    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
    March 31, 2024
    (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, 2024, the results of our operations for the three months ended March 31, 2024 and 2023 and our cash flows for the three months ended March 31, 2024 and 2023. 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, 2023 (our “2023 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 15, 2024. Definitions of capitalized terms not defined herein appear within our 2023 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 revenues 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 2023 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.
    Supplemental Cash Flow Information
    The following table presents additional supplemental cash flow information for the three months ended March 31, 2024 and 2023 (in thousands):

    New Accounting Guidance
    Accounting Standards Update: Improvements to Reportable Segment Disclosures
    In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”. The amendments in the ASU require disclosures to include significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption allowed. We are currently evaluating the impact of adoption on our financial disclosures.

    Accounting Standards Update: Improvements to Income Tax Disclosures
    In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments in the ASU enhance income tax disclosures, primarily through standardization, disaggregation of rate reconciliation categories, and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption allowed. We are currently evaluating the impact of adoption on our financial disclosures.

The following table provides a reconciliation of total cash, cash equivalents and restricted cash as of March 31, 2024, December 31, 2023 and March 31, 2023 to the captions within the condensed consolidated balance sheets and condensed consolidated statements of cash flows (in thousands):

    Total cash, cash equivalents and restricted cash$461,190 $442,961 $442,710 
    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. Four licensees comprised 85% and 84% of our accounts receivable balance, as of March 31, 2024 and December 31, 2023, respectively. We perform ongoing credit evaluations of our licensees, who generally include large, multinational, wireless telecommunications 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.
    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.

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 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 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 Notes (which is equivalent to an initial conversion price of approximately $77.49 per share). From the period January 1, 2024 through June 30, 2024, 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 are included in "Current portion of long-term debt" in our condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023.
    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, including its 2.00% Senior Convertible Notes due 2024 (the “2024 Notes” and together with the 2027 Notes, the "Convertible Notes"). 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 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, whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 5.9 million shares of common stock. As of March 31, 2024, the warrants under the 2027 Warrant Transactions had a weighted average strike price of $106.31 per share, subject to adjustment.
    2024 Notes, and Related Note Hedge and Warrant Transactions
    On June 3, 2019, we issued $400.0 million in aggregate principal amount of 2024 Notes. The net proceeds from the issuance of the 2024 Notes, after deducting the initial purchasers' transaction fees and offering expenses, were approximately $391.6 million. The 2024 Notes bear interest at a rate of 2.00% per year, payable in cash on June 1 and December 1 of each year, commencing on December 1, 2019, and mature on June 1, 2024, unless earlier redeemed, converted or repurchased.
    Commencing on March 1, 2024, the 2024 Notes became convertible at any time prior to 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date of the 2024 Notes. The 2024 Notes are convertible into cash and shares of our common stock, with a specified dollar amount of $1,000 per $1,000 principal amount of 2024 Notes and any remaining amounts in shares of our common stock, at an initial conversion rate of 12.3018 shares of our common stock per $1,000 principal amount of 2024 Notes (which is equivalent to an initial conversion price of approximately $81.29 per share).
    The 2024 Notes are senior unsecured obligations of the Company and rank equally in right of payment with any of our current and any future senior unsecured indebtedness. The 2024 Notes are effectively subordinated to all of our future secured indebtedness, if any, to the extent of the value of the related collateral, and the 2024 Notes are structurally subordinated to indebtedness and other liabilities, including trade payables, of our subsidiaries.
    On May 29 and May 31, 2019, in connection with the offering of the 2024 Notes, we entered into convertible note hedge transactions (collectively, the "2024 Note Hedge Transactions") that cover, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock, in the aggregate, at a strike price that initially corresponds to the initial conversion price of the 2024 Notes, subject to adjustment, and are exercisable upon any conversion of the 2024 Notes. On May 29 and May 31, 2019, we also entered into privately negotiated warrant transactions (collectively, the "2024 Warrant Transactions" and, together with the 2024 Note Hedge Transactions, the "2024 Call Spread Transactions"), whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock at an initial strike price of approximately $109.43 per share, subject to adjustment.

