The accompanying unaudited consolidated financial statements of CARBO Ceramics Inc. have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. The results of the interim periods presented herein are not necessarily indicative of the results to be expected for any other interim period or the full year. The consolidated balance sheet as of December 31, 2014 has been derived from the audited financial statements at that date. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2014 included in the annual report on Form 10-K of CARBO Ceramics Inc. for the year ended December 31, 2014.

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

In late 2014 and early 2015, a severe decline in oil and natural gas prices led to a significant decline in oil and natural gas industry drilling activities and capital spending. During the three month period ended March 31, 2015, the Company implemented a number of initiatives to preserve cash and lower costs, including: reducing workforce across the organization, lowering production output levels in order to align with lower demand, limiting capital expenditures and reducing dividends. As a result of these measures, the Company temporarily idled production and furloughed employees at the Toomsboro and Millen, Georgia manufacturing plants for approximately 90 days and mothballed the manufacturing plants in McIntyre, Georgia and Luoyang, China. Production resumed at both of the temporarily idled facilities during the second quarter of 2015.

In general, temporarily idled facilities are expected to remain closed for a short period of time, generally less than one year. Mothballed facilities are expected to remain closed for one year or longer. The accounting treatment is the same for both temporarily idled and mothballed facilities, except that mothballed assets are evaluated for possible impairment while temporarily idled assets are not necessarily assessed for impairment. The Company continues to depreciate both temporarily idled and mothballed assets.

The facility in Toomsboro, Georgia is the Company’s largest manufacturing facility consisting of four production lines. During the third quarter of 2015, one of the four manufacturing lines at the Toomsboro plant ran the entire quarter, while a second line ran part of the quarter. Production levels at the Millen, Georgia and Eufaula, Alabama facilities were near the stated capacity of those facilities. However, the Company expects to temporarily idle the Millen, Georgia facility during the fourth quarter of 2015. The mothballed plants in McIntyre, Georgia and Luoyang, China remained closed.

During the three-month period ended March 31, 2015, the Company reviewed the carrying values of all inventories and concluded that certain inventories in China had been impacted by changes in market conditions. Current market prices had fallen below carrying costs for certain inventories. Consequently, the Company recognized a $3,887 loss in cost of sales, to adjust finished goods and raw materials carrying values to the lower market prices on inventories inside China. The adjustments were based on current market prices for these or similar products, as determined by actual sales, bids, and/or quotes from third parties. The Company again reviewed the carrying values of all inventories as of June 30, 2015 and September 30, 2015 and concluded that no further adjustments were warranted as of those times. In addition, during the three month period ended March 31, 2015, the Company recognized a $485 loss in cost of sales as a result of other inventory adjustments unrelated to lower of cost or market issues.

As a result of the Company substantially reducing manufacturing production levels, including by idling and mothballing certain facilities, the component of the Company’s accounting policy for inventory relating to operating at production levels below normal capacity was triggered and resulted in certain production costs being expensed instead of being capitalized into inventory. Under this policy, the Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. The Company expensed $25,157 in production costs during the nine month period ended September 30, 2015. There were no such costs in the prior year period.

As noted, the Company plans to idle production at the Millen, Georgia manufacturing facility during the fourth quarter of 2015. The Company does not necessarily assess temporarily idled assets for impairment unless events or circumstances indicate their carrying amounts might not be recoverable. Short-term stoppages of production for less than one year do not necessarily significantly impact the long-term expected cash flows of the idled facility. As of September 30, 2015, the Company did not assess the Millen plant for impairment. However, the Company continues to monitor market conditions closely and, during the fourth quarter of 2015, expects to collect additional information regarding customers’ 2016 drilling plans and budgets that could affect future production plans for the Company’s Millen, Georgia and other manufacturing facilities. Further deterioration of market conditions could result in impairment charges being taken on these and/or other long-lived assets, including the Company’s manufacturing plants, goodwill and intangible assets. The Company will evaluate long-lived assets for impairment at such time that events or circumstances indicate that carrying amounts might be impaired.

The following table sets forth the computation of basic and diluted (loss) earnings per share under the two-class method:

On January 28, 2015, 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. As of September 30, 2015, the Company had not repurchased any shares under the plan.

On July 21, 2015, the Board of Directors declared a cash dividend of $0.10 per common share payable to shareholders of record on August 3, 2015. The dividend was paid on August 17, 2015. On September 22, 2015, the Board of Directors declared a cash dividend of $0.10 per common share payable to shareholders of record on November 2, 2015. This dividend is payable on November 16, 2015.

