As used herein, “Company”, “we”, “our” and “us” may refer to CARBO Ceramics Inc. (“CARBO”) and/or its consolidated subsidiaries.

Recent Developments

Voluntary Reorganization Under Chapter 11 of the Bankruptcy Code

On March 29, 2020 (the “Petition Date”), CARBO and its direct wholly owned subsidiaries Asset Guard Products Inc. (“AGPI”) and StrataGen, Inc. (“StrataGen,” and together with CARBO and AGPI, the “Debtors”) filed voluntary petitions (the “Bankruptcy Petitions”) for reorganization under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”). The Chapter 11 proceedings are being jointly administered under the caption In re CARBO Ceramics Inc, et al. (the “Chapter 11 Cases”).

On March 28, 2020, the Debtors entered into a restructuring support agreement (the “RSA”) with the holders of all of the loans outstanding under the Amended and Restated Credit Agreement, dated as of March 2, 2017 (as amended, the “Credit Agreement”), by and among CARBO, as borrower, AGPI and StrataGen, as guarantors, Wilks Brothers, LLC, as administrative agent and lender (“Wilks”), Equify Financial, LLC (“Equify”), as lender (together with Wilks, the “Supporting Lenders”) that sets forth the terms of a prenegotiated Chapter 11 plan of reorganization (the “Plan”) pursuant to which, among other things and subject to the terms and conditions of the RSA, each Supporting Lender will receive its pro rata share of 100% of the equity interests in a reorganized CARBO entity (“Reorganized CARBO” and such interests, the “Reorganized CARBO Interests”) in exchange for its secured claims under the Credit Facility and its claims under the DIP Facility described below, except to the extent such DIP Facility claims (the “DIP Facility Claims”) are converted into borrowings under an exit credit facility, with Reorganized CARBO retaining (i) 100% of the equity interests in a reorganized AGPI entity and (ii) 100% of the equity interests in a reorganized StrataGen entity. In addition, pursuant to the Plan, a liquidating trust (the “Liquidating Trust”) will be established for the benefit of general unsecured creditors. The Supporting Lenders will contribute $100,000 to fund the costs of administering the Liquidating Trust, and any avoidance actions that are not otherwise released under the Plan will be transferred to the Liquidating Trust. The Chapter 11 Cases and the restructuring transactions contemplated by the RSA and the Plan (collectively, the “Restructuring”) are expected to result in the cancellation of CARBO’s common stock. The Debtors filed the Plan with the Bankruptcy Court on April 8, 2020.

The Bankruptcy Petitions constituted an event of default that accelerated the Debtors’ obligations under the Credit Agreement. However, under the Bankruptcy Code, the Supporting Lenders are stayed from taking any action against the Debtors as a result of this event of default.

Debtor-in-Possession Financing

On March 30, 2020, the Debtors entered into the DIP Credit Agreement with the DIP Facility Lenders providing for a $15 million DIP Facility. On March 30, 2020, the Bankruptcy Court granted interim approval of the Debtors’ motion to approve the DIP Facility, including the DIP Credit Agreement, and the borrowing by CARBO of up to $5 million of loans thereunder between March 30, 2020 and the Bankruptcy Court’s entry of a final order approving the DIP Facility and DIP Credit Agreement.

The Debtors’ obligations under the DIP Credit Agreement are secured by first priority priming liens on substantially all of the Debtors’ assets, subject to certain customary exclusions and carve-outs. Borrowings under the DIP Facility will mature August 29, 2020 (the “Maturity Date”) and will bear interest at a rate of 8.00% per annum. For more information regarding the DIP Credit Agreement and DIP Facility, see “Part I―Business―Recent Developments―Debtor-in-Possession Financing”. The DIP Credit Agreement also provides for the payment of certain fees, including an unused commitment fee and upfront fee, as well as a DIP fee to be paid to the DIP Facility Lenders in the event the Debtors enter into an alternative debtor-in-possession financing arrangement with financial institutions other than the DIP Facility Lenders in lieu of the DIP Facility. Interest and any other amounts that become due under the DIP Facility will be paid in cash. The proceeds of the DIP Facility, including the Interim Period Borrowings, will be used to pay fees, expenses and other expenditures of the Debtors to be set forth in rolling budgets prepared in connection with the Chapter 11 Cases, subject to the approval of the DIP Facility Lenders and certain stipulated exceptions.

The DIP Credit Agreement terminates on the earliest of: (a) the Maturity Date; (b) the effective date of any Acceptable Plan or any other Chapter 11 Plan (each as defined in the DIP Credit Agreement); (c) the entry of an order for the conversion of any of the Chapter 11 Cases to a case under Chapter 7 of the Bankruptcy Code; (d) the entry of an order for the dismissal of any of the Chapter 11 Cases; and (e) at the election of the DIP Facility Lenders, the date on which any event of default under the DIP Credit Agreement is continuing.

The DIP Credit Agreement contains usual and customary affirmative and negative covenants and events of default for transactions of this type. In addition, the Debtors are required to maintain a minimum liquidity of $2,500,000 as of the last day of any calendar month following the effective date. On March 29, 2020, in connection with the filing of the Chapter 11 Cases, the Debtors entered into a commitment letter with Wilks (the “Commitment Letter”).

On April 8, 2020, the Debtors filed the Plan and a Disclosure Statement for the Debtors’ Joint Chapter 11 Plan of Reorganization (the “Disclosure Statement”).

Additional information about the Chapter 11 Cases, including the Plan, the Disclosure Statement and motions, orders and other court filings relating thereto, may be obtained by visiting http://dm.epiq11.com/Carbo or by calling 1-866-897-6433 (Toll Free) or 1-646-282-2500 (International). The above-mentioned motions and procedures are also available on the docket of the Chapter 11 Cases, which can be accessed via PACER at https://www.pacer.gov.

Going Concern and Financial Reporting in Reorganization

As a result of our financial condition, the defaults under our Credit Agreement and the risk and uncertainties surrounding the Chapter 11 Cases, substantial doubt exists regarding our ability to continue as a going concern. Accordingly, the audit report issued by our independent registered public accounting firm on our financial statements as of and for the year ended December 31, 2019 contains an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which contemplate our continuation as a going concern. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern. For additional information concerning our bankruptcy proceedings under Chapter 11, see Note 1 to the Consolidated Financial Statements.

Listing and Trading of our Common Stock

Our common stock traded on the New York Stock Exchange (the “NYSE”) under the symbol “CRR” until December 20, 2019, at which time trading in our common stock on the NYSE was suspended due to our inability to satisfy the continued listing requirements of the NYSE. Trades in our common stock began being quoted on the OTCQB Market on December 23, 2019 under the symbol “CRRT”. As a result of the filing of the Chapter 11 Cases, our stock was removed from the OTCQB Market on March 31, 2020 and is currently quoted on the OTC Pink marketplace under the trading symbol “CRRTQ”.

General

~~CARBO~~The ~~Ceramics Inc. (“we,” “us,” “our” or our “~~Company”) is a global technology company that provides products and services to the oil and gas, industrial, and environmental markets to enhance value for its clients. The Company was incorporated in 1987 in Delaware. ~~As used herein, “Company”, “CARBO”, “we”, “our” and “us” may refer to the Company and/or its consolidated subsidiaries.~~

The Company conducts its business within two operating segments: 1) Oilfield and Industrial Technologies and Services and 2) Environmental Technologies and Services. Financial information about reportable operating segments is provided in Note 1413 to the Company’s Consolidated Financial Statements.

The Company’s Oilfield and Industrial Technologies and Services segment manufactures and sells ceramic technology products and services, and base ceramic proppant ~~and frac sand~~ for both the oilfield and industrial sectors. The products have different technology features and product characteristics, which vary based on the application for which they are intended to be used. The various ceramic products’ manufacturing processes are similar.

Oilfield ceramic technology products, and base ceramic proppant ~~and frac sand proppant~~ are manufactured and sold to pressure pumping companies and oil and gas operators for use in the hydraulic fracturing of natural gas and oil wells. Hydraulic fracturing is the most widely used method of increasing production from oil and natural gas wells. The hydraulic fracturing process consists of pumping fluids down a natural gas or oil well at pressures sufficient to create fractures in the hydrocarbon-bearing rock formation. A granular material, called proppant, is suspended and transported in the fluid and fills the fracture, “propping” it open once high-pressure pumping stops. The ~~proppant filled fracture creates a conductive channel through which the hydrocarbons can flow more freely from the formation to the well and then to the surface.~~

There are three primary types of proppant that can be utilized in the hydraulic fracturing process: sand, resin coated sand and ceramic. Sand is the least expensive proppant, resin-coated sand is more expensive and ceramic proppant is typically the most expensive. We believe that the higher initial cost of ceramic proppant is justified by the fact that its use in certain well conditions typically results in an increase in the production rate of oil and natural gas, an increase in the total oil or natural gas that can be recovered from the well and, consequently, an increase in cash flow for the operators of the well. The increased production rates are primarily attributable to the higher strength and more uniform size and shape of ceramic proppant versus alternative materials. We are one of the world’s largest suppliers of ceramic proppant.2

The increased production rates are primarily attributable to the higher strength and more uniform size and shape of ceramic proppant versus alternative materials. During the fourth quarter of 2019, we idled all of our sand operations, and we do not expect to resume operations.

We manufacture various distinct ceramic proppants. Our technology suite of ceramic proppants includes the following:

KRYPTOSPHERE^® HD is a high-performance mono-mesh ceramic proppant engineered to deliver increased conductivity and durability in the highest closure stress wells. In challenging, high-cost environments such as ultra-deep wells, KRYPTOSPHERE HD retains its integrity and enables greater production and Estimated Ultimate Recovery (“EUR”) from the reservoir.

KRYPTOSPHERE XT meets client needs for a lower density proppant than KRYPTOSPHERE HD, and the closure stress is lower than the application for KRYPTOSPHERE HD, but higher than KRYPTOSPHERE LD. Commercialization occurred in January 2019.

KRYPTOSPHERE LD meets client needs for a lower density proppant than KRYPTOSPHERE HD, yet has similar characteristics and conductivity in high stress wells.

SCALEGUARD^® is a porous ceramic proppant that is infused with scale-inhibiting chemicals and placed throughout the fracture as part of the hydraulic fracturing process. The infused scale inhibitor in SCALEGUARD is designed to be released into the fracture only on contact with water and thereby reduce or eliminate expensive remedial maintenance programs. SALTGUARD^® was commercialized in 2018. The product has been shown to prevent salt build up in oil and gas wells.

Our FUSION^® technology improves well productivity by forming a stable, high-permeability proppant pack that prevents proppant washout from the non-compressive annulus and near-wellbore areas.

1CARBOAIR® is a high-transport, ultra-low-density ceramic proppant technology that has been developed primarily to increase production and EUR from slickwater fracturing operations. The technology enables exploration and production (“E&P”) operators to avoid the introduction of gel into their fracs while increasing reservoir contact and improving fracture conductivity.

CARBOAIR® is a high-transport, ultra-low-density ceramic proppant technology that has been developed primarily to increase production and EUR from slickwater fracturing operations. The technology enables exploration and production (“E&P”) operators to avoid the introduction of gel into their fracs while improving reservoir contact and fracture conductivity.

NANOMITE™ C is a micro mesh ceramic proppant which is engineered to prop natural fractures which are opened during the hydraulic fracturing process which would not normally be propped open. The resulting propped reservoir contact increases and the EUR is increased.

Our RPM relative permeability modification technology is engineered to alter the wettability of proppant to neutral, preventing the retention of water-based fluid in the proppant pack. As a result, RPM technology increases the effective fracture length, conductivity and permeability of the pack to hydrocarbons, leading to higher production and increased ultimate recovery.

In addition, we manufacture CARBONRT^®, a detectable proppant that utilizes a non-radioactive tracer material to assist operators in determining the locations of fractures in a natural gas or oil well. This tracer is added to the proppant granules during the manufacturing process, and can be added to most of the types of proppant that the Company sells.

Our base ceramic suite of products ~~include~~includes:

CARBOLITE^® and CARBOECONOPROP^® are low-density ceramic proppants. CARBOLITE^® is used in medium depth oil and natural gas wells, where higher production rates can be achieved due to the product’s uniform size and spherical shape. CARBOECONOPROP was introduced to provide a lower cost ceramic to compete more directly with resin-coated sand and sand proppant.

We produce resin-coated ceramic (CARBOBOND LITE^®), which addresses a niche market in which oil and natural gas wells are subject to the risk of proppant flow-back.

Our sand proppants include CARBO NORTHERN-WHITE, which is a frac sand that is used by operators that still value quality, but do not wish to pay the higher costs associated with ceramic or resin-coated proppants.3

Our industrial ceramic technology products are manufactured and sold to industrial companies globally. These products are designed for use in various industrial technology applications, including but not limited to casting and milling.

Our industrial sand products are manufactured and sold to industrial companies. These products are designed for use in various industrial applications.

ACCUCAST^® is a high-performance ceramic casting media that is engineered for precision performance. Outperforming specialty and silica sand products, their unique thermal, physical and chemical properties reduce media consumption and costs, lower production defects and reduce energy consumption.

CARBOGRIND^® is a high-performance ceramic media that improves grinding efficiency while lowering operational costs for clients. The durability of our ceramic grinding media results in longer product life, while the uniform size and spherical shape add efficiency to grinding operations and reduce wear on the mechanical parts of milling equipment.

The CARBOBEAD™ family of high-performance ceramic media technologies are engineered to provide economic, Health, Safety and Environmental (HSE) and performance advantages in a wide variety of industrial applications compared to sand and other competing synthetic media types.

We also produce industrial products at our manufacturing facilities for third parties under tolling arrangements. These products have been used in industrial, agricultural and oilfield applications. ~~Contract manufacturing has led to increased revenue generation.~~ We continue to ~~develop~~work towards developing additional opportunities within the industrial, agricultural and oil and gas industries to grow revenue, and to reduce our plant’s slowing and idling costs.

Through our wholly-owned subsidiary StrataGen, Inc., we promote increased production and EUR of oil and natural gas by selling a widely used fracture stimulation software under the brand FracPro^®, and providing fracture design and consulting services to oil and natural gas E&P companies under the brand StrataGen^®.

FracPro provides a suite of stimulation software solutions used for designing fracture treatments and for on-site real-time analysis. Use of FracPro enables our clients to optimize stimulation jobs to enhance oil and gas production. FracPro has been integrated with third-party reservoir simulation software, furthering its reach and utility.

The StrataGen consulting team works with operators around the world to help optimize well placement, fracture treatment design and production enhancement. The broad range of expertise of the StrataGen consultants includes: fracture treatment design; completion support; on-site treatment supervision; quality control; post-treatment evaluation and optimization; reservoir and fracture studies; rock mechanics and software application and training.

Our Environmental Technologies and Services segment is intended to protect operators’ assets, minimize environmental risks and lower lease operating expense (“LOE”). Asset Guard Products Inc. (“AGPI”), the only wholly-owned subsidiary of ours to operate in this segment, provides spill prevention, containment and countermeasure systems for the oil and gas and industrial industries. AGPI uses proprietary technology to make products designed to enable its clients to extend the life of their storage assets, reduce the potential for hydrocarbon spills and provide containment of stored materials.

Current demand for proppant is extremely dynamic. Most of our oilfield products and services depend primarily on the supply of and demand for oil and natural gas, as well as on the number of natural gas and oil wells drilled, completed or re-completed worldwide. More specifically, the demand for most of our products and services is dependent on the number of oil and natural gas wells that are hydraulically fractured to stimulate production. The demand for our products and services is also dependent on the commodity price of oil and natural gas, and lower commodity prices result in fewer purchases of our premium products. In addition, our results of operations are also significantly affected by a host of other factors, including but not limited to (a) rig counts, (b) well completions activity, which is not necessarily correlated with rig count, (c) customer preferences, (d) new product and technology adoption, (e) imports and competition, (f) changes in the product mix of what we sell, (g) costs of developing our products and services and running our business, and (h) changes in our strategy and execution.

During the year ended December 31, ~~2018~~2019, we generated approximately 8173% of our consolidated revenues in the United States and 1927% in international markets.

Competition

As the demand for ceramic proppant (including proppant produced by us) continued to be negatively impacted in ~~2018~~2019 ~~by the severe decline in the oil~~ and ~~natural~~continuing ~~gas~~into ~~industry~~2020, the number of domestic and international competitors in the marketplace continued to decrease, and many of our competitors have shut down plants and/or reduced production. However, we do not have full visibility as to the extent or duration of these shut-downs and reductions. One of our worldwide proppant competitors is Saint-Gobain Proppants (“Saint-Gobain”). Saint-Gobain is a division of Compagnie de Saint-Gobain, a large French glass and materials company. Saint-Gobain manufactures a variety of ceramic proppants that it markets in competition with some of our products. Saint-Gobain’s primary manufacturing facilities are located in Bauxite, Arkansas. Saint-Gobain also manufactures ceramic proppant in China. Mineracao Curimbaba (“Curimbaba”), based in Brazil, also manufactures and markets ceramic proppant in competition with some of our products. Imerys, S.A., a competitor based in France (“Imerys”), has ceramic proppant manufacturing facilities in Andersonville and Wrens, Georgia and also competes with some of our products.

We are aware of a number of manufacturers in China. Most of these companies produce intermediate-density and low-density ceramic proppants that are marketed both inside and outside of China. Chinese proppant imports into the United States increased beginning in 2010 and 2011, which contributed to an over-supply of ceramic proppant beginning in 2012. However, beginning in early 2015, imports declined significantly or stopped.4

Saint-Gobain also manufactures ceramic proppant in China. Mineracao Curimbaba (“Curimbaba”), based in Brazil, also manufactures and markets ceramic proppant in competition with some of our products. Imerys, S.A., a competitor based in France (“Imerys”), has ceramic proppant manufacturing facilities in Andersonville and Wrens, Georgia and also competes with some of our products. Imerys sold their Wrens, Georgia proppant manufacturing facility to a third party in 2019.

Our KRYPTOSPHERE product line replaced both CARBOHSP and CARBOPROP. Historically, competition for CARBOHSP and CARBOPROP principally includes ceramic proppant manufactured by Saint-Gobain, Curimbaba, as well as various manufacturers located in China. Our CARBOLITE, CARBOECONOPROP and CARBOHYDROPROP products compete primarily with ceramic proppant produced by Saint-Gobain, Curimbaba and Imerys and with sand-based proppant for use in the hydraulic fracturing of natural gas and oil wells. At this time, there is not in our view a comparable competitor’s product to our mono-mesh KRYPTOSPHERE product line, which is the subject of patent protection.

We believe that some of the significant factors that influence a customer’s decision to purchase our ceramic proppant are (i) reservoir and geological characteristics, (ii) price/performance ratio, (iii) on-time delivery performance, (iv) technical support, (v) proppant availability and (vi) the financial status of E&P operators. We believe that our products are competitively priced and that our delivery performance and customer experience is far better than the competition. We have seen an increased usage of our technology proppants internationally and in North America, especially with E&Ps which are focused on increasing the EUR of their wells, are completing wells with higher permeability or are making attempts to lower their lease operating expenses (LOE).

3The leading suppliers of Northern White mined sand are Covia Corporation, U.S. Silica Company, Hi-Crush Partners LP, and Badger Mining Corp. There are several other sand competitors (including the aforementioned) which have added in-basin capacity in the last year.

The leading suppliers of Northern White mined sand are Covia Corporation, U.S. Silica Company, Hi-Crush Partners LP, and Badger Mining Corp. There are several other sand competitors (including the aforementioned) which have added in-basin capacity in the last year. This is sand which has significantly lower quality (resulting in lower EUR and production), but is closer to where the wells will be completed resulting in significantly lower costs. A large majority of our sand from our Northern White sand plant as well as the distribution center it is being railed into is under contract.

Our industrial ceramic products enhance our clients’ performance for their manufacturing processes, products, and services. The two primary industries of the ten market segments we currently serve are foundry with our ACCUCAST products and grinding applications with our CARBOGRIND products. Our industrial sector has competitors across several industries we sell into.

ACCUCAST metal casting media products are used by foundries to form high quality cores and molds. During the past year, our sales activity has focused on North America and primarily in the United States due to the new OSHA PEL for respirable crystalline silica that went into effect in 2018 for foundries. ACCUCAST ceramic media is a solution for the new OSHA requirements. We utilize direct sales B2B and a network of qualified distributors. Our competition in the North American foundry market includes several ceramic media manufacturers and the primary competitors in the North American foundry market is Itochu and Prince Minerals. Itochu, based in Tokyo and Osaka, Japan, is a diverse global company competing in many industries including Textile, Machinery, Metals & Minerals, Energy & Chemicals, Food, General Products & Realty, and Financial Business Services with distribution facilities and manufacturing located globally. Their Cerabeads, casting media for the foundry market, is produced in Japan and distributed globally. Sales are direct B2B and through a broad group of distributors. Prince Minerals, headquarters in Houston, TX, is a manufacturer and distributor of specialty chemicals and industrial additives. They sell direct B2B and through distributors selling both internally and externally manufactured products. Their Ceramcast, media for the foundry market, has been historically produced by a third -party manufacturer in China with narrow product offerings for foundries.

