• Employees: Nubis employees will join Ciena, with retention arrangements in place. Ciena's R&D team will be strengthened.
• Customers: Expected to benefit from enhanced, scalable, high-performance connectivity solutions for AI workloads inside data centers.
• Competitors: Ciena aims to expand its competitive advantage in the data center interconnect market.

Next Steps

• Complete the acquisition of Nubis Communications, expected during Ciena's fiscal fourth quarter 2025.
• Integrate Nubis's technologies and over 50 engineers into Ciena's operations.
• Advance development of differentiated solutions for AI workloads.
• Enter into certain employee retention arrangements in connection with the transaction.
