PROXY STATEMENT

INFORMATION CONCERNING SOLICITATION AND VOTING

This proxy statement and the accompanying proxy card are furnished in connection with the solicitation of proxies by the Board of Directors (the “Board of Directors” or the “Board”) of Amkor Technology, Inc. (“Amkor,” “we,” “us,” or the “Company”). Our principal executive office is located at 2045 East Innovation Circle, Tempe, Arizona 85284, telephone number (480) 821-5000. The proxies will be voted at the Annual Meeting of Stockholders to be held on Tuesday, May 14, 2024 at 9:00 a.m. EDT and any adjournment or postponement thereof (the “Annual Meeting”).

The Annual Meeting will be held virtually, via the internet, at meetnow.global/MRHAM2U. At our virtual Annual Meeting, stockholders will be able to attend, vote, and submit questions via the internet.

We intend to mail definitive copies of these proxy materials on or about April 12, 2024 to stockholders of record who held our common stock at the close of business on March 22, 2024 (the “Record Date”).

The following is important information regarding the Annual Meeting and this proxy statement.

In advance of the Annual Meeting, we encourage you to carefully review our admission procedures at meetnow.global/MRHAM2U. We also recommend that you log in at least 15 minutes before the start to ensure you are logged in when the Annual Meeting starts. If you encounter any technical difficulties accessing the Annual Meeting during check-in or at any other time during the Annual Meeting, please call the technical support phone number that will be posted on the virtual Annual Meeting login page.

1

If your shares are held by a bank, brokerage firm, or other record holder, please refer to your proxy card or other information provided to you for instructions on how to vote.

If you hold your shares through a broker and do not provide your broker with specific voting instructions, under the rules that govern brokers in such circumstances, your broker will have the discretion to vote such shares on routine matters but not on non-routine matters. Even though we are a company listed on the Nasdaq Global Select Market (“Nasdaq”), the New York Stock Exchange (“NYSE”) rules govern how a broker licensed by the NYSE can vote shares it holds on behalf of stockholders of Nasdaq-listed companies. As a result, your broker:

Because the proposals to be acted upon at the Annual Meeting include both routine and non-routine matters, we anticipate that brokers may return proxy cards that vote uninstructed shares “FOR” or “AGAINST” Proposal Three, but expressly state that the broker is NOT voting on Proposal One, Proposal Two, or Proposal Four. A broker’s withholding of a vote, in this case with respect to Proposal One, Proposal Two, or Proposal Four, is referred to as a “broker non-vote.” Broker non-votes will not be counted as present or represented for purposes of determining whether stockholder approval of a matter has been obtained and thus will not have an effect on the outcome of the vote.

If you abstain from voting on Proposal Two, Proposal Three, or Proposal Four, the abstention will have the same effect as a vote against the proposal. If you abstain from voting on Proposal One, the abstention will not have an effect on the outcome of the vote.

2

If you intend to submit a proposal or nomination for director for the 2025 Annual Meeting (but not seek inclusion of such proposal or nomination in the Company’s proxy materials), you must comply with the advance notice provisions in our bylaws (the “Bylaws”). To be timely, we must receive written notice of your proposal no earlier than January 14, 2025 and no later than February 13, 2025.

All proposals must, under law, be an appropriate subject for stockholder action and must be submitted in writing to Amkor’s Corporate Secretary, Amkor Technology, Inc., 2045 East Innovation Circle, Tempe, Arizona 85284. You should also be aware of certain other requirements you must meet to have your proposal brought before the 2025 Annual Meeting. These requirements are explained in Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and in the Bylaws.

We have retained the services of Computershare Trust Company, N.A. to aid in the distribution of our Annual Meeting materials to brokers, bank nominees, and other institutional owners. Proxies may also be solicited by certain of Amkor’s officers and regular employees, without additional compensation, in person or by telephone or facsimile.

PROPOSAL ONE

ELECTION OF DIRECTORS

At the Annual Meeting, the terms of our 11 incumbent directors will expire. Each of these 11 incumbent directors has been nominated to stand for election to the Board of Directors this year. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the election of the 11 nominees named below. Each nominee has consented to be named as a nominee in this proxy statement and to serve as a director if elected. Should any nominee become unable or decline to serve as a director or should additional persons be nominated at the Annual Meeting, the proxy holders intend to vote all proxies received by them in such a manner as will assure the election of as many nominees identified below as possible (and, if additional nominees have been designated by the Board to fill any vacancies, in such manner as to elect such additional nominees). Our nominees for the election of directors include eight independent directors, as defined in the applicable rules for companies traded on Nasdaq. At the recommendation of the Nominating and Governance Committee of the Board (the “Nominating and Governance Committee”), the Board has selected the nominees to serve as directors for a one-year term until our next annual meeting and until their successor is duly elected and qualified or until their earlier resignation or removal. We expect that each nominee will be able to serve as a director.

Required Vote

Directors are elected by a plurality of votes cast, so the 11 candidates receiving the highest number of affirmative votes cast will be elected as directors. Votes withheld and broker non-votes are not counted toward the total votes cast in favor of a nominee.

Summary Information – Nominees for the Board of Directors

The Board considers various qualifications, characteristics, and other factors when evaluating individual directors, as well as the composition of the Board as a whole. As part of this process, the Board and the Nominating and Governance Committee review the particular experiences, qualifications, attributes, and skills of each nominee to determine if that person should stand for election to serve as a director of the Company.

Below is summary information, as of April 1, 2024, about the skills, experience, diversity, independence, tenure, and age for the 11 director nominees as a group, followed by biographies for the nominees. The biography for each of the nominees contains information regarding the person’s experience and director positions held currently or during the last five years and information regarding involvement in certain legal or administrative proceedings, to the extent applicable. The biographies also highlight the particular experiences, qualifications, attributes, or skills that caused the Nominating and Governance Committee and the Board to conclude that the person should be nominated to serve as a director of the Company.

The slate of director nominees includes diverse candidates with a broad range of skills and experience. The tenure of director nominees, with a majority of the nominees having served for fewer than 10 years, demonstrates the Board’s desire to balance experience and refreshment. The age of director nominees is fairly distributed over three age ranges, two of the 11 nominees self-identify as female, and three of the 11 nominees self-identify as ethnically diverse.

The Board unanimously recommends a vote FOR the election of each of the nominees for director below.

CORPORATE GOVERNANCE

Board and Committee Meetings

The Board of Directors held four meetings during 2023. All directors attended at least 75% of all Board of Directors and applicable committee meetings. The standing committees of the Board and membership are as follows:

Audit Committee

The Audit Committee is a separately-designated, standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. The current members of the Audit Committee are Mr. Carolin, Ms. McCourt, and Mr. Morse. Mr. Carolin currently serves as the Chairman of the Audit Committee.

Our Board of Directors has determined that each of Mr. Carolin, Ms. McCourt, and Mr. Morse meets the independence and financial sophistication requirements set forth in the Nasdaq listing standards and that each also qualifies as an “audit committee financial expert” as defined in SEC regulations. The responsibilities of the Audit Committee include, but are not limited to:

10

The Board of Directors has adopted a written charter for the Audit Committee, a copy of which is available on our website under the heading “Company Overview > Corporate Governance” at https://ir.amkor.com. During 2023, the Audit Committee met eight times. In executing their responsibilities, Audit Committee members regularly communicate with our management and independent registered public accounting firm.