Natural gas is used to fire the kilns at the Company’s domestic manufacturing plants. In an effort to mitigate potential volatility in the cost of natural gas purchases and reduce exposure to short-term spikes in the price of this commodity, from time to time, the Company enters into contracts to purchase a portion of the anticipated monthly natural gas requirements at specified prices. Contracts are geographic by plant location. Historically, the Company has taken delivery of all natural gas quantities under contract, which exempted the Company from accounting for the contracts as derivative instruments. However, due to the severe decline in industry activity in early 2015, the Company significantly reduced production levels and consequently did not take delivery of all of the contracted natural gas quantities. As a result, the Company began to account for relevant contracts as derivative instruments.

Derivative accounting requires the natural gas contracts to be recognized as either assets or liabilities at fair value with an offsetting entry in earnings. The Company uses the income approach in determining the fair value of these derivative instruments. The model used considers the difference, as of each balance sheet date, between the contracted prices and the New York Mercantile Exchange (“NYMEX”) forward strip price for each contracted period. The estimated cash flows from these contracts are discounted using a discount rate of 5.5%, which reflects the nature of the contracts as well as the timing and risk of estimated cash flows associated with the contracts. The discount rate had an immaterial impact on the fair value of the contracts for the nine months ended September 30, 2015. The last natural gas contract will expire in December 2018. As a result, during the nine months ended September 30, 2015, the Company recognized a loss on derivative instruments of $14,259 in cost of sales. The cumulative present value of the losses on these natural gas derivative contracts as of September 30, 2015 are presented as current and long-term liabilities, as applicable, in the Consolidated Balance Sheet.

At September 30, 2015, the Company has contracted for delivery a total of 9,000,000 MMBtu of natural gas at an average price of $4.53 per MMBtu through December 31, 2018. Contracts covering 7,560,000 MMBtu are subject to accounting as derivative instruments. Future decreases in the NYMEX forward strip prices will result in additional derivative losses while future increases in the NYMEX forward strip prices will result in derivative gains. Future gains or losses will approximate the change in NYMEX natural gas prices relative to the total quantity of natural gas under contracts now subject to accounting as derivatives. The historical average NYMEX natural gas contract settlement prices for the quarters ended September 30, 2015 and 2014 were $2.77 per MMBtu and $4.06 per MMBtu, respectively.

The Company’s derivative instruments are measured at fair value on a recurring basis. U.S. GAAP establishes a fair value hierarchy that has three levels based on the reliability of the inputs used to determine the fair value. These levels include: Level 1, defined as inputs such as unadjusted quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for use when little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company’s natural gas derivative instruments are included within the Level 2 fair value hierarchy. The following table sets forth by level within the fair value hierarchy the Company’s assets and liabilities that were accounted for at fair value:

The 2014 CARBO Ceramics Inc. Omnibus Incentive Plan (the “2014 Omnibus Incentive Plan”) provides for granting of cash-based awards, stock options (both non-qualified and incentive) and other equity-based awards (including stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares, deferred share units or share-denominated performance units) to employees and non-employee directors. As of September 30, 2015, 520,303 shares were available for issuance under the 2014 Omnibus Incentive Plan. Although the 2009 CARBO Ceramics Inc. Omnibus Incentive Plan (the “2009 Omnibus Incentive Plan”) has expired, certain nonvested restricted shares granted under that plan remain outstanding in accordance with its terms. Additionally, certain units of phantom stock remain outstanding under the 2009 Omnibus Incentive Plan, as described below.

A summary of restricted stock activity and related information for the nine months ended September 30, 2015 is presented below:

As of September 30, 2015, there was $9,759 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under both the expired 2009 Omnibus Incentive Plan and the 2014 Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 2.0 years. The total fair value of shares vested during the nine months ended September 30, 2015 was $6,417.

The Company made market-based cash awards to certain executives of the Company pursuant to the 2014 Omnibus Incentive Plan with a total Target Award of $753, as of September 30, 2015. The amount of awards that will ultimately vest can range from 0% to 200% based on the Company’s Relative Total Shareholder Return calculated over a three year period beginning January 1, 2015 through December 31, 2017.

The Company also made phantom stock awards to key international employees pursuant to the expired 2009 Omnibus Incentive Plan prior to its expiration and pursuant to the 2014 Omnibus Incentive Plan. The units subject to a phantom stock award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom stock are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued with regard to outstanding phantom stock awards. As of September 30, 2015, there were 18,180 units of phantom stock granted under the expired 2009 Omnibus Incentive Plan, of which 12,569 have vested and 2,590 have been forfeited. As of September 30, 2015, there were 5,020 units of phantom stock granted under the 2014 Omnibus Incentive Plan, of which none have vested and none have been forfeited. As of September 30, 2015, nonvested units of phantom stock under the 2009 Omnibus Incentive Plan and the 2014 Omnibus Incentive Plan have a total value of $153, a portion of which is accrued as a liability within Accrued Payroll and Benefits.

