Investment Thesis
Q Glass (quartz, Df 0.0005) meets M9 CCL spec for Nvidia Rubin — but Asahi Kasei is ONE OF SEVERAL Q glass suppliers, not a monopolist. Competitors: Glotech (Taiwan, 5475.TWO) makes higher-purity quartz yarn (99.995%), Feilihua (China, 300395.SZ) has full vertical chain with Nvidia cert and volume production. Still worth owning at PE 13.4x with 3.5% yield — priced for zero Q glass premium. Target 3x glass cloth sales by 2030.
Risk
NOT a monopoly like Nittobo T-glass — multiple Q glass competitors globally. Feilihua (China) already has Nvidia certification and 50,000 m/month production. Glotech (Taiwan) may be upstream quartz yarn supplier. Conglomerate dilution persists.
Monitoring Trigger
Watch M9 CCL mass production ramp in H2 2026. If Q Glass adoption confirmed by major CCL makers (TUC, EMC), thesis materially strengthens. Track segment profit disclosure for glass materials.
