Mergers and Demergers of Companies in Uruguay: Process and Requirements

SA
Sociedades Anónimas Team

Mergers and demergers of companies in Uruguay are legal tools used to reorganise corporate structures, optimise operations and adapt businesses to new strategies. Both a merger and a demerger (escisión) formally change a company’s structure, with legal, accounting and tax effects that must be analysed carefully before going ahead.

What Is a Merger?

A merger of companies in Uruguay consists of combining two or more companies into a single business structure.

In some cases, one company absorbs another; in others, several companies join to create a new entity. This mechanism is often used to consolidate operations, reduce administrative costs or expand into certain markets.

The advantages of a merger can include operational improvements, simpler structures and more efficient corporate management.

How to Merge Two Companies in Uruguay

Merging two companies in Uruguay requires a combination of legal, corporate and registration steps.

In general terms, the transaction usually includes:

  • A legal and accounting review of both companies
  • Agreement between partners or shareholders
  • Drafting the merger documents (merger agreement and special balance sheets)
  • Formalisation by public deed
  • Legal publications and registrations

These steps summarise the basic procedure, although each case may have its own particularities depending on the company type and the sector.

Legal Requirements for a Merger

The legal requirements for a merger of companies in Uruguay, governed by the Commercial Companies Law No. 16,060, vary depending on the structure of the companies involved.

Formal approval by partners or shareholders, merger agreements and compliance with mandatory publications and registrations are generally required. Creditors’ rights must also be respected during the process.

For corporations, a merger of SAs in Uruguay usually involves board resolutions and shareholders’ meetings with the majorities required by law and the bylaws.

For SRLs, the merger must be formalised by public deed with the corresponding registry update.

Merger by Absorption in Uruguay

One of the most common forms is the merger by absorption.

In this arrangement, one company takes over the assets and liabilities of another, which ceases to exist as a separate legal entity.

It is often used in business groups or internal reorganisations aimed at simplifying corporate structures.

Tax and Regulatory Aspects of a Merger

The tax implications of a merger with DGI are central to any corporate reorganisation.

Depending on how the transaction is structured, there may be tax effects related to the transfer of assets, tax losses or the continuity of tax obligations. Uruguayan rules provide special treatment for certain reorganisations, so they should be analysed with the accountant in advance.

In certain regulated sectors, especially financial or supervised activities, prior approval from the BCU may be needed before completing the merger.

It is also important to consider the costs of a merger, which can include legal fees, notary costs, publications and registry fees.

What Is a Demerger?

A demerger (escisión) of companies in Uruguay works the opposite way to a merger. Instead of combining companies, it divides one company into two or more independent structures.

It is often used to separate business lines, reorganise assets or reduce risks within a business group.

How to Demerge a Company in Uruguay

Demerging a company in Uruguay usually starts by defining which assets, contracts or business units will be transferred.

It then requires corporate approval, legal formalisation and registration with the relevant bodies.

The public deed of demerger is one of the essential steps for the reorganisation to be legally valid.

Types of Demerger

There are different types of demerger depending on the purpose of the reorganisation.

A partial demerger occurs when only part of the assets is transferred to another company, while the original company continues to exist.

A total demerger, by contrast, involves dividing the whole company, which is dissolved and distributes its assets among new entities.

A demerger to separate assets is especially common in asset-holding structures, holdings or companies with several operating units.

Demergers of SAs and SRLs

The legal requirements for demerging an SA include specific corporate procedures, such as shareholder approval and registry formalities.

The demerger process for an SRL follows a similar logic, adapted to the rules for limited liability companies.

In both cases, it is essential to analyse the legal and tax consequences of the transaction beforehand.

Merger vs. Demerger

The main difference between a merger and a demerger is structural.

A merger combines companies into one entity, while a demerger divides a company into several independent structures.

Both are part of corporate reorganisation processes but are used for different purposes depending on each company’s strategic needs.

Conclusion

Mergers and demergers of companies in Uruguay are key mechanisms for reorganising corporate structures and adapting businesses to new challenges.

Understanding how a merger works, what the requirements are and how a demerger operates allows strategic decisions to be made with greater confidence.

Whether to consolidate operations, separate assets or reorganise business groups, proper legal, accounting and tax advice is essential for a successful process.
