Concerning Forward-Looking Statements

This release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on assumptions made by management, considering its experience in the industries where Valmont operates, perceptions of historical trends, current conditions, expected future developments, and other relevant factors. It is important to note that these statements are not guarantees of future performance or results. They involve risks, uncertainties (some of which are beyond Valmont's control), and assumptions. While management believes these forward-looking statements are based on reasonable assumptions, numerous factors could cause actual results to differ materially from those anticipated. These factors include, among other things, risks described in Valmont's reports to the Securities and Exchange Commission ("SEC"), the Company's actual cash flows and net income, future economic and market circumstances, industry conditions, company performance and financial results, operational efficiencies, availability and price of raw materials, availability and market acceptance of new products, product pricing, domestic and international competitive environments, geopolitical risks, and actions and policy changes by domestic and foreign governments, including tariffs. The Company cautions that any forward-looking statements in this release are made as of its publication date and does not undertake to update these statements, except as required by law.

The Company may provide certain non-GAAP financial measures (adjusted diluted earnings per share and adjusted effective tax rate) on a forward-looking basis from time to time. These measures are typically calculated by excluding the impact of items such as foreign exchange, acquisitions, divestitures, realignment or restructuring expenses, goodwill or intangible asset impairment, changes in tax laws or rates, change in redemption value of redeemable noncontrolling interests, and other non-recurring items. To the extent the Company provide forward-looking non-GAAP financial measures, reconciliations to the most directly comparable GAAP financial measures are not provided, as the Company cannot do so without unreasonable effort due to the inherent uncertainty and difficulty in predicting the timing and financial impact of such items. For the same reasons, the Company cannot assess the likely significance of unavailable information, which could be material to future results.

Website and Social Media Disclosure

The Company uses its website and social media channels, as identified on its website, to distribute company information. Posts on these channels may contain material information. Therefore, investors should monitor these channels alongside the Company's press releases, SEC filings, and public conference calls and webcasts. The contents of the Company's website and social media channels are not considered part of this press release.
