AXT (AXTI) Could Be 13% Undervalued As AI Demand Fuels Its Valuation

AXT (AXTI) has attracted fresh attention after recent share performance, with the stock up over the past month and past 3 months. This has prompted investors to reassess how its semiconductor substrate business is being valued.

Over the past year, AXT has moved from a niche semiconductor substrate player to a high momentum story. A 1 month share price return of 29.45% has fed into a year to date share price gain of 376.07%, and a 1 year total shareholder return of more than 14x has dramatically reshaped how the stock is being priced.

For a stock that has already delivered more than 14x over 12 months, the jump to US$79.79 forces a harder question. Is AXT now largely pricing in its semiconductor substrate story, or is the recent surge only the opening move that the current valuation still understates?

Most Popular Narrative: 13% Undervalued

AXT closed at $79.79, while the most followed narrative framework points to a fair value of $91.60. That gap hinges on how investors see future AI driven demand, export trends and margin recovery playing out over time.

Accelerating global demand for high-speed data center connectivity and AI infrastructure is driving increased adoption of indium phosphide substrates, where AXT is a top supplier with 40% share. As export permit headwinds ease, this pent-up demand is expected to produce sharp revenue growth and improved utilization of manufacturing capacity.

See why 42 investors see AXT as 13% undervalued.

Result: Fair Value of $91.60 (UNDERVALUED)

Still, AXT faces two clear pressure points. Heavy reliance on Chinese customers and ongoing export permit uncertainty could quickly challenge today’s AI-driven valuation narrative.

Another View On AXT’s Valuation

There is a sharp contrast once the focus shifts from narrative fair value to what the numbers imply at today’s price. AXT trades on a P/S ratio of 40.8x, compared with 7.3x for the US Semiconductor industry, 4.1x for peers, and a fair ratio estimate of 28x.

That gap points to a lot of optimism already in the share price. This raises a simple question for investors: Is the current AI excitement enough to support such a premium if expectations or sentiment cool from here?
