What is M&A

In the previous chapter, we talked about why M&A happens. Before we go any further, let us make sure we are clear on three words that will keep coming up throughout this entire guide.

Synergies — the additional value created when two companies combine that neither could have created on their own. The classic example being Tata Steel and Corus.

Efficiency — doing more with less. When two companies merge, they eliminate duplication, streamline operations, and get more output from the same resources.

Economies of scale — as a business gets bigger, its cost per unit goes down. A combined company can produce more, negotiate better with suppliers, and spread fixed costs across a larger base.

These three concepts are deeply connected. And they are the reason why, when M&A is done right, one plus one does not equal two it equals three. The combined entity is more productive than the sum of its individual parts.

So what exactly is a merger?

A merger is the combination of two or more companies into one single entity. But here is what is important to understand — a merger is not just about adding up assets and liabilities. It is about reorganising two distinct businesses into one unified operation.

The Vodafone-Idea merger is a good example we already touched on. These were two separate telecom companies, both struggling to compete against Jio's aggressive entry into the market. Instead of fighting that battle individually, they chose to combine. The result was Vi — one entity with a larger network, a bigger subscriber base, and better economies of scale than either company had on its own.

In a merger, the companies typically come together as equals. Control is shared or restructured jointly between them. Neither side is simply taking over the other — they are building something new together.

And what is an acquisition?

An acquisition — also called a takeover — is when one company purchases a controlling interest in another. This could mean buying the majority of its shares, or buying substantially all of its assets and liabilities. The key difference from a merger is control. In an acquisition, one company is firmly in the driver's seat. The acquiring company takes control, and the target company either becomes a subsidiary or, in some cases, ceases to exist as an independent entity altogether.

Friendly vs. hostile takeovers

Not all acquisitions happen with both sides agreeing at the table. This is where the distinction between friendly and hostile takeovers becomes relevant.

A friendly takeover is exactly what it sounds like — the target company's board and management agree to the acquisition. Negotiations happen, terms are discussed, and both sides reach a deal they are comfortable with. Most acquisitions you read about are friendly. The Walmart-Flipkart deal we discussed in Chapter 1 is a good example — Flipkart's board agreed to the deal.

A hostile takeover is when the acquiring company goes directly to the shareholders of the target — bypassing the board and management entirely — because the board has refused to agree to the deal. The acquirer essentially says: we want to buy this company whether the management likes it or not, and we are going to make an offer directly to the people who actually own it. Hostile takeovers are more common in listed companies where shares are publicly traded and can be purchased on the open market.

A well-known international example is Elon Musk's acquisition of Twitter in 2022 — which began as a hostile move when Twitter's board initially resisted, before eventually being completed. In India, hostile takeovers are relatively rare but not unheard of, and they are governed by SEBI's Takeover Code which we will cover in a later chapter.

The three main modes of acquisition

When a company decides to acquire another, there are three ways it can structurally do that:

1. Acquisition of sharesThe acquirer buys the shares of the target company from its existing shareholders. This is the most common route. The company itself does not change — its contracts, employees, licences, and operations all stay intact. What changes is simply who owns it.

2. Acquisition of assets and liabilities on a going concern basis — the slump sale

Instead of buying the company, the acquirer buys the entire business as a running operation — assets and liabilities together, as one package, for a lump sum. The company itself is not acquired, but everything it runs is. This is called a slump sale, and it is a specific concept under Indian tax law that we will return to in more detail later.

3. Acquisition of specific assets — the asset saleHere the acquirer cherry-picks. They do not want the whole business — they want specific things. A particular factory, a brand, a piece of intellectual property, a customer list. This is called an itemised sale or asset sale. It gives the acquirer maximum control over exactly what they are taking on — and more importantly, what they are leaving behind.

Merger vs. Acquisition — the clearest way to understand the difference

The difference really comes down to two things: how the combination happens, and who is in control afterwards.

In a merger, two companies come together to form one new entity. It is mutual. Both sides agree, and control is restructured jointly.

In an acquisition, one company takes control of another — by buying its shares or its assets. The acquiring company remains in control. The target either becomes a subsidiary or disappears as an independent business.

Put simply — a merger is a mutual joining. An acquisition is one company taking the wheel.

In the next chapter, we will walk through the process of how an M&A deal actually unfolds — from the first conversation to the day the deal closes.
