Did the net cash from operating activities of Ciena for the quarter ended October 31, 2026 come to at or above 9.0% of its revenue?
Divide the net cash from operating activities by the revenue that Ciena reports for the quarter ended October 31, 2026 in its 10-Q or 10-K filing on SEC EDGAR. The answer is yes if the ratio is at or above 9.0%; no if it is below 9.0%.
If the source is late or silent: If Ciena has not filed by December 17, 2026, or a filing restates a period the rule reads, the test is inconclusive, and the Result says what was read and what was missing.
