The filing reports fair value data as of June 30, 2026, and December 31, 2025, facilitating comparative analysis.

These disclosures provide transparency on monitoring the Haystack Oncology investment and contingent payment obligations linked to future performance or regulatory outcomes.

This partnership involves customer relationship intangible assets and represents strategic collaboration within the healthcare ecosystem, potentially expanding distribution channels and service offerings through integrated delivery networks.
Customer relationships recognized as intangible assets require ongoing impairment testing and valuation, especially if business performance declines.
