Knife River Corporation
A maker of construction materials, Knife River digs up aggregates—sand, gravel, and crushed stone—and turns them into ready-mix concrete, asphalt, and contracting services used on roads and buildings across 14 U.S. states. It got its start in 1917 supplying coal in North Dakota near the Knife River (its namesake), then shifted to aggregates in 1992 and spun off from parent MDU Resources in 2023 to stand on its own. Fun fact: its roots are in coal mining, a world away from the gravel yards it runs today.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: +1 shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
