Steel Dynamics Reports First Quarter 2025 Results

FORT WAYNE, INDIANA, April 22, 2025 / PRNewswire /

First Quarter 2025 Performance Highlights:

Steel Dynamics, Inc. (NASDAQ/GS: STLD) today announced first quarter 2025 financial results. The company reported first quarter 2025 net sales of $4.4 billion and net income of $217 million, or $1.44 per diluted share. Comparatively, the company’s sequential fourth quarter 2024 net income was $207 million, or $1.36 per diluted share and prior year first quarter net income was $584 million, or $3.67 per diluted share.

“The teams executed well, achieving a solid first quarter 2025 performance, increasing sequential operating income 16 percent and adjusted EBITDA 21 percent,” said Mark D. Millett, Chairman and Chief Executive Officer. “The improvement in earnings was driven by record steel shipments and supported by solid results from our metals recycling and steel fabrication operations. Our three-year after-tax return-on-invested capital of 20 percent is a testament to our ongoing high-return capital allocation execution. Across the company, our teams had a solid performance, while keeping each other safe.

“Underlying steel demand improved in the first quarter as customer orders rebounded and backlogs increased throughout the quarter at our steel and steel fabrication operations. Steel prices improved throughout the quarter from the lows seen in the second half of 2024 as trade actions have seen imports decline from recent highs. We should see the benefit from these higher steel prices in the coming months, as lagging flat rolled steel contracts roll. In combination with our ongoing value-added flat rolled steel and aluminum expansion initiatives, there are firm drivers in place for our continued growth.”

First Quarter 2025 Comments

First quarter 2025 operating income for the company’s steel operations was $230 million, or 39 percent higher than sequential fourth quarter results, due to record shipments more than offsetting metal spread compression, as lagging contractual flat rolled steel pricing in the quarter did not reflect recent price improvements, which will be realized in the coming months. The first quarter 2025 average external product selling price for the company’s steel operations decreased $13 sequentially to $998 per ton. The average ferrous scrap cost per ton melted at the company’s steel mills increased $16 sequentially to $386 per ton. The energy, non-residential construction, automotive, and industrial sectors led steel demand in the quarter. Flat rolled steel pricing has rebounded from recent lows and steel producer lead times have extended. The company’s Sinton Texas Flat Roll Division operated at an 86 percent rate of capacity for the full quarter and often times at production levels in excess of 90 percent. Value-added product quality and cost efficiency initiatives have been successful and are ongoing, providing a clear path to significantly higher escalating profitability in the coming quarters. Sinton was EBITDA positive for the first quarter 2025.

Compared to the sequential fourth quarter, first quarter 2025 operating income from the company’s metals recycling operations increased to $26 million, based on stronger realized ferrous scrap pricing and modestly higher shipments across the platform.

The company’s steel fabrication operations achieved operating income of $117 million in the first quarter 2025, below sequential results due to seasonally lower shipments combined with metal spread compression related to lower realized pricing. The pace of order activity increased during the first quarter, improving the order backlog which extends into the fourth quarter 2025, with attractive pricing levels. Improved demand was supported largely by the commercial, data center, manufacturing, warehouse, and healthcare sectors. Further, the accelerated announcements related to meaningful domestic investments in manufacturing and increased onshoring, coupled with the U.S. infrastructure program, are expected to positively impact demand for not only steel joist and deck products, but also for flat rolled and long product steel.

On March 12, 2025, the company issued $1.0 billion in unsecured notes, comprised of $600 million of 5.250% notes due 2035 and $400 million of 5.750% notes due 2055. The net proceeds from the notes will be used for general corporate purposes, which may include repayment of the company’s $400 million 2.400% senior notes due June 2025.

Based on the company’s differentiated business model and highly variable cost structure, the company generated cash flow from operations of $153 million during the quarter, even after funding the companywide retirement profit-sharing distribution of $165 million. The company also invested $306 million in capital investments, paid cash dividends of $70 million, and repurchased $250 million of its outstanding common stock, representing 1.3 percent of its outstanding shares, while maintaining strong liquidity of $2.6 billion as of March 31, 2025.

Outlook

“We remain constructive that market conditions are in place for domestic steel consumption to be solid through 2025 and into the following years,” said Millett. “Order entry activity improved across our businesses and steel pricing firmed in the first quarter 2025. However, we have seen some uncertainty from certain customers related to recent trade actions. Overall, we believe demand for lower-carbon emission, U.S. produced steel products coupled with lower imports will support steel pricing and demand. The continued onshoring of manufacturing businesses, combined with the expectation of fixed asset investment to be derived from public and private funding should competitively position the domestic steel industry. We also expect the recent International Trade Commission’s preliminary determinations related to coated flat rolled steel to reduce the amount of unfairly traded imports of these products into the United States, which could have a significant positive impact for us, as we are the largest non-automotive flat rolled steel coater in the United States. We believe these broader dynamics will benefit all of our operating platforms.

“Our four new value-added flat rolled steel coating lines continue to increase utilization and we expect to realize full run rate earnings potential in the second half 2025. Value-added product investments such as these enhance our differentiated supply-chain capabilities, while also increasing our higher-margin product offerings, which already represent over 65 percent of our steel revenues.

“The aluminum team is continuing with successful commissioning of the company’s Columbus, Mississippi aluminum flat rolled products mill, along with the San Luis Potosi, Mexico satellite recycled slab center. The Mississippi team successfully cast its first aluminum ingot in January 2025 and the Mexico team in March 2025. Construction is near completion on the hot and cold mills. The finishing equipment installation for the automotive treatment and can sheet coating lines are also on schedule. The company continues to expect to ship commercial aluminum flat rolled coils mid-2025.

“We have intentionally grown with our customers’ needs, providing efficient sustainable supply-chain solutions for the highest quality products. Thus far, this has primarily been achieved within the steel industry — however, a significant number of our flat rolled steel customers are also consumers and processors of aluminum flat rolled products. We are pleased to further diversify our end markets with plans to supply aluminum flat rolled products with high recycled content to the countercyclical sustainable beverage can and packaging industry, in addition to the automotive, industrial, and construction sectors. We believe our unique performance-based operating culture, coupled with our considerable experience in successfully constructing and operating cost-effective, highly profitable flat rolled steel mills, positions us exceptionally well to execute this strategic opportunity and to deliver strong long-term value creation. Our customers and our people are also incredibly excited for this growth opportunity.

“Our commitment is to the health and safety of our teams, families, and communities, while meeting the current and future needs of our customers. Our culture and business model continues to positively differentiate our performance from the rest of the industry. We continue to focus on delivering superior value to our team members, customers, and shareholders,” concluded Millett.
