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 risk and

uncertainties. 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 Report on Form 10-K for the year ended December 31, 2020, Quarterly

any forward-looking statements to reflect events or circumstances after the date of this presentation or otherwise, and Quanta expressly

disclaims any written or oral statements made by any third party regarding the subject matter of 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 measures should not be considered as

alternatives to GAAP measures, such as net income 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. For a reconciliation to the most

directly comparable GAAP financial measures, please refer to the accompanying reconciliation tables.
