The Shenzhen-listed optical modules maker is pursuing an A+H share structure in a deal worth about $7 billion that could be Hong Kong’s biggest listing in seven years and the city’s largest IPO of 2026.
Zhongji Innolight has launched a Hong Kong initial public offering seeking up to HK$55 billion, or about $7 billion, after clearing its HKEX listing hearing on July 17 and publishing post-hearing information. The Shenzhen-listed optical communication modules maker, traded under ticker 300308.SZ, had confidentially filed in April 2026 with an initial $3 billion target. The offering would create an A+H share structure and, if completed at the indicated size, would surpass Luxshare Precision’s $3.1 billion July deal, making it Hong Kong’s largest IPO of 2026 and the city’s biggest new listing in seven years.
