INTERDIGITAL, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2023

(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 September 30, 2023, the results of our operations for the three and nine months ended September 30, 2023 and 2022 and our cash flows for the nine months ended September 30, 2023 and 2022. 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, 2022 (our “2022 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 15, 2023. Definitions of capitalized terms not defined herein appear within our 2022 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 2022 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.

During 2022, the Company made reclassifications between the operating expenses lines on the consolidated income statement in order to more clearly reflect the Company’s investments to create and protect the value of our innovations. The Company grouped research and portfolio related costs within the line "Research and portfolio development", previously referred to as "Development", which resulted in reclassifying certain portfolio related costs out of the "Licensing" line, previously referred to as "Patent administration and licensing", and into "Research and portfolio development." The impact of this reclassification was $28.3 million and $83.0 million for the three and nine months ended September 30, 2022, respectively. Additionally, the previous "Selling, general, and administrative" line is now referred to as "General and administrative".

2. REVENUE

Disaggregated Revenue

The following table presents the disaggregation of our revenue for the three and nine months ended September 30, 2023 and 2022 (in thousands):

	Three months ended September 30,

	Nine months ended September 30,
	2023		2022		Total Increase/(Decrease)
Recurring revenues:
Smartphone	$	260,882	$	262,323	$	(1,441)	(1)	%
CE, IoT/Auto	43,177		37,040		6,137		17	%
Other	1,063		911		152		17	%
Total recurring revenues	305,122		300,274		4,848		2	%
Catch-up revenues a	138,948		40,465		98,483		243	%
Total revenues	$	444,070	$	340,739	$	103,331	30	%

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

During the nine months ended September 30, 2023, we recognized $145.7 million of revenue that had been included in deferred revenue as of the beginning of the period. As of September 30, 2023, we had contract assets of $46.1 million and $43.7 million included within "Accounts receivable" and "Other non-current assets, net" in the condensed consolidated balance sheet, respectively. As of December 31, 2022, we had contract assets of $32.9 million and $2.5 million included within "Accounts receivable" and "Other non-current assets, net" in the condensed consolidated balance sheet, respectively.

Contracted Revenue

Based on contracts signed and committed as of September 30, 2023, we expect to recognize the following revenue from dynamic fixed-fee royalty payments over the term of such contracts (in thousands):

	Revenue (a)
Remainder of 2023	$	92,458
2024	309,264
2025	296,060
2026	227,395
2027	225,034
2028 and Thereafter	472,696
Total Revenue	$	1,622,907

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

3. INCOME TAXES

In the nine months ended September 30, 2023 and 2022, the Company had an estimated annual effective tax rate of 14.7% and 22.4%, respectively. The change in effective tax rate is due to an increase in the amount of Foreign Derived Intangible Income deduction benefit available to the Company due to higher taxable income inclusive of timing differences between the recognition of book and tax revenue. Additionally, the effective tax rate in both periods was impacted by losses in certain jurisdictions where the Company presently has recorded a valuation allowance against the related tax benefit. Excluding this valuation allowance, our effective tax rate for the nine months ended September 30, 2023 and 2022 would have been 13.4% and 18.1%, respectively. During the nine months ended September 30, 2023, the Company recorded a discrete net benefit of $2.9 million primarily related to share-based compensation and foreign royalty withholding tax that was previously non-creditable. The prior period included a net discrete tax expense of $2.3 million primarily related to the extinguishment of long-term debt recognized during second quarter of 2022.

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 nine months ended September 30, 2023 and 2022, the Company paid approximately $8.4 million and $3.7 million, respectively, in foreign source creditable withholding tax.

4. 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 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 September 30,				Nine months ended September 30,
	2023		2022		2023		2022
Net income applicable to InterDigital, Inc.	$	47,941	$	22,222	$	174,983	$	61,285
Weighted-average shares outstanding:
Basic	26,285		29,659		27,259		30,255
Dilutive effect of stock options, RSUs, convertible securities and warrants	1,527		281		1,002		383
Diluted	27,812		29,940		28,261		30,638
Earnings per share:
Basic	$	1.82	$	0.75	$	6.42	$	2.03
Dilutive effect of stock options, RSUs, convertible securities and warrants	(0.10)		(0.01)		(0.23)		(0.03)
Diluted	$	1.72	$	0.74	$	6.19	$	2.00

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 September 30,		Nine months ended September 30,
	2023	2022	2023	2022
Restricted stock units and stock options	1	537	142	493
Warrants	7,488	7,488	7,488	6,096
Total	7,489	8,025	7,630	6,589

12

Convertible Notes and Warrants

Refer to Note 7, "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.

5. 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 judgement 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. A form of order hearing took place in May 2023 regarding the license terms, interest, costs, and permission to appeal. 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.

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.

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.

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 September 30, 2023, except as noted above.

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

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 September 30, 2023, December 31, 2022 and September 30, 2022 to the captions within the condensed consolidated balance sheets and condensed consolidated statements of cash flows (in thousands):

	September 30, 2023		December 31, 2022		September 30, 2022
Cash and cash equivalents	$	518,483	$	693,479	$	539,651
Restricted cash included within prepaid and other current assets	7,229		9,682		8,253
Restricted cash included within other non-current assets	—		—		1,081
Total cash, cash equivalents and restricted cash	$	525,712	$	703,161	$	548,985

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, such as United States government instruments.

Our accounts receivable and contract assets are derived principally from patent license and technology solutions agreements. Four licensees comprised 71% and 76% of our net accounts receivable balance as of September 30, 2023 and December 31, 2022, 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.

