Mergers and Acquisitions: Meaning, types and how they work

15 December 2024

Mergers and acquisitions (M&As) are strategies that enable companies to grow. Merging with another company operating in the same business sector can increase market share and turnover. Acquisitions are different in that a company might buy an established business working in an industry unlike that of the purchaser.

These transactions can produce significant benefits for both parties; however, mergers and acquisitions also have the potential to be problematic, such as in cases where businesses may be impacted by regulatory issues or cultural clashes. Read on to discover more about challenges like these and how you can mitigate against them.

This guide provides an overview of mergers and acquisitions, including their different types, benefits and the challenges they present.

What are Mergers and Acquisitions?

Mergers and acquisitions are fundamentally different in that two companies often merge to create a larger business – growth in any business is a positive thing. Whereas, acquisitions occur when one company purchases another, usually when a large business purchases a smaller one. The total value of merger and acquisition deals globally was $3.7 trillion In 2019.

A merger or acquisition typically occurs following the purchase of assets, equity shares or by combining operational structures. These business deals are often motivated by a need to reduce competition, gain entry into new markets or acquire valuable assets and technology.


Difference between Mergers and Acquisitions

Let’s explore in greater depth the differences between mergers and acquisitions. The terms are sometimes used interchangeably, but there are some significant differences between the two. For example:

Horizontal mergers

Horizontal mergers occur when two companies in the same or similar industries combine. For example, the merger between Disney and 21st Century Fox was horizontal. Such mergers allow companies to reduce competition, increase market share, cut costs, increase diversification, share complementary resources and skills, and realise economies of scale.

However, horizontal mergers can be problematic. Sometimes the process struggles to merge the two corporate cultures and difficulties arise in building working relationships because of variations in management styles. It can also face increased regulatory scrutiny, especially if the merger creates a company that is considered a monopoly.

Vertical mergers

In a vertical merger, two companies in the same industry but at different stages of the supply chain are merged, such as a manufacturer and a supplier. It aims to streamline operations and reduce costs. For example, when Apple acquired AuthenTec, the firm that makes touch-ID sensor technology, it took control of the production and distribution of the technology.

Vertical mergers enable companies to reduce operating costs, increase profits, improve quality control and improve the flow of information across the supply chain. However, a vertical merger can face integration challenges, limit flexibility and cause disruption to existing supplier relationships. Also, if synergies are overestimated, it can lead to higher costs.

Conglomerate acquisitions

These are mergers between companies in very different industries that enable them to diversify their business. For instance, Microsoft acquired the professional networking site LinkedIn. A conglomerate acquisition offers many benefits, including increasing market power, providing access to new expertise and technologies, and diversifying products, services, and markets.

However, this type of acquisition can create a lack of constructive collaboration between the companies, reduce efficiency, shift focus and resources away from the firm’s core business or result in a culture clash.

Market extension acquisitions

When a company acquires another in a different geographic location it is termed a market extension acquisition. The acquisition allows a company to increase its customer base by expanding the reach of its market.

When PepsiCo acquired the South African company Pioneer Foods in 2019, it extended its product offerings, grew its distribution network and market presence in Africa. These market extension acquisitions often face challenges when integrating the different cultures and business styles of companies. Dealing with new regulatory barriers can also be a problem.

Congeneric acquisitions

Congeneric acquisitions are when the acquiring (purchasing) company and the acquired (target) company are not direct competitors but sell to the same customers. For example, PepsiCo’s merger with Gatorade and Tropicana Juice was a congeneric acquisition.

These companies often share similar distribution channels, production processes, technology or marketing. This type of acquisition can enable the purchasing company to increase its market share and expand product lines quickly. However, it can mean that because they are in the same industry and targeting the same clients, the scope for diversification is very limited.

Management acquisitions (MBOs)

Management acquisitions, also known as management buyouts (MBOs), are when a company’s management team or an individual from the team purchases the business from its owners. They purchase everything related to the business.

In 2013, the founder of Dell, Michael Dell, having secured backing from an equity firm, led an MBO to take the company private. This type of acquisition offers greater rewards and control of the business. It is typically funded with borrowed capital; however, this type of acquisition comes with significant risk and its success is not guaranteed.


Advantages and disadvantages of Mergers and Acquisitions

Significant benefits can be realised through mergers and acquisitions; however, some drawbacks can become apparent when companies merge or acquire another business that were not obvious during the negotiations. They can have an impact on whether a deal is an eventual complete success.

Advantages

  • Market expansion: Companies can gain access to new markets, consolidate resources, access a new customer base and diversify their business offerings.
  • Economies of scale: Expanding a business by acquiring another company can improve cost efficiency by allowing the negotiation of bulk orders at lower unit prices and increases a company’s purchasing power overall.
  • Increased revenue and market share: Merging or acquiring another company enables businesses to enjoy a greater market share, resulting in increased revenues.
  • Diversification: Mergers and acquisitions enable companies to diversify their service or product offerings, reducing the risk of depending on specific markets and increasing revenue.
  • Access to new technology and expertise: A merger or acquisition can help boost research and development capabilities and provide access to new technologies, intellectual property and valuable expertise.
  • Tax benefits: Mergers can offer certain tax incentives, such as using the acquired company’s losses to reduce future taxes. Merger companies can also save on taxes by sharing losses and gaining tax allowances for new assets.
  • Enhanced financial capacity: When companies merge or acquire another, they can pool their financial resources or benefit from improved access to financing and investment.

Disadvantages

  • Integration challenges: Combining systems, processes and staff can disrupt operations and harm productivity and customer service.
  • High costs: Mergers and acquisitions can be expensive, incurring considerable costs that may strain resources and impact financial stability.
  • Regulatory risks: There can be increased regulatory scrutiny following a merger or acquisition, and international trade, in particular, can involve levels of regulation not previously encountered. Regulatory approval can sometimes be harder and more complex to secure at home and abroad.
  • Culture clashes: Integrating two companies can cause culture clashes that create a negative working environment post-merger.
  • Increased debt: Mergers and acquisitions are not cheap and can significantly increase a company’s debt.
  • Employee redundancies: A merger or acquisition can lead to redundancies or key employees leaving if they are concerned about the direction of the business or unhappy with restructuring.
  • Risk of overestimation: If a company has overestimated the benefits of a merger or acquisition, it can cause a long-term negative financial outcome.
