On August 21, 2026, the Competition and Markets Authority in the United Kingdom responded to a briefing paper submitted by Parent in respect of the

Merger to indicate that it had, at such time, no further questions related to the Merger.

Additionally, in connection with the Merger, on August 27, 2026, the Australian Competition and Consumer Commission published its determination that

the Merger may be consummated, subject to expiration of a 14-calendar day waiting period. The waiting period is scheduled to expire at 10:00 a.m. Eastern Time on September 10, 2026.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K (this “Report”) contains forward-looking statements that

involve substantial risks and uncertainties. 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 possibility that the Company’s stockholders may not approve the adoption of the Merger Agreement; the Company’s receipt of any competing offers or acquisition proposals;

a failure to (or delay in) receiving the required regulatory clearances for the Merger; a condition to closing of the Merger may not be satisfied (or waived); the ability of each party to consummate the Merger; the closing of the Merger 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 Merger; the effect of the Merger and the public announcement of the Merger 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; Parent’s ability to successfully integrate the Company and execute on the

continued development of the Company’s programs following the closing; that all or any of the potential milestone payments pursuant to the contingent value rights to be paid to Company stockholders pursuant to the Merger Agreement will not become

payable in accordance with their terms; the outcome of any legal proceedings that could be instituted against the parties to the Merger; the risks inherent in drug research, development and commercialization; disruption in the Company’s plans and

operations attributable to the Merger; changes in the Company’s business during the period between this announcement and the closing of the Merger; Parent’s evaluation of the accounting treatment of the potential acquisition and its potential

impact on its financial results and financial guidance; the effects of the Merger (or the announcement thereof) on the Company’s stock price; 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 Parent’s and the Company’s periodic reports filed with the U.S. Securities and Exchange Commission. There can be no assurance that the Merger will in fact be consummated. All forward-looking statements in this Report are based on

information available to Parent and the Company as of the date of this Report. Parent and the Company each expressly disclaim any obligation to publicly update or revise the forward-looking statements, except as required by law.