16

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 September 30, 2023 and December 31, 2022 (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.

17

During fourth quarter 2021, we renewed our multi-year, worldwide, non-exclusive patent license agreement with Sony Corporation of America ("Sony"). A portion of the consideration for the agreement was in the form of patents, which we received in March 2022. We have determined the fair value of the patents for determining the transaction price for revenue recognition purposes, which was estimated to be $30.1 million utilizing the income and market approaches. The value is amortized as a non-cash expense over the patents' estimated useful lives.

Investment in Other Entities

During third quarter 2023, we recognized a $6.1 million gain resulting from observable price changes of our long-term strategic investments, which was included within “Other income (expense), net” in the condensed consolidated statement of income.

During second quarter 2023, we recognized a $3.1 million gain resulting from fair value changes of one of our long-term strategic investments, which was included within “Other income (expense), net” in the condensed consolidated statement of income.

During second quarter 2022, we recognized a $1.6 million gain resulting from observable price changes of our long-term strategic investments, which were included within “Other income (expense), net” in the condensed consolidated statement of income.

7. 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).

18

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 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 at an initial strike price of $106.37 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.

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 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, the Company repurchased $273.8 million in aggregate principal amount of the 2024 Notes in privately negotiated transactions concurrently with the offering of the 2027 Notes. $126.2 million in aggregate principal amount of the 2024 Notes remained outstanding as of September 30, 2023. 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 reduced the number of warrants exercisable under the 2024 Warrant 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 September 30, 2023. As of September 30, 2023, the warrants under the 2024 Warrant Transactions had a strike price of approximately $109.43 per share, as adjusted.

The following table reflects the carrying value of our Convertible Notes long-term debt as of September 30, 2023 and December 31, 2022 (in thousands):

	September 30, 2023		December 31, 2022

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 September 30, 2023 and December 31, 2022 is disclosed within Note 6, "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.

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 nine months ended September 30, 2023, we recognized $1.1 million and $2.5 million, respectively, of interest expense related to this debt, compared to $1.0 million and $2.9 million during the three and nine months ended September 30, 2022, 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.

20

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 September 30, 2023, the contingent consideration liability from the revenue-sharing arrangement was deemed not probable and is therefore not reflected within the consolidated financial statements.

8. VARIABLE INTEREST ENTITIES

As further discussed below, we are the primary beneficiary of one variable interest entity. As of September 30, 2023, the book value of the assets and liabilities associated with this variable interest entity included in our condensed consolidated balance sheet were $11.4 million and $0.7 million, respectively. Assets included $2.5 million of cash and cash equivalents, $0.1 million of prepaid and other current assets, and $8.8 million of patents, net. As of December 31, 2022, the book value of the assets and liabilities associated with this variable interest entity included in our condensed consolidated balance sheet were $17.5 million and $1.8 million, respectively. Assets included $4.4 million of cash and cash equivalents, $4.0 million of accounts receivable and prepaid and other current assets, and $9.1 million of patents, net.

Convida Wireless

Convida Wireless was launched in 2013, and most recently renewed in 2021, to combine Sony's consumer electronics expertise with our pioneering IoT expertise to drive IoT communications and connectivity. Based on the terms of the agreement, the parties will contribute funding and resources for additional research and platform development, which we performed.

Convida Wireless is a variable interest entity. Based on our provision of research and platform development services to Convida Wireless, we determined that we were the primary beneficiary for accounting purposes and consolidated Convida Wireless through September 30, 2023. For the three and nine months ended September 30, 2023, we allocated approximately $0.8 million and $3.0 million, respectively, of Convida Wireless's net loss to noncontrolling interests held by other parties and for the three and nine months ended September 30, 2022, we allocated approximately $0.5 million and $1.2 million, respectively.

In October 2023, Convida Wireless appointed a President and Chief Licensing Officer who will be responsible for directing the operating activities of Convida, including research and platform development services. Accordingly, we expect to deconsolidate Convida Wireless during fourth quarter 2023.

9. OTHER INCOME (EXPENSE), NET

The amounts included in "Other income (expense), net" in the condensed consolidated statements of income for the three and nine months ended September 30, 2023 and 2022 were as follows (in thousands):

	Three months ended September 30,				Nine months ended September 30,
	2023		2022		2023		2022

Other income (expense), net	$	14,725	$	912	$	42,303	$	(15,109)

The changes in Other income (expense), net for the three and nine months ended September 30, 2023 and 2022 were $13.8 million and $57.4 million, respectively. Interest and investment income increased in both three and nine months ended September 30, 2023 and 2022, due to increased short-term investments made by the Company and market conditions driving higher yields on our short-term investments. The change in the nine months ended September 30, 2023 and 2022 was also due to the $11.2 million loss on extinguishment of the 2024 Notes in second quarter 2022, as described further in Note 7, "Obligations".

The changes in Other were primarily due to foreign currency translation arising from euro translation of our foreign subsidiaries and fair value adjustments of our investments.

11.    RESTRUCTURING ACTIVITIES

During second quarter 2021, the Company undertook certain actions in order to increase focus on core technologies and markets.

On June 10, 2021, the Company announced that, as a result of a strategic review of its research and innovation priorities, it commenced the process of a collective economic layoff in which it proposed a reduction in force of its research and innovation unit. All notices of termination have been issued to the impacted employees.

During 2021, Chordant ceased operations. The Company implemented a reduction in workforce action in second quarter 2021.

