Form 144 is a notice required under Rule 144 for insiders proposing sales of restricted or control securities. Rocket Lab USA Inc. officer Arjun Kampani reports acquiring 13,787 and 38,685 common shares (total 52,472) via restricted stock vesting on 11/22/2024 as compensation. To cover resulting tax liabilities, he plans to sell 7,505 shares through Morgan Stanley on or about 11/25/2024 (aggregate value $181,212.73 based on market price ~$24.14/share) and lists 21,057 shares (value $508,433.90, ~$24.15/share) with approximate sale date 08/23/2024. No securities sold by him in the past 3 months. Kampani certifies no knowledge of undisclosed material adverse information about Rocket Lab. This is standard 'sell-to-cover' practice for executives, minimizing net proceeds while complying with tax withholding; the 08/23 date may reflect a prior tranche or planned execution, but no recent sales noted.

Routine sell-to-cover by officer represents ~0.006% of 504M outstanding shares, negligible dilution or signaling risk. Confirms no known adverse info, aligning with standard compensation practices amid Rocket Lab's growth trajectory. Investors should monitor for selling patterns or context via future Forms 4/144, but this isolated event has minimal near-term impact.
