Shenzhen Longsys Electronics flat in Hong Kong debut after $903 million IPO

Shares of Shenzhen Longsys Electronics (HK:9976) began trading unchanged in Hong Kong on Tuesday. The memory-module manufacturer had raised HK$7.08 billion (about $903 million) through an expanded share offer, as investors weigh the appeal of artificial-intelligence-linked semiconductor listings while memory prices rally.

The stock opened at HK$236, matching its initial public offering price, and held that level during early trading in Hong Kong. The debut follows Longsys’ sale of roughly 30 million shares after underwriters fully exercised a greenshoe option that expanded the offering by 15%.

Longsys set the IPO price 44% below the stock’s last closing price on the Shenzhen exchange, where the company has been publicly traded since 2022.

Longsys, one of the world’s biggest independent producers of memory modules, joins a cohort of AI supply-chain firms that are capitalizing on Hong Kong’s strong stock market.

The listing arrives at a moment when market participants are questioning whether robust AI infrastructure spending can keep memory prices and semiconductor valuations at current highs.

Hong Kong initial public offerings have generated more than $45 billion this year as of early 2026, ranking 2026 as the third-best year ever for IPO proceeds in the city.

For the ten IPOs of comparable size or larger, the weighted average first-day return has been approximately 5%, and more than half of those listings are currently trading below their offer prices.

The IPO also underscores worries about constrained memory availability. Prices for DRAM and NAND have climbed sharply so far this year, and robust AI demand is projected to shrink the DRAM allocations that module makers can access in 2027, according to Rolf Bulk, head of semiconductors and infrastructure at The Futurum Group.

In response, Longsys has about doubled its advance payments to suppliers over a six-month span in anticipation of tighter supply, Bulk noted.

Cornerstone investors took up 18.89% of the offering, among them Transsion International, CITIC Securities Asset Management and Lens Technology HK.

Longsys intends to use the net proceeds to support research and development in chip design and next-generation memory technologies.

For the first half of this year, Longsys’ revenue more than doubled to 24.1 billion yuan, and net profit soared more than 700 times to 10.6 billion yuan, driven by rising memory prices.
