What Is EDGAR and How Do Investors Use It to Research Companies?
EDGAR is the SEC's electronic filing and disclosure system. The name stands for Electronic Data Gathering, Analysis, and Retrieval. The SEC's glossary defines it as the computer system for the receipt, acceptance, review and dissemination of documents submitted in electronic format to the Commission. In plain terms, it is the place where public companies and other filers send their required documents to the SEC, and the place where the public can read them.
The SEC's page on accessing EDGAR data states that all companies, foreign and domestic, are required to file registration statements, periodic reports, and other forms electronically. Investor.gov describes the EDGAR database as free public access to corporate information that lets a person research a company's financial information and operations by reviewing registration statements, prospectuses and periodic reports filed on Forms 10-K and 10-Q, along with information about recent corporate events reported on Form 8-K. This entry explains what EDGAR contains, who files there, how the public searches it, how filers get access, what the main filing types are, and which documents are not filed through it.
Two Sides of One System
EDGAR serves two groups of people, and it helps to keep them separate. One group is filers: companies, funds, insiders, institutional managers, filing agents and others who submit documents. The other group is the public: investors, students, analysts, journalists and professionals who read what has been filed.
The SEC describes EDGAR as the primary way for companies and individuals to submit filings to the SEC, and it describes the filings as freely available. The investor on one side of the system and the filer on the other see different screens and use different tools, but they are looking at the same set of documents.
What Is Filed on EDGAR
EDGAR holds registration statements, periodic reports and other forms submitted by public companies and other filers. Investor.gov's guide to using EDGAR lists several filing types that matter to investors. They are worth knowing by name, because the form number is how EDGAR organizes them.
Form 10-K is the annual report. Investor.gov describes it as providing audited annual financial statements and management's discussion of the business. Form 10-Q is the quarterly report, with unaudited quarterly financial statements and updates on operations. Form 8-K is the current report, used to disclose material events or information.
Proxy statements, filed on forms such as PRE 14A and DEF 14A, describe the matters on which shareholders will vote and include compensation and other information about the board and executive officers of a company or fund.
Forms 3, 4 and 5 disclose the holdings and transactions of insiders in all equity securities. Schedules 13D and 13G are filed when a party acquires more than five percent of a class of a company's registered voting securities. Form 13F-HR is the form on which institutional managers disclose holdings on a quarterly basis.
Investor.gov also notes that the database covers mutual funds, exchange-traded funds and variable annuities, in addition to operating companies, and that specialized search tools exist for them.
How the Public Searches EDGAR
The SEC offers several ways to reach the data, and all of them are free. The first is full text search, which the SEC offers at its website. The second is searching by company, which lets a person browse a company's filings. Investor.gov's guide says a person can begin by typing a company's name or ticker symbol into the search bar at the SEC's website.
The third is programmatic access. The SEC states that submissions by company and extracted XBRL data are available through application programming interfaces on its data site, in JSON format. The fourth is bulk data, through index files and archive directories that organize filings by date, company and form type.
The SEC also manages how much load users place on the system. Its fair access guidance says users must moderate their requests to minimize server load, that there is a maximum request rate, and that the SEC reserves the right to limit request rates to preserve fair access for all users. A person who writes a program to collect filings should read the current guidance before doing so.
Reading a Form 10-K
Investor.gov's bulletin on reading these reports notes that most U.S. public companies are required to file a Form 10-K each year. The form is organized into parts and numbered items, and the same item numbers appear in every company's report, which makes it possible to find the same information in different filings.
Part I begins with Item 1, Business, and Item 1A, Risk Factors. It also includes Item 1B, Unresolved Staff Comments, Item 2, Properties, Item 3, Legal Proceedings, and Item 4, Mine Safety Disclosures. Part II includes Item 5, Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities; Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations; Item 7A, Quantitative and Qualitative Disclosures about Market Risk; Item 8, Financial Statements and Supplementary Data; Item 9, Changes in and Disagreements with Accountants on Accounting and Financial Disclosure; and Item 9A, Controls and Procedures. Part III covers Items 10 through 14, which include directors, compensation, relationships and accountant fees. Part IV covers Item 15, exhibits and schedules.