Additionally, in June 2021, a non-controlled subsidiary that we consolidate for financial statement purposes approved a plan to sell certain patents. The proceeds from the sale of these patents contributed to funding the non-controlled subsidiary's operations.

22

In October 2021, we expanded our restructuring efforts to include general and administrative functions largely centered in the U.S., which resulted in a further reduction in force as well as cuts to our non-labor expenses. These employees were provided notification of termination during fourth quarter 2021.

The Company does not anticipate further restructuring costs at this time, however these charges are estimated based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts incurred for such activities may differ from amounts initially estimated.

As of September 30, 2023 and December 31, 2022, the Company's restructuring liability was $0.2 million and $4.5 million, respectively, and is included in "Other accrued expenses" on our condensed consolidated balance sheet. The following table presents the change in our restructuring liability during the period (in thousands):

Balance as of December 31, 2022	$	4,495

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 2022 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 “catch-up revenues.” Catch-up revenues are comprised of past patent royalties and revenues from static agreements.

Lenovo HEVC Agreement

During third quarter 2023, we signed a multi-year, worldwide, non-exclusive, royalty bearing license with Lenovo ("Lenovo HEVC PLA"), covering InterDigital’s HEVC video patents. The new license resolves all related HEVC litigation. During third quarter 2023, we recognized a total of $40.8 million of revenue from Lenovo, including amounts received under the Lenovo HEVC PLA.

Return of Capital to Shareholders

During the third quarter 2023, the Company returned $66.1 million to shareholders, including $9.3 million, or $0.35 per share, of cash dividends paid and $56.9 million through the repurchase of 0.7 million shares of common stock. Additionally, we announced an increase to the quarterly cash dividend from $0.35 to $0.40 per share, beginning with the dividend paid in fourth quarter 2023.

During the period October 1, 2023 to October 31, 2023, we repurchased an additional 0.3 million shares for $21.9 million under our share repurchase program. As of October 31, 2023, there was $79.9 million remaining under the share repurchase authorization, which we plan to utilize to repurchase additional common shares.

Cash & Short-term Investments

As of September 30, 2023, we had $1.1 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 a patent license agreement with Samsung.

88% of our recurring revenue comes from fixed-fee royalties. Our fixed-fee 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 and nine months ended September 30, 2023 and 2022, including the resulting operating cash flow (in thousands):

	Three months ended September 30,				Nine months ended September 30,
Cash vs. Non-cash revenue:	2023		2022		2023		2022
Fixed fee cash receipts (a)	$	368,608	$	26,662	$	402,683	$	73,804
Other cash receipts (b)	3,684		6,403		34,816		31,615
Change in deferred revenue	(77,474)		(274,034)		3,933		(146,334)
Change in receivables	(167,222)		354,242		16,390		371,930
Other (c)	12,510		1,491		(13,752)		9,724
Total Revenue	$	140,106	$	114,764	$	444,070	$	340,739
Net cash provided by (used in) operating activities	$	310,610	$	(18,729)	$	237,318	$	(70,469)

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

24

When we collect payments on a front-loaded basis, we recognize a deferred revenue liability equal to the cash received and accounts receivable recorded that 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 September 30, 2023 (in thousands):

	Deferred Revenue (a)
Remainder of 2023	$	64,137
2024	134,934
2025	128,791
2026	78,777
2027	12,450
2028 and Thereafter	3,617
Total Revenue	$	422,706

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

Revenue

Third quarter 2023 total revenues of $140.1 million increased 22% from third quarter 2022 primarily due to catch-up revenues recognized from the Lenovo HEVC PLA and one other new agreement signed during third quarter 2023. Third quarter 2023 recurring revenues were $104.5 million, compared to recurring revenues of $101.0 million in third quarter 2022, a 3% year-over-year increase. In third quarter 2023, revenues (in descending order) from Lenovo, Apple, Samsung, and Xiaomi each comprised 10% or more of our consolidated revenues. Refer to "Results of Operations --Third Quarter 2023 Compared to Third Quarter 2022" for further discussion of our 2023 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 Israel-Hamas 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. See the section titled “Risk Factors” in the 2022 Form 10-K.

Comparability of Financial Results

When comparing third quarter 2023 financial results against other periods, the following items should be taken into consideration:

•Our third quarter 2023 revenues include $35.6 million of catch-up revenues related to the Lenovo HEVC PLA and one other new agreement signed in third quarter 2023.

•During third quarter 2023, we recognized a $6.1 million gain resulting from an observable price change of a long-term strategic investment, which was included within “Other income (expense), net” in the condensed consolidated statement of income.

•During third quarter 2023, we incurred $5.1 million of one-time supplemental compensation costs driven by licensing success.

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 September 30, 2023 and December 31, 2022, we had the following amounts of cash and cash equivalents, restricted cash and short-term investments (in thousands):

	September 30, 2023		December 31, 2022		Increase /(Decrease)
Cash and cash equivalents	$	518,483	$	693,479	$	(174,996)
Restricted cash included within prepaid and other current assets	7,229		9,682		(2,453)
Short-term investments	565,436		508,298		57,138
Total cash, cash equivalents, restricted cash and short-term investments	$	1,091,148	$	1,211,459	$	(120,311)

The net decrease in cash, cash equivalents, restricted cash and short-term investments was attributable to cash used in financing activities of $340.5 million and cash used in investing activities of $30.6 million, excluding sales and purchases of short-term investments, partially offset by cash provided by operating activities of $237.3 million. Refer to the sections below for further discussion of these items.

