Shareholders of JANUX THERAPEUTICS, INC.
Five shareholders are currently on record for JANUX 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 Vanguard Group Inc, holding 5.7% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 2.1%; the remaining 3 shareholders shown hold smaller stakes.
