Ciena Corp reported record fiscal Q3 2026 revenue of $1.67 billion, up 37% year-over-year, with adjusted EPS of $2.11, up 215%, and adjusted operating margin of 22.5%, a record high. Backlog increased by $800 million to $8.5 billion, expected to exceed $10 billion by fiscal year-end. The company issued Q4 guidance of $1.75 billion revenue and fiscal 2027 preliminary outlook of at least 30% revenue growth to $8.3-$8.4 billion, with adjusted operating margin between 25% and 27%. CEO Gary Smith noted that demand is constrained by supply, with the 2027 guide described as a floor, and that the backlog is largely for existing data centers, making the company largely immune to new construction pacing for the next couple of years.
