Context

These dispositions appear to be automatic/contractual results of the merger rather than discretionary insider selling. The 15,000 derivative line reflects option/derivative conversion per the merger terms and may have had no cash value if not in‑the‑money relative to the $10.29 reference. Purchases generally carry more signal for bullish insider views; merger-driven dispositions are routine settlement mechanics.