CARBOGRIND products are used in milling equipment for processing ore in the precious metals mining industry and other milling applications such as pigments, paints, and ceramic tile. Within the precious metals mining industry, we sell globally through direct sales teams and distributors. Competitors in the precious metals mining industry include Keramos, Magotteaux, Saint Gobain, Kings, and Cenotec. The majority of these competitors manufacture their ceramic grinding products in manufacturing plants located in China.

We believe some of the significant factors that influence a customer’s decision to purchase our industrial ceramic media are (i) broad portfolio of superior ceramic products designed specifically to solve challenges for different industries (ii) excellent price/performance ratio, (iii) on-time delivery performance, (iv) technical support, (v) product availability (vi) consistent superior quality and (vii) the financial status of our clients. We believe our industrial products are competitively priced and our delivery performance and customer experience is better than the competition. Lastly, our superior technical support has enabled us to persuade ~~customers to use our products in an increasingly broad range of applications which in turn has increased the overall market for our industrial products.~~

The ASSETGUARD™ environmental sector is divided into two divisions: a manufacturing division and a services division. The manufacturing division supplies products into both the oil and gas and industrial markets. The service business, operating as Falcon Technologies, provides services to the oil and gas market. In 2018, oil and gas activity levels accelerated beyond those seen in both 2016 as well as 2017, and as a result additional competition entered into the market. Falcon Technologies operates in the United States, and we are aware of at least two dozen competitors operating within the United States.5

In 2018, oil and gas activity levels accelerated, and as a result additional competition entered into the market at that time. Falcon Technologies operates in the United States, and we are aware of at least two dozen competitors operating within the United States.

It is our belief that there are several key factors that are driving customers to purchase from ASSETGUARD, including (i) centralized manufacturing, which offers customers one stop shopping capability, along with a proven track record of on time delivery and competitive pricing, (ii) field services that are established across the United States as being professional, efficient, and reliable and centered on customer satisfaction, (iii) and the technical support available to the customer is unmatched in the industry, ensuring that the client receives timely response to their issues and quick resolution to any problem that might arise.

Product Development

We have broadened our product development efforts in 2018 to address the dynamic growth of the industrial, contract manufacturing, and environmental sectors. Product development efforts are roughly equally split between oilfield and industrial applications.

SALTGUARD was commercialized in our GUARD® product line to prevent salt buildup in oil and gas wells.

CARBOGRIND, our superior line of grinding media, portfolio of products continues to grow. Many new product offerings were launched in 2018 as a direct result of our customers requiring grinding solutions to solve their grinding challenges. The portfolio of

products will continue to grow as our development team develops products with heavier densities, various sizes, and improve grinding performance.

QUANTUM™ service based on iON™ electrically conducting proppant continues to be the industry best method to directly measure hydraulic fracture dimensions. This technology will become commercial in 2019.

Intellectual property continues to be a strong focus to support our technology leadership. In 2018, ten patents were issued to the Company.

Customers and Marketing

The customer base within CARBO is transforming as our revenue streams change from primarily oil and gas, to oil and gas, industrial and environmental customers. The three business sectors are each utilizing different sales channels, including direct to the end consumer of our products and services, an intermediary which adds their services around our products, distributors and through ecommerce for certain products. We are seeing shifts in the purchasing behaviors of some of the end users of our products and have changed and are changing our sales and marketing efforts accordingly.

We generally supply our customers with products on a just-in-time basis, as specified in individual purchase orders. Continuing sales of product depend on our direct customers and the operators being satisfied with value creation, product quality, availability and delivery performance. In addition, our ability to increase sales of our products and services depends on a favorable level of activity in the upstream oil and gas industry and expansion into other industrial and environmental business segments as well as capturing further market share in conventional segments.

We recognize the importance of a technical marketing program in demonstrating long-term economic advantages when selling products and services that offer financial benefits over time. WeOur ~~have a broad technical~~ sales force seeks to advise end users on the benefits of using our base ceramic proppant, technology ceramic products, fracture simulation software, and related consulting services. In addition we have added domain technical expertise within our industrial business unit to provide technical recommendations and ongoing support throughout the sales and ownership process. We also believe that our new product introductions and education-based technical marketing efforts have enabled us to maintain our position not only as one of the world’s largest suppliers of ceramic proppant but also as a leading innovator in the three sectors we sell into: oil and gas, industrial and environmental.

Production Capacity

We have adequate capacity to support present and foreseeable demand for our products. ~~We continue to incorporate new methods and technologies to reduce our manufacturing costs and make our products more cost-competitive.~~ Our manufacturing costs per unit are typically inversely related to production levels. When production levels increase, costs per unit tend to decrease, and when production levels decrease, costs per unit tend to increase.

Stated capacity of our facilities varies based on the mix of products we expect to produce. The following table sets forth the current stated capacity of each of our existing ceramic manufacturing and other facilities:

	Annual
Location	Capacity
	(millions of pounds)
Eufaula, Alabama		245	*
McIntyre, Georgia		275	*
Toomsboro, Georgia		1,000	***
Total ceramic manufacturing capacity		1,520
Marshfield, Wisconsin – sand processing		1,500	***
New Iberia, Louisiana – resin-coating		330	**
Total current capacity		3,350

*	Given market conditions, output levels at these facilities are at reduced levels.

**	Processing activities at the New Iberia facility primarily involve resin-coating of previously manufactured ceramic proppant substrate.

~~The~~*** ~~retrofit~~Beginning ofin the ~~first~~fourth ~~production~~quarter ~~line at our Eufaula, Alabama plant to produce KRYPTOSPHERE was completed in late 2015. With this retrofit, we can now produce up to approximately 100 million pounds~~ of ~~KRYPTOSPHERE annually.

During the fourth quarter of 2019, the Company began to shift predominantly all industrial ceramic media production to its McIntyre, Georgia facility and all oilfield ceramic proppant production to its Eufaula, Alabama facility. The Toomsboro, Georgia plant was idled, and at this time, we do not intend to resume operations. Our resin-coating line at New Iberia, Louisiana is expected to continue to resin coat and infuse ceramic proppant primarily for our oilfield customers. In April 2020 and as a result of the current market conditions, the Company provided a WARN Act notice under the Worker Adjustment and Retraining Notification Act due to the Company’s likely closure of the Eufaula, Alabama plant in June 2020. The current expectation is for the Company to operate our McIntyre, Georgia and New Iberia, Louisiana plants, both for the oilfield and industrial markets. However, as a result of our bankruptcy filing, the production and utilization plan for our plants may significantly change as a result of the outcome of the bankruptcy.

During 2019, our overall total ceramic plant utilization was approximately 12% of stated capacity. Our sand processing plant in Marshfield operated at approximately 63% of its stated capacity during 2019. During the fourth quarter of 2019, we idled our sand processing facility in Marshfield, Wisconsin and our ceramic manufacturing facility in Toomsboro, Georgia. Refer to our discussion of impairment considerations in the “Critical Accounting Policies” section of Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations. Construction of additional manufacturing capacity beyond our existing facilities is not expected in the foreseeable future.

Distribution

We maintain finished goods inventories at each of our manufacturing facilities and at remote stocking facilities. Our North American remote stocking facilities consist of bulk storage silos with truck trailer and sand box loading facilities, as well as rail yards for direct transloading from rail cars to truck trailers. We lease one of our distribution centers to a third party. International remote stocking sites are duty-free warehouses operated by independent owners. North American sites are typically supplied by rail, and international sites are typically supplied by container ship. In total, we lease approximately 1,~~691~~334 rail cars for use in the distribution of our products, of which we have subleased approximately ~~570~~45 rail cars. The majority of our fleet of rail cars are not expected to be used in the future, and as a result of changes to our long-term forecast and business model, we currently only expect to use a very limited number of railcars in our business. We recorded an impairment of right of use assets related to excess rail cars during the fourth quarter of 2019.

Raw Materials

Ceramic proppant and ceramic media are made from alumina-bearing ores (commonly referred to as clay, bauxite, bauxitic clay or kaolin, depending on the alumina content) that are readily available on the world market. The main known deposits of alumina-bearing ores in the United States are in Arkansas, Alabama and Georgia; other economically mineable known deposits are located in Australia, Brazil, China, Gabon, Guyana, India, Jamaica, Russia and Surinam. Bauxite is largely used in the production of aluminum metal, refractory material and abrasives. We believe that our ability to purchase bauxite on the open market coupled with our current bauxite inventories will sufficiently provide for our bauxite needs in the United States during 2019.

Our Eufaula, McIntyre and Toomsboro facilities primarily use locally mined kaolin for the production of CARBOLITE, CARBOECONOPROP and CARBOHYDROPROP. We have entered into bi-lateral contracts that require a supplier to sell to us, and require us to purchase from the supplier, at least fifty percent of the Eufaula facility’s annual kaolin requirements. The contract runs through May 2020, with an option for us to extend this agreement for additional three year terms. We have obtained ownership rights in acreage in Wilkinson County, Georgia, which contains in excess of a twelve year supply of kaolin for our Georgia facilities based on full capacity production rates. We have entered into a long-term agreement with a third party to mine and transport this material at a fixed price subject to annual adjustment. The agreement requires us to utilize the third party to mine and transport a majority of the McIntyre and Toomsboro facility’s annual kaolin requirement. Overall, we estimate that our fee simple and leasehold mineral rights 7

We have entered into a long-term agreement with a third party to mine and transport this material at a fixed price subject to annual adjustment. The agreement requires us to utilize the third party to mine and transport a majority of the McIntyre and Toomsboro facility’s annual kaolin requirement. Overall, we estimate that our fee simple and leasehold mineral rights in the states of Alabama and Georgia contain approximately 19.0 million tons of kaolin suitable for use in production of our kaolin-based proppants.

We utilize our own Northern White sand, CARBO NORTHERN-WHITE, and purchase third party wet processed sand reserves for our sand processing facility in Marshfield, Wisconsin, which supplies raw frac sand to the proppant market.

Ceramic Production Process

Ceramic proppants are made by grinding or dispersing ore to a fine powder, combining the powder into small pellets and firing the pellets in a rotary kiln. We use three different methods to produce ceramic proppant. Industrial ceramic media follows a similar process.

Our plant in McIntyre, Georgia uses a dry process, which utilizes clay, bauxite, bauxitic clay or kaolin. The raw material is ground, pelletized and screened. The manufacturing process is completed by firing the product in a rotary kiln.

Our plants in Eufaula, Alabama and Toomsboro, Georgia use a wet process, which starts with kaolin that is formed into slurry. The slurry is then pelletized in a dryer and the pellets are then fired in a rotary kiln.

The portion of our plant in New Iberia, Louisiana that manufactures ceramic proppant, as well as one line at our Eufaula, Alabama facility, uses a proprietary manufacturing process associated with the Company’s KRYPTOSPHERE product line.

Our rotary kilns are primarily heated by the use of natural gas.

Due to market conditions, the Company’s current forecast is to only operate its McIntyre, Georgia and New Iberia, Louisiana plants.

Patent Protection and Intellectual Property

We make ceramic proppant and ceramic media used in foundry, grinding and scouring processes by processes and techniques that involve a high degree of proprietary technology, some of which is protected by patents.

We own multiple patents in the United States and various foreign countries that relate to different types of ceramic proppant and production methods used for ceramic proppant and ceramic media; however, depending on market conditions, production of products pursuant to these patents may not necessarily constitute a material portion of our output. We also own multiple U.S. and foreign patents that relate to methods for the detection of subterranean fractures and material, including gravel packs, in the near-borehole region. We also own multiple U.S. patents that relate to detectable proppant.

During 2014 and 2015, we obtained three U.S. patents relating to our KRYPTOSPHERE manufacturing process, during 2017, we obtained one U.S. patent covering the KRYPTOSPHERE product, and during 2018, we obtained another U.S. patent covering the KRYPTOSPHERE product, each of which expire in 2031, and another U.S. patent relating to our KRYPTOSPHERE manufacturing process, which expires in 2036. Also, during 2018, we obtained two U.S. patents relating to our GUARD product lines, which expire in 2035 and one U.S. patent relating to our FUSION product line, which expires in 2037. WeIn ~~expect~~2019, ~~these~~we ~~patents~~obtained one U.S. patent relating to ~~provide~~our ~~assistance~~CARBOAIR product line, which expires in ~~the~~2036, ~~future~~one ~~sales~~U.S. ofpatent ~~these~~relating to our SCALEGUARD product ~~lines~~line, which expires in 2036, and two U.S. patents relating to our FUSION product line, which expire in 2036. During 2015, 2016, 2017, ~~and~~ 2018, and 2019 we obtained ~~six~~nine U.S. patents, which expire in 2033, 2034, 2035 and 2036 and relate to our far-field proppant detection products, systems and methods which relate to our iON product line and the QUANTUM service line,. We ~~which~~expect ~~are~~at ~~still~~least ~~under~~a ~~development~~portion of these patents to aid in the future sales of these product and service lines.

We own ~~multiple~~additional U.S. patents and pending U.S. patent applications (together with a number of counterpart applications pending in foreign jurisdictions). A portion of the U.S. patents and patent applications relating to our Oil and Gas business cover ceramic proppant, detectable proppant, processes for making ceramic proppant and detectable proppant, tracers for detecting produced fluids, diversion particles, detection of subterranean fractures, and our KRYPTOSPHERE, GUARD, FUSION, CARBOAIR, and NANOMITE product lines and methods for making and using these products. Another portion of the U.S. patent applications cover non-oilfield or industrial products, such as water treatment compositions, foundry media, building materials and ceramic media for use in solar power plants. The applications are in various stages of the patent prosecution process, and patents may not issue on such applications in any jurisdiction for some time, if they issue at all.

AGPI owns three U.S. patents, which expire in 2026, 2027 and 2034 and relate to construction of secondary containment areas. In addition, AGPI owns four U.S. patents, which expire in 2030 and 2031 and relate to polyurea-encapsulated tank bases. AGPI also owns multiple U.S. patent applications, each of which relates to tank bases, equipment bases, portable containments, or components useful in containment areas in upstream, midstream and downstream environments.8

We believe that our patents have historically been important in enabling us to compete in the market to supply proppant to the natural gas and oil industry. We intend to enforce, and have in the past vigorously enforced, our patents. We may from time to time be involved in litigation to determine the enforceability, scope and validity of our patent rights. In addition to patent rights, and perhaps more notably, we use a significant amount of trade secrets, or “know-how,” and other proprietary information and technology in the conduct of our business. None of this “know-how” and technology is licensed from third parties. However, we have negotiated a long-term license for some third-party intellectual property used or jointly developed in connection with our QUANTUM service line.

Seasonality

Historically, we have experienced higher levels of proppant and environmental sales activities during warmer weather periods and less during colder weather months in the northern and eastern United States. In addition, sales activities can be decreased by the spring snow and ice “break-up” in Canada, North Dakota, Montana, and the Northeast U.S., as well as the winter holidays in December and January. Our industrial ceramic media products are not typically impacted by seasonality.

Environmental and Other Governmental Regulations

We believe that our operations are in substantial compliance with applicable domestic and foreign federal, state and local environmental and safety laws and regulations.

Existing federal environmental requirements such as the Clean Air Act and the Clean Water Act, as amended, impose certain restrictions on discharge of air and water pollutants from our operations via permits and regulations. Those pollutants include volatile organic compounds, nitrogen oxides, sulfur dioxide, particulate matter, storm water and wastewater discharges and other by-products. In addition to meeting environmental requirements for existing operations, the Company must also demonstrate compliance with environmental regulations in order to obtain any required permits prior to any future expansion. The United States Environmental Protection Agency (“EPA”) and state programs require covered facilities to obtain individual permits or have coverage under an EPA general permit issued to groups of facilities. A number of federal and state agencies, including but not limited to, the EPA, the Texas Commission on Environmental Quality, the Louisiana Department of Environmental Quality, the Alabama Department of Environmental Management, the Wisconsin Department of Natural Resources, and the Environmental Protection Division of the Georgia Department of Natural Resources promulgate and enforce environmental regulations applicable to our operations in the states in which we do business. Historically we have been able to obtain permits, where necessary, to build new facilities and modify existing facilities that allow us to continue compliant operations. Obtaining these permits in a timely manner will continue to be an important factor in our ability to do so in the future.

Employees

As of December 31, ~~2018~~2019, we had ~~407~~349 employees worldwide. In addition to the services of our employees, we employ the services of consultants as required. Our employees are not represented by labor unions. There have been no work stoppages or strikes during the last three years that have resulted in the loss of production or production delays. We believe our relations with our employees are satisfactory.

Our operations require the services of employees having the technical training and experience necessary to achieve proper operational results. As a result, our operations depend, to a considerable extent, on the continuing availability of such personnel. From time to time, shortages of qualified personnel have occurred in our industry. Additionally, we may experience employee attrition as a result of the Chapter 11 Cases. If we should suffer any material loss of personnel or be unable to employ additional or replacement

personnel with the requisite level of training and experience to adequately operate our equipment, our operations could be materially adversely affected.

Risk Factors

You should consider carefully the trends, risks and uncertainties described below and other information in this Form 10-K and subsequent reports filed with the SEC before making any investment decision with respect to our securities. If any of the following trends, risks or uncertainties actually occurs or continues, our business, financial condition or operating results could be materially adversely affected, the trading prices of our securities could decline and you could lose all or part of your investment.

Risks Relating to Our Chapter 11 Proceedings

On March 29, 2020, the Company and certain of its U.S. subsidiaries filed voluntary petitions commencing the Chapter 11 Cases under the Bankruptcy Code. The Chapter 11 Cases and the Restructuring may have a material adverse impact on our business, financial condition, results of operations, and cash flows. In addition, the Chapter 11 Cases and the Restructuring are likely to have a material adverse impact on the trading price of our common stock and ultimately are expected to result in the cancellation of our common stock.

In the fall of 2019, we engaged an investment bank and financial and legal advisors to assist us in, among other things, exploring strategic alternatives, forecasting cash flow, analyzing and preserving liquidity, and implementing contingency planning for a potential

in-court process were the Company unsuccessful in consummating a strategic alternative out of court solution. These restructuring efforts led to the execution of the RSA and commencement of the Chapter 11 Cases in the Bankruptcy Court on March 29, 2020.

The Chapter 11 Cases could have a material adverse effect on our business, financial condition, results of operations and liquidity. Bankruptcy Court protection also may make it more difficult to retain management and the key personnel necessary to our business. In addition, during the period of time we are involved in a bankruptcy proceeding, our clients and suppliers might lose confidence in our ability to reorganize our business successfully and may discontinue conducting business with us or seek to establish alternative commercial relationships.

Other significant risks include or relate to the following:

•

delays in the Chapter 11 Cases;

•

our ability to consummate the Plan;

•

our ability to achieve our stated goals and continue as a going concern;

•

the effects of the filing of the Chapter 11 Cases on our business and the interest of various constituents, including our shareholders, customers, suppliers, service providers, and employees;

•

the high costs of bankruptcy proceedings and related advisory costs to effect our reorganization;

•

our ability to maintain relationships with customers, suppliers, service providers, employees and other third parties as a result of the Chapter 11 Cases;

•

our ability to maintain contracts that are critical to our operations;

•

our ability to fund and execute our business plan;

•

our ability to obtain acceptable and appropriate financing;

•

Bankruptcy Court rulings in the Chapter 11 Cases as well as the outcome of the Chapter 11 Cases in general;

•

the length of time that we will operate with Chapter 11 protection and the continued availability of operating capital during the pendency of the proceedings;

•

our ability to confirm and consummate a plan of reorganization with respect to the Chapter 11 Cases, views and objections of creditors and other parties in interest that may make it difficult to consummate a plan in a timely manner;

•

the ability of third parties to seek and obtain Bankruptcy Court approval to terminate or shorten the exclusivity period for us to propose and confirm a plan of reorganization, to appoint a U.S. trustee or to convert the Chapter 11 Cases to cases under Chapter 7 of the Bankruptcy Code (“Chapter 7”);

•

third-party motions in the Chapter 11 Cases, which may interfere with our ability to consummate the Plan; and

•

the potential adverse effects of the Chapter 11 Cases on our liquidity and results of operations.

Because of the risks and uncertainties associated with the Chapter 11 Cases, we cannot predict or quantify the ultimate impact that events occurring during the Chapter 11 Cases may have on our business, cash flows, liquidity, financial condition and results of operations, nor can we predict the ultimate impact that events occurring during the Chapter 11 Cases may have on our corporate or capital structure, although we expect such proceedings to result in the cancellation of our common stock.

Delays in the Chapter 11 Cases may increase the risks of our being unable to reorganize our business and emerge from bankruptcy and may increase our costs associated with the bankruptcy process.

