Shareholders
5
Five shareholders are currently on record for COSTAR GROUP 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 22.7% — the largest recorded stake — followed by Principal Financial Group, Inc. at 5.7%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 7 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.

The Senior Vice President Of Global Operations of COSTAR GROUP INC. currently on record is Lisa C. Ruggles; five officers are currently on record for COSTAR GROUP INC.
The register reports 13 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at COSTAR GROUP 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
COSTAR GROUP INC. has no recorded parent company — it sits at the top of its own group structure, with 27 subsidiaries recorded beneath it across 4 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 27 subsidiaries span United States, Australia, Canada, Colombia 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. Six of the 27 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
