NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 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 June 30, 2024, the results of our operations for the three and six months ended June 30, 2024 and 2023 and our cash flows for the six months ended June 30, 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 six months ended June 30, 2024 and 2023 (in thousands):


	Six Months Ended June 30,

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.

During the six months ended June 30, 2024, we recognized $84.9 million of revenue that had been included in deferred revenue as of the beginning of the period. As of June 30, 2024, we had contract assets of $201.9 million included within "Accounts receivable" in the condensed consolidated balance sheet. As of December 31, 2023, we had contract assets of $94.6 million included within "Accounts receivable" in the condensed consolidated balance sheet.

Contracted Revenue

Based on contracts signed and committed as of June 30, 2024, we expect to recognize the following revenue from dynamic fixed-fee royalty payments over the term of such contracts (in thousands):

Cash, Cash Equivalents and Restricted Cash

Cash, cash equivalents and restricted cash currently consists of money market and demand accounts. The following table provides a reconciliation of total cash, cash equivalents and restricted cash as of June 30, 2024, December 31, 2023 and June 30, 2023 to the captions within the condensed consolidated balance sheets and condensed consolidated statements of cash flows (in thousands):


	June 30,		December 31,		June 30,
	2024		2023		2023
Cash and cash equivalents	$	299,762	$	437,076	$	277,599
Restricted cash included within prepaid and other current assets	9,233		5,885		13,273

Total cash, cash equivalents and restricted cash	$	308,995	$	442,961	$	290,872

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 88% and 84% of our accounts receivable balance, as of June 30, 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.

Table of Contents

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.

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 June 30, 2024 and December 31, 2023 (in thousands):

Non-Recurring Fair Value Measurements

Patents

During first quarter 2023, we incurred a one-time impairment of $2.5 million on our patents held for sale. We determined the fair value based upon evaluation of market conditions.

Investment in Other Entities

During second quarter 2024 and 2023, we recognized gains of $2.2 million and $3.1 million, respectively, resulting from fair value changes of one of our long-term strategic investments, which was included within “Other income, net” in the condensed consolidated statement of income.

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 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 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 September 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 Notes are included in "Current portion of long-term debt" in our condensed consolidated balance sheets as of June 30, 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. 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 June 30, 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 Senior Convertible Notes due in 2024 (the "2024 Notes") that bore 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 matured on June 1, 2024. 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. We repaid the remaining $126.2 million in aggregate principal at maturity on June 1, 2024.

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 covered, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock, in the aggregate, at a strike price that corresponded to the conversion price of the 2024 Notes, subject to adjustment, and were 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.

At maturity on June 1, 2024, the Company issued 0.3 million shares to settle the 2024 Notes that had been converted by holders. This issuance was effectively offset by our receipt of 0.3 million shares from the settlement of the 2024 Note Hedge Transactions. No shares have been issued related to the 2024 Warrant Transactions as of June 30, 2024, and warrants to acquire 1.6 million shares of common stock at an initial strike price of approximately $109.43 per share, subject to adjustment, remain outstanding. The 2024 Warrants settle during the period September 3, 2024 through December 17, 2024.

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 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 June 30, 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.

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 and six months ended June 30, 2024, we recognized $1.0 million and $1.6 million, respectively, of interest expense related to this debt, compared to $1.0 million and $1.3 million during the three and six months ended June 30, 2023, respectively. 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 $12.9 million in payments to CPPIB Credit during the six months ended June 30, 2024 and no payments were made during the six months ended June 30, 2023.

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 June 30, 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 was heard on June 10-14, 2024, and the UK Court of Appeal issued its decision on July 12, 2024. The UK Court of Appeal ruled in favor of InterDigital and awarded the Company an additional amount of $55.2 million to a total of approximately $240.1 million. It rejected Lenovo’s appeal in its entirety and confirmed that Lenovo must pay for all of its past sales starting from 2007 through December 31, 2023. The court also found that Lenovo should pay the Company’s costs for the appeal and reduced the costs that Lenovo was awarded from the initial decision. Lenovo sought permission to appeal, and permission to appeal was refused by the UK Court of Appeals on July 12, 2024. Lenovo has until August 9, 2024 to file a request for an appeal directly with the UK Supreme Court.

