Difference Between Mergers and Acquisitions

Merger refers to consolidating two or more business entities to form one joint entity with the new management structure, ownership, and name, capitalizing on its competitive advantage and synergies. In contrast, the acquisition is the case where one financially strong entity takes over or acquires a less financially strong business entity by acquiring all shares or shares with a value greater than 50% of its total shares.

Mergers vs Acquisitions

Both are corporate strategies aimed at increasing the present capabilities of a company. Sometimes both terms are misunderstood as merely adjoining two or more companies, but these terms are quite different. Various key aspects form the basis of differences between them, for example, purpose, objectives, and mutual agreement. Understanding them can help eliminate any kind of confusion. 

Key Takeaways

  • Mergers refer to agreements between 2 or more companies to form a combined entity with a new name, financial structure, and management structure.
  • On the other hand, an acquisition involves the takeover of a smaller entity by a larger company via the purchase of the majority of the shares.
  • No fresh issue of shares takes place in the case of acquisitions, unlike mergers.
  • Mergers involve mutual agreement of the companies forming the combined entity. In contrast, an acquisition may involve a mutual agreement.
  • Generally, mergers are more complex than acquisitions in terms of financial and legal standpoints.

Reasons For Mergers And Acquisitions (M&As)

Let us look at some popular reasons why businesses may decide to participate in M&As. 

  • Diversification: Companies often engage in M&As to diversify their services, market segments, or product lines. This diversification helps them in minimizing risk. 
  • Economies Of Scale: Mergers can allow companies to reduce costs by utilizing the same resources. This raises the operational efficiency and production capacity. 
  • Market Expansion: Organizations may decide to acquire or merge with another company to expand market operations. 
  • Synergy Development: These deals aid in synergy development as companies can use complementary sets of capabilities and resources to optimize resource allocation and enhance efficiency. 
  • Tax Benefits: A few companies acquire other organizations or merge with them to get tax advantages. For example, after completing a merger, organizations can lower the tax payable because of the spreading of financial losses. 
  • Market Share: Acquisitions, as well as mergers, allow companies to improve their market share. This is because, as a result of these deals, competition is reduced, and companies can improve their position within the industry. 
  • Access To New Expertise Or Technology: Another key motivation can be the ability to access new intellectual property or improved technology following the acquisition or merger.
  • Improvement In Brand Value: Mergers and acquisitions can have a positive impact on the goodwill and brand value of both companies.       

Key Differences

  • One of the key differences is that the merger is when two or more companies agree to come together and form a new company; an acquisition is when a financially strong company takes over a less financially strong company by buying more than 50% of its shares.
  • The merger is a strategic decision made after careful discussion and planning between the companies going to be merged. Hence, there are fewer chances of a chaotic atmosphere after merging. The acquisition is also a strategic decision, but the decision is not mutual in most cases. Hence, there is a lot of hostility and chaos after an acquisition has been made.
  • The power difference between the acquired and acquiring companies is huge. Companies that are merged usually consider each other of equal stature, and hence they help each other out to create a synergy. In the case of an acquisition, the company that acquires it imposes its will on the acquired company, and the acquired company is stripped of its freedom and decision-making.
  •  Since the merger requires a whole new company to be formed, it needs many legal formalities and procedures to be followed. The acquisition doesn’t have many legal formalities and paperwork to be filled compared to the merger.

ObjectivesThe main goals of a merger are cost reduction, taking advantage of economies of scale, and creating synergies. The main objective of an acquisition is to gain a strategic advantage, for example, decreased competition in the market. 
Mutual Agreement A merger results from the mutual agreement between the involved parties. An acquisition may not involve mutual agreement. One company can take over another organization without the latter’s consent.

Conclusion

We may decide that a merger is always better than an acquisition when comparing mergers and acquisitions. But just like how each coin has two sides, both have their strengths and weaknesses.

Companies make these decisions based on their situation and the resultant discussions that they have had with the other companies. So, it is wise for companies to carefully analyze the position that they are in and take the strategic decision that better suits the scenario and demands.
