Who May Attend

You may virtually attend the Annual Meeting if you owned your shares, either as a stockholder of record or as a beneficial owner (as described below), as of the close of business on February 26, 2025 (the “Record Date”).

Stockholders of Record. If your shares are registered directly in your name, then you are considered to be the stockholder of record with respect to those shares, and we are providing these proxy materials directly to you. Instructions on how to attend virtually and participate via the Internet, including how to demonstrate proof of stock ownership, are posted at http://www.virtualshareholdermeeting.com/RMBS2025. Stockholders may vote while virtually attending the meeting on the Internet.

Beneficial Owners. If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in “street name,” and your broker, bank or nominee will forward these proxy materials to you. Your broker, bank or nominee is considered to be the stockholder of record with respect to those shares. “Street name” stockholders who wish to vote virtually during the Annual Meeting will need to obtain a “legal proxy” from the broker, bank or nominee that holds their shares and that broker, bank or nominee will likely require voting instructions to be submitted. Please consult your broker, bank or nominee for additional information on how to vote your shares.

Who May Vote

Voting Your Proxy

Stockholders of Record. If you hold your shares in your own name as a holder of record, you may instruct the proxy holders how to vote your common stock by:

•  voting via the internet at http://www.proxyvote.com/;

•  voting by telephone at 1-800-690-6903; or

•  voting by mail by signing, dating and mailing the proxy card in the postage-paid envelope provided.

Even if you vote your shares by proxy, you may also choose to attend the Annual Meeting virtually and vote your shares during the Annual Meeting. If you provide instructions in your completed proxy card, the proxy holders will vote your shares in accordance with those instructions. If you sign and return a proxy card without giving specific voting instructions, your shares will be voted “FOR” all of the proposals described herein.

We are not aware of any matters to be presented during the Annual Meeting other than those described in this Proxy Statement. If any matters not described in this Proxy Statement are properly presented during the meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the meeting is adjourned or postponed, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy prior to the new meeting date.

Subject to any rules your broker, bank or other nominee may have, you can change your vote or revoke your proxy before the Annual Meeting.

If you are a registered stockholder, you may change your vote by:

•  entering a new vote via the Internet or by telephone by 11:59 p.m. Eastern Time on April 23, 2025; or

•  virtually attending the Annual Meeting and voting.

If you are a registered stockholder, you may also revoke your proxy by providing our Corporate Secretary with a written notice of revocation prior to your shares being voted at the Annual Meeting. Such written notice of revocation should be hand delivered to our Corporate Secretary or mailed to and received by Rambus prior to the Annual Meeting at 4453 North First Street, Suite 100, San Jose, California 95134, Attention: Corporate Secretary.

If you are a street name stockholder, you may change your vote by:

•  submitting new voting instructions to your broker, bank or other nominee pursuant to instructions provided by such broker, bank or other nominee; or

•  virtually attending the Annual Meeting and voting (to do so, you must have obtained a “legal proxy” from your broker, bank or other nominee giving you the right to vote your shares).

If you are a street name stockholder, you must contact your broker, bank or other nominee that holds your shares to find out how to revoke your proxy.

When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted during the Annual Meeting in accordance with the directions of the stockholder. However, if no specific instructions are given, the shares will be voted in accordance with the following recommendations of our Board of Directors:

•  “FOR” the election of Emiko Higashi, Steven Laub, and Eric Stang as Class II directors;

•  “FOR” the ratification of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025; and

•  “FOR” the advisory vote to approve named executive officer compensation;

We treat shares that are voted “ABSTAIN” during the meeting or by proxy as being present for purposes of determining whether or not a quorum is present during the Annual Meeting.

In the election of directors, any abstentions in respect of a nominee will not impact the election of that nominee. In tabulating the voting results for the election of directors, only “FOR” and “AGAINST” votes are counted.

For Proposals Two and Three, an “ABSTAIN” vote is the same as voting against the Proposal.

If you hold your common stock through a broker, bank or nominee, the broker, bank or nominee may be prevented from voting these shares on non-routine matters (a “broker non-vote”) unless you have given the broker, bank or nominee voting instructions. Thus, if you hold your common stock through a broker, bank or nominee, it is critical that you provide your broker, bank or nominee with instructions on how to vote your shares if you want your vote to count. If you hold your common stock through a broker, bank or nominee and you do not instruct your broker, bank or nominee how to vote on Proposals One or Three, we expect it will be considered a broker non-vote and, accordingly, no votes will be cast on your behalf with respect to such Proposal. Shares that are subject to a broker non-vote are counted for purposes of determining whether a quorum exists, but do not count for or against any particular proposal.

