2025 Compensation Decisions and Actions
The following are highlights of the key compensation decisions made by the Human Capital Committee for 2025:
•Provided a majority of our executives’ target compensation in equity to align our executives’ interests with those of our shareholders. Approximately 82% of our CEO’s 2025 target compensation and, on average, 76% of 2025 target compensation for our other NEOs was in equity incentives, with approximately 67% of our CEO’s and 50% of our other NEOs’ 2025 equity in the form of performance-based equity awards.
•Paid Short Term Incentive Program (“STIP”) awards out at 178% of target based on performance results, including revenue of $834 million, the second highest in the company's history, and continued growth of our patent portfolio by 14% year over year.
•Based on shareholder feedback, designed our 2025 Long Term Compensation Program's ("LTCP") performance-based equity to be based on average pro forma EBITDA over the full three-year period rather than the highest four quarters during the performance period. Pro forma EBITDA is a supplemental non-GAAP financial measure that InterDigital believes provides investors with important insight into our ongoing business performance. Additional information can be found in Appendix A.
•Amended our stock ownership guidelines to be more rigorous by increasing our CEO's target ownership level from 5x to 6x his annual salary.
Shareholder Engagement and Results from 2025 Shareholder Advisory Vote on Executive Compensation
At the 2025 annual meeting of shareholders, we held an advisory vote on executive compensation. In 2025, we received shareholder support for our executive compensation programs with say on pay support of approximately 96%. The Human Capital Committee considers the results of the annual advisory vote on executive compensation as an important data point in its compensation decisions.
The Human Capital Committee actively and directly seeks out feedback from shareholders regarding the executive compensation program. Specifically, in the fall of 2025, the Chair of the Human Capital Committee, our investor relations team, and as appropriate, members of senior management, reached out to 25 of our largest investors, which collectively own about 70% of our outstanding shares, and ultimately engaged with certain of these investors to discuss and receive input, including about our executive compensation.
In addition, during fiscal year 2025, our investor relations team participated in sixteen investor conferences and seven non-deal roadshow events and engaged with existing and prospective institutional investors in over 200 meetings to keep an open dialog about our business and performance. Our investor relations team discusses with our shareholders any subject they wish to raise, subject to the limitations of applicable securities law, including financial activities, strategy, sustainability and executive compensation.
Good Governance Practices and Policies
The Human Capital Committee and the company strive to maintain good governance practices and regularly review and update such practices related to the compensation of our executives, including our NEOs. The following table highlights the responsible practices we have implemented, as well as the practices we have avoided, in order to best serve our shareholders’ long-term interests:
| | | | | |
| WHAT WE DO | WHAT WE DO NOT DO |
✓ We incorporate shareholder feedback into our compensation program design. | ☒ We do not have single-trigger payout provisions in our equity award agreements. |
✓ We create a balanced compensation program through a mix of fixed and variable short- and long-term incentives. |
✓ We cap payouts under our annual STIP to individual employees, including our NEOs, at two times target. | ☒ We do not provide golden parachute tax gross-ups. |
✓ We have double-trigger change in control payout provisions (i.e., an executive must be terminated in connection with a change in control in order to receive any change in control benefits). |
✓ We maintain a clawback policy that allows for recoupment of excess incentive compensation paid to our executive officers in the event of certain accounting restatements. | ☒ We do not provide excessive perquisites to executives that other employees at or above the senior director level do not receive. |
✓ We have robust target stock ownership levels for our executive officers and directors, defining qualifying stock to include only shares of common stock or vested RSUs held outright or indirectly through the 401k. | ☒ We do not permit the hedging or pledging of InterDigital stock by any employee, including executives. |
✓ We review compensation-related risk with an outside independent compensation consultant on an annual basis to ensure our plans do not create incentives that would put the company at risk of a material adverse effect. | ☒ We do not pay out dividend equivalents on unvested RSUs; accrued dividend equivalents are paid out only if and to the extent that the underlying RSU award vests. |
What Guides Our Program
Compensation Objectives and Philosophy
The primary purpose of our executive compensation program is to attract, retain and motivate talented individuals who will drive the successful execution of the company’s strategic plan. Specifically, we aim to:
•attract talented leaders to serve as executives by setting total compensation levels and incentive program targets at competitive levels for comparable roles in the marketplace;
•retain our executives by providing a balanced mix of base salary and short and long-term incentive compensation;
•motivate our executives by “paying for performance,” and rewarding individual performance and the accomplishment of corporate goals, as determined by the Human Capital Committee, through performance-based compensation; and
•align the interests of executives and shareholders by rewarding our executives for increasing our stock price over the long term and maximizing shareholder value with a substantial portion of total compensation in the form of direct ownership in our company through long-term equity awards and meaningful ownership guidelines.
Pay for Performance (Principal Elements of Pay)
Our executive compensation program is intended to hold our executives accountable for business results and compensate them for strong corporate performance and value creation for our shareholders by rewarding performance that meets or exceeds the goals established by the Human Capital Committee. Our NEOs’ 2025 compensation program was comprised of base salary, STIP and LTCP awards. Consistent with our compensation philosophy, the actual compensation received by our NEOs will vary based on individual and corporate performance measured against annual and long-term performance goals. Additionally, because a significant percentage of our NEOs’ pay is comprised of equity awards, the value of their pay increases and decreases with changes in our stock price. For 2025, approximately 92% of our CEO’s annual target compensation, and on average, 86% of the target compensation of our other NEOs, was comprised of STIP and LTCP awards and thus variable based on the company’s performance.


The Decision-Making Process
Role of the Human Capital Committee. The Human Capital Committee oversees our executive compensation program and has final approval with respect to the composition, structure and amount of all executive officer compensation. The Human Capital Committee is comprised of at least three independent members of the Board. Guided by its philosophy that the interests of key leadership should be aligned with the long-term interests of the company and its shareholders, the Human Capital Committee annually reviews and approves goals relevant to the performance-based incentive compensation of the CEO and other executive officers. The Human Capital Committee works very closely with management and the Human Capital Committee’s independent consultant to examine the effectiveness of the company’s executive compensation program throughout the year. Details of the Human Capital Committee’s authority and responsibilities are discussed above under “Board Structure and Committee Membership-Human Capital Committee” and are specified in the Human Capital Committee’s charter, which is available on the Investor Relations page of our corporate website.
Role of Executives. As part of the annual performance and compensation review for executives other than the CEO, the Human Capital Committee considers the CEO’s assessment of the other executives’ performances, reviewing major individual accomplishments and other recommendations of the CEO regarding their compensation. The CEO, along with the CFO, also reports to the Human Capital Committee on the company’s achievement of objectively measurable goals established under performance-based incentive programs.
Role and Independence of Advisors. The Human Capital Committee has authority to retain independent consultants and other experts to assist in carrying out its responsibilities. The Human Capital Committee selects the consultant, negotiates the fees paid and manages the engagement. The Human Capital Committee has engaged FW Cook, a national executive compensation consulting firm, to advise it and the rest of the Board on matters including, but not limited to, trends in executive compensation, compensation peer group composition, assessing total direct compensation of the executives as compared to the compensation peer group, and short and long-term incentive plan design and compensation of the company’s executive officers. Based on consideration of the factors as set forth in applicable SEC rules and listing standards of the Nasdaq Stock Market, the Human Capital Committee has determined that FW Cook has no conflicts of interest in providing its services.
