  13. What are their backgrounds?

    What are their backgrounds? Derek Aberle, 54, has been a director of the company since September 2022. Mr. Aberle is Co-founder and Executive Vice Chairman of Virewirx, Inc. (formerly XCOM Labs), a company focused on developing and commercializing advanced wireless and XR technologies. Prior to that, from 2000 through 2018, Mr. Aberle served in various senior executive roles at Qualcomm, including as President of Qualcomm from 2014 through 2018. Beginning in 2008, Mr. Aberle served as a member of Qualcomm’s executive committee, as Executive Vice President and President of Qualcomm Technology Licensing from 2008 through 2011 and as Executive Vice President and Group President from 2011 through 2014 where, among other things, he led Qualcomm’s technology and IP licensing business, helping to significantly grow its global licensing business and negotiating deals with its largest licensees. Mr. Aberle also served as Chief Executive Officer and director of Prospector Capital Corp., a special purpose acquisition company, from its inception in 2020 through 2023. Prior to Qualcomm, Mr. Aberle was an attorney with the international law firms Pillsbury Winthrop and Heller Ehrman. Mr. Aberle also serves on the boards of directors of Virewirx, LeddarTech (LDTC) and EvoNexus. The Board has concluded that Mr. Aberle should serve as a director of the company because of his years of experience in patent licensing and his global business acumen and leadership. Samir Armaly, 51, is currently a director and advisor to various technology companies. Mr. Armaly served as President, IP of Adeia, Inc., a leading IP licensing business, from June 2020 to March 2022. From 2017 to 2020, he was a Strategic IP Advisor to the CEO and Board of Directors of TiVo Corporation. From 2001 to 2017, Mr. Armaly held various senior management positions and ran the video IP licensing business of Gemstar – TV Guide and its successor, Rovi Corporation. Previously, Mr. Armaly was an IP attorney in private practice representing media and technology companies. He graduated from the University of Missouri Columbia with a B.S. degree in Mechanical Engineering and received his J.D. degree from the University of California Berkeley. The Board has concluded that Mr. Armaly should serve as a director of the company because he is a recognized IP expert, having run one of the world’s largest patent licensing businesses, and has particular expertise in the media and technology markets. Lawrence (Liren) Chen, 53, has been a director of the company since April 2021, when he was also appointed as our President and Chief Executive Officer. Mr. Chen joined InterDigital from Qualcomm where he served since August 2019 as Senior Vice President, Global Head of IP, Legal Counsel. In that role, Mr. Chen was responsible for overseeing Qualcomm’s world-wide intellectual property portfolio (patent, copyright, trademark and open source) and led technology, business strategy, product management and global eco-system development for Qualcomm Technology Licensing. In the 23 years preceding that, Mr. Chen served in various IP and technology roles at Qualcomm, including as Senior Vice President of Engineering, Legal Counsel. He holds 28 granted patents in the U.S. and over 120 granted patents worldwide. Mr. Chen earned his bachelor’s degree in Automation from Tsinghua University, Beijing; his M.S.E.E. from the University of Maine; his M.B.A. from San Diego State University; and his J.D. degree from the University of San Diego. Joan H. Gillman, 60, has been a director of the company since April 2017. From 2006 to 2016, Ms. Gillman served as Executive Vice President of Time Warner Cable, Inc. (“Time Warner Cable”), as well as Chief Operating Officer of Time Warner Cable Media and President of Time Warner Cable Media, LLC. Ms. Gillman joined Time Warner Cable as Vice President of Interactive TV and Advanced Advertising in 2005. Prior to Time Warner Cable, among other roles, she served as the President of Static2358, the interactive TV, games and production subsidiary of OpenTV, and as Director, Business Development, of British Interactive Broadcasting, the digital and interactive TV joint venture between BSkyB, BT, HSBC and Matsushita. Ms. Gillman began her career working in public affairs, serving in various roles for a U.S. Senator, including as Legislative Director and State Director. From October 2016 to February 2021, Ms. Gillman was a member of the board of directors of Centrica plc, an international energy and services company based in the United Kingdom where she served on the safety, health, environment, security, remunerations and ethics and nominating committees. In addition, since November 2016, she has served on the board of directors of Airgain, Inc., a leading provider of embedded antenna technologies used to enable high performance wireless networking, and she is currently a member of such board’s audit committee, and chairs the nominating and corporate governance committee, as well as the board of directors of Cumulus Media, which she joined in June 2018 and where she is a member of the compensation and nominating committees. Since May 2018, she has also chaired the Jesuit Volunteer Corps and is the Foundation Manager and Trustee of the David T. Langrock Foundation. The Board has concluded that Ms. Gillman should serve as a director of the company because her more than 20 years of executive experience in the media and communications industries and her knowledge of content development and distribution as well as key areas like partnership, mergers and acquisitions and marketing make her a valuable resource and strengthen the company’s knowledge of the companies and industries shaping its existing and future markets. S. Douglas Hutcheson, 68, has been a director of the company since July 2014, and he assumed the role of Chairman of the Board in June 2015. From 2019 to 2024, Mr. Hutcheson served as the Executive Chairman of Kymeta Corporation, an electronically steerable terminal manufacturer and provider of services for global connectivity. He also served as the co-CEO of Kymeta from 2021 to 2024. Since 2015, Mr. Hutcheson has served as a senior advisor of Technology, Media and Telecom for Searchlight Capital, a global private investment firm. From March 2014 through May 2017, Mr. Hutcheson served as Chief Executive Officer and a director of Laser, Inc., a corporation created in connection with the acquisition of Leap Wireless International, Inc. (“Leap Wireless”), a wireless communications carrier, by AT&T in March 2014. Prior to March 2014, Mr. Hutcheson served as Chief Executive Officer of Leap Wireless and its operating subsidiary, Cricket Communications, for nine years, where he was responsible for developing and implementing strategy, all operations, and the oversight of all relationships and partnerships. Before serving as Chief Executive Officer, Mr. Hutcheson held other executive positions at Leap Wireless, including President and Chief Financial Officer. Prior to joining Leap Wireless, he was Vice President of Marketing in the wireless infrastructure division at Qualcomm for three years, where he led multiple teams. He previously served on the boards of directors of Leap Wireless from 2005 to 2014 and Pitney Bowes from 2012 to 2023. The Board has concluded that Mr. Hutcheson should serve as a director of the company because, with his significant operational and financial expertise as an experienced former chief executive officer of a wireless communications company and his broad business background, which includes strategic planning and product and business development and marketing, he brings valuable insight that is needed to evolve and execute the company’s strategy. He also qualifies as an audit committee financial expert.

