APPENDIX A Adjusted EBITDA and Adjusted EBITDA margin are supplemental non-GAAPfinancial 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-controllinginterest, 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-recurringitems. Adjusted EBITDA margin is adjusted EBITDA over total revenues. These non-GAAPfinancial measures 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 and adjusted EBITDA margin to the most directly comparable GAAP financial measure is provided below.