Factors Considered in Setting Compensation Amounts and Targets. In establishing compensation amounts and incentive program targets for executives, the Human Capital Committee seeks to provide compensation that is competitive under current market conditions and industry practices. Accordingly, the Human Capital Committee annually reviews market data that is comprised of proxy-disclosed data from peer companies and information from nationally recognized published surveys for high-technology companies, adjusted for size.
Consistent with its review practices, in the fall of 2024, our compensation consultant FW Cook assisted the Human Capital Committee with its process of annually reviewing peer group companies for 2025 compensation purposes. The peer group approved by our Human Capital Committee was chosen based on an assessment of each company’s similarity with InterDigital with respect to business model, revenue and market capitalization. The Human Capital Committee’s objective in selecting this peer group was to include a mix of similar-sized public companies with a technology patent/licensing business and companies that operate in the system and application software sectors. Targeted companies generally had revenues between 0.4x and 2.5x of InterDigital's at the time of the analysis and market capitalization between 0.33x and 3.0x of InterDigital's. For 2025, ADTRAN was removed from the peer group because it did not meet the market size criteria and Everbridge was removed because it was acquired. Blackbaud was added as a replacement for the two removed peers.
The companies comprising the 2025 compensation peer group were as follows:
| | | | | | | | |
Adeia, Inc. | Dolby Laboratories, Inc. | Semtech Corporation |
Aspen Technology, Inc. | LiveRamp Holdings, Inc. | Silicon Laboratories, Inc. |
Blackbaud | Manhattan Associates, Inc. | Synaptics Inc. |
CSG Systems International, Inc. | Progress Software Corporation | Universal Display Corp |
Guidewire Software, Inc. | Qualys, Inc. | |
Digi International, Inc. | Rambus, Inc. | |
In the fall of 2024, FW Cook conducted an executive compensation review using peer group and market data from nationally recognized published surveys to provide the Human Capital Committee context on competitive compensation for comparable executive positions. There is no targeted benchmark level of compensation, but the data are used as reference points to guide the Committee in its efforts to set executive compensation levels and program targets at competitive levels for comparable roles in the marketplace. The Committee believes that executive pay should be determined using a holistic approach, taking into account a wide variety of factors, such as the importance of each executive officer’s role to the company, individual expertise, experience and performance, retention concerns, internal parity and relevant compensation trends in the marketplace, in making its final compensation determinations.
2025 Executive Compensation in Detail
Base Salary
Base salary is the fixed element of an executive’s cash compensation, which the company pays to afford each executive the baseline financial security necessary to focus on his or her day-to-day responsibilities. Base salaries for the executives are set at competitive levels to attract and retain highly qualified and talented leaders. The Human Capital Committee reviews and approves base salaries for the executives annually, however, executive base salaries are not subject to automatic annual adjustments.
The Human Capital Committee reviews market data and base salaries of executive officers in the company’s compensation peer group and considers the executive’s experience, scope of responsibility, importance to the company and individual performance when setting base salary. For 2025, the base salary remained flat for Mr. Pankaj and Ms. Hakoranta because market data showed that their salaries were within the median range for their respective positions. In order to remain competitive with comparable positions in their peer group, base salary increases were given to Messrs. Chen, Brezski and Schmidt for 2025. Set forth below are the 2024 and 2025 base salaries for our NEOs:
| | | | | | | | | | | | | | | | | |
| NEO | 2024 | | 2025 | | % Increase |
Liren Chen | $ | 710,000 | | | $ | 760,000 | | | 7 | % |
Richard J. Brezski | $ | 440,000 | | | $ | 475,000 | | | 8 | % |
Julia C. Mattis (1) | $ | 360,000 | | | $ | 400,000 | | | 11 | % |
Rajesh Pankaj | $ | 490,000 | | | $ | 490,000 | | | — | % |
Joshua D. Schmidt | $ | 400,000 | | | $ | 430,000 | | | 8 | % |
Eeva K. Hakoranta(2) | € | 411,000 | | | € | 411,000 | | | — | % |
(1) Ms. Mattis received an 8% increase to her base salary upon her promotion to Chief Licensing Officer in September 2025 after receiving an annual 3% merit increase in March 2025.
(2) Ms. Hakoranta received her salary and other cash compensation in euros.
Short-Term Incentive Plan
The annual STIP is designed to reward the achievement of corporate goals and individual accomplishments during each fiscal year. Individual STIP payouts are determined based on performance against pre-determined strategic corporate goals and individual performance. In 2025, the Human Capital Committee increased the Chief Executive Officer’s target bonus from 105% to 125% of base salary to better align with market trends. Ms. Mattis's target bonus was increased from 50% to 60% of base salary as a result of her promotion to Chief Licensing Officer in September 2025. No other changes were made to the target STIP levels. STIP payouts are capped at 200% of target for each executive.
| | | | | | | | | | | |
| NEO | 2024 Target STIP Level (% of Base Salary) | | 2025 Target STIP Level (% of Base Salary) |
Liren Chen | 105 | % | | 125 | % |
Richard J. Brezski | 75 | % | | 75 | % |
Julia C. Mattis | 50 | % | | 60 | % |
Rajesh Pankaj | 75 | % | | 75 | % |
Joshua D. Schmidt | 75 | % | | 75 | % |
Eeva K. Hakoranta | 75 | % | | 75 | % |
The STIP is designed to ensure that corporate performance is a primary factor in determining payout. Baseline funding of the STIP is determined entirely on corporate goal achievement with individual performance as a modifier. The STIP payout for 2025 was determined as follows:
Corporate Performance Goals. For 2025, the corporate performance goals for the company’s executives and the relative weights assigned to each were as follows, with a maximum payout of 200% of target:
| | | | | | | | | | | | | | | | | | | | |
2025 STIP Corporate Performance Goals: |
Performance Measure (relative weight) | | Description | | Goal/Objectives | | Determination of Payout Level |
Total Revenue (60%) | | Achieve specified amount of recognized revenue as reported in our financial statements | | Target is estimated recognized revenue as reported in 2025 financial statements Threshold = $660M Target = $710M | | Minimum threshold set, below which would yield 0% achievement Each $1 million above threshold equals 0.5% achievement up to target; each $1 million achievement above target equals 1.0% achievement above target |
Innovation (30%) | | Patent filings | | Meet or exceed specified number of first patent filings Target = 800 first patent filings | | Percent achievement equals first patent filings as % of target filings |
Evolution (10%) | | Execute Human Capital initiatives | | Execute Human Capital initiatives with focus on Cultural Transformation | | Bonus element pays out if specific, pre-defined strategic accomplishments are achieved |
These corporate performance goals were structured to challenge and motivate executives and intended to align the executive team around a key set of company performance objectives. The annual revenue targets are set to reflect the company's underlying performance and support sustainable growth. In setting performance goals, the Human Capital Committee recognizes that our reported revenue can fluctuate meaningfully from year-to-year due to the timing of revenue recognition, particularly the impact of "catch-up revenue", which reflects revenue attributable to periods prior to the execution of a license agreement. Catch-up revenue can be significant and episodic, and is typically recorded at the time multi-year licensing agreements are executed resulting in variability of annual reported revenue. For 2025, the target revenue goal of $710M includes material growth of our recurring revenue base but appears lower than reported 2024 revenue of $869M because 2024 reported revenue includes substantial catch-up contributions amounting to $460M. Our STIP targets are aligned with the company's recurring revenue base and expected operational performance related to new agreements and enforcement actions, promoting incentives that are achievable, within management's influence, and aligned with long-term shareholder value creation. Additionally, the goals further our long-term strategy to be a leading innovator, designer and developer of fundamental, horizontal technologies and to receive fair compensation from the companies that implement our patented innovations in their products and services across licensing programs. We want to grow our licensing revenue, grow and enhance our worldwide patent portfolio and execute on human capital initiatives. Our goal is to foster an environment where employees feel valued, respected and challenged in order to enable our workforce to continue to contribute to the company’s growth and sustained success.
