The letter of intent is the document that most sellers treat as a cause for celebration. The offer has been evaluated, the preferred buyer has been selected, and both parties have agreed on the essential terms. The deal feels done. And in that moment of relief, sellers often do the one thing that will cost them the most money in the entire transaction: they sign the LOI without reading it carefully enough, without understanding the specific provisions that will govern the next sixty to ninety days, and without appreciating that several of those provisions are designed to shift economic risk from the buyer to the seller.

The LOI is non-binding on price and most material terms — but it is binding on the two things that matter most in the period between signing and closing: the exclusivity obligation, which prevents the seller from talking to other buyers, and the conduct of business covenant, which governs how the seller can operate the company during diligence. Everything that happens after the LOI — due diligence, purchase agreement negotiation, closing adjustments — occurs in the shadow of these provisions.

The LOI sits at the midpoint of a sale process that has significant consequences at every stage. If you are still early in your thinking about a transaction, our guide to the seven phases of a successful business sale maps the full journey from initial discovery through closing — including where the LOI fits, what it commits you to, and what leverage you have before and after you sign. Understanding that context makes every clause below considerably easier to evaluate.

Gotcha #1: Broad and Lengthy Exclusivity Periods

The exclusivity clause in an LOI grants the buyer a defined period — typically 45–90 days, though buyers frequently push for 90–120 — during which the seller cannot solicit, encourage, or engage with other potential acquirers. During this period, the competitive tension that drove the buyer to their initial offer price evaporates. The buyer knows they have exclusive access to the deal; there is no risk of a competing party submitting a better offer. That shift in negotiating dynamics is precisely what makes exclusivity valuable to buyers and costly to sellers.

The gotcha here is not that exclusivity exists — some exclusivity is reasonable and necessary for a buyer to invest in diligence — but that sellers often agree to exclusivity periods that are longer than necessary, with insufficient protections against buyer delays that extend the effective exclusivity period beyond its stated duration. A buyer who commits to a 60-day diligence process but raises new issues in week seven, requests document extensions in week nine, and delivers a redlined purchase agreement in week eleven has effectively extended exclusivity well beyond 60 days without the seller's explicit consent.

"The moment you grant exclusivity, the competitive tension that produced your offer price disappears. Every week of unnecessary exclusivity is a week in which the buyer can renegotiate with no consequence."

Negotiate the exclusivity period carefully: A reasonable LOI exclusivity period in the lower middle market is 45–60 days for a well-prepared seller with organized documentation. Buyers who request 90 days should be asked to explain specifically why their diligence requires that timeline. Sellers should also negotiate a provision that automatically terminates exclusivity if the buyer has not delivered a substantially complete draft purchase agreement by a defined date — converting the exclusivity period from an indefinite obligation into a time-bounded one with buyer accountability.

One underappreciated driver of unnecessarily long exclusivity periods is seller unpreparedness — when the data room is incomplete or financials are disorganized, buyers legitimately need more time. Sellers who have done the work described in our guide on how to prepare your financials for a business sale before going to market consistently experience shorter diligence timelines and stronger negotiating positions on exclusivity length.

Gotcha #2: The Working Capital Target and Adjustment Mechanism

The working capital provision in an LOI establishes the "target" net working capital that the seller is obligated to deliver at closing, with dollar-for-dollar purchase price adjustments for any shortfall or surplus relative to that target. This mechanism is legitimate and standard, but the specific target and methodology embedded in the LOI can significantly affect the seller's final proceeds — and buyers almost always propose these terms in a way that favors their position.

The most common working capital gotchas are: a target calculated as the trailing twelve-month average of monthly working capital, without seasonality adjustment, which can require the seller to deliver an above-normal working capital level if the measurement period includes peak months; a definitional scope that includes items the seller expected to exclude or excludes items the seller expected to include; and an accounting methodology provision that references GAAP without specifying which particular accounting elections will be used in the closing calculation, creating disputes later about which approach applies.

