Steel Dynamics, Inc. (NASDAQ/GS: STLD) today announced fourth quarter and annual 2016 financial results.  The company reported fourth quarter net sales of $1.9 billion and net income of $20 million, or $0.08 per diluted share, which includes non-cash goodwill and asset impairment charges of $0.31 per diluted share and debt refinancing and repayment charges of $0.04 per diluted share. Excluding these items, the company’s adjusted fourth quarter 2016 net income was $106 million, or $0.43 per diluted share.

As indicated in the company’s December 16, 2016 guidance press release, based on recent events related to the company’s 82%-owned and idled Mining Resources joint venture, the company assessed the carrying value of its Minnesota iron mining operations during the fourth quarter 2016.  Upon completion of the assessment, it was determined that the estimated fair value did not support the carrying value in place.  Therefore, the company recorded a pretax, non-cash asset impairment charge of $127 million during the fourth quarter 2016, and based on the company’s joint venture ownership percentages, reduced consolidated pretax income by $114 million.  The planned sale of certain metals recycling assets also resulted in a pretax, non-cash goodwill impairment charge of $5.5 million during the fourth quarter 2016.

The fourth quarter 2016 also included additional compensation costs of approximately $7.5 million, or $0.02 per diluted share, associated with a one-time, special cash performance bonus paid to all non-executive, eligible employees in recognition of their tremendous performance during the year.

Comparatively, prior year fourth quarter net sales were $1.6 billion, with adjusted net income of $22 million, or $0.09 per diluted share, which excluded the impact of non-cash goodwill and asset impairment charges related to the company’s metals recycling operations of $1.13 per diluted share.  Sequential third quarter 2016 net sales were $2.1 billion, with adjusted net income of $160 million, or $0.65 per diluted share, which excluded the impact of a litigation settlement charge of approximately $5 million, or $0.01 per diluted share.

“We continue to perform at the top of our industry, both operationally and financially,” said Mark D. Millett, President and Chief Executive Officer. “We achieved record steel and fabrication shipments, and excluding the previously mentioned impairment charges, we earned record adjusted operating income of $861 million and near record adjusted EBITDA of $1.2 billion.  The industry benefited this year from reduced flat roll steel imports, coupled with steady demand.  Our steel operations profitability declined significantly in the fourth quarter, as customers’ hesitancy to place orders earlier in the quarter resulted in both lower shipments and product pricing.  However, supported by steady demand and a more favorable supply environment, rising world steel prices, and increasing raw material costs, both flat roll steel selling values and customer order activity increased meaningfully in November and December, and remain strong with an expectation for continued strength into 2017.”

“Operating income from our metals recycling platform (excluding the impairment charge) remained steady in the fourth quarter 2016, despite lower seasonal domestic steel mill utilization, which resulted in weakened demand,” continued Millett. “The benefit from the team’s continued focus on cost reduction and better alignment of metals recycling assets helped offset lower shipments and slightly lower metal spread.  Earnings from our fabrication operations also remained steady in the quarter, as the benefit from metal spread expansion more than offset lower seasonal shipments.  Our fabrication platform continues to experience steady demand from the non-residential construction sector.  Based on continued strong generation of cash flow from operations of $853 million for 2016, we maintained near-record liquidity of over $2.0 billion, while simultaneously investing in our company and reducing debt during the year. We have a firm foundation for continued growth.”

Additional Fourth Quarter 2016 Comments

Fourth quarter 2016 operating income for the company’s steel operations decreased 30 percent to $218 million sequentially, based on a three percent decline in shipments and metal spread compression.  The company’s average steel product price decreased more than consumed raw material scrap costs, resulting in steel metal spread compression.  The fourth quarter 2016 average product selling price for the company’s steel operations decreased $60 to $680 per ton.  The average ferrous scrap cost per ton melted only decreased $31 to $220 per ton.

