March 1, 2021 – Rocket Lab USA and Vector Acquisition Corporation, a special purpose acquisition company backed by leading technology investor Vector Capital, announced today that they have entered into a definitive merger agreement that will result in Rocket Lab becoming a publicly traded company. The transaction is estimated to be completed in Q2 2021 and, at that time, Vector will change its name to Rocket Lab USA, Inc. and the combined company will trade under the Nasdaq ticker symbol RKLB. Rocket Lab is transforming the way we use and access space by delivering end-to-end solutions across the launch and space systems markets. Since the Company’s first orbital launch in 2018, its innovative Electron launch vehicle has become the second most frequently launched U.S. rocket annually. To date, Rocket Lab has delivered 97 satellites to orbit for more than 20 public and private-sector organizations and technology-leading constellation operators. Rocket Lab’s customer base is evenly split across government and commercial organizations including the National Aeronautics and Space Administration (NASA), the National Reconnaissance Office (NRO), and the Defense Advanced Research Projects Agency (DARPA), as well as commercial satellite leaders. As the first company to deliver regular and reliable dedicated launch services for small satellites, Rocket Lab has also played a leading role in catalyzing the growth of the commercial small satellite industry. The satellites launched by Rocket Lab enable operations in national security, Earth observation, space debris mitigation, weather and climate monitoring, communications and scientific research.
