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

Feb 17, 20266 executives had 9.7K shares ($1.3M) withheld by the company for taxes (not a market sale). That is between 3.2% and 9.9% of each person's total stake held that day. 45K shares came in from vesting or option exercises the same day, so their combined holdings rose by 35K net.

"% 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: no sales, against a 5-year average of 9.8K shares a year. 0 insiders sold; the average is 2 a year. Year by year

16 of 16 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (11 exactly, 5 with a minor or footnoted difference). Percentages cover all 16 officers and directors. "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

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.

Inferred typo: the share class "Common Stck" 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 (Martha Goss, 22,871 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 methodology921 filings from SEC EDGAR, and how we read them

All 921 Forms 3, 4 and 5 filed for American Water Works (SEC CIK 1410636) from Apr 22, 2008 to May 13, 2026, retrieved from SEC EDGAR on Oct 8, 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".