Table of Contents

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 was held on July 17, 2024.

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. As relief, InterDigital is seeking: (a) a declaration that the Company is not in breach of its relevant FRAND commitments with respect to Lenovo; (b) to the extent Lenovo does not agree to negotiate a worldwide patent license, does not agree to enter into binding international arbitration to set the terms of a FRAND license, and does not agree to be bound by the terms to be set by the UK High Court in the separately filed UK proceedings described above, an injunction prohibiting Lenovo from continued infringement; (c) damages, including enhanced damages for willful infringement and supplemental damages; and (d) attorneys’ fees and costs.

On September 16, 2020, the Delaware District Court entered a schedule for the case, setting a patent jury trial. On March 8, 2021, the Delaware District Court held a claim construction hearing, and the court issued its order on May 10, 2021, construing various disputed terms. On March 24, 2021, the Delaware District Court consolidated the antitrust proceeding discussed below with this patent proceeding. On April 25, 2022, the parties filed a stipulation to stay only the claims relating to U.S. Patent No. 8,199,726. The stipulation was granted. On January 13, 2023, Lenovo filed a motion to sever and stay the Company’s patent infringement claims, requesting that its Sherman Act and breach of FRAND claims proceed to trial. On June 30, 2023, the parties submitted an update to the Court requesting that the entire case be stayed, and on July 18, 2023, the court ordered that the case be stayed pending resolution of all appeals in the UK proceedings.

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.

On June 22, 2020, the Company filed a motion to dismiss Lenovo’s Sherman Act claims with prejudice, and to dismiss Lenovo’s breach of contract claim with leave to re-file as a counterclaim in the Company’s legal proceeding against Lenovo in the Delaware District Court discussed above.

On March 24, 2021, the Delaware District Court ruled on the Company’s motion to dismiss. 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.

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 June 30, 2024, except as noted above.

7. INCOME TAXES

In the six months ended June 30, 2024 and 2023, the Company had an estimated effective tax rate of 18.6% and 14.5%, 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 revenue in certain foreign jurisdictions. The effective tax rate in the six months ended June 30, 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 six months ended June 30, 2023 would have been 13.0%. During both the six months ended June 30, 2024 and 2023, the Company recorded discrete net benefits of $2.4 million and $1.2 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 six months ended June 30, 2024 and 2023, the Company paid approximately $13.4 million and $6.0 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 June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Net income applicable to InterDigital, Inc.	$	109,664	$	21,783	$	191,316	$	127,042
Weighted-average shares outstanding:
Basic	25,207		26,768		25,359		27,754
Dilutive effect of stock options, RSUs, and warrants	832		632		860		612
Dilutive effect of convertible securities	1,871		255		1,906		128
Diluted	27,910		27,655		28,125		28,494
Earnings per share:
Basic	$	4.35	$	0.81	$	7.54	$	4.58
Dilutive effect of stock options, RSUs, and warrants	(0.12)		(0.02)		(0.21)		(0.10)
Dilutive effect of convertible securities	(0.30)		—		(0.53)		(0.02)
Diluted	$	3.93	$	0.79	$	6.80	$	4.46

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 June 30,		Six Months Ended June 30,
	2024	2023	2024	2023
Restricted stock units and stock options	4	4	2	212

Warrants	7,462	7,488	7,475	7,488
Total	7,466	7,492	7,477	7,700

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. OTHER INCOME, NET

The amounts included in "Other income, net" in the condensed consolidated statements of income for the three and six months ended June 30, 2024 and 2023 were as follows (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Interest and investment income	$	10,125	$	10,254	$	21,903	$	21,934


Other	1,557		4,133		(974)		5,644
Other income, net	$	11,682	$	14,387	$	20,929	$	27,578

The change in Other income, net was primarily due to a foreign currency translation net loss arising from translation of our foreign subsidiaries of $0.9 million and $3.3 million in the three and six months ended June 30, 2024, respectively, compared to net gains of $0.4 million and $1.2 million in three and six months ended June 30, 2023, respectively.

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.

