Introduction to SEC Filings

SEC filings contain useful information about public companies and their finances. Public companies must follow the SEC's disclosure requirements to be listed on major U.S. stock exchanges. The Securities Act of 1933 (Securities Act) requires investors to receive financial and other information about securities offered for public sale, which is intended to prevent misrepresentations and fraud in the sale of securities. The Securities Exchange Act of 1934 (Exchange Act) created the Securities and Exchange Commission and provided the SEC with the power to regulate and oversee the securities industry. Regulation S-K sets out the reporting requirements for SEC filings under both acts. 

Some of the most common types of SEC filings include: 

  • S-1: registration statement under Securities Act of 1933. Includes information about a company's business model and finances. Used by companies filing their initial public offering (IPO) to register with the SEC.
  • 10-K: annual report pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934
  • 10-Q: quarterly report under Section 13 or 15(d) of the Securities Exchange Act of 1934
  • 8-K: current report pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934. Provides updates on significant events that occur in between the 10-K/10-Q (annual/quarterly) updates, such as bankruptcies or changes in senior leadership.


A comprehensive list of SEC forms can be found in the Index to Forms on the SEC website. 

Filings are available for searching on the SEC's official EDGAR website. Paid resources, such as Westlaw, Lexis, and Bloomberg, provide alternate tools to search EDGAR filings. 


EDGAR (Electronic Data Gathering, Analysis, and Retrieval system) provides free access to corporate information and SEC filings from 1994 to the present. Companies are required to file registration statements, periodic reports, and other SEC forms through EDGAR. This section provides an overview of the options available for conducting searches on EDGAR. 

The search options for EDGAR are listed on the SEC's Search Tools page under its Filings section.

Company Filings Search:

Through Company Filings Search, users can search (1) by company name or (2) by ticker symbol or central index key (CIK). The CIK is the identification number given to an individual, company, or government entity filing with the SEC. 

After searching for a specific company, the easiest method to retrieve a particular filing is to filter the results by filing type (e.g., 10-K, 8-K, etc.) and date. A list of the numbers of SEC forms to enter into the filing type field is available in the Forms List

Full-Text Search:

Users can conduct full-text searches from the last four years using the EDGAR Full-Text Search. Note: the four-year timeframe is on a rolling basis (i.e. 4 years from the date of the search).  

Click on "Advanced Search Page" to view additional search options, including the ability to refine by the type of form, limit by date, and restrict the search to a particular company name, central index key (CIK), or standard industrial classification (SIC). 

Boolean and Advanced Searching in the Archive of Historical EDGAR Documents:

Users can conduct Boolean searches across filings from 1994 to present (except for the most recent day) in the Archive of Historical EDGAR Documents. Click on "Search String" for tips on how to formulate Boolean searches.

Latest Filings Received and Processed at the SEC:

Users can browse or search within a listing of the most recent filings for the current official filing date in the Latest Filings Received and Processed at the SEC. This listing includes filings made after the 5:30 pm deadline on the previous filing day. 

For additional information on how to conduct searches on EDGAR, please see the following resources on the SEC's website:

Lexis Advance has a database of SEC filings available for search in its Securities Law practice area.
