Exhibit 99.1

|  | Key Highlights • 2Q 2026 Compensable Generation was lower than the volumes required to achieve the mid-point of FY2026 financial guidance, with the Wind and Solar segments producing approximately 5% fewer GWh than expected for the period. • Lower-than-expected YTD 2026 Compensable Generation was driven particularly by lower than typical wind resource in CAISO and ERCOT, where the measured resource was 87% and 98%, respectively, of P-50 expectations due to this year’s strong El Niño / Southern Oscillation (“ENSO”) pattern that negatively affects wind resource in the USA. • 2Q 2026 Plant Availability in the Solar and Flexible Generation segments remained high at 99% and 97%, respectively. • 2Q 2026 Plant Availability in the Wind segment remained at 92% with evolutions in regions reflecting improvement campaigns focused on highest-value assets and lower levels offset by liquidated damages paid by third party OEMs. • Compensable Generation and measured Performance Index for YTD 2026 reflect the low end of the range of quarterly CAFD Expectations for 1H26, as recently noted in the Q1 2026 earnings presentation referencing 2026 Quarterly Estimated Seasonality (and previously published in 3Q and 4Q 2025).

|  | Operating Data Preview: Notes & Disclosure July 16, 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 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 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.
