KDDI reported strong financial and operational growth in Q1-2026 as the telecom operator accelerated investments in AI infrastructure, broadband, 5G, IoT, cloud, and enterprise digital transformation services.
The company’s latest financial results and investor presentations highlighted rising revenue, improving ARPU, subscriber growth, expanding digital businesses, disciplined Capex management, and an aggressive long-term AI strategy centered on its “Digital data x AI” vision.
KDDI generated operating revenue of ¥6.07 trillion in fiscal year 2026, representing 4.1 percent year-on-year growth, while operating income increased 1.1 percent to ¥1.09 trillion. Net profit rose 7.9 percent to ¥707.1 billion, and EBITDA increased 2.5 percent to ¥1.85 trillion.
The company said underlying operating income, excluding one-time impacts, increased 6 percent to ¥1.16 trillion, supported by growth in mobile services, broadband, digital transformation, finance, energy, and AI-driven enterprise businesses.
The operator had previously reported revenue of ¥5.84 trillion in fiscal year 2025, up 2.4 percent year-on-year, with operating income increasing 19.2 percent to ¥1.09 trillion. The company attributed growth to rising communications ARPU, expansion in finance and energy businesses, Lawson-related synergies, and stronger digital transformation demand.
KDDI’s mobile business continued to strengthen through higher ARPU, premium service adoption, and subscriber gains. During Q1 fiscal 2026, mobile ARPU increased ¥60 year-on-year to ¥4,340, while smartphone subscriptions increased by 450,000. By the end of March 2026, smartphone subscriptions reached 33.23 million and total mobile subscribers exceeded 70.3 million contracts. Mobile ARPU later increased ¥100 year-on-year to ¥4,440.
The company said its multi-brand strategy involving au, UQ mobile, and povo improved customer retention and reduced churn while supporting migration toward higher-value unlimited data plans. New services such as au 5G Fast Lane, au Starlink Direct, and unlimited overseas data services also contributed to higher customer engagement and data consumption.
Broadband and enterprise connectivity remained growth engines for KDDI. The company expanded its fiber, 5G standalone infrastructure, IoT connectivity, and enterprise cloud solutions. IoT-related services generated ¥122 billion in first-half revenue, increasing around 10 percent year-on-year. Total IoT connections increased 19.5 percent to 53.2 million globally, supported by growth in connected mobility, industrial IoT, and smart infrastructure deployments.
KDDI is aggressively expanding its AI and digital infrastructure strategy. The company is building AI data centers, GPU cloud infrastructure, sovereign cloud platforms, and AI-enabled enterprise services to support Japan’s growing digital economy. Under its “Digital data x AI” initiative, KDDI is integrating AI agents, robotics, digital twins, smart mobility, and advanced analytics into telecom and enterprise operations.
A major pillar of the strategy is the “Takanawa model,” which combines telecommunications infrastructure, AI, cloud, digital twins, and real-world operational data to create smart city and enterprise ecosystems. KDDI plans to expand this model nationwide across enterprises, municipalities, industrial sectors, and public infrastructure projects.
Enterprise and business services continued delivering strong growth, particularly in cloud, cybersecurity, data centers, IoT, and digital transformation. KDDI forecast business services revenue of ¥1.59 trillion with operating income projected to increase 16.7 percent to ¥272 billion. The operator said AI-enabled BPO services, cybersecurity offerings, and enterprise cloud infrastructure are becoming key profit contributors.
Generative AI has become increasingly important across KDDI’s operations. The company is integrating AI into contact center platforms, digital BPO operations, customer support, financial monitoring systems, and enterprise automation services. KDDI said AI-driven workflow optimization and automation are improving operational efficiency, reducing costs, and enhancing customer experience.
Capital expenditure remained focused on long-term infrastructure modernization. KDDI reported Capex of ¥678.9 billion, down ¥70.4 billion year-on-year due to reduced spending after previous investments in Canadian data center assets. However, the company continues prioritizing investments in 5G standalone networks, broadband expansion, AI infrastructure, GPU clusters, enterprise ICT platforms, and cloud capabilities.
On the Opex side, KDDI emphasized operational efficiency through automation, AI integration, digital governance systems, and technology optimization. The operator is using AI-based financial alert systems, intelligent automation, and digital governance platforms to strengthen operational control while improving profitability.
KDDI’s digital transformation strategy also extends into finance, energy, commerce, and smart infrastructure. The company is leveraging its telecom ecosystem to expand digital payment services, fintech, smart energy platforms, and integrated digital lifestyle offerings to improve customer lifetime value and cross-selling opportunities.
Looking ahead, KDDI forecasts fiscal 2027 operating revenue of ¥6.41 trillion, representing 5.6 percent growth, while adjusted operating income is expected to rise 5 percent to ¥1.21 trillion. Adjusted EBITDA is projected to increase to ¥1.94 trillion.
The company’s mid-term strategy focuses on achieving sustainable profit growth through telecom expansion, broadband leadership, AI monetization, enterprise digital transformation, cloud infrastructure, and next-generation digital services. KDDI aims to maintain approximately 5 percent operating profit CAGR while balancing disciplined capital allocation, network investment, shareholder returns, and AI-driven innovation.
