View the composition of the DAX 40 and the weighting of all companies in the DAX 40 here. The stock price becomes sensitive to trends in biotech investments, regulations surrounding drug development and macroeconomic factors such as interest rates and industrial growth. As a technology-oriented company, Sartorius often reacts strongly to sentiment in life sciences and biotech such as IPOs or innovation projects.
Investment analysis & outlook
Sartorius shares have lost about 18% over the past 12 months, partly due to lower sales growth, pressure on margins and a cooling investment appetite in the biotech sector. Nevertheless, there are signs of recovery. In the first half, sales rose 6% to €1.77 billion, while underlying net profit rose almost 14% to €169 million. Sartorius maintained its outlook for 2025, with stable sales growth, especially within the Bioprocess Solutions division.
The sharp spike in 2021, visible in the chart below, came from Sartorius profiting from the corona pandemic. However, this led to a prolonged correction as pandemic-related demand declined. Since then, the stock price has remained under pressure, partly due to uncertainty in the biotech sector. The stock's valuation remains high, with a price-to-earnings ratio above the industry average, making it susceptible to disappointing figures or external shocks.
Still, the growing demand for biologics and single-use technologies offers structural opportunities. Investors who believe in the long-term growth potential of the sector may see the current price level as an attractive entry point. The chart below shows that Sartorius has recently shown signs of bottoming out, which could be a potential turning point for some investors.
News & updates
In July 2025, Sartorius announced additional investments in its global production capacity, particularly in the area of single-use technologies essential for biologics production. In doing so, the company emphasized the importance of scalability and digitization as spearheads for future growth.
In addition, it became clear that demand for repeatable bioprocess products is recovering faster than expected, leading management to confirm earnings expectations for 2025. Sartorius also took steps in the area of sustainability by setting further reduction targets for CO₂ emissions within its supply chain. The company thus continues to profile itself as an innovative and reliable player in a market that increasingly focuses on efficiency and climate responsibility.
