CHARLOTTE, N.C. – April 28, 2020 - Nucor Corporation (NYSE: NUE) today announced consolidated net earnings of $20.3 million, or $0.07 per diluted share, for the first quarter of 2020. Included in the first quarter of 2020 results are losses on assets of $287.8 million, or $0.92 per diluted share, related to our equity method investment located in Italy, Duferdofin Nucor S.r.l. (“Duferdofin Nucor”), as discussed further below.

These quarterly results, excluding the losses on assets charges, are slightly below the quantitative guidance range we released on March 19, 2020. By comparison, Nucor reported consolidated net earnings of $107.8 million, or $0.35 per diluted share, for the fourth quarter of 2019 and consolidated net earnings of $501.8 million, or $1.63 per diluted share, for the first quarter of 2019.

Included in the fourth quarter of 2019 results were non-cash impairment charges of $66.9 million, or $0.17 per diluted share. Included in the first quarter of 2019 results was a benefit of $33.7 million, or $0.08 per diluted share, related to the gain on the sale of an equity method investment in the raw materials segment.

“The global crisis caused by the COVID-19 pandemic has touched the lives of almost everyone in some way, and we would be remiss not to acknowledge the physical, mental and emotional toll so much of the world is experiencing,” said Leon Topalian, Nucor’s President and Chief Executive Officer. “Our thoughts and prayers are with those who are fighting COVID-19 and our condolences are with the victims of this terrible virus and the families and friends who mourn them. We are in awe of those on the front lines – the healthcare workers and first responders - who are tirelessly working to save lives and end this pandemic.

“Over these last several weeks, the spirit of Nucor’s culture has been on full display. Our teammates are not only continuing to serve our customers, but they are also living up to our deeply shared sense of responsibility to the communities in which we operate and live. I want to thank my teammates who have had to change how they work but have not changed the quality and timeliness of what they produce. I also want to thank our customers for their support and continued business in this challenging time and look forward to building even more powerful long-term partnerships. I am confident that we will get through this crisis and emerge stronger from it, by living our culture every day, staying focused and taking care of each other.”

COVID-19 Update
The COVID-19 pandemic continues to have a significant impact on Nucor. Our most important value is the health and safety of our teammates, their families and the communities where we operate. We have formed an internal task force to closely monitor developments related to the pandemic and provide guidance to Nucor facilities. Our facilities around the country are each taking steps to respond to COVID-19 based on the nature of their operations and the actions being taken by their state and local governments. We have restricted travel, upgraded the cleaning practices at our facilities and offices, implemented remote work for teammates wherever possible, and instituted social distancing measures throughout the Company.

Nucor Reports Results for First Quarter of 2020 and Provides Update on COVID-19 Impacts (Continued)

Nucor, we remain committed to protecting our teammates while minimizing disruptions to our customers and supply chain.

Shelter-in-place or stay-at-home orders have been implemented in most of the states where we operate production facilities. In all these jurisdictions, Nucor has been deemed an essential or life-sustaining operation.  Accordingly, we are maintaining production operations sufficient to meet our customers’ ongoing needs.  Our direct reduced iron (“DRI”) facility in Trinidad stopped production on March 30 to comply with the country’s stay-at-home orders. Our DRI facility in Louisiana halted production on April 2 in response to market conditions and out of concern for the health and safety of our teammates in an area of the country that has experienced a particularly aggressive outbreak of COVID-19 cases. The Louisiana DRI facility resumed production operations on April 25 with additional procedures in place to help protect our teammates at that facility.

Outlook
The COVID-19 pandemic’s impact on market conditions has been varied across our different product groups.  While the automotive and energy markets have seen the sharpest decline, nonresidential construction, which is our largest end market, has shown resiliency moving through this pandemic.  Where we have seen impact on nonresidential construction activity, the sentiment is projects would be delayed rather than cancelled. It is also worth noting that there has been a fairly significant supply side response to the pandemic, with a number of our competitors having idled capacity in response to these challenging conditions.  

