Willdan Group, Inc.

**Signal Note: Driehaus Capital initiates WLDN position** Willdan Group is an engineering/consulting firm focused on energy efficiency and infrastructure—not a biotech company. This position likely reflects conviction in Willdan's growth in EV charging infrastructure and grid modernization consulting, sectors benefiting from IRA funding acceleration, though this represents a notable diversification away from Driehaus's traditional biotech focus and warrants monitoring for strategy shifts.
