The changes in the carrying amount of goodwill from December 31, 2025 to September 30, 2026, were as follows (in thousands):

Goodwill, September 30, 2026	$	77,226

In connection with the PTR acquisition, goodwill of $14.8 million was recorded resulting from the total consideration exceeding the fair value of the identifiable net assets acquired. The goodwill was assigned to the Artificial Lift and Downhole segment and is primarily attributable to expected revenue synergies and the assembled workforce. It is not expected to be deductible for income tax purposes.

Goodwill is not amortized and is tested for impairment at least annually or when events and circumstances indicate that fair value may be below its carrying value.

Intangible assets consisted of the following as of September 30, 2026 and December 31, 2025, respectively (in thousands):
