PRINCETON, NJ — August 5, 2026— Clearway Energy, Inc. (NYSE: CWEN) today reported second quarter 2026 financial results, including Net Income of $30 million, Adjusted EBITDA of $409 million, Cash from Operating Activities of $214 million, and Cash Available for Distribution (CAFD) of $167 million.

"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. While we are lowering our 2026 financial guidance due to factors outlined in our mid-July operational preview, our team is focused on maintaining our trademark operational excellence to uphold our historic track record of meeting our financial targets," said Craig Cornelius, Clearway Energy, Inc.'s President and Chief Executive Officer.

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).

PRINCETON, NJ — May 7, 2026— Clearway Energy, Inc. (NYSE: CWEN, CWEN.A) today reported first quarter 2026 financial results, including Net Loss of $68 million, Adjusted EBITDA of $257 million, Cash from Operating Activities of $401 million, and Cash Available for Distribution (CAFD) of $70 million.

“Our diversified fleet remains on track to deliver on our financial guidance for the year. Looking further out, we have increased the total corporate capital investment opportunities we are targeting through 2029 by 20% since last November, demonstrating substantial progress and potential upside to the long-term financial objectives we have set for our business. This progress now increases our enterprise’s total late-stage opportunity pipeline to 12.7 GW. With all these advancements, we are in a very solid position to continue to strive for the top end or better of our $2.90 to $3.10 CAFD per share target for 2030. We also continue to be optimistic about our ability to grow CAFD per share 5–8%+ in the years beyond 2030, including growing at the top end of that range in 2031 from our 2030 target baseline, with potential upside from the co-located digital infrastructure growth pathway. Finally, stockholder approval of a simplified share structure will now benefit all holders with a more liquid investment, greater attractiveness to a broader investor base, and additional flexibility to support our capital allocation strategy,” said Craig Cornelius, Chief Executive Officer of Clearway Energy, Inc.
