Ameresco, Inc.

**Signal Note: Driehaus Capital Initiates $14.8M Position in Ameresco (AMRC)** Notably, this represents a growth-focused investor entering a renewable energy/efficiency company rather than a biotech play—Ameresco is a clean energy infrastructure provider, not a pharmaceutical asset. This signals conviction in the broader energy transition market, though the position size ($14.8M) is modest relative to Driehaus's typical biotech deployment, suggesting either a portfolio diversification move or conviction in near-term operational catalysts (potential government contract wins under clean energy mandates).