"Working capital disputes are among the most frequent and costly post-closing issues in lower middle market M&A. A disputed $300,000 working capital adjustment can cost both parties $150,000 or more in legal and accounting fees to resolve — on top of the economic impact of the adjustment itself."

Negotiating detailed, precise working capital definitions in the LOI — rather than leaving them to the purchase agreement — reduces the risk of these disputes substantially. Sellers who have analyzed their historical working capital patterns before going to market are far stronger negotiating positions on the target than those who have not. This analysis is part of the financial preparation process covered in detail in our guide on how to prepare your financials for a business sale. It is also worth noting that working capital is one of the five core drivers of what determines your business's valuation — getting it right before the LOI is signed has consequences that ripple through the entire transaction.

Gotcha #3: Broad "No-Shop" Language That Extends to Unsolicited Approaches

The no-shop clause prevents the seller from seeking alternative buyers during the exclusivity period — which is expected and reasonable. The gotcha version of this clause is the "no-talk" provision, which extends the prohibition to prevent the seller from even responding to unsolicited approaches from third parties. If a strategic acquirer approaches the seller independently during the exclusivity period with a superior offer, a broadly drafted no-talk clause can prevent the seller from even acknowledging the approach, let alone evaluating it.

Sellers should negotiate the no-shop clause to permit — but not require — responses to unsolicited approaches that are clearly superior to the terms of the signed LOI. This fiduciary out is standard in public company transactions and is increasingly accepted in sophisticated lower middle market deals. It does not require the seller to actively seek alternatives but preserves the right to respond if the market produces a genuinely better opportunity.

The distinction that matters: A no-shop clause stops you from shopping the deal. A no-talk clause stops you from listening. Sellers should accept the former and resist the latter — preserving the right to evaluate a materially superior unsolicited approach even during exclusivity, with appropriate notice to the current buyer.

The no-talk risk is especially significant for sellers who may have already received expressions of interest from other buyers before selecting their preferred party. Understanding which buyer types are most likely to make unsolicited approaches — and how to manage them strategically — is covered in our guide on finding the right buyer for your business, which includes a full discussion of strategic versus financial buyers and how competitive tension is maintained throughout a well-managed process.

Gotcha #4: Earnout Language That Transfers Future Risk to the Seller

When an LOI includes an earnout provision, the specific language used to describe the earnout metric, measurement period, and calculation methodology in the LOI will heavily influence — or in some cases determine — the final purchase agreement earnout terms. Buyers who are skilled at LOI drafting will include earnout language that appears seller-friendly on its face but that contains ambiguities or buyer-favorable defaults that become apparent only when the purchase agreement is drafted.

The most consequential earnout gotchas are: metrics defined as "EBITDA" without specifying which adjustments are included or excluded, leaving the buyer to argue for a more restrictive definition during purchase agreement negotiation; measurement periods that begin at closing rather than at the start of a fiscal year, creating partial-period complications; and missing provisions about what the buyer is required to do — or not do — to maintain the earnout's achievability post-close.

Earnout language in the LOI should be as specific as the earnout language in the purchase agreement — because it will largely become the purchase agreement language. Sellers who grant exclusivity based on vague earnout terms frequently discover that every ambiguity is resolved in the buyer's favor during the purchase agreement phase, when the seller has no competing leverage to push back. Our complete guide on what is an earnout in a business sale explains the full structure and risk profile of earnout provisions, including the specific protective language — operating covenants, expense allocation restrictions, independent measurement mechanisms, and acceleration on change of control — that sellers should insist upon before granting exclusivity.

It is also worth understanding how EBITDA itself is calculated before agreeing to any EBITDA-based earnout metric in the LOI. The same definitional nuances that affect your base purchase price will be fought over again at earnout measurement time. Our guide on what is EBITDA and how is it calculated covers every component of the calculation — and makes clear why a vague EBITDA reference in the LOI is a dispute waiting to happen.

