Mergers and acquisitions (M&A) are key strategic tools for business growth, diversification, and consolidation in increasingly competitive markets. Whether through the full integration of two companies or the acquisition of a business to expand market reach, these transactions enable organizations to leverage synergies, optimize resources, and strengthen their competitive position.
Today, having specialized M&A legal and strategic advice is essential to ensure that each step is taken in full compliance with current regulations while minimizing associated risks. In this article, we will explain in detail what mergers and acquisitions are, their types, key differences, and benefits, as well as the legal and tax aspects every company should consider before engaging in such a transaction.

What Is a Business Merger?
A business merger is a form of corporate reorganization in which two or more companies combine to form a single legal entity. This operation can take two main forms: a merger by absorption (where one company absorbs another) or a merger by creation (where a new company is formed to replace the original ones).
The main objective of a merger is to enhance operational efficiency and achieve strategic synergies that allow companies to improve their market competitiveness. Additional benefits include cost reduction, resource optimization, and commercial expansion.
In the M&A context, mergers are a critical tool for corporate restructuring processes and often involve fiscal, labor, and legal implications that require specialized legal guidance.
What Is an Acquisition?
A business acquisition is a type of corporate transaction in which one company purchases all or part of another, gaining direct control over its assets, liabilities, and operations. Unlike mergers, in an acquisition, the acquiring company retains its legal identity, while the target company may either maintain or lose its legal status, depending on the terms of the deal.
Strategic acquisitions are key tools in corporate growth and business expansion. Common objectives include entering new markets, acquiring innovative technologies, attracting top talent, or strengthening presence in specific industries.
These operations fall within the broader category of mergers and acquisitions (M&A) and often involve legal, tax, and regulatory complexities. For this reason, they require thorough legal due diligence and specialized advisory services to minimize risks and maximize transaction value.
Differences Between a Merger and an Acquisition
Mergers and acquisitions are both common forms of corporate reorganization, but they differ significantly in structure, legal implications, and strategic impact. Below are the key differences:
- Relationship between the parties: In a merger, both companies act as equals seeking a ; in an acquisition, one entity takes a dominant position, exercising control over the other.
- Impact on legal identity: A merger may result in the creation of a new company or the continuation of one existing entity; in an acquisition, the acquiring firm retains its legal identity and absorbs, either fully or partially, the target company.
- Internal and external perception: Mergers are usually presented as strategic, collaborative decisions, whereas acquisitions—especially hostile ones—may lead to resistance from employees or shareholders.
- Distribution of corporate power: In a merger, decision-making power is redistributed among the leadership of both companies; in an acquisition, control largely remains with the acquiring party.
- Nature of the process: Mergers typically involve balanced negotiations between equals, while acquisitions may be either friendly or hostile, depending on shareholder participation and the level of approval from the target company’s management.
Types of Mergers and Acquisitions
Mergers and acquisitions (M&A) can be classified based on the relationship between the companies involved and the nature of the integration. This classification helps define the appropriate corporate strategy and anticipate the financial, operational, and legal implications of each type of transaction.
Horizontal Merger
A horizontal merger occurs between direct competitors operating in the same sector or market. Its main goal is to consolidate market share by combining resources and capabilities, which strengthens market position and negotiation power with suppliers and distributors. It also enables operational cost reduction through economies of scale and increased efficiency. However, regulatory approval may be required to avoid antitrust violations.
Vertical Merger
A vertical merger involves companies within the same supply chain, such as a manufacturer and its supplier or distributor. The purpose is to enhance control over the production process, secure raw material supply, and improve distribution efficiency. Vertical integration helps reduce third-party dependency, optimize logistics, and increase responsiveness to market shifts.
Conglomerate Merger
A conglomerate merger involves companies from unrelated sectors. This strategy is often used to diversify risk and expand the business portfolio, reducing reliance on a single market. It also allows entry into new industries and customer segments while leveraging financial or managerial synergies. However, managing different business models and corporate cultures can be challenging.
Friendly Acquisition
A friendly acquisition takes place when the target company voluntarily agrees to the transaction. The two parties negotiate terms transparently and work together to ensure mutual benefits for shareholders, employees, and customers. This approach facilitates integration, minimizes internal conflict, and ensures a smooth operational and cultural transition.
Hostile Acquisition
A hostile acquisition occurs without the prior approval or consent of the target company’s management. It is typically executed by purchasing a majority stake through the stock market or directly appealing to shareholders. While potentially controversial, it is often pursued when strategic opportunities are blocked by the target’s leadership. This type of acquisition may lead to internal resistance, legal disputes, and reputational challenges.
Corporate Mergers and Acquisitions: Legal and Tax Considerations
Mergers and acquisitions (M&A) are subject to rigorous legal, tax, and regulatory scrutiny. Before finalizing any integration, it is essential to conduct comprehensive legal and financial due diligence to assess risks and ensure the legal security of the transaction.
- Criminal liability of legal entities: Verification of compliance with Article 31 bis of the Spanish Criminal Code and existing corporate criminal compliance programs within the target company.
- Tax audit and contingent liabilities: Evaluation of outstanding tax debts, ongoing audits, tax penalties, or aggressive tax planning structures that could impact the deal or create hidden liabilities.
- Data protection and privacy: Analysis of compliance with the Spanish Data Protection Law (LOPD) and the General Data Protection Regulation (GDPR), especially in cases involving the transfer of sensitive data or customer databases.
- Labor regulations: Consideration of employment obligations, including employee subrogation, collective bargaining agreements, severance payments, and potential inherited labor disputes.
- Corporate and minority shareholder rights: Review of corporate law compliance and legal safeguards for minority shareholders, particularly in cross-border mergers or complex restructuring processes.
Advantages of Mergers and Acquisitions
Corporate mergers and acquisitions are essential tools for business expansion and enhancing market competitiveness. When properly planned and executed, they offer a wide range of strategic benefits that support sustainable growth and increased profitability:
- Access to new markets and segments: Expand geographical presence or enter complementary sectors, diversifying business activity.
- Operational and financial synergies: Integration of processes that leads to operational efficiency and optimized use of shared resources.
- Reduction of structural costs: Elimination of administrative, logistical, or commercial redundancies, improving overall profitability.
- Increased negotiation power: A larger market share strengthens bargaining capacity with suppliers, distributors, and clients.
- Acquisition of talent and know-how: Access to skilled teams and strategic intangible assets such as patents, technologies, or industry-specific expertise.
Merger or Acquisition? Choose the Right Strategy for Your Company
The choice between a merger and a corporate acquisition does not follow a one-size-fits-all formula. It depends on critical variables such as your company’s growth objectives, financial structure, organizational culture, and the competitive landscape. Each corporate restructuring operation carries distinct advantages and challenges that must be carefully evaluated through a comprehensive and professional analysis.
To minimize risks and maximize opportunities, it is essential to have a legal team that understands the entire process — from legal and tax due diligence to contract negotiation and post-deal integration.
