AI Holders Summary · Q2 2026

Impinj's Q2 2026 tracked ownership is almost entirely Versant Capital Management: Versant holds about .5K of the .0K snapshot, roughly 97%, while MassMutual Private Wealth & Trust owns the remaining 3%. The quarter's important detail is that both holders reduced share count—Versant from 2,104 to 2,091 and MassMutual from 85 to 73—so PI's reported value rose while its visible institutional exposure got slightly smaller.
