beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 3,752,046"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

grantor retained annuity trusts financial

"held of record by grantor retained annuity trusts for which Reporting Person serves"

A grantor retained annuity trust (GRAT) is an estate-planning tool where an owner transfers assets into a trust and receives fixed payments back for a set number of years; any remaining assets after that period pass to designated beneficiaries. For investors it matters because it can move future investment growth to heirs while potentially reducing gift and estate taxes — like putting a rising asset in a timed box that pays you first and gives the remaining upside to others.

shared dispositive power financial

"Shared Dispositive Power 71,250.00"

sole voting power financial

"Sole Voting Power 3,680,796.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.
