CARBO Ceramics Inc. (the “Company”) is the world’s largest supplier of ceramic proppant and, during 2010, commenced the sale of resin-coated sand in order to broaden its proppant suite of products. The Company is the provider of the industry’s most popular fracture simulation software, and a provider of fracture design and consulting services, and a broad range of technologies for spill prevention, containment and countermeasures. The Company sells the majority of its products and services to operators of oil and natural gas wells and to oilfield service companies to help increase the production rates and the amount of oil and natural gas ultimately recoverable from these wells. The Company’s products and services are primarily used in the hydraulic fracturing of natural gas and oil wells. The Company was incorporated in 1987 in Delaware. As used herein, “Company”, “we”, “our” and “us” may refer to the Company and/or its consolidated subsidiaries.

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. The higher initial cost of ceramic proppant is justified by the fact that the use of these proppants in certain well conditions 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.

The Company primarily manufactures five distinct ceramic proppants. CARBOHSP^® and CARBOPROP^® are high strength proppants designed primarily for use in deep oil and gas wells. CARBOHSP^® has the highest strength of any of the ceramic proppants manufactured by the Company and is used primarily in the fracturing of deep oil and gas wells. CARBOPROP^® is slightly lower in weight and strength than CARBOHSP^® and was developed for use in deep oil and gas wells that do not require the strength of CARBOHSP^®.

CARBOLITE^®, CARBOECONOPROP^® and CARBOHYDROPROP^® are lightweight ceramic proppants. CARBOLITE^® is used in medium depth oil and gas wells, where the additional strength of ceramic proppant may not be essential, but where higher production rates can be achieved due to the product’s uniform size and spherical shape. CARBOECONOPROP^® was introduced to compete directly with sand-based proppant, and CARBOHYDROPROP^® was introduced in late 2007 to improve performance in “slickwater” fracture treatments.

In addition, the Company manufactures 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 incorporated into proppant granules during the manufacturing process, and can be added to any of the types of ceramic proppant that the Company makes.

During the year ended December 31, 2012, the Company generated approximately 77% of its revenues in the United States and 23% in international markets.

The Company also sells fracture simulation software and provides fracture design, engineering and consulting services to oil and natural gas companies worldwide through its wholly-owned subsidiary, StrataGen, Inc. The Company provides a suite of stimulation software solutions to the industry that have marked capabilities for on-site real-time analysis. This has enabled recognition and remediation of potential stimulation problems. This stimulation software is tightly integrated with reservoir simulators, thus allowing for stimulation treatment and production optimization. The Company’s specialized engineering team consults and works with operators around the world to help optimize well placement, fracture treatment design and production stimulation. The broad range of expertise of the Company’s consultants includes: fracture treatment design; completion engineering support; on-site treatment supervision, engineering and quality control; post-treatment evaluation and optimization; reservoir and fracture engineering studies; rock mechanics and software application and training.

Demand for most of the Company’s products and services depends primarily upon the demand for natural gas and oil and on the number of natural gas and oil wells drilled, completed or re-completed worldwide. More specifically, the demand for the Company’s products and services is dependent on the number of oil and natural gas wells that are hydraulically fractured to stimulate production.

The Company also provided a broad range of technologies and products for geotechnical monitoring through its wholly owned subsidiary Applied Geomechanics, Inc. (“AGI”). The AGI business was wound down, and the Company exited this business in late 2012.

Falcon Technologies and Services, Inc. (“Falcon Technologies”), a wholly-owned subsidiary of the Company, provides spill prevention, containment and countermeasure systems for the oil and gas industry. Falcon Technologies uses proprietary technology to provide products that are 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.

As the demand for resin-coated and ceramic proppant continues to be amplified by the large resource plays, the Company expects more entrants into the market for its products. One of the Company’s 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 each of the Company’s products. Saint-Gobain’s primary manufacturing facility is located in Fort Smith, Arkansas. Saint-Gobain also manufactures ceramic proppant in China. Mineracao Curimbaba (“Curimbaba”), based in Brazil, is also a competitor and manufactures ceramic proppants that it markets in competition with some of the Company’s products. Imerys, S.A., based in France (“Imeyrs”), has begun to manufacture ceramic proppant in the State of Georgia, and is also a competitor of the Company. In addition, Pyramax, LLC is constructing a ceramic proppant plant in the State of Georgia, and may become a competitor of the Company once the plant is completed.

There are two major manufacturers of ceramic proppant in Russia. Borovichi Refractory Plant (“Borovichi”) located in Borovichi, Russia, and FORES Refractory Plant (“FORES”) located in Ekaterinburg, Russia. Although the Company has limited information about Borovichi and FORES, the Company believes that Borovichi primarily manufactures intermediate strength ceramic proppants and markets its products principally within Russia, and that FORES manufactures intermediate strength and lightweight ceramic proppant lines and markets its products both inside and outside of Russia. The Company further believes that these companies have added manufacturing capacity in recent years and now provide a majority of the ceramic proppant used in Russia. The

Company is also aware of an increasing number of manufacturers in China. Most of these companies produce intermediate strength ceramic proppants that are marketed both inside and outside of China. Chinese proppant imports into the United States increased beginning in 2011.

Competition for CARBOHSP^® and CARBOPROP^® principally includes ceramic proppant manufactured by Saint-Gobain, Curimbaba and various producers located in China. The Company’s 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 medium depth natural gas and oil wells. The leading suppliers of mined sand are Unimin Corp., U.S. Silica Company, Badger Mining Corp., Fairmount Minerals Limited, Inc., and Ogelbay-Norton Company. The leading suppliers of resin-coated sand are Momentive Specialty Chemicals (formerly known as Hexion) and Santrol, a subsidiary of Fairmount Minerals.

The Company believes that the most significant factors that influence a customer’s decision to purchase the Company’s ceramic proppant are (i) price/performance ratio, (ii) on-time delivery performance, (iii) technical support and (iv) proppant availability. The Company believes that its products are competitively priced and that its delivery performance is good. The Company also believes that its superior technical support has enabled it to persuade customers to use ceramic proppant in an increasingly broad range of applications and thus increased the overall market for the Company’s products. Over the past five years, the Company has increased its manufacturing and resin-coating capacity by nearly 60% and plans to continue its strategy of adding capacity, as needed, to meet anticipated future increases in sales demand.

The Company continually conducts testing and development activities with respect to alternative raw materials to be used in the Company’s existing and alternative production methods. More specifically, the Company has developed a new ceramic proppant with increased strength and conductivity when compared to its traditional products. This new product is intended for use in ultra-high stress wells. The Company is currently scaling up its research and development pilot plant for commercial production, and plans to introduce this product before the end of 2013. Accordingly, quantities of this new product are expected to be limited during 2013. The Company continues to evaluate ways in which the technology utilized in this new product development may be applicable to its other product offerings. For information regarding the Company’s research and development expenditures see Note 1 to the “Notes to Consolidated Financial Statements.”

The Company is actively involved in the development of alternative products for use as proppant in the hydraulic fracturing process and is aware of others engaged in similar development activities. The Company believes that while there are potential specialty applications for these products, they will not significantly impact the use of ceramic proppants. The Company believes that the “know-how” and trade secrets necessary to efficiently manufacture a product of consistently high quality are difficult barriers to entry to overcome.