The RSA contemplates the consummation of the Plan through an orderly pre-negotiated plan of reorganization, but there can be no assurance that we will be able to consummate the Plan. A prolonged Chapter 11 proceeding could adversely affect our relationships with customers, suppliers, service providers, and employees, among other third parties, which in turn could adversely affect our

business, competitive position, financial condition, liquidity and results of operations and our ability to continue as a going concern. A weakening of our financial condition, liquidity and results of operations could adversely affect our ability to implement the Plan (or any other plan of reorganization). If we are unable to consummate the Plan, we may be forced to liquidate our assets.

In addition, the occurrence of the effective date of the Plan is subject to certain conditions and requirements that may not be satisfied or waived.

The Plan may not become effective.

The Plan may not become effective because it is subject to the satisfaction of certain conditions precedent, some of which are beyond our control. There can be no assurance that such conditions will be satisfied or waived and, therefore, that the Plan will become effective and that we will emerge from the Chapter 11 Cases as contemplated by the Plan. If the effective date of the Plan is delayed, we may not have sufficient cash available to operate our business. In that case, we may need new or additional post-petition financing, which may increase the cost of consummating the Plan. There is no assurance of the terms on which such financing may be available or if such financing will be available. If the transactions contemplated by the Plan are not completed, it may become necessary to amend the Plan. The terms of any such amendment are uncertain and could result in material additional expense and result in material delays to the Chapter 11 Cases.

We may not be able to obtain Bankruptcy Court confirmation of the Plan or may have to modify the terms of the Plan.

Even if the Plan is approved by each class of holders of claims and interests entitled to vote (a “Voting Class”), the Bankruptcy Court, which, as a court of equity, may exercise substantial discretion and may choose not to confirm the Plan. Section 1129 of the Bankruptcy Code requires, among other things, a showing that confirmation of the Plan will not be followed by liquidation or the need for further financial reorganization for us, and that the value of distributions to dissenting holders of claims and interests will not be less than the value such holders would receive if we, the debtors, liquidated under Chapter 7. Although we believe that the Plan will satisfy such tests, there can be no assurance that the Bankruptcy Court will reach the same conclusion.

Confirmation of the Plan will also be subject to certain conditions. These conditions may not be met and there can be no assurance that the Supporting Lenders will agree to modify or waive such conditions. Further, changed circumstances may necessitate changes to the Plan. Any such modifications could result in less favorable treatment than the treatment currently anticipated to be included in the Plan based upon the agreed terms of the RSA. Such less favorable treatment could include a distribution of property (including the new common stock that would be issued to the Supporting Lenders upon our emergence from bankruptcy) to the class affected by the modification of a lesser value than currently anticipated to be included in the Plan or no distribution of property whatsoever under the Plan. Changes to the Plan may also delay the confirmation of the Plan and our emergence from bankruptcy, which could result in, among other things, incurred costs and expenses to the estates of the debtors.

Even if a Chapter 11 plan of reorganization is consummated, we may not be able to achieve our stated goals and continue as a going concern.

Even if the Plan, or any other plan of reorganization, is consummated, we may continue to face a number of risks, such as further deterioration or other changes in economic conditions, changes in our industry, changes in demand for our services and increasing expenses. Accordingly, we cannot guarantee that the Plan, or any other plan of reorganization, will achieve our stated goals.

Furthermore, even if our debts are reduced through a plan of reorganization, we may need to raise additional funds through public or private debt or equity financing or other various means to fund our business after the completion of the Chapter 11 Cases. Our access to additional financing may be limited, if it is available at all. Therefore, adequate funds may not be available when needed or may not be available on favorable terms.

The Plan or another plan of reorganization that we may implement will be based upon assumptions and analyses developed by us. If these assumptions and analyses prove to be incorrect, we may not be able to successfully execute such plan.

The Plan or any other plan of reorganization that we may implement will affect both our capital structure and the ownership, structure and operation of our business and will reflect assumptions and analyses based on our experience and perception of historical trends, current conditions and expected future developments, as well as other factors that we consider appropriate under the circumstances. Whether actual future results and developments will be consistent with our expectations and assumptions depends on a number of factors, including but not limited to (i) our ability to substantially change our capital structure; (ii) our ability to obtain adequate liquidity and financing sources; (iii) our ability to maintain customers’ confidence in our viability as a continuing entity and to attract and retain sufficient business from them; (iv) our ability to retain key employees, and (v) the overall strength and stability of general economic conditions and conditions of the our industry. The failure of any of these factors could materially adversely affect the successful reorganization of our business.

In addition, the Plan or any other plan of reorganization, will rely upon financial projections, including with respect to revenues, capital expenditures, debt service and cash flow. Financial forecasts are necessarily speculative, and it is possible that one or more of the assumptions and estimates that are the basis of these financial forecasts will not be accurate. In our case, the forecasts are even more speculative than normal, because they involve fundamental changes in the nature of our capital structure. Accordingly, we expect that our actual financial condition and results of operations may differ, perhaps materially, from what we have anticipated. Consequently, there can be no assurance that the results or developments contemplated by any plan of reorganization we may implement will occur or, even if they do occur, that they will have the anticipated effects on us or our business or operations. The failure of any such results or developments to materialize as anticipated could materially adversely affect the successful execution of our plan of reorganization.

Our cash flows may not provide sufficient liquidity during the Chapter 11 Cases. Our long-term liquidity requirements and the adequacy of our capital resources are difficult to predict at this time.

Our ability to fund our operations and our capital expenditures requires a significant amount of cash. Our current principal sources of liquidity include the available borrowing capacity under the DIP Facility and cash flow generated from operations. If our cash flow from operations decreases, we may not have the ability to expend the capital necessary to maintain our current operations, negatively impacting our future revenues.

We face uncertainty regarding the adequacy of our liquidity and capital resources and have limited, if any, access to additional financing. In addition to the cash requirements necessary to fund ongoing operations, we have incurred significant professional fees and other costs in connection with preparation for the Chapter 11 proceedings and expect that we will continue to incur significant professional fees and costs throughout our Chapter 11 proceedings. As a result, we may not be able to comply with the covenants of the DIP Facility, and our cash on hand and cash flow from operations may not be sufficient to continue to fund our operations and allow us to satisfy our obligations related to the Chapter 11 Cases until we are able to emerge from the Chapter 11 Cases.

Our liquidity, including our ability to meet our ongoing operational obligations, is dependent upon, among other things: (i) our ability to comply with the terms and conditions of the DIP Facility agreements, (ii) our ability to comply with the terms and conditions of any cash collateral order that may be entered by the Bankruptcy Court in connection with the Chapter 11 Cases, (iii) our ability to maintain adequate cash on hand, (iv) our ability to generate cash flow from operations, (v) our ability to confirm and consummate the Plan or another alternative restructuring transaction and (vi) the cost, duration and outcome of the Chapter 11 Cases.

We may be unable to comply with restrictions or with budget, liquidity, or other covenants imposed by the agreements governing the DIP Facility. Such non-compliance could result in an event of default under the terms of the DIP Facility that, if not cured or waived, would have a material adverse effect on our business, financial condition and results of operations.

The DIP Facility requires that we comply with general affirmative and negative covenants such as prohibiting us from incurring or permitting debt, investments, liens or dispositions unless specifically permitted. Our ability to comply with these provisions may be affected by events beyond our control and our failure to comply, or obtain a waiver in the event we cannot comply with a covenant, could result in an event of default under the DIP Facility and permit the lenders thereunder to accelerate the loans and otherwise exercise remedies allowable by the agreements governing the DIP Facility.

Competing plans of reorganization, which could have less favorable terms or result in significant litigation and expenses.

Parties in interest may seek to file alternative plans of reorganization. An alternative plan of reorganization could contemplate us continuing as a going concern, us being broken up, us or our assets being acquired by a third party, us being merged with a competitor, or some other proposal. There can be no assurances that recoveries under any such alternative plan would be as favorable to creditors as the Plan. In addition, the proposal of competing plans of reorganization may entail significant litigation and significantly increase the expenses of administration of the Chapter 11 Cases, which could deplete creditor recoveries under any plan.

As a result of the Chapter 11 Cases, our historical financial information may not be indicative of our future performance, which may be volatile.

During the Chapter 11 Cases, we expect our financial results to continue to be volatile as restructuring activities and expenses significantly impact our consolidated financial statements. As a result, our historical financial performance is likely not indicative of our financial performance after the date of the filing of the Chapter 11 Cases. In addition, if we emerge from Chapter 11, the amounts reported in subsequent consolidated financial statements may materially change relative to our historical consolidated financial statements, including as a result of revisions to our operating plans pursuant to the Plan. We expect that we will be required to adopt the fresh start accounting rules, in which case our assets and liabilities will be recorded at fair value as of the fresh start reporting date, which may differ materially from the recorded values of assets and liabilities on our consolidated balance sheets and our financial results after the application of fresh start accounting may be different from historical trends.

Trading in our securities during the pendency of the Chapter 11 Cases is highly speculative and poses substantial risks. The Plan will result in the cancellation of our common stock.

Under the Plan, all existing equity interests in the Company will be extinguished. Amounts invested by the holders of our common stock will not be recoverable and such securities will have no value. Trading prices for our common stock bear no relationship to the actual recovery, if any, by the holders thereof in the Chapter 11 Cases. Accordingly, we urge extreme caution with respect to existing and future investments in our existing common stock.

If the RSA is terminated, our ability to confirm and consummate the Plan could be materially and adversely affected.

The RSA contains a number of termination events, upon the occurrence of which certain parties to the RSA may terminate the agreement. If the RSA is terminated as to all parties thereto, each of the parties thereto will be released from its obligations in accordance with the terms of the RSA. Such termination may result in the loss of support for the Plan by the parties to the RSA, which could adversely affect our ability to confirm and consummate the Plan. If the Plan is not consummated, there can be no assurance that the Chapter 11 Cases would not be converted to Chapter 7 liquidation cases or that any new Plan would be as favorable to holders of claims against the Debtors as contemplated by the RSA.

In certain instances, a Chapter 11 case may be converted to a case under Chapter 7 of the Bankruptcy Code.

Upon a showing of cause, the Bankruptcy Court may convert the Chapter 11 Cases to a case under Chapter 7. In such event, a Chapter 7 trustee would be appointed or elected to liquidate our assets for distribution in accordance with the priorities established by the Bankruptcy Code. We believe that liquidation under Chapter 7 would result in smaller distributions being made to our creditors than those provided for in the Plan because of (i) the likelihood that the assets would have to be sold or otherwise disposed of in a distressed fashion over a short period of time rather than in a controlled manner and as a going concern, (ii) additional administrative expenses involved in the appointment of a Chapter 7 trustee, and (iii) additional expenses and claims, some of which would be entitled to priority, that would be generated during the liquidation and from the rejection of executory contracts in connection with a cessation of operations.

We may be subject to claims that will not be discharged in the Chapter 11 Cases, which could have a material adverse effect on our financial condition and results of operations.

The Bankruptcy Code provides that the confirmation of a plan of reorganization discharges a debtor from substantially all debts arising prior to consummation of a plan of reorganization. With few exceptions, all claims that arose prior to March 29, 2020 or before consummation of the Plan (i) would be subject to compromise and/or treatment under the Plan and/or (ii) would be discharged in accordance with the Bankruptcy Code and the terms of the Plan. Any claims not ultimately discharged pursuant to the Plan could be asserted against the reorganized entities and may have an adverse effect on our financial condition and results of operations on a post‑reorganization basis.

The Chapter 11 Cases limit the flexibility of our management team in running our business.

While we operate our business as debtor-in-possession under supervision by the Bankruptcy Court, we are required to obtain the approval of the Bankruptcy Court and, in some cases, the Supporting Lenders, prior to engaging in activities or transactions outside the ordinary course of business. Bankruptcy Court approval of non-ordinary course activities entails preparation and filing of appropriate motions with the Bankruptcy Court, negotiation with the creditors’ committee (if any) and other parties-in-interest and one or more hearings. The creditors’ committees and other parties-in interest may be heard at any Bankruptcy Court hearing and may raise objections with respect to these motions.

This process may delay such-non ordinary course transactions and limit our ability to respond in a timely manner to adapt to changing market or industry conditions or to take advantage of certain opportunities. Furthermore, in the event the Bankruptcy Court does not approve a proposed activity or transaction, we would be prevented from engaging in activities and transactions that we believe to be beneficial to us.

The commencement of the Chapter 11 Cases has consumed and will continue to consume a substantial portion of the time and attention of our management and will impact how our business is conducted, which may have an adverse effect on our business and results of operations.

The requirements of the Chapter 11 Cases have consumed and will continue to consume a substantial portion of our management’s time and attention and leave them with less time to devote to the operation of our business. This diversion of attention may materially adversely affect the conduct of our business and, as a result, our financial condition and results of operations.

We may experience employee attrition as a result of the Chapter 11 Cases.

As a result of the Chapter 11 Cases, we may experience employee attrition, and our employees may face considerable distraction and uncertainty. A loss of key personnel or material erosion of employee morale could adversely affect our business and results of operations. Our ability to engage, motivate and retain key employees or take other measures intended to motivate and incentivize key employees to remain with us through the pendency of the Chapter 11 Cases is limited by restrictions on implementation of incentive programs under the Bankruptcy Code. The loss of services of members of our senior management team could impair our ability to execute our strategy and implement operational initiatives, which could have a material adverse effect on our financial condition, liquidity and results of operations.

On the effective date of the Plan, the composition of our board of directors will change substantially.

Under the Plan, the composition of our board of directors will change substantially. Pursuant to the Plan, our new board of directors will be appointed by the Supporting Lenders under the RSA in consultation with our management, and the numbers of directors will also be determined by the Supporting Lenders. Accordingly, almost all of our board members will be new to the Company. Any new directors are likely to have different backgrounds, experiences and perspectives from those individuals who previously served on the board of directors and, thus, may have different views on the issues that will determine our future. As a result, our future strategy and plans may differ materially from those of the past.

Adverse publicity in connection with the Chapter 11 Cases or otherwise could negatively affect our businesses.

Adverse publicity or news coverage relating to us, including, but not limited to, publicity or news coverage in connection with the Chapter 11 Cases, may negatively impact our efforts to establish and promote name recognition and a positive image after emergence from the Chapter 11 Cases.

Risks Related to Our Business, Capital Resources and Organization

Our business and financial performance largely depends on the level of activity in the natural gas and oil industries.

Our operations are materially dependent upon the levels of activity in natural gas and oil exploration, development and production. More specifically, the demand for our products is related to the number of natural gas and oil wells completed in geologic formations where ceramic or sand proppants are used in fracture treatments. These activity levels are affected by both short-term and long-term trends in oil and natural gas prices. In recent years, oil and natural gas prices and, therefore, the level of exploration, development and production activity, have experienced significant fluctuations. Worldwide economic, political and military events, including war, terrorist activity, events in the Middle East and initiatives by OPEC, have contributed, and are likely to continue to contribute, to price volatility. Despite recent initiatives to curb supply, the global supply of oil is currently at historically high levels, and there is potential for geopolitical and regulatory events, such as normalization of trade relations with the Islamic Republic of Iran, to further increase the supply of oil. Additionally, warmer than normal winters in North America and other weather patterns may adversely impact the short-term demand for natural gas and, therefore, demand for our products and services. Natural gas prices experienced a significant decline during 2012 and, although they have increased since then, remain relatively low on a historic basis, resulting in generally lower gas drilling activity. Further, the price of oil declined precipitously from the second half of 2014 through mid-2016 and, although the price rebounded from its low in the first half of 2018, it decreased again in the second half and ~~still~~moreover, in the first quarter of 2020, oil prices fell approximately 20% in a single day. In March 2020, the price of oil fell even further due to a dispute over production levels between Russia and Saudi Arabia, as a result of which Saudi Arabia increased its production to record levels. While an agreement as to production cuts was reached, the global crude oil market remains significantly oversupplied, and oil prices could remain at ~~weakened~~current levels, or decline further, for an extended period of time. These events, combined with the continued outbreak of COVID-19 resulting in significant storage constraints due to lack of demand, contributed to a sharp drop in prices for oil in 2020 to-date. This reduction in oil and natural gas prices has depressed the level of natural gas and oil exploration, development, production and well completions activity, resulting in significantly reduced demand and pricing for our base ceramic and sand products. In addition and because of the depressed commodity prices, we have seen a significant increase in the use of very low quality in-basin sand at the expense of lower production for unconventional wells, which have extremely low quality reservoirs. This decline has had, and continues to have, a significant adverse impact on our results. If oil and natural gas prices and well completion activity do not materially improve and/or demand for our products does not otherwise increase, this decline could reasonably be expected to have a material adverse effect on our financial condition or operations, including, but not limited to, the temporary idling of all, or a portion of all, of our facilities utilized for this sector of our business until such time as market conditions improve.

1017

Recent declines in crude oil prices to record low levels as a result of the outbreak of the novel strain of coronavirus (“COVID-19”) and a significantly oversupplied crude oil market have negatively impacted, and are expected to continue to negatively impact, demand for our products and services resulting in a material negative impact on our results of operations, financial position and liquidity.

In December 2019, COVID-19 was reported to have surfaced in Wuhan, China and has since spread to other parts of the world. The outbreak of COVID-19 in the United States and globally, together with government and private sector responsive actions, have, and are expected to continue to, adversely affect both the price of and demand for crude oil, the demand for certain of our products and services and the continuity of our and our customers’ business operations.

It is currently impossible to predict the effect and ultimate impact of the COVID-19 pandemic as the situation is rapidly evolving. In March 2020, the President of the United States declared the COVID-19 pandemic a national emergency, invoking powers under the Stafford Act, the legislation that directs federal emergency disaster response. A significant majority of states as well as local jurisdictions have imposed, and others in the future may impose, “shelter-in-place” orders, quarantines, executive orders and similar government orders and restrictions for their residents to control the spread of COVID-19. Such orders or restrictions, and the perception that such orders or restrictions could occur, have resulted in business closures, work stoppages, slowdowns and delays, work-from-home policies, travel restrictions and cancellation of events, among other effects.

While the U.S. Department of Homeland Security and various local orders have identified the energy industry as critical to the U.S. infrastructure, generally allowing certain of our and our customers’ operations to continue, our operations, and those of our customers, have been and will likely continue to be disrupted in various ways. For example, in an effort to minimize the spread of illness, we and our customers have implemented various worksite restrictions in order to minimize contact among personnel, and have also required employees to quarantine who have become ill or experienced COVID-19-related symptoms. Travel restrictions and flight cancellations have also slowed personnel travel and equipment delivery to certain customer locations. In addition, the COVID-19 outbreak poses a risk of disruptions to our supply chain if a supplier were to experience production or delivery constraints due to the effects of COVID-19. Disruptions of this type and others could continue and increase for the foreseeable future. For example, cases of COVID-19 in the workplace environments of our customers have occurred, and a widespread outbreak of COVID-19 in such an environment could result in a cessation of operations which would further depress demand for our products and services. Finally, although our non-idled manufacturing and service facilities generally remain open and operational as of the date of filing of this Annual Report on Form 10-K, governmental mandates or the illness or absence of a substantial number of employees could require that we temporarily close one or more of such facilities, or may prohibit or significantly restrict us, our customers and third-party providers upon whom we and they rely from remaining operational.

In addition, we have implemented work-from-home policies for certain employees. The effects of shelter-in-place orders and our work-from-home policies may negatively impact productivity and disrupt our business, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course.

Contemporaneously with the widespread outbreak of COVID-19 in the United States, Saudi Arabia announced a material increase in crude oil production in response to a dispute with Russia over crude oil production levels, resulting in global oil markets being significantly oversupplied, particularly in light of the reduced demand resulting from the COVID-19 pandemic. As a result, the price of West Texas Intermediate crude oil declined precipitously beginning in the middle of March, reaching a low price of beneath $0.00 per barrel on April 20, 2020. In response, a number of our exploration and production company customers announced significant reductions in capital spending for drilling and other projects on which our products and services would be used. These reductions in spending and activity levels have negatively impacted, and we expect they will continue to negatively impact, demand for our products and services, the prices we can charge for those products and services and, as a result, our results of operations, liquidity and financial condition. While an agreement as to production cuts was reached, the global crude oil market remains significantly oversupplied, and whether the agreed production cuts will be sufficient to realign supply and demand in light of the COVID-19 pandemic and the impact on crude oil prices.

The effect of the COVID-19 pandemic has also resulted in significant disruption of global financial markets. For companies like ours in the energy industry, this disruption has been exacerbated by the global crude oil supply and demand imbalance and resulting decline in crude oil prices, and has significantly impacted the value of our common stock and which may reduce our ability to access capital in the bank and capital markets, which could in the future negatively affect our liquidity. In addition, a recession or long-term market correction, resulting from the COVID-19 pandemic could in the future further materially impact the value of our common stock, impact our access to capital and affect our business in the near and long-term.

