Goldman Sachs maintains Buy on Innolight and significantly raises earnings forecasts and target price

Overview

This report focuses on Innolight's leading position in the global high-speed optical module market, demand expansion driven by rising AI server rack volumes, migration to 800G/1.6T/3.2T specifications, and increasing penetration of silicon photonics technology. Goldman Sachs believes the company is well positioned to continue benefiting from the AI data center optical interconnect upgrade cycle thanks to its R&D capabilities, customer collaboration, scale-cost advantages, replicable mass-production processes, and stable supply chain.

Core views

The core views are: first, AI servers are expanding from scale-out to scale-up and scale-across, which will drive demand for more high-speed, low-latency, and energy-efficient optical interconnects; second, 800G has become the mainstream specification in large data centers, 1.6T will see meaningful volume ramp-up starting in 2026, and 3.2T is expected to be introduced in 2027; third, a higher mix of silicon photonics modules and migration toward higher-end products will improve revenue mix and gross margin; fourth, the company's market share, capacity expansion, and new product pipeline are expected to support strong growth in 2026-28E.

Analysis framework

The report adopts a top-down approach to estimate global optical module TAM and AI server rack demand, combined with bottom-up forecasts for company shipments, ASP, gross margin, expense ratio, and cash flow, and derives the target P/E multiple and target price using peer P/E, future net profit growth, and operating margin correlations.

Methodology notes

• Valuation methods2027E target P/E multiple method

  Using 2027E P/E as the core valuation basis

  Goldman Sachs raised the target P/E from 34.2x to 35.8x. The target multiple is derived from the correlation between peer P/E and future net profit growth and operating margin, and reflects expectations for the company's earnings growth and operating margin expansion.

• market_sizingGlobal optical module TAM forecast

  Forecasting market size based on high-speed optical module specifications and AI data center demand

  The report forecasts the global optical module market at US$51bn/73bn/69bn in 2026/27/28E, with a particular focus on estimating demand for 800G and above specifications in AI server network upgrades.

• 300308.SZ

  Covered target

  Strengths

  A leading global supplier of high-speed optical interconnect solutions, with first-mover advantages in silicon photonics, strong R&D capabilities, scale-cost advantages, customer collaboration, and a stable supply chain.

  Weaknesses

  High-growth assumptions depend on AI server demand, migration to advanced specifications, capacity expansion, and supply of key components.

  Comparison

  The report states that the company holds leading positions in high-speed optical transceiver segments such as 400G, 800G, and 1.6T, and had a 21.2% global market share by relevant revenue in 2025.

  Risks

  Weaker-than-expected 800G+ demand, slower ramp-up of new components, faster normalization of market share, geopolitics, and worsening component supply.

• Global optical module industry chain

  Demand and valuation backdrop

  Strengths

  AI data center network upgrades are driving demand expansion for 800G, 1.6T, and 3.2T optical modules, while rising silicon photonics penetration creates technology migration opportunities.

  Weaknesses

  There are assumptions for year-over-year ASP declines for products of the same specification, and industry supply-demand, competitive dynamics, and technology route changes may affect profitability.

  Comparison

  The report compares Innolight with peers such as LITE, COHR, FN, Accelink, and Hua Gong on valuation and fundamentals.

  Risks

  The pace of technology migration, customer capex, component supply, and geopolitics could all affect the industry's growth trajectory.

Impact & implications

If the report's assumptions materialize, Innolight will gain dual revenue and profit leverage from AI infrastructure capex, network specification upgrades in NVIDIA rack-scale AI servers, rising silicon photonics penetration, and tight supply-demand dynamics for high-end optical modules. On valuation, Goldman Sachs believes 35.8x 2027E P/E sits between the company's historical mean plus 1SD and its peak, and the sharp target price increase reflects a more optimistic view on earnings growth, operating margin expansion, and leading market position.

Risks

• Demand for 800G and above optical modules is slower or weaker than expected.
• Ramp-up of new optical devices is slower or weaker than expected.
• Market share in 800G and above optical modules normalizes faster than expected.
• Geopolitical risks.
• Deterioration in component supply conditions, limiting shipment growth.

What to watch

• The number of AI server racks and the pace of network specification migration on platforms such as NVIDIA GB200, GB300, Rubin, and Rubin Ultra.
• Shipment volume, ASP, and silicon photonics penetration of 800G, 1.6T, and 3.2T optical modules.
• Whether the company's 2026E capacity expansion progresses as planned and utilization remains within the report's expected 71%-80% range.
• Commercialization progress of new scale-up and scale-across related products, including optical engines, FAU, ELS modules, and OCS switches.
• Whether gross margin improves from 42% in 2025 to 50% by 2028E as projected.
• Whether free cash flow can remain positive and continue to grow amid high capex.
