Alliant Energy 8-K Report, Material Agreement (Mar 3, 2025)

On March 3, 2025, Alliant Energy Finance, LLC (AEF), a wholly-owned subsidiary of Alliant Energy Corporation, entered into a one-year second amended and restated term loan credit agreement with U.S. Bank National Association, as administrative agent, and the several lenders party thereto.

The initial principal amount available is $300 million^a, maturing March 2, 2026, with an incremental term loan facility of up to $100 million, though no lender is obligated to provide it. Alliant Energy guaranteed AEF's obligations under the agreement. Proceeds will be used to refinance existing AEF indebtedness and for general corporate purposes.

The agreement amends and restates the existing term loan credit agreement. The Credit Agreement includes several covenants that investors should note. Alliant Energy must maintain a consolidated debt-to-capital ratio of not greater than 65%^b.

The agreement restricts liens on property of AEF, Alliant Energy and its subsidiaries, subject to exceptions such as liens securing obligations of up to 10% of consolidated assets and up to $100 million^c of non-recourse debt at each of Interstate Power and Light Company and Wisconsin Power and Light Company, plus $100 million at non-utility subsidiaries. It also requires that asset sale proceeds above 25% of consolidated assets, with certain exclusions, be used to reduce certain debt commitments during the term. The agreement contains customary events of default, including a cross-default triggered by a default on debt (excluding non-recourse debt) of $100 million or more by Alliant Energy or its domestic subsidiaries.

Upon an uncured event of default, lenders may accelerate outstanding obligations, and a bankruptcy order for relief against AEF or Alliant Energy would make obligations immediately due. The full terms are described in Exhibit 10.1, the Credit Agreement, which is incorporated by reference.