The Company has a revolving credit agreement with a bank. On July 27, 2015, the Company entered into a fourth amendment to this credit facility that, among other items, (i) reduced the size of the revolving credit facility from $100,000 to $90,000; (ii) secures borrowings with a blanket lien on substantially all of the Company’s accounts receivable and inventories; (iii) prohibits the Company from granting security interests in the Company’s fixed assets and real property; (iv) sets interest at LIBOR plus 4.00%; (v) sets the maturity date as December 31, 2018; and (vi) waives compliance with the maximum leverage ratio and fixed charge ratio covenants through December 31, 2016. Additionally, the fourth amendment added covenants which (i) requires a minimum assets coverage ratio of 1.25 to 1.0 calculated on a monthly basis and (ii) limits capital expenditures to $65,000 annually through December 31, 2016, subject to maintaining pro forma liquidity of $15,000. The terms of the credit agreement provide for certain affirmative and negative covenants and require the Company

to maintain certain financial ratios. As of September 30, 2015, the Company’s outstanding debt under the credit agreement was $88,000 and the weighted average interest rate was 4.54% based on LIBOR-based rate borrowings.

As of September 30, 2015, the Company’s net investment that is subject to foreign currency fluctuations totaled $25,031, and the Company has recorded a cumulative foreign currency translation loss of $26,694. This cumulative translation loss is included in, and is the only component of, Accumulated Other Comprehensive Loss. There were no amounts reclassified to net income during the nine-months ended September 30, 2015. During 2014 and continuing into 2015, the value of the Russian Ruble significantly declined relative to the U.S. dollar. The financial impact of this decline on the Company’s net assets in Russia is included in Other Comprehensive Income and the cumulative foreign currency translation loss noted above. No income tax benefits have been recorded on these losses as a result of the uncertainty about recoverability of the related deferred income tax benefits.

In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date,” which revises the effective date of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”) to interim and annual periods beginning after December 15, 2017 with early adoption permitted no earlier than interim and annual periods beginning after December 15, 2016. In May 2014, the FASB issued ASU No. 2014-09, which amends current revenue guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is currently evaluating the potential impact, if any, of adopting this new guidance on the consolidated financial statements and related disclosures.

In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330),” (“ASU 2015-11”) which amends and simplifies the measurement of inventory. The main provisions of the standard require that inventory be measured at the lower of cost and net realizable value. Prior to the issuance of the standard, inventory was measured at the lower of cost or market (where market was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin). ASU 2015-11 will be effective for the interim and annual periods beginning after December 15, 2016 with early adoption permitted. The Company is currently evaluating the potential impact, if any, of adopting this new guidance on the consolidated financial statements and related disclosures.

In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30),” (“ASU 2015-03”) which amends and simplifies the presentation of debt issuance costs. The main provisions of the standard require that debt issuance costs related to a recognized liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, and amortization of the debt issuance costs must be reported as interest expense. ASU 2015-03 will be effective for the interim and annual periods beginning after December 15, 2015 with early adoption permitted. The new standard must be applied on a retroactive basis, and the Company will be required to comply with the applicable disclosures for a change in accounting principle. The adoption of ASU 2015-03 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

The Company is subject to legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CARBO Ceramics Inc. (“we,” “us,” “our” or our “Company”) is an oilfield services technology company that generates revenue primarily through the sale of production enhancement products and services to the oil and natural gas industry. Our principal business consists of manufacturing and selling proppant products for use primarily in the hydraulic fracturing of oil and natural gas wells. These proppant products include ceramic, resin-coated proppants and raw frac sand. We also provide the industry’s most widely used hydraulic fracture simulation software, FracPro®, as well as hydraulic fracture design and consulting services. In addition, we provide a broad range of technologies for spill prevention, containment and countermeasures.

Our products and services help oil and natural gas producers increase production and recovery rates from their wells, thereby lowering overall finding and development costs. As a result, our business is dependent to a large extent on the level of drilling and hydraulic fracturing activity in the oil and natural gas industry worldwide. Gross margin for our ceramic proppant business is principally impacted by sales volume, product mix, sales price, distribution costs, manufacturing costs, including natural gas, and our production levels as a percentage of our capacity.

In 2013, we began selling raw frac sand. Raw frac sand products sell at much lower prices and with lower gross margins than our ceramic proppant. While gross (loss) profit is generally not materially impacted by the sale of these products, given the level of sales volumes of raw frac sand compared to ceramic proppant, our overall gross margin as a percent of revenues and the overall selling price for our proppants can be impacted. In 2014, our gross margin was also impacted by spending on the development of our new KRYPTOSPHERE^TM proppant technology and preparations for its commercialization.

