Context
Bealmear exercised options (a cost to acquire shares at the stated strike) and immediately sold a portion (16,430 shares) — a routine “exercise and sell” pattern often used to cover option exercise costs or diversify. The sale was made under a 10b5‑1 plan, which specifies prearranged parameters for selling shares and is commonly used to avoid timing questions about insider sales. The $0.00 “disposed” derivative entries reflect conversion/reporting mechanics for the exercised options rather than additional cash-sale proceeds.
