Perimeter Solutions, Inc.

# Signal Note: Driehaus Capital Initiates PRM Position **What happened:** Growth-focused Driehaus established a $23.9M stake in Perimeter Solutions, a specialty chemicals company focused on forestry and agricultural solutions, not a traditional biotech play. **Why it matters:** This signals conviction in PRM's operational turnaround or M&A potential, though the position lacks typical biotech catalysts (clinical data, regulatory milestones); investors should verify whether this reflects confidence in management execution or anticipates strategic consolidation in the specialty chemicals space. **Key risk:** Driehaus's biotech expertise may not translate to materials/chemicals sector analysis.
