Last week we asked the question Could it get any worse? Well, Toby has excelled as usual and the acquisition of Autonomy must go down in history as one of the worst, most value-destroying deals in the history of the Tech Industry and Corporate America.This story is a bit like “Air Crash Investigations”. It’s not just one factor that conspired in a complete M&A disaster, but a number. Let’s list them:A CEO desperate to make a deal and rushed the processTwo diametrically opposing cultures:A large unwieldy and bureaucratic buyerAn aggressive “in-your-face” software firm big on personality, entrepreneurship and suspect sales practicesA board with several new people with limited time to focus on the deal.A CFO who said “don’t do the deal”; roundly ignored.A Due Diligence process with limited financial transparency and an over reliance on ‘audited’ accounts.A lack of integration planning that would handle different cultures and make the deal work.A very optimistic valuation indeed;  way above market expectations.AND a $8Bn write-down within one year of the deal closingSo apologies for our listeners, this one is over 30 minutes duration, but it's necessary to cover all of the salient points of this tech industry disaster.
