Guarantee amount shown represents guarantees issued on behalf of the Clean Energy Businesses that remain outstanding at September 30, 2023.

Pursuant to the purchase and sale agreement, RWE is obligated to reimburse and hold harmless Con Edison for any payments Con Edison makes under guarantees issued by Con Edison on behalf of the Clean Energy Businesses. As of September 30, 2023, no such payments have been, or are probable of being, made.