Proposal Two, Ratification of Appointment of Independent Registered Public Accounting Firm, is the only routine matter for which banks, brokers or nominees will have discretionary voting power.

Stockholders may present proper proposals for inclusion in our proxy statement and for consideration at the next annual meeting of stockholders by submitting their proposals in writing to our Corporate Secretary in a timely manner. Stockholder proposals must comply with the requirements of Rule 14a-8 under the Securities Exchange Act regarding the inclusion of stockholder proposals in company-sponsored proxy materials.

To be timely for our annual meeting of stockholders in 2026, a stockholder proposal made pursuant to Rule 14a-8 must be received by the Company’s Secretary at the principal executive offices of the Company not later than November 7, 2025.

Our bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our proxy statement.

Our bylaws provide that the only business that may be conducted at an annual meeting is business that is brought (A) pursuant to our proxy materials with respect to such meeting, (B) by or at the direction of the Board of Directors, or (C) by a stockholder of the Company who (1) is a stockholder of record both at the time of giving notice of such business and on the record date for the determination of stockholders entitled to vote during the annual meeting and (2) has timely complied in proper written form with the notice procedures set forth in our bylaws.

To be timely for our annual meeting of stockholders in 2026, a stockholder proposal not made pursuant to Rule 14a-8 must be received by the Company’s Secretary at the principal executive offices of the Company:

•  not earlier than December 22, 2025; and

•  not later than January 21, 2026.

In the event that the date of the 2026 annual meeting of stockholders is changed by more than 25 days from the one-year anniversary of the date of this year’s annual meeting, then notice of a stockholder proposal not intended to be included in our proxy statement must be received no earlier than the close of business on the 120th day before such annual meeting and no later than the close of business on the later of the following two dates:

•  the 90th day prior to such annual meeting; or

•  the 10th day following the day on which public announcement of the date of such annual meeting is first made.

Any notice of proposed business must contain specific information concerning the matters to be brought before the meeting in accordance with our bylaws. We urge you to read our bylaws in full in order to

understand the requirements of bringing a proposal or nomination. If a notice containing all the required information is not timely delivered, your proposal will not be presented.

All notices of proposals by stockholders, whether or not they are intended to be included in our proxy materials, should be sent to Rambus Inc., 4453 North First Street, Suite 100, San Jose, California 95134, Attention: Corporate Secretary/General Counsel.

Our Board of Directors may be contacted by writing to them via mail at Board of Directors, Rambus Inc., 4453 North First Street, Suite 100, San Jose, California 95134. If you wish to contact our Board of Directors or any member of the Audit Committee to report questionable accounting or auditing matters, you may do so anonymously by using this mailing address and designating the communication as “confidential.”

Our process for handling communications to our Board of Directors is as follows:

Any stockholder communications that our Board of Directors receives will first go to our Corporate Secretary/General Counsel, who will log the date of receipt of the communication as well as (for non-confidential communications) the identity of the correspondent in our stockholder communications log. Unless the communication is marked “confidential,” our Corporate Secretary/General Counsel will review, summarize and, if appropriate, draft a response to the communication. The summary and response will become part of the stockholder communications log that our Corporate Secretary/General Counsel maintains with respect to all stockholder communications. Our Corporate Secretary/General Counsel will then forward the stockholder communication to the member(s) of our Board of Directors (or committee chair, if the communication is addressed to a committee) for review. Any stockholder communication marked “confidential” will be logged by our Corporate Secretary/General Counsel as “received” but will not be reviewed, opened or otherwise held by our Corporate Secretary/General Counsel. Such confidential correspondence will be forwarded to the addressee(s).

The Securities and Exchange Commission (the “SEC”) has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements with respect to two or more

Three Class II directors are to be elected during the Annual Meeting for a two-year term ending in 2027. Based on the recommendation of our Corporate Governance/Nominating Committee, our Board of Directors has nominated Emiko Higashi, Steven Laub, and Eric Stang for election as Class II directors.

If any of these persons nominated by the Board of Directors is unable or declines to serve as a director at the time of the Annual Meeting, proxies will be voted for a substitute nominee or nominees designated by the Board of Directors.