In June 2014, we completed the first proppant production line at our new Millen, Georgia facility. In addition, during 2014, we began construction of a second production line in Millen, Georgia. Due to current market conditions, completion of the second line at the manufacturing facility in Millen, Georgia has been temporarily suspended. As of September 30, 2015, the value of the temporarily suspended assets relating to the second production line at Millen totaled approximately 44% of the Company’s total construction in progress and we estimate that the second line is approximately 90% complete. The Company currently does not expect to complete construction of the second production line and commence production until market conditions improve so as to warrant production by a second production line at this facility. Further, we expect to idle the Millen, Georgia facility during the fourth quarter of 2015. The retrofit of the first phase of an existing plant to produce KRYPTOSPHERE is substantially complete and commissioning will be finalized during the fourth quarter of 2015. We have decided to defer completing the second phase of the retrofit until market conditions warrant moving forward with the project. As of September 30, 2015, the value of the temporarily suspended assets relating to the second phase of the retrofit totaled approximately 11% of the Company’s total construction in progress and we estimate that the second phase is approximately 80% complete.

In late 2014 and early 2015, a severe decline in oil and natural gas prices led to a significant decline in oil and natural gas industry drilling activities and capital spending. We expect that these low oil and natural gas prices will continue for the foreseeable future and will continue to negatively impact both pricing and demand for proppant. During the third quarter of 2015, the average price of West Texas Intermediate (“WTI”) crude oil fell 53% to $46.42 per barrel compared to $97.78 per barrel in the third quarter of 2014. The average United States rig count fell 54% in the third quarter of 2015 to 866 rigs compared to 1,903 rigs in the third quarter of 2014. In addition, exploration and production (“E&P”) operators used a higher percentage of raw frac sand in place of ceramic proppant during the third quarter of 2015 when compared to the same period of 2014. These events, along with an oversupplied ceramic proppant market and low oil and natural gas prices, drove lower average prices for our proppants during the third quarter of 2015, when compared with the same period of 2014.

Beginning in the first quarter of 2015, we implemented a number of initiatives to preserve cash and lower costs, including: reducing workforce across our organization, lowering our production output levels in order to align with lower demand, limiting capital expenditures and reducing dividends. As a result of these measures, in the United States, during the first quarter of 2015, we idled production (including furloughing employees) at the Toomsboro and Millen, Georgia manufacturing plants for approximately 90 days and mothballed our

manufacturing plant in McIntyre, Georgia. During the second quarter of 2015, production resumed at both of the temporarily idled facilities. During the third quarter of 2015, one of the four manufacturing lines at the Toomsboro, Georgia plant ran the entire quarter while a second line ran part of the quarter. Production levels at the Millen, Georgia and Eufaula, Alabama facilities were near stated capacities of those facilities. However, we expect to idle the Millen, Georgia facility during the fourth quarter of 2015. In the event that the market demand for proppants further decreases, we may further reduce operations at our active manufacturing plants.

Furthermore, conditions in the North American oil and natural gas market also negatively impacted the proppant market inside China. Proppant manufacturers in China experienced excess production capacity due to market conditions in North America. As a result, we recognized an impairment charge on our long-lived assets in China and wrote down the value of certain inventories in China down to lower market prices during the second half of 2014, and further wrote down the value of certain of our finished goods and raw materials in China down to lower market prices during the first quarter of 2015. As of September 30, 2015, the value of our inventories inside China totaled $4.1 million. We mothballed our plant in China during the first quarter of 2015 and do not expect to resume operations at this facility in the foreseeable future. We are actively working to sell remaining inventories in China. While production activities ceased and production related employees have been terminated, we continue to retain sales, logistics, and administrative staff in China. Upon substantial liquidation of our China entity, we will recognize a non-cash gain from realizing our China-related cumulative foreign currency translation adjustment (“CTA”). We are still evaluating alternatives for the possible disposition of these China assets, and we intend to hold these assets until this evaluation is complete. As of September 30, 2015, the China-related CTA had an unrealized gain of $8.9 million.

Although most direct manufacturing costs have been relatively stable or predictable over time, the cost of natural gas, which is used in production by our domestic manufacturing facilities, is subject to volatility. In an effort to mitigate potential volatility in the cost of natural gas purchases and reduce exposure to short-term spikes in the price of this commodity, from time to time, we enter into natural gas contracts to purchase a portion of the anticipated monthly natural gas requirements at specified prices. Due to the severe decline in industry activity early in 2015, we reduced our level of proppant production and did not take delivery of all of the contracted natural gas quantities. As a result, we began to account for relevant contracts as derivative instruments and have recorded a loss on these contracts of $14.3 million for the nine month period ended September 30, 2015.

