Over the past three months Ciena shares have climbed 42.6%, propelled by surging demand for AI-driven bandwidth solutions. The company reported a services and software backlog of $5 billion at the end of its latest quarter, representing a 25% increase year-over-year. Management raised its full-year 2026 revenue outlook by $150 million to a range of $4.35 billion to $4.45 billion, citing accelerated deployments with hyperscale cloud providers and telco customers seeking to upgrade optical networks for generative AI workloads.

Ciena completed its acquisition of Nubis for $270 million in cash, a strategic move to bolster its AI-ready data center interconnect portfolio. Nubis’s coherent optics technology supports line rates up to 800 Gbps per wavelength and reduces power consumption by 30% compared to previous solutions. Ciena expects to integrate Nubis’s engineering team by the end of Q2 2026, targeting $50 million in incremental revenue from new deployments by year-end. The deal is projected to be accretive to non-GAAP earnings per share in the first full year post-close, driven by cross-sell opportunities into Ciena’s existing 2000 customer base.
