Recent Overview
Revenue rose 3.9% year on year, but operating income fell 7.7% due to higher costs
In FY2026 (ending March 2026), the Integrated ICT Business achieved operating revenue of ¥6,458,073 million (up 3.9% year on year), while operating expenses increased 6.2% year on year, leaving operating income at ¥942,062 million (down 7.7% year on year). The consolidation of SBI Sumishin Net Bank as a subsidiary (October 2025) drove full-scale expansion of the financial business. Growth in the Smart Life Business and aggressive investment in 5G base stations were the main drivers of the cost increase.
Key Products
Growth Drivers
- Expansion of the Smart Life Business (finance, payments, marketing solutions): launch of "d NEOBANK" following the consolidation of SBI Sumishin Net Bank as a subsidiary, and transition to the "NTT DOCOMO Financial Group" structure
- Improved communication quality and sustained/expanded customer base through aggressive rollout of 5G base stations: new rate plans such as "docomo MAX" surpassed 3 million subscriptions by March 2026
- Expansion of the enterprise customer base through the rollout of the enterprise NaaS "docomo business RINK®" and strengthened partner collaboration
- Monetization of the entertainment domain through use of IOWN and Wi-Fi 7 at venue businesses (MUFG Stadium, IG Arena, etc.)
- Advancing the societal implementation of AI solutions leveraging LLMs (such as robotic automatic control cloud services)
Risks
- Impact on operating cash flow and rising financial leverage from an increase in bank lending etc. associated with the consolidation of SBI Sumishin Net Bank as a subsidiary
- Decline in operating margin (from 16.4% in the prior period to 14.6% in the current period) due to ballooning operating expenses (up 6.2% year on year) from 5G base station investment and financial business expansion
- Continued downward pressure on mobile ARPU from the ongoing spread of low-priced rate plans (such as irumo)
- Continuing structural decline in fixed-line voice-related service revenue
- Increase in revenue-linked costs and regulatory risk associated with expansion of the Smart Life Business (finance and payments)
