CARBO ANNOUNCES SECOND QUARTER 2013 EARNINGS

Conference Call Scheduled for Today, 10:30 a.m. Central Time

• Quarterly revenues of $153.7 million compared to $177.6 million during the same quarter in the prior year

• Net income of $16.3 million, or $0.71 per diluted share for the quarter

• Quarterly dividend was raised 11% and marks the 13^th consecutive year of a dividend increase

HOUSTON, TX (July 25, 2013) – CARBO Ceramics Inc. (NYSE: CRR) today reported net income of $16.3 million, or $0.71 per share, on revenues of $153.7 million for the quarter ended June 30, 2013.

President and CEO Gary Kolstad commented, “We are pleased with the progress we made in our production enhancement businesses during the quarter. In the latter part of the quarter, we experienced increased demand for ceramic proppants and improved margins.

“Market conditions remained challenging during the second quarter of 2013. E&P operators continue to focus on lowering completion costs, at times sacrificing estimated ultimate recovery (EUR). Additionally, there continues to be excess capacity of low quality Chinese ceramic proppant in the market. However, we believe inventories of this low quality Chinese ceramic proppant appear to be shrinking. Through our aggressive technical marketing campaign, we continue to educate the industry on the negative aspects of lower quality Chinese ceramic proppant. Through imagery, the campaign highlights the irregular size and shape, the rough surfaces and the internal defects of the pellets. Long-term conductivity data confirms the damaging effects these characteristics have on well production. We believe our technical marketing campaign is being well received by our clients.

“Our ceramic proppant sales volumes were down five percent sequentially, largely a result of seasonality, including the Canadian spring breakup. Ceramic proppant pricing was up one percent sequentially due to product mix.

“Our production enhancement technology product offerings continue to expand. During the quarter, our latest solution, SCALEGUARD^TM, was pumped in wells for a large operator in the Bakken. In addition, we made progress in bringing our new proppant technology, initially aimed at ultra-deep wells, closer to commercialization.

“We also made progress in our sales of resin-coated sand products (RCS), as volumes increased compared to the first quarter of 2013. Margins in the RCS product line remain challenged, as the RCS market is oversupplied, and we have been operating at low plant utilization levels.

“With respect to proppant distribution costs, we continue to work on driving out inefficiencies in the system. This includes reducing our costs through rationalizing our rail fleet, increasing proppant storage and reducing transportation costs.

“Our Fracpro^® fracture design software continues to expand its client base globally, while StrataGen^® consulting remains focused on client expansion in the main U.S. shale basins. These businesses are key elements of our production enhancement offerings.

“Our environmental spill prevention and containment business, Falcon Technologies^®, experienced revenue growth both year over year and sequentially, primarily due to an increase in its client base and geographic market expansion.

“The Board of Directors recently approved an 11 percent increase in CARBO’s quarterly dividend. This marks the thirteenth consecutive year we have increased the dividend, and is a testament to the Board’s continued confidence in our long-term cash flow outlook,” Mr. Kolstad said.

Second Quarter Results

Revenues for the second quarter of 2013 decreased 13 percent, or $23.9 million, compared to the second quarter of 2012. The decrease is mainly attributed to two factors. First, ceramic proppant sales volumes were lower as a result of lower drilling activity. Second, CARBO experienced a decrease in the average proppant selling price for all proppants. North American (defined as Canada and the U.S.) proppant sales volumes increased 3 percent while international proppant sales volumes decreased 13 percent, compared to the same period last year.

Operating profit for the second quarter of 2013 decreased 49 percent, or $23.4 million, compared to the second quarter of 2012. The decrease in operating profit was primarily the result of a decrease in average selling price, higher ceramic proppant unit costs resulting from lower plant utilization and a change in the product sales mix resulting from volume gains of the Company’s sand-based products. In addition, spending to bring the new proppant technology to a commercial state continued, which reduced second quarter earnings per share by approximately $0.08.

Net income for the second quarter of 2013 decreased 49 percent, or $15.6 million, compared to the second quarter of 2012.

CARBO repurchased 45,000 shares of its common stock at an average price of $70.00 per share during the second quarter of 2013 pursuant to its previously announced stock repurchase program. Since September 2008, 1.95 million shares have been repurchased at an average price of $43.09 per share.

