Alliant Energy Corp

Could not find a ticker for this position, may be a filing error

A regulated utility holding company that delivers electricity and natural gas to roughly a million and a half homes and businesses across Iowa and Wisconsin through its two main units, Interstate Power and Light and Wisconsin Power and Light. The company was born in 1998 when three regional utilities merged, and it took the name "Alliant" the next year as a play on "alliance" — a nod to the three-way partnership that created it. Its roots stretch back to utilities incorporated in the 1920s, and it also holds a stake in a transmission-only company and a wind farm in Oklahoma.

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.