Cash flows from operating activities

Cash flows provided by (used in) operating activities in the first nine months 2023 and 2022 were as follows (in thousands):

	Nine months ended September 30,
	2023		2022		Change
Net cash provided by (used in) operating activities	$	237,318	$	(70,469)	$	307,787

26

Our cash flows provided by (used in) operating activities are principally driven by cash receipts from patent license agreements, offset by cash operating expenses and income tax payments. The $307.8 million change in net cash provided by (used in) operating activities was primarily driven by cash receipts from the Lenovo UK proceedings, Lenovo HEVC PLA, and seven other new patent license agreements signed in the last twelve months, as well as timing of cash receipts under existing agreements. The increase in cash receipts was partially offset by tax payments made in first nine months 2023 and an increase in cash operating expenses. The table below sets forth the significant items comprising our cash flows provided by (used in) operating activities during the nine months ended September 30, 2023 and 2022 (in thousands):

	Nine months ended September 30,
	2023		2022		Change
Total Cash Receipts	$	437,499	$	105,419	$	332,080
Cash Outflows:
Cash operating expenses a	159,601		152,032		7,569
Income taxes paid b	30,117		4,585		25,532
Total cash outflows	189,718		156,617		33,101
Other working capital adjustments	(10,463)		(19,271)		8,808
Cash flows provided by (used in) operating activities	$	237,318	$	(70,469)	$	307,787

______________________________

(a) Cash operating expenses include operating expenses less depreciation and disposals of fixed assets, amortization of patents, non-cash compensation and non-cash impairment charges.

(b) Income taxes paid include foreign withholding taxes.

Cash flows from investing and financing activities

Net cash used in investing activities for first nine months 2023 was $74.3 million, a $48.9 million decrease from $123.2 million in first nine months 2022. During first nine months 2023, we purchased $43.7 million of short-term marketable securities, net of sales, and capitalized $31.2 million of patent costs and property and equipment purchases. During first nine months 2022, we purchased $92.1 million of short-term marketable securities, net of sales, and capitalized $31.1 million of patent costs and property and equipment purchases.

Net cash used in financing activities for first nine months 2023 was $340.5 million, a change of $369.9 million from net cash provided by financing activities of $29.4 million the first nine months 2022. This change was primarily attributable to a $228.3 million increase in share repurchases in first nine months 2023 compared to first nine months 2022, of which $203.4 million was related to the Company's modified "Dutch auction" tender offer in first quarter 2023. The change was also due to net proceeds of $139.2 million from the debt refinancing during second quarter 2022.

Other

Our combined short-term and long-term deferred revenue balance as of September 30, 2023 was approximately $422.7 million, a net decrease of $3.9 million from December 31, 2022. 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 September 30, 2023 deferred revenue balance of $422.7 million by $167.6 million over the next twelve months.

Convertible Notes

See Note 7, “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.

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 September 30, 2023) or above the strike price of the warrants ($106.37 per share for the 2027 Warrant Transactions and $109.43 per share for the 2024 Warrant Transactions as of September 30, 2023), 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 7, "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 September 30, 2023, 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:

RESULTS OF OPERATIONS

Third Quarter 2023 Compared to Third Quarter 2022

Revenues

The following table compares third quarter 2023 revenues to third quarter 2022 revenues (in thousands):

	Three months ended September 30,
	2023		2022		Increase/(Decrease)
Recurring revenues:
Smartphone	$	88,376	$	87,141	$	1,235	1	%
CE, IoT/Auto	15,659		13,905		1,754		13	%
Other	441		—		441		100	%
Total recurring revenues	104,476		101,046		3,430		3	%
Catch-up revenues a	35,630		13,718		21,912		160	%
Total revenues	$	140,106	$	114,764	$	25,342	22	%

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

Total revenues of $140.1 million increased $25.3 million primarily due to catch-up revenues related to the Lenovo HEVC PLA and one other new agreement, partially offset by catch-up revenues from connected automobile license agreements recognized in third quarter 2022. Recurring revenues were relatively flat compared to third quarter 2022.

In third quarter 2023 and 2022, 78% and 70%, respectively, of our total revenue was attributable to licensees that individually accounted for 10% or more of our total revenue. In third quarter 2023 and 2022, the following licensees accounted for 10% or more of our total revenue:

	Three months ended September 30,
	2023	2022
Customer A	29%	—%
Customer B	24%	30%
Customer C	14%	17%
Customer D	11%	13%

Operating Expenses

The following table summarizes the changes in operating expenses between third quarter 2023 and third quarter 2022 by category (in thousands):

	Three months ended September 30,
	2023		2022		Increase/(Decrease)
Research and portfolio development	$	50,253	$	50,116	$	137	—	%
Licensing	21,522		18,393		3,129		17	%
General and administrative	14,678		14,418		260		2	%
Total Operating expenses	$	86,453	$	82,927	$	3,526	4	%

30

Operating expenses increased to $86.5 million in third quarter 2023 from $82.9 million in third quarter 2022. The $3.5 million increase in total operating expenses was primarily due to changes in the following items (in thousands):

	Increase/(Decrease)
Intellectual property enforcement	$	2,320
Other	1,206
Total increase in operating expenses	$	3,526

The $3.5 million increase in operating expenses was primarily due to a $2.3 million increase in intellectual property enforcement costs driven by costs from the Samsung arbitration and Oppo proceedings, partially offset by decreased costs from the Lenovo proceedings.