The Company’s bylaws provide that in uncontested elections, a nominee for director shall be elected to the Board of Directors if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election. The Board of Directors, after taking into consideration the recommendation of the Corporate Governance/Nominating Committee of the Board of Directors, will determine whether or not to accept the pre-tendered resignation of any nominee for director, in an uncontested election, who receives a greater number of votes “AGAINST” his or her election than votes “FOR” such election. There are no cumulative voting rights in the election of directors. Stockholders as of the Record Date may vote their shares for or against some, all or none of the Class II nominees.

In the election of directors, any abstentions or broker non-votes in respect of a nominee will not impact the election of that nominee. In tabulating the voting results for the election of directors, only “FOR” and “AGAINST” votes are counted.

The Board unanimously recommends that you vote “FOR” the election to the Board of Directors each of our Class II nominees: Emiko Higashi, Steven Laub, and Eric Stang.

The members of our Board of Directors have deep executive and board leadership experience derived from their respective tenures as executives and directors of technology companies of various sizes. The following table contains information regarding the Class II nominees and other directors as of March 7, 2025. This information includes the specific experience, qualifications, attributes, and skills that led to our Board of Directors’ conclusion that the person should be nominated to serve as a director.

Except as may be required by rules promulgated by Nasdaq or the SEC, there are currently no specific, minimum qualifications that must be met by each candidate for our Board of Directors, nor are there any specific qualities or skills that are necessary for one or more of the members of our Board of Directors to possess. The Corporate Governance/Nominating Committee considers a number of factors in its assessment of the appropriate skills and characteristics of members of the Board of Directors, as well as the composition of the Board of Directors as a whole. These factors include the members’ qualification as independent, as well as consideration of judgment, character, integrity, diversity, skills, and experience in such areas as operations, technology, finance, the semiconductor industry, and the general needs of the Board of Directors and such other factors as the Corporate Governance/Nominating Committee may consider appropriate. The Corporate Governance/Nominating Committee does not have a formal policy with respect to diversity. However, the Board of Directors and the Corporate Governance/Nominating Committee believe that it is essential that the members of the Board of Directors represent diverse viewpoints. In considering candidates for the Board of Directors, the Board of Directors and the Corporate Governance/Nominating Committee consider the entirety of each candidate’s credentials in the context of the factors mentioned above.

We are committed to maintaining the highest standards of business conduct and corporate governance, which we believe are essential to running our business efficiently, serving our stockholders’ interests and maintaining our integrity in the marketplace. We have adopted a code of business conduct and ethics that applies to all of our directors, officers and employees, known as the Code of Business Conduct and Ethics. The Code of Business Conduct and Ethics is available on our website at https://investor.rambus.com/corporate-governance/governance-documents/ default.aspx. We will post amendments to our Code of Business Conduct and Ethics on the same website.

It is the policy of the Board of Directors to have executive sessions of the independent directors at which only independent directors are present, typically in conjunction with the regularly scheduled meetings of the Board of Directors.

During 2024, our Board of Directors had five standing committees:

•  an Audit Committee,

•  a Compensation and Human Resources Committee,

•  a Corporate Governance/Nominating Committee,

•  a Corporate Development Committee, and

•  a Cyber Risk Committee.

The following describes each standing committee, its function, its membership, and the number of meetings held during 2024.

Each of the standing committees operates pursuant to a written charter adopted by our Board of Directors. All of the current committee charters are available on our website at https://investor.rambus.com/corporate-governance/governance-documents/default.aspx.

Currently, the Audit Committee is composed of Meera Rao (Chair), Charles Kissner and Emiko Higashi. The Audit Committee oversees our corporate accounting and financial reporting processes and internal control over financial reporting, as well as our internal and external audits. The Audit Committee held 12 meetings during 2024. Its duties include:

•  Reviewing our accounting and financial reporting processes and internal controls over financial reporting;

•  Providing oversight and review at least annually of our risk management policies, including our investment policy;

•  Retaining the independent registered public accounting firm, approving their fees, and providing oversight of communication with them;

•  Reviewing the plans, findings and performance of our internal auditors;

•  Reviewing our annual and quarterly financial statements and related disclosure documents; and

•  Overseeing special investigations into financial and other matters, as necessary.

