Shareholders
2
Two shareholders are currently on record for EFFECTOR THERAPEUTICS, 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 John Hancock Var Ins Tr-Total Stock Market Index Tr, holding 80% — a majority holding — followed by Proathlete Wealth Management LLC at 20%.
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.

EFFECTOR THERAPEUTICS, INC. has no recorded parent company — it sits at the top of its own group structure, with 1 subsidiary recorded beneath it across 1 jurisdiction. 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 1 subsidiary spans United States jurisdiction, 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.