The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, which require us to make estimates and assumptions (see Note 1 to the consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2014). We believe that some of our accounting policies involve a higher degree of judgment and complexity than others. As of December 31, 2014, our critical accounting policies included revenue recognition, estimating the recoverability of accounts receivable, inventory valuation, accounting for income taxes and accounting for long-lived assets. These critical accounting policies are discussed more fully in our annual report on Form 10-K for the year ended December 31, 2014.

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. During the first quarter of 2015, we temporarily idled production and furloughed employees at our Toomsboro and Millen, Georgia manufacturing plants (both for approximately 90 days) and mothballed our manufacturing plants in McIntyre, Georgia and Luoyang, China. Temporarily idled facilities are expected to remain closed for a short period of time, generally less than one year. Mothballed facilities are expected to remain closed for one year or longer. The accounting treatment is the same for both temporarily idled and mothballed facilities, except that mothballed assets are evaluated for possible impairment while temporarily idled assets are not necessarily assessed for impairment. In the instances of idling both the Toomsboro and Millen, Georgia plants in early 2015 for approximately 90 days each, we did not assess the temporarily idled assets for impairment because such short-term stoppages of production were designed to temporarily reduce inventory levels and as such did not significantly impact the long-term expected cash flows of the plants. We continue to depreciate both temporarily idled and mothballed assets.

At the time the manufacturing facility in McIntyre, Georgia was mothballed, we conducted an interim impairment analysis of the related long-lived assets. Key assumptions used in the analysis included: 1) the plant would remain closed for two years; 2) in year 3 production would start-up at 50% of capacity and thereafter

return to production levels within normal capacity; and 3) market pricing would be similar to lower 2015 levels, thus conservatively reducing expected gross profit and thus cash flows. Pursuant to that analysis, we determined that the projected gross cash flows attributable to the facility substantially exceed the carrying value of each of the assets; therefore, as of the date of that analysis, we concluded that there was no impairment and further that impairment would not be reasonably possible in the near term. At the time the manufacturing facility was mothballed in Luoyang, China, we did not conduct an interim impairment analysis because an impairment charge was recorded in 2014 that reduced the value of the related long-lived assets to net salvage value, which approximates fair value.

During the quarter ended March 31, 2015, we identified an existing accounting policy as critical related to the accounting for derivative instruments as a result of not taking delivery of all of our contracted natural gas quantities. We began accounting for relevant natural gas contracts as derivative instruments, which requires us to recognize the gas contracts as either assets or liabilities at fair value with an offsetting entry in earnings. We use the income approach in determining the fair value of our derivative instruments. The model used considers the difference, as of each balance sheet date, between the contracted prices and the New York Mercantile Exchange (“NYMEX”) forward strip price for each contracted period. The estimated cash flows from these contracts are discounted using a discount rate of 5.5%, which reflects the nature of the contracts as well as the timing and risk of estimated cash flows associated with the contracts. The discount rate had an immaterial impact on the fair value of the contracts for the nine months ended September 30, 2015. The last natural gas contract will expire in December 2018. As of September 30, 2015, gas contracts covering 7,560,000 MMBtu are subject to accounting as derivative instruments. During the nine month period ended September 30, 2015, we recognized a loss on derivative instruments of $14.3 million in cost of sales. Future decreases in the NYMEX forward strip prices will result in additional derivative losses while future increases in the NYMEX forward strip prices will result in derivative gains. Future gains or losses will approximate the change in NYMEX natural gas prices relative to the total quantity of natural gas under contracts subject to accounting as derivatives.

During the quarter ended March 31, 2015, low production levels triggered the component of our inventory accounting policy relating to operating at production levels below normal capacity. Accordingly, we added disclosure of this component of our inventory accounting policy to the critical accounting policies disclosures set forth in our Form 10-Q for that quarter. We expense fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. As a result of low production levels and idled and mothballed facilities, we expensed $25.2 million of production costs during the nine month period ended September 30, 2015.

There have been no other changes during the nine months ended September 30, 2015 in our evaluation of our critical accounting policies since December 31, 2014.

