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.

Q:	How can I attend the Annual Meeting?

We have determined that the Annual Meeting will be held in a virtual meeting format only, via the internet. You may attend the Annual Meeting, submit questions, and vote your shares electronically during the Annual Meeting via live webcast at meetnow.global/MRHAM2U. Stockholders as of the Record Date who attend and participate in the virtual Annual Meeting will have an opportunity to submit questions live via the internet during a designated portion of the Annual Meeting. You will need the 15-digit control number printed on your proxy card to submit questions or otherwise participate in the Annual Meeting.

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.

Q:	What may I vote on?

The election of 11 nominees named in this proxy statement to serve on our Board of Directors (“Proposal One”);

An advisory vote to approve the compensation of our named executive officers (“Proposal Two”);

The ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2024 (“Proposal Three”); and

Shareholder proposal to report on effectiveness of the company’s diversity, equity, and inclusion efforts (“Proposal Four”).

Q:	How does the Board recommend I vote on the proposals?

A:	The Board recommends a vote FOR each of Proposal One, Proposal Two, and Proposal Three and a vote AGAINST Proposal Four.

Q:	Who is entitled to vote?

A:	Stockholders of record as of the close of business on the Record Date are entitled to vote at the Annual Meeting. Each stockholder is entitled to one vote for each share of common stock held on the Record Date. As of the Record Date, 246,155,251 shares of Amkor’s common stock were outstanding.

Q:	How do I vote?

A:	Registered holders may vote:

•

At the virtual Annual Meeting, by following the instructions at meetnow.global/MRHAM2U, using the 15-digit control number printed on your proxy card;

•

By mail, by signing and dating each proxy card you receive and returning it in the postage-prepaid envelope; or

•

By internet or telephone, following the instructions on the proxy card.

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:

•

will not have the authority to exercise discretion to vote your shares with respect to Proposal One, Proposal Two, or Proposal Four because NYSE rules treat those matters as non-routine; and

•

will have the authority to exercise discretion to vote your shares with respect to Proposal Three because that matter is treated as routine under NYSE rules.

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.

Q:	What is the voting requirement to approve each of the proposals?

Under Proposal One, the 11 directors receiving the highest number of affirmative votes cast will be elected. The approval, on an advisory basis, of Proposal Two and the approval of Proposal Three and Proposal Four each requires the affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote on that proposal at the Annual Meeting. Abstentions are not counted in the tally of votes FOR or AGAINST a proposal but are counted as present in person or represented by proxy and entitled to vote. A withheld vote is the same as an abstention.

Q:	What is a “quorum”?

A:	A “quorum” is a majority of the outstanding shares entitled to vote at a meeting being present at the meeting or represented by proxy. There must be a quorum for a meeting to be held and action to be validly taken. If

you submit a properly executed proxy, even if you abstain from voting, then your shares will be counted toward the presence of a quorum at the Annual Meeting. If a broker indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular matter (resulting in a broker non-vote), those shares will not be counted as present or represented for purposes of determining whether stockholder approval of that matter has been obtained but will be counted for purposes of establishing a quorum. Virtual attendance at our Annual Meeting constitutes presence in person for purposes of establishing a quorum.

Q:	How can I change my vote or revoke my proxy?

If you are a registered holder, you have the right to revoke your proxy and change your vote at any time before the Annual Meeting by: (i) submitting a later-dated proxy by mail, internet, or telephone; (ii) mailing a written notice of revocation to Amkor Technology, Inc., Attention: Corporate Secretary, 2045 East Innovation Circle, Tempe, Arizona 85284; or (iii) attending and voting at the virtual Annual Meeting. Attendance at the Annual Meeting, in and of itself, will not constitute a revocation of a proxy. If your shares are held by a bank, brokerage firm, or other record holder, please contact that firm or holder for instructions on how to change your vote or revoke your proxy.

Q:	What does it mean if I get more than one proxy card?

A:	It means you hold shares registered in more than one account. Submit all proxies to ensure that all your shares are voted.

Q:	Who can attend the Annual Meeting?

All stockholders as of the Record Date and persons holding a valid proxy for the Annual Meeting may attend the Annual Meeting via live webcast by following the instructions at meetnow.global/MRHAM2U. All attendees will need the 15-digit control number printed on their proxy card in order to be admitted to the Annual Meeting.

Q:	How will voting on any other business be conducted?

Although we do not know of any business to be considered at the Annual Meeting other than the proposals described in this proxy statement, if any other business is properly presented at the Annual Meeting, your proxy gives authority to James J. Kim, Amkor’s Executive Chairman, and Giel Rutten, Amkor’s President and Chief Executive Officer, to vote your shares on such matters at their discretion.

Q:	How and when may I submit proposals for the 2025 Annual Meeting of Stockholders?

