CARBO CERAMICS INC. ANNOUNCES SECOND QUARTER 2012 EARNINGS

Conference Call Scheduled for Today, 10:00 a.m. Central Time

HOUSTON, TX (July 26, 2012) — CARBO Ceramics Inc. (NYSE: CRR) today reported net income of $31.9 million, or $1.38 per diluted share, on revenues of $177.6 million for the quarter ended June 30, 2012.

President and CEO Gary Kolstad commented, “Sales volumes set a new quarterly record despite difficult market conditions, including an over-supply of varying quality Chinese ceramic proppant in North America. We achieved this sales volume record through our continued focus to further expand the use of CARBO’s high quality, high conductivity ceramic proppant in the liquids-rich basins, namely the Bakken and Eagle Ford. Although sales volumes were healthy in these basins, infrastructure to support industry activity remained limited. From a distribution standpoint, we continued to face logistical challenges and higher associated costs during the quarter.

“Our sand processing plant in Marshfield, Wisconsin became operational late in the second quarter of 2012. Shipments of our high quality, CARBO Northern White sand have started to arrive at our resin-coating facility in New Iberia.

“E&P clients’ continued focus on environmental risk reduction led to record quarterly sales for Falcon Technologies^®. Falcon’s technologically advanced spill prevention and containment systems are widely respected in the industry and provide superior protection for operators of oil and gas well sites.

“The Board of Directors recently approved a 13 percent increase in the dividend. This marks the twelfth consecutive year we have increased the dividend, and the Board’s decision demonstrates continued confidence in our long-term cash flow outlook,” Mr. Kolstad said.

Second Quarter Results

Revenues for the second quarter of 2012 increased 19 percent, or $27.9 million, when compared to the second quarter of 2011. North American (defined as Canada and the U.S.) proppant sales volume increased 17 percent while International proppant sales volume increased 20 percent, compared to the same period last year.

Operating profit for the second quarter of 2012 increased 2 percent, or $0.9 million, compared to the second quarter of 2011. The increase in operating 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 changes in product mix and increases in freight, logistics, and SG&A expenses.

Net income for the second quarter of 2012 increased 7 percent, or $2.0 million compared to the second quarter of 2011.

Technology and Business Highlights

Outlook

CEO Gary Kolstad commented on the outlook for CARBO stating, “As we noted previously, 2012 will have its share of challenges due to the shift in activity away from natural gas basins towards liquids-rich basins in North America. The combination of a low natural gas price, volatility in oil and NGL markets, and the over-supply of varying quality Chinese ceramic proppant is causing disruptions within the industry, and we expect these disruptions to place pressure on proppant pricing, volumes and margins for the remainder of the year.

“The construction of our Marshfield resin-coating plant has been deferred at this time. We continue to monitor market conditions and we will modify the project timeline accordingly. Work on the Millen, Georgia ceramic manufacturing plant project continues and we estimate the plant could commence production before the end of 2013.

“Resin-coating production in New Iberia will likely be limited through the third quarter of 2012 as we build a sufficient inventory of CARBO Northern White sand.

“We expect Falcon to build upon its success this year and achieve revenue growth of 15 percent to 20 percent for 2012 as indicated previously.

“Although the operating environment is difficult, we will continue to focus on what CARBO does best, making oil and gas wells produce better and achieve higher ultimate recovery rates. CARBO’s ceramic proppant provides its clients two important technical advantages over the varying quality Chinese Intermediate Density Ceramic (IDC) proppant. First, our clients achieve superior conductivity due to the consistency of the high quality proppant we manufacture in the United States. Second, our clients benefit from utilizing CARBO’s lightweight ceramic proppant which provides approximately 20 percent more proppant volume for every pound purchased. Said differently, users of IDC proppant would have to purchase roughly 20 percent more IDC to achieve the same fracture volume as compared to a well that uses CARBO’s lightweight ceramic proppant.

“We will continue to demonstrate the benefits of Economic Conductivity^® and the value of our high quality, high conductivity ceramic proppant. We believe focusing on technology and value creation for our E&P clients will assist us in achieving long-term success in our business,” Mr. Kolstad concluded.