    During second quarter 2022, we repurchased $273.8 million in aggregate principal amount of the 2024 Notes in privately negotiated transactions concurrently with the offering of the 2027 Notes. As a result of the partial repurchase of the 2024 Notes, $126.2 million in aggregate principal amount of the 2024 Notes remained outstanding as of March 31, 2024. Additionally, in connection with the partial repurchase of the 2024 Notes, the Company entered into partial unwind agreements that amend the terms of the 2024 Note Hedge Transactions to reduce the number of options corresponding to the principal amount of the repurchased 2024 Notes. The unwind agreements also reduce the number of warrants exercisable under the 2024 Warrant Transactions. As a result of the partial unwind transactions, approximately 1.6 million shares of common stock in the aggregate were covered under each of the 2024 Note Hedge Transactions and the 2024 Warrant Transactions as of March 31, 2024. As of March 31, 2024, the warrants under the 2024 Warrant Transactions had a strike price of approximately $109.43 per share, as adjusted.

    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 and is referred to as 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 has made certain payments to Technicolor and Sony and has agreed to contribute cash to fund certain capital reserve obligations under the arrangement in exchange for a percentage of future revenues, 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, 2024 and December 31, 2023 is disclosed within Note 3, "Cash, Concentration of Credit Risk and Fair Value of Financial Instruments." Our repayment obligations are contingent upon future royalty revenues generated from the Madison Arrangement and there are no minimum or maximum payments under the arrangement.
    14

    Table of Contents
    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, 2024 and 2023, we recognized $0.6 million and $0.3 million of interest expense related to this debt. This 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 a $1.6 million payment to CPPIB Credit during the three months ended March 31, 2024.
    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 from the Madison Arrangement only, subject to certain conditions and hurdles. As of March 31, 2024, the contingent consideration liability from the revenue-sharing arrangement was deemed not probable and is therefore not reflected within the consolidated financial statements.
    6. LITIGATION AND LEGAL PROCEEDINGS
    ARBITRATIONS AND COURT PROCEEDINGS
    Lenovo
    UK Proceedings
    On August 27, 2019, the Company and certain of its subsidiaries filed a claim in the UK High Court against Lenovo Group Limited and certain of its subsidiaries. The claim, as amended, alleges infringement of five of the Company’s patents relating to 3G and/or 4G/LTE standards: European Patent (UK) Nos. 2,363,008; 2,421,318; 2,485,558; 2,557,714; and 3,355,537. The Company sought, among other relief, injunctive relief to prevent further infringement of the asserted patents or, in the alternative, a determination of the terms of a FRAND license.
    On July 29, 2021, the UK High Court issued its decision regarding the first technical trial finding European Patent (UK) No. 2,485,558 valid, infringed, and essential to Release 8 of LTE. Lenovo appealed this decision, and on January 19, 2023, the UK Court of Appeal upheld the UK High Court’s findings that Lenovo is infringing on InterDigital’s valid and essential patent. On January 6, 2022, the UK High Court issued its decision regarding the second technical trial finding European Patent (UK) No. 3,355,537 invalid, but essential and infringed but for the finding of invalidity. The Company appealed this decision as legally erroneous, and on February 9, 2023, the UK Court of Appeal allowed the appeal, finding that Lenovo is infringing on InterDigital’s valid and essential patent. On January 31, 2023, the UK High Court issued its decision regarding the third technical trial finding European Patent (UK) No. 2,421,318 valid, essential, and infringed. On March 7, 2023, the UK High Court issued an order staying all deadlines with respect to the fourth and fifth technical trials. On March 16, 2023, the UK High Court issued its order regarding judgment in the trial to determine how much Lenovo must pay for a license to the Company’s portfolio of cellular assets, awarding the Company a lump sum of $138.7 million for such license through December 31, 2023. On June 27, 2023, the court issued an order awarding the Company an additional $46.2 million, thus increasing the total award to $184.9 million, which was paid on July 11, 2023. The court also found that the Company should pay a portion of Lenovo’s costs and granted both parties permission to appeal on certain grounds. Both parties filed Appellant’s Notices and the appeals were docketed on July 31, 2023. On September 19, 2023, the Court of Appeal granted the Company permission to appeal on all its requested grounds. The appeal is scheduled to be heard on June 10, 2024.

