PITTSBURGH--(BUSINESS WIRE)--August 6, 2015--Calgon Carbon Corporation (NYSE: CCC) announced results for the second quarter ended June 30, 2015.

Income from operations for the second quarter of 2015 was $19.8 million versus $21.3 million for the second quarter of 2014. Net income was $12.6 million for the second quarter of 2015 versus $15.2 million for the comparable period in 2014. On a fully diluted share basis, earnings per common share for the second quarter of 2015 were $0.24 versus $0.28 for the second quarter of 2014.

Net sales for the second quarter of 2015 were $135.5 million, as compared to $145.1 million for the comparable period in 2014. Currency translation had a $6.6 million negative impact on sales for the second quarter of 2015 due to the weaker euro, British pound sterling, and yen.

For the second quarter of 2015, sales for the Activated Carbon and Service segment were $123.6 million, a decline of $6.4 million from the same period a year ago. Excluding a $6.3 million negative impact from currency translation, Activated Carbon and Service segment sales were essentially flat. Sales of FLUEPAC® products to the environmental air market, principally in North America for mercury removal, were substantially higher. This increase was offset by lower demand for virgin and reactivated carbon primarily in the potable water markets in North America and Asia. Sales in the environmental water and food markets were also lower.

Equipment segment sales in the second quarter of 2015 were $9.6 million compared to $11.8 million for the same period a year ago. Higher sales of traditional ultraviolet light systems were more than offset by lower demand for carbon adsorption equipment and ballast water treatment systems.

Sales in the Consumer segment were $2.2 million in the second quarter of 2015 compared to $3.3 million in the second quarter of 2014. The $1.1 million decline was due to fulfillment of a single large order during the prior year second quarter.

Net sales less the cost of products sold (excluding depreciation and amortization), as a percentage of net sales for the second quarter of 2015 was 37.5%, versus 34.4% for the second quarter of 2014. The improvement was attributable to several factors, including a more favorable mix of higher margin activated carbon product sales, lower coal costs, and the impact of the Company’s focus on cost and operational efficiency improvements. In addition, the second quarter of 2015 included a $1.2 million, or an approximate one percentage point benefit related to an import duty refund in conjunction with the Trade Preferences Extension Act of 2015 that was signed into law on June 29, 2015.

Selling, administrative and research expenses for the second quarter of 2015 were $22.6 million versus $21.2 million for the comparable period of 2014. The increase was primarily due to the Company’s SAP re-implementation project to improve the functionality of its enterprise resource planning system which went live in July 2015. Expenses related to certain outside consulting services were also higher.

The income tax rate for the second quarter of 2015 was 34.2% versus 27.3% for the second quarter of 2014. The tax provision for the second quarter of 2014 was favorably impacted by a $1.4 million income tax benefit resulting from the conclusion of an Internal Revenue Service examination related to the Company’s 2008 amended tax return.

The Company continued its open market stock repurchase program and purchased 310,881 shares of Calgon Carbon stock during the second quarter. Including the repurchase of an additional 212,210 shares of common stock in July, the Company has repurchased a total of 603,591 shares in the current year, and has approximately $95 million of remaining authorization for common stock repurchases.

On August 4, 2015, Calgon Carbon’s Board of Directors declared a quarterly cash dividend of $0.05 per share, payable on September 15, 2015, to shareholders of record on September 4, 2015.

Commenting on the quarter, Randy Dearth, Calgon Carbon’s Chairman, President and Chief Executive Officer, said, “Our second quarter results demonstrate the positive impact of several Calgon Carbon strategic initiatives. Our ongoing focus on product innovation was a clear catalyst for the continued success of our FLUEPAC mercury control product revenues, as they exceeded our expectations for the quarter. Demonstrating the sustainability of our cost reduction initiatives, our gross margin before depreciation and amortization continued to improve, despite total quarterly revenues that fell shy of our expectations.”

“The second quarter was not without its challenges, as a combination of factors in several of our markets contributed to lower than expected sales. The anticipated level of our oil and gas market activities and projects were negatively impacted by the effects of continued low oil prices and labor disruptions. Quarterly demand from the sweetener, municipal water and environmental water markets were affected by customer order and utilization patterns, including the adverse impact of the unusually wet spring and summer weather conditions in the eastern United States. In addition, revenues in Japan were negatively impacted by increased competitive dynamics in that region.”

“While this quarter’s results exemplify the susceptibility of our products and services to variability in revenue timing on a quarterly basis; our market positioning, market share, and general level of demand for our products and services remains robust across most of our served markets. Accordingly, we expect second half 2015 revenues and profitability to improve sequentially from our first-six-months results as well as year-over-year, including an upward revision to our expected full year revenues of FLUEPAC mercury control market revenues from the forecast we provided in late June.”