Gotcha #5: The Material Adverse Change Termination Right

Most LOIs include a provision allowing the buyer to terminate the agreement if a material adverse change (MAC) occurs in the business between signing and closing. MAC provisions are legitimate — they protect buyers against genuine business deterioration that makes the acquisition thesis untenable. The gotcha version of a MAC clause is one defined so broadly that normal business fluctuations — a quarter of revenue below the prior year, the departure of a key employee, a customer who reduces order volume — could be argued to constitute a material adverse change.

Sellers should negotiate MAC definitions that exclude ordinary course business events, require a threshold of business impact before the clause can be triggered, and specify that the change must be both material and adverse to the business's long-term prospects — not just a transient fluctuation. A well-negotiated MAC clause protects the buyer against genuine catastrophe while giving the seller protection against tactical use of the clause to renegotiate terms or create leverage for price reductions that would not otherwise be justified.

Why MAC clauses get weaponized: A buyer who has developed cold feet — for market reasons, financing reasons, or simply a change of conviction — may look for a MAC argument as a way to exit or force a price reduction without admitting the true reason. The more precisely the MAC is defined in the LOI, the harder it is to invoke opportunistically. Specificity is the seller's best protection.

MAC clause exposure is amplified for sellers whose businesses have concentrated revenue — a single large customer who reduces orders could trigger a MAC argument if the clause is broadly drafted. This is one of many reasons that customer concentration, owner dependence, and other structural risk factors identified in our post on the five most common deal-killers in a business sale are worth addressing before going to market — not just to improve valuation, but to reduce the surface area that a buyer can use against you in the LOI and purchase agreement.

The Bigger Picture: Why the LOI Is Where Many Deals Are Won or Lost

Each of the five gotcha clauses above shares a common characteristic: the damage they cause is almost entirely preventable if the seller has experienced representation during the LOI negotiation. Sellers who sign LOIs without advisors — or whose advisors are insufficiently familiar with lower middle market deal dynamics — frequently discover in the purchase agreement phase that they have already conceded the most important economic terms without realizing it.

The LOI phase feels like the end of the negotiation because the headline price has been agreed. In reality, it is the beginning of the phase where value is most commonly eroded. Exclusivity has been granted. Competing buyers have been turned away. The seller's leverage has peaked and will not return unless the buyer demonstrates bad faith severe enough to justify terminating the LOI — a high and costly threshold.

There is also a timing dimension that sellers often underestimate. The longer you wait to engage advisors and begin preparation, the less leverage you have at every stage — including the LOI. Sellers who enter the market without a clear picture of their normalized EBITDA, their working capital baseline, and their deal structure priorities — including the asset sale vs. stock sale decision, which alone can determine how much of the headline price the seller actually keeps — are negotiating blind at precisely the moment when clarity is most valuable. Our guide on asset sale vs. stock sale tax implications explains why this decision belongs in the pre-LOI conversation, not the post-exclusivity one.

If you are in the early stages of considering a sale, our post on the cost of waiting to sell your business makes the case for why preparation time — the period before you are under LOI pressure — is the most valuable time in the entire process. And our post on how to know when it's the right time to sell helps you evaluate whether you are approaching that window with the preparation it deserves.

Finally, understanding the quality of earnings process — which typically begins immediately after the LOI is signed — gives sellers important context for why LOI definitions matter so much. The working capital methodology and EBITDA definition agreed in the LOI become the measuring sticks against which the buyer's QoE firm evaluates the business. Our guide on the quality of earnings report and why every seller should prepare for one explains how that process works and how proactive preparation protects sellers from late-stage surprises that can unravel both price and structure.

Frequently Asked Questions

What is a letter of intent in a business sale and is it legally binding?

A letter of intent is a document in which a buyer expresses their intent to acquire a business on specified terms, subject to the completion of due diligence and the execution of a definitive purchase agreement. The LOI is generally non-binding on price and most material terms — neither party is legally required to complete the transaction. However, certain specific provisions — most importantly the exclusivity clause and the conduct of business covenant — are typically binding and enforceable. These binding provisions govern the most consequential period of the transaction, between signing and closing.

