On July 14, 2014, AECOM and URS made available on their website, aecom-urs.com, the following acquisition fact sheet:

The joining of AECOM and URS will dramatically accelerate the combined company’s core strategy of delivering integrated services around the globe. • The combination greatly enhances AECOM’s capacity to provide integrated delivery capabilities, covering all four components of the infrastructure asset lifecycle — design, build, finance and operate. • URS adds new capabilities and end-market expertise — particularly in energy markets, including oil & gas, nuclear and power, and government services — to AECOM’s global platform. • Combining URS’s deep construction expertise with AECOM’s construction capabilities creates a differentiated service offering that can be leveraged across AECOM’s global platform. • The combination of these two industry leaders creates one of the largest E&C companies in the world. • This combination creates a financially strong competitor with pro forma 2013 revenues of more than US$19 billion, EBITDA of approximately US$1.3 billion and total backlog above US$30 billion based on March 31, 2014, data. Clients of both firms will receive substantial benefits as the combined company will be better positioned to deliver the integrated services that clients increasingly demand. • The combined firm will offer a larger, more diverse, yet integrated, portfolio of services in more places around the world — in more than 150 countries and covering all seven continents. • As AECOM integrates the large-project-delivery capabilities of URS, it will advance its core strategy of becoming a more fully integrated global infrastructure firm. • The combined company will be better positioned, through its global platform, in growing markets, from Asia and Africa to the Middle East and Australia, as AECOM: • Bringing together two companies that have outstanding client relationships with many of the world’s largest industrial and infrastructure customers will position the combined company to win a greater share of client spend. • The combined company’s 95,000 employees, serving clients in more than 150 countries around the world, create an extraordinary talent pool and experience base that few others, in any industry, can match. • Introduces additional engineering and project delivery capabilities to its clients. • Capitalizes on URS’s sector expertise in end markets such as oil & gas, power and federal services. ACQUISITION FACT SHEET

Cautionary Note Regarding Forward-Looking Statements

This document may include “forward-looking statements.” All statements other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws. These forward-looking statements, which are based on current expectations, estimates and projections about the industry and markets in which AECOM and URS operate and beliefs of and assumptions made by AECOM management and URS management, involve uncertainties that could significantly affect the financial results of AECOM or URS or the combined company. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” variations of such words and similar expressions are intended to identify such forward-looking statements. Such forward-looking statements include, but are not limited to, statements about the benefits of the transaction involving AECOM and URS, including future financial and operating results, the combined company’s plans, objectives, expectations and intentions. All statements that address operating performance, events or developments that we expect or anticipate will occur in the future — including statements relating to creating value for stockholders, benefits of the transaction to customers and employees of the combined company, integrating our companies, cost savings, providing stockholders with a more attractive currency, and the expected timetable for completing the proposed transaction — are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained and therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. For example, these forward-looking statements could be affected by factors including, without limitation, risks associated with the ability to consummate the merger and the timing of the closing of the merger; the failure to obtain the necessary debt financing arrangements set forth in the commitment letter received in connection with the merger; the interest rate on any borrowings incurred in connection with the transaction; the impact of the indebtedness incurred to finance the transaction; the ability to successfully integrate our operations and employees; the ability to realize anticipated benefits and synergies of the transaction; the potential impact of announcement of the transaction or consummation of the transaction on relationships, including with employees, customers and competitors; the outcome of any legal proceedings that have been or may be instituted against URS and/or AECOM and others following announcement of the transaction; the ability to retain key personnel; the amount of the costs, fees, expenses and charges related to the merger and the actual terms of the financings that will be obtained for the merger; changes in financial markets, interest rates and foreign currency exchange rates; and those additional risks and factors discussed in reports filed with the Securities and Exchange Commission (“SEC”) by AECOM and URS. AECOM and URS do not intend, and undertake no obligation, to update any forward-looking statement.
