Steel Dynamics Reports Second Quarter 2019 Results

FORT WAYNE, INDIANA, July 22, 2019 / PRNewswire / Steel Dynamics, Inc. (NASDAQ/GS: STLD) today announced second quarter 2019 financial results. The company reported second quarter 2019 net sales of $2.8 billion and net income of $194 million, or $0.87 per diluted share. Comparatively, prior year second quarter net income was $362 million, or $1.53 per diluted share, with net sales of $3.1 billion. Sequential first quarter 2019 net income was $204 million, or $0.91 per diluted share, with net sales of $2.8 billion.

“Our second quarter 2019 consolidated operating income was $285 million and adjusted EBITDA $365 million,” said Mark D. Millett, President and Chief Executive Officer.  “The team delivered a solid second quarter performance in a challenging steel pricing environment.  A weakening scrap price environment coupled with steel inventory destocking led to steel buying hesitancy. Despite these challenges, supported by the addition of United Steel Supply and the continued ramp-up of Heartland, our steel platform shipments improved.  As underlying steel demand remains constructive and scrap prices have steadied, we have recently seen stabilization and improvement in flat roll steel prices, resulting in increased flat roll order activity and improved order backlogs. However, structural, merchant bar, and reinforcing bar steel pricing remain pressured from domestic and import market competition.

“Underlying domestic steel demand remains intact, and we are seeing continued positive activity across most of the steel consuming sectors, including automotive, energy and industrial customers.  Additionally, as evidenced by our strong steel fabrication backlog, strength continues in non-residential construction.”

The company generated strong cash flow from operations of $361 million during the second quarter 2019 and increased liquidity to $2.3 billion. The company paid cash dividends of $54 million and repurchased $93 million of its common stock during the second quarter 2019.

Second Quarter 2019 Comments

Second quarter 2019 operating income for the company’s steel operations was $295 million, or six percent lower than sequential first quarter 2019 results. The decline in earnings resulted from metal spread compression which more than offset the three percent increase in overall steel shipments related to the ramp-up of the Heartland facility and the recent addition of United Steel Supply.  The sequential earnings decline was primarily driven by lower shipments and product pricing within the company’s long product steel operations. The second quarter 2019 average external product selling price for the company’s overall steel operations decreased $23 sequentially to $879 per ton.  The average ferrous scrap cost per ton melted at the company’s steel mills decreased $22 to $316 per ton.

The company’s steel processing locations (Heartland, Techs, United Steel Supply and Vulcan) represented 16 percent of the shipment mix in the second quarter 2019, compared to 13 percent in the sequential quarter and nine percent in the prior year second quarter.  These locations use steel products as their primary raw material, and the associated steel procurement cost represented 18 percent of the steel operations cost of goods sold for the second quarter 2019, 15 percent for the sequential quarter, and nine percent for the prior year second quarter.

Second quarter 2019 operating income from the company’s metals recycling operations decreased to $11 million, compared to $20 million in the sequential first quarter, as a result of both lower nonferrous shipments and ferrous selling values.  Both prime and obsolete scrap indices fell almost $90 per gross ton from March to June 2019.  As scrap flows started to slow based on lower procurement values, scrap pricing appears to have stabilized in July.

Second quarter 2019 operating income from the company’s steel fabrication operations was a strong $31 million, or 49 percent higher than sequential first quarter results. Earnings improved as higher shipments and lower raw material steel input costs, resulted in expanded profit margins. The steel fabrication platform order backlog remains strong, and customers remain optimistic concerning non-residential construction projects.

Year-to-Date June 30, 2019 Comparison

For the six months ended June 30, 2019, net income was $399 million, or $1.78 per diluted share, with net sales of $5.6 billion, as compared to net income of $590 million, or $2.49 per diluted share, with net sales of $5.7 billion for the same period in 2018.  Although net sales remained consistent, first half 2019 operating income decreased 30 percent from record high 2018 results of $825 million, to $577 million.  The decline in earnings was driven by decreased product pricing at the company’s Butler and Columbus Flat Roll divisions as hot roll coil price indices fell approximately $200 per ton, or over 25 percent, since December 2018.

Compared to the first half 2018, the average first half 2019 external selling price for the company’s overall steel operations increased $11 to $890 per ton, based on additional volumes from the company’s Heartland and United Steel Supply locations. The average first half 2019 ferrous scrap cost per ton melted at the company’s steel mills decreased $7 to $327 per ton.

The company generated strong cash flow from operations of $543 million, paid cash dividends of $96 million, and repurchased $177 million of its common stock during the first half of 2019.

Outlook

“Based on domestic steel demand fundamentals, we are constructive concerning second half 2019 North American steel market dynamics,” said Millett. “We believe steel consumption will experience modest growth and will be supported by further steel import reductions and the end of steel inventory destocking.  There have been recent trade actions that we believe could have a positive impact in further reducing unfairly traded steel imports into the United States, including coated flat roll steel, which could have a significant positive impact for Steel Dynamics, as we are the largest non-automotive flat roll steel coater in the U.S.

“In combination with our existing and newly announced expansion initiatives, we believe there are firm drivers for our continued growth.  We are excited about our planned flat roll steel mill, and the anticipated long-term value creation it will bring through geographic and value-added product diversification. We plan for the new steel mill to have product capabilities beyond existing electric-arc-furnace flat roll steel producers today, competing even more effectively with the integrated steel model and foreign competition. We have targeted regional markets that represent over 27 million tons of relevant flat roll steel consumption, which includes the growing Mexican flat roll steel market. This facility should have a meaningful competitive advantage in those regions.

“We continue to strengthen our financial position through strong cash flow generation and the execution of our long-term strategy. We are well-positioned for growth and remain focused on delivering long-term shareholder value through organic and transactional growth opportunities,” concluded Millett.

Note Regarding Non-GAAP Financial Measures

The company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). Management believes that EBITDA and Adjusted EBITDA, non-GAAP financial measures, provide additional meaningful information regarding the company’s performance and financial strength. 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, because not all companies use identical calculations, EBITDA and Adjusted EBITDA included in this release may not be comparable to similarly titled measures of other companies.
