Most founders walk into the post-LOI repricing conversation cold. They have spent six months optimizing the marketing of the business and zero minutes preparing for the conversation that determines what actually closes. Then a buyer's diligence team surfaces a working capital gap or a customer concentration question, and the founder reacts in real time. The reaction is almost always wrong.
We tracked 89 lower-middle-market transactions in Q4 2025 and Q1 2026 (https://dx.doi.org/10.2139/ssrn.6515478). Post-LOI price adjustments occurred in 68 percent of deals. The median compression was 9.8 percent of the original LOI value. What separated the founders who held price from the founders who gave it back was rarely the underlying business. It was preparation for a specific conversation.
The conversation always follows the same arc. The buyer surfaces a gap. The founder explains it. The buyer reframes the gap as a risk. The founder either has a defensible response ready or improvises one. Improvisation costs money.
Here is what the conversation actually sounds like.
The buyer says some version of: "Our quality of earnings team flagged a $400K working capital adjustment based on our trailing twelve-month methodology. We need to adjust the purchase price accordingly." The unprepared founder pushes back on the methodology, argues the seasonality, and eventually concedes part of the gap. The prepared founder responds with their own twelve-month working capital analysis (already calculated, already documented) and either confirms the adjustment was anticipated or surfaces a methodology difference with specific monthly support.
The difference is not negotiation skill. The difference is preparation. The unprepared founder is doing the math live. The prepared founder did the math twelve months ago.
The same pattern repeats across the four most common repricing triggers. Owner add-back restatements. Customer concentration discounts. Revenue recognition timing differences. Working capital peg variances. In each case, the founder either brings their own analysis to the conversation or absorbs the buyer's analysis without a counter.
Three preparation moves change the conversation.
First, calculate every adjustment the buyer is likely to surface, using the exact methodology a PE quality of earnings team would use, twelve months before going to market. Document the calculation. Get a second opinion from someone who has run a sell-side quality of earnings before.
Second, draft your responses to each likely adjustment in writing. Not a script. A reasoned position with supporting data. Practice saying it out loud until you can deliver it without notes.
Third, rehearse the conversation with your advisor before the buyer is in the room. Most founders skip this step because it feels theatrical. It is not theatrical. It is the difference between holding price and giving it back.
The founders who close at LOI price are not better negotiators. They are better prepared. Preparation looks like detailed analysis done twelve months early and rehearsed conversations practiced before the buyer is in the room. The work is unglamorous. The return on the time is among the highest available in the entire transaction.
If you are twelve to eighteen months from a process and you have not yet drafted the repricing conversation, you have a preparation gap. The size of the gap will show up in the final purchase price.
