Ciena (CIEN) Q1 FY2026 Earnings Call — March 5, 2026

Source: Ciena Q1 FY2026 press release (Business Wire, Mar 5, 2026) + Motley Fool transcript (Mar 5, 2026).

Gary Smith (CEO): We delivered a very strong fiscal first quarter, driven by focused execution and unprecedented, broad-based demand as we enable customers to monetize their AI investments. We are investing and executing to deliver long-term value for our shareholders and to support the full range of high-speed connectivity needs for our customers.

Fiscal first quarter 2026 revenue was $1.43 billion, up 33% year over year and at the top end of our guidance — our highest-ever first-quarter revenue. Adjusted EPS was $1.35, more than double compared to the year-ago quarter. We remain in a supply-constrained environment with record backlog and strong visibility, and we are raising our fiscal 2026 revenue guidance to $5.9 billion to $6.3 billion, a 28% increase year over year at the midpoint.

Demand continues to be driven by AI networking: service providers and web-scale customers are expanding and upgrading their networks to support AI-driven traffic growth, and we are seeing strength across optical networking, routing and switching, and our WaveLogic portfolio.

[CFO commentary] Revenue was $1.427 billion, up 33.1% year over year, with products revenue of $1.180 billion and services revenue of $247 million. GAAP gross margin was 43.8% and non-GAAP gross margin was 44.7%. GAAP operating margin was 13.3% and non-GAAP operating margin was 17.9%. GAAP net income was $150.3 million, or $1.03 per diluted share, and adjusted net income was $196.9 million, or adjusted EPS of $1.35. Adjusted EBITDA was $287.3 million.

We generated operating cash flow of $227.6 million in the quarter. We ended the quarter with cash and investments of $1.4 billion.

For the fiscal second quarter, we expect revenue of approximately $1.5 billion, plus or minus $50 million. For fiscal 2026, we are raising our revenue guidance to $5.9 billion to $6.3 billion (a 28% increase at the midpoint), with adjusted gross margin between 43.5% and 44.5% and adjusted operating margin between 17.5% and 19.5%.

Q&A Highlights (condensed)

Q: Demand durability and AI-driven networking? A: Demand is unprecedented and broad-based — both web-scale and service providers are building out capacity for AI; record backlog and multi-quarter visibility; supply remains the constraint, not demand.
Q: Supply constraints and capacity? A: The company continues to execute capacity expansions to meet demand; component supply remains tight but improving.
Q: Customer concentration (cloud providers)? A: Demand breadth spans multiple hyperscalers and service providers; concentration is a factor to watch but the demand environment is broad.
Q: Optical vs routing growth? A: Growth is led by optical networking and the WaveLogic platform, with strong traction in data-center interconnect and AI-driven WAN builds.
