PROXY STATEMENT

This proxy statement contains information related to our annual meeting of stockholders to be held on Thursday, May 7, 2026, beginning at 8:00 a.m., Pacific Time, via video conference, and at any adjournments or postponements of the meeting. The purpose of this proxy statement is to solicit proxies from the holders of our common stock for use at the meeting.

For information on how to vote your shares, see the instructions included on the proxy card and under “How to Vote” below. This solicitation is being made by the Board of Directors of TTM Technologies, Inc. (the "Company", "TTM", "we", "our" or "us").

General Information

ABOUT THE MEETING

Matters To Be Considered At The Meeting

The matters to be considered and voted upon at the meeting will be:

Voting Recommendations of The Board

Each of the recommendations of our Board of Directors is set forth together with the description of each item in this proxy statement. In summary, our Board of Directors recommends a vote (1) “FOR” the election of each of its three nominees for class II directors; (2) "FOR" approval of the TTM Technologies, Inc. Equity Advantage Match Plan; (3) “FOR” approval on an advisory, non-binding basis, of the compensation of the Company's named executive officers; (4) in favor of holding an advisory, non-binding vote every one (1) year to approve the compensation of the Company's named executive officers; and (5) “FOR” the ratification of the appointment of KPMG LLP as the Company's independent registered public accounting firm for the fiscal year ending December 28, 2026. If you sign and return your proxy card but do not specify how you want your shares voted, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of our Board of Directors.

Our Board of Directors does not know of any other matters that may be brought before the meeting nor does it foresee or have reason to believe that the proxy holders will have to vote for a substitute or alternate board nominee for director. In the event that any other matter should properly come before the meeting or any nominee for director is not available for election, the proxy holders will vote as recommended by the Board of Directors or, if no recommendation is given, in accordance with their best judgment.

Who May Vote

Only stockholders of record at the close of business on March 11, 2026, the record date for the annual meeting, are entitled to receive notice of the meeting and to vote the shares of our common stock that they held on that date at the meeting, and any postponements or adjournments of the meeting. Each outstanding share of common stock entitles its holder to cast one vote on each matter to be voted upon at the annual meeting.

How To Vote

Stockholder of Record. If you are the stockholder of record (that is, the shares are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC (formerly American Stock Transfer & Trust Company)), you may vote your proxy in one of two convenient ways:

Via the Internet: Go to www.voteproxy.com and follow the instructions. You will need the 11-digit control number that appears on your proxy card included with this proxy statement. This method of voting will be available starting March 28, 2026, and through 11:59 p.m., Eastern Time, on May 6, 2026.

By mail: If you wish to vote by traditional proxy card and did not receive one along with this proxy statement, you can receive a full set of materials at no charge through the Internet at https://investors.ttm.com/news-events/annual-stockholders-meeting, by telephone at (888) 776-9962 or (201) 299-6210 (for international callers), by sending an e-mail to help@equiniti.com (the subject line of your e-mail should contain the 11-digit control number that appears in the Notice Regarding the Availability of Proxy Materials you received) or go to https://us.astfinancial.com/OnlineProxyVoting/ProxyVoting/RequestMaterials. If you vote by traditional proxy card, mark your selections on the proxy card, date the card, and sign your name exactly as it appears on the card, then mail it in the postage-paid envelope enclosed with the materials. You should mail the proxy card in plenty of time to allow delivery to our transfer agent prior to the meeting.

Street Name Shares. If your shares are held in an account at a bank, broker or other institution, you are the beneficial owner of shares held in “street name,” and the Notice is forwarded to you by that institution. The institution holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to instruct that institution on how to vote the shares held in your account. You must instruct that institution in order for your shares to be voted, and that bank, broker or other institution is required to vote those shares in accordance with your instructions.

If you are a beneficial owner of shares held in street name and do not provide the institution that holds your shares with specific voting instructions, under the rules of the Financial Industry Regulatory Authority, the institution that holds your shares may generally vote on routine matters but cannot vote on non-routine matters. If you do not provide your bank, broker or other nominee with instructions on how to vote your street name shares on a non-routine matter, the institution that holds your shares will inform the inspector of election that it does not have the authority to vote on that matter with respect to your shares. This is generally referred to as a “broker non-vote.”

How To Change Or Revoke Your Vote

You may change your vote at any time before the vote at the meeting. If you are a stockholder of record, you may revoke your proxy and change your vote at any time before the annual meeting by (i) submitting to our corporate secretary at our corporate offices a notice of revocation or a duly executed proxy bearing a later date (or by subsequently voting via the Internet) by the deadline noted above or (ii) virtually attending the annual meeting and voting online during the annual meeting. Participation in the meeting will not itself revoke a previously granted proxy.

If you hold your shares in street name, you may change your vote any time before the annual meeting by submitting new voting instructions to your bank, broker, or other holder of record by following the instructions they provided.

What To Do If You Received More Than One Notice

This means that your shares are registered differently and are held in more than one account. To ensure that all shares are voted, please either vote each account over the internet, or sign and return by mail all proxy cards. We encourage you to register all of your shares in the same name and address by contacting the Shareholder Services Department at our transfer agent, Equiniti Trust Company, LLC, at (800) 937-5449. If you hold your shares through an account with a bank or broker, you should contact your bank or broker and request consolidation of your accounts.

Meeting Admission

All stockholders as of the record date, or their duly appointed proxies, may attend the virtual meeting. Please note that if you hold shares in street name, you will need to have a copy of a brokerage statement to present to the operator reflecting your stock ownership as of the record date.

Meeting Quorum

The presence in person or by proxy at the meeting of the holders of a majority of all outstanding shares of common stock entitled to vote at the meeting on the record date will constitute a quorum, permitting the conduct of business at the meeting. As of the record date, 103,843,183 shares of our common stock were outstanding and entitled to vote at the meeting. Abstentions and broker non-votes will be included in the calculation of the number of shares considered to be present at the meeting.

If less than a majority of the outstanding shares of common stock entitled to vote are represented at the meeting, a majority of the shares present at the meeting may adjourn the meeting to another date, time, or place, and notice need not be given of the new date, time, or place if the new date, time, or place is announced at the meeting before an adjournment is taken.

Required Vote

Proposal One — Election of Directors. Each nominee who receives a majority of the votes cast with respect to such director, which means more votes cast “FOR” such nominee than votes cast “AGAINST” such nominee, from the shares represented at the annual meeting and entitled to vote therefor will be elected as a class II director. Stockholders do not have the right to cumulate their votes for directors.

Proposal Two — Approval of the TTM Technologies, Inc. Equity Advantage Match Plan. The affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the meeting and entitled to vote will be required for approval of the TTM Technologies, Inc. Equity Advantage Match Plan.

Proposal Three — Advisory, Non-Binding Vote to Approve Named Executive Officer Compensation. The affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the meeting and entitled to vote will be required for approval of the advisory, non-binding vote on the compensation of the Company's named executive officers. Because this vote is advisory, it will not be binding upon our Board of Directors. However, the Human Capital and Compensation Committee and our Board of Directors will take into account the outcome of the vote when considering future executive compensation arrangements.

Proposal Four — Advisory Non-Binding Vote on the Frequency of Future Advisory, Non-Binding Votes to Approve Named Executive Officer Compensation. The option of one year, two years or three years that receives a majority of the votes cast will be deemed to be the frequency preferred by the stockholders for future advisory, non-binding votes to approve the compensation of the Company's named executive officers. If none of the frequency alternatives (one year, two years, or three years) receives a majority vote, we will consider the frequency that receives the highest number of votes by stockholders to be the frequency that has been selected by stockholders, on an advisory basis.

Because this vote is advisory, it will not be binding upon the Company or our Board of Directors. However, the Board of Directors will take into account the outcome of the vote when considering the frequency of future advisory, non-binding votes to approve the compensation of our named executive officers. While the Board of Directors is making a recommendation with respect to this proposal, stockholders are being asked to vote on the choices of one year, two years or three years specified above, and not whether they agree or disagree with the Board’s recommendation.

Proposal Five — Ratification of the Appointment of Independent Registered Public Accounting Firm. The affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the meeting and entitled to vote will be required to ratify the appointment of KPMG LLP as the Company's independent registered public accounting firm for the fiscal year ending December 28, 2026.

Other Matters. For each other matter, the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the meeting and entitled to vote on such matter will be required for approval.

If you are a beneficial owner of shares held in "street name" and you do not provide your broker or other nominee with instructions on how to vote your street name shares, your broker or nominee will not be permitted to vote them on “non-routine” matters (and, therefore, there may be broker non-votes on such matters).