Mr. Kritzmacher serves on the board of directors of Unisys and currently serves on the audit & finance and security & risk committees of such board. The Board has concluded that Mr. Kritzmacher should serve as a director of the company because he is a veteran of the telecommunications and high technology industries with extensive operational and leadership experience and financial expertise. As such, Mr. Kritzmacher contributes valuable advice and guidance, especially with respect to complex financial and accounting issues, and qualifies as an audit committee financial expert.

John D. Markley, Jr., 58, has been a director of the company since November 2016. Since 2009, Mr. Markley has served as Managing Partner of Bear Creek Capital Management, an investment firm focused on the cloud computing, mobile and communications infrastructure sectors.

He also qualifies as an audit committee financial expert. Jean F. Rankin, 65, has been a director of the company since June 2010.

Prior to joining Agere in 2000, Ms. Rankin was responsible for corporate governance and corporate center legal support at Lucent, including mergers and acquisitions, securities laws, labor and employment, public relations, ERISA, investor relations and treasury. She also supervised legal support for Lucent’s microelectronics business. The Board has concluded that Ms. Rankin should serve as a director of the company because she has extensive experience and expertise in matters involving intellectual property licensing, the company’s core business, and her current and former roles as chief legal officer and corporate secretary at other publicly traded companies enable her to contribute legal expertise and advice as to best practices in corporate governance.

