The Letter of Intent is the moment a business sale conversation becomes a business sale process. Before the LOI, you have relationship, interest, and preliminary financials. After the LOI, you have a framework — a defined price, a structure, and a timeline that gives both parties the confidence to invest seriously in closing the transaction. Writing an LOI that gets accepted by a motivated seller requires understanding what sellers actually care about, what language creates confidence rather than friction, and where to be specific versus where to leave room for the inevitable negotiation that follows due diligence. Get this document right and you accelerate toward closing. Get it wrong and you lose deals that should have been yours.

According to M&A advisory professionals across the lower middle market, the LOI phase is where more deals stall or fall apart than any other single stage. Price misalignment is the obvious reason — but subtler issues, including overly aggressive conditionality, ambiguous structure terms, or unrealistic exclusivity and due diligence timelines, account for a substantial share of LOI rejections and renegotiations. A well-crafted LOI is not just a term sheet; it is a relationship signal from the buyer to the seller, communicating that they are professional, reasonable, and genuinely committed to closing.

What an LOI Must Cover

A proper LOI is concise but comprehensive. It should cover the key economic and structural terms of the proposed transaction clearly enough that both parties have a shared understanding of the deal they are agreeing to pursue through due diligence. It should not attempt to be the definitive agreement — that is what the Purchase and Sale Agreement is for — but it should be specific enough that there are no material misunderstandings about the fundamental nature of the deal.

• ✅ Purchase price: Total consideration, clearly stated
• ✅ Payment structure: Cash at closing, seller note amount and terms, earnout structure if applicable, equity rollover if applicable
• ✅ Transaction type: Asset purchase vs. stock purchase (has significant tax implications for both parties)
• ✅ Exclusivity period: Duration during which the seller agrees to stop all other sale discussions
• ✅ Due diligence period: Expected timeline for buyer's investigation
• ✅ Conditions to closing: Key conditions (financing, regulatory approval, key employee retention) that must be satisfied
• ✅ Working capital: Whether a working capital target/peg will be part of the agreement
• ✅ Non-compete: Proposed duration and scope of seller non-compete and non-solicitation
• ✅ Transition: Expected post-closing involvement of the seller

Pricing the LOI: Hitting the Range That Gets Accepted

The most critical element of any LOI is the purchase price — and the most common LOI mistake is offering a price that is either so far below the seller's expectation that it creates immediate friction, or so imprecise (wide price ranges, extensive conditionality) that the seller has no confidence a deal will actually get done. The goal is to offer a price that is credible, defensible, and clearly tied to the financial profile of the business as you understand it.

In the lower middle market, purchase prices are typically expressed as a multiple of normalized EBITDA. If you have done your preliminary financial analysis carefully and arrived at a defensible EBITDA figure, you can anchor your offer to that figure with a stated multiple. This approach gives the seller a framework for understanding your logic, which is important — sellers who understand how a buyer arrived at a price are far more likely to engage constructively with it than those who receive a number without context.

Research from deal advisory sources suggests that the initial LOI price is almost never the final price. Both parties expect some negotiation, both during LOI acceptance and again after due diligence. The buyer's goal is to open at a price that is serious enough to win exclusivity without giving away all their negotiating room. A price that is more than 10–15% below the seller's stated expectations typically results in an immediate rejection; a price that fully meets the seller's expectations with no due diligence contingency may leave the buyer exposed to post-diligence findings they cannot price in.

The Exclusivity Clause: Your Most Important Non-Financial Term

The exclusivity clause is the only binding provision in most LOIs, and it is the provision that matters most to the buyer. Exclusivity gives the buyer a defined period — typically 45–90 days — during which the seller cannot solicit or entertain other offers. This gives the buyer the confidence to invest in due diligence, legal review, and financing without the risk that the seller is simultaneously entertaining competing buyers.

