As of June 30, 2026, the aggregate carrying value of goodwill was $135.2 million, all attributable to the Array Legacy Operations segment, net of cumulative impairments of $51.9 million. There were no changes in the carrying amount of goodwill by segment during six months ended June 30, 2026.

The Company tests goodwill for impairment annually or more frequently if facts or circumstances indicate that it is more likely than not that the fair value of its reporting units is less than its carrying value, which would require the Company to perform an interim goodwill impairment test. The Company did not identify any indicators of impairment as of June 30, 2026.

The Company assesses long-lived assets classified as “held and used,” including property, plant and equipment, lease assets and intangible assets for impairment whenever events or changes in circumstances arise, including consideration of technological obsolescence, that may indicate that the carrying amount of such assets may not be recoverable.

As of June 30, 2026, no events or circumstances were noted that would indicate that the carrying amount of any of Array Legacy Operations or STI Operations assets may not be recoverable.
