INTERDIGITAL ANNOUNCES FINANCIAL RESULTS FOR FIRST QUARTER 2026

Revenue, Adjusted EBITDA1 and EPS above top end of guidance

New agreements drive record Smartphone ARR2

Company reaffirms full year 2026 guidance

WILMINGTON, Del. April 30, 2026 - InterDigital, Inc. (Nasdaq: IDCC), a wireless, video, and AI technology research and development company, today announced results for the quarter ended March 31, 2026.

"With six new agreements in the first quarter, including renewing Xiaomi to a long-term contract, we are off to a strong start in 2026. These new agreements drove our results above the top-end of our guidance as we continued our momentum across our licensing programs, our research and innovation pipeline, and our patent portfolio", commented CEO Liren Chen. "Over the last five years, we have signed agreements with a cumulative total contract value of $4.7 billion and now have the world's top-three smartphone vendors under license through the end of the decade. This success provides a strong base from which to drive additional growth."

Business Highlights for First Quarter 2026

•Signed six new agreements in Q1, including a renewal with Xiaomi and a new license with LG Electronics covering TVs & computer displays

•Annualized recurring revenue2 ("ARR") increased 13% year-over-year from $502.9 million to $567.2 million

•Smartphone ARR increased 18% year-over-year to an all-time high of $491.8 million

•Ranked by the European Patent Office among top five US companies in 2025 for patent applications

•Awarded fifth injunction against Disney by a court in Germany

•A court in Brazil found our licensing offer to be FRAND and awarded an injunction against Transsion

•Promoted to the S&P MidCap 400 from the S&P SmallCap 600

•Recognized by LexisNexis as one of the world’s 100 most innovative companies fifth year in a row

First Quarter 2026 Financial Summary:

First quarter 2026 revenue included $63.6 million of catch-up revenue, compared with $84.8 million in first quarter 2025. Operating expenses increased $44.5 million primarily due to an increase in revenue share costs driven by the LG TV agreement and an increase in intellectual property enforcement costs.

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 its calendar quarter ending June 30, 2026. The current conversion rate of the Notes is 12.9041 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 $77.49 to $105.55. 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 March 31, 2026 for more information.

In December 2025, holders elected to convert $80.0 million principal amount of the 2027 Notes, which was settled in the first quarter of 2026. We paid the $80.0 million principal amount in cash and issued 0.8 million shares to settle the conversion spread. These shares issued were offset by 0.8 million shares received upon partial settlement of the 2027 Note Hedge Transactions, resulting in no incremental outstanding shares resulting from the conversion.

As of March 31, 2026, 6.0 million warrants remain outstanding related to the 2027 Warrant Transactions at a weighted-average strike price of $105.55 per share, subject to adjustment, which mature on a net-share basis beginning September 2027 through April 2028.

Near Term Outlook

The Company has reaffirmed its full year 2026 outlook and provided an initial outlook for the second quarter 2026. The outlook for second quarter 2026 covers existing licenses and does not include any new agreements or enforcement action results we may sign or receive over the balance of the second quarter. The outlook for full year 2026 includes both existing licenses and the expected contributions from new agreements and/or enforcement actions we may receive over the balance of the year.

Forward-looking statements are made on the basis of management’s current views and assumptions and are not guarantees of future performance.

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 assumptions and application of relevant accounting standards, including with respect to revenue recognition.

Footnotes

1    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) benefit, 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.

2    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.

3    Non-GAAP net income, Non-GAAP 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 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.

43 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 (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 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 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, 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. ©2026 InterDigital, Inc. All Rights Reserved.
