Billionaire Mistry braces for fight over Tata stake value

As the billionaire Mistry clan and the Tata conglomerate head for a bitter split, they are already preparing for their next battle: the value of a stake in Tata Sons Pvt., which is at the center of India’s biggest corporate feud.

The Mistry family-owned Shapoorji Pallonji Group holds 18.4% of the holding company of the software-to-trucks Tata empire, and wants to sell it and raise funds for its own cash-strapped businesses. It had previously sought to pledge the shares as collateral, but was blocked this week when Tata told the Supreme Court it was open to buying the stock itself if Mistrys needed money.
