As a result of the filing of a Certificate of Merger with the Secretary of State of the State of Delaware, Merger Sub was merged with and into the Company and the Company became a wholly-owned subsidiary of ADTRAN Holdings (the “Merger”), effective at 7:00 am Eastern Time on July 8, 2022 (the “Effective Time”).
