Over 56% of Simpson Manufacturing Co Inc's (SSD) total reported 13F capital ($40.15 million out of $70.69 million) was concentrated in just two institutional asset managers—Riverbridge Partners LLC and River Road Asset Management, LLC—both of which executed massive, simultaneous capital extractions in Q2 2026. Riverbridge Partners pulled $11.85 million in net outflows to land at $26.04 million (124,379 shares), while River Road Asset Management extracted $10.80 million in net flow to land at $14.12 million (67,424 shares).
