Buying a Portuguese Company: Share Deal vs Asset Deal

Buying an existing business in Portugal can be structured in very different ways.

The first strategic decision is often whether you are buying:

  • the company itself through its shares or quotas; or
  • selected assets, contracts and business operations from the company.

These are commonly described as a share deal and an asset deal.

The commercial result can look similar from the outside. Legally, the two structures are very different.

What happens in a share deal?

In a share deal, the buyer acquires an ownership participation in the existing company.

For a Portuguese Lda, this normally means buying quotas.

The company itself remains the same legal entity.

That means the company normally continues to own its:

  • bank accounts;
  • equipment;
  • real estate;
  • intellectual property;
  • receivables;
  • contracts;
  • licences;
  • employees.

The company also continues to carry its existing liabilities and history.

The buyer is not buying only the good assets. The buyer is acquiring an ownership position in the company that already owns the assets and owes the liabilities.

Why due diligence matters more in a share deal

Because the legal entity remains intact, historic risk stays inside it.

Potential issues can include:

  • unpaid tax;
  • litigation;
  • employment claims;
  • guarantees;
  • shareholder loans;
  • regulatory problems;
  • data-protection issues;
  • IP ownership gaps;
  • unfavourable contracts;
  • undisclosed debts.

That is why legal and financial due diligence is normally central to a company acquisition.

The buyer should understand what is inside the company before taking ownership.

How is an Lda quota transferred?

Portuguese company law requires an inter vivos quota transfer to be in writing.

Company consent can also be required before the transfer becomes effective toward the company, subject to statutory exceptions and the company articles.

The articles can modify important parts of the default transfer framework.

So the acquisition process should include a review of:

  • current articles;
  • quota ownership;
  • consent rules;
  • shareholder agreement;
  • current commercial registration.

Do not sign a purchase agreement assuming corporate consent is only a post-closing administrative step.

What is an asset deal?

In an asset deal, the buyer does not acquire the seller company itself.

Instead, the buyer acquires identified assets or an operating business from it.

Depending on the transaction, this can include:

  • equipment;
  • inventory;
  • customer relationships;
  • IP;
  • domain names;
  • business name rights;
  • real estate;
  • leases;
  • contracts;
  • receivables;
  • goodwill;
  • an operating establishment.

The seller company can continue to exist after the sale.

Why an asset deal can give more control over what is acquired

An asset deal can allow the buyer to define the transaction perimeter more precisely.

The buyer can identify which assets are intended to transfer.

But that does not mean every unwanted liability can automatically be left behind.

Some rights and obligations transfer by law or require third-party consent.

Every asset category needs its own analysis.

Contracts do not necessarily transfer automatically

A commercial contract is not simply a physical asset.

Portuguese contract law generally requires the other contracting party's consent to transfer a contractual position in a reciprocal contract.

The consent can sometimes be given in advance.

The contract itself can also contain:

  • assignment rules;
  • change-of-control clauses;
  • termination rights;
  • consent requirements.

A buyer should therefore review key contracts before assuming they will move with the business.

What happens to employees in an asset deal?

This is a particularly important distinction.

Portuguese Labour Code rules on transfer of an undertaking, establishment or economic unit can transfer the employer position to the buyer.

Where the statutory transfer rules apply, affected employees keep rights such as:

  • remuneration;
  • seniority;
  • professional category;
  • contractual functions;
  • acquired social benefits.

So an asset deal cannot be structured on the simplistic assumption that the buyer takes the operating business but chooses freely which attached employees exist.

Employment due diligence is essential.

Share deal and employees

In a pure share acquisition, the employing company normally remains the same legal entity.

The shareholder changes.

The employer does not automatically change simply because the quotas change hands.

But key employees and management still matter commercially.

Their contracts can contain bonus, retention, non-compete, termination or change-of-control provisions.

Licences and permits

In a share deal, a licence held by the company can remain with the same legal entity.

