<li>The vote on 21 July is low-risk as no independent H Shareholder comes close to the blocking stake, which is 4.61% of the outstanding shares (6.20% of H Shares).</li>
<li>The appraised value is HK$19.36, but this is a finger-in-the-sky valuation as it marginally increased from HK$19.30 despite the offeror’s weak 2024 results and limited progress on commercialising its pipeline.</li>
