Avantor, Inc.

For information regarding factors that could affect the Company's results of operations, financial condition and liquidity, see the risk factors discussed in Part I, Item 1A “Risk Factors” in our Annual Report and the following risk factor, which supplements and should be read in conjunction with the risk factors discussed in Part I, Item 1A “Risk Factors” in our Annual Report.

Our VWR Distribution reporting unit is at risk of goodwill impairment, which could result in a material non‑cash charge.

Our consolidated balance sheet includes goodwill, intangible assets and other long-lived assets that must be periodically evaluated for potential impairment. We assess the realizability of the reported goodwill, intangible assets and other long-lived assets annually, as well as whenever events or changes in circumstances indicate that the assets may be impaired. During the first quarter of 2026, a sustained decline in our share price and market capitalization constituted a triggering event that required an interim goodwill impairment assessment. Although no impairment was recorded, the VWR Distribution reporting unit is considered at risk of impairment because the estimated fair value exceeded the carrying value by a limited margin. The valuation is sensitive to adverse changes in operating performance, forecasted cash flows, discount rates and market conditions. If these factors deteriorate, we could be required to record a material non‑cash goodwill impairment charge in a future reporting period (see note 7 to the unaudited condensed consolidated financial statements included in this quarterly report).
