BUSINESS SEGMENTS

IPALCO manages its business through one reportable operating segment, the Utility segment. The primary segment performance measure is income / (loss) before income tax as management has concluded that this measure best reflects the underlying business performance of IPALCO and is the most relevant measure considered in IPALCO’s internal evaluation of the financial performance of its segment. The Utility segment is comprised of AES Indiana, a vertically integrated electric utility. with all other nonutility business activities aggregated separately. The “Other” nonutility category primarily includes the 2024 IPALCO Notes, 2030 IPALCO Notes, 2034 IPALCO Notes and related interest expense, balances associated with IPALCO’s interest rate hedges, cash and other immaterial balances. The accounting policies of the identified segment are consistent with those policies and procedures described in the summary of significant accounting policies. See Note 1, "Overview and Summary of Significant Accounting Policies" to IPALCO’s 2023 Form 10-K for further information.
