exposure limits and required controls and personal protective equipment. We may not be able to comply with any new or amended laws and regulations that are adopted, and any new or amended laws and regulations could have a material adverse effect on our operating results by requiring us to modify or cease our operations.

In addition, the inhalation of respirable crystalline silica is associated with the lung disease silicosis. There is evidence of an association between crystalline silica exposure or silicosis and lung cancer and a possible association with other diseases, including immune system disorders such as scleroderma. These health risks have been, and may continue to be, a significant issue confronting the proppant industry. Concerns over silicosis and other potential adverse health effects, as well as concerns regarding potential liability from the use of frac sand, may have the effect of discouraging our customers' use of our frac sand. The actual or perceived health risks of mining, processing and handling proppants could materially and adversely affect proppant producers, including us, through reduced use of frac sand, the threat of product liability or employee lawsuits, increased scrutiny by federal, state and local regulatory authorities of us and our customers or reduced financing sources available to the frac sand industry.

We are subject to the Federal Mine Safety and Health Act of 1977, which imposes stringent health and safety standards on numerous aspects of our operations.

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.

We and our customers are subject to other extensive regulations, including licensing, plant and wildlife protection and reclamation regulation, that impose, and will continue to impose, significant costs and liabilities. In addition, future regulations, or more stringent enforcement of existing regulations, could increase those costs and liabilities, which could adversely affect our results of operations.

In addition to the regulatory matters described above, we and our customers are subject to extensive governmental regulation on matters such as permitting and licensing requirements, plant and wildlife protection, wetlands protection, reclamation and restoration activities at mining properties after mining is completed, the discharge of materials into the environment, and the effects that mining and hydraulic fracturing have on groundwater quality and availability. Our future success depends, among other things, on the quantity and quality of our frac sand deposits, our ability to extract these deposits profitably, and our customers being able to operate their businesses as they currently do.

In order to obtain permits and renewals of permits in the future, we may be required to prepare and present data to governmental authorities pertaining to the potential adverse impact that any proposed excavation or production activities, individually or in the aggregate, may have on the environment. Certain approval procedures may require preparation of archaeological surveys, endangered species studies, and other studies to assess the environmental impact of new sites or the expansion of existing sites. Compliance with these regulatory requirements is expensive and significantly lengthens the time needed to develop a site. Finally, obtaining or renewing required permits is sometimes delayed or prevented due to community opposition and other factors beyond our control. The denial of a permit essential to our operations or the imposition of conditions with which it is not practicable or feasible to comply could impair or prevent our ability to develop or expand a site. Significant opposition to a permit by neighboring property owners, members of the public, or other third parties, or delay in the environmental review and permitting process also could delay or impair our ability to develop or expand a site. New legal requirements, including those related to the protection of the environment, could be adopted that could materially adversely affect our mining operations (including our ability to extract or the pace of extraction of mineral deposits), our cost structure, or our customers' ability to use our frac sand. Such current or future regulations could have a material adverse effect on our business, and we may not be able to obtain or renew permits in the future.



Our inability to acquire, maintain or renew financial assurances related to the reclamation and restoration of mining property could have a material adverse effect on our business, financial condition and results of operations.

We are generally obligated to restore property in accordance with regulatory standards and our approved reclamation plan after it has been mined. We are required under federal, state, and local laws to maintain financial assurances, such as surety bonds, to secure such obligations. The inability to acquire, maintain or renew such assurances, as required by federal, state, and local laws, could subject us to fines and penalties as well as the revocation of our operating permits. Such inability could result from a variety of factors, including:

• the lack of availability, higher expense, or unreasonable terms of such financial assurances;

• the ability of current and future financial assurance counterparties to increase required collateral; and

• the exercise by financial assurance counterparties of any rights to refuse to renew the financial assurance instruments.

Our inability to acquire, maintain, or renew necessary financial assurances related to the reclamation and restoration of mining property could have a material adverse effect on our business, financial condition, and results of operations.

Climate change legislation and regulatory initiatives could result in increased compliance costs for us and our customers.

In recent years, the U.S. Congress has considered legislation to reduce emissions of GHGs, including methane, a primary component of natural gas, and carbon dioxide, a byproduct of the burning of natural gas. It presently appears unlikely that comprehensive climate legislation will be passed by either house of Congress in the near future, although energy legislation and other regulatory initiatives are expected to be proposed that may be relevant to GHG emissions issues. In addition, a number of states are addressing GHG emissions, primarily through the development of emission inventories or regional GHG cap and trade programs. Depending on the particular program, we could be required to control GHG emissions or to purchase and surrender allowances for GHG emissions resulting from our operations. Independent of Congress, the EPA has adopted regulations controlling GHG emissions under its existing authority under the federal CAA. For example, following its findings that emissions of GHGs present an endangerment to human health and the environment because such emissions contributed to warming of the earth’s atmosphere and other climatic changes, the EPA has adopted regulations under existing provisions of the CAA that, among other things establish construction and operating permit reviews for GHG emissions from certain large stationary sources that are already potential major sources for conventional pollutants. In addition, the EPA has adopted rules requiring the monitoring and reporting of GHG emissions from specified production, processing, transmission and storage facilities in the United States on an annual basis. In addition, in December 2015, over 190 countries, including the United States, reached an agreement to reduce global GHG emissions, also known as the Paris Agreement. The Paris Agreement entered into force in November 2016 after more than 170 nations, including the United States, ratified or otherwise indicated their intent to be bound by the agreement. However, in June 2017, President Trump announced that the United States intends to withdraw from the Paris Agreement and to seek negotiations either to reenter the Paris Agreement on different terms or enter into a separate agreement. In August 2017, the U.S. Department of State officially informed the United Nations of the United States’ intent to withdraw from the Paris Agreement, and in November 2019 formally initiated the withdrawal process. In November 2020, the United States’ previously-announced withdrawal from the Paris Agreement became effective. On January 20, 2021, President Biden announced that the United States would be reentering the Paris Agreement. This reentry became effective on February 19, 2021. Several states and geographic regions in the United States have also adopted legislation and regulations to reduce emissions of GHGs, including cap and trade regimes and commitments to contribute to meeting the goals of the Paris Agreement. It is not possible at this time to predict the timing and effects of climate change or to predict the timing or effect of rejoining the Paris Agreement or whether additional climate-related legislation, regulations or other measures will be adopted at the local, state, regional, national and international levels. To the extent that the United States and other countries implement the Paris Agreement or local, state, regional, national or international governments impose other climate change regulations on the oil and natural gas industry, it could have an adverse effect on our business because substantial limitations on GHG emissions could adversely affect demand for the oil and natural gas that is produced by our customers. Finally, many scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, floods and other climatic events; if any such effects were to occur, they could have an adverse effect on our operations and our customers’ exploration and production operations.

## Risks Related to Ownership of Our Common Stock

Our stock price could be volatile, and you may not be able to resell shares of your common stock at or above the price you paid.

The stock markets generally have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common



stock. Volatility in the market price of our common stock may prevent you from being able to sell your common stock at or above the price at which you purchased the stock. As a result, you may suffer a loss on your investment. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. Such litigation, if instituted against us, could result in very substantial costs, divert our management’s attention and resources and harm our business, operating results and financial condition.

In addition to the risks described in this section, the market price of our common stock may fluctuate significantly in response to a number of factors, most of which we cannot control, including:

• our operating and financial performance;

• quarterly variations in the rate of growth of our financial indicators, such as revenues, EBITDA, Adjusted EBITDA, contribution margin, free cash flow, net income, and net income per share;

• the public reaction to our press releases, our other public announcements, and our filings with the SEC;

• strategic actions by our competitors;

• our failure to meet revenue or earnings estimates by research analysts or other investors;

• changes in revenue or earnings estimates, or changes in recommendations or withdrawal of research coverage, by equity research analysts;

• speculation in the press or investment community;

• the failure of research analysts to cover our common stock;

• sales of our common stock by us or our, stockholders, or the perception that such sales may occur;

• changes in accounting principles, policies, guidance, interpretations, or standards;

• additions or departures of key management personnel;

• actions by our stockholders;

• general market conditions, including fluctuations in commodity prices, sand-based proppants, or industrial and recreational sand-based products;

• domestic and international economic, legal and regulatory factors unrelated to our performance; and

• the realization of any risks described under this “Risk Factors” section.

We are subject to certain requirements of Section 404 of the Sarbanes-Oxley Act. If we are unable to timely comply with Section 404 or if the costs related to compliance are significant, our profitability, stock price, results of operations and financial condition could be materially adversely affected.

We are required to comply with certain provisions of Section 404 of the Sarbanes-Oxley Act. Section 404 requires that we document and test our internal control over financial reporting and issue management’s assessment of our internal control over financial reporting. This section also requires that our independent registered public accounting firm opine on those internal controls upon becoming a large accelerated filer, as defined in the SEC rules, or otherwise ceasing to qualify as an emerging growth company under the JOBS Act. We are evaluating our existing controls against the standards adopted by the Committee of Sponsoring Organizations of the Treadway Commission. During the course of our ongoing evaluation and integration of the internal control over financial reporting, we may identify areas requiring improvement, and we may have to design enhanced processes and controls to address issues identified through this review.

We believe that the out-of-pocket costs, diversion of management’s attention from running the day-to-day operations and operational changes caused by the need to comply with the requirements of Section 404 of the Sarbanes-Oxley Act could be significant. If the time and costs associated with such compliance exceed our current expectations, our results of operations could be adversely affected.

If we fail to comply with the requirements of Section 404 or if we or our independent registered public accounting firm identify and report such material weaknesses, the accuracy and timeliness of the filing of our annual and quarterly reports may be materially adversely affected and could cause investors to lose confidence in our reported financial information, which could have a negative effect on the stock price of our common stock. In addition, a material weakness in the effectiveness of our



internal control over financial reporting could result in an increased chance of fraud and the loss of customers, reduce our ability to obtain financing and require additional expenditures to comply with these requirements, each of which could have a material adverse effect on our business, results of operations and financial condition.

The concentration of our capital stock ownership among our largest stockholders and their affiliates will limit your ability to influence corporate matters.

As of December 31, 2020, Clearlake beneficially owns approximately 25.1% of our outstanding common stock and our Chief Executive Officer beneficially owns approximately 15.2% of our outstanding common stock. Consequently, Clearlake and our Chief Executive Officer (each of whom we sometimes refer to as a “Principal Stockholder”) will continue to have significant influence over all matters that require approval by our stockholders, including the election of directors and approval of significant corporate transactions. Additionally, we are party to a stockholders’ agreement pursuant to which, so long as either Principal Stockholder maintains certain beneficial ownership levels of our common stock, each Principal Stockholder will have certain rights, including board of directors and committee designation rights and consent rights, including the right to consent to change in control transactions. For additional information, please read “Certain Relationships and Related Party Transactions—Stockholders Agreement” in the prospectus included in our Registration Statement on Form S-1 (Registration No. 333-215554), initially filed with the SEC on January 13, 2017. This concentration of ownership and the rights of our Principal Stockholders under the stockholders agreement, will limit your ability to influence corporate matters, and as a result, actions may be taken that you may not view as beneficial.

Furthermore, conflicts of interest could arise in the future between us and Clearlake and its affiliates, including its portfolio companies, concerning among other things, potential competitive business activities or business opportunities. Clearlake is a private equity firm in the business of making investments in entities in a variety of industries. As a result, Clearlake’s existing and future portfolio companies which it controls may compete with us for investment or business opportunities. These conflicts of interest may not be resolved in our favor.

The price of our common stock may fluctuate significantly, and you could lose all or part of your investment.

As of December 31, 2020, there were 22,552,259 publicly traded shares of common stock held by our public common stockholders. Although our common stock is listed on the NASDAQ, we do not know whether an active trading market will continue to develop or how liquid that market might be. You may not be able to resell your common stock at or above the public offering price. Additionally, the lack of liquidity may result in wide bid-ask spreads, contribute to significant fluctuations in the market price of the common stock and limit the number of investors who are able to buy the common stock.

Our amended and restated certificate of incorporation contains a provision renouncing our interest and expectancy in certain corporate opportunities.

Our amended and restated certificate of incorporation provides for the allocation of certain corporate opportunities between us and Clearlake. Under these provisions, neither Clearlake, its affiliates and investment funds, nor any of their respective principals, officers, members, managers and/or employees, including any of the foregoing who serve as our officers or directors, will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. For instance, a director of our company who also serves or is a principal, officer, member, manager and/or employee of Clearlake or any of its affiliates or investment funds may pursue certain acquisitions or other opportunities that may be complementary to our business and, as a result, such acquisition or other opportunities may not be available to us. These potential conflicts of interest could have a material adverse effect on our business, financial condition and results of operations if attractive corporate opportunities are allocated by Clearlake to itself or its affiliates or investment funds instead of to us. The terms of our amended and restated certificate of incorporation are more fully described in “Description of Capital Stock” in the prospectus included in our Registration Statement on Form S-3 (Registration No. 333-251915), initially filed with the SEC on January 6, 2021.

If securities or industry analysts do not publish research or reports or publish unfavorable research about our business, the price and trading volume of our common stock could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades our securities, the price of our securities would likely decline. If one or more of these analysts ceases to cover us or fails to publish regular reports on us, interest in the purchase of our securities could decrease, which could cause the price of our common stock and other securities and their trading volume to decline.



Our amended and restated certificate of incorporation and amended and restated bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our common stock.

