The NDA in M&A: More Than a Formality

The Non-Disclosure Agreement (NDA) is the first legal document signed in a business sale. And like everything done first, it tends to be treated with haste. This is a mistake — the NDA is a fundamental piece of seller protection.

When a business owner initiates a sale process, they will share information that may never have left the company: detailed financial statements, client portfolio, product margins, commercial strategy, supplier contracts, management team compensation.

Key clauses that matter: broad definition of confidential information (including verbal, derived, and the existence of discussions), non-use obligation (information only for evaluating the deal, not competing), authorised persons specification, non-solicitation of employees/clients/suppliers, adequate duration (2-3 years typically), destruction obligation if the deal does not complete, and effective penalties (a penalty clause is the most effective deterrent).

Common mistakes: signing the buyer’s NDA without review (it protects the buyer’s interests, not the seller’s), not covering the existence of the sale process (the most sensitive information), using generic templates not designed for M&A, and not requiring NDAs from all potential buyers in a competitive process.

At Blue Mountain, we sign an NDA in every transaction without exception. We treat it as what it is: a serious commitment we assume with the seller. If you are thinking about starting a sale process, the first practical advice: take the NDA seriously, have your lawyer draft it (not accept one), and do not share a single figure until it is signed.

The Human Dimension of M&A

Behind every transaction in the middle-market, there are people making decisions that will affect their lives for years. The business owner contemplating a sale is not just executing a financial transaction — they are letting go of something that has defined their identity, provided their purpose, and shaped their daily existence for decades.

Understanding this human dimension is not optional for the serious investor — it is essential. The deals that close successfully and generate lasting value are overwhelmingly those where both parties feel heard, respected, and fairly treated throughout the process. The deals that fail — or that close but generate conflict afterwards — are those where one or both parties feel that the process was adversarial rather than collaborative.

This does not mean being soft on commercial terms. It means being honest about our position, transparent about our analysis, and respectful of the seller’s legitimate interests and concerns. It means recognising that the best outcome is not one where we extract maximum value from the other side, but one where both sides feel the terms are fair and the relationship has a solid foundation for the years ahead.

Lessons from Experience

After more than fifteen years and hundreds of transactions analysed, certain patterns become clear. The quality of advisers on both sides has a disproportionate impact on outcomes. Well-advised sellers have realistic expectations, organised documentation, and constructive approaches to negotiation. Poorly advised sellers have inflated expectations, chaotic information, and adversarial postures that undermine their own interests.

The timing of transparency matters enormously. Sharing information — about concerns, about reasoning, about limitations — early in the process builds trust and prevents misunderstandings from escalating. Withholding information for tactical advantage almost always backfires, because the middle-market is a small world where reputations are built and destroyed one transaction at a time.

Finally, patience is a genuine competitive advantage. The investor who can wait for the right opportunity, who does not force timelines, and who is willing to walk away from a transaction that does not feel right is the investor who, over a long career, accumulates a portfolio of excellent investments and a reputation that opens doors. In the Spanish middle-market, where relationships matter deeply and word of mouth travels fast, that reputation is perhaps the most valuable asset an investor can possess.
