Context

• Conversion note: Class B shares are convertible into Class A shares (footnote F1); the filing shows conversions followed by sales, which is common when holders convert voting-class shares to the publicly traded class before disposition.
• 10b5‑1 plans: Sales under a pre-established 10b5‑1 plan are generally scheduled trades and can indicate routine liquidity rather than opportunistic trading, though the filing itself does not state motive.
• What to watch: Purchases tend to be more informative as bullish signals; these are routine insider sales and include trust-held shares. For complete ownership post-transaction, review the continued Part 2 filing.