Our amended and restated certificate of incorporation authorizes our board of directors to issue preferred stock without stockholder approval. If our board of directors elects to issue preferred stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:

- advance notice provisions for stockholder proposals and nominations for elections to the board of directors to be acted upon at meetings of stockholders;

- provisions that divide our board of directors into three classes of directors, with the classes to be as nearly equal in number as possible;

- provisions that prohibit stockholder action by written consent after the date on which our Principal Stockholders collectively cease to beneficially own at least 50% of the voting power of the outstanding shares of our stock entitled to vote;

- provisions that provide that special meetings of stockholders may be called only by the board of directors or, for so long as a Principal Stockholder continues to beneficially own at least 20% of the voting power of the outstanding shares of our stock, such Principal Stockholder;

- provisions that provide that our stockholders may only amend our certificate of incorporation or bylaws with the approval of at least 66 2/3% of the voting power of the outstanding shares of our stock entitled to vote, or for so long as our Principal Stockholders collectively continue to beneficially own at least 50% of the voting power of the outstanding shares of our stock entitled to vote, with the approval of a majority of the voting power of the outstanding shares of our stock entitled to vote;

- provisions that provide that the board of directors is expressly authorized to adopt, or to alter or repeal our bylaws; and

- provisions that establish advance notice and certain information requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

We do not currently pay dividends on our common stock, and our debt agreements place certain restrictions on our ability to do so. Consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

We do not currently pay dividends on shares of our common stock in the foreseeable future. Additionally, our ABL Credit Facility places certain restrictions on our ability to pay cash dividends. Consequently, unless we revise our dividend policy, your only opportunity to achieve a return on your investment in us will be if you sell your common stock at a price greater than you paid for it. There is no guarantee that the price of our common stock that will prevail in the market will ever exceed the price that you previously paid.

Future sales of our common stock in the public market could reduce our stock price, and the sale or issuance of equity or convertible securities may dilute your ownership in us.

We may sell additional shares of common stock in subsequent public offerings. We may also issue additional shares of common stock or convertible securities. As of December 31, 2020, we have outstanding 43,461,141 shares of common stock. Clearlake beneficially owns 10,920,445 shares of our common stock, or approximately 25.1% of our total outstanding shares and our Chief Executive Officer beneficially owns 6,612,270 shares of our common stock, or approximately 15.2% of our total outstanding shares.

In connection with our initial public offering, we filed a registration statement with the SEC on Form S-8 providing for the registration of shares of our common stock issued or reserved for issuance under our equity incentive plans. Subject to the satisfaction of vesting conditions and the requirements of Rule 144, shares registered under the registration statement on Form S-8 will be available for resale immediately in the public market without restriction.



We have provided certain registration rights for the sale of common stock by certain existing stockholders in the future. The sale of these shares could have an adverse impact on the price of our common stock or on any trading market that may develop.

We cannot predict the size of future issuances of our common stock or securities convertible into common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our common stock.

We are an “emerging growth company” and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We intend to take advantage of these reporting exemptions until we are no longer an emerging growth company. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company for up to five years after our IPO, although we will lose that status sooner if we have more than $1.07 billion of revenues in a fiscal year, have more than $700 million in market value of our common stock held by non-affiliates as of any June 30 or issue more than $1.0 billion of non-convertible debt over a rolling three-year period.

Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

To the extent that we rely on any of the exemptions available to emerging growth companies, you will receive less information about our executive compensation and internal control over financial reporting than issuers that are not emerging growth companies.

We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock.

Our amended and restated certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our common stock respecting dividends and distributions, as our board of directors may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of the common stock.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (the “DGCL”), our amended and restated certificate of incorporation or our bylaws, or (iv) any action asserting a claim against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and consented to, the provisions of our amended and restated certificate of incorporation described in the preceding sentence. This choice of forum provision may limit a stockholder’s ability to bring a claim in a



judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

In addition to these currently operating facilities, we also recently acquired an idled mine and processing facility in New Auburn, Wisconsin as part of the Eagle Proppants Holdings acquisition, which contains a higher concentration of coarser sand deposits. We have no immediate plans to resume processing frac sand operations at this facility, though its administrative facilities and proximity to our Oakdale facility allow us to utilize the property to create synergies with our existing operations in Wisconsin.

We also own approximately 959 acres in Jackson County, Wisconsin (“Hixton”). The Hixton site is fully permitted to initiate operations and is available for future development. As of December 31, 2020, our Hixton site had approximately 100 million tons of proven recoverable sand reserves. We have no immediate plans to further develop this site.

We have two long-term surface mining leases for properties located in the Permian Basin in Texas that are available for future development. The first site consists of 1,772 acres in Winkler County, Texas. This location is adjacent to the Texas & New Mexico Railway (TXN) short line with direct access to State Highway 18. The second site consists of 2,447 acres in Crane County, Texas. This location has direct access to Interstate Highway 20. Based on our preliminary testing, we believe there are sufficient quantities on these sites to establish reserves in the future. We have no immediate plans to further develop these sites and have fully impaired capitalized improvements and development costs at these locations as of December 31, 2020.

We lease a 56,000 square foot facility in Saskatoon, Saskatchewan, Canada where we manufacture our SmartSystems wellsite proppant storage solutions.

We believe that our strategically-located mining sites provide us with a large and high-quality mineral reserves base. Mineral resources and reserves are typically classified by confidence (reliability) levels based on the level of exploration, consistency and assurance of geologic knowledge of the deposit. This classification system considers different levels of geoscientific knowledge and varying degrees of technical and economic evaluation. Mineral reserves are derived from in situ resources through application of modifying factors, such as mining, analytical, economic, marketing, legal, environmental, social and governmental factors, relative to mining methods, processing techniques, economics and markets. In estimating our reserves, we do not classify a resource as a reserve unless that resource can be demonstrated to have reasonable certainty to be recovered economically in accordance with the modifying factors listed above. “Reserves” are defined by SEC Industry Guide 7 as that part of a mineral deposit that could be economically and legally extracted or produced at the time of the reserve determination. Industry Guide 7 defines “proven (measured) reserves” as reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well-established. Industry Guide 7 defines “probable (indicated) reserves” as reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that size, shape, depth and mineral content of reserves are well-established.

In estimating our reserves, as listed in the tables above, we categorize our reserves as proven or probable recoverable in accordance with these SEC definitions. The quantity and nature of the sand reserves at our mining locations are estimated by third-party geologists and mining engineers, and we internally track the depletion rate on an interim basis. The recovery percentage following processing is also an important criterion in determining economic viability of our mineral reserves. We estimated an average processing recovery of approximately 68% at our Oakdale and Hixton locations and 77% at our Utica location.

Our Oakdale reserves are located on 1,256 contiguous acres in Monroe County, Wisconsin. We own our Monroe County acreage in fee and acquired surface and mineral rights on all of such acreage from multiple landowners in separate transactions. Our mineral rights are subject to an aggregate non-participating royalty interest of $0.50 per ton sold of coarser than 70 mesh, which we believe is significantly lower than many of our competitors.

Our Hixton site that is on approximately 959 acres in Jackson County, Wisconsin. The Hixton site is fully permitted and available for future development. We own our Jackson County acreage in fee and acquired surface and mineral rights on all of such acreage from multiple landowners in separate transactions. Our mineral rights are subject to an aggregate non-participating royalty interest of $0.50 per ton sold of coarser than 70 mesh, which we believe is significantly lower than many of our competitors.



Our Utica mine is approximately 1,400 acres in LaSalle County, Illinois. The Utica site is a fully owned including all mineral rights.

To opine as to the economic viability of our reserves, independent experts reviewed our financial cost and revenue per ton data at the time of the reserve determination. Historical mineral prices are considered in the context of market supply and demand dynamics to further assess the long-term economic viability of the mineral reserve assets that were evaluated over a thirty year measurement period. A range of average sales price assumptions was considered to estimate proven reserves in accordance with the Commission’s definitions. For our Oakdale location, the assumed average sales price was between $26 and $43 per ton over the course of the 30-year measurement period. For our Hxton location, the assumed average sales price was between $23 and $34 per ton over the course of the 30-year measurement period. The reserve estimates are updated annually based on a variety of factors, including sales, changes to mineral properties, changes in mine plan, current pricing forecasts and other business strategies. The recovery percentage following processing is also an important criterion in determining economic viability of our mineral reserves. An estimated average processing recovery of approximately 68% was used for our Oakdale and Hxton locations and 77% for our Utica location.

Based on their review of our cost structure and their extensive experience with similar operations, John T. Boyd concluded that it is reasonable to assume that we will operate under a similar cost structure over the remaining life of our reserves. John T. Boyd further assumed that if our revenue per ton remained relatively constant over the life of the reserves, our current operating margins are sufficient to expect continued profitability throughout the life of our reserves.

## ITEM 3. — LEGAL PROCEEDINGS

From time to time we may be involved in litigation relating to claims arising out of our operations in the normal course of business. The disclosure called for by Part I, Item 3 regarding our legal proceedings is incorporated by reference herein from Part II, Item 8. Note 17 - Commitments and Contingencies - Litigation of the notes to the consolidated financial statements in this Form 10-K for the year ended December 31, 2020.

## 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. — MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Shares of our common stock, traded publicly under the symbol, “SND,” have been publicly traded since November 4, 2016, when our common stock was listed and began trading on the NASDAQ Global Select Market (“NASDAQ”). Prior to that date, there was no public market for our stock.

## Holders of Record

On February 24, 2021, there were 43,410,521 shares of our common stock outstanding, which were held by approximately 27 stockholders of record. Because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

## Dividends

Our ability to pay dividends is governed by (i) the provisions of Delaware corporate law, (ii) our Certificate of Incorporation and Bylaws, and (iii) our ABL Credit Facility. To date, we have not paid or declared any dividends on our common stock and there is no assurance that we will pay any cash dividends on our common stock in the future. The future payment of cash dividends on our common stock, if any, is within the discretion of our board of directors and will depend on our earnings, capital requirements, financial condition, and other relevant factors.

## ITEM 7. — MANAGEMENT'S DISCUSSION AND ANALYSIS FINANCIAL CONDITION AND RESULTS OF OPERATIONS

## Forward-Looking Statements

The following discussion and analysis of our financial condition and results of operations should be read together with Item 1, “Business,” Item 6, “Selected Financial Data,” and the Consolidated Financial Statements and the related notes in Item 8 of this Annual Report on Form 10-K.

This discussion contains forward-looking statements as a result of many factors, including those set forth under Item 1, “Business—Forward-Looking Statements” and Item 1A, “Risk Factors,” and elsewhere in this report. These statements are based on current expectations and assumptions that are subject to risks and uncertainties. Actual results could differ materially from those discussed in or implied by forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report, particularly in Item 1A, “Risk Factors.”

We use EBITDA, Adjusted EBITDA, contribution margin and free cash flow herein as non-GAAP measures of our financial performance. For further discussion of EBITDA, Adjusted EBITDA, contribution margin and free cash flow, see the section entitled “Non-GAAP Financial Measures.” In Item 7 of this Annual Report on Form 10-K. We define various terms to simplify the presentation of information in this Report. All share amounts are presented in thousands.

## Factors Impacting Comparability of Our Financial Results

Our historical results of operations and cash flows are not indicative of results of operations and cash flows to be expected in the future, principally for the following reasons:

- Acquisition of Eagle Proppants Holdings. In September 2020, we acquired from Eagle Materials Inc., a Delaware corporation (“Eagle”), 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”). The primary assets of Eagle Proppants Holdings and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the BNSF Class I rail line through the Peru, Illinois transload facility. We began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020. We currently have no intention of operating the New Auburn, Wisconsin mine. 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.

- Increased supply and reduced demand. At the beginning of the second quarter of 2020, demand dropped dramatically as a result of the decline in oil prices to all-time lows caused by the COVID-19 coronavirus pandemic and a temporary increase in global oil supply driven by disagreements with respect to oil pricing between Russia and members of the Organization of the Petroleum Exporting Countries (“OPEC”), particularly Saudi Arabia. The COVID-19 coronavirus pandemic has caused a global decrease in all means of travel, the closure of borders between countries and a general slowing of economic activity worldwide which has decreased the demand for oil. In early March, discussions between Russia and Saudi Arabia deteriorated and the countries ended a three-year supply level agreement, which resulted in each country increasing its oil production. Subsequently, Russia and OPEC agreed to certain production cuts to mitigate the decline in the price of oil; however, such cuts may not be sufficient to stabilize the oil market over the long term if the decline in demand due to the COVID-19 coronavirus pandemic continues. Oil and natural gas prices are expected to continue to be volatile as a result of these events, and we cannot predict when prices will stabilize.

- Impairment loss. In 2020, we recorded an impairment loss of $5.1 million to fully write down the value of our long-lived assets in the Permian basin as we have no intentions to develop these properties in the foreseeable future. In 2019, we recorded impairment losses of $15.5 million, of which $7.6 million related to our finite-lived developed technology intangible assets and $7.9 million relates to our Hixon, Wisconsin property. In 2018, we recorded an impairment loss of $17.8 million, which related to our goodwill and indefinite-lived trade name intangible asset.

These amounts were recorded as an operating expense on the consolidated income statement. See our discussion in the section entitled “GAAP Results of Operations” for additional information regarding these transactions.

