• Quantity: 1,173 RSUs reported as acquired; reported price: $0.00 (derivative award).
• Shares owned after transaction: not specified in this filing.
• Footnotes: F1 — RSUs granted under the 2020 Stock Plan for Non-Employee Directors and represent a right to one share or cash equivalent. F2 — RSUs are fully vested at grant and will be settled in stock or cash on the first business day 90 days after a separation from service.

Context
RSUs are a form of compensation/award, not an open-market purchase or sale. Because these RSUs are fully vested at grant but settlement is deferred until separation (or will be settled per plan terms), this filing reflects a compensation award to a director rather than an active buy/sell decision. Such awards are commonplace for non-employee directors and do not, by themselves, indicate insider buying or selling sentiment.
