Sumitomo Metal Mining (5713.T): Resources Anchor Earnings; Upside Linked to Copper & Gold
- Earnings re-based higher: FY2025–27 EPS upgraded ~20%, driven by copper and gold prices; resource earnings dominate while smelting volatility remains largely accounting-driven.
- Valuation near fair value: At ~¥6,000, SMM trades around mid-cycle value; upside depends on sustained copper/gold strength rather than multiple expansion.
- Downside cushioned: Strong balance sheet and ~2× FCF dividend cover limit downside, with pullbacks offering better entry than chasing spot-driven rallies.

- The company is strategically positioned to benefit from the increasing geopolitical importance of tungsten and the desire of Western economies to secure supply chains for critical minerals outside of China.
- While the long-term outlook is promising, Almonty currently faces financial pressures from its development activities, reflected in its unprofitability and negative cash flow, and is subject to significant execution risk as it ramps up production at Sangdong.
