QUANTERIX CORPORATION
QUANTERIX CORPORATION is a registered legal entity registered in United States under 0450006915, and its current status with New Jersey Division of Revenue & Enterprise Services is active. The company was incorporated on 28 July 2015 and lists its registered address as LEXINGTON, United States. 2 shareholders are on record for QUANTERIX 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 New Jersey Division of Revenue & Enterprise Services and was last updated on 25 September 2026.

Shareholders of QUANTERIX CORPORATION
Two shareholders are currently on record for QUANTERIX 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 9% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 1.4%. 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.

Data availability
Those 5 subsidiaries span United States, Sweden, Netherlands, Hong Kong 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.
