Nobody sets out to overpay for an M&A deal. Yet careful, experienced buyers do it constantly. 

Often, they treat this overpayment as a model failure, so they respond with more analysis. They look for better comps, tighter models, and sharper diligence. 

To their surprise, none of this works. That’s because overpayment was never an analytical problem. The main issues are deal fatigue and emotional momentum in M&A. 

It’s the fourteenth month with no results. The fourth Letter of Intent. The fourth deal that collapsed before signing. 

The model is sound. The person holding it is not. What corrects for that is an external circuit breaker, a framework that ensures deal detachment. 

The Trap of Deal Fatigue

Searching for a deal is a grind. Cold outreach seems to never work; owners take one call and never respond again, brokers favor other buyers, and months of work produce nothing. 

Somewhere along this timeline, a shift happens in the buyer. They stop evaluating businesses for what they are and start hunting for deals to end the search. 

Deal fatigue makes this feel rational. By then, costs are high. Legal fees, retainer payments, a paused career, and months of owning nothing weigh on the buyer. 

None of this should influence the next decision, but it always does. The buyer gets desperate. They stop looking for businesses that already work and look for businesses they could make work. 

It’s a subtle difference, but a difference that completely changes the buyer’s model. Worse, the buyer rarely notices that their way of thinking has changed. 

Emotional Momentum vs. Deal Detachment

Deal fatigue makes a buyer want any deal. Emotional momentum, on the other hand, is what a specific target does to a buyer already in that state. 

Momentum starts with the seller without them even meaning to start it. They always have a narrative. They’ve built something for thirty years, have a family name on the door, or have employees whose kids they watched grow up. 

A buyer who absorbs that narrative loses frame control. Not in a way of tone or posture, either. But in a way to detach themselves from the deal and to walk away. 

Deal detachment is that willingness. It’s the ability to leave the table at midnight, six months, and forty thousand dollars in, because a structural parameter shifted and the deal no longer clears the bar. 

A clearly defined acquisition thesis can help with detachment. It replaces emotions with parameters, helping buyers find the right business even when deal fatigue sets in. 

The Sins of the LOI Stage

Signing a Letter of Intent (LOI) means going exclusive. The seller stops running the process, and the buyer stops being one of many. 

It sounds like the buyer strength increases. However, that’s rarely the case. The buyer is all in, spending money on diligence, telling investors, etc. The seller has risked nothing. 

That’s why the Letter of Intent (LOI) discipline is not one stage of the process. It is the stage. 

Inflating the Post-Acquisition Growth Curve

Once the buyer decides they want the business, they become optimistic about growth projections. They look at untapped markets, pricing power the owner never used, and so forth. 

These projections, however, justify the multiple. It inflates it, and almost any price becomes defensible. Often, th

e buyer doesn’t even know that their instincts have stopped becoming reliable because of this optimistic approach. 

Ignoring Hidden Cap-Ex

Deferred maintenance looks identical to strong margins. An owner who stopped reinvesting three years before exit hands over an inflated EBITDA. 

The tells are fairly obvious, though. An aging equipment schedule and a cap-ex flat while revenue climbs are clear signs.

Despite this, the LOI is signed. The buyer is ready to take over the business, but they ignore the obvious. 

Talking Yourself Past the Obvious Risks

The customer who’s 40% of revenue, the relationship that leaves with the owner, and the multiple that gets nudged, the add-backs that get generous. These are all obvious risks. 

When a buyer is invested in a decision, they tend to overcome these risks with justifications. They’re done with the search and just want to get the deal done. 

Installing the Circuit Breaker

Discipline applied the moment pressure arrives is not discipline. It’s a coin flip. Structural downside protection needs to be installed beforehand, by someone who won’t be in the room when the pressure arrives. 

Pre-commit in writing. Before you see a single CIM, define your walk-away parameters, like maximum multiple, minimum margin, customer concentration ceiling, and cap-ex floor. 

Date it, sign it, and give it to someone else. Letter of Intent (LOI) discipline is nothing more than the willingness to honor a rule you wrote when you were clearly thinking. Then build a checklist that cannot be quietly overridden. 

The Value Is That They Do Not Care

An experienced M&A advisor carries no sunk cost from your search and no emotional exposure to your fatigue. Their detachment from the deal is a mechanism that makes a buy-side M&A strategy hold under pressure. 

They never meet the seller’s grandchildren. They have not spent fourteen months hunting. They don’t feel any relief if the deal is closed or not. This is exactly the type of person you need to close the deal with. It’s the circuit breaker that stops you from reacting emotionally. 

The Discipline You Cannot Supply Yourself 

The best buyers aren’t the ones with better instincts. They’re the ones who assumed their instincts would eventually fail and build something that holds when they do. 

Protection is not documented at the closing of a lower middle market acquisition. It’s a decision made before the search begins.
