“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.
