Canadian Solar's US energy-storage business is rewriting its valuation, and the shares look cheap against the sum of its parts. e-STORAGE delivered a record 2.7GWh in Q3 2025 with $3.1B of backlog, lifting gross margin to 17.2%, and US cell, module and battery plants under CS PowerTech target FEOC tax-credit rules. Modules, storage and project development are worth about $2.5-4B versus a $1.2-1.3B market cap. The discount reflects about $6.65B of debt and FEOC uncertainty. x.com x.com