On January 22, 2026, the CEO reported to the Human Capital Committee on the final achievement of the revenue and strategic corporate goals and provided his assessment with respect to individual NEOs’ performance for the year. Total revenue in 2025 was $834 million. The table below contains details of the achievement of each of the corporate strategic performance components of the STIP, along with the payout assigned to each component according to its level of achievement.
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
| Corporate Strategic Performance Goals: Outcomes |
Goal (Target metric weight) | | Threshold Payout | | Target Payout | | | Achievement | | Component Payout |
Total Revenue (60%) | | $660M 30% | | $710M 60% | | | Total Revenue of $834M Each $1M above $710M is 1.0% achievement (achieved 224% of target) | | 134% |
Innovation (30%) | | 0% | | 30% | | | 890 first patent filings (achieved 111% of target) | | 33% |
Evolution (10%) | | 0% | | 10% | | | Continued execution of Culture Development Plan (100% achievement) | | 10% |
Overall Corporate Achievement* | | | | | 178% |
* Although individual goal achievement is not capped, the overall STIP payout is capped at 200%.
Personal Performance Component. The personal performance component of each NEO’s STIP award is based on pre-established criteria and evaluated by the Human Capital Committee at the end of the year. For the CEO, the Human Capital Committee considered the Board’s assessment of his performance, as reflected in the assessment by the non-executive Chairman of the Board.
For 2025, Mr. Chen was further assessed on performance of the strategic corporate goals as his personal achievement of the following:
| | | | | |
| Goal | Achievements |
Revenue/ Financial Strength | InterDigital increased annualized recurring revenue to $582 million, up 24% year over year. Mr. Chen led the achievement of strong revenue while maintaining cost discipline, resulting in full-year adjusted EBITDA of $589 million and non-GAAP EPS of $15.31. |
| Innovation | Mr. Chen’s continued emphasis on and support of innovation drove above target achievement in 2025 leading to a 14% year-over-year growth of our patent portfolio to approximately 38,000 granted patents and applications and our 4th year of recognition as a global innovation leader by LexisNexis. |
| Evolution | Mr. Chen continued to support the evolution of the corporate culture to drive talent growth and retention by supporting our market competitive compensation program at all levels of the organization and our employee and leadership development programs. |
In addition to the strong financial results and continued focus on research and development, Mr. Chen led continued progress across all of the company's licensing verticals, including the completion of the Samsung smartphone license agreement, an agreement with HP Inc., the world's largest personal computer manufacturer, and the initiation of licensing enforcement initiatives against Disney+, Hulu + and ESPN+. Finally, the acquisition of the artificial intelligence (AI) startup Deep Render, completed in the fourth quarter 2025, is expected to strengthen the engineering team and advance the company's research in AI and video compression.
For the other NEOs, the Human Capital Committee reviewed the performance assessments provided by Mr. Chen with respect to each executive’s individual performance and also considered its own direct interactions with each NEO. The Human Capital Committee included the impact on achievement of the strategic corporate goals and how well such NEO’s department performed during the year with respect to the department’s goals/primary projects. After completing the evaluations, the Human Capital Committee determined that the personal performance achievement against objectives for each NEO employed by the company at the end of 2025 was as follows:
| | | | | | | | |
| NEO | | Personal Performance Factor (0%-200%) |
Liren Chen | | 100 | % |
Richard J. Brezski | | 100 | % |
Julia C. Mattis | | 100 | % |
Rajesh Pankaj | | 100 | % |
Joshua D. Schmidt | | 100 | % |
Eeva K. Hakoranta* | | NA |
*Ms. Hakoranta received a pro-rata portion of her 2025 STIP at actual corporate performance pursuant to the terms of her Employment Agreement. See "Payments upon termination without cause for Eeva Hakoranta".
STIP Payout Calculation. Using the formula presented above, the payout for each executive was based on both Corporate Achievement and Personal Performance. The following table lays out the calculations for each NEO employed by the company at the end of 2025:
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

* Ms. Hakoranta, upon termination, remained eligible for a pro-rated portion of her 2025 STIP based on company performance pursuant to the terms of her employment agreement; the pro-rated target bonus is included above.
Long-Term Compensation Program
The LTCP is designed to align management’s interests with those of the company’s shareholders to maximize the value of the company’s stock over the long term and to enhance retention efforts by incentivizing executive officers to drive the company’s long-term strategic plan. It consists of three components:
| | | | | | | | | | | | | | |
| Equity Vehicle | | What it Does | | Vesting Requirements |
Performance-based RSUs | | Aligns NEO and shareholder interests by tying value to both business results and future stock price. | | Achievement of specified performance goals is required for vesting. For performance that falls below threshold achievement, no equity vests; vesting is capped at 200% of target. Performance-based options’ exercise term is 10 years. |
Performance-based stock options | | Rewards for stock price appreciation and achievement of underlying goals. |
Time-based RSUs | | Focuses our executives on long-term share ownership and sustained value. | | Three-year ratable vesting of shares. |
2025 LTCP Grant
The Human Capital Committee determines annually the participation level and components of each executive officer’s LTCP award, considering market data and internal pay equity among the company’s NEOs and other executives to motivate and incentivize performance across the senior management team and encourage collaboration and shared responsibility for executing the company’s strategic plan. In 2025, the Human Capital Committee determined that approximately two-thirds of our CEO’s LTCP would be provided in performance-based equity, split equally between RSUs and options, with the remaining one-third in time-based RSUs. The LTCP mix for our other NEOs in 2025 remained at 50% performance-based RSUs and 50% time-based RSUs. The Human Capital Committee approved LTCP awards to the company’s employees, including the NEOs, which were granted on March 31, 2025. The 2025 LTCP grants were comprised of the following equity vehicles:
| | | | | | | | | | | | | | | | | |
| 2025 LTCP Grant: Equity Mix |
| NEO | Performance-Based RSUs | | Performance-Based Stock Options | | Time-Based RSUs |
Liren Chen | 33 1/3% | | 33 1/3% | | 33 1/3% |
Richard J. Brezski | 50 | % | | — | | | 50 | % |
Julia C. Mattis | 50 | % | | — | | | 50 | % |
Rajesh Pankaj | 50 | % | | — | | | 50 | % |
Joshua D. Schmidt | 50 | % | | — | | | 50 | % |
Eeva K. Hakoranta | 50 | % | | — | | | 50 | % |
The table below shows the target award values for the 2025 LTCP grant for each of the NEOs:
| | | | | | | | | | | | | | | | | | | | | | | |
| Performance-Based RSUs ($)(1) | | Performance-Based Stock Options ($)(2) | | Time-Based RSUs ($)(1) | | Total Value ($) |
Liren Chen | 2,666,666 | | | 2,666,667 | | | 2,666,667 | | | 8,000,000 | |

Julia C. Mattis (3) | 750,000 | | | — | | | 750,000 | | | 1,500,000 | |
Rajesh Pankaj | 1,500,000 | | | — | | | 1,500,000 | | | 3,000,000 | |
Joshua D. Schmidt | 1,000,000 | | | — | | | 1,000,000 | | | 2,000,000 | |
Eeva K. Hakoranta (4) | 1,400,000 | | | — | | | 1,400,000 | | | 2,800,000 | |
(1) Award amounts for performance-based and time-based RSUs were determined based on the closing price of InterDigital’s common stock on the date of grant.
