"% of total stake" is the shares in an event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings are not confirmed, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Outside holders, reported separately

Carl Icahn and Southwest Gas Holdings, Inc. reported no open-market sales in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.

Details

Common questions

Is the Centuri Holdings, Inc. CEO selling stock?

Yes. Christian Brown sold 7.1K shares ($174K) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Centuri Holdings, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% were to cover taxes. A trading plan schedules sales in advance.

Are any Centuri Holdings, Inc. insiders buying?

Yes. 1 officer or director reported 1 purchase in the past 12 months (Form 4 code P; rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust are not counted).

Sources and methodology97 filings on record, 33 filed in the 12-month period, and how we read them

All 97 Forms 3, 4 and 5 on record for Centuri Holdings, Inc. (SEC CIK 1981599), filed from Apr 17, 2024 to Sep 21, 2026; 33 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
