One of the greatest concerns for business owners in a sale process is not the valuation — it is the question of who finds out about the sale plans, and when. Premature disclosure can have devastating consequences: key employees hand in their notice, customers proactively switch to alternative suppliers, and existing suppliers renegotiate terms from a position of strength. Conversely, disclosing too late can breach legal obligations and cause lasting damage to trust. Managing the flow of information is an art — and it follows one clear principle: need-to-know.
Why Confidentiality Is So Critical
During a business sale, the company operates in a state of uncertainty for many months. Employees who learn too early about an impending change of ownership react with anxiety — and anxiety leads to attrition. High performers have the best alternatives available to them and are typically the first to act on them. A business that loses its top sales executive or chief developer mid-process is, by the time of Due Diligence, a fundamentally different proposition.
The same applies to customers: if a key client learns the business is up for sale, they may begin evaluating alternatives — not out of malice, but out of prudent commercial caution. And suppliers who become aware of an impending change of ownership will enter the next contract negotiation with a very different hand.
The NDA: The Foundation of Confidentiality
Before anyone outside the inner circle is informed, a robust Non-Disclosure Agreement (NDA) — also known as a confidentiality agreement — must be in place. A well-drafted NDA covers considerably more than the obvious. It should include at least the following provisions:
- Purpose limitation: Information received may only be used for the purpose of evaluating the transaction — not for competitive purposes.
- Return and deletion obligations: Upon termination of negotiations, all documents provided must be returned or verifiably destroyed.
- Non-solicitation clause: The prospective acquirer is prohibited from approaching or soliciting employees of the target business — both during and for a defined period after the process.
- Duration and penalties: A minimum term of 24 months, with clearly defined contractual penalties for any breach.
The Four Phases of Staged Disclosure
Professionally managed sale processes follow a clear, phased approach — the further the process advances, the broader the circle of those informed:
The intention remains strictly within the inner circle. No employee, no tax adviser, no external legal counsel beyond those directly engaged is aware of the process.
Once a credible acquirer has signed a letter of intent, the CFO, head of accounting and, where appropriate, legal counsel are brought in to assist with Due Diligence preparation — all under NDA.
Following execution of the SPA, senior management and key contributors are informed. At this point, planning for the internal communication ahead of closing also commences.
Only after the transaction has completed is the wider audience informed — via carefully prepared communications that emphasise continuity and stability.
Statutory Obligations: What Cannot Be Ignored
In an asset deal (acquisition of individual assets rather than shares), Section 613a of the German Civil Code (BGB) applies: employees must be informed of the transfer of undertaking and have a right of objection. This notification must occur prior to the transfer — there is no discretion here. Where a works council (Betriebsrat) exists, it also has rights of information and consultation under Section 111 of the Works Constitution Act (BetrVG) in the event of material operational changes — which a business sale typically constitutes.
Client Communications: Elements of a Professional Strategy
The message to clients should never be reactive — it should be planned, coordinated and positively framed. A professional communications strategy will include: a clear statement of continuity in the business relationship, an introduction to the new owner that highlights their strengths, a personal note from the outgoing proprietor, and a named point of contact on the acquirer's side. What clients want to hear is not who has bought the business, but that their orders, their terms and their relationships are secure.
The most common mistake in a sale process is not inadequate preparation — it is premature, uncontrolled disclosure. Once out, a rumour cannot be recalled.
