NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2025
(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, 2025, the results of our operations for the three and nine months ended September 30, 2025 and 2024 and our cash flows for the nine months ended September 30, 2025 and 2024. 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, 2024 (our “2024 Form 10-K”) as filed with the Securities and Exchange Commission (“SEC”) on February 6, 2025. Definitions of capitalized terms not defined herein appear within our 2024 Form 10-K. The results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year. We have one reportable segment.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.
Change in Accounting Policies
There have been no material changes or updates to our existing accounting policies from the disclosures included in our 2024 Form 10-K, except as indicated below in "New Accounting Guidance".
Reclassifications
Certain reclassifications have been made to prior year amounts to conform to the current year presentation.
Supplemental Cash Flow Information
The following table presents additional supplemental cash flow information for the nine months ended September 30, 2025 and 2024 (in thousands):

New Accounting Guidance
Accounting Standards Update: Improvements to Income Tax Disclosures
In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Updates ("ASU") No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments in the ASU enhance income tax disclosures, primarily through standardization, disaggregation of rate reconciliation categories, and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption allowed. We adopted this guidance as of January 1, 2025, and we will include the necessary disclosures in our Annual Report on Form 10-K. The disclosures are required on an annual basis so there was no impact to this Quarterly Report on Form 10-Q.
Accounting Standards Update: Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU No. 2024-03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in the ASU require disclosures about specific types of expenses included in the expense captions presented on the Consolidated Statements of Income, as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption allowed. We are currently evaluating the impact of adoption on our financial disclosures.
Accounting Standards Update: Induced Conversions of Convertible Debt Instruments
In November 2024, the FASB issued ASU No. 2024-04, "Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments". The amendments in the ASU require disclosures for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. ASU 2024-04 is effective for fiscal years beginning after December 15, 2025, with early adoption allowed. We are currently evaluating the impact of adoption on our consolidated financial statements.
Accounting Standards Update: Targeted Improvements to the Accounting for Internal-Use Software
In September 2025, the FASB issued ASU No. 2025-06, "Intangibles—Goodwill and Other Internal-Use Software (Subtopic 350-40)". The amendments in the ASU amends certain aspects of the accounting for and disclosure of software costs under ASC 350-40. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption allowed. We are currently evaluating the impact of adoption on our consolidated financial statements.

(a)    Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.
During the nine months ended September 30, 2025, we recognized $143.8 million of revenue that had been included in deferred revenue as of the beginning of the period. As of September 30, 2025, we had contract assets of $33.6 million included within "Accounts receivable" and $15.0 million included within "Other non-current assets, net" in the condensed consolidated balance sheet. As of December 31, 2024, we had contract assets of $162.8 million included within "Accounts receivable" in the condensed consolidated balance sheet.
Contracted Revenue
Based on contracts signed and committed as of September 30, 2025, we expect to recognize the following revenue from dynamic fixed-fee royalty payments over the term of such contracts (in thousands):

3. CASH, CONCENTRATION OF CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS
Cash, Cash Equivalents, and Restricted Cash
Cash, cash equivalents, and restricted cash currently consist of money market and demand accounts. The following table provides a reconciliation of total cash, cash equivalents, and restricted cash as of September 30, 2025, December 31, 2024, and September 30, 2024 to the captions within the condensed consolidated balance sheets and condensed consolidated statements of cash flows (in thousands):
 September 30,December 31,September 30,

Cash and cash equivalents$840,270 $527,360 $401,090

Total cash, cash equivalents, and restricted cash
$848,630 $551,547 $410,780 
Concentration of Credit Risk and Fair Value of Financial Instruments
Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and accounts receivable. We place our cash equivalents and short-term investments only in highly rated financial instruments and in United States government instruments.
Our accounts receivable and contract assets are derived principally from patent license and technology solutions agreements. Three licensees comprised 65% and 84% of our accounts receivable balances of September 30, 2025 and December 31, 2024, respectively. We perform ongoing credit evaluations of our licensees, who generally include large, multinational, wireless telecommunications and consumer electronics equipment manufacturers. We believe that the book values of our financial instruments approximate their fair values.
Fair Value Measurements
We use various valuation techniques and assumptions when measuring the fair value of our assets and liabilities. We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. This guidance established a hierarchy that prioritizes fair value measurements based on the types of input used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below:
Level 1 Inputs — Level 1 includes financial instruments for which quoted market prices for identical instruments are available in active markets.
Level 2 Inputs — Level 2 includes financial instruments for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets with insufficient volume or infrequent transactions (less active markets) or model-driven valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data, including market interest rate curves, referenced credit spreads and pre-payment rates.
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.

5. OBLIGATIONS
2027 Notes, and Related Note Hedge and Warrant Transactions
On May 27, 2022, we issued $460.0 million in aggregate principal amount of 3.50% Senior Convertible Notes due in 2027 (the "2027 Notes"). The net proceeds from the issuance of the 2027 Notes, after deducting the initial purchasers' transaction fees and offering expenses, were approximately $450.0 million. The 2027 Notes bear interest at a rate of 3.50% per year, payable in cash on June 1 and December 1 of each year, commencing on December 1, 2022, and mature on June 1, 2027, unless earlier redeemed, converted or repurchased.
14

The 2027 Notes will be convertible into cash up to the aggregate principal amount of the 2027 Notes to be converted and in respect of the remainder, if any, of the Company’s obligation in excess of the aggregate principal amount of the 2027 Notes being converted, pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination thereof, at the Company’s election, at an initial conversion rate of 12.9041 shares of common stock per $1,000 principal amount of the 2027 Notes (which is equivalent to an initial conversion price of approximately $77.49 per share). From the period January 1, 2024 through December 31, 2025, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes. As such, the 2027 Notes are included in "Current portion of long-term debt" in our condensed consolidated balance sheets as of September 30, 2025 and December 31, 2024.
The 2027 Notes are the Company’s senior unsecured obligations and rank equally in right of payment with any of the Company’s current and any future senior unsecured indebtedness. The 2027 Notes are effectively subordinated to all of the Company’s future secured indebtedness, if any, to the extent of the value of the related collateral, and the 2027 Notes are structurally subordinated to indebtedness and other liabilities, including trade payables, of the Company’s subsidiaries.
On May 24 and May 25, 2022, in connection with the offering of the 2027 Notes, we entered into convertible note hedge transactions ("2027 Note Hedge Transactions") that cover, subject to customary anti-dilution adjustments, approximately 5.9 million shares of common stock, in the aggregate, at a strike price that initially corresponds to the initial conversion price of the 2027 Notes, subject to adjustment, and are exercisable upon any conversion of the 2027 Notes. Also, on May 24 and May 25, 2022, we entered into privately negotiated warrant transactions ("2027 Warrant Transactions"), whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 5.9 million shares of common stock. As of September 30, 2025, the warrants under the 2027 Warrant Transactions had a weighted average strike price of $105.77 per share, subject to adjustment, and mature beginning September 2027 through April 2028.
2024 Notes, and Related Note Hedge and Warrant Transactions
On June 3, 2019, we issued $400.0 million in aggregate principal amount of Senior Convertible Notes due in 2024 (the "2024 Notes") that bore interest at a rate of 2.00% per year, payable in cash on June 1 and December 1 of each year, commencing on December 1, 2019, and matured on June 1, 2024.
In connection with the offering of the 2024 Notes, we entered into convertible note hedge transactions (collectively, the "2024 Note Hedge Transactions") that covered, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock, in the aggregate, at a strike price that corresponded to the conversion price of the 2024 Notes, subject to adjustment, and were exercisable upon any conversion of the 2024 Notes. We also entered into privately negotiated warrant transactions (collectively, the "2024 Warrant Transactions" and, together with the 2024 Note Hedge Transactions, the "2024 Call Spread Transactions"), whereby we sold warrants to acquire, subject to customary anti-dilution adjustments, approximately 4.9 million shares of common stock at an initial strike price of approximately $109.43 per share, subject to adjustment.
During second quarter 2022, we repurchased $273.8 million in aggregate principal amount of the 2024 Notes in privately negotiated transactions concurrently with the offering of the 2027 Notes. In connection with the partial repurchase of the 2024 Notes, we entered into partial unwind agreements that amended the terms of the 2024 Call Spread Transactions to reduce the number of options corresponding to the principal amount of the repurchased 2024 Notes. The unwind agreements also reduce the number of warrants exercisable under the 2024 Warrant Transactions. As a result of the partial unwind transactions, approximately 3.3 million shares of common stock in the aggregate that were covered under each of the 2024 Note Hedge Transactions and the 2024 Warrant Transactions were unwound.
On June 1, 2024, the 2024 Notes matured and we repaid the remaining $126.2 million in aggregate principal in cash and issued 0.3 million common shares to settle the remaining obligation. This issuance was effectively offset by our receipt of 0.3 million shares from the settlement of the 2024 Note Hedge Transactions. Additionally, the 2024 Warrant Transactions settled, on a net-share basis, during September through December 2024 resulting in the issuance of 0.5 million shares.
The following table reflects the carrying value of our Convertible Notes long-term debt as of September 30, 2025 and December 31, 2024 (in thousands):