(2) Individual award amounts for options were calculated based on Black-Scholes values; additional information can be found in footnote 5 to the Summary Compensation Table below.
(3) Ms. Mattis received a $500,000 LTCP award in March 2025 and another $1,000,000 LTCP award in December 2025 as a result of her promotion to Chief Licensing Officer in September 2025, for a total of $1,500,000 in LTCP awards.
(4) Ms. Hakoranta forfeited the 2025 LTCP performance-based RSUs upon her separation and she received a pro-rata portion of the 2025 LTCP time-based RSUs upon separation.
2025 LTCP Time-based RSUs. Time-based RSUs granted to our NEOs in 2025 vest over three years, with one-third of the RSUs vesting and being delivered on or about each of the first three anniversaries of the grant date.
2025 LTCP Performance-Based RSUs and Options. Performance-based RSUs and performance-based options (the “Performance Awards”) from the 2025 LTCP are earned based on the achievement of pre-determined goal(s) set by the Human Capital Committee. The metric for the 2025 LTCP goal is pro forma EBITDA, which measures overall profitability of the company. Pro forma EBITDA is a supplemental non-GAAP financial measure that InterDigital believes provides investors with important insight into our ongoing business performance. Additional information can be found in Appendix A.
The Performance Awards, if earned, may vest at the end of the three-year performance period (January 1, 2025 through December 31, 2027) based on specified threshold, target, and maximum average levels of pro forma EBITDA measured over the three-year performance period. Based on shareholder feedback, the goal will measure average pro forma EBITDA over the full three-year performance period rather than the highest four quarters during the performance period. If the threshold level of achievement is not met, there is no payout. Achievement of the threshold performance level will result in 50% of target payout. Goal achievement for performance that falls between the amounts established for threshold, target and maximum achievement above is calculated using linear straight-line interpolation between the target achievement level and the actual achievement level. The payout cannot exceed 200% of target.
Status of Prior LTCP Grants:
2021 LTCP Grant: Forty percent of the 2021 LTCP performance-based awards have a five-year performance period (January 1, 2021 through December 31, 2025) and were set as milestone awards that may vest based on achievement of certain Consumer Electronics Revenue Platform ("CE Revenue Platform") goals. Each milestone goal achievement provided for a partial vesting (25% of target), with each milestone being an additional $25 million of CE Revenue Platform (the amount of revenue from existing contracts for the next 12-month period). The first milestone was achieved in June 2020 and the second was achieved in December 2023. The third and fourth milestones were not achieved at the end of the performance period, and the corresponding portion of the awards were forfeited.
2023 LTCP Grant: The 2023 LTCP performance-based awards are earned based upon the achievement of specified threshold, target and maximum levels of pro forma EBITDA measured quarterly during years two through three of the performance period, January 1, 2023 through December 31, 2025, on a trailing four quarter basis. The highest consecutive four quarters determines goal achievement. If the threshold level of achievement is not met, there is no payout. The pro forma EBITDA goal associated with the 2023 LTCP was as follows:
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
| | Threshold | | Target | | Superior |
Pro forma EBITDA | | $ | 175M | | $ | 275M | | $ | 375M |
The CEO reported to the Human Capital Committee that the four-quarter period measured from Q2 2024 through Q1 2025 exceeded the superior achievement. Each trailing four quarter period during the second and third years of the performance period achieved pro forma EBITDA that exceeded the superior goal, with high-water mark of $737 million for the four-quarter period from Q4 2024 through Q3 2025. The Human Capital Committee determined that the company’s goal achievement exceeded superior performance and, as a result, 200% of the performance-based equity vested in March 2026. Pro forma EBITDA is a non-GAAP financial measure. See Appendix A for an explanation of how this metric is used and a detailed reconciliation to the most directly comparable GAAP measure.
Other Compensation-Related Practices, Policies and Guidelines
Stock Ownership Guidelines
To align the interests of our executive officers with those of our shareholders, the company has established stock ownership guidelines for its executive officers. The CEO’s target ownership level is an amount of company stock with a value of at least six times his current annual base salary. The company’s other executive officers are expected to own an amount of company stock with a value of at least two times their current annual base salary. The guidelines were amended in March 2025 to provide that the CEO’s target ownership level is at least six (up from five) times his annual salary.
For purposes of calculating the value of company stock holdings, each share is priced at a price per share/unit equal to the average closing price of the company’s common stock for the 200 trading days leading up to and including the calculation date. The 200-day average closing price was also amended to be calculated annually on June 1 each year, instead of on the date of the company’s annual meeting of shareholders.
Any executive who has not reached or fails to maintain their target ownership level must retain at least 50% of any after-tax shares derived from the vesting of any awards or from exercised options until their level is met. An executive may not make any disposition of shares that results in their holdings falling below the target level without the express approval of the Human Capital Committee. As of December 31, 2025, all of our executive officers had either met their target ownership level or had more time to do so, and all executive officers who had not yet met their target ownership level were in compliance with the guidelines.
Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information
We do not have a formal policy regarding the timing of awards of options in relation to our disclosure of material nonpublic information. Typically, the Human Capital Committee approves the amount and timing of the annual grant, including any option component thereof, at its regular quarterly meeting during first fiscal quarter. The Human Capital Committee does not grant option awards in anticipation of the release of material nonpublic information, and we do not time the release of material nonpublic information for the purpose of affecting the value of executive compensation.
No stock options were granted during 2025 in the periods beginning four business days before the filing of a quarterly report on Form 10-Q, the filing of an annual report on Form 10-K, or the filing or furnishing of a current report on Form 8-K that disclosed material nonpublic information, and ending one business day after the filing or furnishing of such report.
Clawback Policy
The company adopted a revised Clawback Policy in 2023, in compliance with applicable rules of Nasdaq and Section 10D and Rule 10D-1 of the Exchange Act. The policy requires the company to recover any incentive-based compensation from NEOs in the event of any accounting restatement as a result of the company’s material non-compliance with financial reporting requirements, to the extent that the incentive-based compensation exceeds the amount that the executive would have received based on the restated financial statements. The policy allows recoupment from certain other executives of the company. The Board delegated authority to the Human Capital Committee to oversee the policy’s administration.
Savings and Protection and Nonqualified Deferred Compensation Plans
The company’s Savings and Protection Plan (“401(k) Plan”) is a tax-qualified retirement savings plan pursuant to which employees, including NEOs, are able to contribute the lesser of 100% of their annual base salary and bonus or the annual limit prescribed by the Internal Revenue Service (“IRS”) on a pre-tax basis. The company provides a 50% matching contribution on the first 6% of an employee’s eligible earnings contributed to the 401(k) Plan, up to the cap mandated by the IRS. The company offers this benefit to encourage employees to save for retirement and to provide a tax-advantaged means for doing so.
As noted above, the IRS imposes limits on the amounts that an employee may contribute annually to tax qualified plans such as the 401(k) Plan. The company’s nonqualified deferred compensation plan (the “Deferred Compensation Plan”) provides a select group of management and highly compensated employees, including the NEOs, with an opportunity to defer up to 40% of their base salary and up to 100% of their STIP payment. For 2025, the company matched up to 50% of the first 6% of the participant’s eligible compensation, determined on a combined plan basis taking into account both the Deferred Compensation Plan and the 401(k) Plan. Matching contributions are made once annually after the end of the year. Participants vest one-third in company matching contributions after one year of service, two-thirds after two years of service and fully after three years of service, a vesting schedule identical to the 401(k) Plan. For more information about the nonqualified deferred compensation plan, see “Nonqualified Deferred Compensation.”
