    Dear Stockholder:

    You are cordially invited to the Annual Meeting of Stockholders of Centuri Holdings, Inc. (“we,” “us,” “our,” the “Company” or “Centuri”), scheduled to be held on May 19 at 2:00 p.m. Eastern Time in a completely virtual format at http://www.virtualshareholdermeeting.com/CTRI2026.

    On behalf of Centuri’s Board of Directors, we thank you for your support throughout a remarkable year for the Company. We sincerely value your investment in our business and will continue working to deliver value and deepen the trust you have placed in us.

    2025 was a pivotal year for Centuri as we realized full separation from our former parent company. Reflecting on the year’s end, we are proud of our achievements, which included record revenue for the year and improved company earnings and balance sheet health, as well as the expansion of our operations through the acquisition of Connect Utility Services in Atlantic Canada.

    Now, charting our course as a standalone public company, we are well positioned to capitalize on the strong tailwinds in our sector while staying focused on capital discipline and strong work execution. We are actively mapping a deliberate strategy to achieve profitable growth while delivering enduring value and meeting commitments to all of our stakeholders.

    On behalf of Centuri’s Board of Directors and our more than 9,600 employees working across North America, we thank you for your continued investment and trust in Centuri.

    Sincerely yours,

    Chris Brown Signature.jpg
    Christian I. Brown
    President and Chief Executive Officer

    Important Notice Regarding the Availability of Proxy Materials for
    the Annual Meeting to be Held on May 19, 2026

    Pursuant to the rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the internet. Accordingly, we are sending a Notice Regarding the Internet Availability of Proxy Materials (the “Notice”) to certain of our stockholders of record. We are also sending a paper copy of the proxy materials and Proxy Card to other stockholders of record who have indicated they prefer receiving such materials in paper form. Brokers and other nominees who hold shares on behalf of beneficial owners will be sending their own similar Notice. We intend to commence mailing the Notice or paper copies of this proxy statement and Proxy Card, as applicable, on or about April 6, 2026 to all stockholders entitled to vote at the Annual Meeting.

    Stockholders will have the ability to access the proxy materials on the website referred to in the Notice or may request to receive a paper copy of the proxy materials by mail or electronic copy by electronic mail on a one-time or ongoing basis. Instructions on how to request a printed copy by mail or electronically may be found on the Notice.

    What is the purpose of the Annual Meeting?
    At the Annual Meeting, stockholders will be asked to vote on the following matters:
    •The election of nine directors of the Company;
    •The approval, on a non-binding, advisory basis, of the Company’s executive compensation;
    •The approval of the Centuri Employee Stock Purchase Plan;
    •The ratification of the selection of PricewaterhouseCoopers LLP as the independent registered public accounting firm for the Company for fiscal 2026; and
    •Any other matter that may properly come before the Annual Meeting or any adjournment thereof.

    How do I attend the Annual Meeting?
    The Annual Meeting will be a completely virtual meeting of stockholders. You will be able to submit questions prior to the Annual Meeting and vote online by logging on to www.proxyvote.com using the 16-digit control number found in the proxy materials previously distributed to you. Attendance at the Annual Meeting will be limited to stockholders of the Company as of March 23, 2026, the record date for the Annual Meeting, and guests of the Company. You will not be able to attend the Annual Meeting in person at a physical location.

    Table of Contents

    Although the meeting webcast will begin at 2:00 p.m. Eastern Time on May 19, 2026, we encourage you to access the meeting site 15 minutes prior to the start time to allow ample time to log into the meeting webcast and test your computer system.

    Technical Disruptions. In the event of any technical disruptions or connectivity issues during the course of the Annual Meeting, please allow for some time for the meeting website to refresh automatically, and/or for the meeting operator to provide verbal updates.

    Stockholder List. As required by Delaware law, we will make available a list of registered stockholders as of March 23, 2026, the record date of the Annual Meeting, for inspection by stockholders for any purpose germane to the Annual Meeting from May 8, 2026, through May 18, 2026 at our headquarters located at 19820 North 7th Avenue, Suite 120, Phoenix, Arizona 85027. If you wish to inspect the list, please submit your request, along with proof of your share ownership, by e-mail to [email protected].

    How can I submit questions prior to and during the Annual Meeting?
    Prior to the Annual Meeting, you may submit questions pertaining to the business of the meeting by accessing www.proxyvote.com using the 16-digit control number found in the proxy materials distributed to you any time before 11:59 p.m., Eastern Time, on the day before the meeting. During the Annual Meeting, as well as 15 minutes prior to the start time, stockholders will also be able to submit questions through the online platform used for the Annual Meeting at http://www.virtualshareholdermeeting.com/CTRI2026. The Company will respond to germane questions during the meeting and will endeavor to answer as many questions submitted by stockholders as time permits. However, if there are questions pertinent to matters properly before the Annual Meeting that cannot be answered during the meeting due to time constraints, we will post answers to a representative set of such questions at the “Investor Relations” section of the Company’s website at www.centuri.com. The questions and answers will be available as soon as practicable after the Annual Meeting and will remain available until we file our proxy statement for the 2027 Annual Meeting of Stockholders. We reserve the right to edit questions to remove inappropriate language and to exclude questions regarding topics that are not pertinent to meeting matters. If we receive substantially similar questions, we may group such questions together and provide a single response.

    Who is entitled to vote at the Annual Meeting?
    Only stockholders of record at the close of business on March 23, 2026, the record date for the Annual Meeting, are entitled to receive notice of and to vote at the Annual Meeting. If you are a stockholder of record on that date, you are entitled to vote all of the shares that you held on that date at the Annual Meeting, or any adjournment or postponement of the Annual Meeting.

    How many votes do I have?
    You have one vote for each share of Common Stock owned as of the record date for the Annual Meeting.

    How do I vote?
    If your shares are registered directly in your name, you are the holder of record of those shares and can vote your shares either by proxy, whether or not you attend the virtual Annual Meeting, or by ballot by attending the virtual Annual Meeting. Whether or not you plan to attend the virtual Annual Meeting, we encourage you to submit your proxy promptly to ensure that your votes are counted. You may still attend the virtual Annual Meeting and vote by ballot even if you have already submitted a proxy.

    Stockholders have a choice of voting online, by telephone, by mail, or at the Annual Meeting:
    •If you received a printed copy of the proxy materials, please follow the instructions on your Proxy Card or voter instruction form. Your Proxy Card or voter instruction form provides information on how to vote.
    •If you received a Notice of Internet Availability, please follow the instructions on the notice. The Notice of Internet Availability provides information on how to vote.
    •If you received an e-mail notification, please click on the link provided in the e-mail notification and follow the instructions on how to vote.

    If you hold your shares in a brokerage account or through a bank, trust or other nominee (collectively, a “broker”), you are the beneficial owner of the shares, and the shares are held in “street name.” You will receive instructions from your broker on how to vote your shares. Your broker will allow you to deliver your voting instructions over the internet and may also permit you to

    2026 Proxy Statement

    Table of Contents
    submit your voting instructions by telephone or by completing, dating and signing the Proxy Card included with your proxy materials if you request a paper copy of them by following the instructions on the notice provided by your broker.

    Can I revoke or change my vote?
    Yes, a record holder can revoke or change a vote at any time prior to the voting of shares at the Annual Meeting by (a) casting a new vote by telephone or online; (b) sending a new Proxy Card with a later date; (c) sending a written notice of revocation that is received on or prior to May 18, 2026, by mail to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717; or (d) voting by ballot at the virtual Annual Meeting. If a broker, bank, trustee or other nominee holds your shares, you must contact them in order to find out how to change your vote.

    What are the Board’s recommendations?
    The Board’s recommendations are set forth within the description of each proposal in this Proxy Statement. In summary, the Board recommends a vote:
    •FOR the election of the slate of directors nominated by the Board (see Proposal 1);
    •FOR the approval of the Company’s executive compensation (see Proposal 2);
    •FOR the approval of the Centuri Employee Stock Purchase Plan (see Proposal 3); and
    •FOR the ratification of the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for fiscal 2026 (see Proposal 4).

    How many votes must be present to hold the Annual Meeting?
    In order to conduct business at the Annual Meeting, the holders of a majority of the outstanding shares of Common Stock entitled to vote generally for the election of directors must be present at the meeting. Shares are counted as present at the meeting if (i) you are present online and vote at the meeting, or (ii) you have properly and timely submitted your proxy as described above under “How do I attend the Annual Meeting?” This is called a quorum. As of the close of business on March 23, 2026, 100,844,515 shares of Common Stock were outstanding and entitled to vote. Proxies received but marked as abstentions will be included in the calculation of the votes considered to be present at the meeting.

    What is a “broker non-vote”?
    A “broker non-vote” occurs when a broker lacks discretionary authority to vote on a “non-routine” proposal and a beneficial owner fails to give the broker voting instructions on that matter. The rules of the New York Stock Exchange (“NYSE”) determine whether matters presented at the Annual Meeting are “routine” or “non-routine” in nature. The election of directors is considered a “non-routine” matter. The advisory vote to approve the Company’s executive compensation is considered a “non-routine” matter. Similarly, the vote to approve the Centuri Employee Stock Purchase Plan is considered a “non-routine” matter. Therefore, beneficial owners who hold their shares in street name must provide voting instructions to their brokers in order for their broker to vote their shares on these matters. As a result, if you do not instruct your broker on how to vote your shares, then your shares will not be voted on these proposals. We urge you to instruct your broker about how you wish your shares to be voted. The ratification of the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for fiscal 2026 is considered a “routine” matter, and brokers will have discretionary authority to vote on this matter without any instruction from the beneficial owners.

    What vote is required to approve each Proposal?
    The nine nominees for director who receive the highest number of votes “FOR” their election will be elected as directors. This is called a “plurality vote.” The affirmative vote of the holders of a majority of the shares of Common Stock represented in person or by proxy and entitled to vote on the matter at the Annual Meeting will be required to (i) approve, on an advisory basis, the Company’s executive compensation, (ii) approve the Centuri Employee Stock Purchase Plan, and (iii) ratify the appointment of PricewaterhouseCoopers LLP as the independent registered public accounting firm for the Company for fiscal 2026.

    How are my votes counted?
    •Election of Directors: You may vote “FOR ALL,” or “WITHHOLD ALL,” or “FOR ALL EXCEPT.” If you mark “FOR ALL,” your votes will be counted for all of the director nominees.

    the Board will consider the outcome of the vote when making future executive compensation decisions. Abstentions will have the same effect as a vote AGAINST this proposal, and broker non-votes will have no effect on the outcome of this proposal.
    •Approval of the Centuri Employee Stock Purchase Plan: You may vote “FOR,” “AGAINST,” or “ABSTAIN” with respect to approval of the Centuri Employee Stock Purchase Plan. Abstentions will have the same effect as a vote AGAINST this proposal, and broker non-votes will have no effect on the outcome of this proposal.

Abstentions will have the same effect as a vote AGAINST this proposal, and broker non-votes will have no effect on the outcome of this proposal.

    We will appoint an independent inspector of election in advance of the meeting to tabulate votes, to ascertain whether a quorum is present, and to determine the voting results on all matters presented to Company stockholders.

    What if I do not vote for any or all of the matters listed on my Proxy Card?
    As a stockholder of record, if you return a signed Proxy Card without indicating your vote on any or all of the matters to be considered at the Annual Meeting, your shares will be voted “FOR” the director nominees listed on the Proxy Card, “FOR” the approval of the advisory vote to approve executive compensation, “FOR” the approval of the Centuri Employee Stock Purchase Plan and “FOR” the ratification of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for fiscal 2026, if you have not voted otherwise on a particular proposal. With respect to any other matter that properly comes before the Annual Meeting, Gregory A. Izenstark and Jason S. Wilcock, the proxies designated by the Board and identified in the accompanying Proxy Card, will vote all proxies granted to them at their discretion.

    What is “Householding”?
    In order to reduce expenses, we are taking advantage of certain SEC rules, commonly known as “householding,” that permit us to deliver, in certain cases, only one Notice, Annual Report, or Proxy Statement, as applicable, to multiple stockholders sharing the same address, unless we have received contrary instructions from one or more of the stockholders. If you received a householded mailing this year and would like to have additional copies of the Notice, the Annual Report, Proxy Statement, or other proxy materials sent to you, please submit your request directed to our Corporate Secretary, Centuri Holdings, Inc., 19820 North 7th Avenue, Suite 120, Phoenix, Arizona 85027, or by telephone at (623) 582-1235.

    GOVERNANCE OF THE COMPANY
    Board of Directors
    Under the provisions of the Delaware General Corporation Law and the Company’s bylaws, the Company’s business, property and affairs are managed by or under the direction of the Board. The Board is kept informed of the Company’s business through discussions with the Chief Executive Officer (the “Chief Executive Officer” or the “CEO”) and other officers and by reviewing reports and other materials provided to it by management at the Board and committee meetings.

    Director Independence
    The Board assesses on a regular basis, and at least annually, the independence of directors and, based on the recommendation of the Nominating and Corporate Governance Committee of the Board (the “Nominating and Corporate Governance Committee”), makes a determination as to which members are independent. The Board determines the independence of our directors by applying the independence principles and standards established by the NYSE and included in the Company’s Corporate Governance Guidelines. The Board determined that directors Dustin DeMaria, Julie A. Dill, Andrew W. Evans, Christopher A. Krummel, Anne L. Mariucci, Steven E. Nielsen and Charles R. Patton have no material relationships with the Company and are independent (the “Independent Directors”).

    In making these determinations, the Board reviewed all transactions or relationships with the Company using a definition of “material relationships” that (i) includes the criteria listed in Section 303A of the listing requirements of the NYSE and (ii) includes, on a case-by-case basis, such other criteria that may be deemed to affect a director’s independence, including without limitation, relationships that would require disclosure under Item 404 of Regulation S-K (“Item 404”) of the Securities Exchange Act of 1934 (“Exchange Act”) and non-tariff transactions with the Company in excess of the Item 404 threshold. The definition of “material relationships” for directors on the Audit Committee of the Board (the “Audit Committee”) also includes the criteria listed in Section 10A(m)(3) of the Exchange Act. The definition of “material relationships” for directors serving on the Compensation Committee of the Board (the “Compensation Committee”) also includes the criteria listed in Section 16(b) of the Exchange Act. The independence criteria used are included in the Company’s Corporate Governance Guidelines, which are available on the Company’s website at www.centuri.com. The Board based its independence determination primarily on a review of the responses of the directors and officers to questions regarding employment and compensation history, affiliations and family relationships, discussions with directors, and a review of Company and subsidiary payment histories.

    Controlled Company Status
    The Company was previously a privately held subsidiary of Southwest Gas Holdings, Inc. (“Southwest Gas Holdings”) and qualified as a “controlled company” as defined under the corporate governance rules of the NYSE, and therefore it took advantage of exemptions from certain corporate governance requirements of the NYSE. Previously, Southwest Gas Holdings’ chief executive officer and director, Ms. Karen Haller, served as the Chair of the Board and a member of its Compensation Committee pursuant to the Company’s exemption from the NYSE requirement that the Board’s compensation committee must be composed of only independent directors. Subsequent to Southwest Gas Holdings’ ownership exit from the Company through a series of transactions that completed on September 5, 2025, the Company became a standalone company that no longer qualified as a “controlled company,” and was required to fully implement the corporate governance requirements of the NYSE within the applicable transition periods. As a result, the Board appointed Mr. Christopher Krummel as the independent Chair of the Board, effective September 15, 2025, replacing Ms. Haller, who has remained a member of the Board. Ms. Haller also resigned from the Board’s Compensation Committee on the same date.

    Board Meetings 
    The Board meets regularly throughout the year and also holds special meetings from time to time. The Board held four regular meetings and five special meetings in 2025. During 2025, each member of the Board attended at least 75% of the aggregate of (i) the total number of meetings of the Board held during the period for which he or she has been a director and (ii) the total number of meetings held by all committees of the Board on which he or she served during the periods that he or she served.

    Pursuant to the Corporate Governance Guidelines, the Company’s non-management directors are expected to meet in executive session at least four times per year, and its independent directors are expected to separately meet in a private session at least once annually. The director who presides at these meetings will be appointed by the non-management and independent directors, respectively.

