AIXTRON reaching meme status is just a matter of time, because over 90% share in indium phosphide equipment, per @jasonschips, combined with pricing power across both optics and power semiconductors exists nowhere else. x.com 

Aixtron's faster reactor shipments should lift Nynomic's LayTec revenue in H2 2026, not just 2027. Aixtron's Q3 revenue rose 54%, with Q4 guided higher; LayTec metrology is standard on its optoelectronics and power tools. The slower switch to 6-inch InP wafers means more reactors per chip volume. Aixtron expects the early-stage demand cycle to last until 2030. Framework-agreement call-offs leave much of this demand out of Nynomic's backlog; its estimated 2026 EV/sales is about 1.44x. x.com 

Aixtron is not a buy at the current price because the stock is expensive. x.com 

Aixtron is a decent proxy play on photonics because it basically has a monopoly on its indium phosphide equipment, while the photonics names are capacity constrained and InP remains an ongoing bottleneck. x.com 

InP substrate demand and pricing still support the AI optics supply chain. Yunnan Germanium reports higher InP volumes from AI data centers and optical communications, plus higher prices. Q3 revenue rose 134.6% year on year, near AXT's guided 136%, but also includes germanium. IQE's H1 photonics grew 45%, partly from US defense funding. AXT's $66m Q3 guide covers only licensed exports or sales needing no license; a miss would more likely reflect licensing. x.com 

Aixtron and Veeco will probably never see their old highs again, because semiconductor equipment makers look stretched above about 11x price-to-sales. Fifteen years of software multiple expansion have conditioned investors to accept high multiples, but equipment makers have very different margin structures. The broader bull market is still far from over even though fundamentals look overheated, with momentum doing the heavy lifting. x.com 

Aixtron's indium phosphide business is grossly under-modeled, as MOCVD machines may become the gating factor for scaling co-packaged optics. It holds 90%+ share in InP, a rare monopoly in optics and power chips. GaN and SiC markets will reach tens of billions and capacity will run out once new data centers adopt 800V DC, so even a fraction of that in MOCVD demand means billions of revenue for a $6 billion company. CPO and 800V DC each have three ramp phases, each half an order larger. x.com 

Aixtron and Veeco stand to benefit because indium phosphide is the real bottleneck in optical interconnect, one nothing else can replace. InP looks set to stay structurally short in both demand and supply over the next three to five years, a theme the market has not yet fully priced, which makes both equipment makers attractive. x.com  x.com 

Aixtron's position is durable but not unconstrained, with optical lasers carrying the near-term case: it holds over 90% of InP MOCVD and every high-speed laser traces back to its reactors. Its share will likely erode toward 65-75% by decade-end as Veeco improves and Chinese buyers diversify, manageable if the InP tool market doubles or triples. The bigger near-term limit is capacity, as Aixtron reallocates existing lines rather than adding aggressively. 800V DC power demand looks further off. … Show more

AXT's indium phosphide substrate chokepoint gives it pricing potential, though its Coherent agreement caps annual wafer-price increases. Channel checks suggest increases of 50-60% in Q2 2026, 10% in Q3 and over 10% in Q4. With supply agreements to Lumentum and Coherent, AXT probably becomes No. 1 ahead of Sumitomo Electric. A SanDisk-style hike now looks less likely because of the annual cap, whose percentage is redacted. x.com
