Common questions

Is the Zurn Elkay Water Solutions Corp CEO selling stock?

Yes. Todd Adams sold 538K shares ($28.1M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Zurn Elkay Water Solutions Corp insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 3% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 47% were to cover taxes and 51% had no disclosed plan. A trading plan schedules sales in advance.

Are any Zurn Elkay Water Solutions Corp 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).

What explains the selling$38.9M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $38.9M across 750,787 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $1.0M · 3%

97%

The lighter segment is sales with no plan disclosed in the filing ($37.9M), including tax-related sales outside a plan.

No plan disclosed · $19.7M

Sales with no 10b5-1 plan and no tax reference in the filing. $14.0M of it is Todd Adams. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Todd Adams, Feb 10, 2026

Taxes

$18.3M of sales (46.9%) cite tax obligations in their footnotes. Example: Jeffrey LaValle, Feb 17, 2026

Purchases · 1 buyer (1 trade)

1 officer or director bought shares in this period, in 1 trade(Form 4 code P, leaving out rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust). Across all their filings on record there are 8 purchase trades.

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 uncertainty21 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Zurn Elkay Water Solutions Corp are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

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

Sources and methodology807 filings on record, 62 filed in the 12-month period, and how we read them

All 807 Forms 3, 4 and 5 on record for Zurn Elkay Water Solutions Corp (SEC CIK 1439288), filed from Mar 28, 2012 to Aug 21, 2026; 62 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages. 2 filings were left out because Zurn Elkay Water Solutions Corp filed them as an owner of another company's stock.

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".
