Ciena reported a 23.6% year-over-year increase in revenue for its fiscal second quarter ended May 3, 2025, reaching $1.13 billion, up from $910.8 million in the same period last year. The growth was driven by strong global demand for high-speed optical and network infrastructure, particularly from AI and cloud deployments.
GAAP net income for the quarter was $9 million, or $0.06 per share, reversing a loss of $16.8 million last year. On an adjusted basis, net income reached $60.7 million, or $0.42 per share, compared to $39.4 million and $0.27 per share in Q2 FY2024. Adjusted EBITDA rose 36% year-over-year to $116.7 million. Operating margin improved to 8.2% on a non-GAAP basis, while adjusted gross margin declined 2.5 percentage points to 41.0%.
Ciena’s Networking Platforms segment remained the primary revenue driver, contributing $866.3 million or nearly 77% of total revenue. Optical Networking revenue surged to $773.6 million, offsetting a dip in Routing and Switching. The company also reported gains in Global Services and Blue Planet software, with the latter nearly doubling to $28 million. Ciena repurchased 1.2 million shares for $84.3 million during the quarter and reported $1.35 billion in cash and investments.
