#Why is AXT Inc. Soaring in Stock Value?
AXT Inc. has seen a notable surge in its stock price, jumping approximately 10% as investors react to potential impacts from China's new material export regulations. This shift is largely driven by concerns surrounding indium phosphide, a crucial semiconductor material that facilitates optical interconnects in artificial intelligence data centers. The Chinese government has established permitting requirements for overseas shipments of indium phosphide that took effect on February 4, 2025, and these permits have not been issued in a timely manner.
#What Do the Export Controls Mean for InP Supply?
The recent supply constraints have resulted in a staggering 250% price increase for 6-inch indium phosphide wafers, pushing prices up to around $5,000 each. AXT and Japan’s Sumitomo Electric hold significant sway over the market, controlling nearly 80% of the global supply of this essential substrate. While AXT's primary production facility in Beijing Tongmei Xtal Technology received initial export permits in June 2025, the company continues to experience permitting delays extending into 2026, presenting a substantial challenge to its business operations.
#How is AXT Adapting to the Changing Market?
AXT’s revenue distribution in North America has sharply declined, falling from 8% in 2024 to around 2% in 2025. The company recognizes the fundamental role of indium phosphide in AI infrastructure, as this material is vital for manufacturing photonic chips used in high-speed communication across data centers. Customers like Coherent and Lumentum, which provide optical components relied upon by large-scale tech firms, are already facing lengthy production backlogs due to these complications.
#What Strategies is AXT Pursuing?
In response to these challenges, AXT is promoting its local supplier model as a safeguard against Chinese export restrictions. By vertically integrating through its subsidiary Tongmei, AXT seeks to enhance reliability in sourcing materials, which contrasts sharply with competitors that depend on third-party Chinese suppliers. Additionally, AXT is focused on expanding Tongmei’s capacities and is exploring a potential public listing on the Shanghai STAR Market, which could provide funding for further growth and deepen its integration into China's domestic market.
#What Should Investors Consider?
The recent uptick in AXT's stock is indicative of market awareness regarding risks associated with concentrated supply chains in critical materials. With two entities controlling 80% of the global indium phosphide supply and ongoing export regulations, the implications for pricing power are profound. AXT's revenue decline raises concerns about its capability to serve vital markets, as higher wafer prices alone cannot offset reduced sales volumes. For investors evaluating AXT, key indicators to monitor include the timelines for permit approvals and the advancement of the STAR Market listing. Consistent export licenses for Tongmei could lead to significant upside for AXT’s stock, while continued delays may undermine its ability to capitalize on price increases in Western markets.
