AECOM.

Twenty-five years ago, AECOM was formed when a handful of Ashland Inc. employees shared a dream of creating an industry-leading firm dedicated to making the world a better place.

On April 6, 1990, AECOM became an independent company formed by the merger of five Ashland entities. While our official founding was in 1990, some of our predecessor firms had distinguished histories dating back more than 110 years.

Since then, more than 50 companies have joined AECOM and, in 2007, we became a publicly traded company on the New York Stock Exchange (NYSE: ACM).
