***Forward-Looking Statements***

The press release attached as Exhibit 99.1 hereto and the statements contained therein include "forward-looking" statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, which statements involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or the Company's future financial or operating performance. In some cases, you can identify these statements because they contain words such as "may," "will," "believes," "expects," "anticipates," "estimates," "projects," "intends," "should," "seeks," "future," "continue," "plan," "target," "predict," "potential," or the negative of such terms, or other comparable terminology. Such statements include, without limitation, statements regarding the Business Combination, the expected listing of the combined company's common stock on the NYSE American LLC (the "NYSE American") under the ticker symbol "AIB," and the anticipated benefits of the Business Combination. Forward-looking statements relating to expectations about future results or events are based upon information available to the Company as of today's date and are not guarantees of the future performance of the Company, and actual results may vary materially from the results and expectations discussed. The Company's expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks, uncertainties and other factors that could cause actual results to differ materially from those projected, including, without limitation, the parties' ability to complete the transaction and integrate their respective businesses into a combined publicly listed company post-merger, the occurrence of any event, change or other circumstances that could prevent the common stock of BlockchAIn from commencing trading on the NYSE American at 9:30 a.m. EDT on March 17, 2026 or, subsequently, of continuing to trade on such market or of qualifying to trade on any securities trading market, the parties' ability to obtain sufficient funding to maintain operations and develop additional services and offerings, market acceptance of the parties' current products and services and planned offerings, competition from existing or new offerings that may emerge, impacts from strategic changes to the parties' business on net sales, revenues, income from continuing operations, or other results of operations, the parties' ability to attract new users and customers, the parties' ability to retain or obtain intellectual property rights, the parties' ability to adequately support future growth, the parties' ability to comply with user data privacy laws and other current or anticipated legal requirements, and the parties' ability to attract and retain key personnel to manage their business effectively. These risks, uncertainties and other factors are described more fully in the section titled "Risk Factors" of the Registration Statement on Form S-4 filed by BlockchAIn with the SEC in connection with the proposed Business Combination on December 1, 2025, as amended on December 23, 2025, January 21, 2026, January 22, 2026, January 30, 2026, and February 17, 2026, which was declared effective by the SEC on January 30, 2026, and in the Proxy Statement/Prospectus. See also the section titled "Risk Factors" in the Company's periodic reports which are filed with the SEC. These risks, uncertainties and other factors are, in some cases, beyond the parties' control and could materially affect results. If one or more of these risks, uncertainties or other factors become applicable, or if these underlying assumptions prove to be incorrect, actual events or results may vary significantly from those implied or projected by the forward-looking statements. No forward-looking statement is a guarantee of future performance. All subsequent written and oral forward-looking statements concerning the Company, BlockchAIn, One Blockchain, or any of their affiliates, or other matters and attributable to the Company, BlockchAIn, One Blockchain, any of their affiliates, or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above.
