What insider transaction did BWX Technologies (BWXT) report for Nicole Piasecki?

BWX Technologies reported that director Nicole Weyerhaeuser Piasecki received a grant of 762 restricted stock units. These RSUs are equity compensation and each unit represents a contingent right to receive one share of BWXT common stock in the future, subject to delivery terms.

How many restricted stock units did the BWXT director receive in this Form 4 filing?

The BWXT director received 762 restricted stock units in this transaction. Each RSU corresponds to one share of BWX Technologies common stock, providing equity-based compensation rather than a cash payment. The grant increased her directly held RSU balance to 762 units after the award.

Did the BWXT restricted stock units for Nicole Piasecki vest immediately?

Yes, the restricted stock units granted to Nicole Weyerhaeuser Piasecki vested immediately. Although the RSUs vested at once, she chose to defer receipt of the underlying BWXT shares, so the actual share delivery will occur under a scheduled installment plan after board service ends.

When will Nicole Piasecki receive the BWXT shares underlying her restricted stock units?

She will receive the BWXT shares in five annual installments beginning one year after her service on the Board of Directors terminates. This timing follows her deferral election, which postpones actual share delivery despite the RSUs vesting immediately on the grant date.

Is this BWXT Form 4 transaction an open-market stock purchase or sale?

No, this transaction is not an open-market purchase or sale. It is a grant of restricted stock units as part of BWX Technologies’ 2020 Omnibus Incentive Plan, representing equity compensation awarded to director Nicole Weyerhaeuser Piasecki rather than a market trade.

What plan governs the restricted stock unit grant reported by BWX Technologies (BWXT)?

The restricted stock unit grant to Nicole Weyerhaeuser Piasecki was made under BWX Technologies’ 2020 Omnibus Incentive Plan. This plan provides for equity-based awards such as RSUs, giving directors and other participants compensation tied directly to BWXT common stock performance over time.
