CAPSTONE HOLDING CORP.
CAPSTONE HOLDING CORP. is a registered legal entity registered in United States under 2133623, and its current status with Delaware Division of Corporations is active. The company was incorporated on 7 June 1989 and lists its registered address as United States. 5 shareholders are on record for CAPSTONE HOLDING CORP., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.

Shareholders

Shareholders of CAPSTONE HOLDING CORP.
Five shareholders are currently on record for CAPSTONE HOLDING CORP., 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 Citadel Advisors Llc, holding 19.9% — the largest recorded stake — followed by Two Sigma Investments, LP at 13.2%; 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.