    On September 24, 2023, Lenovo filed a new claim in the UK High Court against the Company. The claim alleges invalidity of two of the Company’s patents relating to 4G/LTE standards: European Patent (UK) Nos. 2,557,714 and 2,557,715. Lenovo sought, among other relief, a declaration that the patents at issue are invalid, not essential, and not infringed, revocation of the patents at issue, and a declaration that, upon expiration of the current license in 2023, Lenovo is licensed under terms to be determined by the UK High Court through 2028 or, in the alternative, a determination of the terms of a FRAND license. On October 19, 2023, Lenovo filed a request for an order that the Company indicate whether it is prepared to give an unconditional undertaking to enter into a global license on terms set by the UK Court, or failing that, a declaration that the Defendants are unwilling licensors; a hearing was held on December 12, 2023 where Lenovo agreed to stay its application. On November 22, 2023, the Company filed a jurisdiction challenge. A hearing on the jurisdiction challenge took place on April 24-25, 2024, and on April 25, 2024 the jurisdiction challenge was denied. On November 28, 2023, Lenovo filed an application seeking an expedited FRAND trial and an interim license until a FRAND decision is issued in the UK. A hearing on the interim license was held on February 26-27, 2024; on March 21, 2024 the UK High Court denied Lenovo’s request for the interim license. A hearing on Lenovo’s request for an expedited FRAND trial will be scheduled now that the interim license and jurisdiction challenge issues are resolved.
    District of Delaware Patent Proceedings
    On August 28, 2019, the Company and certain of its subsidiaries filed a complaint in the United States District Court for the District of Delaware (the "Delaware District Court") against Lenovo Holding Company, Inc. and certain of its subsidiaries alleging that Lenovo infringes eight of the Company’s U.S. patents-U.S. Patent Nos. 8,085,665; 8,199,726; 8,427,954; 8,619,747; 8,675,612; 8,797,873; 9,203,580; and 9,456,449-by making, using, offering for sale, and/or selling Lenovo wireless devices with 3G and/or 4G LTE capabilities.

    District of Delaware Antitrust Proceedings
    On April 9, 2020, Lenovo (United States) Inc. and Motorola Mobility LLC filed a complaint in the Delaware District Court against the Company and certain of its subsidiaries. The complaint alleges that the Company defendants have violated Sections 1 and 2 of the Sherman Act in connection with, among other things, their licensing of 3G and 4G standards essential patents ("SEPs"). The complaint further alleges that the Company defendants have violated their commitment to the ETSI with respect to the licensing of 3G and 4G SEPs on FRAND terms and conditions. The complaint seeks, among other things (i) rulings that the Company defendants have violated Sections 1 and 2 of the Sherman Act and are liable for breach of their ETSI FRAND commitments, (ii) a judgment that the plaintiffs are entitled to a license with respect to the Company’s 3G and 4G SEPs on FRAND terms and conditions, and (iii) injunctions against any demand for allegedly excessive royalties or enforcement of the Company defendants’ 3G and 4G U.S. SEPs against the plaintiffs or their customers via patent infringement proceedings.

The Delaware District Court dismissed the Sherman Act Section 1 claim without prejudice, denied the motion to dismiss the Sherman Act Section 2 claim, and consolidated the Section 2 and breach of contract claims with Company’s Delaware patent proceeding discussed above. Accordingly, these claims have been stayed pending resolution of all appeals in the UK proceedings.

