Alliant Energy is offering fixed-to-fixed reset rate junior subordinated notes described in this prospectus supplement. The notes permit the company to optionally defer interest payments (subject to specified timing and restrictions), and any deferred interest will accrue additional interest at the then-applicable rate to the extent permitted by law. As of June 30, 2025, Alliant Energy reported $11,015 million of consolidated indebtedness (net of unamortized costs), no secured debt, and $550 million of undrawn capacity under its single revolving credit facility. Its subsidiaries had approximately $15,472 million of indebtedness and other liabilities to third parties to which the notes would be structurally subordinated. After giving effect to the issuance and use of proceeds, consolidated indebtedness would have been $11,740 million. The company expects the notes to be treated as variable rate debt instruments for U.S. federal income tax purposes but warns that if the deferral option is not considered remote or is exercised, the notes could be treated as issued with original issue discount, with related tax consequences for U.S. holders.
Alliant Energy Corporation has filed a post‑effective amendment to its shelf registration statement on Form S‑3 to add junior subordinated debt securities as a new class of securities that may be issued. Under this shelf, Alliant Energy may from time to time offer common stock, senior or subordinated debt, warrants, stock purchase contracts and stock purchase units, while certain shareowners may separately resell common stock using related prospectus supplements. The base prospectus explains that net proceeds from any primary offerings will generally be used for corporate purposes such as debt repayment, capital spending, investments, working capital and potential security repurchases, with specific terms and pricing to be set in future supplements.

Alliant Energy Corporation (LNT) – Form 4 filing
Director Ignacio A. Cortina reported the grant of 759 Deferred Common Stock Units on 11 July 2025 under transaction code “A” (award). Each unit represents the right to receive one share of LNT common stock upon the director’s departure from the board. The filing lists an indicative reference price of $62.08 and brings Cortina’s total deferred stock balance to 7,916.756 units, which already reflects automatic dividend reinvestment adjustments permitted under Rule 16a-11.
The award appears to be routine board compensation rather than an open-market purchase or sale; therefore, the transaction has no direct cash outlay by the director and limited immediate impact on float or insider sentiment.
Alliant Energy Corporation (LNT) – Form 4 insider transaction
Director Stephanie Cox reported the grant of 1,168 deferred common stock units on 11 July 2025. The award is coded “A”, indicating an acquisition under the company’s non-derivative compensation plan rather than an open-market purchase. Each unit is economically equivalent to one share of common stock and is settled in stock when the director leaves the board. The filing lists a reference price of $62.08, implying an award value of roughly $72.5 k. Following the transaction, Cox’s total holdings in this plan rise to 14,663.069 units, enhancing her equity exposure and alignment with shareholder interests.
- No shares were sold; ownership remains recorded as direct (D).
- The increase is part of routine director compensation; no 10b5-1 plan was indicated.
- The filing does not include additional financial results or operational disclosures.
