This is compared to reported EPS of $1.60 and adjusted EPS of $1.62 for the third quarter of 2024. Adjusted EPS excludes the impact of certain items that are included in reported EPS. Higher third-quarter 2025 adjusted results were driven by the implementation of new rates and riders, along with higher retail sales volumes. These items were partially offset by higher interest expense, milder weather and higher depreciation and property taxes on a growing asset base. The company is narrowing its 2025 adjusted EPS guidance range to $6.25 to $6.35 and reaffirming its long-term adjusted EPS growth rate of 5% to 7% through 2029 off the 2025 midpoint of $6.30. Management does not forecast reported GAAP EPS and related
