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.” (the “Issuer”, as previously defined).

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.

In addition, if the closing price of the Common Stock is equal to or greater than $20.00 for a period of at least 20 trading days out of 30 consecutive trading days during the period commencing on the 90th day following the Closing and ending on the 180th day following the Closing, the Reporting Persons will be entitled to receive an aggregate of 9,293,441 additional shares of the Issuer.

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.

Other than as described above in Item 3 of this Schedule 13D, 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.

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 449,204,556 shares of Common Stock outstanding, which is the total number of shares of Common Stock outstanding as reported in Prospectus Supplement No. 4 to the Prospectus dated October 7, 2021, which forms a part of Registration Statements on Form S-1 (Registration Nos. 333-259797 and 333-257440), filed with the Securities and Exchange Commission (the “SEC”) on November 16, 2021.
