Transaction to Enhance Competitive Positioning in Ontario and Increase Reach of Michigan-area Operations

Boise, Idaho – May 3, 2016 – US Ecology, Inc. (NASDAQ-GS: ECOL) (“the Company”) today announced that it has acquired all of the stock of Environmental Service Inc., (“ESI”), an environmental services company based in Tilbury, Ontario, Canada. The new US Ecology Tilbury facility will complement our existing fixed facilities in Michigan and Quebec and allow us to better provide a full range of environmental, field, and industrial services to customers in the region. Terms of the transaction were not disclosed.

ESI, located approximately 45 miles east of Detroit, is focused primarily on hazardous and non-hazardous transportation and disposal, hazardous and non-hazardous waste treatment, industrial services, confined space rescue and emergency response work throughout Ontario. Current capabilities include waste consolidation, chemical treatment, solidification, blending and bulking of hazardous and non-hazardous waste and biological treatment of impacted soils.

“The addition of ESI to US Ecology’s family of permitted waste treatment facilities will enhance our geographic reach in the Canadian market to better meet the needs of our combined customers in the region, while complementing our treatment and disposal assets in Michigan and Québec,” commented Jeff Feeler, US Ecology’s Chairman and CEO. “Our expanding commitment to the Ontario market should provide growth opportunities across our Environmental Services, and Field and Industrial Services businesses.”

The ESI transaction, which closed on May 2, will be reported as part of our Environmental Services segment. Its financial contribution to the Company is not expected to have a material impact on US Ecology’s previously provided 2016 earnings guidance which was reaffirmed on April 28, 2016 in conjunction with the Company First Quarter Earnings.
