Context
Restricted stock units are a form of compensation that convert to shares upon vesting; the reported sale was a routine sell‑to‑cover to meet tax obligations and should not be read as an independent investment decision by the director. This filing reports a compensation award plus the related tax withholding sale rather than a discretionary purchase or sale for investment purposes.
