Cleveland-Cliffs (CLF) Q4 2025: $500M Slab Contract Exit Unlocks Margin Expansion for 2026
Cleveland-Cliffs (CLF) enters 2026 with a restructured cost base, a $500 million EBITDA uplift from the slab contract exit, and a robust order book as tariffs and reshoring policies reshape North American steel demand. Management’s tone shifted from defensive to opportunistic, emphasizing capacity leverage, auto contract wins, and a pending POSCO partnership that could redefine U.S. steel supply chains. Investors should watch for throughput gains, cost normalization, and the scale of benefits as policy tailwinds and operational resets converge in the coming quarters.
Summary
- Slab Contract Termination Drives Margin Reset: CLF’s exit from its index-based slab supply deal immediately boosts profitability and strategic flexibility.
- Automotive and Policy Tailwinds Accelerate Recovery: Reshoring and new OEM contracts position CLF to capitalize on a rebound in U.S. vehicle production.
- Strategic Partnership Potential with POSCO: Ongoing negotiations could catalyze further growth and compliance-driven market share gains.
Business Overview
Cleveland-Cliffs (CLF) is a vertically integrated steel producer with operations spanning iron ore mining, steelmaking, and downstream finishing. The company’s primary revenue streams are flat-rolled steel products for the automotive, construction, and appliance sectors, with automotive as its core end market. Major segments include U.S. steel operations, Stelco (Canadian subsidiary), and value-added steel solutions. CLF’s model emphasizes domestic production, cost control, and supply chain integration.
Performance Analysis
CLF closed 2025 under pressure from weak U.S. auto production, import-driven demand gaps, and an onerous slab supply contract that depressed margins. The company responded by shuttering underperforming assets, reducing its workforce by 3,300, and executing a major cost rationalization. Shipments dipped in Q4 due to seasonality, but management expects a return to 4 million tons in Q1 2026 as demand normalizes and asset utilization rises.
The most material shift is the termination of the index-based slab contract with ArcelorMittal, which management quantified as a $500 million EBITDA improvement, with incremental benefit ramping across Q2 and Q3 2026. Price realization is set to rebound by $60 per ton in Q1, and cost per ton is guided to decline for a fourth consecutive year, with additional savings from locked-in coal contracts and a richer sales mix. The order book is described as robust, with automotive contract wins and Canadian market stabilization (post-tariff) providing new upside. Cash flow is expected to recover, with asset sales and lower capex supporting debt paydown.
- Cost Discipline and Asset Rationalization: Three years of unit cost reductions and a leaner operational footprint set the stage for margin expansion as volumes recover.
- Order Book and Price Leverage: Rising spot steel prices and multi-year automotive contracts increase CLF’s sensitivity to price rallies versus peers.
- Stelco Turnaround in Progress: After a challenging 2025, CLF expects its Canadian unit to shift from a drag to a “significant contributor” as Canadian tariffs curb imports.
The combination of policy-driven demand, operational resets, and a favorable pricing environment positions CLF for a materially improved 2026, with execution on throughput and cost normalization as key swing factors.
Executive Commentary
"The expected combination of these market share gains with an increased domestic production of vehicles will be a massive gain for our throughput, efficiency, costs, and ultimately profits."
Lorenzo Goncalves, Chairman, President, and CEO
"Our order book is solid, demand is improving, lead times are going out, prices are rising, costs are still coming down, tariffs are in place, the slab contract is gone, manufacturing is coming back, unemployment is low, rate cuts are here, tax refunds are coming, Stelco's contributing, autos are looking to replace aluminum with steel, POSCO is collaborating, our employees are incentivized, and our operations and commercial teams are working together towards the same goal to maximize profitability in 2026."

Strategic Positioning
1. Slab Contract Exit Unlocks Margin and Strategic Freedom
Terminating the loss-making slab contract with ArcelorMittal immediately removes a major drag, with management guiding to a $500 million EBITDA gain and improved mix. This move also weakens competitors’ access to U.S.-compliant slabs, enhancing CLF’s market leverage.
2. Automotive Reshoring and Contract Wins Build Recurring Revenue
Multi-year fixed-price contracts with all major OEMs secure high-margin business and expand CLF’s share as U.S. vehicle production recovers. The company’s ability to supply incremental volume without new capex is a critical advantage as demand rebounds.
