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

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 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 

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 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 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 a mispriced European AI photonics play: it holds over 90% of the market for the MOCVD reactors that grow the indium phosphide crystals used in AI data center lasers, so every laser in Nvidia or Broadcom optical transceivers starts in its machines. Customers include Coherent, Lumentum, Nokia/Infinera and SMART Photonics, and laser lead times stretch past 2027. Despite a significant re-rating, it trades at 38x EV/EBITDA versus 84x for peers like BESI. x.com 

AXT's permit-backed Q4 outlook weakens the near-term operating objection to the Sell case. Q3 revenue reached $73.4M at 56% GAAP gross margin; management guides to about $90M in Q4 from business permitted or not needing permits. InP contributed $54.3M and backlog exceeds $500M, though much spans years. The remaining test is whether 2027 capacity becomes qualified, permitted shipments at durable margins. x.com  x.com  x.com 

X-FAB's earnings confirmed direct exposure to co-packaged optics and the 800V shift, which should drive a re-rating as markets price growth ahead. Management said it is progressing in CPO, with three silicon photonics projects and photonics volume production expected in 2028, a timeline not in revenue models yet. The 800V transition supports SiC and GaN demand, with three new SiC data center design wins pointing to a 2027 ramp. Current revenue is unimpressive, so some waiting is needed. x.com  … Show more