The Company’s largest customers are participants in the petroleum pressure pumping industry. Specifically, Halliburton Energy Services, Inc. and Schlumberger Limited each accounted for more than 10% of the Company’s 2012 and 2011 revenues. However, the end users of the Company’s products are the operators of natural gas and oil wells that hire the pressure pumping service companies to hydraulically fracture wells. The Company works both with the pressure pumping service companies and with the operators of natural gas and oil wells to present the technical and economic advantages of using ceramic proppant. The Company generally supplies its customers with products on a just-in-time basis, as specified in individual purchase orders. Continuing sales of product depend on the Company’s direct customers and the well operators being satisfied with product quality, availability and delivery performance. The Company provides its software simulation products and consulting services directly to owners and/or operators of oil and gas wells and service companies.

The Company recognizes the importance of a technical marketing program in demonstrating long-term economic advantages when selling products and services that offer financial benefits over time. The Company has a broad technical sales force to advise end users on the benefits of using ceramic proppant, resin-coated sand and performing fracture simulation and consultation services.

Although the Company’s initial products were originally intended for use in deep wells that require high-strength proppant, the Company believes that there is economic benefit to well operators of using ceramic proppant in shallower wells that do not necessarily require a high-strength proppant. The Company believes that its new product introductions and education-based technical marketing efforts have allowed it to capture sales in recent years and will continue to do so in the future.

The Company provides a variety of technical support services and has developed computer software that models the return on investment achievable by using the Company’s ceramic proppant versus alternatives in the hydraulic fracturing of a natural gas or oil well. In addition to the increased technical marketing effort, the Company from time to time engages in field trials to demonstrate the economic benefits of its products and validate the findings of its computer simulations. Periodically, the Company provides proppant to production companies for field trials, on a discounted basis, in exchange for a production company’s agreement to provide production data for direct comparison of the results of fracturing with ceramic proppant as compared to alternative proppants.

The Company’s international marketing efforts are conducted primarily through its sales offices in Dubai, United Arab Emirates; Aberdeen, Scotland; Beijing, China; and Moscow, Russia, and through commissioned sales agents located in South America. The Company’s products and services are used worldwide by U.S. customers operating domestically and abroad, and by foreign customers. Sales outside the United States accounted for 23%, 21% and 23% of the Company’s sales for 2012, 2011 and 2010, respectively. The distribution of the Company’s international and domestic revenues is shown below, based upon the region in which the customer used the products and services:

The Company believes that constructing adequate capacity ahead of demand while incorporating new technology to reduce manufacturing costs are important competitive strategies to increase its overall share of the market for proppant.

Between 2006 and 2011, the Company, in successive phases, completed construction of four production lines at its manufacturing facility in Toomsboro, Georgia. The stated annual production capacity at this facility is 1.0 billion pounds per year.

During 2010, the Company began production from a resin-coating plant that was built within the existing manufacturing infrastructure of its New Iberia, Louisiana facility. The resin-coating plant is utilized to coat both ceramic proppant manufactured at other Company locations and raw frac sand. A second resin-coating production line at the facility was completed in 2012. The facility also functions as a distribution center.

During 2012, the Company began to utilize its own CARBO Northern White sand in its sand processing facility in Marshfield, Wisconsin. This facility supplies sand to the resin-coating facility in New Iberia.

The following table sets forth the current stated capacity of each of the Company’s existing manufacturing and resin-coating facilities:

In 2011, the Company completed the acquisition of real estate to construct a ceramic proppant plant in the Millen, Georgia area. The Company is moving forward with initial site preparation and construction of the first 250 million pound line and anticipates the Millen plant could commence operation near the end of the first quarter of 2014. Engineering and procurement activities commenced for a 600 million pound per year resin-coating plant in Marshfield, Wisconsin but the Company has deferred construction at this time. The Company will consider resuming construction activities on this resin-coating plant when warranted by market conditions. Additionally, the Company is currently scaling up its research and development pilot plant for commercial production of the new ceramic proppant product that it plans to introduce before the end of 2013. The construction of additional manufacturing capacity beyond these new facilities will be dependent on the expected future demand for the Company’s products and the ability to obtain necessary environmental permits.

The Company generally supplies its domestic pumping service customers with products on a just-in-time basis and operates without any material backlog.

Long-lived assets, consisting of net property, plant and equipment, goodwill, intangibles, and other long-term assets as of December 31 in the United States and other countries are as follows:

The Company maintains finished goods inventories at each of its manufacturing facilities and at remote stocking facilities. The North American remote stocking facilities consist of bulk storage silos with truck trailer loading facilities, as well as rail yards for direct transloading from rail car to tank trucks. 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, the Company leases

approximately 2,100 rail cars for use in the distribution of its products and expects to add approximately 250 more railcars by the end of 2013. The price of the Company’s products sold for delivery in the lower 48 United States and Canada typically includes just-in-time delivery of proppant to the operator’s well site, which eliminates the need for customers to maintain an inventory of ceramic proppant. The Company expands its distribution network as needed, including rail car additions as well as increasing finished goods storage capacity at stocking locations. During the fourth quarter of 2012, the Company completed an expansion of its distribution facility in South Texas and is targeting completion of an additional distribution center in the Bakken region in the second half of 2013.

Ceramic proppant is 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. Bauxite is largely used in the production of aluminum metal, refractory material and abrasives. 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.

For the production of CARBOHSP^® and CARBOPROP^® in the United States the Company uses bauxite, and has historically purchased its annual requirements at the seller’s current prices. The Company believes that its ability to purchase bauxite on the open market and current bauxite inventories will sufficiently provide for its bauxite needs in the United States during 2013.

The Company’s Eufaula, McIntyre and Toomsboro facilities primarily use locally mined kaolin for the production of CARBOLITE^®, CARBOECONOPROP^® and CARBOHYDROPROP^®. The Millen facility, currently under construction, will also use locally mined kaolin in its productions processes. The Company has entered into bi-lateral contracts that require a supplier to sell to the Company, and the Company to purchase from the supplier, at least fifty percent of the Eufaula facility’s and Millen facility’s annual kaolin requirements. The Eufaula contract runs through 2017, with options to extend this agreement for additional three year terms. The Millen contract will begin upon the date in which the plant commences operations and extend for an initial period of five years, with options to extend the agreement for an additional five years. The Company has obtained ownership rights in acreage in Wilkinson County, Georgia, which contains in excess of a fifteen year supply of kaolin for its Georgia facilities at current production rates. The Company has 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 the Company to utilize the third party to mine and transport a majority of the McIntyre facility’s annual kaolin requirement.

The Company’s production facility in Luoyang, China, uses both kaolin and bauxite for the production of CARBOPROP^® and CARBOLITE^®. Certain of these materials are purchased under a long-term contract that stipulates fixed prices subject to periodic adjustment and provides for minimum purchase requirements.

The Company’s production facility in Kopeysk, Russia currently uses bauxite for the production of CARBOPROP^®. Bauxite is purchased under annual agreements that stipulate fixed prices for up to a specified quantity of material.

The Company continues to explore options for the purchase of high quality raw materials for its resin-coated sand business. In 2011, the Company secured a five-year contract with a supplier and consummated the purchase of two parcels of property containing sand reserves. During 2012, the Company began to utilize its own CARBO Northern White sand in its sand processing facility in Marshfield, Wisconsin, which supplies the Company’s resin-coating facility in New Iberia, Louisiana.

