APELLIS PHARMACEUTICALS, INC.
APELLIS PHARMACEUTICALS, INC. is a registered legal entity registered in United States under 604465210, and its current status with Washington Secretary of State is active. The company was incorporated on 21 May 2019 and lists its registered address as WALTHAM, United States. 3 shareholders are on record for APELLIS PHARMACEUTICALS, INC., 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 3 October 2026.

Shareholders
3
Three shareholders are currently on record for APELLIS PHARMACEUTICALS, 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 11.2% — the largest recorded stake — followed by UBS Group AG at 4.4%; 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.

Group Structure
APELLIS PHARMACEUTICALS, INC. sits 1 level below its ultimate parent, Biogen Inc., registered in United States. 7 subsidiaries are recorded beneath it, across 3 jurisdictions. The full chain up to Biogen Inc. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by APELLIS PHARMACEUTICALS, INC.'s own shareholder record. 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 7 subsidiaries span United States, Netherlands, Bermuda 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. One of the 7 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