Compensation Committee

The current members of the Compensation Committee are Messrs. Churchill, Carolin, Morse, and Watson. Mr. Churchill currently serves as the Chairman of the Compensation Committee. Our Board of Directors has determined that each of Messrs. Churchill, Carolin, Morse, and Watson meets the independence requirements set forth in the Nasdaq listing standards and SEC regulations. The responsibilities of the Compensation Committee include, but are not limited to:

11

When appropriate, the Compensation Committee may form and delegate authority to subcommittees to carry out any of the responsibilities under its charter. In addition, periodically, or as deemed appropriate, the Compensation Committee shall: (i) review and discuss with the Board the Company’s philosophy, processes, and procedures for the consideration and determination of non-employee director compensation; and (ii) evaluate the amount and type of director compensation, including the allocation between cash and equity-based compensation. In its review of director compensation, the Compensation Committee may consider, among other information, comparative data, advice, and recommendations from independent compensation consultants, the Company’s management team, and other advisors.

The Compensation Committee’s executive compensation determinations are subjective and the result of its business judgment, which is informed by the experience of its members and input provided by its independent compensation consultant, our CEO (other than with respect to his own compensation), and other members of management. Our Corporate Secretary and our law and human resources departments support the Compensation Committee in recommending director compensation and creating director compensation programs. In addition, the Compensation Committee can engage outside advisors, experts, and others for further assistance.

The Compensation Committee conducted an assessment of its independent compensation consultant, Frederic W. Cook & Co., Inc. (“F.W. Cook”), with respect to the factors set forth in Nasdaq and SEC rules. As a result of such assessment, the Compensation Committee concluded that the work performed by F.W. Cook for the Compensation Committee in 2023 did not raise any conflicts of interest.

The Board has adopted a written charter for the Compensation Committee, a copy of which is available on our website under the heading “Company Overview > Corporate Governance” at https://ir.amkor.com. During 2023, the Compensation Committee met eight times.

The Board has adopted a written charter for the Nominating and Governance Committee, which is available on our website under the heading “Company Overview > Corporate Governance” at https://ir.amkor.com. During 2023, the Nominating and Governance Committee met eight times.

13

The Nominating and Governance Committee’s goal is to ensure that the Board of Directors is made up of individuals of high integrity, personal character, and ethical standards and that the Board reflects a diverse range of professional backgrounds and experience relevant to our business. In the biographies of each of the nominees to the Board described above, we highlighted the experiences and qualifications that were among the most important to the Nominating and Governance Committee and the Board in concluding that each such nominee should serve on our Board. The Nominating and Governance Committee determines the required selection criteria and qualifications of director nominees based upon the needs of our Company at the time nominees are considered. When evaluating a director nominee, the Nominating and Governance Committee considers, among other factors, the director nominee’s character, judgment, independence, age, expertise, length of service, other commitments, and diversity in experience and background, including (but not limited to) race, gender or gender identity, sexual orientation, professional background, and geographic and industry experience, and whether such factors will strengthen the Board’s collective qualifications, skills, and experience and enhance the Board’s performance of its responsibilities in the oversight of our business.

The Nominating and Governance Committee will consider the above factors, and uses the same process, for evaluating all director nominees, regardless of the original source of nomination. The Nominating and Governance Committee does not currently use the services of any third-party search firm to assist in the identification or evaluation of Board member candidates. The Nominating and Governance Committee may, however, use such services in the future as it deems necessary or appropriate.

It is the policy of the Nominating and Governance Committee to consider both recommendations and nominations from stockholders for candidates to the Board of Directors. Stockholders wishing to recommend a candidate for consideration by the Nominating and Governance Committee for election to the Board of Directors can do so by writing to our Corporate Secretary at our principal executive office. Stockholders must provide (i) such candidate’s name, home address, and business address, (ii) a representation that the nominating person intends to appear in person or by proxy at the meeting to nominate the candidate, (iii) if known, the class and total number of shares of Amkor stock beneficially owned by the candidate, (iv) the total number of shares of Amkor stock that will be voted by the nominating stockholder for such candidate, (v) a description of all arrangements or understandings between the nominating person and the candidate and any other person (naming such person) pursuant to which the nomination is being made, (vi) detailed biographical data and qualifications, including such candidate’s age, principal occupation, and other information required to be disclosed in solicitations of proxies for election of directors pursuant to the Exchange Act, applicable Nasdaq listing standards, and other applicable law, (vii) written indication of the candidate’s willingness to serve if elected, (viii) the name and address of the nominating person and any other beneficial owner of such stock, (ix) the class and number of shares of Amkor stock owned by the nominating person and any other beneficial owner of such stock, and (x) a representation whether the nominating person or any other beneficial owner intends, or is part of a group which intends, to deliver a proxy statement and/or form of proxy to holders of at least the percentage of Amkor’s outstanding stock required to elect the candidate and/or otherwise to solicit proxies from stockholders in support of the nomination. Nominations for consideration at the 2025 Annual Meeting must be received by our Corporate Secretary no earlier than January 14, 2025 and no later than February 13, 2025.

Director Independence

The Board of Directors has determined that each of Messrs. Alexander, Carolin, Churchill, Liao, Morse, Tily, and Watson and Ms. McCourt is independent under the Nasdaq listing standards and SEC rules. In reaching a determination that Mr. Churchill is independent under the Nasdaq listing standards and SEC rules, the Board of Directors considered certain relationships between entities affiliated with Mr. Churchill and entities affiliated with Mr. Kim. These relationships include transactions, investments, or partnerships in which Mr. Churchill and Mr. Kim, or entities affiliated with them, have a direct or indirect financial interest. None of these relationships involved Amkor. The Board determined that Mr. Churchill satisfies the independence requirements set forth by both Nasdaq and the SEC. In reaching a determination that Mr. Morse is independent under the Nasdaq listing standards and SEC rules, the Board considered investments which Mr. Kim has in funds affiliated with an entity

14

in which Mr. Morse has an interest. These investments do not involve Amkor. The Board determined that Mr. Morse satisfies the independence requirements set forth by both Nasdaq and the SEC.

Communications with the Board of Directors

We have a process by which our stockholders can send communications to the Board, and that process was designed to enable the Board or individual directors, as applicable, to hear the views of our stockholders so that appropriate responses can be provided to our stockholders in a timely manner. Stockholders may communicate with the Board of Directors by writing to us at Amkor Technology, Inc., Attention: Corporate Secretary, 2045 East Innovation Circle, Tempe, Arizona 85284. Stockholders who would like their submission directed to a particular Board member may so specify, and the communication will be forwarded, as appropriate.

Corporate Governance Guidelines and Codes of Ethics

Our Board has adopted the Corporate Governance Guidelines, the Code of Business Conduct, which applies to all of our officers and employees worldwide, and the Director Code of Ethics, which applies to our directors. These documents are available on our website under the heading “Company Overview > Corporate Governance” at https://ir.amkor.com.

Board Leadership Structure

As part of its review of Amkor’s overall corporate governance practices, the Board of Directors periodically reviews its leadership structure. James J. Kim, Amkor’s founder, serves as the Executive Chairman of the Board of Directors. Amkor has a separate President and Chief Executive Officer, Giel Rutten, who is also a member of the Board of Directors. As a result of this structure, Amkor continues to benefit from Mr. Kim’s extensive experience in the semiconductor industry and management expertise based on his longstanding leadership role. Amkor also benefits from the expertise and broad management experience that our President and Chief Executive Officer, Mr. Rutten, brings to the Board.