Proposals One, Two, Three, and Four are considered non-routine matters under applicable rules. Please note that brokers may not vote your shares on these proposals in the absence of your specific instructions as to how to vote. We encourage you to provide instructions to your broker regarding the voting of your shares.

Broker non-votes will have no effect on the outcome of Proposals One, Two, Three and Four.

The ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 28, 2026 (Proposal Five) is considered a routine matter under applicable rules. A broker or other nominee may generally vote on routine matters, and therefore no broker non-votes are expected to exist in connection with Proposal Five.

Abstentions will have no effect on Proposals One and Four. Abstentions will be treated as being present and entitled to vote on Proposals Two, Three and Five and therefore will have the effect of votes against such Proposals.

Cost of Proxy Solicitation

We will bear the expense of soliciting proxies, including the expense of preparing, printing and mailing this proxy statement and the proxies we solicit. In addition to the use of mail, our employees may solicit proxies personally, by e-mail, facsimile, and by telephone. We do not intend to retain a proxy solicitor in connection with the annual meeting. Our employees will receive no compensation for soliciting proxies other than their regular salaries. We may request banks, brokers, and other custodians, nominees, and fiduciaries to forward copies of the proxy materials to the beneficial owners of our common stock and to request authority for the execution of proxies, and we may reimburse such persons for their expenses incurred in connection with these activities.

Our principal executive offices are located at 200 East Sandpointe, Suite 400, Santa Ana, California 92707, and our telephone number is (714) 327-3000. A list of stockholders entitled to vote at the annual meeting will be available at our offices for a period of 10 days prior to the meeting and at the meeting itself for examination by any stockholder.

PROPOSAL ONE – ELECTION OF DIRECTORS

Directors and Nominees

Our Board of Directors is currently comprised of nine directors. Our Board of Directors is divided into three classes with each class of directors serving for a three-year term or until successors of directors serving in that class have been elected and qualified. Each director elected at the 2026 annual meeting will serve for a term expiring at the 2029 annual meeting or until a successor has been duly elected and qualified. At this annual meeting, our stockholders will be asked to elect three class II directors.

Our Board of Directors has nominated Julie S. England, Philip G. Franklin and Dr. Edwin Roks as class II directors. Ms. England, Mr. Franklin and Dr. Roks currently serve as class II directors. Ms. England, Mr. Franklin and Dr. Roks will stand for re-election at the 2026 annual meeting.

Rex D. Geveden and Pamela B. Jackson serve as class III directors and their terms will expire at the annual meeting of stockholders in 2027. Wajid Ali and Chantel E. Lenard serve as class I directors and their terms will expire at the annual meeting of stockholders in 2028.

As previously disclosed, Thomas T. Edman, who currently serves as a class I director, notified our Board of Directors on January 29, 2026 of his decision to retire from our Board of Directors and any committees thereof, effective as of May 7, 2026 (the “Effective Date”), immediately following the 2026 annual meeting.

As also previously disclosed, pursuant to our Corporate Governance Guidelines, John G. Mayer, who currently serves as a class III director, must submit his resignation and retire from our Board of Directors at the 2026 annual meeting. Because Mr. Mayer will have attained the mandatory retirement age of 75, our Board of Directors may no longer defer and is obligated to accept his resignation.

The Board thanks Mr. Edman and Mr. Mayer for their service and many contributions to TTM.

As previously disclosed, the Board of Directors on January 29, 2026 appointed Daniel G. Korte and Ryan D. McCarthy to fill the class I vacancy and class III vacancy, respectively, that will be created by Mr. Edman’s impending retirement and Mr. Mayer’s impending mandatory retirement, respectively. Mr. Korte’s and Mr. McCarthy's appointments will each be effective as of the Effective Date, with terms expiring at the annual meeting of stockholders in 2028 and the annual meeting of stockholders in 2027, respectively, or at the time of their earlier resignation, retirement or removal.

As a natural mechanism to ensure continuity of our Board of Directors, to satisfy our obligations under the Special Board Resolution (the "SBR”) adopted by the Board and as required by the United States Defense Counterintelligence and Security Agency (the “DCSA”), TTM has continued the practice of providing for staggered elections of three classes of board members to serve three-year terms. During the period that the SBR is in force, our bylaws require that that (i) our Board be composed entirely of U.S. Citizens, (ii) at least three such members maintain a Personnel Security Clearance at least to the level of the Contractor's Facility Security Clearance or would be eligible to be cleared by the United States Government to receive classified information and maintain oversight of TTM’s classified operations (and may not be affiliated with any person or foreign entity of concern to the DCSA), and (iii) our Board be chaired by a member with a Personnel Security Clearance at least to the level of the Contractor's Facility Security Clearance. In addition, per the terms of the SBR, no non-U.S. citizen is allowed to sit on TTM's Board in the future.

TTM is a significant supplier of electronic assemblies, radar and microelectronic systems and printed circuit boards that are eventually integrated into products purchased by the United States Department of War ("DoW") As such, over 400 TTM employees and Board members are cleared by the United States Government to receive confidential or secret classified information. Because TTM has been identified by the government of the United States as a key supplier in the electronics eco-system, TTM has engaged DCSA for approval of facility security clearances at a number of its facilities. This clearance allows the DCSA to conduct audits and provide broad oversight to parts of TTM’s operation. As a condition of such clearance, and in connection with our engagement with the DCSA, in February of 2023, our Board of Directors adopted the SBR, replacing the Special

Security Agreement (“SSA”) that the Company had entered into with the DCSA in 2010. The replacement of the SSA with the SBR was the result of the significantly reduced foreign ownership of TTM. As agreed between the Company and the DCSA, the Company plans to maintain much of the robust infrastructure developed during the adoption of and compliance with the SSA. The SBR codifies, and our bylaws require (during the period that the SBR is in effect), the standing Government Security Committee of TTM’s Board of Directors, consisting of at least 3 Board members that hold a National Security Clearance. In addition, the SBR dictates that TTM will maintain its policies and procedures that have been established pursuant to the provisions of the SSA to mitigate risks to TTM’s operations that serve the national security of the United States, including the maintenance of its cybersecurity plan that meets the requirements of NIST 800-171. DCSA will continue to review TTM’s compliance with the terms of the SBR annually at each of TTM’s sites which operate under a U.S. DoW security clearance.

Our Board of Directors has no reason to believe that any of its nominees standing for election will refuse or be unable to accept election. However, if any nominee is unable to accept election or if any other unforeseen contingencies should arise, our Board of Directors may designate a substitute nominee. If our Board of Directors designates a substitute nominee, the persons named as proxies will vote for the substitute nominee designated by our Board of Directors.

Our Board of Directors recommends a vote “FOR” the nominees for Class II directors.

Information Relating to Corporate Governance and the Board of Directors

Our Board of Directors has determined, after considering all the relevant facts and circumstances, that Messrs. Ali, Franklin, Geveden and Mayer (whose term of office will conclude at the 2026 annual meeting), and Mses. Jackson, England and Lenard are independent directors, as “independence” is defined by the listing standards of the NASDAQ Stock Market (referred to as NASDAQ) and by the SEC. Accordingly, a majority of the members of our Board of Directors are independent. Dr. Roks is not considered to be an independent director as a result of his current position as an executive officer of our Company. Mr. Edman (whose term of office will conclude at the 2026 annual meeting) is not considered to be an independent director as a result of his former position as an executive officer of our Company until September 2025.

Our bylaws authorize our Board of Directors to appoint its members to one or more committees, each consisting of one or more directors. Our Board of Directors has established four standing committees: an audit committee, a human capital and compensation committee, a nominating and corporate governance committee and a government security committee. Our bylaws specifically require that our Board of Directors maintain the government security committee during the period that SBR is in effect. Each of our committees, with the exception of the government security committee (of which Mr. Edman is a member until his term of office concludes at the 2026 annual meeting) is comprised entirely of independent directors, as “independence” is defined by the listing standards of NASDAQ and by the SEC. The Chair of our Board of Directors offers to hold executive sessions following most board meetings at which the independent directors are able to meet without the presence or participation of management.

Our Board of Directors has adopted charters for the audit, compensation, and nominating and corporate governance committees describing the authority and responsibilities delegated to each committee by the Board of Directors. Our Board of Directors has also adopted Corporate Governance Guidelines, a Whistle Blower Policy, a Code of Business Conduct for all employees and a supplemental Code of Ethics for our Chief Executive Officer and senior financial officers.

