# Ciena: Business Model & Revenue Engine



## Direct Answer

Ciena reports revenue across 4 business segments in its fiscal 2025 Form 10-K. Networking Platforms is the largest, with $3.7 billion of revenue (77% of the total), followed by Global Services at $614 million (13%).

## How Does Ciena Make Money?

Networking Platforms supplies 77% of revenue, so Ciena's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Blue Planet Automation Software and Services grew fastest (+48.9%) and Platform Software and Services slowest (+1.6%), so the revenue mix tilts toward Blue Planet Automation Software and Services while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Networking Platforms | $3.7 billion | $3.0 billion | 77.1% | 20.9% |
| Global Services | $614 million | $537 million | 12.9% | 14.2% |
| Platform Software and Services | $364 million | $358 million | 7.6% | 1.6% |
| Blue Planet Automation Software and Services | $116 million | $78 million | 2.4% | 48.9% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of Ciena's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value Ciena reported in the segment note and revenue disclosures of its Form 10-K filed December 12, 2025 (accession 0001628280-25-056698), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
