AECOM Completes Acquisition of Earth Tech

AECOM Technology Corporation (NYSE: ACM), a leading provider of professional technical and management support services for government and commercial clients around the world, announced today that it has completed its acquisition of Earth Tech, Inc., a business unit of Tyco International Ltd. (NYSE: TYC ).

Earth Tech provides consulting, engineering and design, build and operate (DBO) services to waste/wastewater, environmental, transportation and facilities clients globally.

With the acquisition of Earth Tech, AECOM increases its global presence, particularly in the Americas, Europe, Australia and Asia. AECOM also significantly strengthens its water and wastewater business, while augmenting its leadership position in the environmental, facilities and transportation sectors.

“We are delighted to welcome Earth Tech into the AECOM family,” said John M. Dionisio, AECOM president and chief executive officer. “This transaction, which expands our workforce to more than 40,000 professionals around the world, enhances our ability to take advantage of the growing business opportunities that exist in our global end markets. We expect this transaction to benefit our clients, employees, and shareholders.”

AECOM has also completed the divestiture of certain Earth Tech businesses that do not align with its strategic plans and core businesses. Concurrent with the close of the purchase of Earth Tech, AECOM divested Earth Tech’s Water & Power Technologies (WPT) and North American Contract Operations (NACO) businesses and its Mexican operations.

The value of the divested WPT, NACO and Mexico assets noted above, along with the value of certain assets that have been carved out of the sale transaction with Tyco, represent a total of $175 million of the original $510 million transaction value. There remains approximately $50 to $60 million of assets that will be held for sale by AECOM until sale documentation is finalized, all required consents are received and the transactions can be closed.
