WILMINGTON, Del. October 29, 2026 - InterDigital, Inc. (Nasdaq: IDCC), a wireless, video, and AI technology research and development company, today announced results for the quarter ended September 30, 2026.

“This was another excellent quarter, with double-digit growth in revenue and profitability and record annualized recurring revenue,” said Liren Chen, President and CEO of InterDigital. “We secured a new PC license through arbitration and advanced our video services program. Building on last quarter’s increase in annual guidance, our strong execution in Q3 supports another increase to the midpoint of our full-year revenue guidance, this time based only on revenue already under contract.

•Signed new IoT license agreement with EV charging company KEBA

•Earned revenue of $193 million up 17% year-over-year

•Achieved record annualized recurring revenue of $629 million

•Declared increase in quarterly cash dividend from $0.70 to $0.75 per share

•Awarded two new injunctions against Disney by Europe’s Unified Patent Court; in total eight injunctions won against Disney out of eight patent cases decided to date

Convertibility of 2027 Notes

Pursuant to the terms of the Indenture governing InterDigital’s 3.50% Senior Convertible Notes due 2027 (the “Notes”), the Notes are convertible during the calendar quarter ending December 31, 2026. The current conversion rate of the Notes is 13.0351 shares of InterDigital’s Common Stock per $1,000 principal amount of the Notes.

Upon the conversion of any Notes, InterDigital will pay cash up to the aggregate principal amount of the Notes to be converted, and will pay cash, shares of its Common Stock or a combination of cash and shares of its Common Stock for any conversion obligation in excess of the aggregate principal amount being converted, if any, at InterDigital’s election, as set forth in the Indenture governing the Notes.

At the time InterDigital issued the Notes, InterDigital entered into call spread transactions that together were designed to have the economic effect of reducing the net number of shares that will be issued in the event of conversion of the Notes by, in effect, increasing the conversion price of the Notes from InterDigital’s economic standpoint from $76.72 to $105.30. In connection with the Notes issuance, we also issued warrants to acquire, subject to customary anti-dilution adjustments, approximately 6.0 million shares of common stock. Refer to "Management's Discussion and Analysis of Financial Condition and Results of Operations - Notes, Hedge, and Warrant Transactions" in InterDigital’s Form 10-Q for the quarter ended September 30, 2026 for more information.

As of September 30, 2026, $296.7 million in principal of the 2027 Notes remains outstanding, of which holders have elected to convert $2.2 million principal amount, which will settle in fourth quarter 2026. No incremental outstanding shares will result from such conversions due to the offsetting impact of hedging arrangements.

As of September 30, 2026, warrants to acquire 6.0 million shares of common stock remain outstanding at a strike price of $105.30, subject to adjustment, which mature on a net-share basis beginning September 2027 through April 2028.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Such statements include information regarding our current beliefs, plans and expectations. Words such as “believe,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “forecast,” "outlook," “goal,” “could,” "would," "should," "if," "may," "might," "future," "target," "trend," "seek to," "will continue," "predict," "likely," "in the event," and variations of any such words or similar expressions are intended to identify such forward-looking statements.

Forward-looking statements are made on the basis of management’s current views and assumptions and are not guarantees of future performance. Forward-looking statements, including but not limited to statements regarding our outlook for Q4 and full year 2026, are inherently subject to risks and uncertainties that could cause actual results, and actual events that occur, to differ materially from results contemplated by the forward-looking statements. These risks and uncertainties include, but are not limited to: (i) unanticipated delays or difficulties in the execution of patent license agreements on acceptable terms or at all; (ii) our ability to expand our revenue opportunities by entering into licensing arrangements with streaming and cloud-based service providers; (iii) the initiation of new legal proceedings or the resolution of ongoing legal proceedings, including any awards or judgments relating to such proceedings, and changes in the schedules or costs associated therewith; (iv) our ability to maintain a strong patent portfolio and make strategic decisions related to our intellectual property protection; (v) our ability to successfully integrate Deep Render and to recognize the anticipated benefits of the transaction; (vi) the failure of markets for our technologies to materialize to the extent that we expect; (vii) our continued ability to develop new technologies; (viii) changes in our interpretations of, and assumptions and calculations with respect to the impact on us of, the One Big Beautiful Bill Act, the 2017 Tax Cuts and Jobs Act and other U.S. and non-U.S. tax laws and other tax matters; (ix) the timing and impact of potential regulatory, administrative and legislative matters; (x) the potential effects of macroeconomic conditions or global conflicts; (xi) our ability to hire and retain key personnel; (xii) operational risks, including cybersecurity events, human failures or other difficulties with our information technology systems; and (xiii) risks related to any new accounting standards or our estimates, assumptions and the application of relevant accounting standards, including with respect to revenue recognition.

Footnotes

1 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 not 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 measures used by other companies.

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 plus income tax provision, other income, net & 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 titled 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 reconciliation of Adjusted EBITDA to the most directly comparable GAAP financial measure is provided below.

3 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 provide investors with important insight into the Company's ongoing business performance. InterDigital defines Non-GAAP net income as net income plus share-based compensation, acquisition related 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. 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 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. A reconciliation of each of these metrics to its most directly comparable GAAP financial measure is provided below.

42 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 not 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 measures used by other companies. 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 benefit (provision), other income, net & 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 titled 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 reconciliation of Adjusted EBITDA to 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 provide 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, 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 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. A reconciliation of each of these metrics to its 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 measure 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 capital expenditures and capitalized patent costs. InterDigital’s computation of free cash flow 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 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 reconciliation of free cash flow to net cash provided by (used in) operating activities, the most directly comparable GAAP financial measure, is provided below. ©2026 InterDigital, Inc.