3. POSCO Partnership as a Strategic Accelerator
Ongoing negotiations with POSCO, Korea’s largest steelmaker, could provide CLF with a unique channel to serve U.S. origin-compliant demand, deepen industrial ties, and potentially unlock new capital or technology benefits. Management frames this as the “number one strategic priority.”
4. Canadian Market Stabilization via Tariffs
Stelco, previously a drag due to import dumping and weak pricing, is now positioned for recovery as Canadian tariffs take hold, with management expecting a “night and day” improvement in 2026 contribution.
5. Aluminum Displacement Opportunity
CLF’s steel has been validated as a drop-in replacement for aluminum in automotive applications, with production-scale orders underway. This expands the addressable market and leverages supply chain disruptions in aluminum to CLF’s benefit.
Key Considerations
CLF’s 2025 reset sets the stage for a structurally improved 2026, but execution risk remains as the company transitions from turnaround to growth. The interplay of policy, pricing, and operational leverage will dictate the scale and durability of upside.
Key Considerations:
- Margin Expansion from Slab Contract Exit: The $500 million EBITDA uplift is material, but realization will depend on volume ramp and mix execution.
- Auto Demand Recovery as a Swing Factor: U.S. vehicle production remains below pre-pandemic levels, making the pace of OEM reshoring a critical variable.
- POSCO Partnership Outcome: The scope, structure, and timing of a definitive agreement could reshape CLF’s growth trajectory and capital allocation.
- Cost Normalization and Input Volatility: While unit costs are guided lower, utility and scrap price swings could pressure margins, especially in Q1.
- Asset Sale Proceeds and Balance Sheet Health: Execution on $425 million in asset sales and further deleveraging will influence financial flexibility.
Risks
Execution on throughput, cost discipline, and asset sales is essential as CLF transitions from restructuring to growth. Policy tailwinds could reverse, and any delay in auto production recovery or POSCO partnership finalization would dampen upside. Input cost volatility, especially in utilities and scrap, remains a near-term risk, while global steel oversupply and trade policy uncertainty could pressure long-term margins.
Forward Outlook
For Q1 2026, CLF guided to:
- Shipments returning to 4 million tons, driven by improved demand and lower maintenance downtime
- Average selling price up $60 per ton from Q4, with cost per ton temporarily up $20 before normalizing in Q2
For full-year 2026, management expects:
- Shipments in the 16.5 to 17 million ton range, reflecting higher utilization
- Unit costs down $10 per ton year-over-year, with further improvement from richer mix and slab contract exit
- Capex of $700 million, normalizing after a record-low 2025
Management highlighted:
- Solid order book and improving demand visibility
- Rising spot prices and automotive volume as key profit drivers
Takeaways
CLF’s 2025 actions set up a structurally improved 2026, with margin expansion, operational leverage, and policy tailwinds converging to drive upside. The pace of auto demand recovery and the outcome of the POSCO partnership are key watchpoints for investors.
- Margin Reset: The slab contract termination and cost discipline underpin a step-change in profitability as volumes recover.
- Strategic Optionality: POSCO partnership and asset sales provide levers for further value creation or risk mitigation.
- Execution Watch: Investors should monitor throughput gains, cost normalization, and the realization of order book strength as leading indicators for sustained cash flow recovery.
Conclusion
Cleveland-Cliffs enters 2026 with a stronger foundation, greater margin leverage, and multiple strategic catalysts. The company’s ability to convert policy and contract wins into sustained throughput and cash flow will determine the durability of its recovery and valuation re-rating.
Industry Read-Through
CLF’s experience highlights the impact of policy-driven reshoring, tariff protection, and supply chain localization on North American steel economics. The margin reset from contract renegotiation and the strategic value of U.S.-origin steel underscore the competitive risks for import-dependent peers. The POSCO partnership model may become a template for global players seeking access to protected markets, while aluminum’s supply chain fragility and substitution risk will be closely watched by automakers and materials suppliers. Investors should monitor steelmakers’ ability to flex capacity, manage input volatility, and capture incremental value from regulatory and market shifts in the coming cycle.