Lenovo Proceedings

On July 12, 2024, the UK’s Court of Appeal handed down its decision in InterDigital’s FRAND licensing case against Lenovo. The Court of Appeal ruled in favor of InterDigital, including raising the amount that Lenovo must pay for a license to InterDigital’s cellular SEP patents. The court rejected Lenovo’s appeal in its entirety and confirmed that Lenovo must pay for all of its past sales starting from 2007. By virtue of this ruling, Lenovo paid an additional amount of more than $55 million, increasing the total lump-sum royalty to $240.1 million for Lenovo’s past sales through December 31, 2023. Lenovo sought permission to appeal, and permission to appeal was refused by the UK Court of Appeals on July 12, 2024. Lenovo has until August 9, 2024 to file a request for an appeal directly with the UK Supreme Court.

Additionally, in May 2024, the Regional Court in Munich held that Lenovo's sales of cellular products on or after January 1, 2024 infringe InterDigital’s patent-in-suit covering 4G and 5G devices, that we have acted in a FRAND manner at all times, and that Lenovo is an unwilling licensee who has not acted in line with widely recognized FRAND principles. This is a first instance decision which can be appealed.

Google Agreement

In June 2024, we signed a new device license agreement with Google. The agreement licenses a range of devices including Pixel smartphones, Fitbit wearables, and other consumer electronics devices to InterDigital’s cellular wireless, Wi-Fi, and HEVC video patented technologies.

Settlement of the 2024 Notes and 2024 Hedge Transactions

On June 1, 2024, the 2024 Notes matured, and we repaid $126.2 million in aggregate principal in cash and issued 0.3 million common shares to settle the remaining obligation. This issuance was effectively offset by our receipt of 0.3 million shares from the settlement of the 2024 Note Hedge Transactions.

Return of Capital to Shareholders

During the second quarter 2024, we returned $45.2 million to shareholders, including $10.1 million, or $0.40 per share, of cash dividends declared and $35.1 million through the repurchase of 0.3 million shares of common stock.

As of July 31, 2024, there was $232.6 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 June 30, 2024, we had $769.6 million of cash, restricted cash and short-term investments and nearly $1.3 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.

88% 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.

Table of Contents

The following table reconciles the timing differences between cash receipts and recognized revenue during the three and six months ended June 30, 2024 and 2023, including the resulting operating cash flow (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
Cash vs. Non-cash revenue:	2024		2023		2024		2023
Fixed fee cash receipts (a)	$	33,705	$	9,406	$	223,838	$	34,075
Other cash receipts (b)	13,801		11,160		23,978		31,132
Change in deferred revenue	26,866		38,641		54,408		81,407
Change in receivables	78,011		92,756		106,348		183,612
Other (c)	71,110		(50,372)		78,463		(26,262)
Total Revenue	$	223,493	$	101,591	$	487,035	$	303,964
Net cash (used in) provided by operating activities	$	(48,910)	$	(45,440)	$	1,863	$	(73,292)

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

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

(c) The changes in other are primarily driven by customer deposits partially offset by long-term contract assets associated with revenue estimates.

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 June 30, 2024 (in thousands):


	Deferred Revenue
Remainder of 2024	$	88,285
2025	135,651
2026	83,052
2027	12,450
2028	1,141
Thereafter	2,476
Total Revenue	$	323,055

Revenue

Total revenues of $223.5 million, which includes both recurring and catch-up revenues, increased 120% compared to second quarter 2023 primarily due to catch-up revenues resulting from the Lenovo UK proceedings and the Google patent license agreement signed in second quarter 2024. Second quarter 2024 recurring revenues were $95.9 million, compared to recurring revenues of $99.1 million in second quarter 2023. In second quarter 2024, revenues (in descending order) from Lenovo, Apple, and Samsung each comprised 10% or more of our consolidated revenues. Refer to "Results of Operations --Second Quarter 2024 Compared to Second 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.

Table of Contents

Comparability of Financial Results

When comparing second quarter 2024 financial results against other periods, the following items should be taken into consideration:

Revenue

•Our second quarter 2024 revenues include $127.6 million of catch-up revenues primarily related to the Lenovo UK proceedings and the Google agreement signed in second quarter 2024.

