beneficially owned financial

"Amount beneficially owned: RPD Fund Management LLC - 1,856,981"

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 financial

"Shared power to vote or to direct the vote: RPD Fund Management LLC - 1,856,981"

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.

shared dispositive power financial

"Shared power to dispose or to direct the disposition of: RPD Fund Management LLC - 1,856,981"

pecuniary interest financial

"disclaims beneficial ownership of the reported securities except to the extent of his, her or its pecuniary interest"

Schedule 13G regulatory

"this report shall not be deemed an admission that such Reporting Person is the beneficial owner of the securities for purposes of Section 16"

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.
