The Counter-Intuitive Advice
When selecting an M&A advisor, the instinct is to run a broad beauty contest — invite every banker any board member knows, let them pitch, compare proposals, then decide. Limiting the process to two or three banks sounds self-serving coming from a banker. But understanding the incentive structures at play reveals why large beauty contests can work against a seller's interests.
What Losing Bankers Do Next
Preparing a serious pitch is not a lightweight exercise. A banker competing properly invests real resources: market analysis to produce differentiated insight, competitive mapping to define a credible buyer universe, and positioning work to frame the company's strategic narrative. To do this effectively, they request data, hold Q&A sessions, gather metrics, test valuation expectations, and probe the conditions under which a buyer could realistically win the deal.
By the end of a beauty contest, each banker has effectively built a mental investment case. When a banker loses the mandate, they do not simply walk away and forget what they have learned. They have invested time, internal resources, and reputation. The most natural path is to reposition themselves on the buy-side, advising potential acquirers.
This is where information leakage begins. The losing banker approaches buyers with context: metrics, valuation expectations, pressure points, internal constraints. They understand what range was implicitly discussed and what would make the board comfortable. Their objective is to help a buyer win and demonstrate their own value in doing so.
The Cascade Effect
This dynamic does not happen once. It happens once per losing bank. The larger the beauty contest, the more parallel buy-side repositioning it creates.
In practice, this can neutralize the competitive tension that a sell-side process depends on. When multiple buyers are each advised by a former beauty contest participant, valuation expectations converge. What should have been competitive tension gradually turns into consensus. Buyers anchor around similar ranges, the narrative converges, and the dispersion that drives premium outcomes never fully emerges.
The Real Trade-Off
No one in this scenario behaves improperly. The management wants thoroughness, the board wants governance comfort, the banks want to justify their investment, and the buyers want informed advice. Yet the combined effect is the destruction of information asymmetry — and with it, the erosion of valuation dispersion.
Limiting the shortlist to two or three banks preserves competition where it actually matters: among buyers, not among advisors. The goal is to maintain the information advantage that drives premium outcomes in the process that counts — the sale itself.