Technicolor Patent Acquisition Long-Term Debt
On July 30, 2018, we completed our acquisition of the patent licensing business of Technicolor SA ("Technicolor"), a worldwide technology leader in the media and entertainment sector (the "Technicolor Patent Acquisition"). In conjunction with the Technicolor Patent Acquisition, we assumed Technicolor’s rights and obligations under a joint licensing program with Sony relating to digital televisions and standalone computer display monitors, which commenced in 2015 (the "Madison Arrangement"). An affiliate of CPPIB Credit Investments Inc. ("CPPIB Credit"), a wholly owned subsidiary of Canada Pension Plan Investment Board, is a third-party investor in the Madison Arrangement. CPPIB Credit made certain payments to Technicolor and Sony and agreed to contribute cash to fund certain capital reserve obligations under the arrangement in exchange for a percentage of future revenue, specifically through September 11, 2030 in regard to the Technicolor patents.
Upon our assumption of Technicolor’s rights and obligations under the Madison Arrangement, our relationship with CPPIB Credit meets the criteria in ASC 470-10-25 - Sales of Future Revenues or Various Other Measures of Income ("ASC 470"), which relates to cash received from an investor in exchange for a specified percentage or amount of revenue or other measure of income of a particular product line, business segment, trademark, patent, or contractual right for a defined period. Under this guidance, we recognized the fair value of our contingent obligation to CPPIB Credit, as of the acquisition date, as long-term debt in our condensed consolidated balance sheet. This initial fair value measurement was based on the perspective of a market participant and included significant unobservable inputs which are classified as Level 3 inputs within the fair value hierarchy. The fair value of the long-term debt as of September 30, 2025 and December 31, 2024 is disclosed within Note 3, "Cash, Concentration of Credit Risk and Fair Value of Financial Instruments." Our repayment obligations are contingent upon future royalty revenue generated from the Madison Arrangement and there are no minimum or maximum payments under the arrangement.
Under ASC 470, amounts recorded as debt are amortized under the interest method. At each reporting period, we will review the discounted expected future cash flows over the life of the obligation. The Company made an accounting policy election to utilize the catch-up method when there is a change in the estimated future cash flows, whereby we will adjust the carrying amount of the debt to the present value of the revised estimated future cash flows, discounted at the original effective interest rate, with a corresponding adjustment recognized as interest expense within “Interest Expense” in the condensed consolidated statements of income. The effective interest rate as of the acquisition date was approximately 14.5%. This rate represents the discount rate that equates the estimated future cash flows with the fair value of the debt as of the acquisition date and is used to compute the amount of interest to be recognized each period based on the estimated life of the future revenue streams. During the three and nine months ended September 30, 2025, we recognized $0.6 million and $1.4 million, respectively, of interest expense related to this debt, compared to $0.6 million and $2.2 million during the three and nine months ended September 30, 2024, respectively. This was included within “Interest Expense” in the condensed consolidated statements of income. Any future payments made to CPPIB Credit, or additional proceeds received from CPPIB Credit, will decrease or increase the long-term debt balance accordingly. We made $1.3 million and $12.9 million in payments to CPPIB Credit during the nine months ended September 30, 2025 and 2024, respectively.

Technicolor Contingent Consideration
As part of the Technicolor Patent Acquisition, we entered into a revenue-sharing arrangement with Technicolor that created a contingent consideration liability. Under the revenue-sharing arrangement, Technicolor receives 42.5% of future cash receipts from new licensing efforts from the Madison Arrangement only, subject to certain conditions and hurdles. As of September 30, 2025, the contingent consideration liability from the revenue-sharing arrangement was deemed not probable and is therefore not reflected within the consolidated financial statements.
6. LITIGATION AND LEGAL PROCEEDINGS
ARBITRATIONS AND COURT PROCEEDINGS
Lenovo
In fourth quarter 2024, the Company reached an agreement with Lenovo Group Limited and certain of its subsidiaries (“Lenovo”) to enter into binding arbitration to determine the final terms of a new patent license agreement, which will be effective from January 1, 2024. In November 2024, the Company filed a request for arbitration with the International Chamber of Commerce. In March 2025, the International Chamber of Commerce confirmed the full tribunal for the arbitration.
Samsung
The Company reached an agreement with Samsung Electronics Co. Ltd. (“Samsung”) to enter into binding arbitration to determine the final terms of a renewed patent license agreement to certain of the Company’s patents, to be effective from January 1, 2023. The Company and Samsung also agreed not to initiate certain claims against the other during the arbitration. In March 2023, the Company filed a request for arbitration with the International Chamber of Commerce.
The arbitration hearing was held in July 2024, and closing arguments were held in October 2024. In July 2025, a panel of International Chamber of Commerce arbitrators determined the royalties of the patent license between the Company and Samsung covering Samsung’s products other than digital televisions and computer display monitors, which have been licensed under a separate agreement. The panel set the total royalties at $1.05 billion for the eight-year patent license.
Tesla
In December 2023, Tesla and certain of its subsidiaries filed a claim in the UK High Court against the Company and Avanci. The claim alleges invalidity of three of the Company’s patents relating to 5G standards: European Patent (UK) Nos. 3,718,369, 3,566,413, and 3,455,985. Tesla sought, among other relief, a declaration that the patents at issue are invalid, not essential, and not infringed, revocation of the patents at issue, a declaration that the terms of the Avanci 5G Connected Vehicle platform license are not FRAND, and a determination of FRAND terms for a license between Tesla and Avanci covering its Avanci’s 5G Connected Vehicle platform. In March 2024, the Company filed a jurisdiction challenge; the jurisdiction challenge was heard during May and June 2024, and in July 2024 the UK High Court issued a judgment dismissing Tesla’s FRAND claims against the Company and Avanci, and maintaining Tesla’s patent claims against the Company. The patent claims against the Company were further stayed by the UK High Court.
Tesla sought permission to appeal the decision; the Company also sought permission to appeal on two limited grounds conditionally, should Tesla’s request for an appeal be granted. The appeal hearing was held in December 2024, and the UK Court of Appeal upheld the lower court's decision and refused Tesla’s request for permission to appeal. Tesla filed an application for permission to appeal to the Supreme Court. In July 2025, the Supreme Court granted Tesla’s request for permission to appeal the issues of whether pool licenses are arguably required to be FRAND, whether all members of the Avanci 5G Platform must be joined to the case, and whether Tesla’s claim advances the possibility of a bilateral license from the Company. In September 2025, the Company filed an application for permission to cross-appeal.

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, 2025, except as noted above.
7. INCOME TAXES
In the nine months ended September 30, 2025 and 2024, the Company had an estimated effective tax rate of 13.3% and 18.4%, respectively. The change in effective tax rate is due to an increase in the amount of Foreign Derived Intangible Income ("FDII") deduction benefit available to the Company and tax benefits related to share-based compensation. In addition, the Company is subject to a decrease in the Global Intangible Low-Tax Income inclusion derived from the decrease in French revenue. During the nine months ended September 30, 2025 and 2024, the Company recorded discrete net benefits of $9.3 million and $4.3 million, respectively, primarily related to share-based compensation.
The One Big Beautiful Bill Act (the “Act”) was signed into law on July 4th, 2025. The Act contains significant tax law changes with various effective dates affecting business taxpayers. Among the tax law changes that will impact the Company relate to the timing and amount of certain tax deductions including FDII, depreciation expense, R&D expenditures and interest expense. The tax law changes did not have an impact on the tax provision in the third quarter of 2025.
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, 2025 and 2024, the Company paid approximately $78.6 million and $14.5 million, respectively, in foreign source creditable withholding tax.