The COVID-19 pandemic continues to rapidly evolve. The extent to which COVID-19 and depressed crude oil prices impacts our results, financial position and liquidity will depend on future developments, which are highly uncertain and cannot be predicted.

We may not have sufficient cash and/or be able to access liquidity alternatives in the credit and capital markets to meet our liquidity needs.

~~Our~~Prior to filing the Chapter 11 Cases, our primary sources of liquidity ~~are~~were cash on hand and cash flow from operations. Our ability to fund our working capital and capital expenditures and other obligations depends on our future operating performance and cash from operations and other liquidity-generating transactions, which are in turn subject to prevailing oil and natural gas prices, economic conditions and other factors, many of which are beyond our control.

If our future operating performance falls materially below our expectations, our plans prove to be materially inaccurate, or industry conditions do not materially improve, we may require additional financing. Even if additional or alternative financing becomes available to us, future financing transactions may significantly increase the Company’s interest expense, which could in turn reduce our financial flexibility and our ability to fund other activities, and could make us more vulnerable to changes in operating performance or economic downturns generally. The inability to generate sufficient cash, modify any of our ~~New~~existing ~~Credit~~or ~~Agreement~~future debt arrangements, or obtain replacement or additional financing, or an event of default under our ~~New~~existing ~~Credit~~or ~~Agreement~~future debt arrangements, could have a material adverse effect on our financial condition. Further, for the duration of the Chapter 11 Cases, we will be subject to various additional risks, including the inability to maintain or obtain sufficient financing sources for operations, to fund the plan of reorganization and to meet future obligations, including increased legal and other professional costs associated with the Chapter 11 Cases and our reorganization. Further, if the transactions contemplated by the Plan are not completed such that the effective date of the Plan occurs prior to the maturity of the DIP Facility, we may need to refinance the DIP Facility. We may not be able to obtain any such financing on acceptable terms, or at all.

We therefore cannot provide any assurance that we will be able to access the capital or credit markets on acceptable terms or timing, or at all. Access to the capital markets and the cost and availability of credit may be adversely affected by factors beyond our control, including turmoil in the financial services industry, volatility in securities trading markets, the continuing downturn in the oil and gas industry and general economic conditions. Currently, we do not qualify as a “well-known seasoned issuer,” which otherwise would allow us to, among other things, file automatically effective shelf registration statements. Now, even if we are able to access the public capital markets, any attempt to do so could be more expensive or subject us to significant delays when compared with previous periods.

Our business and financial performance has suffered and could suffer further if the levels of hydraulic fracturing continue to decline or cease as a result of the low commodity price of oil and natural gas, development of new processes, increased regulation or a continued decrease in drilling activity.

A large portion of our products are proppants used in the completion and re-completion of natural gas and oil wells through the process of hydraulic fracturing. Completion activity is directly impacted by the price of oil and natural gas. In addition, demand for our proppants is substantially higher in the case of horizontally drilled wells, which allow for multiple hydraulic fractures within the same well bore but are more expensive to develop than vertically drilled wells. A reduction in horizontal drilling or the development of new processes for the completion of natural gas and oil wells leading to a reduction in, or discontinuation of the use of, hydraulic fracturing could cause a decline in demand for our products. Additionally, increased regulation or environmental restrictions on hydraulic fracturing or the materials used in this process could negatively affect our business by increasing the costs of compliance or resulting in operational delays, which could cause operators to abandon the process due to commercial impracticability. Moreover, future federal, state, local or foreign laws or regulations could otherwise limit or ban hydraulic fracturing. Several states in which our customers operate have adopted, or are considering adopting, regulations that have imposed, or could impose, more stringent permitting, transparency, disposal and well construction requirements on hydraulic fracturing operations. Some states, such as New York, have banned the process of hydraulic fracturing altogether. Any of these events could have a material adverse effect on our results of operations and financial condition. As stated elsewhere, the upstream oil and natural gas industry is in the midst of a severe contraction, resulting in a significant reduction in horizontal drilling and further resulting in a material decline in demand for our products and services. Oil and natural gas prices have recently experienced record declines and are currently at record low levels in response to dramatic supply and demand uncertainty. In response, several exploration and production companies have recently announced plans to reduce their capital budgets and activity levels. We expect these changes will adversely affect the revenue, profitability, and cash flow from and, ultimately the financial position of, our business. A significant downturn in the oil and gas industry could cause a reduction in demand for oilfield services and could hurt our financial condition, results of operations and cash flows.

We face distribution and logistical challenges in our business.

As oil and natural gas prices fluctuate, our customers may shift their focus back and forth between different resource plays, some of which can be located in geographic areas that do not have well-developed transportation and distribution infrastructure systems. Transportation and logistical operating expenses continue to comprise a significant portion of our total delivered cost of sales. Therefore, serving our clients in these less-developed areas presents distribution and other operational challenges that affect our sales and negatively impact our operating costs. Disruptions in transportation services, including shortages of rail cars or a lack of rail transportation services or developed infrastructure, could affect our ability to timely and cost effectively deliver products to our customers and could provide a competitive advantage to competitors located in closer proximity to customers. Additionally, increases in the price of diesel fuel could negatively impact operating costs if we are unable to pass those increased costs along to our customers. 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 results of operations and financial condition.

We operate in an increasingly competitive market.

The proppant market is highly competitive. We compete with other domestic and international suppliers of ceramic proppant, as well as with suppliers of sand for use as proppant, in the hydraulic fracturing of natural gas and oil wells. The expiration of key patents owned by the Company has resulted in additional competition in the market for ceramic proppant. The entry of additional competitors into the market, and/or a surge in the level of ceramic proppant imports into North America from existing competitors, could have a material adverse effect on our results of operations and financial condition.

Our industrial products have competitors across several industries we sell into. Competition for products in the North American foundry market includes several ceramic media manufacturers. There are also a number of competitors in the grinding market that primarily manufacture their ceramic grinding products in China. We believe our industrial products are competitively priced, are of higher quality and our customer experience is better than the competition.

Our environmental products have a large number of competitors across the United States. There are few barriers to entry in this market, however we do own key patents for some of our environmental products. We believe there are several key factors that drive customers to purchase our environmental products over the competition including centralized manufacturing, on time delivery, competitive pricing, a focus on customer satisfaction, and excellent technical support.

Adverse changes to these key factors or a shift in customer preferences to our competitor's products could have a material adverse effect on our results of operations and financial condition.

We have been and may continue to be adversely affected by decreased demand for our proppant or the development by our competitors of alternative proppants.

Ceramic proppant is a premium product capable of withstanding higher pressure and providing more highly conductive fractures than mined sand, which is the most commonly used proppant type. We continue to see operators that have traditionally used ceramic proppant shifting to use mined sand instead. Despite recently improving commodity prices in the oil and natural gas industry, continued pressure on operators to reduce cost or to evaluate returns on a shorter horizon has had a detrimental impact on the demand for ceramic proppant, which is a higher cost product than mined sand. Although we believe that the use of quality ceramic proppant in appropriate geologic formations typically generates higher production rates and more favorable long-term production economics than mined sand, the shifting of customer demand to lower cost products, such as mined sand, has had an adverse effect on our results of operations and its continuation could have a material adverse effect on our financial condition. The development and use of alternative proppant could also cause a decline in demand for our products, and could have a material adverse effect on our results of operations and financial condition.

The outstanding indebtedness under our New Credit Agreement is secured by a substantial portion of our domestic assets and guaranteed by our two domestic operating subsidiaries, subject to certain exceptions.20

~~The~~We ~~outstanding~~have ~~indebtedness~~no ~~under~~plans ~~our~~to ~~New~~pay ~~Credit Agreement is secured by (i) a pledge of all accounts receivable and inventory, (ii)~~ cash individends ~~certain accounts, (iii) domestic distribution assets residing~~ on ~~owned real property, (iv)~~ our ~~Marshfield,~~new ~~Wisconsin~~common ~~and~~stock ~~Toomsboro,~~for ~~Georgia plant facilities and equipment, and (v) certain real property interests in mines and minerals.

Any of these actions could, individually or in the aggregate, have~~ a ~~substantial~~price ~~negative~~greater ~~impact~~than onyou ~~our financial condition and results of operations~~paid.

12We do not plan to declare dividends on shares of our new common stock in the foreseeable future. In addition, the DIP Facility generally prohibits us from paying such dividends. We currently intend to retain any future earnings to finance the operation of our business and meet our debt obligations. As a result, you may only receive a return on your investment in our common stock if the market price of our common stock increases.

The outstanding indebtedness under our Amended Credit Agreement and the DIP Facility is, and any Exit Facility or other future debt arrangements would most likely be, secured by substantially all of our assets and guaranteed by our two domestic operating subsidiaries, subject to certain exceptions. We may be unable to repay or refinance our debt as it becomes due, whether at maturity or as a result of acceleration.

The outstanding indebtedness under our Amended Credit Agreement is, subject to limited exceptions, secured by a first-priority lien on a substantial amount of our assets, including (i) a pledge of all accounts receivable and inventory, (ii) cash in certain accounts, (iii) domestic distribution assets residing on owned real property, (iv) our Marshfield, Wisconsin and Toomsboro, Georgia plant facilities and equipment, and (v) certain real property interests in mines and minerals, and the outstanding indebtedness under the DIP Facility is secured by all of our assets, subject to limited exceptions. We are in default under the Amended Credit Agreement as a result of filing the Chapter 11 Cases, but the Supporting Lenders are not able to pursue remedies thereunder as a result of the automatic stay under the Bankruptcy Code. In the event of a default under the DIP Facility, the DIP Lenders may, subject to the order of the Bankruptcy Court approving the DIP Facility, (1) elect to declare all outstanding borrowings made under the DIP Facility and the guaranties of the two operating subsidiaries, together with accrued interest and other fees, to be immediately due and payable; (2) exercise their set-off rights; and/or (3) enforce and foreclose on their security interest and liquidate some or all of such pledged assets. Any of these actions would, individually or in the aggregate, have a substantial negative impact on our financial condition and results of operations.

We may not be able to repay our debt as it comes due, or to refinance our debt on a timely basis or on terms acceptable to us and within the limitations contained in the DIP Facility or any Exit Facility or other post-emergence debt arrangement when payment obligations are no longer automatically stayed under the provisions of the Bankruptcy Code. Failure to repay or to timely refinance any portion of our debt could result in a default under the terms of all our debt instruments and the acceleration of all indebtedness outstanding.

We rely upon, and receive a significant percentage of our revenues from, a limited number of key customers and end users.

During ~~2018~~2019, our key customers included several of the largest participants in the worldwide petroleum pressure pumping industry, as well as certain operators of natural gas and oil wells. ~~Two~~One of these customers ~~each~~ accounted for more than 10% of our ~~2018~~2019 revenues. ~~However,~~The ~~the~~ end users of our products are numerous operators of natural gas and oil wells that hire pressure pumping service companies to hydraulically fracture wells. During ~~2018~~2019, a majority of our ceramic proppant sales were directed to a concentrated number of end users. We generally supply our domestic pumping service customers with products on a just-in-time basis, with transactions governed by individual purchase orders and/or a master supply agreement. Because of their purchasing power, our key customers may have greater bargaining leverage than us with respect to the negotiation of prices and other terms of the sale in their supply contracts with us, which in turn, could adversely affect our profit margins associated with those contracts. Disparities in bargaining leverage, when combined with the Company’s desire to maintain long-term relationships with key customers, could limit our practical ability to assert certain terms of our supply agreements with them. Continuing sales of our products depend on our direct customers and the end user well operators being satisfied with product quality, pricing, availability, and delivery performance. While we believe we have satisfactory relations with our customers and our end users, a material decline in the level of sales to any one of our major customers or loss of a key end user due to unsatisfactory product performance, pricing, delivery delays or any other reason could have a material adverse effect on our results of operations and financial condition.

The operations of our customers, and thus the results of our operations, are subject to a number of operational risks, interruptions and seasonal trends.

As hydraulic fracturing jobs have increased in size and intensity, common issues such as weather, equipment delays or changes in the location and types of oil and natural gas plays can result in increased variability in proppant sales volumes. Our business operations and those of our customers involve a high degree of operational risk. Natural disasters, adverse weather conditions, collisions and operator error could cause personal injury or loss of life, severe damage to and destruction of property, equipment and the environment, and suspension of operations. Our customers perform work that is subject to unexpected or arbitrary interruption or termination. The occurrence of any of these events could result in work stoppage, loss of revenue, casualty loss, increased costs and significant liability to third parties. With the increase in resource plays in the northern and eastern United States, as well as our operations in Marshfield, Wisconsin, our results of operations are increasingly exposed to seasonal variations and inclement weather. Operations in certain regions involve more seasonal risk in the winter months, and work is hindered during other inclement weather events. This variability makes it more difficult to predict sales and can result in greater fluctuations to our quarterly financial results. These quarterly fluctuations could result in operating results that are below the expectations of public market analysts and investors, and therefore may adversely affect the market price for our common stock.

This variability makes it more difficult to predict sales and can result in greater fluctuations to our quarterly financial results. These quarterly fluctuations could result in operating results that are below the expectations of public market analysts and investors, and therefore may adversely affect the market price for our common stock.

The ability of our customers to complete work, as well as our ability to mine sand from cold climate areas, could be affected during the winter months. Our revenue and profitability could decrease during these periods, as well as in other severe weather conditions, because work is either prevented or more costly to complete. If a substantial amount of production is interrupted, our cash flow and, in turn, our results of operations could be materially and adversely affected.

Any adverse developments at these plants, including a material disruption in production, an inability to supply the plant with raw materials at a competitive cost, or adverse developments due to catastrophic events, could have a material adverse effect on our financial condition and results of operations.

We provide environmental warranties on certain of our containment and spill prevention products.

AGPI’s tank liners, secondary containments and related products and services are designed to contain or avoid spills of hydrocarbons and other materials. If a release of these materials occurs, it could be harmful to the environment. Although we attempt to negotiate appropriate limitations of liability in the applicable terms of sale, some customers have required expanded warranties, indemnifications or other terms that could hold AGPI responsible in the event of a spill or release under particular circumstances. If AGPI is held responsible for a spill or release of materials from one of its customer’s facilities, it could have a material adverse effect on our results of operations and financial condition.

We rely upon intellectual property to protect our proprietary rights. Failure to protect our intellectual property rights may affect our competitive position, and protecting our rights or defending against third-party allegations of infringement may be costly.

The Company uses a significant amount of trade secrets, or “know-how,” and other proprietary information and technology in the conduct of its business. In some cases, we rely on trade secrets, trademarks or contractual restrictions to protect intellectual property rights that are not patented. The steps we take to protect the non-patented intellectual property may not be sufficient to protect it and any loss or diminishment of such intellectual property rights could negatively impact our competitive advantage. Additionally, our competitors could independently develop the same or similar technologies that are only protected by trade secret and thus do not prevent third parties from competing with us. Furthermore, even protected intellectual property rights can be infringed upon by third parties. Monitoring unauthorized use of Company intellectual property can be difficult and expensive, and adequate remedies may not be available.

Although the Company does not believe that it is infringing upon the intellectual property rights of others by using such proprietary information and technology, it is possible that such a claim might be asserted against the Company in the future. In the event any third party makes a claim against us for infringement of patents or other intellectual property rights of a third party, such claims, with or without merit, could be time-consuming and result in costly litigation. In addition, the Company could experience loss or cancellation of customer orders, experience product shipment delays, or be subject to significant liabilities to third parties. If our products or services were found to infringe on a third party’s proprietary rights, the Company could be required to enter into royalty or licensing agreements to continue selling its products or services. Royalty or licensing agreements, if required, may not be available on acceptable terms, if at all, which could seriously harm our business. Involvement in any patent dispute or other intellectual property dispute or action to protect trade secrets and expertise could have a material adverse effect on the Company’s business.

Significant increases in fuel prices for any extended periods of time will increase our operating expenses.

The price and supply of natural gas are unpredictable, and can fluctuate significantly based on international, political and economic circumstances, as well as other events outside of our control, such as changes in supply and demand due to weather conditions, actions by OPEC and other oil and gas producers, regional production patterns and environmental concerns. Natural gas is a significant component of our direct manufacturing costs and price escalations will likely increase our operating expenses and can have a negative impact on income from operations and cash flows. We operate in a competitive marketplace and may not be able to pass through all of the increased costs that could result from an increase in the cost of natural gas.

have a negative impact on income from operations and cash flows. We operate in a competitive marketplace and may not be able to pass through all of the increased costs that could result from an increase in the cost of natural gas.

Environmental compliance costs and liabilities could reduce our earnings and cash available for operations.

We are subject to increasingly stringent laws and regulations relating to environmental protection, including laws and regulations governing air emissions, water discharges and waste management. The technical requirements of complying with these environmental laws and regulations are becoming increasingly expensive and complex, and may affect the Company’s ability to expand its operations. Our ability to continue the expansion of our manufacturing capacity to meet market demand is contingent upon obtaining required environmental permits and compliance with their terms, which continue to be more restrictive and require longer lead times to obtain in anticipation of any efforts to expand and increase capacity. We incur, and expect to continue to incur, capital and operating costs to comply with environmental laws and regulations.

In addition, we use some hazardous substances and generate certain industrial wastes in our operations. Many of our current and former properties are, or have been, used for industrial purposes. Accordingly, we could become subject to potentially material liabilities relating to the investigation and cleanup of contaminated properties, and to claims alleging personal injury or property damage as the result of exposures to, or releases of, hazardous substances. These laws also may provide for “strict liability” for damages to natural resources or threats to public health and safety. Strict liability can render a party liable for environmental damage without regard to negligence or fault on the part of the party. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances.

Stricter enforcement of existing laws and regulations, new laws and regulations, the discovery of previously unknown contamination or the imposition of new or increased requirements could restrict our expansion efforts, require us to incur costs, or become the basis of new or increased liabilities. Any of these events could reduce our earnings and our cash available for operations.

Our international operations subject us to risks inherent in doing business on an international level that could adversely impact our results of operations.

International revenues accounted for approximately 1927% and 2119% of our total revenues in ~~2018~~2019 and ~~2017~~2018, respectively. We may not succeed in overcoming the risks that relate to or arise from operating in international markets. Risks inherent in doing business on an international level include, among others, the following:

•

economic and political instability (including as a result of the threat or occurrence of armed international conflict or terrorist attacks);

•

potential declines or increased volatility in oil and natural gas prices that would adversely affect our customers, the energy industry or our production costs;

•

changes in regulatory requirements, economic sanctions, tariffs, customs, duties and other trade barriers;

•

transportation delays and costs;

•

power supply shortages and shutdowns;

•

difficulties in staffing and managing foreign operations and other labor problems;

•

currency rate fluctuations, convertibility and repatriation;

•

taxation of our earnings and the earnings of our personnel;

•

potential expropriation of assets by foreign governments and

•

other risks relating to the administration of or changes in, or new interpretations of, the laws, regulations and policies of the jurisdictions in which we conduct our business.

Undetected defects in our fracture simulation software could adversely affect our business.

Despite extensive testing, our software could contain defects, bugs or performance problems. If any of these problems are not detected, the Company could be required to incur extensive development costs or costs related to product recalls or replacements. The existence of any defects, errors or failures in our software products may subject us to liability for damages, delay the development or release of new products and adversely affect market acceptance or perception of our software products or related services, any one of which could materially and adversely affect the Company’s business, results of operations and financial condition.

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 our new common stock.

The success of our business depends on achieving our strategic objectives, including the diversification of our product and service portfolio.

As we continue to expand our portfolio of product and service offerings to industrial and other new markets, we face certain risks associated with these new business strategies, including unknown regulatory changes and product acceptance by these new markets, that could affect our future financial results. In addition, lower than expected sales in these new markets could have a material adverse effect on our results from operations and financial condition.

Recent Developments

Reorganization, Chapter 11 Proceedings, and Going Concern

The Debtors filed the Chapter 11 Cases under the Bankruptcy Code on March 29, 2020.

Since the commencement of the Chapter 11 Cases, each of the Debtors has continued to operate its business as a “debtor-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. At the conclusion of the Chapter 11 Cases, we expect the Supporting Lenders to exchange certain claims against us that they hold for 100% of the equity interests in Reorganized CARBO and that our existing common stock will be cancelled.

The risks and uncertainties surrounding the Chapter 11 Cases, the defaults under our Credit Agreement, the depressed condition of the oil and natural gas industry and broader economic conditions raise substantial doubt as to our ability to continue as a going concern. Accordingly, the audit report issued by our independent registered public accounting firm on our financial statements as of and for the year ended December 31, 2019 contains an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which contemplate our continuation as a going concern. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern. For additional information concerning our bankruptcy proceedings under Chapter 11, see Note 1 to the Consolidated Financial Statements, “Item 1— Business—Recent Developments—Voluntary Reorganization Under Chapter 11 of the Bankruptcy Code” and “Item 1A—Risk Factors—Risks Relating to Our Chapter 11 Proceedings.”

