Goodwill and intangible assets
Goodwill
During fiscal year 2026, the additions to the Company’s goodwill are driven by its acquisitions of Bentek Corporation (“Bentek”), OnSight Technology Inc. (“OnSight”), Origami Solar, Inc. (“Origami”) and Fracsun Inc. (“Fracsun”), as further described below in Note 14. The additions to goodwill during fiscal year 2025 are driven by the Company’s acquisitions of Ojjo, Inc. (“Ojjo”) and the solar foundations business held by Solar Pile International (“SPI”).
The following table summarizes the activity in the Company’s goodwill during the fiscal year ended March 31, 2026 and 2025 (in thousands):

The Company evaluates goodwill for impairment at the reporting unit level annually, and in certain circumstances, such as when there is a change in reporting units or whenever there are indications that goodwill might be impaired. The Company performed its annual goodwill impairment assessment on January 1 of each fiscal year, and assessed qualitative factors to determine whether it is more likely or not that the fair value of its reporting units is less than its carrying amount. The qualitative assessment required management to make various judgmental assumptions including but not limited to macroeconomic conditions, industry and market considerations, cost factors, financial performances, and change in stock price. Management assessed each factor and evaluated whether the evidence, in aggregate, would indicate that it is more likely than not that the Company’s reporting unit is less than its carrying amount. As a result of the qualitative assessment of its goodwill, the Company determined that no impairment existed as of the dates of the impairment tests because the fair value of its reporting unit exceeded its carrying value.
Other intangible assets
Nextpower amortizes identifiable intangible assets consisting of developed technology, customer relationships, and trade names because these assets have finite lives. Nextpower’s intangible assets are amortized on a straight-line basis over the estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized over their estimated useful lives. No residual value is estimated for any intangible assets.
Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. An impairment loss is recognized when the carrying amount of an intangible asset exceeds its fair value. The fair value of Nextpower’s intangible assets is determined based on management’s estimates of cash flows and recoverability. Nextpower reviewed the carrying value of its intangible assets as of March 31, 2026 and 2025, and concluded that such amounts continued to be recoverable.

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.