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. The Company uses two different methods to produce ceramic

proppant. The Company’s plants in McIntyre, Georgia; Kopeysk, Russia and Luoyang, China use 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.

The Company’s 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 Company makes ceramic proppant and ceramic media used in foundry and scouring processes (the latter two items comprising a minimal volume of overall sales) by processes and techniques that involve a high degree of proprietary technology, some of which is protected by patents.

The Company owns 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 media; however, production of products pursuant to these patents does not currently constitute a material portion of the Company’s output. The Company also owns multiple U.S. and foreign patents that relate to methods for the detection of subterranean fractures.

The Company owns multiple U.S. patent applications (together with a number of counterpart applications pending in foreign jurisdictions). Each of the U.S. patent applications cover ceramic proppant, processes for making ceramic proppant, and detection of subterranean fractures. 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.

The Company believes that its patents have historically been important in enabling the Company to compete in the market to supply proppant to the natural gas and oil industry. The Company intends to enforce, and has in the past vigorously enforced, its patents. The Company may from time to time in the future be involved in litigation to determine the enforceability, scope and validity of its patent rights. In addition to patent rights, and perhaps more notably, the Company uses a significant amount of trade secrets, or “know-how,” and other proprietary information and technology in the conduct of its business. None of this “know-how” and technology is licensed from third parties.

Falcon Technologies owns two U.S. patents, which expire in 2026 and 2027 and relate to construction of secondary containment areas, and multiple U.S patent applications (together with a number of counterpart applications pending in foreign jurisdictions), each of which relates to tank bases, anchoring systems, or methods of constructing secondary containment areas.

The Company believes that its 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 air and water pollutants from the Company’s 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 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 of Environmental Quality, the Louisiana Department of Environmental Quality, the Alabama Department of Environmental Management, the Wisconsin Department of Natural Resources, and the Georgia Environmental Protection Division, in states in which we do business, have environmental regulations applicable to our operations. 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 and obtaining these permits in a timely manner will continue to be an important factor in the Company’s ability to do so in the future.

As of December 31, 2012, the Company had 992 employees worldwide. In addition to the services of its employees, the Company employs the services of consultants as required. The Company’s 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. The Company believes its relations with its employees are satisfactory.

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.

Our business and financial performance depend 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 closely related to the number of natural gas and oil wells completed in geologic formations where ceramic or resin-coated sand proppants are used in fracture treatments. These activity levels are affected by both short-term and long-term trends in natural gas and oil prices. In recent years, natural gas and oil 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. 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 the second half of 2011 and continued throughout 2012, which resulted in a decline in the United States drilling rig count during 2012. A prolonged reduction in natural gas and oil prices would generally depress the level of natural gas and oil exploration, development, production and well completions activity and result in a corresponding decline in the demand for our products. Such a decline could have a material adverse effect on our results of operations and financial condition.

Our business and financial performance could suffer if the levels of hydraulic fracturing decrease or cease as a result of the development of new processes, increased regulation or a decrease in horizontal drilling activity.

Substantially all of our products are proppants used in the completion and re-completion of natural gas and oil wells through the process of hydraulic fracturing. 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, it is possible that future federal, state or foreign laws or regulations could otherwise limit or ban hydraulic fracturing. Any of these events could have a material adverse effect on our results of operations and financial condition.

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 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. While we made several distribution and infrastructure investments during 2012, we continue to work on long-term solutions to the changing distribution environment. 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.

The proppant market is highly competitive and no one supplier is dominant. We compete with other domestic and international suppliers of ceramic proppant, as well as with suppliers of sand and resin-coated 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 to supply ceramic proppant could have a material adverse effect on our results of operations and financial condition.

We may be adversely affected by decreased demand for our proppant or the development by our competitors of effective 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. Although we believe that the use of ceramic proppant or resin-coated sand generates higher production rates and more favorable production economics than mined sand, a significant shift in demand from ceramic proppant or resin-coated sand to mined sand could have a material adverse effect on our results of operations and financial condition. The development and use of effective 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.

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

During 2012, our key customers included several of the largest participants in the worldwide petroleum pressure pumping industry. Although 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, two customers accounted collectively for approximately 49% of our 2012 revenues. We generally supply our domestic pumping service customers with products on a just-in-time basis, with transactions governed by individual purchase orders. Continuing sales of product depend on our direct customers and the end user well operators being satisfied with product quality, availability and delivery performance. Although we believe our relations with our customers and the major well operators are satisfactory, a material decline in the level of sales to any one of our major

customers due to unsatisfactory product performance, 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 are subject to a number of operational risks and interruptions and seasonal variations, including inclement weather.

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. We have not historically considered seasonality to be a significant risk, but 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 exposed to seasonal variations and inclement weather. Operations in these regions involve more seasonal risk in the winter months, and work is hindered during other inclement weather events. 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 and 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.

A significant portion of our ceramic proppant is manufactured at one of our plants. Any adverse developments at that plant could have a material adverse effect on our financial condition and results of operations.

Our Toomsboro, Georgia plant represents approximately 47% of our total annual capacity at our existing manufacturing facilities. Any adverse developments at this plant, 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.

Falcon Technologies’ 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 Falcon Technologies responsible in the event of a spill or release under particular circumstances. If Falcon Technologies 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, it is possible 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 will 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.

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 23%, 21% and 23% of our total revenues in 2012, 2011 and 2010, 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:

In particular, we are subject to risks associated with our production facilities in Luoyang, China, and Kopeysk, Russia. The legal systems in both China and Russia are still developing and are subject to change. Accordingly, our operations and orders for products in both countries could be adversely impacted by changes to or interpretation of each country’s law. Further, if manufacturing in either region is disrupted, our overall capacity could be significantly reduced and sales and/or profitability could be negatively impacted.

Resin-coated sand is an alternative to the Company’s traditional ceramic proppant and involves a different manufacturing process that utilizes a different raw material. The expansion of our resin-coated sand operations is driven by market demand and involves capital expenditures and new operational requirements. If we are unable to secure adequate, cost effective supply commitments for the raw materials associated with resin-coated sand or if we are unable to timely and cost effectively construct additional manufacturing capacity and infrastructure to produce resin-coated sand, our ability to sell this product to the marketplace at profitable margins may be adversely impacted. A lack of sales of resin-coated sand or the inability to control the costs associated with manufacturing this product could have a material adverse effect on our results from operations and financial condition.

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.

The market price of our common stock will fluctuate, and could fluctuate significantly.

The market price of the Company’s common stock will fluctuate, and could fluctuate significantly, in response to various factors and events, including the following:

The Company maintains its corporate headquarters in leased office space in Houston and also leases space for its technology center in Houston. The Company owns its manufacturing facilities, land and substantially all of the related production equipment in New Iberia, Louisiana, Eufaula, Alabama, and Kopeysk, Russia and leases its McIntyre and Toomsboro, Georgia, facilities. The Company owns the buildings and production equipment at its facility in Luoyang, China, and has been granted use of the land on which the facility is located through 2051 under the terms of a land use agreement with the People’s Republic of China.

