This information (including Exhibit 99.1) is being furnished under Item 7.01 hereof and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and such information shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

Special Note Concerning Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements represent plans, estimates, objectives, goals, guidelines, expectations, intentions, projections, and statements of the Company’s beliefs concerning future events, business plans, objectives, expected operating results, and the assumptions upon which those statements are based. Forward-looking statements include without limitation, any statement that may predict, forecast, indicate, or imply future results, performance, or achievements, and are typically identified with words such as “may,” “could,” “should,” “will,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “aim,” “intend,” “plan,” or words or phases of similar meaning. The Company cautions that the forward-looking statements are based largely on the Company’s expectations and are subject to a number of known and unknown risks and uncertainties that are subject to change based on factors which are, in many instances, beyond the Company’s control. Such forward-looking statements are based on various assumptions (some of which may be beyond the Company’s control) and are subject to risks and uncertainties, which change over time, and other factors, which could cause actual results to differ materially from those currently anticipated. New risks and uncertainties may emerge from time to time, and it is not possible for the Company to predict their occurrence or how they will affect the Company. If one or more of the factors affecting the Company’s forward-looking information and statements proves incorrect, then the Company’s actual results, performance, or achievements could differ materially from those expressed in, or implied by, forward-looking information and statements contained in this press release. Therefore, the Company cautions you not to place undue reliance on the Company’s forward-looking information and statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements are set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 and Quarterly Reports on Form 10-Q for the three months ended March 31, 2025, June 30, 2025, and September 30, 2025, in each case under the section entitled “Risk Factors,” and other documents filed by the Company with the Securities and Exchange Commission from time to time.

The Company disclaims any duty to revise or update the forward-looking statements, whether written or oral, to reflect actual results or changes in the factors affecting the forward-looking statements, except as specifically required by law.
