REPLIGEN CORPORATION
REPLIGEN CORPORATION is a registered legal entity registered in United States under 5799034, and its current status with California Secretary of State — bizfile Online is active. The company was incorporated on 29 June 2023 and lists its registered address as WALTHAM, United States. 3 shareholders are on record for REPLIGEN 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 California Secretary of State — bizfile Online and was last updated on 22 September 2026.

Shareholders of REPLIGEN CORPORATION
Three shareholders are currently on record for REPLIGEN 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 13.7% — the largest recorded stake — followed by MFS Series Trust IV-MFS Mid Cap Growth Fund at 2.3%; the remaining 1 shareholder shown holds 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 15 subsidiaries span United States, South Korea, France, Singapore, Sweden, United Kingdom, and 1 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. Three of the 15 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