The facilities in McIntyre and Toomsboro, Georgia, include real property, plant and equipment that are leased by the Company from the Development Authority of Wilkinson County. The original lease was executed in 1997 and was last amended in 2008. The term of the current lease, which covers both locations, terminates on November 1, 2013, subject to the Company’s ability to renew the lease through November 2022. Under the terms of the lease, the Company is responsible for all costs incurred in connection with the premises, including costs of construction of the plant and equipment. At the termination of the lease, title to all of the real property, plant and equipment is to be conveyed to the Company in exchange for nominal consideration. The Company has the right to purchase the property, plant and equipment at any time during the term of the lease for a nominal price.

In 2011, the Company purchased land in Millen, Georgia for development and construction of a new ceramic proppant manufacturing facility. The Company is moving forward with initial site preparation and construction of the first 250 million pound line and anticipates the Millen plant could commence operation near

the end of the first quarter of 2014. In November 2012, the Company entered into a lease for the land and improvements associated with the Millen facility. The lease term continues until the tenth anniversary of the completion of the last phase of the facility. Similar to lease terms of the two other Georgia facilities, the Millen lease requires the Company to be responsible for all costs (including construction costs) incurred in connection with the premises. Moreover, title to the real property, plant and equipment of the facility is to be conveyed to the Company at the end of the lease term for nominal consideration, and may be purchased by the Company at any time for a nominal price.

The Marshfield, Wisconsin sand processing plant, which became operational during 2012, and the resin-coating facility for which construction has been currently deferred are located on land owned by the Company.

The Company owns or otherwise utilizes distribution facilities in multiple locations around the world. See “Item 1. Business – Distribution.”

The Company owns approximately 4,150 acres of land and leasehold interests near its plants in Georgia and Alabama. The land contains raw material for use in the production of the Company’s lightweight ceramic proppants. The Company also holds approximately 490 acres of land and leasehold interests in Wisconsin near its resin-coating facility under construction in Marshfield, Wisconsin.

Falcon Technologies owns its service facility located in Decatur, Texas, and leases other regional service facilities within the United States.

On February 9, 2012, the Company and two of its officers, Gary A. Kolstad and Ernesto Bautista III, were named as defendants in a purported class-action lawsuit filed in the United States District Court for the Southern District of New York (the “February SDNY Lawsuit”), brought on behalf of shareholders who purchased the Company’s Common Stock between October 27, 2011 and January 26, 2012 (the “Relevant Time Period”). On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”, and collectively with the February SDNY Lawsuit, the “Federal Securities Lawsuit”). In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated, and will now proceed as one lawsuit. The Federal Securities Lawsuit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. In September 2012, the Company and Messrs. Kolstad and Bautista filed a motion to dismiss this lawsuit. Response and reply briefs on this motion were filed during the fourth quarter of 2012, and a decision from the Court is pending.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “June Harris County Lawsuit”). This lawsuit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit as well as a breach of duty by certain defendants in connection with stock sales. This lawsuit also requests unspecified damages and costs. The parties to the June Harris County Lawsuit have also entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuit.

While each of the Federal Securities Lawsuit and the June Harris County Lawsuit are in their preliminary stages, the Company does not believe they have merit, and plans to vigorously contest and defend against them.

Additionally, from time to time, the Company is the subject of legal proceedings arising in the ordinary course of business. The Company does not believe that any of these proceedings will have a material effect on its business or its results of operations.

The Company cannot predict the ultimate outcome or duration of any lawsuit described in this report.

Several of our U.S. manufacturing facilities process mined minerals, and therefore are viewed as mine operations subject to regulation by the federal Mine Safety and Health Administration under the Federal Mine Safety and Health Act of 1977. Information concerning mine safety violations or other regulatory matters required by section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the recently proposed Item 106 of Regulation S-K (17 CFR 229.106) is included in Exhibit 95 to this annual report.

The Company’s common stock is traded on the New York Stock Exchange (ticker symbol CRR). The number of record and beneficial holders of the Company’s common stock as of February 1, 2013 was approximately 24,696.

The following table sets forth the high and low sales prices of the Company’s common stock on the New York Stock Exchange and dividends for the last two fiscal years:

The Company currently expects to continue its policy of paying quarterly cash dividends, although there can be no assurance as to future dividends because they depend on future earnings, capital requirements and financial condition.

On August 28, 2008, the Company’s Board of Directors authorized the repurchase of up to two million shares of the Company’s common stock. Shares are effectively retired at the time of purchase. The Company did not repurchase any shares under this repurchase plan during the fourth quarter of 2012. As of December 31, 2012, the Company has repurchased and retired 1,877,576 shares at an aggregate price of $78.3 million.

The following table provides information about the Company’s repurchases of common stock during the quarter ended December 31, 2012, all of which represent shares surrendered to the Company for tax withholding obligations upon the vesting of restricted stock:

The graph below compares the cumulative shareholder return on the Company’s common stock with the cumulative returns of the S&P 500 index and the S&P SmallCap 600 - Oil & Gas Equipment & Services index. The graph tracks the performance of a $100 investment in the Company’s common stock and in each of the indexes (with the reinvestment of all dividends) from December 31, 2007 to December 31, 2012.

The following selected financial data are derived from the audited consolidated financial statements of the Company. The data should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto included elsewhere in this Form 10-K. The Company has determined that its outstanding non-vested restricted stock awards are participating securities. Accordingly, effective January 1, 2009, earnings per common share are computed using the two-class method prescribed by ASC Topic 260 “Earnings Per Share.” All previously reported earnings per common share data were retrospectively adjusted to conform to the new computation method.

CARBO Ceramics Inc. generates revenue primarily through the sale of products and services to the oil and gas industry. The Company’s principal business consists of manufacturing and selling ceramic proppant and resin-coated sand for use primarily in the hydraulic fracturing of oil and natural gas wells. Falcon Technologies, a wholly-owned subsidiary of the Company, uses proprietary technology to provide products that are 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. The Company also provides the industry’s most popular hydraulic fracture simulation software FracPro^®, as well as hydraulic fracture design and consulting.

During 2010, the Company began production of resin-coated ceramic (CARBOBOND^® LITE^®) and resin-coated sand (CARBOBOND^® RCS) proppants. The introduction of CARBOBOND^® LITE^® addresses a market in which oil and natural gas wells are subject to a high risk of proppant flow-back. The adhesive property of the resin allows the ceramic proppant pack to adhere in place and therefore reduce the risk of proppant flow-back. In the case of CARBOBOND^® RCS, the Company made the strategic decision to offer a lower cost, lower conductivity alternative to its ceramic proppants thereby broadening its proppant suite of products. Management of the Company believes that this is a natural extension of its core business and enhances the Company’s highly conductive proppant offering.

The Company’s products and services help oil and gas producers increase production and recovery rates from their wells, thereby lowering overall reservoir development costs. As a result, the Company’s business is dependent to a large extent on the level of drilling activity in the oil and gas industry worldwide. Although the Company’s ceramic proppants are more expensive than alternative non-ceramic proppants, the Company has been able to demonstrate the cost-effectiveness of its products to numerous operators of oil and gas wells through increased technical marketing activity. The Company believes its future prospects benefit from both an increase in drilling activity worldwide and the desire of industry participants to improve production results and lower their overall development costs.

The Company believes international sales will continue to represent an important role in its business. International revenues represented 23%, 21% and 23% of total revenues in 2012, 2011 and 2010, respectively.