Item 8 requires the company's audited financial statements, which the bulletin describes as including the income statement, balance sheets, statement of cash flows and statement of stockholders' equity, with the accompanying explanatory notes.
The bulletin also gives cautions. If an auditor expresses a qualified opinion or a disclaimer of opinion, investors should look carefully at the concerns. Investors should carefully evaluate material weaknesses in internal controls. The bulletin says that many people view disagreements with accountants as a red flag, and that non-GAAP measures require careful evaluation by investors.
Reading a Form 10-Q
The bulletin states that the Form 10-Q is required to be filed after the first, second and third fiscal quarters. It provides similar but more abbreviated disclosure than the Form 10-K, with fewer item requirements. A reader who knows the structure of the annual report can find the same kinds of information in a quarterly report, in shorter form.
Reading a Form 8-K
Investor.gov's bulletin on the Form 8-K explains that companies must file it promptly and are required to make most 8-K disclosures within four business days of the triggering event, with some requiring earlier filing. The form is organized by numbered items, each tied to a type of event. The bulletin lists examples, including Item 1.01 for material agreements outside the ordinary course of business, Item 1.03 for bankruptcy or receivership, Item 2.01 for major acquisitions or dispositions of assets, Item 2.02 for earnings announcements, Item 4.01 for changes in auditors, and Item 5.02 for director resignations and executive departures. Exhibits such as financial statements, agreements and press releases are filed under Item 9.01.
The information that an 8-K discloses must be material. The bulletin explains that this means there is a substantial likelihood that a reasonable investor would consider the information important.
Finding a Proxy Statement
Investor.gov explains that the definitive proxy statement is filed under the form type DEF 14A, and that the number 14A refers to Section 14(a) of the Securities Exchange Act of 1934. The page states that a company is required to file its proxy statements with the SEC no later than the date proxy materials are first sent or given to shareholders. To view the most recent proxy statement, a reader selects the most recent filing titled DEF 14A.
A Hypothetical Research Walkthrough
A hypothetical shows how the pieces fit together. Suppose a student wants to learn about a company whose stock is publicly traded. The student searches EDGAR by the company's name or ticker symbol and opens the list of filings. The most recent Form 10-K gives the audited annual financial statements and management's discussion. The Forms 10-Q filed since then give unaudited quarterly statements. Any Form 8-K filed in the meantime reports a material event. The latest definitive proxy statement shows what shareholders were asked to vote on and how executives are paid. Forms 4 show whether insiders have been buying or selling shares. This illustration does not describe any actual company and is not a recommendation to buy or sell any security.
The walkthrough shows why the form number matters. Each form answers a different question, and a reader who knows the forms can go to the right document without reading everything.
The Electronic Filing Requirement
The SEC's electronic filing rule is Regulation S-T, Rule 101. Its opening language provides that the filings listed in the rule, including any related correspondence and supplemental information, except as otherwise provided, shall be submitted in electronic format.
The rule also has exceptions. Among the items it allows outside the electronic system are confidential treatment requests and related information, supplemental information requesting protection from public disclosure, shareholder proposals and related correspondence, requests for no-action and interpretive letters, sales and promotional materials submitted for staff review, and documents relating to investigations and litigation. A reader who needs the exact list should consult the rule itself, because the exceptions are specific.
The practical result is that documents which the public relies on, such as annual reports and registration statements, are filed electronically, while some materials that are submitted for the SEC's internal review or that involve confidentiality are handled differently. A document's absence from EDGAR does not by itself mean that nothing was filed.
How Filers Get Access
A person or company cannot simply begin filing. The SEC's glossary describes Form ID as the Uniform Application for Access Codes to file on EDGAR, an online form that individuals and companies must complete to request access to EDGAR.
Once access is granted, a filer is identified by a Central Index Key, usually called a CIK, which the glossary describes as a unique number that the SEC assigns to each EDGAR filer and that is associated with the filer's EDGAR filing account. The glossary also describes the CIK Confirmation Code, or CCC, as an eight-character code that EDGAR uses in conjunction with the CIK that is unique to a filer.
The glossary defines a filer as a person on whose behalf an electronic filing is made, and a filing agent as a financial printer, law firm or other person that uses its own EDGAR access codes to submit a filing or portion of a filing on behalf of a filer. The filer named on a document is therefore not always the person who submitted it.