    Board Leadership Structure
    The policy of the Board is that the role of Chair should be separate from that of the Chief Executive Officer. The Chair is appointed annually by the full Board following an in-depth assessment by the Nominating and Corporate Governance
    Logo.jpg
    6
    2026 Proxy Statement

    Table of Contents
    Committee regarding the needs of the Board and potential candidates for the position, and a recommendation to the Board by the Nominating and Corporate Governance Committee. The Board believes that this leadership structure is the appropriate structure for the Company because it aids the Board’s oversight of management. It is the Board’s intention to reappoint Mr. Krummel as Chair, subject to his reelection as a director at the Annual Meeting. As a member of the Board, Mr. Krummel may represent the Board in meetings with various constituencies, including investors. Prior consultation with Company management in these instances helps to ensure consistency and context for Board member communications.

    The Board believes the structure described above provides strong leadership for the Board, while positioning the Chief Executive Officer as the leader of the Company for its investors, counterparties, employees and other stakeholders. The Board believes that the current structure helps ensure independent oversight of the Company and allows the Chief Executive Officer to focus his energies on management of the Company.

    All members of the Board are independent, with the exception of Ms. Haller and Mr. Christian I. Brown, the Chief Executive Officer. A number of the independent Board members are currently serving or have served as directors or as members of senior management of other public companies and large institutions. The Board believes that the number of independent, experienced directors that make up our Board, along with the oversight of the Board by the non-executive Chair, benefits the Company and its stockholders.

    The Board recognizes that in the event that the circumstances facing the Company change, a different leadership structure may be in the best interests of the Company and its stockholders.

    Risk Oversight
    Our management has day-to-day responsibility for assessing and managing our risk exposure and the Board and its committees oversee those efforts, with particular emphasis on the most significant risks facing the Company. Each committee will report to the full Board on a regular basis, including as appropriate with respect to the committee’s risk oversight activities.

    Board/Committee
    Primary Areas of Risk Oversight
    Full Board
    Risks associated with the Company’s strategic plan, acquisition and capital allocation program, capital structure, liquidity, organizational structure and other significant risks, and overall risk assessment and risk management policies.
    Audit Committee
    Risks related to financial controls, legal and compliance risks and major financial, privacy, security (including cybersecurity and data privacy), operational and business continuity risks.
    Compensation Committee
    Risks associated with compensation policies and practices.
    Nominating and Corporate Governance Committee
    Risks related to corporate governance and management of the Board.

    Analysis of Risk in Company Executive Compensation Policies
    Formally on an annual basis, and in its execution and consideration of compensation plans, Company management reviews, analyzes and considers whether the Company’s compensation policies and practices encourage unnecessary or excessive risk taking that is reasonably likely to have a material adverse effect on the Company. One of the primary purposes of this review is to ensure that the Company’s incentive compensation programs do not inappropriately encourage unnecessary or excessive risk taking at any level in the organization that would be reasonably likely to have a material adverse effect on the Company. The Compensation Committee oversees the risk review process. In 2025, management concluded, after discussion with the Compensation Committee, that the Company’s compensation policies and practices do not encourage executives or other employees to take inappropriate risks that are reasonably likely to have a material adverse effect on the Company.

    Cybersecurity Oversight
    Cybersecurity risk is overseen by the Board along with subject matter experts within the Company. It is a priority regularly addressed by the Board with the relevant functional leaders of the Company. The Board receives regular cybersecurity briefings from the Company’s Vice President of Information Technology, who has operational oversight over the cybersecurity program. During each of its regularly scheduled committee meetings, the Audit Committee discusses with management and auditors the Company’s guidelines and policies with respect to risk assessment and management, which encompass cybersecurity program areas of emphasis, data privacy and security, business continuity, and operational risks, and provides relevant updates.
    Logo.jpg

    Table of Contents
    Quarterly, the Vice President of Information Technology provides a formal cybersecurity update to the Company’s Chief Legal & Administrative Officer highlighting relevant key metrics, events, efforts, risks, and risk mitigation activities. The Board receives these updates so that it can ensure the proper oversight and management of the cybersecurity program and awareness of current and emerging cybersecurity threats to the Company.

    Sustainability
    We advance sustainability by integrating corporate responsibility values into every area of our business, as well as embedding them within our governance structure. Responsibility for sustainability oversight rests with the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee receives regular reports from management about sustainability performance and policies, and ensures compliance with applicable laws and regulations. The Nominating and Corporate Governance Committee reports to the Board on the Company’s sustainability initiatives and strategies.

    Sustainability is ingrained in our business operations. Our vision for building a sustainable business is guided by six guiding principles: ensure the safety of our employees and communities; maintain high standards for environmental stewardship; foster a positive impact in the communities in which we live and work; contribute to a sustained local economy by creating jobs and growing business; bring our differentiated expertise to every quality project we deliver; and maintain an inclusive, fair, and welcoming work environment. We regularly engage our various stakeholder groups to ensure our business processes align with their most pressing concerns while supporting our core business strategy. We track and measure an established set of sustainability performance metrics to help us understand and report our overarching impact.

    An overview of our sustainability efforts and associated metrics can be found in the Company’s sustainability report, which is published annually and available at www.centuri.com/sustainability. The information on our website and sustainability report does not constitute a part of, and is not incorporated by reference into, this Proxy Statement or any other document we file with (or furnish to) the SEC, whether made before or after the date of this Proxy Statement.

    Audit Committee
    Meetings Held in 2025: 9
    Separately designated standing committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. The committee meets periodically with management to consider, among other things, the adequacy of the Company’s internal control and financial reporting. The committee also discusses these matters with the Company’s independent registered public accounting firm, internal auditors and Company financial personnel. The Board has determined that directors Julie A. Dill, Andrew W. Evans and Christopher A. Krummel each qualifies as an “audit committee financial expert,” as the term is defined in Item 407(d)(5)(ii) of Regulation S-K under the Exchange Act.
    Compensation Committee
    Meetings Held in 2025: 4
    Responsible for determining Chief Executive Officer compensation and making recommendations to the Board annually on such matters as executive compensation and benefits and director compensation and benefits. The committee’s responsibilities, as outlined in its charter, can be delegated to subcommittees made up of committee members. The committee receives recommendations from management on the amount and form of executive and director compensation, and the committee has the ability to directly employ consultants to assess the executive compensation program and director compensation. The committee is also responsible for the “Compensation Committee Report” and related disclosures contained in this Proxy Statement. Administration of the Company’s clawback policy is the responsibility of the Compensation Committee.
    Nominating and Corporate Governance Committee
    Meetings Held in 2025: 4
    Responsible for making recommendations to the Board regarding nominees to be proposed for election as directors; evaluating the Board’s size, composition and classification; developing criteria for the selection of directors; and overseeing our environmental, social and governance (“ESG”) initiatives. The committee will consider director candidates suggested by stockholders. The process for selecting directors is addressed in more detail below under the caption “Selection of Directors.” The committee is responsible for developing and recommending to the Board corporate governance guidelines, reviewing such guidelines annually and implementing and monitoring compliance with the Company’s Code of Business Conduct and Ethics.
    The charters for the Audit, Compensation and Nominating and Corporate Governance Committees, the Company’s Corporate Governance Guidelines and the Company’s Code of Business Conduct and Ethics that applies to all employees, officers and directors are available on the Company’s website at www.centuri.com. Any amendments to the Company’s Code of Business Conduct and Ethics or waivers of it for our directors and executive officers will be posted on our website at www.centuri.com promptly to the extent required by law. The information on our website is not part of this Proxy Statement and is not incorporated into any of our filings made with the SEC. Print versions of these documents are available to stockholders upon request directed to the Corporate Secretary, Centuri Holdings, Inc., 19820 North 7th Avenue, Suite 120, Phoenix, Arizona 85027.

    Insider Trading Policy
    The Board has adopted insider trading policies and procedures governing the purchase, sale and/or any other disposition of the Company’s securities and material non-public information that are reasonably designed to promote compliance with insider trading laws, rules, regulations, and applicable NYSE standards. Our Insider Trading Policy applies to the Company’s directors, officers, employees and to their immediate family members, as well as certain of the Company’s contractors and consultants who have access to material nonpublic information. Our Insider Trading Policy has been filed as Exhibit 19.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 28, 2025.

    Selection of Directors
    We believe the Board should be comprised of individuals with varied backgrounds, who possess certain core competencies, some of which may include broad experience in business, finance or administration and familiarity with national and international business matters. Additional factors that will be considered in the selection process include the following:     
    •personal and professional integrity and character;         
    •prominence and reputation in his or her profession;
    •skills, knowledge and expertise (including business or other relevant experience) that in aggregate are useful and appropriate in overseeing and providing strategic direction with respect to our business and serving the long-term interests of our stockholders;
    •the capacity and desire to represent the interests of the stockholders as a whole; and
    •availability to devote sufficient time to the affairs of the Company.

    The Nominating and Corporate Governance Committee takes many factors into consideration as it selects the director nominees for approval by the Board. The Nominating and Corporate Governance Committee does not assign a specific weight to any one factor. The Board Skills and Composition Matrix below enumerates certain qualifications and factors regarding the Board’s nominees.

    The Nominating and Corporate Governance Committee has an ongoing program for identifying and evaluating potential director candidates. In the director candidate search process, the Nominating and Corporate Governance Committee uses its network of contacts to compile a list of potential candidates, and may also engage a professional search firm when appropriate. In addition, the Nominating and Corporate Governance Committee may solicit suggestions from incumbent directors, management or others when seeking director candidates. As candidates are identified, their qualifications are reviewed in light of the selection criteria outlined above. Whether any of such candidates are selected depends upon the current Board composition, the dynamics of the Board and the ongoing requirements of the Company (see “Board Evaluation and Director Succession Planning” below).

    In its discretion, the Nominating and Corporate Governance Committee will also consider recommendations of qualified nominees by stockholders by evaluating the same factors as described above.

    In addition to the process described above, our bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director, the stockholder must meet certain deadlines established by our bylaws and provide certain information required by our bylaws. For a description of the process for nominating directors in accordance with our bylaws, see “Stockholder Proposals for the Next Annual Meeting.”

    Board Evaluation and Director Succession Planning
    In accordance with the Company’s Corporate Governance Guidelines, the Board and its committees conduct annual self-evaluations of their performance to determine whether they are functioning effectively. The Nominating and Corporate Governance Committee oversees the annual evaluation of the Board’s performance, whereas each committee reports annually to the Board with an assessment of its performance. As part of the Board’s self-evaluation process, the directors consider various topics relating to Board composition, structure, effectiveness and responsibilities, as well as the overall mix of director skills, experience and backgrounds. The Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee self-evaluation processes are led by their respective committee chairs, as provided in the committee charters. Each committee performance evaluation includes a review of the committee charter to consider the necessity and appropriateness of changes.

    We expect that annual evaluations are likely to be a key component of the director nomination process and director succession planning. In planning for succession, the Nominating and Corporate Governance Committee and the Board consider the results of Board evaluations, as well as other appropriate information, including the overall mix of tenure and experience of the Board, the types of skills and experience desirable for future Board members and the needs of the Board and its committees at the time.

    Given the importance of recruiting qualified, independent individuals to serve as directors of the Company, the Board believes that it is prudent to conduct a dedicated search for potential director candidates in order to preserve the high quality of the Board and maintain its breadth of experience. Ms. Mariucci is the current chairperson of the Nominating and Corporate Governance Committee, which is responsible to lead the execution of our succession plans over the course of the next several years.

    Stockholder Engagement
    The Company believes that maintaining an active dialogue with our stockholders is of utmost importance in delivering sustainable, long-term value for our stockholders. Since the closing of Centuri’s initial public offering on April 22, 2024 (the “Centuri IPO”), the Company’s Investor Relations group has engaged with stockholders on a variety of topics to ensure the Company addresses questions and concerns, seeks input, and provides perspective on the Company’s policies and practices. Feedback gathered from this outreach is regularly reviewed and considered by the Board and is reflected in adjustments and enhancements made to the Company’s policy and practices, particularly with regard to executive compensation and Company subsidiary structure. The Company also frequently participates in industry related investor conferences and engages with wall street research analysts. The Company highly values the time spent with stockholders and actively seeks to increase transparency and to better understand stockholder views on key issues.

    Director Attendance at Annual Meetings
    We strongly support and encourage each member of the Board to attend our annual meeting of stockholders. We expect all of the nine director nominees to attend the Annual Meeting.

    Communications with Directors
    Anyone who would like to communicate with, or otherwise make his or her concerns known directly to the chairperson of any of the Audit, Nominating and Corporate Governance, and Compensation Committees, or to the Independent Directors as a group, may do so by addressing such communications or concerns to the Corporate Secretary of the Company, Centuri Holdings, Inc., 19820 North 7th Avenue, Suite 120, Phoenix, Arizona 85027, who will forward such communications to the appropriate party.

    CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS
    Policies and Procedures with Respect to Related Person Transactions
    The Company has a written policy detailing the procedures for the review, approval or ratification of any transaction involving more than $120,000 between the Company and any director or officer of the Company, any director nominee, any person who is the beneficial owner of more than 5% of the Common Stock, or any immediate family members of the foregoing (each, a “Related Person”), who had a direct or indirect material interest (the “Related Person Transactions”) in said transaction. In accordance with the written policy and pursuant to the Corporate Governance Guidelines, any potential Related Person Transaction, including transactions that involve less than $120,000, must first be reported to the Chief Legal & Administrative Officer of the Company and reviewed by the Audit Committee. Each of the agreements between us and Southwest Gas Holdings that was entered into prior to the completion of the Centuri IPO was not subject to the terms of such policy. However, to the extent any such transaction is materially amended, then the Audit Committee is required to review and approve such transaction.

    The Audit Committee will approve and ratify the Related Person Transaction only if the committee determines that the transaction is not inconsistent with the best interests of the Company and may, in its discretion, impose any conditions it deems appropriate on the Company or the Related Person in connection with the Related Person Transaction.

    Each transaction with a related person is unique and must be assessed on a case-by-case basis. In determining whether or not to approve, the Audit Committee considers all of the relevant facts and circumstances available to the committee, including without limitation:
    •The Related Person’s interest in the proposed transaction;
    •The approximate dollar value of the amount involved in the proposed transaction;
    •The approximate dollar value of the amount of the Related Person’s interest in the proposed transaction without regard to the amount of any profit or loss;
    •Whether the transaction is proposed to be, or was, undertaken in the ordinary course of business of the Company;
    •Whether the transaction is proposed to be, or was, entered into on terms no less favorable to the Company than terms that could have been reached with an unrelated third party;
    •The purpose of, and the potential benefits to the Company from, the transaction;
    •The impact on a director’s independence in the event the Related Person is a director, an immediate family member of a director or an entity in which a director is a partner, stockholder or executive officer; and
    •Any other information regarding the transaction or the Related Person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

    Certain Relationships and Related Person Transactions
    We describe below transactions and series of similar transactions, since the beginning of our last full fiscal year or currently proposed, to which we were a party or will be a party, in which:
    •the amounts involved exceeded or will exceed $120,000; and
    •any of our directors, executive officers or beneficial holders of more than 5% of any class of our capital stock had or will have a direct or indirect material interest.

    Other than as described below, there have not been, nor are there any currently proposed, transactions or series of similar transactions meeting these criteria to which we have been or will be a party other than compensation arrangements, which are described under “Executive Compensation” and “Director Compensation” below.

    Relationship with Southwest Gas Holdings

    Relationships with Southwest Gas Holdings and Southwest Gas Corporation

    Prior to the completion of the Centuri IPO, through a series of steps, Southwest Gas Holdings transferred to us substantially all of the assets and liabilities of Centuri Group’s business (the “Separation”). Immediately following the completion of the Centuri IPO, Southwest Gas Holdings beneficially owned approximately 81.0% of our outstanding shares of Common Stock. Southwest Gas Holdings fully divested all of its remaining ownership interest in the Company on September 5, 2025, and therefore relinquished all the governance rights originally afforded to it under the Separation Agreement it had with the Company, dated April 11, 2024 (the “Separation Agreement”). We continue to perform various construction services for Southwest Gas Corporation, a wholly owned subsidiary of Southwest Gas Holdings.

