  On November 22, 2023, Indianapolis Power & Light Company, doing business as AES Indiana ("AES Indiana"), a subsidiary of IPALCO Enterprises, Inc. ("IPALCO") and The AES Corporation, entered into a unanimous Stipulation and Settlement Agreement (the "Settlement") with the Indiana Office of Utility Consumer Counselor and the intervening parties in AES Indiana's pending regulatory rate review at the Indiana Utility Regulation Commission (the "IURC").
  The Settlement provides for updated base rates for electric service in AES Indiana's territory and is subject to, and conditioned upon, approval by the IURC. Among other rate matters, the Settlement, if approved, would:
  •
  Establish a revenue requirement of $1,644.7 million for AES Indiana's electric service base rates, based on a stipulated review deficiency of $73 million.
  •
  Provide for a return on common equity of 9.9%, based on a capital structure of 47.44% common equity and 52.56% long-term debt and a cost of long-term debt of 4.90%.
  •
  Establish a rate base of approximately $3.5 billion, inclusive of enhancements to customer systems that were placed into service November 2023.
  •
  Provide increased funding for vegetation management, and recovery of investments in reliability and resiliency improvements, customer systems and increased labor and other operational costs.
  A hearing at the IURC on the Settlement is currently scheduled in December 2023, and AES Indiana anticipates an order from the IURC in the second quarter of 2024. AES Indiana's rate review case docket, which will include a copy of the Settlement, is available through the IURC's online portal at