  23. What Guides Our Program

    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, subject to Board review. The Human Capital Committee is comprised of at least three independent members of the Board. Guided in the execution of its primary functions by the Board’s 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 Chief Executive Officer 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 our website at on the Investors section of our website at http://ir.interdigital.com under the heading “Governance—Committee Charters”. Role of Executives. As part of the annual performance and compensation review for executives other than the Chief Executive Officer, the Human Capital Committee considers the Chief Executive Officer’s assessment of the other executives’ departmental and individual performances, reviewing major individual accomplishments and any other recommendations of the Chief Executive Officer regarding their compensation. The Chief Executive Officer also reports to the Human Capital Committee on the company’s achievement of objectively measurable goals established under performance-based incentive programs, based upon data provided by management. 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. For 2023 and previous years, the Human Capital Committee engaged Pearl Meyer, 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 Pearl Meyer has no conflicts of interest in providing its services. In December 2023, the Human Capital Committee ended its engagement with Pearl Meyer and engaged FW Cook, a national compensation consulting firm, as its new compensation consultant. Similarly, as part of the engagement process with FW Cook, the Human Capital Committee 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 in light of 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 2022, Pearl Meyer assisted the Human Capital Committee with its process of identifying peer group companies for 2023 compensation purposes. When choosing compensation peers, we not only look for companies with similar revenue in the communications equipment industry, but also companies for which licensing revenue is a significant component of their total revenue stream (approximately 20% to 100% of total revenue) and that have a relatively similar profit margin and market capitalization. We removed Inolavan Holdings, Inc. because it was acquired and taken private in 2021. No additional companies were added. The companies comprising the 2023 compensation peer group were as follows:

  37. 2023 Executive Compensation in Detail

    2021 LTCP Grant: The 2021 LTCP performance-based awards are earned based upon the achievement of pro forma EBITDA and Consumer Electronics Revenue Platform goals. Sixty percent of the target performance awards were eligible to vest at the end of a three-year performance period (January 1, 2021, through December 31, 2023) based on specified threshold, target, and maximum levels of pro forma EBITDA measured quarterly during years two and three of the performance period, 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 2021 LTCP was as follows:

  38. 2023 Executive Compensation in Detail

    The Chief Executive Officer reported to the Human Capital Committee that the four-quarter period with the highest pro forma EBITDA during the measurement period was Q2 2022 through Q1 2023, in which period pro forma EBITDA was $371.3 million. The Human Capital Committee determined that the company’s goal achievement exceeded the superior performance goal and, as a result, 200% of the performance-based equity allocated to the pro forma EBITDA goal vested in March 2024. 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. The remaining portion of the Performance Awards granted under the 2021 LTCP cycle may vest based on the performance metric of Consumer Electronics Revenue Platform. We structured 40% of the 2021 LTCP as a set of milestones towards achieving our five-year goal for our Consumer Electronics Revenue Platform (such awards, “Milestone Awards”). For each of the four milestones that is achieved, 25% of the executives’ target Milestone Awards will vest. The Milestone Awards may vest at any time during the five-year performance period (January 1, 2021, through December 31, 2025), to the extent that one or more of the milestones are achieved. The Human Capital Committee determined that the second of these milestones was achieved in the third quarter of 2023, resulting in the vesting of 25% of target Milestone Awards in December 2023. CEO New Hire Awards: The Human Capital Committee approved the award of performance-based RSUs and performance-based options (“New Hire Awards”) as part of Mr. Chen’s New Hire equity awards in 2021. The actual number of New Hire Awards that may vest is determined by the achievement of one of more of diversified revenue platform goals. The diversified revenue platform goals measure achievement of specified amounts of revenue platform using forecasted revenue for a twelve month look-forward period. Similar to the 2021 LTCP Milestone Awards, the New Hire Awards may vest at any time through December 31, 2025. The Human Capital Committee determined that the fifth Milestone was achieved in the third quarter of 2023 which drove a 60% payout of Mr. Chen’s New Hire Awards. One additional milestone remains eligible to vest. Total payout on the New Hire Awards cannot exceed 300% of target.

  39. Other Practices, Policies and Guidelines

    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.

  46. Summary Compensation Table

    On March 31, 2023, the company granted performance-based RSU awards to its NEOs. As of that 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 these grants was estimated at 50% achievement and as a result, the grant date fair value was 50% of target grant value. The following table sets forth the grant date fair value of the performance-based RSUs granted to the NEOs in 2023 assuming that the highest level of performance conditions will be achieved and the grants vest at their maximum level of 200% of target:

  48. Summary Compensation Table

    | (5) Amounts reported reflect the value recognized for financial reporting purposes in accordance with FASB ASC Topic 718. During 2023, the company granted performance-based options to Mr. Chen, as part of the 2023 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 these grants was estimated at 50% achievement, and therefore the grant date fair value was 50% of the target grant value. |

  49. Summary Compensation Table

    Assuming that the highest level of performance conditions will be achieved and the grant vests at its maximum level of 200% of target, the grant date fair value of the performance-based stock options granted to Mr. Chen in 2023 would be $3,000,000. The weighted-average assumptions underlying this valuation under the Black-Scholes option pricing model are as follows: expected term of 7.48 years; volatility of 32.80%; a risk-free interest rate of 3.55%; and a dividend yield of 1.92%.

