Somewhere right now, a founder is celebrating a signed letter of intent.
The number looked right. The banker said it was market. Three buyers came in within range of each other. The process worked exactly the way it was supposed to work.
Sixty days later, that founder will sit across a conference table and watch the number change.
The business did not get worse. The market did not shift. What happened is simpler and harder to accept: the buyer's accountant looked at the same financials the founder had been running on for fifteen years and produced a completely different result. The buyer, whether PE firm, strategic acquirer, family office, or search fund, was running a model the founder had never seen.
This happens in 73% of lower-middle-market transactions. The average price reduction between signed LOI and close is 18% of stated enterprise value. On a $20 million transaction that is $3.6 million moving from one side of the table to the other during the sixty to ninety days between a handshake and a closing.
The gap has a name. We call it the Preparation Gap. Unlike most problems in a transaction, it is almost entirely preventable. But only if you know which buyer you are preparing for.
Five buyers. Five different businesses.
Most founders discover this too late: there is no single buyer's lens. Five distinct buyer types are active in the lower-middle-market, and each one underwrites your business against a completely different model.
The private equity add-on buyer, which comprised approximately 72% of all PE deal volume in 2025, relies on leverage to generate returns. Lenders limit debt availability when customer concentration exceeds 40% of revenue. So the PE buyer applies a mechanical discount of 0.8x to 1.2x EBITDA when concentration crosses that threshold. It is not a negotiating position. It is a formula.
A strategic acquirer buying your business for market share may look at that same 44% customer concentration and see something entirely different: a deep, defensible relationship with exactly the customer they want. The PE buyer's discount becomes the strategic buyer's premium.
A family office making its third acquisition applies institutional underwriting standards. One making its first may not run a formal Quality of Earnings analysis at all. A search fund using SBA financing has specific addback rules baked into the lending criteria that make certain expense structures non-starters, no matter how legitimate they are.
Same business. Five completely different analyses. Sometimes two or three turns of EBITDA separating the highest realistic outcome from the lowest.
The founders who close at their number did not get lucky. They knew which buyer was realistic before they started preparing. Every fix they made was the right fix for the right buyer. Everything they left alone was irrelevant to the person across the table.
That is the whole game.
What each buyer actually looks at
Understanding buyer type changes how you read the three adjustment categories that account for most post-LOI value erosion.
Quality of Earnings restatements appear in roughly 45% of transactions with an average impact of 8 to 12 percent of enterprise value. PE buyers and search fund buyers are the most aggressive here because their returns depend on leverage, and lenders scrutinize every addback. A related party lease above market rate. Legal fees labeled one-time that happened twice. A family member on payroll at a rate that would not survive an arm's-length negotiation. All of it gets stripped. Strategic acquirers tend to be more flexible because they are buying capability and market position, not just EBITDA. A founder whose most realistic buyer is strategic may find that a proactive QoE conversation twelve months out surfaces fewer issues than expected. A founder squarely in PE territory will find that same conversation is the most valuable advisory engagement they will ever have.
Customer concentration is where buyer type changes the math most dramatically. The 40% threshold that triggers a mechanical PE discount is irrelevant to a strategic acquirer who wants that customer. For a leveraged buyer it is a credit constraint. For a family office it is a portfolio consideration. Eighteen months of work diversifying a customer base protects significant value in a PE transaction and may be entirely unnecessary in a strategic one. Founders who prepare generically, fixing concentration because an advisor told them concentration matters, may spend eighteen months and significant operational energy solving a problem that does not exist for the buyer most likely to pay them the most.
Management dependency applies most universally across all buyer types. Every buyer discounts a business where the founder is the business. Key person risk shows up in every underwriting model regardless of who is writing the check. The specific mechanism varies. PE buyers often express it through earnout structures that keep the founder engaged post-close. Strategic acquirers may require employment agreements. But the discount is consistent and the remedy is the same: demonstrable management depth developed over twelve months before the process begins.
The upstream window, and why buyer selection comes first
The upstream window is the twelve to twenty-four months before a founder engages a transaction advisor. The founder still has full operational control, faces no transaction timeline pressure, and can make changes that will appear in the financial statements buyers will examine.
Most founders enter this window without knowing they are in it. By the time they engage a banker, the window has typically been open for two years and used for none of its intended purpose.
Even founders who understand the upstream window make the same mistake: they start preparing before they know which buyer is realistic.
Customer diversification takes eighteen months. If PE is not a realistic acquirer for your business, if your size or sector or growth profile points toward a strategic buyer, that work protects value that was never at risk. Management development takes twelve months of demonstrated independence. If your most likely buyer is a family office making its second acquisition, the key-person discount may not apply the way it would in a PE deal.
Preparation without buyer lens selection is preparation for the wrong test. The founders who close at their number did not just prepare. They prepared specifically, for the buyer type that was actually realistic, in the lanes that were actually available, addressing the gaps that actually mattered to the model on the other side of the table.
The buyers have always known which lens they were using.
Now you do too.
