Public Relations

Company Research: Public or Private?

The most important thing to know before you begin your research is whether your company is publicly held or privately held. This information will inform where you search for information. U.S. law requires pubicly held companies to disclose certain information. Most private companies opt not to disclose this information. Thus, if you are researching a small private company, you may need to rely on local news and information sources.