It is likely that the Company will report a loss in the second quarter of 2020. While the economic outlook is highly uncertain at present, with the duration of the COVID-19 induced downturn difficult to predict, we currently believe that market conditions will bottom in the second quarter and Nucor will return to profitability in the second half of this year.

We believe our financial strength will be a critical factor enabling Nucor to weather this sudden economic downturn, while reliably serving our customers, performing for our investors and remaining an employer of choice for our teammates.  To preserve our flexibility and reliability during this time, the Company has-instituted enterprise-wide efforts to conserve cash and support our teammates, which include, among other things:

At the end of the first quarter of 2020, we had $1.39 billion in cash and short-term investments on hand and our $1.50 billion revolving credit facility remains undrawn and available.  We believe we continue to have access to the capital markets at a reasonable cost of funds. Our credit ratings remain Baa1/A- with stable outlooks at both Moody’s and Standard & Poor’s.

Finally, Nucor has paid and increased its regular, or base dividend, for 47 consecutive years and we expect to continue this practice through this difficult period as well.

Selected Segment Data

Earnings (loss) before income taxes and noncontrolling interests by segment for the first quarter of 2020 and 2019 were as follows (in thousands):

Financial Review

Included in the first quarter of 2020 earnings were losses on assets of $287.8 million, or $0.92 per diluted share, related to our equity method investment in Duferdofin Nucor. Nucor determined that a triggering event occurred in the first quarter of 2020 due to adverse developments in the joint venture’s commercial outlook, which has been further influenced by the COVID-19 pandemic, all of which have negatively impacted the joint venture’s strategic direction. As a part of the losses on assets, Nucor recorded a non-cash impairment charge of $250.0 million, or $0.83 per diluted share, on its equity method investment in Duferdofin Nucor that is included in the steel mills segment earnings. The provision for income taxes is not affected by the impairment charge on the investment, which has caused Nucor's effective tax rate for the first quarter of 2020 to be unusually high. Additionally, the Company fully reserved its €35.0 million ($37.8 million, or $0.09 per diluted share) outstanding note receivable with Duferdofin Nucor. This impact is recorded in Corporate/eliminations.

Nucor’s consolidated net sales increased 10% to $5.62 billion in the first quarter of 2020 compared with $5.13 billion in the fourth quarter of 2019 and decreased 8% compared with $6.10 billion in the first quarter of 2019. Average sales price per ton in the first quarter of 2020 decreased 1% compared with the fourth quarter of 2019 and decreased 13% compared with the first quarter of 2019.

Total steel mill shipments in the first quarter of 2020 increased 12% as compared to the fourth quarter of 2019 and increased 8% as compared to the first quarter of 2019.

Overall operating rates at the Company’s steel mills increased to 89% in the first quarter of 2020 as compared to 83% in the fourth quarter of 2019 and 87% in the first quarter of 2019.

First Quarter of 2020 Analysis

Excluding the impairment charges, the performance of the steel mills segment in the first quarter of 2020 increased compared to the fourth quarter of 2019, due to increased volumes and higher average selling prices at our sheet and bar mills. The profitability of the steel products segment in the first quarter of 2020 increased as compared to the fourth quarter of 2019 (excluding the fourth quarter of 2019 impairment charge), due to increased volumes. The performance of the raw materials segment in the first quarter of 2020 improved as compared to the fourth quarter of 2019, due to an improvement in pricing for raw materials, the absence of the impairment charge related to our proved producing natural gas well assets and improved performance at our DRI facilities.

Commitment to Returning Capital to Stockholders

During the first quarter of 2020, Nucor repurchased approximately 0.8 million shares of its common stock at an average price of $47.88 per share. As of April 4, 2020, Nucor had approximately 301,135,000 shares outstanding and approximately $1.16 billion remaining for repurchases under its authorized share repurchase program.
