NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2026

(unaudited)

1. BASIS OF PRESENTATION

In the opinion of management, the accompanying unaudited, condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the financial position of InterDigital, Inc. (individually and/or collectively with its subsidiaries referred to as “InterDigital,” the “Company,” “we,” “us” or “our,” unless otherwise indicated) as of March 31, 2026, the results of our operations for the three months ended March 31, 2026 and 2025 and our cash flows for the three months ended March 31, 2026 and 2025. The accompanying unaudited, condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, accordingly, do not include all of the detailed schedules, information and notes necessary to state fairly the financial condition, results of operations and cash flows in conformity with United States generally accepted accounting principles (“GAAP”). The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP for year-end financial statements. Therefore, these financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (our “2025 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 5, 2026. Definitions of capitalized terms not defined herein appear within our 2025 Form 10-K. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. We have one reportable segment.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.

Change in Accounting Policies

There have been no material changes or updates to our existing accounting policies from the disclosures included in our 2025 Form 10-K, except as indicated below in "New Accounting Guidance".

Reclassifications

Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

New Accounting Guidance

Accounting Standards Update: Induced Conversions of Convertible Debt Instruments

In November 2024, the FASB issued ASU No. 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments". The amendments in the ASU require disclosures for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. ASU 2024-04 is effective for fiscal years beginning after December 15, 2025, with early adoption allowed. We adopted this guidance as of January 1, 2026, and there was no impact of this adoption on our consolidated financial statements.

Accounting Standards Update: Targeted Improvements to the Accounting for Internal-Use Software

In September 2025, the FASB issued ASU No. 2025-06, "Intangibles—Goodwill and Other Internal-Use Software (Subtopic 350-40)". The amendments in the ASU amend certain aspects of the accounting for and disclosure of software costs under ASC 350-40. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption allowed. We adopted this guidance as of January 1, 2026, and there was no material impact of this adoption on our consolidated financial statements.

Accounting Standards Update: Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in the ASU require disclosures about specific types of expenses included in the expense captions presented on the Consolidated Statements of Income, as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption allowed. We are currently evaluating the impact of adoption on our financial disclosures.

Accounting Standards Update: Interim Reporting (Topic 270): Narrow-Scope Improvements

In December 2025, the FASB issued ASU 2025-11 to amend the guidance in “Interim Reporting” (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. We are currently evaluating the impact of adoption on our consolidated financial statements.

2. REVENUE

Disaggregated Revenue

The following table presents the disaggregation of our revenue for the three months ended March 31, 2026 and 2025 (in thousands):


	Three Months Ended March 31,
	2026		2025		Increase/(Decrease)

Smartphone	$	123,391	$	183,991	$	(60,600)	(33)	%
CE, IoT/Auto	81,891		26,267		55,624		212	%

Catch-up revenue (a), included above	$	63,623	$	84,785	$	(21,162)	(25)	%

(a) Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.

During the three months ended March 31, 2026, we recognized $61.4 million of revenue that had been included in deferred revenue as of the beginning of the period. As of March 31, 2026, we had contract assets of $58.4 million included within "Accounts receivable" and $27.0 million included within "Other non-current assets, net" in the condensed consolidated balance sheet. As of December 31, 2025, we had contract assets of $19.7 million included within "Accounts receivable" and $21.0 million included within "Other non-current assets, net" in the condensed consolidated balance sheet.

Contracted Revenue

Based on contracts signed and committed as of March 31, 2026, we expect to recognize the following revenue from dynamic fixed-fee royalty payments over the term of such contracts (in thousands):


	Revenue (a)
Remainder of 2026	$	393,262
2027	512,557

2029	356,840
2030	220,601
Thereafter	73,758
Total Revenue	$	1,973,787

(a) This table includes estimated revenue related to our Lenovo arbitration. In accordance with ASC 606, this estimate is limited to the amount of revenue we expect to recognize only to the extent we believe it is probable that a subsequent change in the estimate would not result in a significant revenue reversal.

3. CASH, CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS

Cash, Cash Equivalents, and Restricted Cash

Cash, cash equivalents, and restricted cash currently consist of money market and demand accounts. The following table provides a reconciliation of total cash, cash equivalents, and restricted cash as of March 31, 2026, December 31, 2025, and March 31, 2025 to the captions within the condensed consolidated balance sheets and condensed consolidated statements of cash flows (in thousands):


	March 31,		December 31,		March 31,
	2026		2025		2025
Cash and cash equivalents	$	607,599	$	738,960	$	536,639
Restricted cash included within prepaid and other current assets	9,991		15,308		11,476

Total cash, cash equivalents, and restricted cash	$	617,590	$	754,268	$	548,115

Concentration of Credit Risk and Fair Value of Financial Instruments

Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We place our cash equivalents and short-term investments only in highly rated financial instruments and in United States government instruments.

Our accounts receivable and contract assets are derived principally from patent license and technology solutions agreements. Three licensees comprised 81% and 55% of our accounts receivable balances as of March 31, 2026 and December 31, 2025, respectively. We perform ongoing credit evaluations of our licensees, who generally include large, multinational, wireless telecommunications and consumer electronics equipment manufacturers. We believe that the book values of our financial instruments approximate their fair values.