Management believes the addition of new manufacturing capacity is critical to the Company’s ability to continue its long-term growth in sales volume and revenue for ceramic proppant, resin-coated ceramic proppant and resin-coated sand. In regards to expansion, the Company has been issued an Air Quality Permit for its proposed ceramic proppant manufacturing plant in Millen, Georgia. The Company is moving forward with site work and construction of the first 250 million pound line and anticipates the Millen plant could commence operations near the end of the first quarter of 2014. Upon the completion of the first line, the Company’s total ceramic proppant stated capacity is expected to be 2.0 billion pounds per year. A second resin-coating production line in New Iberia, Louisiana was completed during 2012, bringing the Company’s total resin-coating capacity to 400 million pounds per year. Also during 2012, the Company began to utilize its own CARBO Northern White sand in its sand processing facility in Marshfield, Wisconsin. Construction of a resin-coating facility at this same site in Marshfield has been deferred at this time. The Company will consider resuming construction when warranted by market conditions. Although the Company has operated near or at full capacity at times during the previous ten years, the addition of significant new capacity, as well as the addition of resin-coating capacity, could adversely impact operating profit margins if the timing of this new capacity does not match increases in demand for the Company’s products. In addition, the ability to construct new capacity will be contingent upon the receipt of all needed environmental emission permits. See “Item 1—Business” and “Item 1A—Risk Factors”.

Operating profit margin for the Company’s ceramic proppant business is principally impacted by manufacturing and distribution costs, sales price and the Company’s production levels as a percentage of its capacity. Although most direct production expenses have been relatively stable or predictable over time, the Company has experienced volatility in the cost of natural gas, which is used in production by the Company’s

domestic manufacturing facilities, and bauxite, which is the primary raw material for production of the Company’s high strength ceramic proppant. The cost of natural gas has been a significant component of total monthly domestic direct production expense over the last four years. 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, the Company contracts in advance for portions of its future natural gas requirements. Despite the efforts to reduce exposure to changes in natural gas prices, it is possible that, given the significant portion of manufacturing costs represented by this item, gross margins as a percentage of sales may decline and changes in net income may not directly correlate to changes in revenue. Investments continue to be made to enhance the Company’s distribution capabilities. The Company recently completed an expansion of its distribution center in South Texas. The Company is targeting the completion of an additional distribution center in the Bakken region in the second half of 2013.

With regard to resin-coating and sand operations, during 2012 the Company completed a second resin-coating line at its New Iberia, Louisiana facility and began to utilize its Northern White sand in its sand processing facility in Marshfield, Wisconsin. The production of resin-coated sand is a different process than the manufacture of ceramic proppant, and profit margins associated with resin-coated sand are not as high as those historically received for the Company’s manufactured ceramic proppant.

As the Company has expanded its operations in both domestic and international markets, there has been an increase in activities and expenses related to marketing, research and development, and finance and administration. As a result, selling, general and administrative expenses have increased in recent years. In the future, the Company expects to continue to actively pursue new business opportunities by:

The Company expects that these activities will generate increased revenue. As such, selling, general and administrative expenses may increase in 2013 from 2012 levels as the Company pursues these opportunities and continues to expand its operations.

The Company’s proppant business is impacted by the number of natural gas and oil wells drilled in North America, and the need to hydraulically fracture these wells. In markets outside North America, sales of the Company’s 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, the Company’s business is influenced by the current and expected prices of natural gas and oil.

During the second half of 2009, the North American drilling rig count improved from the lows experienced during the second half of 2008 and stabilized during 2010. Late in 2011, a severe decline in natural gas prices led certain customers to reduce drilling activities and capital spending in natural gas basins and increase these items in liquids-rich basins. Low natural gas prices continued throughout 2012 and operations were impacted by the shift in drilling activity away from natural gas basins. The impact resulting from this shift included higher distribution costs due to the logistical challenges in these infrastructure limited regions and competitive pricing pressures resulting from an over-supply of Chinese ceramic proppant. While natural gas fundamentals remain weak, the continued strength in oilfield activity by the Company’s clients in oily, liquids-rich plays is encouraging.

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

Revenue is recognized when title passes to the customer (generally upon delivery of products) or at the time services are performed. The Company generates a significant portion of its revenues and corresponding accounts receivable from sales to the petroleum pressure pumping industry. In addition, the Company generates a significant portion of its revenues and corresponding accounts receivable from sales to two major customers, both of which are in the petroleum pressure pumping industry. As of December 31, 2012, approximately 46% of the balance in trade accounts receivable was attributable to those two customers. The Company records an allowance for doubtful accounts based on its assessment of collectability risk and periodically evaluates 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 a prolonged economic downturn in the petroleum pressure pumping industry were to occur or, for some other reason, any of the Company’s primary customers were to experience significant adverse conditions, the Company’s 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. At December 31, 2012, the allowance for doubtful accounts totaled $1.8 million.

The Company values inventory using the weighted average cost method. Assessing the ultimate realization of inventories requires judgments about future demand and market conditions. The Company regularly reviews inventories to determine if the carrying value of the inventory exceeds market value and the Company records an adjustment to reduce the carrying value to market value, as necessary. Future changes in demand and market conditions could cause the Company 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 market adjustments may be required.

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 and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts 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 the Company to make certain estimates about its future operations. Changes in state, federal and foreign tax laws, as well as changes in the Company’s financial condition, could affect these estimates.

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.

For the year ended December 31, 2012, the Company reported net income of $105.9 million, a decrease of 19% compared to the $130.1 million reported in the previous year. Operations in 2012 were impacted by the shift in drilling activity away from natural gas basins due to the severe decline in natural gas prices in late 2011. The impact resulting from this shift included higher distribution costs due to the logistical challenges in infrastructure limited regions and competitive pricing pressures resulting from an over-supply of Chinese ceramic proppant. Net income in 2012 decreased primarily as a result of a 5% decrease in the average proppant selling price and a decrease in the proppant gross profit margin as a percentage of sales, partially offset by a 7% increase in proppant sales volume and a greater contribution from the Company’s other business units. Income tax expense in 2012 decreased primarily due to lower pretax income.

For the year ended December 31, 2011, the Company reported net income of $130.1 million, an increase of 65% compared to the $78.7 million reported in the previous year. During 2011, operations continued to be favorably impacted by continued acceptance of the Company’s products and service offerings. Further, additional production capacity from the completion of the third and fourth production lines at the Company’s Toomsboro, Georgia production facility in 2010 and 2011, respectively, enabled the Company to increase sales volumes. Net income in 2011 increased primarily as a result of a 19% increase in proppant sales volume, a 12% increase in the average proppant selling price, and an increase in the gross profit margin as a percentage of sales, partially offset by higher selling, general and administrative expenses. Income tax expense in 2011 increased due to higher pretax income.

Revenues of $645.5 million for the year ended December 31, 2012 increased 3% compared to $625.7 million in 2011. Revenues increased primarily due to a 7% increase in proppant sales volume and an increase in the revenues of some of the Company’s other business units, partially offset by a 5% decrease in the average proppant selling price resulting from competitive pricing pressures. Worldwide proppant sales volume totaled 1.712 billion pounds during 2012 compared to 1.605 billion pounds in 2011. North American (defined as Canada and the U.S.) sales volume increased 3% primarily attributed to an increase in the oil rig count in the U.S. as well as acceptance of the Company’s products in oily, liquids-rich basins. International (excluding Canada) sales volume increased 25% primarily due to increases in China, Russia and Mexico, partially offset by a decrease in Europe. Other Proppants (defined as resin-coated sand, ceramic proppant manufactured on an outsourced basis, and raw sand sold in the course of producing substrate for the resin-coated sand business) represented 169 million pounds of the Company’s worldwide sales volume in 2012, as compared to 129 million pounds in 2011. The average selling price per pound of all proppant, including Company-produced ceramic proppant and Other Proppant, was $0.343 per pound in 2012 compared to $0.360 per pound in 2011.