Severance Arrangements with NEOs
The company amended and restated the InterDigital, Inc. Executive Severance and Change in Control Policy (the “Executive Severance Policy”), which automatically renews for additional successive one-year periods (unless the company provides notice of non-renewal at least 30 days before the expiration of the term (as extended by any renewal period)), in September 2025. The policy applies to all NEOs except for Ms. Hakoranta, whose severance arrangements, in compliance with local law, were set forth in her employment agreement. Among other things, the Executive Severance Policy provides severance payments and benefits upon certain qualifying terminations of employment, including upon termination of the NEO’s employment by the company without Cause, and provides for enhanced payments and benefits if such termination occurs on or within one year after a Change in Control (two years for the CEO), each as defined in the Executive Severance Policy. Ms. Hakoranta’s employment agreement provided similar payments and benefits. The amendment added a requirement that eligible executives execute an Executive Mutual Agreement for Individual Arbitration in order to be eligible for the benefits under the Plan. See “Potential Payments upon Termination or Change in Control.”
Compensation-Related Risk Assessment
We have assessed our employee compensation policies and practices and determined that any risks arising from our compensation policies and practices are not reasonably likely to have a material adverse effect on the company. In reaching this conclusion, the Human Capital Committee considered all components of our compensation program and assessed any associated risks. The Human Capital Committee also considered the various strategies and measures employed by the company that mitigate such risk, including: (i) the overall balance achieved through our use of a mix of cash and equity, annual and long-term incentives and time- and performance-based compensation; (ii) our use of multi-year vesting periods for equity grants; (iii) limits on the maximum goal achievement levels and overall payout amounts under STIP and LTCP awards; (iv) the company’s adoption of, and adherence to, various compliance programs, including the Code of Ethics, a clawback policy, a contract review and approval process and signature authority policy and a system of internal controls and procedures; and (v) the oversight exercised by the Human Capital Committee over the performance metrics and results under the STIP and the LTCP. In addition, our compensation programs are reviewed with the Human Capital Committee’s compensation consultant on an annual basis to ensure plans do not create incentives that would put the company at excessive risk. Based on FW Cook's most recent review and the assessment described above, the Human Capital Committee concluded that any risks associated with our compensation policies and practices were not reasonably likely to have a material adverse effect on the company.
Taxation of Executive Compensation
For income tax purposes, public companies may not deduct any portion of compensation that is in excess of $1 million paid in a taxable year to certain “covered employees,” including our named executive officers, under Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”), subject to certain limited exceptions (which may not be applicable to us). Nevertheless, our board of directors believes that it should not be constrained by the requirements of Section 162(m) if those requirements would impair flexibility in compensating our named executive officers in a manner that can best promote our corporate objectives. We intend to continue to compensate our executive officers in a manner consistent with the best interests of our shareholders and reserve the right to award compensation that may not be deductible under Section 162(m) where the company believes it is appropriate to do so.
Accounting for Share-Based Compensation
We follow FASB ASC Topic 718 for our share-based compensation awards. FASB ASC Topic 718 requires companies to measure the compensation expense for all share-based compensation awards made to employees and directors, including stock options and RSUs, based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our NEOs may never realize any value from their awards. FASB ASC Topic 718 also requires companies to recognize the compensation cost of their share-based compensation awards in their income statements over the period that an executive officer is required to render services in exchange for the option or other award.
Human Capital Committee Report
The Human Capital Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on its review and discussions, has recommended to the Board that the Compensation Discussion and Analysis be included in this proxy statement and the company’s Annual Report on Form 10-K.

(1) Base salary increases, as applicable, became effective on March 1 of each year. Amounts reported reflect the value of base salary earned by each NEO during such years.
(2) Ms. Mattis received a one-time cash bonus in 2025 as additional compensation for her service as Interim Chief Licensing Officer. In connection with his hiring as CTO in 2022, Mr. Pankaj received a sign-on cash bonus, a portion of which was received in 2023.
(3) Amounts reported reflect the grant date fair value computed in accordance with FASB ASC Topic 718 for time-based RSU awards granted during the designated fiscal year. The assumptions used in valuing these awards are incorporated by reference to Notes 2 and 13 to our audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2025. Under generally accepted accounting principles, compensation expense with respect to stock awards granted to our employees is generally equal to the grant date fair value of the awards and is recognized over the vesting periods applicable to the awards.
(4) Amounts reported also reflect the value at the grant date of performance-based RSUs granted in such years based upon the probable outcome of the performance conditions for such awards, consistent with the estimate of aggregate compensation cost to be recognized over the service period determined as of the grant date under FASB ASC Topic 718, excluding the effect of estimated forfeitures. The assumptions used in valuing these awards are incorporated by reference to Notes 2 and 13 to our audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2025.
On March 31, 2025, the company granted performance-based RSU awards to its NEOs. As of the respective grant dates, consistent with the estimates determined as of the respective grant dates under FASB ASC Topic 718, the probable outcome of the performance conditions for these grants was estimated at 50% achievement and as a result, the grant date fair value was 50% of the target grant values. On December 15, 2025, Ms. Mattis was granted performance-based RSUs upon her promotion to Chief Licensing Officer and consistent with the estimates determined as of the grant date under FASB ASC Topic 718, the probable outcome of the performance condition for this grant was estimated at 170% of the target grant value.
The following table sets forth value of the performance-based RSUs granted to the NEOs in 2025 assuming that the highest level of performance conditions will be achieved and the grants vest at their maximum level of 200% of target:
| | | | | | | | |
| NEO | | Maximum Value Performance-Based RSU Awards 2025 LTCP ($) |
Liren Chen | | 5,333,333 |
Richard J. Brezski | | 2,800,000 |
Julia C. Mattis | | 1,500,000 |
Rajesh Pankaj | | 3,000,000 |
Joshua D. Schmidt | | 2,000,000 |
Eeva K. Hakoranta | | 2,800,000 |
(5) Amounts reported reflect the value recognized for financial reporting purposes in accordance with FASB ASC Topic 718. During 2025, the company granted performance-based options to Mr. Chen, as part of the 2025 LTCP. As of the grant date, consistent with the estimates determined as of the respective grant dates under FASB ASC Topic 718, the probable outcome of the performance conditions for the performance options granted under the 2025 LTCP was estimated at 50% achievement, and therefore the grant date fair value was 50% of the target grant value.
Assuming that the highest level of performance conditions will be achieved and the grant vests at its maximum level of 200% of target, the maximum grant date fair value of the performance-based stock options granted to Mr. Chen under the 2025 LTCP would be $5,333,333. The weighted-average assumptions underlying this valuation under the Black-Scholes option pricing model are as follows: expected term of 6.48 years; volatility of 39.10%; a risk-free interest rate of 4.02%; and a dividend yield of 1.17%.
(6) Amounts reported consist of payouts earned under the company’s 2025 STIP.
(7) The following table details each component of the “All Other Compensation” column in the Summary Compensation Table for fiscal year 2025:

| PSU | 3/31/2025 | | | | | | 3,386 | | 6,771 | | 13,542 | | | | 700,000 | |
(1) Amounts reported represent the potential threshold, target and maximum STIP payouts depending on the level of performance achieved under the STIP for fiscal 2025. Such amounts ranged from 0% (if threshold not met for revenue goal) to 200% of the target payout, representing the maximum payout possible under the STIP. For all NEOs, the actual amount earned for fiscal 2025, which is reported in the Summary Compensation Table above, was based on the company’s achievement of the 2025 strategic corporate goals established by the Human Capital Committee and individual performance of the NEO during 2025.
