During the three month period ended June 28, 2026, the Company and its HPC segment realized a triggering event in relation to the implied enterprise value of the HPC business associated with the noncontrolling interest recognized as part of the HPC Transaction, impacting market related inputs and assumptions used in assessing the value for indefinite lived intangible assets held by the HPC business unit. As a result, we recognized an impairment charge of $104.0 million for the three and nine month periods ended June 28, 2026 on related indefinite lived intangible assets.
