Steel Dynamics Reports Third Quarter 2023 Results

FORT WAYNE, INDIANA, October 18, 2023 / PRNewswire /

Third Quarter 2023 Performance Highlights:

§ Steel shipments of 3.1 million tons

§ Net sales of $4.6 billion, operating income of $734 million, net income of $577 million, and adjusted EBITDA of $876 million

§ Strong cash flow from operations of $1.1 billion and record liquidity of $3.7 billion

§ Share repurchases of $331 million of the company’s common stock, representing 1.8 percent of its outstanding shares

Steel Dynamics, Inc. (NASDAQ/GS: STLD) today announced third quarter 2023 financial results. The company reported third quarter 2023 net sales of $4.6 billion and net income of $577 million, or $3.47 per diluted share.

Comparatively, the company’s sequential second quarter 2023 net income was $812 million, or $4.81 per diluted share, and prior year third quarter net income was $914 million, or $5.03 per diluted share.

“The teams executed well and delivered a solid third quarter performance across our operating platforms,” said Mark D. Millett, Chairman and Chief Executive Officer. “Our third quarter 2023 operating income was $734 million, with adjusted EBITDA of $876 million. The sequential decline in earnings was the result of lower realized flat rolled steel and steel fabrication pricing. The strength of our cash generation was once again demonstrated with cash flow from operations of $1.1 billion. We achieved record liquidity of $3.7 billion, while at the same time continuing to invest in our growth and providing strong shareholder distributions.

“Customer order activity and steel demand were steady during the third quarter, with our steel shipments remaining consistent excluding the lost volume from Sinton’s unplanned July outage of approximately 90,000 tons. The caster shear issues were successfully addressed, and we expect the team to reach about 65 to 70 percent production utilization before the end of the year. Continuing low customer steel inventories combined with steady order activity, stabilized flat rolled steel pricing in mid-September. Recently, there have also been additional price increases related to customer concerns over potential lack of flat rolled steel availability in the fourth quarter, as backlogs have extended.”

Third Quarter 2023 Comments

Third quarter 2023 operating income for the company’s steel operations was $474 million, representing a 33 percent sequential decline based on metal spread compression within the company’s flat rolled steel operations as steel prices decreased more than scrap costs. The third quarter 2023 average external product selling price for the company’s steel operations decreased $66 per ton sequentially to $1,191 per ton. The average ferrous scrap cost per ton melted at the company’s steel mills decreased $39 per ton sequentially to $405 per ton.

Third quarter operating income from the company’s metals recycling operations decreased 54 percent to $19 million, as ferrous scrap shipments declined combined with metal spread compression related to lower realized ferrous and nonferrous scrap pricing. Domestic ferrous scrap demand was impacted due to numerous steel mill maintenance outages during the quarter.

The company’s steel fabrication operations achieved historically strong operating income of $330 million in the third quarter 2023, but below second quarter results, based on lower shipments and metal spread compression as lower realized selling values were combined with steady steel substrate costs. The order backlog extends through the first quarter 2024, with strong forward-pricing. In addition, the company believes that the continued onshoring of manufacturing, coupled with the robust U.S. infrastructure and Inflation Reduction Act programs, combined with industrial construction, supports strong demand in the coming years.

Based on the company’s differentiated business model and highly variable cost structure, the company generated cash flow from operations of $1.1 billion during the third quarter 2023. The company also invested $558 million in capital investments, paid cash dividends of $71 million, and repurchased $331 million of its outstanding common stock, representing 1.8 percent of its outstanding shares, while achieving record liquidity of $3.7 billion as of September 30, 2023.

Year-to-Date September 30, 2023 Comparison

For the nine months ended September 30, 2023, net income was $2.0 billion, or $11.98 per diluted share, with net sales of $14.6 billion, as compared to net income of $3.2 billion, or $17.21 per diluted share, with net sales of $17.4 billion for the same period in 2022.

For the first nine months of 2023, net sales decreased 16 percent to $14.6 billion and operating income declined 39 percent to $2.6 billion, when compared to the same period of 2022. Lower earnings were driven by metal spread contraction within the company’s steel operations, as lower realized product pricing outpaced lower ferrous scrap costs. Operating income from the company’s steel operations for the same period was $1.5 billion, compared to $2.9 billion achieved in the first nine months of 2022. The average nine-month 2023 external selling price for the company's steel operations decreased $316 per ton to $1,175 per ton compared to the same period of 2022, and the average ferrous scrap cost per ton melted at the company’s steel mills decreased $74 per ton to $421 per ton. Operating income for the company’s steel fabrication operations was $1.3 billion for the first nine months of 2023, compared to record results of $1.7 billion achieved for the same period in 2022.

The company generated cash flow from operations of $2.7 billion during the first nine months of 2023. The company also invested $1.1 billion in capital investments, paid cash dividends of $202 million, and repurchased $1.1 billion of its outstanding common stock, representing 5.7 percent of its outstanding shares, while achieving record liquidity.

Outlook

“Based on domestic steel fundamentals, we are constructive regarding North American steel market dynamics,” said Millett. “Customer order entry activity continues to be solid across our steel operations, as demand continues to be steady and customer inventories remain at low historical levels. We believe North American steel consumption will increase in the coming years, and that demand for lower-carbon emission, U.S. produced steel products coupled with lower imports will support steel pricing. 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.

“This environment, in combination with our ongoing expansion initiatives, are firm drivers for our continued growth. The team continues to make great progress on our aluminum flat rolled products mill and related investments. We remain incredibly excited about this meaningful growth opportunity, which is aligned with our existing businesses and operational expertise,” said Millett. “The team has placed orders for all critical equipment, and the Columbus, Mississippi rolling mill site is exceptional. 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 and industrial 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 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 compared to others. We continue to strengthen our financial position through strong cash flow generation and the execution of our long-term strategy,” concluded Millett.

Non-GAAP financial measures should be viewed in addition to and not as an alternative for the company’s reported results prepared in accordance with GAAP. In addition, not all companies use identical calculations for EBITDA or Adjusted EBITDA; therefore, EBITDA and Adjusted EBITDA included in this release may not be comparable to similarly titled measures of other companies.
