- Ciena delivered Q2 adjusted earnings per share of $1.64, surpassing the Street’s $1.46 estimate, while revenue climbed 40% to $1.57 billion
- CIEN stock declined 5.7% in premarket action despite outperforming on both earnings and revenue metrics
- The company boosted its full-year revenue outlook to $6.3 billion, matching the upper end of its previous forecast
- Broader weakness hit optical networking equities, with Coherent, Marvell, and Corning all posting losses
- The downturn followed Tuesday’s rally sparked by Nvidia CEO Jensen Huang naming Marvell a future “trillion-dollar company”
Ciena (CIEN) stock slumped 5.7% during premarket hours Thursday following the release of fiscal second-quarter results that exceeded analyst projections across key financial metrics.
The company posted adjusted earnings per share of $1.64, a substantial increase from $0.42 in the year-ago period and significantly higher than the analyst consensus of $1.46. Revenue reached $1.57 billion, marking a 40% year-over-year surge and beating the Street’s $1.51 billion forecast.
What explains the stock’s decline? The answer lies in forward guidance — combined with stratospheric expectations following a 749% rally in the trailing 12 months.
Ciena lifted its full-year revenue projection to $6.3 billion, with a potential variance of $100 million in either direction. This represents an increase from the previous guidance range of $5.9 billion to $6.3 billion. While analysts had forecast $6.18 billion, the updated outlook merely matches the prior high-end estimate rather than exceeding it.
Looking ahead to Q3, the company provided revenue guidance of $1.625 billion, plus or minus $50 million.
Optical Networking Stocks Already Under Pressure
The earnings release arrived during a difficult trading session for the entire sector. Optical networking companies faced widespread selling pressure Thursday: Lumentum shed 4.2%, Coherent lost 5.6%, Marvell declined 6.5%, and Corning dropped 4.5%.
This represents a dramatic turnaround from Tuesday’s session, when these stocks surged following Nvidia CEO Jensen Huang’s characterization of Marvell as a prospective “trillion-dollar company.” Momentum that builds rapidly can evaporate just as swiftly.
Breaking down Ciena’s quarterly revenue composition, optical networking generated $1.1 billion, representing 70% of the total. Routing and switching operations added $174 million, while platform software and services produced $93.9 million.
Margins Hold Up as AI Demand Drives Growth
The company reported a GAAP gross margin of 44.0%, while adjusted gross margin reached 44.9%. Adjusted operating income totaled $307.1 million, yielding an adjusted operating margin of 19.5%. Adjusted EBITDA for the period came to $341.8 million.
Executives credited AI-driven networking infrastructure demand as the primary catalyst for revenue expansion, alongside continued operational efficiency improvements supporting margin performance.
Two major clients each comprised over 10% of quarterly sales, combining for 34% of the quarter’s total revenue.
Ciena bought back approximately 200,000 shares for $83.1 million throughout the quarter as part of its existing $1 billion share repurchase authorization.
GAAP diluted earnings per share stood at $1.49, with quarterly net income of $218.2 million.
Days sales outstanding registered at 71, while inventory turns measured 3.6 for the reporting period.