Revenues of $625.7 million for the year ended December 31, 2011 increased 32% compared to $473.1 million in 2010. Revenues increased primarily due to a 19% increase in proppant sales volume, a 12% increase in the average proppant selling price as a result of price increases and an increase in the revenues of Falcon Technologies. The Company’s worldwide proppant sales volume totaled 1.605 billion pounds during 2011 compared to 1.348 billion pounds in 2010. North American (defined as Canada and the United States) sales volume increased 21% and International (excluding Canada) sales volume increased 12%. North American demand was driven primarily by an increase in the drilling rig count in the United States and Canada as well as continued acceptance of the Company’s products in unconventional resource plays, including shale formations. Additional production capacity from the completion of the third and fourth production lines at the Company’s Toomsboro, Georgia production facility in 2010 and 2011, respectively, enabled the Company to increase sales

volumes. Completion of the first resin-coating line at the Company’s New Iberia, Louisiana production facility during the second quarter of 2010, as well as the purchase of ceramic proppant that meets API and ISO standards and is manufactured on an outsourced basis, also contributed toward improved ability to meet customer demand. Other Proppants represented 129 million pounds of the Company’s worldwide sales volume in 2011, as compared to 66 million pounds in 2010. International sales volume increased primarily due to increases in Russia, Europe and the Asia-Pacific region (including China), partially offset by decreases in Africa and the Middle East. The average selling price per pound of all proppant, including both Company-produced ceramic proppant and Other Proppant, was $0.360 per pound in 2011 compared to $0.322 per pound in 2010.

The Company’s cost of sales related to proppant manufacturing consists of manufacturing costs, packaging and transportation expenses associated with the delivery of the Company’s products to its customers and handling costs related to maintaining finished goods inventory and operating the Company’s remote stocking facilities. Variable manufacturing costs include raw materials, labor, utilities and repair and maintenance supplies. Fixed manufacturing costs include depreciation, property taxes on production facilities, insurance and factory overhead.

Gross profit for the year ended December 31, 2012 was $223.5 million, or 35% of revenues, compared to $261.7 million, or 42% of revenues, for 2011. Operations in 2012 were impacted by the shift in drilling activity away from natural gas basins due to the severe decline in natural gas prices in late 2011 and the resulting logistical challenges and costs and the competitive pricing pressures created by this shift. Despite a 7% increase in proppant sales volume, gross profit and gross profit as a percentage of revenues decreased primarily as a result of a decrease in the average proppant selling price, an increase in freight and logistics costs, higher fixed cost absorption, and a shift in sales mix towards lower-margin heavyweight and Other Proppant products. Greater contribution from the Company’s other business units partially offset the decrease in gross profit from proppant sales.

Gross profit for the year ended December 31, 2011 was $261.7 million, or 42% of revenues, compared to $174.7 million, or 37% of revenues, for 2010. The increase in gross profit, as well as gross profit as a percentage of revenues, were primarily the result of higher proppant sales volume, an increase in the average proppant selling price, a change in product mix, and greater contribution from some of the Company’s other business units.

Operating expenses consisted of $64.0 million of SG&A expenses and $0.6 million of other operating expenses for the year ended December 31, 2012 compared to $62.4 million and $1.7 million, respectively, for 2011. The increase in SG&A expenses primarily resulted from higher administrative spending. Other operating expenses in 2012 consisted primarily of a $0.5 million loss on disposal of assets related to the wind down of the geotechnical monitoring business. Other operating expenses in 2011 consisted primarily of an impairment of goodwill of $0.9 million related to the Company’s geotechnical monitoring business and a write-down of $0.8

million related to a 6% interest in an investment accounted for under the cost method as a result of the sale of the business by majority shareholders. As a percentage of revenues, SG&A and other operating expenses for 2012 remained consistent to 2011.

Operating expenses consisted of $62.4 million of SG&A expenses and $1.7 million of other operating expenses for the year ended December 31, 2011 compared to $52.6 million and $2.4 million, respectively, for 2010. The increase in SG&A expenses primarily resulted from higher marketing, research and development, and administrative spending associated with supporting revenue growth. Other operating expenses in 2011 consisted of start-up costs of $0.2 million primarily related to the start-up of the fourth production line at the Company’s Toomsboro, Georgia facility, an impairment of goodwill of $0.9 million related to the Company’s geotechnical monitoring business and a write-down of $0.8 million related to a 6% interest in an investment accounted for under the cost method as a result of the sale of the business by majority shareholders. Other operating expenses in 2010 consisted of start-up costs of $1.0 million related to the start-up of the first resin-coating line within the Company’s existing manufacturing infrastructure at the New Iberia, Louisiana facility and the third production line at the Company’s Toomsboro, Georgia facility, an impairment of goodwill of $0.4 million related to the Company’s geotechnical monitoring business and a $1.0 million loss on equipment disposals mainly related to the Company’s U.S. manufacturing facilities. As a percentage of revenues, SG&A and other operating expenses in 2011 decreased to 10% compared to 12% for the same period in 2010.

Consolidated income tax expense was $52.7 million, or 33.2% of pretax income, for the year ended December 31, 2012 compared to $67.3 million, or 34.1% of pretax income for 2011. The $14.7 million decrease is due to lower pre-tax income and a lower effective tax rate primarily associated with the final preparation and filing of the Company’s prior year income tax returns and additional tax benefits relating to mining depletion deductions.

Consolidated income tax expense was $67.3 million, or 34.1% of pretax income, for the year ended December 31, 2011 compared to $40.6 million, or 34.0% of pretax income for 2010. The $26.7 million increase is primarily due to higher pretax income.

The Company anticipates that industry activity during 2013 will be similar to that in 2012 and that liquids-rich drilling activity in North America will remain high, offset by low natural gas drilling activity. Overall, the Company believes its operating results for 2013 will continue to be influenced by the level of oil and natural gas drilling in North America. The Company is cautiously optimistic that well completion activity will increase as the year unfolds, however, quarterly fluctuations are possible. Accordingly, the Company believes the supply-demand balance in the proppant market should improve during the year and expects its ability to demonstrate the value of ceramic proppant relative to alternatives will allow it to continue to generate new sales opportunities, especially in oily, liquids-rich plays.

The Company expects to support near-term demand with its current ceramic production capacity of 1.75 billion pounds per year, along with existing inventories of ceramic proppant. The Company has been issued an Air Quality Permit for its proposed ceramic proppant manufacturing plant in Millen, Georgia and is moving forward with site preparation and construction of the first 250 million pound line, which it anticipates could commence operation near the end of the first quarter of 2014.

The increased amount of activity in infrastructure-limited, liquids-rich basins introduced supply chain challenges to the industry and resulted in higher distribution costs during 2012. Although the Company expects these costs will continue at current levels for the near-term, it is making capital investments in certain of these challenged regions to facilitate a reduction of these costs and promote further customer service.

