[SCHEDULE 13D/A] Rocket Lab Corporation SEC Filing

Rhea-AI Filing Summary

Amendment No. 7 to a Schedule 13D reports ownership details for Rocket Lab Corporation (RKLB). The filing shows that Vinod Khosla, VK Services, and affiliated Khosla Ventures entities collectively hold significant common stock positions originally acquired via conversion of Legacy Rocket Lab preferred stock in the 2021 business combination.

VK Services and Vinod Khosla are reported as beneficial owners of 43,433,056 shares (9.0% of the class) and Khosla Ventures V, L.P. directly holds 11,323,617 shares (2.3%). Between July 23, 2025 and September 2, 2025, KV V distributed a total of 8,000,000 shares pro rata to its partners, leaving VK Services with 32,109,439 directly owned shares. The Reporting Persons state the shares are held solely for investment and have no present plans to change Rocket Lab's business or governance. The KV Funds have registration rights, including demand registration for offerings of at least $50 million and piggyback rights.

Insights

Financial Analyst

TL;DR: A disclosed 9.0% beneficial stake is material but presented as passive; registration rights enable future liquidity.

The filing documents concentrated ownership by VK Services and Vinod Khosla totaling 43,433,056 shares (9.0%) based on 482,413,301 shares outstanding. KV V's pro rata distributions of 8,000,000 shares between July and September 2025 shifted direct ownership, leaving VK Services with 32,109,439 shares directly. The Reporting Persons emphasize an investment-only purpose and no current plans to alter management or capital structure. The Registration Rights Agreement provides demand registration thresholds (minimum offering proceeds of $50 million) and piggyback rights, giving the holders a defined path to monetize positions while subject to customary limitations and issuer suspension periods.

Corporate Governance Expert

TL;DR: Significant affiliated ownership combined with voting/dispositive power warrants monitoring, though no change-in-control intentions are disclosed.

The schedule clarifies that voting and disposition powers are held indirectly across multiple affiliated entities and that Mr. Vinod Khosla and VK Services exercise shared voting/dispositive power over the aggregate 43,433,056 shares. While the Reporting Persons disclaim intent to pursue governance changes, the disclosure of coordinated ownership and the ability to engage with management means other shareholders and the board may view this as a material shareholder presence. All statements about plans are explicit and limited to the document; no speculative actions are asserted.

