Shareholders of ONE STOP SYSTEMS, INC.
Two shareholders are currently on record for ONE STOP SYSTEMS, 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 13% — the largest recorded stake — followed by Perritt Ultra MicroCap Fund at 0.5%. 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.
