Why Middle-Market Deals Fail After the Term Sheet

Why It Matters

Understanding post‑LOI pitfalls helps founders avoid costly delays and price erosion, while giving buyers confidence to fund and close deals swiftly.

Key Takeaways

• EBITDA assumptions often collapse under due diligence.
• Hidden contract or IP issues trigger deal renegotiations.
• Financing tightening adds unexpected risk for middle-market deals.
• Seller unpreparedness prolongs timeline and erodes trust.
• Early operational cleanup reduces post‑LOI failures.

Pulse Analysis

The term sheet is a provisional agreement that masks the rigorous scrutiny of due diligence. In middle‑market transactions, buyers apply institutional standards—GAAP‑level financials, clean IP portfolios, and assignable contracts—to validate the valuation. When the underlying data diverges from the optimistic picture painted in the LOI, the deal is either repriced or abandoned. This stress‑test is especially harsh for founder‑led firms that have operated informally, making the gap between expectation and reality a primary source of failure.

Five common post‑LOI breakdowns dominate the landscape. EBITDA analyses frequently unravel as owners’ compensation, one‑time expenses, and churn patterns are re‑examined, eroding the price foundation. Non‑financial surprises—such as missing contract assignment clauses, IP ownership disputes, or misclassified employees—introduce risk premiums that sophisticated buyers cannot ignore. Meanwhile, a tightening credit environment has made financing more fragile, turning previously viable deals into dead‑ends. Prolonged negotiations breed fatigue, prompting sellers to walk away, while first‑time founders often lack the advisory bandwidth to navigate these complexities.

Proactive preparation is the antidote. Companies should restate financials on a GAAP basis well before market outreach, secure assignable contracts, and lock down intellectual property. Building a robust deal team—including an M&A attorney, quality‑of‑earnings analyst, and sector‑savvy banker—ensures that hidden issues are identified early. By treating the business as if it were already on the market, founders reduce risk, preserve momentum, and position themselves as the most attractive horse at the deal show, ultimately commanding higher multiples and smoother closings.
