The goodwill was acquired as part of the acquisition of Mainstream Energy Corporation, which included AEE Solar and its racking business SnapNrack; Clean Energy Experts, LLC; Omni Energy, LLC; and Vivint Solar.
The Company has determined that it has one reporting unit and performs its annual impairment test of goodwill on October 1 of each fiscal year or whenever events or circumstances change or occur that would indicate that goodwill might be impaired. During the fourth quarter of 2024, the Company as part of its annual impairment test performed a qualitative assessment as of October 1, 2024 related to the recoverability of its goodwill for its one reporting unit. As of October 1, 2024, the Company concluded that the fair value of the Company’s one reporting unit exceed its carrying value with consideration of a reasonable control premium. However, during the fourth quarter of fiscal 2024, the Company performed an interim quantitative assessment as of December 31, 2024 related to the recoverability of its goodwill for its one reporting unit as a result of a material sustained decline in the Company’s market capitalization below the book value of equity. The Company concluded that the fair value of its one reporting unit did not exceed its carrying value as of December 31, 2024 and recorded a non-cash goodwill impairment charge of $3.1 billion in its consolidated statements of operations. As of September 30, 2023, the Company concluded that the fair value of the Company’s one reporting unit did not exceed its carrying value with consideration of a control premium and recorded a non-cash goodwill impairment charge of $1.2 billion in its consolidated statements of operations. There was no such impairment during the year ended December 31, 2022.