    2026 Proxy Statement

    Table of Contents
    In addition, Ms. Haller, a member of our Board, has an indirect interest in transactions involving Southwest Gas Holdings due to her positions as the President, Chief Executive Officer of Southwest Gas Holdings. Ms. Haller has announced that she will be retiring from her positions as the President and Chief Executive Officer of Southwest Gas Holdings and Chief Executive Officer of Southwest Gas Corporation, effective May 8, 2026, and from her position as director of Southwest Gas Holdings and Southwest Gas Corporation, effective as of the conclusion of Southwest Gas Holdings' annual meeting of stockholders on May 7, 2026, and that she plans to serve as an advisor to Southwest Gas Holdings following her resignation through December 31, 2026.

    Approximately $97.6 million of our revenue for the fiscal year ended December 28, 2025 (“fiscal 2025”) was related to contracts with Southwest Gas Corporation. We recognized gross profit related to the Southwest Gas Corporation revenue of $6.6 million in fiscal 2025. Approximately $11.9 million of our accounts receivable, $0.7 million of contract assets and no significant contract liabilities were related to contracts with Southwest Gas Corporation as of December 28, 2025.

    Additionally, certain costs incurred by Southwest Gas Holdings have been allocated to us pursuant to the Separation Agreement, which are settled in cash during the normal course of operations. For fiscal 2025, we recorded a de minimis value of such allocated costs.

    Tax Matters Agreement

    On April 11, 2024, in connection with the Separation and prior to the completion of the Centuri IPO, we entered into a Tax Matters Agreement with Southwest Gas Holdings that governs the parties’ respective rights, responsibilities and obligations in connection with the Separation with respect to taxes, including taxes arising in the ordinary course of business, and taxes, if any, incurred as a result of the failure of a tax-free distribution to Southwest Gas Holdings and its stockholders (the “Distribution”) (and certain related transactions), if effected, to qualify for tax-free treatment for U.S. federal income tax purposes (the “Tax Matters Agreement”).

    The Tax Matters Agreement generally requires us to be responsible and to indemnify Southwest Gas Holdings for all taxes relating to the utility infrastructure services business for all periods.

    In addition, the Tax Matters Agreement requires us to indemnify Southwest Gas Holdings for any taxes (and certain related losses) resulting from the failure of the Distribution and related transactions to qualify for their intended tax treatment, where such taxes result from breaches of covenants and representations we make in the Tax Matters Agreement or certain prohibited actions we take after the Distribution that give rise to these taxes. Southwest Gas Holdings has the exclusive right to control the conduct of any audit or contest relating to Distribution-related taxes, but we have notification, information and comment rights regarding any such audit or contest to the extent that we could be liable for any resulting taxes under the Tax Matters Agreement.

    The Tax Matters Agreement imposes certain restrictions on us and our subsidiaries (including restrictions on share issuances, redemptions, mergers or other business combinations, sales of assets and similar transactions) that are intended to preserve the ability of Southwest Gas Holdings to effectuate the Distribution and related transactions in a tax-free manner. In the event that the Distribution and/or related transactions fail to qualify for their intended tax treatment due to any prohibited action or omission by us, our stockholders or any of our subsidiaries, we would generally be required to indemnify Southwest Gas Holdings for the resulting taxes under the Tax Matters Agreement. For example, if we or our stockholders were to engage in transactions that resulted in a 50% or greater change (by vote or value) in the ownership of our stock during the four-year period beginning on the date that is two years before the date of the Distribution and ending on the date that is two years after the Distribution, the Distribution may be taxable to Southwest Gas Holdings, and we generally would be required to indemnify Southwest Gas Holdings for the tax on such gain and related expenses.

    Under the Tax Matters Agreement, the restrictions described in the preceding paragraph generally will apply for two years following the Distribution date, if the Distribution is effected (or, if earlier, the date that Southwest Gas Holdings determines to no longer pursue the Distribution or determines it is no longer possible to implement the Distribution on a basis that is tax-free to Southwest Gas Holdings and its stockholders).

    Unutilized Tax Assets Settlement Agreement

    On February 24, 2025, we entered into an Unutilized Tax Assets Settlement Agreement with Southwest Gas Holdings (the “Tax Assets Agreement”). The Tax Assets Agreement addresses our arrangements with Southwest Gas Holdings with respect to
    Logo.jpg
    15
    2026 Proxy Statement

    Table of Contents
    certain unutilized tax assets (the “Tax Assets”) that we have retained following the deconsolidation from Southwest Gas Holdings for purposes of U.S. federal and relevant state income tax laws. Under the terms of the Tax Assets Agreement, the balance of the Tax Assets at tax deconsolidation, subject to true-up, and including the impact of any payments or deemed payments made by Southwest Gas Holdings in respect of the Tax Assets were treated as deemed capital contributions and recorded within additional paid-in capital, which resulted in an increase in Southwest Gas Holdings’ basis in its ownership of our Common Stock. The deemed capital contributions did not require any cash payment from us and had no impact on our liquidity or financial condition. As Southwest Gas Holdings no longer owns shares of our Common Stock, the Company will no longer be included in Southwest Gas Holdings’ U.S. federal and state income tax returns. However, Tax Assets allocated to the Company remain subject to true-up until after Southwest Gas Holdings’ U.S. federal and state tax returns for tax year 2025 are filed, with any changes after deconsolidation impacting the consolidated statements of operations.

    Relationship with Entities Affiliated with Carl C. Icahn

    Private Placement with the Company

    On November 11, 2025, we entered into a common stock purchase agreement (the “Private Placement Agreement”) with Icahn Partners LP and Icahn Partners Master Fund LP, investment entities affiliated with Carl C. Icahn (collectively, the “Icahn Investors”), pursuant to which we issued and sold approximately $75 million of shares of our Common Stock (the “Centuri Private Placement Shares”) to the Icahn Investors in a transaction exempt from registration under the Securities Act (the “Centuri Private Placement”) at a price per share and on terms as offered to the public in a concurrent underwriter offering of our Common Stock. The Private Placement Agreement contains customary representations, warranties, covenants, and other obligations of the parties. The representations, warranties and covenants contained in the Private Placement Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.

    Registration Rights

    In connection with the Centuri Private Placement and certain other private placements by Southwest Gas Holdings (collectively, the “Private Placements”) of shares of our Common Stock (such shares of Common Stock, together with the Centuri Private Placement Shares, the “Private Placement Shares”) to the Icahn Investors in transactions exempt from registration under the Securities Act, we granted the Icahn Investors certain resale registration rights with respect to the Private Placement Shares, as set forth in three separate Registration Rights Letter Agreements by and among the Company and the Icahn Investors (collectively, the “Icahn Registration Rights Agreements”). Pursuant to the Icahn Registration Rights Agreements, subject to certain circumstances, the Company agreed to register the resale of the Private Placement Shares no later than the 181st day following the date of closing of each Private Placement. The Icahn Investors will be permitted to make sales of Common Stock from time to time under a resale registration statement but do not have rights to demand underwritten offerings or “piggyback” registration.

    Riggs Distler Management Interest in Drum

    In November 2021, certain members of the management team of our subsidiary, Riggs Distler, acquired a 1.42% interest in Drum Parent LLC, the former parent company of Riggs Distler. Effective January 2027 and each calendar year thereafter or upon the occurrence of certain trigger events, we have the right, but not the obligation, to purchase all of the interest held by the noncontrolling party at fair value. If we do not exercise our rights in accordance with this timeline, or upon the occurrence of certain other triggering events, the noncontrolling party has the ability, but not the obligation, to exit their investment retained by requiring us to purchase all of their outstanding interest. The outstanding noncontrolling interest is not subject to minimum purchase provisions and, following the eligibility date for the election, they do not expire. The redemption price represents the fair value of the ownership interest to be redeemed on the redemption date under the terms of the agreement. A portion of the redeemable noncontrolling interest acquired was funded through promissory notes made to noncontrolling interest holders bearing interest at the prime rate plus 2%. The promissory notes are payable by the noncontrolling interest holders upon certain triggering events including, but not limited to, termination of employment or the redemption of any interest under the agreement.

    The remaining noncontrolling interest in Drum outstanding as of December 28, 2025 was 0.80%.

    Executive Summary
    Incentive Compensation Structure
    Centuri’s compensation program is designed to attract, retain, and motivate leaders who deliver long-term value for stockholders. The program balances competitive pay opportunities with rigorous performance expectations, emphasizing financial discipline, safety excellence, operational performance and strategic value creation. It also (i) is a competitive program relative to the market and our peers, (ii) aligns with market best governance practices, (iii) supports robust pay-for-performance alignment, and (iv) provides the appropriate linkage between executive compensation and the Company’s long-term business strategy.

    The 2025 executive compensation program provides for performance-based annual cash and long-term equity incentive awards, as well as time-based long-term equity awards. The performance-based incentive awards are conditioned upon the achievement of performance results measured against rigorous pre-set targets. Under this incentive structure, a greater portion of our executives’ total compensation is at-risk and variable based on performance relative to metrics that are directly aligned with our short- and long-term performance, customer interests and stockholder returns.

    Commitment to Best Practices
    We believe in the importance of aligning the financial interests of the Company’s executives with those of stockholders and maintaining executive compensation policies that are consistent with robust corporate and compensation program governance. The Compensation Committee reviews our executive compensation program annually to ensure it maintains its competitiveness with the market and supports our short- and long-term growth strategies. Key policies governing our executive compensation program include:
    •The Compensation Committee engages an independent compensation consultant, Meridian Compensation Partners (“Meridian”);
    •Double-trigger change in control arrangements which do not provide for excise tax gross-ups or severance amounts greater than three times base salary, excluding equity and incentive compensation, welfare benefits, retirement benefits and outplacement services;
    •Formal executive stock ownership and post-vesting holding requirements to reinforce long-term alignment with stockholders;
    •No tax gross-up on benefits, change in control payments, or perquisites;
    •No dividends paid on unvested stock-based awards until the underlying awards have vested;
    •Clawback policy applicable to annual and long-term cash- and equity-based incentive compensation; and
    •Benchmark all elements of executive officer compensation and program design against an appropriate peer group.

    Compensation Program Objectives, Key Considerations and Principles
    Philosophy and Objectives
    Centuri’s executive compensation program is designed to support the Company’s short- and long‑term strategies, reinforce a performance‑driven culture, and align the interests of executives with stockholders. The program is structured to be market‑competitive, performance‑based, and governed by strong compensation and governance practices. The Compensation Committee has structured Centuri’s executive compensation program covering NEOs to include the following key governance and design practices:

    •Attract, retain, and motivate high-caliber leadership by delivering competitive and sound total rewards that reflect market benchmarking and internal equity.
    •Provide a balanced mix of pay components and incentives through a well‑balanced compensation program that integrates cash and equity elements and incorporates both annual and long‑term incentives to reinforce sustained performance and stockholder alignment.
    •Align pay with performance by emphasizing financial, operational, and strategic objectives and results through annual and long-term incentives. A significant portion of our NEOs’ total compensation is tied to the achievement of business objectives and creation of long-term stockholder value. This ensures NEO pay is aligned with business and share performance. While we emphasize “at- risk” pay tied to performance, we have designed the executive compensation program so that it does not encourage excessive risk-taking by management.
    •Promote long-term value creation and financial discipline, supported by a shift toward value-driving long-term incentive plan metrics such as return on net assets (“RONA”) and free cash flow to strengthen operational efficiency and sustainable growth.
    •Limited perquisites provided to NEOs and only to the extent they are reasonable and consistent with our compensation objectives of attracting and retaining superior executives for key positions.

    •Clawback Policy that complies with applicable legal and stock exchange listing requirements and that provides Centuri the authority to recover erroneously paid incentive compensation in connection with an accounting restatement.
    •Use of Meridian, an Independent Compensation Consultant who advises the Compensation Committee on the design and market competitiveness of our executive compensation program.

    Majority of Executive Compensation is Performance-Based
    The majority of each NEO’s target total direct compensation is composed of at-risk variable compensation. The percentage of at-risk pay depends upon the NEO’s position and the ability to influence outcomes, competitive market practice and risk mitigation considerations. The Company’s CEO 2025 at-risk pay was equal to 79% of his target total direct compensation opportunity. For the other NEOs, the average percentage of at-risk pay was equal to 74% of average target total direct compensation. The charts below set forth the 2025 target total direct compensation pay mix for our CEO and the other NEOs’ average target total direct compensation pay mix as well as the 2025 long-term incentive equity mix.

    Compensation Program Administration
    Role of the Compensation Committee
    The Compensation Committee oversees our executive compensation program and is responsible for reviewing and approving all executive compensation and benefit plans of the Company’s executive officers, including its NEOs. The Compensation Committee works closely with its independent compensation consultant and meets regularly throughout the year to review and discuss our compensation philosophy, compensation governance, composition of our peer group, incentive plan design and related corporate goals and objectives. In addition, the Compensation Committee reviews and approves the CEO’s target compensation (and each component of compensation) taking into account the CEO’s performance in relation to corporate goals and objectives, individual performance and peer group practices. Based on the recommendations provided by the CEO, the
    Logo.jpg
    30
    2026 Proxy Statement

    Table of Contents
    Compensation Committee also reviews and approves the salaries and incentive compensation for the other NEOs. The full description of the Compensation Committee’s authority and responsibilities is provided in the Compensation Committee Charter, which is available on the Company’s website at https://investor.centuri.com/governance/governance-documents/default.aspx.

    Role of Management
    When making decisions on executive compensation, the Compensation Committee considers input from management, including the NEOs. Management annually provides information to the Compensation Committee regarding market practices and pay levels of the various elements of direct compensation (including target awards for incentive compensation), as well as the thresholds, targets and maximums of the performance measures. Information is gathered from Company operating data, external independent surveys and publicly available compensation comparisons. Decisions regarding CEO compensation are made solely by the Compensation Committee meeting in executive session without the CEO or any other NEOs present. Decisions regarding the compensation of other NEOs are also made by the Compensation Committee, in consultation with the CEO, but without the other NEOs being present.

    Role of Independent Compensation Consultant
    Meridian served as the independent compensation consultant to the Compensation Committee during fiscal 2025. Meridian reports directly to the Compensation Committee and does not provide any services to the Company other than the Compensation Committee consulting services. While the independent compensation consultant is retained by and accountable to the Compensation Committee, it still works collaboratively with management to ensure the Compensation Committee receives accurate, complete, and timely information for decision making. Meridian’s engagement with the Compensation Committee as its independent compensation consultant included advice and counsel on executive and director compensation matters, analyses on prevailing market practices and information on pertinent regulatory mandates.

    Meridian did not receive fees from the Company for services other than the services listed above. For fiscal 2025, the Compensation Committee analyzed whether the work of Meridian or any other executive compensation adviser raised any conflicts of interest, taking into consideration all relevant factors, including those set forth in Rule 10C-1(b)(4)(i) through (vi) under the Exchange Act. The Compensation Committee determined, based on its analysis of all relevant factors, that no conflicts of interest were present.

    How We Determine Amounts Paid for Each Element of Compensation
    We operate in a competitive environment for talented executives; therefore, the Compensation Committee analyzes a variety of information as it seeks to identify competitive levels of compensation within the relevant markets in which we operate.

    Peer Group
    The companies in the compensation peer group for our NEOs were selected because they represent those publicly-traded companies considered by the Compensation Committee to be the most comparable to the Company in terms of revenue, market capitalization, business operations, operational complexity and overall financial performance. To maintain a meaningful comparison, the Compensation Committee reviews the peer group regularly for changes due to M&A activity or shifts in our peers’ business focus or operations. For setting 2025 executive compensation, the peer group was composed of the following 15 companies in the Construction and Engineering Services industries and other related industry classifications. The 2025 peer group consisted of:

    Ameresco, Inc.MasTec, Inc.
    APi Group CorporationMDU Resources Group, Inc.
    Arcosa, Inc.MYR Group Inc.
    Comfort Systems USA, Inc.NV5 Global, Inc.
    Construction Partners, Inc.Primoris Services Corporation
    Dycom Industries, Inc.Sterling Infrastructure, Inc.
    Granite Construction Inc.Tutor Perini Corporation
    IES Holdings, Inc.

    In April 2025, the Compensation Committee reviewed the peer group for purposes of setting 2026 executive compensation. Meridian recommended, and the Compensation Committee approved, the removal of MDU Resources Group, Inc., and the
    Logo.jpg
    31
    2026 Proxy Statement

    Table of Contents
    addition of Everus Construction Group, Inc. These changes were made to better align the peer group to the Company’s business operations following Everus Construction Group’s spinoff from MDU Resources.