COVID-19 Update

On March 13, 2020, the United States declared the COVID-19 pandemic a national emergency, and several states, including Texas and other states in which we operate, and municipalities have declared public health emergencies. Along with these declarations, there have been extraordinary and wide-ranging actions taken by international, federal, state and local public health and governmental authorities to contain and combat the outbreak and spread of COVID-19 in regions across the United States and the

world, including mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations. To the extent COVID-19 continues or worsens, governments may impose additional similar restrictions.

Due to a combination of geopolitical and COVID-19 pandemic related pressures on the global supply-demand balance for crude oil and related products, commodity prices have significantly declined in recent months, and oil and gas operators, including certain of our customers, have reduced development budgets and activity. Although the full impact of the decline in commodity prices and the COVID-19 pandemic on our business are currently unknown and continue to evolve as of the date of this report, we expect that demand for our products and services will be adversely affected and we may see ongoing operational interruptions, which would adversely affect our business and financial condition. The Company will continue to work with its customers and suppliers to ensure the protection of our collective workforces when and where they interact.

Executive Level Overview

CARBO Ceramics Inc. is a global technology company that provides products and services to the oil and gas, industrial, and environmental markets to enhance value for its clients.

The Company conducts its business within two operating segments: 1) Oilfield and Industrial Technologies and Services and 2) Environmental Technologies and Services.

Oilfield ceramic technology products, and base ceramic proppant ~~and frac sand proppant~~ are manufactured and sold to pressure pumping companies and oil and gas operators for use in the hydraulic fracturing of natural gas and oil wells. Hydraulic fracturing is the most widely used method of increasing production from oil and natural gas wells. The hydraulic fracturing process consists of pumping fluids down a natural gas or oil well at pressures sufficient to create fractures in the hydrocarbon-bearing rock formation. A granular material, called proppant, is suspended and transported in the fluid and fills the fracture, “propping” it open once high-pressure pumping stops. The proppant filled fracture creates a conductive channel through which the hydrocarbons can flow more freely from the formation to the well and then to the surface.

There are three primary types of proppant that can be utilized in the hydraulic fracturing process: sand, resin coated sand and ceramic. Sand is the least expensive proppant, resin-coated sand is more expensive and ceramic proppant is typically the most expensive. We believe the higher initial cost of ceramic proppant is justified by the fact that its use in certain well conditions typically results in an increase in the production rate of oil and natural gas, an increase in the total oil or natural gas that can be recovered from the well and, consequently, an increase in cash flow for the operators of the well. The increased production rates are primarily attributable to the higher strength and more uniform size and shape of ceramic proppant versus alternative materials. WeDuring ~~are~~the ~~one~~fourth quarter of ~~the~~2019, ~~world’s~~we ~~largest~~idled ~~suppliers~~all of ~~ceramic~~our ~~proppant~~sand operations, and we are currently evaluating alternatives for the sand business.

Through our wholly-owned subsidiary StrataGen, Inc., we promote increased production and EUR of oil and natural gas by selling a widely used fracture stimulation software under the brand FracPro, and providing fracture design and consulting services to oil and natural gas E&P companies under the brand StrataGen.

Our industrial ceramic technology products are manufactured and sold to industrial companies. These products are designed for use in various industrial technology applications, including but not limited to casting and milling.

We also produce industrial products at our manufacturing facilities for third parties under tolling arrangements. These products so far have been primarily used in industrial, or agricultural applications. ~~Contract manufacturing has led to increased revenue generation.~~ We continue to develop additional opportunities within the industrial, agricultural and oil and gas industries to grow revenue, and reduce our plant’s slowing and idling costs.

Our Environmental Technologies and Services segment is intended to protect operators’ assets, minimize environmental risks, and lower lease operating expense (“LOE”). AGPI, the only subsidiary of ours to operate in this segment, provides spill prevention, containment and countermeasure systems for the oil and gas industry. AGPI uses proprietary technology to make products designed ~~to enable its clients to extend the life of their storage assets, reduce the potential for hydrocarbon spills and provide containment of stored materials.~~

~~International revenues represented 19% and 21% of total revenues in 2018 and 2017, respectively.~~28

to enable its clients to extend the life of their storage assets, reduce the potential for hydrocarbon spills and provide containment of stored materials.

International revenues represented 27% and 19% of total revenues in 2019 and 2018, respectively.

Operating profit margin for our ceramic business is principally impacted by sales volume, product mix, sales price, distribution costs, manufacturing costs, including natural gas, and our production levels as a percentage of our capacity. The level of selling, general and administrative spending, as well as other operating expenses, can also impact operating profit margins.

As a result of the depressed commodity price we continued to experience in 2018, there has been a negative impact on industry activity levels which has in turn negatively impacted the demand for ceramic proppant, so we continue to focus on cash preservation and cost reduction strategies. See “Item 1 - Business” and “Item 1A - Risk Factors”.

Although most direct manufacturing expenses have been relatively stable or predictable over time, we have historically experienced volatility in the cost of natural gas used in the production of our products. In an effort to mitigate volatility in the cost of natural gas purchases and reduce exposure to short term spikes in the price of this commodity, we contracted in advance for portions of our future natural gas requirements. Due to the severe decline in industry activity beginning in early 2015, we significantly reduced production levels and consequently did not take delivery of all of the contracted natural gas quantities. As a result, we had accounted for the relevant contracts as derivative instruments. However, as of December 31, 2018, our last derivative contract expired and no future natural gas obligations existed.

General Business Conditions

The oilfield portion of our Oilfield and Industrial Technologies and Services segment is impacted by the number of natural gas and oil wells drilled in North America, and the need to hydraulically fracture these wells. Current demand for proppant is extremely dynamic. In addition to rig counts and commodity prices, the oilfield portion is also significantly affected by a host of other factors, including but not limited to (a) completion activity, which is not necessarily correlated with rig count, (b) customer preferences, (c) new product and technology adoption, (d) imports and competition, including the cost of competing products, (e) changes in the product mix of what we sell, (f) costs of developing our products and services and running our business, and (g) changes in our strategy and execution. In markets outside North America, sales of our products are also influenced by the overall level of drilling and hydraulic fracturing activity. Furthermore, because the decision to use ceramic proppant is based on comparing the higher initial costs to the future value derived from increased production and recovery rates, our business is influenced by the current and expected prices of natural gas and oil.

Beginning in late 2014, a severe decline in oil and continued decline in natural gas prices led to a significant decline in oil and natural gas industry drilling activities and capital spending. During 2018, however, the average price of West Texas Intermediate (“WTI”) crude oil rose 28% to $64.94 per barrel compared to $50.88 per barrel in 2017. The average North American rig count also rose 13% in 2018 to 1,222 rigs compared to 1,081 rigs in 2017. Despite these improvements, E&P operators continued to use lowest-cost completions, a trend that we expect to continue in 2019, as our customers remain under pressure to consider lower cost alternatives, notwithstanding the superior performance results of our products. These events, along with an oversupplied ceramic proppant market and depressed oil and natural gas prices, kept demand and average prices low for our proppants.

Beginning early in 2015, we implemented a number of initiatives to preserve cash and lower costs, including: (1) reducing workforce across our organization, (2) lowering our production output levels in order to align with lower demand, including through idling and mothballing of some of our production facilities (3) limiting capital expenditures and (4) eliminating dividends. As a result of operating some of our plants below their normal production capacity, we expensed $32.5 million of production overhead costs in excess of amounts that would have been allocated to each unit of production at normal production levels. We continue to rationalize headcount as needed.

Our Environmental Technologies and Services segment is also impacted by the global drilling and hydraulic fracturing activity, and has been negatively impacted by the significant decline in oil and natural gas industry drilling activities and capital spending.

On December 31, 2018, we received net proceeds of $22.1 million relating to the sale of our Millen, Georgia plant. After consideration of certain post-closing matters and retained liabilities associated with the sale, we expect net cash proceeds to approximate $15.7 million.

Throughout our history, base ceramic was our dominant source of revenue. In 2014, base ceramic represented approximately 80% of our total revenue. In 2018, it represented approximately 20%. The decline is representative of the pressure operating companies are under to produce at the lowest cost possible, often at the expense of long term productivity. In response, we are undergoing a strategic transformation to (1) diversify revenue streams, (2) return the Company to profitability by growing revenue and reducing costs, and (3) growing the business with minimal capital investments. Our transformation strategy has showed solid progress as we continue to grow industrial and technology revenues, as well as reduce costs.

Critical Accounting Policies

Our Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the U.S., which require us to make estimates and assumptions (see Note 1 to the Consolidated Financial Statements). We believe that, of our significant accounting policies, the following may involve a higher degree of judgment and complexity.

19The accompanying financial statements have been prepared assuming that we will continue as a going concern. The Debtors filed Chapter 11 Cases under the Bankruptcy Code on March 29, 2020. The risks and uncertainties surrounding the Chapter 11 Cases, the defaults under our Credit Agreement, the depressed condition of the oil and natural gas industry and broader economic conditions raise substantial doubt as to our ability to continue as a going concern. Accordingly, the audit report issued by our independent registered public accounting firm on our financial statements as of and for the year ended December 31, 2019 contains an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which contemplate our continuation as a going concern. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern. For additional information concerning our bankruptcy proceedings under Chapter 11, see Note 1 to the Consolidated Financial Statements.

Revenue is recognized when title passes to the customer (generally upon delivery of products) or at the time services are performed. We generate a significant portion of our revenues and corresponding accounts receivable from sales to the petroleum pressure pumping industry and end users. In addition, during 2019, we ~~generate~~generated a significant portion of our revenues and corresponding accounts receivable from sales to ~~two~~one major ~~customers~~customer, ~~both~~an ofexploration ~~which~~and ~~are~~production ~~in the petroleum pressure pumping industry~~company. AsHowever, as of December 31, ~~2018~~2019, ~~approximately~~less 26than 1% of the balance in trade accounts receivable was attributable to ~~those~~that ~~two~~customer, ~~customers~~as we recently mutually terminated the purchase agreement with that customer. We record an allowance for doubtful accounts based on our assessment of collectability risk and periodically evaluate the allowance based on a review of trade accounts receivable. Trade accounts receivable are periodically reviewed for collectability based on customers’ past credit history and current financial condition, and the allowance is adjusted, if necessary. If the economic downturn in the petroleum pressure pumping industry worsens or does not materially improve or, for some other reason, any of our primary customers were to experience significant adverse conditions, our estimates of the recoverability of accounts receivable could be reduced by a material amount and the allowance for doubtful accounts could be increased by a material amount. As of December 31, ~~2018~~2019, the allowance for doubtful accounts totaled $12.32 million.

We value inventory using the weighted average cost method. Assessing the ultimate realization of inventories requires judgments about future demand and market conditions. We regularly review inventories to determine if the carrying value of the inventory exceeds net realizable value and we record an adjustment to reduce the carrying value to net realizable value, as necessary. Future changes in demand and market conditions could cause us to be exposed to additional obsolescence or slow moving inventory. If actual market conditions are less favorable than those projected by management, lower of cost or net realizable value adjustments may be required. During the year ended December 31, 2019, the Company recognized a $4.3 million lower of cost or net realizable value adjustment in cost of sales. There were no lower of cost or net realizable value inventory adjustments for the ~~years~~year ended December 31, 2018 ~~and 2017~~.

Income taxes are provided for in accordance with ASC Topic 740, “Income Taxes”. This standard takes into account the differences between financial statement treatment and tax treatment of certain transactions. Deferred tax assets (“DTAs”) and liabilities (“DTLs”) are recognized for the future tax consequences attributable to differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates is recognized as income or expense in the period that includes the enactment date. This calculation requires us to make certain estimates about our future operations. Changes in state, federal and foreign tax laws, as well as changes in the Company’s financial condition, could affect these estimates.

Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, provides the carrying value of DTAs should be reduced by the amount not expected to be realized. A company should reduce deferred tax assets by a valuation allowance if, based on the weight of all available evidence, it is no longer more likely than not that some portion or all of the deferred tax assets will be realized. The valuation allowance should be sufficient to reduce the deferred tax asset to the amount that is more likely than not to be realized. ASC 740 requires all available evidence, both positive and negative, be considered to determine whether a valuation allowance for deferred tax assets is needed in the financial statements. Additionally there can be statutory limitations and losses also assessed on the deferred tax assets should certain conditions arise.

We believe it is more likely than not that a portion of our deferred tax assets will not be realized in the future. Accordingly, we have a $72143.4 million valuation allowance against our deferred tax assets. Our assessment of the realizability of our deferred tax assets is based on the weight of all available evidence, both positive and negative, including future reversals of deferred tax liabilities. Income tax ~~expense~~benefit was $02.92 million, or 10.27% of pretax loss, for the year ending December 31, ~~2018~~2019 compared to income tax ~~benefit~~expense of $2.0.9 million, or 01.82% of pretax loss, for the same period in ~~2017~~2018.

In December 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted. The Tax Legislation significantly revises the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. In accordance with the Tax Legislation, we recorded $28.2 million as additional income tax expense in the fourth quarter of 2017 related to the re-measurement of deferred tax assets and liabilities. Additionally, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. December 22, 2018 marked the end of the measurement period for purposes of SAB 118. As such, we have completed the analysis based on legislative updates relating to the Tax Legislation. No material changes to the provisional amounts recorded as of December 31, 2017 were identified. We continue to evaluate the impacts of the newly enacted global intangible low-taxed income (“GILTI”) provisions, which subject our foreign earnings to a minimum level of tax.

part of deferred taxes or as a period cost are both acceptable methods. As of December 31, 2018, we have not recognized foreign earnings subject to GILTI. An accounting policy will be elected in the first period in which the GILTI provision becomes applicable to us.

Long-lived assets, which include net property, plant and equipment, goodwill, intangibles and other long-term assets, comprise a significant amount of the Company’s total assets. The Company makes judgments and estimates in conjunction with the carrying values of these assets, including amounts to be capitalized, depreciation and amortization methods and useful lives. Additionally, the carrying values of these assets are periodically reviewed for impairment or whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount is not recoverable. This requires the Company to make long-term forecasts of its future revenues and costs related to the assets subject to review. These forecasts require assumptions about demand for the Company’s products and services, future market conditions and technological developments. Significant and unanticipated changes to these assumptions could require a provision for impairment in a future period.

AsDue ato ~~result~~worsening market conditions and outlook and the loss of a key customer during the ~~sale~~fourth quarter of 2019, we evaluated essentially all of our ~~Millen~~long-lived ~~facility~~assets for ~~less~~possible ~~than~~impairment ~~the~~and ~~carrying~~in ~~value~~doing ofso ~~each~~recognized ofan impairment charge totaling $169.9 million primarily related to (1) our Toomsboro, Georgia ~~and~~manufacturing plant, (2) our technology assets, including our Eufaula, Alabama ~~facilities~~and ~~combined~~New ~~with~~Iberia, ~~the~~Louisiana ~~continued~~manufacturing ~~lowered~~plants, ~~demand~~(3) ~~for~~ our ~~base~~sand ~~ceramic~~assets, ~~proppants~~including our Marshfield, weWisconsin ~~evaluated~~facility ~~those~~and ~~long-lived~~(4) various general corporate assets ~~for~~primarily ~~possible~~related ~~impairment~~to distribution centers we no longer intend to utilize in our business.

The total amount of right of use asset impairments recorded during the fourth quarter of 2019 was ~~required~~approximately $35.2 million.

In addition, the Company identified indicators of impairment relating to our PicOnyx investment, and as a result recorded an impairment of $4.1 million during the fourth quarter of 2019.

The Company evaluated goodwill during the fourth quarter of 2019. The Company has been marketing for sale all or a portion of the Company to various parties. As a result of this marketing effort and various indications of interest, the Company estimated that the fair value of StrataGen, Inc. was less than the carrying value of identifiable assets, and as a result a $3.5 million impairment was recorded to goodwill.

As of September 30, 2019, the Company determined that the carrying amount of the assets located at one of its proppant distribution centers would not be recoverable as efforts to lease or sell the assets have not been successful due to its location. These assets are located on leased land. The land lease was renegotiated during the third quarter of 2019 to reduce our monthly cost, as well as to revise the lease term to end in December 2020. The Company does not expect to exercise the company renewal options. At the expiration of the lease term in December 2020, any remaining assets would become the property of the lessor. These distribution center assets were previously considered a general corporate asset that was evaluated for impairment in aggregate with other long-lived assets because it was built to distribute various products manufactured from multiple asset groups and was not built to service any one single asset group. When the Company made the decision to abandon the facility, we then evaluated these distribution center assets separately as opposed to aggregated with other long-lived assets. When the Company built this distribution center several years ago, it was originally intended to primarily distribute ceramic proppant in the Permian Basin. Since then, the market for ceramic proppant in that region deteriorated with the majority of operators instead using inexpensive sand proppants. Given that the Company was no longer able to utilize this distribution center for ceramic proppant, the Company leased the facility in 2017 to a third party who used it for transloading sand in the region. During 2019, the market in the Permian Basin further shifted to very inexpensive in-basin

sand that does not require the use of a distribution center, as the sand is trucked directly to the wellsite from the mine. Further, during the third quarter of 2019, the lease with the third party expired and was not renewed. Given these developments and the expectation for them to continue indefinitely, there is no business need for these distribution center assets in the region. As we do not expect to renew the lease and efforts to locate a buyer have not been successful, the Company concluded to abandon the assets and has recorded an impairment of $8.1 million, recorded within other operating expenses on the statement of operations. The Company wrote the assets down to a salvage value of $0 given that no interested buyers were identified while marketing the assets at scrap values. In addition, during the third quarter of 2019, the Company abandoned and wrote off $0.5 million in inventory at this leased facility that we do not anticipate selling and expect to leave on site at the end of the lease term as it would be too costly to relocate, recorded within other operating expenses on the statement of operations. In addition, several right of use operating lease assets were abandoned during the third quarter of 2019, and as a result we recorded an impairment to the right of use assets totaling $3.9 million.

During the fourth quarter of 2019, we evaluated the carrying value of inventories and concluded that for certain inventory, the net realizable value had fallen below its carrying value, and as a result, we recorded a $4.3 million inventory adjustment within cost of sales on the consolidated statements of operations.

Low production levels triggered the component of our inventory accounting policy relating to operating at production levels below normal capacity. To determine the amount of production costs that we expense during each period, the Company allocates fixed production overheads to the costs of conversion based on the normal capacity of each production facility, generally considered to be 65% of a facility's stated capacity or higher.

When a production facility operates at normal capacity, all of its fixed production overheads are allocated to costs of conversion of each product manufactured, based on the actual level of production. This determination is made facility-by-facility on a monthly basis in order to calculate the initial measurement value to recognize as cost of goods produced in a month by a given facility.

When a facility's total production in a month drops below 65% of its normal capacity, it is considered to be operating at an abnormally low production level. In such cases, each unit of production receives an allocation of fixed overheads in the amount that would have been allocated at the lower-end of normal capacity. The remaining unallocated excess fixed overhead cost for the facility is recognized as expense in the period and classified as Cost of Sales.

Materials are the only variable component of production. Plant labor and all other overhead costs incurred in the production of the Company's products are either semi-fixed or fixed in nature, therefore all are included in the monthly evaluation of costs allocable to costs of conversion at normal capacity.

The Company maintains a rate for each production facility that represents the maximum fixed production overhead cost per unit of production allocable to costs of conversion. The rates are based on an analysis of a recent historical period considered representative of a normal operating environment in which the facility operated at normal capacity. The maximum rate is calculated by recasting the fixed production overhead cost per unit of production on a pro forma basis as if the facility had operated at the lower-end threshold of its range of normal capacity, generally 65% of stated capacity. The current rates are based on 2014 as the representative year. Implied in this method is the assumption that 2014 production costs relative to sales prices yield a normal profit margin. A significant, permanent deterioration in the average selling prices of the Company’s products could result in a significant lowering of the rates, thereby increasing the periodic charge. The most recent period in which normal capacity was achieved was the year-ended December 31, 2014.

Results of Operations

Net Loss		$	(75304,~~433~~201	)			70(303	)%		$	(~~253~~75,~~116~~433	)

21For the year ended December 31, 2019, we reported net loss of $304.2 million, which was 303% worse compared to the $75.4 million net loss reported in the previous year. This increase in net loss was primarily due to decreases in sales of technology products and services, base ceramic and sand proppants, and environmental technologies and services. In addition, during the year ended December 31, 2019, we recorded impairments of various long-lived assets totaling approximately $225 million, as well as lower of cost or net realizable value inventory adjustments of $4.3 million.

For the year ended December 31, 2018, we reported net loss of $75.4 million, which was a 70% improvement compared to the $253.1 million net loss reported in the previous year. Excluding the impact of income taxes, other operating (income) expense, and the loss on the sale of our Russian proppant business and Millen plant, net loss in 2018 improved by $30.4 million, or 30%, primarily due to an increase in sales of technology and industrial products and services and an increase in sales of Environmental Technologies and Services. In addition, slowing and idling costs were reduced by $8.2 million, which was partially offset by an increase of $1.3 million in severance and other charges as compared to 2017.