At December 31, 2012, the Company had cash and cash equivalents of $90.6 million compared to cash and cash equivalents of $41.3 million at December 31, 2011. During 2012, the Company generated $156.4 million of cash from operating activities, retained $1.4 million from excess tax benefits relating to stock based compensation and retained $0.2 million from the effect of exchange rate changes on cash. Uses of cash included $77.2 million for capital expenditures, $23.6 million for the payment of cash dividends and $7.9 million for repurchases of the Company’s common stock. In addition, during 2012, the Company borrowed and fully repaid a total of $10.0 million on its credit facility. Major capital spending in 2012 included engineering, procurement and construction of sand processing and resin-coating facilities in Marshfield, Wisconsin and New Iberia, Louisiana, expansion of the Company’s distribution infrastructure, engineering and procurement activities related to the new manufacturing facility in Millen, Georgia, as well as upgrades and improvements at existing manufacturing facilities.

Subject to its financial condition, the amount of funds generated from operations and the level of capital expenditures, the Company’s current intention is to continue to pay quarterly dividends to holders of its common stock. On January 22, 2013, the Company’s Board of Directors approved the payment of a quarterly cash dividend of $0.27 per share to shareholders of the Company’s common stock on February 1, 2013. The dividend is payable on February 15, 2013. The Company estimates its total capital expenditures in 2013 will be between $115.0 million and $135.0 million, which include costs associated with the construction of the new manufacturing facility in the Millen, Georgia area, expansion of the Company’s distribution infrastructure, as well as various other projects and additions.

The Company has historically maintained an unsecured line of credit with a bank. In March 2012, the Company entered into a first amendment to this credit agreement to (i) extend its maturity date from January 29, 2013 to July 29, 2013, (ii) increase the size from $10.0 million to $25.0 million, and (iii) make other administrative changes to certain covenants and provisions. As of December 31, 2012, there was no outstanding debt under the new credit agreement. The Company anticipates that cash on hand, cash provided by operating activities and funds provided by its line of credit will be sufficient to meet planned operating expenses, tax obligations, capital expenditures and other cash needs for the next 12 months. The Company also believes that it could acquire additional debt financing, if needed. Based on these assumptions, the Company believes that its fixed costs could be met even with a moderate decrease in demand for the Company’s products.

The following table summarizes the Company’s contractual obligations as of December 31, 2012:

Operating lease obligations relate primarily to railroad equipment leases and include leases of other property, plant and equipment.

The Company uses natural gas to power its domestic manufacturing plants. From time to time, the Company enters into contracts to purchase a portion of the anticipated natural gas requirements at specified prices. As of December 31, 2012, the last such contract was due to expire in December 2017.

The Company has entered into contracts to supply raw materials, primarily kaolin, bauxite and hydro sized sand, to each of its manufacturing plants. Each of the contracts is described in Note 13 to the Notes to the Consolidated Financial Statements. Two outstanding contracts do not require the Company to purchase minimum annual quantities, but do require the purchase of minimum annual percentages, ranging from 50% to 80% of the respective plants’ requirements for the specified raw materials. One outstanding contract requires the Company to purchase a minimum annual quantity of material. The Company also has entered into a supply agreement for its Millen plant that will become effective upon the commencement of operations at the plant and requires the purchase of a minimum annual percentage of 50% of the Millen plant’s requirements of kaolin.

The Company’s major market risk exposure is to foreign currency fluctuations that could impact its investments in China and Russia. As of December 31, 2012, the Company’s net investment that is subject to foreign currency fluctuations totaled $93.1 million, and the Company has recorded a cumulative foreign currency translation loss of $1.9 million, net of deferred income tax benefit. This cumulative translation loss is included in Accumulated Other Comprehensive Loss. From time to time, the Company may enter into forward foreign exchange contracts to hedge the impact of foreign currency fluctuations. There were no such foreign exchange contracts outstanding at December 31, 2012.

The Company has a $25.0 million revolving credit agreement with a bank. Under the terms of the agreement, the Company has the option of choosing either the bank’s fluctuating Base Rate or LIBOR Fixed Rate, plus an Applicable Margin, all as defined in the credit agreement. There were no borrowings outstanding under the agreement at December 31, 2012. The Company does not believe that it has any material exposure to market risk associated with interest rates.

The Company is subject to the risk of market price fluctuations of certain commodities, such as natural gas, and utilizes forward purchase contracts to manage or reduce market risks relating to these costs. The Company

does not enter into these transactions for speculative or trading purposes. The Company expects to take delivery of the underlying natural gas and, as such, does not currently believe the market risk exposure on these instruments to be material. As of December 31, 2012, $75.3 million of natural gas forward contracts were outstanding for delivery of gas through 2017.

KNOW ALL PERSONS BY THESE PRESENTS, that each person whose signature appears below constitutes and appoints Gary A. Kolstad and Ernesto Bautista III, jointly and severally, his attorneys-in-fact, each with the power of substitution, for him in any and all capacities, to sign any amendments to this Report on Form 10-K, and to file the same, with exhibits thereto and other documents in connection therewith, with the Securities and Exchange Commission, hereby ratifying and confirming all that each of said attorneys-in-fact, or his substitute or substitutes, may do or cause to be done by virtue hereof.

Pursuant to the requirements of the Securities Exchange Act of 1934, this Report has been signed below by the following persons on behalf of the Registrant and in the capacities and on the dates indicated.

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 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, 2012. 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. Based on its assessment and those criteria, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2012.

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.

We have audited CARBO Ceramics Inc.’s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). CARBO Ceramics Inc.’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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.

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.

In our opinion, CARBO Ceramics Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CARBO Ceramics Inc. as of December 31, 2012, and 2011, and the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012 and our report dated February 25, 2013 expressed an unqualified opinion thereon.

We have audited the accompanying consolidated balance sheets of CARBO Ceramics Inc. as of December 31, 2012 and 2011, and the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2012. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CARBO Ceramics Inc. at December 31, 2012 and 2011, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2012, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), CARBO Ceramics Inc.’s internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2013 expressed an unqualified opinion thereon.

CARBO Ceramics Inc. (the “Company”) was formed in 1987 and is a manufacturer of ceramic proppants. During 2010, the Company began production of resin-coated ceramic and resin-coated sand proppants. The Company has six production plants in: New Iberia, Louisiana; Eufaula, Alabama; McIntyre, Georgia; Toomsboro, Georgia; Luoyang, China; and Kopeysk, Russia. The Company predominantly markets its proppant products through pumping service companies that perform hydraulic fracturing for oil and gas companies. Finished goods inventories are stored at the plant sites and various domestic and international remote distribution facilities. The Company also provides the industry’s most popular 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. The Company wound-down its geotechnical monitoring business in late 2012.

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

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. 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, 2012 and 2011 was $1,844 and $1,933, respectively. Other receivables were $1,732 and $1,968 as of December 31, 2012 and 2011, respectively, of which 2012 related mainly to miscellaneous receivables in the United States and China. Other receivables for 2011 related mainly to miscellaneous receivables in the United States and China and value added tax receivables in Russia and China.

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.

Inventories are stated at the lower of cost (weighted average) or market. 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.

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:

The Company holds approximately 4,150 acres of land and leasehold interests containing kaolin reserves near its plants in Georgia and Alabama. The Company also holds approximately 490 acres of land and leasehold interests near its resin-coating facility currently under construction in Marshfield, Wisconsin containing sand reserves for use as raw material in the production of its resin-coated sand products. 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.