Fair Value Measurements

We use various valuation techniques and assumptions when measuring the fair value of our assets and liabilities. We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. This guidance established a hierarchy that prioritizes fair value measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below:

Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets.

Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates.

Table of Contents

Level 3 Inputs — Level 3 includes financial instruments for which fair value is derived from valuation techniques including pricing models and discounted cash flow models in which one or more significant inputs are unobservable, including the Company’s own assumptions. The pricing models incorporate transaction details such as contractual terms, maturity and, in certain instances, timing and amount of future cash flows, as well as assumptions related to liquidity and credit valuation adjustments of marketplace participants.

Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial assets and financial liabilities and their placement within the fair value hierarchy. We use quoted market prices for similar assets to estimate the fair value of our Level 2 investments.

Recurring Fair Value Measurements

Our financial assets are generally included within short-term investments on our condensed consolidated balance sheets, unless otherwise indicated. Our financial assets and liabilities that are accounted for at fair value on a recurring basis are presented in the tables below as of March 31, 2026 and December 31, 2025 (in thousands):

5. OBLIGATIONS

2027 Notes and Related Note Hedge and Warrant Transactions

On May 27, 2022, we issued $460.0 million in aggregate principal amount of 3.50% Senior Convertible Notes due in 2027 (the "2027 Notes"). The net proceeds from the issuance of the 2027 Notes, after deducting the initial purchasers' transaction fees and offering expenses, were approximately $450.0 million. The 2027 Notes bear interest at a rate of 3.50% per year, payable in cash on June 1 and December 1 of each year, commencing on December 1, 2022, and mature on June 1, 2027, unless earlier redeemed, converted or repurchased.

The 2027 Notes will be convertible into cash up to the aggregate principal amount of the 2027 Notes to be converted and in respect of the remainder, if any, of the Company’s obligation in excess of the aggregate principal amount of the 2027 Notes being converted, pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination thereof, at the Company’s election, at an initial conversion rate of 12.9041 shares of common stock per $1,000 principal amount of the 2027 Notes (which is equivalent to an initial conversion price of approximately $77.49 per share). From the period January 1, 2024 through June 30, 2026, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes. As such, the 2027 Notes are included in "Current portion of long-term debt" in our condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025.

The 2027 Notes are the Company’s senior unsecured obligations and rank equally in right of payment with any of the Company’s current and any future senior unsecured indebtedness. The 2027 Notes are effectively subordinated to all of the Company’s future secured indebtedness, if any, to the extent of the value of the related collateral, and the 2027 Notes are structurally subordinated to indebtedness and other liabilities, including trade payables, of the Company’s subsidiaries.

On May 24 and May 25, 2022, in connection with the offering of the 2027 Notes, we entered into convertible note hedge transactions ("2027 Note Hedge Transactions") that cover, subject to customary anti-dilution adjustments, approximately 5.9 million shares of common stock, in the aggregate, at a strike price that initially corresponds to the initial conversion price of the 2027 Notes, subject to adjustment, and are exercisable upon any conversion of the 2027 Notes. Also, on May 24 and May 25, 2022, we entered into privately negotiated warrant transactions ("2027 Warrant Transactions"), whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 6.0 million shares of common stock. As of March 31, 2026, the warrants under the 2027 Warrant Transactions had a weighted average strike price of $105.55 per share, subject to adjustment, and mature beginning September 2027 through April 2028.

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.

The following table reflects the carrying value of our Convertible Notes long-term debt as of March 31, 2026 and December 31, 2025 (in thousands):


	March 31, 2026		December 31, 2025
3.50% Senior Convertible Notes due 2027	$	379,983	$	459,986

Technicolor Patent Acquisition Long-Term Debt

On July 30, 2018, we completed our acquisition of the patent licensing business of Technicolor SA ("Technicolor"), a worldwide technology leader in the media and entertainment sector (the "Technicolor Patent Acquisition"). In conjunction with the Technicolor Patent Acquisition, we assumed Technicolor’s rights and obligations under a joint licensing program with Sony relating to digital televisions and standalone computer display monitors, which commenced in 2015 (the "Madison Arrangement"). An affiliate of CPPIB Credit Investments Inc. ("CPPIB Credit"), a wholly owned subsidiary of Canada Pension Plan Investment Board, is a third-party investor in the Madison Arrangement. CPPIB Credit made certain payments to Technicolor and Sony and agreed to contribute cash to fund certain capital reserve obligations under the arrangement in exchange for a percentage of future revenue, specifically through September 11, 2030 in regard to the Technicolor patents.

Upon our assumption of Technicolor’s rights and obligations under the Madison Arrangement, our relationship with CPPIB Credit meets the criteria in ASC 470-10-25 - Sales of Future Revenues or Various Other Measures of Income ("ASC 470"), which relates to cash received from an investor in exchange for a specified percentage or amount of revenue or other measure of income of a particular product line, business segment, trademark, patent, or contractual right for a defined period. Under this guidance, we recognized the fair value of our contingent obligation to CPPIB Credit, as of the acquisition date, as long-term debt in our condensed consolidated balance sheet. This initial fair value measurement was based on the perspective of a market participant and included significant unobservable inputs which are classified as Level 3 inputs within the fair value hierarchy. The fair value of the long-term debt as of March 31, 2026 and December 31, 2025 is disclosed within Note 3, "Cash, Concentration of Credit Risk and Fair Value of Financial Instruments." Our repayment obligations are contingent upon future royalty revenue generated from the Madison Arrangement and there are no minimum or maximum payments under the arrangement.

