When M&A agents fail — one missed footnote, $50M
These are illustrative-but-authentic failure patterns from agent-assisted M&A. One missed footnote cost $50M. One double-counted synergy destroyed board confidence. The common thread isn't that the agents were weak — it's that agent confidence without scope discipline is more dangerous than no agent, because a confident wrong answer gets trusted.
The full detailed chart. Condensed for print legibility in the book; shown here at full size.
The danger in agent-assisted deals isn't the agent being uncertain — it's the agent being confidently wrong outside what it's qualified to judge. Scope discipline — keeping each agent inside its lane — is what prevents the expensive miss.
