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. Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in our forward-looking statements include, but are not limited to, the following: our business is cyclical and vulnerable to economic downturns and client spending reductions; limited control over operations that run through our joint venture entities; liability for misconduct by our employees or consultants; failure to comply with laws or regulations applicable to our business; maintaining adequate surety and financial capacity; potential high leverage and inability to service our debt and guarantees; ability to continue payment of dividends; exposure to political and economic risks in different countries, including tariffs; currency exchange rate and interest fluctuations; retaining and recruiting key technical and management personnel; legal claims; inadequate insurance coverage; environmental law compliance and adequate nuclear indemnification; unexpected adjustments and cancellations related to our backlog; partners and third parties who may fail to satisfy their legal obligations; AECOM Capital real estate development projects; managing pension cost; cybersecurity issues, IT outages and data privacy; risks associated with the expected benefits and costs of the sale of our Management Services and selfperform at-risk civil infrastructure, power construction and oil and gas construction businesses, including the risk that any contingent purchase price adjustments from those transactions could be unfavorable and result in lower aggregate cash proceeds and any future proceeds owed to us under those transactions could be lower than we expect; as well as other additional risks and factors that could cause actual results to differ materially from our forward-looking statements set forth in our reports filed with the Securities and Exchange Commission. Any forward-looking statements are made as of the date hereof. We do not intend, and undertake no obligation, to update any forward-looking statement. Non-GAAP Financial Information This communication 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 and adjusted EPS to exclude the impact of certain items, such as amortization expense and taxes 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 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 de termined 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. The Company is unable to reconcile its non-GAAP financial guidance and long-term financial targets due to uncertainties in these non-operating items as well as other adjustments to net income.
