1        Throughout this press release, net income and diluted earnings per share (“EPS”) are attributable to InterDigital, Inc. (e.g., after adjustments for non-controlling interests), unless otherwise stated.

2        Adjusted EBITDA and Adjusted EBITDA margin are supplemental non-GAAP financial measures that InterDigital believes provide investors with important insight into the company's ongoing business performance. InterDigital defines Adjusted EBITDA as net income attributable to InterDigital Inc. plus net loss attributable to non-controlling interest, income tax (provision) benefit, other income (expense) & interest expense, depreciation and amortization, share-based compensation, and other items. Other items include restructuring costs, impairment charges and other non-recurring items. Adjusted EBITDA margin is Adjusted EBITDA over total revenues. These non-GAAP financial measures used by the company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. A detailed reconciliation of Adjusted EBITDA to the most directly comparable GAAP financial measure is provided below.

3        Non-GAAP net income and Non-GAAP diluted EPS are supplemental non-GAAP financial measures that InterDigital believes provides investors with important insight into the company's ongoing business performance. InterDigital defines non-GAAP net income attributable to InterDigital, Inc. as net income plus share-based compensation, acquisition related amortization, depreciation and amortization, restructuring costs, impairment charges and one-time adjustments, losses on extinguishments of long-term debt, the related income tax effect of the preceding items, and adjustments to income taxes. InterDigital’s computation of these non-GAAP financial measures might not be comparable to similarly named measures reported by other companies. The presentation of these financial measures, which are not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.
