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. As of March 31, 2014, 451,226 shares were available for issuance under the Omnibus Incentive Plan.

The Company has made restricted stock awards pursuant to the Omnibus Incentive Plan. A summary of restricted stock activity and related information for the three months ended March 31, 2014 is presented below:

	Shares			Weighted- Average Grant-Date Fair Value
Nonvested at January 1, 2014		136,195		$	90.50
Granted		73,785		$	112.19
Vested		(53,152	)	$	97.08
Forfeited		(279	)	$	112.96
Nonvested at March 31, 2014		156,549		$	98.44

As of March 31, 2014, there was $12,234 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 2.3 years. The total fair value of shares vested during the three months ended March 31, 2014 was $5,160.

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 March 31, 2014, there were 18,180 units of phantom shares granted under the Omnibus Incentive Plan, of which 9,397 have vested and 1,570 have been forfeited, with a total value of $995, 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. The credit agreement provides the Company with a revolving credit facility of $50,000 and expires on July 25, 2018. 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 an annual rate between 0.375% and 0.50% of the unused line of credit.

7. Foreign Currencies

As of March 31, 2014, the Company’s net investment that is subject to foreign currency fluctuations totaled $82,461 and the Company has recorded a cumulative foreign currency translation loss of $6,339, net of deferred income tax benefit. 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 three months ended March 31, 2014.

8. 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”). On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”, and collectively with the February SDNY Lawsuit, the “Federal Securities Lawsuit”). In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated. The Federal Securities Lawsuit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. In September 2012, the Company and Messrs. Kolstad and Bautista filed a motion to dismiss this lawsuit. The motion to dismiss was granted, and the Federal Securities Lawsuit was dismissed without prejudice in June 2013. In September 2013, the plaintiffs filed a motion requesting leave to file a second amended complaint and sustain the lawsuit. In January 2014, the Court denied plaintiffs’ motion, and entered a judgment in favor of the Company and Messrs. Kolstad and Bautista. The plaintiffs did not timely appeal this judgment, and it has become final.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “Harris County Lawsuit”). This lawsuit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the Federal Securities Lawsuit, as well as a breach of duty by certain defendants in connection with stock sales. The lawsuit requests unspecified damages and costs, and had been further stayed, pending final resolution of the Federal Securities Lawsuit. Given the final judgment in the Federal Securities Lawsuit, the plaintiff in the Harris County Lawsuit agreed to dismiss this case. The lawsuit was dismissed without prejudice in March 2014.

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

Business

The Company generates revenue primarily through the sale of production enhancement products and services to the oil and natural gas industry. The Company’s 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 ceramic, and resin-coated sand. The Company also provides the industry’s most widely used hydraulic fracture simulation software, FracPro^®, as well as hydraulic fracture design and consulting services. In addition, the Company provides a broad range of technologies for spill prevention, containment and countermeasures.

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, 2013). The Company believes that some of its accounting policies involve a higher degree of judgment and complexity than others. As of December 31, 2013, 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, 2013. There have been no changes in the Company’s evaluation of its critical accounting policies since December 31, 2013.

Results of Operations

Three Months Ended March 31, 2014

Revenues. Revenues of $148.6 million for the first quarter of 2014 increased 1% compared to $147.7 million for the same period in 2013. The increase is mainly attributed to a 30% increase in the total proppant sales volume that was driven by higher sales volumes of lower priced sand-based proppants, which was partially offset by a decrease in Falcon revenues. The average selling price per pound of all proppant was $0.238 during the first quarter of 2014 compared to $0.302 for the same period in 2013.

Worldwide proppant sales volumes in the first quarter of 2014 compared to the same period in 2013 are as follows.

Proppant Sales Volumes (in million lbs)	Three Months Ended March 31,
	2014		2013
Ceramic		373		398
Resin Coated Sand		48		25
Northern White Sand		157		22
Total		578		445

North American (defined as Canada and the U.S.) proppant sales volume increased 39%, driven largely by increases in sand-based sales volumes despite cold weather conditions and related distribution issues that continued to impact drilling activities in the northern regions. International (excluding Canada) sales volume decreased 18% primarily due to decreased sales volumes in China and Russia, partially offset by increased sales volumes in Mexico.

