Avantor, Inc. (AVTR) Stock Analysis

Avantor’s principal competitive advantages stem from its scale, breadth of proprietary offerings, and embedded customer relationships in the life sciences supply chain. The company serves over 300,000 labs in 180 countries, with more than 60% of revenue tied to biopharma and healthcare—sectors characterized by high regulatory barriers and sticky, recurring demand. Avantor’s proprietary materials and consumables account for over half of sales and are specified into 85% of the top 20 commercialized biologics, providing a degree of customer lock-in that is difficult for smaller or less specialized rivals to replicate.

Relative to peers such as Thermo Fisher Scientific and Danaher, Avantor’s business is less capital-intensive and more focused on consumables and services, which tend to be less cyclical and offer higher free cash flow conversion (105% in 2023–2024 vs. 75–93% for select peers). Its global supply chain and e-commerce platform enable efficient delivery and customer responsiveness, supporting high customer retention.

However, the market is fragmented and price competition is intense, particularly in laboratory consumables. Larger rivals like Thermo Fisher have broader portfolios and greater R&D resources, while regional players can undercut on price. Avantor’s recent cost transformation initiatives and focus on proprietary content are intended to defend margins and reinforce its position, but ongoing execution and innovation will be required to sustain its edge.
