Letter of Intent in a Business Sale: What’s Binding, What’s Not, and What to Negotiate

Here is a thing that surprises a lot of sellers: the moment in a business sale where the most important decisions get made is not when you sign the purchase agreement. It is when you sign the Letter of Intent.

The LOI is a preliminary document, typically 5-10 pages, that establishes the key economic and structural terms of the transaction before lawyers write the definitive agreement. Most of it is non-binding. But several provisions, most importantly exclusivity, are very much binding, and they shape everything that follows.

Sellers who treat the LOI as a formality and sign it quickly to keep momentum going sometimes discover, 60 days later, that they are locked into a price that has been renegotiated down, with a buyer who knows they have no leverage to walk away.

A letter of intent in a business sale is a preliminary document that establishes the key deal terms before a definitive purchase agreement is negotiated. The LOI typically covers purchase price, deal structure, exclusivity period, key conditions, and timeline. Most of the LOI is non-binding, but exclusivity and confidentiality provisions are binding and materially affect the seller’s leverage throughout the process. Getting the LOI right is as important as getting the purchase agreement right, and most sellers spend less time on it.

Key Takeaways

• The LOI establishes the economic terms that will be difficult to reopen once the definitive agreement process begins. Negotiate it with the same rigor as the final document.
• Exclusivity provisions are binding, typically 60-90 days, and prevent the seller from marketing to other buyers while the primary buyer conducts due diligence.
• Confidentiality provisions in the LOI are binding and govern how the buyer handles information shared during due diligence.
• Purchase price, deal structure (cash vs earnout vs seller note), working capital peg, and exclusivity period are the four most important LOI negotiation points.
• One-third of signed LOIs do not result in closed deals, according to industry data, making the quality of the buyer selection before signing the LOI as important as the terms themselves.

What an LOI Typically Covers

The contents of an LOI vary, but a lower middle market business sale LOI typically includes:

Purchase price and deal structure. The headline price and how it is allocated, cash at close, seller note, earnout consideration, equity rollover. This is the core economic term and the foundation of every decision that follows.

Enterprise value vs equity value. The LOI typically states enterprise value (the total purchase price of the business). The equity value you actually receive depends on working capital adjustments, debt, and transaction expenses. Understanding this distinction before signing prevents unpleasant surprises at close.

Working capital target. The LOI usually establishes how working capital will be handled, either a specific target or a formula for calculating it. This provision generates more post-LOI disputes than almost any other.

Exclusivity. The provision that locks the seller into working with one buyer. Typically 60-90 days. The seller cannot market the business to other buyers during this period.

Due diligence conditions. What the buyer needs to verify before they are committed to close. This is where the buyer preserves their ability to renegotiate if due diligence surfaces issues.

Key representations. Preliminary statements from the seller about the business’s material financial condition, legal standing, and operational status.

Timeline to close. Expected timeframe from LOI signing to closing.

Confidentiality. Binding, governs how the buyer handles information about the business.

What Is and Is Not Binding

The non-binding provisions of an LOI include the purchase price, deal structure, and most of the commercial terms. This non-binding nature protects both parties, it allows negotiations to proceed without either side being legally committed before full due diligence is complete.

But the LOI creates real obligations in two areas:

Exclusivity is binding. When the seller signs an LOI with an exclusivity provision, they are legally prohibited from marketing the business to other buyers for the exclusivity period, typically 60-90 days. This is a meaningful constraint. If the buyer uses the exclusivity period to conduct due diligence and then tries to renegotiate the price downward, the seller’s options are: accept the revised terms, restart the entire sale process from scratch after the exclusivity period expires, or walk away and lose the momentum, time, and transaction costs invested.

Confidentiality is binding. The buyer’s obligation to protect the seller’s confidential information, maintain the confidentiality of employees and customers who are not yet aware of the transaction, and use information provided only for purposes of evaluating the acquisition, these are binding.