On May 20, 2022, the Company filed an application challenging, among other things, process of service and the jurisdiction of the Guangzhou IP Court. On January 12, 2023, the Guangzhou IP Court denied the application. On February 28, 2023, the Company filed an appeal to the decision. The Supreme People’s Court denied the appeal on September 7, 2023. An initial evidentiary hearing was held on October 13, 2023.
    Spain Proceedings
    On March 1, 2022, a subsidiary of the Company filed patent infringement claims in the Barcelona Commercial Courts against Oppo and certain of its affiliates, OnePlus and certain of its affiliates, and realme and certain of its affiliates. The Company filed its amended complaint on April 25, 2022, alleging infringement of European Patent Nos. 3,355,537; 2,485,558; 2,421,318; and 2,557,715 relating to cellular 3G, 4G/LTE and/or 5G standards. The Company is seeking, among other relief, injunctive relief to prevent further infringement of the asserted patents. Oppo filed its reply, invalidity counterclaims, and defenses on July 31. 2023. The Company filed its response to Oppo’s counterclaims on December 20, 2023.
    Samsung
    The Company reached an agreement with Samsung Electronics Co. Ltd. (“Samsung”) to enter into binding arbitration to determine the final terms of a renewed patent license agreement to certain of the Company’s patents, which will be effective from January 1, 2023. The Company and Samsung have also agreed not to initiate certain claims against the other during the arbitration. On March 31, 2023, the Company filed a request for arbitration with the International Chamber of Commerce.
    On July 21, 2023, the International Chamber of Commerce confirmed the full tribunal for the arbitration. The hearing has been scheduled for Summer of 2024 with an expected resolution in late 2024.

    Tesla
    On December 5, 2023, Tesla and certain of its subsidiaries filed a claim in the UK High Court against the Company and Avanci. The claim alleges invalidity of three of the Company’s patents relating to 5G standards: European Patent (UK) Nos. 3,718,369, 3,566,413, and 3,455,985. Tesla sought, among other relief, a declaration that the patents at issue are invalid, not essential, and not infringed, revocation of the patents at issue, a declaration that the terms of the Avanci 5G Connected Vehicle platform license are not FRAND, and a determination of FRAND terms for a license between Tesla and Avanci covering its Avanci’s 5G Connected Vehicle platform. On March 8, 2024, the Company filed a jurisdiction challenge; a hearing on the jurisdiction challenge is scheduled to begin on May 20, 2024.
    OTHER
    We are party to certain other disputes and legal actions in the ordinary course of business, including arbitrations and legal proceedings with licensees regarding the terms of their agreements and the negotiation thereof. We do not currently believe that these matters, even if adversely adjudicated or settled, would have a material adverse effect on our financial condition, results of operations or cash flows. None of the preceding matters have met the requirements for accrual or disclosure of a potential range as of March 31, 2024, except as noted above.
    7. INCOME TAXES
    In the three months ended March 31, 2024 and 2023, the Company had an estimated effective tax rate of 19.2% and 14.0%, respectively. The change in effective tax rate is due to a decrease in the amount of Foreign Derived Intangible Income deduction benefit available to the Company. In addition, the Company is subject to an increase in the Global Intangible Low-Tax Income inclusion derived from the increase in French revenue. The effective tax rate in the period ending March 31, 2023, was impacted by losses in certain jurisdictions where the Company recorded a valuation allowance against the related tax benefit. Excluding this valuation allowance, our effective tax rate for the three months ended March 31, 2023 would have been 13.8% respectively. During both the three months ended March 31, 2024 and 2023, the Company recorded discrete net benefits of $1.7 million and $1.0 million, respectively, primarily related to share-based compensation.
    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, 2024 and 2023, the Company paid approximately $9.3 million and $4.4 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):

    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):

    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.

