PeriodQ3 FY2026
Published
Ciena Corporation reported $1.67 billion in revenue for Q3 FY2026, the quarter ended August 1, 2026, up 37.0% from a year earlier, as cloud providers building out AI networks bought more of its optical systems and pluggable modules. Net income was $266.42 million, or $1.83 per diluted share, against $50.31 million, or $0.35, in the same quarter a year earlier. Most of the gain came from operations: operating income was $301.18 million, against $73.53 million, as gross margin widened, and lower interest expense after Ciena refinanced its term loan added to it.

| Company | Ciena Corporation |
| Business type | industrial |
| Schema template | standard technology hardware: product and services revenue, cost of goods sold, gross profit, operating expenses by line, income from operations, net income, EPS and weighted shares; cash, investments, receivables, inventories, debt and equity; operating cash flow, capital expenditures, free cash flow, share repurchases and the financing lines; revenue, segment gross profit and segment profit for each of the four operating segments |
| Schema rationale | Ciena sells optical networking and routing hardware, software and services to cloud providers, service providers and other network operators. Its statement of operations splits revenue and cost of goods sold between products and services, and it measures its four operating segments (Networking Platforms; Platform Software and Services; Blue Planet Automation Software and Services; Global Services) on segment profit, so the record carries those lines as printed. Ciena pays no cash dividend, so none is reported. |
| Reporting currency | USD |
| Converted to USD | no |
| Units | actual dollars (not thousands); share counts in actual shares; per-share amounts in dollars per share. Expense, outflow and loss lines carry the sign the statement prints them with: interest expense, losses on debt extinguishment and cash outflows are negative; cost and operating expense lines and the provision for income taxes are positive amounts that are subtracted. |
| Fiscal calendar note | Ciena's fiscal year is a 52- or 53-week year ending on the Saturday nearest the last day of October. Fiscal 2025 ended November 1, 2025 and fiscal 2023 ended October 28, 2023, each 52 weeks; fiscal 2024 ended November 2, 2024 and had 53 weeks, the extra week falling in its fourth quarter. Fiscal 2026 is a 52-week year; its third quarter ended August 1, 2026. |

- Derivation. Fiscal 2025 (from the fiscal 2025 Form 10-K, accession 0001628280-25-056698) plus the nine months ended August 1, 2026 less the nine months ended August 2, 2025 (both from the third-quarter fiscal 2026 Form 10-Q, accession 0001628280-26-060361), line by line. Ciena does not publish a trailing-twelve-month statement; these figures are computed, not printed. Per-share amounts and weighted-average share counts are not additive across periods and are not reported for this view.