Susan Y. Kim serves as Executive Vice Chairman of the Board. In this role, she assists the Chairman of the Board, presides over meetings of the Board in the absence of the Chairman, works closely with the Company’s senior executives in formulating Company strategy, and performs such other duties and responsibilities as set forth in the Bylaws or determined by the Board or the Chairman from time to time.

The Board has established the position of Lead Independent Director of the Board. The Lead Independent Director is responsible for coordinating the activities and agenda for the Board’s independent directors, serving as liaison between the Chairman and the Board’s independent directors, advising the Chairman regarding the flow of information from management necessary for the independent directors to effectively and responsibly perform their duties, consulting with the Chief Executive Officer regarding any concerns of the other directors, consulting with significant stockholders and other interested parties when appropriate, and such other responsibilities as set forth in the Corporate Governance Guidelines. The independent directors have designated Mr. Churchill to serve as Lead Independent Director of the Board.

We believe this Board structure is effective for Amkor and reflects an appropriate allocation of leadership responsibilities.

Executive Sessions

Consistent with our Corporate Governance Guidelines, the non-employee directors of the Board regularly hold executive sessions. The Audit Committee, in accordance with its charter, meets separately with our Chief Financial Officer throughout the year to review our financial affairs and meets separately in sessions with our independent registered public accounting firm, internal auditors, general counsel, and other members of

15

management at such times as the Audit Committee deems appropriate to fulfill its responsibilities under its charter. The Nominating and Governance Committee and the Compensation Committee also meet in executive session as deemed appropriate.

Risk Oversight

The Board is responsible for overseeing Amkor’s risk management process and views risk oversight as one of the important functions it performs. While the Board is ultimately responsible for risk oversight, Board committees assist the Board in administering and fulfilling this oversight responsibility through periodic meetings and discussions with management and Company advisors and report to the full Board with respect to certain categories of risk. With the assistance of the Nominating and Governance Committee, the Board has identified certain categories of risk to the Company, assigned oversight responsibility with respect to those risks to the Board as a whole, and delegated to its committees specific categories of risk based on the particular functions and responsibilities of such committees. The Board’s role in risk oversight has not affected its leadership structure.

As part of its overall responsibility for risk oversight, the Board directly oversees, among other areas, business strategy, customer and industry trends, financial performance, liquidity and capital expenditures, operations, insurance coverage, intellectual property, research and development, labor and human resources, and litigation. Senior management regularly, and at least annually, briefs the Board regarding cybersecurity and other information security matters relevant to the Company. The Audit Committee is responsible for, among other areas, reviewing the Company’s practices with respect to cybersecurity, information security, and financial risk oversight, which includes overseeing risks related to financial reporting and accounting, internal controls, disaster recovery, fraud, and taxes. The Compensation Committee assesses and monitors risks related to our compensation practices and other related areas. The Nominating and Governance Committee has responsibility for oversight of risks related to, among other areas, ESG and the Company’s corporate governance policies and practices that help position the Board to effectively carry out its risk oversight responsibility.

Amkor’s management is responsible for day-to-day risk management, which includes administration of the Company’s Enterprise Risk Management Program (the “ERM Program”). The ERM Program was instituted to formalize a practice for identifying and assessing the risks to Amkor’s business and to provide a top-down, holistic view of the risks that affect Amkor’s ability to achieve its objectives. Management’s ongoing risk management responsibilities also include identifying, evaluating, and addressing potential risks that may exist at the enterprise, strategic, financial, and operating levels and the development of processes for mitigating these risks. At periodic meetings of the Board and its committees and in other meetings and discussions, management reports to, and seeks guidance from, the Board and its committees, as applicable, with respect to matters that could affect the Company’s risk profile, strategic plans, risk mitigation strategies, and other aspects of the Company’s business. The Board oversees and monitors management in the execution of its risk oversight role. We believe that our Lead Independent Director’s understanding of our business, his specific knowledge and experience in corporate governance and legal areas relevant to our business, and his service on other boards of directors enables him to appropriately support the Board in its efforts to oversee risks affecting the Company. Additionally, the Board has created a Strategic Oversight Role, the purpose of which is to provide additional strategic oversight of the management and business of the Company with respect to leadership transitions, strategic initiatives, business risk, and succession planning. The Board has appointed Mr. Tily to serve in the Strategic Oversight Role in his capacity as a director.

Annual Meeting Attendance

All directors are encouraged, but not required, to attend our annual meetings of stockholders. All of the directors who were serving on the Board at the time of the 2023 Annual Meeting of Stockholders (the “2023 Annual Meeting”) attended the 2023 Annual Meeting.

Certain Relationships and Related Transactions

Related Party Transactions

Since January 1, 2023, there have been no related party transactions that are required to be reported under SEC rules.

Review and Approval of Related Party Transactions

We have a written policy on related party transactions that governs all relationships and transactions in which we and our directors, executive officers, or their immediate family members are participants. As required under SEC rules, transactions between the Company and related persons that are determined to be directly or indirectly material to the related person must be disclosed in our proxy statement. Management is primarily responsible for the development and implementation of processes and controls to obtain information from our directors and executive officers with respect to transactions between the Company and related parties and determining, based on the facts and circumstances, whether a related party has a direct or indirect material interest in the transaction. In addition, pursuant to the Audit Committee’s charter, the Audit Committee reviews and approves related party transactions in accordance with Nasdaq rules. In the course of its review and approval of a disclosable related party transaction, the Audit Committee considers:

Any member of the Audit Committee who is a related party with respect to a transaction under review may not participate in the deliberations or vote regarding approval of the transaction, provided, however, that such director may be counted in determining the presence of a quorum at an Audit Committee meeting.

Compensation Committee Interlocks and Insider Participation

During 2023, the Compensation Committee consisted of Messrs. Churchill, Carolin, Morse, and Watson. No member of the Compensation Committee was an officer or employee of Amkor or any of Amkor’s subsidiaries during 2023 or had any relationship requiring disclosure under SEC regulations. None of the Compensation Committee members or our executive officers has served on the board of directors or on the compensation committee of any other entity whose executive officers served on our Board of Directors or on our Compensation Committee.

Anti-Hedging, Anti-Pledging, and Clawback Policies

The Company’s policies prohibit directors, officers, and employees from engaging in hedging or derivative transactions with respect to Company securities. The policies specifically identify as prohibited transactions short sales, failing to deliver sold securities, put or call options, swaps, spread bets, collars, and forward sales contracts. The policies also prohibit placing Company securities in a margin account or pledging Company securities as collateral for a loan. In addition, the Clawback Policy requires the Company to recoup all or a portion of an executive officer’s incentive-based compensation, including awards granted pursuant to the Amkor Technology, Inc. Amended and Restated Executive Incentive Bonus Plan (the “Executive Bonus Plan”) and performance-based equity awards granted under the Company’s stock incentive plans, if the Company is required

17

to restate its financial statements resulting in the Company’s financial performance being reduced (such that the incentive-based compensation or any portion thereof would not have been paid) and certain other requirements are met. For more information about the Clawback Policy, please refer to the “Compensation Discussion and Analysis” section of this proxy statement (the “CD&A”).