    Compensation Review
    The Compensation Committee conducts a comprehensive annual review of compensation for each NEO to ensure pay levels remain aligned with Centuri’s compensation philosophy, market competitiveness, and performance expectations. This review incorporates independent benchmarking provided by Meridian. The competitive compensation benchmarking data included analyses of base salary, annual incentive targets and values, long-term incentive values, and total direct compensation, as disclosed in the proxy statements filed by companies in the 2025 peer group. Management and Meridian supply market data, internal equity considerations, and role‑specific details to inform the Compensation Committee’s evaluation. The Compensation Committee also assesses individual performance, changes in leadership scope, retention risks, and long‑term succession planning needs. Where compensation levels differ materially from market or where leadership scope has evolved, the Compensation Committee may adjust specific pay elements—such as salary, mix of long-term incentives, or short-term incentive targets—to maintain appropriate alignment. Recommendations for adjustments are reviewed in coordination with the CEO for all NEOs other than the CEO and incorporate Compensation Committee feedback prior to approval. In connection therewith, Meridian also reviews each NEO’s target total direct compensation and each element of compensation against the 50th percentile of the applicable peer group. Based on this review, the Compensation Committee determines whether each NEO’s target total direct compensation warrants adjustments to generally align with the relevant market benchmarks. Following the review, it was determined that Messrs. Izenstark, Connell and Wilcock required increases to more closely align with competitive market benchmarks in 2025.

    Stockholder Say-on Pay Advisory Votes
    At our most recent Annual Meeting of Stockholders on April 16, 2025, over 98% of the votes cast on our Say-on-Pay proposal were voted in favor of the proposal. The Compensation Committee believes that this affirms our stockholders’ support of our approach to executive compensation. Accordingly, the Compensation Committee did not implement any changes to our executive compensation program as a result of the advisory vote.

    Also at such Annual Meeting, our stockholders approved an annual Say-on-Pay frequency period and, based on such approval, we determined to conduct a Say-on-Pay vote each year. Pursuant to the “Say-on-Pay Proposal” included in this Proxy Statement, we are asking our stockholders to vote on an advisory basis to approve the compensation of our NEOs. The Compensation Committee values stockholder feedback on the Say-on-Pay advisory vote, and will carefully consider the outcome of the vote, along with input from our stockholder engagement efforts, when making future compensation decisions for our NEOs.

    Details of Compensation Program
    The Compensation Committee has designed our executive compensation program to reflect the nature of Centuri’s operational environment and the competitive dynamics of the construction utility infrastructure and engineering services industries. Consistent with prevailing market practices, our program is structured to remain responsive to changing industry conditions and to provide a comprehensive set of compensation opportunities. Central to this design is a rigorous emphasis on performance: both individual contributions and overall Company results materially influence each NEO’s annual compensation outcomes.

    Why We Pay Each Element
    The elements of executive compensation for the NEOs and the purpose for providing each element are described below:

    Base Salaries
    Salaries for the NEOs are established based on the scope of their responsibilities, taking into account competitive market compensation paid by the peer group for similar positions. The competitive market processes and data regarding the 50th percentile pay level of peer companies were used by the Compensation Committee to help ensure that salaries are reasonable, competitive and properly address position responsibilities. The market data on the range of salaries at the peer companies serves as a reference point and provides information on the range of competitive pay levels and current compensation practices in our industry. Salaries are reviewed annually and are subject to adjustment to maintain alignment with the market and to reflect changes in individual responsibilities, performance, and experience.

    In 2025, the Compensation Committee approved merit increases for our NEOs to reflect performance achievements, and to ensure market competitiveness to the new market from Centuri being spun off and becoming a standalone public company. The following table shows our NEOs’ 2024 annual base salaries, 2025 annual base salaries and the percentages of their base salary increases in 2025, if any:

    Annual Incentive Compensation 2025 Performance Metrics.
    For our 2025 annual incentive opportunity, the Compensation Committee adopted three financial performance metrics (Adjusted EBITDA, free cash flow, and growth backlog) and two safety goals (Days Away From Work, Restricted or Transferred (“DART”) and Total Recordable Incident Rate (“TRIR”)). The selected performance metrics remain unchanged from 2024, except for the addition of growth backlog.

    Adjusted EBITDA is a non-GAAP measure and is defined as earnings before interest, tax, depreciation and amortization. For purposes of 2025 compensation, Adjusted EBITDA includes adjustments for $9 million of certain non-recurring or non-operational expenses including Separation-related costs, other professional fees and acquisition costs (net of current year contributions from Connect Atlantic Utility Services Corporation (“Connect”), a Canadian company we acquired on November 18, 2025). Adjusted EBITDA for purposes of our 2025 compensation differs from the Adjusted EBITDA presented in our other filings with the SEC in two aspects: (i) stock-based compensation is not added back for compensation purposes, and (ii) contribution from Connect is excluded in the Adjusted EBITDA for compensation purposes but not otherwise. For NEOs, no awards are paid unless at least 50% of target Adjusted EBITDA is achieved, and all other metric achievements are capped at target if Adjusted EBITDA achievement is below 80% of target.

    Free cash flow is a non-GAAP measure and is defined as cash flow from operations minus net capital expenditures (including amounts not yet paid, but recognized in liabilities). For purposes of 2025 compensation, free cash flow was adjusted for certain non-recurring or non-operational expenses, including Separation-related costs, certain debt fees expensed as part of the Company’s refinancing of its existing credit facilities in July 2025, other professional fees, acquisition costs (net of current year contributions from Connect), and aged receivables related to a key customer whose significant business growth during the year slowed the processing and payment of our invoices. These adjustments totaled approximately $37 million in 2025.

    The Compensation Committee added growth backlog as a performance metric for our 2025 annual incentive program, which measures growth in the organization through expansion of new services for existing customers and engagement with new customers. The Compensation Committee also increased the weighting on Adjusted EBITDA to emphasize growth and profitability and to provide a comprehensive view of Company's financial metric conducive to growth goals.

    Both DART and TRIR were considered for 2025 compensation purposes as they measure incident frequency and workplace safety, and improvement from their respective fiscal 2024 levels was required in setting their respective performance goals.

Actual awards for each measure are determined as of year-end results by comparing Centuri’s performance to the threshold, target, and maximum levels adopted by the Compensation Committee for each performance measure. When threshold performance for any measure is achieved, the portion of the award with respect to that measure is earned. Award payouts can range from 50% (at threshold) to 200% (at maximum) of the assigned target incentive opportunity for each measure, based on where actual results fall in the range from threshold to target or from target to maximum. We determine actual payouts through linear interpolation.

    The thresholds, targets and maximums and actual results under the performance measures for fiscal 2025 are set forth below:

    (2)Amounts in this column are rounded to the tenth decimal place.

    No annual incentive awards are paid to NEOs unless 50% of target Adjusted EBITDA is achieved on a consolidated basis and all other metric achievements are capped at target if Adjusted EBITDA achievement is below 80% of target. In fiscal 2025, Adjusted EBITDA exceeded 80% of target on a consolidated basis, and achievements under the other performance measures aggregated for a payout of 130.7% of the target incentive award opportunity. The Adjusted EBITDA results were calculated by removing $9 million in costs associated with Separation-related costs, other professional fees and acquisition costs (net of current year contributions from Connect) from EBITDA. The free cash flow results were adjusted to remove $17 million in costs associated with Separation-related costs, certain debt fees expensed as part of the credit facility refinancing, other professional fees, and acquisition costs (net of current year contributions from Connect). The free cash flow results were also adjusted $20 million for aged receivables related to a key customer whose significant business growth during the year slowed the processing and payment of our invoices. The aggregated percentage payout is multiplied by the total incentive opportunity (expressed above as a percentage of base salary) to determine the overall dollar value of the incentive award.

    Messrs. Brown, Izenstark and Wilcock each received an annual incentive award equal to 130.7% of his target annual incentive. Mr. Connell was not eligible for an award due to his resignation. Each NEO’s performance was measured on a consolidated basis.

    The following table details the actual payouts associated with the fiscal 2025 annual incentive awards for the NEOs:

    2025 Long-Term Incentive Compensation
    Our long-term incentive compensation aligns the interests of our NEOs with those of our stockholders by rewarding the enhancement of stockholder value and motivating retention of our NEOs. In 2025, the Compensation Committee granted to each NEO a combination of 60% performance stock units (“PSU”s), which vest based on performance and continued employment, and 40% restricted stock units (“RSU”s), which vest ratably over three years based on continued employment. One-third of the PSUs are earned based on RONA and free cash flow during a one-year performance period that started on December 30, 2024 and ended on December 28, 2025. The remaining two-thirds of the PSUs are earned based on performance over a two-year performance period beginning on December 29, 2025 and ending on January 2, 2028. The goals for the two-

    year performance period were established by the Committee in early 2026. Any amount of the PSUs earned will vest at the end of the three-year period.

    Beginning with the 2026 award, the PSUs will include 3-year cumulative performance goals set at the beginning of the 3-year measurement period.

    In 2025, for the Company’s first annual equity grant cycle following its public listing, the Compensation Committee granted Messrs. Izenstark and Wilcock a one-time increase to their long-term incentive awards to help establish meaningful stock ownership, strengthen alignment with stockholders and promote retention. The increase was from 140% to 290% of base salary for Mr. Izenstark and 135% to 200% of base salary for Mr. Wilcock.

    The Compensation Committee set each NEO’s long-term incentive opportunity generally at the median of the peer group. The table below shows each NEO’s 2025 long-term incentive opportunity granted as RSUs and PSUs. The values in the table below differ from the values included for such awards in the “2025 Summary Compensation Table” and the “Grants of Plan-Based Awards (2025)” table because the aggregate grant date fair values of the awards included in those tables are computed in accordance with stock-based accounting rules. As a result, performance shares will be included in the tables over multiple years when the performance period goals are set for each year, and the restricted share unit values included in the tables for 2025 vary slightly from the accounting values.

    One-third of the 2025 PSUs were eligible to be earned based on achievement against RONA and free cash flow performance goals over the one-year performance cycle ended on December 28, 2025. The Compensation Committee selected RONA and free cash flow as the performance metrics for the 2025 PSUs as these metrics drive key behaviors around operational efficiency, profitability and long-term sustainability. By shifting the focus to profitability with the use of RONA from a focus on revenue generation, key behaviors related to asset optimization, cost management and capital investment decision making are rewarded, which leads to an improved bottom line relative to asset investments. Optimizing the use of assets leads to better management and efficient use of equipment, while cost management drives a focus on controlling spend, as reducing expenses can significantly improve the return on assets. Improving decisions on capital investments prompts business leaders to prioritize projects that enhance asset efficiency to generate higher returns. RONA encourages long-term strategic planning, aligning investment decisions with sustainable value creation. The Compensation Committee adopted a one-year performance period followed by a two-year performance period due to various factors influencing the longer-term performance of the Company, including timing of ownership changes and overall transition to a standalone public company.

    The Compensation Committee established threshold, target, and maximum performance levels for the metrics. The target performance level was based on the Company’s business plan and budgets, taking into account factors such as budgeted capital expenditures, expected growth within the markets that the Company serves, competitive factors from other service providers and other business considerations embedded in the Company’s annual business planning process. Actual amounts earned can range from 50% to 200% of the target opportunity based on the level of achievement of the goals for both metrics. No amount is earned if threshold performance is not achieved. Linear interpolation is used to compute the amount earned if the performance is between two designated levels.

    The 2025 RSUs will vest in equal installments over three years, with one-third vesting on February 25 of each of 2026, 2027 and 2028, respectively. Any 2025 PSUs earned by the end of the three-year total performance period will vest on February 25, 2028 or the day when the Compensation Committee certifies the performance results of the performance period, whichever is later.

    Return on Net Assets, or RONA, is defined as adjusted pre-tax income divided by property and equipment, plus net working capital (net working capital excludes cash, current portion of long-term debt, and tax related balances and was adjusted to remove aged receivables related to a key customer whose significant business growth during the year slowed the processing of and payment of our invoices). Pre-tax income was adjusted for Separation-related costs, loss on debt modification and extinguishment of the credit facility, other professional fees, and acquisition costs (net of current year contributions from Connect). These adjustments were approximately $18 million. Free cash flow is defined as cash flow from operations minus net capital expenditures (including amounts not yet paid, but recognized in liabilities). Free cash flow was adjusted for certain non-recurring or non-operational expenses including Separation-related costs, certain debt fees expensed as part of the credit facility refinancing, other professional fees, acquisition costs (net of current year contributions from Connect), and aged receivables related to a key customer whose significant business growth during the year slowed the processing and payment of our invoices. These adjustments were approximately $37 million in 2025.

    2023-2024 Long-Term Incentive Compensation
    In fiscal 2023, Messrs. Connell and Wilcock received RSU grants relating to Southwest Gas Holdings common shares (“Southwest RSUs”) and PSU grants relating to Southwest Gas Holdings common shares (“Southwest PSUs”), and Mr. Izenstark received a time-based long-term cash award and a special time-based RSU grant relating to Southwest Gas Holdings common shares. In fiscal 2024, Messrs. Izenstark, Connell and Wilcock received a performance-based long-term cash award with a one-year performance period (the “2024 Cash Award”) and a special time-based RSU grant in connection with the successful initial public offering of the Company, Mr. Brown received a time-based RSU grant in connection with his hiring relating to shares of Common Stock, and Mr. Connell received a special retention time-based RSU grant relating to shares of Common Stock. Regarding the 2024 Cash Award, the Company did not achieve threshold performance over the one-year performance period ended on December 31, 2024, and no cash awards were earned at the conclusion of that performance cycle as a result. See “Outstanding Equity Awards at Fiscal Year-End 2025” and “Stock Vested During 2025” for additional information on shares granted in prior years.

    Perquisites
    In addition to base salary and performance‑based incentive opportunities, each NEO receives a limited set of perquisites and benefits designed to support market competitiveness and align with Centuri’s compensation philosophy. The Company maintains a nonqualified deferred compensation plan that allows the NEOs and other eligible participants to voluntarily defer eligible compensation, providing an additional mechanism for long‑term financial planning. These supplemental programs are intentionally limited in scope, regularly benchmarked against peer practices, and reviewed by the Compensation Committee to ensure they remain reasonable, are aligned with governance expectations, and support Centuri’s objective to attract and retain highly qualified executive leadership. The Company provides certain perquisites to each NEO, which the Compensation Committee believes are reasonable and consistent with the objective of attracting, retaining, and motivating high-performing senior leaders. The NEOs are eligible to receive company paid annual physical examinations and life insurance, and reimbursement annually for financial planning, estate planning and tax preparation. Any social club memberships and car allowances were phased out in 2025.

    Retirement Benefits
    The Company maintains two plans which provide retirement benefits for the NEOs: a 401(k) plan and a nonqualified deferred compensation plan, the Executive Deferred Compensation Plan (the “EDCP”).

    Logo.jpg

    2026 Proxy Statement

    Table of Contents
    •Centuri 401(k) Plan. NEOs receive matching contributions from Centuri to their accounts in the Centuri 401(k) plan, consistent with all other employees participating in the plan. The Company matches 100% of pre-tax contributions up to the first 3% of base salary and 50% on the next 4% of base salary. All matching contributions are immediately vested subject to certain limits as determined by law.
    •EDCP. Under the EDCP, certain employees, including the NEOs, are permitted to voluntarily defer receipt of up to 80% of base salary and up to 80% of other cash compensation. Employer matching contributions under the EDCP are equal to the first 5% of the salary compensation deferred by the employee under the plan. Matching contributions vest immediately. Participants may allocate deferred cash amounts among (i) a group of notional accounts that mirror the gains and/or losses of various investment alternatives that do not provide for above-market or preferential earnings, and (ii) an account with returns based on Centuri’s financial performance (the “LTCIP Fund”). Each NEO was required to invest at least 25% of their annual incentive compensation in the LTCIP Fund until the NEO met the established investment requirement – two times base salary for Centuri’s Chief Executive Officer and one times base salary for the other NEOs. LTCIP Fund investments grow or depreciate based on Centuri’s company growth rate. The maximum annual loss of the LTCIP Fund is negative 5% and the maximum annual gain is 20%. The LTCIP Fund was phased out in 2024 and funds were subsequently transferred to a money market account.

