“This is a landmark day in Autonomy’s history,” Mike Lynch declared in a press release on August 18, 2011, as he announced the sale of his software company, Autonomy, to Hewlett-Packard for $11 billion.

June 6, 2024, will be an even more significant date for Lynch.

After nearly 13 tumultuous years and a drawn-out trial in the heart of Silicon Valley, Lynch, once known as the “British Bill Gates,” has been cleared of fraud charges. The verdict marks a stunning reversal of fortune for the entrepreneur.

Lynch said Thursday he was “overjoyed” at his acquittal. “The truth has finally prevailed,” his lawyers declared.

He is now due to return to Britain, but the fight to clear his name continues. HP nearly won a civil lawsuit against Lynch and another Autonomy head, Sushoban Hussain, in London two years ago. The company is seeking $4 billion in damages. Lynch had previously said he would appeal the decision.

By all accounts, the acquisition was a disaster. Just five weeks after it was announced, HP’s CEO, who had signed the deal, was fired. Lynch left Autonomy less than a year later. The lucrative acquisition briefly cemented Lynch’s reputation as Britain’s most successful tech mogul. Its real legacy was more than a decade of bitter legal battles.

In November 2012, HP’s new management wrote down the value of Autonomy by $8.8 billion, alleging “significant” accounting irregularities, disclosure deficiencies, and “plain misrepresentations” prior to the acquisition. After years of investigations and legal proceedings on both sides of the Atlantic, a US federal grand jury indicted Lynch on criminal charges in November 2018. After the civil proceedings were concluded, the UK agreed to Lynch’s extradition.

His legal troubles grew last year. Having nearly lost a British civil lawsuit, Lynch also lost an appeal against his extradition in the UK High Court. A few weeks later, he was on a plane to California.

The trial in San Francisco has been a tough test for Lynch, who has been fighting to avoid extradition to the U.S. to face more than a dozen fraud charges. Federal prosecutors have a horrific record of convictions, forcing Lynch’s defense team to adjust their defense ahead of the trial.

From the start of the saga, Lynch has maintained that Autonomy’s collapse was the result of mismanagement of valuable HP assets, not fraud, but rather the failure of HP to provide evidence to support that claim, but U.S. District Judge Charles Breyer, who presided over the case, has barred Lynch’s lawyers from presenting evidence to support that claim.

Failing to focus on the post-acquisition situation, Lynch’s defense was based on three main arguments: first, that running a company like Autonomy is much more complicated than the prosecution would have the jury believe, second, that Lynch is a very different person to the person he has been portrayed to be, and third, that HP rushed to conduct its due diligence and close the deal.

One of Lynch’s lawyers, Reid Weingarten, declared on the first day of the trial that the government’s case was “black and white,” “and this trial is going to show that that’s not how the world works. The world works in shades of gray. The world is complicated.”

Life is “delicate and messy”, Lynch told the court, suggesting that his trial is effectively “like peering through the door to watch sausages being made. The thing you have to bear in mind is that if you take a microscope to a clean kitchen, you’re going to find germs. And I think Autonomy is no exception.”

Prosecutors tried to portray Lynch as an intimidating, ruthless businessman responsible for every aspect of the Autonomy empire. Jurors heard about the piranha tank in the atrium of the company’s headquarters and conference rooms named after James Bond villains.

Lynch said he found it “surreal” to hear government witnesses testify about many discussions and decisions he was unaware of. He said he delegated work that was outside his expertise and spent “about 30 percent” of his time at Autonomy in his later years spending time with his family and pursuing other hobbies.

“I believe the more you know about him, the better it is for us,” Weingarten told jurors before Lynch’s testimony.

Prosecutors said Mr Lynch had “half a billion reasons” to commit the fraud – one for every pound he claimed to have made from HP’s acquisition of Autonomy – but Mr Lynch said the company wanted to remain independent.

Autonomy is one of the stars of London’s FTSE 100 stock index and is still in the process of acquiring itself. Lynch says he only started considering the idea after meeting with HP executives at a luxury home in the English countryside. It was the 64% premium on Autonomy’s shares that ultimately convinced the company to accept the deal.

Lynch argued that HP was determined to rapidly transform itself from a hardware maker into a software giant. press release It was only when it was released that the company announced it was buying his company, a process he recalled on the stand as “total chaos.”

Prosecutors argued that HP’s handling of the proceedings was irrelevant: They alleged that Lynch orchestrated a massive fraud over years and that Autonomy used a variety of accounting tricks to inflate sales growth.

But Lynch stressed that HP was “not at all” misled about Autonomy’s value. A California jury believed Lynch and dismissed the case, which the U.S. government had detailed, calling more than 30 witnesses.

Six years ago, a jury in the same court came to a different conclusion about one of Lynch’s closest business partners. Hussain, who served as Autonomy’s chief financial officer, was convicted of conspiracy, wire fraud and securities fraud in connection with the deal in 2018. He was released from a U.S. prison in January after serving a five-year sentence.

Lynch, who was awarded an OBE at the height of his career and served as an adviser to the British prime minister, spent much of the year before his trial under effective house arrest, guarded around the clock by two armed guards, and the threat of more than 20 years in prison loomed large if convicted.

The businessman left court a free man on Thursday. “I look forward to returning to the UK and getting back to what I love most – my family and innovating in my field,” he said.

Another important day.
