Corporate Governance Specialist

Statement emphasizes manager authority and a disclaimer of beneficial ownership by the reporting entities.

The text includes a written disclaimer that each Reporting Person "disclaims any beneficial ownership" except for pecuniary interest, and it references a Limited Power of Attorney (Exhibit 24) authorizing Heights Capital Management, Inc. to act as agent.

These mechanics clarify attribution and voting power; they do not in the excerpt indicate actionable corporate governance changes or transactions.

"Amount beneficially owned: The information required by this Item 4(a)"

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.
