In The M&A Failure Trap: Why Most Mergers and Acquisitions Fail and How the Few Succeed, Baruch Lev and Feng Gu provide a wealth of evidence on the success and failure factors of acquisitions.

Lev, professor emeritus of Accounting and Finance at NYU’s Stern School of Business and Gu, professor of Accounting and Law at the State University of New York, have analyzed more than 40,000 acquisitions over the past four decades. This has not only allowed them to understand the reasons why 75% of deals fail but also to develop a scorecard that can help decision-makers assess the likelihood of acquisition success ex ante.

In their conversation with Martin Reeves, chairman of the BCG Henderson Institute, Lev and Gu discuss how to measure acquisition success, how to curb overconfidence on the side of the acquirer, and key lessons for CEOs seeking inorganic growth.

Key topics discussed:
