On the evening of June 10, 2026, an announcement from Chengdu's Shuangliu district propelled the wave of "collective overseas expansion" for China's optical module industry another significant step forward. The board of Eoptolink Technology Inc.,Ltd. (SZSE: 300502) formally reviewed and approved a proposal to issue H-shares and list on the main board of the Hong Kong Stock Exchange.
This optical module leader, with over 90% of its revenue coming from overseas, has officially joined the queue for a Hong Kong IPO. Prior to this, in November 2025, Zhongji Innolight had commenced preparations for its H-share listing. In April 2026, TFC Optical Communication formally submitted its listing application to the Hong Kong Stock Exchange. Consequently, the three optical module giants, dubbed "Yi Zhong Tian" by A-share investors, have all embarked on the path to a Hong Kong listing.
Compared to the often staggering A-share market capitalization of Eoptolink, which hovers around 700-800 billion yuan, the scale of fundraising in Hong Kong appears relatively modest. The proposed H-share issuance will not exceed 8% of the total share capital post-issuance. Even with a 15% over-allotment option, the amount raised would only be in the range of several billion Hong Kong dollars. For a company with 7.7 billion yuan in operating cash flow and nearly 10 billion yuan in annual profit on its books, the urgency to list in Hong Kong raises questions. What is Eoptolink's real strategy?
The answer lies in three key words hidden behind the glossy financial reports of this "rags-to-riches" star company: capacity, R&D, and exchange rates.
The Rise of an 800 Billion Empire
The story of Eoptolink is one of the most straightforward yet inspiring entrepreneurial scripts in Chinese manufacturing. Founder Gao Guangrong, born in 1969 in Leshan, Sichuan, was assigned to the optical communication division of Leshan Radio Factory after graduating from a technical secondary school, where he worked as a technician for nine years. In 1998, he ventured into business, establishing a company in Chengdu to act as an agent for optical communication products. Finding slim profits in reselling others' products, he quickly realized, "Selling others' products might only earn 10 yuan per piece, but developing our own can multiply the profit several times over."
In 2008, Gao Guangrong merged "Guangsheng Communication," which he helped establish, with another company named "Yijielong," giving birth to Eoptolink. Over the next decade, the company faced two critical strategic decisions. The first was the shift from the telecom market to the data communications market. Around 2018, against internal opposition, he steered the R&D focus towards high-speed optical modules for data centers, perfectly timing the cycle of rising capital expenditure from global cloud providers. The second was a diversified bet on technology roadmaps, particularly the 2023 launch of the 800G LPO (Linear-drive Pluggable Optics) module, which eliminated power-hungry DSP chips, slashing power consumption by over 50%.
It was precisely this product that enabled Eoptolink to secure over 60% of Meta and Amazon's 800G LPO orders and enter the supply chain for NVIDIA's GB200 platform. Industry estimates suggest Eoptolink accounts for more than 30% of NVIDIA's optical module orders. In 2025, the company invested 702 million yuan in R&D, building a comprehensive technology matrix covering pluggable modules, LPO/LRO, XPO, NPO, and CPO.
Performance exploded exponentially. In 2025, Eoptolink reported revenue of 24.842 billion yuan, a year-on-year increase of 187.29%, and net profit attributable to shareholders of 9.532 billion yuan, surging 235.89% year-on-year. For the first quarter of 2026, revenue reached 8.338 billion yuan, up 105.76% year-on-year, with a net profit of 2.780 billion yuan, growing 76.80% year-on-year.
The capital market delivered an astonishing return. Starting from a low of around 40 yuan in April 2025, Eoptolink's stock price surged over 13-fold in just over a year. On June 5, it hit an all-time intraday high of 818.38 yuan, with its market capitalization once breaching 810 billion yuan. Based on Gao Guangrong's 6.24% shareholding, his personal wealth has soared to approximately 46.8 billion yuan.
However, standing at the pinnacle of an 800 billion yuan market cap, the true motives behind Eoptolink's Hong Kong listing are far more complex than the simple phrase "global expansion."
Pressures of Capacity, R&D Burn, and Currency Pains
The first major pressure facing Eoptolink stems from production capacity. The 2025 annual report indicates the company's capacity utilization rate exceeded 93%, operating at full load. Orders continue to pour in—management revealed that orders for 1.6T optical modules have increased significantly compared to last year and are expected to grow rapidly quarter by quarter. Yet, the ceiling on capacity is visibly apparent.
The only solution lies in Thailand. The first and second phases of Eoptolink's Thai factory have been officially put into operation. The second phase, completed in early 2025, has been continuously expanding production, with the pace of expansion noticeably accelerating in 2026. Even so, capacity remains tight. The company has explicitly stated that "the Thai factory will continue to expand its scale and construct new facilities to meet order delivery demands." The third phase is not yet operational, offering no immediate relief.
Expansion requires capital. Equipment procurement, factory construction, and personnel recruitment for the Thai production line all demand substantial cash investment. The optical module industry is in a critical phase of a capacity race—whoever expands capacity first can capture the next wave of orders. In this window, falling behind by even one step could mean being left behind by competitors.
