Ecolab Amends Champion Acquisition Agreement

Ecolab Inc. announced it has amended its acquisition agreement with Permian Mud Service, the parent company of Champion Technologies and Corsicana Technologies (hereafter collectively referred to as Champion), such that Champion's downstream process and water solutions business will be spun-off to Permian's shareholders prior to the acquisition by Ecolab, and Ecolab will not acquire those specific operations. 2011 sales for the downstream business, which primarily serves refineries, were approximately $50 million. Accordingly, the value of the transaction will be reduced to $2.16 billion from $2.2 billion, subject to further adjustment as provided in the acquisition agreement. Ecolab believes the amendment will not have a significant impact on the deal economics, and continues to expect the transaction to deliver approximately $0.12 accretion to adjusted diluted earnings per share in 2013 increasing to approximately $0.50 per share by 2016. Ecolab continues to expect closing of the Champion acquisition to occur by year-end 2012, subject to regulatory clearance and other customary closing conditions. With 2011 pro forma sales of $11 billion and more than 40,000 employees, Ecolab Inc. ECL is the global leader in water, hygiene and energy technologies and services that provide and protect clean water, safe food, abundant energy and healthy environments.
