“To be included in a prominent index like the Russell 2000® as a newly listed company complements our record revenue this past quarter and demonstrates our continued momentum,” said Ouster CEO Angus Pacala. “We expect our presence in the index to drive increased awareness of Ouster, our innovative digital approach to lidar, and our ability to enable automation across the supply chain as we further diversify our shareholder base.”

Membership in the Russell 2000® Index, which remains in place for one year, is based on membership in the broad-market Russell 3000® Index.