Prepayment data provides the most direct evidence of the company's inventory preparation efforts. In Q1 2026, prepayments reached 682 million yuan, a staggering quarter-on-quarter increase of 3,920.83%. This indicates the company is aggressively locking in supplies from upstream—core components like electrical and optical chips are in tight supply, and without advanced payment, securing them is difficult. This preemptive stockpiling also requires massive financial backing.
Furthermore, the pace of technological iteration in the optical module industry is visibly accelerating. The cycle for generational shifts—from 400G to 800G, and from 800G to 1.6T—is getting shorter. Each technological upgrade necessitates massive R&D investment. In 2024 and 2025, Eoptolink's R&D expense growth rates were 201.38% and 74.16%, respectively. Management expects related expenditures to climb further.
This is far from the end. R&D for next-generation products like 3.2T and 6.4T is already underway. Simultaneously, new technology paths like silicon photonics and CPO coexist, and the industry's technological roadmap has not yet converged. For a company aiming to maintain its seat at the table, this isn't about choosing one path; it's about having to place bets on multiple paths—because choosing wrong could mean being completely overtaken by rivals.
While the 700 million yuan R&D investment is a substantial absolute figure, it represents only 2.83% of the 24.8 billion yuan revenue, proving insufficient relative to the demands of the technology race. A key purpose of the Hong Kong fundraising is core technology R&D. While the amount may not be decisively large, during the critical window for technological breakthroughs, every dollar can determine victory or defeat.
The most easily overlooked, yet potentially most critical, pressure on Eoptolink comes from foreign exchange. Overseas revenue accounts for a staggering 96.16% of its total. This is a double-edged sword—overseas markets bring high margins and growth, but also constantly expose the company's profit and loss statement to the risks of currency fluctuations.
In Q1 2026, Eoptolink's financial expenses swung sharply from -33.09 million yuan in the same period last year to 522 million yuan. Exchange losses were the core driver. An annual profit of 9.5 billion yuan was eroded by over 500 million yuan in a single quarter due to forex movements—this vulnerability in profitability is a heavy burden for any listed company.
One of the core values of a Hong Kong listing lies precisely in hedging this exchange rate risk. By raising Hong Kong dollar funds on the HKEX, Eoptolink can directly use HKD for overseas procurement and operational payments, reducing its exposure to USD/CNY exchange rate fluctuations.
Concurrently, a Hong Kong listing platform allows the company to more flexibly allocate global resources—for a company with 96% of its income from overseas, this is not a luxury but a necessity.
From another perspective, Eoptolink's A-share P/E ratio (TTM) is around 75x, placing it on the higher end within the A-share optical module sector. If the H-share issuance valuation is relatively lower, it could exert some pressure on the A-share valuation—this is also one reason for the sharp stock price volatility following the announcement.
The "Yi Zhong Tian" Trio Assembles in Hong Kong: A Collective Defense
Eoptolink is not an isolated case. Zhongji Innolight initiated H-share preparations in November 2025, and TFC Optical Communication submitted its H-share listing application in April 2026. Huagong Tech also filed an application with the HKEX in April this year. The convergence of the "Yi Zhong Tian" optical module trio in Hong Kong is now a certainty.
This is no coincidence but an industry consensus. The optical module industry is in a new phase characterized by a "capacity race, supply constraints, rapid technological iteration, and industry restructuring." Leading companies face highly consistent challenges: capacity expansion requires capital, technology R&D requires capital, exchange rate risks need hedging, and internationalization requires a capital platform. Hong Kong offers a second financing channel beyond the A-share market and provides the flexibility for offshore capital operations.
A deeper reason is that the clients of these companies—Meta, Amazon, NVIDIA, Microsoft—are all global tech giants. While an A-share listing can command high valuations, in the eyes of international customers, a Chinese supplier with a Hong Kong listing platform signifies higher corporate governance transparency and more convenient capital communication channels. A Hong Kong listing is, in essence, a passport to globalization.
Eoptolink's move to list in Hong Kong is a strategic play, but also a risky one. It's strategic because it simultaneously opens up space in three critical dimensions: capacity, R&D, and exchange rates. While the scale of Hong Kong fundraising may not be huge, it addresses urgent, bottleneck issues—the expansion of the Thai factory, R&D for 3.2T modules, and hedging exchange rate risks, each requiring financial and capital platform support.
The risk lies in the fact that market scrutiny of high-valuation companies is never lenient. A weaker-than-expected earnings guidance from Broadcom was enough to trigger a broad correction in the optical module sector. If the H-share issue price falls below market expectations, or if post-listing performance is weak, the potential drag on the A-share valuation cannot be underestimated.
A more profound question remains: As the红利 (dividends) from 800G gradually peak, competition in 1.6T fully unfolds, and the R&D race for 3.2T has already begun, can Eoptolink sustain its technological leadership? As capacity from the Thai factory is gradually released, can it be timely converted into orders and profits? As exchange rate volatility becomes the norm, can the company establish an effective hedging mechanism?
These three questions are what will ultimately determine whether Eoptolink can ascend from its 800 billion yuan valuation to greater heights. The Hong Kong IPO is merely a beginning—the real test begins after the listing.
