Item 5.02
Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On March 20, 2026, the Board of Directors (the “Board”) of Centuri Holdings, Inc. (the “Company”) approved an increase in the size of the Board from eight to nine members and elected Mr. Steven E. Nielsen to fill the vacancy created by such increase, effective immediately.

Mr. Nielsen spent 31 years at Dycom Industries, Inc. (NYSE: DY) (“Dycom”), most recently as Chairman of the Board between 2000 and 2024, and President and Chief Executive Officer from March 1999 to 2024. While there he led Dycom through 25 years of transformational growth, scaling the business from under $200 million in revenue to more than $4.5 billion. He was also previously a director of SBA Communications Corporation (Nasdaq: SBAC). Mr. Nielsen received a Bachelor of Arts degree from Williams College in 1985.

At this time, Mr. Nielsen has not been appointed to serve on any committee of the Board. Mr. Nielsen will receive the same compensation that the other directors who are not employees of the Company receive for Board membership, as described in the Company’s definitive proxy statement filed with the U.S. Securities and Exchange Commission on March 5, 2025.

There are no arrangements or understandings between Mr. Nielsen and any other persons, pursuant to which Mr. Nielsen was selected as a director of the Company, and there are no transactions between Mr. Nielsen and the Company that would be reportable under Item 404(a) of Regulation S-K.

As a result of the increase in the size of the Board from eight to nine members, the deadline for receipt of director nominations submitted pursuant to the Company’s Amended and Restated Bylaws (the “Bylaws”) for consideration at the Company’s 2026 Annual Meeting of Stockholders has been extended to the close of business on March 30, 2026, but only with respect to nominations for the new position created by the Board size increase. For information on how to submit any such director nomination, stockholders are urged to read the complete text of the advance notice and other provisions of the Bylaws and the section titled “Stockholder Proposals For The 2026 Annual Meeting” in the Company’s Proxy Statement for the 2025 Annual Meeting of Stockholders.

Item 7.01
Regulation FD Disclosure.

On March 20, 2026, the Company issued a press release announcing the appointment of Steven E. Nielsen to the Board. A copy of the press release is furnished hereto as Exhibit 99.1.

The information disclosed under this Item 7.01, including Exhibit 99.1 hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and shall not be deemed incorporated by reference into any filing made under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.
