Context
This was an equity award (RSUs), not an open‑market purchase or sale. RSU grants are a common component of director compensation and do not by themselves indicate a buy/sell signal; the economic value to the insider depends on future vesting and the stock price at delivery. Per the filing, delivery of shares is subject to vesting and specific delivery timing tied to cessation of board service.
