3. Common Stock Repurchase Program

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. During the six months ended June 30, 2012, the Company repurchased and retired 60,000 shares at an aggregate price of $5,726. As of June 30, 2012, the Company has repurchased and retired 1,877,576 shares at an aggregate price of $78,301.

On July 17, 2012, the Board of Directors declared a cash dividend of $0.27 per common share payable to shareholders of record on August 1, 2012. This dividend is payable on August 15, 2012.

5. Stock Based Compensation

The CARBO Ceramics Inc. Omnibus Incentive Plan (the “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. The amount paid under the Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $2,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 750,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 50,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) in equal annual installments over a three-year period but subject to certain limitations, awards may specify other vesting periods. As of June 30, 2012, 569,091 shares were available for issuance under the Omnibus Incentive Plan. Although the Company’s previous stock option plan has expired, outstanding options under the plan remain outstanding in accordance with their terms.

As of June 30, 2012, all compensation cost related to stock options granted under the expired stock option plan has been recognized. There were no stock options exercised during the six months ended June 30, 2012. The weighted-average remaining contractual term of the 2,425 options outstanding at June 30, 2012 was approximately 3 months.

A summary of restricted stock activity and related information for the six months ended June 30, 2012 is presented below:

	Shares			Weighted- Average Grant-Date Fair Value
Nonvested at January 1, 2012		129,082		$	75.00
Granted		55,652		$	119.22
Vested		(58,461	)	$	66.15
Forfeited		(3,946	)	$	93.80
Nonvested at June 30, 2012		122,327		$	98.75

As of June 30, 2012, there was $7,944 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under the Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.7 years. The total fair value of shares vested during the six months ended June 30, 2012 was $3,867.

8

The Company has made phantom stock awards to key international employees pursuant to the Omnibus Incentive Plan. The units subject to an award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom shares 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 shares. As of June 30, 2012, there were 10,105 units of phantom shares granted under the Omnibus Incentive Plan, of which 3,429 have vested and 1,076 have been forfeited, with a total value of $430, a portion of which is accrued as a liability within Other Accrued Expenses.

6. Bank Borrowings

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. During the six-month period ended June 30, 2012, the Company borrowed and repaid $10,000 under the line of credit.

7. Foreign Currencies

As of June 30, 2012, the Company’s net investment that is subject to foreign currency fluctuations totaled $86,816 and the Company has recorded cumulative foreign currency translation loss of $4,626, net of deferred income tax benefit. This cumulative translation loss is included in Accumulated Other Comprehensive Loss.

8. New Accounting Pronouncements

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.

9. Legal Proceedings

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.

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”). The suit 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. 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

9

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”), which alleges substantially similar claims as the February SDNY Lawsuit and requests unspecified damages and costs. In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated, and will now proceed as one lawsuit.

On April 19, 2012, a third purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of Texas, which was also brought on behalf of shareholders who purchased shares during the Relevant Time Period. This lawsuit alleged substantially similar claims as the February SDNY Lawsuit and requested unspecified damages and costs. In June 2012, this lawsuit was dismissed without prejudice.

On March 1, 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 “March Harris County Lawsuit”). The suit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit, and requests unspecified damages and costs. The parties to this lawsuit have entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuit.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a second purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (this lawsuit collectively with the March Harris County Lawsuit, the “Harris County Lawsuits”). This lawsuit alleges substantially similar claims as the March Harris County Lawsuit as well as a breach of duty against certain defendants in connection with stock sales. This lawsuit also requests unspecified damages and costs. The parties to this 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 Harris County Lawsuits are in their preliminary stages, the Company does not believe they have merit, and plans to vigorously contest and defend against them.

The Company cannot predict the ultimate outcome or duration of these lawsuits.

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

Business

The Company generates revenue primarily through the sale of products and services to the oil and natural 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. 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, along with geotechnical monitoring.

Critical Accounting Policies

The consolidated financial statements are prepared in accordance with United States generally accepted accounting principles, which require the Company to make estimates and assumptions (see Note 1 to the consolidated financial statements included in the annual report on Form 10-K for the year ended December 31, 2011). The Company believes that some of its accounting policies involve a higher degree of judgment and complexity than others. As of December 31, 2011, critical accounting policies for the Company 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 the Company’s annual report on Form 10-K for the year ended December 31, 2011. There have been no changes in the Company’s evaluation of its critical accounting policies since December 31, 2011.