DIRECTOR COMPENSATION

Non-Employee Director Compensation Policy

Our director compensation program is designed to attract and retain highly qualified non-employee directors and to align their interests with the long-term interests of our stockholders. The Compensation Committee is responsible for reviewing the equity and cash compensation for directors on an annual basis and making recommendations to the Board if it determines changes are needed. The Compensation Committee periodically reviews and considers information from its independent compensation consultant regarding the amounts and types of compensation paid to non-employee directors at companies the Compensation Committee considers when assessing executive compensation. In February 2023, in connection with its periodic evaluation of our director compensation program, the Compensation Committee adopted the Amended and Restated Amkor Technology, Inc. Non-Employee Director Compensation Policy (as amended and restated, the “Director Compensation Policy”).

Annual Retainer and Fees

During 2023, non-employee directors received an annual cash retainer, which was paid quarterly, and certain directors received fees for serving in certain Board positions and for attendance at Board and committee meetings, in each case pursuant to the Director Compensation Policy. Cash retainers and the fees are pro-rated for directors whose service lasts for less than a year. The 2023 cash compensation structure for our non-employee directors under the Director Compensation Policy is set forth in the following table:

Notes

In addition to the cash retainer and fees described above, we also reimburse directors for travel and other reasonable out-of-pocket expenses incurred by them in attending Board and committee meetings. Directors who are also employees or officers of Amkor, including Mr. Kim, our Executive Chairman, and Mr. Rutten, our President and Chief Executive Officer, do not receive annual retainers or meeting fees for their service on our Board of Directors.

Equity Compensation

Upon re-election to the Board of Directors at the 2023 Annual Meeting, each non-employee director was granted an equity award of time-vested restricted stock units (“RSUs”) with a fair market value on the grant date of $185,000, rounded down such that only whole shares are issued, pursuant to the Director Compensation Policy and the terms of the Amkor Technology, Inc. 2021 Equity Incentive Plan (as amended, the “2021 Equity Plan”). Subject to the terms and conditions of the RSU award agreement for non-employee directors: (i) the RSUs will

19

vest in full on the earlier of the first anniversary of the grant date or the date of the Company’s first annual meeting of the stockholders immediately following the grant date; and (ii) upon the Company’s payment of a cash dividend, dividend equivalent units (“DEUs”) accrue with respect to the underlying RSUs, with DEUs representing additional RSUs subject to the same vesting provisions as the underlying RSUs.

Under our stock ownership guidelines, each non-employee director is expected to directly or indirectly own shares of our common stock equal in value to five times the annual cash retainer for non-employee directors. Each non-employee director is expected to achieve the ownership guideline within five years after the date on which such director became subject to the ownership guideline and to retain 50% of the after-tax shares of common stock acquired or retained upon the exercise of a stock option or vesting of a restricted stock award (“RSA”) or restricted stock unit until such director satisfies the stock ownership guidelines. As of December 31, 2023, all of our non-employee directors either owned more than the minimum level of our common stock or were otherwise in compliance with the stock ownership guidelines.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

The CD&A contains material information regarding our executive compensation program and explains the material factors underlying disclosures that are contained in this proxy statement with respect to the compensation of our Chief Executive Officer, our Chief Financial Officer, and our three most highly-compensated executive officers (other than the Chief Executive Officer and the Chief Financial Officer) for the year ended December 31, 2023 (collectively, “NEOs”), each of whom is identified below:

In addition to providing compensation information for 2023 for the NEOs listed above, certain sections of this CD&A contain 2023 compensation information for our Executive Chairman, James J. Kim, where appropriate. Mr. Kim is an employee of the Company, but he is not an executive officer of the Company.

Executive Summary

The primary objectives of our executive compensation program are to attract highly qualified individuals for positions of substantial responsibility and to provide incentives for them to perform to the best of their abilities to promote the success of our business and build long-term value for our stockholders. The outsourced semiconductor packaging and test market is very competitive, and the Company’s operations and customers are global. To compete effectively, we need key senior management with the talent, leadership, and commitment to manage and operate our business, develop effective business strategies, differentiate our products and services, and anticipate and respond effectively to new challenges. To achieve these objectives, we offer a competitive compensation package consisting primarily of base salary, performance-based annual cash bonus opportunities, and equity-based awards.

In determining the compensation of our NEOs for 2023, the Compensation Committee considered the tenure of the NEOs in their current roles, individual performance, the value of individual unvested equity holdings, prior equity awards, the economic environment, the Company’s outlook for 2023 and its capital investments in future areas of growth, the Company’s financial results, the highly competitive nature of the Company’s industry, the Company’s international scope, and compensation data provided from time to time by the Compensation Committee’s independent compensation consultant. The Compensation Committee recognizes the need to attract, retain, and motivate a team of highly qualified and dedicated senior executives who are critical to the long-term success of the Company.

The Compensation Committee also considers the results of the Company’s advisory vote regarding the compensation of our NEOs, which is held on an annual basis consistent with the preference expressed by our stockholders. A substantial majority of our stockholders approved the compensation of our 2022 named

23

executive officers at the 2023 Annual Meeting, with more than 80% of the votes cast being in favor of approval. We view the result of this non-binding vote as an indication that our stockholders are generally supportive of our executive compensation program and policies.

Objectives of Our Executive Compensation Program

The objectives of our executive compensation program guide our Compensation Committee in designing pay packages with a mix of fixed and variable compensation to enable the Company to recruit, motivate, and retain key executives while maintaining a competitive cost structure. The Compensation Committee reviews proposed compensation packages with our Chief Executive Officer in determining compensation packages for our key executives (other than our Chief Executive Officer). The Compensation Committee and Chief Executive Officer also consult with the Executive Chairman.

Given the competitive and highly cyclical nature of our business, the Compensation Committee retains the flexibility to design an executive compensation structure that allows for a mix of cash, equity, and other forms of compensation (e.g., benefits and post-termination compensation), which meets the overall objectives of our executive compensation program. The Compensation Committee does not target a specific market level nor does it have an intended level for short-term versus long-term and cash versus non-cash compensation as a percentage of a NEO’s overall compensation opportunity. Instead, the Compensation Committee retains the flexibility to allocate compensation opportunities within these categories as it deems appropriate to achieve our overall compensation objectives.

Historically, the Compensation Committee and our Chief Executive Officer, in consultation with our Executive Chairman, have evaluated and monitored the effectiveness of our overall executive compensation arrangements on an ongoing basis. The Compensation Committee retains F.W. Cook to assist with reviewing the Company’s compensation structure for executives, including base salaries, performance-based annual cash bonuses, and equity incentive programs, and the selection of comparison companies for providing data to be used when evaluating our executive compensation arrangements. The Compensation Committee has considered the data provided by its compensation consultant from time to time as part of its determination of whether the overall level of compensation for each of our NEOs is reasonable in light of market conditions. The Compensation Committee does not use the data to establish any element of compensation at a particular benchmark or percentile level.

The Compensation Committee reviews and approves the compensation for our executive officers, including our Chief Executive Officer. It is the practice of the Compensation Committee to review with the other independent directors and the Executive Chairman our Chief Executive Officer’s compensation. In setting our executive officers’ overall compensation, the Compensation Committee generally considers a variety of factors related to the Company’s performance, including, in the case of our 2023 annual bonus program for executives, projections for continued growth in 2023, the Company’s strong performance in 2022, and balancing incentives for revenue with incentives for operating income.

The Company has entered into Executive Severance Agreements with Mr. Rutten and each of our U.S.-based NEOs (the “Executive Severance Agreements”). The Compensation Committee believes that the Company’s post-termination compensation and related arrangements with our NEOs are aligned with a normal market range of practices related to, and consistent with, the principal objectives of our compensation programs. For more information about the Executive Severance Agreements, please refer to the “Post-Termination Compensation” subsection of this CD&A and the “Employment, Severance, and Change in Control Arrangements” section of this proxy statement.