Sellers often push back on exclusivity, particularly if they have not been through a sale process before and do not fully appreciate the buyer's perspective. The most effective way to secure exclusivity from a motivated seller is to be clear about why you need it (the cost and commitment of due diligence requires certainty that the deal can close) and to ensure that the exclusivity period you are requesting is realistic for your expected due diligence timeline. An exclusivity period that runs out before diligence is complete forces an extension request — a minor disruption to the process but one that erodes seller confidence.

✍️ Language That Builds Confidence vs. Language That Creates Friction

The tone and language of an LOI communicate as much as the economic terms. An LOI laden with extensive conditions, qualifications, and buyer outs signals to the seller that the buyer is not fully committed and is looking for easy exits. Conditions to closing should be limited to material, genuinely uncertain events: financing, regulatory approval where required, and extraordinary diligence findings. Every additional condition gives the seller (and their advisor) a reason to question the buyer's seriousness.

Conversely, an LOI that is clear, professional, and reasonably concise signals that the buyer is experienced, organized, and capable of executing. Many sellers — particularly those going through a sale for the first time — evaluate the buyer as much on how they behave during the LOI process as on the economic terms. A buyer who delivers a clean, well-organized LOI promptly, communicates clearly about their process and timeline, and responds to the seller's questions with patience and transparency is demonstrating exactly the qualities sellers want in an acquirer.

In off-market deals, where the relationship has been built over time and the seller has already decided they trust the buyer enough to have this conversation, the LOI is as much a formalization of the relationship as it is a commercial negotiation. Honor that relationship in how you write and present the document.

⚠️ Common LOI Mistakes That Derail Deals

• ❌ Wide price ranges: "We would pay $3M–$5M depending on diligence" tells the seller nothing and signals uncertainty
• ❌ Excessive conditionality: Long lists of conditions give sellers (and their advisors) reasons to decline
• ❌ Unrealistic timelines: Promising to close in 30 days when the actual process will take 90 creates early distrust
• ❌ Ambiguous earnout terms: Earnout metrics and calculation methodology must be clearly defined in the LOI, not deferred to the PSA
• ❌ Missing the seller's priorities: A seller who cares deeply about employee retention needs to see that addressed in the LOI — economic terms alone will not win the deal
• ❌ Delay in delivery: In off-market deals especially, a prolonged gap between verbal agreement on terms and LOI delivery erodes seller confidence and creates room for second thoughts

❓ Frequently Asked Questions

Is an LOI legally binding?

Most LOIs are non-binding on the economic terms — meaning either party can walk away if due diligence produces material findings or if the parties cannot agree on definitive agreement terms. The principal exception is the exclusivity clause, which is typically binding. Some LOIs also include binding confidentiality provisions. Buyers and sellers should work with their respective attorneys to understand exactly which provisions of their specific LOI are binding.

How long should the exclusivity period be?

The exclusivity period should be long enough for the buyer to complete due diligence and negotiate a definitive agreement, but not so long that the seller feels trapped. 60 days is a common starting point in the lower middle market, with 30-day extension options negotiated into the LOI or exercised by mutual agreement. Sellers with advisors will typically push for shorter exclusivity periods; buyers should negotiate for enough time to do the process correctly.

Should I use a standard LOI template or have an attorney draft it?

Experienced buyers who have completed multiple acquisitions often use modified template LOIs as a starting point. First-time buyers should have an M&A attorney draft or at least review the LOI before submission. M&A attorneys understand the specific representations and warranties that flow from LOI terms and can flag language that creates unintended obligations or that is inconsistent with market practice. The cost of attorney review is modest relative to the stakes of getting the terms wrong.

Final Thoughts

The LOI is where a buyer's preparation, judgment, and communication skills combine to either accelerate a deal or stall it. A well-crafted LOI — one that is specific, credible, reasonably conditioned, and presented with professionalism — builds seller confidence and creates the momentum needed to carry the transaction through the inevitable complexity of due diligence and definitive agreement negotiation. Take the time to get it right. The investment pays significant dividends in the quality and speed of everything that follows.
