How does Cig Shanghai's (06166) Q3 report look amid the AI computing power buildout heating up high-speed optical modules?

In 2026, the construction of AI computing power infrastructure continues to heat up, with global cloud service providers increasing their investment in data centers. As the key infrastructure connecting computing power chips, servers, and data center networks, high-speed optical modules are ushering in a new wave of demand release. Against this industry trend, Cig Shanghai (06166) has delivered its latest financial report. According to the Q3 report, the company achieved substantial growth in both revenue and net profit attributable to shareholders in the first three quarters, with third-quarter standalone performance accelerating further, and the high-speed optical module business becoming the engine driving performance growth. From an industry logic perspective, global AI infrastructure construction continues to drive upgrades in data transmission rates, with 800G optical modules gradually becoming an important product for large-scale deployment, while next-generation products such as 1.6T are also being accelerated. Cig Shanghai's performance growth this time is the result of the combined effects of industry demand, product mix upgrading, customer expansion, and capacity release. As demand for high-speed optical modules continues to grow, can Cig Shanghai leverage this round of AI computing power construction cycle to transform demand growth into long-term performance momentum, and continue to consolidate its advantages in the next-generation optical module market? 800G optical modules ramp up, high-speed optical modules become the main growth driver Breaking down Cig Shanghai's operating performance in the first three quarters, the most prominent feature is the synchronous growth of revenue and profit, with profit-side elasticity being more significant. It is understood that in the first three quarters of 2026, the company achieved operating revenue of RMB4.921 billion, a year-on-year increase of 46.46%; net profit attributable to shareholders of RMB761 million, a year-on-year increase of 193.35%; and net profit attributable to shareholders after deducting non-recurring gains and losses of RMB730 million, a year-on-year increase of 185.95%. Among them, the company achieved operating revenue of RMB2.216 billion in the third quarter alone, a quarter-on-quarter increase of 56.21% compared with the second quarter; net profit attributable to shareholders reached RMB433 million, a quarter-on-quarter increase of 106.71%. In other words, the net profit attributable to shareholders contributed in the third quarter alone has already exceeded the combined profit contributed in the first two quarters of the first half. The core reason why profit growth outpaced revenue growth lies in the optimization of product mix. According to the company's Q3 report, global AI infrastructure construction has driven demand growth for high-speed optical modules, and the proportion of the high-speed optical module business, which has higher profitability, in the overall business has continued to increase. As of the end of Q3 2026, revenue from the high-speed optical module business accounted for more than 50% of the company's operating revenue, with 800G products accounting for the vast majority of high-speed optical module shipments. In the past, Cig Shanghai's business layout covered multiple areas including telecom broadband access equipment, wireless network access equipment, and optical modules, with a certain degree of diversification. With the acceleration of AI data center construction, high-speed optical modules have gradually become the core DRIVE of the company's performance growth. Compared with traditional communication equipment businesses, high-speed optical modules have higher technical requirements, faster product iteration, and higher customer certification thresholds. An increase in their business proportion helps optimize the company's overall revenue structure and provides support for profit margin improvement. It is understood that Cig Shanghai's optical module products cover interconnect rates such as 100G, 400G, 800G, and 1.6T, and the company has laid out technology directions including silicon photonics, LPO, and CPO. The company has previously showcased 800G OSFP and LPO products, and is advancing customer testing of 1.6T optical modules as well as prototype development of CPO optical engines. These layouts mean the company is preparing for the next generation of technological evolution. Of course, transforming technological reserves into actual performance still requires going through customer validation, product introduction, large-scale production, and yield improvement. Therefore, reasonable expectations should be given to directions such as 1.6T and CPO, but R&D samples and customer testing should not be conflated with large-scale commercial shipments. At the current stage, 800G has become the main support for the company's high-speed optical module shipments, and future growth still requires close observation of the mass production progress of new products. In terms of customer structure, according to the Q3 report, the company has achieved important breakthroughs in new customer expansion in the North American market, with the customer structure gradually expanding from mainly network equipment suppliers to different types of customers such as traditional cloud service providers, emerging cloud computing companies, and computing power infrastructure service providers. This change is worth noting. As AI computing power demand spreads from chip manufacturers to cloud service providers, data center operators, and professional computing power infrastructure service providers, the number of procurement entities in the industry chain is increasing. Cig Shanghai's ability to enter the supply systems of more types of customers is conducive to expanding potential market space and also helps reduce dependence of business growth on a single customer group. Overall, the core highlight of Cig Shanghai's third-quarter performance is that high-speed optical modules have grown from an important business segment into a core business accounting for more than half of the company's revenue, with 800G shipments providing real performance support, indicating that the company is transforming from a traditional communication equipment supplier into a participant in the AI high-speed optical interconnect industry chain. Stepping up capacity and supply chain layout, improving AI optical interconnect industry chain capabilities Currently, as product rates upgrade from 400G to 800G and 1.6T, the manufacturing process places higher demands on precision equipment, optical components, chip packaging, testing capabilities, and supply chain coordination. Enterprises not only need product R&D capabilities, but must also have sufficient production capacity and a stable delivery system to truly undertake continuously growing orders from major customers. Looking at capacity construction in recent years, Cig Shanghai's Shanghai No. 2 factory in Jiashan has a total construction area of approximately 100,000 square meters and was put into production in July 2025, with the company planning to gradually increase output and utilization. At the same time, the company adopts a production model combining its own factories with collaborative manufacturing, maintaining control over product design, key materials, and core processes while leveraging partners' production space and supply chain resources to improve delivery efficiency. From the balance sheet in the Q3 report, as of the end of September 2026, the company's construction in progress reached RMB1.552 billion, a substantial increase from RMB458 million at the end of 2025; fixed assets reached RMB1.100 billion, further increasing from the beginning of the year. The company's total assets reached RMB15.184 billion, a year-on-year increase of 27.53%, reflecting continued increases in investment in production facilities and related assets during business expansion. In addition, according to the use of proceeds previously disclosed in the company's prospectus, approximately 55% of net proceeds will be used to enhance optical module product capacity, approximately 30% for strategic investment in selected upstream enterprises, and the remaining approximately 15% for general corporate purposes and supplementing working capital. By enhancing capacity and making strategic investments in selected upstream enterprises, the company is expected to further strengthen supply chain coordination capabilities. From this perspective, Cig Shanghai's growth logic is no longer limited to simple product sales, but is gradually extending to comprehensive competition in capacity, technology, and supply chain coordination capabilities. For Cig Shanghai, the more important indicators to watch going forward are whether 800G product shipments can maintain growth, whether 1.6T products can achieve commercial breakthroughs, whether new North American customers can generate stable revenue, and whether new capacity can effectively improve profitability. Overall, in the first three quarters of 2026, the company not only achieved rapid growth in revenue and profit, but the revenue share of the high-speed optical module business has also exceeded 50%, 800G products have formed large-scale shipments, the customer structure has gradually broadened, and capacity construction and financing layout have advanced in parallel. These changes together constitute an important foundation for the company's medium- and long-term growth. However, from an investment logic perspective, what truly determines the company's future value is not only how large the industry space is, but more importantly whether the company can continue to obtain customer orders, maintain product competitiveness, achieve effective capacity utilization, and transform profit growth into real cash flow. In the next stage, the task the company needs to accomplish is to further consolidate current high growth into stable operating capability.
