US Ecology to Acquire Stablex Hazardous Waste Facility for $80 Million Canadian Dollars

Purchase Expands Service Offering and Geographic Reach in Canada and Northeast U.S.


BOISE, ID--(Marketwire - September 13, 2010) -  US Ecology, Inc. (NASDAQ: ECOL) ("the Company") today announced that it has entered into a definitive share purchase agreement to acquire Stablex Canada, Inc. ("Stablex"), a leading North American provider of hazardous waste services, for $80 million Canadian dollars ("CAD") cash. The transaction is expected to close on October 31, 2010 and is subject to normal and customary closing conditions, including a purchase price adjustment based on working capital.

Stablex operates a permitted hazardous waste processing and disposal facility in Blainville, Québec, about 30 miles northwest of Montreal, Canada. The rail served facility has been in continuous operation since 1983 and utilizes proprietary technology to treat a wide range of hazardous waste. The Stablex facility principally serves the eastern Canadian and northeastern U.S. industrial markets and employs approximately 150 people. In 2009, Stablex had revenue of $38.5 million CAD. 

"The addition of this superior facility to US Ecology's family of permitted facilities provides us with a northeastern presence and an exceptional service platform to better serve key North American hazardous waste markets," stated US Ecology's Chief Executive Officer and President, Jim Baumgardner. "The Stablex facility will allow us to enhance our service offering, bid and win more event work, and increase penetration of key National Accounts," added Baumgardner.

The definitive share purchase agreement ("Agreement") provides for the purchase of all of the outstanding shares of Stablex from Marsulex, Inc. (TSX: MLX), a Toronto, Ontario based provider of industrial services. The purchase is being funded through a combination of cash on hand and borrowings under a $75 million revolving acquisition credit facility.

"This acquisition of Stablex, along with our pending acquisition of the Siemens facility in Vernon, California, is consistent with our business strategy to acquire facilities that increase our geographic footprint, augment services to existing customers, and attract new customers," Baumgardner concluded.

While the acquisition is expected to contribute solidly to earnings in 2011 and beyond, the Company expects to recognize non-recurring transaction and transition costs associated with the acquisition of approximately $0.07 per fully diluted share in 2010. Excluding these non-recurring transaction costs, the Company remains on track to report full year earnings of between $0.57 and $0.67 per diluted share, unchanged from previous 2010 guidance.