Results of Operations

Three Months Ended June 30, 2012

Revenues. Revenues of $177.6 million for the quarter ended June 30, 2012 increased 19% compared to $149.7 million in revenues for the same period in 2011. The increase is mainly attributed to a 17% increase in proppant sales volume and an increase in revenues of some of the Company’s other business units. Worldwide proppant sales volume totaled 454 million pounds for the second quarter of 2012 compared to 387 million pounds for the second quarter of 2011. North American (defined as Canada and the U.S.) sales volume increased 17% largely driven by 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 20% primarily due to increased sales volumes in Mexico and Russia. Other Proppants (resin-coated sand and ceramic proppant manufactured on an outsourced basis) represented 51 million pounds of the Company’s worldwide sales volumes in the second quarter of 2012, as compared to 23 million pounds in the second quarter of 2011. The average selling price per pound of all proppant remained relatively flat at $0.358 during the second quarter of 2012 compared to $0.356 for the same period in 2011.

Gross Profit. Gross profit for the second quarter of 2012 was $64.3 million, or 36% of revenues, compared to $62.1 million, or 42% of revenues, for the second quarter of 2011. The increase in gross profit was primarily the result of higher proppant sales volumes and a greater contribution from some of the Company’s other business units, partially offset by an increase in freight and logistics costs. Gross profit as a percentage of revenues decreased primarily as a result of higher freight and logistics costs and a change in the mix of products sold.

Selling, General and Administrative (SG&A). SG&A expenses totaled $17.1 million for the second quarter of 2012 compared to $15.8 million for the same period in 2011. As a percentage of revenues, SG&A expenses decreased to 9.6% compared to 10.6% for the second quarter of 2011.

Other Income (Expense). Other income for the second quarter of 2012 increased $0.8 million compared to the same period in 2011. This increase is mainly attributed to gains resulting from changes in exchange rates between the functional currency and the foreign currency in which the effective transactions were denominated.

Income Tax Expense. Income tax expense was $16.0 million, or 33.3% of pretax income, for the second quarter of 2012 compared to $16.2 million, or 35.2% of pretax income, for the same period last year. The lower effective tax rate is primarily due to additional tax benefits relating to mining depletion deductions.

Six Months Ended June 30, 2012

Revenues. Revenues of $340.8 million for the six months ended June 30, 2012 increased 13% compared to $300.5 million in revenues for the same period in 2011. Revenues increased primarily due to a 9% increase in proppant sales volume, a 3% increase in the average proppant selling price and an increase in revenues for some of the Company’s other business units. Worldwide proppant sales volume totaled 857 million pounds in the first six months of 2012 compared to 785 million pounds for the same period in 2011. North American (defined as Canada and the U.S.) sales volume increased 7% due primarily 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 21% primarily due to increased sales volumes in Mexico, Russia and China. Other Proppants (resin-coated sand and ceramic proppant manufactured on an outsourced basis) represented 92 million pounds of the Company’s worldwide sales volumes in the first six months of 2012, as compared to 46 million pounds for the same period in 2011. The average selling price per pound of all proppant was $0.364 during the six months ended June 30, 2012 compared to $0.353 for the same period in 2011.

Gross Profit. Gross profit for the six months ended June 30, 2012 was $127.7 million, or 37% of revenues, compared to $124.2 million, or 41% of revenues, for the same period in 2011. The increase in gross profit was primarily the result of higher proppant sales volumes, an increase in the average proppant selling price and a greater contribution from some of the Company’s other business units, partially offset by an increase in freight and logistics costs. Gross profit as a percentage of revenues decreased primarily as a result of higher freight and logistics costs and a change in the mix of products sold.

Selling, General and Administrative (SG&A) and Other Operating Expenses. SG&A expenses totaled $33.7 million for the six months ended June 30, 2012 compared to $30.1 million for the same period in 2011. As a percentage of revenues, SG&A expenses remained relatively flat at 9.9% for the six months ended June 30, 2012 compared to 10.0% for the same period in 2011. The increase in SG&A expenses primarily resulted from higher marketing, research and development, and administrative spending. Start-up costs of $0.1 million in 2012 related to the start-up of the second resin-coating line at the Company’s New Iberia, Louisiana facility. Loss on disposal or impairment of assets of $1.6 million in 2011 consists primarily of a $0.9 million impairment of goodwill related to the Company’s geotechnical monitoring business and a $0.8 million 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.

Other Income (Expense). Other expense for the six months ended June 30, 2012 decreased $0.2 million compared to the same period in 2011 due primarily to changes in exchange rates between the functional currency and the foreign currency in which the effective transactions were denominated.

Income Tax Expense. Income tax expense was $31.7 million, or 33.7% of pretax income, for the six months ended June 30, 2012 compared to $31.9 million, or 34.7% of pretax income for the same period last year. The lower effective tax rate is due primarily to additional tax benefits in 2012 relating to mining depletion deductions.