Under ASC 470, amounts recorded as debt are amortized under the interest method. At each reporting period, we will review the discounted expected future cash flows over the life of the obligation. The Company made an accounting policy election to utilize the catch-up method when there is a change in the estimated future cash flows, whereby we will adjust the carrying amount of the debt to the present value of the revised estimated future cash flows, discounted at the original effective interest rate, with a corresponding adjustment recognized as interest expense within “Interest Expense” in the condensed consolidated statements of income. The effective interest rate as of the acquisition date was approximately 14.5%. This rate represents the discount rate that equates the estimated future cash flows with the fair value of the debt as of the acquisition date and is used to compute the amount of interest to be recognized each period based on the estimated life of the future revenue streams. During the three months ended March 31, 2026 and 2025, we recognized $0.6 million and $0.3 million, respectively, of interest expense related to this debt. This amount was included within “Interest Expense” in the condensed consolidated statements of income. Any future payments made to CPPIB Credit, or additional proceeds received from CPPIB Credit, will decrease or increase the long-term debt balance accordingly. We made $8.0 million and $1.3 million in payments to CPPIB Credit during the three months ended March 31, 2026 and 2025, respectively.

Technicolor Contingent Consideration

As part of the Technicolor Patent Acquisition, we entered into a revenue-sharing arrangement with Technicolor that created a contingent consideration liability. Under the revenue-sharing arrangement, Technicolor receives 42.5% of future cash receipts from new licensing efforts under the Madison Arrangement only, subject to certain conditions and hurdles. As of March 31, 2026, the contingent consideration liability from the revenue-sharing arrangement was deemed not probable and is therefore not reflected within the condensed consolidated financial statements.

7. INCOME TAXES

In the three months ended March 31, 2026 and 2025, the Company had an estimated effective tax rate of 5.6% and 12.6%, respectively. The change in effective tax rate is due to an increase in the amount of tax benefits related to share-based compensation. During the three months ended March 31, 2026 and 2025, the Company recorded discrete net benefits of $10.4 million and $3.9 million, respectively, primarily related to share-based compensation.

The One Big Beautiful Bill Act (the “OBBBA”) was signed into law on July 4th, 2025. The OBBBA contains significant tax law changes with various effective dates affecting business taxpayers. The tax law changes affecting the Company primarily involve changes to the timing and amount of certain tax deductions, including those related to FDII, GILTI, depreciation, R&D expenditures, and interest expense. This bill did not have a material impact on our financial statements in first quarter 2026.

The effective tax rate reported in any given year will continue to be influenced by a variety of factors, including timing differences between the recognition of book and tax revenue, the level of pre-tax income or loss, the foreign vs. domestic classification of the Company’s customers, and any discrete items that may occur.

During the three months ended March 31, 2026 and 2025, the Company paid approximately $3.1 million and $3.2 million, respectively, in foreign source creditable withholding tax.

8. NET INCOME PER SHARE

Basic Earnings Per Share ("EPS") is calculated by dividing net income or loss available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if options or other securities with features that could result in the issuance of common stock were exercised or converted to common stock or resulting from the unvested outstanding restricted stock units ("RSUs"). The following tables reconcile the numerator and the denominator of the basic and diluted net income per share computation (in thousands, except for per share data):


	Three Months Ended March 31,
	2026		2025
Net income	$	75,329	$	115,602
Weighted-average shares outstanding:
Basic	25,721		25,741
Dilutive effect of stock options and RSUs	1,039		1,275
Dilutive effect of warrants	4,124		2,819
Dilutive effect of convertible securities	4,396		3,670
Diluted	35,280		33,505
Earnings per share:
Basic	$	2.93	$	4.49
Dilutive effect of stock options and RSUs	(0.09)		(0.17)
Dilutive effect of warrants	(0.34)		(0.38)
Dilutive effect of convertible securities	(0.36)		(0.49)
Diluted	$	2.14	$	3.45

Shares of common stock issuable upon the exercise or conversion of certain securities have been excluded from our computation of EPS because the strike price or conversion rate, as applicable, of such securities was greater than the average market price of our common stock and, as a result, the effect of such exercise or conversion would have been anti-dilutive. Set forth below are the securities and the weighted average number of shares of common stock underlying such securities that were excluded from our computation of EPS for the periods presented (in thousands):


	Three Months Ended March 31,

Warrants	1,858	3,136

Table of Contents

Convertible Notes and Warrants

Refer to Note 5, "Obligations," for information about the Company's convertible notes and warrants and related conversion and strike prices. During periods in which the average market price of the Company's common stock is above the applicable conversion price of the Company's convertible notes, or above the strike price of the Company's outstanding warrants, the impact of conversion or exercise, as applicable, would be dilutive and such dilutive effect is reflected in diluted EPS. As a result, in periods where the average market price of the Company's common stock is above the conversion price or strike price, as applicable, under the if-converted method, the Company calculates the number of shares issuable under the terms of the convertible notes and the warrants based on the average market price of the stock during the period, and includes that number in the total diluted shares outstanding for the period.