  91. Nonqualified Deferred Compensation

    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 on an annual basis 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 2023 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, 2022. For 2023, a participant’s combined match for the 401(k) and deferred compensation plan was 50% of the combined deferrals up to 6% of the participant’s eligible deferrals, and 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 2023.

  92. Nonqualified Deferred Compensation

    | (1) Contributions include deferred 2023 salary amounts and deferred 2022 STIP amounts (corresponding to the portion of the 2022 STIP amount paid in 2023). The payouts of the 2023 STIP were not made until 2024. As a result, any deferrals of the 2023 STIP are not reflected in this column. For Messrs. Chen, Brezski and Cohen, $282,554, $43,322, and $30,758, respectively, was included in the “Salary” column of the Summary Compensation Table. |

  94. Nonqualified Deferred Compensation

    | (2) For the 2023 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 amounts deferred under both the 401(k) Plan and the deferred compensation plan during the 2023 calendar year. The amounts disclosed in this column reflect matching contributions (made by the company in 2024) for 2023 NEO deferral contributions. Amounts are included in the “All Other Compensation” column of the Summary Compensation Table for fiscal year 2023. |

  95. Nonqualified Deferred Compensation

    | (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. |

  96. Nonqualified Deferred Compensation

    | (4) Aggregate balance consists of employee contributions made in 2013 through 2023, company matching contributions for 2013 through 2023 and notional investment earnings through 2023. |

  97. Nonqualified Deferred Compensation

    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 2022, in the aggregate:

  99. Nonqualified Deferred Compensation

    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

  101. InterDigital, Inc. Executive Severance and Change in Control Policy

    | (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 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. |

  102. Potential Payments upon Termination or Change in Control

    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 or Ms. Hakoranta for Good Reason unrelated to a Change in Control; (iii) termination due to disability or death; (iv) termination without Cause; (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; and (vii) Change in Control of the company without a termination. The amounts shown assume that the termination (or the Change in Control in the case of (vii)) was effective as of December 31, 2023, and the price per share used to calculate the value of the company’s stock awards was $108.54, the per share closing market price of our common stock on December 31, 2023. 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 at December 31, 2023. 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.

    | (4) The following summarizes the valuation assumptions used for stock option awards included as part of Compensation Actually Paid: |

  131. Pay Versus Performance

    | • | 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. |

  132. Pay Versus Performance

    | • | Strike price is based on each grant date closing price and asset price is based on each vest/FYE closing price. |

  133. Pay Versus Performance

    | • | Risk free rate is based on the Treasury Constant Maturity rate closest to the remaining expected life as of the vest/FYE date. |

  134. Pay Versus Performance

    | • | 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. |

  135. Pay Versus Performance

    | • | Represents annual dividend yield on each vest/FYE date. |

  136. Pay Versus Performance

    | (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. |

  145. Chief Executive Officer Pay Ratio

    Chief Executive Officer Pay Ratio We believe our executive compensation program must be consistent and internally equitable to motivate our employees to perform. The Human Capital Committee monitors the relationship between the pay of our executive officers and the pay of our non-executive employees. The Human Capital Committee reviewed a comparison of our Chief Executive Officer’s annual total compensation in fiscal year 2023 to that of the median of all other employees for that same period. Our Chief Executive Officer’s total 2023 compensation, as set forth in the Summary Compensation Table above, was $4,773,160. A new median employee was identified in 2023. The median employee’s total 2023 compensation was approximately $170,724, making our Chief Executive Officer’s pay in 2023 approximately 28 times the pay of our median employee. The pay ratio described above is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. The median employee was identified in by determining the compensation for each employee using the following consistently applied compensation measures:

  146. Chief Executive Officer Pay Ratio

    | • | Annual Salary for fiscal year; |

  147. Chief Executive Officer Pay Ratio

    | • | Annual incentive bonus target (i.e., STIP award); and |

  148. Chief Executive Officer Pay Ratio

    | • | Grant date fair value of equity awards (or long-term cash compensation award) granted during fiscal year. |

  149. Chief Executive Officer Pay Ratio

    Our calculation includes all employees in the United States, Belgium, Canada, China, Finland, France and United Kingdon, as of December 31, 2023. We applied U.S. exchange rates to the compensation elements paid in non-U.S. dollars.