Our Board of Directors has determined that each member of the Audit Committee is an “audit committee financial expert,” that each member is “financially sophisticated” and is able to read and understand fundamental financial statements, each as required by Nasdaq. No member of the Audit Committee has a material relationship with us (either directly or as a partner, stockholder or officer of an organization that has a relationship with us) and

each member of the Audit Committee satisfies the independence requirements for Audit Committee membership under the applicable Nasdaq and SEC rules.

The Audit Committee’s role is detailed in the Audit Committee Charter, which is available on our website at https://investor.rambus.com/corporate-governance/governance-documents/default.aspx.

Currently, the Compensation and Human Resources Committee is composed of Eric Stang (Chair), Steven Laub, and Necip Sayiner.

Our Board of Directors has determined that each of Messrs. Stang, Laub, and Sayiner are independent for Compensation and Human Resources Committee independence under the applicable Nasdaq and SEC rules. The Compensation and Human Resources Committee reviews and determines all forms of compensation, including base compensation, bonuses, and stock compensation, to be provided to our executive officers (including the named executive officers) and directors of Rambus. The Compensation and Human Resources Committee held 13 meetings during 2024. Its duties include:

•  Annually reviewing and approving the Chief Executive Officer (“CEO”) and other executive officers’ compensation in the context of their performance, which includes reviewing and approving their annual base salary, annual incentive bonus (including the specific goals, targets, and amounts), equity compensation, any employment agreements, and any other benefits, compensation or arrangements, as applicable;

•  Administering our equity incentive plans pursuant to the terms of such plans and the authority delegated by our Board of Directors, including: granting awards of stock options, performance shares, performance units, stock appreciation rights, restricted stock, restricted stock units (“RSUs”) or other equity compensation to individuals eligible for such grants and amending such awards following their grant; amending the plans; and delegating to appropriate executive officers of the Company the ability to grant awards to non-executive officer employees of the Company pursuant to specific guidelines;

•  Adopting, amending and overseeing the administration of our significant employee benefits programs;

•  Reviewing external surveys to establish appropriate ranges of compensation;

•  Retaining and terminating any compensation consultant to assist in the evaluation of CEO or executive officer or director compensation, and approving the consultant’s fees and other terms of service, as well as obtaining advice and assistance from internal or external legal, accounting or other advisors;

•  Overseeing the Company’s processes for identifying and managing risks arising from its compensation policies and practices and from other human resources matters, reviewing and discussing with management the risks that are reasonably likely

to have a material adverse effect on the Company, and reporting to the Board regarding these matters; and

•  Conducting an annual assessment of the Company’s engagement with compensation consultants retained by the Board and/or management, as applicable, including the nature and extent of services provided, the amount of fees paid and who made or recommended the decision to retain the compensation consultants.

The Compensation and Human Resources Committee retained Farient Advisors LLC (“Farient”) in 2024 to assist in evaluating executive and director compensation and has determined that Farient is an independent consultant under applicable Nasdaq and SEC rules.

A detailed description of the processes and procedures of the Compensation and Human Resources Committee for considering and determining executive and director compensation, including the role of Farient, is provided in the “Executive Compensation” section of this proxy statement.

The Compensation and Human Resources Committee’s role is detailed in the Compensation and Human Resources Committee Charter, which is available on our website at https://investor.rambus.com/corporate-governance/governance-documents/default.aspx.

None of the members of our Compensation and Human Resources Committee is or has ever been an officer or employee of Rambus. None of our executive officers currently serves, or in the past year has served, as a member of the board or compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board) of any entity that has one or more executive officers serving on our Board of Directors or Compensation and Human Resources Committee. Please see the Compensation Discussion and Analysis section of this Proxy Statement for further discussion.

Currently, the Corporate Governance/Nominating Committee is composed of Emiko Higashi (Chair), Charles Kissner and Eric Stang. Our Board of Directors has determined that each of Ms. Higashi and Messrs. Kissner and Stang are “independent” under applicable Nasdaq and SEC rules. The Corporate Governance/Nominating Committee held five meetings during 2024.

The Corporate Governance/Nominating Committee recommends and approves Rambus’ Corporate Governance Guidelines. Its duties include:

•  Evaluating and making recommendations to the Board of Directors concerning the appointment of directors to committees of the Board of Directors and the selection of committee chairs;

•  Identifying best practices and recommending corporate governance principles;

•  Overseeing the evaluation of the Board of Directors; and

•  Proposing the slate of nominees for election to the Board of Directors.