(2) Amounts reported represent the potential threshold, target and maximum number of PSUs the NEO could earn pursuant to his or her PSU award for the 2025 LTCP. 100% achievement of the performance goal associated with the award results in a 100% payout of the associated target amounts. Goal achievement for performance that falls between the amounts established for threshold, target and maximum achievement is calculated using straight-line interpolation between the target achievement level and the actual achievement level, with a threshold payout of 50% of target and a maximum payout of 200% of target.
(3) Amounts reported represent the potential threshold, target and maximum number of performance-based options our CEO could earn pursuant to the 2025 LTCP. 100% achievement of the performance goal associated with the award results in 100% vesting of the associated target number of options. Goal achievement for performance that falls between the amounts established for threshold, target and maximum achievement is calculated using straight-line interpolation between the target achievement level and the actual achievement level, with a threshold vesting of 50% of target and a maximum vesting of 200% of target.
(4) Grant date fair value of RSU awards is determined in accordance with FASB ASC Topic 718. The TRSU awards granted in 2025 are scheduled to vest ratably over a three year period. Amounts reported for performance-based RSUs is based upon the probable outcome of the performance conditions, consistent with the estimate of aggregate compensation cost to be recognized over the service period determined as of the grant date under FASB ASC Topic 718, excluding the effect of estimated forfeitures.
As of the date of grant, the probable outcome of the performance conditions for the PSUs granted pursuant to the 2025 LTCP was estimated at an expected achievement of 50%, and, as a result, their grant date fair value was 50% of the target grant value. Ms. Mattis was granted additional PSUs on December 15, 2025, upon her promotion; as of that date, the probable outcome of the performance conditions of the PSUs granted was 170%. See footnote 4 to the Summary Compensation Table above for the grant date fair value of the PSUs granted to the NEOs in 2025 assuming that the highest level of performance conditions will be achieved and the grants vest at their maximum level of 200% of target.
(5) Grant date fair value of performance-based option awards is determined in accordance with FASB ASC Topic 718. Amounts reported reflect the value at the grant date of the performance-based stock options granted in 2025 based upon the probable outcome of the performance conditions for such awards, consistent with the estimate of aggregate compensation cost to be recognized over the service period determined as of the grant date under FASB ASC Topic 718, excluding the effect of estimated forfeitures. As of the date of grant, the probable outcome of the performance conditions for these performance-based options granted pursuant to the 2025 LTCP was estimated at an expected achievement of 50%, and, as a result, their grant date fair value was 50% of the target grant value. See footnote 5 to the Summary Compensation Table above for the grant date fair value of the performance-based stock options granted to Mr. Chen in 2025 assuming that the highest level of performance conditions will be achieved and the grants vest at their maximum level of 200% of target.
(6) Ms. Hakoranta receives her salary and other cash compensation in euros. Amounts were converted to USD using an exchange rate of 1.0661.

Nonqualified Deferred Compensation
In 2013, the company introduced a nonqualified deferred compensation plan to complement the 401(k) Plan. The IRS imposes limits on the amounts that an employee may contribute annually to a 401(k) Plan account. The deferred compensation plan provides the company’s directors and designated select group of highly compensated employees, including the NEOs, with an opportunity to set aside additional compensation for their retirement. Pursuant to the terms of the deferred compensation plan, each eligible employee may elect to defer base salary and STIP payouts, and non-employee members of the Board may elect to defer Board fees, in each case, on a pre-tax basis and up to a maximum amount selected annually by the Human Capital Committee.
An employee participant or director may allocate deferrals to one or more deemed investments under the deferred compensation plan. The amount of earnings (or losses) that accrue to a participant’s account attributable to deferrals depends on the performance of investment alternatives selected by the participant. The deemed investment options are currently similar to those available under the 401(k) Plan. However, a participant’s election of investment alternatives as measuring devices for determining the value of a participant’s account does not represent actual ownership of, or any ownership rights in or to, the investments to which the investment alternatives refer, nor is the company in any way bound or directed to make actual investments corresponding to such deemed investments.
The company will not make any matching or discretionary contributions to the accounts of directors. However, the company may, but is not required to, make matching or discretionary contributions in cash to the accounts of employee participants. Any such company contributions are subject to a vesting schedule as determined by the Human Capital Committee. The specific terms for each plan year, including eligible compensation, minimum and maximum deferral amounts (by percentage of compensation) and matching terms, are determined by the Human Capital Committee.
Employee participant and director account payment obligations are payable in cash on a date or dates selected by the employee participant or director or upon certain specified events such as termination of employment, death or disability, subject to change in certain specified circumstances. An employee participant or director may elect to defer to a single lump-sum payment of his or her account, or may elect payments over time.
For the 2025 plan year, eligible employees could elect to defer from 1% to 40% of their base salary and from 1% to 100% of their STIP. Matching contributions are determined on a combined plan basis taking into account deferred amounts under both the 401(k) Plan and the deferred compensation plan. Deferral elections had to be made by December 31, 2024. For 2025, a participant’s total match for the 401(k) and deferred compensation plan was 50% of the combined contributions, up to 6% of the participant’s eligible compensation. Matching contributions under the deferred compensation plan were deemed to be notionally invested in investment alternatives elected by the NEO that are similar to those available to participants in the 401(k) Plan. Matching contributions are made once annually after the end of the year. Matching contributions vest ratably based on years of service of the participant over three years in one-third increments, with the first vesting occurring after one year of service.
The following table sets forth the relevant NEO information regarding the deferred compensation plan for 2025.

(1) Contributions include deferred 2025 salary amounts and deferred 2024 STIP amounts (corresponding to the portion of the 2024 STIP amount paid in 2025). The payouts of the 2025 STIP were not made until 2026. As a result, any deferrals of the 2025 STIP are not reflected in this column, instead deferrals of 2024 STIP, paid in 2025, are included in this column. For Messrs. Chen, Brezski and Pankaj, $300,153, $46,826 and $29,400, respectively, was included in the “Salary” column of the Summary Compensation Table. For Messrs. Chen and Schmidt, $1,118,250 and $180,000 respectively, was included in the "Non-Equity Incentive Plan Compensation" column of the 2024 Summary Compensation Table.
(2) For the 2025 plan year, the company matched deferrals up to 50% of the first 6% of the participant’s base salary and annual bonus, determined on a combined plan basis taking into account eligible compensation under both the 401(k) Plan and the deferred compensation plan during the 2025 calendar year. The amounts disclosed in this column reflect matching contributions (made by the company in 2026) for 2025 NEO deferral contributions. Amounts are included in the “All Other Compensation” column of the Summary Compensation Table for fiscal year 2025.
(3) The company does not pay guaranteed, above-market or preferential earnings on deferred compensation. Therefore, the amounts in this column are not included in the Summary Compensation Table. Balances include earnings (losses) credited to the NEO’s account from notional investment alternatives elected by the NEO from alternatives that are similar to those available to participants in the 401(k) Plan.
(4) Aggregate distribution made to Mr. Brezski in fiscal year 2025.
(5) Aggregate balance consists of employee contributions made in 2013 through 2025, company matching contributions for 2013 through 2025 and notional investment earnings through 2025.
