Changxin Technology’s IPO subscription—how much can you make if you get one lot?

The issue price is 8.66 yuan. One lot is 500 shares, and the payment after subscribing is 4,330 yuan.
A broker research report provided four valuation scenarios:
If the market cap reaches 1 trillion yuan, one lot can make about 3,100 yuan;
If the market cap reaches 1.5 trillion yuan, one lot can make about 6,900 yuan;
If the market cap reaches 2.3 trillion yuan, one lot can make about 12.9k yuan;
In an extremely optimistic scenario of 4.25 trillion yuan, one lot can make about 27.4k yuan.
The above market-cap ranges correspond to a first-day trading surge after listing in the 70%-600% range.
The market is willing to assign such high valuations mainly because Changxin has filled the gap in A-share DRAM manufacturing leading companies. The company expects first-half revenue of 110 billion to 120 billion yuan in 2025, and attributable net profit of 50 billion to 57 billion yuan; this fund-raising will be used for DRAM production-line upgrades, HBM and automotive-grade storage, as well as research and development of next-generation storage technologies.
However, the 8.66 yuan issue price implies a 2025 diluted P/E ratio of 308.92 times, which is clearly higher than the industry average of 76.32 times.
The above calculations are for reference only and do not constitute any investment advice.
Wishing all the esteemed A-share traders good luck in getting an allocation.
