Cautionary Note Regarding Forward-Looking Statements

This Current Report ~~contains~~on Form 8-K (“Current Report”) contains statements that are forward-looking and as such are not historical facts. This includes, without limitation, statements regarding the ~~Company’s~~ ~~financial~~estimated ~~position,~~redemption ~~business~~price ~~strategy~~per ~~and~~share at the ~~plans~~Shareholder ~~and objectives of management for future operations~~Meeting. These statements ~~constitute~~ constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. In addition, any statements that refer to our intent to enter into one or more Non-Redemption Agreements in connection with the Meeting and the expected terms of any Non-Redemption Agreements are forward-looking statements. They involve known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by these statements. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. When used in this Current Report, words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “strive,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. When the Company discusses its strategies or plans, it is making projections, forecasts or forward-looking statements. Such statements are based on the beliefs of, as well as assumptions made by and information currently available to, the Company’s management. Actual results and shareholders’ value will be affected by a variety of risks and factors, including, without limitation, international, national and local economic conditions, merger, acquisition and business combination risks, financing risks, geo-political risks, acts of terror or war, and those risk factors described under the “Risk Factors” section of the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2026, the Company’s Quarterly Report on Form 10-Q filed with the SEC on May 15, 2026, subsequent Quarterly Reports on Form 10-Q, in the Extension Proxy Statement filed in connection with the Meeting and Amendment on June 16, 2026 (the “Extension Proxy Statement”) and in other reports the Company files with the SEC. Many of the risks and factors that will determine these results and shareholders’ value are beyond the Company’s ability to control or predict.

All such forward-looking statements speak only as of the date of this Current Report. The Company expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in the Company’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. All subsequent written or oral forward-looking statements attributable to us or persons acting on the Company’s behalf are qualified in their entirety by this “Cautionary Note Regarding Forward-Looking Statements” section.
