Allotment Overview Calculated

Total Subscription Fees vs Public Offering Raise Amount

Subscription Tier Analysis Model prediction

Expected Lots Allotted by Subscription Tier

Pool A applications , Pool B applications . Expected lots allotted = "Approximate percentage of total shares applied for" as stated in the allotment announcement × shares applied ÷ lot size, taken directly from the announcement.

Capital Efficiency by Subscription Tier

Capital efficiency = Expected shares allotted ÷ shares applied × 100, i.e. the original "Approximate percentage of total shares applied for" value from the allotment announcement. The fewer shares applied for, the higher the capital efficiency.

Applicant Distribution by Subscription Tier

The vertical axis uses a logarithmic scale to better observe distribution differences across tiers of varying magnitudes. All four charts share the same x-axis; hover tooltips are synchronized.

Subscription Fee ÷ Allotted Market Value by Tier

Allotted market value = valid applicants × shares applied × (percentage applied for ÷ 100) × offer price; total handling fees = valid applicants × HKD 100; ratio = total fees ÷ allotted market value × 100%. Lower tiers have disproportionately high ratios due to very small allotments; ratios stabilize at higher tiers.

Market Sentiment

The IPO saw overwhelming demand with an oversubscription ratio of 198.72x, signaling intense retail enthusiasm. With a hit rate of only 16.11%, just 1 in 6 applicants secured shares, underscoring the competitive subscription landscape. (This is AI-generated commentary based on historical data. Past patterns do not guarantee future outcomes. Not financial advice.)

Tier Analysis

A notable tier inefficiency exists: an A-tail application of 200,000 lots yields just 0.3704 expected lots, while a B-head application of 300,000 lots delivers 0.8642 expected lots—more than double the allocation for only 50% more lots applied. This large jump makes the B-head tier substantially more efficient per lot, though actual cost efficiency also depends on broker fee structures which vary widely.

Demographics

Mainland Chinese investors dominated participation at 79.6%, highlighting strong northbound interest in this offering. The investor base skewed male (64.2%) with an average age of 41.9, reflecting a typical demographic profile for Hong Kong IPOs. (This is AI-generated commentary based on historical data.
