BlackRock, Inc., a Delaware parent holding company, filed this Amendment No. 1 to Schedule 13G on July 18, 2025, for the event date of June 30, 2025, regarding Rocket Lab Corp (RKLB, CUSIP 773121108). It reports aggregate beneficial ownership of 22,072,112 common shares, equating to 4.8% of the class, with sole voting power over 21,178,814 shares and sole dispositive power over all 22,072,112 shares. No shared powers. Item 5 confirms ownership of 5% or less, indicating a drop below the prior >5% threshold that triggered initial 13G filing. BlackRock certifies passive holding in ordinary course of business, not for control or influence, across its reporting business units. Various clients may direct dividends/sales, but none exceed 5%. This routine amendment reflects institutional position trimming, common for asset managers like BlackRock managing Rocket Lab amid space industry volatility.

BlackRock's stake reduction to 4.8% below the 5% threshold is a minor, passive adjustment typical for large asset managers rebalancing portfolios, unlikely to materially impact Rocket Lab's stock near-term. It ends BlackRock's 13D/G reporting but signals no activism or distress. Investors should monitor overall institutional ownership trends and Rocket Lab's cap table stability amid growth in launches and Neutron rocket development.
