Press Release

AECOM announced today that its Board of Directors has authorized the repurchase of up to $300 million of its common stock.

“This repurchase authorization reflects our confidence in AECOM’s long-term outlook and the focus of our capital-allocation strategy on driving sustainable returns as we continue to make progress in areas such as balanced growth, profitability and liquidity,” said John M. Dionisio, AECOM chairman and chief executive officer.

AECOM completed its first share-repurchase program, worth $200 million, during the third quarter of its fiscal year 2012.

Any repurchases under the current program will be made at the company’s discretion in the open market or in privately negotiated transactions in compliance with applicable securities laws and other legal requirements and will depend on a variety of factors, including market conditions, share price, the terms of the company’s credit facilities and other factors.