Set forth below are the amounts reported in the aggregate balance that were previously reported in the “Salary,” “Non-Equity Incentive Plan Compensation” and “All Other Compensation” columns of the Summary Compensation Table for fiscal years 2013 through 2024, in the aggregate:
| | | | | | | | | | | | | | | | | |

The deferred compensation plan was implemented in 2013. Therefore, there are no amounts included that were reported as compensation to any NEO prior to 2013.
Potential Payments upon Termination or Change in Control
InterDigital, Inc. Executive Severance and Change in Control Policy
As discussed above in “Compensation Discussion and Analysis,” all NEOs except for Ms. Hakoranta are eligible for benefits pursuant to the Executive Severance Policy, which provides for severance pay and benefits, among other things, in certain events of termination of employment, as described below. Ms. Hakoranta’s severance arrangements, in compliance with local law, are set forth in her employment agreement, which provides similar payments and benefits. Ms. Hakoranta separated from the Company in 2025, and her actual separation payments and benefits are described below, see "Payments upon termination without cause for Eeva Hakoranta."
In 2025, we amended and restated our Executive Severance Policy to require execution of an Executive Mutual Agreement for Individual Arbitration in order to be eligible for benefits under such plan. Our policy continues to require both a Change in Control and a qualified termination in order to receive any change in control benefits (“double-trigger”) and does not provide for any excise tax gross-ups.
Pursuant to the terms of the Executive Severance Policy, in the event of a termination other than for Cause, death or disability, and provided the NEO executes a separation agreement in a form acceptable to the company (which may include, among other things, a broad release of all claims against the company, a non-disparagement, a non-solicitation and other standard restrictive covenant provisions) (a “Separation Agreement”), the NEO would be entitled to receive: (i) severance in an amount equal to one and a half times base salary then in effect (or, in the case of our CEO two times his base salary then in effect) paid over a period of 18 months; (ii) health coverage on terms and conditions comparable to those most recently provided for the period of one year (or, in the case of our CEO, 18 months) commencing upon the date of termination; (iii) outplacement services in an amount not to exceed $10,000, paid by the company directly to the entity providing such services and (iv) pro-rata vesting of outstanding equity awards pursuant to the terms of the applicable award agreements.
If the company terminates an NEO other than for Cause or such NEO terminates employment with us for Good Reason, in each case within one year (in the case of our CEO, two years) following a Change in Control of the company and provided that he or she executes a Separation Agreement, pursuant to the terms of the Executive Severance Policy, the NEO would be, entitled to (i) severance in an amount equal to two times base salary then in effect plus one times the target bonus under the STIP then in effect (in the case of our CEO, two times the target bonus) and (ii) an amount equal to the cost of continued health coverage on terms and conditions comparable to those most recently provided for the period of 24 months, in each case, paid in a lump sum 60 days after date of termination. Termination for Good Reason means the NEO’s resignation of employment with the company follows the occurrence of one or more of the following, in each case without the NEO’s consent: (i) a material diminution in the NEO’s base salary or in the NEO’s target bonus opportunity under the STIP as in effect for the year in which the termination occurs; (ii) a material diminution in the NEO’s title, authority, duties or responsibilities; (iii) a material failure to comply with payment of the NEO’s compensation; (iv) relocation of the NEO’s primary office more than 50 miles from the NEO’s current office; or (v) any other action or inaction that constitutes a material breach by the company of the Executive Severance Policy or the company’s NDAIA.
Under the Executive Severance Policy, Change in Control has the same meaning as set forth in the company’s 2025 Equity Plan.
The following table summarizes the benefits that become payable to an NEO (other than Ms. Hakoranta) at, or following, retirement, resignation, Change in Control, qualifying termination after Change in Control, termination with Cause, resignation with Good Reason, and termination due to death or disability, including severance payments payable pursuant to the Executive Severance Policy as well as the vesting of outstanding equity awards:

Performance-based options(8) | | Forfeit unvested awards | | Pro-rata vesting of performance-based equity that is in its last year of the applicable performance period | | Awards must be assumed/ substituted by successor or vest in full | | Greater of Target or actual performance(9) |
(1) The retirement of an NEO would trigger the distribution of such NEO’s deferred amounts under the deferred compensation plan, if applicable, in accordance with his or her applicable distribution elections.
(2) If Mr. Chen resigns for Good Reason (outside a Change in Control period), as defined in the Chen Offer Letter, he is eligible for severance and benefits per the Executive Severance Policy and is also eligible for accelerated vesting pursuant to the terms of his equity award agreements.
(3) Pursuant to the terms of the Chen Offer Letter and as applicable to the Executive Severance Policy, “Cause” is defined as follows: (i) acts or omissions constituting gross negligence, recklessness or willful misconduct with respect to Mr. Chen’s obligations to the company, in each case which results in material harm to the business or reputation of the company; (ii) willful and material breach of his Nondisclosure and Assignment of Ideas Agreement (“NDAIA”); (iii) a conviction or entry of a plea of nolo contendere for fraud, misappropriation or embezzlement, any felony, or any crime of moral turpitude; or (iv) the willful neglect of duties as determined in the sole and exclusive discretion of the Board of Directors.
(4) Qualified Termination following Change in Control occurs if terminated without Cause or for Good Reason within 24 months post Change in Control for Mr. Chen or within 12 months post Change in Control for other NEOs. Under the Executive Severance Policy, Change in Control has the same meaning as set forth in the company’s Equity Plan. Termination for Good Reason means the NEO’s resignation of employment with the company follows the occurrence of one or more of the following, in each case without the NEO’s consent: (i) a material diminution in the NEO’s base salary or in the NEO’s target bonus opportunity under the STIP as in effect for the year in which the termination occurs; (ii) a material diminution in the NEO’s title, authority, duties or responsibilities; (iii) a material failure to comply with payment of the NEO’s compensation; (iv) relocation of the NEO’s primary office more than 50 miles from the NEO’s current office; or (v) any other action or inaction that constitutes a material breach by the company of the Executive Severance Policy or the company’s NDAIA.
(5) For a Qualified Termination of Mr. Chen, 200% of base salary and for the other NEOs, 150% of base salary.
(6) See “Aggregate Balance at Last FYE” column in “Nonqualified Deferred Compensation Table” for amounts payable for all NEOs. If an NEO’s employment terminates with the company for any reason, the NEO would receive a distribution of deferred amounts under the deferred compensation plan, including the vested portion of any company matching or discretionary contributions, in accordance with the NEO’s applicable distribution elections. However, in the event of a termination due to death, the NEO's beneficiary would receive the balance of deferred compensation account in a lump sum as soon as administratively practicable. In the event the NEO is involuntarily terminated by the company for Cause, the NEO would receive the balance of the deferred compensation account in a lump sum within 90 days of the date of termination. In the event of a Change in Control, as defined by the deferred compensation plan, the NEO would receive a distribution of the account balance in a lump sum as soon as administratively practicable, but in no event later than 30 days from the effective date of the Change in Control.
(7) If an NEO’s employment terminates due to death or disability or the NEO is terminated by the company without Cause, the NEO would be entitled to pro-rata vesting of all time-based RSUs. The pro-rata portion of each grant is determined by multiplying the total number of RSUs by a fraction equal to the number of days during the period beginning on the grant date or most recent vest date and ending on the original vesting date (“Restricted Period”) for which the NEO was employed by the total number of days during the Restricted Period. In the event of termination without Cause, the prorated vesting is conditioned upon the NEO’s execution of a release of claims in favor of the company within 60 days following termination of employment.