    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 2023 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 Form 10-Q, we refer to “recurring revenues” and “catch-up revenues.” For variable and dynamic fixed-fee license agreements, “catch-up revenues” primarily represents revenue associated with reporting periods prior to the execution of the license agreement, while “recurring revenue” represents revenue associated with reporting periods beginning with the execution of the license agreement. For static fixed-fee license agreements, we typically classify the associated revenue as catch-up revenues.
    Samsung TV Agreement
    In January 2024, we signed a patent license agreement with Samsung Electronics (the "Samsung TV agreement"). The agreement licenses Samsung’s digital TVs and computer display monitors under InterDigital's joint licensing program with Sony and includes licenses to key technologies including ATSC 3.0, as well as licenses under InterDigital’s patents including HEVC, VVC and Wi-Fi.
    Return of Capital to Shareholders
    During the first quarter 2024, we returned $39.2 million to shareholders, including $10.2 million, or $0.40 per share, of cash dividends declared and $29.0 million through the repurchase of 0.3 million shares of common stock.
    During the period April 1, 2024 to April 30, 2024, we repurchased an additional 0.2 million shares for $21.1 million, bringing the year to date total to approximately 0.5 million shares of common stock repurchased. As of April 30, 2024, there was $246.3 million remaining under the share repurchase authorization, which we plan to utilize to periodically repurchase additional common shares. See Part II, Item II - 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, 2024, we had $1.0 billion of cash, restricted cash and short-term investments and an additional $1.2 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 wireless patent license agreement with Samsung.
    87% of our recurring revenue comes from fixed-fee royalties. 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, 2024 and 2023, including the resulting operating cash flow (in thousands):
    For the Three Months Ended March 31,

    Table of Contents
    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, 2024 (in thousands):

    Thereafter2,476 
    Total Revenue$349,921 
    Revenue
    Total revenues of $263.5 million, which includes both recurring and catch-up revenues, increased 30% compared to first quarter 2023 primarily due to catch-up revenues from the Samsung TV agreement recognized in first quarter 2024. First quarter 2024 recurring revenues were $96.9 million, compared to recurring revenues of $101.6 million in first quarter 2023, a 5% year-over-year decrease. In first quarter 2024, revenues (in descending order) from Samsung and Apple each comprised 10% or more of our consolidated revenues. Refer to "Results of Operations --First Quarter 2024 Compared to First Quarter 2023" for further discussion of our 2024 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 inflation, supply chain issues, rising interest rates, labor shortages, and the potential for a recession. These market factors, as well as the impacts of the Ukraine-Russia and Middle East 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 2024 financial results against other periods, the following items should be taken into consideration:
    Revenue
    •Our first quarter 2024 revenues include $166.7 million of catch-up revenues primarily related to the Samsung TV agreement signed in first quarter 2024.
    Operating Expenses
    •During first quarter 2024, we incurred $65.7 million of nonrecurring revenue share costs associated with the catch-up revenues recognized in the period.
    Non-Operating (Expense) Income, Net
    •During first quarter 2024, we recognized a $0.7 million net loss resulting from observable price changes of our long-term strategic investment, which was included within “Other income, net” in the condensed consolidated statement of income.
    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 consolidated financial statements included in our 2023 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 2023 Form 10-K. There have been no material changes to our existing critical accounting policies from the disclosures included in our 2023 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 and 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, 2024 and December 31, 2023, we had the following amounts of cash and cash equivalents, restricted cash and short-term investments (in thousands):
    March 31, 2024December 31, 2023Increase /
    (Decrease)
    Cash and cash equivalents$440,242 $437,076 $3,166

    Total cash, cash equivalents, restricted cash and short-term investments$1,005,583 $1,012,241 $(6,658)
    The net decrease in cash, cash equivalents, restricted cash and short-term investments was attributable to cash used in financing activities of $49.3 million and cash used in investing activities of $7.8 million, excluding sales and purchases of short-term investments, partially offset by cash provided by operating activities of $50.8 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 2024 and 2023 (in thousands) were as follows:

    Table of Contents
    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 $78.6 million change in net cash provided by (used in) operating activities was driven by higher cash receipts primarily due to new patent license agreements signed in first quarter 2024 and due timing of cash receipts related to existing patent license agreements, partially offset by increased cash operating expenses primarily due to increased revenue share costs from new patent license agreements. 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, 2024 and 2023 (in thousands):

