Forward-Looking Statements
This Form 8-K contains “forward-looking statements” within the meaning of the federal securities laws, including safe harbor provisions of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding the proposed acquisition of the Company, regulatory approvals (including the MPUC’s written order), the expected timetable for completing the proposed transaction and any other statements regarding the Company’s future expectations, beliefs, plans, objectives, financial conditions, assumptions or future events or performance that are not historical facts. This information may involve risks and uncertainties that could cause actual results to differ materially from such forward-looking statements. These risks and uncertainties include, but are not limited to: the timing to consummate the proposed transaction; the risk that the conditions to closing of the proposed transaction may not be satisfied; the risk that a regulatory approval that may be required for the proposed transaction is not obtained or is obtained subject to conditions that are not anticipated; and the diversion of management’s time on transaction-related issues.
When used in this Form 8-K, or any other documents, words such as “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “target,” “could,” “goal,” “intend,” “objective,” “plan,” “project,” “seek,” “strategy,” “target,” “may,” “will” and similar expressions are intended to identify forward-looking statements. These forward-looking statements are based on the beliefs and assumptions of management at the time that these statements were prepared and are inherently uncertain. Such forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements. These risks and uncertainties, as well as other risks and uncertainties that could cause the Company’s actual results to differ materially from those expressed in the forward looking statements, are described in greater detail under the heading “Item 1A. Risk Factors” in the Company’s Form 10-Q for the quarter ended June 30, 2025, the Company’s Form 10-K for the year ended December 31, 2024 and in subsequently filed Forms 10-Q and 8-K, and in any other SEC filings made by the Company. Management cautions against putting undue reliance on forward-looking statements or projecting any future results based on such statements or present or prior earnings levels. Forward-looking statements speak only as of the date hereof, and the Company does not undertake any obligation to update or supplement any forward-looking statements to reflect actual results, new information, future events, changes in its expectations or other circumstances that exist after the date as of which the forward-looking statements were made.
