Forward-Looking Statements: All statements in this press release 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.

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.

Use of Non-GAAP Financial Measure

In addition to the financial measures prepared in accordance with GAAP, we use the non-GAAP financial measure “EBITDA.” EBITDA is defined as net earnings before interest, taxes, depreciation and amortization expense. EBITDA is not a measure of operating performance under GAAP. We believe that the use of this non-GAAP measure helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts. When analyzing our operating performance, investors should not consider this non-GAAP measure as a substitute for net income prepared in accordance with GAAP.

Reconciliation of EBITDA to Net Income Attributable to the Company Calendar Year Ended December 2013
