<div align='center'>2022-2024 GHG Reduction Metric Achievement Calculation</div>

Performance Update for the 2023-2025 Quantitative Component

The target cumulative MW change is 2,526 MW for the 2023-2025 performance period. Through the end of 2024, the Company forecasts below target achievement for the 2023-2025 performance period based on solar generation that is not forecast to be in operation during the performance period due to supply chain and economic challenges and anticipated extensions of the retirement dates for certain coal and gas steam generation units due to unanticipated projected load growth in our service territories primarily associated with unprecedented projected economic expansion.

#### 2025-2027 GHG Reduction Metric
Based on feedback received from stockholders during 2024 supporting this metric, the Committee included the GHG Reduction Metric as part of the LTI award of the CEO, CFO and COO for the 2025-2027 performance period. We will continue to seek feedback from stockholders during 2025 on this metric.
