Adjusted Infrastructure Operating Income – Including Reconciliation of GAAP to Non-GAAP April 6, 2022 | Valmont Industries, Inc.5 The non-GAAP tables below disclose the impact of 1) the impairment of long-lived assets 2) a write off of a receivable following arbitration of a commercial transaction from 2014, 3) 2020 restructuring activates including related asset impairments, and 4) severance expenses on the Infrastructure segment operating income. 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. Agriculture is a renaming of the previous Irrigation segment so historical results, and historical presentation of non-GAAP results, will not change Operating Income Reconciliation Q1 2021 Q2 2021 Q3 2021 Q4 2021 Fiscal 2021 Fiscal 2020 Operating income - as reported 54,449 61,550 71,422 45,985 233,406 209,172 Impairment of long-lived assets - - - 27,911 27,911 16,638 Write-off of a receivable, pre-tax - 5,545 - - 5,545 - Restructuring and related asset impairment costs - - - - - 20,898 Severance expense, pre-tax - 650 - 2,492 3,142 - Adjusted Operating Income 54,449$ 67,745$ 71,422$ 76,388$ 270,004$ 246,708$ Sales, before intersegment elims. - as reported 549,646$ 617,604 634,283 693,568 2,495,101 2,261,804 Operating Income as a % of Sales 9.9% 10.0% 11.3% 6.6% 9.4% 9.2% Adjusted Operating Income as a % of Sales 9.9% 11.0% 11.3% 11.0% 10.8% 10.9% Infrastructure Segment