    ______________________________
    (a) Cash operating expenses include operating expenses less depreciation and disposals of fixed assets, amortization of patents, and non-cash compensation. Includes revenue share costs of $69.0 million and $1.1 million in first quarter 2024 and 2023, 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 2024 was $16.8 million, a $31.2 million change from $14.5 million of net cash used in investing activities in first quarter 2023. During first quarter 2024, we sold $24.6 million of short-term marketable securities, net of purchases, and capitalized $9.4 million of patent costs and property and equipment purchases. During first quarter 2023, we purchased $6.0 million of short-term marketable securities, net of sales, and capitalized $8.5 million of patent costs and property and equipment purchases.
    Net cash used in financing activities for first quarter 2024 was $49.3 million, a change of $168.8 million from $218.1 million the first quarter 2023. This change was primarily attributable to a $174.5 million decrease in share repurchases, of which $203.4 million was related to the Company's modified "Dutch auction" tender offer in first quarter 2023.
    Other
    Our combined short-term and long-term deferred revenue balance as of March 31, 2024 was approximately $349.9 million, a net decrease of $27.5 million from December 31, 2023. This decrease in deferred revenue was primarily due to amortization of deferred revenue recognized in the period, partially offset by cash receipts on existing patent license agreements.
    Based on current license agreements, we expect the amortization of dynamic fixed-fee royalty payments to reduce the March 31, 2024 deferred revenue balance of $349.9 million by $156.0 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.
    Commencing on March 1, 2024, the 2024 Notes became convertible at any time prior to 5:00 p.m., New York City time, on the second scheduled trading day immediately preceding the maturity date of the 2024 Notes. Additionally, from the period April 1, 2024 through June 30, 2024, 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 and 2024 Notes, which for purposes of this discussion are also referred to as the "Convertible Notes", are included in the dilutive earnings per share calculation using the if-converted method. Under the if-converted method, we must assume that conversion of convertible securities occurs at the beginning of the reporting period. The Convertible Notes are convertible into cash up to the aggregate principal amount of the Convertible Notes to be converted. Any remaining obligation of the 2027 Notes may be settled in cash, shares of the Company’s common stock or a combination thereof and any remaining obligation of the 2024 Notes is settled in shares of our common stock. As the principal amount must be paid in cash and only the conversion spread is settled in shares, we only include the net number of incremental shares that would be issued upon conversion. We must calculate the number of shares of our common stock issuable under the terms of the Convertible Notes based on the average market price of our common stock during the applicable reporting period and include that number in the total diluted shares figure for the period.
    At the time we issued the Convertible Notes, we entered into the 2027 Call Spread Transactions and 2024 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 Convertible Notes by, in effect, increasing the conversion price of the Convertible Notes from our economic standpoint. However, under GAAP, since the impact of the 2027 Note Hedge Transactions and 2024 Note Hedge Transactions (together, the "Note Hedge Transactions") is anti-dilutive, we exclude from the calculation of fully diluted shares the number of shares of our common stock that we would receive from the counterparties to these agreements upon settlement.
    During periods in which the average market price of our common stock is above the applicable conversion price of the Convertible Notes ($77.49 per share for the 2027 Notes and $81.29 per share for the 2024 Notes as of March 31, 2024) or above the strike price of the warrants (weighted average of $106.31 per share for the 2027 Warrant Transactions and $109.43 per share for the 2024 Warrant Transactions as of March 31, 2024), the impact of conversion or exercise, as applicable, would be dilutive and such dilutive effect is reflected in diluted earnings per share. As a result, in periods where the average market price of our common stock is above the conversion price or strike price, as applicable, under the if-converted method, we calculate 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 include that number in the total diluted shares outstanding for the period.
    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 fully diluted earnings per share calculation. As described in Note 5, "Obligations," the Convertible Notes are convertible into cash up to the aggregate principal amount of the Convertible Notes to be converted and any remaining obligation may be in cash, shares of the Company’s common stock or a combination thereof ("net share settlement"). Assuming net share settlement upon conversion, the following tables illustrate how, based on the $460.0 million aggregate principal amount of the 2027 Notes and the $126.2 million aggregate principal amount of the 2024 Notes outstanding as of March 31, 2024, and the approximately 5.9 million warrants related to the 2027 Notes and the 1.6 million warrants remaining related to the 2024 Notes, outstanding as of the same date, changes in our stock price would affect (i) the number of shares issuable upon conversion of the Convertible Notes, (ii) the number of shares issuable upon exercise of the warrants subject to the 2027 Warrant Transactions and 2024 Warrant Transactions (together, the "Warrant Transactions"), (iii) the number of additional shares deemed outstanding with respect to the Convertible Notes, after applying the if-converted method, for purposes of calculating diluted earnings per share ("Total If-Converted Method Incremental Shares"), (iv) the number of shares of our common stock deliverable to us upon settlement of the Note Hedge Transactions and (v) the number of shares issuable upon concurrent conversion of the Convertible Notes, exercise of the warrants subject to the Warrant Transactions, and settlement of the Note Hedge Transactions (in thousands):

