• Market growth: -5.0% (declining due to fleet retirements and avionics digitization).
• Company share: 15% in a shrinking niche; absolute shipments down ~12% YoY.
• Revenue: <2% of total; low absolute contribution limits cross-subsidization capacity.
• Margins: Gross margin compressed to 10% due to low volumes and high tooling overhead; contribution margin negative after overhead allocations.
• CAPEX: Zero planned for 2026; decommissioning and inventory liquidation underway.
• Strategic stance: Formal phase-out program with vendor buyback and customer transition support.

Basic metal casting for third parties - metrics and context:

• Market growth: 2.0% (commoditized, price-sensitive).
• Company share: 1% regional share; facility utilization typically <60%.
• Revenue: 1.5% of consolidated revenue; highly variable monthly order book.
• Profitability: Break-even net margin; intermittent small losses after fixed cost allocations.
• ROI: ~3.0%; below internal hurdle rates (target ROI 10%+ for discretionary capital).
• Resource allocation: Skilled labor and maintenance budgets trimmed; production capacity redirected toward aerospace lines during peak demand.

Small scale automotive turbocharger parts - metrics and context:

• Market growth: 3.0% (long-term downside risk from EV adoption; internal demand forecast declines from 2030 onward).
• Company share: <2%; limited OEM qualifications and low bargaining power.
• Revenue: 1.0% of total; single-digit contribution insufficient to sustain advanced engineering support.
• Margins and funding: Operating margin 6%; technical support cost burdens; investment frozen at RMB 15 million for past 12 months.
• Strategic options: Candidate for restructuring, JV with tier-1 auto supplier, or full exit by end-2026 depending on bid/offer outcomes and potential write-downs.

Operational and financial implications for the portfolio:

• Aggregate revenue from Dogs: ~7.5% of total 2025 revenue (sum of segments: 3.0% + <2.0% + 1.5% + 1.0% ≈ 7.5%).
• Weighted average operating margin across these units: approximately 6% (drags consolidated margin by ~0.45 pp assuming 7.5% revenue weight).
• Combined ROI weighted average near 3.1%-well below corporate hurdle rates; capital deployed here demonstrates negative opportunity cost relative to aerospace core investments.
• CAPEX posture: maintenance-only or frozen across segments reduces cash burn but raises obsolescence and long-term exit costs (decommissioning, employee severance, environmental remediation potential for casting foundry).

Recommended immediate actions under consideration (operationally actionable metrics included):

• Pursue divestiture offers for non aero industrial pumps: target sale price threshold = 2x EBITDA; current EBITDA margin ~5% implies minimal proceeds but removes maintenance CAPEX and frees working capital.
• Execute controlled phase-out of analog controllers: accelerate inventory liquidation with targeted salvage recovery goals ≥60% of book value for obsolete tooling.
• Assess third-party tolling or lease-out options for casting foundry to avoid fixed-cost drag; target utilization increase to ≥80% if retained, or closure if utilization cannot exceed 65% within 12 months.
• For automotive turbo parts, seek strategic partner or buyer; set decision trigger: if order pipeline <6 months of confirmed demand or no JV terms within Q2 2026, initiate exit to avoid further RMB 15m capital stagnation and ongoing support costs.
