Irving, Texas (February 1, 2007) — CARBO Ceramics Inc. (NYSE: CRR) today announced record quarterly net income of $15.0 million, or $0.61 per diluted share, on record revenues of $87.0 million for the quarter ended December 31, 2006. Revenues for the quarter increased 37 percent while net income increased 44 percent compared to the fourth quarter of 2005.

For the year ended December 31, 2006, the company reported record net income of $54.3 million, or $2.22 per diluted share, on record annual revenues of $312.1 million. Revenues and net income for the full year 2006 increased 24 percent and 16 percent, respectively, compared to the full year 2005. Full year 2006 results represent the fourth consecutive year in which the company established a new record for revenues and net income.

President and CEO Gary Kolstad commented on the quarter and full year results stating, “We are very pleased with the new revenue and net income records established for both the fourth quarter and full year 2006. This outstanding performance was the direct result of our continued investment in new proppant manufacturing capacity and in the technologies that extend the application of our fracture mapping and reservoir monitoring services offered through Pinnacle Technologies.”

Fourth quarter results

The increase in revenues compared to last year’s fourth quarter was attributable to a 24 percent increase in the volume of proppant sold, a 9 percent increase in the average selling price of the company’s proppant and a 45 percent increase in revenue from Pinnacle. Revenues for the fourth quarter of 2006 included $10.9 million from Pinnacle compared to $7.5 million for the fourth quarter of 2005. The increase in revenue in the company’s proppant business segment was due to higher sales volume both in North America and overseas markets. Pinnacle Technologies’ growth was driven by strong demand across all North American regions for fracture mapping and reservoir monitoring services and increased international software and consulting revenues.

Worldwide proppant sales totaled 236 million pounds for the quarter, an increase of 24 percent from the fourth quarter of 2005. North American proppant sales volume rose 22 percent compared to the same period last year, driven by U.S. sales increases in excess of the 16 percent increase in the natural gas rig count versus the prior year. In Canada, sales improved slightly despite a decrease in the rig count compared to last year’s fourth quarter. Sales in Mexico rebounded in the fourth quarter of 2006 after lagging 2005 results for most of the year due to decreased activity in the region. Overseas sales volume increased 39 percent compared to last year’s fourth quarter as sales in Russia reached their highest level since the third quarter of 2005.

Operating profit for the fourth quarter of 2006 increased $6.5 million, or 41 percent, compared to the previous year’s fourth quarter. The increase in operating profit compared to the fourth quarter of 2005 was due primarily to the increase in revenue in both the proppant and the fracture and reservoir diagnostic business segments. Operating profit margins in the proppant segment were down slightly due to higher costs for high-strength raw materials and distribution costs for all proppants. However, operating profit margins in the fracture and reservoir diagnostics business improved significantly as fixed costs in this service business were spread over a significantly higher revenue base. Selling, general and administrative expenses for the fourth quarter of 2006 increased $3.1 million compared to the same period last year due to increases in research and development activity, marketing activity in international markets, and administrative expenses necessary to support higher sales activity in an expanding global market. Fourth quarter 2006 results also benefited as compared to the same quarter a year earlier due to a decrease in start-up costs, which totaled $0.6 million in the fourth quarter of 2005 due to the start-up of the company’s Toomsboro, Georgia manufacturing facility.

Full year results

For the year ended December 31, 2006, revenues increased 24 percent compared to 2005. This improvement was the result of a 13 percent increase in proppant sales volume, a 9 percent increase in the average selling price of proppant, and a 27 percent increase in revenues from Pinnacle. The volume of ceramic proppant sold in North America increased 18 percent from 2005 due to proppant sales that increased in greater proportion than North American drilling activity. The North American increase in proppant sales was partially offset by a 10 percent decrease in overseas shipments due to decreased sales volume in Russia. Sales volume in Russia declined versus the prior year in each of the first three quarters of 2006 before recovering during the fourth quarter. Excluding results in Russia, sales volume in overseas markets increased 16 percent over the previous year. The higher average selling price for the company’s ceramic proppant in 2006 compared to the prior year was due to increases in list prices that went into effect in June 2005 and November 2005. These increases impacted only a portion of 2005 results while benefiting 2006 results for a full year. Revenues for the year ended December 31, 2006 included $34.1 million from Pinnacle compared to $26.9 million for 2005. The increase in Pinnacle’s revenue was due primarily to the increase in fracture mapping activity in the North American market and growth in the emerging market for reservoir diagnostics.

For the year ended December 31, 2006, operating profit increased 15 percent compared to 2005 due to greater revenue from both the proppant and the fracture and reservoir diagnostic business segments. Operating profit margins declined versus the previous year primarily due to higher manufacturing costs in the proppant segment. The primary factors contributing to manufacturing cost increases were increases in costs for natural gas, high-strength raw materials and distribution of finished goods. Selling, general and administrative expenses also increased both in absolute terms and as a percentage of revenue due to increases in research and development activity, marketing activity in international markets, and administrative expenses necessary to support higher sales activity in an expanding global market.

Full year net income for 2006 also exceeded the previous year’s results partially due to lower start-up costs than experienced during the 2005 start-up of the company’s Toomsboro facility and an increase in non-cash other income attributable to net unrealized foreign currency gains related to the company’s capital investments in Russia and China brought about by the appreciation of foreign currencies relative to the U.S. dollar.

Technology highlights

Technology highlights for the fourth quarter included:

• A long-term microseismic monitoring array was deployed for use in monitoring the distribution of steam in a steam assisted gravity drainage (SAGD) project in Canada.

• Surface tiltmeters were utilized in a non-oilfield, geotechnical application monitoring earth movement at a Canadian mining project.

• CARBOEconoprop^® lightweight ceramic proppant was successfully utilized to increase production rates while replacing sand and resin-coated sand in slickwater fracture treatments in East Texas.

Future outlook

CEO Gary Kolstad provided input on the future outlook for the company stating, “The oil and gas industry will continue to experience normal business cycles, and we caution that high natural gas inventories in the U.S. may impact drilling activity in North America in the first half of 2007. However, we believe that any downturn in North American drilling activity will be relatively short-lived, and therefore our plans for the future are unchanged. We are the technology leaders in supplying high-conductivity proppant and in fracture mapping technology, and we will continue to invest in these businesses to expand our technical capabilities and production capacity. We are actively expanding our marketing capabilities globally, and are working to integrate our product and service offerings to address the specific needs of both oilfield service companies and the companies that explore for and produce oil and gas around the world. Our twelve proppant production lines operating at five locations in the U.S. and China allow us a great deal of flexibility to adjust output to match demand.”

In 2007, the company expects to complete the construction of its manufacturing facility in Kopyesk, Russia and the expansion of its facility in Toomsboro, Georgia. As a result of these activities, additional capital spending for Pinnacle tools, normal maintenance capital expenditures and expansion of distribution facilities, total capital spending for 2007 should range from $70-$75 million. By the end of 2007, the company expects to have expanded its proppant manufacturing capacity by 80% in a two-year period. The increased investment will result in an increase in depreciation and amortization expense to approximately $25 million in 2007. The company also expects that as it continues to expand globally it will see selling, general and administrative expenses as a percentage of revenue similar to that of the fourth quarter of 2006. The company further indicated that expenses associated with the start-up of its facility in Russia should be approximately $0.5 million in the first half of the year, provided all necessary permits are received in a timely fashion.
