NTT Earnings: Forecast for 5% Decline in FY2026 Net Profit Due to Docomo's Falling Market Share
⚡ What Happened
NTT announced that its full-year net profit for FY2026 is expected to decline by more than 5% year-over-year. The primary cause is deteriorating earnings due to falling market share at its subsidiary NTT Docomo in the mobile phone market. This marks a turning point where the structural intensification of competition in Japan's domestic telecommunications market has begun directly impacting the profitability of the entire NTT Group.
NTT's profit decline forecast is a manifestation of structural changes in Japan's telecommunications industry. Since the Suga administration's pressure to lower mobile phone rates in 2020, carriers have been forced into price competition. Docomo has been squeezed on both subscriber numbers and ARPU due to Rakuten Mobile's market entry, MVNO expansion, and self-cannibalization from its own low-cost plans such as ahamo. Combined with the NTT Act reform debate and massive investment in the IOWN initiative, the balance between short-term earnings and long-term investment is being questioned. This profit decline forecast once again highlights the growth ceiling for the telecommunications business alone, and the pace of transition to non-telecom areas (data centers, global IT, Smart Life) will determine future stock valuations.
🔍 The timing of NTT's announcement of a profit decline also serves as a message to the government and ruling party amid ongoing political discussions about NTT Act reform and full privatization. It is an implicit signal that "growth investment is difficult without deregulation." Furthermore, Docomo's declining market share is a structural problem emerging as Rakuten Mobile approaches profitability, and the 5% decline figure is likely a conservative guidance already priced into the market. Management should be seen as intentionally setting a "low bar" to leave room for upward revisions during the fiscal year.

🔮 Next Scenarios
🎯 Incentive Map
| Player | True Incentive | Underlying Vulnerability | Expected Action |
|---|---|---|---|
| NTT Management (President Akira Shimada) | Wants to emphasize the severity of regulatory costs and the competitive environment to steer NTT Act reform in its favor | Caught between maintaining government relations and shareholder returns. Fixated on the long-held aspiration of NTT Act reform | Issue conservative guidance while retaining shareholders through share buybacks and dividend increases. Continue appealing to the government that 'investment is difficult without deregulation' |
| Rakuten Mobile (Hiroshi Mikitani) | Wants to achieve profitability to restore credibility for the Rakuten Group as a whole and reduce financing costs | Massive interest-bearing debt and credit rating downgrades. Group survival is at risk without telecom business profitability | Continue aggressive pricing and point reward campaigns to accelerate market share gains from Docomo. Expand offensive into the enterprise segment |
| Ministry of Internal Affairs / Government | Balancing the maintenance of lower telecom rates with strengthening international competitiveness through NTT Act reform | Full privatization of NTT involves a trade-off between fiscal revenue (dividends and share sale proceeds) and national security | Advance NTT Act reform discussions incrementally while maintaining a cautious stance on full privatization. Keep competition policy at status quo |
⚠️ Pre-Mortem — Conditions Under Which This Prediction Fails
- If the profit decline is smaller than market expectations and already priced in, and the stock price rises instead due to shareholder return measures such as share buybacks, the NO prediction is correct but the underlying premise differs
- If a macro event causing a broad Japanese market selloff occurs during the same period (e.g., a sharp rise in US interest rates or geopolitical risk), resulting in a 3% decline driven by market correlation rather than NTT-specific factors
- If detailed earnings figures such as Docomo's net subscriber losses come in worse than expected, triggering a wave of analyst target price downgrades
Fear-Setting / When this prediction fails
- This probability fails if a concurrent macro selloff (e.g., BOJ policy surprise or US rate shock) drags NTT below 3% regardless of earnings quality.
- This probability fails if NTT reveals a significant downward revision in docomo subscriber numbers beyond consensus, triggering analyst downgrades.
- This probability fails if NTT announces a large unexpected capex increase for IOWN or data centers that spooks income-focused investors.
Hit Condition: Resolves as HIT if NTT's stock price (9432) falls 3% or more from the closing price on the day before the earnings announcement by May 15, 2026
Resolution Date: 2026-05-15
