Key Details

  • Transaction type/code: Grant / Award (A).
  • Quantity: 4,353 RSUs; reported acquisition price $0.00.
  • Shares owned after transaction: not disclosed in the filing.
  • Footnote: RSUs vest on June 1, 2027, subject to Bowman's continuous service through the earlier of that vesting date or the registrant's next annual shareholder meeting. (See F1.)

Context
RSU grants are a common form of equity compensation and do not involve an immediate cash outlay or market sale — the economic value will be realized only if and when the units vest and convert to shares (and then potentially sold). Such awards are routine and should be interpreted as compensation, not a direct trading signal.