|---|---|
| ADR ratio | n/a |

Notes
- Sources: the fiscal 2025 annual figures and the November 2, 2024 balance sheet are from Ciena's fiscal 2025 Form 10-K (accession 0001628280-25-056698). The third-quarter figures for fiscal 2026 and fiscal 2025, the August 1, 2026 balance sheet and both nine-month periods are from the third-quarter fiscal 2026 Form 10-Q (accession 0001628280-26-060361). The same third-quarter statements of operations, balance sheet and nine-month cash flows are reproduced unchanged in the earnings release furnished on September 3, 2026 (accession 0001628280-26-060245).
- Every figure is taken from the statement face, which Ciena prints in thousands of dollars (per-share amounts in dollars; weighted-average share counts in thousands), and is stored here in actual dollars and actual shares.
- Operating income is the line Ciena captions 'Income from operations'. Revenue and cost of goods sold are each split between products and services exactly as the statement of operations prints them.
- Total debt is the current portion of long-term debt plus long-term debt, net, as carried on the balance sheet (net of unamortized debt issuance costs). It excludes operating and finance lease liabilities.
- Capital expenditures are the cash flow line 'Payments for equipment, furniture, fixtures and intellectual property' (fiscal 2025 Form 10-K) and 'Payments for equipment, furniture and fixtures' (fiscal 2026 Form 10-Q). Free cash flow is operating cash flow less that line; Ciena does not report a free cash flow figure in these statements.
- Shares outstanding are the common shares Ciena reports issued and outstanding at each balance sheet date (141,897,511 at August 1, 2026; 141,016,300 at November 1, 2025; 142,656,116 at November 2, 2024).
- Segment figures are Ciena's four operating segments as reported in the segment note of each filing (Note 24 of the fiscal 2025 Form 10-K; Note 19 of the third-quarter fiscal 2026 Form 10-Q). Segment profit excludes selling and marketing, general and administrative, restructuring, share-based compensation, intangible amortization, acquisition costs and all non-operating items, so the segments do not sum to consolidated operating or net income; total segment gross profit likewise differs from consolidated gross profit by the unallocated cost of goods sold Ciena reports.
- Fiscal 2024 contained 53 weeks, one more than fiscal 2023, fiscal 2025 and fiscal 2026, with the extra week in its fourth quarter. Annual comparisons that include fiscal 2024 are therefore not on an identical-length basis.
- Third-quarter fiscal 2026 financing: on June 11, 2026 Ciena issued $2.875 billion of 0.00% Convertible Senior Notes due 2031, used the proceeds to repay the full $1.14 billion outstanding under its Refinanced 2030 Term Loan, paid $988.4 million for convertible note hedges and received $873.4 million from the sale of warrants. At August 1, 2026 the 2031 Notes were carried at $2,832.2 million net of $42.8 million of unamortized issuance costs. This is why long-term debt rose from $1,524.2 million at November 1, 2025 to $3,229.8 million at August 1, 2026. Net cash provided by financing activities of $987.9 million in the nine months contributed to the rise in cash and cash equivalents from $1,092.0 million to $2,445.7 million.
- The third-quarter fiscal 2026 loss on extinguishment and modification of debt of $7.1 million relates to the repayment of the term loan; interest expense in that quarter is reduced by a $7.8 million gain on terminating the related interest rate swaps, which Ciena reports within interest expense.
- The trailing-twelve-month view is computed as fiscal 2025 plus the nine months ended August 1, 2026 less the nine months ended August 2, 2025. A cash flow line that a statement does not print for a period is treated as zero for that period, so business acquisitions and the convertible note hedge, warrant and convertible note lines are computed for that view on the same basis as every other line.
- Ciena has not paid cash dividends and states that it does not anticipate paying them, so no dividend line is reported. Ciena had no stock splits in the periods covered, and no currency translation or ADR adjustment applies.
Uncertainties
- No three-month cash flow figures are reported for either third quarter. Ciena's Form 10-Q and its earnings release print the cash flow statement for the nine months only, and the six-month statement needed to isolate the quarter is in the second-quarter filing, which is not among the filings this page is built from.
- No balance sheet is reported as of August 2, 2025 or for fiscal 2023, because neither filing presents one.
- The quarter start dates (May 3, 2026 and May 4, 2025) are the day after each fiscal second quarter ended under Ciena's 52/53-week calendar (second quarter of fiscal 2026 ended May 2, 2026); the Form 10-Q states the quarter-end dates but not the start dates.

How this page was built
This page was built from three of Ciena Corporation's own filings with the SEC, read one at a time. Nothing on it is taken from a pre-tagged dataset, a data vendor or another website. The figures are on the company's own fiscal calendar and in actual dollars, as the filings report them. Where the filings do not support a figure, the record says so instead of reporting a zero; this period names three such gaps.
A single company files thousands of pages with the SEC in a year, and no two companies file them the same way, so the reading and the assembly here are done by AI rather than by rules that break on the differences. Every pass is then audited back against the filings it came from before the page is published, and anything the filings do not support is left out and named rather than filled in. AI can still make mistakes. That is why the accession numbers are printed: the filing is the authority, and this page is a route to it.
