See It Work — Apply the synergy haircut before the board meeting | Book 11 · AI Agents for M&A

The synergy model is the financial engine of every acquisition thesis — it answers 'why is this worth more to us than its standalone value?' and justifies the premium. The problem isn't the math; it's the assumptions: revenue synergies are inherently optimistic (cross-selling always sounds great in a model). The agent applies a disciplined haircut to those assumptions up front.

An un-haircut synergy model is how acquirers overpay. The expensive moment is Year 1, when results prove the optimistic model was fiction — but by then you've paid the premium. Applying the haircut before the board meeting is what prevents it.

What this means for you

The agent haircuts the optimistic synergy assumptions before you commit to the premium. What this means for you: you stop overpaying on cross-sell fantasies — the realistic case is on the table before the board approves, instead of becoming an unpleasant surprise in Year 1.

The synergy model gets a disciplined haircut before it justifies a premium:
