Key Terms

Schedule 13G, Beneficially owned, Shared dispositive power

3 terms

Schedule 13G regulatory

"Item 1. Name of issuer: Personalis, Inc.; form type listed as Schedule 13G"

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 regulatory

"Item 4. (a) Amount beneficially owned: 5,760,627"

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 dispositive power regulatory

"Item 4. (iv) Shared power to dispose or to direct the disposition of: 5,760,627"