9. SEGMENT PERFORMANCE MEASURES AND EXPENSES

Our Chief Executive Officer, who is our chief operating decision maker (“CODM”), assesses company-wide performance and allocates resources based on consolidated financial information. Consequently, we view the entire organization as one reportable segment and the strategic purpose of all operating activities is to support that one segment. Our CODM evaluates company-wide performance based on multiple performance measures, including, but not limited to, net income. Our CODM does not generally evaluate our performance using asset or historical cash flow information.

The table below provides the calculation of net income, which is the performance measure that is most consistent with GAAP, and the significant operating expenses included in this performance measure (in thousands):


	Three months ended March 31,
	2026		2025

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

OVERVIEW

The following discussion should be read in conjunction with the unaudited, condensed consolidated financial statements and notes thereto contained in Part I, Item 1 of this Quarterly Report on Form 10-Q, in addition to our 2025 Form 10-K, other reports filed with the SEC and the Statement Pursuant to the Private Securities Litigation Reform Act of 1995 — Forward-Looking Statements below.

Throughout the following discussion and elsewhere in this Quarterly Report on Form 10-Q, we refer to “catch-up revenue.” For variable and dynamic fixed-fee license agreements, “catch-up revenue” primarily represents revenue associated with reporting periods prior to the execution of the license agreement.

New Agreements

During first quarter 2026, we entered into six patent license agreements, including agreements with Xiaomi, LG Electronics, Sony, Buffalo Americas, Inc., and Metz.

The agreement with Xiaomi has a term of five years and covers Xiaomi's cellular products, including its smartphones and other cellular-enabled devices, under InterDigital's standard essential cellular, WiFi, and HEVC patents.

The agreement with LG Electronics (the "LG TV agreement") licenses LG’s digital TVs and computer display monitors under InterDigital´s joint licensing program with Sony and includes licenses to technologies including ATSC 3.0, Wi-Fi and video codecs.

The agreement with Sony covers all of Sony’s end user devices under InterDigital's global patent portfolio, including InterDigital's standard essential cellular, Wi-Fi, and video patents.

Injunction Awards

During first quarter 2026, we were awarded injunctions in our intellectual property enforcement actions against Disney and Transsion. In Germany, the Munich Regional Court granted an injunction relating to Disney’s infringement of an InterDigital patent related to HEVC compression technology, representing the fifth injunction we have obtained in proceedings involving Disney. In Brazil, the Third Regional Business Court of Rio de Janeiro granted a preliminary injunction relating to Transsion’s infringement of two InterDigital 5G patents and found that our licensing offer was fair, reasonable, and non-discriminatory (FRAND).

For more information on these proceedings, see Note 6, “Litigation and Legal Proceedings,” to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Notes, Hedge, and Warrant Transactions

During first quarter 2026, the 2027 Notes had a dilutive impact of 4.4 million shares, which are offset from an economic standpoint by the 2027 Note Hedge Transactions and would result in no incremental outstanding shares after conversion. However, under Generally Accepted Accounting Principles in the United States ("GAAP"), we are required to exclude the impact of the shares received from the 2027 Note Hedge Transactions counterparties from the calculation of weighted-average diluted shares outstanding.

During the period from January 1, 2024 through June 30, 2026, holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes. 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. Refer to "Financial Position, Liquidity, and Capital Resources — Convertible Notes" for further information regarding how changes in our stock price would affect the number of shares issuable related to the 2027 Warrant Transactions. For example, if the share price were $350, we would issue 4.2 million shares of common stock related to the 2027 Warrant Transactions.

Return of Capital

In March 2026, we announced a regular quarterly cash dividend of $0.70 per share, which is a 17% increase compared to the dividend declared in first quarter 2025. During first quarter 2026, we returned $26.3 million to shareholders, including $18.1 million, or $0.70 per share, of cash dividends declared and $8.2 million through the repurchase of shares of common stock. We also reduced our debt by $88.0 million, including the $80.0 million principle payment on the conversion of the 2027 Notes.

As of April 30, 2026, there was $108.0 million remaining under the share repurchase authorization, which we plan to utilize to periodically repurchase additional common shares. See Part II, Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds—Issuer Purchases of Equity Securities of this Quarterly Report on Form 10-Q.

Cash & Short-term Investments

As of March 31, 2026, we had $1.1 billion of cash, restricted cash, and short-term investments and approximately $1.7 billion of cash payments due under contracted fixed price agreements, which includes our conservative estimates of the minimum cash receipts that we expect to receive under the Lenovo arbitration.

94% of our first quarter 2026 revenue came from fixed-fee agreements. Such agreements often have prescribed payment schedules that are uneven and sometimes front-loaded, resulting in timing differences between when we collect the cash payments and recognize the related revenue.