Compensation of Our Chief Executive Officer

As previously disclosed, in recognition of Mr. Rutten’s achievements in driving Company performance and stockholder value and the Board’s desire to retain Mr. Rutten as President and Chief Executive Officer, the

24

Company entered into an employment offer letter with Mr. Rutten in June 2020 setting forth the terms of his employment, which was amended by his Executive Severance Agreement in November 2022 (such offer letter, as amended by Mr. Rutten’s Executive Severance Agreement, the “Rutten Agreement”). The Company also granted a mix of options and RSAs in 2020, with three-year quarterly vesting that reflected the majority of Mr. Rutten’s equity compensation awards during 2020, 2021, and 2022.

The Compensation Committee and Executive Chairman created a 2023 compensation program for Mr. Rutten intended to provide a new incentive for his continued service, recognizing that the June 2020 equity awards provided to Mr. Rutten upon his promotion to President and Chief Executive Officer had been earned and were fully vested as of July 2023. The 2023 total compensation provided to the CEO, as reported in the Summary Compensation Table, was designed to be highly performance based, with approximately 73% of target equity awards at risk for achievement of multi-year earnings per share or for execution of strategies related to the ramp of new operations in the Company’s new facility in Vietnam and related to expanding the Company’s advanced packaging capacity for 2.5D technology. The material elements of Mr. Rutten’s compensation are summarized below.

Base Salary. Mr. Rutten’s base salary is periodically adjusted at the discretion of the Board. For 2023, his annual base salary was $1,000,000.

Annual Incentive Bonus. Subject to the terms and conditions of the Executive Bonus Plan, Mr. Rutten is eligible each year for a cash bonus with a target amount equal to 135% of his then-current salary.

Equity Awards. The Compensation Committee sets Mr. Rutten’s equity compensation after consideration of the value of his previous equity awards, new market data for chief executive officers in similar companies, and his performance as the Chief Executive Officer of the Company. Entering 2023, Mr. Rutten had served as President and Chief Executive Officer of the Company during a period of significant stock price appreciation. Mr. Rutten was granted certain RSU awards and PSU awards in February 2023 and in December 2023. The combined values of the RSU and PSU awards in February 2023 and December 2023 resulted in approximately 73% of the chief executive officer’s target equity awards being contingent on the achievement of future performance goals.

On February 16, 2023, Mr. Rutten was granted 55,679 RSUs, subject to the terms and conditions of the Company’s form of RSU award agreement for employees under the 2021 Equity Plan (the “RSU Award Agreement”) and 167,037 PSUs, at target level of achievement and subject to the terms and conditions of the Company’s form of PSU award agreement for employees under the 2021 Equity Plan (the “PSU Award Agreement”). The number of PSU Awards that Mr. Rutten will ultimately earn from the February 2023 PSUs will be determined based on the achievement of a performance goal based on the Company’s two-year cumulative earnings per share for the 2023 and 2024 Performance Period (the “2023-2024 Performance Period”). Two-year cumulative earnings per share was chosen as a performance metric to require ongoing profit generation over multiple years and was set higher than prior performance to require profit growth. The Company believes that increasing multi-year earnings per share will benefit stockholders with stock price growth or other capital returns. The percentage of the February 2023 PSU awards earned can range from 0% to 200% of the stated target amount of PSUs, with the final amount to be determined no later than March 31, 2025. The funding schedule for Mr. Rutten was the same as for other NEOs (with linear interpolation when performance is between points shown):

On December 14, 2023, Mr. Rutten was granted 43,857 RSUs, which will vest in full on July 1, 2024 or in the event Mr. Rutten is terminated by the Company without “Cause” (as defined in the 2021 Equity Plan), subject to the terms and conditions of an RSU award agreement (the “Rutten RSU Award Agreement”), and 106,638

25

PSUs, subject to the terms and conditions of a PSU award agreement (the “Rutten PSU Award Agreement”). The PSU awards made to Mr. Rutten in December 2023 were in recognition that the equity awards granted to him in connection with his June 2020 promotion to President and Chief Executive Officer became fully vested during 2023 and also to reward and drive financial and operational performance related to critical and significant geographic expansion of the Company’s manufacturing footprint and to expanding the Company’s advanced packaging capacity in support of end markets with high growth potential. The December 2023 PSUs granted to Mr. Rutten will become fully vested based on the achievement of either of two performance goals during a performance period beginning on December 14, 2023 and ending on December 31, 2024 (the “2024 Performance Period”), except that these PSUs will become fully vested in the event of the termination of Mr. Rutten’s employment by the Company without Cause. The Company is not able to provide specific performance goals because it believes that providing them would result in competitive harm. The Company believes that the performance goals are set at rigorous but achievable levels.

Severance Terms. Upon termination of Mr. Rutten’s employment by the Company without “Cause” or by Mr. Rutten for “Good Reason,” each as defined in the Rutten Agreement, subject to the execution and non-revocation of a release of all claims against the Company, and subject to Mr. Rutten abiding by the terms of certain restrictive covenants, Mr. Rutten will be entitled to post-termination compensation under various scenarios. For more information about the post-termination compensation payable to our NEOs, please refer to the “Employment, Severance, and Change in Control Arrangements” and the “Potential Payments upon Termination or Change in Control” sections of this proxy statement.

Other Benefits. Mr. Rutten is eligible for housing-related and a transport allowance associated with his posting in Singapore, executive health insurance coverage, and participation in various other employee benefit plans and programs, as in effect from time to time, on the same terms and conditions as apply to the Company’s executive officers or Singapore-based personnel generally.

At-Will Employment. Mr. Rutten’s employment with the Company is on an at-will basis.

Risk Assessment

The Compensation Committee has reviewed and evaluated the Company’s executive compensation and general compensation policies and practices. The Compensation Committee concluded that the Company’s compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company. As part of that process, the Compensation Committee evaluated whether such policies and practices create risks that are reasonably likely to have a material adverse effect on the Company. The Compensation Committee considered a number of factors, including the key components of the Company’s compensation programs, the relative weighting of those components as part of overall compensation, and considerations enumerated by the SEC. Prior to the Compensation Committee’s review, members of the executive management team also reviewed the Company’s compensation policies and practices and considered whether those policies and practices are likely to encourage inappropriate risk-taking by executives or other employees.

Our Compensation Program Rewards Individual and Company Performance

Our compensation program is designed to reward high levels of performance at the Company and individual levels. Our key executive incentive compensation components currently consist of cash bonuses and equity grants, both of which are designed to reward our company-wide performance and superior individual performance. In addition, given the volatility of our industry and the impact that volatility has on our variable pay, we strive to provide competitive base salaries in order to ensure a baseline level of stable income and health and welfare benefits in order to promote the well-being of our executives.

Our Chief Executive Officer reviews the performance of each of his direct reports on an ongoing basis. Based on this continual assessment of performance, our Chief Executive Officer makes recommendations to the Compensation Committee regarding the compensation (other than his own) of our executive officers.

26

Our compensation program is designed to reward performance rather than longevity of service. We do not maintain a pension program for our NEOs. Our U.S.-based NEOs are eligible to participate in the 401(k) Plan, which is generally available to U.S. employees. All salary increases and non-benefit related compensation other than base salary are structured in a manner that rewards performance, not length of service.

Our long-term incentive program has historically consisted of grants of stock options, RSUs, and RSAs that vest over time and PSUs that vest based on the attainment of performance goals. The intrinsic nature of a stock option is that it will only provide value to the executives to the extent our stock price increases over the life of the stock option. RSAs and RSUs provide a base level of long-term incentive compensation vesting over time that promotes the retention of key employees and ties executive compensation to the creation of long-term stockholder value through appreciation in the Company’s stock price. The Compensation Committee believes that PSUs strengthen the link between executive pay and Company performance and reward executives for achievement of the Company’s long-term performance goals. The PSUs granted on February 16, 2023 (the “February 2023 PSUs”) allow up to a 200% target payout based on the degree to which a basic cumulative earnings per share performance goal is achieved for the 2023-2024 Performance Period. For the PSUs granted on February 24, 2022, the performance period began on January 1, 2022 and ended on December 31, 2023 (the “2022-2023 Performance Period”). The Company believes that increasing multi-year earnings per share will benefit stockholders with stock price growth or other capital returns.

On December 14, 2023, the Company made a special grant of PSUs to NEOs that become fully vested based on the achievement of either of two performance goals during the 2024 Performance Period. These performance goals are designed to incentivize achievement related to the geographic expansion of the Company’s manufacturing footprint and expanding the Company’s advanced packaging capacity in support of end markets with high growth potential. For discussion of the performance goals for the PSUs, please refer to the Grants of Plan-Based Awards Table.

Timing of Grants. The Compensation Committee has not granted, nor does it intend in the future to grant, equity awards to executives in anticipation of the release of material nonpublic information that is likely to result in changes to the price of our common stock, such as a significant positive or negative earnings announcement. In addition, discretionary equity awards may not be made during certain “blackout” periods established in connection with the public release of earnings information. Similarly, the Compensation Committee has not timed, nor does it intend in the future to time, the release of material nonpublic information based on equity award grant dates.

Elements of Our Compensation Program

The Company provides two main types of compensation: fixed compensation; and variable compensation. Fixed elements of compensation are not correlated directly to any measure of the Company’s performance and include such items as base salary, 401(k) Plan matching contributions, health and welfare benefits, post-termination compensation pursuant to the Executive Severance Agreements, and limited perquisites and supplemental benefits. Variable elements of compensation are based on performance and include such items as annual performance bonuses and equity awards, such as PSUs or other equity-based incentives.

Base Salary

The Compensation Committee believes that the primary purpose of base salaries is to provide a stable source of income in order to attract and retain key executives. We also use base salary increases to reward high performing executives and to recognize increases in the scope of an individual’s responsibilities. We seek to set base salaries at a level that is sufficient to be attractive to current and prospective executives. The primary factors we consider when setting base salaries include the experience and expertise of the individual, the value of the position to our organization and ongoing strategy, the competitive market environment, internal equity considerations, and the input of our Chief Executive Officer (with respect to other NEOs) and our Executive Chairman.

27

In February 2023, the Compensation Committee approved base salary increases for our NEOs as follows: Mr. Rutten’s base salary was increased from $950,000 to $1,000,000; Ms. Faust’s base salary was increased from $590,000 to $600,000; Mr. Rogers’ base salary was increased from $540,000 to $550,000; and Mr. Haghighi’s base salary was increased from $525,000 to $550,000.

In February 2024, the Compensation Committee approved base salary increases for our NEOs as follows: Ms. Faust’s base salary was increased from $600,000 to $610,000; Mr. Rogers’ base salary was increased from $550,000 to $560,000; Mr. Haghighi’s base salary was increased from $550,000 to $560,000; and Mr. Engel’s base salary was increased from $450,000 to $500,000.

Annual Incentive Opportunities

We have generally paid cash bonuses to our executives based on the executive’s performance and our financial results. Cash bonuses, if any, are typically paid in the year following the year during which performance was measured. The primary purpose of cash bonuses is to focus the attention of key executives on our operational and financial performance. In addition, our cash bonus program allows us to set individual and Company-wide goals that are viewed as critical to our overall success on an ongoing basis. This provides us with the flexibility to adapt our focus and goals as business priorities and executives’ roles change over time. Bonuses are paid to executives with respect to the financial performance goals for a given year only if the performance goals approved by the Compensation Committee are achieved. Furthermore, even if such performance goals are achieved, the Compensation Committee retains the discretion to reduce an executive’s earned bonus based on such factors as it determines relevant.

Bonus opportunities and related performance targets for the NEOs for 2023 were established by the Compensation Committee under the Executive Bonus Plan in February 2023. In setting the target bonus opportunities for 2023, the Compensation Committee considered, among other factors, alignment of executive compensation with creation of stockholder value, the Company’s anticipated growth in 2023, and balancing incentives for revenue with incentives for operating income. For 2023, the Executive Bonus Plan provided each participant with a target bonus amount that could be earned based on achievement of goals for the following performance measures: (i) Revenue (weighted at 35%); (ii) Operating Income (weighted at 35%); and (iii) Discretionary/Individual Performance (weighted at 30%). The weightings reflect a desire to reward profitable and balanced growth, as well as a recognition that measurement of financial performance exclusively does not capture the totality of NEO performance in a large multi-national enterprise with the Company’s international footprint and scope of operations. For purposes of the Executive Bonus Plan, Revenue and Operating Income were determined based on net sales and operating income (as defined under U.S. generally accepted accounting principles (“GAAP”)), respectively, as reported in our audited consolidated financial statements, to be adjusted for extraordinary items such as legal settlements and accruals, sales, costs, and other charges associated with mergers and acquisitions, and other items as approved by the Compensation Committee.

28

The following table sets forth the target bonus levels for 2023.

Notes

With respect to each of the Revenue and Operating Income performance measures under the Executive Bonus Plan for 2023:

With respect to the Individual Performance measure under the Executive Bonus Plan, an attainment percentage between 0% and 200% was assigned to each NEO based on the NEO’s individual performance during 2023.

For 2023, a NEO’s bonus under the Executive Bonus Plan was calculated based on the following formula:

[Base Salary] x [Target Bonus %] x [(Revenue Attainment % x 35%) + (Operating Income Attainment % x 35%) + (Individual Performance Attainment % x 30%)] = [Bonus Payout]

For 2023, the threshold performance goal for the Revenue performance measure under the Executive Bonus Plan was $6,400 million, the target was $7,200 million, and the maximum level of performance was $7,700 million. The Operating Income threshold performance goal was $600 million, the target was $720 million, and the maximum level of performance was $900 million.

A similar scale of 0% to 200% was set for the Individual Performance measure. The Revenue, Operating Income, and Individual Performance measures operated independently. In the event that the attainment for any performance measure was greater than the threshold but less than the target, or greater than the target but less than the maximum, the payout for such measure would be pro-rated on a straight-line basis. In all events, under the Executive Bonus Plan, the payout for each performance measure was capped at 200%, and participants were capped at an aggregate bonus equal to 200% of their target bonus amount.

