are forward-looking statements within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995. These forward-looking statements address, among other things: the expected timing of closing of the Company’s acquisitions; the projected impact of various legal proceedings; the projected effects of recent accounting pronouncements; the proposed merger with American Water; prospects, plans, objectives, expectations and beliefs of management, as well as information contained in this report where statements are preceded by, followed by or include the words “believes,” “expects,” “estimates,” “anticipates,” “plans,” “future,” “potential,” “probably,” “predictions,” “intends,” “will,” “continue,” “in the event” or the negative of such terms or similar expressions. Forward-looking statements are based on a number of assumptions concerning future events, and are subject to a number of risks, uncertainties and other factors, many of which are outside the Company’s control, which could cause actual results to differ materially from those expressed or implied by such statements. These risks and uncertainties include, among others, the effects of regulation, abnormal weather, geopolitical forces, the impact of inflation and supply chain pressures, including those resulting from changes in government fiscal policies and regulations, the imposition of tariffs, the threat of cyber-attacks and data breaches, changes in capital requirements and funding, the success of growth initiatives, including pending acquisitions, changes to the capital markets, impact of public health threats, and the Company’s ability to assimilate acquired operations, as well as those risks, uncertainties and other factors discussed in the Company’s Annual Report on Form
