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:

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 III directors; (2) “FOR” approval of an amendment of our certificate of incorporation to provide for the exculpation of officers; (3) “FOR” approval of an amendment of our certificate of incorporation to provide that stockholders may remove any or all directors, with or without cause; (4) “FOR” approval of an amendment of our certificate of incorporation to eliminate the requirement that certain amendments thereto be approved by at least 80% of the outstanding shares; (5) “FOR” approval of amendments of our bylaws arising from the Special Board Resolution; (6) “FOR” approval of amendments of our bylaws to provide (a) modifications to the advance notice requirements applicable to director nominations submitted by stockholders, (b) a majority approval standard for uncontested elections of directors, (c) that stockholders may remove directors with or without cause, and (d) miscellaneous amendments to our bylaws; (7) “FOR” approval of an amendment of our bylaws to eliminate the requirement that certain amendments thereto be approved by at least 80% of the shares entitled to vote; (8) “FOR” approval on an advisory, non-binding basis, of the compensation of our named executive officers; and (9) “FOR” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 30, 2024. 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.

Only stockholders of record at the close of business on March 13, 2024, 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.

Stockholder of Record. If you are the stockholder of record (that is, the shares are registered directly in your name with our transfer agent, 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 April 1, 2024, and through 11:59 p.m., Eastern Time, on May 7, 2024.

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, 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 Regularity 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.”

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.

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, American Stock Transfer & Trust Company, 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.

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.

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, [•] 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.

Proposal One — Election of Directors. The three persons receiving the largest number of “for” votes of our common stock present in person or by proxy at the meeting and entitled to vote (a plurality) will be elected as directors. Stockholders do not have the right to cumulate their votes for directors.

Proposal Two — Approval of an amendment of our certificate of incorporation to provide for the exculpation of officers as permitted by Delaware law. The affirmative vote of a majority of the shares of our common stock outstanding as of the record date for the annual meeting and entitled to vote on the matter will be required for approval of Proposal Two.

Proposal Three – Approval of an amendment of our certificate of incorporation to provide that stockholders may remove any or all directors, with or without cause, as permitted by Delaware law. The affirmative vote of 80% of the shares of our common stock outstanding as of the record date for the annual meeting and entitled to vote on the matter will be required for approval of Proposal Three.

Proposal Four – Approval of amendment of our certificate of incorporation to eliminate the requirement that certain amendments thereto be approved by at least 80% of the outstanding shares of all capital stock. The affirmative vote of 80% of the shares of our common stock outstanding as of the record date for the annual meeting and entitled to vote on the matter will be required for approval of Proposal Four.

Proposal Five – Approval of amendments of our bylaws arising from the Special Board Resolution adopted by the Board of Directors in February 2023. The affirmative vote of 80% of the shares of our common stock entitled to vote on the matter will be required for approval of Proposal Five.

Proposal Six – Approval of amendments of our bylaws to provide (a) modifications to the advance notice requirements applicable to director nominations submitted by stockholders, (b) a majority approval standard for uncontested elections of directors, (c) that stockholders may remove any or all directors, with or without cause, and (d) miscellaneous amendments to our bylaws. The affirmative vote of 80% of the shares of our common stock entitled to vote on the matter will be required for approval of Proposal Six.

Proposal Seven – Approval of an amendment of our bylaws to eliminate the requirement that certain amendments thereto be approved by at least 80% of the shares entitled to vote upon such amendment. The affirmative vote of 80% of the shares of our common stock entitled to vote on the matter will be required for approval of Proposal Seven.

Proposal Eight — Advisory, Non-Binding Vote on 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 our 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 Nine — 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 our independent registered public accounting firm for the fiscal year ending December 30, 2024

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).

Proposal One, Two, Three, Four, Five, Six, Seven and Eight 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 and Eight. Broker non-votes will have the effect of votes against Proposals Two, Three, Four, Five, Six and Seven.

The ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 30, 2024 (Proposal Nine) 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 Nine.

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

With respect to Proposal One (the election of directors), you may vote “FOR ALL NOMINEES,” “WITHHOLD AUTHORITY FOR ALL NOMINEES,” or “FOR ALL EXCEPT” one or more of the nominees (which will have the effect of withholding your vote for the designated nominees). Votes that are withheld will not be included in the vote tally for the election of directors (Proposal One) and will not affect the results of that vote.

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 2024 annual meeting will serve for a term expiring at the 2027 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 III directors.

Our Board of Directors has nominated Rex D. Geveden, Pamela B. Jackson and John G. Mayer as class III directors. Mr. Geveden, Ms. Jackson and Mr. Mayer currently serve as class III directors. Mr. Geveden, Ms. Jackson and Mr. Mayer will stand for re-election at the 2024 annual meeting.

