TO THE SHAREHOLDERS OF INTERDIGITAL, INC.:

We are pleased to invite you to attend our 2024 annual meeting of shareholders, which will be held on Wednesday, June 5, 2024, at 2:00 PM Eastern Time. This year’s annual meeting will be held as a virtual meeting. You will be able to attend and participate in the annual meeting online via a live webcast by visiting www.virtualshareholdermeeting.com/IDCC2024. In addition to voting by submitting your proxy prior to the annual meeting, you also will be able to vote your shares electronically during the annual meeting.

4. Such other business as may properly come before the annual meeting.

We are pleased to be using the Securities and Exchange Commission rules that allow companies to furnish proxy materials to their shareholders primarily over the Internet. We believe that this process expedites shareholders’ receipt of the proxy materials, lowers the costs of the annual meeting and helps to conserve natural resources. We also believe that hosting a virtual meeting enables participation by more of our shareholders in our annual meeting while lowering the cost of conducting the meeting. Shareholders attending the virtual meeting will be afforded substantially the same rights and opportunities to participate as they would at an in-person meeting. On or about April 23, 2024, we began mailing our shareholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our 2024 proxy statement and 2023 annual report, and how to vote online.

Your prompt response is necessary to ensure that your shares are represented at the annual meeting.

If you are a shareholder who holds stock in a brokerage account (a “street name” holder), you will receive instructions from the holder of record, which you must follow in order for your shares to be voted. Certain of these institutions offer Internet and telephone voting.

IF YOU PLAN TO ATTEND THE ANNUAL MEETING:

PROXY STATEMENT

This proxy statement contains information relating to our annual meeting of shareholders to be held on Wednesday, June 5, 2024, at 2:00 PM Eastern Time, and at any postponements or adjournments thereof. This year’s annual meeting of shareholders will be held as a virtual meeting.

You will be able to attend and participate in the annual meeting online via a live webcast by visiting www.virtualshareholdermeeting.com/IDCC2024. In addition to voting by submitting your proxy prior to the annual meeting, you also will be able to vote your shares electronically during the annual meeting. Your proxy for the annual meeting is being solicited by our Board of Directors (the “Board”).

INTERNET AVAILABILITY OF PROXY MATERIALS

As permitted by Securities and Exchange Commission (“SEC”) rules, we are making this proxy statement and our annual report available to our shareholders primarily via the Internet, rather than mailing printed copies of these materials to each shareholder. We believe that this process will expedite shareholders’ receipt of the proxy materials, lower the costs of the annual meeting and help to conserve natural resources. On or about April 23, 2024, we began mailing to each shareholder (other than those who previously requested electronic delivery of all materials or previously elected to receive delivery of a paper copy of the proxy materials) a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access and review the proxy materials, including our proxy statement and our annual report, on the Internet and how to access an electronic proxy card to vote on the Internet or by telephone. The Notice also contains instructions on how to receive a paper copy of the proxy materials. If you receive the Notice by mail, you will not receive a printed copy of the proxy materials unless you request one. If you receive the Notice by mail and would like to receive a printed copy of our proxy materials, please follow the instructions included in the Notice.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Shareholders

to be Held on June 5, 2024:

The Notice of Meeting and Proxy Statement and 2023 Annual Report are available at

http://ir.interdigital.com/FinancialDocs.

ABOUT THE ANNUAL MEETING AND VOTING

What is the purpose of the annual meeting?

At our annual meeting, shareholders will act upon the matters outlined in the Notice provided with this proxy statement, including the election of directors, the advisory resolution to approve executive compensation, the ratification of the appointment of our independent registered public accounting firm, and such other business as may properly come before the annual meeting.

Who may attend the annual meeting?

You are entitled to participate in the annual meeting only if you were a shareholder of record as of the close of business on April 10, 2024 or if you hold a valid proxy for the annual meeting. As noted above, this year’s annual meeting will be held as a virtual meeting that you may attend online via a live webcast by visiting

3

www.virtualshareholdermeeting.com/IDCC2024. Shareholders attending the virtual meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting.

In order to attend and participate in the annual meeting, you will need to visit www.virtualshareholdermeeting.com/IDCC2024 and follow the instructions that are included in the Notice, on your proxy card or in the instructions accompanying your proxy materials. You will be required to complete an online check-in process, for which you will need the 16-digit control number provided on your Notice, your proxy card or the instructions accompanying your proxy materials. If you do not have your control number, you will not be able to join the annual meeting, vote at the annual meeting or ask questions. Online check-in will begin at 1:30 PM Eastern Time, and the annual meeting will begin promptly at 2:00 PM Eastern Time. Please allow sufficient time to complete the online check-in process.

Instructions on how to attend and participate via the Internet, including how to demonstrate proof of stock ownership and how to obtain any information you may need, are posted at www.virtualshareholdermeeting.com/IDCC2024.

Who is entitled to vote at the annual meeting?

Only shareholders of record at the close of business on April 10, 2024, the record date, are entitled to receive notice of, and to vote at, the annual meeting. If you were a shareholder on that date, you will be entitled to vote all of the shares of common stock that you held on that date at the annual meeting, or any postponements or adjournments of the annual meeting. There were 25,366,746 shares of our common stock outstanding on the record date.

What are the voting rights of the holders of the company’s common stock?

Each share of our common stock outstanding on the record date will be entitled to one vote on each director nominee and one vote on each other matter considered at the annual meeting.

What constitutes a quorum?

A quorum is the minimum number of our shares of common stock that must be represented at a duly called meeting, which includes participation by electronic means such as a live webcast, or by proxy in order to conduct business legally at such meeting. For the annual meeting, the presence, live at the meeting or by proxy, of the holders of a majority of the shares entitled to vote will be considered a quorum. If you are a registered shareholder, voting by Internet or telephone or, if you requested a paper copy of the proxy materials, by mail, or attendance at the annual meeting, will cause you to be counted in the determination of a quorum. If you are a street name shareholder, your broker or other nominee will vote your shares pursuant to your instructions, and such shares will count in the determination of a quorum. If you do not provide any specific voting instructions to your broker or other nominee, your shares will still count for purposes of attaining a quorum, so long as you provide voting instructions for at least one matter or your broker or other nominee votes with respect to a matter for which they do not require your instructions, such as the ratification of the appointment of our independent registered public accounting firm.

How do I vote?

If you are a registered shareholder, you may vote by Internet or telephone by following the instructions in the Notice. If you requested a paper copy of the proxy materials, you also may submit your proxy by mail by following the instructions included with your proxy card. The deadline for submitting your proxy by Internet or telephone is 11:59 PM Eastern Time on June 4, 2024. The designated proxy will vote according to your instructions. If you attend the live webcast of the annual meeting you also will be able to vote your shares electronically at the meeting up until the time the polls are closed.

4

If you are a street name holder, your broker or nominee firm is the legal, registered owner of the shares, and it may provide you with a Notice. Follow the instructions on the Notice to access our proxy materials and vote or to request a paper or email copy of our proxy materials. If you receive these materials in paper form, the materials include a voting instruction card so that you can instruct your broker or nominee how to vote your shares. Please check your Notice or voting instruction card or contact your broker or other nominee to determine whether you will be able to deliver your voting instructions by Internet or telephone in advance of the meeting and whether, if you attend the live webcast of the annual meeting, you will be able to vote your shares electronically at the meeting up until the time the polls are closed.

If you own shares through a retirement or savings plan or other similar plan, you may submit your voting instructions by Internet, telephone or mail by following the instructions included with your voting instruction card. The deadline for submitting your voting instructions by Internet or telephone is 11:59 PM Eastern Time on May 30, 2024. The trustee or administrator of the plan will vote according to your instructions and the rules of the plan.

If you sign and submit your proxy without specifying how you would like your shares voted, your shares will be voted in accordance with the Board’s recommendations specified below under “What are the Board’s recommendations?” and in accordance with the discretion of the proxy holders with respect to any other matters that may be voted upon at the annual meeting.

Even if you plan to attend the annual meeting, we recommend that you also submit your proxy card or vote by Internet or telephone by the applicable deadline so that your vote will be counted if you later decide not to attend the meeting.

Can I change my vote after I return my proxy or voting instruction card?

If you are a registered shareholder, you may revoke or change your vote at any time before the proxy is voted by filing with our Corporate Secretary either a written notice of revocation or a duly executed proxy bearing a later date. If you attend the live webcast of the annual meeting you may revoke your proxy or change your proxy vote by voting electronically at the meeting. Your attendance at the annual meeting will not by itself revoke a previously granted proxy.

If your shares are held in street name or you hold shares through a retirement or savings plan or other similar plan, please check your voting instruction card or contact your broker, nominee, trustee or administrator to determine whether you will be able to revoke or change your vote.

Will my vote be confidential?

It is our policy to maintain the confidentiality of proxy cards, ballots and voting tabulations that identify individual shareholders except as might be necessary to meet any applicable legal requirements and, in the case of any contested proxy solicitation, as might be necessary to allow proper parties to verify proxies presented by any person and the results of the voting.

What are the Board’s recommendations?

The Board recommends that you vote:

• For election of each of the director nominees named in this proxy statement (see Proposal 1);

• For the advisory resolution to approve executive compensation (see Proposal 2); and

• For ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2024 (see Proposal 3).

5

What vote is required to approve each proposal?

