Full insider history for Alliant Energy Corporation Common Stock, or insider activity across all companies. A record of filings, not a recommendation.
Sources
Fiscal year ends in month 12; periods are labeled with the issuer's own fiscal calendar. Values are as most recently filed (restatements apply; per-share values are on current split basis per the connector's split table, flagged in adjusted). Flow items flagged in `derived` were computed (Q4 = FY − nine months; quarterly cash flow differenced from year-to-date filings) rather than read from a filing. `reconciliation.repaired` lists periods where a full-year figure was filed in a quarter slot: that row was dropped and the quarter rebuilt from the annual figure. `reconciliation.quarantined` lists periods where four filed quarters do not sum to the filed year — those quarterly values are withheld, so a blank there is a withholding rather than an absence of reporting.
