Business Context and Reporting Period

This filing covers the quarterly period ended September 30, 2025. Steel Dynamics, Inc. (SDI) operates as a major domestic steel producer and metals recycler with four primary segments: Steel Operations, Metals Recycling, Steel Fabrication, and Aluminum Operations.

The Aluminum Operations segment is nearing completion of construction for its recycled aluminum flat rolled products mill in Columbus, Mississippi.

Key Financial Metrics

Material Changes vs. Prior Period

• Q3 Performance: Net sales increased 11% and operating income rose 28% compared to Q3 2024. This improvement was driven by expanded metal spreads in Steel and Metals Recycling operations, despite a decline in the Steel Fabrication segment.
• 9M Performance: Conversely, for the first nine months of 2025, operating income decreased 32% and net income dropped 31% compared to the same period in 2024. This decline was primarily due to a 7% decrease in metal spreads in the Steel Operations segment during the first half of the year.
• Segment Highlights:
  • Steel Operations: Q3 operating income surged 65% to $496.8 million due to record shipments and improved spreads. However, 9M operating income fell 22%.
  • Metals Recycling: Q3 operating income jumped 414% to $31.5 million, driven by nonferrous metal spreads (particularly copper).
  • Steel Fabrication: Q3 operating income declined 35% to $107.0 million due to a 17% contraction in metal spreads and lower volumes.
  • Aluminum Operations: Reported a loss of $56.5 million in Q3 due to construction and start-up costs.
• Debt Structure: In March 2025, the company issued $1.0 billion in senior unsecured notes ($600M at 5.25% due 2035 and $400M at 5.75% due 2055) to repay maturing debt and fund general corporate purposes.

Guidance, Outlook, and Risks

• Outlook: Management notes hesitancy from customers due to trade uncertainties but cites encouraging demand drivers such as manufacturing onshoring, infrastructure funding, and lower interest rates. The Aluminum Operations segment expects volume to steadily increase as commissioning continues.
• Liquidity: Total liquidity stands at $2.21 billion, including $770 million in cash and $1.19 billion in revolver availability. The company remains in compliance with all debt covenants.
• Capital Allocation: The company increased its quarterly dividend to $0.50 per share (9% increase). It has $1.0 billion remaining under its $1.5 billion share repurchase program authorized in February 2025.
• Risks: Key risks include global steelmaking overcapacity, volatility in scrap metal prices, energy costs, and the cyclical nature of the steel industry. The company also faces potential impacts from the "One Big Beautiful Bill Act" (OBBBA) enacted in July 2025, though management does not expect a material impact on effective tax rates.

Investor Verification Checklist

• Metal Spreads: Verify the sustainability of the Q3 2025 metal spread expansion in Steel and Recycling segments versus the 9M contraction.
• Aluminum Ramp-up: Monitor the timeline and cost trajectory for the Columbus, Mississippi aluminum mill commissioning and its impact on operating losses.
• Debt Servicing: Review the impact of the new 5.25% and 5.75% notes on future interest expense compared to the retired 2.4% notes.
• Fabrication Demand: Assess the order backlog for the Steel Fabrication segment to gauge recovery potential given the 35% Q3 operating income decline.
• Scrap Pricing: Track domestic ferrous scrap pricing trends, as this represents 55-65% of steel manufacturing costs.
