"% 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? In line with the past 5 years. 9 insiders sold; the average is 5 a year. Year by year

What stands out

Steven Schwarzwaelder sold 26% of vested holdings: 5.6K shares for $5.0M, none under a disclosed plan.Largest sale, Apr 30, 2026
Three insiders sold $6.6M with no disclosed plan: Maxine Mauricio ($2.5M, 12% of holdings), John Altmeyer ($2.2M, 6.9%) and William Reid ($1.9M, 16%). The filings don't state a reason.Maxine Mauricio: largest such sale, Mar 2, 2026 · John Altmeyer: largest such sale, May 1, 2026 · William Reid: largest such sale, May 11, 2026

Percentages cover 12 of 13 officers and directors. Left out: Patrick Roche (held no vested shares at the start). Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the Emcor|| Industrials CEO selling stock?

Yes. Anthony Guzzi sold 36K shares ($26.3M, 17% of starting holdings) in the past 12 months, all of it under a trading plan disclosed in the filings.

Why are Emcor|| Industrials insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 64% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 36% had no disclosed plan. A trading plan schedules sales in advance.

Are any Emcor|| Industrials insiders buying?

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

How much of their stake did Emcor|| Industrials insiders sell?

About 14% overall. As a group they still hold 85% of their starting shares. That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

13 of 13 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (13 exactly, 0 with a minor or footnoted difference). Percentages cover 12 of 13 officers and directors. Left out: Patrick Roche (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$40.8M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $40.8M across 53,209 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

The lighter segment is sales with no plan disclosed in the filing ($14.6M), including tax-related sales outside a plan.

No plan disclosed · $14.6M

Sales with no 10b5-1 plan and no tax reference in the filing. $5.0M of it is Steven Schwarzwaelder. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Steven Schwarzwaelder, Apr 30, 2026

Taxes

11,228 shares ($8.1M) 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 uncertaintyEvery officer and director reconciles

Every officer and director reconciles for this period.

Inferred rename: "ByJerry E. Ryan Recovable Trust" is treated as the same holder as "Jerry E. Ryan Recovable Trust", because the old name was never reported again and the new one opened with the same balance (44,000 shares). Old name, new name

Inferred typo: the share class "CommonStock" 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 (Frank Macinnis, 389,561 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 methodology1,789 filings from SEC EDGAR, and how we read them

All 1,789 Forms 3, 4 and 5 filed for Emcor|| Industrials (SEC CIK 105634) from Oct 14, 1998 to Aug 3, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 5 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before Feb 10, 2006 (split date stated in a footnote). Splits aren't reported as transactions; 12 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 2-for-1 stock split on or before Jul 9, 2007 (split date stated in a footnote). Splits aren't reported as transactions; 10 holding lines changed by exactly this ratio, so earlier share counts are restated.

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".
