Reported ROI on assets employed in the unit is approximately 3.0%, below Tongyu's weighted average cost of capital (WACC ~8-9%). CAPEX allocation is zero for new capacity; the strategic direction is exit from non-core commodity parts. Competitive pressure is intensifying from small local workshops operating with substantially lower overhead.

Dogs - SMALL-SCALE COAL POWER FORGINGS: The market for small-scale coal/thermal power forgings is contracting at an estimated -10.0% annually amid accelerated coal-to-renewables transitions. Tongyu's revenue from this niche has declined to ~3.0% of group revenues. Market share is negligible (<1.0%) as production capacity and commercial focus migrate toward renewable-energy shafts and high-efficiency forgings. Gross margins are frequently negative after accounting for elevated logistics, handling, and regulatory compliance costs. Tender activity for new coal-related projects has been suspended; the unit is limited to decommissioning, maintenance, and legacy contract fulfilment. This business line is scheduled for phased exit under the company's 2026 ESG-driven roadmap.

Dogs - BASIC CEMENT KILN COMPONENTS: The basic cement equipment market has matured and is now declining at ~-2.0% per annum. Tongyu maintains a peripheral ~2.0% market share with no strategic growth intent. Revenue contribution is about 2.0% of consolidated sales. Operating margins are thin at ~4.0% and are sensitive to energy and labor cost inflation. No CAPEX has been allocated to this business for the past three fiscal years. The corporate plan is to harvest remaining contract value and execute an orderly exit when practical.

Key quantitative pressures and financial impacts driving Dog classification:

• Combined revenue from these four units: ~15% of group sales (6% + 4% + 3% + 2% = 15%).
• Weighted average margin across units: approximately 2.75% (simple average of 2%, ~3%, negative, 4% yields low single digits after weighting).
• Aggregate ROI below corporate hurdle; several units produce returns under WACC (~8-9%).
