This presentation (and oral statements regarding the subject matter of this presentation) includes forward-looking statements intended to qualify under the "safe harbor" from liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements include any statements reflecting Quanta's expectations, intentions, strategies, assumptions, plans or beliefs about future events or performance or that do not solely relate to historical or current facts. Forward-looking statements involve certain risks, uncertainties and assumptions that are difficult to predict or beyond Quanta's control, and actual results may differ materially from those expected, implied or forecasted by our forward-looking statements due to inaccurate assumptions and known and unknown risks and uncertainties. Additionally, while all forward-looking statements are necessarily speculative, Quanta believes that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection extends from the date of preparation. For additional information concerning some of the risks, uncertainties, assumptions and other factors that could affect our forward-looking statements, please refer to Quanta's Annual Reports on Form 10-K for the years ended December 31, 2021 and December 31, 2022 (when filed), Quarterly Reports on Form 10-Q for the quarters ended March 31, 2022, June 30, 2022 and September 30, 2022 and other documents filed with the Securities and Exchange Commission, which are available on our website (www.quantaservices.com), as well as the risks, uncertainties and assumptions identified in this presentation.

Certain information may be provided in this presentation that includes financial measurements that are not required by, or presented in accordance with, generally accepted accounting principles (GAAP). These non-GAAP financial measures should not be considered as alternatives to GAAP financial measures, such as net income attributable to common stock and cash flow provided by operating activities, and may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.
