FIRST INTERSTATE BANCSYSTEM INC

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include plans, expectations, goals, projections, and statements about the intended or anticipated effects of the Branch disposition transaction, the plans, objectives, expectations and intentions of the Company, the expected timing of completion of the transaction, and other statements that are not historical facts. Such statements are subject to numerous assumptions, risks, and uncertainties, many of which are outside the control of the Company and could have a material impact on the outcome of the Company’s current expectations.

Forward-looking statements are typically identified by words such as “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “pro forma,” “pipeline” and other similar words and expressions. Forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time. Forward-looking statements speak only as of the date they are made. Because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those anticipated in the forward-looking statements and future results could differ materially from historical performance. They are neither statements of historical fact nor guarantees or assurances of future performance. While there is no assurance that any list of risks and uncertainties or risk factors is complete, important factors that could cause actual results to differ materially from those in the forward-looking statements included under the caption “Risk Factors” in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) for the fiscal year ended December 31, 2024. The Company cautions interested parties that any list is not exhaustive of all possible risk factors and other factors could also adversely affect the Company’s results of operations or financial condition.

Readers are cautioned not to place undue reliance on any forward-looking statements. Except to the extent required by applicable law or regulation, the Company disclaims any obligation to revise or publicly release any revision or update to any of the forward-looking statements included herein or in its filings with the SEC to reflect events or circumstances that occur after the date on which such statements were made.
