In middle-market M&A transactions, the Letter of Intent (LOI) is often treated as a preliminary document, something to move the process forward before the “real” legal agreement is negotiated.
That thinking is a mistake.
For CFOs and financial leaders involved in transactions, the LOI is often the most important negotiation in the entire deal process. Once it is signed, the leverage in the transaction frequently shifts to the buyer, and the economic structure of the deal is largely set.
A well-negotiated LOI can protect value and create a smooth path to closing. A poorly negotiated one can lead to price reductions, prolonged diligence, and a loss of negotiating leverage.
Below are several areas every CFO should focus on when reviewing or negotiating an LOI.
The Myth of the “Non-Binding” LOI
Most LOIs contain language stating that the document is non-binding. While technically true for certain provisions, this phrase often creates a false sense of security.
In most transactions:
Non-binding provisions typically include
- Purchase price
- Deal structure
- Working capital targets
- Earnouts
- Rollover equity
However, several key sections are almost always binding, including:
- Confidentiality
- Exclusivity (no-shop provisions)
- Access to information
- Certain legal provisions such as governing law
This means that although the price may technically be non-binding, the seller may be contractually prevented from negotiating with other buyers. For CFOs advising ownership or boards, understanding this distinction is critical.
Exclusivity: Where Leverage Changes
The exclusivity clause, often called the no-shop provision, is one of the most important elements of the LOI.
Once exclusivity begins, the seller agrees not to:
- Solicit other offers
- Negotiate with competing buyers
- Provide diligence information to other parties
Typical exclusivity periods range from 60 to 120 days, which is often longer than necessary. From a negotiating standpoint, exclusivity creates a significant shift in leverage. Once competitive tension disappears, buyers may attempt to renegotiate certain terms during diligence.
For CFOs managing the process, several best practices are worth considering:
- Keep exclusivity as short as reasonably possible (often 30–45 days).
- Tie extensions to specific diligence milestones.
- Ensure the buyer has adequate resources committed to move the process quickly.
Maintaining momentum is critical once exclusivity begins.
The LOI Is Where Deal Economics Are Set
Although the definitive purchase agreement contains the detailed legal language, the economic framework of the deal is usually established in the LOI.
For that reason, CFOs should ensure several key items are clearly defined before signing.
Purchase Price Structure
The headline price rarely tells the full story.
The LOI should clearly outline:
- Cash at closing
- Rollover equity
- Earnout provisions
- Seller notes or deferred payments
These elements determine the actual value received by shareholders.
Working Capital Targets
Working capital adjustments are one of the most common sources of post-LOI disputes.
Important questions include:
- How is working capital defined?
- What historical period is used to determine the working capital peg?
- Are seasonal adjustments required?
Ambiguity in these definitions can materially affect the effective purchase price.
Debt and Cash Treatment
Most deals are structured as cash-free, debt-free, but the definitions matter.
The LOI should clarify:
- What debt must be repaid at closing
- Whether excess cash remains with the seller
- How transaction expenses are treated
Managing the Diligence Process
Another common issue with LOIs is open-ended diligence. Buyers often request broad access to financial, legal, operational, and environmental information without a clearly defined timeline.
Without structure, diligence can expand indefinitely, which can create deal fatigue and extend exclusivity beyond the intended timeframe.
A well-structured LOI should establish:
- Expected diligence timeline
- Scope of diligence categories
- Buyer commitment to proceed in good faith
For CFOs managing the internal process, this structure can help maintain focus and momentum.
The Risk of a “Re-Trade”
A re-trade occurs when a buyer attempts to renegotiate the purchase price or key terms after the LOI has been signed. Sometimes this is justified, for example, when diligence uncovers previously unknown issues.
However, re-trades also occur because the seller has already granted exclusivity and restarting the process can be costly and time-consuming.
Ways to reduce re-trade risk include:
- Running a competitive process before signing the LOI
- Negotiating key financial definitions early
- Limiting exclusivity periods
- Maintaining clear financial transparency during diligence
Experienced advisors can also play a key role in protecting deal value.
The CFO’s Role in the LOI Process
For many organizations, the CFO becomes the central figure in managing the transaction process.
This includes:
- Validating financial assumptions
- Defining working capital and EBITDA adjustments
- Managing the diligence process
- Protecting shareholder value during negotiations
Because of this, CFO involvement early in the LOI stage can significantly influence the outcome of the deal.
The LOI Is Not Just a Formality
Although a Letter of Intent is often only a few pages long, it establishes the framework for the entire transaction.
For CFOs and financial leaders, the key takeaway is straightforward:
The LOI is not a formality, it is one of the most important negotiations in the deal process.
Handled thoughtfully, it creates alignment and momentum toward closing. Handled poorly, it can shift leverage and lead to difficult renegotiations later in the process.
Approaching the LOI with the same rigor applied to the final purchase agreement can help ensure that the transaction proceeds on the terms originally envisioned.
FAQs
What is the primary purpose of a Letter of Intent (LOI) in an M&A transaction?
An LOI outlines the proposed terms of a transaction before a definitive purchase agreement is drafted. It serves as a roadmap for negotiations, diligence, and deal execution.
Is a Letter of Intent legally binding?
Most LOIs are only partially binding. While business terms such as purchase price may be non-binding, provisions related to confidentiality, exclusivity, and certain legal matters are often enforceable.
Why is the exclusivity clause so important?
Exclusivity prevents the seller from negotiating with other potential buyers for a specified period. Once exclusivity begins, the seller's leverage often decreases because competitive bidding is removed from the process.
What are working capital adjustments, and why do they matter?
Working capital adjustments ensure the business is delivered with an agreed-upon level of operating capital at closing. Poorly defined working capital targets can lead to disputes and changes to the final purchase price.
What is a re-trade in an M&A transaction?
A re-trade occurs when a buyer attempts to renegotiate price or deal terms after the LOI has been signed, often during the diligence phase. Strong preparation and clear LOI language can help reduce this risk.
How can CFOs add value during the LOI stage?
CFOs play a critical role in validating financial assumptions, defining key metrics, managing diligence, negotiating financial terms, and helping protect shareholder value throughout the transaction process.
When should a company involve its CFO in an M&A process?
Ideally, CFO involvement should begin before the LOI is signed. Early participation allows financial leaders to identify risks, evaluate deal structures, and negotiate terms before leverage shifts to the buyer.
