Latest analysis: Ciena FY2026 Q3 Earnings: $1.67B Revenue (+37%) and Two Cloud Customers Buying 41.7% of It

Key Figures

Amounts in MUSD (millions of US dollars), exactly as the ledger records them.

What's Inside

Fiscal years end on the Saturday nearest October 31 (52/53-week years; FY2024 was 53 weeks, ending November 2, 2024); SEC CIK 0000936395. FY2021–FY2025 come from Form 10-K filings and FY2026Q3 (quarter ended August 1, 2026) from the Form 10-Q and the Q3 earnings release (8-K Exhibit 99.1). Amounts carry three decimals so every figure equals the filing's thousands exactly.

Quick Start

uvx --from beancount bean-check main.bean
uvx --from beanquery bean-query main.bean \
  "SELECT year, sum(position) WHERE account ~ '^Income:Revenue' GROUP BY year ORDER BY year"

Zero output from bean-check means the ledger is internally consistent: every
income statement sums to zero and every balance-sheet snapshot reconciles to
the filed totals. The query prints revenue by calendar year; income is a
credit, so it shows as a negative number. Open main.bean in Fava
or import it into beancount.io to explore it visually.

Methodology

• Balance sheet — pad / balance directives assert each period-end
  figure against the filing named in that period file's source banner.
• Income statement — one zero-sum transaction per period: Income
  negative (credit), Expenses positive (debit), with the arithmetic check in
  a comment directly above it.
• Unit — MUSD; 1,671.129 MUSD means 1,671.129 million US dollars.
• Additional accounts — Assets:Current:Inventory, opened beyond the
  standard chart (see each account's open line in main.bean).

Analysis

• Ciena FY2026 Q3 Earnings: $1.67B Revenue (+37%) and Two Cloud Customers Buying 41.7% of It — FY2026Q3
