The letter of intent is often treated as a formality, a handshake on price before the real work begins. In practice it is the point in a sell-side transaction where a business owner holds the most negotiating power, and that power tends to fall sharply once the document is signed. The reason is structural. An LOI in a lower-middle-market deal is mostly non-binding on price and terms, but the exclusivity provision it contains is usually binding, and exclusivity removes competing buyers from the picture during the exact window when the details get drafted. Terms left vague in the LOI are generally settled later in the definitive purchase agreement, where the buyer's counsel controls the first draft and the seller has fewer alternatives.
Why leverage peaks before exclusivity
Before an LOI is signed, a seller who ran a competitive process may have more than one interested party and a credible ability to walk to another table. That optionality is the source of leverage. Advisory commentary consistently frames the moment of signing as the high-water mark for seller negotiating power, because most terms only get worse for the seller from there, not better. Several dynamics drive the shift:
- Competing bids evaporate. Once exclusivity is granted, other interested buyers typically move on rather than wait, so the seller loses the ability to play offers against one another.
- Sunk costs accumulate. Legal, accounting, and advisory fees mount during diligence, creating pressure to close on whatever terms emerge rather than start over.
- Undefined terms default to the buyer. Anything not pinned down in the LOI is drafted by the buyer's lawyers first, and the starting point tends to favor them.
- Re-trading risk rises. With no alternative buyer waiting, a purchaser can attempt to renegotiate price or terms downward late in diligence, a practice commonly called a re-trade.
Binding versus non-binding provisions
A defining feature of the LOI is that it is a hybrid document. Roughly 85 percent of a typical LOI is non-binding, according to law-firm commentary, and the non-binding portion covers the commercial heart of the deal: purchase price, deal structure, working-capital treatment, escrow amounts, earnout mechanics, and the framing of representations and indemnification. These are described as expressions of current intent rather than enforceable obligations. A smaller set of provisions is usually drafted to be binding:
- Exclusivity or no-shop, which prevents the seller from soliciting or engaging other buyers for a defined period.
- Confidentiality, protecting information exchanged during diligence.
- Expense allocation, governing who bears which transaction costs.
- Governing law and dispute resolution, and sometimes access to information and conduct-of-business commitments during the exclusive period.
The distinction matters because courts have enforced entire LOIs as binding contracts when the language separating binding from non-binding terms was unclear. Clean drafting that labels each section is therefore a substantive protection, not boilerplate. The practical effect of the split is asymmetric. The seller gives a binding promise to stop shopping the business, while the buyer's commitments on price and structure remain aspirational and subject to change as diligence proceeds. Reading an LOI accurately means recognizing that the enforceable half largely constrains the seller, not the buyer.
Exclusivity length and structure
Exclusivity is the term that most directly converts seller leverage into buyer leverage, so its length and conditions carry real weight. Standard periods in middle-market private-company deals commonly run 30 to 90 days, with 45 to 60 days often cited as typical and some advisers favoring the shorter end. Buyers frequently push for longer windows or open-ended extensions. Beyond raw length, the way exclusivity is bounded can preserve some seller footing:
- Limiting automatic extensions to a single occurrence rather than an open renewal.
- Tying continued exclusivity to buyer milestones, so that a buyer who misses diligence or financing deadlines can lose it.
- Keeping the period long enough for genuine diligence but short enough to discourage a buyer from slow-walking the process.
A related consideration is what the seller may and may not do during the exclusive window. Some LOIs pair the no-shop with conduct-of-business commitments that limit how the company is run before closing, and with information-access rights that let the buyer into sensitive operational and financial detail. Those clauses are ordinary, but their breadth is negotiable while competing interest still exists, and less so afterward.
The terms that matter beyond price
Headline price is only one variable, and the structure around it determines how much cash a seller actually keeps and when. Several non-binding terms tend to move real value and are far easier to shape while competing interest still exists:
- Deal structure. Whether the transaction is an asset purchase, a stock or equity purchase, or a merger carries different tax and liability consequences for each side.
- Working-capital treatment. Most private deals close on a cash-free, debt-free basis with a normalized working-capital target. How that target is calculated, and whether a collar sets a no-adjustment band around it, is a frequent source of post-closing disputes when left undefined.
- Escrow or holdback. A portion of the price is commonly held back as security for representation breaches. Mid-market escrows have often run around 10 percent for roughly 12 to 18 months, though the growing use of representations-and-warranties insurance has pushed retained amounts lower in some deals.
- Earnout. Contingent consideration tied to future performance can bridge a valuation gap but shifts risk onto the seller. Objective metrics such as revenue are generally easier to measure than EBITDA-based targets, which invite disputes over post-closing accounting.
- Reps, warranties, and indemnification. LOIs often say only that these will be customary. Caps, baskets, survival periods, and which representations count as fundamental are usually settled later, and vague LOI language leaves that drafting to the buyer.
- Employment and rollover. Where an owner is expected to stay on or roll equity into the buyer's entity, the outline of those arrangements is easier to negotiate before exclusivity narrows the field.
How competition preserves leverage
The single largest lever a seller has is a credible alternative. A buyer negotiating against the knowledge that another party is waiting behaves differently from one who knows the seller is locked in. This is why the sequencing of a process matters: defining as many meaningful terms as possible in the LOI, while multiple parties remain interested, tends to lock in a stronger baseline than trying to improve terms after signing. Once a business is off the market under exclusivity, returning it to market mid-process can carry reputational cost and signal trouble, which further weakens the seller's hand. A structured, competitive process is what generates and sustains that optionality in the first place. The mechanics reinforce each other. Multiple credible bidders create pressure to define more terms up front, and a well-defined LOI in turn reduces the room a single buyer has to re-trade later. A seller who reaches the LOI stage with only one interested party has already spent much of the leverage the document is supposed to capture. Platforms such as Bankerly are built around running that kind of organized sell-side process so that owners reach the LOI stage with genuine alternatives rather than a single offer.
The LOI as an anchor
Even though most of the document is non-binding, its terms function as anchors for everything that follows. Once a price or a structure is written into an LOI, the definitive-agreement negotiation starts from that number rather than from a blank page. Concessions made early are difficult to claw back later, and terms left blank are filled in by the party drafting the contract. Treating the LOI as a preliminary sketch rather than a serious negotiation is one of the more consequential misreadings a seller can make, precisely because leverage is highest at that moment and declines thereafter. The anchoring effect also runs to structure and risk allocation, not price alone. An LOI that specifies a working-capital mechanism, an escrow size, and an earnout metric leaves less to be argued in the buyer's favor during purchase-agreement drafting. Comparing competing offers on a common basis, weighing guaranteed cash at closing against contingent consideration, seller notes, escrow, and working-capital adjustments, is how the true economics of an LOI become visible rather than the headline number alone.
A note on scope
This article is educational and general in nature. It is not legal, tax, or financial advice, and it does not describe what any particular owner should do in a specific transaction. LOI terms, exclusivity mechanics, escrow structures, and their tax and liability consequences vary by deal and by jurisdiction, and qualified legal and financial professionals evaluate them against the facts of an individual situation.

Frequently asked questions
- Is a letter of intent legally binding?
- An LOI is usually a hybrid. Most of it, including price, deal structure, working capital, escrow, and earnout terms, is typically non-binding and expresses current intent. A smaller set of provisions, most often exclusivity, confidentiality, expense allocation, and governing law, is generally drafted to be binding. Because courts have enforced entire LOIs as contracts when the drafting was ambiguous, clear labeling of which sections bind matters.
- Why do sellers have the most leverage before signing the LOI?
- Before signing, a seller who ran a competitive process may hold more than one offer and a real ability to walk away. Once exclusivity is granted, competing buyers move on, advisory and legal costs mount, and any term left undefined is drafted by the buyer's counsel. Advisory commentary generally treats signing as the high point of seller leverage, with terms tending to move in the buyer's favor afterward.
- How long is a typical exclusivity or no-shop period?
- In middle-market private-company deals, exclusivity commonly runs 30 to 90 days, with 45 to 60 days often described as typical. Some advisers favor the shorter end, while buyers frequently seek longer or open-ended windows. Limiting automatic extensions and tying continued exclusivity to buyer diligence and financing milestones are common ways the period is structured.
- Which LOI terms matter beyond the headline price?
- Deal structure, working-capital treatment, escrow or holdback size and duration, earnout metrics, the framing of representations and indemnification, and any employment or equity-rollover arrangements all affect how much a seller keeps and when. These non-binding terms are generally easier to shape while competing interest exists than after exclusivity narrows the field.
- What is a re-trade and how does exclusivity relate to it?
- A re-trade is a buyer's attempt to renegotiate price or terms downward late in the process, often during diligence. Exclusivity increases the risk because the seller no longer has a competing buyer to walk to. Structuring exclusivity with milestones and reasonable time limits is one general way deals attempt to reduce that exposure, though outcomes depend on the specific facts.
