Valmont Reports First Quarter 2018 Results

Omaha, NE - Valmont Industries, Inc. (NYSE: VMI), a leading global provider of engineered products and services for infrastructure development and irrigation equipment and services for agriculture, today reported first quarter 2018 results.

First Quarter Highlights:

·                  Revenues increased 9.6% to $698.7 million, reflecting higher pricing to recover inflation, volume increases in all segments except Utility, and favorable foreign currency translation effects

·                  Deployed capital for share repurchases, two acquisitions in the Irrigation segment, and investments in existing factories in the U.S., Poland, and the United Arab Emirates

·                  The sale of Donhad Pty. Ltd, the mining consumables business in Australia, was approved by Australian regulatory authorities, with expected closing by April 30

·                  Incurred pre-tax restructuring expense of $4.4 million during the quarter, predominately cash, equivalent to $0.15 per share, after-tax

·                  Increasing 2018 annual guidance for GAAP diluted EPS to a range of approximately $7.70-$7.80, and adjusted diluted EPS to a range of approximately $8.00-$8.10, to reflect the above-mentioned acquisitions, share repurchase effects, and approximately $10.0 million of restructuring charges

“Increased revenue across all reportable segments led to a good start to the year for Valmont, including double-digit growth in the Coatings and Irrigation segments,” said Stephen G. Kaniewski, President and Chief Executive Officer. “One of our key strategies is pursuing international growth, which resulted in revenue gains across several regions.”

Added Mr. Kaniewski, “In the Irrigation, Utility and Coatings segments, we were successful in recovering most raw material cost increases. Longer backlogs with fixed-price contracts in the Engineered Support Structures segment, hampered our ability to fully recover raw material cost increases during the quarter. The slight decrease in overall operating income for the Company is mostly attributable to restructuring expenses, and the lack of profitability in the grinding media business.”

First Quarter Segment Review

Infrastructure

Engineered Support Structures Segment (32% of Sales)

Poles, towers and components for the global lighting, traffic and wireless communication markets, engineered access systems, integrated structure solutions for smart cities, and highway safety products

Sales of $225.0 million were 9.8% higher than last year, led by increased highway safety product sales in Australia, improved structures sales across North America and Europe, and favorable currency translation effects.

Lighting sales improved in North America, driven by increased volumes in both transportation and commercial markets. Ongoing infrastructure investments by the Australian and Indian governments to promote safer roads resulted in increased highway safety product sales in those regions. In Europe, lighting sales also grew, aided by economic recovery across the region that began mid-2017.

Sales of North American wireless communication products and components were higher compared to last year, due to widespread demand from carriers and tower companies. In the Asia Pacific region, sales were lower as a result of reduced demand in the China market. Access Systems sales were also lower, due to project sales that did not repeat.

Operating income was $6.9 million or 3.1% of sales ($10.6 million, or 4.7% adjusted(1)) compared to $9.5 million, or 4.6% of sales in 2017. Price increases implemented during the quarter did not fully recover cost increases, and this is expected to carry over into to the second quarter. It is anticipated, however, that these pricing actions will lead to improved profitability in the second half of the year.

Utility Support Structures Segment (30% of Sales)

Steel and concrete structures for global utility transmission, distribution and generation applications, wind and offshore structures, and inspection services

Sales of $209.9 million increased 4.8% over last year, supported by utility investments in the North American grid to improve reliability and connectivity, and increased demand for renewable projects. Pricing to reflect higher steel costs led to the sales growth.  International utility sales benefited from shipments of highly-engineered PyraMAXTM structures.

Operating income decreased slightly to $23.4 million or 11.1% of sales ($24.1 million or 11.5% adjusted(1)), compared to $24.2 million or 12.1% in 2017, due to a less favorable product mix, partially offset by improved operational leverage.

Coatings Segment (12% of Sales)

Global galvanizing, painting and anodizing services to preserve and protect metal products

Sales of $84.9 million were 15.5% higher than last year, reflecting improved external market demand from economic growth across all regions. Sales to other Valmont segments were also higher.

Operating income was $11.9 million, or 14.0% of sales, compared to $9.4 million, or 12.8% of sales in 2017. Higher volumes, price recovery and improved operating leverage contributed to favorable results.

Agriculture

Irrigation Segment (27% of Sales)

Agricultural irrigation equipment, parts, services and tubular products, water management solutions, and technology for precision agriculture

Global revenue of $188.0 million was 12.4% above last year, led by robust international sales and significant project business. North American sales approximated first quarter 2017. Continued low net farm income levels and a late start to the planting season muted demand; however, the continued adoption of precision irrigation technology solutions supported sales.

Operating income was higher at $33.9 million, or 18.0% of sales, compared to $30.3 million, or 18.1% of sales in 2017. Segment profitability increased in line with sales growth.

During the quarter, the Company acquired a majority stake in Torrent Engineering and Equipment based in Warsaw, Indiana. Torrent is a global designer and integrator of water systems and pump stations for agricultural and industrial applications, with annual sales of approximately $9.0 million. The Company also acquired the remaining outstanding shares of its irrigation subsidiary in Uberaba, Brazil, increasing its overall stake from 90% to 100%.

Other (3% of Sales)

Manufacture of forged steel grinding media for the mining industry

Sales in grinding media were $18.4 million compared to $19.6 million in 2017, a decline of 6.1%. First quarter operating loss was $0.6 million compared to operating profit of $2.1 million in 2017. The sale of the grinding media business is expected to close by April 30.

2018 Restructuring Plan

As announced in February, the Company initiated a restructuring plan at the beginning of the year. During the quarter, restructuring actions taken included the consolidation and closure of certain facilities, and realignment of back-office and management functions. As the Company analyzes its optimal footprint and cost structure, further actions may be considered.

2018 Outlook:

“Signs of stronger economic growth in many regions should contribute to favorable sales comparisons this year across most of our businesses,” Mr. Kaniewski said. “While continued weakness in the U.S. farm economy, and the uncertainty surrounding tariffs could impact customer demand, our diversified, global sales and manufacturing presence should help mitigate these impacts. Our teams are executing on the longer-term strategies communicated at our Investor Day, and we continue to pursue disciplined acquisitions in our core businesses. We have increased our EPS guidance to reflect our capital allocation activities during the quarter, and are on target to meet our annual and long-term financial goals.”