Election of directors. We have adopted majority voting in uncontested director elections. Accordingly, under our articles of incorporation and bylaws, director nominees must receive the affirmative vote of a majority of the votes cast in order to be elected. A majority of the votes cast means that the number of votes cast “for” a director nominee must exceed the number of votes cast “against” that nominee. Abstentions, while included for purposes of attaining a quorum, will have no effect on the outcome of director elections. Under Pennsylvania law and our articles of incorporation and bylaws, an incumbent director who does not receive the votes required to be re-elected remains in office until his or her successor is elected and qualified, thereby continuing as a “holdover” director. Under the director resignation policy in our corporate governance principles, a director who is not re-elected must tender his or her resignation to the Nominating and Corporate Governance Committee of the Board, which will make a recommendation to the Board as to whether or not the resignation offer should be accepted. In deciding whether to accept the resignation offer, the Board will consider the recommendation of the Nominating and Corporate Governance Committee as well as any additional information and factors that the Board believes to be relevant. The Board will act on the Nominating and Corporate Governance Committee’s recommendation within ninety (90) days following certification of the election results.

Advisory resolution to approve executive compensation. The affirmative vote of a majority of the votes cast is required for approval. Because the vote is advisory, it will not be binding on the Board or the company. Abstentions, while included for purposes of attaining a quorum, will have no effect on the outcome of the proposal.

Ratification of the appointment of PricewaterhouseCoopers LLP. The affirmative vote of a majority of the votes cast is required for ratification. Abstentions, while included for purposes of attaining a quorum, will have no effect on the outcome of the proposal. Ratification of the appointment of our independent registered public accounting firm is not legally required. The Board asks shareholders to ratify the appointment as a matter of good corporate governance. If shareholders do not ratify the appointment, the Audit Committee of the Board will consider whether it is appropriate to select another independent registered public accounting firm in future years.

What is a “broker non-vote”?

If you hold your shares in street name through a broker or other nominee, your broker or nominee may not be permitted to exercise voting discretion with respect to non-routine matters if you do not provide voting instructions. “Broker non-votes” are shares held in street name by a broker or nominee that is present or represented by proxy at a shareholders meeting to vote, but for which the beneficial owner has not provided the record holder with instructions on how to vote on a non-routine matter. For the annual meeting, if you do not provide specific voting instructions, your broker or nominee may not exercise voting discretion with respect to Proposal 1, the election of directors or Proposal 2, the advisory vote on executive compensation. If you do not provide specific voting instructions, your broker or nominee may exercise voting discretion with respect to Proposal 3, the ratification of the appointment of the company’s independent registered public accounting firm. Therefore, we do not expect any broker non-votes to occur for Proposal 3, but broker-non-votes may occur for Proposals 1 and 2. Broker non-votes will be counted for the purposes of calculating whether a quorum is present at the annual meeting but will have no effect on the outcome of the vote.

How do I ask questions at the annual meeting?

We have designed the virtual annual meeting to provide substantially the same opportunities to participate as shareholders would have at an in-person meeting. The virtual annual meeting format allows shareholders to communicate with the company during the annual meeting so they can ask questions of our management and Board, as appropriate. If you wish to submit a question during the annual meeting, you may do so by logging into the virtual meeting platform at www.virtualshareholdermeeting.com/IDCC2024, typing your question into the “Ask a Question” field and clicking “Submit.”

6

We reserve the right to exclude questions regarding topics that are not pertinent to meeting matters or company business or are inappropriate. If we receive substantially similar questions, we may group such questions together and provide a single response to avoid repetition. Any questions that are appropriate and pertinent to the annual meeting will be answered in the live Q&A session during the annual meeting, subject to time constraints. Any such questions that cannot be answered during the annual meeting due to time constraints will be posted and answered on our Investor Relations website, http://ir.interdigital.com, as soon as practicable after the annual meeting.

Additional information regarding the ability of shareholders to ask questions during the annual meeting, related rules of conduct, and other materials for the annual meeting will be available during the annual meeting at www.virtualshareholdermeeting.com/IDCC2024.

How do I access technical support during the annual meeting?

If you encounter any difficulties accessing the virtual annual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual meeting login page for assistance. Technical support will be available beginning approximately 15 minutes prior to the start of the annual meeting through its conclusion. Additional information regarding matters addressing technical and logistical issues, including technical support during the annual meeting, will be available at www.virtualshareholdermeeting.com/IDCC2024. The virtual annual meeting platform is fully supported across browsers (Edge, Firefox, Chrome, and Safari) and devices (desktops, laptops, tablets, and smartphones) running the most updated version of applicable software and plugins. You should ensure that you have a strong internet connection if you intend to attend and/or participate in the annual meeting.

GOVERNANCE OF THE COMPANY

Where can I find information about the governance of the company?

The company has adopted corporate governance principles that, along with the charters of each of the Board committees, provide the framework for the governance of the company. The Nominating and Corporate Governance Committee is responsible for annually reviewing the principles and recommending any proposed changes to the Board for approval. A copy of our corporate governance principles is posted on our website at http://ir.interdigital.com under the IR menu heading “ESG – Governance,” along with the charters of each of our Board committees and other information about our governance practices. We will provide to any person without charge a copy of any of these documents upon written request to our Corporate Secretary at our principal executive offices: InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, Delaware 19809-3727.

Code of Ethics

Does the company have a code of ethics?

We have adopted a Code of Ethics that applies to all directors, officers, employees and consultants, including our principal executive, financial and accounting officers or persons performing similar functions. The Audit Committee is responsible for annually reviewing the Code of Ethics and recommending any proposed changes to the Board for approval. A copy of our Code of Ethics is available on the company’s website at http://ir.interdigital.com under the IR menu heading “ESG – Governance – Governance Documents.” We intend to disclose future amendments to certain provisions of the Code of Ethics, or any waiver of such provisions granted to executive officers and directors, on the website within four business days following the date of such amendment or waiver. We will provide to any person without charge a copy of our Code of Ethics upon written request to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, Delaware 19809-3727.

Director Independence

Which directors are considered independent, and how does the Board determine their independence?

Each year, prior to the annual meeting of shareholders, the Board reviews and assesses the independence of its directors and makes a determination as to the independence of each director. During this review, the Board considers transactions and relationships between each director or any member of his or her immediate family and our company and its subsidiaries and affiliates. As a result of these reviews, the Board affirmatively determined that each of Mses. Joan H. Gillman and Jean F. Rankin, Messrs. Derek K. Aberle, Samir Armaly, S. Douglas Hutcheson, John A. Kritzmacher and John D. Markley, Jr. and Dr. Pierre-Yves Lesaicherre are “independent” under applicable SEC rules and listing standards of the Nasdaq Stock Market.

Board Leadership

Who is the Chairman of the Board, and are the positions of Chairman of the Board and Chief Executive Officer separated?

Mr. Hutcheson, who is an independent director, has served as Chairman of the Board since June 2015. The Board has a general policy that the positions of Chairman of the Board and Chief Executive Officer should be held by separate persons as an aid in the Board’s oversight of management. This policy is affirmed in the Board’s published corporate governance principles, which mandate that the Chairman of the Board be an independent director. The Board believes that this leadership structure is appropriate for the company at this time because of the advantages of having an independent chairman for matters such as communications and relations between the Board and the Chief Executive Officer and other senior management, reaching consensus on company strategies and policies, and facilitating robust Board, committee and Chief Executive Officer evaluation processes. The

8

Board periodically reviews its leadership structure to determine whether it is appropriate given the specific characteristics and circumstances of the company.

Board Oversight of Risk

What is the Board’s role in risk oversight?

The Board is responsible for overseeing the major risks facing the company and the company’s enterprise risk management (“ERM”) efforts. The Board has delegated to the Audit Committee primary responsibility for overseeing and monitoring these efforts. Under its charter, the Audit Committee is responsible for discussing with management and the company’s independent registered public accounting firm significant risks and exposures relating to the company’s quarterly and annual financial statements and assessing management’s steps to mitigate them, and for reviewing corporate insurance coverage and other risk management programs, including those related to cybersecurity, information and technology security and data privacy related risks. At least quarterly, the Audit Committee receives presentations and reports directly from the company’s Chief Legal Officer, who leads the company’s day-to-day ERM efforts. The Audit Committee briefs the Board on the company’s ERM activities as part of its regular reports to the Board on the activities of the committee, and the Chief Legal Officer also periodically delivers presentations and reports to the full Board as appropriate.

Environmental, Social and Governance Matters

Our Nominating and Corporate Governance Committee has primary oversight over environmental, social and governance (“ESG”) matters, which it exercises in conjunction with the other committees of the Board. In addition, our Chief Financial Officer oversees a committee of senior executives that steers the process of setting purpose, strategies, policies and goals related to economic, environmental and social topics. We are committed to sustainable business principles, to thinking long-term and to making strategic decisions that adhere to our mission and values.

In 2023, we continued our efforts to improve our company-wide ESG performance. This included furthering our efforts to track and reduce our carbon footprint. We were able to increase our renewable energy footprint to 52% of our data center consumption from 43% in 2022. Globally, 31% of our total energy consumption came from renewable sources in 2023. We also committed to relocating our office in London and reassigning certain employees in New York to our new Melville office to reduce our overall global office CO2 emissions from our commuting workforce. As part of these efforts, we opened our new “green” office space at our largest facility in Rennes, France in the second quarter of 2023. This new facility is BREEAM certified for sustainability, allowing us to reduce our annual energy consumption in Rennes by 50%, exceeding the estimated goal of 25% reduction with this new office.

We have also made a commitment to Board diversity, as described further in “Board Structure and Committee Membership—Nominating and Corporate Governance Committee” below. Further, we believe that maintaining a diverse, equitable and inclusive workforce is critical to our ability to succeed in the global marketplace. In recent years we have invested in our talent acquisition, talent development, and succession planning efforts as a means to diversify our workforce. We have continually provided historically underrepresented and female leaders the opportunity to attend targeted world-class external development programs that speak to the unique experiences these employees can face in the workplace while investing in their continued growth both personally and professionally. In addition, core principles of our culture of inclusion are reflected in the all-employee training programs we offer on our policies against harassment and discrimination of any kind. In 2022 we launched our Diversity, Equity & Inclusion (“DEI”) taskforce, an employee-led team focused on supporting the execution of InterDigital’s DEI strategy.

