Context

• These were sales, not purchases—sales are commonly routine (e.g., planned disposals or tax/liquidity events) and do not necessarily indicate a change in the insider’s view of the company.
• The derivative conversions reflected are simply the corporate mechanism converting Series B common stock into Series A common stock (1:1 conversion per certificate of incorporation), enabling the open‑market sale.
