And when buyers feel unable to conduct enough due diligence, our survey finds that many (44 percent) buyers are unafraid to walk away.

But macro factors can also throw a wrench into the works: 57 percent of respondents said they had walked away from a deal because of the changing macroeconomic environment.

When it comes to legal or regulatory issues, political meddling is the number-one reason why acquirers leave the negotiating table.

Meanwhile, more than half of respondents (55 percent) say that incompatibility with the target's management has prompted them to leave the table, while 52 percent say that lack of confidence in a target's growth prospects has put them off. When it comes to legal or regulatory issues, political meddling is the number-one reason why acquirers have abandoned a transaction, highlighted by 70 percent of respondents.

A China-based tech acquirer says: "There was direct interference from the government when we wanted to acquire a target in Western Europe. We tolerated this to an extent but when the interference got to the strategic level, we had no option but to walk out of the deal."

Antitrust rules are also turning deals sour, with 62 percent of respondents who have walked away from deals citing uncertainty around competition regulations.

Governments are increasing the level of scrutiny under national security policies that apply to foreign investments. The regulatory environment is becoming less forgiving, and businesses will need to take this into account as they plan their future transactions.
