Engagement formats
Three formats tailored to the transaction's stage
The right format depends on the transaction's stage, the time available and the size of the deal. All three are complementary and can be combined in phased transactions.
Red Flag DD
Full Memorandum
Vendor DD
Post-DD structuring
SPA clauses that protect the investor post-closing
Due diligence doesn't end with the report. Its findings are translated into the Share Purchase Agreement (SPA) through five protection mechanisms that limit the buyer's exposure and allocate the identified risks.
Representations & Warranties
Representations and warranties given by the seller regarding the company's status at closing: accuracy of financial statements, ownership of assets, absence of undisclosed litigation, and regulatory compliance. Breaches create post-closing liability during the survival period (usually 18-24 months for general warranties; up to the statute of limitations for tax and environmental ones).
Specific indemnities
Specific compensation obligations negotiated for known liabilities identified during DD: ongoing tax contingencies, environmental penalties pending finality, labour disputes at an advanced stage. Unlike R&Ws, they do not require proving breach of a warranty: the mere materialisation of the liability triggers the payment obligation.
Deferred contingent price
A price component deferred and contingent on post-closing business targets being met (EBITDA, revenue, contracts closed). Reduces the buyer's risk in transactions with high uncertainty over future performance. Requires precisely defining calculation mechanisms, measurement periods and the buyer's oversight rights to avoid disputes.
Deposit retention
Part of the price retained in an escrow account (usually 10-20%) for a defined period (12-24 months) as security for compliance with the R&Ws and indemnities. It is released to the buyer if justified claims arise; to the seller if the period elapses with no claims. Replaces the buyer directly withholding the price.
Representations & Warranties Insurance
An insurance policy that transfers the risk of breach of the seller's warranties to the insurer. Especially recommended in transactions above €20M, private equity processes where the seller needs full liquidity after closing, and transactions with particular environmental or regulatory uncertainty. Usual premium: 1-3% of the insured amount. Compatible with Vendor DD.
RD 571/2023 · Foreign investment screening
FDI Screening: the check that cannot be skipped
For investments by non-EU residents, FDI Screening is an additional layer that must be resolved before the transaction closes. Due diligence identifies whether the target falls within the screening perimeter and how much time must be set aside for authorisation.
Three simultaneous conditions (RD 571/2023)
- The investor does not reside in the European Union
- The acquisition exceeds 10% of the Spanish company's share capital
- The company operates in a strategic sector: energy, defence, critical infrastructure, sensitive data, biotechnology, media or artificial intelligence
If all three conditions are met simultaneously:
The transaction cannot be closed without prior authorisation from the Council of Ministers. Non-compliance results in the transaction being void and may lead to administrative penalties. Processing usually takes between 3 and 6 months. This contingency should be built into the M&A process timeline from the outset and reflected in the SPA's conditions precedent.
Frequently asked questions about M&A due diligence in Spain
How long does legal due diligence take in Spain?
The usual timeline ranges from 3 to 8 weeks depending on the scope and size of the company. A Red Flag DD can be completed in 1-2 weeks. A comprehensive full memorandum takes between 3 and 8 weeks depending on the volume of the data room and regulatory complexity. Environmental and regulatory due diligence usually take the longest in Spain due to the volume of regional authorisations and the fragmented regulatory landscape.
What is the difference between a Red Flag DD and a full memorandum?
The Red Flag DD identifies only the critical risks that could block the transaction or require a significant price renegotiation. It is faster (1-2 weeks) and is used for pre-LOI decisions or in competitive processes. The full memorandum comprehensively analyses the 6 dimensions, classifies all risks, and provides detailed recommendations for structuring the SPA. It is the base document for negotiating R&Ws and indemnities.
What are R&Ws in a company sale and purchase agreement?
Representations and Warranties are the representations and guarantees the seller gives regarding the company's status at closing: accuracy of financial statements, ownership of assets, absence of undisclosed litigation, regulatory compliance and validity of contracts. If they prove false or incomplete, they create seller liability during the survival period (usually 18-24 months for general warranties; up to the statute of limitations for tax and environmental ones).
When is FDI Screening mandatory for an acquisition in Spain?
Under Royal Decree 571/2023, prior authorisation from the Council of Ministers is mandatory when the following apply simultaneously: the investor does not reside in the EU, the acquisition exceeds 10% of share capital, and the company operates in a strategic sector (energy, defence, critical infrastructure, sensitive data, biotechnology, media or artificial intelligence). Authorisation must be obtained before closing. Proceeding without it renders the transaction void.
For what type of transactions is RWI Insurance recommended?
RWI Insurance is especially recommended for: transactions above €20M, competitive processes where the seller does not want to retain post-closing liability, private equity funds needing full liquidity after closing, and transactions with particular environmental or regulatory uncertainty. The usual premium ranges from 1% to 3% of the insured amount. It is compatible with Vendor DD and enables faster closings.
