AXT stock surges 8,436% on AI data centre demand
The company’s supply of gallium arsenide and indium phosphide substrates positions it at the core of optical networking, driving a record backlog and debt-free balance sheet despite trade risks.
Semiconductor materials manufacturer AXT has delivered an 8,436% one-year return as investors capitalise on the AI infrastructure boom. The company supplies gallium arsenide, indium phosphide, and germanium substrates essential for optical networking in data centres. Driven by massive capital expenditure from Big Tech firms including Amazon, Microsoft, Alphabet, and Meta, AXT reported a 38.6% year-on-year revenue increase to $26.9 million in the first quarter and a record $100 million backlog. Despite its small size and exposure to cyclical demand and trade tensions with China, the company maintains a debt-free balance sheet and holds a consensus 'Moderate Buy' rating from analysts.
The surge in AXT’s valuation reflects a broader market recognition that AI infrastructure spending extends beyond graphics processing units to include connectivity and semiconductor materials. Major technology firms are expected to spend as much as $725 billion combined on capital expenditures this year, with significant portions directed toward data centres and networking hardware. Amazon, Microsoft, Alphabet, and Meta are leading this charge, with individual spending plans ranging from $135 billion to $200 billion. This capital expenditure cycle has transformed AI infrastructure from an experimental area into a mandatory component of tech strategy, creating sustained demand for the materials AXT produces.
AXT’s financial performance has mirrored this shift in demand. The company reported a 38.6% year-on-year revenue increase to $26.9 million in the first quarter, alongside a record backlog of $100 million. For the full year 2025, AXT recorded total revenue of $88.3 million with a GAAP gross margin of 12.7%. The company’s market capitalisation has reached $7.52 billion, a significant increase from its previous status as a forgotten small-cap semiconductor supplier. The improvement in gross margin to 29.6% in the first quarter, up from 20.9% a year earlier, further underscores the company’s operational recovery and pricing power.
A key differentiator for AXT is its financial discipline, particularly its debt-free balance sheet. In an environment where many speculative AI plays have funded expansion through expensive borrowing or repeated share offerings, AXT has avoided both pitfalls. This financial stability is attractive to investors seeking exposure to the AI theme without the leverage risks associated with other small-cap semiconductor suppliers. The company’s manufacturing operations in China, however, present exposure to trade tensions, a risk that analysts continue to monitor closely.
Wall Street analysts maintain a consensus 'Moderate Buy' rating on AXT, with a mean price target of $87.75, representing a 29% downside from current levels. The high target of $95 indicates a 23.25% downside, suggesting that analysts believe the stock’s valuation has caught up to the AI-related networking demand. The primary question for investors is whether AXT can translate AI enthusiasm into sustained earnings growth rather than temporary order spikes. The company’s ability to navigate cyclical demand and geopolitical risks will be critical in determining if its current valuation is justified.