Operating Expenses

•During second quarter 2024, we accrued a $3.2 million one-time contra expense for a net litigation fee reimbursement associated with the Lenovo 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 for further information regarding the Lenovo proceedings.

•During second quarter 2024, we incurred $1.4 million of one-time performance-based compensation costs driven by licensing success.

Non-Operating Income (Expense), Net

•During second quarter 2024, we recognized a $2.2 million gain resulting from fair value changes of one of our long-term strategic investments, 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 June 30, 2024 and December 31, 2023, we had the following amounts of cash and cash equivalents, restricted cash and short-term investments (in thousands):


	June 30, 2024		December 31, 2023		Increase / (Decrease)
Cash and cash equivalents	$	299,762	$	437,076	$	(137,314)
Restricted cash included within prepaid and other current assets	9,233		5,885		3,348

Short-term investments	460,581		569,280		(108,699)
Total cash, cash equivalents, restricted cash and short-term investments	$	769,576	$	1,012,241	$	(242,665)

The net decrease in cash, cash equivalents, restricted cash and short-term investments was attributable to cash used in financing activities of $233.3 million and cash used in investing activities of $21.4 million, excluding sales and purchases of short-term investments, partially offset by cash provided by operating activities of $1.9 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 half 2024 and 2023 (in thousands) were as follows:


	Six Months Ended June 30,
	2024		2023		Change
Net cash provided by (used in) operating activities	$	1,863	$	(73,292)	$	75,155

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 $75.2 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 half 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 six months ended June 30, 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. Amount includes revenue share costs of $71.7 million and $1.5 million in first half 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 half 2024 was $97.5 million, a $165.0 million change from $67.5 million of net cash used in investing activities in first half 2023. During first half 2024, we sold $118.9 million of short-term marketable securities, net of purchases, and capitalized $22.6 million of patent costs and property and equipment purchases. During first half 2023, we purchased $46.0 million of short-term marketable securities, net of sales, and capitalized $21.5 million of patent costs and property and equipment purchases.

Net cash used in financing activities for first half 2024 was $233.3 million, a change of $38.1 million from $271.5 million the first half 2023. This change was primarily attributable to a $182.2 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. This change was partially offset by $139.1 million of payments on our long-term debt, of which $126.2 million was related to the maturity of the 2024 Notes.

Other

Our combined short-term and long-term deferred revenue balance as of June 30, 2024 was approximately $323.1 million, a net decrease of $54.4 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 new and existing patent license agreements.

Based on current license agreements, we expect the amortization of dynamic fixed-fee royalty payments to reduce the June 30, 2024 deferred revenue balance of $323.1 million by $156.8 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.

The 2024 Notes matured on June 1, 2024 resulting in 0.3 million of common shares being issued. This issuance was effectively offset by the settlement of the 2024 Note Hedge Transactions resulting in zero net shares being issued on June 1, 2024. Under the 2024 Warrant Transactions, we are required to issue up to 1.6 million shares of common stock at an initial strike price of approximately $109.43 per share. These warrants remain outstanding and will settle, on a net-share basis, during the period September 3, 2024 through December 17, 2024.

From the period January 1, 2024 through September 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 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 2027 Notes are convertible into cash up to the aggregate principal amount 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. 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 2027 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 2027 Notes, we entered into the 2027 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 2027 Notes by, in effect, increasing the conversion price of the 2027 Notes from our economic standpoint. However, under GAAP, since the impact of the 2027 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 2027 Notes (initial conversion price of approximately $77.49 per share), or above the strike price of the warrants (weighted average strike price of $106.31 per share), 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 2027 Notes and the 2027 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 2027 Notes are convertible into cash up to the aggregate principal amount to be converted and any remaining obligation 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 tables illustrate how, based on the $460.0 million aggregate principal amount of the 2027 Notes outstanding as of June 30, 2024, and the approximately 5.9 million warrants related to the 2027 Notes changes in our stock price would affect (i) the number of shares issuable upon conversion of the 2027 Notes, (ii) the number of shares issuable upon exercise of the warrants subject to the 2027 Warrant Transactions, (iii) the number of additional shares deemed outstanding with respect to the 2027 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 2027 Hedge Transactions and (v) the number of shares issuable upon concurrent conversion of the 2027 Notes, exercise of the warrants subject to the 2027 Warrant Transactions, and settlement of the 2027 Hedge Transactions (in thousands):

RESULTS OF OPERATIONS

Second Quarter 2024 Compared to Second Quarter 2023

Revenues

The following table compares second quarter 2024 revenues to second quarter 2023 revenues (in thousands):


	Three Months Ended June 30,

Total revenues	$	223,493	$	101,591	$	121,902	120	%

(a) Catch-up revenues are comprised of past patent royalties and revenues from static agreements.