Research and portfolio development expense: Research and portfolio development expense was relatively flat compared to third quarter 2022.

Licensing expense: Licensing expense increased $3.1 million primarily due to the above-noted increase in intellectual property enforcement costs.

General and administrative expense: General and administrative expense was relatively flat compared to third quarter 2022.

Non-Operating Income (Expense), net

The following table compares third quarter 2023 non-operating income (expense), net to third quarter 2022 non-operating income (expense), net (in thousands):

	Three months ended September 30,
	2023		2022		Increase/(Decrease)
Interest expense	$	(12,683)	$	(7,659)	$	(5,024)	(66)	%
Interest and investment income	11,763		4,421		7,342		166	%
Other	2,962		(3,509)		6,471		184	%
Total non-operating income (expense), net	$	2,042	$	(6,747)	$	8,789	130	%

Interest expense increased $5.0 million primarily due to significant financing expense resulting from a previously announced patent license agreement. The $7.3 million increase in interest and investment income was primarily due to increased short-term investments made by the Company and market conditions driving higher yields from the short-term investments. The change in Other was primarily due to a $6.1 million gain resulting from an observable price change of a long-term strategic investment.

Income taxes

In third quarter 2023 and 2022, based on the statutory federal tax rate net of discrete federal and state taxes, we had an effective tax rate of 15.3% and 13.2%, respectively. The change in effective tax rate is due to a change in the amount of Foreign Derived Intangible Income deduction available to the Company due to an increase in taxable income for the timing difference between the recognition of book and tax revenue. The effective tax rate in both periods was impacted by losses in certain jurisdictions where the Company presently has recorded a valuation allowance against the related tax benefit, as well as by the foreign-derived intangible income deduction and non-deductible compensation. Excluding this valuation allowance, our third quarter 2023 and 2022 effective tax rate would have been 14.4% and 7.5%, respectively.

First Nine Months 2023 Compared to First Nine Months 2022

Revenues

The following table compares first nine months 2023 revenues to first nine months 2022 revenues (in thousands):

	Nine months ended September 30,
	2023		2022		Total Increase/(Decrease)
Recurring revenues:
Smartphone	$	260,882	$	262,323	$	(1,441)	(1)	%

Total revenues	$	444,070	$	340,739	$	103,331	30	%

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

Total revenues of $444.1 million increased 30% from $340.7 million in the first nine months of 2022 primarily due to catch-up revenues from Lenovo. Recurring revenues were relatively flat compared to first nine months 2022.

In first nine months 2023 and first nine months 2022, 79% and 71% of our total revenue, respectively, was attributable to licensees that individually accounted for 10% or more of our total revenue. In first nine months 2023 and first nine months 2022, the following licensees accounted for 10% or more of our total revenue:

	Nine months ended September 30,

Operating Expenses

The following table summarizes the changes in operating expenses between first nine months 2023 and first nine months 2022 by category (in thousands):

	Nine months ended September 30,
	2023		2022		Increase/(Decrease)
Research and portfolio development	$	149,560	$	139,470	$	10,090	7	%
Licensing	59,534		51,249		8,285		16	%

Total Operating expenses	$	247,780	$	228,817	$	18,963	8	%

32

Operating expenses increased 8% to $247.8 million in first nine months 2023 from $228.8 million in first nine months 2022. The $19.0 million increase in total operating expenses was primarily due to changes in the following items (in thousands):

	Increase/(Decrease)
Share-based compensation	$	11,640
One-time net litigation fee reimbursement	7,537
Fair value changes of deferred compensation liability	4,403
Patent impairment	2,500
Intellectual property enforcement	(3,927)
Restructuring activities	(3,279)
Other	89
Total increase in operating expenses	$	18,963

The $19.0 million increase in operating expenses was primarily due to a $11.6 million increase in share-based compensation costs driven by both higher accrual rates and higher award levels to non-executive employees and a $4.4 million increase from fair value changes of our deferred compensation liability, which was offset by a related gain recorded within "Other income (expense), net" on the investments that we hold under the plan. Additionally, first nine months 2023 included one-time items, including a $7.5 million net litigation fee reimbursement related to the Lenovo proceedings and a $2.5 million impairment on our patents held for sale.

These increases were partially offset by a $3.9 million decrease in intellectual property enforcement costs primarily driven by decreased costs from the Lenovo proceedings and a $3.3 million decrease in non-recurring restructuring activities recognized in first nine months 2022.

Research and portfolio development expense: The $10.1 million increase in research and portfolio development expense primarily resulted from the above-noted increases in share-based compensation, fair value changes of our deferred compensation liability, and patent impairment.

Licensing expense: Licensing expense increased by $8.3 million primarily resulting from the above-noted one-time litigation fee reimbursement and increases in share-based compensation, partially offset by the decrease in intellectual property enforcement costs.

General and administrative expense: The $3.9 million increase in general and administrative expense was primarily driven by the above-noted increases in share-based compensation and fair value changes of our deferred compensation liability.

Restructuring activities: Restructuring expenses associated with our overall restructuring plan decreased due to the plan being substantially complete in 2022.

