Author argues the AI-disruption narrative is overblown for legacy software and that Constellation Software can buy mispriced verticals cheaply, generating an underappreciated free cash flow explosion.
CSU.TO — LONG The author argues that the narrative of AI replacing all SaaS and vertical software is wrong, based on his experience with legacy 80s/90s-era code that is deeply embedded, over a million lines, and cannot be replaced because no one understands it and downtime costs about $30k per hour. In his view this creates a stellar opportunity for Constellation Software to buy cheap, mispriced verticals due to the AI narrative, resulting in an explosion of free cash flow that no one is considering as a bull case. He recommends buying and holding for a few years.
In my view, and hopefully in management’s view at CSU.. This is a stellar opportunity to buy cheap, mispriced verticals due to the AI narrative. What we will end up with is an explosion of free cash flow that no one is even considering as a bull case right now.
