Investment Thesis
Pure-play sovereign-AI infrastructure parent. NTT owns the only Digital-Agency-trialed Japanese LLM ('tsuzumi 2', selected for the 'Government AI / Gennai' pilot from FY2026), runs Japan's largest domestic data-center fleet (~300MW today, target 1GW by FY2033 via AIOWN), and after the ¥2.4T NTT Data buyout (Sept 2025) consolidates the entire sovereign-cloud + sovereign-LLM stack inside one listed parent. PE ~11.7-12.1x, P/B 1.32x, EV/EBITDA 7.86x, 3.46% dividend — the cheapest large-cap pure exposure to Japan's ¥1T/5yr sovereign-AI subsidy program.
Risk
1) Telecom domestic ARPU pressure (mobile competition + Feb 2026 profit-forecast cut on weaker global conditions) caps headline earnings growth. 2) ¥16.4B/$2.4T NTT Data buyout has lifted leverage and consumes free-cash flow. 3) AIOWN 1GW target is a 7-year buildout — sovereign-AI revenue contribution still <5% of group EBITDA in FY2026. 4) tsuzumi 2 is competitive with foreign frontier LLMs only in Japanese and only in low-resource deployments — not a frontier model.
Monitoring Trigger
If Digital Agency Gennai pilot converts to multi-year contract → ADD to 9%. If AIOWN Phase-1 (>500MW) commissioning ahead of schedule → ADD to 9%. If FY2026 group EBIT growth <2% → HOLD. If telecom segment margin compression accelerates → TRIM to 5%.
