The Company tests goodwill at the reporting unit level for impairment annually, during the fourth quarter of each fiscal year, or more frequently if events or circumstances indicate that the asset may be impaired. As a result of the segment change during the fourth fiscal quarter of 2025 discussed in “Note 19. Operating Segments and Geographic Information,'' management performed a goodwill impairment analysis on the reporting units prior to and after the change and did not identify an impairment.

No indications of impairment were identified under the qualitative assessment of goodwill impairment for fiscal years ending on June 28, 2025 and June 29, 2024.

In fiscal 2023, the Company performed a quantitative assessment of goodwill impairment for all reporting units. Based on our testing during the fourth quarter of fiscal 2023, the fair value of each of the Company’s reporting units was at least two times the carrying value, and therefore no impairment was identified.