Market Trends. From early 2017 through the second quarter of 2018, improvements in oil and natural gas prices created a more stable market environment. During the second half of 2018, the demand for Northern White sand decreased, which we believe was due primarily to insufficient takeaway capacity for the incremental oil and natural gas production coming online in the Permian Basin, along with increased availability of regional sand as a source of proppant in the Permian basin. Additionally, oil and natural gas companies reduced their spending in the latter portion of the year due to strong spending in the first half of 2018 and lower oil prices, particularly in the fourth quarter of 2018. Demand briefly recovered during the summer of 2019 before declining toward the end of 2019 as oil and gas companies exhausted their budgets and managed their capital spending to be in line with their expected operating cash flows. During the first quarter of 2020, demand again briefly increased before declining as a result of the decline in oil prices to all-time lows caused by the COVID-19 coronavirus pandemic and an increase in global oil supply driven by disagreements with respect to oil pricing between Russia and members of OPEC. Supply side pressure has subdued while the effects of the COVID-19 coronavirus pandemic continue to drive reduced demand leading to volatility in oil prices.

Increased supply of sand coupled with lower oil demand has resulted in lower demand for our products and has led to reduced interest in long term contracts as customers are disinclined to enter into long-term contracts for their frac sand supply and have instead trended toward purchasing their frac sand supply in the spot market at market prices.

## Overview

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, sell our sand under a combination of long-term take-or-pay contracts and spot sales in the open market, and provide wellsite proppant storage solutions services and equipment under flexible contract terms custom tailored to meet customers' needs. 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 own and operate a frac sand mine and related processing facility near Oakdale, Wisconsin, at which we have approximately 315 million tons of proven recoverable sand reserves as of December 31, 2020. We incorporated in Delaware in July 2011 and began operations with 1.1 million tons of annual nameplate processing capacity in July 2012. After several expansions, our current annual processing capacity at our Oakdale facility is approximately 5.5 million tons of frac sand. Our integrated Oakdale facility, with on-site rail infrastructure and wet and dry sand processing facilities, has access to two Class I rail lines and enables us to process and cost-effectively deliver products to our customers.

In September 2020, we acquired from Eagle all of the issued and outstanding interests in Eagle Proppants Holdings. The primary assets of Eagle Proppants Holdings and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the BNSF Class I rail line through the Peru, Illinois transload facility. We began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020. We currently have no intention of operating the New Auburn, Wisconsin mine for the foreseeable future.

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. The Van Hook terminal became operational in April 2018. Since operations commenced, we have been providing Northern White sand in-basin at this terminal to our contracted and spot sales customers. This terminal allows us to offer more efficient delivery options to customers operating in the Bakken Formation in the Williston Basin.



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

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.

## Assets and Operations

## Oakdale, Wisconsin

Our sand reserves in Oakdale include a balanced concentration of coarse sand, (19% 20/40 and coarser), finer sand (41% of 40/70 mesh) and fine sand (40% 60/140 gradation, which we refer to in this annual report as “100 mesh”). Our 30/50 gradation is a derivative of the 20/40 and 40/70 blends. We believe that this mix of coarse and fine sand reserves, combined with contractual demand for our products across a range of mesh sizes, provides us with relatively higher mining yields and lower processing costs than frac sand mines with predominantly coarse sand reserves. In addition, our approximate 315 million tons of proven recoverable reserves implies a reserve life of approximately 57 years based on our current annual nameplate processing capacity of 5.5 million tons. This long reserve life enables us to better serve demand for different types of frac sand as compared to mines with shorter reserve lives.

Our Oakdale facility is purpose-built to exploit the reserve profile in place and produce high-quality frac sand. Unlike some of our competitors, our primary processing and rail loading facilities are located in close proximity to the mine site, which limits the need for us to truck sand on public roads between the mine and the production facility or between wet and dry processing facilities. Our on-site transportation assets include approximately nine miles of rail track in a triple-loop configuration and four railcar loading facilities that are connected to a Class I rail line owned by Canadian Pacific. This enables us to simultaneously accommodate multiple unit trains and significantly increases our efficiency in meeting our customers' frac sand transportation needs. Our unit train capable transload facility approximately three miles from the Oakdale facility in Byron Township, Wisconsin, provides us with the ability to ship sand to our customers on the Union Pacific rail network. We believe that we are the only sand facility in Wisconsin that has dual served rail capabilities, which should create competition among our rail carriers and allow us to provide more competitive logistics options for our customers.

## Utica & Peru, Illinois

Our Utica facility also has a large high-quality reserve base of primarily fine-mesh sand that is contiguous to the production facility and in close proximity to our Peru transload facility located on the BNSF railway. We have a minimum proven and probable reserve life of approximately 81 years based on our current annual processing capacity of 1.6 million tons at our Utica facility.

This recently acquired sand mine and processing facility adds significant logistics assets that further increases our logistics advantage, including access to BNSF, a Class I rail line, through our owned Peru transload facility. Additionally, the CSX and NS rail lines and barge access on the Illinois River to access the Mississippi River are available within short trucking distances. This facility is also capable of handling multiple unit trains simultaneously. These additional logistics options give us greater access to operating basins in the Western United States allowing us to offer more competitive pricing to existing and new customers in these markets.

## Logistics

Through our transloading terminal in Van Hook, North Dakota, we provide one of the most efficient and lowest-cost sources of Northern White sand in-basin to customers operating in the Bakken Formation in the Williston Basin.

Through our SmartSystems offering, we have the technology, production capacity and management team to compete further in the frac sand supply chain for our customers by offering logistics services from the mine all the way to the wellsite. Our SmartSystems consist of our SmartDepot proppant storage silos, transload technology, and rapid deployment trailer system.

We believe our patented SmartDepot silos will outperform our competitors in that they can be set up or taken down rapidly, they include industry-leading passive and active dust suppression technology, they have the capability of gravity-fed operation and they can be filled by both pneumatic and gravity dump trailers. Our trailers detach, which reduces their footprint on the wellsite. In 2020, we developed a self-contained SmartPath transloader, which 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



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

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 they 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.

Through the expansion of our SmartSystems fleet and other logistics options, we continue evaluating ways to reduce the landed cost of our products in-basin and to the wellsite for our customers while increasing our customized service offerings to provide additional delivery and pricing alternatives, including selling product on an “as-delivered” basis to the wellsite.

In 2020, we significantly expanded our existing logistics infrastructure through the acquisition of Eagle Proppants Holdings by adding new origination and destination points to our existing capabilities. We expect to continue to capitalize on our Oakdale facility’s ability to simultaneously accommodate multiple unit trains on-site with the Canadian Pacific rail network and ship on two Class I rail carriers to maximize our product shipment rates, increase our railcar utilization and lower our transportation costs. Through our transloading facility located on the Union Pacific rail network approximately three miles from our Oakdale facility, we have the ability to ship our frac sand directly to our customers on a second Class I rail carrier. Our newly acquired Peru transload terminal, located just minutes away from our Utica mine and frac sand processing facility, offers additional capability to ship products on a third Class I rail carrier, the BNSF. Additionally, the CSX and NS rail line and barge access on the Illinois River to access the Mississippi River are available within short trucking distances.

## How We Generate Revenue

We generate revenue by excavating and processing frac sand, which we sell to our customers under long-term price agreements or as spot sales at prevailing market rates. In some instances, revenues also include a charge for transportation services provided to customers. Our transportation revenue fluctuates based on a number of factors, including the volume of product transported and the distance between the plant and our customers. Our contracts contain a minimum volume purchase requirement and provide for delivery of frac sand from one of our processing facilities, our Van Hook transloading terminal in the Bakken, or another location specified by our customers. Revenue is generally recognized as products are delivered in accordance with the contract.

We generate revenue on our SmartSystems by renting equipment to our customers under contract terms tailored to meet the short-term or long-term needs with any number of SmartDepots, SmartPaths or trailers they require. We recognize rental revenue when the equipment is made available for the customer to use or other obligations in the contract are met.

## Costs of Conducting Our Business

The principal direct costs involved in operating our business are freight charges, which consist of transportation, railcar rental and storage, labor, maintenance, utility costs, equipment, excavation and depreciation of our property, plant and equipment. We incur labor costs associated with employees at our processing facility which represent the most significant cost of converting frac sand to finished product. Our sand processing and logistics facilities undergo maintenance to minimize unscheduled downtime and ensure the ongoing quality of our frac sand and ability to meet customer demands. We incur utility costs in connection with the operation of our processing and logistics facilities, primarily electricity and natural gas, which are both susceptible to market fluctuations. We lease equipment in many areas of our operations including our mining and hauling equipment and logistics services. Excavation costs relate to the blasting and excavation of sand and other materials in order to retrieve desirable sand products from which we derive revenue. In addition, other costs including processing costs, overhead allocation, depreciation and depletion are capitalized as a component of inventory and are reflected in cost of goods sold when inventory is sold.

## Overall Trends and Outlook

## Demand Trends

According to Spears, the North American proppant market, including frac sand, ceramic and resin-coated proppant, was approximately 46 million tons in 2020, which is approximately 50% decrease from the 94 million tons Spears reported for 2019. Spears estimates that 2021 demand will be flat with 2020 estimated demand.

## Supply Trends



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

There has been consolidation activity including mergers, acquisitions, closures of mines and bankruptcy filings among our peers. Additional consolidation activity is expected in 2021 in the mining, transloading and logistics businesses. Many large oil and natural gas exploration and production companies have continued to integrate vertically by sourcing their own proppant and some own their own sand mines.

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 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. 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, we’ve seen competitors in the Northern White frac sand market reduce their capacity by shuttering or idling operations as the shift to finer sands in hydraulic fracturing of oil and natural gas wells erodes the ongoing economic viability of producing coarser grades of sand.

## Management’s Outlook

We expect the demand for frac sand in 2021 to be flat or slightly increase from 2020 levels. Demand for both frac sand and our SmartSystems is influenced by the volume of oil and natural gas well drilling and completion activity, as well as the types of wells that are completed. Demand in 2020 was significantly impacted by oil oversupply by OPEC and reduced demand driven by COVID-19. The industry trends continue towards drilling and completing wells with longer laterals and more frac stages per lateral foot drilled. This trend is leading to higher volumes of sand per well and the need for oil and natural gas exploration companies to manage larger volumes of sand at the wellsite. We believe these trends support continued demand for frac sand and increased demand for SmartSystems as customers look to create synergies in the time and cost of managing their sand needs at the wellsite.

We generally expect the price of raw frac sand to fluctuate based on the level of drilling and completions activity for oil and natural gas as well as overall supply for frac sand relative to demand. In recent years, an increasing supply of sand has kept the price depressed. We believe the supply of sand to be stabilizing or contracting as consolidation in the industry continues. The willingness of exploration and production companies to engage in new drilling is determined by a number of factors, the most important of which are the prevailing and projected prices of oil and natural gas, the cost to drill, complete and operate a well, the availability and cost of capital and environmental and government regulations, as well as their ability to acquire the sand at the wellsite. We generally expect the level of drilling to correlate with long-term trends in commodity prices. Similarly, oil and natural gas production levels nationally and regionally generally tend to correlate with drilling activity.

## Revenue

Revenue was $122.3 million for the year ended December 31, 2020, during which we sold approximately 1,886,000 tons of sand. Revenue for the year ended December 31, 2019 was $233.1 million, during which we sold approximately 2,462,000 tons of sand. The key factors contributing to the decrease in revenues for the year ended December 31, 2020 as compared to the year ended December 31, 2019 were as follows:

- Sand sales revenue decreased from $109.6 million for the year ended December 31, 2019 to $70.9 million for the year ended December 31, 2020, as a result of lower total volumes sold. The volumes sold in 2020 were negatively impacted by depressed oil prices driven by continued oversupply relative to the decreased demand due to the COVID-19 coronavirus pandemic.

- We had $23.3 million of contractual shortfall revenue for the year ended December 31, 2020 and $49.3 million for the year ended December 31, 2019, respectively. Our contracts with customers 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. In 2020 and 2019, shortfall



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

revenue of $14.0 million and $24.8 million, respectively, was from a customer with which we have pending litigation.

- Logistics revenue, which includes freight for certain mine gate sand sales, railcar usage, logistics services and SmartSystems rentals, was $28.2 million for the year ended December 31, 2020, a decrease of $46.0 million when compared to logistics revenue of $74.2 million for the year ended December 31, 2019. The decrease in logistics revenue was due primarily to lower in basin sales due to the drop in demand caused by the COVID-19 coronavirus pandemic.

## Cost of Goods Sold

Cost of goods sold was $104.2 million and $152.0 million, for the years ended December 31, 2020 and December 31, 2019, respectively. Cost of goods sold decreased primarily due to expense reduction efforts put in place and due to lower production costs and freight expense from lower sales volumes due to lower demand caused by the COVID-19 coronavirus pandemic.

## Gross Profit

Gross profit was $18.1 million and $81.1 million for the years ended December 31, 2020 and December 31, 2019, respectively. The decrease in gross profit for the year ended December 31, 2020 was primarily due to lower total sales volumes and reduced shortfall revenue.

## Operating Expenses

Operating expenses were $31.1 million and $37.6 million for the years ended December 31, 2020 and December 31, 2019, respectively. Salaries, benefits and payroll taxes were reduced to $10.0 million for the year ended December 31, 2020, as compared to $11.6 million for the year ended December 31, 2019, respectively, as we reduced headcount and suspended certain variable cash compensation programs for all employees. Depreciation and amortization decreased from $2.4 million for the year ended December 31, 2019 to $1.9 million for the year ended December 31, 2020, primarily as a result of reduced amortization of certain intangible assets that were previously impaired in 2019. Selling, general and administrative expenses increased from $11.3 million for the year ended December 31, 2019 to $15.5 million for the year ended December 31, 2020, primarily as a result of increased professional fees related to ongoing litigation, acquisition costs related to our purchase of Eagle Proppants Holdings in the amount of $0.9 million and settlement of a multi-year sales tax audit in the amount of $1.3 million.