Revenues. Revenues of $75.8 million for the third quarter of 2015 decreased 51% compared to $155.4 million for the same period in 2014. The decrease was mainly attributable to a decrease in proppant sales volumes and market-driven reductions in the average selling prices. The decline in ceramic sales volume was largely attributable to a depressed commodity price for oil and the resulting negative impact on industry activity levels. Our worldwide proppant sales volumes and average selling price per pound in the third quarter of 2015 compared to the same period in 2014 were as follows:

North American (defined as Canada and U.S.) proppant sales volume decreased 43% in the three months ended September 30, 2015 compared to the same period in 2014, due in large part to the effect of the declining industry conditions. North American ceramic proppant sales volume decreased 39%. International (excluding Canada) ceramic proppant sales volumes decreased 34%.

Primarily due to the change in product mix and an 18% decline in the average selling price of ceramic proppant, the average selling price per pound of all proppant was $0.17 during the third quarter of 2015 compared to $0.20 for the same period in 2014. In addition to product mix, average selling prices can be impacted by sales prices, geographic areas of sale, customer requirements and delivery methods.

Gross (Loss) Profit. Gross loss for the third quarter of 2015 was $4.6 million, or 6% of revenues, compared to gross profit of $42.2 million, or 27% of revenues, for the same period in 2014. The decrease in gross (loss) profit was primarily the result of lower ceramic proppant sales volumes and a decrease in the average selling price of ceramic proppant. In addition, we expensed $5.5 million in production costs as a result of low production levels and idled and mothballed facilities. We expect to incur these types of expenses in the future until our production levels return to normal capacity. Gross (loss) profit was further reduced by a $1.7 million loss on natural gas derivative instruments and $1.0 million in severance costs incurred as a result of the reduction in workforce.

Selling, General and Administrative (SG&A) and Other Operating Expenses. SG&A expenses totaled $14.6 million for the third quarter of 2015 compared to $18.1 million for the same period in 2014. The decrease in SG&A expenses is largely attributable to cost cutting measures implemented in early 2015 and throughout the year. As a percentage of revenues, SG&A expenses increased to 19.3% in the third quarter of 2015 compared to 11.6% for the same period in 2014, primarily due to the decrease in revenues. While we took actions in 2015 to reduce our cost base, the cost savings from these actions were partially offset by $0.6 million in SG&A related severance costs in the third quarter of 2015. Loss on disposal or impairment of assets of $5.1 million in the third quarter of 2014 consisted primarily of an impairment of long-lived assets, and did not reoccur in the third quarter of 2015. During the third quarter of 2014, the Company made a decision that it will not move forward with construction of a resin coating plant in Marshfield, Wisconsin for which the Company had previously developed engineering plans and procured certain equipment that had long-lead delivery times. These assets were classified as available for sale, and with certain other unrelated long-lived assets, the Company recognized a loss from adjusting the carrying value to net realizable value.

Income Tax (Benefit) Expense. Income tax benefit was $5.4 million, or 27.9% of pretax loss, for the third quarter of 2015 compared to income tax expense of $5.3 million, or 27.9% of pretax income, for the same period last year. In 2016, the Company intends to file amended income tax returns for 2013 and possibly 2014 to carry back the total net operating loss sustained during 2015. Consequently, as of September 30, 2015, the expected amount of prior year income tax payments expected to be refunded in 2016 is included as a current asset in Deferred Income Taxes.

Revenues. Revenues of $222.8 million for the nine months ended September 30, 2015 decreased 54% compared to $480.5 million for the same period in 2014. The decrease was mainly attributable to a decrease in ceramic proppant and resin coated sand sales volumes, in conjunction with market-driven reductions in the average selling prices. The decline in ceramic sales volume was largely attributable to a depressed commodity price for oil and the resulting negative impact on industry activity levels, along with an increased number of E&P operators using a higher percentage of raw frac sand as an alternative to proppant due to its lower cost. Our worldwide proppant sales volumes and average selling price per pound for the nine months ended September 30, 2015 compared to the same period in 2014 were as follows:

North American (defined as Canada and U.S.) proppant sales volume decreased 31% in the nine months ended September 30, 2015 compared to the same period in 2014, due in large part to the effect of the declining industry conditions on sales of ceramic proppant and resin coated sand. North American ceramic proppant sales volume decreased 53%. International (excluding Canada) ceramic proppant sales volumes decreased 30%.

Primarily due to the change in product mix and a 15% decline in the average selling price of ceramic proppant, the average selling price per pound of all proppant was $0.14 during the nine months ended September 30, 2015 compared to $0.22 for the same period in 2014. In addition to product mix, average selling prices can be impacted by sales prices, geographic areas of sale, customer requirements and delivery methods.

