Legacy CNC machine tool division: The legacy CNC machine tool product line now contributes 5.5% of group revenue and operates in a declining market (-2.1% CAGR) as customers migrate to integrated smart systems. Tianma's relative market share in this commoditized segment has fallen to 4.5% amid intense price competition from regional low-cost players. Operating margins have compressed to 7.8%, only marginally above the company's weighted average cost of capital (WACC). Capital expenditure allocated to this division has been cut to 1.5% of group CAPEX to conserve cash for higher-growth units, and fixed-cost absorption issues are increasing break-even pressure.

Implications and tactical considerations for the CNC division:

• Pursue orderly wind-down or selective carve-out of non-core product lines to stem losses.
• Reallocate incremental R&D/CAPEX to integration projects (smart systems) or potential JV partners with complementary tech.
• Implement cost-to-serve reductions and rationalize SKUs to improve cash generation while avoiding large new investments.

Low-end automotive bearing series (ICE vehicles): The low-end ICE bearing line faces structural decline as the automotive industry pivots to NEVs. Market growth has slowed to 1.2% and demand contraction is accelerating in developed markets. Tianma's market share is 6.8% after a deliberate strategic shift toward NEV-focused offerings. Gross margins have dropped to 12.5% due to higher raw material costs (steel, alloy inputs up 8-12% year-over-year) and falling volumes. ROI for the segment is 5.4%, below the company's hurdle rate, positioning it as a candidate for phase-out or selective divestment within a 24-36 month window.

Operational actions and risks:

• Accelerate product migration incentives for key OEM customers toward NEV bearing solutions to preserve channel relationships.

Textile machinery bearing products: The textile bearing segment shows near-zero expansion with a 2025 market growth rate of 0.5%. Tianma holds a minor 3.5% market share in a niche dominated by specialized local manufacturers. Revenue from this segment has declined to 3.0% of total group revenue over the last year. Gross margins are constrained at 10.2% owing to low technical complexity and intense price sensitivity. R&D for this line has been halted entirely to minimize losses and redeploy resources.

Recommended management posture:

• Maintain minimum working capital and supplier terms to keep the line cash-neutral while exploring exit partners or licensing.
• Pursue selective aftermarket/service contracts to monetize installed base without new product investment.
• Evaluate one-time write-down versus continued low-level production based on long-tail service demand analytics.

Basic construction equipment bearing line: This product line underperforms amid a slowdown in traditional infrastructure projects; market growth is 1.8%. Tianma's market share has been static at 5.2% for three consecutive years. Operating margin sits at 9.5% and ROI is below 6%, failing to meet the internal hurdle rate for new capital deployment. The division requires continuous maintenance of aging production assets, driving up unit costs. Management has classified this unit for 'harvesting' to extract residual cash flows without committing fresh capital.

Harvest strategy and execution priorities:

• Maximize free cash flow through pricing discipline and tightening of working capital terms.
• Decommission or consolidate inefficient production lines to reduce fixed-cost burden.
• Prepare exit scenarios (asset sale, licensing of production) to convert marginal assets into liquidity if market conditions worsen.