To have your proposal included in our proxy statement and form of proxy for the Company’s 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”), we must receive your written proposal no later than December 13, 2024. You may submit proposals after this date for consideration at the 2025 Annual Meeting, but we are not required to include any proposal submitted after this date in the proxy statement for the 2025 Annual Meeting or the related proxy card.

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.

Q:	Who is soliciting proxies?

A:	This solicitation of proxies is made by the Board of Directors. All related costs will be borne by Amkor.

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 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.

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

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

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:

•

whether the transaction is in the best interest of the Company and its stockholders;

•

the nature of the related party’s interest in the transaction;

•

the material terms of the transaction, including, without limitation, the amount and type of transaction;

•

the importance of the transaction to the related party;

•

whether the transaction would impair the judgment of a director or executive officer to act in our best interest; and

•

any other matters the Audit Committee deems appropriate.

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

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:


Annual Retainer for Board Members	$	60,000
Additional Annual Retainers:
Lead Independent Director	$	25,000
Executive Vice Chairman	$	150,000
Strategic Oversight Role	$	75,000
Audit Committee Chairman	$	25,000
Compensation Committee Chairman	$	15,000
Nominating and Governance Committee Chairman	$	10,000
Fee per Board and Committee meeting – regular (quarterly) meetings (1)	$	2,000
Fee per Board and Committee meeting – other (1)	$	1,000

Notes

(1)	Directors were compensated for attendance at all regular meetings of the Board and its committees at a rate of $2,000 per meeting and were compensated for attendance at all other meetings at the rate of $1,000 per meeting.

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

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.

Notes

(1)

Mr. Kim is an employee and is compensated for his services as our Executive Chairman of the Board as an employee, rather than as a non-employee director. He does not earn fees for his service as a member of the Board. His compensation is approved annually by the Compensation Committee. Mr. Kim’s 2023 non-equity incentive compensation opportunity was based on the same performance criteria approved by the Compensation Committee for our executive officers, as described below in the CD&A. Mr. Kim received an equity award consisting of RSUs and performance-vested restricted stock units (“PSUs”) in 2023 in connection with his service as an employee and is also provided health and welfare benefits generally available to our employees.

(2)

The amounts in the Stock Awards column reflect the aggregate grant date fair value of RSUs and PSUs granted during the year ended December 31, 2023, calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation -Stock Compensation (“FASB ASC 718”), which is derived using the closing price of our common stock on the date of grant and excluding the impact of estimated forfeitures related to service-based vesting conditions. Assumptions used in the calculation of these amounts are included in Note 2 to our Consolidated Financial Statements included in our Annual Report on Form 10-K filed with the SEC on February 16, 2024 (the “Form 10-K”) and are incorporated by reference herein. For a description of the vesting schedule relating to the RSUs awarded to

our directors, please refer to the “Director Compensation—Equity Compensation” section of this proxy statement. For the PSUs awarded to Mr. Kim, the valuation was based upon a 100% attainment, which represents the probable outcome of the performance conditions for those awards, consistent with the estimate of aggregate compensation cost to be recognized over the service period determined as of the grant date under FASB ASC 718. The value of the 2023 PSU awards at the grant date for Mr. Kim, assuming that the highest level of the performance conditions will be achieved, was $1,468,229. The amounts for the RSUs and (in the case of Mr. Kim only) PSUs reported in the table above reflect the accounting expense for these awards on the grant date and do not correspond to the actual value, if any, that will be recognized by the applicable director. The values for the RSUs and PSUs awarded to Mr. Kim and included in the Stock Awards column also reflect that, pursuant to the terms and conditions of the applicable equity award agreements, he does not have any dividend equivalent rights with respect to such RSUs and PSUs.

As compensation for his service as an employee, Mr. Kim received 9,279 RSUs and 27,839 PSUs in 2023. Pursuant to our Director Compensation Policy and upon re-election, our non-employee directors received an annual grant of RSUs having a fair market value on the grant date of $185,000 in 2023. As discussed in the “Director Compensation - Equity Compensation” section of this proxy statement, pursuant to the terms of the RSU award agreement for non-employee directors, upon the Company’s payment of a cash dividend, DEUs accrue with respect to the underlying RSUs, with each DEU representing an additional RSU and subject to the same vesting provisions as the underlying RSU. Total stock options outstanding as of December 31, 2023 for Amkor’s directors (other than Mr. Rutten, whose compensation information is provided in the Summary Compensation Table) are as follows: Mr. Kim — 450,000; Ms. Kim — 145,000; Mr. Alexander — 84,657; Mr. Carolin — 140,000; Mr. Churchill — 40,000; Mr. Liao — 60,000; Ms. McCourt — 20,000; Mr. Morse — 140,000; Mr. Tily — 20,000; and Mr. Watson — 160,000. As of December 31, 2023, Mr. Kim held 22,527 RSUs and 60,083 PSUs, and each of Amkor’s non-employee directors held 8,550 RSUs, which include rounded underlying DEUs accrued through December 31, 2023.
