Defused: “Hinge Health co-founder cuts holding by 100%” is a measurement artifact, and he has done the identical thing ten times this year

He converted 200,000 Class B shares to Class A and sold 200,000 Class A in four tranches the same day. The Class A line therefore closes at zero, which is what “−100%” measures. He still holds 2,720,306 Class B. The sales ran under a Rule 10b5-1 plan adopted 12 June 2026. The real break in his year is elsewhere, in the GRAT line — see the log.
