Omaha, United States of America – First Quarter Highlights:

Omaha, NE – Valmont Industries, Inc. (NYSE: VMI), a leading global manufacturer of engineered support structures for infrastructure, mechanized irrigation equipment for agriculture, and a provider of coating services and tubular products, reported first quarter sales of $303.6 million compared with $265.7 million for the same period of 2005. First quarter 2006 net earnings were $13.1 million, or 52 cents per diluted share, versus first quarter 2005 net earnings of $6.8 million, or 27 cents per diluted share. Miscellaneous income includes a one-time gain of $1.1 million related to a discontinued retirement plan of a former subsidiary.

First Quarter Review:
"Solid demand from utility customers, improved industrial demand for galvanizing and a stronger irrigation selling season, were the major factors driving record first quarter sales and earnings," said Mogens C. Bay, Valmont’s Chairman and Chief Executive Officer. "In the Engineered Support Structures Segment, improvement came primarily from international growth.

"We are making good progress in our drive to increase operating income as a percent of sales, with improvements in every segment led by the Coatings, Utility Support Structures and Irrigation segments.

"The impact of expensing stock options starting in 2006 will result in an increase in selling, general and administrative expenses of approximately $1.5 million spread out over four quarters. Higher corporate expenses also reflect increased incentive accruals resulting from the strong gains in net earnings.

"Strong operating performance contributed to net earnings growing 92% on a 14% increase in sales and lower levels of debt reduced interest expense."

First Quarter Summary – Infrastructure Markets:
Sales in the Engineered Support Structures Segment were $115.5 million, an increase of 6% from 2005 levels. Operating income for the segment increased 25% to $7.0 million. Most of the gains came from China and Europe.

Global sales of lighting and traffic products were higher led by increases in Europe. The success of a highly engineered structure for the tramway market in France continued to contribute to European sales gains.

In China, sales increased as strong wireless communication sales more than offset slightly lower utility and lighting and traffic structure sales. The Company has started manufacturing in its new facility in southern China. Commercial shipments will commence during the second quarter.

North American sales of specialty structures increased in both wireless communication products and sign structures due to improved market conditions.

Utility Support Structures Segment sales increased 12% to $66.2 million compared with $59.0 million in 2005. Operating income was $8.0 million, a sharp increase over last year’s $4.4 million due to increased plant operating efficiencies and a favorable product mix.

The increase in sales reflects both strong spending by utilities on transmission and distribution structures to bolster the reliability of the electrical grid, and reconstruction in hurricane-stricken areas. The 2005 energy bill also provides incentives for utilities to upgrade the transmission grid. Valmont continues to strengthen key alliances with utility customers and, with its steel and concrete manufacturing capabilities, offers a broad structural product range designed to provide optimal solutions to the utility industry.

Coatings Segment sales of $25.3 million were 33% higher than last year’s first quarter and operating income for the segment tripled to $2.4 million compared with $0.8 million in the first quarter of 2005.

Sales volumes increased at every coatings location, reflecting both increased internal demand and an improving industrial economy. The substantial increase in profitability resulted from operating leverage as higher sales led to better absorption of fixed costs. Although zinc prices rose to record high levels, the Company has been able to recover most of the cost increases through pricing.

First Quarter Summary – Agricultural Markets:
In the Irrigation Segment, first quarter sales were $86.9 million, a 24% increase from 2005. Operating income for the segment rose 56% to $11.3 million. The increase in operating income resulted mainly from the higher sales volumes and associated operating leverage due to factory and SG&A expense control.

North American irrigation sales rose due to a stronger winter selling season, increased replacement sales for storm-damaged irrigation equipment and higher selling prices than last year. International sales increased as a result of new market development.

In the Tubing Segment, sales were 6% higher at $23.5 million due to strong market conditions and improved demand from agricultural equipment manufacturers. Operating income increased 11% to $3.6 million reflecting higher sales levels and improved operations.

2006 Outlook:
Commenting on the outlook for the remainder of 2006, Mr. Bay said, "We had a record first quarter with the highest sales and earnings of any quarter in our history. First quarter comparisons were helped by a very weak irrigation market during the first quarter of 2005. While our outlook for the rest of the year is positive, and we expect favorable comparisons for the next three quarters, we do not expect the same rate of profitability improvement as we saw in the first quarter.

"In our structures businesses the markets are showing strength because of the passage of the highway and energy bills in 2005. Our near term outlook is for continued improvements, as backlogs are strong in both the Engineered Support Structures and Utility Support Structures businesses. In the Coatings Segment, we expect sales volumes to reflect economic conditions. In the Irrigation Segment, the current selling season is drawing to a close. The fall selling season to a large extent will be dependent on crop prices and overall farm income. In the Tubing business, we currently expect results to track with the industrial economy and steel price trends.

"While first quarter sales grew 14%, we currently expect fiscal year sales to finish closer to 8-10% above 2005 levels. We are making good progress on our goal to improve operating income as a percent of sales. We would like to see an improvement of about 1 percentage point for the full year."
