AMEC and MACTEC combine to create a powerful environmental and infrastructure engineering services business of over 7,000 people

May 18, 2011

AMEC, the international engineering and project management company, announces today that it has agreed to buy MACTEC, a leading engineering and environmental services company, for a cash consideration of US$280 million.

Headquartered in Alpharetta, Ga., MACTEC has some 2,600 employees, mostly highly skilled technical professionals, and 70 offices, the majority of which are in the Eastern U.S. It provides a similar wide range of services to AMEC’s existing Earth & Environmental (E&E) business, including environmental planning, assessment and remediation, infrastructure engineering, water resources and construction support services. MACTEC has a high quality, long term, public and private sector client base and provides a broad range of environment and infrastructure services to the energy, commercial/industrial, transportation/infrastructure and federal sectors. In North America, E&E has a strong presence in the Western U.S. and in Canada, so the combination allows AMEC greater access to new clients and regions and MACTEC a better international platform for growth.

Neil Bruce, Chief Operating Officer of AMEC, said: “This acquisition is fully aligned with AMEC’s Vision 2015 growth strategy and provides us with the right scale to service this important and growing environmental and infrastructure engineering services market.”

Hisham Mahmoud, President of AMEC’s E&E business, added: “MACTEC and E&E have a complementary client base and service offering, with minimal overlay in geographic coverage. Our combined business significantly enhances our competitive position in the U.S. market and is in line with our strategy of global geographic expansion.”

Ann Massey, President and Chief Executive Officer of MACTEC said: “We are very excited to add MACTEC’s technical capability, resources, and customer base to AMEC’s successful business. Together, we offer a strong, global platform of consulting, engineering, and project management expertise. The close alignment between our companies’ cultures, services and expertise will provide immediate value to our clients and foster future growth.”
The combined E&E business will be headquartered in Alpharetta and led by Hisham Mahmoud. It will have more than 7,000 employees around the globe and bring AMEC’s total North American workforce to almost 14,000. Ms. Massey and her management team are expected to remain with the combined entity and contribute to its continued growth.
