Steel Dynamics Reports First Quarter 2024 Results

FORT WAYNE, INDIANA, April 23, 2024 / PRNewswire /

First Quarter 2024 Performance Highlights:

Steel Dynamics, Inc. (NASDAQ/GS: STLD) today announced first quarter 2024 financial results. The company reported first quarter 2024 net sales of $4.7 billion and net income of $584 million, or $3.67 per diluted share. Comparatively, the company’s sequential fourth quarter 2023 net income was $424 million, or $2.61 per diluted share and prior year first quarter net income was $637 million, or $3.70 per diluted share.

“The teams executed well delivering a solid first quarter performance,” said Mark D. Millett, Chairman and Chief Executive Officer. “Underlying steel demand was steady in the quarter; however, we experienced some steel order volatility early in the quarter as customer inventories remain incredibly low and scrap prices declined month over month in the quarter. Customer orders rebounded strongly in March supporting increased pricing and solid order backlogs, especially within our value-added coated flat rolled steel products portfolio.

“The teams achieved strong first quarter 2024 operating income of $751 million and adjusted EBITDA of $879 million,” continued Millett. “The sequential improvement in earnings was driven by our steel and metals recycling businesses and supported by continued historically strong results from our steel fabrication operations. Across the company, our teams achieved strong performance, while keeping each other safe.”

First Quarter 2024 Comments

First quarter 2024 operating income for the company’s steel operations was $675 million, or 85 percent higher than sequential fourth quarter results, due to solid demand resulting in near-record first quarter steel shipments of 3.3 million tons and higher realized selling values. The automotive, non-residential construction, energy, and industrial sectors lead demand. Flat rolled steel pricing has rebounded from recent lows and steel producer lead times have extended since the end of the first quarter. The first quarter 2024 average external product selling price for the company’s steel operations increased $111 sequentially to $1,201 per ton. The average ferrous scrap cost per ton melted at the company’s steel mills increased $24 sequentially to $417 per ton.

Compared to the sequential fourth quarter, first quarter 2024 operating income from the company’s metals recycling operations increased to $23 million, based on increased demand supporting higher volume and metal spread expansion. Domestic steel production utilization increased from 74 percent in the sequential fourth quarter to 77 percent in the first quarter 2024. The team did an excellent job executing in a falling price environment since December 2023 before prices stabilized in April.

The company’s steel fabrication operations achieved historically strong operating income of $178 million in the first quarter 2024, but below sequential fourth quarter results, based on seasonally lower shipments coupled with a decline in metal spread as realized pricing declined and steel raw material input costs increased in the quarter. The steel fabrication order backlog extends through the third quarter 2024, at pricing levels well above pre-Covid levels. In addition, the continued onshoring of manufacturing, coupled with the robust U.S. infrastructure program and industrial build-outs, supports strong demand for 2024 and beyond.

Based on the company’s differentiated business model and highly variable cost structure, the company generated cash flow from operations of $355 million during the quarter, even after funding the companywide profit-sharing contribution of $265 million. The company also invested $374 million in capital investments, paid cash dividends of $68 million, and repurchased $298 million of its outstanding common stock, representing 1.5 percent of its outstanding shares, while maintaining strong liquidity of $3.1 billion as of March 31, 2024.

Outlook

“We remain confident that market conditions are in place for domestic steel consumption to be strong throughout 2024,” said Millett. “Order entry activity continues to be solid across all of our businesses and steel pricing has firmed. We believe North American steel consumption will increase in 2024, and that demand for lower-carbon emission, U.S. produced steel products coupled with lower imports will support steel pricing. We believe the automotive, non-residential construction, industrial, and energy sectors will remain solid this year. The continued onshoring of manufacturing businesses, combined with the expectation of significant fixed asset investment to be derived from public funding related to the U.S. Infrastructure, Inflation Reduction Act, and Department of Energy programs, will competitively position the domestic steel industry. We believe this will benefit all of our operating platforms, especially our steel and steel fabrication businesses.

“We have successfully started commissioning and operating our four new value-added flat rolled steel coating lines. The teams have produced prime quality galvanized and painted products on the first two lines in record times. We expect to begin benefitting from the additional 1.1 million tons of value-added steel products beginning in the second quarter of this year and fully in 2025.

“We are also quickly progressing on our aluminum flat rolled products mill and are incredibly excited about this meaningful growth opportunity, which is aligned with our existing business and operational expertise,” said Millett. “We plan to begin operating the aluminum flat rolled mill 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 continue to positively differentiate our performance from the rest of the industry. We are competitively positioned and focused to generate long-term sustainable value,” concluded Millett.