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

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

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

9. SEGMENT PERFORMANCE MEASURES AND EXPENSES
Our chief operating decision maker (“CODM”), who is our Chief Executive Officer, assesses company-wide performance and allocates resources based on consolidated financial information. Consequently, we view the entire organization as one reportable segment and the strategic purpose of all operating activities is to support that one segment. Our CODM evaluates company-wide performance based on multiple performance measures, including, but not limited to, net income. Our CODM does not generally evaluate our performance using asset or historical cash flow information.
The table below provides the calculation of net income, which is the performance measure that is most consistent with GAAP, and the significant operating expenses included in this performance measure (in thousands):

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 2024 Form 10-K, other reports filed with the SEC and the Statement Pursuant to the Private Securities Litigation Reform Act of 1995 — Forward-Looking Statements below.
Throughout the following discussion and elsewhere in this Quarterly Report on Form 10-Q, we refer to “catch-up revenue.” For variable and dynamic fixed-fee license agreements, “catch-up revenue” primarily represents revenue associated with reporting periods prior to the execution of the license agreement.
New Agreements
During third quarter 2025, we signed four patent license agreements, including with Honor Device Co., Ltd. ("Honor"), a major Chinese smartphone vendor. We now have eight of the ten largest smartphone vendors and approximately 85% of the entire global smartphone market under license.
Disney Proceedings
In September 2025, we were awarded a preliminary injunction against Disney by a court in Brazil. The court ruled that we are entitled to a preliminary injunction over Disney’s infringement of two InterDigital patents related to AVC and HEVC video coding technology. The decision followed the publication of an independent expert report, commissioned by the Rio de Janeiro court, which fully supported our position that Disney infringed both of the patents-in-suit, and that InterDigital does not have a RAND obligation arising from the asserted encoder claims. The Appellate Court initially granted Disney’s request to stay the preliminary injunction pending hearing of an appeal, but that stay was lifted. Disney now has until November 30, 2025, to comply fully with the injunction.
For more information on the Disney proceedings, see Note 6, “Litigation and Legal Proceedings,” to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Deep Render Acquisition
In October, we acquired Deep Render, an AI startup with a team of world-class AI experts focusing on video codecs. We believe the acquisition adds significant depth to our existing AI expertise and strengthens the company’s leadership in video compression. The transaction also adds Deep Render’s patent portfolio in AI-based video coding to our market-leading video portfolio. As part of the deal, a team of AI experts will join our Video Lab.
Founded in London in 2018, Deep Render has pioneered the use of AI in video and image compression to change the way that video is processed and ultimately distributed to connected devices and services.
Return of Capital to Shareholders
In September 2025, we announced a second dividend increase during 2025, increasing the quarterly cash dividend by $0.10 per share to $0.70 per share, beginning with the quarterly dividend paid in fourth quarter 2025. Combined with previous increases, we have increased the dividend by 75% since the start of 2024. During third quarter 2025, we returned $53.3 million to shareholders, including $18.0 million, or $0.70 per share, of cash dividends declared and $35.3 million through the repurchase of shares of common stock.
As of October 30, 2025, there was $147.9 million remaining under the share repurchase authorization, which we plan to utilize to periodically repurchase additional common shares. See Part II, Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds—Issuer Purchases of Equity Securities of this Quarterly Report on Form 10-Q.
Cash & Short-term Investments
As of September 30, 2025, we had $1.3 billion of cash, restricted cash, and short-term investments and approximately $1.6 billion of cash payments due under contracted fixed price agreements, which includes our conservative estimates of the minimum cash receipts that we expect to receive under the Lenovo arbitration.
91% of our third quarter 2025 revenue is from fixed-fee agreements. Such agreements often have prescribed payment schedules that are uneven and sometimes front-loaded, resulting in timing differences between when we collect the cash payments and recognize the related revenue.

Table of Contents
The following table reconciles the timing differences between cash receipts and recognized revenue during the three and nine months ended September 30, 2025 and 2024, including the resulting operating cash flow (in thousands):

Net cash provided by operating activities$395,930 $77,631 $481,059 $79,494 
(a) Fixed fee cash receipts are comprised of cash receipts from Dynamic Fixed-Fee Agreement royalties, including the associated catch-up revenue.
(b) Other cash receipts are primarily comprised of cash receipts related to our variable patent royalty revenue and catch-up revenue.
When we collect payments on a front-loaded basis, we recognize a deferred revenue liability equal to the cash received and accounts receivable recorded which relate to revenue expected to be recognized in future periods. That liability is then reduced as we recognize revenue over the balance of the agreement. The following table shows the projected amortization of our current and long term deferred revenue as of September 30, 2025 (in thousands):

Total Revenue$411,913 
Revenue
Third quarter 2025 revenue of $164.7 million includes $17.7 million of catch-up revenue, while third quarter 2024 revenue of $128.7 million includes $30.0 million of catch-up revenue. The $36.0 million increase was primarily due to recurring revenue recognized from nine patent license agreements signed since third quarter 2024, partially offset by lower catch-up revenue in third quarter 2025. In third quarter 2025, revenue (in descending order) from Samsung, Apple, and Honor each comprised 10% or more of our consolidated revenue. Refer to "Results of Operations --Third Quarter 2025 Compared to Third Quarter 2024" for further discussion of our 2025 revenue.
Impact of Macroeconomic and Geopolitical Factors
We have been actively monitoring the impact of the current macroeconomic environment in the U.S. and globally characterized by market volatility, inflation, supply chain issues, high interest rates, tariffs and other potential trade-related sanctions, and the potential for a recession. These market factors, as well as the impacts of the Ukraine-Russia and Middle East conflicts, have not had a material impact on our business to date. However, if these conditions continue or worsen, they could have an adverse effect on our operating results and our financial condition.
Comparability of Financial Results
When comparing third quarter 2025 financial results against other periods, the following items should be taken into consideration:
Revenue
Our third quarter 2025 revenue includes $17.7 million of catch-up revenue primarily related to the new patent license agreement with Honor signed in third quarter 2025.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Our significant accounting policies are described in Note 2, "Summary of Significant Accounting Policies and New Accounting Guidance", in the notes to consolidated financial statements included in our 2024 Form 10-K. A discussion of our critical accounting policies, and the estimates related to them, are included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2024 Form 10-K. There have been no material changes to our existing critical accounting policies from the disclosures included in our 2024 Form 10-K. Refer to Note 1, “Basis of Presentation,” in the notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for updates related to new accounting pronouncements and changes in accounting policies.
FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES
Our primary sources of liquidity are cash, cash equivalents, and short-term investments, as well as cash generated from operations. We believe we have the ability to obtain additional liquidity through debt and equity financings. From time to time, we may engage in a variety of transactions to augment our liquidity position as our business dictates and to take advantage of favorable interest rate environments or other market conditions, including the incurrence or issuance of debt and the refinancing or restructuring of existing debt. Based on our past performance and current expectations, we believe our available sources of funds, including cash, cash equivalents, short-term investments, and cash generated from our operations, will be sufficient to finance our operations, capital requirements, debt obligations, existing stock repurchase program, dividend program, and other contractual obligations discussed below in both the short-term over the next twelve months, and the long-term beyond twelve months.
Cash, cash equivalents, restricted cash, and short-term investments
As of September 30, 2025 and December 31, 2024, we had the following amounts of cash and cash equivalents, restricted cash, and short-term investments (in thousands):
September 30, 2025December 31, 2024
Increase / (Decrease)
Cash and cash equivalents$840,270 $527,360 $312,910

Total cash, cash equivalents, restricted cash, and short-term investments
$1,271,498 $982,395 $289,103 
The net increase in cash, cash equivalents, restricted cash, and short-term investments was attributable to cash provided by operating activities of $481.1 million, partially offset by cash used in financing activities of $147.0 million and cash used in investing activities of $55.3 million, excluding sales and purchases of short-term investments. Refer to the sections below for further discussion of these items.
Cash flows provided by operating activities
Cash flows provided by operating activities in the first nine months 2025 and 2024 (in thousands) were as follows:

Net cash provided by operating activities$481,059 $79,494 $401,565 
24

Table of Contents
Our cash flows provided by operating activities are principally derived from cash receipts from patent license agreements, offset by cash operating expenses and income tax payments. The $401.6 million change in cash provided by operating activities was primarily driven by higher cash receipts from timing of cash receipts on existing agreements and new agreements, and was partially offset by higher foreign withholding tax payments on those cash receipts. Additionally, cash operating expenses were lower primarily due to lower revenue share and litigation costs. The table below sets forth the significant items comprising our cash flows provided by operating activities during the nine months ended September 30, 2025 and 2024 (in thousands):

______________________________
(a) Cash operating expenses include operating expenses less depreciation and disposals of fixed assets, amortization of patents, and non-cash compensation. Amount includes revenue share costs of $7.6 million and $78.7 million in first nine months 2025 and 2024, respectively.
(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 2025 was $36.9 million, a $176.3 million change from $139.4 million provided by investing activities in first nine months 2024. During first nine months 2025, we sold $18.3 million of short-term marketable securities, net of purchases, and capitalized $55.3 million of patent costs and property and equipment purchases. During first nine months 2024, we sold $173.2 million of short-term marketable securities, net of purchases, and capitalized $35.4 million of patent costs and property and equipment purchases.
Net cash used in financing activities for first nine months 2025 was $147.0 million, a change of $104.0 million from $251.0 million the first nine months 2024. This change was primarily attributable to a $126.2 million payment made on maturity of the 2024 Notes in first half 2024 and $7.3 million of proceeds from the exercise of stock options. This change was partially offset by a $28.9 million increase of taxes withheld on restricted stock unit vestings primarily due to the increased share price at vesting and a $12.2 million increase in dividends paid due to the announced increases in the declared dividend from $0.40 to $0.70.
Other
Our combined short-term and long-term deferred revenue balance as of September 30, 2025 was approximately $411.9 million, a net increase of $51.8 million from December 31, 2024. This increase in deferred revenue was primarily due cash receipts on new and existing patent license agreements, partially offset by amortization of deferred revenue recognized in the period.
Based on current license agreements, we expect the amortization of dynamic fixed-fee royalty payments to reduce the September 30, 2025 deferred revenue balance of $411.9 million by $234.5 million over the next twelve months.

