Shares owned after the transaction are not stated in the supplied filing excerpts.

Context

This was not an open-market purchase or sale by the insider: it reflects performance-based awards vesting and standard tax withholding (a common, non-speculative administration of compensation).
The withholding of shares to pay taxes is effectively a cashless settlement of the tax obligation and does not necessarily indicate a change in the insider’s market view.
For derivative entries: the filing shows conversions/exercises and related dispositions of derivative award units—these are settlement/reporting mechanics of the award, not open-market sales.
