1. Overpaying

This is probably the most common reason for the failure of transactions. Most attractive target companies operate under the assumption that ‘everything is for sale at the right price’.

This effectively translates to ‘the business is always for sale when a buyer is willing to overpay.’

In publicly listed companies, this usually means a premium over the share price. There’s little reason to doubt it’s any different in small, privately-held companies.

It’s important for buyers to set a limit before negotiations start and stick to it to minimize the chances of overpaying.

2. Overestimating synergies

Overestimating synergies go hand-in-hand with overpaying in a transaction.

Overestimating the synergies inherent in a transaction is often the first step in overpaying.

While the idea that many costs will largely stay the same as two companies combined is alluring, it’s also far more difficult to achieve in practice than most managers are willing to admit. And revenue synergies are no less complicated to achieve.

For this reason, practitioners of M&A would be well advised to look at potential synergies from a transaction through a highly conservative lens.

3. Insufficient due diligence

The importance of due diligence can never be emphasized enough, partly because so many firms are evidently keen to get it over with as soon as possible.

One of the major problems that arise during the process is that the acquirer is depending on the target company to provide information that isn’t always complimentary to their management. This creates obvious agency problems.

By extension, the more uncomplimentary the information, the more the target company team is likely to withhold it and/or explain it away.

In extreme cases, this can lead to the failure of the transaction in the long run.

4. Misunderstanding the target company

Even due diligence doesn’t guarantee that you’ll fully understand the target company.

It gives you the best opportunity to do so, but there are plenty of cases where even a lengthy period of due diligence doesn’t let you know what makes a company tick.

The example of British grocery retailer Morrisson’s acquiring rival company Safeway in 2003 is a testament to this.

What looked on paper like a great deal for Morrisson’s – expanding their footprint all over the UK – turned into a nightmare, essentially because the two firms served completely different types of customers.

5. Lack of a strategic plan

A good ‘why’ is an essential component of all successful M&A transactions. That is, without a good motive for a transaction, it’s doomed to failure from the outset.

Academic literature on M&A is replete with studies of managers engaging in ‘empire building’ through M&A, and research into how hubris is a common trend in M&A.

M&A success factors

A good rule of thumb here is that the less simply the motive for the transaction can be explained, the more likely it is to be a failure.

‘Market share’ is a good motive; ‘become a visionary in the industry’ is not.

6. Lack of cultural fit

Perhaps ‘inability to acknowledge cultural differences’ might be a better title.


Because the cultural difference is not a problem – rather, it’s the inability (or unwillingness) to acknowledge them and look to bridge the gap.

It’s vital that any two companies engaging in a transaction use a change manager to oversee the process.

Underestimating this element of mergers and acquisitions as merely a ‘soft area’ of the transaction has led to billions of dollars being destroyed over the years.

7. Overextending resources

Target companies that are small in size relative to the acquiring company – are usually considered to be the best type of transactions.

One of the main strands of thought behind this is that they don’t require as many resources to be acquired or to be integrated.

On the other side of this equation, are those transactions that require significant resources on the part of the acquiring firm.

Loading up on debt to acquire any firm creates pressure from day one to cut costs – never a good start for a deal, and often the beginning of the end.

8. Wrong time in industry cycle

For the myriad of reasons cited for the failure of the notorious AOL/Time Warner deal, one is seldom given: The year 2000 was not a good time for media firms to merge.

The media industry was about to undergo the biggest shake-up in its history, from which it is only now beginning to show signs of recovery.

9. External factors

External factors refers to everything that’s out of the manager’s control. 2020 provides us with a readily available example.

Suppose the managers of two hotel chains are considering a merger. It makes sense on almost every level – financial, cultural, and strategic.

There is no overlap in geography, meaning regional hotel chains are joining to create a national chain.

On paper, it is perfect. As soon as the deal closes, a pandemic sweeps the world, tourism stops and money dries up.

The deal has been a failure because of external factors that few could have foreseen.

10. Lack of management involvement

The most obvious reason for failure is left for last. Management involvement is something of a catch-all answer and often incorporates many of the other reasons on this list.

No stage of the M&A process will manage itself, be it the search for a suitable target firm to the integration of the two firms into the newly formed entity.

When managers deem other tasks in their company to be more important than the successful implementation of M&A, they shouldn’t be surprised when their deal has eventually deemed a failure.
