Key Star Metrics Summary

Tongwei Co.,Ltd (600438.SS) - BCG Matrix Analysis: Cash Cows

GLOBAL LEADERSHIP IN HIGH PURITY CRYSTALLINE SILICON: Tongwei remains the global cost leader in polysilicon production with a total annual capacity of 850,000 metric tons as of December 2025. This segment provides the primary cash flow for the group, contributing 38 percent of total annual revenue. While the market growth rate has stabilized at 6 percent, Tongwei maintains a dominant 26 percent share of the global high purity silicon market. Production costs have been driven down to below 38,000 RMB per ton, ensuring a robust gross margin of 24 percent even during price troughs. The segment requires relatively low maintenance CAPEX of 2.5 billion RMB compared to its massive cash generation. This business unit serves as the financial foundation, providing the liquidity needed to fund the expansion of the Star and Question Mark segments.

Implications and operational notes for polysilicon:

• High cash conversion: low CAPEX intensity vs. revenue contribution enables funding of growth segments.
• Sensitivity to global polysilicon price cycles despite cost leadership; margins resilient but not immune.
• Ongoing focus on cost control, operational efficiency and scale to defend 26% market share.

STABLE MARKET POSITION IN AQUATIC FEED PRODUCTS: The traditional core business of aquatic feed continues to deliver steady performance with annual sales volumes exceeding 7.5 million tons. This mature segment operates in a market growing at a modest 4 percent annually but provides consistent cash distributions. Tongwei maintains its position as the domestic leader with an 18 percent market share in the high end aquatic feed category. The segment contributes approximately 22 percent to the total corporate revenue with a stable net profit margin of 5 percent. Capital expenditure is strictly controlled at 1.2 billion RMB, focusing primarily on logistics and supply chain optimization rather than capacity expansion. The return on equity for the feed division remains a reliable 15 percent, supporting the company's overall dividend policy.

Operational characteristics and risk considerations for feed:

• Predictable cash flows due to mature demand and scale-driven distribution networks.
• Limited upside in growth-strategy centered on margin protection, logistics efficiency, and product mix improvement.
• Exposure to raw material price volatility (fishmeal, soybean) requiring hedging and procurement optimization.

MATURE PV POWER GENERATION ASSETS: The portfolio of completed and grid connected solar power plants acts as a reliable cash generator with 4.2 gigawatts of mature assets. These assets benefit from long term power purchase agreements that guarantee revenue for the next 15 to 20 years. The segment growth is low at 3 percent as the company shifts focus toward new installations, but existing plants require minimal operational expenditure. Operating margins for these mature assets are high, often exceeding 45 percent due to the absence of fuel costs and low staffing requirements. This segment accounts for 5 percent of total revenue but a disproportionately higher share of net operating cash flow. The debt to equity ratio for these specific assets has been reduced to 55 percent, further improving the net cash contribution to the parent company.

Key operational points for PV generation:

• High visibility cash flows via long-term PPAs support credit profile and group liquidity.
• Low OPEX and sustained operating margins make assets ideal for deleveraging and dividend support.
• Limited organic growth from mature assets; reinvestment prioritized in higher-return opportunities or balance sheet repair.

Tongwei Co.,Ltd (600438.SS) - BCG Matrix Analysis: Question Marks

Question Marks

ENTRY INTO LARGE SCALE ENERGY STORAGE SYSTEMS: Tongwei launched an energy storage division targeting 10 GWh of battery systems production by 2025. The global energy storage market is expanding at an estimated CAGR of 45% annually. Tongwei's current global market share in stationary storage is below 2%, classifying this initiative as a Question Mark: high market growth, low relative market share. Initial gross margins are thin at 7% due to aggressive pricing and customer acquisition spending. Capital expenditures specifically for establishing LFP (lithium iron phosphate) production lines totaled approximately RMB 6.0 billion in 2025. The unit economics and payback profile depend heavily on integration with Tongwei's solar PV installations and downstream EPC and O&M services to capture bundled sales.

Key strategic considerations for the energy storage Question Mark include supply chain scale-up, cost curve trajectory for LFP cells, warranty and lifecycle performance, and channel overlap with established battery OEMs. Conversion to a Star requires rapid market share gain or margin expansion through vertical integration.
