#### Cautionary Note Regarding Forward Looking Statements
This Current Report on Form 8-K contains "forward-looking statements" within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Exchange Act, including with respect to the Acquisition. Such forward-looking statements include, but are not limited to, statements regarding: the Acquisition; the parties' ability to satisfy the conditions to the consummation of the Acquisition, including in connection with obtaining the Court approvals, and the expected timetable for the Acquisition; and the anticipated occurrence, manner and timing of the closing of the Acquisition. All statements other than statements of historical facts are forward-looking statements. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "plan," "potential," "predict," "project," "should," "target," "will," "would" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Any forward-looking statements are based on current beliefs and expectations and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in, or implied by, such forward-looking statements.

These risks and uncertainties include, but are not limited to: the Scheme of Arrangement implementing the Acquisition is not sanctioned by the Court; a condition to closing of the Acquisition may not be satisfied (or waived); the ability of each party to consummate the Acquisition; the closing of the Acquisition might be delayed or not occur at all; the diversion of management time and attention from ongoing business operations and opportunities; the response of competitors to the Acquisition; the effect of the Acquisition on the Company's operations and its relationships with its suppliers, business partners, management and employees, including its ability to attract and retain key personnel; the outcome of any legal proceedings that could be instituted against the parties to the Acquisition; the risks inherent in drug research, development and commercialization; disruption in the Company's plans and operations attributable to the Acquisition; changes in the Company's business during the period between announcement and closing of the Acquisition; the effects of the Acquisition on the Company's share price; the risks related to non-achievement of any milestone and that holders of the CVRs will not receive any payments in respect of the CVRs; relationships with key third parties or governmental entities; regulatory changes and developments; and the impact of global macroeconomic conditions, including trade and other global disputes and interruptions, including related to tariffs, trade protection measures, and similar restrictions. For further discussion of these and other risks and uncertainties, see the "Risk Factors" section of the Company's Quarterly Report on Form 10-Q filed with the SEC on May 5, 2026, as well as discussions of potential risks, uncertainties and other important factors, in the Company's most recent filings with the SEC and in other filings that the Company makes with the SEC in the future. There can be no assurance that the Acquisition will be consummated in the anticipated timeframe or at all, that any event, change or other circumstance that could give rise to the termination of the definitive agreement for the Acquisition will not occur or that any product candidates will be approved on anticipated timelines or at all. All forward-looking statements in this Current Report are based on information available to the Company as of the date of this Current Report. The Company expressly disclaims any obligation to publicly update or revise the forward-looking statements, except as required by law.
