Non-GAAP Rationale Non-GAAP Rationale Non-GAAP operating profit or loss (operating profit or loss according to accounting principles generally accepted in the United States excluding pre-tax severance, impairment and other associated costs; pre-tax non-cash stock-based compensation expenses; and other pre-tax adjustments as described in the applicable period), non-GAAP diluted earnings (loss) per share (net earnings (loss) per share from continuing operations according to principles generally accepted in the United States excluding after-tax severance, impairment and other associated costs; after-tax non-cash stock-based compensation expenses; and other after-tax adjustments as described in the applicable period) and adjusted EBITDA (net earnings attributable to Pulse Electronics Corporation plus net earnings from discontinued operations and non-controlling interest, excluding income taxes; depreciation and amortization; interest expense/income; non-cash stock-based compensation expenses; other expense/income; and severance, impairment and other associated costs and other adjustments as described in the applicable period), are not measures of performance under accounting principles generally accepted in the United States. Non-GAAP operating profit or loss, non-GAAP diluted earnings (loss) per share and adjusted EBITDA should not be considered a substitute for, and an investor should also consider, net income, operating profit, cash flow from operations and other measures of performance as defined by accounting principles generally accepted in the United States as indicators of our profitability or liquidity. Non-GAAP operating profit (loss) and non-GAAP diluted earnings (loss) per share are often used by our shareholders and analysts as an additional measure of our operating performance. Adjusted EBITDA is often used by our shareholders and analysts as an indicator of a company’s ability to service debt and fund capital expenditures. We believe these non-GAAP measures enhance a reader’s understanding of our financial condition, results of operations and cash flow because they are unaffected by capital structure and, therefore, enables investors to compare our operating performance to that of other companies. We understand that our presentation of non-GAAP operating profit (loss), non-GAAP diluted earnings (loss) per share and adjusted EBITDA may not be comparable to other similarly titled captions of other companies due to differences in the method of calculation. Based on discussions with investors and equity analysts, we believe that a reader’s understanding of the Company’s operating performance is enhanced by references to these non-GAAP measures. Removing charges for severance, impairment and other associated costs, non-cash stock-based compensation expenses and other adjustments may facilitate comparisons of operating performance among financial periods and peer companies. These charges result from facility closures, the exit of a product line, production relocations and capacity reductions and / or restructuring of overhead and operating expenses to enhance or maintain profitability in an increasingly competitive environment. Removing non-cash stock-based compensation expenses facilitates comparisons of the company’s operating performance with that of other companies with differing compensation structures and with the company’s performance in periods during which its own compensation structure may have been different. Impairment charges, accelerated depreciation and costs related to an unsolicited takeover attempt are not part of the normal operating expense structure of the relevant business in the period in which the charge is recorded.