Individual components of financial results by reportable operating segment are discussed below.

Outlook

We are very pleased with the profitable growth in our Industrial and Environmental business sectors. The growth of these two sectors should result in a balanced portfolio that is less susceptible to swings in oil and gas commodity prices. We are also pleased with the oilfield technology products and services profitable growth, and expect to retain our leadership position in those products and services.

In the Oilfield sector, E&P operators’ focus on free cash flow, coupled with recent oil price volatility, creates a less than certain environment with regard to drilling and completion spend in 2019. Some industry analysts are predicting 2019 drilling and completion spend to be down high single digits on a percentage basis compared to 2018. However, we are seeing positive signs internationally that should bode well for our oilfield sector products.

The Industrial sectors provide a large, multi-year growth opportunity for CARBO. In the mining sector, more companies have started increasing their operating and capital spend, which supports our CARBOGRIND product growth. In the foundry industry, the value our products bring to improve our client’s end-product quality, along with the need to comply with OSHA Permissible Exposure Limits (PEL) silicosis regulations, supports our ACCUCAST product growth. In both these sectors, and in numerous other Industrial sectors, our ceramic technology products are seeing market share growth.

The Environmental sector continues to see growth, as companies in various industry sectors continue to be more environmentally conscious. This provides us with a multi-year growth opportunity, in which we will put a strong focus on growing at high rates in Industrial sectors.

We anticipate our 2019 consolidated revenue to be similar to 2018.

We expect continued strong growth for our international ceramic technology sales in 2019. Demand for our technology continues to increase in South America, as well as in Europe, Africa and the Middle East. In North America, the opportunity set for our ceramic technology sales remains strong, with KRYPTOSPHERE HD projects currently weighted more to the second half of the year.

On the fracture technology design and analysis front, demand for our StrataGen consultants, and our FracPro software, is expected to remain strong as our clients utilize these offerings to optimize their completion designs and return economics.

At this time, we anticipate base ceramic sales and frac sand sales to decrease single digits on a percentage basis, similar to the lower industry expectations for drilling and completion spend. For base ceramics, we continue to drive business model changes towards production on demand, along with upfront cash commitments. For frac sand, a high percentage of our sand capacity is under contract, from which we are also benefiting from the use of our rail cars and distribution center.

We expect strong double digit growth in industrial revenues in 2019 through continued growth of our ceramic media in both the grinding and foundry markets. Our industrial ceramic client list is expanding globally, and should lead to improved market share for our technology products. We are also developing new markets while expanding the existing markets we sell into through a broader range of technology product offerings.

Our PicOnyx Inc. investment is off to a strong start. We recently initiated the first phase of the manufacturing process. M-Tone pigment is expected to be in the market during the first half of 2019, and we expect production to ramp up over the course of the year.

CARBO has world class manufacturing expertise. This manufacturing expertise is used to develop solutions for our clients. There are a number of contract manufacturing opportunities in the queue. We expect to grow both in revenue and by expanding the types of products we produce. The benefit of expanding our products has the potential to be significant as these projects take idled assets and turn them from cash consumers to cash producers.

Growth in product sales and expanding our reach outside the oilfield should result in revenue growth for ASSETGUARD in 2019. We are increasing resources specifically dedicated to growing industrial and other end market sales. ASSETGUARD continues to lead the industry in developing technology products to address the ongoing challenges of our clients.

Progress on our transformation strategy will continue in 2019 as we continue to focus on diversifying our revenue streams, maximizing profitability across the businesses, and maintaining healthy cash levels. We expect to be cash neutral in 2019, excluding planned debt repayments.

Liquidity and Capital Resources

At December 31, 2018, we had cash and cash equivalents and restricted cash of $83.3 million compared to cash and cash equivalents and restricted cash of $78.4 million at December 31, 2017. During the year ended December 31, 2018, we received net proceeds from asset sales of $27.5 million primarily related to the sale of our Millen plant, additional proceeds received from the sale of our Russian proppant business, as well as other asset sales. Net cash provided by financing activities was $1.0 million for the year ended December 31, 2018. Uses of cash included $21.6 million in operating activities and $2.0 million for capital expenditures. There were no major capital spending projects in 2018. Capital spending in 2018 primarily related to various plant maintenance as well as equipment purchases for the environmental business.Overview

~~The~~We ~~Company~~estimate anticipates that cash on hand will be sufficient to meet planned operating expenses, debt payments, and other cash needs for the next 12 months from the date of this Form 10-K. The Company’s view regarding sufficiency of cash and liquidity is primarily based on our ~~financial~~total ~~forecast~~capital ~~for~~expenditures the next twelve months, which is impacted by various assumptions regarding demand and sales prices for our products. Generally, we expect demand for our products and the sales prices to remain consistent in ~~2019 and the first quarter of~~ 2020 ~~compared~~will tobe ~~2018. We~~less ~~also~~than ~~expect to decrease our operating costs in 2019 and the first quarter of 2020 compared to 2018 while improving our cash position through continued balance sheet management~~$2. ~~Our~~0 ~~financial~~million ~~forecasts are based on estimates of customer demand, which is highly volatile in the current operating environment,~~ and we have no committed sales backlog with our customers. As a result, there is inherent uncertainty in our forecasts. In the event that we experience lower customer demand, lower prices for our products and services, or higher expenses than we have forecasted or if we underperform relative to our forecast, we could experience negative cash flows from operations, as has been the case in prior years, which would reduce our cash balances and liquidity.

Going Concern and Financial Reporting in Reorganization

As a result of our financial condition, the defaults under our Credit Agreement and the risks and uncertainties surrounding the Chapter 11 Cases, substantial doubt exists regarding to our ability to continue as a going concern. Accordingly, the audit report issued by our independent registered public accounting firm on our financial statements as of and for the year ended December 31, 2019 contains an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, which contemplate our continuation as a going concern. As such, the accompanying consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should the Company be unable to continue as a going concern.

Board of Directors, Committees of the Board of Directors and Meeting Attendance

The Board met eleven times and took action by unanimous written consent one time during the last fiscal year. Each Director attended at least 75 percent of all meetings of the Board and the Committees of which such Director is a member. Although there is no formal policy as to Director attendance at the Annual Meeting, all Directors attended the 2019 Annual Meeting.

The primary function of the Board is oversight, which includes among other matters, oversight of the principal risk exposures of the Company. To assist the Board in this role, the Audit Committee periodically requests the Company’s internal auditor to conduct a review of enterprise risks associated with the Company. The internal audit firm reports its findings and assessments to the Audit Committee, which then reports the findings to the Board as a whole.

The Board has an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee, each of which is currently comprised of five members. Each of these Committees has a charter, each of which is available free of charge on the Company’s website at www.carboceramics.com (together with the Company’s Corporate Governance Guidelines) or by writing to the Company at: CARBO Ceramics Inc., c/o Corporate Secretary, 575 N. Dairy Ashford, Suite 300, Houston, Texas 77079. The Board votes annually on the membership and chairmanship of all Committees.

Each Director elected to the Board will hold office until the next Annual Meeting or until his or her successor has been elected and qualified.

Audit Committee. The Audit Committee currently consists of Sigmund L. Cornelius (Chairman), Chad C. Deaton, H. E. Lentz, Jr., Randy L. Limbacher and Carla S. Mashinski. The Committee met eight times during the last fiscal year. The Board has determined that all of the members of the Audit Committee are independent within the meaning of the applicable rules of the SEC and the listing standards of the NYSE. The Board has also determined that Sigmund L. Cornelius and Carla S. Mashinski meet the requirements for being an “audit committee financial expert,” as that term is defined by applicable SEC and NYSE rules. The Audit Committee appoints and retains the Company’s independent registered public accounting firm, approves the fee arrangement and scope of the audit, reviews the financial statements and the independent registered public accounting firm’s report, considers comments made by the independent registered public accounting firm with respect to the Company’s internal control structure and reviews internal accounting procedures and controls with the Company’s financial and accounting staff. The Audit Committee also conducts the review of the non-audit services provided by the independent registered public accounting firm to determine their compatibility with its independence. The Audit Committee reviews the independent registered public accounting firm’s performance, qualification and quality control procedures and establishes policies for: (i) the pre-approval of audit and permitted non-audit services by the independent registered public accounting firm; (ii) the hiring of former employees of the independent registered public accounting firm; and (iii) the submission and confidential treatment of concerns from employees or others about accounting, internal controls, auditing or other matters.

The Audit Committee reviews with management the Company’s disclosure controls and procedures and internal control over financial reporting and the processes supporting the certifications of the Chief Executive Officer and Chief Financial Officer. It also reviews with management and the Company’s independent registered public accounting firm the Company’s critical accounting policies. The Audit Committee reviews the Company’s annual and quarterly SEC filings and other related Company disclosures. The Audit Committee reviews the Company’s compliance with the Code of Business Conduct and Ethics as well as other legal and regulatory matters. In performing these duties, the Audit Committee has full authority to: (i) investigate any matter brought to its attention with full access to all books, records, facilities and personnel of the Company; (ii) retain outside legal, accounting or other consultants to advise the Committee; and (iii) request any officer or employee of the Company, the Company’s in-house or outside counsel, internal audit service providers or independent registered public accounting firm to attend a meeting of the Committee or to meet with any members of, or consultants to, the Committee.

Compensation Committee. The Compensation Committee currently consists of Randy L. Limbacher (Chairman), Sigmund L. Cornelius, Chad C. Deaton, H. E. Lentz, Jr. and Carla S. Mashinski. The Committee met three times during the last fiscal year. The Board has determined that all of the members of the Compensation Committee are independent within the meaning of the listing standards of the NYSE. The Compensation Committee (i) establishes policies relating to the compensation of the non-employee Directors, officers and key management employees of the Company; (ii) reviews and approves the compensation of the non-employee Directors, officers and the President and Chief Executive Officer; (iii) reviews payment estimates with respect to cash incentive compensation awards for non-officer employees; (iv) oversees the administration of the Company’s equity compensation plans; and (v) reviews and approves periodically, but no less than annually, the Company’s compensation goals and objectives with respect to its officers, including oversight of the risks associated with the Company’s compensation programs. The Compensation Committee also evaluates and approves post-service arrangements with management and establishes and reviews periodically the Company’s perquisite policies for management and Directors.

In performing its duties, the Compensation Committee has ultimate authority and responsibility to engage and terminate any compensation consultant, legal counsel or other adviser (together “advisers”) to assist in determining appropriate compensation levels for the Chief Executive Officer or any other member of the Company’s management and to approve the terms of any such engagement and the fees of any such adviser. For 2019, Frederic W. Cook & Co., Inc. (“FW Cook”) was engaged by the Committee to provide compensation consulting services in connection with the Company’s annual the review of executive compensation. FW Cook did not provide any other services to the Company in 2019. In 2019, the Company also engaged Longnecker & Associates (“Longnecker”) to provide specific compensation consulting services for the design and development of our Key Employee Retention Program. Longnecker did not provide any other services to the Company in 2019. In addition, the Committee has full access to any relevant records of the Company and may also request that any officer or other employee of the Company (including the Company’s senior compensation or human resources executives), the Company’s in-house or outside counsel, or any other person meet with any members of, or consultant to, the Committee. In addition to information provided by outside compensation consultants, the officers of the Company may also collect peer group compensation data for review by the Committee.

The Committee sets the compensation policy for the Company as a whole and specifically decides all compensation matters related to the officers of the Company. The Committee has delegated to its Chairman the ability to grant interim equity awards to non-officer employees of the Company under the stockholder-approved equity plans of the Company in an amount not to exceed $100,000 of Common Stock per employee award, with such awards to be reported to the full Committee at its next meeting.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee currently consists of H. E. Lentz, Jr. (Chairman), Sigmund L. Cornelius, Chad C. Deaton, Randy L. Limbacher, and Carla S. Mashinski. The Committee met five times during the last fiscal year. The Board has determined that all of the members of the Nominating and Corporate Governance Committee are independent within the meaning of

the listing standards of the NYSE. The Nominating and Corporate Governance Committee establishes the Company’s corporate governance principles and guidelines. These principles and guidelines address, among other matters, the size, composition and responsibilities of the Board and its Committees, including their oversight of management. The Committee also advises the Board with respect to the charter, structure and operation of each Committee of the Board. The Nominating and Corporate Governance Committee oversees the evaluation of the Board and officers of the Company and reviews and periodically reports to the Board on matters concerning Company succession planning. The Committee has full access to any relevant records of the Company and may retain outside consultants to advise it. The Committee has the ultimate authority and responsibility to engage or terminate any outside consultant to identify Director candidate(s) and to approve the terms and fees of such engagement of any such consultant. The Committee may also request that any officer or other employee of the Company, the Company’s outside counsel, or any other person meet with any members of, or consultants to, the Committee.

The Company’s Board has charged the Nominating and Corporate Governance Committee with identifying individuals qualified to become members of the Board and recommending Director nominees for each Annual Meeting, including the recommendation of nominees to fill any vacancies on the Board. The Nominating and Corporate Governance Committee considers Director candidates suggested by its members, other Directors, officers and stockholders. Stockholders desiring to make such recommendations should timely submit the candidate’s name, together with biographical information and the candidate’s written consent to be nominated and, if elected, to serve to: Chairman, Nominating and Corporate Governance Committee of the Board of Directors of CARBO Ceramics Inc., 575 N. Dairy Ashford, Suite 300, Houston, Texas 77079. To assist it in identifying Director candidates, the Committee is also authorized to retain, at the expense of the Company, third party search firms and legal, accounting, or other advisors, including for purposes of performing background reviews of potential candidates. The Committee provides guidance to search firms it retains about the particular qualifications the Board is then seeking.

All Director candidates, including those recommended by stockholders, are evaluated on the same basis. Candidates are selected for their character, judgment, business experience and specific areas of expertise, among other relevant considerations, such as the requirements of applicable law and listing standards (including independence standards) and diversity of membership. The Company’s Corporate Governance Guidelines require the Nominating and Governance Committee to consider all aspects of each candidate’s qualifications and skills with a view to creating a Board with a diversity of experience and perspectives, including diversity with respect to race, gender, geography, and areas of expertise. Accordingly, the Nominating and Governance Committee must consider (and will ask any search firm that it engages to provide) a slate of diverse candidates including, but not limited to, women and minorities. The Board recognizes the importance of soliciting new candidates for membership on the Board and that the needs of the Boards, in terms of the relative experience and other qualifications of candidates, may change over time. In determining the needs of the Board and the Company, the Nominating and Corporate Governance Committee considers the qualifications of sitting Directors and consults with the Board, the Chief Executive Officer and certain other officers and, where appropriate, external advisors. All Directors are expected to exemplify the highest standards of personal and professional integrity and to assume the responsibility of challenging management through their active and constructive participation and questioning in meetings of the Board and its various Committees, as well as in less formal contacts with management. Director candidates, other than sitting Directors, are interviewed at the direction of the Committee, which may include (at the Committee’s direction) interviews by the Chairman of the Board, other Directors, the Chief Executive Officer and certain other officers, and the results of those interviews are considered by the Committee in its deliberations.

The members of the Nominating and Corporate Governance Committee constitute all of the non-management Directors on the Board. As the Chairman of the Nominating and Corporate Governance Committee, H. E. Lentz, Jr. serves as the presiding Director for non-management executive sessions of these Directors.

Code of Business Conduct and Ethics

The Company has adopted a Code of Business Conduct and Ethics that applies to its Directors and employees, including its Chief Executive Officer, Chief Financial Officer and Controller. The Code of Business Conduct and Ethics, including future amendments, is available free of charge on the Company’s website at www.carboceramics.com or by writing to the Company at: CARBO Ceramics Inc., c/o General Counsel, 575 N. Dairy Ashford, Suite 300, Houston, Texas 77079. The Company will also post on its website any amendment to or waiver under the Code of Business Conduct and Ethics granted to any of its Directors or executive officers. No such waivers were requested or granted in 2019.

Report of the Audit Committee

The Audit Committee met eight times during 2019. The Audit Committee reviewed with management and the independent registered public accounting firm the interim financial information included in the March 31, June 30 and September 30, 2019 Quarterly Reports on Form 10-Q prior to their filing with the SEC. In addition, the Audit Committee reviewed all earnings releases with management and the Company’s independent registered public accounting firm prior to their release.

Consistent with the applicable requirements of the Public Company Accounting Oversight Board, the Company’s independent registered public accounting firm provided the Audit Committee a written statement describing all the relationships between it and the Company that might bear on its independence. The Audit Committee also discussed and reviewed with the Company’s independent registered public accounting firm all communications required by generally accepted auditing standards, including those described in Statement on Auditing Standards No. 1301 (Communications with Audit Committees), which supersedes Statement on Auditing Standards No. 61.

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviews and discusses with management the audited financial statements in the Company’s Annual Report on Form 10-K, including a discussion of the acceptability and quality of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The Audit Committee reviewed with the Company’s independent registered public accounting firm, which is responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the acceptability and quality of the Company’s accounting principles and such other matters appropriate for discussion with the Audit Committee under generally accepted auditing standards. In addition, the Audit Committee has discussed with the independent registered public accounting firm its independence from management and the Company and considered the compatibility of non-audit services with its independence.

The Audit Committee discussed with the Company’s independent registered public accounting firm the overall scope and plans for its audit. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of its examinations, its evaluations of the Company’s internal controls and the overall quality of the Company’s financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2019, for filing with the SEC. The Audit Committee also approved, subject to stockholders’ ratification, the selection of the Company’s independent registered public accounting firm.

(3)	Mr. Wilks was appointed to the Board on June 20, 2019. Mr. Wilks resigned from the Board on November 13, 2019.

(4)	Ms. Mashinski was appointed to the Board on January 22, 2019.

Cash Fees. Directors who are not employees of the Company are paid a quarterly cash retainer of $10,000 plus $2,000 for each meeting of the Board that they attend, all paid on a quarterly basis. Non-employee Directors also receive $1,000 for each Committee meeting that they attend that does not immediately precede or follow a meeting of the Board, also paid on a quarterly basis. Effective July 1, 2016, the Directors voluntarily reduced their quarterly cash retainers to $8,000. In addition to their compensation as Directors, the Chairmen of the Audit and Compensation Committees each receive $10,000 annually as compensation for their service as Chairmen of these Committees. The Chairman of the Nominating and Corporate Governance Committee does not currently receive a separate payment for service as Chairman of this Committee. In addition to his compensation as a Director, the Lead Independent Director receives $15,000 annually, paid quarterly in equal installments. All Directors are reimbursed for out-of-pocket expenses incurred by them in attending meetings of the Board and its Committees and otherwise in performing their duties.

Equity Awards. Each non-employee Director who is serving in such capacity on the first business day after each Annual Meeting of Stockholders receives an annual grant of Common Stock with a market value of $100,000 as of such date (each, an “Annual Director Stock Grant”). However, in consideration of numerous cost reduction efforts being undertaken by the Company, beginning in March 2016 the Board voluntarily reduced the value of the Annual Director Stock Grant from $100,000 to $80,000 for 2016, 2017 and 2018. Mr. Morris waived his 2016, 2017 and 2018 Annual Director Stock Grants altogether. In 2018, each non-employee Director (other than Messrs. Rubin and Morris) received 7,498 shares of Common Stock as an Annual Director Stock Grant. In 2019, because of the decrease in value of Common Stock, the Annual Director Grant was limited to 7,500 shares.

Stock Ownership Requirements. Each non-employee Director is required to hold a minimum amount of shares of Common Stock (including shares of restricted stock) equal to all shares received as Annual Director Stock Grants during their tenure as a Director. Each non-employee Director currently meets this requirement.

Kolstad Employment Agreement. In the event that Mr. Kolstad’s employment is terminated due to disability or death, Mr. Kolstad, or his estate, shall be entitled to receive (i) all earned but unpaid base salary, (ii) payment for all earned but unused vacation time, and (iii) reimbursement for business expenses incurred prior to the date of termination (together, the “Accrued Obligations”). He, or his estate, shall also receive a pro-rated bonus based on the bonus he would have received for the year in which his employment terminated had his employment continued. If the Company terminates Mr. Kolstad’s employment for Cause, he shall only be entitled to receive the Accrued Obligations. In the event the Company terminates Mr. Kolstad’s employment without Cause, he shall be entitled to receive (i) the Accrued Obligations, (ii) a pro-rated bonus based on the bonus he would have received for the year in which his employment terminated had his employment continued and (iii) contingent upon his execution of a general release of claims against the Company, an amount equal to two times his base salary. The Accrued Obligations, pro-rated bonus and a portion of the base salary payment would be paid in a lump sum, and the remaining portion of the base salary payment would be paid over an 18 month period. Notwithstanding the foregoing, in the event Mr. Kolstad’s employment is terminated by the Company without Cause or by him for Good Reason, and in either case, during the one-year period following a change in control of the Company, he shall be entitled to receive (i) the Accrued Obligations, (ii) a pro-rated bonus based on the bonus he received in the year prior to his termination of employment and (iii) an amount equal to two times his base salary. In this instance, the Accrued Obligations and a portion of the bonus and base salary payment would be paid in a lump sum, with the remaining portion of the bonus and base salary payment to be paid over an 18 month period.

