Form 144 is a notice of proposed sale of restricted securities by an affiliate under Rule 144. Here, Rocket Lab Corp officer Adam C. Spice intends to sell 62,744 shares of common stock through Morgan Stanley on or around March 2, 2026, with an aggregate market value of $4,366,347.18 based on the filing date, against 567,445,449 shares outstanding. The shares stem from compensation via vesting of 114,845 restricted stock units acquired from the issuer on March 1, 2026. The filing explicitly notes the sale includes amounts to satisfy tax withholding on the vested equity award settlement. Spice previously sold 1,365,665 shares on January 5, 2026, for gross proceeds of $103,112,350.76. Spice represents no knowledge of undisclosed material adverse information about Rocket Lab.

This is a routine sell-to-cover transaction for tax obligations on vesting equity, common among executives and representing a negligible fraction of shares outstanding or Spice's prior activity. It poses no near-term threat to shareholders, as Rocket Lab's operations remain unaffected, and the required representation confirms no hidden adverse developments. Investors should monitor subsequent Form 144s or 4s from Spice or other insiders for any escalation in selling volume that might signal confidence shifts, but this filing aligns with standard compensation practices in the high-growth space sector.
