Executive Level Overview

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:

• increasing marketing activities globally; and

• focusing on new product development.

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.

General Business Conditions

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.

Critical Accounting Policies

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.

Results of Operations

Net Income



                                         Percent                     Percent
        ($ in thousands)     2012         Change        2011         Change         2010
        Net Income         $ 105,933        (19)%     $ 130,136           65%     $ 78,716

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.

Individual components of financial results are discussed below.

Revenues

                                          Percent                      Percent
   ($ in thousands)          2012         Change          2011         Change          2010
   Consolidated revenues   $ 645,536             3 %    $ 625,705            32 %    $ 473,082

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.

 Consolidated gross profit   $ 223,505         (15)%     $ 261,715            50%     $ 174,671
 As a % of revenues                 35 %                        42 %                         37 %

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.

Selling, General & Administrative (SG&A) and Other Operating Expenses

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.

Income Tax Expense



                                             Percent                     Percent

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.

Outlook

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.

Liquidity and Capital Resources

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 . . .
