Jiangsu Sanfame Polyester Material Co.,Ltd. (600370.SS) - BCG Matrix Analysis: Cash Cows

Cash Cows

Purified Terephthalic Acid (PTA) production functions as a primary cash cow via upstream integration. Sanfame's PTA production base capacity is approximately 1.8 million tonnes per annum, supporting internal polyester chip feedstock needs and enabling scale-driven cost advantages versus smaller, obsolete competitors. In 2025 domestic PTA capacity reached 86.02 million tonnes at the start of the year while industry capacity growth was about 9.9% for the year; Sanfame's integrated "PTA-bottle-grade polyester" chain sustains utilization near the industry average of 82%, delivering steady margins and predictable free cash flow. The PTA segment underpins the group's total trailing twelve months (TTM) revenue of approximately CNY 21.85 billion as of late 2025 and contributes materially to operational cash generation even amid market supply surplus.

The conventional polyester staple fiber (PSF) business remains a cash-generating, low-investment unit. Sanfame's PSF annual production capacity exceeds 220,000 tonnes, operating in a mature textile segment with a modest projected CAGR of -0.4%. Global PSF market size exceeded USD 36 billion in 2025, with China capturing roughly 39.2% of demand. Sanfame's PSF operations report a projected net profit margin around 8.5%, supported by the established "Cuiyu" trademark and an established distribution footprint across 105 countries and regions. Low incremental CAPEX requirements for PSF lines enable redeployment of cash into higher-return R&D or upstream efficiency projects while maintaining stable cash inflows.

• PSF strengths: branded recognition (Cuiyu), broad export footprint (105 countries), low maintenance CAPEX.
• PTA strengths: large-scale capacity (1.8 Mtpa), high utilization (~82%), vertical integration driving cost advantage.
• Thermoelectric strengths: regulated pricing, steady baseload returns, internal energy cost offset for industrial park employing 7,000+ staff.

The thermoelectric power business serves as a stable utility cash cow. It supplies electricity and steam to Sanfame's industrial park and sells surplus power to the local grid, creating a non-cyclical income stream with minimal sales/marketing spend. The segment's predictable returns stem from regulated utility pricing and internal synergies (reduced plant energy costs, improved overall asset utilization). By December 2025, this business continued to deliver a steady return on invested capital, providing balance-sheet stability and cushioning polyester margin volatility.

Key financial and operational indicators across cash cow segments emphasize predictability and internal support for higher-growth initiatives: substantial PTA capacity (1.8 Mtpa) with near-industry utilization, PSF capacity >220 ktpa with ~8.5% net margin, thermoelectric operations providing regulated, low-variance returns and enabling cost savings for the group's 7,000+ employee base.

Jiangsu Sanfame Polyester Material Co.,Ltd. (600370.SS) - BCG Matrix Analysis: Dogs

Section: Dogs - legacy low-growth, low-share assets presenting divestment/reshaping pressure.

Traditional cotton yarn and textile manufacturing at Sanfame has contracted sharply as the group pivoted toward polyester materials. Revenue contribution from cotton yarn, denim and related textile operations fell from 18.4% of consolidated revenue in 2019 to 6.2% in FY2024. In 1H2025 the segment accounted for 4.8% of revenue. Domestic demand stagnation, rising labor costs and relocation of apparel/textile production to Southeast Asia have driven segment growth to near-zero or negative levels (estimated CAGR -2.1% 2020-2025). Relative market share vs. specialized textile giants is negligible (estimated <1%). Return on Capital Employed (ROCE) for the traditional textile division declined from 8.3% in 2020 to 2.1% in 2024.

Legacy chemical fiber processing units with older, less efficient equipment are another set of 'Dog' assets. These older lines-predating the German Neumag/Barmag installations-consume materially higher electricity and steam per tonne of product. Sanfame reported an internal target to reduce energy intensity by 20% group-wide since 2020; older units remain 15-30% above the company average energy consumption per tonne. With domestic polyester chip processing margins down ~14% YoY in early 2025, legacy processing units have margins close to breakeven and contributed less than 5% to consolidated net income in FY2024.

Operational and strategic implications of these Dog assets are reflected in capital allocation and capacity management decisions. Management has indicated an increasing focus on rationalizing low-return factories and reallocating capital to core polyester upstream and specialty chemical segments, consistent with the stated ambition to become a 'world-class chemical enterprise.' Divestment, idling or technological upgrades of these underperforming assets are probabilistic responses.

• Likely actions: sale or closure of select textile plants; mothballing or phased shutdown of inefficient fiber lines.
• Capex reallocation: expected shift of >60% of incremental capex (2025-2027) toward polyester chip, specialty polymer and advanced spinning technology.
• Short-term impact: one-off impairment charges and restructuring costs estimated at CNY 120-220 million tied to 'Dog' asset write-downs (management guidance range).

Quantified risk exposure to continued low-margin legacy operations if not acted upon includes:
