Mdu Resources Group, Inc.
A regulated energy delivery company in the northern U.S., MDU Resources delivers electricity and natural gas and runs pipelines through brands like Montana-Dakota and WBI Energy, serving homes and businesses across several states. It began in 1924 as a small electric utility founded by Rolland Heskett along the Montana–North Dakota border, and the initials "MDU" simply stand for Montana-Dakota Utilities. In 2024 it spun off its construction business to focus purely on utilities, keeping its 1920s roots in the prairie.

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 year: +10.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
