Ciena delivered a strong fiscal first quarter, beating on both earnings and revenue, but the market wasn’t impressed. The stock dropped sharply in premarket trading as investors zeroed in on the full-year guidance, which came in well below what analysts had expected.

Adjusted earnings per share came in at $1.35, clearing the analyst consensus of $1.17. Revenue reached $1.43 billion, a 33% jump from $1.07 billion in the same quarter last year. Wall Street had been looking for $1.4 billion.
CEO Gary Smith called it “unprecedented, broad-based demand” as customers look to capitalize on their AI investments.
The problem wasn’t the quarter. It was what came next.
Ciena guided full-year fiscal 2026 revenue to a range of $5.9 billion to $6.3 billion. The midpoint sits at $6.1 billion — well under the analyst consensus of $6.99 billion. That’s a gap that was always going to sting, especially for a stock that had run up 47% year-to-date heading into earnings.
The second quarter outlook was also measured. Ciena guided for Q2 revenue of $1.5 billion, plus or minus $50 million, with adjusted gross margin between 43.5% and 44.5%, and adjusted operating margin between 17.5% and 18.5%.
For the full year, the company raised its gross margin outlook to 43.5%–44.5%, up at the midpoint from the previous 42%–44% range. Adjusted operating margin for Q1 came in at 17.9%, up from 12.3% a year ago.
Ciena’s Optical Networking segment was the engine of the quarter, generating $1.02 billion in revenue — about 72% of total sales. That’s up from $728 million in the year-ago period.
Three customers each accounted for more than 10% of revenue, combining for 47.4% of total sales. That level of customer concentration is worth watching.
The company also bought back roughly 0.4 million of its own stock for $80.5 million during the quarter, as part of its $1 billion repurchase program.
CIEN fell 5.4% in premarket trading on Thursday. The stock had been one of the stronger performers in its space this year, carried by optimism around AI data center buildout and demand for networking infrastructure.
The Q2 revenue midpoint of $1.5 billion represents a modest step up from Q1’s $1.43 billion.
