Why M&A Happens?

Why M&A Happens

Every single day, hundreds and thousands of businesses are starting up, growing, and competing in the market. And every one of them has the same end goal — to maximise profits, to build their reputation, to capture market share, and to create real value. That is why businesses exist.

M&A is simply a more efficient way of making that happen.

When we talk about M&A — mergers and acquisitions — we are talking about companies joining forces to become one bigger, better, and more powerful entity. Think of it like a crossword puzzle. Two pieces that are right for each other come together, and suddenly the whole picture makes sense. Alone, they were good. Together, they just work.

A simple example to start with

Take Disney and Pixar. Both were brilliant companies on their own. Disney had the legacy, the distribution, and the brand. Pixar had the technology and the storytelling genius. But after Disney acquired Pixar in 2006, something changed. Together they created Up, WALL-E, Brave, Toy Story 3 — movies that neither company would likely have made alone, at least not at that level. That is what M&A can do at its best. Two strong companies combine, and what they create together is stronger than what either could have built separately.

So why does M&A actually happen?

There are several reasons — commercial, strategic, and sometimes out of necessity. Let's go through the main ones.

1. To create synergies

The word you will hear most often in any M&A discussion is synergies. Synergies are the value that is created by combining two businesses — value that neither of them could have created on their own.

There are two types:

Revenue synergies — the combined entity can now sell more. They can cross-sell to each other's customers, enter new geographies, or tap into niche markets that neither had access to before. The revenue potential simply gets bigger.

Cost synergies — the combined entity can now spend less. They eliminate duplicate functions, consolidate supply chains, and achieve economies of scale that were not possible when they were operating separately.

A strong real-world example of this is Tata Steel's acquisition of Corus in 2007. Both were strong companies independently. But what happened when they came together was significant — Corus gave Tata Steel access to European markets and high-value steel products. Tata, in return, gave Corus access to low-cost Indian raw materials. The combined entity was stronger than either could have been alone.

That is synergy in action.

2. To consolidate the market

Another major reason companies pursue M&A is to consolidate their position in the market. When two companies in the same industry combine, competition reduces and market share increases. You are not just growing your own business — you are absorbing a competitor and becoming more dominant in the process.

The Vodafone-Idea merger in 2018 is a good example of this. When Reliance Jio entered the Indian telecom market, it came in aggressively — cheap data, free calls, and a massive infrastructure investment behind it. For existing players like Vodafone and Idea, competing individually became increasingly difficult.

So they merged. The combined entity, Vi, had a significantly larger subscriber base, better network coverage, and stronger bargaining power with vendors. The merger was a direct response to competitive pressure — two companies realising they were stronger together than they were fighting the same battle separately.

3. To enter a new market faster

Sometimes a company wants to expand into a new geography or a new sector, but building that presence from scratch would take years. You would need to understand the local market, build a customer base, hire the right people, and establish trust — all of which takes time and money. Acquiring a company that already operates there is faster, cheaper, and lower risk. You are not starting from zero. You are buying an existing customer base, an existing team, and an existing operational setup.

Walmart's acquisition of Flipkart in 2018 is one of the best examples of this. Walmart is one of the largest retailers in the world. But India's e-commerce market was something it had not cracked. Rather than spending years trying to build its own platform in India from scratch — against established players like Amazon and Flipkart — Walmart simply acquired Flipkart for approximately $16 billion. Overnight, it had a leading e-commerce platform, an established logistics network, millions of customers, and a deep understanding of the Indian consumer. That is what entering a new market through acquisition looks like.

4. To rescue a distressed business

Not every M&A deal happens from a position of strength. Sometimes a company is not doing well on its own — it is financially stressed, struggling with debt, or simply not generating the profits it should. In those situations, a larger and more stable company may step in and acquire it.

Once that struggling company becomes part of a bigger, better-resourced entity, things can change quickly. It gets access to capital, to infrastructure, to a larger customer base — things it could not build on its own. The acquirer, on the other hand, often gets a valuable asset at a significant discount. Both sides can benefit.

A well-known Indian example of this is Tata Motors' acquisition of Jaguar Land Rover from Ford in 2008. Ford had acquired JLR years earlier but was struggling to make the business profitable. By the time Tata stepped in, JLR was available at a price that reflected its distress. What happened next is now business school material — Tata turned JLR around, invested in new models, and built it into one of the most profitable parts of the Tata group. A distressed acquisition, executed well, can create enormous value.

Mergers vs. Acquisitions — what is the difference?

Since we are on this topic, it is worth quickly clarifying the two terms — because they are used together so often that the difference can get blurry.

A merger is when two companies come together and become one new entity. Both give up their individual existence to form something new together. Think of it as two rivers joining and becoming one.

An acquisition is when a larger company takes over a smaller one. The smaller company becomes part of the bigger company — its operations, its people, its assets all come under the acquirer's control. The acquired company does not disappear necessarily, but the acquiring company is now firmly in the driver's seat.

Both achieve the same broad goal — combining forces to create something stronger. The difference is in the structure and the dynamics of the deal.

The bottom line

M&A happens because growth has a ceiling when you are working alone. At some point, the fastest way to get bigger, stronger, and more competitive is not to build everything yourself — it is to join forces with someone who already has what you need. Whether it is synergies, market share, a new geography, or a turnaround opportunity — M&A is how businesses accelerate what would otherwise take years.

In the next chapter, we go deeper into what M&A actually looks like — the different types of mergers, the different types of acquisitions, and how each one works.
