The upside case is a transition from proof-of-science to proof-of-franchise.
CASGEVY already gives real commercial validation and the balance sheet buys time, so CRISPR does not need every program to work. It needs
CASGEVY to keep compounding and one owned branch, most likely cell therapy or cardiometabolic editing, to look commercially credible. That supports strong returns, but not a 10x-style outcome from today’s starting valuation.