The Corporate Governance/Nominating Committee’s role is detailed in the Corporate Governance/Nominating Committee Charter which is available on our website at https://investor.rambus.com/corporate-governance/governance-documents/default.aspx.

Currently, the Corporate Development Committee is composed of Necip Sayiner (Chair), Emiko Higashi, and Steven Laub. The Corporate Development Committee held six meetings during 2024. The duties of the Corporate Development Committee include:

•  Reviewing and advising management with respect to our growth strategy;

The Corporate Governance/Nominating Committee utilizes a variety of methods for identifying and evaluating nominees for director, including those discussed in the “Director Qualifications” section of this proxy statement. In the event that vacancies on the Board of Directors are anticipated, or otherwise arise, the committee will consider various potential candidates for director. Candidates may come to the attention of the committee through current members of the Board of Directors, professional search firms, stockholders or other persons. The Corporate Governance/Nominating Committee has from time to time retained third parties to whom a fee is paid to assist it in identifying or evaluating potential director nominees.

Stockholders may propose director candidates for general consideration by the Corporate Governance/Nominating Committee by submitting to the Corporate Secretary/General Counsel of the Company, in proper written form, the individual’s name, qualifications, and the other information required by our bylaws for stockholder nominations submitted as set forth above in “Procedure for Submitting Stockholder Proposals/Nominations.” The Corporate Governance/Nominating Committee will evaluate any candidates recommended by stockholders against the same criteria and pursuant to the same policies and procedures applicable to the evaluation of candidates proposed by directors or management.

Majority Voting Policy

In addition, the Audit Committee is responsible for oversight of the Company’s processes to manage financial risk and oversees and reviews at least annually our risk management policies, including our business interruption and other risk policies and our investment policies.

The Compensation and Human Resources Committee oversees the Company’s processes for identifying and managing risks arising from its compensation policies and practices and from other human resources matters.

None.

All of our directors and executive officers are subject to our Code of Business Conduct and Ethics, and our directors are guided in their duties by our Corporate Governance Guidelines. Our Code of Business Conduct and Ethics requires that our directors and executive officers avoid situations where a conflict of interest might occur or appear to occur. In general, our directors and executive officers should not have a pecuniary interest in transactions involving us or a customer, licensee, or supplier of the Company, unless such interest is solely a result of routine investments made by the individual in publicly traded companies.

In the event that a director or executive officer is going to enter into a related party transaction with a relative or significant other, or with a business in which a relative or significant other is associated in any significant role, the director or executive officer must fully disclose the nature of the related party transaction to our Chief Financial Officer. For directors and executive officers, such related party transaction then must be reviewed and approved in advance by the Audit Committee. For other conflicts of interest that may arise, the Code of Business Conduct and Ethics advises our directors and executive officers to consult with our General Counsel.

In addition, each director and executive officer is required to complete a Director and/or Officer Questionnaire on an annual basis and upon any new appointment, and provide quarterly updates, which requires disclosure of any related-party transactions pertaining to the director or executive officer. Our Board of Directors will consider such information in its determinations of independence with respect to our directors under applicable Nasdaq and SEC rules. In order to help ensure our directors remain free from conflicts or the appearance of conflicts, our Corporate Governance Guidelines require that each director deliver an irrevocable resignation from the Board of Directors, to be effective upon the occurrence of both (i) a significant change in his or her status and appointments or positions with other companies during his or her tenure as a director on the Board of Directors, and (ii) the Board of Directors’ acceptance of such resignation.

The Company’s bylaws:

•  provide that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery in the

State of Delaware, the Company’s state of incorporation, shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, stockholder, employee or agent of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against the Company or any current or former director, officer, stockholder, employee or agent of the Company arising out of or relating to any provision of the Delaware General Corporation Law or the Company’s certificate of incorporation or bylaws or (iv) any action asserting a claim against the Company or any current or former director, officer, stockholder, employee or agent of the Company governed by the internal affairs doctrine of the State of Delaware (or if the Court of Chancery in the State of Delaware lacks subject matter jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall be another state or federal court located within the State of Delaware) (“Delaware Forum Provision”); and

•  provide that, unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933 (the “Securities Act”), as amended, against any person in connection with any offering of the Company’s securities (“Federal Forum Provision”).

