Form 144 is a notice of proposed sale of restricted securities under Rule 144 by affiliates like officers. Here, Rocket Lab Corporation officer Arjun Kampani plans to sell 10,554 common shares (NASDAQ: RKLB) through Morgan Stanley, with aggregate market value $449,600 based on 534M shares outstanding. Shares were acquired 11/22/2025 via RSU vesting from the issuer, with sale targeted for ~11/26/2025. The transaction relies on a 10b5-1 plan established 12/12/2024, which pre-schedules trades to avoid insider trading issues. Kampani certifies no undisclosed material adverse information. Past 3 months' sales by Kampani: 28,615 shares on 11/24/2025 ($1,163,248), 9,416 on 09/17/2025 ($449,189), and 31,185 on 09/16/2025 ($1,527,058). This reflects typical post-vesting liquidity for executives in Rocket Lab's space launch business, where RSUs are key compensation amid growth investments.

Routine 10b5-1 sale of vested RSUs provides executive liquidity without signaling distress, as pre-planned and with no adverse info certification. Negligible impact on share float (0.01% of outstanding). Strategic: Common in high-growth space sector; monitor aggregate insider sales for sentiment on Neutron rocket progress or bookings. Near-term: Minimal price pressure expected.