Thomas T. Edman and Chantel E. Lenard serve as class I directors and their terms will expire at the annual meeting of stockholders in 2025. Kenton K. Alder, Julie S. England and Philip G. Franklin serve as class II directors and their terms will expire at the annual meeting of stockholders in 2026. In addition, pursuant to our Corporate Governance Guidelines, Dov S. Zakheim, who currently serves as a class I director, must submit his resignation and retire from our Board of Directors at the 2024 annual meeting. Because Dr. Zakheim will have attained the mandatory retirement age of 75, our Board of Directors may no longer defer and is obligated to accept his resignation. Our nominating and corporate governance committee is currently identifying and evaluating qualified individuals to be considered and ultimately recommended to the Board as the candidate to fill the vacancy that will be created by Dr. Zakheim's resignation and retirement from the Board.

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, such that our Board is comprised entirely of U.S. Citizens, and at least three such members maintain national 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. In addition, per the terms of the SBR, no foreign 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 Defense. As such, over 425 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 Agreement with DCSA codifies 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. Department of Defense 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 III directors.

The following table, together with the accompanying text, sets forth certain information with respect to each of our directors and director nominees as of the date of this Proxy Statement:

Board Diversity Matrix*

The Company’s Board Diversity Matrix identifies each director’s self-identified diversity characteristics, as follows:

* As of March 1, 2024. There have been no changes to this information since the publication of the Board Diversity Matrix dated as of March 16, 2023, which is included in our definitive proxy statement for our 2023 annual meeting, as filed with the SEC on March 16, 2023.

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. Alder, Franklin, Geveden and Mayer, Mses. Jackson, England and Lenard, and Dr. Zakheim 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. Mr. Edman is not considered to be an independent director as a result of his position as an executive officer of our Company.

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. Each of our committees, with the exception of the government security committee (of which Mr. Edman is a member), 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 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.

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 in line with our corporate values of teamwork, integrity, clear communication, and performance excellence. 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. The foundation of TTM’s strategic vision is our corporate culture and its way of doing business with integrity, teamwork, clear communication, and performance excellence. 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. Along with the TTM Values and our Leadership Principles, we discuss and act in accordance with, and provide annual training for, our Code of Conduct, which outlines our expectations and provides guidance for all employees. Our Code of Conduct includes topics such as anti-corruption, discrimination, harassment, privacy, appropriate use of company assets, protecting confidential information, and reporting 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 a confidential outlet 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 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 retention. We believe the emphasis we place on selecting and training new hires as well as and coaching supervisors positively impacts the work environment. Our leadership principles of results, communications, collaboration and career development are designed to improve the employee experience and strengthen working relationships. Through internal surveys, it is clear our employees value their relationships with their supervisors, career opportunities and the corporate culture.

Management Policies and Communication. How we manage and leverage our human capital is essential in executing our strategy. At TTM, 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 such as those outlined in the NIST SP 800-171 and evolving Cybersecurity Maturity Model Certification (CMMC) frameworks. 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 annually, on the ever-present threat of cybersecurity helps 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 five meetings (regular and special) during 2023. 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 2023, and (ii) the total number of meetings held by all committees of our Board of Directors on which such person served during 2023. We have adopted a policy encouraging each of our directors to attend each annual meeting of stockholders and, to the extent reasonably practicable, we regularly schedule a meeting of the Board of Directors on the same day as the annual meeting of stockholders. All of our directors attended the 2023 annual meeting of stockholders.

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:

* Pursuant to our Corporate Governance Guidelines, Dr. Zakheim will retire from the Board of Directors and his term of office will conclude at the 2024 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) and Mayer, Ms. Jackson and Dr. Zakheim, each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The Board of Directors has determined that each of Mr. Franklin and Dr. Zakheim 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 2023.

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 provides 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, monitors talent and career development and retention of our employees and oversees the promotion of diversity and inclusion within the organization. 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, from time to time, 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. 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 Messrs. Geveden (chair), Ms. Jackson and Ms. Lenard, 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 2023.

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.

Our human capital and compensation committee retained Exequity as our compensation consultant for 2023 to provide an independent review 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 pursuant to SEC and NASDAQ rules and concluded that Exequity is independent and that their work has not raised any conflict of interest. For further discussion of the work conducted by our compensation consultants, see “Compensation Discussion and Analysis – Role of the Human Capital and Compensation Committee.”

