How to sell a company in Spain: step-by-step guide 2026

# How to sell a company in Spain: step-by-step guide 2026

For most owners, selling a company is the biggest financial transaction of their working life, and it rarely happens twice. Unlike day-to-day management, a company sale demands specific preparation, a thorough understanding of the process and a negotiation that can run for months. Improvising has direct consequences: deals that collapse during due diligence, valuations below what the business is really worth or contract clauses that create unexpected liabilities years after completion.

The market backdrop is favourable. Spain is going through an intense cycle of mergers and acquisitions: according to the annual transactional market report from TTR Data, the Spanish M&A market saw thousands of deals over the course of 2024, a figure that confirms how active the small and medium-sized business segment has become (TTR Data, 2024). A structural factor adds to this: a significant share of Spanish family businesses does not survive the generational handover, according to the Instituto de la Empresa Familiar (the Spanish family business institute), which makes a sale or an orderly transfer an increasingly common strategic route for founding shareholders (Instituto de la Empresa Familiar, 2024).

This guide walks step by step through the full process of selling a company in Spain in 2026: how to prepare it, how to value it, what role due diligence plays, how the information memorandum is structured, where to find buyers and how to close the share purchase agreement with legal certainty.

When is the right time to sell a company?

There is no single optimal moment, but there are signals that the time has come to consider a sale. The most frequent driver among Spanish industrial SMEs is succession: the owner is approaching retirement and no family member is willing or ready to take over. Other common reasons are the need for a financially stronger partner in order to scale, founder fatigue, an unsolicited offer from a competitor or a fund, or the wish to diversify personal wealth that sits almost entirely in a single asset.

The key is to understand that the best moment to sell is not the company's worst moment. A business sells better when it is growing, when its accounts are in order and when the buyer can see room to grow. Selling from a position of weakness, with falling sales, cash flow pressure or total dependence on the founder, sharply reduces both the value and the number of interested candidates.

Step 1: preparing the company for sale

Preparation has the greatest impact on the final outcome and, paradoxically, it is the stage most often neglected. Ideally it starts 12 to 24 months before the company goes to market, because many of the improvements that lift value, such as reducing dependence on the founder, spreading the client base or tidying up the accounts, need time to take hold.

The priorities at this stage are:

• Put the financial information in order: audited annual accounts or, at the very least, reviewed ones; bank reconciliations up to date; and a normalised EBITDA that adjusts for one-off costs, above-market shareholder remuneration and related-party transactions.
• Reduce dependence on the founder: a business where everything runs through one person is worth less. Documenting processes and building a professional management team raises both appeal and price.
• Spread the client base: heavy concentration in a single client is one of the main reasons buyers discount the price.
• Clear up contingencies: pending litigation, open tax inspections or contracts with change-of-control clauses should be identified and, wherever possible, resolved before they surface in the buyer's due diligence.
• Optimise tax and incentives: companies that already claim R&D&I tax deductions and other Spanish incentives show better metrics, which translates into a higher valuation.

Step 2: valuing the company

Before going to market you need an objective reference point for value. A business valuation does not set the final price, because the negotiation with the buyer does that, but it sets the starting point and avoids two opposite mistakes: asking for an unreachable price that scares candidates away, or selling cheaply out of ignorance.

In Spanish SMEs the most widely used method is comparable multiples, usually applied to EBITDA: value is estimated by multiplying normalised EBITDA by a sector multiple. For more sophisticated deals or companies with predictable cash flows, discounted cash flow (DCF) is used, and for asset-heavy businesses, adjusted net asset value. Good professional practice is to apply at least two methods and compare the results, so that you end up with a negotiating range rather than a single figure.

If you want to go deeper into the methods, how they are applied and the factors that raise or lower value the most, we have written a dedicated guide on what my company is worth and the valuation methods.

Step 3: the information memorandum and the teaser

With the company prepared and valued, it is time to draw up the documentation that will be shown to potential buyers. There are two complementary documents:

• The teaser: a short, anonymous document of one or two pages that summarises the opportunity without revealing the identity of the company. It is used to spark the interest of candidates before they sign a confidentiality agreement.
• The information memorandum (the cuaderno de venta): a detailed document, handed over only after a non-disclosure agreement (NDA) is signed, describing the business in depth: history, business model, team, clients, historical accounts and forecasts, assets and the reasons for the sale.

A well-built information memorandum conveys professionalism, anticipates the buyer's questions and speeds up the process. A careless document does the opposite: it creates distrust and opens the door to downward renegotiation.

Step 4: finding buyers

There are essentially two buyer profiles. Strategic buyers are companies in the same sector or in complementary ones that want to grow, absorb capabilities or remove a competitor; they tend to pay more because they capture synergies. Financial buyers, such as private equity funds, search funds or family offices, aim to earn a return on the investment and bring professional management in.

