HP Wrote Off Most of What It Paid for Autonomy Within a Year
A technology acquisition completed in 2011 produced an enormous writedown in 2012, followed by a decade of litigation about whether the seller misrepresented or the buyer overpaid.
The Transaction
Hewlett Packard acquired the British software company Autonomy for approximately eleven billion dollars in 2011, at a substantial premium to the market price.
Roughly a year later HP recorded a writedown of around eight point eight billion dollars related to the acquisition, attributing a majority of it to accounting improprieties at Autonomy prior to the deal.
The Competing Explanations
Two accounts emerged and the litigation ran for years across jurisdictions.
HP alleged that Autonomy had misrepresented its business, including recognising hardware sales as software revenue, using resellers to recognise revenue on transactions where end customers had not committed, and overstating the proportion of high margin licence revenue.
The defence contended that HP had conducted its own diligence, had access to the accounts, understood what it was buying, and subsequently mismanaged the integration before seeking to blame the seller for its own overpayment.
Revenue quality mattered more than revenue quantity. Software licence revenue and hardware resale revenue justify very different multiples.
Why Revenue Mix Drove the Value
The substantive accounting dispute concerned classification rather than existence. If a company sells hardware at low margin and records it in a way that suggests high margin software licensing, total revenue is unaffected while the character of the business changes entirely.
Software businesses command high multiples because incremental revenue carries minimal cost and revenue tends to recur. Hardware resale is a low margin activity that does not merit comparable valuation.
An acquirer paying a software multiple for revenue that is substantially hardware resale overpays even if every transaction is real.
The Diligence Lesson
The case is instructive regardless of who was right. Financial diligence on an acquisition must go beyond confirming that revenue exists to establishing what kind of revenue it is.
That means examining contracts rather than summaries, understanding recognition policies in detail, testing whether revenue recognised through intermediaries corresponds to end customer demand, and assessing whether recurring revenue genuinely recurs.
These procedures are laborious, and acquisition timetables are compressed by competitive pressure and by executives who want the deal completed.
The Outcome
Litigation continued for more than a decade. An English court found substantially in HP's favour on the civil claim while indicating the damages would be considerably less than claimed, and criminal proceedings in the United States produced a conviction for one executive and, in a separate later trial, an acquittal for the founder.
The Bottom Line
The Autonomy dispute turned on what kind of revenue was being bought rather than whether it existed. Diligence that confirms revenue without characterising it has not established the value of anything.
