All statements in this communication other than statements of historical fact are "forward-looking statements" for purposes of federal and state securities laws, including any statements of the plans, strategies and objectives for future operations, profitability, strategic value creation, coronavirus impacts, risk profile and investment strategies, any statements regarding future economic conditions or performance, and the expected financial and operational results of AECOM. Although we believe that the expectations reflected in our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in any of our forward-looking statements.

Non-GAAP Financial Information

This press release contains financial information calculated other than in accordance with U.S. generally accepted accounting principles ("GAAP"). The Company believes that non-GAAP financial measures such as adjusted EPS, adjusted EBITDA, adjusted net/operating income, adjusted tax rate, net service revenue and free cash flow provide a meaningful perspective on its business results as the Company utilizes this information to evaluate and manage the business. We use adjusted EBITDA, adjusted EPS, adjusted net/operating income and adjusted tax rate to exclude the impact of non-operating items, such as amortization expense, taxes and non-core operating losses to aid investors in better understanding our core performance results. We use free cash flow to represent the cash generated after capital expenditures to maintain our business. We present net service revenue to exclude subcontractor costs from revenue to provide investors with a better understanding of our operational performance. We present segment adjusted operating margin to reflect segment operating performance of our Americas and International segments, excluding AECOM Capital.

Our non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. A reconciliation of these non- GAAP measures is found in the Regulation G Information tables at the back of this release.