Convertible Notes
See Note 5, “Obligations” to the Notes to condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for definitions of capitalized terms below.
From the period January 1, 2024 through December 31, 2025, the holders of the 2027 Notes have the right, but not the obligation, to convert any portion of the principal amount of the 2027 Notes.
Our 2027 Notes are included in the dilutive earnings per share calculation using the if-converted method. Under the if-converted method, we must assume that conversion of convertible securities occurs at the beginning of the reporting period. The 2027 Notes are convertible into cash up to the aggregate principal amount of the 2027 Notes to be converted and any remaining obligations may be settled in cash, shares of the Company’s common stock, or a combination thereof. As the principal amount must be paid in cash and only the conversion spread is settled in shares, we only include the net number of incremental shares that would be issued upon conversion. We must calculate the number of shares of our common stock issuable under the terms of the 2027 Notes based on the average market price of our common stock during the applicable reporting period and include that number in the total diluted shares figure for the period.
At the time we issued the 2027 Notes, we entered into the 2027 Call Spread Transactions that together were designed to have the economic effect of reducing the net number of shares that will be issued in the event of conversion of the 2027 Notes by, in effect, increasing the conversion price of the 2027 Notes from our economic standpoint. However, under GAAP, since the impact of the 2027 Note Hedge Transactions is anti-dilutive, we exclude from the calculation of fully diluted shares the number of shares of our common stock that we would receive from the counterparties to these agreements upon settlement.
During periods in which the average market price of our common stock is above the applicable conversion price of the 2027 Notes (initial conversion price of approximately $77.49 per share), or above the strike price of the warrants (weighted average strike price of $105.77 per share), the impact of conversion or exercise, as applicable, would be dilutive and such dilutive effect is reflected in diluted earnings per share. As a result, in periods where the average market price of our common stock is above the conversion price or strike price, as applicable, under the if-converted method, we calculate the number of shares issuable under the terms of the 2027 Notes and the 2027 Warrant Transactions 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.
26

Table of Contents
Under the if-converted method, changes in the price per share of our common stock can have a significant impact on the number of shares that we must include in the fully diluted earnings per share calculation. As described in Note 5, "Obligations," the 2027 Notes are convertible into cash up to the aggregate principal amount to be converted and any remaining obligations may be settled in cash, shares of the Company’s common stock or a combination thereof ("net share settlement"). Assuming net share settlement upon conversion, the following tables illustrate how, based on the $460.0 million aggregate principal amount of the 2027 Notes outstanding as of September 30, 2025, and the approximately 5.9 million warrants related to the 2027 Notes, changes in our stock price would affect (i) the number of shares issuable upon conversion of the 2027 Notes, (ii) the number of shares issuable upon exercise of the warrants subject to the 2027 Warrant Transactions, (iii) the number of additional shares deemed outstanding with respect to the 2027 Notes, after applying the if-converted method, for purposes of calculating diluted earnings per share ("Total If-Converted Method Incremental Shares"), (iv) the number of shares of our common stock deliverable to us upon settlement of the 2027 Note Hedge Transactions and (v) the number of shares issuable upon concurrent conversion of the 2027 Notes, exercise of the warrants subject to the 2027 Warrant Transactions, and settlement of the 2027 Note Hedge Transactions (in thousands):

(a)    Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.
Total revenue of $164.7 million increased $36.0 million from third quarter 2024 primarily due to revenue from nine new patent license agreements signed in the last twelve months, including the agreement signed with Honor in third quarter 2025 and the previously announced agreements with vivo Mobile and OPPO. Additionally, the Samsung arbitration decision contributed to the increase. These increases were partially offset by catch-up revenue recognized on new agreements and the resolution of litigation in third quarter 2024.
In third quarter 2025 and 2024, 54% and 83%, respectively, of our total revenue was attributable to licensees that individually accounted for 10% or more of our total revenue. In third quarter 2025 and 2024, the following licensees accounted for 10% or more of our total revenue:

Total change in operating expenses
$(463)
The $0.5 million decrease in operating expenses was due to a number of offsetting changes including a $4.6 million decrease in revenue share costs primarily related to catch-up revenue on agreements signed in third quarter 2024. Additionally, intellectual property enforcement costs, net decreased $2.4 million primarily due to resolutions of the OPPO, Lenovo UK, and Samsung matters, partially offset by increases related to the announced Disney proceedings and a $1.2 million one-time contra expense for a net litigation fee reimbursement resulting from intellectual property enforcement successes received in third quarter 2024.
Research and portfolio development expense: Research and portfolio development expense increased compared to third quarter 2024 primarily due to the costs associated with our growing patent portfolio and increased investment in the computer network that supports our research activities.
Licensing expense: Licensing expense decreased compared to third quarter 2024 primarily due to the above noted changes in revenue share and intellectual property enforcement costs, partially offset by the one-time net litigation fee reimbursement contra expense recognized in third quarter 2024.
General and administrative expense: General and administrative expense increased compared to third quarter 2024 primarily due to an increase in share-based compensation costs.

The change in non-operating income, net was primarily due to a foreign currency translation net loss arising from translation of our foreign subsidiaries of $0.6 million in third quarter 2025, compared to a $2.8 million net gain in third quarter 2024.
Income taxes
In third quarter 2025 and 2024, based on the statutory federal tax rate net of discrete federal and state taxes, we had an effective tax rate of 11.2% and 17.0%, 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 and tax benefits related to share-based compensation. In addition, the Company is subject to a decrease in the Global Intangible Low-Tax Income inclusion derived from the decrease in revenue in certain foreign jurisdictions.

(a)    Catch-up revenue represents revenue associated with reporting periods prior to the execution of the license agreement.
Total revenue of $675.8 million increased $60.1 million from first nine months 2024 primarily due to revenue from fifteen new patent license agreements signed in the last eighteen months, including the agreement signed with Honor in third quarter 2025 and the previously announced agreements with vivo Mobile, OPPO, Lenovo, and HP. Additionally, the Samsung arbitration ruling contributed to the increase. These increases were partially offset by catch-up revenue recognized in first nine months 2024 from the Samsung TV agreement, Lenovo UK ruling and arbitration agreement, and other new agreements signed during first nine months 2024.
In first nine months 2025 and 2024, 64% and 77% of our total revenue, respectively, was attributable to companies that individually accounted for 10% or more of our total revenue. In first nine months 2025 and 2024, the following companies accounted for 10% or more of our total revenue:

Table of Contents
Operating expenses decreased 22% to $262.7 million in first nine months 2025 from $338.7 million in first nine months 2024. The $76.0 million decrease in total operating expenses was primarily due to changes in the following items (in thousands):

Total change in operating expenses
$(76,010)
The $76.0 million decrease in operating expenses was driven by a $71.1 million decrease in revenue share costs primarily related to the Samsung TV and TPV agreements signed in first nine months 2024. Additionally, intellectual property enforcement costs decreased $22.4 million primarily due to resolutions of the OPPO, Lenovo UK, and Samsung matters, partially offset by increases related to the announced Disney proceedings. This decrease in intellectual property enforcement costs was partially offset by one-time contra expenses for net litigation fee reimbursements of $0.5 million in first nine months 2025 compared to $4.4 million in first nine months 2024 resulting from intellectual property enforcement successes.
These decreases were offset by a $5.3 million increase in depreciation and amortization due to non-cash patent acquisitions and investments in internal infrastructure and a $2.5 million increase in share-based compensation due to higher accrual rates driven by licensing successes.
Research and portfolio development expense: Research and portfolio development expense increased slightly compared to first nine months 2024 primarily due to the above noted increase in depreciation and amortization.
Licensing expense: Licensing expense decreased by $87.9 million compared to first nine months 2024 primarily driven by the above-noted decreased revenue share costs and intellectual property enforcement costs, partially offset by the one-time net litigation fee reimbursement.
General and administrative expense: General and administrative expense increased compared to first nine months 2024 primarily due to the above noted increases in share-based compensation and depreciation of internal infrastructure investments.

