CIENA CORPORATION
CIENA CORPORATION is a Public Limited Company registered in United States under 112229F1, and its current status with Maryland Department of Assessments and Taxation is active. Its registered address on file is Hanover, United States. 5 shareholders are on record for CIENA CORPORATION, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Maryland Department of Assessments and Taxation and was last updated on 3 October 2026.

Shareholders
5
Five shareholders are currently on record for CIENA CORPORATION, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 13% — the largest recorded stake — followed by JPMORGAN CHASE & CO at 11.6%; the remaining 3 shareholders shown hold smaller stakes.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Director of CIENA CORPORATION currently on record is JAMES MOYLAN; five officers are currently on record for CIENA CORPORATION, filed with Maryland Department of Assessments and Taxation.
The register reports 42 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at CIENA CORPORATION sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
CIENA CORPORATION has no recorded parent company — it sits at the top of its own group structure, with 13 subsidiaries recorded beneath it across 8 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 13 subsidiaries span United States, Spain, Thailand, India, Mexico, Canada, and 2 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 13 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