We maintain a Sustainability webpage at https://ir.interdigital.com/esg/overview/ and intend to regularly communicate our goals and progress on various ESG matters. The information on our sustainability website is not incorporated by reference into, and does not form part of, this proxy statement.

Board Structure and Committee Membership

What is the size of the Board, and how often are directors elected?

The Board currently has nine directors. All directors are subject to election for one-year terms at each annual meeting of shareholders.

How often did the Board meet during 2023?

The Board met five times during 2023. Each director is expected to attend each meeting of the Board and those committees on which he or she serves. Each director attended at least 75% of the aggregate of all Board meetings and meetings of committees on which the director served during 2023. We typically schedule one of the meetings of the Board on the day immediately preceding or following our annual meeting of shareholders, and it is the policy of the Board that directors are expected to attend our annual meeting of shareholders absent unusual circumstances. All nine of our directors attended the 2023 annual meeting of shareholders.

What are the roles of the primary Board committees?

The Board has standing Audit, Human Capital (formerly Compensation), Finance, and Nominating and Corporate Governance Committees. The Board also forms additional standing or ad hoc committees from time to time. Each of the Audit, Human Capital, and Nominating and Corporate Governance Committees is composed entirely of independent directors, as determined by the Board in accordance with applicable SEC rules and listing standards of the Nasdaq Stock Market. Mr. Chen does not serve on any of the committees but generally attends each committee meeting. Each of the Board committees operates under a written charter that has been approved by the Board. The following table provides information about the current membership of the committees and the number of meetings each committee held in 2023.

Audit Committee

The Audit Committee assists the Board in fulfilling its oversight responsibilities relating to the company’s corporate accounting, financial reporting practices, audits of its financial statements and compliance with applicable requirements regarding the maintenance of accurate books and records. Among other things, the committee:

• Reviews the company’s annual and quarterly financial statements and discusses them with management and the company’s independent registered public accounting firm;

• Appoints, compensates, retains, evaluates, oversees the work of (including resolution of disagreements between management and the company’s independent registered public accounting firm regarding

10

financial reporting) and, if deemed appropriate, replaces the company’s independent registered public accounting firm;

• Reviews and discusses the company’s practices with respect to risk assessment and risk management, including but not limited to the specific risks associated with the matters set forth for Audit Committee oversight in the committee’s charter, and discusses with management and the company’s independent registered public accounting firm significant risks and exposures and assesses management’s steps to minimize them;

• Receives from the company’s independent registered public accounting firm reports required by applicable SEC rules and professional standards, including reviewing and discussing with the company’s independent registered public accounting firm the matters required to be discussed under applicable requirements of the Public Company Accounting Oversight Board and the SEC;

• Reviews the adequacy and effectiveness of the company’s system of internal control over financial reporting and disclosure controls and procedures;

• Reviews and approves, at least annually, the management, scope, plans, budget, staffing and relevant processes and programs of the company’s internal audit function;

• Establishes and oversees procedures for receiving and handling reports of potential misconduct, including violations of law or the company’s Code of Ethics and complaints received by the company regarding accounting, internal accounting controls, auditing or federal securities law matters and the confidential, anonymous submission by the company’s employees of concerns regarding questionable accounting, auditing or federal securities law matters;

• Oversees the company’s other compliance policies and programs, including the implementation and effectiveness of the company’s Code of Ethics;

• Oversees the company’s compliance with data privacy rules and regulations;

• Oversees and reviews the Company’s cybersecurity, information and technology security and data privacy frameworks, policies, programs, opportunities, and risk profile; and the Company’s business continuity and disaster recovery plans and capabilities and the effectiveness of the Company’s escalation procedures;

• Oversees and monitors the company’s ERM efforts; and

• Reviews and provides guidance to the Board with respect to tax planning, corporate insurance coverage and implementation of new or revised accounting or auditing standards or regulatory changes.

All of the Audit Committee members are financially literate. The Board has determined that three of its members (Messrs. Hutcheson, Kritzmacher and Markley), including one of the current members of the Audit Committee (Mr. Kritzmacher), qualify as “audit committee financial experts” within the meaning of applicable SEC regulations and thereby meet the “financial sophistication” requirements of the Nasdaq listing rules. Mr. Kritzmacher acquired his expertise primarily through his prior experience as a chief financial officer of a publicly traded company.

Human Capital Committee

The Human Capital Committee assists the Board in discharging its responsibilities relating to the compensation of the Chief Executive Officer and other executive officers, develops, reviews and approves the principles guiding the company’s compensation policies, oversees the company’s compensation-related policies and programs and the level of awards to employees, and assists the Board and the Chairman of the Board in succession planning. Among other things, the committee:

• Reviews and approves the corporate goals and objectives relevant to the compensation of the company’s Chief Executive Officer and other executive officers, evaluates their performance in light of

11

such goals and objectives and, based on its evaluations and appropriate recommendations, reviews and approves the compensation of the Chief Executive Officer and other executive officers, including approving the grant of equity awards, each on an annual basis;

• Assists the Board in developing and evaluating potential candidates for executive positions and oversees and annually reviews the development of executive succession plans;

The Human Capital Committee may delegate authority to the committee chair or a sub-committee, as the committee may deem appropriate, subject to such ratification by the committee as the committee may direct. The Human Capital Committee also may delegate to one or more officers of the company the authority to make grants of stock options or other supplemental awards at specified levels, under specified circumstances, to eligible employees who are not executive officers of the company, subject to reporting to and such ratification by the committee as the committee may direct.

Human Capital Committee Interlocks and Insider Participation

Ms. Rankin and Messrs. Aberle, Hutcheson and Markley served on the Human Capital Committee during all of 2023. No director serving on the Human Capital Committee during any part of 2023 was, at any time either

12

during or before such fiscal year, an officer or employee of the company or any of its subsidiaries. In addition, none of the company’s executive officers has served as a member of a board of directors or a compensation committee, or other committee serving an equivalent function, of any other entity, one of whose executive officers served as a member of the company’s Board or Human Capital Committee.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee assists the Board in identifying qualified individuals to become Board and committee members, considers matters of corporate governance and assists the Board in evaluating the Board’s effectiveness. Among other things, the committee:

• Develops and recommends to the Board criteria for Board membership (including issues of character, integrity, judgement, diversity, independence, skills, education, business acumen, business experience, understanding of the company’s business and the like);

• Identifies, reviews the qualifications of, and recruits candidates for election to the Board and to fill vacancies or new positions on the Board;

• Assesses the contributions of incumbent directors in determining whether to recommend them for re-election to the Board;

• Reviews candidates recommended by the company’s shareholders for election to the Board;

• Assesses the independence of directors, director nominees and director candidates under applicable standards, including any heightened independence requirements applicable to Audit and Human Capital Committee members, and recommends independence determinations to the Board;

• Reviews annually the company’s corporate governance principles and recommends changes to the Board as appropriate;

• Assists the Board in ensuring proper attention and effective response to shareholder concerns regarding corporate governance;

• Assists and generally advises the Board on ESG matters (except as may be specifically retained by the Board or delegated to other Board committees), including overseeing the Company’s ESG strategy, and related goals and policies, and periodically reviews with management the Company’s progress towards the achievement of such strategy and goals, and reviews and discusses with management the Company’s material ESG disclosures, in each case in coordination with the other committees of the Board and, as appropriate, makes recommendations on such matters to the full Board;

• Reviews and makes recommendations to the Board with respect to the Board’s and each committee’s size, structure, composition and functions;

• Oversees the process for evaluating the Board and its committees; and

• Periodically reviews the Board’s leadership structure and recommends changes to the Board as appropriate.

The committee will consider director candidates recommended by our shareholders. Shareholders recommending candidates for consideration by the Nominating and Corporate Governance Committee should send their recommendations to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, Delaware 19809-3727. The recommendation must include the candidate’s name, biographical data and qualifications and a written statement from the candidate of his or her consent to be named as a candidate and, if nominated and elected, to serve as a director. The committee may ask candidates for additional information as part of the process of assessing a shareholder-recommended director candidate. The committee evaluates director candidates recommended by shareholders based on the same criteria used to evaluate candidates from other sources.

13

We are committed to having at least two diverse directors, including at least one who self-identifies as female and at least one who self-identifies as either LGBTQ+ or part of a historically underrepresented group. The Board currently includes four diverse directors, including two who self-identify as female and two who self-identify as part of a historically underrepresented group. As described in our corporate governance principles, with respect to diversity, the Nominating and Corporate Governance Committee may consider such factors as gender, race, ethnicity, differences of perspective, professional background, experience at policy-making levels in business, finance and technology and other areas, education, skill and other individual qualities and attributes that are relevant to the company’s global activities and contribute to Board heterogeneity. The selection criteria for director candidates also include the following:

• Each director should be an individual of the highest personal and professional ethics, integrity and values.

• Each director should be committed to representing the long-term interests of the company’s shareholders and demonstrate a commitment to long-term service on the Board.

• Each director should have an inquisitive and objective perspective, practical wisdom and mature judgment.

The company is committed to ensuring that other existing and future anticipated commitments of its directors do not materially interfere with his or her service as a director. Accordingly, our corporate governance principles prohibit any director from serving on the boards of more than four other public companies, unless such director is an executive officer of a public company, and in such cases, such director may not serve on the boards of more than two other public companies. In addition, prior to accepting service on the board of any other company, a director must notify the Board’s Chairman and the Nominating and Corporate Governance Committee, and service on the board or a committee of any other organization should be consistent with the company’s conflict of interest policies.

