During the three months ended June 30, 2026, the Company determined that the carrying amount of Goodwill for one reporting unit in the Engineering & Consulting segment exceeded fair value, resulting in a Goodwill impairment of $21.6 million recognized in Goodwill impairment on the Condensed Consolidated Statement of Operations during the three and six months ended June 30, 2026. The impairment was primarily driven by a decline in new contracts during the three months ended June 30, 2026, due to lower customer demand for sustainability services, which resulted in declining revenue, margins and cash flow projections.

During the three months ended June 30, 2026, the Company determined that a triggering event had occurred for long-lived assets related to one asset group in the Engineering & Consulting segment. The triggering event occurred as a result of a decline in new contracts during the three months ended June 30, 2026, due to lower customer demand for sustainability services, which resulted in declining revenue, margins and cash flow projections. The Company determined that the carrying amount of long-lived assets for the asset group exceeded fair value, resulting in a long-lived asset impairment of $19.5 million recognized in Long-lived asset impairment on the Condensed Consolidated Statement of Operations during the three and six months ended June 30, 2026. The asset group's fair value was estimated using an income approach. The

income approach utilizes discounted future cash flows and key assumptions including the estimated life the asset will contribute to cash flows, revenue growth rates and EBITDA margins, attrition rate of customers, as well as the estimated discount rate that reflects the level of risk associated with receiving future cash flows.
