An NDA must control use, not only disclosure
A buyer can protect secrecy and still misuse sensitive information.
Most owners read an NDA as a promise that the buyer will not disclose confidential information. That is necessary, but it is not sufficient.
The more important question is how the buyer may use the information. A strategic competitor could keep information confidential and still use customer economics, pricing, employee compensation, product plans, or operating methods to improve its own position.
A transaction-specific agreement should therefore limit use of the information to evaluating the proposed transaction. It should define who may receive it, make the buyer responsible for its representatives, restrict direct contact with employees, customers, and suppliers, and require return or destruction if discussions end. Depending on the parties, it may also need clean-team procedures for competitively sensitive data.
The agreement should address compelled disclosure, residual electronic copies, the duration of obligations, and the fact that neither party is obligated to complete a transaction. It should not contain broad language that unintentionally grants rights to information or limits the seller's ability to run a process.
An NDA cannot eliminate risk. Enforcement occurs after a breach, when damage may already be difficult to reverse. That is why the agreement must be paired with staged disclosure. Share only what the buyer needs at each phase, and reserve the most sensitive information for the point at which value, structure, financing, and seriousness have been established.
Confidentiality is a system. The NDA is one control within that system, not permission to open the entire data room.
