SoftBank (9984.T)

Key Updates

SoftBank shares declined 2.56% to ¥5,858 on May 14, extending the correction from the May 7 daily limit high of ¥6,424. This marks the fourth decline in five sessions, with cumulative losses of 8.81% over five days despite the stock maintaining robust YTD gains of 33.14%. The pullback follows exceptional FY2025 results announced May 13, where net profit quadrupled to ¥5.003 trillion ($31.74 billion) on $43.9 billion in OpenAI valuation gains. The disconnect between fundamental performance and price action suggests profit-taking after the 64% April rally, while new strategic initiatives including the $100 billion Roze data center IPO and battery venture launch demonstrate continued AI infrastructure expansion.

Current Trend

SoftBank maintains a strong uptrend with YTD gains of 33.14% and 6-month appreciation of 18.46%, though short-term momentum has reversed sharply. The stock surged 38.10% over one month, driven by the April recovery from geopolitical concerns and renewed AI optimism, but has corrected 8.81% over five days from the May 7 peak. The current price of ¥5,858 sits approximately 8.8% below the recent high of ¥6,424, establishing resistance at that level. Support appears near the ¥5,747 level tested on May 11. The technical pattern suggests a healthy consolidation within a broader uptrend, with the stock digesting rapid gains while maintaining elevation above key moving averages. Trading volumes during the decline have been moderate, indicating profit-taking rather than fundamental deterioration.

Investment Thesis

The investment thesis centers on SoftBank's position as the premier publicly-traded proxy for OpenAI exposure, amplified by strategic AI infrastructure initiatives across data centers, semiconductors, and energy. The company's $64.6 billion total OpenAI commitment has generated $43.9 billion in cumulative gains, validating the AI investment strategy. This thesis is reinforced by three strategic pillars: (1) the 90% stake in Arm Holdings, benefiting from AI chip demand with 60% monthly share price gains; (2) the planned $100 billion Roze IPO targeting AI-optimized data center construction using robotics and proprietary technologies; and (3) vertical integration through the battery venture with Cosmos Lab and DeltaX, targeting ¥100 billion annual revenue by 2030. The convergence of these initiatives positions SoftBank to capture value across the AI infrastructure stack, from chip design through data center construction to power generation. However, execution risks remain substantial, with concerns about the Roze valuation and timeline, estimated $35.7 billion funding shortfall, and loan-to-value ratio management despite improvement to approximately 11%.

Thesis Status

The investment thesis has strengthened materially despite recent price weakness. The FY2025 results announced May 13 exceeded analyst estimates by 41.7% (¥5.003 trillion vs. ¥3.531 trillion expected), with Vision Funds recording ¥6.445 trillion profit versus a ¥115.02 billion loss in the prior year, as reported by Morningstar. The OpenAI investment has delivered $43.9 billion in gains, representing approximately 68% return on the current $64.6 billion commitment. New strategic initiatives validate the thesis expansion beyond financial investment into operational AI infrastructure. The Roze venture leverages existing assets including SB Energy Inc., which has completed projects for OpenAI and Google Cloud, while incorporating ABB Group's robotics business acquired for $5.4 billion, as detailed by SiliconANGLE. The battery venture addresses a critical bottleneck in AI infrastructure with production commencing fiscal 2028, per WSJ. Balance sheet concerns persist with the $35.7 billion estimated funding shortfall noted by CreditSights in the Reuters bond offering coverage, though improved loan-to-value ratio and strong underlying asset values provide cushion.

Key Drivers

Near-term catalysts include the Roze IPO execution, targeted for year-end 2026 at a $100 billion valuation on a U.S. exchange, which would provide significant proceeds to fund AI investments and reduce leverage, as reported by SiliconANGLE. The battery venture commercialization timeline, with production starting fiscal 2028 and mass production in 2029, positions SoftBank to capture energy infrastructure value, per WSJ. OpenAI's operational performance remains critical, with recent reports of Codex AI coding tool reaching four million weekly active users (up from three million two weeks prior) demonstrating sustained product momentum, as noted by Morningstar. Arm Holdings' strong fiscal Q4 results and demand for new computer chips provide subsidiary support, per Morningstar. The appointment of Arm CEO Rene Haas with expanded semiconductor and AI responsibilities signals strategic alignment across the portfolio, as covered by WSJ. Geopolitical stability, particularly easing U.S.-Iran tensions, supports technology sector sentiment and SoftBank's AI-focused positioning.

Technical Analysis

SoftBank exhibits a corrective phase within a robust primary uptrend. The stock reached a daily limit high of ¥6,424 on May 7 (+18%), establishing clear resistance at that level. The subsequent five-day decline of 8.81% to ¥5,858 represents a 61.8% Fibonacci retracement of the April rally from approximately ¥3,900 to ¥6,424, suggesting technical consolidation rather than trend reversal. Support was tested at ¥5,747 on May 11 (-6.26% that session), which held on subsequent tests. The current price of ¥5,858 sits midway between support and resistance, with the stock maintaining position above the rising 50-day moving average. Volume patterns during the decline have been moderate, lacking the intensity that would signal distribution. The YTD gain of 33.14% and 6-month advance of 18.46% confirm the broader uptrend remains intact. Key technical levels: resistance at ¥6,424 (May 7 high), support at ¥5,747 (May 11 low), with a break below ¥5,500 potentially signaling deeper correction toward the ¥5,000 psychological level.

Bull Case

Bear Case

• Roze Execution Risk and Valuation Concerns: Financial Times reports that some executives believe the $100 billion valuation target and year-end 2026 timeline may be too ambitious and subject to change, introducing uncertainty around a key value catalyst and potential proceeds to address the funding shortfall. Source
• Substantial Funding Shortfall: CreditSights estimates a $35.7 billion funding gap following the $30 billion OpenAI commitment, with the balance sheet described as "stretched," requiring continued debt issuance at elevated rates (7.625%-8.5% for dollar bonds, 6.375%-7.375% for euro bonds) and potential asset sales to maintain liquidity. Source
• OpenAI Concentration Risk: With total OpenAI investment reaching $64.6 billion (including the $30 billion phased commitment through October), SoftBank's performance is highly concentrated in a single private company valuation, with limited near-term liquidity and exposure to competitive threats in the rapidly evolving AI landscape. Source
• Extended Battery Venture Timeline: Commercial battery production does not commence until fiscal 2028, with mass production targeted for 2029 and revenue goals for fiscal 2030, creating a 4-6 year timeline before meaningful contribution to earnings while requiring substantial upfront capital investment during the funding shortfall period. Source
• Technical Correction Momentum: The stock has declined 8.81% over five days from the May 7 peak, with resistance established at ¥6,424 and the recent 64% April rally creating elevated valuation expectations that may require extended consolidation, particularly if broader technology sector sentiment deteriorates or geopolitical tensions re-emerge.
