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

华芢生物-B IPO attracted overwhelming retail demand, with an oversubscription ratio of 791.95 times, leading to a low hit rate of just 5.44%. This indicates fierce competition for allocations and strong market enthusiasm for this 18A biotech listing. (This is AI-generated commentary based on historical data.

Tier Analysis

A notable tier allocation anomaly exists: 甲尾 (A-tail) applicants with 90,000 shares expected only 0.1375 lots, while 乙头 (B-head) applicants with 100,000 shares expected a significantly higher 0.6003 lots. This extreme disparity suggests that the allocation curve is highly convex at this boundary, making B-head applications disproportionately more efficient for those who can reach the threshold.

Demographics

The applicant pool shows a strong mainland China presence at 64.2%, indicating high cross-border interest in this biotech IPO. Male investors dominate at 63.3%, with an average age of 45.2, consistent with typical HK IPO demographics but with a notably high mainland share.
