Use of Non-GAAP Financial Measures

This press release contains financial measures, including EBITDA and earnings per share, which are considered “non-GAAP” financial measures under applicable Securities and Exchange Commission rules and regulations. These non-GAAP financial measures should be considered supplemental to and not a substitute for financial information prepared in accordance with generally accepted accounting principles. The Company’s definition of these non-GAAP measures may differ from similarly titled measures used by others.

The Company defines EBITDA as Operating Income plus Depreciation and Amortization before adjustments divided by Net Sales. The non-GAAP financial measures used in this press release adjust for specified items that can be highly variable or difficult to predict. The Company generally uses these non-GAAP financial measures to facilitate management’s financial and operational decision-making, including evaluation of HARMAN’s historical operating results, comparison to competitors’ operating results and determination of management incentive compensation. These non-GAAP financial measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to corresponding GAAP financial measures, may provide a more complete understanding of factors and trends affecting the Company’s business.

Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety.

This earnings release also makes reference to the Company’s awarded business, which represents the estimated future lifetime net sales for all customers. The Company’s future awarded business does not represent firm customer orders. The Company reports its awarded business primarily based on written award letters from our customers. To validate these awards, the Company uses various assumptions including global vehicle production forecasts, customer take rates for the Company’s products, revisions to product life cycle estimates and the impact of annual price reductions and exchange rates, among other factors. These assumptions are updated and reported externally on an annual basis. The Company updates the estimates and awarded business quarterly by adding the value of new awards received and subtracting sales recorded during the quarter. These quarterly updates do not include any assumptions for increased take rates, revisions to product life cycle, or any other factors.
