The Role of LOIs and NDAs in M&A Legal Planning
Before an acquisition agreement is signed, before due diligence begins, and often before a buyer even sees financial statements, two legal tools usually shape the early stages of a merger or acquisition:
Non-Disclosure Agreements (NDAs) and Letters of Intent (LOIs).
These documents may seem preliminary compared to the final purchase agreement, but they play a critical role in protecting both parties and setting the foundation for the transaction.
In many ways, NDAs and LOIs establish the rules of engagement for the entire deal process.
For founders exploring a sale, understanding these documents is essential. The wrong terms in an NDA can limit your options with other buyers. A poorly structured LOI can lock you into unfavorable negotiations before the deal is fully understood.
In The Entrepreneur’s Exit Playbook (https://amzn.to/40ppRpT), I explain that founders should treat these early documents with the same seriousness as the final agreement. Because once the deal process begins, the momentum created by an LOI can shape the direction of the entire transaction.
Why NDAs Come First in M&A Deals
In most transactions, the very first legal document signed between the buyer and seller is a Non-Disclosure Agreement (NDA).
An NDA protects confidential information shared during the early stages of a potential acquisition.
When buyers evaluate a company, they typically request sensitive data such as:
- Financial statements
- Customer lists
- Strategic plans
- Technology documentation
- Product roadmaps
- Supplier agreements
Without an NDA in place, sharing this information could expose the business to significant risks.
A properly structured NDA ensures that potential buyers cannot use confidential information for competitive purposes or disclose it to outside parties.
For founders, this protection is particularly important when the buyer is:
- A competitor
- A strategic acquirer in the same industry
- A financial sponsor evaluating multiple targets
Key Provisions in an NDA
Although NDAs are relatively short documents, several provisions are especially important in M&A contexts.
Definition of Confidential Information
The agreement must clearly define what constitutes confidential information.
This usually includes both written and verbal information shared during discussions.
A broad definition helps ensure sensitive data remains protected throughout the process.
Permitted Use of Information
NDAs specify that confidential information can only be used for the purpose of evaluating the potential acquisition.
This prevents buyers from using the information to compete directly with the seller.
Non-Solicitation Provisions
Some NDAs include provisions preventing buyers from soliciting employees, customers, or vendors after reviewing confidential information.
These clauses protect sellers from potential disruption if the deal does not move forward.
Duration of Confidentiality
The agreement also defines how long the confidentiality obligations remain in effect.
Typical durations range from two to five years, depending on the nature of the information.
The Purpose of the Letter of Intent (LOI)
Once initial discussions progress and both parties express serious interest in a transaction, the next step is usually the Letter of Intent (LOI).
An LOI outlines the proposed terms of the acquisition before drafting the definitive agreement.
It provides a framework for negotiating the transaction and signals that both parties intend to move forward.
Typical LOI provisions include:
- Purchase price or valuation range
- Deal structure (asset vs stock purchase)
- Payment terms (cash, rollover equity, earnouts)
- Due diligence timeline
- Proposed closing timeline
Although the LOI is generally non-binding, it creates alignment on the key economic terms of the deal.
Binding vs Non-Binding Terms in an LOI
Most LOIs contain a mix of binding and non-binding provisions.
Non-binding provisions usually include:
- Purchase price
- Transaction structure
- Preliminary deal assumptions
Binding provisions typically include:
- Confidentiality
- Exclusivity
- Governing law
- Break-up protections in certain cases
The exclusivity clause is particularly important.
It usually requires the seller to negotiate only with the buyer for a defined period—often 60 to 120 days—while due diligence is conducted.
This gives the buyer confidence that they can invest time and resources into diligence without competing bidders emerging during the process.
However, for sellers, exclusivity can limit leverage if the deal stalls or terms change.
Why LOIs Shape the Entire Deal
Even though LOIs are technically non-binding in many respects, they strongly influence the outcome of the transaction.
Once the parties agree on headline terms, the negotiation tends to focus on refining details rather than renegotiating the core economics.
For founders, this means the LOI stage is often the most important moment to negotiate key terms such as:
- Purchase price
- Earnout structure
- Equity rollover
- Employment agreements
- Governance rights
If these elements are not addressed early, they may become difficult to renegotiate later.
The Transition From LOI to Due Diligence
Once the LOI is signed, the transaction enters the due diligence phase.
During this stage, the buyer conducts an in-depth review of the company.
The seller typically provides access to documents through a secure data room, including:
- Financial records
- Tax filings
- Customer contracts
- Employee agreements
- Intellectual property documentation
- Corporate governance records
The purpose of diligence is to confirm that the assumptions underlying the LOI are accurate.
If major issues arise during diligence, the buyer may attempt to renegotiate terms or request additional protections.
Strategic Considerations for Founders
Founders should approach NDAs and LOIs strategically rather than treating them as routine paperwork.
