Screeners show the co-founder and executive chairman at −100%, holding zero after selling 200,000 shares on 12 October for about $20.63m. Read the form and the −100% applies to one line only. He converted 200,000 Class B into Class A (code C) and sold exactly those 200,000 in four price-banded tranches at $101.53, $102.53, $103.48 and $104.34 weighted averages. Class A direct afterwards: zero, because he never held Class A to begin with.

What he still holds: 1,644,004 Class B directly, 383,592 in a family trust, and 692,710 in a GRAT — 2,720,306 in total. The 200,000 sold is about 6.9% of his pre-trade Class B. The sales were made under a Rule 10b5-1 plan adopted 12 June 2026, four months before execution. I went looking for the anomaly the screener implies and there isn't one: this is a plan running on schedule, and the only unusual thing on the page is the measurement.