We post on our website, at https://investors.ttm.com/corporate-governance, the charters of our audit, human capital and compensation, and nominating and corporate governance committees; our Corporate Governance Guidelines; our Whistle Blower Policy; our Code of Business Conduct ("Code of Conduct") for all employees, our Code of Ethics for our Chief Executive Officer and senior financial officers, and any amendments or waivers thereto. These documents are also available in print to any stockholder requesting a copy in writing from our corporate secretary at 200 East Sandpointe, Suite 400, Santa Ana, California 92707.

Interested parties may communicate with our Board of Directors or specific members of our Board of Directors, including the members of our various board committees, by submitting a letter addressed to the Board of Directors of TTM Technologies, Inc., c/o any specified individual director or directors, at 200 East Sandpointe, Suite 400, Santa Ana, California 92707. We will forward any such letters to the indicated directors.

We are committed to conducting our business in an ethical manner in every culture and geography that we operate. Our corporate values emphasize integrity, clear communication, teamwork and performance excellence throughout our employee base. Our Board of Directors ultimately oversees our ESG compliance and initiatives through regular engagement with our senior management team. Our lasting commitment to Corporate Social Responsibility (“CSR”) goes beyond regulatory compliance and is an integral part of our corporate culture and our way of doing business. We are committed to making our workforce inclusive, our business sustainable and friendly to the environment and our stakeholders engaged by maintaining strong environmental, social and governance practices.

TTM Sustainability

As a global organization, TTM recognizes our opportunity to positively impact the world around us by managing our operations in a sustainable manner. We believe that sustainable practices are essential to the long-term success of our business and that we have a responsibility to consider how our business interacts with society, impacts the environment, and can affect the global economy. TTM expects our employees, suppliers, and business partners to use this Corporate Sustainability Policy as guiding principle in their respective roles.

TTM’s Leadership and employees are committed to:

Environmental:

Social:

Governance:

Commitment to Values and Ethics. TTM's corporate culture forms the foundation for the Company. Our culture is driven by personal integrity and performance excellence and we demonstrate the importance we place on these values through our goal setting and performance management process as well as providing ethics training to employees every year. We strive to act in accordance with, and provide annual training for, our Code of Conduct, which outlines our expectations and provides conduct guidance for all employees. Our Code of Conduct includes topics such as anti-corruption, avoidance of discrimination, harassment avoidance, privacy requirements, the appropriate use of company assets, the necessity of protecting confidential information, and the process for reporting suspected Code of Conduct violations. Our Code of Conduct reinforces the importance of fostering an open, welcoming environment in which all employees have a voice and lays out the confidential outlets we have established to raise concerns regarding potential violations.

In addition, the Company maintains high standards for all employees worldwide which include reasonable work hours and time off, no child labor, no forced labor, equal opportunity employment, and a professional work environment that does not tolerate any form of harassment or discrimination. The Company and its employees strive to achieve and maintain a positive and inclusive work environment. In addition, the Company emphasizes health and wellness programs targeted to educate employees on healthy lifestyles and promote fitness plans. We review employee turnover rates paying particular attention to new hires, supervisor and technical staff retention. We believe the emphasis we place on selecting and training new hires as well as coaching supervisors positively impacts our work environment and overall culture. Through internal surveys, it is clear our employees value their relationships with their supervisors, their career opportunities and the corporate culture in general.

Management Policies and Communication. How we manage and leverage our human capital is essential in executing our strategy. At TTM, we believe that a key differentiator is our culture, which has been shaped through considerable thought and energy. Our culture has served us well as we integrate acquired companies and optimize our organizational structures and teams to better serve our customers. The following elements underpin our culture:

Cybersecurity

In order to protect the data of our Company, business partners, U.S. national security, and defense-related items, TTM has invested in robust data security and privacy protections. TTM follows industry-standard recommendations for data security as outlined in the NIST SP 800-171 specification. TTM has been formally certified as Cybersecurity Maturity Model Certification (CMMC) Level 2 compliant by a Certified Third-Party Assessor Organization. TTM has developed detailed cybersecurity policies and procedures, including a data classification system to ensure the protection of critical data. In addition to periodic internal review, TTM also employs external auditors and cybersecurity testing firms to review our cybersecurity posture. The Board of Directors and the Board's Government Security Committee review cybersecurity risk with TTM's Senior Vice President of Information Technology on a regular basis and assesses the cybersecurity risks that TTM faces while providing oversight of TTM’s cybersecurity protective systems, policies and procedures. TTM maintains a CIRT, or Cybersecurity Incident Response Team, and conducts periodic tests with this team to maintain readiness and resiliency, while regularly reviewing its policies in the interest of protecting data security. The regular training of employees, at least twice annually, on cyber threats helps TTM to maintain data security.

Corporate Governance

A key component of our success is a strong foundation of Corporate Governance practices and policies that promote transparency, accountability and engagement exemplified by our Board of Directors. We maintain our Corporate Governance Guidelines to provide direction to our Board of Directors and Senior Management on topics such as board member qualifications, the evaluation process for the CEO and board members and reporting conflicts of interest. In addition to these Guidelines and the strong governance practices that we employ that are described throughout this Proxy Statement, TTM also maintains a Code of Ethics for the CEO and Senior Financial Officers. Further, each committee of the Board of Directors has a charter. All of these documents are available on TTM’s website at https://investors.ttm.com/corporate-governance.

Meetings of the Board of Directors

Our Board of Directors held seven meetings (regular and special) during 2025. All of our directors attended more than 75% of the aggregate of (i) the total number of meetings of the Board of Directors held during 2025, and (ii) the total number of meetings held by all committees of our Board of Directors on which such person served during 2025. We have adopted a policy encouraging each of our directors to attend each annual meeting of stockholders and, to the extent reasonably practicable, we schedule our annual meeting of stockholders during the week of a meeting of the Board of Directors. Eight of our nine current directors attended the 2025 annual meeting of stockholders. Dr. Roks did not attend the 2025 annual meeting of stockholders because he was not appointed to our Board of Directors until after such annual stockholders' meeting.

Committees of the Board of Directors

As of the date of this Proxy Statement, the members and nominees of our Board of Directors and the committees of our Board of Directors on which they serve, are identified below:

* As previously disclosed, Mr. Edman will retire from the Board of Directors and his term of office will conclude at the 2026 annual meeting.

** Mr. Korte’s, Mr. McCarthy’s and Dr. Roks's Board committee assignments will be determined at a later date. Because Dr. Roks is not an independent director as a result of his current position as an executive officer of our company, he is eligible to serve only on the Board's Government Security Committee.

*** Pursuant to our Corporate Governance Guidelines and as previously disclosed, Mr. Mayer will retire from the Board of Directors and his term of office will conclude at the 2026 annual meeting.

Audit Committee. Our Audit Committee provides assistance to the Company’s Board of Directors in fulfilling its responsibility to stockholders, the investment community and governmental agencies that regulate the activities of the Company with respect to oversight of: (i) the integrity of the Company’s accounting and financial reporting process, financial statements and financial statement audits; (ii) the Company’s compliance with legal and regulatory requirements; (iii) the independent auditor’s qualifications, independence and performance; (iv) the performance of the Company’s internal audit function; and (v) the performance of the Company’s internal accounting controls, disclosure controls and procedures, and internal control over financial reporting. Our audit committee actively consults with our management and our independent registered public accounting firm regarding the preparation of financial statements and, as appropriate, initiates inquiries into aspects of our financial affairs. In addition, our audit committee has the responsibility to consider and recommend the appointment of, and to pre-approve services provided by, and fee arrangements with, our independent registered public accounting firm. The current members of our audit committee are Messrs. Franklin (chair), Ali, Mayer (whose term of office will conclude at the 2026 annual meeting) and Ms. Jackson, each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The Board of Directors has determined that Mr. Franklin is “financially sophisticated” under NASDAQ rules and qualifies as an “audit committee financial expert” in accordance with applicable rules and regulations of the SEC. Our audit committee held four meetings during 2025.

Our audit committee has a written charter that delineates its responsibilities, a full copy of which is posted on our website at https://investors.ttm.com/corporate-governance.

