Investment Thesis
Japan's leading water and environmental infrastructure EPC company with a compounding overseas growth engine. FY2026: revenue ¥209.8B (+17.2%), operating profit ¥12.9B (+21.2%), ROE 9.1% (above TSE 8% target). Overseas business grew +50.4% YoY — Japan's water infrastructure expertise is being exported to Southeast Asia and Middle East at scale. PE 13.2x and forward PE 11.8x are cheap for a high-quality infrastructure franchise with recurring service revenue. Defensive business model: municipal water utilities sign multi-decade operating contracts.
Risk
1) Japan government water capex concentration — ~40-50% revenue from domestic municipalities; budget constraints risk. 2) Stock up 2.5x from 52-week low — valuation risk if overseas growth slows. 3) OP margin 5.9% is thin — project execution risk can compress margins sharply. 4) Currency risk on overseas revenue if yen strengthens significantly.
Monitoring Trigger
H1 FY2027 results (Nov 2026): if overseas revenue growth slows below 25% for 2 consecutive halves, TRIM. If overseas revenue mix exceeds 35% of total, RE-RATE higher (less domestic government dependency). PE expanding above 20x without revenue acceleration → TRIM.
