Global mergers and acquisitions fell to about $993 billion in the third quarter of 2026. That was a 41 percent drop from the previous quarter and the first quarter since the second quarter of 2025 in which global deal value fell below $1 trillion.

The slowdown does not mean companies have stopped buying other businesses. Large deals are still happening, especially in technology, artificial intelligence and industries connected to data centres.

But higher borrowing costs and uncertainty are making some companies think more carefully before committing huge amounts of money.

This matters because buying another company is one of the fastest ways to expand.

A business can gain new customers, technology, employees or access to a new market without building everything from the beginning.

But speed can also make an acquisition dangerous.

A company can spend billions on another business and later discover that the two companies are difficult to combine, the expected customers do not arrive or the technology does not produce the expected results.

Higher borrowing costs make the decision even harder.

When it costs more to borrow money, an acquisition becomes more expensive to finance.

Companies therefore have to be more confident that the deal will eventually produce enough value to justify the cost.

There is also more uncertainty around the global economy.

Energy costs, inflation, interest rates and rapid changes in artificial intelligence are making it harder for executives to predict what markets will look like several years from now.

Interestingly, global deal activity is not completely weak.

Total worldwide mergers and acquisitions for the year had reached about $3.9 trillion by the end of the third quarter, which was still 28 percent higher than the same period a year earlier.

The number of deals, however, had fallen by 8 percent.

This tells an important story.

Companies are still interested in growth, but they are becoming more selective about how they achieve it.

A smaller number of large deals can mean businesses are concentrating their money on opportunities they believe can produce the strongest results.

For businesses of any size, the lesson is simple.

Growth should not be measured only by how quickly a company expands.

Before spending heavily on another business, leaders need to understand what they are buying, what it will add and whether the business can actually manage the change.

This is where research and careful planning matter.
