Investment Thesis
Sole Japanese NCA cathode source at scale, directly in Panasonic→Tesla chain. Panasonic-SMM nickel recycling JV (Mar 2025) deepens relationship — targeting 20% recycled content by 2027. Capacity tripling: 60K→180K tonnes/yr by 2031 ($424M invested). FY2026 NI forecast raised to ¥140B (consensus ¥88.6B) on copper/gold price tailwinds. US/Europe NCA demand intact as LFP remains China-centric (83% of LFP deployment in China 2025).
Risk
ANTI-PATTERN FLAGS: (AP01) FY NI near-record ¥140B driven by metals prices not structural NCA growth — peak earnings risk. (AP02) SMM expanding NCA capacity 3x by 2031 + Chinese HPAL expansion simultaneously — overcapacity risk 2028+. Nickel surplus 256K tonnes forecast 2026. LFP gaining global share (50% new EV capacity 2025). OP margin 5.0% = highly leveraged to commodity prices.
Monitoring Trigger
Watch: (1) LME nickel price vs $13,000/t floor — below triggers smelting segment losses. (2) Tesla Q-filing for cell chemistry mix — NCA vs LFP decision for US Gigafactories. (3) May 11 2026 full-year earnings: FY2027 guidance vs ¥140B NI level. (4) Chinese HPAL competitor capex announcements Q3 2026.