Gross (Loss) Profit. Gross loss for the nine months ended September 30, 2015 was $40.9 million, or 18% of revenues, compared to gross profit of $140.2 million, or 29% of revenues, for the same period in 2014. The decrease in gross (loss) profit was primarily the result of lower ceramic proppant sales volumes and a decrease in the average selling price of ceramic proppant. In addition, we recorded a $14.3 million loss on natural gas derivative instruments, and expensed $25.2 million in production costs as a result of low production levels and idled and mothballed facilities. We expect to incur these types of expenses in the future until our production levels return to normal capacity. Gross (loss) profit was further reduced by $5.8 million in severance costs incurred as a result of the reductions in workforce and $4.4 million of adjustments in cost of sales, primarily to reduce the value of certain inventories down to lower market prices on inventories in China during the first quarter of 2015.

Selling, General and Administrative (SG&A) and Other Operating Expenses, and Start-up Costs. SG&A expenses totaled $45.9 million for the nine months ended September 30, 2015 compared to $54.0 million for the same period in 2014. As a percentage of revenues, SG&A expenses increased to 20.6% in the nine months ended September 30, 2015 compared to 11.2% for the same period in 2014, primarily due to the decrease in revenues. While we took actions in 2015 to reduce our cost base, the cost savings from these actions were partially offset by $2.1 million in SG&A related severance costs. Start-up costs of $0.8 million in the nine months ended September 30, 2014 related to the start-up of the first production line at the new manufacturing facility in Millen, Georgia. Loss on disposal or impairment of assets of $4.9 million in 2014 consisted primarily of an impairment of long-lived assets. The Company made a decision that it will not move forward with construction of a resin coating plant in Marshfield, Wisconsin for which the Company had previously developed engineering plans and procured certain equipment that had long-lead delivery times. These assets were classified as available for sale, and with certain other unrelated long-lived assets, the Company recognized a loss in adjusting the carrying value to net realizable value.

Income Tax (Benefit) Expense. Income tax benefit was $27.3 million, or 31.5% of pretax loss, for the nine months ended September 30, 2015 compared to income tax expense of $25.7 million, or 31.8% of pretax income, for the same period last year.

During 2015, we have taken significant steps to reduce future costs and align production levels with lower customer demands resulting from the severe decline in the oil and natural gas industry. The timing and magnitude of an industry recovery is uncertain. The typical cost-cutting reaction by E&P operators has been significant, as evidenced by the sharp reduction in industry activity. The impact on the entire ceramic proppant industry has been severe, leading other domestic proppant suppliers to make similar decisions to mothball and idle ceramic proppant manufacturing capacity. While U.S. imports of ceramic proppant have declined significantly compared to 2014, we believe that inventory levels of low quality imported ceramic proppant in the U.S. may still be at levels that keep pressure on pricing.

With the oil and natural gas industry remaining severely depressed, near term visibility for ceramic proppant demand is limited. Many E&P operators’ borrowing bases are being reduced by banks and some E&P operators are stopping all completion activity in the fourth quarter of 2015. As a result, our proppant sales volumes in the fourth quarter of 2015 will likely decline significantly when compared to the third quarter of 2015. In addition, we expect to see additional pricing pressure in the fourth quarter of 2015.

With regard to a longer term view, we expect many E&P operators to soon release their drilling and completion plans for 2016. Some have recently released such plans. This information should provide better guidance for 2016 activity. As it appears in the near-term the industry may be headed for a longer downturn than previously expected, we initiated another round of cost reduction efforts across the organization. We continue to address the over-supply situation in the proppant industry by taking capacity offline when necessary. Additional cost reduction efforts could be taken during the fourth quarter of 2015. We will manage through this down-cycle by focusing on cash and cost reduction to preserve financial flexibility. As this strategy includes idling and/or lowering of production output to maintain reduced inventory levels and alignment with market demand, we expect further under-absorption and idling costs to impact our financials in the remainder of 2015. Additionally, we will consider such events and circumstances relative to the carrying values of our long-lived assets, including our manufacturing plants, goodwill and intangible assets. It is possible that further deterioration of market conditions could result in impairment charges being taken on some of these assets.

At September 30, 2015, we had cash and cash equivalents of $90.7 million compared to cash and cash equivalents of $24.3 million at December 31, 2014. During the nine months ended September 30, 2015, we generated $68.1 million of cash from operating activities and borrowed $70.0 million on our line of credit. Uses of cash included $51.3 million for capital expenditures, $12.3 million for the payment of cash dividends, $7.0 million for repayments on our line of credit, and $0.6 million for purchases of our common stock.

Subject to our financial condition, the amount of funds generated from operations, compliance with the covenants under our credit facility and the level of capital expenditures, our current intention is to continue to pay quarterly dividends to holders of our common stock. On September 22, 2015, our Board of Directors approved the payment of a quarterly cash dividend of $0.10 per share to common shareholders as of November 2, 2015. The dividend is payable on November 16, 2015. We estimate that our total capital expenditures for the remainder of 2015 will be between $8.0 million and $13.0 million, which primarily include costs associated with retrofitting an existing plant with the new KRYPTOSPHERE proppant technology.

