ADTRAN HOLDINGS, INC.
ADTRAN HOLDINGS, INC. is a registered legal entity registered in United States under 6141966, and its current status with Delaware Division of Corporations is active. The company was incorporated on 8 October 2021 and lists its registered address as United States. 5 shareholders are on record for ADTRAN HOLDINGS, INC., 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 Delaware Division of Corporations and was last updated on 3 October 2026.

Shareholders
5
Five shareholders are currently on record for ADTRAN HOLDINGS, INC., 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 17.7% — the largest recorded stake — followed by DnB Asset Management AS at 6.3%; 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.

The Vice President Of Finance & Administration Planning of ADTRAN HOLDINGS, INC. currently on record is Ulrich Dopfer; five officers are currently on record for ADTRAN HOLDINGS, INC., filed with Delaware Division of Corporations.
The register reports 10 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at ADTRAN HOLDINGS, INC. 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
ADTRAN HOLDINGS, INC. has no recorded parent company — it sits at the top of its own group structure, with 5 subsidiaries recorded beneath it across 5 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 5 subsidiaries span United States, Tunisia, Israel, Germany, South Africa 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. Two of the 5 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
