Spok Inc.
Spok Inc. is a registered legal entity registered in United States under F1523705, and its current status with Virginia State Corporation Commission is active. Its registered address on file is United States. 5 shareholders are on record for Spok 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 Virginia State Corporation Commission and was last updated on 4 October 2026.

Shareholders
5
Five shareholders are currently on record for Spok 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 Blackrock Inc., holding 14.2% — the largest recorded stake — followed by Renaissance Technologies, LLC at 13.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
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.
| Shareholder | Type | Holding | Source Document |
|---|---|---|---|
| Blackrock Inc. | 14.2% | Virginia State Corporation Commission | |
| Renaissance Technologies, LLC | 13.8% | Virginia State Corporation Commission | |
| Vanguard Group Inc | 10.8% | Virginia State Corporation Commission | |

Officers
5
The Chief Operating Officer of Spok Inc. currently on record is MICHAEL W. WALLACE; five officers are currently on record for Spok Inc., filed with Virginia State Corporation Commission.
The register reports 12 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Spok 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
Spok Inc. has no recorded parent company — it sits at the top of its own group structure, with 5 subsidiaries recorded beneath it across 1 jurisdiction. 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 jurisdiction, 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.
