424B5
Capital/Financing Update Classification · 100% confidence The document is a preliminary prospectus supplement filed pursuant to Rule 424(b)(5) related to a common stock offering by Alliant Energy Corporation. It discusses terms of the offering, underwriting details, forward sale agreements, risk factors, and regulatory disclaimers. The content is focused on capital raising activities and securities offering details, not on financial results, management changes, or other report types. The presence of terms like 'prospectus supplement', 'forward sale agreements', 'underwriters', and 'offering price' clearly indicates this is a capital/financing update document. The document length is substantial and contains detailed offering information, not just an announcement of a report publication. Therefore, the appropriate classification is Capital/Financing Update (CAP).

Board/Management Information Classification · 95% confidence The document is a Form 8-K filed with the SEC, dated December 13, 2018.

There is no financial data or report content, only management changes. According to the filing definitions, announcements of changes in the company's board or senior management fall under Board/Management Information (MANG). The document length is 6597 characters, which is sufficient for a detailed announcement but does not contain financial statements or other report types.

According to the rules, such a document announcing financial results and furnishing a press release is classified as an Earnings Release (ER).