The search calls for discretion: filtering conversations so that employees, clients or competitors are not alerted too early is one of the main reasons to lean on an M&A adviser. The goal is not to find one buyer but to generate several candidates in parallel, because competition between interested parties is what improves the terms for the seller.

Discretion and competition between candidates are what move the final price. See how we run a buyer search confidentially and professionally.

Step 5: due diligence

Once a buyer submits an indicative offer and a letter of intent (LOI) is signed, due diligence begins: the detailed review the buyer carries out to verify that the information is accurate before completion. It covers financial, tax, employment, legal and corporate matters and, increasingly, environmental and compliance ones too.

This is the stage where most deals fall apart. Any hidden contingency, such as an unprovisioned tax debt, an irregular employment contract or an undeclared dispute, can cut the price, add further guarantees to the contract or derail the deal entirely. That is why the preparation in Step 1 matters so much: a company with its information in order and its contingencies resolved comes through due diligence solidly and keeps its negotiating power.

To understand in detail which documents are reviewed and how to get ahead of them, read our guide on what due diligence is and how to prepare for it.

Step 6: negotiation and closing the contract

Once due diligence is over, the parties negotiate and sign the contract for the sale and purchase of shares or quotas, known as the SPA (Share Purchase Agreement). This is the document that gives effect to the deal and where the seller's greatest legal risks are concentrated.

The key points negotiated at this stage are:

• The price and how it is paid: cash on completion, deferred, or linked to future results through an earn-out clause.
• The representations and warranties: the seller's statements about the condition of the company, which create liability if they turn out to be wrong.
• The indemnity regime: time limits and caps on the seller's liability, plus security such as escrow accounts or bank guarantees.
• Non-compete and stay-on covenants: sellers are often asked not to compete for a set period and, in some cases, to remain in the company to secure the transition.

The transfer of quotas in a Spanish limited company is subject to formal requirements and registration under the Ley de Sociedades de Capital (Royal Legislative Decree 1/2010, the Spanish companies act), and the deal has significant tax consequences for the seller: the capital gain is taxed under IRPF (Spanish personal income tax) or under the Impuesto sobre Sociedades (Spanish corporate income tax), depending on who the seller is. Legal and tax advice at this stage is not a luxury but protection against liabilities that can surface years after completion.

Frequently asked questions about selling a company

How long does it take to sell a company in Spain?

Selling an SME usually takes 6 to 12 months from the start of the buyer search to signing, although timescales vary widely with size, sector and complexity. On top of that comes the preparation phase, which ideally starts 12 to 24 months earlier. Well-prepared deals tend to close faster and on better terms.

How much does it cost to sell a company?

The main cost is the M&A adviser's fee, which usually combines a fixed retainer with a success fee calculated as a percentage of the sale price. On top of that come the legal costs of the contract, the tax due on the deal and, where relevant, an independent valuation. It may look expensive, but good advice tends to raise the final price and reduce risk by far more than it costs.

What taxes do you pay when selling a company?

The seller is taxed on the capital gain, that is, on the difference between the sale price and the acquisition value of the shares. If the seller is an individual, that gain goes into the savings base of IRPF (Spanish personal income tax); if the seller is a company, it is taxed under the Impuesto sobre Sociedades, where the exemption for dividends and capital gains on shareholdings set out in article 21 of the Spanish corporate income tax act may apply if the legal requirements are met. Planning the tax position early makes a decisive difference to the final bill.

Do I need to hire an adviser to sell my company?

It is not compulsory, but it is strongly recommended. Selling a company is a technical process, heavy on negotiation and carrying real legal risk. An M&A adviser brings access to buyers, the ability to create competition between candidates, experience in negotiating price and warranties, and the discretion needed to avoid damaging the business along the way. Meanwhile the owner can stay focused on running the company, which is essential so that results do not slip at the very moment they are under most scrutiny.

Can I sell only part of my company?

Yes. Not every deal involves selling 100 %. It is common to sell a majority stake while keeping a minority, to bring in a financial partner in order to grow, or to structure a gradual exit in which the founder stays on for a while. The best structure depends on the owner's objectives, their personal wealth position and the buyer's profile.

Conclusion: the next step

Selling a company successfully is not a matter of luck but of method, preparation and professional support. Every stage, from preparation and valuation to the information memorandum, the buyer search, due diligence and closing, shapes the outcome of the next one, and mistakes made early are paid for dearly at the end. An owner who arrives at the market with the company in order, a rigorous valuation and an adviser alongside starts with a decisive advantage.
