Rally Builds on Supply Deals and a Profitability Turnaround

AXT (NASDAQ:AXTI) shares extended a powerful rally in pre-market trading Thursday, building on gains from the prior session as investors continue to revalue the company's indium phosphide Business tied to AI-driven optical connectivity demand. AXT is a Fremont, California-based materials science company that designs, manufactures, and distributes high-performance compound and single-element semiconductor substrates, including indium phosphide, gallium arsenide, and germanium wafers, serving applications such as data-center connectivity, AI infrastructure, and fiber optics.

The move follows recent multi-year supply agreements, including an approximately $22.3 million prepayment from Coherent (NYSE:COHR) and an approximately $43.5 million capacity deposit from Lumentum (NASDAQ:LITE), alongside a sharp second-quarter 2026 turnaround in which revenue jumped to $47.6 million from $26.9 million sequentially as the company swung to profitability on record indium phosphide revenue.

Stock Has Vastly Outpaced the Sector

AXT shares have climbed nearly 1,470% over the past year, compared with the semiconductor sector's roughly 22% gain over the same period, even as the broader Philadelphia Semiconductor index tumbled roughly 5% this week amid AI-slowdown fears and a Federal Reserve rate hike added to market volatility.

Valuation and Analyst Views Diverge

The stock now trades at a forward price-to-earnings ratio of 40.80, among the richer valuations in the semiconductor sector, and carries an elevated rating from a widely used research-ranking service, even as some market commentary remains split on the name given its exposure to Manufacturing operations in China.

Outlook: Company-Specific Momentum Faces a Valuation Test

The continued buying suggests investors see the recent supply deals and profitability turnaround as durable rather than one-off, with the rally driven primarily by company-specific catalysts rather than broader sector strength. Sustained indium phosphide Demand and further customer agreements will likely determine whether the stock can hold its premium valuation.
