Which entities must receive a filed Schedule 13D?

A filed Schedule 13D must be sent to multiple entities to ensure transparency regarding significant stock purchases. This form, required when someone acquires more than 5% of a company's voting stock, serves to inform the Securities and Exchange Commission (SEC), the issuer of the stock, and the appropriate exchange where the security is listed.

The inclusion of the issuer is crucial because they need to be aware of any potential change in control or interest in their organization, while notifying the SEC is part of compliance with federal regulations. Additionally, informing the appropriate exchange helps maintain orderly markets and prevents potential manipulation.

This multi-faceted disclosure system ensures that all relevant parties have access to critical information regarding ownership and changes that could affect the company's governance and market activity.
