Telecom And Fintech Integration Will Foster Sustainable Value

Key Takeaways

• Growth in advanced data services and integrated financial products is increasing customer retention and expanding revenue across both consumer and business segments.
  
• Continued investment in network modernization and digital solutions is strengthening KDDI's market position and supporting long-term profitability and business diversification.
  
• Reliance on saturated domestic market, slow subscriber growth, intense price competition, and weak diversification heighten risks to future revenue, earnings, and cash flow.

Catalysts

Engages in the provision of telecommunications services in Japan and internationally.

• Successful adoption of new high-capacity and data-focused pricing plans (au 5G Fast Lane, Starlink Direct, Unlimited Data MAX+) is driving higher ARPU and improved brand migration/churn trends, supporting growth in mobile revenue and net margins as digitalization accelerates data usage.
  
• Integration of financial services (e.g., collaboration with SBI Securities, expansion of au PAY and banking products) enables cross-selling between telecom and fintech, increasing customer stickiness, expanding revenue streams, and boosting long-term earnings potential.
  
• Sustained investment in network modernization (5G, Starlink, connectivity enhancements) positions KDDI to capitalize on increasing demand for advanced connectivity, supporting higher ARPU and future EBIT margin improvement as IoT and smart device adoption rises.
  
• Strategic emphasis on connected digital experiences and enterprise segments (cybersecurity, IoT, facility solutions) taps into long-term demand from demographic changes (aging population, remote services), driving business segment revenue diversification and margin expansion.
  
• Growth focus on lifetime value and engagement of highly-connected customers in both Personal and Business Services, amid industry stagnation, may allow KDDI to outperform peers in revenue growth and profitability through enhanced bundling and integration.

KDDI Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming KDDI's revenue will grow by 3.5% annually over the next 3 years.
• Analysts assume that profit margins will increase from 11.4% today to 12.5% in 3 years time.
• Analysts expect earnings to reach ¥825.7 billion (and earnings per share of ¥227.4) by about September 2028, up from ¥679.8 billion today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 13.7x on those 2028 earnings, down from 14.2x today. This future PE is lower than the current PE for the JP Wireless Telecom industry at 21.6x.
• Analysts expect the number of shares outstanding to decline by 1.31% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 4.72%, as per the Simply Wall St company report.

KDDI Future Earnings Per Share Growth

Risks

• By relying heavily on ARPU increases driven by recent repricing and new plans, KDDI's current revenue growth appears less organic; future growth may struggle if subscriber additions stagnate, directly constraining top-line revenue and profit growth.
  
• The company is experiencing slow net additions in smartphone subscriptions and admits that churn rates recently rose, indicating increased competition and potential inability to grow or even maintain its subscriber base, which could put downward pressure on both revenue and earnings.
  
• Ongoing aggressive price competition-especially in the low-capacity/low-usage segment-limits KDDI's ability to capture new subscribers and extract incremental revenue, threatening long-term ARPU improvement and net margins as the market saturates further.
  
• Persistent sluggishness or weak profitability in key growth areas such as digital BPO and data centers suggests diversification beyond core telecom remains uncertain, which could limit KDDI's ability to offset declining legacy revenues and thus dampen future earnings and free cash flow.
  
• The company continues to signal that much of its growth strategy is contingent on the aging, saturated domestic market with limited geographic diversification, exposing it to structural demographic declines and concentrated market risk-potentially resulting in stagnating or declining long-term revenue and net income.

Valuation

• The analysts have a consensus price target of ¥2688.333 for KDDI 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 ¥3150.0, and the most bearish reporting a price target of just ¥1865.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be ¥6620.6 billion, earnings will come to ¥825.7 billion, and it would be trading on a PE ratio of 13.7x, assuming you use a discount rate of 4.7%.
• Given the current share price of ¥2534.0, the analyst price target of ¥2688.33 is 5.7% higher. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
• 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.
