URS is a leading engineering, construction and technical services firm with approximately 50,000 employees serving public and private sector clients in nearly 50 countries with $11 billion in revenue. “I’m delighted to share this exciting news with our employees around the world,” said Michael S. Burke, AECOM president and chief executive officer. “By bringing together the talented people of AECOM and URS, we will be able to deliver an unrivaled array of solutions to the clients of both firms.” The combination is a transformational union of the world-class capabilities and people of AECOM and URS, reflecting a dramatic acceleration of AECOM’s strategy to create an integrated-delivery platform with superior capabilities to design, build, finance and operate infrastructure for clients around the globe. “This is more than a strategic transaction,” said Burke. “This is a statement that we intend to seize upon our company’s full potential as we continue to play a leading role in the ongoing improvement and development of the world we live in. I am confident that this transaction will offer our employees the greatest set of professional opportunities in our industry, and will help all of us achieve our highest career aspirations.” Images, here and below, show examples of projects that have benefited from services of both AECOM and URS, including the World Trade Center complex in New York City, United States.

2 URS adds to AECOM’s construction capabilities, deepening a core competency that AECOM will be able to leverage across its global platform. URS also brings strong sector expertise in important end markets, including oil & gas, power and government services. “We are now embarking on a bold journey — one that will completely alter the landscape of our industry; one that will represent great things for our people and our clients; and one that will considerably strengthen our ability to deliver the global projects that are vital for creating, enhancing, and sustaining the world we live in.” The new AECOM will be better positioned to serve major clients, who are increasingly demanding integrated capabilities covering all four components of the infrastructure asset lifecycle — design, build, finance and operate. The combined company will be a leading, fully integrated infrastructure and support services provider, with over 95,000 employees in more than 150 countries. The combined firm would rank in the top 150 among the Fortune 500, based on 2013 revenues of more than US$19 billion. “On a personal note, I want to thank all AECOM employees, whose dedication and commitment to our success provided the foundation for this opportunity,” said Burke. “Over the past decade, we have grown steadily and built an organization that has become a global leader across all of our markets. Along the way, we have welcomed more than 40 new companies into the AECOM family, expanding our services portfolio, extending our geographic reach, and cementing our technical and professional excellence across all the markets that we serve. “Many of you have been part of this journey over the past decade, and contributing to our success for even longer. And while some of you are relatively new to this journey, you equally bring critical experience and valuable new perspectives to our continued progress.” The transaction, which is subject to customary shareholder and regulatory approvals, is expected to close in October. AECOM is developing a detailed integration plan that will be led by executives of both companies, with Kevin Lynch, executive vice president and chief strategy officer, providing leadership for AECOM. Until the close of the transaction, AECOM and URS will remain competitors, which means that employees will need to act accordingly. A separate message from Kevin will provide more information on the integration process and expectations. “We will join the best practices, learnings and people from both organizations to create an industry-leading winner for the future. Our new firm will benefit our people and our clients as we create new growth opportunities through our broadened capabilities and unmatched global reach.” A page on myAECOM has been created to provide more information related to this announcement.
