Goodwill, net
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 third quarter of 2023, due to the continued material sustained decline in the Company’s market capitalization after consideration of a control premium below the book value of equity, the Company performed an interim quantitative assessment as of September 30, 2023 related to the recoverability of its goodwill for its one reporting unit. 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 were no such impairments during the years ended December 31, 2022 and 2021. As of October 1, 2023, the Company conducted its annual goodwill impairment test. The test concluded that no additional impairment had occurred during the fourth quarter of 2023. To corroborate this conclusion, the Company compared the carrying value of its one reporting unit to its enterprise market capitalization after consideration of a reasonable control premium and concluded that there was no goodwill impairment during the fourth quarter of 2023.
The change in the carrying value of goodwill is as follows (in millions):

Balance—January 1, 2023, 2022 and 2021
$4,280 
Impairment—September 30, 2023
(1,158)
Balance—December 31, 2023$3,122

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
