Shareholders
2
Two shareholders are currently on record for MUSTANG BIO, 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 Renaissance Technologies, LLC, holding 3.6% — the largest recorded stake — followed by SBI Securities Co., Ltd. at 0.6%.
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.