    Executive Agreements 
    Centuri has entered into an employment agreement with each of the NEOs (collectively, the “Employment Agreements”). The terms of the Employment Agreements, other than compensation and severance levels, are substantially consistent with one another. The Employment Agreements provide for specified levels of severance payments and benefits upon certain employment termination events both in the absence of and following certain change in control events. The Employment Agreements also contain non-competition, non-solicitation and other restrictive covenants. In approving the Employment Agreements, Centuri considered the aggregate potential obligations under the agreements, as well as the benefits of securing non-competition, non-solicitation and other restrictive covenants included in the agreements. The Employment Agreements do not contain excise tax gross-up provisions and, instead, employ a “best net” approach under which payments and benefits are either reduced to avoid the excise tax on excess parachute payments or not reduced, in which case the executive is responsible for any excise tax, depending on which approach would result in the greatest after-tax amount being retained. See the “Potential Payments Upon Termination or Change in Control” section below for a more detailed discussion of the severance payments and benefits provided under the Employment Agreements.

    Option Grant Practices
    Stock options have not been a part of our executive compensation program. We therefore (i) do not grant, and have not granted, stock options in anticipation of the release of material nonpublic information, (ii) do not time, and have not timed, the release of material nonpublic information based on stock option grant dates or for the purpose of affecting the value of executive compensation and, (iii) do not take, and have not taken, material nonpublic information into account when determining the timing and terms of stock options. As stock options are not an element of employee compensation, we do not have a formal policy with respect to the timing of stock option grants, and we did not grant stock options or stock appreciation rights in 2025.

    Executive Stock Ownership Requirement
    We place a premium on aligning the interests of our executives with those of our stockholders. Under our Stock Ownership and Stock Retention Policy ("Stock Ownership Policy"), our CEO is required to accumulate at least five times the value of his annual base salary in Common Stock, while our Presidents, Executive Vice Presidents and other senior leadership team members are required to accumulate at least two times the value of his or her annual base salary in Common Stock. In addition, each such officer must hold 50% of the net shares acquired from the Company until the total number of shares held by such officer equals or exceeds the minimum share ownership requirement. All of our NEOs are currently in compliance or working towards compliance with these ownership requirements.

    Anti-Hedging and Anti-Pledging Policy
    Pursuant to our Insider Trading Policy, our directors and officers are prohibited from engaging in hedging or monetization transactions involving our securities, including transactions using financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds, that are designed to offset or limit the risks and rewards of ownership. In addition, our Insider Trading Policy prohibits directors and officers from holding our securities in margin accounts or otherwise pledging our securities as collateral for a loan.

    Clawback Policy
    On March 21, 2024, the Board approved a clawback policy for executive officers, in compliance with NYSE rules and SEC regulations. The Company’s clawback policy allows the Company to recoup the value of any erroneously awarded incentive compensation granted, earned, or vested based wholly or partly on the attainment of performance conditions containing financial reporting measures, in the event that the Company is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirements under securities laws. The clawback policy covers any erroneously awarded incentive compensation received during the three completed fiscal years preceding the date on which the Company is required to prepare such accounting restatement and covers, among other types of incentive compensation, annual cash incentives and long-term incentive awards. Administration of the Company’s clawback policies is the responsibility of the Centuri Compensation Committee.

    (1)Amounts shown in this column include any amounts deferred by the NEOs into 401(k) and nonqualified deferred compensation plans.
    (2)Amounts shown in this column represent the aggregate grant date fair value of awards of Southwest PSUs granted in 2023, Southwest RSUs granted in 2023 and 2024, RSUs relating to Common Stock granted in 2024 and 2025 and PSUs granted in 2025. The 2023 amounts for Mr. Wilcock include the grant date fair value of Southwest RSUs that were scheduled to cliff vest on January 1, 2026, assuming all vesting requirements were met, and the grant date fair value of Southwest PSUs that were scheduled to vest on January 1, 2026, subject to the achievement of performance conditions and other vesting requirements; the vesting of these Southwest RSUs accelerated on December 5, 2025 in connection with the Separation. The Southwest PSUs granted in fiscal 2023 had a one-year performance cycle and vest three years after they were granted, based upon the achievement of Centuri free cash flow goal during 2023, and vest three years after they were granted. The Southwest PSUs were achieved at 149.8% of the target value. In 2023, for Mr. Izenstark, the amount represents the grant date fair value of his special Southwest RSUs that vest over three years, with 40%, 30% and 30% scheduled to vest on each of December 31, 2024, December 31, 2025 and December 31, 2026, respectively, assuming all vesting requirements were met; the vesting of the second and third installments of these RSUs accelerated on December 5, 2025 in connection with the Separation. In 2024, for Mr. Brown, the amount represents the grant date fair value of his time-based RSUs that vest over three years, with 40%, 30% and 30% vesting on each of December 3, 2025, December 3, 2026 and December 3, 2027, respectively, assuming all vesting requirements are met. In 2024, for Messrs. Izenstark and Wilcock, the amounts include the grant date fair value of time-based RSUs with one-year cliff vesting on May 12, 2025, assuming all vesting requirements were met. In 2024, for Mr. Connell, the amount includes the grant date fair value of time-based RSUs with one-year cliff vesting on May 12, 2025, assuming all vesting requirements were met, and the grant date fair value of time-based RSUs with eighteen-month cliff vesting on January 30, 2026, assuming all vesting requirements were met. In 2025, for Messrs. Brown, Izenstark, Connell and Wilcock, the amounts include the grant date fair value of time-based RSUs that vest over three years, with one-third vesting on each of February 25, 2026, February 25, 2027 and February 25, 2028 assuming all vesting requirements are met, and the grant date fair value of PSUs that vest on February 25, 2028, subject to the achievement of performance conditions and other vesting requirements. In each case, the amounts were determined in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718 based on the Common Stock share price on the date of grant. The value ultimately realized by the NEO upon actual vesting of the awards may or may not be equal to this determined value. The assumptions used to calculate these amounts with respect to the time-based RSUs relating to shares of Common Stock are the closing price on the grant date multiplied by the units granted. The assumptions used to calculate these amounts with respect to Southwest PSUs and Southwest RSUs are included in “Note 9 - Share-Based Compensation” included in the footnotes to the consolidated financial statements in Southwest Gas’s 2024 Annual Report on Form 10-K. However, as required, the amounts shown in this column exclude the impact of estimated forfeitures. Values of Southwest PSUs were calculated based on the probable outcome of the performance conditions as of the grant date, which was determined to equal the target level of performance. The maximum potential value of the Southwest PSUs for Mr. Wilcock, assuming the highest level of performance achievement, is $287,852. The maximum potential value of the PSUs granted in 2025, assuming the highest level of performance achievement, is as follows: for Mr. Brown, $1,123,269; for Mr. Izenstark, $576,020; for Mr. Connell, $221,416; and for Mr. Wilcock, $378,492. Upon settlement, Southwest Gas shares of common stock are issued for each earned Southwest PSU. Award agreements for Southwest PSUs and Southwest RSUs give the right to receive dividend equivalent payments as and when dividends are paid on Southwest Gas shares of common stock. The time-based RSUs relating to shares of Common Stock give the right to receive dividend equivalent payments as and when dividends are paid on Common Stock. Such dividends are reallocated into additional equity awards of the same type and with the same vesting schedule as the original award, as applicable.
    (3)For 2025, amounts shown in this column represent the annual incentive cash awards paid in 2026 for services performed in 2025. For Messrs. Brown, Izenstark and Wilcock, the amount of the 2025 annual incentive cash award earned was $1,509,169, $500,378 and $476,760, respectively. For 2024, amounts shown in this column represent the annual incentive cash awards paid in 2025 for services performed in 2024. For Messrs. Izenstark, Connell and

    (6)The aggregate amount of the disclosed perquisites and personal benefits for each NEO is based on the incremental cost to Centuri. In 2025, the aggregate amount of perquisites and personal benefits for Messrs. Brown, Izenstark and Wilcock was less than $10,000 each. Additionally, on occasion, Mr. Brown has had family members or personal guests accompany him on the chartered aircraft utilized by the Company when traveling on business, at no incremental cost to the Company. The perquisites and personal benefits for Mr. Connell include car allowance, club dues, annual physical and life insurance.
    (7)For 2025, for Mr. Izenstark, amounts shown in this column represent one-third of time-based long-term incentive cash awards for the three-year period beginning in 2023 and paid in 2026 in the value of $60,900. For 2024, for Mr. Izenstark, amounts shown in this column represent one-third of time-based long-term incentive cash awards for the three-year period beginning in 2023 and paid in 2026 and one-third of time-based long-term incentive cash awards for the three-year period beginning in 2022 and paid in 2025 in the value of $60,900 and $33,833, respectively. For 2023, for Mr. Izenstark, amounts shown in this column represent one-third of time-based long-term incentive cash awards for the three-year period beginning in 2023 and paid in 2026, one-third of time-based long-term incentive cash awards for the three-year period beginning in 2022 and paid in 2025, a discretionary bonus for filling the Interim Chief Financial Officer role and a discretionary bonus in connection with the Linetec earn-up allocation in the value of $60,900, $33,833, $50,000 and $50,000, respectively. For 2024, for Mr. Izenstark, the amount for time-based long-term incentive cash awards for the three-year period beginning in 2022 and paid in 2025 in the value of $101,500 was previously categorized under the column “Non-Equity Incentive Plan Compensation”.
    (8)Mr. Connell was not a NEO prior to 2024, and therefore only information related to 2024 and 2025 is presented.

The actual PSUs granted in fiscal 2025 that were earned were determined to be 105.1% of target. The Southwest PSUs granted in fiscal 2023 have been earned as a result of achieving the performance conditions during the one-year performance cycle ended on December 31, 2023, which remained subject to time-based vesting conditions and that cliff vested on January 1, 2026. The Southwest PSUs granted in fiscal 2023 that were earned were determined to be 149.8% of target. All Southwest PSUs granted to the NEOs prior to the IPO give the holders the right to receive dividend equivalents payments as and when dividends are paid on Southwest Gas Holdings common stock, which dividends are reallocated into additional equity awards of the same type and with the same vesting schedule as the original award. All time-based RSUs and PSUs granted to the NEOs after the IPO give the holders the right to receive dividend equivalents payments as and when dividend are paid on shares of Common Stock, which dividends are reallocated into additional equity awards of the same type and with the same vesting schedule as the original award. Amounts shown are rounded to the nearest share.

    Potential Payments Upon Termination or Change in Control
    Each of the NEOs is party to an Employment Agreement, pursuant to which the NEO is entitled to benefits upon the occurrence of specified termination events, both following and in the absence of a change in control. Regardless of the manner in which an NEO’s employment is terminated, the officer is entitled to receive the amount of any accrued but unpaid base salary and amounts contributed (or otherwise vested) under 401(k) or nonqualified deferred compensation plans. Mr. Connell voluntarily resigned from the Company, effective as of January 31, 2026, and did not receive any severance benefits in connection with his voluntary resignation. Therefore, his Employment Agreement is not discussed in this section.

    Following a Change in Control
    For Messrs. Brown, Izenstark and Wilcock the change in control provision of each NEO’s Employment Agreement is triggered by certain termination events occurring within 24 months following a “change in control” (as defined in the Employment Agreement, which definition is summarized below). Covered termination events include (i) a termination of employment by the employer for any reason other than the NEO’s death, disability or for cause and (ii) a resignation by the NEO for good reason, which includes a significant reduction after the change in control in the NEO’s authority, duties, responsibilities or compensation, a material breach by the Company of the Employment Agreement terms, including a change in work location, failure to continue in effect any cash or stock-based incentive or bonus plan, retirement plan, welfare benefit plan or other compensation, retirement or benefit plan and policy, unless the aggregate value of all such compensation, retirement or benefit plans and policies is not materially less than their aggregate value as in effect at any time during the 120-day period before a change in control, the Company providing notice that the term of the Employment Agreement will not be renewed, or the failure by the successor entity in the change in control to provide notice that it will honor and abide by the terms of the Employment Agreement. If one of the aforementioned termination events occurs within 24 months after a change in control or if the NEO’s employment is terminated by the Company before the change in control, but it can be shown that the termination was at the direction or request of a third party that had taken steps reasonably calculated to effect the change in control thereafter, or otherwise occurred in connection with, or in furtherance of, the change in control (referred to as a “Double-Trigger Event”), the affected NEOs would receive the following benefits (as applicable):
    •Full vesting acceleration with respect to any unvested time-based RSUs;
    Logo.jpg
    45
    2026 Proxy Statement

    Table of Contents
    •For Mr. Brown, full vesting acceleration at the target level performance with respect to any unvested performance-based equity awards;
    •A lump sum payment equal to the sum of:
    ◦a multiple (3x for Mr. Brown and 2x for Messrs. Izenstark and Wilcock) of the NEO’s salary;
    ◦for Mr. Brown, a 3x multiple of his target short-term cash annual incentive opportunity at the time of termination;
    ◦an amount equal to 100% of the target amount of any Centuri short-term incentive compensation opportunities (calculated as of the date of termination, or if greater, the change in control) for (x) the plan year preceding the date of termination and (y) a period of 24 months for Messrs. Izenstark and Wilcock following the date of termination (the “Severance Period”);
    ◦full cost of health and dental coverage for the employee and dependents and the full cost of replacement disability and life insurance for the Severance Period for Messrs. Izenstark and Wilcock;
    •Outplacement services of up to $30,000 for each of Messrs. Izenstark and Wilcock.

    The Employment Agreements generally define a “change in control” to include the following: the sale of substantially all of the operating assets of Centuri and its subsidiaries; the acquisition of more than 50% of the stock of Centuri by a group of stockholders or an entity which acquires control of Centuri; a merger or consolidation of Centuri with any other entity other than a merger or consolidation which would result in the voting securities of Centuri, as applicable, outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) 50% or more of the total voting power represented by the voting securities of Centuri, as applicable, or the surviving entity outstanding immediately after such merger or consolidation; acquisition by one person or a group of persons of at least 30% of the combined voting power of Centuri stock; or, during any two-year period, replacement of at least 50% of the Centuri directors unless the election of each new director was approved by a vote of at least three-fourths of the directors then still in office who were directors at the beginning of such period.

    Each NEO’s Employment Agreement contains non-compete and non-solicitation provisions, which apply during their employment and for a period of two years after employment ends, and also contains confidentiality and non-disparagement provisions. The NEOs’ severance payments are also subject to a release of claims against Centuri.

    The equity awards and long-term incentive awards held by the NEOs are not subject to automatic accelerated vesting upon a change in control, absent a Double Trigger Event.

    Under the assumption that a Double Trigger Event occurred on December 28, 2025, based on the terms of the Employment Agreements and Centuri’s long-term incentive program, it is estimated that the NEOs would have received the compensation presented in the following table:

    (1)For Messrs. Brown, Izenstark and Wilcock, upon a Double Trigger Event, all of the NEOs’ Southwest PSUs, all of the NEOs’ 2025 time-based RSUs and PSUs and Mr. Brown’s initial 2024 time-based RSUs would fully vest. The value of 2023 Southwest PSUs is based on the closing price of Southwest Gas Holdings common stock on the last trading day of fiscal 2025 ($80.76 per share). The value of 2024 time-based RSUs, 2025 time-based RSUs and PSUs is based on the closing price of Common Stock on the last trading day of fiscal 2025 ($25.94 per share). The value of the 2023 Southwest PSUs that the NEOs would be entitled to receive would be $308,318 for Mr. Wilcock. The value of Mr. Brown’s initial 2024 time-based RSUs that he would be entitled to receive would be $1,136,042. The value of the 2025 time-based RSUs that the NEOs would be entitled to receive would be as follows: $1,551,549 for Mr. Brown, $795,658 for Mr. Izenstark and $522,821 for Mr. Wilcock. The value of the 2025 PSUs that the NEOs would be entitled to receive would be as follows: $2,327,337 for Mr. Brown, $1,193,473 for Mr. Izenstark and $784,244 for Mr. Wilcock. The amounts above include dividends equivalents accrued, if any, on time-based RSUs, PSUs and Southwest PSUs.

    Absent a Change in Control
    Incentive programs for Messrs. Brown, Izenstark and Wilcock and the Employment Agreements provide for vesting of awards upon the occurrence of a termination without cause, for good reason, or due to death, disability or retirement in the absence of a change in control. None of the NEOs were eligible for retirement as of December 28, 2025. The following table shows the estimated payments and benefits that would be paid by Centuri to Messrs. Brown, Izenstark and Wilcock as a result of a termination of employment under these scenarios.

    •Annual Incentive Payments Made Upon Death or Disability. Centuri’s short-term incentive plan generally requires the participants to be employed by Centuri on the date that the awards are paid to receive the awards. Under Centuri’s short-term incentive plan, if employment terminates prior to the payment date as a result of death, disability, or retirement, the participants may receive a prorated portion of the award in the discretion of Centuri’s CEO or if in the case of the award of the CEO, in the discretion of the Compensation Steering Committee, which includes the CEO, Chief Financial Officer and Chief Human Resources Officer. If Messrs. Brown, Izenstark or Wilcock’s employment had terminated on December 28, 2025, as a result of death or disability and Centuri’s CEO had determined to award prorated payouts under Centuri’s short-term incentive plan, each NEO would have been eligible to receive a full annual incentive plan award because December 28, 2025 was the final day of the applicable performance period. The value for this payout is set forth in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table.
    •Long-Term Cash Incentive Payments Made Upon Death or Disability. In the event of an NEO’s death or disability that occurs after the performance cycle, all of the 2024 performance-based long-term cash award would vest based on level of achievement of the performance goal during the performance cycle. Assuming a termination due to death or disability occurred on December 28, 2025, the value of the 2024 performance-based long-term cash award that each NEO would have been entitled to would be $0 since the threshold level of performance was not achieved.
    •Southwest PSUs. For Mr. Wilcock, in the event of death or disability that occurs after the performance cycle, a pro-rata portion of the 2023 Southwest PSUs would vest based on actual level of performance, with the number of shares of Southwest Gas Holdings common stock that would vest determined by multiplying the ratio of actual months of service in the three-year performance period by the actual number of Southwest PSUs earned. Assuming a termination due to death or disability occurred on December 28, 2025, the value of the 2023 Southwest PSUs that Mr. Wilcock would have been entitled to would be $308,318. The values of the 2023 Southwest PSUs above were calculated based on a stock price of $80.76 per share (the closing price of Southwest Gas Holdings common stock on the last trading day of fiscal 2025). The above amounts include dividend equivalents on the Southwest PSUs.
    •Time-based RSUs. For Messrs. Brown, Izenstark and Wilcock, in the event of an NEO’s death or disability, the 2024 time-based RSUs relating to shares of Common Stock (including the initial 2024 time-based RSUs granted to Mr. Brown) and the 2025 time-based RSUs relating to shares of Common Stock would become fully vested. Assuming a termination due to death or disability occurred on December 28, 2025, (i) the value of the 2024 time-based RSUs relating to shares of Common Stock that the Mr. Brown would be entitled to receive would be $1,136,042, (ii) the value of the 2025 time-based RSUs relating to shares of Common Stock that the NEOs would be entitled to receive would be as follows: $1,551,549 for Mr. Brown, $795,658 for Mr. Izenstark and $522,821 for Mr. Wilcock. The values of the 2024 and 2025 time-based RSUs related to shares of Common Stock above were calculated based on a stock price $25.94 per share (the closing price of Common Stock on the last trading day of fiscal 2025). The above amounts include dividend equivalents, if any.
    •PSUs. In the event of an NEO’s death or disability that occurs during the performance cycle, a pro-rata portion of the 2025 PSUs would vest based on target level of performance, with the amount of PSUs that would vest determined by multiplying the ratio of actual months of service in the three-year performance period by the target amount of PSUs granted. Assuming a termination due to death or disability occurred on December 28, 2025, the value of the 2025 PSUs relating to shares of Common Stock that the NEOs would be entitled to receive would be as follows: $2,327,337 for Mr. Brown, $1,193,473 for Mr. Izenstark and $784,244 for Mr. Wilcock. The values of the 2025 PSUs related to shares of Common Stock above were calculated based on a stock price $25.94 per share (the closing price of Common Stock on the last trading day of fiscal 2025). The above amounts include dividend equivalents, if any.
    •Severance Payments Made Upon Termination Without Cause or For Good Reason. For Messrs. Brown, Izenstark and Wilcock, in the event of a termination by Centuri without cause or a resignation by the NEO for good reason, including any requirement that the NEO relocate or any material breach by the employer of the compensation provisions of the applicable Employment Agreement, the affected NEOs would receive the following benefits (as applicable):
    ◦a lump sum payment equal to 2x of the NEOs’ base salary;
    ◦for Mr. Brown, a 2x multiple of his target short-term cash annual incentive opportunity at the time of termination;
    ◦any unpaid short-term incentive compensation for the year prior to the year of termination;
    ◦for Mr. Brown, full vesting acceleration with respect to any unvested time-based equity awards;
    ◦for Mr. Brown, pro-rata vesting acceleration with respect to any unvested performance-based equity awards based on actual achievement; and

    •Severance Payments Upon Disability. For Messrs. Izenstark and Wilcock, in the event of a termination due to disability, each NEO’s Employment Agreement provides for a severance benefit equal to one year of the NEO’s base salary. Under the assumption that a termination occurred on December 28, 2025 due to disability, the NEOs would have been entitled to the following amounts of severance benefits pursuant to their Employment Agreements: $510,600 for Mr. Izenstark and $486,500 for Mr. Wilcock.
    •No Severance Upon Termination for Cause or Without Good Reason. In the event of a termination for cause by Centuri or a voluntary resignation by the NEO without good reason, the Employment Agreements and the incentive plans provide for no severance benefits.

    Pay Ratio Disclosure
    As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K of the Exchange Act, we are providing the following information about the relationship of the median annual total compensation of our employees and the annual total compensation of Mr. Christian I. Brown, our CEO during the applicable time period. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. For fiscal 2025, our last completed fiscal year:

    •The median annual total compensation as described below, of all employees of the Company and its consolidated subsidiaries (other than our CEO) was $91,980; and
    •The annual total compensation of our CEO as listed in the Summary Compensation Table was $4,265,042, and for purposes of the pay ratio calculation, $35,009 for the employer paid portion of our CEO’s and eligible dependents’ health care, disability and life insurance benefits was added, for a total of $4,300,051.
    •Based on this information, for fiscal 2025, the ratio of the annual total compensation as described below, of our CEO, to the median annual total compensation of all employees, as determined pursuant to Item 402(u) of Regulation S-K, was 47 to 1, which is a reasonable estimate calculated consistent with applicable rules.

    To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our CEO, we took the following steps:

    •Given the distribution of our employee population between the United States and Canada and our business segments, we used a variety of pay elements to structure the compensation arrangements of our employees. Consequently, for purposes of measuring the compensation of the employees, we selected elements of compensation that represent “base salary” (compensation paid at the normal hourly rate, excluding overtime, for hourly employees, and base cash salary for salaried employees) as the most appropriate measure of compensation to reflect annual compensation of our employees. Such compensation elements represent the fixed portion of each employee’s compensation arrangements and are paid without regard to our financial or operational performance or individual employee workloads in a given year. This compensation measure was consistently applied to all of our employees.
    •We identified the median employee as of December 29, 2024. We did not identify a new median employee as of December 28, 2025 because there has been no change in our employee population or employee compensation arrangements that we reasonably believe would significantly impact our pay ratio disclosure.
    •All of our employees are located in either the United States or Canada and our CEO is based in the United States. Therefore, we did not make any cost-of-living adjustments in identifying the “median employee.”
    •Because the number of our Canadian employees was less than 5% of the total number of employees as of December 29, 2024, the Canadian employees were excluded from the median employee calculation. The number of Canadian employees excluded was 310. As of 12/28/2025, the total number of Canadian employees was 476 and remains less than 5% of the total number of employees. The total number of United States and Canadian employees was 9,687 as of December 28, 2025.
    •For our median employee, we combined all of the elements of such employee’s compensation for fiscal 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $91,980. The difference between such employee’s base salary and the employee’s annual total compensation represents the value of such employee’s overtime and other premium pay, employer contributions to a 401(k) plan, and the value of the employer’s portion of such employee’s health care, disability and life insurance benefits.

    (8)Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period (assuming dividend reinvestment) and the difference between the Company’s stock price at the end and the beginning of the measurement period by the Company’s stock price at the beginning of the measurement period. Because we went public during 2024, the “measurement point” for purposes of calculating 2024 TSR and peer group TSR began on the date of our registration under Section 12 of the Exchange Act, which date was April 18, 2024.
    (9)Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the Company’s compensation peer group disclosed in our CD&A within the section titled “Executive Compensation - Compensation Discussion and Analysis - How We Determine Amounts Paid for Each Element of Compensation” that was used for setting 2025 executive compensation. NV5 Global, Inc was acquired in 2025 and is not included in the 2025 TSR calculation. Centuri updated its peer group in Fiscal 2024. The previous peer group included the companies described in footnote 9 excluding APi Group Corporation, Arcosa, Inc., Construction Partners, Inc. and NV5 Global, Inc. and included EMCOR Group Inc, KBR, Inc., Team, Inc. and Tetra Tech, Inc. The peer group was adjusted to improve size positions and to better align the peer group to the Company’s business operations. The TSR for the Company’s prior compensation peer group was 135.71 and 154.46 in 2024 and 2025, respectively.
    (10)Net income (loss) attributable to Common Stock in this column is the Company’s GAAP consolidated net income (loss) attributable to Common Stock reflected in the Company’s audited financial statements for the applicable year. Amounts shown in thousands (000s).
    (11)The Company-Selected Measure is Adjusted EBITDA, which is a non-GAAP measure. The measure reflects addbacks for certain one-time costs such as Separation-related costs, acquisition costs (net of current year contributions from Connect), other professional fees, CEO transition costs, severance, A/R securitization transaction fees and IPO related costs. Amounts shown in thousands (000s). Adjusted EBITDA for purposes of 2025 compensation differs from Adjusted EBITDA presented in our other filings with the SEC as stock-based compensation is not added back for compensation purposes and Adjusted EBITDA for compensation does not include the contribution from Connect.

    Analysis of Information Presented in the Pay Versus Performance Table
    As described in more detail in the section “Executive Compensation - Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, not all of those Company measures are presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with CAP (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay Versus Performance table.

    Centuri only has two years of CAP as a standalone publicly-traded company and, as of December 28, 2025 an approximately 20-month trading history. This limits our narrative description regarding the relationships of CAP to our performance measures. We expect to further expand our narrative descriptions regarding CAP and performance measures in future years.

    Centuri’s TSR compared to the TSR of our peer group is presented below. The start date for the period was April 18, 2024.

    (1)Mr. Brown, our President and CEO, has been omitted from this table because he served as a NEO of the Company during 2025. Mr. Brown’s compensation, including any director fees he earned, is included in the Summary Compensation Table of this proxy statement. Mr. Nielsen has been omitted from this table because he was appointed to the Board in March 2026, thereby receiving no compensation for 2025.
    (2)On April 16, 2025, each director serving at that time received a stock award of 7,338 RSUs, which will vest immediately on May 18, 2026. The fair value of the stock award was $151,970.
    (3)The fair value of the stock awards were determined in accordance with FASB ASC topic 718. The fair value of the stock award granted on April 16, 2025 was based on the closing price of Common Stock of $20.71 on February 17, 2025. The assumptions used to calculate these amounts use the closing price of Common Stock on the Board approval date multiplied by the units granted.

    Director Compensation Narrative
    In 2025, the Compensation Committee conducted a review of the types and amounts of director compensation to be set for the coming year. Based on that analysis, the Compensation Committee uses a retainer-based model for director cash compensation (without regular individual meeting fees) and determines the value of annual equity grants for directors based on a set dollar amount. Cash retainers are paid on a quarterly basis.

    The annual cash retainer for non-employee directors is $95,000. Additional annual cash retainers for the Chairs of the Audit, Compensation, and Nominating and Corporate Governance Committees are $20,000, $15,000 and $15,000, respectively. The additional annual cash retainer paid to our Chair of the Board is $100,000. Individual cash meeting fees are only payable when the number of meetings of the Board or a committee exceeds regularly scheduled meetings by three or more.

    A fixed dollar value of awards ($145,000 for 2025 and 2026) will be granted to non-employee directors annually in the form of equity compensation under the Company’s Omnibus Incentive Plan on the date of each of our Annual Meeting of Stockholders, with these awards vesting on the day immediately before the next Annual Meeting of Stockholders. For the 2026 equity compensation awards that will be granted on May 19, 2026, the date of the Annual Meeting, and all such awards going forward (unless and until the Compensation Committee determines otherwise), the fixed dollar value will be converted into awards of RSUs based on the volume-weighted average price of a share of Common Stock for the 20 consecutive trading days ending on the trading day before the grant date. For the 2025 equity compensation awards granted on April 16, 2025, the date of our 2025 Annual Meeting of Stockholders, each non-employee director serving at the time received an award totaling 7,338 RSUs based on the closing price of a share of Common Stock for the last trading session of 2024.

    Mr. DeMaria and Mr. Nielsen were appointed to the Board on November 11, 2025 and March 20, 2026, respectively. In connection with each such appointment, each of Mr. DeMaria and Mr. Nielsen is expected to receive a prorated portion of the 2025 equity compensation awards for non-employee directors, which, once granted on May 19, 2026, will vest on the day immediately before the next Annual Meeting of Stockholders. The prorated RSUs from the 2025 awards will be calculated based on the portion of the annual service period remaining from each director’s appointment date through May 18, 2026. The actual grant date fair value of each of Mr. DeMaria’s and Mr. Nielsen’s prorated RSU award has not yet been determined and will be measured on the grant date in accordance with FASB ASC Topic 718. Consistent with the Company’s methodology for director stock awards, the grant date fair value of the prorated stock award will be based on the closing price of Common Stock on the Board approval date multiplied by the number of units granted.

    Pursuant to our compensation policy, all non-employee directors have the option to defer receipt of equity compensation until they leave the Board. Deferred RSUs will be credited with notional dividends at the same time, in the same form, and in equivalent amounts as dividends that are payable from time to time on the underlying Common Stock. Such notional dividends
    Logo.jpg
    53
    2026 Proxy Statement

    Table of Contents
    will be valued on the date when they are credited to the directors in the form of additional deferred RSUs. When a director leaves the Board, any of his or her deferred RSUs will be converted into shares of Common Stock.

    Directors who are full-time employees of the Company or its subsidiaries receive no additional compensation for serving on the Board.
    Non-employee Director Stock Ownership Requirement
    To better align the interests of the Board with those of all stockholders, our Stock Ownership Policy require our non-employee directors to accumulate at least five times the value of their annual cash retainer in Common Stock within five years of the beginning of their board service. All non-employee directors are currently in compliance or working towards compliance with our Stock Ownership Policy.

    ADVISORY VOTE TO APPROVE THE COMPANY’S EXECUTIVE COMPENSATION
    (Proposal 2 on the Proxy Card)

    The Board Recommends a Vote “FOR” the Proposal to Approve the Company’s Executive Compensation
    General
    Pursuant to Section 14A of the Exchange Act, we are asking our stockholders to vote on a non-binding, advisory basis, to approve our executive compensation program as described in this Proxy Statement, commonly referred to as the “say-on-pay” vote. The Board asks that you support the compensation of our NEOs as disclosed in the “Executive Compensation - Compensation Discussion and Analysis” section and the accompanying tables and narratives contained in this Proxy Statement. Because your vote is advisory, it will not be binding on the Board or the Company. However, the Board and the Compensation Committee will review the voting results and take them into consideration when making future decisions regarding executive compensation.

    The Company’s compensation program is designed and administered by the Compensation Committee of the Board, which carefully considers many different factors, as described in the “Executive Compensation - Compensation Discussion and Analysis” section, to provide appropriate compensation for the Company’s executives. As discussed in the “Executive Compensation - Compensation Discussion and Analysis” section, the compensation package for the Company’s NEOs is designed to support the Company’s objectives of attracting, motivating and retaining the executive talent required to achieve our corporate objectives and increase stockholder value.

    The executive compensation program in which the Company’s NEOs participate contain certain key governance practices, including the following: (i) a balanced mix of cash and equity compensation, and of short-term and long-term incentives; (ii) an emphasis on pay-for-performance to align executive compensation with the execution of business strategies and the creation of long-term stockholder value; (iii) a prohibition on pledging Company securities or entering into hedging, monetization transactions or similar arrangements involving Company securities; (iv) perquisites only to the extent that they are reasonable and consistent with the compensation goal of attracting and retaining superior executives for key positions; (v) clawback policies that comply with applicable legal and stock exchange listing requirements; and (vi) use of an independent consultant by the Compensation Committee to assist in designing compensation programs and making compensation decisions.
     
