Quick Answer
Before any deal information changes hands, a confidentiality agreement protects both sides. An NDA in acquisitions defines information protection, permitted disclosures, and often standstill provisions—so sensitive data shared during diligence can’t be misused if the deal falls through.
Most sellers hand over their most sensitive data to a prospective buyer — sometimes a competitor — before anything binds that buyer to protect it.
A confidentiality agreement is the first document in most deals, and skipping or rushing it exposes exactly the information a deal requires you to share. It protects you whether or not the deal closes. This guide covers NDAs at the start of an acquisition.
We put confidentiality protections in place before sensitive information moves, because a prospective buyer may also be a competitor. This is general information, not advice on a specific deal.
Problem
Sharing before protecting
Disclosing sensitive data without an NDA risks misuse if the deal falls through.
Solution
Protect it first
An NDA defines what's protected, who may see it, and limits on a walked-away buyer.
Resolution
Safe diligence
You share what the deal needs knowing your information is protected.

The NDA at the start of an acquisition
An NDA in acquisitions binds a prospective buyer to confidentiality before any sensitive information changes hands.
It’s the foundation that makes safe diligence possible, especially when the buyer could be a competitor.

Information protection
Information protection defines what’s confidential and how it must be handled, often covering trade secrets and competitive data.
Cornell’s overview of the trade secret underscores why this protection matters when sharing proprietary information.
Protect vs. expose
Illustrative — not a measured statistic.
Permitted disclosures
Permitted disclosures spell out who on the buyer’s side may see the information — advisors, lenders, key employees — and under what conditions.
Defining this prevents confidential data from spreading beyond those who need it.
Standstill provisions
Some deals add standstill provisions restricting what a prospective buyer can do — like making unsolicited bids — for a period.
These protect a seller from a process being weaponized against them.

Why is a confidentiality agreement important in a deal?
A confidentiality agreement is important because a deal requires sharing sensitive business information, and the prospective buyer may even be a competitor. Before financials, customer lists, and trade secrets change hands, an NDA binds the recipient to protect them. This protects the disclosing party whether or not the deal ultimately closes. Without it, sensitive information could be misused if the deal falls through. The NDA is typically the first document signed in a deal for exactly this reason. This is general information, not advice on a specific transaction.
What does an NDA in an acquisition cover?
An NDA in an acquisition defines what information is confidential, how it must be handled, who may access it, and for how long the obligations last. It typically covers financial data, customer and vendor information, trade secrets, and other competitive details shared during diligence. It also addresses what the recipient must do with the information if the deal doesn't close, such as returning or destroying it. The agreement makes safe diligence possible. Its scope should match the sensitivity of what's being shared.
What are permitted disclosures in an NDA?
Permitted disclosures specify who, on the receiving side, is allowed to see the confidential information and under what conditions. In an acquisition, the buyer usually needs to share information with advisors, lenders, and key employees to evaluate the deal. The NDA defines this permitted circle and often requires those people to be bound by the same confidentiality. Defining permitted disclosures prevents the information from spreading beyond those who genuinely need it. It balances the buyer's need to evaluate with the seller's need to protect.
What is a standstill provision?
A standstill provision restricts what a prospective buyer can do for a defined period, such as making unsolicited offers or acquiring shares. It's used to protect a seller from a confidentiality and diligence process being used against them. For example, it can prevent a party who gained inside knowledge from launching a hostile approach. Standstills are more common in larger or more complex deals. When included, their scope and duration are negotiated as part of the confidentiality arrangement.
When should an NDA be signed in a deal?
An NDA should be signed at the very start of a deal, before any sensitive information changes hands. This is typically the first step once parties decide to explore a transaction. Sharing data first and papering the confidentiality later defeats the purpose, since the information is already exposed. Signing the NDA up front ensures the recipient is bound before they see anything sensitive. Getting this sequence right is basic protection in any deal.
Does an NDA protect me if the deal falls through?
Yes — a properly drafted NDA is designed to protect you whether or not the deal closes. It binds the recipient to keep the information confidential and typically requires them to return or destroy it if the deal ends. This is precisely why the NDA matters: the greatest risk is that a prospective buyer, possibly a competitor, walks away with knowledge of your business. The confidentiality obligations survive the failed deal. Strong drafting ensures the protection holds after the parties part ways.
How can Clark Meyers help with confidentiality agreements?
We start with a free legal-strategy call and prepare or review the confidentiality agreement before sensitive information moves. We define what's protected, who may see it, the obligations on a walked-away party, and any standstill terms. We tailor the protections to the sensitivity of your information and the nature of the counterparty. The goal is safe diligence with your information protected. The first step is simply a conversation, with no obligation, and a specific deal gets individual review.