Technology and Business Highlights

• A large Bakken operator successfully employed SCALEGUARD along with CARBOECONOPROP^® in two wells. SCALEGUARD, a ceramic proppant infused with scale inhibiting chemicals, is placed throughout the fracture as part of the standard fracturing process. It provides efficient, long-term protection against scale formation in a single treatment, while maintaining maximum fracture conductivity.

• Jetta Operating Company is using CARBOBONDLITE^®, a curable resin-coated premium lightweight ceramic proppant, in its third Bone Springs horizontal completion near Pecos, Texas. Jetta is extremely satisfied with the product’s performance and has observed that the wells using CARBO’s curable resin-coated ceramic proppant flow unassisted for 18-24 months compared to similar offset wells that require artificial lift after just three to six months.

• Blackbrush Oil & Gas employed both StrataGen consulting services and CARBO ceramic proppant in their Pearsall Shale wells in Frio County, Texas. StrataGen optimized the fracture designs, conducted data analyses and provided onsite fracture execution quality control. CARBO’s high-quality lightweight ceramic proppants – CARBOHYDROPROP^® and CARBOECONOPROP – were used to stimulate the wells. Production results have been exceptional.

• Trican Well Services purchased Fracpro fracture design software for a corporate-wide operations deployment in Canada, Russia and the United States. Trican will be providing its fracture design teams and field operations with the latest Fracpro software for use in fracture design, real time and post-job analysis. The licensed software will be in both English and Russian languages.

• Falcon’s business in the Rockies continues to expand its client base. Falcon is now servicing geographical areas beyond its initial base in Colorado, providing services in Wyoming and North Dakota.

Outlook

CEO Gary Kolstad commented on the outlook for CARBO stating, “While the first half of 2013 was difficult, we believe the second half has the potential to be better. Coming out of the second quarter of 2013, we witnessed improving trends in volumes and margins. Pricing pressures are still evident in today’s market, but increased ceramic volumes coupled with successful execution on cost reduction initiatives could lead to improved sequential margins.

“Increasing proppant sales volumes is a primary objective as we enter the second half of 2013. Field trials have been ongoing for several quarters to demonstrate the benefits that a high quality, high conductivity ceramic proppant can provide in clients’ production and EUR. The production data we have gathered from these liquids-rich shale field trials has been positive and indicates the need for higher quality, higher conductivity proppant in wells that experience multi-phase and non-Darcy flow. These positive results, along with what appear to be lower ceramic proppant import levels, should work in our favor.

“We are addressing distribution costs head-on with a number of ongoing initiatives. A critical initiative is rationalizing our rail fleet as we reduce our reliance on the fleet as a form of storage. Other initiatives include reducing transportation costs. We anticipate completing a majority of these initiatives in the second half of 2013 with the resulting benefits seen in 2014.

“With regard to our RCS products, it is unlikely that we will see large, near-term price increases on these products, given the current low natural gas activity and industry oversupply. We are focused on improving margins through efficient plant utilization and lowering certain manufacturing costs.

“We remain excited about our new proppant technology and growing our production enhancement solutions business. The commercial launch of this new proppant is scheduled for the annual Society of Petroleum Engineer’s meeting in September of this year. This product represents a new class of proppant with greater conductivity that will increase the production and ultimate recovery in ultra-deep reservoir completions. Initial efforts will focus on the deep wells in the Gulf of Mexico, where depths can reach greater than 30,000 feet. The next opportunity for this technology will be a broader application to our existing proppant product lines.

“Construction on the first line at our Millen, Georgia location is progressing, with planned completion anticipated near the end of the second quarter of 2014. Upon completion, our total annual ceramic manufacturing capacity will increase from 1.75 billion pounds to 2.0 billion pounds.

“Falcon Technologies continues to leverage its Engineered to Protect^® product suite, providing environmental spill prevention and containment for clients in the oil and gas industry. For 2013, we anticipate Falcon’s revenues to grow approximately 15 percent compared to 2012.

“At CARBO, we integrate technologies and intellectual capital to design, build, and optimize the frac. We believe our foundational focus on production enhancement technologies continues to build an enduring company,” Mr. Kolstad said.
