DESCRIPTION OF THE BUSINESS	DESCRIPTION OF THE BUSINESS Rocket Lab Corporation (“Rocket Lab” and, together with its consolidated subsidiaries, the “Company,” “we,” “us” or “our”) is an end-to-end space company with an established track record of mission success headquartered in Long Beach, California and is the parent company for several wholly owned operating subsidiaries located in the United States, New Zealand, Germany, Canada and Australia. We deliver reliable launch services, spacecraft design services, spacecraft components, spacecraft manufacturing and other spacecraft and on-orbit management solutions that make it faster, easier and more affordable to access space. We operate one of the only private orbital launch ranges in the world, located in Mahia, New Zealand, enabling a unique degree of operational flexibility and control of customer launch manifests and mission assurance. While our business has historically been centered on the manufacture of small-class launch vehicles and related sale of launch services, we are currently innovating in the areas of medium-class launch vehicle and launch services, space systems design and manufacturing, on-orbit management solutions, and space data applications.
