Rocket Lab Becomes a Publicly Traded Company Through $777 Million Merger with Vector Acquisition Corporation

The Special Purpose Acquisition Companies and Technology teams advised Rocket Lab USA (Nasdaq: RKLB) in the completion of its merger with Vector Acquisition Corporation (Nasdaq: VACQ) to take Rocket Lab public. Vector’s shareholders approved the merger at an annual general meeting of Vector’s shareholders on August 20, 2021. The combined company will retain the Rocket Lab USA, Inc. name and commenced trading on the Nasdaq Capital Market on August 25, 2021, with its common stock and warrants trading under the new ticker symbols, “RKLB” and “RKLBW”, respectively.
