Homegrown LLMs And AI Will Expand Japan Digital Markets

Key Takeaways

• Accelerating investment in AI, fintech, and digital infrastructure boosts recurring revenue streams, margin expansion, and monetization through partnerships and new service offerings.
  
• Strategic focus on semiconductors and global collaborations bolsters Japan's tech self-sufficiency while reducing supply chain and geopolitical risks for sustained softbank growth.
  
• Mounting competition, rising costs, uncertain investments, and segment volatility threaten SoftBank's growth, margins, and profitability across core business areas.

Catalysts

Engages in the telecommunication and information technology businesses in Japan.

• Planned rollout of homegrown large language models (LLMs) and commercial GPU as a service targeting Japan-based enterprises capitalizes on surging enterprise AI adoption, which is set to accelerate recurring revenues and support margin expansion from higher-value digital infrastructure services.
  
• Integration of AI solutions (e.g., contact center agentic AI) into financial services partnerships with firms like Sumitomo Mitsui Card and PayPay creates new monetization channels, further increasing transaction volume, cross-selling opportunities, and supporting top-line revenue and net income growth.
  
• Robust expansion in digital payments and fintech (PayPay's 24% year-on-year GMV growth and 87% EBITDA growth) demonstrates SoftBank's strong leverage to the ongoing digitalization of the Japanese and broader Asian economies, increasing both transaction-driven revenues and underpinning future realized gains from potential IPO activity.
  
• Continued scaling of digital infrastructure (data centers, 5G network migration, and capacity expansion up to 300MW) positions SoftBank to benefit from the proliferation of connected devices and enterprise cloud migration, driving network/data usage, growing ARPU, and enabling additional high-margin platform services.
  
• Strategic investment in domestic semiconductor initiatives (e.g., Rapidus) and collaborations with global technology leaders (e.g., NVIDIA) are likely to strengthen Japan's self-sufficiency in next-gen computing, supporting sustained long-term growth in SoftBank's technology and telecom portfolio and reducing future earnings volatility tied to supply chain/geopolitical risks.

SoftBank Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

• Analysts are assuming SoftBank's revenue will grow by 5.4% annually over the next 3 years.
• Analysts assume that profit margins will increase from 7.7% today to 8.1% in 3 years time.
• Analysts expect earnings to reach ¥669.9 billion (and earnings per share of ¥14.11) by about June 2029, up from ¥541.4 billion today. However, there is some disagreement amongst the analysts with the more bullish ones expecting earnings as high as ¥740.5 billion.
• In order for the above numbers to justify the price target of the analysts, the company would need to trade at a PE ratio of 20.2x on those 2029 earnings, up from 18.8x today. This future PE is lower than the current PE for the JP Wireless Telecom industry at 20.6x.
• Analysts expect the number of shares outstanding to grow by 0.36% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 4.91%, as per the Simply Wall St company report.

Risks

• Intensifying price competition and difficulty raising tariffs in Japan's saturated wireless market, as SoftBank management repeatedly expressed concerns about consumer acceptance and the risk of customer churn if they follow competitors' price hikes-likely limiting ARPU growth, profit margins, and future revenue scalability.
  
• Rising costs for labor, administration, and network upgrades (e.g., planned 5G standalone transition, expanded data centers, increased staff compensation), with limited ability to pass them on to consumers, risk compressing net margins and eroding profitability over the long term.
  
• Ongoing volatility in Media & E-commerce and Finance segments, with management acknowledging recent significant share price declines (e.g., LINE Yahoo!, Rakuten) and potential continued struggles in e-commerce-jeopardizing segment revenues, creating possible impairment risks, and reducing overall net earnings.
  
• Uncertainty and capital intensity surrounding AI and data center investments (e.g., large-scale GPU deployment, R&D spending, Sakai expansion up to 300MW), which could lead to substantial upfront capex without matched demand or guaranteed payback-potentially straining cash flow, elevating debt, and depressing return on invested capital.
  
• Structural challenges in SoftBank's low-priced, low-volume data plans (LINEMO/Y!mobile), with active competition from aggressive challengers like Rakuten and possible brand cannibalization, risking customer migration to cheaper offerings, reducing ARPU, and creating further revenue and net margin headwinds in the consumer segment.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The analysts have a consensus price target of ¥242.53 for SoftBank based on their expectations of its future earnings growth, profit margins and other risk factors.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of ¥270.0, and the most bearish reporting a price target of just ¥205.0.
• In order for you to agree with the analysts, you'd need to believe that by 2029, revenues will be ¥8243.4 billion, earnings will come to ¥669.9 billion, and it would be trading on a PE ratio of 20.2x, assuming you use a discount rate of 4.9%.
• Given the current share price of ¥213.2, the analyst price target of ¥242.53 is 12.1% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