Operating expenses for the year ended December 31, 2020 included an impairment charge of $5.1 million related to the full impairment of long-lived assets in the Permian basin as we have no intentions to develop these properties in the foreseeable future. Operating expenses for year ended December 31, 2019 include an impairment charge of $7.6 million related to the Quickload system that we acquired in connection with our acquisition of Quickthree in 2018 and $7.9 million related to our Hixon, Wisconsin property in property, plant and equipment, net on the balance sheet. We had no plans to actively market the Quickload system, which resulted in the impairment charge. All developed technology intangible assets related to the Quickload system have been impaired of as of December 31, 2019.

## Gain on Bargain Purchase

For the year ended December 31, 2020, we recorded a gain on bargain purchase of $39.6 million related to our acquisition of Eagle Proppants Holdings. The gain was a result of the total fair value of net assets acquired in the transaction of $41.7 million, which exceeded the total consideration of $2.1 million paid to Eagle for such assets.

## Interest Expense

We incurred $2.1 million and $3.6 million of net interest expense for the years ended December 31, 2020 and 2019, respectively. The decrease in net interest expense for the year ended December 31, 2020 was primarily due to reduced interest rates on lower average total debt outstanding.

In 2019, we also recognized $0.6 million of costs due to the extinguishment of the Former Credit Facility. Our borrowings and total debt were reduced late in 2019 as a result of the payment in full and termination of the Former Credit Facility and our entry into the ABL Credit Facility.

## Income Tax (Benefit) Expense

Income tax benefit was $13.0 million for the year ended December 31, 2020 compared to income tax expense of $7.8 million for the year ended December 31, 2019. For the years ended December 31, 2020 and 2019, our effective tax rate was approximately (52.0)% and 19.8%, respectively, based on the annual effective tax rate net of discrete federal and state taxes. The computation of the effective tax rate for the years ended December 31, 2020 and December 31, 2019 included modifications from the statutory rate such as income tax credits, depletion deductions, carrybacks as a result of the Coronavirus Aid, Relief and Economic Security Act, and state apportionment changes, among other items. The bargain purchase gain related to our acquisition of Eagle Proppants Holdings that we recorded during the third quarter of 2020 is not taxable.

## Net Income

Net income was $38.0 million for year ended December 31, 2020 compared to $31.6 million for the year ended December 31, 2019. The increase in net income was primarily due to the gain on bargain purchase related to our acquisition of Eagle Proppants Holdings, current year income tax benefit and the impairment of intangible assets in the prior period, offset by the lower tons sold during 2020 driven largely by the COVID-19 coronavirus pandemic.

## Revenue

Revenue was $233.1 million for the year ended December 31, 2019, during which we sold approximately 2,462,000 tons of sand. Revenue for the year ended December 31, 2018 was $212.5 million, during which we sold approximately 2,995,000 tons of sand. Revenues increased for the year ended December 31, 2019 as compared to the year ended December 31, 2018 as a result of higher sales volumes and higher average selling prices.

The key factors contributing to the increase in revenues for the year ended December 31, 2019 as compared to the year ended December 31, 2018 were as follows:

- We had $49.3 million in contractual shortfall revenue for the year ended December 31, 2019 and $6.0 million for the year ended December 31, 2018, respectively. Our contracts with customers 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. In 2019, shortfall revenue of $24.8 million was from a customer with which we have pending litigation.

- Logistics revenue, which includes freight for certain mine gate sand sales, railcar usage, logistics services and SmartSystems rentals, was $74.2 million for the year ended December 31, 2019, an increase of $11.3 million when compared to logistics revenue of $62.9 million for the year ended December 31, 2018. The increase in logistics revenue was due to higher in-basin sales and rentals of our SmartSystems equipment. At December 31, 2019, we had four fleets of SmartSystems in the field.

- Sand sales revenue decreased to $109.6 million for the year ended December 31, 2019 compared to $143.1 million for the year ended December 31, 2018, primarily due to decreased sales volumes.

## Cost of Goods Sold

Cost of goods sold was $152.0 million and $143.1 million, or $61.75 and $47.78 per ton sold, for the years ended December 31, 2019 and December 31, 2018, respectively. Cost of goods sold increased in December 31, 2019 compared to December 31, 2018 primarily due to higher transportation costs as a result of increased in-basin sales volumes and increased depreciation and amortization due to our Oakdale expansion project being operational for the full year, partially offset by decreases in labor and equipment costs on lower total volumes sold.

## Gross Profit

Gross profit was $81.1 million and $69.4 million for the years ended December 31, 2019 and 2018, respectively. The increase in gross profit for the year ended December 31, 2019 was primarily due to higher shortfall and logistics revenue, partially offset by increased transportation costs as a result of increased in-basin sales volumes and lower total sales volumes.

## Operating Expenses

Operating expenses were $37.6 million and $41.7 million for the years ended December 31, 2019 and 2018, respectively. Operating expenses are primarily comprised of wages and benefits, professional services fees and other administrative expenses, all of which were relatively consistent year over year. Salaries, benefits and payroll taxes were $11.6 million and $11.0 million for the years ended December 31, 2019 and December 31, 2018, respectively. Selling, general and administrative expenses decreased from $12.8 million for the year ended December 31, 2018 to $11.3 million for the year ended December 31, 2019, primarily as a result of wellsite storage solution acquisition-related costs in the prior year. We recorded a decrease in the estimated fair value of contingent consideration related to our acquisition of Quickthree, which resulted in an offset to operating expenses in the amount of $3.3 million for the year ended December 31, 2019 and $1.9 million for the year ended December 31, 2018. In 2019, we recorded an impairment charge of $15.5 million of which $7.6 million related to our finite-lived developed technology intangible assets in intangible assets, net on the balance sheet and $7.9 million related to our Highton, Wisconsin property in property, plant and equipment, net on the balance sheet. The impairment of the finite-lived intangible assets is from our developed technology allocated to the Quickload acquired in connection with the acquisition of Quickthree in 2018. We have developed and tested a new transload technology and no longer plan to actively market the Quickload and as such, all developed technology intangible assets related to the Quickload were fully impaired during the third quarter of 2019. In the fourth quarter of 2019, we determined that the carrying amount of the Highton, Wisconsin property may not be fully



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

recoverable as we have no current plans to further develop the site. In the fourth quarter of 2018, we recorded an impairment charge of $17.8 million related to goodwill and an other indefinite-lived intangible asset. The impairment charge was primarily due to the decline in our stock price in 2018 and the relationship between the resulting market capitalization and the equity recorded on our balance sheet.

## Other Income (Expense)

We incurred $3.6 million and $2.3 million of net interest expense for the years ended December 31, 2019 and 2018, respectively. The increase in net interest expense for the year ended December 31, 2019 was primarily due to higher average borrowings under the Former Credit Facility to fund acquisition activities in 2018. In 2019, we also recognized $0.6 million of costs due to the extinguishment of the Former Credit Facility. Our borrowings and total debt were reduced late in 2019 as a result of the payment in full and termination of the Former Credit Facility and our entry into the ABL Credit Facility.

## Income Tax Expense

Income tax expense was $7.8 million for the year ended December 31, 2019 compared to a benefit of $5.5 million for the year ended December 31, 2018. For the years ended December 31, 2019 and 2018, our effective tax rate was approximately 19.8% and 21.5%, respectively, based on the statutory federal rate net of discrete federal and state taxes. The computation of the effective tax rate for the year ended December 31, 2019 and 2018 included modifications for income tax credits, among other items.

For the year ended December 31, 2018, we recorded a net operating loss for tax purposes due to the significant amount of capital expenditures we incurred, which were eligible for 100% expensing available under the Tax Reform Act. There are additional provisions in the Tax Reform Act that could impact us that will continue to be monitored as additional guidance is released and any necessary adjustments will be recorded in the period that the guidance is released.

## Net Income

Net income was $31.6 million for year ended December 31, 2019 compared to $20.1 million for the year ended December 31, 2018. The increase in net income was primarily due to higher shortfall revenue from customers that did not take their contractual minimum volumes of sand, higher logistics revenue from increased volumes shipped through our Van Hook terminal and rented SmartSystems equipment and lower impairment charges in 2019 compared to 2018.

## Non-GAAP Financial Measures

EBITDA, Adjusted EBITDA, contribution margin 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. Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA, gross profit is the GAAP measure most directly comparable to contribution margin 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 EBITDA, Adjusted EBITDA, contribution margin or free cash flow in isolation or as substitutes for an analysis of our results as reported under GAAP. Because EBITDA, Adjusted EBITDA, contribution margin 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.

## 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)

(UNAUDITED)

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.

(UNAUDITED)

Adjusted EBITDA was $20.5 million for the year ended December 31, 2020 compared to $87.1 million for the year ended December 31, 2019. The decrease in Adjusted EBITDA for the year ended December 31, 2020, as compared to the prior year, was primarily due to lower total volumes sold and decreased shortfall revenue in the current period.

Adjusted EBITDA was $87.1 million for the year ended December 31, 2019 compared to $67.8 million for the year ended December 31, 2018. The increase in Adjusted EBITDA for the year ended December 31, 2019, as compared to the prior year, was primarily due to higher shortfall and logistics revenue, partially offset by increased transportation charges and lower overall volumes of sand sold.

## Contribution Margin

We also 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. Contribution margin should not be considered an alternative to gross profit presented in accordance with GAAP. Because 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 contribution margin to gross profit.

<table><tr><td rowspan="3"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2020</td><td colspan="2">2019</td><td>2018</td></tr><tr><td colspan="4">(in thousands)</td></tr><tr><td>Revenue</td><td>$ 122,340</td><td>$ 233,073</td><td>$ 212,470</td><td></td></tr><tr><td>Cost of goods sold</td><td>104,221</td><td>152,021</td><td>143,103</td><td></td></tr><tr><td>Gross profit</td><td>18,119</td><td>81,052</td><td>69,367</td><td></td></tr><tr><td>Depreciation, depletion, and accretion of asset retirement obligations included in cost of goods sold</td><td>21,022</td><td>25,412</td><td>16,297</td><td></td></tr><tr><td>Contribution margin</td><td>$ 39,141</td><td>$ 106,464</td><td>$ 85,664</td><td></td></tr><tr><td>Contribution margin per ton</td><td>$ 20.75</td><td>$ 43.24</td><td>$ 28.60</td><td></td></tr><tr><td>Total tons sold</td><td>1,886</td><td>2,462</td><td>2,995</td><td></td></tr></table>

Contribution margin was $39.1 million, or $20.75 per ton sold, for the year ended December 31, 2020 compared to $106.5 million, or $43.24 per ton sold, for the year ended December 31, 2019. The decrease in overall contribution margin and contribution margin per ton sold for the year ended December 31, 2020, as compared to the prior year, was primarily due to lower volumes sold during the period and decreased shortfall revenue.

Contribution margin was $106.5 million, or $43.24 per ton sold, for the year ended December 31, 2019 compared to $85.7 million, or $28.60 per ton sold, for the year ended December 31, 2018. The increase in contribution margin and contribution margin per ton sold for the year ended December 31, 2019, as compared to the prior year, was primarily due to higher in-basin sales volumes through our Van Hook terminal and higher shortfall revenue.



## Free Cash Flow

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

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

<table><tr><td rowspan="2"></td><td colspan="4">Year Ended December 31,</td></tr><tr><td>2020</td><td>2019</td><td>2018</td><td></td></tr><tr><td></td><td colspan="4">(in thousands)</td></tr><tr><td>Net cash provided by operating activities</td><td>$ 25,541</td><td>$ 44,632</td><td>$ 50,909</td><td></td></tr><tr><td>Purchases of property, plant and equipment</td><td>(8,620)</td><td>(25,525)</td><td>(96,090)</td><td></td></tr><tr><td>Free cash flow</td><td>$ 16,921</td><td>$ 19,107</td><td>$ (45,181)</td><td></td></tr></table>

Free cash flow was $16.9 million for the year ended December 31, 2020 compared to $19.1 million for the year ended December 31, 2019. The decrease in free cash flow was attributable to lower total volumes sold as a result of the decreased demand due to the COVID-19 coronavirus pandemic. This decrease was offset by our reduction in our 2020 capital expenditure budget to align with slowdown of well completion activities by the exploration and production companies and oilfield service companies during 2020.

Free cash flow was $19.1 million for the year ended December 31, 2019 compared to negative free cash flow of $45.2 million for the year ended December 31, 2018. During the year ended December 31, 2018, we invested substantial capital expenditures to acquire the Van Hook terminal as well as a complete the expansion of our Oakdale facility.

## 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 December 31, 2020, cash on hand was $11.7 million and we had $9.5 million in undrawn availability on our ABL Credit Facility and $5.0 million in undrawn availability on the Acquisition Liquidity Support Facility.

As a result of the decline in the price of frac sand and instability in the market, we took steps to mitigate near term liquidity issues in 2020, including a reduction to our budgeted capital expenditures and cost cutting measures, including headcount reductions at our Oakdale and Saskatoon operating facilities and suspension of certain variable cash compensation programs.

Based on our balance sheet, cash flows, current market conditions, including the COVID-19 coronavirus pandemic, 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 December 31, 2020 compared to December 31, 2019.

<table><tr><td rowspan="3"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2020</td><td colspan="2">2019</td></tr><tr><td colspan="3">(in thousands)</td></tr><tr><td>Total current assets</td><td>$     112,086</td><td>$     92,177</td><td></td></tr><tr><td>Total current liabilities</td><td>37,263</td><td>40,018</td><td></td></tr><tr><td>Working capital</td><td>$     74,823</td><td>$     52,159</td><td></td></tr></table>

Our working capital was $74.8 million at December 31, 2020 compared to working capital of $52.2 million at December 31, 2019. The increase in working capital for the year ended December 31, 2020 was primarily due to cash collections and reductions in spending as certain vendor and lease contracts were modified. As of December 31, 2020 and 2019, $54.6 million and $37.4 million, respectively, of accounts receivable is attributable to a customer with which we have pending litigation.

