NTT Advances IOWN and AI-Driven Infrastructure Despite Profit Decline in FY2025
NTT reported consolidated revenues of ¥13.70 trillion ($87.8 billion) for the fiscal year ended March 31, 2025, up 2.5% year over year, led by its Global Solutions segment. However, operating profit fell 14.2% to ¥1.65 trillion ($10.6 billion), and profit attributable to NTT declined 21.8% to ¥1.0 trillion ($6.4 billion) amid rising costs and strategic investments. The company forecasts a rebound in FY2026 with projected revenues of ¥14.19 trillion and a 7.3% increase in operating profit.
Technologically, NTT marked several industry-firsts with its IOWN (Innovative Optical and Wireless Network) initiative. In December 2024, NTT East and NTT West launched All-Photonics Network (APN) services offering up to 800 Gbps throughput, while international data centers in Japan, India, and Taiwan were interconnected over IOWN infrastructure. The firm expanded its generative AI efforts via the “tsuzumi” LLM, securing over 1,100 project engagements globally. NTT also reported a 1,000x improvement in optical quantum entanglement and breakthrough multi-core fiber designs supporting 10x transmission capacity.
NTT announced a ¥2.37 trillion ($15.5 billion) tender offer to acquire full ownership of NTT DATA Group, reinforcing its strategic role in global cloud and system integration markets. The company also unveiled plans to monetize data center assets through a Singapore-listed REIT and expects to book a ¥155.4 billion gain in FY2026. Capital expenditures totaled ¥2.13 trillion, supporting AI infrastructure, autonomous driving systems, sustainable food and energy innovation, and enhanced customer and employee experiences.
