ENV 953/958: Sustainable Business Capstone Consulting Clinics: Company Information

About Company Information

Public companies have shares of stock that are traded on exchanges like the NYSE or NASDAQ. In the US, these companies are regulated by the US Securities Exchange Commission (SEC) and are legally required to file and disclose information that details their financial performance and governance structure, including the 10-K.  Because of these requirements, information on public companies tends to be easier to find.

Tip: knowing the ticker or stock symbol of a company can make your research easier. Find ticker symbols here. 

Private companies do not have shares that are traded on a stock market and typically are not required to disclose their financial performance or other information. Because of this, finding information on these companies can be a challenge. Researching private companies often means you will have to use multiple resources. 

The resources listed on this page can be used for a variety of purposes and often contain more than company financials. 

Databases Featuring Company Information

Find company profiles, financials, SEC Filings, analyst reports, industry research, news, and more with these multi-tasking resources. These can be especially helpful when preparing for interviews.
