> Ciena says AI demand for optical networking gear is outrunning supply, with backlog headed past $10 billion even as its shares slid 10% after earnings.

Ciena is selling optical networking gear faster than it can build it, and the company is thrilled to tell you so. On Thursday's earnings call, CEO Gary Smith said, "we are currently projecting to exit fiscal 2026 with over $10 billion in backlog," according to Fierce Network. Light Reading frames the same milestone as year-end.

The quarter was a stunner: revenue of $1.67 billion, up 37% from $1.22 billion, and EBITDA up 220% to $349 million from $109.2 million. About half of Ciena's business now comes directly from hyperscalers. Chief Strategy Officer David Rothenstein says orders grew 50% from 2024 to 2025 and another 50% from 2025 to 2026, while supply is not coming online at that rate. The bottlenecks are pump lasers, ceramic packaging and memory.

Ciena has signed supply deals with key partners through 2029, and CFO Mark Graff expects high single-digit price increases, depending on customer and product line. Ciena expects supply to catch up with demand in the second half of 2028, with backlog normalization taking longer.

Wall Street was not applauding. Shares fell 10% the day after, to $317, nearly half off June's high of $627. B. Riley's David Kang points to shifting sentiment in AI networking trades and a 6% sequential drop in routing and switching revenue tied to the Meta program, which management called lumpiness.

My take: a company with more orders than it can ship, expecting price increases, with a CEO who has seen a telecom crash before. Even Rothenstein concedes a giant backlog can turn into "a scarlet letter" rather than a badge of honor. I still adore the problem.
