Solar resource was slightly below P-50 in the Western US. • 3Q 2026 Plant Availability in the Solar and Flexible Generation segments remained high at 97% and 94%, respectively. Plant Availability for 3Q 2026 in the Wind segment reflected improvement campaigns focused on highest-value assets in CAISO and Texas, while Midwest Wind and East Wind availability were driven by small projects using discontinued wind OEM technology, which are being addressed through an active improvement campaign.

Operating Data Preview: Notes & Disclosure October 20, 2026 Notes to Operating Data Preview 1) All metrics exclude equity method investment projects (San Juan Mesa, Elkhorn Ridge, Avenal, Desert Sunlight, and Cardinal Fengate JV) 2) “Flexible Generation” represents Equivalent Availability Factor (“EAF”) in the Plant Availability section 3) “Plant Availability” is weighted by the Net Capacity MW in the given region or technology. 4) Performance Index is weighted based on volume-related revenue assumed in the original guidance mid-point 5) “Compensable Generation” is the quantity of GWh for which a plant is compensated and is the sum of physically generated electricity plus electricity that could have been generated and is subject to compensation under customer or supplier agreements. 6) “Performance Index” is Compensable Generation as defined above, divided by generation assumed in the original guidance mid-point Safe Harbor Disclosure • This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