The Nominating and Corporate Governance Committee periodically evaluates the composition of the Board to assess the skills and experience that are currently represented on the Board, as well as the skills and experience that the Board will find valuable in the future. This evaluation of the Board’s composition enables the Board to update the skills and experience it seeks in the Board as a whole, and in individual directors, as the company’s needs evolve and change over time and to assess the effectiveness of efforts at pursuing diversity. See “Proposals to be Voted On – Election of Directors (Proposal 1)” for a summary of the qualifications, experience and other relevant attributes of the directors nominated for election at this year’s annual meeting.

The Nominating and Corporate Governance Committee has previously retained and may in the future retain a search firm to help identify director prospects, perform candidate outreach, assist in reference checks, and provide other related services. The recruiting process typically involves either the search firm or a member of the Nominating and Corporate Governance Committee contacting a prospect to gauge his or her interest and availability. A candidate will then meet with several members of the Board, including our Chief Executive Officer. At the same time, the Nominating and Corporate Governance Committee or other Board members, as appropriate, and the search firm will contact references for the prospect. A background check is completed before the Board approves any final recommendation from the committee to appoint a candidate to the Board.

Finance Committee

The primary role of the Finance Committee is to monitor and provide guidance to the company’s management team and recommend actions to the Board with respect to certain investment and financial policies and strategies and the capital structure of the company, and to approve certain investment and divestment activities of the company and funding for certain affiliated entities of the company. Among its specific duties and responsibilities, the committee:

• Reviews and provides guidance to the Board with respect to:

• the company’s capital structure, including the issuance of debt, equity or other securities;

14

• shareholder distributions, including share repurchases and dividends;

• cash management investment policies;

• foreign currency investment policies; and

• on a periodic basis, the integrity of the company’s financial models;

• Approves minority investments in other companies by the company;

• Approves divestments of minority equity interests in other companies by the company; and

• Approves the establishment of non-core operating businesses as entities partially owned by the company, including approval of contributions to such entities and the ownership structure of such entities.

The committee may delegate authority to the committee chair or a sub-committee, as the committee may deem appropriate, subject to such ratification by the committee as the committee may direct.

Board Self-Evaluation Process

How does the Board evaluate its effectiveness?

The Nominating and Corporate Governance Committee establishes and oversees the annual self-assessment process that the Board uses to evaluate its effectiveness and identify opportunities for improvement. Each director is asked to provide an assessment of the Board’s effectiveness in several areas, including information and planning, content and conduct of meetings, and accountability. Once the responses are compiled, the Nominating and Corporate Governance Committee, in conjunction with the Board’s Chairman, identifies specific areas of improvement for the following year. The assessment also asks each director their opinion of the Board’s progress in these identified areas.

Communications with the Board

How can shareholders communicate with the Board?

Shareholders and other parties interested in communicating directly with any individual director, including the Chairman, the Board as a whole, or the non-employee directors as a group may do so by writing to Investor Relations, InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, Delaware 19809-3727, or by sending an email to InvestorRelations@InterDigital.com. Each communication should set forth (i) the name and address of the shareholder as it appears on the company’s books, and, if the company’s common stock is held by a nominee, the name and address of the beneficial owner of the company’s common stock, and (ii) the class and number of shares of the company’s common stock that are owned of record by the record holder and beneficially by the beneficial owner. Our Investor Relations department reviews all such correspondence and, in consultation with appropriate directors and/or the company’s Legal department as necessary, generally screens communications from shareholders to identify communications that (a) are solicitations for products and services, (b) relate to matters of a personal nature not relevant for the company’s shareholders to act on or for the Board to consider, or (c) are matters that are of a type that render them improper or irrelevant to the functioning of the Board or the company. The Investor Relations department regularly forwards to the Board or specified director(s) a summary of all relevant correspondence and copies of all correspondence that deal with the functions of the Board or its committees or that otherwise require their attention. Directors may, at any time, review a log of all correspondence we receive that is addressed to members of the Board and request copies of any such correspondence.

15

Communications About Accounting Matters

How can individuals report concerns relating to accounting, internal control, auditing or federal securities law matters?

Concerns relating to accounting, internal control, auditing or federal securities law matters may be submitted by writing to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, Delaware 19809-3727. All correspondence will be brought to the attention of the chair of the Audit Committee and handled in accordance with procedures established by the Audit Committee with respect to these matters.

DIRECTOR COMPENSATION

How are directors compensated?

During 2023, our non-employee directors were paid annual cash retainers for their Board and committee participation as follows:

	Chair			Member
Board	$	75,000	*	$	65,000	*
Audit Committee	$	30,000		$	12,000
Human Capital Committee	$	20,000		$	10,000
Nominating and Corporate Governance Committee	$	15,000		$	7,500
Finance Committee	$	15,000		$	7,500

* The annual cash retainer paid to the Chairman of the Board is in addition to the annual cash retainer paid to all non-employee Board members.

All cash retainers are generally paid quarterly in arrears and based upon service for a full year, and prorated payments are made for service of less than a full year.

The compensation program is designed to compensate each non-employee director for participating in up to ten Board meetings per year and up to ten meetings per year for each standing committee on which the non-employee director serves. Additional compensation is paid to each non-employee director for participating in meetings during the Board term (which runs from annual meeting date to annual meeting date) in excess of these thresholds, as follows: $4,000 for each additional Board meeting and $1,000 for each additional committee meeting.

In addition, non-employee directors are paid a per diem fee of $1,000 for attendance at or participation in events, conferences or meetings, in their capacity as a director, at the request of the company’s senior management, provided that such attendance or participation requires a significant time commitment and would be considered outside of the director’s typical Board and/or committee duties. Any per diem fee payments are subject to the approval of the Human Capital Committee.

For his or her service during the 2023-2024 Board term, each non-employee director received a restricted stock unit (“RSU”) award in an amount approximately equal in value to $187,500 that vests in full one year from the grant date. Upon his or her initial appointment to the Board, new non-employee directors receive a pro-rated RSU award for his or her partial service during the then-current Board term, as well as an initial appointment award of RSUs in an amount equal in value to $150,000 that vests in full one year from the grant date. The number of RSUs granted is calculated using the closing stock price of the company’s common stock on the date of grant. The vesting of RSU awards may be deferred. Except in certain limited circumstances, an election to defer must be made in the calendar year preceding the year that the award is made. Unvested time-based RSUs and deferred RSUs accrue dividend equivalents, which are paid in the form of additional shares of stock at the time, and only to the extent, that the awards vest or at the end of the deferral period, as applicable.

To align the interests of non-employee directors and executives with those of our shareholders, the company has adopted stock ownership guidelines. The stock ownership guidelines applicable to the non-employee directors are set at a target of the lesser of (a) company stock valued at an amount equal to five times the annual cash retainer for directors of $65,000 or (b) 6,000 shares/units of the company’s stock. Qualifying stock includes shares of common stock and restricted stock. For purposes of calculating the value of company stock holdings, each share or other qualifying stock unit is priced at a price per share/unit equal to the average closing stock 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 stock price is calculated annually on the date of the company’s annual meeting of shareholders. Any director who has not reached or fails to maintain the target ownership level must retain at least

17

50% of any after-tax shares derived from vested RSUs until the target ownership level is met. A director may not make any disposition of shares that results in his or her holdings falling below the target ownership level without the express approval of the Human Capital Committee. Directors have five years to reach their target ownership level. As of March 31, 2024, all non-employee directors had either met their target ownership level or had more time to do so, and all directors who had not yet met their target ownership level were in compliance with the guidelines.

The company’s directors are also eligible to participate in the company’s nonqualified deferred compensation plan by deferring receipt of their annual Board fees. None of the directors elected to defer any of their 2023 Board fees. For more information about the deferred compensation plan, see “Executive Compensation – Nonqualified Deferred Compensation.”

The following table sets forth the compensation paid to each person who served as a director of the company in 2023 for their service in 2023. Directors who also serve as employees of the company do not receive any additional compensation for their services as a director.

(Proposal 1)

Description

Which directors are nominated for election?

Mses. Joan H. Gillman and Jean F. Rankin, Messrs. Samir Armaly, Derek K. Aberle, Liren Chen, S. Douglas Hutcheson, John A. Kritzmacher and John D. Markley, Jr. and Dr. Pierre-Yves Lesaicherre are recommended by the Nominating and Corporate Governance Committee and nominated by the Board for election at the 2024 annual meeting, each to serve a one-year term until our annual meeting in 2025 and until his or her successor is elected and qualified.

Set forth below is biographical information about the nine nominees and other information about their skills and qualifications that contribute to the effectiveness of the Board. All of the nominees’ current terms of office expire at the 2024 annual meeting.

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

20

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.

John A. Kritzmacher, 63, has been a director of the company since June 2009. From 2013 to 2021, Mr. Kritzmacher served as Executive Vice President and Chief Financial Officer of John Wiley & Sons, Inc., a global provider of research communications and education services. From October 2012 through February 2013, Mr. Kritzmacher served as Senior Vice President Business Operations and Organizational Planning at WebMD Health Corp., a leading provider of health information services, where Mr. Kritzmacher was responsible for

21

leading a major restructuring initiative. Previously, Mr. Kritzmacher served as Executive Vice President and Chief Financial Officer of Global Crossing Limited, a global provider of IP-based telecommunications solutions, from October 2008 to October 2011, when Global Crossing was acquired by Level 3 Communications, Inc. Prior to that, Mr. Kritzmacher rose through a variety of positions with increasing responsibility, including Senior Vice President and Corporate Controller, during his 10 years at Lucent Technologies Inc., a provider of telecommunications systems and services, to become Chief Financial Officer in 2006. After playing a leading role in the planning and execution of Lucent’s merger with Alcatel in 2006, Mr. Kritzmacher became Chief Operating Officer of the Services Business Group at Alcatel-Lucent until joining Global Crossing in 2008. 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.

