[1] As a result of the organizational changes to the commercial structure within the Biopharma operating segment effective in the first quarter of 2025 (see Note 17A), our goodwill was reallocated among impacted reporting units. We completed the re-allocation during the first quarter of 2025 and concluded that none of our goodwill was impaired. All goodwill continues to be assigned within the Biopharma reportable segment.
[2] Additions in 2025 primarily represent our acquisition of Metsera and in 2024 primarily represent measurement period adjustments related to our acquisition of Seagen (see Note 2A).