Every submission receives an accession number. The glossary describes it as a unique reference number generated by the EDGAR system for each submission that can be used to inquire about the status of the submission. The glossary also describes a test filing as a submission made to EDGAR to test the ability to create a filing in an EDGAR-acceptable format.
Filing Hours
The SEC states that EDGAR is available to accept filings from 6 a.m. to 10 p.m. Eastern Time on weekdays, except federal holidays, and that filings made outside those times are processed the next business day.
Structured Data: XBRL and Inline XBRL
Many filings include data that can be read by software as well as by people. The SEC's glossary describes XBRL, which stands for Extensible Business Reporting Language, as an XML-based markup language used for standardized reporting of business information, especially information relating to a company's financial performance. It describes Inline XBRL as a format that allows filers to embed XBRL data directly into an HTML document, eliminating the need to tag a copy of the information in a separate XBRL exhibit.
The practical significance is that the same document can be read by a person on a screen and processed by a program. The SEC's statement that extracted XBRL data is available through its programming interfaces is the public-facing side of this.
EDGAR Next
The SEC changed how filers access EDGAR. Its frequently asked questions describe EDGAR Next as rule and form amendments intended to enhance the security of EDGAR, adopted on September 27, 2024. Under EDGAR Next, individuals present individual account credentials obtained from Login.gov to access filers' EDGAR accounts, and filers authorize account administrators who invite users and manage delegation. The SEC also modernized Form ID and offers optional application programming interfaces for account management.
The SEC states that individual account credentials are for the use of the individual who created them and must not be shared. It lists a compliance date of September 15, 2025. The changes apply to filers who submit filings electronically on EDGAR, including entities such as issuers and filing agents as well as individuals.
These changes affect filers and not readers. A person who only searches and reads filings does not need filer credentials.
Limits of EDGAR
EDGAR is a collection of documents that filers submitted. It is useful because of what it contains, and it is limited by the same fact. An investor who reads a filing is reading what the filer said, and should read it critically, compare it with other sources, and pay attention to the filer's own explanation of risks and uncertainties.
EDGAR also holds only what the filing rules require to be filed there, and the exceptions in Rule 101 mean that some documents are submitted outside it.
Common Misunderstandings
One misunderstanding is that EDGAR is a company. It is a computer system operated by the SEC.
A second misunderstanding is that EDGAR is only for filers. The SEC describes the data as free for anyone to access and download, and investor.gov has a guide for investors who use it.
A third misunderstanding is that only annual reports are filed there. EDGAR contains registration statements, periodic reports, current reports, proxy statements, insider forms, ownership schedules and institutional holdings reports, among others.
A fourth misunderstanding is that every document the SEC receives is public. Rule 101 contains exceptions for confidential treatment requests, no-action letter requests and other items.
A fifth misunderstanding is that the filer who appears on a document submitted it personally. Filing agents use their own access codes to submit filings on behalf of filers.
A sixth misunderstanding is that EDGAR accepts filings at all hours. The SEC states filing hours of 6 a.m. to 10 p.m. Eastern Time on weekdays, except federal holidays.
Key Points
EDGAR is the SEC's system for the receipt, acceptance, review and dissemination of documents submitted in electronic format. The SEC states that all companies, foreign and domestic, are required to file registration statements, periodic reports and other forms electronically, and that anyone can access and download the information for free.
Common filings include the annual report on Form 10-K, the quarterly report on Form 10-Q, the current report on Form 8-K, proxy statements, insider Forms 3, 4 and 5, Schedules 13D and 13G, and Form 13F-HR.
Filers obtain access by completing Form ID and are identified by a Central Index Key and a confirmation code. Filing agents may submit on a filer's behalf. Each submission receives an accession number, and EDGAR accepts filings from 6 a.m. to 10 p.m. Eastern Time on weekdays.
Under EDGAR Next, adopted on September 27, 2024, individuals use Login.gov credentials and account administrators manage access, with a compliance date of September 15, 2025. Regulation S-T Rule 101 requires electronic submission of the filings it lists and contains specific exceptions.
