48©2026 InterDigital, Inc. All Rights Reserved. Supplemental Metrics Annualized recurring revenue ("ARR") for any quarter is defined as total revenue for the quarter less catch -up revenue for the quarter, multiplied by four. Management believes ARR provides useful information about our financial performance, and our progress toward our 2030 targets. ARR is no t a projection or forecast, and actual recurring revenue for any 12-month period will depend on a number of factors beyond our ability to predict or control, including those risks and uncertainties listed above. Additionally, ARR may be calculated differently from, and therefore may not be comparable to, similarly titled measure s used by other companies. Adjusted EBITDA and Adjusted EBITDA margin are supplemental non -GAAP financial measures that InterDigital believes provide inves tors with important insight into the Company's ongoing business performance. InterDigital defines Adjusted EBITDA as net income attributable to InterDigital Inc. plu s 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 revenue. These non-GAAP financial measures used by the company may be calculated differently from, and therefore may not be comparable to, similarly tit led measures used 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. A re conciliation of Adjusted EBITDA to the most directly comparable GAAP financial measure is provided below. Free cash flow is a supplemental non-GAAP financial measure that InterDigital believes is helpful in evaluating the company’s ability to invest in its business, make strategic acquisitions and fund share repurchases, among other things. A limitation of the utility of free cash flow as a mea sure of financial performance is that it does not represent the total increase or decrease in the company’s cash balance for the period. InterDigital defines free cash flow as net cash provided by (used in) operating activities less purchases of property and equipment and capitalized patent costs. InterDigital’s computation of free cash flo w might not be comparable to free cash flow reported by other companies. The presentation of free cash flow, which is not prepared under any comprehensive set of account ing 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. A reconciliation of free cash flow to net cash used in operating activities, the most directly comparable GAAP financial measure, is provided below. Non-GAAP net income, Non-GAAP earnings per share (“EPS”), and Non-GAAP weighted-average diluted shares 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 as net income attributable to InterDigital, Inc. plus share-based compensation, acquisition related amortization, depreciation and amortizatio n, 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. Non- GAAP EPS is defined as Non-GAAP net income divided by Non-GAAP weighted-average diluted shares, which adjusts the weighted average number of common shares outstanding for the dilutive effect of the Company's convertible notes, offset by our hedging arrangements. InterDigital’s co mputation of these non-GAAP financial measures might not be comparable to similarly named measures reported by other companies. The presentation of these financial me asures, which are not prepared under any comprehensive set of accounting rules or principles, is not intended to be considered in isolation or as a substitu te for the financial information prepared and presented in accordance with GAAP. A reconciliation of each of these metrics to its most directly comparable GAAP financial m easure is provided below.
