Interesting article by Paul Siegenthaler author of the highly recommended book “Perfect M&As” about the 10 main reasons for M&A failure.

Paul highlights poor due diligence as one of the key factors that make M&A transactions fail. I cannot agree more. In the last 20 years I have participated in a number of transactions in which value was destroyed due to poor due diligence.

The main reasons that I see for poor due diligence are:

– Asking the wrong questions.  Focusing on details before deciding what actually drives value for the acquisition.

– Disconnect between the deal team and the due diligence team.  In many transactions, there is a significant gap between the deal team and the team executing the due diligence whereas the deal team just sees the due diligence findings as hurdles.

– No real business due diligence.  Many DD processes turn into a legal/financial/risk audit too early into the process, ignoring the “real” business due diligence.

– Organization of information.  Many data rooms do not take advantage of the great deal tools that most virtual data room provide such as organization of folders, Question and Answer, reporting.
