Letter of Intent (LOI)

A letter of intent (LOI) is a written document that expresses one party’s intention to enter into a formal agreement with another. In business transactions, an LOI outlines the key terms of a proposed deal before the parties commit to full legal documentation. It signals serious interest, establishes a shared framework for negotiation, and often triggers the due diligence process. An LOI is typically not legally binding in its entirety, though specific provisions such as confidentiality and exclusivity clauses are commonly made binding.

Common uses of letters of intent

LOIs appear across many types of business transactions. In mergers and acquisitions, the buyer submits an LOI to the seller outlining the proposed purchase price, deal structure, and conditions to closing. This document allows both parties to confirm alignment on key terms before investing significant time and cost in due diligence and legal documentation. If the LOI reveals fundamental disagreements about valuation or structure, it is far less costly to discover this before full engagement than after [1].

LOIs are also used in real estate transactions, commercial lease negotiations, joint venture formations, licensing agreements, and strategic partnerships. In each case, the LOI serves the same function: creating a documented record of intent and key terms that guides subsequent formal negotiation. A well-drafted LOI reduces the risk that parties will have different recollections of what was agreed in preliminary discussions [2].

In the context of business financing, lenders and investors sometimes issue LOIs to borrowers and founders indicating their intent to provide funding subject to due diligence and documentation. This gives the recipient enough confidence to continue operations or make commitments to third parties while formal documents are being prepared [3].

Key components of a business LOI

A typical M&A letter of intent includes several standard sections. The purchase price section specifies the proposed consideration, including whether payment will be in cash, stock, or a combination, and whether any portion is contingent on future performance through an earnout provision. The deal structure section describes whether the transaction is structured as an asset purchase or a stock purchase, which has significant implications for tax treatment and liability assumption [4].

The conditions to closing section lists what must occur before the transaction can be completed: satisfactory completion of due diligence, receipt of required regulatory approvals, absence of material adverse changes in the target business, and execution of definitive agreements. The timeline section establishes target dates for due diligence completion, definitive agreement signing, and expected closing [5].

The exclusivity or no-shop provision is one of the most commercially significant elements of an LOI. This clause prohibits the seller from soliciting or entertaining competing offers for a defined period, typically 30 to 90 days, giving the buyer time to complete due diligence and finalize documentation without competitive interference. The length and scope of the exclusivity period is often a negotiating point, as sellers prefer shorter exclusivity to preserve optionality [6].

Binding versus non-binding provisions

The enforceability of an LOI is nuanced. Most LOIs explicitly state that the document as a whole is non-binding and does not create a legal obligation to complete the transaction. The parties retain the right to walk away at any point before executing definitive agreements. This non-binding character is important because it allows either party to withdraw if due diligence reveals issues or if negotiations break down without creating breach of contract liability [7].

However, specific provisions within an LOI are routinely made legally binding. Confidentiality obligations protect sensitive information shared during due diligence from being disclosed or used for purposes other than evaluating the transaction. Exclusivity provisions are binding to prevent the seller from shopping the deal. Break-up or termination fee provisions, when included, are binding and require the party that withdraws to compensate the other for costs incurred [1].

Courts in some jurisdictions have found that even nominally non-binding LOIs can create enforceable obligations to negotiate in good faith if the conduct of the parties suggests they intended to be bound. This risk can be managed through careful drafting that clearly identifies which provisions are binding and which are not [8].

LOI versus memorandum of understanding

A memorandum of understanding (MOU) is functionally similar to an LOI and the two terms are sometimes used interchangeably, though distinctions exist in practice. An LOI is typically used when one party has made an offer that the other is considering accepting, and it often reads more like a term sheet. An MOU tends to be more bilateral in language and is more common in government, nonprofit, and international business contexts where neither party is making a unilateral offer [9].

Both documents occupy the same space in the deal timeline: they come after initial discussions have produced enough alignment to justify formal documentation, but before the parties are ready to execute final binding agreements. The practical choice between LOI and MOU often reflects industry convention rather than meaningful legal distinction [4].

LOI in the consulting and advisory context

For business owners considering a sale, the receipt of an LOI from a qualified buyer is a significant milestone. Advisors help clients evaluate LOIs across multiple dimensions: not just the proposed price but the deal structure, conditions, buyer’s financial capability, and the reasonableness of the due diligence timeline and scope. A high-priced LOI with aggressive conditions or an unrealistic timeline may be less attractive than a lower-priced offer with clean terms [5].

Management consultants and M&A advisors also help clients understand what information will be required during the due diligence process that follows LOI execution. Preparing a data room, organizing financial records, and resolving known issues before due diligence begins are all steps that improve the likelihood of the deal closing at the terms stated in the LOI. Surprises discovered during due diligence often trigger price reductions or deal termination [2].

The SEC’s financial statement education resources note that buyers and their advisors conduct rigorous review of a target’s financial statements as part of due diligence following LOI execution, which is why accurate and well-documented financial records are among the most important assets a business owner can maintain throughout the life of the business, not just in anticipation of a sale [10].

Negotiating an LOI

The negotiation of an LOI sets the tone for the entire transaction. Buyers want to lock in favorable terms and secure exclusivity before the seller can generate competing interest. Sellers want to retain flexibility and avoid being bound to a buyer who may not perform. The negotiation of an LOI involves balancing these competing interests across several dimensions: price, structure, exclusivity duration, due diligence scope, and conditions to closing [6].

Price negotiation in an LOI often focuses not just on the headline number but on the components that make up total consideration. Enterprise value is the starting point, but adjustments for working capital, debt, and cash at closing can significantly affect the net proceeds a seller receives. Sellers should understand the difference between enterprise value and equity value before agreeing to a price stated in an LOI, as a transaction priced at enterprise value may deliver substantially less equity value if the business carries significant debt [1].

Due diligence scope negotiation defines what the buyer has the right to examine and for how long. A broad scope with a long timeline gives the buyer maximum information and flexibility to find reasons to adjust price or walk away. A narrow scope with a short timeline favors the seller by limiting the buyer’s ability to identify issues. Sellers who have prepared a comprehensive data room in advance can negotiate for a tighter due diligence timeline because the information will be readily accessible [5].

Common LOI mistakes

Sellers frequently make the mistake of treating the LOI as a near-final agreement and reducing their attention to maintaining business performance during the period between LOI and close. A material adverse change in the business during this period gives the buyer grounds to renegotiate or walk away. Sellers should continue to run their businesses as if no transaction is underway, maintaining customer relationships, managing expenses, and retaining key employees throughout the transaction process [7].

Buyers sometimes make the opposite mistake: treating the LOI as a commitment to close and reducing their diligence rigor once exclusivity is secured. Due diligence that uncovers a significant liability, a customer concentration risk, or an accounting irregularity after the LOI is signed puts the buyer in the difficult position of either accepting an unfavorable deal or walking away after significant investment in the transaction process. Rigorous upfront diligence on the issues most likely to affect valuation reduces this risk [4].