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. During 2012, 2011 and 2010, the Company recognized losses of $518, $1,548 and $1,449, respectively, on disposal or impairment of various assets. The loss in 2012 consisted primarily of the wind down of the geotechnical monitoring business. The loss in 2011 consisted of an impairment of goodwill related to the Company’s geotechnical monitoring business, a write-down of a 6% interest in an investment accounted for under the cost method as a result of the sale of the business by majority shareholders and certain equipment disposals. The loss in 2010 consisted of an impairment of goodwill related to the Company’s geotechnical monitoring business and equipment disposals.

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, not to exceed five years.

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 as well as when an event, or change in circumstances, indicates an impairment is more likely than not to have occurred. As a result of changes in business conditions in the geotechnical monitoring business during 2011 and 2010, the Company recorded an impairment charge of $889 and $470, respectively, on goodwill associated with that reporting unit. The latest impairment review indicated goodwill related to other reporting units was not impaired.

Revenue from proppant sales is recognized when title passes to the customer, generally upon delivery. Revenue from consulting and geotechnical services 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 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.

Start-up activities, including organization costs, are expensed as incurred. Start-up costs for 2012 primarily related to the start-up of the second resin-coating line at the Company’s New Iberia, Louisiana facility.

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 are charged to operations when incurred and are included in Selling, General and Administrative expenses. The amounts incurred in 2012, 2011 and 2010 were $6,916, $7,335 and $5,279, respectively.

Financial statements of the Company’s foreign subsidiaries are translated using current exchange rates for assets and liabilities; average exchange rates for the period for revenues, expenses, gains and losses; and historical exchange rates for equity accounts. Resulting translation adjustments are included in, and the only component of, Accumulated Other Comprehensive Loss as a separate component of shareholders’ equity.

In July 2012, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2012-02, “Intangibles — Goodwill and Other (ASC Topic 350),” (“ASU 2012-02”). This accounting update allows entities to perform a qualitative assessment on intangible assets impairment to determine whether it is more likely than not (defined as having a likelihood of more than 50 percent) that the intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test by comparing the fair value with the carrying amount. This guidance is effective for intangible assets impairment tests performed in interim and

annual periods for fiscal years beginning after September 15, 2012. The Company does not expect the adoption of this guidance to have a material impact on the Company’s financial position, results of operations or cash flows.

In September 2011, the FASB issued updated authoritative guidance on goodwill impairment. This update allows for entities to perform a qualitative assessment on goodwill impairment to determine whether it is more likely than not (defined as having a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

In June 2011, the FASB issued updated authoritative guidance on the presentation of comprehensive income. This update requires the presentation of the components of net income and other comprehensive income either in a single continuous statement or in two separate but consecutive statements. The requirement to present reclassification adjustments for items that are reclassified from other comprehensive income to net income on the face of the financial statement has been deferred by the FASB. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows. Net income and other comprehensive income has been presented in two separate but consecutive statements for the current reporting period and prior comparative periods in the consolidated financial statements.

In December 2010, the FASB issued authoritative guidance on application of the goodwill impairment model when a reporting unit has a zero or negative carrying amount. When a reporting unit has a zero or negative carrying value, Step 2 of the goodwill impairment test should be performed if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. The guidance is effective for the Company beginning in the first quarter of fiscal 2012. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

In December 2010, the FASB issued authoritative guidance on disclosure of supplementary pro forma information for business combinations. The new guidance requires that pro forma financial information should be prepared as if the business combination occurred as of the beginning of the prior annual period. The guidance is effective for the Company for business combinations with acquisition dates occurring in and from the first quarter of fiscal 2012. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

Amortization expense for 2012, 2011 and 2010 was $1,224, $1,131 and $1,043, respectively. Estimated amortization expense for each of the ensuing years through December 31, 2017 is $1,117, $1,105, $1,030, $784 and $638, respectively.

Bauxite raw materials are used in the production of heavyweight ceramic products. As of December 31, 2012 and 2011, the Company has classified as long-term assets those bauxite raw materials inventories and prepayments in the United States that are not expected to be consumed in production during the upcoming twelve month period.

The Company has an unsecured revolving credit agreement with a bank. On March 5, 2012, the Company entered into a first amendment to this credit agreement to (i) extend its maturity date from January 29, 2013 to July 29, 2013, (ii) increase the size from $10,000 to $25,000, and (iii) make other administrative changes to certain covenants and provisions. The Company has the option of choosing either the bank’s fluctuating Base Rate or LIBOR Fixed Rate, plus an Applicable Margin, all as defined in the credit agreement. The terms of the credit agreement provide for certain affirmative and negative covenants and require the Company to maintain certain financial ratios. Commitment fees are payable quarterly at the annual rate of 0.50% of the unused line of credit. Commitment fees for 2012, 2011 and 2010 were $107, $51 and $47, respectively.

The Company leases certain property, plant and equipment under operating leases, primarily consisting of railroad equipment leases. Minimum future rental payments due under non-cancelable operating leases with remaining terms in excess of one year as of December 31, 2012 are as follows:

Leases of railroad equipment generally provide for renewal options at their fair rental value at the time of renewal. In the normal course of business, operating leases for railroad equipment are generally renewed or replaced by other leases. Rent expense for all operating leases was $21,452 in 2012, $11,590 in 2011 and $9,054 in 2010.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities as of December 31 are as follows:

Foreign earnings in the table above are presented net of foreign tax credits of $4,432 and $3,868 as of December 31, 2012 and 2011, respectively, which are expected to be utilized upon repatriation of the foreign earnings.

Significant components of the provision for income taxes for the years ended December 31 are as follows:

Provision has been made for deferred U.S. income taxes on all foreign earnings based on the Company’s intent to repatriate foreign earnings. The reconciliation of income taxes computed at the U.S. statutory tax rate to the Company’s income tax expense for the years ended December 31 is as follows:

The Company had a recorded reserve of $227 associated with uncertain tax positions as of December 31, 2012 and there were no significant changes to the recorded reserve during 2012. If these uncertain tax positions are recognized, substantially all of this amount would impact the effective tax rate. Related accrued interest and penalties are recorded in income tax expense and are not material.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates, the most significant of which are U.S. federal and certain state jurisdictions. The Company does not currently have material income tax exposure in foreign jurisdictions due to tax holidays, recent commencement of operations or immaterial operations. The 2009 and subsequent tax years are still subject to examination. Various U.S. state jurisdiction tax years remain open to examination as well though the Company believes assessments, if any, would be immaterial to its consolidated financial statements.

The Company’s charter authorizes 5,000 shares of Preferred Stock. The Board of Directors has the authority to issue Preferred Stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the Company’s shareholders.

On February 13, 2002, the Company adopted a shareholder rights plan and declared a dividend of one right for each outstanding share of Common Stock to shareholders of record on February 25, 2002. With certain exceptions, the rights become exercisable if a tender offer for the Company is announced or any person or group acquires beneficial ownership of at least 15 percent of the Company’s Common Stock. If exercisable, each right entitles the holder to purchase one fifteen-thousandth of a share of Series A Preferred Stock at an exercise price of $133 and, if any person or group acquires beneficial ownership of at least 15 percent of the Company’s Common Stock, to acquire a number of shares of Common Stock having a market value of two times the $133 exercise price.
