JX Advanced Metals Plans Significant Expansion of Indium Phosphide Substrate Production, Benefiting from AI Optical Module Demand

Overview

This research report provides a quick commentary on Nikkei news regarding JX Advanced Metals (5016.T) planning to significantly expand Indium Phosphide (InP) substrate capacity. Nomura Securities believes that although not officially confirmed yet, if this plan is true, it will be major good news. Against the backdrop of strong demand for data center optical devices and Chinese export controls, capacity expansion will effectively relieve supply bottlenecks and drive substantial profit growth for the company.

Core views

Nikkei news reports JX Advanced Metals will invest JPY 120 billion to expand InP substrate capacity, reaching total capacity 7-10 times the level as of March 2026 (including ongoing investments), with expectations of hundreds of billions of JPY in operating profit for FY March 2027. In comparison, the company's previously announced plan in February was only 3 times capacity expansion. Regarding supply-demand dynamics, InP substrates are key compound semiconductor materials for light-emitting and receiving elements in optical transceiver modules. JX Advanced Metals holds approximately 40% share in the global external sales market. Due to China's export restrictions on InP used for military purposes, its main competitor AXT (with manufacturing facilities in China) must apply for licenses case-by-case for exports, leading to limited supply. Meanwhile, demand for optical devices in data centers is very strong, causing tight supply-demand for InP substrates. Nomura estimates that since China implemented export controls, average InP substrate prices have increased 2-3 times depending on wafer diameter. Profit potential assessment: JX Advanced Metals is not affected by Chinese export controls, so its capacity expansion has extremely high strategic significance. Nomura believes that given the strength of optical device demand, a capacity increase of up to 10 times is not excessive. Data shows the InP substrate business contributed JPY 6 billion in sales and JPY 1.5 billion in operating profit for FY March 2026. If capacity expansion proceeds smoothly and prices remain high, achieving an operating profit goal of hundreds of billions of JPY in FY March 2027 is feasible.

Analysis framework

Nomura Securities adopted a combination of event-driven analysis and supply-demand framework. First, identify potential capital expenditure changes (from 3 times expected expansion uprated to 7-10 times) through media reports and assess their impact on the supply side. Second, analyze changes in the competitive landscape combining geopolitical factors (Chinese export controls), pointing out the logic that competitors are restricted while the target company benefits. Finally, derive feasibility of future profit growth through volume-price segmentation logic, combining current price appreciation trends (2-3 times) and new capacity release expectations. For valuation, Segmental Valuation Method (SOTP) is used, giving premiums or discounts relative to comparable companies for different business segments.

Methodology notes

• Industry/Industrial Analysis FrameworkSupply-demand framework

  Supply-Demand Framework

  By analyzing changes in the supply side (capacity expansion, supply restriction due to export controls) and demand side (strong demand for data center optical devices), judge product price trends and corporate profit space.

• Valuation MethodSOTP Segment Valuation

  SOTP Segment Valuation

  Divide the company into three sectors: Semiconductor Materials, ICT Materials, Metals and Recycling, refer to P/E ratios of comparable companies for each, give certain premiums or discounts, weight calculation overall reasonable P/E ratio, thereby deriving target price.

• Competition and Strategy Framework

  Competition Reshaping Driven by Geopolitics

  Analyze how geopolitical factors such as export controls change industry competition patterns, allowing unrestricted enterprises to gain market share and pricing power advantages.

• Target PriceJPY 4,500Based on FY2027/3 EPS forecast of JPY 197.9 and 22.8x PE

Impact & implications

The research report suggests that if the expansion plan is true, it will significantly relieve production constraints caused by strong demand, constituting positive good news for JX Advanced Metals. Against the background of being unaffected by export controls, the company is expected to realize leapfrog growth in the semiconductor materials sector profits by seizing market share and leveraging high-price environments. This strengthens its position in the AI data center supply chain.

Risks

• End product (such as smartphones, PCs, servers) demand below expectations
• Metal prices and processing fees deteriorate
• Yen appreciation
• Intensified market competition for main products
• Material demand changes due to semiconductor technology shifts

What to watch

• Actual progress of InP substrate capacity expansion
• Progress of price renegotiation for AI server related products
• Subsequent changes in Chinese export control policies
• Sustainability of data center optical device demand
