Mike Lynch’s estate ordered to pay £920m to HPE

Apparently the matter was not settled when Lynch was cleared of fraud. Or died.

The British High Court has ordered the estate of tech tycoon Mike Lynch to pay £920 million to HPE, over Lynch’s liability in the case of the Autonomy acquisition.

The High Court also refused an appeal by the estate against the same.

The decision keeps in place a judgment that dates back to the long‑running dispute over HPE’s £11.1bn purchase of Autonomy in 2011, a deal that quickly unravelled and became one of the tech sector’s most contested acquisitions.

HPE accused Lynch and Autonomy’s former finance chief, Sushovan Hussain, of inflating the company’s financial position before the sale. Just over a year after the acquisition, HP wrote down Autonomy’s value by $8.8bn and later launched civil proceedings in the UK courts.

In 2022, the High Court ruled HP had succeeded in its claim that it paid more for Autonomy than it would have done had it known the company’s true financial position.

A later ruling assessed HP’s losses at close to £700m, with costs and interest taking that to the final £920m figure.

Although this is far below the $4.55 billion HP claims it is owed, it could still bankrupt Lynch’s estate, which is estimated to be worth about £500m.

Lawyers acting for the estate asked the court for permission to appeal both the finding of liability and parts of the damages ruling. The judge rejected that request, although the estate can still apply directly to the Court of Appeal.

Lynch spent much of the previous decade fighting legal action linked to the Autonomy deal, and faced criminal fraud charges brought by federal prosecutors in the US. However, he was cleared by a jury in 2024.

Sadly, he died shortly afterwards when his yacht sank off the coast of Sicily – while celebrating the ruling.

Throughout the dispute, Lynch denied wrongdoing, arguing that HP failed to understand Autonomy’s business and mishandled its integration after the acquisition. HP has consistently rejected that account and has maintained that the losses stemmed from misrepresentation before the deal completed.

The Autonomy case has had a lasting impact on the UK technology sector. At the time, the deal was the largest acquisition of a British software company and was seen as a landmark moment for the industry. Its collapse helped reshape how large technology acquisitions are scrutinised by boards, investors and auditors.
