SoftBank Group Corp. - FY2025 Earnings Analysis

Performance Highlights

SoftBank Group reported FY2025 net income of ¥5,002.3 billion, the highest ever recorded by a Japanese corporation, against ¥1,153.3 billion in FY2024, a gain of ¥3,848.9 billion year-on-year. Net sales rose 7.7% to ¥7,798.7 billion, income before income tax surged to ¥6,134.9 billion, and gain on investments more than doubled to ¥7,286.5 billion, each representing substantial beats relative to prior-year baselines.

The dominant driver was the revaluation of Arm, whose market capitalisation reached approximately $221 billion as of May 12, 2026, a 4.2x increase since its September 2023 IPO, while the OpenAI stake appreciated roughly 5x from SBG's initial investment to a pre-money valuation of $730 billion by February 2026. Supporting these gains, the SoftBank Vision Fund segment swung to a cumulative investment gain of $45.7 billion, a $46.2 billion improvement year-on-year, and Arm posted record revenue of $4.92 billion, up 23% year-on-year, with non-GAAP fully-diluted EPS rising to $1.77.

Management Outlook and Forward Catalysts

Management framed FY2025 as an inflection point rather than a destination, committing a further $30 billion to OpenAI to bring total investment to $64.6 billion and approximately 13% ownership by October 2026, while Arm set a five-year revenue target exceeding $25 billion and non-GAAP EPS above $9. The announcement of the 10GW PORTS Technology Campus in Ohio, co-developed with the U.S. DOE and AEP Ohio, signals SBG's ambition to become a vertically integrated artificial superintelligence infrastructure provider spanning chips, models, data centres, and physical AI robotics.

The central investor debate heading into FY2026 is whether SBG can convert its record paper gains into durable cash flows as it deploys a committed $38.5 billion investment pipeline against an LTV of 17% and a fully drawn bridge loan, with bulls focused on Arm's chip revenue ramp and OpenAI's accelerating enterprise monetisation, and bears watching concentration risk, execution on the ABB Robotics integration, and the sensitivity of NAV to public market corrections.
