The AI research card

Independent qualitative review of each pick before the order is placed. On the rare day the research service is unavailable, the paper book trades on the quant ranking alone and no card appears here.

Summary

AIXTRON SE designs and sells MOCVD/CVD epitaxial deposition systems for compound semiconductors, with optoelectronics (InP lasers for AI datacenters) now representing over 54% of equipment revenue and driving a sharp Q3 2026 order recovery to ~€275 million.

Rationale

The bottleneck-solver thesis is directly reinforced by AIXTRON's ~77% global MOCVD share, validated Lumentum G10-AsP qualifications, a backlog that nearly doubled to ~€457 million, and 42% forward revenue growth driven by a structural AI-optical interconnect ramp that competitors cannot immediately replicate.

Material risks

  • 1Lumentum or other laser OEMs qualifying Veeco systems or building in-house epitaxy capacity would directly dissolve the bottleneck moat that justifies the premium multiple and order momentum.
  • 2H1 2026 revenue was down 30% year-over-year at €174.5 million, meaning the bull case is entirely backlog/order-intake dependent — any demand normalization or export-control shock to China exposure would expose significant earnings downside before the recovery fully materializes.