Total non-operating income (expense), net
$6,163 $(603)$6,766 1,122%
The change in non-operating income (expense), net was primarily due to a foreign currency translation net gain arising from translation of our foreign subsidiaries of $5.9 million in first nine months 2025, compared to a $0.5 million net loss in first nine months 2024.
Income Taxes
In first nine months 2025 and 2024, we had an effective tax rate of 13.3% and 18.4%, 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 and tax benefits related to share-based compensation. In addition, the Company is subject to a decrease in the Global Intangible Low-Tax Income inclusion derived from the decrease in revenue in certain foreign jurisdictions.

the failure of markets for our technologies to materialize to the extent that we expect;
our continued ability to develop new technologies;
changes in our interpretations of, and assumptions and calculations with respect to the impact on us of, the One Big Beautiful Bill Act, the 2017 Tax Cuts and Jobs Act and other U.S. and non-U.S. tax laws;
the timing and impact of potential regulatory, administrative and legislative matters;
the potential effects of macroeconomic conditions or trade conflicts;
our ability to hire and retain key personnel;

PART II — OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS.

See Note 6, “Litigation and Legal Proceedings,” to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for 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 2024 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 2024 Form 10-K. You should carefully consider such factors, which could materially affect our business, financial condition or future results. The risks described in the 2024 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.
Our business and operations may be adversely affected by a deterioration in United States-China relations or broader trade and geopolitical conditions.
The recent imposition of tariffs by the United States could materially harm our business. Companies headquartered in China currently comprise a substantial portion of customers that utilize our patented inventions in their devices and services. Our ability to renew license agreements with current licensees in China as well as license new manufacturers is, among other things, affected by the macroeconomic and geopolitical climate, as well as our business relationships and perceived reputation in China. The U.S. and Chinese governments are regularly engaged in various trade discussions, and in January 2020, the U.S. and China entered into Phase One of the Economic and Trade Agreement, which took steps to ease certain trade tensions between the U.S. and China, including tensions involving intellectual property theft and forced intellectual property transfers by China. Although the Phase One Trade Agreement was an encouraging sign of progress in the trade negotiations between the U.S. and China, the recent imposition of tariffs by the US government has increased tensions, both with China and globally.
Countermeasures imposed in response to such government actions could materially harm our business prospects, financial condition and cash flow. Currently, the future of existing tariffs, and the possibility for new tariffs or trade policies, remains uncertain. So far, these tariffs and trade policies have not had a significant impact on our ability to develop foundational technologies or to participate and lead open standard development, or our business operations or financial results more generally; however, there is no guarantee that we can avoid the impact of tariff and related economic effects in the future, and these trade measures and any retaliatory measures imposed could directly or indirectly harm our business. Our ability to renew or conclude new license agreements could also be affected by economic uncertainty, particularly in the handset market, in China or globally.
China is a key market for us, and any of these factors could harm our ability to execute our business plans. The ultimate impact of ongoing trade tensions is uncertain, but if tensions continue or escalate, we could suffer material harm to our business, financial condition and operating results.

EXHIBIT 10.1
InterDigital, Inc.
Amended and Restated Executive Severance and Change in Control Policy
This Amended and Restated Executive Severance and Change in Control Policy (the “Policy”) is designed to provide certain protections to a select group of key employees of InterDigital, Inc. (“InterDigital” or the “Company”) or any of its subsidiaries in connection with a change in control of InterDigital or if in connection with the involuntary termination of their employment under the circumstances described in this Policy. The Policy is designed to be an “employee welfare benefit plan” (as defined in Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), and this document is both the formal plan document and the required summary plan description for the Policy.
Effective Date: The effective date of this Amended and Restated Executive Severance and Change in Control Policy is October 5, 2025.
Term: This Amended and Restated Executive Severance and Change in Control Policy will have an initial term of one year commencing on the Effective Date (the “Initial Term”)On the first anniversary of the Effective Date and each anniversary thereafter, this Policy will renew automatically for additional one year terms (each an “Additional Term” and the then-current Initial Term or an Additional Term, as applicable, the “Term”), unless the Company provides each Eligible Employee written notice of non-renewal at least 30 days prior to the date of automatic renewal (such period of time, the “Renewal Deadline”). Notwithstanding the foregoing provisions, if (a) a Change in Control occurs when there are fewer than 12 months remaining during the Initial Term or an Additional Term, the term of this Policy will extend automatically through the date that is 12 months following the effective date of the Change in Control, or (b) if an initial occurrence of an act or omission by the Company constituting the grounds for Good Reason (as defined below) has occurred (the “Initial Grounds”), and the expiration date of the Cure Period (as defined below) with respect to such Initial Grounds could occur following the expiration of the Initial Term or an Additional Term, then the term of this Policy with respect to an Eligible Employee with Initial Grounds will extend automatically through the date that is 30 days following the expiration of such cure period, but such extension of the term shall only apply with respect to the Initial Grounds. If an Eligible Employee becomes entitled to benefits under this Policy during the term of this Policy, the Policy will not terminate until all of the obligations of the parties hereto with respect to this Policy have been satisfied. For clarity, an election by the Company not to renew this Policy for an Additional Term will not be deemed to be a termination of an Eligible Employee’s employment without Cause or grounds for a resignation for Good Reason and, accordingly, Eligible Employee will not be eligible for severance benefits set forth herein.
Eligible Employee: An individual is only eligible for protection under this Policy if he or she is an Eligible Employee and complies with its terms (including any terms in the employee’s Participation Agreement (as defined below)). To be an “Eligible Employee,” an employee must (a) have been designated by the Human Capital Committee of the Board (the “Human Capital Committee”) as eligible to participate in the Policy, (b) have executed on or before the date specified in writing by the Company, both (i) a participation agreement in the form attached hereto as Exhibit A (a “Participation Agreement”) and (ii) InterDigital’s Executive Mutual Agreement for Individual Arbitration in the form attached hereto as Exhibit B. For purposes of clarity, Eligible Employees prior to the Effective Date of this Amended and Restated Executive Severance and Change in Control Policy are no longer Eligible Employees unless they meet all of the requirements set forth above.
Policy Benefits: An Eligible Employee will be eligible to receive the payments and benefits set forth in this Policy and his or her Participation Agreement if his or her employment with the Company or any of its subsidiaries terminates as a result of a Qualified Termination. The amount and terms of any Equity Vesting, Salary Severance, Bonus Severance, COBRA Payment, and Outplacement Services that an Eligible Employee may receive on his or her Qualified Termination will depend on whether his or her Qualified Termination is a COC Qualified Termination or a Non-COC Qualified Termination. All benefits under this Policy payable on a Qualified Termination will be subject to the Eligible Employee’s compliance with the Release Requirement and any timing modifications required to avoid adverse taxation under Section 409A.
Executive Mutual Arbitration Agreement – Rev 9/4/2025


Equity Vesting: An Eligible Employee’s acceleration of vesting of Company equity awards upon a Qualified Termination or otherwise will continue to be governed by the Eligible Employee’s equity award agreements (each such agreement, an “Equity Award Agreement”) under the applicable Company equity incentive plan (each, a “Plan”).
Salary Severance: On a Qualified Termination, an Eligible Employee will be eligible to receive salary severance payment(s) equal to the applicable percentage (set forth in his or her Participation Agreement) of his or her Base Salary (“Salary Severance”). The Eligible Employee’s salary severance payment(s) will be paid in cash at the time(s) specified in his or her Participation Agreement.
Bonus Severance: On a Qualified Termination, an Eligible Employee will be eligible to receive bonus severance payment(s) with respect to any annual bonus set forth in his or her Participation Agreement in the applicable percentage set forth in his or her Participation Agreement (“Bonus Severance”). The Eligible Employee’s Bonus Severance payment(s) will be paid in cash at the time(s) specified in his or her Participation Agreement.
COBRA Payment: Upon a Qualified Termination, the Company will either (i) pay, on behalf of Eligible Employee, the cost of COBRA continuation coverage for the Eligible Employee and any eligible dependents there were covered under the Company’s health care plans immediately prior to the date of his or her Qualified Termination for the applicable period set forth in the Eligible Employees’ Participation Agreement or (ii) pay the Eligible Employee a lump-sum cash payment equal to 1.5 times of the cost of COBRA continuation coverage for the Eligible Employee and any eligible dependents that were covered under the Company’s health care plans immediately prior to the date of his or her eligible Qualified Termination through the end of the applicable period set forth in the Eligible Employee’s Participation Agreement.
Outplacement Services: On a Qualified Termination, an Eligible Employee will be eligible to receive reasonable outplacement services in accordance with any applicable Company policy in effect as of the Qualified Termination (or if no such policy is in effect, as determined by the Company, in its sole discretion, provided that such outplacement services are provided by qualified consultants selected by the Company, at the Company’s expense, in an amount not to exceed $10,000) (“Outplacement Services”).
Death of Eligible Employee: If the Eligible Employee dies before all payments or benefits he or she is entitled to receive under this Policy have been paid, such unpaid amounts will be paid to his or her designated beneficiary, if living, or otherwise to his or her personal representative in a lump-sum payment as soon as possible following his or her death.
Recoupment: If the Company discovers after the Eligible Employee’s receipt of payments or benefits under this Policy that grounds for the termination of the Eligible Employee’s employment for Cause existed, then the Eligible Employee will not receive any further payments or benefits under this Policy and, to the extent permitted under applicable laws, will be required to repay to the Company any payments or benefits he or she received under the Policy (or any financial gain derived from such payments or benefits).
- 2 -


