Nvidia jumps on $40 billion Arm deal; analysts expect tough scrutiny

Shares of Nvidia Corp rose 6% on Monday after it announced a $40 billion deal to buy UK-based chip designer Arm from Japan’s SoftBank Group Corp that, if completed, would be the chip industry’s biggest ever merger.

The deal vaults Nvidia into the very top echelon of the world’s chip suppliers and its stock, which has more than doubled this year, gained 5.8% to $514.9 in early trading.

Shares in SoftBank, under pressure for months after a torrid year dominated by the troubles of its WeWork shared office venture, jumped 10%.

A host of analysts were quick to flag significant regulatory hurdles including from China for the buyout, which is seen to have big implications for the global semiconductor landscape.
