Amprius Technologies, Inc.

**Signal Note: Driehaus Capital Initiates $18.9M Amprius Position** Driehaus's new position in Amprius (AMPX-WT) signals confidence in the company's silicon nanowire anode technology for next-generation lithium-ion batteries, targeting EV and energy storage markets where density and cycle life drive competitive advantage. The ~$19M entry by a growth-focused manager with significant biotech/deeptech exposure suggests conviction in near-term commercialization catalysts, likely tied to customer adoption announcements or production scale-up milestones. Note: Amprius is a battery technology play rather than biotech; this may reflect Driehaus's broader clean energy/advanced materials exposure rather than traditional pharma thesis.
