15 Biggest Acquisitions Of All Time

In this article we are going to list the 15 biggest acquisitions of all time. For a detailed coverage of this topic and a more comprehensive list please head on over to the 5 biggest acquisitions of all time.

We've seen some giant companies throughout history, many of which have actually been broken by the regulators in the country for being monopolies. For example, Standard Oil was the biggest company in the world by far at the time, but actually had a monopoly on the oil industry, which itself is one of the biggest and very lucrative industries in the world. This is why the owner of Standard Oil, John D. Rockefeller, is still the richest man to have ever existed in modern times. Adjusted for inflation, his net worth is said to be around $350 billion to $420 billion, which means that the current richest men in the world, Elon Musk and Jeff Bezos, with the former currently worth over $200 billion, have to do a lot more to catch up. Of course, the way Tesla and Amazon's value grew significantly in a year which absolutely wrecked the global economy due to the Covid-19 pandemic, the sky seems to be the limit and in a few years (or not even that), we could see these two men eclipse the wealth that John D. Rockefeller amassed more than a century ago.

While Tesla and Amazon may have grown significantly and are now counted among the most valuable companies in the world, the current most valuable company in the world is Apple, with a market cap of more than $2.237 trillion, which is more than the GDP of the vast majority of the nations in the world. And while these companies may have mostly grown organically, that is not true for most of the companies that are ranked among the biggest in their industry.

Companies grow through two ways; organically or through mergers and acquisitions. Growing organically means that the company slowly and steadily increases its sales and its market share, which doesn't happen in a day. It takes years and even decades to grown organically, and many companies don't take that route. Instead, many companies go through the rate of mergers and acquisitions. Now, there is a difference between the two, but in a sense, both require the purchase of shares of a company. Now, the reason most companies do this is to gain more dominance within the industry, and the most popular reason for mergers and acquisitions is synergies. Synergy is a term used to describe that the sum of the parts is worth more than the individual parts. By combining the resources of two or more companies, the expectation is that it will bring more benefits to the company than just the additional sales or market share. However, as many examples throughout history have proven, the idea of synergies is easier to imagine than to translate it into reality. In fact, according to a report by Harvard Business Review, most mergers and acquisitions fail, with the failure rate being between 70% to 90%.

One of the reasons behind these failures is the fact that there are a lot of clashes between the two companies being merged. Often, the companies have different corporate views, different goals, different cultures and different ways of working, and integrating two companies under a single banner is easier said than done. Despite this, when its successful, it can often be worth it, which is why companies often spend tens of billions, if not hundreds of billions of dollars on such deals. Below, we have a list of such companies, ranked according to the value of the deal, adjusted for inflation. So without further ado, let's take a look at the biggest deals ever made in history, starting with number 15:
