ADAPTIVE BIOTECHNOLOGIES CORPORATION
ADAPTIVE BIOTECHNOLOGIES CORPORATION is a registered legal entity registered in United States under 602952386, and its current status with Washington Secretary of State is active. The company was incorporated on 8 September 2009 and lists its registered address as SEATTLE, United States. 5 shareholders are on record for ADAPTIVE BIOTECHNOLOGIES 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 Washington Secretary of State and was last updated on 22 September 2026.

Shareholders

Shareholders of ADAPTIVE BIOTECHNOLOGIES CORPORATION
Five shareholders are currently on record for ADAPTIVE BIOTECHNOLOGIES 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 11.1% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 3.7%; 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.
