Context
These transactions reflect conversions of Class B shares and subsequent open-market sales (not a straightforward purchase). Conversions of founder/insider Class B stock to Class A and immediate sales are common mechanics for liquidity; the presence of a 10b5-1 plan for at least some sales indicates pre-planned execution rather than ad hoc trading. For complete ownership after the trades and any additional transactions, review Part 2 of this filing and the full Form 4 on the SEC EDGAR site.
