Investment Thesis
Classic trough-to-recovery: Hipore separator EBITDA remains depressed but North America supply chain building. FY2026 record OP ¥231.2B driven by Healthcare (pharma+Zoll) + Homes — separator weakness masked by diversification. Charlotte NC coating starts supply to Toyota Tsusho mid-2027 (confirmed). Port Colborne Ontario ($1.56B plant) proceeding to H1 2029 production (delayed). Valuation at trough: PE 13.4x, PB 1.07x.
Risk
Hipore recovery timeline extended — Port Colborne delayed to 2029 (Honda Canada suspended EV plans but maintained 25% stake). Chinese separator competition intensifying. Materials segment OP declined in FY2026 despite record group profit. EV demand timing uncertainty. FY2026 record OP at group level creates AP01 optic risk (though underlying separator is still at trough — not true AP01).
Monitoring Trigger
Charlotte NC coating facility commercial production (H1 FY2027 = Apr-Sep 2026 — check Q1 FY2027 commentary). Toyota Tsusho supply start mid-2027 confirmed. Port Colborne groundbreaking/construction progress. Hipore segment EBITDA recovery signal. If Materials segment OP turns positive on separator, UPGRADE. If Port Colborne is cancelled, DOWNGRADE.
