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.

How this page was built
This page was built from Ciena Corporation's own filings with the SEC, read one at a time, and 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.