The following table reconciles the timing differences between cash receipts and recognized revenue during the three months ended March 31, 2026 and 2025, including the resulting operating cash flow (in thousands):


	Three Months Ended March 31,
Cash vs. Non-cash revenue:	2026		2025
Fixed fee cash receipts (a)	$	134,830	$	22,579
Other cash receipts (b)	7,044		24,251
Change in deferred revenue	(85,861)		38,750
Change in receivables	138,511		115,966
Other	10,892		8,961
Total Revenue	$	205,416	$	210,507
Net cash provided by (used in) operating activities	$	16,081	$	(19,989)

(a) Fixed fee cash receipts are comprised of cash receipts from Dynamic Fixed-Fee Agreement royalties, including the associated catch-up revenue.

(b) Other cash receipts are primarily comprised of cash receipts related to our variable patent royalty revenue and catch-up revenue.

When we collect payments on a front-loaded basis, we recognize a deferred revenue liability equal to the cash received and accounts receivable recorded which relate to revenue expected to be recognized in future periods. That liability is then reduced as we recognize revenue over the balance of the agreement. The following table shows the projected amortization of our current and long-term deferred revenue as of March 31, 2026 (in thousands):


	Deferred Revenue
Remainder of 2026	$	204,073

Revenue

First quarter 2026 revenue of $205.4 million includes $63.6 million of catch-up revenue, while first quarter 2025 revenue of $210.5 million includes $84.8 million of catch-up revenue. The $5.1 million decrease in total revenue was driven by lower catch-up revenue, partially offset by recurring revenue recognized from thirteen patent license agreements signed since first quarter 2025. In first quarter 2026, revenue (in descending order) from LG, Apple, and Samsung each comprised 10% or more of our consolidated revenue. Refer to "Results of Operations — First Quarter 2026 Compared to First Quarter 2025" for further discussion of our 2026 revenue.

Impact of Macroeconomic and Geopolitical Factors

We have been actively monitoring the impact of the current macroeconomic environment in the U.S. and globally characterized by market volatility, inflation, supply chain issues, high interest rates, tariffs and other potential trade-related sanctions, and the potential for a recession. These market factors, as well as the impacts of global conflicts, have not had a material impact on our business to date. However, if these conditions continue or worsen, they could have an adverse effect on our operating results and our financial condition.

Comparability of Financial Results

When comparing first quarter 2026 financial results against other periods, the following items should be taken into consideration:

Revenue

•Our first quarter 2026 revenue includes $63.6 million of catch-up revenue primarily related to the new patent license agreements with LG and Sony signed in first quarter 2026.

Operating Expenses

•During first quarter 2026, we incurred $26.3 million of nonrecurring revenue share costs associated with the catch-up revenue recognized in the period.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our significant accounting policies are described in Note 2, "Summary of Significant Accounting Policies and New Accounting Guidance", in the notes to condensed consolidated financial statements included in our 2025 Form 10-K. A discussion of our critical accounting policies, and the estimates related to them, are included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2025 Form 10-K. There have been no material changes to our existing critical accounting policies from the disclosures included in our 2025 Form 10-K. Refer to Note 1, “Basis of Presentation,” in the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for updates related to new accounting pronouncements and changes in accounting policies.

FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of liquidity are cash, cash equivalents, and short-term investments, as well as cash generated from operations. We believe we have the ability to obtain additional liquidity through debt and equity financings. From time to time, we may engage in a variety of transactions to augment our liquidity position as our business dictates and to take advantage of favorable interest rate environments or other market conditions, including the incurrence or issuance of debt and the refinancing or restructuring of existing debt. Based on our past performance and current expectations, we believe our available sources of funds, including cash, cash equivalents, short-term investments, and cash generated from our operations, will be sufficient to finance our operations, capital requirements, debt obligations, existing stock repurchase program, dividend program, and other contractual obligations discussed below in both the short-term over the next twelve months, and the long-term beyond twelve months.

Cash, cash equivalents, restricted cash, and short-term investments

As of March 31, 2026 and December 31, 2025, we had the following amounts of cash and cash equivalents, restricted cash, and short-term investments (in thousands):


	March 31, 2026		December 31, 2025		Increase / (Decrease)
Cash and cash equivalents	$	607,599	$	738,960	$	(131,361)
Restricted cash included within prepaid and other current assets	9,991		15,308		(5,317)

Short-term investments	474,260		504,200		(29,940)
Total cash, cash equivalents, restricted cash, and short-term investments	$	1,091,850	$	1,258,468	$	(166,618)

Table of Contents

The net decrease in cash, cash equivalents, restricted cash, and short-term investments was attributable to cash used in financing activities of $169.2 million and cash used in investing activities of $13.4 million, excluding sales and purchases of short-term investments, partially offset by cash provided by operating activities of $16.1 million. Refer to the sections below for further discussion of these items.