Non-Operating Income (Expense), net

The following table compares first nine months 2023 non-operating income (expense), net to first nine months 2022 non-operating income (expense), net:

	Nine months ended September 30,
	2023		2022		Increase/(Decrease)
Interest expense	$	(36,911)	$	(19,446)	$	(17,465)	(90)	%
Interest and investment income	33,697		4,927		28,770		584	%
Loss on extinguishment of long-term debt	—		(11,190)		11,190		(100)	%
Other	8,606		(8,846)		17,452		197	%
Total non-operating income (expense), net	$	5,392	$	(34,555)	$	39,947	116	%

Interest expense increased primarily due to significant financing expense resulting from a previously announced patent license agreement and additional interest on the 2027 Notes that were issued during second quarter 2022. Also in second quarter 2022, there was a $11.2 million loss on extinguishment of the 2024 Notes, as described further Note 7, "Obligations" within the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

33

The $28.8 million increase in interest and investment income was primarily due to increased short-term investments made by the Company and market conditions driving higher yields from the short-term investments.

The change in Other was primarily due to fair value adjustments of our investments resulting in a $10.5 million net gain in first nine months 2023, compared to a $1.8 million net loss in first nine months 2022 and due to a foreign currency translation net loss arising from euro translation of our foreign subsidiaries of $1.0 million in first nine months 2023, compared to a $6.7 million net loss in first nine months 2022.

Income taxes

In first nine months 2023 and 2022, we had an effective tax rate of 14.7% and 22.4%, respectively. The change in effective tax rate is due to an increase in the amount of Foreign Derived Intangible Income deduction benefit available to the Company due to higher taxable income inclusive of timing difference between the recognition of book and tax revenue. Additionally, the effective tax rate in both periods was impacted by losses in certain jurisdictions where the Company presently has recorded a valuation allowance against the related tax benefit, as well as by the foreign-derived intangible income deduction and non-deductible compensation. Excluding this valuation allowance, our nine months ended September 30, 2023 and 2022 effective tax rate would have been 13.4% and 18.1%, respectively. In the nine months ended September 30, 2023, we recorded a net discrete tax benefit of $2.9 million primarily related to share-based compensation. The prior period included a net discrete tax expense of $2.3 million primarily related to the extinguishment of long-term debt recognized during second quarter of 2022.

You should carefully consider these factors before making any investment decision with respect to our common stock. These factors, individually or in the aggregate, may cause our actual results to differ materially from our expected and historical results. You should understand that it is not possible to predict or identify all such factors. In addition, you should not place undue reliance on the forward-looking statements contained herein, which are made only as of the date of this Form 10-Q. We undertake no obligation to revise or update publicly any forward-looking statement for any reason, except as otherwise required by law.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There have been no material changes in quantitative and qualitative market risk from the disclosures included in our 2022 Form 10-K.

Item 4. CONTROLS AND PROCEDURES.

The Company’s principal executive officer and principal financial officer, with the assistance of other members of management, have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and to ensure that the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2023, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS.

See Note 5, “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 a description of legal proceedings, which is incorporated herein by reference.

Item 1A. RISK FACTORS.

Reference is made to Part I, Item 1A, “Risk Factors” included in our 2022 Form 10-K for information concerning risk factors, which should be read in conjunction with the factors set forth in the Statement Pursuant to the Private Securities Litigation Reform Act of 1995 -- Forward-Looking Statements in Part I, Item 2 of this Quarterly Report on Form 10-Q. Except as set forth below, there have been no material changes with respect to the risk factors disclosed in our 2022 Form 10-K. You should carefully consider such factors, which could materially affect our business, financial condition or future results. The risks described in this Quarterly Report on Form 10-Q and in the 2022 Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results.

We face risks from doing business and maintaining offices in international markets.

A significant portion of our licensees, potential licensees and customers are international, and our licensees, potential licensees and customers sell their products to markets throughout the world. In addition, in recent years, we have expanded, and we may continue to expand, our international operations, opening offices in China, France, Belgium and Finland. Accordingly, we are subject to the risks and uncertainties of operating internationally. Our international operations could exacerbate the other risk factors we have identified, and we could be affected by a variety of uncontrollable and changing factors, including, but not limited to: difficulty in protecting our intellectual property in foreign jurisdictions; enforcing contractual commitments in foreign jurisdictions or against foreign corporations; government regulations, tariffs and other applicable trade barriers; biased enforcement of foreign laws and regulations to promote industrial or economic policies at our expense; retaliatory practices by foreign actors; currency control regulations; export license requirements and restrictions on the use of technology; social, economic and political instability; costly, time consuming and changing regulatory regimes; natural disasters, acts of terrorism, widespread illness and war; potentially adverse tax consequences; general delays in remittance of and difficulties collecting non-U.S. payments; foreign labor regulations; anti-corruption laws; public health issues; and difficulty in staffing and managing operations remotely. Managing operations and complying with relevant laws and regulations in China may be particularly complex, costly and time-consuming. We also are subject to risks specific to the individual countries in which we and our licensees, potential licensees and customers do business.

In addition, adverse movements in currency exchange rates may negatively affect our business due to a number of situations, including the following:

•If the effective price of products sold by our licensees were to increase as a result of fluctuations in the exchange rate of the relevant currencies, demand for the products could fall, which in turn would reduce our royalty revenues.

•Assets or liabilities of our consolidated subsidiaries may be subject to the effects of currency fluctuations, which may affect our reported earnings.

•Certain of our operating and investing costs, such as foreign patent prosecution, are based in foreign currencies. If these costs are not subject to foreign exchange hedging transactions, strengthening currency values in selected regions could adversely affect our near-term operating expenses, investment costs and cash flows. In addition, continued strengthening of currency values in selected regions over an extended period of time could adversely affect our future operating expenses, investment costs and cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

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 September 30, 2023, the results of our operations for the three and nine months ended September 30, 2023 and 2022 and our cash flows for the nine months ended September 30, 2023 and 2022. 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, 2022 (our “2022 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 15, 2023. Definitions of capitalized terms not defined herein appear within our 2022 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 2022 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.