(8) If an NEO’s employment is terminated by the company without Cause or by reason of the NEO’s death or disability during the last year of a Performance Period for performance-based RSUs or performance-based options, the performance-based RSUs or options will vest as to a prorated portion (based on the number of days the NEO was employed during the applicable performance period) of the number of RSUs or options that would have otherwise vested according to actual performance during the performance period. In the event of termination without Cause, the prorated vesting is conditioned upon the NEO’s execution of a release of claims in favor of the company within 60 days following termination of employment.
(9) Outstanding performance-based equity awards provide for vesting at the greater of target or actual performance in the event of termination following a Change in Control.
Post-Termination Obligations
Each of the NEOs is bound by certain confidentiality obligations, which extend indefinitely. In addition, each of the NEOs is bound by certain covenants protecting our right, title and interest in and to certain intellectual property that either has been or is being developed or created in whole or in part by the NEO.
Taxes
In the event that the payments made to an NEO upon termination constitute “parachute payments” pursuant to Section 280G of the Code, the Executive Severance Policy provides that the payments will be either (i) reduced to such lesser amount that would result in no amount being subject to excise tax or (ii) made in full, whichever produces the larger after-tax net benefit to the NEO. The Executive Severance Policy does not provide for an excise tax “gross-up.”
Payments upon Termination without cause - Eeva Hakoranta
Ms. Hakoranta’s severance arrangements, in compliance with local law, are set forth in her employment agreement, which provides similar payments and benefits as the Executive Severance Policy. Pursuant to the terms of her employment agreement, as a result of Ms. Hakoranta's separation from InterDigital, she was entitled to and did receive (i) severance in an amount equal to eighteen (18) months of base salary; (ii) a pro-rated portion of the 2025 annual incentive bonus at actual corporate performance; (iii) outplacement services; and (iv) pro-rata vesting of outstanding equity awards pursuant to the terms of the applicable award agreement. See "Summary Compensation Table".
Potential Payments upon Termination or Change in Control
The following table reflects the potential payments and benefits that would be provided to each NEO upon: (i) Resignation or Retirement; (ii) resignation by Mr. Chen for Good Reason unrelated to a Change in Control; (iii) termination due to disability or death; (iv) termination without Cause; (v) Change in Control of the company without a termination; and (vi) termination by the company without Cause or by Mr. Chen within two years of a Change in Control or by an NEO for Good Reason within one year of a Change in Control of the company.
The amounts shown assume that the termination (or the Change in Control in the case of (v)) was effective as of December 31, 2025, and the price per share used to calculate the value of the company’s stock awards was $318.38, the per share closing market price of our common stock on December 31, 2025. The amounts reflected are estimates of the amounts that would have been paid to the NEOs upon their termination pursuant to existing terms in place on December 31, 2025. In addition, note that the tables below do not take into account the cutback provision described above under “Termination Scenarios - Taxes.” As a result, the actual amounts paid could be lower than what is presented. The actual amounts to be paid can be determined only at the time the events described above actually occur.

(1) The amount represents a cash severance payment equal to 200% of Mr. Chen’s base salary in the case of resignation for Good Reason or termination without Cause at any time or within twenty-four months of a Change in Control, both per the Terms of the Executive Severance Policy.
(2) The amount represents the NEO’s STIP paid out at target (or in the case of Mr. Chen at 200% of target) for resignation for Good Reason or termination without Cause within 12 months of a Change in Control (or in the case of Mr. Chen, 24 months).
(3) The amount represents the value of health coverage pursuant to COBRA for a period of 18 months after termination (or 24 months after termination following a Change in Control) on terms and conditions comparable to those most recently provided to Mr. Chen as of December 31, 2025, pursuant to the Executive Severance Policy.
(4) The amount represents the payment prescribed under our basic term life insurance program calculated as follows: 1.5 times base salary, up to a maximum of $750,000 and the monthly benefit that would become payable under our executive long term disability plan in the event of termination due to disability on December 31, 2025, calculated as follows: 60% of NEO’s monthly earnings (i.e., pre-tax base salary and annual bonus), up to $10,000, and a supplemental monthly payment of up to $10,000. Monthly benefits would be payable until the earlier of (a) the date NEO ceases to be totally disabled or (b) NEO’s 65th birthday.
(5) This amount represents the value, at December 31, 2025, of the NEO's outstanding performance-based equity granted for the 2021 and 2023 LTCP cycles and time-based RSUs granted for the 2023, 2024 and 2025 LTCP cycles that would vest upon termination after resignation for Good Reason (in the case of Mr. Chen) or due to disability, death or termination by the company without Cause. Pursuant to the terms of the awards, the NEOs would forfeit eligibility to receive any payout of performance-based RSUs or options granted for the 2024 and 2025 LTCP since a termination on December 31, 2025, would not be in the final year of the applicable performance periods. For time-based RSU awards, the amounts were prorated based on the portion of the vesting period that would have transpired prior to cessation of employment. For the performance-based equity awards granted for the 2021 LTCP (the performance period for which ended December 31, 2025), the amount reflects the forfeiture of outstanding performance-based awards based on actual performance. For the 2023 LTCP (the performance period for which ended December 31, 2025), the amount reflects the actual payout of 200% of target for the 2023 LTCP (based on actual performance over the performance period) prorated based on the portion of the vesting period that would have transpired prior to cessation of employment. All RSU amounts include accrued dividend equivalents, which are paid out in the form of additional shares of common stock at the time, and only to the extent, that the awards vest.
(6) This amount represents the value, at December 31, 2025, of the NEO's unvested time-based RSUs and performance-based equity awards granted for the 2021, 2023, 2024 and 2025 LTCPs that would vest upon termination (by us without Cause or by the NEO for Good Reason) within twelve months (twenty four months for Mr. Chen) following a Change in Control. All performance-based RSU and option awards would be paid out at the greater of target or actual performance. All RSU amounts include accrued dividend equivalents, which are paid out in the form of additional shares of common stock at the time, and only to the extent, that the awards vest.
(7) This amount represents the balance, at December 31, 2025, of the NEOs deferred compensation plan account (including matching contributions), which is payable (a) upon retirement, disability or his voluntary termination of employment with the company for any reason pursuant to the NEO’s deferral elections, (b) upon death, in a lump sum as soon as administratively practicable following his death, (c) upon an involuntary termination by the company, in a lump sum within 90 days of the date of termination and (d) upon a Change in control, in a lump sum as soon as administratively practicable, but in no event later than 30 days from the effective date of the Change in control.
(8) The amount represents cash payments under our Executive Severance Policy equal to 1.5 times an NEO’s base salary for termination without Cause and two times an NEO’s base salary for termination without Cause or resignation for Good Reason within twelve months of a Change in Control.

(4) The following summarizes the valuation assumptions used for stock option awards included as part of Compensation Actually Paid:
•Expected life of each stock option is based on the “simplified method” using an average of the remaining vest and remaining term, as of the vest/FYE date.
•Strike price is based on each grant date closing price and asset price is based on each vest/FYE closing price.
•Risk free rate is based on the Treasury Constant Maturity rate closest to the remaining expected life as of the vest/FYE date.
•Historical volatility is based on daily price history for each expected life (years) prior to each vest/FYE date. Closing prices provided by S&P Capital IQ are adjusted for dividends and splits.
•Represents annual dividend yield on each vest/FYE date.
(5) Assumptions used in the valuation of equity awards for purposes of calculating Compensation Actually Paid were materially the same as at grant date, except for adjusting for expected performance of performance-based RSUs at each measurement date.
(6) Non-CEO NEOs reflect the average Summary Compensation Table total compensation and average Compensation Actually Paid for the following executives by year:
