What is LOI?

Definition

LOI, or Letter of Intent, is a preliminary document that outlines the principal terms on which two or more parties propose to enter a business transaction. It is commonly used in mergers and acquisitions, investments, real estate transactions, financing arrangements, and strategic partnerships.

An LOI establishes a shared understanding of major commercial terms before the parties invest further time and resources in definitive agreements. Depending on its wording and applicable law, some provisions may be binding while other provisions are intended only as a statement of proposed terms.

Key Components of an LOI

The contents of an LOI depend on the transaction, but a well-structured document generally identifies the parties, describes the proposed transaction, and records the principal commercial terms under discussion.

  • Transaction structure: Describes whether the proposed deal involves an asset purchase, share purchase, investment, merger, financing, or another structure.
  • Consideration: States the proposed purchase price, investment amount, valuation, or other economic terms.
  • Conditions: Identifies due diligence, regulatory approvals, financing, board approval, or other conditions that may apply.
  • Timing: Sets expected milestones for due diligence, definitive documentation, signing, and closing.
  • Confidentiality: Establishes how sensitive transaction information should be handled when the parties have agreed to protect it.

How an LOI Works

The process typically begins when the parties have identified a potential transaction and reached sufficient alignment on its major terms. One party prepares or proposes the LOI, the other party reviews the terms, and both sides negotiate revisions before signing or acknowledging the document.

After the LOI is agreed, the parties generally proceed with activities such as financial, legal, tax, commercial, and operational due diligence. They may then negotiate definitive agreements that contain the detailed legal terms required to complete the transaction.

For example, an acquisition LOI could propose a purchase price of $50 million, subject to due diligence, regulatory approvals, and execution of definitive agreements. The final purchase agreement may subsequently establish detailed representations, warranties, closing conditions, and adjustment mechanisms.

Binding and Non-Binding Provisions

An important feature of an LOI is the distinction between provisions intended to be binding and provisions describing proposed commercial terms. The document should clearly identify which obligations the parties intend to take effect immediately and which remain subject to negotiation.

Common provisions that may be expressly binding include confidentiality, exclusivity, allocation of transaction expenses, access to information, governing law, or dispute-related terms. The commercial terms of the proposed transaction may instead be stated as non-binding indications of the parties' current understanding, subject to definitive documentation.

Loi Confidentiality addresses confidentiality provisions associated with an LOI and explains their relevance to protecting information exchanged during a proposed transaction or business process.

LOI in Financial and Business Decisions

For finance teams, an LOI can provide an early reference point for evaluating the financial implications of a proposed transaction. The stated valuation, consideration, financing assumptions, payment structure, and transaction timing can inform preliminary financial models and planning.

An LOI can also establish the commercial framework used during due diligence. Finance professionals may compare proposed terms with historical financial performance, working capital requirements, debt arrangements, tax considerations, and expected cash flows before the transaction advances to definitive documentation.

LOI vs. Definitive Agreement

An LOI generally summarizes the principal terms under discussion, while a definitive agreement establishes the detailed contractual rights and obligations governing the completed transaction. The definitive agreement typically contains more comprehensive provisions concerning representations, warranties, covenants, conditions to closing, indemnification, payment mechanics, and remedies.

The LOI therefore serves as a transaction roadmap rather than automatically serving as the final legal document. Its exact legal effect depends on its wording, the parties' intentions, and applicable law.

Best Practices for Preparing an LOI

A useful LOI should make the proposed transaction understandable while clearly distinguishing agreed terms from matters that remain subject to negotiation. Finance and business teams should ensure that important economic assumptions are stated consistently with supporting analyses.

  • Clearly identify the parties and proposed transaction structure.
  • State material financial terms and valuation assumptions accurately.
  • Separate binding provisions from non-binding commercial terms.
  • Define key milestones, conditions, and expected transaction timing.
  • Coordinate the LOI with confidentiality, due diligence, financing, and definitive-documentation processes.

Summary

An LOI provides a preliminary framework for a proposed transaction by documenting its principal commercial terms, conditions, timing, and selected obligations. It helps parties organize due diligence and negotiations while creating a reference point for the definitive agreements that may follow.
