Ciena: Reasonable Valuation And Attractive Growth Outlook (Upgrade)

  • I am upgrading CIEN to a buy as 2Q25 results confirm a powerful new AI-driven growth cycle, with cloud orders doubling and service provider demand rebounding. CIEN's strategic wins in AI-specific applications and expanded presence in the value chain significantly increase its total addressable market and long-term growth runway. Service provider recovery is accelerating, with record MOFN activity indicating CIEN benefits from global AI infrastructure buildouts beyond just hyperscalers.
