SoftBank's Arm aims to raise at least $8 billion in U.S. IPO, sources say

Arm Ltd, the British chip designer owned by Japan’s SoftBank Group Corp (9984.T), is likely to aim to raise at least $8 billion from what is expected to be a blockbuster U.S. stock market launch this year, people familiar with the matter said on Sunday.

Arm is expected to confidentially submit paperwork for its initial public offering in late April, the sources said, speaking on condition of anonymity because the discussions are confidential. The listing is expected to happen later this year and the exact timing will be determined by market conditions, the sources added.

SoftBank has picked four investment banks to lead what is expected to be the most high-profile stock market flotation in recent years. Goldman Sachs Group Inc (GS.N), JPMorgan Chase & Co (JPM.N), Barclays (BARC.L) and Mizuho Financial Group (8411.T) are expected to be the lead underwriters for the deal, the sources said, adding that no bank has been picked for the much-coveted “lead left” position yet

The preparations for the IPO are expected to be kick-started in the U.S. in the coming days, the sources said. The valuation range has not yet been finalized but Cambridge, England-based Arm is hoping to be valued at more than $50 billion during its share sale, the sources said.
