    Risks & headwinds

    4
    Flat-rolled market headwinds due to inventory overhangQ3 FY25, expected to diminish by end of Q4 FY25

    Coated flat-rolled steel volume and pricing compressed

    Mitigation: Prices believed to have bottomed and will improve in 2026; positive trade determination will curb imports.

    Higher-than-expected aluminum start-up operating lossesQ3-Q4 FY25

    $57 million in Q3 FY25, estimated $40 million for Q4 FY25

    Mitigation: Accelerating testing for beverage can and automotive products, aiming for monthly EBITDA breakeven in Q4 FY25.

    Planned maintenance outages reducing steel volumeQ4 FY25

    Could reduce volume by as much as 85,000 tons

    Mitigation: Regular maintenance to keep assets performing at tiptop condition.

    Customer caution in placing orders due to trade policiesCurrent

    Not quantified

    Mitigation: Steel prices believed to have stabilized with potential for upward movement in 2026.

    Aluminum Operations EBITDA Breakeven

    Q4 2025
    CurrentOperating losses of $57M in Q3, expected $40M in Q4
    TargetMonthly EBITDA breakeven or better

    Why it matters

    Confirms the ramp-up and profitability of the new aluminum segment, critical for future earnings.

    We currently estimate comparative losses to be in the range of $40 million for the fourth quarter of 2025. Based on current expectations, we continue to believe our aluminum operations will achieve monthly EBITDA breakeven or better in the fourth quarter of this year.

    Q&A highlights

    7

    How do the quality qualifications for aluminum products impact commercial activity and long-term contract negotiations?

    The accelerated qualifications, especially for can sheet and automotive, are incredible and will accelerate the value and product portfolio mix into next year, potentially achieving the target mix earlier in 2027. The company is actively negotiating longer-term contracts for both can sheet and automotive.

    “we are negotiating longer-term contracts, both in the sheet -- the can sheet as well as in the automotive.”

    Detailed Narrative

    01

    Sinton Mill Performance and Product Expansion

    The Sinton flat-rolled steel mill achieved a record quarter for shipments, demonstrating consistent operational execution. Downstream coating and prepaint product quality has matured, and the facility is actively expanding its value-add product portfolio. This includes developing unique high-quality API pipe grades, high-strength grade 100-110, pressure vessel quality, and OEM qualification packages for automotive customers, strengthening its product mix and through-cycle earnings capabilities.

    02

    Aluminum Dynamics Commissioning and Certification Progress

    The aluminum team has made strong progress in commissioning and ramping operations, receiving multiple quality certifications in September and October for industrial, can sheet finished products, and automotive aluminum hot band. Three of the four melt cast houses at Columbus are fully commissioned, producing various series ingots. The hot mill is completing commissioning, and the cold reversing mill is in start-up. Tandem mill #1 will start in November, with Tandem mill #2 and the cash line scheduled for Q1 2026.

    03

    Decarbonization and Sustainability Initiatives

    Steel Dynamics is advancing its decarbonization journey with the biocarbon team shipping its first material in September, which was successfully used at the Columbus flat-rolled steel division. This initiative aims to further reduce the company's carbon footprint. Additionally, all company steel mills achieved Global Steel Climate Council product certifications, providing greater transparency and confidence for customers sourcing lower embodied carbon steel products.

    04

    Favorable Market Dynamics and Trade Policy Impacts

    The company anticipates positive impacts from renewed strategic mercantilist policies, including the recent affirmative final determination on corrosion-resistant steel imports from 10 countries and the announced Section 232 steel tariffs. The inclusion of tariffs on steel content of derivative products, such as fabricated structural steel, is also expected to provide substantial benefit to the domestic industry, which saw 30 million to 35 million tons of steel imported as products in 2024.

    05

    Strategic Capital Allocation and Shareholder Returns

    Steel Dynamics maintains a disciplined and balanced capital allocation strategy, prioritizing high-return strategic growth, shareholder distributions, and preserving investment-grade credit. Since 2017, the company has increased its cash dividend per share by 223% and repurchased $7.4 billion of common stock, representing over 40% of outstanding shares, all while growing and maintaining investment-grade ratings.
