Episode notes
Toilets Company Makes Precision Chip Ceramics
- Toto's advanced-ceramic division makes precision parts used in chip fabrication, not bathroom fixtures.
- These ceramics hold silicon wafers during etching/deposition and must resist extreme heat, contamination, and maintain exact tolerances.
Activist Investor Spotlighted Toto's AI Angle
- Palliser Capital took a stake and called Toto an overlooked AI memory beneficiary, pushing the narrative publicly.
- The activist urged clearer communication of the ceramics value and sharper capital allocation including deploying ~76 billion yen net cash.
Ceramics Account For A Large Share Of Toto Profits
- The ceramics business reportedly contributes about 40% of Toto's operating profit, revealing a major non-consumer segment.
- That segment supplies components for wafer fabs amid rising wafer utilization driven by AI memory demand.
