At December 31, 2024 and December 31, 2023, the Renewables Segment had inventories with carrying amounts exceeding their net realizable value, which is estimated using indicative market pricing available at the time the estimate was made. As a result, we recognized losses of $5 million and $4 million in Cost of materials and other in the Company’s Consolidated Statements of Operations for the years ended December 31, 2024 and 2023, respectively, to reflect the net realizable value of such inventories. No adjustment was necessary for the year ended December 31, 2022.