## Summary Cash Flows

The following table sets forth a summary of our cash flows for the periods indicated:

## Net Cash Provided by Operating Activities

Net cash provided by operating activities was $25.5 million for the year ended December 31, 2020, which included income of $38.0 million, partially offset by non-cash items of $10.8 million, and $1.6 million in changes in operating assets and liabilities.



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

Net cash provided by operating activities was $44.6 million for the year ended December 31, 2019, which included net income of $31.6 million and net non-cash expenses of $47.8 million, partially offset by $34.8 million in changes in operating assets and liabilities.

Net cash provided by operating activities was $50.9 million for the year ended December 31, 2018, which included net income of $20.1 million and net non-cash expenses of $39.9 million, partially offset by $9.1 million in changes in operating assets and liabilities.

## Net Cash Used In Investing Activities

Net cash used in investing activities was $8.6 million for the year ended December 31, 2020, which was primarily for manufacturing of our SmartSystems.

Net cash used in investing activities was $25.4 million for the year ended December 31, 2019, of which $12.8 million was used to expand our SmartSystems operations and $12.7 million was used to expand our Van Hook terminal and capital improvements at our Oakdale facility.

Net cash used in investing activities was $126.0 million for the year ended December 31, 2018, of which approximately $45.5 million was used for our acquisitions of the Van Hook terminal and Quickthree, and the remainder of which was used for the completion of the Oakdale expansion project which began in 2017.

## Net Cash (Used in) Provided by Financing Activities

Net cash used in by financing activities was $7.9 million for the year ended December 31, 2020, which consisted primarily of $2.5 million of net repayments on our ABL Credit Facility, $4.0 million of net repayments for notes payable and finance leases, $1.2 million of share repurchases, and paid $0.3 million of payments of contingent consideration related to the manufacture of our SmartSystems equipment.

Net cash used in by financing activities was $18.0 million for the year ended December 31, 2019. In 2019, we repaid a net $42.0 million on our revolving credit facilities, paid $2.3 million of deferred financing and debt issuance costs and paid $2.0 million of contingent consideration, partially offset by receipt of $23.0 million in proceeds from the Oakdale Equipment Financing and $5.4 million of net proceeds from other notes payable.

Net cash provided by financing activities was $41.3 million for the year ended December 31, 2018, which was primarily related to net draws on our Former Credit Facility of $44.5 million, partially offset by repurchases of our common shares of $2.2 million and repayments of notes payable of $0.6 million.

## Oakdale Equipment Financing

On December 13, 2019, we entered into an equipment financing arrangement with Nexseer, secured by substantially all of the assets at our Oakdale facility. We received $23.0 million of net proceeds, of which we used $19.3 million to repay in



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

full and terminate our Former Credit Facility, $3.0 million for general working capital purposes and $0.7 million to pay transaction fees associated with the debt refinancing. The Oakdale Equipment Financing amortizes over 5 years and bears interest at 5.79%. A majority of the Oakdale Equipment Financing will mature on December 13, 2024 and the remaining portion will mature on March 31, 2025 due to financial relief provided as a result of the COVID-19 coronavirus pandemic in 2020.

## ABL Credit Facility

On December 13, 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 is based upon our eligible accounts receivable and inventory. The ABL Credit Facility contains various reporting requirements, negative covenants and restrictive provisions and requires maintenance of specified financial covenants under certain conditions, including a fixed charge coverage ratio, as defined in the ABL Credit Agreement. As of December 31, 2020 and 2019, the Company was in compliance with all covenants under the ABL Credit Facility. As of December 31, 2020, there were no amounts outstanding under the ABL Credit Facility, $0.7 million letters of credit and $9.5 million was available to be drawn. We use this facility primarily as a source for working capital needs. The weighted average interest rate on borrowings for the year ended December 31, 2020 was 3.31%.

## 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 with the 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. Beginning with the calendar quarter ending December 31, 2021, any amounts outstanding will amortize over the following three years. The facility bears interest at 6.00% during the draw period and 8.00% during the repayment period. There were no borrowings outstanding on this facility as of December 31, 2020.

## Capital Requirements

We expect full year 2021 capital expenditures to be between $10 million and $15 million, which are anticipated to primarily support incremental growth in our SmartSystems and to maintain 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.

## Share Repurchases

We are not currently authorized to repurchase additional shares. The previously authorized program terminated on September 11, 2020. The following table presents specified information about the Company’s repurchases of ordinary shares for the year ended December 31, 2020.

<table><tr><td rowspan="2"></td><td colspan="2">Year Ended</td></tr><tr><td colspan="2">December 31, 2020</td></tr><tr><td>Shares repurchased</td><td>778,300</td><td></td></tr><tr><td>Average price per share</td><td>$ 1.26</td><td></td></tr><tr><td>Aggregate repurchase cost (including broker costs)</td><td>$ 1.0 million</td><td></td></tr></table>

(UNAUDITED)

## Off-Balance Sheet Arrangements

We had $10.0 million and $7.9 million of outstanding performance bonds as of each of the years ended December 31, 2020 and 2019, respectively. These performance bonds assure our performance under our reclamation plan, maintenance and restoration of public roadways.

## Contractual Obligations

The following table presents our contractual obligations as of December 31, 2020:

<table><tr><td rowspan="2"></td><td rowspan="2">Total</td><td rowspan="2">Less than 1 year</td><td rowspan="2">1-3 years</td><td rowspan="2">3-5 years</td><td rowspan="2">More than 5 years</td></tr><tr><td>(in thousands)</td></tr><tr><td>Debt service</td><td>$ 34,087</td><td>$ 8,440</td><td>$ 15,686</td><td>$ 9,961</td><td>$ —</td></tr><tr><td>Operating leases</td><td>39,118</td><td>8,835</td><td>16,611</td><td>9,672</td><td>4,000</td></tr><tr><td>Asset retirement obligations</td><td>14,996</td><td>477</td><td>221</td><td>—</td><td>14,298</td></tr><tr><td>Land rights obligations</td><td>39,277</td><td>2,419</td><td>5,040</td><td>4,931</td><td>26,887</td></tr><tr><td>Total</td><td>$ 127,478</td><td>$ 20,171</td><td>$ 37,558</td><td>$ 24,564</td><td>$ 45,185</td></tr></table>

## 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.

## Customer Concentration

For the year ended December 31, 2020, Rice Energy (a subsidiary of EQT Corporation), Liberty, and U.S. Well Services accounted for 28.1%, 21.7%, and 14.0%, respectively, of total revenue. For the year ended December 31, 2019, Liberty, Rice Energy (a subsidiary of EQT Corporation), Hess Corporation, and U.S. Well Services accounted for 23.8%, 19.0%, 15.5%, and 14.7%, respectively, of total revenue. For the year ended December 31, 2018, Liberty, EQT, WPX Energy, and Hess accounted for 22.8%, 21.4%, 11.6%, and 10.6%, respectively, of total revenue.



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

## Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported revenues and expenses during the reporting periods. We evaluate these estimates and assumptions on an ongoing basis and base our estimates on historical experience, current conditions and various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Our actual results may materially differ from these estimates.

Listed below are the accounting policies we believe are critical to our financial statements due to the degree of uncertainty regarding the estimates or assumptions involved, and that we believe are critical to the understanding of our operations.

## Revenue Recognition

Revenues are recognized when control of the promised goods or services is transferred to our customers, the amount of which reflects the consideration we expect to be entitled to in exchange for those goods or services. Generally, sales are made at the origination point at our facility, and title passes as the product is loaded into railcars hired by the customer or provided by us. Deliveries of in-basin sand have shipping terms of FCA, DAT or DAP; and we recognize this revenue when the sand is delivered to the destination.

We derive our revenue by mining and processing sand that our customers purchase for various uses. Our revenues are primarily a function of the price per ton realized and the volumes sold. In some instances, our revenues also include transportation costs we charge to our customers, a monthly charge to reserve sand capacity and shortfall payments due from customers for minimum volume commitments. Our transportation revenue fluctuates based on a number of factors, including the volume of product we transport and the distance between our plant and our customers. Our reservation and shortfall revenue fluctuates based on individual contract terms.

We sell sand through short-term price agreements, at prevailing market rates, and long-term take-or-pay contracts. The expiration dates of these contracts range from 2021 through 2023. These agreements define, among other commitments, the volume of product that our customers must purchase, the volume of product that we must provide and the price that we will charge and that our customers will pay for each ton of contracted product.

SmartSystems revenues consist primarily of the rental of our patented SmartSystems equipment to customers, which is typically earned under fixed monthly fees, services related to delivery, proppant management and maintenance on the equipment. Revenues are recognized as the performance obligations are satisfied under the terms of the customer contract.

## Accounts and Unbilled Receivables

Accounts receivable represents customer transactions that have been invoiced as of the balance sheet date; unbilled receivables represent customer transactions that have not yet been invoiced as of the balance sheet date. Accounts receivable are due within 30 days, or in accordance with terms agreed upon with customers, and are stated at amounts due from customers net of any allowance for doubtful accounts. We consider accounts outstanding longer than the payment terms past due. We determine the allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history, the customer’s current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Accounts receivable are written off when they are deemed uncollectible, and payments subsequently received on such receivables are credited to bad debt expense. We have not had material allowances or bad debt expense

## Asset Retirement Obligation

We estimate the future cost of dismantling, restoring and reclaiming operating excavation sites and related facilities in accordance with federal, state and local regulatory requirements and recognize reclamation obligations when extraction occurs and record them as liabilities at estimated fair value. In addition, a corresponding increase in the carrying amount of the related



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

asset is recorded and depreciated over such asset’s useful life or the estimated number of years of extraction. The reclamation liability is accreted to expense over the estimated productive life of the related asset and is subject to adjustments to reflect changes in value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. Changes in estimates at inactive mines or mining areas are reflected in earnings in the period an estimate is revised. If the asset retirement obligation is settled for more or less than the carrying amount of the liability, a loss or gain will be recognized, respectively.

## Inventory Valuation

Sand inventory is stated at the lower of cost or net realizable value using the average cost method. Costs applied to inventory include direct excavation costs, processing costs, overhead allocation, depreciation and depletion. Stockpile tonnages are calculated by measuring the number of tons added and removed from the stockpile. Tonnages are verified periodically by a survey. Costs are calculated on a per ton basis and are applied to the stockpiles based on the number of tons in the stockpile.

Spare parts inventory includes critical spare parts. We account for spare parts on a first-in first-out basis, and value the inventory at the lower of cost or net realizable value.

## Leases

On January 1, 2019 we adopted ASU 2016-02, Leases (Topic 842), and related amendments, which replaced the existing guidance in ASC 840, Leases. ASU 2016-02 requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The lease standard does not substantially change lessor accounting.

Estimates used in the calculation of our operating lease liabilities include the incremental borrowing rate and lease options reasonably certain to be exercised. We determine our incremental borrowing rate based on an average of our actual collateralized borrowing rates offered by our lenders. We considered the nature of the assets and the life of the leases and determined that there is no significant difference in the incremental borrowing rate among differing classes of assets. There are no significant options that are reasonably certain to be exercised, residual value guarantees or restrictions or covenants in our lease contracts and, therefore, no such terms have been included in our accounting for the leases.

## Depletion

We amortize the cost to acquire land and mineral rights using a units-of-production method, based on the total estimated reserves and tonnage extracted each period.

## Impairment of Assets

In applying the acquisition method of accounting for business combinations, amounts assigned to identifiable assets and liabilities acquired were based on estimated fair values as of the date of acquisition, with the remainder recorded as goodwill. Intangible assets are initially valued at fair value using generally accepted valuation methods appropriate for the type of intangible asset. Intangible assets with definite lives are amortized over their estimated useful lives and are reviewed for impairment if indicators of impairment arise. As of and for the year ended December 31, 2020 we did not have goodwill or other indefinite lived intangibles assets on our balance sheet.

We periodically evaluate whether current events or circumstances indicate that the carrying value of our long-lived assets may not be recoverable. If circumstances indicate that the carrying value may not be recoverable, we estimate future undiscounted net cash flows, estimated future sales prices (considering historical and current prices, price trends and related factors) and anticipated operating costs and capital expenditures. If the carrying value of our long-lived assets is less than the undiscounted cash flows, the assets are measured at fair value and an impairment is recorded if that fair value is less than the carrying value.

During the year ended December 31, 2020, we recorded an impairment charge of $5.1 million related to the full impairment of long-lived assets in the Permian basin as we have no intentions to develop these properties in the foreseeable future. During the year ended December 31, 2019, we recorded impairment loss of $15.5 million, of which $7.6 million relates to our finite-lived developed technology intangible assets and $7.9 million relates to our Hixton, Wisconsin property. The impairment of the finite-lived intangible assets is from our developed technology allocated to the Quickload acquired in connection with the acquisition of Quickthree in 2018.



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

We recorded an impairment charge of $17.8 million related to goodwill and an other indefinite-lived intangible asset for the year ended December 31, 2018, all of which was driven by the decline in our stock price in 2018 and the relationship between the resulting market capitalization and the equity recorded on our balance sheet.