Pierre-Yves Lesaicherre, 60, has been a director of the company since June 2021. Since June 2023, Dr. Lesaicherre has been acting as the CEO and executive director of Finwave Semiconductor, Inc. Before that, he was the President, Chief Executive Officer and Director of Nanometrics Incorporated from November 2017 to October 2019. From January 2012 to February 2017, Dr. Lesaicherre was the CEO of Lumileds, an integrated manufacturer of LED components and Automotive Lighting Lamps. Prior to that, he held senior executive positions at NXP Semiconductors, from 2006 to 2012. Before NXP, Dr. Lesaicherre was with Philips Semiconductors. Dr. Lesaicherre holds an MBA with a focus on international business and strategy from INSEAD and has MS and Ph.D. degrees in Material Science from the National Polytechnic Institute of Grenoble. The Board has concluded that Dr. Lesaicherre should serve as a director of the company because of his more than 20 years of experience working in high technology industries, including in France where we have substantial operations.

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. In addition, since 2014, he has been a Managing Partner of New Amsterdam Growth Capital, an investor in communications, media and technology companies. From 1996 to 2009, he was a partner with Columbia Capital, a venture capital firm, where he served in a number of capacities including partner, venture partner and portfolio company executive. Prior to Columbia Capital, Mr. Markley served as a policy advisor at the Federal Communications Commission from 1994 to 1996, where he and his team were instrumental in developing and launching the commercial spectrum auction process. Mr. Markley has also been a director of Charter Communications, Inc., since 2009, currently serving as chair of its nominating and corporate governance committee and as a member of its audit committee. He previously served on the boards of directors of Millennial Media, Inc., from 2006 to 2014, and of BroadSoft, Inc., from 2002 until its acquisition by Cisco Systems, Inc. in February 2018. The Board has concluded that Mr. Markley should serve as a director of the company based on his private equity and operating experience and his extensive experience with communications, media and technology companies, which allow him to contribute guidance and advice relating to the development and execution of the company’s strategy and analysis of potential business opportunities. He also qualifies as an audit committee financial expert.

Jean F. Rankin, 65, has been a director of the company since June 2010. Ms. Rankin served as Executive Vice President, General Counsel and Secretary at LSI Corporation, a leading provider of innovative silicon, systems and software technologies for the global storage and networking markets, from 2007 to May 2014, when LSI was acquired by Avago Technologies Limited. In this role, she served LSI and its board of directors as Corporate Secretary, in addition to managing the company’s legal, intellectual property licensing and stock administration organizations. Ms. Rankin joined LSI in 2007 as part of the merger with Agere Systems Inc., where she served as Executive Vice President, General Counsel and Secretary from 2000 to 2007. Prior to joining Agere in 2000, Ms. Rankin was responsible for corporate governance and corporate center legal support

22

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.

Advisory Resolution to Approve Executive Compensation

(Proposal 2)

Description

We are asking shareholders to vote on an advisory resolution to approve the company’s executive compensation as reported in this proxy statement. As described below in the “Compensation Discussion and Analysis” section of this proxy statement, the Human Capital Committee has structured our executive compensation program in an effort to align management’s interests with those of its shareholders and to attract, retain and motivate talented individuals who will drive the successful execution of the company’s strategic plan. We motivate our executives primarily by “paying for performance,” or rewarding the accomplishment of individual performance and corporate goals through the use of performance-based compensation. As discussed in the “Compensation Discussion and Analysis” section of this proxy statement, the achievement of financial and strategic corporate goals, as well as departmental and individual performance, determine the short-term and long-term incentive compensation paid to our executives. Our executive compensation programs have a number of features designed to promote these objectives.

We urge shareholders to read the “Compensation Discussion and Analysis” section of this proxy statement below, which describes how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and other related compensation tables and narrative below, which provide detailed information on the compensation of our named executive officers. The Human Capital Committee and the Board believe that the policies and procedures articulated in the “Compensation Discussion and Analysis” section of this proxy statement are effective in achieving our goals and that the compensation of our named executive officers reported in this proxy statement reflects and supports these compensation policies and procedures.

The Board has adopted a policy providing for an annual advisory resolution to approve executive compensation. In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as a matter of good corporate governance, we are asking shareholders to approve the following advisory resolution at the 2024 annual meeting of shareholders:

RESOLVED, that the shareholders of InterDigital, Inc. (the “company”) approve, on an advisory basis, the compensation of the company’s named executive officers disclosed in the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables, notes and narrative in the proxy statement for the company’s 2024 annual meeting of shareholders.

This advisory resolution, commonly referred to as a “say on pay” resolution, is non-binding on the Board. Although non-binding, the Board and the Human Capital Committee will review and consider the voting results when making future decisions regarding our executive compensation program. Unless the Board modifies its policy on the frequency of future “say on pay” votes, the next “say on pay” vote will be held at the 2025 annual meeting of shareholders.

Vote Required and Board Recommendation

The affirmative vote of the majority of votes cast is required to approve this advisory resolution.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR

THE ADVISORY RESOLUTION TO APPROVE EXECUTIVE COMPENSATION.

Although ratification of the appointment of PwC is not legally required, the Board is asking the shareholders to ratify the appointment as a matter of good corporate governance. If the shareholders do not ratify the appointment, the Audit Committee will consider whether it is appropriate to select another independent registered public accounting firm in future years. Even if the shareholders ratify the appointment, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the company and its shareholders.

Representatives from PwC are expected to be present at the annual meeting, will have the opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions.

Audit Committee Pre-Approval Policy for Audit and Non-Audit Services of Independent Registered Public Accounting Firm

The Audit Committee has adopted a policy that requires the committee to pre-approve all audit and non-audit services to be performed by the company’s independent registered public accounting firm. Unless a service falls within a category of services that the Audit Committee already has pre-approved, an engagement to provide the service requires specific pre-approval by the Audit Committee. Also, proposed services exceeding pre-approved cost levels require specific pre-approval.

Consistent with the rules established by the SEC, proposed services to be provided by the company’s independent registered public accounting firm are evaluated by grouping the services and associated fees under one of the following four categories: Audit Services, Audit-Related Services, Tax Services and All Other Services. All proposed services for the following year are discussed and pre-approved by the Audit Committee, generally at a meeting or meetings that take place during the October through December time period. In order to render approval, the Audit Committee has available for reference a schedule of services and fees approved by category for the current year, and specific details of the proposed services are provided to the Audit Committee.

The Audit Committee has delegated pre-approval authority to its chair for cases where services must be expedited. In cases where the Audit Committee chair pre-approves a service provided by the independent registered public accounting firm, the chair is required to report the pre-approval decisions to the Audit Committee at its next scheduled meeting. The company’s management periodically provides the Audit Committee with reports of all pre-approved services and related fees by category incurred during the current fiscal year, with forecasts of any additional services anticipated during the year.

All of the services performed by PwC related to fees disclosed above were pre-approved by the Audit Committee.

Vote Required and Board Recommendation

The affirmative vote of the majority of votes cast at the annual meeting is required to ratify the appointment of PwC as the company’s independent registered public accounting firm for the year ending December 31, 2024.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR

REPORT OF THE AUDIT COMMITTEE

As more fully described in its charter, the Audit Committee oversees the company’s financial reporting processes on behalf of the Board. In fulfilling our oversight responsibilities, the Audit Committee reviewed and discussed with management the company’s audited consolidated financial statements for the year ended December 31, 2023, including a discussion of the acceptability and appropriateness of significant accounting principles and management’s assessment of the effectiveness of the company’s internal control over financial reporting. Management represented to us that the company’s consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States and considered appropriate in the circumstances to present fairly the company’s financial position, results of operations and cash flows. The Audit Committee also reviewed and discussed with PwC, the company’s independent registered public accounting firm, the matters required to be discussed with the independent registered public accounting firm under applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

The Audit Committee also received and reviewed the written disclosures and the letter from PwC required by applicable requirements of the PCAOB regarding PwC’s communications with the Audit Committee concerning independence and discussed with PwC their independence.

Based on the reviews and discussions with management and the independent registered public accounting firm referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in the company’s annual report on Form 10-K for the year ended December 31, 2023, and the Audit Committee retained PwC as the company’s independent registered public accounting firm for the year ending December 31, 2024.

2023 Compensation Decisions and Actions

The following are highlights of the key compensation decisions made by the Human Capital Committee for 2023:

• Increases to Base Salaries. The base salaries of certain NEOs saw modest adjustments to ensure that their base pay remained competitive. Please see “2023 Executive Compensation in Detail – Base Salaries” below for details.

• Emphasized Corporate Performance in Short Term Incentive Program (“STIP”). The 2023 STIP was designed such that baseline funding is based entirely on corporate performance, with individual performance then used as a bonus modifier. These changes were implemented in response to shareholder feedback.

• Paid STIP awards consistent with performance results. Our short-term incentives were paid according to the STIP’s formulaic funding, with no discretionary adjustment. Please see “2023 Executive Compensation in Detail – Short-Term Incentive Plan” below for details.

• Tied the majority of annual target compensation to long-term shareholder value creation. Approximately 88% of target annual CEO compensation and, on average, 79% of target annual compensation for our other NEOs, was performance-based delivered as a combination of goal-driven annual cash incentives and equity.

• Provided a majority of our executives’ long-term incentives in performance-based equity. Two-thirds of our CEO’s 2023 equity compensation was in the form of performance-based RSUs and performance-based options. The weighting of our 2023 performance-based equity awards for our other NEOs was increased to 50% in response to shareholder feedback. Please see “2023 Executive Compensation in Detail – Long-Term Compensation Program” below for details.

• Determined payout results for 2019 and 2021 Long-Term Performance Grants under the Long-Term Compensation Plan (“LTCP”). Achievement of the performance-based RSUs granted under the 2019 LTCP and the performance-based RSUs and options granted under the 2021 LTCP were earned and vested based each plan’s formulaic funding.

