Context
This was a straightforward sale (disposition) rather than a purchase or option exercise. Sales by insiders can be routine (e.g., personal liquidity or tax reasons) and do not by themselves indicate a change in the insider’s view of the company. The amendment only corrects the price reported; there is no indication in this filing of derivative activity, tax withholding, or a 10b5-1 plan.