In Mr. Kolstad’s employment agreement, “Cause” is defined as (i) any material violation by Mr. Kolstad of the agreement; (ii) any failure by Mr. Kolstad to substantially perform his duties thereunder; (iii) any act or omission involving dishonesty, fraud, willful misconduct or gross negligence on the part of Mr. Kolstad that is or may be materially injurious to the Company; and (iv) commission of any felony or other crime involving moral turpitude.

“Good Reason” is defined as, without Mr. Kolstad’s express written consent, the occurrence of any one or more of the following: (i) the assignment of Mr. Kolstad to duties materially inconsistent with his authorities, duties, responsibilities and status (including offices, titles and reporting requirements) as an officer of the Company, or a reduction or alteration in the nature or status of his authorities, duties or responsibilities from those in effect immediately prior to a change in control, including a failure to reelect him to, or a removal of him from, any office of the Company that he held immediately prior to a change in control; or (ii) the Company’s requiring Mr. Kolstad to be based at a location more than 50 miles from Houston, Texas, except for required travel on the Company’s business to an extent substantially consistent with his business obligations immediately prior to a change in control; or (iii) the Company materially breaches the agreement or any other written agreement with Mr. Kolstad; or (iv) a material reduction in his level of participation in any of the Company’s welfare benefit, retirement or other employee benefit plans, policies, practices or arrangements in which he participates as of the date of the change in control. The Company is entitled to written notice and a 30 day cure period for any event that may constitute Good Reason.

Mr. Kolstad is subject to a covenant not to compete for a period of two years following the termination of his employment with the Company. He is also subject to standard covenants not to solicit employees and not to solicit clients for a period of one year following a termination.

2019, 2014 Omnibus Plan and A&R 2014 Omnibus Plan. All named executive officers are participants in the Omnibus Plans and continue to hold unvested awards of restricted stock and cash-settled restricted stock units. Each restricted stock and cash-settled restricted stock unit award agreement under the Omnibus Plans specifies the consequences with respect to such award upon any termination of employment. The applicable award agreements for the unvested awards of restricted stock and cash-settled restricted stock units made under the Omnibus Plans provide that unvested awards shall immediately vest upon a change in control or a termination of employment resulting from death or disability and that, upon any other termination of employment, all unvested awards shall be automatically forfeited.

The applicable award agreements for the unvested long-term cash performance-based awards made under the Omnibus Plans provide that upon a change in control, the unvested awards shall vest and be settled as to the target value of the award on a pro rata basis as of the date of such event. Upon separation of service due to death or disability, the unvested awards shall vest and be settled as to the target value of the award as of the date of such event. Upon separation of service due to Retirement, the unvested awards shall vest as of the date of such separation from service and will then be settled at the time they would have been had there been no separation from service and in an amount based on actual performance. Upon termination of employment for cause, all outstanding awards, whether vested or unvested, shall terminate automatically and be forfeited. For awards made prior to January 2019, upon termination of employment without cause, the unvested awards shall vest and be settled as to a portion of the award based on Relative Total Stockholder Return and New Technology Revenue achievement in performance years ending on or prior to the date of termination as of the date of such event. Beginning in January 2019, upon terminations of employment without cause, all unvested awards shall be automatically forfeited. In the event of any other termination of employment, as originally granted, all unvested awards shall be automatically forfeited.

Annual Performance-Based Cash Awards. From 2016 through 2019, all executive officers, including Mr. Kolstad, have been and are eligible for incentive payments under the annual performance-based cash awards pursuant to the Omnibus Plans. The annual performance-based cash awards provide that upon a change in control, the unvested awards shall vest and be settled as to the target value of the award on a pro rata basis as of the date of such event. Upon separation of service due to death or disability, the unvested awards shall vest and be settled as to the target value of the award as of the date of such event. Upon separation of service due to Retirement, the unvested awards shall vest as of the date of such separation from service and will then be settled at the time they would have been had there been no separation from service and in an amount based on actual performance. Upon termination of employment for cause, all outstanding awards, whether vested or unvested, shall terminate automatically and be forfeited. In the event of any other termination of employment, as originally granted, all unvested awards shall automatically be forfeited. In addition, Mr. Kolstad’s employment agreement and the CIC Agreements of the other named executive officers provide for a pro-rated bonus upon certain terminations of employment.

Change in Control Severance Agreements. In March 2012, the Board authorized the Company to enter into a CIC Agreement with Mr. Bautista. Mr. Conkle, pursuant to Board authorization, also entered into a CIC Agreement upon joining the Company in October 2012. Each CIC Agreement provides that in the event the executive’s employment is terminated by the Company without Cause or by him for Good Reason during the one-year period following a change in control of the Company, he shall be entitled to receive (i) accrued obligations (such as base salary earned through the date of termination and reimbursement for incurred expenses), (ii) a pro-rated bonus based on the bonus he received in the year prior to his termination of employment and (iii) an amount equal to two times his base salary. The accrued obligations and a portion of the bonus and base salary payment would be paid in a lump sum, with the remaining portion of the bonus and base salary payment to be paid over an 18 month period. The CIC Agreements are based on the change in control severance provisions utilized in Mr. Kolstad’s employment agreement, and contain definitions of “Cause” and “Good Reason” that are substantially the same as those that appear in such employment agreement. Neither Mr. Kolstad’s employment agreement nor the CIC Agreements provide for a “tax gross-up” reimbursement payment to the executive for taxes which they may owe as a result of receipt of any such payments.

(“Weaver”) as the Company’s independent registered public accounting firm for the Company’s fiscal year ending December 31, 2020, replacing Ernst & Young LLP (“EY”).

27The engagement of Weaver as the Company’s independent registered public accounting firm and the dismissal of EY from such role is expected to be effective on or about the date the Company filed this Annual Report on Form 10-K for the year ended December 31, 2019 with the Securities and Exchange Commission and upon Weaver’s formal acceptance of the engagement pending its receipt of the internal approvals necessary at that time.

Audit Fees. EY’s fees were approximately $709,630 in 2019 and $850,200 in 2018. In 2019, fees related primarily to the Company’s annual audit and review of interim financial statements, as well as work in conjunction with the Company’s long-lived asset and right of use asset impairment charges, the Company’s debt refinancing, and the Company’s investment in PicOnyx. In 2018, fees related primarily to the Company’s annual audit and review of interim financial statements, as well as work in conjunction with the Company’s adoption of ASC 842, Leases and work surrounding comfort letters related to the Company’s ATM program.

Audit-Related Fees. EY’s fees for audit-related services were $0 in 2019 and 2018.

Tax Fees. EY’s fees for tax services were $0 in 2019 and 2018.

All Other Fees. EY did not provide any other products and services in 2019 and 2018 and consequently there were no other fees.

Under the Audit Committee’s Pre-Approval Procedures for Audit and permitted Non-Audit Services, the Chairman of the Audit Committee is allowed to pre-approve audit and non-audit services if such services will commence prior to the next regularly scheduled meeting of the Audit Committee and where the cost of such services in the aggregate will not exceed $105,000. The Audit Committee is then informed of such pre-approval at its next meeting. For 2019 and 2018, there were no non-audit related services approved in this manner.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

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

Management, including our Chief Executive Officer and our Chief Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, ~~2018~~2019. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control–Integrated Framework (2013). Based on its assessment and those criteria, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, ~~2018~~2019.

The Company’s independent registered public accounting firm, Ernst & Young LLP, has issued an attestation report on the Company's internal control over financial reporting. That report is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CARBO Ceramics Inc.

Opinion on Internal Control over Financial Reporting

We have audited CARBO Ceramics Inc.’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CARBO Ceramics Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive loss, shareholders’ equity and cash flows for the years then ended, and the related notes and our report dated February 28, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed 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. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CARBO Ceramics Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CARBO Ceramics Inc. (the Company) as of December 31, ~~2018~~2019 and ~~2017~~2018, the related consolidated statements of operations, ~~comprehensive loss,~~ shareholders’' equity and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, ~~2018~~2019 and ~~2017~~2018, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

WeThe ~~also have audited, in accordance with the standards of the Public~~ Company ~~Accounting Oversight Board (United States) (PCAOB), the Company~~’s ~~internal~~Ability ~~control~~to ~~over~~Continue ~~financial reporting~~ as ofa ~~December~~Going 31, 2018, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 28, 2019 expressed an unqualified opinion thereon.Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, as a result of the Company’s financial condition, the defaults under the Credit Agreement and the risk of uncertainties surrounding the Chapter 11 Cases, substantial doubt exists regarding the Company’s ability to continue as a going concern. Management's evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Adoption of ASU No. 2016-02

As discussed in Note 1 to the consolidated financial statements, the Company changed its method of accounting for leases in 2019 due to the adoption of Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842), and the related amendments.

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. ~~Our~~The ~~audits~~Company ~~included~~is ~~performing~~not ~~procedures~~required to ~~assess~~have, ~~the~~nor ~~risks~~were ofwe ~~material~~engaged ~~misstatement of the financial statements, whether due~~ to ~~error or fraud~~perform, ~~and~~an ~~performing~~audit ~~procedures~~of ~~that~~its ~~respond~~internal tocontrol ~~those~~over ~~risks~~financial reporting. ~~Such~~As ~~procedures~~part ~~included~~of ~~examining,~~our onaudits awe ~~test~~are ~~basis,~~required ~~evidence~~to ~~regarding~~obtain ~~the~~an ~~amounts~~understanding ~~and~~of ~~disclosures~~internal incontrol ~~the~~over financial ~~statements.~~reporting ~~Our~~but ~~audits~~not ~~also~~for ~~included evaluating~~ the ~~accounting~~purpose ~~principles~~of ~~used~~expressing ~~and~~an ~~significant~~opinion ~~estimates~~on ~~made~~the byeffectiveness ~~management,~~of ~~as well as evaluating~~ the ~~overall~~Company's ~~presentation~~internal ofcontrol ~~the~~over financial ~~statements~~reporting.

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.

Description of Business

CARBO Ceramics Inc. (the “Company”) was formed in 1987 and is a global technology company that provides products and services to the oil and gas, industrial, and environmental markets to enhance value for its clients. The Company has production plants in: New Iberia, Louisiana; Eufaula, Alabama; McIntyre, Georgia; and Toomsboro, Georgia; and a sand processing facility in Marshfield, Wisconsin. The Company sold its Millen, Georgia production plant in December 2018. The Company sells its proppant products through pumping service companies that perform hydraulic fracturing for oil and gas companies. In addition, the Company sells ceramic media to industrial markets. Finished goods inventories are stored primarily at the plant sites and various ~~domestic and~~ international remote distribution facilities. The Company also provides one of the industry’s most widely used hydraulic fracture simulation software FracPro, as well as hydraulic fracture design and consulting services. In addition, the Company provides a broad range of technologies for spill prevention, containment and countermeasures to oil and gas and industrial markets. Currently, the Company only expects to operate its New Iberia, Louisiana and McIntyre, Georgia plants.

Beginning in late 2014, a severe decline in oil and natural gas prices led to a significant decline in oil and natural gas industry drilling activities and capital spending. Beginning in 2015, the Company implemented a number of initiatives to preserve cash and lower costs, including: reducing workforce across the organization, lowering production output levels in order to align with lower demand, limiting capital expenditures and reducing dividends. The Company incurred severance costs of $~~924~~841 and $~~287~~924 during ~~2018~~2019 and ~~2017~~2018, respectively, as a result of these actions. During 2019, $292 and $549 of these costs were included within Cost of Sales and Selling, General, and Administrative, respectively, and during 2018, $734 and $190 of these costs were included within Cost of Sales and Selling, General, and Administrative, respectively. These costs related principally to the Oilfield and Industrial Technologies and Services segment.

Code

On March 28, 2020, the Debtors entered into a restructuring support agreement (the “RSA”) with the holders of all of the loans outstanding under the Amended and Restated Credit Agreement, dated as of March 2, 2017 (as amended, the “Credit Agreement”), by and among CARBO, as borrower, AGPI and StrataGen, as guarantors, Wilks Brothers, LLC, as administrative agent and lender (“Wilks”), Equify Financial, LLC (“Equify”), as lender (together with Wilks, the “Supporting Lenders”) that sets forth the terms of a prenegotiated Chapter 11 plan of reorganization (the “Plan”) pursuant to which, among other things and subject to the terms and conditions of the RSA, each Supporting Lender will receive its pro rata share of 100% of the equity interests in a reorganized CARBO entity (“Reorganized CARBO” and such interests, the “Reorganized CARBO Interests”) in exchange for its secured claims under the Credit Facility and its claims under the DIP Facility described below, except to the extent such DIP Facility claims are converted into borrowings under an exit credit facility, with Reorganized CARBO retaining (i) 100% of the equity interests in a reorganized AGPI entity and (ii) 100% of the equity interests in a reorganized StrataGen entity. In addition, pursuant to the Plan, a liquidating trust (the “Liquidating Trust”) will be established for the benefit of general unsecured creditors. The Supporting Lenders will contribute $100

F-7

to fund the costs of administering the Liquidating Trust, and any avoidance actions that are not otherwise released under the Plan will be transferred to the Liquidating Trust. The Chapter 11 Cases and the restructuring transactions contemplated by the RSA and the Plan (collectively, the “Restructuring”) are expected to result in the cancellation of CARBO’s common stock.

The Bankruptcy Petitions constituted an event of default that accelerated the Debtors’ obligations under the Credit Agreement. However, under the Bankruptcy Code, the Supporting Lenders under the Credit Agreement are stayed from taking any action against the Debtors as a result of this event of default.

Debtor-in-Possession Financing

On March 30, 2020, the Debtors entered into a Superpriority Senior Secured Debtor-in-Possession Credit Agreement (the “DIP Credit Agreement”), by and among CARBO, as borrower, AGPI and StrataGen, as guarantors, Wilks, as lender, and the other guarantors and lenders from time to time party thereto (any such lenders, together with Wilks, the “DIP Facility Lenders”) providing for a $15 million senior secured superpriority multiple draw term loan facility (the “DIP Facility”). On March 30, 2020, the Bankruptcy Court granted interim approval of the Debtors’ motion to approve the DIP Facility, including the DIP Credit Agreement, and the borrowing by CARBO of up to $5 million of loans thereunder between March 30, 2020 and the Bankruptcy Court’s entry of a final order approving the DIP Facility and DIP Credit Agreement (the “Interim Period Borrowings”).

The Debtors’ obligations under the DIP Credit Agreement are secured by first priority priming liens on substantially all of the Debtors’ assets, subject to certain customary exclusions and carve-outs. Borrowings under the DIP Facility will mature August 29, 2020 (the “Maturity Date”) and will bear interest at a rate of 8.00% per annum. The DIP Credit Agreement also provides for the payment of certain fees, including an unused commitment fee and upfront fee, as well as a DIP fee to be paid to the DIP Facility Lenders in the event the Debtors enter into an alternative debtor-in-possession financing arrangement with financial institutions other than the DIP Facility Lenders in lieu of the DIP Facility. Interest and any other amounts that become due under the DIP Facility will be paid in cash. The proceeds of the DIP Facility, including the Interim Period Borrowings, will be used to pay fees, expenses and other expenditures of the Debtors to be set forth in rolling budgets prepared in connection with the Chapter 11 Cases, subject to the approval of the DIP Facility Lenders and certain stipulated exceptions.

The DIP Credit Agreement terminates on the earliest of: (a) the Maturity Date; (b) the effective date of any Acceptable Plan or any other Chapter 11 Plan (each as defined in the DIP Credit Agreement); (c) the entry of an order for the conversion of any of the Chapter 11 Cases to a case under Chapter 7 of the Bankruptcy Code; (d) the entry of an order for the dismissal of any of the Chapter 11 Cases; and (e) at the election of the Lenders, the date on which any event of default under the DIP Credit Agreement is continuing.

On April 8, 2020, the Debtors filed the Plan and a Disclosure Statement for the Debtors’ Joint Chapter 11 Plan of Reorganization (the “Disclosure Statement”).

Going Concern and Financial Reporting in Reorganization

F-8

Principles of Consolidation

The consolidated financial statements include the accounts of CARBO Ceramics Inc. and its operating subsidiaries. All significant intercompany transactions have been eliminated.

Concentration of Credit Risk, Accounts Receivable and Other Receivables

The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. Receivables are generally due within 30 days. The majority of the Company’s receivables are from customers in the petroleum pressure pumping industry, as well as industrial and environmental industries. The Company establishes an allowance for doubtful accounts based on its assessment of collectability risk and periodically evaluates the balance in the allowance based on a review of trade accounts receivable. Trade accounts receivable are periodically reviewed for collectability based on customers’ past credit history and current financial condition, and the allowance is adjusted if necessary. Credit losses historically have been insignificant. The allowance for doubtful accounts at December 31, 2019 and 2018 was $2,216 and $1,279, respectively. Other receivables were $155 and $442 as of December 31, 2019 and 2018, respectively, of which related mainly to miscellaneous receivables in the United States.

doubtful accounts based on its assessment of collectability risk and periodically evaluates the balance in the allowance based on a review of trade accounts receivable. Trade accounts receivable are periodically reviewed for collectability based on customers’ past credit history and current financial condition, and the allowance is adjusted if necessary. Credit losses historically have been insignificant. The allowance for doubtful accounts at December 31, 2018 and 2017 was $1,279 and $1,602, respectively. Other receivables were $442 and $546 as of December 31, 2018 and 2017, respectively, of which related mainly to miscellaneous receivables in the United States.

Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The carrying amounts reported in the balance sheet for cash equivalents approximate fair value.

Restricted Cash

A portion of the Company’s cash balance is restricted to its use in order to provide collateral primarily for letters of credit and funds held in escrow relating to the sale of its Millen plant. As of December 31, ~~2018~~2019 and ~~2017~~2018, total restricted cash was $109,~~565~~729 and $10,~~216~~565, respectively. As a result of the Company’s non-payment of certain obligations and the Chapter 11 cases, certain beneficiaries to some of our standby letters of credit requested draws that are in progress, and such draws and any additional draws on our standby letters of credit will reduce our restricted cash balance.

Inventories

Inventories are stated at the lower of net realizable value or cost. Finished goods inventories include costs of materials, plant labor and overhead incurred in the production of the Company’s products and costs to transfer finished goods to distribution centers.

The Company evaluated the carrying values of its inventories as of December 31, 2019 and concluded that nofor certain inventories net realizable value had fallen below carrying costs. Consequently, the Company recognized $4,268 lower of cost or net realizable value adjustments in cost of sales to adjust inventory to the lower net realizable value. No such adjustments were required in 2018. The orCompany ~~2017~~evaluates inventory on a per product and location basis.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Repair and maintenance costs are expensed as incurred. Depreciation is computed on the straight-line method for financial reporting purposes using the following estimated useful lives:

Buildings and improvements		15 to 30 years
Machinery and equipment		3 to 30 years
Land-use rights		30 years

The Company holds approximately 2,~~957~~288 acres of land and leasehold interests containing kaolin reserves near its plants in Georgia and Alabama. The Company also holds approximately ~~469~~313 acres of land and leasehold interests containing sand reserves near its sand processing facility in Marshfield, Wisconsin. The capitalized costs of land and mineral rights as well as costs incurred to develop such property are amortized using the units-of-production method based on estimated total tons of these reserves.

Impairment of Long-Lived Assets and Intangible Assets

Long-lived assets to be held and used and intangible assets that are subject to amortization are reviewed for impairment whenever events or circumstances indicate their carrying amounts might not be recoverable. Recoverability is assessed by comparing the undiscounted expected future cash flows from the assets with their carrying amount. If the carrying amount exceeds the sum of the undiscounted future cash flows an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Intangible assets that are not subject to amortization are tested for impairment at least annually by comparing their fair value with the carrying amount and recording an impairment loss for any excess of carrying amount over fair value. Fair values are generally determined based on discounted expected future cash flows or appraised values, as appropriate. For additional information on the Company’s long-lived assets and intangible assets impairment assessment, please refer to Note 5 – Other Operating (Income) Expense.

Intangible assets that are not subject to amortization are tested for impairment at least annually by comparing their fair value with the carrying amount and recording an impairment loss for any excess of carrying amount over fair value. Fair values are generally determined based on discounted expected future cash flows or appraised values, as appropriate. For additional information on the Company’s long-lived assets and intangible assets impairment assessment, please refer to Note 5 – Other Operating Expense (Income).

Manufacturing Production Levels Below Normal Capacity

As a result of the Company substantially reducing manufacturing production levels, including by idling and mothballing certain facilities, the component of the Company’s accounting policy for inventory relating to operating at production levels below normal capacity was triggered and resulted in certain production costs being expensed instead of being capitalized into inventory. The Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. For the years ended December 31, 2019 and 2018, the Company expensed $31,218 and $32,509, respectively, in production costs.

production at normal production levels. For the years ended December 31, 2018 and 2017, the Company expensed $32,509 and $40,664, respectively, in production costs.

