Arm's sales fell to $2.68 billion in the 12 months ended March 31, hurt by a slump in global smartphone shipments, the source said, requesting anonymity. In May, SoftBank reported that revenue for the year at Arm had grown 5.7% under International Financial Reporting Standards. Arm will disclose its latest financials next week under the U.S. accounting standards, the source added. Reuters had previously reported that SoftBank was aiming to list Arm at a valuation of $60 billion to $70 billion in the IPO. Arm's IPO preparations are being led by Goldman Sachs Group (GS.N), JPMorgan Chase (JPM.N), Barclays Plc (BARC.L) and Mizuho Financial Group.
