The Inflection Point
AXT's second-quarter 2026 results were nothing short of transformational. “Revenue for the second quarter of 2026 is $47.6 million. This is the highest quarterly revenue in AXT history.” — Gary L. Fischer, Chief Financial Officer · 2026-07-30 The driver was indium phosphide substrates, which brought in $30.7 million—also a company record. Gross margin skyrocketed to 45% (non-GAAP), up from 29.9% just a quarter earlier. The company swung to a non-GAAP operating profit of $11.2 million from a loss. This is the "exciting inflection" CFO Gary Fischer referenced, and it's confirmed by the numbers: Total revenue jumped 77% sequentially to $47.6M, the highest in AXT's history. The scale of the opportunity is redefining the company. CEO Morris Young stated, “We are committed to doubling our indium phosphide capacity in 2026 and I am pleased to report that we are ahead of the schedule in that effort.” — Morris S. Young, Chief Executive Officer · 2026-07-30 In fact, they now expect indium phosphide revenue to more than triple by year-end. The company is in "hypergrowth" mode, and the momentum is visible in the keyword landscape: CapEx spend and phosphide substrate have become dominant themes in the earnings call vocabulary.The Demand Story: Long-Term Supply Agreements
The demand is not spotty; it's being locked in via multiyear contracts. AXT has signed long-term supply agreements with Casella, Coherent, and most recently Lumentum. These deals come with significant prepayments—$22.3 million from Casella and $25.4 million from Coherent alone. Backlog now exceeds $100 million. This is a dramatic shift from a year ago, when the company was still discussing the potential of such agreements. As Tim Bettles noted in the prior quarter, “we are talking to a number of customers right now on long-term supply agreements as we build our capacity out and try to understand where their demand is going.” — Tim Bettles, Vice President of Business · 2026-04-30 Now those conversations have turned into signed deals. The CEO emphasized the rarity of the position: “We are the strongest position to increase manufacturing capacity quickly and at a scale and quality needed to move the needle in our industry.” — Morris S. Young, Chief Executive Officer · 2026-07-30 With only a handful of qualified indium phosphide suppliers globally, AXT is riding a wave of AI-driven demand for higher-speed optical connectivity.The AI Data Center Wave and Global Confluence
This story is part of a larger technological shift. The AI data center buildout is driving unprecedented demand for optical interconnects, and indium phosphide is the critical material for the lasers and detectors used in 100G and 1.6T transceiver modules. The global market has recognized this: co packaged optics is one of the top price movers in the 360-day window, with tickers like AVGO, MRVL, and LITE leading the charge. AXT is a direct beneficiary of this trend. The company's own long-term supply momentum is off the charts, confirming that this is not a one-quarter wonder. These multiyear agreements provide visibility and de-risk the capacity expansion. The fact that customers are prepaying for wafers is a powerful signal—they are essentially funding AXT's growth.So we are just experiencing a lot of positive influences right now. To push this over 40%. And, stay at 45% for now. But put your seat belts on.