Fourth quarter 2016 operating income attributable to the company’s flat roll products decreased 33 percent when compared to the sequential third quarter, driven by lower shipments and a meaningful decline in metal spread, based on lower selling values that outpaced decreasing scrap costs. Operating income from long products decreased 16 percent as a result of overall lower shipments.  Aside from the construction sector, long product steel demand is generally challenged, and selling values remain under pressure from excess domestic production capability.  The company’s steel production utilization rate was 81 percent in the fourth quarter 2016, compared to 85 percent in the sequential third quarter and compared to the domestic industry utilization rate of less than 70 percent.

Excluding non-cash goodwill impairment charges of $5.5 million, fourth quarter 2016 operating income from the company’s metals recycling operations remained steady at $10 million, compared to the sequential third quarter.  Despite lower average quarterly ferrous pricing, metal spread only decreased slightly.

The company’s fabrication operations recorded fourth quarter 2016 operating income of $18 million, which equaled sequential third quarter results, a strong performance given the impact of seasonality.  Higher average steel input costs were more than offset by improved product selling values, resulting in sequential metal spread expansion, which offset seasonally lower shipments.

During the fourth quarter 2016, the company successfully refinanced $400 million of its highest cost senior notes, reducing its ongoing interest burden and extending its debt maturity profile.  On December 14, 2016, the company also utilized available cash to repay $228 million of its senior secured term debt facility.  These actions reduced fourth quarter 2016 pretax income by approximately $17 million, due to the required call premium and other associated finance expenses. In combination, these transactions are expected to reduce the company’s annual interest expense by approximately $10 million in 2017, and further strengthen and add flexibility to the company’s long term capital structure and credit profile, supporting continued growth.

Annual 2016 Comparison

Annual 2016 net income was $382 million, or $1.56 per diluted share.  Excluding charges related to litigation settlement, non-cash goodwill and asset impairment, and debt capital structure activities, the company reported adjusted net income of $472 million, or $1.92 per diluted share.  Comparatively, annual 2015 net loss was $130 million, or $0.54 per diluted share, which included non-cash asset impairment and other charges related to the company’s metals recycling and ferrous production operations and refinancing costs.  Excluding these charges, annual 2015 adjusted net income was $178 million, or $0.74 per diluted share.

Annual 2016 net sales were $7.8 billion, compared to $7.6 billion in 2015.  The company’s steel and fabrication operating platforms each achieved annual shipping records in 2016 and despite lower average selling values, drove the increase in 2016 revenues.  Annual 2016 adjusted operating income increased $463 million, more than double 2015 results, based on record annual operating income from the company’s steel operations related to both increased shipments and metal spread expansion.  The average 2016 selling price for the company’s steel operations decreased $17 to $658 per ton.  The average 2016 ferrous scrap cost per ton melted decreased $35 to $220 per ton.  The company’s metals recycling platform also experienced a significant improvement in annual profitability based on metal spread expansion, achieving 2016 adjusted operating income of $40 million, compared to a loss of $4 million in 2015 (excluding non-cash goodwill and asset impairment charges).

Outlook

“The company believes that current and anticipated macroeconomic and market conditions are in place to benefit the domestic steel industry in the coming year,” said Millett.  “Although domestic automotive production may be coming off record levels, we believe 2017 North American automotive steel consumption will be steady, and that there will be additional growth in the construction sector, especially for larger, public sector infrastructure projects.  We could also see some improved activity within the energy sector in 2017.

“We continue to see progress at our Columbus Flat Roll Division.  The successful market and product diversification that we achieved at Columbus during 2015 was one of our key differentiators for improved annual profitability in 2016, and will continue to benefit the coming years as we have accessed numerous new customers and end markets. The team also successfully added the capability to produce value-added Galvalume® flat roll products during the third quarter 2016, and successfully installed the $100 million paint line in the fourth quarter of 2016, adding 250,000 tons of value-added painting capability. The team shipped prime Galvalume® product in the second half of 2016 and just shipped its first prime painted product a few weeks ago.

“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 shareholder value through organic and strategic growth opportunities,” concluded Millett.
