Steel Dynamics, Inc. (NASDAQ: STLD) provided robust third quarter 2026 earnings guidance on September 17, 2026, projecting diluted earnings per share between $5.34 and $5.38 according to an SEC Form 8-K Exhibit 99.1 press release filed on September 18. Using the $5.36 midpoint, the range is 45.3% above second-quarter EPS and 95.6% above prior-year third-quarter EPS. The company attributed higher expected steel-operations profitability to metal-margin expansion and record shipments. Separately, it said fabrication demand remains healthy across data centers, warehouses, manufacturing, healthcare and commercial construction.
Key Takeaways
- Substantial Earnings Acceleration: Projected Q3 diluted EPS of $5.34 to $5.38 outpaces sequential Q2 earnings of $3.69 per share and prior-year Q3 earnings of $2.74 per share.
- Fabrication Backlog Nearly 50% Higher: The company said its fabrication backlog was nearly 50% above the prior-year third-quarter level and extended through the first quarter of 2027. It listed data centers, warehouses, manufacturing, healthcare and commercial construction among healthy demand markets.
- Capital Deployment & Expansion: Steel Dynamics said it had repurchased $261 million of common stock so far in the quarter and that all three cold mills at its Columbus, Mississippi aluminum facility were operational.
Earnings Outlook and Sequential Margin Expansion
In its formal regulatory disclosure via SEC Form 8-K, Fort Wayne, Indiana-based Steel Dynamics outlined a significant sequential step-up in profitability across its primary operating platforms. Management said expected steel-operations profitability would be significantly higher than in the second quarter, with metal-margin expansion and record shipments. It expected higher average realized selling values together with lower scrap costs.
The company said customer inventories remained low and order activity remained strong, with demand led by non-residential construction, energy, automotive and industrial markets.

Data Center Infrastructure and Steel Fabrication Demand
The most consequential structural signal in the company’s guidance update centers on downstream steel fabrication. Steel Dynamics stated that its steel fabrication order backlog is nearly 50 percent higher than prior-year third quarter levels and extends through the first quarter of 2027.
The release did not break the backlog into end-market percentages. It identified commercial construction, data center and warehouse development, manufacturing and healthcare as healthy demand markets. Readers tracking AI infrastructure should therefore treat data centers as one disclosed contributor, not the sole cause of the backlog increase.
The company expected stronger fabrication shipments to more than offset metal-spread compression caused by higher steel input costs. Its outlook for further 2027 volume growth cited domestic manufacturing investment, U.S. infrastructure spending and stimulus programs, and ongoing onshoring activity. Those statements are forward-looking and are not guarantees of future orders or earnings.
Recycling Operations and Aluminum Startup Milestones
Performance across the broader portfolio demonstrated differentiated cyclical dynamics. In metals recycling, third-quarter earnings are anticipated to soften sequentially due to compressed metal spreads and modestly lower shipment tonnages, reflecting tight ferrous scrap availability.
Conversely, the emerging aluminum platform is nearing commercial scale. Steel Dynamics reported meaningful sequential earnings improvement in aluminum, driven by higher shipment volumes. At its aluminum flat rolled products mill in Columbus, Mississippi, all three cold mills are now operational. The company confirmed that its initial Continuous Annealing and Solution Heat (CASH) line is running and scheduled to ship commercial material during the fourth quarter of 2026, with a second line slated for customer qualification before year-end.
Capital Allocation and Share Repurchases
Steel Dynamics reported that it had repurchased $261 million, or just under one percent, of its common stock so far during the third quarter. The release did not state a motive for the repurchases or provide a complete cash-flow or balance-sheet update, so the buyback alone should not be treated as proof of management’s valuation view or future free cash flow.

What to Watch Next
Steel Dynamics said it planned to release third-quarter 2026 earnings after market close on Monday, October 19, 2026, followed by an executive conference call on Tuesday, October 20, at 11:00 a.m. Eastern Daylight Time. Key metrics to monitor include realized steel pricing per ton, updated commercial shipment timelines from the Columbus aluminum mill, and order intake commentary regarding 2027 non-residential construction contracts.

Correction, September 21, 2026: The headline and body were revised to separate the company-wide steel-operations outlook from its multi-market fabrication backlog, change “50%” to “nearly 50%,” remove an invalid cross-period percentage and unsupported buyback inference, and identify the October release as earnings rather than audited results.