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 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 evaluation of 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), and (b) the individual’s written consent to being named in a proxy statement as a nominee and to serving as a director if elected. The stockholder making the nomination must also provide the information required by our current bylaws relating to such stockholder, including information pertaining to ownership of our capital stock, and must make certain representations relating to voting intent and delivery of proxies. The stockholder’s nominee must also deliver to our secretary a written questionnaire with respect to the background and qualification of such person and the background of any other person or entity on whose behalf the nomination is being made. 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 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, diversity, 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.

* Self-reported by each Director

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.

The charter of our nominating and corporate governance committee provides that the value of diversity on our Board of Directors should be considered, and the nominating and corporate governance committee includes diversity as one of its criteria for board composition. While we do not have a formal policy outlining the diversity standards to be considered when evaluating director candidates, our objective is to foster diversity of thought on our Board of Directors. To accomplish that objective, the nominating and corporate governance committee considers ethnic and gender diversity, as well as differences in perspective, orientation, professional experience, education, national security qualifications, skill and other qualities in the context of the needs of our Board of Directors. The nominating and corporate governance committee evaluates its effectiveness in achieving diversity on the Board of Directors through its annual review of board member composition, which includes an assessment of directors’ ethnicity, gender, and industry experience, prior to recommending nominees for election.

The current members of our nominating and corporate governance committee are Mses. England (chair) and Lenard and Mr. Mayer, each of whom is an independent director under NASDAQ listing standards as well as under SEC rules. The nominating and corporate governance committee held five meetings during 2023.

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. Department of Defense, 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). In February of 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. The effective date of the SBR is February 2, 2023. The SBR codifies 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 of our Board of Directors, consists of at least 3 Board members that hold a National Security Clearance. 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. DoD 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 foreign citizen will be allowed to sit on TTM’s Board. The current members of our government security committee are Ms. England, Dr. Zakheim (chair), and Messrs. Alder, Edman, and Geveden. The government security committee held four meetings during 2023.

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 Mr. Edman 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 eight independent members and one non-independent member, specifically Mr. Edman, our President and Chief Executive Officer. 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.

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 have strong national security qualifications and that all Directors be U.S. citizens. Our current Board of Directors meets the composition criteria and our board has determined to maintain a classified 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, 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, and finance, environmental, health and cybersecurity 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.

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. Accordingly, our Corporate Governance Guidelines provide that our independent directors are prohibited from selling the shares that they are awarded under the Company’s Long Term Equity Incentive Plans until such time as they retire from our Board and are expected over time to beneficially own shares of our common stock (including shares owned outright, unvested shares, restricted stock units, and stock options) 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. All of our 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 47.

DIRECTOR COMPENSATION

Commencing with the second quarter of 2023, our non-employee directors receive the following cash compensation on an annual basis: an annual cash retainer of $75,000, 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: $22,000 to our audit committee chair, $17,000 to our human capital and compensation committee chair, $15,000 to our government security committee chair, and $17,000 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, commencing with the second quarter of 2023, our non-employee directors are granted the following equity compensation on an annual basis: the Chair of the Board receives restricted stock units (“RSUs”) having a value on the award date of $210,000 and each non-employee director receives restricted stock units having a value on the award date of $160,000, in each case 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 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, delivery of the shares of common stock underlying the RSUs is deferred until retirement from the Board of Directors (or until one year after retirement in the case of certain prior grants).

Mr. Edman is not compensated for his service as a director. Mr. Edman’s compensation as our Chief Executive Officer and President 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. One of our directors participated in the Executive and Director Deferred Compensation Plan in 2023.

Compensation Overview – Alignment of Compensation and Performance

Our primary goal is to tie Company Executive's compensation closely with performance. The information below provides an executive summary of our Company’s financial performance for fiscal year 2023 and how pay is aligned with performance.

KEY ACCOMPLISHMENTS IN 2023

TTM’s commitment to its strategy of diversification, differentiation and discipline led to TTM’s continued financial strength in 2023. Due to disciplined operations and cost controls, we generated Non-GAAP net income of $139.5 million in 2023. For a discussion explaining the use of the 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 solid financial performance despite a challenging macroeconomic environment.

ALIGNMENT OF PAY AND PERFORMANCE

The charts below measure the total compensation for the CEO and the average total compensation for our NEOs for the past three years.

These charts demonstrate consistent alignment in performance-based compensation for the three-year period with the Company’s performance over such three-year period. The Company’s performance and the price of the Company’s common stock on the NASDAQ directly impacts total compensation realized by our executives.

2023 SAY ON PAY VOTE

At our 2023 annual meeting, our stockholders overwhelmingly approved, on an advisory basis, the compensation of our NEOs described in our 2023 proxy statement.
