CARBO Ceramics Inc. Announces Record Quarterly Earnings; Conference Call Scheduled for Today, 8:00 a.m. Central Time

    IRVING, Texas, July 13 -- CARBO Ceramics Inc., a
manufacturer of ceramic proppants for use in the hydraulic fracturing of
natural gas and oil wells, today announced net income of $7.6 million or
$0.51 per share (on a diluted basis), on revenues of $35.3 million, for the
quarter ended June 30, 2001.  Both revenue and net income established new
quarterly records for the company.  For the six months ended June 30, 2001,
the company reported net income of $13.8 million or $0.92 per diluted share,
on revenues of $69.5 million.  Net income for the quarter doubled from the
second quarter of 2000 while net income for the six months ended June 30, 2001
increased 120 percent from the same period a year earlier.
    Revenue for the second quarter increased 60 percent from the same period a
year earlier due to a 39 percent increase in sales volume and a 16 percent
increase in the average selling price.  The improvement in average selling
price was attributable to a price increase that went into effect on
January 1 and an increase in sales of the company's premium-priced,
high-strength products.  While higher natural gas prices caused manufacturing
costs to increase over last year's second quarter, gross profit margins
improved due to the higher sales prices and record production levels in the
company's manufacturing operations.  Selling, general and administrative
expenses increased as compared to the second quarter of last year because of
expenses that vary directly with sales volume; however, expenses as a
percentage of revenues declined from 14 percent to 10.3 percent.
    Boosted by increases in both sales volume and average selling price, year
to date revenues increased 58 percent compared to the six months ended
June 30, 2000.  Despite higher prices paid for natural gas in the company's
manufacturing operations, gross profit margins improved from the previous year
due to the rise in the average selling price of its products and improved
efficiency in manufacturing.  While selling, general and administrative
expenses increased by $1.4 million from the same period a year earlier,
expenses as a percentage of revenues declined from 13.4 percent to
10.5 percent.
    Mark Pearson, President and Chief Executive Officer of CARBO Ceramics,
stated, "Our results for the second quarter reflect the continuing strong
drilling activity in the North American natural gas industry as well as the
increasing success of our technical marketing program.  The recent decline in
natural gas prices benefits us in the form of lower manufacturing costs and we
have seen no reduction in drilling activity as a result of the lower commodity
prices.  While we did see a normal seasonal decline in activity in Canada, our
sales into that region were 177 percent higher than in last year's second
quarter.  We expect the demand for our products to remain strong for the
remainder of the year and continue to  believe that our biggest challenge for
the future is adding capacity to meet growing demand."
    The company also announced that its Board of Directors approved the
payment of a dividend of $0.09 per share payable on August 15, 2001 to
shareholders of record on July 31, 2001.
    As previously announced, a conference call to discuss the company's second
quarter results has been scheduled for Friday, July 13, at 8:00 a.m. central
time.  The call can be accessed live or on a delayed basis via the company's
