Sales by month

More than usual: about 2.5x the 5-year average. 4 insiders sold; the average is 4 a year.

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.

All 936 Forms 3, 4 and 5 on record for Mueller Industries Inc (SEC CIK 89439), filed from Apr 8, 2002 to Aug 27, 2026; 34 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. 5 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before May 1, 2014 (first filing that shows post-split balances). Splits aren't reported as transactions; 13 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 2-for-1 stock split on or before Oct 20, 2023 (split date stated in a footnote). Splits aren't reported as transactions; 14 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 2-for-1 stock split on or before Jun 30, 2026 (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".
