Sunstone Development Co., Ltd. (603612.SS): Mission and Values

• Vertical integration: the business controls procurement of feedstock (primarily imported petroleum coke), calcination, anode paste formulation, prebaking and shipment, minimizing third-party input and smoothing supply fluctuations.
• Feedstock importation: petroleum coke is imported in bulk and processed at Sunstone's integrated facilities to produce anode-grade calcined coke and paste.
• Manufacturing and quality assurance: automated paste mixing, shaping, vibro-compaction and prebaking lines with multi-stage quality inspection to meet customer specifications.
• Exports and market reach: finished prebaked anodes are exported to a diversified set of aluminum smelters across Asia, the Middle East and other regions, with export channels managed via the company's trade and logistics arm.
• R&D and sustainability focus: targeted R&D investments to reduce anode specific energy consumption, lower CO2 intensity in production and develop higher-density, longer-life anode products.
• Distribution network: coordinated warehousing, inland transportation and port logistics to ensure timely deliveries aligned with smelter production schedules.

• Product sales: primary revenue from sales of prebaked carbon anodes to aluminum smelters, invoiced per tonne with contracts often indexed to commodity input cost trends.
• Value-added grades: premium pricing for higher-performance anodes that offer lower specific consumption and longer life in smelting operations.
• By-product and intermediate sales: sales of calcined coke and other carbon intermediates to specialty carbon markets or internal use.
• Long-term supply contracts and spot sales mix: recurring revenue from multi-year offtake agreements plus opportunistic spot shipments to optimize utilization and margins.

• Raw material cost: petroleum coke import costs and freight are the largest single input, typically representing 30%-50% of COGS for anode producers.
• Energy and prebaking: energy (natural gas/electricity) for prebaking and calcination is a significant operating expense; energy-efficient ovens and process optimization reduce unit costs.
• Labor, maintenance and logistics: in-plant labor, equipment maintenance and port-to-customer logistics comprise the balance of operational costs.
• Margin drivers: product quality (lower specific consumption), long-term contracts, feedstock cost management and energy efficiency improvements drive gross and operating margins.

• Lowering specific anode consumption (SAC) for customers by developing denser, more conductive anode formulations.
• Reducing manufacturing energy intensity through improved prebaking furnace technology and waste-heat recovery.
• Minimizing environmental footprint via emissions control, dust capture, and optimized handling of volatile by-products from calcination.

• Procurement: strategic import contracts for petroleum coke to stabilize feedstock supply and manage price volatility.
• Internal processing: integrated calcination and paste formulation capacity reduces reliance on external suppliers and improves margin control.
• Distribution network: regional warehouses and partnerships with logistics providers to maintain on-time delivery and buffer inventory for export commitments.

• Primary customers: aluminum smelters seeking reliable anode supply with predictable quality and performance.
• Geographic markets: exports concentrated in nearby aluminum-producing regions while retaining domestic smelter contracts.
• Contract structure: mix of long-term supply agreements for baseline volumes and spot sales for incremental volumes and margin optimization.

Sunstone Development Co., Ltd. (603612.SS): How It Works

• Primary product: prebaked carbon anodes sold to aluminum smelters (primary domestic sales plus exports).
• Complementary product lines: battery anode materials, aluminum anode derivatives, and film capacitors for electronics and energy-storage markets.
• Raw-material trading: import and domestic sale of petroleum coke to secure feedstock and capture trading margins.
• Services & solutions: low-carbon service offerings and process optimization for customers to reduce CO2 intensity of smelting operations.
• Project JV income: equity and contractual revenue from large-scale energy-saving and carbon-material projects (e.g., 200,000 mt high-current-density project in Shanxi).

• Manufacturing → direct sales: Finished prebaked anodes produced at company-owned plants are sold under supply contracts to aluminum producers (spot and long-term agreements).
• Export channels: Logistics and export sales teams secure international buyers in Southeast Asia, the Middle East and other markets, invoiced in USD or CNY.
• Downstream materials & components: R&D and production lines convert carbon intermediates into battery anode precursors and film capacitors sold to battery/electronics makers.
• Trading & procurement: The company imports petroleum coke to stabilize raw-material supply and sells excess coke or intermediates into local markets for margin capture.
• Services & EPC: Low-carbon advisory, retrofitting and waste-heat power generation contracts deliver recurring and project-based service fees.
• JVs & project income: Equity share of profits or fixed-fee construction and operation contracts from joint venture projects (e.g., the Shanxi 200,000 mt project) provide non-operational revenue streams.

• Scale and utilization of prebaked anode production lines - higher capacity utilization lowers unit costs.
• Securing stable, cost-effective petroleum coke supply via imports to control feedstock volatility.
• Moving up the value chain into battery anode materials and film capacitors to capture higher margins.
• Expanding export volumes to diversify market risk and monetize global demand cycles.
• Monetizing low-carbon solutions and JV projects (like the 200,000 mt Shanxi energy-saving carbon material & waste-heat power generation project) to add project-based income and improve asset returns.
