Depreciation & amortization now represent 9% of operating costs as new data center modules come online. Debt-to-equity increased to 0.65 as infrastructure is financed, limiting M&A capacity and dividend flexibility.

Concentration in the Japanese domestic market increases exposure to domestic macro risks. ~92% of revenue derives from Japan; international revenue growth stagnated at 3% while domestic segments grew ~3x faster. Overseas subsidiaries in Asia and Europe contributed <5% of operating profit in 2025. Japan's working-age population is shrinking ~0.8% annually, constraining long-term domestic demand and limiting scale benefits versus multinational cloud providers.

Lengthy enterprise sales cycles and integration backlogs create revenue timing risk and higher customer acquisition costs. Average sales cycle for large-scale systems integration projects extended to 9 months. Customer acquisition costs for enterprise rose 15% as pre-sales complexity increased. Only 40% of initial digital transformation inquiries convert to long-term contracts within the first year. Backlog of uncompleted integration projects grew 12%, delaying revenue recognition and contributing to quarterly earnings volatility (standard deviation ~6% over last eight quarters).

• Structural cost disadvantages from third-party network dependence limit competitive price responses.
• Rising personnel and recruitment costs reduce operating leverage and compress net margins.
• Heavy CapEx and increased leverage constrain cash flexibility for M&A or shareholder returns.
• High domestic revenue concentration increases exposure to Japan-specific demographic and macro shocks.
• Prolonged sales cycles and backlog growth amplify revenue recognition risk and quarterly volatility.