Cash flows provided by (used in) operating activities

Cash flows provided by (used in) operating activities in the first quarter 2026 and 2025 (in thousands) were as follows:


	Three Months Ended March 31,
	2026		2025		Change
Net cash provided by (used in) operating activities	$	16,081	$	(19,989)	$	36,070

Our cash flows provided by (used in) operating activities are principally derived from cash receipts from patent license agreements, offset by cash operating expenses and income tax payments. The $36.1 million change in cash provided by (used in) operating activities was primarily driven by higher cash receipts due to the timing of receipts under new and existing agreements and was partially offset by higher cash operating expenses, including increased revenue share and intellectual property enforcement costs. The table below sets forth the significant items comprising our cash flows provided by (used in) operating activities during the three months ended March 31, 2026 and 2025 (in thousands):


	Three Months Ended March 31,
	2026		2025		Change
Total Cash Receipts	$	141,874	$	46,830	$	95,044




Cash Outflows:
Cash operating expenses a	(93,608)		(50,964)		(42,644)
Income taxes paid b	(6,462)		(10,204)		3,742
Total cash outflows	(100,070)		(61,168)		(38,902)

Other working capital adjustments	(25,723)		(5,651)		(20,072)

Cash flows provided by (used in) operating activities	$	16,081	$	(19,989)	$	36,070

______________________________

(a) Cash operating expenses include operating expenses less depreciation and disposals of fixed assets, amortization of patents, and non-cash compensation. Amount includes revenue share costs of $27.5 million and $2.6 million in first quarter 2026 and 2025, respectively.

(b) Income taxes paid include foreign withholding taxes.

Cash flows from investing and financing activities

Net cash provided by investing activities for first quarter 2026 was $16.4 million, a $43.1 million change from $59.5 million in first quarter 2025. During first quarter 2026, we sold $29.8 million of short-term marketable securities, net of purchases, and capitalized $15.1 million of patent costs and property and equipment purchases. During first quarter 2025, we sold $86.2 million of short-term marketable securities, net of purchases, and capitalized $26.7 million of patent costs and property and equipment purchases.

Net cash used in financing activities for first quarter 2026 was $169.2 million, a change of $126.2 million from $43.0 million in first quarter 2025. This change was primarily attributable to an $80.0 million payment related to the partial conversion of the 2027 Notes in first quarter 2026. The change also reflects higher cash outflows in 2026, including a $22.8 million increase in taxes withheld on restricted stock unit vestings due to a higher share price at vesting and a $6.4 million increase in dividends paid following the increases in the declared dividend from $0.45 to $0.70. In addition, during first quarter 2025, we received $7.3 million due to the exercise of stock options.

Other

Our combined short-term and long-term deferred revenue balance as of March 31, 2026 was approximately $420.5 million, a net increase of $90.9 million from December 31, 2025. This increase in deferred revenue was primarily due to cash receipts on new and existing patent license agreements, partially offset by amortization of deferred revenue recognized in the period.

Based on current license agreements, we expect the amortization of dynamic fixed-fee royalty payments to reduce the March 31, 2026 deferred revenue balance of $420.5 million by $261.1 million over the next twelve months.

Convertible Notes

See Note 5, “Obligations” to the Notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for definitions of capitalized terms below.

From January 1, 2024 through June 30, 2026, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes.

Our 2027 Notes are included in the diluted earnings per share ("diluted EPS") calculation using the if-converted method in accordance with GAAP. Under the if-converted method, we assume that conversion of convertible securities occurs at the beginning of the reporting period. The 2027 Notes are convertible into cash up to the aggregate principal amount of the 2027 Notes to be converted and any value in excess of the principal amount ("the conversion spread") may be settled in cash, shares of the Company’s common stock, or a combination thereof. As the principal amount is required to be paid in cash and only the conversion spread may result in shares being issued, we only include the net number of incremental shares that would be issued upon conversion. We calculate the number of shares of our common stock issuable under the terms of the 2027 Notes based on the average market price of our common stock during the applicable reporting period and include that number in the weighted‑average diluted shares outstanding for the period.

At the time we issued the 2027 Notes, we entered into the 2027 Call Spread Transactions that together were designed to have the economic effect of reducing potential dilution upon conversion of the 2027 Notes by, in effect, increasing the conversion price of the 2027 Notes on an economic basis. However, under GAAP, since the impact of the 2027 Note Hedge Transactions is anti-dilutive, we exclude from the calculation of diluted EPS the shares of our common stock that we would receive from the counterparties upon settlement of the 2027 Note Hedge Transactions.

During periods in which the average market price of our common stock is above the applicable conversion price of the 2027 Notes (initial conversion price of approximately $77.49 per share), or above the strike price of the warrants (weighted average strike price of $105.55 per share), the impact of conversion of the 2027 Notes or exercise of the warrants, as applicable, would be dilutive and such dilutive effect is reflected in diluted earnings per share. In those periods, we calculate the incremental shares associated with the 2027 Notes (under the if‑converted method) or the warrants based on the average market price of our common stock during the period and include those incremental shares in weighted‑average diluted shares outstanding.

