Context

This is a compensation award tied to company performance, not a market purchase or sale. Such awards are common for executives and reflect plan payouts tied to multi‑year operational and relative total‑shareholder‑return goals. Because the units are derivative and vest over time, they do not necessarily indicate immediate buying or selling of company stock.
