Reconciliation of Excluding Other Segment Net Sales Dollars in thousands 32 Excluding Other segment net sales from the third quarter and first three quarters of fiscal 2022, which we refer to in this reconciliation as “Adjusted Net Sales” is a non-GAAP measure. The Other segment net sales were generated by the wind energy structures business which was divested in December 2022. Adjusted Net Sales 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 Adjusted Net Sales is calculated from our statements of earnings. Adjusted Net Sales is calculated as Net Sales less Other segment net sales. Adjusted Net Sales allows investors to analyze our operating performance in light of the amount of net sales less net sales of a divested business.

Adjusted Effective Tax Rate should not be considered in isolation or as a substitute for the effective tax rate prepared in accordance with GAAP. The table below shows how Adjusted Effective Tax Rate is calculated from the Company’s Statements of Operations. Adjusted Effective Tax Rate is calculated as total earnings (loss) before income taxes plus the significant non-recurring items of impairment of goodwill and intangible assets, realignment charges, and non-recurring tax benefit items. Adjusted Effective Tax Rate allows investors to analyze our effective tax rate in light of these non-recurring items.

34 1 Adjusted earnings for purposes of calculating FCF conversion may not agree to the adjusted net earnings. The difference is due to non-recurring expenses which were settled in cash in the year of occurrence as part of net cash flows from operating activities. 2 We use the non-GAAP measure of FCF, which we define as GAAP net cash flows from operating activities reduced by capex. We believe that FCF is a useful performance measure for management and useful to investors as the basis for comparing our performance with other companies.