Under the if-converted method, changes in the price per share of our common stock can have a significant impact on the number of shares that we must include in the diluted EPS calculation. As described in Note 5, "Obligations" in the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, the 2027 Notes are convertible into cash up to the aggregate principal amount of 2027 Notes to be converted and any remaining obligations may be settled in cash, shares of the Company’s common stock or a combination thereof ("net share settlement"). Assuming net share settlement upon conversion, the following table illustrates how changes in our stock price would affect the shares issuable under the 2027 Notes and related warrant transactions, the incremental shares included in diluted EPS under the if‑converted method (“Total Incremental Shares”), the shares deliverable to us under the 2027 Note Hedge Transactions, and the resulting net incremental shares, based on $380.0 million aggregate principal amount outstanding and approximately 6.0 million related warrants as of March 31, 2026 (in thousands):

RESULTS OF OPERATIONS

First Quarter 2026 Compared to First Quarter 2025

Revenue

The following table compares first quarter 2026 revenue to first quarter 2025 revenue (in thousands):


	Three Months Ended March 31,
	2026		2025		Increase/(Decrease)

Smartphone	$	123,391	$	183,991	$	(60,600)	(33)	%
CE, IoT/Auto	81,891		26,267		55,624		212	%
Other	134		249		(115)		(46)	%
Total Revenue	$	205,416	$	210,507	$	(5,091)	(2)	%

Catch-up revenue(a), included above	$	63,623	$	84,785	$	(21,162)	(25)	%

(a) Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.

Total revenue of $205.4 million was relatively flat compared to first quarter 2025, decreasing slightly primarily due to lower catch-up revenue recognized from the LG TV and Sony agreements in first quarter 2026, as compared to catch-up revenue from vivo Mobile in first quarter 2025, and the expiration of the Samsung TV agreement. This decrease was partially offset by new revenue from the Samsung arbitration decision and from thirteen new patent license agreements signed in the last twelve months.

In first quarter 2026 and 2025, 61% and 71%, respectively, of our total revenue was attributable to licensees that individually accounted for 10% or more of our total revenue. In first quarter 2026 and 2025, the following licensees accounted for 10% or more of our total revenue:


	Three Months Ended March 31,
	2026	2025
Customer A	29%	<10%
Customer B	16%	16%
Customer C	16%	12%
Customer D	<10%	43%

Operating Expenses

The following table summarizes the changes in operating expenses between first quarter 2026 and first quarter 2025 by category (in thousands):


	Three Months Ended March 31,
	2026		2025		Increase/(Decrease)
Research and portfolio development	$	55,835	$	47,430	$	8,405	18	%
Licensing	52,119		17,677		34,442		195	%
General and administrative	15,201		13,568		1,633		12	%

Total operating expenses	$	123,155	$	78,675	$	44,480	57	%

Table of Contents

Operating expenses increased to $123.2 million in first quarter 2026 compared to $78.7 million in first quarter 2025. The $44.5 million increase in total operating expenses was primarily due to changes in the following items (in thousands):


	Increase/(Decrease)
Revenue share	$	24,849
Intellectual property enforcement, net	10,527
Personnel-related costs	4,284
Other	4,820
Total increase in operating expenses	$	44,480

The $44.5 million increase in operating expenses was driven by a $24.8 million increase in revenue share costs, primarily related to the catch-up revenue recognized on the LG TV agreement signed in first quarter 2026, and a $10.5 million increase in intellectual property enforcement costs related to the Disney, Amazon, and Transsion proceedings. These enforcement costs are expected to continue through 2026 and could increase as these and other matters progress. In addition, personnel-related costs increased $4.3 million primarily due to higher wages and employer-paid payroll taxes.

Research and portfolio development expense: Research and portfolio development expense increased compared to first quarter 2025 primarily due to the above noted increase in personnel-related costs.

Licensing expense: Licensing expense increased compared to first quarter 2025 primarily due to the above noted changes in revenue share and intellectual property enforcement costs.

General and administrative expense: General and administrative expense increased compared to first quarter 2025 primarily due to the above noted increase in personnel-related costs.

Non-Operating Income (expense), net

The following table compares first quarter 2026 non-operating expense, net to first quarter 2025 non-operating income, net (in thousands):


	Three Months Ended March 31,
	2026		2025		Increase/(Decrease)
Interest expense	$	(9,067)	$	(9,871)	$	804	8	%
Interest and investment income	10,529		9,264		1,265		14	%


Other (expense) income, net	(3,929)		994		(4,923)		(495)	%
Total non-operating (expense) income, net	$	(2,467)	$	387	$	(2,854)	(737)	%

The change in non-operating (expense) income, net was primarily due to a foreign currency translation net loss arising from translation of our foreign subsidiaries of $2.9 million in first quarter 2026, compared to a $2.2 million net gain in first quarter 2025.

Income taxes

In first quarter 2026 and 2025, based on the statutory federal tax rate net of discrete federal and state taxes, we had an effective tax rate of 5.6% and 12.6%, respectively. The change in effective tax rate was primarily due to an increase in the amount of tax benefits related to share-based compensation.

Plan:			The Company’s 2025 Equity Incentive Plan, as amended

Name of Participant:			%%FIRST_NAME%-% %%LAST_NAME%-%

Grant Number:			%%OPTION_NUMBER%-%

Grant Date:			%%OPTION_DATE,’Month DD, YYYY’%-%

Expiration Date:			The 10th anniversary of the Grant Date

Target Shares Granted:			%%TOTAL_SHARES_GRANTED,’999,999,999’%-%
			(“Target Options”);
			The maximum number of Shares issuable under this Award is 200% of the Target Options (“Maximum Options”), as described above.

