ECO FRIENDLY BIODEGRADABLE PACKAGING MATERIALS: This emerging segment targets a global market growing at a rapid 22% p.a. As of December 2025 it contributes 6% to Sunglow's total revenue (RMB 420 million of RMB 7.0 billion consolidated revenue). Domestic biodegradable materials market share for Sunglow stands at 3% (company-estimated domestic addressable market RMB 14.0 billion). The company has allocated 35% of its R&D budget to biodegradable development (R&D budget total RMB 120 million; allocation RMB 42 million). Operating margins for this unit are currently 8%, compressed by initial material costs and low-scale manufacturing; unit-level operating profit is approximately RMB 33.6 million annually. Unit capital intensity remains moderate with current segment-specific CAPEX at RMB 65 million (capex/revenue ratio ~15.5% for the segment). Forecast: market CAGR 22% implies a potential segment revenue of ~RMB 844 million for Sunglow by 2028 if market share rises to 6%.

SMART PACKAGING WITH IOT INTEGRATION: The intelligent packaging market with tracking sensors is expanding at 25% p.a. This business unit accounted for less than 4% of Sunglow's total corporate revenue as of December 2025 (estimated RMB 280 million).

LOW VALUE PLASTIC PROTECTIVE WRAPPING

This legacy product line now contributes 3% of Sunglow's total revenue. Market growth for non-recyclable plastic films has slowed to +1% annually due to stringent environmental regulations and substitution by recyclable/biodegradable alternatives. Sunglow's relative market share in this fragmented, commoditized segment is approximately 2%. Gross margins have compressed to 6% (down from historical levels of ~12-15%). There is zero planned CAPEX for FY2026 for this segment. Competitive pricing pressure has driven price erosion of ~8% year-over-year on average across suppliers in the last 24 months.

STANDARD METAL FASTENING AND HARDWARE COMPONENTS

This ancillary unit accounts for 2% of group revenue. The addressable market is contracting at -2% annually as integrated packaging designs and adhesive technologies reduce demand for separate metal fasteners. Sunglow's market share in the industrial hardware supply chain is ~1%. Return on investment for the division is currently 4%. Management has classified this unit as a candidate for divestment, citing strategic misalignment with the company's sustainability targets and low strategic priority. Planned R&D and capital allocation to this division are negligible.

Comparative metrics for the two Dog segments:

Key operational and financial implications

• Cash generation: Combined contribution is ~5% of revenue and contributes negligible free cash flow after margin compression.
• Capital allocation: Zero planned CAPEX for plastic wrapping; negligible capital for hardware - signalling deprioritization.
• Profitability risk: Low gross margins (6%) and low RoI (4%) increase the cost of holding these assets on the balance sheet.
• Regulatory exposure: Non-recyclable plastics face escalating compliance costs, potential bans, and rising disposal fees.
• Strategic fit: Both units conflict with Sunglow's stated move toward sustainable, recyclable packaging solutions.

Potential tactical options under consideration by management

• Divestiture or asset sale of the metal fasteners unit given minimal strategic synergy and low RoI.
• Phase-out or closedown of non-recyclable plastic film SKUs coupled with inventory liquidation to minimize carrying costs.
• Selective price discipline or volume reductions to stem margin erosion while avoiding further working capital drain.
• Reallocate resources and CAPEX toward higher-growth recyclable film and sustainable packaging R&D.
• Negotiate supplier consolidation or exit agreements to reduce fixed costs and contract liabilities tied to these lines.
