Confidentiality in M&A processes: why it is non-negotiable

In the Spanish middle market, where companies are deeply rooted in their communities and rumours travel at the speed of a mid-morning coffee, confidentiality in an M&A process is not a legal formality. It is an existential necessity.

I have seen perfectly viable deals derailed because someone talked. A supplier who found out the company was for sale and began demanding additional guarantees. A competitor who learned of the process and contacted key clients. Employees who heard from third parties and started looking for other jobs. Each of these situations directly destroys business value.

Why confidentiality is so critical

Employees: Uncertainty is productivity’s greatest enemy. Fear of job losses leads to lower performance, higher absenteeism, and the departure of key people.

Clients: When clients learn of a potential ownership change, they wonder whether service will continue at the same level and whether they should seek alternatives.

Suppliers: Those who learn of a possible sale may tighten credit terms or demand advance payments.

Competitors: A competitor who knows a company is in a sale process has an enormous informational advantage.

Banks: Financial institutions may review credit lines or request additional guarantees.

How we manage confidentiality

At Blue Mountain, confidentiality management is a structured process. Initial contacts are always discreet. We sign NDAs before receiving any information. Information is shared only with those who need it. Operations use codenames internally. Meetings are scheduled outside business hours or at off-site locations.

What we ask of the entrepreneur

Limit the circle of knowledge to the absolute minimum (entrepreneur, spouse if applicable, tax adviser, lawyer). Maintain normal behaviour. Manage due diligence carefully with virtual data room access rather than physical visits where possible.

When and how to communicate

There is a moment in every sale process when confidentiality gives way to communication — ideally when the deal is signed or very close to it. Communication to employees is most important and most delicate: direct, honest, and reassuring. Clients and key suppliers receive personalised communication. Well-managed communication can transform a moment of uncertainty into one of renewed confidence.