Outlook

The Company believes its operating results for the remainder of 2012 will continue to be influenced by the level of oil and natural gas drilling in North America. A severe decline in natural gas prices in the U.S. in late 2011 led businesses engaged in the exploration and production of oil and natural gas to reduce drilling activity and capital spending in natural gas basins, including shale plays, and to increase capital spending towards oily, liquids-rich basins.

The continuing shift in oilfield activity by the Company’s clients to oily, liquids-rich plays remains encouraging. However, the combination of a low natural gas price, volatility in oil and natural gas liquids markets, and the over-supply of imported Chinese ceramic proppant is causing disruptions within the industry, and the Company believes these disruptions will place pressure on proppant pricing, volumes and margins for the remainder of the year. In addition, the increased amount of activity in infrastructure-limited, liquids-rich basins introduced supply chain challenges to the industry. These challenges resulted in higher supply chain costs in the first half of 2012 for the Company. The Company expects that a portion of these costs will likely continue for the balance of the year.

12

The Company expects to support near-term demand with its current ceramic production capacity of 1.7 billion pounds per year, along with existing inventories of ceramic proppant that meets API/ISO standards manufactured on an outsourced basis. With respect to resin-coating capacity expansion, the second production line in New Iberia, Louisiana was completed during the first quarter of 2012 and increased the Company’s annual resin-coating capacity to 400 million pounds. Near the end of the second quarter of 2012, the Company began to utilize its own northern white sand in its sand processing facility in Marshfield, Wisconsin. With respect to the resin-coating expansion in Marshfield, the Company has deferred further construction at this time. The Company will consider resuming construction when warranted by market conditions. Additionally, 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 construction of the first 250 million pound line and anticipates the Millen plant could commence operation before the end of 2013.

Liquidity and Capital Resources

At June 30, 2012, the Company had cash and cash equivalents of $34.9 million compared to cash and cash equivalents of $41.3 million at December 31, 2011. For the six months ended June 30, 2012, the Company generated $61.8 million of cash from operating activities and $1.3 million from excess tax benefits relating to stock based compensation. Uses of cash included $50.3 million of capital spending, $11.1 million of cash dividends, $7.7 million for the repurchases of the Company’s Common Stock and $0.4 million for the effect of exchange rate changes on cash. In addition, during the first six months of 2012, the Company borrowed and fully repaid a total of $10.0 million on its credit facility.

Subject to the Company’s 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 July 17, 2012, the Board of Directors declared a cash dividend of $0.27 per common share payable to shareholders of record on August 1, 2012. This dividend is payable on August 15, 2012. The Company estimates its total capital expenditures for the remainder of 2012 will be between $45.0 million and $55.0 million. Capital expenditures for the remainder of 2012 are expected to include costs associated with expansion of the Company’s distribution infrastructure and the construction of the new manufacturing facility in the Millen, Georgia area.

The Company maintains a $25.0 million unsecured line of credit with Wells Fargo Bank, N.A. As of June 30, 2012, there was no outstanding debt under the credit agreement. The Company anticipates that cash on hand, cash provided by operating activities and funds available under 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. 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.

Off-Balance Sheet Arrangements

The Company had no off-balance sheet arrangements as of June 30, 2012.

Forward-Looking Information

The statements in this 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 the forward-looking statements. Among these factors are:

• changes in overall economic conditions,

• changes in the cost of raw materials and natural gas used in manufacturing our products,

• changes in demand and prices charged for our products,

• changes in the demand for, or price of, oil and natural gas,

• risks of increased competition,

• technological, manufacturing and product development risks,

• loss of key customers,

• changes in foreign and domestic government regulations, including environmental restrictions on operations and regulation of hydraulic fracturing,

• changes in foreign and domestic political and legislative risks,

13

• the risks of war and international and domestic terrorism,

• risks associated with foreign operations and foreign currency exchange rates and controls, and

• weather-related risks and other risks and uncertainties.

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”). See in particular our annual report on Form 10-K for the fiscal year ended December 31, 2011 under the caption “Risk Factors” and similar disclosures in subsequently filed reports with the SEC. We assume no obligation to update forward-looking statements, except as required by law.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company’s major market risk exposure is to foreign currency fluctuations that could impact its investments in China and Russia. As of June 30, 2012, the Company’s net investment that is subject to foreign currency fluctuations totaled $86.8 million and the Company has recorded a cumulative foreign currency translation loss of $4.6 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 June 30, 2012.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

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 June 30, 2012, 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 the Company’s 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 the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it files or submits 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 required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2012, that materially affected, or are reasonably likely to materially affect, those controls.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On February 9, 2012, the Company, 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”). The suit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made

14

during the class period and requests unspecified damages and costs. 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 investors 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”), which alleges substantially similar claims as the February SDNY Lawsuit and requests unspecified damages and costs. In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated, and will now proceed as one lawsuit.