During 2022, the Company made reclassifications between the operating expenses lines on the consolidated income statement in order to more clearly reflect the Company’s investments to create and protect the value of our innovations. The Company grouped research and portfolio related costs within the line "Research and portfolio development", previously referred to as "Development", which resulted in reclassifying certain portfolio related costs out of the "Licensing" line, previously referred to as "Patent administration and licensing", and into "Research and portfolio development." The impact of this reclassification was $28.3 million and $83.0 million for the three and nine months ended September 30, 2022, respectively. Additionally, the previous "Selling, general, and administrative" line is now referred to as "General and administrative".

As of September 30, 2023, we had contract assets of $46.1 million and $43.7 million included within "Accounts receivable" and "Other non-current assets, net" in the condensed consolidated balance sheet, respectively. As of December 31, 2022, we had contract assets of $32.9 million and $2.5 million included within "Accounts receivable" and "Other non-current assets, net" in the condensed consolidated balance sheet, respectively.

Contracted Revenue

Based on contracts signed and committed as of September 30, 2023, we expect to recognize the following revenue from dynamic fixed-fee royalty payments over the term of such contracts (in thousands):

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

In the nine months ended September 30, 2023 and 2022, the Company had an estimated annual effective tax rate of 14.7% and 22.4%, respectively. The change in effective tax rate is due to an increase in the amount of Foreign Derived Intangible Income deduction benefit available to the Company due to higher taxable income inclusive of timing differences between the recognition of book and tax revenue. Additionally, the effective tax rate in both periods was impacted by losses in certain jurisdictions where the Company presently has recorded a valuation allowance against the related tax benefit. Excluding this valuation allowance, our effective tax rate for the nine months ended September 30, 2023 and 2022 would have been 13.4% and 18.1%, respectively. During the nine months ended September 30, 2023, the Company recorded a discrete net benefit of $2.9 million primarily related to share-based compensation and foreign royalty withholding tax that was previously non-creditable. The prior period included a net discrete tax expense of $2.3 million primarily related to the extinguishment of long-term debt recognized during second quarter of 2022.

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 nine months ended September 30, 2023 and 2022, the Company paid approximately $8.4 million and $3.7 million, respectively, in foreign source creditable withholding tax.

Net Income Per Share

9 Months Ended

Sep. 30, 2023

Earnings Per Share [Abstract]

NET INCOME PER SHARE

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 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 September 30,				Nine months ended September 30,
	2023		2022		2023		2022
Net income applicable to InterDigital, Inc.	$	47,941	$	22,222	$	174,983	$	61,285
Weighted-average shares outstanding:
Basic	26,285		29,659		27,259		30,255
Dilutive effect of stock options, RSUs, convertible securities and warrants	1,527		281		1,002		383
Diluted	27,812		29,940		28,261		30,638
Earnings per share:
Basic	$	1.82	$	0.75	$	6.42	$	2.03
Dilutive effect of stock options, RSUs, convertible securities and warrants	(0.10)		(0.01)		(0.23)		(0.03)
Diluted	$	1.72	$	0.74	$	6.19	$	2.00

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 September 30,		Nine months ended September 30,
	2023	2022	2023	2022
Restricted stock units and stock options	1	537	142	493
Warrants	7,488	7,488	7,488	6,096
Total	7,489	8,025	7,630	6,589

Convertible Notes and Warrants

Refer to Note 7, "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.

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 judgement 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. A form of order hearing took place in May 2023 regarding the license terms, interest, costs, and permission to appeal. 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.

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.

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.

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, such as United States government instruments.

Our accounts receivable and contract assets are derived principally from patent license and technology solutions agreements. Four licensees comprised 71% and 76% of our net accounts receivable balance as of September 30, 2023 and December 31, 2022, 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.

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 September 30, 2023 and December 31, 2022 (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.

During fourth quarter 2021, we renewed our multi-year, worldwide, non-exclusive patent license agreement with Sony Corporation of America ("Sony"). A portion of the consideration for the agreement was in the form of patents, which we received in March 2022. We have determined the fair value of the patents for determining the transaction price for revenue recognition purposes, which was estimated to be $30.1 million utilizing the income and market approaches. The value is amortized as a non-cash expense over the patents' estimated useful lives.

Investment in Other Entities

During third quarter 2023, we recognized a $6.1 million gain resulting from observable price changes of our long-term strategic investments, which was included within “Other income (expense), net” in the condensed consolidated statement of income.

During second quarter 2023, we recognized a $3.1 million gain resulting from fair value changes of one of our long-term strategic investments, which was included within “Other income (expense), net” in the condensed consolidated statement of income.

During second quarter 2022, we recognized a $1.6 million gain resulting from observable price changes of our long-term strategic investments, which were included within “Other income (expense), net” in the condensed consolidated statement of income.

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).

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 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 at an initial strike price of $106.37 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.

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 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, the Company repurchased $273.8 million in aggregate principal amount of the 2024 Notes in privately negotiated transactions concurrently with the offering of the 2027 Notes. $126.2 million in aggregate principal amount of the 2024 Notes remained outstanding as of September 30, 2023. 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 reduced the number of warrants exercisable under the 2024 Warrant 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 September 30, 2023. As of September 30, 2023, the warrants under the 2024 Warrant Transactions had a strike price of approximately $109.43 per share, as adjusted.