Shareholder Engagement and Results from 2023 Shareholder Advisory Vote on Executive Compensation

At the 2023 annual meeting of shareholders, we held an advisory vote on executive compensation. In 2023, we received shareholder support for our executive compensation programs with say on pay support of approximately 98% after receiving approximately 64% in 2022. The Human Capital Committee considers the results of the annual advisory vote on executive compensation as a strong data point in its compensation decisions and as a result, expanded its efforts to obtain feedback in the fall of 2022 and spring of 2023, resulting in changes to our compensation program that received approval in 2023.

The Human Capital Committee actively and directly seeks out feedback from shareholders regarding our executive compensation program. Specifically, in both the spring and fall of 2023, 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 two-thirds 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 2023, our investor relations team participated in six investor conferences and three non-deal roadshow events and engaged with over 125 existing and prospective institutional investors 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, ESG and executive compensation.

32

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 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 have single-trigger payout provisions in our equity award agreements.
✓   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 do not provide golden parachute tax gross-ups. ☒   We do not guarantee minimum STIP payouts.
✓   We maintain a clawback policy that complies with requirements of The Nasdaq Stock Market (“Nasdaq”) and Section 10D and Rule 10D-1 of the Securities Exchange Act of 1934, as amended (“Exchange Act”) and provides for the recovery 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 held outright or indirectly through the 401(k) plan.	☒   We do not permit the hedging 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

33

• 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’ 2023 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 2023, approximately 88% of our CEO’s annual target compensation, and on average, 79% 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, 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

34

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:

ADTRAN, Inc.	Infinera Corporation	Universal Display Corp.
Aspen Technology, Inc.	Inseego Corp.	Universal Electronics, Inc.
Aviat Networks, Inc.	Manhattan Associates, Inc.	Xperi, Inc.
Comtech Telecommunications, Corp.	Rambus, Inc.
Digi International, Inc.	Silicon Laboratories, Inc.
Dolby Laboratories, Inc.	Synaptics Inc.

Pearl Meyer 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. The data guides the Human Capital Committee in its efforts to set executive compensation levels and program targets at competitive levels for comparable roles in the marketplace. The Human Capital Committee uses the data to look for outliers or, in other words, to identify those executives whose target compensation is substantially below or above the 50^th percentile of the market data with the intention to target between the 50th and 75^th percentile. In addition, the Human Capital Committee takes into account other factors, such as the importance of each executive officer’s role to the company, individual expertise, experience and performance, retention concerns and relevant compensation trends in the marketplace, in making its final compensation determinations.

2023 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. Taking into account those factors, the salary levels of Messrs. Chen and Cohen received modest increases while Messrs. Brezski and Schmidt and Ms. Hakoranta received more substantial increases in order to ensure that their base salaries remained competitive and represented the importance of their roles to the company. All salary adjustments were effective March 1, 2023. No adjustment was made for Mr. Pankaj as the Human Capital Committee continued to believe that his base salary was appropriate. Set forth below are the 2022 and 2023 base salaries for our NEOs:

NEO	2022		2023		% Increase
Liren Chen	$	690,000	$	710,000		3	%
Richard J. Brezski	$	402,500	$	440,000		9	%
Eeva K. Hakoranta(1)	$	423,852	$	455,000		7	%
Rajesh Pankaj	$	490,000	$	490,000		—
Joshua D. Schmidt	$	350,000	$	400,000		14	%
Eric Cohen	$	408,408	$	425,000		4	%

⁽¹⁾  Ms. Hakoranta receives her salary and other cash compensation in euros. Amounts were converted to USD using an exchange rate for 2023 of 1.1056.

Short-Term Incentive Plan

The STIP annual incentive award is designed to provide a cash reward for 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 2023, the Human Capital Committee increased the CEO’s target bonus from 100% to 105% of base salary to better align with trends in the market. No other changes were made to the target STIP levels. Bonuses are capped at 200% of target for each executive.

NEO	2022 Target STIP Level (% of Base Salary)			2023 Target STIP Level (% of Base Salary)
Liren Chen		100	%		105	%
Richard J. Brezski		75	%		75	%
Eeva K. Hakoranta		75	%		75	%
Rajesh Pankaj		75	%		75	%
Joshua D. Schmidt		NA			60	%
Eric Cohen(1)		75	%		75	%

⁽¹⁾  Mr. Cohen was not eligible to receive 2023 STIP because he was no longer employed at the time of payout.

For 2023, in response to shareholder feedback, the Human Capital Committee changed the design of the STIP to ensure that corporate performance is a greater factor in determining payout. Beginning in 2023, baseline

36

funding of the STIP is determined entirely on corporate goal achievement with individual performance as a modifier. The STIP payout for 2023 was determined as follows:

Corporate Performance Goals. For 2023, 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:

2023 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* *excludes revenue recognized related to Samsung arbitration	Target is estimated recognized revenue as reported in 2023 financial statements Threshold = $360M Target = $460M	Minimum threshold set, below which would yield 0% achievement; threshold achievement yields 50% of target Each $1 million above threshold equals 0.5% achievement up to target; each $1 million achievement above target equals 1% achievement above target
Innovation (30%)	Patent filings	Patent filings – meet or exceed specified number of first patent filings Target = 640 first patent filings	Achievement based on % of target filings
Evolution (10%)	Execute Human Capital initiatives	Execute Human Capital initiatives with focus on Diversity, Equity and Inclusion	Bonus element pays out if specific, pre-defined strategic accomplishments were 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 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.

37

On February 1, 2024, the Chief Executive Officer reported to the Human Capital Committee on the final achievement of the strategic corporate goals and provided his assessment with respect to individual named executive officers’ performance for 2023. Actual achievement against each of these performance goals was determined at the conclusion of the fiscal year. 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	Maximum Payout*	Achievement	Component Payout
Total Revenue (1) (60%) *excludes revenue recognized related to Samsung arbitration	$360M 30%	$460M 60%		Total Revenue of $471M Each $1M above $460M is 1% achievement (achieved 111% of target)	67%
Innovation (30%)	0%	30%		Patent filings (achieved 191% of target)	57%
Evolution (10%)	0%	10%		Developed and launch Human Capital Initiatives (100% achievement)	10%
					134%
Overall Corporate Achievement	30%(2)	100%	Capped at 200%	134%

⁽¹⁾  Although no individual goal achievement is capped, the overall STIP payout is capped at 200%.

⁽²⁾  Assumes threshold revenue has been achieved.

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 2023, 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 continued to successfully execute on its strategy to increase revenue above the target, which was set above 2022 actual total revenue. In fact, 2023 revenue grew 20% over 2022, with recurring revenue increased to a record level of $408 million. Mr. Chen achieved continued revenue growth while maintaining cost discipline, resulting in an 82% increase in non-GAAP earnings per share.
Innovation	Mr. Chen’s continued emphasis on and support of innovation drove the record increase of first filings by 77% in 2023.
Evolution	Mr. Chen continued to support the evolution of the corporate culture, ensuring that new executives were successfully integrated into the executive team, continued to evolve the hybrid workplace and supported DE&I initiatives.

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 considered its own direct interactions with

38

each NEO as well. 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 2023 was as follows:

NEO	Personal Performance Factor (0%-200%)
Liren Chen		100	%
Richard J. Brezski		100	%
Eeva K. Hakoranta		100	%
Rajesh Pankaj		100	%
Joshua Schmidt		100	%

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 2023:

NEO	2023 Base Salary ($)		Target as percentage of base salary			Target bonus ($)		Corporate Achievement			Personal Performance			Overall achievement as % of target			Actual Bonus ($)
Liren Chen		710,000		105	%		745,500		134	%		100	%		134	%		998,970

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 generally 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.

2023 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 between the company’s NEOs

39

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 response to shareholder feedback, for 2023, the mix between time-based RSUs and performance-based RSUs for the company’s NEOs and other executives, other than the CEO, was adjusted to 50% performance-based RSUs and 50% time-based RSUs. The Human Capital Committee approved LTCP awards granted on March 31, 2023, comprised of the following equity vehicles:

NEO	2023 LTCP Grant: Equity Mix
	Performance-Based RSUs			Performance Based Stock Options			Time-Based RSUs
Liren Chen		33	%		34	%		33	%
Richard J. Brezski		50	%		0	%		50	%
Eeva K. Hakoranta		50	%		0	%		50	%
Rajesh Pankaj		50	%		0	%		50	%
Joshua D. Schmidt		50	%		0	%		50	%
Eric Cohen		50	%		0	%		50	%

The table below shows the target award values for the 2023 LTCP grant for each of the NEOs:

	Performance-Based RSUs ($) (1)		Performance-Based Stock Options ($) (2)		Time-Based RSUs ($) (1)		Total Value ($)
Liren Chen		1,500,000		1,500,000		1,500,000		4,500,000
Richard J. Brezski		750,000		—		750,000		1,500,000
Eeva K. Hakoranta		750,000		—		750,000		1,500,000
Rajesh Pankaj		750,000		—		750,000		1,500,000
Joshua D. Schmidt		500,000		—		500,000		1,000,000
Eric Cohen		550,000		—		550,000		1,100,000

⁽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.

2023 LTCP Time-based RSUs. Time-based RSUs granted to our NEOs in 2023 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.

2023 LTCP Performance-Based RSUs and Options. The actual number of performance-based RSUs and performance-based options (the “Performance Awards”) from the 2023 LTCP that may vest is based on the achievement of pre-determined goal(s) set by the Human Capital Committee. The metric for the 2023 LTCP goal is pro forma EBITDA, which measures overall profitability of the company.

