  Item 1.01     Entry into a Material Definitive Agreement.
  On March 7, 2024, the principal subsidiary of IPALCO Enterprises, Inc. ("IPALCO"), Indiana Power & Light Company, d/b/a AES Indiana ("AES Indiana") entered into a purchase agreement (the "AES Indiana Purchase Agreement") with J.P. Morgan Securities LLC, PNC Capital Markets LLC and U.S. Bancorp Investments, Inc., as representatives (collectively, the "Representatives") of the several initial purchasers named therein (the "AES Indiana Initial Purchasers"), relating to the previously announced offering by AES Indiana of $650 million aggregate principal amount of First Mortgage Bonds (the "Bonds") at an annual interest rate of 5.700%. AES Indiana intends to use the net proceeds from the Bonds to repay amounts outstanding under its unsecured $300.0 million term loan agreement that matures on November 19, 2024 and to repay amounts due under its $350.0 million revolving credit agreement that matures on December 22, 2027. Any remaining net proceeds will be used for general corporate purposes.
  The Bonds will be secured by the lien of the mortgage which constitutes a valid, direct first mortgage lien upon AES Indiana's interest in substantially all the property now owned by it and specifically described in the mortgage as subject to the lien of the mortgage which has not been released by the trustee or otherwise retired pursuant to the terms of the mortgage, subject to certain exceptions. The Bonds will rank equally in right of payment with AES Indiana's other existing or future First Mortgage Bonds issued under the mortgage. The AES Indiana Purchase Agreement contains customary representations, warranties and covenants by AES Indiana together with customary closing conditions. Under the terms of the AES Indiana Purchase Agreement, AES Indiana has agreed to indemnify the AES Indiana Initial Purchasers against certain liabilities. The offering of the Bonds is expected to close on or about March 18, 2024, in accordance with the terms of the AES Indiana Purchase Agreement.
  In addition, on March 8, 2024, IPALCO entered into a purchase agreement (the "IPALCO Purchase Agreement") with the Representatives, as representatives of the several initial purchasers named therein (the "IPALCO Initial Purchasers"), relating to the sale by IPALCO of $400 million aggregate principal amount of senior secured notes (the "Notes") at an annual interest rate of 5.750%. IPALCO intends to use the net proceeds from the sale of the Notes, together with cash on hand, to finance its repurchase or redemption of its outstanding 3.70% Senior Secured Notes due 2024, of which $405 million is currently outstanding.
  The Notes will be secured through a pledge by IPALCO of all the outstanding common stock of AES Indiana. The Notes will effectively rank junior to the liabilities of IPALCO's subsidiaries. The IPALCO Purchase Agreement contains customary representations, warranties and covenants by IPALCO together with customary closing conditions. Under the terms of the IPALCO Purchase Agreement, IPALCO has agreed to indemnify the IPALCO Initial Purchasers against certain liabilities. The offering of the Notes is expected to close on or about March 14, 2024, in accordance with the terms of the IPALCO Purchase Agreement.
