Note 7 - Goodwill

 

All identifiable goodwill as of April 30, 2025 and January 31, 2025, is attributable to the purchase of the remaining 50% interest in Perma-Pipe Canada, Ltd., which occurred in 2016.

 

The Company performs an impairment assessment of goodwill annually as of January 31, or more frequently if triggering events occur that could indicate that more likely than not that the fair value of the reporting unit did not exceed its carrying value, resulting in an impairment.
