AXT, Inc. Q3 2026 Earnings Recap

AXT shares fell 9.6% after earnings; the transcript offers no explicit guidance or outlook to explain the reaction. The key uncertainty is whether the sharp Q3 growth is sustainable: revenue was concentrated in indium phosphide and driven largely by data-center demand, while management said that demand is outpacing supply.

Key Takeaways

• Revenue was $73.4 million, up 54% sequentially and 162% year over year; indium phosphide contributed $54.3 million.
• Non-GAAP gross margin rose to 56.1% from 45.0% in Q2, and non-GAAP net profit was $26.8 million, or $0.41 per diluted share.
• Cash, cash equivalents and investments increased to $825.9 million. A $43.5 million customer prepayment under a long-term Lumentum supply agreement is recorded as a liability and will convert to revenue as wafers ship.
• The top five customers accounted for about 35% of revenue, and one customer exceeded 10%, underscoring customer concentration.
• Tongmei agreed to a private equity financing of up to $545 million; AXT expects to retain about 73.4% ownership if the maximum amount is raised.