Gross Profit. Gross profit for the first quarter of 2014 was $44.4 million, or 30% of revenues, compared to $42.4 million, or 29% of revenues, for the first quarter of 2013.

Selling, General and Administrative (SG&A) and Other Operating Expenses. SG&A and other operating expenses totaled $17.0 million for the first quarter of 2014, which was flat compared to the first quarter of 2013. As a percentage of revenues, SG&A and other operating expenses decreased to 11.4% in 2014 compared to 11.5% for the first quarter of 2013.

10

Income Tax Expense. Income tax expense was $9.1 million, or 33.0% of pretax income, for the first quarter of 2014 compared to $7.9 million, or 31.1% of pretax income, for the same period last year. The $1.2 million increase is primarily due to higher pre-tax income combined with $0.4 million in R&D tax credits realized as a result of legislation enacted in the first quarter of 2013 that did not impact the first quarter of 2014.

Outlook

The Company expects activity will continue to be variable and driven by weather conditions in certain regions and by exploration and production companies focusing on a balance between reducing well costs and investment returns through optimization of well completions. However, the Company anticipates demand for its production enhancement products and services to remain intact. Furthermore, as previously mentioned, the Company remains positive on industry activity and ceramic sales volumes for the balance of 2014 and believes the majority of the completion activity that was delayed in the first quarter of 2014 has shifted to the second and third quarters of 2014. The Company believes its ceramic volumes could increase for the second quarter of 2014 when compared to the first quarter of 2014, subject to the typical second quarter spring break up and lingering weather effects. The Company also believes proppant pricing will remain relatively flat during the second quarter of 2014.

Construction on the first and second production lines in Millen, Georgia remain on schedule with completions expected by the end of the second quarter of 2014 and 2015, respectively. Once both lines are completed, the Company’s ceramic proppant manufacturing capacity will increase by 500 million pounds to a total of 2.25 billion pounds per year. Additionally, the retrofit of an existing manufacturing line continues with the Company’s KRYPTOSPHERE^TM proppant technology. Initial sales of KRYPTOSPHERE LD from this retrofit are presently expected by the end of the second quarter of 2015.

The Company is building inventories of KRYPTOSPHERE HD, the new ultra-conductive, ultra-high strength proppant for deep well applications. The Gulf of Mexico is the primary target market; but some Gulf of Mexico deep water completion activity has been delayed at least until the second half of 2014.

Liquidity and Capital Resources

At March 31, 2014, the Company had cash and cash equivalents of $86.1 million compared to cash and cash equivalents of $94.3 million at December 31, 2013. During the first quarter of 2014, the Company generated $44.1 million of cash from operating activities. Uses of cash included $38.9 million for capital expenditures, $6.9 million for the payment of cash dividends and $5.8 million for repurchases of the Company’s common stock.

Subject to its financial condition, the amount of funds generated from operations and the level of capital expenditures, the Company’s current intention is to continue to pay quarterly dividends to holders of its common stock. On March 18, 2014, the Company’s Board of Directors approved the payment of a quarterly cash dividend of $0.30 per share to shareholders of the Company’s common stock on May 1, 2014. The dividend is payable on May 15, 2014. The Company estimates its total capital expenditures for the remainder of 2014 will be between $140.0 million and $160.0 million, which include costs associated with the construction of the new manufacturing facility in Millen, Georgia, retrofitting an existing plant with the new proppant manufacturing technology, expansion of the Company’s distribution infrastructure, as well as various other projects and additions.

The Company maintains a $50 million unsecured line of credit with a bank that matures in July 2018. As of March 31, 2014, there was no outstanding debt under the credit agreement. The Company anticipates that cash on hand, cash provided by operating activities and funds provided by its line of credit will be sufficient to meet planned operating expenses, tax obligations, capital expenditures and other cash needs for the next 12 months. The Company also believes that it could acquire additional debt financing, if needed. Based on these assumptions, the Company believes that its fixed costs could be met even with a moderate decrease in demand for the Company’s products.

