Corporate Governance Specialist

Filing documents voting and dispositive powers separately, useful for governance analysis.

The filing lists separate metrics: sole voting power 12,377,523 and sole dispositive power 15,768,897. These labels identify who can direct votes versus who can direct sales of shares.

Key Terms

Schedule 13G, Beneficially owned, Sole dispositive power

3 terms

Schedule 13G regulatory

"Item 1. | (a) | Name of issuer: Esperion Therapeutics Inc"

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. | Ownership (a) | Amount beneficially owned: 15,768,897"

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 financial

"(iii) Sole power to dispose or to direct the disposition of: 15,768,897"

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.
