TransUnion
TransUnion is a Public Limited Company registered in United States, and its current status with Illinois Secretary of State is active. Its registered address on file is Chicago, United States. 4 shareholders are on record for TransUnion, 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 Illinois Secretary of State and was last updated on 29 September 2026.

Shareholders of TransUnion
Four shareholders are currently on record for TransUnion, 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 13.3% — the largest recorded stake — followed by William Blair Investment Management, LLC at 3.3%; the remaining 2 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.

Those 85 subsidiaries span United States, Kenya, Rwanda, Botswana, South Africa, Chile, and 17 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. Eight of the 85 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
