Broyhill Asset Management Christopher R. Pavese | “Avantor was a close second. When we initiated the position, we underwrote a classic recovery setup: orders bottom, gradually recover, and earnings inflect. While this cycle has played out longer than we initially expected, with uncertainty magnified by unpredictable government policy, the industry upturn has become increasingly difficult to ignore. The issue for Avantor has been that a cyclical downturn morphed into competitive and operational challenges, with company-specific execution masking the industry upturn. Consequently, we cut the position in half after the company announced management changes and second-quarter results that again fell short of our expectations, and reinvested the proceeds into Thermo Fisher, the primary beneficiary of Avantor's challenges. We continue to maintain our reduced position in the company as we view AVTR as a rare strategic asset with multiple self-help levers, with the option of a strategic sale should those levers fail to impress recently engaged activists. BSD Analysis: Avantor is positioning 2026 as a pivotal transition year, launching a comprehensive restructuring program known as Project Revival to restore organic growth and margin health. The company is doubling down on its flagship VWR brand and digital e-commerce capabilities to enhance the customer interface and capture emerging demand in bioprocessing and lab solutions. While end-market uncertainty in government and education remains a headwind, the underlying shift toward specialized bioscience production provides a durable long-term tailwind. Management's focus on optimizing its business segments and reducing processing costs is aimed at creating a more agile and profitable enterprise by the end of the year. For investors, Avantor represents a tactical turnaround play within the essential life sciences supply chain, with significant potential for valuation re-rating as the revival plan hits its operational milestones.” | BULL | Q4 2025 Feb 17, 2026 | View Pitch |
Longleaf Partners Global Fund Ross Glotzbach | “We added a partial position of Avantor to the portfolio in the second half of the year after (and then while) the company had some self-inflicted ups and downs. It is probable that the worst is in the past for Avantor after a leadership change and guidance reset, but we felt it best to exit and book a loss before year end. BSD Analysis: Avantor is the infrastructure backbone of labs and biopharma manufacturing, supplying mission-critical consumables that customers can't easily substitute. Volume slowed as biotech funding tightened, but demand didn't disappear—it deferred. The company's scale and logistics network create switching costs that matter when operations restart. Debt and margin compression hurt sentiment, but cash generation remains real. Investors confuse near-term destocking with structural decline. As funding and production normalize, operating leverage returns. Avantor is a picks-and-shovels play that the market currently treats like a broken tool.” | BEAR | Q4 2025 Jan 1, 2026 | View Pitch |
