Regulation G Reconciliation of GAAP to NON-GAAP Financial Measures LINDSAY CORPORATION AND SUBSIDIARIES RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES (Unaudited) The non-GAAP tables below disclose (a) the impact on diluted earnings per share of (1) tax expense attributed to enactment of the U.S. Tax Cuts and Jobs Act ("U.S. Tax Reform"), and (2) severance costs and professional consulting fees associated with the Company's Foundation for Growth initiative ("FFG costs"), (b) the impact on operating income of FFG costs, and (c) the impact on segment operating income of FFG costs. Management believes adjusted net earnings, adjusted diluted earnings per share and adjusted operating income are important indicators of the Company’s business performance because they exclude items that may not be indicative of, or may be unrelated to, the Company’s underlying operating results, and provide a useful baseline for analyzing trends in the business. Non-GAAP measures used by the Company may differ from similar measures used by other companies, even when similar terms are used to identify such measures. These adjusted financial measures should not be considered in isolation or as a substitute for reported net earnings, diluted earnings per share and operating income. These non-GAAP financial measures reflect an additional way of viewing the Company’s operations that, when viewed with the GAAP results and the following reconciliations to the corresponding GAAP financial measures, management believes provides a more complete understanding of the Company’s business.