## Income Taxes

Under the balance sheet approach to provide for income taxes, we recognize deferred tax assets and liabilities for the expected future tax consequences of net operating loss carryforwards and temporary differences between the carrying amounts and the tax bases of assets and liabilities. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which those temporary differences become deductible. If we determine it is more likely than not that we will not be able to realize the benefits of the deductible temporary differences, we would record a valuation allowance against the net deferred tax asset.

We recognize the impact of uncertain tax positions at the largest amount that, in our judgment, is more-likely-than-not to be required to be recognized upon examination by a taxing authority.

## Stock-Based Compensation

Stock-based compensation expense is recorded based upon the fair value of the award at grant date. Such costs are recognized as expense over the corresponding requisite service period. We use the actual public market price of our shares or an adjusted price using a Monte Carlo simulation for awards subject to the Company’s performance as compared to a defined peer group as the grant date fair value for restricted stock awards.

The following is a summary of the restricted stock awards granted and the related grant date fair value in the years ended December 31, 2020, 2019 and 2018.

<table><tr><td></td><td>Number of Shares Granted (in thousands)</td><td>Weighted Average Grant Date Fair Value</td></tr><tr><td>For the year ended December 31, 2020</td><td>—</td><td>$ —</td></tr><tr><td>For the year ended December 31, 2019</td><td>1,884</td><td>$ 2.58</td></tr><tr><td>For the year ended December 31, 2018</td><td>746</td><td>$ 6.61</td></tr></table>

## Emerging Growth Company

We qualify as an “emerging growth company” pursuant to the provisions of the JOBS Act, enacted on April 5, 2012. Section 102 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. However, we are choosing to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Our election to “opt-out” of the extended transition period is irrevocable.

## Recent Accounting Pronouncements

In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC’s regulations. We will adopt ASU 2020-10 as of the reporting period beginning January 1, 2021. The adoption of this update is not expected to have a material effect on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which intends to simplify the guidance by removing certain exceptions to the general principles and clarifying or amending existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Although we are currently evaluating the impact of the adoption of ASU 2019-12, we do not expect it to have a material impact on our consolidated financial statements.

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



# MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(UNAUDITED)

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 our Company for financial statement periods beginning after December 15, 2022, although early adoption is permitted. While we are 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, we believe the primary effect will be any applicable allowance recorded against our accounts and unbilled receivables on our balance sheet and related expense on our income statement at that time. We cannot determine the financial impact on our consolidated financial statements upon adoption as our accounts and unbilled receivables balances are affected by ongoing transactions with customers.



## ITEM 7A. — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of loss arising from adverse changes in market rates and prices. Historically, our risks have been predominantly related to potential changes in the fair value of our long-term debt due to fluctuations in applicable market interest rates. Going forward our market risk exposure generally will be limited to those risks that arise in the normal course of business, as we do not engage in speculative, non-operating transactions, nor do we utilize financial instruments or derivative instruments for trading purposes. We do not believe that inflation has a material impact on our financial position or results of operations during periods covered by the financial statements included in this filing.

## Commodity Price Risk

The market for proppant and proppant storage equipment is indirectly exposed to fluctuations in the prices of crude oil and natural gas to the extent such fluctuations impact drilling and completion activity levels and thus impact the activity levels of our customers in the oilfield services and exploration and production industries. We do not currently intend to hedge our indirect exposure to commodity price risk.

## Interest Rate Risk

The majority of our debt is financed under fixed interest rates. Borrowings under the ABL Credit Facility bear interest at a rate per annum equal to an applicable margin, plus, at our option, either a LIBOR rate or an alternate base rate (“ABR”). The applicable margin is 2.00% for LIBOR loans and 1.00% for ABR loans. There was no balance on our ABL Credit Facility as of December 31, 2020. We do not believe this represents a material interest rate risk.

## Credit Risk

A substantial portion of our revenue for the year ended December 31, 2020 was generated through long-term take-or-pay contracts with six customers. Our customers are oil and natural gas producers and oilfield service providers, all of which have been negatively impacted by the downturn in activity in the oil and natural gas industry beginning in the latter part of 2018 and continuing through much of 2019 and 2020. This concentration of counterparties operating in a single industry may increase our overall exposure to credit risk, in that the counterparties may be similarly affected by changes in economic, regulatory or other conditions. If a customer defaults or if any of our contracts expire in accordance with its terms, and we are unable to renew or replace these contracts or the related sales volumes, our gross profit and cash flows may be adversely affected.

Additionally, as of December 31, 2020 and 2019, $54.6 million and $37.4 million, respectively, of accounts and unbilled receivables is attributable a customer with which we have pending litigation. We are unable to express an opinion as to the likely outcome of the matter, and even if we are successful, we can make no assurances that they will be able to pay.

## Foreign Currency Risk

Our revenues and expenses are primarily in United States dollars; however, as a result of our acquisition of Quickthree on June 1, 2018, certain transactions are transacted in Canada dollars. Thus, revenues, operating expenses, the results of operations, assets and liabilities may be impacted to the extent that they are not hedged by the rise and fall of the relative value of the United States dollar to the Canada dollar. During the years ended December 31, 2020, 2019 and 2018, revenue, expenses, assets and liabilities transacted in Canada dollars were immaterial to the results of operations.

Board of Directors and Stockholders
Smart Sand, Inc.

## Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Smart Sand Inc. (a Delaware corporation) and subsidiaries (the "Company") as of December 31, 2020 and 2019, the related consolidated income statements, and consolidated statements of comprehensive income, changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

## Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

The Company completed construction of the first phase of its mine and processing facility near Oakdale, Wisconsin and commenced operations in July 2012, and subsequently expanded its operations in 2014, 2015 and 2018. Currently the Company’s annual processing capacity is approximately 5.5 million tons.

In March 2018, the Company acquired the rights to operate a unit train capable transloading terminal in Van Hook, North Dakota to service the Bakken Formation in the Williston Basin and began providing Northern White Sand in-basin in April 2018.

In June 2018, the Company acquired substantially all of the assets of Quickthree Solutions, Inc., (“Quickthree”) a manufacturer of portable vertical proppant storage solution systems. Quickthree formed the basis for the Company’s SmartSystems under which it offers various proppant storage solutions that create efficiencies, flexibility, enhanced safety and reliability for customers by providing the capability to unload, store and deliver proppant at the wellsite, as well as the ability to rapidly set up, takedown and transport the entire system. The SmartDepot \( ^{™} \)  silo includes passive and active dust suppression technology, along with the capability of gravity-fed operation. The self-contained SmartPath \( ^{™} \)  transloader is a mobile sand transloading system designed to work with bottom dump trailers and features a drive over conveyor, surge bin, and dust collection system. 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 Tracker \( ^{™} \) , allows customers to monitor silo-specific information, including location, proppant type and proppant inventory.

In September 2020, the Company acquired from Eagle Materials Inc., a Delaware corporation (“Eagle”), 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”). The primary assets of Eagle Proppants Holdings and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the Burlington Northern Sante Fe (“BNSF”) Class I rail line through the Peru, Illinois transload facility. The Company began operating the Utica, Illinois mine and Peru, Illinois transload facility in October 2020.

## NOTE 2 — Summary of Significant Accounting Policies

## Basis of Presentation and Consolidation

The accompanying consolidated financial statements (“financial statements”) of the Company have been prepared in accordance with GAAP and pursuant to the rules and regulations of the SEC. The accompanying financial statements include those of our controlled subsidiaries. The intercompany accounts and transactions have been eliminated. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these financial statements have been included.

## 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 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, goodwill 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 from management’s best estimates as additional information or actual results become available in the future, and those differences could be material. The increased supply of oil and the decreased demand related to the COVID-19 coronavirus pandemic have caused a dramatic decline in oil prices and significant volatility in the oilfield service sector. 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.

## Revision of Previously Issued Financial Statements for Immaterial Misstatements

During the quarter ended June 30, 2020, the Company identified an error in costs of goods sold in the Company’s audited financial statements for the year ended December 31, 2018. The error related to a vendor rebate the Company received during the current period, $1,800 of which related to expenses attributable to fiscal year 2018. As a result of the error, the Company reduced costs of goods sold by $1,800 and increased income tax expense by $387 resulting in an increase in net income of $1,413 and increase of $0.03 in both basic and diluted earnings per share in the Company’s audited financial statements for the year ended December 31, 2018. Retained earnings increased by $1,413 in the Company’s audited financial statements for the year ended December 31, 2019. Additionally, certain 2019 balance sheet items have been reclassified to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income.

Pursuant to the guidance of Staff Accounting Bulletin (“SAB”) No. 99, “Materiality”, the Company evaluated the materiality of these errors quantitatively and qualitatively and concluded that the errors described above were not material to any of its prior annual or quarterly financial statements or trends of financial results. However, due to reduced activity and the current economic environment, the errors could be considered material to the Company’s current period financial statements. As such, the Company has revised the prior period financial statements in accordance with SAB No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.” The Company revised previously presented historical financial statements for these immaterial errors in the annual audited financial statements included in this Annual Report on Form 10-K.

## Revenue Recognition

Revenues are generally recognized when control of the promised goods or services is transferred to our customers, the amount of which reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

## Sand Sales Revenue

The Company derives its sand sales revenue by mining and processing sand. Its revenues are primarily a function of the price per ton realized and the volumes sold. For sand delivered FCA at the origination point at the Company’s facility, title passes as the product is loaded into railcars hired by the customer or provided by the Company and revenue is recognized when title transfers at the Company’s facility. For sand delivered in-basin, the Company recognizes the revenue when title passes at the destination. The amount invoiced reflects product, transportation and any other additional handling services, such as storage or transloading the product from railcar to truck.

Prices under the Company’s long-term agreements with customers are generally indexed to the Average Cushing Oklahoma WTI Spot Prices and contain provisions allowing for adjustments including: (i) annual percentage price increases; and/or (ii) market factor adjustments, including a natural gas surcharge/reduction and a propane surcharge/reduction which are applied if the Average Natural Gas Price or the Average Quarterly Mont Belvieu TX Propane Spot Price, respectively, as listed by the U.S. Energy Information Administration, are above or below the applicable benchmark set forth in the contract for the preceding calendar quarter.

The Company requires certain customers to pay a fixed-price monthly reservation charge based on a minimum contractual volume over the remaining life of their contract, which may be applied as a per ton credit to the sales price up to a certain contractually specified monthly volume or credited against any applicable shortfall payments. The Company recognizes revenue when the customer no longer has the right to use the reservation charge towards sand sales or shortfall payments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

# (IN THOUSANDS, EXCEPT PER SHARE DATA)

## Shortfall Revenue

The Company’s shortfall revenues are related to minimum commitments under take-or-pay contracts and based on negotiated contract terms and are recognized when rights of use are expired. The Company recognizes revenue to the extent of the unfulfilled minimum contracted quantity at the shortfall price per ton as stated in the contract.

## Logistics Revenue

Logistics revenue includes railcar usage revenue, transportation revenue and SmartSystems revenue.

Railcar usage revenue consists of revenue derived from the usage of the Company’s railcars by customers under long-term contracts or on an as-used basis. Based on the customer contract, the Company either recognizes revenue on the usage of railcars based on when the terms of the agreement state that the railcar is available to the customer for use, or based on a specified price per ton shipped.

Transportation revenue consists primarily of railway transportation and transload services to deliver products to customers. The Company’s transportation revenue fluctuates based on many factors, including the volume of product it transports and the distance between its plant and customers.

SmartSystems revenues consists primarily from the rental of our patented SmartSystems equipment to customers, which is typically earned under fixed monthly fees and services related to delivery, proppant management and maintenance on the equipment. Revenues are recognized as the performance obligations are satisfied under the terms of the customer contract.

## Contract Balances

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, deferred revenue, and contract assets, included in other assets, on the consolidated balance sheet. For the Company’s sand sales, amounts are billed as sand is loaded on the railcars to fill customer orders for FCA origination point sales or when sand is received at the destination for DAP or DAT destination point sales and recorded as accounts receivable. For the Company’s freight revenue, amounts billed depend on the shipping terms and are recorded as receivables accordingly. Generally, billing occurs subsequent to revenue recognition, though certain billing occurs in advance, resulting in unbilled receivables and deferred revenue, respectively. In addition, the Company sometimes receives shortfall payments from or offers pricing concessions to its customers and recognizes the revenue once there are no further obligations to be performed by the Company.

## Deferred Revenues

The Company receives advance payments from certain customers in order to secure and procure a reliable provision and delivery of product. The Company classifies such advances as current or noncurrent liabilities depending upon the anticipated timing of delivery of the supplied product. Deferred revenue is recognized as revenue when performance obligations are met in accordance with the contract.

## Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in accordance with ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, each performance obligation is satisfied. The Company’s contracts may include a single performance obligation in a single contract whereby the allocation of transaction price is not necessary. The Company’s contracts may also contain multiple elements in a single contract or multiple contracts. For contracts with multiple performance obligations, the transaction price is allocated to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognize the related revenue as control of each individual product or service is transferred to the customer, in satisfaction of the corresponding performance obligations. The Company expects to recognize approximately 64% of its remaining performance obligations under existing contracts as revenue in 2021 and expects to recognize the remaining 36% as revenue by 2023.

## Significant Judgments

Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue, costs and satisfaction of performance obligations. The Company satisfies its performance obligation and subsequently recognizes



# SMART SAND, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## (IN THOUSANDS, EXCEPT PER SHARE DATA)

revenue, at a point in time, upon shipment of the products as the customer obtains control over the goods once the sand is loaded into the railcars or sand is delivered to the customer’s destination. In the case of sand being delivered to customers, the transaction price may be variable in nature.

