Trading volume showed solid growth, and market capitalization stood near $50 billion to $54 billion. The company designs and sells optical networking systems, interconnect products, and automation software that enable high-volume data transmission across networks and AI data centers, positioning it to benefit from expanding global data and AI demand.
Record Third-Quarter Results Show Strong Demand
Ciena’s fiscal 2026 third-quarter results underscored its growth trajectory, with revenue of $1.67 billion representing a 37% increase from $1.22 billion in the year-ago quarter. Adjusted earnings per share reached a record $2.11, up 215% from $0.67 a year earlier, while GAAP diluted EPS rose to $1.83 from roughly $0.35 previously. Adjusted gross margin improved to approximately 46.4%, and adjusted operating margin hit a record 22.5%, more than doubling the prior-year figure and exceeding guidance.
Cloud provider customers accounted for 53% of total revenue during the quarter, up 82% year-over-year. Two major customers alone represented about 41.7% of total sales, with most growth driven by networking platforms and optical systems. Backlog also surged by $800 million quarter-over-quarter to $8.5 billion, and the company expects to finish fiscal 2026 with more than $10 billion in backlog, with most orders scheduled for delivery in 2027 or later.
Strong Q3 results—including robust revenue, record adjusted EPS, and a swelling backlog—lifted the stock and bolstered analyst sentiment.
Guidance Raised for 2026 and Longer-Term Targets Set
Ciena raised full-year fiscal 2026 revenue guidance to $6.42 billion, implying roughly 35% growth year-over-year. For Q4, the company expects approximately $1.75 billion in revenue, with gross margin around 45% and operating margin near 20%. Looking further ahead, Ciena outlined fiscal 2029 long-term financial targets at its Investor Forum on September 16, 2026, aiming for approximately $14 billion in revenue—representing roughly 30% annual growth from 2026 levels. The company also targets adjusted gross margin near 50%, adjusted operating margin between 32% and 35%, and free cash flow margin around 20%.
AI Demand, Subsea Wins, and Product Momentum
A primary driver of Ciena’s rapid expansion is the rapid growth of AI data centers, which require high-speed connections capable of handling massive data loads. Ciena is capitalizing on this demand through offerings such as coherent optical pluggables, RLS Hyper Rail, and other data-center networking solutions.
Ciena has also secured several major subsea cable projects, including a selection by the Africa Coast to Europe (ACE) consortium to upgrade a roughly 17,000-kilometer route connecting Western Europe, West Africa, and South Africa. The upgrade is expected to deliver more than 30 terabits per second of capacity using Ciena’s technology. Additionally, the company is seeing strong demand in metro networks; for instance, its work with CtrlS Datacenters in India involves connecting multiple facilities with capacity of up to 100 Tb/s, highlighting broader demand for high-capacity optical networking.
