Institutional Ownership Analyst

Holders report shared voting and dispositive power via managed funds; position size is modest.

The disclosed position is 137,000 shares each, equal to 2.3% of the company's 5,951,030 outstanding shares as of March 30, 2026. The structure is via registered investment advisers, not direct individual holdings.

Materiality is limited by the sub-5% ownership level reported; investor attention may focus on future amendments if aggregated fund ownership or control arrangements change.

Key Terms

Schedule 13G/A, beneficially owned, shared voting power, disclaims beneficial ownership

4 terms

Schedule 13G/A regulatory

"The filing is identified as a joint Schedule 13G/A ownership disclosure"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

beneficially owned regulatory

"Amount beneficially owned: Antonio Ruiz-Gimenez - 137,000"

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.

shared voting power regulatory

"Shared Voting Power 137,000.00 for each reporting person"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
