price 9% below the AI fair value

The price needs 6.0% growth a year for ten years. The AI thinks 9.0% is achievable, at a 22.0% margin.

Constellation buys mission-critical software used by governments and factories that is expensive to replace. It earns strong cash margins with almost no capital spending and reinvests every dollar into more acquisitions. At today’s price the market is essentially assuming it can keep buying good businesses forever at reasonable prices; that is plausible but leaves little cushion if deals get expensive or organic growth stays near zero.
