Steel Dynamics Reports Fourth Quarter 

and Annual 2025 Results

FORT WAYNE, INDIANA, January 26, 2026 / PRNewswire /

Annual 2025 Performance Highlights:

Steel Dynamics, Inc. (NASDAQ/GS: STLD) today announced fourth quarter and annual 2025 financial results. The company reported fourth quarter 2025 net sales of $4.4 billion and net income of $266 million, or $1.82 per diluted share. Comparatively, the company’s sequential third quarter 2025 net income was $404 million, or $2.74 per diluted share, and prior year fourth quarter net income was $207 million, or $1.36 per diluted share.

“The teams delivered solid operational and financial performance across our operating platforms in 2025, generating annual net sales of $18.2 billion, operating income of $1.5 billion, and adjusted EBITDA of $2.2 billion,” said Mark D. Millett, Chairman and Chief Executive Officer. “This performance demonstrates the strength and consistency of our cash generation, as we generated $1.4 billion in cash flow from operations during the year, after investing $450 million in growth working capital associated with our new aluminum products platform. Our three-year after-tax return-on-invested-capital of 14 percent is a testament to our ongoing high-return capital allocation strategy. We are growing, returning capital to shareholders, and maintaining strong returns as compared to best-in-class domestic manufacturers.

“The aluminum and biocarbon teams continue to make strong progress,” continued Millett. “We have successfully produced finished aluminum flat-rolled products for the industrial and beverage can markets, as well as hot band for the automotive sector. Although there is still work ahead, the team has strong momentum and achieved positive EBITDA in December, positioning us well as we continue commissioning and ramping operations. Additionally, the SDI Biocarbon Solutions team is continuing to refine operations and increase production, providing a significantly lower-carbon supply chain opportunity for our steel and steel fabrication customers.

“We also achieved record annual steel shipments as imports declined from the elevated levels experienced during the first half of the year and as Sinton’s year-over-year operating performance improved,” said Millett. “We are seeing an improved flat rolled steel market environment, supported by domestic trade actions, manufacturing onshoring, infrastructure program funding, lower interest rates, and the increasing regionalization of supply chains in the U.S. Long product steel demand remains very strong, especially for structural steel and railroad rail. Looking ahead, we expect to benefit from strong demand across our platforms.”

Fourth Quarter 2025 Comments

Fourth quarter 2025 operating income for the company’s steel operations was $322 million, or 35 percent lower than sequential third quarter results, due to lower average realized selling values and lower volumes related to both seasonal demand and planned maintenance outages at the company’s flat rolled steel mills. In addition to lower seasonal activity, some of the planned maintenance outages were longer in duration than originally anticipated and decreased volume in the fourth quarter by an estimated 140,000 to 150,000 tons of flat rolled steel production. The fourth quarter 2025 average external product selling price for the company’s steel operations decreased $12 sequentially to $1,107 per ton. The average ferrous scrap cost per ton melted at the company’s steel mills decreased $7 per ton sequentially to $374 per ton. Average realized flat rolled steel pricing declined in the quarter based on lagging priced contracts, while long product steel prices increased as demand for structural and rail products was strong. The energy, non-residential construction, automotive, and industrial sectors led steel demand in the quarter.

Fourth quarter 2025 operating income from the company’s metals recycling operations was $19 million, or $13 million lower than sequential earnings, based on lower selling values and decreased shipments across the platform.

The company’s steel fabrication operations generated operating income of $91 million in the fourth quarter 2025, lower than sequential third quarter results of $107 million, based on seasonally lower shipments more than offsetting modest metal spread expansion, as average selling values improved slightly and steel raw material costs declined. Order activity remained steady in the quarter, with the order backlog maintaining solid levels extending through the first half 2026, supported by stable pricing. Demand was largely driven by the commercial, data center, manufacturing, warehouse, and healthcare sectors. Looking ahead, the pace of domestic manufacturing investment, increased domestic onshoring activity, and momentum from the U.S. infrastructure program are expected to further support demand.

On November 21, 2025, the company issued $800 million in unsecured notes, comprised of $650 million of 4.000% notes due 2028 and $150 million of 5.250% notes due 2035. The net proceeds from the notes were used to redeem the company’s $400 million 5.000% Notes due 2026 and for other general corporate purposes.

Based on the company’s differentiated business model and highly variable cost structure, the company generated cash flow from operations of $273 million during the quarter. The company also invested $188 million in capital investments, paid cash dividends of $73 million, and repurchased $240 million of its outstanding common stock, representing one percent of its outstanding shares.

Annual 2025 Comparison

Annual 2025 net income was $1.2 billion, or $7.99 per diluted share, with net sales of $18.2 billion, as compared to net income of $1.5 billion, or $9.84 per diluted share, with net sales of $17.5 billion for the same period in 2024.

Annual 2025, net sales increased 3.6 percent to $18.2 billion, and operating income declined 24 percent to $1.5 billion, when compared to the same period of 2024. Decreased earnings were the result of lower realized pricing in the company’s steel and steel fabrication operations. Annual 2025 operating income from the company’s steel operations and steel fabrication operations declined $155 million and $260 million, respectively, when compared to the prior year. The average 2025 external selling price for the company’s steel operations decreased $15 to $1,089 per ton compared to 2024, and the average ferrous scrap cost per ton melted at the company’s steel mills increased $1 to $387 per ton.

Based on the company’s differentiated circular business model and highly-variable cost structure, the company generated strong cash flow from operations of $1.4 billion during 2025. The company also invested $948 million in organic growth investments, paid cash dividends of $291 million, and repurchased $901 million of its outstanding common stock, representing over four percent of its outstanding shares, all while maintaining strong liquidity of $2.2 billion as of December 31, 2025.

Outlook

“We anticipate that improving market conditions, including increased trade stability and a more favorable interest rate environment, will support solid domestic demand for steel and aluminum products,” continued Millett. “Steel pricing has improved, and customer optimism remains solid across our businesses, as demand continues to be steady. Additionally, discussions with our customers further underscore the growing importance of lower-carbon, domestically produced steel and aluminum products, positioning our businesses for a sustainable long-term competitive advantage. As unfair trade practices diminish, policy clarity improves, and U.S. manufacturing continues to expand, we believe a favorable market environment will follow.

“The aluminum team is continuing with the successful commissioning and startup of the company’s Columbus, Mississippi aluminum flat rolled products mill and San Luis Potosi satellite recycled aluminum slab center. The cast houses and hot strip mill are operating extremely well, and commissioning is ongoing in other areas of the facility. The teams shipped products for the industrial and beverage can sectors, receiving product qualifications from several customers. They also produced and shipped aluminum hot band for use in automotive applications. We continue commissioning the cold mill and other downstream operations, including the CASH line. It is an extremely exciting time for all of us. There is still much to be done, yet much has also been accomplished.

"We have deliberately aligned our growth strategy with our customers’ developing needs, prioritizing product excellence, supply-chain efficiency, and sustainability. Building on our strong positions in steel, we are expanding into high recycled-content aluminum to serve adjacent markets where customer demand is accelerating. This opportunity spans the counter-cyclical beverage can and packaging segment and extends to automotive, industrial, and construction applications. Backed by a performance-based culture and a proven ability to develop and operate cost-efficient, high-margin mills, we are well positioned to deliver attractive long-term value through this expansion.

“Our unwavering commitment to the health and safety of our teams, families, and communities underpins our ability to meet both current and future customer needs. Our differentiated culture and business model continue to drive performance, while strong cash flow generation and disciplined execution of our long-term strategy are strengthening our financial position,” concluded Millett.
