The Basic Mechanics of an LOI in an M&A Transaction

At Diedrich Consulting, we treat the LOI as a critical control point: well-written LOIs reduce renegotiation, preserve leverage, and keep diligence focused. Here are the core mechanics you should understand.

---

What an LOI Is (and Is Not)

An LOI is typically a non-binding document that outlines the principal terms of a proposed acquisition, merger, or asset purchase.

What it is: a roadmap + a set of business commitments-in-principle
What it isn’t: a purchase agreement (and it shouldn’t try to be one)

That said, most LOIs include certain binding provisions, usually around confidentiality, exclusivity, expenses, and governing law.

The Core Sections of a Strong LOI

1) Parties and Transaction Overview

The LOI should clearly identify:

• buyer and seller entities
• what’s being acquired (stock, assets, subsidiary, merger)
• the intended closing structure (often subject to tax, diligence, and legal review)

This sounds basic, but mistakes here can create costly confusion later—especially when there are holding companies, multiple subsidiaries, or minority holders.

---

2) Purchase Price and Consideration

This is the headline term, but it’s rarely just one number. LOIs should specify:

• Total consideration (enterprise value vs equity value, where relevant)
• Form of consideration: cash, seller note, earnout, rollover equity, stock swap, assumption of liabilities
• Timing: closing vs deferred payments
• Adjustments: working capital true-up, net debt, cash on hand, inventory adjustments

Tip: If price depends on a metric (EBITDA, revenue, users), the LOI should at least define the metric at a high level. Ambiguity breeds renegotiation.

---

3) Structure: Stock Purchase vs Asset Purchase vs Merger

The LOI should state the expected structure and why it works for the deal:

• Stock purchase: buyer inherits entity history (and liabilities), simpler continuity
• Asset purchase: buyer picks assets/liabilities, usually stronger liability isolation
• Merger: often used for structural or statutory reasons, can be “triangular” for flexibility

Even if final structure is “to be mutually agreed,” it should be directionally stated so tax and diligence teams aren’t guessing.

4) Key Conditions to Closing

This is where deals live or die. Typical LOI conditions include:

• completion of due diligence (financial, legal, operational)
• negotiation/execution of definitive agreements
• board and shareholder approvals (if required)
• regulatory approvals (industry-specific, antitrust, foreign investment, etc.)
• financing contingency (if buyer needs it)
• no material adverse change (MAC) between signing and closing

The LOI should be honest: if financing is required, say it. If you need consents (customers, landlords, lenders), note it early.

---

5) Diligence Scope and Process

LOIs should include a practical diligence framework:

• data room access and expectations
• management meetings and site visits
• third-party consents needed for diligence
• how requests will be handled and by whom
• timeline to complete diligence and move to definitive docs

This reduces friction and keeps the “discovery phase” from becoming open-ended.

---

6) Exclusivity (Often Binding)

Exclusivity (“no shop”) means the seller agrees not to solicit or negotiate with other buyers for a period of time.

Key points to define:

• exclusivity length (e.g., 30–90 days)
• what activities are prohibited
• whether existing discussions must be terminated
• what happens if seller breaches

Exclusivity is valuable to the buyer because it protects time and diligence spend. For sellers, it should be earned—usually with credible terms and a real timeline.

---

7) Confidentiality (Often Binding)

Even if there’s already an NDA, LOIs often reaffirm confidentiality and add:

• limits on public announcements
• rules for contacting employees, customers, suppliers
• how sensitive documents are handled
• return/destruction of information if deal ends

---

8) Governance and Control (If There’s Rollover Equity or Stock Consideration)

If the seller is rolling equity, taking a note, or receiving stock, the LOI should address:

• post-closing roles (employment/consulting)
• board seats or observer rights
• information rights
• protective provisions (major decisions requiring consent)

This is especially important in partial liquidity deals where the seller remains economically exposed.

---

9) Earnouts and Contingent Payments

Earnouts can bridge valuation gaps, but they also create disputes. LOIs should define:

• the metric (revenue, EBITDA, gross profit, milestones)
• measurement period
• governance around the business during earnout
• reporting and dispute resolution
• caps/floors and acceleration triggers (optional)

Even a simple outline here prevents months of pain later.

---

10) Timeline, Signing/Closing Targets, and Drop-Dead Dates

LOIs should include:

• expected date for definitive agreements
• target close date
• “drop-dead” date if the deal hasn’t progressed
• key milestones (diligence complete, financing complete, drafts exchanged)

Time kills deals. LOIs should fight that.

---

11) Break Fees, Expense Reimbursement, or Deposits (Optional)

Depending on deal size and leverage, parties may include:

• who pays professional fees
• whether buyer expenses are reimbursed if seller walks without cause
• deposits or escrow terms (less common in standard M&A, more common in certain assets)

---

12) Binding vs Non-Binding Language

This is critical. A well-drafted LOI clearly states:

• which sections are binding (usually confidentiality, exclusivity, fees, governing law)
• that the rest is non-binding
• that no obligation exists until definitive agreements are executed

This reduces “accidental contract” risk and protects both parties.

---

Common LOI Mistakes (That Cost Real Money)

• Vague purchase price mechanics (no debt/working capital clarity)
• Earnouts without definitions
• No control over leaks / customer contact
• Exclusivity with no timeline (seller stuck, buyer slow-rolls)
• Over-lawyering (LOI becomes a mini-purchase agreement)
• Under-lawyering (LOI is too thin and invites renegotiation)