Human Capital and Compensation Committee. Our human capital and compensation committee conducts a general review of our employee compensation and benefit plans to ensure that they meet our corporate objectives. The human capital and compensation committee reviews and determines, or recommends to our Board of Directors, the compensation of our Chief Executive Officer and all other individuals

designated by our Board of Directors as executive officers of our Company. In addition, our human capital and compensation committee reviews and approves our corporate goals and objectives relevant to the compensation for our Chief Executive Officer and other executive officers, including annual performance objectives, and evaluates the performance of our Chief Executive Officer and other executive officers in light of these goals and objectives. The human capital and compensation committee reviews and makes recommendations to our Board of Directors with respect to compensation and “people” related matters and monitors talent and career development and retention of our employees. In addition, the human capital and compensation committee approves our incentive compensation plans and equity-based plans, and activities relating to those plans. The human capital and compensation committee also establishes and periodically reviews policies in the area of perquisites for executive officers. The human capital and compensation committee may, delegate any or all of its responsibilities to a subcommittee.

In discharging its responsibilities, our human capital and compensation committee is empowered to investigate any matter of concern that it deems appropriate and has the sole authority, without seeking approval from the entire Board of Directors, to retain outside consultants for this purpose, including the authority to approve any terms of retention. Our human capital and compensation committee retained Exequity, FW Cook and Aon/Radford as our compensation consultants for 2025 to provide an independent review of various aspects of the Company’s board and executive compensation programs, including an analysis of the competitive market. Our human capital and compensation committee assessed the independence of Exequity, FW Cook and Aon/Radford pursuant to SEC and NASDAQ rules and concluded that each of Exequity, FW Cook and Aon/Radford is independent and that their work has not raised any conflict of interest. Additional information regarding the role of compensation consultants and executive officers in assisting our human capital and compensation committee in determining the amount or form of executive compensation may be found in “Compensation Discussion and Analysis” below. The current members of our human capital and compensation committee are Mses. Lenard (chair), England and Jackson, each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The human capital and compensation committee held five meetings during 2025.

Our human capital and compensation committee has a written charter that delineates its responsibilities, a full copy of which is posted on our website at https://investors.ttm.com/corporate-governance.

Nominating and Corporate Governance Committee. The nominating and corporate governance committee oversees the selection and composition of our Board of Directors and oversees the management of our continuity planning processes. It establishes, monitors, and recommends the purpose, structure, and operations of the various committees of our Board of Directors, the criteria and qualifications for membership of each board committee, and recommends whether rotations or term limits are appropriate for the chair or committee members of the various committees. In addition, the nominating and corporate governance committee recommends individuals to stand for election as directors and recommends directors to serve on each committee as a member or as chair of the committee. The nominating and corporate governance committee reviews director compensation and recommends changes in director compensation to our Board of Directors with the support of our compensation consultant. The nominating and corporate governance committee reviews and makes recommendations regarding our governing documents (including our certificate of incorporation and bylaws) and our environmental, social and corporate governance principles, policies and practices. The nominating and corporate governance committee is also responsible for considering policies relating to the meetings of our Board of Directors and considers questions of independence and possible conflicts of interest of members of our Board of Directors and executive officers. Finally, the nominating and corporate governance committee oversees the performance evaluation for our Board of Directors and management.

The nominating and corporate governance committee will consider persons recommended by stockholders for inclusion as nominees for election to our Board of Directors if the information required by our current bylaws is submitted in writing in a timely manner and addressed and delivered to our Company’s secretary at 200 East Sandpointe, Suite 400, Santa Ana, California 92707. Under our current bylaws, a

stockholder who intends to recommend a nominee to our Board of Directors must provide (a) all information relating to the individual subject to the nomination that is required to be disclosed in opposition proxy statements for election of directors filed by stockholders, at their own expense, in a contested election, or as otherwise required under Regulation 14A under the Securities Exchange Act of 1934, as amended (referred to as the Exchange Act), (b) a description of all relationships, including, but not limited to, any agreements or understandings between the proposed nominee and the stockholder giving the notice, (c) a representation and agreement from the proposed nominee that (A) he or she is not, and will not become, a party to any arrangement or understanding not disclosed to the Company with any person or entity with respect to (I) how the proposed nominee, if elected as a director, will vote on any issue or question or (II) any direct or indirect compensation, reimbursement, or indemnification in connection with his or her service or action as a director, and (B) if elected as a director, he or she will comply with all applicable corporate governance, conflict of interest, confidentiality, stock ownership and trading and other policies and guidelines of the Company applicable to all directors and in effect during such person’s time in office as a director, (d) a fully completed and executed director questionnaire in the form required by the Company, and (e) the individual’s written consent to being named in a proxy statement as a nominee and to serving as a director if elected. The questionnaire is available from our secretary upon written request and upon the requesting person’s providing certain written representations required by our current bylaws. The stockholder making the nomination must also provide the information required by our current bylaws relating to such stockholder, and any beneficial owner on whose behalf the nomination is being made, including information pertaining to ownership of our capital stock, must make certain representations relating to voting intent and delivery of proxies and must provide any other information related to the stockholder or beneficial owner that would be required to be disclosed in a proxy statement or other filings required to be made in connection with the solicitation of proxies for the election of directors in a contested election under Regulation 14A of the Exchange Act. In addition, to comply with the universal proxy rules, our bylaws also provide that stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act and must also comply with all other requirements of Rule 14a-19 under the Exchange Act.

The nominating and corporate governance committee identifies and evaluates nominees for our Board of Directors, including nominees recommended by stockholders, based on numerous factors it considers appropriate, some of which may include strength of character, mature judgment, career specialization, relevant technical skills, and the extent to which the nominee would fill a present need on our Board of Directors. The nominating and corporate governance committee evaluates nominees for director in the same manner, regardless of whether the nominee is recommended by a stockholder or other person or entity. At least annually, the nominating and corporate governance committee evaluates the skills and experience of its current members of the Board of Directors which help inform the Board of the attributes and experience it may seek in

the potential selection of future members of the Board. The skills matrix used by the nominating and corporate governance committee is set forth below.

In evaluating Director candidates, our nominating and corporate governance committee bears in mind that the foremost responsibility of a director is to represent the interests of our stockholders as a whole. Directors are expected to exemplify the highest standards of personal and professional integrity and to constructively challenge management through their active participation and questioning. In consideration of these expectations, the nominating and corporate governance committee seeks directors with established strong professional reputations and expertise in areas relevant to the strategy and operations of our business. The activities and associations of candidates are reviewed for any legal impediment, conflict of interest, or other consideration that might prevent service on our Board of Directors.

When considering potential director nominees, the charter of the nominating and corporate governance committee provides that the committee shall take into account all factors it considers appropriate which may include strength of character, mature judgment, career specialization, relevant technical skills, diversity and the extent to which the candidate would fill a present need on the Board of Directors.

The current members of our nominating and corporate governance committee are Ms. England (chair) and Messrs. Ali, Geveden and Mayer (whose term of office will conclude at the 2026 annual meeting), each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The nominating and corporate governance committee held four meetings during 2025.

Our nominating and corporate governance committee has a written charter that delineates its responsibilities, a full copy of which is posted on our website at https://investors.ttm.com/corporate-governance.

Government Security Committee. As previously disclosed in our filings with the SEC, a portion of our business consists of manufacturing defense and defense-related items for various departments and agencies of the U.S. government, including the U.S. DoW, which requires that we maintain facility security clearances under the National Industrial Security Program (“NISP”). The NISP requires that a corporation maintaining a facility security clearance take steps to mitigate foreign ownership, control, or influence (referred to as FOCI). On February 1, 2023, our Board of Directors passed a Special Board Resolution (“SBR”), replacing the Special Security Agreement (“SSA”) that we entered into in with the Defense Counterintelligence and Security Agency (“DCSA”) in 2010. The replacement of the SSA with the SBR is a result of the significantly reduced foreign

ownership of TTM. DCSA acknowledged the SBR and terminated the SSA on April 25, 2023. The SBR codifies and our bylaws require (during the period that the SBR is in effect), the maintenance of the Government Security Committee of the Board to oversee our compliance and cybersecurity efforts and to put into place best practices in our facilities in the U.S. and overseas to insure that we maintain robust security practices and policies as we serve the interests of our customers in the Aerospace and Defense market. Our Government Security Committee, consists of at least 3 Board members that hold a Personal Security Clearance, as required by our bylaws. The DCSA will continue to review TTM’s compliance with the terms of the SBR annually at each of TTM’s sites which operate under a U.S. DoW security clearance. In addition, all of TTM’s Board is currently comprised of U.S. citizens and per the terms of the SBR, in the future, no non-U.S. citizen will be allowed to sit on TTM’s Board. The current members of our Government Security Committee are Messrs. Geveden (chair) and Edman (whose term of office will conclude at the 2026 annual meeting,) and Ms. England. Our Government Security Committee held four meetings during 2025.

