The business, in plain English
Ciena Corp booked $4.8B of revenue in FY2025 in the Technology sector and kept 42.0% of it as gross profit — a solid-margin business by that measure. After every other cost, 2.6% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $902.4M (FY2008) to $4.8B (FY2025) — about 10.3% a year compounded over 17 years.
It earned 4.9% on invested capital in FY2025, with a median of 7.3% across 14 filed years. The Returns on Capital filter above scores it 36/100.
The balance sheet carried $1.5B of total debt in FY2025. Balance-Sheet Safety scores it 25/100.
The share count rose 53.2% between FY2009 and FY2025 — existing owners have been diluted over the record. Capital Discipline scores it 42/100.
Put together: Pricing Power is the strongest of the four filters (72/100) and Balance-Sheet Safety the weakest (25/100), which is how CIEN lands at 46/100 — a Shallow moat.
This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Gaps in a line mean that item isn’t in CIEN’s filings for that year — the series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.
