Did CIEN Beat Earnings? Q2 2026 Results
Ciena Corporation delivered a standout fiscal second quarter, with revenue of $1.57 billion rising 39.5% year over year and adjusted EPS of $1.64 beating the $1.45 consensus estimate by 12.79%, as surging AI-driven demand for optical networking infrastructure powered results well ahead of expectations on both top and bottom lines. The central driver was hyperscaler spending, with cloud providers accounting for 46% of total revenue and growing 70% year over year; two customers alone combined for 34% of total sales, underscoring both the depth and concentration of that demand. Optical Networking led the revenue mix at $1.10 billion, while adjusted gross margin expanded 390 basis points to 44.9% and adjusted operating margin reached 19.5%. Management raised full-year fiscal 2026 revenue guidance to $6.30 billion, implying roughly 32% growth at the midpoint, and guided fiscal Q3 revenue to $1.63 billion with adjusted operating margin of 19% to 20%, projecting continued momentum as demand is described as outstripping supply and creating multi-year visibility for the company.
