As of Q2 2026, 34 SEC-registered investment managers reported holding BAND (BANDWIDTH INC) in their latest 13F filings, with a combined reported value of $668.89M across 13.27M shares. That is +3.4% by share count (+434.99K shares) versus the previous quarter, while reported value moved +312.8%. Ownership is concentrated: the five largest holders account for 54.5% of reported value and the top ten for 79.8%.

Compared with the prior quarter, 6 opened new positions, 17 added to existing stakes, 9 trimmed, 1 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

BAND is classified in the Technology sector.

All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
