(Yicai) June 15 -- Chengxin Memory Technology, China’s leading maker of dynamic random-access memory chips, has had its initial public offering signed off by the country’s securities watchdog, clearing the way for the Chinese mainland’s biggest stock market listing since 2022.

CXMT’s registration to go public on Shanghai’s Nasdaq-style Star Market became effective on June 12. The Hefei-based company plans to raise CNY29.5 billion (USD4.4 billion) by issuing 10.6 billion shares, which would also make it the Star Market’s second-largest IPO.

As the only Chinese integrated devices manufacturer that has achieved large-scale DRAM production, CXMT’s IPO has attracted investment from several leading brokerages, including China Merchants Securities and Huaan Securities, as well as from insurers, through a mix of alternative investment subsidiaries, private equity funds, and industrial funds.

Its listing is expected to further strengthen China’s self-sufficiency in memory chips, while also driving coordinated growth across the full industrial chain, from upstream materials, equipment, and components to downstream applications.

CXMT has three 12-inch DRAM wafer fabs in Hefei and Beijing, giving it the largest production capacity in China and the fourth-largest globally. The firm’s industrial chain includes multiple links, such as equipment, materials, packaging, and testing, and its suppliers include more than 30 mainland-listed firms with a total market value of over CNY3 trillion (USD444 billion).

Last year, CXMT bought CNY11.5 billion worth of raw materials, including CNY4.3 billion of chemicals, CNY1.4 billion of photoresists, CNY980 million (USD145 million) of silicon wafers, CNY590 million of electronic specialty gases, and CNY250 million of target materials.