The following table reflects the carrying value of our Convertible Notes long-term debt as of September 30, 2023 and December 31, 2022 (in thousands):

	September 30, 2023		December 31, 2022

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 September 30, 2023 and December 31, 2022 is disclosed within Note 6, "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.

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 nine months ended September 30, 2023, we recognized $1.1 million and $2.5 million, respectively, of interest expense related to this debt, compared to $1.0 million and $2.9 million during the three and nine months ended September 30, 2022, 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.

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 September 30, 2023, the contingent consideration liability from the revenue-sharing arrangement was deemed not probable and is therefore not reflected within the consolidated financial statements.

VARIABLE INTEREST ENTITIES

As further discussed below, we are the primary beneficiary of one variable interest entity. As of September 30, 2023, the book value of the assets and liabilities associated with this variable interest entity included in our condensed consolidated balance sheet were $11.4 million and $0.7 million, respectively. Assets included $2.5 million of cash and cash equivalents, $0.1 million of prepaid and other current assets, and $8.8 million of patents, net. As of December 31, 2022, the book value of the assets and liabilities associated with this variable interest entity included in our condensed consolidated balance sheet were $17.5 million and $1.8 million, respectively. Assets included $4.4 million of cash and cash equivalents, $4.0 million of accounts receivable and prepaid and other current assets, and $9.1 million of patents, net.

Convida Wireless

Convida Wireless was launched in 2013, and most recently renewed in 2021, to combine Sony's consumer electronics expertise with our pioneering IoT expertise to drive IoT communications and connectivity. Based on the terms of the agreement, the parties will contribute funding and resources for additional research and platform development, which we performed.

Convida Wireless is a variable interest entity. Based on our provision of research and platform development services to Convida Wireless, we determined that we were the primary beneficiary for accounting purposes and consolidated Convida Wireless through September 30, 2023. For the three and nine months ended September 30, 2023, we allocated approximately $0.8 million and $3.0 million, respectively, of Convida Wireless's net loss to noncontrolling interests held by other parties and for the three and nine months ended September 30, 2022, we allocated approximately $0.5 million and $1.2 million, respectively.

In October 2023, Convida Wireless appointed a President and Chief Licensing Officer who will be responsible for directing the operating activities of Convida, including research and platform development services. Accordingly, we expect to deconsolidate Convida Wireless during fourth quarter 2023.

The changes in Other income (expense), net for the three and nine months ended September 30, 2023 and 2022 were $13.8 million and $57.4 million, respectively. Interest and investment income increased in both three and nine months ended September 30, 2023 and 2022, due to increased short-term investments made by the Company and market conditions driving higher yields on our short-term investments. The change in the nine months ended September 30, 2023 and 2022 was also due to the $11.2 million loss on extinguishment of the 2024 Notes in second quarter 2022, as described further in Note 7, "Obligations".

The changes in Other were primarily due to foreign currency translation arising from euro translation of our foreign subsidiaries and fair value adjustments of our investments.

Restructuring and Related Activities [Abstract]

RESTRUCTURING ACTIVITIES

RESTRUCTURING ACTIVITIES

During second quarter 2021, the Company undertook certain actions in order to increase focus on core technologies and markets.

On June 10, 2021, the Company announced that, as a result of a strategic review of its research and innovation priorities, it commenced the process of a collective economic layoff in which it proposed a reduction in force of its research and innovation unit. All notices of termination have been issued to the impacted employees.

During 2021, Chordant ceased operations. The Company implemented a reduction in workforce action in second quarter 2021.

Additionally, in June 2021, a non-controlled subsidiary that we consolidate for financial statement purposes approved a plan to sell certain patents. The proceeds from the sale of these patents contributed to funding the non-controlled subsidiary's operations.

In October 2021, we expanded our restructuring efforts to include general and administrative functions largely centered in the U.S., which resulted in a further reduction in force as well as cuts to our non-labor expenses. These employees were provided notification of termination during fourth quarter 2021.

The Company does not anticipate further restructuring costs at this time, however these charges are estimated based on information available at the time such charges are recorded. Due to the inherent uncertainty involved in estimating restructuring expenses, actual amounts incurred for such activities may differ from amounts initially estimated.

As of September 30, 2023 and December 31, 2022, the Company's restructuring liability was $0.2 million and $4.5 million, respectively, and is included in "Other accrued expenses" on our condensed consolidated balance sheet. The following table presents the change in our restructuring liability during the period (in thousands):

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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, 2022 (our “2022 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 15, 2023. Definitions of capitalized terms not defined herein appear within our 2022 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.

Estimates

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.

Reclassifications

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

During 2022, the Company made reclassifications between the operating expenses lines on the consolidated income statement in order to more clearly reflect the Company’s investments to create and protect the value of our innovations. The Company grouped research and portfolio related costs within the line "Research and portfolio development", previously referred to as "Development", which resulted in reclassifying certain portfolio related costs out of the "Licensing" line, previously referred to as "Patent administration and licensing", and into "Research and portfolio development." The impact of this reclassification was $28.3 million and $83.0 million for the three and nine months ended September 30, 2022, respectively. Additionally, the previous "Selling, general, and administrative" line is now referred to as "General and administrative".

New Accounting Guidance

No new accounting pronouncement issued or effective during the nine months ended September 30, 2023 has or is expected to have a material impact on our condensed consolidated interim financial statements.