Item 3.	Source and Amount of Funds or Other Consideration
	From August 2013 through May 2020, the Reporting Persons acquired the following shares of preferred stock of Legacy Rocket Lab (as defined below): 6,271,165 shares of Series A Preferred Stock, 4,019,122 shares of Series B Preferred Stock, 2,177,599 shares of Series C Preferred Stock, 64,279 shares of Series D Preferred Stock, 158,571 shares of Series E Preferred Stock and 63,428 shares of Series E-1 Preferred Stock. The Reporting Persons acquired such shares for an aggregate purchase price of approximately $28.2 million. All such shares were acquired with working capital. The shares of Common Stock reported herein as beneficially owned by the Reporting Persons were acquired in connection with a business combination (the "Business Combination") contemplated by the Agreement and Plan of Merger dated March 1, 2021, and amended by Amendment No. 1 thereto, dated May 7, 2021, and Amendment No. 2 thereto, dated June 25, 2021 (the "Merger Agreement"), by and among Vector Acquisition Corporation ("Vector"), Rocket Lab USA, Inc. ("Legacy Rocket Lab"), and Prestige USA Merger Sub, Inc., a wholly-owned subsidiary of Legacy Rocket Lab. As a result of, and as the final step of, the Business Combination, on August 25, 2021 (the "Closing"), Legacy Rocket Lab merged with and into Vector, with Vector surviving the merger and being renamed "Rocket Lab USA, Inc." As a result of the Business Combination, the shares of preferred stock of Legacy Rocket Lab held by each of the Reporting Persons were converted into the right to receive a number of shares of Common Stock equal to an exchange ratio equal to 9.059659. As a result of such conversion, the Reporting Persons owned an aggregate of 115,004,795 shares of Common Stock immediately following the Business Combination. On May 23, 2025, Rocket Lab Corporation (the "Issuer", as previously defined) became the successor of Rocket Lab USA, Inc. pursuant to a merger. The merger resulted in Rocket Lab Corporation's becoming a parent holding company of Rocket Lab USA, Inc. but did not alter the proportionate interests of the security holders.
Item 4.	Purpose of Transaction
	The shares of Common Stock reported herein were acquired solely for investment purposes. None of the Reporting Persons have any present plans or proposals that relate to or would result in any change in the business, policies, management, structure or capitalization of the Issuer. The Reporting Persons reserve the right to acquire, or dispose of, additional securities of the Issuer in the ordinary course of their business, to the extent deemed advisable in light of their general investment and trading policies, market conditions or other factors. The Reporting Persons may engage in discussions from time to time with other stockholders of the Issuer regarding the acquisition by the Reporting Persons or others of shares of the Issuer's Common Stock held by such stockholders. The Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the actions described in subparagraphs (a) through (j) of this Item 4. However, the Reporting Persons may seek information from management and the Issuer's Board of Directors, and may engage in further discussions with management, the Issuer's Board of Directors, other stockholders of the Issuer and other relevant parties, concerning the business, operations, governance, management, strategy, capitalization and/or future plans of the Issuer, or in proposing one or more of the other actions described in subparagraphs (a) through (j) of this Item 4. In addition, the Reporting Persons may exercise their rights under the Second Amended and Restated Registration Rights Agreement, as defined below.
Item 5.	Interest in Securities of the Issuer
(a)	See responses to Items 11 and 13 on the attached cover pages. The aggregate percentage of shares of Common Stock reported beneficially owned by each person named herein is determined in accordance with SEC rules and is based upon 482,413,301 shares of Common Stock outstanding, which is the total number of shares of Common Stock outstanding as reported in the Prospectus Supplement filed by the Issuer with the Securities and Exchange Commission (the "SEC") on August 12, 2025. The applicable SEC rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities and include shares of Common Stock issuable upon the conversion or exercise of other securities that are immediately convertible or exercisable, or are convertible or exercisable within 60 days of the filing of this Schedule.
(b)	See responses to Items 7, 8, 9, and 10 on the attached cover pages.
(c)	Between July 23, 2025 and September 2, 2025, KV V conducted the following pro rata distributions for no consideration to its underlying limited partners and general partners (including KVA V), which include the distribution on September 2, 2025 that triggered the filing of this Amendment No. 7: (i) July 23, 2025 - 3,000,000 shares of Common Stock; (ii) August 1, 2025 - 1,000,000 shares of Common Stock; (iii) August 11, 2025 - 1,000,000 shares of Common Stock; (iv) August 18, 2025 - 1,000,000 shares of Common Stock; (v) August 25, 2025 - 1,000,000 shares of Common Stock; and (vi) September 2, 2025 - 1,000,000 shares of Common Stock. In the aggregate, 8,000,000 shares of Common Stock were distributed by KV V, resulting in 1,962,598 shares of such Common Stock ultimately being received by VK Services. Following all such distributions, as of the date of this Amendment No. 7, VK Services is the direct owner of 32,109,439 shares of Common Stock, and KVA V is the direct owner of no shares of Common Stock.
(d)	No other person is known to have the right to receive or the power to direct the receipt of dividends from, or any proceeds from the sale of, the shares of Common Stock beneficially owned by any of the Reporting Persons or the General Partner.
(e)	Not applicable.
Item 6.	Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer
	In connection with the Closing, on August 25, 2021, each of KV Seed B, KV Seed B (CF), and KV V (the "KV Funds") entered into a Second Amended and Restated Registration Rights Agreement (the "Registration Rights Agreement") with the Issuer (then known as Vector Acquisition Delaware Corporation), Vector Acquisition Partners, L.P., certain legacy investors of Vector party thereto and certain other investors of Legacy Rocket Lab party thereto, pursuant to which the KV Funds are entitled to registration rights with respect to their shares of Common Stock. The Registration Rights Agreement provides that the Issuer will, within 45 calendar days following the Closing, file with the SEC a shelf registration statement (the "Registration Statement") pursuant to Rule 415 of the Securities Act of 1933, as amended, and use commercially reasonable efforts to cause such Registration Statement to be declared effective as soon as practicable after the filing thereof, but no later than the earlier of (a) the 90th calendar day following the filing date if the SEC notifies the Issuer that it will "review" the Registration Statement and (b) the tenth business day after the date the Issuer is notified by the SEC that the Registration Statement will not be "reviewed" or will not be subject to further review. At any time when there is an effective shelf registration statement, the KV Funds may request to sell all or a portion of their registrable securities in an underwritten offering and the Issuer will facilitate such offering, provided that the registrable securities proposed to be sold in the offering have a total offering price of at least $50 million. Such demand registration rights are subject to certain issuer suspension periods, limitations on frequency and timing of demands and certain other conditions. In addition, the Registration Rights Agreement grants the KV Funds "piggyback" registration rights, subject to certain exceptions including that there cannot be an effective shelf registration statement available for the resale of holders' registrable securities at such time as piggyback rights are exercised. The Registration Rights Agreement also includes customary indemnification provisions. Further, the Issuer will bear all expenses incident to registering the securities, including any underwritten offerings, except such expenses shall not include any selling expenses such as underwriters' commissions and discounts, brokerage fees, underwriter marketing costs and legal fees incurred by the holders above a specified amount.
