Shareholders

Shareholders of FS BANCORP, INC.
Five shareholders are currently on record for FS BANCORP, 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 7.6% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 3.5%; the remaining 3 shareholders shown hold 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.
