Real World Research: Company Information

Publicly Traded Companies


Securities and Exchange Commission

"Search Companies and Filings" allows you to retrieve real-time filings for a specific company and to find key company information — including its name, address, telephone number, state of incorporation, Central Index Key (CIK) number, Standard Industrial Classification (SIC) code, and fiscal year end.  You can also search for all SEC-registered companies in a particular state. Or you can search for all companies with a specific SIC code. For example, if you enter 7370 in the SIC box, you'll retrieve all SEC-registered companies that fall into the Standard Industrial Classification known as "Services-Computer Programming, Data Processing, Etc."  Once you've found the company you want, you can limit the search results by date (for example, "Prior to 2002-01-01") or by the type of filing (for example, "10-K").

A covered employer must give notice if an employment site (or one or more facilities or operating units within an employment site) will be shut down, and the shutdown will result in an employment loss (as defined later) for 50 or more employees during any 30 day period.

Private Companies


Unlike public companies, private companies are not required to file with the Securities and Exchange Commission (SEC) so the information that can be found in those documents is not necessarily available for companies that are private.  However, private companies deciding to go public file a Form S-1 with the SEC.  This document provides details about the private company, including revenue, profits, executive compensation, legal proceedings, and market share.  Search S-1’s at:
