The thesis — preview.
Japanese ABF substrate co-leader — the other half of the substrate duopoly that gates every AI accelerator package. The narrative is intact (capacity sold through, profit-surge commentary, electronics segment strong), but Q4 FY26 EPS missed consensus (-13.5%) and the stock is up +881% trailing year. Tier B not Tier A because at +881% TTM with an earnings miss in the last print, the margin of safety is gone — you wait for a real reset before sizing up. Ibiden is the Japanese half of the ABF substrate duopoly — the supplier that has historically held the highest-layer-count and highest-yield substrates at Ibiden's Ogaki facility. Ibiden's substrates carry the package for Intel server CPUs (legacy strength) and increasingly for NVIDIA Blackwell / Rubin GPUs and AWS Trainium 2 ASICs. Ibiden also makes ceramic honeycomb structures for automotive catalytic converters (legacy, cyclical, low-multiple) — that mix dilution is part of why the multiple has historically been compressed and why the rerating once the AI mix dominated was so violent.…
