Reg G Reconciliation VALMONT INDUSTRIES, INC. AND SUBSIDIARIES SUMMARY OF EFFECT OF SIGNIFICANT NON-RECURRING ITEMS ON REPORTED RESULTS (Dollars in thousands, except per share amounts) (unaudited) The non-GAAP tables below disclose the impact on (a) diluted earnings per share of (1) tax expense attributed to the Tax Cuts and Job Act ("2017 Tax Act"), (2) restructuring costs, (3) deferred income tax (benefit) expense arising from changes in foreign tax rates and an international legal reorganization 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 2017 and 2016, some of which are non-cash.

Reconciliation of Adjusted EBITDA to GAAP Figures Earnings before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA) is one of our key financial ratios in that it is the basis for determining our maximum borrowing capacity at any one time. We calculate "Further Adjusted EBITDA" by adding back cash restructuring and non-recurring expenses to Adjusted EBITDA, as management finds these alternate measures of EBITDA useful to the company's performance from different aspects, and we believe investors will also. 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 Net earnings attributable to Valmont Industries, Inc.

Our measure of Free Cash Flow may not be directly comparable to similar measures used by other companies. 2013 2014 2015 2016 2017 Net Cash Flows from Operations Purchase of Plant, Property, and Equipment Free Cash Flows $ 396,442 $ 174,096 $ 272,267 $ 219,168 $ 145,716 (106,753) (73,023) (45,468) (57,920) (55,266) $ 289,689 $ 101,073 $ 226,799 $ 161,248 $ 90,450 Net Earnings Attributed to Valmont Industries, Inc. $ 278,489 $ 183,976 $ 40,117 $ 173,232 $ 116,240 Adjusted Net Earnings Attributed to Valmont Industries, Inc.

Calculation of Return on Invested Capital Return on Invested Capital is calculated as Operating Income (after-tax) divided by the average of beginning and ending Invested Capital. Invested Capital represents total assets minus total liabilities (excluding interest-bearing debt). Return on Invested Capital is one of our key operating ratios, as it allows investors to analyze our operating performance in light of the amount of investment required to generate our operating profit. Return on Invested Capital is also a measurement used to determine management incentives. Return on Invested Capital is a non-GAAP measure. Accordingly, Invested Capital and Return on Invested Capital should not be considered in isolation or as a substitute for net earnings, cash flows from operations or other income or cash flow data prepared in accordance with GAAP or as a measure of our operating performance or liquidity. The table below shows how Invested Capital and Return on Invested Capital are calculated from our income statement and balance sheet. 2017 2016 Operating Income Adjusted Effective Tax Rate Tax Effect on Operating Income After-tax Operating Income Average Invested Capital Return on Invested Capital Total Assets Less: Accounts and Income Taxes Payable Less: Accrued Expenses Less: Defined Benefit Pension Liability Less: Deferred Compensation Less: Other Noncurrent Liabilities Less: Dividends Payable Total Invested Capital Beginning of Year Invested Capital Average Invested Capital $ 266,432 28.1% 74,867 $ 243,504 30.8% 74,999 191,565 168,505 $ 1,858,249 10.3% 2,602,250 (227,906) (165,455) (189,552) (48,526) (20,585) (8,510) $ 1,767,316 9.5% 2,391,731 (177,488) (162,318) (209,470) (44,319) (14,910) (8,445) $ $ 1,941,716 1,774,781 $ 1,774,781 $ 1,759,851 $ 1,858,249 $ 1,767,316 1 The adjusted tax for 2017 excludes the $41,935 of tax expense associated with the 2017 Tax Act. The effective tax rate in 2017 including these items is 46.5% Fiscal 2016 also excludes the reversal of a contingent liability that was recognized as part of the Delta purchase accounting of $16,591, which is not taxable. The effective tax rate in 2016 including these items is 19.1%. 130 | March 6, 2018 | Valmont Industries, Inc.

Calculation of Annual Total Value Impact (TVI) TVI is calculated as Operating Income (after-tax) less 8.5% times the average of beginning and ending Invested Capital. Invested Capital represents total assets minus total liabilities (excluding interest-bearing debt).