The Company believes that the Delaware Forum Provision and the Federal Forum Provision are in the best interests of the Company. The Company believes the Delaware Forum Provision may provide potential cost savings by eliminating duplicative litigation in more than one forum and will eliminate risks of unpredictable or incorrect outcomes from courts that are unfamiliar with Delaware law, or even unfamiliar with corporate law generally. Further, the Company believes that the Federal Forum Provision will reduce the risk that the Company could be involved in duplicative litigation in both state and federal courts, as well as the risk that the outcome of cases in multiple forums could be inconsistent.

The Federal Forum Provision does not specify any particular U.S. federal district court as the exclusive forum for claims under the Securities Act, so a plaintiff could select, on the basis of convenience or for other reasons, the U.S. federal district courts in any state as the forum for any such claim.

The Delaware Forum Provision and the Federal Forum Provision give the Company the flexibility to consent to an alternative forum when the Company deems it appropriate. In addition, the Company did not adopt the Delaware Forum Provision or the Federal Forum Provision in anticipation of any specific litigation confronting the Company; rather, the Delaware Forum Provision and the Federal Forum Provision were adopted on a prospective basis to help mitigate potential future harm to the Company and its shareholders.

Performance-based equity compensation awards that vest based upon our total stockholder return (“TSR”) relative to the TSR of certain semiconductor index companies over a three-year period to closely align our NEO’s interests with those of our stockholders.

Emphasis on performance-based compensation in our pay mix. Approximately 91% of our CEO’s total target compensation, and on average, approximately 83% of our other NEOs’ total target compensation was subject to our financial and/or share price performance in 2024.

Alignment between executive compensation and stockholder interests, achieved by emphasizing long-term compensation in our pay mix. In 2024, approximately 60% of our CEO’s target long-term equity incentive awards and 50% of other NEOs’ target long-term equity incentive awards consisted of PSUs as described below.

Close alignment of our annual incentive compensation program (“Corporate Incentive Plan” or “CIP”) with Company performance. Our 2024 CIP program was funded based on the achievement of an objective performance target of pro-forma operating income. Pro-forma operating income performance for 2024 was targeted at $276.2 million and the Company actually achieved pro-forma operating income of $263.3 million. The 2024 CIP pool was funded at 94.8%.

✓  There is a strong link between pay and performance

✓  Our Board is led by an independent Non-Executive Chairperson

✓  A significant portion of our NEOs’ target compensation is subject to Company financial and/or share price performance

✓  Pursuant to our Code of Business Conduct and Ethics, all employees and directors are prohibited from engaging in hedging transactions in Rambus shares, including short sales and purchases of put and call options, and our Insider Trading Policy prohibits certain insiders from pledging Rambus shares as collateral for loans

✓  We retain an independent compensation consultant

✓  We have adopted a compensation clawback policy that applies to our executive officers and we also retain the right to reduce or withhold future compensation based on any restatement or adjustment to our financials, and to determine the extent to which recovery of prior compensation may be pursued, in each case in the event of fraud

✓  We adhere to robust risk management policies, including investment, legal, operational, financial, and strategic risks

✓  We do not provide tax gross-ups and vesting of outstanding equity awards may only accelerate upon a “double-trigger” following a change in control when applicable

✓  Our executive compensation program is annually submitted to our stockholders for an advisory vote

✓  Our 2015 Plan, most recently amended in April 2023, prohibits the repricing of underwater stock options

Amounts shown are the aggregate grant date fair value computed in accordance with the provisions of FASB ASC Topic 718. The estimated fair value of PSUs was calculated based on the probable outcome of the performance measures for the fiscal year 2024 performance period as of the grant date. These amounts do not necessarily correspond to the actual value recognized by NEOs. The assumptions used to calculate the value of stock awards are set forth under Note 14 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024. The performance period for PSUs granted in fiscal year 2022 ended on December 31, 2024. Upon the achievement of the performance criteria associated with such awards, 191,548 of Mr. Seraphin’s PSUs vested, 39,072 of Mr. Lynch’s PSUs vested, 112,675 of Mr. Fan’s PSUs vested and 18,777 of Mr. Shinn’s PSUs vested.

Amounts for fiscal year 2024 consist of compensation earned for services rendered in fiscal year 2024 and are based upon the achievement of certain targets under the Company’s 2024 Corporate Incentive Plan. The target and achievement results were reviewed and approved by the Compensation and Human Resources Committee. The plan is further described under “Compensation Discussion & Analysis — Components of Executive Compensation.”

