The probe card and automated test equipment (ATE) complex sits at a non-negotiable chokepoint in the AI semiconductor supply chain: every advanced logic die, HBM stack, and high-power accelerator must pass through wafer-level and package-level test platforms before shipment. The structural shift to HBM4, 2nm logic, and chiplet architectures is dramatically increasing test complexity, test time per wafer, and probe card wear-out frequency, creating a multi-year demand supercycle for the ATE duopoly (Advantest, Teradyne) and the probe card specialists (FormFactor, Technoprobe). However, valuations across the group have reached extreme levels (trailing P/E >60x for most, forward P/E >45x), pricing in years of uninterrupted growth and leaving little room for execution missteps or cyclical normalization. The capital cycle appears to be entering a late-mid-cycle phase where revenue growth is still robust but forward indicators (backlog, customer concentration, guidance ramp assumptions) are flashing warning signs, suggesting that selectivity and risk management are paramount.

| Ekspozycja na AI | Direct and pervasive. AI-related revenue now accounts for the majority of demand at Teradyne (~70%), and HBM testing drives ~50% of FormFactor’s AI chip costs. Every incremental AI accelerator requires 2–12 test insertions, making test a gating factor for production. |
The structural AI/HBM tailwind remains intact, but the entire sector is trading at valuations that already discount a "blue sky" scenario. Recent stock declines of 7–12% in a week (AEHR, FORM, TER) despite positive earnings indicate that the market is beginning to price in slower growth or multiple compression. The collapse of Teradyne’s backlog (-88% YoY) and the extreme forward P/E of Advantest (136.5x) relative to its trailing 63.3x suggest that consensus earnings forecasts for 2026 may be overly optimistic.
