Short answer: usually, as far as its wording allows
Usually yes, but only as far as its own wording allows. An NDA is a contract, and a contract does not disappear because one party is bought, merged or closed. What matters is the survival clause, the assignment clause and who is left to enforce or be bound. For an advisor, the practical result is that a counterparty's materials often stay restricted well after the deal closes or the doors shut. This is general information, not legal, tax or financial advice.
Because rules differ by state and by contract, treat everything below as a map of the questions to ask, not as an answer for a specific agreement.
What decides whether an NDA keeps binding?
Four clauses do most of the work. Read them in this order.
| Clause | What it controls | Question for the advisor |
|---|---|---|
| Term and survival | How long confidentiality duties last after disclosure or termination | Is the period fixed, open-ended, or tied to trade secrets? |
| Assignment and change of control | Whether the NDA moves to a buyer or ends when ownership changes | Does a merger, stock sale or asset sale need consent? |
| Return or destruction | What must happen to materials when dealings end | Were materials destroyed, and is there a certificate? |
| Permitted use and residuals | What the recipient may do with information it keeps in its head or systems | Does a residuals term widen use? See what a residuals clause means |
Many NDAs set a fixed period, commonly counted in years, with a separate and longer duty for trade secrets. Others have no end date. Do not assume a number; read the clause.
What happens in a stock sale, an asset sale and a merger?
The deal structure changes who is bound, so ask the deal lawyer which one applies.
- In a stock sale, the company that signed the NDA still exists under new ownership, so the NDA generally continues with the same party. Check for change-of-control language anyway.
- In an asset sale, the NDA stays with the selling entity unless it is assigned. A buyer that does not take assignment may have no direct duty to the counterparty, while the seller keeps its own.
- In a merger, the surviving entity often takes on the contracts of the merged entity, but state law, the NDA's assignment terms and its governing-law clause can change that result.
The point for a data-licensing conversation is simple: the person who now controls the archive may hold counterparties' confidential material under duties that were signed years ago by a different entity.
What if the company has shut down or is winding up?
Closing a company does not necessarily end its contractual duties, and state law varies. In an assignment for the benefit of creditors, for example, the company transfers its assets to an assignee who holds them in trust and liquidates them, so the assignee may be the person holding both the records and the NDA duties; state law controls the details. Courts, trustees or assignees may control the records, and any licensing step needs their involvement. Companies that are acquired or wound down can still qualify with SourceX if the data still exists, and a court, trustee or assignee that controls the assets must be part of the process.
Before talking about scope with a wind-down client, collect these:
- The list of NDAs signed with customers, vendors, prospective buyers and investors, with their dates.
- Any deal-room records from earlier sale processes, since those often sit under strict confidentiality terms.
- Return-or-destroy certificates already given.
- The name of whoever now has authority to sign, whether an officer, assignee or trustee.
Why does this matter before a post-deal or wind-down license?
Buyers of licensed data want clean rights. A dataset full of counterparties' confidential material is a liability for everyone in the chain. Sorting by NDA status lets the company exclude restricted counterparties, de-identify others and keep the remainder. The rules for personal data are separate from contract duties, and both can apply at once; see the three commitments behind California's deidentified data definition for the personal-data side and de-identifying free text such as emails and notes where health information is involved.
If recordings are involved, such as service calls, a separate consent question applies, covered in healthcare contact center recordings and licensing.
What to say as an M&A advisor
Keep the message to a question that a seller's counsel can answer quickly.
Advisors who work sell-side can find the broader fit in referral opportunities for M&A advisors. Check your own engagement letter, licensing status and professional rules on referral fees and disclosure before taking part. Advisers who also hold client records may have record-handling duties of their own, as the FTC Safeguards Rule for CPA firms guide illustrates; whether any such rule reaches your files is a question for your counsel.
When should an advisor say no?
Skip or pause when the records belong mainly to counterparties who have not consented, a court or trustee controls the assets and has not been approached, or nobody can say which NDAs exist. A company that cannot identify its confidentiality duties is not deal-ready, though it may be later.
Next step
Ask the client for the NDA list and the survival terms. If the company has 50+ full-time employees at peak (contractors excluded), several years of records and an authorized sponsor, register as a partner and make the introduction, or run the company fit checker first.
