# The King of AI Optical Modules is here! Zhongji Innolight has passed the hearing and is about to list on the Hong Kong Stock Exchange.

According to disclosures by the Hong Kong Stock Exchange, on July 17, 2026, **Zhongji Innolight Corporation Limited (hereinafter referred to as "Zhongji Innolight" or "the Company") passed the hearing**, with Goldman Sachs, CICC, Morgan Stanley, and GF Securities serving as joint sponsors.

The predecessor of Zhongji Innolight's main entity was Longkou Zhongji Electrical Machinery Manufacturing Co., Ltd., founded by Wang Weixiu in June 2005 in Longkou, Shandong. After undergoing shareholding reform, it was renamed Zhongji Equipment. The company was officially listed on the ChiNext Board of the Shenzhen Stock Exchange in April 2012, with stock code 300308; in 2017, the company completed the full acquisition of Suzhou Innolight, founded by returned overseas doctoral student Liu Sheng in 2008, subsequently renaming itself Zhongji Innolight and fully transitioning to high-end optical module business, while remaining listed on the ChiNext Board of the Shenzhen Stock Exchange.

Over the past year, Zhongji Innolight's stock price surged from around 125 yuan to a high of over 1,360 yuan, **accumulating a gain of nearly 10 times**, becoming one of the biggest winners in this round of AI rally in the A-share market. As of the time of writing, Zhongji Innolight (300308.SZ) fell 12.00%, trading at 979.46 yuan, with a total market capitalization of 1.09 trillion yuan.

Technologically, the company achieved mass production of three generations of high-speed optical modules: 400G (2018), 800G (2020), and 1.6T (2023). According to Frost & Sullivan, **its mass production timing led the closest competitors by about half a year**. The company pioneered non-hermetic packaging solutions in 2012 and began mass-producing silicon photonics optical modules in 2017. By 2025, it had become the **world's largest** supplier of silicon photonics optical modules by revenue, with silicon photonics technology products accounting for approximately 70% of high-speed product revenue. The company began laying out coherent technology in 2018, pioneering Coherent Lite technology, and successively showcased the industry's first 800G Coherent Lite optical module, 12.8T XPO optical module assembly, and 6.4T NPO module at the OFC 2025 and 2026 exhibitions. As of March 31, 2026, the company held 506 authorized patents.

Regarding customers, according to public statements by Liu Sheng and multiple reports, **Google** was the company's earliest certified top-tier customer. Cooperation between the two began in 2011, with early 40G optical modules being custom-developed for Google. Google Capital also invested in Suzhou Innolight, which aligns with the cooperation start year of the largest customer mentioned in the prospectus. According to public reports, **Microsoft, Amazon AWS, Meta, and NVIDIA** are also core customers of the company: holding approximately 30% to 40% share in Amazon AWS's 800G procurement, about 50% share in Microsoft's direct procurement system, and becoming one of the main suppliers of NVIDIA's 800G optical modules starting in 2025. In the domestic market, it is an important supplier to **Huawei and Alibaba**.

In terms of sales volume, the company's **optical module delivery volume** increased from 7.5 million units in 2023 to 14.6 million units in 2024, and further to 21.1 million units in 2025, reaching 9 million units in the first quarter of 2026 alone. **The growth in high-speed optical module sales was particularly significant**, increasing from 2.504 million units in 2023 to 14.612 million units in 2025.

Regarding average product pricing, the **average selling price of high-speed optical modules** (excluding taxes) decreased from 2,838 yuan in 2023 to 2,212 yuan in 2024, mainly reflecting the natural downward price trend of the product lifecycle; it then rebounded to 2,333 yuan in 2025 due to product mix upgrades, and further rose to 2,458 yuan in the first quarter of 2026. The average price of medium-to-low speed optical modules gradually declined from 621 yuan in 2023 to 520 yuan in 2025.

In terms of capacity and global layout, as of March 31, 2026, the company's annualized production capacity reached 43.3 million units, representing a 2.9-fold increase compared to 2023. The company operates five major production bases and four R&D centers globally, with offices in Singapore and the United States, and production facilities in Thailand. For the three months ended March 31, 2026, overseas market revenue accounted for more than 90% of total revenue.

Regarding R&D investment, as of March 31, 2026, the company employed 2,292 full-time R&D personnel, including over 1,700 R&D professionals with an average of nine years of industry experience; all core technologies were independently developed. The company is also actively laying out emerging technology directions such as NPO, CPO co-packaging technologies, and XPO ultra-high-density pluggable optical modules, showcasing several industry-first products at the OFC 2026 exhibition.

**Industry Outlook**

 **IPO FOCUS**

According to Frost & Sullivan data, the **total global AI capital expenditure** amounted to approximately $0.9 trillion from 2021 to 2025, and is expected to further increase to $6.1 trillion from 2026 to 2030, more than five times that of the previous five years. As a key technological path to unleash the performance of AI computing clusters, optical interconnection is expected to account for about 5% of global AI capital expenditure in 2025, with long-term potential to rise to about 10%.

According to LightCounting and Frost & Sullivan data, the **global optical interconnection market size** will grow from $24.8 billion in 2025 to $111 billion in 2030, with a compound annual growth rate (CAGR) of 31.6% from 2026 to 2030. The datacom sector is the main driver of market expansion, with its scale expected to expand from $19.4 billion in 2025 to $98.6 billion in 2030, achieving a CAGR of 33.8%, significantly faster than the telecom sector.

Regarding accounts receivable, the company's **trade receivables** increased from 2.64 billion yuan at the end of 2023 to 6.33 billion yuan at the end of 2025, and further to 9.60 billion yuan at the end of March 2026, mainly due to the expansion of revenue scale; however, the trade receivables turnover days continuously shortened from 71 days to 56 days, 53 days, and 37 days during the same period, indicating continuous improvement in collection efficiency. As of May 31, 2026, 80.1% (approximately 7.69 billion yuan) of the trade receivables at the end of the first quarter of 2026 had been settled post-period, and the overall collection risk remains controllable.

Regarding cash flow, the company's **net cash flows from operating activities** increased from 1.85 billion yuan in 2023 to 3.14 billion yuan in 2024, and significantly to 10.88 billion yuan in 2025, reaching 3.36 billion yuan in the first quarter of 2026.

It is worth noting that the matching degree between operating cash flow and net profit narrowed once between 2023 and 2024—operating cash flow accounted for 84.0% of current net profit in 2023, dropping to 58.4% in 2024, mainly because the rapid business expansion led to inventory and trade receivables growing faster than trade payables, occupying more working capital; this gap narrowed significantly in 2025, with operating cash flow recovering to 93.9% of net profit, mainly benefiting from the combined effect of a 430 million yuan increase in trade payables that year and the continuous improvement in accounts receivable turnover days. Operating cash flow in the first quarter of 2026 was approximately 53.1% of the current net profit, mainly related to the temporary occupation of working capital caused by the 192.1% year-on-year surge in revenue that quarter, but considering that the post-period collection ratio has already exceeded 80%, the company's overall collection quality remains healthy.