29

In February 2024, the Compensation Committee confirmed the Revenue attainment for 2023, which was $6,503 million, and the Operating Income attainment for 2023, which was $470 million, resulting in an attainment for the Revenue and Operating Income components of 13% and 0%, respectively, in accordance with the pre-established payout formula. The Compensation Committee also considered the individual performance of each of our NEOs and Mr. Kim during 2023. In light of the Company’s achievement of several significant financial milestones during 2023, including market share growth, outperformance against the semiconductor industry, financial discipline and management, maintaining profitability in a cyclical downturn, expansion of the Company’s manufacturing footprint with advanced packaging capacity, progress on planning for a manufacturing facility in the United States, and progress on developing and implementing ESG initiatives, including a net-zero commitment, the Compensation Committee determined that achievement of the Individual Performance measure for each of our NEOs and Mr. Kim should be set at 200% of the potential target for 2023, consistent with the maximum under the formula and recognizing that Individual Performance attainment only relates to 30% of the target Executive Bonus Plan award. As a result of these considerations, based on the level of achievement in 2023 and in accordance with the pre-established payout formula, the Compensation Committee approved below target bonuses for the NEOs and Mr. Kim as set forth below:

Long-Term Incentive Compensation

The Company has granted equity-based awards to executives from time to time, typically in the form of stock options, RSAs, RSUs, or PSUs. The primary purpose of granting equity-based awards is to align our executives and stockholders with a common goal of long-term stockholder value creation. The Compensation Committee believes that stock options issued with exercise prices equal to fair market value on the date of grant that have a time-based vesting requirement can be an effective retention and incentive tool because the stock options only produce value to the extent that the executive continues to be employed by us and the stock price increases, which in turn creates value for all stockholders. The Compensation Committee also believes that RSAs, RSUs, and PSUs provide a base level of long-term incentive compensation vesting over time that promotes the retention of key employees and ties executive compensation to the creation of long-term stockholder value through appreciation in the Company’s stock price or other appropriate performance measures.

The Chief Executive Officer typically consults with other senior executive officers, the Chairman of the Compensation Committee, and our Executive Chairman regarding his recommendations for long-term incentive awards to our executive officers (other than himself). The Compensation Committee, with the assistance of data provided periodically by its compensation consultant, reviews the recommendations from the Chief Executive Officer and makes awards as it deems appropriate. Although a number of factors are considered, equity awards granted to our executive officers are determined on a case-by-case and discretionary basis, rather than pursuant to a formula. Factors considered include individual performance potential, retention, the amount that vests annually, and competitive market-based compensation packages. Awards are typically granted to our executive officers each February and may also be granted at other times during the year, such as in connection with a promotion, when a newly hired executive begins employment with the Company or to incentivize achievement of specific operational or financial goals. The number of shares underlying equity awards granted to our Chief Executive Officer and the frequency of grants to him are determined in the discretion of the Compensation Committee. It is the practice of the Compensation Committee to review such grants to the Chief Executive Officer with the other independent members of the Board and the Executive Chairman.

30

On February 16, 2023, the Compensation Committee granted PSUs and RSUs under the 2021 Equity Plan to our Executive Chairman and our NEOs as follows: Mr. Kim, 27,839 PSUs and 9,279 RSUs; Mr. Rutten, 167,037 PSUs and 55,679 RSUs; Ms. Faust, 50,111 PSUs and 16,703 RSUs; Mr. Rogers, 22,271 PSUs and 7,423 RSUs; Mr. Haghighi, 22,271 PSUs and 7,423 RSUs; and Mr. Engel, 16,703 PSUs and 5,567 RSUs. For each of our Executive Chairman, Mr. Rutten, Ms. Faust, Mr. Rogers, Mr. Haghighi, and Mr. Engel, the aggregate value of the foregoing equity awards was allocated as 75% PSUs and 25% RSUs to emphasize the performance-based element that aligns with the two-year earnings per share goal underlying the PSUs. The allocation between these two forms of equity awards was to emphasize a performance-based requirement to earn equity awards rather than using equity as a retention-oriented incentive.

On December 14, 2023, the Compensation Committee granted PSUs and RSUs under the 2021 Equity Plan to our NEOs as follows: Mr. Rutten, 106,638 PSUs and 43,857 RSUs; Ms. Faust, 18,023 PSUs; Mr. Rogers, 8,260 PSUs; Mr Haghighi, 8,260 PSUs; and Mr. Engel, 8,260 PSUs. Such equity awards were granted as part of the 2023 compensation program to incentivize achievement of certain performance goals related to geographic expansion of the Company’s manufacturing footprint and expanding the Company’s advanced packaging capacity in support of high growth potential end markets.

Description of 2023 PSUs. Under the PSU Award Agreement, for the February 2023 PSUs granted to our Executive Chairman, Mr. Rutten, Ms. Faust, Mr. Rogers, Mr. Haghighi, and Mr. Engel under the 2021 Equity Plan, the number of February 2023 PSU awards that a recipient will ultimately earn will be determined based on the achievement of a performance goal based on the Company’s two-year cumulative earnings per share for the 2023-2024 Performance Period. Two-year cumulative earnings per share was chosen as a performance metric to require ongoing profit generation over multiple years and was set higher than prior performance to require profit growth. The Company believes that increasing multi-year earnings per share will benefit stockholders with stock price growth or other capital returns. The percentage of the February 2023 PSUs earned can range from 0% to 200% of the stated amount of PSUs, with the final amount to be determined no later than March 31, 2025, with receipt subject to the recipient’s continued employment through the date of determination. For additional information regarding the February 2023 PSUs, please refer to the Grants of Plan-Based Awards Table. The funding schedule was the same for all February 2023 PSUs granted to Mr. Rutten and the NEOs (with linear interpolation when performance is between the points shown):

The Company also issued PSUs in December 2023 to Mr. Rutten, Ms. Faust, Mr. Rogers, Mr. Haghighi, and Mr. Engel. PSU earnout will be based on the achievement of either of two internal performance goals related to geographic expansion of the Company’s manufacturing footprint and expanding the Company’s advanced packaging capacity in support of end markets with high growth potential during the 2024 Performance Period. The Company is not able to provide specific performance goals because it believes that providing them would result in competitive harm. The Company believes that the performance goals are set at rigorous but achievable levels. For additional information regarding the 2023 PSUs, please refer to the Grants of Plan-Based Awards Table. For a discussion of the material post-employment compensation provisions under the PSU Award Agreement, and the Rutten PSU Award Agreement, please refer to the “Employment, Severance, and Change in Control Arrangements” section of this proxy statement.

Description of 2023 RSUs. Under the RSU Award Agreement, the RSUs granted in February 2023 will vest in four equal installments beginning on February 16, 2024 and ending on February 16, 2027, subject to the recipient’s continued employment with the Company at the time of vesting. Under the Rutten RSU Award Agreement, the RSUs granted to Mr. Rutten in December 2023 will vest in full on July 1, 2024, subject to Mr. Rutten’s continued employment with the Company at the time of vesting, except in the event Mr. Rutten is terminated by the Company without Cause (as defined in the 2021 Equity Plan), in which case the RSUs will become fully vested. For a discussion of the material post-employment compensation provisions under the RSU

31

Award Agreement, and the Rutten RSU Award Agreement, please refer to the “Employment, Severance, and Change in Control Arrangements” section of this proxy statement.

