SunCoke Energy delivers metallurgical coke mainly via fenceline plants placed at or adjacent to steel mills for direct conveyor delivery; for non – adjacent customers it uses rail, barge, and the Convent Marine Terminal to link inland supply to seaborne markets.

Operating flow: coke from ovens to steel mills

SunCoke Energy operates coke batteries that convert metallurgical coal into hot coke and coke oven gas; hot coke moves by conveyor to adjacent steel customers or is cooled, handled and loaded for rail/barge shipment. Daily scheduling aligns oven pushes, rail blotter, and ship windows to keep throughput steady.

Product delivery: fenceline vs. logistics network

Fenceline operations enable direct conveyor delivery of hot coke and steam, cutting transport costs and handling. For distant mills and export, SunCoke Energy uses a rail fleet and barge services plus the Convent Marine Terminal for deep – water ship loading.

Production and sourcing: coal to coke

Coking blends are sourced from US and metallurgical coal suppliers and fed into byproduct and non – recovery coke ovens. The process produces coke oven gas and byproducts that SunCoke Energy captures for onsite energy or sales, supporting plant energy balance.

Channels and distribution: conveyors, rail, barge, export

Primary channel is fenceline conveyors into steel mill blast furnaces; secondary channels are unit trains and barges that connect to domestic mills and the Convent terminal for exports. Contracted rail slots and barge pooling reduce empty miles and cost per ton.

Key assets and partnerships: terminals, plants, logistics

Key assets include integrated coke plants, fenceline conveyors, a rail logistics network and the Convent Marine Terminal. Strategic partnerships with steelmakers, rail carriers, and marine operators enable high – throughput ship – loading and export of metallurgical coke.

What keeps it running day to day: throughput and contracts

Continuous oven pushes, real – time rail and barge scheduling, and long – term offtake contracts with steelmakers maintain steady cashflow. Operational KPIs focus on oven availability, conveyor uptime, and terminal ship – loading rates; in 2025 throughput targets and contract coverage drive margin stability.

Revenue flows mainly from long-term take-or-pay contracts that convert customer demand into predictable cash flows; fees for coke production and logistics are billed per ton with pass-through raw material charges protecting margins.

Take-or-Pay Long-Term Processing Contracts

SunCoke Energy earns most cash via 10-20 year take-or-pay contracts with steel mills that guarantee minimum volumes and steady fees for metallurgical coke production, securing revenue even if physical tonnage dips.

Fee-Based Logistics and Rail Services

Secondary revenues come from integrated coke supply chain services, including rail transport and storage logistics, where SunCoke charges steady service fees that complement processing margins.

Pass-Through Pricing and Cost Recovery

Pricing typically uses a pass-through model: customers pay the cost of coking coal and other variable inputs, while SunCoke bills a fixed processing fee per ton, insulating margins from commodity spikes.

Volume Guarantees as Primary Revenue Driver

The strongest revenue driver is the contractual minimums in take-or-pay agreements; with predictable volumes and fixed-fee-per-ton margins, SunCoke targets USD 250,000,000 to USD 270,000,000 Consolidated Adjusted EBITDA for fiscal 2025-2026.

Contracts also allocate byproduct credits (coke oven gas and byproducts) and occasional short-term spot sales; detailed commercial terms vary by plant location and joint ventures-see Customer Acquisition of SunCoke Energy Company for related commercial insights.

SunCoke Energy's model is sustainable where physical integration with steel mills and long-term take-or-pay contracts lock in demand, but it is fragile to steel industry downturns and regulatory emission pressures. Strengths include high utilization of 5.9 million tons domestic capacity and reliable product specs; dependencies include capital – intensive asset ties and contract expiries clustered in the late 2020s-2030s.

Why Physical Integration and Contract Structure Preserve Customer Relationships

Customers stay because switching is costly, assets are physically linked, and SunCoke Energy delivers both product reliability and decarbonization support that align with steel mill needs.

• Extreme switching costs: replacing an integrated coke plant requires multiyear permitting and capital expenditure often exceeding hundreds of millions per site.
• Contractual lock – in: take – or – pay and fixed – volume contracts extend into the late 2020s and 2030s, creating predictable revenue streams.
• High utilization: 5.9 million-ton domestic capacity running at elevated utilization in 2025-2026 sustains cash flow through steel cycles.
• Resilience vs exposure: structurally resilient to short cycles, exposed to long-term steel demand decline or stricter emissions rules.

Retention is driven by three concrete mechanisms: asset integration, commercial terms, and operational differentiation.

• Asset integration - Many SunCoke Energy plants are sited adjacent to or physically tied into steel mills, meaning feedstock handling, rail spurs, and heat-exchange connections are bespoke; removing that linkage typically demands new ovens, rail realignment, and utility work.
• Commercial terms - Take – or – pay clauses guarantee payment obligations even if steel output dips; several legacy contracts in force through 2028-2032 underpin visibility for capital allocation and working capital planning.
• Product specification - SunCoke Energy products meet metallurgical coke quality specs (fixed carbon, CSR, CRI) required by blast furnaces; consistent chemistry reduces mill blending risk and process variability.
• Byproduct and energy integration - Recovery and sale/use of coke oven gas and byproducts lowers customer net energy costs; offering waste – heat energy recovery projects helps customers meet emissions reduction targets and provides an additional value layer.
• Supply chain economics - Rail – dominated logistics and established offtake lanes reduce delivery risk and inventory buffers for mills, lowering working capital needs for customers.

Key quantitative guardrails observed in 2025-2026 that support retention.

• Declared domestic coke capacity: 5.9 million tons; utilization above peer median in 2025 maintained stable cash conversion.
• Contract tenor concentration: significant volumes secured under contracts extending into the late 2020s-2030s, reducing spot – market exposure.
• Revenue stability: take – or – pay provisions convert demand volatility into contractual cash flow, smoothing EBITDA across steel cycles.

Risks that could erode stickiness and prompt customer churn.

• Decarbonization pressure - If blast – furnace owners accelerate shifts to electric – arc furnace (EAF) steelmaking, demand for metallurgical coke could decline structurally.
• Regulatory and permitting - Stricter emissions standards or new permitting hurdles could raise operating costs or force asset retirements.
• Contract expiration clustering - Large volumes rolling off in a narrow window (late 2020s into 2030s) could create renegotiation risk and pricing pressure.

Operational and commercial levers SunCoke Energy can deploy to retain customers.

• Offer long – dated supply and blended pricing to extend contractual terms and reduce customer renegotiation incentives.
• Co – finance decarbonization projects (waste – heat recovery, cogeneration) to deepen economic integration and lower customer emission footprints.
• Enhance product services (just – in – time logistics, tailored coke specs) that raise the effective switching cost beyond capital replacement.
• Develop JV or partnership models to share capex and align incentives with mills transitioning technologies.
