ZJ Innolight profit jumps 242% on AI optical module demand

ZJ Innolight reported H1 2026 net profit of RMB13.651 billion, up 241.7% year over year, as AI infrastructure spending drove optical module shipments.

The company attributed the surge to major customers increasing investment in AI infrastructure and rapid growth in shipments of its 800G and 1.6T optical modules, according to the interim results announcement.

Revenue reached RMB41.778 billion, up 182.5% from a year earlier. Gross profit rose 234.6% to RMB19.138 billion, with overall gross margin at 45.8%, up 7.1 percentage points, reflecting higher revenue contribution from high-speed optical modules carrying relatively stronger margins. Earnings per share came in at RMB12.31.

The board declared an interim dividend of RMB12 per 10 shares. Shares of the Hong Kong-listed company rose 3.73% on the day, with short selling at HK$63.95 million, a 5.756% ratio.

The results place ZJ Innolight among the biggest beneficiaries of the AI infrastructure buildout. The company, which also trades on the Shenzhen Stock Exchange under 300308.SZ, supplies high-speed optical transceivers used in data centers supporting AI workloads. Its dual listing gives investors exposure to the optical component supply chain through both mainland and Hong Kong markets.

The 800G and 1.6T product lines have become the primary growth engine, with hyperscalers and cloud providers accelerating capital expenditure on AI compute clusters. The gross margin expansion of 7.1 percentage points indicates the product mix shift toward higher-speed modules is improving profitability. The company's revenue growth of 182.5% outpaces the broader optical module sector, reflecting its position as a leading supplier to AI data center operators.

The interim results follow a period of sustained demand for high-bandwidth connectivity in AI training and inference infrastructure. Optical modules are critical components in data center networks, transmitting data between servers and GPU clusters at speeds that copper cabling cannot match. As AI models grow in size and complexity, the demand for higher-speed optical interconnects has accelerated, pushing the industry from 400G toward 800G and 1.6T generations.

The optical module market has become one of the most competitive segments of the AI hardware supply chain, with manufacturers racing to deliver higher-speed transceivers to meet data center demand. ZJ Innolight's results suggest the transition to 800G and 1.6T modules is accelerating, with the company capturing a significant share of this growing market as hyperscalers scale AI compute capacity.

The company did not disclose full-year guidance in the interim announcement, and consensus estimates were not immediately available.

The earnings beat confirms that AI infrastructure spending remains a powerful demand driver for optical component suppliers. Investors will watch whether the 1.6T ramp sustains momentum into the second half and whether margin expansion continues as the product mix shifts further toward higher-speed modules.
