Insights

Securities Analyst

TL;DR 4.6 % stake shows moderate institutional support; no control implications; impact limited.

William Blair’s amended 13G confirms ownership just under the 5 % threshold, ensuring passive status and avoiding Form 13D obligations. While the 3.65 million-share position reflects confidence in ZIP, it does not grant meaningful influence over governance or strategy. The disclosure mainly informs float composition and signals that a sizeable, fundamentally-oriented adviser remains invested. Market impact is typically modest unless other filings reveal accumulating or divesting trends.
