Corporate Governance Specialist

Filing documents concentrated ownership and voting authority; no transaction activity is reported.

The Schedule 13G format signals reported beneficial ownership rather than an active acquisition disclosed here. The form lists both sole voting and sole dispositive power over the same share count, clarifying control rights.

Regulatory impact is routine: such holdings trigger ongoing reporting thresholds but the excerpt contains no change-of-control or transaction mechanics.

4 terms

Schedule 13G regulatory

"Item 1. (a) Name of issuer: Rank One Computing Corporation"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

Beneficially owned financial

"Item 4. (a) Amount beneficially owned: 1,414,490"

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.

Sole dispositive power regulatory

"7 | Sole Dispositive Power 1,414,490.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

CUSIP market

"CUSIP Number(s): 753040104"

A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.
