How to Cite an Annual Report or SEC Filing

TL;DR

Cite the filing, not a summary of it. A company report reference needs the company as author, the fiscal year the report covers, the form type, and a link to the filing on the regulator's site. For US companies that is SEC EDGAR, where every filing has an accession number and a permanent URL, and where the fiscal year end is often not 31 December.

Company reporting is one of the few places where the primary source is easier to reach than the commentary about it. Every filing an SEC registrant makes is public, permanent and addressable, with an accession number and a stable URL. A reference that points at a news summary or a data vendor instead is a reference the reader cannot check.

The worked example is real and was verified against the SEC's own submissions record for Apple Inc. (CIK 0000320193) on 22 September 2026: Apple's Form 10-K for the fiscal year ended 28 September 2024, filed 1 November 2024, accession number 0000320193-24-000123.

What to Collect

On EDGAR, all of this is on the filing index page. The document itself carries the fiscal year end on its cover; the index carries the filing date and accession number.

Quick Reference by Major Style

APA (7th Edition)

APA treats a company report as a report by a group author. The template below is the one the University of Queensland Library publishes for reports, with the report number slot used for the form type and accession number.

Company. (Year). Title of report (Report number). Publisher, if different from the author. URL

Apple Inc. (2024). Form 10-K for the fiscal year ended September 28, 2024 (Accession No. 0000320193-24-000123). U.S. Securities and Exchange Commission. https://www.sec.gov/Archives/edgar/data/320193/000032019324000123/aapl-20240928.htm

In-text: (Apple Inc., 2024)

When the company publishes the report on its own site and is therefore both author and publisher, do not repeat the name: author position only, then the URL.

MLA (9th Edition)

Build the entry from the template of core elements, with the company as author and the regulator's site as the container.

Company. Title of Report. Publisher, Date. Container, URL.

Apple Inc. Form 10-K for the Fiscal Year Ended September 28, 2024. 1 Nov. 2024. EDGAR, U.S. Securities and Exchange Commission, www.sec.gov/Archives/edgar/data/320193/000032019324000123/aapl-20240928.htm.

In-text: (Apple Inc.)

The MLA Style Center's post "How do I cite a company's report?" is the rule on point, and it is the one to follow: if a report was written and published by the same corporate entity, begin with the title and list that entity as publisher; if it was written by one entity and published by another, the writer goes in the author slot and the publisher in the publisher slot. On EDGAR, Apple wrote the filing and the SEC publishes it, so the company stays in the author slot. That post is flagged by MLA as eighth-edition content, so check it against the MLA Handbook, 9th ed.

Chicago (18th Edition)

The Chicago Manual of Style is subscription-only and its free Citation Quick Guide has no filing entry. Murdoch University Library's Chicago guide has a form for reports by government agencies and other organisations; follow that, or whichever guide your department names. The elements are the company, the report title with its fiscal year, the filing date, the regulator and the URL.

Harvard (Cite Them Right)

The University of Sheffield's Harvard guide, which states that it follows Cite Them Right, has a reports entry with a corporate-author variant — one of its own examples is a supermarket's food-surplus and food-waste report, listed under the company name as J Sainsbury (2016).

Corporate Author (Year of publication) Title of report. Paper number (if applicable). Available at: URL (Accessed: date).

Apple Inc. (2024) Form 10-K for the fiscal year ended September 28, 2024. Accession No. 0000320193-24-000123. Available at: https://www.sec.gov/Archives/edgar/data/320193/000032019324000123/aapl-20240928.htm (Accessed: 22 September 2026).

In-text: (Apple Inc., 2024)

That guide also notes that a report with a DOI does not need "Available at" or an access date, because a DOI is stable and a URL is not. Filings have no DOI, so keep the access date.

Referring to a Figure Inside a Filing

A 10-K is hundreds of pages. Point your reader at the part you used, not at the document as a whole:

Missing Elements

No accession number. Non-US registers use their own references. Use the register's document reference and the URL.

The fiscal year is not the calendar year. This is common and it trips people up. Apple's fiscal 2024 ended in September 2024. Put the fiscal-year-end date in the title information so the reader cannot mistake it.

An amended filing. A 10-K/A amends a 10-K. Cite the one you read, name the form type exactly, and say if your point depends on the amendment.

A report only available from a data vendor. Find the register copy. If it genuinely does not exist there, cite the vendor as the container and note the access date.

Common Mistakes

Sources for These Formats

Full style rules: APA, MLA, Chicago, Harvard.

A filing is a report with a corporate author, which the citation generator does handle: choose the report type, put the company in the author field as a single name, and put the form type and accession number in the number field.

Wonders has no index of its own: it searches OpenAlex, Semantic Scholar and Google Patents. Regulatory filings live on the regulator's site, and that is where a reference to one should point.

Frequently asked questions

Should I cite the glossy annual report or the 10-K?

They are different documents. The annual report to shareholders is a designed publication; the Form 10-K is the regulatory filing, and it contains the audited financial statements and the risk factors. Cite whichever you read, name it by its form type, and prefer the filing when you are making a factual claim about the numbers.

Which year goes in the citation?

Both, in different places. The year in the author-date position is the year of publication or filing; the fiscal year the report covers goes in the title information. Apple's fiscal 2024 report covers the year ended 28 September 2024 and was filed on 1 November 2024.

What is an accession number?

SEC EDGAR's unique identifier for a filing, in the form 0000320193-24-000123. It never changes and it pins the exact document, which is why it belongs in the citation alongside the URL.

Can I cite a company report I found on the company's own website?

Yes, and say so. Companies restate and re-post documents, so record the URL and an access date. For anything where accuracy matters, the regulator's copy is the better source, because it is timestamped and immutable.

How do I cite a filing for a company outside the US?

Use the national regulator's filing service rather than a commercial aggregator: Companies House in the UK, SEDAR+ in Canada, ASIC in Australia. Give the company, the document type, the financial year and the register's URL.
