Context

• The primary line is an option exercise (acquisition). The companion $0 disposition is not a cash sale; Form 4s sometimes show a simultaneous conversion, net settlement, or other administrative disposition when derivatives are exercised or converted. This filing does not detail post-exercise share retention or exact settlement mechanics — refer to the company’s proxy and Form 4 footnotes for fuller disclosure.