Off-Balance Sheet Arrangements

The Company had no off-balance sheet arrangements as of March 31, 2014.

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 March 31, 2014, the Company’s net investment that is subject to foreign currency fluctuations totaled $82.5 million and the Company has recorded cumulative foreign currency translation loss of $6.3 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 March 31, 2014.

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.

12

As of March 31, 2014, 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 March 31, 2014 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 and two of its officers, Gary A. Kolstad and Ernesto Bautista III, were named as defendants in a purported class-action lawsuit filed in the United States District Court for the Southern District of New York (the “February SDNY Lawsuit”), brought on behalf of shareholders who purchased the Company’s Common Stock between October 27, 2011 and January 26, 2012 (the “Relevant Time Period”). On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”, and collectively with the February SDNY Lawsuit, the “Federal Securities Lawsuit”). In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated. The Federal Securities Lawsuit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. In September 2012, the Company and Messrs. Kolstad and Bautista filed a motion to dismiss this lawsuit. The motion to dismiss was granted, and the Federal Securities Lawsuit was dismissed without prejudice in June 2013. In September 2013, the plaintiffs filed a motion requesting leave to file a second amended complaint and sustain the lawsuit. In January 2014, the Court denied plaintiffs’ motion, and entered a judgment in favor of the Company and Messrs. Kolstad and Bautista. The plaintiffs did not timely appeal this judgment, and it has become final.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “Harris County Lawsuit”). This lawsuit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the Federal Securities Lawsuit, as well as a breach of duty by certain defendants in connection with stock sales. The lawsuit requests unspecified damages and costs, and had been further stayed, pending final resolution of the Federal Securities Lawsuit. Given the final judgment in the Federal Securities Lawsuit, the plaintiff in the Harris County Lawsuit agreed to dismiss this case. The lawsuit was dismissed without prejudice in March 2014.

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.

Exhibit 10.2

Description of Modification to

Annual Non-Employee Director Stock Grants

In March 2014, the Compensation Committee of the Board of Directors of CARBO Ceramics Inc. (the “Company”) approved a change in the calculation of the number of shares of the Company’s common stock to be made each year on the first business day after the date of the Company’s Annual Meeting of Stockholders to each non-employee Director of the Company serving as such on such date (each, an “Annual Director Stock Grant”). Beginning with the 2014 Annual Director Stock Grant, the number of shares granted will be determined by dividing One Hundred Thousand Dollars ($100,000) by the closing price for the Company’s Common Stock on the grant date. All other terms of the Annual Director Stock Grants, as established in May 2010, remain unchanged.

8. 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”). On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”, and collectively with the February SDNY Lawsuit, the “Federal Securities Lawsuit”). In June 2012, the February SNDY Lawsuit and the April SDNY Lawsuit were consolidated. The Federal Securities Lawsuit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. In September 2012, the Company and Messrs. Kolstad and Bautista filed a motion to dismiss this lawsuit. The motion to dismiss was granted, and the Federal Securities Lawsuit was dismissed without prejudice in June 2013. In September 2013, the plaintiffs filed a motion requesting leave to file a second amended complaint and sustain the lawsuit. In January 2014, the Court denied plaintiffs’ motion, and entered a judgment in favor of the Company and Messrs. Kolstad and Bautista. The plaintiffs did not timely appeal this judgment, and it has become final.

On June 13, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “Harris County Lawsuit”). This lawsuit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the Federal Securities Lawsuit, as well as a breach of duty by certain defendants in connection with stock sales. The lawsuit requests unspecified damages and costs, and had been further stayed, pending final resolution of the Federal Securities Lawsuit. Given the final judgment in the Federal Securities Lawsuit, the plaintiff in the Harris County Lawsuit agreed to dismiss this case. The lawsuit was dismissed without prejudice in March 2014.
