Represents the grant of restricted stock units ("RSUs") pursuant to the Omnibus Incentive Plan (the "Plan") of Centuri Holdings, Inc. (the "Issuer") on February 17, 2026 (the "2026 RSU Grant"). Each RSU subject to the 2026 RSU Grant is the economic equivalent of one share of the Issuer's common stock and may be settled by delivery of one share of the Issuer's common stock. | The reporting person has reported prior grants of RSUs in Table II of Form 4. The total reported in Column 5 of Table I includes the 2026 RSU Grant, 30,673 RSUs granted pursuant to the Plan and previously reported in Table II (the "Previous RSU Grants"), and 32,583 shares of common stock. As of the date of this Form 4, the Previous RSU Grants may be settled only by delivery of an equal number of shares of the Issuer's common stock. | On February 25, 2025, the reporting person was granted a total of 46,009 performance stock units pursuant to the Plan (the "2025 Performance Award"), assuming target level of achievement of the applicable performance goals. One-third of the units subject to the 2025 Performance Award were eligible to be earned based on achievement of performance goals for the fiscal year of the Issuer ended December 28, 2025 (the "First Performance Period"), and the remaining two-thirds of the units subject to the 2025 Performance Award are eligible to be earned based on achievement of performance goals for the two fiscal years of the Issuer ending January 2, 2028 (the "Second Performance Period"). | On February 17, 2026, the Issuer's board of directors certified achievement of the performance goals for the First Performance Period at 105.1% of the target level, resulting in the reporting person earning 16,111 RSUs (the "2025 Earned RSUs"). The 2025 Earned RSUs are scheduled to vest based on the reporting person's continued service through the later of February 25, 2028 and the date that the Issuer's board of directors (or a committee thereof) certifies the level of achievement of the performance goals for the Second Performance Period. | The reported transaction involved the reporting person's receipt of the 2025 Earned RSUs. The reporting person previously reported the 2025 Performance Award in Table II of Form 4. As of the date of this Form 4, the 2025 Performance Award may be settled only by delivery of a number of shares of the Issuer's common stock equal to the number of 2025 Earned RSUs plus any additional RSUs subject to the 2025 Performance Award that are earned based on the level of achievement of the performance goals for the Second Performance Period.
