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.

"Since last quarter, we have completed two additional accretive revenue contracts in our Texas operating fleet, received a dropdown offer for Honeycomb Phase II, and our sponsor has secured over 2 GW of new contracts recently signed for the 2027-2030 COD vintages, further crystallizing our long-term financial objectives. We remain in a very solid position to continue to strive for the top end or better of our CAFD per share target for 2030 of $2.90 to $3.10, we have line of sight now to the potential for 5-8%+ growth beyond 2030 from our 2030 target baseline, and continue to have the ability to generate further potential upside across all of our growth pathways, including through our co-located digital infrastructure business as it takes shape. With the building blocks needed to fulfill our growth objectives increasingly in view, we are well positioned to maximize value for CWEN stockholders over the long term.

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).
