Mong Duong — In November 2023, the Company entered into an agreement to sell its entire 51% ownership interest in Mong Duong 2, a coal-fired plant in Vietnam, and 51% equity interest in Mong Duong Finance Holdings B.V., an SPV accounted for as an equity affiliate (collectively "Mong Duong"). The carrying amount of the Mong Duong disposal group, which primarily consisted of our loan receivable from the sale of the power plant to the Vietnamese government, in subsequent periods exceeded the expected sales proceeds and as a result, the Company recognized pre-tax impairment expense of $43 million during the six months ended June 30, 2024, and $17 million during the three months ended March 31, 2025. As of May 31, 2025, due to delays in closing the transaction and the pending expiration of the agreement in November 2025, the Company determined Mong Duong no longer met the held-for-sale criteria. As such, the Mong Duong asset group was reclassified as held and used. The loan receivable was remeasured at amortized cost and non-loan assets were each individually remeasured at the lower of (i) carrying value before being classified as held for sale, adjusted for any depreciation expense or impairment losses that would have been recognized had the assets been continuously classified as held and used, or (ii) fair value at the date of the subsequent determination that held-for-sale criteria was no longer met. As a result, the Company recorded a $243 million increase in the carrying value of the Mong Duong asset group due to the derecognition of a $239 million valuation allowance on the loan receivable accounted for under ASC 310, which had been recognized in Asset impairment expense between December 31, 2023 and March 31, 2025 while Mong Duong was classified as held-for-sale, and the elimination of $4 million in net estimated costs to sell from the measurement of the asset group. See Note 18—Held-for-Sale and Dispositions for further information. Mong Duong is reported in the Energy Infrastructure SBU reportable segment. AES Clean Energy Development Projects — AES Clean Energy Development has a pipeline of U.S. renewables projects that are in various stages of development and construction. In some cases, if development efforts are not successful, the Company may abandon a particular project, writing off all the intangible assets and capitalized development costs incurred. The fair value of each abandoned project with no salvage value is determined to be zero as there are no future projected cash flows. The Company recognized $117 million and $14 million of pre-tax asset impairment expense related to the write-off of projects that were determined to be no longer viable during the six months ended June 30, 2025 and 2024, respectively. Of the $86 million pre-tax asset impairment expense recorded during the three months ended June 30, 2025, $51 million was related to right sizing our development company as part of the restructuring program initiated in February 2025. See Note 21—Restructuring for further information. AES Clean Energy Development is reported in the Renewables SBU reportable segment. AES Brasil — In May 2024, the Company entered into an agreement to sell its 47.3% controlling interest in AES Brasil, a 5.2 GW portfolio of renewable energy facilities. Upon meeting the held-for-sale criteria in May 2024, the Company performed an impairment analysis and determined that the carrying value of the disposal group of $1,577 million was greater than its fair value less costs to sell of $1,552 million. As a result, the Company recognized pre-tax impairment expense of $25 million. The sale of AES Brasil closed in October 2024. Prior to its sale, AES Brasil was reported in the Renewables SBU reportable segment.
