Behavioral M&A

Every step of this book has been building a case that a disciplined financial model is what separates a good acquisition from a costly mistake. But there is a harder truth underneath that: the model is only as disciplined as the person running it, and that person is rarely operating in a calm, objective state of mind.

Intellectually, everyone involved in a bid wants the model to be right. Nobody sets out to overpay. But a competitive auction does not reward calm, intellectual accuracy — it rewards whoever is willing to bid the most, and the pressure of the room pushes hard against objectivity. As the price climbs and a competitor's bid comes in higher than expected, the temptation is never to admit the deal no longer works at that price. The temptation is to find a way to make it work: stretch the headcount cuts a few points further than diligence actually supports, assume the revenue synergies arrive a year sooner, nudge the discount rate down or the terminal growth rate up until the number that was too high yesterday becomes comfortably affordable today. None of this feels like lying. It feels like optimism, like confidence, like finally believing in the deal the way the CEO believes in it.

Look back at Alpha's own numbers. The purchase price of 1.2x revenue was a real stretch above what Beta's earnings alone could justify — deliberately, since a bidder who only pays fair value for what a company already is has not really won anything, not against a determined rival. The 65% and 60% cuts assumed in Middle and Back Office, the 9% discount rate, the 2% terminal growth rate: every one of these is a judgment call, not a fact, and every one of them is exactly the kind of number that quietly drifts a few points in a bidder's favor when the room gets hot and a rival's bid just came in higher. Move any of them far enough and the deal that looked disciplined starts to look like a story someone wanted to be true.

This is why the finance officer who owns the model carries a duty that has nothing to do with winning the auction. Their job is not to make the numbers support whatever price the CEO wants to pay. Their job is to hold the model to what diligence has actually shown, to say plainly when an assumption has moved past what the evidence supports, and to let the deal team decide — with open eyes — whether they are willing to bid past that point anyway. A model that always finds a way to justify the winning bid is not a disciplined model. It is a rationalization with a spreadsheet attached.