Board Leadership Structure. We believe it is our Chief Executive Officer’s responsibility to manage our Company’s operations and the Chair’s responsibility to lead our Board of Directors. Given the significant responsibilities with which our Chair is tasked and his active role in our governance, we believe it is beneficial to have an independent chair who is dedicated to leading the Board of Directors for the Company. To this end, our Corporate Governance Guidelines provide that our Chief Executive Officer may not be our Chair, and that our Chair will be selected from our independent directors. In making its decision to separate the Chief Executive Officer and Chair roles, our Board of Directors considered the time that Dr. Roks is required to devote to the Chief Executive Officer position, particularly given the demands imposed on our global Company. By segregating the role of the Chair, we reduce any duplication of effort between the Chief Executive Officer and the Chair. We believe this provides strong leadership for our Board of Directors, while also positioning our Chief Executive Officer as the leader of the Company in the eyes of our customers, employees, and other stakeholders.

Our Board of Directors currently has seven independent members and two non-independent members, specifically Dr. Roks, our President and Chief Executive Officer, and Mr. Edman, our former President and Chief Executive Officer (whose term of office will conclude immediately following the 2026 annual meeting). The Board of Directors has determined that Mr. Korte and Mr. McCarthy, who have been appointed to serve on the Board of Directors effective as of May 7, 2026, will each be an independent director. A number of our independent board members are currently serving or have served as members of senior management of other public companies or governmental agencies and have served as directors of other public companies. We believe that the number of independent, experienced directors that make up our board, along with the independent oversight of the Board of Directors by a non-executive chair, benefits our Company and our stockholders.

Both our bylaws and the SBR, as required by the DCSA, establishes certain criteria for the qualifications of our directors and the composition of our Board of Directors, and also requires that a certain number of directors maintain Personnel Security Clearances and that all Directors be U.S. citizens. Our current Board of Directors meets the composition criteria and our board has determined to maintain certain cleared members of the Board of Directors in part because of these critical requirements set by the government of the United States.

We believe that we have a strong corporate governance structure that ensures independent discussion among, evaluation of, and communication with and access to, senior management. With the exception of our Government Security Committee, of which Mr. Edman is a member, until his term of office concludes at the 2026 annual meeting, all of our board committees are composed solely of independent directors, which provide independent oversight of management. Also, our Corporate Governance Guidelines provide that our independent directors will have the opportunity to meet in executive session not less frequently than quarterly.

Risk Management and Oversight Process. While our management is primarily responsible for managing risk, our Board of Directors and each of its committees play a role in overseeing our risk management practices. Our full Board of Directors is ultimately responsible for risk oversight, and it discharges this responsibility by, among other things, receiving regular reports from our management, including an annual enterprise risk assessment conducted by our internal audit function based on the feedback received from our internal leadership team, concerning our business and the material risks that our Company faces. Our Board of Directors annually reviews key enterprise risks identified by management, such as financial, reputational, safety and security, cybersecurity, operational, revenue, social responsibility, environmental and compliance risks, and it monitors key risks through reports and discussions regarding key risk areas at meetings of our Board of Directors

and in committee meetings. Our Board of Directors also focuses on specific strategic and emerging risks in periodic strategy reviews. Our Board of Directors annually reviews and approves our corporate strategy and goals and our capital budgets, and in connection with that review, it considers risks associated with our Company.

Our Board of Directors allocates responsibility for overseeing risk management for our Company among the full board and each of its committees. Specifically, the full board oversees significant risks primarily relating to operations, strategy, finance, cybersecurity, environmental, health and safety matters, liability insurance programs, and compliance with environmental legal and regulatory and social responsibility requirements. In addition, each of our committees considers risks within its area of responsibilities, as follows:

Through the activities of our audit, compensation, nominating and corporate governance, and government security committees, as well as the full Board of Directors’ interactions with management concerning our business and the material risks that may impact our Company, the Board of Directors and each respective committee is able to monitor our risk management process and offer critical insights to our management.

We have adopted an Insider Trading Policy governing the purchase, sale, and/or other dispositions of our securities by directors, officers, and employees, which is reasonably designed to promote compliance with insider trading laws, rules and regulations, and applicable NASDAQ listing standards. Our Insider Trading Policy, a copy of which is filed as an Exhibit 19 to our Annual Report on Form 10-K, prohibits our employees from engaging in certain transactions involving TTM’s securities, including but not limited to the use of financial instruments such as puts, calls, derivatives, zero-cost collars, and forward sales contracts, short sales, pledging TTM securities as collateral for a loan, or subject to margin call or other involuntary sales, or otherwise engage in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities. Our officers and directors are also further prohibited from engaging in these types of hedging transactions. See “Director Compensation – Stock Ownership, Hedging and Pledging Policies” and “Compensation Discussion and Analysis – Compensation Overview – Alignment of Compensation and Performance – Compensation Practices.”

Related Person Transaction Policies and Procedures. It is the responsibility of our full Board of Directors and our audit committee to review and approve related party transactions. It is our management’s responsibility to bring such related party transactions to the attention of our Board of Directors and members of our audit committee. From time to time, our nominating and corporate governance committee, in accordance with its charter, will also review potential conflict of interest transactions involving members of our Board of Directors and our executive officers. In accordance with our Corporate Governance Guidelines, any monetary engagement (other than director or employee compensation or transactions which would not require disclosure under Item 404 of Regulation S-K) (a) between a director (including any entity of which the director is a director or executive officer and any member of a director’s family as defined in NASDAQ rules) and our Company or any of its affiliates or members of senior management or their families, and (b) between executive officers of our Company (as designated by our Board of Directors) and our Company or any of its affiliates, is subject to the approval of our audit committee or our independent directors. Each of our directors and executive officers must notify our Board of Directors in advance of entering into any such transaction.

Our Corporate Governance Guidelines task our Board of Directors, in consultation with our nominating and corporate governance committee, with reviewing annually the relationships that each director has with us, directly or indirectly. Further, our nominating and corporate governance committee is tasked with periodically reviewing the compensation arrangements and other business relationships between our directors and our Company in order to monitor the independence of our directors. Our Corporate Governance Guidelines also provide that if an actual or potential conflict of interest develops, a director should report the matter immediately to the full Board of Directors and our audit committee for evaluation and appropriate resolution. If a director has a personal interest in a matter before our Board of Directors, the director must disclose the interest to the full Board of Directors and our audit committee, must recuse themselves from participation in the related discussion, and must abstain from voting on the matter.

Stock Ownership Guidelines, and Hedging and Pledging Policies. Our Board of Directors recognizes that stock ownership by directors may strengthen their commitment to the long-term future of our Company and further align their interests with those of our stockholders. Within a five (5) year period after becoming a member of the Board of Directors, each member of the Board of Directors is required to beneficially own shares of our common stock (including shares owned outright, unvested shares, and restricted stock units), having a value of at least five times their annual cash retainer, and as our directors are subject to our insider trading policy, they are prohibited from pledging or hedging their shares. As of the date of this Proxy Statement, all of our current outside Board members meet the stock ownership guidelines as of the Record Date. In addition, the Company has adopted stock ownership guidelines for the Chief Executive Officer and his direct reports. For a full description of such guidelines, see page 44.

DIRECTOR COMPENSATION

Our non-employee directors receive the following cash compensation on an annual basis: a cash retainer that averages $82,500 annually among the non-employee directors, an annual cash retainer of $9,000 for each

board committee of which such director is a member (except for the government security committee), and reimbursement of expenses relating to attendance at board and board committee meetings. In addition, the Chair of the Board receives an annual cash retainer of an additional $70,000, and the chairs of our various board committees receive annual cash retainers as follows: $25,000 to our audit committee chair, an average of $18,500 annually to our human capital and compensation committee chair, $15,000 to our government security committee chair, and an average of $18,500 annually to our nominating and corporate governance committee chair. Annually, our nominating and corporate governance committee, in consultation with our compensation consultant, reviews our board compensation against the board compensation of our peer companies to develop a reasonable board compensation package.

In addition, our non-employee directors are granted the following equity compensation on an annual basis: the Chair of the Board receives restricted stock units (“RSUs”) in the amount of $220,000 and each non-employee director receives restricted stock units in the amount of $170,000, and the number of shares granted in each case is based upon the average closing price of our common stock over the six-month period preceding the grant date. In the instance where a Board Member serves a portion of the year, the compensation granted is prorated for the time served that year. The RSUs awarded to the non-employee directors prior to 2026 vest in full on the first anniversary of the grant date; however, in an effort to further align Board Members’ interests with those of our stockholders, our current policy is for delivery of the shares of common stock underlying the RSUs to be deferred until retirement from the Board of Directors (or until one year after retirement in the case of certain prior grants).

