AI Holders Summary · Q1 2026

APi Group's Q2 2026 tracked ownership is almost entirely Versant Capital Management: Versant holds about .1K of the .9K snapshot, roughly 97%, while MassMutual Private Wealth & Trust holds about 3% and CX Institutional is immaterial by value. The quarter's concrete signal is Versant's increase from 3,366 to 4,088 shares, with MassMutual also adding from 75 to 135, so APG's visible ownership grew but remained highly dependent on one account.