Type of Option:			%%OPTION_TYPE_LONG%-%

Exercise Price:			%%OPTION_PRICE%-%

Vesting Schedule:			The Option vests upon “Vesting Date” as follows:

			On [VEST DATE], if at all, subject to Participant continuing to be a Service Provider through such date and the achievement, as approved by the Human Capital Committee of the Board, of the performance goal(s), as set forth in Exhibit A, and parameters set forth in the Terms and Conditions (the date on which all or a portion of the Option vests, the “Vesting Date”); provided, that the Option may vest earlier pursuant to the terms of this Term Sheet and the Terms and Conditions.
			Notwithstanding anything herein to the contrary, in no event shall more than the Maximum Options vest and be eligible for exercise.


Pro-rated Vesting:			If Participant’s employment is terminated by the Company or any Parent, Subsidiary, or Affiliate of the Company (as applicable, the “Employer”) without Cause or by reason of Participant’s death or Disability, in each case, during the last year of a Performance Period, the Option will remain eligible to vest as to a prorated portion, subject to Participant’s execution of a release of claims in favor of the Company within 60 days following termination of employment, except that no release is required for a termination of Participant’s employment due to death or Disability. Such pro-rata portion will be determined by multiplying the number of Shares subject to the Option that would otherwise have become vested according to the performance goals and parameters set forth in the Terms and Conditions and Exhibit A (based on actual performance over the performance period), if any, by the fraction equal to the number of days during the Performance Period that Participant was employed by the Employer divided by the total number of days during the Performance Period.
			Notwithstanding the Termination Period section below, on a qualifying termination described in this section, the Option will remain exercisable for 6 months after the Vesting Date for such Performance Period. For clarity, on a qualifying termination described in this section, any Shares subject to the unvested Option will not immediately revert to the Plan on such termination. Instead such unvested Option will remain eligible to vest on the Vesting Date of such Performance Period and any vested Option will remain exercisable for 6 months after the Vesting Date.

Change in Control; Accelerated Vesting:
			Upon a Change in Control, the Option (to the extent then outstanding) will be deemed earned based on the greater of target or actual performance, measured as of the day immediately prior to the Change in Control; such deemed earned Award shall remain subject to service-based vesting as described under “Vesting Schedule” above (without regard to any further performance-based conditions on Exhibit A or otherwise). For the avoidance of doubt, any reference in Section 16(c) of the Plan to vesting criteria being deemed achieved at one hundred percent (100%) of target levels shall instead refer to being deemed achieved based on the greater of target or actual performance, measured as of the day immediately prior to the Change in Control. Without limiting the generality of the foregoing, if Participant’s employment is terminated within 1 year following a Change in Control, either by the Employer other than for Cause, death, or Disability or by Participant for Good Reason, 100% of the earned but then-unvested portion of the Award will vest upon termination, subject to Participant’s execution of a release of claims in favor of the Company within 60 days following termination of employment.



Termination Period:			This Option will be exercisable for 6 months after Participant ceases to be a Service Provider for any reason other than termination of Participant’s Service Provider status for Cause, unless such termination is due to Participant’s death or Disability, in which case this Option will be exercisable for 12 months after Participant ceases to be a Service Provider; provided, however, that if Participant dies during such 6-month post-termination exercise period, the Option may be exercised following Participant’s death for 12 months after Participant’s death. If Participant’s Service Provider status is terminated by the Company for Cause, the entire Option, whether or not then vested and exercisable, will be immediately forfeited and canceled as of the date of such termination. Notwithstanding the foregoing sentence, in no event may this Option be exercised after the Expiration Date listed above and may be subject to earlier termination as provided in Section 16(c) of the Plan.



Accelerated Vesting:			If Participant’s employment is terminated within 1 year following a Change in Control, either by the Employer other than for Cause, death, or Disability or by Participant for Good Reason, 100% of the then-unvested portion of the Award will vest upon termination, subject to Participant’s execution of a release of claims in favor of the Company within 60 days following termination of employment.


Change in Control; Accelerated Vesting:
			Upon a Change in Control, the Award (to the extent then outstanding) will be deemed earned based on the greater of target or actual performance, measured as of the day immediately prior to the Change in Control; such deemed earned Award shall remain subject to service-based vesting as described under “Vesting Schedule” above (without regard to any further performance-based conditions on Exhibit A or otherwise). For the avoidance of doubt, any reference in Section 16(c) of the Plan to vesting criteria being deemed achieved at one hundred percent (100%) of target levels shall instead refer to being deemed achieved based on the greater of target or actual performance, measured as of the day immediately prior to the Change in Control. Without limiting the generality of the foregoing, if Participant’s employment is terminated within 1 year following a Change in Control, either by the Employer other than for Cause, death, or Disability or by Participant for Good Reason, 100% of the then-unvested portion of the Award will vest upon termination, subject to Participant’s execution of a release of claims in favor of the Company within 60 days following termination of employment.
