A federal jury found Autonomy Corp.’s former financial chief guilty of falsifying financial statements and exaggerating the British software maker’s value before its sale to Hewlett-Packard for $11 billion in 2011.

If upheld, the fraud conviction of Sushovan Hussain after a six-week trial in San Francisco would offer some vindication to H-P executives who have long alleged Autonomy’s management cooked the books before one of its biggest acquisitions.

H-P initially billed the acquisition as key to transforming itself into a software powerhouse and anchor its forays into hot fields like data and analytics. Instead, the deal was an embarrassment for H-P, which took an $8.8 billion charge and grappled with shareholder lawsuits. H-P later split into two companies and sold off parts of Autonomy.

The federal jury found Mr. Hussain guilty on 16 separate counts of wire and securities fraud after prosecutors brought charges against him in November 2016 for engaging in a “fraudulent scheme” to deceive Autonomy’s investors and H-P about the company’s financial health and prospects for growth.

Acting U.S. Attorney Alex G. Tse said Mr. Hussain’s false and misleading statements defrauded HP of more than $11.7 billion.
