Item 8.01 Other Events.

Rocket Lab Corporation (the “Company”) anticipates holding its 2026 annual meeting of stockholders (the “2026 Annual Meeting”) on May 20, 2026. Because the date of the 2026 Annual Meeting will change by more than 30 calendar days from the anniversary of the date of the Company’s 2025 annual meeting of stockholders, the Company has set a deadline for the receipt of stockholder proposals submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (“Rule 14a-8”) for inclusion in the Company’s proxy materials relating to the 2026 Annual Meeting. In order for a proposal under Rule 14a-8 to be timely, it must be received by the Company’s Secretary at the principal executive offices of the Company by March 22, 2026, which the Company has determined to be a reasonable time before the Company’s proxy materials are due to be printed and sent. Such proposals must also comply with the Company’s Amended and Restated Bylaws (the “Bylaws”) and the rules of the Securities and Exchange Commission regarding the inclusion of stockholder proposals in proxy materials, and any such proposal may be omitted if not in compliance with applicable requirements.

The address of the Company’s principal executive offices is 3881 McGowen Street, Long Beach, California 90808.

Stockholders wishing to nominate a director or propose matters to be considered at the 2026 Annual Meeting in the manner contemplated by the Bylaws must submit timely notice thereof to the Company in order for such matters to be considered at the 2026 Annual Meeting. Because the date of the 2026 Annual Meeting will be earlier than 30 days from the first anniversary of the Company’s 2025 annual meeting of the stockholders, in accordance with Section 2(a)(2) of the Bylaws, to be timely, such notice must be received by the Secretary at the address above by March 22, 2026. Such proposals must also comply with all other requirements set forth in the Bylaws and other applicable laws.