The Performance Awards may vest at the end of the three-year performance period (January 1, 2023, through December 31, 2025) based on specified threshold, target, and maximum levels of pro forma EBITDA measured quarterly, on a trailing four quarter basis during years two and three of the performance period. The highest trailing four quarters determines goal achievement. If the threshold level of achievement is not met, there is no payout. Achievement of the threshold performance level will result in a 50% 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:

2019 LTCP Grant: The 2019 LTCP performance-based RSUs had a five-year performance period (January 1, 2019 through December 31, 2023). The performance goals associated with the 2019 LTCP performance-based RSUs required a threshold achievement of $150 million pro forma EBITDA, defined for this grant as EBITDA adjusted to eliminate stock based compensation, intellectual property enforcement costs and other non-recurring and non-operating items after adjustments to bring revenue in line with Revenue Platform. If the pro forma EBITDA threshold is met, Revenue Platform is measured to determine payout.

After reviewing the company’s achievement of the applicable goals as of December 31, 2023, the Human Capital Committee determined that the company’s goal achievement for the 2019 cycle was below the threshold required for the vesting of any portion of the performance-based RSU awards. As a result, all performance-based RSUs granted under the 2019 LTCP were forfeited. The goals associated with the 2019 LTCP were as follows:

	Threshold		Target		Maximum
Revenue Platform	$	400M	$	500M	$	600M
Pro forma EBITDA ($150 million threshold)

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:

	Threshold		Target		Superior
Pro forma EBITDA	$	150M	$	225M	$	300M

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

41

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.

Other 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 the lesser of (i) the amount of company stock with a value of at least five times his current annual base salary or (ii) 65,000 shares. The company’s other executive officers are expected to own the lesser of (i) the amount of company stock with a value of at least two times their current annual base salary or (ii) 12,500 shares.

In May 2023, in order to ensure that the guidelines were meaningful, the Human Capital Committee amended the stock ownership guidelines to modify the definition of qualifying stock to include only shares of common stock (held outright or shares held through the company’s 401(k) Plan (as defined below)) and restricted stock. Unvested time-based RSUs, unearned performance-based RSUs and unexercised options do not count towards ownership guidelines. 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 is calculated annually on the date of the company’s annual meeting of shareholders.

Any executive who has not reached or fails to maintain his or her target ownership level must retain at least 50% of any after-tax shares derived from vested RSUs or exercised options until his or her level is met. An executive may not make any disposition of shares that results in his or her holdings falling below the target level without the express approval of the Human Capital Committee. As of December 31, 2023, all of our executive officers were in compliance with the guidelines.

Clawback Policy

The company adopted a revised Clawback Policy, effective October 2, 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.

Prohibition Against Hedging

The company’s insider trading policy prohibits directors, officers, employees and consultants of the company from engaging in any hedging transactions involving company stock.

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.

42

As noted above, the IRS imposes limits on the amounts that an employee may contribute annually to a 401(k) Plan account. 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 2023, the company matched up to 50% of the first 6% of the participant’s eligible deferrals, determined on a combined plan basis taking into account deferred amounts under 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

In October 2018, the company adopted the InterDigital, Inc. Executive Severance and Change in Control Policy (the “Executive Severance Policy”), which had an initial term of three years and automatically renews for additional successive one-year periods thereafter (unless the company provides notice of non-renewal at least 30 days before the expiration of the term (as extended by any renewal period)). The policy applies to all NEOs except for Ms. Hakoranta, whose severance arrangements, in compliance with local law, are 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, each as defined in the Executive Severance Policy. Ms. Hakoranta’s employment agreement provides similar payments and benefits. For more information regarding the provisions governing these termination scenarios, please 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. Most recently, FW Cook reviewed our compensation programs. Based on 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.

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

43

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, for 2023, 2022, and 2021, became effective on March 1, 2023, March 1, 2022, and April 1, 2021. Amounts reported reflect the value of base salary earned by each NEO during such years.

(2) In connection with his hiring as CEO in April 2021, Mr. Chen received a sign-on cash bonus, the final third was paid in 2022 and in connection with his hiring as CTO in 2022, Mr. Pankaj received the final portions of his sign-on cash bonus in January and July 2023.

(3) Amounts reported reflect the aggregate 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, 2023. 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, 2023.

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:

NEO	Maximum Value Performance-Based RSU Awards 2023 LTCP ($)
Liren Chen		3,000,000
Richard J. Brezski		1,500,000
Eeva K. Hakoranta		1,500,000
Rajesh Pankaj		1,500,000
Joshua D. Schmidt		1,000,000
Eric Cohen		1,100,000

(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.

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%.

(6) Amounts reported include the value of payouts earned under the company’s 2023 STIP.

(1) Amounts reported represent the potential threshold, target and maximum STIP payouts depending on the level of performance achieved under the STIP for fiscal 2023. 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 2023, which is reported in the Summary Compensation Table above, was based on the company’s achievement of the 2023 strategic corporate goals established by the Human Capital Committee and individual performance of the NEO during 2023.

(2) Amounts reported represent the potential threshold, target and maximum number of PSUs the NEO could earn, measured as of the grant date, pursuant to his or her PSU award for the 2023 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 stock options the NEO could earn, measured as of the grant date. 100% achievement of the performance goal associated with the award results in a 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 2023 are scheduled to vest ratably over a three year period. Amounts reported for PSUs are 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 2023 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 4 to the Summary Compensation Table above for the grant date fair value of the PSUs 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.

(5) Grant date fair value of 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 2023 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 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 2023 assuming that the highest level of performance conditions will be achieved and the grants vest at their maximum level of 200% of target.

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.

(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.

(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.

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

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:

Name	Salary ($)		Non-Equity Incentive Plan Compensation ($)		All Other Compensation ($)
Liren Chen		477,692		916,880		3,004,237
Richard J. Brezski		342,482		19,500		104,388

Rajesh Pankaj		—		—		—
Joshua D. Schmidt		—		—		—
Eric Cohen		86,130		161,560		56,479

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,” our NEOs 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.

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 Chief Executive Officer two times the sum of 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 Chief Executive Officer, 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 Chief Executive Officer, 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 (in the case of our Chief Executive Officer, two and one half times ) plus one times the target bonus under the STIP then in effect 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 2017 Equity Plan.

The following table summarizes the benefits that become payable to an NEO 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:

(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. Ms. Hakoranta, pursuant to the terms of her employment agreement, is eligible for severance in the amount of 150% of base salary & pro-rata portion of STIP if she resigns for Good Reason, as defined in the 2017 Equity Plan.

(3) Pursuant to the terms of the Chen Offer Letter and as applicable to the Executive Severance Policy, new hire equity award agreements and 2021 LTCP equity agreements, 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 2017 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 after second anniversary of hire date, 200% of base salary and 18 months COBRA. For Ms. Hakoranta – if terminated for any reason other than summary dismissal, including resignation for Good Reason, eligible for severance in the amount of 150% of base salary & pro-rata portion of STIP. For other NEOs – per terms of Executive Severance Policy, 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 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 a 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.

56

(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 a 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.

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 – Eric Cohen

Pursuant to the term of the Executive Severance Policy, as a result of Mr. Cohen’s separation from InterDigital he was entitled to and did receive (i) severance in an amount equal to one and a half times his base salary then in effect; (ii) health coverage on terms and conditions comparable to those most recently provided for the period of one year; (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 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

57

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:

• 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:

2023: Richard Brezski; Eric Cohen, Eeva Hakoranta; Rajesh Pankaj; Joshua Schmidt

2022: Richard Brezski; Eric Cohen; Eeva Hakoranta; Rajesh Pankaj

2021: Richard Brezski; Eric Cohen; Eeva Hakoranta; Henry Tirri

2020: Richard Brezski; Richard Gulino; Kai Öistämö

(7) Adjusted EBITDA is a non-GAAP financial measure. See Appendix A for an explanation of this metric and a detailed reconciliation to the most directly comparable GAAP measure.

Most Important Performance Measures

In our assessment, the most important performance measures used to link CAP (as calculated in accordance with the SEC rules) to Company performance are listed below. The role of each of these performance measures in our executive compensation program is discussed in the CD&A.

• Adjusted EBIDTA

• Revenue

Descriptions of the Information Presented in the Pay Versus Performance Table

The illustrations below compare CAP (as calculated in accordance with the SEC rules) and the following measures:

• the Company’s cumulative TSR and the NASDAQ Telecommunications Index’s cumulative TSR;

• the Company’s Net Income;

• the Company’s Adjusted EBITDA; and

• the Company’s Revenue.

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:

• Annual Salary for fiscal year;

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

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

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.

EQUITY COMPENSATION PLAN INFORMATION

The following table summarizes the company’s equity compensation plan information relating to the common stock authorized for issuance under the company’s equity compensation plans as of December 31, 2023:

Plan Category	(a) Number of Securities to be Issued Upon Exercise of Outstanding Options, Warrants and Rights(1)		(b) Weighted-Average Exercise Price of Outstanding Options, Warrants and Rights		(c) Number of Securities Remaining Available for Future Issuance Under Equity Compensation Plans (excluding securities reflected in column (a))(2)
Equity compensation plans approved by InterDigital shareholders		1,834,457	$	66.79		1,430,842
Equity compensation plans not approved by InterDigital shareholders(3)		—		—		—
Total		1,834,457	$	66.79		1,430,842

(1) Column (a) includes 661,032 shares of common stock underlying outstanding time-based RSU awards, 451,801 shares of common stock underlying outstanding performance-based RSU awards, 698,901 shares of common stock underlying outstanding stock options, and 22,723 dividend equivalents credited in respect of unvested RSU awards. For Mr. Chen’s new hire performance-based RSUs and performance-based stock options, these amounts assume a maximum payout of 300% of target; all other performance-based RSUs and performance-based stock options assume a maximum payout of 200% of target. Because there is no exercise price associated with RSUs, these awards are not included in the weighted-average exercise price calculation presented in column (b). Dividend equivalents are paid in shares of common stock at the time, and only to the extent, that the related RSU awards vest.