## Cash, Cash Equivalents and Restricted Cash

The Company considers all short-term, highly liquid investments with an original maturity of three months or less to be cash equivalents. The Company had no restricted cash as of December 31, 2020 or 2019. Cash is maintained at financial institutions and, at times, balances may exceed federally insured limits.

## Accounts and Unbilled Receivables

Accounts receivable represents customer transactions that have been invoiced as of the balance sheet date; unbilled receivables represent customer transactions that have not yet been invoiced as of the balance sheet date. Accounts receivable are due in accordance with terms agreed upon with customers, and are stated at amounts due from customers net of any allowance for doubtful accounts. The Company considers accounts outstanding longer than the payment terms past due. The Company determines the allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history, a customer’s current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Accounts receivable are written off when they are deemed uncollectible, and payments subsequently received on such receivables are credited to bad debt expense. As of December 31, 2020 and 2019, the Company recorded no allowance for doubtful accounts. As of December 31, 2020 and 2019, the amount of unbilled receivables included in deferred revenue was $1,443 and $2,282, respectively. As of December 31, 2020 and 2019, respectively, $54,592 and $37,422 of accounts and unbilled receivables were from a customer with which we have pending litigation. See Note 17 - Commitments and Contingencies for additional information.

## Transportation

Transportation costs are classified as cost of goods sold. Transportation costs consist of railway transportation and transload costs to deliver products to customers. Cost of sales generated from shipping was $40,891, $76,643 and $70,532 for the years ended December 31, 2020, 2019 and 2018, respectively.

## Inventories

The Company’s sand inventory consists of raw material (sand that has been excavated but not processed), work-in-progress (sand that has undergone some but not all processing) and finished goods (sand that has been completely processed and is ready for sale). Costs applied to sand inventory include direct excavation costs, processing costs, overhead allocation, depreciation and depletion, transportation and additional service costs, as applicable. Stockpile tonnages are calculated by measuring the number of tons added and removed from the stockpile. Costs are calculated on a per ton basis and are applied to the stockpiles based on the number of tons in the stockpile. The Company performs periodic surveys to verify the quantity of sand inventory on hand. Due to variation in sand density and moisture content and production processes utilized to manufacture the Company’s products, physical inventories will not necessarily detect all variances. To mitigate this risk, the Company recognizes a yield adjustment on its inventories. Sand inventory is stated at the lower of cost or net realizable value using the average cost method.

The spare parts inventory consists of critical spare parts. Spare parts inventory is accounted for on a first-in, first-out basis at the lower of cost or net realizable value.

Certain acquired inventory is stated at fair market value, as determined by its anticipated sales price less costs of disposal and reasonable profit allowance for selling efforts, which may be higher than its cost.

## Deferred Financing Charges

Direct costs incurred in connection with the Company's debt are capitalized amortized using the straight-line method, which approximates the effective interest method, over the term of the debt. Amortization expense of the deferred financing and debt discount charges of $290, $861, and $546 are included in interest expense as of December 31, 2020, 2019 and 2018, respectively. Costs related to the Oakdale Equipment Financing are presented net of the related debt and costs related to the ABL Credit Facility are presented in other assets on the balance sheet.



# SMART SAND, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## (IN THOUSANDS, EXCEPT PER SHARE DATA)

## Financial Instruments

The carrying value of the Company’s financial instruments, consisting of cash, accounts receivable, accounts payable and accrued expenses, approximates their fair value due to the short maturity of such instruments. Financial instruments also consist of debt for which fair value approximates carrying values as the debt bears interest at fixed or variable rates which are reflective of current rates otherwise available to the Company. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments.

## Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Costs related to researching, surveying, drilling, and related activities are recorded at cost and capitalized once a determination has been made that the Company’s property has proven and probable reserves. Capitalized mining costs are depleted using the units-of-production method. Construction in progress is primarily comprised of machinery and equipment which has not been placed in service and is not depreciated until the related assets or improvements are ready to be placed in service. Depreciation is calculated using the straight-line method over the estimated useful lives of the property, plant and equipment, which are:

<table><tr><td></td><td>Years</td></tr><tr><td>Land improvements</td><td>10</td></tr><tr><td>Plant and buildings</td><td>5-15</td></tr><tr><td>Real estate properties</td><td>10-40</td></tr><tr><td>Railroad and sidings</td><td>30</td></tr><tr><td>Vehicles</td><td>3-5</td></tr><tr><td>Machinery, equipment and tooling</td><td>3-15</td></tr><tr><td>SmartSystems</td><td>5-15</td></tr><tr><td>Furniture and fixtures</td><td>3-10</td></tr><tr><td>Deferred mining costs</td><td>3</td></tr></table>

Expenditures for maintenance and repairs are charged against income as incurred; betterments that increase the value or materially extend the life of the related assets are capitalized. Upon sale or disposition of property and equipment, the cost and related accumulated depreciation and amortization are removed from the accounts and any resulting gain or loss is recognized in the consolidated income statements.

## Acquisitions

The Company determines whether a transaction or other event is a business combination, which requires that the assets acquired and liabilities assumed constitute a business. Each business combination is then accounted for by applying the acquisition method. If the assets acquired are not a business, the Company accounts for the transaction or other event as an asset acquisition. Under both methods, the Company recognizes the identifiable assets acquired, the liabilities assumed, contingent considerations and any non-controlling interest in the acquired entity. In addition, for transactions that are business combinations, the Company evaluates the existence of goodwill or a gain from a bargain purchase. The Company capitalizes acquisition-related costs and fees associated with asset acquisitions and expenses acquisition-related costs and fees associated with business combinations in the period in which they are incurred.

## Long-Lived Assets, Including Definite-Lived Intangible Assets

Long-lived assets, other than goodwill and other indefinite-lived intangibles, are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable through the estimated undiscounted future cash flows derived from such assets. Definite-lived intangible assets primarily consist of developed technology and customer relationships. For long-lived assets used in operations, impairment losses are only recorded if the asset’s carrying amount is not recoverable through its undiscounted, probability-weighted future cash flows. The Company measures the impairment loss based on the difference between the carrying amount and the estimated fair value. When an impairment exists, the related assets are written down to fair value.



# SMART SAND, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## (IN THOUSANDS, EXCEPT PER SHARE DATA)

Acquired finite-lived intangible assets are amortized on a straight-line basis over the following periods:

<table><tr><td>Developed technology</td><td>Estimated Useful Life (Years)</td></tr><tr><td></td><td>13</td></tr></table>

In 2020, the Company recorded an impairment loss of $5,115 to fully write down the value of its long-lived assets in the Permian basin as it has no intentions to develop these properties in the foreseeable future. In 2019, the Company recorded impairment losses of $15,542 of which $7,628 related to finite-lived developed technology intangible assets in intangible assets, net on the balance sheet and $7,914 related to its Highton, Wisconsin property in property. plant and equipment, net on the balance sheet. The impairment of the finite-lived intangible assets is from developed technology allocated to the Quickload transloader acquired in connection with the acquisition of Quickthree in 2018. The Company has developed a new transload technology, the Smart Path, and no longer planned to actively market the Quickload and as such, all developed technology intangible assets related to the Quickload were fully impaired during the third quarter of 2019. In the fourth quarter of 2019, the Company determined that the carrying amount of the Highton, Wisconsin property may not be fully recoverable as the Company had no immediate plans to further develop the site. The Company determined the fair value of the Highton, Wisconsin property based on market prices for similar properties sold in the area and recorded an impairment loss for the amount which the carrying value exceeded the fair value.

## Goodwill and Other Indefinite-Lived Intangible Assets

The Company conducts its evaluation of goodwill and other indefinite-lived intangible assets at the reporting unit level on an annual basis as of December 31 and more frequently if events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value. Prior to performing an impairment test, the Company assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment determines that an impairment is more likely than not, the Company performs a quantitative comparison of the fair value with the carrying amount, including goodwill. If this comparison reflects impairment, then the loss would be measured as the excess of recorded goodwill, or other intangible assets with indefinite lives, over its fair value. See Note 6 - Intangible Assets, net for additional information.

In 2018 the Company fully impaired its goodwill and other indefinite-lived intangible assets. During the second half of 2018, the Company saw a decline in demand for frac sand, consistent with the industry as a whole, which resulted in a decline in the Company’s stock price near the measurement date. The decline in the Company’s stock price near the measurement date and the relationship between the resulting market capitalization and the equity recorded on the Company’s balance sheet resulted in a full impairment of goodwill and other indefinite-lived intangible assets in 2018.

## Leases

## Lessee

The Company uses leases primarily to procure certain office space, railcars and heavy equipment as part of its operations. The majority of its lease payments are fixed and determinable with certain of its lease payments containing immaterial variable payments based on the number of hours the equipment is used. Certain of its leases have options that allow for renewal at market rates, purchase at fair market value or termination of the lease. The Company must determine that it is reasonably certain that a lease option will be exercised for such an option to be included in the right-of-use asset or lease liability. The Company is not reasonably certain that any of its lease options will be exercised and, as such, has not included those options in its right-of-use assets or lease liabilities. Certain of its equipment leases contain residual value guarantees which guarantee various parts of heavy equipment will have a remaining life when the equipment is returned to the lessor. It is possible that the Company could owe additional amounts to the lessor upon return of equipment. There are no restrictions or covenants imposed by any of the Company’s leases.

The Company evaluates contracts during the negotiation process and when they are executed to determine the existence of leases. A contract contains a lease when it conveys the right to use property, plant or equipment for a stated period of time in exchange for consideration. Leases with an initial term of twelve months or less are not recorded on the balance sheet. The Company recognizes lease expense on a straight-line basis over the term of the lease. The Company evaluates the classification of its leases at the commencement date and includes both lease and non-lease components in its calculation of consideration in the contract for all classes of operating leases.



# SMART SAND, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## (IN THOUSANDS, EXCEPT PER SHARE DATA)

The Company applies a single discount rate to all operating leases, which is its incremental borrowing rate. The Company determined its incremental borrowing rate based on an average of collateralized borrowing rates offered by various lenders. The Company considered the nature of the assets and the life of the leases and determined that there is no significant difference in the incremental borrowing rate among its classes of assets. See Note 9 — Leases for additional disclosures regarding the Company’s leasing activity.

The Company is obligated under certain contracts for minimum payments for the right to use land for extractive activities, which is not within the scope of leases under ASC 842. See Note 17 — Commitments and Contingencies for additional disclosures regarding these obligations.

## Lessor

The Company manufactures SmartSystems and offers the equipment for lease. The Company negotiates the terms of its leases on a case-by-case basis. There are no significant options that are reasonably certain to be exercised, residual value guarantees, restrictions or covenants in its lease contracts and have, therefore, not been included in its accounting for the leases. All of our SmartSystems are accounted for as operating leases.

## Fair Value Measurements

The Company has categorized its assets and liabilities that are measured at fair value on a recurring and non-recurring basis into a three-level fair value hierarchy, of which the first two are considered observable and the last unobservable, which are as follows:

- Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date;

- Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs corroborated by observable market data for substantially the full term of the assets or liabilities; and

- Level 3—Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing assets or liabilities based on the best information available.

## Contingent Consideration

The Company’s contingent consideration is measured at fair value on a recurring basis and is comprised of payments for production of silos and related equipment during the three-year period after the Quickthree acquisition. Contingent liabilities are valued using significant inputs that are not observable in the market, which are defined as Level 3 inputs according to fair value measurement accounting. As of December 31, 2019 and during 2020, the Company used a probability-weighted average between 1 and 5 manufactured fleets over the remaining earnout period as the basis of its fair value determination. As of December 31, 2020, the Company has no intentions to produce silos or related equipment for the remaining earnout period, and therefore the liability represents the earnout consideration for units produced during 2020.

The fair value of the Company’s financial instruments carried at fair value were as follows:

<table><tr><td rowspan="2"></td><td colspan="2">December 31,</td><td rowspan="2">Level 1</td><td rowspan="2">Level 2</td><td rowspan="2">Level 3</td></tr><tr><td>2020</td><td></td></tr><tr><td>Contingent consideration</td><td>$ 180</td><td>$ —</td><td>$ —</td><td>$ 180</td><td></td></tr><tr><td>Total liabilities</td><td>$ 180</td><td>$ —</td><td>$ —</td><td>$ 180</td><td></td><td></td></tr></table>

## Asset Retirement Obligation

The Company estimates the future cost of dismantling, restoring and reclaiming operating excavation sites and related facilities in accordance with federal, state and local regulatory requirements and recognizes reclamation obligations when disturbance occurs and records them as liabilities at estimated fair value. In addition, a corresponding increase in the carrying amount of the related asset is recorded and depreciated over such asset’s useful life or the estimated number of years of extraction. The reclamation liability is accreted to expense over the estimated productive life of the related asset and is subject to adjustments to reflect changes in value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. Changes in estimates at inactive mines or mining areas are reflected in earnings in the period an estimate is revised. If the asset retirement obligation is settled for more or less than the carrying amount of the liability, a loss or gain will be recognized, respectively.

## Stock-Based Compensation

The Company issues restricted stock to certain employees and members of the board of directors of the Company (the “Board”) for their services on the Board. The Company estimates the grant date fair value of each share of restricted stock at issuance. For awards subject to service-based vesting conditions, the Company recognizes, in the consolidated income statements, stock-based compensation expense equal to the grant date fair value of the award on a straight-line basis over the requisite service period, which is generally the vesting term. For awards subject to both performance and service-based vesting conditions, the Company recognizes stock-based compensation expense on a straight-line basis when it is probable that the performance condition will be achieved. Forfeitures are accounted for when they occur. The Company uses the market price of its shares as the grant date fair value for restricted stock awards.

## Income Taxes

The Company applies the provisions of ASC 740, “Income Taxes” (“ASC 740”), which principally utilizes a balance sheet approach to provide for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of net operating loss carryforwards and temporary differences between the carrying amounts and the tax bases of assets and liabilities.

ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The impact of an uncertain income tax position on the income tax returns must be recognized at the largest amount that is more-likely-than-not to be required to be recognized upon audit by the relevant taxing authority. This standard also provides guidance on derecognition, measurement, classification, interest and penalties, accounting for interim periods, disclosure and transition issues with respect to tax positions. The Company includes interest and penalties as a component of income tax expense in the consolidated income statements. For the periods presented, no interest and penalties were recorded.

## Environmental Matters

The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment. Management has established procedures for the ongoing evaluation of the Company’s operations, to identify potential environmental exposures and to comply with regulatory policies and procedures. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and do not contribute to current or future revenue generation are expensed as incurred. Liabilities are recorded when environmental costs are probable, and the costs can be reasonably estimated. The Company maintains insurance

which may cover, in whole or in part, certain environmental expenditures. As of December 31, 2020 and 2019, there were no material probable environmental matters.

## Segment Information

Reportable operating segments are identified as components of an enterprise about which separate discrete financial information is available and utilized by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company and the Chief Executive Officer view the Company’s operations and manage its business as one reportable operating segment.

## Basic and Diluted Net Income Per Share of Common Stock

Basic net income per share of common stock is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, excluding the dilutive effects of restricted stock. Diluted net income per share of common stock is computed by dividing the net income attributable to common stockholders by the sum of the weighted-average number of shares of common stock outstanding during the period plus the potential dilutive effects of restricted stock outstanding during the period calculated in accordance with the treasury stock method, although these shares and restricted stock are excluded if their effect is anti-dilutive. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share for the years ended December 31, 2020, 2019, 2018 was 1,886, 764 and 854, respectively as their effect would be anti-dilutive. The following table reconciles the weighted-average common shares outstanding used in the calculation of basic net income per share to the weighted average common shares outstanding used in the calculation of diluted net income per share:

<table><tr><td rowspan="2"></td><td colspan="3">Year Ended December 31,</td></tr><tr><td>2020</td><td>2019</td><td>2018</td></tr><tr><td>Weighted average common shares outstanding</td><td>40,260</td><td>40,135</td><td>40,427</td></tr><tr><td>Assumed conversion of restricted stock</td><td>—</td><td>202</td><td>22</td></tr><tr><td>Diluted weighted average common stock outstanding</td><td>40,260</td><td>40,337</td><td>40,449</td></tr></table>

## Reclassification

Certain financial items have been reclassified to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income.

## Recent Accounting Pronouncements

In October 2020, the FASB issued ASU 2020-10, Codification Improvements, which updates various codification topics by clarifying or improving disclosure requirements to align with the SEC’s regulations. The Company will adopt ASU 2020-10 as of the reporting period beginning January 1, 2021. The adoption of this update is not expected to have a material effect on the Company’s consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which intends to simplify the guidance by removing certain exceptions to the general principles and clarifying or amending existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Although the Company is currently evaluating the impact of the adoption of ASU 2019-12, it does not expect it to have a material impact on its consolidated financial statements.

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.

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 will be any applicable allowance recorded against its accounts and unbilled receivables on its balance sheet and related expense on its income statement at that time. 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 — Acquisitions

## 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 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 8 - Debt, for additional information.

The primary assets of Eagle Proppants Holdings and its subsidiaries include two frac sand mines and related processing facilities in Utica, Illinois and New Auburn, Wisconsin, with approximately 3.5 million tons of total combined annual processing capacity, 1.6 million tons of which has access to the BNSF rail line through the Peru, Illinois transload facility.

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

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

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

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

The estimated aggregate fair value of the net assets acquired was $41,680, which exceeds 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.

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 are 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 as these customers are in bankruptcy proceedings. The fair value of inventory was determined using market prices the Company expects to receive for the inventory when it is sold. Operating leases are 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 is 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. During the fourth quarter 2020, the Company finalized the deferred tax liability impacts of the acquisition, resulting in a $289 reduction to the initial gain on bargain purchase. The Company’s allocation of the purchase price is complete as of December 31, 2020.

Total acquisition costs incurred during the year ended December 31, 2020 was $891, which is included in selling, general and administrative expense on the Company’s consolidated income statements.

The following represents pro forma consolidated revenue and income before income tax expense as if Eagle Proppants Holdings had been included in the consolidated results of the Company for the year ended December 31, 2020 and 2019. These amounts have been calculated after applying the Company’s accounting policies and adjusting the results of Eagle Proppants Holdings to reflect the depreciation and accretion expense that would have been charged assuming the fair value adjustments to property, plant and equipment and asset retirement obligations as well as equipment rent that would have been recorded based on the acquired right-of-use assets.

The Company uses the straight-line method to determine the amortization expense for its definite-lived intangible assets. The weighted-average remaining useful life for the intangible assets is 10.4 years. Amortization expense related to the purchased intangible assets was $793, $1,394 and $1,002 for the year ended December 31, 2020, 2019, and 2018, respectively. The Company recorded an impairment charge of $7,628 related to specific developed technology allocated to the Quickload during the third quarter of 2019. Amortizable intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable through the estimated undiscounted future cash flows derived from such assets. The Company has developed and tested a new transload technology and no longer plans to actively market the Quickload and as such, all developed technology intangible assets related to the Quickload has been impaired.

The Company conducted a review of its indefinite-lived intangible assets as of December 31, 2018 and determined the carrying value exceeded its fair value, which resulted in a full impairment of indefinite-lived intangible assets in 2018.

As of December 31, 2020, there were no amounts outstanding under the ABL Credit Facility, $732 letters of credit and $9,459 was available to be drawn. We use this facility primarily as a source for working capital needs. Borrowings under the ABL Credit Facility bear interest at a rate per annum equal to an applicable margin, plus, at our option, either a LIBOR rate or an alternate base rate (“ABR”) as well as unused commitment fees. The applicable margin is 2.00% for LIBOR loans and 1.00% for ABR loans. Substantially all of the U.S. assets of the Company are pledged as collateral under the ABL Credit Facility. The ABL Credit Facility contains various reporting requirements, negative covenants and restrictive provisions and requires maintenance of financial covenants, under certain conditions, including a fixed charge coverage ratio, as defined in the ABL Credit Agreement. As of December 31, 2020, the Company was in compliance with all financial covenants.

## Oakdale Equipment Financing

On December 13, 2019, the Company received net proceeds of $23,000 in an equipment financing arrangement with Nexseer. The Oakdale Equipment Financing is legally comprised of an MLA and five lease schedules. The Oakdale Equipment Financing is considered a lease under article 2A of the Uniform Commercial Code but is considered a financing arrangement for accounting or financial reporting purposes and not a lease. Substantially all of the Company's mining and processing equipment at its Oakdale facility are pledged as collateral under the Oakdale Equipment Financing. The Oakdale Equipment Financing bears interest at a fixed rate of 5.79%. The Company used the net proceeds to repay in full and terminate the Former Credit Facility, pay transaction costs, and the remainder was used for working capital purposes. The Oakdale Equipment Financing matures on December 13, 2024. As a result of financial relief during the COVID-19 coronavirus pandemic in 2020, a portion of the Oakdale Equipment Financing matures on March 31, 2025. The Company has the right to prepay the financing and reacquire the underlying equipment on a lease schedule-by-lease schedule basis during the period commencing on the seventh month of the term and continuing until the 54th month of the term at a percentage of the purchase price of the relevant equipment, and at the end of the term at the fair market value of the equipment. The Oakdale Equipment Financing contains affirmative and restrictive covenants customary for transactions of this type.

## Notes Payable

The Company entered into various financing arrangements to finance its manufactured wellsite proppant storage solutions equipment. Upon completion of the equipment manufacturing, title to the subject equipment passes to the financial institutions as collateral. In June 2020, the Company executed a note payable to defer certain near-term minimum royalty payments. All notes payable bear interest at fixed rates between 4.00% and 7.49%.

## Acquisition Liquidity Support Facility

In connection with the Company’s 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 $5,000 during the twelve month period ending September 18, 2021. Beginning with the calendar quarter ending December 31, 2021, any amounts borrowed will amortize over the following three years. The facility bears interest at a fixed rate of 6.00% until September 18, 2021 and will bear interest at a fixed rate of 8.00%

## NOTE 12 — Earnings Per Share

Basic net income per share of common stock is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, excluding the dilutive effects of restricted stock. Diluted net income per share of common stock is computed by dividing the net income attributable to common stockholders by the sum of the weighted-average number of shares of common stock outstanding during the period plus the potential dilutive effects of 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. The number of shares underlying equity-based awards that were excluded from the calculation of diluted earnings per share for the years ended December 31, 2020, 2019, and 2018 was 1,886, 764, and 854, respectively as their effect would be anti-dilutive. The following table reconciles the weighted-average common shares outstanding used in the calculation of basic net income per share to the weighted average common shares outstanding used in the calculation of diluted net income per share:

## NOTE 13 — 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. The awards can be issued in the form of incentive stock options, non-qualified stock options or restricted stock.

During 2020, there were no shares of restricted stock issued under 2016 Plan. During 2019 and 2018, 1,884 and 746 shares of restricted stock were issued under the 2016 Plan, respectively. The grant date fair value of all the restricted stock per share was $2.44 - $19.00. The shares vest over one to five years from their respective grant dates. For Awards issued under the 2016 Plan, the grant date fair value was the either the actual market price of the Company’s shares or an adjusted price using a Monte Carlo simulation for awards subject to the Company’s performance as compared to a defined peer group. The significant assumptions used in the Monte Carlo simulation are presented in the following table.

<table><tr><td rowspan="2"></td><td colspan="2">Year ended December 31,</td></tr><tr><td>2019</td><td></td></tr><tr><td>Expected volatility</td><td>71.05 %</td><td></td></tr><tr><td>Expected life (years)</td><td>2.0</td><td></td></tr><tr><td>Risk-free interest rate</td><td>1.63 %</td><td></td></tr></table>

The total number of shares and their respective fair values that vested during the years ended December 31, 2020, 2019 and 2018 were 675 at $1,013, 261 at $844 and 177 at $1,047, respectively.

The Company recognized $3,831, $2,909 and $2,937 of compensation expense for the restricted stock during 2020, 2019 and 2018, respectively, in cost of goods sold and operating expenses on the consolidated income statements. There is no impact to the cash flows of the Company related to stock-based compensation expense. At December 31, 2020, the Company had unrecognized compensation expense of $3,691 related to granted but unvested stock awards. That expense is expected to be recognized as follows:

## NOTE 14 — Income Taxes

On March 27, 2020, the President signed into law the Coronavirus Aid, Relief and Economic Security (“CARES”) Act which introduced and revised numerous provisions which include, but are not limited to, (a) a five-year carryback period for net operating losses arising in tax years beginning tax after December 31, 2017 and before January 1, 2021, (b) a technical correction to qualified improvement property for assets placed in service after 2017 through 2022 to allow for immediate depreciation to be claimed on these assets, and (c) temporary increases to the limitations on certain deductions such as interest expense and charitable contributions.

As a result of the CARES Act, the Company recorded a current tax benefit of $9.7 million related to the anticipated benefit to be received from the carryback of net operating losses, including those related to depletion deduction, to tax years with a 35% corporate tax rate. The Company will continue to monitor and consider available benefits under the CARES Act for which it qualifies, including those described above.

On December 27, 2020, the President signed into law the Consolidated Appropriations Act, 2021 (the “CAA”). The legislation includes additional coronavirus (COVID-19) relief that expands upon the relief provided in the CARES Act and a number of tax provisions. Tax provisions under the CAA include, but are not limited to, (a) the extension for employers to pay certain deferred payroll taxes and (b) the extension and revision of employer retention credits. Although the Company is currently evaluating the impact of CAA, it does not expect it to have a material impact on its consolidated financial statements for the year ended December 31, 2020.

Income tax expense differs from the amounts computed by applying the statutory income tax rates to pretax income. The statutory income tax rates were 21% for the years ended December 31, 2020, 2019 and 2018. The reconciliations from the applicable statutory income tax rates to income tax (benefit) expense are as follows:

In assessing the realizability of deferred tax assets, the Company considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which those temporary differences become deductible. At December 31, 2020 and 2019, based on the Company’s future income projections and reversal of taxable temporary differences, management determined it was more likely than not that the Company will be able to realize the benefits of the deductible temporary differences. As of December 31, 2020 and 2019, the Company determined no valuation allowance was necessary.

The Company has evaluated its tax positions taken as of December 31, 2020 and 2019 and believes all positions taken would be upheld under examination from income taxing authorities. Therefore, no liability for the effects of uncertain tax positions has been recorded in the accompanying consolidated balance sheets as of December 31, 2020 or 2019. The Company is open to examination by taxing authorities beginning with the 2015 tax year.

## ITEM 9A. — CONTROLS AND PROCEDURES

## Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were effective.

## Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not detect or prevent misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As of December 31, 2020, our management assessed the effectiveness of our internal control over financial reporting based on the criteria for effective internal control over financial reporting established in Internal Control - Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on its assessment, management determined that we maintained effective internal control over financial reporting as of December 31, 2020.

Our independent registered public accounting firm is not yet required to formally attest to the effectiveness of our internal controls over financial reporting, and will not be required to do so for as long as we are an “emerging growth company” pursuant to the provisions of the JOBS Act.

## Changes in Internal Controls Over Financial Reporting

There have been no changes in our internal control over financial reporting for the three months ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
