Schedule 13G/A (Amendment No. 1) by BlackRock, Inc., a Delaware parent holding company, discloses its aggregated beneficial ownership through subsidiaries like BlackRock Advisors, LLC and others listed in Exhibit A. As of January 31, 2024, BlackRock holds 23,964,290 shares of RKLB Class A Common Stock, representing 4.9% of the class, with sole voting power over 23,629,305 shares and sole dispositive power over all. Item 5 confirms BlackRock has ceased to be a >5% beneficial owner, triggering this passive investor filing under Rule 13d-1(b). Certification affirms holdings are in ordinary course of business, without intent to influence control. This update follows prior 13G filings when ownership exceeded 5%, providing transparency on institutional positioning in Rocket Lab, a space launch provider.

Neutral signal for RKLB investors; BlackRock's passive reduction below 5% likely reflects portfolio rebalancing rather than negative view on fundamentals. Removes a major institutional holder from >5% watchlist, potentially easing overhang concerns. Monitor future 13F filings for further sales and Rocket Lab's launch cadence for growth validation.