We maintain a line of credit with a bank. As of September 30, 2015, our outstanding debt under the credit agreement was $88.0 million. As of October 29, 2015, our outstanding debt under the credit agreement was $88.0 million. Depending on the duration and severity of the industry downturn, there is a risk that we may not be in compliance with the asset coverage ratio covenant under the credit agreement in the next 12 months. In the event of non-compliance and if we are unable to secure waivers or modifications to the existing credit agreement or alternative sources of capital, it is possible that we may not have the liquidity sufficient to meet operating expenses, capital expenditures and other cash needs. Given continuing uncertainties with regards to the length of the industry downturn, we are evaluating alternative sources of capital, including modifications to our existing credit arrangement, although there can be no assurance that we will be able to obtain such financing or modifications on favorable terms, or at all.

On July 27, 2015, we entered into a fourth amendment to this credit facility that, among other items, (i) reduced the revolving credit facility from $100.0 million to $90.0 million; (ii) secures borrowings with a blanket lien on substantially all of our accounts receivable and inventories; (iii) prohibits us from granting security interests in

our fixed assets and real property; (iv) sets interest at LIBOR plus 4.00%; (v) sets the maturity date as December 31, 2018; and (vi) waives compliance with the maximum leverage ratio and fixed charge coverage ratio covenants through December 31, 2016. Our line of credit is subject to compliance with the covenants in the underlying amended credit agreement, some of which depend on our future operating performance and cash flow. These factors are in turn subject to prevailing oil and natural gas prices, economic conditions and other factors, many of which are beyond our control.

The following table presents the financial covenants specified in our credit agreement and the actual covenant calculations as of September 30, 2015:

Additional information as to the applicable definitions and requirements of these covenants is contained in the credit agreement. We were in compliance with the financial covenants under our amended credit facility for the quarter ended September 30, 2015. However, there can be no assurance that we will remain in compliance in future quarters and months.

The statements in this Quarterly Report on Form 10-Q that are not historical statements, including statements regarding our future financial and operating performance and liquidity and capital resources, are forward-looking statements within the meaning of the federal securities laws. All forward-looking statements are based on management’s current expectations and estimates, which involve risks and uncertainties that could cause actual results to differ materially from those expressed in forward-looking statements. Among these factors are:

Additional factors that could affect our future results or events are described from time to time in our reports filed with the Securities and Exchange Commission (the “SEC”). Please see the discussion set forth under the caption “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and similar disclosures in subsequently filed reports with the SEC. We assume no obligation to update forward-looking statements, except as required by law.

We are exposed to market risk through foreign currency fluctuations that could impact our investments in China and Russia. As of September 30, 2015, our net investments subject to foreign currency fluctuations totaled $25.0 million and we have recorded cumulative foreign currency translation loss of $26.7 million. This cumulative translation loss is included in Accumulated Other Comprehensive Loss. From time to time, we may enter into forward foreign exchange contracts to hedge the impact of foreign currency fluctuations. There were no such foreign exchange contracts outstanding at September 30, 2015. During 2014 and continuing into 2015, the value of the Russian Ruble significantly declined relative to the U.S. dollar. The financial impact of this decline on our net assets in Russia is included in Other Comprehensive Income and the cumulative foreign currency translation loss noted above. No income tax benefits have been recorded on these losses as a result of the uncertainty about recoverability of the related deferred income tax benefits.

We are also exposed to market risk in the price of natural gas, which is used in production by our domestic manufacturing facilities and is subject to volatility. In an effort to mitigate potential volatility in the cost of natural gas purchases and reduce exposure to short-term spikes in the price of the commodity, from time to time, we enter into contracts to purchase a portion of our anticipated monthly natural gas requirements at specified prices. At September 30, 2015, we have contracted for delivery a total of 9,000,000 MMBtu of natural gas at an average price of $4.53 per MMBtu through December 31, 2018.

Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934 (the “Exchange Act”) is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports filed under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As of September 30, 2015, management carried out an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurances of achieving their control objectives. Based upon and as of the date of that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

There were no changes in the Company’s internal control over financial reporting during the quarter ended September 30, 2015 that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

We are subject to legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position, results of operations, or cash flows.

There have been no material changes to the risk factors discussed in the Annual Report on Form 10-K for the year ended December 31, 2014.

The following table provides information about our repurchases of Common Stock during the quarter ended September 30, 2015:
