Harsco Corp. has acquired privately-held Performix Technologies, Ltd., Ohio, a leading producer of specialty additives used by steelmakers in the ladle refining of molten steel. The acquisition is expected to be accretive to Harsco's 2007 earnings. Terms were not disclosed.

Performix operates from two plants in the U.S., serving most of the major steelmakers in the upper Midwest and Canada. The company has more than 30 years of experience in ladle metallurgy, and maintains extensive laboratory facilities to assist customers in determining the optimum Performix product for each ladle.

Harsco expects to expand Performix's value-enhancing product technology into other steelmaking locations served by Harsco throughout the world.

The acquisition closely complements Harsco's National Recovery Systems operations, which Harsco acquired in December 2005 as part of its acquisition of the northern hemisphere steel mill services operations of Brambles Industrial Services. Like Performix, National Recovery Systems also specializes in providing blended materials used in the steelmaking process, recycling steelmaking by-products into briquettes that are recharged back into production for cost-effective and environmentally-responsible reuse.

Performix recorded 2006 sales of approximately $29 million and employs approximately 60 people.

Harsco Corp. is one of the world's leading diversified industrial services companies. The company posted 2006 revenues of $3.4 billion and employs approximately 21,500 people worldwide.
