Total Year Highlights:

·                  Full-year revenues declined 4% mostly due to the revenue impact of lower cost steel in the Utility Support Structures Segment and foreign exchange translation

·                  GAAP operating income increased $111.8 million and adjusted operating income(1) increased 8%, or $18.4 million

·                  GAAP diluted EPS were $7.63, compared to $1.71 last year and adjusted diluted EPS(1) were $6.42, compared to last year’s $5.63, up 14%

·                  The Company completed its announced restructuring plans and incurred $12.4 million of pre-tax restructuring expense in 2016; total savings realized from restructuring actions approximate $22 million

“We are pleased with our revenue growth in the fourth quarter,” said Mogens C. Bay, Valmont’s Chairman and Chief Executive Officer. “Utility Support Structures Segment sales benefited from a stronger North American market. The Engineered Support Structures and Energy and Mining Segments had double-digit revenue gains. Coatings Segment sales equaled last year, as internal utility volumes offset lower external demand. Irrigation Segment sales were equivalent to last year, with modestly lower North American and improved international sales.

“For the fourth quarter, GAAP operating income was 8.3% of sales, and 9.4% on an adjusted basis(1). For the year, GAAP operating income was 9.7% of sales, and 10.1% on an adjusted basis(1).”

Fourth Quarter Segment Review

Infrastructure-related

Engineered Support Structures (32% of Sales)

Poles, towers and components for the global lighting, traffic and wireless communication markets, and highway safety products.

Sales of $216.5 million were 12% higher than last year as a result of improved wireless communication product sales in North America and the Asia Pacific region. In North America, sales of lighting and traffic products were comparable with last year.

In Europe, sales of lighting and traffic structures were similar to last year as general economic conditions are limiting growth in infrastructure investment.

Operating income was $16.6 million or 7.7% of sales ($19.2 million and 8.9% adjusted(1)) compared to $13.9 million, or 7.2% of sales in 2015 ($18.0 million and 9.3% adjusted(1)). Higher steel costs during the quarter modestly pressured margins in the segment.

Utility Support Structures (27% of Sales)

Steel and concrete structures for the global electric utility industry.

Sales of $185.1 million increased 8.5% year-over-year driven by higher volumes and pricing that rose in-line with higher average steel costs earlier in the year. The ongoing needs to improve grid reliability and interconnect regional transmission grids are supporting market growth.

Operating income increased to $20.8 million or 11.2% of sales, compared to a loss of $2.4 million in 2015 ($16.2 million and 9.5% adjusted(1)), benefitting from higher volume, operational leverage, improved pricing and productivity improvements.

Coatings Segment (11% of Sales)

Global galvanizing, painting and anodizing services.

Sales of $75.5 million were equal to last year. Higher sales in the Asia-Pacific region offset lower North American sales, where sales to external customers were lower than last year, largely due to weaker demand in the alternative energy markets. Sales to other Valmont segments helped to partly offset lower external volumes.

Operating income was $9.5 million, or 12.5% of sales, ($9.8 million and 13.0% adjusted(1)) compared to $5.4 million, or 7.1% of sales in 2015 ($12.9 million and 17.0% adjusted(1)). In North America, in addition to lower volumes, the sales mix was unfavorable with greater internal sales. Rising zinc costs pressured margins as price recovery lagged somewhat. Included in Q4 results were startup costs associated with a new facility in Texas.

Energy and Mining Segment (13% of Sales)

Offshore structures, engineered access systems and grinding media.

Segment sales of $87.9 million were 12% higher than last year with gains across the major product lines. Offshore wind structures and component sales helped offset continued soft demand for oil and gas exploration structures. Access systems sales increased led by improved sales into architectural and construction markets in Australia. Grinding media demand increased partly due to customer purchase patterns in light of rising steel costs.

Operating income increased to $2.7 million or 3.0% of sales ($6.2 million and 7.1% adjusted(1)) compared to a loss of $21.5 million in 2015, (operating income of $0.5 million and 0.6% adjusted(1)). The increase was driven by improved operating performance, in part due to restructuring actions, as well as higher sales.

Agriculture-related

Irrigation Segment (20% of Sales)

Agricultural irrigation equipment, parts, services and tubular products.

Global sales of $136.6 million were similar to last year. In North America, sales declined modestly. International sales rose, led by a stronger Latin American market. Tubing sales were similar to last year.

Operating income was higher at $17.1 million, or 12.5% of sales ($17.5 million and 12.8% adjusted(1)) compared to $8.3 million, or 6.0% of sales in 2015 ($16.2 million and 11.8% adjusted(1)).The improvement in operating income was largely due to the contribution of stronger international results and lower SG&A.

2017 Outlook:

For 2017, the company is issuing annual guidance for diluted EPS to increase approximately 10% from adjusted EPS(1) of $6.42.

Assumptions:

·                  Revenue growth — mid single digit with each segment expecting positive comparisons

·                  Raw material costs — up early in year, moderate later

·                  Foreign exchange translation effects minor

·                  Tax rate of 31%

“We expect to meet all of our financial goals as outlined at our February 2016 investor day,” Mr. Bay said. “For 2017, revenue should grow around 5% without acquisitions. While EPS is expected to decrease on a GAAP basis from $7.63, we expect 10% growth over the $6.42 adjusted result. We also expect to meet or exceed our 10% return on invested capital and more than one-time free cash flow conversion targets.”

The backlog of orders for the principal products manufactured and marketed was $602 million at the end of fiscal 2016 and $591 million at the end of the 2015 fiscal year. We anticipate that most of the backlog of orders will be filled during fiscal year 2017. At year-end, the segments with backlog were as follows (dollar amounts in millions):

Valmont has aggregated its business segments into five reportable segments as follows.

Engineered Support Structures: This segment consists of the manufacture of engineered  structures and components for global lighting and traffic, wireless communication, and roadway safety.

Energy and Mining: This segment includes the manufacture of access systems applications, forged steel grinding media, and offshore oil and gas and wind energy structures.

Utility Support Structures: This segment consists of the manufacture of engineered steel and concrete structures for the global utility industry.

Coatings: This segment consists of global galvanizing, painting and anodizing services.

SUMMARY OF EFFECT OF SIGNIFICANT NON-RECURRING ITEMS ON REPORTED RESULTS

REGULATION G RECONCILIATION

(Dollars in thousands, except per share amounts)

(unaudited)

The non-GAAP tables below disclose the impact on (a) diluted earnings per share of (1) restructuring costs, (2) deferred income tax (benefit) expense arising from changes in foreign tax rates and an international legal reorganization (3) goodwill and trade name impairment charges, and (4) other non-recurring expenses (including the reversal of a contingent liability), and (b) segment operating income of restructuring costs, impairments, and non-recurring expenses. Amounts may be impacted by rounding. We believe it is useful when considering company performance for the non-GAAP adjusted net earnings and operating income to be taken into consideration by management and investors with the related reported GAAP measures as a number of non-recurring transactions were recognized in 2016 and 2015, some of which are non-cash.

* Other non-recurring charges (pre-tax) in 2015 are the $17,000 provision for a Utility commercial settlement and the $7,010 recognized allowance for doubtful China receivable (Irrigation).

** The tax effect of adjustments is calculated based on the income tax rate in each applicable jurisdiction, except the reversal of the contingent liability in 2016 and the impairment of goodwill, both of which are not taxable.

***The $7,120 of deferred income tax expense is due to a 2% decrease in the U.K. corporate tax rate in 2015.
