Context

• Sales executed under a 10b5‑1 plan are pre-arranged and commonly used by insiders to sell shares without active timing decisions; they are viewed as routine but should be noted.
• For retail investors, purchases by insiders generally carry more direct signaling value than routine sales; this filing documents a planned liquidity event by the CEO rather than an acquisition.
