Baron Asset Fund stated the following regarding Mettler-Toledo International Inc. (NYSE:MTD) in its fourth quarter 2025 investor letter:
“Strength in Health Care was driven by precision instruments provider Mettler-Toledo International Inc. (NYSE:MTD), while favorable stock selection in Financials came from specialty insurer Arch Capital Group Ltd. Mettler’s stock contributed to performance due to improving sentiment toward life sciences tools companies. This followed drug pricing agreements reached between large biopharmaceutical companies and the Trump Administration, which investors viewed as unlikely to have a material financial impact on pharmaceutical businesses. This development was also viewed as positive for life sciences tools providers that supply products and services to pharmaceutical companies for research and development. In addition, the Trump Administration appears to have scaled back some of its tariff threats against China. We believe Mettler is well positioned heading into 2026 as tariff headwinds fade, China stabilizes, and broader end-market demand accelerates. We continue to expect the company to compound earnings at a mid-teens or better rate over the long term, supported by underlying GDP growth, exposure to faster-growing emerging markets, market share gains, and price increases.”
