Dongguan Eontec Co., Ltd. (300328.SZ) - BCG Matrix Analysis: Cash Cows

Cash Cows

PRECISION ALUMINUM ALLOY DIE CASTING PRODUCTS: The traditional aluminum die-casting business remains a stable foundation contributing 18% of total company revenue (FY2025 revenue contribution: RMB 540 million of an estimated RMB 3.0 billion consolidated revenue). The mature market exhibits a low CAGR of 4% reflecting saturation in general industrial machinery. Eontec maintains a strong 15% market share in the regional high-precision aluminum casting market, with gross margins steady at 22% (gross profit approx. RMB 118.8 million from this segment in FY2025). Segment EBITDA margin is approximately 14%; segment CAPEX requirement is low at 3% of segment revenue (approx. RMB 16.2 million annually), enabling high free cash flow generation (operating cash flow estimated RMB 75-90 million after working capital).

TELECOMMUNICATIONS INFRASTRUCTURE STRUCTURAL COMPONENTS: Structural parts for 5G and 6G base stations contribute 15% of the overall revenue stream in late 2025 (estimated revenue RMB 450 million).

Net margin for the segment is consistent at 12% (net income contribution approx. RMB 54 million), despite intense price competition and OEM cost pressures. Reinvestment needs are minimal due to largely fully depreciated plant; reported ROI for the segment exceeds 20% (return on segment capital employed), driven by low incremental CAPEX and stable order volumes.

TRADITIONAL SMARTPHONE INTERNAL STRUCTURAL FRAMES: Legacy metal frames for non-foldable smartphones account for 10% of current revenue (approx. RMB 300 million). The market growth rate is negligible at 1% and highly commoditized. Eontec's market share in this segment is approximately 7% domestically. Operating margins are around 15% (operating profit ~RMB 45 million), and inventory turnover for standardized parts remains high at 8x per year, supporting strong liquidity and quick conversion of working capital into cash.

Key cash-generation characteristics across these cash cow segments:

• Combined revenue contribution: 43% of total (approx. RMB 1,290 million of FY2025 est.).
• Weighted average market growth: ~2.33% (low-growth portfolio).
• Weighted average company market share across segments: ~10.7%.
• Weighted average gross/net margins supportive of internal funding: gross ~19%, net/operating ~13%.
• Low average CAPEX intensity (~3% of segment revenue) enabling sustained free cash flow to fund stars and potential question marks.

Dongguan Eontec Co., Ltd. (300328.SZ) - BCG Matrix Analysis: Dogs

Dogs - LOW END ZINC ALLOY DIE CASTING PARTS: The low-end zinc alloy die casting unit now contributes 3% of consolidated revenue. Market volume is contracting at -5% CAGR as OEMs adopt lighter materials (magnesium, aluminum, engineered plastics). Eontec's estimated share in this fragmented commodity market is under 2%. Gross margin has compressed to 8% due to a 12% year-on-year raw material cost increase and persistent overcapacity in regional foundries. Capital expenditures have been halted for this line; management targets full divestment by 2026 if margins and volumes do not recover.

Dogs - LEGACY PLASTIC INJECTION MOLDING SERVICES: Legacy plastic injection molding for older consumer electronics represents approximately 2% of revenue and faces a -10% annual market shrinkage as product lifecycles shorten and customers migrate to metal/advanced polymer solutions. Eontec's share is ~1% as strategic focus has shifted to advanced metal alloys and high-precision components. Reported ROI for this segment is 2%; net margins have fallen to ~5% after elevated maintenance and tooling refurbishment costs for aging machines.

Dogs - DISCONTINUED TELECOM HARDWARE REPLACEMENT PARTS: Replacement parts for obsolete telecom equipment now generate roughly 1% of revenue. The addressable market is contracting at -15% per year as carriers and enterprise customers upgrade to new standards; Eontec's market share is negligible. The unit is operating at near break-even with a 1% margin, primarily maintained by sporadic aftermarket orders. Inventory and warehouse space tied to this line represent an opportunity cost versus potential reallocation to high-growth liquid metal production.

Combined Dogs - Portfolio snapshot and short-term financial impact:

Operational and financial implications:

• Free up 6-8% of floor/warehouse capacity by 2026 through divestment or shutdown of Dogs segments.
• Reduce working capital tied to slow-moving inventory (estimated RMB 40-60 million) by repurposing or selling stock.
• Eliminate low-return fixed costs to improve consolidated EBITDA margin by an estimated 120-180 bps over two years.
• Redirect saved CAPEX and OPEX toward liquid metal and advanced alloy lines with target IRR >20%.
• Explore selective asset sales or third-party partnerships to accelerate exit while minimizing severance and shutdown costs.