Understanding this creates the right negotiating mindset. Non-binding does not mean the LOI terms do not matter. It means they can be adjusted in the definitive agreement if both parties agree. In practice, major deviations from LOI terms require significant justification, and the buyer has leverage if due diligence surfaces unexpected issues.

The Four Highest-Impact LOI Negotiation Points

1. Purchase price and structure. Price and structure in the LOI establish the anchor for every subsequent conversation. If the LOI says $10M with $8M cash and $2M earnout, the definitive agreement will be built around that framework. Getting the structure right now, understanding what the earnout terms mean, what the seller note carries, what earnout protections you need, is essential before you sign.

2. Exclusivity period and length. Negotiate the exclusivity period as short as possible while giving the buyer enough time to conduct meaningful due diligence. 60 days is reasonable for a well-prepared business with clean financials. 90 days is standard for more complex transactions. Pushing beyond 90 days without strong justification extends your exposure without proportional benefit.

Some sellers also negotiate conditions under which exclusivity terminates early, for example, if the buyer fails to conduct due diligence in good faith or proposes to renegotiate material terms without new information. These provisions rarely need to be invoked but significantly improve the seller’s position if the process goes sideways.

3. Working capital target. How the LOI frames working capital has significant financial consequences at close. If the LOI establishes a specific working capital target, make sure it reflects the actual historical average of the business, not a number the buyer proposes that is higher than your typical level.

4. Due diligence conditions. The fewer open-ended conditions the better for the seller. Buyers sometimes include provisions that give them significant discretion to renegotiate if “due diligence reveals material issues”, without defining what constitutes a material issue. Push for specific, defined conditions rather than open-ended language that creates uncertainty about when the deal is truly committed.

The One-Third Rule and Buyer Quality

One-third of signed LOIs in the lower middle market do not result in closed deals. This number matters because it means the buyer you are signing the LOI with is not necessarily the buyer you will close with, and an exclusivity period with the wrong buyer is 60-90 days of market time you will not get back.

Before you sign the LOI, invest time in understanding the buyer’s seriousness, financing capability, and track record. A PE firm that has closed 15 lower middle market acquisitions in the last five years is a very different counterpart than an independent sponsor conducting their first transaction. A strategic buyer who has acquired three businesses in the past decade is different from one pursuing their first acquisition.

The quality of the buyer you choose determines the probability that the LOI leads to a closed deal.

Frequently Asked Questions

Is a letter of intent binding in a business sale?

Most of the LOI is non-binding, purchase price, deal structure, and commercial terms can be adjusted in the definitive agreement. However, two provisions are typically binding: the exclusivity period (preventing the seller from marketing to other buyers) and confidentiality obligations.

How long is the exclusivity period in a letter of intent?

Typically 60-90 days. Well-prepared businesses with clean financials can negotiate toward 60 days. Complex transactions or buyers who require more due diligence typically need 90 days. Exclusivity beyond 90 days should be justified by specific circumstances.

Can I negotiate price after signing the LOI?

The LOI price is non-binding, which means both parties can negotiate changes in the definitive agreement. In practice, buyers use due diligence findings to justify price reductions. A thorough, accurate LOI price that reflects well-documented financials, supported by a sell-side Quality of Earnings report, reduces the buyer’s ability to renegotiate after signing.

What happens if a buyer wants to renegotiate after the LOI?

If the buyer surfaces new information during due diligence that legitimately justifies a price adjustment, this is standard. If the buyer attempts to renegotiate without new information, essentially using exclusivity leverage to push for better terms, the seller can accept the revision, push back, or walk away. Having multiple buyers in the process before the LOI is signed gives sellers the most leverage in this situation.

What is a no-shop provision in a letter of intent?

A no-shop provision is another term for exclusivity, the seller agrees not to solicit or entertain competing offers during the exclusivity period. It is standard in LOIs and will typically be binding.
