6. Goodwill and Intangible Assets

During the three months ended March 31, 2026, the Company, through its Pinnacle Processes Inc. ("PPI") (formerly known as Effox-Flextor-Mader, Inc.) joint venture, completed the acquisition of Flexible Specialty Products ("FSP"), as discussed in Note 14.

During the three months ended June 30, 2026, the Company completed the acquisition of Thermon Group Holdings ("Thermon"), as discussed in Note 14.

In the second quarter of 2026, the Company shut down its Western Air Ducts business located in the United Kingdom. As a result, the Company recorded an impairment charge of $1.7 million related to finite life intangible assets. This was recorded to "'Other operating expense (income)" on the Condensed Consolidated Statements of Operations. In the first quarter of 2025, the Company completed the divestiture of its Global Pump Solutions business, and recognized $4.0 million related to the removal of the net book value of its intangible assets. This was recorded to "Gain on sale of Global Pump Solutions business" on the Condensed Consolidated Statements of Operations.

Amortization expense of finite life intangible assets was $7.8 million and $2.9 million for the three months ended June 30, 2026 and 2025, respectively, and $11.8 million and $6.0 million for the six months ended June 30, 2026 and 2025, respectively. Amortization over the next five years for finite life intangibles is expected to be $28.9 million for the remainder of 2026, $70.9 million in 2027, $68.2 million in 2028, $63.5 million in 2029, $62.7 million in 2030, and $705.2 million thereafter. The weighted average amortization periods for finite life intangible assets was 20.3 years as of June 30, 2026, inclusive of weighted average amortization periods for technology, customer lists, and tradenames and other of 19.4, 21.6, and 18.8 years, respectively.

Annually during the fourth quarter, or more often as circumstances require, the Company completes an impairment assessment of its goodwill and indefinite life intangible assets at the reporting unit level. As a part of its annual assessment, the Company first qualitatively assesses whether current events or changes in circumstances lead to a determination that it is more likely than not, defined as a likelihood of more than 50 percent, that the fair value of a reporting unit is less than its carrying amount. If there is a qualitative determination that the fair value of a particular reporting unit is more likely than not greater than its carrying value, the Company does not need to quantitatively test for impairment for that reporting unit. If this qualitative assessment indicates a more likely than not potential that the asset may be impaired, the estimated fair value is determined using a weighting of the income method and the market method. If the estimated fair value of a reporting unit is less than its carrying value, an impairment charge is recorded.

Additionally, property, plant and equipment, right-of-use assets, and finite life intangible assets are reviewed whenever events or changes in circumstances occur that indicate possible impairment. If events or changes in circumstances occur that indicate possible impairment, the impairment review is based on an undiscounted cash flows analysis at the lowest level at which cash flows of the long-lived assets are largely independent of other groups of assets and liabilities. When impairment is indicated, the estimated future cash flows are then discounted to determine the estimated fair value of the asset or asset group and an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

The Company did not identify any other triggering events that would require an interim impairment assessment, or record an additional impairment of goodwill, indefinite life intangible assets, finite life intangible assets, right-of-use assets, or property, plant and equipment during the three or six months ended June 30, 2026, other than as related to the Western Air Ducts business as discussed above.

The Company’s assumptions about future conditions important to its assessment of potential impairment are subject to uncertainty, and the Company will continue to monitor these conditions in future periods as new information becomes available and will update its analysis accordingly.
