Background of the Merger

On March 1, 2021, Vector and Rocket Lab entered into a definitive merger agreement that will result in Rocket Lab becoming a publicly traded company.  Rocket Lab is a world-leading space company that is transforming the way we use and access space by delivering end-to-end solutions across the launch and space systems markets. The company develops satellite and spacecraft solutions for a range of commercial and government missions, from low-Earth orbit constellations to high-complexity deep space and interplanetary missions. 

Once the merger is complete, Vector will change its name to Rocket Lab USA, Inc. and the combined company will trade under the Nasdaq ticker symbol RKLB and RKLBW.  Proceeds from the transaction will be used to fund development of the reusable Neutron launch vehicle, a launch vehicle with an 8-ton payload lift capacity tailored for mega constellations, deep space missions, and human spaceflight. The proceeds will also be used for organic and inorganic growth in the space systems market and will support expansion into space applications, enabling Rocket Lab to deliver data and services from space.

Vector’s Board of Directors has unanimously recommended that its shareholders approve the transaction. If you were a shareholder as of the close of business on June 30, 2021, you are eligible to vote and will receive a proxy card with voting instructions.

Vector’s Annual Meeting of Shareholders (“Annual Meeting”) will be held on August 20, 2021 to approve the transaction.
