CXMT Corp., formerly ChangXin Memory Technologies, debuted on Shanghai's STAR Market after raising 66.6 billion yuan ($9.8 billion), marking the second-largest IPO in China's history.123467

Shares skyrocketed nearly 470% on their first day, opening at 49.50 yuan compared to the IPO price of 8.66 yuan, which propelled the company's market capitalization to 3.3 trillion yuan ($487.31 billion).5

This remarkable debut makes CXMT the most valuable company in China, surpassing the Industrial and Commercial Bank of China (ICBC).

Valuation multiples and a well-oversubscribed IPO indicated a strong debut, with only 6.73% of shares freely tradable, potentially leading to significant price volatility.8

HSBC Qianhai Securities noted that the offering could drain liquidity from the broader market, although past tech listings suggest a rebound may follow.

In its IPO prospectus, CXMT reported a 7.67% share of the global DRAM market and an operating profit of 35.43 billion yuan in Q1, up from a loss of 2.83 billion yuan a year earlier.

The company plans to utilize IPO proceeds for memory wafer mass production and R&D to enhance its technological capabilities.9

Theodore Shou, CEO at Yiyi Capital, expressed confidence in CXMT's potential, stating, "I have no doubt the company is going to grow to be a global leader... a global champion in this particular sector."

Additionally, CXMT has gained attention as Apple tests its DRAM for devices sold in China.