    (a)    Catch-up revenues are comprised of past patent royalties and revenues from static agreements.
    Total revenues of $263.5 million, which includes both recurring and catch-up revenues, increased 30% from first quarter 2023 primarily due to catch-up revenues from the Samsung TV agreement signed in first quarter 2024, partially offset by catch-up revenues related to the Lenovo proceedings recognized in first quarter 2023.
    Recurring revenues decreased 5% to $96.9 million, compared to $101.6 million in first quarter 2023. The decrease was primarily driven by the expiration of the Huawei patent license agreement, partially offset by recurring revenues from seven new patent license agreements signed in first quarter 2024.
    In first quarter 2024 and 2023, 84% and 67%, respectively, of our total revenue was attributable to licensees that individually accounted for 10% or more of our total revenue. In first quarter 2024 and 2023, the following licensees accounted for 10% or more of our total revenue:

    Table of Contents
    Operating expenses increased to $159.8 million in first quarter 2024 from $83.1 million in first quarter 2023. The $76.7 million increase in total operating expenses was primarily due to changes in the following items (in thousands):
     Increase/(Decrease)
    Revenue share
    $67,911 
    Intellectual property enforcement11,527 
    Performance-based compensation3,421 
    Net litigation fee reimbursement(5,636)
    Patent impairment(2,500)
    Other1,969 
    Total increase in operating expenses$76,692 
    The $76.7 million increase in operating expenses was driven by a $67.9 million increase in revenue share costs primarily related to the Samsung TV agreement and a $3.4 million increase in performance-based compensation due to higher accrual rates driven by licensing successes. Additionally, intellectual property enforcement costs increased $11.5 million due to costs associated with the Lenovo and Oppo proceedings and the Samsung arbitration. These increases were partially offset by one-time items recognized in first quarter 2023, including a $5.6 million net litigation fee reimbursement and a $2.5 million patent impairment on our patents held for sale.
    Research and portfolio development expense: Research and portfolio development expense were flat compared to first quarter 2023.
    Licensing expense: Licensing expense increased $75.2 million primarily driven by the above-noted increased revenue share costs and intellectual property enforcement costs, partially offset by the one-time net litigation fee reimbursement.
    General and administrative expense: General and administrative expense increased $1.5 million primarily due to the above-noted increased performance-based compensation costs.
    Non-Operating (Expense) Income, net
    The following table compares first quarter 2024 non-operating expense, net to first quarter 2023 non-operating income, net (in thousands):
    Three months ended March 31,

    Interest expense$(11,922)$(12,087)$165 1 %

    Other (expense) income, net(2,531)1,511 (4,042)(268)%
    Total non-operating (expense) income, net$(2,675)$1,104 $(3,779)(342)%
    Interest expense and interest and investment income were flat compared to first quarter 2023. The change in Other (expense) income, net was primarily due to a foreign currency translation net loss arising from translation of our foreign subsidiaries of $2.4 million in first quarter 2024, compared to a $0.7 million net gain in first quarter 2023.
    Income taxes
    In first quarter 2024 and 2023, based on the statutory federal tax rate net of discrete federal and state taxes, we had an effective tax rate of 19.2% and 14.0%, respectively. The change in effective tax rate is due to a decrease in the amount of Foreign Derived Intangible Income deduction benefit available to the Company. In addition, the Company is subject to an increase in the Global Intangible Low-Tax Income inclusion derived from the increase in French revenue. The effective tax rate in the period ending March 31, 2023, was impacted by losses in certain jurisdictions where the Company recorded a valuation allowance against the related tax benefit. Excluding this valuation allowance, our effective tax rate for the three months ended March 31, 2023 would have been 13.8% respectively.