Mr. Edman (whose term of office will conclude at the 2026 annual meeting) and Dr. Roks are not compensated for their service as directors. Dr. Roks's compensation as our President and Chief Executive Officer is described below under “Compensation Discussion and Analysis” and “Executive Compensation”.

Nonqualified Deferred Compensation. Our directors are permitted to defer 5% to 100% of annual director fees into our Executive and Director Deferred Compensation Plan. In 2025, none of our directors participated in the Executive and Director Deferred Compensation Plan.

Compensation Consultant and its Affiliates

Exequity was retained in 2024 by our human capital and compensation committee to provide an independent review of the Company’s executive compensation programs, including an analysis of the competitive market for 2025. In September 2025, the committee engaged FW Cook to replace Exequity and continue providing this independent guidance. Prior to the transition, Exequity assisted the human capital and compensation committee with its evaluation of the risks associated with our compensation programs and executive director compensation data services, which FW Cook now provides. During their respective engagement periods, both firms furnished the human capital and compensation committee with reports on peer company practices relating to the following matters: short-term and long-term compensation program design; equity compensation; vesting practices and ownership guidelines; target incentive opportunities; and compensation trends for board management and committee members. During 2025, the human capital and compensation committee also engaged AON Radford for services rendered in connection with the computation of total stockholder return (“TSR”) relative to our TSR Peer Group, and for compensation survey data. Our deferred compensation program continues to be managed by Fidelity.

DELINQUENT SECTION 16(a) REPORTS

Under U.S. securities laws, directors, certain officers and persons holding more than 10% of our common stock must report their initial ownership of our common stock and any changes in their ownership to the SEC. The SEC has designated specific due dates for these reports and we must identify in this Proxy Statement those persons who did not file these reports when due.

Based solely upon our review of the copies of such forms that we received during the fiscal year ended December 29, 2025, and written representations of our directors and officers that no other reports were required, we believe that each person who at any time during such year was a director, officer, or beneficial owner of more than 10% of our common stock complied with all Section 16(a) filing requirements during the fiscal year ended December 29, 2025, except that Steven Spoto filed one Form 4 seven business days late on March 13, 2025 with respect to Mr. Spoto’s sale of shares of our common stock in an open market transaction.

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Discussion and Analysis, or CD&A, describes and analyzes our executive compensation philosophy and program in the context of the compensation paid during the last fiscal year to our named executive officers, or our NEOs. For the fiscal year 2025, our NEOs were:

This CD&A is organized into four sections:

Compensation Overview – Alignment of Compensation and Performance

Our primary goal is to tie our Company Executives' compensation closely with performance. The information below provides an executive summary of our Company’s financial performance for fiscal year 2025 and how pay is aligned with performance.

KEY ACCOMPLISHMENTS IN 2025

TTM’s commitment to its strategy of diversification, differentiation and discipline led to TTM’s continued financial strength in 2025. We generated Non-GAAP net income of $259.0 million in 2025, which profitability was the result of revenue growth, improved operational execution, and prudent cost management. For an explanation of the use of Non-GAAP metrics, a presentation of comparable financial measures calculated and reported in accordance with GAAP, and a reconciliation to those audited GAAP metrics, see Annex A attached hereto.

PERFORMANCE HIGHLIGHTS

The Company achieved excellent financial performance in 2025.

ALIGNMENT OF PAY AND PERFORMANCE

TTM’s executive compensation is strongly aligned to Company performance and measurable financial metrics. The following charts show improvement and continued excellence in metrics that we track related to our financial performance over the past five years, which we believe drove increases in realized officer compensation. (1)

The charts below measure the total compensation realized for the CEO and the average total compensation for our NEOs for the past three years (the amount depicted below is different than the amount shown in the Summary Compensation Table because the actual number of PRUs earned (0% up to the maximum level of 200%) will depend on the Company's future achievement of financial performance goals (80% weighting) and TSR (20% weighting) over a three year performance period).

These charts demonstrate alignment in pay and performance as increases in realized officer compensation followed improving financial and stock price performance. The Company’s performance and the price of the Company’s common stock on the NASDAQ directly impacts total compensation realized by our executives.

2025 SAY ON PAY VOTE

At our 2025 annual meeting, our stockholders overwhelmingly approved, on an advisory basis, the compensation of our NEOs described in our 2025 proxy statement. Approximately 98.21% of the votes cast on the matter were voted “For” such advisory “Say-on-Pay” approval, thereby providing the human capital and compensation committee with verification that its compensation practices align the interests of the Company’s executives with those of the Company’s stockholders.

COMPENSATION PRACTICES

We continually review the Company’s executive compensation program to maintain compensation practices that are in the best interests of our stockholders. Some of our key policies are summarized below:

Executive Compensation Philosophy and Objectives

The objective of the human capital and compensation committee of our Board of Directors is to attract, motivate, and retain executives and reward the creation of stockholder value. We seek to provide executive compensation packages that are competitive with comparable companies and reward the achievement of short-term and long-term performance.

We use a combination of fixed and variable compensation programs to reward and incentivize strong performance, as well as to align the interests of our executives with those of our stockholders. We generally target total compensation around the 50th percentile of comparable companies. We believe that this philosophy will continue to enable us to remain competitive in attracting and retaining qualified executive officers while avoiding paying amounts in excess of what we believe is necessary to attract and retain such executive officers. However, our human capital and compensation committee’s decisions on target compensation for specific individuals are also influenced by a variety of additional factors, including compensation practices of businesses acquired by us, and Company and individual performance.

Each year our human capital and compensation committee, together with our senior management, establishes performance targets for short-term and long-term incentive plans that require the achievement of significant financial results. The committee determines compensation by assessing prior year performance against these established financial targets, as well as other factors such as the compensation paid by comparable companies, achievement of strategic objectives, and the professional development and potential of individual officers. Ultimately, the amount of compensation awarded to our executives is determined based on performance and what our human capital and compensation committee believes is in the best interests of our stockholders.

We believe that our use of restricted stock units and performance-based restricted stock units, together with an annual incentive bonus program that is based on various combinations of global operating income, sector operating income, and global cash flow from operations as a percentage of revenue shows that we have closely linked executive officer pay to performance over multiple time periods to balance both short and long term focus. Our pay mix consists primarily of base salary, annual performance-based cash bonus, performance-based equity incentives and time-based equity incentives. We have no executive retirement plans except our 401(k) plan and deferred compensation plan available to U.S. employees, and the company does not contribute to the deferred compensation plan.

Role of the Human Capital and Compensation Committee

Our human capital and compensation committee, which is currently comprised of three independent members of our Board of Directors, as discussed in greater detail under “Information Relating to Corporate Governance and the Board of Directors,” is responsible for, among other things:

Our human capital and compensation committee, in consultation with the outside executive compensation consultant retained by our human capital and compensation committee, also helps analyze the reasonableness and effectiveness of our overall executive compensation packages.

While our Chief Executive Officer and other executive officers may attend meetings of the human capital and compensation committee or our Board of Directors from time to time, the ultimate decisions regarding executive officer compensation are made solely by the members of our human capital and compensation committee and, in the case of compensation decisions for our Chief Executive Officer, the non-employee members of our Board of Directors. These decisions are based not only on our human capital and compensation committee’s deliberations, but also on input requested from outside advisors, including our outside compensation consultant, with respect to, among other things, market data analyses. The final decisions relating to our Chief Executive Officer’s compensation have historically been based on recommendations of our human capital and compensation committee and included discussions with and approval by all of our non-employee directors without the presence of our Chief Executive Officer or other management. Our human capital and compensation committee always makes final decisions regarding his compensation when he is not present. Decisions regarding other executive officers have typically been made by our human capital and compensation committee after considering recommendations from our Chief Executive Officer.

Our human capital and compensation committee has historically engaged the services of an outside compensation consultant to provide independent advice in connection with making executive compensation determinations. The chair of our human capital and compensation committee, in consultation with other committee members, defines the scope of any consultant’s engagement and related responsibilities. These responsibilities may include, among other things, advising on issues of executive compensation and equity compensation structure and assisting in the preparation of compensation disclosure for inclusion in our SEC filings. In fulfilling its responsibilities, the outside compensation consultant may interact with management or our other outside advisors to the extent necessary or appropriate.

