Shareholders of CONSTELLATION ENERGY CORPORATION
Five shareholders are currently on record for CONSTELLATION ENERGY CORPORATION, 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 Invesco QQQ Trust, Series 1, holding 3.3% — the largest recorded stake — followed by WASHINGTON MUTUAL INVESTORS FUND at 2.7%; 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.