But change of ownership can still trigger:

  • notifications;
  • regulator approval;
  • fit-and-proper review;
  • bank KYC;
  • beneficial-owner updates.

In an asset deal, a licence may not be transferable at all.

Do not assume the buyer automatically receives every licence needed to operate the business.

Real estate and leases

If the company owns Portuguese real estate, a share acquisition does not itself transfer title to the real estate out of the company.

The company remains owner.

In an asset deal, a direct real-estate acquisition is a separate property transaction with its own legal, registry and tax consequences.

For leased premises, review whether the lease permits transfer or change of control and whether landlord consent is required.

Tax structure

Share deals and asset deals can have materially different tax consequences for:

  • seller;
  • buyer;
  • company;
  • assets;
  • goodwill;
  • future deductions.

Legal structuring should therefore be coordinated with qualified Portuguese tax advice before the transaction structure is fixed.

This guide does not replace transaction-specific tax analysis.

Shareholder loans

Founder loans and other shareholder financing need separate treatment.

Buying all quotas does not automatically mean that the seller's loan to the company has been transferred or repaid.

The acquisition documents should state whether shareholder debt is:

  • repaid before closing;
  • assigned;
  • capitalised;
  • left outstanding;
  • included in price mechanics.

What happens to management?

A quota acquisition does not automatically change every gerente.

The transaction should decide whether existing managers:

  • remain;
  • resign at closing;
  • are removed;
  • are replaced.

Management changes need separate corporate documentation and registration.

Beneficial ownership after acquisition

If ownership or control changes, the RCBE information may need updating.

Current official guidance requires relevant RCBE changes to be updated within 30 days from the event causing the change.

Do not stop the closing checklist at the quota-transfer registry filing.

Share deal or asset deal: which is better?

There is no universal answer.

A share deal can be attractive where the buyer wants continuity of:

  • contracts;
  • licences;
  • employees;
  • assets;
  • business identity.

An asset deal can be attractive where the buyer wants a defined transaction perimeter.

The decision can depend on:

  • hidden-liability risk;
  • tax;
  • employee transfer;
  • contracts;
  • licences;
  • financing;
  • seller preference;
  • operational continuity.

The transaction structure should be chosen after preliminary due diligence, not before understanding the business.

A practical acquisition sequence

1. Define what you actually want to buy

Company ownership or identified assets/business?

2. Review public company records

Ownership, gerentes, articles, capital and filings.

3. Run legal and financial due diligence

Identify liabilities and required consents.

4. Choose share or asset structure

Coordinate legal, tax and operational consequences.

5. Agree price mechanics

Including debt and shareholder loans.

6. Negotiate acquisition documents

SPA, asset purchase agreement and ancillary documents.

7. Satisfy conditions precedent

Corporate, contractual, regulatory and financing.

8. Close

Payment and signed transfer documents.

9. Complete post-closing registrations

Commercial registry, RCBE and practical control transition.

Common mistakes

Choosing a share deal only because it seems simpler

Historic liabilities remain in the company.

Choosing an asset deal and assuming contracts automatically follow

They may require consent.

Ignoring employee-transfer rules

An operating business can bring employment obligations with it.

Forgetting shareholder loans

Ownership and company debt to the seller are different matters.

Treating closing and registration as the same event

The transaction documents and public registry steps need coordination.

Frequently asked questions

Is buying quotas the same as buying company assets?

No. You acquire ownership in the company. The company remains owner of its assets.

Can an asset buyer leave all liabilities behind?

Not automatically. Some obligations can transfer by law and contracts/operations need specific analysis.

Do employees transfer in an asset deal?

They can where the transaction qualifies as transfer of an undertaking, establishment or economic unit under Portuguese labour law.

Does the company need to approve a quota sale?

Often, subject to statutory exceptions and the company articles.

Is due diligence necessary for a small Lda?

The scope can be proportionate, but historic company risk does not disappear because the company is small.

Does RCBE need updating after a share deal?

If the declared beneficial-ownership information changes, current guidance requires an update within 30 days.