More specifically, the Compensation Consultant evaluated our selected peer companies and provided competitive compensation data and analysis relating to the compensation of our Chief Executive Officer and our other senior officers. The Compensation Consultant also furnished the human capital and compensation committee with reports on peer company practices relating to the following matters: short-term and long-term compensation program design; equity compensation, vesting practices and ownership guidelines; retention value of current equity holdings; target incentive opportunities; and compensation trends for board and committee members. In addition, the Compensation Consultant assisted the human capital and compensation committee with its evaluation of the risks associated with our compensation programs and provided our nominating and corporate governance committee with an assessment of our directors’ compensation.

The Compensation Consultant provides analyses and advice that inform the committee’s decisions, but it does not decide or approve any compensation decisions. The Compensation Consultant reviews various proposals presented to the committee by management and provides updates on market trends and the regulatory environment as it relates to executive compensation. The Compensation Consultant reports directly to our human capital and compensation committee and not to management. Our human capital and compensation committee assessed the independence of the Compensation Consultant pursuant to SEC and NASDAQ rules and concluded that the Compensation Consultant is independent and that the work of the Compensation Consultant has not raised any conflicts of interest.

Compensation Levels and Benchmarking. Overall compensation levels for executive officers are determined based on one or more of the following factors: the individual’s duties and responsibilities within our global Company; the individual’s experience and expertise; the compensation levels for the individual’s peers within our Company; compensation levels for similar positions in the electronics industry or in the technology industry more generally; performance of the individual and our Company as a whole; and the levels of compensation necessary to recruit new executive officers. Our human capital and compensation committee reviewed the compensation of our officers and compared it with that of both our peer group companies and broader, composite global market survey data provided by our Compensation Consultant.

Compensation Peer Groups. To assess our executive compensation relative to the competitive market, the Human Capital and Compensation Committee evaluates the compensation levels and practices of a peer group consisting of companies that are similar in size and business focus and represent the organizations with which we compete for executive talent.

In developing the compensation peer group used to inform pay decisions for 2025, the following general screening criteria were used to identify comparable companies:

The Human Capital and Compensation Committee reviews our compensation peer group annually for continued appropriateness and makes adjustments as necessary. No changes were made to the peer group for 2025.

Our human capital and compensation committee believes that the selected Total Shareholder Return (TSR) Peer Group is more relevant for determining whether TSR under our PRU Program reflected high performance relative to global competitors. For a discussion regarding how the TSR Peer Group affects executive compensation, please see the “Long-Term Equity Awards” section on page 37.

Members of our human resources and finance departments work with our Chief Executive Officer to recommend changes to existing compensation plans and programs, to define financial and other performance goals to be achieved under the incentive programs, and, ultimately, to implement the decisions.

Our Chief Executive Officer is actively engaged in setting compensation for other executives through a variety of means, including recommending for committee approval the financial goals, annual salaries, variable pay, and equity grants for members of the executive team. He works closely with other members of executive management in analyzing relevant market data to determine base salary and annual target bonus opportunities for senior management and to develop targets for our short-term and long-term incentive plans. Our Chief Executive Officer is generally subject to the same financial performance goals as our other executive officers, all of which are ultimately determined and approved by our human capital and compensation committee.

Compensation Structure

Although the final structure may vary from year to year and officer to officer, our human capital and compensation committee utilizes three main components for executive officer compensation: base salary, annual incentive bonus and long-term equity incentives.

In determining the allocation each year the committee considers the following factors: our short-term and long-term business objectives, competitive trends within our industry, and the importance of creating a performance-based environment that ties a significant portion of each executive officer’s compensation to the achievement of performance targets and corporate objectives. When considering a proposed compensation package for an executive officer, our human capital and compensation committee considers the compensation package as a whole, including each element of total compensation. We have no pre-established policy for allocating between either cash and non-cash or short-term and long-term compensation.

Our human capital and compensation committee believes that the particular elements of compensation identified above produce a well-balanced mix of stock-based compensation, retention value, and at-risk compensation that collectively provides each executive officer with both short-term and long-term performance incentives. Base pay provides the executive officer with a measure of security as to the minimum level of compensation while the annual and long-term incentive components motivate the executive officer to focus on the business metrics that will maximize company performance over the long term. Our human capital and compensation committee believes that this approach supports increasing stockholder value, rewards executive officers, and assists with long-term officer employment retention.

Salary, bonus, and long-term incentive compensation are emphasized differently based on employee's position and ability to impact financial results. In general, the amount of performance-based pay at-risk, increases with job responsibility. This is intended to offer an opportunity for gain in the event of successful performance, matched with the prospect of less compensation when performance falls short of established financial and/or stockholder return targets.

Base Salary. Base salaries for our executive officers are determined based on the level of the position within our Company, the individual’s performance in recent periods, and the executive’s potential for continued development within our global organization. The base salary levels, and any changes to those levels for each executive officer, are reviewed and approved each year by our human capital and compensation committee. However, there is no specific weighting applied to any one factor in setting the level of base salary, and the process ultimately relies on the human capital and compensation committee’s judgment. We believe that providing base salaries around the median of our peer group and the broader market survey provided by our Compensation Consultants will enable us to remain competitive for qualified executive officers.

Base Salaries for 2025. Our normal cadence for compensation review takes place on July 1 of each year.

The table below outlines the 2024 and 2025 base salaries for all of our fiscal year 2025 NEOs:

Annual Incentive Bonus Plan. Our human capital and compensation committee believes that annual performance-based cash bonuses play an important role in providing incentives to our executive officers to achieve near-term financial metrics and individual goals. The financial metrics are 90% of each NEO's bonus and individual goals are 10%.

Executive officers are rewarded for company-wide performance in operating income and operating cash flow to support collaboration and overall accountability. Executives responsible for sector performance are also tied to sector performance in addition to Corporate performance to enhance line of sight. The human capital and compensation committee focuses on operating income and operating cash flow for measuring success in a manner that management can easily track and communicate. In addition, individual performance goals ensure that other important areas of our business are measured and emphasized.

In response to the recommendations of management, our human capital and compensation committee based the Company’s incentive bonus plan on several metrics that the committee believed most closely aligned the executive’s incentive pay with metrics that the executive is responsible for managing. For 2025, the below chart reflects the weight of each performance metric.

Each executive officer has a target annual incentive bonus opportunity, expressed as a percentage of base salary, with the ability to earn between zero and 200% of that target bonus based on our Company’s actual performance. The table below lists the 2025 base salaries and bonus levels for each of our current NEOs at the different potential goal achievement outcomes. This table includes both the financial metrics as well as the individual goals.

Annual Incentive Bonus for 2025. In February 2026, our human capital and compensation committee reviewed our 2025 performance relative to the 2025 operating income and cash flow from operations as a percentage of revenue goals. The performance was certified at 149.2% of the global operating income goal and 88.7% of our goal for global cash flow from operations as a percentage of revenue. The human capital and compensation committee also reviewed and assessed the performance achieved against the individual goals that had been established for each of the members of the Company’s executive team, including Messrs. Roks, Edman, Boehle, Soder, Weber, and Ms. Gridley. We use individual performance goals to ensure that other important areas of our business are measured and emphasized, which may include but are not limited to customer satisfaction, market positioning and growth, structural and organizational improvements, and critical projects and assignments. Performance goals do not payout unless our Company achieves its threshold financial performance metrics. As a result, our human capital and compensation committee authorized the payment of 2025 incentive bonuses as follows:

Because such a large percentage of executive officer compensation is performance-based, our human capital and compensation committee invests significant time determining the financial targets for our annual incentive bonus program. In general, management makes the initial recommendation for the financial target based upon our Company’s annual board-approved budget, as well as the bonus opportunity for each officer, and these recommendations are reviewed and discussed by the committee and its advisors. The major factors used in setting one or more targets for a particular year are the results for the most recently completed year and the budget for the current year. Other factors taken into account may include general economic and market conditions. Our human capital and compensation committee sets the final corporate performance goal during our first quarter, typically at a level our human capital and compensation committee believes is challenging, but reasonable, for management to achieve.

At the end of each year, our human capital and compensation committee determines the level of achievement for the specified financial goal and awards credit for the achievement of the goal as a percentage of the target bonus. Final determinations as to bonus levels are then based on that percentage. Actual bonuses are paid to the executives in the first quarter of the subsequent year.

