PITTSBURGH, PA  –  11/02/2007

Calgon Carbon Corporation (NYSE: CCC) announced results for the third quarter ended September 30, 2007.

The company reported net income of $4.9 million or $0.10 per common share on a fully diluted basis for the third quarter of 2007, as compared to a net loss of $0.5 million or $0.01 per common share on a fully diluted basis for the third quarter of 2006.

For the third quarter of 2007, income from operations was $6.5 million versus $1.5 million for the comparable period in 2006. Results for the third quarter of 2006 included a pre-tax gain of $3.2 million related to an insurance settlement for business interruption which was caused by Hurricane Katrina in 2005.

Net sales for the third quarter of 2007 were $84.9 million versus third quarter 2006 sales of $79.7 million, an increase of 6.5%. Currency translation had a $2.0-million positive impact on sales for the third quarter of 2007 due to the stronger Euro and the British Pound Sterling.

For the third quarter of 2007, sales for the Activated Carbon and Service segment increased by 6.6% versus the third quarter of 2006. The increase was primarily due to higher pricing for activated carbon products and services and higher volume in the industrial process and environmental air treatment markets. Equipment sales increased by 5.9% in the third quarter of 2007 versus the third quarter of 2006. The increase resulted primarily from higher demand for odor control equipment and from systems that utilize ultraviolet light for disinfection of drinking water and wastewater. A 6.9% increase in Consumer sales was attributable to higher demand for activated carbon cloth.

Net sales less the cost of products sold as a percentage of net sales for the third quarter of 2007 was 32.1% versus 26.1% for the third quarter of 2006. The increase was primarily the result of higher pricing and volume on certain carbon and service products.

Selling, administrative and research expenses for the third quarter of 2007 were $16.3 million, a decrease of 8.0% from the third quarter of 2006. The decline was primarily the result of lower legal expenses.

For the third quarter of 2007, the company’s income tax provision was $0.4 million versus $0.1 million for the comparable period in the prior year. The company’s third quarter effective tax rate of 8% reflects a reduction in its estimated annualized effective tax rate from 52% as of June 30, 2007 to 38% as of September 30, 2007, including the third quarter reversal of uncertain tax position liabilities due to statute expirations. The company’s tax rate is also impacted by other factors which include tax liabilities in foreign jurisdictions without benefit of a foreign tax credit in the U.S., the recording of tax contingencies for uncertain tax positions, and the projection of taxable income by jurisdiction.

Net sales for the nine months ended September 30, 2007 were $256.3 million, versus $236.8 million for the comparable period in 2006, an increase of 8.3%. Year to date, foreign currency translation had a $6.2-million positive impact on sales due to the stronger Euro and the British Pound Sterling.

For the nine months ended September 30, 2007, income from operations was $20.1 million, versus $3.4 million for the comparable period in 2006. Net income for the nine months ended September 30, 2007 was $11.4 million, as compared to $0.6 million for the comparable period in 2006. Net income for the nine months ended September 30, 2006 was comprised of a loss of $1.3 million from continuing operations and income from discontinued operations of $1.9 million. Results for the nine months ended September 30, 2006 included pre-tax gains of $5.4 million on the sales of the company’s charcoal and solvent recovery businesses and $8.1-million from insurance settlements related to business interruption and damage at the company’s Pearl River Plant due to Hurricane Katrina.

Fully diluted earnings per share for the nine months ended September 30, 2007 were $0.24, versus $0.01 for the comparable period in 2006. Fully diluted earnings per common share for the nine months ended September 30, 2006 were comprised of a loss of $0.03 from continuing operations and earnings of $0.05 per common share from discontinued operations.

Calgon Carbon’s board of directors did not declare a quarterly dividend.

Commenting on the results, John Stanik, chairman, president and chief executive officer of Calgon Carbon, said, “While we recognize the significant impact that our lower tax provision had on the third quarter results, we are pleased with the progress shown in the quarter. Higher prices on activated carbon and service products, a lower cost structure, and lower legal expenses contributed to improved results year-over-year. These three factors will play a continuing role in achieving year-over-year improvement in the fourth quarter.”