Release: The Eligible Employee’s receipt of any severance payments or benefits upon his or her Qualified Termination under this Policy is subject to (i) the Eligible Employee’s continued compliance with the terms of his or her Nondisclosure and Assignment of Ideas Agreement (the “Covenants Agreement”), and (ii) the Eligible Employee signing and not revoking the Company’s then-standard separation agreement and release of claims (which may include an agreement not to disparage the Company, non-solicit provisions, and other standard restrictive covenants, terms and conditions) (the “Release” and such requirement, the “Release Requirement”), which must become effective and irrevocable no later than the 60th day following the Eligible Employee’s Qualified Termination (the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, the Eligible Employee will forfeit any right to severance payments or benefits under this Policy. In no event will severance payments or benefits under the Policy be paid or provided until the Release actually becomes effective and irrevocable. Notwithstanding any other payment schedule set forth in this Policy or the Eligible Employee’s Participation Agreement, none of the severance payments and benefits payable upon such Eligible Employee’s Qualified Termination under this Policy will be paid or otherwise provided prior to the 60th day following the Eligible Employee’s Qualified Termination. Except as otherwise set forth in an Eligible Employee’s Participation Agreement or to the extent that payments are delayed under the paragraph below entitled “Section 409A,” on the first regular payroll pay day following the 60th day following the Eligible Employee’s Qualified Termination, the Company will pay or commence to pay the Eligible Employee the severance payments and benefits that the Eligible Employee would otherwise have received under this Policy on or prior to such date, with the balance of such severance payments and benefits being paid or provided as originally scheduled. Any installment payments that would have been made to an Eligible Employee during the 60 day period immediately following an Eligible Employee’s separation from service but for the preceding sentence will be paid to an Eligible Employee on the first Company payroll following the Release Deadline and the remaining payments will be made as provided in this Policy.
Section 409A: The Company intends that all payments and benefits provided under this Policy or otherwise are exempt from, or comply with, the requirements of Section 409A of the Code and any guidance promulgated thereunder (collectively, “Section 409A”) so that none of the payments or benefits will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted in accordance with this intent. No payment or benefits to be paid to an Eligible Employee, if any, under this Policy or otherwise, when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A (together, the “Deferred Payments”) will be paid or otherwise provided until such Eligible Employee has a “separation from service” within the meaning of Section 409A. If, at the time of the Eligible Employee’s termination of employment, the Eligible Employee is a “specified employee” within the meaning of Section 409A, then the payment of the Deferred Payments will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under Section 409A, which generally means that the Eligible Employee will receive payment on the first payroll date that occurs on or after the date that is 6 months and 1 day following his or her termination of employment. The Company reserves the right to amend the Policy as it deems necessary or advisable, in its sole discretion and without the consent of any Eligible Employee or any other individual, to comply with any provision required to avoid the imposition of the additional tax imposed under Section 409A or to otherwise avoid income recognition under Section 409A prior to the actual payment of any benefits or imposition of any additional tax. Each payment, installment, and benefit payable under this Policy is intended to constitute a separate payment for purposes of U.S. Treasury Regulation Section 1.409A-2(b)(2). In no event will the Company reimburse any Eligible Employee for any taxes that may be imposed on him or her as a result of Section 409A.
- 3 -


Parachute Payments:
Reduction of Severance Benefits. Notwithstanding anything set forth herein to the contrary, if any payment or benefit that an Eligible Employee would receive from the Company or any other party whether in connection with the provisions herein or otherwise (the “Payment”) would (a) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (b) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Best Results Amount. The “Best Results Amount” will be either (x) the full amount of such Payment or (y) such lesser amount as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes and the Excise Tax, results in the Eligible Employee’s receipt, on an after-tax basis, of the greater amount notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting parachute payments is necessary so that the Payment equals the Best Results Amount, reduction will occur in the following order: reduction of cash payments; cancellation of accelerated vesting of stock awards; reduction of employee benefits. In the event that acceleration of vesting of stock award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of the Eligible Employee’s equity awards unless the Eligible Employee elects in writing a different order for cancellation. The Eligible Employee will be solely responsible for the payment of all personal tax liability that is incurred as a result of the payments and benefits received under this Policy, and the Eligible Employee will not be reimbursed by the Company for any such payments.
Determination of Excise Tax Liability. The Company will select a professional services firm to make all of the determinations required to be made under these paragraphs relating to parachute payments. The Company will request that firm provide detailed supporting calculations both to the Company and the Eligible Employee prior to the date on which the event that triggers the Payment occurs if administratively feasible, or subsequent to such date if events occur that result in parachute payments to the Eligible Employee at that time. For purposes of making the calculations required under these paragraphs relating to parachute payments, the firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith determinations concerning the application of the Code. The Company and the Eligible Employee will furnish to the firm such information and documents as the firm may reasonably request in order to make a determination under these paragraphs relating to parachute payments. The Company will bear all costs the firm may reasonably incur in connection with any calculations contemplated by these paragraphs relating to parachute payments. Any such determination by the firm will be binding upon the Company and the Eligible Employee, and the Company will have no liability to the Eligible Employee for the determinations of the firm.
Administration: The Policy will be administered by the Human Capital Committee or its delegate (in each case, a “Plan Administrator”). The Plan Administrator will have full discretion to administer and interpret the Policy. Any decision made or other action taken by the Plan Administrator with respect to the Policy and any interpretation by the Plan Administrator of any term or condition of the Policy, or any related document, will be conclusive and binding on all persons and be given the maximum possible deference allowed by law. The Plan Administrator is the “plan administrator” of the Policy for purposes of ERISA and will be subject to the fiduciary standards of ERISA when acting in such capacity.
Attorneys Fees: The Company and each Eligible Employee will bear their own attorneys’ fees incurred in connection with any disputes between them.
Exclusive Benefits: Except as may be set forth in an Eligible Employee’s Participation Agreement, this Policy is intended to be the only agreement between the Eligible Employee and the Company regarding any change in control or severance payments or benefits (other than any acceleration of equity which shall continue to be governed by the Equity Award Agreements) to be paid to the Eligible Employee on account of a termination of employment whether unrelated to, concurrent with, or following, a Change in Control. Accordingly, by executing a Participation Agreement, an Eligible Employee hereby forfeits and waives any rights to any severance or change in control benefits set forth in any employment agreement, offer letter, and/or the Company’s Severance Pay Plan, except as set forth in this Policy, the Eligible Employee’s Participation Agreement and the Equity Award Agreements.
- 4 -