Long-Term Equity Awards. We believe that providing a significant portion of our executive officers’ total compensation package in equity awards aligns the incentives of our executives with the interests of our stockholders and with our long-term success. By compensating our executives with our equity, executives receive a stake in the Company’s financial future, and the gains realized in the long term depend on the executives’ ability to drive our financial performance after grant. Equity incentive awards are also a useful vehicle for attracting and retaining executive talent in a competitive market.

Our human capital and compensation committee develops its equity award determinations based on its judgment as to whether the total compensation packages provided to our executive officers, including prior equity awards and the level of vested and unvested equity awards then held by each participating officer, are sufficient to retain, motivate, and adequately reward the executive officers. This judgment is based in part on information provided by benchmark studies. In addition, our human capital and compensation committee considers the accounting costs that will be reflected in our financial statements when establishing the forms of equity to be granted and the size of the grants, as well as the potential dilution associated with the equity awards.

We currently grant equity awards from the TTM Technologies, Inc. 2023 Incentive Compensation Plan (“2023 Plan”), which was adopted by our Board of Directors and approved by our stockholders and permits the granting of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, and other stock-based awards to our officers, directors, employees, and consultants. Historically, we have granted a mix of RSUs and PRUs to our CEO and NEOs in order to balance performance-contingent compensation for our executives.

Restricted Stock Units. RSUs are the right to receive one share of our common stock for each RSU upon the settlement date, which is the date on which certain conditions, such as continued employment with us for a pre- determined length of time, are satisfied. RSU awards reflect both increases and decreases in stock prices from the grant date market prices. RSUs further serve as a key retention vehicle as the award has retention value even during periods in which our trading price does not appreciate, supporting continuity among the senior management team.

The vesting schedule for RSUs granted to our executive officers and other employees provides that each award vests in three equal annual installments. Recipients may be entitled to a pro-rata amount of RSUs in the case of the recipient’s death, long term disability or “retirement” (voluntary termination by an employee who is at least 62 or government mandated retirement age, and has at least five years of continuous service).

Performance RSUs. In order to strengthen pay-for-performance, our human capital and compensation committee approved a long-term incentive program for our executive officers and certain other members of our senior management team. Our objective of this program is to incentivize performance against financial goals as well as long term total shareholder return.

Under the PRU Program, a target number of PRUs are awarded annually using a three-year performance period to encourage long-term retention of the executives of the Company. For the PRU awards, the number of shares of our common stock released at the end of the three-year period will range from zero to 2 times the target number of PRUs granted. The performance metrics of the PRU Program are (a) annual financial targets, which for each of the three years prior to the final vesting of the shares are based on total annual revenue and adjusted EBITDA (1), each of which is equally weighted, and (b), the three year TSR performance result, based on our Company's TSR over a three-year performance period relative to a TSR Peer Group of peer companies

selected by our human capital and compensation committee each year, which will be an additive component to the Company’s financial results of the aggregated three year measurement period.

Recipients of PRU awards generally must remain employed by us on a continuous basis through the end of the relevant performance period of three years in order to receive shares of common stock at the end of the three-year performance period. Recipients may also be entitled to a pro-rata amount of PRUs in the case of the recipient’s death, disability or retirement.

The key financial metrics of total annual revenue and adjusted EBITDA are equally weighted under our PRU Program. The metric of adjusted EBITDA is generally intended to focus our executives on tangible growth and cost containment. Adjusted EBITDA is also a complementary metric to the total annual revenue metric in the PRU Program. The combination of the two performance metrics limits the ability of an executive to be rewarded for taking excessive risk on behalf of our Company by, for example, seeking high-cost revenue-enhancing opportunities at the expense of adjusted EBITDA, since performance is required on both metrics to maximize the issuance of common stock under the PRU Program.

The TSR adder is intended to ensure that shares of common stock issued at the end of the three-year period reflect both the Company's performance over the period as well as our stock performance for each three-year performance period. Additionally, the use of the TSR component as used on our PRU plans also is intended to enhance the award of common stock should our stock performance outperform the TSR Peer Group.

The PRU Recipient can earn the PRU based on the Company’s performance in (a) achieving annual financial performance goals established by the Committee, and (b) achieving a total stockholder return (“TSR”) over three successive fiscal years. The amount of the PRU Award will range from 0% to 200% of the annual target goals as determined after the end of each year based upon the Company’s performance against the annual financial performance goals and three-year TSR as reviewed and approved by the Committee. No PRU will be awarded if performance is below minimum levels.

The table below illustrates the multi-year components of the 2025 PRUs, including the weighting.

At the Target Level, 13.33% of the Target Amount will vest based on the Company’s revenues, and 13.33% of the Target amount will vest based on the Company’s adjusted EBITDA in the first fiscal year of the program relative to the target milestone set forth by the Committee at the beginning of each year. Therefore, at the Target Levels, 26.67% of the Target Amount will be based on the Company’s financial performance with respect to one or more target milestones established by the Committee for each fiscal year.

As revenue and adjusted EBITDA goals are achieved, a portion of the Target Amount shall be credited in the Recipient’s PRU account. The amounts credited for each fiscal year in connection with each of the annual revenue goal and adjusted EBITDA goal as a percentage of 13.33% will be as follows: 0% if performance is below minimum level, 6.67% if performance is at minimum level of 60% of the annual goal (the “Minimum Level vs. the Goal”), 13.33% if performance is equal to the annual goal (the “Target Level”), and 26.67% if performance is at or above maximum level of 120% of the annual goal (the “Maximum Level vs. the Goal”). For performance between the Minimum Level and the Target Level, a proportionate percentage between 6.67% and 13.33% will be applied based on relative performance. For performance between the Target Level and the Maximum Level,

a proportionate percentage between 13.33% and 26.67% will be applied based on relative performance between target and maximum. The PRUs earned for performance against the annual revenue and adjusted EBITDA goals vest at the end of three years.

The portion of the PRUs earned for relative TSR is weighted 20% of the total. The threshold level of TSR performance is at the 25th percentile of the TSR Peer Group at the end of the three year period (the “Minimum TSR Level”), the target level performance is the 50th percentile of the TSR Peer Group (the “Target Level”) and the maximum level of TSR performance shall be at or above the 75th percentile of the TSR Peer Group at the end of the three year period (the “Maximum TSR Level”). The TSR Component will be based on the Company’s fiscal three-year TSR as compared to the fiscal three-year TSR for each company listed in the TSR Peer Group over the same period. For performance between the Minimum TSR Level and the Target Level, a proportionate TSR Component percentage between 50% and 100% will be applied based on actual relative performance and for performance between the Target Level and the Maximum TSR Level, a proportionate TSR Component percentage between 100% and 200% will be applied based on actual relative performance. The TSR Component will be equal to zero if the Minimum TSR Level is not met, resulting in no payout for this stand-alone component of the PRU Program. The TSR Component is 20% of the Target Amount at the Target Level performance after the three-year period. The TSR Component is 40% of the Target Amount at or above the Maximum TSR Level performance at the end of the three-year period. The chart below illustrates the TSR Component with respect to the Company’s TSR performance relative to the TSR of the TSR Peer Group during the Performance Period:

Equity Award Mix in 2025. In determining the ratio between PRU and time-vested RSU awards, the human capital and compensation committee reviewed and took into consideration the desire to ensure that a significant portion of equity compensation be tied to our Company’s performance against our peers. Additionally, the human capital and compensation committee desired to ensure that its equity program was competitive, provided long-term retention of critical leadership talent, and best aligned pay practices with the interests of our stockholders. The following table sets forth the value of our 2025 equity awards and the number of time-vested RSUs and (at target) PRUs awarded to our NEOs for 2025.The RSUs and PRU grants are determined as a value, with a majority in PRUs. The number of shares is determined using the six-month simple average price to neutralize volatility. In 2025, the stock price was increasing, so the six-month average stock price was lower than the closing price on the date of grant. As a result, the equity compensation grant values approved by the human capital and compensation committee are lower than the amounts shown in the Grants of Plan-Based Award Table in this proxy statement. The table below shows both the approved grant value and the number of shares granted after considering the six-month trailing average stock price.

The annual financial performance goal or goals for future years will be established in the first quarter of each of those subsequent years. Whether any units credited under our future grants will be paid out in shares at the end of the applicable three-year period will depend on future results and our TSR during that period, neither of which is determinable until the end of the three-year period.

Settlement of PRUs for 2023-2025 Performance Period. The PRUs granted in 2023 have vested and resulted in the issuance of shares to some of our executive officers. The below charts detail the calculations of the PRUs that vested in 2025 and were released in 2026. The overall result was:
