At-Will Employment

This letter is merely a summary of the principal terms of our employment offer and is not a contract of employment for any definite period of time and does not otherwise confer any contractual rights whatsoever. In accepting our offer of employment, you certify your understanding that your employment will be on an at-will basis. As an at-will employee, you will be free to terminate your employment with the Company at any time, with or without cause or advance notice (other than the notice contemplated in the definition of Good Reason, if applicable). Similarly, the Company is free to terminate your employment at any time, with or without cause, or advance notice (other than the notice contemplated in the definition of Cause, if applicable).

Severance

Termination by the Company for Cause or by you other than for Good Reason. If your employment is terminated by the Company for “Cause” or by you other than for “Good Reason,” you will not receive any severance benefits, other than any accrued but unpaid salary, any vested employee benefits and equity awards to which you are entitled under the terms of the applicable benefit plan or award agreement, as applicable, and any other benefits required by applicable law (the “Accrued Obligations”).

For purposes of this offer letter, “Cause” means: (a) negligence in the performance of, intentional nonperformance of, or inattention to your material duties and responsibilities hereunder, any of which continue for 30 business days after receipt of written notice of need to cure the same; (b) your willful dishonesty, fraud or material misconduct with respect to the business or affairs of the Company; (c) your violation of any of the Company’s policies or procedures, which violation is not cured by Employee within 30 business days after you have been given written notice thereof; (d) your conviction of, a plea of nolo contendere to, or a guilty plea or a confession by you to an act of fraud, misappropriation or embezzlement or any crime punishable as a felony or any other crime that involves moral turpitude; (e) your use of illegal substances or habitual drunkenness that interferes with your ability to discharge your duties, responsibilities, or obligations to the Company, as determined in the Board’s sole discretion; or (f) the breach by you of a material provision of this offer letter if you do not cure such breach within 30 business days after you have been given written notice thereof.

For purposes of this offer letter, “Good Reason” means (a) assignment of any duties that are materially inconsistent with your position (including offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by this offer letter; (b) the Company moving your primary work location outside the Phoenix, Arizona area (other than pursuant to a work-from-home mandate); or (c) any material breach of this offer letter by the Company; provided, that a termination will not be deemed to be a termination for Good Reason unless you have provided written notice to the Company of the existence of the condition(s) described above within 90 days of the initial existence of the condition(s), the Company has failed to cure the condition(s) within 30 days after such notice is received, and your employment terminates within 30 days after the cure period ends.

Termination by the Company without Cause or by you for Good Reason. If your employment is terminated by the Company without Cause (other than due to your Disability (as defined below)) or by you for Good Reason, you will be entitled to any Accrued Obligations and, subject to your execution of a general release of claims in the form provided by the Company and such release becoming effective and irrevocable within 60 days after the date your employment terminates, you will also (a) be entitled to receive a lump sum payment equal (before deductions required by law) to the product of (x) and (y), where (x) is the sum of your annual base salary and target short-term cash annual incentive opportunity at the time of termination and (y) is 2, if the termination does not occur on, or within 24 months after, the date of a “Change in Control” (as defined below) (a “Non-CIC Termination”) or 3, if the termination occurs on, or within the 24 months after, the date of a “Change in Control” (as defined below) (a “CIC Termination”), and (b) all of your outstanding equity awards that vest based solely on continued service will vest as of the date of termination, and all of your outstanding equity awards that vest based on achievement of performance conditions will vest either (x) pro rata, in the case of a Non-CIC Termination, or (y) in full at the target level, in the case of a CIC Termination. If your equity awards vest on a pro rata basis, the amount that vests will be determined by multiplying the ratio of actual months of employment during the performance period to the full number of months in the performance period, by the percentage of the award that is earned, based on actual performance achieved over the full performance period, with any such performance-based awards that are earned settled following completion of the applicable performance period on the normal schedule of distributions to plan participants. For clarity, a termination by the Company due to your “Disability” (as defined below) will not be treated as a termination by the Company without Cause.

For purposes of this offer letter, “Change in Control” shall mean (1) the sale (other than to a member of the Company and its predecessors, successors, and past, present and future parent companies, operating companies, divisions, subsidiaries and/or affiliates (the “Employer Group”)) of substantially all of the operating assets of the Company and its subsidiaries, (2) the acquisition (other than by a member of the Employer Group) of more than fifty percent (50%) of the stock of the Company by a group of shareholders or an entity which acquires control of the

Company, (3) a merger or consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) fifty percent (50%) or more of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or (4) during any period not longer than two (2) consecutive years, individuals who at the beginning of such period constituted the board of directors of the Company cease to constitute at least a majority thereof, unless the election, or the nomination for election by the Company’s shareholders, of each new board member was approved by a vote of at least three-fourths (3/4) of the board members then still in office who were board members at the beginning of such period (including for these purposes, new members whose election was so approved).

Termination due to Death or by the Company due to Disability. If your employment terminates due to your death or by the Company due to your “Disability,” you will not be entitled to any severance benefits other than any Accrued Obligations. For purposes of this offer letter, “Disability” means that you are unable to engage in any substantial gainful activity by reason of a physical or mental impairment that is expected to result in death or to last 6 months or more or you become eligible for long term disability payments under the Company’s applicable long term disability program.

Tax Matters

All compensation and benefits contemplated by this offer letter are subject to reduction for applicable tax withholdings and any other deductions required by law. It is intended that the terms of this offer letter comply with Section 409A of the Internal Revenue Code of 1986, as amended, and related Treasury regulations (“Section 409A”) or an exemption therefrom, and the terms of this letter agreement will be interpreted accordingly; provided, however, that the Company, and their respective affiliates, employees, officers, directors, agents and representatives (including, without limitation, legal counsel) will not have any liability to you with respect to any taxes, penalties, interest or other costs or expenses you or any related party may incur with respect to or as a result of Section 409A or for damages for failing to comply with Section 409A.

Payments pursuant to this offer letter are intended to constitute separate payments for purposes of Treasury Regulation Section l.409A-2(b)(2)(i). If any payments that are conditioned upon execution of a release within the 60-day period after termination of employment constitute deferred compensation, if the 60-day period spans calendar years the payments conditioned upon the release will be paid in the latter year. Any reimbursements or in-kind benefits provided to or for you that constitute deferred

compensation for purposes of Section 409A shall be provided in a manner that complies with Treasury Regulation Section l.409A-3(i)(l)(iv). Accordingly, (a) all such reimbursements will be made not later than the last day of the calendar year after the calendar year in which the expenses were incurred, (b) any right to such reimbursements or in-kind benefits will not be subject to liquidation or exchange for another benefit, and (c) the amount of the expenses eligible for reimbursement, or the amount of any in-kind benefit provided, during any taxable year will not affect the amount of expenses eligible for reimbursement, or the in-kind benefits provided, in any other taxable year.

Exhibit 99.1

Centuri Holdings Announces Appointment of Christian (“Chris”)

Brown as President and Chief Executive Officer

Mr. Brown Brings Deep Experience in the Energy and Infrastructure Sectors

Experienced CEO with Proven Track Record of Financial Performance through Organic Growth, M&A and Diligent Capital Allocation

PHOENIX, November 5, 2024 — Centuri Holdings, Inc. (NYSE: CTRI) (“Centuri” or the “Company”), a leading, pure-play North American utility infrastructure services company, today announced its Board of Directors has appointed Christian (“Chris”) Brown as President and Chief Executive Officer of Centuri, effective December 3, 2024. Mr. Brown will be appointed to the Centuri Board at that time. Mr. Brown succeeds Paul Caudill, who was appointed Interim President and CEO effective July 31, 2024.

Brown brings expertise in leading large, complex organizations through periods of significant evolution and growth in the energy and industrial sectors, including engineering and construction (E&C), during a career that has spanned more than three decades. Most recently, he served as CEO of EnerMech, a privately held global energy and infrastructure services company, where he developed and implemented their leading change strategy, which resulted in strong revenue growth and a differentiated service offering. Prior to this, he served as CEO of Kentz Engineers & Constructors, a FTSE 250-listed E&C business across energy, infrastructure, and utility sectors, where he was instrumental in driving a nearly sixfold increase in revenue over five years, and successfully led the company through its sale to SNC-Lavalin (now known as AtkinsRéalis), a TSX-listed E&C company. Chris has resided in Houston with his family for over 20 years.

“Throughout his impressive career, Chris has consistently demonstrated his strategic vision, operational expertise and ability to drive success and increased stakeholder value,” said Karen Haller, Chair of Centuri’s Board of Directors. “His background and experience in engineering have fostered a hands-on operational approach that has resulted in a strong technical and practical understanding of the utility sector. Across roles, his commercial acumen has led to significant growth, both organically and through tuck-in acquisitions. We look forward to benefitting from Chris’ global experience leading both publicly traded and privately held companies within the industry, and his existing relationships with some of Centuri’s customers. We are confident Chris is the ideal leader to advance our strategic initiatives and drive growth at Centuri as a world-class utility infrastructure services platform.”

“I am excited to join the team during a truly transformative period for the industry,” said Chris Brown. “Centuri stands as a leader in the utility infrastructure sector with a strong track record of safely delivering solutions across customers’ value chains. As utility companies continue to look for solutions to replace aging infrastructure and emergent technologies and clean energy initiatives grow, Centuri is well positioned to serve as a critical partner. I look forward to working with the leadership team and the Board of Directors to further identify and execute key strategic initiatives, as we capitalize on these opportunities and enhance efficiencies across the Company. As CEO, I am eager to leverage my extensive industry experience and broad-based network to support Centuri’s expanding customer base and guide the Company’s future growth trajectory.”

Ms. Haller added, “On behalf of the Board, I also want to thank Paul Caudill for his leadership and contributions as Interim CEO over the past few months. Paul provided important continuity and continued to lead strategic initiatives during a critical period for the organization. I am grateful for his leadership and his willingness to support Chris’s transition.”

About Christian Brown

Mr. Brown served as Chief Executive Officer of EnerMech, a global energy and infrastructure services company, from 2020 to 2024. During his tenure, he successfully led the company through significant operational change, creating and delivering a new global One EnerMech strategy, which included diversifying the business into new high growth end markets. From 2011 to 2015, Mr. Brown was the Chief Executive Officer and Executive Director of Kentz Engineers & Constructors, a FTSE 250 listed company. Under his leadership, Kentz’s revenues grew from $700 million to $3.9 billion, and the company was successfully sold to SNC-Lavalin in 2014. Post-acquisition, he served as President of the Oil & Gas division and Corporate Development Officer at SNC-Lavalin, where he led the $3.8 billion acquisition and integration of Atkins PLC, delivering significant cost savings and operational synergies. Earlier in his career, Mr. Brown held various senior roles at Foster Wheeler Corporation and KBR, where he managed large-scale services and projects businesses within energy and infrastructure across multiple regions, including North America, Europe, Africa, and the Middle East. His strategic leadership and business development skills were instrumental in driving growth and securing major contracts. Mr. Brown holds an MBA from Henley Management College, was awarded a Fellowship from the ECITB, and has a High National Diploma in Mechanical Engineering from the University of Hull. He is a registered Professional Engineer with the Engineering Council in the United Kingdom and a member of the Association for Project Management.