Capitalized Software

The Company capitalizes certain software costs, after technological feasibility has been established, which are amortized utilizing the straight-line method over the economic lives of the related products, generally not to exceed five years.

Goodwill

Goodwill represents the excess of the cost of companies acquired over the fair value of their net assets at the date of acquisition. Goodwill relating to each of the Company’s reporting units is tested for impairment annually, during the fourth quarter, as well as when an event, or change in circumstances, indicates an impairment is more likely than not to have occurred. For additional information on the Company’s goodwill impairment assessment, please refer to Note 5 – Other Operating Expense (Income) ~~Expense~~.

Revenue Recognition

Revenue from proppant sales is recognized when title passes to the customer, generally upon delivery. Revenue from consulting and contract manufacturing is recognized at the time service is performed. Revenue from the sale of fracture simulation software is recognized when title passes to the customer at time of shipment. Revenue from the sale of spill prevention services is recognized at the time service is performed. Revenue from the sale of containment goods is recognized at the time goods are delivered.

Shipping and Handling Costs

Shipping and handling costs are classified as cost of sales. Shipping costs consist of transportation costs to deliver products to customers. Handling costs include labor and overhead to maintain finished goods inventory and operate distribution facilities.

Cost of Start-Up Activities

Start-up activities, including organization costs, are expensed as incurred. There were no start-up costs for ~~2018~~2019 and ~~2017~~2018.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Research and Development Costs

Research and development costs are charged to operations when incurred and are included in Selling, General and Administrative expenses. The amounts incurred in ~~2018~~2019 and ~~2017~~2018 were $3,~~823~~351 and $43,~~417~~823, respectively.

F-10

Leases

The Company accounts for its leases in accordance with the requirements of ASC 842, Leases. We determine if an arrangement is a lease at inception. Leases with an initial term of twelve months or less are not recorded on the balance sheet. Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. We have lease agreements with lease and non-lease components, which are accounted for as a single lease component, primarily related to railroad equipment leases. Operating leases are included in operating lease ROU assets, operating lease liabilities, and noncurrent operating lease liabilities on our consolidated balance sheets. Sublease and rental income are recognized as revenue on the consolidated statement of operations.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Intangibles and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 will be effective for the interim and annual periods beginning after December 15, 2019, with early adoption permitted, and will be applied on a prospective basis. The Company early adopted this ASU during 2019 which eliminated Step 2 of the goodwill impairment test. The Company recorded a goodwill impairment during the fourth quarter of 2019 in accordance with the new guidance. See Note 5 for additional information.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which amends current lease guidance. This guidance requires, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements”, which simplifies the implementation by allowing entities the option to instead apply the provisions of the new guidance at the effective date, without adjusting the comparative periods presented. The new lease guidance is effective for the interim and annual periods beginning after December 15, 2018 with early adoption permitted. The Company adopted this guidance effective January 1, 2019 without adjusting the comparative periods. In addition, the Company elected the package of practical expedients permitted under the guidance, which among other things, allowed the Company to carry forward the historical lease classification. Upon adoption, the Company’s operating lease ROU asset was approximately $54,668 and its total lease liability was approximately $64,421. As of December 31, 2019, the Company’s operating lease ROU asset was $9,185 and its total lease liability was $55,700. In addition, upon implementation, the Company’s deferred rent balances, recorded primarily within other long-term liabilities and accrued expenses as of December 31, 2018, of approximately $8,300 were removed and recorded to the lease liability. The Company has implemented a lease accounting system for accounting for leases under the new standard. There were no significant impacts to the consolidated statement of operations and consolidated statement of cash flows upon adoption; however, during 2019, the Company recorded an impairment charge of $39,080 associated with its right of use assets. Refer to Note 5 for additional information.

offset with the lease liability. The Company has implemented a lease accounting system for accounting for leases under the new standard. There were no significant impacts to the consolidated statement of operations and consolidated statement of cash flows.

In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date,” which revises the effective date of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”) to interim and annual periods beginning after December 15, 2017, with early adoption permitted no earlier than interim and annual periods beginning after December 15, 2016. In May 2014, the FASB issued ASU 2014-09, which amends current revenue guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company’s analysis of sales contracts under ASC 606 supports the recognition of revenue at a point in time, typically when title passes to the customer upon delivery, for the majority of contracts, which is consistent with the current revenue recognition model. The Company utilized the modified retrospective approach, which requires a cumulative adjustment to retained earnings and no adjustments to prior periods. The Company adopted this guidance as of January 1, 2018. There was no material impact on the Company’s consolidated financial statements or disclosures.

Bauxite raw materials are used in the production of heavyweight ceramic products. As of December 31, 2019, and 2018, the Company has classified as long-term assets those bauxite raw materials inventories that are not expected to be consumed in production during the upcoming twelve-month period.

On May 28, 2019, the Company entered into an agreement with PicOnyx, Inc. (“PicOnyx”) pursuant to which the Company agreed to provide certain services and contribute certain manufacturing assets to PicOnyx in exchange for 9.7 million shares of convertible preferred stock in PicOnyx. At the Company’s election, the preferred stock can be converted into a pre-determined number of shares of common stock. Additionally, the preferred stock has voting rights that give the Company approximately 22% of voting rights based on the number of outstanding shares of PicOnyx stock. As part of its agreement with PicOnyx, the Company is also designated a seat on the PicOnyx Board of Directors. The Company also holds a warrant to purchase additional shares from PicOnyx with a nominal exercise price in the event of certain qualified financings. In addition, the Company entered into a Contract

As of December 31, 2019 and 2018, no amounts were recorded relating to this clause. The Company’s obligations under the ~~New~~Amended Credit Agreement are secured by: (i) a pledge of all accounts receivable and inventory, (ii) cash in certain accounts, (iii) domestic distribution assets residing on owned real property, (iv) the Company’s Marshfield, Wisconsin and Toomsboro, Georgia plant facilities and equipment, and (v) certain real property interests in mines and minerals. ~~Other liens previously in favor of Wells Fargo were released.~~

On March 2, 2017, in connection with entry into the New Credit Agreement, the Company issued a Warrant (the “Warrant”) to Wilks. Subject to the terms of the Warrant, the Warrant entitles the holder thereof to purchase up to 523,022 shares of the Common Stock, at an exercise price of $14.91 per share, payable in cash. The Warrant expires on December 31, 2022. Based on a Form 4 filing with the SEC on December 29, 2017, as of December 31, 2018, Wilks owned approximately 11.2% of the Company’s outstanding common stock, and should Wilks fully exercise the Warrant to purchase an additional 523,022 shares, it would hold approximately 12.8% of the Company’s outstanding common stock. Upon issuance of the Warrant, the Company recorded an increase to additional paid-in capital of $3,871. As of December 31, 2018, the unamortized original issue discount was $2,934.

In May 2016, the Company received proceeds of $25,000 from the issuance of separate unsecured Promissory Notes (the “Notes”) to two of the Company’s Directors. Each Note matures on April 1, 2019 and bears interest at 7.00%. On March 2, 2017, in connection with the New Credit Agreement, the Notes were amended to provide for payment-in-kind, or PIK, interest payments at 8.00% until the lenders under the New Credit Agreement receive two consecutive semi-annual cash interest payments. On April 1, 2017, the Company made a $997 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance. On October 1, 2017, the Company made a $1,043 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance. As of December 31, 2018, the outstanding principal balance of the Notes of $27,040 was recorded within current liabilities based on the April 1, 2019 maturity date.

Interest cost for the years ended December 31, 2018 and 2017 was $8,612 and $8,058, respectively. Interest cost primarily includes interest expense relating to the Company’s debts as well as amortization and the write-off of debt issuance costs and amortization of the original issue discount associated with the New Credit Agreement and Warrant.

5As of December 31, 2019, the Company had $580 of unamortized debt issuance costs relating to the Credit Agreement and Amended Credit Agreement that are presented as a direct reduction from the carrying amount of the long-term debt obligation. As ~~Other~~a ~~Operating~~result ~~(Income)~~of ~~Expense~~the May 2019 repayment, the Company wrote off approximately $137 of unamortized debt issuance costs relating to the Credit Agreement. As a result of the June 2019 refinancing, the Company recorded approximately $218 of debt issuance costs resulting from an amendment fee paid directly to Wilks. The Company had $7,889 and $2,625 in standby letters of credit issued through its banks as of December 31, 2019 and December 31, 2018, respectively, primarily as collateral relating to railcar leases and other obligations.

~~Other~~On ~~operating~~March ~~income~~2, ~~for~~2017, in connection with entry into the ~~year~~Credit ~~ended~~Agreement, the Company issued a Warrant (the “Warrant”) to Wilks. Subject to the terms of the Warrant, the Warrant entitled the holder thereof to purchase up to 523,022 shares of the Common Stock, at an exercise price of $14.91 per share, payable in cash. The Warrant was amended in connection with the Amended Credit Agreement and June 2019 refinancing to revise the exercise price to $4.00 and to extend the expiration date to December 31, ~~2018~~2024.

On April 1, 2019, the Company made a $27,040 payment repaying the outstanding principal balance of the Notes.

~~Given~~Interest the change in the asset groupings of the two facilities and lack of estimated future cash flows associated with the base ceramic production at the Millen facility, the Company identified indicators of impairment at the Millen, Georgia facility as of September 30, 2017. The Company determined that the projected cash flows attributable to the Millen, Georgia facility did not exceed the carrying value of the assets; therefore the Company concluded there was an impairment at that facility. The Company engaged the services of a third party consulting firm to assist with the determination of the fair value of the related assets, which concluded that the assets were impaired. The key assumptions and inputs impacting the fair value include third party data and commentary with respect to the property and equipment at our Millen facility. For machinery and equipment and construction in progress, we used a cost approach to estimate the valuation. We applied a 65 percent downward adjustment to calculated replacement cost based on an analysis of construction documents and historical expenditures to remove non-saleable soft costs such as engineering and installation that would have no value to a market participant. Based on discussions with market participants, a salvage value multiplier ranging from 12 percent to 50 percent of the remaining replacement cost basis was applied to arrive at the estimated fair value for the ~~machinery~~years ~~and~~ended ~~equipment and construction in progress subject to impairment. For real property~~December 31, we2019 ~~used a market~~ and ~~cost~~2018 ~~approach~~was ~~and reconciled the two approaches.

As of September 30, 2019, the Company determined that the carrying amount of the assets located at one of its proppant distribution centers would not be recoverable as efforts to lease or sell the assets have not been successful due to its location. These assets are located on leased land. The land lease was renegotiated during the third quarter of 2019 to reduce our monthly cost, as well as to revise the lease term to end in December 2020. The Company does not expect to exercise the Company renewal options. At the expiration of the lease term in December 2020, any remaining assets would become the property of the lessor. These distribution center assets were previously considered a general corporate asset that was evaluated for impairment in aggregate with other long-lived assets because it was built to distribute various products manufactured from multiple asset groups and was not built to service any one single asset group. When the Company made the decision to abandon the facility, we then evaluated these distribution center assets separately as opposed to aggregated with other long-lived assets. When the Company built this distribution center several years ago, it was originally intended to primarily distribute ceramic proppant in the Permian Basin. Since then, the market for ceramic proppant in that region deteriorated with the majority of operators instead using inexpensive sand proppants. Given that the Company was no longer able to utilize this distribution center for ceramic proppant, the Company leased the facility in 2017 to a third party who used it for transloading sand in the region. During 2019, the market in the Permian Basin further shifted to very inexpensive in-basin sand that does not require the use of a distribution center, as the sand is trucked directly to the wellsite from the mine. Further, during

F-14

the third quarter of 2019, the lease with the third party expired and was not renewed. Given these developments and the expectation for them to continue indefinitely, there is no business need for these distribution center assets in the region. As we do not expect to renew the lease and efforts to locate a buyer have not been successful, the Company concluded to abandon the long-lived assets and has recorded an impairment of $8,101, within other operating expenses on the statement of operations. The Company wrote the assets down to a salvage value of $0 given that no interested buyers were identified while marketing the assets at scrap values. In addition to this lease, certain other right of use operating lease assets were abandoned during the third quarter of 2019, and as a result we recorded an impairment to the right of use assets totaling $3,886. See Note 6.

Due to worsening market conditions and outlook and the loss of a key customer during the fourth quarter of 2019, the Company identified indicators of impairment for all of our long-lived asset groups. The Company compared forecasted undiscounted cash flows to the net book value for each asset group and completed fair value assessments for all asset groups where the net book value exceeded the forecasted undiscounted cash flows. Our forecasted undiscounted cash flow analysis for our McInytre, Georgia manufacturing facility, which was previously impaired in a prior year, and certain general corporate assets exceeded the book value of those assets, and as such no further analysis was required. However, the Company recognized an impairment charge totaling $169,872 primarily related to (1) our Toomsboro, Georgia manufacturing plant, (2) our technology assets, including our Eufaula, Alabama and New Iberia, Louisiana manufacturing plants, (3) our sand assets, including our Marshfield, Wisconsin facility and (4) various general corporate assets primarily related to distribution centers we no longer intend to utilize in our business. The Company engaged the services of a third party consulting firm to assist with the determination of the fair value of the related assets that were determined to be impaired. The fair value of those impaired assets at December 31, 2019 was estimated at approximately $34,421 based on Level 3 inputs, primarily using a cost and market approach. For real property, we used the market (sales comparison) and/or the cost approaches to value each location on a value in exchange premise. In using the market approach for our Toomsboro facility, we determined that the value of comparable property ranged from approximately $14.21 to $21.79 per square foot, and the concluded value of the property at the Toomsboro facility was approximately $18.00 per square foot. In using the market approach for our technology asset group (including the New Iberia and Eufaula facilities), we determined that the value of comparable property ranged from approximately $6.37 to $12.67 per square foot with a concluded value of approximately $10.00 per square foot for the New Iberia facility, and a range from approximately $11.25 to $19.55 per square foot with a concluded value of approximately $15.00 per square foot for the Eufaula facility. In using the market approach for our Marshfield facilities, we determined that the value of comparable properties ranged from approximately $11.40 to $18.75 per square foot, and the concluded value of the properties at the Marshfield facility was approximately $15.00 per square foot. Excess land at Marshfield was valued at $0.10 per square foot of land area. For the distribution centers, we relied primarily on the market approach to value the land and the cost approach to estimate the contributory value of the improvements. The land values ranged from a low of $0.20 per square foot to $5.00 per square foot of land area, depending on location. The contributory value of improvements ranged from approximately $21.00 to $56.00 per square foot of improved building area, depending on the improvements and location. For machinery and equipment, we considered all approaches to value. As the underlying assets were not supported by cashflows from operating activities, we applied downward adjustments to account for liquidation and / or floor values to sell the assets on an as-is where-is basis. This resulted in valuing the machinery and equipment at salvage values as noted by market participants and published sources, ranging from zero to seven percent of replacement cost depending on the underlying asset type and status. When valuing assets on an in exchange basis, certain assets such as software, computer equipment, lab equipment or abandoned CIP would have very little to no value, and were based upon a zero percent salvage value. Major equipment at the idled locations was noted at a three and a half percent (3.5%) salvage value and active equipment was based upon a seven percent (7.0%) salvage value.

In addition, during the fourth quarter of 2019, as a result of the change in the outlook of our business and the idling of our Marshfield sand facility which utilized a significant portion of our fleet of railcars, we have an excess number of railcars that we no longer expect to utilize in our business, and historical and current efforts to locate sublessees have not been successful. In addition, we previously utilized a leased distribution center in our sand business, and as a result of the idling of our sand business, we no longer expect to utilize this leased distribution center, and efforts to locate a sublessee have not been successful. We expect the majority of our future sales will require customer pick-up at our manufacturing facilities, which eliminates the need for a large number of railcars and distribution centers. These assets were previously treated as general corporate assets that were evaluated for impairment in aggregate with other long-lived assets because they were designed to transport and distribute various products manufactured from multiple asset groups and were not designed to service any one single asset group. When the Company made the decision to abandon the assets, we then evaluated these railcar and distribution center right of use assets separately as opposed to aggregated with other long-lived assets. As a result, the Company recorded an impairment of the abandoned railcar operating lease right of use assets, as well as the distribution center operating lease right of use asset. The Company estimated a salvage value of $0 associated with these lease assets given its inability to find interested sublessees, the excess supply of similar railcars in the market, and the shift to in-basin sand described above. In addition, the Company made the decision that it will vacate certain leased office space during 2020, and as a result have recorded an additional impairment to operating lease right of use assets. This lease asset was for the Company’s corporate headquarters; as such, it was previously treated as a general corporate asset that was evaluated for impairment in aggregate with other long-lived assets. When the Company made the decision to abandon the leased office space, we then evaluated the operating lease right of use asset separately as opposed to aggregated with other long-lived assets. The Company estimated a salvage

F-15

value of $0 associated with this office lease space based on its inability to find interested sublessees and the excess of vacant commercial office space in the area where the lease is held. The total amount of right of use asset impairments recorded during the fourth quarter of 2019 was approximately $35,194. See Note 6.

In addition, the Company identified indicators of impairment relating to our PicOnyx investment, and as a result recorded an impairment of $4,130 during the fourth quarter of 2019. See Note 3.

If there are changes to our material assumptions, it is possible that we may have to recognize additional impairments in the future. However, we believe that the material assumptions used in our impairment analysis were reasonable and were based on available information and forecasts at the time. We continue to monitor whether or not events or circumstances would indicate that the carrying value of any of our long-lived assets might not be recoverable.

The Company assesses goodwill for possible impairment annually or sooner if circumstances indicate possible impairment may have occurred. The Company evaluated goodwill for impairment during the fourth quarter of 2019. The Company has been marketing for sale all or a portion of the Company to various parties. As a result of this marketing effort and various indications of interest, the Company estimated that the fair value of StrataGen, Inc. was less than the carrying value of identifiable assets, and as a result a $3,500 impairment was recorded to goodwill.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. As of December 31, 2019, it is not reasonably certain that we will exercise any of these options, except for our Houston technology center. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components, which are accounted for as a single lease component, primarily related to railroad equipment leases.

The components of lease cost were as follows:

Short-term lease cost		2,928
Variable lease cost		83
Sublease income ^(a)		(2,791	)
Net lease cost	$	14,668

^(a) As a result of the adoption of ASC 842, sublease income is classified within revenues for the year ended December 31, 2019. Prior to the adoption, sublease income was recorded as a reduction to cost of sales. Sublease income for the year ended December 31, 2019 excludes rental income from owned assets of $1,383, respectively, which is recorded within revenues.

Future minimum lease payments under non-cancellable leases as of December 31, 2019 were as follows:

The chart presented above is reflective of the contractual payments due prior to our bankruptcy filing. However, as a result of the defaults resulting from our filing of the Bankruptcy Petitions, we have reclassified non-current operating lease liabilities to current liabilities as of December 31, 2019.

The adoption of ASC 842 resulted in the Company recording a right of use asset of $56,591 and a total lease liability of $64,877 on January 1, 2019. The Company also reduced its other long-term liabilities by approximately $6,500 and accrued expenses by approximately $1,800 as of January 1, 2019 given that deferred rent is now included within the total lease liability. These adjustments represented non-cash changes during the year ended December 31, 2019.

As a result of the significant decline in oil and gas activities and net losses incurred over the past few years, the Company determined during the year ended December 31, 2017 that it was more likely than not that a portion of its deferred tax assets will not be realized in the future. Accordingly, the Company established a $72,380 valuation allowance against its deferred tax assets as of December 31, 2018. The Company’s assessment of the realizability of its deferred tax assets is based on the weight of all available evidence, both positive and negative, including future reversals of deferred tax liabilities.

be realized in the future. The Company’s valuation allowance against its deferred tax assets was $143,379 as of December 31, 2019. The Company’s assessment of the realizability of its deferred tax assets is based on the weight of all available evidence, both positive and negative, including future reversals of deferred tax liabilities.

In December 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted. The Tax Legislation significantly revises the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. In accordance with the Tax Legislation, the Company recorded $28,163 as additional income tax expense in the fourth quarter of 2017 related to the re-measurement of deferred tax assets and liabilities. Additionally, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. December 22, 2018 marked the end of the measurement period for purposes of SAB 118. As such, the Company has completed the analysis based on legislative updates relating to the Tax Legislation. No material changes to the provisional amounts recorded as of December 31, 2017 were identified.

While the Tax Legislation provides for a territorial tax system, beginning in 2018, it includes the global intangible low-taxed income (“GILTI”) provision. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. FASB guidance indicates that accounting for GILTI either as part of deferred taxes or as a period cost are both acceptable methods. As of December 31, 2019 and 2018, the Company has not recognized foreign earnings subject to GILTI. An accounting policy will be elected in the first period in which the GILTI provision becomes applicable to the Company.
