Item 1.01 Entry Into a Material Definitive Agreement.

Underwritten Offering

On November 12, 2025, Centuri Holdings, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC (“J.P. Morgan”) and Wells Fargo Securities, LLC, as representatives of the several underwriters named therein (collectively, the “Underwriters”), pursuant to which the Company agreed to issue and sell 7,441,860 shares of its common stock, par value $0.01 per share (“Common Stock”), to the Underwriters (the “Offering”). The price to the public in the Offering was $21.50 per share (the “Offering Price”). In addition, under the terms of the Underwriting Agreement, the Company granted the Underwriters the option, for 30 days after the date of the prospectus supplement specifically relating to the Offering (the “Prospectus Supplement”), to purchase up to 1,116,279 additional shares of Common Stock at the Offering Price, less underwriting discounts and commissions.

The Offering was made under the Prospectus Supplement and related prospectus filed with the Securities and Exchange Commission (the “SEC”) pursuant to the Company’s effective shelf registration statement on Form S-3, as amended (Registration No. 333-287200).

Under the terms of the Underwriting Agreement and pursuant to a lock-up agreement, the Company, the Company’s directors and executive officers, the Icahn Investors (as defined below) and certain of their respective affiliates also agreed not to sell or transfer any Common Stock without first obtaining the written consent of J.P. Morgan, subject to certain exceptions, for 30 days after the date of the Prospectus Supplement.

The Offering is not contingent upon the Concurrent Private Placement (as defined below) and is expected to close on November 14, 2025. The Company intends to use the net proceeds from the Offering and the Concurrent Private Placement for general corporate purposes, which may include, among other things, the funding of acquisitions and the repayment of borrowings outstanding under its current credit agreement.

The Underwriting Agreement contains customary representations, warranties, covenants, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), and other obligations of the parties. The representations, warranties and covenants contained in the Underwriting 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. A copy of the Underwriting Agreement is filed as Exhibit 1.1 hereto and is incorporated herein by reference.

Concurrent Private Placement

Icahn (collectively, the “Icahn Investors”), pursuant to which the Company agreed to issue and sell approximately $75 million of shares of Common Stock (the “Private Placement Shares”) to the Icahn Investors at a price per share equal to the Offering Price in a transaction exempt from registration under the Securities Act (the “Concurrent Private Placement”). The Concurrent Private Placement is expected to close immediately following the closing of the Offering and is subject to the satisfaction or waiver of customary closing conditions, including the completion of the Offering.

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. A copy of the Private Placement Agreement is filed as Exhibit 10.1 hereto and is incorporated herein by reference. The foregoing

description of the Private Placement Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.

Pursuant to the Icahn Letter Agreement, 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 the Concurrent 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.

A copy of the Icahn Letter Agreement is filed as Exhibit 10.2 hereto and is incorporated herein by reference. The foregoing description of the Icahn Letter Agreement does not purport to be complete and is qualified in its entirety by reference to such exhibit.