What is an exclusivity period in an LOI and how long should it be?

An exclusivity period is the defined window after LOI signing during which the seller agrees not to solicit, encourage, or engage with other potential buyers. It allows the buyer to invest in due diligence with confidence that the opportunity will not be lost to a competitor. A reasonable exclusivity period in the lower middle market for a well-prepared seller is 45–60 days. Buyers who request 90–120 days should be asked to explain specifically why their diligence requires that timeline. Sellers should also negotiate a provision that automatically terminates exclusivity if the buyer fails to deliver a substantially complete purchase agreement by a defined date.

What is the working capital adjustment in an LOI and why does it matter?

The working capital adjustment provides that the purchase price will be adjusted, dollar for dollar, based on the difference between the actual net working capital delivered at closing and a target level established in the LOI. If the business delivers less working capital than the target, the seller receives less; if it delivers more, the seller receives more. The specific target and methodology can significantly affect the seller's actual proceeds, and buyers typically propose these terms in their favor. Sellers should negotiate working capital definitions carefully in the LOI. The financial preparation work that informs this analysis is covered in our post on how to prepare your financials for a business sale.

What is a no-shop clause and how is it different from a no-talk clause?

A no-shop clause prevents the seller from actively seeking alternative buyers during the exclusivity period — it prohibits solicitation of competing offers. A no-talk clause is more restrictive: it prevents the seller from even communicating with parties who approach them unsolicited during exclusivity. Sellers should negotiate for no-shop language rather than no-talk, and should preserve a fiduciary out that allows them to respond to unsolicited approaches that are clearly superior to the LOI terms without triggering a breach.

What should earnout language in an LOI include?

Earnout language in the LOI should specify: the precise performance metric being measured, with enough definition to minimize interpretation disputes; the measurement period and whether it aligns with fiscal years; the accounting methodology for calculating the metric; the specific buyer obligations regarding operation of the business during the earnout period; and the dispute resolution mechanism if the parties disagree on the earnout calculation. Vague earnout language in the LOI almost invariably benefits the buyer during purchase agreement negotiation. For a complete guide to earnout structure and risk, see our post on what is an earnout in a business sale.

What is a material adverse change clause and how should sellers negotiate it?

A material adverse change clause gives the buyer the right to terminate the transaction if the business experiences a significant negative change between LOI signing and closing. MAC clauses are standard and legitimate, but sellers should negotiate definitions that exclude ordinary course business fluctuations, require a threshold of impact before the clause is triggered, and focus on changes that are both material and adverse to the long-term business rather than transient operational variations. A well-negotiated MAC clause protects the buyer from genuine catastrophe without providing a pretext for tactical renegotiation.

Can LOI terms be renegotiated after signing?

Technically, any provision can be renegotiated at any time if both parties agree. As a practical matter, however, the seller's leverage to renegotiate declines sharply after the LOI is signed and exclusivity is granted. The competitive tension that drives favorable terms — the existence of other interested buyers — disappears the moment exclusivity is granted. Sellers who discover that LOI terms were unfavorable after signing face a difficult choice: accept the terms, attempt to renegotiate from a position of reduced leverage, or terminate exclusivity at significant cost with no certainty of a better outcome. The time to negotiate LOI terms is before signing, not after.

How does the LOI affect the quality of earnings process?

The LOI and the quality of earnings process are closely connected. The LOI's working capital definition will shape the working capital analysis in the QoE report. The earnout metric defined in the LOI will be the basis on which the QoE firm builds its financial model. And the exclusivity period granted in the LOI determines how much time the buyer has to complete their QoE review — which is why a well-defined, time-bounded exclusivity provision protects sellers from open-ended diligence. For a full explanation of the QoE process and how sellers can prepare proactively, see our guide on the quality of earnings report and why every seller should prepare for one.
