(1)CenterPoint Energy’s higher effective tax rate for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 was primarily driven by the impact of the non-deductible goodwill associated with the sale of the Louisiana and Mississippi natural gas LDC businesses. For additional detail, see Note 3. (2)Houston Electric’s lower effective tax rate for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 was primarily driven by a decrease in state income taxes. (3)CERC’s higher effective tax rate for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 was primarily driven by the impact of the non-deductible goodwill associated with the sale of the Louisiana and Mississippi natural gas LDC businesses on March 31, 2025 and the absence of impacts associated with the state deferred tax remeasurement and valuation allowance related to the Louisiana and Mississippi natural gas LDC businesses recorded in 2024 upon classification as held for sale.
