This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements in this Quarterly Report on Form 10-Q include, but are not limited to,

statements concerning our plans, strategies, objectives, expected performance, expenditures, recovery of expenditures through rates, stated on either a consolidated or segment basis, and any and all underlying assumptions and other statements that are other than statements of historical fact. Expressions of future goals and expectations and similar expressions, including "may," "will," "should," "could," "would," "aims," "seeks," "expects," "plans," "anticipates," "intends," "believes," "estimates," "predicts," "potential," "targets," "forecast," and "continue," reflecting something other than historical fact are intended to identify forward-looking statements. All forward-looking statements are based on assumptions that management believes to be reasonable; however, there can be no assurance that actual results will not differ materially.

Factors that could cause actual results to differ materially from the projections, forecasts, estimates and expectations discussed in this Quarterly Report on Form 10-Q include, among other things:

  • our ability to execute our business plan or growth strategy, including utility infrastructure investments;

  • potential incidents and other operating risks associated with our business;

  • our ability to work successfully with our third-party investors;

  • our ability to adapt to, and manage costs related to, advances in technology, including alternative energy sources and changes in laws and regulations;

  • our increased dependency on technology;

  • impacts related to our aging infrastructure;

  • our ability to obtain sufficient insurance coverage and whether such coverage will protect us against significant losses;

  • the success of our electric generation strategy;

  • construction risks and supply risks;

  • fluctuations in demand from residential and commercial customers;

  • fluctuations in the price of energy commodities and related transportation costs or an inability to obtain an adequate, reliable and cost-effective fuel supply to meet customer demand;

  • our ability to attract, retain or re-skill a qualified, diverse workforce and maintain good labor relations;

  • our ability to manage new initiatives and organizational changes;

  • the actions of activist stockholders;

  • the performance and quality of third-party suppliers and service providers;

  • potential cybersecurity attacks or security breaches;

  • increased requirements and costs related to cybersecurity;

  • any damage to our reputation;

  • the impacts of natural disasters, potential terrorist attacks or other catastrophic events;

  • the physical impacts of climate change and the transition to a lower carbon future;

  • our ability to manage the financial and operational risks related to achieving our carbon emission reduction goals, including our Net Zero Goal (as defined below);

  • our debt obligations;

  • any changes to our credit rating or the credit rating of certain of our subsidiaries;

  • adverse economic and capital market conditions, including increases in inflation or interest rates, recession, or changes in investor sentiment;

  • economic regulation and the impact of regulatory rate reviews;

  • our ability to obtain expected financial or regulatory outcomes;

  • economic conditions in certain industries;

  • the reliability of customers and suppliers to fulfill their payment and contractual obligations;

  • the ability of our subsidiaries to generate cash;

  • pension funding obligations;

  • potential impairments of goodwill;

  • the outcome of legal and regulatory proceedings, investigations, incidents, claims and litigation;

  • compliance with changes in, or new interpretations of applicable laws, regulations and tariffs;

  • the cost of compliance with environmental laws and regulations and the costs of associated liabilities;

  • changes in tax laws or the interpretation thereof;

  • and other matters set forth in Item 1, "Business," Item 1A, "Risk Factors" section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, and Part I, Item 2, "Management’s Discussion and Analysis of Financial Condition and Results of Operations," of this report, some of which risks are beyond our control.

In addition, the relative contributions to profitability by each business segment, and the assumptions underlying the forward-looking statements relating thereto, may change over time.

All forward-looking statements are expressly qualified in their entirety by the foregoing cautionary statements. We undertake no obligation to, and expressly disclaim any such obligation to, update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events or changes to the future results over time or otherwise, except as required by law.