    Consistent with the SEC rule implementing the requirement that the Company periodically include a say-on-pay proposal in its proxy statement, the vote on this proposal is advisory and is not binding on the Company, the Compensation Committee or the Board. The Compensation Committee and the Board value the opinions that stockholders express in their votes and to the extent there is any significant vote against the NEO compensation, we will consider the outcome of the vote when making future executive compensation decisions and evaluate whether any actions are necessary to address stockholder concerns expressed by such vote. It is expected that the next advisory vote on executive compensation will occur at the 2027 Annual Meeting of Stockholders (the “2027 Annual Meeting”).

    We encourage you to review the complete description of the Company’s executive compensation program provided in this Proxy Statement, including the “Executive Compensation - Compensation Discussion and Analysis” section and the accompanying compensation tables. The Board recommends that our stockholders vote “FOR,” on an advisory basis, the compensation paid to our NEOs, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC.

    APPROVAL OF CENTURI EMPLOYEE STOCK PURCHASE PLAN
    (Proposal 3 on the Proxy Card)

    The Board Recommends a Vote “FOR” for the Centuri Employee Stock Purchase Plan.

    General
    We are asking our stockholders to approve the Centuri Employee Stock Purchase Plan (the “ESPP”). The ESPP was adopted by the Board on April 2, 2026, subject to the approval of our stockholders. If this Proposal 3 is approved by our stockholders, the ESPP will become effective on May 19, 2026. If our stockholders do not approve this Proposal 3, the ESPP will not become effective, and no shares of Common Stock will be issued under the ESPP.

    Summary of the ESPP
    The material features of the ESPP are described below. The following description of the ESPP is a summary only and is qualified in its entirety by reference to the complete text of the ESPP, which is attached hereto as Annex A. Stockholders are urged to read the actual text of the ESPP in its entirety.

    Purpose
    The purpose of the ESPP is to provide eligible employees of the Company and its subsidiaries and affiliates that are designated to participate in the ESPP (the “designated companies”) with an opportunity to purchase shares of Common Stock through contributions in the form of payroll deductions or otherwise to the extent permitted by the Administrator (as defined below).

    The ESPP includes two components: a 423 Component and a Non-423 Component (as each such term is defined in the ESPP). The 423 Component is designed to allow eligible U.S. employees to purchase shares in a manner that is intended to qualify for favorable tax treatment under Section 423 of the Internal Revenue Code of 1986, as amended (the “Code”). In addition, options may be granted under the Non-423 Component, which is not intended to qualify for such favorable tax treatment. The Non-423 Component will operate and be administered in the same manner as the 423 Component, unless otherwise required or advisable under applicable foreign laws.

    Administration
    The ESPP is administered by the Board or any committee of the Board designated by the Board to administer the ESPP (the “Administrator”). The Board has designated the Compensation Committee as the Administrator. The Administrator has full and exclusive discretionary authority to construe, interpret and apply the terms of the ESPP, to delegate ministerial duties to any of our employees, to designate separate offerings under the ESPP, to select designated companies, to determine eligibility, to adjudicate all disputed claims filed under the ESPP and to establish procedures that it deems necessary for the administration of the ESPP, such as adopting such procedures, sub-plans and special rules as are necessary or appropriate to permit participation in the ESPP by employees who are foreign nationals or employed outside the U.S. The Administrator’s findings, decisions and determinations will be final and binding on all participants to the full extent permitted by law.

    Shares Subject to the ESPP
    Subject to adjustment for certain changes in our capitalization (as described in more detail in Adjustments below), the maximum number of shares of Common Stock that are available for issuance under the ESPP is 4,033,781 shares.

    Eligibility
    Generally, all of our employees and employees of our designated companies are eligible to participate if they are customarily employed by the Company, or any participating subsidiary or affiliate, for at least 20 hours per week and more than five months in any calendar year. The Administrator will have the discretion, prior to an enrollment date for all options granted on such enrollment date in an offering, to determine that an employee who (i) has not completed at least two years of service (or a lesser period of time determined by the Administrator) since the employee’s last hire date, (ii) customarily works not more than 20 hours per week (or a lesser period of time determined by the Administrator), (iii) customarily works not more than five months per calendar year (or a lesser period of time determined by the Administrator), (iv) is a highly compensated employee within the

    meaning of Section 414(q) of the Code or (v) is an officer or subject to disclosure requirements under Section 16(a) of the Exchange Act, is or is not eligible to participate in such offering period.

    A participant may not be granted an option to purchase shares under the Section 423 Component of the ESPP if the participant would, immediately after the grant, (i) own shares possessing 5% or more of the total combined voting power or value of all classes of our shares or (ii) hold options to purchase shares under all of our employee stock purchase plans that accrue at a rate that exceeds $25,000 worth of shares, determined on the grant date (which is the first trading day of each offering period), for each calendar year in which such option is outstanding at any time.

    As of December 28, 2025, approximately 9,600 employees met the eligibility requirements for participation in the ESPP.

    Offerings
    The ESPP is implemented by offerings of options to purchase shares of Common Stock to all eligible employees. The ESPP provides for consecutive offering periods that will typically have a duration of approximately six months. The offering periods are scheduled to start on the first trading day on or after March 16 and September 16 of each year. The Administrator has the authority to change the duration of each offering period prior to its commencement, provided that no offering period may exceed 27 months. The Administrator may establish separate offerings which vary in terms (although not inconsistent with the provisions of the ESPP or the requirements of applicable laws). When an eligible employee elects to participate in an offering period, the employee is granted an option on the grant date to purchase shares on the exercise date (which is the last trading day of each offering period). On the exercise date, all contributions collected from the participant are automatically applied to the purchase of shares, subject to certain limitations (which are described in Eligibility above and Limits on Employee Contributions; Exercise of Option below).

    Limits on Employee Contributions; Exercise of Option
    The ESPP permits participants to purchase shares through payroll deductions or otherwise of up to 10% of their eligible compensation (capped at $10,000 per offering period). A participant will be able to purchase a maximum of 500 shares during an offering period. Unless the Administrator provides otherwise, offering periods for all offering periods will (i) commence on the first trading day on or after March 16 and September 16 and (ii) terminate on the last trading day on or before September 15 of the same year and March 15 of the following year, respectively.

    Amounts deducted and accumulated by a participant are used to purchase shares on the exercise date. The purchase price of the shares under the 423 Component is 85% of the fair market value of a share on the grant date or on the exercise date, whichever is lower. Under the Non-423 Component of the ESPP, the purchase price of the shares is the same as under the 423 Component, unless the Board or the Administrator determines that the purchase price applicable to any offering period or purchase by Canadian participants will instead be equal to the fair market value of a share on the grant date.

    Restrictions on Transfer
    A participant is not able to assign, transfer, pledge or otherwise dispose of an option granted under the ESPP (other than by will, the laws of descent and distribution or as otherwise provided under the ESPP).

    Adjustments
    If a corporate event occurs that impacts any class of our shares, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the ESPP, will, in such manner as it may deem equitable, adjust (i) the number and class of shares that may be delivered under the ESPP, (ii) the purchase price per share and the number of shares covered by each option under the ESPP that has not yet been exercised, and (iii) the number of shares that may be purchased during an offering period and made available under the ESPP. In the event of a proposed dissolution, liquidation, merger or change in control, any offering period in progress and outstanding options will be treated as set forth in the ESPP.

    Amendment and Termination
    The Board or the Administrator may amend, suspend or terminate the ESPP at any time. If the ESPP is terminated, the Board or the Administrator may elect to (i) terminate all outstanding offering periods either immediately or upon completion of the purchase of shares under the ESPP (which may be sooner than originally scheduled, if determined by the Administrator) or (ii) permit offering periods to expire in accordance with their terms (and subject to any adjustment). If an offering period is terminated prior to expiration, all amounts then credited to a participant’s account that have not been used to purchase shares

    Table of Contents
    under the ESPP will be returned to the participant as soon as administratively practicable, without interest unless required by law. The ESPP will automatically terminate in 2036 unless the Board or the Administrator terminates it sooner.

    Federal Income Tax Consequences
    The two subsections below summarize the principal U.S. federal income tax consequences to participants and us with respect to participation in the 423 Component of the ESPP and the Non-423 Component of the ESPP. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based on current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on the participant’s particular situation, each participant should consult the participant’s tax advisor regarding the federal, state, local and other tax consequences of the grant or exercise of an option or the sale or other disposition of shares acquired under the ESPP. The ESPP is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

    423 Component of the ESPP
    The 423 Component of the ESPP, and the rights of participant employees to make purchases thereunder, are intended to qualify for treatment under the provisions of Sections 421 and 423 of the Code. Under these provisions, generally no income tax consequences arise when participants purchase shares under the ESPP and no income will be taxable to a participant until the shares purchased under the ESPP are sold or otherwise disposed of.

    On sale or other disposition of the shares, the participant will generally be subject to tax and the amount of the tax will depend on the holding period. If the shares are sold or otherwise disposed of more than two years after the grant date (and more than one year after the exercise date), then the participant generally will recognize ordinary income measured as the lesser of:

    1.the excess of the fair market value of the shares at the time of such sale or disposition over the purchase price of such shares, or
    2.an amount equal to 15% of the fair market value of the shares on the grant date.

    Any additional gain should be treated as long-term capital gain. If the shares are held for at least the holding periods described above but are sold for a price that is less than the purchase price, there will be no ordinary income and the difference will be a long-term capital loss. We will not be entitled to an income tax deduction with respect to the grant or exercise of an option to purchase shares, or the sale of the shares by a participant, where the participant holds the shares for at least the holding periods described above.

    Any sale or other disposition of shares before the expiration of the holding periods described above will be a “disqualifying disposition,” and the participant will recognize ordinary income at the time of the disposition, generally measured as the difference between the purchase price the participant paid for the shares and the fair market value of the shares on the purchase date, and we will be entitled to an income tax deduction for such ordinary income. If a participant makes a disqualifying disposition at a price in excess of the purchase price that the participant paid for the shares, the participant will recognize capital gain in an amount equal to the difference between the selling price of the shares and the fair market value of the shares on the purchase date. If a participant makes a disqualifying disposition at a price less than the fair market value of the shares on the purchase date, the participant will recognize a capital loss in an amount equal to the difference between the fair market value of the shares on the purchase date and the sale price of the shares. We will not be entitled to an income tax deduction with respect to any capital gain the participant recognizes as a result of a disqualifying disposition.

    Non-423 Component of the ESPP
    The Non-423 Component of the ESPP, and the rights of participant employees to make purchases thereunder, are not intended to qualify for treatment under the provisions of Sections 421 and 423 of the Code.

    If an option is granted under the Non-423 Component of the ESPP, then to the extent a participant is subject to U.S. federal income tax, the amount equal to the excess (if any) of the fair market value of the shares on the purchase date over the purchase price will be taxed as ordinary income at the time of purchase, and the participant will be subject to all applicable tax withholding requirements. The amount of such ordinary income will be added to the participant’s basis in the shares, and any additional gain or resulting loss recognized on the disposition of the shares after such basis adjustment will be subject to capital gain or loss treatment. A capital gain or loss will be long-term if the participant holds the shares for more than one year after the
    Logo.jpg

    Table of Contents
    purchase date. The company may be entitled to a deduction in the year of purchase equal to the amount of ordinary income realized by the participant.

    New Plan Benefits
    Participation in the ESPP is voluntary and each eligible employee will make his or her own decision regarding whether and to what extent to participate in the ESPP. Accordingly, the benefits or amounts that will be received by or allocated to our executive officers and other employees under the ESPP, as well as the benefits or amounts which would have been received by or allocated to our executive officers and other employees for fiscal year 2026 if the ESPP had been in effect, are not determinable.

    SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
    (Proposal 4 on the Proxy Card)

    The Board Recommends a
    Vote “FOR” Auditor Ratification
    General
    The Audit Committee selected PricewaterhouseCoopers LLP as the independent registered public accounting firm for the Company for the year ending January 3, 2027, subject to ratification of the selection by the stockholders.

    PricewaterhouseCoopers LLP has been the Company’s independent public accounting firm since 2002. To the Audit Committee’s knowledge, at no time has PricewaterhouseCoopers LLP had any direct or indirect financial interest in or connection with the Company or any of our subsidiaries other than for services rendered to the Company as described below.

    The Audit Committee is composed of independent directors and meets periodically with the Company’s internal auditors and PricewaterhouseCoopers LLP to review the scope and results of the audit function and the policies relating to auditing procedures. In making its annual recommendation, the Audit Committee reviews both the audit scope and proposed fees for the coming year.

    The affirmative vote of a majority of the shares represented and voting at the Annual Meeting or by proxy is necessary to ratify the selection of PricewaterhouseCoopers LLP as the independent registered public accounting firm for the Company. If the selection of PricewaterhouseCoopers LLP is not ratified by stockholders, the Audit Committee will review its future selection of the independent registered public accounting firm in light of the results of the vote. Even if the selection is ratified, the Audit Committee in its discretion may appoint a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such change would be appropriate.

    During fiscal 2025 and fiscal 2024, PricewaterhouseCoopers LLP provided the following audit, audit-related and other professional services for the Company. The cost and description of these services are as follows:
    2025 ($)
    2024 ($)
    Audit Fees(1)
    3,106,000 2,959,000 
    Audit-Related Fees(2)
    — — 
    Tax Fees(3)
    50,474 56,861 
    All Other Fees(4)
    2,158 — 
    Total3,158,6323,015,861
    (1)Consists of fees incurred for professional services rendered in connection with the audit of our annual consolidated financial statements, reviews of our quarterly consolidated financial statements, and issuances of consents and other services related to SEC matters. This category also includes fees in connection with our initial public offering and accounting consultations and audit services incurred in connection with nonrecurring transactions.
    (2)Consists of fees incurred for assurance and related services that were reasonably related to the performance of the audit or review of our consolidated financial statements and which were not reported above under “Audit Fees.” For fiscal 2025 and fiscal 2024, there were no such services.
    (3)Consists of fees incurred for professional services for tax planning, tax consulting, and tax compliance services.
    (4)Consists of fees incurred for software used by management in ensuring completeness of financial statement disclosures. For fiscal 2024 there were no such services.

    Under the Audit Committee’s charter, the Audit Committee must preapprove all Company engagements of PricewaterhouseCoopers LLP, unless an exception exists under the provisions of the Exchange Act or applicable SEC rules. At the beginning of each audit cycle, the Audit Committee evaluates the anticipated engagements of PricewaterhouseCoopers LLP, including the scope of work proposed to be performed and the proposed fees, and approves or rejects each service, consistent with its preapproval policy, taking into account whether the services are permissible under applicable laws and the possible impact of each nonaudit service on PricewaterhouseCoopers LLP’s independence from management. The Audit Committee also considers whether PricewaterhouseCoopers LLP is best positioned to provide effective and efficient service, and whether the service may enhance the Company’s ability to manage and control risk or improve audit quality. Throughout the year, the Audit Committee reviews updates of the actual services provided and fees charged by PricewaterhouseCoopers LLP.

    Requests for PricewaterhouseCoopers LLP to provide additional services are presented to the Audit Committee by the Company’s Chief Financial Officer or Chief Accounting Officer, on an as-needed basis. The Audit Committee has delegated to the chairperson of the Audit Committee the authority to evaluate and approve engagements on the Audit Committee’s behalf in the event that a need arises for preapproval between Audit Committee meetings. Approval of additional services will be made
    Logo.jpg
    60
    2026 Proxy Statement

    Table of Contents
    consistent with the preapproval policy and will be presented to the Audit Committee for ratification at its next scheduled meeting.

    Since the effective date of the preapproval process, the Audit Committee has approved, in advance, each new engagement of PricewaterhouseCoopers LLP, and none of those engagements made use of the de minimis exception to the preapproval requirement contained in the SEC rules.

    Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting. They will have the opportunity to make statements, if they are so inclined, and will be available to respond to appropriate questions.

    AUDIT COMMITTEE REPORT

    The Audit Committee is composed of four members of the Board. The Board determined that each member of the Audit Committee qualifies as independent under the independence standards of the NYSE and the SEC.