Total revenues of $223.5 million, which includes both recurring and catch-up revenues, increased 120% from second quarter 2023 primarily due to catch-up revenues from the Lenovo UK proceedings and the Google agreement signed in second quarter 2024.

Recurring revenues were relatively flat decreasing 3% to $95.9 million, as increased CE, IoT/Auto revenue mostly offset the 2023 expiration of Huawei and other agreements.

In second quarter 2024 and 2023, 80% and 78%, respectively, of our total revenue was attributable to licensees that individually accounted for 10% or more of our total revenue. In second quarter 2024 and 2023, the following licensees accounted for 10% or more of our total revenue:


	Three Months Ended June 30,
	2024	2023
Customer A	54%	<10%

General and administrative	14,286		11,693		2,593		22	%

Total Operating expenses	$	89,587	$	78,215	$	11,372	15	%

Table of Contents

Operating expenses increased to $89.6 million in second quarter 2024 from $78.2 million in second quarter 2023. The $11.4 million increase in total operating expenses was primarily due to changes in the following items (in thousands):


	Increase/(Decrease)
Intellectual property enforcement	$	10,911
Performance-based compensation	3,988
Revenue share	2,281
Net litigation fee reimbursement	(5,000)
Other	(808)
Total increase in operating expenses	$	11,372

The $11.4 million increase in operating expenses was driven by an increase in intellectual property enforcement costs of $10.9 million due to costs associated with the Lenovo and Oppo proceedings and the Samsung arbitration. Additionally, there was a $4.0 million increase in performance-based compensation due to higher accrual rates driven by licensing successes and a $2.3 million increase in revenue share costs primarily related to the Samsung TV agreement. These increases were partially offset by a change in the net litigation reimbursement accrual related to the Lenovo proceedings of $3.2 million contra-expense in second quarter 2024 compared to $1.8 million of expense in the second quarter 2023.

Research and portfolio development expense: Research and portfolio development expenses were flat compared to second quarter 2023.

Licensing expense: Licensing expense increased $8.5 million primarily driven by the above-noted increased intellectual property enforcement costs and revenue share costs, partially offset by the one-time net litigation fee reimbursement.

General and administrative expense: General and administrative expense increased by $2.6 million primarily due to the increased performance-based compensation costs.

Non-Operating Income, net

The following table compares second quarter 2024 non-operating income, net to second quarter 2023 (in thousands):


	Three Months Ended June 30,
	2024		2023		Increase/(Decrease)
Interest expense	$	(11,483)	$	(12,141)	$	658	5	%
Interest and investment income	10,125		10,254		(129)		(1)	%


Other income, net	1,557		4,133		(2,576)		(62)	%
Total non-operating income, net	$	199	$	2,246	$	(2,047)	(91)	%

Interest expense and interest and investment income were flat compared to second quarter 2023. The change in Other income, net was primarily due to a foreign currency translation net loss arising from translation of our foreign subsidiaries of $0.9 million in second quarter 2024, compared to a $0.4 million net gain in second quarter 2023 and due to fair value adjustments of our investments resulting in a $2.9 million net gain in second quarter 2024, compared to a $3.9 million net gain in second quarter 2023.

Income taxes

In second 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 18.2% and 16.9%, 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 revenue in certain foreign jurisdictions. The effective tax rate in the three months ended June 30, 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 June 30, 2023 would have been 9.6%.

Total revenues	$	487,035	$	303,964	$	183,071	60	%

(a) Catch-up revenues are comprised of past patent royalties and revenues from static agreements.