An NDA should protect the company’s sensitive information without unnecessarily restricting the seller’s ability to explore other opportunities.
Similarly, the LOI should reflect thoughtful negotiation around the economic structure of the deal.
At Legacy Advisors (https://legacyadvisors.io/), we often remind founders that the LOI is where the direction of the deal is established.
If the key terms are negotiated properly at this stage, the rest of the transaction tends to move more smoothly.
If not, founders may find themselves renegotiating fundamental issues later in the process.
The Bottom Line
NDAs and Letters of Intent serve as the legal gateway into the M&A process.
They protect confidential information, define expectations between buyer and seller, and establish the foundation for negotiating the final transaction.
For founders navigating an acquisition, understanding these documents is essential.
Because the structure and terms set early in the process often shape the outcome of the deal long before the final agreement is signed.
Frequently Asked Questions About The Role of LOIs and NDAs in M&A Legal Planning
Why are NDAs necessary before sharing information with a potential buyer?
Non-Disclosure Agreements (NDAs) are essential because they allow founders to share sensitive information with potential buyers without exposing the business to unnecessary risk. Early in an acquisition process, buyers often request detailed insights into the company’s financial performance, customer relationships, product roadmap, and strategic plans.
Without an NDA in place, there would be little legal protection preventing a potential buyer—especially a competitor—from using that information for their own advantage if the deal does not move forward. For example, they could use pricing strategies, supplier relationships, or product insights to compete more effectively against the company.
An NDA legally restricts the buyer from using the shared information for any purpose other than evaluating the potential transaction. It also limits how the information can be shared within the buyer’s organization and typically requires confidentiality obligations for advisors such as lawyers or accountants.
In short, NDAs create a safe environment for serious acquisition discussions while protecting the seller’s intellectual property, strategy, and competitive position.
What is the main purpose of a Letter of Intent in an M&A transaction?
A Letter of Intent (LOI) serves as a framework for negotiating the acquisition before drafting the final purchase agreement. It outlines the preliminary terms that both parties agree to pursue while due diligence and legal documentation are prepared.
The LOI typically includes the proposed purchase price, deal structure, payment terms, expected timeline for due diligence, and key assumptions about how the transaction will be completed. By establishing these terms early, both the buyer and seller can confirm that they are aligned before investing significant time and resources into the full transaction process.
Although most economic terms in an LOI are technically non-binding, they create a strong expectation that the deal will proceed according to those parameters. Because of this, the LOI stage often represents one of the most important negotiation points in the entire transaction.
Once an LOI is signed, both sides typically move forward with due diligence and preparation of the definitive purchase agreement.
Are Letters of Intent legally binding?
Most Letters of Intent contain a mixture of binding and non-binding provisions.
The economic terms—such as the purchase price, transaction structure, and payment method—are usually non-binding. This means either party can theoretically walk away from the deal if due diligence reveals new information or if negotiations break down.
However, several provisions in an LOI are typically binding. These may include confidentiality obligations, governing law, dispute resolution terms, and most importantly, exclusivity clauses.
Exclusivity prevents the seller from negotiating with other buyers for a specific period of time, often between 60 and 120 days. This gives the buyer confidence to invest resources into due diligence without fear that another bidder will suddenly appear.
Because certain provisions are legally enforceable, founders should review LOIs carefully with experienced advisors before signing.
What risks should founders watch for when signing an LOI?
One of the most significant risks founders face when signing an LOI is losing negotiation leverage too early in the process.
Once an exclusivity period begins, the seller typically agrees not to pursue discussions with other buyers. If the original buyer later attempts to renegotiate the purchase price or key terms during due diligence, the seller may have limited alternatives.
Another potential risk involves vague or incomplete terms within the LOI. If the document does not clearly define major deal elements—such as earnouts, equity rollover requirements, or post-sale employment expectations—those issues may become contentious later during the drafting of the definitive agreement.
Founders should also be cautious about overly long exclusivity periods, which can stall the sale process if negotiations slow down.
Carefully structuring the LOI helps ensure that the deal process moves forward efficiently while preserving the seller’s leverage.
How do NDAs and LOIs work together during an acquisition process?
NDAs and LOIs serve different but complementary roles in the early stages of an M&A transaction.
The NDA is typically signed first. It establishes confidentiality protections that allow the seller to share sensitive information with the buyer during preliminary discussions and early diligence. Without this protection, the seller would risk exposing proprietary information before confirming the buyer’s seriousness.
Once both parties have had enough initial conversations and a buyer demonstrates serious interest, the LOI comes into play. The LOI outlines the proposed structure and economic terms of the acquisition and signals a commitment to move forward toward a final agreement.
Together, these documents guide the transition from exploratory discussions to a structured transaction process. The NDA protects information while the LOI defines the roadmap for negotiating the deal.
Understanding how these documents interact helps founders manage the early stages of the acquisition process with greater confidence and strategic control.
