During the annual impairment testing conducted on October 1, 2025, 2024 and 2023, the Company bypassed the qualitative assessment and proceeded directly to the quantitative assessment. The Company performed its annual goodwill impairment assessment for all reporting units and determined that the estimated fair value of each reporting unit exceeded its carrying amount. Subsequent to the annual goodwill impairment assessment, it was determined the carrying amount of Goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in Goodwill impairment of $25.0 million. The impairment was primarily driven by a decline in projected cash flows due to lower customer demand, extending sales cycles and project funding uncertainty in the alternative energy industry.
During the year ended December 31, 2024, it was determined the carrying amount of Goodwill for the same reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in Goodwill impairment of $17.8 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections. Lower revenue projections primarily reflected the impact of delayed contract awards and the uncertainty that revenue will be realized for these contracts which are point-in-time revenue recognition contracts.
During the year ended December 31, 2023, it was determined the carrying amount of Goodwill for a different reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in Goodwill impairment of $5.1 million. The impairment was primarily driven by a decline in projected cash flows due to lower revenue projections and investments in support functions.
Impairment charges are presented in Goodwill impairment on the Consolidated Statements of Operations.

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.