Total revenues of $487.0 million, which includes both recurring and catch-up revenues, increased 60% from the first half 2023 primarily due to catch-up revenues from the Lenovo UK proceedings and eight other patent license agreements signed in first half 2024, partially offset by catch-up revenues related to the Lenovo UK proceedings and two previously announced agreements recognized in second quarter 2023.

Recurring revenues decreased 4% to $192.8 million, compared to $200.6 million in first half 2023, with increased CE, IoT/Auto revenue mostly offsetting the 2023 expiration of Huawei and other agreements.

In first half 2024 and 2023, 82% and 69% of our total revenue, respectively, was attributable to companies that individually accounted for 10% or more of our total revenue. In first half 2024 and 2023, the following companies accounted for 10% or more of our total revenue:

Table of Contents

Operating expenses increased 55% to $249.4 million in first half 2024 from $161.3 million in first half 2023. The $88.1 million increase in total operating expenses was primarily due to changes in the following items (in thousands):

Intellectual property enforcement	22,540
Performance-based compensation	7,410
Net litigation fee reimbursement	(10,737)

Other	(1,341)
Total increase in operating expenses	$	88,064

The $88.1 million increase in operating expenses was driven by a $70.2 million increase in revenue share costs primarily related to the Samsung TV agreement and a $7.4 million increase in performance-based compensation due to higher accrual rates driven by licensing successes. Additionally, intellectual property enforcement costs increased $22.5 million due to costs associated with the Lenovo and Oppo proceedings and the Samsung arbitration. These increases were partially offset by a change in the net litigation reimbursement accrual related to the Lenovo proceedings of $3.2 million contra expense in first half 2024 compared to $7.5 million of expense in the first half 2023.

Research and portfolio development expense: Research and portfolio development expense was flat compared to first half 2023.

Licensing expense: Licensing expense increased by $83.7 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: The $4.1 million increase in general and administrative expense primarily resulted from the above-noted increases in performance-based compensation costs.

Interest expense and interest and investment income were flat compared to first half 2023. Other (expense) income, net changed primarily due to a foreign currency translation loss of $3.3 million in the first half 2024 arising from euro translation of our foreign subsidiaries, compared to a foreign currency translation gain of $1.2 million in first half 2023 and due to fair value adjustments of our investments resulting in a $3.5 million net gain in first half 2024, compared to a $4.9 million net gain in first half 2023.

Income taxes

In first half 2024 and 2023, we had an effective tax rate of 18.6% and 14.5%, 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 revenue in certain foreign jurisdictions. The effective tax rate in the six months ended June 30, 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 six months ended June 30, 2023 would have been 13.0%. In the six months ended 2024 and 2023, we recorded a net discrete tax benefit of $2.4 million and $1.2 million, respectively, primarily related to share-based compensation.

Compensation Arrangements

On July 30, 2024, the Human Capital Committee (the “Committee”) of the Board of Directors of the Company amended the terms governing the Company’s performance-based equity awards (“Awards”) to provide that, in the event of a Change in Control (as defined in the Company’s 2017 Equity Incentive Plan, as amended (the “Plan”)), such Awards 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. Additionally, the terms governing Awards of Options (as defined in the Plan) will be amended to remove the requirement that shares of the Company’s stock issued upon settlement of an Option must not be disposed or transferred by the holder for two years following the vesting date of such Option. These amendments will apply to all outstanding and all future performance-based awards issued under the Plan. All other terms of the awards, including the service-based vesting schedules initially applicable to such Awards and any other provisions relating to termination following a Change in Control, remain unchanged.

Additionally, on July 30, 2024, the Committee amended the Company’s Executive Severance and Change in Control Policy (the "Policy") to provide that, in the case of a COC Qualified Termination (as defined in the Policy), “Tier 1” employees of the Company, currently consisting solely of the Company’s Chief Executive Officer, will receive a lump sum payment of (i) 200% of the executive’s base salary, decreased from 250%, and (ii) 200% of the executive’s target bonus under the Company’s short-term incentive plan, increased from 100%. All other terms of the Policy, including other amounts payable upon a COC Qualified Termination, remain unchanged.

The amendments described herein are qualified entirely by reference to the amended forms of Award agreement and the amended Policy, each of which is filed as an exhibit to this Quarterly Report on Form 10-Q.