    The Audit Committee assists the Board in fulfilling its oversight responsibility by reviewing the financial information provided to stockholders and others, the system of internal control that management and the Board have established, and the audit process. Management is responsible for the Company’s consolidated financial statements, for maintaining effective internal control over the Company’s financial reporting, and for its assessment of the effectiveness of internal control over financial reporting. PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, is required to plan and perform an integrated audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects, and to issue a report thereon. The Audit Committee’s role and responsibilities are to monitor and oversee these processes as set forth in a written Audit Committee charter adopted by the Board. The Audit Committee charter is available on the Company’s website at www.centuri.com. The Audit Committee reviews and assesses the adequacy of the charter at least annually and recommends any changes to the Board for approval.

    In fulfilling the Audit Committee’s responsibilities for 2025, the Audit Committee:
    •Reviewed and discussed the audited consolidated financial statements for the fiscal year ended December 28, 2025 with management and PricewaterhouseCoopers LLP;
    •Discussed with PricewaterhouseCoopers LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and the SEC; and
    •Received the written disclosures and the letter from PricewaterhouseCoopers LLP required by the applicable requirements of the PCAOB regarding its communications with the Audit Committee concerning independence, and the Audit Committee discussed with PricewaterhouseCoopers LLP its independence.

    Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements for the fiscal year ended December 28, 2025 be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 28, 2025, filed with the SEC.

    EMPLOYEE STOCK PURCHASE PLAN
    1.    Purpose. The purpose of the Plan is to provide employees of the Company and its Designated Companies with an opportunity to purchase Shares through accumulated Contributions. The Company intends for the Plan to have two components: a component that is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code (the “423 Component”) and a component that is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code (the “Non-423 Component”). The provisions of the 423 Component, accordingly, will be construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. An option to purchase Shares under the Non-423 Component will be granted pursuant to rules, procedures, or sub-plans adopted by the Administrator designed to achieve tax, securities laws, or other objectives for Eligible Employees and the Company. Except as otherwise provided herein, the Non-423 Component will operate and be administered in the same manner as the 423 Component.

To the extent permitted by Treasury Regulation Section 1.423-2(a)(1), the terms of each Offering need not be identical provided that the terms of the Plan and an Offering together satisfy Treasury Regulation Section 1.423-2(a)(2) and (a)(3).

In the case of the Non-423 Component, Eligible Employees
    67

    Table of Contents
    may be excluded from participation in the Plan or an Offering if the Administrator determines that participation of such Eligible Employees is not advisable or practicable.
    (c)    Limitations. Any provisions of the Plan to the contrary notwithstanding, no Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that the Participant’s rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate, which exceeds $25,000 worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for each calendar year in which such option is outstanding at any time, as determined in accordance with Section 423 of the Code.
    4.    Offering Periods. The Plan will be implemented by consecutive Offering Periods with a new Offering Period commencing on the first Trading Day on or after March 16 and September 16 each year, or on such other dates as the Administrator will determine. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future Offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter; provided, however, that no Offering Period may last more than 27 months.
    5.    Participation. An Eligible Employee may participate in the Plan by (i) submitting to the Company’s designee a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose or (ii) following an electronic or other enrollment procedure determined by the Administrator, in either case on or before a date determined by the Administrator prior to the applicable Enrollment Date.
    6.    Contributions.
    (a)    At the time a Participant enrolls in the Plan pursuant to Section 5, the Participant will elect to have Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the Offering Period in an amount not exceeding 10% of the Compensation that the Participant receives on the pay day; provided that the aggregate amount of Participant’s Contributions made during the Offering Period may not exceed $10,000. The Administrator, in its sole discretion, may permit all Participants in an Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Offering Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10.
    (b)    If Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day on or prior to the last Exercise Date of such Offering Period to which such authorization applies, unless sooner terminated by the Participant as provided in Section 10.
    (c)    All Contributions made for a Participant will be credited to the Participant’s account under the Plan and Contributions will be made in whole percentages of the Participant’s Compensation only. A Participant may not make any additional payments into such account.
    (d)    A Participant may discontinue the Participant’s participation in the Plan as provided under Section 10. Unless otherwise determined by the Administrator, during an Offering Period, a Participant may not increase or decrease the rate of the Participant’s Contributions. The Administrator may, in its sole discretion, amend the nature and/or number of Contribution rate changes that may be made by
    68

    Table of Contents
    Participants during any Offering Period and may establish other conditions or limitations as it deems appropriate for Plan administration.
    (e)    Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(d), a Participant’s Contributions may be decreased to 0% at any time during an Offering Period. Subject to Section 423(b)(8) of the Code and Section 3(d), Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Offering Period scheduled to begin in the following calendar year, unless terminated by the Participant as provided in Section 10.
    (f)    Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Participants to participate in the Plan via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted under applicable local law, (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code; or (iii) the Participants are participating in the Non-423 Component.
    (g)    At the time the option is exercised, in whole or in part, or at the time some or all of the Shares issued under the Plan are disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Shares (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to the sale or early disposition of Shares by the Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Shares or any other method of withholding the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).
    7.    Grant of Option. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on the Exercise Date of such Offering Period (at the applicable Purchase Price) up to a number of Shares determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be permitted to purchase during any Offering Period more than 500 Shares (subject to any adjustment pursuant to Section 20); provided further that such purchase will be subject to the limitations set forth in Sections 3(d) and 13. The Eligible Employee may accept the grant of such option by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of Shares that an Eligible Employee may purchase during each Offering Period. Exercise of the option will occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10. The option will expire on the last day of the Offering Period.
    8.    Exercise of Option.
    (a)    Unless a Participant withdraws from the Plan as provided in Section 10, the Participant’s option for the purchase of Shares will be exercised automatically on each Exercise Date, and the maximum number of full Shares subject to the option will be purchased for the Participant at the applicable Purchase Price with the accumulated Contributions from the Participant’s account. No fractional Shares will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full Share will be retained in the Participant’s account for the subsequent Offering Period, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the Participant. During a Participant’s lifetime, a Participant’s option to purchase Shares hereunder is exercisable only by the Participant.
    69

    Table of Contents
    (b)    If the Administrator determines that, on an Exercise Date, the number of Shares with respect to which options are to be exercised may exceed (i) the number of Shares that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of Shares available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the Shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Shares on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the Shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Shares on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 21. The Company may make a pro rata allocation of the Shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional Shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date.
    9.    Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of Shares occurs, the Company will arrange the delivery to each Participant of the Shares purchased upon exercise of the Participant’s option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that Shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that Shares be retained with such broker or agent for a designated period and/or may establish other procedures to permit tracking of disqualifying dispositions of Shares. No Participant will have any voting, dividend, or other stockholder rights with respect to Shares subject to any option granted under the Plan until such Shares have been purchased and delivered to the Participant as provided in this Section 9.
    10.    Withdrawal.
    (a)    A Participant may withdraw all, but not less than all, of the Contributions credited to the Participant’s account and not yet used to exercise the Participant’s option under the Plan at any time that is at least 30 days prior to the end of an Offering Period (or such other date determined by the Administrator) by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose, or (ii) following an electronic or other withdrawal procedure determined by the Administrator; provided that a Participant may not withdraw during any blackout period applicable to the Participant. All of the Participant’s Contributions credited to the Participant’s account will be paid to the Participant as soon as administratively feasible after receipt of notice of withdrawal and the Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of Shares will be made for such Offering Period.
    (b)    A Participant’s withdrawal from an Offering Period will not have any effect on the Participant’s eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws, except that the Participant will not be permitted to participate in the immediately subsequent Offering Period unless otherwise determined by the Administrator. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of any succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5.
    11.    Termination of Employment. Unless otherwise provided by the Administrator, upon a Participant’s ceasing to be an Eligible Employee for any reason, the Participant will be deemed to have elected to withdraw from the Plan and the Contributions credited to the Participant’s account during the Offering Period but not yet used to purchase Shares under the Plan will be returned to the Participant or, in the case of the Participant’s death, to the person or persons entitled thereto under Section 16, and the Participant’s option will be automatically terminated. Unless otherwise provided by the Administrator, a Participant whose employment transfers between
    70

    Table of Contents
    entities through a termination with an immediate rehire (with no break in service) by the Company or a Designated Company will not be treated as terminated under the Plan; however, if a Participant transfers from an Offering under the 423 Component to the Non-423 Component, the exercise of the option will be qualified under the 423 Component only to the extent it complies with Section 423 of the Code, unless otherwise provided by the Administrator.
    12.    Interest. No interest will accrue on the Contributions of a Participant in the Plan, except as may be required by Applicable Law, as determined by the Company, and if so required by the laws of a particular jurisdiction, will apply to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f).
    13.    Stock.
    (a)    Subject to adjustment upon changes in capitalization of the Company as provided in Section 20, the maximum number of Shares that will be made available for sale under the Plan will be 4,033,781 Shares.
    (b)    Until Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a Participant will have only the rights of an unsecured creditor with respect to such Shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such Shares.
    (c)    Shares to be delivered to a Participant under the Plan will be registered in the name of the Participant or in the name of the Participant and the Participant’s spouse.
    14.    Administration.
    (a)    The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to delegate ministerial duties to any of the Company’s employees, to designate separate Offerings under the Plan, to designate Subsidiaries and Affiliates of the Company as participating in the 423 Component or Non-423 Component, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan (including, without limitation, to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans may take precedence over other provisions of the Plan, with the exception of Section 13(a), but unless otherwise superseded by the terms of such sub-plan, the provisions of the Plan will govern the operation of such sub-plan). Unless otherwise determined by the Administrator, the Eligible Employees eligible to participate in each sub-plan will participate in a separate Offering or in the Non-423 Component.
    (b)    Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. The Administrator is also authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to employees resident solely in the U.S. Every finding, decision, and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties.

    Table of Contents
    15.    Indemnification. In addition to such other rights of indemnification as they may have as members of the Board or as officers or employees, members of the Board and any officers or employees to whom authority to act for the Board, the Committee or the Company is delegated shall be defended and indemnified by the Company to the extent permitted by Applicable Laws on an after-tax basis against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any claim, investigation, action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any Award, and against all amounts paid by them in settlement thereof (provided such settlement is approved by the Company) or paid by them in satisfaction of a judgment in any such claim, investigation, action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such claim, investigation, action, suit or proceeding that such individual is liable for gross negligence, bad faith or intentional misconduct; provided, however, that within 30 days after the institution of such claim, investigation, action, suit or proceeding, such individual shall offer to the Company, in writing, the opportunity at the Company’s expense to defend the same.
    16.    Designation of Beneficiary.
    (a)    If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any Shares and cash, if any, from the Participant’s account under the Plan in the event of the Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to the Participant of such Shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of the Participant’s death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.
    (b)    Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of the Participant’s death, the Company will deliver such Shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such Shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.
    (c)    All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding Sections 15(a) and (b), the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).
    17.    Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way by the Participant (other than by will, the laws of descent and distribution or as provided in Section 16). Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10.
    18.    Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such Contributions except under Offerings or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to the Plan by Participants be segregated from the Company’s general corporate funds and/or deposited with an independent third party.
    72

    Table of Contents
    19.    Reports. An individual account will be maintained for each Participant in the Plan. Statements of account will be given to Participants at least annually, which will set forth the amounts of Contributions, the Purchase Price, the number of Shares purchased and the remaining cash balance, if any.
    20.    Adjustments, Dissolution, Liquidation, Merger, or Change in Control.
    (a)    Adjustments. If the Company subdivides its outstanding shares into a greater number of shares (by share dividend, share split, reclassification, alteration of capital, capitalization of profits or otherwise) or combines its outstanding Shares into a smaller number of Shares (by consolidation, reclassification, amalgamation or otherwise) or if the Administrator determines that there is any variation in the share capital of the Company or that there is any share dividend, extraordinary cash dividend, alteration of capital, capitalization of profits, bonus issue, reclassification, recapitalization, reorganization, amalgamation, consolidation, split-up, spin-off, combination, exchange of shares, warrants or rights offering to purchase any class of shares or other similar corporate event) affects any class of shares, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of shares that may be delivered under the Plan, the Purchase Price per share and the number of shares covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13.
    (b)    Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10.
    (c)    Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. If the successor corporation or a Parent or Subsidiary of the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period will end. The New Exercise Date will occur before the date of the proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10.
    21.    Amendment or Termination.
    (a)    The Board or the Administrator, in its sole discretion, may amend, suspend or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Board or the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of Shares on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 20). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase Shares will be returned to the Participants (without interest thereon, except as otherwise required under Applicable Laws, as further set forth in Section 12) as soon as administratively practicable.
    73

    Table of Contents
    (b)    Without stockholder consent and without limiting Section 21(a), the Administrator will be entitled to change the Offering Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit Contributions in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Shares for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent with the Plan.
    (c)    If the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequences, including, but not limited to:
    (i)    amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;
    (ii)    altering the Purchase Price for any Offering Period, including an Offering Period underway at the time of the change in Purchase Price;
    (iii)    shortening any Offering Period by setting a New Exercise Date, including an Offering Period underway at the time of the Administrator action;
    (iv)    reducing the maximum percentage of Compensation a Participant may elect to set aside as Contributions; and
    (v)    reducing the maximum number of Shares a Participant may purchase during any Offering Period.
    Such modifications or amendments will not require stockholder approval or the consent of any Participants. Notwithstanding the foregoing, no such modification or amendment shall be permitted if, under Section 424(h)(3) of the Code, they would be deemed a modification, extension or renewal of options granted under the Plan.
    22.    Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.
    23.    Conditions Upon Issuance of Shares.
    (a)    Shares will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such Shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance.
    (b)    As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute the Shares if, in the opinion of counsel for the Company, such a representation is required by Applicable Laws.
    74

    Table of Contents
    24.    Section 409A. The 423 Component of the Plan is exempt from the application of Section 409A of the Code (“Section 409A”) and any ambiguities herein will be interpreted to be so exempt from Section 409A. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action that the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from, or to allow any such options to comply with, Section 409A, but only to the extent any such amendments or action by the Administrator would not violate Section 409A. Notwithstanding the foregoing, the Company will have no liability to a Participant or any other party if an option to purchase Shares under the Plan that is intended to be exempt from, or compliant with, Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the option to purchase Shares under the Plan is exempt from, or complies with, Section 409A.
    25.    Term of Plan. The Plan is effective upon its adoption by the Board, subject to stockholder approval of the Plan pursuant to Section 26. It will continue in effect for a term of 10 years, unless sooner terminated under Section 21.
    26.    Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within 12 months after the date on which the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.
    27.    Equal Rights and Privileges. Notwithstanding any provision of the Plan to the contrary, in accordance with Section 423 of the Code, all Eligible Employees who are granted options under the Plan shall have the same rights and privileges.
    28.    Governing Law. The Plan shall be interpreted and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of laws rules of such state, to the extent not preempted by federal law.
    29.    Jurisdiction; Choice of Forum. Any suit, action or proceeding relating to or arising out of this Plan, or any judgment entered by any court of competent jurisdiction in respect thereof (a “Proceeding”), shall be brought only in the federal or state courts located in Phoenix, Arizona. The Company and each Participant shall irrevocably and unconditionally (a) consent and submit to the exclusive jurisdiction of the courts of the State of Arizona, the United States District Court for the District of Arizona, and appellate courts having jurisdiction of appeals from any of the foregoing, and agree that all claims in respect of any such Proceeding shall be heard and determined in such Arizona court or, to the extent permitted by law, in such federal court, (b) waive any objection that the Company and each Participant may now or thereafter have to the venue or jurisdiction for any such Proceeding in any such court or that such Proceeding was brought in an inconvenient forum and agree not to plead or claim the same, and (c) agree that service of process in any such Proceeding may be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party, in the case of a Participant, at the Participant’s address shown in the books and records of the Company or, in the case of the Company, at the Company’s principal offices, attention General Counsel.
    30.    No Right to Employment. Participation in the Plan by a Participant will not be construed as giving the Participant the right to be retained as an employee of the Company or a Subsidiary or Affiliate of the Company, as applicable. Further, the Company or a Subsidiary or Affiliate of the Company may dismiss a Participant from employment at any time, free from any liability or any claim under the Plan, unless otherwise required pursuant to Applicable Laws.
    31.    Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.
