UniCredit's takeover offer for Commerzbank at 0.485 shares per CBK share is trading below market price, creating an asymmetric bullish setup where either the bid gets raised (heads I win) or CBK executes its standalone plan targeting 21% RoE by 2030 (tails I win). Key risks include deal failure, German regulatory rejection, and UniCredit's inability to exit its 40%+ position without market impact.