Performance Attainment - 2022 PSUs. On February 24, 2022, the Compensation Committee awarded PSUs to our Executive Chairman and our NEOs, other than Mr. Rutten. The 2022 PSUs were earned based on 2022 and 2023 cumulative two-year earnings per share relative to a goal set at the start of 2022. The target number of 2022 PSUs was as follows: Mr. Kim, 32,244 PSUs; Ms. Faust, 41,197 PSUs; Mr. Rogers, 22,570 PSUs; Mr. Haghighi, 22,570 PSUs; and Mr. Engel, 11,285 PSUs. The 2022 PSUs vested based on the level of achievement of an earnings per share performance goal for the 2022-2023 PSU Performance Period according to the following terms:

The threshold, target, and maximum two-year cumulative earnings per share performance goals for the 2022 PSUs were $4.54, $6.49, and $10.38, respectively. In all events, the maximum number of 2022 PSUs earned was capped at 200% of the PSUs awarded. On February 20, 2024, the Compensation Committee determined that the two-year cumulative earnings per share for the 2022-2023 Performance Period was $4.59, or 71% of the target earnings per share for the 2022-2023 PSU Performance Period, which funded a formulaic payout of 51% for the 2022 PSUs. Accordingly, 51% of the target number of 2022 PSUs awarded to recipients vested in accordance with the terms of the applicable PSU Award Agreement.

2024 Long-Term Incentive Awards. In February 2024, the Compensation Committee granted long-term incentive awards in the form of RSUs and PSUs to our Executive Chairman and the NEOs pursuant to the 2021 Equity Plan. The RSUs granted in February 2024 will vest in three equal installments on the anniversary of the grant date subject to the recipient’s continued employment with the Company at the time of vesting. The PSUs granted in February 2024 are divided evenly between PSUs based on earnings per share in 2024, 2025, and 2026, and PSUs based on relative total shareholder return over a three-year period, compared to the components of the PHLX Semiconductor Index (the “SOX”) over a three-year period.

Post-Termination Compensation

Executive Severance Agreements

As discussed elsewhere in this CD&A, in November 2022, the Company entered into the Executive Severance Agreements with each of its NEOs (in February 2023 for Mr. Engel). For details regarding the post-termination compensation payable to our NEOs, please refer to the “Compensation of Our Chief Executive Officer” subsection of this CD&A and the “Employment, Severance, and Change in Control Arrangements” and “Potential Payments upon Termination or Change in Control” sections of this proxy statement.

Rationale for Post-Termination Compensation Arrangements

Given the uncertainty inherent in change in control transactions, the Compensation Committee believes that it is in the best interests of our stockholders for management to remain neutral as to whether there is a change in

32

control transaction, through the use of severance. Management may be less inclined to resist change in control transactions that are in the best interests of our stockholders when they have the added security that comes with change in control arrangements. Additionally, the Compensation Committee believes that our post-termination compensation and related arrangements with our NEOs are aligned with existing market practices. The severance benefits for each NEO under the applicable Executive Severance Agreement are predicated upon the NEO being terminated without Cause (i.e., “double trigger”). These benefits are also available to Mr. Rutten in the event that he resigns for Good Reason, and to our other NEOs under similar circumstances in the event of a Change in Control. For those NEOs, our change in control provisions do not include excise tax gross-ups, and our severance benefits are subject to the NEO signing a general release and waiver and complying with certain restrictive covenants. For all NEOs, the restrictive covenants include non-solicitation and (except for Mr. Haghighi, who resides in California) non-competition obligations for 12 months following a separation from service and certain non-disparagement, confidentiality, and intellectual property assignment obligations for an indefinite period. We believe that the restrictive covenants we have with our NEOs serve the best interests of the Company and its stockholders.

Our equity award agreements also generally provide for partial (in the case of PSUs) or full (in the case of all other equity awards) vesting of underlying equity awards in the event of a NEO’s death or disability. Similarly, the RSU Award Agreement and PSU Award Agreement provide for partial vesting of underlying equity awards in the event of a NEO’s retirement. The Compensation Committee approved these provisions to recognize the unique impact of the leadership decisions made by our NEOs on the long-term direction of the Company.

With the exception of the post-termination compensation arrangements discussed in this CD&A, we do not have any employment, severance, change-in-control, or other post-employment compensation arrangements in place with any of our NEOs.

Other Compensation Elements

Health, Welfare, and Retirement Benefits. Our NEOs are eligible to participate in health and welfare benefit programs that are generally available to all salaried, full-time employees, as determined by, and subject to, the laws of the country of their employment. Additionally, the 401(k) Plan is a tax-qualified 401(k) savings plan that, subject to Internal Revenue Service limits, allows U.S. employees to contribute a portion of their cash compensation on a pre-tax basis to an account that is eligible to receive matching contributions. We match employee contributions at a rate of 100% of the amount of compensation deferred by each participant, up to a maximum matching contribution of $10,000 per year. All of the NEOs participate in the 401(k) Plan except for Mr. Rutten, who lives and works in Singapore.

Perquisites and Personal Benefits. We have a relocation program and provide certain payments and benefits under this program to all eligible employees, including the NEOs. A housing allowance, tax gross-up, tax equalization, and similar benefits may also be available for employees on expatriate assignments. In addition to the health and welfare benefits generally available to all salaried, full-time employees, the Company also pays for our executive officers to obtain an annual medical screening and offers a plan with increased health insurance coverage to our CEO.

Although they comprise a small portion of the total compensation for our NEOs, the purpose of these benefits is to promote the continuous well-being of our executives and to ensure that they are able to devote their attention to our ongoing success.

Stock Ownership Guidelines

In order to align the interests and objectives of our directors and officers with those of our stockholders, and to further promote the Company’s longstanding commitment to sound corporate governance, the Company has

33

established guidelines for Company stock ownership and retention. Each NEO is expected to own shares of our common stock equal in value to a multiple of such NEO’s salary. The Chief Executive Officer is expected to hold 300% of his annual base salary. Each other NEO is expected to hold 100% of the NEO’s annual base salary. Executive officers have five years from the date on which they first become subject to the stock ownership guidelines to achieve this ownership level. As of March 1, 2024, each NEO either owned more than the minimum stock ownership level, or was otherwise in compliance with, the Company’s stock ownership guidelines.

Anti-Hedging, Anti-Pledging, and Clawback Policies

On November 15, 2023, pursuant to applicable Nasdaq and SEC requirements, the Company adopted the Clawback Policy, which requires the Company to recoup all or a portion of a participant’s incentive-based compensation, including awards granted pursuant to the Executive Bonus Plan and the 2021 Equity Plan, if the Company is required to restate its financial statements resulting in the Company’s financial performance being reduced (such that the incentive-based compensation or any portion thereof would not have been paid) and certain other requirements are met. Pursuant to the Clawback Policy, in the event that the Company is required to prepare an Accounting Restatement (as defined in the Clawback Policy), the Company will recover the amount of any Erroneously Awarded Compensation (as defined in the Clawback Policy) received by any current or former executive officer of the Company with respect to the three-year period before such Accounting Restatement.

The Company’s policies also prohibit directors, officers, and employees from engaging in hedging or derivative transactions with respect to Company securities. For a description of these anti-hedging and anti-pledging policies, please refer to the “Corporate Governance” section of this proxy statement.

Tax and Accounting Considerations

The Tax Cuts and Jobs Act (the “Tax Act”) eliminated the “performance-based compensation” exemption from the $1 million cap on deductibility under Section 162(m) of the Internal Revenue Code of 1986, as amended, effective January 1, 2018. Notwithstanding the Tax Act, the Compensation Committee retains the flexibility to pay compensation that is not entirely deductible where the Compensation Committee determines doing so to be appropriate. For accounting purposes, time-based equity awards are measured at their grant date fair value with the resulting compensation expense recognized ratably over the service period, which is generally the vesting period of the award.

Compensation Committee Report

The Compensation Committee has reviewed and discussed this CD&A with management. Based on such review and discussion, the Compensation Committee recommended to the Board of Directors that the CD&A be included in this proxy statement, and such recommendation was approved by the Board of Directors.
