News Summary:

Ciena Corporation has established concrete targets for the surge in AI-related networking demand, entering fiscal 2027 with management anticipating at least 30% revenue growth. This outlook, driven by AI-driven bandwidth demand across cloud and data-center networks, follows the company's fiscal third-quarter results, which recorded $1.67 billion in revenue—a 37% year-over-year increase—and demonstrated faster growth, expanded cloud exposure, and improved profitability as customers added optical capacity. On September 10, Ciena Spark launched a Data Centre Connectivity Service across Auckland, capitalizing on an expected NZ$10 billion investment into New Zealand's data center growth over the next decade, where 56 data centers are currently operational and another 20 are planned. Earlier the same day, new guidance refocused attention on Ciena's growth trajectory, with AI networking demand central to its valuation story, although analysts noted that a premium valuation creates a tougher earnings-growth test.