(2) On June 17, 2017, the company’s shareholders adopted and approved the 2017 Equity Plan. On June 2, 2021, the company’s shareholders adopted and approved an amendment to the 2017 Equity Plan approving an additional 1,780,000 shares available under the plan. The 2017 Equity Plan provides for grants of stock options, stock appreciation rights, restricted stock, RSUs, performance units, performance shares and incentive cash bonuses. Amounts reported relate to securities available for future issuance under the 2017 Equity Plan, as amended.

(3) The company does not have any awards outstanding or shares remaining available for grant under equity compensation plans not approved by its shareholders.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

How many shares of the company’s common stock do the directors, director nominees, executive officers and certain significant shareholders own?

The following table sets forth information regarding the beneficial ownership of the 25,602,295 shares of our common stock outstanding as of March 31, 2024, except as otherwise indicated below, by each person who is known to us, based upon filings with the SEC, to beneficially own more than 5% of our common stock, as well as by each director, each director nominee, each NEO and all directors and executive officers as of the date of this proxy statement as a group. Except as otherwise indicated below and subject to the interests of spouses of the named beneficial owners, each named beneficial owner has sole voting and sole investment power with respect to the stock listed. None of the shares reported are currently pledged as security for any outstanding loan or indebtedness. If a shareholder holds options or other securities that are exercisable or otherwise convertible into our common stock within 60 days of March 31, 2024, pursuant to SEC rules, we treat the common stock underlying those securities as beneficially owned by that shareholder, and as outstanding shares when we calculate that shareholder’s percentage ownership of our common stock. However, pursuant to SEC rules, we do not consider that common stock to be outstanding when we calculate the percentage ownership of any other shareholder. The table below excludes dividends and dividend equivalent units that will be payable on April 24, 2024.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Related Person Transaction Procedures

The company has a written statement of policy with respect to related person transactions that is administered by the Audit Committee. Under the policy, a “Related Person Transaction” means any transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) between the company (including any of its subsidiaries) and a Related Person, in which the related person had, has or will have a direct or indirect interest. A “Related Person” includes any of our executive officers, directors or director nominees, any shareholder owning in excess of 5% of our common stock, any immediate family member of any of the foregoing persons, and any firm, corporation or other entity in which any of the foregoing persons is employed as an executive officer or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest. Related Person Transactions do not include certain transactions involving only director or executive officer compensation, transactions where the Related Person receives proportional benefits as a shareholder along with all other shareholders, transactions involving competitive bids, transactions involving certain bank-related services or certain other immaterial transactions.

Pursuant to the policy, a Related Person Transaction may be consummated or may continue only if:

• The Audit Committee approves or ratifies the transaction in accordance with the terms of the policy; or

• The chair of the Audit Committee, pursuant to authority delegated to the chair by the Audit Committee, pre-approves or ratifies the transaction and the amount involved in the transaction is less than $100,000, provided that, for the Related Person Transaction to continue, it must be approved by the Audit Committee at its next regularly scheduled meeting.

It is the company’s policy to enter into or ratify Related Person Transactions only when the Audit Committee determines that the Related Person Transaction in question is in, or is not inconsistent with, the best interests of the company, including but not limited to situations where the company may obtain products or services of a nature, quantity or quality, or on other terms, that are not readily available from alternative sources or where the company provides products or services to Related Persons on an arm’s length basis on terms comparable to those provided to unrelated third parties or on terms comparable to those provided to employees generally.

In determining whether to approve or ratify a Related Person Transaction, the committee takes into account, among other factors it deems appropriate, whether the Related Person Transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the Related Person’s interest in the transaction.

Transaction Involving Related Persons

Indemnification of Directors and Officers; Director Indemnity Agreements

We have Indemnification Agreements with certain of our directors and officers. Each Indemnification Agreement provides, among other things, that the company will, to the extent permitted by applicable law, indemnify each indemnitee if, by reason of such indemnitee’s status as a director or officer of the company, such indemnitee was, is or is threatened to be made a party to any proceeding, whether of a civil, criminal, arbitrational, administrative or investigative nature, against all expenses related thereto, including judgments, fines, penalties, excise taxes, interest and amounts paid in settlement and incurred by such indemnitee in connection with such proceeding, including attorneys’ fees). In addition, each of the Indemnification Agreements provides for the advancement of expenses incurred by the indemnitee in connection with any proceeding covered by the agreement, subject to certain exceptions. None of the Indemnification Agreements precludes any other rights to indemnification or advancement of expenses to which the indemnitee may be entitled, including but not limited to, any rights arising under our governing documents, any agreement, board action or applicable law.

69

DELINQUENT SECTION 16(A) REPORTS

Except as set forth below, based solely upon a review of filings with the SEC furnished to us and written representations that no other reports were required, we believe that, during and with respect to 2023, all of our directors and officers timely filed all reports required by Section 16(a).

On June 21, 2023, Mr. Kritzmacher filed a late Form 4 reporting one acquisition in October 2022 of 49 shares of our common stock. Mr. Kritzmacher was unaware of the transaction at the time it occurred, as it was executed by an investment advisor who had discretion to make individual investment decisions with respect to Mr. Kritzmacher’s managed account.

OTHER MATTERS

How may shareholders make proposals or director nominations for the 2025 annual meeting?

Shareholders interested in submitting a proposal for inclusion in our proxy statement for the 2024 annual meeting may do so by submitting the proposal in writing to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, DE 19809-3727. To be eligible for inclusion in our proxy statement for the 2024 annual meeting, shareholder proposals must be received no later than December 24, 2024, and they must comply with all applicable SEC requirements. The submission of a shareholder proposal does not guarantee that it will be included in our proxy statement.

Our bylaws also establish an advance notice procedure with regard to nominations of persons for election to the Board and shareholder proposals that are not submitted for inclusion in the proxy statement but that a shareholder instead wishes to present directly at an annual meeting. Shareholder proposals and nominations may not be brought before the 2025 annual meeting unless, among other things, the shareholder’s submission contains certain information concerning the proposal or the nominee, as the case may be, and other information specified in our bylaws, and we receive the shareholder’s submission no earlier than February 5, 2025, and no later than March 7, 2025. However, if the date of our 2025 annual meeting is more than 30 days before or more than 60 days after the anniversary of our 2024 annual meeting, the submission and the required information must be received by us no earlier than the 120th day prior to the 2025 annual meeting and no later than the later of the 90th day prior to the annual meeting or, if later, the 10th day following the day on which we first publicly announce the date of the 2025 annual meeting. Proposals or nominations that do not comply with the advance notice requirements in our bylaws will not be entertained at the 2025 annual meeting. A copy of the bylaws may be obtained on our website at http://ir.interdigital.com under the IR menu heading “ESG – Governance – Governance Documents,” or by writing to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, DE 19809-3727.

Who pays for the proxy solicitation costs?

We will bear the entire cost of proxy solicitation, including preparation, assembly, printing and mailing of the Notice, this proxy statement, the proxy card and any additional materials furnished to shareholders. Copies of proxy solicitation materials will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names that are beneficially owned by others to forward to such beneficial owners. In addition, we may reimburse such persons for their cost of forwarding the solicitation materials to such beneficial owners. Our directors, officers or regular employees may supplement solicitation of proxies by mail through the use of one or more of the following methods: telephone, email, telegram, facsimile or personal solicitation. No additional compensation will be paid for such services. For 2024, we have also engaged Alliance Advisors, LLC, a professional proxy solicitation firm, to aid in the solicitation of proxies from certain brokers, bank nominees and other institutional owners for an anticipated fee of not more than $12,000.

What is “householding” of proxy materials, and can it save the company money?

The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy delivery requirements for proxy materials with respect to two or more shareholders sharing the same address by delivering a single annual report and proxy statement to those shareholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for companies. Although we do not household for registered shareholders, a number of brokerage firms have instituted householding for shares held in street name, delivering a single set of proxy materials to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, now or in the future, you no longer wish to participate in householding and would prefer to receive a separate Notice or annual report and proxy

statement, please notify us by calling (302) 281-3600 or by sending a written request to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, DE 19809-3727, and we will promptly deliver a separate copy of our Notice or annual report and proxy statement, as applicable. If you hold your shares in street name and are receiving multiple copies of the Notice or annual report and proxy statement and wish to receive only one, please notify your broker.

How can I receive the annual report?

We will provide to any shareholder, without charge, a copy of our 2023 annual report on Form 10-K upon written request to our Corporate Secretary at InterDigital, Inc., 200 Bellevue Parkway, Suite 300, Wilmington, DE 19809-3727. Our 2023 annual report and this proxy statement are also available online at http://ir.interdigital.com/FinancialDocs.

Will there be any other business conducted at the annual meeting?

As of the date of this proxy statement, we know of no business that will be presented for consideration at the annual meeting other than the items referred to in this proxy statement. If any other matter is properly brought before the annual meeting for action by shareholders, proxies will be voted in accordance with the recommendation of the Board or, in the absence of such a recommendation, in accordance with the judgment of the proxy holder.

APPENDIX A

Adjusted EBITDA is a supplemental non-GAAP financial measure that InterDigital believes provide investors with important insight into the company’s ongoing business performance. InterDigital defines Adjusted EBITDA as net income attributable to InterDigital Inc. plus net loss attributable to non-controlling interest, income tax (provision) benefit, other income (expense) & interest expense, depreciation and amortization, share-based compensation, and other items. Other items include restructuring costs, impairment charges and other non-recurring items. This non-GAAP financial measure may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. A detailed reconciliation of Adjusted EBITDA to the most directly comparable GAAP financial measure is provided below.

Pro Forma EBITDA is a supplemental non-GAAP financial measure that InterDigital uses for compensation purposes as described in this proxy statement. InterDigital defines Pro Forma EBITDA as total revenues minus operating expenses plus depreciation and amortization, intellectual property enforcement costs, and other items. Other items include restructuring costs, impairment charges and other non-recurring items, as further described below. This non-GAAP financial measure may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

(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:
