Context

• This was an award of performance share units (not a market purchase or sale). PSUs convert to shares only if performance and vesting conditions are met; no cash changed hands at grant. Such awards indicate compensation tied to company performance and continued service, but do not by themselves signal an insider buying or selling stock.
