BBH Select Series – Mid Cap Fund stated the following regarding Bruker Corporation (NASDAQ:BRKR) in its third quarter 2025 investor letter:
“The Fund’s largest detractors to performance in the quarter were Shift4 Payments Inc. (Shift4), Globant S.A. (Globant), and Bruker Corporation (NASDAQ:BRKR). We exited both Globant and Bruker during the quarter following sustained underperformance and to opportunistically harvest tax losses. These two companies have been our most impacted by tariffs and life science and academic funding cuts, and any re-entry would be predicated on a stabilization in performance.
Bruker declined -18.4% during the quarter through the date of our exit. Bruker is a leading provider of high-per formance scientific instruments, analytical and diagnostic solutions, and related services. BBH Mid Cap has long admired Bruker’s innovative track record that has allowed the company to consistently grow its revenue alongside operational excellence that has facilitated strong margin expansion and earnings growth. Bruker is diversified across a wide variety of end markets including academic, government, biopharma, industrial, and semiconductor. Bruker is also geographically diversified with about a third of its revenues each in North America, Europe, and Asia. However, this diversification has provided no safe harbor from academic and government life science funding cuts and prolonged tariff uncertainty. These include restrictions on federal research funding to colleges and universi ties; efforts to cut the National Institutes of Health (NIH) and National Science Foundation (NSF) budgets and limit the pace of grant disbursements; tariffs on China, the EU, and Switzerland; and policy to re-shape the biopharma industry via sector-specific pharmaceutical tariffs and most-favored-nation drug pricing. While the impact was ini tially contained to direct funding cuts among academic customers in the US (approximately 10% of revenues), more recently we have seen a sharp slowdown in activity across Europe and China, and in industrial and biopharma end markets. Given continued policy uncertainty, both at the country and healthcare sector level, we have chosen to step aside at this time while we await a stabilization of the policy landscape and to redeploy proceeds to readily available opportunities.”