On April 19, 2012, a third purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of Texas, which was also brought on behalf of shareholders who purchased shares during the Relevant Time Period. This lawsuit alleged substantially similar claims as the February SDNY Lawsuit and requested unspecified damages and costs. In June 2012, this lawsuit was dismissed without prejudice.

On March 1, 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 “March Harris County Lawsuit”). The suit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit, and requests unspecified damages and costs. The parties to this lawsuit have entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuit.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a second purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (this lawsuit collectively with the March Harris County Lawsuit, the “Harris County Lawsuits”). This lawsuit alleges substantially similar claims as the March Harris County Lawsuit as well as a breach of duty against certain defendants in connection with stock sales. This lawsuit also requests unspecified damages and costs. The parties to this lawsuit have 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 Harris County Lawsuits 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.

NINTH: The corporation reserves the right to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate of Incorporation in the manner now or hereafter prescribed by law, and all rights and powers conferred herein on stockholders, directors and officers are subject to this reserved power.

5. The Restated Certificate of Incorporation as hereinabove set forth was duly adopted pursuant to Section 245 of the Delaware General Corporation Law at a meeting of the Board of Directors of the corporation on July 17, 2012.

IN WITNESS WHEREOF, said CARBO CERAMICS INC. has caused this Certificate to be executed by its duly authorized officer, on this 18th day of July, 2012.

Stock Based Compensation

5. Stock Based Compensation

The CARBO Ceramics Inc. Omnibus Incentive Plan (the “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. The amount paid under the Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $2,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 750,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 50,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) in equal annual installments over a three-year period but subject to certain limitations, awards may specify other vesting periods. As of June 30, 2012, 569,091 shares were available for issuance under the Omnibus Incentive Plan. Although the Company’s previous stock option plan has expired, outstanding options under the plan remain outstanding in accordance with their terms.

As of June 30, 2012, all compensation cost related to stock options granted under the expired stock option plan has been recognized. There were no stock options exercised during the six months ended June 30, 2012. The weighted-average remaining contractual term of the 2,425 options outstanding at June 30, 2012 was approximately 3 months.

A summary of restricted stock activity and related information for the six months ended June 30, 2012 is presented below:

	Shares			Weighted- Average Grant-Date Fair Value
Nonvested at January 1, 2012		129,082		$	75.00
Granted		55,652		$	119.22
Vested		(58,461	)	$	66.15
Forfeited		(3,946	)	$	93.80
Nonvested at June 30, 2012		122,327		$	98.75

As of June 30, 2012, there was $7,944 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under the Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.7 years. The total fair value of shares vested during the six months ended June 30, 2012 was $3,867.

The Company has made phantom stock awards to key international employees pursuant to the Omnibus Incentive Plan. The units subject to an award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom shares 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 shares. As of June 30, 2012, there were 10,105 units of phantom shares granted under the Omnibus Incentive Plan, of which 3,429 have vested and 1,076 have been forfeited, with a total value of $430, a portion of which is accrued as a liability within Other Accrued Expenses.

Legal Proceedings

9. Legal Proceedings

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.

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”). The suit 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. 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”), which alleges substantially similar claims as the February SDNY Lawsuit and requests unspecified damages and costs. In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated, and will now proceed as one lawsuit.

On April 19, 2012, a third purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of Texas, which was also brought on behalf of shareholders who purchased shares during the Relevant Time Period. This lawsuit alleged substantially similar claims as the February SDNY Lawsuit and requested unspecified damages and costs. In June 2012, this lawsuit was dismissed without prejudice.

On March 1, 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 “March Harris County Lawsuit”). The suit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit, and requests unspecified damages and costs. The parties to this lawsuit have entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuit.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a second purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (this lawsuit collectively with the March Harris County Lawsuit, the “Harris County Lawsuits”). This lawsuit alleges substantially similar claims as the March Harris County Lawsuit as well as a breach of duty against certain defendants in connection with stock sales. This lawsuit also requests unspecified damages and costs. The parties to this 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 Harris County Lawsuits are in their preliminary stages, the Company does not believe they have merit, and plans to vigorously contest and defend against them.

The Company cannot predict the ultimate outcome or duration of these lawsuits.

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.