Tax Withholding: All payments and benefits under this Policy will be paid less applicable withholding taxes. The Company or the subsidiary employing the Eligible Employee, as applicable, is authorized to withhold from any payments or benefits all federal, state, local and/or non-U.S. taxes required to be withheld therefrom and any other required payroll deductions. The Company or the subsidiary employing the Eligible Employee, as applicable, will not pay, reimburse Eligible Employee for, or be liable or responsible for any of Eligible Employee’s taxes arising from or relating to any payments or benefits under this Policy; instead, any such taxes will be solely the responsibility of Eligible Employee.
Amendment or Termination: The Human Capital Committee may amend or terminate the Policy at any time, without advance notice to any Eligible Employee or other individual and without regard to the effect of the amendment or termination on any Eligible Employee or on any other individual. Notwithstanding the preceding, no amendment or termination of the Policy will be made if such amendment or termination would reduce the benefits provided hereunder or impair an Eligible Employee’s eligibility under the Policy (unless the affected Eligible Employee consents to such amendment or termination), except that the Human Capital Committee may unilaterally and without consent of any Eligible Employee make any such amendments that are necessary or appropriate to comply with applicable laws. For clarity, an action by the Plan Administrator not to renew the Policy in accordance with the Term provision above will not be an action that requires an Eligible Employee’s consent. Further, an action to amend the Policy in a given Term that is effective as of the commencement of an Additional Term will not be an action that requires an Eligible Employee’s consent. Any action to amend or terminate the Policy will be taken in a non-fiduciary capacity.
Claims Procedure: Any Eligible Employee who believes he or she is entitled to any payment under the Policy may submit a claim in writing to the Plan Administrator. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Policy on which the denial is based. The notice will also describe any additional information needed to support the claim and the Policy’s procedures for appealing the denial. The denial notice will be provided within 90 days after the claim is received. If special circumstances require an extension of time (up to 90 days), written notice of the extension will be given within the initial 90-day period. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision on the claim.
Appeal Procedure: If the claimant’s claim is denied, the claimant (or his or her authorized representative) may apply in writing to the Plan Administrator for a review of the decision denying the claim. Review must be requested within 60 days following the date the claimant received the written notice of their claim denial or else the claimant loses the right to review. The claimant (or representative) then has the right to review and obtain copies of all documents and other information relevant to the claim, upon request and at no charge, and to submit issues and comments in writing. The Plan Administrator will provide written notice of the decision on review within 60 days after it receives a review request. If additional time (up to 60 days) is needed to review the request, the claimant (or representative) will be given written notice of the reason for the delay. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Plan Administrator expects to render its decision. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Policy on which the denial is based. The notice will also include a statement that the claimant will be provided, upon request and free of charge, reasonable access to, and copies of, all documents and other information relevant to the claim and a statement regarding the claimant’s right to bring an action under Section 502(a) of ERISA.
Successors: Any successor to the Company of all or substantially all of the Company’s business and/or assets (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or other transaction) will assume the obligations under the Policy and agree expressly to perform the obligations under the Policy in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under the Policy, the term “Company” will include any successor to the Company’s business and/or assets which becomes bound by the terms of the Policy by operation of law, or otherwise.
Applicable Law: The provisions of the Policy will be construed, administered, and enforced in accordance with ERISA and, to the extent applicable, the internal substantive laws of the state of Delaware (but not its conflict of laws provisions).

If the Eligible Employee does not terminate his or her employment for Good Reason within sixty (60) days following the end of such sixty (60) day period within which the Company was entitled to remedy the course of conduct constituting Good Reason but failed to do so, then the Eligible Employee shall be deemed to have waived his or her right to terminate for Good Reason with respect to such grounds.

Statement of ERISA Rights:
Eligible Employees have certain rights and protections under ERISA:
They may examine (without charge) all Policy documents, including any amendments and copies of all documents filed with the U.S. Department of Labor, such as the Policy’s annual report (Internal Revenue Service Form 5500). These documents are available for review in the Company’s Human Resources Department.
They may obtain copies of all Policy documents and other Policy information upon written request to the Plan Administrator. A reasonable charge may be made for such copies.
In addition to creating rights for Eligible Employees, ERISA imposes duties upon the people who are responsible for the operation of the Policy. The people who operate the Policy (called “fiduciaries”) have a duty to do so prudently and in the interests of Eligible Employees. No one, including the Company or any other person, may fire or otherwise discriminate against an Eligible Employee in any way to prevent them from obtaining a benefit under the Policy or exercising rights under ERISA. If an Eligible Employee’s claim for a severance benefit is denied, in whole or in part, they must receive a written explanation of the reason for the denial. An Eligible Employee has the right to have the denial of their claim reviewed. (The claim review procedure is explained above.)
Under ERISA, there are steps Eligible Employees can take to enforce the above rights. For instance, if an Eligible Employee requests materials and does not receive them within 30 days, they may file suit in a federal court. In such a case, the court may require the Plan Administrator to provide the materials and to pay the Eligible Employee up to $147 a day until they receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. If an Eligible Employee has a claim which is denied or ignored, in whole or in part, he or she may file suit in a state or federal court. If it should happen that an Eligible Employee is discriminated against for asserting their rights, he or she may seek assistance from the U.S. Department of Labor, or may file suit in a federal court.
In any case, the court will decide who will pay court costs and legal fees. If the Eligible Employee is successful, the court may order the person sued to pay these costs and fees. If the Eligible Employee loses, the court may order the Eligible Employee to pay these costs and fees, for example, if it finds that the claim is frivolous.
If an Eligible Employee has any questions regarding the Policy, please contact the Plan Administrator. If an Eligible Employee has any questions about this statement or about their rights under ERISA, they may contact the nearest area office of the Employee Benefits Security Administration (formerly the Pension and Welfare Benefits Administration), U.S. Department of Labor, listed in the telephone directory, or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue, N.W. Washington, D.C. 20210. An Eligible Employee may also obtain certain publications about their rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

EXHIBIT 10.2
Exhibit B
EXECUTIVE MUTUAL AGREEMENT FOR INDIVIDUAL ARBITRATION
The undersigned individual (“You” or “Your”) and InterDigital, Inc. and/or InterDigital Communications, Inc. and/or InterDigital Holdings, Inc. (all and singularly, the “Company (collectively referred to as the “Parties” and any and each of whom may be referred to as a “Party”) knowingly enter into this Mutual Agreement for Individual Arbitration (“Agreement”).
You and the Company recognize that disputes may arise before, during, or following Your employment with the Company. You and the Company wish to resolve those disputes in an efficient and economical manner. You and the Company agree and acknowledge that any and all disputes between You and the Company that may arise out of or be related in any way to your application for employment, employment, termination of employment and/or this Agreement will be submitted and resolved exclusively through binding individual arbitration, other than the Excluded Claims (defined below). You and the Company acknowledge and agree that You and the Company are each giving up the right to a trial before a judge or a jury or to participate in any class, collective, or representative action. You and the Company both understand that arbitration is an alternative method of resolving disputes outside of court and that the arbitrator’s decision is final and binding. You and the Company further understand and agree that this Agreement and the arbitration will be subject to the following terms:
1.Definitions Used in This Agreement
a.Covered Claimsmeans any and all employment-related claims, disputes, actions, lawsuits or controversies (“Claims”), including but not limited to all claims, disputes, or controversies arising out of or relating to Your application or candidacy for employment, employment and/or cessation of employment with the Company (other than Excluded Claims as defined below). This includes Claims that the Company may have against You or that You may have against the Company, and any and all direct or indirect parent, subsidiary or affiliated companies, and any of their officers, directors, managers, employees, benefit administrators, successors, assigns, clients, or alleged joint employers relating in any way to your employment or cessation of employment (each an “Affiliate” and collectively the “Affiliates”). Covered Claims include claims arising before the execution of this Agreement that are brought after this Agreement is signed.
Examples of Covered Claims that must be arbitrated, by way of example only, include: claims under federal, state and/or local statutes regarding the payment of wages, overtime, severance pay, benefits, bonuses, commissions and/or other compensation of any kind; any claims of discrimination based on age, sex, pregnancy, race, religion, color, creed, disability, handicap, failure to accommodate, citizenship, marital status, national origin, ancestry, sexual orientation, gender identity, genetic information, or any other factor protected by federal, state or local statutes prohibiting employment discrimination, including any claims for retaliation and/or harassment under these or any other laws (but not the Excluded Claims); and any other claims arising out of or relating to Your application for employment, employment and/or cessation of employment under federal, state and/or local statutes, ordinances, constitutions and/or common law including, but not limited to, claims for retaliation and/or whistleblower claims, claims for wrongful discharge or discharge in violation of public policy, misrepresentation, breach of contract, invasion of privacy, or intentional/negligent torts including but not limited to infliction of emotional distress or defamation.
b.Excluded Claimsmeans all and singularly, Governmental Insurance Claims, Regulatory Complaints, and Sexual Harassment and Assault Disputes, and Unfair Competition Claims (each as defined below).
Executive Mutual Arbitration Agreement – Rev 9/4/2025


i.Governmental Insurance Claims” means claims for payment of state or local employment-related insurance (e.g., unemployment compensation, workers’ compensation, or worker disability compensation) filed with the applicable federal, state or local regulatory agencies or authorities. Statutory or common law claims alleging that the Company retaliated or discriminated against You for filing a federal state or local employment-related insurance claim or engaging in other protected conduct, however, are not Governmental Insurance Claims.
ii.Regulatory Complaints” means administrative charges or complaints filed with the National Labor Relations Board, Department of Labor, Equal Employment Opportunity Commission, Occupational Safety and Health Administration, or similar federal, state or local regulatory agencies or authorities, but not lawsuits filed in court based upon or related to administrative charges or complaints.
iii.Sexual Harassment and Assault Disputesmeans sexual harassment disputes and sexual assault disputes, as those terms are defined in the Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act of 2021.
iv.Unfair Competition Claimsmeans (1) claims to interpret, apply, or enforce the confidentiality, proprietary information, trade secret, intellectual property, nonsolicitation, noninterference, noncompetition, or other restrictive covenant provisions in any agreement between You and either the Company or any Affiliate, including but not limited to your Non- Disclosure and Assignment of Ideas Agreement; (2) common-law or statutory claims regarding (i) the possession, use, misappropriation, dissemination, actual or inevitable disclosure of, or reliance on information alleged to be confidential, proprietary, and/or trade secret, (ii) unfair competition, or (iii) tortious interference with contractual, business, or employment relationships; and (3) claims for declaratory, injunctive, or other equitable relief related to any of the claims listed in (1) or (2).
2.Agreement to Arbitrate Covered Claims. You and the Company agree to resolve any and all Covered Claims through final and binding arbitration, before a single neutral arbitrator, pursuant to the Federal Arbitration Act (“FAA”), administered by the American Arbitration Association (the “AAA”). To the extent not otherwise provided in this Agreement, the arbitration shall be pursuant to and in accordance the AAA Employment Arbitration Rules and Mediation Procedures as then in effect (“AAA Rules”). In the event of a conflict between this Agreement and the AAA Rules, this Agreement shall govern. The AAA Rules can be obtained online at www.adr.org or upon request to the Company. You and the Company voluntarily waive all rights to trial in court before a judge or a jury on all Covered Claims.
3.Claims Not Covered by This Agreement. You and the Company are not required to arbitrate the Excluded Claims (defined above). You understand that you still may file administrative charges or complaints with or provide information to the National Labor Relations Board, the Department of Labor, Equal Employment Opportunity Commission, Occupational Safety and Health Administration, Securities and Exchange Commission or other similar federal, state or local agencies or entities, but that upon receipt of a right to sue letter or similar administrative determination, You shall arbitrate any claim that You have against the Company. You understand and agree that to the maximum extent permitted by law, You are precluded from receiving any monetary or other relief obtained by any federal, state, or local agency on Your behalf, in any suit brought in any court against the Company. Notwithstanding the foregoing, nothing in this Agreement limits Your right to receive an award for information provided to the Securities and Exchange Commission, Department of Labor or any other government agency or government entity.
4.Class Action, Collective Action, And Representative Action Waiver. If there is more than one Claim between the Company and You, all such claims will be heard in a single proceeding. There shall be no right or authority for any Claims subject to arbitration under this Agreement to be arbitrated on a class, collective or representative action basis. Claims between the Company and other employees will each be heard in separate proceedings. You hereby waive any right to participate, in any manner, in a class, collective, mass or representative action (“Class Action Waiver”).
- 2 -


5.Issues to be Determined by a Court. All gateway arbitration issues, including the validity, enforceability, and scope of the obligation to arbitrate under this Agreement shall be decided by a court of competent jurisdiction and not an arbitrator, including but not limited to whether a claim or dispute is arbitrable. For example, any dispute as to the enforceability of the Class Action Waiver, whether the claims or disputes of one employee may be consolidated with the claims or disputes of others, or whether a claim is a Covered Claim or an Excluded Claim, shall be determined by court of competent jurisdiction and not by the arbitrator. In the event a court determines that the Class Action Waiver is unenforceable with respect to any Claim, then this waiver shall not apply to that Claim, and that Claim must be filed in a court of competent jurisdiction, and that court shall be the exclusive forum for that Claim. In the event of any conflict between this Section 5 and any other section or provision of this Agreement, this Section 5 shall govern.
6.Law Governing Agreement. This Agreement is covered by and made pursuant to the Federal Arbitration Act (the “FAA”), 9 U.S.C. § 1 et seq., and shall be construed, interpreted, governed, and enforced in accordance with the FAA. A court may not decline to enforce this Agreement on the ground that a party to the Agreement also is a party to a pending court action or special proceeding with a third party arising out of the same transaction or series of related transactions, or on the ground that the arbitration may produce a result that may conflict with the outcome of related litigation not subject to this Agreement.
7.Consent of the Parties. This Agreement shall be construed in accordance with the FAA and shall not be construed against the drafter. This Agreement reflects the mutual consent and agreement of You and the Company to the individualized arbitration of Covered Claims consistent with the FAA.
8.Arbitration Procedures. The arbitrator shall be selected by mutual agreement of both You and the Company or in accordance with AAA Rules. The Arbitrator shall have the power to award any type of legal or equitable relief available in a court of competent jurisdiction. If You initiate any Claims, Your portion of the AAA filing fee shall not exceed $350.00. The Company will pay the remainder of the filing fee, the arbitrator’s fee and any AAA administrative expenses. Any demand for arbitration must include the following information: (a) identify the party requesting arbitration by name, address, and telephone number; (b) a description of the facts upon which the Claim is based, the persons involved, the date and location of any occurrences giving rise to the Claim, and the law(s) allegedly violated; and (c) a description of the remedy requested. The Parties shall be entitled to engage in reasonable discovery. The arbitration shall take place in the county in which You regularly perform(ed) Your work for the Company. The arbitrator will apply whatever statute of limitations would be applicable to the Claim if it were filed in court. Each party shall pay its own costs and attorneys’ fees, if any. However, in the event that arbitration is brought pursuant to any law or statute which provides for awarding attorneys’ fees and costs, the arbitrator shall have the authority to award costs and/or attorneys’ fees pursuant to the applicable law or statute. Any dispute as to the reasonableness of any fee or cost shall be resolved by the arbitrator.
9.Arbitrator’s Decision. The arbitrator shall issue a written reasoned award, setting forth the essential findings and conclusions upon which the arbitrator based the award. The award shall be final and binding upon the parties. Any award may be entered as judgment in any court of competent jurisdiction.
10.Retained Rights. Nothing in this Agreement is intended to or shall be interpreted to restrict or otherwise interfere with Your right to: (1) testify truthfully in any forum; (2) provide information to, file a charge or complaint with, testify, or otherwise participate in any action, investigation or proceeding of, any federal, state, or local government agency, commission or entity (including, but not limited to, the Equal Employment Opportunity Commission; (3) disclose any information or produce any documents as is required by law, regulation or legal process; (4) report any conduct you believe to be criminal or unlawful to any appropriate federal, State, or local official; or (5) request or receive confidential legal advice.
11.Third-Party Enforcement. Any customer or Affiliate of the Company is a third-party beneficiary under this Agreement for purposes of being able to enforce this Agreement with regard to any claims between You and such customer or Affiliate of the Company, and such customer or Affiliate may enforce this Agreement to the maximum extent permissible by law or equity, pursuant to any one or combination of legal or equitable theories including, but not limited to, agency, equitable estoppel, and/or third party beneficiary, as applicable.

12.Severability. If any provision of this Agreement, or any portion thereof, is adjudged or declared by an arbitrator or a court of competent jurisdiction to be illegal, void, or otherwise unenforceable, in whole or in part, such adjudication shall not affect the validity of the remainder of the Agreement, which shall continue in full force and effect without said provision(s) or portion of said provision(s), insofar as they are consistent with existing applicable law, except to the extent otherwise provided in Section 5 regarding the Class Action Waiver. In other words, in the event a court determines that the Class Action Waiver is illegal, void, or otherwise unenforceable with respect to any Claim, then this waiver shall not apply to that Claim, and that Claim must be filed in a court of competent jurisdiction, and that court shall be the exclusive forum for that Claim.
13.Requirements for Modification or Revocation. This Agreement shall survive the termination of Your employment with the Company. It can only be revoked or modified by a writing signed by both You and the Company’s Chief People Officer or Chief Legal Officer that specifically states the intent to revoke or modify this Agreement.
14.At Will Employment. Nothing in this Agreement shall modify or change Your status as an at-will employee. Your employment shall be for no specific term and can be terminated by either You or the Company at any time, with or without cause or advance notice.
15.Sole and Entire Agreement. This is the complete and entire agreement of the Parties on the subject of arbitration of disputes. This Agreement supersedes any prior or contemporaneous oral or written understanding on the subject. The Parties agree that the Agreement supersedes any and all prior agreements, if any, on the subject of arbitration of disputes. No Party is relying on any representations, oral or written, on the subject of the effect, enforceability, or meaning of this Agreement, except as specifically set forth in this Agreement.
16.Consideration. You and the Company are each agreeing to arbitrate Covered Claims, and this mutual agreement to arbitrate constitutes good and sufficient consideration to support the mutual promises made by You and the Company. You further agree and acknowledge that you may not be covered by or potentially eligible for benefits under the Company’s Amended and Restated Executive Severance and Change in Control Policy, unless you enter into this Agreement. Additionally, the Company’s agreement to pay any portion of Your AAA filing fee in excess of $350.00, the arbitrator’s fee and any AAA administrative expenses associated with the arbitration, provides additional consideration which, by itself, is sufficient to support Your binding agreement to submit Covered Claims to arbitration.
17.Format of Signatures. This Agreement may be signed in counterparts and a PDF, facsimile, or electronic copy of an original ink signature shall have the same force and effect as the original. This Agreement may also be signed via DocuSign, which the Parties agree shall have the same force and effect as an ink signature. The Company may execute this Agreement with a stamped or printed signature, which stamped or printed signature shall be legally binding upon the Company.