“All Other Compensation” for NEOs for 2024 includes a 401K match, life insurance premium payments, employer-paid health savings account contributions, and a bring your own device to work stipend.

Each NEO agreed to a temporary pay reduction of 10% during the period of January 31, 2023, to March 31, 2023, as part of general corporate cost cutting measures at the time. Each NEO’s base salary was restored to the level indicated in the table above as of April 1, 2023, and the NEOs did not receive any additional compensation as a result of the temporary pay reduction.

Mr. Lynch was provided a retention bonus of $100,000.

Amounts in the “Estimated Future Payouts Under Equity Incentive Plan Awards” columns relate to payout opportunities for fiscal year 2024 PSUs, which were granted under our 2015 Plan. The PSUs vest solely based upon our relative TSR to the median TSR of the SOX semiconductor index companies, excluding the Equipment Companies, during a three-year performance period. The amounts shown in the Threshold column reflect the PSUs that become eligible to vest if our TSR percentage point spread below the median TSR of the SOX semiconductor index companies, excluding the Equipment Companies, is -15%, and pay out at 25% of Target. The amounts shown in the Target column reflect the PSUs that become eligible to vest if our TSR percentage point spread relative to the median TSR of the SOX semiconductor index companies, excluding the Equipment Companies, is 0%, and pay out at 100% of Target. The amounts shown in the Maximum column reflect the PSUs that become eligible to vest if our TSR percentage point spread above the median TSR of the SOX semiconductor index companies, excluding the Equipment Companies, is equal or greater than 25%, and pay out at 200% of Target. The number of PSUs that become eligible to vest will be interpolated on a linear basis between the threshold and maximum levels. The vesting of the PSUs is subject to the NEO’s continued service to the Company through the vesting date set forth in the award agreement, or earlier, upon a change in control or a qualifying termination, and the payout percentage will be capped at 100% if the Company’s TSR is negative. The PSUs are discussed more fully in “Compensation Discussion and Analysis-Components of Executive Compensation” above.

Granted on April 1, 2024, and vest in four equal annual installments beginning on April 1, 2025. The vesting of the RSUs is subject to the NEO’s continued service to the Company through the applicable vesting dates on each anniversary from the date of grant through the fourth anniversary.

The amounts reported in this column reflect the aggregate grant date fair value of the RSUs and PSUs granted to our NEOs in fiscal year 2024 as computed in accordance with ASC Topic 718.

The value realized equals the market value of our common stock on the vesting date multiplied by the number of shares that vested.

the median of the annual total compensation of all employees of our company (other than our CEO), was $191,416; and

the annual total compensation of our CEO, as reported in the Summary Compensation Table presented elsewhere in this proxy statement, was $7,168,732.

We selected December 31, 2024, which is the last day of our fiscal year, as the date upon which we would identify the median employee.

During fiscal year 2024, our employee population consisted of approximately 712 individuals, including employees in the United States, Australia, Canada, China, Finland, France, Germany, India, Japan, the Netherlands, Bulgaria, South Korea, Taiwan and the United Kingdom. Of these employees, 342 were located in the United States and 370 were located outside of the United States.

When determining our median employee, we excluded all employees from Australia (1), Germany (1), Japan (3) and United Kingdom (3), which is less than 5% of our total employee population (based on an employee count of 712 under the de minimis exception provided for in Item 402(u)).

To identify the “median employee” from our employee population we used payroll and equity plan records for January 1, 2024 through December 31, 2024 (the “compensation measure”).

The compensation measure included the following: base salary, employer cost of benefits, employer retirement plan contributions, including 401(k) matching, bonus payments, grant date fair value of equity awards, employee stock purchase plan discounts and sales commissions.

For countries other than the United States, India, China and South Korea, the employer cost of benefits was calculated based on the average employer cost per country and, for countries in the European Union, includes the cost of holidays.

Amounts paid in foreign currency were converted into United States dollars using exchange rates in effect as of December 31, 2024.

With respect to the annual total compensation of the “median employee,” we identified and calculated the elements of such employee’s compensation for fiscal year 2024 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $191,416.

With respect to the annual total compensation for the CEO, we used the amount reported in the “Total” column of our 2024 Summary Compensation Table for Mr. Seraphin.
