Source: XBRL data Alliant Energy Corporation files with the SEC, latest filing dated May 1, 2026 (see filings on SEC EDGAR). Provided for information only, not investment advice. Check the filing before relying on a number.
* Worked out from the filings rather than stated in them: Q4 is the full year less the first nine months.
Per-share figures and share counts are restated for stock splits the filings show: 2-for-1, first reported Aug 2, 2016.
EPS growth is left out where the share count moved enough to suggest a split the filings do not show. Growth rates need a positive starting figure. CAGR is compound annual growth between fiscal years. The CSV holds every period on file, in full figures, from the same SEC filings.
