PWRQuanta Services · Insider ownership research

Quanta Services insiders sold $138M in the past 12 months. How much of their stake is that?

About 8.7% overall. As a group they ended with more shares than they started with. These figures leave out Earl Austin Jr., the largest holder (holdings couldn't be fully reconciled).

No officer or director trades were reported for the past 30 days. The most recent before that:

May 11, 2026Martha Wyrsch gave away 2.5K shares as a gift. That is 33% of the total stake held that day.

"% of total stake" is the shares in this 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 don't reconcile, 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.

Is this normal? Less than usual: about two-thirds of the 5-year average. 6 insiders sold; the average is 7 a year. Year by year

What stands out

Four insiders sold more than 25% of vested holdings: Donald Wayne (29% of holdings, $6.2M, none under a disclosed plan), Gerald Ducey Jr. (28% of holdings, $3.4M, none under a disclosed plan) and Paul Nobel (40% of holdings, $3.0M, none under a disclosed plan), plus 1 more.Donald Wayne: largest sale, Nov 6, 2025 · Gerald Ducey Jr.: largest sale, Nov 6, 2025 · Paul Nobel: largest sale, May 4, 2026
Two insiders sold $122M with no disclosed plan: Earl Austin Jr. ($120M) and Bernard Fried ($1.8M, 19% of holdings). The filings don't state a reason.Earl Austin Jr.: largest such sale, May 5, 2026 · Bernard Fried: largest such sale, Nov 3, 2025
Bernard Fried sold 4K shares (19% of starting holdings), but 5.4K more vested, so the stake grew (from 21K to 23K).Largest sale, Nov 3, 2025

Percentages cover 15 of 18 officers and directors. Left out: Earl Austin Jr. (holdings couldn't be fully reconciled); Joseph Kim and Ellen Rubin (held no vested shares at the start). Disclosed company stock is not an insider's whole wealth.

Common questions

Is the Quanta Services CEO selling stock?

Yes. Earl Austin Jr. sold 156K shares ($120M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Quanta Services 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% had no disclosed plan. A trading plan schedules sales in advance.

Are any Quanta Services insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Quanta Services insiders sell?

About 8.7% overall. As a group they ended with more shares than they started with. These figures leave out Earl Austin Jr., the largest holder (holdings couldn't be fully reconciled). That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

17 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (17 exactly, 0 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 15 of 18 officers and directors. Left out: Earl Austin Jr. (holdings couldn't be fully reconciled); Joseph Kim and Ellen Rubin (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$138M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $138M across 191,994 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $138M

Sales with no 10b5-1 plan and no tax reference in the filing. $120M of it is Earl Austin Jr.. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Earl Austin Jr., May 5, 2026

Taxes

69,476 shares ($39.0M) were withheld by the company for taxes, which isn't a market sale.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty1 insider whose holdings couldn't be fully reconciled

Earl Austin Jr.: holdings couldn't be fully reconciled (difference of 20,000 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +42,500 shares on May 5, 2026 (C4M3, LLC). Filing, May 5, 2026

Footnote: "The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $765.00 to $765.997. The reporting person undertakes to provide to Quanta Services, Inc., any security holder of Quanta Services, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this and the following footnotes."

Inferred typo: the share class "Coomon Stock" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Dale Querrey, 48,050 shares): old title, new title

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology1,246 filings from SEC EDGAR, and how we read them

All 1,246 Forms 3, 4 and 5 filed for Quanta Services (SEC CIK 1050915) from Sep 9, 1998 to Sep 11, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 74 older filings exist only on paper and could not be read.

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".
