Eoptolink Technology files for up to $5B Hong Kong listing as AI infrastructure demand surges

Eoptolink Technology Inc., one of China’s largest manufacturers of high-speed optical transceivers, has filed for a secondary listing on the Hong Kong Stock Exchange. The Chengdu-based company, already listed on the Shenzhen Stock Exchange since 2016, had its board approve the issuance of H-shares on June 11, 2026. The plan involves raising up to 8% of its total share capital, with proceeds earmarked for R&D, capacity expansion, and potential acquisitions.

The numbers behind the hype

The company posted 2025 revenue of 24.84 billion yuan, roughly $3.7B, alongside a net profit of 9.53 billion yuan, approximately $1.4B. That net profit figure represents a 236% increase year-over-year.

The stock has surged nearly 80% year-to-date by mid-2026. Earlier reports from April indicated the company had tapped Citic Securities and JPMorgan to arrange a $3B capital raise. The current $5B target suggests demand from potential investors has come in considerably hotter than initially expected.

Eoptolink manufactures the optical modules that form the nervous system of modern data centers. Its customer list includes Google, Microsoft, and Amazon, all of which rely on the company’s transceivers to move data between servers at high speeds.

What this means for investors

The listing still requires regulatory approval from three bodies: shareholders, the China Securities Regulatory Commission (CSRC), and Hong Kong’s Securities and Futures Commission (SFC).

Eoptolink’s expansion plans, funded by this listing, include potential mergers and acquisitions in the optical transceiver market.
