The company posted adjusted earnings per share of $1.64, representing a significant increase from $0.42 in the year-ago period and handily beating the Street’s $1.46 estimate. Total revenue reached $1.57 billion, marking a robust 40% year-over-year increase and topping the consensus forecast of $1.51 billion.

What explains the stock’s decline? The answer lies in forward guidance — and investor expectations that had soared to extraordinary heights following a 749% rally over the trailing 12-month period.

Management elevated its fiscal year revenue outlook to $6.3 billion, with a variance of plus or minus $100 million. This represents an upgrade from the previous forecast range of $5.9 billion to $6.3 billion. While analysts had projected $6.18 billion, the revised guidance technically exceeds expectations — though only marginally.

Looking ahead to Q3, the company projected revenue of approximately $1.625 billion, give or take $50 million.

Sector-Wide Weakness Hammers Optical Equipment Names

The earnings release coincided with unfavorable conditions across the broader industry. Optical networking companies experienced widespread selling pressure Thursday: Lumentum retreated 4.2%, Coherent slid 5.6%, Marvell declined 6.5%, and Corning fell 4.5%.

This marked a dramatic about-face from Tuesday’s session, when the group surged following Nvidia CEO Jensen Huang’s identification of Marvell as a potential future “trillion-dollar company.” The episode illustrates how rapidly momentum can reverse.

Ciena’s quarterly revenue composition revealed optical networking generated $1.1 billion, representing 70% of consolidated revenue. The routing and switching segment contributed $174 million, while platform software and services added $93.9 million.

Profitability Metrics Remain Solid as AI Infrastructure Fuels Expansion

GAAP gross margin registered at 44.0%, while adjusted gross margin reached 44.9%. Adjusted operating income totaled $307.1 million, translating to an adjusted operating margin of 19.5%. Adjusted EBITDA for the period came in at $341.8 million.

Executives attributed the revenue acceleration to artificial intelligence-related networking infrastructure demand, coupled with ongoing operational efficiency improvements that bolstered margin performance.

Two major customers each accounted for over 10% of quarterly sales, combining to represent 34% of total revenue during the reporting period.

Ciena bought back approximately 200,000 shares for $83.1 million throughout the quarter as part of its authorized $1 billion share repurchase initiative.

GAAP diluted earnings per share totaled $1.49, with net income of $218.2 million recorded for the quarter.

Days sales outstanding measured 71 days, while inventory turnover registered at 3.6 times for the period.
